Nested Well Plasma Traps
… positive and negative component in Penning type traps with nested electric potential wells are presented. Computational techniques for the self-consistent calculation of potential and plasma density distributions are developed. Analyses are presented of the use of nested well Penning traps for …

Bobcat traps and other theories
… theoretical and sociological framings, Bobcat Traps and Other Theories represents a multiscalar auto-theoretical account of my upbringing in a small, working-class community in rural Missouri. Through personal essays, cultural criticism, and archival research, I make excursions into my past, …

Neutrophil extracellular traps in periodontitis
… the role of neutrophil extracellular traps (NETs) in the pathogenesis of periodontitis. A fluorometric assay was developed for the in vitro quantification of NET release and used to assess relative levels in chronic periodontitis patients, indicating elevated release under several …

How to Overcome Poverty Traps by Education
The thesis addresses the question of how poverty can be overcome by education. The starting point is the following type of poverty trap: poverty forces parents to send their children to work to secure the survival of the household. Due to child labor, children do not attend school and do not form …

Fiber optic integration in planar ion traps
Atomic ion traps are are excellent tools in atomic physics for studying single ions. Accurate measurement of the ion's electronic state in these ion traps is required by both atomic clocks and quantum computation. Quantum computation with trapped ions can only scale to larger numbers of qubits if …

Theory and application of planar ion traps
… with electrodes in a plane. These planar ion traps are compatible with modern silicon microfabrication, and can be scaled up to large arrays with multiple trapping zones. We implement these designs on printed circuit boards with macroscopic ions, allowing us to study the traps while avoiding …

Catalytic Cracking Of Hydrocarbons With Novel Metal Traps
… FCCT (catalysts for FCC with "in situ metal traps"), were developed in this study to achieve high dispersion of passivators. FCCTs were extensively tested and demonstrated experimentally. On the strength of these results, it can be stated that high dispersion of the metal traps, using the "in …

Hydrodynamical simulations of dust traps in protoplanetary disks
Las teorías actuales de formación planetaria concuerdan que los planetas se forman dentro de discos de gas y polvo alrededor de una estrella jóven. Sin embargo, no es claro cuál es el mecanismo detrás de la formación planetaria. Entre los mecanismos propuestos podemos encontrar que se podrían …

Laserless slow atom source for loading atom traps
Permanent magnets are used to selectively remove the fast atoms from an atomic beam and to guide the remaining slow atoms into a trapping region. The permanent magnets establish a quadrupole field which extends along the axis of a bent vacuum nipple. A threshold velocity is set by the radius of …

One-dimensional Bose-Einstein condensates in micro-traps
… atoms are subsequently transferred to micro-traps generated by wires mounted on the atom chip and Bose-Einstein condensation has been achieved. The Bose-Einstein condensates (BECs) created in the micro-traps form in the one-dimensional Thomas-Fermi regime. The cross-over between …

Understanding organizational traps in implementing service-oriented architecture
… of SOA implementation and two organizational traps (technology learning trap and implementation effectiveness trap) associated with SOA implementation. The theory of the organizational traps can be generalized to a broad context of innovative IS implementation. Further, the theoretical causes …

Computational Investigation of Spin Traps Using Hybrid Solvation Models.
… phosphorylated analogues have been used as spin traps for the investigation of free radicals in biological systems. Theoretical work on these molecules suggests that there are important differences in their properties between biological systems and isolated molecules in the gas phase, most likely …

Microfabrication of surface electrode ion traps for quantum manipulation
… several series of surface electrode linear Paul traps made from different electrode materials, followed by the ion motional heating experiment results for these traps. We demonstrate that the ion motional heating strongly depends on fabrication process. In particular, we explore how grain size …

Quantum simulations with 8̳8̳Sr+̳ ions on planar lattice traps
… SSSr+ ions on microfabricated planar lattice traps. These types of quantum simulations help solve exponentially complex quantum systems, which are challenging to current classical computers. Porras and Cirac's work has shown that off-resonance laser light couples the internal states of the …

SHM Racer : dynamic race condition detection using shared memory traps
This project investigated different types of data races that can exist within C code, and then incrementally built a race condition detector, SHM Racer, using an assortment of thread safety violation/data race violation detection methods. The objective of this report was to demonstrate the …

Methods of single-molecule energy landscape reconstruction with optical traps
Optical traps facilitate measurement of force and position as single molecules of DNA, RNA, or protein are unfolded and refolded. The effective energy landscape of a biomolecule can be reconstructed from the force and position data, providing insight into its structure and regulatory functions. We …
