description: We report improved measurements of temperature anisotropies in the cosmic microwave background (CMB) radiation made with the Arcminute Cosmology Bolometer Array Receiver (ACBAR). In this paper, we use a new analysis technique and include 30% more data from the 2001 and 2002 observing seasons than the first release to derive a new set of band-power measurements with significantly smaller uncertainties. The planet-based calibration used previously has been replaced by comparing the flux of RCW38 as measured by ACBAR and BOOMERANG to transfer the WMAP-based BOOMERANG calibration to ACBAR. The resulting power spectrum is consistent with the theoretical predictions for a spatially flat, dark energy dominated LCDM cosmology including the effects of gravitational lensing. Despite the exponential damping on small angular scales, the primary CMB fluctuations are detected with a signal-to-noise ratio of greater than 4 up to multipoles of l=2000. This increase in the precision of the fine-scale CMB power spectrum leads to only a modest decrease in the uncertainties on the parameters of the standard cosmological model. At high angular resolution, secondary anisotropies are predicted to be a significant contribution to the measured anisotropy. A joint analysis of the ACBAR results at 150 GHz and the CBI results at 30 GHz in the multipole range 2000 < l < 3000 shows that the power, reported by CBI in excess of the predicted primary anisotropy, has a frequency spectrum consistent with the thermal Sunyaev-Zel'dovich effect and inconsistent with primary CMB. The results reported here are derived from a subset of the total ACBAR data set; the final ACBAR power spectrum at 150 GHz will include 3.7 times more effective integration time and 6.5 times more sky coverage than is used here.

description: We use Keck/HIRES spectra of 37 optically bright quasars at z=2-4 to study narrow absorption lines that are intrinsic to the quasars (intrinsic NALs, produced in gas that is physically associated with the quasar central engine). We identify 150 NAL systems, that contain 124 C IV, 12 N V, and 50 Si IV doublets, of which 18 are associated systems (within 5,000 km/s of the quasar redshift). We use partial coverage analysis to separate intrinsic NALs from NALs produced in cosmologically intervening structures. We find 39 candidate intrinsic systems, (28 reliable determinations and 11 that are possibly intrinsic). We estimate that 10-17% of C IV systems at blueshifts of 5,000-70,000 km/s relative to quasars are intrinsic. At least 32% of quasars contain one or more intrinsic C IV NALs. Considering N V and Si IV doublets showing partial coverage as well, at least 50% of quasars host intrinsic NALs. This result constrains the solid angle subtended by the absorbers to the background source(s). We identify two families of intrinsic NAL systems, those with strong N V absorption, and those with negligible absorption in N V, but with partial coverage in the C IV doublet. We discuss the idea that these two families represent different regions or conditions in accretion disk winds. Of the 26 intrinsic C IV NAL systems, 13 have detectable low-ionization absorption lines at similar velocities, suggesting that these are two-phase structures in the wind rather than absorbers in the host galaxy. We also compare possible models for quasar outflows, including radiatively accelerated disk-driven winds, magnetocentrifugally accelerated winds, and pressure-driven winds, and we discuss ways of distinguishing between these models observationally.

description: The present study investigates the image of the Latins as it is formed in the late byzantine society, during the rule of three byzantine emperors, Michael VIII, John V and John VIII Palaiologos, who raised the issue of the Union of the Churches, aiming at finding help from the West against a possible recapture of Constantinople by the Westerners and then the Ottoman expansion. The work examines the positive image of the Latins, as it is shaped by the circles of Byzantine society that desire the Union of Churches, the unionists, and the construction of the Latin alterity which is promoted by the anti-unionists. To examine this question, the formation of unionist and anti-unionist circles had to be analyzed, with the aim of showing the diversity of byzantine society by examining events that take place at different times and in different cultural contexts

description: It is well-known that there is no spherical/topologically spherical gravitational waves in vacuum space in general relativity. We show that a deviation from general relativity leads to exact vacuum spherical gravitational waves, no matter how tiny this deviation is. We also discuss the related topics, including Vaidya-like metric in $f(R)$ gravity. We demonstrate that the existence of spherical gravitational wave is a non perturbative property for gravities. We investigate energy carried by this nonperturbative wave. We first find the wave solution from investigations of Vaidya-like metric in $f(R)$ gravity, which has only one longitude polarization. We further extend it to a metric with two transverse polarizations by directly solving the field equation.

The accretion ratios in Seyfert 2 galaxies with and without hidden broad-line regions

description: Using a large sample of 90 Seyfert 2 galaxies (Sy2s) with spectropolarimetric observations, we tested the suggestion that the presence of hidden broad-line regions (HBLRs) in Sy2s is dependent upon the Eddington ratio. The stellar velocity dispersion and the extinction-corrected $\OIII$ luminosity are used to derive the mass of central super-massive black holes and the Eddington ratio. We found that: (1) below the Eddington ratio threshold of $10^{-1.37}$, all but one object belong to non-HBLRs Sy2s; while at higher Eddington ratio, there is no obvious discrimination in the Eddington ratio and black hole mass distributions for Sy2s with and without HBLRs; (2) nearly all low-luminosity Sy2s (e.g., $\LOIII < 10^{41} \ergs$) do not show HBLRs regardless of the column density of neutral hydrogen ($N_{\rm H}$); (3) for high-luminosity Sy2s, the possibility to detect HBLRs Sy2s is almost the same as that of non-HBLRs Sy2s; (4) when considering only Compton-thin Sy2s with higher $\OIII$ luminosity ($>10^{41} \ergs$), we find a very high detectability of HBLRs ,$\sim$ 85%. These results suggested that AGN luminosity plays a major role in not detecting HBLRs in low-luminosity Sy2s, while for high-luminosity Sy2s, the detectability of HBLRs depends not only upon the AGN activity, but also upon the torus obscuration.

description: The LHCb measurements of the $μ/ e$ ratio in $B \to K \ell \ell$ decays $(R_{K^{}})$ indicate a deficit with respect to the Standard Model prediction, supporting earlier hints of lepton universality violation observed in the $R_{K^{(*)}}$ ratio. Possible explanations of these $B$-physics anomalies include heavy $Z'$ bosons or scalar and vector leptoquarks mediating $b \to s μ^+ μ^- $. We note that a muon collider can directly measure this process via $μ^+ μ^- \to b \bar s$ and can shed light on the lepton non-universality scenario. Investigating currently discussed center-of-mass energies $\sqrt{s} = 3$, 6 and 10 TeV, we show that the parameter space of $Z'$ and leptoquark solutions to the $R_{K^{(*)}}$ anomalies can be mostly covered. Effective operators explaining the anomalies can be probed with the muon collider setup $\sqrt{s} = 6~{\rm TeV}$ and integrated luminosity $L = 4~{\rm ab^{-1}}$.

Fokker-Planck models and globular cluster evolution
Creators: name: Drukier, Gordon A.
Publisher: name: University of British Columbia
Year: 2008

description: Numerical models for globular cluster evolution using the orbit-averaged Fokker-Planck equation are compared with observations of the globular clusters M71 and NGC 6397. The first set of models studied includes a mass spectrum, a tidal boundary and allows for a central energy source from the formation, hardening and destruction of binaries formed in three-body interactions. These models are compared to star-count mass functions and surface density profiles for M71. It is possible to reproduce the tidal boundary and degree of mass segregation using these models but the central density profiles of the fitted models are much steeper than is observed. On the basis of the degree of mass segregation and the short relaxation time, M71 is dynamically a highly evolved object, but the surface density profile contradicts this. Several modifications of the model are considered to resolve this difficulty, and an additional energy source, which does not require extreme densities to operate, appears to be required. New observations of the cluster NGC 6397 are presented. This cluster is presently at a similar position in the galaxy as M71, and has a similar mass and mass function, but is much more centrally concentrated. NGC 6397 is a low metallicity cluster with halo kinematics, in contrast to the metal-rich disk cluster M71. The observations have been reduced to give a surface density profile, and mass functions at two distances from the cluster centre. The surface density profile is fit by a power-law with slope —0.8 in the central arc minute. The mass functions give some evidence for mass segregation, but the low signal-to-noise of the outer mass function limits the significance of this observation. A second set of models, augmented to include the effects of mass loss due to stellar evolution, are used to find matches for the observations of M71 and NGC 6397. A diagram showing the evolution with time of the amount of mass segregation and the half-density radius is shown to be useful in identifying good candidate models. Stellar evolution appears not to solve the problem ofM71 as no satisfactorily matching model has been found. Possible solutions to this problem are discussed. The observations of NGC 6397 can be reproduced by the models and the best such model is described. This model has an initial mass function with a Salpeter-like slope and is undergoing core-collapse. This demonstrates that a numerical model based on the orbit-averaged Fokker-Planck equation, and including an evolving mass spectrum, a tidal boundary and the binary energy source, is a useful model for the dynamical evolution of some globular clusters.
Data-driven distributionally robust MPC for constrained stochastic systems

Publisher: name: arXiv
Year: 2021
Subjects: subject: Systems and Control (eess.SY)

description: In this paper we introduce a novel approach to distributionally robust optimal control that supports online learning of the ambiguity set, while guaranteeing recursive feasibility. We introduce conic representable risk, which is useful to derive tractable reformulations of distributionally robust optimization problems. Specifically, to illustrate the techniques introduced, we utilize risk measures constructed based on data-driven ambiguity sets, constraining the second moment of the random disturbance. In the optimal control setting, such moment-based risk measures lead to tractable optimal controllers when combined with affine disturbance feedback. Assumptions on the constraints are given that guarantee recursive feasibility. The resulting control scheme acts as a robust controller when little data is available and converges to the certainty equivalent controller when a large sample count implies high confidence in the estimated second moment. This is illustrated in a numerical experiment.

A novel $W^{1,\infty}$ approach to shape optimisation with Lipschitz domains

Publisher: name: arXiv

description: This article introduces a novel method for the implementation of shape optimisation with Lipschitz domains. We propose to use the shape derivative to determine deformation fields which represent steepest descent directions of the shape functional in the $W^{1,\infty}-$ topology. The idea of our approach is demonstrated for shape optimisation of $n$-dimensional star-shaped domains, which we represent as functions defined on the unit $(n-1)$-sphere. In this setting we provide the specific form of the shape derivative and prove the existence of solutions to the underlying shape optimisation problem. Moreover, we show the existence of a direction of steepest descent in the $W^{1,\infty}-$ topology. We also note that shape optimisation in this context is closely related to the $\infty-$Laplacian, and to optimal transport, where we highlight the latter in the numerics section. We present several numerical experiments in two dimensions illustrating that our approach seems to be superior over a widely used Hilbert space method in the considered examples, in particular in developing optimised shapes with corners.

description: This postgraduate thesis entitled "The transfer of policy from the OECD to Greece through the Arseni reform and the implementation of similar policies internationally in the 1990s" was prepared by Magda Hatzistrati, a student of the Postgraduate Program "Sciences of Education" "Educational Policy" of the Department of Preschool Education and Training, of the Pedagogical School of the Aristotle University of Thessaloniki, under the supervision of Professor Konstantinos Tsioumis and was completed in May 2020. The central theme of the work is the comparative view of the transfer of OECD policies to the educational policy of Greece, Egypt, Finland and Estonia, as members of the International Organization in the 1990s. With the help of the comparative-historical analysis, the state educational jurisprudences are investigated in relation to the proposals of the OECD for the consolidation of the Greek educational system of the Member States, arrested and more targeted than the Greek one. The project is based on the scientific fields of the History of Education, Educational Policy and Sociology. Finally, the historical evidence is drawn from the OECD Reports and the educational legislation of the Member States.

description: We consider the astrophysical implications of the diffusion equation solution for Ultra-High Energy Cosmic Rays (UHECR) in the expanding universe, obtained in paper I (V.Berezinsky & A.Gazizov, ApJ 643 (2006) 8). The UHECR spectra are calculated in a model with sources located in vertices of the cubic grid with a linear constant (source separation) d. The calculations are performed for various magnetic field configurations (B_c,l_c), where l_c is the basic scale of the turbulence and B_c is the coherent magnetic field on this scale. The main purpose of these calculations is to demonstrate the validity of the solution obtained in paper I and to compare this solution with the Syrovatsky solution used in previous works. The Syrovatsky solution must be necessarily embedded in the static cosmological model. The formal comparison of the two solutions with all parameters being fixed identically reveals the appreciable discrepancies between two spectra. These discrepancies are less if in both models the different sets of the best-fit parameters are used.

description: Spatial-temporal forecasting has attracted tremendous attention in a wide range of applications, and traffic flow prediction is a canonical and typical example. The complex and long-range spatial-temporal correlations of traffic flow bring it to a most intractable challenge. Existing works typically utilize shallow graph convolution networks (GNNs) and temporal extracting modules to model spatial and temporal dependencies respectively. However, the representation ability of such models is limited due to: (1) shallow GNNs are incapable to capture long-range spatial correlations, (2) only spatial connections are considered and a mass of semantic connections are ignored, which are of great importance for a comprehensive understanding of traffic networks. To this end, we propose Spatial-Temporal Graph Ordinary Differential Equation Networks (STGODE). Specifically, we capture spatial-temporal dynamics through a tensor-based ordinary differential equation (ODE), as a result, deeper networks can be constructed and spatial-temporal features are utilized synchronously. To understand the network more comprehensively, semantical adjacency matrix is considered in our model, and a well-design temporal dialated convolution structure is used to capture long term temporal dependencies. We evaluate our model on multiple real-world traffic datasets and superior performance is achieved over state-of-the-art baselines.

description: We show that if the visible universe is a membrane embedded in a higher-dimensional space, particles in uniform motion radiate gravitational waves because of spacetime lumpiness. This phenomenon is analogous to the electromagnetic diffraction radiation of a charge moving near to a metallic grating. In the gravitational case, the role of the metallic grating is played by the inhomogeneities of the extra-dimensional space, such as a hidden brane. We derive a general formula for gravitational diffraction radiation and apply it to a higher-dimensional scenario with flat compact extra dimensions. Gravitational diffraction radiation may carry away a significant portion of the particle's initial energy. This allows to set stringent limits on the scale of brane perturbations. Physical effects of gravitational diffraction radiation are briefly discussed.

We obtain a lower bound on the speed dependent on the cutoff, and for which the two leading order terms correspond to the Brunet Derrida expression. To do so we cast a known variational principle for the speed of propagation of fronts in new variables which makes it more suitable for applications.

description: The single-layered ruthenate Sr$_2$RuO$_4$ is one of the most enigmatic unconventional superconductors. While for many years it was thought to be the best candidate for a chiral $p$-wave superconducting ground state, desirable for topological quantum computations, recent experiments suggest a singlet state, ruling out the original $p$-wave scenario. The superconductivity as well as the properties of the multi-layered compounds of the ruthenate perovskites are strongly influenced by a van Hove singularity in proximity of the Fermi energy. Tiny structural distortions move the van Hove singularity across the Fermi energy with dramatic consequences for the physical properties. Here, we determine the electronic structure of the van Hove singularity in the surface layer of Sr$_2$RuO$_4$ by quasiparticle interference imaging. We trace its dispersion and demonstrate from a model calculation accounting for the full vacuum overlap of the wave functions that its detection is facilitated through the octahedral rotations in the surface layer.

description: We solve the problem of coherent Mikheyev-Smirnov-Wolfenstein (MSW) resonant active-to-sterile neutrino flavor conversion driven by an initial lepton number in the early universe. We find incomplete destruction of lepton number in this process and a sterile neutrino energy distribution with a distinctive cusp and high energy tail. These features imply alteration of the non-zero lepton number primordial nucleosynthesis paradigm when there exist sterile neutrinos with rest masses ~ 1 eV. This could result in better light element probes of (constraints on) these particles.

description: Optical levitation of mechanical oscillators has been suggested as a promising way to decouple the environmental noise and increase the mechanical quality factor. Here, we investigate the dynamics of a free-standing mirror acting as the top reflector of a vertical optical cavity, designed as a testbed for a tripod cavity optical levitation setup. To reach the regime of levitation for a milligram-scale mirror, the optical intensity of the intracavity optical field approaches 3 MW cm$^{-2}$. We identify three distinct optomechanical effects: excitation of acoustic vibrations, expansion due to photothermal absorption, and partial lift-off of the mirror due to radiation pressure force. These effects are intercoupled via the intracavity optical field and induce complex system dynamics inclusive of high-order sideband generation, optical bistability, parametric amplification, and the optical spring effect. We modify the response of the mirror with active feedback control to improve the overall stability of the system.

description: The Hamiltonian structure of general relativity provides a natural canonical measure on the space of all classical universes, i.e., the multiverse. We review this construction and show how one can visualize the measure in terms of a "magnetic flux" of solutions through phase space. Previous studies identified a divergence in the measure, which we observe to be due to the dilatation invariance of flat FRW universes. We show that the divergence is removed if we identify universes which are so flat they cannot be observationally distinguished. The resulting measure is independent of time and of the choice of coordinates on the space of fields. We further show that, for some quantities of interest, the measure is very insensitive to the details of how the identification is made. One such quantity is the probability of inflation in simple scalar field models. We find that, according to our implementation of the canonical measure, the probability for N e-folds of inflation in single-field, slow-roll models is suppressed by of order exp(-3N) and we discuss the implications of this result.

description: We study neutrino and antineutrino emission from the direct Urca process in neutron-star matter in the presence of strong magnetic fields. We calculate the neutrino emissivity of the direct Urca process, whereby a neutron converts to a proton, an electron and an antineutrino, or a proton-electron pair converts to a neutron-neutrino pair. We solve exact wave functions for protons and electrons in the states described with Landau levels. We find that the direct Urca process can satisfy the kinematic constraints even in density regions where this process could not normally occur in the absence of a magnetic field.

A Game-Theoretic Analysis of Cross-Ledger Swaps with Packetized Payments

description: We propose a game-theoretic framework to study the outcomes of packetized payments, a cross-ledger transaction protocol, with strategic and possibly malicious agents. We derive the transaction failure rate and demonstrate that without disciplinary mechanisms, packetized payments are likely to be incomplete. Our analysis suggests that collateral deposits can prevent malicious agents from taking advantage of the protocol. We further infer that the deposit amount should depend on the underlying asset price volatility or that it should be dynamically adjusted as the price changes.

Theory of the general orientation dependence of ²H NMR spin-lattice relaxation and experiments on model membranes
Creators: name: Morrison, Clare
Publisher: name: University of British Columbia
Year: 2008

description: Deuterium nuclear magnetic resonance (NMR) spin-lattice relaxation was used to explore molecular motions. A general theory of relaxation rates was developed. Motions fast on the NMR timescale were investigated, model-independently, in the acyl chain and headgroup of phospholipids in the liquid crystalline phase. The general orientation dependence of spin-lattice relaxation of spin-1 nuclei interacting via fluctuating quadrupolar interactions was considered within the Redfield approximation. The NMR spectrum is characterized in terms of the principal axis co-ordinate system (PACS) of the time-averaged electric field gradient tensor. The most general form of the relaxation rates may be written in terms of the polar coordinates(/3, a) of the magnetic field in the PACS. It involves a sum of spherical harmonics up to order four: 1P = E E aoT(,3, a) ,p even Tz P=0 q=,-p where T, represents T1z, TiQ and T2 and the aP9 depend on reduced spectral densities and spherical order parameters which are independent of the orientation of the magnetic field. Tiz and T1Q relaxation times were measured at every carbon position on a perdeuterated palmitoyl acyl chain on 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). The order parameter S20 (=SCD), was determined, model-independently, to be negative. The rotational diffusion model as formulated by Schindler and Seelig (Biochem.14:2283) is incorrect based on the range of experimentally acceptable S40. The fluctuations of the CD bond were successfully modelled as a uniform distribution. There is a spectrum of correlation times contributing to the reduced spectral densities at 46.2MHz. The addition of 20 mol% cholesterol to POPC primarily affects the trans-gaucheisomerization rate of the first twelve carbon positions on the palmitoyl chain. The rotational diffusion constant is not significantly affected. The temperature dependence of the pure and mixed systems confirm our conclusions. The order parameters S20 of the alpha and beta position of the head group ofdipalmitoyl-sn-glycerol-3-phosphocholine (DPPC) were determined to be negative. Due to the small orientation dependence of Tiz and T1Q, S40 was determined model-independently. The fluctuations of the CD bond were modelled as a uniform distribution. A T1z field-dependent study indicated at least two correlation times, a short and intermediate or long, were necessary. Distributions of correlation times fit equally well indicating a complex array of motions. A method is presented for measuring lateral diffusion of phospholipids along curved surfaces by measuring the transfer of magnetization due to diffusion via spin-lattice relaxation techniques. Experiments were performed on DPPC and a diffusion constant of 4 x 10-12m2s-1 was determined. Polycrystalline hex methylbenzene was investigated as an example of non-axially symmetric motion (17=0.1). A three motion model was evaluated using the general theory and Tlz and T1c2 relaxation spectra.

description: Courant algebroids were invented in 1997 by Liu, Weinstein and Xu as the appropriate notion for the (Drinfeld) double of a Lie bialgebroid. In that thesis we investigate Courant algebroids and understand that they are an example of L-infinity algebras. Then, we interpret the double of a Lie bialgebroid as a supermanifold equipped with a homological vector field. Finally, we recover, using the glossary of graded manifolds, classical geometrical structures , as that of Courant algebroids, in a more clear and elegant manner.

Σε αυτή την διπλωματική ερευνούμε τα αλγεβροειδή Courant και αντιλαμβανόματε ότι είναι ένα παράδειγμα L-άπειρων αλγεβρών. Στην συνέχεια, ερμηνεύουμε το διπλό ενός δι-αλγεβροειδούς Lie ως μια σούπερ-πολλαπλότητα εφοδιασμένη με ένα ομολογικό διανυσματικό πεδίο. Τέλος, χρησιμοποιώντας την γλώσσα των βαθμωτών πολλαπλοτήτων ανακτούμε κλασσικές γεωμετρικές δομές, όπως αυτή των αλγεβροειδών Courant, με έναν πιο σαφή και κομψό τρόπο.

description: Quantum phase is not a direct observable and is usually determined by interferometric methods. We present a method to map complete electron wave functions, including internal quantum phase information, from measured single-state probability densities. We harness the mathematical discovery of drum-like manifolds bearing different shapes but identical resonances, and construct quantum isospectral nanostructures possessing matching electronic structure but divergent physical structure. Quantum measurement (scanning tunneling microscopy) of these "quantum drums" [degenerate two-dimensional electron states on the Cu(111) surface confined by individually positioned CO molecules] reveals that isospectrality provides an extra topological degree of freedom enabling robust quantum state transplantation and phase extraction.

description: This paper pushes the envelope on decomposing camouflaged regions in an image into meaningful components, namely, camouflaged instances. To promote the new task of camouflaged instance segmentation of in-the-wild images, we introduce a dataset, dubbed CAMO++, that extends our preliminary CAMO dataset (camouflaged object segmentation) in terms of quantity and diversity. The new dataset substantially increases the number of images with hierarchical pixel-wise ground truths. We also provide a benchmark suite for the task of camouflaged instance segmentation. In particular, we present an extensive evaluation of state-of-the-art instance segmentation methods on our newly constructed CAMO++ dataset in various scenarios. We also present a camouflage fusion learning (CFL) framework for camouflaged instance segmentation to further improve the performance of state-of-the-art methods. The dataset, model, evaluation suite, and benchmark will be made publicly available on our project page: https://sites.google.com/view/ltnghia/research/camo_plus_plus
