A novel testing framework for location based services is introduced. In particular, the paper showcases a novel architecture for such a framework. The implementation of the framework illustrates both the functionality and the feasibility of the framework proposed.a.d the utility of the architecture. The new framework is evaluated through comparison to several other methodologies currently available for the testing of location-based.a.plications. A case study is presented in which the testing framework was applied to a typical mobile service tracking system. It is concluded that the proposed testing framework achieves the best coverage of the entire location based service testing problem of the currently available methodologies; being equipped to test the widest array of application attributes and.a.lowing for the automation of testing activities.

Neural Regeneration Research 2016年第1期11卷 66-68页

Traumatic injuries to the central nervous system,such as traumatic brain injury,spinal cord injury and stroke,have a high prevalence,enormous financial costs and lack clinical treatments that restore neurological function（Ma et al.,2014）These injuries trigger a series of secondary biochemical and cellular responses that ultimately lead to cellular d.a.h and themaintenance of an unsupportive extracellular matrix （ECM） for tissue regeneration （Silva et al., 2014）. Artificial ECM or scaf- folds represent a way to alter this unsupportive environment to improve the efficacy of stem cell therapies and enhance neural tissue regeneration （Figure 1）.

This paper reports the use of a specialized, mesoscale, numerical weather prediction （NWP） system and.a.satellite imaging and prediction system that were set up to support the CLAMS （Chesapeake Lighthouse and.a.rcraft Measurements for Satellites） field campaign during the summer of 2001. The primary objective of CLAMS was to validate satellite-based retrievals of aerosol properties and vertical profiles of the rad.a.ive flux, temperature and water vapor. Six research aircraft were deployed to make detailed coincident measurements of the atmosphere and ocean surface with the research satellites that orbited overhead. The mesoscale weather modeling system runs in real-time to provide high spatial and temporal resolution for forecasts that are delivered via the World Wide Web along with a variety of satellite imagery and satellite location predictions. This system is a multi-purpose modeling system capable of both data analysis/assimilation and multi-scale NWP ranging from cloud-scale to larger than regional scale. This is a three-dimensional, non-hydrostatic compressible model in a terrain-following coordinate. The model employs ad.a.ced numerical techniques and contains detailed interactive physical processes. The utility of the forecasting system is illustrated throughout the discussion on the impact of the surface-wind forecast on BRdF （Bidirectional Reflectance distribution Function） and the description of the cloud/moisture forecast versus the aircraft measurement.

A commonly accepted view of plant growth hormones is that their interaction with the cognate receptor protein is reversible, so that each hormone molecule can potentially interact multiple times with a receptor and so either amplify the hormone signal or maintain it over an extended period of time. The signal can be ＇cancelled＇ by degrading the hormone. Strigolactones present us with a potentially new paradigm. The receptor is a serine hydrolase-type protein which attacks the strigolactone resulting in covalent modi- fication of the receptor, while at the same time destroying the hormone. Strigolactone is apparently a one-use ＇dispos- able＇ hormone.

AIM： To investigate the role of endogenous pain modulatory mechanisms in the central sensitization implicated by the visceral hypersensitivity demonstrated in patients with irritable bowel syndrome （IBS）. dysfunction of modulatory mechanisms would be expected to also result in changes of somatic sensory function. METHOdS： Endogenous pain modulatory mechanisms were assessed using heterotopic stimulation and somatic and visceral sensory testing in IBS. Pain intensities （visual analogue scale, VAS 0-100） during suprathreshold rectal distension with a barostat, cold pressor stimulation of the foot and during both stimuli simultaneously （heterotopic stimulation） were recorded in 40 female patients with IBS and 20 female healthy controls. RESULTS： Rectal hypersensitivity （defined by 95% Cl of controls） was seen in 21 （53%）, somatic hypersensitivity in 22 （55%） and both rectal and somatic hypersensitivity in 14 of these IBS patients. Heterotopic stimulation decreased rectal pain intensity by 6 （-11 to -1） in controls, but increased rectal pain by 2 （-3 to ＋6） in all IBS patients （P 〈 0.05） and by 8 （-2 to ＋19） in IBS patients with somatic and visceral hypersensitivity （P 〈 0.02）. CONCLUSION： A majority of IBS patients had.a.normal endogenous pain modulation and somatic hypersensitivity as evidence of central sensitization.
