Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Multiplicity of symmetric solutions for a nonlinear eigenvalue problem in $R^n$
In this paper, we study the nonlinear eigenvalue field equation $$ -Delta u+V(|x|)u+varepsilon(-Delta_p u+W'(u))=mu u $$ where $u$ is a function from $mathbb{R}^n$ to $mathbb{R}^{n+1}$ with $ngeq 3$, $varepsilon$ is a positive parameter and $p$ greater

Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Inverse spectral problems for nonlinear Sturm-Liouville problems
This paper concerns the nonlinear Sturm-Liouville problem $$ -u''(t) + f(u(t)) = lambda u(t), quad u(t) > 0, quad t in I := (0, 1), quad u(0) = u(1) = 0, $$ where $lambda $ is a positive parameter. We try to determine the nonlinear term $f(u)$ by means

The analysis of nonlinear wave equations has experienced a dramatic growth in the last ten years or so. The key factor in this has been the transition from linear analysis, first to the study of bilinear and multilinear wave interactions, useful in the ...

Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices
This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...

On some nonlinear potential problems
The degree theory of mappings is applied to a two-dimensional semilinear elliptic problem with the Laplacian as principal part subject to a nonlinear boundary condition of Robin type. Under some growth conditions we obtain existence.
