The incidence and mortality rates of testis and prostate cancers in 42 countries were correlated with the dietary practices in these countries using the cancer rates (1988-92) provided by the International Agency for Research on Cancer (IARC) and the food supply data (1961-90) provided by the Food and Agriculture Organization (FAO). Among the food items we examined, cheese was most closely corr...
Gene expression studies produce data with which inferences can be made for thousands of genes simultaneously, allowing researchers to answer questions such as “Which genes are significantly differently expressed between two (or more) conditions?” or “Which genes have a significant association with an outcome or covariate?”. In order to make statements about the statistical significance of thous...
This study aimed to investigate the level of verbal abuse and emotional labor and clinical practice stress of nursing students during clinical practice and determine the effects of the exposure to verbal abuse on emotional labor and clinical practice stress. 212 nursing students, who were juniors and seniors performing clinical practice in Seoul, participated in this study and the data were col...
In this work, we propose a new optimization algorithm for the development of multiparameter crossover equations of state (MC EOS), which incorporates the asymptotic scaling laws near the critical point. This algorithm is based on stepwise regression, which reduces the intercorrelations among the functional terms in the equation and enables the incorporation of the universal crossover formulatio...
Incorporating results from a previously developed finite element model, an uncertainty and parameter sensitivity analysis was conducted using preliminary site-specific data from Horonobe, Japan (data available from five boreholes as of 2003). Latin Hypercube Sampling was used to draw random parameter values from the site-specific measured, or approximated, physicochemical uncertainty distributi...
It is first pointed out that most often used reliability coefficient α and one-factor model based reliability ρ are seriously biased when unique factors are covariated. In the case, the α is no longer a lower bound of the true reliability. Use of Bollen’s formula (Bollen 1980) on reliability is highly recommended. A web-based program termed “STERA” is developed which can make stepwise reliabili...
Accurate estimation of aboveground biomass and carbon stock has gained importance in the context of the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. In order to develop improved forest stratum–specific aboveground biomass and carbon estimation models for humid rainforest in northeast Madagascar, this study analyzed texture measures derived from WorldVie...
A non-invasive blood glucose measurement sensor and the data process algorithm based on the metabolic energy conservation (MEC) method are presented in this paper. The physiological parameters of human fingertip can be measured by various sensing modalities, and blood glucose value can be evaluated with the physiological parameters by the multiple linear regression analysis. Five methods such a...
To develop saffron planting in Urmia, West Azerbaijan, Iran, a split-split plot experiment based on CRBD was carried out in the Urmia University's research farm for two years (2013-14). Nanofertilizers (Fe, P, K and nofertilizer (control)) as main plots, saffron ecotypes (Mashhad, Torbat-Heydarieh, Torbat-jam, Gonabad, Ghaen and Birjand) as subplots and maternal corm weight (6, 8, 10 and 12 g) ...
