The development of orogenic plateaus : Plateaus: case studies examining relationships between tectonics, crustal strength, surface deformation, and plateau morphology
… the uplift, deformation, and erosion of orogenic plateaus. The timing and mechanisms of uplift of the Tibetan Plateau and the Altiplano are the subject of ongoing debate. Central issues include the strength of the lower crust and the role of lower crustal flow, the relative importance of …

Evolutionary, Demographic, Physiological and Behavioral Contributors to Mortality Plateaus
… robust evidence for the existence of mortality plateaus, their underlying causes have been the center of heated debate for nearly fifteen years. First, mortality plateaus represent a challenge for evolutionary biologists concerned with the evolution of aging, since traditional forms of aging …

The role of wind and water in shaping earth's plateaus
… and water in shaping Earth’s Cenozoic orogenic plateaus - prominent high-elevation, low relief sectors in the interior of Cenozoic mountain belts. In particular, the feedbacks between surface uplift, the build-up of topography and ensuing changes in precipitation, erosion, and vegetation …

Chern-Simons theory of magnetization plateaus on the kagome lattice
… mapping we analyse the phases/magnetization plateaus that arise at the mean-field level and also consider the effects of adding fluctuations to various mean-fi eld states. Along the way, we show how to discretize an abelian Chern-Simons gauge theory on generic 2D planar lattices that satisfy …

Plateaus of freedom : nationality, culture and state security in Canada, 1927-1957
This thesis examines the relationship between national culture and state security in mid-twentieth century Canada. Using records opened through Access to Information it challenges received interpretations regarding the origins of official multiculturalism and federal cultural institutions. Drawing …

Phase anomalies and plateaus in auditory nerve fiber responses to high-frequency tones
Phase reversals and phase plateaus have been found in studies that measure motion of the basilar membrane (BM) at the base of the cochlea in response to high-level sounds above the characteristic frequency (CF). In contrast, such patterns have not been found in responses of auditory-nerve fibers …

Urban Plateaus: Alienation, Disappearance, and the Random Encounter in Post-1945 Literature and Film
… of which is composed of a diptych of two “plateaus.” “Alienation” investigates Sam Selvon’s <em>The Lonely Londoners </em>(1956) and Mathieu Kassovitz’ <em>La Haine</em> (1995), two works that feature groups of men living in former colonial European capitals—London and Paris—who, though …

Genetic and Life History Characteristics of Venustaconcha Ellipsiformis and Venustaconcha Pleasii (Bivalvia, Unionidae) in the Ozark Plateaus Region
… freshwater mussels in river systems of the Ozark Plateaus. Venustaconcha pleasii (White River system) exhibited fixed electrophoretic allelic differences from V. ellipsiformis (Osage and Meramec basins) at 3 of 11 loci, and a 3.9% sequence divergence (mtCOI gene, 330 bp). Shell size and shape also …

Braided stream deposition and provenance of the Late Cretaceous-Paleocene(?) Canaan Peak Formation, Table Cliff and Kaiparowits Plateaus, southwestern Utah
The Late Cretaceous to Paleocene(?) Canaan Peak Formation of southwestern Utah is comprised of approximately 100 m of cobble conglomerate and subordinate sandstone. Gravel deposition occurred during high-discharge periods within a Scott-type, perennial, braided fluvial system as longitudinal (Gm) …

Analyses of algorithm performance for an oversubscribed scheduling problem
… AFSCN scheduling search space is dominated by plateaus, due to both the discrete nature of the objective function and to the fact that the schedule builder converts multiple permutations into identical schedules. Each algorithm handles plateaus differently. Hill-climbing randomly walks on the …

La déclinaison de la variation. Sur la notion de multiplicité chez Gilles Deleuze
… journey through the Bergsonism, A Thousand Plateaus and Difference and Repetition, uncovers a double articulation for the deleuzian multiplicity. This double articulation is expressed in the two axes of thematization that we develop, namely coherence and inherence, or in other terms, a …

Model calculations of current and density distributions in dissipative Hall bars
… functions of the magnetic field B, with plateaus of finite widths and the well-known, exactly quantized values. We emphasize the close relation between these plateaus and the existence of incompressible strips, and we show that for B values within these plateaus the potential variation …

In Situ Ksat Measurements of Five Fragipan Soils
… area is located on the Springfield and Salem Plateaus, two plateaus of the Ozarks Plateau Province (Bretz, 1965). Using an instrument developed by Dr. Aziz Amoozegar called the Amoozemeter, data were collected on two horizons above the fragipan at three different sites of five soil series. The …

ANALYTICAL SOLUTION, AGENT BEHAVIORAL TRANSITIONS AND CLASSIFICATION STRUCTURES IN N-PERSON SOCIAL DILEMMA GAMES
… extending over all social games. Three plateaus are identified. It is found that the agents in each plateau have a significantly different behavior. The transitions between these plateaus are analyzed. Previous literature indicates that there are indeed transitions, but offers no …

Influence of Molecular Orientation and Surface Coverage of w-Functionalized Mercaptans on Surface Acidity
… 3-dodecyloxymercaptophenol clearly showed plateaus at low and high pH with a broad transition between the two plateaus. 4-dodecyloxymercaptophenol showed a clear plateau at low pH but not at high pH, although a transition was observed. Using infrared spectroscopy, it was further shown that …

PATTERNED BIOFILM FORMATION TO INVESTIGATE BACTERIA-SURFACE INTERACTIONS
… biofilms in the valleys between square shaped plateaus. In addition, there appeared to be a threshold dimension of a plateau to allow bacterial attachment and biofilm formation on top of the plateaus. The threshold was found to be 40 µm × 40 µm for inverted patterns used in this study. Inspired …

Evaluating the Feasibility of Transaction Scheduling via Hardware Accelerators
As single-thread performance plateaus, modern systems increasingly rely on parallelism to scale throughput. Yet, efciently managing concurrency—particularly in transactional systems—remains a major bottleneck. This thesis explores the feasibility of accelerating transaction scheduling via hardware, …
