title: An Analysis of Pollution in the York River Watershed
Creators: name: McConnell, Taylor H
Publisher: name: George Mason University
Year: 2020
Subjects: subject: Eutrophication
subject: Chesapeake Bay
subject: Dissolved Oxygen
subject: Nitrogen
subject: Phosphorus
subject: York River

description: This study addresses the lack of a proper mapping assessment of field-level pollution sources for the implementation of pollution management practices. Phosphorus and nitrogen entering streams and rivers contribute to eutrophication as well as greenhouse gas (GHG) production in the York River. Not only do nitrogen and phosphorus enter the river, but manmade chemicals, such as polychlorinated biphenyls (PCBs) do as well. An environmental analysis of the potential contribution of the reduction of nutrients from nonpoint and point sources of pollution to the Chesapeake Bay originating in the York River, Virginia was conducted. The research focuses on three objectives each in their own chapter: 1) What are the main sources of water pollutants in the York River?; 2) How has the water pollution of the York river changed between 1986 and 2013?; and 3) What is the rate of algae bloom expansion and the increase in invasive algae species in the York River? This study finds that the York River has rapidly increased in its pollution over the past twenty-seven years and finds evidence of large amounts algae blooms and loss of animal and fish species in the surrounding area. The study is inconclusive about urban development. Future work in the increase of human development along the river needs to be conducted in order to isolate causes and contributions to the rapid increase of pollution into the York River.

description: This thesis explores the use of ayahuasca, a hallucinogenic plant concoction from the Amazon, by people from the English speaking world. This thesis argues that there is no “original” or “typical” use of ayahuasca; it is a dynamic practice that has undergone massive change. In order to show this change, this thesis describes the different roles that shamans have had as a result of colonialism and modernization. Fieldwork was carried out at a healing center in the Peruvian Amazon. The motivations of informants and the effects ayahuasca had on them are compared with previous research on non-native ayahuasca use. The motivations of non-natives for taking ayahuasca are different from native motivations. The two main reasons are a desire for an end to alienation and a resolution of emotional trauma. Nearly all participants reported positive experiences from taking ayahuasca. The ayahuasca intoxication produces a liminal period, in which participants are able to reflect upon the issues affecting them.

description: Fragmentation of expensive resources, e.g., spectrum for wireless services, between providers can introduce inefficiencies in resource utilisation and worsen overall system performance. In such cases, resource pooling between independent service providers can be used to improve performance. However, for providers to agree to pool their resources, the arrangement has to be mutually beneficial. The traditional notion of resource pooling, which implies complete sharing, need not have this property. For example, under full pooling, one of the providers may be worse off and hence have no incentive to participate. In this paper, we propose partial resource sharing models as a generalization of full pooling, which can be configured to be beneficial to all participants. We formally define and analyze two partial sharing models between two service providers, each of which is an Erlang-B loss system with the blocking probabilities as the performance measure. We show that there always exist partial sharing configurations that are beneficial to both providers, irrespective of the load and the number of circuits of each of the providers. A key result is that the Pareto frontier has at least one of the providers sharing all its resources with the other. Furthermore, full pooling may not lie inside this Pareto set. The choice of the sharing configurations within the Pareto set is formalized based on bargaining theory. Finally, large system approximations of the blocking probabilities in the quality-efficiency-driven regime are presented.

description: We use the known values of the two loop Wilson coefficients and the three loop anomalous dimension matrix $γ(n)$ to perform a next-to-next-to leading order (NNLO) calculation of $ep$ deep inelastic scattering. Because $γ(n)$ is only known for a few values of $n$, the method of average reconstruction has to be used, which leaves 102 effective experimental points, for 12 parameters: the QCD mass $Λ$, and 11 initial values for the moments of the structure functions. The data points spread in the range of momenta $2.5 GeV^2\leq Q^2\leq 230 GeV^2$. The chi/dof decreases substantially when going from LO to NLO, and also from NLO to NNLO (although only a little now) to $χ/dof=79.2/(102-12)$. The favoured value of $Λ$ is $$Λ(n_f=4,3 {\rm loop})=282.7\pm35.1 MeV,$$ corresponding to the value of the coupling at the Z mass of $$α^{(\rm 3 loop)}_s(M_Z^2)=0.1172\pm0.0024. $$ The calculation, which constitutes a very precise test of QCD, includes target mass corrections; the error takes into account experimental errors and higher twist effects among other estimated theoretical errors.

Light chemical elements in stars: mysteries and unsolved problems

Publisher: name: arXiv
Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The first eight elements of the periodic table are discussed: H, He, Li, Be, B, C, N, and O. They are referred to as key elements, given their important role in stellar evolution. It is noteworthy that all of them were initially synthesized in the Big Bang. The primordial abundances of these elements calculated using the Standard Model of the Big Bang (SMBB) are presented in this review. The good agreement between the SMBB and observations of the primordial abundances of the isotopes of hydrogen and helium, D, 3He, and 4He, is noted, but there is a difference of ~0.5 dex for lithium (the isotope 7Li) between the SMBB and observations of old stars in the galactic halo that has not yet been explained. The abundances of light elements in stellar atmospheres depends on the initial rotation velocity, so the typical rotation velocities of young Main Sequence (MS) stars are examined. Since the data on the adundances of light elements in stars are very extensive, the main emphasis in this review is on several unsolved problems.

title: Use of Unapproved Medical Countermeasures During Public Health Emergencies: Comparing the United States and South Korea
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2021

description: Biodefense includes the implementation of various activities related to biological warfare, bioterrorism, biosurveillance, emergency preparedness, and medical countermeasure (MCM) development. According to the narratives of historical institutionalism (HI), biodefense is an institution that has transformed by following a pattern of punctuated evolution due to exogenous shocks. However, other scholars criticize the meso-level analysis of the HI school of thought and emphasize the role of agency (endogenous factors) in institutional changes. This dissertation provides domestic-level, detailed accounts of how the biodefense institutions of the United States and South Korea have evolved by employing Thomas Birkland’s Event-Related Policy Change Model. According to Birkland’s model, the Emergency Use Authorization (EUA) policy, one of the representative biodefense policies, was legislated in the United States based on the lessons learned from Amerithrax in 2001, while Korea’s policy was based on the lessons learned from the Middle East Respiratory Syndrome (MERS) outbreak in 2015. Due to these divergent lessons arising from different focusing events (critical junctures), the US EUA stresses homeland security policy and follows an evolutionary path of strengthening post-exposure prophylaxis (PEP) missions. On the other hand, the Korean EUA pursues disease containment missions and follows an evolutionary path of strengthening diagnostic capabilities. Finally, the different features of the EUA policies in the two countries are the result of different testing outcomes during the early phase of the COVID-19 pandemic. This dissertation examines why the homeland security-centric US EUA struggled to integrate with other public health systems to support large-scale testing missions. Furthermore, policy recommendations for the United States, South Korea, and other countries pursuing an EUA policy are proposed.

The effect of viscosity on the entropy production is studied in ideal as well as in viscous hydrodynamics with and without supercooling. It is found that the excess entropy produced due to supercooling depends weakly on viscosity.

description: It’s difficult to answer this question. Is it philosophical, is it economical, sociological, even ethical or religious? This topic is a really actual challenge in our Information Society. Information Science tries to give an answer exactly to this question. Our world of work and life has to manage actually a too great amount of Information and Data. This scientific branch has the goal to come over this great challenge in a humanlike, scientific manner. Science should not only bring detailed special knowledge – like Old Greek Sophists – it should bring precious, mental, philosophical orientations. The generation of Scientists, who has been growing up with the Computer and realised the broad influences of modern IT (Information Technology) to our whole society is now, about 70 years after finding first Computers, obliged to reorganise some terms in our society. We recognise that our children and grandchildren have no more experience of a life without a Computer. We called them - new - the Digital Generation. Information Science was created parallel to Informatics about 1968, as an own branch of research, interested in all what was changed by the Computer. The fascination of the technically new facts has given her leading role to general new challenges and followings for our whole society. These Scientists seek necessary results, because they worked responsibly in leading positions in Computer Science since their starting. Our society needs trust in future happenings. It can come worse – but it shouldn`t do so. This article tries to keep economic happenings in Authors eye. Economy, Ecology and World of Work are in focus. Geo-political findings will be involved. Great, orienting guidelines will be researched and written down. Personal, human borders by being only one researcher can´t be negotiated – of course.

description: Interaction / collision of two concentric spherical thin-shells of linear fluid resulting in collapse has been considered recently. We show that addition of finely tuned electric charges on the shells apart from the cosmological constant serves to delay the collapse indefinitely, yielding an ever colliding system of two concentric fluid shells. Given the finely tuned charges this provides an example of a perpetual two-body motion in general relativity.

Publisher: name: George Mason University
Year: 2023

description: K-means clustering is an algorithm used for creating groups of similar data points. In this study, we aim to apply a K-means model to song data to accurately group alike songs. To accomplish this, we used Python’s pandas module for data processing and its scikit-learn Module for clustering. Specifically, we employed the “KMeans” class from the clustering library. Our findings, such as scoring methods, supported the model’s strength, despite the correlation matrix between the variables displaying many weak correlations (see Figure 2). This suggests clustering’s ability to compensate for lacking correlation.

description: After a brief history of heavy quarks, I will discuss charm, bottom, and top quarks in turn. For each one, I discuss its first observation, and then what we have learned about production, hadronization, and decays - and what these have taught us about the underlying physics. I will also point out remaining open issues. For this series of lectures, the charm quark will be emphasized. It is the first of the heavy quarks, and its study is where many of the techniques and issues first appeared. Only very brief mention is made of CP violation in the bottom-quark system since that topic is the subject of a separate series of lectures by Gabriel Lopez. As the three quarks are reviewed, a pattern of techniques and lessons emerges. These are identified, and then briefly considered in the context of anticipated physics signals of the future; e.g., for Higgs and SUSY particles.

description: Es ist schwer, diese Frage einzuordnen. Ist sie philosophisch, ist sie ökonomisch, soziologisch, sogar ethisch oder religiös? Dieses Thema ist eine echt aktuelle Herausforderung in unserer Informationsgesellschaft. Die Informationswissenschaft befasst sich genau damit, weil sie unsere Arbeits- und Lebenswelt im Umgang mit der Unmenge an neuen Informationen erforschen und menschengerechter ermöglichen will. Jede verantwortungsvolle Wissenschaft sollte nicht nur Detailwissen im Sinne der Altgriechischen Sophisten vermitteln, sondern auch wertvolle, geistige, philosophische Orientierungen geben können. Die Generation von Wissenschaftlern, die mit dem Computer erwachsen geworden ist und die großen Auswirkungen der modernen IT(Informationstechnologie) auf unsere Gesellschaft miterlebt hat, ist heute, etwa 70 Jahre nach dem ersten Computer, dabei, die gesamte Gesellschaft umzuorganisieren. Wir erleben unsere Kinder und Enkelkinder, die erstmals keine Erfahrungen mehr haben, wie man ohne Computer und Informationstechnologie (IT) leben kann. Wir sprechen von einer neuen Generation, der Digitalen Generation. Informationswissenschaft ist parallel zu Informatik etwa um 1968 entstanden, ein eigener Forschungszweig, an allem interessiert, was der Computer bewirkt hat. Die Faszination des technisch Neuen ist den Aufgaben aus den vorhandenen Gesamtfolgen für unsere Gesellschaft gewichen. Diese Wissenschaftler fühlen sich zu Ergebnissen verpflichtet, weil sie dieses Informationszeitalter seit Beginn und oft in führenden Stellen mitgestaltet haben. Was unserer Informationsgesellschaft fehlt, ist das Vertrauen in eine positive Zukunft, die zwar schlechter werden kann - aber eben nicht soll. Diese Arbeit, will speziell die wirtschaftlichen Auswirkungen in der Ökonomie, Ökologie und Arbeitswelt ins Auge fassen. Auch geopolitische Erkenntnisse sollen bedacht werden. Große, orientierende Richtlinien sollen erforscht und aufgeschrieben werden – persönliche, menschliche Grenzen des Autors können selbstverständlich nicht negiert werden.

Faster individual discrete logarithms in finite fields of composite extension degree

Publisher: name: arXiv
Year: 2018
Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Computing discrete logarithms in finite fields is a main concern in cryptography. The best algorithms in large and medium characteristic fields (e.g., {GF}$(p^2)$, {GF}$(p^{12})$) are the Number Field Sieve and its variants (special, high-degree, tower). The best algorithms in small characteristic finite fields (e.g., {GF}$(3^{6 \cdot 509})$) are the Function Field Sieve, Joux's algorithm, and the quasipolynomial-time algorithm. The last step of this family of algorithms is the individual logarithm computation. It computes a smooth decomposition of a given target in two phases: an initial splitting, then a descent tree. While new improvements have been made to reduce the complexity of the dominating relation collection and linear algebra steps, resulting in a smaller factor basis (database of known logarithms of small elements), the last step remains at the same level of difficulty. Indeed, we have to find a smooth decomposition of a typically large element in the finite field. This work improves the initial splitting phase and applies to any nonprime finite field. It is very efficient when the extension degree is composite. It exploits the proper subfields, resulting in a much more smooth decomposition of the target. This leads to a new trade-off between the initial splitting step and the descent step in small characteristic. Moreover it reduces the width and the height of the subsequent descent tree.

description: This thesis presents an experimental investigation of the Narrow Gap Improved Electroslag (ESW-NG) welding method when applied on HPS 70W high-performance steel and the associated tests required for qualification of the welding method under the American Welding Society D1.5:2010 (AWS) bridge welding code. The welding process is studied in detail through testing of two weld qualification plates and the base metal. Tension testing, toughness testing and hardness testing of specimens with various geometries and orientations within the two plates and the base metal were performed, in addition to the tests required for weld qualification. The testing methods and specimens used are thoroughly described and their significance is explained. The experimental results achieved the objective of determining and characterizing the mechanical properties of HPS 70W high-performance steel when welded with ESW-NG. However, the research revealed that ESW-NG cannot be pre-qualified for HPS 70W per the AWS code at this time due to the failure of the all-weld tension specimens.

description: An elegant and efficient method has been outlined for the synthesis of novel 5-amino-4-[4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl]-3-arylthiophene-2-carbonitriles employing a one-pot four-component reaction of various aldehydes, 2-[4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl]acetonitrile, malononitrile and molecular sulfur independently in the presence of L-proline as a catalyst, under green reaction conditions. In an alternative approach, initially, the Knoevenagel condensation of these various aldehydes has been carried out with active methylene compounds malononitrile or 2-[4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl]acetonitrile to obtain the corresponding condensed compounds. These compounds then further subjected to a one-pot three-component Gewald reaction with molecular sulfur using sodium bicarbonate as a simple and inexpensive catalyst to obtain the target compounds. The effect of solvent and catalyst on these reactions has been screened to obtain the optimal conditions. The advantages of this protocol are the use of mild reaction conditions at ambient temperature, environmental friendliness, good yields in faster reaction times, convenient operation procedures, and broad substrate scope.

description: The lightest scalar and pseudoscalar nonets are discussed within the framework of the broken U3$\times$U3 linear sigma model, and it is shown that already at the tree level this model works remarkably well predicting scalar masses and couplings not far from present experimental values, when all parameters are fixed from the pseudoscalar masses and decay constants. It is argued that this strongly suggests that the light and very broad $σ$ resonance exists near 500 MeV.

description: It was Christmas Day, 1993. My dad and I had been talking about it for a month and the day was finally here. Batman: Mask of the Phantasm had finally come to theatres. I was a huge fan of its predecessor television series Batman: The Animated Series, so I was doubly excited to see it on the big screen. I’d seen the trailers multiple times as they played during my cartoons, and I’d studied the ads in my comics for what felt like an eternity. All of the waiting eventually paid off. The movie received great reviews, was successful at the box office, and most importantly, my dad and I loved it. I remember the familiarity the movie created because the animation style and all of the voice actors were the same from the TV series; it immediately felt right. No context was needed. No backstory. I knew everything that I needed to know because I’d seen every episode of the show. Little did I realize that this was my first real experience of transmedia storytelling.

description: This dissertation studies an online community (“subreddit”) related to the so-called “Intellectual Dark Web” (IDW) on the social media platform Reddit to understand the social and epistemological significance of the IDW within the social setting of what Jodi Dean calls “communicative capitalism.” Using deep neural language models, a novel topic modeling algorithm (BERTopic), and qualitative content analysis, this research offers a discursive mapping of the social, cultural, and political issues structuring discourse on the IDW subreddit. Across a sample of more than 400,000 Reddit comments, my exploratory topic model discovers 114 topics nested within 10 topical categories: Culture Wars; Governance & Political Institutions; IDW-Related; Platforms, Media & Information; Political Economy; Political Ideologies; Race & Ethnicity; Science, Knowledge & Epistemology; and Sex & Gender. Emergent from these ten categories are three overarching meta-themes: Sensemaking in Communicative Capitalism; Identity, Ideologies, and Social Justice; and Crises of Civilization. Through my mixed methods analysis, I argue that the chief social significance of the IDW is based in how, through its discourses, criticisms, and “sensemaking” practices, it provides a sense of reality to its constituents amidst the profound epistemic pessimism and social distrust foundational to communicative capitalism.

description: Standard Reaction-Diffusion (RD) systems are characterized by infinite velocities and no persistence in the movement of individuals, two conditions that are violated when considering living organisms. Here we consider a discrete particle model in which individuals move following a persistent random walk with finite speed and grow with logistic dynamics. We show that when the number of individuals is very large, the individual-based model is well described by the continuous Reactive Cattaneo Equation (RCE), but for smaller values of the carrying capacity important finite-population effects arise. The effects of fluctuations on the propagation speed are investigated both considering the RCE with a cutoff in the reaction term and by means of numerical simulations of the individual-based model. Finally, a more general Lévy walk process for the transport of individuals is examined and an expression for the front speed of the resulting traveling wave is proposed.

Current fluctuations in a single tunnel junction

description: We study noise spectra of currents through a tunnel junction in weak tunneling limit. We introduce effective capacitance to take into account the interaction effect and explicitly incorporate the electromagnetic environment of the junction into the formulation. We study the effect of charging energy and macroscopic environment on noise spectra. We calculate current fluctuations at tunneling barrier and fluctuations measured at leads. It is shown that two fluctuations have different noise spectra and the relation between them is nontrivial. We provide an explanation for the origin of the difference. Experimental implications are discussed.

title: The Effects of Visual Cues and Interstimulus Interval on Error Rates in Auditory Localization and Detection
Creators: name: Coyne, Joseph Thomas
Publisher: name: Old Dominion University
Year: 2002

description: Auditory localization is an increasingly important topic as the technology for audio displays is becoming more available. However, few studies examine the effects of multiple simultaneous distracters on auditory detection and localization performance. Previous research has found that detection and localization performance significantly drops as the number of distracters increases; however, it is not clear what causes these errors. Six loudspeakers were arranged in a semicircle, and participants either had to localize an auditory stimulus or detect an auditory stimulus among multiple distracters. Participants' response time and accuracy were recorded for each trial. The number of detection errors was equivalent between the localization and detection groups, although the localization group made significantly more errors overall. Similar to previous research, the number of errors significantly increased as the number of active speakers increased. The use of visual cues was found to benefit the localization group but did not significantly affect performance in the detection group. The present study found that a longer interstimulus interval improved accuracy in the localization group only when cues were present. Interstimulus intervals had no effect in the detection task. These findings provide insight into the complex nature of the auditory search task.
Bounds on the CP Asymmetry in $b\to sγ$ Decays

description: We have measured the CP asymmetry A_CP = [BF(b -> s gamma) - BF(bbar -> sbar gamma)]/ [BF(b -> s gamma) + BF(bbar -> sbar gamma)] to be A_CP = (-0.079 +/- 0.108 +/- 0.022)(1.0 +/- 0.030), implying that, at 90% confidence level, A_CP lies between -0.27 and +0.10. These limits rule out some extreme non-Standard Model predictions, but are consistent with most, as well as with the Standard Model.

description: The associative operad is the quotient of the magmatic operad by the operad congruence identifying the two binary trees of degree $2$. We introduce here a generalization of the associative operad depending on a nonnegative integer $d$, called $d$-comb associative operad, as the quotient of the magmatic operad by the operad congruence identifying the left and the right comb binary trees of degree $d$. We study the case $d = 3$ and provide an orientation of its space of relations by using rewrite systems on trees and the Buchberger algorithm for operads to obtain a convergent rewrite system.

Diffractive Production at Collider Energies and Factorization

Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The most important consequence of Pomeron being a pole is the factorization property. However, due to Pomeron intercept being greater than 1, the extrapolated single diffraction dissociation cross section based on a classical triple-Pomeron formula is too large leading to a potential unitarity violation at Tevatron energies, which has been referred to as "Dino's paradox". We review our resolution which involves a proper implementation of final-state screening correction, with "flavoring" for Pomeron as the primary dynamical mechanism for setting the relevant energy scale. In this approach, factorization remains intact, and unambiguous predictions for double Pomeron exchange, doubly diffraction dissociation, etc., both at Tevatron and at LHC energies, can be made.

description: Spatial (horizontal) price transmission analysis provides specific evidence as to the competitiveness of markets, the effectiveness of arbitrage and the pricing efficiency. The paper investigates spatial price transmission and market integration in the Russian Federal Districts using monthly milk prices within the period 2000-2018. Using Hansen-Seo technique, threshold effects have been found and threshold vector error correction model with two regimes has been estimated for three markets. Market integration analysis revealed a long-run relationship for all the price pairs in the milk markets. The linear VECM analysis showed a rather low degree of integration, especially for the Southern Federal District milk market. Compared to VECM, the TVECM estimation provided different findings depending on regimes and markets.

description: The conversion of African-American men to Islam , has been taking place for many generations. But why are African-Americans, now experiencing a more assimilated position within American society with the second-term presidency of President Barack Obama, choosing Islam, increasingly marginalized in American culture? This thesis not only explores the motivation for this conversion, but also how it affects the converts’ identity and how they place themselves within the broader American landscape. Interviews with African-American men demonstrate a mixture of spiritual fulfillment, historical acknowledgement of Islam and a renewed sense of personal, as well as, group identity within the United States.
