Assessment of Intramural Segment Compression in Anomalous Coronary Arteries through Patient-Specific Finite Element Modeling

Applied Sciences, 2023
Background: Anomalous Aortic Origin of a Coronary Artery (AAOCA) is a congenital condition that can lead to ischemia and sudden cardiac death. Current diagnostic tools are unable to fully quantify the pathological behavior that occurs mainly with ...

Capsular Repair Matters for Residual Micromotion After Latarjet. An Externally Controlled Trial from the La Tour Group

The Hive
Background: Even though surgery is commonly used to treat glenohumeral instability, there is no evidence that such treatment effectively corrects glenohumeral translation.

A phenology-based vegetation index classification (PVC) algorithm for coastal salt marshes using Landsat 8 images

International Journal of Applied Earth Observations and Geoinformation, 2022
Coastal salt marshes, as a globally significant intertidal ecosystem, are highly productive but extremely fragile and unstable. Mapping coastal salt marshes accurately is the basis of assessing global climate change, biological invasion, and coastal ...

Investigation the effective factors on the forces acting on the scoop in a gas centrifuge machine in three-dimensional conditions with the DSMC method [PDF]

مجله علوم و فنون هسته‌ای
This article presents a simulation of a scoop inside the rotor of a gas centrifuge machine in three dimensions. The scoop inside the centrifuge machine is 3D and curved in shape. Therefore, a 3D simulation is necessary to analyze the proper flow behavior

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Natural convective heat transfer characteristics of Al2O3-water nanofluids in a vertical cylindrical enclosure

Nihon Kikai Gakkai ronbunshu, 2020
The present numerical investigation deals with the natural convection in a vertical cylindrical enclosure with a water-based Al2O3 nanofluids. The enclosure with an aspect ratio of 1 (= diameter / height) is filled with Al2O3-water nanofluids or pure ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Numerical simulation of upper garment pieces-body under different ease allowances based on the finite element contact model

AUTEX Research Journal
The interval distribution under different ease allowances directly influences the dressing effect. However, the indistinct 3D dressing process and unclear interval distribution pose severe challenges to practical applications.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
