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

open access: yesEPJ 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 ...

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

open access: yesFEBS 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 ...

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

open access: yesAtoms, 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 ...

Q-ball collisions in the MSSM: gauge-mediated supersymmetry breaking [PDF]

open access: yes, 2000
Collisions of non-topological solitons, Q-balls, are considered in the Minimal Supersymmetric Standard Model where supersymmetry has been broken at a low energy scale via a gauge mediated mechanism.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Total cross sections of eγ → eX X ¯ $$ eX\overline{X} $$ processes with X = μ, γ, e via multiloop methods

open access: yesJournal of High Energy Physics, 2021
Using modern multiloop calculation methods, we derive the analytical expressions for the total cross sections of the processes e − γ → e − X X ¯ $$ {e}^{-}X\overline{X} $$ with X = μ, γ or e at arbitrary energies.

Simple function forms and nucleon-nucleus total cross sections

open access: yes, 2004
Total cross sections for neutron scattering with energies between 10 and 600 MeV and from nine nuclei spanning the mass range from 6Li to 238U have been analyzed using a simple function of three parameters.

Total neutrino and antineutrino nuclear cross sections around 1 GeV [PDF]

open access: yes, 2006
We investigate neutrino-nucleus interactions at energies around 1 GeV. In this regime, the main contributions to the cross sections come from quasi-elastic and $\Delta$ production processes.

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

open access: yesFEBS 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.
