Cosmic ray moderation of the thermal instability [PDF]

, 2004
We apply the Hermite-Bieler theorem in the analysis of the effect of cosmic rays on the thermal stability of an initially uniform, static background. The cosmic rays were treated in a fluid approximation and the diffusion coefficient was assumed to be ...

Development of Raman Spectroscopy and Machine Learning Methods for Protein Aggregate Quantification: Application to BSA in Chromatographic Processes

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Protein aggregation poses a significant risk to biopharmaceutical product quality, as even minor amounts of oligomeric species can compromise efficacy and safety. Rapid and reliable detection of protein aggregates thus remains a major challenge in biopharmaceutical manufacturing.

A Rigorous Solution to the Superluminal Issue in the Diffusion Equation

The Astrophysical Journal
Superluminal propagation is an intrinsic problem in the diffusion equation and has not been effectively addressed for a long time. In this work, a rigorous solution to this issue is obtained under the assumption that particles undergo a random flight ...

Role of line-of-sight cosmic ray interactions in forming the spectra of distant blazars in TeV gamma rays and high-energy neutrinos

, 2011
Active galactic nuclei (AGN) can produce both gamma rays and cosmic rays. The observed high-energy gamma-ray signals from distant blazars may be dominated by secondary gamma rays produced along the line of sight by the interactions of cosmic-ray protons ...

Innovative methodology for flexible monitoring of various bioprocesses by using pre‐existing Raman data coupled with automated transfer learning technique

Biotechnology Progress, EarlyView.
The application of the transfer learning algorithm successfully allowed the use of a model built on process A for real‐time monitoring of process B. This study shows the improvement obtained with this methodology compared to the direct application of the model.

Emission of cosmic rays from Jupiter: magnetospheres as possible sources of cosmic rays

European Physical Journal C: Particles and Fields, 2018
Measurements made recently with the PAMELA satellite during a period of 8 years have shown with good evidence that a fraction of the cosmic rays detected on Earth comes from Jupiter.

Bioactive Magnesium Silicate Activating Myocardial Energy Metabolism For Infarcted Myocardium Repair

Exploration, EarlyView.
ABSTRACT The heart is a highly energy‐dependent organ, developing bioenergy‐activating biomaterials to activate myocardial adenosine triphosphate (ATP) production and restore dysregulated energy homeostasis is a promising solution for its functional recovery.

Testing Fundamental Physics with High-Energy Cosmic Rays [PDF]

, 2000
Cosmic rays may provide opportunities for probing fundamental physics. For example, ultra-high-energy cosmic rays might originate from the decays of metastable heavy particles, and astrophysical gamma rays can be used to test models of quantum gravity ...
