Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Direct numerical simulation of inclusion floating and collision behavior in molten steel using the lattice Boltzmann method

open access: yes工程科学学报, 2016
The floating and collision behavior of inclusions in the floating process was numerically simulated by using the Lattice Boltzmann method. It is found that the floating velocity simulation results of different size inclusion particles are almost the same

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS 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 ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Mesoscopic Parameter Calibration Method of Accumulated Debris Materials Based on Direct Shear Test and Simulation Verification

open access: yes工程科学与技术, 2022
The reliability of three-dimensional discrete element numerical simulation of granular materials depends on the reasonable calibration of mesoscopic parameters. At present, systematic research on the calibration method of mesoscopic parameters is lacking.

Direct numerical simulation for investigation on yaw angle effects on riblets

open access: yesJournal of Fluid Science and Technology, 2017
The yaw angle (φ) effect on riblets are investigated by parametrically conducted direct numerical simulation (DNS). Three configurations are adopted: standard straight riblet, sinusoidal riblet, and modified sinusoidal riblet. The height of the side wall

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Direct numerical simulations of forced and unforced separation bubbles on an airfoil at incidence [PDF]

open access: yes, 2008
Direct numerical simulations (DNS) of laminar separation bubbles on a NACA-0012 airfoil at Re-c = 5 x 10(4) and incidence 5 degrees are presented. Initially volume forcing is introduced in order to promote transition to turbulence.

Direct numerical simulation of rising Taylor bubbles and interfacial species transfer [PDF]

open access: yesInternational Journal of Fluid Engineering
A direct numerical simulation (DNS) study is performed to investigate the flow field and interfacial species transfer around freely rising Taylor bubbles in a cylindrical pipe. The Eötvös number Eo is varied from 4.9 to 8.7, the bubble Reynolds number Re

Numerical simulation and evaluation of spacer-filled direct contact membrane distillation module

open access: yesApplied Water Science, 2020
Membrane fouling and temperature polarization are the most common issues that cause limitations to membrane distillation (MD) process. Integration of spacers has been proven to resolve those problems by inducing regions of turbulence and giving the ...
