Dissociative ionization cross-sections and the rate coefficients of H2S, OCS, LiH, and SiC

open access: yesAstronomy & Astrophysics
Context. Electron-molecule and positron-molecule interactions play a major role in the interstellar medium. Although several inelastic channels have been studied in the literature, dissociative ionization studies of molecules are scarce. Aims.

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

open access: yesFEBS 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.

Exact G-functions for various leaf normal distribution functions applied to analytical two-stream radiative transport in turbid vegetation media [PDF]

open access: yes, 2008
In the radiative transfer theory for turbid vegetation media one defines leaf normal distribution (LND) functions to describe the orientation of the model leaves’ normal vectors. For simulation purposes, standard LNDs are frequently assumed, e.g. based

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

A Machine Learning Method for Monte Carlo Calculations of Radiative Processes

open access: yesThe Astrophysical Journal
Radiative processes such as synchrotron radiation and Compton scattering play an important role in astrophysics. Radiative processes are fundamentally stochastic in nature, and the best tools currently used for resolving these processes computationally ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Tungsten Ions in Plasmas: Statistical Theory of Radiative-Collisional Processes

open access: yesAtoms, 2015
The statistical model for calculations of the collisional-radiative processes in plasmas with tungsten impurity was developed. The electron structure of tungsten multielectron ions is considered in terms of both the Thomas-Fermi model and the Brandt ...

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

open access: yesFEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

open access: yesAging and Cancer, EarlyView.
This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Radiative Processes in Cool Star Chromospheres

open access: yesPhysica Scripta, 1984
Observations made with the International Ultraviolet Explorer (IUE) satellite between 1200 A and 3000 A have shown that the spectra of giant and supergiant stars later than about K O are dominated by emission from neutral atoms and singly charged ions.
