Understanding how biodiversity responds to urbanization is challenging, due in part to the single-city focus of most urban ecological research. Here, we delineate continent-scale patterns in urban species assemblages by leveraging data from a multi-city camera trap survey and quantify how differences in greenspace availability and average housing density among 10 North American cities relate to the distribution of eight widespread North American mammals. To do so, we deployed camera traps at 569 sites across these ten cities between 18 June and 14 August. Most data came from 2017, though some cities contributed 2016 or 2018 data if it was …


Analytic Gradients For State-Averaged Multiconfiguration Pair-Density Functional Theory, Thais R. Scott, Matthew R. Hermes, Andrew M. Sand, Meagan S. Oakley, Donald G. Truhlar, Laura Gagliardi Jul 2020

Analytic Gradients For State-Averaged Multiconfiguration Pair-Density Functional Theory, Thais R. Scott, Matthew R. Hermes, Andrew M. Sand, Meagan S. Oakley, Donald G. Truhlar, Laura Gagliardi

Scholarship and Professional Work - LAS

Analytic gradients are important for efficient calculations of stationary points on potential energy surfaces, for interpreting spectroscopic observations, and for efficient direct dynamics simulations. For excited electronic states, as are involved in UV–Vis spectroscopy and photochemistry, analytic gradients are readily available and often affordable for calculations using a state-averaged complete active space self-consistent-field (SA-CASSCF) wave function. However, in most cases, a post-SA-CASSCF step is necessary for quantitative accuracy, and such calculations are often too expensive if carried out by perturbation theory or configuration interaction. In this work, we present the analytic gradients for multiconfiguration pair-density functional theory based on SA-CASSCF …

Comparative Analysis Of The Human Serine Hydrolase Ovca2 To The Model Serine Hydrolase Homolog Fsh1 From S. Cerevisiae, Jessica S. Bun, Michael D. Slack, Daniel E. Schemenauer, R. Jeremy Johnson Mar 2020

Comparative Analysis Of The Human Serine Hydrolase Ovca2 To The Model Serine Hydrolase Homolog Fsh1 From S. Cerevisiae, Jessica S. Bun, Michael D. Slack, Daniel E. Schemenauer, R. Jeremy Johnson

Over 100 metabolic serine hydrolases are present in humans with confirmed functions in metabolism, immune response, and neurotransmission. Among potentially clinically relevant but uncharacterized human serine hydrolases is OVCA2, a serine hydrolase that has been linked with a variety of cancer-related processes. Herein, we developed a heterologous expression system for OVCA2 and determined the comprehensive substrate specificity of OVCA2 against two ester substrate libraries. Based on this analysis, OVCA2 was confirmed as a serine hydrolase with a strong preference for long-chain alkyl ester substrates (>10-carbons) and high selectivity against a variety of short, branched, and substituted esters. Substitutional analysis …


The Knapsack Subproblem Of The Algorithm To Compute The Erdos-Selfridge Function, Brianna Sorenson Jan 2020

The Knapsack Subproblem Of The Algorithm To Compute The Erdos-Selfridge Function, Brianna Sorenson

Undergraduate Honors Thesis Collection

This thesis summarizes the methodology of a new algorithm to compute the Erdos-Selfridge function which uses a wheel sieve, shows that a knapsack algorithm can be used to minimize the work needed to compute these values by selecting a subset of rings for use in the wheel, and compares the results of several different knapsack algorithms in this particular scenario.


Model-Based Cluster Analysis Of Indiana Social Security Beneficiary Data, Gwendolyn Spencer Jan 2020

Model-Based Cluster Analysis Of Indiana Social Security Beneficiary Data, Gwendolyn Spencer

Undergraduate Honors Thesis Collection

Annual reports of the U.S. Old-Age, Survivors, and Disability Insurance (OASDI) program, published by the Social Security Administration, detail the aggregate information about the program for each U.S. Postal ZIP code. This information includes the types of beneficiaries and monthly benefits received. These reports present the opportunity for contemporary analysis of the aggregate information about the OASDI program. To better capture the significance of the most-recent report for 2018, this project will use model-based cluster analysis, the unsupervised machine-learning process of grouping similar data points, to compare the 2017 and 2018 data. Due to the large amount of data, the …


The Characterization And Reactivity Of Tris(4-Methylpyrazolyl)Methane And Its Tungsten And Molybdenum Metal Complexes, Julia M. Pomeroy Jan 2020

The Characterization And Reactivity Of Tris(4-Methylpyrazolyl)Methane And Its Tungsten And Molybdenum Metal Complexes, Julia M. Pomeroy

Undergraduate Honors Thesis Collection

The scorpionate ligand tris(pyrazolyl)borate (Tp) has contributed to the understanding of coordination and organometallic chemistry and has proven to be useful in the synthesis of metalloprotein models. Studies focusing on the similar ligand, tris(pyrazolyl)methane (Tpm), have recently been made possible with improved synthetic techniques. Characterization of the Tpm ligand and its metal derivatives, [TpmW(CO)3L]+ and [TpmMo(CO)3L]+, unveiled unexpected activity in the 1H NMR chemical shift of the methane hydrogen after the coordination of a seventh ligand. The more electronegative the seventh ligand was, the more downfield the chemical shift appeared. Various analogs of Tpm have since been synthesized that substitute …
