We present explicit formulae for the eccentric connectivity index and Wiener index of 2-dimensional square and comb lattices with open ends. The formulae for these indices of 2-dimensional square lattices with ends closed at themselves are also derived. The index for closed ends case divided by the same index for open ends case in the limit N →&infin defines a novel quantity we call compression...

BACKGROUND There is increasing recognition that pulmonary artery stiffness is an important determinant of right ventricular (RV) afterload in pulmonary arterial hypertension (PAH). We used intravascular ultrasound (IVUS) to evaluate the mechanical properties of the elastic pulmonary arteries (PA) in subjects with PAH, and assessed the effects of PAH-specific therapy on indices of arterial stiff...

We derived explicit formulae for the eccentric connectivity index and Wiener index of 2-dimensional square-octagonal TUC4C8(R) lattices with open and closed ends. New compression factors for both indices are also computed in the limit N-->∞.

A vast amount of indices has been proposed in the literature [1] to quantify the deviation of a pairwise comparison matrix A = (aij)n×n from the consistency property aik = aijajk ∀i, j, k. In this paper we propose a unifying approach by expressing an inconsistency index as a function of the matrix entries aij satisfying a set of suitable properties. More precisely, we first consider the ‘local’...

in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...

background: health status of children and adolescents is determined to a larger extent by their nutritional status. there are no published studies available on the influence of thinness on childhood morbidity using new world health organization‑body mass index (who‑bmi) for age criteria. methods: this cross‑sectional study was conducted in primary, high schools, pre‑university and degree colleg...

AIMS/INTRODUCTION To define a set of criteria using indices of β-cell function, including results from the glucagon stimulation test, for liraglutide introduction in patients with type 2 diabetes. MATERIALS AND METHODS In the present retrospective cohort study, patients were included in our analysis if their β-cell function had been evaluated with a glucagon stimulation test and a 24-h urinar...

Advances in the management of rheumatoid arthritis (RA) have rendered remission an increasingly achievable goal. However, a single, universal definition of remission in RA does not exist. Remission criteria were developed in 1981 by a committee of the American College of Rheumatology (ACR) and have been described according to different composite indices. In 2011, a committee of the ACR and the ...

This paper features a tri-criteria analysis of Eurekahedge fund data strategy index data. We use nine Eurekahedge equally weighted main strategy indices for the portfolio analysis. The tri-criteria analysis features three objectives: return, risk and dispersion of risk objectives in a Multi-Criteria Optimisation (MCO) portfolio analysis. We vary the MCO return and risk targets and contrast the ...
