Structure Of Number Theoretic Graphs, Lee Trent

Mathematical Sciences Technical Reports (MSTR)

The tools of graph theory can be used to investigate the structure
imposed on the integers by various relations. Here we investigate two
kinds of graphs. The first, a square product graph, takes for its vertices
the integers 1 through n, and draws edges between numbers whose product
is a square. The second, a square product graph, has the same vertex set,
and draws edges between numbers whose sum is a square.
We investigate the structure of these graphs. For square product
graphs, we provide a rather complete characterization of their structure as
a union of disjoint complete graphs. For …

Amphiphilic Cyclic Cell-Penetrating Peptides Containing Tryptophan And Arginine As Anticancer Agents And Drug Delivery System, Khalid Zoghebi

Pharmaceutical Sciences (PhD) Dissertations

Amphiphilic cyclic cell-penetrating peptides composed of an increasing number of alternative tryptophan (W) and arginine (R) were synthesized and evaluated as a molecular transporter and for their ability to deliver doxorubicin (Dox) and large molecular weight molecules, such as siRNA and proteins. We prepared a cyclic peptide containing alternative tryptophan (W) and arginine (R) residues and a lysine containing a free side chain amino group. Cyclic peptide [(WR)8WK βA] was conjugated through the free side chain amino group of β-alanine with Dox via a glutarate linker to afford [(WR)8WK]bA-Dox conjugate. The conjugate inhibited the cell viability of ovarian adenocarcinoma (SK-OV-3) …

Repeated Targets Of Natural Selection During Ecological Transitions Of Fish Across Salinity Boundaries, Jonathan P. Velotta, Stephen D. Mccormick, Andrew Whitehead, Catherine S. Durso, Eric T. Schultz

EEB Articles

Ecological transitions across salinity boundaries have led to some of the most important diversification events in the animal kingdom, especially among fishes. Adaptations accompanying such transitions include changes in morphology, diet, whole-organism performance, and osmoregulatory function, which may be particularly prominent since divergent salinity regimes make opposing demands on systems that maintain ion and water balance. Research in the last decade has focused on the genetic targets underlying such adaptations, most notably by comparing populations of species that are distributed across salinity boundaries. Here, we synthesize research on the targets of natural selection using whole-genome approaches, with a particular emphasis …

Halodash: The Deep And Shallow History Of Aquatic Life's Passages Between Marine And Freshwater Habitats, Eric T. Schultz, Lisa Park Boush

EEB Articles

This series of papers highlights research into how biological exchanges between salty and freshwater habitats have transformed the biosphere. Life in the ocean and in freshwaters have long been intertwined; multiple major branches of the tree of life originated in the oceans and then adapted to and diversified in freshwaters. Similar exchanges continue to this day, including some species that continually migrate between marine and fresh waters. The series addresses key themes of transitions, transformations, and current threats with a series of questions: When did major colonizations of fresh waters happen? What physiographic changes facilitated transitions? What organismal characteristics facilitate …

Schultz, Ary Serpa Neto

Anesthesiology Articles

Background: While an association of the intraoperative driving pressure with postoperative pulmonary complications has been described before, it is uncertain whether the intraoperative mechanical power is associated with postoperative pulmonary complications.

Methods: Posthoc analysis of two international, multicentre randomised clinical trials (ISRCTN70332574 and NCT02148692) conducted between 2011-2013 and 2014-2018, in patients undergoing open abdominal surgery comparing the effect of two different positive end-expiratory pressure (PEEP) levels on postoperative pulmonary complications. Time-weighted average dynamic driving pressure and mechanical power were calculated for individual patients. A multivariable logistic regression model adjusted for confounders was used to assess the independent associations of driving …

Response: In And Out Of The Game, As Usual, Steven E. Jones

English Faculty Publications

In this response article, I revisit the idea of paratext in video games. I start, however, with the example of a book by Tolstoy, and the textual studies work of McKenzie and McGann, in order to make the point that paratextuality has never been limited to Genette’s rigid definition, even in the case of print texts. Video games foreground what has always been the case: the dynamic, volatile, multidirectional nature of paratexts, which can take you into but also out of the enclosure of the main text (or “game itself”) in unexpected ways. Illustrations include Animal Crossing: New Horizons and …

Mapping And Making Meaning From Undergraduate Student Engagement In High-Impact Educational Practices, Bridget G. Trogden, Cazembe Kennedy, Nathan K. Biyani

Publications

Institutions of higher education often have multiple entry points for first-time and transfer college students to engage in high-impact educational practices (HIPs), well documented to advance student learning outcomes. Some students may seek out repeated opportunities while others engage very little or not at all in activities such as student-faculty research, study abroad, internships, first-year cohort programs, service-learning, and the like. When institutions maintain decentralized data and records on students’ participation, obtaining a true understanding of the "who, what, when, and where" of HIPs can be difficult. In this paper, we present an institutional strategy for longitudinal collection of data …

Diagnostic Featural Detection Or Filler Siphoning: A Red Box Study, Brynn Schuetter

Psychological Science Undergraduate Honors Theses

The current study is a replication and extension of previous research by Colloff and Wixted (2020). In their study, they created a novel identification procedure called the simultaneous showup. They found support for the diagnostic feature detection theory over the filler siphoning theory. The current study was interested in seeing if covert filler siphoning was still occurring in their novel procedure by asking participants how photos of fillers influenced their identification decision. Participants of the study viewed two crime videos and completed an identification task. If they were assigned to the simultaneous showup task, they were asked if and how …

Evaluation Of Selected Nuproxa Feed Additives For Protection Against Lameness And Improving The Wellbeing Of Broilers In A Lameness Challenge Model, Jaren Hernandez

Biological Sciences Undergraduate Honors Theses

A common concern in commercial industries profiting from broiler chickens is their inability to yield a completely healthy flock. Bacterial Chondronecrosis with Osteomyelitis poses a threat to these companies by impairing the birds' proximal and distal tibial and femoral heads. In 2000, roughly 17.3% of broiler chickens were affected by Bacterial Chondronecrosis with Osteomyelitis which caused a substantial economic loss in the industry (McNammee et al., 2000). BCO cannot be tied to a particular bacterial species; this experiment focuses on evaluating the efficacy of certain commercial feed additives while determining the bacterial species causing BCO in this set of the …

What Dictates Carbon Dioxide Emissions Worldwide?, Bhowmik Sujey Soori

2022 Spring Honors Capstone Projects - Archive

The factors that lead to carbon dioxide emissions worldwide have been a popular topic for the last 30 years; however, a relatively underexplored topic is the relationship between carbon dioxide emissions and economic growth. This paper attempts to identify what type of relationship exists between carbon dioxide emissions, economic development, and energy consumption. Multiple econometric models, including Ordinary Least Squares (OLS), fixed effects, and a random effects model, were estimated for a panel data set of roughly 100 countries from 1960 through 2016. The results of the models show that there is no correlation between real GDP per capita and …

An Analysis Of Suicide Coercion, Melissa Yvonne Horton

2022 Spring Honors Capstone Projects - Archive

This paper aims to define and understand the linguistic mechanisms behind incidents of suicide coercion. This is accomplished through case studies where there are sufficient records of the incidents that can give insight into the language the perpetrators used. Using well-established research on coercion in a general sense, this paper adjusts those ideas to specifically describe suicide coercion. To do this, quotes from each incident are broken down using speech-act theory to study the effect of the words on the listener, the perlocutionary acts of the perpetrator. This approach shows promising applications including legislating effective laws that target suicide coercion.

Degrees Of Pectoral Reduction On The Gymnophtalmidae Lizards, Thu M. Tran

2022 Spring Honors Capstone Projects - Archive

The Gymnophtalminae family comprises over 250 lizard species. Many of these microteiids present with reduced limbs that contribute to their snake-like appearance. Several predictions regarding limb reduction arise from genetic and environmental influence; however, there is limited literature supporting the impact of limb reduction on the pectoral girdle. Five Gymnophtalminae species were selected, and Dristhi software was used to perform CT segmentation to view their pectoral bones. Echinosaura horrida presents with the most developed pectoral structure, as this is a fully developed quadruped species. Whilst Calyptommatus leiolepis presents with the most reduction with a thinner structure and diverges from a …
