Building bridges between nuclear reactions and statistical models [PDF]

EPJ Web of Conferences
In modern nuclear data evaluations, nuclear reactions and statistical methods cannot be separated. Whereas the first one is continuously improved for many decades, the second one is now benefiting from large computer power.

Serological Detection of SARS-CoV-2 Antibodies in Naturally-Infected Mink and Other Experimentally-Infected Animals

Viruses, 2021
The recent emergence of SARS-CoV-2 in humans from a yet unidentified animal reservoir and the capacity of the virus to naturally infect pets, farmed animals and potentially wild animals has highlighted the need for serological surveillance tools. In this

Information entropy as a measure of the quality of a nuclear density distribution [PDF]

, 1997
The information entropy of a nuclear density distribution is calculated for a number of nuclei. Various phenomenological models for the density distribution using different geometry are employed.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Model of 9Be nucleus as "quasi-molecular" state of “n+a+a” system

Physical Sciences and Technology, 2015
The 9Be nuclide has been considered as a system of two alpha-particles and one neutron and it has been shown that such system can exist in "quasi-molecular" state, when the wave number of a pair of heavy particles becomes imaginary with the wave number

Hydrodynamical Simulations of Nuclear Rings in Barred Galaxies

, 2015
Dust lanes, nuclear rings, and nuclear spirals are typical gas structures in the inner region of barred galaxies. Their shapes and properties are linked to the physical parameters of the host galaxy.

Modern nuclear force predictions for the neutron-deuteron scattering lengths [PDF]

, 2003
The nd doublet and quartet scattering lengths have been calculated based on the modern NN and 3N interactions. We also studied the effect of the electromagnetic interactions in the form introduced in AV18. Switching them off for the various nuclear force

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Status of the Geant4 models for nuclear de-excitation [PDF]

EPJ Web of Conferences
The Geant4 hadronic physics sub-library includes an extended set of models for highand low-energy hadronic interactions. We report on recent developments in the Geant4 nuclear de-excitation module, which is used by many Geant4 models to simulate the de ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
