Is The Pamela Positron Excess Winos?, Scott Watson, Phill Grajek, Gordon L. Kane, Daniel J. Phalen, Aaron Pierce

Physics - All Scholarship

Recently the PAMELA satellite-based experiment reported an excess of galactic positrons that could be a signal of annihilating dark matter. The PAMELA data may admit an interpretation as a signal from a wino-like LSP of mass about 200 GeV, normalized to the local relic density, and annihilating mainly into W-bosons. This possibility requires the current conventional estimate for the energy loss rate of positrons be too large by roughly a factor of five. Data from anti-protons and gamma rays also provide tension with this interpretation, but there are significant astrophysical uncertainties associated with their propagation. It is not unreasonable to …

Lattice Super-Yang-Mills Using Domain Wall Fermions In The Chiral Limit, Simon Catterall, Joel Giedt, Richard Brower, George T. Fleming, Pavlos Vranas

Physics - All Scholarship

Lattice N=1 super-Yang-Mills theory formulated using Ginsparg-Wilson fermions provides a rigorous non-perturbative definition of the continuum theory that requires no fine-tuning as the lattice spacing is reduced to zero. Domain wall fermions are one explicit scheme for achieving this and using them we have performed large-scale Monte Carlo simulations of the theory for gauge group SU(2). We have measured the gaugino condensate, static potential, Creutz ratios and residual mass for several values of the domain wall separation L_s, four-dimensional lattice volume, and two values of the gauge coupling. With this data we are able to extrapolate the gaugino condensate to …

Public Long-Term Care Insurance And The Housing And Living Arrangements Of The Elderly: Evidence From Medicare Home Health Benefits, Gary V. Engelhardt, Nadia Greenhalgh-Stanley

Economics - All Scholarship

We provide empirical evidence on the extent to which long-term care insurance affects the housing and living arrangements of the elderly by examining plausibly exogenous changes in the supply of long-term care insurance through the Medicare program that occurred in the late 1990s. Prior to 1997, Medicare reimbursed home health care agencies on a retrospective-cost basis. Then, starting in October, 1997, as a result of the Balanced Budget Act of 1997 (BBA97), Medicare switched to a system of prospective payments for home health care, which induced state-by-calendar-year variation in the supply of this type of public long-term care insurance. We …

Dynamics Of Quasiconformal Fields, Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen

Mathematics - All Scholarship

A uniqueness theorem is established for autonomous systems of ODEs, x= f(x), where f is a Sobolev vector field with additional geometric structure, such as delta-monoticity or reduced quasiconformality. Specifically, through every non-critical point of f there passes a unique integral curve.

Molecular Hydrogen Formation On Low Temperature Surfaces In Temperature Programmed Desorption Experiments, Gianfranco Vidali, Ling Li, J. Roser, E. Congiu

Physics - All Scholarship

The study of the formation of molecular hydrogen on low temperature surfaces is of interest both because it allows to explore elementary steps in the heterogeneous catalysis of a simple molecule and because of the applications in astrochemistry. Here we report results of experiments of molecular hydrogen formation on amorphous silicate surfaces using temperature-programmed desorption (TPD). In these experiments beams of H and D atoms are irradiated on the surface of an amorphous silicate sample. The desorption rate of HD molecules is monitored using a mass spectrometer during a subsequent TPD run. The results are analyzed using rate equations and …

Phase Diagram Of Su(2) With 2 Flavors Of Dynamical Adjoint Quarks, Simon Catterall, Joel Giedt, Francesco Sannino, Joe Schneible

Physics - All Scholarship

We report on numerical simulations of SU(2) lattice gauge theory with two flavors of light dynamical quarks in the adjoint of the gauge group. The dynamics of this theory is thought to be very different from QCD -- the theory exhibiting conformal or near conformal behavior in the infrared. We make a high resolution survey of the phase diagram of this model in the plane of the bare coupling and quark mass on lattices of size 8^3 \times 16. Our simulations reveal a line of first order phase transitions extending from beta=0 to beta=beta_c \sim 2.0. For beta > beta_c the …

Exploration Of A Physical Picture For The Qcd Scalar Channel, Joseph Schechter, Amir H. Fariborz, Renata Jora

Physics - All Scholarship

A generalized linear sigma model is employed to study the quark structure of low lying scalar as well as pseudoscalar states. The model allows the possible mixing of quark anti-quark states with others made of two quarks and two antiquarks but no a priori assumption is made about the quark contents of the predicted physical states. Effects of SU(3) symmetry breaking are included. The lighter conventional pseudoscalars turn out to be primarily of two quark type whereas the lighter scalars have very large four quark admixtures.

Neutralino Dark Matter From Indirect Detection Revisited, Scott Watson, Phill Grajek, Gordon Kane, Daniel J. Phalen, Aaron Pierce

Physics - All Scholarship

We revisit indirect detection possibilities for neutralino dark matter, emphasizing the complementary roles of different approaches. While thermally produced dark matter often requires large astrophysical "boost factors" to observe antimatter signals, the physically motivated alternative of non-thermal dark matter can naturally provide interesting signals, for example from light wino or Higgsino dark matter. After a brief review of cosmic ray propagation, we discuss signals for positrons, antiprotons, synchrotron radiation and gamma rays from wino annihilation in the galactic halo, and examine their phenomenology. For pure wino dark matter relevant to the LHC, PAMELA and GLAST should report signals.

On The Colored Jones Polynomial, Sutured Floer Homology, And Knot Floer Homology, J. Elisenda Grigsby, Stephan Wehrli

Mathematics - All Scholarship

Let K in S³ be a knot, and let K denote the preimage of K inside its double branched cover, Sigma(S³, K). We prove, for each integer n > 1, the existence of a spectral sequence from Khovanov's categorification of the reduced n-colored Jones polynomial of K (mirror of K) and whose E^infinity term is the knot Floer homology of (Sigma(S³,K),K) (when n odd) and to (S³, K # K) (when n even). A corollary of our result is that Khovanov's categorification of the reduced n-colored Jones polynomial detects the unknot whenever n …

Interest On Bank Reserves And Optimal Sweeping, David D. Vanhoose, Donald H. Dutkowsky

Economics - All Scholarship

This paper utilizes a profit maximizing banking model to analyze sweeping behavior. Comparative statics results indicate that sweeping responds positively to increases in bank loan rates and reserve ratios and negatively to increases in the interest rate on reserves or to exogenous increases in bank deposits or equity. Sweeping generates greater responsiveness in lending to changes in loan rates or the interest rate on reserves and lower responsiveness to exogenous changes in reserve ratios or equity. Empirical analysis of an explicit condition that we derive relating sweeping to the interest rate on reserves suggests with an unchanged reserve requirement, the …

Contributions To Khovanov Homology, Stephan M. Wehrli

Mathematics - All Scholarship

Khovanov homology ist a new link invariant, discovered by M. Khovanov, and used by J. Rasmussen to give a combinatorial proof of the Milnor conjecture. In this thesis, we give examples of mutant links with different Khovanov homology. We prove that Khovanov's chain complex retracts to a subcomplex, whose generators are related to spanning trees of the Tait graph, and we exploit this result to investigate the structure of Khovanov homology for alternating knots. Further, we extend Rasmussen's invariant to links. Finally, we generalize Khovanov's categorifications of the colored Jones polynomial, and study conditions under which our categorifications are functorial …

Untitled, Darren Poon

Architecture Master Theses

"My objective is to explore the potential of generative design processes driven by user-derived parameters established through computational protocols, algorithms, and simulations resulting in a process embodying ecologies of feedback and performances. Inherent in the designed process is the establishment of feedback, through each cycle of simulation, evaluation, and modification of the geometry.

This thesis project demonstrates a version of these processes specifically examining the performance driven building typology of the massive server farm. Specifically, its implicit correlations with fluid dynamic simulation and its biases toward an optimization of heat dissipation and plan layout. This project is situated between a …

Construction For Art, Will Fellis

Architecture Thesis Prep

"When museums draw large crowds and display large collections, there is a lack of personal relationship and understanding of the art.

Small scale museum architecture, in the form of single galleries or pavilions housing only a few pieces by a specific artist or simply expressing the concepts of a certain artist's work, offers and opportunity to create a more intimate relationship between the artwork and the viewer.

The design of a pavilion according to an artist's philosophy will be manifested within the construction. Therefore the detailing of the pavilion will be the point at which the occupant engages the principles …

The Lobby: Volume One, Paul Miller

Architecture Thesis Prep

"There have been many projections of a utopian society where all should have access to humanity's total body of knowledge. With that knowledge, the people would be granted power: But in fact, not many have access to the kind of knowledge that produces power; and many who do don't know how to use it. Knowledge is only power if you control it.

In Washington D.C., a priviledged group of political consultants, the lobbyists, have slowly and steadily gained a tremendous amount of power through their control of information needed by private citizens, corporations, and elected officials. Always the middleman, the …

Sparsification And The Reconsideration Of Contemporary Rural Living, Eric Murphy

Architecture Thesis Prep

"This thesis asserts that architecture and agriculture must form a symbiotic relationship united by sustainability to redefine contemporary rural living. By challenging outdated traditions, idyllic visions, and preconceived notions of the rural paradigm, it is also possible to reprove a diminishing agrarian lifestyle. Rural architecture must become as productive as the ground it replaces, and as integrated as the crop to the soil. A new model needs to be established to facilitate these assertions and reconsider contemporary rural living."

Mil_Civ Immersive Surface, Elizabeth M. Quick

Architecture Thesis Prep

"The pervasive proliferation of complex tracking systems such as GPS and simulation gaming environments such as Full Spectrum Warrior are transforming the built environment into an immersive 1:1 map where all flows and transactions are measured, monitored, and tracked. The gap between map and real experience disappears resulting in an immersive map. The spatial implications of this real time 1:1 immersive map creates an opportunity for architecture itself to monitor, track, and measure flows and transactions. This tracking and simulation agenda plays out specifically in the design of a surface that integrates military training, military artifacts, and civilian recreation into …
