The Crab Nebula as a standard candle in very high-energy astrophysics

Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The continuum high-energy gamma-ray emission between 1 GeV and 100 TeV from the Crab Nebula has been measured for the first time in overlapping energy bands by the Fermi large-area telescope (Fermi/LAT) below ~ 100 GeV and by ground-based imaging air Cherenkov telescopes (IACTs) above ~ 60 GeV. To follow up on the phenomenological approach suggested by Hillas et al. (1998), the broad band spectral and spatial measurement (from radio to low-energy gamma-rays < 1 GeV) is used to extract the shape of the electron spectrum. While this model per construction provides an excellent description of the data at energies < 1 GeV, the predicted inverse Compton component matches the combined Fermi/LAT and IACT measurements remarkably well after including all relevant seed photon fields and fitting the average magnetic field to B = (124 +/- 6 (stat.) +15 / -6 (sys.)) μG. The close match of the resulting broad band inverse Compton component with the combined Fermi/LAT and IACTs data is used to derive instrument specific energy-calibration factors. These factors can be used to combine data from Fermi/LAT and IACTs without suffering from systematic uncertainties on the common energy scale. As a first application of the cross calibration, we derive an upper limit to the diffuse gamma-ray emission between 250 GeV and 1 TeV based upon the combined measurements of Fermi/LAT and the H.E.S.S. ground-based Cherenkov telescopes. Finally, the predictions of the magneto-hydrodynamic flow model of Kennel & Coroniti (1984) are compared to the measured SED.

Waiting time distributions in hybrid models of motor-bead assays: A concept and tool for inference

description: In single-molecule experiments, the dynamics of molecular motors are often observed indirectly by measuring the trajectory of an attached bead in a motor-bead assay. In this work, we propose a method to extract the step size and stalling force for a molecular motor without relying on external control parameters. We discuss this method for a generic hybrid model that describes bead and motor via continuous and discrete degrees of freedom, respectively. Our deductions are solely based on the observation of waiting times and transition statistics of the observable bead trajectory. Thus, the method is non-invasive, operationally accessible in experiments and can, in principle, be applied to any model describing the dynamics of molecular motors. We briefly discuss the relation of our results to recent advances in stochastic thermodynamics on inference from observable transitions. Our results are confirmed by extensive numerical simulations for parameters values of an experimentally realized F1-ATPase assay.
Arithmetic Torelli maps for cubic surfaces and threefolds

Publisher: name: arXiv
Year: 2010
Subjects: subject: Algebraic Geometry (math.AG)

description: It has long been known that to a complex cubic surface or threefold one can canonically associate a principally polarized abelian variety. We give a construction which works for cubics over an arithmetic base. This answers, away from the prime 2, an old question of Deligne and a recent question of Kudla and Rapoport. We further classify the Mumford-Tate groups of the abelian varieties which arise, and give additional arithmetic applications.

description: We define zeta-functions of weight lattices of compact connected semisimple Lie groups. If the group is simply-connected, these zeta-functions coincide with ordinary zeta-functions of root systems of associated Lie algebras. In this paper we consider the general connected (but not necessarily simply-connected) case, prove the explicit form of Witten's volume formulas for these zeta-functions, and further prove functional relations among them which include their volume formulas.

description: The expressions for the differential cross section and of the polarization observables for the reaction $\bar p+p\rightarrow e^++e^-$ are given in terms of the nucleon electromagnetic form factors in the laboratory system. Radiative corrections due to the emission of virtual and real soft photons from the leptons are also calculated. Unlike the center-of- mass system case, they depend on the scattering angle. Polarization effects are derived in the case when the antiproton beam, the target and the electron in the final state are polarized. Numerical estimations have been done for all observables for the PANDA experimental conditions using models for the nucleon electromagnetic form factors in the time-like region. The radiative corrections to the differential cross section are calculated as function of the beam energy and of the electron angle.

description: Reactive single-step hot-pressing at 1473 K and 35 MPa for 4 h produces dense, bulk, near single-phase, low-cost and low-criticality Fe$_2$Al$_{1.15}$B$_2$ and Fe$_2$Al$_{1.1}$B$_2$Ge$_{0.05}$Ga$_{0.05}$ MAB samples, showing a second-order magnetic phase transition with favorable magnetocaloric properties around room temperature. The magnetic as well as magnetocaloric properties can be tailored upon Ge and Ga doping, leading to an increase of Curie temperature $T_C$ and spontaneous magnetization $m_S$. The maximum isothermal entropy change $Δs_{T,max}$ of hot-pressed Fe$_2$Al$_{1.15}$B$_2$ in magnetic field changes of 2 and 5 T amounts to 2.5 and 5 J(kgK)$^{-1}$ at 287.5 K and increases by Ge and Ga addition to 3.1 and 6.2 J(kgK)$^{-1}$ at 306.5 K, respectively. The directly measured maximum adiabatic temperature change $ΔT_{ad,max}$ is improved by the composition modification from 0.9 to 1.1 K in magnetic field changes of 1.93 T. Overall, we demonstrate that hot-pressing provides a much faster, more scalable and processing cost reducing alternative compared to conventional synthesis routes to produce heat exchangers for magnetic cooling devices. Therefore, our criticality assessment shows that hot-pressed Fe-based MAB phases provide a promising compromise of material and processing cost, criticality and magnetocaloric performance, demonstrating the potential for low-cost and low-criticality magnetocaloric applications around room temperature.
Hybrid rendering : in pursuit of real-time raytracing
Creators: name: Demoullin, Francois M.
Publisher: name: University of British Columbia
Year: 2020

description: Hybrid rendering combines ray-tracing and rasterization graphics techniques to generate visually accurate photorealistic computer-generated images at a tight real-time frame rate. This thesis presents contributions to the field of hybrid rendering by introducing an open-source ray-traced ambient occlusion workload, by quantifying the performance tradeoffs of this workload and by evaluating one promising hardware technique to accelerate real-time raytracing. In this thesis, we introduce the first open-source implementation of a viewpoint independent raytraced ambient occlusion GPU compute benchmark. We study this workload using a cycle-level GPU simulator and present the trade-offs between performance and quality. We show that some ray-traced ambient occlusion is possible on a real-time frame budget but that the full quality effect is still too computationally expensive for today's GPU architectures. This thesis provides a limit study of a new promising technique, Hash-Based Ray Path Prediction (HRPP), which exploits the similarity between rays to predict leaf nodes to avoid redundant acceleration structure traversals. Our data shows that acceleration structure traversal consumes a significant proportion of the raytracing rendering time regardless of the platform or the target image quality. Our study quantifies unused ray locality and evaluates the theoretical potential for improved ray traversal performance for both coherent and seemingly incoherent rays. We show that HRPP can skip, on average, 40\% of all hit-all traversal computations. We further show that the significant memory overhead, ranging on the order of megabytes, inhibits this technique from being feasible for current architectures.

description: The use of the coronal approximation to model line emission from the solar transition region has led to discrepancies with observations over many years, particularly for Li- and Na-like ions. Studies have shown that a number of atomic processes are required to improve the modelling for this region, including the effects of high densities, solar radiation and charge transfer on ion formation. Other non-equilibrium processes, such as time dependent ionisation and radiative transfer, are also expected to play a role. A set of models which include the three relevant atomic processes listed above in ionisation equilibrium has recently been built. These new results cover the main elements observed in the transition region. To assess the effectiveness of the results, the present work predicts spectral line intensities using differential emission measure modelling. Although limited in some respects, this differential emission measure modelling does give a good indication of the impact of the new atomic calculations. The results are compared to predictions of the coronal approximation and to observations of the average, quiet Sun from published literature. Significant improvements are seen for the line emission from Li- and Na-like ions, inter-combination lines and many other lines. From this study, an assessment is made of how far down into the solar atmosphere the coronal approximation can be applied, and the range over which the new atomic models are valid.

description: We calculated the energy spectra of the neutron-rich He $Λ$ hypernuclei with $A=6$ to 9 within the framework of an $α+ Λ+Xn$ ($X=1$--4) cluster model using the cluster orbital shell model. The employed constituent particles reproduce their observed properties. For resonant states of core nuclei such as $^5$He, $^6$He, and $^7$He, the complex scaling method is employed to obtain energies and decay widths. The calculated ground states of $^6_Λ$He and $^7_Λ$He are in good agreement with published data. The energy levels of $^8_Λ$He and $^9_Λ$He are predicted. In $^9_Λ$He, we find one deeply bound state and two excited resonant states, which are proposed to be produced at the Japan proton accelerator research complex (J-PARC) by the double-charge-exchange reaction $(π^-, K^+)$ using a $^9$Be target.

Macroscopic constraints for the minimum entropy production principle

Publisher: name: arXiv
Year: 2011
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: In an essential and quite general setup, based on networks, we identify Schnakenberg's observables as the constraints that prevent a system from relaxing to equilibrium, showing that, in the linear regime, steady states satisfy a minimum entropy production principle. The result is applied to master equation systems, opening a new path to a well-known version of the principle regarding invariant states. Moreover, with the aid of a simple example, the principle is shown to conform to Prigogine's original formulation. Finally, we discuss analogies and differences with a recently proposed maximum entropy production principle.

description: Knowledge-first epistemology includes a knowledge norm of action: roughly, act only on what you know. This norm has been criticized, especially from the perspective of so-called standard decision theory. Mueller and Ross provide example decision problems which seem to show that acting properly cannot require knowledge. I argue that this conclusion depends on applying a particular decision theory (namely, Savage-style Expected Utility Theory) which is ill-motivated in this context. Agents’ knowledge is often most plausibly formalized as an ambiguous epistemic state, and the theory of decision under ambiguity is then the appropriate modeling tool. I show how to model agents as acting rationally on the basis of their knowledge according to such a theory. I conclude that the tension between the knowledge norm of action and formal decision theory is illusory; the knowledge-first paradigm should be used to actively select the decision-theoretical tools that can best capture the knowledge-based decisions in any given situation.

description: We report a study on the relationship between structure and electron transport properties of nanoscale graphene/pentacene interfaces. We fabricated graphene/pentacene interfaces from 10-30 nm thick needle-like pentacene nanostructures down to two-three layers (2L-3L) dendritic pentacene islands, and we measured their electron transport properties by conductive atomic force microscopy (C-AFM). The energy barrier at the interfaces, i.e. the energy position of the pentacene highest occupied molecular orbital (HOMO) with respect to the Fermi energy of the graphene and the C-AFM metal tip, are determined and discussed with the appropriate electron transport model (double Schottky diode model and Landauer-Buttiker model, respectively) taking into account the voltage-dependent charge doping of graphene. In both types of samples, the energy barrier at the graphene/pentacene interface is slightly larger than that at the pentacene/metal tip interface, resulting in 0.47-0.55 eV and 0.21-0.34 eV, respectively, for the 10-30 nm thick needle-like pentacene islands, and in 0.92-1.44 eV and 0.67-1.05 eV, respectively, for the 2L-3L thick dendritic pentacene nanostructures. We attribute this difference to the molecular organization details of the pentacene/graphene heterostructures, with pentacene molecules lying flat on the graphene in the needle-like pentacene nansotructures, while standing upright in 2L-3L dendritic islands, as observed from Raman spectroscopy.

Essays on cointegration analysis in the state space framework
Creators: name: Matuschek, Lukas
Publisher: name: TU Dortmund
Year: 2021
Subjects: subject: Cointegration
subject: State space systems
subject: 310
subject: Kointegrationsanalyse

description: Cointegration analysis is by now a standard tool in multivariate time series analysis with application ranging from economics to climate science. It was formalized by Soren Johansen and Katarina Juselius and their co-authors for VAR processes. This dissertation, consisting of three chapters corresponding to three articles written in collaboration with my co-authors Professor Dietmar Bauer, Patrick de Matos Ribeiro and Professor Martin Wagner, extends the cointegration theory to VARMA processes using a representation by state space systems. Chapter 1 focuses on theoretical results regarding the sets of transfer functions corresponding to VARMA systems with similar cointegrating properties, summarized in the so-called state space unit root structure. We develop and discuss different parameterizations for vector autoregressive moving average processes with arbitrary unit roots and (co)integration orders and discuss their topological properties. The general results are exemplified in detail for the empirically most relevant cases, the (multiple frequency or seasonal) I(1) and the I(2) case. In Chapter 2 we show that the Johansen framework for testing hypotheses on the cointegrating ranks and spaces for MFI(1) processes can be extended to the class of VARMA processes and introduce a state space error correction representation. The estimated cointegrating vectors are asymptotically mixed Gaussian and pseudo likelihood ratio tests for the cointegrating ranks have the same distributions under the null hypothesis in the VARMA case as in the VAR case. In a simulation study our tests outperform the tests by Johansen and Schaumburg in small samples. In Chapter 3 we develop estimation and inference techniques for I(2) cointegrated VARMA processes cast in state space format. We show consistency and derive the asymptotic distributions of estimators maximizing the Gaussian pseudo likelihood function. Furthermore, we discuss hypothesis tests for the state space unit root structure, leading to the well-known limiting distributions for VAR I(2) processes. Again, a small simulation study shows favorable results for small samples, with our test leading to better performance in determining these integer parameters.

description: The purpose of this study is to examine the teachers’ attitudes working in preschool education institutions that implement the practices of Montessori, Reggio Emilia, and the Ministry of National Education (MoNE) program. This study was carried out in descriptive research (survey) method. The study group was composed of 81 teachers working at Montessori, Reggio Emiliainspired and MoNE preschools in Kadıköy, Maltepe and Ataşehir districts of İstanbul. "Attitude Scale for Family Participation Studies for Teachers" was used as a data collection tool. In the analysis of the data, Kruskal Wallis and Mann Whitney U tests were used. As a result of data analysis; the attitude scores of the teachers working in the Reggio Emilia-inspired preschools were higher than the Montessori-inspired and MoNE preschools. In this context, it was detected that the Reggio Emilia approach is determinative on the teachers’ attitudes regarding the family participation practices in preshools included in the study. According to the findings of the research, it was concluded that family participation studies of different educational approaches should be considered and implemented as an integrated approach according to the needs in Turkey.

description: The Gamma Cephei planetary system is one of the most interesting systems due to several reasons: 1.) it is the first planet candidate detected by precise radial velocity (RV) measurements that was discussed in the literature (Campbell et al. 1988); 2.) it is a tight binary system with a ~ 20AU; and 3.) the planet host star is an evolved K-type star. In Hatzes et al. (2003) we confirmed the presence of the planetary companion with a minimum mass of 1.7 M_Jup at 2 AU. In this paper we present additional eight years of precise RV data from the Harlan J. Smith 2.7 m Telescope and its Tull Coude spectrograph at McDonald Observatory. The 900 d signal, that is interpreted as the presence of the giant planetary companion, is strongly confirmed by adding the new data. We present an updated orbital solution for the planet, which shows that the planet is slightly more massive and the orbit more circular than previous results have suggested. An intensive high-cadence week of RV observations in 2007 revealed that Gamma Cep A is a multi-periodic pulsator. We discuss this issue within the context of searching for additional planets in this system.

description: Systematic attack design is essential to understanding the vulnerabilities of cyber-physical systems (CPSs), to better design for resiliency. In particular, false data injection attacks (FDIAs) are well-known and have been shown to be capable of bypassing bad data detection (BDD) while causing targeted biases in resulting state estimates. However, their effectiveness against moving horizon estimators (MHE) is not well understood. In fact, this paper shows that conventional FDIAs are generally ineffective against MHE. One of the main reasons is that the moving window renders the static FDIA recursively infeasible. This paper proposes a new attack methodology, moving-horizon FDIA (MH-FDIA), by considering both the performance of historical attacks and the current system's status. Theoretical guarantees for successful attack generation and recursive feasibility are given. Numerical simulations on the IEEE-14 bus system further validate the theoretical claims and show that the proposed MH-FDIA outperforms state-of-the-art counterparts in both stealthiness and effectiveness. In addition, \textcolor{blue}{an experiment on} a path-tracking control system of an autonomous vehicle shows the feasibility of the MH-FDIA in real-world nonlinear systems.

description: We extend the relationship between mass and spin angular momentum, described by the bosonic spectrum of positive definite mass particles of the Majorana solution to the Dirac equation, to photons that acquire an effective Proca mass through the Anderson-Higgs mechanism when they propagate in a plasma. In an earlier paper we showed that if the plasma is structured, it can impart orbital angular momentum (OAM) to the photons that reduces the total Proca photon mass. Here we show, through a generalisation of Majorana's solution, that photons with OAM in a plasma cannot assume negative squared mass states. This means that there exist interesting analogies with Quantum Gravity or General Relativity models involving a modified action of the Lorentz group.

Half-quantum vortex generation in a two-component Bose-Einstein condensate by an oscillatory magnetic obstacle

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We numerically investigate the dynamics of vortex generation in a two-dimensional, twocomponent Bose-Einstein condensate subjected to an oscillatory magnetic obstacle. The obstacle creates both repulsive and attractive Gaussian potentials for the two symmetric spin-$\uparrow$ and $\downarrow$ components, respectively. We demonstrate that, as the oscillating frequency f increases, two distinct critical dynamics arise in the generation of half-quantum vortices (HQVs) with different spin circulations. Spin-$\uparrow$ vortices are nucleated directly from the moving obstacle at low f, while spin-$\downarrow$ vortices are created at high f by breaking a spin wave pulse in front of the obstacle. We find that vortex generation is suppressed for sufficiently weak obstacles, in agreement with recent experimental results by Kim et al. [Phys. Rev. Lett. 127, 095302 (2021)]. This suppression is caused by the finite sweeping distance of the oscillating obstacle and the reduction in friction in a supersonic regime. Finally, we show that the characteristic length scale of the HQV generation dynamics is determined by the spin healing length of the system.

Exploring the impact of physical activity- and nutrition-focused workplace wellness programs on employee quality of life
Creators: name: Lienhard, Katherine Elizabeth
Publisher: name: University of British Columbia
Year: 2020

description: Background: The majority of employed Canadians work forty hours per week, spending approximately seven hours per day at the workplace. Promoting and/or offering physical activity and proper nutrition at the workplace has been shown to increase activity and improve dietary choices both during and outside of work hours. Further, diet quality and activity levels together play major roles in a person's overall quality of life. Measuring quality of life, which includes physical, emotional, mental, and financial factors, is often conducted via survey, where results can be averaged to create an overall wellness score for each individual. Purpose: The aim of this study was to determine if nutrition and physical activity workplace wellness programs improve employee quality of life with the hypothesis that participants who participate will have higher overall wellness scores than those who do not. A systematic review with the same aim was also conducted. Methods: Twenty-eight employees at four Vancouver, BC companies with wellness programs were recruited to complete a survey. Data collection included the WellSuite® IV Health Risk Assessment for the Workforce (Non-U.S.) survey which contains 44 wellness-related questions. Employees who participated in their wellness program 25% or less of the time served as the control group. Data were described using descriptive statistics, contingency and frequency tables, ordinal logistic regression, one-way ANOVA, and independent samples T-tests. Results: The data suggests that those in the experimental group were more likely to have a higher Overall Wellness Score (p = 0.025), Fitness Score (p = 0.013), and to self-report higher life satisfaction and happiness than those in the control group. Nutrition Score increased with participation in the workplace wellness programs (p=0.035). Though limited by sample size and selection bias, this study supports the existing literature in the field and adds to the discussion on measuring quality of life outcomes of workplace wellness programs. Conclusion: The consistent and optimistic findings of this study are promising but inconclusive regarding the positive quality of life and overall health impact of workplace wellness programs that incorporate both PA and nutrition components. Future studies may benefit from aiming to limit confounding variables.

description: Whether polymorphic Human Leukocyte Antigen (HLA)-A, HLA-B and HLA-DRB1 alleles were associated with acute liver disease after hepatitis B virus (HBV) infections was investigated. In this study, from initially 100 participants in each group, HLA-A, HLA-B and HLA-DRB1 sequences were available from 86 acute hepatitis B (AHB) patients and from 84 HBV-resistant individuals (controls), using sequencing-based typing allele groups and alleles that exhibited differences in distribution between the case and control groups were subjected to chi-squared and logistic regression analyses to identify those associated with AHB. A dose response analysis was also performed on the effect of HLA-A*24:02 allele number on acute liver disease following HBV infection. The frequency distribution of HLA-B and HLA-DRB1 alleles in the control group were in Hardy-Weinberg Equilibrium (P > .05). HLA-A*24:02 (χ2 = 6.949, P = .008) occurred most frequently in the AHB and HLA-DRB1*12:02 (χ2 = 7.768, P = .005) in the control group. With adjustment for sex, the logistic regression model showed that the HLA-A*24:02 allele was significantly associated with AHB liver injury (P = .0326, OR = 2.270, 95% CI: 1.070–4.816), whereas the other HLA-A, HLA-B, and HLA-DRB1 alleles were not (P > .05). A linear response was observed for the association between HLA-A*24:02 allele number and acute liver disease after HBV infections (χ2 = 4.428, P = .025). The HLA-A*24:02 allele may influence the severity of the cellular response to HBV infection, increasing the elimination of HBV-infected hepatocytes. The HLA-A*24:02 allele may be a potential screening marker for identifying people or regional populations in China at higher risk of acute liver disease following HBV infection.

description: The purpose of this study is to examine the teachers’ attitudes working in preschool education institutions that implement the practices of Montessori, Reggio Emilia, and the Ministry of National Education (MoNE) program. This study was carried out in descriptive research (survey) method. The study group was composed of 81 teachers working at Montessori, Reggio Emiliainspired and MoNE preschools in Kadıköy, Maltepe and Ataşehir districts of İstanbul. "Attitude Scale for Family Participation Studies for Teachers" was used as a data collection tool. In the analysis of the data, Kruskal Wallis and Mann Whitney U tests were used. As a result of data analysis; the attitude scores of the teachers working in the Reggio Emilia-inspired preschools were higher than the Montessori-inspired and MoNE preschools. In this context, it was detected that the Reggio Emilia approach is determinative on the teachers’ attitudes regarding the family participation practices in preshools included in the study. According to the findings of the research, it was concluded that family participation studies of different educational approaches should be considered and implemented as an integrated approach according to the needs in Turkey.

description: Our focus is on the design and analysis of efficient Monte Carlo methods for computing tail probabilities for the suprema of Gaussian random fields, along with conditional expectations of functionals of the fields given the existence of excursions above high levels, b. Naïve Monte Carlo takes an exponential, in b, computational cost to estimate these probabilities and conditional expectations for a prescribed relative accuracy. In contrast, our Monte Carlo procedures achieve, at worst, polynomial complexity in b, assuming only that the mean and covariance functions are Hölder continuous. We also explain how to fine tune the construction of our procedures in the presence of additional regularity, such as homogeneity and smoothness, in order to further improve the efficiency.

Minimal weight in union-closed families

description: Let Omega be a finite set and let S be a set system on Omega. For x in Omega, we denote by d_{S}(x) the number of members of S containing x. A long-standing conjecture of Frankl states that if S is union-closed then d(x) \geq |S|/2 for some x in Omega. We consider a related question. Define the weight of S to be w(S)= \sum_{A in S} |A|. Suppose S is union-closed. How small can w(S) be? Reimer showed that w(S) \geq |S| \log_{2} |S| /2, and that this inequality is sharp. In this paper we show how his bound may be improved if we have some additional information about the domain Omega of S: if S separates the points of Omega, then w(S) \geq \binom{|Ω|}{2}. This is stronger than Reimer's Theorem when Omega > \sqrt{|S|\log_2 |S|}. In addition we construct a family of examples showing the combined bound on w(S) is tight except in the region |Ω|=Θ(\sqrt{|S|\log_2 |S|}), where it may be off by a multiplicative factor of 2. Our proof also gives a lower bound on the average degree: if S is a point-separating union-closed family, then the average degree over its domain is at least 1/2 \sqrt{|S| \log_2 |S|}+ O(1), and this is best possible except for a multiplicative factor of 2.

description: We use symbol correspondence and quantum normal form theory to develop a more general method for finding uniform asymptotic approximations. We then apply this method to derive a result we announced in an earlier paper, namely, the uniform approximation of the $6j$-symbol in terms of the rotation matrices. The derivation is based on the Stratonovich-Weyl symbol correspondence between matrix operators and functions on a spherical phase space. The resulting approximation depends on a canonical, or area preserving, map between two pairs of intersecting level sets on the spherical phase space.
