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.

The Herschel view of the dominant mode of galaxy growth from z=4 to the present day [PDF]

open access: yes, 2015
We present an analysis of the deepest Herschel images in four major extragalactic fields GOODS-North, GOODS-South, UDS and COSMOS obtained within the GOODS-Herschel and CANDELS-Herschel key programs.

Differential rotation of Kepler-71 via transit photometry mapping of faculae and starspots [PDF]

open access: yes, 2019
Knowledge of dynamo evolution in solar-type stars is limited by the difficulty of using active region monitoring to measure stellar differential rotation, a key probe of stellar dynamo physics.

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

open access: yesJournal 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

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

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.

Low X-Ray Luminosity Galaxy Clusters. II. Optical properties and morphological content at 0.18 < z < 0.70 [PDF]

open access: yes, 2013
This is the second of a series of papers on low X-ray luminosity galaxy clusters, in which we present the $r^\prime$, $g^\prime$ and $i^\prime$ photometry obtained with GMOS-IMAGE at Gemini North and South telescopes for seven systems in the redshift ...

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
