description: We report the epitaxial thin film synthesis of SrCu$_3$O$_4$ with infinitely stacked Cu$_3$O$_4$ layers composed of edge-sharing CuO$_4$ square-planes, using molecular beam epitaxy. Experimental and theoretical characterizations showed that this material is a metastable phase that can exist by applying tensile biaxial strain from the (001)-SrTiO$_3$ substrate. SrCu$_3$O$_4$ shows an insulating electrical resistivity in accordance with the Cu$^{2+}$ valence state revealed X-ray photoelectron spectroscopy. First-principles calculations also indicated that the unoccupied $d_{3z^2-r^2}$ band becomes substantially stabilized owing to the absence of apical anions, in contrast to $A_2$Cu$_3$O$_4$Cl$_2$ ($A = $Sr, Ba) with an $A_2$Cl$_2$ block layer and therefore a trans-CuO$_4$Cl$_2$ octahedron. These results suggest that SrCu$_3$O$_4$ is a suitable parent material for electron-doped superconductivity based on the Cu$_3$O$_4$ plane.

description: Using a coupled parametric-resonator array for generating and propagating a topological soliton in its rotating-frame phase space is theoretically and numerically investigated. In an analogy with the well-known phi4 model, the existence of a soliton is topologically protected as the boundary of two different phase domains of parametric oscillation. Numerical simulation indicates that the propagation can be triggered by switching of the phase state of one specific resonator, and the effects of damping, collision, and the symmetry lifting by harmonic drive on the propagation dynamics are studied. The topological soliton can be implemented by using electromechanical resonators, which allow its propagation dynamics to be precisely electrically controlled and provide a fully controlled on-chip test bed for the study of a topological soliton.

description: In spite of its great phenomenological success, current models of scalar field-driven inflation suffer from important unresolved conceptual issues. New fundamental physics will be required to address these questions. String theory is a candidate for a unified quantum theory of all four forces of nature. As will be shown, string theory may lead to a cosmological background quite different from an inflationary cosmology, and may admit a new stringy mechanism for the origin of a roughly scale-invariant spectrum of cosmological fluctuations.

The Profile of Narcissistic Dispositions (POND): development and validation
Creators: name: Taylor, Candace Margo
Publisher: name: University of British Columbia
Year: 2009

description: Four studies were conducted with the aim of developing a measure of narcissism that, unlike previous measures, is not inherently pathological. In Study 1, the NPI—the closest approximation to such a measure—was administered to a large-scale sample. Two separate Principal Component Analyses (PCAs) failed to replicate its reported structure, and revealed further psychometric problems. Use of an alternative item format (Likert ratings) was shown to yield much higher reliabilities than the original forced-choice format. Using the Likert item-format, the Profile of Narcissistic Dispositions (POND) was developed in Study 2. The items were based on a comprehensive analysis of the literature on "normal" narcissism. Five reliable subscales emerged from an oblique factor analysis. All five loaded substantially on the first unrotated principal component. The relationship of the POND to established self-report measures was also explored. In Study 3, the POND's structure was replicated and empirical relations were expanded: In particular, the POND showed negative correlations with various self-reports of psychopathology. In Study 4, the POND was shown to predict peer ratings of narcissism. Further peer-ratings elaborated the character of normal narcissism, that is, an interpersonal style that is marked by a dominant and secure but disagreeable social presence.

description: The frequency dependence of microwave-induced resistance oscillations (MIROs) has been studied experimentally in high-mobility electron GaAs/AlGaAs structures to explore the limits at which these oscillations can be observed. It is found that in dc transport experiments at frequencies above 120 GHz, MIROs start to quench, while above 230 GHz, they completely disappear. The results will need to be understood theoretically but are qualitatively discussed within a model in which forced electronic charge oscillations (plasmons) play an intermediate role in the interaction process between the radiation and the single-particle electron excitations between Landau levels.

description: Using X-ray sources as sensitive probes of stellar dynamical interactions in globular clusters (GCs), we study the mass segregation and binary burning processes in $ω$ Cen. We show that the mass segregation of X-ray sources is quenched in $ω$ Cen, while the X-ray source abundance of $ω$ Cen is much smaller than other GCs, and the binary hardness ratio (defined as $L_{\rm X}/(L_{\rm K}f_{b})$, with $f_{b}$ the binary fraction, $L_{\rm X}$ and $L_{\rm K}$ the cumulative X-ray and K band luminosity of GCs, respectively) of $ω$ Cen is located far below the $L_{\rm X}/(L_{\rm K}f_{b})-σ_{c}$ correlation line of the dynamically normal GCs. These evidences suggest that the binary burning processes are highly suppressed in $ω$ Cen, and other "heating mechanisms", very likely a black hole subsystem (BHS), are essential in the dynamical evolution of $ω$ Cen. Through the "black hole burning" processes (i.e., dynamical hardening of the BH binaries), the BHS is dominating the energy production of $ω$ Cen, which also makes $ω$ Cen a promising factory of gravitational-wave sources in the Galaxy.

description: The symmetry algebras of certain families of quantum spin chains are considered in detail. The simplest examples possess m states per site (m\geq2), with nearest-neighbor interactions with U(m) symmetry, under which the sites transform alternately along the chain in the fundamental m and its conjugate representation \bar{m}. We find that these spin chains, even with {\em arbitrary} coefficients of these interactions, have a symmetry algebra A_m much larger than U(m), which implies that the energy eigenstates fall into sectors that for open chains (i.e., free boundary conditions) can be labeled by j=0, 1, >..., L, for the 2L-site chain, such that the degeneracies of all eigenvalues in the jth sector are generically the same and increase rapidly with j. For large j, these degeneracies are much larger than those that would be expected from the U(m) symmetry alone. The enlarged symmetry algebra A_m(2L) consists of operators that commute in this space of states with the Temperley-Lieb algebra that is generated by the set of nearest-neighbor interaction terms; A_m(2L) is not a Yangian. There are similar results for supersymmetric chains with gl(m+n|n) symmetry of nearest-neighbor interactions, and a richer representation structure for closed chains (i.e., periodic boundary conditions). The symmetries also apply to the loop models that can be obtained from the spin chains in a spacetime or transfer matrix picture. In the loop language, the symmetries arise because the loops cannot cross. We further define tensor products of representations (for the open chains) by joining chains end to end. The fusion rules for decomposing the tensor product of representations labeled j_1 and j_2 take the same form as the Clebsch-Gordan series for SU(2). This and other structures turn the symmetry algebra \cA_m into a ribbon Hopf algebra, and we show that this is ``Morita equivalent'' to the quantum group U_q(sl_2) for m=q+q^{-1}. The open-chain results are extended to the cases |m|< 2 for which the algebras are no longer semisimple; these possess continuum limits that are critical (conformal) field theories, or massive perturbations thereof. Such models, for open and closed boundary conditions, arise in connection with disordered fermions, percolation, and polymers (self-avoiding walks), and certain non-linear sigma models, all in two dimensions. A product operation is defined in a related way for the Temperley-Lieb representations also, and the fusion rules for this are related to those for A_m or U_q(sl_2) representations; this is useful for the continuum limits also, as we discuss in a companion paper.

description: Role-Based Access Control (RBAC) is a popular model which maps roles to access permissions for resources and then roles to the users to provide access control. Role-Based Encryption (RBE) is a cryptographic form of RBAC model that integrates traditional RBAC with the cryptographic encryption method, where RBAC access policies are embedded in encrypted data itself so that any user holding a qualified role can access the data by decrypting it. However, the existing RBE schemes have been focusing on the single-organization cloud storage system, where the stored data can be accessed by users of the same organization. This paper presents a novel RBE scheme with efficient user revocation for the multi-organization cloud storage system, where the data from multiple independent organizations are stored and can be accessed by the authorized users from any other organization. Additionally, an outsourced decryption mechanism is introduced which enables the users to delegate expensive cryptographic operations to the cloud, thereby reducing the overhead on the end-users. Security and performance analyses of the proposed scheme demonstrate that it is provably secure against Chosen Plaintext Attack and can be useful for practical applications due to its low computation overhead.

description: Measurements of the loss rates for strontium n$^{3}$S$_{1}$ Rydberg atoms excited in a dense BEC are presented for values of principal quantum number $n$ in the range $49\lesssim n \lesssim 150$ and local atom densities of $\sim1$ to $3\times10^{14}$cm$^{-3}$. Two main processes contribute to loss, associative ionization and state-changing. The relative importance of these two loss channels is investigated and their $n$- and density-dependences are discussed using a model in which Rydberg atom loss is presumed to involve a close collision between the Rydberg core ion and ground-state atoms. The present measurements are compared to earlier results obtained using rubidium Rydberg atoms. For both species the observed loss rates are sizable, $\sim10^{5}-10^{6}$s$^{-1}$, and limit the time scales over which measurements involving Rydberg atoms immersed in quantum degenerate gases can be conducted.

description: We study a number of realizations of axions existing in a multi-`throat' generalization of the warped throat geometry of a Randall-Sundrum slice of $AdS_5$. As argued by previous authors, the problem of generating a suitable, phenomenologically allowed Peccei-Quinn scale is simply and elegantly solved by the warping. In compactifications with two or more throats it is possible to simultaneously solve the Standard Model hierarchy problem by the Randall-Sundrum mechanism while implementing interesting warped axion models. The constructions discussed are related to holographic duals of previously studied models of composite axions arising from strongly coupled four-dimensional dynamics.

description: In this paper we investigate quintom cosmologies with arbitrary potentials from the dynamical systems perspective. The dynamical systems analysis is complete in the sense that it includes the asymptotic regime where both scalar fields diverge, which proves to be particularly relevant in connection with the existence of tracking phases. The results of the present study indicate that the existence of phantom attractors is not generic: for quintom models there may exist either de Sitter attractors associated with the saddle points of the potential, or tracking attractors in the asymptotic regime where the scalar fields diverge.

description: We estimate four-nucleon force effects between different 4He wave functions by calculating the expectation values of four-nucleon potentials which were recently derived within the framework of chiral effective field theory. We find that the four-nucleon force is attractive for the wave functions with a totally symmetric momentum part. The additional binding energy provided by the long-ranged part of the four-nucleon force is of the order of a few hundred keV.

Unheimliche Heimat: Reibungsflächen Zwischen Kultur und Nation zur Konstruktion von Heimat in Deutschsprachiger Gegenwartsliteratur
Creators: name: Strzelczyk, Florentine
Publisher: name: University of British Columbia
Year: 2009

description: The thesis explores the vexed concept of Heimat in recent German culture. Heimat evokes an exclusive group, founded on the idea of the unity and homogeneity of its members. Conflicts arise around the concept because it constructs oppositions between those who belong and those who do not, insiders and outsiders, the domestic and known in opposition to the foreign and strange. Historically, the concept has been used to tell a story about the cohesion of the German nation; it has also, however, been used to assimilate, eliminate, or exile its Others. The thesis examines how the legacies of the concept and its narrative reverberate through the nation-building process of Germany today. The concept of Heimat is active in films, literature, the law and contemporary German society. The argument is that the concept of Heimat still shapes German identity in ways that use old forms and oppositions to respond to recent social changes. It is argued further that the tensions around the concept have not diminished, but are spreading into many different areas of German everyday life. Two films by Edgar Reitz provide the starting point for exploring the tensions around Heimat in contemorary German culture. Following readings of texts by Jewish-German, Austrian- German, Swiss-German, Persian-German, Rumanian-German, East and West German authors show the concept persisting in different forms with different consequences, according to the different cultural contexts. In each of these contexts, the concept of German Heimat produces both social cohesion and social tensions. As much as people are united by the concept, they are also driven apart by its differentiating and disintegrating mechanisms. Motivated by the search for communal intimacy, the concept also has the effect of controlling and manipulating what appears different and alien. As such a network of interests and strategies it is not merely closed, fixed and bounded, as desired perhaps by the dominant cultural groups, but rather open for contestation and negotiation within and across national borders.

description: We present high spatial resolution ($52$ au) observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 made using the Atacama Large Millimeter/sub-millimeter Array (ALMA). This O-type HMYSO is located at 2.38 kpc and it is associated with a luminosity of $1.5\times10^5 L_\odot$. We detect circumstellar emission from the H$38β$ hydrogen recombination line showing a compact structure rotating perpendicularly to the previously detected radio jet. We interpret this emission as tracing a photo-ionized accretion disk around the HMYSO. While this disk-like structure seems currently too small to sustain continued accretion, the data present direct observational evidence of how disks can effectively survive the photo-ionization feedback from young high-mass stars. We also report the detection of a low-mass young stellar object in the vicinity of the HMYSO and suggest that it forms a high-mass and low-mass star binary system.

description: Working with a non-stationary stream of data requires for the analysis system to evolve its model (the parameters as well as the structure) over time. In particular, concept drifts can occur, which makes it necessary to forget knowledge that has become obsolete. However, the forgetting is subjected to the stability-plasticity dilemma, that is, increasing forgetting improve reactivity of adapting to the new data while reducing the robustness of the system. Based on a set of inference rules, Evolving Fuzzy Systems-EFS-have proven to be effective in solving the data stream learning problem. However tackling the stability-plasticity dilemma is still an open question. This paper proposes a coherent method to integrate forgetting in Evolving Fuzzy System, based on the recently introduced notion of concept drift anticipation. The forgetting is applied with two methods: an exponential forgetting of the premise part and a deferred directional forgetting of the conclusion part of EFS to preserve the coherence between both parts. The originality of the approach consists in applying the forgetting only in the anticipation module and in keeping the EFS (called principal system) learned without any forgetting. Then, when a drift is detected in the stream, a selection mechanism is proposed to replace the obsolete parameters of the principal system with more suitable parameters of the anticipation module. An evaluation of the proposed methods is carried out on benchmark online datasets, with a comparison with state-of-the-art online classifiers (Learn++.NSE, PENsemble, pclass) as well as with the original system using different forgetting strategies.

description: Mit der Entwicklung inklusiver Schulen geht die Entwicklung inklusiven Unterrichts einher. Dessen Umsetzung wird von Lehrpersonen als Herausforderung erlebt und sie fühlen sich teilweise überfordert, wenn sie inklusiven Unterricht umsetzen sollen. Erschwerend kommt hinzu, dass auch der Wissenschaftsdiskurs zu inklusivem Unterricht komplex ist und sich bisher kein gemeinsames Verständnis durchsetzen konnte, das übergreifend klärt, wie inklusiver Unterricht umzusetzen ist. In der Auseinandersetzung mit inklusivem Unterricht gibt es zudem noch eine weitere wesentliche Leerstelle, denn bis anhin wurden Schüler*innen hauptsächlich als Datenquellen in dessen Erforschung einbezogen, aber nur selten als Expert*innen, obwohl es gute Argumente dafür geben würde. Vor diesem Hintergrund geht der Artikel anhand empirischen Materials der Frage nach, welchen Beitrag die Schüler*innen zur Entwicklung inklusiven Unterrichts leisten können. Das Material stammt aus einem partizipativen Unterrichtsentwicklungsprojekt und zeigt auf, dass Schüler*innen die Entwicklung und Konzeptionierung inklusiven Unterrichts aktiv mitgestalten können. Sie analysieren dabei Problemstellungen aus ihrer persönlichen Perspektive und liefern gehaltvolle Ideen zur Unterrichtsentwicklung. Sowohl die Analysen als auch die Entwicklungsideen lassen sich an den Wissenschaftsdiskurs anschließen und bilden zugleich einen Mehrwert, da sie die Perspektive von Lehrpersonen und Forschenden mit neuen Sichtweisen ergänzen.

description: We study spanning diverging forests of a digraph and related matrices. It is shown that the normalized matrix of out forests of a digraph coincides with the transition matrix in a specific observation model for Markov chains related to the digraph. Expression are given for the Moore-Penrose generalized inverse and the group inverse of the Kirchhoff (Laplacian) matrix. These expressions involve the matrix of maximum out forest of the digraph. Every matrix of out forests with a fixed number of arcs and the normalized matrix of out forests are represented as polynomials in the Kirchhoff matrix; with the help of these identities new proofs are given for the matrix-forest theorem and some other statements. A connection is specified between the forest dimension of a digraph and the degree of an annihilating polynomial for the Kirchhoff (Laplacian) matrix. Some accessibility measures for digraph vertices are considered. These are based on the enumeration of spanning forests.

description: Seit den 1990er Jahren hat sich die Forderung nach inklusiver Bildung im internationalen Kontext als Entwicklungsziel für Bildungssysteme durchgesetzt (Köpfer, Powell & Zahnd, 2021). Die Zielsetzung geht mit der Aufhebung räumlich separierter Schulangebote einher, ist damit aber noch nicht erreicht. Neben der physischen Präsenz aller Schüler*innen in einer Schule erfordert die erfolgreiche Umsetzung Inklusiver Bildung auch einen Unterricht, der von der Vielfalt der Schüler*innen ausgeht und gemeinsames Lernen ermöglicht. Damit einher geht auch die Ermöglichung der sozialen Teilhabe am Klassenleben für alle Schüler*innen. Gerade die Umsetzung eines inklusiven Unterrichts, der diese Bedingungen erfüllt, ist eine Herausforderung.

description: In fractional quantum Hall physics, the Hilbert space is projected to a single Landau level and the entire Hamiltonian consists of just the projected inter-electron interaction. Haldane's pseudopotential formalism has been an extremely useful tool both for understanding these interactions, and for understanding the quantum Hall states that result. In the current paper we consider the analogue of this pseudopotential construction that results from general M-body interactions rather than the usual (Coulomb) two-body interaction.

description: For better data availability and accessibility while ensuring data secrecy, organizations often tend to outsource their encrypted data to the cloud storage servers, thus bringing the challenge of keyword search over encrypted data. In this paper, we propose a novel authorized keyword search scheme using Role-Based Encryption (RBE) technique in a cloud environment. The contributions of this paper are multi-fold. First, it presents a keyword search scheme which enables only the authorized users, having proper assigned roles, to delegate keyword-based data search capabilities over encrypted data to the cloud providers without disclosing any sensitive information. Second, it supports a multi-organization cloud environment, where the users can be associated with more than one organization. Third, the proposed scheme provides efficient decryption, conjunctive keyword search and revocation mechanisms. Fourth, the proposed scheme outsources expensive cryptographic operations in decryption to the cloud in a secure manner. Fifth, we have provided a formal security analysis to prove that the proposed scheme is semantically secure against Chosen Plaintext and Chosen Keyword Attacks. Finally, our performance analysis shows that the proposed scheme is suitable for practical applications.

description: The effective spin pressure induced by an electric current on a domain wall in a ferromagnet is determined using a simple classical model, which allows us to extend previous theories to arbitrary domain wall widths. In particular, the role of spatially non-uniform components of the torques are analyzed in detail. We find that the effect of the current is mainly to distort the domain wall which should enhance de-pinning. We also find that in the limit of thin domain walls the current-induced pressure changes sign.

description: Shock wave lithotripsy (SWL) has been widely used for non-invasive treatment of kidney stones. Cavitation plays an important role in stone fragmentation, yet may also contribute to renal injury during SWL. It is therefore crucial to determine the spatiotemporal distributions of cavitation activities to maximize stone fragmentation while minimizing tissue injury. Traditional cavitation detection methods include high-speed optical imaging, active cavitation mapping (ACM), and passive cavitation mapping (PCM). While each of the three methods provides unique information about the dynamics of the bubbles, PCM has most practical applications in biological tissues. To image the dynamics of cavitation bubble collapse, we previously developed a sliding-window PCM (SW-PCM) method to identify each bubble collapse with high temporal and spatial resolution. To further validate and optimize the SW-PCM method, in this work, we have developed tri-modality cavitation imaging that includes 3D high-speed optical imaging, ACM, and PCM seamlessly integrated in a single system. Using the tri-modality system, we imaged and analyzed laser-induced single cavitation bubbles in both free and constricted space and shockwave-induced cavitation clusters. Collectively, our results have demonstrated the high reliability and spatial-temporal accuracy of the SW-PCM approach, which paves the way for future in vivo applications on large animals and humans in SWL.
The Hawaiian Hoary Bat: Challenges and Solutions for Incidental Take Permitting and Implementing Consistent and Effective Mitigation

description: The Hawaiian hoary bat or ‘ōpe‘ape‘a (Lasiurus cinereus semotus) is listed as endangered under the federal Endangered Species Act and Hawai‘i state endangered species law. Knowledge regarding the ‘ōpe‘ape‘a is sparse due to its life history traits as a cryptic and solitary tree-roosting bat. This presents challenges to regulators and managers charged with issuing Incidental Take Licenses and developing the accompanying Habitat Conservation Plans
(HCPs). HCPs must ensure that licensed activities do not appreciably reduce the likelihood of survival and recovery of listed species through establishment of impact avoidance and minimization measures, as well as measures to mitigate take via conservation efforts. Mitigation must be consistent with recovery goals and must provide a net benefit to the species affected. Advancements in ecological research on both Hawaiian and mainland hoary bats have led to a better understanding of this species in recent years, but have also led to dramatic inconsistencies in mitigation practices between existing HCPs. The inconsistent scale and cost of mitigation makes it difficult to measure the impact of mitigation efforts on ‘ōpe‘ape‘a recovery across a large number of disparate projects.

The Endangered Species Recovery Committee (ESRC), an advisory committee to the Board of Land and Natural Resources regarding HCP approval, has acknowledged the challenges and inconsistencies regarding HCPs and ‘ōpe‘ape‘a. The ESRC therefore requested a workshop in April 2015 to bring together government regulators, ecological researchers, consultants, industry personnel, and members of the public to discuss issues ranging from take avoidance, research priorities, to future mitigation strategies. The workshop goal will be to provide  cohesive, consistent guidelines to developers and regulators attempting to avoid, minimize, and mitigate for incidental bat take. This poster will provide an overview and background of the ‘ōpe‘ape‘a and provide an example of regulatory processes to seek clarity and guidance where data is lacking.

description: We study the breakpoint region on the outermost branch of current-voltage characteristics of the stacks with different number of intrinsic Josephson junctions. We show that at periodic boundary conditions the breakpoint region is absent for stacks with even number of junctions. For stacks with odd number of junctions and for stacks with nonperiodic boundary conditions the breakpoint current is increased with number of junctions and saturated at the value corresponding to the periodic boundary conditions. The region of saturation and the saturated value depend on the coupling between junctions. We explain the results by the parametric resonance at the breakpoint and excitation of the longitudinal plasma wave by the Josephson oscillations. A way for the diagnostics of the junctions in the stack is proposed.

description: We study the transport properties of low-energy (quasi)particles ballistically traversing normal and Andreev two-dimensional open cavities with a Sinai-billiard shape. We consider four different geometrical setups and focus on the dependence of transport on the strength of an applied magnetic field. By solving the classical equations of motion for each setup we calculate the magnetoconductance in terms of transmission and reflection coefficients for both the normal and Andreev versions of the billiard, calculating in the latter the critical field value above which the outgoing current of holes becomes zero.

description: In McCarthy et al. (2007, astro-ph/0701335) we present an analysis of entropy generation during cluster mergers, using SPH simulations. This conference proceeding contribution summarizes some of the most important findings of that paper, without all the technical details. Our main result is that during cluster mergers, entropy is generated in two major shock episodes, that heat the gas from the inside-out, in a way that distributes most of the energy within the more massive clump. This is different from the "onion-skin" model adopted in many simple analytic models of cluster formation.

description: ROSC hastalarında O2 tedavisi uygularken hiperoksiden kaçınmak çok önemli. Hiperoksinin vazokonstrüksiyona ve serbest O2 radikallerinin oluşumuna sebep olabileceği akılda tutulmalıdır. Post kardiyak arrest ROSC’lu hastalarda hipotansiyondan kaçınmak gerekir ve hipotansiyon ivedilikle tedavi edilmelidir. Unutmayalım ki; bu hastalar, kardiyak arreste sebep olan etyolojiye veya iskemi reperfüzyon yaralanmasına sekonder olarak, genellikle hipotansiflerdir ve kardiyak arrest yönetiminde kullanılan vazoaktif ilaç (genellikle norepinefrin) etkilerinin azaldığı zaman dilimlerinde hastaların TA değerleri düştüğünü de akılda tutmak gerekir. Kardiyak arrestin en sık sebebi koroner arter hastalığıdır (KAH). Ancak post kardiyak arrest ROSC hastaların hangilerinin kardiyak kateterizasyondan fayda göreceğini öngörmek kolay değildir.

description: We investigate the wind of lambda And, a solar-mass star that has evolved off the main sequence becoming a sub-giant. We present spectropolarimetric observations and use them to reconstruct the surface magnetic field of lambda And. Although much older than our Sun, this star exhibits a stronger (reaching up to 83 G) large-scale magnetic field, which is dominated by the poloidal component. To investigate the wind of lambda And, we use the derived magnetic map to simulate two stellar wind scenarios, namely a polytropic wind (thermally-driven) and an Alfven-wave driven wind with turbulent dissipation. From our 3D magnetohydrodynamics simulations, we calculate the wind thermal emission and compare it to previously published radio observations and more recent VLA observations, which we present here. These observations show a basal sub-mJy quiescent flux level at ~5 GHz and, at epochs, a much larger flux density (>37 mJy), likely due to radio flares. By comparing our model results with the radio observations of lambda And, we can constrain its mass-loss rate Mdot. There are two possible conclusions. 1) Assuming the quiescent radio emission originates from the stellar wind, we conclude that lambda And has Mdot ~ 3e-9 Msun/yr, which agrees with the evolving mass-loss rate trend for evolved solar-mass stars. 2) Alternatively, if the quiescent emission does not originate from the wind, our models can only place an upper limit on mass-loss rates, indicating that Mdot

description: We prove various iteration theorems for forcing classes related to subproper and subcomplete forcing, introduced by Jensen. In the first part, we use revised countable support iterations, and show that 1) the class of subproper, ${}^ωω$-bounding forcing notions, 2) the class of subproper, $T$-preserving forcing notions (where $T$ is a fixed Souslin tree) and 3) the class of subproper, $[T]$-preserving forcing notions (where $T$ is an $ω_1$-tree) are iterable with revised countable support. In the second part, we adopt Miyamoto's theory of nice iterations, rather than revised countable support. We show that this approach allows us to drop a technical condition in the definitions of subcompleteness and subproperness, still resulting in forcing classes that are iterable in this way, preserve $ω_1$, and, in the case of subcompleteness, don't add reals. Further, we show that the analogs of the iteration theorems proved in the first part for RCS iterations hold for nice iterations as well.
