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

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 ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

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.

Three-Dimensional Simulation Model for Synergistically Simulating Urban Horizontal Expansion and Vertical Growth

Remote Sensing, 2022
Urban expansion studies have focused on two-dimensional planar dimensions, ignoring the impact of building height growth changes in the vertical direction on the urban three-dimensional (3D) spatial expansion.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

3D simulation using the lattice Boltzmann method of heat transfer in a local with different door positions [PDF]

EPJ Web of Conferences
This study numerically examines three-dimensional natural convection in a bottom-heated, closed cubic cavity using the lattice Boltzmann method. The computational approach relies on a D3Q15 lattice scheme coupled with a single-time relaxation (SRT ...
