The medial temporal lobe (MTL) is involved in mnemonic processing. The perirhinal cortex (PRC) plays a role in object recognition memory, while the hippocampus is required for certain forms of spatial memory and episodic memory. The lateral entorhinal cortex (LEC) receives direct projections from PRC and is one of the two major cortical inputs to the hippocampus. The transformations that occur ...
مبدل تشدیدی llc یکی از مناسبترین آرایش¬های مداری برای طراحی منابع تغذیه با ولتاژ خروجی ثابت است و به طور گسترده در طراحی منابع تغذیهdc- dc به کار می¬رود. از جمله مزایای مهم این مبدل، به عملکرد آن در حالت کلیدزنی در ولتاژ صفر ، به ازای تغییرات وسیع ولتاژ ورودی و بار می¬توان اشاره نمود که اجازه می¬دهد مبدل در فرکانس زیاد کار کند بدون اینکه بازده آن کاهش یابد. با افزایش فرکانس کلیدزنی و کاهش انداز...
Time variation within an OFDM symbol causes intercarrier interference (ICI). In this letter, frequency-domain partial response coding (PRC) is investigated to reduce ICI in the Alamouti SFBC-OFDM system. Based on the expression of the ICI power in the SFBC-OFDM system with PRC, the near-optimal weights of PRC are derived. Simulation results show that the PRC scheme can reduce ICI effectively. k...
The sensitivity of the circadian pacemaker of the field mouse Mus booduga to diffuse daylight pulses of 15 min duration and 1000 lux intensity was measured in a series of experiments and a phase response curve (PRC) constructed. The PRC evoked was of type-I with significant quantitative differences compared to the PRCs constructed for other light stimuli (fluorescent and incandescent light sour...

We developed and validated a pseudo-range correction (PRC) modeling system that can prevent degradation of positioning accuracy even in situations where one cannot obtain PRC messages for Differential Global Navigation Satellite System (DGNSS). A PRC modeling scheme was devised based on the repeat time of GNSS satellites and previously-collected PRC data. The difference between the modeled and ...
Polycomb repressor complexes (PRCs) are important chromatin modifiers fundamentally implicated in pluripotency and cancer. Polycomb silencing in embryonic stem cells (ESCs) can be accompanied by active chromatin and primed RNA polymerase II (RNAPII), but the relationship between PRCs and RNAPII remains unclear genome-wide. We mapped PRC repression markers and four RNAPII states in ESCs using Ch...
The transcriptional coactivator PGC-1α is a potent regulator of skeletal muscle metabolism. Less is known about the structurally similar PGC-1α-related coactivator (PRC) that is enriched in myoblasts and adult skeletal muscle. The present study was designed to determine the effect of PRC on the metabolic profile of C2C12 myotubes. Overexpression of full-length PRC increased PRC gene expression ...
در این پروژه ابتدا به معرفی و طراحی یک برنامه ریز ممریستور می پیردازیم. سپس، به طراحی سه مدار تقویت کننده عملیاتی کم مصرف، مبدل دیجیتال به آنالوگ موازی و مبدل دیجیتال به آنالوگ سریال می پردازیم. تقویت کننده های عملیاتی و مبدل های دیجیتال به آنالوگ برای تمامی مهندسان برق مدارهایی آشنا و بسیار پر کاربرد هستند. مبدل های دیجیتال به آنالوگ با تبدیل داده های دیجیتالی به خروجی آنالوگی(جریان یا ولتا...
Studies examining the neural correlates of face perception and recognition in humans have revealed multiple brain regions that appear to play a specialized role in face processing. These include an anterior portion of perirhinal cortex (PrC) that appears to be homologous to the face-selective 'anterior face patch' recently reported in non-human primates. Electrical stimulation studies in the ma...
