Almost Split Morphisms, Preprojective Algebras And Multiplication Maps Of Maximal Rank, Steven P. Diaz, Mark Kleiner

Mathematics - All Scholarship

With a grading previously introduced by the second-named author, the multiplication maps in the preprojective algebra satisfy a maximal rank property that is similar to the maximal rank property proven by Hochster and Laksov for the multiplication maps in the commutative polynomial ring. The result follows from a more general theorem about the maximal rank property of a minimal almost split morphism, which also yields a quadratic inequality for the dimensions of indecomposable modules involved.

Finite-Dimensional Algebras With Smallest Resolutions Of Simple Modules, Shashidhar Jagadeeshan, Mark Kleiner

Mathematics - All Scholarship

Let lamda be an associative ring with identity and with the Jacobson radical r, let mod lamda be the category of finitely generated left lamda-modules, and let lamda^op be the opposite ring of lamda. All modules are left unital modules, and if X is a module then pd X is the projective dimension of X. If lamda is left artinian and M in mod labmda, we denote by P(M) a projective cover of M.

An Evolutionary Multi-Objective Crowding Algorithm (Emoca): Benchmark Test Function Results, Ramesh Rajagopalan, Chilukuri K. Mohan, Kishan G. Mehrotra, Pramod K. Varshney

Electrical Engineering and Computer Science - All Scholarship

A new evolutionary multi-objective crowding algorithm (EMOCA) is evaluated using nine benchmark multiobjective optimization problems, and shown to produce non-dominated solutions with significant diversity, outperforming state-of-the-art multi-objective evolutionary algorithms viz., Non-dominated Sorting Genetic Algorithm – II (NSGA-II), Strength Pareto Evolutionary algorithm II (SPEA-II) and Pareto Archived Evolution Strategy (PAES) on most of the test problems. The key new approach in EMOCA is to use a diversity-emphasizing probabilistic approach in determining whether an offspring individual is considered in the replacement selection phase, along with the use of a non-domination ranking scheme. This approach appears to provide a useful compromise between the …

Suburban Adaptability: Urban Context, Joshua Seidner

Architecture Senior Theses

The urban environment historically fosters anonymity among urbanites denying individual expression, user flexibility, and family adaptability. The result is the draw to the suburban house model which inherently concedes ones' expression of individual identity. The urban landscape has historically formed with the core and periphery. Over the last sixty years the periphery has harbored the creation of suburbia. Traditionally, the urban landscape has, and continues to suppress individualism and flexibility to create uniformity and homogeneity[...] Arguably by default, suburbia creates a basic template which the end-user can customize. On the contrary, the urban environment does not foster the ability to …

Results On The Bias And Inconsistency Of Ordinary Least Squares For The Linear Probability Model, William C. Horrace, Ronald L. Oaxaca

Economics - All Scholarship

This note formalizes bias and inconsistency results for ordinary least squares (OLS) on the linear probability model and provides sufficient conditions for unbiasedness and consistency to hold. The conditions suggest that a "trimming estimator" may reduce OLS bias.

Inhibition Of Cellular Respiration By Doxorubicin, Zhimin Tao, Henry G. Withers, Harvey S. Penefsky, Jerry Goodisman, Abdul Kader Souid

Chemistry - All Scholarship

Doxorubicin executes apoptosis, a process known to produce leakage of cytochrome c and opening of the mitochondrial permeability transition pores. To define the loss of mitochondrial function by apoptosis, we monitored cellular respiration during continuous exposure to doxorubicin. A phosphorescence analyzer capable of stable measurements over at least 5 h was used to measure [O(2)]. In solutions containing glucose and cells, [O(2)] declined linearly with time, showing that the kinetics of oxygen consumption was zero order. Complete inhibition of oxygen consumption by cyanide indicated that oxidations occurred in the respiratory chain. A decline in the rate of respiration was evident …

Ego-1, A Putative Rna-Dependent Rna Polymerase, Is Required For Heterochromatin Assembly On Unpaired Dna During C. Elegans Meiosis, Eleanor M. Maine, Jessica Hauth, Thomas Ratliff, Valarie E. Vought, Xingyu She, William G. Kelly

Biology - All Scholarship

During meiosis in C. elegans, unpaired chromosomes and chromosomal regions accumulate high levels of histone H3 lysine 9 dimethylation (H3K9me2), a modification associated with facultative heterochromatin assembly and the resulting transcriptional silencing [1, 2]. Meiotic silencing of unpaired DNA may be a widely conserved genome defense mechanism [3–5]. The mechanisms of meiotic silencing remain unclear, although both transcriptional and posttranscriptional processes are implicated [3–5]. Cellular RNA-dependent RNA polymerases (RdRPs) function in development and RNA-mediated silencing in many species [3, 6, 7] and in heterochromatin assembly in S. pombe [3, 8]. There are four C. elegans RdRPs, including two with known …

Effects Of Disorder On Electron Transport In Arrays Of Quantum Dots, Alan Middleton, Shantenu Jha

Physics - All Scholarship

We investigate the zero-temperature transport of electrons in a model of quantum dot arrays with a disordered background potential. One effect of the disorder is that conduction through the array is possible only for voltages across the array that exceed a critical voltage $V_T$. We investigate the behavior of arrays in three voltage regimes: below, at and above the critical voltage. For voltages less than $V_T$, we find that the features of the invasion of charge onto the array depend on whether the dots have uniform or varying capacitances. We compute the first conduction path at voltages just above $V_T$ …

Notes On (Twisted) Lattice Supersymmetry, Simon Catterall

Physics - All Scholarship

We describe a new approach to the problem of putting supersymmetric theories on the lattice. The basic idea is to discretize a {\it twisted} formulation of the supersymmetric theory. For certain theories with extended supersymmetry these twisted formulations contain only integer spin fields. The twisting exposes a scalar nilpotent supercharge which generates an exact lattice symmetry. We gives examples from quantum mechanics, sigma models and Yang-Mills theories.

Dirac-Kähler Fermions And Exact Lattice Supersymmetry, Simon Catterall

Physics - All Scholarship

We discuss a new approach to putting supersymmetric theories on the lattice. The basic idea is to start from a {\it twisted} formulation of the underlying supersymmetric theory in which the fermions are represented as grassmann valued antisymmetric tensor fields. The original supersymmetry algebra is replaced by a twisted algebra which contains a scalar nilpotent supercharge Q. Furthermore the action of the theory can then be written as the Q-variation of some function. The case of {\cal N}=2 super Yang-Mills theory in two dimensions is discussed in some detail. We then present our proposal for discretizing this theory and derive …

Lattice Formulation Of {\Cal N}=4 Super Yang-Mills Theory, Simon Catterall

Physics - All Scholarship

We construct a lattice action for {\cal N}=4 super Yang-Mills theory in four dimensions which is local, gauge invariant, free of spectrum doubling and possesses a single exact supersymmetry. Our construction starts from the observation that the fermions of the continuum theory can be mapped into the component fields of a single real anticommuting Kahler-Dirac field. The original supersymmetry algebra then implies the existence of a nilpotent scalar supercharge Q and a corresponding set of bosonic superpartners. Using this field content we write down a Q-exact action and show that, with an appropriate change of variables, it reduces to a …

Grain Boundary Scars On Spherical Crystals, Mark Bowick, Thomas Einert, Peter Lipowsky, Jorg Schilling, Andreas R. Bausch

Physics - All Scholarship

We present an experimental system suitable for producing spherical crystals and for observing the distribution of lattice defects (disclinations and dislocations) on a significant fraction (50%) of the sphere. The introduction of fluorescently labeled particles enables us to determine the location and orientation of grain boundary scars. We find that the total number of scars and the number of excess dislocations per scar agree with theoretical predictions and that the geometrical centers of the scars are roughly positioned at the vertices of an icosahedron.

Ranking Inequality: Applications Of Multivariate Subset Selection, William C. Horrace, Joseph T. Marchand, Timothy M. Smeeding

Economics - All Scholarship

Inequality measures are often presented in the form of a rank ordering to highlight their relative magnitudes. However, a rank ordering may produce misleading inference, because the inequality measures themselves are statistical estimators with different standard errors, and because a rank ordering necessarily implies multiple comparisons across all measures. Within this setting, if differences between several inequality measures are simultaneously and statistically insignificant, the interpretation of the ranking is changed. This study uses a multivariate subset selection procedure to make simultaneous distinctions across inequality measures at a pre-specified confidence level. Three applications of this procedure are explored using country-level data …

Gentrification And Neighborhood Housing Cycles: Will America's Future Downtowns Be Rich?, Jan K. Brueckner, Stuart S. Rosenthal

Economics - All Scholarship

This paper identifies a new factor, the age of the housing stock, that affects where high- and low-income neighborhoods are located in U.S. cities. High-income households, driven by a high demand for housing services, will tend to locate in areas of the city where the housing stock is relatively young. Because cities develop and redevelop from the center outward over time, the location of these neighborhoods varies over the city's history. The model predicts a suburban location for the rich in an initial period, when young dwellings are found only in the suburbs, while predicting eventual gentrification once central redevelopment …

Ritual Legitimacy And Scriptural Authority, James W. Watts

Religion - All Scholarship

In this essay, James W. Watts explains the interdependence of texts and rituals with regard to ancient religions. Specifically, he outlines patterns of practice and developments in the ritual use of texts and the texual authorization of rituals in antiquity.

Watts also makes the case that beyond the interplay of texual authority and ritual legitimacy that most ancient cultures engaged in, Judaism was unique in elevating the Torah along with its other laws and stories to special "scriptural" status.

Retro Fitting In, Nartano Lim

Architecture Thesis Prep

Consumer culture has become a driving force within western society through the rise of expendable goods and the lower costs of manufacturing. The "good life" has now been made available to a much greater portion of society and as a result, possessions as signifiers of status have lost much of their exclusivity, but none of its effectiveness. How does one assert individuality by the products they choose?

A primary driving force of consumer culture is that goods have a designated obsolescence that is perhaps only surpassed by the users desire for something new sooner. This rapid rate of replacement is …
