In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...

sulfur mustard (sm) gas was used in the iran-iraq war (1981 - 1989) as a vesicant chemical warfare against the iranian warriors. this alkylating agent with the potential of producing chemical injury in the skin, eyes, and lung, may damage both upper and lower respiratory tract, which in turn can cause different types of sequels such as asthma, bronchiectasis, chronic bronchitis and lung fibrosi...

background and aim: electrical discharges in temporal lobe epilepsy can cause disorders in auditory pathways. staggered spondaic word test ( ssw) is one of the most common behavioral tests to evaluate the central auditory nervous system. this study aimed to evaluate and compare auditory processing problems in temporal lobe epileptic patients and normal subjects with persian ssw test. methods: t...

epilepsy is one of the most common neuroinflammatory disorders that affect more than 50 million people worldwide. excessive electrical discharges in neurons following neural cell damage or loss leads to recurrent seizures, which are described as epilepsy. one of the most common and difficult to treat types of epilepsy is temporal lobe epilepsy (tle), which results from hippocampal sclerosis. cu...

introduction : shared neuropathology hypothesis in schizophrenia and temporal lobe epilepsy has been introduced long term ago. similar neuropathology leads to the analogous clinical features like neuropsychological features as an example. the aim of this study was to examine this hypothesis by the means of comparing neuropsychological functions in these two patient groups. method : present stud...

background and objective: temporal lobe epilepsy (tle) is a chronic neurological disorder with spontaneous recurrent seizures and abnormal intracranial waves. since the role of oxidative stress in the occurrence of epilepsy is inevitable, it seems that the use of antioxidants can prevent some of the complications resulting from this disease. this study was designed to assess the protective effe...

The empirical foundation of executive control function (ECF) remains controversial. We have employed structural equation models (SEM) to explicitly distinguish domain-specific variance in executive function (EF) performance from memory (MEM) and shared cognitive performance variance, i.e., Spearman's "g." EF does not survive adjustment for both MEM and g in a well fitting model of data obtained...

Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea-orthodeoxia syndrome in a young woman with acute atelectasis due to post-tuberculo...

A patient with migraine who had a permanent visual field defect was studied by angiography and CT scan. He also had a tomographic study of cerebral blood flow (CBF) and oxygen extraction fraction (EO2) using the non-invasive continuous oxygen-15 (15O) inhalation technique. Angiography was normal. CT scan revealed an area of decreased density with contrast enhancement suggestive of a recent infa...

It remains unclear how single neurons in the human brain represent whole-object visual stimuli. While recordings in both human and nonhuman primates have shown distributed representations of objects (many neurons encoding multiple objects), recordings of single neurons in the human medial temporal lobe, taken as subjects' discriminated objects during multiple presentations, have shown gnostic r...
