Abstract: Systems, methods, and computer-readable media for flow stitching network traffic flow segments across middleboxes. A method can include collecting flow records of traffic flow segments at a first middlebox and a second middlebox in a network environment including one or more transaction identifiers assigned to the traffic flow segments. Sources and destinations of the traffic flow segments can be identified with respect to the first middlebox and the second middlebox. Corresponding subsets of the traffic flow segments can be stitched together to from a first stitched traffic flow at the first middlebox and a second stitched traffic flow at the second middlebox. The first and second stitched traffic flows can be stitched together to form a cross-middlebox stitched traffic flow across the first middlebox and the second middlebox. The cross-middlebox stitched traffic flow can be incorporated as part of network traffic data for the network environment.

Abstract: An optical phase shifter may include a waveguide core that has a top surface, and a semiconductor contact that is laterally displaced relative to the waveguide core and is electrically connected to the waveguide core. A top surface of the semiconductor contact is above the top surface of the waveguide core. The waveguide core may include a p-type core region and an n-type core region. A p-type semiconductor region may be in physical contact with the n-type core region of the waveguide core, and an n-type semiconductor region may be in physical contact with the p-type core region of the waveguide core. A phase shifter region and a light-emitting region may be disposed at different depth levels, and the light-emitting region may emit light from a phase shifter region that is in a position adjacent to the light-emitting region.

Abstract: The present invention provides a method of determining or identifying or isolating a cell-penetrating peptide (CPP) or analog or derivative thereof having cell-type selectivity and/or at least capable of passing through a Blood Brain Barrier of an animal subject. This invention also provides CPPs and analogs and derivatives thereof, such as those set forth in SEQ ID NOs: 1-27 of the Sequence Listing, and compositions comprising one or more of the CPPs, including conjugates in which a CPP or analog or derivative thereof is linked to a cargo molecule. The invention also provides methods for transporting cargo molecules across cell membranes to specific locations within cells, and for treating, preventing and/or diagnosing diseases that are treatable by a cargo molecule to which a CPP or analog or derivative of the invention is attached. The invention also provides tailored peptide libraries for use in identifying or isolating CPPs.

Abstract: There is a communications network node comprising a transmitter or a receiver configured to communicate with a plurality of other nodes via an interconnection medium interconnecting the node and the other nodes. The node is frequency synchronized with regard to signal transmission or reception, via a frequency synchronization mechanism, with at least one of the other nodes. The node has at least one store holding phase data relating to an amount of phase asynchrony and path characteristics between the node and at least one of the other nodes. A phase controller uses the stored data to adjust phase used by the node such that the recovery of data when communicating with at least one other node is facilitated.

Abstract: Aspects of the present disclosure describe optical phased array structures and devices in which hyperbolic phase envelopes are employed to create focusing and diverging emissions in one and two dimensions. Tuning the phase fronts moves focal point spot in depth and across the array. Grating emitters are also used to emit light upward (out of plane). Adjusting the period of the gratings along the light propagation direction results in focusing the light emitted from the gratings. Changes in the operating wavelengths employed moves the focal spot along the emitters.
