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...
The reaction conditions for the synthesis of Cu-BTC (BTC = benzene-1,3,5-tricarboxylic acid) were elucidated using a continuous-flow microreactor-assisted solvothermal system to achieve crystal size and phase control. A high-rate synthesis of Cu-BTC metal-organic frameworks with BET surface area of more than 1600 m²/g (Langmuir surface area of more than 2000...

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....
The critical contribution of this dissertation is to provide a better
understanding of the fundamental Chemical Bath Deposition (CBD) growth
kinetic and mechanism for the well known II-VI semiconductor CdS using the
newly developed continuous flow microreactor. This continuous flow microreactor
provides the temporal resolution to control the homogeneous reaction...
CuInGaSe₂ (CIGS), a promising thin film solar cell material, has gained lots of
attention in decades due to its high energy conversion efficiency and potential lower
manufacture cost over conventional Si solar cells. As a cheaper processing method
compared to vacuum-based techniques, solution-based deposition has been
successfully applied to fabricate...
Photoluminescence (PL) materials have attracted a lot of attention in last several decades. Recently PL materials, which can convert low-efficiency Ultraviolet (UV) or Infrared (IR) light to high-efficiency visible light, have been widely applied in the research of improving conversion efficiency of solar cell. As one of the most common...
The primary goal of this thesis is to fabricate a magnetic film between the coplanar transmitted stripline for crosstalk suppression. Crosstalk is caused from undesired inductive and capacitive coupling of signals between two conductors. The effective crosstalk suppression results from the inductive coupling of circuit elements through the lossy properties...
There is an emerging interest in developing wearable electronics as a platform, which

photonics and optoelectronic...
As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...
