As Earth's atmospheric temperatures and human populations increase, more people are becoming vulnerable to natural and human-induced disasters. This is particularly true in Central America, where the growing human population is experiencing climate extremes (droughts and floods), and the region is susceptible to geological hazards, such as earthquakes and volcanic eruptions, and environmental deterioration in many forms (soil erosion, lake eutrophication, heavy metal contamination, etc.). Instrumental and historical data from the region are insufficient to understand and document past hazards, a necessary first step for mitigating future risks. Long, continuous, well-resolved geological records can, however, provide a window into past …

Technologies capable of programmable translation activation offer strategies to develop therapeutics for diseases caused by insufficient gene expression. Here, we present "translation-activating RNAs" (taRNAs), a bifunctional RNA-based molecular technology that binds to a specific mRNA of interest and directly upregulates its translation. taRNAs are constructed from a variety of viral or mammalian RNA internal ribosome entry sites (IRESs) and upregulate translation for a suite of target mRNAs. We minimize the taRNA scaffold to 94 nucleotides, identify two translation initiation factor proteins responsible for taRNA activity, and validate the technology by amplifying SYNGAP1 expression, a haploinsufficiency disease target, in patient-derived cells. …

Patterns In Biodiversity And Community Assemblage In Macrofaunal Fouling Communities On Tampa Bay Floating Docks, Cassidy C. Bell

USF Tampa Graduate Theses and Dissertations

Understanding biodiversity trends of highly disturbed urban landscapes is essential as anthropogenic factors continue to drive global biodiversity loss. Within marine ecosystems, macrofaunal fouling communities, aggregations of epibenthic invertebrates that colonize human-made structures, represent an ecologically important subset of urban coastlines. Tampa Bay is a highly urbanized estuary in Florida, USA, and is home to the state’s largest port, Port Tampa Bay. This makes the bay a prime site for the introduction of new species, with many organisms either considered invasive or cryptogenic, their origins left unclear. Many factors may contribute to the communities that form on urban structures including …

Better understanding their extent throughout Earth’s oceans will aid in resource management and determining different factors which influence their formative factors and respective local characteristics. Multibeam bathymetry and backscatter data, along with auxiliary data suggest an area of seafloor near the Foundation Seamount chain in the southern Pacific Ocean, centered around -36.84° latitude, -119.75° longitude, contains a previously uncharted polymetallic nodule occurrence. Our analysis of Simrad EM12 DUAL (12 kHz) multibeam data, collected during a 1997 transit, shows an area of strong backscatter …

Discovery Of Small-Molecule Inhibitors For The Β-Catenin/B-Cell Lymphoma 9 Protein-Protein Interaction., Zilu Li

USF Tampa Graduate Theses and Dissertations

The Wnt/β-catenin signaling pathway is associated with activating genes that support cell proliferation, differentiation, and survival. Excessive activation of Wnt/β‐catenin signaling has been associated with development of several types of cancer and activation of stem-like cancer cells. Direct targeting of β‐catenin, the central hub in this signaling pathway, is a promising strategy to suppress the hyperactive β‐catenin signaling but has proven to be highlychallenging. Substantial efforts have been made to discover compounds that bind with β‐catenin, block β‐catenin mediated protein–protein interactions (PPIs) and suppress β‐catenin signaling. β‐catenin/BCL9 PPI has a smaller contacting area (1450 Å2) and a moderate binding affinity …

Seeing The Invisible: Projects On Flow Imaging From The Fluid Mechanics Lab, Keith Stein

Day of Scholarship

Shadowgraph and schlieren imaging are popular flow visualization techniques because, despite the straightforward setup and reliance on very simple geometrical optics principles, they provide powerful methods for capturing high-quality images of what would otherwise be invisible flow phenomena. Application of these methods along with high-speed video recording can reveal detailed pictures of fast flow events that may last for just a fraction of a millisecond. These techniques are being utilized in the Bethel Fluid Mechanics lab course (PHY423/ENR423) and in a number of student-faculty research projects. We present snapshots of a few recent student-faculty projects utilizing shadowgraph and schlieren imaging.

A New Algorithm For Determining Energy And Charge Deposition In Spacecraft Insulators, Brian P. Beecken

Day of Scholarship

Space if filled with highly energetic electrons, many of which originate from the sun. All earth satellites must have insulators. Unfortunately, the insulators absorb both the electrons and the energy that they are carrying. Once sufficient charge accumulates, it is released in a sudden and destructive pulse which can destroy the onboard electronics and solar panel. The depth of penetration of the electrons in the insulators varies with incident energy, flux, and material. Determining the deposition profiles is key to understanding and mitigating the threat to satellites.

Search For Pair Production Of Vector-Like Quarks In Cms Run 2 Data, Julie Hogan

Day of Scholarship

The Compact Muon Solenoid experiment (CMS) at the CERN Large Hadron Collider records proton-proton collision data in order to study the particles and forces that exist in very high energy conditions. The 2012 discovery of the Higgs boson was a triumph for the field of particle physics, but pointed toward the probably existence of unknown high-mass particles. Vector-like quarks (VLQs) are a possible type of high-mass fermions, and their decays to lighter particles create exciting detector signatures. This search utilizes deep machine learning to both identify decay products of VLQs in the detector and to separate potential signal events from …

Particle Discovery Lab For Education & Outreach, Julie Hogan

Day of Scholarship

The Compact Muon Solenoid experiment (CMS) at the CERN Large Hadron Collider records proton-proton collision data in order to study the particles and forces that exist in very high energy conditions. CMS releases data to the public after several years of internal analysis. This data has a rich history of use for middle school or high school education, but is not widely used by college students in the US. Bethel students and I have built an intermediate-level undergraduate lab experience in which students reinforce physics learning objectives and learn statistical data analysis skills while "discovering" a particle. A short form …

Creation And Development Of A Next Generation Simulation Model For Spacecraft Charging, Brian P. Beecken

Day of Scholarship

Spacecraft, particularly satellites, endure the bombardment of high-energy electrons. These electrons charge up the insulators on the spacecraft. Eventually, the charge commonaly can exceed 100,000 volts. The result is an electrostatic discharge which will potentially cripple the spacecraft. A computer simulation model has been developed that will predict if and when the discharge will occur.

On Naval Theory, Milan Vego

Naval War College Review

Too many naval officers mistrust, neglect, or even ignore the importance of naval theory, instead placing too much reliance on advanced technologies. Yet without full understanding of naval theory, it is very difficult to have the broad outlook necessary to develop naval doctrine, train one’s naval forces, and employ those forces successfully in a war.

Modeling And Estimation Of A Continuous Flexible Structure Using The Theory Of Functional Connections, Riccardo Bevilacqua

Math Department Colloquium Series

This talk presents a novel method for modeling and estimating the dynamics of a continuous structure based on a limited number of noisy measurements. The goal is reached using a Kalman filter in synergy with the recently developed mathematical framework known as the Theory of Functional Connections (TFC). The TFC allows to derive a functional expression capable of representing the entire space of the functions that satisfy a given set of linear and, in some cases, nonlinear constraints. The proposed approach exploits the possibilities offered by the TFC to derive an approximated dynamical model for the flexible system using the …
