A Rapid Method for Measuring the Volume of a Large Cavity Using Averaged Absorption Cross Section

open access: yesIEEE Access, 2017
The rapid and accurate measurement of the volume of a large cavity is much in demand in practice, especially for a cavity of irregular shape. In this paper, a new method is proposed to measure the volume of a large cavity.

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

open access: yesFEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

P6.04 PULSE VOLUME HOMEOSTASIS AS A HYPOTHESIZED PRINCIPLE OF ARTERIAL DESIGN

open access: yesArtery Research, 2013
The increase of arterial volume during the systole (‘pulse volume’) is essential for buffering the pulsatile ventricular output. Objectives: Deriving some mechanical properties of arteries by assuming pulse volume homeostasis.

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‐

Stable degeneration of families of klt singularities with constant local volume

open access: yesForum of Mathematics, Sigma
For a klt singularity, C. Xu and Z. Zhuang [33] proved the associated graded algebra of a minimizing valuation of the normalized volume function is finitely generated, finishing the proof of the stable degeneration conjecture proposed by C. Li and C. Xu.

Simulation studies of combustion in a constant-mass variable-volume combustion chamber [PDF]

open access: yesFME Transactions, 2018
A numerical simulation code was used to conduct a systematic study of the effects of fuel-air equivalence ratios in the range 0.7 ≤ φ ≤ 1.4 and compression ratio, rc = 8.0 on key operating parameters, such as pressure, rate of change of pressure, '/dt ...

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

open access: yesFEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

A microfluidic study on the influence of naturally fractured porous media on the phase behavior of condensate gas depletion

open access: yesNatural Gas Industry B
There are limited quantitative studies on condensate gas using microfluidics under high-pressure and high-temperature conditions. This study employed microfluidics chips based on real porous media structures to conduct constant volume depletion ...

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 ...

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.
