On BF-orderable graphs

open access: yesDiscrete Applied Mathematics, 1986
A directed graph G is BF-orderable w.r.t. a vertex s if there exists an ordering of the edges such that on any simple path starting from s the edges occur increasingly. This generalization of acyclic graphs enables a linear time algorithm for the single source shortest path problem. An entry point (w.r.t. s) of a subgraph S of G is a vertex w of S s.t.

Growth and root respiration of C4 plants under CO2 enrichment

open access: yesActa Biologica Slovenica, 2003
Respiratory measurements of apical root parts of several C4 plant species (Echinochloa crus-galli var. crus-galli, Setaria pumila and Zea mays DK 312 (Dekalb, USA) subjected to an elevated CO2 regime during growth in climatic chambers or at natural CO2 ...

Upper and lower densities have the strong Darboux property [PDF]

open access: yes, 2016
Let $\mathcal{P}({\bf N})$ be the power set of $\bf N$. An upper density (on $\bf N$) is a non\-decreasing and subadditive function $\mu^\ast: \mathcal{P}({\bf N})\to\bf R$ such that $\mu^\ast({\bf N}) = 1$ and $\mu^\ast(k \cdot X + h) = \frac{1}{k} \mu^\

Physicochemical characterization of dual action liposomal formulations: anticancer and antimicrobial

open access: yesHeliyon, 2019
Background: Cancer till date remains one of the world's most life threatening disease accompanied by risk of secondary infections. Therefore formulations carrying anticancer drugs which can also decrease the risk of secondary infection are inevitable ...

Anti-Aging Effects of Monomethylsilanetriol and Maltodextrin-Stabilized Orthosilicic Acid on Nails, Skin and Hair

open access: yesCosmetics, 2018
Chemical form of silicon determines its absorption and bioavailability: particulate and polymerized forms exhibit minimal oral bioavailability, while monomers (maltodextrin-stabilized orthosilicic acid, M-OSA) and organic compounds (monomethylsilanetriol,

Perturbative BF theory

open access: yesNuclear Physics B, 2020
We consider a superrenormalisable gauge theory of topological type, in which the structure group is equal to the inhomogeneous group ISU(2). The generating functional of the correlation functions of the gauge fields is derived and its connection with the

Convolution of orbital measures on symmetric spaces of type $C_p$ and $D_p$ [PDF]

open access: yes, 2014
We study the absolute continuity of the convolution $\delta_{e^X}^\natural \star\delta_{e^Y}^\natural$ of two orbital measures on the symmetric spaces ${\bf SO}_0(p,p)/{\bf SO}(p)\times{\bf SO}(p)$, $\SU(p,p)/{\bf S}({\bf U}(p)\times{\bf U}(p))$ and $\Sp(

Efficient Approaches for Enclosing the United Solution Set of the Interval Generalized Sylvester Matrix Equation

open access: yes, 2015
In this work, we investigate the interval generalized Sylvester matrix equation ${\bf{A}}X{\bf{B}}+{\bf{C}}X{\bf{D}}={\bf{F}}$ and develop some techniques for obtaining outer estimations for the so-called united solution set of this interval system ...
