rice sheath blight disease caused by rhizoctonia solani ag1- ia is the secondeconomically important disease of the crop in most rice- growing regions of the world,including northern of iran. the disease is mainly controlled through application of fungicides.the present study was performed to identify the candidate cultivar (cultivars) as source ofresistance to the pathogen in rice field conditi...

A unifying framework for game tree algorithms is GSEARCH, designed by Ibaraki Ibaraki 86]. In general, a relatively great deal of memory is necessary for instances of this framework. In Ibaraki 91A] an extended framework, called RSEARCH, is discussed, in which the use of memory can be controlled. In this paper variants of above frameworks are introduced, to be called Gsearch and Rsearch respect...

Background: Sleep Seizures (SSs) generally occur in refractory focal epilepsy, but their detailed characteristics and circadian patterns are still controversial. The effect of SSs on epilepsy surgery outcome has been addressed in few studies without definitive prognostic value.   Objectives: This study investigated the characteristics of SSs and their prognosis in refractory focal epilepsy. M...

The IEEE 802.16 standard for wireless metropolitan area networks (WMANs) is designed to satisfy various demands for high capacity, high data rate, and advanced multimedia services (Abichar et al., 2006). The medium access control (MAC) layer of IEEE 802.16 networks supports both point-to-multipoint (PMP) and mesh modes for packet transmission (IEEE Std. 802.16-2004, 2004). Based on the applicat...

Objective: Somatic symptom disorder (SSD) is characterized by somatic symptoms that are very distressing or cause considerable functional disability. SSD is associated with various medical and psychiatric conditions and imposes high costs on the patient's health care system. Therefore, diagnosis and treatment of SSD are crucial. The Somatic Symptom Scale-8 (SSS-8) is a valuable and brief self-r...

This paper summarizes recent analytical Invest igations of the mathematical properties of heuris­ t ics and the i r Influence on the performance of common search techniques. The results are reported without proofs, together with discussions of moti­ vations and Interpretations. Highlights include the fol lowing: relations between the precision of the heurist ic estimates and the average complex...

Well-known algorithms for the evaluation of the minimax function in game trees are alpha-beta Knuth] and SSS* Stockman]. An improved version of SSS* is SSS-2 Pijls-1]. All these algorithms don't use any heuristic information on the game tree. In this paper the use of heuristic information is introduced into the alpha-beta and the SSS-2 algorithm. Extended versions of these algorithms are presen...

PURPOSE The identification of sick sinus syndrome (SSS) in patients with atrial flutter (AFL) is difficult before the termination of AFL. This study investigated the patient characteristics used in predicting a high risk of SSS after AFL ablation. MATERIALS AND METHODS Out of 339 consecutive patients who had undergone radiofrequency ablation for AFL from 1991 to 2012, 27 (8%) had SSS (SSS gro...

Carpal tunnel syndrome (CTS) is a neuropathy due to the compression of the median nerve. It is shown that gabapentin in high doses is effective in treatment of CTS patients. In this study we evaluated the efficacy of low doses of gabapentin in treatment of CTS patients. Ninety patients with CTS were randomly assigned to groups A, B and C. Gabapentin was administered to group A with dose of 100 ...
