Atmospheric Modulation Transfer Function Calculation and Error Evaluation for the Panchromatic Band of the Gaofen-2 Satellite

open access: yesRemote Sensing
In the optical satellite on-orbit imaging quality estimation system, the calculation of Modulation Transfer Function (MTF) is not fully standardized, and the influence of atmosphere is often simplified, making it difficult to obtain completely consistent

“It's My Dark Secret”: A Qualitative Study on the Abortion Experiences of US Active‐Duty Servicewomen

open access: yesPerspectives on Sexual and Reproductive Health, EarlyView.
ABSTRACT Introduction The Hyde Amendment limits US military abortion care and coverage for active‐duty servicewomen (ADSW). ADSW face numerous barriers to care when seeking an abortion. The purpose of this study was to explore the lived experiences of US servicewomen who had an abortion while serving on active duty.

Multiple-true-false questions reveal more thoroughly the complexity of student thinking than multiple-choice questions: a Bayesian item response model comparison

open access: yesInternational Journal of STEM Education, 2019
Background Within undergraduate science courses, instructors often assess student thinking using closed-ended question formats, such as multiple-choice (MC) and multiple-true-false (MTF), where students provide answers with respect to predetermined ...

A Multiscale Factorization Method for Simulating Mesoscopic Systems with Atomic Precision

open access: yes, 2013
Mesoscopic $N-$atom systems derive their structural and dynamical properties from processes coupled across multiple scales in space and time. An efficient method for understanding these systems in the friction dominated regime from the underlying N-atom ...

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1179-1191, June 2026.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

A Cross‐Disease Microglial Transcriptional Program Characterizes Neurodegeneration and Highlights SPP1 as a Biomarker

open access: yesGlia, Volume 74, Issue 6, June 2026.
Distinct microglial subpopulations are depicted, highlighting variations in gene expression and functional roles in response to specific disease conditions and the complexity of microglial activation and differentiation in neurodegeneration. ABSTRACT Microglial cells are key players in maintaining brain homeostasis and responding to pathological ...

Loss of qE Does Not Necessarily Lead to Photoinhibition: Sustained Non‐Photochemical Quenching in the Absence of PsbS and Zeaxanthin

open access: yesPlant, Cell &Environment, Volume 49, Issue 6, Page 3405-3425, June 2026.
ABSTRACT Photosynthetic light‐harvesting complexes mediate light absorption and energy dissipation. By modulating the photosystems' absorption cross‐section, they affect both photosynthetic activity and non‐photochemical quenching (NPQ). These processes are often studied by spectrally integrated chlorophyll fluorescence, masking their associated ...
