Data-Driven Methodologies For Pressure Probe Calibration: Integrating Symbolic Regression With Gaussian Process Regression

Abstract This study presents a unified data-driven calibration framework for five-hole pressure probes that combines symbolic regression with Gaussian process regression to improve accuracy, generalization, and interpretability across low-subsonic operating conditions (0.05 ≥ Ma...

Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO 3

ABSTRACT Epitaxial strain is a powerful means to engineer emergent phenomena in thin films and heterostructures. Here, we demonstrate that , a cubic perovskite in bulk form, can be epitaxially strained into a highly tunable ferroelectric. films grown commensurate to (001) substra...

Small Business Judging Judges

We find that shifts toward more liberal (i.e., less probusiness) courts predict reductions in local small business activity. A one-standard-deviation increase in liberal ideology predicts a 1% reduction in firm count relative to bordering counties in different federal court juris...

Control of PhotoinducedLigand Detachment from QuantumDot Surfaces Using Nanocrystal Architecture

Abstract We investigated the influence that nanocrystal architecture has on the extent to which colloidal quantum dots undergo photoinduced ligand detachment. We took advantage of the ability of electrons to delocalize throughout both the core and shell of CdSe/CdS core/shell nan...

Hepatocyte-intrinsic ER stress and NRF2 initiate primary sclerosing cholangitis, providing therapeutic insights

primary sclerosing cholangitis (PSC) is a severe liver disease that can progress to cholangiocarcinoma. Therapeutic development has been hindered by the rarity of PSC and by its poorly understood origin, which reflects incompletely defined genetic and environmental risk factors....

The Impact of Writing Instruction for English Language Learners in the United States: A Meta-Analysis

Abstract Writing is a cornerstone of academic success, yet English language learners (ELL) in the United States must learn to write while also developing English proficiency. Although descriptive reviews suggest that writing instruction can benefit these learners, no prior meta-a...

Defect Landscapeand Stability of High-Entropy Carbides

Abstract High-entropy carbides (HECs) can be stabilized as single-phase solid-solution microstructures by kinetically trapping a “high-entropy state” under ambient conditions; however, such microstructures may represent metastable states rather than true thermodynamic equilibrium...

Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

ABSTRACT Wearable and flexible optoelectronic devices are rapidly advancing toward human‐interactive applications. However, their operational lifespan is often limited by mechanical damage, interface delamination, and environmental influences. Existing encapsulation methods provi...

Chemical Characterization and Bioactive Profile of a Selection of 45 Rapini Populations

The present study evaluated the chemical profiles and bioactivities of 45 rapini (Brassica rapa L.) populations (RA1-RA45) cultivated in Central Greece. Our results suggest that the tested rapini populations differed in their compositional traits, with coefficients of variation (...

Exploring the role of place visitation big data on small area health measure estimation

Population-level health measures at small geographic scales (e.g., census tracts), including health conditions, preventive behaviors, risk factors, and overall health status, are crucial for guiding effective health planning and policymaking. It has been well established that dem...

Association between urbanicity–cooking fuel type and self-reported respiratory symptoms as a proxy for acute respiratory infection symptoms among children under two years across ten East African countries

Abstract Introduction Evidence remains limited on how urbanicity modifies the relationship between household cooking fuel type and respiratory symptoms in young children in low- and middle-income countries (LMICs). This study examined the prevalence of cough and dyspnea across te...

Insights from Explainable AI-Assisted Microbial SourceTracking in an Urban Watershed

Abstract Microbial contamination in urban watersheds poses significant challenges for public health, yet traditional monitoring offers limited insight into identifying contamination sources or environmental drivers. This study integrates chip-based digital polymerase chain reacti...

A Curvature-Corrected Wall Model for Axisymmetric Turbulent Boundary Layers

Abstract In wall-modeled large-eddy simulation (WMLES), the velocity is sampled at a distance from the wall in the turbulence resolving region. Then, using this velocity as a boundary condition, Reynolds-averaged Navier-Stokes equations in thin boundary-layer form are solved down...

Ribosomal protein bL27 protects translating ribosomes from tmRNA-SmpB

Bacterial ribosomal protein bL27 is universally conserved, and its amino terminus is adjacent to the peptidyl transfer center, yet its roles in translation remain unclear. Combining genetics, biochemistry, and molecular dynamics, we show that bL27 has an unexpected role in preven...

PKU: Sentenced to a Restricted Diet?

<p><strong>Abstract</strong>: <br /> This case explores the reasons for why a healthy infant at birth starts to have cognitive deficiencies soon after birth. Early intervention by prenatal screening can be implemented to prevent these deficiencies...

Unraveling the Ionic Adsorption and Migration Mechanism of Inverse Opal Capacitive Deionization Electrode

ABSTRACT Developing advanced capacitive deionization electrodes for desalination requires the concurrent enhancement of thermodynamic and kinetic properties. Despite extensive research on improving thermodynamic features represented by adsorption capacity, the investigation on th...

An exact approach for describing adsorption and catalysis of interacting species in lattice models

Lattice models provide a useful framework for studying the adsorption and catalysis of interacting species. For such systems, the mean-field and quasi-chemical approximations are widely used. At equilibrium, full enumeration of the grand-canonical partition function would allow f...

Seizures are associated with cognitive disengagement syndrome, incoordination, and low IQ in child ADHD and autism samples

This is the first study comparing children with and without seizures in a large clinical sample and examining differences in diagnoses, IQ, neuropsychological and achievement test scores, and psychological problems. Mothers rated 2,212 children (4-17 years) with autism and/or ADH...

A Cigarette Tax and Childcare Mitigate Nicotine Exposure in Young Children

OBJECTIVES The detrimental effects of tobacco smoke on children’s health are well known. Although evidence suggests that cigarette excise taxes can reduce adult smoking, it remains unclear whether they reduce the nicotine levels of infants and toddlers—a developmentally vulnerabl...

Shifting Futures: Trends in Socioeconomic Disparities in Adolescents’ Expected Occupational Status in the United States and the United Kingdom, 2000–2018

Using data from the Programme for International Student Assessment 2000–2018, this study examined trends in adolescents’ expected occupational status, socioeconomic status (SES) gradients, and distributional SES differentials in the United States and the United Kingdom. Guided by...
