Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

Advanced Engineering Materials, EarlyView.
High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

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.

Novel Surface‐Based Bézier Metamaterials: A Higher Degree of Parametrization toward Tailoring the Effective Properties under Compression

Advanced Engineering Materials, EarlyView.
Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

Aging Phenotypes of Common Marmosets (Callithrix jacchus)

Journal 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.

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{

Direct Electron Detection Electron Energy‐Loss Spectroscopy: Speeding Up 2D Analytical In Situ Transmission Electron Microscopy for Aluminum Alloys

Advanced Engineering Materials, EarlyView.
Scanning transmission electron microscopy imaging techniques are an essential tool to document dynamic developments, such as precipitation in aluminum alloys, during in situ heating experiments using transmission electron microscopy. However, in many cases, chemical information is required to interpret complex nanoscale processes.

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

Advanced Engineering Materials, EarlyView.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.

$$\Lambda _b$$ 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

European 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 ...

The segregated $\Lambda$-coalescent [PDF]

The Annals of Probability, 2015
We construct an extension of the Lambda-coalescent to a spatial continuum and analyse its behaviour. Like the Lambda-coalescent, the individuals in our model can be separated into (i) a dust component and (ii) large blocks of coalesced individuals. We identify a five phase system, where our phases are defined according to changes in the qualitative ...
