Abstract: An access device constructs a beacon frame, where the beacon frame includes a newly added field, and the newly added field represents multiple data guard interval lengths supported by the access device. The access device broadcasts the beacon frame, so that a terminal selects an available guard interval length matching a data guard interval length supported by the terminal from the beacon frame, and performs data communication with the access device by using the available guard interval length. Data communication between the access device and the terminal can be implemented when the access device supports multiple data guard interval lengths.

Abstract: Apparatuses and methods for harvesting ambient energy involve repeated circuit reconfiguration. An apparatus includes a primary charge storage device, a first secondary charge storage device, a second secondary charge storage device, and switching circuitry. The switching circuitry is configured to cyclically alter connection of the first and second secondary charge storage devices between a series state and a parallel state.

Abstract: Novel gene deletions and translocations involving chromosome 2 resulting in fusion proteins combining part of Anaplastic Lymphoma Kinase (ALK) kinase with part of a secondary protein have been identified herein in human solid tumors, e.g. non-small cell lung carcinoma (NSCLC). Secondary proteins include Echinoderm Microtubule-Associated Protein-Like 4 (EML-4) and TRK-Fusion Gene (TFC).

The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ALK kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.

Abstract: Systems, apparatuses and methods for harvesting ambient energy involve an electrically conductive charge-carrying movable electrode. An apparatus includes an electrically conductive charge-carrying electrode, a first dielectric interface region, a second dielectric interface region, and at least one reference electrode. The first and second dielectric interface regions differ in surface charge density. In certain aspects, the movable electrode moves proximate and relative to the first and second dielectric interface regions in response to receipt of ambient energy, thereby providing first and second capacitances. The first capacitance differs from the second capacitance, and/or the first surface charge density differs from the second surface charge density. Movement of the movable electrode in combination with the differing capacitances and/or charge densities results in energy accumulation, thereby enabling ambient energy to be harvested efficiently and effectively.
