Wormholes, Superfast Computations, And Selivanov's Theorem, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

While modern computers are fast, there are still many practical problems that require even faster computers. It turns out that on the fundamental level, one of the main factors limiting computation speed is the fact that, according to modern physics, the speed of all processes is limited by the speed of light. Good news is that while the corresponding limitation is very severe in Euclidean geometry, it can be more relaxed in (at least some) non-Euclidean spaces, and, according to modern physics, the physical space is not Euclidean. The differences from Euclidean character are especially large on micro-level, where quantum …

Ce-Qual-W2 Performance Assessment Modeling 1979 Grh Flume Study, Logan Negherbon

Civil and Environmental Engineering Master's Project Reports

In an early review of numerical reservoir hydrodynamic models, the US Army Corps of Engineers developed a physical model at the US Army Waterways Experiment Station to assess the performance of modeling cold water underflow with numerous 2-dimensional and 3-dimensional numerical hydrodynamic models. Within this effort, the precursor for CE-QUAL-W2, the Laterally Averaged Reservoir Model, was defined and applied with limited success in representing the vertical velocity profile and outflow temperatures series collected from the physical model in the General Reservoir Hydrodynamics flume. CE-QUAL-W2 has since been modified from this early form in numerous ways including incorporation of higher order …

Evaluating The Enzymatic Activity Of Transformed X. Cucurbitae, Emily Beger, Iris Lee, Sarah Hind

PRECS student projects

Introduction

• The United States’ pumpkin industry exceeds one billion dollars [1], with Illinois contributing to over 90% of processing pumpkin production.
• Pumpkin growers face a rising concern due to the increasing occurrence of Xanthomonas cucurbitae , the pathogen that causes bacterial spot disease in cucurbits, including pumpkins.
• X. cucurbitae infection leads to the appearance of small, sunken, beige spots on cucurbit fruits and leaves.
• Over time, the bacterium can compromise fruit integrity by breaking down the epidermis and cuticle. • Bacterial spot disease also creates opportunities for other bacteria and fungi to infiltrate the affected fruits, leading to fruit rot …

Synthesis And Characterization Of Terbium(Iii) Complexes: Can We Manipulate The Emission Signature?, Ryan Gagnon

[Archive] Belmont University Research Symposium (BURS)

Successful Lewis acid/base reactions of terbium(III) nitrate with 2,2’-bipyrdine (22’bpy), 1,10-phenanthroline (phen), and 2,6-pyridine dimethanol (pydm) have yielded the products: Tb(22’bpy)₂(NO₃)₃, Tb(phen)₂(NO₃)_3, and [Tb(pydm)₃](NO₃)₃, respectively. In accord with the well-known antenna-effect, the absorption spectrum of each complex is similar to the spectrum of the free ligand, while the emission spectrum of the complex is identical for the free terbium(III) ion. In contrast, the substitution of a ligand containing a third-row nonmetal strategically placed near the terbium may force interaction between the 3p nonmetal …

Crystal Structure Of Dihydrofolate Reductase From The Filarial Nematode W. Bancrofti In Complex With Nadph And Folate, Keith Lange, Kathleen M. Frey, Tyler Eck, Cheryl A. Janson, Ueli Gubler, Nina M. Goodey

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Lymphatic filariasis is a debilitating illness with an estimated 50 million cases as of 2018. The majority of cases are caused by the parasitic worm W. bancrofti and additional cases by the worms B. malayi and B. timori. Dihydrofolate reductase (DHFR) is an established target in the treatment of cancer, bacterial, and protozoal infections and may be a potential target for drugs targeting parasitic worm infections, including filariasis. Recent studies have shown that known antifolate compounds, including methotrexate, inhibit the activity of W. bancrofti DHFR (WbDHFR). However, the absence of structural information for filarial DHFRs has limited the study of …

The Effects Of Imposed Drought And Nutrient Availability On Soil Microbial Biomass And Enzyme Activity In A Long-Term Restored Grassland, Ashley A. Wojciechowski

2023 Midwest Ecology & Evolution Conference

Restoring agricultural lands back to grassland aims to reverse many negative impacts of agriculture on the ecosystem including nutrient export from soil and depletion of soil carbon. Planting prairie on agricultural soil promotes recovery of soil microbial biomass and their enzymes, which create demand for nitrogen by microbes to reduce the rate of nutrient cycling and loss. A complicating factor in the development of a restored grassland the influence of several anthropogenic global changes including increasing frequency of drought and nutrient enrichment. Drought has been found to negatively affect microbial biomass, soil enzyme activity and nutrient cycling. Nutrient (often N) …

The Effects Of False Springs And Late Freezing Events On Germination Success Of Prairie Plants, Sawyer J. Wittman

2023 Midwest Ecology & Evolution Conference

Prairie ecosystems are some of the most fragmented habitats across the Midwestern USA and are susceptible to the effects of climate change. False springs occur when temperatures rise unseasonably early, followed by low temperatures returning. A late freeze is when temperatures drop drastically in early spring, potentially damaging the plants that begin to grow. This research experimentally tests how winter climate change affects the germination rates of 24 different prairie plant species (12 in Poaceae, 4 Asteraceae, 4 in Fabaceae, and 4 in Lamiaceae), where half bloom in the spring and half bloom in the summer. Seeds are cold stratified …

Preliminary Report On Fossil Marine Vertebrates From The Upper Cretaceous Hartland Shale From Republic County, Kansas, Brianna E. Ortiz

2023 Midwest Ecology & Evolution Conference

The Hartland Shale of the Upper Cretaceous Greenhorn Limestone is a rock unit broadly distributed in north-central Kansas, that formed in the Western Interior Seaway, a Late Cretaceous epicontinental seaway in North America approximately 93 million years ago. The vertebrate fossil record of the Hartland Shale of Kansas is poorly known, where previous records were confined to a tooth of the extinct lamniform shark Cretoxyrhina mantelli and skeletal remains of a plesiosaur besides taxonomically uninformative bones and teeth of bony fishes. Here, we describe additional teeth of C. mantelli as well as the discovery of multiple teeth belonging to a …

Rapid Assesment Of Aquatic Insect Diversity And Abundance Used To Evaluate The Quality Of Stream Restoration, Kaleb Stephen Kindoll

2023 Midwest Ecology & Evolution Conference

Stream and wetland restoration activities seek to improve the function of aquatic ecosystems. Measurement of the diversity and abundance of aquatic insects are commonly used to evaluate the success of restoration efforts, but these measurements are often very time consuming. In this study, we attempt to construct an efficient method that can be used to rapidly assess the diversity and abundance of aquatic insects as a measure of the quality of stream restoration. We suspended uniform sized pieces of cardboard paper coated with adhesive to trap insects in three different environments: one restored and two unrestored streams with similar characteristics. …

Evaluating Habitat Suitability In Lake Superior And Michigan Streams For The Freshwater Diatom, Didymosphenia Geminata, Nuphar Rimer

2023 Midwest Ecology & Evolution Conference

Didymosphenia geminata (didymo or rock snot) is a benthic, freshwater diatom that is native to North America and Europe. Although it is native, it is displaying invasive qualities through seasonal stalk production. Stalks accumulate into large, unattractive mats that have the potential to alter benthic aquatic communities. The ecology of didymo is puzzling; it has been steadily expanding outside of its native range, and seasonal mat production can be unpredictable. Michigan is well known for outdoor recreation, attracting sportsmen from around the world to fish. Fishing is an integral part of Michigan’s tourism industry, but high foot traffic increases the …

Monitoring Personal Exposure To Air Quality Gradients While Biking On An Elevated Urban Trail, Gavin Salas

2023 Midwest Ecology & Evolution Conference

Air pollution is a major global health concern, specifically as it relates to the human exposome. The EPA criteria pollutants, including particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), and NOx can have severe impacts on respiratory and cardiovascular health, particularly in populations with chronic illnesses such as asthma, those facing economic hardships and individuals who frequently spend time outdoors, such as bicyclists and runners. To understand the impact of air pollution on human health, it is essential to assess personal exposure. This study aimed to investigate personal exposure to air pollution levels while biking along a former elevated …

Colorimetric Redox Reactions To Determine Base Composition In Unknown Monomeric Dna Samples, James T. Dials, Mara J. Stout, Elizabeth M. Thomas

2023 Celebration of Student Scholarship - Poster Presentations

Deoxyribonucleic acid (DNA) codes for proteins using a unique order of four major nitrogenous bases adenine, thymine, cytosine, and guanine. In several biological applications, such as the determination of DNA stability, production of biologic based drugs, and even taxonomic reorganization of species, it becomes necessary to understand the relative amounts of each nucleotide in a DNA sample, regardless of their sequence. However, most assays used to determine base composition use expensive equipment, harsh chemicals, and advanced computer software. In addition, the determination of base composition is an important educational tool in undergraduate laboratories, but these limitations are infeasible for many …

Everything Is A Matter Of Degree: The Main Idea Behind Fuzzy Logic Is Useful In Geosciences And In Authorship, Christian Servin, Aaron Velasco, Edgar Daniel Rodriguez Velasquez, Vladik Kreinovich

Departmental Technical Reports (CS)

This paper presents two applications of the general principle -- the everything is a matter of degree -- the principle that underlies fuzzy techniques. The first -- qualitative -- application helps explain the fact that while most earthquakes occur close to faults (borders between tectonic plates or terranes), earthquakes have also been observed in areas which are far away from the known faults. The second -- more quantitative -- application is to the problem of which of the collaborators should be listed as authors and which should be simply thanked in the paper. We argue that the best answer to …

Conflict Situations Are Inevitable When There Are Many Participants: A Proof Based On The Analysis Of Aumann-Shapley Value, Sofia Holguin, Vladik Kreinovich

Departmental Technical Reports (CS)

When collaboration of several people results in a business success, an important issue is how to fairly divide the gain between the participants. In principle, the solution to this problem is known since the 1950s: natural fairness requirements lead to the so-called Shapley value. However, the computation of Shapley value requires that we can estimate, for each subset of the set of all participants, how much gain they would have gained if they worked together without others. It is possible to perform such estimates when we have a small group of participants, but for a big company with thousands of …

Integrity First, Service Before Self, And Excellence: Core Values Of Us Air Force Naturally Follow From Decision Theory, Martine Ceberio, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

By analyzing data both from peace time and from war time, the US Air Force came with three principles that determine success: integrity, service before self, and excellent. We show that these three principles naturally follow from decision theory, a theory that describes how a rational person should make decisions.

People Prefer More Information About Uncertainty, But Perform Worse When Given This Information: An Explanation Of The Paradoxical Phenomenon, Jieqiong Zhao, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In a recent experiment, decision makers were asked whether they would prefer having more information about the corresponding situation. They confirmed this preference, and such information was provided to them. However, strangely, the decisions of those who received this information were worse than the decisions of the control group -- that did not get this information. In this paper, we provide an explanation for this paradoxical situation.

How People Make Decisions Based On Prior Experience: Formulas Of Instance-Based Learning Theory (Ilbt) Follow From Scale Invariance, Palvi Aggarwal, Martine Ceberio, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

To better understand human behavior, we need to understand how people make decisions, how people select one of possible actions. This selection is usually based on predicting consequences of different actions, and these predictions are, in their turn, based on the past experience. For example, consequences that occur more frequently in the past are viewed as more probable. However, this is not just about frequency: recent observations are usually given more weight that past ones. Researchers have discovered semi-empirical formulas that describe our predictions reasonably well; these formulas form the basis of the Instance-Based Learning Theory (ILBT). In this paper, …
