Show moreConcrete is one of the most widely used construction materials in the world, and Portland Cement is the most commonly used cement in the industry. Manufacturing materials are dependent on research and industry specification standards. This report focuses on current innovations in concrete developments, with a specific emphasis on Aluminosilicate or ‘geopolymer’ cements and their possible implications on architecture in the United States. Aluminosilicate cements are currently being researched worldwide and have been implemented in a couple of countries as a replacement for portland cement. It’s one of many sustainable cement solutions, but unlike others, provides enhanced characteristics while remaining in the same price range as ordinary portland cement mixtures. This technology uses no limestone or water thus eliminating the need for high amounts of energy use in the production of its initial ingredients. Introducing new construction materials is challenging, especially to a well established concrete industry such as that of the United States. Precast concrete offers an ideal medium for new concrete materials and their introduction into common practice. More sustainable and durable materials are becoming available, changing construction processes and have the possibility to affect the further evolution of architectural design. This report articulates these advancements and the importance of architectural involvement within the United States construction industry.

Show moreDiffuse large B cell lymphoma (DLBCL) is a heterogeneous malignancy distinguished by aggressive clinical symptoms and abnormal B cell receptor signaling. Current treatments are shown to have refractory or relapsed outcome post initial treatment signifying the need for novel chemotherapeutic targets. ERM family proteins have been shown to modify B cell immune response to antigen. Previous studies in our lab reveal that ERM proteins are phosphorylated in both DLBCL tumors and cell lines. Alteration of ERM function with Ezrin dominant negative mutant (EZ-DN) decreased the growth of DLBCL cells. This reduction of cell growth is thought to be mediated by interfering with the NF-kB and PI3K signaling. To understand the molecular mechanism of EZ-DN in a time dependent manner without impairing the cell growth immediately, Tet-on 3G based inducible expression system was utilized. Molecular cloning of the EZ-DN into the inducible system was performed, sequencing confirmed the insert of EZ-DN into the response vector (pTRE3G-BI-ZsGreen1) at desired locations. We have further evaluated the effect of doxycycline on the expression of fluorescent protein (Zsgreen1) and EZ-DN, also optimized its concentration for maximal expression of the proteins in DLBCL cell lines. Higher dose of doxycycline (above 5 μg/ml) induced reduction in cell viability. The expression of EZ-DN and Zsgreen1 is considered to be much stronger in the double stable cell lines containing the co-transfected regulator vector (pEF1α- TET3G) and response vector (pTRE3G-BI-ZsGreen1) with a selection marker. In conclusion, our data demonstrated the successful creation of inducible system that expresses EZ-DN, which can be employed to validate Ezrin as a therapeutic target in DLBCL.

Show moreThe thesis considers the problem of pricing different types of mountain range options by quasi-Monte Carlo simulation. Principal component analysis (PCA), also known as the singular value decomposition (SVD), has been applied widely to reduce the quasi-Monte Carlo sampling error in many financial problems. This is especially true for pricing single asset options. The purpose of this thesis is to investigate whether the singular component decomposition offers advantages for pricing mountain range options, which are exotic options based on multiple underlying assets. We consider our simulation in a complete, standard Black-Scholes market which has constant risk-free interest rate and covariance matrix. There are main two types of mountain range options simulated in this thesis: Altiplano and Himalayan. Key words : Mountain Range Option; Quasi-Monte Carlo; Singular Value Decompo- sition; Altiplano Option; Himalayan Option

Show moreComputer-mediated communication is becoming the most convenient and important way of sharing and exchanging information. The large volume and diversity of user generated content as well as pervasive user opinions on the web make existing text processing methods ine cient and ine ective. Hence, there is a need for better ways of analyzing and utilizing user generated content. My thesis focuses on user generated data and is composed of two main parts: sentiment analysis and content analysis. I present a case study in which I use machine learning techniques to analyze real-world survey responses. Supervised techniques are exploited to classify customers' loyalty based on their comments and estimate a Net Promoter Score (NPS). NPS is a crucial indicator which has been used as a means of measuring survey results with a single estimator. I de ne three patterns to support generalized sentiment-bearing expression extraction, and design a set of heuristic rules to detect both explicit and implicit negations. By altering existing dependency with detected negations and generalized sentiment-bearing expressions I am able to construct more accurate sentiment features. Our results demonstrate that generalized dependency-based features are more e ective when compared to standard features. For content analysis, the thesis addresses the problem of user generated content summarization. I focus on two sub-problems: how to summarize the novel information from user generated content and how to present the evolutionary theme threads from temporal text collections with summaries. I design two speci c topic models for these two summarization tasks respectively. To discover similar and supplemental topics in user opinions with respect to the descriptive text provided by a publisher, I propose a semi-supervised generative model by casting the local publishers descriptive elds as a prior of a resembling topic. The most representative sentences in user opinions are classi ed based on their sentiment and used to construct a summary of x the comments. To track changes of topics in temporal text collections, I extend the probabilistic model to sentence level and use name entity to make the extracted theme thread easier to understand. Experimental results demonstrate the e ectiveness of the proposed models.

Show moreProficiency Testing (PT) is an external assessment program to measure the performance of a laboratory. Freeze drying is a well-known dehydration process to produce food products or bio-products with high quality. In this study, freeze dried PT samples containing bacterial strains were prepared and examined for retention of the viability of the bacteria. Ground beef and skim milk were inoculated with bacteria related to food safety, either with or without cryoprotectants, and then freeze dried. The effects of trehalose solution, milk-based mixture, and microbial freeze drying buffer on lyophilized E. coli strains recovery in ground beef were determined. The freeze dried samples were packaged in heat sealable polyethylene terephthalate bags, and stored at either 24 °C or 5 °C in dark. The viability of the freeze dried bacteria was tested during storage. Gram-positive bacteria survived better than Gram-negative bacteria during lyophilization and storage. Skim milk provided better protection of bacteria than ground beef during lyophilization and storage. None of the cryoprotectants examined improved survival of E. coli strains in ground beef during lyophilization and storage. The viability of a cocktail of Gram-positive and Gram-negative bacteria freeze dried in skim milk was stable over 60 days storage at 5 °C in dark.

Show moreAfter comparison of inorganic, hybrid and organic porous materials, tetrazine based organic porous material was chosen as a target material since it was rigid material providing micro- to mesoscale pores and could do post-synthetic modifications through inverse electron demand Diels-Alder Reaction with different dienophiles. Such networks own the potential as catalysts after modifying with different metal chelation sites. Here, three strategies were provided to synthesize such materials. During of construction of building blocks through double Diels-Alder Reaction, reactivities of tetrazines and dienophiles were studied. The coupling study provided the information of which type of coupling reaction could be used as well as how it was proceeded. The Direct synthesis of tetrazine-based network through formation of tetrazines then broadened the variety materials that could be synthesized.

Show moreDye-Sensitized Solar Cells (DSSCs) have been investigated using various methods including: varied illumination density, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and equivalent circuit models. Under various illumination conditions, DSSCs were affected by many factors: exposure time, surrounding temperature, light intensity and UV (ultraviolet) radiation. In order to understand and identify aging phenomena, as well as ionic and electronic processes, a number of physical and electrochemical experiments were performed. The internal resistances among the components of DSSCs showed distinct features under different experimental conditions. For long-term stability and high performance of DSSCs, it is necessary to investigate the characteristics of these internal resistances and develop methods to reduce them. By using electrochemical impedance spectroscopy (EIS) and equivalent circuit models, it was possible to demonstrate the electrochemical phenomena and degradation characteristics of DSSCs.

Show moreAs computing technology has become an essential tool for law enforcement, crime mapping has evolved from the use of pushpins on paper maps to the use of computerized geographical information systems (GIS). The use of GIS permits real-time display of maps showing crime “hotspots,” facilitating the implementation of specific crime prevention strategies targeting the affected locations. Until recently, crime maps merely presented a summary of previous crime incidents; however, as part of a new concept called “predictive policing”, efforts are now underway to produce crime maps that are predictive, highlighting geographical regions that an algorithm determines are likely to experience abnormally high (or low) crime levels in the near future. Traditionally, crime maps are produced by representing crime data (a spatiotemporal point process) on a uniform grid, similar to the way in which pixels are used to represent digital images. However, the problem of predictive policing places new demands on mapping, raising questions about how maps should ideally be made. For example, there is considerable uncertainty concerning how best to optimize the grid spacing in a predictive map: If the pixels are too small, the past data required to predict future crime will be too sparse to enable good prediction performance; if the pixels are too large, each prediction will cover too large of a geographical region, the behavior of crime within the region may be heterogeneous and not well captured by a single predictive model, and coarse-scale predictions will not be sufficiently specific to be acted upon by police. In this thesis, a novel method for representing crime mapping data is proposed, in which the conventional pixel representation is replaced by a non-uniform sampling scheme based on mesh modeling, an approach that was first proposed in the context of image processing by members of our research group. In the present context, the goal is to adapt the spatial sampling to the local density of available training data in an effort to equalize prediction performance across a predictive map while accurately representing the spatial density. Geographical areas having few crimes will be represented more coarsely by this approach, with high-crime areas being represented at a fine spatial scale. We used various metrics to test the proposed approaches based on real and simulated crime-incident data for the City of Chicago. The results of our experiments demonstrate that the proposed method is a promising framework for predictive crime mapping. In future work, our hypothesis about the value of spatial sampling adaptation will be tested through the use of the proposed method within a complete spatio-temporal prediction algorithm. Although this thesis focuses only on representation of crime data, we anticipate that the proposed method may find application in other density estimation or mapping problems in which smooth densities are to be approximated from spatial point-process data.

Show moreMany species of birds in Americas vocalize during nocturnal migration ights. Acoustic detection and classi cation of the calls show potential for study of the nat- ural history of these migrant birds. In particular, information about the species' composition and number of birds involved in migration movements may be obtain- able through acoustic techniques. Other methods such as radar monitoring may have capability only to assess the number, but not the composition. Mel Frequency Cep- stral Coe cients-Gaussian Mixture Model-based methods, Mel Frequency Cepstral Coe cients-Hidden Markov Model-based methods and spectrogram correlation-based methods have been proposed to automate the recognition/classi cation of the noctur- nal ight calls. Here we investigate the impact of choice of time-frequency representa- tions on Mel Frequency Cepstral Coe cients-Hidden Markov Model-based classi er and correlation based classi er performance. We use a collection of recordings of nocturnal ight calls of several species of thrushes and other bird species with similar calls to evaluate and compare classi ers.

Show moreWaukegan is a place that has a strategic location. Not just because it is in the middle of two important cities like Chicago and Milwaukee, but because of its proximity to the lake (which is the most desired location for condos and public activities) and all the existing train systems that can help to develop the area as a public transit oriented city. Because of this, Waukegan has a good possibility to become one of the most desirable places to live, but the lack of intervention; coordination and initiative from the city in the past decades have left the place abandoned. People and companies are leaving, and initiatives to redevelop are still known for its residents and are taking too long. For Waukegan the most important strategy is to bring life back to its downtown. After that, some activities could cross easily to the water front, making people aware of the endless possibilities that the area offers not just for dwelling units, but for commercial, recreational and even educational purposes. (Research center and possible school) For the lake front, the strategy should be different for some spaces depending on the surrounding areas and the character that they could have. A strategy is to bring activities that can complement life in the city, for example: theaters, sports centers, hotels etc. Adding 9,000 people to the total people will give the option of have new routes for public transportation, new jobs and new and more equipment for recreational spaces. Apart from that, the unification of the two areas: down town Waukegan and the water front are important in order to understand the place like one. The fact that the highway and the railroad stand are in the middle of both, just creates a strong division. On the top of that, there is no reason to cross over to go to the beach area. If we consider that highway traffic is low and the railroad could be moved (not erase, but moved. Because there is still the necessity for it) the connection between both places could be more clear and strong, not just for people but for cars. This strategy will be critical at the time of unification of the area. In addition Waukegan has a population of 44.8 % Hispanic, 30.9% White Non-Hispanic. With an estimated median household income in 2007: $45,548. This shows that Waukegan is mainly supported by low income families and they are mostly of Hispanic origin. The idea is not to completely change the city but to support their business and culture making places into an attraction for cultural interchange. One of the main purposes of the new vision city is equality. Not thinking that in order to make a place better (more beautiful or desirable) we have to kick out its old residents. People create ties to the place they live. This could be an incentive to bring the community together in order to improve the environment. Also the addition of the new research center in between down town and the new lake front development will help to bring new uses to the area. The research center will offer new jobs and a choice for some people coming from outside to live in the locality. Close to the research center, the new lake front neighborhood will offer an area with several entertainment spaces and then the option to live closer to this location or in a more quiet and familiar area. The research center will have the possibility for future expansion that could be an education center related to the work that is done there. This will bring students to the area and more diversity. There are many good reasons to stop abusing the car use and make use of the many alternatives, but in the end we design and negotiate the same old fashioned neighborhoods. It is because we have not solved the conflict of interest between a better envi-ronment and a better economy. The problem is that in the end people will opt for those places with more commodities and that includes the car.

Show moreResearch has shown that cancer can have a detrimental impact on patients’ psychological and psychosocial functioning in addition to affecting physical health. Health-related quality of life (HRQOL) is a construct that captures patients’ adjustment in the realms of physical, psychological, social and functional well-being. Not only are patients impacted by a diagnosis of cancer, but it has been widely observed that the adjustment and overall well-being of patients’ families, and especially their spouses, can be impacted as well. Furthermore, links have been observed between patients’ and spouses’ mental and physical health during the experience of coping with cancer, suggesting that spouses may influence each others’ well-being. Given this evidence of cross-partner influence and the strong support for the impact of social support on well-being in the context of cancer, marital quality has been studied as a variable that could impact partnered individuals’ mental and physical health. The present study used a sample of newly-diagnosed cancer patients and their partners (N = 87 pairs) to examine the relationship between cancer patients’ self-reported HRQOL and their self-reported marital quality; as well as to examine the relationship between patients’ HRQOL and their partners’ reported marital quality. Gender was explored as a moderator of these relationships given that the available research is equivocal in regards to how gender influences adjustment to chronic illness, especially within dyads. Additionally, the relationship between patients’ and partners’ reports of marital quality was explored. Support was found for the proposed link between patients’ and spouses’ reports of marital quality and patient report of overall HRQOL, as well as between spouses’ reports of marital quality. Gender was found to moderate the association between patient HRQOL and marital quality; however, gender was not found to moderate the link between patient overall HRQOL and partner’s report of marital quality. These findings demonstrate the importance of the couple relationship to well-being within the context of couples coping with cancer. Implications surrounding the lack of unity in the conceptualization and operationalization of these constructs are discussed, as is the importance of controlling for the influences of gender and social role in future study designs.

Show moreCancer cells possess heightened rates of cell proliferation due to aberrant cellcycle checkpoints. Cannabidiol (CBD) has been shown to down-regulate expression of the inhibitor of DNA-1 (Id-1), a basic helix-loop-helix transcription regulator that controls breast cancer metastasis. CBD is a cannabinoid that does not act efficiently with the known cannabinoid (CB1 and CB2 ) receptors. We studied the link between the ability of CBD to stimulate reactive oxygen species (ROS) production and its ability to inhibit cell viability. The CB1/CB2 receptor partial agonist Δ⁹- Tetrahydrocannabinol could not produce significant amounts of ROS except at a very high concentration demonstrating the unique ability of CBD to generate ROS is not due to CB1 and CB2 activation. Using multiple breast cancer cell lines, we determined the effects of CBD on ROS production were a concentration-dependent and occurred across a majority of breast cancer cell lines evaluated (human and mouse). We also analyzed whether the CB2-receptor selective antagonist SR144528 (SR2) and an ROS scavenger, α-tocopherol (TOC or vitamin E) could reverse the effects of CBD. The CB2 receptor antagonist could only partially reverse the inhibition of cell viability and stimulation of ROS production produced by CBD. TOC however could completely reverse the effects of CBD. To determine whether CBD stimulation of ROS was an effect specifically produced in breast cancer cell lines, we studied this effect in non-transformed human fibroblast cells. CBD produced negligible amount of ROS in non-transformed cells and xii was significantly less effective at inhibiting the viability of the fibroblast, suggesting that CBD must be acting through mechanisms unique to transformed cells. Here, we report that CBD inhibits breast cancer cell viability through efficient stimulation of ROS which is possibly mediated through unique interaction with the cannabinoid system, other than the mechanism of CB1 and CB2 receptor activation.
