Adaptive transition rates in excitable membranes [PDF]
Frontiers in Computational Neuroscience, 2009 Adaptation of activity in excitable membranes occurs over a wide range of timescales. Standard computational approaches handle this wide temporal range in terms of multiple states and related reaction rates emanating from the complexity of ionic channels.

A technique for approximating transition rates from published survival analyses [PDF]
Cost Effectiveness and Resource Allocation, 2019 Background Quality-adjusted-life-years (QALYs) are used to concurrently quantify morbidity and mortality within a single parameter. For this reason, QALYs can facilitate the discussion of risks and benefits during patient counseling regarding treatment ...

Superstructure and Distorted-Wave Codes and Their Applications
Atoms, 2022 There have been many observations of the solar and astrophysical spectra of various ions. The diagnostics of these observations require atomic data that include energy levels, oscillator strengths, transition rates, and collision strengths.

Relativistic Configuration-Interaction and Perturbation Theory Calculations for Heavy Atoms
Atoms, 2021 Heavy atoms present challenges to atomic theory calculations due to the large number of electrons and their complicated interactions. Conventional approaches such as calculations based on Cowan’s code are limited and require a large number of parameters ...

Atomic Lifetimes of Astrophysical Interest in Ions of Fe
Atoms, 2023 Multiply charged ions of iron dominate the EUV spectrum of the solar corona. For the interpretation of such spectra, data on both the atomic structure and the transition rate are essential, most of which are provided by theory and computation.
