conclusions the most effected parts in asd are lateral connections of hmasd. two-sided connections which are completely symmetric become more active, and cause extra synchronization. on the other hand, due to special characteristic of two-sided connections and their ability to simulate the same phased dynamics, they cause unnatural asymmetry in children’s eeg signal. these results are consisten...
unilateral condylar hyperplasia is the main cause of mandibular asymmetry. radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. in this study, 39 patients with normal bone scan and no facial asymmetry were studied. all patients were below 22 years of age. normal condylar uptake was determined in this group of patients. right & left condylar ...
Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...
In this paper various ARCH models and relevant news impact curves including a partially nonparametric (PNP) one are compared and estimated with daily Iran stock return data. Diagnostic tests imply the asymmetry of the volatility response to news. The EGARCH model, which passes all the tests and appears relatively matching with the asymmetry in the data, seems to be the most adequate characteriz...
این مقاله ارتباط بین ایدئولوژیهای اخلاقی و مسئولیتپذیری اجتماعی را با عدم تقارن اطلاعاتی در شرکتهای پذیرفته شده در بورس اوراق بهادار تهران بررسی میکند. در این پژوهش برای سنجش ایدئولوژیهای اخلاقی و مسئولیتپذیری اجتماعی به ترتیب از پرسشنامههای استاندارد سنجش موقعیت اخلاقی فورسیث (1980) و سینگاپکدی استفاده شده است. همچنین برای سنجش متغیر عدم تقارن اطلاعاتی از فاصله قیمت پیشنهادی خرید و فروش...
the highly conserved morphology and chromosomal structures of house mouse, mus musculus, provides a good model for chromosomal studies. sex-autosome translocations is one of the rarest chromosomal rearrangements among mammals and therefore sex-autosome translocations has been offered as accurate taxonomic markers to identify species with similar morphological traits. in this study, we described...
Introduction: Alzheimer’s disease (AD) is the most common cause of dementia worldwide. Mild cognitive impairment (MCI) is often the prodromal stage to AD. Most patients with MCI harbor the pathologic changes of AD and demonstrate transition to AD at a rate of 10–15% per year. Accumulating evidence indicates that the asymmetry changes of left and right brain have happened in the early stage of A...
torsion of many symmetric structures, which were designed based on the seismic codes, is due to their asymmetricity induced during inelastic behavior. although the structure was designed symmetrically assuming elastic based criteria, different factors such as material inconsistency in structure, construction details discrepancy and construction errors may result in asymmetric behavior in inelas...
عدم تقارن اطلاعات عامل مهمی است که میتواند اثرات زیادی بر بازارهای مالی برجا بگذارد. یکی از این موارد اثرگذاری، بر بازده سهام و حجم معاملات در شرکتهای بورس اوراق بهادار است که میزان اثرگذاری آن نیاز به بررسی دارد. در این راستا مطالعه حاضر با استفاده از مدل احتمال مبادله آگاهانه (PIN) به بررسی این موضوع پرداخته است. نتایج به دست آمده از مطالعه نشان داد که عدم تقارن اطلاعات در کل بر بازده سهام ...
migraine is a neurologic disease, which often is associated with a unilateral headache. vestibular abnormalities are common in migraine. vestibular evoked myogenic potentials (vemps) assess otolith function in particular functional integrity of the saccule and the inferior vestibular nerve. we used vemp to evaluate if the migraine headache can affect vemp asymmetry parameters. a total of 25 pat...
