Objective: This study aimed to investigate the effect of working memory (WM) training on WM capacity and performance of novice karate practitioners (karateka). Methods: Research method is quasi-experimental with a pretest posttest control group design. A total of 24 karate practitioners were selected among Alborz (Alborz Province, iran) novice karateka by convenience sampling me...

Estrogen has a widespread and complex influence on brain capabilities such as learning and memory. On the other hand, hippocampus as one of the main brain structures has an important role in spatial information processing. There is some evidence on the existence of estrogen receptors in the hippocampal CA1 area. So, in this study the effect of intrahippocampal injection of estradiol benzoate on...

An efficient Lookup Table (LUT) design for memory-based multiplier is proposed.  This multiplier can be preferred in DSP computation where one of the inputs, which is filter coefficient to the multiplier, is fixed. In this design, all possible product terms of input multiplicand with the fixed coefficient are stored directly in memory. In contrast to an earlier proposition Odd Multiple Storage ...

Emerging non-volatile memories based on resistive switching mechanisms attract intense R&D efforts from both academia and industry. Oxide-based Resistive Random Acces Memories (OxRAM) gather noteworthy performances, such as fast write/read speed, low power and high endurance outperforming therefore conventional Flash memories. To fully explore new design concepts such as distributed memory in l...

One of the most important items for better file system performance is efficient buffering of disk blocks in main memory. Efficient buffering helps to reduce the widespeed gap between main memory and hard disks. In this buffering system, the block replacement policy is one of the most important design decisions that determines which disk block should be replaced when the buffer is full. To o...

Objective(s): Calcineurin (CN) is a main phosphatase and a critical regulator of cellular pathways for learning, memory, and plasticity. The FK-506 (tacrolimus),a phosphatase inhibitor, is a fungal-derived agent and a common immune suppressant extensively used for tissue transplantation. To further clarify the role of CN in different stages oflearning and memory the main aim of this study was t...

Objective: The present study aimed to compare prospective and retrospective memory impairment and attention deficit in people suffering from chronic low back pain with those cognitive functions in healthy subjects. Furthermore, this study examines the relation between severity and duration of pain and prospective and retrospective memory impairment and attention deficit. Me...
