Charged Black Hole Mergers: Orbit Circularisation and Chirp Mass Bias

description: We consider the inspiral of black holes carrying U(1) charge that is not electromagnetic, but corresponds to some dark sector. In the weak-field, low-velocity regime, the components follow Keplerian orbits. We investigate how the orbital parameters evolve for dipole-dominated emission and find that the orbit quickly circularises, though not as efficiently as for a gravitationally dominated emission. We then regard circular orbits, and look for modifications in the gravitational waveform from the components carrying small charges. Taking this into account we populate the waveform with simplified LIGO noise and put it through a matched filtering procedure where the template bank only consists of uncharged templates, focusing on the charges' effect on the chirp mass estimation. We find a consistent overestimation of the `generalised' chirp mass, and a possible over- and underestimation of the actual chirp mass. Finally, we briefly consider the effect of such charges on hyperbolic encounters, finding again a bias arising from interpreting the generalised chirp mass as the actual chirp mass.

description: We establish natural criteria under which normally iterable premice are iterable for stacks of normal trees. Let $Ω$ be a regular uncountable cardinal. Let $m<ω$ and $M$ be an $m$-sound premouse and $Σ$ be an $(m,Ω+1)$-iteration strategy for $M$ (roughly, a normal $(Ω+1)$-strategy). We define a natural condensation property for iteration strategies, "inflation condensation". We show that if $Σ$ has inflation condensation then $M$ is $(m,Ω,Ω+1)^*$-iterable (roughly, $M$ is iterable for length $\leqΩ$ stacks of normal trees each of length ${<Ω}$), and moreover, we define a specific such strategy $Σ^{\mathrm{st}}$ and a reduction of stacks via $Σ^{\mathrm{st}}$ to normal trees via $Σ$. If $Σ$ has the Dodd-Jensen property and $\mathrm{card}(M)<Ω$ then $Σ$ has inflation condensation. We also apply some of the techniques developed to prove that if $Σ$ has strong hull condensation (introduced independently by John Steel) and $G$ is $V$-generic for an $Ω$-cc forcing, then $Σ$ extends to an $(m,Ω+1)$-strategy $Σ^+$ for $M$ with strong hull condensation, in the sense of $V[G]$. Moreover, this extension is unique. We deduce that if $G$ is $V$-generic for a ccc forcing then $V$ and $V[G]$ have the same $ω$-sound, $(ω,Ω+1)$-iterable premice which project to $ω$.

description: We calculate the first four cumulants of the integrated current of the one dimensional symmetric simple exclusion process of $N$ sites with open boundary conditions. For large system size $N$, the generating function of the integrated current depends on the densities $ρ_a$ and $ρ_b$ of the two reservoirs and on the fugacity $z$, the parameter conjugated to the integrated current, through a single parameter. Based on our expressions for these first four cumulants, we make a conjecture which leads to a prediction for all the higher cumulants. In the case $ρ_a=1$ and $ρ_b=0$, our conjecture gives the same universal distribution as the one obtained by Lee, Levitov and Yakovets for one dimensional quantum conductors in the metallic regime.

description: The political debate over the efficacy and desirability of registration reform has been largely disconnected from empirical evidence. This dissertation reviews historical data on electoral participation, registration laws, and electoral outcomes in order to appraise comprehensively the legitimacy of the hopes and fears of reform proponents and opponents. Building on previous efforts, this dissertation provides a more current and comprehensive analysis of the contemporary effects of National Voter Registration Act (NVRA) registration reforms. This dissertation finds that motor voter and other NVRA provisions have significant but modest effects on registration, turnout, partisan registration, and electoral outcomes. In general, interaction tests indicate that reforms disproportionately boost the participation of the single persons, young persons, and movers. Interestingly, they do not consistently appear to benefit two target groups: those with lower income and those with less education. Regarding the effect of reforms on the political composition of the pool of participants, the findings provide weak support for the inferences that motor voter programs are the registration reforms most likely to consistently produce participation increases across various political groups; the magnitude may be greatest on those least interested in politics. Moreover, tests using state-level data indicate that the greatest effect of registration reforms regarding partisan registration lies in increased registration of persons affiliated with neither major party. Regarding partisan advantage, agency-based registration programs significantly, albeit modestly, increase registration among Democrats. However, consistent with conventional academic wisdom, there is scant evidence of registration reform affecting the electoral prospects of partisans or incumbents. Finally, this dissertation provides evidence that, at least in the American system of governance, administration may be inherently political. Results suggest that partisan and regional disparities in the implementation of reforms may dampen the effect of these reforms on participation, and the regional disparity may be quite large. This preliminary result requires further review.

description: We address the enumeration of planar 4-valent maps equipped with an Eulerian orientation by two different methods, and compare the solutions we thus obtain. With the first method we enumerate these orientations as well as a restricted class which we show to be in bijection with general Eulerian orientations. The second method, based on the work of Kostov, allows us to enumerate these 4-valent orientations with a weight on some vertices, corresponding to the six vertex model. We prove that this result generalises both results obtained using the first method, although the equivalence is not immediately clear.

description: This paper analyzes the higher-order properties of nested pseudo-likelihood (NPL) estimators and their practical implementation for parametric discrete Markov decision models in which the probability distribution is defined as a fixed point. We propose a new NPL estimator that can achieve quadratic convergence without fully solving the fixed point problem in every iteration. We then extend the NPL estimators to develop one-step NPL bootstrap procedures for discrete Markov decision models and provide some Monte Carlo evidence based on a machine replacement model of Rust (1987). The proposed one-step bootstrap test statistics and confidence intervals improve upon the first order asymptotics even with a relatively small number of iterations. Improvements are particularly noticeable when analyzing the dynamic impacts of counterfactual policies.

The studies on $Z \to Υ(1S)+g+g$ at the next-to-leading-order QCD accuracy

description: In this paper, we carry out the next-to-leading-order (NLO) studies on $Z \to Υ(1S)+g+g$ via the color-singlet (CS) $b\bar{b}$ state. We find the newly calculated NLO QCD corrections to this process can significantly influence its leading-order (LO) results, and greatly improve the dependence on the renormalization scale. By including the considerable feeddown contributions, the branching ratio $\mathcal{B}_{Z \to Υ(1S)+g+g}$ is predicted to be $(0.56 \sim 0.95)\times 10^{-6}$, which can reach up to $19\% \sim 31\%$ of the LO predictions given by the CS dominant process $Z \to Υ(1S)+b+\bar{b}$. Moreover, $Z \to Υ(1S)+g+g$ also seriously affect the CS predictions on the $Υ(1S)$ energy distributions, especially when $z$ is relatively small. In summary, for the inclusive $Υ(1S)$ productions in $Z$ decay, besides $Z \to Υ(1S)+b+\bar{b}$, the gluon radiation process $Z \to Υ(1S)+g+g$ can provide indispensable contributions as well.

description: There have been improvements nationally in teenagers' self-reported health risk since the 1990s. This study provides an overview of trends in substance use, sexual health, violence and victimization, and mental health status among Chicago Public High School (CPS) students over a 20-year period. We compared responses to 29 identically worded items from the 1997, 2007, and 2017 Chicago Youth Risk Behavior Survey (YRBS) in the four domains.  We show changes in responses across individual items, mean changes across the four domains, and change in the proportion of students with highest risk exposure (10 affirmative responses).  Analyses control for CPS students grade, sex, and race/ethnicity. Reductions in substance use, sexual health risk, and violence and victimization (30, 40% and 40% in the mean number of affirmative responses, respectively) were observed. Mental health showed an initial improvement from 1997 to 2007, only to worsen by 2017 and show little difference from 1997.  There was an approximate 70% decrease in the likelihood of being in the high multiple risk category (10 affirmative responses) in 2017 compared to 1997 (OR 0.33; CI 0.22-0.49). In alignment with national trends, our study documents significant improvement in Chicago public high school students long-term health risk exposure over the 20-year study period, with the notable exception of mental health status.  These improvements occurred simultaneously with improvements in academic achievement coinciding with changes in the study population of CPS students and demographic changes in many Chicago neighborhoods.
A Class of $P,T$-Invariant Topological Phases of Interacting Electrons

description: We describe a class of parity- and time-reversal-invariant topological states of matter which can arise in correlated electron systems in 2+1-dimensions. These states are characterized by particle-like excitations exhibiting exotic braiding statistics. $P$ and $T$ invariance are maintained by a `doubling' of the low-energy degrees of freedom which occurs naturally without doubling the underlying microscopic degrees of freedom. The simplest examples have been the subject of considerable interest as proposed mechanisms for high-$T_c$ superconductivity. One is the `doubled' version (i.e. two opposite-chirality copies) of the U(1) chiral spin liquid. The second example corresponds to $Z_2$ gauge theory, which describes a scenario for spin-charge separation. Our main concern, with an eye towards applications to quantum computation, are richer models which support non-Abelian statistics. All of these models, richer or poorer, lie in a tightly-organized discrete family. The physical inference is that a material manifesting the $Z_2$ gauge theory or a doubled chiral spin liquid might be easily altered to one capable of universal quantum computation. These phases of matter have a field-theoretic description in terms of gauge theories which, in their infrared limits, are topological field theories. We motivate these gauge theories using a parton model or slave-fermion construction and show how they can be solved exactly. The structure of the resulting Hilbert spaces can be understood in purely combinatorial terms. The highly-constrained nature of this combinatorial construction, phrased in the language of the topology of curves on surfaces, lays the groundwork for a strategy for constructing microscopic lattice models which give rise to these phases.

Cold War at sea: The maritime confrontation on and over the high seas between the United States and the Soviet Union, 1945-1989
Creators: name: Winkler, David Frank
Publisher: name: American University
Year: 2023

description: Because of the freedom for all nations to travel on and over the high seas, U.S. and Soviet naval and air forces came into to daily direct contact during the Cold War. This contact was not always peaceful. During the late 1940s and 1950s, a U.S. surveillance effort at times penetrated Soviet airspace, provoking Soviet attacks. The narrative details the air incidents and follows the diplomatic efforts to contain the violence. Both sides exchanged notes and used the U.N. as a forum to air grievances. Traditional diplomatic efforts produced mixed results. During the 1960s, the Soviet Union became a major sea power with merchant, fishing fleets and a blue water navy. U.S. Navy ships and aircraft came into contact with these vessels worldwide. Each side charged harassment and collisions occurred. In April 1968, the U.S. proposed safety at sea talks. The Soviets accepted the proposal in November 1970 and an Incidents at Sea Agreement (INCSEA) was signed in Moscow in May 1972. The agreement passed its first major test during the 1973 Arab-Israeli War. During the 1970s and 1980s, naval officers met annually to discuss the effectiveness of the accord. After several benign years, changes in U.S. policy and strategy placed U.S. and Soviet ships into greater contact. As Afghanistan, KAL 007, and other events soured U.S.-Soviet relations, INCSEA became the only direct military-to-military contact and served as a venue to discuss other issues of concern. With small exceptions, the behavior of naval and air forces remained correct and professional. During the 1980s, the United States implemented an aggressive Freedom of Navigation (FON) program, testing Soviet territorial claims. During a FON demonstration in the Black Sea during February 1988, two Soviet warships rammed two American warships. The resolution of this incident concluded the Cold War at Sea. In contrast to conventional diplomatic channels, the navy-to-navy channels established under INCSEA had greater success in modifying the behavior of the two navies. This dissertation examines this observation and concludes by looking at the implications of the Cold War at Sea in the post-Cold War world.

description: If the AdS/CFT conjecture holds, every question about bulk physics can be answered by the boundary CFT. But we still don't know how to translate all the questions about bulk physics to questions about the boundary CFT. Completing this bulk-boundary dictionary is the aim of the bulk reconstruction program, which we review in these lectures. We cover the HKLL construction, bulk reconstruction in AdS/Rindler, mirror operator construction of Papadodimas and Raju and the Marolf-Wall paradox. These notes are based on lectures given at ST4 2018.

description: On March 26, 1994, President Bill Clinton signed into law Goals 2000: The Educate America Act, which established voluntary national educational standards. Developed by a grassroots consensus process led by the Department of Education, they were intended to provide guidelines for student achievement for grades K-12 in the core subjects of English, mathematics, science, foreign languages, civics and government, economics, history, geography, and the arts, including dance, music, theater, and the visual arts. For the first time in American history, dance is included as basic to education. Chapter I of this dissertation clarifies the importance of The National Standards for Arts Education in bringing the arts to attention in the national education agenda. Chapter II is a review of pertinent literature: (1) the work of philosopher John Dewey and cognitive scientists Jean Piaget and Howard Gardner, work that theoretically supports dance as an active learning experience; (2) accounts of the historical development of dance in education; (3) literature by people influential in promoting arts education: Eliot Eisner, Charles Fowler, and Diane Ravitch; (4) three major documents leading to the National Standards: A Nation at Risk, Toward Civilization, and America 2000: An Educational Strategy. Chapter III is an analysis of the debate leading to the creation of the Standards involving the National Committee for Standards in the Arts, the committee responsible for authorizing the document, and the Dance Task Force. Chapter IV focuses on the final document. It explains the pedagogic and philosophic principles underlying the National Standards, their structure, what the standards are designed to accomplish, and the results. Background information is also provided for the National Assessment Frameworks and Specifications and the "Opportunity-to-Learn Standards for Dance Education.". Chapter V addresses the future: issues of dissemination, implementation, advocacy, and a vision for dance education. It discusses issues faced by the National Committee for Standards in the Arts, the Clinton Administration, and the U.S. Department of Education concerning implementation and advocacy. It further investigates issues for the stakeholders: political legislatures, school boards and administrators, arts agencies, the business community, arts specialists, teachers, parents and students.

There is a needfor improvement in the disparity in mental healthcare that exists in ethnic minority populations to ensureequitable healthcare for all people, including ethnically diverse populations.Aims: (1) review the existing literature on barriers to mental healthcare in a specific subset of the ethnic minority (African-Americans). (2) perform a frequency analysis of the specific barriers to accessing and receiving mental healthcarecited in the literature. (3) use the barriers identified to highlight the importance of their consideration in the development and planning for population-focused intervention and care modeling.Methods: A literature review was performed using Ovid/Medline, Pubmed, ClincalKey, and Scopus databases. Barriers to mental health care for African Americans were identified and quantified through afrequency analysis. Results: 25 barrier themes were identified through the literature review and described. Conclusions: barrier recognition and population-based planning will be essential in promoting the successof future interventions and iterations of care models.

description: We measure the branching fractions and CP asymmetries in the decays B0 --> K+K-K0S and B+ --> K+K0S K0S using a sample of approximately 122 million BBbar pairs collected by the BaBar detector. From a time-dependent analysis of the K+ K- K0S sample that excludes phi K0S, the values of the CP-violation parameters are S = -0.56 +/- 0.25 +/- 0.04 and C = -0.10 +/- 0.19 +/- 0.10, where the first uncertainty is statistical, the second is systematic. We confirm that the final state is nearly purely CP-even. Using this result and setting C=0, we extract the Standard Model parameter sin2beta = 0.57 +/- 0.26 +/- 0.04 +0.17/-0 where the last error is due to uncertainty on the CP content. We present the first measurement of the CP-violating charge asymmetry ACP(B+ --> K+K0S K0S) = -0.04 +/- 0.11 +/- 0.02, with a 90% confidence-level interval of [-0.23, 0.15]. The branching fractions are BF(B0 --> K+K-K0) = (23.8 +/- 2.0 +/- 1.6) x 10^{-6} and BF(B+ --> K+K0S K0S) = (10.7 +/- 1.2 +/- 1.0) x 10^{-6}.

Green institutions in Brazil: The road from Stockholm to Rio
Creators: name: Duarte, Lilian Cristina B.

description: Brazil's performance regarding environmental issues during the 1970s and 1980s drew severe criticism from the international community. A survey of articles in the press, scholarly papers and books about environmental policies reveals that successive Brazilian administrations are described at best as indifferent to the environmental degradation of the territory; at worst as frankly unwilling to take steps to reconcile economic growth with environmental conservation. The possible exception is the overall assessment of Fernando Collor de Mello's administration, the civilian president who also chaired the United Nations Conference on Environment and Development in 1992. The signs that Brazilian administrations were not indifferent to environmental problems or to criticisms from the international community are evident since the 1970s. In October 1973, an authoritarian military administration created the Special Secretariat for the Environment (SEMA), and a national policy for the environment began to emerge. In the years that followed a complex system developed, which includes a sophisticated regulatory framework, specialized agencies and trained personnel. This research represents an effort to provide a more comprehensive and balanced perspective on the evolution of environmental environmental awareness and institution-building in Brazil over a thirty-year period that was rich with political and social changes for the country. It was also a time of significant changes in international environmentalism--as illustrated by the two environmental conferences sponsored by the United Nations (in Stockholm, in 1972, and in Rio, in 1992). Contrary to widespread perception, the Brazilian state was not a late starter as regards the adoption of an environmental agenda. In fact, Brazilian environmental institutions evolved at the interface of the country's domestic and international policies. Environmental awareness was integrated into the state's geopolitical visions of national security and development strategies, helped shape both domestic and foreign policies in Brazil and constitutes an important element of Brazilian political history and its relations with other nations.

description: Energy carrier transport and recombination in emerging semiconductors can be directly monitored with optical microscopy, leading to the measurement of the diffusion coefficient (D), a critical property for design of efficient optoelectronic devices. D is often determined by fitting a time-resolved expanding carrier profile after optical excitation using a Mean Squared Displacement (MSD) Model. Although this approach has gained widespread adoption, its utilization can significantly overestimate D due to the non-linear recombination processes that artificially broaden the carrier distribution profile. Here, we simulate diffusive processes in both excitonic and free carrier semiconductors and present revised MSD Models that take into account second-order (i.e. bimolecular) and third-order (i.e. Auger) processes to accurately recover D for various types of materials. For perovskite thin films, utilization of these models can reduce fitting error by orders of magnitude, especially for commonly deployed excitation conditions where carrier densities are > 5x10$^1$$^6$ cm$^-$$^3$. In addition, we show that commonly-deployed MSD Models are not well-suited for the study of films with microstructure, especially when boundary behavior is unknown and feature sizes are comparable to the diffusion length. Finally, we find that photon recycling only impacts energy carrier profiles on ultrashort time scales or for materials with fast radiative decay times. We present clear strategies to investigate energy transport in disordered materials for more effective design and optimization of electronic and optoelectronic devices.

description: We are developing position sensitive silicon detectors (PSDs) which have an electrode at each of four corners so that incident position of a charged particle can be obtained with signal from the electrodes. It is expected that the position resolution of the electromagnetic calorimeter (ECAL) of the ILD detector will be improved by introducing PSDs to detection layers. We have been developing the PSDs for several years. In the previous production we found that the charge separation is not optimally done due to the readout impedance. To solve the issue, we produced new PSDs with higher surface resistance with an additional resistive layer on the surface. We also implemented several techniques to decrease position distortion and increase signal-to-noise ratio which are essential for the optimal position resolution. The measurements on the prototype sensors are ongoing, including radiation source measurement and laser measurement using an ASIC for silicon pad detectors.

description: We provide a method for analytically constructing high-accuracy templates for the gravitational wave signals emitted by compact binaries moving in inspiralling eccentric orbits. By contrast to the simpler problem of modeling the gravitational wave signals emitted by inspiralling {\it circular} orbits, which contain only two different time scales, namely those associated with the orbital motion and the radiation reaction, the case of {\it inspiralling eccentric} orbits involves {\it three different time scales}: orbital period, periastron precession and radiation-reaction time scales. By using an improved `method of variation of constants', we show how to combine these three time scales, without making the usual approximation of treating the radiative time scale as an adiabatic process. We explicitly implement our method at the 2.5PN post-Newtonian accuracy. Our final results can be viewed as computing new `post-adiabatic' short period contributions to the orbital phasing, or equivalently, new short-period contributions to the gravitational wave polarizations, $h_{+,\times}$, that should be explicitly added to the `post-Newtonian' expansion for $h_{+,\times}$, if one treats radiative effects on the orbital phasing of the latter in the usual adiabatic approximation. Our results should be of importance both for the LIGO/VIRGO/GEO network of ground based interferometric gravitational wave detectors (especially if Kozai oscillations turn out to be significant in globular cluster triplets), and for the future space-based interferometer LISA.

description: Prior research has shown that “self-focus [can] bring about self-evaluation and thus make meeting a goal more important” to an individual (Paul, 2012, p. 192). In this regard, self-focus and self-evaluation may be involved in the presence of mirrors. This research explored whether the presence of a mirror impacts sustainable waste behaviour of participants at the University of British Columbia. The Forestry Building and the Life Sciences Building were the two locations in this study. Within each building, there was a mirrored station, which was the experimental condition, and a non-mirrored station, which was the control condition. The researchers weighed each bin and noted the number of contaminants - operationalized as incorrectly disposed rubbish - within each container, resulting in a ratio of contaminants per kilogram. An independent samples t -test was used on the ratio of contaminants per kilogram in garbage, organics, paper, and recycling, all of which were statistically insignificant. Secondly, we used an independent samples t-test on the weight and number of contaminants in each bin; all contamination rates were statistically insignificant. Limitations to our research follow, as well as implications and recommendations for future studies in regards to sustainable waste behaviour.

description: Botryllophilus kozloffi Ooishi, 2014
 Material examined. 1 ♀ (MNHN-IU-2018-1963) in Clavel ẚna lepadẚfçrmẚs (Müller, 1776), Île Grande, Atlantic coast of France; 1 ♀ (MNHN-IU-2014-17370, dissected) in Cystçdytes senegalense Monniot F., 1969, Dakar, Senegal; 3 ♀♀ (MNHN-IU-2018-1964, 1 ♀ dissected) in Cystçdytes rçseçlus Hartmeyer, 1912 (MNHN-IT-2008-2602 = MNHN A3 / CYS/4), Dakar, Senegal Stn. 17, IFAN coll., 21 January 1941.
 Remarks. Ooishi (2014c) described this species based on specimens associated with Clavelẚna lepadẚfçrmẚs collected from the Atlantic coast of France. Cystçdytes senegalense and C. rçseçlus reported above are new host records. Almost all morphological features of our new material agree well with the original description, except for the absence of a pair of setulose lobes on the anteromedial margin of the first endopodal segment of right and left leg 1, which were described and figured in the original description.
 This species is very similar to B. neapçlẚtanus Ooishi, 2006. Both have the same setation pattern on the antenna and the swimming legs. Ooishi (2014c) listed several differences between the two species, the most easily observed of which appears to be leg 5, which is short and stout in B. kçzlçffẚ but longer and tapering in B. neapçlẚtanus.
