Integral Field Spectroscopy of the Extended Emission-Line Region of 4C 37.43

description: We present Gemini integral field spectroscopy and Keck II longslit spectroscopy of the extended emission-line region (EELR) around the quasar 4C 37.43. The velocity structure of the ionized gas is complex and cannot be explained globally by a simple dynamical model. The spectra from the clouds are inconsistent with shock or ``shock + precursor'' ionization models, but they are consistent with photoionization by the quasar nucleus. The best-fit photoionization model requires a low-metallicity (12+log(O/H) < 8.7) two-phase medium, consisting of a matter-bounded diffuse component with a unity filling-factor (N ~ 1 \cc, T ~ 15000 K), in which are embedded small, dense clouds (N ~ 400 \cc, T ~ 10^4 K). The high-density clouds are transient and can be re-generated through compressing the diffuse medium by low-speed shocks (V_S \lesssim 100 \kms). Our photoionization model gives a total mass for the ionized gas of about 3x10^{10} M_sun, and the total kinetic energy implied by this mass and the observed velocity field is ~2x10^{58} ergs. The fact that luminous EELRs are confined to steep-spectrum radio-loud quasars, yet show no morphological correspondence to the radio jets, suggests that the driving force producing the 4C 37.43 EELR was a roughly spherical blast wave initiated by the production of the jet. That such a mechanism seems capable of ejecting a mass comparable to that of the total interstellar medium of the Milky Way suggests that ``quasar-mode'' feedback may indeed be an efficient means of regulating star formation in the early universe.

description: In this paper we consider the use of certain classical analogues to quantum tunneling behavior to improve the performance of simulated annealing on a discrete spin system of the general Ising form. Specifically, we consider the use of multiple simultaneous spin flips at each annealing step as an analogue to quantum spin coherence as well as modifications of the Boltzmann acceptance probability to mimic quantum tunneling. We find that the use of multiple spin flips can indeed be advantageous under certain annealing schedules, but only for long anneal times.

description: В связи с переходом экономики Российской Федерации от директивных методов управления к рыночным механизмам регулирования, принципиально иными стали роль, место и функции институтов государственного финансового контроля в системе государственного управления. В широком смысле они призваны, наряду с непосредственно контрольными функциями, выполнять функции инструмента государственного регулирования и стабилизации экономических процессов. В условиях рыночного регулирования экономики институты государственного финансового контроля стали выполнять и относительно новую для них фискальную функцию. Главное внимание в статье обращается на то, что при реализации своих функций система государственного финансового контроля опирается на один из своих мобильных, оперативных, и от этого наиболее эффективных, инструментов — на контрольно-ревизионные институты и их основные организационные функции. Исследование показало, что непосредственная взаимосвязь контрольно-ревизионных институтов с объектами и субъектами экономических отношений позволяет достичь высокого уровня объективности результатов финансового контроля и как следствие — выработки своевременных и правильных решений и мер регулирования экономической и финансовой политики государства.
Critical mass of bacterial populations in a generalized Keller-Segel model. Analogy with the Chandrasekhar limiting mass of white dwarf stars

description: We point out a remarkable analogy between the limiting mass of white dwarf stars (Chandrasekhar's limit) and the critical mass of bacterial populations in a generalized Keller-Segel model of chemotaxis [Chavanis & Sire, PRE, 69, 016116 (2004)]. This model is based on generalized stochastic processes leading to the Tsallis statistics. The equilibrium states correspond to polytropic configurations similar to gaseous polytropes in astrophysics. For the critical index n_3=d/(d-2) (where d is the dimension of space), the theory of polytropes leads to a unique value of the mass M_c that we interpret as a limiting mass. In d=3, we find M_c=202.8956... and in d=2, we recover the well-known result M_c=8 pi (in suitable units). For MM_c, the system collapses and forms a Dirac peak containing a mass M_c surrounded by a halo. This paper exposes the model and shows, by simple considerations, the origin of the critical mass. A detailed description of the critical dynamics of the generalized Keller-Segel model will be given in a forthcoming paper.

description: The dental follicle is part of the tooth germ, and isolated stem cells from this tissue (dental follicle cells; DFCs) are considered, for example, for regenerative medicine and immunotherapies. However somatic stem cells can also improve pharmaceutical research. Cell proliferation is limited by the induction of senescence, which, while reducing the therapeutic potential of DFCs for cell therapy, can also be used to study aging processes at the cellular level that can be used to test anti-aging pharmaceuticals. Unfortunately, very little is known about cellular senescence in DFCs. This review presents current knowledge about cellular senescence in DFCs.
A local hidden-variable model for experimental tests of the GHZ puzzle
Creators: name: La Cour, Brian R.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The Greenberger-Horne-Zeilinger (GHZ) puzzle has been used to study quantum nonlocality and provide an all-or-nothing, no-go theorem for local hidden-variable models. Recent experiments using coincident-detected entangled photons prepared in a three-particle GHZ state have been used to test quantum nonlocality, but fail to rule out local realism due to a reliance on the fair-sampling hypothesis and insufficient detection efficiency. This paper describes a physically motivated local hidden-variable model based on amplitude-threshold detection that is capable of producing similar results. Detection efficiencies for the model are within the bounds permitted for local realism and, interestingly, exhibit statistical correlations between detectors, even when the detection events are spacelike separated. Increasing the detection threshold improves agreement with the ideal quantum predictions at the cost of decreased detection efficiency. A curious emergent feature of the model is that detection efficiencies may depend upon which observables are chosen for measurement.

description: Orienting objects is a critical component in the automation of many packing and assembly tasks. We present an algorithm to orient novel objects given a depth image of the object in its current and desired orientation. We formulate a self-supervised objective for this problem and train a deep neural network to estimate the 3D rotation as parameterized by a quaternion, between these current and desired depth images. We then use the trained network in a proportional controller to re-orient objects based on the estimated rotation between the two depth images. Results suggest that in simulation we can rotate unseen objects with unknown geometries by up to 30° with a median angle error of 1.47° over 100 random initial/desired orientations each for 22 novel objects. Experiments on physical objects suggest that the controller can achieve a median angle error of 4.2° over 10 random initial/desired orientations each for 5 objects.

description: We study the emergence of de Sitter space in Euclidean dynamical triangulations (EDT). Working within the semi-classical approximation, it is possible to relate the lattice parameters entering the simulations to the partition function of Euclidean quantum gravity. We verify that the EDT geometries behave semi-classically, and by making contact with the Hawking-Moss instanton solution for the Euclidean partition function, we show how to extract a value of the renormalized Newton's constant from the simulations. This value is consistent with that of our previous determination coming from the interaction of scalar particles. That the same universal constant appears in these two different sectors of the theory is a strong indication that EDT provides a viable formulation of quantum gravity.

A follow-up evaluation of business education career preparation programs in Vancouver secondary schools
Creators: name: Good, Dianne E.
Publisher: name: University of British Columbia
Year: 2010

description: Career Preparation programs have been offered in British Columbia since 1980. However, in that time very little formal evaluation has been conducted to determine if Career Preparation programs are achieving the stated objectives. This study, based on Business Education Career Preparation programs in Vancouver secondary schools, surveyed Career Preparation students one, two, and three years after graduation. Schools which had started Business Education Career Preparation programs in September 1982 or earlier were selected. Graduates of these schools who completed a Business Education Career Preparation program in 1984, 1985, or 1986, were surveyed to determine their employment and post-secondary education experiences, whether their post-secondary education or employment was related to their Career Preparation specialties, and their perceptions of the program. The purpose of the study was to determine the strengths and weaknesses of the Business Education Career Preparation programs offered in Vancouver Secondary Schools in order to make recommendations for program improvements. The results show that 94% of respondents held at least one job since graduating from secondary school; 77% of respondents continue their education at a post-secondary institution; 67% of post-secondary programs enrolled in by respondents were at least somewhat related to their Career Preparation specialty; and 67% of jobs held since graduating from secondary school were at least somewhat related to their Career Preparation specialty. The Career Preparation program was rated at least somewhat helpful in facilitating progress in post-secondary education by 81% of respondents; 93% of respondents rated Career Preparation at least somewhat helpful in making career choices; 91% rated it at least somewhat helpful in providing employable skills; 85% rated it at least somewhat helpful in providing job search skills; and 68% rated it at least somewhat helpful in providing employment contacts. Overall, the Business Education Career Preparation program offered in Vancouver was judged as meeting the program objectives of the provincial curriculum. Recommendations are made for the program, including: matching students more carefully to work experience placements which meet their interests, career goals and specialty; more careful monitoring of work experience sites to ensure that appropriate tasks are being assigned; offering programs which will interest both males and females; coordinating employment opportunities for graduates; improving articulation with post-secondary programs; and structuring Career Preparation programs to allow for flexibility in course requirements and work experience.
title: Urban Social Aesthetics: Individuating Contemporary Art's Urban Marxist Tendency
Creators: name: Melia, A
Publisher: name: Liverpool John Moores University
Year: 2021

description: This thesis examines what I call ‘urban social aesthetics’, which, I contend, is an ‘urban Marxist’ tendency in contemporary art, characterised by 1:1 scale engagement with the social urgencies of urban sites as a means for anti-capitalist agency and resistance. It is my contention that, within contemporary art scholarship, instances of this urban Marxist tendency are often not individuated from the mass of other existing urban art productions. Despite engaging with the most pressing urgencies of our contemporary moment (i.e. housing, gentrification, homelessness and contemporary forms of racial segregation), there is arguably a lack of debate that singles out and underscores this urban Marxist tendency. How can art theoreticians and scholars pinpoint this urban Marxist category of contemporary practice? How can such intellectual actors individuate this practice from the multitude of other urban art productions and approaches so that it may acquire critical, discursive independence? In this thesis, I suggest that the discourses and practices of ‘Situationism’ and ‘experimental institutionalism’ could contribute to this task. This thesis’ overarching aim is to contend that the urban-centric debates and praxis of the Situationist International and experimental institutionalism could contribute to the examination of contemporary art’s urban Marxist tendency (‘urban social aesthetics’). The Situationist International was a predominantly European art collective that sought to resist capitalism and transform urban experience. On the other hand, experimental institutionalism is a field of curatorial practice, institutional reform and debate concerned with the art institution’s potential transformation into a socially responsible agent. I argue in this thesis that said field’s socially responsive approach to instituting and curating tends to engage with decidedly urban conditions. Conferring with the major hub for experimental institutionalism that is the L’Internationale museum confederation (as well as its collaborators and partners), this thesis asks—is it the urban post-Marxist theory of the Situationists that could lend to an examination of urban social aesthetics or the ongoing debates/praxis of experimental institutionality?

description: We use a 1030 nm laser with 7 ps pulse duration and average power up to 100 W to ablate pyramid-shape subwavelength structures (SWS) on alumina and sapphire. The SWS give an effective and cryogenically robust anti-reflection coating in the millimeter-wave band. We demonstrate average ablation rate of up to 34 mm$^3$/min and 20 mm$^3$/min for structure heights of 900 $μ$m and 750 $μ$m on alumina and sapphire, respectively. These rates are a factor of 34 and 9 higher than reported previously on similar structures. We propose a model that relates structure height to cumulative laser fluence. The model depends on the absorption length $δ$, which is assumed to depend on peak fluence, and on the threshold fluence $ϕ_{th}$. Using a best-fit procedure we find an average $δ= 630$ nm and 650 nm, and $ϕ_{th} = 2.0^{+0.5}_{-0.5}$ J/cm$^2$ and $2.3^{+0.1}_{-0.1}$ J/cm$^2$ for alumina and sapphire, respectively, for peak fluence values between 30 and 70 J/cm$^{2}$. With the best fit values, the model and data values for cumulative fluence agree to within 10%. Given inputs for $δ$ and $ϕ_{th}$ the model is used to predict average ablation rates as a function of SWS height and average laser power.

description: The low temperature acoustic properties of bulk metallic glasses measured over a broad range of frequencies rigorously test the predictions of the standard tunneling model. The strength of these experiments and their analyses is mainly based on the interaction of the tunneling states with conduction electrons or quasiparticles in the superconducting state. A new series of experiments at kHz and GHz frequencies on the same sample material essentially confirms previous measurements and their discrepancies with theoretical predictions. These discrepancies can be lifted by considering more correctly the line widths of the dominating two-level atomic-tunneling systems. In fact, dephasing caused or mediated by interaction with conduction electrons may lead to particularly large line widths and destroy the tunneling sytems' two-level character in the normal conducting state.

description: Because the three-leg ladder behaves like a renormalized single Heisenberg chain we argue that a spin-Peierls instability must occur in this system when it is coupled to three-dimensional phonons. Using the bond-mean-field theory, we show that this is indeed the case. The dimerized state below the spin-Peierls transition temperature forms into the columnar dimerized phase not the staggered one. This contrasts with the argument based on antiferromagnetism. A physical argument based rather on spin bonding into singlets explains why the columnar configuration is favored. No quantum criticality (gaplessness) can occur in the columnar arrangement of the dimerized chains.

description: In event-based sensing, many sensors independently and asynchronously emit events when there is a change in their input. Event-based sensing can present significant improvements in power efficiency when compared to traditional sampling, because (1) the output is a stream of events where the important information lies in the timing of the events, and (2) the sensor can easily be controlled to output information only when interesting activity occurs at the input. Moreover, event-based sampling can often provide better resolution than standard uniform sampling. Not only does this occur because individual event-based sensors have higher temporal resolution, it also occurs because the asynchrony of events allows for less redundant and more informative encoding. We would like to explain how such curious results come about. To do so, we use ideal time encoding machines as a proxy for event-based sensors. We explore time encoding of signals with low rank structure, and apply the resulting theory to video. We then see how the asynchronous firing times of the time encoding machines allow for better reconstruction than in the standard sampling case, if we have a high spatial density of time encoding machines that fire less frequently.

description: Angle resolved photoemission on underdoped Bi2Sr2CaCu2O8 reveals that the magnitude and d-wave anisotropy of the superconducting state energy gap are independent of temperature all the way up to Tc. This lack of T variation of the entire k-dependent gap is in marked contrast to mean field theory. At Tc the point nodes of the d-wave gap abruptly expand into finite length ``Fermi arcs''. This change occurs within the width of the resistive transition, and thus the Fermi arcs are not simply thermally broadened nodes but rather a unique signature of the pseudogap phase.

description: Conformal rescaling of conformal Yano--Killing tensors and relations between Yano and CYK tensors are discussed. Pullback of these objects to a submanifold is used to construct all solutions of a CYK equation in anti-de Sitter and de Sitter spacetimes. Properties of asymptotic conformal Yano--Killing tensors are examined for asymptotic anti-de Sitter spacetimes. Explicit asymptotic forms of them are derived. The results are used to construct asymptotic charges in asymptotic AdS spacetime. Well known examples like Schwarzschild-AdS, Kerr-AdS and NUT-AdS are examined carefully in the construction of the concept of energy, angular momentum and dual mass in asymptotic AdS spacetime.

description: The Navier--Stokes equations arise naturally as a result of Ehrenfests' coarse-graining in phase space after a period of free-flight dynamics. This point of view allows for a very flexible approach to the simulation of fluid flow for high-Reynolds number. We construct regularisers for lattice Boltzmann computational models. These regularisers are based on Ehrenfests' coarse-graining idea and could be applied to schemes with either entropic or non-entropic quasiequilibria. We give a numerical scheme which gives good results for the standard test cases of the shock tube and the flow past a square cylinder.

description: L’objectif de ce stage M2 est de caractériser l’état et la dynamique des populations de corail rouge (Corallium rubrum) dans le Parc nationale des Calanques en 2018. Cette caractérisation des populations de corail rouge se fait via l’analyse de données biométriques issues des techniques de photogrammétrie : les images prises in situ par un plongeur ou un ROV (Remote Operated Vehicle) permettent de mesurer ex situ sur ordinateur un certain nombre de métriques caractérisant les colonies (hauteur, diamètre à la base, nombre de ramifications, densité). Ainsi il s’agit d’étudier les paramètres décrivant cinq populations situées à l’intérieur et cinq hors « zone de non- prélèvement » (ZNP, c'est-à-dire des zones de réglementations renforcées au sein du coeur marin du Parc).

description: Recently, observations of compact stars have provided new data of high accuracy which put strong constraints on the high-density behaviour of the equation of state of strongly interacting matter otherwise not accessible in terrestrial laboratories. The evidence for neutron stars with high mass (M =2.1 +/- 0.2 M_sun for PSR J0751+1807) and large radii (R > 12 km for RX J1856-3754) rules out soft equations of state and has provoked a debate whether the occurence of quark matter in compact stars can be excluded as well. In this contribution it is shown that modern quantum field theoretical approaches to quark matter including color superconductivity and a vector meanfield allow a microscopic description of hybrid stars which fulfill the new, strong constraints. The deconfinement transition in the resulting stiff hybrid equation of state is weakly first order so that signals of it have to be expected due to specific changes in transport properties governing the rotational and cooling evolution caused by the color superconductivity of quark matter. A similar conclusion holds for the investigation of quark deconfinement in future generations of nucleus-nucleus collision experiments at low temperatures and high baryon densities such as CBM @ FAIR.

description: Τα δίκτυα κινητών επικοινωνιών αποτελούν ίσως τον πλέον ραγδαία εξελισσόμενο κλάδο επικοινωνιών στις ημέρες μας. Η διασφάλιση της ορθής λειτουργίας του δικτύου και η επίτευξη υψηλών επιδόσεων προϋποθέτει την επιτήρησή του μέσω μετρήσεων. Οι μετρήσεις στα δίκτυα κινητών επικοινωνιών προϋποθέτουν τη χρήση εξειδικευμένου βιομηχανικού εξοπλισμού. Τυπικά, οι δυνατότητες αυτού του τύπου του εξοπλισμού είναι διευρυμένες, γεγονός το οποίο αντανακλά στο πλήθος των μετρήσεων που μπορούν να καταγράψουν και κυρίως στην πολυπλοκότητα της ερμηνείας τους. Στο πλαίσιο αυτό, η παρούσα εργασία έχει ως σκοπό να διεξάγει μετρήσεις στα τρία δίκτυα παροχής κινητών επικοινωνιών της Ελλάδας, ώστε να διερευνήσει: α) τις δυνατότητες ως προς τη διεξαγωγή μετρήσεων σε δίκτυα 2G GSM-3G WCDMA UMTS, β) τις ερμηνευτικές δυνατότητες ως προς τα αποτελέσματα των μετρήσεων, γ) τις δυνατότητες βελτιστοποίησης της λειτουργίας των υπό μέτρηση δικτύων βάσει της καταγραφής των υφιστάμενων επιδόσεων τους και τέλος δ) τις διαφορές και τις ομοιότητες ανάμεσα στα τρία δίκτυα σε ότι αφορά τη διαχείριση της λειτουργίας τους και τις επιδόσεις, τις οποίες επιτυγχάνουν.
Reissner-Nordstrom and charged gas spheres

description: The main point of this paper is a suggestion about the proper treatment of the photon gas in a theory of stellar structure and other plasmas. This problem arises in the study of polytropic gas spheres, where we have already introduced some innovations. The main idea, already advanced in the contextof neutral, homogeneous, polytropic stellar models, is to base the theory firmly on a variational principle. Another essential novelty is to let mass distribution extend to infinity, the boundary between bulk and atmosphere being defined by an abrupt change in the polytropic index, triggered by the density. The logical next step in this program is to include the effect of radiation, which is a very significant complication since a full treatment would have to include an account of ionization, thus fieldsrepresenting electrons, ions, photons, gravitons and neutral atoms as well. In way of preparation, we consider models that are charged but homogeneous, involving only gravity, electromagnetism and a single scalar field that represents both the mass and the electric charge; in short, anon-neutral plasma. While this work only represents a stage in the development of a theory of stars, without direct application to physical systems, it does shed some light on the meaning of the Reissner-Nordstrom solution of the modified Einstein-Maxwell equations., with an application to a simple system.

description: In Deutschland begeht jede Stunde eine Person Suizid, weltweit alle 40 Sekunden, was jährlich 703.000 Suizidfälle entspricht. Dies verdeutlicht die Wichtigkeit der Suizidprävention, in welcher in der Psychiatrie tätige Pflegekräfte eine zentrale Rolle einnehmen. Sie verbringen im Vergleich zu anderen Berufsgruppen die meiste Zeit mit den Patient:innen und können so entscheidend zur Prävention beitragen. Die Arbeit untersucht die Rolle von Pflegekräften in der Suizidprävention im psychiatrischen Kontext und analysiert vorhandene Literatur, um Bedeutung und Einfluss besser zu verstehen. Dabei wird die Fragestellung beleuchtet: Welche Rolle nehmen Pflegekräfte in der Suizidprävention ein?
 
Das methodische Vorgehen umfasste die Literaturrecherche sowie das Literaturmonitoring. Die systematische Datenbankrecherche erfolgte in PubMed, LIVIVO und CINAHL. Vierzehn relevante Studien wurden anhand festgelegter Kriterien eingeschlossen.

Die Ergebnisse des Scoping Reviews wurden in zehn Kategorien zusammen-gefasst und in die Dimensionen Aufgaben und Herausforderungen unterteilt. Die Aufgaben umfassen die Suizidrisikobewertung sowie das -management, die Gewährleistung von Sicherheit, die intra- und interdisziplinäre Zusammenarbeit, die personenorientierte Kommunikation, den Aufbau therapeutischer Beziehungen und das Vermitteln von Hoffnung. Die Herausforderungen umfassen mangelndes Wissen und den Bedarf an Fortbildung, den Umgang mit eigenen Emotionen sowie organisationale Probleme. Die Untersuchung veranschaulicht, dass Pflegekräfte eine zentrale Rolle in der Suizidprävention einnehmen, insbesondere durch die Früherkennung und Intervention. Der Aufbau einer therapeutischen Beziehung sowie eine personenzentrierte Kommunikation sind dabei essenziell. Pflegekräfte stehen jedoch vor erheblichen Herausforderungen wie Zeitmangel, emotionalem Stress und fehlender Schulung, was eine umfassende Fortbildung und organisatorische Unterstützung erforderlich macht. Die Implementierung des Recovery-Konzepts und die bevorstehende S3-Leitlinie könnten die Pflegepraxis entscheidend verbessern, erfordern jedoch weitere Forschung zur Wirksamkeit spezifischer Interventionen und zur Verbesserung der Arbeitsbedingungen der Pflegekräfte.
Enhancing SPH using moving least-squares and radial basis functions

description: In this paper we consider two sources of enhancement for the meshfree Lagrangian particle method smoothed particle hydrodynamics (SPH) by improving the accuracy of the particle approximation. Namely, we will consider shape functions constructed using: moving least-squares approximation (MLS); radial basis functions (RBF). Using MLS approximation is appealing because polynomial consistency of the particle approximation can be enforced. RBFs further appeal as they allow one to dispense with the smoothing-length -- the parameter in the SPH method which governs the number of particles within the support of the shape function. Currently, only ad hoc methods for choosing the smoothing-length exist. We ensure that any enhancement retains the conservative and meshfree nature of SPH. In doing so, we derive a new set of variationally-consistent hydrodynamic equations. Finally, we demonstrate the performance of the new equations on the Sod shock tube problem.

description: Transport is called nonreciprocal when not only the sign, but also the absolute value of the current, depends on the polarity of the applied voltage. It requires simultaneously broken inversion and time-reversal symmetries, e.g., by the interplay of spin-orbit coupling and magnetic field. So far, observation of nonreciprocity was always tied to resistivity, and dissipationless nonreciprocal circuit elements were elusive. Here, we engineer fully superconducting nonreciprocal devices based on highly-transparent Josephson junctions fabricated on InAs quantum wells. We demonstrate supercurrent rectification far below the transition temperature. By measuring Josephson inductance, we can link nonreciprocal supercurrent to the asymmetry of the current-phase relation, and directly derive the supercurrent magnetochiral anisotropy coefficient for the first time. A semi-quantitative model well explains the main features of our experimental data. Nonreciprocal Josephson junctions have the potential to become for superconducting circuits what $pn$-junctions are for traditional electronics, opening the way to novel nondissipative circuit elements.
