#### The dynamics of enzymatic switch cascades

(Massachusetts Institute of Technology, 2004)

We examine the dynamics of the mitogen-activated protein kinase (MAPK) multi-step enzymatic switching cascade, a highly conserved architecture utilised in cellular signal transduction. In treating the equations of motion, ...

#### Gas electron multipliers in a time projection chamber

(Massachusetts Institute of Technology, 2003)

#### Intersecting brane landscape

(Massachusetts Institute of Technology, 2009)

This thesis studies intersecting brane models, which are a class of quasi-realistic compactifications of string theory. Techniques are developed for exploring the complete space of intersecting brane models on an orientifold. ...

#### The interior Casimir problem

(Massachusetts Institute of Technology, 2009)

We study the electromagnetic Casimir interaction of a metallic compact object with a compact and bounded metallic surface in which it is contained. We express the interaction energy in terms of the objects' scattering ...

#### Exoplanetary system WASP-3 : measurement of the projected spin-orbit angle and evidence for stellar activity

(Massachusetts Institute of Technology, 2009)

In this thesis, I present new spectroscopic and photometric observations of WASP-3, a transiting extrasolar planetary system. From spectra obtained during two transits, I use the Rossiter-McLaughlin effect in a simplified ...

#### Progress towards strong coupling between collisionally blockaded atoms and an optical cavity

(Massachusetts Institute of Technology, 2009)

In this thesis, I present the motivation and design for an experiment in which to probe the interactions between an atom and a single photon light field. I discuss the relevant technical considerations and many of the ...

#### Search for rare events in [the square root of sigma nu nu] = 200 GeV Au+Au PHOBOS data

(Massachusetts Institute of Technology, 2009)

In this analysis, we set an upper bound on the rate of rare events: events whose dN/dn distribution deviates more than statistically from the ensemble average dN/dn distribution for s [the square root of sigma nu nu] = 200 ...

#### Generation of fiber-coupled, nondegenerate, polarization-entangled photons for quantum communication

(Massachusetts Institute of Technology, 2009)

The production of polarization-entangled photon pairs from spontaneous parametric downconversion (SPDC) enables many applications of quantum information processing. In this thesis, we use type-0 phase-matched downconversion ...

#### Something to do with Schrödinger spacetimes

(Massachusetts Institute of Technology, 2009)

We present a brief review of the AdS/CFT correspondence and the progress made toward building a realistic gravity/gauge theory duality for a non-relativistic conformal field theory. In particular, we highlight many of the ...

#### Photometry and transit-timing analysis for eleven transiting exoplanets

(Massachusetts Institute of Technology, 2009)

This thesis presents time-series photometry of transits of 11 different extrasolar planets. Observations were conducted with the Fred L. Whipple Observatory 1.2m telescope and the Wise Observatory im telescope, in standard ...
