— We study analytic properties of height zeta functions of equivariant compactifications of the Heisenberg group.

We prove Manin’s conjecture for bi-equivariant compactifications of unipotent groups.

We investigate analytic properties of height zeta functions of toric bundles over ag varieties.

Height restricted resolution (proofs or refutations) is a natural restriction of resolution where the height of the corresponding proof tree is bounded. Height restricted resolution does not distinguish between treeand sequence-like proofs. We show that polylogarithmic-height resolution is strongly connected to the bounded arithmetic theory S 2(α). We separate polylogarithmic-height resolution ...

Estimating urban trees growth, especially tree height is very important in urban landscape management. The aim of the study was to predict of tree height base on tree diameter. To achieve this goal, 921 trees from five species were measured in five areas of Mashhad city in 2014. The evaluated trees were ash tree (Fraxinus species), plane tree (Platanus hybrida), white mulberry (Morus alba), ail...

introduction: central nervous system develops during the first years of life. millions of synapses form among nervous cells before two years of age. the present research was performed to assess the effects of mothers’ training about complementary feeding and developmental skills on growth and development of 5-7 month infants referring to health centers in city of shiraz in southwest of iran. me...
