Dry eye syndrome is one of the most commonly reported eye health conditions. Dynamic-area high-speed videokeratoscopy (DA-HSV) represents a promising alternative to the most invasive clinical methods for the assessment of the tear film surface quality (TFSQ), particularly as Placido-disk videokeratoscopy is both relatively inexpensive and widely used for corneal topography assessment. Hence, im...

A representation theoretical characterization of an Hadamard subset is given. §l. Introduction. A finite group G of order 2n is called an Hadamard group if G contains an n-subset D and an element e* such that (1) D and De*,are disjoint, (2) D and Da intersect exactly in n/2 elements for any element a of G distinct from e* and the identity element e of G, and (3) Da and {b, be*} intersect exactl...

Abstract This study aimed to examine the impacts of computerized dynamic assessment (C-DA) and rater-mediated on test anxiety, writing performance, oral proficiency Iranian EFL learners. Based Preliminary English Test (PET) results, a sample 64 intermediate participants was chosen from 93 students. Running convenience sampling technique, target test-takers were randomly divided into experimenta...

conclusions a short-term wbv exercise improves isotonic strength of the leg muscle and dynamic balance, while creatine supplementation with and without wbv training increases isometric strength of the leg muscle and mobility in elderly women. background a decline in neuromuscular function can cause a decrease in physical fitness in elderly women. objective the present study aimed at investigati...

Group signatures allow members to sign on behalf of a group. Recently, several schemes have been proposed, in order to provide more efficient and shorter group signatures. However, this should be performed achieving a strong security level. To this aim, a formal security model has been proposed by Bellare, Shi and Zang, including both dynamic groups and concurrent join. Unfortunately, very few ...

Divided attention (DA), the ability to distribute cognitive resources among two or more simultaneous tasks, may be severely compromised after traumatic brain injury (TBI), resulting in problems with numerous activities involved with daily living. So far, no research has investigated whether the use of non-invasive brain stimulation associated with neuropsychological rehabilitation might contrib...

Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic cytokine which controls the differentiation and growth of hematopoietic cells in the bone marrow. We report a severe aplastic anemia (SAA) patient with false-negative 99mTc sodium phytate bone marrow imaging findings under concurrent G-CSF therapy. The first bone marrow imaging showed a normal bone marrow activity. However, the bo...
