Discovering densely-populated regions in a dataset of data points is an essential task for density-based clustering. To do so, it often necessary to calculate each point’s local density the dataset. Various definitions have been proposed literature. These can be divided into two categories: Radius-based and k Nearest Neighbors-based. In this study, we find commonality between these types propos...

in this study, effect of two genotype imputation strategies, relatedness between reference panel and test populations and minor allele frequency on imputation error rate were examined with using a stochastic simulated population. reference panel and test populations were composed of 1,000 and 500 individuals, respectively. individuals in the reference panel were genotyped with using a high and ...

conclusions psa, psa density, and gleason score should be considered together in order to more accurately predict the adverse pathologic features of prostate cancer. methods we conducted a cross-sectional study of 105 patients with localized prostate cancer who underwent radical prostatectomy between 2006 and 2013. we recorded gleason scores and psa levels, in addition to the results of patholo...

osteoporosis is a silent epidemy of today's world, and is also a prevalent problem of health in iran. the role of nutrients such as ascorbic acid, a key antioxidant vitamin, in this disease has recently attracted researchers' attention. in this study, we studied the relation between plasma ascorbic acid concentration and bone mineral density (bmd) in women referring to jami clinic, te...

background: tea consumption is common in our country and consumes more than coffee and other drinks. many studies investigated the association between coffee and bone mass density (bmd) but there is few study about association between tea and bmd. according to high prevalence of osteoporosis in country and change in demographic patterns that is associated with increasing middle-aged and older a...

objective: to assess the stability changes as a reflection of early healing around roughened- surface implants in human by resonance frequency analysis (rfa). materials and methods: one hundred and fifty one iti sla implants were placed in either maxilla or mandible of 68 patients. bone type was classified into 4 groups according to lekholm and zarb index. rfa was used for direct implant stabil...

osteoporosis is a skeletal disease characterized by reduction in bone mass and micro architectural changes in the bone, which leads to increased bone fragility. the gold standard for the diagnosis of osteoporosis is the measurement of bone mineral density (bmd) by dual energy x-ray absorptiometry (dxa). periodontal disease is a chronic destructive disease which can occur in adults, young people...

density, viscosity and refractive index of pure, binary and ternary mixtures of diethanolamine (dea) and methyl diethanolamine (mdea) with water have been measured at different temperatures from 288.15 k to 323.15 k at atmospheric pressure. also, this study presents the effects of mixture composition and temperature upon these thermo- physical properties. to measure the density and refractive i...

the intake of antioxidants intake has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of lipophilic antioxidants in prevention of atherosclerosis, we investigated the effects of lycopene on the susceptibility of low-density lipoprotein (ldl) to oxidative modification. in this study, “lycopene” was added to plasma and incubated...
