Planarity has been successfully exploited to design faster and more accurate approximation algorithms for many graph optimization problems. The celebrated theorem of Kuratowski completely characterizes planar graphs as those excluding K_5 and K_{3,3} as minors. Kuratowski's theorem allows one to generalize planar graphs to H-minor-free graphs: those that exclude a...
The study of differentiation of integrals has led to the study of maximal functions. In the development of harmonic analysis, the most powerful result connected with Lebesgue's theorem was that of the Hardy-Littlewood Maximal Theorem. This maximal theorem implies Lebesgue's theorem, and the maximal function and its variants have played...
A decade after the School of Education at Oregon State University adopted a spiral model of curriculum for teacher education,
a study was conducted to determine if Instructional Media, one
thread of that model, was spiralled in the curriculum.
A survey was conducted of graduating seniors, using a questionnaire to...
The major purpose of this study was to assess the effectiveness of
interactive video in the teaching/learning process. More specifically,
a comparison was made of the relative effectiveness of interactive
video and linear video as delivery modes in the acquisition of basic
photography skills in an independent learning environment at...
A large number of experiments were done to detect and identify
one or more intermediates involved in coupling ATP synthesis to
electron transport. Using mitochondria from blowflies, addition of
ADP after a period of incubation with Pi³² was found to give rise to a
temporarily rapid esterification (the "ATP jump"),...
Incremental ADCs (IADCs) have many advantages for low-frequency high-accuracy data conversion—they are easy to multiplex between channels, need simpler digital decimation filter, and allow extended counting with a Nyquist-rate ADC. A single-loop incremental ADC was designed and fabricated in 90 nm for a biosensor interface circuit. It incorporates one integrator,...
Electron and neutron irradiation effects in InGaP/GaAs single heterojunction bipolar transistors are investigated in this thesis. Devices with different emitter sizes and grown by two different growth techniques were examined. Based on the physics of heterojunction bipolar transistors and concepts of radiation damage mechanisms, the irradiation effects were analyzed. The...
This paper describes an investigation of a matrix algebraic method to determine isomorphism in pairs of undirected graphs. The method is described in some detail. The theoretical as well as the practical difficulties are given. It is shown that the method works for some cases. When the adjacency matrix of...
Homeodomain transcription factors control developmental processes. They pattern body formation, specify cell lineages and switch the onset of gene regulatory cascades. Pitx2, a bicoid-related homeodomain transcription factor, is asymmetrically expressed in the left lateral plate mesoderm and mesoderm-derived tissues. Pitx2 null mice are characterized by failure of body wall closure,...
The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....
