Abstract: A microfluidic diagnostic device with a three-dimensional (3D) flow architecture comprises a polymeric body having first and second opposing surfaces and comprising first flow channels in the first opposing surface, second flow channels in the second opposing surface, and connecting flow passages extending through a thickness of the polymeric body to connect the first flow channels to the second flow channels, thereby defining a continuous 3D flow pathway in the polymeric body. The microfluidic diagnostic device also includes a first cover adhered to the first opposing surface to seal the first flow channels, a second cover adhered to the second opposing surface to seal the second flow channels, and one or more access ports in fluid communication with the continuous 3D flow pathway for introducing liquid reagent(s) and/or a sample into the polymeric body.

Abstract: An image processing method includes defining relations between entities of a target of which a motion is to be predicted from an image of a first time point based on a feature vector of the entities, estimating a dynamic interaction between the entities at the first time point based on the defined relations between the entities, predicting a motion of the entities changing at a second time point based on the estimated dynamic interaction, and outputting a result to which the motion predicted at the second time point is applied.

Abstract: A segmentation method and segmentation apparatus are provided, where the segmentation method includes receiving image frames comprising a current frame and an adjacent frame to the current frame, determining a feature map to aggregate the image frames based on temporal information between the current frame and the adjacent frame, extracting a feature of a region of interest (ROI) corresponding to instances included in the current frame from the feature map, predicting a class of an object corresponding to the ROI based on the feature of the ROI, and segmenting the instances by correcting an amodal mask predicted corresponding to the class of the object based on the feature of the ROI.

Abstract: In a vehicle-to-vehicle wireless communication system utilizing certificates to verify trustworthiness of received communications, a method for distributing a list of certificate revocations to vehicles in the communication system. At least one main station transmits a list of certificate revocations to at least one vehicle and the vehicle thereafter transmits the list of certificate revocations to other vehicles in the communication network. Each of the other vehicles in the communication network updates its list of certificate revocations in response to the receipt of the list of certificate revocations from another vehicle in the system. The other vehicles thereafter transmit their updated list of certificate revocations to other vehicles in the system.

Abstract: In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a Certificate Authority having both a private key and a publicly distributed key, a method for allocating multiple certificates for each vehicle which are assigned to each vehicle in the communication network. The method includes the step of assigning a unique secret key k to each vehicle in the communication network. The Certificate Authority then creates a plurality of public key and private key encryption pairs for each vehicle and each encryption pair is associated with an index i. A plurality of certificates are then created with one certificate for each value of the index. A revocation list comprising the secret keys is maintained by the Certificate Authority so that all encryption pairs assigned to a particular vehicle may be revoked by the secret key k corresponding to that vehicle.

Abstract: A method for exchanging messages containing reliable information between nodes in an ad hoc network, such as a vehicle ad hoc network. The method includes the steps of providing a public key for a PKI encrypted certificate authority signature to all nodes known to transmit reliable information. Each node transmits a signal containing node identification information and the PKI encrypted certificate authority signature associated with that node. Each node also receives like signals from other nodes and then decrypts the certificate authority signatures from the received signals by using the certificate authority public key to ascertain the authenticity of the received certificate authority signatures and the reliability of the received message.
