    • One aspect of the disclosure is directed to a system and method for determining the propagation delay for a signal to traverse an optical fiber between two transceivers. The method is performed by a first network element and includes transmitting a message to a second transceiver over a first optical fiber. The method further includes configuring both network elements such that the first NE receives a reply message from the second NE on the first optical fiber. This reply message includes an indication of the internal time for the second NE to transmit the reply message. Accordingly the one way propagation delay on the first optical fiber can be determined. Another aspect is directed to a system and method for using the determined one way propagation delay to synchronize clocks of the two NEs using a symmetric network synchronizing protocol such as precision timing protocol, and correcting for differences in the one way propagation delays which make up the round trip propagation delay. Some embodiments can do this without stopping the operation of the network while pausing (buffering) data flows while the one way propagation delays are determined.

    • Screening assays and methods of employing the screening assays designed to identify potential inhibitors of amyloidal neurodegenerative disease. The screening assays comprises providing a membrane construct disposed on a substrate and contacting the membrane construct with Aβ peptide capable of forming an Aβ peptide ion channel in the construct. The membrane construct is then contacted with a test compound. Aβ peptide ion channel activity is determined after the construct has incubated with the Aβ peptide in the presence and in the absence of the test compound. A reduction in the Aβ peptide ion channel activity of the membrane construct contacted with the test compound in comparison to a different membrane construct contacted with the same Aβ peptide in the absence of said test compound indicates that the test compound is an inhibitor of amyloidal neurodegenerative disease.

    • The invention relates to a method for converting thermal energy into mechanical work. Said method comprises the following steps which are performed as a cycle: A liquid work medium is fed from a supply reservoir (1) to a work container (3); the work medium in the work container (3) is heated by a first heat exchanger (5); a sub-amount of the work medium flows from the work container (3) to a pneumatic-hydraulic-converter (8), a hydraulic medium from the pneumatic-hydraulic-converter (8) is compressed in a work machine (9) in order to convert the hydraulic work of the hydraulic medium into mechanical work; the work medium from the pneumatic-hydraulic-converter (8) is fed back into the supply reservoir (1) and the hydraulic medium is returned into the pneumatic-hydraulic-converter (8). The invention also relates to a device for carrying out said method.

    • A device for treating spinal stenosis having an implant body structure sized and configured to be positioned between the spinous processes of two adjacent vertebrae. The device may have a body portion having a first end portion, a second end portion and a sleeve between the first and second end portions. The device may also have at least two retainers positioned in and extendable from the body portion. A mechanism positioned within the body portion may be used to move the retainers between a retracted position and a deployed position. When the retainers are in the deployed position, the retainers may be positioned around the spinous process of at least one of two adjacent vertebrae. A plurality of installation tools which may be used to install the device are also disclosed.
