description: Using MUSE AO data, we probe the ISM in the local spiral galaxy NGC 7793 at a spatial resolution of $\sim$ 10 pc. We identify HII regions and compile a catalogue of supernova remnants (SNRs), planetary nebulae (PNe) and Wolf Rayet stars (WR). We compute electron densities and temperatures from the [SII]6716/6731 and [SIII]6312/9069 line ratios. We study the properties of the ionised gas through BPT diagrams combined with gas velocity dispersion. We spectroscopically confirm 2 previously detected WR stars and a SNR and report the discovery of 7 WR, 1 SNR, and 2 PNe. The diffuse ionized gas (DIG) fraction is between $\sim$ 27 and 42% depending on the method used to define the HII region boundaries. In agreement with previous studies, we find that the DIG exhibits enhanced [SII]/H$α$ and [NII]/H$α$ ratios and a median temperature that is $\sim$ 3000 K higher than in HII regions. We also observe an apparent inverse correlation between temperature and H$α$ surface brightness. Overall, the observed [SII]6716/6731 ratio is consistent within 1$σ$ with $n_e$ < 30 cm$^{-3}$, with an almost identical distribution for the DIG and HII regions. The velocity dispersion of the ionised gas indicates that the DIG has a higher degree of turbulence than the HII regions. Comparison with photoionisation and shock models reveals that the diffuse component can only partially be explained via shocks and that it is most likely consistent with photons leaking from density bounded HII regions or with radiation from evolved field stars.

Η αξιολόγηση της ηλιοβοηθούμενης Α.Θ διεξάγεται για την Ελλάδα και συγκεκριμένα για τις δυο μεγαλύτερες πόλεις, την Αθήνα και την Θεσσαλονίκη. Για την επίτευξη των στόχων της εργασία, η ηλιοβοηθούμενη Α.Θ καθώς και το κτήριο μοντελοποιήθηκαν μαθηματικά στο TRNSYS και παραμετρικές αναλύσεις σε ετήσια βάση διεξήχθησαν. Οι παραμετρικές αναλύσεις είχαν ως στόχο να εξάγουν συμπεράσματα σχετικά με το μέγεθος της συστοιχίας των PVTs και της δεξαμενής αποθήκευσης της ηλιακής ενέργειας. Όλες οι εξομοιώσεις εκτελέστηκαν με ωριαίο βήμα καθώς και με την χρήση των διαθέσιμων μετεωρολογικών δεδομένα από το Meteonorm. Για την αξιολόγηση των αποτελεσμάτων έγινε χρήση πέντε ενεργειακών δεικτών με σημαντικότερο από αυτούς να είναι το ποσοστό κάλυψης της ηλεκτρικής ενέργειας από τα PVTs, Renewable Power Fraction. Τα αποτελέσματα δείχνουν ότι οι συνδυασμοί που περιέχουν τα λιγότερα PVT και την μεγαλύτερη σε όγκο ηλιακή δεξαμενή αποδίδουν βέλτιστα όσον αφορά την ειδική παραγωγικότητα τους, ενώ οι συνδυασμοί με τα περισσότερα PVT αποδίδουν βέλτιστα στον δείκτη SPF. Πιο συγκεκριμένα οι 4 συλλέκτες με τις δεξαμενές του 1.5 m3 απέδωσαν μέγιστη ειδική θερμική παραγωγικότητα, των 195.53 kWh∙m-2, και μέγιστη ειδική ηλεκτρική παραγωγικότητα, των 280.56 kWh∙m-2. Παράλληλα οι συνδυασμοί που περιείχαν 24 συλλέκτες παρουσίασαν μέγιστο COP στο 4.97, μέγιστο SPF στο 2.63 και μέγιστο RPF στο 12.86, δείχνοντας ότι το σύστημα είναι αυτοσυντηρούμενο και ότι μπορεί να καλύψει ακόμα και τις ηλεκτρικές ανάγκες της οικίας.

description: This paper studies of the multifractal dynamics in 84 cryptocurrencies. It fills an important gap in the literature, by studying this market using two alternative multi-scaling methodologies. We find compelling evidence that cryptocurrencies have different degree of long range dependence, and --more importantly -- follow different stochastic processes. Some of them follow models closer to monofractal fractional Gaussian noises, while others exhibit complex multifractal dynamics. Regarding the source of multifractality, our results are mixed. Time series shuffling produces a reduction in the level of multifractality, but not enough to offset it. We find an association of kurtosis with multifractality.
The effect of environmental changes on the photosynthesis and transpiration of rates of evergreen and deciduous trees during the summer, autumn, and winter periods
Creators: name: Kaile, Manmeet

description: By analyzing the seasonal changes in the photosynthesis (CO₂ uptake and fixation) and transpiration (water loss) rates of evergreen and deciduous trees, we can determine which trees should be promoted for future plantation projects, to develop a greener and more sustainable future. Trees exhibiting higher photosynthesis rates under various environmental conditions and growing seasons could reduce the rapidly increasing concentration of CO₂ in our atmosphere, and global warming. Evergreen and deciduous trees differ in their leaf senescence patterns through seasonal variations. Photosynthesis and transpiration rates were measured using the LI-COR LI-6200 Portable Photosynthesis System. Samples of evergreen and deciduous leaves under study were taken from 4 different tree species; 2 Evergreen Species: Thuja plicata (Western Red Cedar), Chamaecyparis lawsoniana (Lawson Cypress), and 2 Deciduous Species: Acer rubrum (Red Maple), Quercus rubra (Red Oak) on UBC's Sustainability Street, for a span of 9 months including summer, autumn, and winter (July 2010 - February 2011). Environmental factors such as light intensity, temperature, and the amount of precipitation were also recorded with observational data provided from Environment Canada's Historical Weather Database. Results showed higher photosynthetic and transpiration rates amongst the evergreen species during the fall/winter period, when compared to the deciduous species, as deciduous leaves undergo a senescence process due to environmental changes. Furthermore, specific protein gel analysis data through SDS-PAGE profiling and Western Blotting also showed higher levels of key photosynthesis proteins, light harvesting complex of photosystem II (LHCIIB), and the ribulose-1,5 bisphosphate carboxylase/oxygenase (RUBISCO) in evergreen species when compared to deciduous ones during the fall/winter. Photosynthesis and transpiration data will be discussed in relation to environmental parameters such as light intensity, temperature, and the amount of precipitation. The findings of this study will contribute to our knowledge about the role of these trees in CO₂ absorption and sustainable development.

description: We investigate the low-lying excitations of a stack of weakly-coupled two-dimensional Bose-Einstein condensates that is formed by a one-dimensional optical lattice. In particular, we calculate the dispersion relations of the monopole and quadrupole modes, both for the ground state as well as for the case in which the system contains a vortex along the direction of the lasers creating the optical lattice. Our variational approach enables us to determine analytically the dispersion relations for an arbitrary number of atoms in every two-dimensional condensate and for an arbitrary momentum. We also discuss the feasibility of experimentally observing our results.

Emergent conservation laws and nonthermal states in the mixed-field Ising model

description: This paper presents a method of computing approximate conservation laws and eigenstates of integrability-broken models using the concept of adiabatic continuation. Given some Hamiltonian, eigenstates and conserved operators may be computed by using those of a simple Hamiltonian close by in parameter space, dressed by some unitary rotation. However, most adiabatic continuation analyses only use this unitary implicitly. In this work, approximate adiabatic gauge potentials are used to construct a state dressing using variational methods, to compute eigenstates via a rotated truncated spectrum approximation. These methods allow construction of both low and high-energy approximate nonthermal eigenstates, as well as quasi-local almost-conserved operators, in models where integrability may be non-perturbatively broken. These concepts will be demonstrated in the mixed-field Ising model.

description: The LMA solution of the solar neutrino problem has been explored with the 1,000 ton liquid scinatillator detector, KamLAND. It utilizes nuclear power reactors distributing effectively 180km from the experimental site. Comparing observed neutrino rate with the calculation of reactor operation histories, an evidence for reactor neutrino disapearance has been obtained from 162 ton-year exposure data. This deficit is only compatible with the LMA solution and the other solutions in the two neutrino oscillation hypotheisis are excluded at 99.95% confidence level.

description: A morphism of a category which is simultaneously an epimorphism and a monomorphism is called a bimorphism. In \cite{DR2} we gave characterizations of monomorphisms (resp. epimorphisms) in arbitrary pro-categories, pro-(C), where (C) has direct sums (resp. weak push-outs). In this paper we introduce the notions of strong monomorphism and strong epimorphism. Part of their significance is that they are preserved by functors. These notions and their characterizations lead us to important classical properties and problems in shape and pro-homotopy. For instance, strong epimorphisms allow us to give a categorical point of view of uniform movability and to introduce a new kind of movability, the sequential movability. Strong monomorphisms are connected to a problem of K.Borsuk regarding a descending chain of retracts of ANRs. If (f: X \to Y) is a bimorphism in the pointed shape category of topological spaces, we prove that (f) is a weak isomorphism and (f) is an isomorphism provided (Y) is sequentially movable and $X$ or $Y$ is the suspension of a topological space. If (f: X \to Y) is a bimorphism in the pro-category pro-(H_0) (consisting of inverse systems in (H_0), the homotopy category of pointed connected CW complexes) we show that (f) is an isomorphism provided (Y) is sequentially movable.

description: Static oscillating bounces in Schwarzschild de Sitter spacetime are investigated. The oscillating bounce with many oscillations gives a super-thick bubble wall, for which the total vacuum energy increases while the mass of the black hole decreases due to the conservation of Arnowitt-Deser-Misner (ADM) mass. We show that the transition rate of such an "up-tunneling" consuming the seed black hole is higher than that of the Hawking-Moss transition. The correspondence of analyses in the static and global coordinates in the Euclidean de Sitter space is also investigated.

description: Conçu comme une introduction générale à la syntaxe, cet ouvrage présente les notions de base nécessaires à une étude de la combinaison des unités lexicales et grammaticales au sein d’un énoncé. Sans se placer dans un cadre préconçu, l’ouvrage étudie les différentes possibilités pour la représentation des structures syntaxiques, en fonction des principes généraux et des critères particuliers retenus. Élaboré avec l’objectif de fournir une base pour l’enseignement de la syntaxe à l’université, cet ouvrage souhaite montrer qu’on peut dégager de manière méthodique les propriétés des langues et mettre de l’ordre dans la forêt vierge que constitue chaque langue. Il est divisé en trois parties : comment élaborer le modèle d’une langue, comment déterminer les unités de base de la langue en fonction de leur sens, forme et combinatoire, comment définir et représenter les différents modes d’organisation des unités. Cette dernière partie présente une abondance de diagrammes syntaxiques de diverses natures. L’ouvrage est découpé en de petites sections, alternant le contenu principal avec des éclairages, des notes historiques, des élaborations plus formelles, des exemples linguistiques dans diverses langues, des propositions de lectures additionnelles et des exercices avec des éléments de correction.
Association between unconventional oil and gas (UOG) development and water quality in small streams overlying the Marcellus Shale
Creators: name: Knee, Karen

Publisher: name: American University
Year: 2023

description: Unconventional oil and gas (UOG) development has increased dramatically in the Marcellus Shale region over the past decade, and there is widespread public concern about the potential effects that UOG development may have on water quality. The goal of this study was to assess whether a suite of stream water quality constituents was related to the intensity of UOG development in corresponding catchments. Nineteen streams in southwestern Pennsylvania, where UOG development is prevalent, and 10 streams in western Maryland, where no UOG development has occurred, were sampled in summer 2013. Dissolved metals, radium isotopes, radon, specific conductance, stream discharge, and pH were measured. Principal component analysis revealed that samples tended to cluster by state, but some overlap in water quality existed between Maryland and Pennsylvania. Linear models were used to assess how response variables were related to UOG, other extractive activities, and landscape characteristics. These models showed that an index of oil and gas development had significant explanatory power for specific conductance, As, Ca, K, Mg, Na, and Sr. Other land use and land cover variables, such as forest, urban development, and coal mining, as well as stream discharge and pH, also were significantly associated with response variables. These results suggest that, in the Marcellus Shale region, UOG may elevate specific conductance and dissolved element concentrations in streams, but it should be considered in the context of broader patterns of land use and human activity.

description: This article investigates the long background to Mohandas K. Gandhi’s choice of salt as a symbol of protest against British colonial rule. Arguably the largest of all the colonial monopolies in India, the salt tax had the smallest effect on the lives of Indians when compared with other forms of deprivation and inequality. How was the salt monopoly different from other kinds of extractive colonialism? Why did salt never become part of the lexicon of protest against British rule until 1930? The article discusses the operation of the salt monopoly, its impact on consumption and health, the criticism it provoked, and the growth of support in the 1920s for protection for the domestic salt industry.

description: Non-equilibrium properties of quantum materials present many intriguing properties, among them athermal behavior, which violates the eigenstate thermalization hypothesis. Such behavior has primarily been observed in disordered systems. More recently, experimental and theoretical evidence for athermal eigenstates, known as "quantum scars" has emerged in non-integrable disorder-free models in one dimension with constrained dynamics. In this work, we show the existence of quantum scar eigenstates and investigate their dynamical properties in many simple two-body Hamiltonians with "staggered" interactions, involving ferromagnetic and antiferromagnetic motifs, in arbitrary dimensions. These magnetic models include simple modifications of widely studied ones (e.g., the XXZ model) on a variety of frustrated and unfrustrated lattices. We demonstrate our ideas by focusing on the two dimensional frustrated spin-1/2 kagome antiferromagnet, which was previously shown to harbor a special exactly solvable point with "three-coloring" ground states in its phase diagram. For appropriately chosen initial product states -- for example, those which correspond to any state of valid three-colors -- we show the presence of robust quantum revivals, which survive the addition of anisotropic terms. We also suggest avenues for future experiments which may see this effect in real materials.

description: The nonnegative Wigner function of all quantum states involved in teleportation of Gaussian states using the standard continuous-variable teleportation protocol means that there is a local realistic phase-space description of the process. This includes the coherent states teleported up to now in experiments. We extend the phase-space description to teleportation of non-Gaussian states using the standard protocol and conclude that teleportation of non-Gaussian states with fidelity of 2/3 is a "gold standard" for this kind of teleportation.

description: We discuss the gravitational wave background (GWB) from a cosmological population of gamma-ray bursts (GRBs). Among various emission mechanisms for the gravitational waves (GWs), we pay a particular attention to the vast anisotropic neutrino emissions from the accretion disk around the black hole formed after the so-called failed supernova explosions. The produced GWs by such mechanism are known as burst with memory, which could dominate over the low-frequency regime below \sim 10Hz. To estimate their amplitudes, we derive general analytic formulae for gravitational waveform from the axisymmetric jets. Based on the formulae, we first quantify the spectrum of GWs from a single GRB. Then, summing up its cosmological population, we find that the resultant value of the density parameter becomes roughly Ω_{GW} \approx 10^{-20} over the wide-band of the low-frequency region, f\sim 10^{-4}-10^1Hz. The amplitude of GWB is sufficiently smaller than the primordial GWBs originated from an inflationary epoch and far below the detection limit.

description: This article explores how Muslim women’s activism unfolds in the context of anti-Muslim racism and Islamism in contemporary Germany. In particular, it identifies both gendered forms of anti-Muslim racism and Islamism encountered by Muslim women’s organizations and ways they respond to it. Drawing on theories of intersectionality and boundary making, this study identifies the most common strategies used to confront anti-Muslim racism and Islamism and their implications for intersectional boundary making. For this purpose, six expert interviews with representatives of major Muslim women’s organizations were conducted and supplemented by data from internet research and participatory observation. Based on a Grounded Theory-inspired approach, the findings show that the responses of Muslim women’s organizations to anti-Muslim racism and Islamism reconfigure group boundaries. They create more inclusive spaces in which boundary formations by religion, race, and ethnicity and gender are transcended.

description: We propose an alternative implementation of the Projected Gross-Pitaevskki equation adapted for numerical modeling of the atomic Bose-Einstein condensate trapped in a toroidally-shaped potential. We present an accurate and efficient scheme to evaluate the required matrix elements and calculate time evolution of the matter wave field. We analyze the stability and accuracy of the developed method for equilibrium and nonequilibrium solutions in a ring-shaped trap with additional barrier potential corresponding to recent experimental realizations.

description: Τα συνελικτικά νευρωνικά δίκτυα (CNN) είναι η ραχοκοκαλιά της κατηγοριοποίησης εικόνων, ένα φαινόμενο βαθιάς μάθησης που παίρνει μια εικόνα και της αποδίδει μια κλάση και μια ετικέτα που την κάνει μοναδική. Η ταξινόμηση εικόνων με χρήση CNN αποτελεί σημαντικό μέρος των πειραμάτων μηχανικής μάθησης. Μαζί με τη χρήση των συνελικτικών νευρωνικών δικτύων και των επαγόμενων δυνατοτήτων του, χρησιμοποιείται πλέον ευρέως για μια σειρά εφαρμογών - από την προσθήκη ετικετών στο Facebook έως τις συστάσεις προϊόντων της Amazon και τις εικόνες υγειονομικής περίθαλψης έως τα αυτόματα αυτοκίνητα. Ο λόγος που τα ΣΝΔ είναι τόσο δημοφιλή είναι ότι απαιτούν πολύ λίγη προεπεξεργασία, που σημαίνει ότι μπορούν να διαβάσουν 2D εικόνες εφαρμόζοντας φίλτρα που άλλοι συμβατικοί αλγόρι- θμοι δεν μπορούν. Θα εμβαθύνουμε στη διαδικασία του πώς λειτουργεί η ταξινόμηση εικόνων χρησιμοποιώντας ΣΝΔ. Στην παρούσα διπλωματική εργασία, ερευνούμε τις εφαρμογές της μεταφοράς γνώσης στο πεδίο των νευρωνικών δικτύων. Πιο συγκεκριμένα, προσπαθήσαμε να εφαρμό- σουμε τεχνικές μεταφοράς γνώσης σε εργασίες κατηγοριοποίησης εικόνας και συστή- ματα συστάσεων. Για την υλοποίηση, συγκρίναμε προεκπαιδευμένα μοντέλα (VGG19, ResNet50, InceptionV3) με απλά συνελικτικά μοντέλα για να διαπιστώσουμε αν όντως η μεταφορά γνώσης πραγματικά βελτιώνει αισθητά την απόδοση των μοντέλων και το στόχο των εργασιών μας. Στο πεδίο της υπολογιστικής όρασης και πιο συγκεκριμένα της αναγνώρισης εικόνας βρίσκουμε αρκετά τέτοια αποτελέσματα όπου μπορούμε να καταλάβουμε ουσιαστικά τη βοήθεια που προσφέρει η μεταφορά γνώσης απο τα προεκ- παιδευμένα μοντέλα. Η είσοδος στον αλγόριθμό μας θα είναι μια εικόνα οποιουδήποτε αντικειμένου που ο πελάτης θέλει να αγοράσει. Οι δύο εργασίες που θέλουμε να επιτύχουμε είναι: • η κατηγοριοποίηση της φωτογραφίας ενός προϊόντος, σε σχέση με προϊόντα που είναι πιθανότερο να μοιάζουν • η σύσταση παρόμοιων προϊόντων με αυτό που έχουμε εισάγει Ο στόχος μας είναι αφού εκτελέσουμε τα δύο διαφορετικά πειράματα, να συγκρίνουμε τα προεκπαιδευμένα μοντέλα, δηλαδή αυτά τα μοντέλα που έχουν ήδη εκπαιδευτεί στο σύνολο δεδομένων ImageNet, με αυτά που είναι μη προεκπαιδευμένα όσον αφορά την ακρίβεια και την απώλεια και εν τέλει στο πόσες ”σωστές” προβλέψεις κάνουν και αν επιτυγχάνεται ο τελικός στόχος κάθε εργασίας.
The role of audit quality in form valuation : The case of R&D capitalization in Australia

description: This study investigates the link between audit quality and the market’s perception of the value of discretion in accounting for R&D costs (Australian GAAP permits R&D costs to be capitalized) and the impact of changes in that discretion. The study examines companies reporting capitalized R&D costs over the period 1992 to 1998. When management discretion is unencumbered (1992 to 1995), the use of a higher quality auditor appears to significantly enhance the value of the R&D asset. However, when management discretion is reduced, due to enhanced monitoring by the Australian Securities Commission (1996 to 1998), the use of a higher quality auditor does not increase the value relevance of the R&D asset. These results are consistent with the notion that in the absence of other monitoring mechanisms, audit quality signals the value relevance of the R&D asset. In addition, the R&D expensed by these “capitalizers” is not significant in the earlier sub-period but is significant in the later sub-period when management discretion is reduced.

description: The effective mass approximation (EMA) could be an efficient method for the computational study of semiconductor nanostructures with sizes too large to be handled by first-principles calculations, but the scheme to accurately and reliably introduce EMA parameters for given nanostructures remains to be devised. Herein, we report on an EMA approach based on first-principles-derived data, which enables accurate predictions of the optoelectronic properties of quantum nanostructures. For the CdS/ZnS core/shell quantum rods, for which we recently reported its experimental synthesis, we first carry out density functional theory (DFT) calculations for an infinite nanowire to obtain the nanoscopic dielectric constant, effective mass, and Kohn-Sham potential. The DFT-derived data are then transferred to the finite nanorod cases to set up the EMA equations, from which we estimate the photoluminescence (PL) characteristics. Compared with the corresponding method based on bulk EMA parameters and abrupt potential, we confirm that our EMA approach more accurately describes the PL properties of nanorods. We find that, in agreement with the experimentally observed trends, the optical gap of nanorods is roughly determined by the nanorod diameter and the PL intensity is reduced with increasing the nanorod length. The developed methodology is additionally applied to CdSe nanoplatelets, where reliable experimental data became recently available. Here, we again obtain excellent agreements between calculated and measured optical gap values, confirming the generality of our approach. It is finally shown that the abrupt confinement potential approximation most adversely affects the accuracy of EMA simulations.

What client and auditor attributes are associated with auditors' decision to require adjustments to pre-audit financial statements?

description: An important outcome of the audit process is the adjustments to the pre-audit financial statements prepared by managers. We provide empirical evidence on the determinants of auditors’ decision to require adjustments to the pre-audit financial statements. We find that clients with higher pre-adjusted discretionary accruals are more likely to receive downward adjustments to pretax income and clients with lower effective tax rates are more likely to receive upward adjustments to taxes payable. However, auditors are less likely to require downward income adjustments when their clients’ pre-adjusted return on equity is just above the critical cutoff that qualifies them for stock listing or new share offering. Our results support the notion that auditors correct for management bias, but not to the extent to cause severe adverse consequences to their clients. Adjustments of both income and tax obligation are also influenced by several attributes of signatory auditors including industry specialization, independence from the client, the rank, and gender of the auditor.
A Radio Outburst Nearly Coincident with the Large X-ray Flare from Sgr A* on 2002-10-03

description: A large radio outburst from Sgr A* was observed during the VLA weekly monitoring program at 2 cm, 1.3 cm and 7 mm, nearly coincident with the brightest X-ray flare detected to date with the XMM-Newton X-ray Observatory on 2002-10-03. The flux density of 1.9$\pm$0.2 Jy measured at 7 mm exceeds the mean value (1.00$\pm$0.01 Jy) by a factor of $\sim 2$, one of the two highest increases observed during the past three years (June 2000-October 2003), while less significant increases in flux densities were observed at 1.3 cm and 2 cm. The radio observation started 13.5 hrs after the onset of the X-ray flare (which had occurred over a 45 min duration) and continued for 1.3 hrs. During the observation, there was no significant ($<3σ$) change in the radio flux densities at all the three wavelengths, indicating that the radio outburst varied on a timescale of $>1$hr. A spectral index of $α=2.4^{+0.3}_{-0.6}$ (${\rm S \proptoν^α}$) was derived for the outburst component, consistent with an optically thick nonthermal synchrotron source. These results suggest that energetic electrons responsible for the radio outburst might be produced via a process associated with the X-ray flare, then transported to large radii, producing the observed radio outburst. The observation is the first evidence for a correlated variation in the radio and X-ray emissions from Sgr A*.
