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...

Ca2+-induced Ca2+ release (CICR) from the sarcoplasmic reticulum (SR) via ryanodine receptors (RyRs) ultimately governs cardiac muscle force and can be considered as an amplification system for cardiac Ca2+ signals. CICR is initiated by Ca2+ influx via voltagedependent L-type Ca2+ channels. Unlike skeletal muscle fibres, each cardiac myocyte can produce an amount of force (and a Ca2+ transient)...

Idle speed control remains one of the most challenging problems in the automotive control eld owing to its multiple-input, multiple-output structure and the step nature of the disturbances applied. In this paper a simulation model is described for a 4.0 l production engine at idle which includes the standard bypass air valve and spark advance dynamics, as well as the e ects of operating point o...

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...
