    摘要： A system and process for chromatography that uses a chromatography column to separate components from a sample received into the column in a mobile phase flowstream and places a second chromatography column between a detector and a collection system that compensates the timing of fraction collection for a delay caused by processing the collection signals generated by the detector. The device and process of the preferred and alternative embodiments add a delay into the flowstream of a chromatographic system, such as LC, HPLC, and SFC. Sample fractions are collected from sample component concentration peaks based upon the chromatographic elution of the sample components.

    摘要： A request to resolve an IP address is received by a Domain Name Server (DNS). A record, such as an MX record, relating to the request is obtained that comprises a unique label (e.g. record=customer-com.mail.messaging.com) that is used in determining how to resolve the request. The unique label portion of the record (e.g. customer-com) is used to identify information relating to the request such as a version of software/service to use to handle the request, a region used to handle the request, and the like. The same record may be used to direct a request to a different version and/or different region. For example, without changing the record, a request at one time may access a first version/region and a request at a different time access a different version/region.

    摘要： A photo ionization detector (PID) is provided for selectively determining various compounds or gases present in a breath sample. The PID, comprises a substrate comprising a gas ionization chamber, at least one pair of ion sensing electrodes, and at least one amplifying circuit; and an ultraviolet (UV) ionization source to transmit a UV light beam into the gas ionization chamber. A system comprises the PID is also provided. A method of detecting a response pattern for various compounds or gases in breath using PID is also provided.

    摘要： A centralized account reputation system differentiates between illegitimate users and legitimate users using reputation scores associated with the users' online accounts. The system restricts the access of illegitimate users to certain network services while minimizing its negative effects on legitimate users. The system can manage the life cycle of an online account, considering data about the account that is obtained throughout the account network to compute the online account reputation score and allocating access to network services based on the online account reputation score. For example, a reputation score may be embedded in a security token that can be accessed by multiple services on the account network, so that each service can determine the appropriate level of access to be granted to the associated user account based on the reputation score. Various types of online account behavior over time can improve or diminish the online account's reputation.

    摘要翻译： 集中帐户信誉系统区分非法用户和合法用户使用与用户在线账户相关联的信誉评分。 该系统限制非法用户访问某些网络服务，同时最大限度地减少其对合法用户的负面影响。 系统可以管理在线帐户的生命周期，考虑在整个帐户网络中获得的帐户的数据，以计算在线帐户信誉分数，并根据在线帐户信誉评分分配对网络服务的访问。 例如，信誉分数可以嵌入在可由帐户网络上的多个服务访问的安全令牌中，使得每个服务可以基于信誉分数来确定被授予相关联的用户帐户的适当的访问级别。 随着时间的推移，各种类型的在线帐户行为可以改善或减少在线帐户的声誉。
