A Correlation Study of the a-b Ridge Breadth to Selected Bodily Dimensions

The correlation of the a-b ridge breadth to 12 anthropometric measurements was investigated in this study. The two samples used were 165 Armenians residing in Australia and 100 American Caucasians. Results of the analysis indicated that the a-b ridge breadth is correlated to seven specific body measurements. In order of decreasing correlation, they were wrist breadth, weight, stature, bicondylar femur, upper arm circumference, biacromial diameter, and calf circumference. It was also evident that bone was the only body size component that was correlated to the a-b ridge breadth

The Maximum Clique Problem: Algorithms, Applications, and Implementations

Computationally hard problems are routinely encountered during the course of solving practical problems. This is commonly dealt with by settling for less than optimal solutions, through the use of heuristics or approximation algorithms. This dissertation examines the alternate possibility of solving such problems exactly, through a detailed study of one particular problem, the maximum clique problem. It discusses algorithms, implementations, and the application of maximum clique results to real-world problems. First, the theoretical roots of the algorithmic method employed are discussed. Then a practical approach is described, which separates out important algorithmic decisions so that the algorithm can be easily tuned for different types of input data. This general and modifiable approach is also meant as a tool for research so that different strategies can easily be tried for different situations. Next, a specific implementation is described. The program is tuned, by use of experiments, to work best for two different graph types, real-world biological data and a suite of synthetic graphs. A parallel implementation is then briefly discussed and tested. After considering implementation, an example of applying these clique-finding tools to a specific case of real-world biological data is presented. Results are analyzed using both statistical and biological metrics. Then the development of practical algorithms based on clique-finding tools is explored in greater detail. New algorithms are introduced and preliminary experiments are performed. Next, some relaxations of clique are discussed along with the possibility of developing new practical algorithms from these variations. Finally, conclusions and future research directions are given

HUNK Phosphorylates Rubicon to Support Autophagy

Background: Autophagy is a catabolic cellular recycling pathway that is essential for maintaining intracellular homeostasis. Autophagosome formation is achieved via the coordination of the Beclin-1 protein complex. Rubicon is a Beclin-1 associated protein that suppresses autophagy by impairing the activity of the class III PI3K, Vps34. However, very little is known about the molecular mechanisms that regulate Rubicon function. Methods: In this study, co-immunoprecipitation and kinase assays were used to investigate the ability of Hormonally Upregulated Neu-associated Kinase (HUNK) to bind to and phosphorylate Rubicon. LC3B was monitored by immunofluorescence and immunoblotting to determine whether phosphorylation of Rubicon by HUNK controls the autophagy suppressive function of Rubicon. Results: Findings from this study identify Rubicon as a novel substrate of HUNK and show that phosphorylation of Rubicon inhibits its function, promoting autophagy

Catalysts for Conversion of Ethanol to n-Butanol in Water

The conversion of the greenhouse gas CO2 into a sustainable fuel source is a chemical approach to a wide-reaching ecological problem. Current efforts are being made to convert CO2 into ethanol. Ethanol is a fuel itself and can be used as a fuel additive to gasoline, but there are better fuel alternatives than ethanol. This work investigates the conversion of ethanol to the more useful n-butanol via the Guerbet process with organometallic catalyst design. This is done through the synthesis of ten distinct iridium and ruthenium catalyst candidates. Although other catalysts have shown some viability for this process under the required aqueous reduced temperature conditions, there is still much room for improvement.Bachelor of Scienc

Low-Temperature Glassy Response of Ultrathin Manganite Films to Electric and Magnetic Fields

The glassy response of thin films of La0.8Ca0.2MnO3 to external magnetic and gated electrostatic fields in a field-effect geometry has been studied at low temperatures. A hierarchical response with irreversible memory effects, non-ergodic time evolution, aging and annealing behavior of the resistance suggest that the dynamics are governed by strain relaxation for both electronic and magnetic perturbations. Cross-coupling of charge, spin, and strain have been exploited to tune the coercivity of an ultrathin manganite film by electrostatic gating.Comment: 4 pages, 5 figure
