Accumulated dose stability parameters in p-type and n-type silicon diodes

Brazilian Journal of Radiation Sciences
This work investigates the influence of doping type on the dose responses and the accumulated dose stability of n- and p-type silicon MCz diodes. The operating principle of diode-based dosimeters relies on measuring the radiation-induced currents ...

On Polar Jacobi Polynomials

Mathematics
In the present work, we investigate certain algebraic and differential properties of the orthogonal polynomials with respect to a discrete–continuous Sobolev-type inner product defined in terms of the Jacobi measure.

Inequalities for the Polar Derivatives of a Polynomial

Analysis in Theory and Applications, 2014
Let $P(z)$ be a polynomial of degree $n,$ having all its zeros in $|z|\leq 1.$ In this paper, we estimate $kth$ polar derivative of $P(z)$ on $|z|=1$ and thereby obtain compact generalizations of some known results which among other things yields a refinement of a result due to Paul Turán.

Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

Advanced Electronic Materials, EarlyView.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Polar permutation graphs are polynomial-time recognisable

European Journal of Combinatorics, 2013
Polar graphs generalise bipartite graphs, cobipartite graphs, and split graphs, and they constitute a special type of matrix partitions. A graph is polar if its vertex set can be partitioned into two, such that one part induces a complete multipartite graph and the other part induces a disjoint union of complete graphs.

A note on the zeros of polar derivative of a polynomial

Malaya Journal of Matematik, 2020
In $[4,7]$, Enestrom Kakeya theorem has stated as the following. If $f(z)=\sum_{j=0}^n k_j z^j$ is the $n^{t h}$ degree polynomial with real coefficients such that $0<k_0 \leq k_1 \leq \ldots \leq k_{n-2} \leq k_{n-1} \leq k_n$ then all zeros of $\mathrm{f}(\mathrm{z})$ lies in $|z| \leq 1$.

Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT

Advanced Electronic Materials, EarlyView.
Scan trajectory and initial superdomain topology govern polarization switching in (111)‐oriented PZT. Automated AFM writing, pulsing experiments, and interferometric 3D‐PFM show that raster scans reproducibly stabilize ordered Type‐I stripe superdomains with constrained variant selection, whereas spiral trajectories generate frustrated mixed‐variant ...

Inequalities for the polar derivative of a polynomial

Journal of Approximation Theory, 1988
Let \(D_{\alpha}P(z)\) denote the polar differentiation of the polynomial \(P(z)\) of degree \(n\) with respect to the point \(\alpha\), i.e. \(D_{\alpha}P(z)=nP(z)+(\alpha -z)P'(z)\). In this paper several inequalities of Bernstein type for complex polynomials are generalized to the case of the polar differentiation.
