description: We show that the jet structure of DM annihilation or decay products enhances the anti-deuterium production rate by orders of magnitude compared to the previous computations done assuming a spherically symmetric coalescence model. In particular, in the limit of heavy DM, M >> m_p, we get a constant rather than 1/M^2 suppressed anti-deuterium production rate. Therefore, a detectable anti-deuterium signal is compatible with the lack of an excess in the anti-proton PAMELA flux. Most importantly, cosmic anti-deuterium searches become sensitive to the annihilations or decays of heavy DM, suggesting to extend the experimental anti-deuterium searches above the O(1) GeV scale.

description: Background: Studies of long-term malaria cohorts have provided essential insights into how Plasmodium falciparum interacts with humans, and influences the development of antimalarial immunity. Immunity to malaria is acquired gradually after multiple infections, some of which present with clinical symptoms. However, there is considerable variation in the number of clinical episodes experienced by children of the same age within the same cohort. Understanding this variation in clinical symptoms and how it relates to the development of naturally acquired immunity is crucial in identifying how and when some children stop experiencing further malaria episodes. Where variability in clinical episodes may result from different rates of acquisition of immunity, or from variable exposure to the parasite. Methods: Using data from a longitudinal cohort of children residing in an area of moderate P. falciparum transmission in Kilifi district, Kenya, we fitted cumulative episode curves as monotonic-increasing splines, to 56 children under surveillance for malaria from the age of 5 to 15. Results: There was large variability in the accumulation of numbers of clinical malaria episodes experienced by the children, despite being of similar age and living in the same general location. One group of children from a particular sub-region of the cohort stopped accumulating clinical malaria episodes earlier than other children in the study. Despite lack of further clinical episodes of malaria, these children had higher asymptomatic parasite densities and higher antibody titres to a panel of P. falciparum blood-stage antigens. Conclusions: This suggests development of clinical immunity rather than lack of exposure to the parasite, and supports the view that this immunity to malaria disease is maintained by a greater exposure to P. falciparum, and thus higher parasite burdens. Our study illustrates the complexity of anti-malaria immunity and underscores the need for analyses which can sufficiently reflect the heterogeneity within endemic populations.

description: We present infrared photometry of the episodic dust-making Wolf-Rayet system WR19 (LS3), tracking its fading from a third observed dust-formation episode in 2007 and strengthening the view that these episodes are periodic (P = 10.1+/-0.1 y). Radial velocities of the O9 component observed between 2001 and 2008 show RV variations consistent with WC19 being a spectroscopic binary of high eccentricity (e=0.8), having periastron passage in 2007.14, shortly before the phase of dust formation. In this respect, WR19 resembles the archetypical episodic dust-making colliding-wind binary system WR140.

description: A new scenario of hybrid-like inflation is considered for sneutrino and MSSM fields. Contrary to the usual hybrid inflation model, the direct coupling between a trigger field and the sneutrino/MSSM inflaton field is not necessary for the scenario. The dissipation and the radiation from the sneutrino/MSSM inflaton can be written explicitly by using the Yukawa couplings. Remote inflation does not require the shift symmetry or cancellation in solving the eta-problem.

Space-time Methods for Time-dependent Partial Differential Equations

description: Modern discretizations of time-dependent PDEs consider the full problem in the space-time cylinder and aim to overcome limitations of classical approaches such as the method of lines (first discretize in space and then solve the resulting ODE) and the Rothe method (first discretize in time and then solve the PDE). A main advantage of a holistic space-time method is the direct access to space-time adaptivity and to the backward problem (required for the dual problem in optimization or error control). Moreover, this allows for parallel solution strategies simultaneously in time and space. Several space-time concepts where proposed (different conforming and nonconforming space-time finite elements, the parareal method, wavefront relaxation etc.) but this topic has become a rapidly growing field in numerical analysis and scientific computing. In this workshop the focus is the development of adaptive and flexible space-time discretization methods for solving parabolic and hyperbolic space-time partial differential equations.

description: The problem of determining unknown quantities in a PDE from measurements of (part of) the solution to this PDE arises in a wide range of applications in science, technology, medicine, and finance. The unknown quantity may e.g. be a coefficient, an initial or a boundary condition, a source term, or the shape of a boundary. The identification of such quantities is often computationally challenging and requires profound knowledge of the analytical properties of the underlying PDE as well as numerical techniques. The focus of this workshop was on applications in phase retrieval, imaging with waves in random media, and seismology of the Earth and the Sun, a further emphasis was put on stochastic aspects in the context of uncertainty quantification and parameter identification in stochastic differential equations. Many open problems and mathematical challenges in application fields were addressed, and intensive discussions provided an insight into the high potential of joining deep knowledge in numerical analysis, partial differential equations, and regularization, but also in mathematical statistics, homogenization, optimization, differential geometry, numerical linear algebra, and variational analysis to tackle these challenges.
Optimal control of number squeezing in trapped Bose-Einstein condensates

description: We theoretically analyze atom interferometry based on trapped ultracold atoms, and employ optimal control theory in order to optimize number squeezing and condensate trapping. In our simulations, we consider a setup where the confinement potential is transformed from a single to a double well, which allows to split the condensate. To avoid in the ensuing phase-accumulation stage of the interferometer dephasing due to the nonlinear atom-atom interactions, the atom number fluctuations between the two wells should be sufficiently low. We show that low number fluctuations (high number squeezing) can be obtained by optimized splitting protocols. Two types of solutions are found: in the Josephson regime we find an oscillatory tunnel control and a parametric amplification of number squeezing, while in the Fock regime squeezing is obtained solely due to the nonlinear coupling, which is transformed to number squeezing by peaked tunnel pulses. We study splitting and squeezing within the frameworks of a generic two-mode model, which allows us to study the basic physical mechanisms, and the multi-configurational time dependent Hartree for bosons method, which allows for a microscopic modeling of the splitting dynamics in realistic experiments. Both models give similar results, thus highlighting the general nature of these two solution schemes. We finally analyze our results in the context of atom interferometry.

description: It is argued that the general four-dimensional extremal Kerr-Newman-AdS-dS black hole is holographically dual to a (chiral half of a) two-dimensional CFT, generalizing an argument given recently for the special case of extremal Kerr. Specifically, the asymptotic symmetries of the near-horizon region of the general extremal black hole are shown to be generated by a Virasoro algebra. Semiclassical formulae are derived for the central charge and temperature of the dual CFT as functions of the cosmological constant, Newton's constant and the black hole charges and spin. We then show, assuming the Cardy formula, that the microscopic entropy of the dual CFT precisely reproduces the macroscopic Bekenstein-Hawking area law. This CFT description becomes singular in the extreme Reissner-Nordstrom limit where the black hole has no spin. At this point a second dual CFT description is proposed in which the global part of the U(1) gauge symmetry is promoted to a Virasoro algebra. This second description is also found to reproduce the area law. Various further generalizations including higher dimensions are discussed.

description: A common feature shared by many natural objects arising in probability theory is that they tend to be very “rough”, as opposed to the “smooth” objects usually studied in other branches of mathematics. It is however still desirable to understand their geometric properties, be it from a metric, a topological, or a measure-theoretic perspective. In recent years, our understanding of such “random geometries” has seen spectacular advances on a number of fronts.
Feasibility of scheduled helicopter service in the Vancouver area
Creators: name: Marko, David Harry
Publisher: name: University of British Columbia
Year: 2011

description: The objective of this thesis is to determine whether a scheduled helicopter service is feasible in the Vancouver area. The helicopter can provide the major advantage of transportation directly to the center of any area, be it downtown or an airport terminal building, at speeds in excess of those attainable by most surface modes of travel. This potential for time savings makes a helicopter service commonly desirable. However, cost and revenue considerations are critical to the implementation of a helicopter service. Cost and revenue estimates have been proposed, developed and tested for applicability in the Vancouver area. Consideration of cost and revenue data allowed conclusions regarding commercial feasibility. Study of benefits and costs external to the helicopter operation itself then permitted examination of the economic feasibility of a scheduled helicopter service in the Vancouver area. The subject of this thesis is recognized as being both broad and complex. This study is but a brief investigation of the subject and only some of the major forces have been considered. In fact, any one major section of this thesis could warrant a significantly large study in itself. It was deemed worthwhile to embark on the entire study while recognizing that only the major factors could be considered as the value of the entire project would almost certainly be of greater value than any one of the parts. Restricting the thesis to the study of either costs, revenues or benefits would not allow conclusions regarding commercial or economic feasibility. Conclusions to the broader problem were deemed desirable. The annual operating cost for a fleet of three S-61-N helicopters has been estimated at $3.2 million. The forecast revenues for a route serving Victoria, Vancouver Airport, Vancouver downtown, Comox, Powell River and Campbell River are $1.48 million, $1.58 million and $1.69 million for 1968, 1969 and 1970 respectively. Resulting losses which exclude any capital cost allowance are $1.72 million in 1968, $1.62 million in 1969 and $1.51 million in 1970. A sensitivity analysis indicates that even if revenues were doubled (a highly unlikely possibility) from twice the forecast number of passengers with fares constant or visa versa, service would still incur a $0.24 million loss in 1968. A study of the indirect benefits that could accrue from this hypothetical service indicates little justification for government subsidization. Airline financial assistance, particularly for the significant amount required does not appear warranted. Lack of forecast commercial feasibility and insufficient justification for government subsidization or airline assistance to compensate for the difference leads to the conclusion that a scheduled helicopter service in the Vancouver area is not feasible although it is operationally possible.

description: Many studies have discussed the factors influencing hearing outcomes after cochlear implantation, but few have addressed improvements in speech perception for these patients over time. To investigate the relationship between preoperative factors and the pattern of longitudinal improvement in speech perception following cochlear implantation (CI). This study enrolled 83 patients (96 ears) who underwent CI at Shinshu University Hospital. The patients were assessed up to 12 months after CI by a monosyllable test, and showed either delayed improvement (DI), early improvement (EI), or stable improvement (SI) when compared with their preoperative score. Eight preoperative variables were also examined for their effects on speech perception over time. The DI, EI, SI groups comprised 35.4%, 43.8%, and 20.8% of all patients, respectively. Patients in the DI group were older at surgery than those in the EI and SI groups, and their onset age were also older than that in the SI group. No other preoperative variables showed significant differences across the three groups. Our findings revealed that age at implantation and age at onset of hearing loss significantly affected the improvement pattern of speech perception. Age may be useful in predicting recovery of speech perception after CI.

description: Linear-assignment Gel'fand-Pinsker coding (LA-GPC) is a coding technique for channels with interference known only at the transmitter, where the known interference is treated as side-information (SI). As a special case of LA-GPC, dirty paper coding has been shown to be able to achieve the optimal interference-free rate for interference channels with perfect channel state information at the transmitter (CSIT). In the cases where only the channel distribution information at the transmitter (CDIT) is available, LA-GPC also has good (sometimes optimal) performance in a variety of fast and slow fading SI channels. In this paper, we design the filters in nested-lattice based coding to make it achieve the same rate performance as LA-GPC in multiple-input multiple-output (MIMO) channels. Compared with the random Gaussian codebooks used in previous works, our resultant coding schemes have an algebraic structure and can be implemented in practical systems. A simulation in a slow-fading channel is also provided, and near interference-free error performance is obtained. The proposed coding schemes can serve as the fundamental building blocks to achieve the promised rate performance of MIMO Gaussian broadcast channels with CDIT or perfect CSIT

We follow Dziobek's approach to four body central configurations with a direct implicit method of our own in which the fundamental quantities are the quotient of the directed area divided by the corresponding mass and a new simple numerical algorithm is developed to construct general four body central configurations. This tool is applied to obtain new properties of the symmetric and non-symmetric central configurations. The explicit continuous connection between three body and four body central configurations where one of the four masses approaches zero is clarified. Some cases of coorbital 1+3 problems are also considered.

The principal Hugoniot points derived from the equation of state agree well with the available experimental data. With the increase of pressure, molecular dissociation is observed. Electron spin polarization determines the electronic structure of the system under low pressure, while it is suppressed around 30 $\sim$ 50 GPa. Particularly, nonmetal-metal transition is taken into account, which also occurs at about 30 $\sim$ 50 GPa. In addition, the optical properties of shock compressed oxygen are also discussed.

description: The importance of developing positive financial behaviors early in life is being demonstrated every day as the economic fallout surrounding the ongoing COVID-19 pandemic heightens. Though a personal finance education does not solve for lack of income and systemic economic inequality, it does inform individuals on healthy spending and saving habits to help them weather through periods of economic duress. This thesis explores the importance of developing financial well-being among college students, specifically, undergraduate students of the University of Texas at Austin. Recent college graduates are facing significantly different financial circumstances than previous generations. These circumstances have been shaped in large part by the rising cost of attending college and the associated student loan crisis. In 2019, total student loan debt in the United States passed $1.6 trillion and is expected to reach $2 trillion in the next two years. In addition to growing debt, graduates of the class of 2020 are also facing weary job prospects as employment opportunities dwindle amid the current pandemic. To determine the state of financial well-being among UT-Austin undergraduates I conducted a study regarding students’ financial literacy and behaviors. Based on the study’s results, I outline the need for comprehensive personal finance initiatives and offer recommendations on how UT-Austin can improve the financial well-being of students. First, I address the importance of financial well-being and insights from the current economic climate. Next, I explain the current state of consumer financial well-being in the U.S. before diving into the results of my UT-Austin study. Then, I examine existing personal finance education initiatives from several organizations before finally proposing a plan for how UT-Austin can develop its own student financial well-being initiatives based existing models of success.

description: We consider stability of spherically symmetric solutions in $f(R)$ gravity model proposed by Starobinsky. We find that the model suffers from a severe fine tuning problem when applied to compact objects like neutron stars. The problem can be remedied by introducing a cut off on the mass of the scalar degree of freedom present in the model. A new mass scale associated with neutron stars density is then required for the stabilities of $f(R)$ gravity solutions inside relativistic stars.

description: Balance deficits increase the risk of falls and compromise quality of life. Current treatment modalities do not resolve symptoms for many patients. To measure changes in objective posturography after a computerized vestibular retraining therapy protocol. This was a single-arm interventional study of individuals with a stable unilateral vestibular deficit present for greater than six months. Participants underwent 12 twice-weekly sessions of computerized vestibular retraining therapy. Objective response was measured by the Sensory Organization Test and questionnaires were administered to measure subjective changes. We enrolled 13 participants (5 females and 8 males) with a median age of 51 years (range 18 to 67). After retraining, the Sensory Organization Test composite score improved by 8.8 (95% CI 0.6 to 19.1) and this correlated with improvement in the Falls Efficacy Scale-International questionnaire (rs −0.6472; 95% CI −0.8872 to − 0.1316). Participants with moderate-to-severe disability at baseline (n = 7) demonstrated greater improvement in the composite score (14.6; 95% CI 7.0 to 36.9). Computerized vestibular retraining therapy for stable unilateral vestibular deficits is associated with improvement in dynamic balance performance. Posturography improvements correlated with a reduction in perceived fall risk. Trial Registration Information Clinicaltrials.gov registration NCT04875013; 04/27/2021

description: Extremist groups are something that people hear about frequently enough that everyone is familiar with the term. They consist of people and/or groups with an ideology that exceeds the normal, and often, are brought to the attention of the public when they act out in accordance with the extreme beliefs. This paper seeks to examine past the question of if a system of beliefs is extreme, and instead targets the question of how it came to be that way. This paper will use the theory of J.M. Berger, who through a historical analysis of one known extremist group, claims his theory to be a “universal process of extremization”. Using two extremist ideologies from vastly different sides of the ideological and political spectrum, the Weathermen and Bronze Age Pervert, my research seeks to test out the “universal” claims of Berger’s theory, as well as determine the future value of such a theory, as a mean of prediction and intervention for future violence for extremist groups.

description: This paper offers a conceptually straightforward method for the calculation of stresses in polarisable media based on the notion of a drive form and its property of being closed in spacetimes with symmetry. After an outline of the notation required to exploit the powerful exterior calculus of differential forms, a discussion of the relation between Killing isometries and conservation laws for smooth and distributional drive forms is given. Instantaneous forces on isolated spacetime domains and regions with interfaces are defined, based on manifestly covariant equations of motion. The remaining sections apply these notions to media that sustain electromagnetic stresses, with emphasis on homogeneous magnetoelectric material. An explicit calculation of the average pressure exerted by a monochromatic wave normally incident on a homogeneous, magnetoelectric slab in vacuo is presented and the concluding section summarizes how this pressure depends on the parameters in the magnetoelectric tensors for the medium.

description: Since the 1970s, flame retardant chemicals have been increasingly used to meet fire safety regulations. However, although these flame retardant chemicals improve fire safety, they can also pose a risk to health and the environment. Some of the popular flame retardant chemicals in use tend to accumulate in the environment. Humans and wildlife are then exposed to these flame retardant chemicals, which can cause a variety of adverse health effects. Although certain flame retardant chemicals have been banned or phased out, products that contain them are still in use, and the popular replacements for these chemicals have not been adequately tested to determine their effects. Currently, there is a policy question as to whether the potential increase to fire safety outweighs the potential risk to health and environmental safety. health, and the environment. exterior thickness of the object. Some standards require the use of flame retardant chemicals, even though they pose risks. Additional testing should be performed to determine whether such flame retardant chemicals are required or if the use of such chemicals could be reduced or eliminated. As such, this thesis discusses tests performed on 3D printed containers made out of both flame retardant and non-flame retardant ABS. These containers were exposed to an internal source of fire to determine how the flame retardant ABS performed compared to the non-flame retardant ABS. In some cases, flame retardant chemicals may not be necessary. In order to avoid the usage of potentially dangerous chemicals, such alternatives should be carefully considered.

description: Type A N-fold supercharge admits a one-parameter family of factorizations into product of N first-order linear differential operators due to an underlying GL(2,C) symmetry. As a consequence, a type A N-fold supersymmetric system can have different intermediate Hamiltonians corresponding to different factorizations. We derive the necessary and sufficient conditions for the latter system to possess intermediate Hamiltonians for the N=2 case. We then show that whenever it has (at least) one intermediate Hamiltonian, it can admit second-order parasupersymmetry and a generalized 2-fold superalgebra. As an illustration, we construct a set of generalized Poeschl--Teller potentials of this kind.

Heating rates for an atom in a far-detuned optical lattice
Creators: name: Gerbier, Fabrice

Publisher: name: arXiv
Year: 2010
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: We calculate single atom heating rates in a far detuned optical lattice, in connection with recent experiments. We first derive a master equation, including a realistic atomic internal structure and a quantum treatment of the atomic motion in the lattice. The experimental feature that optical lattices are obtained by superimposing laser standing waves of different frequencies is also included, which leads to a micromotional correction to the light shift that we evaluate. We then calculate, and compare to experimental results, two heating rates, the "total" heating rate (corresponding to the increase of the total mechanical energy of the atom in the lattice), and the ground bande heating rate (corresponding to the increase of energy within the ground energy band of the lattice).

description: For my Plan II Senior Thesis, I plan to research and analyze the role empathy plays in healthcare. I am interested in how a healthcare providers use of empathy as a tool for connecting and communication in their relationships with patients will impact overall health and a doctor’s relationship with the community through close reading and analysis. I plan to focus this research through a case study of the University of Texas’s athletic trainers, athletic training students, and their patients, i.e. the athletes. By analyzing athletic trainer’s self-rated empathy levels in interactions with their patients and students evaluated empathy levels from their preceptors, I will analyze the athletic training student’s beliefs on clinical empathy, how self-rated versus evaluated empathy relate, how empathetic interactions fair across years of experience, and how this all affects the athletes care. I hope to gain insight into the importance of empathy in the unique athletic trainer and patient relationship. Overall, I will dissect how providers use empathy when interacting with patients and how that influences a patient’s experience and path to health.
Study of the relationship between profit rates and economic concentration in a sample of Canadian industry
Creators: name: Smith, Milo Alastair
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to test the hypothesis, derived from neo-classical micro-economic theory, that other things being equal the more concentrated an industry becomes, the more likely it is that firms in that industry can pursue monopolistic practices and thereby earn greater profits than would otherwise be possible if there were more firms in that industry. The method of study employed is the application of regression and correlation analysis to a cross-sectional sample of Canadian industry. The results of this study lead one to the conclusion that concentration and profits are positively correlated, thus supporting the hypothesis. However, concentration explains only about 10 per cent of the variation in industry profit rates in the cross-section.

New approach to low energy Virtual Compton Scattering and generalized polarizabilities of the nucleon
Creators: name: Gorchtein, Mikhail

Subjects: subject: Nuclear Theory (nucl-th)

description: Virtual Compton scattering off the nucleon (VCS) is studied in the regime of low energy of the outgoing real photon. This regime allows one to directly access the generalized polarizabilities of the nucleon in a VCS experiment. In the derivation of the low energy theorem for VCS that exists in the literature, the low energy limit taken for virtual initial photons does not match on that for real photons, when one approaches the initial photon's mass shell. While this problem has for a long time been attributed to the non-analyticity of the Compton amplitude with respect to the photon virtuality, I demonstrate that it is merely due to an ill-defined low energy limit for VCS, on one hand, and to a particular way of constructing the VCS amplitude, use in the literature, on the other. I provide a uniform description of low energy Compton scattering with real and virtual photons by defining a Lorentz-covariant operator sub-basis for Compton scattering in that regime, that has six independent structures. Correspondingly, six new generalized polarizabilities are introduced in the Breit frame. These polarizabilities are defined as continuous functions of the photon virtuality and at the real photon point match onto the nucleon polarizabilities known from real Compton scattering.

Geometric Structures in Group Theory
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2017
Subjects: subject: Konferenzschrift
subject: 510

description: Geometric group theory has natural connections and rich interfaces with many of the other major fields of modern mathematics. The basic motif of the field is the construction and exploration of actions by infinite groups on spaces that admit further structure, with an emphasis on geometric structures of different sorts: one usually seeks actions in order to illuminate the structure of groups of particular interest, but one also explores actions in order to understand the underlying spaces. The dramatic growth of the field in the late twentieth century was closely associated with the study of generalized forms of non-positive and negative curvature, and classically the spaces at hand were cell complexes with some additional structure. But the scope of the field, the range of groups embraced by its techniques, and the nature of the spaces studied, have expanded enormously in recent years, and they continue to do so. This meeting provided an exciting snapshot of some of the main strands in the recent development of the subject.
