The arterial baroreflex buffers slow (<0.05 Hz) blood pressure (BP) fluctuations, mainly by controlling peripheral resistance. Baroreflex sensitivity (BRS), an important characteristic of baroreflex control, is often noninvasively assessed by relating heart rate (HR) fluctuations to BP fluctuations; more specifically, spectral BRS assessment techniques focus on the BP-to-HR transfer function ar...

conclusions this was the first study that focused on expanding resilience indicators, and presents a new framework to simplify assessment of resilience and safety of a complex system. results in this study, 29 factors affecting this indicator were determined using the delphi method; the scores of all factors were less than the scores of the best practice. on the other hand, the state of this in...

A video streaming application needs to employ a transport layer protocol to transmit packetized media data. Since TCP is the most dominant protocol over the Internet, it is reasonable to consider TCP for video streaming. However, the AIMD behavior and retransmission timeouts of TCP may introduce unacceptable end-to-end delay, and therefore it is difficult to provide good quality of streaming vi...

Increased calcium buffering in basal forebrain neurons during aging. J. Neurophysiol. 80: 350-364, 1998. Alterations of neuronal calcium (Ca2+) homeostasis are thought to underlie many age-related changes in the nervous system. Basal forebrain neurons are susceptible to changes associated with aging and to related dysfunctions such as Alzheimer's disease. It recently was shown that neurons from...

In our previous paper, we have proposed a framework for automatically translating tree-processing programs into stream-processing programs. However, in writing programs that require buffering of input data, a user has to explicitly use buffering primitives which copy data from input stream to memory or copy constructed trees from memory to an output stream. Such explicit insertion of buffering ...

A supramolecular system in which the concentration of a molecule is buffered over several orders of magnitude is presented. Molecular buffering is achieved as a result of competition in a ring-chain equilibrium of multivalent ureidopyrimidinone monomers and a monovalent naphthyridine molecule which acts as an end-capper. While we previously only considered divalent ureidopyrimidinone monomers w...
