Abstract: Methods, systems and devices that provide fluid devices with at least one SPE bed adjacent (upstream of) a separation channel which may be in communication with an inlet of a Mass Spectrometer. The fluid device can be configured to operate using independently applied pressures to a BGE reservoir and a sample reservoir for pressure-driven injection that can inject a discrete sample plug into a separation channel that does not require voltage applied to the sample reservoir and can allow for in-channel focusing methods to be used. The methods, systems and devices are particularly suitable for use with a mass spectrometer but optical or other electronic detectors may also be used with the fluidic devices.

Abstract: Devices and methods generate an ordered restriction map of genomic DNA extracted from whole cells. The devices have a fluidic microchannel that merges into a reaction nanochannel that merges into a detection nanochannel at an interface where the nanochannel diameter decreases in size by between 50% to 99%. Intact molecules of DNA are transported to the reaction nanochannel and then fragmented in the reaction nanochannel using restriction endonuclease enzymes. The reaction nanochannel is sized and configured so that the fragments stay in an original order until they are injected into the detection nanochannel. Signal at one or more locations along the detection nanochannel is detected to map fragments in the order they occur along a long DNA molecule.

The reagent is attached to the solid support via a labile reagent/support bond such that the reagent is configured to be cleaved from the support via a cleaving operation.

Abstract: An electrospray ionization (ESI)-mass spectrometer analysis systems include an ESI device with at least one emitter configured to electrospray ions and a mass spectrometer in fluid communication with the at least one emitter of the ESI device. The mass spectrometer includes a mass analyzer held in a vacuum chamber. The vacuum chamber is configured to have a high (background/gas) pressure of about 50 mTorr or greater during operation. During operation, the ESI device is configured to either; (a) electrospray ions into a spatial region external to the vacuum chamber and at atmospheric pressure, the spatial extent being adjacent to an inlet device attached to the vacuum chamber, the inlet device intakes the electrosprayed ions external to the vacuum chamber with the mass analyzer and discharges the ions into the vacuum chamber with the mass analyzer; or (b) electrospray ions directly into the vacuum chamber with the mass analyzer.

Abstract: Techniques for providing feed-based case management on an online social network. A user interface that includes a publisher and an information feed is provided. Information associated with a record is received and the record is updated in a database system. A feed item associated with the database system update is generated and provided in the information feed. The feed item includes one or more actionable selections providing a reference to the publisher. Selection of one of the one or more actionable selections causes the publisher to be operable to receive further information associated with the record. The record is capable of being updated based on the further information. In some implementations, the record is a case and the user interface serves as a single interface for all interactions required in solving the case.

Abstract: Methods, systems and devices that generate differential axial transport in a fluidic device having at least one fluidic sample separation flow channel and at least one ESI emitter in communication with the at least one sample separation flow channel. In response to the generated differential axial transport, the at least one target analyte contained in a sample reservoir in communication with the sample separation channel is selectively transported to the at least one ESI emitter while inhibiting transport of contaminant materials contained in the sample reservoir toward the at least one ESI emitter thereby preferentially directing analyte molecules out of the at least one ESI emitter. The methods, systems and devices are particularly suitable for use with a mass spectrometer.

Abstract: Systems and methods are provided for dynamic list views and detail pages. A database system can update a subscribed field in a data record when the field is updated and when a user interface is displaying the field in a list view. The system can provide a notification of an update for a subscribed field in a data record when the field is updated and when a user interface is displaying the field in a list view.

Abstract: An information handling system is set forth which includes a fully connected 4S topology that can also be populated with two processors and two link modules (e.g., two passive “slugs”) to implement a fully connected 2S topology. More specifically, the link module is a printed circuit board that implements a loopback connection between certain links of the architecture. In certain embodiment, the link module includes no electrical components. The link module merely includes a set of electrical connections (e.g., copper traces) connecting pads (e.g., gold plated pads) on a thick printed circuit board (PCB) dielectric material that is shaped to fit the processor socket. The link module is used to carry user data when the information handling system is configured in a 2S topology. The link module includes proper lane assignment that allows the module to be passive without performance reduction.
