description: Spinfoam theories are hoped to provide the dynamics of non-perturbative loop quantum gravity. But a number of their features remain elusive. The best studied one -the euclidean Barrett-Crane model- does not have the boundary state space needed for this, and there are recent indications that, consequently, it may fail to yield the correct low-energy $n$-point functions. These difficulties can be traced to the SO(4) -> SU(2) gauge fixing and the way certain second class constraints are imposed, arguably incorrectly, strongly. We present an alternative model, that can be derived as a bona fide quantization of a Regge discretization of euclidean general relativity, and where the constraints are imposed weakly. Its state space is a natural subspace of the SO(4) spin-network space and matches the SO(3) hamiltonian spin network space. The model provides a long sought SO(4)-covariant vertex amplitude for loop quantum gravity.

description: Η διαχείριση πόρων έχει αναγνωριστεί ως σημαντικό θέμα για την εκτέλεση επιχειρησιακών διαδικασιών εδώ και πολύ καιρό. Ο σχεδιασμός και η διαχείριση των επιχειρησιακών διαδικασιών έχουν αυξηθεί σημαντικά την τελευταία δεκαετία. Η ικανότητα διαχείρισης των επιχειρησιακών διαδικασιών όσο το δυνατόν πιο αποτελεσματικά και ευέλικτα έχει γίνει ένας από τους πιο κρίσιμους παράγοντες επιτυχίας για τις σημερινές εταιρείες. Στην πραγματικότητα, πρόσφατα ανακαλύφθηκε ότι η ικανοποίηση των πελατών προκύπτει κυρίως από την εξυπηρέτηση, και έτσι οι περισσότερες εταιρείες προσπαθούν να βελτιώσουν το σχεδιασμό, την ανάπτυξη και την παροχή υπηρεσιών προκειμένου να ανταποκριθούν στις απαιτήσεις των πελατών. Ο εντοπισμός και η κατανομή των σωστών πόρων στη σωστή διαδικασία οδηγεί σε διασφάλιση ποιότητας και αποτελεσματική απόδοση. Τα επιχειρηματικά μοντέλα συνήθως υποφέρουν από σπατάλη ή κακή κατανομή πόρων. Στην παρούσα διπλωματική, εξετάζεται σε βάθος το θέμα της ανάθεσης πόρων σε επιχειρηματικές διαδικασίες μέσα από τη βιβλιογραφία, δίνοντας έμφαση σε συγκεκριμένες ρεαλιστικές περιπτώσεις.
description: Resource management has long been recognized as an important issue in the execution of business processes. Business process design and management have grown in importance over the past decade. The ability to manage business processes as efficiently and flexibly as possible has become one of the most critical success factors for today's companies. In fact, it has recently been discovered that customer satisfaction is mainly derived from service, so most companies are trying to improve design, development and service delivery in order to meet customer demands. Identifying and allocating the right resources to the right process leads to quality assurance and efficient performance. Business models usually suffer from wasted or misallocated resources. In this thesis, the literature on resource allocation in business processes is investigated in depth focusing on specific realistic cases.

description: Reliable and precise measurements of the relative energy of band edges in semiconductors are needed to determine band gaps and band offsets, as well as to establish the band diagram of devices and heterostructures. These measurements are particularly important in the field of two-dimensional materials, in which many new semiconducting systems are becoming available through exfoliation of bulk crystals. For two-dimensional semiconductors, however, commonly employed techniques suffer from difficulties rooted either in the physics of these systems, or of technical nature. The very large exciton binding energy, for instance, prevents the band gap to be determined from a simple spectral analysis of photoluminescence, and the limited lateral size of atomically thin crystals makes the use of conventional scanning tunneling spectroscopy cumbersome. Ionic gate spectroscopy is a newly developed technique that exploits ionic gate field-effect transistors to determine quantitatively the relative alignment of band edges of two-dimensional semiconductors in a straightforward way, directly from transport measurements (i.e., from the transistor electrical characteristics). The technique relies on the extremely large geometrical capacitance of ionic gated devices that -- under suitable conditions -- enables a change in gate voltage to be directly related to a shift in chemical potential. Here we present an overview of ionic gate spectroscopy, and illustrate its relevance with applications to different two-dimensional semiconducting transition metal dichalcogenides and van der Waals heterostructures.

description: Context: Be stars are massive dwarf or subgiant stars that present temporary emission lines in their spectrum, and particularly in the Halpha line. The mechanism triggering these Be episodes is currently unknown, but binarity could play an important role. Aims: Previous observations with the VLT/VISIR instrument (Kervella & Domiciano de Souza 2007) revealed a faint companion to Achernar, the brightest Be star in the sky. The present observations are intended to characterize the physical nature of this object. Methods: We obtained near-IR images and an H-band spectrum of Achernar B using the VLT/NACO adaptive optics systems. Results: Our images clearly show the displacement of Achernar B over a portion of its orbit around Achernar A. Although these data are insuficient to derive the orbital parameters, they indicate a period of the order of 15 yr. The projected angular separation of the two objects in December 2007 was smaller than 0.15 arcsec, or 6.7 AU at the distance of Achernar. Conclusions: From its flux distribution in the near- and thermal-IR, Achernar B is most likely an A1V-A3V star. Its orbital period appears similar to the observed pseudo-periodicity of the Be phenomenon of Achernar. This indicates that an interaction between A and B at periastron could be the trigger of the Be episodes.

description: This paper explores the mapping between the observable properties of a stellar halo in phase- and abundance-space and the parent galaxy's accretion history in terms of the characteristic epoch of accretion and mass and orbits of progenitor objects. The study utilizes a suite of eleven stellar halo models constructed within the context of a standard LCDM cosmology. The results demonstrate that coordinate-space studies are sensitive to the recent (0-8 Gyears ago) merger histories of galaxies (this timescale corresponds to the last few to tens of percent of mass accretion for a Milky-Way-type galaxy). Specifically, the {\it frequency, sky coverage} and {\it fraction of stars} in substructures in the stellar halo as a function of surface brightness are indicators of the importance of recent merging and of the luminosity function of infalling dwarfs. The {\it morphology} of features serves as a guide to the orbital distribution of those dwarfs. Constraints on the earlier merger history (> 8 Gyears ago) can be gleaned from the abundance patterns in halo stars: within our models, dramatic differences in the dominant epoch of accretion or luminosity function of progenitor objects leave clear signatures in the [alpha/Fe] and [Fe/H] distributions of the stellar halo - halos dominated by very early accretion have higher average [alpha/Fe], while those dominated by high luminosity satellites have higher [Fe/H]. This intuition can be applied to reconstruct much about the merger histories of nearby galaxies from current and future data sets.

description: We report on diffraction measurements on multiferroic TbMnO3 which demonstrate that the Tb- and Mn-magnetic orders are coupled below the ferroelectric transition TFE = 28 K. For T < TFE the magnetic propagation vectors (tau) for Tb and Mn are locked so that tauTb = tauMn, while below TNTb = 7 K we find that tauTb and tauMn lock-in to rational values of 3/7 b* and 2/7 b*, respectively, and obey the relation 3tauTb - tauMn = 1. We explain this novel matching of wave vectors within the frustrated ANNNI model coupled to a periodic external field produced by the Mn-spin order. The tauTb = tauMn behavior is recovered when Tb magnetization is small, while the tauTb = 3/7 regime is stabilized at low temperatures by a peculiar arrangement of domain walls in the ordered state of Ising-like Tb spins.

description: AU Pegasi is a pulsating star in a spectroscopic binary system with an orbital period of 53.26 days. Between 1960 and 1990 an extremely rapid period increase was observed in the value of the pulsation period, but in the last 15 years the observation show that the period set in 2.411 days. Fourier analysis of photometric data obtained during the ASAS project and those taken at the Piszkesteto Mountain Station of the Konkoly Observatory during 1994-2005 indicate that AU Pegasi is pulsating in two modes simultaneously, and the ratio of the frequencies of the two modes is 0.706, a value common for double-mode classical Cepheids. A careful analysis of other photometric observations obtained during the era of the strong period increase also revealed existence of a second mode. This may suggest that this star is not a Type II Cepheid, despite its galactic position.

description: The magnetic switchbacks observed recently by the Parker Solar Probe have raised the question about their nature and origin. One of the competing theories of their origin is the interchange reconnection in the solar corona. In this scenario, switchbacks are generated at the reconnection site between open and closed magnetic fields, and are either advected by an upflow or propagate as waves into the solar wind. In this paper we test the wave hypothesis, numerically modelling the propagation of a switchback, modelled as an embedded Alfvén wave packet of constant magnetic field magnitude, through the gravitationally stratified solar corona with different degrees of background magnetic field expansion. While switchbacks propagating in a uniform medium with no gravity are relatively stable, as reported previously, we find that gravitational stratification together with the expansion of the magnetic field act in multiple ways to deform the switchbacks. These include WKB effects, which depend on the degree of magnetic field expansion, and also finite-amplitude effects, such as the symmetry breaking between nonlinear advection and the Lorentz force. In a straight or radially expanding magnetic field the propagating switchbacks unfold into waves that cause minimal magnetic field deflections, while a super-radially expanding magnetic field aids in maintaining strong deflections. Other important effects are the mass uplift the propagating switchbacks induce and the reconnection and drainage of plasmoids contained within the switchbacks. In the Appendix, we examine a series of setups with different switchback configurations and parameters, which broaden the scope of our study.

description: We study a system of a complex charged scalar coupled to a Reissner-Nordstrom black hole in 3+1 dimensional anti-de Sitter spacetime, neglecting back-reaction. With suitable boundary conditions, the cases of a neutral and purely electric black hole have been studied in various limits and were shown to yield key elements of superconductivity in the dual 2+1 dimensional field theory, forming a condensate below a critical temperature. By adding magnetic charge to the black hole, we immerse the superconductor into an external magnetic field. We show that a family of condensates can form and we examine their structure. For finite magnetic field, they are localized in one dimension with a profile that is exactly solvable, since it maps to the quantum harmonic oscillator. As the magnetic field increases, the condensate shrinks in size, which is reminiscent of the Meissner effect.

description: We consider the minimal two-band model for the Fe-based superconductors with a phenomenological pairing interaction which mimics short-range antiferromagnetic (AFM) fluctuations. Two superconducting (SC) gap solutions are found to exist with the model: sign-changing s-wave gap ($\pm$s-wave) and double d-wave gap states. Both solutions hold the approximate relation $Δ_{h} ^{max} N_h \approx Δ_{e} ^{max} N_e$, a generic feature of two band model with a dominant interband pairing interaction. We carried out the calculations of the SC properties of the both SC states such as the density of states, temperature dependencies of spin-lattice relaxation rate $1/T_1$, Knight shift, and penetration depth, particularly taking into account of the interband coherence factors. The results are discussed in comparison with the currently available experimental data.

description: A notion of local $U$-statistic process is introduced and central limit theorems in various norms are obtained for it. This involves the development of several inequalities for $U$-processes that may be useful in other contexts. This local $U$-statistic process is based on an estimator of the density of a function of several sample variables proposed by Frees [J. Amer. Statist. Assoc. 89 (1994) 517--525] and, as a consequence, uniform in bandwidth central limit theorems in the sup and in the $L_p$ norms are obtained for these estimators.

description: This paper delves into the celebration of Saint Gregory Palamas from a musicology perspective, with a focus on the two verses that exist today in the Triodion on the day of his feast, in the Vespers and the Aeneid. The paper is structured as follows: the first part consists of the biography of St. Gregory Palamas, the tradition of moving his feast day celebration and finally, how he is depicted in iconography. This part also includes a presentation of the two verses in poetic form along with a brief analyses of their content. The second part outlines the historical context of the time, and the distinguishing features of the works of two composers, Peter Peloponnesius and James Precentor, whose compositions are studied. Furthermore, it also highlights the melopoeia genres and key characteristics of plagal second mode, offering crucial context for the ensuing analysis. The third part represents the musicological analysis, i.e. the melodies with their transcriptions from the Old Method and their transcriptions according to the New Method.The paper concludes with tables and findings regarding the composition process.

description: We present results from seven cosmological simulations that have been extended beyond the present era as far as redshift $z=-0.995$ or $t\approx96\,{\rm Gyr}$, using the Enzo simulation code. We adopt the calibrated star formation and feedback prescriptions from our previous work on reproducing the Milky Way with Enzo with modifications to the simulation code, chemistry and cooling library. We then consider the future behaviour of the halo mass function (HMF), the equation of state (EOS) of the IGM, and the cosmic star formation history (SFH). Consistent with previous work, we find a freeze-out in the HMF at $z\approx-0.6$. The evolution of the EOS of the IGM presents an interesting case study of the cosmological coincidence problem, where there is a sharp decline in the IGM temperature immediately after $z=0$. For the SFH, the simulations produce a peak and a subsequent decline into the future. However, we do find a turnaround in the SFH after $z\approx-0.98$ in some simulations, probably due to the limitations of the criteria used for star formation. By integrating the SFH in time up to $z=-0.92$, the simulation with the best spatial resolution predicts an asymptotic total stellar mass that is very close to that obtained from extrapolating the fit of the observed SFR. Lastly, we investigate the future evolution of the partition of baryons within a Milky Way-sized galaxy, using both a zoom and a box simulation. Despite vastly different resolutions, these simulations predict individual haloes containing an equal fraction of baryons in stars and gas at the time of freeze-out ($t\approx30\,{\rm Gyr}$).

description: Model-based Systems Engineering (MBSE) provides features for behavioral analysis, requirements traceability, system architecture, simulation, testing, and performance analysis that are imperative for the testing of safety-critical systems. In this report, we present a case study of a simple safety-critical system, and model the system using UML (Unified Modeling Language), SysML (Systems Modeling Language), and AADL (Architecture Analysis and Design Language). We then extend the AADL model with user-defined properties and annexes to augment additional analysis and reporting capabilities relevant to safety-critical systems. As safety and security expectations grow in concert with system complexity, MBSE will become increasingly ingrained in the workflow of the systems and software engineering communities.

description: Ozone has the potential to cause many health problems. Most of the human population exposure to ozone occurs indoors. It has been previously reported that the average ozone penetration factor into the occupied space is 0.79. However, this value does not account for the pathway by which ozone enters the occupied space. A model to determine the amount that unoccupied spaces contribute to the ozone concentration in the occupied space is presented in this thesis. A literature review was then performed to identify parameters for the model as well as gaps that exist in the literature pertaining to the model developed. One of the biggest gaps was the lack of ozone decay rates in unoccupied spaces, such as garages, attics and crawl spaces. Because of this, a field study was designed and completed to determine the ozone decay rate in garages. It was determined that the average ozone decay rate in garages is 2.7 (± 1.1) hr-1. This value is comparable to previous data for occupied space ozone decay rates. Using these data as well as other published data, it was determined that, under normal conditions, ozone penetration through unoccupied spaces to the occupied space is not a significant pathway. However, there are some conditions for which unoccupied spaces may be a major pathway for ozone entry into homes. One example of this is when both the garage door and the door connecting to garage to the occupied space is opened for a long time. Under these conditions, the occupied space can reach an indoor/outdoor (IO) concentration of 0.46. As can be seen, under this condition, unoccupied spaces do provide substantial contribution of ozone to the occupied space

description: In a broadcast channel with random packet arrival and transmission queues, the stability of the system is achieved by maximizing a weighted sum rate capacity with suitable weights that depend on the queue size. The weighted sum rate capacity using Dirty Paper Coding (DPC) and Zero Forcing (ZF) is asymptotically equivalent to the weighted sum capacity over parallel single-channels. In this paper, we study the Diversity Multiplexing Tradeoff (DMT) of the fading broadcast channel under a fixed weighted sum rate capacity constraint. The DMT of both identical and different parallel weighted MISO channels is first derived. Finally, we deduce the DMT of a broadcast channel using DPC and ZF precoders.

description: Massive scalar fields provide excellent dark matter candidates, whose dynamics are often explored analytically and numerically using nonrelativistic Schrödinger-Poisson (SP) equations in a cosmological context. In this paper, starting from the nonlinear and fully relativistic Klein-Gordon-Einstein (KGE) equations in an expanding universe, we provide a systematic framework for deriving the SP equations, as well as relativistic corrections to them, by integrating out `fast modes' and including nonlinear metric and matter contributions. We provide explicit equations for the leading-order relativistic corrections, which provide insight into deviations from the SP equations as the system approaches the relativistic regime. Upon including the leading-order corrections, our equations are applicable beyond the domain of validity of the SP system, and are simpler to use than the full KGE case in some contexts. As a concrete application, we calculate the mass-radius relationship of solitons in scalar dark matter and accurately capture the deviations of this relationship from the SP system towards the KGE one.

description: Most asteroids are somewhat elongated and have non-zero lightcurve amplitudes. Such asteroids can be detected in large-scale sky surveys even if their mean magnitudes are fainter than the stated sensitivity limits. We explore the detection of elongated asteroids under a set of idealized but useful approximations. We find that objects up to 1 magnitude fainter than a survey's sensitivity limit are likely to be detected, and that the effect is most pronounced for asteroids with lightcurve amplitudes 0.1-0.4 mag.This imposes a bias on the derived size and shape distributions of the population that must be properly accounted for.

description: Link prediction and node classification are two important downstream tasks of network representation learning. Existing methods have achieved acceptable results but they perform these two tasks separately, which requires a lot of duplication of work and ignores the correlations between tasks. Besides, conventional models suffer from the identical treatment of information of multiple views, thus they fail to learn robust representation for downstream tasks. To this end, we tackle link prediction and node classification problems simultaneously via multi-task multi-view learning in this paper. We first explain the feasibility and advantages of multi-task multi-view learning for these two tasks. Then we propose a novel model named as MT-MVGCN to perform link prediction and node classification tasks simultaneously. More specifically, we design a multi-view graph convolutional network to extract abundant information of multiple views in a network, which is shared by different tasks. We further apply two attention mechanisms: view attention mechanism and task attention mechanism to make views and tasks adjust the view fusion process. Moreover, view reconstruction can be introduced as an auxiliary task to boost the performance of the proposed model. Experiments on real-world network datasets demonstrate that our model is efficient yet effective, and outperforms advanced baselines in these two tasks.

description: Summary: This study aims to investigate the impact of a 40‐min nap opportunity on perceived recovery, exertion, and maximal voluntary isometric contraction (MVIC) following the 5‐m shuttle run test (5SRT), after 1 night of normal sleep. In a randomised, counterbalanced, cross‐over design, 17 trained men (mean [SD] age 20 [3] years, height 173 [6] cm, body mass 68 [6] kg) performed a 5SRT under two conditions: a 40‐min nap opportunity and no‐nap condition. After both conditions, electromyography signals during a 5‐s isometric knee extension were recorded before and immediately after the 5SRT. Two electrical nerve stimulations at the femoral nerve were measured during and after the MVIC. Force, voluntary activation level, M‐wave amplitudes, potentiated twitch, and electromyography signals (root mean square) were measured during each MVIC. Perceived exertion was recorded after each repetition of the test and perceived recovery was determined after the end of the MVIC. Compared to the no‐nap condition, the 40‐min nap resulted in significant enhancements in both the highest distance (p < 0.01, Δ = +7.6%) and total distance (p < 0.01, Δ = +7.5%). Before and after exercise, values for MVIC, root mean square, M‐wave amplitudes, and voluntary activation level were improved after the 40‐min nap opportunity compared to no‐nap condition (all p ≤ 0.01). Values for perceived exertion and recovery were improved after the 40‐min nap opportunity in comparison with no‐nap condition (p ≤ 0.01). A 40‐min nap opportunity improved repeated high‐intensity short‐term maximal performance, perceived recovery, associated neuromuscular responses, and reduced perceived fatigue. Therefore, our findings suggest that central and peripheral processes are involved in the improvements of 5SRT performance after napping.

description: Additional file 4: Figure S3. Validation of sexual dimorphic transcriptional differences in podocyte. Transcriptomic data were confirmed with qRT-PCR including podocyte specific-genes from isolated podocytes of additional mice. Criteria for gene selection were intrinsically sexually dimorphic podocyte-specific genes with biological relevance for kidney physiology and disease such as Slc6a6, Arhgap32 and Tjp1 as well as genes representing main sexual dimorphic GOs such as for “ribosomal proteins” Rpl13 and “mitochondria/oxidative phosphorylation” Cox7a2. Further genes Daam2, Ctsl and Arhgap32 were chosen for their relation to kidney diseases and the fact that they did not only show intrinsic sexual dimorphism but were additionally significantly differently regulated in male after rapamycin treatment. Other criteria for gene selection were transcript level expressions higher than 1000, log2FC differences between at least two experimental groups of 0.5–2.0. a qPCR results presented as mRNA expression changes from male and female vehicle podocytes (n = 4–8) in the left panel (P-values are indicated below each gene name), right panel shows expression level changes of RNA-seq for respective genes of vehicle groups, all genes were normalized to male vehicle, b qPCR results presented as mRNA expression changes from male rapamycin and male vehicle podocytes (n = 4–8) in the left panel (P-values are indicated below each gene name), right panel shows expression level changes of RNA-seq for respective genes of male rapamycin and vehicle groups, all genes were normalized to male vehicle (c) qPCR results presented as mRNA expression changes from female rapamycin and female vehicle podocytes (n = 5–9) in the left panel (P-values are indicated below each gene name), right panel shows expression level changes of RNA-seq for respective genes of female rapamycin and vehicle groups, all genes were normalized to female vehicle, Reference genes used for normalization were Hdgf and Ywhaz genes.

description: The distribution of luminous radio galaxies in galaxy clusters has been observed to be concentrated in the inner region. We consider the role of dynamical friction of massive galaxies ($M\sim 10^{12.5}$ M$_{\odot}$), assuming them to be hosts of luminous radio galaxies, and show that beginning with a Navarro-Frenk-White density profile of a cluster of mass $M_{cl}\sim 10^{15}$ M$_{\odot}$ of concentration $c\sim 5$ and collapsing at $z\sim 1$, the density profile of radio galaxies evolve to a profile of concentration $c \sim 25$, as observed, in a time scale of $t\sim 3\hbox{--}5$ Gyr.

An experimental investigation of the behaviour of connections in thin precast concrete panels under earthquake loading
Creators: name: Kallros, Mikael Kaj
Publisher: name: University of British Columbia
Year: 2010

description: Investigations of connections for precast concrete panel buildings have shown that it is difficult to design an embedded connection that will perform well under earthquake loading. Some typical connections use studs or reinforcing bars embedded in the edge of the panel. These are then welded or bolted to an adjacent panel. During earthquake loading the crushing of concrete around the embedment usually leads to premature loss of strength and stiffness of the connection before significant ductility can develop. It has been found that connection performance improves with increasing panel thickness. The behaviour of embedded connections in thin precast concrete panels was investigated. The intent was to improve connection design details and to develop a simple method of predicting connection strengths with panel thicknesses of 50 mm to 75 mm. Sixteen connections of six different types were tested. Three were tested monotonically and thirteen were tested under reversed cyclic loading. Certain types of connections can be used to transfer earthquake loads between thin concrete panels as long as they have adequate strength. Methods for predicting the strength of connections are discussed. The connections tested should not be relied on to develop ductility.
