Opening the Archives: Access to Information, Memory, and Justice Thirty Years After the End of the Brazilian Military Dictatorship
In 2012, Brazilian President Dilma Rousseff signed an Access to Information Law, establishing guidelines for declassifying documents and opening archives containing information about human rights violations committed by the Brazilian dictatorship (1964-85). She also appointed a Truth Commission to investigate the state’s involvement in torture and repression. Green has developed a joint project with a Brazilian historian to facilitate greater access to U.S. documents on Brazil for researchers in both countries. In conjunction with the Brazilian and U.S. National Archives, this collaborative team will coordinate a group of twelve Brown and two Brazilian students that will digitize and index U.S. State Department documents on Brazil from 1960 to 1980 that will appear on websites in Brazil and at Brown. The team will also identify documents for the Truth Commission’s investigations. This effort reinforces Brown’s reputation as the leading U.S. institution focusing on contemporary Brazilian history.

Solar Power by Optical Frequency Rectification with Plasmonic Concentrators Coupled to Junctions of Doped Mott Insulators
An alternative paradigm for the conversion of solar energy to electricity makes use of the collective electromagnetic nature of solar radiation instead of individual photons as conventional photovoltaic devices do. The electric field of sunlight is first intercepted by a nanoscale antenna, and then the oscillating electrical current is rectified into a useful DC current. Optical-frequency rectification – in effect a crystal radio that runs on visible light instead of radio waves – avoids altogether the mismatch between the photon energy and the semiconducting bandgap that limits the conversion efficiency of conventional photovoltaic cells. Solar rectification thus has the potential to create a cheaper and more efficient method for the exploitation of sunlight and could lead to a paradigm shift in solar technologies. This team will design and build prototype devices that combine plasmonic concentrators / antennas with novel rectifying junctions of doped Mott insulators to test the feasibility of the concept. A working device will be a compelling argument for external funding.

Three-dimensional Traction Mapping Distinguish Neutrophils from Healthy and Septic Donors
Neutrophils are the most abundant white blood cell in the circulation and are among the first cells to response to an injury or infection; they are essential for health. Patients with decreased numbers of circulating neutrophils, or with inherited defects in neutrophil functions, are susceptible to opportunistic infections and have impaired wound healing. Efforts to study neutrophils under physiologically relevant settings have found that these cells are highly sensitive to physical and biochemical cues that regulate the magnitude of the cellular response to an insult. In order to translate laboratory findings to a better understanding of how the cells function in vivo, this Seed team will study neutrophils in a three dimensional setting rather than on standard 2D surfaces. This synergistic effort between laboratories in the Departments of Surgery at Rhode Island Hospital and the School Engineering will investigate neutrophil tractions in native 3D collagen gels and quantify cellular differences between healthy and septic cells.
Phosphatase Inhibitor Design – A Unique Possibility for Brown University
The specific and reciprocal relationship between kinases and phosphatases controls most biological processes. Thus, when the balance is disrupted, the result is often disease. To date, efforts to modulate phosphate signaling to treat these diseases have focused on inhibiting kinases. However, it has recently become evident that the exquisite regulation of phosphorylation signaling is driven by tyrosine and serine/threonine phosphatases, rather than by kinases. Thus, one of the fastest growing areas of research is to identify potent, specific inhibitors of phosphatases. The Seed team will combine expertise in biochemistry, structural biology, biophysics and synthetic organic chemistry in order to develop novel, potent inhibitors of phosphatases. This project aims to develop novel peptomimetic inhibitors of the ser/thr phosphatase PP1 using data from multiple PP1 holoenzyme structures, molecularly characterize and optimize inhibitors that target the tyr phosphatase PTP1B, and develop new, potent immunosuppressant drugs using data from the ser/thr phosphatase calcineurin and chemical scaffolds already shown to target calcineurin.

Making Sense of the Data Windfall: New Statistical Approaches to Evolutionary Analyses of Gene Expression
Many studies analyze gene expression to identify genes that play a functional role in particular biological processes. New tools make it possible to inexpensively measure the expression of all genes in a tissue sample. These tools, as applied in current study designs, are proving to be blunt instruments that turn up thousands of candidate genes for a particular biological process, most of which are erroneous by-catch. There is critical need to sharpen the focus of gene expression studies so that they identify a smaller set of more relevant genes. We propose to address this by adding an evolutionary dimension to gene expression studies. It will then be possible to identify speciﬁc genes that have evolutionary shifts in expression that are correlated with evolutionary changes in biological processes of interest. The hurdle to this approach is that statistical methods have not yet been developed, implemented, and tested for evolutionary analyses of high-throughput gene expression data. This project assembles an interdisciplinary team to do exactly this, and leverages Brown’s strong investments in genome sequencing and high performance computing.

The Role of Electrical Coupling Between Mitral Cells in Olfactory Coding*
Smell is the primary sense used by many animals to find food and mates and to avoid predators. Olfactory deficits in people are associated with loss of appetite, anhedonia and depression, and olfactory dysfunction can be an early sign of neurodegenerative diseases. The basic mechanisms by which the brain discriminates odors are obscure. Odors are detected by sensory neurons in the nose that project to special neurons called mitral cells. Patterns of mitral cell activity are transformed by the brain into the percept of a smell. Some mitral cells are electrically coupled through structures called gap junctions, also known as electrical synapses. This Seed team combines multidisciplinary expertise and the techniques of mouse genetics, electrophysiology, and behavioral analyses to study the role of electrical synapses in olfactory coding.
The Role of the Right Hemisphere in Speech and Lexical Processing*
Past research using a variety of populations and research methodologies has produced conflicting findings on the role of the right hemisphere in speech and lexical (word) processing. This project research aims to examine this question by analyzing the effects of right hemisphere lesions on speech and lexical processing in the context of current models of the functional architecture of language using state-of-the-art behavioral paradigms, measures, and neuroimaging techniques. This novel approach will add to the continued and growing strength of the Brain Sciences at Brown by contributing to the breadth of approaches used and potentially opening new directions of research examining language functions of the right hemisphere using functional neuroimaging and the application of basic research findings (bench) to language rehabilitation (bedside). Additionally, it will add a new recruiting site at the Rhode Island Hospital.

Development of New Computational and Point of Care Platforms for HIV Drug Resistance**
HIV drug resistance is a major cause of treatment failure. The ability to identify drug resistance is important in patient care, and identification of specific drug resistance mutations can assist in efficient regimen design. Resistance testing, required in developed countries, is rarely used in resource-limited settings due to financial and infrastructure constraints. This is a major hurdle in the fight against HIV/AIDS since the vast majority of this pandemic is in resource limited settings. This project builds on preliminary research and a newly-developed microfluidic method termed SMART (Simple Method for Amplifying RNA Targets), to be integrated into a point of care chip platform, for drug resistance detection in resource limited settings. This Seed team will develop a computational platform for global analysis of position-specific pol sequence variation across geographic regions within HIV1 subtypes, develop a SMART Microfluidic Platform to amplify and detect drug resistance in a full-length HIV1 plasmid, and validate the platform in HIV-infected patient samples.

Climate Change, Biological Evolution, and Biogeochemical Cycles in Lakes of Central Sulawesi, Indonesia
The overarching goal of our research is to investigate coupled climatic, environmental, and biological evolution in central Indonesia over the last ~700,000 years. Indonesia lies at the heart of the Indo-Pacific Warm Pool, the largest pool of warm ocean water on Earth. Evaporation and rainfall over Indonesia controls the amount of water vapor in the Earth’s atmosphere and globally important climate processes such as the El Niño-Southern Oscillation. Long-term variations in Indonesian rainfall, combined with the tectonic evolution of the Indonesian archipelago, provide the environmental backdrop for the evolution of some of the most diverse ecosystems on Earth in Indonesia’s rainforests and lakes. We will investigate this variability by developing a Brown-led interdisciplinary science team to drill and analyze sediments from Lake Towuti, central Sulawesi, the largest lake in Indonesia.

Traffic Pollution and Acute Cardiovascular Events in Post-Menopausal Women
Cardiovascular disease is the leading cause of morbidity and mortality in the U.S. Wellenius will lead the first detailed study in a nationwide context of whether traffic pollution may increase the risk of cardiovascular events. This project will evaluate the association between long-term exposure to traffic pollution and cardiovascular risk within the Women’s Health Initiative (WHI), a large, national, prospective cohort study of 161,808 postmenopausal women. The proposed work is part of a broader research program to understand how different sources of ambient air pollution influence cardiovascular disease risk. The findings will likely have direct relevance on cardiovascular disease prevention by informing public health policy regarding the need for refinements to air pollution regulation, and position Brown University at the center of an exciting, important, and highly visible area of public health research.

Molecular and Cellular Mechanisms Underlying the Transition from Acute to Chronic Pain
Chronic pain is a serious health problem affecting millions of people in the USA alone. Chronic pain is highly prevalent in patients with diabetes, cancer, autoimmune deficiency, and following peripheral nerve injury. Strong evidence supports the theory that chronic pain is a maladaptive response of neurons to tissue injury or inflammation. The synapse is the site where neural transmission is scaled up and down in response to changes in neuronal input, but it is also now recognized as the critical pathological site in several brain diseases. Lipscombe and Kauer propose to begin to define fundamental cellular and molecular steps that support the development and maintenance of long-term changes in synaptic efficacy in the spinal dorsal horn, and then examine synaptic plasticity in the dorsal horn in animal models of chronic pain. The seed grant will allow them to garner preliminary data for future NIH applications.

How Do Funding Mechanisms Affect Health Care Choices? Action for Health and Children’s Health in Mali
A key barrier to the cost-effective delivery of health care services in low-income countries is the lack of a full understanding of how families make decisions about when and where to seek healthcare. The aim of this project is to study these decisions in the context of children’s care. Sautmann and Dean will assess the relative importance of different factors that may affect the parents’ choice: financial constraints and costs; information and beliefs about the child’s need for care; and the preference of parents about trade-offs they must make e.g. between spending today and tomorrow, certain or uncertain outcomes or healthcare for their children versus other expenses. They frame their analysis in a dynamic model of healthcare decision-making, and use a randomized control trial of the “Action for Health” program of the Mali Health Organizing Project to estimate this model. The results will allow the researchers to predict changes in parents’ behavior and their impact on children’s health outcomes in response to different healthcare funding mechanisms.

The Impact of Agricultural Practices on Greenhouse Gas Emissions and Air Quality: A Case Study in New England
On a global basis, microbial activity in soils accounts for as much as 35% of nitrous oxide (N2O) emissions and nearly 20% of nitric oxide (NO) emissions. These trace gases are important in regulating Earth’s climate, while also influencing local air quality and acid rain deposition. Changes in N2O and NO emissions are anticipated with global changes in temperature, precipitation, and nitrogen fertilizer use, providing great potential for important feedbacks onto the climate and atmospheric systems. Hastings and Tang will develop a new system for automatically and simultaneously measuring the flux of N2O and NO from agricultural soils, and utilize this new technology in a pilot study to quantify the response functions of N2O and NO to parameters such as temperature, soil moisture, and nitrogen availability.

Governance and Inequality in Indian Cities: A Seed Grant Proposal
Indian cities face tremendous challenges of governance because of entrenched inequalities and accelerating urban migration. Yet the social science literature on urban governance in India is conspicuous by its absence. This interdisciplinary team proposes to fill this gap through a long-term research project that is motivated by three fundamental questions. First, what are the predominant patterns of inequality in urban India and how is inequality structured? Second, how are Indian cities governed and how do these patterns of governance both reflect and impact patterns of inequality? Third, what forms of identity emerge in the migrant communities, as they come from villages to cities? And how do they view the state and fellow citizens? Who is us, who is them? This question, not often asked, is important for governance, for forms of consciousness have a relationship with what kinds of politics and political structures emerge, how political parties or civil society organizations mobilize citizens.
Novel Micropatterned Culture Model for Developing New Therapeutic Strategies for Sudden Cardiac Death
Sudden cardiac death is a leading cause of death in industrialized countries. It is most commonly caused by ventricular fibrillation, a fatal heart rhythm disturbance (arrhythmia). Emerging evidence indicates an important genetic contribution to sudden cardiac death; however, the molecular determinants have remained elusive. This project aims to develop a highly innovative and translational culture model of human cardiac arrhythmia by patterning cardiomyocytes derived from neonatal transgenic rabbits carrying a human mutation causing long QT type 2 syndrome, a common genetic cause for sudden cardiac death. Hoffman-Kim, Mende, Koren and Choi will use this new culture model to investigate arrhythmia formation, the mechanisms underlying the protective effects of progesterone as well as identify progestin molecules ideally suitable to prevent cardiac arrhythmias and sudden cardiac death in long QT syndrome.

Genetic, Biochemical, and Bioinformatic Approaches to Understanding Microbial Degradation of Plant Biomass
The development of renewable energy sources, which can supplant fossil fuels, is of utmost importance. As replacements for fossil fuels, biofuels are helping to meet the growing global demands for energy. The proposed research project will establish a conceptual framework for genetically engineering microorganisms to produce biofuels from plant biomass, a renewable and readily available source of carbon. Inspiration for this strategy comes from the abilities soil-dwelling microorganisms to degrade and consume plant biomass. We have assembled a research team with complementary and appropriate expertise to mine and elucidate the metabolic pathways for plant biomass consumption in soil-dwelling Streptomyces bacteria. By necessity, the project involves the synergistic application of experimental methods from genetics, biochemistry, computational biology, and chemistry.

Focusing on the role of galactose in cell wall synthesis and degradation, the project will use a combination of focused forward chemical-genetic and targeted reverse genetics methods, along with protein localization studies, to explore galactose metabolism in the context of rapid pollen tube extension. This team is dedicated to unraveling the complexities of cell wall synthesis and breakdown, work that impacts the biofuels and energy arena. The development of energy from renewable resources is one of the greatest challenges facing scientists today, and this work will help Brown establish a strong presence in this area.
Tracking Disease Spread Through the Wildlife Trade: New Techniques to Identify Infectious Microbes in Aquarium Fishes
Since 2000, the US has imported more than 1.4 billion live animals, representing thousands of species from more than 194 countries. More than 90% of these animals were aquarium fishes intended for pet shop sales. Contact with aquarium fishes is increasingly linked to human infections by bacterial species including Salmonella, Streptococcus, Mycobacterium and Aeromonas. Using intensive sampling methods and experimental manipulations, Smith and Amaral-Zettler will track changes in pathogen species richness and infection rate in select aquarium fishes as animals arrive in U.S. pet shops and are sorted into store tanks. The findings will advance the conceptual bases of disease ecology and invasion biology and inform future efforts to regulate wildlife trade to reduce disease introductions.

Discovering RNA Regulatory Elements in Drosophila
Conserved DNA elements that regulate gene transcription are increasingly well understood, thanks to recent advances in genome location (ChIP-chip and ChIP-seq). However, cis-regulatory elements in RNA are less well resolved, and comparable technologies have yet to be developed. With the complete genomes of twelve species of Drosophila, opportunities present themselves to leverage the data-set into testable models for new RNA control elements. Previous studies have demonstrated that splicing enhancer motifs have signature distributions relative to splice signals. The project will apply this observation to discover sequences which are important for a variety of RNA processing or regulatory events. In addition, the project will perform powerful biochemical, genetic and targeted knockout experiments to test its hypotheses.

Molecular Analysis of a Bistable Switch in the Pathogen Candida albicans
Candida albicans is the most commonly isolated fungal pathogen and is responsible for debilitating mucosal infections as well as life-threatening systemic infections. Despite its prominence as a human pathogen, relatively little is known about virulence factors in C. albicans compared to bacterial pathogens. One feature of Candida biology that has been linked with pathogenicity is phenotypic switching, in which strains convert rapidly and reversibly between alternative phenotypic forms. This proposal will examine one such phenotypic transition, the white-opaque switch, which influences both the virulence of C. albicans strains and their ability to form biofilms.

Transcript Turnover in the Egg-to-Embryo Transition: Basic and Clinical Applications
The growing number of patients seeking assisted reproductive procedures underscores a critical need for a sensitive method to predict an embryo's successful development. Currently, clinicians rely strictly on a visual assessment to decide which and how many embryos to implant. However, the high risks and ethical, emotional, and developmental issues demand more of the clinician. Improved technology and a better understanding of the embryo can enable a more stringent evaluation for embryo prioritization.

Development of a "Spouted Bed" Direct Carbon Fuel Cell (SB/DCFC)
In 2005, one billion tons of coal were consumed in the US for electricity generation. Given the increasing demands for electricity and the constraints on natural gas and nuclear power, coal will continue to play a very important role in the energy future of this country. In conjunction with Oak Ridge National Laboratory, this research is focused on the construction and characterization of a prototype of a new kind of direct carbon fuel cell (DCFC) that is being developed to circumvent some of the more important shortcomings of current DCFC designs. DCFCSs are electrochemical devices that produce electricity directly from carbonaceous sources, such as coal and biomass, without combustion or gasification. With much higher theoretical efficiencies than thermal power plants, DCFCs can significantly reduce CO2 emissions, as well as many other pollutants generated by conventional coal-fired power plants.
