Commonly, factor analysis is a method for dimension reduction: it reduces the dimension of the original space by representing the full matrix as the product of two much smaller matrices plus random noise. We are able to model the variability among the observed variables by projection from a high dimensional space to a low dimensional one, such from 3D to 2D as shown in Figure 1(a). To do this, ...

in this article, a numerical approximation to the solution of the newell-whitehead equation (nwe) and cauchy problem of ill-posed non-linear diffusion equation have been studied. the presented scheme is obtained by using the derivative of the cubic b-spline quasi-interpolation (bsqi) to approximate the spatial derivative of the dependent variable and first order forward difference to approximat...

It is widely acknowledged that pronunciations in spontaneous speech di er signi cantly from citation form. For this reason, pronunciation modeling has received considerable attention in recent automatic speech recognition literature. Most of the attention however has focussed on describing an alternate pronunciation as a di erent sequence of phonetic units using the same inventory of phones whi...

Spatial variability in crop production occurs as a result of spatial and temporal variations in soil structure and fertility; soil physical, chemical and hydraulic properties; irrigation applications; pests and diseases; and plant genetics. It is argued that this variability can be managed and the efficiency of irrigation water use increased by spatially variable application of irrigation water...

Background: Air pollution has become an important factor restricting China's economic development and has subsequently brought a series of social problems, including the impact of air pollution on the health of residents, which is a topical issue in China. Methods: Taking into account this spatial imbalance, the paper is based on the spatial panel data model PM2.5. Respiratory disease mortality...

the aim of the present study was to evaluate the effect of melatonin as an antioxidant on spatial navigation memory in male diabetic rats. thirty-two male white wistar rats weighing 200 ± 20 g were divided into four groups, randomly: control, melatonin, diabetic and melatonin-treated diabetic. experimental diabetes was induced by intraperitoneal injection of 50 mg kg-1 streptozotocin. melatonin...
