Astrophysical Implication of Low E(2^+_1) in Neutron-rich Sn Isotopes

, 2009
The observation and prediction of unusually depressed first excited 2^+_1 states in even-A neutron - rich isotopes of semi-magic Sn above 132Sn provide motivations for reviewing the problems related to the nuclear astrophysics in general.

Temporal decay bounds in generalized heat conduction

Journal of Mathematical Analysis and Applications, 2004
The authors consider the generalized Maxwell-Cattaneo model for heat conduction in \(\mathbb R^N\) \((N = 2, 3)\). By using a suitable change of variable for the temperature \(T\) and exploiting the multiplier method, they establish an exponential decay bounds for \(T\), as well as its first partial derivatives, in the \(L_2(\Omega)\) norm.

Multiscale Modeling of Process‐Induced Defects in Fused Filament Fabrication‐Printed Materials

Advanced Engineering Materials, EarlyView.
This study presents a predictive multiscale modeling tool for defect analysis of fused filament fabricated‐printed materials and their performance prediction using a mechanistic data science‐based reduced‐order modeling approach. Process‐induced defects are inherent to additively manufactured parts and significantly influence the performance of printed

An Analysis of the Decay $B \rightarrow D^* X \ell \bar\nu_\ell$ with Predictions from Heavy Quark and Chiral Symmetry

, 1992
This paper considers the implications of the heavy quark and chiral symmetries for the semi-leptonic decay $B \rightarrow D^* X \ell \bar \nu_\ell$. The general kinematic analysis for decays of the form {\sl pseudoscalar meson $\rightarrow$ vector meson $

General decay for a viscoelastic rotating Euler-Bernoulli beam

Communications on Pure and Applied Analysis, 2020
In this paper, we consider a viscoelastic rotating Euler-Bernoulli beam that has one end fixed to a rotated motor in a horizontal plane and to a tip mass at the other end. For a large class relaxation function \begin{document}$ q $\end{document} , namely,

Decay of Fourier Transforms and Generalized Besov Spaces

Constructive Mathematical Analysis, 2020
A characterization of the generalized Lipschitz and Besov spaces in terms of decay of Fourier transforms is given.\ In particular, necessary and sufficient conditions of Titchmarsh type are obtained.\ The method is based on two-sided estimate for the rate of approximation of a $\beta$-admissible family of multipliers operators in terms of decay ...

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves

Advanced Engineering Materials, EarlyView.
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.
