The competing controls of glaciers, precipitation, and vegetation on high-mountain fluvial sediment yields.

Investigating erosion and river sediment yield in high-mountain areas is crucial for understanding landscape and biogeochemical responses to environmental change. We compile data on contemporary fluvial suspended sediment yield (SSY) and 12 environmental proxies from 151 rivers in High Mountain Asia surrounding the Tibetan Plateau. We demonstrate that glaciers exert a first-order control on fluvial SSYs, with high precipitation nonlinearly amplifying their role, especially in high-glacier cover basins.

Distinguishing among standing postures with machine learning-based classification algorithms.

The purpose of our study was to evaluate the accuracy with which classification algorithms could distinguish among standing postures based on center-of-pressure (CoP) trajectories. We performed a secondary analysis of published data from three studies: Study A) assessment of balance control on firm or foam surfaces with eyes-open or closed, Study B) quantification of postural sway in forward-backward and side-to-side directions during four standing-balance tasks that differed in difficulty, and Study C) an evaluation of the impact of two modes of transcutaneous electrical nerve stimulation on balance control in older adults. Three classification algorithms (decision tree, random forest, and k-nearest neighbor) were used to classify standing postures based on the extracted features from CoP trajectories in both the time and time-frequency domains.

Response of parvalbumin interneurons and perineuronal nets in rat medial prefrontal cortex and lateral amygdala to stressor controllability.

Behavioral control over a stressor limits the impact of the stressor being experienced and produces enduring changes that reduce the effects of future stressors. In rats, these stress-buffering effects of control (escapable stress, ES) require activation of the medial prefrontal cortex (mPFC) and prevent the typical amygdala-dependent behavioral outcomes of uncontrollable stress (inescapable stress, IS). Parvalbumin (PV) interneurons regulate output of excitatory neurons, and most mPFC PV neurons are surrounded by perineuronal nets (PNNs), which regulate firing.

Bulk Layering Effects of Ag and Cu for Tandem CO Electrolysis.

The electrochemical reduction of carbon dioxide (CO) presents an opportunity to close the carbon cycle and obtain sustainably sourced carbon compounds. In recent years, copper has received widespread attention as the only catalyst capable of meaningfully producing multi-carbon (C) species. Notably carbon monoxide (CO) can also be reduced to C compounds on copper, motivating tandem systems that combine copper and CO-producing species, like silver, to enhance overall C selectivities.

Juno Observations of Jupiter's Magnetodisk Plasma: Implications for Equilibrium and Dynamics.

The Jovian magnetodisk plays an essential role in the dynamics of the Jupiter system by coupling its various components. Here, we investigate the Juno (JADE, JEDI, and MAG) observations of the magnetodisk within 20-80 Jupiter radii ( ) in the 0-6 hr local time sector. JADE and JEDI data are combined to generate equatorial plane distributions of density, pressure, temperature, and anisotropy of electrons, protons, and heavy ions.

GOES-R Series X-Ray Sensor (XRS): 1. Design and Pre-Flight Calibration.

The X-Ray Sensor (XRS) has been making full-disk observations of the solar soft X-ray irradiance onboard National Oceanic and Atmospheric Administration's (NOAA) Geostationary Operational Environmental Satellites since 1975. Critical information about solar activity for space weather operations is provided by XRS measurements, such as the classification of solar flare magnitude based on X-ray irradiance level. The GOES-R series of XRS sensors, with the first in the series launched in November 2016, has a completely different instrument design compared to its predecessors, GOES-1 through GOES-15.

Distilling the Evolving Contributions of Anthropogenic Aerosols and Greenhouse Gases to Large-Scale Low-Frequency Surface Ocean Changes Over the Past Century.

Anthropogenic aerosols (AER) and greenhouse gases (GHG)-the leading drivers of the forced historical change-produce different large-scale climate response patterns, with correlations trending from negative to positive over the past century. To understand what caused the time-evolving comparison between GHG and AER response patterns, we apply a low-frequency component analysis to historical surface ocean changes from CESM1 single-forcing large-ensemble simulations. While GHG response is characterized by its first leading mode, AER response consists of two distinct modes.

Immigration Policy Climate and contraceptive use among Mexican-origin women in the United States: Support for the "spill-over" hypothesis.

Objectives: This study aimed to examine the association between state-level Immigration Policy Climate (IPC) and the use of most or moderately effective contraceptive methods among US-born White, US-born Mexican-origin, and foreign-born Mexican-origin women.

Study Design: We linked nationally representative survey data from three waves of the National Survey of Family Growth (2013-2019) with a novel and dynamic state-level measure of IPC. We compared the use of a most or moderately effective contraceptive method at the time of the survey among the three ethnicity and nativity groups alone and as an interaction with state IPC index score above or below the national mean in the year of the survey.

Supporting knowledge justice through community science air quality monitoring and a reciprocal reporting process.

In community science on air quality, low-cost air monitors have emerged as an opportunity to democratize data reporting and support knowledge justice by providing participants with instantaneous access to air quality data. In this study, we equipped residents in four environmental justice communities in North Denver with low-cost air monitors to collect real-time air quality data for four separate 30-day field deployments over two years. We conceptualize an improvement to conventional report-back processes by suggesting a 3-part approach - a reciprocal reporting process that includes 1) bidirectional open channels of communication with participants, 2) democratized data access via instant monitor data and written data summaries, and 3) responsive intervention opportunities to respond in real-time to participants air quality concerns.

Ideological diversity of media consumption predicts COVID-19 vaccination.

This study examines the relationship between respondents' vaccine hesitancy, reported media consumption patterns, ideological leanings, and trust in science. A large-scale survey conducted in the US in 2022 (N = 1,646) assessed self-reported COVID-19 vaccination, trust in science, and reported media consumption. Findings show that, regardless of personal ideology, individuals who consumed less conservative media and had a more ideologically diverse media diet were more likely to be fully vaccinated and boosted.

Search for Soft Unclustered Energy Patterns in Proton-Proton Collisions at 13 TeV.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

Stable isotopic signature of dissimilatory nitrate reduction is robust against enzyme mutation.

The proportionality of oxygen-to-nitrogen isotope effects (ε/ε) is used as a key isotopic signature of nitrogen cycling processes in the environment. Dissimilatory nitrate reduction is observed to have an ε/ε proportionality of ~0.9 in marine and ~0.

The extraction of neural strategies from the surface EMG: 2004-2024.

This review follows two previous papers [Farina et al. 96: 1486-1495, 2004; Farina et al. 117: 1215-1230, 2014] in which we reflected on the use of surface electromyography (EMG) in the study of the neural control of movement.

Lifetime brain atrophy estimated from a single MRI: measurement characteristics and genome-wide correlates.

A measure of lifetime brain atrophy (LBA) obtained from a single magnetic resonance imaging (MRI) scan could be an attractive candidate to boost statistical power in uncovering novel genetic signals and mechanisms of neurodegeneration. We analysed data from five young and old adult cohorts (MRi-Share, Human Connectome Project, UK Biobank, Generation Scotland Subsample, and Lothian Birth Cohort 1936 [LBC1936]) to test the validity and utility of LBA inferred from cross-sectional MRI data, i.e.
