This paper bears on the comparison of two well-known metrics between linear orders called the Kendall and Spearman metrics or/and of their normalized versions respectively known as the Kendall tau and the Spearman rho. Using a combinatorial approach based on the partial order intersection of the two compared linear orders, we first prove a relation between these two metrics and a semi-metric, e...

drought monitoring and evaluation in water resources systems, are basic steps in systems analysis aswell as the optimal water resources allocation for different demands. therefore, in this study, whole of irancountry was selected as the study area, and it was attempted to determine the simultaneous droughts whichhad been occurred in the period of 1981-2010, using monthly rainfall data of 31 syn...

BACKGROUND Although Bone morphogenetic protein-2 (BMP-2) is a known mediator of bone regeneration and vascular calcification, to date no study has investigated the relationship between BMP-2 and type 2 diabetes mellitus (T2DM) and its possible role in coronary artery disease (CAD). The purpose of this study is to evaluate the relationship of BMP-2 with atherosclerosis and calcification in patie...

BACKGROUND The internet introduces new ways to deal with stress. However, it is unclear how its resources are used in everyday life. Using a web-based personal health record (PHR), we observed the patient's online behaviour and linked this to distress, theories on dealing with stress and demographics. METHODS Between 2004 and 2007, all viewed web-pages were logged and categorized into 14 cont...

OBJECTIVE To develop a standardized validated version of the Hamilton Rating Scale for Depression (HAM-D) in Urdu. METHODS After translation of the HAM-D into the Urdu language following standard guidelines, the final Urdu version (HAM-D-U) was administered to 160 depressed outpatients. Inter-item correlation was assessed by calculating Cronbach alpha. Correlation between HAM-D-U scores at ba...

The aim of this study was to assess the validity of micro-spatial dentine lead (Pb) levels as a biomarker for accurately estimating exposure timing over the prenatal and early childhood periods and long-term cumulative exposure to Pb. In a prospective pregnancy cohort sub-sample of 85 subjects, we compared dentine Pb levels measured using laser ablation-inductively coupled plasma mass spectrome...

PURPOSE The level of the implant above the marginal bone and flap design have an effect on the bone resorption during the healing period. The aim of this study is to detect the relationship between the level of the implant at the implant placement and the bone level at the healing period in the mesial and distal side of implants placed with flapless (FL) and full-thickness flap (FT) methods. ...

BACKGROUND Efforts to improve the diagnosis, prognosis and surveillance of prostate cancer (PCa) are relevant. Gleason score (GSc) overestimation may subject individuals to unnecessary aggressive treatment. We aimed to use stereology in PCa evaluations and investigate whether mean nuclear volume (MNV) correlates with the Gleason primary pattern (Gpp) and to improve the subjective GSc to obtain ...
