Ultrasonic device for cutting and coagulating

An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The assembly includes a clamping mechanism, including a clamp arm cam-mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces. The balanced blade provides a functional asymmetry for improved visibility at the blade tip and a multitude of edges and surfaces, designed to provide a multitude of tissue effects: clamped coagulation, clamped cutting, grasping, back-cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural axial motion of the user's index or middle fingers, whether gripping the surgical instrument right-handed or left handed.

Device for cutting glass substrate and its method

An apparatus for cutting a nonmetallic substrate (P) and method thereof are disclosed. The present invention is suitable for cutting upper and lower substrates (P) simultaneously or for cutting either an upper or lower substrate selectively in a manner of controlling a cutting depth by adjusting a focus position of a short wavelength laser beam in cutting various nonmetallic substrates (P) such as a glass substrate for fabricating a flat panel display such as TFT-LCD, PDP, OLED, etc. The present invention includes a laser beam generator (10) generating a UV short wavelength laser beam, a torch (6) applying the short wavelength laser beam to a specific location on the nonmetallic substrate to be cut, a focus moving means (8) for varying a focus location of the laser beam in a depth direction of the substrate, and a relative object moving means (3, 4) for allowing the substrate and the laser beam to make a relative movement to cut the substrate.

Primers useful for sizing nucleic acids

InactiveUS6949633B1Amount of new and usefulNew and useful and size informationSugar derivativesMicrobiological testing/measurementOligonucleotide primersBase pair
The present invention provides modified oligonucleotide primers designed to incorporate a cleavable moiety so that a 3′ portion of the primer (linked to an extension product) can be released from an upstream 5′ portion of the primer. Upon selective cleavage of the cleavable site, primer extension products that contain about five or fewer base pairs of the primer sequence are released, to provide more useful sizing and sequence information per fragment than extension products containing the entire primer.

Rebinning methods and arrangements for use in compressing image-based rendering (IBR) data

Rebinning methods and arrangements are provided that significantly improve the 3D wavelet compression performance of the image based rendering data, such as, e.g., concentric mosaic image data. Through what is essentially a selective cutting and pasting process the image data is divided into stripes that are then used to form a set of multi-perspective panoramas. The rebinning process greatly improves the performance of the cross shot filtering, and thus improves the transform and coding efficiency of 3D wavelet codecs. While the region of support after rebinning may cease to be rectangular in some cases, a padding scheme and an arbitrary shape wavelet coder can be implemented to encode the result data volume of the smart rebinning. With an arbitrary shape wavelet codec, the rebinning outperforms MPEG-2 by 3.7 dB, outperforms direct 3D wavelet coder by 4.3 dB, and outperforms a reference block coder (RBC) by 3.2 dB on certain tested concentric mosaic image scenes. Hence, the rebinning process nearly quadruples the compression ratio for selected scenes. Additional methods and arrangements are provided that include selectively dividing the image data into slits and rebinning the slits into a huge 2D array, which is then compressed using conventional still image codecs, such as, JPEG.

Carbon sequestration via wood burial and storage

To mitigate global climate change, a portfolio of strategies will be needed to keep the atmospheric CO2 concentration below a dangerous level. Here a carbon sequestration strategy is proposed in which certain dead or live trees are harvested via collection or selective cutting, then buried in trenches or stowed away in above-ground shelters. The largely anaerobic condition under a sufficiently thick layer of soil will prevent the decomposition of the buried wood. Because a large flux of CO2 is constantly being assimilated into the world's forests via photosynthesis, cutting off its return pathway to the atmosphere forms an effective carbon sink.

Disruptors of early/recycling endosomes

A delivery system for introducing a cargo molecule into cytosol of a living cell can include: a first membrane binding element linked to an endosomal compartment disrupting element through a first linker having one or more anionic moieties; and a second membrane binding element linked to an exogenous cargo molecule through a second linker having one or more anionic moieties, the second linker having a region that is selectively cleavable, wherein the first and second membrane binding elements both induce endocytosis into an early / recycling endosome and the endosomal compartment disrupting element destabilizes the early / recycling endosome such that the exogenous cargo molecule is released from the second membrane binding element and into the cytosol of the living cell.

Metal-organic framework catalysts for selective cleavage of aryl-ether bonds

The present invention relates to methods of employing a metal-organic framework (MOF) as a catalyst for cleaving chemical bonds. In particular instances, the MOF results in selective bond cleavage that results in hydrogenolyzis. Furthermore, the MOF catalyst can be reused in multiple cycles. Such MOF-based catalysts can be useful, e.g., to convert biomass components.
