This paper presents a segmentation algorithm for gray-level images and addresses issues related to its performance on noisy images. It formulates an image segmentation problem as a partition of an image into (arbitrarily-shaped) connected regions to minimize the sum of graylevel variations over all partitioned regions, under the constraints that (1) each partitioned region has at least a specif...

We present a sound, complete and relatively straightforward tableau method for deciding valid formulas in the propositional version of computation tree logic CTL*. This is the first such tableau. CTL* is an exceptionally important temporal logic with applications from hardware design to agent reasoning but there is no easy automated reasoning approach to CTL*. The tableau here is a traditional ...

results in the first three years, the team managed the care of 812 admissions. mean age wasn 44.3 years (sd = 24.8) and mean length of hospital stay was 6.1 days (sd = 10.9). ofn these individuals, 674 attended for 6 month follow-up with 52.2% having a good outcomen on extended glasgow outcome score. patients and their relatives' feedbacks weren excellent with an average score of 4.7/5 on overa...

In order to understand the key metabolic pathways and key genes involved in the latex biosynthesis process in rubber tree, we studied the differential gene expression between latex and leaves of rubber tree by cDNA microarray. The significant analysis of microarray (SAM) method was used, and genes that were differentially expressed in the latex and leaves of rubber tree were selected and subjec...

The fossil record is the only source of information on the long-term dynamics of species assemblages. Here we assess the degree of ecological stability of the epifaunal pterioid bivalve assemblage (EPBA), which is part of the Middle Devonian Hamilton fauna of New York--the type example of the pattern of coordinated stasis, in which long intervals of faunal persistence are terminated by turnover...

Laparoscopic Adjustable Gastric Banding (LAGB) was done for the first time in Belgium in 1993. Gastric torsion after band slippage is extremely rare. Literature review of gastric banding and complications in pregnancy did not reveal any case of gastric torsion. Hence, we report this rare case of gastric torsion in a pregnant lady following gastric banding.
