EPC is a known coding scheme for RFID equipment. This paper suggest a scheme of an efficiently compression for EPC.
OBJECTIVE Reduced levels and impaired function of endothelial progenitor cells (EPCs) foster development and progression of atherosclerotic lesions. Endothelial nitric oxide synthase (eNOS)-derived NO regulates EPC mobilization and function. Organic nitrates release NO, and therefore may favorably affect EPC biology. METHODS AND RESULTS We compared the effects of 2 different nitrates on circu...
BACKGROUND Stromal cell-derived factor-1 (SDF1) and its receptor CXC chemokine receptor 4 (CXCR4) play a critical role in progenitor cell homing, mobilization and differentiation. It would be interesting to assess the predictive value of SDF-1alpha level for EPC number, and to ascertain whether there is a relationship between SDF1 gene variation, plasma SDF-1alpha level, and the number and func...
Nepenthes alata-inspired micro/nano-textured lubricant-infused surface (LIS) has shown strong potential in the fields of drag reduction (DR), anti-biofouling, and self-cleaning. However, its surface-slippery property is largely degraded under turbulent shear flow conditions due to loss impregnated oil. This condition inhibits practical applications marine vehicles. The mucus-impregnated tissue ...
Nowadays, most process modelling tools implement popular modelling languages such as the Business Process Model and Notation (BPMN) or the Event-driven Process Chain (EPC). However, in contrast to BPMN, no effort has yet been undertaken to standardize the EPC language, thus rendering EPCs as being merely a de-facto standard for business process modelling. Subsequently, this paper addresses this...
Resumo O estudo descreve a criação e validação da Escala de Percepção Corrupção (EPC), que se propõe avaliar como o cidadão percebe corrupção. Na construção EPC, em etapa qualitativa, instrumento foi avaliado por especialistas, seguido pré-teste. Já na quantitativa, realizou-se análise fatorial exploratória confirmatória, totalizando amostra 1075 casos. Por fim, sugere-se uma metodologia para a...
Next-generation RNA sequencing was employed to determine the acute and subchronic impact of peristaltic pulse external pneumatic compression (PEPC) of different target inflation pressures on global gene expression in human vastus lateralis skeletal muscle biopsy samples. Eighteen (N = 18) male participants were randomly assigned to one of the three groups: (1) sham (n = 6), 2) EPC at 30-40 mmHg...
Since the electronic power conditioner (EPC) is a crucial part of space traveling-wave tube amplifier (STWTA), its reliability issue must be considered. The most effective way to prevent insulation breakdown potting. Silicone elastomers are commonly used as an encapsulant for EPC because their good physical and electrical properties. properties interfaces change under influence γ-radiation, whi...
The exergetic analysis is a tool that has been used successfully in many studies aiming a more rational energy consumption to reduce the cost of processes. With this analysis, it is possible to perform an evaluation of the overall process, locating and quantifying the degradation of exergy. This paper applies exergy approach for analyzing the heat exchanger network design and refrigeration of M...
Patients with end-stage renal disease (ESRD) on hemodialysis have an increased risk of cardiovascular disease (CVD). Circulating endothelial progenitor cells (EPC) contribute to vascular regeneration and repair, thereby protecting against CVD. However, circulating smooth muscle progenitor cells (SPC) may contribute to adverse vascular remodeling. We hypothesized that an imbalance occurs between...
