Mass rearing of anopheles stephensi on human blood by artificial feeding under laboratory conditions
Introduction: In order to control the diseases that are transmitted to human and animal by arthropod vectors, it is necessary to investigate vectors and to recognize control methods as well. These studies are applicable by rearing the colonies of arthropod blood-feeders like malaria and leishmaniasis in laboratory. The purpose of this study was to produce mass production of Anopheles stephens...

We consider the Wright-Fisher model with exponential population growth and investigate effects of population growth on the shape of genealogy and the distributions of several test statistics of neutrality. In the limiting case as the population grows rapidly, the rapid-growth-limit genealogy is characterized. We obtained approximate expressions for expectations and variances of test statistics ...
In this paper we present a method for drawing inferences about the process of financial losses that are associated with the operations of a business. For example, for a bank such losses may be related to erroneous transactions, human error, fraud, lawsuits, or power outages. Information about the frequency and magnitude of losses is obtained through the search of a number of sources, such as pr...
