Evaluating the use of wearables in the masseter and temporal muscles: a scoping review protocol

ABSTRACT Purpose: to develop a scoping review protocol that seeks to identify which procedures and for what purpose wearables available in the literature are being used on the masseter and temporal muscles. Methods: the approach recommended by The Joanna Briggs Institute and the PRISMA-P guidelines, will follow. Databases to be searched include PubMed, Cochrane Library, LILACS, Scopus, Web of Science, Embase and grey literature. In the first step, two reviewers will independently evaluate the articles by titles and abstracts, then, a full review of the selected articles will be performed according to the inclusion and exclusion criteria. Any uncertainties or differences of opinion will be discussed for consensus. Articles published without date or language restrictions will be included. All components will be presented in tables and flow charts. In addition, a narrative summary of each component will be included for further details. Final Considerations: this protocol will present the general state of the literature on the use of wearables in masseter and temporal masticatory muscles.
A unified modeling and trajectory planning method based on system manipulability for the operation process of the legged locomotion manipulation system

Abstract Flexibility is one of the most significant advantages of legged robots in unstructured environments. However, quadruped robots cannot interact with environments to complete some manipulation tasks. One effective way is to load a manipulation arm. In this paper, we exhibit a quadruped locomotion manipulation system (LMS) named HITPhanT. This system comprises a quadruped locomotion platform and a six-degree-of-freedom manipulation arm. Besides, when the LMS moves to a designated position for operation, it is necessary to constrain the foot contact points to avoid sliding. Therefore, the foot contact point is regarded as a spherical hinge. So the locomotion platform can be considered as a parallel mechanism. A hybrid kinematics model is established by considering the serial robotic arms connecting this parallel mechanism. Besides, the trajectory planning method, which improves the system’s manipulability in evaluating the system balance, is also proposed. Finally, corresponding experiments verify the overall system’s stabilization and algorithm’s effectiveness.
Study on Sintering Mechanism and Mechanical Properties of Nano-Cu based on Molecular Dynamics Simulation

Nano-metal materials sintering has received increasing attention in recent years for its promising performance in the wide bandgap semiconductor packaging. In this paper, molecular dynamics (MD) simulation method were applied to simulate the nano-Cu sintering mechanism and the subsequent mechanical behavior. Hybrid sintering, comprising nanosphere (NS) and nanoflake (NF), was carried out at temperatures ranging from 500K to 650K. Furthermore, shearing simulations were conducted with constant strain rates on the sintered structure at multiple temperatures, and subsequently correlated the extracted mechanical properties with the sintering behavior. The results indicated that the mechanical properties of nano-Cu sintered structure were improved by tuning material composition and increasing the sintering temperature. We established a relationship between the sintered microstructure and mechanical response, the shear modulus and shear strength of the sintered structure with NF particles increased to 41.2GPa and 3.51GPa respectively. It offers valuable insights into the preparation phase of nano Cu paste for sintering technology.
Adaption of Pseudomonas ogarae F113 to the Rhizosphere Environment—The AmrZ-FleQ Hub

Motility and biofilm formation are two crucial traits in the process of rhizosphere colonization by pseudomonads. The regulation of both traits requires a complex signaling network that is coordinated by the AmrZ-FleQ hub. In this review, we describe the role of this hub in the adaption to the rhizosphere. The study of the direct regulon of AmrZ and the phenotypic analyses of an amrZ mutant in Pseudomonas ogarae F113 has shown that this protein plays a crucial role in the regulation of several cellular functions, including motility, biofilm formation, iron homeostasis, and bis-(3′-5′)-cyclic dimeric guanosine monophosphate (c-di-GMP) turnover, controlling the synthesis of extracellular matrix components. On the other hand, FleQ is the master regulator of flagellar synthesis in P. ogarae F113 and other pseudomonads, but its implication in the regulation of multiple traits related with environmental adaption has been shown. Genomic scale studies (ChIP-Seq and RNA-Seq) have shown that in P. ogarae F113, AmrZ and FleQ are general transcription factors that regulate multiple traits. It has also been shown that there is a common regulon shared by the two transcription factors. Moreover, these studies have shown that AmrZ and FleQ form a regulatory hub that inversely regulate traits such as motility, extracellular matrix component production, and iron homeostasis. The messenger molecule c-di-GMP plays an essential role in this hub since its production is regulated by AmrZ and it is sensed by FleQ and required for its regulatory role. This regulatory hub is functional both in culture and in the rhizosphere, indicating that the AmrZ-FleQ hub is a main player of P. ogarae F113 adaption to the rhizosphere environment.
Decoupling electrical and thermal properties in antimony telluride based artificial multilayer for high thermoelectric performance

In this work, Sb2Te3/Poly(3,4-ethylenedioxythiophene)/Sb2Te3 sandwich structure was artificially fabricated. This leads to a simultaneous increase of electrical conductivity and decrease of thermal conductivity by tailoring electric flow along the more-electrically conductive parallel path and thermal flow blocked across the less-thermally conductive perpendicular direction. The maximum of thermoelectric figure of merit was increased by 116%, reaching 1.3 at 523 K.
Warm-Season Effects of the Gulf Stream on Mesoscale Characteristics of the Atmospheric Boundary Layer

Abstract The meteorological regime off the coast of North Carolina exhibits little synoptic-scale baroclinity during the summer months. As a result, the large-scale atmospheric forcing in this region is frequently weak. Given this weak synoptic forcing, mesoscale boundary layer circulations are dominant. One such circulation develops in response to the sea surface temperature discontinuity between the Gulf Stream and the relatively cooler water of the Continental Shelf. When synoptic conditions are favorable, differences in surface fluxes of heat and moisture across this discontinuity cause the development of an ageostrophic solenoidal circulation and the creation of an atmospheric boundary layer convergence zone. This resulting frontal zone, or Gulf Stream atmospheric front (GSAF), is a commonly observed feature in this region during the warm season. Simulations using The Pennsylvania State University–National Center for Atmospheric Research mesoscale model are combined with data gathered from the High-R.
Fault prediction algorithm of slow variable signal based on multidimensional data driving

With the increase of fault history data, the problem of high precision and long-time fault prediction under different failure modes is presented. We propose a multi-channel fusion fault prediction algorithm based on Long Short-Term Memory (LSTM) deep network. The prediction ability of the algorithm increases with the increase of training samples. Based on the analysis of the influence of different network parameters on the prediction accuracy, the optimal network parameters are selected to realize the long-time and high-precision fault prediction. It can recognize fault prediction without historical data. And it can integrate multi-channel information for off-line training to achieve the goal of self-increasing fault prediction ability.
Heuristics for Quantum Computing Dealing with 3-SAT

The SAT problem is maybe one of the most famous NP-complete problems. This paper deals with the 3-SAT problem. We follow a sort of incremental strategy to save computational costs with respect to the classical quantum computing approach. We present an heuristics that leads this strategy, improving the performance of the purely random incremental scheme. We finally validate our approach by means of a thorough empirical study.
Fruit Fly Optimization Technique Based Regulator for LFC of Conventional Power System with the Integration of Plugin Electric Vehicles

In this paper, a recent soft computing approach of fruit fly optimization technique (FFOT) based tilt-integral-derivative plus filter (TIDN) regulator is enforced to attain the frequency stabilization in the two-area conventional power system (TACPS). The TACPS integrates the Hydro-thermal units in each area and carried out the dynamical analysis for 10% step load disturbance (SLD) in area-1. The supremacy of the adopted FFOT is demonstrated with other approaches of moth flame optimization (MFO) and flower pollination algorithm (FPA). The TACPS is considered with the communication time delays (CTDs) as the realistic constraint to conduct the system dynamic analysis close to practical nature. Further, the TACPS is integrated with the plugin electric vehicles (PEVs) in area-1 to attain the enhancement in system dynamic performance.
IAFDroid: Demystifying Collusion Attacks in Android Ecosystem via Precise Inter-App Analysis

Inter-app communication mechanism allows app developers to improve Android apps’ usability and provide users with rich functions via interacting with exposed components or performing data sharing. However, this mechanism may be leveraged by malicious developers or unintentionally misused by inexperienced developers. For end users, this type of attack may cause privacy breaches or remote controls of personal phone, which have a great threat of the user’s data security. The key to analyzing whether there is a collusion attack is to analyze the existence of communication channels between apps. The existing static analysis tools have done some work in this area, but the comprehensiveness of the analysis is insufficient, and such research lacks a unified test standard. In this paper, we present collusion attacks using more concealed inter-app communication channels, which can bypass existing security detection mechanisms. To defend against the new attacks, we design IAFDroid, an analysis framework that combines static and taint analysis. By examining 20K real-world apps, IAFDroid found that 94.4% of the most exposed components of Android may be leveraged to perform collusion attacks. Furthermore, the evaluation showed that the feature set extracted by IAFDroid could be used to promote the accuracy of Android malware detection. We contribute a more comprehensive benchmark for IAC analysis, IACBench, which includes the new attacks we propose. To facilitate follow-up studies, we open-sourced IAFDroid and IACBench based on the GPL agreement.
Precedence of Bone Loss Accompanied with Changes in Body Composition and Body Fat Distribution in Patients with Type 2 Diabetes Mellitus

Methods A total of 596 patients with T2DM, including 308 male and 288 female patients, were included in the follow-up study; the median follow-up time was 2.17 years. We calculated the difference between the endpoint and the baseline of each body composition index and the annual rate. The research participants were divided into the increased body mass index (BMI) group, stable BMI group, and decreased BMI group. Some confounding factors were adjusted, such as BMI, fat mass index (FMI), muscle mass index (MMI), muscle/fat mass ratio (M/F), trunk fat mass index (TFMI), appendicular skeletal muscle mass index (ASMI), and appendicular skeletal muscle mass/trunk fat mass ratio (A/T). Results The linear analysis showed that ΔFMI and ΔTFMI were negatively correlated with the change in femoral neck BMD (ΔFNBMD) and ΔMMI, ΔASMI, ΔM/F, and ΔA/T were positively correlated with ΔFNBMD. The risk of FNBMD reduction in patients with increased BMI was 56.0% lower than that in patients with decreased BMI; also, the risk in patients with stable M/F was 57.7% lower than that in patients with decreased M/F. The risk in the A/T increase group was 62.9% lower than that in the A/T decrease group. Conclusions A reasonable muscle/fat ratio is still beneficial to maintaining bone mass. Maintaining a certain BMI value is conducive to maintaining FNBMD. Simultaneously, increasing the proportion of muscle mass and reducing fat accumulation can also prevent FNBMD loss.
Hyperparameter-Optimization-Inspired Long Short-Term Memory Network for Air Quality Grade Prediction

In the world, with the continuous development of modern society and the acceleration of urbanization, the problem of air pollution is becoming increasingly salient. Methods for predicting the air quality grade and determining the necessary governance are at present most urgent problems waiting to be solved by human beings. In recent years, more and more machine-learning-based methods have been used to solve the air quality prediction problem. However, the uncertainty of environmental changes and the difficulty of precisely predicting quantitative values seriously influence prediction results. In this paper, the proposed air pollutant quality grade prediction method based on a hyperparameter-optimization-inspired long short-term memory (LSTM) network provides two advantages. Firstly, the definition of air quality grade is introduced in the air quality prediction task, which turns a fitting problem into a classification problem and makes the complex problem simple; secondly, the hunter–prey optimization algorithm is used to optimize the hyperparameters of the LSTM structure to obtain the optimal network structure adaptively determined through the use of input data, which can include more generalization abilities. The experimental results from three real Xi’an air quality datasets display the effectiveness of the proposed method.
Living Cells and Cell-Derived Vesicles: A Trojan Horse Technique for Brain Delivery

Brain diseases remain a significant global healthcare burden. Conventional pharmacological therapy for brain diseases encounters huge challenges because of the blood–brain barrier (BBB) limiting the delivery of therapeutics into the brain parenchyma. To address this issue, researchers have explored various types of drug delivery systems. Cells and cell derivatives have attracted increasing interest as “Trojan horse” delivery systems for brain diseases, owing to their superior biocompatibility, low immunogenicity, and BBB penetration properties. This review provided an overview of recent advancements in cell- and cell-derivative-based delivery systems for the diagnosis and treatment of brain diseases. Additionally, it discussed the challenges and potential solutions for clinical translation.
The Past and Present of Crime Research in Social Forces: How the Sociology of Crime Lost its Roots—And Found Them Again

Abstract:The centennial of Social Forces provides an opportunity to examine change and stability in crime research in one of sociology's oldest journals. Since the first issue of Social Forces in 1922, crime and punishment have transitioned from marginal topics subsumed under the umbrella of deviance studies to a central research area. This essay traces the intellectual development of crime research as captured in Social Forces' pages and contrasts it with the growing independence of criminology as an academic field. To do so, I employ two analyses. First, I examine the topical classifications provided by Moody, Edelmann and Light (2022). Second, I expand upon these classifications by using structural topic models (STM) to detect clusters of crime research activity in Social Forces' abstracts and group them into "eras" of crime research. The analysis reveals a circular development of crime research in Social Forces that reflects broader trends in the sociology of crime. Themes of power, stratification, and punishment oriented early studies on crime. Research attention focused on inequality within the justice system, the effects of juvenile justice contact on criminal labeling and recidivism, and inequalities resulting from justice system contact. However, as crime rates rose throughout the Western world, Social Forces articles sought to explain the causes of crime and evaluate policies designed to cull the crime wave. In recent decades, persistent crime declines combined with growing concern with an oversized prison system have refocused attention on incarceration and its collateral consequences, especially for adolescent well-being and racial and class inequalities. In this way, crime research in Social Forces has returned to core themes of power and stratification that motivated early work in the sociology of crime. It has also distanced itself from individual etiology and policy studies that once dominated the journal's pages and that continue to appear in specialist outlets.
Biaxiality of cholesteric phases in rod-like polymer solutions

A mean field theory for the biaxiality of a cholesteric phase in rod-like polymer solutions is presented. By taking into account both excluded volume and attractive interactions between rods, we calculate the biaxiality of the cholesteric phase as a function of temperature and concentration. At low concentrations of rods, the biaxiality increases with increasing temperature. At high concentrations above , the biaxiality becomes the maximum as a function of temperature. We also calculate phase diagrams on the temperature–concentration plane and study phase separations between an isotropic phase and a biaxial cholesteric phase.
The Coexistence Between Probable Sarcopenia, Undernutrition and Frailty in Geriatric Outpatients

Objective: Sarcopenia, undernutrition and frailty are three interrelated geriatric problems with strong associations with mortality and morbidity. This study assesses coexistence of probable sarcopenia, undernutrition and frailty in patients admitted to outpatient clinics in our country. Materials and Methods: The study population consisted of participants over the age of 60 years who applied to the geriatric outpatient clinics of a university hospital between December 2012 and August 2021. All of the participants were screened for frailty using the FRAIL scale, while the mini nutritional assessment-short form was used for undernutrition screening. Hand grip strength was measured using a Jamar hydraulic hand dynamometer, based on the European Working Group on Sarcopenia in Older People definition regional cut-offs (<35 kg <20 kg in males and females, respectively). Results: Included in the study were 438 participants with a mean age of 74+6.7, 129 of whom were male (29.5%). The prevalence of three clinical conditions (probable sarcopenia, undernutrition and frailty) was 48.8% (214), 24.2% (106) and 65.1% (285), respectively. Both probable sarcopenia and undernutrition were detected in 15.5% (68%), and 13.6% (60) of the sample had all three conditions. Conclusion: The majority of patients in the study were either frail (65.1%), probable sarcopenic (48.8%) or undernourished (24.2%), and the coexistence of all three clinical conditions was significant, affecting 13.6% of the total (60). Our study is the first to investigate the overlaps of the three interrelated geriatric syndromes in patients who applied to geriatric outpatient clinics.
Mechanisms of Action of the Host-Targeting Agent Cyclosporin A and Direct-Acting Antiviral Agents against Hepatitis C Virus

Several direct-acting antivirals (DAAs) are available, providing interferon-free strategies for a hepatitis C cure. In contrast to DAAs, host-targeting agents (HTAs) interfere with host cellular factors that are essential in the viral replication cycle; as host genes, they are less likely to rapidly mutate under drug pressure, thus potentially exhibiting a high barrier to resistance, in addition to distinct mechanisms of action. We compared the effects of cyclosporin A (CsA), a HTA that targets cyclophilin A (CypA), to DAAs, including inhibitors of nonstructural protein 5A (NS5A), NS3/4A, and NS5B, in Huh7.5. 1 cells. Our data show that CsA suppressed HCV infection as rapidly as the fastest-acting DAAs. CsA and inhibitors of NS5A and NS3/4A, but not of NS5B, suppressed the production and release of infectious HCV particles. Intriguingly, while CsA rapidly suppressed infectious extracellular virus levels, it had no significant effect on the intracellular infectious virus, suggesting that, unlike the DAAs tested here, it may block a post-assembly step in the viral replication cycle. Hence, our findings shed light on the biological processes involved in HCV replication and the role of CypA.
Detecting Objectionable Videos

This paper addresses the problem of detecting objectionable videos, which has never been carefully studied before. Our method can be efficiently used to filter objectionable videos on Internet. One tensor based key-frame selection algorithm, one cube based color model and one objectionable video estimation algorithm are presented. The key frame selection is based on motion analysis using the three-dimensional structure tensor. Then the cube based color model is employed to detect skin color in each key frame. Finally, the video estimation algorithm is applied to estimate objectionable degree in videos. Experimental results on a variety of real-world videos downloaded from Internet show that this method is promising.
Systematic Investigation on Supported Gold Catalysts Prepared by Fluorine-Free Basic Etching Ti3AlC2 in Selective Oxidation of Aromatic Alcohols to Aldehydes

Conventional methods to prepare supported metal catalysts are chemical reduction and wet impregnation. This study developed and systematically investigated a novel reduction method based on simultaneous Ti3AlC2 fluorine-free etching and metal deposition to prepare gold catalysts. The new series of Aupre/Ti3AlxC2Ty catalysts were characterized by XRD, XPS, TEM, and SEM and were tested in the selective oxidation of representative aromatic alcohols to aldehydes. The catalytic results demonstrate the effectiveness of the preparation method and better catalytic performances of Aupre/Ti3AlxC2Ty, compared with those of catalysts prepared by traditional methods. Moreover, this work presents a comprehensive study on the influence of calcination in air, H2, and Ar, and we found that the catalyst of Aupre/Ti3AlxC2Ty-Air600 obtained by calcination in air at 600 °C performed the best, owing to the synergistic effect between tiny surface TiO2 species and Au NPs. The tests of reusability and hot filtration confirmed the catalyst stability.
