Loss of DET1 in High Pigment 2 Tomato Prevents High Temperature Repression of Anthocyanin Biosynthesis in Fruit Through HY5 Stabilization

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming impacts several aspects of plant physiology, with important negative effects on crop yield and production of secondary metabolites, such as anthocyanins. The anthocyanin content of vegetables and fruits has attracted public interest in the last two decades due to its health benefits, leading to the development of novel ...

What Does “STEM” Mean to Students? Exploring the Interplay Between Self‐Efficacy, Extracurricular Activities, Subject Associations, and Academic Intentions in Secondary School

School Science and Mathematics, EarlyView.
ABSTRACT Despite extensive discourse in educational research and practice, inconsistencies persist in students' perception of, and engagement with, STEM subjects. This study investigates how secondary school students perceive STEM disciplines, and which factors modulate their self‐efficacy and academic intentions. The survey (n = 853) revealed a widely

Distributed Sequential Coalition Formation Algorithm for Spectrum Allocation in Underlay Cognitive Radio Networks

IEEE Access, 2019
In this paper, we study the resource allocation problem, including the joint consideration of user grouping and power allocation, of an, underlay cognitive radio (CR) network employing non-orthogonal multiple access (NOMA), which is referred to as the ...

Low Complexity Iterative Receiver Design for Shallow Water Acoustic Channels

EURASIP Journal on Advances in Signal Processing, 2010
An adaptive iterative receiver structure for the shallow underwater acoustic channel (UAC) is proposed using a decision feedback equalizer (DFE) and employing bit-interleaved coded modulation with iterative decoding (BICM-ID) in conjunction with ...

Analysis of turbo codes with asymmetric modulation

Electronics Letters, 1999
If different energies are assigned to two outputs of a turbo encoder, the information bit and parity bit, then the performance will be changed according to the ratio of the information bit energy to the parity bit energy. The optimum point of the ratio may not be 1. As the rate of the turbo code is changed, the optimum point will also be changed.

Ovarian hormone loss modifies the nucleic acid cargo of circulating extracellular vesicles and skeletal muscle metabolism after acute exercise in rats

Experimental Physiology, EarlyView.
Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.

Gq Signaling in Microglia Triggers Interferon Responses and Improves Outcome After Ischemic Stroke

Glia, Volume 74, Issue 10, October 2026.
Chemogenetic activation of Gq signaling in microglia ahead of ischemic stroke reduces infarct size in mice. Seven days after stroke, Gq‐primed microglia in the penumbra show enhanced interferon responses, altered branching patterns, and reduced phagocytosis.

Five Decades of Hierarchical Modulation and Its Benefits in Relay-Aided Networking

IEEE Access, 2015
Hierarchical modulation (HM), which is also known as layered modulation, has been widely adopted across the telecommunication industry. Its strict backward compatibility with single-layer modems and its low complexity facilitate the seamless upgrading of

Time‐Conditioned Zero‐Shot Self‐Supervised Reconstruction for Accelerated 3D Ultra‐Low‐Field MRI

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1303-1312, September 2026.
ABSTRACT Purpose Ultra‐low‐field (ULF) MRI provides a cost‐effective, portable imaging option but has relatively low SNR and long acquisition times compared to standard clinical scans. This study presents a time‐conditioned zero‐shot self‐supervised learning image reconstruction framework (ULF‐ZS‐SSL) to accelerate 3D‐acquired single‐coil ULF MRI ...

Conformational diversity in poly‐HAMP arrays and its implications for signal transduction

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Prokaryotic transmembrane receptors are built around a helical coiled‐coil backbone, with sensory, modulatory, and effector domains arranged along its length. The modulatory HAMP domain forms a parallel four‐helix coiled coil integrated into this backbone, typically connecting transmembrane segments with downstream cytosolic domains.
