Ultrafast electro-nuclear dynamics of H2 double ionization [PDF]
, 2007 The ultrafast electronic and nuclear dynamics of H2 laser-induced double ionization is studied using a time-dependent wave packet approach that goes beyond the fixed nuclei approximation.

Double ionization of a three-electron atom: Spin correlation effects
, 2019 We study the effects of spin degrees of freedom and wave function symmetries on double ionization in three-electron systems. Each electron is assigned one spatial degree of freedom.

Effect of impact ionization in the InGaAs absorber on excess noise of avalanche photodiodes [PDF]
, 2005 The effects of impact ionization in the InGaAs absorption layer on the multiplication, excess noise and breakdown voltage are modeled for avalanche photodiodes (APDs), both with InP and with InAlAs multiplication regions.

Low ionization state plasma in CMEs
, 2012 The Ultraviolet Coronagraph Spectrometer on board the Solar and Heliospheric Observatory (SOHO) often observes low ionization state coronal mass ejection (CME) plasma at ultraviolet wavelengths. The CME plasmas are often detected in O VI (3x10^5K), C III

One-photon double ionization of helium: a heuristic formula for the cross section
, 2011 Without a formal derivation, we propose a formula for the total and single-differential cross in the problem of one-photon double ionization of an atom.

EMS Newsletter, 2020 Summary: ``How many electrons can a nucleus bind?'' is as old as quantum mechanics, but its rigorous answer based on the many-body Schrödinger equation remains a difficult challenge to mathematicians. Nevertheless, there has been remarkable progress in this problem in the past four decades.

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 ...

Few Body Effects in the Electron and Positron Impact Ionization of Atoms
Atoms, 2021 Triple differential cross sections (TDCS) are presented for the electron and positron impact ionization of inert gas atoms in a range of energy sharing geometries where a number of significant few body effects compete to define the shape of the TDCS ...

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression
Molecular Oncology, EarlyView.Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.
