Objective: To investigate the correlation between cerebral small vessel disease (CSVD) burden and motor performance of lower and upper extremities in community-dwelling populations. Methods: We performed a cross-sectional analysis on 770 participants enrolled in the Shunyi study, which is a population-based cohort study. CSVD burden, including white matter hyperintensities (WMH), lacunes, cereb...

Using fast tapping tasks with each of the four fingers (single-finger tapping) and with two of the fingers used alternately (double-finger tapping), the ability to make rapid tapping movement by the individual fingers was compared between expert pianists and nonmusician controls in both genders. Maximal pinch and grasp forces were also measured to assess strength of individual fingers and whole...

Without practice, bimanual movements can typically be performed either in phase or in antiphase. Complex temporal coordination, e.g., during movements at different frequencies with a noninteger ratio (polyrhythms), requires training. Here, we investigate the organization of the neural control systems for in-phase, antiphase, and polyrhythmic coordination using functional magnetic resonance imag...

Providing transparent replication of servers has been a major goal in the fault tolerance community. Transparent replication is particularly challenging for highly nondeterministic applications, such as the ones that use multithreading. For such applications, keeping replicas in a consistent state becomes non-trivial. One way to deal with the non-determinism is to use a leader/follower approach...

aim: investigating factors affecting the adoption of preventive behaviors in women with osteoporosis is necessary. this study aims at determining the preventive treatment of osteoporosis in women in fasa using the health belief model (hbm) during 2014. method: in this cross-sectional study, 401 women (aged 30-50 years) covered by the health centers in fasa city were randomly chosen. construct o...

It is unclear whether the cortical representation of swallowing is lateralized to the left cerebral hemisphere, right hemisphere, or bilaterally represented. As dysphagia is common in acute stroke, it is important to elucidate swallowing lateralization to facilitate earlier detection of stroke patients who may be at greater risk for dysphagia and aspiration. In this study, a modified dual task ...

Rhythms, or patterns in time, play a vital role in both speech and music. Proficiency in a number of rhythm skills has been linked to language ability, suggesting that certain rhythmic processes in music and language rely on overlapping resources. However, a lack of understanding about how rhythm skills relate to each other has impeded progress in understanding how language relies on rhythm pro...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...
