A classical bidirectional associative memory (BAM) suffers from low storage capacity and abundance of spurious memories though it has the properties of good generalization and noise immunity. In this paper, Hamming distance in recall procedure of usual asymmetrical BAM is replaced with modified Hamming distance by introducing weighting matrix into connection matrix. This generalization is valid...

The (31)P-nuclear magnetic resonance chemical shift of phosphatidic acid in a membrane is sensitive to the lipid head group packing and can report qualitatively on membrane lateral compression near the aqueous interface. We have used high-resolution (31)P-nuclear magnetic resonance to evaluate the lateral compression on each side of asymmetrical lipid vesicles. When monooleoylphosphatidylcholin...

Topological relationships are the most important spatial relationships in geographical information science (GIS). There are many models of spatial relationships; the most popular model of them is 9-intersection model (9IM). There are two main problems in 9intersection model: topological paradox and linear dependency. We solve the problem of topological paradox by using the lower dimensional par...

The unequal division model proposed for budding yeast (L. H. Hartwell and M. W. Unger, J. Cell Biol. 75:422-435, 1977) was tested by bud scar analyses of steady-state exponential batch cultures of Saccharomyces cerevisiae growing at 30 degrees C at 19 different rates, which were obtained by altering the carbon source. The analyses involved counting the number of bud scars, determining the prese...

OBJECTIVE To determine whether clinical presentations and risk factor profiles differ between periventricular venous infarction (PVI) and arterial presumed perinatal ischemic stroke (APPIS). DESIGN Retrospective cohort study. PARTICIPANTS A total of 59 children with presumed perinatal ischemic stroke (PPIS) from the SickKids Children's Stroke Program who were carried to term (63% boys). S...
