The regeneration of digit tips in mammals, including humans and rodents, represents a model for organ regeneration in higher vertebrates. We had previously characterized digit tip regeneration during fetal and neonatal stages of digit formation in the mouse and found that regenerative capability correlated with the expression domain of the Msx1 gene. Using the stage 11 (E14.5) digit, we now sho...

0.94 ± 0.30 to female values of 0.961 ± 0.033.2 A separate study of adult male Han reported similar digit ratio values of 0.9478 ± 0.0322 for the right hand.3 Park and coworkers1 postulated that age may have had an effect on digit ratio, but if so, the effect must have been subtle since age was not significantly correlated with digit ratio in males or females in their study. Furthermore, the ut...

background: ratio of second and fourth digit (2d:4d) is known to be germane in analyzing utero concentrations of testosterone and estrogen in human and other vertebrates. 2d:4d had been linked several traits like athletes’ abilities, reproductive success, risk of cancer and cardiovascular disease (cvd). metabolic syndrome (mets) is a clustering of several cardiovascular risk factors. waist ci...

background and aim: dichotic digit test (ddt) is a valid neuropsychological tool for determining the dominant hemisphere in verbal processing; therefore, the main goal of this research was designing and investigating the psychometric properties of ddt in a sample of iranian children and then measuring its concurrent validity using the n-back task. methods: the present study was a descriptive an...

background: exposure to organic solvents is common among workers. objective: to assess neurobehavioral effects of long-term exposure to organic solvents among rubber workers in tehran, iran. methods: across-sectional study was conducted on 223 employees of a rubber industry. the participants completed a data collection sheet on their occupational and medical history, and demographic characteris...

although hand injuries due to kite strings seem to be trivial, these injuries could be serious enough to lose the function of hand. this case series in the division of plastic and reconstructive surgery of our institution from august 2014 to january 2016 evaluated the clinic-etiological profile, severity and management of hand injuries due to kite strings assessed clinically and radiologically....

The encoding and representation of visually presented clock times was investigated in three experiments utilizing a comparative judgment task. Experiment 1 explored the effects of comparing times presented in different formats (clock face, digit, or word), and Experiment 2 examined angular distance effects created by varying positions of the hands on clock faces. In Experiment 3, encoding and p...

In this article we study check character systems that is error detecting codes, which arise by appending a check digit an to every word a1a2...an−1 : a1a2...an−1 → a1a2...an−1an with the check formula (...((a1 · δa2) · δ 2a3)...) · δ n−2an−1) · δ n−1an = c, where Q(·) is a quasigroup or a loop, δ is a permutation of Q, c ∈ Q. We consider detection sets for such errors as transpositions (ab → ba...

In this paper, we present multipliers using a modified addition algorithm modulo m with a signed-digit(SD) number representation where m = 2 − 1, 2 or 2 + 1. To simplify an SD modular adder, new addition rules are proposed for generating the intermediate sum and carry with a binary number representation. By using the new codes for intermediate sum and carry and the end-around carry architecture...
