Nonaxisymmetric Magnetorotational Instability in Proto-Neutron Stars

, 2005
We investigate the stability of differentially rotating proto-neutron stars (PNSs) with a toroidal magnetic field. Stability criteria for nonaxisymmetric MHD instabilities are derived using a local linear analysis. PNSs are expected to have much stronger

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

Advanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

Advanced Materials, EarlyView.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.

Some oscillation criteria for difference equations

Computers & Mathematics with Applications, 2000
Consider the difference equation \[ x_{n+1}- x_n+p_nx_{n-k}=0, \quad n=0,1,2, \dots\tag{1} \] where \(\{p_n\}\) is a sequence of nonnegative real numbers and \(k\) is a positive integer. New sufficient conditions for the oscillation of all solutions of (1) are established.
