Speaker: Heng Yin, Syracuse University
Talk Title: A Semantics-Centric Approach to Fight Android Malware
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
The number of new Android malware instances has grown exponentially in recent years. McAfee reports that 2.47 million new mobile malware samples were collected in 2013, which represents a 197% increase over 2012. Greater and greater amounts of manual effort are required to analyze the increasing number of new malware instances. This has led to a strong interest in developing methods to automate the malware analysis process. In this talk, I will present a series of semantics-centric techniques to fight Android malware. First of all, we need a powerful analysis framework to quickly understand the inner-working of a given malware sample. To this end, we developed a virtualization-based analysis framework called DroidScope, which can seamlessly reconstruct both OS and Java level semantic views to provide a holistic view of a malware attack. Moreover, we need to automatically classify malware samples by their functionalities and behaviors and discover zero-day malware. We proposed a new semantics-based technique for malware classification, by capturing the semantics-level behavior of an app in form of ``Weighted Contextual API Dependency Graphs". Then by computing the similarity between these graphs, we can accurately and reliably detect malware variants and zero-day malware. Furthermore, we believe that malware detection can be more effective by getting end users into the loop. In particular, we developed a new technique that can automatically generate human-readable descriptions of a given app, such that any unexpected descriptions will cause suspicions and flagged by end users. To encourage wide adoption and follow-up research, these research products are available in form of source code release and/or web services.
Biography: Heng Yin is an Associate Professor in the department of Electrical Engineering and Computer Science at Syracuse University. His research interests mainly lie in computer security. In particular, he is interested in applying program analysis techniques and virtualization techniques to improve software and system security and defeat malware attacks. He earned his PhD degree in Computer Science from the College of William and Mary in July 2009. He was a main contributor in BitBlaze team at UC Berkeley before joining Syracuse University. In 2011, he received NSF Career award.

Talk Title: Ultrafast and Nanoscale Interfacial Charge Transport and It's Interaction with Electomagnetic Waves
Abstract: Interfacial charge and energy transport is of fundamental importance to nanoscience and devices. It is critical to the development of quantum plasmonic junctions, ultrafast photoelectron sources, and compact electromagnetic radiation sources (millimeter wave to THz to x-ray), which have applications in imaging, communication, energy, and security. The rapid development in nanotechnology and ultrafast laser optics has opened up great opportunities to control interfacial transport at ultrashort spatiotemporal scales and offers unprecedented scientific advances. However, the understanding of the underlying physics is limited and scaling laws are largely unexplored.
In this talk, I will present recent advances on the modeling of electron transport at contact interfaces and ultrafast electron emission from metal surfaces. Scaling laws for electrical contact resistance between dissimilar materials are constructed for a large range of material properties and geometrical aspect ratios. Spreading resistance and current crowding effects are quantified from the exact solutions constructed. Validated against numerical codes, they are recently applied to electrically pumped nanolasers. A general theory is developed for the quantum tunneling current in a nanoscale metal-insulator-metal junction, covering the direct tunneling, field emission, and space-charge-limited regimes. I will also show our recent theory for laser-induced electron emission, by solving the time-dependent Schrödinger equation exactly, for arbitrary combination of dc bias and laser intensity. Other modeling efforts on geometric diodes, electromagnetic power absorption, and THz Smith-Purcell radiation will be highlighted. Future research prospects on these topics will be discussed.
Biography: Peng Zhang is an Assistant Research Scientist in the Department of Nuclear Engineering and Radiological Sciences at the University of Michigan (UM) at Ann Arbor, where he received his Ph.D. degree in 2012. He was a recipient of the UM Richard and Eleanor Towner Prize for Outstanding Ph.D. Research, the UM Rackham Presidential Fellowship Award, and the IEEE Nuclear and Plasma Sciences Graduate Scholarship Award. He has authored journal publications on electrical contacts, classical, ballistic, and quantum diodes, electron emission, electromagnetic heating phenomenology on rough surfaces, surface flashover and discharge, high power microwave sources, pulsed power systems, z-pinches, quantum electrodynamic laser-plasma interaction, and Smith-Purcell radiation. His current research interests mainly focus on theoretical and computational nanoscience and devices, including quantum plasmonic junctions, ultrafast photoemission, and novel compact electromagnetic radiation sources.

CS Colloquium: Joseph Bonneau (Stanford) - Cryptographic transparency
Tue, Feb 09, 2016 @ 11:00 AM - 12:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Joseph Bonneau, Stanford
Talk Title: Cryptographic transparency
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
Traditionally, cryptography aims to eliminate trusted authorities and reduce security to computational assumptions: the system is secure as long as attackers can't guess a random key or solve a hard mathematical problem. This talk will discuss an alternate approach: retain centralized authorities but use cryptography to provide transparency that they are behaving correctly. I'll present two examples: ensuring a public key server is serving keys consistently and ensuring a Bitcoin exchange controls enough funds to be solvent. Reasoning about the security of these systems require a more holistic approach, modeling user actions and economic incentives.
Biography: Joseph Bonneau is a Postdoctoral Researcher at Stanford University and a Technology Fellow at the Electronic Frontier Foundation. His research focuses on cryptography and security protocols, particularly how they interact with human and organizational behavior and economic incentives. Recently he has focused on Bitcoin and related cryptocurrencies and secure messaging tools. He is also known for his work on passwords and web authentication. He received a PhD from the University of Cambridge under the supervision of Ross Anderson and an BS/MS from Stanford under the supervision of Dan Boneh. Last year he was as a Postdoctoral Fellow at CITP, Princeton and he has previously worked at Google, Yahoo, and Cryptography Research Inc.

Communications, Networks & Systems (CommNetS) Seminar
Wed, Feb 10, 2016 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Reinhard Heckel, UC Berkeley
Talk Title: Super-resolution radar
Series: CommNetS
Abstract: In this talk, we study the identification of a time-varying linear system whose response is a weighted superposition of time and frequency shifted versions of the input signal. This problem arises in a multitude of applications such as wireless communications and radar imaging. Due to practical constraints, the input signal has finite bandwidth B, and the received signal is observed over a finite time interval of length T only. This gives rise to a time and frequency resolution of 1/B and 1/T. We show that this resolution limit can be overcome, i.e., we can recover the exact (continuous) time-frequency shifts and the corresponding attenuation factors, by solving a convex optimization problem. This result holds provided that the distance between the time-frequency shifts is at least 2.37/B and 2.37/T, in time and frequency. Furthermore, this result allows the total number of time-frequency shifts to be linear (up to a log-factor) in BT, the dimensionality of the response of the system. More generally, we show that we can estimate the time-frequency components of a signal that is S-sparse in the continuous dictionary of time-frequency shifts of a random (window) function, from a number of measurements, that is linear (up to a log-factor) in S. We also discuss extensions of this theory to the localization of targets in MIMO radar.

CS Colloquium: George Varghese (Microsoft Research) -From EDA to NDA: Treating Networks like Hardware Circuits
Thu, Feb 11, 2016 @ 11:00 AM - 12:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: George Varghese, Microsoft Research
Talk Title: From EDA to NDA: Treating Networks like Hardware Circuits
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
Surveys reveal that network outages are prevalent, and outages take hours to resolve, resulting in significant lost revenue. We suggest fresh approaches based on verification and synthesis.
First, I show how to exploit physical symmetry to scale network verification for large data centers. While Emerson and Sistla showed how to exploit symmetry for model checking in 1996, they exploited symmetry on the logical Kripke structure. We factor the symmetries into symmetries on headers and symmetries on the physical topology.
I will then describe work we have done in synthesis. I will set the stage by describing a reconfigurable router architecture called RMT and an emerging language for programming routers called P4 (that promises to extend the boundaries of Software Designed Networks). I will then describe two synthesis efforts for flexible routers, one akin to register allocation (table layout) and one akin to code generation (packet transactions). I will focus especially on code generation and show that the all-or-nothing compilation required for wire-speed forwarding requires adapting standard compiler techniques.
These results suggest that concepts from Electronic Design Automation (EDA) can be leveraged to create what might be termed Network Design Automation (NDA). I end by briefly exploring this vision. This is joint work with collaborators at Edinburgh, MSR, MIT, Stanford, and University of Washington.
Biography: George Varghese received his Ph.D. in 1992 from MIT. From 1993-1999, he was a professor at Washington University, and at UCSD from 1999 to 2013. He was the Distinguished Visitor in the computer science department at Stanford University from 2010-2011. He joined Microsoft Research in 2012. His book "Network Algorithmics" was published in December 2004 by Morgan-Kaufman. In May 2004, he co-founded NetSift, which was acquired by Cisco Systems in 2005. With colleagues, he has won best paper awards at SIGCOMM (2014), ANCS (2013), OSDI (2008), PODC (1996), and the IETF Applied Networking Prize (2013). He has won lifetime awards in networking from the EE (Kobayashi Award) and CS communities (SIGCOMM) in 2014.

Band-Engineered Complex Oxide Interfaces: New Insights and Opportunities

Speaker: Professor Bharat Jalan, University of Minnesota
Talk Title: Band-Engineered Complex Oxide Interfaces: New Insights and Opportunities
Series: Graduate Seminar
Abstract: Complex oxide heterostructures can show strong correlation effects, novel magnetism, high breakdown voltage, and high 2D electron density (of the order of 1014 cm-2), unattainable in traditional semiconductor heterostructures. High 2D electron densities are of particular interest for studying low-dimensional physics in narrow d-band materials, in addition to fabricating novel plasmonic field-effect devices (FETs). Recent advances in thin film growth approaches have enabled the growth of this material class in thin film and heterostructure forms with pristine structural quality (similar to that of the conventional semiconductors). However the grand challenge in the field is to obtain these materials with the high level of stoichiometric and defect control. In this talk, I will present my groups effort to address these challenges and to utilize intrinsic defects as a new degree of freedom to control materials electronic and magnetic property using the hybrid molecular beam epitaxy (MBE) approach. In particular, I will discuss the role of intrinsic defects in realizing and tailoring the 2D electron gas at perovskite oxide heterojunctions.
I will then present a novel approach for creating high-density 2DEGs at perovskite heterojunction using internal charge transfer. 2D carrier density much higher density than expected based on resolution of the polar discontinuity at perovskite oxide heterojunctions can be achieved via internal charge transfer using band-engineered interfaces. Combining DFT modeling and experiments using x-ray photoelectron spectroscopy, scanning transmission electron microscopy, electron energy loss spectroscopy, energy dispersive x-ray spectroscopy and electronic transport measurements, I will discuss the origin of these carriers, dimensionality and transport mechanisms. Finally, I will discuss how electron and hole doping via band-engineered approaches can be achieved, which may provide an exceptional route to revisit the electronic phase diagrams of transition metal oxides in the clean doping limit.

Speaker: Dr. Michael Friedlander, UC Davis
Talk Title: Level-set methods for convex optimization
Series: CommNetS
Abstract: Convex optimization problems in a variety of applications have favorable objectives but complicating constraints, and first-order methods are not immediately applicable. We propose an approach that exchanges the roles of the objective and constraint functions, and instead approximately solves a sequence of parametric problems. We describe the theoretical and practical properties of this approach for a broad range of problems, including low-rank semidefinite optimization problems.
Joint work with A. Aravkin, J. Burke, D. Drusvyatskiy, S. Roy.

Talk Title: Thixotropy of Fresh Cement-Based Systems
Abstract: Over its lifetime, cement-based materials transition from behaving as a near-Newtonian fluid to a viscoelastic fluid-solid to eventually a rock-like solid. And although the first two phases are fleeting compared to the third phase, this earlier life period is intimately tied to materials processing.
Therefore the corresponding properties are critical in determining the efficiency of the placement process during construction, as well as the eventual performance of the structure in place. This requires that the rheological properties of the material be well characterized and controlled. During placement the material undergoes a wide range of deformations -“ very large during processes such as pouring and pumping, but then diminishingly small after placement when it is essentially at rest. This talk will cover studies that investigate the specific rheological aspect of thixotropy in cement paste and mortar systems that incorporate highly-purified attapulgite clay through static shear and dynamic rheological protocols that span wide timescales and magnitudes of deformations and rates.
Biography:
Shiho Kawashima is an Assistant Professor of Civil Engineering and Engineering Mechanics at Columbia University. Her work is in experimental cement and concrete research, which aims to tie nano-microstructural behavior to macroscale structural response. She specializes in cement rheology, particularly in the development of innovative measurement techniques to further the understanding of the structural and temporal evolution of the fresh-state microstructure of cementitious systems. She is also interested in the design of nanocomposites and sustainable infrastructural materials. She received her B.S. in Civil Engineering and Engineering Mechanics at Columbia University, and her M.S. and Ph.D. in Civil Engineering at Northwestern University.

Multi-scale integration and modularity in complex dynamical systems

Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Artemy Kolchinsky, Santa Fe Institute
Talk Title: AI Seminar-Multi-scale integration and modularity in complex dynamical systems
Series: Artificial Intelligence Seminar
Abstract: I will discuss two novel approaches to studying distributed organization in complex dynamical systems. In the first [1], we define an information-theoretic measure of the strength of integration at multiple scales, where scale is defined according to an underlying distance metric. We show that our method generalizes several existing complexity measures and is tractable to compute. As demonstrated on human resting state fMRI time-series data, it also captures important aspects of integration in network- and spatially-embedded systems.
In the second approach [2], we address modularity, a pattern of organization in which a system is composed of weakly-coupled subsystems. We develop a technique to decompose dynamical systems based on the idea that modules constrain the spread of perturbations. The method captures variation of modular organization across different system states, time scales, and in response to different kinds of perturbations. It also offers a principled alternative to community detection applied to statistical-dependency networks (e.g. correlation matrices or "functional networks").

Talk Title: Feeling Pericellular Mechanical Heterogeneities
Abstract: While there is strong evidence for roles of bulk stromal stiffness in cell regulation, roles for the pericellular mechanical microenvironment are less clear, in large part due to the difficulty of measurement. My group implements automated Active Microrheology (aAMR), an optical tweezers technology, to probe extracellular stiffness and map it in the volume surrounding cells. Our aAMR applies sinusoidal optical forces onto microbeads embedded within natural extracellular matrices (ECMs), including those comprised of fibrin and type 1 collagen. As in the case of passive microrheology, aAMR reports the complex material response function of the ECM just surrounding each microbead. Different from passive methods, aAMR is valid for systems not in thermal equilibrium, as is typical for regions of the ECM near to contractile cells. Our aAMR microscope can probe many beads surrounding each cell to map the mechanical landscape, allowing us to seek correlations between local stiffness distributions and cell properties such as contractility, signaling, and differentiation. I will present specific examples for which the distribution of pericellular stiffness correlates with cell phenotype/state including: MT1-MMP deficient mesenchymal stem cells, human aortic smooth muscle cells with compromised contractility and fibrosarcoma cells cultured in type 1 collagen gels.
Biography: My research program has two areas of focus: mechanobiology and medical device development. My research group uses photonic tools to investigate roles for mechanical forces and physical properties in the regulation of tissues. We have expertise in the areas of photonics, laser ablation, imaging, tissue engineering and mechanobiology. Specifically, we develop instrumentation and devices for quantitative biophysical measurements towards the study of single molecule biophysics and cell-tissue physical interactions. In particular, we use optical tweezers to measure single receptor-ligand interactions and have discovered strong evidence for the role of ligand-endocytic forces in the activation of the Notch receptor. We also use optical tweezers/scissors to measure local continuum viscoelastic parameters in order to seek correlations between microenvironment mechanics and cell function. We have applied these tools to test mechanical hypotheses in the areas of cancer biology, microvascular morphogenesis, tissue engineering, stem cell biology and the transition of ductal carcinoma in situ into an invasive phenotype.

Talk Title: Analog and Stochastic Computation in Living Cells and Supercomputing Chips
Abstract: Despite more than 15 years of research, synthetic circuits in living cells have been largely limited to a handful of digital logic gates and have not scaled. We show that one important reason for this failure to scale is an overemphasis on digital abstractions rather than on recognizing the true noisy, analog, and probabilistic nature of biological circuits. We show that synthetic and natural DNA, RNA, and protein circuits in cells must use analog, collective analog, probabilistic, and hybrid analog-digital computational approaches to function; otherwise, even relatively simple computations in cells will exceed energy, molecular-count, and cellular-resource budgets.
Analog circuits in electronics and molecular circuits in cell biology are also deeply connected: There are astounding similarities between the equations that describe noisy electronic flow in subthreshold transistors and the equations that describe noisy molecular flow in chemical reactions, both of which obey the laws of exponential thermodynamics. Based on these similarities, it is possible to take a principled approach to design circuits in living cells. For example, we have engineered logarithmic analog computation in living cells with less than three transcription factors, almost two orders of magnitude more efficient than prior digital approaches to create a "bio-molecular slide rule". In addition, highly computationally intensive noisy DNA-protein and protein-protein networks can be rapidly simulated in mixed-signal supercomputing chips that naturally capture their noisiness, dynamics, and non-modular interactions at lightning-fast speeds. Such an approach may enable large-scale design, analysis, simulation, and measurement of cells to be more precise and robust than it is today. To realize the promise of synthetic biology and systems biology for medicine, biotechnology, agriculture, and energy, we will need to go back to the future of computation and design and implement circuits via a collective analog approach like Nature does. We must also exploit and develop existing analog and mixed-signal electronic design tools for enabling biological design to scale.

Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Thang Luong, Stanford University
Talk Title: Recent Advances in Neural Machine Translation
Series: Natural Language Seminar
Abstract: Neural Machine Translation (NMT) is a simple new architecture for getting machines to learn to translate. At its core, NMT is a single big recurrent neural network that is trained end-to-end with several advantages such as simplicity and generalization. Despite being relatively new, NMT has already been showing promising results in various translation tasks. In this talk, I will give an overview of NMT and highlight my recent work on (a) how to address the rare word problem in NMT, (b) how to improve the attention (alignment) mechanism, and (c) how to leverage data from other modalities to improve translation.
Biography: Thang Luong is currently a 5th-year PhD student in the Stanford NLP group under Prof. Chris Manning. In the past, he has published papers on various different NLP-related areas such as digital library, machine translation, speech recognition, parsing, psycholinguistics, and word embedding learning. Recently, his main interest shifts towards the area of deep learning using sequence to sequence models to tackle various NLP problems, especially neural machine translation. He has built state-of-the-art (academically) neural machine translation systems both at Google and at Stanford.
