Abstract:
A solution for forming at least a portion of an active layer of an electronic or electro-optic device includes a solvent, an additive mixed with the solvent to provide a solvent-additive blend, and a solute that includes at least one of a transition metal, an alkali metal, an alkaline earth metal, Al, Ga, In, Ge, Sn, or Sb dissolved in elemental form in the solvent-additive blend. The additive is selected from the group of additives consisting of NR1R2NHCOOH, NH2N—HCONHNH2, NH2COOH.NH3, NH2NHC(═NH)NH2.H2CO3, NH2NHCSNHNH2, NH2NHCSSH and all combinations thereof. R1 and R2 are each independently selected from hydrogen, aryl, methyl, ethyl and a linear, branched or cyclic alkyl of 3-6 carbon atoms. Methods of producing the solution, a method of producing a Kesterite film on a substructure and devices made with the solutions and methods are also provided.
Abstract:
Technologies for a human computation framework suitable for answering common sense questions that are difficult for computers to answer but easy for humans to answer. The technologies support solving general common sense problems without a priori knowledge of the problems; support for determining whether an answer is from a bot or human so as to screen out spurious answers from bots; support for distilling answers collected from human users to ensure high quality solutions to the questions asked; and support for preventing malicious elements in or out of the system from attacking other system elements or contaminating the solutions produced by the system, and preventing users from being compensated without contributing answers.
Abstract:
A method and an apparatus for maintaining a quality of service (QoS) for a multi-media packet data service in a transport network is provided. The method comprises determining a first packet loss indication for a first flow of QoS traffic packets. The method further comprises determining a second packet loss indication for a second flow of QoS traffic packets, wherein the determination of the first packet loss indication for the first flow of QoS traffic packets is independent from the determination of the second packet loss indication for the second flow of QoS traffic packets. The method further comprises determining whether to drop the first flow of QoS traffic packets based on the first packet loss indication or to drop the second flow of QoS traffic packets based on the second packet loss indication. By using per-flow independent packet loss statistics to determine whether that flow should be dropped and gradually dropping such QoS flows having the most impact on a desired QoS performance, a reduced number of QoS flows may be dropped to recover a data transport network from congestion.
Abstract:
The invention relates to a cognitive SIMO network access method based on cooperative relay, wherein a cognitive base station collects channel responses in a network and judges whether the cognitive users can cooperate with a primary user to achieve the target transmission rate required by the primary user or not, if so, a cognitive SIMO network is accessible to a frequency band licensed to the primary user; otherwise, the cognitive SIMO network is non-accessible. The access method can enable a plurality of the cognitive users and the primary user to simultaneously use the same licensed spectrum in the same geographical position, on the premise of ensuring the target transmission rate of the primary user, and further improve the utilization efficiency of the spectrum as far as possible. As the access method is based on cooperative communication, the nearer the distance from the cognitive network to the primary network is, the greater the network throughput can be achieved; and furthermore, a large-range network coverage can be realized, so the deficiencies in the existing cognitive radio access ways are made up.

Abstract:
A channel decoding method and decoder are disclosed. The decoding method is based on a Circular Viterbi Algorithm (CVA), rules out impossible initial states one by one through iterations according the received soft information sequence, and finally finds the global optimal tail-biting path. In the present invention, all impossible iterations are ruled out through multiple iterations, and only the initial state having most likelihood with the received sequence survives. The algorithm is finally convergent to an optimal tail-biting path to be output. In addition, the method also updates a metric of a maximum likelihood tail-biting path (MLTBP) or rules out impossible initial states through the obtained surviving tail-biting path, thereby effectively solving the problem that the algorithm is not convergent due to a circular trap, providing a practical optimal decoding algorithm for a tail-biting convolutional code, reducing the complexity of an existing decoding scheme, and saving the storage space.

Some aspects of the present disclosure relate to systems and methods for accelerated dynamic magnetic resonance imaging (MRI). In an example embodiment, a method includes acquiring undersampled MRI data corresponding to a set of images associated with an area of interest of a subject, and separating an image of the set of images into image regions. The method also includes performing motion tracking for each of the image regions, grouping the motion-tracked image regions into clusters, and applying a sparsity transform to the clusters, to form sparsity-exploited, transformed image regions. The method further includes forming a set of merged images from the plurality of sparsity-exploited, transformed image regions, and updating the set of merged images based on data fidelity, to form an updated set of estimated images.
