  • Publication number: 20160185875
    Abstract: Disclosed herein is a hinge antibody capable of being selectively activated in a target cell or tissue to treat a condition therein. The hinge antibody includes a functional antibody, two inhibitory domains and four cleavable linkers. The functional antibody is capable of treating the condition in an activated state, and has two light chains and two heavy chains. Each inhibitory domain includes a hinge domain of an immunoglobulin and consists of two peptide arms. Each cleavable linker includes a peptide substrate cleavable by an enzyme specifically or highly expressed in the target cell or tissue, and connects one of the peptide arms of the inhibitory domains to the N-terminal of one of the light chains and heavy chains of the functional antibody. Also disclosed herein are methods for preparing and using this hinge antibody.

  • Publication number: 20160019474
    Abstract: Listings and reviews of listings can be processed to identify descriptive attributes for locations associated with the listings. To do this, a corpus of words is generated for various locations based on listings in the locations and reviews of those listings. An expected frequency, and per-location frequency for each word is determined. These numbers are in turn used to determine a number of high frequency listing locations, and a number of below expected frequency listing locations for each word. Based on a comparison of the number of high frequency listing locations and the number of below expected frequency listing locations of a word with an attribute reference number, the word can be identified either as an attribute that is likely descriptive of the location, or not.

  • Patent number: 9225458
    Abstract: A configurable wavelength-selective cross-connect (WSXC) device having an array of optical ports in which at least some of the ports are configurable to operate as common ports or as plural ports. The configurable WSXC device includes a MEMS mirror array whose mirrors are tiltable in a manner that enables, e.g., reconfigurations of the configurable WSXC device that result in a change of the number of common ports therein. In one possible configuration, the configurable WSXC device can operate as 1×M1 wavelength-selective switch, where M1+1?P, and P is the total number of optical ports in the array of optical ports. In another possible configuration, the configurable WSXC device can operate as a bank of n 1×M2 wavelength-selective switches, where n is a positive integer greater than one, and n(M2+1)?P.

  • Publication number: 20130041278
    Abstract: A method for diagnosis of diseases adopted on an electronic stethoscope which includes at least two sound receiving portions, a noise control portion, a processing portion, a data portion and an output portion. The method includes: first, the sound receiving portions receive sound signals issued from a patient's lungs included external noises; next, the sound signals are sent to the noise control portion which eliminates the external noise, and the processing portion to be overlapped and intensified; then characteristic values are retrieved from the sound signals to be compared with disease sound signal data in the data portion; finally the output portion outputs a diseases judgment result. Thus the electronic stethoscope can perform automatic interpretation of diseases to reduce human erroneous diagnostic judgment. Users also can get preliminary understanding of their body conditions when doctors are absent.
