Abstract: Systems and methods for using multi-view learning to leverage highly informative, high-cost, psychophysiological data collected in a laboratory setting, to improve post-traumatic stress disorder (PTSD) screening in the field, where only less-informative, low-cost, speech data are available. Partial least squares (PLS) methods can be used to learn a bilinear factor model, which projects speech and EEG responses onto latent spaces, where the covariance between the projections is maximized. The systems and methods use a speech representation based on a combination of audio and language descriptors extracted from spoken responses to open-ended questions.

Abstract: Embodiments described herein relate to generating an image of an acoustic field associated with an underwater region. A plurality of submersible sensing devices (SSDs) are disposed so as to be substantially separate from each other in an underwater region, wherein each respective SSD is configured to execute a sink/float mission. During at least a portion of the sink/float mission, within each SSD, an environmental sensor measures at least one environmental parameter, a position sensor detects position information, an acoustic detection sensor detects at least one underwater signal, and a data recording system records mission data. After the sink/float mission, a processor receives mission data from the SSDs and generates an acoustic field image. Advantageously, during the sink/float mission some SSDs can transmit an orthogonal high time-bandwidth signal to help prevent interference between SSD during acoustic detection.

Abstract: A system, device, and method are provided to control dense-mode multicast traffic across a multilayer system containing an upper network and a tunnel across a lower network. An upstream multicast tunneling edge device (MTED) may indicate to downstream MTEDs, via control messages, the presence of a multicast source, group (SG) pair. The MTEDs may serve as routers or as intelligent bridges in the upper network. Each downstream MTED may create a forwarding state for the SG pair, determine tunnels for which the downstream MTED is to serve as an exit device and configure the tunnels to deliver the traffic. Lower network MTEDs of a tunnel may determine whether to transport multicast data for each SG pair such that multicast traffic routed by a corresponding MTED is carried. An MTED may be able to receive, through the tunnel, multicast traffic for one SG pair even after pruning itself for another SG pair.
