A parallel algorithm for the eigenvalues and eigenvectors for a general complex matrix [PDF]
A new parallel Jacobi-like algorithm is developed for computing the eigenvalues of a general complex matrix. Most parallel methods for this parallel typically display only linear convergence. Sequential norm-reducing algorithms also exit and they display

A Van der Waals Material Exhibiting Room Temperature Broken Inversion Symmetry with Ferroelectricity
Advanced Science, EarlyView.This study reports a βp$\ubeta^{\text{p}}$ phase of indium selenide showing ferroelectricity over large areas at room temperature in a low‐dimensional limit. It is found that indium selenide films with βp$\ubeta^{\text{p}}$ layers display electric field‐induced switchable polarization characteristic of ferroelectric materials, suggesting the breaking ...

New Results on the Quasilinearization Method for Time Scales
MathematicsWe have developed the generalized quasilinearization method (QM) for an initial value problem (IVP) of dynamic equations on time scales by using comparison theorems with a coupled lower solution (LS) and upper solution (US) of the natural type.

Advanced Science, EarlyView.Low‐frequency noise fingerprints in hafnia ferroelectrics provide a quantitative handle to resolve the long‐standing debate between polarization‐mediated and defect‐mediated switching. By tuning oxygen vacancy density via ALD O3 dose time and applying a physically constrained deconvolution, we extract bias‐resolved current fractions for both mechanisms

Quasilinearization method for first-order impulsive integro-differential equations
Electronic Journal of Differential Equations, 2019 In this article we study first-order impulsive integro-differential equations with integral boundary conditions, employing the method of quasilinearization with reversed ordering upper and lower solutions.

The nonlinear limit control of EDSQOs on finite dimensional simplex
Automatika, 2019 Consensus problems in multi agent systems (MAS) are theoretical aspect convergence of doubly stochastic quadratic operators. This work has presented the dynamic classifications of extreme doubly stochastic quadratic operators (EDSQOs) on finite ...

Advanced Science, EarlyView.This study elucidates mass transport dynamics within polybromide ionic liquids in dual‐plating zinc–bromine batteries using operando impedance spectroscopy. The findings reveal that sluggish polybromide transport during dissolution contrasts with rapid bromide transport during charging.

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, EarlyView.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...
