Critical Periods of Perturbations of Reversible Rigidly Isochronous Centers

Abstract and Applied Analysis, 2013
We study the problem of bifurcation of critical periods of a time-reversible polynomial system of degree n. We first present a new method to find the number of zeros of the period function.

Mellin transforms with only critical zeros: generalized Hermite functions [PDF]

, 2013
We consider the Mellin transforms of certain generalized Hermite functions based upon certain generalized Hermite polynomials, characterized by a parameter $\mu>-1/2$.

Zeros of 3F2 hypergeometric polynomials

Journal of Computational and Applied Mathematics, 2001
The zeros of polynomials \(_2F_1[-n, b;c;z]\), where \(b\) is real and \(c\) is \({1\over 2}\) or \({3\over 2}\), have been discussed recently by Driver and Möller [J. Comput. Appl. Math. (to appear). These results are applied in the present paper to investigate the zeros of three \(_3F_2 [z]\) polynomials that are expressible as constant multiples of ...

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

Advanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Zero Asymptotics of Laurent Orthogonal Polynomials

Journal of Approximation Theory, 1996
Let {hn(z)} be the sequence of polynomials, satisfying +0 hm(x) hn(x) x-n dp(x) = mn, 0 m n, where n [0, 2n], n N. For a wide class of weights dp(x) and under the assumption limn n/(2n) = [0, 1], two descriptions of the zero asymptotics of {hn(z)} are obtained.

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Some Inequalities on Polynomials in the Complex Plane Concerning a Linear Differential Operator

Journal of Mathematics
In this paper, we consider new extremal problems in the uniform norm between a univariate complex polynomial and its associated reciprocal polynomial involving a generalized B-operator.

Additive Manufacture of Diamond:Titanium Hybrid Quantum Sensors

Advanced Materials Interfaces, EarlyView.
ABSTRACT Additive manufacture represents one of the most advanced techniques for the creation of complex parts for applications as diverse as aerospace and implant surgery. However, a challenge with bespoke manufacture of metal parts is the incorporation of sensor elements in a fashion compatible with the 3D printing process.

Uniqueness results for differential polynomials sharing a set [PDF]

Mathematica Bohemica
We investigate the uniqueness results of meromorphic functions if differential polynomials of the form $(Q(f))^{(k)}$ and $(Q(g))^{(k)}$ share a set counting multiplicities or ignoring multiplicities, where $Q$ is a polynomial of one variable.
