$^{6}_{\Lambda\Lambda}$He and $^{10}_{\Lambda\Lambda}$Be hypernuclei calculations with realistic interactions [PDF]

Brazilian Journal of Physics, 2003
We study the $^{6}_{\Lambda\Lambda}$He and $^{10}_{\Lambda\Lambda}$Be hypernuclei in the three- and four-body models, respectively, employing harmonic oscillator bases and presently most realistic alpha-alpha, alpha-lambda and lambda-lambda interactions. In order to improve convergence we use correlation functions in the case of $^{10}_{\Lambda\Lambda}$

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Reducing reliability bias in assessments of extreme weather risk using calibrating priors [PDF]

Advances in Statistical Climatology, Meteorology and Oceanography
A number of recent climate studies have used univariate parametric statistical models to estimate return periods of extreme weather events based on the method of maximum likelihood.

$\Lambda {\bar{\Lambda }}$ final-state interaction in the reactions $e^+e^- \rightarrow \phi {\Lambda }{\bar{{\Lambda }}}$ and $e^+e^- \rightarrow \eta {\Lambda }{\bar{{\Lambda }}}$

, 2023
Near-threshold ΛΛ¯ mass spectra for the reactions e+e−→ηΛΛ¯ and e+e−→ϕΛΛ¯ are investigated with an emphasis on the role played by the interaction in the ΛΛ¯ system. A variety of ΛΛ¯ potential models is employed that have been established in the analysis of data on pp¯→ΛΛ¯ in the past. It is shown that the near-threshold enhancement observed for the two

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Aster-B coordinates with Arf1 to regulate mitochondrial cholesterol transport

Molecular Metabolism, 2020
Objective: Cholesterol plays a pivotal role in mitochondrial steroidogenesis, membrane structure, and respiration. Mitochondrial membranes are intrinsically low in cholesterol content and therefore must be replenished with cholesterol from other ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

The integral part of a nonlinear form with a square, a cube and a biquadrate

Open Mathematics, 2020
In this paper, we show that if λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} are non-zero real numbers, and at least one of the numbers λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} is irrational, then the integer parts of λ1n12+λ2n23+λ3n34{
