B [right arrow] ([rho]/[omega]) [gamma] at BaBar
(Massachusetts Institute of Technology, 2007)This document describes the measurements of the branching fractions and isospin violations of the radiative electroweak penguin decays B [right arrow] ([rho]/[omega]) [gamma] at the asymmetric energy e+e PEPII collider ... 
Baffle material characterization for Advanced LIGO
(Massachusetts Institute of Technology, 2008)The transition to Advanced LIGO introduces new sensitivity requirements for the LIGO interferometers. When light scatters away from the main laser beam, then scatters off the beam tube and returns to the main beam, noise ... 
The ballast resistor : a simple dissipative structure.
(Massachusetts Institute of Technology, 1976) 
Ballistic electrons : microscopy, spectroscopy, devices and luminescence
(Massachusetts Institute of Technology, 2003)This thesis describes research to theoretically model and experimentally measure electronic systems which employ ballistic electron emission. First, a MonteCarlo framework for simulating electron injection from a tunnel ... 
Bayesian modeling of microwave foregrounds
(Massachusetts Institute of Technology, 2008)In the past decade, advances in precision cosmology have pushed our understanding of the evolving Universe to new limits. Since the discovery of the cosmic microwave background (CMB) radiation in 1965 by Penzias and Wilson, ... 
The behavior of O  C curves for contact binaries in the Kepler catalog
(Massachusetts Institute of Technology, 2013)In this thesis, we study the timing of eclipses for contact binary systems in the Kepler catalog. Observed eclipse times were determined from Kepler longcadence light curves and "observed minus calculated" (0  C) curves ... 
The behavior of thinfilm superconductingproximityeffect sandwiches in high magnetic fields
(Massachusetts Institute of Technology, 1978) 
Beyond the minimal supersymmetric standard model
(Massachusetts Institute of Technology, 1997) 
Binary star systems and extrasolar planets
(Massachusetts Institute of Technology, 2005)For ten years, planets around stars similar to the Sun have been discovered, confirmed, and their properties studied. Planets have been found in a variety of environments previously thought impossible. The results have ... 
Biologic effects of slow electrons
(Massachusetts Institute of Technology, 1936) 
A biomechanical study of a karate strike.
(Massachusetts Institute of Technology, 1977) 
Black hole singularities in the framework of gauge/string duality
(Massachusetts Institute of Technology, 2007)In this dissertation black hole singularities are studied using the AdS/CFT correspondence. These singularities show up in the CFT in the behavior of finitetemperature correlation functions. A direct relation is established ... 
Bohr's atomic model from the standpoint of the general theory of relativity and the calculus of perturbations
(Massachusetts Institute of Technology, 1924) 
Boosting (in)direct detection of dark matter
(Massachusetts Institute of Technology, 2017)In this thesis, I study the expected direct and indirect detection signals of dark matter. More precisely, I study three aspects of dark matter; I use hydrodynamic simulations to extract properties of weakly interacting ... 
Bose condensates and the atom laser
(Massachusetts Institute of Technology, 1998) 
BoseEinstein condensates in optical lattices : the superfluid to Mott insulator phase transition
(Massachusetts Institute of Technology, 2008)87Rb Bose Einstein Condensate in 3D optical lattice was studied in the regime of weak interaction(the superfluid phase) and strong interaction(the Mott insulating phase). The stability of superfluid currents was studied ... 
BoseEinstein condensation of atomic hydrogen
(Massachusetts Institute of Technology, 1999) 
BoseEinstein condensation of sodium atoms
(Massachusetts Institute of Technology, 1997) 
BoseEinstein correlations in 14.6A·GeV/c Si + Au [yields] 2K⁺ + X central collisions
(Massachusetts Institute of Technology, 1994) 
Bound states of pseudoDirac dark matter
(Massachusetts Institute of Technology, 2019)We study the boundstate spectrum in a simple model of pseudoDirac dark matter, and examine how the rate of boundstate formation through radiative capture compares to Sommerfeldenhanced annihilation. We use this model ...
