Analysis Of Methods For Assimilating Fire Perimeters Into A Coupled Fire-Atmosphere Model, Adam K. Kochanski, Kathleen Clough, Angel Farguell, Derek V. Mallia, Jan Mandel, Kyle Hilburn

Faculty Research, Scholarly, and Creative Activity

Correctly initializing the fire within coupled fire-atmosphere models is critical for producing accurate forecasts of meteorology near the fire, as well as the fire growth, and plume evolution. Improperly initializing the fire in a coupled fire-atmosphere model can introduce forecast errors that can impact wind circulations surrounding the fire and updrafts along the fire front. A well-constructed fire initialization process must be integrated within coupled fire-atmosphere models to ensure that the atmospheric component of the model does not become numerically unstable due to excessive heat fluxes released during the ignition, and that realistic fire-induced atmospheric circulations are established at the …

Faculty Research, Scholarly, and Creative Activity

Reaction of nickel and zinc triflates with the tridentate leucoverdazyl 1-isopropyl-3,5-di (2′-pyridyl)-6-oxo-2H-tetrazine (dipyvdH) and triethylamine resulted in the neutral coordination compounds M(dipyvd)2 (M = Ni,Zn). In acetonitrile, both compounds undergo two one electron oxidation processes, Zn (dipyvd)2 at −0.28 V and −0.12 V and Ni(dipyvd)2 at −0.32 V and −0.15 V vs ferrocene/ferricenium. Oxidations are ligand based resulting in an intermediate mixed valence species and a cationic bis(verdazyl) compound respectively. Oxidation of the ligand changes a localized, antiaromatic, non-planar 8π electron anion to a planar, delocalized 7π electron radical. The change in ligand structure results in an increase in the …

The antecedents of these factors are also studied, including perceived usefulness, ease of use, and effectiveness for cognitive factors; positive and negative feelings for affective factors; perceived number of users, number of peers, and social images for social factors. An online survey was conducted among 297 non-wearable-users in the U.S. to collect data. Structural equation modeling was used to …

Controlling Neocortical Epileptic Seizures Using Forced Temporal Spike-Time Stimulation: An In Silico Computational Study, Joseph Schmalz, Rachel V. Quinarez, Mayuresh V. Kothare, Gautam Kumar

Faculty Research, Scholarly, and Creative Activity

Epileptic seizure is typically characterized by highly synchronized episodes of neural activity. Existing stimulation therapies focus purely on suppressing the pathologically synchronized neuronal firing patterns during the ictal (seizure) period. While these strategies are effective in suppressing seizures when they occur, they fail to prevent the re-emergence of seizures once the stimulation is turned off. Previously, we developed a novel neurostimulation motif, which we refer to as “Forced Temporal Spike-Time Stimulation” (FTSTS) that has shown remarkable promise in long-lasting desynchronization of excessively synchronized neuronal firing patterns by harnessing synaptic plasticity. In this paper, we build upon this prior work by …

Very Short-Term Solar Power Forecasting Using A Frequency Incorporated Deep Learning Model, Hossein Panamtash, Shahrzad Mahdavi, Qun Zhou Sun, Guo Jun Qi, Hongrui Liu, Aleksandar Dimitrovski

Faculty Research, Scholarly, and Creative Activity

This paper aims to forecast solar power in very short horizons to assist in real-time distribution system operations. Popular machine learning methods for time series forecasting are studied, including recurrent neural networks with Long Short-Term Memory (LSTM). Although LSTM networks perform well in different applications by accounting for long-term dependencies, they do not consider the frequency domain patterns, especially the low frequencies in the solar power data compared to the sampling frequency. The State Frequency Memory (SFM) model in this paper extends LSTM and adds multi-frequency components into memory states to reveal a variety of frequency patterns from the data …

Distributed Cooperative Kalman Filter Constrained By Advection–Diffusion Equation For Mobile Sensor Networks, Ziqiao Zhang, Scott T. Mayberry, Wencen Wu, Fumin Zhang

Faculty Research, Scholarly, and Creative Activity

In this paper, a distributed cooperative filtering strategy for state estimation has been developed for mobile sensor networks in a spatial–temporal varying field modeled by the advection–diffusion equation. Sensors are organized into distributed cells that resemble a mesh grid covering a spatial area, and estimation of the field value and gradient information at each cell center is obtained by running a constrained cooperative Kalman filter while incorporating the sensor measurements and information from neighboring cells. Within each cell, the finite volume method is applied to discretize and approximate the advection–diffusion equation. These approximations build the weakly coupled relationships between neighboring …

New Diagonal Graph Ramsey Numbers Of Unicyclic Graphs, Richard M. Low, Ardak Kapbasov

Faculty Research, Scholarly, and Creative Activity

Grossman conjectured that R(G, G) = 2 · |V (G)| − 1, for all simple connected unicyclic graphs G of odd girth and |V (G)| ≥ 4. In this note, we prove his conjecture for various classes of G containing a triangle. In addition, new diagonal graph Ramsey numbers are calculated for some classes of simple connected unicyclic graphs of even girth.

In this study, observations of live fuel moisture content (LFMC) for predominantly sampled fuels in six distinct regions of California were examined from 2000 to 2021. To gather the necessary data, an open-access database called the Fuel Moisture Repository (FMR), was developed. By harnessing the extensive data aggregation and query capabilities of the FMR, which draws upon the National Fuel Moisture Database, valuable insights into the live fuel moisture seasonality were obtained. Specifically, our analysis revealed a distinct downtrend in LFMC across all regions, with the exception of the two Northernmost regions. The uptrends of LFMC seen in those regions …

Breaking Barriers By Preserving The Future: Fergus Falls Kirkbride, Deanna Hurley

Architecture Theses

The thought came to me over the Summer when I was visiting my hometown. There is a historical building called the Regional Treatment Center (RTC), and over the years, I have seen many attempts to repurpose it, but all have failed. We have visitors come from across the country and even other continents to see the RTC, and the city is losing out on potential profit for the community by not utilizing the RTC. Now, the city wants to tear the whole structure down (except the main tower), costing over 9 million dollars. Along with the great cost, loss of …

Inclusivity In Public Space: Architecture And The Disabled Body, Grace A. Dietz

Architecture Theses

People with disabilities are living in a world that simply was not built for them and it creates a lot of unnecessary struggle and bias because of that. Public spaces are especially discriminatory towards the disabled body, and yet the public world as it exists today is also more and more discriminatory towards every single one of our bodies because of reductive design strategies that place more emphasis on evolving technology such as cars over our bodily experience of design and space. The only way we can interact with the world is through our bodies. Our bodies move us through …

Retrofitting Architectural Environments In Response To An Evolving Workplace, Lexi Cheyenne Jordheim

Applying Single Cell Multi-Omic Analyses To Understand Treatment Resistance In Pediatric High Grade Glioma, Rebecca L Murdaugh, Jamie N Anastas

Faculty, Staff and Students Publications

Despite improvements in cancer patient outcomes seen in the past decade, tumor resistance to therapy remains a major impediment to achieving durable clinical responses. Intratumoral heterogeneity related to genetic, epigenetic, transcriptomic, proteomic, and metabolic differences between individual cancer cells has emerged as a driver of therapeutic resistance. This cell to cell heterogeneity can be assessed using single cell profiling technologies that enable the identification of tumor cell clones that exhibit similar defining features like specific mutations or patterns of DNA methylation. Single cell profiling of tumors before and after treatment can generate new insights into the cancer cell characteristics that …

Introduction: Multiple myeloma (MM) is an incurable cancer of malignant plasma cells that engraft in the bone marrow (BM). It is more than likely that the poorly investigated physical parameters of hypoxia and pH in the tumor microenvironment (TME) is critical for MM survival. Here, we explore the effects of a hypoxic environment on pH regulation and its role in MM survival.

Methods: We used in vitro models of MM, in which the culturing medium was modified to specific pH and pO2 levels and then measured the effects on cell survival that was correlated with changes in intracellular (pHi) and …

Rewiring Of Mitochondrial Metabolism In Therapy-Resistant Cancers: Permanent And Plastic Adaptations, Katherine E Pendleton, Karen Wang, Gloria V Echeverria

Faculty, Staff and Students Publications

Deregulation of tumor cell metabolism is widely recognized as a "hallmark of cancer." Many of the selective pressures encountered by tumor cells, such as exposure to anticancer therapies, navigation of the metastatic cascade, and communication with the tumor microenvironment, can elicit further rewiring of tumor cell metabolism. Furthermore, phenotypic plasticity has been recently appreciated as an emerging "hallmark of cancer." Mitochondria are dynamic organelles and central hubs of metabolism whose roles in cancers have been a major focus of numerous studies. Importantly, therapeutic approaches targeting mitochondria are being developed. Interestingly, both plastic (i.e., reversible) and permanent (i.e., stable) metabolic adaptations …
