A Fully Ultrasonic Approach for Combined Functional Imaging and Neuromodulation in Behaving Animals

09/01/2019 - 05/31/2022
Two very recent advancements have been transforming the field of medical ultrasound. First, the revolutionary discovery of ultrasound neuromodulation, which non-invasively targets and modulates activity in specific regions of the brain. Second, contrast-enhanced super-resolution, which can image microvessels at resolutions as small as ten microns, an order of magnitude smaller than the ultrasound diffraction limit, and at greater depths. To achieve this generational leap in performance super-resolution contrast imaging requires that tens of thousands of frames of data be rapidly acquired and analyzed, making this technique much more computationally and algorithmically intensive than standard ultrasound imaging. Furthermore, the skull presents a unique challenge because it aberrates and generates reverberations, which reduce the resolution detectability of contrast agents. Consequently, transcranial super-resolution imaging would be difficult if not impossible to translate to the brain in its current form with current clinical hardware, especially if 3-D imaging is desired (which it is for functional imaging). Combining ultrasonic neuromodulation with functional imaging relies on MRI to target the ultrasound focus and to assess the brain’s functional response. However, confinement in a magnet bore, which typically requires anesthesia and limits the range observable behavioral scenarios. Furthermore, fMRI is slow compared to the time scale of the neural response, which is on the order of tens to hundreds of milliseconds. There is a solution to these limitations, which our group proposes to achieve in this project by developing a fully ultrasonic approach that combines 3-D super-resolution functional imaging with neuromodulation in a single integrated ultrasound platform that can be used on behaving animals. Time reversal, in conjunction with a highly accurate acoustic simulation tool that we have developed, can correct for the aberrations induced by the skull morphology accurately focus ultrasound and improve detectability. New software and implementation approaches designed at UNC Chapel Hill, including our innovative adaptive multi-focus beamforming approach, will simultaneously target multiple regions of the brain and enable full 3-D volume acquisitions at volume frame rates over 5000 FPS, suitable for rapid (hundreds of milliseconds) functional imaging. Recent advances in ultrasound hardware will enable ultra-high frame rate processing. Our research team at UNC Chapel Hill is partnering with a world-leading transducer group at NCSU to develop a lightweight wearable neurostimulation array. Ultra-fast processors, large RAM buffers, GPUs, and high-bandwidth data transfer hardware will be utilized to handle challenging adaptive beamforming tasks and massive data acquisition. Our approach will be validated in partnership with Vanderbilt, who have been pioneering the field of neuromodulation in non-human primates. Our motivation is to develop an integrated ultrasound platform as a new approach for neurostimulation and blood flow-based functional ultrasound imaging in the whole brain, with a non-ionizing, non-invasive, low-cost technology that could be used for monitoring and modulation in behaving animals.

As one of the 5G envisioned services, ultra-reliable and low-latency communications (URLLC) aim to provide secure data transmissions from one end to another with ultra-high reliability and deadline-based low latency requirements, enabling tactile Internet, mission-critical Internet of Things, and vehicle safety applications. Meanwhile, unmanned aerial vehicles (UAVs) for wireless communications has drawn much attention as the mass production of high-performance, low-cost, intelligent UAVs become more practical and feasible, which empowers more functional diversity for 5G networks. Based on the PIs’ expertise at the three institutions, Dr. Lin at North Carolina State University (NC State), Dr. Kobayashi at Nagoya University (NU), and Dr. Shi at The University of Adelaide (AU), this project will initiate collaborative research discussion and external grant planning for introducing a holistic software-defined wireless architecture that ensures URLLC in 5G UAV ecosystems. Several teleconferences and onsite discussion at three institutions will be established. The project will also organize an international workshop in the International Conference on Materials and Systems for Sustainability (ICMaSS) 2019 in Nagoya, Japan, to bring together researchers in all relevant areas. The PIs will actively seek the feedback from industry partners to work with us on developing, testing and deploying the 5G UAV framework. Moreover, PIs plan to develop a visiting/exchange Ph.D. student program designed to allow graduate students to spend a semester (preferably in summer) at the PIs’ institutions for academic exchanges to enhance the cross-linkage between the lines of research pursued by the team members.

Theoretical modeling of the proposed 2D/3D hybrid structure and its application to the hot electron transistors will be undertaken in close coordination with the experimental effort for accurate understanding and optimization of the performance. Considering the large mismatch in the vertical and lateral dimensions of the device, a hierarchical approach will be adopted for the analysis. In particular, an atomistic modeling based on first-principles density functional theory and non-equilibrium Green’s function methods will be pursued to describe hot electron dynamics in the emitter-collector junctions. Detailed information such as electronic structures, band offset, and tunnel barrier potential will be extracted as a function of layer thickness, stacking sequence, atomic termination, etc. A variety of material combinations will be explored for the hybrid structure with a focus on 2D nitrides. The impact of the defects will also be examined numerically.

We propose AERPAW: Aerial Experimentation and Research Platform for Advanced Wireless, a first-of-its-kind aerial wireless experimentation platform to be developed in close partnership between NCSU, Wireless Research Center of North Carolina (WRCNC), Mississippi State University (MSU), University of South Carolina (USC), City of Raleigh, Town of Cary, Town of Holly Springs, North Carolina Department of Transportation (NCDOT), and numerous other project partners. With a major focus being on aerial communications within low altitude airspace, AERPAW will develop a software defined, reproducible, and open-access advanced wireless platform with experimentation features spanning 5G technologies and beyond. NCSU, USC, and MSU researchers have existing UAS experimentation capabilities and ongoing experimental research activities involving wireless technologies spanning software defined radios (SDRs), LTE, WiFi, ultra-wideband (UWB), IoT, and millimeter wave (mmWave), which will form the initial baseline framework for the AERPAW platform. To deploy AERPAW, NCSU will work closely with NCDOT’s Integration Pilot Program, a three-year FAA project that allows BVLOS UAS experimentation for medical supply delivery in North Carolina, in close collaboration with NCSU, several UAS companies, municipalities, and a medical institution. Initial flight tests have already started within the Raleigh area, and will be expanding to other parts of the state in 2019 and beyond. Any additional FAA permits, as necessary, will be secured by AERPAW team in close collaboration with NCDOT.

The proposed research will study a hybrid RF/VLC network where the number of IoT users that require wireless communications is significantly
larger than the number of RF base stations (BSs). Our research is organized into three synergistic research thrusts. First, in Thrust-1, a novel, hybrid NOMA VLC/RF wireless access will be introduced, for which surge-resilient RAT/LED assignment and NOMA transmission techniques will be developed. The proposed approach can schedule UEs/MTDs based on their QoS needs under traffic surges and/or network failures. Subsequently, Thrust-2 will introduce novel, resilient cross-system learning for self-organizing resource management, and explore the network resilience against censored information, i.e., information that is not available to the network due to failures or environmental changes. The proposed cross-system learning framework allows for feedback between multiple learning algorithms operating across RATs to devise optimal resource allocation strategies that guarantee the required QoS levels across RATs, even when information is censored. Finally, Thrust-3 will introduce testbeds and SDR experimental platforms to evaluate the findings from the first two research thrusts on multihop RF/VLC communications and LED selection with NOMA.

In the current state-of-the-art machine learning based real-time control and decision-making in large-scale complex networks such as electric power systems is largely bottlenecked by the curse of dimensionality. Even the simplest linear quadratic regulator design demands cubic numerical complexity. The problem becomes even more complex when the network model is unknown, due to which an additional learning time needs to be accommodated. In this 3-year NSF CPS proposal, we take a new stance for solving this problem, and propose a hierarchical or nested machine learning-based scheme for real-time control of extreme-dimensional networks. Our approach will be to design appropriate projection matrices by which a network can be divided into disparate sets of non-overlapping groups depending on the low-rank properties of their controllability grammian, and multiple sets of composite controllers can be learned independently for each group using model-free reinforcement learning. Accordingly, the control goals of the network will also be decomposed into local (microscopic) and global (macroscopic) reward functions. Local controllers will be designed via privacy preserving group learning, and the global controllers via model reduction and averaging. Sparsity-promoting structures will be imposed on top of the local controllers to reduce their communication complexity. Deep learning algorithms based on historical events will be used to train recurrent neural networks so that they can rapidly predicting these sparse projections after any disturbance event in the network. Throughout this entire exercise, wide-area control of power systems using streaming Synchrophasor data from Phasor Measurements Units (PMUs) will be treated as a driving example. Results will be validated using standard IEEE models, a simplified model of the Japanese power grid with high-scale solar penetration, and an Opal-RT model of the Duke Energy power grid integrated with the ExoGENI cloud computing network at the FREEDM Systems Center.

Recent years have witnessed that online social networks (OSNs) change the way people interact with each other and trigger a tremendous amount of attention in various disciplines because of their extensive applications and massive useful data. They are simply too large to be downloaded or stored locally, and the sheer size forces us to resort to ‘sampling’ for estimation and inference of massive networks in a compact manner.
In particular, sampling via random-walk crawling has been commonly considered as the only viable solution, which is feasible via the public yet restrictive local-neighborhood-only interfaces provided by OSNs,
for estimating the properties of users (nodes), their relationships (edges), and more sophisticated relationship among multiple users (subgraph patterns). Whereas there have been many efforts in the literature to advance our understanding on sampling via random-walk crawling, there are still important challenges that have been generally overlooked and remained unsolved.
The long-term goal of the proposed research is to build a strong theoretical foundation for the optimal sampling strategies and the optimal control of multiple random walks for the estimation and inference of massive networks in the cost-constrained environments in reality, going beyond the current Markov Chain Monte Carlo (MCMC) driven statistical theories and practices for graph sampling in the literature.
