Consumer Willingness-To-Pay for a Resilient Electrical Grid
The research objective is to estimate consumer willingness to pay (WTP) for electricity grid fortification. Data are from a representative survey of Oklahoma citizens. Extreme weather events, aging utility infrastructure, increased demand for affordable energy, and terrorism threaten the safety and security of the way most citizens access electricity. This study is a first look at public willingness to support energy grid security measures in the United States Southern Great Plains. Findings suggest that consumers would pay an additional 14 initiated by local electricity providers. The findings provide policymakers and energy providers with information on consumer willingness to support efforts to modernize the current grid
Behaviors and motivations for weight loss in children and adolescents: Weight Loss Behaviors and Motivations in Children
Examine the association between weight loss behaviors and motivations for weight loss in children and adolescents and the association of weight status with these behaviors and motivations in a nationally representative sample
Probing the Space of Toric Quiver Theories
We demonstrate a practical and efficient method for generating toric Calabi-Yau quiver theories, applicable to both D3 and M2 brane world-volume physics. A new analytic method is presented at low order parametres and an algorithm for the general case is developed which has polynomial complexity in the number of edges in the quiver. Using this algorithm, carefully implemented, we classify the quiver diagram and assign possible superpotentials for various small values of the number of edges and nodes. We examine some preliminary statistics on this space of toric quiver theories

Dynamic Versus Static Oxidation of Nb/Al-AlO/Nb Trilayer
High quality Nb-based superconductor-insulator-superconductor (SIS) junctions
with Al oxide (AlO) tunnel barriers grown from Al overlayers are widely
reported in the literature. However, the thin barriers required for high
critical current density (J) junctions exhibit defects that result in
significant subgap leakage current that is detrimental for many applications.
High quality, high-J junctions can be realized with AlN barriers, but
control of J is more difficult than with AlO. It is therefore of
interest to study the growth of thin AlO barriers with the ultimate goal of
achieving high quality, high-J AlO junctions. In this work, 100\%\
O and 2\%\ O in Ar gas mixtures are used both statically and
dynamically to grow AlO tunnel barriers over a large range of oxygen
exposures. In situ ellipsometry is used for the first time to extensively
measure AlO tunnel barrier growth in real time, revealing a number of
unexpected patterns. Finally, a set of test junction wafers was fabricated that
exhibited the well-known dependence of J on oxygen exposure (E) in order to
further validate the experimental setup
Phases of planar 5-dimensional supersymmetric Chern-Simons theory
In this paper we investigate the large- behavior of 5-dimensional
super Yang-Mills with a level Chern-Simons term and an
adjoint hypermultiplet. As in three-dimensional Chern-Simons theories, one must
choose an integration contour to completely define the theory. Using
localization, we reduce the path integral to a matrix model with a cubic action
and compute its free energy in various scenarios. In the limit of infinite
Yang-Mills coupling and for particular choices of the contours, we find that
the free-energy scales as for gauge groups with large values
of the Chern-Simons 't\,Hooft coupling, . If we also
set the hypermultiplet mass to zero, then this limit is a superconformal fixed
point and the behavior parallels other fixed points which have known
supergravity duals. We also demonstrate that gauge groups cannot have
this scaling for their free-energy. At finite Yang-Mills coupling we
establish the existence of a third order phase transition where the theory
crosses over from the Yang-Mills phase to the Chern-Simons phase. The phase
transition exists for any value of , although the details differ
between small and large values of . For pure Chern-Simons
theories we present evidence for a chain of phase transitions as
is increased.
We also find the expectation values for supersymmetric circular Wilson loops
in these various scenarios and show that the Chern-Simons term leads to
different physical properties for fundamental and anti-fundamental Wilson
loops. Different choices of the integration contours also lead to different
properties for the loops.Comment: 40 pages, 17 figures, Minor corrections, Published versio
