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

Discrete 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

Agriculture, 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.

Perfect simulation of a coupling achieving the $\bar{d}$-distance between ordered pairs of binary chains of infinite order [PDF]

, 2010
We explicitly construct a coupling attaining Ornstein's $\bar{d}$-distance between ordered pairs of binary chains of infinite order. Our main tool is a representation of the transition probabilities of the coupled bivariate chain of infinite order as a ...

On the quasi-monotone and almost increasing sequences [PDF]

Journal of Mathematical Inequalities, 2007
In this paper, a theorem of Bor and ¨ Ozarslan (3) dealing with | C,α;β |k summability factors has been generalized for | C,α,γ;β | k summability methods.

Quasi β-power increasing sequences

International 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

mSphere, 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

Genome signatures, self-organizing maps and higher order phylogenies: a parametric analysis [PDF]

, 2007
Genome signatures are data vectors derived from the compositional statistics of DNA. The self-organizing map (SOM) is a neural network method for the conceptualisation of relationships within complex data, such as genome signatures.

A new application of almost increasing sequences [PDF]

Miskolc 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.

A Revised Parallel-Sequence Morphological Classification of Galaxies: Structure and Formation of S0 and Spheroidal Galaxies [PDF]

, 2011
We update van den Bergh's parallel sequence galaxy classification in which S0 galaxies form a sequence S0a-S0b-S0c that parallels the sequence Sa-Sb-Sc of spiral galaxies.

Programming Language Feature Agglomeration [PDF]

, 2014
Feature-creep is a well-known phenomenon in software systems. In this paper, we argue that feature-creep also occurs in the domain of programming languages. Recent languages are more expressive than earlier languages.
