The properties of Ca(2+) sparks in frog intact skeletal muscle fibers depolarized with 13 mM [K(+)] Ringer's are well described by a computational model with a Ca(2+) source flux of amplitude 2.5 pA (units of current) and duration 4.6 ms (18 degrees C; Model 2 of Baylor et al., 2002). This result, in combination with the values of single-channel Ca(2+) current reported for ryanodine receptors (...

BigBench is the new standard (TPCx-BB) for benchmarking and testing Big Data systems. The TPCx-BB specification describes several business use cases —queries— which require a broad combination of data extraction techniques including SQL, Map/Reduce (M/R), user code (UDF), and Machine Learning to fulfill them. However, currently, there is no widespread knowledge of the different resource require...

The effects of spark timing and exhaust valve timing change on exhaust gas temperature during cold start of an SI engine are studied through engine bench tests. It is observed that the exhaust gas temperature increases when the spark timing and valve timing are retarded individually or simultaneously, due to late combustion or slow flame speed. However, using COVimep it is also investigated tha...

As a parallel computation framework, Spark can cache repeatedly resilient distribution datasets (RDDs) partitions in different nodes to speed up the process of computation. However, Spark does not have a good mechanism to select reasonable RDDs to cache their partitions in limited memory. In this paper, we propose a novel selection algorithm, by which Spark can automatically select the RDDs to ...

By examining the two papers on 4G and 3G, namely wireless networks: opportunities and challenges by Hassan Gobjuka, Verizon, 919 hidden bridge irving, Tx 75038 and wireless network: opportunities and challenges emphasis us to throw light on the differences between the two networks. This task is being done in order to list out the drawbacks and merits of these two evolutions of the networks and ...

OBJECTIVE As child maltreatment has a major impact, prevention and early detection of parenting problems are of great importance. We have developed a structured interview which uses parents' concerns for a joint needs assessment by parents and a child health care nurse, followed by a professional judgment on the risk level of future parenting and developmental problems: the Structured Problem A...

Ca(2+) sparks are highly localized cytosolic Ca(2+) transients caused by a release of Ca(2+) from the sarcoplasmic reticulum via ryanodine receptors (RyRs); they are the elementary events underlying global changes in Ca(2+) in skeletal and cardiac muscle. In smooth muscle and some neurons, Ca(2+) sparks activate large conductance Ca(2+)-activated K(+) channels (BK channels) in the spark microdo...

Several perspectives on Ca 2 1 sparks were recently published. A common theme was the importance of defining the mechanisms that terminate local SR Ca 2 1 release. We propose that the timeand Ca 2 1 -dependent modal gating behavior of single ryanodine receptor (RyR) channels is the negative control mechanism that terminates local Ca 2 1 release. Specifically, the observed “inactivation” and “ad...

The web is transforming from traditional web to web of data, where information is presented in such a way that it is readable by machines as well as human. As a part of this transformation, every day more and more websites implant structured data, e.g. product, person, organization, place etc., into the HTML pages. To implant the structured data different encoding vocabularies, such as RDFa, mi...
