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

open access: yesAdvances 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.

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

open access: yesOpen 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{

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

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

open access: yesAdvanced 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.

Aging Phenotypes of Common Marmosets (Callithrix jacchus)

open access: yesJournal of Aging Research, 2012
Characterizing the phenotypic changes associated with aging in a short-lived primate is necessary in order to develop better translational models for human health, aging, and disease research.

$\Lambda$, $\bar{\Lambda}$ Polarization and Spin Transfer in Lepton Deep-Inelastic Scattering

open access: yes, 2000
The flavor and helicity distributions of the $\Lambda$ and $\bar{\Lambda}$ hyperons for both valence and sea quarks are calculated in a perturbative QCD (pQCD) based model.

Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

$$\Lambda _b$$ Λb decays into $$\Lambda _c^*\ell \bar{\nu }_\ell $$ Λc∗ℓν¯ℓ and $$\Lambda _c^*\pi ^-$$ Λc∗π- $$[\Lambda _c^*=\Lambda _c(2595)$$ [Λc∗=Λc(2595) and $$\Lambda _c(2625)]$$ Λc(2625)] and heavy quark spin symmetry

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We study the implications for $$\Lambda _b \rightarrow \Lambda _c^*\ell \bar{\nu }_\ell $$ Λb→Λc∗ℓν¯ℓ and $$\Lambda _b \rightarrow \Lambda _c^*\pi ^-$$ Λb→Λc∗π- $$[\Lambda _c^*=\Lambda _c(2595)$$ [Λc∗=Λc(2595) and $$\Lambda _c(2625)]$$ Λc(2625)] decays ...

Tensor coupling effects on spin symmetry in anti-Lambda spectrum of hypernuclei

open access: yes, 2010
The effects of $\bar\Lambda\bar\Lambda\omega$-tensor coupling on the spin symmetry of $\bar{\Lambda}$ spectra in $\bar{\Lambda}$-nucleus systems have been studied with the relativistic mean-field theory.

Interferon-lambda: a new addition to an old family.

open access: yesJournal of Interferon and Cytokine Research, 2010
The discovery and initial description of the interferon-lambda (IFN-lambda) family in early 2003 opened an exciting new chapter in the field of IFN research.
