Health inequality exists in this world, across, within, and between every society and in every State. These inequalities manifest themselves in a number of ways, including but not limited to malnutrition levels, chronic diseases such as diabetes, access to fresh foods, rates of incarceration, and exposure to environmental hazards. There is an association between a lower Socio-Economic Status (S...

background: this study aimed to evaluate the perception of lay people regarding determinants of health at global level and factors affecting it. methods: data was collected from international social survey program (issp) and world bank website. multilevel regression analysis was done and lay people’s perception regarding health behavior, environment, poverty and genes as health determinants was...

we study the set of all determinants of adjacency matrices of graphs with a given number of vertices. using brendan mckay's data base of small graphs, determinants of graphs with at most $9$ vertices are computed so that the number of non-isomorphic graphs with given vertices whose determinants are all equal to a number is exhibited in a table. using an idea of m. newman, it is proved that if $...

A present challenge in complex systems is to identify mesoscale structures that have distinct dynamical implications. In this paper we present a detailed investigation of a previously observed dynamical equivalence of certian ecological food webs. We show that this equivalence is rooted in mesoscale symmetries that exist in these webs. Certain eigenvectors of the Jacobian describing dynamical m...

We prove an extension of Yuan’s Lemma to more than two matrices, as long as the set of matrices has rank at most 2. This is used to generalize the main result of [A. Baccari and A. Trad. On the classical necessary second-order optimality conditions in the presence of equality and inequality constraints. SIAM J. Opt., 15(2):394–408, 2005], where the classical necessary second-order optimality co...

We study Pesenti–Szpiro inequality in the case of elliptic curves over Fq(t) which occur as subvarieties of Jacobian varieties of Drinfeld modular curves. In general, we obtain an upperbound on the degrees of minimal discriminants of such elliptic curves in terms of the degrees of their conductors and q. In the special case when the level is prime, we bound the degrees of discriminants only in ...

abstract previous research have shown that physical and mental illness and mortality are influenced by class status, material life standards, genetics and infection, but today social context attracted attention. in this paper social capital as a composition of social trust, support and relations seen as a mental health determinant. the aim of this paper is examining the relationship between soc...
