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

On the distribution of the eigenvalues of a class of indefinite eigenvalue problems

open access: yesDifferential and Integral Equations, 1990
The authors consider boundary eigenvalue problems of the form \[ y^{(n)}(x)+\sum^ n_{\nu=2}f_ \nu(x)y^{(n-\nu)}(x)=\lambda r(x)y(x)\qquad (x\in[0,1]), \] \[ U_{\nu0}(y)+U_{\nu1}(y)=0\qquad (\nu=1,2,\dots,n), \] where \(n\geq 2\), the coefficients \(f_ \nu\) belong to \(L_ 1(0,1)\), \(r:[0,1]\to\mathbb{R}\backslash\{0\}\) is a step function, and the two-

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.

Unambiguous Quantum State Discrimination in a PT$\mathcal {PT}$‐Symmetric System of a Single Trapped Ion

open access: yesAdvanced Science, EarlyView.
An unambiguous quantum state discrimination for two nonorthogonal states is demonstrated using a single ion. By implementing a non‐Hermitian Hamiltonian with parity‐time‐reversal (PT) symmetry, two candidate states evolve with different speed and become orthogonal at specific time, hence can be discriminated unambiguously. Experiments are performed for

Spectra of Graphs Resulting from Various Graph Operations and Products: a Survey

open access: yesSpecial Matrices, 2018
Let G be a graph on n vertices and A(G), L(G), and |L|(G) be the adjacency matrix, Laplacian matrix and signless Laplacian matrix of G, respectively. The paper is essentially a survey of known results about the spectra of the adjacency, Laplacian and ...

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 ...
