Vacant to Vibrant: Adaptive Reuse Opportunities in Prince George’s County, Maryland
No full textFinal report for PLCY400: Senior Capstone (Spring 2025). University of Maryland, College ParkPrince George’s County, Maryland, faces a growing crisis of vacant and underutilized properties, contributing to urban decline, declining property values, and, increasingly, safety concerns. Legal barriers, high redevelopment costs, and limited coordination across agencies have hindered efforts to transform these properties despite the county’s commitment to sustainability and infrastructure development. This report explores adaptive reuse as a sustainable and community-centered solution for property revitalization in the Capitol Heights/Blue Line Corridor area. It asserts that adaptive reuse can convert underutilized commercial spaces into mixed-use residential developments that revitalize neighborhoods and support equitable and sustainable growth. The analysis highlights promising strategies such as transit-oriented development, flexible zoning policies, and addressing challenges such as regulatory and financial limitations and gentrification. Finally, we outline a redevelopment guidebook that offers strategic, replicable, and equity-focused recommendations to support middle-income housing, small-scale development, and more effective land use.Prince George's County, M
ANALYZING TRENDS IN BENTHIC MACROFAUNAL BIODIVERSITY IN THE PACIFIC ARCTIC THROUGH TAXONOMINC AND GENOMIC METHODS
No full textTrends and environmental parameters that can influence benthic macrofaunal biodiversity were examined at sites in the Distributed Biological Observatory, a group of time-series stations located in the biologically productive shallow Pacific Arctic shelf region. This goal of this study was to better understand the underlying drivers of biodiversity and connectivity, which are important for predicting regional ecosystem resiliency to future warming, especially as sea ice loss and seawater warming have impacted seasonal water column production, carbon export to the benthos, and benthic faunal community structure and composition. A mixed-effects regression analysis was undertaken on taxonomically-based Shannon Index macrofaunal data from 1998-2019 to identify the region-wide environmental parameters influencing benthic macrofaunal biodiversity and any temporal and spatial patterns of variability. An index of the heterogeneity of sediment grain size classes, representing niche space, was found to positively influence biodiversity at both regional and sub-regional scales. There were few temporal trends in sediment heterogeneity, yet both positive and negative biodiversity trends persisted at specific locations, related to other environmental parameters. Specifically, the length of seasonal sea ice persistence influenced biodiversity, but with some regional complexities.
A phylogeographic analysis of three benthic macrofaunal species from the northern Bering and Chukchi Seas was conducted using cytochrome c oxidase (CO1) barcode data. The study examined two clam species, Ennucula tenuis (Montagu, 1908) and Macoma calcarea (Gmelin, 1791), along with the polychaete Cistenides hyperborea (Malmgren, 1866), to investigate population-level genetic connectivity in these seasonally productive, shallow-shelf ecosystems. Genetic barcode data were compared with sequences in National Center for Biotechnology (NCBI) from other studies across the Arctic to assess broader population dynamics. E. tenuis specimens belonged to a single population with distinct geographic variation. Analysis of M. calcarea was inconclusive due to technical problems during sample processing that prevented developing a population structure assessment prior to completing this thesis. C. hyperborea specimens from the northern Bering and Chukchi Seas formed a single population with two closely related haplotypes and minimal geographic genetic differentiation. However, sequences from this study differed significantly from Cistenides hyperborea records in the NCBI, suggesting there may be have taxonomic uncertainties associated with available data in the NCBI
quantum simulation with waveguide photons: theory and experiment
No full textRecently, waveguide photons have emerged as a versatile platform for the simulation quantum dynamics. So far, the majority of works in this field have been limited to the non-interacting regime, and intriguing nonlinear and interactive quantum many-body phenomena such as Bose-Hubbard or fractional quantum Hall (FQH) physics have remained elusive for this particular platform. In this thesis, we present both experimental work that demonstrates the versatility of the waveguide photonic platform as well as theory works that aim to introduce strong photon-photon interactions.For the experiment, we demonstrate a dynamically controllable non-Hermitian quantum walk using the waveguide photonic platform. For the first theory work, we introduce a two level atom beamsplitter and use this nonlinear beamsplitter to study a quantum walk with strong interaction. For the second ensemble of theory work, we first establish a general framework for bosonic quantum many-body Hamiltonian simulation using waveguide photons, and show that a tunable “on-site interaction” can be simulated using a photon number selective phase gate. Specifically, we proposed a concrete architecture for such a phase gate based on a three-level-atom-mediated photon subtraction and addition. We showcase the effectiveness of our Hamiltonian simulation framework with concrete examples including the Bose-Hubbard model and fractional quantum Hall model. Moreover, we present the probing and preparation scheme of the ground state of the FQH model by simulating certain Lindbladians under the same simulation framework. Our theoretical proposal opens a novel and scalable avenue to explore intriguing phenomena in strongly interacting many-body physics such as FQH states of light, non-Abelian braiding and statistics and beyond
Identity Documents and Trans People in Maryland: Experiences with Name and Gender Markers
No full textThe Maryland Trans Survey is a community-based research project conducted by Trans Maryland and the Queer/Trans Collective for Research on Equity and Wellness examining experiences of trans people in the State of Maryland in areas such as health and healthcare, employment and economic wellbeing, and legal and policy experiences. To date, it is the largest survey of trans people in the State, with 750 trans people representing all 23 counties in Maryland and Baltimore City. Data were collected from June to December 2023 through in-person and online community outreach. The project was approved by Towson University’s Institutional Review Board (Protocol #1897) and used Transgender Research Informed Consent (TRICON) Disclosures to provide trans community members with additional transparency on the project, recognizing long histories of harmful practices in trans research from scientific institutions. This brief contains information from the survey related to name and gender on identity documents to help advocates, policymakers, and community-serving entities better understand and support the current needs of trans people in Maryland.University System of Maryland - Wilson H.

How “Race” Is Used in U.S. Peer-Reviewed Studies of Cardiovascular Health and Cardiorespiratory Fitness: A Scoping Review
No full textIn this scoping review, we examine whether and how race is used to explain differences in cardiorespiratory fitness (CRF) and/or cardiovascular health (CVH) among racial/ethnic populations living in the United States in peer-reviewed research. Searching eight databases from their inception, and informed by the Population, Concept, and Context framework, our search yielded 232 studies (N = 232) published in English. Seventy-eight percent of included studies (n = 181) did not define race; 45% (n = 105) positioned White participants as the standard for CVH and CRF metrics, and only 7% (n = 17) of the studies used sociocultural explanations to discuss possible mechanisms of racial differences in CRF and CVH outcomes. Findings are interpreted as an indication of how “white logic” informs research pertaining to CRF and CVH. A series of recommendations are provided to help kinesiological scholars avoid reductionist characterizations of “race” through their research, thus better aligning with the National Academy of Kinesiology’s social justice mission.https://doi.org/10.1123/kr.2024-004
Radio Occultation Web Page Development
No full textThis report was written at the completion of the 2025 CISESS Summer Internship Program.Global Navigation Satellite System Radio Occultation (GNSS-RO) is an important remote sensing technique for weather forecasting, climate monitoring, and ionospheric research. Within this data ecosystem, the NOAA STAR GNSS-RO webpage serves a critical role as the primary provider of up-to-date GNSS-RO data for, but not limited to, the NOAA National Centers for Environmental Prediction (NCEP) Weather Prediction Center, the Joint Center for Satellite Data Assimilation (JCSDA), and the European Centre for Medium-Range Weather Forecasts (ECMWF). The work detailed in this paper thus focuses on reinforcing the continued reliability of the site while also expanding it with new functionality to better serve users. These changes include better routing and a new multi-graph view for the Integrated Calibration/Validation System (ICVS) pages, a new monthly mean humidity anomaly (MMHA) page, tooling to analyze downloaded product statistics, and the implementation of the Ground Tracker application. The primary focus of the paper, the Ground Tracker application, is a web-based tool for plotting and interacting with large quantities of GNSS-RO profiles. Users are able to visualize the position of the profiles on a 2D (equirectangular) and 3D (globe) projection, view profile metadata (such as time, quality, LEO altitude, etc.), and compare profiles based upon GNSS ID, mission name, penetration depth, SNR value, and quality. Profile data is automatically populated from the PlanetiQ, COSMIC-2, and Spire missions and the GPS, GLONASS, GALILEO, and BEIDOU GNSS systems from July 2025 onwards. This work ensures that the Radio Occultation webpage remains a useful and important component of the GNSS-RO data ecosystem.This study was supported by NOAA grant NA24NESX432C0001 (Cooperative Institute for Satellite Earth System Studies - CISESS) at the University of Maryland/ESSIC

Aptamer Selection for DNA Aptamers against Glioblastoma Biomarker
No full textGlioblastoma is an extremely invasive and deadly form of brain cancer, with median survival rates, after diagnosis, only being one year. Current diagnostics are extremely invasive and expensive. Our research goal is to select DNA aptamers with high-binding affinity to YKL-40, a biomarker found in urine, to allow for accessible and non-invasive diagnostics. The process of SELEX (Systematic Evolution of Ligands by EXponential enrichment) was used to find such an aptamer that binds strongly/specifically to YKL-40. From one round of successful selection, the amplification in both the bound and unbound pools showed a somewhat successful selection and potential specificity toward YKL-40, although, our team is determined to go through more rounds of SELEX to solidify these results. When we find an appropriate aptamer, it can be used to detect YKL-40
