Application for a Novel Perturbation Expansion Method

open access: yesJournal of Algorithms & Computational Technology, 2009
We formulate a coupled vibration problem between a structure and an acoustic field by FEM (finite element methods). The problem leads to a nonstandard eigenvalue problem.

Dancing Electrohydrodynamic Tip Streaming Modulated by Faraday Instability

open access: yesAdvanced Science, EarlyView.
A novel dancing electrospray phenomenon is reported characterized by high‐frequency, robust, and multi‐directional alternating ejection modes. This phenomenon arises from the electrohydrodynamic (EHD) tip streaming at the crests of Faraday waves excited on the liquid meniscus, and it offers significant advantages in high‐throughput and multi‐path ...

Switchable Bidirectional Sound Absorption Via Exceptional Point Modulation in Acoustic Metastructures with Interleaved Resonator Coupling

open access: yesAdvanced Science, EarlyView.
A switchable bidirectional acoustic metastructure is proposed, enabling broadband and frequency‐selective absorption via interleaved resonator coupling and exceptional point modulation. It outperforms traditional unidirectional designs, offering compact, efficient sound control from both directions and establishing a generalized framework for extending

A Programmable, 3D Neuron‐On‐Chip Platform Integrating Near Real‐Time Biosensing and Multiaxial Loading for Mechanobiological Injury Profiling

open access: yesAdvanced Science, EarlyView.
A programmable 3D Neuron‐Injury‐on‐a‐Chip platform integrates multiaxial mechanical loading with ultrasensitive electrochemical biosensing to decode neuronal responses in real time. By mimicking physiologically relevant extension–torsion forces, the system reveals load‐specific biomarker trajectories (T‐Tau, NFL), gene regulation, and apoptosis.

Dynamic behavior analysis of a prey-predator model with ratio-dependent Monod-Haldane functional response

open access: yesOpen Mathematics, 2018
This paper investigates the dynamic behavior analysis on the prey-predator model with ratio-dependent Monod-Haldane response function under the homogeneous Dirichlet boundary conditions, which is used to simulate a class of biological system.

Nongeneric eigenvalue perturbations of Jordan blocks

open access: yesLinear Algebra and its Applications, 1998
Conditions under which a Jordan block is perturbed are presented. The nontypical behaviour of the eigenvalues split up into some rings of different sizes is studied.

Intracellular Mechanical Stress‐Mediated Autophagy Cell Death via Nanospikes for Cancer Treatment

open access: yesAdvanced Science, EarlyView.
Nanospikes with tunable morphology at the nanoscale induce lysosomal membrane damage by generating localized mechanical stress, activating Galectin‐3 (Gal3)‐Trim16‐mediated autophagic cell death. Finite element analysis and laser‐triggered spike ablation enable precise control of intracellular force signaling and cytotoxicity, offering a ...

Toward efficient quantum computation of molecular ground‐state energies

open access: yesAIChE Journal, EarlyView.
Abstract Variational quantum eigensolvers (VQEs) represent a promising approach to computing molecular ground states and energies on modern quantum computers. These approaches use a classical computer to optimize the parameters of a trial wave function, while the quantum computer simulates the energy by preparing and measuring a set of bitstring ...

Dissipative systems with nonlocal delayed feedback control

open access: yesNew Journal of Physics, 2018
We present a linear model, which mimics the response of a spatially extended dissipative medium to a distant perturbation, and investigate its dynamics under delayed feedback control.
