Multiple limit point bifurcation
Journal of Mathematical Analysis and Applications, 1980 In this paper we present a new bifurcation or branching phenomenon which we call multiple limit point bifurcation. It is of course well known that bifurcation points of some nonlinear functional equation G(u, λ) = 0 are solutions (u_0, λ_0) at which two distinct smooth branches of solutions, say [u(e), λ(e)] and [u^(e), λ^(e)], intersect ...

The lowest point of the continuous spectrum as a bifurcation point
Journal of Differential Equations, 1979 AbstractFor a class of monotone differential operators we show that the lowest point of the continuous spectrum of the linearization is a bifurcation point. By the method of upper and lower solutions we prove the existence of a global branch of positive solutions.

Advanced Science, EarlyView.A self‐powered vibration sensing platform integrates a quasi‐zero‐stiffness piezoelectric harvester, synchronized electric charge extraction, energy management, and wireless ADC acquisition. Ambient vibration is simultaneously harvested as energy and digitized as information, enabling sustained real‐time waveform monitoring without external power.

Advanced Science, EarlyView.A pH‐switchable cerium single‐atom enzyme is developed for stage‐specific peri‐implantitis therapy. Acidic conditions trigger antibacterial peroxidase‐like activity, whereas neutral conditions activate an antioxidant superoxide dismutase ‐ and catalase ‐like enzymatic relay. This microenvironment‐adaptive catalytic strategy suppresses the IL‐6/JAK‐STAT

On the number of branches of bifurcation points
Kodai Mathematical Journal, 1992 In this paper the branching behaviour for multiparameter bifurcation is investigated. The main issue is to give the precise number of bifurcating branches. The authors concentrate on the case with two parameters, i.e. let \(f:\mathbb{R}^ n\times\mathbb{R}^ 2\to\mathbb{R}^ n\). Define the nontrivial set of solutions to be those of the form \((x,\lambda)\

Neuromorphic Devices and Computing for Sensing, Memory, and Control
Advanced Science, EarlyView.This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Advanced Science, EarlyView.This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...
