Show moreAziridinium ions are valuable and important intermediates to prepare complex nitrogen containing compounds. Various enantiomerically enriched -haloamines were synthesized as precursors to generate aziridinium ions in situ. Optically active aziridinium perchlorates or triflates were prepared and characterized using 1H and 13C NMR. Regioselective and enantioselective ring opening reactions of aziridinium ions with diverse nucleophilies including cyanide, azide, amines, hydride and water were extensively studied. An efficient one-pot synthetic route to enantiomerically enriched alcohols and amine precursors was developed. Development of the adequate bifunctional chelators is a critical step for radioimmunotherapy (RIT) of cancer. The practical and scalable regiospecific ring opening reactions of aziridinium ions with macrocyclic amines were utilized for synthesis of a series of bifunctional ligands including 3p-C-NETA, C-NE3TA, 3p-C-NE3TA, 3p-C-DECA, 3p-C-DE4TA, an optically active (S)-C-NE3TA, and bifunctional DTPA analogues for RIT using 90Y and 177Lu. Preparation of bifunctional chelators that can rapidly form 64Cu complexes with high stability is an imminent goal for effective PET imaging. A series of NOTA and NE3TA-based chelators were prepared. NE3TA-based bile acid conjugates and NE3TA- based dual receptor-targeted conjugates were synthesized and possess potential for application of targeted PET imaging with 64Cu.

Show moreThe goal of IPRO 320 is to create an online professional network for school teachers at the kindergarten through twelfth grade level to allow for the sharing of ideas, lesson plans and other professionally relevant information. This is a continuing project which saw limited success in the previous semester in that a functioning web site was constructed based on surveys of public school teachers but it saw very little use. This semester, the planned approach is to build on the research generated last semester by performing additional market research with teachers. Following that, IPRO 320 will rework much of the previous web site by refining some of the features, adding additional ones as the research indicates and improving the website in general, both functionally and aesthetically.

Show moreA new technique to reconstruct an object or environment in 3D using a single moving camera was developed. The technique requires only one camera moving through the environment. Once a set of images or a video is captured, a point cloud and the camera path of the environment or the object can be generated. The camera has to be calibrated in advance. The procedure of 3D reconstruction consists of the SIFT feature matching algorithm, the Epipolar geometry reconstruction, fundamental matrix algebra, points cloud triangulation, and the estimation of the camera motion. The algorithm explored in this thesis is only based on visual information captured by a single moving RGB-camera.

Show moreComputer models can describe complicated physical phenomena. Due to the highly nonlinear and complex nature, they require specially designed experimental inputs. One direction of computer experiment design is orthogonal Latin hypercube design which is widely used. This thesis reviews the most resent methods of orthogo- nal Latin hypercube designs, their constructing algorithms and important theoretical properties. These designs are easy to construct and preserve the orthogonal and equally-spaced projections. With large number of factors, orthogonal Latin hyper- cube designs enable researchers to estimate uncorrelated rst-order regression e ects, as well as higher-order e ects. For large number of runs, we reviewed general design method to construct large orthogonal Latin hypercubes from small orthogonal Latin hypercubes. A similar construction method for nearly orthogonal Latin hypercubes was discussed as well.

Show morePositron emission tomography (PET) is an important molecular imaging modality. To develop new bifunctional chelators for use in more sensitive PET imaging, 64Cu-radiolabeled chelators have been investigated as promising PET agents. We synthesized and evaluated a macrocyclic chelator (NOTA)-based new bifunctional ligands with different coordination groups. New bifunctional chelators were evaluated for their radiolabeling efficiency with 64Cu, and in vitro complex stability of 64Cu-labeled chelators in human serum was also studied. 64Cu-labeled chelators was further evaluated for in vitro complex stability by EDTA challenge as a rigorous test of transchelation. As a result, chelator D, E, 3p-C-NE3TA, and 3p-C-NOTA were indicated as best chelators and have a promise for 64Cu-based PET imaging. Radioimmunotherapy (RIT) is a highly selective modality of cancer treatment and uses a radiolabeled chelator conjugated with monoclonal antibody. Our continued research of developing new RIT agents radiolabeled with 177Lu, different types of a macrocyclic based bifunctional chelators (DOTA, NOTA and NE3TA)- with variation of denticity, macrocyclic cavity, and bimodality were synthesized. Radiolabeling efficiency of chelators and in vitro complex stability of 177Lu-radiolabeled complex in human serum were evaluated. The effects of different pH and TLC solvents were investigated to confirm the best radiolabeling condition of new chelators with 177Lu. Furthermore, complex stability of 177Lu-radiolabeled chelators in a solution with excess EDTA and various metals was evaluated for transchelation. Therefore, the results of radiolabeling, serum stability and EDTA and metal challenge studies indicate that cavity size and ligand x denticity in chelators affected binding affinity to Lu(III) . 3p-C-DETA was identified as the best chelator for further research of RIT agent.

Show moreCognitive impairment in individuals with chronic pain is frequently observed and clinically significant (McCracken, & Iverson, 2001). It has long been recognized that emotional factors contribute to both patient perception of impaired cognition and verifiable cognitive impairment on testing (Burt, Zembar, & Niederehe, 1995). However, scientific consensus is lacking regarding how specific emotions, such as depression, anxiety, and pain catastrophizing impact cognition in chronic pain patients. Research seeking to clarify such relationships has been hampered by methodological shortcomings, which include limited sample sizes, non-objective measures, and failure to examine multiple emotional dimensions in unique samples (McCracken and Vowels, 2014; Moriarty, McGuire, & Finn, 2011). The present study examined factors that might contribute to cognitive impairment in this population using a sample of 78 chronic pain patients evaluated for surgical candidacy for spinal cord stimulator (SCS) implantation at the University of Illinois at Chicago. Use of such a sample ensured patients were wellmotivated to perform to the best of their ability, so as to increase their chance of being cleared for such a highly desirable procedure. Additionally, the vast majority of participants passed well-validated objective measures of effort. Hypothesized associations between attentional function as measured objectively by the RBANS attention index and a number of predictor variables: depression and anxiety, subjective pain experience, pain catastrophizing, somatization, and engagement in pain behaviors were not found, and subsequent analyses of proposed mediating relationships could not be performed. However, fully a third (35.9 percent) of our well-motivated sample did not show clinically significant impairment (below 85, or 1 SD below the mean), as was expected. Thus, it is possible that a well-motivated sample may have been less likely than samples used in previous investigations to show cognitive impairment overall. Strengths and limitations of the study are discussed, as well as clinical and research implications.

Show moreThe optimal performance of axial compressors is crucial in a number of appli- cations, including power plants and gas turbine engines. Their efficiency is limited by the onset of stall, when the pressure rise across the compressor drops suddenly and destructive flow patterns emerge. Because of this, all compressors operate at conditions away from the stall point, but with an accompanying penalty in efficiency. The objective of this study is to examine the detailed fluid dynamic processes lead- ing to stall and devise a scheme of active flow control to delay stall onset, allowing compressors to operate safely much closer to the stall point and at greater efficiency. This is done on the low speed axial compressor rig in the Fluid Dynamics Research Center at the Illinois Institute of Technology. Results indicated that the stall cell appears at a flow coefficient, φ = 0.292 and that it is small, located close to the casing, rotating with the rotor blade row, but at 55% of the rotor rotation rate. Detailed stall inception investigation revealed that small amplitude modal waves instigated flow breakdown upstream of the rotor blade row, causing a spike stall cell to develop. This spike cell rotates very quickly (70%) and grows rapidly into a finite stall cell, slowing its rotation rate as it becomes fully developed. Stagnation pressure in the wake of the rotor blades was phase locked to both the rotor and stall cell rotation, allowing phase-averaging techniques to reveal the averaged stall cell structure. A new actuator was designed for rotating stall control. Based on the stall inception results, a disturbance rejection scheme was devised to interact with the incipient stall cell, preventing its growth into a finite stall cell. The single blade was studied in a number of open loop control experiments, which indicated that pulsing at 2psi over a range of frequencies can inhibit stall inception, extending the operating range by 0.4% mass flow, thus stabilizing a previously unstable operating point.

Show moreSystems with high steady-state multiplicity and rich dynamic behavior are difficult to investigate using conventional reductionist methods. A network of more than five reactors hosting cubic autocatalytic reactions may potentially have more than 101 steady states and many distinct dynamic regimes, all for the same parameter set. This paper discusses how the static complexity of such systems can be measured to give a holistic picture. To achieve this, stochastic simulations were performed to statistically determine the bifurcation structure of the system, and the gathered information is summarized using a measure akin to fractal dimension. With this measure, the growth of static complexity is investigated as a function of the network size.

Show moreContraction of the DLM1 flight muscles of the Hawmoth, Manduca sexta are synchronous with the nervous impulse stimulation like mammalian skeletal muscle. With cardiac-like behavior, DLM1 muscle of Manduca sexta can be a useful model to resemble mammalian cardiac muscle. Asynchronous flight muscles, like Lethocerus and Drosophila flight muscle, can only extend a few percent. But Manduca flight muscle has the ability to extend at least 100% in vitro and 9% in vivo. Very little is known about the protein composition and physiological behavior of Manduca flight muscle. Hence the length-tension behaviors of the DLM1 muscle of Manduca sexta are of considerable interest. In this experiment, we used PPi to remove thick filament in the sarcomere and focus on the passive tension generated by elastic proteins (projectin, kettin and sls proteins) in the sarcomere. The results showed elastic proteins (projectin, kettin and sls proteins)-based passive tension play a major role on muscle passive force in DLM1 muscles of Manduca sexta. We also tested a new way to prepare chemically skinned muscle samples where the dorsal and ventral muscle samples are pinned still in their shell on plates during the skinning step. In addition, preliminary experiments attempting to purify the DLM1 muscle proteins of Manduca sexta, fast protein liquid chromatography was used. Then 1% vertical SDS-agarose gel electrophoresis (VAGE) and 4-20% SDSPAGE gel are used to detect the samples after purification. We successfully purified 900kDa projectin and 700kDa kettin, which are major elastic proteins and useful for further research.

Show moreAlthough the Fama and French’s three factor model is now the most popular replacement for CAPM in corporate finance and investment management, the exclusion of financial firms can be questioned on both theoretical and empirical grounds. Financial firms are around 19 percent of the value of the U.S. stock market. The financial service industry is the major industry in many large U.S. cities including New York, Chicago, Los Angeles and Miami in that their GDPs of financial services for each city are more than 23 percent. Also, there is no theoretical reason for excluding financial firms. Modigliani and Miller [31] [32] suggest that leverage affects beta, but it does not invalidate the capital asset pricing model. It would therefore be more satisfying if the pricing model applied generally, rather than being restricted to nonfinancial corporations. From this consideration, this paper assesses the validity of size and value risk as common risk factors to measure of expected equity returns in financial companies based on the fact that Fama and French [11] [12] excluded financial firms in their study of the cross-section of expected stock returns. The findings from empirical asset pricing tests suggest that size and value risk premia commonly exist in both nonfinancial and financial firms even if two factors are less explicable in financial firms, that an interest rate risk premium (ΔL/L) which defined as a financial firm specific risk factor only appears in financial companies.

Show moreMotivated by real world applications, three topics - deterministic quantities, uncertainty quantification and data assimilation, are considered for non-Gaussian stochastic dynamics. More specifically, three problems are formulated to investigate non-Gaussian dynamics: (i) exit problem and time-dependent probability density; (ii) parameter and function estimation for stochastic differential equations driven by L´evy motion; and (iii) nonlinear data assimilation to infer transition phenomena. First, numerical algorithms are developed to study important metrics: mean exit time, escape probability and time-dependent probability density, which can be utilized to quantify dynamical behaviors of stochastic differential equations with non- Gaussian -stable L´evy motion. Moreover, detailed numerical analysis work is done to ensure the algorithms accurate, fast and stable considering the singular nature of the L´evy jump measure. Second, new approaches on parameter and function estimation in stochastic dynamical systems are devised. Taking advantage of observations on mean exit time, escape probability or probability density, model uncertainty can be quantified by some optimization methods. These methods are beneficial to systems for which mean exit time, escape probability or probability density are feasible to observe. Finally, nonlinear data assimilation on non-Gaussian models is studied. For continuous-discrete filtering, a recursive Bayesian approach is used, and for continuous filtering, Zakai equation is solved to provide the system state estimation. In both cases, time-dependent transition probability between metastable states are investigated. xiMotivated by real world applications, three topics - deterministic quantities, uncertainty quantification and data assimilation, are considered for non-Gaussian stochastic dynamics.

Show moreTwin jet plumes on aircraft can couple, producing dynamic pressures significant enough to cause structural fatigue. For closely spaced jets with a moderate aspect ratio (e.g. 5), previous work has established that two coupling modes (antisymmetric and symmetric) are kinematically permissible. However, the dynamics of twin-jet coupling have remained unexplored. In this paper a more fundamental assessment of the steady and unsteady aspects of twin-jet coupling is attempted. While we document and discuss the nozzle spacings and Mach numbers over which phase-locked coupling occurs, our concentration is much more on answering the following questions: (a) What mechanism causes the jets to couple in one mode or the other? (b) Why do the jets switch from one mode to another? (c) Are the two modes mutually exclusive or do they overlap at the transition point? Our results reveal, among many things, the following. (i) For very closely spaced twin jets in the side-by-side configuration phased feedback based on source to nozzle exit distance of adjacent jets does not fully explain the coupling modes. However, the 'null' phase regions surrounding the jets where the phase of an acoustic wavefront (arriving from downstream) does not vary appears to correlate well with the existence of the symmetric mode. When the 'null' regions of adjacent jets do not overlap antisymmetric coupling occurs and when they do overlap the jets couple symmetrically. We provide a simple correlation using a parameter (a) that can be used as a simple test to determine the mode of coupling. (ii) The switch from the antisymmetric to the symmetric mode of coupling appears to occur because of an abrupt shift in the effective screech source from the third to the fourth shock, which in turn causes the 'null' phase region surrounding the jets to grow abruptly and overlap. (iii) The two modes are mutually exclusive. Our results provide considerable insight into the twin-jet coupling problem and offer hope for designing twin-jet configurations that minimize damage to aircraft components.

Show moreSurvivability refers to the capability of a system to ful ll its mission, in a timely manner, in the presence of attacks, failures, or accidents. For many distributed systems, ensuring their survivability under directed attacks is critical. Tra c analysis, conducted by the attacker, could reveal the protocol being carried out by the components. Furthermore, having inferred the protocol, the attacker can use the pattern of the messages as a guide to the most critical components. In this thesis, we rst thwart these directed attacks by using message forwarding to reduce tra c di erences, thus diverge attackers from directed attack to random attack, which probabilistically prolongs the availability of important components in the system. Then, we investigate how to improve system availability when the system is under random attack. Although the attackers cannot di erentiate the di erences between critical and non-critical components, they can intelligently decide how to invest their resources by rationally selecting the number of components to attack. Under this case, how to maintain system reliability is another challenging issue. This thesis further discusses the attacker-defender problem and analyzes how to maximize system reliability under rational attacks. When one or more system processing elements are compromised by attackers, how to select applications and deploy their tasks to the remaining processing elements so that the system availability is maximized is also investigated in this thesis. To be more speci c, we assume the applications may have di erent values towards system availability and may or may not share the same composing tasks, and we presented two di erent approaches, i.e., Genetic Algorithm (GA) based approach and Max-Min-Min based approach to solving this problem. GA-based approach produces near optimal solutions and it can be used o -line when the performance is important and timing complexity is not the primary concern. While the Max-Min-Min based approach is computationally e cient and it is used when the timing is critical.
