Non-homogeneous problem for fractional Laplacian involving critical Sobolev exponent
In this article, we study the existence of positive solutions for the nonhomogeneous fractional equation involving critical Sobolev exponent $$\displaylines{ (-\Delta)^{s} u +\lambda u=u^p+\mu f(x), \quad u>0\quad \text{in } \Omega,\cr u =0, \quad \

Phase transitions of wave packet dynamics in disordered non-Hermitian systems
Disorder can localize the eigenstates of one-dimensional non-Hermitian systems, leading to an Anderson transition with a critical exponent of 1. We show that, due to the lack of energy conservation, the dynamics of individual, real-space wave packets ...

A series of ultraviolet‐ and near‐infrared radiation sensitive photoactivatable hydrogels are developed that can be controlled spatiotemporally down to µm precisions using one‐ and two‐photon uncaging. The latent hydroxylamine‐, hydrazine‐, and amine uncaged moieties are used to photopattern a series of diverse proteins displaying complimentary ...

The existence of ground state solutions for critical Hénon equations in $\mathbb{R}^N$ [PDF]
In this paper we confirm that $2^*(\gamma)=\frac{2(N+\gamma)}{N-2}$ with $\gamma>0$ is exactly the critical exponent for the embedding from $H_r^1(\mathbb{R}^N)$ into $L^q(\mathbb{R}^N;|x|^\gamma)$($N\geqslant 3$) (see \cite{2007SWW-1,2007SWW-2}) and name it as the upper H\'enon-Sobolev critical exponent.

Optical Hydrogen Sensing Materials for Applications at Sub‐Zero Temperatures
This study demonstrates the viability of optical hydrogen sensors at temperatures as low as −60°C. Using advanced metal hydride materials, the sensors detect hydrogen with high sensitivity, speed, and stability across a wide range of concentrations. These findings open doors for safe hydrogen detection in extreme cold, enabling applications in aviation,

A Brezis-Nirenberg problem on hyperbolic spaces
We consider a Brezis-Nirenberg problem on the hyperbolic space $\mathbb{H}^n$. By using the stereographic projection, the problem becomes a singular problem on the boundary of the open ball $B_1(0)\subset \mathbb{R}^n$. Thanks to the Hardy inequality,

This work investigates modifying interfacial contacts in realizing giant‐performance semiconductor nanomembrane optoelectronics. Strategies, including surface reaction and buffer layer work‐function modulation, are explored to boost the Schottky barrier. An emerging material of YbOx is utilized for near‐ideal Ohmic contact.
