introduction: the purpose of this study was to determine na-ca exchanger 2, 3 (ncx2, 3) protein level changes during 2, 5, 10, 15 days after induction of normobaric hyperoxia (ho) preconditioning. materials and methods: rats were divided in two experimental groups. the first group was exposed to 95% inspired ho for 4 h/day for 6 consecutive days (ho). the second group acted as control, and was ...

islam is regarded to pay attention to the characteristics of urban life which can be practiced on the urban settings. not surprisingly, islam has made a great focus on the form and design of cities and prescribed detailed and elaborate regulations for individual and communal life. seen from other way round, the penetration of islam into various regions such as iran, europe, and africa had an un...

Each time a learner in a self-paced online course is trying to answer an assessment question, it takes some time to submit the answer, and if multiple attempts are allowed and the first answer was incorrect, it takes some time to submit the second attempt, and so on. Here we study the distribution of such “response times”. We find that the log-normal statistical model for such times, previously...

An approach to Keystroke Continuous Authentication (KCA) is described founded on a time series analysis based approach that, unlike previous work on KCA (using feature vector representations) takes the sequencing of keystrokes into consideration. The significance of KCA is in the context of online assessments and examinations used in eLearning environments and MOOCs, which are becoming increasi...

This paper develops a model of a learning market-maker by extending the GlostenMilgrom model of dealer markets. The market-maker tracks the changing true value of a stock in settings with informed traders (with noisy signals) and liquidity traders, and sets bid and ask prices based on its estimate of the true value. We empirically evaluate the performance of the market-maker in markets with dif...

Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.
