results seven concepts emerged after exploratory factor analysis of the 48 items. the content validity ratio (cvr) of the questionnaire constructs were 0.55 to 0.76, and content validity index (cvi) structure was 0.86 to 0.95. cronbach's alpha coefficient for the entire questionnaire was 0.78, and correlation coefficient of the test-retest reliability for the constructs was from 0.73 to 0.89. c...

Abstract Background Neurological injuries such as stroke often differentially impair hand motor and somatosensory function, well the interplay between two, which leads to limitations in performing activities of daily living. However, it is challenging identify specific aspects sensorimotor function are impaired based on conventional clinical assessments that insensitive subjective. In this work...

background: numerous studies used microarray gene expression data to extract metastasis-driving gene signatures for the prediction of breast cancer relapse. however, the accuracy and generality of the previously introduced biomarkers are not acceptable for reliable usage in independent datasets. this inadequacy is attributed to ignoring gene interactions by simple feature selection methods, due...

In 2012, Singh and Verma proposed an ID-based proxy signature scheme with message recovery. In this paper, we show that their scheme is vulnerable to the forgery attack, and an adversary can forge a valid proxy signature for any message with knowing a previous valid proxy signature. In addition, there is a security flaw in their proof. Furthermore, we propose an improved scheme that remedies th...

Zimbardo, DOI 10.1007/978-3-319-07368-2_2, © Springer International Publishing Switzerland 2015 Although Einstein’s theory of relativity ( 1931 ) established the subjective nature of the physical phenomenon of time, the signifi cance of the psychological interpretation of this rel...

On-line dynamic signature verification systems were designed and tested. A data base of more than 10,000 signatures in (I, y(t))-form was acquired using a graphics tablet. We extracted a 42-parameter feature set at first, and advanced to a set of 49 normalized features that tolerate inconsistencies in genuine signatures while retaining the power to discriminate against forgeries. We studied alg...

In this paper, we propose a forward secure ring signature scheme without random oracles. With forward security, if a secret key of a corresponding ring member is exposed, all previously signed signatures containing this member remain valid. Yet the one who has stolen the secret key cannot produce any valid signature belonged to the past time period. This is especially useful in the case of ring...

introduction. students' evaluation of teaching is a major concern in higher education. in this regard, during the past 30 years hundreds of papers have been published which because of various grounds from valid, reliable to useless, such papers cannot be easily summarized. the present study investigated for two purposes, first was to out line opinions of two groups of advocates and opposit...
