Arti cial evolution can automatically derive the con g uration of a recon gurable hardware system such that it performs a given task Individuals of the evolving popu lation are evaluated when instantiated as real circuits so if constraints inherent to human design but not to evolu tion are dropped then the natural physical dynamics of the hardware can be exploited in new ways The notion of an a...

The uptake of 3H-pyridoxol by everted intestinal rings of the rat was studied mainly at concentrations of 0.1-4ƒÊM of the vitamin in the medium. Incubation of the tissue at 37•Ž for 60 min in Krebs-Ringer bicarbonate medium containing glucose and labelled pyridoxol resulted in intracellular accumulation of the labelled compounds. The total intracellular concentration of the compounds after the ...

A 15 min method for the isolation of clean liver cell nuclei from normal, starved, hepatectomized and sham operated mice in mediums not containing bivalent cations is described. The iso­ lation medium contained 0.5 m M spermidine for stabilization of the nuclear membrane, and macaloid and EDTA for inhibition of RNase activity. The RNA/DNA ratio in normal liver cell nuclei was 0.25 — 0.29 and th...

A fibril lation (AF) is characterized by irregular, disorganized and chaotic electrical activity of the atrium. It is a common arrhythmia and major cause of morbidity and mortality not only in the western world but in India as well. Rheumatic valvular heart disease (RVHD) continues to remain the most frequent cause of AF in a recent survey in public and private institutes in India (Fig. 1, unpu...

We demonstrate the technological value of non-monotonic logics by an example: We use prioritized defaults for candidate generation in diagnosis from first principles. We implement this non-monotonic logic by TMS similar to default logic. Prioritized defaults allow an easy formu­ lation of a diagnosis problem including state­ ments such as 'eletrical parts are more reliable than mechanical ones'...

For the usual st raight·line model, in whic h the independent variable ta kes on a fixed, kno wn se t of va lues, it is shown that the sample corre lation coeffi cie nt is distributed as Q with (n-2) degrees of freedom and noncentralit y O=({3 /CT) V~(Xi X)2. The Q variate has been defin ed and studied e lse· where by Hogben et al. It is noted that the square of the correlation coeffi cient is ...

The aim of the study was to determine the corre-lation between risk factors and diabetic retino-pathy, which is the leading cause of blindness indeveloped countries for patients aged 20 to 65.We compared risk factors between patients wi-thout retinopathy, with non-proliferate and withproliferate retinopathy (p< 0.05). Duration ofdiabetes is most important for the dev...

The eucalypts as a group are attractive because of their rapid growth. This results in very high yields on a volume basis and in combination with the comparatively high specific gravities, the yields of dry fiber can be truly impressive. Maximum yield of dry fiber is the logical goal when the anticipated use is for fuel, or as a chemical feedstock for processes such as destructive distil­ latio...

the production of colony-stimulating factors (csf) is delicately controlled through a complex network of humoral and environmental factors. we have studied some of the mechanisms which regulate the production of csf as compared to general protein synthesis in the lung tissue ill vitro. when lung tissue from mice was cultured for various times in serum free medium, the first detectable level of ...

Financial derivatives commonly contain pre-mature termination clauses, which are embedded rights held by the holder or writer. Well known examples of these stopping rights include the early exercise right in American options, the callable right in callable securities and the prepayment right in mortgage loans. In this paper, we show how to model the mortgagor’s prepayment in mortgage loans and ...
