  • Authors: Pantazatos, Dennis Peter (2006)

  • Three dimensional structure determination and analysis of proteins is necessary for the understanding of how proteins participate in human disease, and are critical for the effective design of therapeutics for clinically important targets. Current efforts for determining protein structures are centered on novel high-throughput (HT) approaches. These include high throughput (HT) crystallization efforts and global structure prediction efforts monitored through the Critical Assessment of Structure Prediction (CASP) experiments where progress has been incremental at best. Protein structure analysis of conformational changes and protein-proteins interactions can be monitored by biophysica...

  • Authors: Marks, Tim Kalman (2006)

  • We present a generative graphical model and stochastic filtering algorithm for simulta¬neous tracking of 3D rigid and nonrigid motion, object texture, and background texture from single-camera video. The inference procedure takes advantage of the conditionally Gaussian nature of the model using Rao-Blackwellized particle filtering, which involves Monte Carlo sampling of the nonlinear component of the process and exact filtering of the linear Gaussian component. The smoothness of image sequences in time and space is exploited using Gauss-Newton optimization and Laplace’s method to generate proposal distributions for importance sampling. Our system encompasses an entire continuum from ...

  • Events occur in every aspect of our lives. An unexpectedly large number of events occurring within some certain measurement (e.g. within some time du-ration or a spatial region) is called a burst, suggesting unusual behaviors or activities. Bursts come up in many natural and social processes. It is a challenging task to monitor the occurrence of bursts whose lasting duration is unknown in a fast data stream environment. This work describes efficient data structures and algorithms for high performance burst detection under different settings. Our view is that bursts, as unusual phenomena, constitute a useful preliminary primitive in a knowledge discovery hierarchy. Our intent is to bu...

  • Authors: Nguyen, Ngoc Tu. (2008)

  • Fault detection and diagnosis in rotating machines have been used widely in commercial systems over the past few decades. Numerous works on machine conditions have been implemented with the aid of the MCSA (Motor Current Signature Analysis) method, the vibration-based methods, etc. The purpose of these methods is to detect and diagnose faults in an early stage and therefore allow contingency plans to be put into place before the problems worsen. The dynamic and vibratory behaviours of the machine, such as vibration, sound, and temperature… are affected if the running condition is changed. The behaviours can be useful indicators to detect problems within the machine as they vary abnorm...

  • 23. Finding Great Ideas in Emerging Markets.pdf.jpg
  • Article

  • Authors: Washburn, Nathan; Hunsaker, B.Tom (2011-09)

  • Many companies in mature markets assume that the only reason to enter emerging markets is to pursue new customers. They haven’t yet realized the potential for innovation in developing countries _ though a few visionary multinationals are tapping that potential for much – needed ideas in products and service. General electric, with its portable ultrasound technology, and intel, with its inexpensive classmate PC, are two examples. Other companies see the potential but find it hugely difficult to develop ideas in unfamiliar settings, much less turn them into global businesses: C_Level executives may resist disruptive concepts, or their organizations may lack the processes necessary for a...

  • Anaerobic digesters have been used for treatment of various wastewaters. Systems are usually operated at mesophilic (35°C) temperatures and long hydraulic retention times (HRTs) (> 20 days). Pathogen reduction during anaerobic digestion is mainly correlated with operating temperature and HRT. Higher temperatures and longer HRTs result in increased rates of pathogen decimation. Previous studies show that a novel fixed-film anaerobic digester, operated at a low HRT (< 3 days) and ambient temperature (< 28°C) treating flushed dairy manure wastewater, achieved significant reductions of indicator and pathogenic bacteria. Thus, we sought to determine factors that contributed to indicator...

  • 9. The Flexible Teacher.pdf.jpg
  • Article

  • Authors: Christenbury, Leila (2010-12)

  • The article discusses the characteristics of effective educators and the central role strong teaching plays in student success. The author examines key aspects of engaging teaching methods such as making the educational needs of students a top priority, making subjects interesting and engaging for students, and allowing teachers to employ a variety of strategies to reach students with different learning styles. An explanation of teacher workshops relating to developing effective teaching techniques, an examination of public opinion regarding the importance of teachers, and an evaluation of educational legislation such as the 2001 No Child Left Behind Act are also included.

  • Article

  • Authors: Glenn, David (2011-04)

  • The article discusses business education at U.S. universities and examines reasons why statistics regarding the amount of time students spend studying and preparing for courses show that undergraduate business students are generally disengaged. It explores the problem solving and critical thinking skills that employers seek when hiring college graduates and describes the business education structure at schools such as Radford University, Ohio University, and the University of Virginia. Other topics include the book "Academically Adrift: Limited Learning on College Campuses" by Richard Arum and Josipa Roska, the Collegiate Learning Assessment (CLA) national standardized essay test, and...

  • Authors: Nguyễn, Thị Hiền [Người dịch]; Verdon, Michel (2010)

  • Gần đây,một số nhà nhân học theo trường phái tân Boas (neo-Boasian anthropologists) mô tả Boas như một nhà nhân học với cảm nhận sâu sắc về lịch sử,về cá nhân và chủ thể.Nghiên cứu sâu thực hành dân tộc học của Boas chứ không tập trung vào những tuyên bố lý thuyết và khái quát của ông, trước hết, tôi thấy ông là một nhà dân tộc học quan tâm đến nguyên tửluận (trái ngược với chính thể luận),và một sự hội tụ sâu sắc giữa nghiên cứu các vấn đề tiểu tiết này và lịch sử tự nhiên theo kiểu Linnaean.Theo diễn giải của Foucault Jacob về lịch sửtự nhiên, điều này có nghĩa là nghiên cứu hiện tượng văn hóa xã hội thông qua những biểu hiện bên ngoài, và làm mất đi tính lịch sử, thậm chí cả những...

  • Ubiquitin is a covalent protein tag that alters the stability or behavior of a growing list of proteins. Covalent attachment of ubiquitin to target proteins occurs through a cascade of enzymes: Ubiquitin is charged by a ubiquitin-activating enzyme (E1), and transferred to a ubiquitin-conjugating enzyme (E2). Then, transfer of ubiquitin from E2 to a target protein is brokered by a ubiquitin ligase (E3). A critical aspect of E3 function is the selection of a particular E2 to accomplish ubiquitination of a substrate. We examined the requirements for correct E2-E3 specificity in the RING- H2 ubiquitin ligase Hrd1p, an ER-localized protein known to use primarily Ubc7p for its function. ...

  • The human cytomegalovirus (HCMV) IE2 86 kDa protein is an essential viral regulatory factor that has been shown in transient transfection and in vitro assays to transactivate early viral promoters and to interact with many viral and celular proteins. To understand the functions provided by this protein in the HCMV-infected cel, we have constructed and characterized a family of recombinant viruses containing changes to the IE2 gene and other parts of the HCMV major immediate early (IE) region. The study of these HCMV mutants has alowed us to confirm that several of the predicted functions of IE2 86 are relevant in the virus-infected cel and has identified new functions for the protein...

  • Polypropylene (PP) and polystyrene (PS) nanolayer films were prepared. The crystal structure of extremely thin PP layers confined between PS layers was studied. Changes in structure were observed as the PP layer thickness decreased to the nanoscale. A dispersion of isotactic polypropylene (PP) particles was produced by interfacial-driven breakup of PP nanolayers. Particle size analysis indicated that breakup of PP microlayers produced a bimodal particle size distribution. A population of submicron particles formed due to the Rayleigh instability, and a second population of large particles formed by relaxation. Breakup of 12 nm layers resulted in primarily submicron particles, which c...

  • Due to complexity of biomedical problems, adaptive and intelligent knowledge discovery and data mining systems are highly needed to help humans to understand the inherent mechanism of diseases. For biomedical classification problems, typically it is impossible to build a perfect classifier with 100% prediction accuracy. Hence a more realistic target is to build an effective Decision Support System (DSS). In this dissertation, a novel adaptive Fuzzy Association Rules (FARs) mining algorithm, named FARM-DS, is proposed to build such a DSS for binary classification problems in the biomedical domain. Empirical studies show that FARM-DS is competitive to state-of-the-art classifiers in te...

  • A complex system is an artificial system that cannot be modeled analytically or optimized in an effective manner, usually because it possesses the following properties: (1) the system can only be modeled as a simulation, (2) the size of the problem is untenable, so that even if the system could be modeled analytically, it would be impractical to solve it exactly, (3) necessary information required for problem solving is distributed in nature. This thesis presents methods for modeling and optimizing systems with the above challenging properties. We first discuss the important modeling decision of whether to include stochasticity. By employing a real-world case study, we show that a st...
