This paper presents an adaptive branch-and-bound reduction algorithm to globally minimize the sum of linear ratios programs (P), originating from practical issues such as multi-stage shipping problem, computer vision, and others. To find the global optimum of problem (P), a linear relaxation (LR) is derived to yield a lower bound on the optimal value of equivalent problem (P2) of problem (P). In order to further tighten the linear relaxation (LR), we then construct an enhanced linear relaxation (ELR) by adding cuts derived from the solution information of (LR). Moreover, we present an adaptive branching scheme (ABS) that overcomes the drawback of the usual bisection scheme that the optimal solution of the relaxation problem on the selected partitioned rectangle may not be cut off. As a result, ABS leads to a continuous improvement in the lower bound of the optimum of problem (P2). Additionally, the region reduction method is introduced to eliminate regions that do not contain the optimal solution of (P2). By iteratively refining the initial rectangle with the proposed ABS and solving the relaxation problems, the constructed algorithm converges to the global optimum of problem (P). Also, we estimate the maximum number of iterations required for the presented algorithm to achieve an ε -optimal solution. Finally, the validity of the algorithm is verified by numerical comparisons.

To power the fast kicker magnet for releasing ions from the booster accelerator into the Booster–Nuclotron channel of the NICA accelerator complex (JINR, Dubna), generators based on TPI1-10k/75 pseudospark switches were developed, manufactured, and tested. The choice of the switch was due to the unique requirements for the parameters of the output pulse and the impossibility of using solid-state high-voltage switches due to the high radioactive background in the beam bypass areas at the complex. To ensure a front of 500 ns and a pulse plateau duration of 500 ns in order to reduce the influence of the inductance of the magnet conductors of 650 nH, a decision was made to use its bipolar "counter" power supply. Thanks to this, currents of more than 30 kA were obtained at a charging voltage of the forming line of up to 50 kV. The article describes the generator circuits and presents the results of their tests at the Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences, and directly at the workplace at the NICA complex.

For an oriented tree, we compute several graph invariants, including the minimal norm of the generalized inverse and the norm of the Moore–Penrose inverse of its incidence matrix. We present equivalent characterizations of these invariants in terms of the minimal ratios of vector norms related to the oriented tree's incidence matrix. We also provide a method to find the optimal vertex cut and edge cut with respect to these invariants. [ABSTRACT FROM AUTHOR]

Fiber-reinforced polymer (FRP) wraps of reinforced concrete columns might be vulnerable to accidental damage or vandalism. This study aims to develop a simple empirical tool that is based on experimental results to aid in the condition assessment and establish the reduced axial strength ratio (P/Po) of short columns that are loaded at small eccentricities. A total of 47 cylinders, 152 mm in diameter (D), were wrapped with carbon–FRP sheets of 1–3 layers [i.e., producing confinement effectiveness (fcc′/fc′) of 2.3–4.0] and were then subjected to a vertical cut of length (x) that varied from 0.20D to 0.61D at midheight. The loading eccentricity (e) varied from zero to 0.1D. The cut location around the perimeter, for the angle (θ) that was measured from the point of extreme compression, was varied from 0° to 180°. The jacket cuts affect eccentrically loaded cylinders more severely than concentrically loaded ones. As e increased from zero to 0.1D, P/Po reduced from 1.0 to 0.81 for intact samples and from 0.56 to 0.40 for samples with jacket cut. As the cut location traveled around the circumference starting from extreme compression (θ = 0°), less strength reduction was observed where P/Po increased, and at θ = 180° it even exceeded P/Po at zero eccentricity. This suggests a reduction in eccentricity due to a shift in the cross-sectional centroid due to the disturbed confinement on one side. Design models that account for e/D, θ, x/D, and inclined cuts have been developed and calibrated for cylinders of up to 22 slenderness ratio. In addition, a design example is presented.

Athletes with a history of concussion are at a greater risk for lower extremity musculoskeletal injury. Female athletes may be at an even greater risk than male athletes. Previous researchers on postconcussion landing biomechanics have focused on the lower extremities, but the trunk plays a crucial role as an injury risk factor. To compare lower extremity and trunk biomechanics during jump-landing and cutting maneuvers between female athletes with and those without a concussion history. Cross-sectional study. Biomechanics laboratory. A total of 26 athletes (mean ± SD age = 19.0 ± 1.3 years, height = 1.68 ± 0.07 m, mass = 64.02 ± 6.76 kg, body mass index = 22.58 ± 1.97 kg/m2; median [interquartile range] time since most recent concussion = 37.5 months [25.0 months, 65.8 months]) with a concussion history and 38 athletes (age = 19.0 ± 1.1 years, height = 1.71 ± 0.08 m, mass = 64.72 ± 9.45 kg, body mass index = 22.14 ± 1.80 kg/m2) without a concussion history. Peak kinetics (vertical ground reaction force, vertical loading rate, external knee-abduction moment, and external knee-flexion moment) and kinematics (trunk-flexion angle, trunk lateral-bending angle, ankle-dorsiflexion angle, knee-flexion angle, knee-abduction angle, and hip-flexion angle) were obtained during the eccentric portion of jump-landing and cutting tasks. Separate 2 (group) × 2 (limb) between- and within-factors analyses of covariance were used to compare outcomes between groups. We covaried for time since the most recent concussion and the limb that had a history of musculoskeletal injury. Athletes with a concussion history displayed a greater peak knee-abduction angle in their nondominant limb than their dominant limb (P =.01, ηp2 = 0.107) and the nondominant limb of athletes without a concussion history (P =.02, ηp2 = 0.083) during jump landing. They also had less trunk lateral bending during cutting compared with athletes without a concussion history (P =.005, ηp2 = 0.126). Our results indicated landing biomechanics are different between female athletes with and those without a concussion history. This finding may be due to impairments in neuromuscular control postconcussion that may ultimately increase the risk of subsequent lower extremity injury, although further research is warranted given the cross-sectional nature of our study.

Complex methods of physical and chemical analysis: differential thermal analysis (DTA), X-ray phase analysis (XRD), microstructural analysis (MSA), as well as density and microhardness measurements, were used to study the nature of chemical interaction in the Ho-Sb-Te ternary system over the entire concentration range along the following sections:1. Sb2Te3-Ho2Te3, 2. Sb2Te3-HoTe, 3. HoTe-Sb, 4. HoSb-HoTe, 5. Sb2Te3-Ho, 6. HoSb-Te. The projection of the liquidus surface of the ternary system and the diagrams of the state of internal sections were constructed according to experimental data and literature data on binary systems: Sb-Te, Sb-Ho, Ho-Te. It is established that sections (1), (2), (3), (4) are quasi-binary, and (5), (6) are non-quasi-binary sections of the ternary system. The incongruently melting compound HoSbTe3 is formed in the Sb2Te3-Ho2Te3 system and the area of solid solutions based on Sb2Te3 ~ 3‑5 mol% at 300K was found.

Mitosis is a crucial stage in the cell cycle, controlled by a vast network of regulators responding to multiple internal and external factors. The fission yeast Schizosaccharomyces pombe demonstrates catastrophic mitotic phenotypes due to mutations or drug treatments. One of the factors provoking catastrophic mitosis is a disturbed lipid metabolism, resulting from, for example, mutations in the acetyl-CoA/biotin carboxylase (cut6), fatty acid synthase (fas2, also known as lsd1) or transcriptional regulator of lipid metabolism (cbf11) genes, as well as treatment with inhibitors of fatty acid synthesis. It has been previously shown that mitotic fidelity in lipid metabolism mutants can be partially rescued by ammonium chloride supplementation. In this study, we demonstrate that mitotic fidelity can be improved by multiple nitrogen sources. Moreover, this improvement is not limited to lipid metabolism disturbances but also applies to a number of unrelated mitotic mutants. Interestingly, the partial rescue is not achieved by restoring the lipid metabolism state, but rather indirectly. Our results highlight a novel role for nitrogen availability in mitotic fidelity.

In this article it is studied the world of work from a perspective different from the traditional one. It will deal about union collaboration with the State, to problematize what has been the role of a trade union center when integrating into political power. A paradigmatic case, to understand collaborative unionism, corresponds to the experience of the Unique Workers’ Central (CUT) during the government of President Salvador Allende (1970-1973). The general objective is to examine the parastatal unionism of the central to achieve structural changes, as well as the transformations that their class traditions experienced from the political power. The hypothesis of this study is that the CUT transformed its tradition of opposition into parastatal unionism since it joined the political power. This did not imply absolute dependence on the government, nor did it imply moving away from the unión movement. From a point of view different from what has been said, demonstrated his agency and link with the world of work. The role played consisted of collaboration with the government, from the fight for the deepening of democracy and the chilean road to socialism, becoming a relevant actor of the revolution.

To achieve the process of automatic film cutting for cotton and improve the efficiency of cotton precision film hole seeding machine operation, this paper proposes a wireless handle button control method and designs an automatic film and tape cutting system for cotton precision film-laying hole seeder. The system includes electromagnetic integrated valve group, hole opener lifting hydraulic cylinder, membrane pressing hydraulic cylinder, multifunctional hydraulic cylinder for cutting film, strapping support hydraulic cylinder, hydraulic limit sensor, arc-shaped film cutting shovel reset sensor, wireless control handle for film cutting and film cutting controller. The system is based on the VisualTFT platform, equipped with a multi-functional touch screen. By integrating functions such as obtaining the forward distance of the machine, hydraulic control principles, and wireless control models for film cutting and burying, it achieves automatic cutting and burying of ground film and drip tape processes. The experiment verified the working performance of the automatic film cutting and feeding system of the cotton seed precision film mulching hole seeder and the results showed that the average monitoring accuracy of the machine's forward distance was 98.16%; the response time for controlling the film cutting belt and burying film belt was <0.78 s, and the execution time was <2.68 s; the success rate of cutting film strips was 100.00% and the success rate of burying film strips was above 98.33%, which met the operational requirements of automatic film strip cutting for precise cotton seeding film hole planting machines.

The article covers the implementation of anatomy constrained contrastive (ACC) learning networks on a dataset of echocardiographic images with the purpose of segmenting heart chambers for further study. The dataset was partially synthetic, generated using slicing of 3D models of the heart. The images were generated using cycle-consistent generative adversarial networks (CycleGAN) and contrastive unpaired translation (CUT) approaches. By utilizing both CycleGAN and CUT approaches, the generated images captured a wide range of variations in heart chamber segmentation, allowing for a more comprehensive study of the different anatomical features. Proposed approach augments the implementation of ACC learning networks and partially solves the data scarcity problem when it comes to segmentation implementation. [ABSTRACT FROM AUTHOR]

Coal mine excavation faces some new opportunities and challenges under the rapid development of intelligent coal mines. In order to promote intelligent tunneling rapidly and healthily, a comprehensive review about the 20 years development of rapid coal mine tunning in China was conducted, with a view to clarify the development context and trends of tunneling technology, key process technologies and equipment, and integrated equipment in tunneling system. In terms of tunneling technology, the double-roadway excavation has opened up a new way for excavation and anchor in adjacent roadways at the same time. The excavation and anchor synchronization process, and the time-space multi-dimensional synchronous rapid tunneling process break the tradition which contains cutting first, then supporting, and in-time fully supporting, and thus establishes a new excavation process based on cutting and supporting at the same time, the dynamic matching of head face necessary support and permanent support in multi-dimensional space. In terms of key core technologies, the cutting head has gone through three styles: longitudinal axis style, horizontal axis style with full width and full-face style. On the basis of continuous breakthroughs in the high-power density reducer and design concept of whole machine, a series of high-efficiency cutting systems with longitudinal cutting power up to 315 kW and full-width transverse cutting power up to 560 kW has been successfully developed. Supporting operation is developed from the traditional single anchor drilling rig to machine-arm mounted, machine mounted anchor drilling rig, anchor drilling rig with one-key operation, and anchor drilling rig cluster, etc. The number of drilling rigs and operation safety in limited space have been greatly improved, and the operation process has been greatly simplified. Intelligent technologies such as anchor hole identification and automatic planning of anchor path have entered the industrial test stage. The invention of the flexible transport system solves the efficient transfer problem of coal in short distances in tunnel. In terms of integrated equipment configuration, four types of fast excavation modes led by continuous mining machine, bolter miner, roadheader and TBM have been formed. Many different operation lines have been formed under the four rapid excavation modes, that form a full coverage of rapid excavation under various geological conditions. At the system level, intelligent functions such as remote control, centralized control, video monitoring, locking linkage, and personnel approach warning have been realized. Based on the development process of rapid tunneling, the development directions of intelligent tunneling are finally proposed, which contains the theory improvement of multi-dimensional synchronous rapid tunneling in time and space, the data collection for transparent geology based on intelligent excavation, the research of auxiliary operation technology and equipment of tunneling roadway, and the research and development of equipment intelligent technology.

This work is devoted to describing the completion of a posemigroup by cuts. We introduce cut-stable morphisms between posemigroups and obtain that the category RQuant ∧ of quantales with meet and residuals preserving morphisms is a full reflective subcategory of the category CSPoSgr of posemigroups with cut-stable morphisms. As an application, we also characterize other kinds of completions for posemigroups by means of lower cuts. [ABSTRACT FROM AUTHOR]

Derrida’s ‘Le facteur de la vérité’ in The Post Card is memorable for being the philosopher’s most systematic dissection and critique of Lacan’s appropriation and allegorization of literature – in this case Edgar Poe’s ‘The Purloined Letter’ in his inaugural ‘Seminar’ (1956) – to reveal the ‘Truth’ and meaning of psychoanalysis in his ‘return to Freud’. However, the essay’s serious agenda does not preclude a more playful undercurrent, not unusual in Derrida’s writing, in line and in tune with Poe’s ‘analytic tale’ as well as Lacan’s epoch-making interpretation, in which themes and motifs related to card games (and the bid for power implicitly associated with winning) strategically shape the critique and Derrida’s own re-reading of ‘The Purloined Letter’. This essay will explore how Derrida’s numerological moves counter Lacan’s own, opposing even to odd numbers in a restaging of the children’s game in Poe’s tale. ‘Le facteur de la vérité’ will be seen to use game strategies from bridge, while poker, dear to Derrida’s mother, will also be evoked via Hélène Cixous’s reading of ‘Circumfession’ in her Portrait of Jacques Derrida as a Young Jewish Saint. Finally, this reinterpretation of the face-off between Derrida and Lacan will be framed within the larger problematic of the ‘culpable’ Jew (le juif coupable) in Derrida in relation to circumcision as well as to ‘cutting’ or ‘trumping’ (la coupe) in a card game.

Cortex glia in Drosophila central nervous system form a niche around neural cells for necessary signals to establish cross talk with their surroundings. These cells grow and expand their thin processes around neural cell bodies. Although essential for the development and function of the nervous system, how these cells make extensive and intricate connected networks remains largely unknown. In this study, we show that Cut, a homeodomain transcription factor, directly regulates the fate of the cortex glia, impacting neural stem cell (NSC) homeostasis. Focusing on the thoracic ventral nerve cord, we found that Cut is required for the normal growth and development of cortex glia and timely increase in DNA content through endocycle to later divide via acytokinetic mitosis. Knockdown of Cut in cortex glia significantly reduces the growth of cellular processes, the network around NSCs, and their progeny's cell bodies. Conversely, overexpression of Cut induces overall growth of the main processes at the expense of side ones. Whereas the Cut knockdown slows down the timely increase of DNA, the Cut overexpression results in a significant increase in nuclear size and volume and a 3-fold increase in DNA content of cortex glia. Further, we note that constitutively high Cut also interfered with nuclei separation during acytokinetic mitosis. Since the cortex glia form syncytial networks around neural cells, the finding identifies Cut as a novel regulator of glial growth and variant cell cycles to support a functional nervous system.

Cutting maneuvers can be executed at a range of angles and speeds, and these whole-body task descriptors are closely associated with lower-limb mechanical loading. Asymmetries in angle and speed when changing direction off the operated and nonoperated limbs after anterior cruciate ligament reconstruction may therefore influence the interpretation of interlimb differences in joint-level biomechanical parameters. The authors hypothesized that athletes would reduce center-of-mass heading angle deflection and body rotation during the change-of-direction stance phase when cutting from the operated limb, and would compensate for this by orienting their center-of-mass trajectory more toward the new intended direction of travel prior to touchdown. A total of 144 male athletes 8 to 10 months after anterior cruciate ligament reconstruction performed a maximum-effort sidestep cutting maneuver while kinematic, kinetic, and ground reaction force data were recorded. Peak ground reaction force and knee joint moments were lower when cutting from the operated limb. Center-of-mass heading angle deflection during stance phase was reduced for cuts performed from the operated limb and was negatively correlated with heading angle at touchdown. Between-limb differences in body orientation and horizontal velocity at touchdown were also observed. These systematic asymmetries in cut execution may require consideration when interpreting joint-level interlimb asymmetries after anterior cruciate ligament reconstruction and are suggestive of the use of anticipatory control to co-optimize task achievement and mechanical loading.

In 2022, the university press Presses universitaires Blaise-Pascal (Clermont-Ferrand, France) published the first scholarly edition of one of the most prominent works by Jules Verne — Twenty Thousand Leagues Under the Seas. The publisher, ex-professor at the University of Hong Kong, and author of Jules Verne’s English-language biography (2006), as well as numerous works about the writer, William Butcher, describes this edition as the novel’s “restored revision” (texte restaure). This book is the result of many years of research into restoring Jules Verne’s works in their original form, untouched by extensive editorial revisions. It is commonly known that all works in The Extraordinary Voyages collection underwent various amendments and adjustments by the publisher Pierre-Jules Hetzel and later on, by Jules Verne’s son Louis-Jules. W. Butcher previously published English translations and the original versions of certain Jules Verne’s works, including Five Weeks in a Balloon, Journey to the Center of the Earth, The Adventures of Captain Hatteras, Around the World in Eighty Days and others. The pocket size of these editions, however, would not allow to carry out the ambitious editorial project. This review focuses on the core strategies of the Twenty Thousand Leagues Under the Seas’s edition, which W. Butcher refers to as dehetzelisation. The edition also includes a comprehensive scholarly apparatus (an introductory article, rationale, name index, biographical background, detailed chronology of novel writing, annotated bibliography, etc.).

The main aim of this paper is to introduce the notion of (α,β)-level sets with respect to intuitionistic fuzzy normed ideals. We extend the notion of intuitionistic fuzzy normed ideals to the (α,β)-level subsets where α and β are elements in the interval[0,1]. Several related properties for (α,β)-cut of intuitionistic fuzzy normed ideals in a normed ring (NR) will be studied and proven. Further, for any two normed rings NR, NR' with a mapping NR', a relation between the intuitionistic fuzzy normed ideal I of NR and the intuitionistic fuzzy normed ideal f I) the image of I) of NR' will be obtained with the support of their (α,β)-level subsets.

The article presents the history of the search for Louis Boussenard’s novel L’Orpheline de Montmartre undertaken by the author since 2011. The French original of this work was lost, the title is totally unknown to French specialists, and the only evidence of its creation was a pre-revolutionary translation into Russian. The author of the article analyses the translation of E.N. Kiselyov, identifies the narrative elements characteristic of Boussenard, which make it possible to exclude the falsification of authorship, establishes the date of the first publication of the Russian translation, and finds sporadic mentions of this novel in French sources. The analysis of these documents allows to put forward a hypothesis that the novel in question was published in the Parisian daily “La Petite République” and reprinted by an unknown regional socialist newspaper. This hypothesis was exactly confirmed after the digitization in 2015 of the daily socialist newspaper “L’Égalité de Roubaix-Tourcoing.” The result of this discovery was the first book publication of the novel L’Orpheline de Montmartre in French (2017).

The conditional h-vertex (h-edge) connectivity of a connected graph H of minimum degree k > h is the size of a smallest vertex (edge) set F of H such that H − F is a disconnected graph of minimum degree at least h. Let G be the Cartesian product of r ≥ 1 cycles, each of length at least four and let h be an integer such that 0 ≤ h ≤ 2r − 2. In this paper, we determine the conditional h-vertex-connectivity and the conditional h-edge-connectivity of the graph G. We prove that both these connectivities are equal to (2r−h)arh, where arh is the number of vertices of a smallest h-regular subgraph of G.

Braced excavation is one of the important systems used to support soil from collapse during excavation. A braced excavation system may be exposed to seismic load and undergoes more forces through the significant vibration of the surrounding soil in addition to the static and lateral loads of soil and nearby structures. The investigation of the braced excavation under the effect of earthquake behavior is still limited or poorly described. Further, this paper presents a numerical study to evaluate the vertical settlement and horizontal displacement of sheet pile wall embedded in silty clay soil in Baqubah city under the influence of the acceleration time history of the 1940 El-Centro earthquake. The study utilized the software PLAXIS 3D. A three-dimensional analysis of the braced system with dimensions of 14m×6m and an excavation depth of 7m was achieved. Three levels of strut and wale layers were used, and five struts for each level. The penetration depth for the sheet pile wall was 9m. The study showed that the El-Centro earthquake laterally moved the braced excavation system as a block mass due to the existence of the excavation system in soft silty clay. The lateral displacement reached approximately 150mm. The differences in lateral earth pressure on sheet pile wall depth a few seconds before and after the earthquake were very small.

Dual-purpose cereals culturally provide the opportunity to graze a crop during the vegetative phase, and still harvest grain yield at the end of the growing season. It can also help to face climatic changes like frost or dry conditions risk. The aim of the study was to determine the benefits of a dual-purpose barley culture in relation to livestock feed, human nutrition, risk mitigation, and whether a malting variety can also be used for dual-purpose use. A field experiment was carried out in the farm of Nubaria Agricultural Research Station, El-Behera Governorate, Egypt, using five barley varieties during the two successive growing seasons of 2019/2020 - 2020/2021 for dual purpose utilization. No significant differences between the two seasons. The cutting treatment revealed significant or highly significant differences on all studied traits except number of tillers.m-2 and number of spikes.m-2. Green forage weight was highly significantly affected. Concerning normal cultivation, the differences among the five barley cultivars were highly significant for all studied traits except number of spikes m-2. Significant or highly significant differences were found among studied traits concerning cultivars and cutting treatment interaction. Normal cultivation conditions also exhibited that Giza 132 gave the highest grain yield followed by Giza133 and Giza 126. While Giza 2000 gave the heaviest green forage weight followed by Giza 133 and Giza 126 under dual purpose utilization. Moreover, under dual purpose utilization, Giza 126 and Giza 2000 were the best barley cultivars for both green forage and grain yield production. The existing improved dual barley variety conserve the purpose in specified environment as alternative for the green forage demand without sacrificing the grain yield in the rainfed, arid, and semi-arid regions of Egypt.

The reduction of train-induced ground vibrations by different railway lines and by mitigation measures in the propagation path is analysed in a unified approach by two-dimensional finite element calculations where the reduction is expressed as the amplitude ratio between a specific and the reference situation (the surface track without a mitigation measure). In general, there is no reduction at low frequencies, and the reduction becomes stronger with increasing frequency. A maximum reduction ratio of 0.1 at high frequencies is established with an open trench. Reduction ratios between 0.7 and 0.2 have been found for the other situations, filled trenches, walls, plates, and blocks, as well as for railway lines on embankment, in cuts and in a tunnel. Bridges can produce amplifications due to their resonance frequencies, but also strong reductions due to the massive bridge piers. The influence of some parameters has been analysed, the length of the bridge span, the inclination of the embankment and the cut, and the stiffness of the soil and of the tunnel structure. The dynamic track stiffnesses of a surface, bridge and tunnel track have been calculated by the 3D finite-element boundary-element method for comparison with corresponding measurements.

We consider profunctors between posets and introduce their graph and ascent. The profunctors Pro (P , Q) form themselves a poset, and we consider a partition I ⊔ F of this into a down-set I and up-set F , called a cut. To elements of F we associate their graphs, and to elements of I we associate their ascents. Our basic results is that this, suitably refined, preserves being a cut: We get a cut in the Boolean lattice of subsets of the underlying set of Q × P . Cuts in finite Booleans lattices correspond precisely to finite simplicial complexes. We apply this in commutative algebra where these give classes of Alexander dual square-free monomial ideals giving the full and natural generalized setting of isotonian ideals and letterplace ideals for posets. We study Pro (N , N) . Such profunctors identify as order preserving maps f : N → N ∪ { ∞ } . For our applications when P and Q are infinite, we also introduce a topology on Pro (P , Q) , in particular on profunctors Pro (N , N) . [ABSTRACT FROM AUTHOR]

Linear Feedback Shift Registers (LFSRs) have been employed as test pattern generators in BIST for decades; however, an emerging problem with design constraints leads to a lot of improvements in this field. This paper presents a memory-efficient encoding-based method to generate test patterns for a given primitive polynomial LFSR TPG. Here, test patterns generated from LFSR are divided into groups and follow encoding to transform into multiple test patterns. These newly generated encoded test patterns are further divided into transitional and non-transitional blocks which control the bit transitions over encoded values. This weighted driven bit transition also prevents certain bit transitions that reduce the dynamic power as well during the testing process. This TPG technique can be used for generating both pseudo-random test sequence and deterministic pattern generation by allowing fine control over bit transition and appropriate encoder design with the least hardware complexity overhead. The proposed technique has experimented over ISCAS '85 and some sequential part of ISCAS '89 benchmark circuits to validate the superiority in terms of memory efficiency compared to some well-known LFSR reseeding techniques and the hardware complexity reduction during BIST implementation. The proposed encoded test pattern also achieves a minimum of 14% test data volume and toggle control scheme in power reduction. [ABSTRACT FROM AUTHOR]

Productivity of any crop is the potential of the variety when interacting with environmental factors, and especially meteorological ones. Losses due to unfavorable conditions in some years can be up to 50-65,0 %. The purpose of the work was to identify how the productivity of Sudan grass green mass varied through the years with different meteorological conditions, which factors had the greatest effect on it. The study was carried out in 2012-2021 in the conditions of Rostov region. The soil of the plot was ordinary carbonate chernozem. The object of the study was the Sudan grass of Alisa variety, introduced into the State List of Breeding Achievements in 2019. Differences in sowing dates (I-II decades of May) had no effect on green mass productivity and the time of grain maturing. The Sudan grass green mass productivity varied significantly from 36 t/ha to 43 t/ha through the years of study. The year of 2021 was more favorable both in temperature and moisture supply for the formation of the first cut of green mass, and the year of 2018 was favorable for the formation of the second one. The first cut of the green mass was more important and productive. The second cut productivity in 2018 was 84.5 % of the first cut and 45.8 % of the amount of both cuts. In 2021, 35,0 % of the first cut and 26.5 % of the total productivity. The correlation analysis has confirmed that green mass productivity has a close positive correlation with the amount of precipitation (r = 0.79) and a mean negative one with the average air temperature during the vegetation period (r = -0.59).

Lacan’s proposal of the clinical section in 1977 is the most successful conclusion for a dispositive where analytic knowledge is accessible to a group. With the practice of the presentation of patients, Lacan does not perpetuate the medical tradition, rather he subverts it. Historically Lacan recognizes the importance of the birth of a new clinic as a condition for the emergence of analytic discourse. This article aims to show a point of convergence between Michel Foucault and Jacques Lacan, despite the differences. Lacan will make many allusions to The Birth of the Clinic years after its publication. He was a rigorous and constant reader of Foucault’s work, but the only book to which he refers explicitly in his Écrits is The Birth of the Clinic. [ABSTRACT FROM AUTHOR]

Featured Application: The implemented novel solution gives a better insight in grain vitreosity due to a clearer cut which results in cleaner pictures that are easier to read. Also, lower force is needed to conduct the cut. One of the main quality characteristics of cereals, especially wheat is its hardness which is closely related with grain's vitreosity, one of the main quality indicators of a variety. Determination of vitreosity is usually done visually: namely, after the grain is cut with a commercially available grain-cutters, the cut can result in broken or crushed grains which disables the reading and hinders the precision and accuracy. Also, the moment produced from the manual force on the grain-cutter crank, needed to cut the sample of cca. 50 grains placed in the cutter is an average of 30 Nm. Due to the resistance of the grain, yank force appears. This force can cause the whole instrument to be displaced during cutting. To minimize the errors using a commercially available cutter, a new knife/blade has been implemented and tested. The blade of the new knife is turned at the inclination angle of 49° in relation to the cutting objects (grains). This design solution enables achievement of the grain "cutting", not grain "tearing", as observed with the existing commercial design solution. With the proposed new design solution, amount of the moment is reduced to 2.72 Nm and the yank force is completely avoided. Also, a significantly lower amount of the cutting force, on the knife blade is achieved. The results obtained with the new knife gave a better read, were more precise, and the gadget was easier to operate since it demanded lower force to cut the grains. The novelty introduced by this research provided better and more reliable insight into determining the vitreousness of grains. Providing a clearer cut and better readability, this solution goes beyond the current literature by reducing the force required for analysis and speeding up the analysis process.

Elicitors, irrigation regimes and harvest times influence the content, yield and compound of the essential oil (EO) in Salvia officinalis (sage), through changes in biomass dynamics and biosynthetic pathways. A two-year field experiment was conducted to determine if foliar application of putrescine under optimum and deficit stress conditions would favorably affect EO yield, content and profile of sage harvested in spring and summer. The response of dry weight, EO yield and content, myrcene and borneol concentrations to irrigation regime and putrescine concentration can be expressed by a quadratic model. The maximum dry weight (182.63 g m−2) and EO yield (1.68 g m−2) were predicted under irrigation regimes of 9.06% and 27.75% available soil water depletion (ASWD), respectively. The highest EO content (1.05%) was predicted under 3.04 mM of putrescine. Based on results obtained from GC/MS analyses, 25 compounds (mostly monoterpenes) were identified in the EO of sage. Among EO compounds, α-thujone (54.08%), 1, 8-cineole (17.87%), pinocarvone (14.30%), β-thujone (7.97%) and camphor (8.76%) in turn were the most abundant. The concentration of myrcene was higher in spring than summer under the irrigation regimes of 60% and 80% ASWD. The myrcene concentration reached its maximum (4.53%) under the irrigation regime of 86.5% ASWD. The irrigation regimes of 48.03% and 45.6% ASWD caused the highest borneol concentrations of 1.47% and 1.41% by application of 1.5 mM and 2.25 mM putrescine, respectively. All treatments tested on sage, particularly harvest time, can play an important role in the improvement of EO quality and quantity. Averaged over both years, the irrigation regime of nearly 30% ASWD resulted in the highest EO yield harvested with greater quantity and better quality in summer. The EO content and quality changed slightly with the application of putrescine, without significant effect on yield. [ABSTRACT FROM AUTHOR]
