Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Influence of Atmospheric Slant Path on Geostationary Hyperspectral Infrared Sounder Radiance Simulations

Geophysical Research Letters
Accurately simulating a geostationary hyperspectral infrared sounder is critical for quantitative applications. Traditional radiation simulations of such instruments often overlook the influence of slant observation geometry by using vertical profile ...

TIR-MS: Thermal Infrared Mean-Shift for Robust Pedestrian Head Tracking in Dynamic Target and Background Variations

Applied Sciences, 2019
Thermal infrared (TIR) pedestrian tracking is one of the major issues in computer vision. Mean-shift is a powerful and versatile non-parametric iterative algorithm for finding local maxima in probability distributions. In existing infrared data, and mean-

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Effects of chromaticity difference from Planckian locus duv of lighting on tinted color of illumination and brightness in space (part 1): Experiment using a scale model with uniform luminance distribution

Japan Architectural Review, 2022
The purpose of this study was to identify the combined effects of illuminance, correlated color temperature, and chromaticity shift from the Planckian locus duv on the perception of the tinted color of illumination and spatial brightness.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Brightness enhancement limits in pulsed cladding pumped fiber Raman amplifiers

We analyze theoretically limitations on the brightness enhancement of a multimode pump beam, to be efficiently converted into a diffraction-limited Stokes beam in a cladding-pumped fiber Raman amplifier.

Enhancing Passive Microwave Brightness Temperature Using Dual-Attention SRGAN

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study presents a dual-attention super-resolution generative adversarial network (DA-SRGAN) framework to enhance the spatial resolution of passive microwave (PMW) brightness temperature (TB) data from 12.5/25 km to 3.125/6.25 km.

Solar brightness temperature at submillimeter wavelengths

The Astrophysical Journal, 1987
Solar brightness temperature data obtained at 34.9 km during a balloon flight from the Canadian Space Research Facility on August 28, 1982 are analyzed. A servocontrolled telescope capable of solar image scanning, a Michelson interferometer with 0.015/cm apodized resolution, and an in-flight radiometric calibration source were used to obtain the ...
