The aurora is an important space weather phenomenon that links what is happening much farther away from the Earth in space to our atmosphere. During magnetically disturbed conditions, electrons that precipitate or rain down into the sky cause these brilliant lights. The precipitating electrons are a source of energy to the atmosphere and can cause space weather effects that are of concern to society and national space security. For example, the redistribution of energy from the precipitating electrons can affect predictions of orbits of satellites in the atmosphere and/or predictions of the location of re-entry of spacecraft back to Earth. The proposed research activities will lead to improved scientific understanding and modeling of the very complex auroral electron precipitation effects. The research outcomes will contribute to a broader NSF-supported community effort of Geospace Environment Modeling (GEM) for advancing space weather models. It enables two underrepresented female scientists to engage in fundamental research that will positively impact national space security concerns. The project will involve career mentoring of an early career female scientist and research training of diverse undergraduate student interns at The Aerospace Corporation that are vital for supporting diversity, equity, and inclusion in the next generation of space scientists and engineers. The objective of this proposal is to understand better the role of diffuse and discrete auroral electron precipitation on magnetosphere-ionosphere (MI) electrodynamic coupling. The science questions are (SQ1) How does diffuse auroral electron precipitation affect the auroral ionospheric conductivity, height-integrated conductance, field-aligned currents, and the ionospheric and inner magnetospheric electric field through the electrodynamic MI coupling during magnetic storms? Can a magnetically and electrically self-consistent treatment of the particle transport and loss, including diffuse auroral precipitation, account for observed conductance (PFISR), field-aligned currents (AMPERE), and electric fields (PFISR, DMSP, Van Allen Probes) during storms? (SQ2) What are the ionospheric conductivity and height-integrated conductance associated with representative discrete auroral electron precipitation in localized regions during magnetic disturbances? What are the effects of the superimposed diffuse and localized discrete auroral electron precipitation on the inner magnetospheric electric field and particle transport? To address SQ1, a coupling of three models will be used: (1) the magnetically and electrically self-consistent Rice Convection Model-Equilibrium (RCM-E) that calculates inner magnetospheric particle transport and precipitation due to the effect of wave-particle interactions, (2) the Superthermal Electron Transport (STET) model that will modify the RCM-E precipitating electron fluxes to include the effects of backscatter and multiple reflections between conjugate hemispheres, and (3) results from the B3C auroral transport model that computes altitudinal profiles of conductivity. To address SQ2, parameterized representative Gaussian auroral electron distributions will be used with STET and the B3C model to compute ionospheric conductivity. Observations such as ground-based photometers and All Sky Imaging data will be used to constrain the integrated electron energy flux, and the average energy of the discrete auroral precipitation will be parameterized. Simulations will be performed to include the conductance and potential drops associated with the discrete aurora in a localized region overlapping the broader diffuse aurora to investigate the effects on the inner magnetospheric particle transport.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.", "keywords": [], "approved": true } }, { "type": "Grant", "id": "12759", "attributes": { "award_id": "2143915", "title": "CAREER: Uncertainty Quantification for Quantum Computing Algorithms", "funder": { "id": 3, "ror": "https://ror.org/021nxhr62", "name": "National Science Foundation", "approved": true }, "funder_divisions": [ "Mathematical and Physical Sciences (MPS)", "FET-Fndtns of Emerging Tech" ], "program_reference_codes": [], "program_officials": [], "start_date": "2022-09-01", "end_date": null, "award_amount": 0, "principal_investigator": { "id": 28664, "first_name": "Xiu", "last_name": "Yang", "orcid": null, "emails": "", "private_emails": "", "keywords": null, "approved": true, "websites": null, "desired_collaboration": null, "comments": null, "affiliations": [] }, "other_investigators": [], "awardee_organization": { "id": 341, "ror": "https://ror.org/012afjb06", "name": "Lehigh University", "address": "", "city": "", "state": "PA", "zip": "", "country": "United States", "approved": true }, "abstract": "This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Quantum computing harnesses properties of quantum states to enable computations that would be intractable using classical computing. It is widely established that, in the future, quantum computing can revolutionize the way one performs and thinks about computation and serve as the backbone of groundbreaking new technologies for scientific discovery, engineering design, national security, and business development, to name a few. Currently, the key barrier in the development of quantum computing is the error induced by the noise in the hardware. The research goal of this project is to develop methods to model the error propagation in quantum computing algorithms and filter the resulting noise in the outcomes. This study will help enhance the performance of general quantum computing algorithms in terms of accuracy and efficiency. The educational goals of this effort are to prepare students for interdisciplinary research and promote STEM participation and equity among underrepresented groups. Outreach activities also involve K-12 students. The investigator will develop new uncertainty quantification methods in the following four directions to understand and alleviate the effect of noise on quantum computing algorithms: (1) describing propagation of gate error and readout error using epistemic uncertainty models; (2) mitigating errors using constrained optimization methods and Bayesian approaches; (3) analyzing asymptotic behavior of the propagation of the error; (4) developing an open-source software package to implement the uncertainty quantification algorithms. These new methods will leverage Bayesian inference approaches, tensor decomposition techniques, asymptotic analysis tools for stochastic differential equations, and high-performance computing packages to build the foundation of a \"quantum numerical analysis\" framework from a probabilistic perspective. This framework is general, and it can be used to assess the performance of real-world quantum processors and evaluate the suitability of specific quantum computing hardware architectures for a wide range of applications.

In this project, funded by the Mathematical and Physical Sciences Directorate and housed in the Chemistry Division, Professor Konstantin Bukhryakov and his students at the Florida International University will study the mechanism of olefin metathesis catalyzed by iron complexes. Olefin metathesis is the chemical reaction applied in industry to produce chemicals employed in daily life, including plastics, advanced materials, household chemicals, agricultural compounds, pharmaceuticals, and many others. The reaction requires the use of metal-based catalysts. However, the currently utilized catalysts are based on non-abundant metals, which affects the final cost of the products and raises environmental concerns. This research aims to develop catalysts for olefin metathesis based on iron, abundant and sustainable metal, to provide less expensive and greener alternatives for existing methods. This, in turn, will make essential chemicals more accessible to consumers and decrease the human environmental footprint. The project provides research opportunities for multiple high-school, undergraduate, and graduate students.The proposed research plan focuses on developing well-defined iron catalysts for olefin metathesis. The project will perform a comprehensive systematical study of the influence of ligands on the catalytic activity, selectivity, and stability of iron catalysts. It will allow the development of a reliable catalyst. Kinetic investigations of initiation, productive metathesis, decomposition steps will help identify the optimum catalytic conditions. In addition, studies of critical active intermediates and decomposition products will expand the scope of iron-based olefin metathesis.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.", "keywords": [], "approved": true } }, { "type": "Grant", "id": "12761", "attributes": { "award_id": "2213312", "title": "MPS-Ascend: From Directly Imaged Planets to Directly Characterized Planets: A Multi-pronged Approach to Understand Planet Formation Processes", "funder": { "id": 3, "ror": "https://ror.org/021nxhr62", "name": "National Science Foundation", "approved": true }, "funder_divisions": [ "Mathematical and Physical Sciences (MPS)", "ASCEND - MPS" ], "program_reference_codes": [], "program_officials": [], "start_date": "2022-09-01", "end_date": null, "award_amount": 0, "principal_investigator": { "id": 28666, "first_name": "Raquel", "last_name": "Martinez", "orcid": null, "emails": "", "private_emails": "", "keywords": null, "approved": true, "websites": null, "desired_collaboration": null, "comments": null, "affiliations": [] }, "other_investigators": [], "awardee_organization": { "id": 2154, "ror": "", "name": "Martinez, Raquel Angelina", "address": "", "city": "", "state": "CA", "zip": "", "country": "United States", "approved": true }, "abstract": "This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).

The host institution for the fellowship the University of California, Irvine (UCI), and the sponsoring scientist is Dr. Steph Sallum. This proposal will advance understanding of the origin, evolution, and demographics of gas giant exoplanets and wide-orbit planetary-mass companions (PMCs). Current theories of planet and star formation are unable to explain the observed characteristics of PMCs largely because of inadequate statistics. The proposer will reveal the dominant formation pathways of PMCs by efficiently building the wide-orbit planetary-mass and substellar companion sample, then pursuing detailed observational followup of new and known wide companion discoveries.

The conventional way of growing most of the world’s crops is to apply reduced forms of nitrogen as fertilizer. Although it promotes crop yields, much of the fertilizer leaches out into groundwater, streams, and oceans, causing severe ecological disturbances, including overgrowth of plant life, oxygen depletion, and death of animal life. Due to overuse, more than 500 sites of coastal waters worldwide are now declared ‘dead zones’. A group of soil bacteria collectively known as rhizobia can reduce (fix) nitrogen. Legumes establish mutually beneficial associations (symbioses) with compatible rhizobia, by allowing their selective entry into newly developed organs (root nodules), thus acquiring an internal source of fertilizer. Nitrogen fixation efficiency varies in different legume-rhizobia associations; therefore, for high yields, fertilizer nitrogen needs to be applied on legume crops. This shuts down symbiotic nitrogen fixation (SNF). The project seeks to uncover new mechanisms of host-strain specificity to improve SNF efficiency, informing the development of crop varieties and engineered bacterial strains that can enhance the economic potential of SNF for low-input, sustainable agriculture. Research activities from this project will be integrated into an inquiry- and project-based revamped graduate course-lab, and into various educational activities including training of undergraduate and graduate students, a postdoctoral researcher, and training disadvantaged middle- and high school girls from rural Texas. An intriguing aspect of SNF is host-strain specificity, critical for efficient nitrogen fixation, but, still, poorly understood at the genetic and the molecular level. Because the rhizosphere contains multiple rhizobial strains at any time, it is critical for a legume host to distinguish between friend and foe, and, also, to distinguish between efficient and less efficient friends, for optimal nitrogen fixation. The proposed research builds on the hypothesis that the Medicago truncatula MtNPD1 gene (nodule-specific polycystin-1, lipoxygenase, alpha-toxin domain-containing protein) orchestrates rhizobial selection in order to maintain effective nitrogen fixation in root nodules. The host-strain specific phenotype of the npd1 mutant implies that MtNPD1 may be interacting with certain bacterial factors to promote survival and normal function of compatible strains inside root nodules. An assortment of molecular, genetic, proteomic, genomic, and microscopic approaches will be used to decipher the biological roles of MtNPD1 and the other four members of this nodule-specific gene family. The main goals of the project are to identify plant and/or bacterial protein partners of MtNPD1, refine intracellular MtNPD1 localization in a strain-dependent manner, and identify bacterial factors linked to the NPD1 gene function and host-strain specificity using pan-genome analysis and genomic library switching between strains with contrasting fate in npd1 nodules. Altogether, the proposed work is poised to enhance our understanding of how M. truncatula selects favorable symbiotic partners, thus optimizing SNF with specific rhizobial strains.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.", "keywords": [], "approved": true } }, { "type": "Grant", "id": "12763", "attributes": { "award_id": "2212736", "title": "MPS-Ascend: Understanding Khovanov Homology Through Configuration Spaces", "funder": { "id": 3, "ror": "https://ror.org/021nxhr62", "name": "National Science Foundation", "approved": true }, "funder_divisions": [ "Mathematical and Physical Sciences (MPS)", "ASCEND - MPS" ], "program_reference_codes": [], "program_officials": [], "start_date": "2022-09-01", "end_date": null, "award_amount": 0, "principal_investigator": { "id": 28668, "first_name": "Gabriel", "last_name": "Montoya-Vega", "orcid": null, "emails": "", "private_emails": "", "keywords": null, "approved": true, "websites": null, "desired_collaboration": null, "comments": null, "affiliations": [] }, "other_investigators": [], "awardee_organization": { "id": 2155, "ror": "", "name": "Montoya-Vega, Gabriel Jaime", "address": "", "city": "", "state": "DC", "zip": "", "country": "United States", "approved": true }, "abstract": "This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).

This dearth of samples has led to vigorous debate amongst the geological community regarding three very important aspects of Earth evolution: 1) when, 2) how, and 3) to what extent did continents emerge on the early Earth. Recent advances in technical capabilities now allow these questions to be revisited. Earth is a tectonically active planet, which means that old rocks are constantly being altered, leaving few pristine samples from the earliest phases of Earth history. By looking for very small, but important isotopic signatures in preserved rock samples, one may infer how much continental crust was around very early in Earth history. This project will fund advanced isotopic analyses of ~2.6-billion-year-old rocks in a search of evidence for great than 4.0-billion-year-old continental material, material that may have been reworked during later tectonic events. Collection of this data will allow the research team to test the hypothesis that very large volumes of ancient continental crust existed on the early Earth and to answer a fundamental question about planetary formation and evolution – when did continental crust form on Earth? This project will also support an undergraduate field research experience, which will serve to train the next generation of geoscientists in skills that employers are keenly interested in – field geology and spatial reasoning skills.This proposal will combine petrology and isotope geochemistry to test broad hypotheses regarding the growth and reworking of continental crust. Neoarchean granitoid rocks represent some of the oldest well-preserved suites of rocks on Earth. Detailed analysis of samples will address the fundamental question of when continental crust formed on Earth. This proposal will analyze suites of granitoids from three distinct North American cratons for their igneous chemical signatures. Zircon age and isotopic information (U-Pb-Hf-O) will be measured from several compositional groups to test the fidelity of commonly used tracers for crustal melting and overprinting. Analyses of xenocrystic zircons and bulk rock Nd-isotope ratios will be used to search for reworking of truly ancient (>4.0 Ga) crust in the Neoarchean—a time that has been suggested to have experienced broad overprinting of the continental record. The research team focus on 142Nd analyses as these data are particularly adept at identifying Hadean crustal relics. This proposal will fund an REU field experience aimed at developing a diverse and strategically important workforce with training in field geology and spatial reasoning. The maps created and samples collected by undergraduate researchers will be used for advanced isotopic analyses conducted during the scientific study, and undergraduate participants will not only gain important—and in-demand—skills in spatially-focused critical thinking but will also be exposed to advanced geochemical techniques and datasets.

The springs store large amounts of energy for even bigger jumps. A microrobot the same size as an insect that can jump to heights over ten times its own body length has the potential to explore unknown and changing environments, such as subterranean caves, disaster rubble, or even the surface of other planets.This project will create jumping microrobots that will reach new levels of control and autonomy. This work will create a mathematical and experimental framework that uncovers how energy is released by a latch. This framework will connect features of robot design with control to push the boundaries of autonomy in jumping microrobots. The huge leaps in small robots make this project an excellent candidate for outreach activities in robotics research. Undergraduate researchers will be recruited through a project portal at the University at Buffalo that provides equitable access to research opportunities to a diverse student population across the university. The research plan in this project works toward the principled design of jumping microrobots with controllable jump heights, a part of the latch-mediated spring actuation (LaMSA) framework. In this framework, springs are loaded but blocked by a latch, and the jump occurs when the latch is removed. Control in jumping robots has largely been through spring loaded, but this project focuses on understanding the dynamics of unlatching as a new axis of control in jumping microrobots. This is particularly important for the incredibly fast time scales of spring actuation. First, a thorough understanding of the dynamics of unlatching will be elucidated through mathematical and physical models. A new understanding of the dynamics of unlatching will become a pathway for control in jumping microrobots, to either produce the same, stereotyped jumping behavior with different initial conditions, or variable behavior with the same initial conditions. These research efforts will be a pathway toward a general understanding of dynamics and control of unlatching, and lead to a principled framework for the design and control of jumping microrobots.This project is supported by the cross-directorate Foundational Research in Robotics program, jointly managed and funded by the Directorates for Engineering (ENG) and Computer and Information Science and Engineering (CISE).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.", "keywords": [], "approved": true } }, { "type": "Grant", "id": "12766", "attributes": { "award_id": "2204149", "title": "Modeling Long-Term Urban and Rural Settlement Dynamics", "funder": { "id": 3, "ror": "https://ror.org/021nxhr62", "name": "National Science Foundation", "approved": true }, "funder_divisions": [ "Social, Behavioral, and Economic Sciences (SBE)", "(SPRF-FR) SBE Postdoctoral Res" ], "program_reference_codes": [], "program_officials": [], "start_date": "2022-09-01", "end_date": null, "award_amount": 0, "principal_investigator": { "id": 28671, "first_name": "Carla", "last_name": "Klehm", "orcid": null, "emails": "", "private_emails": "", "keywords": null, "approved": true, "websites": null, "desired_collaboration": null, "comments": null, "affiliations": [] }, "other_investigators": [], "awardee_organization": { "id": 2156, "ror": "", "name": "Alders, Wolfgang", "address": "", "city": "", "state": "CA", "zip": "", "country": "United States", "approved": true }, "abstract": "This award was provided as part of NSF's Social, Behavioral and Economic Sciences (SBE) Postdoctoral Research Fellowships (SPRF) program. The goal of the SPRF program is to prepare promising, early career doctoral-level scientists for scientific careers in academia, industry or private sector, and government. SPRF awards involve two years of training under the sponsorship of established scientists and encourage Postdoctoral Fellows to perform independent research. NSF seeks to promote the participation of scientists from all segments of the scientific community, including those from underrepresented groups, in its research programs and activities; the postdoctoral period is considered to be an important level of professional development in attaining this goal. Each Postdoctoral Fellow must address important scientific questions that advance their respective disciplinary fields. Under the sponsorship of Dr. Carla Klehm at the University of Arkansas, Fayetteville, this postdoctoral fellowship award supports an early career scientist studying urban-rural dynamics. This project investigates the social processes of urbanization within a regional settlement system. It advances scientific knowledge on these aspects of human social and organizational behavior through a long-term archaeological study. This research contributes to general knowledge about rural and urban social change by investigating the spatial settlement patterns of communities which differentiated themselves from urban institutions and negotiated with the centralization of power in urban centers. How small human groups related socially to the emergence of urban formations has been an important anthropological question with implications for understanding long-term sustainability and resilience. However, most research has used examples from primary centers of urban formation globally. In contrast, this research deepens an understanding of urban-rural interaction through a consideration of large urban centers over the long-term. The results of this research will inform general understandings of human adaptations to social transformation and political instability globally.This project uses archaeological methods and geospatial analyses to understand the spatial and material relationships between rural communities and large urban settlements, from the 11th to 19th centuries CE. The extent to which urbanization meant the (dis)integration or subordination of indigenous rural social networks is unresolved, as are the ways rural communities related to the social world. This research will refine models of global urbanism by investigating rural settlement dynamics in relation to urban development over time. The project asks, to what extent were rural communities entangled economically and materially with town dwellers, and how did urban-rural settlement dynamics change from the precolonial period, through colonial contact, and into the 19th century? This project uses low-cost, high-resolution aerial and multispectral satellite imagery to create a predictive model for rural site distribution, integrating historical maps, textual sources, hydrological models, geological data, and automated object-based image analysis of drone imagery to detect cultural significant features. Next, the project uses this model to develop a targeted survey of the urban hinterland. Finally, test excavations will be used to compare material culture from rural hinterland sites with already excavated collections from urban centers. This will enable an understanding of the spatial and material patterns across time and in relation to urban centers.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.", "keywords": [], "approved": true } }, { "type": "Grant", "id": "12767", "attributes": { "award_id": "2238340", "title": "CAREER: An Integrated Geophysical Approach to Research and Education to Solve the Tectonic Puzzle of the Northern Atlantic", "funder": { "id": 3, "ror": "https://ror.org/021nxhr62", "name": "National Science Foundation", "approved": true }, "funder_divisions": [ "Geosciences (GEO)", "Marine Geology and Geophysics" ], "program_reference_codes": [], "program_officials": [], "start_date": "2023-03-01", "end_date": null, "award_amount": 0, "principal_investigator": null, "other_investigators": [], "awardee_organization": { "id": 298, "ror": "", "name": "University of Nebraska-Lincoln", "address": "", "city": "", "state": "NE", "zip": "", "country": "United States", "approved": true }, "abstract": "The Northern Atlantic has diverse geologic features including a hotspot under Iceland, volcanic-rich passive continental margins of Norway and Eastern Greenland, and active and abandoned spreading centers in the Atlantic Ocean with the Jan Mayen microcontinent in between. However, the tectonic history of the region has generally been oversimplified. This research will reveal the crustal type (continental or oceanic) of different tectonic blocks, reconstruct their fit prior to the opening of the northern Atlantic Ocean, and provide a tectonic “snapshot” for each geologic time period. The results can help pinpoint the timing and extent of critical geological processes that affect paleoclimate, biodiversity, and initiation of oceanic water circulation. The research will be integrated with education efforts, including mini research projects in advanced geophysical classes at the University of Nebraska-Lincoln; a summer camp for high school students and underserved students from Girls Inc. of Lincoln and Omaha, NE; and five education modules that will be disseminated to educators across the nation via the Science Education Resource Center at Carleton College. Such efforts will broaden participation in STEM and cultivate a diverse and well-equipped geophysics workforce. With uncertainties in the extent of the Jan Mayen microcontinent and tectonic domains of the Norwegian margin, as well as the disputed crustal affinity of the Greenland-Iceland-Faroe Ridge, tectonic reconstruction of the Northern Atlantic region remains poorly constrained. This project will examine crustal architecture and tectonic structures of individual regions via the integration of geophysical methods with geological constraints from scientific drilling. A set of robust and comprehensive geophysical models in three individual regions of the Northern Atlantic – the Norwegian-Greenland conjugate margins, the Jan Mayen microcontinent, and the Greenland-Iceland-Faroe Ridge region – will be developed to define subsurface structures that are in agreement with multiple geophysical methods. The identified tectonic features will be traced in-between the modeled lines in all three regions using spatial analysis of potential fields, building a framework for a consequent tectonic restoration, which will provide new fundamental knowledge of the pre-Atlantic continent. Integrated with these efforts, the education goal is to promote geophysics as a career of choice by engaging diverse undergraduate, graduate, and high school students in interactive learning experiences centered around an integrated geophysical approach. These activities will promote a comprehensive multi-physics analysis that integrates publicly available datasets and enables robust and rigorous interpretations. Ultimately, a comprehensive geophysical research program will be established at a public land-grant institution that will yield graduates who are well-equipped to meet the needs of the geophysical workforce and nation.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.", "keywords": [], "approved": true } } ], "meta": { "pagination": { "page": 1384, "pages": 1405, "count": 14046 } } }
