#### An Application of Abstract Algebra to the Neural Code for Sound Localization in the Barn Owl

(2016-04-25)

Patterns of neural firing can be viewed as a binary code with each neuron as a bit,
with neurons which actively fire in response to a stimulus associated to a 1 and those
which do not fire associated to a 0. In previous ...

#### Relations between Derivations arising from Modular Forms

(2009-05-04)

Denote by L(a; b) the free complex Lie algebra on the two generators
a and b. For each integer m 0 there is a derivation 2m on L(a; b) that satis es
2m([a; b]) = 0 and 2m(a) = ad(a)2m(b). In this paper we study the ...

#### Simplicial Homology and De Rham's Theorem

(2009-05-04)

After giving the necessary background in simplicial homology and cohomology, we will
state Stokes's theorem and show that integration of di erential forms on a smooth,
triangulable manifold M provides us with a homomorphism ...

#### The Impact of Sector and Market Variance on Individual Equity Variance

(2009)

This paper investigates how changes in measures of sector and market variance affect
equity variance by examining forecasts of equity variance over 1, 5, and 22 day time
horizons. These forecasts were generated ...

#### Poisson Percolation on the Square Lattice

(2019-04-01)

In this paper, we examine two versions of inhomogeneous percolation on the 2D lattice,
which we will refer to as non-oriented and oriented percolation, and describe the
limiting shape of the component containing the origin ...

#### Do Medical Malpractice Reforms Affect Health Care Costs and Outcomes?

(2009-04-15)

The impact of medical malpractice reforms on the cost and quality of health care is
of
great interest to policy makers. This study examines national data on malpractice
reforms
implemented and health care provided to Medicare ...

#### A Model of Speculative Attacks and Devaluations in Korea and Indonesia

(2009)

Since the beginning of the Bretton Woods era, currency crises and speculative attacks
have affected the world economy. This paper presents a model, originally derived by
Blanco and Garber, that predicts one-period ahead ...

#### Morphisms with Only Mild Singular Fibers and Bertini Theorems over Finite Fields

(2016-05-04)

We compute the asymptotic density of non-singular hypersurfaces of bidegree (3, d)
in P^n×P^1 with only mild singular fibers over P^1 over a finite field F_q for n =
1, 2. When n = 1 and char F_q > 2, this asymptotic density ...

#### An Investigation into the Interdependency of the Volatility of Technology Stocks

(2009-04)

This paper examines the contemporaneous and dynamic relationships between the
volatilities of the technology stocks in the S&P 100 index. Factor analysis and
heterogeneous autoregressive regressions are used to ...

#### Valuing Localized Externalities: Hog Operations in North Carolina

(2009-04)

In the early 1990s, eastern North Carolina experienced a boom in industrial hog
production. Among the negative externalities generated by this activity, residential
property value losses due to operation proximity are some ...
