SUMMARY:BE Seminar Series: Applied Topology in Biological Systems
DESCRIPTION:Though rooted in pure mathematics\, algebraic topology has recently enabled novel analysis techniques for biological data. Specifically\, the method called persistent homology which employs ideas from topology to characterize the voids in a complex network. In this talk\, I will briefly introduce persistent homology and give an overview of how we have recently applied this tool to answer questions in neuroscience and semantic learning. Finally\, I will provide additional examples of topology in biology and suggest how current research in pure algebraic topology may soon aid in our understanding of complex systems.

SUMMARY:ESE Seminar: "Control of Light and Heat for New Energy Applications"
DESCRIPTION:Light carries energy and heat\, and plays a key role in many energy-conversion processes. The capabilities\nto tailor electromagnetic energy transfer at the nanoscale represent important opportunities for novel\nenergy applications. In this talk I will present two sets of studies integrating experiments and theory. In\nthe first part\, I will discuss how to use near field electromagnetic energy transfer for energy conversion\nand photonic refrigeration. I will begin by showing an experiment achieving a 40-fold enhancement of\nthermophotovoltaic conversion rates\, by reducing the distance between a thermal emitter and a\nphotovoltaic cell to the nanoscale. This lays the foundation for exploring near-field thermophotovoltaics\nfor waste heat recovery. I will then show a demonstration of active photonic refrigeration through control\nof the chemical potential of photons. This points to a fundamentally new\, promising way for solid state\nrefrigeration by combining nanoscale photonics and optoelectronics.\nIn the second part\, I will discuss how to turn the cold outer space to a thermodynamic resource for passive\ncooling and energy efficiency. I will introduce our first demonstration of passive radiative cooling to\nbelow the ambient air temperature under direct sunlight. Next I will show an experiment achieving\npassive cooling to 42 ˚C below the ambient temperature\, pointing to new regimes of applications such as\nfood preservation in remote areas. I will also show results of lowering the temperature of a solar absorber\nby 13 ˚C while maintaining the sunlight absorption\, pointing to significant efficiency improvement for\nsolar cells. Finally\, I will give an overview of my future research directions.

SUMMARY:CIS Seminar: "Computer Security for Emerging Technologies"
DESCRIPTION:As our world becomes more computerized\, security and privacy takes on a prominent role in allowing us to enjoy the benefits of new technologies without the risks. Addressing the new challenges that come with this role requires a change in how we approach and solve problems in computer security. My vision is that we must view computer security as a whole-system property ranging from the physical-layer right up to applications and end-users. In line with this vision\, my approach to computer security involves formulating the right security problem to work on\, addressing design-level issues by constructing strong defenses at the appropriate layer of abstraction\, and challenging common assumptions to understand realistic threats. In this talk\, I will give several examples of my approach and vision\, focusing on emerging technologies that span the digital-to-physical interface. I will cover technical results at various level of abstraction\, including analysis techniques that found exploitable design-level vulnerabilities in closed-source smart home platforms\, a new design for trigger-action platforms that provides strong integrity guarantees\, and an analysis of how realistic attacks on machine learning can occur in the physical world. Finally\, I will share my vision of the future of security and privacy research in an increasingly connected world.

SUMMARY:MEAM Seminar: "Force\, Shape\, and Motion in Collective Cell Migration"
DESCRIPTION:Cells migrate collectively to form tissues\, to heal wounds\, and\, in cancer\, to metastasize. During these biological processes\, the collective migration exhibits a transition from a solid-like state\, wherein cell positions remain fixed\, to a fluid-like state\, wherein cells flow freely and rearrange their positions with their neighbors. Recent mechanics-based models and experiments have demonstrated that this transition can be predicted by average cell shape\, with cells having more elongated shapes and greater perimeters more easily sliding past their neighbors. At each cell-cell interface\, it has been proposed that active actomyosin contraction generated within the cell cortex acts as an effective surface tension tending to reduce each cell’s perimeter. Cell-cell adhesions have the opposite effect\, tending to reduce the surface tension\, thereby increasing the perimeter. It is unclear how cells regulate these competing factors in a confluent monolayer. This presentation will describe our investigation of the factors affecting cell surface tension and cell perimeter\, and the corresponding effects on collective migration. Our experiments use monolayers of Madin-Darby Canine Kidney cells and quantify cell forces\, shapes\, and motion. With this experimental data\, we test the theoretical predictions relating cell shape and motion.

SUMMARY:CIS Seminar: "Machine Learning: Why Do Simple Algorithms Work So Well?"
DESCRIPTION:While state-of-the-art machine learning models are deep\, large-scale\, sequential and highly nonconvex\, the backbone of modern learning algorithms are simple algorithms such as stochastic gradient descent\, or Q-learning (in the case of reinforcement learning tasks). A basic question endures—why do simple algorithms work so well even in these challenging settings?\n\nThis talk focuses on two fundamental problems: (1) in nonconvex optimization\, can gradient descent escape saddle points efficiently? (2) in reinforcement learning\, is Q-learning sample efficient? We will provide the first line of provably positive answers to both questions. In particular\, we will show that simple modifications to these classical algorithms guarantee significantly better properties\, which explains the underlying mechanisms behind their favorable performance in practice.

SUMMARY:John A. Quinn Distinguished Lecture: "Some Uses and Misuses of Equilibrium Thermodynamics"
DESCRIPTION:We will discuss a number of legitimate and of wrongful applications of the Second Law of Thermodynamics\, in particular\, in the screening of chemical processes. We consider how ideas of equilibrium thermodynamics and statistical mechanics can be of value in some non-equilibrium situations\, particularly in the cases of very slow diffusion and reaction.

SUMMARY:CIS Seminar: " Natural language to structured knowledge representations"
DESCRIPTION:Computing machinery such as smartphones are ubiquitous\, and so will be smart home appliances\, self-driving cars and robots in the near future. Enabling these machines with natural language understanding abilities opens up potential opportunities for the broader society to benefit from\, e.g.\, in accessing the world’s knowledge\, or in controlling complex machines with little effort.\n\nIn this talk\, we will focus on accessing knowledge stored in knowledge-bases and text documents in a colloquial manner. We will do so by processing language into programs that perform reasoning. The main questions we will explore are 1) which inductive biases on neural architectures are well suited for processing language to programs? 2) what is the role of linguistic structure? and 3) can we build models which produce answers without generating an explicit program?

SUMMARY:CIS Seminar: "Security for All: Modeling Structural Inequities to Design More Secure Systems"
DESCRIPTION:Users often fall for phishing emails\, reuse simple passwords\, and fail to effectively utilize “provably” secure systems. These behaviors expose users to significant harm and frustrate industry practitioners and security researchers alike. As consequences of security breaches become ever more grave\, it is important to study why humans behave seemingly irrationally. In this talk\, I will illustrate how modeling the effects of structural inequities — variance in skill\, socioeconomic status\, as well as culture and gender identity — can both explain apparent irrationality in users’ security behavior and offer tangible improvements in industry systems. Modeling and mitigating security inequities requires a combination of techniques from economic\, data scientific\, and social science methodologies to develop new tools for systematically understanding and mitigating insecure behavior. \nThrough novel experimental methodology\, I empirically show strong evidence of bounded rationality in security behavior: Users make mathematically modelable tradeoffs between the protection offered by security behaviors and the costs of practicing those behaviors\, which even in a highly usable system may outweigh the benefits\, especially for less resourced users. These findings emphasize the need for industry systems that balance structural inequities and accommodate behavioral variance between users rather than one-size-fits-all security solutions. More broadly\, my techniques for modeling and accounting for inequities have offered key insights in growing technical areas beyond security\, including algorithmic fairness.

SUMMARY:MEAM Seminar: "Nanoparticle Heating for Therapeutics\, Regenerative Medicine and Diagnostics"
DESCRIPTION:Gold and iron oxide nanoparticles have unique and tunable properties that allow transduction of optical (light)\, or radiofrequency (RF) electromagnetic fields to affect heating of biomaterials at multiple scales. This talk will explore the underlying physics and relative advantages of each form of nanoparticle heating for therapeutic treatment of cancer or other disease by heating (i.e. magnetic hypothermia or photothermal cancer therapy). In addition\, this same heating helps improve regenerative medicine by “nanowarming” vitrified (i.e. cryopreserved) biomaterials back to a transplantable state through rapid and uniform warming that avoids crystallization and cracking. This nanoparticle warming addresses an important technology bottleneck for both large systems (i.e. tissues and organs) and smaller systems (i.e. embryos and oocytes). In summary\, this talk demonstrates the growing opportunites for nanoparticle heating in biomedical applications.

SUMMARY:PICS Seminar: "Coupled Multiphysics Models of Cardiac Hemodynamics: From Fundamental Insights to Clinical Translation"
DESCRIPTION:  \n\n\nAbstract: The mammalian heart has been sculpted by millions of years of evolution into a flow pump par excellence. During the typical lifetime of a human\, the heart will beat over three billion times and pump enough blood to fill over 60 Olympic-sized swimming pools. Each of these billions of cardiac cycles is itself a manifestation of a complex and elegant interplay between several distinct physical domains including electrophysiology and mechanics of the cardiac muscles\, hemodynamics\, and flow-induced movement of the cardiac valves. Another multiphysics interaction that is key to hemostasis involves hemodynamics and blood biochemistry. The clotting cascade\, which is a natural response to injury\, is initiated by a sequence of biochemical reactions that are strongly modulated by the local flow conditions. In this regard\, how the chambers and valves of a healthy heart manage to avoid thrombosis\, remains an open question. The presence of heart conditions such as myocadial infarction (MI)\, cardiomyopathies\, valve anomalies and atrial fibrillations\, disturb the hemostatic balance and can lead to thrombosis with devastating sequalae such as stroke and MI. Computational models for thrombogenesis in the cardiac system have the potential to provide useful insights into this important phenomenon. In the current talk\, I will describe high-fidelity chemo-fluidic modeling of thrombogenesis in the left heart and demonstrate how fundamental insights from these studies are translated into clinically relevant metrics. Application of these models to thrombogenesis in transcatheter aortic valves will also be described.

SUMMARY:ESE Seminar: "Confluence of Electromagnetics\, Circuits and Systems Enables The Third Wireless Revolution"
DESCRIPTION:Integrated circuits have fueled several revolutions that have deeply impacted modern society\, including the computing revolution\, the internet and the first two wireless revolutions. We are at the dawn of the third wireless revolution\, which I call the Wireless Mobile Reality revolution. Over the next fifteen years\, new wireless paradigms spanning from radio frequencies to millimeter-waves and terahertz will change the way in which we interact with the real world\, through applications such as mobile virtual and augmented reality\, vision quality imaging\, gesture recognition and bio- and materials-sensing. \nHowever\, at the same time\, integrated circuits are starting to run out of steam – technology scaling is no longer yielding better transistors that are faster and lower power. Therefore\, circuit design needs to be refreshed with new tools and techniques that draw inspiration from the layers below (electromagnetics and device physics) and the layers above (communication systems and networking). \nIn this talk\, I will describe research along these lines from the CoSMIC lab at Columbia University. I will start by describing a new approach to breaking Lorentz reciprocity to engineer high-performance non-reciprocal components\, such as gyrators\, isolators and circulators. I will then talk about how these integrated non-reciprocal circulators enable practical integrated full-duplex wireless radios. Finally\, I will talk about the FlexICoN project at Columbia which is taking a holistic and cross-layer view of full-duplex networks from the physical layer to the networking layer. I will also briefly touch upon other work from CoSMIC lab in the same vein related to high-power\, high-efficiency millimeter-wave radios\, MIMO radios\, opto-electronic LIDARs and city-scale wireless testbeds.

SUMMARY:CIS Seminar: "Data Discovery: Unleashing the Value of Data"
DESCRIPTION:Organizations use only a small portion of all data they own.\nConsequently\, most of the potential value is untapped. This happens\nbecause their analysts suffer a data discovery problem: when solving a\ntask that requires data\, analysts spend more time finding the relevant\ndata than solving the task at hand. The core problem is that there is\nnot adequate infrastructure to support the many different discovery\nproblems organizations face. Hence\, finding data remains largely a\nmanual and time-consuming process. \nIn this talk I’ll present Aurum\, a system that radically changes how\nusers interact with their organizations’s data. With Aurum users can\nsolve discovery problems in minutes instead of weeks. To achieve this\,\nAurum has three novel features: 1) it makes data discovery programmable\nso users can solve many different discovery problems by writing\ndifferent programs; 2) it solves data discovery queries fast\, so users\ncan solve their problems in minutes instead of weeks; 3) it scales to\nlarge amounts of data\, so no relevant data is left behind. In addition\,\nI’ll explain how Aurum handles not only structured data such as tables\nin databases\, data lakes\, and spreadsheets\, but also unstructured data\nsuch as PDF files\, word documents\, and even conversations from Slack\nchannels. \nI’ll conclude with a vision for how to make data easier to work with and\nto program\, a key ingredient needed to exploit all data available in\norganizations and enable new applications.

SUMMARY:BE Seminar: "Microfluidics and Immuno-Materials for Organs-on-a-Chip"
DESCRIPTION:This presentation will describe microfluidic technologies to conveniently produce life-like pulsatile flows along with applications to study of lung injury\, enhancement of in vitro fertilization\, and analysis of frequency-dependent cellular responses. The microfluidic technologies range from adaptation of piezo-electric actuator arrays from Braille displays to design of microfluidic circuits that can be designed to switch fluid flow on and off periodically on their own. The presentation will also describe engineered materials to mimic an aspect of the innate immune system to combat bacterial infection. More specifically\, reconstituted chromatin microwebs inspired by neutrophil extracellular traps. Using a defined composition reconstituted chromatin microweb\, we reveal impact of microweb DNA-histone ratio on bacteria capture. Additionally\, we found that E. coli\, including clinical isolates and resistant strains\, are killed more efficiently by the last-resort antibiotic\, colistin\, when bound to microwebs. Recent efforts towards incorporation of these materials into human cell systems will also be described. Time permitting\, topics on organoids\, fibrosis\, liquid-liquid phase separation\, and scaling may be incorporated.

SUMMARY:ESE Seminar: "Software\, Architecture\, and VLSI Co-Design for Efficient Task-Based Parallel Runtimes"
DESCRIPTION:Fast-paced changes across the computing stack are creating opportunities for innovation by bridging software\, architecture\, and VLSI. Cross-cutting research is challenging\, but it can expose key insights that would otherwise be hidden by abstractions. In this talk\, I will demonstrate a cross-stack approach to improve the efficiency of task-based parallel runtimes\, which are important because they underpin the parallelization of state-of-the-art graph analytics and machine learning frameworks. Shifting the focus downward\, I will discuss a cross-stack approach that addresses key circuit-level challenges in integrated voltage regulation. To finish the talk\, I will discuss my future plans to apply a cross-stack research approach to expand beyond the perceived limits of intelligence on the edge and also to decrease the challenges of complex ASIC design with hardware design techniques based on Lego-like tiling.

SUMMARY:CIS Seminar: "Language as a Scaffold for Grounded Intelligence:
DESCRIPTION:Abstract:\n\nNatural language can be used to construct rich\, compositional descriptions of the world\, highlighting for example entities (nouns)\, events (verbs)\, and the interactions between them (simple sentences). In this talk\, I show how compositional structure around verbs and nouns can be repurposed to build computer vision systems that scale to recognize hundreds of thousands of visual concepts in images. I introduce the task of situation recognition\, where the goal is to map an image to a language-inspired structured representation of the main activity it depicts. The problem is challenging because it requires recognition systems to identify not only what entities are present\, but also how they are participating within an event (e.g. not only that there are scissors but they are they are being used to cut). I also describe new deep learning models that better capture compositionality in situation recognition and leverage the close connection to language ‘to know what we don’t know’ and cheaply mine new training data. Although these methods work well\, I show that they have a tendency to amplify underlying societal biases in the training data (including over predicting stereotypical activities based on gender)\, and introduce a new dual decomposition method that significantly reduces this amplification without sacrificing classification accuracy. Finally\, I propose new directions for expanding what visual recognition systems can see and ways to minimize the encoding of negative social biases in our learned models.

SUMMARY:CIS Seminar: "Towards Embodied Visual Intelligence"
DESCRIPTION:What would it mean for a machine to see the world? Computer vision has recently made great progress on problems such as finding categories of objects and scenes\, and poses of people in images. However\, studying such tasks in isolated disembodied contexts\, divorced from the physical source of their images\, is insufficient to build intelligent visual agents. My research focuses on remarrying vision to action\, by asking: how might vision benefit from the ability to act in the world\, and vice versa? Could embodied visual agents teach themselves through interaction and experimentation? Are there actions they might perform to improve their visual perception? How might they construct visual plans to achieve long-term action goals? In my talk\, I will set up the context for these questions\, and cover some strands of my work addressing them\, proposing approaches for self-supervised learning through proprioception\, visual prediction for decomposing complex control tasks\, and active perception. Finally\, I will discuss my long-term vision and directions that I hope to work on in the next several years

SUMMARY:ESE Seminar: "Ultra-Low-Power Neural Interfaces: from Monitoring to Diagnosis and Therapy"
DESCRIPTION:Implantable and wearable medical devices are increasingly being developed as alternative therapies for intractable diseases. In particular\, undertreated neurological disorders such as epilepsy\, migraine\, and Alzheimer’s disease are of major public health concern around the world\, driving the need to explore such new approaches. Despite significant advances in neural interface systems\, the small number of recording channels in existing technology remains a barrier to their therapeutic potential. This is mainly due to the fact that simultaneous recording from a large number of electrodes imposes stringent energy and area constraints on the integrated circuits that interface with these electrodes. In this talk\, I will first discuss an efficient compressive sensing framework for multichannel cortical implants. Next\, I will present the design of our sub-microwatt per channel closed-loop seizure control device and both its in-vivo and offline performance. I will then discuss our latest work on the integration of machine learning algorithms for on-chip classification of neural data. Finally\, I will give examples of how these results may be used towards designing new devices\, to enhance the lives of millions of people suffering from disabling neurological conditions in future.

SUMMARY:ESE Seminar: "Towards Robotic Manipulation - Understanding the World Through Contact"
DESCRIPTION:Why is robotic manipulation so hard? As humans\, we are unrivaled in our ability to dexterously manipulate objects and exhibit complex skills seemingly effortlessly. Recent research in cognitive science suggests that this ability is driven by our internal representations of the physical world\, built over a life-time of experience. Our predictive ability is complemented by our senses of sight and touch\, intuitive state-estimation\, and tactile dexterity. Given the complexity of human reasoning\, skill\, and hardware\, it is not surprising that we have yet to replicate our abilities in robots. In order to bridge this gap\, we must take a holistic perspective on manipulation and build robotic systems that understand and interpret their physical world through contact. \nIn this talk\, I will present two methodologies that strive to this end: First\, a physics-based\nmethodology for the inference of contact forces and system parameters of rigid-bodies systems making and breaking contact. Second\, how a robot can learn the physics of playing Jenga using a hierarchical-learning methodology purely from data. I will conclude the talk by touching upon data-augment contact models and providing perspectives on building robotic systems that embody intelligent manipulation.

SUMMARY:ESE Seminar: "From Nanotech to Living Sensors: Unraveling the Spin Physics of Biosensing at the Nanoscale"
DESCRIPTION:I am a quantum engineer interested in how quantum physics informs biology at the nanoscale. \nAs a physicist\, I have developed high-performance nanosensors that essentially worked due to room-temperature quantum effects in noisy environments. Currently\, I am focusing on “living sensors” — organisms and cells that respond to minute stimuli\, routinely outperforming technological probes in awe-inspiring ways. Unveiling and controlling the underlying physical mechanisms employed by “living sensors” impact: the engineering of ultrasensitive\, bio-inspired electromagnetic probes; the elucidation of mesmerizing natural feats such as animal navigation; and the advancement of therapeutics for metabolic-related diseases. \nSubstantial in vitro and physiological experimental results are consistent with the fact that similar spin physics might underlie biosensing modalities as varied as organismal magnetic field detection and metabolic regulation of oxidative stress in cells. \nCan spin physics be established — or refuted! — to account for physiologically relevant biosensing phenomena\, and be manipulated to technological and therapeutical advantage? This is the broad\, exciting question that I wish to address in my scientific career.

SUMMARY:ESE Seminar: "Quantum Nanophotonics: Engineering Atom-Photon Interactions on a Chip"
DESCRIPTION:Abstract: The ability to engineer controllable atom-photon interactions is at the heart of quantum optics and quantum information processing. In this talk\, I will introduce a nanophotonic platform for engineering strong atom-photon interactions on a semiconductor chip. I will first discuss an experimental demonstration of a spin-photon quantum transistor [1]\, a fundamental building block for quantum repeaters and quantum networks. The device allows a single spin trapped inside a semiconductor quantum dot to switch a single photon\, and vice versa\, a single photon to flip the spin. I will discuss how the spin-photon quantum transistor realizes optical nonlinearity at the fundamental single quantum level\, where a single photon could switch the transmission of multiple subsequent photons [2]. I will next discuss the promise of realizing photon-mediated many-body interactions in an alternative solid-state platform based on a more homogeneous quantum emitter\, silicon-vacancy (SiV) color centers in diamond. I will introduce our efforts in creating strong light-matter interactions through photonic crystal cavities fabricated in diamond [3]\, and the use of cavity-stimulated Raman emission to overcome the remaining frequency inhomogeneity of the emitters [4]. Finally\, I will outline the exciting prospects of applying inverse designed nanophotonic structures into quantum optics\, and their potential applications in engineering photon-mediated atom-atom interactions.\nReferences\n[1] S.

SUMMARY:CIS Seminar: " Rethinking the hardware-software contract:   Enabling practical and general cross-layer optimizations"
DESCRIPTION:Layered abstractions in the computing stack are critical to building complex systems\, but the existing *interfaces* between layers restrict what can be done at each level. Enhancing cross-layer interfaces–specifically\, the hardware-software interface–is crucial towards addressing two important and hard-to-solve challenges in computer systems today: First\, significant effort and expertise are required to write high-performance code that harnesses the full potential of today’s diverse and sophisticated hardware. Second\, as a hardware or system designer\, architecting faster and more efficient systems is challenging as the vast majority of the program’s semantic content and programmer intent gets lost in translation with today’s hardware-software interface. Moving towards the future\, these challenges in programmability and efficiency will be even more intractable as we architect increasingly heterogeneous and sophisticated systems. \nIn this talk\, I will highlight my work [ISCA‘15\, MICRO‘16\, ISCA‘18\, ISCA‘18] on how to design rich cross-layer abstractions that provide layered interfaces to directly communicate higher-level program semantics and intent from the application to the lower levels of the stack. In doing so\, we can effectively bridge the so-called “semantic gap” between applications and computer systems\, and enable a wide range of cross-layer optimizations in future systems with a unifying interface. I will discuss how cross-layer approaches with these abstractions can significantly enhance (1) performance and efficiency by enabling the system to adapt to application characteristics and (2) programmability and portability by enabling application software to easily leverage diverse underlying hardware resources without specific knowledge of system details.  For example\, daunting aspects of programming GPUs can be made much simpler with a rich cross-layer programming abstraction. I will describe how such abstractions can be designed to be highly practical and low-overhead\, requiring only small additions to existing abstractions.

SUMMARY:ESE Seminar: "Towards Socially-Aware Autonomy for Mobility-Efficient Smart Cities"
DESCRIPTION:As cities grow everywhere\, and urban roadways become overburdened\, efficient strategies are required for improving mobility. With the prevalence of smart sensing and Internet of Things (IoT) devices\, such as smartphones and smart intersections\, the physical infrastructures of our cities are being connected to the cyber world. As a result\, cities are becoming smart. Moreover\, with the emergence of new and inevitable technologies\, such as autonomous and connected vehicles\, mobility on demand systems\, and electric vehicles\, smart cities are rapidly evolving. As we experience the arrival of such technologies\, there is an opportunity to reclaim urban mobility. However\, a blind utilization of these technologies may deflect us from reaching this goal. In my research\, I leverage the connectivity that is inherent in smart cities as well as the opportunities that new technologies such as autonomous and connected vehicles provide\, to study the efficient operation of smart cities via management strategies that can guarantee overall societal benefits. \nIn this talk\, I will focus on the societal-scale mobility implications of the increased deployment of autonomous and connected vehicles in mixed-autonomy traffic networks\, where both human-driven and autonomous vehicles will coexist on the roads. I will first talk about the mobility implications of selfish autonomy\, in which autonomous cars are not aware of their overall impact and simply attempt to optimize their own travel benefits. In this context\, I will introduce conditions under which an increase in the fraction of autonomous vehicles on a traffic network\, even when operating selfishly\, results in increased societal mobility benefits. Conversely\, I will show that if these conditions do not hold\, overall network mobility may degrade as the fraction of autonomous vehicles increases. Having shown the negative consequences that the increased deployment of autonomous and connected vehicles may have on the operation of traffic networks\, I will further discuss the use of traffic management strategies\, such as pricing\, which can guarantee the overall societal-scale efficiency of traffic networks with mixed vehicle autonomy.
