Precursors of Hypertension: the Meharry Cohort Study @ Meharry Medical College
This is a prospective longitudinal study of black former medical students to identify possible precursors of hypertension. Socioeconomic, biomedical and psychological assessments were obtained 20 to 25 years previously during the period they were enrolled at Meharry Medical College, 1958-1965. The participants were re-examined while practicing physicians during the period from 1981-1984. Follow-up data were obtained on approximately 80 percent of the original cohort, and consisted of updated medical history, family history, weight, height, blood pressure, pulse, electrocardiogram, Jenkins Activity Survey, and smoking habits. These data will be analysed to determine the value, if any, of the variables obtained at initial examination in predicting future hypertension. If such a model is obtained then possible intervention that might alter or prevent hypertension in a similar group may be determined. In collaboration with investigators of Johns Hopkins School of Medicine, data from this study will be compared with those of a similarly studied white cohort over the same time period. The activities to be conducted under this revised proposal are 1) Completion of data analysis, 2) Preparation of manuscripts; and 3) Further attempts to contact and/or account for the 20% of the cohort presently missing.

Signal Processing For Acoustic Emission and Ultrasonic Testing
This project proposes to apply recent advances in the development of processing algorithms and programmable integrated circuits to nondestructive evaluation (NDE). Two NDE research areas are addressed, data acquisition and flaw detection. In data acquisition, it is proposed to investigate the use of adaptive waveform coding to reduce the sampling rate and the digitization word size and the use of signal decimation to reduce sampling rate. The significance of these two areas of research is that a lower sampling rate, provided signal fidelity is preserved, implies easier processing, and a reduced work size requires smaller data storage. In flaw detection, it is proposed to carry out research in improving the resolution in pulse echo flaw detection by signal correlation.

U.S.-Japan Cooperative Research: Phase Transitions in Dense Astrophysical Plasmas @ University of Rochester
This award provides support for a two year cooperative research project on dense astrophysical plasmas, between Professor Hugh M Van Horn, Department of Physics and Astronomy, University of Rochester, and Professor Setsuo Ichimaru, Department of Physics, University of Tokyo, Japan. In dense astrophysical objects, such as neutron stars, white dwarfs, low mass stars (brown dwarfs), the solar interior, and giant planets, collections of ionized nuclei and electrons constitute dense plasmas, which exhibit various kinds of phase changes. In recent years, due to advancements in condensed-matter theories coupled with progress in computer-simulation capabilities, it has become possible to carry out detailed analyses of those phase-transition processes in dense astrophysical plasmas. The aim of this proposal is to undertake theoretical and computer-simulation studies on a number of those phase transition processes. The processes to be studied include: (1) the possibility that neutron stars may have glassy rather than crystalline crusts, and what the consequences are of that; (2) the possibilities of phase separation in binary carbon/oxygen and iron/carbon mixtures, which have been suggested as energy sources in very cool white dwarfs; (3) iron/hydrogen phase separation, which may have interesting consequences for the evolution of low mass stars and "brown dwarfs"; and (4) hydrogen/helium phase separation in giant planets and brown dwarfs, which may prove a significant energy source in these bodies. The two groups involved in this collaboration complement each other well. The Japanese scientists have a long history of important contributions in areas of dense plasma physics and condensed matter physics relevant to this collaboration, and also have a strong interest in astrophysical applications. The US group has a similar interest in astrophysics, together with a strong interest in the relevant properties of matter at high densities. If successful this project will make a significant contribution to research problems at the interface between the disciplines of dense plasma physics, condensed matter physics and astrophysics.

Studies of Degenerate Stars @ University of Rochester
Among the most impressive strides in astrophysics over the last decade has been in the area of the physics of compact stars. Part of the reason for these advances has been the less visible but equally important progress made in the theory of their internal structure. In the past several years the Principal Investigator (PI) has been at the forefront of the application of solid-state theoretical physics to the construction of models of white dwarfs and neutron stars. This three-year award will provide support for the continued research in this general area, including a wide variety of topics ranging from neutron stars, to "brown dwarfs," to giant planets. This work will include research into the oscillation frequency spectrum (how these objects vibrate) as well as the "equation of state" in them which permits an estimate of temperature and pressure in their interiors.

P01Activity Code Description: For the support of a broadly based, multidisciplinary, often long-term research program which has a specific major objective or a basic theme. A program project generally involves the organized efforts of relatively large groups, members of which are conducting research projects designed to elucidate the various aspects or components of this objective. Each research project is usually under the leadership of an established investigator. The grant can provide support for certain basic resources used by these groups in the program, including clinical components, the sharing of which facilitates the total research effort. A program project is directed toward a range of problems having a central research focus, in contrast to the usually narrower thrust of the traditional research project. Each project supported through this mechanism should contribute or be directly related to the common theme of the total research effort. These scientifically meritorious projects should demonstrate an essential element of unity and interdependence, i.e., a system of research activities and projects directed toward a well-defined research program goal. |
Genetics of Neuronal Recognition in Drosophila @ Salk Institute For Biological Studies
A normal functioning nervous system depends upon the ability of neurons to recognize and synapse with their appropriate target cells during development. Although the cellular events involved in this type of cell interaction have been well described in both vertebrates and invertebrates, the underlying molecular mechanisms are poorly understood. Our long-term goal in this project is to understand the molecular basis of these neuronal recognition events. The approach we have taken is to use the genetics of Drosophila to identify genes and gene products that are involved in neuronal recognition. To this end, we have isolated mutations that alter the synaptic connections between identified neurons within a simple neuronal circuit. One of these mutations, called bendless (ben), appears to alter the recognition event leading to proper connectivity between two well characterized neurons of the circuit, the giant fiber and one of its post-synaptic targets, the TTM motoneuron. We have mapped the genomic location of the ben gene on a molecular walk through the region, and propose both to identify the ben transcription unit and to use molecular genetic and transformation techniques to study the role of the ben gene product in the target recognition process. We will determine which cells require ben function, and also misexpress the gene during development. We expect that these experiments will provide us with a better understanding of the target recognition process and its molecular basis, not only in Drosophila, but in higher vertebrates as well.

The Polar T3 Syndrome: Metabolic and Cognitive Manifestations, Their Hormonal Regulation and Impact Upon Performance @ Henry M Jackson Fdn For Advmt of Military Medicine
9418466 Reed People who live and work in Antarctica for longer than four to five months develop a characteristic constellation of symptoms and hormonal changes called the Polar T3 Syndrome. These people have previously been described as having a 40 percent increase in energy requirement, frequent mood disorders, doubling of the production, utilization, and tissue stores of the most active thyroid hormone, triiodothyronine (T3), a decline in central nervous system thyroxine (T4), and acquisition of physiologic cold adaptation. These apparent discordant and compartmentalized tissue responses will be studied over a four-year period utilizing a multidisciplinary approach carried out by experienced polar physiologists, endocrinologists and psychologists. The possible cognitive and metabolic changes in performance from declines in central nervous system T4 and elevations in skeletal muscle T3 content will be studed. Placebo-controlled T4 replacement directed at the central nervous system deficit will be carried out and measured with cognitive instruments. T3 content within the cardiovascular system will be evaluated by utilizing submaximal exercise testing to differentiate resting from activity mediated energy use contributions by the skeletal muscles. Additionally, tissue samples of skeletal muscle will provide information regarding the genetic coding for T3 responsive proteins to help better characterize the thyroid status of these muscles. Moderate energy restriction will be used along with T4 supplementation to study the dependence of T3 production, distribution and tissue stores upon both pituitary generation of thyrotropin and energy intake. Analysis will be carried out using each subject's baseline determined in the predeployment situation of California and compared with periods and standardized measures obtained during the antarctic summer and winter. It is proposed that a correction of the low T4 state in the central nervous system can be managed w ith T4 supplementation without dramatically changing energy requirements as suggested by previous human studies using cold air chamber experiments. If this thesis is correct, then characteristic declines in mood and memory during winter seasons in circumpolar regions may be attenuated by T4 supplementation without disadvantageous effects upon their energy metabolism. Additionally, this project will expand information regarding the ultimate regulation and maintenance of the increased T3 production which is a central determinant of the Polar T3 Syndrome.

Intergration of High Performance Liquid Chromatography Into the Chemistry Curriculum and Environmental Undergraduate Research Experiences @ University of Michigan Ann Arbor
Chemistry (12) This project focuses on enhancement of our undergraduate chemistry and environmental science programs by introducing high performance liquid chromatography (HPLC) in the laboratory courses of instrumental analysis and environmental chemistry as well as in multidisciplinary environmental projects. Laboratory experiments are being adapted from the research and educational literature and implemented into the undergraduate curricula as well as the research projects that are tied to local environmental issues. These laboratory experiments allow our students to perform qualitative and quantitative analysis of environmental and biological samples, and to develop problem-solving skills by conducting open-ended research projects. The integration of the lab experiments with the research projects increases students' competence in chemical analysis, and thus motivates them to further explore/solve "real world" chemistry and environmental problems. We plan to disseminate the outcome of this project by hosting a professional workshop that targets the chemistry faculty at local community colleges and science teachers at local high schools.

Mri: Acquisition of An Atomic Force Microscope to Enhance Research and Teaching in the Physical and Biological Sciences At the University of Michigan-Dearborn @ University of Michigan Ann Arbor
Technical Abstract
The Department of Natural Sciences at the University of Michigan-Dearborn (UM-D), a non-Ph.D. granting institution, will acquire a new AFM to build a comprehensive research and teaching program at the interface of physical and biological sciences. The present instrument offers full range of scanning probe (SPM) techniques ideal for research areas ranging from material science to polymer characterization. The liquid imaging package included in the instrument expands its applicability to biological research and the optional MFM mode of imaging will facilitate its application in the research involving magnetic materials. This instrument will be used to support several interdisciplinary research programs including (1) in situ synthesis of metal nanoparticles on monolayer templates, (2) vertically aligned carbon nanotube arrays on metal and semiconductor surfaces to develop a new sensitive and rapid DNA-detection method, (3) nanostructures generated from self-assembly of diblock copolymers to create DNA/protein nanoarrays, (4) single molecule-based activity of metal binding protein like Metallothioneins (MTs) or metallothionein-like (MT-L) proteins in yeast, (5) research on spintronics and (6) dilute magnetic semiconductor materials. Development of such a program will lead to unique opportunities for undergraduates to participate in multidisciplinary research areas of nanotechnology and nanobiotechnology and also promote the participation of under-represented minorities in biological and physical sciences. As an outreach program, the proposed instrument will provide an opportunity to develop new science activities/workshops to introduce the interdisciplinary aspect of biology and nanotechnology to high-school students in the Detroit metropolitan area, and will also create opportunities for them to actively participate in summer research.
Lay Abstract
Nanotechnology is the use of novel and unusual properties, phenomena, and processes that occur when size is reduced to 0.1 to 100 nanometer (one nanometer is one billionth of a meter), and the advent of nanotechnology brings together physics, chemistry, material and biological sciences. It has already brought and further promises to bring new devices that will revolutionize many areas of our technology. Nanobiotechnology is an emerging area of science which connects nanotechnology to biological systems. An Atomic Force Microscope (AFM), which is considered as the "eye of nanotechnology", is an integral part of this interdisciplinary area of science owing to its unique capability of direct observation and understanding of nanometer scale molecular structures present in chemical and biological systems. The AFM in the Department of Natural Sciences at the University of Michigan-Dearborn (UM-D) will attract prospective students intending to work in the interdisciplinary research areas involving physical and biological sciences like nanotechnology/nanobiotechnology. In addition, this instrument will have a major impact on our plan to develop a number of courses involving nanotechnology and will further expand the opportunity of undergraduate student participation in faculty research programs. The AFM will also be of great support to the current outreach program of the department with local community colleges and to improve the K-12 science education of Detroit metropolitan area.

Quantum Transport in Strongly Interacting Fermi Gases @ North Carolina State University
This program experimentally studies an optically-trapped, strongly interacting Fermi gas of Li(6) atoms as a model of universal quantum transport. This system offers unprecedented opportunities to test theoretical techniques that cross interdisciplinary boundaries, from condensed matter to nuclear matter. Measurements in ultracold Fermi gases now unite the coldest matter in the universe to the hottest matter, a quark-gluon plasma produced in gold ion collisions, which is comparable to the state of matter that existed microseconds after the Big Bang. Remarkably, both systems are found to be nearly 'perfect' fluids, in the context of a recent conjecture derived using string theory methods, with a similar ratio of viscosity to entropy density, despite a difference in temperature of 19 orders of magnitude and a difference in density of 25 orders of magnitude.
The proposed tabletop experiments impact theories of strong interactions in intellectual disciplines well outside atomic physics, including materials science and condensed matter physics (superconductivity), nuclear physics (nuclear matter, quark-gluon plasma), high-energy physics (effective theories of strong interactions), and astrophysics (compact stellar objects). The proposed research may have practical impact in helping to determine whether it is possible to create super-high temperature nearly perfect conductors based on normal fluids, which would operate far above room temperature--materials that would enable energy-saving power lines and magnetically levitated trains. For this reason, the proposed program fits very well into national initiatives on energy and materials science.

Quantum Hydrodynamics in Interacting Fermi Gases @ North Carolina State University
This project explores the nearly perfect fluid-flow properties of a special class of ultra-cold atoms, Fermi gases, which are tightly confined in a bowl made of laser light and cooled to temperatures just billionths of a degree above absolute zero. The bowl is turned off to release the ultra-cold atoms into a high vacuum and they are imaged during expansion by laser flash-photography. By just turning a knob in these tabletop experiments, an expanding atom cloud can be made to simulate the behavior of electrons in superconductors, neutrons in neutron stars, or even an exotic state of matter that existed just microseconds after the Big Bang. The study of these nearly perfect fluids has practical significance in testing theories of high temperature superconductors, which will one day enable energy-saving power transmission, and fundamental significance in testing theories of perfect fluid flow that may have occurred just after the Big Bang.
The goal of this project is to measure precisely the nearly perfect hydrodynamic transport properties of an ultra-cold atomic Fermi gas. Spin-up and spin-down atoms are made to strongly interact by means of a bias magnetic field, tuned near a collisional (Feshbach) resonance. A collision between two such clouds produces shock waves as the strongly-interacting clouds bounce off each other. Measurements of the shear viscosity above, at, and below resonance will enable new tests of the lower bound predicted for a perfect fluid using string theory methods. Studies of scale-invariant flow at resonance will determine the bulk viscosity and test general predictions for scale invariant systems. The experiments cross interdisciplinary boundaries by testing state-of-the-art theory for the transport properties of strongly-correlated matter, which can be simulated in these cold atom experiments, such as high-temperature superconductors, nuclear matter, and quark-gluon plasmas that are created in heavy ion collisions.

Quantum Hydrodynamics and Energy Flow in Fermi Gases @ North Carolina State University
This project uses laser flash photography to image the nearly frictionless fluid flow and energy flow of a unique ultra-cold atomic gas confined between sheets made of laser light. This special atomic gas has the properties of being "strongly interacting," and "fermionic" which causes it to behave in many ways like a liquid metal. When two clouds of these atoms collide, they bounce off of one another, creating shock waves. These experiments simulate properties of exotic matter in intellectual disciplines well outside atomic physics, including neutron stars and quark-gluon plasmas, which existed microseconds after the Big Bang. The experiments also test theories of super-high temperature superconductors, which operate far above room temperature, enabling energy-saving power lines and magnetically levitated trains. The project provides an ideal learning opportunity and serves to train undergraduate students, graduate students, and post-doctoral associates, who work as a team in a supportive environment with the PI to devise, construct, and perform new experiments, and to theoretically analyze the results. With this broad training, graduating students and post-doctoral associates are well situated to be leaders in tackling research questions that arise in science and engineering.
This project will study hydrodynamic transport and energy flow in a Fermi gas of 6Li atoms trapped in designer optical potentials. The potentials will imaged onto the cloud from a digital micro-mirror device (DMD) to control the spatial profiles of the atomic gas density and temperature. Confining the atoms between two repulsive sheet potentials enables in-situ imaging with nearly constant atom density along the line-of-sight direction perpendicular to the sheets. This suppresses unwanted averaging of the measured column density over hydrodynamic and low density ballistic regions, which has plagued previous studies. With tunable interaction strength, this method offers new opportunities to explore concepts that cross interdisciplinary boundaries, including local transport properties of scale-invariant systems, recent conformal field theory predictions of quasi-steady state energy flow between scale-invariant systems at different temperatures, and shock wave formation in strongly interacting fluids. The goals of this project include in-situ measurements of i) 1D hydrodynamic flow, local shear viscosity and thermal conductivity; ii) Energy flow between two scale-invariant clouds at different temperatures; iii) Shock wave formation versus interaction strength, temperature, and density profiles.

Fluid Dynamics in Uniform Fermi Gases @ North Carolina State University
General audience abstract
This project will explore nearly perfect fluid flow in a ?designer? quantum system, comprising a unique ultracold gas of atoms, contained in a box made entirely of laser light. The atoms used in these tabletop experiments feature experimentally adjustable attraction or repulsion, from very weak to very strong, enabling measurements that impact theories in intellectual disciplines well outside of atomic physics. The contained atoms model new materials, such as super-high temperature superconductors that operate far above room temperature, which will one day enable energy-saving power lines and magnetically levitated trains. Students and post-doctoral associates will design new optical systems, new computer control and mechanical systems, and study electrodynamics and quantum mechanics, broadly training them for challenges arising in science and technology.
Technical audience abstract
The experiments will study the fluid dynamics of a Fermi gas of Li-6 atoms near a collisional (Feshbach) resonance, which enables magnetic control of atom-atom interactions. The ultracold Fermi gas is contained, perturbed, and imaged in a designer optical potential, which is generated using two digital micro-mirror arrays. By imaging the atom density profile as a function of time, the new experiments will measure the hydrodynamic linear response and transport properties as a function of temperature, interaction strength, and spin-imbalance. Imaging the trapped cloud in a 1D linearly varying potential will determine the equation of state. Designer optical potentials also will be used for in-situ imaging of shock waves as a function of interaction strength, density profile and temperature profile.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
