Various embodiments relate to systems and/or methods for sample preparation that can be used for biochemical and/or molecular biology procedures involving small volumes, for example, micro volumes or smaller. Methods and systems that can reduce sample size requirements and increase the number of samples on a substrate are provided. Samples can be applied to a plate or other appropriate substrate and can be used for, inter alia, sequencing reactions. In some embodiments, apparatuses, systems, and/or methods for charged analyte collection are provided. Charged analytes in a sample can be electrokinetically collected or extracted from a conduit through a hole formed in a sidewall of the conduit, by application of an electric field that causes the charged analytes to migrate in a direction that is transverse to the conduit.
摘要:
Various embodiments described in the application relate to an apparatus, system, and method for generating, within a conduit, discrete volumes of one or more fluids that are immiscible with a second fluid. The discrete volumes can be used for biochemical or molecular biology procedures involving small volumes, for example, microliter-sized volumes, nanoliter-sized volumes, or smaller. The system can comprise an apparatus comprising at least one conduit operatively connected to one or more pumps for providing discrete volumes separated from one another by a fluid that is immiscible with the fluid(s) of the discrete volumes, for example, aqueous immiscible-fluid-discrete volumes separated by an oil.

Various embodiments described in the application relate to an apparatus, system, and method for fluidically controlling, within a conduit, discrete volumes of one or more fluids that are immiscible with a second fluid. The discrete volumes can be used for biochemical or molecular biology procedures involving small volumes, for example, microliter-sized volumes, nanoliter-sized volumes, or smaller. The system can comprise combinations of detectors, controllers, valves, and fluid supply units to control the spatial size, location and/or fluidic composition of discrete volumes separated from one another by a fluid that is immiscible with the fluid(s) of the discrete volumes, for example, aqueous immiscible-fluid-discrete volumes separated by an oil.

摘要:
A fastener for fastening pipes or electrical conduit can be installed with the optional use of nails or screws. The fastener includes sharp teeth or spikes which can be hammered into an external surface, such as wood or masonry. The teeth or spikes are positioned, oriented, and otherwise configured to best suit the intended application. Installation can be accomplished using only the fastener itself and force exceeding a minimal threshold.
摘要:
In various embodiments, training objects are classified by human annotators, psychometric data characterizing the annotation of the training objects is acquired, a human-weighted loss function based at least in part on the classification data and the psychometric data is computationally derived, and one or more features of a query object are computationally classified based at least its part on the human-weighted loss function.
摘要:
Systems and methods for reactively authorizing publication of information by a third party are coordinated through the use of a presence server. The presence server communicates with other communication nodes/devices to determine and relay publication information. Publication requests that are initially unauthorized, from the perspective of the presence server, are resolved.
摘要:
Locating devices and systems providing haptic tactile feedback are disclosed. In one embodiment, a locator includes a haptic handle configured to provide directional signals through an operator's sense of touch to aid in locating and tracing a buried conductor or other object such as a pipe or cable.
