Halos and voids in a multifractal model of cosmic structure

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: On the one hand, the large scale structure of matter is arguably scale invariant, and, on the other hand, halos and voids are recognized as prominent features of that structure. To unify both approaches, we propose to model the dark matter distribution as a set of fractal distributions of halos of different kinds. This model relies on the concept of multifractal as the most general scaling distribution and on a plausible notion of halo as a singular mass concentration in a multifractal. Voids arise as complementary to halos, namely, as formed by regular mass depletions. To provide halos with definite size and masses, we coarse-grain the dark matter distribution, using the length given by the lower cutoff to scaling. This allows us to relate the halo mass function to the multifractal spectrum. Hence, we find that a log-normal model of the mass distribution nicely fits in this picture and, moreover, the Press-Schechter mass function can be recovered as a bifractal limit. To support our model of fractal distributions of halos, we perform a numerical study of the distribution produced in cosmological N-body simulations. In the Virgo L-CDM GIF2 simulation, we indeed find fractal distributions of halos with various dimensions and a halo mass function of bifractal type. However, this mass function is not of Press-Schechter's type, and we interprete it instead as caused by the undersampling of the distribution at the scale of halos, due to discretization.

description: A Dirac electron field is quantized in the background of a Dirac magnetic monopole, and the phenomenon of induced quantum numbers in this system is analyzed. We show that, in addition to electric charge, also squares of orbital angular momentum, spin, and total angular momentum are induced. The functional dependence of these quantities on the temperature and the CP-violating vacuum angle is determined. Thermal quadratic fluctuations of charge and squared total angular momentum, as well as the correlation between them and their correlations with squared orbital angular momentum and squared spin, are examined. We find the conditions when charge and squared total angular momentum at zero temperature are sharp quantum observables rather than mere quantum averages.

Generation of 1880

description: Το περιοδικό "Εστία"(1876-1895) υπήρξε το πιο αξιόλογο περιοδικό στα τέλη του 19ου αιώνα, αντιπροσωπευτικό όργανο της γενιάς του 1880. Το περιοδικό κυκλοφόρησε ως οικογενειακό-φιλολογικό περιοδικό, αλλά βαθμιαία εξελίχθηκε σε λογοτεχνικό. Η διδ. διατριβή παρακολουθεί την εξέλιξη στο χώρο της ποίησης, δηλ. τον τρόπο προβολής της στο περιοδικό, τις εκάστοτε επιλογές, τις φάσεις αλλαγών, μεταρρυθμίσεων και καινοτομιών, που έχουν σχέση με την ποίηση και την κριτική της. Η παρουσία της ποίησης είναι μικρή, αλλά συνεχώς αυξάνεται. Το περιοδικό, συντηρητικό και επιφυλακτικό αρχικά, κατορθώνει και αντανακλά, αργότερα, την ποιητική έκφραση της εποχής, μέσα από τα ποιητικά και κριτικά κείμενα, που δημοσιεύει
description: "Estia" was the most important periodical in the last quarter of 19th century, representative of the generation of 1880. The thesis describes how poetry has been appeared into "Estia"'s pages. It analyzes the changes, the innovations and the reformations related poetry and its criticism."Estia" was conservative and reserved at the beginning, but afterwards it managed to reflect the poetic expression of the time, through its poetic texts and critical articles

description: Shear viscosity (eta) of QCD in the hadronic phase is computed by the coupled Boltzmann equations of pions and nucleons in low temperatures and low baryon number densities. The eta to entropy density ratio eta/s maps out the nuclear gas-liquid phase transition by forming a valley tracing the phase transition line in the temperature-chemical potential plane. When the phase transition turns into a crossover, the eta/s valley gradually disappears. We suspect the general feature for a first-order phase transition is that eta/s has a discontinuity in the bottom of the eta/s valley. The discontinuity coincides with the phase transition line and ends at the critical point. Beyond the critical point, a smooth eta/s valley is seen. However, the valley could disappear further away from the critical point. The eta/s measurements might provide an alternative to identify the critical points.

description: In this paper, the $P-V$ criticality and Joule-Thomson Expansion of Hayward-AdS black holes in 4D Einstein-Gauss-Bonnet gravity are studied in the extended phase space. We find the black hole always exhibits a phase transition similar to that of the Van der Waals system for any arbitrary positive parameters $α$ and $g$. We also study the dependence of $α$ and $g$ on the inversion curves and plot the inversion and isenthalpic curves in the $T-P$ plane, which can determine the cooling-heating regions.

description: Our research concerns the literary-aescthetic and not the realistic dimensions of the "Meteorological" Georgics. Our methodology consists mainly in the comparison between(ancient Greek and Latin)passages which exhibit obvious realistic/factual-technical analogies(i.e. similar way of predicting a weather phenomenon). The present thesis consists of four chapters, each of them treating the signs of weather prediction of a specific phenomenon. Each chapter is divided into sections which are defined by the vehicles/instruments of prediction. The concluding paragraphs of each chapter include partial conclusions which comprise contributory parts of the following general ascertainments : although the subject-prediction of weather phenomena-is not prone to poetic exploitation, Virgil exceeds the frame of the collection and of the description of weather information. Virgil's passages are characterized by poetic exaltations : contrasts of colours, alternations of images, scales of sounds, mythological allysions, elements which are almost non-existent in his poetic model, Aratus' Phenomena. Meteorological information is undermined in favour of expressional variation. The Roman poet borrows from his sources those elements which provide him with stimuli for delicate poetic manipulation. The meteorological part of Vergil's Georgics exhibits the strong influence of Alexandrian Hellenistic tradition

description: The currentsystematic review aimed to collect and analyze the comprehensive evidenceregarding Polymerase Spiral Reaction (PSR) and to estimate its diagnosticperformance and usefulness as a point-of-care (PoC) assay. Literaturewas retrieved systematically from 2015 to 2023 from PubMed and Scopus. Studieswere screened and selected against pre-determined inclusion and exclusioncriteria. Quality assessment and risk of bias were critiqued using QUADAS-2. Asystematic, qualitative narrative synthesis was employed to synthesize the data.  11 studies wereselected for the systematic review, testing diseases in humans utilizing PSR.Only 2 studies clinically validated the test with a sample size > 150. 5studies were of poor quality; 3 studies were of moderate quality and 3 studieswere deemed to be of high quality. 3 studies quantified the diagnostic throughputand reported clinical sensitivity and specificity of PSR to be > 92% and ~ 100% respectively. Polymerase spiralreaction promises to be an optimistic isothermal assay; however, a hugeresearch gap can be attributed to the lack of statistical and clinical evidenceto validate the assay. Adequate research, focused on optimization, coupled withstatistical and clinical validation, can help in estimating its true diagnosticpotential and applicability.

description: Integrated Gradients (IG) is a commonly used feature attribution method for deep neural networks. While IG has many desirable properties, the method often produces spurious/noisy pixel attributions in regions that are not related to the predicted class when applied to visual models. While this has been previously noted, most existing solutions are aimed at addressing the symptoms by explicitly reducing the noise in the resulting attributions. In this work, we show that one of the causes of the problem is the accumulation of noise along the IG path. To minimize the effect of this source of noise, we propose adapting the attribution path itself -- conditioning the path not just on the image but also on the model being explained. We introduce Adaptive Path Methods (APMs) as a generalization of path methods, and Guided IG as a specific instance of an APM. Empirically, Guided IG creates saliency maps better aligned with the model's prediction and the input image that is being explained. We show through qualitative and quantitative experiments that Guided IG outperforms other, related methods in nearly every experiment.

We use the zeta function formalism, and the results agree with what one would obtain using the angular momentum cutoff method based on radial WKB. The final expression is numerically equal to an alternative expression derived in a Feynman diagrammatic approach, but is considerably simpler.

Equivalence transformations for classes of differential equations
Creators: name: Lisle, Ian
Publisher: name: University of British Columbia
Year: 2008

description: We consider classes C of differential equations characterized by the presence of arbitrary elements, that is, arbitrary functions or constants. Based on an idea of Ovsiannikov, we develop a systematic theory of equivalence transformations, that is, point changes of variables which map every equation in C to another equation in C. Examples of nontrivial groups of equivalence transformations are found for some linear wave and nonlinear diffusion convection systems, and used to clarify some previously known results. We show how equivalence transformations may be inherited as symmetries of equations in C, leading to a partial symmetry classification for the class C. New symmetry results for a potential system form of the nonlinear diffusion convection equation are derived by this procedure. Finally we show how to use equivalence group information to facilitate complete symmetry classification for a class of differential equations. The method relies on the geometric concept of a moving frame, that is, an arbitrary (possibly noncommuting) basis for differential operators on the space of independent and dependent variables. We show how to choose a frame which is invariant under the action of the equivalence group, and how to rewrite the determining equations for symmetries in terms of this frame. A symmetry classification algorithm due to Reid is modified to deal with the case of noncommuting operators. The result is an algorithm which combines features of Reid's classification algorithm and Cartan's equivalence method. The method is applied to the potential diffusion convection example, and yields a complete symmetry classification in a particularly elegant form.

description: A multi-imaging strategy is proposed and experimentally tested to improve the accuracy of photon counting with an electron multiplying charge-coupled device (EMCCD), by taking into account the random nature of its on-chip gain and the possibility of multiple photo-detection events on one pixel. This strategy is based on Bayesian estimation on each image, with a priori information given by the sum of the images. The method works even for images with large dynamic range, with more improvement in the low light level areas. In these areas, two thirds of the variance added by the EMCCD in a conventional imaging mode are removed, making the physical photon noise predominant in the detected image.

description: The Moon provides a huge effective detector volume for ultrahigh energy cosmic neutrinos, which generate coherent radio pulses in the lunar surface layer due to the Askaryan effect. In light of presently considered lunar missions, we propose radio measurements from a Moon-orbiting satellite. First systematic Monte Carlo simulations demonstrate the detectability of Askaryan pulses from neutrinos with energies above 10^{20} eV, i.e. near and above the interesting GZK limit, at the very low fluxes predicted in different scenarios.

description: This work is concerned with practical stabilization of nonlinear systems by means of inf-convolution-based sample-and-hold control. It is a fairly general stabilization technique based on a generic non-smooth control Lyapunov function (CLF) and robust to actuator uncertainty, measurement noise, etc. The stabilization technique itself involves computation of descent directions of the CLF. It turns out that non-exact realization of this computation leads not just to a quantitative, but also qualitative obstruction in the sense that the result of the computation might fail to be a descent direction altogether and there is also no straightforward way to relate it to a descent direction. Disturbance, primarily measurement noise, complicate the described issue even more. This work suggests a modified inf-convolution-based control that is robust w. r. t. system and measurement noise, as well as computational uncertainty. The assumptions on the CLF are mild, as, e. g., any piece-wise smooth function, which often results from a numerical LF/CLF construction, satisfies them. A computational study with a three-wheel robot with dynamical steering and throttle under various tolerances w. r. t. computational uncertainty demonstrates the relevance of the addressed issue and the necessity of modifying the used stabilization technique. Similar analyses may be extended to other methods which involve optimization, such as Dini aiming or steepest descent.

description: Diese Arbeit befasst sich mit dem Leben und demm Schrifttum des Patriachen Philotheos Kokkinos. Er wurde in Thessaloniki gegen 1295-97 geboren, wo er die Schule des Thomas Magistros besuchte. Er wurde Monch im athonischen Kloster Batopedi(1328). In den jahren 1331-1347 treffen wir ihn als Abt des Klosters Megiste Lawra und als einen heftigen Verteidiger des Gregorios Palamas und der Hesychasten. In den Jahren 1341-1342 ist er Abt Klosters Philokallou in Thessaloniki. Im jahre 1347 wurde er zum Metropoliten von Heraklia(Thrakien) gewahlt, und spater zum Patriarch von Konstantinopel(Erste Amtsperiode : September 1353-November 1354, zweite Amtsperiode : 8 Oktober 1364-August 1376). Zu seiner Zeit wurde der Hesychasmus als ofizielle dogmatische Lehre der Orthodoxen Kirche annerkant. Seine Kirchenolitik ist ein Versuch zur Verbreitung des Hesychasmus in der Slawenwelt(Russland, Serbien, Bulgarien) und ist allerdings unabhangig von der kaiserlichen Politik. Der literarische Nachlass des Philopheos Kokkinos umfasste Dogmatik und Polemik, Hagiographie, Exegese, Homeletik, liturgische Dichtung, Katonisches Recht und andere. Charakteristikum seiner Theologie ist die Lehre der ungeschaffenen gottlichen Kraft(Enegeia)

description: We present medium-resolution VLT/FORS2 spectroscopy of six cataclysmic variables discovered by the Sloan Digital Sky Survey. We determine orbital periods for SDSS J023322.61+005059.5 (96.08 +/- 0.09 min), SDSS J091127.36+084140.7 (295.74 +/- 0.22 min), SDSS J103533.02+055158.3 (82.10 +/- 0.09 min), and SDSS J121607.03+052013.9 (most likely 98.82 +/- 0.16 min, but the one-day aliases at 92 min and 107 min are also possible) using radial velocities measured from their H_alpha and H_beta emission lines. Three of the four orbital periods measured here are close to the observed 75--80 min minimum period for cataclysmic variables, indicating that the properties of the population of these objects discovered by the SDSS are substantially different to those of the cataclysmic variables found by other means. Additional photometry of SDSS J023322.61+005059.5 reveals a periodicity of approximately 60 min which we interpret as the spin period of the white dwarf, suggesting that this system is an intermediate polar with a low accretion rate. SDSS J103533.02+055158.3 has a period right at the observed minimum value, a spectrum dominated by the cool white dwarf primary star and exhibits deep eclipses, so is an excellent candidate for an accurate determination of the parameters of the system. The spectroscopic orbit of SDSS J121607.03+052013.9 has a velocity amplitude of only 13.8 +/- 1.6 km/s, implying that this system has an extreme mass ratio. From several physical constraints we find that this object must contain either a high-mass white dwarf or a brown-dwarf-mass secondary component or both.

description: Archival X-ray observations of EF Eridani obtained in a low state revealed distinct X-ray detections at a luminosity L_X ~ 2 10^{29} erg/s, three orders of magnitude below its high state value. The plasma temperature was found to be as low as $kT \loa 2$ keV, a factor 10 below the high state. The X-ray/UV/IR spectral energy distribution suggests faint residual accretion rather than coronal emission as being responsible for the low-state X-ray emission. EF Eri thus showed a clear transition from being shock-dominated in the high state to be cyclotron-dominated in the low state. From the optical/UV spectral energy distribution we re-determine the photospheric temperature of the white dwarf to \~10000K. Contrary to earlier claims, WD model atmospheres produce sufficient UV flux to reproduce the published GALEX flux and orbital modulation.

description: High-resolution gamma-ray spectroscopy of 18N is performed with the Advanced GAmma Tracking Array AGATA, following deep-inelastic processes induced by an 18O beam on a 181Ta target. Six states are newly identified, which together with the three known excitations exhaust all negative-parity excited states expected in 18N below the neutron threshold. Spin and parities are proposed for all located states on the basis of decay branchings and comparison with large-scale shell-model calculations performed in the p-sd space, with the YSOX interaction. Of particular interest is the location of the 0^-_1 and 1^-_2 excitations, which provide strong constrains for cross-shell p-sd matrix elements based on realistic interactions, and help to simultaneously reproduce the ground and first-excited states in 16N and 18N, for the first time. Understanding the 18N structure may also have significant impact on neutron-capture cross-section calculations in r-process modeling including light neutron-rich nuclei.

description: This thesis examines the architectural sculpture from Thessaly and Phthiotis. It aims investigate the relations between these two territories and their neighborhood (Constantinople and its zone of influence on the hand and southern greece on the other), to examine the contribution of the local workshops in the manufacture of local variants and determine a relative chronological classification of the sculptures based on the development of their form and decoration. The research covers the early christian times and the oeriod known as :The Dark Ages". The examination has been reduced to the decorative sculpture coming grom the supportive structure of the buildings, that is to say, column, pierand pilaster capitals, imposts and cornices. The dissertation consists of two parts in separated volumes. The first volume includes the analyses of the matieral and it is subdivided in 7 chapters. The first chapter discusses the historical and archaeological evidence concerning the area covers by the study. The five following chapters concentrate on the analysis of the architectural sculpture. In the last chapter are assembled the conclusions of the research. The second volume includes a descriptive catalogue of the material, illustrations of the sculptures under examination, maps, diagrams, as well as illustrations of the comparative material used for the annotations

description: We study a quantum dot strongly coupled to a single high-finesse optical microcavity mode. We use a rotating wave approximation method, commonly used in ion-laser interactions, tegether with the Lamb-Dicke approximation to obtain an analytic solution of this problem. The decay of Rabi oscillations because of the electron-phonon coupling are studied at arbitrary temperature and analytical expressions for the collapse and revival times are presented. Analyses without the rotating wave approximation are presented by means of investigating the energy spectrum.

description: By a suitable transformation, we present the $(n+1)$-dimensional charged rotating solutions of Gauss-Bonnet gravity with a complete set of allowed rotation parameters which are real in the whole spacetime. We show that these charged rotating solutions present black hole solutions with two inner and outer event horizons, extreme black holes or naked singularities provided the parameters of the solutions are chosen suitable. Using the surface terms that make the action well-defined for Gauss-Bonnet gravity and the counterterm method for eliminating the divergences in action, we compute finite action of the solutions. We compute the conserved and thermodynamical quantities through the use of free energy and the counterterm method, and find that the two methods give the same results. We also find that these quantities satisfy the first law of thermodynamics. Finally, we perform a stability analysis by computing the heat capacity and the determinant of Hessian matrix of mass with respect to its thermodynamic variables in both the canonical and the grand-canonical ensembles, and show that the system is thermally stable. This is commensurate with the fact that there is no Hawking-Page phase transition for black objects with zero curvature horizon.

description: Organisations are currently lacking in developing and implementing business systems in meaningful ways to motivate and engage their staff. This is particularly salient as the average employee spends eleven cumulative years of their life at work, however less than one third of the workforce are actually engaged in their duties throughout their career. Such low levels of engagement are particularly prominent with younger employees, referred to as Generation Y (GenY), who are the least engaged of all groups at work. However, they will dedicate around five cumulative years of their life immersed playing video games such as Clash of Clans, whether for social, competitive, extrinsic, or intrinsic motivational factors. Using behavioural concepts derived from video games, and applying game design elements in business systems to motivate employees in the digital economy, is a concept which has come to be recognised as Business Gamification. Thus, the purpose of this research paper is to further our understanding of game design elements for business, and investigate their properties from design to implementation in gamified systems. Following a two-year ethnographic style study with both a system development, and a communication agency largely staffed with GenY employees, findings suggest properties in game design elements are emergent and temporal in their instantiations.

Radial profile and log-normal fluctuations of intra-cluster medium as an origin of systematic bias of spectroscopic temperature

description: The origin of the recently reported systematic bias in the spectroscopic temperature of galaxy clusters is investigated using cosmological hydrodynamical simulations. We find that the local inhomogeneities of the gas temperature and density, after corrected for the global radial profiles, have nearly a universal distribution that resembles the log-normal function. Based on this log-normal approximation for the fluctuations in the intra-cluster medium, we develop an analytical model that explains the bias in the spectroscopic temperature discovered recently. We conclude that the multi-phase nature of the intra-cluster medium not only from the radial profiles but also from the local inhomogeneities plays an essential role in producing the systematic bias.

DFT investigation of 3d transition metal NMR shielding tensors in diamagnetic systems using the gauge-including projector augmented-wave method

description: We present a density functional theory based method for calculating NMR shielding tensors for 3d transition metal nuclei using periodic boundary conditions. Calculations employ the gauge-including projector augmented-wave pseudopotentials method. The effects of ultrasoft pseudopotential and induced approximations on the second-order magnetic response are intensively examined. The reliability and the strength of the approach for 49Ti and 51V nuclei is shown by comparison with traditional quantum chemical methods, using benchmarks of finite organometallic systems. Application to infinite systems is validated through comparison to experimental data for the 51V nucleus in various vanadium oxide based compounds. The successful agreement obtained for isotropic chemical shifts contrasts with full estimation of the shielding tensor eigenvalues, revealing the limitation of pure exchange-correlation functionals compared to their exact-exchange corrected analogues.

description: We present a search for electroweak production of single top quarks in the s-channel (p-pbar -> t bbar + X) and t-channel (p-pbar -> tq bbar + X) modes. We have analyzed 230 pb^(-1) of data collected with the D0 detector at the Fermilab Tevatron collider at a center-of-mass energy of sqrt(s) = 1.96 TeV. Two separate analysis methods are used: neural networks and a cut-based analysis. No evidence for a single top quark signal is found. We set 95% confidence level upper limits on the production cross sections using Bayesian statistics, based on event counts and binned likelihoods formed from the neural network output. The limits from the neural network (cut-based) analysis are 6.4 pb (10.6 pb) in the s-channel and 5.0 pb (11.3 pb) in the t-channel.
