utes to their tendency to form clumps spontaneously. Since the rise of the field of sociobiology, the study of Though the exact relationship between these behaviors the biological basis of social behavior, scientists have is not known, they all appear to be related to food restriven to assign genetic origins for a variety of social sponse in some manner: in the absence of food, clumpbehaviors. ...

A new segmentation method for medical image with intensity clustering is enclosed. In the intended approach, an improved K-means and EM algorithm are combined to develop a hybrid strategy better clumping. The advent aims exploit ability of providing well distributed clump closeness clumps provided by EM. introductory algorithm. This clumping process outcomes in canters which given data. These f...

A 79-year old man presented with chest pain and fatigue. He was found to have anemia (hemoglobin 8.8 g/dL) and leukocytosis (white blood cell count 244x10/L) with a predominance of lymphocytes (94%). Flow cytometric study and flourescence in situ hybridization analysis of the peripheral blood lymphocytes were consistent with a diagnosis of mantle cell lymphoma. A peripheral smear obtained from ...

I T IS WELL DOCUMENTED that platelet-thrombi are found during some inflammatory processes, but the exact mechanisms involved are still unknown. The authors demonstrated’3 the appearance of platelet-clumping substance in heparinized rabbit plasma and a concomitant decrease in the circulating platelet count after the intravenous injection of high molecular weight substances such as bacterial endo...

We have earlier shown that clumping factor A (ClfA), a fibrinogen binding surface protein of Staphylococcus aureus, is an important virulence factor in septic arthritis. When two amino acids in the ClfA molecule, P(336) and Y(338), were changed to serine and alanine, respectively, the fibrinogen binding property was lost. ClfAP(336)Y(338) mutants have been constructed in two virulent S. aureus ...

Hot, massive (OB) stars experience strong line-driven stellar winds and mass loss. As the majority of efficient driving lines are metallic, amount wind loss is dependent on metallicity Z. In addition, intrinsically inhomogeneous clumpy. However, to date, neither theoretical nor empirical studies have investigated how such clumping may also depend We theoretically degree due line-deshadowing ins...

OBJECTIVES The study was undertaken to investigate vancomycin-resistant (vanA) Enterococcus faecalis isolates carrying aggregation substance (AS) gene(s) for their ability to co-transfer vanA and AS genes. METHODS Six vanA clumping-positive E. faecalis isolates (five human and one food sample) carrying one or more AS genes (prgB, asa1, asa373) were analysed for co-transfer of vanA and AS gene...

Animals show impulsiveness when they prefer a smaller more immediate option, even though a larger more delayed option produces a higher intake rate. This impulsive behavior has implications for several behavioral problems including social cooperation. This paper presents two experiments using captive blue jays (Cyanocitta cristata) that consider the effects of payoff accumulation and temporal c...
