Distortion product otoacoustic emissions: challenging existing theory
, 2010 Distortion product otoacoustic emissions (DPOAE or DP) are generated using two primary tones at frequencies f1 and f2 at levels L1 and L2; the two most prominent DP are cubic distortion products at the frequencies 2f1f2 and 2f2f1.

Advanced Science, EarlyView.As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

MULTIVALENT α - CONVEX HARMONIC MAPPINGS
Проблемы анализа, 2002 In this paper we give coefficient conditions for complex-valued harmonic functions that are ultivalent, sense-preserving and α-convex. We determine the extreme points, distortion and covering theorems for these mappings.

Advanced Science, EarlyView.Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.

A distortion theorem for quasiconformal mappings [PDF]
Bulletin de la Société mathématique de France, 1986 There exists a constant \(C=C(K,n)\) such that for any K-quasiconformal mapping \(f: B^ n\to {\mathbb{R}}^ n\) and for any \(z\in B\) there exists \(x\in \partial B^ n\) with \(| z-x| 1) \] where \(f^*\) is the nontangential maximal function.

Some theorems on boundary distortion [PDF]
Transactions of the American Mathematical Society, 1956 one. 2. Our method of treating these results is in all cases what may be called the method of the extremal metric. It is essentially the method used to such advantage by Gr6tzsch, however we use the more convenient formulation due to Ahlfors and Beurling.

TWO-POINT DISTORTION THEOREMS FOR HARMONIC MAPPINGS
, 2009 In earlier work, the authors have extended Nehari's well-known Schwarzian derivative criterion for univalence of analytic functions to a univalence criterion for canonical lifts of harmonic mappings to minimal surfaces.

Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers
Advanced Science, EarlyView.This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Angewandte Chemie, EarlyView.In this work, we establish a direct correlation between internal compactness and particle architectural stability, identifying it as a key descriptor of cathode structural integrity. Simultaneously, the capacity contribution and compensation mechanism of ARR are resolved, revealing that the extent of irreversible capacity loss is governed by both the ...
