LGBTQ+ Health-a Novel Course for Undergraduate Students.
The concept of providing focused, competency-based LGBTQ+ health education outside the setting of health professional programs, specifically for undergraduates, is quite uncharted. However, the issue at the core of our rationale is one shared by those with and without clinical exposure: how to best support the development of cultural competence in providers who are or will be caring for LGBTQ+ patients. Traditional health professional education programs have enacted a number of curricular initiatives in this regard, designed for advanced learners. By focusing specifically on the undifferentiated learner, we offer a new perspective on the timing of LGBTQ+ health-related education. Our course is not intended to supplant the critical learning and application that must occur in the clinic or hospital room. Rather, we present a framework for cultivating understanding of the healthcare issues faced by the LGBTQ+ community that may help a learner to acquire and apply skills subsequently with greater cultural competence
Genuinely nonabelian partial difference sets
Strongly regular graphs (SRGs) provide a fertile area of exploration in
algebraic combinatorics, integrating techniques in graph theory, linear
algebra, group theory, finite fields, finite geometry, and number theory. Of
particular interest are those SRGs with a large automorphism group. If an
automorphism group acts regularly (sharply transitively) on the vertices of the
graph, then we may identify the graph with a subset of the group, a partial
difference set (PDS), which allows us to apply techniques from group theory to
examine the graph. Much of the work over the past four decades has concentrated
on abelian PDSs using the powerful techniques of character theory. However,
little work has been done on nonabelian PDSs. In this paper we point out the
existence of \textit{genuinely nonabelian} PDSs, i.e., PDSs for parameter sets
where a nonabelian group is the only possible regular automorphism group. We
include methods for demonstrating that abelian PDSs are not possible for a
particular set of parameters or for a particular SRG. Four infinite families of
genuinely nonabelian PDSs are described, two of which -- one arising from
triangular graphs and one arising from Krein covers of complete graphs
constructed by Godsil \cite{Godsil_1992} -- are new. We also include a new
nonabelian PDS found by computer search and present some possible future
directions of research.Comment: 24 page
Nonabelian partial difference sets constructed using abelian techniques
A -partial difference set (PDS) is a subset of a
group such that , , and every nonidentity element of
can be written in either or different ways as a product
, depending on whether or not is in . Assuming the identity is
not in and is inverse-closed, the corresponding Cayley graph will be strongly regular. Partial difference sets have been the
subject of significant study, especially in abelian groups, but relatively
little is known about PDSs in nonabelian groups. While many techniques useful
for abelian groups fail to translate to a nonabelian setting, the purpose of
this paper is to show that examples and constructions using abelian groups can
be modified to generate several examples in nonabelian groups. In particular,
in this paper we use such techniques to construct the first known examples of
PDSs in nonabelian groups of order , where is a power of an odd
prime and . The groups constructed can have exponent as small as
or as large as in a group of order . Furthermore, we
construct what we believe are the first known Paley-type PDSs in nonabelian
groups and what we believe are the first examples of Paley-Hadamard difference
sets in nonabelian groups, and, using analogues of product theorems for abelian
groups, we obtain several examples of each. We conclude the paper with several
possible future research directions.Comment: 26 page
The Economic Impacts and Risks Associated with Electric Power Generation in Appalachia
This report provides a detailed examination of the economic impacts of changes in electric power generation in Appalachia between 2005 and 2015. It finds that while coal represented around 74 percent of total electric generation in Appalachia in 2005, that percentage dropped to 53 percent in 2015. However, despite this decline, Appalachia remains more dependent on coal for electricity generation when compared with the rest of the country. This report also offers a risk factor analysis for coal-fired generation retirements and repowerings, and notes that coal prices have little influence on coal-fired power plant retirement decisions
Measuring Thermal Profiles in High Explosives using Neural Networks
We present a new method for calculating the temperature profile in high
explosive (HE) material using a Convolutional Neural Network (CNN). To
train/test the CNN, we have developed a hybrid experiment/simulation method for
collecting acoustic and temperature data. We experimentally heat cylindrical
containers of HE material until detonation/deflagration, where we continuously
measure the acoustic bursts through the HE using multiple acoustic transducers
lined around the exterior container circumference. However, measuring the
temperature profile in the HE in experiment would require inserting a high
number of thermal probes, which would disrupt the heating process. Thus, we use
two thermal probes, one at the HE center and one at the wall. We then use
finite element simulation of the heating process to calculate the temperature
distribution, and correct the simulated temperatures based on the experimental
center and wall temperatures. We calculate temperature errors on the order of
15{\deg}C, which is approximately 12% of the range of temperatures in the
experiment. We also investigate how the algorithm accuracy is affected by the
number of acoustic receivers used to collect each measurement and the
resolution of the temperature prediction. This work provides a means of
assessing the safety status of HE material, which cannot be achieved using
existing temperature measurement methods. Additionally, it has implications for
range of other applications where internal temperature profile measurements
would provide critical information. These applications include detecting
chemical reactions, observing thermodynamic processes like combustion,
monitoring metal or plastic casting, determining the energy density in thermal
storage capsules, and identifying abnormal battery operation
