Porter James McCumber : evolution of a senator
… about the early life and career of Porter James McCumber, who served North Dakota in the United States Senate from 1899-1922. Contributing to the lack of written material about the man is the fact that there are very few sources available concerning his social and political life. He left no …

Superconductor -Insulator Transition in Quasi-One-Dimensional Nanowires
… SIT are well described by the Langer-Ambegaokar-McCumber-Halperin theory of thermally activated phase slips. No resistance ""tails"" characteristic of quantum phase slips were observed. Wires in the insulating phase of the SIT follow the predictions of the theory of weak Coulomb blockade in a …

Measurements of superconducting phase gradients by a nanowire quantum interference device templated by DNA molecules
… based on an extension of the Langer- Ambegaokar-McCumber-Halperin theory of thermally activated phase slips. In addition, we also measure the effect of vortex motions on these oscillations and confirm the field dependence of the Campbell penetration depth.

Magnetic force microscopy studies of mesoscopic superconducting structures
… of TAPS and compare it to the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory for TAPS in 1D superconducting structures. Further, we use the SR model to qualitatively study the effects of a locally applied magnetic field on the phase slip rate in rings containing constrictions. The states with …

Novel applications of the Josephson Effect: Ferroelectric Characterisation and Capacitively Shunted Grain Boundary Junctions
… high temperatures. A hysteretic junction with a McCumber parameter of 1.01 at 72.3K, with a critical current of 451mA and a resistance of 0.56W was achieved for a junction shunted with a 150mm2 external capacitor with a 50nm SrTiO3 dielectric. The measured capacitance was less than that expected …

Rare-earth-doped gallium lanthanum sulphide glasses for mid-infrared fibre lasers
… the Füchtbauer-Ladenburg equation, and the McCumber theory. Twenty-one transitions with peak emission wavelengths longer than 2 µm were identified, seven of which have not been reported in a glass before. Some transitions overlap with the fundamental absorption bands of environmentally …

A Comparative Analysis of Traditional Versus Block and Accelerated Block Scheduled High Schools Over an Eight-Year Period in a Large Urban School District
This study compared traditional, A/B and accelerated block scheduling and its effects on student achievement and attendance by comparing the differences in student outcomes observed before and after the adoption of block/accelerated block schedules. The independent variable was the use of time in a …

Mechanically-Induced Osteocyte-Th17-Cell Signaling and Osteoclastogenesis
Repetitive mechanical loading can lead to microdamage in bone tissue. In order to prevent accumulation of microdamage, a repair mechanism known as targeted bone remodeling removes the damaged bone tissue and replaces it with new bone matrix.|Osteocyte apoptosis has been associated with fatigue …

Private Debt Syndicates: Governance, Networks, and Syndicate Structure
<p>I examine the primary market for syndicated private credit agreements to U.S. firms within the context of contract theory with information asymmetries between contracting parties in a repeated game. Specific governance mechanisms determine a firm's cost of borrowing in syndicated credit …

“I wyl poure out the wordes of sorrowe”: politics in the Protestant and Catholic settings of Psalms 51 and 79 during the English Reformation
The music of the Tudor era in England reflected the period’s political instability. This instability had its roots in, among other things, the religious movement known as the Reformation. Protestant and Catholic factions relied upon biblical texts, sermons, tracts and other circulating works to …

Differential cross sections for the reaction He[superscript 3] ([gamma],[rho]) H[superscript 2] from 45 to 150 MeV
Differential cross sections for the reaction He 3 (y,p)H2 were measured for photons of 45 to 150 MeV at five angular settings: (theta p , theta d) = (30°, 142°) I (60°, 106°), (90° I 75°), (120°, 47.5°), and (135°, 34.5°) in the laboratory. At ep of 60° and 90°, [equation] was obtained for photon …

Some effects of dimensionality and defects on superconductivity
This thesis reports some theoretical studies of superconductivity with reduced dimensions. After an intro- duction to the physics of superconductivity with reduced dimensions, we reports our studies in three main topics in this thesis. In Chapter 2, the resistance of superconducting thin wires with …
