Vesicular monoamine transporters (VMAT) are responsible for the uptake of cytosolic monoamines into synaptic vesicles in monoaminergic neurons. Two closely related VMATs with distinct pharmacological properties and tissue distributions have been characterized. VMAT1 is preferentially expressed in neuroendocrine cells and VMAT2 is primarily expressed in the CNS. The neurotoxicity and addictive properties of various psychostimulants have been attributed, at least partly, to their interference with VMAT2 functions. The quantitative assessment of the VMAT2 density by PET scanning has been clinically useful for early diagnosis and monitoring of the progression of Parkinson's and Alzheimer's diseases and drug addiction. The classical VMAT2 inhibitor, tetrabenazine, has long been used for the treatment of chorea associated with Huntington's disease in the United Kingdom, Canada, and Australia, and recently approved in the United States. The VMAT2 imaging may also be useful for exploiting the onset of diabetes mellitus, as VMAT2 is also expressed in the β-cells of the pancreas. VMAT1 gene SLC18A1 is a locus with strong evidence of linkage with schizophrenia and, thus, the polymorphic forms of the VMAT1 gene may confer susceptibility to schizophrenia. This review summarizes the current understanding of the structure-function relationships of VMAT2, and the role of VMAT2 on addiction and psychostimulant-induced neurotoxicity, and the therapeutic and diagnostic applications of specific VMAT2 ligands. The evidence for the linkage of VMAT1 gene with schizophrenia and bipolar disorder I is also discussed. © 2010 Wiley Periodicals, Inc.

Pedestrian safety continues to be a significant concern in urban communities. Several recent reports indicate that injuries and fatalities in pedestrian-related accidents are steadily rising and that pedestrian distraction is one of the leading causes in such accidents. Existing systems and techniques for improving pedestrian safety, which primarily operate on users smartphones and mobile devices in a stand-alone fashion, have several design drawbacks and performance and usability concerns that have precluded their successful adoption and usage. The goal of this project is to improve pedestrian safety by designing accurate, efficient and usable tools and techniques, which can be easily adopted by urban users.
In order to accomplish this goal, this project plans to pursue a focused research agenda involving novel technologies and several exploratory and untested ideas. As part of the proposed pedestrian safety framework, accurate and energy-efficient on-device distraction detection techniques will be developed by employing multi-sensor and heterogeneous data available from upcoming mobile and wearable devices. In this direction, supervised and semi-supervised learning will be used to design efficient activity classification and distraction prediction techniques which will be empirically evaluated using proof-of-concept implementations. Unlike existing stand-alone approaches, the proposed framework employs a connected-community approach to accurately capture the impact of both a pedestrians own actions, as well as the actions of others, on his/her safety. This involves the design and implementation of a privacy-preserving and cloud-assisted data-analytics engine to capture, analyze and notify pedestrians of impending hazardous situations from the crowd-sourced distraction data obtained from participating users. Finally, a comprehensive performance and usability evaluation will be conducted by deploying a large-scale testbed involving participants from Wichita State Universitys (WSU) campus community. The project outcomes, including the planned testbed, will have a significant impact on improving pedestrian safety within the WSU campus community. If successful, similar trials at an urban or city-wide scale can also be envisioned. In addition to improving pedestrian safety, this project will educate users and participants on the impact of technology on pedestrian safety and its role in improving the same. Project outcomes and results will be disseminated by means of peer-reviewed publications, white papers and open-source applications. Applications and anonymous data collected from the planned testbed will be appropriately disseminated to facilitate additional research and advances in the area of pedestrian safety technology.

This CAREER award from the Chemical Measurement & Imaging Program (with co-funding from the Instrument Development for Biological Research Program) supports the efforts of Professor Alexandre Shvartsburg at Wichita State University to develop new technologies for the characterization of biomaterials. Mass spectrometry (MS) is a technique used to identification and characterization biological and environmental samples. To enable application to complex samples, MS is usually preceded by a separation step, typically employing solution-based methods of liquid chromatography or electrophoresis. These methods are increasingly being replaced or complemented by much faster separations based on gas-phase ion mobility spectrometry (IMS), which can provide additional insight into elements of ion structure. Dr. Shvartsburg and his group are advancing the capabilities of IMS based on fundamentally new measurement concepts. The research is integrated with an educational program centered on an IMS exhibit in the Wichita Exploration Place and other science museums and discovery centers nationwide, and taken to schools as part of a K-12 outreach program. The exhibit emulates IMS separations demonstrating the key aspects of resolution and sensitivity in an interactive format. This effort is complemented by a summer program for faculty from undergraduate institutions and community colleges in Kansas, providing them with opportunities to learn more about MS, IMS, and their applications. Incorporation of this knowledge into courses taught at their home institutions may help prepare students to contribute to a technology-based economy.
Initial IMS methods were designed such that measured ion velocities are linearly proportional to the applied electric field. The relationship between field strength and velocity becomes more complex in strong fields, where ion mobility varies with field strength, enabling a newer technique called field asymmetric waveform IMS (FAIMS) that sorts ions by the difference between mobilities at high and low fields. FAIMS is capable of providing exceptionally fine separations, extending, in favorable cases, to separations of isotopic isomers (isotopomers). Dr. Shvartsburg is pursuing multiple approaches to advancing the resolving power of FAIMS by expanding the nonlinear IMS paradigm in fundamentally novel ways. One approach is higher-order differential IMS employing more complex asymmetric waveforms to achieve unique separations. Another is IMS with alignment of dipole direction, where the pendular locking of macromolecular dipoles permits capturing the directionally (rather than orientationally) averaged cross sections for more detailed structural characterization. Implementation of FAIMS at reduced temperatures may extend the pendular regime to smaller ions (including essentially all peptides) and avoid heating ions above room temperature, which can cause dissociation or structural distortion in high-field IMS systems. Assembly of multidimensional separations comprising linear and nonlinear IMS stages is central to this work. By devising and sharing teaching tools related to these sophisticated concepts, Dr. Shvartsburg is not only advancing our characterization capabilities, but also helping prepare students with the skills and understanding needed to advance the state of technology.

This award establishes a new Research Experiences for Undergraduates (REU) Site at Wichita State University. The REU Site will host undergraduate students from across the nation to conduct research during the summer with faculty mentors on networked cyber-physical systems. Cyber-physical systems are engineered systems that are built from and depend on the seamless integration of computational algorithms and physical components. Cyber-physical systems often present significant communications and networking challenges due to the complex, real-world environments in which the devices are expected to operate. The environments are diverse and range from operating underwater to flying in the air. They could involve use in manufacturing facilities or simple use as personal devices. The project plans to recruit a diverse cohort of undergraduate students each summer, including students from groups traditionally under-represented in computing. In addition to their research activities, the students will participate in other professional development activities that will prepare them for entering the computing workforce and for possible futures as researchers.
The REU site is led by faculty mentors from the computer networking group within the Department of Electrical Engineering and Computer Science at Wichita State University. The affiliated research laboratories provide students with opportunities to use state-of-the-art equipment and facilities to explore topics that are current and timely with faculty mentors who have significant experience and expertise in the area of networked cyber-physical systems. Realizing networked cyber-physical systems presents a rich set of research problems in areas such as indoor and outdoor positioning and localization, wireless communications and networking, security and privacy, cloud computing, mobile and wearable computing, and data analytics. The goals of the project are to advance the technical field of networked cyber-physical systems while simultaneously preparing the next generation of graduate students and workforce participants. This project is jointly funded by the Directorate for Computer and Information Science and Engineering (CISE) and the Experimental Program to Stimulate Competitive Research (EPSCoR).

Neutrinos are among the most abundant particles in the universe, emanating from stars, nuclear reactors, the core of the earth and even interactions from the early universe. Despite their abundance, there is limited knowledge about many of the fundamental properties of neutrinos such as their mass. A broad international research program is progressing to study the properties of these particles. One aspect of this program is to investigate neutrino oscillations: one type of neutrino changing into another type. Measuring these oscillations could lead to new models of particle interaction. In order for measurements to continue to improve, understanding how the neutrino interacts with other types of matter becomes critical. This project will carry out a focused research effort with the objective to characterize neutrino interactions with matter to enhance the domestic neutrino research program. This work will also have broad impact by enhancing the big data initiative at WSU, which is a multidisciplinary effort that seeks to engage the campus, its student base, and local industry in cutting-edge data analytic techniques which are applicable in a wide range of both industrial and academic fields.
This work will be accomplished by analyzing neutrino interaction data from the NuMI Off-axis electron-neutrino Appearance experiment (NOvA) near detector. The NOvA near detector is sited in the main injector neutrino source at Fermilab, just outside Chicago, Illinois. This setup provides a very intense, near mono-energetic source of neutrinos, and a detector ideal for measuring a broad range of interaction types. One of the limitations of neutrino oscillation measurement is the uncertainty in neutrino - nucleon interactions. This work will provide new and critical neutrino-nucleon measurements to help more fully understand the nature of neutrino interactions with matter while providing several young scientists opportunities to engage in world leading high energy particle physics research.
