Incoherent scatter radar detection of enhanced plasma line in ionospheric E-region over Arecibo
(Massachusetts Institute of Technology, 2006)A series of incoherent scatter radar (ISR) observation were conducted at the Arecibo Observatory from December 27, 2005 until January 3, 2006. From plasma line measurements that were taken during this radar campaign, we ... -
Influence of gene expression gradients on positional information content in fly embryos
(Massachusetts Institute of Technology, 2018)The concept of positional information was introduced to qualitatively explain how individual cells are involved in forming patterns. Recent experimental and theoretical developments have made studying specific biological ... -
Infrared photoconductive PbTe film processing and oxygen sensitization
(Massachusetts Institute of Technology, 2015)Infrared (IR) thermal detectors and photodetectors have significant applications including thermal imaging, infrared spectroscopy and chemical and biological sensing. In this work we focus on photodetectors, which typically ... -
Initial analysis towards a measurement of the branching fractions B [right arrow] [rho][gamma] and B [right arrow] [omega][gamma]
(Massachusetts Institute of Technology, 2006)The Standard Model of particle physics predicts the existence of the "Unitary Triangle," which graphically relates the matrix elements of the Cabbibo Kobayashi Maskawa matrix and describes the strength of transformations ... -
An injection-locked 674 nm laser for Strontium-88 ion trapping
(Massachusetts Institute of Technology, 2012)Energy levels of the valence electron of a single trapped ⁸⁸Sr+ ion can be harnessed as an effective qubit for quantum information processing. The qubit transition to a metastable energy state can be stimulated by a laser ... -
Instabilities of rotating jets
(Massachusetts Institute of Technology, 2004)When a jet of water is in free fall, it rapidly breaks up into drops, since a cylinder of water is unstable. This and other problems involving the form of a volume of water bound by surface tension have yielded a wealth ... -
Instrumentation and algorithms for electrostatic inverse problems
(Massachusetts Institute of Technology, 2001)This thesis describes tracking objects with low-level electric fields. A physical model is presented that describes the important interactions and the required mathematical inversions. Sophisticated hardware used to perform ... -
Intense spreading of radar echoes from ionospheric plasmas
(Massachusetts Institute of Technology, 2005)On December 25, 2004, a large-scale ionospheric plasma bubble was observed over Arecibo Observatory in Puerto Rico, inducing significant range spreading on ionograms. This phenomena may be explained by means of the E x B ... -
Interactions of neutrons with silicon CCD chips
(Massachusetts Institute of Technology, 2011)Dark matter makes up approximately 22% of the energy density of the universe and as much as 83% of its matter composition. Despite its ubiquitous nature, it remains incredibly difficult to detect due to the weakness of its ... -

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 ... -
Interrogating the void : the difficulty of extracting information from many-body systems
(Massachusetts Institute of Technology, 2011)In this thesis, I will explore some of the ways the information-theoretic properties of quantum many-body systems can be analyzed. I do this in two different settings. First, I will describe an approach to the "scrambling ... -
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. ... -

Investigating physical properties of novel carbon-based materials
(Massachusetts Institute of Technology, 2004)In this thesis, we present the results of studies of physical properties in three classes of novel carbon-based materials: carbon aerogels, single-walled carbon nanotubes, and high thermal conductivity graphitic foams. The ... -
Investigating the angle or response and maximum stability of a cohesive granular pile
(Massachusetts Institute of Technology, 2004)In this thesis, I investigate the static and dynamic properties of a granular heap made cohesive by an interstitial fluid. I present the results of experimental work measuring the maximum angle of stability and the angle ... -
Investigation of a possible test of Tst invariance.

Investigation of asymmetric plasma blob dynamics
(Massachusetts Institute of Technology, 2009)The dynamics of asymmetric blobs is investigated in the Versatile Toroidal Facility (VTF) at MIT. Blobs are local regions of enhanced plasma density. Blobs are relevant to several areas of physics research, including fusion ... -
Investigation of electron temperature gradient driven micro-reconnecting modes in toroidal high-energy plasmas
(Massachusetts Institute of Technology, 2007)Experiments carried out with magnetically confined, high temperature plasmas have revealed important effects that have yet to be justified by existing theory. In particular, there arises an anomalous particle inflow in the ... -
