David Goodman, PhD - US grants

This proposal is for a grant to establish a Industry/University Cooperative Research Center for Wireless Information Networks at Rutgers University. Wireless information services such as cordless telephone and cellular radio are technologically in their infancy. The aim of the research program at the Center is to overcome bottlenecks that restrict the growth and enhancement of wireless networking. The proposed systems research projects include; a) multiple access performance evaluation, b) object oriented systems integration in wireless networks, c) Dynamic spectrum reuse, d) optimization of the physical layer, and e) a wireless network testbed. The Program Manager recommends a continuing award of $50,000 each year for the next five years to Rutgers University for establishing a Center for Wireless Information Networks. Near the end of each 12 month period the Program Manager and/or the Director of the Engineering Centers Division will review the progress of the Center on a number of criteria, including the following: (1) the extent to which the university-industry interaction and collaboration is developing; (2) the extent to which the support base is expanding; (3) the extent to which a robust research program is developing. If the review is satisfactory, the Program Director will recommend support of the next period of this continuing grant.

Partial support is provided to defray travel expenses of participants in the 1992 Gordon Conference on Catalysis to be held June 29 to July 3 in New London, NH. Funds will be used for invited speakers and to assist young investigators who lack funding to attend the conference.

9416209 Goodman This is a "TIE" project on the topic of "Realizability of Potential of Multiuser Detection," to be conducted by the Industry/University Cooperative Research Center for Communications and Signal Processing at North Carolina State University and the Industry/University Cooperative Research Center for Wireless Information Networks at Rutgers University. The proposed activity is to conduct research to increase realizability and capacity of CDMA (Code-Division Multiple Access) systems. The proposed project will concentrate on the ability of multiuser detectors to combat multipath fading present in the actual mobile environment. This project is being cost shared with the Industry/University Cooperative Research Center for Communications and Signal Processing at North Carolina State University. The Program Director recommends the Rutgers University be awarded $50,000 for 24 months for this "TIE" project with North Carolina State University.

Abstract 9423707 The goal of this project is the synthesis, characterization, and surface chemistry of well defined, ultra-thin (less than 10 nm) oxide films. Ultra-thin oxide films will be prepared on refractory single crystal substrates and characterized using an array of surface science techniques, including low energy electron diffraction, Auger electron spectroscopy, X-ray and ultraviolet photoelectron spectroscopy and, ion scattering spectroscopy, reflection absorption Fourier transform infrared spectroscopy, high resolution electron energy loss spectroscopy, scanning tunneling microscopy/atomic force microscopy, and temperature programmed desorption. Ordered, oxide surfaces in thin film form will be prepared on single-crystal, refractor metal substrates. This approach will be extended to include a variety of oxide and mixed-oxide types. A methodology utilizing these highly ordered, stoichiometric oxide thin films offers a promising new strategy for studying the surface chemistry of these materials in ways precluded utilizing the bulk materials and traditional techniques. %%% This study impacts the basic science of oxides and various practical technologies such as environmental waste remediation, device fabrication, and catalysis. Because of the highly insulating nature of many oxide materials, their surface geometrical and electronic properties, in general, have received much less attention than, for example, metal surfaces. To date, extensive work on the chemisorption and catalytic properties of oxide materials have been conducted, however, the microscopic reaction mechanisms occurring on oxide surfaces are still not well understood. The principle reason for this is that these studies have been performed primarily on powder samples. Therefore, the information represents an average of the various crystal faces exposed in addition to a variety of defects which are inevitably present in the powdered samples. On the other hand, high-purity single cr ystals of many oxide materials have been difficult to obtain and studies of these insulating materials have often encountered the difficulties associated with surface charging, sample heating and cleaning. Therefore, there is a clear need for the synthesis of high quality, thin oxide films. Structural and chemisorptive properties of oxide materials can be obtained by preparing well-defined, thin oxide films whose properties are identical to their single-crystal bulk counterparts, thereby facilitating surface chemical studies of these materials under controlled conditions.

Abstract 9615033 Goodman This award provides funding for an NSF/Industry/University Cooperative Research Center on Wireless Information Networks (WINLAB) at Rutgers University and support of an undergraduate student to participate in the research of the Center. The research activities of the Center will contribute to the rapidly expanding technologies of wireless communications and mobile computing. The research proposed for the next five years of support is motivated by an analysis of personal communications in the year 2010. Projects that will be undertaken will build on research conducted in the first five years of WINLABOs operation and are in the categories of network architecture, mobile computing, radio resource management, access technologies, and mobility management. The Center will continue to collaborate with its thirty corporate and government sponsors and it is expected that this support will grow. Additional funding is provided in this award to support a minority undergraduate student for the summer to conduct a study on an ongoing research project within the Center.

The purchase of the multiprocessor SUN UltraSparc will greatly accelerate research in these areas, as well as in other projects involving DIMACS (an NSF S&T Center) and ECE and CS Departments at Rutgers, which currently do not have a comparable high performance multiprocessor with parallel thread support.

ABSTRACT EEC-9714727 GOODMAN This two year "TIE" project funds a collaborative study with two Industry/University Cooperative Research Centers (I/UCRC). The two I/UCRC's are the Rutgers University Industry/University Cooperative Research Center for Wireless Information Networks and the University of California San Diego Industry/University Cooperative Research Center for Ultra-High Speed Integrated Circuits and Systems. The "TIE" project is entitled, "Interference Cancellation Prototyping and ASIC Development for Wireless CDMA Communication." The Rutgers University I/UCRC will investigate the critical issues of acquisition and synchronizing essential for multi-user direct sequence CDMA communication convolution coding and utilize recent results on multi carrier DS/CDMA systems. In the second year further research to study other multi-user detection architecture will be carried out after adding radio frequency hardware. The University of California - San Diego Center will work with the Rutgers University Center in designing an interference cancellation chip and give it to National Semiconductor Corp. for fabrication . In the second year the chip will be tested and incorporated into a CDMA communication system for multi-users.

9814104 The Federal Communications Commission recently allocated three 100 MHz bands of radio spectrum for the Unlicensed National Information Infrastructure (U-NII), with only minimal controls on radio emissions. This unprecedented release of unlicensed spectrum provides fertile ground for technical research on coexisting systems in a wireless "ecology" and raises interesting policy issues which must be addressed if the U-NII is to become all it's envisioned to be. The WINLAB Focus '98 on the U-NII is to provide a forum for discussion of a broad U-NII research agenda for both technologists and policy makers. It is also intended to provide an introduction to those with an interest in this new and exciting field.***

This is a three-year continuing award. Collaboration is a hallmark of human activity. But today's society is becoming global, and digital networking-both wired and wireless-aims to serve geographically-dispersed participants. Networks of computers now become a mediating tool in human collaboration. And, their distributed architecture provides new opportunities for expanding human intellect and for enhancing knowledge work. But to be maximally useful the mediating system must be easy to use-preferably transparent to the user. Communication between human and machine should approach the naturalness of face-to-face exchange, where the sensory modalities of sight, sound and touch carry primary responsibilities for information transport. Additionally, supporting software must include intelligent agents able to fuse sensory data into meaningful commands for the machines. New technologies, now evolving, promise greater naturalness in human/machine communication-naturalness that substantially transcends the limitations of traditional mouse and keyboard. Incorporated with audio and video conferencing, these techniques include: eye tracking, visual gesture, hands-free speech recognition, speech synthesis, force-feedback tactile grasp, and manual gesture. Used in natural combination, these modalities provide the human greater dimensions of control and communication, and hence greater effectiveness in networked collaboration.

This new research, aims to establish the basic understanding necessary for the creation and use of multimodal computer interfaces in wired and wireless networks. The research aims to produce a design methodology for multi-user collaboration across heterogeneous architectures and computing environments. As multimodal capabilities evolve, human performance must be addressed as a recognized component of the total system. Optimization of design therefore includes human-factors assessment to quantify the synergies that can be won from multimodal interaction. The new research identifies three application sectors where wired/wireless multimodal collaboration can provide new solutions; they include: Telemedicine (where expert participants may contribute to diagnoses for remote patients); Crisis Management (where disaster relief and emergency aid may be planned and deployed collaboratively); and Mobile Offices (where business activities might be conducted in transit-air, sea or land). The design framework resulting from this research is also applicable to other activities important in today's society, including: ubiquitous and universal access to information systems; increased interaction with the World Wide Web; education and knowledge dissemination; and, new aids for disabled individuals.

The Second International Workshop on Oxide Surfaces (IWOX-2) is organized by Texas A&M University and will be held 15-19 January 2001. The goal of the workshop is to facilitate multidisciplinary interactions and information exchange within a multidisciplinary group of researchers and top post doctoral scholars and graduate students studying, fuel cells, and electronic devices. The NSF funds will be used to help invited speakers, graduate students, post doctoral scholars, and junior faculty participate in the symposium.

Important areas impacted by oxide surfaces include catalysis and electrocatalysis; photochemistry, photcatalysis and environmental remediation; biomaterials; ceramics; and sensors. Students trained in these multidisciplinary areas compete very well in the job market in areas such as energy, transportation, chemicals, and electronics, and often go on to contribute in many significant ways to the global economy.

The large number and diversity of quality of service (QoS) measures present a significant challenge to the design and operation of multimedia wireless communications systems. Each information source (data, audio, video) has its own metrics of signal quality and the network has an aggregate measure of capacity for each source (for example, Erlangs of telephone traffic and data throughput). In addition to signal quality and network capacity, the battery life of a portable terminal has a major effect on the value of mobile information services to consumers. Existing knowledge of quality optimization is generally confined to studies of individual sources. In the 1990s, a significant body of knowledge was created on radio resource management for cellular telephone communications. More recently, the research community has turned its attention to wireless data and video. Each study focuses on one or two quality measures for one type of information: for example, power and distortion for video; power and throughput for data.

This project takes a more comprehensive view by considering the collection of QoS measures to be a point in a multidimensional space. Given a system design and a set of operating conditions, the achievable points constitute a feasibility volume, with optimum points on the surface. Within this formulation, we study simultaneous transmission of data and video by analyzing projections of the volume onto various combinations of QoS dimensions including:
video distortion;
data throughput for each source;
data utility for each source;
total power dissipation (signal processing power and transmission power) in a terminal;
number of simultaneous video transmissions at a base station;
aggregate base station throughput;
aggregate base station utility.

The emphasis is on power efficient communications and the results provide guidance on joint adaptation of the following properties of terminals that transmit signals to the same base station: transmission power and rate in data terminals and transmission power, compression, and channel coding in video terminals.

Title: CISE RR: Instrumentation for Research on Energy Aware Multimedia Information Terminals

This project, performing studies related to minimizing the energy consumed by mobile cellular and wireless networking hardware, builds a framework to understand, model and measure power consumption, as well as dynamic allocation of resources to affect power consumption in portable multimedia communication devices. Three platforms constitute the focus for implementing signal processing algorithms (general microprocessors, e.g., Pentium and ARM), digital signal processors (DSP), and reconfigurable hardwarefine grain field programmable gate arrays (FPGA) and coarse grain Application Specific Programmable Processors (ASPP). The work considers two communications systems that will carry the majority of traffic in wireless Internets: cellular networks and wireless local area networks (WLAN). Because battery life depends not only on total energy drain but also on the voltages employed in the terminal and the temporal profile of energy consumption, the research includes experiments with lithium batteries to determine the effects on battery life of continuous discharge and pulsed discharge with various peak-to-average ratios. The results of these experiments are then merged with the results of signal processing and communications studies in an energy-management testbed that verifies predictions and demonstrates the effects of the new adaptation techniques. Hence, the following four components form the research plan:
Theoretical and simulation studies exploring power allocation among source coding, channel coding, encryption, and transmission in a multimedia, multiuser setting
Measurement and design study examining the power and energy requirements of signal processing algorithms and producing a software library of software modules, FPGA configurations, and ASPPs that can be dynamically selected by a portable device
Measurement and design study creating an intelligent power supply system that takes into account effects of battery discharge characteristics and demands of algorithms implemented on microprocessors, DSPs, FPGAs, and ASPPs.
Creation of experimental testbed running in the WLAN network from the results of the first three studies
The experimental testbed addresses three areas of research:
Power allocation among different components of the processing pipeline (source coding, channel coding, encryption, transmission);
Power and energy requirements of signal processing algorithms, producing a library of various granularity modules (software, FPGA, ASPP) to be selected dynamically; and
Power supply system that takes into account both battery characteristics and algorithms needs.
On the educational side, specific plans involve undergraduate students hands-on work, organization of workshop, and summer school. Industrial partners and international collaboration also form part of the research.

Goodman

This award supports a two-year collaborative research project between Professor David Goodman at Texas A&M University and Professor Yasuhiro Iwasawa of the University of Tokyo in Japan. The researchers will undertake a study of the physical and chemical properties of nanosized metal clusters on oxide surfaces. The collaborators will correlate those physical and chemical properties measured for Au and Rh clusters of varying size with their catalytic properties. They will stress the strengths of each group, namely, the synthesis capabilities of the Texas group and the unique characterization facilities of the Tokyo group, specifically for atomic force microscopy. These studies are essential to understanding the unique properties of nanosized metal clusters for catalytic applications, and a key to establishing a methodology for predicting new systems and new reactions to be addressed by this exciting class of materials.

This research will facilitate the collaboration between two strong surface chemical groups with complementary expertise and capabilities, allowing an important technical problem to be addressed with a broad array of modern surface methods. The project will offer a good opportunity to join efforts between the two countries. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. The project advances international human resources through the participation of graduate students. The researchers plan to publish results of the research in scientific journals and report on the findings at scientific meetings.

This proposal is to plan for a new multi-university I/UCRC that aims to promote a research program of interest to both industry and universities on technologies for wireless internet. This new multi-university center will be able to have a broad impact on the industry through having its existing resources enhanced by the addition of the partner that is also being recommended to receive a planning grant. The two partners are this University and Columbia University.

The proposed Center's goal is to work on two overlapping categories:

- Information delivery focussing on software development, addressing security and robustness, and
- Data transmission related to management of radio resources and the management of competition and cooperation between different technologies

The proposal deals with an area of significant need and by assembling the two institutions into one research team, the breadth and depth is enhanced

This collaborative Industry/University Cooperative Research Center will perform research in three critical, overlapping areas. Cooperative Communications and Networking research will examine wireless networks build out of nodes that cooperate at the physical and network layers. Cooperative networks offer enhanced capacity, reliability and efficiency relative to infrastructure and ad hoc networks. The second area of research focuses on extending the battery life of portable terminals thereby removing a major enhancing the convenience and value of wireless terminals and sensors. The third research area is Wireless Applications and associated Information Delivery mechanisms. Wireless Applications under investigation include content distribution, applications that leverage the ubiquity of wireless infrastructure with location awareness, and applications that adapt to the capacity limitations of the wireless vis-a'-vis the wired network. Each project focuses on a specific mode of wireless connectivity of the Internet to portable mobile information devices. In addition to developing and evaluating protocols and applications, Information Delivery research addresses security and robustness.

PROJECT SUMMARY/ABSTRACT This career development award will provide early career support for investigation of the management of infec- tious diseases in the setting of addiction in hospitals. The award will provide support for the candidate to develop expertise in the following areas: 1) addiction science research; 2) natural language processing; 3) machine learn- ing; 4) professional development; and 5) responsible conduct of research. For this, Dr. Goodman-Meza will be mentored by a multidisciplinary, cross-institutional team with expertise in addiction, infectious diseases, and data science. His primary mentor, Dr. Steve Shoptaw, has an extensive track record in addiction-related research and training of future independent investigators. His co-mentors include Dr. Alex Bui and Dr. Matthew B. Goetz. Dr. Bui is an expert in biomedical data science and heads NIH training programs in this field. Dr. Goetz has broad experience of productive infectious diseases clinical research within the Veterans Health Administration (VHA). The current opioid epidemic in the United States has been associated with an increase in infections, in particular hepatitis C and bacterial infections. Bacterial infections are the leading infectious diagnosis leading to hospitali- zation in individuals with an opioid use disorder (OUD), and incur significant healthcare expenditures. Despite the availability of opioid agonist therapy (OAT) in the form of methadone or buprenorphine, less than 20% of people with OUD actually receive OAT. Hospitalization for a bacterial infection may be an ideal time to initiate OAT, but the benefits of this practice are unknown. In this proposal, the candidate will assess the impact of initiating OAT in people who inject opioids admitted to the VHA due to a Staphylococcus aureus blood stream infection (bacteremia) ? the most common bacterial pathogen among people who inject opioids. Using data already collected for 36,868 cases of S. aureus bacteremia (SAB) from the VHA electronic data repository, the candidate will address three research questions: 1) is a natural language processing algorithm (NLP) more ac- curate than a standard International Classification of Diseases (ICD) code-based approach at screening records to correctly identify individuals who inject opioids in a cohort of patients admitted with SAB; 2) what are the temporal and geographic trends of SAB in people who inject opioids and those who receive OAT at the facility- level; and 3) using a machine learning framework, what are the estimated impacts of OAT on patient centered outcomes ? death, readmissions, leaving against medical advice, and subsequent outpatient engagement in OAT. These formative data will help the candidate to establish a productive early career as a physician-scientist and advise development of an OAT-delivery strategy to mitigate infectious complications of injection opioid use. Through this award, Dr. Goodman-Meza will establish himself as an expert physician-scientist at the intersection of infectious disease and addiction, poised to make significant contributions to this important area of medicine.
