An extremal problem for a graphic sequence to have a realization containing every 2-tree with prescribed size [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
A graph $G$ is a $2$-tree if $G=K_3$, or $G$ has a vertex $v$ of degree 2, whose neighbors are adjacent, and $G-v$ is a 2-tree. Clearly, if $G$ is a 2-tree on $n$ vertices, then $|E(G)|=2n-3$.

Sequential Action of Different Fiber-Degrading Enzymes Enhances the Degradation of Corn Stover

open access: yesAgriculture, 2022
Corn stover is one of the most agricultural residue abundances over the world; however, it is extremely prevented from microbial and enzymatic degradation into monomers because of the complex chemical and physical structure.

A new application of almost increasing sequences [PDF]

open access: yesMiskolc Mathematical Notes, 2013
In the present paper we have proved a more general theorem dealing with vertical bar A, p(n)vertical bar(k) summability by using almost increasing sequence. This theorem also includes several known results.

Maximal increasing sequences in fillings of almost-moon polyominoes [PDF]

open access: yesAdvances in Applied Mathematics, 2015
It was proved by Rubey that the number of fillings with zeros and ones of a given moon polyomino thatdo not contain a northeast chain of a fixed size depends only on the set of column lengths of the polyomino. Rubey’sproof uses an adaption of jeu de taquin and promotion for arbitrary fillings of moon polyominoes and deduces theresult for 01-fillings ...

Quasi β-power increasing sequences

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We prove a theorem of Mazhar (1999) on |N¯,pn|k summability factors under weaker conditions by using a quasi β-power increasing sequence instead of an almost increasing sequence.

Rampant C→U Hypermutation in the Genomes of SARS-CoV-2 and Other Coronaviruses: Causes and Consequences for Their Short- and Long-Term Evolutionary Trajectories

open access: yesmSphere, 2020
The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has motivated an intensive analysis of its molecular epidemiology following its worldwide spread. To understand the early evolutionary events following its emergence, a data set

Quasimonotone and Almost Increasing Sequences and Their New Applications [PDF]

open access: yesAbstract and Applied Analysis, 2012
Recently, we have proved a main theorem dealing with the absolute Nörlund summability factors of infinite series by using δ‐quasimonotone sequences. In this paper, we prove that result under weaker conditions. A new result has also been obtained.

Noise-proof method for determining the linear dynamic system parameters based on pulse-response characteristic

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We consider the method for parametric identification of the linear dynamic system based on the stochastic difference equation describing the sequence of the measurements of instantaneous values of system pulse-response characteristics.

Early evolution of conserved regulatory sequences associated with development in vertebrates. [PDF]

open access: yesPLoS Genetics, 2009
Comparisons between diverse vertebrate genomes have uncovered thousands of highly conserved non-coding sequences, an increasing number of which have been shown to function as enhancers during early development. Despite their extreme conservation over 500
