Selective Back-pressure in Switched Ethernet Lans
Although switched LANs are usually over-provisioned, their characteristics (short RTT, link speed mismatches) lead to increased burstiness, and thus to the occurrence of transient congestion. In order to fully utilize the potential of large switched LANs, a link layer back-pressure mechanism may be used to complement end-to-end flow control by handling the short term congestion. A simple such m...
متن کاملSpeciation Dynamics: Generating Selective Pressure Towards Diversity
Recent approaches in evolutionary robotics (ER) propose to generate behavioral diversity in order to evolve desired behaviors more easily. These approaches require the definition of a behavioral distance which often includes task-specific features and hence a priori knowledge. Alternative methods, that do not explicitly force selective pressure towards diversity (SPTD) but still generate it, ar...
متن کاملSelective Protective Potency of Yersinia pestis ΔnlpD Mutants
It has recently been shown that the NlpD lipoprotein is essential to Yersinia pestis virulence and that subcutaneous administration of the nlpD mutant could protect mice against bubonic and pneumonic plague better than the EV vaccine strain [PLoS One 2009. V. 4. № 9. e7023]. In this study, similar ΔnlpD mutants were generated on the basis of other Y. pestis parent strains, including strains fro...
متن کاملProtective effect of resveratrol against pressure overload-induced heart failure
Transverse aortic constriction (TAC)-induced pressure overload (PO) causes adverse cardiac remodeling and dysfunction that progresses to heart failure (HF). The purpose of this study was to determine whether the potent antioxidant, resveratrol, significantly attenuates PO-induced HF in wild-type mice. Male C57BL6 mice were subjected to either sham or TAC surgery. One group of TAC mice was given...
متن کاملCaveats of pressure control: lung non-protective ventilation.
Editor—Lung-protective ventilation (LPV), in which the tidal volume is restricted to 6 ml kg and the plateau pressure to ,30 cm H2O, is the accepted standard of care for patients with acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS). A growing body of evidence supports the implementation of LPV in patients with other forms of acute respiratory failure and even in patie...
