چکیده
Positron lif etimes and Do ppler broadening of the annihi l atio n line mea surements were perf ormed to study the vacancy typ e defects in polycrystallin e GeT e and (GeT e) ( 1 À x ) (A gBiT e2 ) x ( = 0 0 0 3 0 05 0 1 0 15 0 2, and 1) solid solutio ns. The values of lif etimes obtained are explaine d as due to positron and p ositronium saturated trapping at vacancies and vacancy clusters. T he interdep endence betw een mean positron lif etime and hole concentration is discussed. PACS numb ers: 78.70.Bj

VALUE OF INT ER-ICTAL SURFACE EEG IN THE DIAGNOSIS OF SEIZURE DISORDERS IN CHILDREN: A LOCAL ST UDY
We wished to assess the frequency of EEG positivity with our available EEG technology to compare with those elsewhere. Between April 1996 to February 1997, of patients referred to the Pediatric Neurology Out-patient Clinic for assessment of seizure disorders, 202 randomly selected patients aged 16 months to 17 years (mean 8.96 years) underwent a 10-minute inter-ictal EEG recording using a ...
متن کاملIbuprofen-Loaded CTS/nHA/nBG Scaffolds for the Applications of Hard Tissue Engineering
Background: This study addressed the development of biodegradable and biocompatible scaffolds with enhanced biomechanical characteristics. The biocompatibility and the cationic nature of chitosan (CTS) make it more effective as a bone grafting material. Methods: The hydroxyapatite nanoparticles (nHA) were synthesized by hydrothermal method, and bioglass (nBG) (50% SiO2-45% CaO-5% P2O5) was synt...
متن کاملA COMPARATIVE ST UDY OF THERAPEUTIC RESULTS OF RIGH T AND LEFT COLONIC INJURIES SUSTAINED BY IRANIAN SOLDIERS IN THE IRAN-IRAQ WAR
The treatment strategy of colonic injuries is a debatable and highly controversial subject worldwide in various medical centers. The method of treatment of left and .. right colonic injuries, diversity or similarity in their management and particularly differences between the treatment of war-associated injury from other types of colonic damage are among the unsettled issues. The present s...
متن کاملDeep Extreme Feature Extraction: New MVA Method for Searching Particles in High Energy Physics
In this paper, we present Deep Extreme Feature Extraction (DEFE), a new ensemble MVA method for searching ττ channel of Higgs bosons in high energy physics. DEFE can be viewed as a deep ensemble learning scheme that trains a strongly diverse set of neural feature learners without explicitly encouraging diversity and penalizing correlations. This is achieved by adopting an implicit neural contro...
متن کاملChanges in Dermatomal Somatosensory Evoked Potentials according to Stimulation Intensity and Severity of Carpal Tunnel Syndrome
OBJECTIVE To investigate the change of latency of cervical dermatomal somatosensory evoked potential (DSEP) according to stimulation intensity (SI) and severity of carpal tunnel syndrome (CTS). METHODS Stimulation sites were the C6, C7, and C8 dermatomal areas. Two stimulation intensities 1.5×sensory threshold (ST) and 2.5×ST were used on both normal and CTS patients. RESULTS In moderate CT...
