description: We have examined the relationship between supermassive black hole mass (M$_{BH}$) and the stellar mass of the host spheroid (M$_{sph,*}$) for a sample of 75 nearby galaxies. To derive the spheroid stellar masses we used improved 2MASS K$_s$-band photometry from the ARCHANGEL photometry pipeline. Dividing our sample into core-Sérsic and Sérsic galaxies, we find that they are described by very different M$_{BH}$-M$_{sph,*}$ relations. For core-Sérsic galaxies - which are typically massive and luminous, with M$_{BH} \gtrsim 2x10^8 M_\odot$ - we find M$_{BH} \propto M_{sph,*}^{(0.97 \pm 0.14)}$, consistent with other literature relations. However, for the Sérsic galaxies - with typically lower masses, M$_{sph,*} \lesssim 3x10^10 M_\odot$ - we find M$_BH \propto M_{sph,*}^{(2.22 \pm 0.58)}$, a dramatically steeper slope that differs by more than 2 standard deviations. This relation confirms that, for Sérsic galaxies, M$_{BH}$ is not a constant fraction of M$_{sph,*}$. Sérsic galaxies can grow via the accretion of gas which fuels both star formation and the central black hole, as well as through merging. Their black hole grows significantly more rapidly than their host spheroid, prior to growth by dry merging events that produce core-Sérsic galaxies, where the black hole and spheroid grow in lock step. We have additionally compared our Sérsic M$_{BH}$-M$_{sph,*}$ relation with the corresponding relation for nuclear star clusters, confirming that the two classes of central massive object follow significantly different scaling relations.

description: We describe the use of quantum process calculus to describe and analyze quantum communication protocols, following the successful field of formal methods from classical computer science. We have extended the quantum process calculus to describe d-dimensional quantum systems, which has not been done before. We summarise the necessary theory in the generalisation of quantum gates and Bell states and use the theory to apply the quantum process calculus CQP to quantum protocols, namely qudit teleportation and superdense coding.

description: We perform a state-of-the-art global fit to all Higgs data. We synthesise them into a 'universal' form, which allows to easily test any desired model. We apply the proposed methodology to extract from data the Higgs branching ratios, production cross sections, couplings and to analyse composite Higgs models, models with extra Higgs doublets, supersymmetry, extra particles in the loops, anomalous top couplings, invisible Higgs decay into Dark Matter. Best fit regions lie around the Standard Model predictions and are well approximated by our 'universal' fit. Latest data exclude the dilaton as an alternative to the Higgs, and disfavour fits with negative Yukawa couplings. We derive for the first time the SM Higgs boson mass from the measured rates, rather than from the peak positions, obtaining $M_h = 125.0 \pm 1.8$ GeV.

Magnetar giant flare oscillations and the nuclear symmetry energy

description: If the observed quasi-periodic oscillations in magnetar flares are partially confined to the crust, then the oscillation frequencies are unique probes of the nuclear physics of the neutron star crust. We study crustal oscillations in magnetars including corrections for a finite Alfven velocity. Our crust model uses a new nuclear mass formula that predicts nuclear masses with an accuracy very close to that of the finite range droplet model. This mass model for equilibrium nuclei also includes shell corrections and an updated neutron-drip line. We perturb our crust model to predict axial crust modes and assign them to observed giant flare quasi-periodic oscillation frequencies from the soft gamma-ray repeater SGR 1806-20. We find magnetar crusts that match observations for various magnetic field strengths, entrainment of the free neutron gas in the inner crust, and crust-core transition densities. We find that observations can be reconciled with smaller values of the symmetry energy slope parameter, L, if there is a significant amount of entrainment of the neutrons by the superfluid or if the crust-core transition density is large. We also find neutron star masses and radii which are in agreement with expectations from what is known about low-density matter from nuclear experiment. Matching observations with a field-free model we obtain the approximate values of M =1.35 Msun and R = 11.9 km. Matching observations using a model with the surface dipole field of SGR 1806-20 (B=2.4x10^15 G) we obtain the approximate values of M = 1.25 Msun and R = 12.4 km.

description: As an aid to the development of hydrogen separation membranes, we predict the temperature dependent phase diagrams using first principles calculations combined with thermodynamic principles. Our method models the phase diagram without empirical fitting parameters. By applying thermodynamic principles and solid solution models, temperature-dependent features of the Cu-Pd-S system can be explained, specifically solubility ranges for substitutions in select crystalline phases. Electronic densities of states calculations explain the relative favorability of certain chemical substitutions. In addition, we calculate sulfidization thresholds for the Pd-S2 system and activities for the Cu-Pd binary in temperature regimes where the phase diagram contains multiple solid phases.

description: This postgraduate thesis concerns the issue of ground sediments due to extensive water-pumping of the Messara aquifer and more specifically the Moires sub- basin.
Basic principles of hydrogeology are being examined as well as the mechanism of the development of ground sediments and analytical methods for their calculation. According to bibliography related with the Messara basin, data from previous research with the DInSAR method and the method of Special Trigonometry Altimetry are listed, as well as conclusions from the autopsy in the examined region.
Stratigraphy of the Moires subbasin and the water level of the aquifer are being simulated with the FEM program PLAXIS 2D and subsequently the expected ground sediments are being calculated. The simulation includes the well and the pressurized aquifer with the piezometry of the period 1981-2001, for which data is found from bibliography. The characteristics of ground sediments are obtained from the ydrogeological research of FAO (Food and Agriculture Organization of the United Nations) in early ‘70s. In addition, the ground sediments are being analytically calculated with Bouwer equations.
Finally, the assessment of the results of both methods (analytical and numerical) is summarised and a list of similar research topics as a future extension-contribution to this thesis is suggested.
Towards super-resolved terahertz microscopy for cellular imaging.

description: Biomedical imaging includes the use of a variety of techniques to study organs and tissues. Some of the possible imaging modalities are more spread at clinical level (CT, MRI, PET), while others, such as Light and Electron Microscopy are preferred in life sciences research. The choice of the imaging modalities can be based on the capability to study functional aspects of an organism, the delivered radiation dose to the patient, and the achievable resolution. In the last few decades, spectroscopists and imaging scientists have been interested in the use of terahertz (THz) frequencies (300 microns to 3 mm wavelength) due to the low photon energy associated (E∼1 meV, not causing breaking of the molecular bonds but still interacting with some vibrational modes) and the high penetration depth that is achievable. THz has been already adopted in security, quality control, and material sciences. However, the adoption of THz frequencies for biological and clinical imaging means to face, as a major limitation, the very scarce resolution associated with the use of such long wavelengths. To address this aspect and reconcile the benefit of minimal harmfulness for bioimaging with the achievable resolving power, many attempts have been made. This review summarises the state-of-the-art of THz imaging applications aimed at achieving super-resolution, describing how practical aspects of optics and quasi-optics may be treated to efficaciously implement the use of THz as a new low-dose and versatile modality in biomedical imaging and clinical research.

description: Using $J$ and $K_s$ band imaging obtained as part of the IMACS Cluster Building Survey (ICBS) we measure Sérsic indices for 2160 field and cluster galaxies at $0.31 < z < 0.54$. Using both mass- and magnitude-limited samples, we compare the distributions for spectroscopically determined passive, continuously starforming, starburst, and poststarburst systems and show that previously established spatial and statistical connections between these types extend to their gross morphologies. Outside of cluster cores, we find close structural ties between starburst and continuously starforming, as well as poststarburst and passive types, but not between starbursts and poststarbursts. These results independently support two conclusions presented in Paper II of this ICBS series (Dressler et al.): 1) most starbursts are the product of a non-disruptive triggering mechanism that is insensitive to global environment, such as minor-mergers; 2) starbursts and poststarbursts generally represent transient phases in the lives of "normal" starforming and quiescent galaxies, respectively, originating from and returning to these systems in closed "recycling" loops. In this picture, spectroscopically identified poststarbursts constitute a minority of all recently terminated starbursts, largely ruling-out the typical starburst as a quenching event in all but the densest environments.

Some logically weak Ramseyan theorems

description: We study four families of consequences of Ramsey's Theorem from the viewpoint of reverse mathematics. The first, which we call the Achromatic Ramsey Theorem, is from a partition relation introduced by Erdős, Hajnal and Rado: $ω\to [ω]^r_{c,\leq d}$, which asserts that for every $f: [ω]^r \to c$ there exists an infinite $H$ with $|f([H]^r)| \leq d$. The second and third are the Free Set Theorem and the Thin Set Theorem, which were introduced by Harvey Friedman. And the last is the Rainbow Ramsey Theorem. We show that, most theorems from these families are quite weak, i.e., they are strictly weaker than $\operatorname{ACA}_0$ over $\operatorname{RCA}_0$. Interestingly, these families turn out to be closely related. We establish the so-called strong cone avoidance property of most instances of the Achromatic Ramsey Theorem by an induction of exponents, then apply this and a similar induction to obtain the strong cone avoidance property of the Free Set Theorem. From the strong cone avoidance property of the Achromatic Ramsey Theorem and the Free Set Theorem, we derive the strong cone property of the Thin Set Theorem and the Rainbow Ramsey Theorem. It follws easily that a theorem with the strong cone avoidance property does not imply $\operatorname{ACA}_0$ over $\operatorname{RCA}_0$.

description: Quantum electrodynamics in a laser is formulated, in which the electron-laser interaction is exactly considered, while the interaction of an electron and a single photon is considered by perturbation. The formulation is applied to the electron-laser collisions. The effect of coherence between photons in the laser is therefore fully considered in these collisions. The possibility of $γ-$ray laser generation by use of this kind of collision is discussed.

description: The current thesis focuses on the chemical analysis and comparison of appropriately selected agricultural and municipal waste (liquid pig manure and solid coffee grounds) used in anaerobic continuous stirring reactor (CSTR), attempting to produce biogas. During the experiment, the hazard of the heavy metals of the nutrition was investigated by the X-Ray Fluorescence Spectroscopy (XRF). Moreover, the quality and quantity of produced biogas were analyzed by other methods and technics and the results of the experiment were compared by combining a mixture of liquid pig manure and solid coffee grounds with results of only liquid pig manure.
The first and theoretical part presents the process of anaerobic digestion and the feedstock introduced into the anaerobic reactor to complete the experiment with successful degradation of organic residues. Additionally, the first part presents the XRF and other methods and techniques which are used for biogas production. The second and experimental of the thesis describes the various experimental biogas production and XRF measurements. Finally, the third part depicts the conclusions and suggestions for finding even more efficient materials that can be used in the future.

description: In Germany, the productivity of professional services, a sector dominated by micro and small firms, declined by 40 percent between 1995 and 2014. This productivity decline also holds true for professional services in other European countries. Using a German firm-level dataset of 700,000 observations between 2003 and 2017, we analyze this largely uncovered phenomenon among professional services, the 4th largest sector in the EU15 business economy, which provide important intermediate services for the rest of the economy. We show that changes in the value chain explain about half of the decline and the increase in part-time employment is a further minor part of the decline. In contrast to expectations, the entry of micro and small firms, despite their lower productivity levels, is not responsible for the decline. We also cannot confirm the conjecture that weakening competition allows unproductive firms to remain in the market.

description: We measured the ultrasonic properties and the microstructure of two-phase binary mixtures of the ice-ammonia partial melt system, which was selected based on its importance for numerous planetary bodies. The equilibrium microstructure of ice-ammonia melt was examined using a light microscope within a cold room. The measured median dihedral angle between the solid and melt at 256 K is approximately 63deg, with a broad distribution of observed angles. P-wave velocities in the partially molten samples were measured as a function of temperature and composition. We compare the results of this study to those of other potential binary systems by normalizing the datasets using a vertical lever and articulating the potential effects on the mechanical behavior and transport capabilities of partially molten ice in icy satellites.

description: We present a study of weak lensing shear measurements for simulated galaxy images at radio wavelengths. We construct a simulation pipeline into which we can input galaxy images of known ellipticity, and with which we then simulate observations with eMERLIN and the international LOFAR array. The simulations include the effects of the CLEAN algorithm, uv sampling, observing angle, and visibility noise, and produce realistic restored images of the galaxies. We apply a shapelet-based shear measurement method to these images and test our ability to recover the true source ellipticities. We model and deconvolve the effective PSF, and find suitable parameters for CLEAN and shapelet decomposition of galaxies. We demonstrate that ellipticities can be measured faithfully in these radio simulations, with no evidence of an additive bias and a modest (10%) multiplicative bias on the ellipticity measurements. Our simulation pipeline can be used to test shear measurement procedures and systematics for the next generation of radio telescopes.

Για να επιτευχθεί αυτό χρησιμοποιήθηκε ένας συνδυασμός τεχνικών και αναλύσεων, όπως η περιθλασιμετρία ακτινών Χ, η φασματογραφία μάζας επαγωγικά συζευγμένου πλάσματος και η φασματοσκοπία ατομικής απορρόφησης. Επιπλέον, εξετάστηκαν μέθοδοι περιορισμού του φαινομένου των επικαθίσεων/επισκωριώσεων στους κλιβάνους καύσης, όπως η εκχύλιση των καυσίμων με νερό και η μίξη τους με υπολείμματα φυτικής προέλευσης.
Τα αποτελέσματα έδειξαν ότι το σύνολο των καυσίμων ήταν πλούσιο σε ασβέστιο, φώσφορο, πυρίτιο και μαγνήσιο, αλλά και σε ιχνοστοιχεία χαλκού και ψευδαργύρου. Από την μίξη των καυσίμων, προέκυψαν μίγματα με τάση επικαθίσεων/επισκωριώσεων ανάμεσα σε αυτή των συστατικών τους. Επιπλέον, με βάση τα αποτελέσματα, αυξημένες αναμένονται οι επικαθίσεις από την καύση των αστικών στερεών απορριμμάτων, των κρεατάλευρων βιομηχανίας χοίρων και των στέμφυλων. Η εκχύλιση των δειγμάτων έπαιξε σημαντικό ρόλο στη μείωση προβληματικών στοιχείων όπως το κάλιο, το νάτριο, ο φώσφορος, το θείο και το χλώριο, με αποτέλεσμα να μειωθεί σημαντικά η τάση επικαθίσεων/επισκωριώσεων των εκχυλισμένων δειγμάτων.

description: Η διαδικασία παρακολούθησης-τεκμηρίωσης των δεδομένων οπτικής εστίασης (Eye / Gaze Tracking) έχει αποδειχθεί εξαιρετικά χρήσιμη για την κατανόηση των γνωσιακών (Cognitive) διεργασιών των πιλότων κατά τη διάρκεια της πτήσης και αποτελεί το αντικείμενο έρευνας στην παρούσα εργασία. Για το λόγο αυτό, αναπτύχθηκε κατάλληλη, πειραματική διάταξη που επιτρέπει την καταγραφή δεδομένων οπτικής εστίασης του εκπαιδευόμενου πιλότου, σε εξομοιωτή αεροσκάφους υψηλών επιδόσεων F-16. Παράλληλα, αναπτύχθηκε μια πρωτότυπη, γρήγορη και φιλική προς τον χρήστη διαδικασία βαθμονόμησης (Calibration Procedure) του ανιχνευτή οπτικής εστίασης.
Επιπλέον, αξιοποιώντας την εμπειρία του συντάκτη της παρούσας εργασίας ως Εκπαιδευτή Πτήσεων και Εξομοιωτή στα F-16, αναπτύχθηκε η μεθοδολογία υπολογισμού δύο νέων δεικτών επεξεργασίας και ερμηνείας των δεδομένων εστιάσεων βλέμματος: του Revision Interval και του Level 1 SA Estimate που συμβάλουν στην επεξεργασία, ερμηνεία και παρουσίαση των δεδομένων βλέμματος του πιλότου. Επιπρόσθετα, αναπτύχθηκε εφαρμογή λογισμικού που καταγράφει, αναλύει και παρουσιάζει σε πραγματικό χρόνο (Real Time Data Analysis) τα δεδομένα εστίασης βλέμματος, ώστε να αξιοποιούνται από τον Εκπαιδευτή τόσο κατά την διάρκεια της εκπαιδευτικής αποστολής, όσο και συγκεντρωτικά μετά από την ολοκλήρωση της εικονικής πτήσης (Post Flight Data Analysis), με σκοπό την βελτίωση της εκπαίδευσης στους εξομοιωτές πτήσης.
description: The Eye / Gaze Tracking - Documentation process has proven to be extremely useful for understanding pilot’s in-flight cognitive processes and is the research subject in the present thesis. For this reason, a suitable experimental setup was developed that allows the recording of pilot’s gaze data in a high performance, F-16 aircraft simulator. Along with that, an original, fast and user-friendly calibration procedure of the Eye Tracker was developed as well.
Additionally, the calculation methodologies of two new indicators were devised by utilizing the author’s experience as an F-16 Flight and Simulator Instructor: Revision Interval and Level 1 SA Estimate, aiming to contribute in to the processing, interpretation and presentation of pilot’s gaze data. Furthermore, a software application has been developed that captures, analyzes and presents in real-time the students gaze data, so that they can be used by the instructor during the simulated mission execution, but also as a post flight, collective gaze data analysis for debriefing utilization, aimed to improve the training in flight simulators.

description: A method to construct fractal surfaces by recurrent fractal curves is provided. First we construct fractal interpolation curves using a recurrent iterated functions system(RIFS) with function scaling factors and estimate their box-counting dimension. Then we present a method of construction of wider class of fractal surfaces by fractal curves and Lipschitz functions and calculate the box-counting dimension of the constructed surfaces. Finally, we combine both methods to have more flexible constructions of fractal surfaces.

title: This is the tenour of my waking dream: A critical study of Shelley's "The Triumph of Life"
Creators: name: Wu, Ya-Feng
Publisher: name: University of Glasgow
Year: 1995
Subjects: subject: English literature.

description: In this doctoral thesis I seek to offer a critical reading of Shelley's last major endeavour, 'The Triumph of Life', through a thorough discussion of the related themes and structures in his earlier works. The thesis first traces Shelley's mediation between his two most abiding inspirations, his 'passion for reforming the world' and his private desire to retreat. This mediation takes the form of a grand dialogue with his predecessors and contemporaries, such as Wordsworth and Byron, a dialogue in which Shelley tries to define his own position through the clashes of opposing viewpoints. A rich intertextuality as a result of the dialogue offers an analogue for Shelley's probing into the psyche through the concentric framework of reverie. His delving into the psychic realm always at the same time opens out into a reflection on the poet's role in history, which is a reflection recurrently dramatised in the figure of history-making, triumphal processions. All these discussions lead to a reading of The Triumph of Life' which is structured around the dialogue with the composite figure, Rousseau. In this vision, Shelley engages in a comprehensive investigation into the core of Western civilisation. He seeks to reformulate his earlier visions and to re-orient Dante's trilogy by maintaining his position as a purgatorial exile, where he holds on to a vision which for him is not infernal. This position is adumbrated in the unaccomplished critique of 'self-centred seclusion' in Alastor, and is achieved precariously in 'The Triumph of Life', because of the latter's unfinished state. 'The Triumph of Life' has been variously represented by commentators as either a palinode of Shelley's earlier endeavours or as a suggestion of a new direction in his idealism. The thesis attempts to show that it is the appropriate fulfilment of a career in which each of the major poems confronts its own palinode but at the same time maintains an idealism that forever refuses to compromise.

Curious Cases of Copyrightability Before the Copyright Office

description: Administering the national registration program is a core function of the Copyright Office. In most cases, determining copyrightability of a claim submitted for registration is simple, and the Office does not need to correspond over or otherwise belabor the mine run of applications to determine whether a work possesses the creative spark necessary to register a copyright interest. As the Supreme Court has noted, “the requisite level of creativity is extremely low,” and “[t]he vast majority of works make the grade quite easily.” Sometimes, however, applied-for works invoke modes of authorship that test that standard, and the Copyright Office must resolve these claims. Applicants may contest refusals to register claims, culminating in the ability to lodge a final administrative appeal to the Copyright Office Review Board. As a member of that Board for the past four years, I’ve seen the Office apply established principles of copyrightability to a variety of dynamic claims.

description: Due to the wave nature of light, optical microscopy has a lower-bound lateral resolution limit of approximately half of the wavelength of visible light, i.e., within the range of 200 to 350 nm. Fluorescence Fluctuation based Super Resolution Microscopy (FF-SRM) is a term used to encompass a collection of image analysis techniques which rely on the statistical processing of temporal variations of the fluorescence signal. FF-SRM aims to reduce the uncertainty of the location of fluorophores within an image, often improving spatial resolution to several tens of nanometers. FF-SRM is suitable for live-cell imaging due to its compatibility with most fluorescent probes and relatively simple instrumental and experimental requirements, which are mostly camera-based epifluorescence instruments. Each FF-SRM approach has strengths and weaknesses, which depend directly on the underlying statistical principles through which enhanced spatial resolution is achieved. In this review, the basic concepts and principles behind a range of FF-SRM methods published to date are described. Their operational parameters are explained and guidance for its selection is provided. This article is protected by copyright. All rights reserved.
The Torelon spectrum and the world-sheet Axion

description: We present a major update on the spectrum of the closed flux-tube in D=3+1 SU(N) gauge theories. Namely, we calculate the excitation spectrum of a confining flux-tube which winds around a spatial torus as a function of its length l, for short as well as long tubes. We do so for N=3,5,6 and two different values of the lattice spacing. Our states are characterised by the quantum numbers of spin J, transverse parity \(P_{\perp}\), longitudinal parity \(P_{\parallel}\) as well as by the longitudinal momentum \(p_{\parallel}\). Our extended basis of operators used in combination with the generalized eigenvalue method enables us to extract masses for all irreducible representations characterised by \( \{ J,P_{\perp},P_{\parallel} \}\). We confirm that most of the low-lying states are well described by the spectrum of the Goddard–Goldstone–Rebbi–Thorn string. In addition we provide strong evidence, that in addition to string like states, massive modes exist on the bulk. More precisely the ground state with quantum numbers \(J^{P_{\perp}, P_{\parallel}}=0^{--}\) exhibits a behaviour which is in agreement with the interpretation of being an axion on the wordsheet of the flux-tube. This state arises from a topological interaction term included in the effective world-sheet action. In addition we observe that the second excited state with \(J^{P_{\perp}, P_{\parallel}}=0^{++}\) behaves as a massive mode with mass twice that of the axion.

Highway Art Policy Revisited: Rethinking Transfers of Copyright Ownership in State-Owned Transportation Artwork

subject: Copyright--Transfer

description: In 2016, the California Department of Transportation ("Caltrans") revised its policy standards with respect to the intellectual property rights of artists who create works of public art installed within the state highway system. While Caltrans had previously allowed artists to keep their copyrights subject to a nonexclusive license of certain reproduction rights to the state, the 2016 policy (the “Transportation Art Policy”) requires artists to assign their “entire rights, title and interest in” such works of art to Caltrans, including their “common law and federal copyright ownership rights.” The artist must execute a copyright assignment and transfer agreement, which Caltrans must approve, before the art is installed. This requirement exists even though the policy assumes that certain local “public agencies,” not the state of California itself, will be responsible for commissioning works of art; the policy directs the commissioning agency for a given work of art to also sign onto the assignment and transfer agreement. This Note argues that state policies that, like Caltrans’, require a transfer of copyright in works of public art are ill-fitted to their purposes, and that the goals of copyright law are better served by alternative contractual arrangements. In Part I, I provide an overview of the legal landscape in the United States with respect to transfers of copyright ownership, visual artists’ moral rights, and public art commissions. In Part II, I outline the substance of Caltrans’ Transportation Art Policy and the possible justifications for its 2016 revision, and then show why the policy is both a poor fit for those presumptive objectives and an unwarranted burden on stakeholders. Finally, in Part III, I discuss alternatives to public art policies that require copyright transfer. I argue that states or state agencies seeking to own public artwork should, as Caltrans once did, allow artists to retain copyright provided that they grant the state a nonexclusive license for reasonable public uses. The advantage of such an approach—which many other states already employ—is that it offers reasonable protection for the state’s legitimate interests in avoiding liability and enforcing the copyright, without the attendant harms to artistic creativity and to the public.
