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.

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.

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.

DOI: 10.1088/1742-5468/ae09a4
Abstract: Since the landmark work of Lee and Yang, locating the zeros of the partition function in the complex magnetic-field plane has become a powerful method for studying phase transitions. Fisher later extended this approach to… read more here.

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.

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.

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.
