Holmquist-Johnson-Cook (HJC) constitutive model has been widely used in dynamic response analysis of concrete-like materials under impact and explosion. Based on the available data from uniaxial compression tests, triaxial compression tests, Brazilian splitting tests as well as SHPB experiments of 2400 m deep Jinping marble, a set of HJC model parameters suitable for high strength brittle marble were determined. Then, on the basis of one-dimensional static dynamic combined SHPB experiments, the numerical simulation of one-dimensional static dynamic combined SHPB experiments of Jinping marble were carried out by LS-DYNA software. Comparing the experimental and numerical simulation results, the rationality of the model parameters was verified. The numerical simulation results show that: from the perspective of stress-strain curve, the numerical simulation curve is consistent with the experimental curve, and the deviation of peak strength is less than 5%; from the perspective of damage evolution, the marble in the one-dimensional static and dynamic combined SHPB experiments are mainly tensile splitting failure. With the increase of prestress, the more serious the crack expansion and internal damage, the more broken the rock interior. Finally, the sensitivity of each parameter in the model is quantitatively calculated, and the high-sensitivity parameters are G, B, fc, Smax, μc and K1, which should be accurately obtained based on experiments.

Online reviews have become a valuable resource for decision making. In recent years, analysis ofreviews has attracted significant attention. Individuals and organizations in making purchase and other organizational decisions are increasingly using online reviews. Positive reviews acclaim significant financial gains, fame and prestige for businesses in market. On the other end, this gives strong enticement to fraudulent to hypocrite the system by posting disingenuous reviews to promote or to vilify some target products and services, which is known as opinion spam. Therefore, we made this research effort as an initial impetus in the direction to identify the presence of fake reviews. We performed this experiment on Wallet Apps accessible through Google Play Store. To do so, we rate applications based on features availability existence in Google App based on App content and user reactions. We computed four major scores-Description score, Positive Store, Negative Store and Review Tag Score and finally assigned a cumulative normalized score to all Wallet Apps. Further, a comparative analysis has been done between cumulative normalized score and stated Google App rating. Significant deviation indicates a strong probability that application has an opinion spam.

We report a novel glycan array architecture that binds the mannose-specific glycan binding protein, concanavalin A (ConA), with sub-femtomolar avidity. A new radical photopolymerization developed specifically for this application combines the grafted-from thiol–(meth)acrylate polymerization with thiol–ene chemistry to graft glycans to the growing polymer brushes. The propagation of the brushes was studied by carrying out this grafted-to/grafted-from radical photopolymerization (GTGFRP) at >400 different conditions using hypersurface photolithography, a printing strategy that substantially accelerates reaction discovery and optimization on surfaces. The effect of brush height and the grafting density of mannosides on the binding of ConA to the brushes was studied systematically, and we found that multivalent and cooperative binding account for the unprecedented sensitivity of the GTGFRP brushes. This study further demonstrates the ease with which new chemistry can be tailored for an application as a result of the advantages of hypersurface photolithography.

To investigate the impact of an electronic medical record management system (EMRMS) on disease activity and the frequency of outpatient visits among patients with ankylosing spondylitis (AS). We identified 652 patients with AS who were followed up for at least 1 year before and after the first Ankylosing Spondylitis Disease Activity Score (ASDAS) assessment and compared the number of outpatient visits and average visit time within 1 year before and after the initial ASDAS assessment. Finally, we analyzed 201 patients with AS who had complete data and received ≥ 3 continuous ASDAS assessments at an interval of 3 months, and we compared the results of the second and third ASDAS assessments with those of the first. The number of annual outpatient visits increased after ASDAS assessment (4.0 (4.0, 7.0) vs. 4.0 (4.0, 8.0), p < 0.001), particularly among those with a high initial disease activity. The average visit time was reduced within 1 year after ASDAS assessment (6.4 (8.5, 11.2) vs. 6.3 (8.3, 10.8) min, p = 0.073), especially among patients whose with an inactive disease activity was < 1.3 (ASDAS C-reactive protein (CRP) 6.7 (8.8, 11.1) vs. 6.1 (8.0, 10.3) min, p = 0.033;ASDAS erythrocyte sedimentation rate (ESR) 6.4 (8.7, 11.1) vs. 6.1 (8.1, 10.0) min, p = 0.027). Among patients who received at least three ASDAS assessments, the third ASDAS-CRP tended to be lower than the first (1.5 (0.9, 2.1) vs. 1.4 (0.8, 1.9), p = 0.058). The use of an EMRMS increased the frequency of ambulatory visits among AS patients with high and very high disease activity and reduced the visit time among those with an inactive disease. Continual ASDAS assessments may help control the disease activity of patients with AS. © 2023, The Author(s).

Isospin symmetry is a fundamental concept in nuclear physics. Even though isospin symmetry is partially broken, it holds approximately for most nuclear systems, which makes exceptions very interesting from the nuclear structure perspective. In this framework, it is expected that the spins and parities of the ground states of mirror nuclei should be the same, in particular for the simplest systems where a proton is exchanged with a neutron or vice versa. In this Letter, we present evidence that this assumption is broken in the mirror pair Br71 and Kr71 system. Our conclusions are based on a high-statistics β decay study of Kr71 and on state-of-the-art shell model calculations. In our work, we also found evidence of a new state in Se70, populated in the β-delayed proton emission process which can be interpreted as the long sought coexisting 0+ state.

Machine learning plays an important and growing role in molecular simulation. The newest version of the OpenMM molecular dynamics toolkit introduces new features to support the use of machine learning potentials. Arbitrary PyTorch models can be added to a simulation and used to compute forces and energy. A higher-level interface allows users to easily model their molecules of interest with general purpose, pretrained potential functions. A collection of optimized CUDA kernels and custom PyTorch operations greatly improves the speed of simulations. We demonstrate these features on simulations of cyclin-dependent kinase 8 (CDK8) and the green fluorescent protein (GFP) chromophore in water. Taken together, these features make it practical to use machine learning to improve the accuracy of simulations at only a modest increase in cost. Copyright © 2023, The Authors. All rights reserved.

Alzheimer's disease (AD) is the leading cause of dementia, presenting a significant unmet medical need worldwide. The pathogenesis of AD involves various pathophysiological events, including the accumulation of amyloid and tau, neuro-inflammation, and neuronal injury. Clinical trials focusing on new drugs for AD were documented in 2020, but subsequent developments have emerged since then. Notably, the US-FDA has approved Aducanumab and Lecanemab, both antibodies targeting amyloid, marking the end of a nearly two-decade period without new AD drugs. In this comprehensive report, we review all trials listed in ***, elucidating their underlying mechanisms and study designs. Ongoing clinical trials are investigating numerous promising new drugs for AD. The main trends in these trials involve pathophysiology-based, disease-modifying therapies and the recruitment of participants in earlier stages of the disease. These trends underscore the significance of conducting fundamental research on pathophysiology, prevention, and intervention prior to the occurrence of brain damage caused by AD.

BACKGROUND:Traumatic brain injury (TBI) continues to be a major cause of death and disability worldwide. Effective treatment options are limited, and randomized clinical data has been futile. OBJECTIVE:In this study, we assessed the efficacy of tauroursodeoxycholic acid (TUDCA) in treating TBI using a controlled cortical impact injury model in male Wistar rats. METHODS:Animals were randomized into two experimental groups: 1) TBI with sham treatment (Control, n = 12) and 2) TBI treated with intravenous infusion of 300 mg/kg TUDCA (TUDCA-treated group, n = 10) 30 min post-injury. Anxiety levels and magnetic resonance imaging studies were performed on days 1 and 7 post-injury. Animals were euthanized on day 7 for histopathological assessments. RESULTS:On days 1 and 7, we observed a smaller brain lesion volume in the TUDCA-treated group compared with the Control group and greater cytotoxic edema on day 1 in the Control group. Elevated plus maze revealed a lower anxiety index for the TUDCA-treated group on day 7. CONCLUSION:Our study showed that TBI rats treated with TUDCA at a hyperacute stage had a statistically significant reduction in lesion volume and improved levels of anxiety. However, a dose-response relationship and ideal therapeutic window still need to be determined. Future studies should consider a multiday therapy paradigm to identify the optimum intervention frequency in a mixed-gender.

Technologies like additive manufacturing, microfluidics, and electrospray show a possibility of generating a variety of 3-Dimensional structures but seriously suffer in adapting and utilizing the wide variety of available biocompatible materials because of innate diverse physical and chemical properties of biomaterials. It is very important to have a technology which can be viable and dynamically adaptable for different types of materials in generating uniform structures. This work presents a novel cell-laden hydrogel generation using the surface tension phenomenon in controlling the size of the hydrogel.
