Silicon-based Integrated Sensors with On-chip Antennas: From THz Pulse Sources to Miniaturized Spectrometers Pulse Sources to Miniaturized Spectrometers

Speaker: Aydin Babakhani, UCLA
Time: 11:00 am - 12:00 pm Sep 5, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: Today’s silicon process technology makes it possible to integrate everything from antennas to processors on a single chip at almost no cost. This creates new opportunities for implementing complex sensors and systems on a millimeter scale. To create such devices, an understanding of physics, waves, electromagnetics, and high-frequency electronics is essential. In this presentation, I will show how the convergence of these fields has resulted in single-chip picosecond pulse radiators, wirelessly synchronized chips with sub-psec synchronization accuracy, miniaturized spectrometers, and wirelessly powered sensors and actuators. In the first section of the talk, I will present techniques for generating and detecting picosecond pulses, based on a novel laser-free Digital-to-Impulse (D2I) radiation. This technology can produce broadband pulses with a record width of 1.9psec that cover a frequency spectrum from 30GHz to 1.1THz and that have a resolution of 2Hz at 1THz. I will discuss how this technology enables us to perform broadband THz spectroscopy, hyper-spectral 3D imaging, and Tbits/sec wireless communication. In the second part, I will present my work on precision time transfer and wireless synchronization of widely spaced chips. This technique eliminates the wires between the elements of a distributed array and makes it possible to build a highly flexible large aperture. In this section, I will also present my work on optical locking of microwave oscillators, which achieves a picosecond timing accuracy over a 1.5m distance. In the third section of the talk, I will focus on miniaturized spectrometers and sensors. I will discuss an Electron Paramagnetic Resonance (EPR) spectrometer that is based on a single-chip full-duplex transceiver for detecting paramagnetic chemicals and free radicals. The EPR sensor technology developed in my laboratory has been successfully deployed in major oil and gas fields in the United States and Canada. This technology is used to monitor the concentration of asphaltenes (a chemical that clogs oil wells) in real-time and to minimize the use of environmentally hazardous chemical inhibitors in energy production. I will further present my recent work on wirelessly powered microchips with on-chip antennas. These microchips are designed to perform sensing, actuation, and localization. I will provide examples of such microchips being used to pace the heart of a sheep and to trigger the leg movement of a rat. Finally, I will discuss the future directions of my research on building wirelessly powered single-chip electronic drugs for medical applications and electronic tracers for energy exploration as well as for industrial monitoring.

Physical Human-Robot Interaction in Robotic Neuro-Rehabilitation

Speaker: S. Farokh Atashzar, The University of Western Ontario, Canada
Time: 11:00 am - 12:00 pm Sep 6, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: The incidence rate of age-related neuromuscular disorders and movement disabilities is rapidly increasing worldwide due to an aging society. While better medical care has increased survival rates, it has resulted in more patients in need of neuro-rehabilitation and assessment services. Stroke is the leading cause of motor disabilities. There are more than 6 million stroke survivors living in the United States. About 90% of survivors experience long-term disabilities and often require labor- intensive kinesthetic rehabilitation services, for extended periods. This has placed a significant burden on healthcare systems. The situation is particularly concerning in remote areas where healthcare systems lack sufficient resources to serve the population of patients in need.

A potential solution is to develop smart mechatronic, robotic, and telerobotic technologies that provide safe and effective means of in-hospital and in-home kinesthetic neurorehabilitation and assessment services. In this regard, robotic rehabilitation systems have revolutionized the field of movement therapy. Combining sensorized force-enabled robotic systems with sophisticated virtual and augmented reality environments has provided a unique multimodal framework for neurorehabilitation and for studying sensorimotor characteristics of patients with neuromuscular disorders. Thus, during the last decade, utilization of robotic systems in neurorehabilitation and neuroscience has significantly increased.

Although there are specific advantages to the use of neuro-rehabilitation robotic systems, there still exist several technical and control challenges, such as (a) absence of direct physical interaction between the clinician and the patient who uses the robot, (b) limited accessibility in remote areas, (c) low transparency of the force field generated by the robotic system, and (d) questionable compatibility of the force field with biomechanical characteristics of the patient’s limbs. The latter case relates to the stability (and safety) of robotic rehabilitation systems, and is of particular concern when high rehabilitative forces are needed for severely-disabled patients, when the robot is to be used in a patient’s home, and when the patient experiences involuntary movements (that can mislead the control unit of a robotic system). The above-mentioned challenges will be discussed in this talk, and possible solutions will be presented. In this regard, some research projects focusing on telerobotic rehabilitation systems, stabilizing controllers for physical human-robot interaction, and tremor estimation and cancelation techniques will be introduced. It should be noted that in addition to the use of robots for therapeutic purposes, these systems have a high potential for studying various sensorimotor aspects of neuromuscular disorders. Thus, the talk will be concluded by some brief examples of robots that have been used to better understand neurological movement disorders such as Parkinson’s Disease, Focal Hand Dystonia, and Cerebral Palsy.

This talk will be presented with a multidisciplinary audience in mind. The focus will be on topics related to neuro-rehabilitation robotics. Due to the time limitation, topics related to surgical robotics will not be presented; however, the audience is more than welcome to ask questions regarding top lines of research in the area of surgical robotics as well.

Physics and modeling of negative capacitance field-effect transistors

Speaker: Yogesh Singh Chauhan, Indian Institute of Technology Kanpur (IITK), India
Time: 11:00 am - 12:00 pm Sep 18, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: The ongoing scaling of CMOS technology is now reaching its limit, due to supply voltage reduction being restricted by the subthreshold swing (SS) of 60mV/decade achievable at room temperature owing to Boltzmann transport of the charge carriers. Concept of negative capacitance proposed to achieve a sub-60mV/decade SS is currently seen as one of the potential solutions to the problem. A “negative capacitance transistor (NCFET)” employs a ferroelectric material in the gate stack of a FET providing a negative capacitance and thereby an “internal voltage amplification” at the gate of the internal FET which helps in reducing SS. Several experiments have successfully demonstrated an improved SS with the bulk MOSFET, FinFET, and 2D FETs. The improvement in subthreshold characteristics is also accompanied with the advantage of an increased ON current relative to the reference FET as has been observed both in simulation studies and experiments. In this talk, I will discuss the physics and modeling of various NCFET structures and impact of this new transistor on circuits including processors.

Imitating the Clairvoyant Oracle: From Information Gathering to Grounded Visual Navigation via Natural Language

Speaker: Debadeepta Dey, Microsoft
Time: 11:00 am - 12:00 pm Sep 25, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: In the adaptive information gathering problem, a robot is required to select an informative sensing location using the history of measurements acquired thus far. While there is an extensive amount of prior work investigating effective practical approximations using variants of Shannon’s entropy, the efficacy of such policies greatly depends on the geometric distribution of objects in the world. On the other hand, the principled approach of employing online POMDP solvers is rendered impractical by the need to explicitly sample online from a posterior distribution of world maps. We present a novel data-driven imitation learning framework to efficiently train information gathering policies. The policy imitates a clairvoyant oracle - an oracle that at training time has full knowledge about the world map and can compute maximally informative sensing locations. We analyze the learnt policy by showing that offline imitation of a clairvoyant oracle is implicitly equivalent to online oracle execution in conjunction with posterior sampling. This observation allows us to obtain powerful near-optimality guarantees for information gathering problems possessing an adaptive submodularity property. As we demonstrate on a spectrum of 2D and 3D exploration problems with aerial vehicles, the trained policies enjoy the best of both worlds - they adapt to different world map distributions while being computationally inexpensive to evaluate.

We also show in very recent work that this idea of imitating a clairvoyant oracle (in a learning-to-search framework) yields better performing policies for the task of visual navigation from natural language instructions in indoor environments. I will also provide a quick overview of ongoing exciting reinforcement and imitation learning related projects in MSR Redmond.

Circuits: Terahertz (THz) and Beyond Seminar Series: Terahertz Communications: From Nanomaterials to Ultra-broadband Networks Frequencies

Speaker: Josep Miquel Jornet, University at Buffalo
Time: 11:00 am - 12:00 pm Sep 27, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: Wireless data traffic has grown exponentially in recent years due to a change in the way today's society creates, shares and consumes information. This change has been accompanied by an increasing demand for higher speed wireless communications, anywhere, anytime. Following the current trend, wireless Terabit-per-second (Tbps) links are expected to become a reality within the next ten years. In this context, Terahertz (THz)-band (0.1-10 THz) communication is envisioned as a key wireless technology of the next decade. The THz band will help overcome the spectrum scarcity problems and capacity limitations of current wireless networks, by providing an unprecedentedly large bandwidth. In addition, THz-band communication will enable a plethora of long-awaited applications, both at the nano-scale and at the macro-scale, ranging from wireless massive-core computing architectures and instantaneous data transfer among non-invasive nano-devices, to ultra-high-definition content streaming among mobile devices and wireless high-bandwidth secure communications. In this seminar, an in-depth view of THz-band communication networks will be provided. First, the state of the art and open challenges in the design and development of THz transceivers and antennas will be presented, with special emphasis on novel hybrid graphene/semiconductor plasmonic devices. Then, the current progress and future research directions in terms of channel modeling, physical and link layers design, will be tackled in a bottom-up approach, defining a roadmap for the development of this next frontier in wireless communication.

Circuits: Terahertz (THz) and Beyond Seminar Series: Monolithic Phased Arrays: Radiofrequencies to Optical Frequencies

Speaker: Hossein Hashemi, USC
Time: 11:00 am - 12:00 pm Oct 3, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: In 1909, accepting the Nobel Prize for Physics for “contributions to the development of wireless telegraphy”, Karl Ferdinand Braun stated “It had always seemed most desirable to me to transmit the waves, in the main, in one direction only.” He also presented a schematic of a three-antenna system that can form a desired beam in one direction. In the following decades, this simple scheme was advanced to large-scaled phased arrays used for military radars in WWII and beyond. In 1965, Gordon Moore predicted that advancement in integrated circuit technology will enable monolithic microwave phased arrays that can revolutionize radar. Nearly four decades later, monolithic microwave silicon phased arrays were reported for the first time. Today, monolithic radio frequency, microwave, and millimeter wave phased arrays are turning mainstream in commercial products including automotive radars and high speed wireless transceivers including those for the upcoming 5G wireless standards.

Shortly following the invention of laser in 1960, electronically-steerable laser beam was conceived to be useful in optical radars (nowadays known as lidars), free-space optical communications with moving transmitter and/or receiver, and projection television. While optical beam steering has been around for several decades, monolithic optical phased arrays are more recent thanks to advancements in fabrication technology. Very recently, the interest in optical beam-steering and monolithic optical phased arrays has increased thanks to the application of low-cost compact lidar in self-driving cars. Other potential application of optical phased arrays include free-space optical communications, imaging, sensing, display, and holography.

This talk will cover the basics, history, and applications of phased arrays followed by selected state-of-the-art realizations of phased array systems and related components from radio frequencies up to optical frequencies.

Brief History of Radio

Speaker: Fred Harris, UCSD
Time: 11:00 am - 12:00 pm Oct 8, 2018
Location: 2MTC Room 10.099, Brooklyn, NY

Abstract: The history of radio is a remarkable account of a disruptive technology that truly changed the world. What a remarkable idea, Communications at a distance (communicating faster than a man or woman can run). It is a concept that nearly eclipses the wonders of tomorrow foretold by the famous futurists such as H. G. Wells and Jules Verne. It is the stuff of science fiction made real! Radio and its progeny; television, satellites, cell phones, Zigbee, radar, and others, have had, and continue to have, enormous social, political, and economic impact on us all.

This presentation is a non-technical walk along a technology path with acknowledgements to familiar names of scientists, inventors, innovators, and industrialists with light reflections of their contributions to the discoveries and developments that have taken us through an unfinished journey that started 190 years ago. At one level, radio is circuits, equations, vacuum tubes, transistors, amplifiers, antennae, and modulation theory. At another level it is a fascinating record of people whose contributions have brought us the applied magic we call radio. Do the names Oersted, Faraday, Maxwell, Helmholtz, Hertz, Marconi, Poulsen, de Forest, Armstrong, Popoff, Sarnoff, and Shannon, sound familiar? Join us in this fun walk down memory lane to gently prod your recollections of these giants who have come before us.

As an aside, I am not a historian but rather a technologist. I use the history of radio in my modem design class to give students a perspective of why and how we arrived at certain design structures. I point out that design compromises made in past radios were appropriate for the time they were made but that we should not propagate these compromises to next generation radios. We have technologies and capabilities not available to our predecessors and we should use them to improve rather than to emulate previous designs. I also find that it is fun and enlightening to know the history.

Modern Artificial Intelligence Seminar Series: The AI Trinity: Data + Algorithms + Infrastructure

Speaker: Anima Anandkumar, Caltech
Time: 11:00 am - 12:00 pm Oct 9, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: AI at scale requires a perfect storm of data, algorithms and cloud infrastructure. Modern deep learning has relied on large labeled datasets for training. However, such datasets are not easily available in all domains, and are expensive/difficult to collect. By building intelligence into data collection and aggregation, we can drastically reduce data requirements. Additionally, algorithmic and infrastructure innovations now make it possible to train models at scale. In future, we will see more integration of these three pillars to advance AI.

Speaker: Mark Rodwell, University of California, Santa Barbara
Time: 11:00 am - 12:00 pm Oct 11, 2018
Location: 370 Jay, Seminar Room 202, Brooklyn, NY

Abstract: With the RF bands below ~5GHz soon to be exhausted, industry is poised to move to 5G systems, with carriers at 28, 38, 57-71(WiGig), and 71-86GHz. Research now explores the next generation of wireless systems, these operating between 100-340GHz. Such systems can support massive spatial multiplexing in both endpoint and backhaul links, and will require high-frequency transistors in VLSI and in III-V technologies, phased-array transceiver front-ends, and complex silicon RF ICs to form and aim multiple beams and to null or equalize multipath interference. We will summarize THz transistor design, IC development from 100-1000 GHz, and array and system design.

NYU Abu Dhabi ECE Faculty Candidate Seminar: Machine Learning and Swarm Decomposition: New approaches of Human Behavioral Modeling in Bullying, Depression, Parkinson’s early detection and Baby Crying Translation

Speaker: Leontios J. Hadjileontiadis, NYUAD
Time: 11:00 am - 12:00 pm Oct 15, 2018
Location: 2 MTC Room 10.099, Brooklyn, NY

Abstract: Machine Learning (ML) is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. While many ML algorithms have been around for a long time, the ability to automatically apply complex mathematical calculations to big data – over and over, faster and faster, deeper and deeper – is a recent development, leading to the realization of the so called Deep Learning (DL). The latter has an intuitive capability that is similar to biological brains. It is able to handle the inherent unpredictability and fuzziness of the natural world. In this seminar, the main aspects of ML and DL will be presented and the focus will be placed in the way they are used to shed light upon the Human Behavioral Modeling. In this effort, a new data decomposition approach based on swarm analysis will be presented and its combination with DL will be explored for the case of brain responses to bullying incidence stimuli within immersive environments. In addition, ML-based approaches will be presented for identifying fine-motor skills deterioration due to early Parkinson’s and depression symptoms reflected in the keystroke dynamics, while interacting with a smartphone, along with baby crying translation via ML-based pattern recognition. Finally, a wider perspective of the current research and future plans will conclude the seminar.

Modern Artificial Intelligence Seminar Series: The Blessings of Multiple Causes

Speaker: David Blei, Columbia University
Time: 11:00 am - 12:00 pm Oct 29, 2018
Location: 370 Jay Seminar Room 201, Brooklyn, NY

Abstract: Causal inference from observational data is a vital problem, but it comes with strong assumptions.  Most methods require that we observe all confounders, variables that correlate to both the causal variables (the treatment) and the effect of those variables (how well the treatment works).  But whether we have observed all confounders is a famously untestable assumption.  We describe the deconfounder, a way to do causal inference from observational data with weaker assumptions that the classical methods require.

How does the deconfounder work?  While traditional causal methods measure the effect of a single cause on an outcome, many modern scientific studies involve multiple causes, different variables whose effects are simultaneously of interest. The deconfounder uses the multiple causes as a signal for unobserved confounders, combining unsupervised machine learning and predictive model checking to perform causal inference.

We describe the theoretical requirements for the deconfounder to provide unbiased causal estimates, and show that it requires weaker assumptions than classical causal inference. We analyze the deconfounder's performance in three types of studies: semi- simulated data around smoking and lung cancer, semi-simulated data around genomewide association studies, and a real dataset about actors and movie revenue. The deconfounder provides a checkable approach to estimating close-to-truth causal effects. This is joint work with Yixin Wang (Full Paper).

Circuits: Terahertz (THz) and Beyond Seminar Series: Enabling the Third Wireless Revolution through Transformative RF/mmWave Circuits, Wireless Systems and Sensing Paradigms

Speaker: Harish Krishnaswamy, Columbia University
Time: 11:00 am - 12:00 pm Nov 7, 2018
Location: 370 Jay Seminar Room 1201, Brooklyn, NY

Abstract: Over the past 30 years, we have reaped the benefits of two wireless communication revolutions, which have had significant social and economic impact. The period from 1990-2000 saw the mobile wireless communication revolution, as cellular mobile telephony enabled human beings across the globe to be instantly connected with each other. The period from 2000 to the present day is witness to the mobile wireless data revolution, as 3G and 4G networks have brought the Internet to our fingertips. However, as massive as the amount of data that exists on the Internet is, it pales in comparison to the amount of data inherently present in the constitution of our physical world. The next wireless revolution will be the mobile wireless-reality revolution, which will bring the physical world to our fingertips. RF, mmWave and terahertz communication, imaging and sensing devices will enable us to interrogate the physical world and create virtual or augmented worlds in ways that exceed and augment human sensory situational awareness. The wireless-reality revolution will require a quantum leap forward in our ability to control and manipulate the RF-to- THz electromagnetic spectrum, and in our ability to transmit, acquire, aggregate and process the associated data.

I will describe recent research on high-power and energy-efficient millimeter-wave power amplifiers, transmitters and large-scale phased arrays that have drawn interest for next-generation 5G cellular networks. I will also describe recent work on extreme-bandwidth (>20Gbps) communication links at millimeter-waves for applications such as virtual and augmented reality. I will also briefly cover other novel wireless communication paradigms, including massive MIMO and full-duplex wireless, that enable extremely-high spectral efficiencies and data rates at lower RF frequencies. I will also talk about ongoing efforts towards the realization of city-scale testbeds that deploy advanced wireless hardware supporting mmWave, massive MIMO and full-duplex operation, enabling higher-layer systems research for the first time at city scales. Finally, I will touch upon new ideas on how to converge communications, imaging and sensing, enabling city-scale communication infrastructure to be repurposed for city-scale imaging.

Jack Keil Wolf Lecture Series: Guessing Random Additive Noise Decoding (GRAND)

Speaker: Muriel Medard, MIT
Time: 11:00 am - 12:00 pm Nov 8, 2018
Location: 370 Jay Room 1201, Brooklyn, NY

Abstract: We introduce a new algorithm for Maximum Likelihood (ML) decoding based on guessing noise. The algorithm is based on the principle that the receiver rank orders noise sequences from most likely to least likely. Subtracting noise from the received signal in that order, the first instance that results in an element of the code-book is the ML decoding. For common additive noise channels, we establish that the algorithm is capacity achieving for uniformly selected code-books, providing an intuitive alternate approach to the channel coding theorem. When the code-book rate is less than capacity, we identify exact asymptotic error exponents as the block-length becomes large. We illustrate the practical usefulness of our approach in terms of speeding up decoding for existing codes.

Information and Uncertainty in Learning

Speaker: Meir Feder, Tel-Aviv University, Israel
Time: 11:00 am - 12:00 pm, Nov 9, 2018
Location: 2MTC Room 10.099, Brooklyn, NY

Abstract: An information theoretical approach to learning is presented following the universal prediction/universal coding paradigms developed in the 90's. This approach leads to learning schemes that are more stable and have precise optimality criteria, as compared to the standard approach based on empirical risk minimization (ERM) and stochastic gradient (SGD). The comparison and advantages are shown on a variety of learning models from basic linear regression to deep neural networks (DNN), demonstrating the utility of proper information extraction from the training data to better learning. One of the main strengths of this approach is a measure of learnability or uncertainty in the predictive power of learning. The approach provides an information theoretic learnability measure that depends on the specific training examples and the specific test features. We demonstrate how this measure let the learner know when it does not know. The main results presented are for supervised learning. Towards the end of the talk we will also discuss unsupervised learning, active learning, model class selection and the ability to use large or union of model classes in a hierarchical universality fashion.

Circuits: Terahertz (THz) and Beyond Seminar Series: Channel measurements above 100 GHz

Speaker: Daniel M. Mittleman, Brown University
Time: Nov 15, 2018
Location: 370 Jay Room 1201 Auditorium, Brooklyn, NY

Harish

Abstract: To accommodate the rapid increase in global wireless traffic, which will reach to 49 exabytes per month by 2021, wireless networks operating beyond 95 GHz will be required. The operation and characteristics of such networks are quite different from those of conventional wireless systems, or even of 5G systems which will employ millimeter-wave links at lower frequencies. The distinctions arise from the much shorter wavelength, which implies both a significantly higher directionality and a very different propagation and diffraction characteristic. This offers both challenges and opportunities for future networks operating at these frequencies. In this presentation, we discuss several new measurements to characterize aspects of these high-frequency channels, including non-line-of-sight links. A first study of the implications of high directionality on eavedropping and physical-layer security will also be described.

Reservoir Computing with Random Skyrmion Fabrics

Speaker: Daniele Pinna, Johannes Gutenberg University, Germany
Time: 3:00pm - 4:00pm Nov 27, 2018
Location: 2MTC 10.099, Brooklyn, NY

Abstract: The topologically protected magnetic spin configurations known as skyrmions offer promising applications due to their stability, mobility and localization. Thanks to their many nanoscale properties, skyrmions have been shown to be promising in many applications ranging from non-volatile memory and spintronic logic devices, to enabling the implementation of unconventional computational standards such as Stochastic computing and Reservoir Computing. Particularly, Reservoir Computing is a type of recursive neural network commonly used for recognizing and predicting spatio-temporal events. Its basic functioning does not require any knowledge of the reservoir topology or node weights for training purposes and can therefore utilize naturally existing networks formed by a wide variety of physical processes.

 

Daniele

 

In this talk we will discuss how a random skyrmion``fabric'' composed of skyrmion clusters embedded in a magnetic substrate can be effectively employed to implement a functional reservoir (see Figure). This is achieved by leveraging the nonlinear resistive response of the individual skyrmions arising from their current dependent anisotropic magneto-resistance effect (AMR). Complex time-varying current signals injected via contacts into the magnetic substrate are shown to be modulated nonlinearly by the fabric's AMR due to the current distribution following paths of least resistance as it traverses the geometry. By tracking resistances across multiple input and output contacts, we show how the instantaneous current distribution effectively carries temporally correlated information about the injected signal. This in turn allows us to numerically demonstrate simple pattern recognition. We argue that the fundamental ingredients for such a device to work are threefold: i) Concurrent probing of the magnetic state; ii) stable ground state when forcings are removed; iii) nonlinear response to input forcing. Whereas we demonstrate this by employing skyrmion fabrics, the basic ingredients should be general enough to spur the interest of the greater magnetism and magnetic materials community to explore novel reservoir computing systems.

Daniele

About the Speaker: Thermal noise is typically regarded as nuisance when designing new device technologies. More so in nanomagnetic applications where it can lead to degraded device performance through device volatility and memory loss. In precise circumstances, however, the random variability guaranteed by thermal effects can be harnessed to enable useful device behavior at high energy efficiency and low power consumption. Thermal assistance has been known to guide phenomena such as brownian ratchets and stochastic resonance. From a dynamical systems perspective, this takes place when the physical system being studied either lacks detailed balance or is tuned periodically on timescales comparable with thermal fluctuation frequencies.My research focuses both on modelling the thermal phenomena affecting spintronically driven nanomagnet dynamics and assessing how it can be controlled in the design of magnetic structures to implement novel computational tasks. As an example, the scalability and easy tunability of magnetic heterostructures make them ideal candidates for constructing dense ensembles of magnetically and electrically coupled devices. Similarly, stable magnetic solitons living on extended thin films (such as skyrmions) can serve as extremely compact nonlinear elements. Both of these properties are fundamental requirements for future analog devices capable of enacting the operating principles of neural networks and reservoir computers. My work uses both numerical micromagnetic techniques and theoretical insight to grapple underlying principles of the phenomenas I study and implement valid proof-of-concepts for real world applications.

Circuits: Terahertz (THz) and Beyond Seminar Series: Out of Many, Many: The Path towards Scalable, Integrated, mm-Wave MIMO Arrays

Speaker: Arun Natarajan, Oregon State University
Time: 11:00 am - 12:00 pm Dec 6, 2018
Location: 370 Jay Street, Room 1201 Auditorium, Brooklyn, NY

Abstract: Wireless data usage is doubling every year and network providers are projecting demand approaching 1Gb/user/day, necessitating a 1000x increase in network capacity and 100x increase in worst-case data rates with perhaps only 2x increase in available spectrum at frequencies below 3GHz. Future cellular wireless networks will evolve to higher center frequencies that provide larger available spectrum and to ultra-dense multi-user MIMO (MU-MIMO) with heterogenous cell size (macro, pico, femto) for increased spatial spectrum reuse. Therefore, scalable RF and mm-wave transceivers with 10 (user terminal) to 1000 (base station) elements operating in ad- hoc frequency-reuse scenarios are the future paradigm for wireless transceivers. Over the last 15 years, the feasibility of integrating multiple transceivers in silicon to achieve multiple-input single-output phased-array operation has been extensively demonstrated. However, MIMO transceivers that preserve all spatial degrees of freedom promise much higher data rates and support for digital multi-beam forming. Building such scalable digital-intensive MIMO radios will require energy-efficient scalable RF/mm-wave interfaces, interferer tolerance and scalable array synchronization. In this talk, I will explore these challenges and present our research on scalable efficient mm-wave antenna-IC interfaces, reconfigurable MIMO spectral/spatial/code- domain filtering and array-level clock synchronization, focusing on architectures/circuits that potentially improve upon simple scaling of single-element transceivers for MIMO arrays.

Time: 11:00 am - 12:00 pm Dec 11, 2018
Location: 370 Jay Street, Room 1201 Auditorium, Brooklyn, NY

Abstract: In this talk I will briefly describe how I became interested in science and how I almost became a professional billiards player. Following my early interests in chemistry, and my pursuit of a Ph.D. in chemistry I became fascinated with biology and read a book, “The Thread of Life” by John Kendrew that led to my becoming a molecular biologist. I will describe the research that led to the discovery of RNA splicing, which turned out to be a temporary diversion from my real interests in DNA restriction and modification. With a keen interest in sequencing DNA I became heavily involved in using computers and was a pioneer in what is now called bioinformatics. In the RM field many discoveries have been made including, most recently, some exciting findings on bacterial methylomes.
My career has spanned traditional academic research to more commercially inspired ventures. Since I now work at New England Biolabs, a for-profit company, I will describe its origins, its philosophy towards business and life, and how commercial success can fund innovative research. One theme running through my career has been a lack of respect for dogma and a keen sense of questioning everything that people tell me they already know.

About the Speaker: Dr. Richard J. Roberts is the Chief Scientific Officer at New England Biolabs, Beverly, Massachusetts. He received a Ph.D. in Organic Chemistry in 1968 from Sheffield University and then moved as a postdoctoral fellow to Harvard. From 1972 to 1992, he worked at Cold Spring Harbor Laboratory, eventually becoming Assistant Director for Research under Dr. J.D. Watson. He began work on the newly discovered Type II restriction enzymes in 1972 and these enzymes have been a major research theme. Studies of transcription in Adenovirus-2 led to the discovery of split genes and mRNA splicing in 1977, for which he received the Nobel Prize in Medicine in 1993. During the sequencing of the Adenovirus-2 genome computational tools became essential and his laboratory pioneered the application of computers in this area. DNA methyltransferases, as components of restriction-modification systems are also of active interest and the first crystal structures for the HhaI methyltransferase led to the discovery of base flipping. Bioinformatic studies of microbial genomes to find new restriction systems are a major research focus as is the elucidation of DNA methyltransferase recognition sequences using SMRT sequencing and a new approach to m5C containing recognition sequences.

ECE Special Seminar Series: Research Challenges in High Performance Integrated Systems

Speaker: Eby G. Friedman, University of Rochester
Time: 11:00 am - 12:00 pm, Dec 13, 2018
Location: 5MTC, LC400, Brooklyn, NY

Abstract: The intention of this presentation is to provide an overview of the different areas of active research focus in the high performance integrated circuit design laboratory at the University of Rochester. Each of these topics considers different aspects of the systems integration process, with a focus on physical and circuit level aspects. Emphasis is placed on those fundamental challenges in delivering performance to high speed, high complexity heterogeneous integrated systems. Technologies range from deeply scaled CMOS to emerging devices and circuits such as spintronic, photonic, and superconductive behaviors to systems platforms such as three- dimensional integration.
Delivering high quality power to on-chip circuitry with minimum energy loss is a fundamental objective of all modern integrated circuits. Power conversion and regulation resources need to be efficiently managed to supply high quality power with minimum energy loss within multiple on-chip power domains. An integrated system of hundreds of power regulators with many millions of decoupling capacitors is required, distributing the power locally to many billions of on-chip loads. Circuits, algorithms, and design methodologies are being developed to fundamentally change the manner in which power is delivered through the package and on-chip.
Three-dimensional (3-D) integration is changing the path for device scaling, supporting the delivery of multi-faceted heterogeneous systems. Techniques and methodologies are under development to better design, model, architect, and build 3-D systems. Several test circuits have also been developed to evaluate some of the key issues in 3-D systems integration such as synchronization, power delivery, and thermal effects.
Spintronic circuits have the potential to enhance CMOS in several dimensions, particularly as non-volatile memory and novel non-von Neumann structures. Several models and circuit topologies will be described and placed within a CMOS perspective.
The energy expended in server farms has become an issue of seminal significance. CMOS simply expends too much energy to scale the size and number of these farms to satisfy expected needs. An ultra-low energy technology is needed. One possible technology is superconductive single flux quantum circuits. This technology will be briefly reviewed, and novel design methodologies, algorithms, and circuit structures will be described to support the development of large scale Josephson junction based integrated systems.

Lyapunov approach to the stability of feedback interconnections of linear and nonlinear negative imaginary systems

Speaker: Ian R. Petersen, Australian National University, Australia
Time: 1:00 pm - 2:00 pm, Dec 13, 2018
Location: 6MTC, RH304, Brooklyn, NY

Abstract: Negative imaginary systems theory allows for the design of robust controllers for flexible structures with force actuators and position sensors. The main stability result in this theory shows that the positive feedback interconnection of a negative imaginary system and a strictly negative imaginary system will be stable provided a certain DC gain condition is satisfied. We present a new Lyapunov proof of this result and then use this to extend the result into the realm of nonlinear systems, introducing nonlinear versions of the negative imaginary and strictly negative imaginary properties.
