Improving grain yield prediction in Southern US oat germplasm using genomics information and environmental covariates

Genetic gains of oat (Avena sativa L.) grain yield have been historically low compared to other major cereal crops. The use of machine learning models to capture complex interactions and leveraging data types other than genomic information in prediction models has great potential...

Synthetic Studies toward Anguidine: Assembly of the Tricyclic Ether Scaffold

Anguidine, a type A trichothecene (TCN) isolated from Fusarium graminearum, features a highly functionalized 6/6/5 tricyclic scaffold incorporating a central six-membered ether ring and a C12–C13 epoxide. Its pronounced bioactivity and structural complexity render it a challengin...

Monotonicity-constrained physics-informed neural networks for concrete compressive strength prediction

Abstract Accurate prediction of concrete compressive strength is critical for mix design optimization, quality control, and reliable decision-making in modern construction. While data-driven machine learning models have demonstrated strong predictive capability, most existing app...

Flash Communication: Lithium 1,4-Diazine Triple Ion Radical Complexes─Structural Isolation and Trends in Spin Delocalization

Abstract A series of dilithium 1,4-diazine radical anion complexes were synthesized as analogs to alkali triple ion radical complexes. The solid-state structures display bond metrics consistent with single-electron reduction of the bridged diazine. EPR analysis shows diazine-loca...

Modest Changes in Extracellular pH Impose Metabolic and Envelope Remodeling in Burkholderia thailandensis

ABSTRACT Burkholderia thailandensis is a commonly used surrogate for pathogenic Burkholderia species, yet how it adapts to changes in extracellular pH remains poorly characterized. Using quantitative mass spectrometry, we report here the relative proteomes for cells exposed to a...

Libraries, research and development funding, and economic prosperity: data for the holistic university

Abstract Macro indicators of Research and Development (R&D) such as numbers of journal publications and citation rates, patents, impact factors, and R&D expenditures have become proxies for economic competitiveness. But quantifying relationships between macro-indicators and budge...

SEMIINFINITE SHEAVES ON AFFINE FLAG VARIETIES

Abstract We study a category of semiinfinite sheaves on the affine flag variety of a connected reductive algebraic group G , with coefficients in a field k $\Bbbk $ double struck k (of arbitrary characteristic different from that of the base field), generalizing some results of G...

Evaluating the Use of a Backward Chaining Procedure to Teach Young Autistic Children Multiple Step Requesting Using AAC

Abstract This study evaluated the use of a time delay with a least-to-most prompting hierarchy and backward chaining, in the acquisition of a multi-step mand sequence for three young autistic children, who also use an augmentative and alternative communication (AAC) system. The A...

In the Shadow of Smoke and Silence: Understanding Cancer Awareness and Healthcare-Seeking Behavior in Louisiana’s Cancer Alley

Background/Objectives: Louisiana’s industrial corridor, commonly known as “Cancer Alley,” has been extensively documented as a site of environmental and health inequity. Less is known about how residents understand cancer risk, identify available cancer care, and make decisions a...

Visualizing Metabolism: Lipid-Based Raman Nanoreporters as an Enabling Platform for Metabolic Imaging and Precision Medicine

Abstract Lipid-based Raman reporters represent a promising but still developing class of metabolic sensors. This review reports lipid nanoparticles and lipid conjugated inorganic nanoparticles as Raman-active systems capable of decoding cellular metabolism with spatial and chemic...

Rapid data quality investigations of gravitational-wave events with the Data Quality Report Builder toolkit

Abstract We present the Data Quality Report Builder toolkit, DQRbuild, a suite of data quality tools that have been developed to vet gravitational-wave events in preparation for the fourth LIGO-Virgo-KAGRA observing run. We explain the main functionality and the many scientific t...

Molecular based diagnostic testing for urinary tract infections: the results remain unclear

INTRODUCTION: Recent advances have led to a rise in metagenomic and molecular-based testing for more rapid diagnosis of urinary tract infections (UTI). We conducted a contemporary systematic review to understand how these molecular tests affect clinical outcomes. METHODS: A syste...

Altermagnetic spin textures: Emergent electrodynamics, quantum geometry, and probes

Emergent electrodynamics arising from spatially and temporally varying magnetic textures provides a framework for spin control in quantum materials. While this principle is established for ferromagnetic and antiferromagnetic textures, its consequences for altermagnets—magnetic or...

Five-expert PDE: lean formalization

Lean formalization for the explicit solution of the 5-expert PDE.

Microtidal wetland losses and hydrologic stressors as sea level rise accelerates in the Gulf of Mexico: running with Alice

Abstract Global sea level rise (SLR) is a widely appreciated threat to coastal wetlands. Modeled estimates of SLR thresholds beyond which coastal wetlands convert to open water suggest that landscape scale estimates of wetland loss vary with geomorphic setting, upland barriers to...

Conference Goals And Learning Preferences Among Attendees at A National Surgical Meeting

Objective This study evaluated differences in conference goals and preferred learning modalities across demographic groups at a national surgical conference. Design An optional online survey collected demographic information (gender, practice type, role, years in independent prac...

Reconfigurable structural color generation in multicolor pixels using phase-change materials

We introduce multilayer structures based on phase-change materials for reconfigurable structural color generation. These structures can produce multiple distinct colors within a single pixel. Specifically, we design structures that generate either two or four maximally distinct s...

Increasing nitrogen loading in the Gulf of Mexico undermines coral reef resilience

The ongoing global decline of coral reefs underscores the need to identify key mechanisms driving reef deterioration. The Flower Garden Banks (FGB) reefs in the northern Gulf are widely regarded as some of the healthiest in the continental United States, but recent disease outbre...

Transing the archive: Toward a trans‐autistic historiography of neurodivergent futures

This article advances transing the archive as a methodological intervention into how autism's canonical history became institutionally secured through archival processes operating within clinical and bureaucratic regimes, not simply through omission. Drawing on archival and digit...

ACE2 downregulation contributes to adverse cardiovascular and reproductive outcomes in female mice on high fat diet

Obesity is a growing concern among women of reproductive age, as it can significantly impact both maternal and fetal health. A potential mechanism linking obesity to cardiometabolic dysfunction is the imbalance between the classical (pressor) and the compensatory (protective) arm...
