SOME RECURRENCE RELATIONS OF MULTIPLE ORTHOGONAL POLYNOMIALS [PDF]

Journal of the Korean Mathematical Society, 2005
Multiple orthogonal polynomial systems (OPS) are considered. A sequence of polynomial vectors \(\{(A_{(n_1,n_2)}, B_{(n_1,n_2)})\}\) is called a multiple OPS of type I relative to a pair of measures \((d\mu,d\nu)\) if (i) \(\deg A_{(n_1,n_2)}=n_1\) and \(\deg B_{(n_1,n_2)}=n_2\); (ii) \(\int_{\mathbb R}x^k (A_{(n_1,n_2)}\, d\mu+ B_{(n_1,n_2)}\,d\nu)=0\)

Christoffel functions for multiple orthogonal polynomials

Journal of Approximation Theory, 2022
We study weak asymptotic behaviour of the Christoffel--Darboux kernel on the main diagonal corresponding to multiple orthogonal polynomials. We show that under some hypotheses the weak limit of $\tfrac{1}{n} K_n(x,x)\, dμ$ is the same as the limit of the normalized zero counting measure of type II multiple orthogonal polynomials.

Legendre Cooperative PSO Strategies for Trajectory Optimization

Complexity, 2018
Particle swarm optimization (PSO) is a population-based stochastic optimization technique in a smooth search space. However, in a category of trajectory optimization problem with arbitrary final time and multiple control variables, the smoothness of ...

Analyzing genotype-by-environment interaction using curvilinear regression

Scientia Agricola, 2012
In the context of multi-environment trials, where a series of experiments is conducted across different environmental conditions, the analysis of the structure of genotype-by-environment interaction is an important topic.

Efficient Charge Transport in Zero‐Dimensional Perovskite for Ultrahigh‐Sensitivity X‐Ray Detection

Advanced Functional Materials, EarlyView.
A novel mono‐octahedral 0D Bi‐based Dpy3Bi2I12 perovskite strengthens the internal hydrogen bonds and forms a quasi‐2D lattice, exhibits exceptional charge transport and mobility, achieving high X‐ray sensitivity and ultralow‐dose imaging, and setting a new benchmark for 0D detector performance.

Linear-algebraic bath transformation for simulating complex open quantum systems

New Journal of Physics, 2014
In studying open quantum systems, the environment is often approximated as a collection of non-interacting harmonic oscillators, a configuration also known as the star-bath model. It is also well known that the star-bath can be transformed into a nearest-

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.
