Probing the Mass Fraction of MACHOs in Extragalactic Halos
(American Astronomical Society, 1998)Current microlensing searches calibrate the mass fraction of the Milky Way halo that is in the form of massive astrophysical compact halo objects (MACHOs). We show that surveys like the Sloan Digital Sky Survey (SDSS) can ... -
Probing the mechanism of the bacterial Lipid II flippase, MurJ
(2023-11-21)Antimicrobial resistance (AMR) describes the ability of microorganisms such as bacteria to become insensitive to the growth-curbing effects of antibiotics. Resistant strains are able to grow and divide in the presence of ... -
Probing the neutral fraction of the IGM with GRBs during the epoch of reionization
(Oxford University Press, 2008-07-25)We show that near-infrared observations of the red side of the Ly alpha line from a single gamma-ray burst (GRB) afterglow cannot be used to constrain the global neutral fraction of the intergalactic medium (IGM), (x) over ... -
Probing the Onset of Quantum Avalanches in a Many-Body Localized System
(Springer Science and Business Media LLC, 2023-01-26)Strongly correlated systems can exhibit unexpected phenomena when brought in a state far from equilibrium. An example is many-body localization, which prevents generic interacting systems from reaching thermal equilibrium ... -
Probing the Spacetime around Sagittarius A* with Radio Pulsars
(American Astronomical Society, 2004)The supermassive black hole at the Galactic center harbors a bound cluster of massive stars that should leave neutron star remnants. Extrapolating from the available data, we estimate that similar to1000 radio pulsars may ... -
Probing the spacetime around supermassive black holes with ejected plasma blobs
(American Physical Society, 2015)Millimeter-wavelength very-long-baseline-interferometry observations of the supermassive black holes in Sgr A* and M87 by the Event Horizon Telescope could potentially trace the dynamics of ejected plasma blobs in real ... -
Probing the Spatio-Temporal Organizations and Dynamics of Gene Expression and DNA Replication in the Mammalian Cell Nucleus
(2015-05-15)The nucleus is an organelle of central importance to the mammalian cell. However, our understanding of the organizations and dynamics of many nuclear structures and processes remains inadequate, largely due to the difficulty ... -
Probing the Superfluid to Mott Insulator Transition at the Single Atom Level
(American Association for the Advancement of Science, 2010)Quantum gases in optical lattices offer an opportunity to experimentally realize and explore condensed matter models in a clean, tunable system. We used single atom–single lattice site imaging to investigate the Bose-Hubbard ... -
Probing the Universe after Cosmological Recombination through the Effect of Neutral Lithium on the Microwave Background Anisotropies
(American Astronomical Society, 2001)I show that neutral lithium couples strongly to the cosmic microwave background (CMB) through its 6708 Angstrom resonant transition after it recombines at z similar to 500. At observed wavelengths of less than or similar ... -
Probing the Wtb vertex structure in t-channel single-top-quark production and decay in pp collisions at s√=8 TeV with the ATLAS detector
(Springer Nature, 2017)To probe the Wtb vertex structure, top-quark and W-boson polarisation observables are measured from t-channel single-top-quark events produced in proton--proton collisions at a centre-of-mass energy of 8 TeV. The dataset ... -
A problem in theory
(Springer Science and Business Media LLC, 2019-02-11)A growing body of evidence suggests that humans are a new kind of animal—a product of genetic information from our parents and cultural information from our societies. This “Dual Inheritance Theory”, grounded in the ... -

Problem restructuring for better decision making in recurring decision situations
(Springer Science + Business Media, 2014)This paper proposes the use of restructuring information about choices to improve the performance of computer agents on recurring sequentially dependent decisions. The intended situations of use for the restructuring methods ... -
The Problemata as a Natural Philosophical Genre
(MIT Press, 1999)The Aristotelian corpus not only established for some two millennia the definitions and standards for many branches in the natural sciences, but also founded a genre which respected neither the disciplinary boundaries nor ... -
Problems at the Nexus of Geometry and Soft Matter: Rings, Ribbons and Shells
(2012-08-17)There has been an increasing appreciation of the role in which elasticity plays in soft matter. The understanding of many shapes and conformations of complex systems during equilibrium or non-equilibrium processes, ranging ... -
Problems in Signal Processing and Inference on Graphs
(2015-05-15)Modern datasets are often massive due to the sharp decrease in the cost of collecting and storing data. Many are endowed with relational structure modeled by a graph, an object comprising a set of points and a set of ... -
Problems in the dynamics of shells and time-optimal control: From abseiling spiders to singing saws
(2023-05-12)In the first part of this thesis, we study localized vibrational modes in shells with spatially varying curvature. In particular, we describe how localized modes arise in two musical instruments, the steelpan and the musical ... -
