Abstract:
A torque transmission for a gas turbine rotor includes a plurality of adjacent rotating machine wheels. Each wheel includes a first flange on a first axial side and a second flange on a second axial side. The first flange has a plurality of first teeth extending around the circumference of the first flange and spaced by first slots, and the second flange has a plurality of second teeth extending around a circumference of the second flange and spaced by second slots. The first teeth of a first wheel are received in the second slots of a second, adjacent wheel to transmit torque through shear of the teeth and the first flange and the second flange are engaged to transmit torque through friction between the flanges.
Abstract:
Disclosed are compositions comprising antioxidants and stabilizers, such as, acid scavengers or organic phosphorus stabilizers, and optionally further comprising co-stabilizers. The disclosed compositions are useful as stabilizers for polyolefins and other polymeric materials. The disclosed compositions and methods generally provide longer shelf lives and better oxidative resistance to materials than currently available antioxidants.
Abstract:
Systems and methods for real-time viewing and manipulation of information hosted on third-party systems are described. The system and methods enable property managers to create, edit and delete real estate vacancy postings on multiple sites from a single account, view metrics associated with the postings, and shift the administrative burdens associated with the unreliability of third-party systems to the system itself.
Abstract:
A silicon carbide (SiC) substrate is provided with an off-oriented {0001} surface whose off-axis direction is . A trench is formed on the SiC to have a stripe structure extending toward a direction. An SiC epitaxial layer is formed on an inside surface of the trench.
Abstract:
A system and method for quantifying clinical skill of a user, comprising: collecting data relating to a surgical task done by a user using a surgical device; comparing the data for the surgical task to other data for another similar surgical task; quantifying the clinical skill of the user based on the comparing of the data for the surgical task to the other data for the other similar surgical task; outputting the clinical skill of the user.
Abstract:
The present invention provides polynucleotides encoding clot-specific streptokinase proteins possessing altered plasminogen characteristics, including enhanced fibrin selectivity. The kinetics of plasminogen activation by these proteins are distinct from those of natural streptokinase, in that there is a temporary delay or lag in the initial rate of catalytic conversion of plasminogen to plasmin. Also disclosed are processes for preparing the proteins.

Abstract:
Power switch units for microelectronic devices are disclosed. In one aspect, a microelectronic device may include a functional circuit, and a power switch unit to switch power to the functional circuit on and off. The power switch unit may include a large number of transistors coupled together. The transistors may include predominantly positive-channel, insulated gate field effect transistors, which have a gate dielectric that includes a high dielectric constant material. Power switch units having such transistors may tend to have low power consumption. In an aspect, an overdrive voltage may be applied to the gates of such transistors to further reduce power consumption. Methods of overdriving such transistors and systems including such power switch units are also disclosed.
Abstract:
A polymer is characterized by a repeat unit represented by Structural Formula (I), or a copolymer thereof. A crosslinked polymer characterized by a repeat unit represented by Structural Formula (II), (III), (IV) or (V), or a copolymer thereof, wherein at least one such repeat unit of a first polymer strand is crosslinked with at least one repeat unit of a second polymer strand by at least one bridging unit, the first and second polymer strands and the repeat unit being components of the crosslinked polymer.
