In his seminal paper, Mayr introduced the well-known Process Rewrite Systems (PRS) hierarchy, which contains many wellstudied classes of infinite-state systems including pushdown systems, Petri nets and PA-processes. A seperate development in the term rewriting community introduced the notion of Ground Tree Rewrite Systems (GTRS), which is a model that strictly extends pushdown systems while st...

Pull-based development has enabled numerous volunteers to contribute open-source projects with fewer barriers. Nevertheless, a considerable amount of pull requests (PRs) valid contributions are abandoned by their contributors, wasting the effort and time put in both contributors maintainers. To better understand underlying dynamics contributor-abandoned PRs, we conduct mixed-methods study using...

Patient Registration System (PRS) is an important part of hospital environment. Therefore, semiformal model of Patient Registration System that registers the patients by assigning Radio Frequency Identification (RFID) card or bracelet is presented in this paper. The existing Patient Registration Systems do not properly work due to ambiguities and semiformal modeling techniques. However, that is...

The outcome for patients with relapsed Ewing's sarcoma is poor. A retrospective analysis was carried out to identify factors associated with improved survival. Between 1992 and 2002, 114 patients presented with relapsed or progressive disease. Median time to progression/relapse was 13 months (range, 2-128). Treatment at relapse included high dose treatment (HDT) in 29 patients, and surgery or d...

We have constructed a set of 42 plasmid shuttle vectors based on the widely used pRS series for use in the budding yeast Saccharomyces cerevisiae and the bacterium Escherichia coli. This set of pRSII plasmids includes new shuttle vectors that can be used with histidine and adenine auxotrophic laboratory yeast strains carrying mutations in the genes HIS2 and ADE1, respectively. Our pRSII plasmid...

One of the most exciting trends in schizophrenia research is the shift in focus from treatment studies to studies about the early identification and prevention of schizophrenia. These studies have primarily focused on adolescents or young adults with prodromal symptoms or on clinically high-risk individuals who show similar impairments in cognitive and social functioning to those seen in indivi...

Purpose: The ability to generate macaque retinas with sortable cell populations would be of great benefit to both basic and translational studies of the primate retina. The purpose of our study was therefore to develop methods to achieve this goal by selectively labeling, in life, photoreceptors (PRs) and retinal ganglion cells (RGCs) with separate fluorescent markers. Methods: Labeling of maca...

METHODS: Twenty-five patients were selected for PRP therapy for facial rejuvenation. All patients completed the following FACE-Q scales preprocedure: appearance appraisal, quality of life, adverse effect checklists for treatment, and process of care. PRP was prepared using a standardized protocol. At 6 weeks posttreatment, another FACE-Q was completed, and 2 blinded observers (1 plastic surgeon...

Emerging data indicate that progesterone has multiple non-reproductive functions in the central nervous system to regulate cognition, mood, inflammation, mitochondrial function, neurogenesis and regeneration, myelination and recovery from traumatic brain injury. Progesterone-regulated neural responses are mediated by an array of progesterone receptors (PR) that include the classic nuclear PRA a...

There is an increasing interest in researchers and companies on the combination of Distributed Acoustic Sensing (DAS) and a Pattern Recognition System (PRS) to detect and classify potentially dangerous events that occur in areas above fiber optic cables deployed along active pipelines, aiming to construct pipeline surveillance systems. This paper presents a review of the literature in what resp...
