Multipole polarizability of a graded spherical particle [PDF]

open access: yes, 2005
We have studied the multipole polarizability of a graded spherical particle in a nonuniform electric field, in which the conductivity can vary radially inside the particle.

How Pre‐Pregnancy Weight and Polycystic Ovary Syndrome Impact Pregnancy Outcomes: A Population‐Based Cohort Study

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Pre‐pregnancy overweight/obese status among women with polycystic ovary syndrome (PCOS) could increase the risk of at least one adverse pregnancy outcome (APO). This study aimed to determine how pre‐pregnancy weight and PCOS impact pregnancy outcomes. Methods For the current study, we used data collected in the Tehran Lipid

Moderators of Organic Matter Decomposition in Portuguese Streams: A Field Study and Literature Review

open access: yesFreshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Organic matter decomposition is a fundamental ecosystem process in streams, which have a large aquatic‐terrestrial interface. The sensitivity of organic matter decomposition to changes in environmental conditions promoted by human activities is relatively well understood at large and local scales.

Measuring Electric Fields From Surface Contaminants with Neutral Atoms [PDF]

open access: yes, 2007
In this paper we demonstrate a technique of utilizing magnetically trapped neutral Rb-87 atoms to measure the magnitude and direction of stray electric fields emanating from surface contaminants.

Integrative Omics Defines Metabolic Biomarkers and Genetic Regulatory Mechanisms of Mortality Risk

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Understanding mortality mechanisms remains a fundamental challenge. Through multi‐omics analysis of a three‐generation chicken model, are identified 45,585 mQTLs and establish a 16‐metabolite predictor of mortality. An inflammation‐growth trade‐off and evolutionarily conserved pathways involving butyrate–microbiota interactions and L‐cysteine's dual ...

Nonlinear dynamics of the interface of dielectric liquids in a strong electric field: Reduced equations of motion

open access: yes, 2005
The evolution of the interface between two ideal dielectric liquids in a strong vertical electric field is studied. It is found that a particular flow regime, for which the velocity potential and the electric field potential are linearly dependent ...

Machine Learning‐Guided Repositioning of a SARS‐CoV‐2‐Targeting Molecular Series as Cruzain Inhibitors

open access: yesChemMedChem, Volume 21, Issue 2, January 2026.
An ExtraTrees machine learning (ML) model is used to reposition a SARS‐CoV‐2‐directed library of peptidomimetic compounds as cruzain inhibitors for Chagas disease. Potent binders with a novel P1 moiety (for cruzain) are identified and validated by calorimetry.

Spontaneous chirality via long-range electrostatic forces

open access: yes, 2007
We consider a model for periodic patterns of charges constrained over a cylindrical surface. In particular we focus on patterns of chiral helices, achiral rings or vertical lamellae, with the constraint of global electroneutrality.

Comparison of various fertilizer recommendations for forage crops in the Western United States

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract Farmers often use private and public labs, crop advisors, or fertilizer dealers to determine fertilizer needs for crops, with recommendations and resulting costs from these sources having the potential to vary greatly. Twelve on‐farm trials across the state of Utah in alfalfa (Medicago sativa), small grain forage, and silage corn (Zea mays ...

Relating localized nanoparticle resonances to an associated antenna problem

open access: yes, 2010
We conceptually unify the description of resonances existing at metallic nanoparticles and optical nanowire antennas. To this end the nanoantenna is treated as a Fabry-Perot resonator with arbitrary semi-nanoparticles forming the terminations.
