objectives: strr is a putative pathway specific regulator of streptomycin production in streptomyces griseus. because of finding new spo0j domain in strr by bioinformatics methods, the purpose of this study was to suggest another role for strr gene. this domain can be seen in proteins that are involved in initiation of sporulation and normal chromosome partitioning. so, 51 bps of strr in accord...

In this work, a new mathematical model of thermoelasticity theory has been considered in the context of a new consideration of heat conduction with fractional order theory. A functionally graded isotropic unbounded medium is considered subjected to a periodically varying heat source in the context of space-time non-local generalization of three-phase-lag thermoelastic model and Green-Naghdi mod...

after the introduction of postmethod pedagogy by kumaravadivelu with its three principles of particularity, possibility and practicality, a wave of attention was directed towards this so-called 'postmethod era' and its appropriacy and adequacy in satiating the demands of the language learners in this 'brand new world'. this situation has created a healthy debate among the iranian efl community ...

Existing research on sentiment analysis mainly uses sentiment words and phrases to determine sentiments expressed in documents and sentences. Techniques have also been developed to find such words and phrases using dictionaries and domain corpora. However, there are still other types of words and phrases that do not bear sentiments on their own, but when they appear in some particular contexts,...

The Hybrid Learning System (HLS) inductively learns concepts and is a hybrid of a genetic classiier system and a similarity-based learner. Its basic structure is a genetic algorithm that applies a local search operator to population members. This study compares ID3, a standard genetic classifer system, and HLS for accuracy and concept conciseness on a variety of problem domains with and without...

Introduction: The Magnetisation Transfer (MT) effect is based on the exchange of magnetisation between two proton pools; ‘free’ (‘liquid’) and ‘restricted’ (macromolecular). This property allows the MR characteristics of the macromolecular component (usually ‘invisible’ using conventional MRI due to its very short T2) to be probed via selective saturation. Analysis is based on a 2-pool quantita...

Object-oriented methods aim at providing natural ways for decomposing (or composing) a system into (from) objects that correspond to concepts in the customer’s problem domain. The identified objects are the basic building blocks of the object-oriented system to be constructed. In order not to disregard relevant objects, most methods advise software engineers to take dedicated steps such as read...

this paper presents a new three-dimensional curvelet transform based dictionary learning for automatic segmentation of intraretinalcysts, most relevant prognostic biomarker in neovascular age-related macular degeneration, from 3d spectral-domain optical coherencetomography (sd-oct) images. in particular, we focus on the spectralis sd-oct (heidelberg engineering, heidelberg, germany) system, and...
