Mechanical Spin Waves in a Nonlocal Discrete Magnetoelastic Lattice with Negative Group Velocity
Advanced Physics Research, EarlyView.A discrete magnetoelastic lattice enables mechanical spin waves. The zigzag‐arranged lattice consists of repulsive magnets. The top and bottom rows of the zigzag lattice show opposite spin directions. These spin waves arise due to the coupling between longitudinal and transverse motions.

Solvability of nonlinear elliptic equations with gradient terms
Journal of Differential Equations, 2013 We study the solvability in the whole Euclidean space of coercive quasi-linear and fully nonlinear elliptic equations modeled on $ u\pm g(|\nabla u|)= f(u)$, $u\ge0$, where $f$ and $g$ are increasing continuous functions. We give conditions on $f$ and $g$ which guarantee the availability or the absence of positive solutions of such equations in $\R^N$.

Advanced Physics Research, EarlyView.A novel Photonic Crystal Fiber sensor with an octagonal cladding and hollow core is developed to detect kerosene adulteration. At 2.2 THz, the sensor achieves 96.80% relative sensitivity, an effective mode loss of 0.00667 cm⁻¹, and minimal confinement loss (6.78 × 10⁻8 dB m−1).

Electronic Journal of Differential Equations, 2000 solutions to nonlinear equations and to (non)resonant semilinear equations involving nonlinear perturbations of Fredholm maps of index zero. We apply our results to semilinear elliptic, and to semilinear parabolic and hyperbolic periodic boundary-value ...

A degree theory for second order nonlinear elliptic operators with nonlinear oblique boundary conditions [PDF]
arXiv, 2015 In this paper we introduce an integer-valued degree for second order fully nonlinear elliptic operators with nonlinear oblique boundary conditions. We also give some applications to the existence of solutions of certain nonlinear elliptic equations arising from a Yamabe problem with boundary and reflector problems.

$C^{2,α}$ estimates for nonlinear elliptic equations of twisted type [PDF]
arXiv, 2015 We prove a priori interior $C^{2,\alpha}$ estimates for solutions of fully nonlinear elliptic equations of twisted type. For example, our estimates apply to equations of the type convex + concave. These results are particularly well suited to equations arising from elliptic regularization. As application, we obtain a new proof of an estimate of Streets-

Fast and scalable inference for spatial extreme value models
Canadian Journal of Statistics, EarlyView.Abstract The generalized extreme value (GEV) distribution is a popular model for analyzing and forecasting extreme weather data. To increase prediction accuracy, spatial information is often pooled via a latent Gaussian process (GP) on the GEV parameters. Inference for GEV‐GP models is typically carried out using Markov Chain Monte Carlo (MCMC) methods,
