Interaction of Protons with Noble-Gas Atoms: Total and Differential Cross Sections

Atoms
We present a classical treatment of the ionization and electron-capture processes in the interaction of protons with neutral noble-gas atoms, namely, Ne, Ar, Kr, and Xe. We used a three-body classical-trajectory Monte Carlo (CTMC) method to calculate the

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Unveiling radii and neutron skins of unstable atomic nuclei via nuclear collisions

Frontiers in Physics
Total reaction, interaction, and charge-changing cross sections, which are kinds of cross sections standing for total nuclear collision probability in medium-to high-energy region from a few to several hundred MeV, have been extensively utilized to probe

Electron-Impact Ionization of Heavy Atoms Using the Time-Dependent Close-Coupling Method

Atoms, 2021
The time-dependent close-coupling method has been recently applied to calculate electron-impact direct ionization cross sections for the Kr, W, and Pb atoms. An overview is presented for these three heavy neutral atom systems.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Covariance analysis for total neutron cross sections based on a microscopic optical   model potential

EPJ Nuclear Sciences & Technologies, 2018
The deterministic simple least square (LS) approach is employed in the covariance analysis of the total neutron cross section (n,tot) calculated by a microscopic optical potential, CTOM, which is based on a fundamental theory − Dirac Brueckner Hartree ...

Simple Model for Total Cross Sections

, 1997
Adopting the philosophy à la Donnachie and Landshoff that simple pole exchanges could account for all data of total, elastic and diffractive scattering cross sections to present energies, we show that such simple pole fits to $pp$ and ${\bar p}p$ total cross sections are indeed very successful.

Neutron-nucleus total cross sections at 5.7 GeV/c [PDF]

, 1970
The neutron total cross sections for He, Be, C, Al, Fe, Cu, Cd, W, Pb and U have been measured to an accuracy of 2% at 5.7 +/- 0.6 GeV/c. The total cross section versus atomic weight data was fit to an absorbing uniform grey sphere optical model.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

On the Electron Impact Integral Cross-Sections for Butanol and Pentanol Isomers

Atoms, 2021
The need for a reliable and comprehensive database of cross-sections for many atomic and molecular species is immense due to its key role in R&D domains such as plasma modelling, bio-chemical processes, medicine and many other natural and technological ...
