PURPOSE To compare dosimetric and treatment delivery parameter differences between volumetric-modulated arc radiotherapy (VMAT) and intensity-modulated radiotherapy (IMRT) for large volume retroperitoneal sarcomas (RPS). MATERIALS AND METHODS Both VMAT and IMRT planning were performed on CT datasets of 10 patients with RPS who had been previously treated with preoperative radiotherapy. Plans ...

Ribosomal proteins (RPs) are indispensable in ribosome biogenesis and protein synthesis, and play a crucial role in diverse developmental processes. Our previous studies on Ribosomal Protein Large subunit (RPL) genes provided insights into their stress responsive roles in rice. In the present study, we have explored the developmental and stress regulated expression patterns of Ribosomal Protein...

Many states have adopted policies aimed at promoting the growth of renewable electricity within their state. The most salient of these policies is a renewable portfolio standard (RPS) which mandates that retail electricity providers purchase a predetermined fraction of their electricity from renewable sources. Renewable portfolio standards are a policy tool likely to persist for many decades du...

Assessing the research output within the universities could provide an effective means for tracking the Millennium Development Goals (MDGs) progress. This analytical database study was designed to assess the trend of research theses conducted by the Public Health Department (PHD), Faculty of Medicine, Cairo University during the period 1990 to 2014 as related to the: MDGS, Faculty and departmen...

This paper analyses the application of hierarchical classifiers based on the k-NN rule to the automatic classification of handwritten characters. The discriminating capacity of a k-NN classifier increases as the size of the reference pattern set (RPS) increases. This supposes a problem for k-NN classifiers in real applications: the high computational cost required when the RPS is large. In orde...

Over the past decade, state policies on renewable energy have been on the rise in the United States, providing states with various options for encouraging the generation of renewable electricity. Two promising policies, the Renewable Portfolio Standard (RPS) and the Mandatory Green Power Option (MGPO), have been implemented in many states but the evidence about their effectiveness is mixed. In ...

OBJECTIVES To report the utilization of a new transoral surgery system, i.e. transoral videolaryngoscopic surgery (TOVS) with a navigation system, for the removal of a metastatic retropharyngeal lymph node (RPLN). CASE REPORT An 86-year-old woman with tongue cancer (cT2N0M0) underwent partial glossectomy and left selective neck dissection. Three months postoperatively, a left metastatic RPLN ...

Transplantation of retinal cells has recently provided a promising therapeutic approach for retinal degeneration. Here, we differentiated initially retinal progenitors (RPs) from adherent feeder-free human embryonic stem cells (hESCs) with the use of defined media supplemented with a specific combination of growth factors. The differentiated RPs highly (>80%) expressed related molecular feature...

We describe new ESS models of density regulation driven by genic selection to explain the cyclical dynamics of a social system that exhibits a rock-paper-scissors (RPS) set of three alternative strategies. We tracked changes in morph frequency and fitness of Lacerta vivipara and found conspicuous RPS cycles. Morphs of Uta and Lacerta exhibited parallel survival-performance trade-offs. Frequency...

BACKGROUND AND PURPOSE Recent movement analysis studies have described compensatory movement strategies used by people with hemiparesis secondary to stroke during reaching and grasping tasks. The purpose of this article is to describe the development of a new scale--the Reaching Performance Scale (RPS)--for assessing compensatory movements for upper-extremity reaching in people with hemiparesis...
