A microfluidic manipulation system is provided that includes a blade for manipulating deformable material and at least one movable support that is capable of moving the blade into contact with a microfluidic device including a deformable feature. When the microfluidic device is operatively held by a holder, a movable support can position the distal end of the blade relative to the microfluidic device and move the contact tip surface of the blade such that it deforms the deformable feature.

Apparatus, methods and computer program products are disclosed that enable a compiler to generate efficient code to access stack registers on a register stack. The invention operates by transforming a three-operand instruction, within a compiler's intermediate representation, to one or more fewer-than-three-operand instructions. The invention also transforms the instruction's operand addressing from an access to a pseudo-named register to an access to a stack register through stack offset into a register stack. The invention also determines the register stack state at each instruction responsive to register stack permutations and maps the stack offset accordingly for each subsequent access to a stack register.

On a tightly coupled multiprocessor computer system, the multiple parallel regions of a multithreaded applications program can execute simultaneously as multiple threads on a plurality of processors. Furthermore, a plurality of multithreaded programs may run simultaneously. The current invention uses an efficient system to schedule and reschedule processors to run these multiple threads. Scheduling is integrated at two levels: at the first level, processors are assigned processes. At the next level, processes are assigned threads. Increased efficiency is achieved by this integration and also by the formation of processes with destructible context. It makes use of shared storage to indicate the process request level and the control state for each parallel region.

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.
