<b>Background:</b> Pulsed field ablation (PFA) is a new type of physical energy source in the fields tumor and atrial fibrillation ablation, based on irreversible electroporation with non-thermal, clear boundaries, selective killing, rapid advantages. PFA induces changes electrical conductivity zone, which can be described by step function used to predict zone. However, current rese...

the main purpose of this study was to analyze the causes, impacts and mechanisms of drought crisis management in rural and nomadic communities in iran. 201 experts and managers involved in drought crisis management were surveyed through a complete enumeration/census. face validity and content validity of the questionnaire were confirmed by experts. the calculated cronbach’s alpha for the differ...

the aim of this study was to assess the environmental impact of socio-cultural practices on the water quality of river ganga at the foothills of the garhwal himalayas in uttarakhand state, india. the physico-chemical parameters that contributed to the temporal variation and pollution in the river were identified in this study. principal component analysis (pca) and cluster analysis (ca) were us...

Two experiments evaluated the ability of maternal fatty acid supplementation to alter conceptus and endometrial fatty acid composition. In Exp. 1, treatments were 1) the control, a corn-soybean meal diet; 2) flax, the control diet plus ground flax (3.75% of diet); and 3) protected fatty acids (PFA), the control plus a protected fish oil source rich in n-3 PUFA (Gromega, JBS United Inc., Sherida...

Normal mixture models are often used to cluster continuous data. However, conventional approaches for fitting these models will have problems in producing nonsingular estimates of the componentcovariance matrices when the dimension of the observations is large relative to the number of observations. In this case, methods such as principal components analysis (PCA) and the mixture of factor anal...
