Abstract: A dispersion-compensation microstructure fiber uses pure silica glass as the background material. It includes the core, the first-type defects, the second-type defects and the cladding. The air holes in the fiber cross section are arranged in the equilateral triangle lattice with the same adjacent air-hole to air-hole spacing. The core is formed by omitting 1 air hole. The first-type defects are formed by the 6 air holes locating at the vertices of hexagonal third-layer porous structure surrounding the core and their surrounding background material. The second-type defects are formed by the air holes in the first air-hole layer surrounding each first-type defect and their surrounding background material. The second-type defects act as the porous structure to surround the first-type defects and the fundamental defect modes, and can also combine with the first-type defects to act as the core of the second-order defect modes.

Abstract: Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

Abstract: Technology is disclosed herein for early erase termination as a counter-measure for erase disturb. Multiple erase blocks of NAND memory cells are erased in parallel during an erase procedure. Erasing multiple erase blocks in parallel can place considerable strain on the circuitry that generates the erase voltage. If there is significant leakage current in one of the erase blocks the magnitude of the erase voltage for all of the erase blocks may drop. The erase blocks are tested sequentially for leakage current during the first erase loop while the erase voltage is applied to only the erase block under test. If any erase block fails the leakage current test that erase block is removed from the erase procedure. One or more additional erase loops are then performed with only those erase blocks that passed the leakage current test simultaneously receiving an erase voltage, thereby preventing erase disturb with early termination.

Abstract: A double-tilt sample holder for TEM, comprising: it comprise the main body of sample holder body, front-end tilt stage, drive rod, linkage, tilt axis, rotation axis, fixed axis of drive rod and sample loading stage. The axis hole is arranged at the front-end tilt stage, which is connected to the main body of the sample holder body by the tilt axis. The linkage, the boss slot and the drive rod slot are connected by the rotation axis. Two through movement guide grooves are designed symmetrically at both sides of the front-end of sample holder body, and the drive rod is fixed by the fixed axis of the drive rod, which restricts the drive rod to move reciprocally in a straight line driven by the linear stepping motor at the back-end of the main body of the holder body, further leading the tilt stage to rotate around the tilt axis. The tilt angle of the sample loading stage can be precisely controlled by the high precision linear stepping motor in the apparatus.

Abstract: A double-tilt in-situ mechanical sample holder for TEM based on piezoelectric ceramic drive belongs to the field of material microstructure-mechanical properties in-situ characterization, and it comprise two parts of sample holder shaft body and piezoelectric ceramic drive system. The sample holder shaft body comprise tilt stage, sample holder, linear stepping motor, drive rod, drive linkage. The piezoelectric ceramic drive system comprise piezoelectric ceramic loading stage, piezoelectric ceramic, connecting base and the sample loading stage realizing stretch or compression function. The double-axis tilt of the samples in X and Y axis directions is realized by the reciprocating motion back and forth of the drive rod driven by the linear stepping motor. The stretch or compression of the samples is realized by applying voltage on the piezoelectric ceramic to generate displacement and push the sample loading stage by the connecting base.
