absence of one in the prokaryotes; Eukaryotes also have distinct membrane-bound organelles‚ while prokaryotes do not (Stanier et al.‚ 1970a; Mauseth‚ 2009). It is after discovery and examination of these organelles that first led to the Endosymbiont Hypothesis or Endosymbiont Theory‚ as it is sometimes called (both terms are used throughout). In this essay we shall look at the history of the theory‚ how it was formed‚ who the most influential collaborators were‚ and how it is applied to the evolution

Access log sampler Step-by-step This is a short tutorial on Jmeter’s access log sampler. The purpose of the access log sampler is to provide an easy way to simulate production traffic. There are several benefits to using access logs. 1. rather than guess what users are doing‚ the test plan is using real traffic data 2. as the traffic pattern changes‚ the access log provides a record of individual changes and general shifts in usage 3. access logs contain a lot of useful data‚ which may provide

Stock Market Prices Do Not Follow Random Walks: Evidence from a Simple Specification Test Andrew W. Lo A. Craig MacKinlay University of Pennsylvania In this article we test the random walk hypothesis for weekly stock market returns by comparing variance estimators derived from data sampled at different frequencies. The random walk model is strongly rejected for the entire sample period (19621985) and for all subperiod for a variety of aggregate returns indexes and size-sorted portofolios. Although

The dopamine hypothesis of schizophrenia states that psychosis occurs when there is too much dopamine in the brain. This occurs through its role in the mesocortical system. There is much evidence to support this theory. For example‚ as mentioned previously‚ illegal drug
