Title:Flavorful Leptogenesis and Collider Signals

Abstract:

Low-scale leptogenesis provides a unique opportunity to test the connection between two beyond the Standard Model phenomena, namely, neutrino mass and baryon asymmetry of the universe. We will elucidate this connection in the context of TeV-scale seesaw models with discrete flavor symmetries, in which case, the Dirac Yukawa couplings are completely dictated by the low-energy neutrino mixing parameters and the heavy neutrino masses. This scenario predicts distinctive correlated features in CP and lepton number/flavor violating observables, which could be used to probe this scenario at the high-energy frontier.

Title:Neutrino as a Gateway to New Physics

Abstract:

Neutrinos have played a crucial role in our understanding of the Universe. In particular, the discovery of neutrino oscillations has provided a concrete evidence for the existence of some new physics beyond the Standard Model. However, given the lack of information on the exact nature of the underlying new physics, it is crucial to take a broader, coherent approach by exploring possible connections with other empirically-supported clues. To this end, we will discuss a synergistic study using the neutrino portal at three interrelated frontiers of fundamental physics. The complementarity between various high and low-energy observables makes this study extremely useful, irrespective of the final outcome of the ongoing direct searches for new physics at the Large Hadron Collider.

Title:Quantifying UV Degradation at the Carbon Fiber-Matrix Interphase using AFM Indentation

Abstract:

This talk presents recent results on studies conducted to investigate the effects of ultraviolet (UV) exposure of composite materials.  Ultraviolet radiation causes photocatalytic degradation in polymers leading to material degradation.  While numerous studies have been done to characterize the effects of UV exposure on the macro-scale properties of bulk polymers and composite materials, the effects of UV degradation on the interphase and in near-fiber regions are not clearly understood.

In this work we implement AFM indentation based force-mapping to investigate the effect of UV exposure on the interphase region of carbon fiber composites.  Samples exposed to ultraviolet (UV) chamber for 24 hours at 0.68 W/m2/nm irradiance at 340 nm and 60oC.  Force mapping was used to generate “full-field” load-displacement indentation curves, which were then analyzed using the Oliver–Pharr model to determine elastic modulus.  In this manner it was possible to create 32×32 and 64×64 arrays of elastic modulus values in the interphase region and the near-fiber region.  For neat CFRP sample and interphase region of thickness 100–200 μm was observed.  While for UV exposed samples a distinct interphase region was not observed.  This is attributed to the increase in chemical cross-linking of the epoxy resin due to UV exposure around the carbon fiber.  The presentation concludes with an overview of research activities and capabilities at the Helmerich Research Center and discusses areas of possible collaboration.

Note: The traditional student-speaker chat will begin in Physical Sciences Room 147 at 3:00 PM. All students are welcome! Refreshments will be served.

Title:After the Ice Bucket: Thawing Amyotrophic Lateral Sclerosis with Predictive Medicine

Abstract:

The prolific 2014 ALS Association’s Ice Bucket Challenge commenced the world-wide dumping of ice water on the heads of courageous supporters to bring awareness and research funding to a lesser-known yet fatal neurodegenerative disease, Amyotrophic Lateral Sclerosis (ALS).  The Laboratory for Pathology Dynamics at Georgia Tech, which proudly dunked GT President Peterson during the GT ALS Ice Bucket Challenge, has been actively developing data analytics, informatics, and complex systems-based techniques to expedite preclinical and clinical ALS research.  In short, we are vigorously stitching together a comprehensive quilt of ALS using thousands of data sets collected from cells, transgenic animal models, and patients.  We will discuss how predictive medicine is revealing ALS etiological underpinnings and diagnostic markers; identifying epidemiological ALS patient commonalities; precisely forecasting survival in highly heterogeneous ALS populations; identifying future disease dynamics-based combination therapies in preclinical ALS animal models; and optimizing current ALS life-prolonging interventions.  Finally, we will also discuss the application of the lab’s techniques to other research topics.

Title:Research Imaging Facility in OUHSC for Drug and Formulation Development

Abstract:

According to the Critical Path Initiative of FDA and NCI, development of imaging biomarkers is vital in addressing the expedited and cost-effective development of new drugs. The Research Imaging Facility (RIF) is the first public facility in Oklahoma to provide molecular imaging capability for research. At present, the RIF provides positron emission tomography (PET), single photon emission tomography (SPECT), and X-ray computed tomography (CT) imaging services. In addition, a dedicated low energy cyclotron is available to produce positron-emitting radionuclides for synthesis of radiopharmaceuticals. These equipment are leveraged by biomedical researchers in OUHSC as well as investigators in Oklahoma to hasten pre-clinical phase in the development of therapeutic or diagnostic agents.

With an overall objective of engendering cross-institution collaboration, the presenter(s) of this seminar will introduce the audience to nuclear imaging in general and our service capabilities in particular. In one instance, we have applied molecular imaging to answer critical developmental questions about artificial oxygen carriers. We use PET and SPECT to demonstrate that nano-particulate liposome-encapsulated hemoglobin (LEH) circulates in the body for a prolonged duration, carries oxygen in blood, and delivers oxygen to the brain for improved cerebral metabolism. Further applications of nuclear imaging and radiochemistry in drug development will be shared.

Title:Health Physics in Aerospace Environments

Abstract:

Ionizing radiation exposure is a known source of health risks. Besides the shipment of radioactive materials, there are other natural sources of ionizing radiation that must be considered such as solar and galactic cosmic radiation. Measurements of doses from these radiations are insufficient to build empirical models that meet current operational needs, and massive deployment of good quality instruments on aircraft is considered impractical. In addition to dosimetry issues, modeling the cosmic radiation environment in the atmosphere is a complex problem. While predominantly protons, cosmic ray primaries of other elements occur at fluences that cannot be neglected if calculations are to be reasonably accurate. Over the past three decades the FAA’s Radiobiology Research Team has used the deterministic radiation transport software LUIN and more recently the Monte Carlo radiation transport software MCNPX to build software (called CARI) to calculate flight doses and evaluate solar proton events. The two approaches are compared in terms of limitations and advantages.

Title:Non-Euclidean Virtual Reality

Abstract:

The properties of euclidean space seem natural and obvious to us, to the point that it took mathematicians over two thousand years to see an alternative to Euclid’s parallel postulate. The eventual discovery of hyperbolic geometry in the 19th century shook our assumptions, revealing just how strongly our native experience of the world blinded us from consistent alternatives, even in a field that many see as purely theoretical. Non-euclidean spaces are still seen as unintuitive and exotic, but with direct immersive experiences we can get a better Intuitive feel for them. The latest wave of virtual reality hardware, in particular the HTC Vive, tracks both the orientation and the position of the headset within a room-sized volume, allowing for such an experience. We use this nascent technology to explore the three-dimensional geometries of the Thurston/Perelman geometrization theorem. This talk focuses on our simulations of H3 and H2×E.
