Electrically Coded Retinomorphic Spectrophotodetector

Advanced Materials, EarlyView.
Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.

Boundary conditions of nonlocal type in weighted Sobolev spaces for nonlinear elliptic problems

Results in Applied Mathematics
This paper addresses proving that solutions exist for nonlinear elliptic problems characterized by boundary conditions of non-local type, as well as their uniqueness, within the framework of weighted Sobolev spaces.

Analysis of Non-Monotonic Piecewise Lyapunov Stability and Semi-PID Design for MIMO Piecewise Affine Systems [PDF]

International Journal of Research and Technology in Electrical Industry
In this study, we introduce the Non-monotonic Lyapunov (NML) approach, aimed at stability examining and designing stabilizable controller for a specific category of discrete piecewise affine dynamical systems.

Unveiling α‐MoO3 as a High‐Index, Low‐Loss Anisotropic Material: Bridging the Gap From Mid‐Infrared to Ultraviolet Nanophotonics

Advanced Materials, EarlyView.
α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

Development of a total variation diminishing (TVD) sea ice transport scheme and its application in an ocean (SCHISM v5.11) and sea ice (Icepack v1.3.4) coupled model on unstructured grids [PDF]

Geoscientific Model Development
As the demand for increased resolution and complexity in unstructured sea ice models is growing, higher demands are also placed on the sea ice transport scheme. In this study, we couple the Semi-implicit Cross-scale Hydro-science Integrated System Model (

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

Advanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

"Non-strict" l'Hospital-Type Rules for Monotonicity: Intervals of Constancy

, 2006
Assuming that a "derivative" ratio rho:=f'/g' of the ratio r:=f/g of differentiable functions f and g is strictly monotonic (that is, rho is increasing or decreasing), it was shown in previous papers that then r can switch at most once, from decrease to increase or vice versa.

Universal Strategy for Phase‐Selective Synthesis of Monolayer TMDs via Colloidal Chemistry

Advanced Materials, EarlyView.
ABSTRACT Colloidal synthesis of monolayer transition metal dichalcogenides (TMDs) remains challenging regarding uniform size, thickness, and crystalline phase. While significant progress has been made in phase engineering, a unified chemical strategy for on‐demand selection of both 2H and 1T′ phases across multiple TMD systems within a single chemical ...

Eigenvalue problems for the p-Laplacian with indefinite weights

Electronic Journal of Differential Equations, 2001
We consider the eigenvalue problem $-Delta_p u=lambda V(x) |u|^{p-2} u, uin W_0^{1,p} (Omega)$ where $p>1$, $Delta_p$ is the p-Laplacian operator, $lambda >0$, $Omega$ is a bounded domain in $mathbb{R}^N$ and $V$ is a given function in $L^s (Omega)$ ($s$
