#### Analysis of the swimming-to-crawling transition of Caenorhabditis elegans in viscous fluid

(Massachusetts Institute of Technology, 2008)

The locomotory behavior of the nematode Caenorhabditis elegans is often characterized by two distinct gaits - swimming when in fluids and crawling when on surfaces. Swimming is characterized by about a twice greater ...

#### The Gamma Intensity Monitor at the Crystal-Barrel-Experiment

(Massachusetts Institute of Technology, 2008)

This thesis details the motivation, design, construction, and testing of the Gamma Intensity Monitor (GIM) for the Crystal-Barrel-Experiment at the Universität Bonn. The CB-ELSA collaboration studies the baryon excitation ...

#### Spin-squeezing of ⁸⁷Rb via optical measurement

(Massachusetts Institute of Technology, 2008)

This project aims to reduce measurement uncertainty in atomic clocks by squeezing the collective spin of atoms. Spin-squeezing reduces noise below the standard quantum limit where precision scales as 1/ [square root of] ...

#### Finite-difference time-domain analysis of horn antenna scattering

(Massachusetts Institute of Technology, 1998)

#### Tactic behaviors in bacterial dynamics

(Massachusetts Institute of Technology, 2005)

The locomotion of a wide class of motile bacteria can be mathematically described as a biased random walk in three-dimensional space. Fluid mechanics and probability theory are invoked to model the dynamics of bacteria ...

#### Solving the Dirac equation in a two-dimensional spacetime background with a kink

(Massachusetts Institute of Technology, 2005)

In the following paper, I study the Dirac equation in curved spacetime and solve this equation in two-dimensional spacetime backgrounds discovered by Jackiw et al[4], [5]. I will first discuss flat spacetime and introduce ...

#### The ground state and angular distributions of Ag18ÌŠ

(Massachusetts Institute of Technology, 1965)

#### Plasma oscillations in a laser.

(Massachusetts Institute of Technology, 1970)

#### Design and fabrication of sharp bend photonic crystal slab waveguides

(Massachusetts Institute of Technology, 2001)

A periodic arrangement of atoms in a crystal presents a periodic potential for electrons. The bragg diffraction of electrons from the atoms may lead to a band gap, which represents a range of frequencies the electrons ...

#### Physical limits of intrabody singalling

(Massachusetts Institute of Technology, 1997)
