A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Dynamics of quantum information resources in two-flavor neutrino oscillations

European Physical Journal C: Particles and Fields
The burgeoning intersection of particle physics and quantum information science unveils significant connections, particularly in the context of neutrinos–fundamental particles that challenge our understanding of mass, mixing, and coherence at the quantum

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

A multistate platform model for time‐to‐event endpoints in oncology clinical trials

CPT: Pharmacometrics & Systems Pharmacology
A multistate platform model was developed to describe time‐to‐event (TTE) endpoints in an oncology trial through the following states: initial, tumor response (TR), progressive disease (PD), overall survival (OS) event (death), censor to the last ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Integration of Time‐Varying Pharmacometric Modeling With Cox Regression for Time‐to‐Event Analysis in NONMEM

CPT: Pharmacometrics & Systems Pharmacology
Although time‐varying Cox regression modeling approaches have been developed, exposure–response analyses for time‐to‐event (TTE) endpoints often rely on static exposure covariates and may overlook the real‐world dosing variability and drug concentration ...

Applying the Levels of Conceptual Interoperability Model in Support of Integratability, Interoperability, and Composability for System-of-Systems Engineering [PDF]

Journal of Systemics, Cybernetics and Informatics, 2007
The Levels of Conceptual Interoperability Model (LCIM) was developed to cope with the different layers of interoperation of modeling and simulation applications.

Mathematical modeling of Echinococcosis in humans, dogs and livestock with optimal control strategies [PDF]

Iranian Journal of Numerical Analysis and Optimization
In this paper, we present a deterministic model of Cystic Echinococcosis disease of eleven differential equations, describing complex interactions between three types of hosts, specifically humans, livestock and dogs.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
