In this paper, we propose the design of low power level-converting retention flip-flop (RFF)using LSSR technique for Zigbee System-onchips (SoCs).The proposed retention flip-flop allows the voltage regulator which generates the core supply voltage (VDD, core) is turned off during the standby mode and thus reduces the standby power and dc current of the Zigbee SoCs. This method is the combinatio...

background and objectives: the prevalence of diabetes mellitus (insulin resistance) in individuals with down's syndrome is more than healthy people, which is possibly because of the high prevalence of obesity among them. adiponectin is one of adipose tissue-secreted adipocytokines, which plays a role in pathogenesis of obesity and insulin resistance. this study was carried out with the aim of d...

the photoanthropometric method was used to study the facial features in 136 iranian children with down syndrome, aged 4 to 14 years. nineteen parameters were investigated and compared to an age related control group of 100 normal iranian children. the obtained measurements were related to reference values in the same faces. the normal range was defined by age related index values between the 20...

objectives: down syndrome is the most common chrosomal disorder in which the fine and gross motor skills due to lack of proper sensory experience are disturbed. the role of dexterity in activity of daily living, interaction with environment and independency is quiet crucial in down syndrome. therefore, the aim of this study was to investigate the effects of simultaneous application of superfici...
