  • Publication number: 20150161725
    Abstract: According to some embodiments, a system includes an interface and one or more processors. The interface receives a request from a user to move a first account associated with a first enterprise to a second enterprise where the user has at least one account. The processor(s) determine first configuration settings associated with the first account. The processor(s) receive a modification request to modify or delete one or more of the first configuration settings and select second configuration settings associated with the second account based on the first configuration settings and the modification request. The processor(s) create a second account at the second enterprise and apply the second configuration settings to the second account.

  • Publication number: 20150111644
    Abstract: A ranking system is provided. The ranking system may provide a qualitative method of ranking quantitative evaluation data of players from a plurality of player pools, wherein the plurality of player pools are a subset of the entire group of potential players. The ranking system may provide a method of transforming a plurality of two types—objective and subjective—of evaluation data for a plurality of players into a ranking for each player by standardizing both types on the same on a common scale and applying weights to prioritize specific evaluation and, separately, applying weights to indicate the relative importance between the two types—objective and subjective—of evaluation data, so as to meet the needs of a predetermined team.

  • Patent number: 8329422
    Abstract: The methods and reagents described in this invention are used to analyze circulating tumor cells, clusters, fragments, and debris. Analysis is performed with a number of platforms, including flow cytometry and the CELLSPOTTER® fluorescent microscopy imaging system. Analyzing damaged cells has shown to be important. However, there are two sources of damage: in vivo and in vitro. Damage in vivo occurs by apoptosis, necrosis, or immune response. Damage in vitro occurs during sample acquisition, handling, transport, processing, or analysis. It is therefore desirable to confine, reduce, eliminate, or at least qualify in vitro damage to prevent it from interfering in analysis. Described herein are methods to diagnose, monitor, and screen disease based on circulating rare cells, including malignancy as determined by CTC, clusters, fragments, and debris. Also provided are kits for assaying biological specimens using these methods.
