Computational Thermodynamic Design of Nb–Mo‐Based Refractory Multi‐Principal Element Alloy for Hydrogen Energy Storage

MetalMat, EarlyView.
Through the use of thermophysical parameter analysis, CALPHAD‐based thermodynamic modeling, and open‐source pressure–composition–temperature (PCT) simulations, Al3Nb60Mo20V16Cr1 was discovered to be a BCC refractory multi‐principal element alloy (RMPEA) with ideal stability for solid‐state hydrogen storage.

Dry intrusions and warm‐core development in Medicanes: Insights from a multi‐case analysis and the peculiar evolution of Ianos

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Mediterranean tropical‐like cyclones show a clear seasonality, with September cyclones exhibiting the deepest convection and Ianos representing the most extreme case. While one or more dry intrusions are typically detected during the cyclone life cycle, Ianos instead features two much weaker descending airflows.

THD performance of single phase five level inverter using proportional resonant and harmonic compensators current controller [PDF]

, 2020
This paper observe the total harmonic distortion (THD) performance of single phase five level inverter using proportional resonant (PR) and harmonic compensators current controller. The THD when adding PR current controller was 1.6% at first.

The HubBLe Trial: haemorrhoidal artery ligation (HAL) versus rubber band ligation (RBL) for symptomatic second- and third-degree haemorrhoids: a multicentre randomised controlled trial and health-economic evaluation

Health Technology Assessment, 2016
Background: Optimal surgical intervention for low-grade haemorrhoids is unknown. Rubber band ligation (RBL) is probably the most common intervention. Haemorrhoidal artery ligation (HAL) is a novel alternative that may be more efficacious.

Improvement in Hemorrhoidal Disease Surgery Outcomes Using a New Anatomical/Clinical–Therapeutic Classification (A/CTC)

The Surgery Journal, 2020
Introduction The introduction and diffusion of new techniques for hemorrhoidal surgery have made it clear how much Goligher classification is inadequate in the modern times, lacking in any correlation between anatomical and clinical features to a ...

Unraveling the effect of topological structures of B/N‐doped conjugated macrocycles on spectral properties: A computational study

Smart Molecules, EarlyView.
Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.
