a r t i c l e i n f o Keywords: Foster care Juvenile delinquency Neighborhood characteristics Neighborhood social process This study aims to advance the knowledge base by investigating where foster youth are placed in terms of neighborhood characteristics and whether specific neighborhood characteristics were associated with delinquency for adolescents in the child welfare system. This study fo...

The inverse monodromic (or isomonodromic) transformation (IMT) method [1, 2] is a powerful tool for studying the class of nonlinear ordinary differential equations (ODE’s) representable as the compatibility condition of the overdetermined linear system (P–Q pair). The IMT method reduces the initial value problem for the system of nonlinear ODE’s to solving the inverse problem for associated iso...

The eukaryotic tRNA:guanine transglycosylase (TGT) catalyses the base-for-base exchange of guanine for queuine (the q-base)--a nutrition factor for eukaryotes--at position 34 of the anticodon of tRNAsGUN (where 'N' represents one of the four canonical tRNA nucleosides), yielding the modified tRNA nucleoside queuosine (Q). This unique tRNA modification process was investigated in HeLa cells grow...

A new dinuclear cadmium(II) complex, [Cd(L)(NCS)]2 (1) has been synthesized using a potentially tetradentate Schiff base ligand HL, 2-((E)-(2-(diethylamino)ethylimino)methyl)-6-methoxyphenol, obtained by the condensation of 2-diethylaminoethylamine and o-vanillin, and characterized by different physicochemical techniques. Crystal structure of the title complex was unambiguously established by s...

This paper is concerned with scal externalities arising from local taxation of a mobile factor. Using a panel of more 1100 local jurisdictions it provides empirical evidence on how the local tax rate as well as the tax rate in the neighborhood a ect the local tax base. The results support the existence of scal externalities: an increase in the tax rate of local neighbors exerts a positive e ect...

The k-NN graph has played a central role in increasingly popular data-driven techniques for various learning and vision tasks; yet, finding an efficient and effective way to construct k-NN graphs remains a challenge, especially for large-scale high-dimensional data. In this paper, we propose a new approach to construct approximate k-NN graphs with emphasis in: efficiency and accuracy. We hierar...

Let D(p, q) be a digraph. A function f: V → {1, 2, ..., n} is said to neighborhood prime labeling of D if it both in and out degree labeling. In this paper, we introduce the concept digraphs also investigate existence some digraphs.

Abstract In this paper, by using q -calculus (Jackson’s -derivative) $$D_{q,p}$$ D q , p we defined new operator $$D_{\lambda ,q,p}^{n}f^{(m)}(z)$$ λ n </mml:msubsup...

A conjecture of AutoGraphiX on the relation between the Randić index R and the algebraic connectivity a of a connected graph G is: R a ≤ ( n− 3 + 2√2 2 ) / ( 2(1− cos π n ) ) with equality if and only if G is Pn, which was proposed by Aouchiche et al. [M. Aouchiche, P. Hansen and M. Zheng, Variable neighborhood search for extremal graphs 19: further conjectures and results about the Randić inde...
