The firing of place cells in the rodent hippocampus is reliable enough to infer the rodent's position to a high accuracy; however, hippocampal firing also reflects the stages of complex tasks. Theories have suggested that these task-stage responses may reflect changes in reference frame related to task-related subgoals. If the hippocampus represents an environment in multiple ways depending on ...

This study attempted to investigate the impact of teacher’s code-switching on the acquisition of a problematic grammatical structure, namely, object relative clauses, by intermediate EFL learners. Moreover, a secondary objective of the study was to determine the EFL learners’ attitudes and opinions regarding the effectiveness of teacher’s code-switching in their learning of a specific aspect of...

Methods A retrospective observational study was conducted on SJIA patients treated in a French pediatric rheumatology reference center using the CEMARA register, a nationwide information system for rare diseases. We included patients who started biotherapy between 2005 and 2012 with a follow-up of at least 6 months after treatment initiation. Factors for switching or discontinuation of a biolog...

Design techniques for robust, low-power CMOS circuits are presented for applications in wireless cubicmillimeter sensor nodes. First, the design of a two-transistor voltage reference is described and its characteristics simulated. Then, a low-voltage toggle flip-flop circuit is discussed and modeled using standard switching theory. Finally, a study of the battery used to power the cubic-millime...

This paper discusses fuzzy sliding mode controller applied for induction motor field oriented control with space-vector pulse-width modulated inverter. The speed control is obtained by controlling the inverter switching frequency determined by the reference voltage resulted by the controller. Simulation results show that fuzzy sliding mode controller performed satisfactorily and better compared...

This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...

A spin-torque switchable magnetic tunnel junction contains two ferromagnetic electrodes across a barrier that supports spin-polarized current. The induced switching of its more agile, or “free” layer provides the “write” mechanism. Often dynamics non-switching “reference” is also important. Here, we illustrate such involving both free and reference layers by using an exchange-coupled two-macros...

The DRAM is a typical bottleneck of a digital system. Moreover, the architectures are getting more complex, which makes their evaluation harder. In this paper, we propose a fast and early estimation of the memory system performance with an actual application in mind. A DRAM simulator, Rascas, developed for this purpose is presented. Rascas is used to study the DRAM behavior with several memory ...
