1. The aggregation model of coexistence states that intraspecific aggregation over patches stabilizes species coexistence and allows high diversity in patchy systems.The model is reviewed, with emphasis on the methods of analysis of aggregation data. Essential improvements in existing methods of analysis are presented. 2. The density, rather than the number, of competitors is important when pat...

Traditional studies of familial aggregation are aimed at defining the genetic (and non-genetic) causes of a disease from physiological or clinical traits. However, there has been little attempt to use genome-wide gene expressions, the direct phenotypic measures of genes, as the traits to investigate several extended issues regarding the distributions of familially aggregated genes on chromosome...

When tobacco is smoked, chewed or snuffed, nicotine is absorbed by the lungs or mucous membrane and quickly moved into the bloodstream, where it is circulated throughout the brain. In fact nicotine is highly dangerous to be consumed in any form. The present study was conducted to know the adverse effects of nicotine on the platelet aggregation in cerebral microvessels of mice. Male mice of aver...

To study the resistance to standard dosage of clopidogrel among Iranian patients following percutaneous coronary intervention measured by platelet aggregation test.Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. Patients received standard dosage...

In Wireless Sensor Networks (WSNs) due to unfavorable environmental conditions that sensor nodes are placed into and some other reasons, power limitation of sensor nodes is the main challenge. Emerging in-network aggregation techniques are increasingly being sought to overcome this limitation and to save energy. Data aggregation methods can be facilitated by cluster based communication model. O...

Often it is appropriate to have more than one decision maker perform the pairwise comparisons that are part of the Analytic Hierarchy Process (AHP). With group judgments one would hope for broad consensus among the decision makers, in which case one would aggregate judgments via their geometric mean. However, consensus may not always be reached and significant dispersion may exist among the jud...
