A novel monomer, 9-bis[4-(2-hydroxyethoxy)phenyl]fluorene di(mercaptopropionate), with a highly refractive index, purity, and excellent UV-curable properties, is synthesized through an optimized Fischer esterification process, reacting 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene with 3-mercaptopropionic acid. The structural characterization of this monomer is performed using Fourier-transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, high-performance liquid chromatography, and liquid chromatography-mass spectrometry. The synthesis conditions are optimized using a design-of-experiments approach. UV-curable resins are obtained by incorporating the synthesized monomer as the thiol component. The effects of thiol content on the UV-curing behavior, refractive index, shrinkage, adhesion to the polyethylene terephthalate (PET) foil, and viscoelastic recovery are examined. The thermal properties are assessed using differential scanning calorimetry and thermogravimetric analysis. Field-emission scanning electron microscopy confirms the successful replication of the prism film. In edge-lit light-emitting diode (LED) backlight units, the prism film showed increased luminance with higher thiol monomer content in the UV-curable resin while maintaining stable color coordinates. This novel highly refractive index monomer can be utilized in luminance-enhancing prism films, thereby contributing to future innovations in the display film industry. [ABSTRACT FROM AUTHOR]

The peculiarities of the decoration of gravure imprints on cardboard using fluorescent inks are considered. The influence of the number of fluorescent impurities added to gravure printing ink on the optical indicators of printed image quality, particularly optical density, and gloss, is investigated. Increasing the number of fluorescent impurities added to the ink from 10 to 30% helps to increase the gloss on imprints from 2 to 15 units. Conducted thermogravimetric studies show the resistance of fluorescent imprints to the influence of temperatures during drying in the printing process. The topography of the surface of the substrates and its influence on the quality of imprints is studied. Conducted electron microscopic studies of imprints obtained with inks with different amounts of fluorescent impurities show their uniform distribution on the surface of the substrate. Studies of the fluorescence spectra of the ink and the imprints formed by it confirm the phenomenon of an increase in the intensity of the glow of printed images. The studies confirm the well-known influence of substrate roughness on the smoothness of gravure imprints. It is established that the absence of significant macro irregularities on the surface of Koppargloss FBB cardboard is due to the presence of two coating layers. Analysis of the surface profiles of FBB cardboard shows that its roughness parameter (Ra = 0.424 μm) is three times smaller compared to Incada Silk C GC1 cardboard (the roughness parameter Ra = 1.28 μm), with a single-layer coating. Such a pattern is also preserved on the imprints, which is reflected in their quality accordingly. Studies show that for imprints on GC1 cardboard, the average ΔE value is 2.23, for imprints on FBB cardboard, the average ΔE value is 3.71, which is due to the presence of double coating. The factors that can influence the process of fluorescence of printed images are outlined. The technological characteristics of inks for gravure printing on packaging are described.

To improve the selective adsorption of the target pollutant, this study successfully synthesized chitosan/carboxymethyl cellulose molecularly imprinted hollow vesicles (CS/CMC-MIV) for selective adsorption of acid blue-113 (AB-113). The vesicles were obtained by mixing the carboxymethyl cellulose solution with the chitosan/AB-113 mixture in sequential fast and slow stirring. Benefiting from the molecular imprinting technique, the maximum adsorption capacity of AB-113 by CS/CMC-MIV was 972.7 mg/g, which was 84.8% higher than that of the vesicles without imprinting (526.4 mg/g). The adsorption process could be well in accordance with Langmuir isotherm and pseudo-second-order models. The vesicles exhibited superior stability and reusability, maintaining 92% of the initial adsorption capacity after four adsorption repeats. What's more, CS/CMC-MIV showed excellent selective adsorption ability on mixed dye solutions, which was attributed to the specific recognition sites created during the molecular imprint process. This study provides a facile method to bind dye templates to vesicles and excels at selective dye removal. [ABSTRACT FROM AUTHOR]

Does the experience of upward mobility impact top executives' investment in socially conscious initiatives at the firm level? Despite early theorizing, much remains unknown about how top executives' experiences with upward mobility impact their decisions related to corporate social responsibility (CSR). In this study, we focus on chief executive officers (CEOs) from lower social class origins, who represent the most extreme case of upward mobility among their peers, and examine the effects of their background on the likelihood of helping others. Drawing on upper echelons and social class literature, we theorize that top executives' past—where they come from (i.e. social class origins) and what they have experienced on their climb to the top—influences CSR decisions. We argue that CEOs from lower social class origins develop simultaneous, but at times competing, habitus that influence them to invest more in community-centric but less in employee-centric CSR than their counterparts from middle and upper social class backgrounds. Drawing on trait activation theory, we also predict the moderating influence of the immediate environmental context, namely local levels of poverty and prosperity. Overall, our results support our hypotheses and provide a complex picture of how upward mobility, and its attendant tensions, can affect executive values and CSR. [ABSTRACT FROM AUTHOR]

Polarization reversal and charge trapping under imprint in HfO2-based ferroelectric FET (FeFET) are studied by charge component analysis. By decomposing the effects of spontaneous polarization and charge trapping using the transient current measurement with triangle waves in both metal–ferroelectric–metal (MFM) and metal–ferroelectric–insulator-Si (MFIS) capacitors, we found that V th under imprint in MFIS is determined by both coercive voltage (V c) shift due to imprint and the subsequent modulation of charge trapping at the same polarization. In addition, a comparison of V c shift due to imprint of MFM and MFIS was performed. V c shift of MFIS was found to be in good agreement with that of MFM. This implies that the imprint in FeFET can be predicted from MFM even though FeFET has a complex structure with an interfacial layer. [ABSTRACT FROM AUTHOR]

This work experimentally investigated the wake-up behaviors of hafnium oxide-based ferroelectric capacitors by manipulating the interval time between each characterization cycle. Both Positive-Up–Negative-Down (PUND) and Negative-Down–Positive-Up (NDPU) waveforms were used as the stress and measurement waveforms in the experiments. It was found that the imprint occurs as the total interval time increases to a several-seconds level. However, this only affects the remnant polarization (PR) of ferroelectric capacitors when stressed by NDPU waveforms, since the voltage amplitude saturates under the PUND stress conditions and does not influence the PR. The wake-up behavior has been proved to be caused by the defects redistribution during electrical cycling. Notably, when using PUND waveforms, the change in the interval time can result in different increase rates of PR, indicating the possibility of recovery during the intervals. This recovery leads to a slower wake-up when cycling with a longer interval time. Moreover, it is observed that this PR recovery could reach saturation after several seconds of the interval time. This comprehensive investigation of wake-up and imprint behaviors can provide new insights to evaluate and enhance the reliability of ferroelectric memories. [ABSTRACT FROM AUTHOR]

This study aimed to develop and validate "the Imprint method,", a technique for sampling microbes from chronic wounds while preserving their two‐dimensional spatial organization. We used nylon filters to sample bacteria and compared with sampling using Eswabs in 12 patients. The Imprint method identified a mean of 0.93 unique species more than Eswab (4.3 ± 2.2 and 3.4 ± 1.4 unique species, respectively; mean ± SD; n = 30). Accuracy between the Eswab and the Imprint method was 93.2% and in cases of disagreement between methods, Imprint had a higher sensitivity in 6/8 of the most prevalent species. In vitro validation confirmed that the Imprint method could transfer bacterial colonies while replicating their two‐dimensional organization and the area covered by bacteria on the plate sampled. Clinical testing demonstrated that the imprint method is a rapid and feasible technique that identified more unique bacterial species than Eswab with a good agreement between methods but that Imprint was better at detecting important pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa. The Imprint method is a novel technique that cultures and records the two‐dimensional organization of microbes, providing an alternative or supplement to conventional surface culture using Eswab.

Aim: Addressing therapeutic challenges posed by thyroid nodules classified under Bethesda categories III-IV-V is a primary concern. The aim of this study is to evaluate the diagnostic outcomes of intraoperative frozen section (IFS) when applied to these specific thyroid nodules, alongside evaluating the diagnostic performance of IFS when used in conjunction with concurrent imprint cytology (IC). Materials and Methods: We conducted a comprehensive search in the electronic hospital database to retrieve IFS results and final diagnosis of cases with category III-IV-V thyroid nodules. These patients had undergone nodule resection or partial thyroidectomy with IFS. We gathered information regarding patient demographics, nodule dimensions, and the execution of concurrent IC. Results: Our study comprised 81 eligible patients. Female/male ratio was 3.2. Mean patient age was 43.5 years. Average nodule size was 21.7 mm. IC was conducted in 20 cases as part of the IFS procedure. Sensitivity and specificity of IFS were 71% and 95%, respectively. Positive predictive value (PPV) was 83% and negative predictive value (NPV) was 90%. Diagnostic accuracy of IFS was 88%. We stratified cases into those with and without IC. IFS with IC exhibited a sensitivity, specificity, PPV, NPV of 80%, 93%, 80%, 93%, respectively. In contrast, IFS without IC had sensitivity, specificity, PPV, NPV values of 68%, 95%, 83%, 90%, respectively. Conclusion: Inconsistent pathological assessments and varying malignancy rates present challenges when managing Bethesda category III-IV-V thyroid nodules. In addressing these challenges, IFS emerges as a potential effective method. Nonetheless, IFS exhibits restricted sensitivity in detecting malignancies within Bethesda category III-IV-V nodules. Inclusion of concurrent IC has the potential to improve the precision of IFS in identifying malignancies. A more extensive study in this regard is warranted. [ABSTRACT FROM AUTHOR]

Using the sol-gel and coprecipitation methods, individual oxides of silicon, titanium, zirconium and double oxides TiO2–SiO2, TiO2–ZrO2, ZrO2–SiO2 have been synthesized. Modification with carboxylic acids was carried out at the final stage of synthesis before drying. Their adsorption and acid-base properties, which allowed establish a number of key parameters that determine the texture and features of the hydrate-hydroxyl structure of the samples, were studied in the range pK = 1.3–11.6. It was shown that the formation of a molecular imprint of aromatic carboxylic acids in composites during their sol-gel synthesis is an efficient approach for creating catalysts for the asymmetric Biginelli reaction. Highlights: Using the sol–gel and co-precipitation methods, individual oxides of silicon, titanium, zirconium, as well as double oxides TiO2–SiO2, TiO2–ZrO2, ZrO2–SiO2, modified with carboxylic acids were synthesized. It has been established that the introduction of certain aromatic carboxylic acids leads to a significant decrease in the specific surface area and sorption volume of the composites. The creation of a molecular imprint of carboxylic acids makes it possible to increase the catalytic activity of composites in the Biginelli reaction. [ABSTRACT FROM AUTHOR]

This study employs imprinting theory, cultural capital theory, and upper echelon theory to investigate the influence of the rural upbringing of board chairpersons on corporate R&D (Research and Development) and advertising expenditures, as well as the moderating impact of the chairperson's marketing and financial experience in the competitive market environment. A binary dataset was compiled, comprising 1058 Chinese listed companies and 5434 board chairpersons as samples. Through multiple regression analysis, we established a link between board chairpersons' rural backgrounds and short-term marketing expenditures. The findings indicate that chairpersons' rural upbringing negatively affects R&D and advertising expenditures. Additionally, marketing experience exerts a negative moderating influence on R&D expenditure, whereas financial experience does not exhibit a significant moderating effect. Furthermore, the market growth rate positively moderates the relationship between the chairman's rural background and R&D as well as advertising expenditures. This suggests that the external competitive environment may attenuate the conservative imprint associated with a rural upbringing. This study departs from the conventional paradigm of understanding short-term spending based solely on economic incentives, incorporating non-economic factors rooted in individual cognition and values. It introduces a fresh perspective to the examination of myopic spending and contributes to the exploration of how birthplace impacts corporate decision making. These findings offer a deeper comprehension of how the background of chairpersons influences firms' decision-making behavior, providing valuable insights for top executives in crafting strategies and making informed decisions.

A procedure for evaluating the in-plane anisotropy of a sheet material used in structural elements with their integrity maintained during hardness tests is proposed. An innovative procedure performs anisotropy assessment not by hardness values, but by Vickers and Brinell indentation parameters, as well as by the structural parameters of the material. This procedure can be used to determine an anisotropy level from Vickers hardness, from structural material condition through statistical processing of indentation results, as well as to define the anisotropy of rolled plates, in particular high-strength low-alloy steels as-received, from Brinell imprints. The procedure is also useful in estimating the anisotropy of sheets and even high-strength steel plates whose material exhibits a slightly pronounced anisotropy, when it cannot be determined from imprint measurements, or its correctness controlled by statistical processing of imprint sizes. It is focused on the labor input reduction in determining the in-plane anisotropy of sheet materials as-received with their integrity maintained, on the higher efficiency of research and reliability of anisotropy measurements for high-strength plates with a slightly pronounced anisotropy. The procedure can be instructive in controlling the anisotropy data of sheet materials by indentation parameters. [ABSTRACT FROM AUTHOR]

Lead zirconate titanate (PZT) films with high Nb concentrations (6–13 mol%) were grown by chemical solution deposition. In concentrations up to 8 mol% Nb, the films self-compensate the stoichiometry; single phase films were grown from precursor solutions with 10 mol% PbO excess. Higher Nb concentrations induced multi-phase films unless the amount of excess PbO in the precursor solution was reduced. Phase pure perovskite films were grown with 13 mol% excess Nb with the addition of 6 mol% PbO. Charge compensation was achieved by creating lead vacancies when decreasing excess PbO level; using Kroger-Vink notation, N b T i • are ionically compensated by V P b ″ to maintain charge neutrality in heavily Nb-doped PZT films. With Nb doping, films showed suppressed {100} orientation, the Curie temperature decreased, and the maximum in the relative permittivity at the phase transition broadened. The dielectric and piezoelectric properties were dramatically degraded due to increased quantity of the non-polar pyrochlore phase in multi-phase films; ε r reduced from 1360 ± 8 to 940 ± 6, and the remanent d33,f value decreased from 112 to 42 pm/V when increasing the Nb concentration from 6 to 13 mol%. Property deterioration was corrected by decreasing the PbO level to 6 mol%; phase pure perovskite films were attained. εr and the remanent d33,f increased to 1330 ± 9 and 106 ± 4 pm/V, respectively. There was no discernable difference in the level of self-imprint in phase pure PZT films with Nb doping. However, the magnitude of the internal field after thermal poling at 150 °C increased significantly; the level of imprint was 30 kV/cm and 11.5 kV/cm in phase pure 6 mol% and 13 mol% Nb-doped films, respectively. The absence of mobile V O • • , coupled with the immobile V P b ″ in 13 mol% Nb-doped PZT films, leads to lower internal field formation upon thermal poling. For 6 mol% Nb-doped PZT films, the internal field formation was primarily governed by (1) the alignment of (V P b ″ − V O • •  ) x and (2) the injection and subsequent electron trapping by Ti4+. For 13 mol% Nb-doped PZT films, hole migration between V P b ″ controlled internal field formation upon thermal poling. [ABSTRACT FROM AUTHOR]

Highlights: The strategy of imprint assisted with methylamine acetate effectively ameliorates the morphology of the film, optimize the internal phase distribution, and enhance the charge transfer of the perovskite film. The combination of imprinting with additive engineering improves the phase distribution within quasi-2D perovskite and promote the carrier transport, resulting in a power conversion efficiency of 18.96% with specific good reproducibility. Although two-dimensional perovskite devices are highly stable, they also lead to a number of challenges. For instance, the introduction of large organic amines makes crystallization process complicated, causing problems such as generally small grain size and blocked charge transfer. In this work, imprint assisted with methylamine acetate were used to improve the morphology of the film, optimize the internal phase distribution, and enhance the charge transfer of the perovskite film. Specifically, imprint promoted the dispersion of spacer cations in the recrystallization process with the assistance of methylamine acetate, thus inhibited the formation of low-n phase induced by the aggregation of spacer cations and facilitated the formation of 3D-like phase. In this case, the corresponding quasi-2D perovskite solar cells delivered improved efficiency and exhibited superior stability. Our work provides an effective strategy to obtain uniform phase distribution for quasi-2D perovskite. [ABSTRACT FROM AUTHOR]

Hafnium oxide is found to be a favorable material for ferroelectric nonvolatile memory devices. Its compatibility with complementary metal–oxide–semiconductor processes, the relatively low crystallization temperature when zirconium‐doped, and the thickness scaling are among the advantageous properties of hafnium oxide. Different requirements must be fulfilled for different applications of hafnium oxide. Herein, high‐temperature annealing and operation conditions are analyzed in order to investigate nonvolatile memories for automotive applications. A strong imprint behavior (shift in coercive voltages) is observed after annealing hafnium–zirconium–oxide thin films at temperatures varied between 100 and 200 °C. The imprint behavior is a significant challenge in many applications. Therefore, to reduce/recover the undesirable imprint behavior caused by high‐temperature treatment, two different ways are successfully examined and delineated here: endurance cycling and applying high electric fields.

Purpose: This study aims to advance an international political economy (IPE) perspective that geo-political events can have long-lasting imprint effects on countries and their firms. The study also aims to explore the idea that shared political history and geography combine to create specific structural conditions that shape the international competitiveness of all firms in a region. In particular, the authors consider whether the Monroe Doctrine of 1823, which asserted American influence in the Western Hemisphere, contributed to the creation of institutional structures across Latin America (LA) affecting the strategies of all firms to this day. The authors also illustrate the IPE perspective using the example of the contemporary international competitiveness of LA business groups. Design/methodology/approach: The authors illustrate the IPE perspective using the example of the contemporary international competitiveness of LA business groups. The exploratory framework of this study leads to a proposition about the export performance of Latin American business group affiliates. The authors use firm-level performance data for 32,000 firms across emerging economies to explore the proposition empirically while controlling for alternative explanations. To do this, the authors draw on the World Bank Economic Surveys. Findings: The authors derive a proposition that argues the Monroe Doctrine has had a long-run imprint effect on economic policymaking in LA, resulting in a common, persistent and negative impact on the international competitiveness of firms. The authors find strong and consistent evidence that in terms of export performance, all Latin American firms export less and group affiliates do not outperform independent firms, This finding contrasts with the results for all the other emerging market regions around the world. Research limitations/implications: The main contribution of this study has been to suggest the potential importance of shared regional geopolitical history and geography in explaining firm-level outcomes. However, this study is preliminary and introductory, although the authors seek to control for alternative country-specific explanations of the results. The analysis considers the effects of one particular IPE phenomenon, the Monroe Doctrine, in one particular location: LA. Future work should seek to contrast LA with other geopolitical security and alternative IPE structures. They might also address the time dimension from a historical perspective: is imprinting in LA driven by the length of the Monroe Doctrine arrangements? Practical implications: The most important managerial learning point concerns the relevance of geography and political economy factors for multinational enterprises strategy formation. There is widespread understanding that context is an important determinant of subsidiaries' performance, and that strategies need to be constructed to take account of country-specific characteristics, most importantly, in emerging economies and institutional arrangements. This paper proposes that managers also need to take account of IPE structures, including security arrangements, and to consider the resulting regional as well as national context. Social implications: The analysis suggests that not only the performance of firms, including emblematic firms, but also the socially beneficial spillovers that might be generated from them, are contingent on the regional as well as national characteristics. Thus, business groups in most emerging economies are found to yield better performance and to provide higher levels of social impact, including concerning ESG goals. However, the findings of this study suggest that the former is not true for LA, which, the authors argue, is a consequence of imprinting as a result of the Monroe Doctrine. Further work is needed to establish whether the latter effect is also not true, but if that is the case, then regionally specific policies may be required to address the resulting corporate social shortfalls. Originality/value: The core idea is that geo-political events can have long-lasting imprint effects on countries and their firms: that shared political history and geography create specific structural conditions that shape the international competitiveness of all firms in a region. The authors explore this concept with reference to the Monroe Doctrine, asking whether its assertion of US influence across the Americas contributed to the creation of institutional structures across LA affecting the strategies of all firms to this day.

In piezoelectric transducer applications, it is common to use a unipolar operation signal to avoid switching of the polarisation and the resulting nonlinearities of micro-electromechanical systems. However, semi-bipolar or bipolar operation signals have the advantages of less leakage current, lower power consumption and no additional need of a DC−DC converter for low AC driving voltages. This study investigates the potential of using piezoelectric layers with an imprint for stable bipolar operation on the basis of epitaxially grown lead zirconate titanate cantilevers with electrodes made of a metal and metal oxide stack. Due to the manufacturing process, the samples exhibit high crystallinity, rectangular shaped hysteresis and a high piezoelectric response. Furthermore, the piezoelectric layers have an imprint, indicating a strong built-in field, which shifts the polarisation versus electric field hysteresis. To obtain the stability of the imprint, laser doppler vibrometry and switching current measurements were performed at different temperatures, yielding a stable imprinted electric field of −1.83 MV/m up to at least 100 °C. The deflection of the cantilevers was measured with a constant AC driving voltage while varying the DC bias voltage to examine the influence of the imprint under operation, revealing that the same high deflection and low nonlinearities, quantified by the total harmonic distortion, can be maintained down to low bias voltages compared to unipolar operation. These findings demonstrate that a piezoelectric layer with a strong imprint makes it possible to operate with low DC or even zero DC bias, while still providing strong piezoelectric response and linear behaviour.

In mammals, imprinted genes are required for both fetal development and postnatal growth. A novel candidate imprinted locus was found on human chromosome 16, and maternal uniparental disomy of this locus can cause a lethal developmental lung disease in human newborns. The PMM2 and NARFL genes are located in this region and its homologous region in cattle is on chromosome 25. Currently, there is no report on the genomic imprinting of the PMM2 and NARFL genes. In this study, we demonstrated that PMM2 and NARFL are two paternally imprinted genes in bovines using an SNP‐based method. In addition, two differentially methylated regions of paternal methylation were found in the promoter region and the third intron of the bovine NARFL gene, which may be involved in regulating its imprinted expression. However, we did not find differential methylation in the promoter region or the seventh intron of the bovine PMM2 gene. [ABSTRACT FROM AUTHOR]

Despite the great potential of Hf0.5Zr0.5O2 (HZO) ferroelectrics, reliability issues, such as wake-up, fatigue, endurance limitations, imprint and retention loss, impede the implementation of HZO to nonvolatile memory devices. Herein, a study of the reliability properties in HZO-based stacks with the conventional TiN top electrode and Ru electrode, which is considered a promising alternative to TiN, is performed. An attempt to distinguish the mechanisms underlying the wake-up, fatigue and retention loss in both kinds of stacks is undertaken. Overall, both stacks show pronounced wake-up and retention loss. Moreover, the fatigue and retention loss were found to be worsened by Ru implementation. The huge fatigue was suggested to be because Ru does not protect HZO against oxygen vacancies generation during prolonged cycling. The vacancies generated in the presence of Ru are most likely deeper traps, as compared to the traps formed at the interface with the TiN electrode. Implementing the new procedure, which can separate the depolarization-caused retention loss from the imprint-caused one, reveal a rise in the depolarization contribution with Ru implementation, accompanied by the maintenance of similarly high imprint, as in the case with the TiN electrode. Results show that the mechanisms behind the reliability issues in HZO-based capacitors are very electrode dependent and simple approaches to replacing the TiN electrode with the one providing, for example, just higher remnant polarization or lower leakages, become irrelevant on closer examination.

This mini-review focuses on current knowledge regarding maternal regulation of the paternal genome in early embryos of mammalian livestock species. Emphasis has been placed on regulatory events described for maternally imprinted genes and further highlights transcriptional regulation of the postfertilization paternal genome by maternal factors. Specifically, the included content aims to summarize genomic and epigenomic contributions of paternally expressed genes, their regulation by the maternal embryo environment, and chromatin structure that are indispensable for early embryo development. The accumulation of current knowledge will summarize conserved allelic function among species to include molecular and genomic studies across large domestic animals and humans with reference to founding experimental animal models.

Niemann–Pick disease type A (NPDA, MIM: 257200) is an autosomal recessive sphingolipidosis caused by lysosomal acid sphingomyelinase (ASM) deficiency. A cluster of genes located at chromosome 11p15 have been reported to be imprinted genes, such as TSSC5, TSSC3, and ZNF215 that flanking SMPD1 gene. It was reported by a few recent studies that SMPD1 gene was paternally imprinted and maternally preferentially expressed. A five-month-old boy with severe anemia, hepatosplenomegly and bone marrow foam cells was recruited from a complete cousin couple. To determine whether boy suffered from NPDA, ASM activity and SMPD1 gene sequencing were performed on available individuals of this pedigree including the proband, his parents and sister. The ASM activities of proband and parents showed deficiency (17.7 nmol/h/g-protein) and about 50% decreased (83.3 nmol/h/g-protein), respectively, compared with normal controls (204.5 nmol/h/g-protein). SMPD1 gene sequencing in the proband revealed a homozygous mutation c.1420_1421del, which leads to an open reading frameshift and a premature stop codon. The parents and some individuals of this family demonstrated heterozygous mutation at this locus. To investigate whether SMPD1 gene is imprinted as reported previously, the expression of RNA level was studied in the whole family members available. The members with heterozygous mutation for c.1420_1421del showed that both paternal and maternal inherited alleles were expressed. This study reported a c.1420_1421del mutation in SMPD1 gene which caused ASM activity decrease and this locus was biallelically expressed in heterozygous subjects implicating SMPD1 is not imprinted in this family.

In this letter, NH3 plasma treatment was utilized to improve the ferroelectric property of widely used TiN/HfxZryO2(HZO)/TiN capacitors. The developed metal-ferroelectric-metal (MFM) structure shows high remnant polarization (Pr) of $30 ~\mu \text{C}$ /cm2 after 10-min NH3 treatment at bottom TiN electrode. Materials characterization were subject to investigate the behind mechanism. A higher ferroelectric o-phase formation in NH3-treated HZO device is revealed by grazing incidence X-ray diffraction (GIXRD). In addition, the high-resolution transmission electron microscopy (HRTEM) indicates that the NH3 treatment optimizes the interface quality by restraining of the interfacial layer (IL) including intrinsic TiOxNy dead-layer and non-ferroelectric layer. Furthermore, the improved interface engineering also suppressed the imprint effect, which prompts the retention improvement of TiN/HfxZryO2/TiN ferroelectric capacitors. [ABSTRACT FROM AUTHOR]

Hafnia-based ferroelectrics have greatly revived the field of ferroelectric memory (FeRAM), but certain reliability issues must be satisfactorily resolved before they can be widely applied in commercial memories. In particular, the imprint phenomenon severely jeopardizes the read-out reliability in hafnia-based ferroelectric capacitors, but its origin remains unclear, which hinders the development of its recovery schemes. In this work, we have systematically investigated the imprint mechanism in TiN/Hf0.5Zr0.5O2 (HZO)/TiN ferroelectric capacitors using experiments and first-principles calculations. It is shown that carrier injection-induced charged oxygen vacancies are at the heart of imprint in HZO, where other mechanisms such as domain pinning and dead layer are less important. An imprint model based on electron de-trapping from oxygen vacancy sites has been proposed that can satisfactorily explain several experimental facts such as the strong asymmetric imprint, leakage current variation, and so forth. Based on this model, an effective imprint recovery method has been proposed, which utilizes unipolar rather than bipolar voltage inputs. The remarkable recovery performances demonstrate the prospect of improved device reliability in hafnia-based FeRAM devices. [ABSTRACT FROM AUTHOR]

Moulages are contact media – images made by contagion in the most literal sense: their production relies on a process in which the object to be reproduced is touched by the reproducing material. In the case of dermatological moulages, the plaster touches the infected skin of the sick and, once dried, serves as the negative form for the waxen image of a disease. Focussing on the collection of the Hôpital Saint-Louis in Paris, the article situates the production of dermatological moulages within the visual culture of 19th-century medicine and raises the question how an ancient technique of image production could become such a prevalent tool for the documentation of skin diseases during a period usually associated with the rise of scientific medicine and a reconsideration of theories of contagion in medical aetiology.

We investigate the different interpretations related to the metaphorical imprint of climate change in English and French media discourses. This cross-linguistic perspective is motivated by the particularities of both languages which have been assumed to promote different understandings of climate change-related concepts. We focus on the metaphor carbon footprint whose meaning can be compared to another climate change metaphor in English: fingerprint. These two source domains share a highly specific and concrete meaning interpreted from lexical constructions enabled by the English language. In French, however, such a specification cannot be interpreted from the meaning of the metaphor empreinte carbone (carbon imprint) which defines a similar concept. We rely on visual representations of these metaphorical expressions in English and French to discuss the characteristics associated with each source domain: we show that visual metaphors can contradict expectations emerging from the interpretations of verbal metaphors.

Superhydrophobic metallic surfaces with mechanical stability as well as self-cleaning and anticorrosion functions are highly desirable because of their promising applications in various aspects. Large apparent water contact angles (≥150°) on metal surfaces are usually realized by high surface roughness and low surface energy. However, rough nanoscale features and low-energy coatings are prone to wear, causing degradation of the local wetting property during service. Herein, we develop a low-cost and scalable fabrication methodology to prepare composite superhydrophobic surfaces (water contact angle ∼154.7± 2.3° and sliding angle ∼1.2 ± 0.2°) by integrating a micropatterned amorphous alloy frame with functionalized nanoparticles. Amorphous interconnected microwalls provide augmented resistance against abrasion, whereas spray-coated nanomaterials residing within the frame impart water repellency. Metallic surfaces can withstand abrasion against sandpaper for 40 m under a local pressure of 120 kPa, before losing their perfect superhydrophobic performances. The composite surfaces also maintain its water repellency after mechanical bending, knife scratching, water impact jetting, ultraviolet (UV) irradiation, and acid immersion. We envisage that the design strategies here provide a practical route to manufacture water-repellent surfaces with metallic glass in harsh nautical applications. [ABSTRACT FROM AUTHOR]

We provide evidence of delayed attention and inaction in response to COVID-19 in countries that did not experience SARS in 2003. Using cross-country data, we find that individuals in countries that had SARS infections in 2003 searched more intensively for COVID-19-related information on Google in late January 2020, the time of the first known outbreak in Wuhan, China. Early attention to the novel virus, as measured by Google searches, is associated with deeper stock market drops in countries with SARS experience. In contrast, people in countries without SARS experience started to pay more attention much later, in March. Moreover, governments in these countries responded significantly more slowly in implementing social distancing policies to combat domestic COVID-19 outbreaks than governments in countries with SARS experience. Moreover, such early responses of individuals and governments in countries with SARS experience are prevalent within continent, even in non-Asian countries. Furthermore, people in countries with SARS experience are more compliant with social distancing rules. These timely attention and proactive responses of individuals and governments are more pronounced in countries that reported deaths caused by SARS, which left deeper imprints. Our findings suggest that the imprint of similar viruses' experience is a fundamental mechanism underlying timely responses to COVID-19. This paper was accepted by Haoxiang Zhu, finance.

Lurch is a Coragyps atratus who was raised in captivity and imprinted on humans. He was an education animal at the Silver Springs Zoo until its closure. Lurch was moved to the Central Florida Zoo and has been feather picking and self-mutilating since then. Self-injury is not well documented in raptors and few treatments have been explored. It is often caused by stress of some sort and is not seen in the wild. These observations were conducted in order to observe the environmental factors that influenced these behaviors in Lurch. In an attempt to curb his feather picking, Lurch was introduced to a Polyborus plancus, and he attacked her. They were separated but housed next to each other. He has been showing signs of aggression towards her thereafter. Lurch was observed in 2019 from January 12 to April 11 in two-hour intervals. Lurch showed no significant change in feather picking with P. plancus present. P. plancus was moved to a different enclosure on January 29th. There was no significant change in self-injury when courting behaviors were observed on February 14th, 24th, 26th, and March 7th, and no significant change in selfinjury with interaction with current enrichment items. There was a significant inverse correlation between keeper presence and self-injury. A blocking vest was introduced on March 24th; a significant decrease in self-injury was observed while wearing the vest. Further testing is needed to determine the reason for the correlation and confirm the decrease due to the blocking vest. [ABSTRACT FROM AUTHOR]

The discovery of the HfO2‐based ferroelectric films has opened new opportunities for using this silicon‐compatible ferroelectric material to realize low‐power logic circuits and high‐density non‐volatile memories. The functional performances of ferroelectrics are intimately related to their dynamic response to external stimuli, such as electric fields at finite temperatures. In the case of HfO2‐based films, the time‐dependent imprint and wake‐up effect, which distinguish them from conventional ferroelectrics, play important roles in understanding the remaining reliability issues, such as insufficient endurance. In this study, the time‐dependent imprint process is carefully investigated using Hf0.5Zr0.5O2 (HZO) films with different ferroelectric properties and defect density. The amount of redistributed charge, which causes imprint during polarization retention, is affected by the remanent polarization of the ferroelectric layer, suggesting that the depolarization field corresponding to the remanent polarization generates and works as a driving force of charge redistribution. The time‐dependent measurement of the imprint distinguishes the origins of charge redistribution processes, which have different time constants. In addition, the correlation between the amount of redistributed charge and the dielectric relaxation of the HZO films is discussed. Correlations are identified between the redistributed charge and the dielectric relaxation, indicating that the mobile charge contributes to the time‐dependent imprint. [ABSTRACT FROM AUTHOR]

We report piezo force microscopy (PFM) investigations on the ferroelectric switching characteristics of spherical and rod shaped non-interacting nanocrystalline BaTiO3 (BTO). Polarization-voltage hysteresis loop (P-E hysteresis loop) measurement shows that the strong polarization reversal observed for the nanorod (NR) shaped BTO than the spherical nanoparticle (NP). Asymmetric P-E loop is observed for all kind of BTO NRs. From the PFM spectroscopy and ferroelectric switching studies reveal that the defect dipoles present in the BTO NR at below 60 nm have no significant effect on the asymmetric P-E hysteresis loop. It is strongly depends on the strain between the substrate and BTO NRs. [ABSTRACT FROM AUTHOR]

Augmented reality (AR) enhancing the existing natural environment by overlaying a virtual world is an emerging and growing market and attracts huge commercial interest into optical devices which can be implemented into head-mounted AR equipment. Diffractive optical elements (DOEs) are considered as the most promising candidate to meet the market's requirements such as compactness, low-cost, and reliability. Hence, they allow building alternatives to large display headsets for virtual reality (VR) by lightweight glasses. Soft lithography replication offers a pathway to the fabrication of large area DOEs with high aspect ratios, multilevel features, and critical dimensions below the diffractive optical limit down to 50 nm also in the scope of mass manufacturing. In combination with tailored UV-curable photopolymers, the fabrication time can be drastically reduced making it very appealing to industrial applications. Here, we illustrate the key features of high efficiency DOEs and how the SMILE (SUSS MicroTec Imprint Lithography Equipment) technique can be used with advanced imprint photopolymers to obtain high quality binary DOEs meeting the market's requirements providing a very versatile tool to imprint both nano- and microstructures.

The main challenge in ferroelectric (FE) random access memory (FRAM) scaling is to maintain a high polarization density on the vertical sidewall of 3-D FE capacitors. Two simple and effective methods—stress engineering and optimized interface orientation—are proposed to facilitate the preferential transition from the tetragonal to the orthorhombic phase for ferroelectricity. Four FE phase-progressive experiments were conducted for 2-D/3-D FRAMs with external stress sources and an interfacial layer (IL). Both 2-D and 3-D FRAMs show the wake-up free feature with the presence of both the external stressor and the optimized IL. To extract the sidewall polarization of 3-D FRAM, a set of testkeys was designed and studied. The 3-D FRAM shows an initial sidewall with good reliability and durability with Pr = 18μ C/cm2 and endurance of up to 109 cycles. Furthermore, the retention test with the read mode of P0,switch and P1,switch at 85 °C was investigated, and the imprint effect was proved to be the main cause of retention loss.

Using a large sample of 10,668 small‐ and medium‐sized private Chinese enterprises over the 2006–2014 period, this study investigates the effect of the social class background of entrepreneurs on firm corporate environmental responsibility (CER) activities. The research question is developed using the concepts of imprinting theory. We measure the social class background of entrepreneurs as the level of occupational prestige held by the individual prior to starting a business. Results show that entrepreneurs drawn from the upper and lower social classes show a preference for the pursuit of environmental governance investment strategies. Moderating influences based on political capital and institutional environment are also explored. The theory and findings highlight that the social class background of entrepreneurs has a lasting and varying impact on the CER activities of a firm. The results are robust to a variety of sensitivity tests. The study extends our understanding of how and why enterprise CER behaviour varies, particularly in the context of Chinese private firms, and offers important implications for the task of sustainable development by enterprises.

Ferroelectric (FE)-HfO2-based FETs (FEFETs) are one of the most promising candidates for emerging memories. However, the FE material suffers from a unique reliability phenomenon known as imprint: the coercive voltage shifts during data retention, which has been regarded as a major issue for memory operation, while the mechanism causing it is still under research. In this article, imprint and its recovery in FE-HfO2 are investigated in detail by comprehensive electrical measurements to reveal its underlying mechanism including the cause of asymmetric coercive voltage shifts. The recovery measurements clarify that domain switching is indispensable for the recovery from imprint. The subloop imprint effect shows that imprint and its recovery must be independent for each domain. In addition, switching time measurements and corresponding fitting results with the nucleation-limited-switching (NLS) model strongly indicate that imprint is caused by domain-seeds-pinning. Based on these results, we conclude that charge trapping and detrapping affecting activation barriers for domain switching, accompanied by domain switching, is responsible for imprint and its recovery.

Context: Intraoperative pathological assessment provides valuable information in a patient's diagnosis and management. Touch imprint/crush cytology is simple, rapid, and cost-effective. Also, imprint smears give excellent cytomorphology. Aims: To assess the utility and feasibility of intraoperative cytology technique as a rapid and reliable method for diagnosis and to compare sensitivity, specificity and diagnostic accuracy with histopathology. Materials and Methods: Cytology smears were collected intraoperatively from 52 cases of suspected/proven malignancy. From tumors, surgical margins, lymph nodes; crush, imprint, and scrape smears were prepared. Smears were taken from specimens before formalin fixation and stained with rapid ultrafast Papanicolaou stain. The slides were compared with the histopathology report which is the gold standard. Statistical Analysis: Sensitivity, specificity, and diagnostic accuracy were used for statistical analysis. Results: Intraoperative cytology report could be given in time for the surgeon to modify margins of resection and the extent of lymph node dissection. It helps the surgeon to modify surgery. The diagnostic test evaluation showed satisfactory results. Conclusion: Intraoperative imprint/crush cytology is a simple, inexpensive, rapid, accurate cytodiagnostic technique in the diagnosis of cancer where frozen section facilities are not available. It can also be used to assess the clearance of surgical margins. [ABSTRACT FROM AUTHOR]

This paper documents a strong delayed response to COVID-19, which is caused by the SARS-CoV- 2 virus in countries that did not encounter the SARS disease in 2003. The SARS outbreak was caused by a similar virus, SARS-CoV-1. Individuals in countries that developed SARS infections in 2003 search more intensively for COVID-19-related information on Google during the first outbreak of COVID-19 in Wuhan, China, in late January 2020. Governments in countries that have not experienced SARS respond significantly slower in implementing containment measures to combat COVID-19 than countries that have experienced SARS. Furthermore, the timely responses of individuals and governments are more pronounced in countries that reported deaths caused by SARS, which left deeper imprints. Consequently, COVID-19 case numbers and mortalities have been substantially higher in countries that did not experience SARS deaths. Our findings suggest that the imprint of the early experience of similar viruses is a fundamental mechanism underlying timely responses to COVID-19. [ABSTRACT FROM AUTHOR]

The preservation of old industrial buildings implies their treatment as reused elements for the development of the dynamics of today's society, in a second life where their recovery for citizenship implies a social value added to their historical-cultural importance. But this narrative is not complete without considering those intangible aspects that, unfortunately, have been lost over time and shape a memory of absences. This article proposes a reflection on the specific imprint left by the presence of Spanish tobacco factories in the urban landscape. It examines their different dimensions as industrial heritage in relation to the territory, the city, their architectural formalisation and the dynamics of the cigarette-makers as key workers. In this way, the importance of the activity of these factories in the cities in which they were located established a series of tangible and intangible relationships, both in their immediate surroundings and in the whole city.

Ferroelectric films suffer from both aging and degradation under high ac‐field drive conditions due to loss of polarization with time. In this study, the roles of defect chemistry and internal electric fields on the long‐term stability of the properties of piezoelectric films were explored. For this purpose, lead zirconate titanate (PZT) films with a Zr/Ti ratio of 52/48 doped with Mn‐ (PMZT) or Nb‐ (PNZT) were deposited on Pt coated Si substrates by the sol‐gel method. It was demonstrated that the magnitude of the internal field is much higher in PMZT films compared to PNZT films after poling in the temperature range of 25‐200°C under an electric field of −240 kV/cm. The development of the internal field is thermally activated, with activation energies from 0.5 ± 0.06 to 0.8 ± 0.1 eV in Mn doped films and from 0.8 ± 0.1 to 1.2 ± 0.2 eV in Nb doped films. The different activation energies for imprint suggests that the physical mechanism underlying the evolution of the internal field in PMZT and PNZT films differs; the enhanced internal field upon poling is attributed to (a) alignment of oxygen vacancy—acceptor ion defect dipoles ((MnTi″-VO··)x, (MnTi′-VO··)′) in PMZT films, and (b) thermionic injection of electron charges and charge trapping in PNZT films. In either case, the internal field reduces back switching, enhances the remanent piezoelectric properties, and dramatically improves the aging behavior. PMZT films exhibited the greatest enhancement, with reduced high temperature (180°C) aging rates of 2%‐3%/decade due to improved stability of the poled state. In contrast, PNZT films showed significantly larger high temperature aging rates (15.5%/decade) in the piezoelectric coefficient, demonstrating that the fully poled state was not retained with time.

As compared with Si as the substrate, ferroelectric (FE) HfZrOx with orthorhombic phase on Si0.56Ge0.44 substrate was found to demonstrate improved FE characteristics. Through the incorporation of Ge into the silicon substrate, remanent polarization (${P}_{r}$) can be further enhanced by 58% magnitude to $15~\mu \text{C}$ /cm2. Moreover, devices on Si0.56Ge0.44 show significant reliability enhancement in terms of negligible ${P}_{r}$ degradation up to 107 cycles under ±4 MV/cm with 10-kHz bipolar stress and desirable retention up to 104 s arising from smaller imprint effect against time at 85°C. The major role of Ge introduction into the substrate is to suppress the formation of the interfacial layer (IL) between HfZrOx/substrate and further reinforce the quality of the IL. The suboxide IL of the enhanced quality can be explained by the fact that it is too thin to trap charges while less vulnerable to defect generation due to stronger bonding with fewer oxygen vacancies. The results suggest that as the technology advances from Si into SiGe platform, HfZrOx-based devices possess more reliable ferroelectricity for metal–FE–semiconductor (MFS) gate-stack for the next-generation FeFET.

We have succeeded in fabricating prism structure on 65” GLGP with both imprint and film lamination methods. [ABSTRACT FROM AUTHOR]

In this essay, I undertake an analysis of the first exhibition curated by Didi -Huberman, L'Empreinte (Imprint), which took place in Centre Pompidou in 1997. In this project, the French philosopher and art historian intentionally bypassed the usual products of artmaking, instead choosing to focus on what is left alongside this process. The project in Centre Pompidou transferred the technique of imprinting into the context of art of the 20th-century, investigating the tactile transmission of form from one surface to another. I will examine how Didi-Huberman's attempt was influenced by the notion of survivance of forms, formulated by Aby Warburg, and how it offers an alternative to traditional approaches to original/ copy issue.

In the mouse, while either X chromosome is chosen for inactivation in a random fashion in the embryonic tissue, the paternally derived X chromosome is preferentially inactivated in the extraembryonic tissues. It has been shown that the maternal X chromosome is imprinted so as not to undergo inactivation in the extraembryonic tissues. X-linked noncoding Xist RNA becomes upregulated on the X chromosome that is to be inactivated. An antisense noncoding RNA, Tsix, which occurs at the Xist locus and has been shown to negatively regulate Xist expression in cis, is imprinted to be expressed from the maternal X in the extraembryonic tissues. Although Tsix appears to be responsible for the imprint laid on the maternal X, those who disagree with this idea would point out the fact that Tsix has not yet been expressed from the maternal X when Xist becomes upregulated on the paternal but not the maternal X at the onset of imprinted X-inactivation in preimplantation embryos. Recent studies have demonstrated, however, that there is a prominent difference in the chromatin structure at the Xist locus depending on the parental origin, which I suggest might account for the repression of maternal Xist in the absence of maternal Tsix at the preimplantation stages.

ABSTRACT A structured broad-band photonic film is fabricated by a novel method using multiple gradient UV-induced polymerization in the presence of cholesteric liquid crystals (CLCs). Here, imprinting and broadening of the reflection band of chiral nematic mesophase cells are achieved via controlled UV polymerization. The intensity gradient of UV light is modified by the distance between UV lamp and sample cell, which affects the polymerization rate and leads to the formation of imprinted helical constructions with different pitches. In this study, a comparison of new design process with traditional UV polymerization process is carried out. After seven cycles of gradient UV polymerization, the imprinted photonic construction exhibited a broadened reflection band and Bragg reflection, even for isotropic materials. Because of this, the reflection bandwidth showed a 70% improvement. Additionally, two stacked imprinted cells with different pitches can reflect incident light with a bandwidth over the visible wavelength range of 480-680 nm. A broad-band photonic polymer film can be imprinted using multiple gradient UV photopolymerization in the presence of CLCs. Forming a UV intensity gradient and controlling the rate of photopolymerization are key factors in broadening the reflection band. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym.
