Matched Guiding and Controlled Injection in Dark-Current-Free, 10-GeV-Class, Channel-Guided Laser-Plasma Accelerators.

We measure the high-intensity laser propagation throughout meter-scale, channel-guided laser-plasma accelerators by adjusting the length of the plasma channel on a shot-by-shot basis, showing high-quality guiding of 500 TW laser pulses over 30 cm in a hydrogen plasma of density n_{0}≈1×10^{17}  cm^{-3}. We observed transverse energy transport of higher-order modes in the first ≈12  cm of the plasma channel, followed by quasimatched propagation, and the gradual, dark-current-free depletion of laser energy to the wake. We quantify the laser-to-wake transfer efficiency limitations of currently available petawatt-class lasers and demonstrate via simulation how control over the laser mode can significantly improve beam parameters.

Quantum Thermodynamics of Nonequilibrium Processes in Lattice Gauge Theories.

A key objective in nuclear and high-energy physics is to describe nonequilibrium dynamics of matter, e.g., in the early Universe and in particle colliders, starting from the standard model of particle physics.

Measurement of CP Violation Observables in D^{+}→K^{-}K^{+}π^{+} Decays.

A search for violation of the charge-parity (CP) symmetry in the D^{+}→K^{-}K^{+}π^{+} decay is presented, with proton-proton collision data corresponding to an integrated luminosity of 5.4  fb^{-1}, collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the D^{+} and D^{-} phase-space distributions, with instrumental asymmetries subtracted using the D_{s}^{+}→K^{-}K^{+}π^{+} decay as a control channel.

The gap between surgeon goal and achieved sagittal alignment in adult cervical spine deformity surgery.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

Investigation of Natural Dyes and Taxonomic Identification of Fibers Used in Chancay Textiles by Vibrational Spectroscopy and Mass Spectrometry.

Textiles provide a valuable source of information regarding past cultures and their artistic practices. Understanding ancient textiles requires identifying the raw materials used, since the origin of dyes and fibers may be from plants or animals, with the specific species used varying based on geography, trade routes and cultural significance. A selection of nine Chancay textile fragments attributed to 800-1200 CE were studied with liquid chromatography mass spectrometry (LC-MS) and direct analysis in real time mass spectrometry (DART-MS) to identify the chemical compounds in extracts of natural dyes used to create green, blue, red, yellow and black colors.

NIST Mass Spectral Libraries in the Context of the Circular Economy of Plastics.

The Mass Spectrometry Data Center (MSDC) has recently started improving existing libraries and creating new ones for identifying and analyzing plastics-related compounds (PRC) and materials (PRM) as part of the NIST circular economy program. PRC are small molecules of dissimilar chemical nature; hence, to increase coverage, we have used three types of ionizations: EI, ESI, and APCI. PRM are solids that include polymers, polymer mixtures, and commercial plastics, so we have used pyrolysis-gas chromatography (py-GC-MS) to create a new searchable library.

Metagenomic Sequencing of Tomato Plants with Wilt Symptoms Allows for Strain-Level Pathogen Identification and Genome-Based Characterization.

Diseases that affect the vascular system or the pith are of great economic impact since they can rapidly destroy the affected plants, leading to complete loss in production. Fast and precise identification is thus important to inform containment and management, but many identification methods are slow because they are culture-dependent and they do not reach strain resolution. Here we used culture-independent long-read metagenomic sequencing of DNA extracted directly from stems of two tomato samples that displayed wilt symptoms.

Technical and management coaching for government institutions: Lessons learned and health systems transformations across 8 countries in sub-Saharan Africa and India.

Traditional engagement with local governments often relies on financial and human resources from international or local partners, leading to direct implementation by organizations, which can hinder sustainability. While some organizations include sustainability indicators, few focus on transferring technical and financial ownership to governments. The Challenge Initiative (TCI) uses a phased coaching model-lead, assist, observe, and monitor-to build local government capacity for scaling family planning (FP) and adolescent and youth sexual and reproductive health (AYSRH) programs.

Symbolic dynamics of joint brain states during dyadic coordination.

We propose a novel approach to investigate the brain mechanisms that support coordination of behavior between individuals. Brain states in single individuals defined by the patterns of functional connectivity between brain regions are used to create joint symbolic representations of brain states in two or more individuals to investigate symbolic dynamics that are related to interactive behaviors. We apply this approach to electroencephalographic data from pairs of subjects engaged in two different modes of finger-tapping coordination tasks (synchronization and syncopation) under different interaction conditions (uncoupled, leader-follower, and mutual) to explore the neural mechanisms of multi-person motor coordination.

Digital Health Technology Research Funded by the National Institutes of Health.

Importance: Digital health in biomedical research and its expanding list of potential clinical applications are rapidly evolving. A combination of new digital health technologies (DHTs), novel uses of existing DHTs through artificial intelligence- and machine learning-based algorithms, and improved integration and analysis of data from multiple sources has enabled broader use and delivery of these tools for research and health care purposes. The aim of this study was to assess the growth and overall trajectory of DHT funding through a National Institutes of Health (NIH)-wide grant portfolio analysis.

Prevalence Estimation Methods for Time-Dependent Antibody Kinetics of Infected and Vaccinated Individuals: A Markov Chain Approach.

Immune events such as infection, vaccination, and a combination of the two result in distinct time-dependent antibody responses in affected individuals. These responses and event prevalence combine non-trivially to govern antibody levels sampled from a population. Time-dependence and disease prevalence pose considerable modeling challenges that need to be addressed to provide a rigorous mathematical underpinning of the underlying biology.

Basic Science and Pathogenesis.

Background: Age, sex, and APOE genotype are well-established risk factors for late-onset Alzheimer's Disease (LOAD). Previous findings demonstrate that neuroinflammatory profiles of the human midlife female brain closely resemble the human AD brain. Given APOE's role in LOAD pathogenesis, here we investigate the contribution of this risk factor on targeted AD relevant transcriptional pathways.

Basic Science and Pathogenesis.

Background: Inflammation plays a pivotal role in driving the development and progression of Alzheimer's disease (AD) in the human brain, offering a promising avenue for therapeutic intervention. However, the initiation phase of inflammation and its potential sex differences remain elusive. In this study, we aim to provide translational validity to our preclinical findings by testing two hypotheses: 1) the inflammatory profile of late-onset AD (LOAD) is initiated and detectable during midlife aging, and 2) sex differences manifest in the brain by midlife.

Clinical Manifestations.

Background: How clinicians discuss, document, and diagnose health concerns within a visit shapes patient perceptions of their health conditions. Undiagnosed hearing loss among older adults with dementia or cognitive concerns may exacerbate neuropsychiatric symptoms and care challenges. This study investigates clinician documentation of hearing concerns and whether documentation, diagnosis, and referral vary for older adults with dementia/cognitive concerns.
