Evaluation of Lower-Limb Kinematics during Timed Up and Go (TUG) Test in Subjects with Locomotive Syndrome (LS) Using Wearable Gait Sensors (H-Gait System)

Few studies have dealt with lower-limb kinematics during the timed up and go (TUG) test in subjects with locomotive syndrome (LS). This study aimed to evaluate the characteristics of lower-limb kinematics during the TUG test in subjects with LS using the wearable sensor-based H-Gait system. A total of 140 participants were divided into the non-LS (n = 28), the LS-stage 1 (n = 78), and LS-stage 2 (n = 34) groups based on the LS risk test. Compared with the non-LS group, the LS-stage 1 and LS-stage 2 groups showed significantly smaller angular velocity of hip and knee extension during the sit-to-stand phase. The LS-stage 2 group showed significantly smaller peak angles of hip extension and flexion during the walking-out phase compared to the non-LS group. These findings indicate that the evaluation of the lower-limb kinematics during the TUG test using the H-Gait system is highly sensitive to detect LS, compared with the evaluation of the lower-limb kinematics when simply walking.
A three-dimensional radiative transfer model to interpret ranging scatterometer measurements from a pine forest

Abstract This paper addresses the propagation of microwaves in forested media. It interprets the vertical distribution of backscatter acquired by a ranging scatterometer in a pine forest at X band (9.5 GHz) and vertical incidence by means of modelling. A plane parallel radiative transfer model for the forest canopy exhibits a large discrepancy between the measured and estimated distribution. This is attributed to failure to represent the horizontal heterogeneity in the forest. Taking into account the height variability of the trees significantly improves the estimated distribution at the top of the canopy but the backscatter from the lower layers and the ground is still underestimated. To deal with this, a fully three-dimensional (3D) radiative transfer model is developed. By modelling precisely the propagation of the wave through the medium, the 3D approach allows accurate estimation of the ground backscatter and slightly improves the estimated backscatter from the lower layers. It is demonstrated that 3D modelling is required to estimate accurately the vertical distribution of backscatter, total backscatter and the height of the centre of backscatter in the experimental data. These results have implications for the interpretation of more general measurements scenarios, especially as regards forest height measurement by radar interferometry.
Ergodic optimization for generic continuous functions

Given a real-valued continuous function $f$ defined on the phase space of a dynamical system, an invariant measure is said to be maximizing if it maximises the integral of $f$ over the set of all invariant measures. Extending results of Bousch, Jenkinson and Bremont, we show that the ergodic maximizing measures of functions belonging to a residual subset of the continuous functions may be characterised as those measures which belong to a residual subset of the ergodic measures.
Peroxiredoxin 6 Regulates Glutathione Peroxidase 1-Medited Glutamine Synthase Preservation in the Hippocampus of Chronic Epilepsy Rats

Clasmatodendrosis (an autophagic astroglial degeneration) plays an important role in the regulation of spontaneous seizure duration but not seizure frequency or behavioral seizure severity in chronic epilepsy rats. Recently, it has been reported that N-acetylcysteine (NAC), a precursor to glutathione (GSH), attenuates clasmatodendritic degeneration and shortens spontaneous seizure duration in chronic epilepsy rats, although the underlying mechanisms of its anti-convulsive effects are not fully understood. To elucidate this, the present study was designed to investigate whether NAC affects astroglial glutamine synthase (GS) expression mediated by GSH peroxidase 1 (GPx1) and/or peroxiredoxin 6 (Prdx6) in the epileptic hippocampus. As compared to control animals, GS and GPx1 expressions were upregulated in reactive CA1 astrocytes of chronic epilepsy rats, while their expressions were significantly decreased in clasmatodendritic CA1 astrocytes and reactive astrocytes within the molecular layer of the dentate gyrus. Prdx6 expression was increased in reactive CA1 astrocytes as well as clasmatodendritic CA1 astrocytes. In the molecular layer of the dentate gyrus, Prdx6 expression levels were similar to those in control animals. NAC ameliorated clasmatodendrosis through the increment of GS and GPx1 expressions, while it abolished Prdx6 upregulation. 1-hexadecyl-3-(trifluoroethgl)-sn-glycerol-2 phosphomethanol (MJ33, a selective inhibitor of aiPLA2 activity of Prdx6) alleviated clasmatodendrosis by enhancing GPx1 and GS expressions in clasmatodendritic CA1 astrocytes without changing the Prdx6 level. NAC or MJ33 did not affect GS, GPx1 and Prdx6 expression in astrocytes within the molecular layer of the dentate gyrus. These findings indicate that upregulated aiPLA2 activity of Prdx6 may abolish GPx1-mediated GS preservation and lead to clasmatodendrosis in CA1 astrocytes, which would extend spontaneous seizure duration due to impaired glutamate-glutamine conversion regulated by GS. Therefore, the present data suggest that aiPLA2 activity of Prdx6 in astrocytes may be one of the upstream effectors of seizure duration in the epileptic hippocampus.
Structural design of AlN/GaN superlattices for deep-ultraviolet light-emitting diodes with high emission efficiency

We demonstrate on the basis of first-principles calculations that a AlN/GaN superlattice with one or two GaN monolayers is efficient for near-band-edge C-plane emission of deep-ultraviolet light-emitting diodes. We find that such superlattices lead to a significant increase of the C-plane components of the optical matrix element up to 57% relative to GaN bulk. At the same time, the energy gap of these superlattices is in the deep-UV region, where the shortest emission wavelength is 224 nm. This is remarkably shorter than that in Al-rich AlGaN alloys.
Evaluating Coconut Fiber and Fly Ash Composites for Use in Landfill Retention Layers

This study utilized a series of experimental tests, including the Atterberg limit, standard Proctor, permeability, and direct shear tests. Three composites were investigated: 85% fly ash-10% bentonite (V1), 90% fly ash-5% bentonite (V2), and 95% fly ash-0% bentonite (V3). All composites contained 5% coconut fiber. The plasticity index (PI) increased significantly from 19.10% to 22.15%, with a change in bentonite content from 0% to 10%. All composite met the landfill liner plasticity index standards. The permeability values were low and satisfied local criteria, namely 1.052 x 10-5 (V1), 1.260 x 10-5 (V2), and 1.394 x 10-5 (V3). Composite V2 has the best value with a cohesion value of 55 kPa and a shear angle of 22°. Therefore, composite V3 was the most promising composite as an alternative covering material for landfills because it has the lowest atterberg limits results, the lowest OMC, and the results from the direct shear test that meet the criteria even though it is not the best result among the three variations. However, by supporting the OMC value and good plasticity, the V3 composite was chosen. This study is beneficial and valuable in the engineering, selection, and design of materials used for the construction of landfill liners.
Host Genetic Variants Linked to COVID-19 Neurological Complications and Susceptibility in Young Adults—A Preliminary Analysis

To date, multiple efforts have been made to use genome-wide association studies (GWAS) to untangle the genetic basis for SARS-CoV-2 infection susceptibility and severe COVID-19. However, data on the genetic-related effects of SARS-CoV-2 infection on the presence of accompanying and long-term post-COVID-19 neurological symptoms in younger individuals remain absent. We aimed to examine the possible association between SNPs found in a GWAS of COVID-19 outcomes and three phenotypes: SARS-CoV-2 infection, neurological complications during disease progression, and long-term neurological complications in young adults with a mild-to-moderate disease course. University students (N = 336, age 18–25 years, European ancestry) with or without COVID-19 and neurological symptoms in anamnesis comprised the study sample. Logistic regression was performed with COVID-19-related phenotypes as outcomes, and the top 25 SNPs from GWAS meta-analyses and an MR study linking COVID-19 and cognitive deficits were found. We replicated previously reported associations of the FURIN and SLC6A20 gene variants (OR = 2.36, 95% CI 1.31–4.24) and OR = 1.94, 95% CI 1.08–3.49, respectively) and remaining neurological complications (OR = 2.12, 95% CI 1.10–4.35 for SLC6A20), while NR1H2 (OR = 2.99, 95% CI 1.39–6.69) and TMPRSS2 (OR = 2.03, 95% CI 1.19–3.50) SNPs were associated with neurological symptoms accompanying COVID-19. Our findings indicate that genetic variants related to a severe COVID-19 course in adults may contribute to the occurrence of neurological repercussions in individuals at a young age.
How the Built Environment Moderates Gender Gap in Active Commuting to Schools

This study investigates the influences of built environmental (BE) factors, network design, and sociodemographic factors on active school travel (AST). Although numerous studies have explored these relationships, this study is trying to assess this issue with a focus on gender differences. Data from a cross-sectional sample of children from first to sixth grades from 16 public primary schools exclusive for girls and boys (N = 1260) in Shiraz collected in November 2019 was used. The analysis of the data revealed that, on average, boys are more willing to walk than girls, but that the boys’ tendency to walk is less elastic with respect to distance. Moreover, it is shown that street connectivity for all distance thresholds has a positive relationship with walking level, but the street network choice parameter decreases the chance of walking within an 800 metre threshold. It is demonstrated the need to take gender differences into account in local planning policies to promote AST in a developing country context.

Cranberry Proanthocyanidins as a Therapeutic Strategy to Curb Metabolic Syndrome and Fatty Liver-Associated Disorders

While the prevalence of metabolic syndrome (MetS) is steadily increasing worldwide, no optimal pharmacotherapy is readily available to address its multifaceted risk factors and halt its complications. This growing challenge mandates the development of other future curative directions. The purpose of the present study is to investigate the efficacy of cranberry proanthocyanidins (PACs) in improving MetS pathological conditions and liver complications; C57BL/6J mice were fed either a standard chow or a high fat/high sucrose (HFHS) diet with and without PACs (200 mg/kg), delivered by daily gavage for 12 weeks. Our results show that PACs lowered HFHS-induced obesity, insulin resistance, and hyperlipidemia. In conjunction, PACs lessened circulatory markers of oxidative stress (OxS) and inflammation. Similarly, the anti-oxidative and anti-inflammatory capacities of PACs were noted in the liver in association with improved hepatic steatosis. Inhibition of lipogenesis and stimulation of beta-oxidation could account for PACs-mediated decline of fatty liver as evidenced not only by the expression of rate-limiting enzymes but also by the status of AMPKα (the key sensor of cellular energy) and the powerful transcription factors (PPARα, PGC1α, SREBP1c, ChREBP). Likewise, treatment with PACs resulted in the downregulation of critical enzymes of liver gluconeogenesis, a process contributing to increased rates of glucose production in type 2 diabetes. Our findings demonstrate that PACs prevented obesity and improved insulin resistance likely via suppression of OxS and inflammation while diminishing hyperlipidemia and fatty liver disease, as clear evidence for their strength of fighting the cluster of MetS abnormalities.
Intrawire resistance, AC loss and strain dependence of critical current in MgB2 wires with and without cold high-pressure densification

The intrawire resistance and alternating current (AC) loss of two MgB2 wires with filaments surrounded by Nb barriers have been measured and analyzed. Relatively high values of filament-to-matrix contact resistivity are found in the MgB2 wires; the values are two or three orders higher than those commonly found in NbTi or Nb3Sn wires. Considering the high porosity of the MgB2 filaments, cold high-pressure densification has been applied on the two MgB2 wires to investigate its impact on intrawire resistance and AC loss. The intrawire resistance is measured with a direct four-probe voltage-current method at various temperatures. The AC loss is measured by vibrating sample magnetometer measurements at 4.2 K. In addition to the intrawire resistance measurements, the critical current of MgB2 wires before and after densification is measured with a U-shaped bending spring at 4.2 K as function of axial strain. The critical current in densified MgB2 wires is found to be higher than that in the same wire without densification; it is also less sensitive to the applied axial strain.

An ADMM-based Algorithm for Zeroth-order Stochastic Optimization over Distributed Processing Networks

—In this paper, we address the problem of stochastic optimization over distributed processing networks, which is motivated by machine learning applications performed in data centers. In this problem, each of a total n nodes in a network receives stochastic realizations of a private function f i ( x ) and aims to reach a common value that minimizes (cid:80) ni =1 f i ( x ) via local updates and communication with its neighbors. We focus on zeroth-order methods where only function values of stochastic realizations can be used. Such kind of methods, which are also called derivative-free, are especially important in solving real-world problems where either the (sub)gradients of loss functions are inaccessible or inefﬁcient to be evaluated. To this end, we propose a method called Distributed Stochastic Alternating Direction Method of Multipliers (DS-ADMM) which can choose to use two kinds of gradient estimators for different assumptions. The convergence rates of DS-ADMM are O ( n (cid:112) k log (2 k ) /T ) for general convex loss functions and O ( nk log (2 kT ) /T ) for strongly convex functions, where k is the dimension of domain and T is the time horizon of the algorithm. The rates can be improved to O ( n/ √ T ) and O ( n log T/T ) if objective functions have Lipschitz gradients. All these results are better than previous distributed zeroth-order methods. Lastly, we demonstrate the performance of DS-ADMM via experiments of two examples called distributed online least square and distributed support vector machine arising in estimation and classiﬁcation tasks.
Digital Explosion and Entrepreneurship Education: Impact on Promoting Entrepreneurial Intention for Business Students

This study aims to examine the effect of entrepreneurship education and artificial intelligence (AI) development on entrepreneurial intentions while investigating the mediating role of perceived behavioral control. The proposed model also accounts for individual and contextual socioeconomic factors. This study tries to fill the gap in the entrepreneurship literature, which is still lacking with respect to the impact of new technologies on entrepreneurship intentions and shows conflicting results regarding the influence of entrepreneurship education. Our study surveyed 223 business students in Lebanon. The context of this study is of high importance, particularly since the country is currently facing a deep, multifaced political, economic, and financial crisis, and entrepreneurship might be considered an important channel for generating basic sources of income, steering the recovery process, and increasing Lebanese resilience against this highly unstable economy. The structural equation modeling technique (SEM) was conducted to validate the hypotheses. The results show that perceived behavioral control fully mediates the relations between performance expectancy of AI solutions, entrepreneurship education, and entrepreneurial intention. Risk aversion and social support exert a direct impact on entrepreneurial intentions. The findings highlight the need to account for entrepreneurship education and AI development when analyzing entrepreneurial intentions.
Genome-Wide Association Study and Genomic Prediction on Plant Architecture Traits in Sweet Corn and Waxy Corn

Sweet corn and waxy corn has a better taste and higher accumulated nutritional value than regular maize, and is widely planted and popularly consumed throughout the world. Plant height (PH), ear height (EH), and tassel branch number (TBN) are key plant architecture traits, which play an important role in improving grain yield in maize. In this study, a genome-wide association study (GWAS) and genomic prediction analysis were conducted on plant architecture traits of PH, EH, and TBN in a fresh edible maize population consisting of 190 sweet corn inbred lines and 287 waxy corn inbred lines. Phenotypic data from two locations showed high heritability for all three traits, with significant differences observed between sweet corn and waxy corn for both PH and EH. The differences between the three subgroups of sweet corn were not obvious for all three traits. Population structure and PCA analysis results divided the whole population into three subgroups, i.e., sweet corn, waxy corn, and the subgroup mixed with sweet and waxy corn. Analysis of GWAS was conducted with 278,592 SNPs obtained from resequencing data; 184, 45, and 68 significantly associated SNPs were detected for PH, EH, and TBN, respectively. The phenotypic variance explained (PVE) values of these significant SNPs ranged from 3.50% to 7.0%. The results of this study lay the foundation for further understanding the genetic basis of plant architecture traits in sweet corn and waxy corn. Genomic selection (GS) is a new approach for improving quantitative traits in large plant breeding populations that uses whole-genome molecular markers. The marker number and marker quality are essential for the application of GS in maize breeding. GWAS can choose the most related markers with the traits, so it can be used to improve the predictive accuracy of GS.
THE LOW-LEVEL SEA BREEZE OF NORTHWEST WASHINGTON

Abstract Resultant winds, mean pressures, and mean pressure gradients are presented for each hour of the day for July and August at stations of northwest Washington. The end point of the resultant wind vector in some cases turns clockwise, in some cases counterclockwise. Circular, elliptical, and more complicated hodographs are found. The results are discussed in connection with recent sea-breeze theory. In some locations the pressure-gradient force changes in direction during the day, apparently as a result of topographical constraint, and in a manner which is consistent with the sense of rotation of the end point of the resultant wind vector and the shape of the hodograph. Spatial differences of resultant wind components suggest that the diurnal variation of stratus amount is related in part to vertical motion associated with the sea-breeze circulation. Hodographs for days selected for cloudiness show that the sea-breeze circulation in northwest Washington takes place on a huge scale. Applications of th.
On the existence of nonregular ultrafilters and the cardinality of ultrapowers

Assuming the consistency of huge cardinals, we prove that W3 can carry an ultrafilter D such that W1 3/D has cardinality W3. (Hence D is not (W3, ol) regular. ) Similarly W2 can carry an ultrafilter D such that w'2/D has cardinality w2. (Hence D is not (CA2, o) regular. ) 0. Introduction. When ultrafilters and ultrapowers (see [4]) were introduced, the problem of determining the cardinality of the ultrapower given the cardinality of the basis structure and of the index set became of interest (see [8]). As was already noted in [4], the problem can be completely settled, if one assumes that the ultrafilter in question is regular (see below for definition). Under the assumption of regularity the cardinality of the ultrapower has largest cardinality possible, i.e. if M is a structure of cardinality a > X and D is a uniform regular ultr4filter on an index set I of cardinality ,8, then M'/D has cardinality a. The problem whether every ultrafilter is regular, was posed by Keisler in [9], and partial answers were obtained in the constructible universe by Jensen and then improved by Prikry [14] who showed that if V = L then every uniform ultrafilter on w,, is regular. Results of Benda and Ketonen [2], Kanamori [6] and finally Ketonen [10] indicate the problem is closely connected with the existence of large cardinals. In particular (see [10]) if K + carries a uniform ultrafilter which is not (K , K) regular, then 0# exists. On the other hand large cardinals immediately imply the existence of nonregular ultrafilters, see definition below. Note that a regular ultrafilter on K+ iS (K+, K) regular though the converse does not necessarily hold. If D is an WI complete, nonprincipal ultrafilter on a cardinal K, then D is not regular: Note that K has to be at least as large as the first measurable in order to carry an w, complete ultrafilter. Keisler's problem is of course much more interesting for smaller cardinals like (O1, W2 etc., and we attend this version of the problem. There is one fact known about the same problem for the continuum; if the continuum carries an w, saturated ideal then it carries a nonregular ultrafilter. Note that under this assumption the continuum is very large and this Received by the editors August 1, 1977 and, in revised form, September 26, 1977. AMS (MOS) subject classifications (1970).

Homely Orderings in Times of Stay-At-Home Measures

Abstract The stay-at-home measures imposed by governments to counteract the COVID-19 pandemic have drawn attention to the domestic sphere. Besides spending much more time at home in general, people also required the private sphere to fulfill multiple functions, including as workplaces, schools, and fitness centers. Within a qualitative social research framework, the paper examines how people in Vienna, Austria re-ordered their homes during lockdowns to address these challenges. We discuss ordering work as a form of care work regarding the home’s conception, realization and maintenance, and understand the home as being produced in and through practices, including ordering practices. In particular, we are interested in whether and how ordering practices gained higher significance during the pandemic, and in how—by reordering their homes—people re-negotiated their social relations and the inequalities connected to care work and the home.
