A flexible IC/microfluidic hybrid integration and packaging method and resulting device. A single flexible elastomer substrate, such as polydimethylsiloxane (PDMS), has dedicated microchannels filled with liquid metals (or low melting point solders) to provide electrical interconnects to a solid-state IC die, such as CMOS, and additional microchannels for hybrid integration with microfluidics without performing any post-processing on the IC die. The liquid metal used can be a gallium-indium-tin eutectic alloy (also called Galinstan).

A fuel injector configured to inject a predetermined volume of fuel, such as heavy fuel oil, is disclosed. The disclosed injector includes an injector body that defines a fuel inlet, a fuel passageway, and an orifice. The injector also includes a needle disclosed at least partially within the injector body. The needle is movable between a closed position where the needle blocks the orifice and an open position where the needle at least partially unblocks the orifice. At least the injector body and the needle define a nozzle chamber. The nozzle chamber is in communication with a high pressure fuel passageway and the orifice. The fuel passageway and nozzle chamber have a combined volume greater than the predetermined injection volume. The combined volume of the nozzle chamber and fuel passageway act as a damper to alleviate the effects of pressure overshoot, pressure oscillations and water hammer

The invention relates to a microfluidic dye laser including a pump light source configured to provide light having a pump light wavelength. The microfluidic dye laser also includes an elastomer substantially optically transparent at the pump light wavelength and at a microfluidic dye laser wavelength. A microfluidic channel configured to accept a fluidic dye is defined in the elastomer. An optical grating is formed in a single mode 3D waveguide in the microfluidic channel in order to provide a single mode microfluidic dye laser light as output in response to illumination with light from the pump light source. In another aspect, the invention features a method of tuning a wavelength of a microfluidic dye laser light by mechanically deforming the elastomeric laser chip to change the grating period in the optical cavity.

A handheld system includes a reference pressure source configured to generate a reference pressure. The handheld system also includes a primary pressure source coupled to the reference pressure source. The primary pressure source is configured to generate a primary pressure in a primary pressure range. The primary pressure is less than the reference pressure, and the primary pressure is induced by the reference pressure source. The handheld system also includes a secondary pressure source coupled to the primary pressure source. The secondary pressure source is configured to generate a secondary pressure in a secondary pressure range. The secondary pressure is less than the primary pressure, and the secondary pressure is induced by the primary pressure source.

Provided is a method of gap closing in nucleotide sequence. The nucleic acid sequence comprises a first contig at one end of a gap in an unassembled region, and a second contig at the other end of the gap in the unassembled region. The method comprises: selecting reads having an overlap with one end of the first contig close to the gap as a set of reads for gap closing; selecting reads having a shortest overlap with the first contig in the set of reads for gap closing as a candidate read; determining whether reads having an overlapping length with the first contig shorter than an overlapping length between the candidate read and the first contig present in the set of reads for gap closing, and determining whether reads having no overlapping relationship with the candidate read present in the set of reads for gap closing; obtaining a result of presenting an extension conflict, and determining an unconfident candidate read, if reads having an overlapping length with the first contig shorter than an overlapping length between the candidate read and the first contig present in the set of reads for gap closing, reads having no overlapping relationship with the candidate read present in the set of reads for gap closing, or both reads having an overlapping length with the first contig shorter than an overlapping length between the candidate read and the first contig, and reads having no overlapping relationship with the candidate read present in the set of reads for gap closing; reselecting the candidate read until obtaining a confident candidate read, if the candidate read is unconfident; connecting the confident candidate read to the first contig, to form a new first contig; determining whether one end of the new first contig close to the gap has an overlap with one end of the second contig close to the gap; performing the step of selecting the set of reads for gap closing on the basis of the new first contig, if the one end of the new first contig close to the gap has no overlap with the one end of the second contig close to the gap, wherein the first contig in the step of selecting the set of reads for gap closing is replaced with the new first contig; connecting the new first contig to the second contig to complete gap closing, if one end of the new first contig close to the gap has an overlap with one end of the second contig close to the gap.

A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber an E orifice and a buffer chamber, which may assist in avoiding cavitation erosion in a sensitive area associated with a flat control valve seat. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.
