Imaging of Biphoton States: Fundamentals and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

New Quasi-Coincidence Point Polynomial Problems

open access: yesJournal of Applied Mathematics, 2013
Let F:ℝ×ℝ→ℝ be a real-valued polynomial function of the form F(x,y)=as(x)ys+as-1(x)ys-1+⋯+a0(x), where the degree s of y in F(x,y) is greater than or equal to 1.

Application of Sum-of-Squares Method in Estimation of Region of Attraction for Nonlinear Polynomial Systems

open access: yesIEEE Access, 2020
We present a sum of squares (SOS) method for the synthesis of nonlinear polynomial control systems. As an emerging numerical solution method in recent years, SOS targets polynomials as the research object.

MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

open access: yesAdvanced Functional Materials, EarlyView.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Small solutions of polynomial congruences [PDF]

open access: yesIndian Journal of Pure and Applied Mathematics, 2010
Let \(\delta>0\) be fixed. If \(f(x)\in{\mathbb Z}[x]\) is a polynomial of degree \(\geq p^\delta\) and \(f(x)\equiv 0\pmod p\) has a solution, the author asks whether there is a solution \(x_0\) with \(|x_0|

Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...
