Bifurcation analysis of fractional Kirchhoff–Schrödinger–Poisson systems in $\mathbb R^3$

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we investigate the bifurcation results of the fractional Kirchhoff–Schrödinger–Poisson system \begin{equation*} \begin{cases} M([u]_s^2)(-\Delta)^s u+V(x)u+\phi(x) u=\lambda g(x)|u|^{p-1}u+|u|^{2_s^*-2}u~~&{\rm in}~\mathbb{R}^3, \\

Activation‐Integrated and Memory‐Assisted Dynamic‐Latch Quantizer for Variation‐Tolerant and Low‐Energy Neuromorphic Computing

Advanced Intelligent Systems, EarlyView.
A memory‐assisted dynamic‐latch ADC integrating charge‐trap flash enables ultra‐low‐energy quantization and in‐ADC nonlinear activation for variation‐tolerant neuromorphic computing. Analog‐to‐digital converters (ADCs) remain the dominant area/energy bottleneck in neuromorphic computing (NC) systems.

Blow-up and lifespan of solutions for elastic membrane equation with distributed delay and logarithmic nonlinearity

Boundary Value Problems
We examine a Kirchhoff-type equation with nonlinear viscoelastic properties, characterized by distributed delay, logarithmic nonlinearity, and Balakrishnan–Taylor damping terms (elastic membrane equation).

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Ground state solution of a nonlocal boundary-value problem

, 2013
In this paper, we apply the method of the Nehari manifold to study the Kirchhoff type equation \begin{equation*} -\Big(a+b\int_\Omega|\nabla u|^2dx\Big)\Delta u=f(x,u) \end{equation*} submitted to Dirichlet boundary conditions.

Thermochromic Radiative Cooling Coatings with Robust Superhydrophobicity for Energy‐Efficient Buildings

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable, color‐adaptive radiative cooling coating is developed to enable dynamic spectral regulation via a reversible thermochromic transition at ~45 °C and a high solar reflectance of 91.7%. The coating achieves 4.44 °C outdoor sub‐ambient cooling while providing robust superhydrophobicity and environmental durability through its micro/nano ...

Normalized solutions for Kirchhoff-type equations with combined nonlinearities: the $L^2$-critical case

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we consider the existence of normalized solutions for the following Kirchhoff-type problem: \begin{equation*} -\left (a+b\int_{\mathbb{R}^{N}}|\nabla u|^{2}dx\right)\Delta u=\lambda u+|u|^{p-2}u+\mu |u|^{q-2}u\quad \mbox{in} \ \mathbb{R}^{

Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

Nonlinear perturbations of the Kirchhoff equation

Electronic Journal of Differential Equations, 2017
In this article we study the existence and uniqueness of local solutions for the initial-boundary value problem for the Kirchhoff equation $$\displaylines{ u'' - M(t,\|u(t)\|^{2})\Delta u + |u|^{\rho} =f \quad\text{in } \Omega \times (0, T_0), \cr u=

Resonance problems for Kirchhoff type equations

Discrete & Continuous Dynamical Systems - A, 2013
The existence of weak solutions is obtained for some Kirchhoff type equations with Dirichlet boundary conditions which are resonant at an arbitrary eigenvalue under a Landesman-Lazer type condition by the minimax methods.
