Published in 2019 at "Journal of Superconductivity and Novel Magnetism"

DOI: 10.1007/s10948-019-05243-0

Abstract: It was found that, in addition to trivial zeros in points (z =  − 2N, N = 1, 2…, natural numbers), the Riemann’s zeta function ζ(z) has zeros only on the line {$$ z=\frac{1}{2}+\mathrm{i}{\mathrm{t}}_0 $$, t0 is real}. All zeros are… read more here.

Published in 2020 at "International Journal of Control"

DOI: 10.1080/00207179.2018.1501609

Abstract: ABSTRACT This paper presents a numerical investigation of three direct architectures and three indirect architectures for identifying a plant operating in closed loop. Motivated by adaptive control of systems with nonminimum-phase (NMP) zeros and taking… read more here.

Published in 2017 at "Journal of Applied Statistics"

DOI: 10.1080/02664763.2016.1193846

Abstract: ABSTRACT For many applications involving compositional data, it is necessary to establish a valid measure of distance, yet when essential zeros are present traditional distance measures are problematic. In quantitative fatty acid signature analysis (QFASA),… read more here.

Published in 2017 at "Experimental Mathematics"

DOI: 10.1080/10586458.2015.1107870

Abstract: ABSTRACT We seek to understand how the technical definition of a Lehmer pair can be related to more analytic properties of the Riemann zeta function, particularly the location of the zeros of ζ′(s). Because we… read more here.

Published in 2022 at "Genome Biology"

DOI: 10.1101/2020.12.28.424633

Abstract: Researchers view vast zeros in single-cell RNA-seq data differently: some regard zeros as biological signals representing no or low gene expression, while others regard zeros as missing data to be corrected. To help address the… read more here.

Published in 2017 at "Physical Review E"

DOI: 10.1103/physreve.95.052145

Abstract: We show that, at the critical temperature, there is a class of Lee-Yang zeros of the partition function in a general scalar field theory, which location scales with the size of the system with a… read more here.

Published in 2019 at "IEEE/ASME Transactions on Mechatronics"

DOI: 10.1109/tmech.2019.2896237

Abstract: A plant with unstable zeros is known to be difficult to be controlled, because of the initial undershoot of its step response and the unstable poles in its inversion system. There are two reasons why… read more here.

Published in 2018 at "Sains Malaysiana"

DOI: 10.17576/jsm-2018-4708-35

Abstract: The presence of extra zeros is commonly observed in traffic accident count data. Past research opt to the zero altered models and explain that the zeros are sourced from under reporting situation. However, there is… read more here.

Published in 2022 at "Symmetry"

DOI: 10.3390/sym14040706

Abstract: This paper intends to define degenerate q-Hermite polynomials, namely degenerate q-Hermite polynomials by means of generating function. Some significant properties of degenerate q-Hermite polynomials such as recurrence relations, explicit identities and differential equations are established.… read more here.
