In ultrasound elastography, plane-wave acquisitions and angular displacement compounding (ADC) are often used and combined to allow high frame rates and to improve accuracy of lateral displacement estimates, respectively. This study investigates the performance of displacement and strain estimation for ADC as a function of; the main-to-grating-lobe-amplitude ratio which decreases as a function of steering angle; plane-wave acquisition and Delay-and-Sum (DaS)-related parameters; and grating-lobe filter cut-off frequency. Three experiments were conducted with a block phantom to test ADC performance for displacement fields of varying complexity a lateral transducer shift, phantom rotation and phantom deformation. Experiments were repeated for four linear array transducers (pitch-to-lambda ratios between 0.6 and 1.4). Best ADC performance was found for steering angles that resulted in a theoretically derived main-to-grating-lobe-amplitude ratio of 1.7 dB for pure lateral translation and 6 dB for predominately latignificant compared to non-ADC (p=0.003) and literature (p=0.002). © 2020 Institute of Physics and Engineering in Medicine.Metal sulfides are emerging as an important class of materials for photocatalytic applications, because of their high photo responsive nature in the wide visible light range. In this class of materials, CdS with a direct band gap of 2.4 eV, has gained special attention due to the relative position of its conduction band minimum, which is very close to the energies of the reduced protons. However, the photogenerated holes in the valence band of CdS are prone to oxidation and destroy its structure during photocatalysis. Thus constructing a CdS based heterostructure would be an effective strategy for improving the photocatalytic performance. In this work we have done a detail theoretical investigation based on hybrid density functional theory calculation to get insight into the energy band structure, mobility and charge transfer across the CdS/CdSe heterojunction. The results indicate that CdS/CdSe forms type-II heterostructure that has several advantages in improving the photocatalytic efficiency under visible light irradiation. © 2020 IOP Publishing Ltd.Multiple-color emissive carbon dots (C-dots) are getting increasing attention in various fields. Herein, we report a facile solvothermal method for the synthesis of multiple-color emissive C-dots towards white-light emission. Under single ultraviolet-light excitation, three C-dots emit a well-controllable fluorescence emission wavelength at 440 nm, 500 nm and 610 nm by using different three amines (either ammonium hydroxide, ethylenediamine or p-phenylenediamine, respectively) and pyromellitic dianhydride as molecular precursors while another three C-dots emit a well-controllable fluorescence emission wavelength at 500 nm, 550 nm and 585 nm by using same three amines and naphthalene-1,4,5,8-tetracarboxylic dianhydride as molecular precursors. The maximum fluorescence wavelength of these C-dots is red-shifted by changing three different amines molecular precursor from ammonium hydroxide, ethylenediamine, to p-phenylenediamine. https://www.selleckchem.com/products/Nolvadex.html Furthermore, these C-dots have shown promising applications in the fields of white-light-emitting diodes devices and color printing. © 2020 IOP Publishing Ltd.Clinical Scenario Concussions are severely underreported, with only 47.3% of high school athletes reporting their concussion. The belief was that athletes who were better educated on the signs and symptoms and potential dangers of concussion would be more likely to report. However, literature has shown inconsistent evidence on the efficacy of concussion education, improving reporting behaviors. Factors such as an athlete's attitude, subjective norms, and perceived behavioral control have shown promise in predicting intention to report concussions in athletes. Focused Clinical Question Do attitudes, subjective norms, and perceived behavioral control influence adolescent athletes' intention to report? Summary of Key Findings Three studies (1 randomized control and 2 cross-sectional surveys) were included. Across the 3 studies, attitudes, subjective norms, and perceived behavioral control positively influenced athletes' reporting intention. The studies found that attitude toward concussion reporting and perceived behavioral control were the most influential predictors of reporting intention. Clinical Bottom Line There is moderate evidence to suggest that positive attitudes, supportive subjective norms, and increased perceived behavioral control influence reporting intention in secondary school athletes. Strength of Recommendation Grade B evidence exists that positive attitudes, supportive subjective norms, and increased perceived behavioral control positively influence concussion reporting intention in secondary school athletes.Very little is known about how long-term (>6 months) adaptation to a low-carbohydrate, high-fat (LCHF) diet affects insulin signaling in healthy, well-trained individuals. This study compared glucose tolerance; skeletal muscle glucose transporter 4 (GLUT4) and insulin receptor substrate 1 (IRS1) content; and muscle enzyme activities representative of the main energy pathways (3-hydroxyacetyl-CoA dehydrogenase, creatine kinase, citrate synthase, lactate dehydrogenase, phosphofructokinase, phosphorylase) in trained cyclists who followed either a long-term LCHF or a mixed-macronutrient (Mixed) diet. On separate days, a 2-hr oral glucose tolerance test was conducted, and muscle samples were obtained from the vastus lateralis of fasted participants. The LCHF group had reduced glucose tolerance compared with the Mixed group, as plasma glucose concentrations were significantly higher throughout the oral glucose tolerance test and serum insulin concentrations peaked later (LCHF, 60 min; Mixed, 30 min). Whole-body insulin sensitivity was not statistically significantly different between groups (Matsuda index LCHF, 8.7 ± 3.4 vs. Mixed, 12.9 ± 4.6; p = .08). GLUT4 (LCHF 1.13 ± 0.24; Mixed 1.44 ± 0.16; p = .026) and IRS1 (LCHF 0.25 ± 0.13; Mixed 0.46 ± 0.09; p = .016) protein content was lower in LCHF muscle, but enzyme activities were not different. We conclude that well-trained cyclists habituated to an LCHF diet had reduced glucose tolerance compared with matched controls on a mixed diet. Lower skeletal muscle GLUT4 and IRS1 contents may partially explain this finding. This could possibly reflect an adaptation to reduced habitual glucose availability rather than the development of a pathological insulin resistance.
