Extraction of electromagnetic neutron form factors through inclusive and exclusive polarized electron scattering on polarized 3He target [PDF]

open access: yes, 2000
Inclusive 3He(e,e') and exclusive 3He(e,e'n) processes with polarized electrons and 3He have been theoretically analyzed and values for the magnetic and electric neutron form factors have been extracted.

Economic Shocks and Trade Policy: Analyzing Household Food Insecurity in Nigeria Following the 2015 Oil Price Decline

open access: yesFood and Energy Security, Volume 15, Issue 1, January/February 2026.
ABSTRACT This study investigates the dynamics of household food insecurity in Nigeria using panel data from three waves (2012, 2015, and 2018) of the General Household Survey, situating micro‐level evidence within the broader macroeconomic context.

Fundamental relation between longitudinal and transverse conductivities in the quantum Hall system

open access: yes, 2009
We investigate the relation between the diagonal ($\sigma_{xx}$) and off-diagonal ($\sigma_{xy}$) components of the conductivity tensor in the quantum Hall system.

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

The influence of electron temperature on pattern-dependent charging during etching in high-density plasmas [PDF]

open access: yes, 1997
The effect of the electron temperature (Te) on charging potentials that develop in trenches during plasma etching of high aspect ratio polysilicon-on-insulator structures is studied by two-dimensional Monte Carlo simulations.

Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View

open access: yesAdvanced Photonics Research, Volume 6, Issue 11, November 2025.
Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

Longitudinal Trends, Inequalities, and Progress Towards Achieving Food Security Across Bangladesh

open access: yesWorld Food Policy, Volume 11, Issue 2, November 2025.
ABSTRACT Food insecurity remains a persistent global challenge, particularly in Global South countries such as Bangladesh. Despite being a long‐standing policy priority, no study has explored the longitudinal trends and inequalities of food security across Bangladesh.

The Saskatchewan Indian Gaming Authority’s Approach To Securing Public Trust, 2000–2004

open access: yesJournal of Aboriginal Economic Development, 2010
The effects of the SIGA scandal, or the "Dutch Lerat Affair," as it was branded, led many to publicly question SIGA's accountability, which potentially undermined its corporate image. Since a corporation's image is the link between corporate reality and

Physiological aspects of adaptation of cadets of academy FSIN of Russia to physical activities

open access: yesI.P. Pavlov Russian Medical Biological Herald, 2011
In this article some aspects of adaptation to physical activities of cadets of Academy FSIN of Russia are considered. 98 cadets with high (48 cadets) and low (50 cadets) success of physical training have been surveyed. In order to analyze the heart rate variability a complex "Varicard" and ISKIM-6 software have been used. Results of research specify in

Analyticity and uniform stability of the inverse singular Sturm--Liouville spectral problem [PDF]

open access: yes, 2011
We prove that the potential of a Sturm--Liouville operator depends analytically and Lipschitz continuously on the spectral data (two spectra or one spectrum and the corresponding norming constants).
