Speech Title: "Bio-Mimetic Sensing with Multiple Sensors"
Abstract: We revisit the visual sensor pointing control problem as a constrained dynamics on SO(3) from the point of view of a nonlinear multi input multi output (MIMO) system. The attitude of every sensor is assumed to satisfy a constraint, such as the ones proposed by Donders and Listing for the monocular and binocular eyes and the head rotation problems. While studying the problem of controlling the pointing direction of human head, the constraint, proposed by Donders, is that for every human head rotating away from its primary pointing direction, the rotational vectors are restricted to lie on a surface called the Donders' surface. In this talk we assume the existence of Donders' surfaces for an array of visual sensors in a flock, tasked with the goal of tracking a point target in the visual space. We assume that the Donders' surfaces are described by a quadratic equation on the coordinates of the rotation vector. The inputs to the MIMO system are three external torque triplet, one for each visual sensor. The three output signals from each sensor are chosen as follows. Two of the signals are coordinates of the frontal pointing direction. The third signal measures deviation of the state vector from the Donders' surface. Thus we have a square system and recent results have shown that this system is feedback linearizable on a suitable neighborhood of the state space. We estimate a lower bound on the size of this neighborhood, by computing distance between the Donders' and the associated Singularity surface. Our results are discussed for the monocular, binocular and the trinocular cases and a comparison is made from the point of view of the observed singularities. Analysis of the feedback linearizing control problem, from the point of view of `three eyed visual sensing', is new.

Speech Title: "Innovative Graph-Based Tools for Big Data Analytics in Bioinformatics"
Abstract: With continuous advancements of biomedical
instruments and the associated ability to collect diverse types of valuable
biological data, numerous research studies have been recently focused on how
to best extract useful information from the ‘Big Data’ currently available.
The currently available data is not only massive in size, but it also
exhibits all the features of complex big data systems with a high degree of
variability, veracity and velocity. How to leverage this raw data to advance
biomedical research, particularly in dealing with outbreaks and infectious
diseases, and improve health care, through personalized and targeted
medicine, can be considered the most exciting scientific challenge of our
generation. Although many analytical tools have been developed recently to
take advantage of this massive raw data, researchers are still scratching
the surface regarding what can be mined and utilized to advance biomedical
research in general and healthcare in particular. In this talk, we present
new big data analytics tools using graph modeling and network analysis along
with how to effectively utilize High Performance Computing in implementing
such tools. We demonstrate how the proposed tools can be applied to analyze
complex data and reveal new useful relationships in various case studies. We
illustrate how the graph-based tools led to new biological discoveries by
efficiently integrating heterogenous data associated with infectious
diseases, aging research and microbiome studies.

Speech Title: "Biomarker Discovery in Diagnostics: A Case Study on Premature Delivery"
Abstract: Premature delivery or Preterm birth is a major concern across the developing and developed world. It remains as the leading cause of perinatal mortality with a significant strain on healthcare costs. Risk factors and biomarkers used so far have been ineffective in identifying the majority of preterm deliveries. This study focuses on developing and validating a mass spectrometry based protein biomarker test to predict spontaneous preterm delivery in asymptomatic pregnant women. Maternal serum was processed by a proteomic workflow, and proteins were quantified by multiple reaction monitoring mass spectrometry. We evaluated a predictor composed of insulin-like growth factor binding protein 4 (IBP4) and sex hormone binding globulin (SHBG) in a clinical validation study to classify spontaneous preterm delivery cases (<370/7 weeks gestational age). The predictor had an area under the receiver operating characteristic curve value of 0.75. This early detection would guide enhanced levels of care and accelerate development of clinical strategies to prevent preterm delivery.

Speech Title: "Optimization-Based Image Reconstruction from Fast-Scanned, Noisy Projections in EPR Imaging"
Abstract: Tumor oxygen concentration image is essential to oxygen-image guided, precise radiation therapy. Electron Paramagnetic Resonance Imaging (EPRI) is an advanced oxygen imaging technique. However, the scanning time is still comparatively long, leading to motion artifacts for static imaging and low time resolution for dynamic imaging. Usually, a projection signal at a specific angle is obtained by averaging thousands of repeatedly collected projections to suppress random noise and achieve a high signal to noise ratio (SNR). Reducing the repetition times of projection collected at a specific angle may effectively speed up the whole scanning process. However, the EPR images reconstructed by the conventional three dimensional filtered backprojection (FBP) algorithm from these fast-scanned, noisy projections are too noisy to be used for further image postprocessing. In the work, we investigate the capability of an optimization-based algorithm in accurate reconstruction from noisy projections. We designed a total variation constrained, data divergence minimization (TVcDM) model, derived its Chambolle-Pock (CP) solving algorithm, and then validated and evaluated the CP algorithm via mathematical and physical phantoms. Studies show that the CP algorithm may accurately reconstruct EPR images from fast-scanned, noisy projections and thus the whole scanning process may be speeded up four times compared with the full scan time demanded by the FBP algorithm.
