The impact of typological similarities and differences between German and Italian on the acquisition of language-specific phonetic cues in bilingual children: insights from the T-complex.

Introduction: Lateral temporal neural measures (Na and T-complex Ta and Tb) of the auditory evoked potential (AEP) index auditory/speech processing and have been observed in children and adults. While Na is already present in children under 4 years of age, Ta emerges from 4 years of age, and Tb appears even later. The T-complex has been found to be sensitive to language experience in Spanish-English and Turkish-German children and adults.

Developing Guidelines for Conducting Stigma Research With Transgender and Nonbinary Individuals: Protocol for Creation of a Trauma-Informed Approach to Research.

Background: Transgender and nonbinary individuals have received increasing attention within HIV research, with studies documenting the pervasive role stigma plays in creating and sustaining health inequities. However, the proliferation of HIV stigma research with this population has also raised concerns about research practices that may unintentionally stigmatize or retraumatize the very communities they are designed to benefit. Conducting stigma research is critical for generating accurate information about HIV epidemiology, risk and protective factors, and intervention strategies for transgender and nonbinary individuals.

Egg shape and color mediate acceptance thresholds in diverse avian host species with different rates of antiparasitic egg rejection.

Eggshell recognition in parental birds is vital for nest management, defense against brood parasitism, optimal embryonic development, and minimizing disease and predation risks. This process relies on acceptance thresholds balancing the risk of rejecting own eggs against the benefit of excluding foreign ones, following signal detection theory. We investigated the role of object shape in egg rejection decisions among three host species of the brown-headed cowbird (Molothrus ater), each with a varying known response to parasitic eggs.

Development of Receptor Desolvation Scoring and Covalent Sampling in DOCK 6: Methods Evaluated on a RAS Test Set.

Molecular docking methods are widely used in drug discovery efforts. RAS proteins are important cancer drug targets, and are useful systems for evaluating docking methods, including accounting for solvation effects and covalent small molecule binding. Water often plays a key role in small molecule binding to RAS proteins, and many inhibitors─including FDA-approved drugs─covalently bind to oncogenic RAS proteins.

Investigation and modeling of land use effects on water quality in two NYC water supply streams.

The paired watershed monitoring approach is widely used to investigate hydrologic processes and water quality, providing streamflow and water quality records for long-term trend analysis, as well as data for developing and testing hydrologic models. In this study we use 20 years of streamflow and water quality data, along with a watershed model, to examine sources of stream nutrients and their changes over time in two small streams within the New York City water supply system. We compare sources and trends in stream nitrate and dissolved phosphorus in the urbanized Amawalk watershed with those of the predominantly forested Boyd Corners watershed in the Croton system of reservoirs.

Numerical dosimetry of specific absorption rate of insects exposed to far-field radiofrequency electromagnetic fields.

Purpose: This paper reports a study of electromagnetic field (EMF) exposure of several adult insects: a ladybug, a honey bee worker, a wasp, and a mantis at frequencies ranging from 2.5 to 100 GHz. The purpose was to estimate the specific absorption rate (SAR) in insect tissues, including the brain, in order to predict the possible biological effects caused by EMF energy absorption.

Promoting trans patient autonomy in surgical preparation for phalloplasty and metoidioplasty: results from a community-based cross-sectional survey and implications for preoperative assessments.

Background: Some transgender and nonbinary people undergo phalloplasty and/or metoidioplasty as part of their medical transition process. Across surgical disciplines, a variety of resources are used to assist patients who are preparing for surgeries, including educational materials, workshops, peer support, and lifestyle changes. For gender-affirming surgeries, patients undergoing assessments to discern whether they are ready to undergo the surgery, and to assist them in achieving preparedness when needed.

Optimization of Existing RNA Visualization Methods Reveals Novel Dendritic mRNA Dynamics.

Background: Spatial-temporal control of mRNA translation in dendrites is important for synaptic plasticity. In response to pre-synaptic stimuli, local mRNA translation can be rapidly triggered near stimulated synapses to supply the necessary proteins for synapse maturation or elimination, and 3' untranslated regions (UTRs) are responsible for proper localization of mRNAs in dendrites. Although is a robust technique for analyzing RNA localization in fixed neurons, live-cell imaging of RNA dynamics remains challenging.

The songbird connectome (OSCINE-NET.ORG): structure-function organization beyond the canonical vocal control network.

Background: Understanding the neural basis of behavior requires insight into how different brain systems coordinate with each other. Existing connectomes for various species have highlighted brain systems essential to various aspects of behavior, yet their application to complex learned behaviors remains limited. Research on vocal learning in songbirds has extensively focused on the vocal control network, though recent work implicates a variety of circuits in contributing to important aspects of vocal behavior.

Thermally Stable Anthracene-Based 2D/3D Heterostructures for Perovskite Solar Cells.

Bulky organic cations are used in perovskite solar cells as a protective barrier against moisture, oxygen, and ion diffusion. However, bulky cations can introduce thermal instabilities by reacting with the near-surface of the 3D perovskite forming low-dimensional phases, including 2D perovskites, and by diffusing away from the surface into the film. This study explores the thermal stability of CsFAPbI 3D perovskite surfaces treated with two anthracene salts─anthracen-1-ylmethylammonium iodide (AMAI) and 2-(anthracen-1-yl)ethylammonium iodide (AEAI)─and compares them with the widely used phenethylammonium iodide (PEAI).

Efficacy of traditional and gamified attention bias modification for depression: Study protocol for a randomized controlled trial.

Cognitive models posit that negatively biased attention toward dysphoric information has a causal role in the maintenance of depression-related psychopathology. Attention bias modification (ABM) tests this idea by altering an attentional bias and examining subsequent effects on depression. Prior work finds that ABM alters negatively biased attention for dysphoric information and reduces depression; however, a number of studies have failed to show these effects.

A neurodegenerative cellular stress response linked to dark microglia and toxic lipid secretion.

The brain's primary immune cells, microglia, are a leading causal cell type in Alzheimer's disease (AD). Yet, the mechanisms by which microglia can drive neurodegeneration remain unresolved. Here, we discover that a conserved stress signaling pathway, the integrated stress response (ISR), characterizes a microglia subset with neurodegenerative outcomes.

Non-classicality and the effect of one photon.

The quantum interference effects of mixing the most non-classical states of light, number states, with the most classical-like of pure field states, the coherent state, are investigated. We demonstrate how the non-classicality of a single photon when mixed with a coherent field can transform the statistical properties of the output and further demonstrate that the entanglement of the output is independent of the coherent state amplitude.This article is part of the theme issue 'The quantum theory of light'.

Low Parental Empathy Predicts Callous-Unemotional Traits in Children With Enhanced Autonomic Sensitivity to the Environment.

Introduction: Recent evidence suggests that autonomic nervous system functioning can reflect individual differences in sensitivity to the environment, which in turn moderates the effects of family context on psychopathic and antisocial behaviour. Although some preliminary research suggests that the coordination of the sympathetic (SNS) and parasympathetic (PNS) branches of the autonomic nervous system may reflect sensitivity to environmental influences, the majority of research to date has been limited in its focus on just one branch, and little is known about the effects of parental empathy on a child's psychopathic-like traits. This study aimed to address this gap by examining if the SNS and PNS jointly moderate the prospective contribution of parental empathy to youth psychopathic-like traits.

Software codesign between end users and developers to enhance utility for biodiversity conservation.

Creating software tools that address the needs of a wide range of decision-makers requires the inclusion of differing perspectives throughout the development process. Software tools for biodiversity conservation often fall short in this regard, partly because broad decision-maker needs may exceed the toolkits of single research groups or even institutions. We show that participatory, collaborative codesign enhances the utility of software tools for better decision-making in biodiversity conservation planning, as demonstrated by our experiences developing a set of integrated tools in Colombia.

Single-Walled Carbon Nanotubes as Optical Transducers for Nanobiosensors In Vivo.

Semiconducting single-walled carbon nanotubes (SWCNTs) may serve as signal transducers for nanobiosensors. Recent studies have developed innovative methods of engineering molecularly specific sensors, while others have devised methods of deploying such sensors within live animals and plants. These advances may potentiate the use of implantable, noninvasive biosensors for continuous drug, disease, and contaminant monitoring based on the optical properties of single-walled carbon nanotubes (SWCNTs).

Nonlinear Elasticity of Amorphous Silicon and Silica from Density Functional Theory.

Density functional theory calculations and a finite deformation method are used to calculate second- and, most notably, third-order elastic constants of amorphous silicon and amorphous silicon dioxide, as represented by model structures generated via melt-quench force-field molecular dynamics simulations. Linear and nonlinear elastic constants are used to deduce macroscopic elastic moduli, such as the bulk and shear moduli, their pressure derivatives, and the elastic Grüneisen parameter. Our calculations show that the elastic properties of amorphous silicon reach the isotropic elastic limit within the nanometer length scale, attaining characteristics, both linear and nonlinear, comparable to those of crystalline silicon.

Loss of STAT3 in osteoblasts has detrimental and sexually dimorphic effects on skeletal development.

Studies with genetically modified mice have implicated the transcriptional regulator STAT3 as a key modulator of bone development. STAT3-OKO knockout mouse lines were generated in two genetic backgrounds, pure C57BL/6 (STAT3-OKO-BL) and mixed C57BL/6, CD1 (STAT3-OKO-M). Both lines exhibited defective postnatal bone development resulting in reduced body weight and shortened femurs that displayed low bone mineral density as well as cortical widening and thinning in the diaphyseal region.

Computational analysis of the alpha-2 domain of apolipoprotein B - 100, a potential triggering factor in LDL aggregation.

Atherosclerosis, the major underlying cause of cardiovascular disease, is believed to arise from the accumulation of low-density lipoprotein (LDL) in the arterial subendothelial space, ultimately leading to plaque formation. It is proposed that the accumulation of LDL is linked to its intrinsic aggregation propensity. Although the native LDL is not prone to aggregation, LDL(-), an electronegative LDL characterized in the plasma, has been shown to prime LDL aggregation in a domino-like behavior similar to amyloidogenic proteins.

Nuclear quantum effects on glassy water under pressure: Vitrification and pressure-induced transformations.

We perform classical molecular dynamics (MD) and path-integral MD (PIMD) simulations of H2O and D2O using the q-TIP4P/F model over a wide range of temperatures and pressures to study the nuclear quantum effects (NQEs) on (i) the vitrification of liquid water upon isobaric cooling at different pressures and (ii) pressure-induced transformations at constant temperature between low-density amorphous and high-density amorphous ice (LDA and HDA) and hexagonal ice Ih and HDA. Upon isobaric cooling, classical and quantum H2O and D2O vitrify into a continuum of intermediate amorphous ices (IA), with densities in-between those of LDA and HDA (depending on pressure). Importantly, the density of the IA varies considerably if NQEs are included (similar conclusions hold for ice Ih at all pressures studied).

Peer social support moderates the impact of ethnoracial discrimination on mental health among young sexual minority men of color.

Few studies have examined developmentally relevant sources of resilience, such as peer social support, among young sexual minority men (SMM) of color experiencing discrimination and mental health distress. To address this gap in the literature, we examined the role of peer social support in the association between discrimination and mental health distress in a sample of young SMM of color. Ninety-four cisgender young SMM of color (aged 16-29) were recruited through community-based organizations in the New York City metropolitan area as part of an effectiveness trial of a tailored Motivational Interviewing intervention.

Fission yeast essential nuclear pore protein Nup211 regulates the expression of genes involved in cytokinesis.

Nuclear pore proteins control nucleocytoplasmic transport; however, certain nucleoporins play regulatory roles in activities such as transcription and chromatin organization. The fission yeast basket nucleoporin Nup211 is implicated in mRNA export and is essential for cell viability. Nup211 preferentially associates with heterochromatin, however, it is unclear whether it plays a role in regulating transcription.

Dissemination of accurate information regarding the microbial-driven composting process is critical to positive outcomes.

Aim: To describe the content of news articles addressing composting.

Polarizability, plasmons and damping in pseudospin-1 gapped materials with a flat band.

The subject of our present investigation is the collective electronic properties of various types of pseudospin-1 Dirac-cone materials with a flat band and finite bandgaps in their low-energy spectra. Specifically, we have calculated the dynamical polarization, plasmon dispersions, as well as their decay rates due to Landau damping and presented the closed-form analytical expressions for the wave function overlaps for both the gapped dice lattice and the Lieb lattice. The gapped dice lattice is a special case of the more general-T3model such that its band structure is symmetric and the flat band remains dispersionless.
