Chemistry of Evaporating Charged Alcohol Microdroplets in Humid Environments

Abstract There has been recent interest in the physics of evaporating alcohol droplets under humid conditions. These studies focus on delineating time scales for different physical processes, but what about the chemistry? Given the novel reactivity of aqueous microdroplets, we su...

A formal finite-size spectral-map hierarchy for free-fermion entanglement

This record contains the preprint and the complete reproducibility package for “A formal finite-size spectral-map hierarchy for free-fermion entanglement”. The work studies the finite-size deformation of the spectral relation between the discrete prolate (Slepian) eigenvalue and...

PFUSRC‑173: Boundary Normalization Mechanism under Extreme Conditions at the 45° Triple Coaxial Bicone Boundary — Matter‑Energy Screening, Transport, Ejection, and Transition Evolution of Celestial Bodies

Based on the 45° triple coaxial bicone global topological system, this paper proposes the boundary normalization mechanism. The steady‑state operation of triple coaxial bicone‑configuration celestial bodies requires that the junction boundary between the bicone waist‑ring and con...

Triangle Sums, Peripheral Cycles, and Contractions for Orderable Cographic Matroids

For closed simplicial surface triangulations, this preprint proves a general triangle-rooted gluing theorem for compatible cographic orderings and an exact if-and-only-if criterion for triangle sums. It constructs infinite families of 3-connected regular non-graphic orderable cog...

Synergistic Thermal Rearrangement and In Situ Decarboxylation Crosslinking: Structure Tailoring of Copolyimide Membranes for Enhanced Gas Separation

Abstract To enhance the gas separation performance of polyimide membranes, the synergy of thermal rearrangement (TR) and in situ decarboxylation crosslinking represents a distinctive fabrication strategy. Herein, a diamine monomer functionalized with both carboxyl and hydroxyl gr...

The Significant Push and Pull Factors Responsible for Migration of Africans (JAPA) Syndrome: The Comparative Analyses

This study investigates the endogamous and exogamous variables that represent African migration and the contemporary Nigerian Japa Syndrome. It contends that, beyond the unfavourable economic climate and the lingering security issues, among other internal vices in Africa, especia...

FOR-HEALTH: study protocol for a randomized controlled feasibility trial of Structured Health Dialogues to improve lifestyle habits and metabolic health in forensic psychiatric inpatients

Abstract Background People with severe mental illness demonstrate markedly reduced life expectancy, largely due to preventable cardiometabolic disease. This burden is particularly pronounced in compulsory forensic psychiatric care, where prolonged inpatient stays, restrictive env...

(Short Paper16) Super-Intercellular Synchronization and High Light Adaptation in 4-Cell Green Alga Tetrabaena: A Spatially Extended Quantum Computing Model via a 4-QPU Array

Tetrabaena socialis, a four-celled colonial green alga arranged in a planar square, exhibits hydrodynamically synchronized swimming despite each cell possessing autonomous flagella. Furthermore, unlike related species that execute phototactic avoidance migrations under intense li...

Measurements of Diffusion Coefficients of CO2 in 1-Butanol with a New Laminar Jet Apparatus and PFG-NMR, Pointing to Interfacial Mass Transfer Effects

Abstract A novel laminar jet apparatus (LJA) was constructed for precise gas–liquid mass transfer measurements up to 12 bar, significantly extending the technique’s operating window. It was applied to carbon dioxide +1-butanol between 283 and 333 K. Corresponding measurements wer...

Association between vancomycin trough concentration monitoring and gestational age in neonates: a single-center, retrospective observational study

Abstract Background The vancomycin dosing regimen for neonates is primarily determined by gestational age (GA) and postnatal age(PNA). Nonetheless, initial trough concentrations frequently fall below therapeutic levels in neonates administered vancomycin. This study seeks to exam...

Controllable Reconstruction of the Ni/MgAl2O4 Catalyst by In Situ Liquid-Phase Reduction Combined with an Adsorption-Impregnation Strategy to Enhance Reaction Performance for MCH Steam Reforming

Abstract Hydrogen production via catalytic steam reforming of high-carbon hydrocarbons, with low cost, strong adaptability, and easy industrialization, is one of the core technologies for addressing the hydrogen supply bottleneck of fuel cells. However, traditional synthesis meth...

The 1H, 15N and 13C backbone resonance assignments of an intrinsically disordered region (467–696) of breast cancer type 1 susceptibility protein (BRCA1)

The tumor suppressor protein breast cancer type 1 susceptibility protein (BRCA1) plays a central role in maintaining genome stability through its involvement in DNA damage repair, transcriptional regulation, and cell-cycle control. BRCA1 functions as an obligate heterodimer with...

Identification and observed changes in the rainy season onset and termination in Central Chile

The onset and termination of the rainy season shape the planning and operation of water resources systems. Thus, we identify the onset and termination in Central Chile (32–40°S) from 1960 to 2021 based on the occurrence of frequent wet spells (consecutive days with rainfall ≥1 mm...

Incidence and risks of adverse fetal and neonatal outcomes in the LABOR study, a prospective intrapartum cohort in four tertiary referral centers in Ghana, India, and Zambia

Abstract Background Globally, more than two million perinatal deaths occur annually attributable to the intrapartum period, the vast majority occurring in low- and middle-income countries (LMICs). We sought to ascertain the incidence of adverse neonatal intrapartum-related outcom...

A poorly known deep sea skate under pressure: first biological observations of the data-deficient travancore skate (Dipturus johannisdavisi)

Context Dipturus johannisdavisi is a little known deep-sea skate from the Indian Ocean, with limited biological information and a Data Deficient IUCN listing. Aim This study provides baseline information on size structure, life-history traits, diet, and fishery interactions to su...

Abstract This study examines the factors associated with corporate social responsibility (CSR) disclosure and green tourism practices among tourism enterprises in Vietnam. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the study analyzes survey data collected...

How Later SEC Comparatives Leak Into Historical Backtests: A CoreWeave Case Study

This reproducible case study examines how later SEC comparative values can leak into an earlier historical backtest when a financial-data warehouse destructively retains only the latest value for each issuer, taxonomy concept, unit and fiscal period. The study matches 14 CoreWeav...
