Mathematics and Statistics Faculty Publications

MicroRNAs (miRNAs) are small non-protein-coding RNA molecules that regulate gene expression. Diet and lifestyle factors have been hypothesized to be involved in the regulation of miRNA expression. In this study it was hypothesized that diet and lifestyle factors are associated with miRNA expression. Data from 1,447 cases of colorectal cancer to evaluate 34 diet and lifestyle variables using miRNA expression in normal colorectal mucosa as well as for differential expression between paired carcinoma and normal tissue were used. miRNA data were obtained using an Agilent platform. Multiple comparisons were adjusted for using the false discovery rate q-value. There were 250 …

Et Tu, Android?: Regulating Dangerous And Dishonest Robots, Woodrow Hartzog

Faculty Scholarship

Consumer robots like personal digital assistants, automated cars, robot companions, chore-bots, and personal drones raise common consumer protection issues, such as fraud, privacy, data security, and risks to health, physical safety, and finances. They also raise new consumer protection issues, or at least call into question how existing consumer protection regimes might be applied to such emerging technologies. Yet it is unclear which legal regimes should govern these robots and what consumer protection rules for robots should look like.

This paper argues that the FTC's grant of authority and existing jurisprudence are well-suited for protecting consumers who buy and interact …

Mass Reduction Patterning Of Silicon-On-Oxide–Based Micromirrors, Harris J. Hall, Andrew Green, Sarah Dooley, Jason D. Schmidt, Lavern A. Starman, Derrick Langley, Ronald A. Coutu Jr.

Electrical and Computer Engineering Faculty Research and Publications

It has long been recognized in the design of micromirror-based optical systems that balancing static flatness of the mirror surface through structural design with the system’s mechanical dynamic response is challenging. Although a variety of mass reduction approaches have been presented in the literature to address this performance trade, there has been little quantifiable comparison reported. In this work, different mass reduction approaches, some unique to the work, are quantifiably compared with solid plate thinning in both curvature and mass using commercial finite element simulation of a specific square silicon-on-insulator–based micromirror geometry. Other important considerations for micromirror surfaces, including surface …

Statistical Properties Of Cloud Propagation Over Sumatra During Cpea-I, Aulya Rahayu, Marzuki, Mutya Vonnisa

Makara Journal of Science

Cloud propagation over Sumatra and the surrounding area (10°S-10°N, 70°-120°E) during the Coupling Processes in the Equatorial Atmosphere-I (CPEA-I) campaign (10 April to 9 May 2004) was tracked using brightness temperature (Tb) data from the GOES-9 satellite. The cloud tracking was based on three-dimensional data with a threshold of Tb < 210 K. During the campaign, westward-moving clouds were more dominant than eastward-moving systems, with a ratio of approximately 4:1. This characteristic coincided with the dominant easterly wind aloft. Most clouds propagated with a speed varying between 4 and 35 m/s, with a mean value of 13.7 m/s. If the westward and eastward propagations were separated, the average duration, speed, and span of the westward (eastward) moving clouds are 7.7 (5.8 h), -14.5 (9.8 m/s), and 435.5 (187.1 km), respectively. The characteristics of cloud propagation during the CPEA-I were influenced by environmental factors such as relative humidity, temperature, the vertical movement of air, and wind shear. Such factors interacted with the inactive and active phases of the Madden-Julian Oscillation.

Does Use Of Neutralization Techniques Predict Delinquency And Substance Use Outcomes?, Erin C. Siebert

Clinical Psychology Dissertations

This study was part of a larger research intervention that uses motivational interviewing (MI) as part of an in-school substance abuse intervention in local high schools in the greater Seattle area. Our aim was to test hypothesized relationships between marijuana use, other delinquent behavior, and neutralization techniques used by participants and determine their impact on the effectiveness of an MI-based intervention. Hypotheses were that neutralization technique use would decrease the effectiveness of an MI intervention due to the conflicting cognitive processes of justification and developing discrepancy. Of the 84 participants that completed Intake assessments, 60% were male and identified as …

A Bounded Affinity Theory Of Religion And The Paranormal, Joseph O. Baker, Christoper Bader, F. Carson Mencken

Sociology Faculty Articles and Research

We outline a theory of bounded affinity between religious experiences and beliefs and paranormalism, which emphasizes that religious and paranormal experiences and beliefs share inherent physiological, psychological, and ontological similarities. Despite these parallels, organized religious groups typically delineate a narrow subset of experiences and explanatory frames as acceptable and True, banishing others as either false or demonic. Accordingly, the theory provides a revised definition of the “paranormal” as beliefs and experiences explicitly rejected by science and organized religions. To demonstrate the utility of the theory, we show that, after controlling for levels of conventional religious practice, there is a strong, …

PSR J1957+2516 is likely a redback pulsar, with a ∼0.1 M⊙ companion and possible eclipses that last ∼10% of the orbit. The position of PSR J1957+2516 is also coincident with a near-infrared source. All five MSPs are distant …

An Orphanage In Mexico: Four United Nations' Human Rights Of Children And Wolins' Prerequisites For Efficient Group Care Through The View Of The Manager And Staff, Lucia Beatriz Quesnel Galván

Dissertations and Theses

In Mexico there are officially 1.8 million orphaned children, without counting non-orphaned children deprived of family, who also need care; of these, only 657,000 are living in 703 orphanages. Mexico's government invests less than 2% of its budget toward protection of children. There is a lack of substantive research or official assessment of orphanages. According to the scant research found, the children's human rights most frequently violated in Mexican orphanages are the rights to nutrition and health care, to be protected from further victimization, to free expression and participation, and to not be exploited. This study was carried out through …

The “Acronet Paradigm”, An “Open Hardware” Project, Adriano Fedi, Daniele Ferrari, Marco Lima, Fabio Pintus, Cosimo Versace, Giorgio Boni

Open Water Journal

For the monitoring of hydrometeorological variables, and more generally, for decision support systems, the instrumental in-situ measurement is crucial.

Referring to professional micrometeorological stations, there is a problem represented by the high costs of measures.

The high cost can be substantially related to the quality of the materials, to the array of industrial production processes and to the costs of skilled workers, needed for the installation and for the maintenance of the equipment.

A further problem in the development of such measuring networks is represented by "closed" products which, for structural layouts, data management and communications, are almost always referred …

H2pl: A New Open Source Library For Hydrological Modeling, Khodayar Abdollahi, Okke Batelaan, Marijke Huysmans

Open Water Journal

Due to spatial and temporal variation of hydrologic processes, development of distributed hydrological models remained a difficult task over the last decades. As a consequence application of Geographic Information Systems (GIS) has become a useful and popular tool not only for hydrology but also in many different fields of science. On the other hand, literature emphasizes that hydrological modelers use GIS blindly but should take the advantage of advances in computing technology. This issue generates a demand for development of hydrological frameworks to conceptualize time and space models which targets hydrological modeling specifically.

This study presents the development of an …

“The Battle-Fortune Of Marshal Hindenburg Is Not Bound Up With The Possession Of A Hill”: The Germans And Vimy Ridge, April 1917, Holger Herwig

Canadian Military History

On 9 April 1917 four Canadian divisions and one British division of 170,000 men broke through the “Vimy Group” of German Sixth Army of some 40,000 men. By late afternoon, the Germans had been driven off the Ridge. That day, as Brigadier-General Alexander Ross famously put it, constituted “the birth of a nation.” Rivers on ink have been spilled in the Canadians’ actions that day, but little attention has been paid to “the other side of the hill.” Which German units defended the Ridge? What was the quality of their leadership? Why did the defence collapse so quickly? Why did …

Finite Element Simulation And Additive Manufacturing Of Stiffness-Matched Niti Fixation Hardware For Mandibular Reconstruction Surgery, Ahmadreza Jahadakbar, Narges Shayesteh Moghaddam, Amirhesam Amerinatanzi, David Dean, Haluk E. Karaca, Mohammad Elahinia

Mechanical Engineering Faculty Publications

Process parameters and post-processing heat treatment techniques have been developed to produce both shape memory and superelastic NiTi using Additive Manufacturing. By introducing engineered porosity, the stiffness of NiTi can be tuned to the level closely matching cortical bone. Using additively manufactured porous superelastic NiTi, we have proposed the use of patient-specific, stiffness-matched fixation hardware, for mandible skeletal reconstructive surgery. Currently, Ti-6Al-4V is the most commonly used material for skeletal fixation devices. Although this material offers more than sufficient strength for immobilization during the bone healing process, the high stiffness of Ti-6Al-4V implants can cause stress shielding. In this paper, …
