    摘要: A process for purification of water soluble polymers is provided. A polymer of interest can be separated from a mixture of polymers, provided the polymer of interest differs from other polymers in the mixture in the number of reactive terminal groups. The process involves derivatizing polymers at the reactive terminal groups with a derivatizing molecule, bearing either (i) two or three cationic or anionic ionizable groups, and a group capable of covalent bonding to the reactive terminal groups or (ii) three or four ionizable groups, at least one of which is capable of covalent bonding to the reactive terminal groups; followed by ion exchange. The process allows removal of PEG from MPEG, and can be used for polymers having an average size greater than 9,000 Da Derivatization may be reversible in order to allow re-use of recovered contaminant polymers.

    摘要: Disclosed embodiments include a system and a method for determining intracranial pressure (ICP) of a subject that comprises: (a) applying transcranial Doppler (TCD) to determine the middle cerebral artery (MCA) velocity of the subject and estimating changes in the ICP continuously based on a functional mapping that relates arterial blood pressure (ABP) and cerebral blood flow velocity (CBFV) to ICP, resulting in an estimated ICP trend; (b) generating a flash visual evoked potential (FVEP) on the subject, processing a detected FVEP signal and obtaining an estimated ICP; and (c) combining the estimated ICP trend from TCD CBFV and ABP with the estimated ICP obtained by signal processing of the detected FVEP signal to periodically correct the trend and obtain a non-invasive measure of ICP.

    摘要: Systems and methods for supporting a liquid against a vacuum pressure in a chamber can enable analysis of the liquid surface using vacuum-based chemical analysis instruments. No electrical or fluid connections are required to pass through the chamber walls. The systems can include a reservoir, a pump, and a liquid flow path. The reservoir contains a liquid-phase sample. The pump drives flow of the sample from the reservoir, through the liquid flow path, and back to the reservoir. The flow of the sample is not substantially driven by a differential between pressures inside and outside of the liquid flow path.An aperture in the liquid flow path exposes a stable portion of the liquid-phase sample to the vacuum pressure within the chamber. The radius, or size, of the aperture is less than or equal to a critical value required to support a meniscus of the liquid-phase sample by surface tension.

    摘要: Embodiments include a computer system that receives registration information from a service provider registering web services with the dynamic web service configuration store, where the registration information indicates a mapping of which web service components are to be used with corresponding user requests. The computer system receives a request from a user requesting a portion of web service functionality and provides the web service functionality using the web service component indicated in the mapping. The computer system receives an indication from the service provider that various web service components are to be updated, where the indication includes updated web service component portions. The computer system also dynamically updates the web service component, so that subsequent user requests for the same portion of web service functionality are processed using the updated web service component.
