background: to understand the relapse process, it is required to notice the clients learned behaviors and environmental contexts. we aimed to explore and describe relapse experiences of iranian drug users. methods: this is a grounded theory study and twenty two participants were selected using purposive sampling, snowball and theoretical sampling. after obtaining written informed consent, data ...

a large part of the country's industrial and manufacturing units are small and medium enterprises, but these firms have not been able to play an important contribution to achieving the export development goals. given the importance of export promotion as the engine of the economy and low export share of smes, the purpose of this study is explanation the policy of export promotion for this ...

Five theories of how letter position is coded are contrasted: position-specific slot-coding, Wickelcoding, open-bigram coding (discrete and continuous), and spatial coding. These theories make different predictions regarding the relative similarity of three different types of pairs of letter strings: substitution neighbors, neighbors-once-removed, and double-substitution neighbors. In Experimen...

The aim of this study is to present a comprehensive human resources model based on ISO34000 standard at Khorasan Razavi Electricity Distribution Company. This study is mixed, sequential exploratory, and applied. The qualitative population was the experienced and scientific experts. The quantitative population was 153 managers, deputies and experts responsible for the electricity company selecte...

MOTIVATION Long non-coding RNAs (lncRNAs), which are non-coding RNAs of length above 200 nucleotides, play important biological functions such as gene expression regulation. To fully reveal the functions of lncRNAs, a fundamental step is to annotate them in various species. However, as lncRNAs tend to encode one or multiple open reading frames, it is not trivial to distinguish these long non-co...

This paper evaluates two temporally scalable video coding techniques, temporal subband coding (TSB) and predictive coding, both theoretically and in practice to provide comparisons of compression and visual quality at differing frame rates. An emphasis is placed on evaluating only the visual effects caused by the temporal coding technique rather than those introduced by any spatial coding. Resu...

We report on the large-scale acquisition of class attributes with and without the use of lists of representative instances, as well as the discovery of unary attributes, such as typically expressed in English through prenominal adjectival modification. Our method employs a system based on compositional language processing, as applied to the British National Corpus. Experimental results suggest ...

This paper introduces the Kodo network coding library. Kodo is an open source C++ library intended to be used in practical studies of network coding algorithms. The target users for the library are researchers working with or interested in network coding. To provide a research friendly library Kodo provides a number of algorithms and building blocks, with which new and experimental algorithms c...
