Patent number: 10749554Abstract: A communication system transmits an input block of bits over a communication channel using a prefix tree that maps a dyadic distribution of compositions of output symbols to prefixes of variable lengths. A path to each leaf of the prefix tree is defined by a prefix formed by a unique sequence of binary values of a length equal to a depth of the leaf. Each leaf is associated with a composition that has at least a number of unique permutations equals to two in a power of a length of a suffix of the block of input bits. The system selects a composition identified in the prefix tree by a prefix, permutes the selected composition according to a suffix, and transmits the permuted composition over a communication channel. The compositions are selected to reduce one or combination of energy and kurtosis of transmission.Type: GrantFiled: October 2, 2019Date of Patent: August 18, 2020Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: David Millar, Toshiaki Koike-Akino, Kieran Parsons, Keisuke Kojima

Patent number: 10554309Abstract: A method decodes an optical signal transmitted over an optical channel from a transmitter to a receiver. The method produces, from the transmitted optical signal, a digital signal including received data symbols and received pilot symbols and determines phase noise on the pilot symbols using a statistical probability distribution of phase noise on the optical channel and errors between phases of the received pilot symbols and the transmitted pilot signals. The method estimates phase noise on the data symbols using an interpolation of the phase noise on the pilot symbols and compensates the digital signal with the phase noise on the data symbols to produce a filtered signal with an equalized phase. The method demodulates and decodes the filtered signal to produce an estimate of the transmitted optical signal.Type: GrantFiled: January 18, 2018Date of Patent: February 4, 2020Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: David Millar, Milutin Pajovic, Toshiaki Koike-Akino, Keisuke Kojima, Kieran Parsons

Publication number: 20200016262Abstract: A variety of targeting moiety peptide epitope complexes (TPECs) are described in different embodiments. In each of the embodiments, however, a targeting moiety may be used to deliver the TPEC to an area of unwanted cells, allowing for a therapeutic effect to be delivered locally. The TPEC also contains a plurality of T-cell epitopes. The TPEC further comprises cleavage sites that release the T-cell epitopes from the targeting agent, and in some embodiments from each other, when they are in the microenvironment of the unwanted cells. Although the arrangement and number of T-cell epitopes varies in different embodiments described herein, once cleaved from the targeting agent (and any neighboring T-cell epitopes), the T-cell epitopes function by stimulating an immune response against the unwanted cells.Type: ApplicationFiled: September 3, 2019Publication date: January 16, 2020Applicant: The University of BirminghamInventors: Mark Cobbold, David Millar
