OBJECTIVES To elucidate the visual significance of the foveal pit by measuring foveal architecture and function and to reassess use of the term foveal hypoplasia (as visual acuity can vary among patients who lack a pit). METHODS We describe 4 patients who lack a foveal pit. Visual acuities ranged from 20/20 to 20/50. Stratus and Cirrus (Carl Zeiss Meditec, Dublin, California) optical coherenc...

Overexpression of the proinflammatory cytokine macrophage migration inhibitory factor (MIF) is linked to a number of autoimmune diseases and cancer. MIF production has been correlated to the number of CATT repeats in a microsatellite region upstream of the MIF gene. We have characterized the interaction of pituitary-specific positive transcription factor 1 (Pit-1) with a portion of the MIF prom...

Plant water transport occurs through interconnected xylem conduits that are separated by partially digested regions in the cell wall known as pit membranes. These structures have a dual function. Their porous construction facilitates water movement between conduits while limiting the spread of air that may enter the conduits and render them dysfunctional during a drought. Pit membranes have bee...

We solve an interesting optimization problem motivated by tolerancing metrology, paper position sensing, and facility location: What rectangle fits best a given set of points? This problem has relations to the minimum width annulus problem and also to the largest empty rectangle problem for both of which O(n log n) time solutions are not known. Nevertheless, for our problem there is a linear ti...

We characterized pit and mound (PM) topography resulting from catastrophic wind in the Coweeta Basin, and located 48 PMs a across a variety of forest types. Our measurements included pit length, width, and depth; and mound height, thickness, and width. Species of fallen trees were identified, and DBH (diameter at breast height, 1.37 m) was measured for biomass determination. We identified five ...

The Largest Empty Circle problem seeks the largest circle centered within the convex hull of a set P of n points in R2 and devoid of points from P . In this paper, we introduce a query version of this well-studied problem. In our query version, we are required to preprocess P so that when given a query line Q, we can quickly compute the largest empty circle centered at some point on Q and withi...

Aquatic field studies were conducted in Tha Mai District, Chanthaburi Province, Thailand. Larval habitats of Anopheles dirus were examined from November 1986 through June 1988 in 42 manmade gem pits. Larvae were found in pits containing clear water under full or partial shade. The abundance of different kinds of mosquito larvae were related to seasonal changes in these aquatic habitats. Variati...

The article represents the materials of study site Beryozogrivsko-Alexeevskoe III that is situated in Low Kama region. earliest findings from this are associated with Kamskaya Neolithic culture. A somewhat later chronological position occupied by complexes represented pit-comb, Russko-Azibeyskaya and Novoil’inskaya ceramics. complex Garinskaya Eneolithic culture deserves special attention artic...
