Advanced Science, EarlyView.A stretchable OLED fiber display is developed by introducing a novel robust, conductive, and deformable via (RCD‐via) that maintains electrical and mechanical integrity under strain. Through scalable integration and mechanical design, the display operates reliably even during stretching, offering a promising strategy for truly wearable textile ...

Continuous spectrum of a fourth order nonhomogeneous elliptic equation with variable exponent
Electronic Journal of Differential Equations, 2011 In this article, we consider the nonlinear eigenvalue problem $$displaylines{ Delta(|Delta u|^{p(x)-2}Delta u )=lambda |u|^{q(x)-2}uquad hbox{in }Omega, cr u=Delta u = 0quad hbox{on }partialOmega, }$$ where $Omega$ is a bounded domain in $mathbb{R}^

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution
Advanced Science, EarlyView.The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...

Error investigation of finite element approximation for a nonlinear Sturm–Liouville problem
Учёные записки Казанского университета: Серия Физико-математические науки, 2017 A positive definite differential eigenvalue problem with coefficients depending nonlinearly on the spectral parameter has been studied. The differential eigenvalue problem is formulated as a variational eigenvalue problem in a Hilbert space with bilinear

Advanced Science, EarlyView.We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Nanoscopic Mapping of the Extracellular Space in Amyloid Plaque‐rich Cortex
Advanced Science, EarlyView.The extracellular space and diffusion around amyloid plaques are examined using shadow imaging and single‐particle tracking. Increased diffusivity is found near plaques, extracellular matrix alterations, and plaque core penetrability that varies with amyloid phenotype.

An eigenvalue problem possessing a continuous family of eigenvalues plus an isolated eigenvalue
Communications on Pure and Applied Analysis, 2010 In this paper we analyze an eigenvalue problem, involving a homogeneous Neumann boundary condition, in a smooth bounded domain. We show that the problem possesses, on the one hand, a continuous family of eigenvalues and, on the other hand, exactly one more eigenvalue which is isolated in the set of eigenvalues of the problem.
