On Topological Indices of OT [m, n] Octagonal Tillings and TiO2 Nanotubes

open access: yesActa Chimica Slovenica, 2019
Some well defined connectivity topological indices are Randic index, atom-bond connectivity index, geometric-arithmetic index and Shigehalli & Kanabur indices, brought into light by M. Randic, Estrada et al, Vukicevic et al and V. S. Shigehalli, in their

Argument-forms which turn invalid over infinite domains: Physicalism as supertask? [PDF]

open access: yes, 2008
Argument-forms exist which are valid over finite but not infinite domains. Despite understanding of this by formal logicians, philosophers can be observed treating as valid arguments which are in fact invalid over infinite domains.

A degree theory for a class of perturbed Fredholm maps II

open access: yesFixed Point Theory and Applications, 2006
In a recent paper we gave a notion of degree for a class of perturbations of nonlinear Fredholm maps of index zero between real infinite dimensional Banach spaces.

The positive solutions of infinite-point boundary value problem of fractional differential equations on the infinite interval

open access: yesAdvances in Difference Equations, 2017
In this paper, we consider a class of infinite-point boundary value problems of fractional differential equations on the infinite interval [ 0 , + ∞ ) $[0,+\infty)$ with a disturbance parameter.

The cover-index of infinite graphs

open access: yesAequationes Mathematicae, 1980
We show that the cover-index of an infinite graph can be expressed in terms of colouring properties of its finite subgraphs when the minimum degree of the graph is finite. We prove that every simple graph with infinite minimum degreeδ contains a tree which is regular of degreeδ and use this to prove that every graph with minimum degreeδ can be ...

Infinite Ergodic Index of the Ehrenfest Wind-Tree Model [PDF]

open access: yesCommunications in Mathematical Physics, 2017
The set of all possible configurations of the Ehrenfest wind-tree model endowed with the Hausdorff topology is a compact metric space. For a typical configuration we show that the wind-tree dynamics has infinite ergodic index in almost every direction.

A Situational Assessment of the Diagnostic Landscape and Organizational Readiness to Implement Next‐Generation Sequencing at Two Childhood Cancer Treatment Centers in Ghana

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Next‐generation sequencing (NGS) has emerged as a promising approach to improve diagnostic accuracy, but its feasibility in low‐ and middle‐income countries remains unknown. This study characterized the diagnostic landscape and assessed organizational readiness for NGS implementation at two childhood cancer treatment centers in Accra ...

On the automorphism groups of relatively free groups of infinite rank: a survey

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
The paper is intended to be a survey on some topics within the framework of automorphisms of a relatively free groups of infinite rank. We discuss such properties as tameness, primitivity, small index, Bergman property, and so on.
