BRANCHING PROCESS MODELLING: A TOOL FOR DECIPHERING COMPLEX REAL-WORLD PHENOMENA USING R PROGRAMMING

FUDMA JOURNAL OF SCIENCES, 2023
The reproduction of organisms such as human beings, cells or neutrons can be modeled via branching processes.The theory of branching processes offers suitable mathematical models to depict the chance-based progression of systems, where elements like cells, particles, or general individuals replicate and perish over a certain lifespan.

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 ...

Matching of an observed event and its virtual model in relation to smart theories, coupled models and supervision of complex procedures—A review

Comptes Rendus. Physique
This contribution aims to illustrate the nature of the observation–modeling (or real–virtual) link, the importance of the exact model (or coupled model) in the matching involved in this link and the use of this link in the supervision of complex ...

Pedestrian simulation: Theoretical models vs. data driven techniques

International Journal of Transportation Science and Technology, 2018
This paper presents a comparison and relative assessment of data driven techniques and conventional theoretical pedestrian simulation models. Data driven methods are applied for simulating phenomena without a priori knowledge of parameter connections ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Modeling and Simulation in Engineering Design and Technology: Improving Project/Product Performance

International Journal of Technology, 2014
The use of modeling and simulation (M&S) to increase project or product performance within engineering design and technology is well recognized. The reasons for increasing the use of modeling and simulation applications include the ability to simulate ...

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...
