A system for developing and implementing empirically derived algorithms to generate decision rules to predict subject noncompliance and fraud with research protocols in clinical trials allows for the identification of complex patterns of variables that detect or predict subject noncompliance and fraud with research protocol in the clinical trial. The present invention can also be used to monitor subject compliance with the research protocol to determine preferred actions to be performed. Optionally, the invention may provide a spectrum of noncompliance, from minor noncompliance needing only corrective feedback, to significant noncompliance requiring subject removal from the clinical trial. The algorithms and decision rules can also be domain-specific, such as detecting non-compliance or fraud among subjects in a cardiovascular drug trial, or demographically specific, such as taking into account gender or age which provides for algorithms and decision rules to be optimized for the specific sample of subjects being studied.

The present invention relates to a method and an apparatus for simultaneously assessing the functional status of component parts of the nervous system by presenting sparse stimuli to one or more parts of the sensory nervous system. Sparse stimuli consist of temporal sequences of stimulus conditions presented against a baseline null stimulus condition, where the non-null stimulus condition, or conditions, are presented relatively infrequently. The low probability of encountering a stimulus differing from a baseline or null stimulus condition in sparse stimulus sequences insures that gain control mechanisms within the nervous system will increase the neural response magnitude and also bias the measured responses to those neurone populations having such gain controls. The consequently increased response amplitudes ensure more reliably recorded responses than are obtained with non-sparse stimuli.

The invention discloses an accelerator X-ray dosage monitoring device in an X-ray radiation imaging system. The X-ray radiation imaging system comprises an accelerator X-ray source, a collimator for collimating X rays and a detection probe. The X-ray dosage monitoring device comprises an X-ray dosage monitoring probe, wherein X-ray dosage measured by the detection probe is corrected according to the X-ray radiation dosage monitored by the X-ray dosage monitoring probe. The X-ray dosage monitoring probe is arranged on at lease one side of a collimating slit of the collimator and is used for monitoring the dosage of the X rays radiated from an accelerator; and by changing the positions of dosage monitoring points, the dosage monitoring probe is arranged on the collimator, the monitoring probe is close to an accelerator target spot and the dosage rate of the accelerator received by the monitoring probe is high, so that data has high statistic properties. Simultaneously normal beams are not blocked, so the statistic properties of probe data of the detection probe are not reduced.

The invention relates to a system, a method and an apparatus for performing statistics on loading performance information of a page, and belongs to the field of data statistics. The method comprises the steps of obtaining loading time information when a terminal loads a specified page; sending the loading time information to a server; performing statistics on the loading time information sent by at least one terminal including the terminal by the server; and obtaining loading the loading performance information of the specified page. According to the scheme, a statistical result can indicate duration information of each stage in the whole page loading process, so that statistical information is richer, the problem of relatively single statistical information due to operation of performing statistics on only the total consumed time from the time of starting the loading of the page to the time of ending the loading of the page each time in the prior art is solved, and the purpose of improving the statistics effect of the loading performance information of the page is achieved.

The invention discloses an apparatus and method for realizing message statistics. The apparatus comprises an exchange module and a statistic information processing module. The exchange module is used for receiving a data stream message, carrying out parsing on the received data stream message to obtain statistic information, assembling the obtained statistic information into a statistic message, and sending the statistic message to the statistic information processing module.

The invention provides a method and device for improving the SSR violation-log statistical performance, and belongs to the technical field of computer safety. According to the method, violation-log data is written and stored based on a MongoDB database, and when violation-log statistics of SSR is carried out, the statistical performance is improved through a viewpoint of caching statistical results; when the statistical results are cached, segment caching is carried out according to the statistical results of different time interval lengths, and then according to query time periods set by a user, the cached statistical results of corresponding time periods are shown. When segment caching is carried out, uploaded violation logs or caching of the statistical results is counted according to the real time, the hour and the day respectively. According to the method and device, when a large quantity of violation logs are generated in the SSR, the statistical performance is improved, and userexperiences are improved.

The current invention relates to new tools and methods enabling neuroblastoma patient stratification into prognostic favorable or unfavorable groups. The invention is based on the re-analysis of published gene expression data-sets studying neuroblastoma tumors generating different prognostic gene lists. The overlapping gene lists were subsequently tested for their prognostic power on both the published tumor samples and on an unseen large set of unpublished samples, greatly increasing the statistical power of prognostic analyses. In addition, expression analysis of miRNAs in neuroblastoma tumors with different prognosis was performed. By doing this, the inventors could establish a neuroblastoma prognostic classifier with highly improved prognostic power, which is independent from the tumor sample set used to establish it. This classifier and its related prognostic tools and methods are thus perfectly suitable for routine clinical assessment of neuroblastoma prognosis.
