description: We present results from Chandra HETGS (250 ks over two epochs) and XMM-Newton EPIC and RGS (60 ks) observations of NGC 2110, which has been historically classified as a Narrow Emission Line Galaxy galaxy. Our results support the interpretation that the source is a Seyfert 2 viewed through a patchy absorber. The nuclear X-ray spectrum of the source is best described by a power law of photon index $Γ$ ~1.7, modified by absorption from multiple layers of neutral material at a large distance from the central supermassive black hole. We report the strong detections of Fe K$α$ and Si K$α$ lines, which are marginally resolved with the Chandra HETGS, and we constrain the emission radius of the fluorescing material to >1 pc. There is some evidence for modest additional broadening at the base of the narrow Fe K$α$ core with a velocity ~4500 km s$^{-1}$. We find tentative evidence for ionized emission (O VIII Ly $α$, an O VIII RRC feature, and possibly a Ne IX forbidden line) in the Chandra MEG and XMM-Newton RGS spectra, which could be associated with the known extended X-ray emission that lies ~160 pc from the nucleus. We suggest that the $10^{23}$ cm$^{-2}$ partially covering absorber originates in broad-line region clouds in the vicinity of the AGN, and that the $3\times10^{22}$ cm$^{-2}$ coverer is likely to have a more distant origin and have a flattened geometry in order to allow the small-scale radio jet to escape.

description: The C*-algebra qC is the smallest of the C*-algebras qA introduced by Cuntz in the context of KK-theory. An important property of qC is the natural isomorphism of K0 of D with classes of homomorphism from qC to matrix algebras over D. Our main result concerns the exponential (boundary) map from K0 of a quotient B to K1 of an ideal I. We show if a K0 element is realized as a homomorphism from qC to B then its boundary is realized as a unitary in the unitization of I. The picture we obtain of the exponential map is based on a projective C*-algebra P that is universal for a set of relations slightly weaker than the relations that define qC. A new, shorter proof of the semiprojectivity of qC is described. Smoothing questions related the relations for qC are addressed.

A Systematic Study of the Final Masses of Gas Giant Planets

description: We construct an analytic model for the rate of gas accretion onto a planet embedded in a protoplanetary disk as a function of planetary mass, disk viscosity, disk scale height, and unperturbed surface density in order to study the long-term accretion and final masses of gas giant planets. We first derive an analytical formula for surface density profile near the planetary orbit from considerations of the balance of force and the dynamical stability. Using it in the empirical formula linking surface density with gas accretion rate that is derived based on hydrodynamic simulations of Tanigawa and Watanabe (2002, ApJ 586, 506), we then simulate the mass evolution of gas giant planets in viscously-evolving disks. We finally determine the final mass as a function of semi-major axis of the planet. We find that the disk can be divided into three regions characterized by different processes by which the final mass is determined. In the inner region, the planet grows quickly and forms a deep gap to suppress the growth by itself before disk dissipation. The final mass of the planet in this region is found to increase with the semi-major axis in a similar way to the mass given by the viscous condition for gap opening, but the former is larger by a factor of approximately 10 than the latter. In the intermediate region, viscous diffusion of the disk gas limits the gas accretion before the planet form a deep gap. The final mass can be up to the disk mass, when disk viscous evolution occurs faster than disk evaporation. In the outer region, planets capture only tiny amounts of gas within the lifetime of the disk to form Neptune-like planets. We derive analytic formulae for the final masses in the different regions and the locations of the boundaries, which are helpful to gain a systematic understanding of the masses of gas giant planets.

description: We study when certain properties of Banach algebras are stable under ultrapower constructions. In particular, we consider when every ultrapower of $\mc A$ is Arens regular, and give some evidence that this is if and only if $\mc A$ is isomorphic to a closed subalgebra of operators on a super-reflexive Banach space. We show that such ideas are closely related to whether one can sensibly define an ultrapower of a dual Banach algebra. We study how tensor products of ultrapowers behave, and apply this to study the question of when every ultrapower of $\mc A$ is amenable. We provide an abstract characterisation in terms of something like an approximate diagonal, and consider when every ultrapower of a C$^*$-algebra, or a group $L^1$-convolution algebra, is amenable.

description: Finite size effect on the antiferromagnetic transition temperature, TN, of Co3O4 nanoparticles of 75, 35, and 16 nm in diameter, has been investigated. The AFM transition point, TN, reduces with the decreasing diameter, d. Along with the results from the previous experiments on the Co3O4 nanoparticles of 8 and 4.3 nm, the variation of TN with d appears to follow the finite size relation. According to the scaling behavior, the shift exponent is determined as λ= 1.4 \pm 0.4, the correlation length, \ksi_0 = 3.0 \pm 0.3 nm, and the bulk Neel temperature, TN(\infint) = 38.6 \pm 0.7 K.

We show that $a^2+Q^2=M^2$ always holds provided that a continuous sequence of spacetimes can be identified, leading from the Kerr-Newman solution in electrovacuum to the solution in question. The quantity $a=J/M$ is the black hole's intrinsic angular momentum per unit mass, $Q$ its electric charge and $M$ the well known black hole mass parameter introduced by Christodoulou and Ruffini.

description: The first moment of longitudinal and transverse spin densities of quarks in the nucleon are calculated in a light-front constituent quark model for the different cases of quark and nucleon polarization. Significant distortions are found for the transverse spin densities. In particular the Sivers function is predicted with opposite sign for up and down quarks and the Boer-Mulders function is predicted large and negative for both up and down quarks, in agreement with lattice calculations. Quite a different spin distribution is obtained for up and down quarks in the cases of quarks and proton transversely or longitudinally polarized in the same direction.

description: The present study discusses the topic of the assignment of administrative task to private individuals. The study begins with the conceptual definition of the terms that make up its title and, specifically, the terms of the assignment, the administrative task and that of (private) individuals, while special emphasis is also given on the concept of public service, which holds a central place for the issue under consideration. After the analysis of these critical terms, the study examines some of the most important and common in practice cases of the assignment of administrative task to private individuals. More specifically, in a first part are presented the cases of administrative task assignment in the context of the provision administration, which constitute the most classic case of administrative task assignment to individuals, while, in a second part are presented the cases of administrative task assignment in the context of restrictive administration, which are more and more frequently encountered in the modern administrative practice. The study concludes with the examination of the constitutional limits and commitments to which the legislator is subject to when assigning administrative task to private individuals

description: Reconstructing the KAM dynamics diagram of Hamiltonian system from the time series of a limited number of parameters is an outstanding question in nonlinear science, especially when the Hamiltonian governing the system dynamics are unknown. Here, we demonstrate that this question can be addressed by the machine learning approach knowing as reservoir computer (RC). Specifically, we show that without prior knowledge about the Hamilton's equations of motion, the trained RC is able to not only predict the short-term evolution of the system state, but also replicate the long-term ergodic properties of the system dynamics. Furthermore, by the architecture of parameter-aware RC, we also show that the RC trained by the time series acquired at a handful parameters is able to reconstruct the entire KAM dynamics diagram with a high precision by tuning a control parameter externally. The feasibility and efficiency of the learning techniques are demonstrated in two classical nonlinear Hamiltonian systems, namely the double-pendulum oscillator and the standard map. Our study indicates that, as a complex dynamical system, RC is able to learn from data the Hamiltonian.

description: Riroriro is a Python package to simulate the gravitational waveforms of binary mergers of black holes and/or neutron stars, and calculate several properties of these mergers and waveforms, specifically relating to their observability by gravitational wave detectors. The gravitational waveform simulation of Riroriro is based upon the methods of Buskirk and Babiuc-Hamilton (2019), a paper which describes a computational implementation of an earlier theoretical gravitational waveform model by Huerta et al. (2017), using post-Newtonian expansions and an approximation called the implicit rotating source to simplify the Einstein field equations and simulate gravitational waves. Riroriro's calculation of signal-to-noise ratios (SNR) of gravitational wave events is based on the methods of Barrett et al. (2018), with the simpler gravitational wave model Findchirp (Allen et al. (2012)) being used for comparison and calibration in these calculations.

description: We report the transport of ultracold atoms with optical tweezers in the non-adiabatic regime, i.e. on a time scale on the order of the oscillation period. We have found a set of discrete transport durations for which the transport is not accompanied by any excitation of the centre of mass of the cloud. We show that the residual amplitude of oscillation of the dipole mode is given by the Fourier transform of the velocity profile imposed to the trap for the transport. This formalism leads to a simple interpretation of our data and simple methods for optimizing trapped particles displacement in the non-adiabatic regime.

Construction of galactose assimilating, carotenoid producing yeasts by protoplast fusion
Creators: name: Hansen, Christine S.
Publisher: name: University of British Columbia
Year: 2010

description: Protoplasts were prepared from two yeast strains P. rhodozyma (ATCC 24202) and K. fragilis (ATCC 8455). Protoplasts prepared from P. rhodozyma were facilitated by prior growth of the cells in a media containing S-(2-aminoethyl)-L-cysteine. Protoplasts from these two yeast genera were fused either by the use of electrofusion or polyethylene glycol treatment. Stable carotenoid producing cell lines were selected by growth at 30°C on yeast nitrogen base plus galactose. Selected single fusants display taxonomic characteristics common to both genera with a cellular morphology and a carotenoid composition similar to that of P. rhodozyma.

Η Κοινότητα διοικούνταν κυρίως από δύο σωματεία την Δημογεροντία που είχε διοικητικά καθήκοντα και την Εφορεία η οποία διευθετούσε τα οικονομικά της Κοινότητας. Η Δημογεροντία είχε 12 μέλη και η Εφορεία 5 μέλη. Τα σωματεία εκείνα εκλέγονταν από την Αντιπροσωπία της πόλης η οποία εκλέγονταν από τις ενορίες της. Πρόεδρος όλων αυτών των σωματείων ήταν ο εκάστοτε Μητροπολίτης της Ξάνθης. Τα μέλη των σωματείων δηλαδή οι δημογέροντες ήταν άνδρες άνω των 25 ετών. Μετά την απελευθέρωση της Ξάνθης από την βουλγαρική κατοχή το 1919 η πόλη διατέλεσε για 8 μήνες περίπου υπό Διασυμμαχική Διοίκηση η οποία ήταν μια μεταβατική περίοδο για να αποδοθεί η Δ. Θράκη στο ελληνικό κράτος. Η Διασυμμαχική Διοίκηση χρησιμοποίησε την Δημογεροντία ως διοικητικό της όργανο και τις ανέθεσε θρησκευτικά και εκκλησιαστικά καθήκοντα. Τα καθήκοντα εκείνα η Δημογεροντία τα διατήρησε και μετά την ένταξή της στο ελ-ληνικό κράτος συνεπικουρώντας τις τοπικές διοικητικές αρχές στον τομέα της εκπαίδευ-σης, μέχρι το 1924 που η κυβέρνηση αποφάσισε να εφαρμόσει τον νόμο διάλυσης των Δημογεροντιών για τις Νέες Χώρες. Από τότε και μέχρι το πέρας της λειτουργίας της τον Φεβρουάριο του 1926 διένυσε μια μεταβατική περίοδο από το Κοινοτικό σύστημα σ’ εκείνο των Ανώτερων Ενοριακών Αντιπροσωπιών.
description: The aim of this doctoral thesis is the study of organization and work of the Orthodox Greek Community of Xanthi during 1919-1926. Τhe Community was governed by two clubs the Elder-ship that had administrative duties and the Revenue that had economical duties. The Elder-ship had 12 members and the Revenue had 5 members. The members of those clubs were elected from the Representatives of the city that was elected from every parish of Xanthi. The members of those clubs should be males over 25 years of age and the president of all the clubs was the Metropolitan of Xanthi. After the liberation of Xanthi from the Bulgarian occupation in 1919 by the end of World War I, the city and the W. Thrace for almost 8 months was under the control of allied forces, a regime called Inter-Allied Thrace. That regime used the Elder-ship for administrative purposes with responsibilities on educational and religious issues. After the full accession of W. Thrace to Greek territory, Elder-ship kept those duties and contributed the local authorities mainly in educational issues. Greek authorities issue law that provided the end of function of elder-ships. That law applied to Xanthi in 1924 but elder-ship of Xanthi continued its function until February 1926. That was a necessary adjustment period because the transition to the next form of ecclesiastical local government, the parish councils was not easy.
Isoflurane induced impairment of synaptic transmission in hippocampal neurons of the guinea pig in vitro
Creators: name: Miu, Peter
Publisher: name: University of British Columbia
Year: 2010

description: The effects of anaesthetic applications of isoflurane on 82 CA₁ neurons were studied in in vitro preparations (guinea pigs) using intracellular recording techniques. Various parameters of their excitability such as membrane electrical properties, action potentials and their afterhyperpolarizing potentials as well as synaptic transmission were determined during bath perfusion of clinically relevant concentrtaions of isoflurane. Concentrations of isoflurane were detected in the bath with ¹⁹fluorine nuclear magnetic resonance techniques, and were found to range between 0.02 and 0.3 mM. No consistent effects on the membrane properties were observed. When synaptic activity was blocked by tetrodotoxin, isoflurane induced a hyperpolarization (3-5 mV) without affecting input conductance which was computed from the voltage responses to injections of hyperpolarizing current pulses and the slopes of current-voltage relations for each cell. Responses to depolarizing pulses revealed that the threshold, amplitude and duration of the evoked spikes were not greatly altered, although repetitive spike firing was suppressed in a dose-dependent manner by isoflurane. Similarly, the amplitude and duration of the long-lasting hyperpolarizations following the elicitation of multiple (4 or 5) spikes were reduced in a reversible and dose-dependent manner. Reductions in amplitude and duration of excitatory and inhibitory postsynaptic potentials evoked by electrical stimulation of stratum radiatum were observed; these effects also were strictly dependent on the dose, as well as on duration of the application. These investigations have revealed that isoflurane interferes with synaptic transmission in the hippocampal slice preparation and suggest that presynaptic actions on transmitter release, in addition to postsynaptic effects

description: This dissertation studied machine learning and computer vision methods for semantic image and video analysis. More specifically, the problems of face recognition, human action recognition, object recognition and video summarization were studied as classification problems, along with the problems of privacy protection and robustness to adversarial attacks. Supervised, semi-supervised and deep learning algorithms were proposed, in the context of one-class classification, multiclass classification, adversarial attacks and defenses. Novel methodologies that provide increased classification performance were developed, attributed to the introduction of additional regularization terms to the optimization problems of well-known learning algorithms, in order to exploit geometric training data relationships. Finally, a novel adversarial attack methodology that introduces privacy protection criteria was developed, along with a mechanism that increases the classification model robustness against adversarial attacks, by incorporating a novel neural network layer based on one-class classifiers.

description: Usually, opinion formation models assume that individuals have an opinion about a given topic which can change due to interactions with others. However, individuals can have different opinions in different topics and therefore n-dimensional models are best suited to deal with these cases. While there have been many efforts to develop analytical models for one dimensional opinion models, less attention has been paid to multidimensional ones. In this work, we develop an analytical approach for multidimensional models of continuous opinions where dimensions can be correlated or uncorrelated. We show that for any generic reciprocal interactions between agents, the mean value of initial opinion distribution is conserved. Moreover, for positive social influence interaction mechanisms, the variance of opinion distributions decreases with time and the system converges to a delta distributed function. In particular, we calculate the convergence time when agents get closer in a discrete quantity after interacting, showing a clear difference between correlated and uncorrelated cases.

description: The availability of efficient photon sources with specific properties is important for quantum-technological applications. However, the realization of such photon sources is often challenging and hence alternative perspectives that suggest new means to enhance desired properties while suppressing detrimental processes are valuable. In this work we highlight that ab-initio simulations of coupled light-matter systems can provide such new avenues. We show for a simple model of a quantum ring that by treating light and matter on equal footing we can create and enhance novel pathways for down-conversion processes. By changing the matter subsystem as well as the photonic environment in experimentally feasible ways, we can engineer hybrid light-matter states that enhance at the same time the efficiency of the down-conversion process and the non-classicality of the created photons. Furthermore we show that this also leads to a faster down-conversion, potentially avoiding detrimental decoherence effects.

description: Several theories have been proposed to explain the development of harmful algal blooms (HABs) produced by the toxic dinoflagellate \emph{Karenia brevis} on the West Florida Shelf. However, because the early stages of HAB development are usually not detected, these theories have been so far very difficult to verify. In this paper we employ simulated \emph{Lagrangian coherent structures} (LCSs) to trace the early location of a HAB in late 2004 before it was transported to an area where it could be detected by satellite imagery, and then we make use of a population dynamics model to infer the factors that may have led to its development. The LCSs, which are computed based on a surface flow description provided by an ocean circulation model, delineate past and future histories of boundaries of passively advected fluid domains. The population dynamics model determines nitrogen in two components, nutrients and phytoplankton, which are assumed to be passively advected by the simulated surface currents. Two nearshore nutrient sources are identified for the HAB whose evolution is found to be strongly tied to the simulated LCSs. While one nutrient source can be associated with a coastal upwelling event, the other is seen to be produced by river runoff, which provides support to a theory of HAB development that considers nutrient loading into coastal waters produced by human activities as a critical element. Our results show that the use of simulated LCSs and a population dynamics model can greatly enhance our understanding of the early stages of the development of HABs.

description: The identification of protein-ligand interaction plays a key role in biochemical research and drug discovery. Although deep learning has recently shown great promise in discovering new drugs, there remains a gap between deep learning-based and experimental approaches. Here we propose a novel framework, named AIMEE, integrating AI Model and Enzymology Experiments, to identify inhibitors against 3CL protease of SARS-CoV-2, which has taken a significant toll on people across the globe. From a bioactive chemical library, we have conducted two rounds of experiments and identified six novel inhibitors with a hit rate of 29.41%, and four of them showed an IC50 value less than 3 μM. Moreover, we explored the interpretability of the central model in AIMEE, mapping the deep learning extracted features to domain knowledge of chemical properties. Based on this knowledge, a commercially available compound was selected and proven to be an activity-based probe of 3CLpro. This work highlights the great potential of combining deep learning models and biochemical experiments for intelligent iteration and expanding the boundaries of drug discovery.

description: In this paper we work out a multiverse scenario whose physical characteristics enable us to advance the following the conjecture that whereas the physics of particles and fields is confined to live in the realm of the whole multiverse formed by finite-time single universes, that for our observable universe must be confined just in one of the infinite number of universes of the multiverse when such a universe is consistently referred to an infinite cosmic time. If this conjecture is adopted then some current fundamental problems that appear when one tries to make compatible particle physics and cosmology- such as that for the cosmological constant, the arrow of time and the existence of a finite proper size of the event horizon- can be solved.

description: Τα τελευταία χρόνια η τεχνολογία εισβάλει ολοένα και περισσότερο στη ζωή μας με ποικίλους τρόπους. Το ζητούμενο ωστόσο είναι οι νέες τεχνολογίες να συνάδουν κατά το μεγαλύτερο δυνατό με την προστασία του περιβάλλοντος. Ένας τρόπος για να συμβεί αυτό είναι μέσα από την ευαισθητοποίηση των πολιτών πάνω σε περιβαλλοντικά ζητήματα που απασχολούν την κοινή γνώμη παγκοσμίως. Πολλές ψηφιακές εφαρμογές που έχουν δημιουργηθεί, με τη συνεχή τεχνολογική εξέλιξη, αποσκοπούν επομένως στην σωστή ενημέρωση των πολιτών όλων των ηλικιακών βαθμίδων και την ίδρυση περιβαλλοντικής συνείδησης. Σκοπός της παρούσας μεταπτυχιακής διατριβής, ύστερα από μία βιβλιογραφική ανασκόπηση σχετικά με την περιβαλλοντική ευαισθητοποίηση και τις διάφορες εφαρμογες, είναι η αναζήτηση, η καταγραφή, ανάλυση και σύγκριση ψηφιακών εφαρμογών που έχουν δημιουργηθεί με σκοπό την περιβαλλοντική ευαισθητοποίηση των πολιτών. Η καταγραφή των ψηφιακών εφαρμογών περιλαμβάνει χαρακτηριστικά και στοιχεία της κάθε μεμονωμένης εφαρμογής όπως για παράδειγμα η χώρα προέλευσης τους και το εύρος ηλικίας στο οποίο αναφέρονται. Επιπλέον καταγράφεται ο τρόπος συμβολής τους στην αφύπνιση της περιβαλλοντικής συνείδησης
description: In recent years, technology has invaded our lives more and more in various ways. What is required, however, is that new technologies be as consistent as possible with the protection of the environment. One way to do this is by raising public awareness of environmental issues that are of global concern. Many digital applications that have been created, with the continuous technological development, therefore aim at the proper information of the citizens of all ages and the establishment of environmental awareness. The purpose of this master's thesis, after a literature review on environmental awareness and the various applications, is the search, recording, analysis and comparison of digital applications created for the purpose of environmental awareness of citizens. The recording of digital applications includes features and elements of each individual application such as their country of origin and the age range to which they refer. In addition, the way they contribute to the awakening of environmental consciousness is recorded
More than Exception: Categories and the Problem of “Nature” in the Ruhr
Creators: name: Angelo, Hillary
Publisher: name: Moving the Social
Year: 2014

description: This essay reflects on the conceptualisation of the Ruhr region as an urban and historical research object in English-language scholarship and the effects of this understanding on historical social analysis. It focuses particularly on how signs of “nature” – in the form of green space incorporated into industrial workers’ colony housing (Arbeitersiedlungen) around the turn of the last century – have been seen as “exceptions” in an industrial environment, and are subsequently interpreted as indicators of anti-modern values or pre-industrial ideals. I argue that this is the result of the production-centric frame that has dominated urban and historical analysis in the Ruhr, and suggest an alternative interpretation. These are new uses of green space that emerged through industrialisation and urbanisation, and that reflect a modern sensibility towards “nature”: one in which these material referents become legible as vehicles for social goods.

Lyman Alpha Emitters in the Hierarchically Clustering Galaxy Formation

description: We present a new theoretical model for the luminosity functions (LFs) of Lyman alpha (Lya) emitting galaxies in the framework of hierarchical galaxy formation. We extend a semi-analytic model of galaxy formation that reproduces a number of observations for local and high-z galaxies, without changing the original model parameters but introducing a physically-motivated modelling to describe the escape fraction of Lya photons from host galaxies (f_esc). Though a previous study using a hierarchical clustering model simply assumed a constant and universal value of f_esc, we incorporate two new effects on f_esc: extinction by interstellar dust and galaxy-scale outflow induced as a star formation feedback. It is found that the new model nicely reproduces all the observed Lya LFs of the Lya emitters (LAEs) at different redshifts in z ~ 3-6. Especially, the rather surprisingly small evolution of the observed LAE Lya LFs compared with the dark halo mass function is naturally reproduced. Our model predicts that galaxies with strong outflows and f_esc ~ 1 are dominant in the observed LFs. This is also consistent with available observations, while the simple universal f_esc model requires f_esc << 1 not to overproduce the brightest LAEs. On the other hand, we found that our model significantly overpredicts LAEs at z > 6, and absorption of Lya photons by neutral hydrogen in intergalactic medium (IGM) is a reasonable interpretation for the discrepancy. This indicates that the IGM neutral fraction x_HI rapidly evolves from x_HI << 1 at z < 6 to a value of order unity at z ~ 6-7, which is broadly consistent with other observational constraints on the reionization history.

description: Braided-Lie bialgebras have been introduced by Majid, as the Lie versions of Hopf algebras in braided categories. In this paper we extend previous work of Majid and of ours to show that there is a braided-Lie bialgebra associated to each inclusion of Kac-Moody bialgebras. Doing so, we obtain many new examples of infinite-dimensional braided-Lie bialgebras. We analyze further the case of untwisted affine Kac-Moody bialgebras associated to finite-dimensional simple Lie algebras. The inclusion we study is that of the finite-type algebra in the affine algebra. This braided-Lie bialgebra is isomorphic to the current algebra over the simple Lie algebra, now equipped with a braided cobracket. We give explicit expressions for this braided cobracket for the simple Lie algebra $sl_3$.

description: This paper describes my personal appreciation of some of Tini Veltman's great research achievements and how my own research career has followed the pathways he opened. Among the topics where he has been the most influential have been the pursuit and study of the Higgs boson and the calculation of radiative corrections that enabled the masses of the top quark and the Higgs boson to be predicted ahead of their discoveries. The search for physics beyond the Standard Model may require a complementary approach, such as the search for non-renormalizable interactions via the Standard Model Effective Field Theory.
