This paper presents the design and realization of low power, high gain PC based system for ECG and data acquisition of a patient’s heart condition. The advantage of this system is the use of standard CMOS process which will reduce the complexity and cost of the manufacturer. The system consists of three subsystemsOperational Amplifier based Pre-amplifier, ADC and USB interface device. High gain...
The High Luminosity LHC (HL-LHC) will start operating in 2027 after the third Long Shutdown (LS3), and is designed to provide an ultimate instantaneous luminosity of 7:5 × 10 34 cm −2 s −1 , at price extreme pileup up 200 interactions per crossing. number overlapping HL-LHC collisions, their density, resulting intense radiation environment, warrant almost complete upgrade CMS detector. upgraded...
Under the high dynamic conditions, Global Navigation Satellite System (GNSS) signals produce great Doppler frequency shifts, which hinders the fast acquisition of signals. Inertial Navigation System (INS)-aided acquisition can improve the acquisition performance, whereas the accuracy of Doppler shift and code phase estimation are mainly determined by the INS precision. The relation between the ...
Introduction Double Inversion Recovery (DIR) [1] and Flow Sensitive Dephasing (FSD) [2] have been used to suppress arterial signal in vessel wall imaging. However, the “black blood” effect of DIR and FSD depends on blood flow, which makes these techniques less effective with slow or in-plane flow. In this work, T1 and T2 differences between blood and vessel wall were exploited using a T2-prepar...
BACKGROUND Intensive care units (ICUs) are high-risk areas for transmission of antimicrobial-resistant bacteria, but no controlled study has tested the effect of rapid screening and isolation of carriers on transmission in settings with best-standard precautions. We assessed interventions to reduce colonisation and transmission of antimicrobial-resistant bacteria in European ICUs. METHODS We ...
Objectives: Persian is a pro-drop language with canonical Subject-Object-Verb (SOV) word order. This study investigates the acquisition of word order in Persian-speaking children. Methods: In the present study, participants were 60 Persian-speaking children (30 girls and 30 boys) with typically developing language skills, and aged between 30-47 months. The 30-minute language samples were audio...
Background: Observing the enhancing plaques in magnetic resonance imaging (MRI) is one of the most valuable diagnostic modalities in confirming the diagnosis of multiple sclerosis (MS), its recurrence and for better detection of active disease. Since active lesions discovery can improve designating diffusion in time diagnosis of MS and controlling disease activity, and there is not any definite...

First language acquisition requires relatively little effort compared to foreign language acquisition and happens more naturally through informal learning. Informal exposure can also benefit foreign language learning, although evidence for this has been limited to speech perception and production. An important question is whether informal exposure to spoken foreign language also leads to vocabu...
the aim of this study was to compare the performance of analogy (implicit),explicit and discovery learning in the retention and transfer of a topspin shot underpsychological pressure. for this purpose, 36 volunteer high school students wererandomly allocated to three treatment conditions: explicit, analogy, and discoverylearning. after performing 300 trials in the acquisition phase, an immediat...
