Soil microbes are important for maintaining agricultural ecosystems by promoting nutrient cycling, plant growth, and soil resilience. Microbial-based inoculants, such as bio-inoculants and bioremediation agents, have been identified as suitable means to promote soil health, reduce environmental deterioration, and achieve sustainable agriculture. Bio-inoculants, such as biofertilizers and biopesticides, promote nutrient availability, plant growth, and chemical input dependency reduction. Diverse microbial populations, especially plant growth-promoting bacteria (PGPB), enhance resistance by promoting a symbiotic association with plants and inducing natural resistance against insects. Bioremediation, the second significant microbial intervention, is the use of microorganisms for detoxifying and rehabilitating polluted soils. Methods effectively …

Dictyostelids: The Second Major Group Of Slime Molds, P. Liu, Z.J. Zhang, J.H. Ge, Y. Zou, Z. Li, S. Li, Y. Li, S.L. Stephenson

Biological Sciences Faculty Publications and Presentations

The dictyostelids (also called cellular slime molds or social amoebae) are among the more abundant and widespread groups of microorganisms in terrestrial ecosystems. Despite this fact, they are totally unknown to most people, who sometimes confuse the dictyostelids with myxomycetes (or plasmodial slime molds). The first dictyostelid (Dictyostelium mucoroides) was described by the German Oskar Brefeld in 1869. More than 180 species are now known, and these organisms have been recorded from the high arctic to the subantarctic. The primary microhabitat for dictyostelids is the soil/humus layer on a forest floor, but they also occur in a number of other …

Efficient Discovery Of Frequently Co-Occurring Mutations In A Sequence Database With Matrix Factorization, Michael Robert Kolar, Debasis Mitra, Valerie Kobzarenko Jan 2025

Efficient Discovery Of Frequently Co-Occurring Mutations In A Sequence Database With Matrix Factorization, Michael Robert Kolar, Debasis Mitra, Valerie Kobzarenko

Electrical Engineering and Computer Science Faculty Publications

We have developed a robust method for efficiently tracking multiple co-occurring mutations in a sequence database. Evolution often hinges on the interaction of several mutations to produce significant phenotypic changes that lead to the proliferation of a variant. However, identifying numerous simultaneous mutations across a vast database of sequences poses a significant computational challenge. Our approach leverages a matrix factorization technique to automatically and efficiently pinpoint subsets of positions where co-mutations occur, appearing in a substantial number of sequences within the database. We validated our method using SARS-CoV-2 receptor-binding domains, comprising approximately seven hundred thousand sequences of the Spike protein, …


Highly Scalable Solid-Core Inhibited-Coupling Fiber-Based Plasmonic Refractive Index Sensor, Mohammad Al Mahfuz, Md Selim Habib Jan 2025

Highly Scalable Solid-Core Inhibited-Coupling Fiber-Based Plasmonic Refractive Index Sensor, Mohammad Al Mahfuz, Md Selim Habib

Electrical Engineering and Computer Science Faculty Publications

Advancements in plasmonic sensing require simultaneous detection capability that ensures large-scale detection with reduced losses. In this work, we propose a new solid-core fiber-based refractive index (RI) sensor with an ultra-broad detection range. The proposed fiber consists of a relatively simple single-ring cladding with six circular tubes in which the light is guided in the core based on the inhibited-coupling (IC) mechanism. The sensing performance is investigated using extensive finite-element modeling (FEM) through the combination of IC and surface plasmon resonance (SPR) sensing technology. Our results show a low loss of <3 dB/cm across the RI detection range from 1 to 1.60, peaking the wavelength sensitivity (WS) of 3000 nm/RIU and figure of merit (FOM) of 120 RIU−1. Our study also includes the investigation of the fabrication tolerance, fiber bending, and the use of alternative plasmonic materials, providing insights into the practical implementation capability of the proposed sensor. Our findings highlight the potential of the proposed sensor in emerging applications such as detecting air pollutants, biochemical substances, and DNA, paving the way towards bio-sensing within a lab-on-a-chip platform. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

Towards The Application Of Graphrag To Network Security, Marco Carvalho, Fitzroy Nembhard, Dhanish Mehta

Electrical Engineering and Computer Science Faculty Publications

The adoption of large language models (LLMs) has facilitated significant advancements in natural language processing. In a short space of time, LLMs have permeated a wide array of disciplines including healthcare, finance, education, etc. However, in their native form, LLMs retain information in their parameters, which sometimes causes the underlying models to produce inaccurate results or hallucinations. To that end, Retrieval-Augmented Generation (RAG) has been proposed to address some of the challenges of LLMs by referencing an external knowledge base while formulating a response to queries. Still, traditional RAG fails to handle the complex structure of relationships among different entities …

Iowa Journal of Communication

This study examined the effects of image-based assignment of agency (IAA) on COVID-19 and flu fear-appeals by employing eye-tracking technology. Volunteers participated in a 2x2x2 between-groups experiment. Fixation-count and fixation-duration were collected by a Tobii Pro X3-120 Screen-Based Eye-Tracker. After reviewing a fact sheet, participants answered a 29-item survey that included items aligning with the extended parallel process model. The flu/agentic-image/virus-agentic-language message produced significantly higher fixation-frequency to the image and a higher perception of severity than the COVID-19/real-image/human-agentic-language message. Fixation-frequency on the image produced significantly higher fear perceptions, but significantly lower message-quality and message-credibility perceptions. Flu messages led to significantly …

This study explores the therapeutic potential of Calligonum comosum extract in alleviating pregabalin (PGB)-induced toxicity in male Wistar rats, with a focus on hepatic, renal, and reproductive health. PGB exposure led to significant biochemical disturbances, including elevated liver enzymes (AST, ALT, LDH), impaired kidney markers (urea, creatinine, uric acid), reduced reproductive hormones (testosterone, FSH, LH), and notable histopathological damage in liver, kidney, and testicular tissues. Treatment with C. comosum extract effectively restored liver and kidney functions and partially corrected hormonal imbalances. The extract reduced AST, ALT, and LDH levels by 18.5%, 25.2%, and 13.7%, respectively. Similarly, urea, creatinine, and uric …


Consciousness Of Octopuses—On Their Own Terms, Jennifer Mather Jan 2025

Consciousness Of Octopuses—On Their Own Terms, Jennifer Mather

Animal Sentience

Because cephalopods are so different from the vertebrate lineage, their possible consciousness must be assessed on the basis of their heritage and abilities. Cephalopods have evolved in water, a denser medium than air, and their perception is adapted to it. They have inherited the molluscan mantle cavity and hydrostatic muscle type, which has led to a more distributed motor control system despite a centralized brain, and have evolved a completely novel skin display system. Using these abilities, octopuses can form concepts, plan for the future, generate a cognitive map, and self-monitor for apparent pain and manipulate communication. Most cephalopods use …


Words And Stardom: Modernist Poetic Responses To Asta Nielsen, Karl E. Toepfer Jan 2025

Words And Stardom: Modernist Poetic Responses To Asta Nielsen, Karl E. Toepfer

Open Educational Resources

This essay discusses how four modernist poets portrayed the Danish movie star Asta Nilesen (1881-1972). German Hans Schiebelhuth (1895-1944) describes the "demonic" power of Nielsen's image to awaken dark aspects of his adolscent personality. For the Flemish poet Paul van Ostaijen (1896-1928), Nielsen's cinematic image provokes a radical shattering of language into extravagant "word-images." Danish writer Rudolf Broby-Johansen (1900-1987) linked Nielsen's image to a radical (Marxist) critique of oppressive sexual politics within a capitalist society. German Franz Behrens (1895-1977) composed a lengthy, expressionist ode to Nielsen from the perspective of one who actually worked as a screenwriter in the German …

Applied Environmental Research

This study identified Bacillus cereus, an efficient Cr(VI) bioreducer, isolated from marine sediment in Thailand. Batch experiments verified the complete removal of 25 mg L-1Cr(VI) from synthetic wastewater (pH 7.0) after 6 days at 37 °C, 50 rpm,and a biomass concentration of 25% (v/v) culture inoculum. The Freundlich isotherm model demonstrated the best correlation with the Cr(VI) adsorption equilibrium data in the 25–100 mg L-1concentration range (R2= 0.9831). Kinetic analyses indicated that the removal of Cr(VI) by living B. cereusfollowed a pseudo-second-order adsorption model (R2= 0.9875) and a pseudo-second-order reduction model (R2= 0.9807). The adsorption rate can be accuratelycharacterizedvia the …


Patent Infringement In Time, John R. Thomas Jan 2025

Patent Infringement In Time, John R. Thomas

Georgetown Law Faculty Publications and Other Works

No patent lasts forever. When intellectual property rights expire, a canonical principle states, all benefits of their ownership cease. But patents may cast a long shadow after they are gone, hindering the advent of immediate competition upon their expiration. The law acts unevenly in these circumstances, leading to questionable intellectual property and public health policies. Ordinarily competitors cannot make and use a patented invention until the patent's term has concluded. This delay ordinarily extends the effective period of exclusivity that the patentee enjoys. However, a statutory safe harbor shields from infringement acts undertaken "solely for uses reasonably related" to Food …

Optical Coherence Tomography Harmonization With Anatomy-Guided Latent Metric Schrödinger Bridges, Shuwen Wei, Blake E. Dewey, Samuel W. Remedios, Bruno Jedynak, Shimeng Wang, Peter Calabresi, Shiv Saidha, Aaron Carass, Multiple Additional Authors

Mathematics and Statistics Faculty Publications and Presentations

Medical image harmonization aims to reduce the differences in appearance caused by scanner hardware variations to allow for consistent and reliable comparisons across devices. Harmonization based on paired images from different devices has limited applicability in real-world clinical settings. On the other hand, unpaired harmonization typically does not guarantee anatomy consistency, which is problematic because anatomical information preservation is paramount. The Schrödinger bridge framework has achieved state-of-the-art style transfer performance with natural images by matching distributions of unpaired images, but this approach can also introduce anatomy changes when applied to medical images. We show that such changes occur because the …

Mock: An Algorithm For Learning Nonparametric Differential Equations Via Multivariate Occupation Kernel Functions, Victoria A. Rielly, Kamel Lahouel, Ethan Lew, Nicholas Fisher, Vicky Geneva Haney, Michael Wells, Bruno M. Jedynak

Mathematics and Statistics Faculty Publications and Presentations

Learning a nonparametric system of ordinary differential equations from trajectories in a -dimensional state space requires learning functions of variables. Explicit formulations often scale quadratically in unless additional knowledge about system properties, such as sparsity and symmetries, is available. In this work, we propose a linear approach, the multivariate occupation kernel method (MOCK), using the implicit formulation provided by vector-valued reproducing kernel Hilbert spaces. The solution for the vector field relies on multivariate occupation kernel functions associated with the trajectories and scales linearly with the dimension of the state space. We validate through experiments on a variety of simulated and …

The Forms Of Representation: How To Be A Kantian Realist, Willem A. Devries

Faculty Publications

Sellars argued that Kant did not make certain distinctions concerning space and time, and because of this adopted his transcendental idealism. Once these distinctions are made, the path to realism remains open. Sellars' argument is not entirely clear. This essay attempts to clarify the argument, showing why Sellars believed he could remain a scientific realist while also adopting a Kantian style epistemology.

“Finally Girls Hitting A Celly:” Emotions And Gender Embodiment In Competitive Swimmers’ Post-Race Celebrations, Lauren Q. Rohde , '25

Senior Theses, Projects, and Awards

In athletic competitions, the moment of achievement is often extremely cathartic and results in a visible celebration. In competitive swimming, these reactions to success are isolated to the end of a race, completely individual, and often feature interaction with one’s surroundings, such as the water or lane lines. These moments are also highly visible and usually well-photographed, and the visibility of these actions contributes to a growing culture in the sport around post-race celebrations. The exposure of the body in competitive swimming additionally contributes to its visibility, further complicating behaviors and norms around celebrating race outcomes. This research aims to …

School of Medicine Faculty Publications

This study focuses on the effect of Environmentally Persistent Free Radicals (EPFRs) on the P450 enzymes of the CYP1 family. EPFRs are a component of particulate pollutants, that are stable in the environment, but can generate free radicals, leading to oxidative stress and subsequent toxicity of the respiratory, cardiovascular, and immune systems once they enter an organism. The results show differences in the ability of EPFRs to inhibit CYP1-dependent substrate metabolism, with CYP1B1 being inhibited to the greatest extent. There also were differences in the ability of EPFRs to disrupt the POR•CYP1 complex, with CYP1B1 being the only form where …
