Relative contribution of neuromuscular activation, muscle size, and muscle quality to maximum strength output of the thigh muscles in young individuals
Authors: Yoshiko Akito , Watanabe Kohei , Akima Hiroshi 
Published: January 2023

AbstractThis study aimed to investigate the relationship between maximal muscle strength and neuromuscular activation, muscle size, and quality of quadriceps (QF) and hamstring muscles (HM). The study included 24 young men and women. The neuromuscular activation parameter was recorded using a single‐channel surface electromyography (EMG) with the root mean square (RMS) during maximal isometric knee extension and flexion from four muscles: rectus femoris and vastus lateralis for QF; biceps femoris and semitendinosus for HM. In addition, the peak torque was measured during the same session. B‐mode ultrasonographic transverse images were obtained from the anterior, lateral, and posterior thighs. Furthermore, we calculated the muscle thickness (MT) and echo intensity (EI) of the four muscles as indicators of muscle size and quality. The averaged MT, EI, and absolute RMS of QF were calculated by averaging the values of the rectus femoris and vastus lateralis, and that of HM was calculated by averaging the values of the biceps femoris and semitendinosus. The knee extension peak torque was correlated with EI (r = −0.61, P < 0.01) and RMS (r = 0.53, P < 0.01) in the QF. In contrast, the knee flexion peak torque was correlated with RMS (r = 0.53, P < 0.05) but not with MT and EI in HM. In addition, EI and RMS in QF, and RMS in HM were selected as the major determinants of muscle strength in the stepwise regression analysis. These results suggest that muscle strength is moderately associated with different factors related to the thigh muscles in young individuals.
Modelling of a piezoelectric beam with a full-bridge rectifier under arbitrary excitation: experimental validation
Authors: Febbo Mariano , Machado Sebastian P. , Oliva Alejandro , Ortiz Matias , Pereyra Nicolas 
Published: January 2023

Abstract
This paper presents a set of nonlinear differential equations to model a piezoelectric energy harvesting (PEH) system with a full-bridge waveform rectifier (FWR) under arbitrary base excitations. The PEH comprises a piezoelectric element modeled as a current source with a capacitor in parallel, which are connected with an inductor and a resistor. The inductor is proposed to smooth the current generated by the piezoelectric element under rapid mechanical variations and improve the convergence of the set of differential equations. The equations are obtained using piecewise linear modelling for the diodes. The main advantage of this piecewise linear modelling is considering different bias points to represent the nonlinear characteristics of real diodes. Numerical simulations are employed to obtain the optimum inductor value through a comparison with an analytical result, validated with experimental tests. A real case of random acceleration in a bike is applied to the PEH-FWR to evaluate the performance of the proposed equations. They are validated with experiments, a LTspice formulation and a numerical previous one. The proposed formulation can estimate the output DC voltage and energy for a large range of excitation frequencies, including resonant and nonresonant conditions and arbitrary or harmonically externally excited PEHs with FWR.

ABSTRACT
This study aimed to analyze the time under tension (TUT) behavior in the bench press exercise performance in recreationally trained individuals. A systematic review was performed based on the PRISMA recommendations and registered on PROSPERO (CRD42022301830). MEDLINE (PubMed), Scopus, SPORTDiscus, and Lilacs (BVS) databases were consulted with the terms (resistance training [Title/Abstract]) OR (strength training [Title/Abstract]) AND (time under tension [Title/Abstract]). Cohort studies that analyzed the TUT in the bench press exercise in individuals with experience in resistance training were included. We used the Critical Appraisal Skills Program tool to analyze the methodological quality of the included studies. Thirteen studies met the inclusion criteria. The total number of participants was 215 individuals (179 men and 36 women). TUT was analyzed from the manipulation of each study variable. The behavior of the TUT in the bench press exercise varies according to the training protocol and method used. The TUT and the number of repetitions can vary to quantify the training volume.
Theology and Mathematics in Plato’s Later Ethics
Authors: Bartninkas Vilius 
Published: January 2023

In Plato’s later ethics, the key challenge to one’s personal progress is unorderly thoughts and motions of soul. This disorder should be corrected by recognising and repeating the orderly thoughts and motions of cosmic gods. This paper examines the theoretical assumptions of Plato’s later ethics. A closer analysis of the Timaeus reveals a peculiar conception of mathematics, according to which numbers and their relations not only reveal facts about the reality, but also express values and ideals. By learning mathematics human beings come to know the everyday ethical life of cosmic gods and become like them.
Loci as Subject of Derision: Between Cicero’s Rhetorical Theory and Practice
Authors: Kučinskienė Audronė 
Published: January 2023

There is no doubt that commonplaces, so called topoi, or loci, played a very important role both in the ancient rhetorical theory and in practice. They conform to the main part of invention in the rhetorical treatises, such as Rhetorica ad Herennium, Cicero’s De Inventione, Topica etc., and they enable an orator to develop his argument in any desirable direction (in utramque partem), and sometimes become the main tool of rhetorical strategy. In his Orator, Cicero claims, that an accomplished speaker, whom he tries to delineate as an ideal, will be perfectly familiar with commonplaces and be able to treat them critically and manipulate according to his purposes. In this paper, on the ground Cicero’s Verrine speeches, I shall analyze how the orator predicts his opponents’ topoi and presents them in a different light, and by criticizing or even by mocking them, he diminishes them in order to strengthen his own arguments. In some cases, e.g. in the Fifth Book of the Actio secunda in Verrem (Verr. 2.5), this becomes the main strategy of speech, and corresponds to the methods delineated in the Orator 49.

Published: January 2023

AbstractTricalcium phosphates (TCPs) are of great interest in dental tissue engineering applications. The objective of this study was to incorporate magnesium (Mg) at different concentrations of 0.25, 0.50, 1.00, 2.50, and 5.00 wt.% to TCP and evaluate the effects on phase composition, density, and in vitro interaction with human dental pulp stem cells (hDPSCs). Our results showed that adding Mg stabilized the β-TCP crystal structure and increased the density of the TCP. Mg addition had no adverse effect on hPDSCs response. Although cellular proliferation was slightly less on Mg-TCPs at early time points, it increased significantly with time and in a dose-dependent manner. A similar trend was observed for cellular differentiation. Together, these data show for the first time that Mg addition at concentrations less than 2.50% (preferably at 1.00 or 2.50 wt.%) can be added safely to TCP for enhanced proliferation and differentiation of hDPSCs.

ABSTRACTThe Mw 7.2 Nippes, Haiti, earthquake occurred on 14 August 2021 in Haiti’s southwest peninsula and in the midst of significant social, economic, and political crises. A hybrid reconnaissance mission (i.e., combined remote and field investigation) was coordinated to document damage to the built environment after the event. This article evaluates two ground-motion records available in Haiti in the context of the geology of the region and known areas with significant damage, such as Les Cayes. We also present a new map of time-averaged shear-wave velocity values to 30 m depth (VS30) for Les Cayes and Port-au-Prince based on the geostatistical approach of kriging and accounting for region-specific geology proxies and field measurements of VS30. Case studies of ground failure observations, including landslides and liquefaction triggering, are described as well as the intersection of social and engineering observations. Maps depicting this important intersection are provided to facilitate the assessment of how natural hazards and social conflicts have influenced the vulnerability of Haiti’s population to earthquakes.

Authors: Sarani Esmaeil , Hataminejad Maryam , Azizi Hakim 
Published: January 2023

Background and Aims: Toxocariasis is a zoonotic parasitic disease with worldwide distribution caused by the larval stage of ascaridoid nematodes of dogs (Toxocara canis) and cats (Toxocara cati). The study was accomplished to determine the sequence variation in ITS2 and COX1 genes within isolates of Toxocara canis.
Materials and Methods: Two hundred Stool samples were collected randomly from dogs in public parks and streets from different regions of Zabol. Thirty samples containing eggs were isolated from the feces using Formalin ether 10% and centrifugal flotation. Genomic DNA was extracted, and COX1 and ITS2 were amplified by PCR-RFLP and sequenced. Sequence data were aligned using the BioEdit software and BLAST program and compared with published sequences in GenBank. The phylogenetic relationship between isolates of T. canis from Zabol city with other regions based on sequences obtained from COX1 and ITS2 genes and using MEGA7.0 software was investigated.
Results: For all samples, amplicons of about 388 and 422 base pairs were produced by PCR for ITS2 and COX1, respectively. Drawing the phylogenic tree of ITS2 and COX1 sequences of isolates of T. canis showed that the identified genotypes are not only different from each other but also from other parts of the world.
Conclusions: Our result showed that genetic variation among isolates of T. canis from Zabol is very low. For a deeper understanding of genetic diversity among populations of Toxocara, it is recommended to analyze more isolates from various geographical areas and variable genetic markers.

Published: January 2023

Mobile phones have become an integral part of our lives in the last two decades, leaving a digital trace of our activities and communication. This study aims to develop a data processing framework to evaluate human mobility and socioeconomic status based on call detail records. The methodology proposed first calculates radius of gyration and entropy for each user, then estimates the socioeconomic status by the price and age of the subscribers' phones. Finally, an unsupervised machine learning algorithm was used to group the cells into clusters based on their mobility and socioeconomic metrics.
The research showed differences between Buda and Pest during a large scale social event using mobile phone ages and prices. Additionally, the clustering results revealed homogenous groups of cells around Budapest, with similar mobility and socioeconomic metrics. The main conclusion is that mobile network data combined with mobile phone properties offer a useful tool for characterising urban mobility and socioeconomic status.

Background:
Quantitative regional assessment of thoracic function would enable clinicians to better understand the regional effects of therapy and the degree of deviation from normality in patients with thoracic insufficiency syndrome (TIS). The purpose of this study was to determine the regional functional effects of surgical treatment in TIS via quantitative dynamic magnetic resonance imaging (MRI) in comparison with healthy children.

Methods:
Volumetric parameters were derived via 129 dynamic MRI scans from 51 normal children (November 2017 to March 2019) and 39 patients with TIS (preoperatively and postoperatively, July 2009 to May 2018) for the left and right lungs, the left and right hemi-diaphragms, and the left and right hemi-chest walls during tidal breathing. Paired t testing was performed to compare the parameters from patients with TIS preoperatively and postoperatively. Mahalanobis distances between parameters of patients with TIS and age-matched normal children were assessed to evaluate the closeness of patient lung function to normality. Linear regression functions were utilized to estimate volume deviations of patients with TIS from normality, taking into account the growth of the subjects.

Results:
The mean Mahalanobis distances for the right hemi-diaphragm tidal volume (RDtv) were −1.32 ± 1.04 preoperatively and −0.05 ± 1.11 postoperatively (p = 0.001). Similarly, the mean Mahalanobis distances for the right lung tidal volume (RLtv) were −1.12 ± 1.04 preoperatively and −0.10 ± 1.26 postoperatively (p = 0.01). The mean Mahalanobis distances for the ratio of bilateral hemi-diaphragm tidal volume to bilateral lung tidal volume (BDtv/BLtv) were −1.68 ± 1.21 preoperatively and −0.04 ± 1.10 postoperatively (p = 0.003). Mahalanobis distances decreased after treatment, suggesting reduced deviations from normality. Regression results showed that all volumes and tidal volumes significantly increased after treatment (p < 0.001), and the tidal volume increases were significantly greater than those expected from normal growth for RDtv, RLtv, BDtv, and BLtv (p < 0.05).

Conclusions:
Postoperative tidal volumes of bilateral lungs and bilateral hemi-diaphragms of patients with TIS came closer to those of normal children, indicating positive treatment effects from the surgical procedure. Quantitative dynamic MRI facilitates the assessment of regional effects of a surgical procedure to treat TIS.

Opera co-creation: from collaborative translation to artistic co-creation in audiovisual translation and accessibility
Authors: Matamala Anna , Orero Pilar 
Published: January 2023

Research on collaborative translation has expanded in recent years, with a variety of terms such as community or volunteer translation being used to refer to these practices. This article focuses on the Traction project as an instance of artistic co-creation between professionals and non-professionals in opera, and it suggests that the Traction approach could be usefully utilised in the context of audiovisual translation and media accessibility. After an introduction to the challenges of 21st century opera and their quest for new audiences, the article discusses the concept of artistic co-creation. It also presents how opera co-creation is being assessed in Traction. The co-creation process and its evaluation are then related to translation and accessibility to propose artistic co-creation as a new approach to collaborative practices which can benefit both professionals and non-professionals.

Energy Efficient Multi-criterion Binary Grey Wolf Optimizer based Clustering for Heterogeneous Wireless Sensor Networks
Authors: Pal Raju , Saraswat Mukesh , Poonia Sandeep , Nayyar Anand , Rajput Pushpendra Kumar 
Published: January 2023

Abstract
Wireless sensor network has several constraints. The major constraint is the limited energy resource of the sensor nodes, limiting the overall efficiency and lifetime of the network system. Clustering is a widely used strategy that arranges the network into smaller groups called clusters for improving the performance and longevity of the network. The majority of swarm-based clustering algorithms focus on a single objective for optimization to find optimal cluster centers. However, in many practical situations, there is a need for simultaneous optimization of many objectives to get the promising cluster centers. Here, a multi-objective binary Grey wolf optimizer is used for finding Pareto optimal clustering centers to achieve five objectives, namely maximize overall CH energy, minimize compactness, minimize CH count, minimize energy from nonCH to CH transmission, and maximize separation. The stability period of the network with proposed approach is increased by 56%. Moreover simulation outcomes show the improved performance of the proposed method in terms of total residual energy, number of elected cluster heads, and network lifetime as compared to other state-of-the-art evolutionary clustering protocols such as SEP, IHCR, ERP, and BEECP.
Using Machine Learning Models for Predicting Culex Mosquito Habitats and Breeding Patterns in Washington D.C.

Published: January 2023

Abstract
Culex mosquitoes pose a significant threat to humans and other species due to their ability to carry deadly viruses such as the West Nile and Zika. Washington D.C., in particular, has a humid subtropical climate that makes it ideal as a habitat for mosquito breeding. Thus, tracking mosquitoes’ habitats and breeding patterns in Washington D.C. is crucial for addressing local public health concerns. Although fieldwork techniques have improved over the years, monitoring and analyzing mosquitoes is still difficult, dangerous, and time-consuming. In this work, we propose a solution by creating a Culex mosquito abundance predictor using machine learning techniques to determine under which conditions Culex mosquitoes thrive and reproduce. We used four environmental variables to conduct this experiment: precipitation, specific humidity, enhanced vegetation index (EVI), and surface skin temperature. We obtained sample data of these variables in the Washington D.C. areas from the NASA Giovanni Earth Science Data system, as well as mosquito abundance data collected by the D.C. government. Using these data, we created and compared four machine learning regression models: Random Forest, Decision Tree, Support Vector Machine, and Multi-Layer Perceptron. We searched for the optimal configurations for each model to get the best fitting possible. Random Forest Regressor produced the most accurate prediction of mosquito abundance in an area with the four environment variables, achieving a mean average error of 3.3. EVI was the most significant factor in determining mosquito abundance. Models and findings from this research can be utilized by public health programs for mosquito-related disease observations and predictions.
