Nonexistence of small, odd breathers for a class of nonlinear wave equations

, 2016
In this note, we show that for a large class of nonlinear wave equations with odd nonlinearities, any globally defined odd solution which is small in the energy space decays to $0$ in the local energy norm.

Nonexistence results for some nonlinear elliptic and parabolic inequalities with functional parameters

Electronic Journal of Qualitative Theory of Differential Equations, 2015
We obtain results on nonexistence of nontrivial nonnegative solutions for some elliptic and parabolic inequalities with functional parameters involving the $p(x)$-Laplacian operator. The proof is based on the test function method.

On the nonexistence of hypercommuting polynomials [PDF]

Proceedings of the American Mathematical Society, 1977
If f ( x 1 , … , x n ) f({x_1}, \ldots ,{x_n}) is not central for R, then the additive group generated by all specializations of f in R contains a noncentral Lie ideal of R.

Blow-up of solutions to fractional differential inequalities involving ψ-Caputo fractional derivatives of different orders

AIMS Mathematics, 2022
We consider a fractional differential inequality involving $ \psi $-Caputo fractional derivatives of different orders, with a polynomial nonlinearity and a singular potential term.

Remarks on two fourth order elliptic problems in whole space

, 2014
We are interested in entire solutions for the semilinear biharmonic equation $\Delta^{2}u=f(u)$ in $\R^N$, where $f(u)=e^{u}$ or $-u^{-p}\ (p>0)$. For the exponential case, we prove that any classical entire solution verifies $-\Delta u>0$ without any ...

Hip morphology‐based osteoarthritis risk prediction models: development and external validation using individual participant data from the World COACH Consortium

Arthritis Care &Research, Accepted Article.
Objectives This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the World COACH consortium ...

Thiosulfonate‐Derived BODIPY “Stick and Glue” Strategy for Fluorescent Thiol Labeling

Angewandte Chemie, EarlyView.
We present a powerful photochemical strategy for converting disulfide bonds into stable thioether linkages via a [1,2]‐sigmatropic rearrangement. By integrating this reaction into traditional methanethiosulfonate‐based thiol labeling, we enable light‐triggered stabilization of peptide and protein conjugates with enhanced robustness and versatility ...

High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

Advanced Engineering Materials, EarlyView.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...
