Abstract

The exceptional magnetic, optical and phononic properties of Yttrium Iron Garnet (YIG) make it unique for spin-wave based and photonic applications. Yet, nanostructuring crystalline YIG and manipulating its magnetism in a non-destructive way is an outstanding challenge, and so far mostly limited to two-dimensional capabilities. Here, we show that irradiation of single-crystal YIG films with a focused UV laser drives a stable, giant enhancement of the perpendicular magnetic anisotropy, preserving the crystalline quality. This modulation is highly confined at the nanoscale in both the lateral and vertical directions, and its extension within the volume can be finely tuned with a continuous depth-control. By harnessing these three-dimensional anisotropy profiles, we demonstrate a large tuning of the spin-wave band structure, volume spatial localization, and non-reciprocity, realizing proof-of-principle 3D magnonic crystals. This straightforward, single-step, laser nanofabrication of three-dimensional magnetic systems based on crystalline YIG thin films opens the way to design novel functions in magnonic and magneto-optic devices., Comment: 17 pages, 5 figures

Abstract

Introduction: The objective of the current study was to design and pilot-test a nonverbal intelligence test for children and adolescents with visual impairment (i.e., blindness and low vision) aged 10 to 16 years. Method: A three-dimensional haptic matrix test of nonverbal cognitive abilities (3-DHMT-CA), initially developed for adults with visual impairment, was adapted and administered to 25 juveniles with severe low vision or blindness and 25 sighted peers. The test consisted of 22 tactual matrices with a missing element, and juveniles were asked to understand the logical scheme underlying each matrix and to complete it. Convergent validity was assessed in the sighted group with the Standard Progressive Matrices. Divergent validity was measured with the Verbal Comprehension Index (VCI) and the Working Memory Index (WMI) of the Italian version of the Wechsler Intelligence Scale for Children--Fourth Edition. Between-group differences were analyzed with Student's t-test and ANOVA. Results: Results show a high correlation with the convergent measure (with the Standard Progressive Matrices), and the moderate correlations with divergent measures (VCI and WMI). Between-group differences showed significantly higher scores for sighted peers than juveniles with visual impairment at 3-DHMT-CA, and non-significant differences at VCI and WMI. Discussion: This haptic nonverbal cognitive test showed good psychometric properties, but it needs to be validated in a larger sample with a qualitative analysis of solution strategies because juveniles with visual impairment seem to use different verbal and working memory strategies. Implications for Practitioners: The 3-DHMT-CA and the haptic two-hands modality seem to be suitable to test nonverbal cognitive abilities in juveniles with visual impairment. Practitioners should focus on empowering verbal and working memory abilities, since they may affect nonverbal cognitive abilities as well.

Abstract

Micron-thick boron films have been deposited by Pulsed Laser Deposition in vacuum on several substrates at room temperature. The use of high energy pulses (>700 mJ) results in the deposition of smooth coatings with low oxygen uptake even at base pressures of 10$^{-4}$ - 10$^{-3}$ Pa. A detailed structural analysis, by X-Ray Diffraction and Raman, allowed to assess the amorphous nature of the deposited films as well as to determine the base pressure that prevents boron oxide formation. In addition the crystallization dynamics has been characterized showing that film crystallinity already improves at relatively low temperatures (800 {\deg}C). Elastic properties of the boron films have been determined by Brillouin spectroscopy. Finally, micro-hardness tests have been used to explore cohesion and hardness of B films deposited on aluminum, silicon and alumina. The reported deposition strategy allows the growth of reliable boron coatings paving the way for their use in many technology fields., Comment: The research leading to these results has also received funding from the European Research Council Consolidator Grant ENSURE (ERC-2014-CoG No. 647554)

Abstract

Purpose: Although thyroid nodules are less common in the pediatric population, the risk of malignancy is higher than in adult patients. The aim of this study was to evaluate the ultrasonographic predictive factors of malignancy in thyroid nodules and to validate American College of Radiologists (ACR) TI-RADS performance in transition age patients. Methods: One hundred forty-two patients aged between 14 and 21 years referred to the participating centers for FNA biopsy of a thyroid nodule between 2007 and 2022 were included and ultrasound reports and sonographic images were retrospectively analyzed. Nodule features were defined according to the ACR-TIRADS lexicon. Two reference standards were applied: FNA cytology and surgical histology. The diagnostic performance of single sonographic features was estimated. Significant predictors were then included in a multivariate regression model. Results: Nodules included in ACR-TIRADS categories TR4 or TR5 had 10-fold increased risk of indeterminate or suspicious/malignant cytology [p < 0.001]. In univariate analysis, solid composition [p = 0.016] and presence of hyperechoic foci [p = 0.040] significantly increased the likelihood of malignant histology. In multivariate regression analysis, irregular margins [p = 0.011] and hyperechoic foci [p = 0.019] were independent predictors of indeterminate or suspicious/malignant cytology. Conclusion: Nodules included in ACR-TIRADS categories TR4 or TR5 had 10-fold increased risk of indeterminate or suspicious/malignant cytology in transition age. ACR-TIRADS was not able to rule-out malignancy compared to FNAB alone, suggesting the need to reconsider recommendations in the transition age group.

Abstract

Background:Tick-Borne Encephalitis virus (TBEV) is a positive-sense single-stranded RNA virus belonging to the Flaviviridae family. TBEV transmission typically occurs through infected Ixodes tick bite or by consumption of unpasteurised milk from infected cattle. Case report:We report the clinical, neuroimaging, electroencephalogram (EEG), and laboratory (microbiological tests and spinal tap) data of a 6- year-old boy with Tick-borne encephalitis. Our patient presented with a biphasic course, initially with a myositis-like picture on his first admission to the emergency department, and after a few days with an encephalitic picture, resulting in a second hospitalization. EEG showed focal slow activity, while his brain magnetic resonance imaging (MRI) showed a signal abnormality, which completely resolved on repeat MRI after 3 months. Conclusion:To our knowledge, this is the youngest patient presenting with myositis in the first phase of Tick-borne encephalitis (TBE). In the presence of a biphasic clinical course, with previous myositis, aspecific MRI changes in the thalamic and midbrain regions and an EEG documenting slowed bioelectrical activity should prompt suspicion of TBEV infection.

Abstract

OBJECTIVE: Percutaneous mitral valve repair with the MitraClip system is an alternative procedure for high-risk patients not suitable for conventional surgery. The MitraClip can be safely performed under general anesthesia (GA) or deep sedation (DS) with spontaneous breathing using a combination of propofol and remifentanil. This study aimed to evaluate the benefits of target-controlled infusion (TCI) of remifentanil and administration of propofol during DS compared with manual administration of total intravenous anesthesia (TIVA) medication during GA in patients undergoing MitraClip. We assessed the impact of these procedures in terms of remifentanil dose, hemodynamic profile, adverse events, and days of hospital stay after the process. PATIENTS AND METHODS: From March 2013 to June 2015 (mean age 73.5 ± 9,54), patients underwent transcatheter MitraClip repair, 27 received DS via TCI and 27 GA with TIVA. RESULTS: Acute procedural success was 100%. DS-TCI group, in addition to a significant reduction of remifentanil dose administrated (249 μg vs. 2865, p < 0.01), resulted in a decrease in vasopressor drugs requirement for hemodynamic adjustments (29.6% vs. 63%, p = 0.03) during the procedure and a reduction of hypotension (p = 0.08). The duration of postoperative hospitalization did not differ between the two groups (5.4 days vs. 5.8 days, p = 0.4). CONCLUSIONS: Administration of remifentanil by TCI for DS in spontaneously breathing patients offers stable anesthesia conditions, with a lower amount of drugs, higher hemodynamic stability, and decreased side effects.

OBJECTIVE: Spontaneous coronary artery dissection (SCAD) is a spontaneous separation of the coronary artery wall whose etiology appears to be poorly understood. SCAD is a rare cause of acute coronary syndromes, and it is a life-threatening condition. CASE REPORT: We report the case of a young woman who developed SCAD during a thyroid storm (TS). RESULTS: To the best of our knowledge, this is the first reported case of SCAD during a TS, and it suggests a possible association between high levels of circulating thyroid hormones and SCAD susceptibility. CONCLUSIONS: Early identification of SCAD predisposing factors is important to identify highrisk patients. In patients presenting to the emergency department because of chest pain with a history of dysthyroidism, early determination of thyroid hormones and troponin could prevent certain forms of sudden cardiac death.

Abstract

AbstractHardmetals are materials employed to produce cutting and forming tools as well as wear resistant parts. Standard powder metallurgy suffers limitations in the manufacturing of shapes required by application-oriented design. Therefore, there is interest for the implementation of additive manufacturing, in particular low temperature techniques as binder jetting because they allow to preserve microstructures and peculiar properties. In our work, the powder was tungsten carbide with 12 wt.% cobalt (WC-Co). Shaping by binder jetting was followed by curing treatment to promote the binder polymerization, vacuum sintering and sinter-HIP to achieve near-full density. The powder was analysed in terms of size and shape, to determine its suitability for the procedure. Then, the effects of different combinations of printing parameters, layer thickness (50–100 μm) and binder saturation (60/75/90%), on the density of the green bodies were analysed. Finally, the relative density of the sintered components was measured and the pores shape and size were studied by SEM imaging, to assess possible consequences of the deposition procedure. Vickers hardness along the samples cross-section was measured and correlated to the printing conditions employed.
