The parameter value includes a value of: a distance between the node and an adjacent node of the plurality of nodes, a dimension of the node, a configuration of an arrangement in which the plurality of nodes are arranged on the side, a composition of a material coating the node, and/or a material composition of the node.

Abstract: For communicating securely between network nodes, a method transmits a port knock sequence comprising ordered empty protocol packets from an origination node to a destination Internet Protocol (IP) address of a destination node. The port knock sequence encodes at least one vocabulary phrase. The method transmits the length of the at least one vocabulary phrase to first and second helper nodes. The method generates a corresponding substitute phrase for each at least one vocabulary phrase through communication between the first helper node and the second helper node. The method receives the corresponding substitute phrase for each at least one vocabulary phrase at the origination node and the destination node. The method generates a node nonce based on the at least one corresponding substitute phrase. The method securely communicates between the origination node and the destination node using the node nonce.

Abstract: Transgenic silkworms stably expressing hagfish thread keratin genes or composite silkworm/hagfish thread keratin genes are disclosed. The exogenous hagfish thread keratin genes are stably integrated into a defined site of the fibroin heavy chain intron or a fibroin light chain intron of silkworms. Synthetic hagfish thread keratin proteins and composite hagfish thread keratin-silkworm genes and proteins are provided. The expression of exogenous hagfish thread keratin genes is driven by the endogenous fibroin heavy chain promoter, improving the genetic stability of transgenic silkworms. The composite silkworm/hagfish thread keratin fibers exhibit exceptional mechanical performance, compared to normal silkworm silk fibers and other transgenic silkworm fibers.

Also provided are expression vectors, nucleic acids, polypeptides, and recombinant microbial cells useful in carrying out the process and prodrugs produced by the process.

Abstract: For tracking a target, a method receives a combined signal comprising a target signal reflected by a target and a transmitter signal not reflected by the target, wherein the transmitter signal is comprised of a plurality of orthogonal frequency division multiplexing (OFDM) subcarrier signals. The method calculates a signal Fourier transform for the combined signal to obtain the complex symbols. The method estimates a sequence of channel state information. The method estimates CSI over for non-pilot OFDM subcarriers of the combined signal to obtain CSI for a sequence of M OFDM symbols. The method computes a CSI Fourier transform for the sequence of CSI for a plurality of OFDM subcarriers. The method estimates a CSI Doppler frequency by matching a Fourier transform template to the CSI Fourier transform. The method computes each of a target position and a target velocity vector for the target.

Abstract: A counter-swarm firework includes a shell casing, multiple streamers positioned in the shell casing, a burst charge positioned in the shell casing and configured to disperse the multiple streamers from the shell casing when discharged, a pusher plate positioned in the shell casing between the burst charge and the multiple streamers, a fire suppressant layer positioned between the burst charge and the pusher plate, and a kick charge configured to launch the shell casing and its contents prior to discharging the burst charge. The fire suppression layer may be configured to suppress heat generated by the discharge of the burst charge.
