Kepler Objects of Interest Cumulative Table

NASA Exoplanet Archive
The Kepler Objects of Interest (KOI) cumulative table gathers information from the individual KOI activity tables that describe the current results of different searches of the Kepler light curves. The intent of the cumulative table is to provide the most accurate dispositions and stellar and planetary information for all KOIs in one place. All the information in this table has provenance in other KOI activity tables.

Nonlinear Optics and Wavelength Translation Via Cavity-Optomechanics

Jeffrey Thomas Hill
The field of cavity-optomechanics explores the interaction of light with sound in an ever increasing array of devices. This interaction allows the mechanical system to be both sensed and controlled by the optical system, opening up a wide variety of experiments including the cooling of the mechanical resonator to its quantum mechanical ground state and the squeezing of the optical field upon interaction with the mechanical resonator, to name two. In this work we explore...

Characterization of Diverse Megathrust Fault Behavior Related to Seismic Supercycles, Mentawai Islands, Sumatra

Belle Philibosian
Long paleoseismic histories are necessary for understanding the full range of behavior of faults, as the most destructive events often have recurrence intervals longer than local recorded history. The Sunda megathrust, the interface along which the Australian plate subducts beneath Southeast Asia, provides an ideal natural laboratory for determining a detailed paleoseismic history over many seismic cycles. The outer-arc islands above the seismogenic portion of the megathrust cyclically rise and subside in response to processes...

Advanced Density Functional Theory Methods tor Materials Science

Steven Brian Demers
In this work we chiefly deal with two broad classes of problems in computational materials science, determining the doping mechanism in a semiconductor and developing an extreme condition equation of state. While solving certain aspects of these questions is well-trodden ground, both require extending the reach of existing methods to fully answer them. Here we choose to build upon the framework of density functional theory (DFT) which provides an efficient means to investigate a system...

Positions, flux densities,...

Identification of Fucose-α(1-2)-Galactose Binding Proteins in the Mammalian Brain

Arif Wibowo
Fucose-α(1-2)-galactose (Fucα(1-2)Gal) carbohydrates have been implicated in cognitive functions. However, the underlying molecular mechanisms that govern these processes are not well understood. While significant progress has been made toward identifying glycoconjugates bearing this carbohydrate epitope, a major challenge remains the discovery of interactions mediated by these sugars. Here, we employ the use of multivalent glycopolymers to enable the proteomic identification of weak affinity, low abundant Fucα(1-2)Gal-binding proteins (i.e. lectins) from the brain. End-biotinylated glycopolymers containing...

Synthetic Molecular Machines for Active Self-Assembly: Prototype Algorithms, Designs, and Experimental Study

Nadine L. Dabby
Computer science and electrical engineering have been the great success story of the twentieth century. The neat modularity and mapping of a language onto circuits has led to robots on Mars, desktop computers and smartphones. But these devices are not yet able to do some of the things that life takes for granted: repair a scratch, reproduce, regenerate, or grow exponentially fast–all while remaining functional. This thesis explores and develops algorithms, molecular implementations, and theoretical...

An Economic Approach to Consumer Product Ratings

Dustin Hughes Beckett
In three essays we examine user-generated product ratings with aggregation. While recommendation systems have been studied extensively, this simple type of recommendation system has been neglected, despite its prevalence in the field. We develop a novel theoretical model of user-generated ratings. This model improves upon previous work in three ways: it considers rational agents and allows them to abstain from rating when rating is costly; it incorporates rating aggregation (such as averaging ratings); and it...

me101 is a new allele of rad-51

Baptiste Roelens, Karl A Zawadzki & Anne M Villeneuve
The me101 allele was isolated in a genetic screen for mutants with an altered number of GFP::COSA-1 foci, which mark the sites of crossovers in C. elegans germ cells (ROSU et al. 2013). After multiple rounds of outcrossing, we confirmed that me101 mutants were defective in some aspects of meiotic prophase, as late pachytene me101 mutant meiocytes failed to form the six GFP::COSA-1 foci observed in wild-type late pachytene meiocytes (Fig 1.A). We also observed...

Towards Understanding the Mixing Characteristics of Turbulent Buoyant Flows

Phares Lynn Carroll
This work proposes a new simulation methodology in which variable density turbulent flows can be studied in the context of a mixing layer with or without the presence of gravity. Specifically, this methodology is developed to probe the nature of non-buoyantly-driven (i.e. isotropically-driven) or buoyantly-driven mixing deep inside a mixing layer. Numerical forcing methods are incorporated into both the velocity and scalar fields, which extends the length of time over which mixing physics can be...

Dynamics of Cell–Matrix Mechanical Interactions in Three Dimensions

Jacob K. Notbohm
The forces cells apply to their surroundings control biological processes such as growth, adhesion, development, and migration. In the past 20 years, a number of experimental techniques have been developed to measure such cell tractions. These approaches have primarily measured the tractions applied by cells to synthetic two-dimensional substrates, which do not mimic in vivo conditions for most cell types. Many cell types live in a fibrous three-dimensional (3D) matrix environment. While studying cell behavior...

Linear and Non-linear Interactions in a Rough-Wall Turbulent Boundary Layer

Jonathan P. Morgan
This thesis explores the linear and non-linear interactions which take place in a rough-wall turbulent boundary through experiments and modeling. In order to derive physics-based models for the relation between roughness geometry and flow physics, two very simple periodic roughnesses were 3D printed and placed in a boundary layer wind tunnel for separate experiments. Hot-wire measurements were taken at a grid of points within a single period of the roughness in order to map the...

Overexpression of hindsight in sensory organ precursors is associated with a transformation of campaniform sensilla to microchaetae in the Drosophila wing

Krzysztof Szablewski & Bruce H. Reed
The adult Drosophila wing blade contains sense organs known as campaniform sensilla.  These cellular structures sense pressure or strain in the wing during flight and provide neural feedback required for coordinated wing movements (Bartussek and Lehmann, 2016).  The dorsal surface of the wing blade includes three campaniform sensilla along wing vein L3, two on the first longitudinal vein near the tip of the costa, and a single sensillum on the anterior cross vein.  Other campaniform...
