Two-dimensional beams in rectangular coordinates using the radial point interpolation method

REM: International Engineering Journal, 2019
The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational

Kinetic and structural characterisation of domain‐specific angiotensin I‐converting enzyme inhibition by captopril, rentiapril and zofenoprilat

The FEBS Journal, EarlyView.
Angiotensin I‐converting enzyme (ACE) contains two catalytic domains (nACE and cACE) and is a key therapeutic target for hypertension and cardiovascular disease. Current ACE inhibitors (ACEi) nonselectively inhibit both domains, causing adverse effects. Selective inhibition requires an understanding of domain‐specific binding.

NURBS-Enhanced Meshfree Method with an Integration Subtraction Technique for Complex Topology

Applied Sciences, 2020
In this paper, we present an integration subtraction technique to model holes interactively in a predesigned domain for adaptive problems. This technique involves two approaches, the normal subtraction technique and the moving subtraction technique.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

The FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and
