In this paper, we propose a method in order to compensate contortion of page image which is caused by photographing a book opened and placed face-up (two pages opposite each other state) on the stage just above. For compensating contortion 3-D shape information of page surface is necessary to apply some geometrical adjustment. To obtain much higher resolution image a page needs to be photograph...

This paper is aimed at introducing a new approach to estimate the density of Brown Plant Hoppers (BPHs) at provincial scale. The model is based on the topology of a light-traps network (to gather the information about the BPHs) of a province. The BPHs density is determined based on Unit Disk Graph technique where each light-trap becomes a vertex and the edges reflect the relations on the mutual...

A theorem of Lovv asz asserts that (H)== (H) r=2 for every r-partite hy-pergraph H (where and denote the covering number and fractional covering number respectively). Here it is shown that the same upper bound is valid for a more general class of hypergraphs: those which admit a partition (V 1 ; : : : ; V k) of the vertex set and a partition p 1 + +p k of r such that je\V i j p i r=2 for every ...

—Two subspecies of the big brown bat (Eptesicus fuscus) are reported to occur in Nebraska. The eastern race, E. f. fuscus, is reportedly bigger and darker than its western counterpart E. f. pallidus. Where these 2 subspecies come in contact is the subject of debate. We used external, cranial, and colorimetric data to investigate geographic variation among populations of E. fuscus in Nebraska to...

Sheep have many advantages to study neurogenesis in comparison to the well-known rodent models. Their development and life expectancy are relatively long and they possess a gyrencephalic brain. Sheep are also seasonal breeders, a characteristic that allows studying the involvement of hypothalamic neurogenesis in the control of seasonal reproduction. Sheep are also able to individually recognize...

Variability of gene expression of cortical precursors may partially reflect the operation of the gene regulatory network and determines the boundaries of the state space within which self-organization of the cortex can unfold. In primates, including humans, the outer subventricular zone, a primate-specific germinal zone, generates a large contingent of the projection neurons participating in th...
