High Energy Cosmic Rays From Supernovae [PDF]

, 2016
Cosmic rays are charged relativistic particles that reach the Earth with extremely high energies, providing striking evidence of the existence of effective accelerators in the Universe. Below an energy around $\sim 10^{17}$ eV cosmic rays are believed to

PESC -- Parallel Experiment for Sequential Code

CoRR, 2023
The need for computational resources grows as computational algorithms gain popularity in different sectors of the scientific community. This search has stimulated the development of several cloud platforms that abstract the complexity of computational infrastructure.

Analysis of Human Uniparental Embryonic Stem Cells Reveals New Putative Imprinted Loci

Cell Proliferation, EarlyView.
To identify novel imprinted genes, parthenogenetic, androgenetic and biparental human embryonic stem cells and their differentiated neural progenitors were analysed by methylome and transcriptome profiling. This approach uncovered 12 putative novel imprinted genes, including a clustered region on chromosome 19, expanding the current catalogue of ...

Purification Effect of PES-C Ultrafiltration Membrane Incorporated with Emodin on Acanthopanax Senticosus Injection

Pharmaceuticals, 2023
A new PES-C/emodin ultrafiltration membrane was prepared by blending natural emodin with phenolphthalein polyethersulfone (PES-C) and was used to purify an acanthopanax senticosus injection in this study.

Inverse-square law between time and amplitude for crossing tipping thresholds [PDF]

, 2019
A classical scenario for tipping is that a dynamical system experiences a slow parameter drift across a fold tipping point, caused by a run-away positive feedback loop. We study what happens if one turns around after one has crossed the threshold.

Mitochondrial respiratory capacities are not linked to individual variation in hypoxia tolerance and standard metabolic rate in European seabass Dicentrarchus labrax

Journal of Fish Biology, EarlyView.
Abstract In hypoxic environments, fish attempt to regulate their metabolic rate as oxygen levels in the water decline. Individuals that have low energy requirements for maintenance – standard metabolic rate (SMR) – are expected to have higher hypoxia tolerance, measured as the critical water oxygen saturation threshold (Scrit) below which they cannot ...

On the photoelectric quantum yield of small dust particles

, 2016
Photoelectron emission is crucial to electric charging of dust particles around main-sequence stars and gas heating in various dusty environments. An estimate of the photoelectric processes contains an ill-defined parameter called the photoelectric ...

Identification and Functional Characterization of Isoflavone synthase Gene Family in Pea (Pisum sativum): The Entry Point to Pisatin Biosynthesis

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Isoflavone synthase (IFS), a cytochrome P450 monooxygenase of the CYP93C subfamily, catalyzes the conversion of flavanones into isoflavones, the first committed step in the biosynthesis of isoflavonoid phytoalexins. In pea (Pisum sativum L.), the phytoalexin pisatin plays a pivotal role in defense against pathogens.

Mexican Freshwater Fish: Identifying Conservation Priorities and High‐Risk Areas for Fisheries Under Climate Change

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Freshwater fish are essential components of aquatic ecosystems, providing key ecological functions and supporting livelihoods. Climate change poses a significant threat to freshwater biodiversity; consequently, both its conservation and the food security it sustains may be at risk.

AGN Dusty Tori: II. Observational Implications of Clumpiness [PDF]

, 2008
From extensive radiative transfer calculations we find that clumpy torus models with \No \about 5--15 dusty clouds along radial equatorial rays successfully explain AGN infrared observations.
