Objective. To estimate if there is a relationship between the results of tests of neurocognition and performance on a laparoscopic surgery simulator. Methods and Materials. Twenty participants with no prior laparoscopic experience had baseline cognitive tests administered (Trail Making Test, Part A and B (TMT-A and TMT-B), Grooved Peg Board Test, Symbol Digit Modalities Test, Symbol Digit Recal...

objectives: the purpose of this research was to explore the possible differences in the working memory of monolingual (persian) and bilingual  (persian-baluchi) children. we wanted to examine if there is a statistically significant relationship between working memory and bilingualism. methods: four working memory (wm) tests, assessing three wm components, were administered to 140 second grade s...

The design of a fast divider is an important issue in high-speed computing. The paper presents a fast radix-4 SRT division architecture. Instead of ®nding the correct quotient digit, an estimated quotient digit is ®rst speculated. The speculated quotient digit is used to simultaneously compute the two possible partial remainders for the next step while the quotient digit is being corrected. Thu...

Digit recognition for license plate recognition is a core process, simplicity on the algorithm to recognize digits on the LPR context is of importance, given that there is an ever increasing vehicle flow and need for recognizing license plates on different environments and applications such as: unattended parking lots, automatic toll collection, traffic supervision, access control of restricted...

This paper proposes the implementation of digit-serial Canonical Signed-Digit (CSD) coefficient FIR filters which can be used as format conversion filters in place of the ones employed for the MPEG2 TM5 (test model 5). A canonical digit representation of signed numbers is used to reduce the complexities in multiply operations. Practical design guidelines of digit-serial CSD FIR filter are provi...

Dichotic listening to verbal stimuli results in a right ear advantage (REA), indicating a left hemisphere processing superiority. The magnitude of the REA can be modulated by instructions to direct attention to the left or right ear stimulus. A previous study from our laboratory showed that presenting a prime syllable before the presentation of the dichotic syllables increases reports of the no...

Dichotic word recognition was evaluated in free-recall, directed-attention right, and directed-attention left response conditions. All participants were right-handed and included a group of young adults with normal hearing and two groups of older adults with sensorineural hearing loss. Dichotic word recognition performance was best for young adults and decreased for each older group. A right-ea...

Objective: The aim of this study was to investigate whether people exposed to the Chinese Famine in fetal period or in multiple stages of childhood are associated with cognitive decline in adulthood. Furthermore, the nutritional environment of adulthood was explored as an important factor in this correlation. Methods: 1162 adults born between 1952 and 1964 were recruited. They were divided into...
