Adapting lateral stepping control to walk on winding paths.

Most often, gait biomechanics is studied during straight-ahead walking. However, real-life walking imposes various lateral maneuvers people must navigate. Such maneuvers challenge people's lateral balance and can induce falls.

Aerosol transport and associated boundary layer thermodynamics under contrasting synoptic conditions over a semiarid site.

Understanding the kinematics of aerosol horizontal transport and vertical mixing near the surface, within the atmospheric boundary layer (ABL), and in the overlying free troposphere (FT) is critical for various applications, including air quality and weather forecasting, aviation, road safety, and dispersion modeling. Empirical evidence of aerosol mixing processes within the ABL during synoptic-scale events over arid and semiarid regions (i.e.

Ecology of prophage-like elements in Bacillus subtilis at global and local geographical scales.

Prophages constitute a substantial portion of bacterial genomes, yet their effects on hosts remain poorly understood. We examine the abundance, distribution, and activity of prophages in Bacillus subtilis using computational and laboratory analyses. Genome sequences from the NCBI database and riverbank soil isolates reveal prophages primarily related to mobile genetic elements in laboratory strains.

Design and Implementation of a Binary Phase-Shift Keying Frequency Diverse Array: Considerations and Challenges.

The frequency diverse array (FDA) is an architecture capable of beamforming in both range and angle, improving upon the traditional phased array (PA) which can only achieve beamforming in angle. The FDA employing directional modulation (DM) for secure directional communications (SDC) can reduce bit error rates (BERs) in both range and angle, again improving upon the traditional PA which can only reduce BER in angle. In this paper, we document the challenges involved in the design and implementation of a two-element linear FDA employing fast-time binary phase-shift keying (BPSK) modulations.

Three-Dimensional Reconstruction of Road Structural Defects Using GPR Investigation and Back-Projection Algorithm.

Ground-Penetrating Radar (GPR) has demonstrated significant advantages in the non-destructive detection of road structural defects due to its speed, safety, and efficiency. This paper proposes a three-dimensional (3D) reconstruction method for GPR images, integrating the back-projection (BP) imaging algorithm to accurately determine the size, location, and other parameters of road structural defects. Initially, GPR detection images were preprocessed, including direct wave removal and wavelet denoising, followed by the application of the BP algorithm to effectively restore the defect's location and size.

An Overview of Zika Virus and Zika Virus Induced Neuropathies.

Flaviviruses pose a major public health concern across the globe. Among them, Zika virus (ZIKV) is an emerging and reemerging arthropod-borne flavivirus that has become a major international public health problem following multiple large outbreaks over the past two decades. The majority of infections caused by ZIKV exhibit mild symptoms.

Radiation Damage Mitigation in FeCrAl Alloy at Sub-Recrystallization Temperatures.

Traditional defect recovery methods rely on high-temperature annealing, often exceeding 750 °C for FeCrAl. In this study, we introduce electron wind force (EWF)-assisted annealing as an alternative approach to mitigate irradiation-induced defects at significantly lower temperatures. FeCrAl samples irradiated with 5 MeV Zr ions at a dose of 10 cm were annealed using EWF at 250 °C for 60 s.

Exploring Co-Occurrence Patterns to Understand Epiphyte-Liana Interactions.

Although epiphytes and lianas share the same habitat, most research has treated these two groups independently. This study aimed to evaluate the co-occurrence of vascular epiphytes and lianas in the subtropical montane forests of northwestern Argentina. We recorded epiphyte cover and liana basal area on trees ≥ 10-cm-dbh in 120 20 × 20 m plots in the Sierra de San Javier (Tucumán, Argentina).

Sequential Defense Strategies: From Ant Recruitment to Leaf Toughness.

Plants express many types of defenses in response to herbivory damage. These defenses can be displayed as a sequence or they can overlap, increasing efficiency in protection. However, leaf defense shifts during leaf development, including extrafloral nectaries (EFNs), are neglected in natural tropical systems.

Coordination Chemistry of Mixed-Donor Pyridine-Containing Macrocyclic Ligands: From Optical to Redox Chemosensors for Heavy Metal Ions.

2,8-Dithia-5-aza-2,6-pyridinophane () has been used as a receptor unit in the construction of the conjugated redox chemosensor 5-ferrocenylmethyl-2,8-dithia-5-aza-2,6-pyridinophane (). In order to further explore the coordination chemistry of , and comparatively, that of its structural analogue 2,11-dithia-5,8-diaza-2,6-pyridinophane (), featuring two secondary nitrogen atoms in the macrocyclic unit, the crystal structures of the new synthesised complexes [Pb()(ClO)]·½CHCN, [Cu()](ClO)·CHCN and [Cd()(NO)]NO were determined by X-ray diffraction analysis. The electrochemical response of towards the metal ions Cu, Zn, Cd, Hg, and Pb was investigated by cyclic voltammetry (CV) in CHCl/CHCN 0.

Justice and hostility: The moderated mediating effect of sports behavior on bullying.

The increasingly frequent phenomenon of school bullying among high school students has become one of the threats hindering their physical and mental health and disrupting the harmonious atmosphere of campuses. Engaging in sports behavior, recognized as a critical means of enhancing both physical and mental well-being, may contribute significantly to mitigating psychological distress among high school students and reducing the prevalence of school bullying. This study surveyed 970 high school students through a structured questionnaire to investigate the relationships between victim justice sensitivity, hostile attribution bias, and school bullying.

Large enhancement of ferroelectric properties of perovskite oxides via nitrogen incorporation.

Perovskite oxides have a wide variety of physical properties that make them promising candidates for versatile technological applications including nonvolatile memory and logic devices. Chemical tuning of those properties has been achieved, to the greatest extent, by cation-site substitution, while anion substitution is much less explored due to the difficulty in synthesizing high-quality, mixed-anion compounds. Here, nitrogen-incorporated BaTiO thin films have been synthesized by reactive pulsed-laser deposition in a nitrogen growth atmosphere.

Raman Signature of Stripe Domains in Monolayer WMoS Alloys.

We study the Raman signature of stripe domains in monolayer WMoS alloys, characterized using experimental techniques and density functional theory (DFT) calculations. These stripe domains were found in star-shaped monolayer WS exhibiting a high concentration of molybdenum (Mo) atoms in its central region, and unique Raman peaks that were not previously reported. We attribute these peaks to the splitting of the original doubly degenerate E modes, arising from the lower symmetry of the W-Mo stripe domains.

Chiral exceptional point enhanced active tuning and nonreciprocity in micro-resonators.

Exceptional points (EPs) have been extensively explored in mechanical, acoustic, plasmonic, and photonic systems. However, little is known about the role of EPs in tailoring the dynamic tunability of optical devices. A specific type of EPs known as chiral EPs has recently attracted much attention for controlling the flow of light and for building sensors with better responsivity.

The association of lung consolidation and respiratory pathogens identified at weaning on the growth performance of beef on dairy calves.

This observational study evaluated the relationship between lung consolidation observed at weaning and calf ADG, and the association of pathogen shedding at weaning on ADG in beef × dairy calves up to 238 d. Beef × Holstein calves (n = 143) were sourced from 2 dairies. Calves were managed in 3 cohorts and fed milk replacer and calf starter preweaning.

The effect of the biohydrogenation-induced milk fat depression in dairy cows on milk odd and branched chain fatty acids across multiple studies.

Diet-induced milk fat depression (MFD) caused by UFA, and low fiber diets results in an increase in alternate rumen biohydrogenation intermediates. The impact of these MFD-inducing diets on milk odd and branched chain fatty acids (OBCFA) is not well known. The first objective of this study was to characterize the time course of changes in OBCFA in milk fat during induction and recovery of MFD induced with a high UFA and low fiber diet in 3 separate experiments.

A longitudinal examination of factors predicting maternal permissiveness toward underage student drinking across the first three years of college.

Parental permissiveness of drinking is a reliable predictor of college drinking, but there is little known about factors that predict such permissiveness. This study seeks to examine factors that predict two potentially different facets of permissiveness: perceived general approval of alcohol use and perceived drinking limits. Additionally, we explored how these facets mediate the relationship between the predictors of permissiveness and subsequent college drinking and related consequences.

Proteoform Identification and Quantification Based on Alignment Graphs.

Motivation: Proteoforms are the different forms of a proteins generated from the genome with various sequence variations, splice isoforms, and post-translational modifications. Proteoforms regulate protein structures and functions. A single protein can have multiple proteoforms due to different modification sites.

Children's executive functioning and health behaviors across pediatric life stages and ecological contexts.

Executive functioning (EF) has been linked to chronic disease risk in children. Health behaviors are thought to partially explain this association. The current cross-sectional study evaluated specific domains of EF and varied health behaviors in three pediatric life stages.

Cross-tissue comparison of epigenetic aging clocks in humans.

Epigenetic clocks are a common group of tools used to measure biological aging-the progressive deterioration of cells, tissues, and organs. Epigenetic clocks have been trained almost exclusively using blood-based tissues, but there is growing interest in estimating epigenetic age using less-invasive oral-based tissues (i.e.

Facile Design of Highly Stretchable and Conductive Crumpled Graphene/NiS Films for Multifunctional Applications.

The cost-effective and scalable synthesis and patterning of soft nanomaterial composites with improved electrical conductivity and mechanical stretchability remains challenging in wearable devices. This work reports a scalable, low-cost fabrication approach to directly create and pattern crumpled porous graphene/NiS nanocomposites with high mechanical stretchability and electrical conductivity through laser irradiation combined with electrodeposition and a pre-strain strategy. With modulated mechanical stretchability and electrical conductivity, the crumpled graphene/NiS nanocomposite can be readily patterned into target geometries for application in a standalone stretchable sensing platform.

Towards a 'people and nature' paradigm for biodiversity and infectious disease.

Zoonotic and vector-borne infectious diseases are among the most direct human health consequences of biodiversity change. The COVID-19 pandemic increased health policymakers' attention on the links between ecological degradation and disease, and sparked discussions around nature-based interventions to mitigate zoonotic emergence and epidemics. Yet, although disease ecology provides an increasingly granular knowledge of wildlife disease in changing ecosystems, we still have a poor understanding of the net consequences for human disease.

Proximity ferroelectricity in wurtzite heterostructures.

Proximity ferroelectricity is an interface-associated phenomenon in electric-field-driven polarization reversal in a non-ferroelectric polar material induced by one or more adjacent ferroelectric materials. Here we report proximity ferroelectricity in wurtzite ferroelectric heterostructures. In the present case, the non-ferroelectric layers are AlN and ZnO, whereas the ferroelectric layers are AlBN, AlScN and ZnMgO.
