Telophase Correction Refines Division Orientation In Stratified Epithelia, K. J. Lough, K. M. Byrd, C. P. Descovich, D. C. Spitzer, A. J. Bergman, Gerard M.J. Beaudoin Iii, L. F. Reichardt, S. E. Williams

Biology Faculty Research

During organogenesis, precise control of spindle orientation balances proliferation and differentiation. In the developing murine epidermis, planar and perpendicular divisions yield symmetric and asymmetric fate outcomes, respectively. Classically, division axis specification involves centrosome migration and spindle rotation, events occurring early in mitosis. Here, we identify a novel orientation mechanism which corrects erroneous anaphase orientations during telophase. The directionality of reorientation correlates with the maintenance or loss of basal contact by the apical daughter. While the scaffolding protein LGN is known to determine initial spindle positioning, we show that LGN also functions during telophase to reorient oblique divisions toward perpendicular. The …

Joule's 19th Century Energy Conservation Meta-Law And The 20th Century Physics (Quantum Mechanics And General Relativity): 21st Century Analysis, Vladik Kreinovich, Olga Kosheleva

Departmental Technical Reports (CS)

Joule's Energy Conservation Law was the first "meta-law": a general principle that all physical equations must satisfy. It has led to many important and useful physical discoveries. However, a recent analysis seems to indicate that this meta-law is inconsistent with other principles -- such as the existence of free will. We show that this conclusion about inconsistency is based on a seemingly reasonable -- but simplified -- analysis of the situation. We also show that a more detailed mathematical and physical analysis of the situation reveals that not only Joule's principle remains true -- it is actually strengthened: it is …

Why Gamma Distribution Of Seismic Inter-Event Times: A Theoretical Explanation, Laxman Bokati, Aaron A. Velasco, Vladik Kreinovich

Departmental Technical Reports (CS)

It is known that the distribution of seismic inter-event times is well described by the Gamma distribution. Recently, this fact has been used to successfully predict major seismic events. In this paper, we explain that the Gamma distribution of seismic inter-event times can be naturally derived from the first principles.

Stock Price Using Domain Specific Lexicons, Zane Turner

Computer Science and Computer Engineering Undergraduate Honors Theses

Sentiment analysis is a broad and expanding field that aims to extract and classifying opinions from textual data. Lexicon-based approaches are based on using a sentiment lexicon, a list of words each mapped to a sentiment score, to rate the sentiment of a text chunk. Our work focuses on predicting stock price change using a sentiment lexicon built from financial conference call logs. We introduce a method to generate a sentiment lexicon based upon an existing probabilistic approach. By using a domain-specific lexicon, we outperform traditional techniques and demonstrate that domain-specific sentiment lexicons provide higher accuracy than generic sentiment lexicons …

Bottlenecks Or Growth Zones? A Study Of The Chirundu And Beitbridge Border Economies, Anna Ngarachu, Christopher Wood, Heinrich Krogman, Elisha Tshuma, Dale Mudenda

Southern African Journal of Policy and Development

Land borders in the Southern African Development Community (SADC) region are critical zones for unlocking regional value chains, trade and economic development. The Beitbridge and Chirundu border posts represent important links in the North–South Corridor. They are vital in both regional development and bilateral initiatives. It is at these borders that many issues related to regional integration intersect. Understanding the major complications that prevent competitive trade and undermine trade facilitation initiatives is, therefore, essential. This policy brief examines the causes of standing time – a major contributor to transport costs in sub-Saharan Africa – and discusses the softer issues such …

2016 Presidential Election - The Winners And Losers In The Health Care Industry, Afua Agyekum, Sharon Finney, Ayishat Omar, Alex P. Tang

Rohrer College of Business Departmental Research

The 2016 presidential election had important implications for the country’s health care policies. In this study, we examine the health care industry stock returns associated with the 2016 presidential campaign. We use both market model and seemingly unrelated regression (SUR) methodologies to estimate abnormal stock returns of each health care sector associated with each event. Our results are robust and mostly consistent with our arguments. The regression analysis further augments our event study results. We find that, during the pre-election period, the Biological Products, Health Insurance, and Major Pharmaceuticals all suffer significantly negative cumulative average abnormal returns (CAARs). The Hospital/Nursing …

Short- And Long-Run Effects Of Early Grades, Luca Facchinello

Research Collection School of Economics

Does early grading affect educational choices? To answer the question, I exploit the staggeredimplementation of a reform which postponed grade assignment in Swedish compulsoryschool. I identify short- and long-term effects of early grading, for students with differentacademic ability and socioeconomic status (SES). When graded early on, high-ability students(especially if high-SES) perform better, and are more likely to choose academic coursesduring compulsory school. Low-ability students react in the opposite way, in particular iflow-SES. While high school attainment increases for high-ability low-SES students, collegeattainment decreases for low-ability low-SES students. None of these effects carry over tothe labor market. This suggests that early …

Tax Policy For The Wider Cryptoverse, Arild B. Doerge

Student Scholarship

The rapid rise of Bitcoin and other “cryptoassets” offers many interesting technological capabilities but also comes with uncertainty and volatility in the markets for these assets. The diversity of types of cryptoassets is increasing rapidly, while public understanding and government policy have generally been slow to take account of this diversity. In regard to taxation policy related to cryptoassets, current IRS guidance merely categorizes cryptoassets as general property. The policy implications of this classification run contrary to fundamental goals of tax policy by inhibiting how people use cryptoassets, making compliance more complex and ambiguous than necessary, and taxing cryptoasset transactions …

Senate Bill 1383 Stinks, Steffani Fausone

Student Scholarship

Climate change is no longer a prediction; it is a reality. Part of the climate change conversation revolves around increased methane emissions, focusing on the agricultural industry as a culprit. To address these concerns, the California legislature recently passed Senate Bill 1383, which aims to reduce methane emissions from one agricultural industry in particular--dairies. This far-fetched bill is the first in the country to attempt to regulate methane from dairy cattle. With so much uncertainty surrounding this bill's effects, this Comment argues that the bill will hurt the dairy industry more than it helps combat climate change. This Comment also …

Beneficial Mutations For Carotenoid Production Identified From Laboratory-Evolved Saccharomyces Cerevisiae, Avinash Godara, Maria Alejandra Gomez Rodriguez, Joshua Weatherston, George Peabody, Hung-Jen Wu, Katy Kao

Faculty Publications

Adaptive laboratory evolution (ALE) is a powerful tool used to increase strain fitness in the presence of environmental stressors. If production and strain fitness can be coupled, ALE can be used to increase product formation. In earlier work, carotenoids hyperproducing mutants were obtained using an ALE strategy. Here, de novo mutations were identified in hyperproducers, and reconstructed mutants were explored to determine the exact impact of each mutation on production and tolerance. A single mutation in YMRCTy1-3 conferred increased carotenoid production, and when combined with other beneficial mutations led to further increased β-carotene production. Findings also suggest that the ALE …

Integrating The Three E’S In Wastewater Treatment, Kirti Maheshkumar Yenkie

Henry M. Rowan College of Engineering Departmental Research

Water is often the most mispriced and misused component in domestic, industrial and agricultural sectors. The rise in world population and industrialization in developing nations has tremendously increased the demand for water and has resulted in the generation of wastewater which is contaminated with dangerous pollutants and unknown contaminants. Furthermore, if the wastewater is not treated properly the toxic pollutants will leach back into the ground ultimately contaminating the groundwater resources. Thus, wastewater treatment, reuse, and safe disposal have become crucial for sustainable existence. In this review, the different aspects involved in designing efficient and sustainable wastewater treatment systems such …

Brownfields Area-Wide Plan: Lower North Delaware Industrial District, Philadelphia, Mahbubur Meenar, Lynn Mandarano, Andrew Goodman, Sally Harrison

School of Earth & Environment Departmental Research

A Brownfields Area-Wide Plan is created for a key portion of Philadelphia’s Lower North Delaware Industrial District. The brownfields challenges in the project are representative of both location-specific factors and issues typical of brownfield redevelopment. One hundred and fifty years of industrial history, from coal to textile or food distribution, cannot help but leave a trace. Locational factors including high vacancy rates, weak market forces, and former industrial uses highlight the classic brownfields challenges of financial barriers, liability issues, and cleanup considerations. The coalescence of these types of difficulties significantly impacts the economic, social, public health, and environmental justice concerns …

Crevasse Initiation And History Within The Mcmurdo Shear Zone, Antarctica, Lynn Kaluzienski, Peter Koons, Ellyn Enderlin, Gordon Hamilton, Zoe Courville, Steven Arcone

Geosciences Faculty Publications and Presentations

While large-scale observations of intensified fracture and rifting can be observed through remote-sensing observations, understanding crevasse initiation may best be achieved with small-scale observations in which crevasses can be directly observed. Here we investigate the kinematic drivers of crevasse initiation in the McMurdo Shear Zone (MSZ), Antarctica. We delineated 420 crevasses from ∼95 km of 400 MHz frequency ground-penetrating radar data and compared these data with kinematic outputs derived from remotely-sensed ice surface velocities to develop a statistical method to estimate crevasse initiation threshold strain rate values. We found the MSZ to be dominated by simple shear and that surface …
