Congestion control in resilient packet ring networks
The Resilient Packet Ring (RPR) is a new metro technology; RPR shares SONET's ability in providing fast recovery from link and node failures as well as inherits the cost and simplicity of Ethernet. RPR, like SONET/SDH, is a ring based architecture consisting of two optical rotating rings …

Genetic analysis of programmed cell death in Drosophila melanogaster
… proteases. In Drosophila, the proteins, Reaper (Rpr), Head involution defective (Hid), and Grim, induce cell death via a mechanism that involves caspase activation. In order to further elucidate the mechanisms underlying the control of apoptosis, we conducted screens for genes involved in Rpr- or …

Death by Frustration: How Defects in Cell Differentiation Trigger Apoptosis
… confirmation of their epistatic relationship to rpr, hid, and grim and have revealed that they may work synergistically. rpr indirectly activates caspases by derepressing their inhibitors, and many proapoptotic signals trigger its transcriptional upregulation. An analysis of its promoter …

An authoring tool of photo-realistic virtual objects for augmented reality
… fotorrealística. A ferramenta, denominada RPR-SORS Editor, utiliza uma API de fotorrealismo (RPR-SORS) e tem como foco a criação e edição de objetos virtuais. A ferramenta desenvolvida é capaz de manipular de forma interativa os parâmetros de materiais do RPR-SORS e do motor de renderização …

Syphilis in Pregnancy: Exploring the prevalence and vertical transmission prevention cascade of syphilis using routinely collected electronic health data, Cape Town Metropolitan District, 2017–2022
… TPAb (Treponema pallidum antibody) and RPR (rapid plasma reagin) results were reviewed. Results: 419 376 pregnancies were identified, resulting in 425 128 outcomes. 47% of pregnancies had a documented laboratory syphilis test, with 6812 (1.6%) of total pregnancies testing RPR positive. A …

Novel algorithms for fair bandwidth sharing on counter rotating rings
… in 2004 by the IEEE Resilient Packet Ring (RPR) Working Group. Since then two addenda have been introduced; namely, IEEE 802.17a and IEEE 802.17b in 2006 and 2010, respectively. During this standardization process, weighted fairness and queue management schemes were proposed to be used in …

Error -Tolerant Digital Signal Processing
… referred to as reduced precision redundancy (RPR), which can be easily integrated to any DSP system. Combined with voltage overscaling (VOS), RPR achieves desired performance with considerable energy savings. We extend forward predictor-based ANT and present hybrid ANT and forward-backward …

Resistance training and recovery: influence of dietary supplements, combined trreatment therapies, and gender
… muscle pain and ratings of perceived recovery (RPR) were measured 24 h after the initial workout. Muscle recovery was defined as the number of repetitions performed during the first set of repetitions on the second day of activity. The treatments used in Study I and Study II significantly …

Resilience Routing in AdHoc Networks. A decision based routing tree mechanism that can establish routes in adhoc network, which may than be configured into logical dual ring. Also a system is proposed to embed the QoS mechanisms, resilience and reliability features from RPR.
… resilience, and reliability features from RPR. The simulations were created using Microsoft Visual Studio.Net for the Decision based routing algorithm. The results were compared with an existing LAR algorithm. We have obtained 95% confidence intervals on all the performance analysis results …

Stroke in the young adults at the University Teaching Hospital, Lusaka
… and examination, investigation done included RPR, CT, RBS, ECG, ECHO, LP, FBC, U/E, CD4 and LFT. A matched control group of thirty patients was also recruited.The results showed 25 (83.3%) of stroke patients were positive for HIV while the seroprevalence in the control group was (53.3%). The …

Bcl-2 Function in Drosophila
… dark, but was not required for killing by RPR proteins. Surprisingly, in a model of caspaseindependent cell death, we found that heterologous killing by Murine Bax required debcl to exert its pro-apoptotic activity. DebclKO mutants were also significantly affected for mitochondrial density. …
