General decay for a nonlinear pseudo-parabolic equation with viscoelastic term
Demonstratio Mathematica, 2022 This work is concerned with a multi-dimensional viscoelastic pseudo-parabolic equation with critical Sobolev exponent. First, with some suitable conditions, we prove that the weak solution exists globally.

Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Vacuum Decay in General Relativity
, 2018 We provide a novel, concise and self-contained evaluation of true- and false vacuum decay rates in general relativity. We insist on general covariance and choose observable boundary conditions, which yields the well known false-vacuum decay rate and a new true-vacuum decay rate that differs significantly from prior work.

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

AxiomsWe investigate an inverse problem involving source and damping term with variable-exponent nonlinearities. We establish adequate conditions on the initial data for the decay of solutions as the integral overdetermination approaches zero over time within ...

, 2008 We present a model for nonlinear decay of the weak wave in three-dimensional incompressible magnetohydrodynamic (MHD) turbulence. We show that the decay rate is different for parallel and perpendicular waves.

Generation Structure and Proton Decay Problem [PDF]
Progress of Theoretical Physics, 2001 Possible generation structure is investigated. We considere alternative possibility of combination of leptons and quarks to compose each generation, where the combination of $( _ , )$ and $(u,d)$ compose a generation. Our model exhibits the hierarcy structure after sea-saw mechanism provived that possible existence of realistic right-handed ...

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Space–time evolution of heavy sterile neutrinos in cascade decays
Nuclear Physics B, 2014 Heavy sterile-like neutrinos may be produced resonantly from the decay of pseudoscalar mesons and may decay into several different channels in a cascade Φ→Lανh; νh→{X}. In general these are rare events with displaced vertices.

Is Generalization Decay a Fundamental Law of Psychology?
Behavioral and Brain Sciences, 2023 Generalizations strengthen in traditional sciences, but in psychology (and social and behavioral sciences, more generally) they decay. This is usually viewed as problem requiring solution, but it could be viewed as a law-like phenomenon. Generalization decay cannot be squelched because human behavior is metastable and all behavioral data collected thus
