Abstract: From ecosystems to the social scene at Union, to the neural network you are using to read this abstract – networks are everywhere we look. A current mystery in network science is how the individual units of a network can send and receive information to one another, while at the same time switch on and off entire portions of the network. In this talk I will focus on some recent theoretical investigations into what are known as network switches. These switches combine the non-linear dynamics at units with the connectivity of the network to gate information while at the same time process that same information. The particular focus of the talk will be brain networks where it can yield new insights into normal functions such as memory recall or disease states such as seizures. The wider view of network switches will also be discussed as it applies to the spread of rumors in social networks, the genetic control of development, and the dynamics of classroom learning.

Abstract: High resolution imaging systems are invaluable tools for biomedical research and clinical practice. Photoacoustic microscopy (PAM) is an emerging hybrid technique that can overcome the limitations of conventional optical and ultrasonic imaging modalities. A pulsed laser illuminates tissue, where optical absorption and transient thermal expansion leads to ultrasound emission. Image contrast is based on the naturally occurring (endogenous) optical absorption in tissue. Spatial resolution and penetration depth are determined by the ultrasonic properties of tissue. Performing PAM at multiple laser wavelengths can produce valuable spectroscopic information that differentiates various tissue types. The Biomedical Ultrasonics & Biophotonics Laboratory (BUBL) at Union College is developing rapidly tunable pulsed lasers for high-speed spectroscopic PAM. We are currently investigating nonlinear fiber optics, particularly stimulated Raman scattering, to produce a multi-color output from a single wavelength laser. We have demonstrated multi-color pulsed lasers operating at visible and near-infrared wavelengths for potential applications in mapping blood oxygenation in capillaries and visualizing atherosclerotic plaques.

Prof. Jenn Currey, Union College
Location: Olin 115
Abstract: Each year there are over 1 million bone fractures. Most heal without incident; however, 1 out of 20 fractures have impaired healing often requiring surgery and further treatments. One method of treating these fractures is the application low levels of mechanical stimulation via an external fixator, but what exactly are low levels? In other words, what is the precise relationship between the local mechanical environment and patterns of bone repair? We believe the answers lie in the development of a technique to accurately control and measure the mechanical stimulus applied to a healing fracture.

- May 26 Investigating Quantum Oscillations in the Thermal Coefficient of Resistivity of Ultra-thin Ag Capping Layers on Cu for IC Interconnect Applications
Abstract: As the semiconductor industry continues to scale feature sizes, scattering from phonons, surfaces, and grain boundaries result in an increase of metal interconnect resistivity in state-of-the-art integrated circuits (ICs). Manufacturable solutions to the interconnect resistivity challenges are needed for near-term integration. Previous studies of thin Ag films deposited on Cu demonstrated oscillations in the electron-phonon interactions within the bilayer system. This work investigates oscillations in the resistive properties of the Ag/Cu bilayer system and discusses the applicability of these oscillations to the resistivity challenges facing metal-based IC interconnects. Ag/Cu bilayer films were prepared by physical vapor deposition. The films were characterized by measuring the electrical resistance of the films at various temperatures and calculating the thermal coefficient of resistance (TCR) for various Ag capping layer thicknesses.
An oscillatory relationship between Ag film thickness and the TCR was observed for ultra-thin Ag films deposited on Cu. Patterned Ag-capped Cu lines were fabricated with Ag thicknesses corresponding to the thicknesses at which the TCR minima were observed in the films. The Ag- capped Cu lines exhibited resistive behavior similar to that of the Ag/Cu films.

- April 10 Acoustic cues to laryngeal and supralaryngeal articulator timing in child speech
Abstract: Acoustic studies of child speech document how child speakers use the same or different acoustic cues as adults do to signal the distinction between different speech sounds. In this study of four syllable-final stop consonants (1244 tokens of tub, bug, cup, duck) produced by 2-3 year-old children. The results show agreement with earlier studies suggesting that even early in development children produce contrastive cues similar to adults, but with exaggerated duration values for, e.g., consonant closure and vowel duration,largely due to their slower speaking rate. However, this study also revealed a striking difference between adults and children for two cues related to vocal-fold configuration: children produce more noise at the vowel/stop transition before [-voice] stops (for which the vocal folds do not vibrate), and fewer voicebars for [+voice] stops (for which the vocal folds should continue to vibrate). We suggest that these differences arise not from immature cognitive representations of the voicing contrast, for which the children already produce some adult-like cues. Rather, the children are still mastering the ability to prolong vocal-fold vibration into the [+voice] consonants. The results are consistent with a model in which children, like adults, represent individual cues to contrastive features and select among them for production of that contrast.

- Mar 06 Estimating Power System Electromechanical Modes from Synchrophasor Data
Abstract: Electric power systems exhibit low frequency oscillations associated with dynamics known as electromechanical modes. The frequency and damping of the oscillations are described by the generally complex modes, while the mode shapes define the amplitude and phasing of the oscillations throughout the power system. If the damping of a particular mode is allowed to become too low, the oscillation of the mode may grow out of control and cause a system-wide outage like the one observed by the Western Electricity Coordinating Council in 1996. Therefore, accurate estimates of the electromechanical modes are required.
This seminar focuses on a Recursive Maximum Likelihood (RML) estimator that is capable of providing estimated error bounds in addition to modal frequency and damping estimates. Currently, when power system operators are presented with real-time estimates of electromechanical modes, they have no concept of how reliable the estimates are. The RML approach ameliorates the situation by producing an estimate of the variance of the frequency and damping estimates. This is especially useful in the avoidance of false alarms, potentially saving the power system operators both time and money.

- Oct 18 Ultrahigh-Speed OCT with Microsurgical Applications
Dr. Kang Zhang, GE Global Research
Abstract: Microsurgeries, such as ophthalmologic surgery, neurological surgery, and otolaryngologic surgery, require both optical and physical access to perform surgical task on delicate tissue with micrometer accuracy. During the microsurgery, a surgeon performs activities such as visualizing targets, guiding microsurgical tools and executing on surgical targets, subject to human’s sensory and motion limits. Conventionally, visualization during the microsurgery is realized by surgical microscopes with limited depth perception of tissue microstructures, which makes the operation extremely challenging. This talk presents an interdisciplinary project involving optical imaging, optical sensing and high-performance computing conducted during the speaker’s research in Johns Hopkins University and Johns Hopkins Medical School. Here the ultrahigh speed real-time optical coherence tomography (OCT), a novel non-invasive multi-dimensional imaging modality with micrometer resolution, is utilized for microsurgical intervention.

Dr. Adam Halverson, General Electrical Global Research
Abstract: The current dominant solar photovoltaic technology is based on silicon. Due to its indirect band gap, silicon requires thick wafers for full absorption of the incident solar irradiance, and also requires extreme purity to avoid non-radiative recombination pathways which are detrimental to performance. Such extreme purity requirements significantly increase the cost to produce silicon-based photovoltaics. Several new thin-film material systems are being developed that attempt to circumvent the costs due to the purity and thickness requirements of silicon. I will discuss the roles of defects and disorder on the performance and electron dynamics in these devices. During the talk I’ll also discuss my background, education, and career.
Bio: Dr. Adam Halverson received his undergraduate degree in physics from Reed College in Portland, OR, writing a theoretical thesis on a method to linearize a particularly difficult non-linear differential equation. He then worked in the semiconductor capital equipment industry for a year before heading to the University of Oregon for graduate school in physics.

Jerry Selvaggi, PhD
Abstract: Electrical machines play an essential role in many commerical and industrial products. A solid understanding of both the theory and the application is essential to advance the improvement of such machinery. Today’s seminar will illustrate the role that modeling plays in understanding some of the more esoteric properties exhibited by rotating machines not normally discussed in a standard electric power curriculum. The talk will include the design of a new motor called the Rotating-Core Motor. This motor exhibits both a low magnetic and low acoustic signature. In some respects, one could consider this a “silent” motor.

Michael Tolley, Harvard University
Abstract: Engineered systems traditionally require highly specialized fabrication and assembly processes that are expensive and not easily adaptable. This places a large overhead burden on the development of new systems or the adaptation of existing systems to new conditions. My work addresses this challenge through the development of programmable fabrication approaches for mesoscale robotic systems. In this talk, I will describe three related research thrusts: The first is an approach to achieving programmable matter (i.e. a substance the shape and properties of which can be tuned to achieve a variety of tasks) through the stochastic fluidic assembly of mesoscale and microscale components. The second thrust, Printable Programmable Machines, is a means to achieving the rapid development and fabrication of low-cost printable robots using origami-inspired folding techniques. Finally, I will discuss recent work in the design and fabrication of soft robots which employ embodied AI to achieve complex locomotion gaits. These three examples represent a paradigm shift in robotics manufacturing towards the programmable fabrication of smart robots.

Nicholas P. Sardino, IBM
Abstract: Three years ago, IBM began describing the Smarter Planet that we saw emerging. It was a world in which industries were becoming more instrumented, interconnected, and intelligent, producing data that could be used to improve the quality of our lives and our work. Over this time, we also recognized that there was a pattern to the way that most successful institutions were approaching their IT infrastructure. They were thinking about computing in new ways—and using it to create formidable opportunities for growth and innovation…despite facing such challenges as tremendous demands for service, inflexible infrastructures, flat budgets and incomplete, unreliable data. Through a new approach we call Smarter Computing, enterprises can tackle these constraints. They can leverage all of the data in their enterprise, optimize systems for workloads and manage their IT infrastructure in a much more cloud-like fashion, for dramatically improved economics and performance. If an enterprise can think holistically about its IT infrastructure, it can implement a Smarter Computing model and gain the benefits we’ve seen with our own clients—double capacity for IT services, flat IT costs and the ability to implement new breakthrough services.
Bio: Nick has been with IBM for 8 years and is currently a subject matter expert and client presenter in the Poughkeepsie Executive Briefing Center covering topics such as Smarter Computing, System z Hardware, and Linux on System z.

Prof. Takashi Buma, Union College
Abstract: Biomedical imaging systems using light and ultrasound are attractive for their fine spatial resolution, real-time image display, and portability. This seminar describes some of the on-going efforts in the Biomedical Ultrasonics & Biophotonics Laboratory (BUBL) at Union College. Optical coherence tomography (OCT) is an emerging technology for applications in ophthalmology, dermatology, and cardiology. Cross-sectional images are obtained by laterally scanning a focused optical beam across the region of interest while using an interferometer to detect the backscattered light. Depth information is obtained by processing the interference fringes in the detected signals. Our previous work applied OCT to visualize fingertip features below the skin surface for biometric applications. A current project is a collaboration with the Department of Mechanical Engineering, where we will perform 3-D OCT imaging to help study the biomechanics of heart tube looping in a developing chick embryo. Ultrasound biomicroscopy (UBM) is a high frequency ultrasound imaging technique with applications in ophthalmology and developmental biology. Transducer arrays are required to produce fully focused images over a wide field of view. However, UBM arrays have been extremely difficult to fabricate with conventional piezoelectric technology. We are exploring highly populated sensor arrays based on optoacoustics, where ultrasound is detected with optical techniques. This project involves all aspects of the imaging system, ranging from transmitter and sensor fabrication to video-rate image reconstruction with a graphics processing unit (GPU).
Bio: Dr. Takashi Buma received his B.S.E. in Electrical Engineering with a certificate in Engineering Physics from Princeton University in 1995. He received his Ph.D. in Applied Physics from the University of Michigan in 2002, where his research in the Biomedical Ultrasonics Laboratory explored techniques to generate and receive high frequency ultrasound. He then joined the Center for Ultrafast Optical Science at the University of Michigan to perform research in time-domain terahertz imaging systems. He was an Assistant Professor of Electrical and Computer Engineering at the University of Delaware before joining Union College in the fall of 2011.

Dr. Andrew Leach, GE Global Research
Abstract: Hyperpolarization technology enables magnetic resonance imaging (MRI) to expand beyond anatomical imaging to measure the metabolism within tissue. This new capability may revolutionize the detection and treatment of disease through the measurement of changes in local cellular chemistry in its early stages. Real‐time imaging of cellular metabolism will enhance diagnostic capabilities in the fields of oncology, cardiology and neurology as well as enable personalized treatment through the measurement of patient response to therapies. This technique relies on a suite of new molecular agents based on endogenous molecules that can probe the natural metabolic pathways of human physiology.
This presentation will discuss the state‐of‐the‐art in hyperpolarization technology as well as recent developments towards the production of a polarizer system that is compatible with clinical use. Primary concerns are patient and operator safety, performance of the method, as well as operator convenience. A polarizer of novel design has been successfully built and tested. The polarizer differs from those previously used in that it is designed with capabilities required for future clinical use.

Jan 26: Digital Image Forensics: There is More to a Picture Than Meets the Eye
Dr. Siwei Lyu, University at Albany
Abstract: The past decade has witnessed remarkable advances in digital image processing and computational photography, resulting in sophisticated image-editing software systems. The ease of digital image manipulation has also posed many new challenges. In particular, digital images have become more vulnerable to malicious tampering compared to their non-digital counterparts. This circumstance galvanized rapid developments of research in digital image forensics.
In this talk, I will focus on my recent works in detecting several types of digital image tampering operations, including: a) region duplication, where regions in the same image are copied, transformed, and pasted to new locations to conceal the original image; b) image splicing, where regions from an image are pasted into a different image; and c) photographic vs. photorealistic detection, where the task is to differentiate a real photograph from an image made from computer graphics software.
The unifying theme of these techniques is to use statistical analysis of normal natural photographic image signals to show abnormalities of tampered images. I will describe the mathematical and algorithmic aspects of these methods, and demonstrate their effectiveness on realistic image forgeries.
Bio: Siwei Lyu is Assistant Professor at the Computer Science Department of the University at Albany. His scientific expertise include natural image statistics, computational visual neural science, digital image forensics, machine learning, and computer vision.

Thomas Tongue (Zomega Terahertz Corporation)
Abstract: The “Terahertz Gap” occupies a unique place in the EM spectrum as the transition from classical electrodynamics (RF, mm-wave) to quantum mechanics for both generation and detection. Recently, techniques from both the mm-wave and far-infrared have pushed to close this gap, and commercial applications for THz waves are now being actively explored. THz Time Domain Spectroscopy (TDS) is one common technique that has been applied for both non-destructive testing and material characterization at short stand-off distances. With the advent of real-time THz TDS capabilities, imaging has become an important frontier for THz applications, especially in inspection and process control. However, software algorithms and data processing for these images is still in its infancy, and represents an opportunity for further improvement in system performance. This talk will provide an overview of THz techniques, focusing on THz TDS and its application to imaging and highlighting important areas where software needs to catch up to the challenges of such information-rich data.
Bio: Thomas Tongue is a serial entrepreneur and CEO of Zomega Terahertz Corporation. His background in Physics combined with his MBA provide him with a unique perspective that bridges the technical and management aspects of running an emerging technology company.

Abstract: Facial expression recognition remains a challenging problem especially when the face is partially corrupted or occluded. I will describe a new classification method, termed Sparse Representation based Classification (SRC), that is applied to accurately recognize expressions. A test vector is representable as a linear combination of vectors from its own class and so its representation as a linear combination of all available training vectors is sparse. Efficient methods have been developed in the area of compressed sensing to recover this sparse representation. SRC gives state of the art performance on clean and noise corrupted images matching the recognition rate obtained using Gabor based features. When test images are occluded, SRC improves significantly on the performance obtained using Gabor features.
