description: A method for reconstructing the energy landscape of simple polypeptidic chains is described. We show that we can construct an equivalent representation of the energy landscape by a suitable directed graph. Its topological and dynamical features are shown to yield an effective estimate of the time scales associated with the folding and with the equilibration processes. This conclusion is drawn by comparing molecular dynamics simulations at constant temperature with the dynamics on the graph, defined by a temperature dependent Markov process. The main advantage of the graph representation is that its dynamics can be naturally renormalized by collecting nodes into "hubs", while redefining their connectivity. We show that both topological and dynamical properties are preserved by the renormalization procedure. Moreover, we obtain clear indications that the heteropolymers exhibit common topological properties, at variance with the homopolymer, whose peculiar graph structure stems from its spatial homogeneity. In order to obtain a clear distinction between a "fast folder" and a "slow folder" in the heteropolymers one has to look at kinetic features of the directed graph. We find that the average time needed to the fast folder for reaching its native configuration is two orders of magnitude smaller than its equilibration time, while for the bad folder these time scales are comparable. Accordingly, we can conclude that the strategy described in this paper can be successfully applied also to more realistic models, by studying their renormalized dynamics on the directed graph, rather than performing lengthy molecular dynamics simulations.

description: The aim of this paper is to investigate the separability of a spin-1/2 spinor field in a five-dimensional rotating, charged black hole constructed by Cvetic and Youm in string theory, in the case when three U(1) charges are set equal. This black hole solution represents a natural generalization of the famous four-dimensional Kerr-Newman solution to five dimensions with the inclusion of a Chern-Simons term to the Maxwell equation. It is shown that the usual Dirac equation can not be separated by variables in this general spacetime with two independent angular momenta. However if one supplements an additional counterterm into the usual Dirac operator, then the modified Dirac equation for the spin-1/2 spinor particles is separable in this rotating, charged Einstein-Maxwell-Chern-Simons black hole background geometry. A first-order symmetry operator that commutes with the modified Dirac operator has exactly the same form as that previously found in the uncharged Myers-Perry black hole case. It is expressed in terms of a rank-three totally antisymmetric tensor and its covariant derivative. This tensor obeys a generalized Killing-Yano equation and its square is a second-order symmetric Stackel-Killing tensor admitted by the five-dimensional rotating, charged black hole spacetime.

description: We present detailed heat capacity measurements for Ba(Fe(1-x)Cox)2As2 and Ba(Fe(1-x)Nix)2As2 single crystals in the vicinity of the superconducting transitions. The specific heat jump at the superconducting transition temperature (Tc), Delta Cp/Tc, changes by a factor ~ 10 across these series. The Delta Cp/T$ vs. Tc data of this work (together with the literature data for Ba(Fe0.939Co0.061)2As2, (Ba0.55K0.45)Fe2As2, and (Ba0.6K0.4)Fe2As2) scale well to a single log-log plot over two orders of magnitude in Delta Cp/Tc and over about an order of magnitude in Tc, giving Delta Cp/Tc ~ Tc^2.
Tenant Screening Algorithms: Policy Intervention

description: Tenant screening algorithms are a form of technology intended to provide quick and reliable background checks of potential tenants for landlords and management companies. In most landlord guides, the use of the tenant screening algorithms is deemed an essential part of the approval process and has become widespread in the rental industry.1 However, because of a high stakes rental market, the use of these tools may further restrict access for populations who already face housing challenges related to affordability and limited supply.2 In order to provide a more equitable housing application process, this memo finds that the unreliability of tenant screening algorithms warrants a change in policy toward restricting information included in screening reports.

description: Spielfilme sind im DaF-Unterricht, wie auch im muttersprachlichen Deutschunterricht, ein beliebtes Medium der Auseinandersetzung mit der DDR. Doch während dies bis vor fünfzehn Jahren vor allem anhand von Filmen aus der DDR erfolgte, sind nun zumeist in der Nachwendezeit entstandene Filme über die DDR das Medium der Wahl. Die Gründe für diesen Umstieg sind noch nicht erforscht, doch liegt die Vermutung nahe, dass er sich eher dem Bestreben, „etwas Aktuelles“ zu zeigen, verdankt, als reflektierten Entscheidungen, die die Potenziale und Schwierigkeiten für interkulturelles Lernen an den jeweiligen Gegenständen abwägen. Die folgenden Überlegungen zur Rolle kultureller Modelle für verschiedene Verstehensleistungen sollen eine reflektierte Filmauswahl im interkulturellen Fremdsprachenunterricht erleichtern.
Normative data study on vestibular evoked myogenic potential
Creators: name: Truong, Tin Duc
Publisher: name: Maryland Shared Open Access Repository
Year: 2015

description: Vestibular evoked myogenic potential is a specialized test within the vestibular test battery that specifically examines the integrity of the otolithic organs within the inner ear. The way in which the test is executed varies between individual clinics. Therefore, it is important for each individual clinic to establish its own set of normative data that are unique to their chosen recording and stimulus parameters. The goal of this current study is to establish normative data for cervical and ocular vestibular myogenic evoked potential tests at the Towson University Hearing and Balance clinic.

D-cycloserine but not D-serine reverses memory impairments in a scopolamine induced model of Alzheimer's disease

Publisher: name: Maryland Shared Open Access Repository
Year: 2013

description: Acting as agonists on the glycine site of the NMDAR system, D-Serine (DS) and D-Cycloserine (DCS) have been described as mediators of hippocampal function and therefore of learning and memory. With degradation of the hippocampus a primary factor observed in Alzheimer?s Disease (AD), the present study sought to investigate whether DS and DCS could offer some cognitive benefit to patients with AD. This theory was tested using the Scopolamine (SCOP) model of AD in rats. The Competitive Place Task (CPT) water maze was used to investigate the influence of DS and DCS on learning and memory in both SCOP treated and normal rats. The CPT also allowed for exploration into the nature of the striatum and hippocampus as competing memory systems and the degree to which each of these drugs is influencing them. Results indicated that DCS but not DS was able to reverse the working and spatial memory impairment caused by SCOP. DCS was unable improve long term recall in SCOP animals and DS and DCS alone showed no cognitive benefit in normal subjects. The present study found evidence to suggest that DS may primarily be influencing the striatal but not hippocampal, a theory that is in debate.

description: Mindfulness Based-Cognitive Therapy (MBCT) was designed to prevent relapse of depression although its uses have recently expanded. The current meta-analysis examines the effect sizes for eight studies of MBCT for treatment of depression (N = 350). The average intervention effect size (M* = 1.02, SEM* = 0.14) was significantly larger than the average control effect size (M* = 0.37, SEM* = 0.15; ZDiff = 3.19, p < .01). These results indicate that MBCT is an effective treatment for reducing the severity of active depression in both the standard and shorted version of the treatment. Specific comparisons to control groups are discussed. Overall, MBCT appears to be a viable alternative treatment for active depression.

description: Language instructors are bombarded in professional conversations, conferences and publications with glowing reports and demonstrations of "leading edge", "new generation", "must-have" second or foreign language software packages. Indeed, with the advent of such interesting and attractive software as A la rencontre de Philippe or Dans un quartier de Paris for French, Berliner Sehen or Pilot for German, or Ucuchi for Quechua, and their ilk, it comes as little surprise that a great deal of discussion, often of a highly technical sort, surrounds these new tools for teaching and learning. A question that many of us in the profession are sometimes reluctant to ask about newer software packages is whether in fact the software has convincingly been shown to fulfill its educational purposes. What do we know about the educational effectiveness of the current generation of multimedia language learning software? And, underlying that question, how best do we go about finding out? The present paper makes a modest claim. The authors - all working as language instructors/researchers in school and university settings and sometime designer-developers of language software - argue that a new approach is needed to the educational evaluation of language learning software that falls under the rubric "new media" or "multimedia" as distinct from previous generations of CALL software. The paper discusses the case for such a new approach by arguing that present approaches to the evaluation of CALL software, while reasonably adequate (although not wholly, we note) for earlier generations of CALL programs, are not appropriate for what we show to be a new genre of CALL software distinguished by its shared assumptions about language learning and teaching as well as by its technical design. We conclude by sketching a research-based program of what we term "E/Valuation" that aims to assist language educators to answer questions about the educational effectiveness of recent multimedia language learning software. We suggest that this needs to take into account not only the nature of the new media and its potential to promote language learning in novel ways, but also current professional knowledge about language learning and teaching.

description: Approximately 95% of global steel production relies on continuous casting, there is a need for a practical, cost-effective, and accurate method to guide real-world production. A successful integration of three individual CFD models – spray cooling model, solidification model, and carbon segregation model – was accomplished. To understand the heat transfer behavior on a heated surface, a three-dimensional model was used to simulate the interaction of liquid droplets with a heated surface during the secondary cooling process, employing air-mist nozzles. The real nozzle layout, as employed in a full-scale continuous caster to provide HTC data on slab surface. For solidification model, enthalpy-porosity methods were applied to estimate the metallurgical length and surface temperatures. Carbon transport within the continuous caster was considered, revealing a phenomenon of positive segregation at the center of the slab. Building upon this foundation, further investigations were carried out to assess the implications of nozzle clogging. These effects encompass surface temperature, metallurgical length, and carbon concentration. Commercial software ANSYS Fluent 2021 R2 and Simcenter STAR-CCM+ 2302 are chosen for their exceptional computational performance. MATLAB and Python play key roles in both pre and post processing, including mapping HTC profiles, visualizing shell growth, and extracting temperature and cooling profiles.
Community strengths to career capacities: family support, authenticity and career decision-making self-efficacy in the lesbian, gay and bisexual community
Creators: name: Russon, Jody
Publisher: name: Maryland Shared Open Access Repository
Year: 2011

description: Theories in career development and positive psychology have discussed the importance of career decision-making self-efficacy (CDMSE) for diverse groups; however, there has been little development in this area for the lesbian, gay and bisexual (LGB) community (Lent, Brown & Hackett, 1994; Perez, 2007; Taylor & Betz, 1983). Previous research has shown that LGB individuals may experience a disruption in career development as psychological energy could be focused on developing sexual identity (Hetherington, 1991). The present study sought to determine if strength-based characteristics, found among LGB individuals, such as authenticity, acceptance from others, and social support from friends and family, predicted CDMSE (Kernis & Goldman, 2006; Mohr & Fassinger, 2003; Procidano & Heller). Survey results from 55 LGB-identified individuals indicated that social support from family and need for acceptance accounted for a significant amount of the variance in CDMSE. Implications for research and career counseling are discussed.

Predicting the effects of land cover and stormwater management on stream health in Baltimore County, Maryland
Creators: name: Hirsch, Robert H.
Publisher: name: Maryland Shared Open Access Repository
Year: 2011

description: Maintaining stream health in urban and agricultural riverscapes is a challenge for environmental managers, and requires a better understanding of stream ecology and biogeography. This study develops a spatial generalized least squares model for predicting the effects of land cover and stormwater management (SWM) on Piedmont stream health in Baltimore County, Maryland. Such models are needed to better integrate stream health management with local land use planning and SWM programs. The model predicts stream health impairment with >80% accuracy. Model performance is suitable for supporting a precautionary policy for preventing water quality impairment. Results show how SWM reshapes catchments, and interacts with stream health through coupled human-environment systems. Riparian buffers had little impact on stream health, while large effects were found for impervious surfaces and forest cover. Continuing development of SWM data resources and refinements to the model promise new knowledge and more nuanced and precise predictions.

description: This study focused on the relationship between health risk behaviors and racial and gender discrimination, of interest was the relationship between the risk and benefit evaluation of engaging in health risk behaviors and discrimination. Findings indicated that Black (African American, African, and Caribbean) females engaged in fewer risk behaviors than European American females. In addition, Black females reported more racial discrimination than European American females. However, there were no significant differences in gender discrimination. There was no support of a relationship between risk and benefit evaluation and race or discrimination. Sensation seeking was supported as the most pertinent factor in exploring risk behaviors.

description: Let Λbe a finite subset of Z^d. We study the following sandpile model on Λ. The height at any given vertex x of Λis a positive real number, and additions are uniformly distributed on some interval [a,b], which is a subset of [0,1]. The threshold value is 1; when the height at a given vertex exceeds 1, it topples, that is, its height is reduced by 1, and the heights of all its neighbours in Λincrease by 1/2d. We first establish that the uniform measure μon the so called "allowed configurations" is invariant under the dynamics. When a < b, we show with coupling ideas that starting from any initial configuration of heights, the process converges in distribution to μ, which therefore is the unique invariant measure for the process. When a = b, that is, when the addition amount is non-random, and a is rational, it is still the case that μis the unique invariant probability measure, but in this case we use random ergodic theory to prove this; this proof proceeds in a very different way. Indeed, the coupling approach cannot work in this case since we also show the somewhat surprising fact that when a = b is rational, the process does not converge in distribution at all starting from any initial configuration.

description: To evaluate site quality and to develop multi-conjugative adaptive optics systems for future large solar telescopes, characterization of contributions to seeing from heights up to at least 12 km above the telescope is needed. We describe a method for evaluating contributions to seeing from different layers along the line-of-sight to the Sun. The method is based on Shack Hartmann wavefront sensor data recorded over a large field-of-view with solar granulation and uses only measurements of differential image displacements from individual exposures, such that the measurements are not degraded by residual tip-tilt errors. We conclude that the proposed method allows good measurements when Fried's parameter r_0 is larger than about 7.5 cm for the ground layer and that these measurements should provide valuable information for site selection and multi-conjugate development for the future European Solar Telescope. A major limitation is the large field of view presently used for wavefront sensing, leading to uncomfortably large uncertainties in r_0 at 30 km distance.

Year: 2011

description: A Spanish-Language Modified Rhyme Test (MRT) for word recognition testing was developed using the original MRT structure by House et al. (1965) with modifications as specified by Aguilar (1991). The greatest modification to the Spanish-Language MRT originally proposed by Aguilar (1991) is the use of bisyllabic Spanish words instead of monosyllabic words. A total of six 50-word lists were developed and recorded onto a compact disk (CD). This study also included testing of the developed test material in order to collect normative data. Forty four (N=44) native Spanish-speaking participants (18 males, 26 females) with normal hearing were included in this study. Paired-samples t-tests showed no ear, age or gender effect between the mean scores. Individuals with normal hearing scored close to or equal to 100% correct on all lists. Further studies, which may include a larger sample size and the inclusion of Spanish-speaking participants with hearing loss, are necessary in order to further validate the materials.

We identify systematically the universal quantities in the beta function equations, and we give explicit formulae for the universal coefficients at next-to-leading order in terms of integrated correlation functions. As an example, we analyse the radius-dependence of the conformal dimension of some boundary operators for the case of a single Neumann brane on a circle, and for an intersecting brane configuration on a torus, reproducing in both cases the expected geometrical answer.

description: We present a geometric study of the radio and gamma-ray pulsar B1055-52 based on recent observations at the Parkes radio telescope. We conclude that the pulsar's magnetic axis is inclined at an angle of 75 degrees to its rotation axis and that both its radio main pulse and interpulse are emitted at the same height above their respective poles. This height is unlikely to be higher or much lower than 700 km, a typical value for radio pulsars. It is argued that the radio interpulse arises from emission formed on open fieldlines close to the magnetic axis which do not pass through the magnetosphere's null (zero-charge) surface. However the main pulse emission must originate from fieldlines lying well outside the polar cap boundary beyond the null surface, and farther away from the magnetic axis than those of the outergap region where the single gamma-ray peak is generated. This casts doubt on the common assumption that all pulsars have closed, quiescent, corotating regions stretching to the light cylinder.

Corrosion behaviour of nickel and monel in aqueous fluoride media.
Creators: name: Ney, Hugh Daniel Wallingford
Publisher: name: University of British Columbia
Year: 2011

description: The corrosion behaviour of nickel and monel in aqueous fluoride solutions was studied by potentiostatic polarization techniques and surface examination of the corroded specimens. Nickel does not exhibit the usual active-passive transition for 0 < pH < 4.0 but corrodes rapidly especially at the grain boundaries. In the range 4.0 < pH < 6.5 the nickel-polarization curve contains two active regions. Nickel is passive in contact with a fluoride solution with 6.5 < pH < 12.0. Polarization curves of nickel in fluoride solutions of varied pH's and fluoride ion concentrations in the range 4.0 < pH < 7.0 revealed that the current as a function of potential in the first active region is independent of fluoride ion concentration but dependent on pH. The currents in the first passive and second active regions are a function of pH and fluoride ion concentration. Surface examinations showed that nickel corrodes at the grain boundaries in the second active region. A mechanism has been proposed which accounts for corrosion in the second active region by F⁻ adsorption and passivation by either H₂O or OH⁻ adsorption on the anodically polarized metal surface. A mathematical analysis based on competitive adsorption of these species as a function of electrode potential is shown to be consistent with the experimental data. Monel corrodes at less than half the rate of nickel at the mixed potential in fluoride solutions with 0< pH < 6.5 due to its larger hydrogen overvoltage. Monel exhibits active-passive behaviour similar to nickel but with the passive current up to 6 times as large.

description: Als die Brüder Skladanowsky in Berlin und die Brüder Lumière in Paris 1895 erstmals Filmprojektionen an die Öffentlichkeit brachten, ahnten sie noch nicht, dass das neue Medium die Kunstform des 20. Jahrhunderts schlechthin werden würde. Auch Georges Méliès, der 1902 mit Le Voyage dans la Lune den ersten Science-Fiction-Film schuf, betrachtete den Film zunächst vor allem als kreative Möglichkeit, Zauberkunst und Schauspiel in einem Medium miteinander zu verbinden. Skladanowsky, Lumière und Méliès prägten Stile und Strukturen, von denen in der Folge Filmgenres und Subgenres (Dokumentation, Drama, Animation, Abenteuerfilm, Spielfilm u.a.) abgeleitet wurden. Heute gilt der Film als Konvergenzmedium, das ältere und neuere Medien, filmspezifische und nicht filmspezifische Kodes (vgl. Metz 1972) in sich vereint und eine der prägnantesten und anpassungsfähigsten Erscheinungen der medialen Kultur der letzten Jahrzehnte darstellt.

description: We compare [O IV] 25.89 micron emission line luminosities with very hard (10-200 keV) X-rays from Swift, Integral, and BeppoSAX for a complete sample of 89 Seyferts from the Revised Shapley-Ames sample. Using Seyfert 1s, we calibrate [O IV] as a measure of AGN intrinsic luminosity, for particular use in high-obscuration environments. With this calibration, we measure the average decrement in 14-195 keV X-ray to [O IV] luminosity ratio for Seyfert 2s compared to type 1s. We find a decrement of 3.1 +- 0.8 for Seyfert 2s, and a decrement of 5.0 +- 2.7 for known Compton-thick Seyfert 2s. These decrements imply column densities of approximately log N(H)=24.6 and 24.7 cm^-2, respectively. Thus, we infer that the average Seyfert 2 is more highly obscured and intrinsically more luminous than would be inferred even from the very hard X-rays. We demonstrate two applications of the hard X-ray to [O IV] ratio. We measure a column density for the extremely obscured NGC 1068 of log N(H)=25.3-25.4 cm^-2. Finally, by comparing [O IV] luminosities to total infrared luminosities for twelve bright ultraluminous infrared galaxies, we find that four have substantial AGN contributions.

description: Der Erwerb der deutschen Wortstellungsregeln ist eines der besonders intensiv erforschten Themen. In diesem Artikel sollen zunächst die Grenzen der in der Forschung diskutierten Erklärungsansätze (Erwerbssequenzen einerseits, Transfer andererseits) gezeigt und anschließend ein psycholinguistisches Konzept „Entstehung eines morphosyntaktischen Spannungsfelds“ zur Erklärung der mit Wortstellungen verbundenen Produktionsschwierigkeiten beim Erlernen des Deutschen vorgestellt werden. Ferner werden Zusammenhänge zwischen Morphosyntax und Prosodie sowie deren Nutzungsmöglichkeiten zur Vermittlung der als besonders schwierig geltenden Nebensatzstruktur für DaF-Lernende aufgezeigt.

description: Ist eine Sprache - neudeutsch gesprochen - sexy, wenn sie weltweit gesprochen wird? Ist eine Sprache nicht (mehr) sexy, wenn sie gegenüber einer lingua franca globalisierter Ökonomie quantitativ „an Boden verliert“? Ist es in einer so empfundenen Situation klug, wenn u.a. akademische Sprachhüter, wenngleich empirisch abgesichert, ein Wort wie Fanmeile zum Wort, wohlgemerkt nicht zum Unwort, sondern zum deutschen Wort des Jahres (2006) küren? Ein solches Vorgehen ist nicht Teil der Lösung, sondern Teil des Problems. Als Problem wird häufig der Rückgang der Bedeutung der deutschen Sprache etwa im Vergleich zur englischen Sprache weltweit ausgemacht. Was aber meint in diesem Zusammenhang Bedeutung, woran wird der Verlust an Bedeutung festgemacht?

Effect of coexisting order of various form and wave vector on low-temperature thermal conductivity in d-wave superconductors

description: In light of recent experimental evidence of density wave order in the cuprates, we consider a phenomenological model of a d-wave superconductor with coexisting charge, spin or pair density wave order of various form and wave vector. We study the evolution of the nodal structure of the quasiparticle energy spectrum as a function of the amplitude of the coexisting order and perform diagrammatic linear response calculations of the low-temperature (universal-limit) thermal conductivity. The work described herein expands upon our past studies, which focused on a particular unit-cell-doubling charge density wave, generalizing our techniques to a wider class of coexisting order. We find that the question of whether the nodes of the d-wave superconductor survive amidst a reasonable level of coexisting order is sensitive to the form and wave vector of the order. However, in cases where the nodes do become gapped, we identify a signature of the approach to this nodal transition, in the low-temperature thermal conductivity, that appears to be quite general. The amplitude of this signature is found to be disorder-dependent, which suggests a connection between the presence of coexisting order in the underdoped cuprates and recent observations of deviations from universal (disorder-independent) thermal conductivity in the underdoped regime.

description: Wörter lernen gehört im Sprachunterricht zur täglichen Arbeit von Lernenden, und Lehrerinnen und Lehrer können und müssen bei dieser Arbeit Hilfestellung leisten, indem sie Anregungen geben und Kniffe und Verfahren vermitteln, wie die Lernenden möglichst rasch und nachhaltig neue unbekannte Wörter der Zielsprache lernen und behalten können. Die vorliegende Fernstudieneinheit schließt sich an zwei Veröffentlichungen aus der Reihe der Fernstudienangebote an, in denen es um die Erarbeitung der kulturspezifischen Bedeutung von Wörtern und den Gebrauch von bestimmten lexikalischen Mitteln und Strukturen in Alltagssituationen ging. Sie will verdeutlichen, dass die Wortschatzarbeit nicht von den übrigen Lernbereichen isoliert gesehen werden kann, sondern notwendigerweise mit der Entwicklung anderer sprachlicher Fertigkeiten wie Lesen, Hörverstehen, Sprechen und Schreiben korreliert. Schließlich partizipiert der Wortschatz an sämtlichen Zielbereichen des Sprachunterrichts: den Kenntnissen, den Fertigkeiten und den Einsichten. Er ist zudem der Sektor, in dem am meisten Stoff gedächtnismäßig zu bewältigen ist. In seiner Anlage und Präsentation folgt der Beitrag Rainer Bohns der erfolgreichen und überzeugenden Tradition des Fernstudienprojekts des DIFF, der GhK und des GI unter der Leitung von Gerhard Neuner.

description: We propose a method of manipulating a quantum register remotely with the help of a single ancilla that steers the evolution of the register. The fully controlled ancilla qubit is coupled to the computational register solely via a fixed unitary two-qubit interaction, E, and then measured in suitable bases. We characterize all interactions E that induce a unitary, step-wise deterministic measurement back-action on the register sufficient to implement any arbitrary quantum channel. Our scheme offers significant experimental advantages for implementing computations, preparing states and performing generalized measurements as no direct control of the register is required.

Demystifying the coronal line region of active galactic nuclei: spatially resolved spectroscopy with HST

description: We present an analysis of STIS/HST optical spectra of a sample of ten Seyfert galaxies aimed at studying the structure and physical properties of the coronal-line region (CLR). The high-spatial resolution provided by STIS allowed us to resolve the CLR and obtain key information about the kinematics of the coronal-line gas, measure directly its spatial scale, and study the mechanisms that drive the high-ionisation lines. We find CLRs extending from just a few parsecs (~10 pc) up to 230 pc in radius, consistent with the bulk of the coronal lines (CLs) originating between the BLR and NLR, and extending into the NLR in the case of [FeVII] and [NeV] lines. The CL profiles strongly vary with the distance to the nucleus. We observed line splitting in the core of some of the galaxies. Line peak shifts, both red- and blue-shifts, typically reached 500 km/s, and even higher velocities (1000 km/s) in some of the galaxies. In general, CLs follow the same pattern of rotation curves as low-ionisation lines like [OIII]. From a direct comparison between the radio and the CL emission we find that neither the strength nor the kinematics of the CLs scale in any obvious and strong way with the radio jets. Moreover, the similarity of the flux distributions and kinematics of the CLs and low-ionisation lines, the low temperatures derived for the gas, and the success of photoionisation models to reproduce, within a factor of few, the observed line ratios, point towards photoionisation as the main driving mechanism of CLs.

description: We investigate ballistic transport and quantum interference in a nanoscale quantum wire loop fab-ricated as a GaAs/AlGaAs field-effect heterostructure. Four-terminal measurements of current and voltage characteristics as a function of top gate voltages show negative bend resistance as a clear signature of ballistic transport. In perpendicular magnetic fields phase-coherent transport leads to Aharonov-Bohm (AB) conductance oscillations which show equal amplitudes in the local and the non-local measurement at a temperature of 1.5 K and above. We attribute this novel observation to the symmetry of the orthogonal cross junctions connecting the four quantum wire leads with the asymmetric quantum wire ring.
