Naturally, deformed rocks commonly contain crack arrays (joints) forming patterns with systematic relationships to the large-scale deformation. Kinematically, joints can be mode-1, -2 or -3 or combinations of these, but there is no overarching theory for the development of the patterns. We develop a model motivated by dislocation pattern formation in metals. The problem is formulated in one dim...

We extend the mechanism for noise-induced phase transitions proposed by Ibañes et al. [Phys. Rev. Lett. 87, 020601 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not driven by a short-time instability amplified by collective effects. The phenomenon is analyzed by means of a modulated mean field approximation ...

abstract background: professional development is reiterated in the new definition of modern organizations as a serious undertaking of organizations. this article aims to present and describe a prescriptive model to increase the quality of professional development of iranian nurses within an organization‑based framework. materials and methods: this article is an outcome of the results of a study...

The customers ’preference is derived from reflection on a product or special commercial brand, and factors such as positive appraisal of a brand performance and holding advantages and being unique, establishes the preference. This study aimed to develop a model of female customers' preferences in selecting banks and to train senior managers and banking staff. It had an applied objective, adopte...

The purpose of this study is to present a model for employee absenteeism management using Grounded Theory (GT). Since there is a lack of study on theorizing this construct, this study aimed to conceptualize a theoretical model applying GT. This research is a qualitative research. The sample size was 11 interviewers who were knowledgeable human resource and organizational experts. Required data ...

In order to identify the dimensions and indices of the phenomenon of “leading transfer of learning” within the secondary schools of Tehran province, a sample of 17 lecturers, principals, and experienced teachers was targeted and then interviewed. Inductive analyses of the collected data at three levels of open, pivotal, and selective coding indicate that the role of high school principals along...

The paper solves the main open problem of [BFG94]. We show that given two dependence alphabets (Σ, D) and (Σ′, D′), it is decidable whether there exists a strong coding h : M(Σ, D) −→ M(Σ′, D′) between the associated trace monoids. In fact, we show that the problem is NP-complete. (A coding is an injective homomorphism, it is strong if independent letters are mapped to independent traces.) We e...

Genome annotation in differently evolved organisms presents challenges because the lack of sequence-based homology limits the ability to determine the function of putative coding regions. To provide an alternative to annotation by sequence homology, we developed a method that takes advantage of unusual trypanosomatid biology and skews in nucleotide composition between coding regions and upstrea...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...

The transcription of mammalian genomes exhibits an intriguing complexity and numerous novel RNA molecules have been identified. Viruses with large DNA genomes, especially herpesviruses, generate many different species, including long non-coding RNAs (lncRNAs). Dense viral can multigenic transcripts in addition to commonly observed antisense transcripts. It is essential study the biological role...
