Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures
Advanced Engineering Materials, EarlyView.We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Multiple solutions to elliptic equations on $\mathbb{R}^N$ with combined nonlinearities
Electronic Journal of Qualitative Theory of Differential Equations, 2015 Summary: In this paper, we are concerned with the multiplicity of nontrivial radial solutions for the following elliptic equation \[ \begin{cases} - \Delta u +V(x)u = -\lambda Q(x)| u| ^{q-2}u+ Q(x)f(u),\quad x\in\mathbb{R}^N,\cr u(x)\rightarrow 0,\quad \hbox{as}\;| x| \rightarrow +\infty,\end{cases} \tag{*}{P\(_\lambda\)} \] where ...

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Mass minimizers and concentration for nonlinear Choquard equations in ${\mathbb R}^N$ [PDF]
Topological Methods in Nonlinear Analysis, 2016 In this paper, we study the existence of minimizers to the following functional related to the nonlinear Choquard equation: $$ E(u)=\frac{1}{2}\int_{\mathbb R^N}|\nabla u|^2+\frac{1}{2}\ds\int_{\mathbb R^N}V(x)|u|^2-\frac{1}{2p}\ds\int_{\mathbb R^N}(I_\alpha*|u|^p)|u|^p $$% on $\widetilde{S}(c)=\{u\in H^1(\mathbb R^N)\mid \int_{\mathbb R^N}V(x)|u|^2 0\

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Solving Systems of Non-Linear Equations by Broyden's Method with Projected Updates [PDF]
We introduce a modification of Broyden's method for finding a zero of n nonlinear equations in n unknowns when analytic derivatives are not available.

Existence results for nonlinear elliptic equations in bounded domains of $R^n$
Electronic Journal of Differential Equations, 2006 We establish existence results for the boundary-value problem $Delta u+f(.,u)=0$ in a smooth bounded domain in $mathbb{R}^n$ $(ngeq 2)$, where $f$ satisfies some appropriate conditions related to a Kato class.
