Abstract: A rotor blade for a rotary wing aircraft includes a leading edge and a trailing edge defining a chordwise direction. The leading edge defines a forward end of the rotor blade and the trailing edge defines an aft end of the rotor blade. The rotor blade has a center of gravity and an aerodynamic center along the chordwise direction. The center of gravity is aft of the aerodynamic center.

Abstract: This application relates to a technique that enables efficient indexing and querying of a set of documents stored at a computing device. The technique assigns a rank to each term of a set of terms based on a historical occurrence of each term to produce a set of ranked terms. The technique also creates subsets that include terms from the set of ranked terms to produce ranked term subsets that are encoded in accordance with an allocated bit size. The technique generates an index for each document of the set of documents through: (1) the identification of the ranked term subsets within the document, (2) the generation of arrays to store each ranked term subset identified within the document, and (3) the embedding of metadata within the document. The metadata includes: (i) one or more arrays and (ii) one or more counts corresponding to each array.

Abstract: An improved pivot pin for a firearm may provide a head, shank, and/or openings. The improved pivot pin may also provide a modified central channel, an installation point, and/or installation channel to allow for tool-free or tool-less installation. Further, the improved pivot pin may provide a removal channel to allow the pivot pin to easily be removed from the lower receiver without tools. An improved takedown pin for a firearm may provide a head, shank, and/or openings. The improved takedown pin may also provide a modified center channel and/or removal channel as well. A removal tool to aid removal of a pivot pin or takedown pin from a firearm may be generally shaped to conform or fit within the channel of the pivot or takedown pin. The width and height of the removal tool may be slightly smaller than the width and height of the channel of the pivot pin or takedown pin. The distal end of the removal tool may taper from a top surface to the bottom surface to form a sharp point or tip.

Abstract: A functionalized tissue having covalently bound antibiotics and methods for producing the functionalized tissue having bound antibiotics comprising; providing a tissue having a sufficient number of primary amine groups on the tissue; coupling and deprotecting one or more F-moc AEEA linkers using HATU chemistry to the primary amine groups; and coupling an antibiotic to said AEEA linkers using HATU chemistry.

Abstract: The oxidative functionalization of olefins is a common method for the formation of vicinal carbon-heteroatom bonds. However, oxidative methods to transform allenes into synthetic motifs containing three contiguous carbon-heteroatom bonds are much less developed. The use of bicyclic methylene aziridines (MAs), prepared via intramolecular allene aziridination, as scaffolds for functionalization of all three allene carbons, among other reactions, is described herein.

Abstract: An electronic module test assembly including a frame, an array of contact pins, and at least one latch. The frame has a recess formed therein for receiving an electronic module. The array of contact pins is anchored to the frame. The contact pins have resiliently depressible terminals forming a resiliently depressible contact array in the recess. The latch is movably mounted to the frame for latching the electronic module to the frame. The latch is movable relative to the frame and engages an outer edge of the electronic module when the electronic module is disposed against the resiliently depressible contact array. The resiliently depressible contact array biases the electronic module against the latch.
