Abstract: Multi-stage distributed beamforming for distributed mosaic wireless networks is provided. Embodiments described herein present systems, devices, and methods that provide increased range, data rate, and robustness to interference and jamming. A distributed mosaic wireless network includes a transmitter, a receiver, and one or more distributed clusters of radios referred to herein as mosaics or relay mosaics. Each mosaic consists of several distributed, cooperative radio transceivers (e.g., mosaic nodes) that relay a signal sent by the transmitter towards the receiver. In some embodiments, a single-stage beamforming technique is implemented whereby the transmitter sends a signal to a first mosaic, which then relays this signal by beamforming to the receiver. In some embodiments, a multi-stage beamforming technique is implemented whereby the transmitter sends a signal to a first mosaic, which then relays this signal by beamforming to a second mosaic, which then relays this signal by beamforming to the receiver.

Abstract: Collapsible branched anastomosis devices allow for the formation of percutaneous vascular anastomoses using a Seldinger wire technique. This minimally invasive approach eliminates the need for a large surgical incision and also avoids the use of time consuming hand-suturing. The devices collapse to a fraction of their expanded volume and are configured to fit within a delivery sheath for over the wire delivery through a small incision in a blood vessel.

Abstract: A system and method for modulating optogenetic vagus neurons in a noninvasive and transcutaneous manner is disclosed. The system and method comprises a two-dimensional array of organic light emitting diodes (OLEDs), a voltage-generating unit, a control unit, and a feedback loop. The array is placed on a subject's outer ear. Because the array is flexible, it can be closely placed on the skin of the outer ear. The array can deliver optical therapy and monitor heart rate variability (HRV) of the subject simultaneously, and the pixels of the array can be individually addressed. The voltage-generating unit generates pulsed voltage to the OLEDs. The control unit is connected to the array and controls the array and therapeutic patterns. The feedback loop uses the HRV to identify the therapeutic patterns.

Abstract: A method for determining a perturbation energy of a quantum state of a many-body system includes constructing a wave function that approximates the quantum state by adjusting parameters of the wave function to minimize an expectation value of a zeroth-order Hamiltonian. The zeroth-order Hamiltonian explicitly depends on a finite mass of each of a plurality of interacting quantum particles that form the many-body system, the quantum state has a non-zero total angular momentum, the wave function is a linear combination of explicitly correlated Gaussian basis functions, and each of the explicitly correlated Gaussian basis functions includes a preexponential angular factor. The perturbation energy is calculated from the wave function and a perturbation Hamiltonian that explicitly depends on the finite mass of each of the plurality of interacting quantum particles. The perturbation energy may be added to the minimized expectation value to obtain a total energy of the quantum state.
