Building Information Modeling (BIM) provides automatic detection of design-related errors by issuing warning messages for potential problems related to model elements. However, if not properly managed, the otherwise useful warning feature of BIM can significantly reduce the speed of model processing and increase the size of models. As the first...
TAC is the most commonly used medication in post transplantation maintenance immunosuppression therapy. TAC lipophilicity and its erratic oral absorption especially in the presence of food intake result in great intra- and interpatient pharmacokinetic variations. Complicated dosing and frequent required therapeutic monitoring is thought to be the main cause of...
Two ground-based timber harvesting methods have been commonly used for beetle-kill salvage treatments after a bark beetle epidemic in northern Colorado. A lop and scatter method uses a mobilized stroke delimber to delimb and buck trees at the stump, leaving tree tops and limbs on the forest floor, while a...
Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...
The cysteine-rich protein (CRP) family is a subgroup of LIM domain proteins. CRP1, which cross-links actin filaments to make actin bundles, is the only CRP family member expressed in the CNS with little known about its function in nerve cells. Here, we report that CRP1 colocalizes with actin in the...
My thesis explains the several problems that arise when a person from a Western English speaking country goes to work as an English teacher at private institutes in South Korea. It is based on my own experiences when I worked as an English teacher at private institutes in South Korea...
The frequent misidentification of Asian garments in small museum collections indicated the need for a garment identification system specifically for use in differentiating the various forms of Asian clothing. The decision tree system proposed in this thesis is intended to provide an instrument to distinguish the clothing styles of Japan,...
Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM).
The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is...
Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...
The primary purpose of this study was to (1) develop methods for the analysis of and (2) provide information on the chemical nature of reducing ends in typical cellulose substrates used for the study of cellulolytic enzymes. The studies were designed such that values obtained for cellulose substrates were compared...
Hop (Humulus lupulus L. var. lupulus) is a diploid, dioecious plant with an extensive history of cultivation and use in brewing, as a textile, and for its therapeutic properties. Hop is prized for its ability to produce a variety of aromatic and flavor compounds, as well as compounds with anti-microbial...
We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Persistent and uncontrolled inflammation is the root cause of various debilitating diseases. Given that interleukin-1 receptor–associated kinase 4 (IRAK4) is a critical modulator of inflammation, inhibition of its activity with selective drug molecules (IRAK4 inhibitors) represents a promising therapeutic strategy for inflammatory disorders. To exploit the full potential of this...
The purpose of this thesis is to provide an estimate of sunk costs in the U.S. brewing industry and analyze the relationships among sunk costs, advertising, and concentration.

Peroxiredoxins (Prxs) make up an ancient family of enzymes that are the predominant peroxidases for nearly all organisms and play essential roles in reducing hydrogen peroxide, organic hydroperoxides, and peroxynitrite. Even between distantly related organisms, the core protein fold and key catalytic residues related to its cysteine-based catalytic mechanism have...
Emerging data showing the presence of atmospheric microplastics (MPs) has recently raised awareness surrounding the potential of human nanoplastics (NPs) exposure. Due to factors such as weathering, UV exposure, and other biodegradation processes, plastic pollution in the environment breaks down over time into micro (<5 micrometers) and nanoscale (<1000nm) particles....
The cereal pathogen Fusarium graminearum produces secondary metabolites toxic to humans and animals, yet coordinated
transcriptional regulation of gene clusters remains largely a mystery. By chromatin immunoprecipitation and high-throughput
DNA sequencing (ChIP-seq) we found that regions with secondary metabolite clusters are enriched for
trimethylated histone H3 lysine 27 (H3K27me3), a...

Compared to conventional amorphous silicon (a-Si) TFTs, amorphous metal oxide TFTs have superior device performance such as
higher mobility, better sub-threshold swing, and lower off-state current. Amorphous metal oxide TFTs have an additional advantage
on the device uniformity due to the lack of grain boundary issues in the poly-Si TFTs....

Peroxiredoxins (Prxs) are very effective peroxide reducing enzymes, but also are susceptible to being
oxidatively inactivated by their own substrates. The level of sensitivity to such hyperoxidation varies
depending both on the enzyme involved and the type of peroxide substrate. For some Prxs, the
hyperoxidation has physiological relevance, so it...
