Contrasting response of biomass and grain yield to severe drought in Cappelle Desprez and Plainsman V wheat cultivars [PDF]

PeerJ, 2016
We report a case study of natural variations and correlations of some photosynthetic parameters, green biomass and grain yield in Cappelle Desprez and Plainsman V winter wheat (Triticum aestivum L.) cultivars, which are classified as being drought ...

GEANT4 Study of Secondary Electron Emission in ZnO Nanorod Arrays under 10-100 MeV Oxygen Ion Irradiation

Фізика і хімія твердого тіла
Computational study of secondary electron emission (SEE) from ZnO nanorod arrays deposited on Au/Si₃N₄ substrates under irradiation with 16O ions in the 10–100 MeV energy range was performed. Using a combination of SRIM and GEANT4 Monte Carlo simulations,

Secondary electron emission from insulators and negative electron affinity semiconductors

Results in Physics, 2021
Based on expression of primary range R and the R at Epo ≥ 10.0 keV and L at Epo ≥ 1.0 keV calculated by ESTAR program [1], the method of obtaining formula for R at Epo ≥ 1.0 keV is presented; where Epo is incident energy of primary electron, and L is the

Modeling realistic dynamics of differential charging of GEO satellites immersed in Maxwellian plasma environments

Fundamental Plasma Physics
Estimation of the time scale of differential charging between adjacent metal–dielectric surfaces on a Geosynchronous Earth Orbit (GEO) satellite is crucial due to its potential to trigger Electrostatic Discharge (ESD) events.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.
