Background: Down syndrome is the most common genetic intellectual disability conditions in 1 out of 800 to1000 live births. Adolescents and youth with Down syndrome are unique population on physical fitness factors related to health. Method: To investigate the factors of physical fitness and physical activity in adolescents and youth with Down syndrome the international and national da...
Objectives: Sensory integration training plays a crucial role on the attention span and motor skills of students with Down syndrome. The present research aimed to investigate the effect of sensory integration training on the attention span and motor skills of students with Down syndrome. Methods: This was a quasi-experimental research with a pretest, posttest design and control group. Partici...
The paper is about methodology to detect and demonstrate impossible differentials in a block cipher. We were inspired by the shrinking technique proposed by Biham et al. [2,3] in 1999 which recovered properties of scalable block cipher structures from numerical search on scaled down variants. Attempt to bind all concepts and techniques of impossible differentials together reveals a view of the ...
This paper proposes a method for adaptive testing that is less complicated than the commonly used transformed up-down methods (1 up 2 down, 1 up 3 down, etc.). In addition, the weighted up-down method can converge to any desired point of the psychometric function. The rule is very simple: Each correct response leads to a decrease in signal level, each incorrect response to an increase. The only...
Background & Objective: Down syndrome is one of the most common chromosome aneuploidies causing mental retardation which occurs in approximately 1/230 pregnancies. It is usually caused by the presence of an extra chromosome 21. The aim of this study was to evaluate the simple PCR based DNA diagnostic method and also to determine the parental origin of the extra chromosome 21 in trisomal Down sy...
Association Rule mining is one of the important and most popular data mining techniques. It extracts interesting correlations, frequent patterns and associations among sets of items in the transaction databases or other data repositories. Apriori algorithm is an influential algorithm for mining frequent itemsets for Boolean association rules. Firstly, the concept of association rules is introdu...
We demonstrate a method for inducing strain in carbon nanotubes using standard lithographic techniques. In this work, aligned nanotubes are partially suspended over trenches made by chemical etching. Strain-induced downshifts as high as 31 cm−1 are observed in the Raman spectra, roughly corresponding to 1.1% strain. We also observe significant shifts in the resonant transition energy Eii and an...
