Ultra-Close Tidal Disruption Events with Prompt Hyperaccretion
(Georgia Institute of Technology, 2015-08-18)A bright flare from a galactic nucleus followed at late times by a t^-5/3 decay in luminosity is often considered to be the signature of a tidal disruption of a star by a massive black hole. The flare and afterglow are ... -
Ultra-Sensitive Broadband Receiver for Longwave Radio Reception
Longwaves, or low-frequency (LF) radio waves, are electromagnetic waves whose frequencies are less than 500 kHz. Due to their propagation at low frequencies, these waves experience low attenuation over great distances and ... -
Uncertainty Quantification of Machine Learned Density Functionals
Density Functional Theory(DFT) is one of the most popular and successful methods for quantum mechanical simulations of matter because of its relatively lower computational costs. While it is formally exact, approximations ... -
Uncovering the peatland root microbiome: Environmental factors shaping microbial community structure
This study examines the effects of simulated whole-ecosystem warming and elevated levels of carbon dioxide on the microbial communities within the root-soil microbiomes of vascular plants in peatlands. Root samples ... -
Uncovering the peatland root microbiome: Environmental factors shaping microbial community structure
This study examines the effects of simulated whole-ecosystem warming and elevated levels of carbon dioxide on the microbial communities within the root-soil microbiomes of vascular plants in peatlands. Root samples obtained ... -
Understanding Children's Gaze Behaviors
Identifying early signs of autism has been a challenging problem in the medical field. Many research studies aim to detect behavioral patterns of children with autism in the first three years of life. Early detection of ... -
Understanding Intrusive Questioning in Online Conversations
In online mental health platforms, ensuring that vulnerable users receive care without harm is of paramount importance. Our group created a representative, data-driven semantic taxonomy for harmful behaviors that occur on ... -
Understanding the Mechanism of Tricuspid Annuloplasty Suture Dehiscence
Functional tricuspid regurgitation is commonly repaired by ring annuloplasty. Suturing an annuloplasty ring into the tricuspid valve presents the potential for annular suture dehiscence (tear-out from the tissue) due to ... -
Uranyl phosphate minerals as long term sink in uranium bioremediation
(Georgia Institute of Technology, 2010-12-20)US Department of Energy nuclear fuel and weapon production has resulted in uranium contaminated soils and groundwater. As the magnitude of this environmental issue requires an in situ remediation strategy, bioreduction of ... -
Use of recycled linear low-density polyethylene carbon in Li-ion anodes
Lithium-ion batteries are commonly used in many small electronics around the world. Efforts to make components of Li-ion batteries more sustainable have ranged from use of a brown algae extract in Li-ion anodes to efforts ... -
Use of RNAi in Brachionus manjavacas to Inhibit Cold-Related Genes Implicated in Aging
(Georgia Institute of Technology, 2015-08-18)Aging can be affected by a number of factors, including temperature; for example, organisms tend to live significantly longer when exposed to colder temperatures. Previous studies suggest that this change in life expectancy ... -
Using an AR Simulation for Hospital Spill Cleanup Training in Highly-Infectious Disease Holding Units
This project explores the implementation of an augmented reality training simulation in a hospital cleanup environment. Specifically, the simulation teaches cleanup staff to correctly sanitize surfaces containing contaminated ... -
USING ASCORBIC ACID AND HIGH SALINITY TO EXTEND THE VIABILITY OF PROALES SIMILIS (ROTIFERA) DIAPAUSING EGGS
Rotifers are sensitive indicators of environmental conditions and serve as model organisms for assessing toxicity. It is understood that rotifer cysts (diapausing eggs) are convenient for toxicity assessment because they ... -
Using Defects in Anion Excess Rhenium Trioxide Type Fluorides to Control Thermal Expansion; Ytterbium Zirconium Fluoride as a Case Study
The average structure, thermal expansion, behavior on compression, high temperature stability, and moisture sensitivity of YbZrF₇, an anion-excess ReO₃-type material, was explored. Cubic YbZrF₇ (a = 4.10 Å) was synthesized ... -
Using First Order Inductive Learning as an Alternative to a Simulator in a Game Artificial Intelligence
(Georgia Institute of Technology, 2009-05-04)Currently many game artificial intelligences attempt to determine their next moves by using a simulator to predict the effect of actions in the world. However, writing such a simulator is time-consuming, and the simulator ... -
Using Guanine Rich Aptamer Strands to Increase Cellular Internalization of DNA Nanostructures
DNA, while best known for its coding abilities, can also be used as a structural material to form nanostructures. DNA nanostructures can be designed with very specific chemistry and structure size and shape, and have the ... -
Using Language Models in Causal Story Generation
Story generation remains a challenge because it is still difficult to automatically generate logically coherent yet natural stories. In this thesis, we propose an approach to this problem by combining our previous pipeline ... -
Using Polymorphic Microsatellites to Determine the Population Genetics of Vespula maculifrons
Social insects have an interesting genetic history and are studied in order to discern how their social behaviors affects their genetic makeup. The eastern yellowjacket Vespula maculifrons is one such species whose altruistic ... -
Using TreeLSTMs to Solve Combinatorial Optimization Papers
We study the problem of building and traversing a search tree for combinatorial optimization problems, which are generally exponential in time complexity and often characterize NP-Hard problems. A typical approach for such ... -
Utilization of Cytochrome b562 as a Localized Labile Heme Chelator
Heme is an essential, but toxic cofactor required for virtually all aerobic life. As a consequence, cells are challenged to safely traffic heme to hemoproteins that reside in every subcellular compartment. However, the ...
