Connected even factors in k-tree

open access: yesOpen Mathematics, 2020
A connected even [2,2s]{[}2,2s]-factor of a graph G is a connected factor with all vertices of degree i(i=2,4,…,2s)i(i=2,4,\ldots ,2s), where s≥1s\ge 1 is an integer. In this paper, we show that a k+1s+2\tfrac{k+1}{s+2}-tough k-tree has a connected even [

High-resolution soil erodibility K-factor estimation using machine learning generated soil dataset and soil pH levels [PDF]

open access: yesGeodesy and Cartography, 2021
Soil Erodibility Factor (K-factor) is a crucial component of a widely used equation for soil erosion assessment known as the USLE (Universal Soil Loss Equation) or its revised version – RUSLE.

The planted k-factor problem [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2021
Abstract We consider the problem of recovering an unknown k-factor, hidden in a weighted random graph. For k = 1 this is the planted matching problem, while the k = 2 case is closely related to the planted traveling salesman problem.

Effects of parent material on soil properties and soil erodibility: The case study of Cemrengec watershed

open access: yesTurkish Journal of Forestry, 2021
Erodibility is a property that results from the various properties of soils in their own structure and shows their resistance to erosive factors or their tendency to erosion.

Comparative analysis of discrete exosome fractions obtained by differential centrifugation [PDF]

open access: yesJournal of Extracellular Vesicles, 2014
Background: Cells release a mixture of extracellular vesicles, amongst these exosomes, that differ in size, density and composition. The standard isolation method for exosomes is centrifugation of fluid samples, typically at 100,000×g or above. Knowledge

Biodistribution and respiratory toxicity of chloromethylisothiazolinone/methylisothiazolinone following intranasal and intratracheal administration

open access: yesEnvironment International, 2022
A variety of isothiazolinone-containing small molecules have been registered and used as chemical additives in many household products. However, their biodistribution and potential harmful effects on human health, especially respiratory effects, were not

Improved design of LED lamp circuit to enhance distribution transformer capability based on a comparative study of various standards

open access: yesEnergy Reports, 2022
Nowadays, light-emitting diode (LED) lamps replaced the conventional types because of its higher brightness and lower energy consumption. The lamps represent about 20% of the total load all over the world.
