Controlled frames in Hilbert spaces have been recently introduced by P. Balazs and etc. for improving the numerical efficiency of interactive algorithms for inverting the frame operator. In this paper we develop a theory based on g-fusion frames on Hilbert spaces, which provides exactly the frameworks not only to model new frames on Hilbert spaces but also for deriving robust operators. In part...

aggregation operators (aos) have been studied by many schol- ars. as many aos are proposed, there is still lacking approach to classify the categories of ao, and to select the appropriate ao within the ao candidates. in this research, each ao can be regarded as a cognitive style or individual dierence. a cognitive style and aggregation operator (csao) model is pro- posed to analyze the mapping ...

objective: chronic myeloid leukemia (cml) is a malignant clonal disorder of hematopoietic stem cells which results in increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. investigations have shown different types of bcr- abl variants in these patients. in iran only 3 types of these variants have been identified because most of the clin...

objective(s): in this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (spect/ct) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. methods: five patients with primary hyperparathyroidism (phpt) and 4 patients with secondary hyperparathyroidism (shpt) we...

prosthetic joint infection (pji) is a serious complication of total knee arthroplasty (tka). control of infection after a failed two-stage tka is not always possible, and the resolution of infection may require an above-knee amputation (aka) or a the-knee (kf). the purpose of this review is to determine which treatment method (aka or kf) yields better function and ambulatory status for patients...

background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...

abstract   background: to evaluate proximal junctional segment changes in adolescent idiopathic scoliosis(ais) the posterior spinal fusion and also instrumentation also and finding of probable risk factors, were all considered in this study.   methods: we retrospectively reviewed radiographs of 121 consecutive patients who underwent posterior spinal fusion for ais from t3 or below, with a mean ...

background : anterior cervical discectomy and fusion (acdf) is an effective treatment for disc herniations ; but some studies demonstrated that in the untreated levels adjacent to a fusion, increased motion might lead to an increased risk of adjacent segment degeneration (asd). on the other hand, methods of cervical disc arthroplasty (cda) have improved. the aim of this study is to evaluate and...

remote sensing can be used as a powerful tool by using data from different sources and combine them for vegetation and land cover classification. pasture type classification provides key information for analysis of agricultural productivity, carbon accounting and biodiversity. the first data set that used in this study landsat tm (thematic mapper) optical image and the second envisat asar radar...
