Physical density is a numerical measure of the concentration of individuals or physical structures within a given geographical unit. It is an objective, quantitative and neutral spatial indicator. However, in practice, physical density takes on a real meaning only if it is related to a specified scale of reference. For instance, density expressed as ratio of population to land area can vary sig...

background: due to its minimal systematic adverse effects, transdermal estrogen is widely used for the prevention of osteoporosis in postmenopausal women.the present meta-analysis aimed to clarify the effects of transdermal estrogen on bone mineral density (bmd) of postmenopausal women.methods: studies were identified by searching electronic databases including cochrane library, medline, embase...

Density estimation is a fundamental task in statistics and machine learning that aims to estimate, from set of samples, the probability density function distribution generated them. There are different methods for addressing this problem but recently deep-neural have emerged as powerful alternative. This paper presents novel method neural based on matrices adaptive Fourier features. commonly us...

Abstract We show that there exist uncountably many (tall and nontall) pairwise nonisomorphic density-like ideals on $\omega $ which are not generalized density ideals. In addition, they nonpathological. This answers a question posed by Borodulin-Nadzieja et al. in [this Journal , vol. 80 (2015), pp. 1268–1289]. Lastly, we provide sufficient conditions for ideal to be necessarily ideal.

osteoporosis is a major health problem because of the large health care costs associated with its clinical consequences. it is therefore of great importance to identify modifiable risk factors. we investigated association between fruit and vegetables intake and bone mineral density in rural population of tehran surroundings. subjects were a subgroup of a large study on prevalence and causes of ...
