Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

The relaxation effect of prolonged expiratory breathing
Mental Illness, 2018 This study was performed to confirm that autonomic nervous activity is affected by breathing speed. I hypothesized that prolonged expiratory breathing would promote parasympathetic dominance, whereas rapid breathing would promote sympathetic dominance ...

Subordination model of anomalous diffusion leading to the two-power-law relaxation responses
, 2010 We derive a general pattern of the nonexponential, two-power-law relaxation from the compound subordination theory of random processes applied to anomalous diffusion.

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation
Advanced Engineering Materials, EarlyView.This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Stretched exponential relaxation in the Coulomb glass
, 2001 The relaxation of the specific heat and the entropy to their equilibrium values is investigated numerically for the three-dimensional Coulomb glass at very low temperatures. The long time relaxation follows a stretched exponential function, $f(t)=f_0\exp[

Advanced Engineering Materials, EarlyView.Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Decay results for viscoelastic diffusion equations in absence of instantaneous elasticity
Electronic Journal of Differential Equations, 2012 We study the diffusion equation in the absence of instantaneous elasticity $$ u_t-int_0^{t}g(t-au )Delta u(au ),dau =0,quad (x,t)in Omega imes (0,+infty ), $$ where $Omega subset mathbb{R}^n$, subjected to nonlinear boundary conditions.
