Consolidate Overview of Ribonucleic Acid Molecular Dynamics: From Molecular Movements to Material Innovations

open access: yesAdvanced Engineering Materials, EarlyView.
Molecular dynamics simulations are advancing the study of ribonucleic acid (RNA) and RNA‐conjugated molecules. These developments include improvements in force fields, long‐timescale dynamics, and coarse‐grained models, addressing limitations and refining methods.

Random Polygons and Estimations of π

open access: yesOpen Mathematics, 2019
In this paper, we study the approximation of π through the semiperimeter or area of a random n-sided polygon inscribed in a unit circle in ℝ2. We show that, with probability 1, the approximation error goes to 0 as n → ∞, and is roughly sextupled when ...

Global extrapolation procedures for special and general initial value problems [PDF]

open access: yes, 1986
Two- and three- grid global extrapolation procedures are considered fohe special and general initial value problems of arbitrary order r tq. Extrapolation formulas are developed for consistent numerical methods of arbitrary order p .

Synergistic Effects of Cerium and Magnesium on Optimizing Electrical Conductivity and Mechanical Properties of AlSi3 Cast Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the impact of Ce and/or Mg on the electrical conductivity (EC) and mechanical properties of AlSi3 cast alloy. It highlights the synergistic effects of Ce and Mg on eutectic Si modification and Mg solute reduction in the Al matrix, resulting in the optimization of EC, strength, and ductility of the alloy.

Low-frequency extrapolation with deep learning

open access: yesSEG technical program expanded abstracts, 2018
The lack of the low frequency information and good initial model can seriously affect the success of full waveform inversion (FWI) due to the inherent cycle skipping problem.

Aspects of SU(3) baryon extrapolation

open access: yes, 2009
We report on a recent chiral extrapolation, based on an SU(3) framework, of octet baryon masses calculated in 2+1-flavour lattice QCD. Here we further clarify the form of the extrapolation, the estimation of the infinite-volume limit, the extracted low ...

Geometry‐Based Scan Curve Analysis: Rapid Method for the Evaluation of Scan Strategies in Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,
