Modeling R8 Specification in the Drosophila Eye, from Genes to Tissue.
(2011)
Drosophila melanogaster, the fruit fly, has compound eyes consisting of around 750 facets called ommatidia, arranged in a regular hexagonal grid. Each facet is centered on a suite of 8 photoreceptor neurons (R1-R8), of ...
From structure to dynamics and back: The interplay between topology and activity in brain networks.
(2011)
The brain is an enormously complex network of neurons and supporting cells. The topological structure of these neuronal networks form the basis for learning, memory, cognition, and every other function. In return, those ...
Measurement of Z --> cc Transverse Momentum Distribution in Proton-proton Collisions at s = 7 TeV in the ATLAS Detector.
(2011)
The normalized distribution of Z->ee transverse momentum spectrum is measured in proton-proton collisions at center-of-mass energy of 7 TeV with the ATLAS detector. The results are based on a dataset corresponding to an ...
Optical Negative Index Metamaterials.
(2011)
Research of metamaterials focuses on unprecedented optical properties that may be obtained from composite media, and has attracted great attention since the seminal paper “Negative Refraction Makes a Perfect Lens”. The ...
Forward-Backward Asymmetry at High Mass in tt Production in pp Collisions at
(2011)
We present a new measurement of the inclusive forward-backward tbar{t} production asymmetry and its mass dependence. The measurements are performed with data corresponding to an integrated luminosity of L = 5.3 fb^{−1} of ...
Search for a Supersymmetry Signature with the ZY Plus Missing Transverse Energy Final State Using the D0 Detector.
(2011)
A search for a supersymmetry signature is conducted with events containing Zγ and large missing transverse energy at Fermilab’s Tevatron accelerator with ppbar collisions at center of mass energy 1.96 GeV. The data used ...
New Models of Dark Matter and Prospects for Measurements.
(2011)
This thesis covers a range of topics in model building and measurements with an
interest in solving the dark matter problem.
We begin with a model where the dark matter properties today are different than
they were at the ...
Dynamics of the Top Quark Beyond the Standard Model.
(2011)
The top quark, the heaviest fermion that has been observed, is an important particle in understanding the origin of electroweak symmetry breaking. This thesis is about various collider phenomenologies of the top quark and ...
Nonlinear Optical Enhancement from Aggregate and Ensemble Effects in Organic Systems.
(2011)
Organic optoelectronics provide several advantages over traditional Si based systems. These advantages are typically cost, ease of manufacturing, and environmental impact. One area of particular interest in the field of ...
