description: Recent generalizations of the Camassa-Holm equation are studied from the point of view of existence of global solutions, criteria for wave breaking phenomena and integrability. We provide conditions, based on lower bounds for the first spatial derivative of local solutions, for global well-posedness for the family under consideration in Sobolev spaces. Moreover, we prove that wave breaking phenomena occurs under certain mild hypothesis. Regarding integrability, we apply the machinery developed by Dubrovin [Commun. Math. Phys. 267, 117--139 (2006)] to prove that there exists a unique bi-hamiltonian structure for the equation only when it is reduced to the Dullin-Gotwald-Holm equation. Our results suggest that a recent shallow water model incorporating Coriollis efects is integrable only in specific situations. Finally, to finish the scheme of geometric integrability of the family of equations initiated in a previous work, we prove that the Dullin-Gotwald-Holm equation describes pseudo-spherical surfaces.

Implications of the mass $M=2.17^{+0.11}_{-0.10}$M$_\odot$ of PSR~J0740+6620 on the Equation of State of Super-Dense Neutron-Rich Nuclear Matter

description: We study implications of the very recently reported mass $M=2.17^{+0.11}_{-0.10}$M$_\odot$ of PSR~J0740+6620 on the Equation of State (EOS) of super-dense neutron-rich nuclear matter with respect to existing constraints on the EOS based on the mass $M=2.01\pm 0.04$M$_\odot$ of PSR~J0348+0432, the maximum tidal deformability of GW170817 and earlier results of various terrestrial nuclear laboratory experiments. The lower limit of the skewness $J_0$ measuring the stiffness of super-dense isospin-symmetric nuclear matter is raised raised from about -220 MeV to -150 MeV, reducing significantly its current uncertainty range. The lower bound of the high-density symmetry energy also increases appreciably leading to a rise of the minimum proton fraction in neutron stars at $β$-equilibrium from about 0 to 5\% around three times the saturation density of nuclear matter. The difficulties for some of the most widely used and previously well tested model EOSs to predict simultaneously both a maximum mass higher than 2.17 M$_\odot$ and a pressure consistent with that extracted from GW170817 present some interesting new challenges for nuclear theories.

Soft and hard QCD dynamics in hadroproduction of charmonium

description: Both hard and soft QCD dynamics are important in charmonium production, as presented here through a next-to-leading order QCD matrix element calculation combined with the colour evaporation model. Observed $x_F$ and $p_\perp$ distributions of $J/ψ$ in hadroproduction at fixed target and $p\bar{p}$ collider energies are reproduced. Quite similar results can also be obtained in a more phenomenologically useful Monte Carlo event generator where the perturbative production of \ccbar pairs is instead obtained through leading order matrix elements and the parton shower approximation of the higher order processes. The soft dynamics may alternatively be described by the soft colour interaction model, originally introduced in connection with rapidity gaps. We also discuss the relative rates of different charmonium states and introduce an improved model for mapping the continuous \ccbar mass spectrum on the physical charmonium resonances.

description: Superfluid stiffness $ρ_s$ is a defining characteristic of the superconducting state, allowing phase coherence and supercurrent. It is accessible experimentally through the penetration depth. Coexistence of $d$-wave superconductivity with other phases in underdoped cuprates, such as antiferromagnetism (AF) or charge-density waves (CDW), may drastically alter $ρ_s$. To shed light on this physics, the zero-temperature value of $ρ_s=ρ_{zz}$ along the $c$-axis was computed for different values of Hubbard interaction $U$ and different sets of tight-binding parameters describing the high-temperature superconductors YBCO and NCCO. We used Cellular Dynamical Mean-Field Theory for the one-band Hubbard model with exact diagonalization as impurity solver and state-of-the-art bath parametrization. We conclude that Mott physics plays a dominant role in determining the superfluid stiffness on the hole-doped side of the phase diagram. On the electron-doped side, antiferromagnetism wins over superconductivity near half-filling. But upon approaching optimal electron-doping, homogeneous coexistence between superconductivity and antiferromagnetism causes the superfluid stiffness to drop sharply. Hence, on the electron-doped side, it is competition between antiferromagnetism and $d$-wave superconductivity that plays a dominant role in determining the value of $ρ_{zz}$ near half-filling. At large overdoping, $ρ_{zz}$ behaves in a more BCS-like manner in both the electron- and hole-doped cases. We comment on some qualitative implications of these results for the superconducting transition temperature.

The new compound, eucommiaflavone (1) was structurally elucidated by various spectroscopic analyses. In particular, Mo2(OAc)4-induced circular dichroism (ICD) analysis was applied to determine the absolute configuration of 1. Furthermore, five flavonoids (4, 9, 11, 13, and 15) revealed significant in vitro hepatoprotective activity against D-galactosamine-induced cytotoxicity in human hepatoma HepG2 cells.

description: Searches for supersymmetric partners of top and bottom quarks are presented using data taken by the DELPHI experiment at LEP in 1997 and 1998. No deviations from standard model expectations are observed in these data sets, which are taken at centre-of-mass energies of 183 GeV and 189 GeV and correspond to integrated luminosities of 54 pb^{-1} and 158 pb^{-1}. These results are used in combination with those obtained by DELPHI at lower centre-of-mass energies to exclude regions in the squark-neutralino mass plane at 95% confidence level.

description: A pair of Majorana zero modes (MZMs) constitutes a nonlocal qubit whose entropy is $\log 2$. Upon strongly coupling one of the constituent MZMs to a reservoir with a continuous density of states, a universal entropy change of $\frac{1}{2}\log 2$ is expected to be observed across an intermediate temperature plateau. We adapt the entropy-measurement scheme that was the basis of a recent experiment [Hartman et. al., Nat. Phys. 14, 1083 (2018)] to the case of a proximitized topological system hosting MZMs, and propose a method to measure this $\frac{1}{2}\log 2$ entropy change --- an unambiguous signature of the nonlocal nature of the topological state. This approach offers an experimental strategy to distinguish MZMs from non-topological states.

 Nach dem ersten Bericht eines Fundes des Tellerkrauts in Österreich in einem Garten in Ried im Innkreis (HOHLA 2006b) konnte nun auch ein weiteres, "klassisches" Vorkommen in einer Innviertler Baumschule festgestellt werden. "Klassisch" deswegen, da diese Art in Bayern und Baden-Württemberg vor allem in Baumschulen verschleppt vorgefunden wurde (SEYBOLD 1993, SCHÖNFELDER & BRESINSKY 1990). HETZEL (2006) beobachtete für Oberfranken eine " Claytonia perfoliata -Gesellschaft" in Gärtnereien, Baumschulen, Friedhöfen, Privatgärten, Strauchrabatten oder unter Robinien. Ältere, stabile Bestände stellte er vor allem unter Gebüschen oder Gehölzen mit Galium aparine, Lamium album und Urtica dioica fest, unbeständige Vorkommen auf jüngeren, regelmässig gepflegten Flächen. Das Tellerkraut gilt dort inzwischen als eingebürgert.
 Als unmittelbare Begleitarten der rund drei Dutzend Claytonia perfoliata- Individuen in Reichersberg wurden nur Veronica hederifolia und Stellaria media notiert, da sich diese Stelle fast frei von sonstiger Vegetation zeigte. Ein weiterer österreichischer Fund des Tellerkrauts kann nun auch aus Wien gemeldet werden, wo diese Art von R. Moosbeckhofer im 10. Bezirk am Gehsteig in Asphalt-Ritzen gefunden wurde (schriftl. Mitt. F. TOD).

description: Interesa ante todo, regresar al Perú de 2016 para reconstruir y poder explicar el movimiento social de Ni Una Menos (NUM) en un escenario profundamente dañado por el incremento de violencia contra las mujeres y de elevadas tasas de feminicidios. Frente a esto, pudo notarse que diferentes grupos y colectivos decidieran crear desde la redes una alerta sobre el tema. La solución planteaba que se convocaría a una movilización nacional que pudiese dar cuenta de la crítica situación de miles de mujeres en el país. Esta pretensión, finalmente, detonó el 13 de agosto de 2016 ante la impunidad por parte del Poder Judicial al dictaminar fechas antes dos sentencias benignas. De eso trata NUM, movimiento que procede de una radiografía inadmisible y de un cuadro acumulado por inmensas denuncias relativas por actos de violencia o de feminicidios presentados, en donde las mujeres, mayoritariamente, se posicionaban en medio de todos estos problemas. En esa tensa situación, es que sucede que una errada decisión institucional, pudo definitivamente, ser el punto explosivo y el inicio de un caudal de reclamos y encuentros devenidos desde la indignación y la intervención de la colectiva femenina o de las colectivas que reunía NUM.
Seating the place : magic and embodiment on the Lelet Plateau, New Ireland (Papua New Guinea)

description: This thesis explores and describes the lived world of the people inhabiting the Lelet Plateau in central New Ireland, Papua New Guinea. Its particular focus is embodiment and the forms of corporeal imagery in magical belief, interpreted from a perspective that draws on Bakhtin's dialogism and Merleau-Ponty's phenomenology. Bakhtin argues that dialogic relations extend far beyond dialogic speech in the narrow sense and are imbued in the entire realm of living thought. For him there is no unitary or self-constituting subject who exists in and by him or herself. I argue similarly for a relational or dialogical theory of personhood which sees the person as constituted in the social world, in relations with others. Among the Lelet sociality is crucial in defining humanness. I follow Merleau-Ponty in seeing the subject as embodied, and suggest that the consciousness of the Lelet person is not radically separated from bodily being, as it is in modem western thought, but is integrally bound up with it. The Lelet person is very much a body-subject whose consciousness of self as acting subject is integrally connected to the corporeal component of his or her being. I draw on the insights of Merleau-Ponty to elaborate a theory of the body which points to the significance of movement and action as the basis of intentionality. I argue that the movement of the body in action is central to the Lelet imagination because it is integral to the constitution of the person. The immobile state of the sitting body is opposed to the more mobile state of movement in numerous contexts. Throughout, I explore the polyvalent meanings of such bodily images and the ways in which they are reconfigured in different contexts. The body, thus, is the medium through which the Lelet construct personhood and identity. Because of this, power relations are often concerned with the body. The renown of a person is dependent on the processes of value creation in which bodily power or bodily movement are transformed into products which are then circulated and exchanged with others. Because the body is central to the constitution of the person and the creation of value it is the target for those who seek to attack or control others.
Dynamical system analysis of generalized energy-momentum-squared gravity

description: In this work we have investigated the dynamics of a recent modification to the general theory of relativity, the energy-momentum squared gravity model $f(R,\mathbf{T^2})$, where $R$ represents the scalar curvature and $\mathbf{T^2}$ the square of the energy-momentum tensor. By using dynamical system analysis for various types of gravity functions $f(R,\mathbf{T^2})$, we have studied the structure of the phase space and the physical implications of the energy-momentum squared coupling. In the first case of functional where $f(R,\mathbf{T^2})=f_0 R^n(\mathbf{T^2})^m$, with $f_0$ constant, we have shown that the phase space structure has a reduced complexity, with a high sensitivity to the values of the $m$ and $n$ parameters. Depending on the values of the $m$ and $n$ parameters, the model exhibits various cosmological epochs, corresponding to matter eras, solutions associated with an accelerated expansion, or decelerated periods. The second model studied corresponds to the $f(R,\mathbf{T^2})=αR^n+β\mathbf{(T^2)}^m$ form with $α, β$ constant parameters. In this case, a richer phase space structure is obtained which can recover different cosmological scenarios, associated to matter eras, de--Sitter solutions, and dark energy epochs. Hence, this model represents an interesting cosmological model which can explain the current evolution of the Universe and the emergence of the accelerated expansion as a geometrical consequence.

Stability of quantum states of finite macroscopic systems against classical noises, perturbations from environments, and local measurements

description: We study the stability of quantum states of macroscopic systems of finite volume V, against weak classical noises (WCNs), weak perturbations from environments (WPEs), and local measurements (LMs). We say that a pure state is `fragile' if its decoherence rate is anomalously great, and `stable against LMs' if the result of a LM is not affected by another LM at a distant point. By making full use of the locality and huge degrees of freedom, we show the following: (i) If square fluctuation of every additive operator is O(V) or less for a pure state, then it is not fragile in any WCNs or WPEs. (ii) If square fluctuations of some additive operators are O(V^2) for a pure state, then it is fragile in some WCNs or WPEs. (iii) If a state (pure or mixed) has the `cluster property,' then it is stable against LMs, and vice versa. These results have many applications, among which we discuss the mechanism of symmetry breaking in finite systems.

description: El Cambio Climático (CC) representa para la sociedad actual uno de los mayores problemas y desafíos globales que impulsa una alta necesidad de intervenir desde diferentes espacios. De este modo, el estudio pretende analizar las percepciones sobre el CC en estudiantes de educación secundaria. Para esto, se apela principalmente, a la teoría de las representaciones sociales y a la dinámica de una mesa de diálogo orientado por una ruta de cuatro preguntas moldeables de posicionalidad, significancia, desafío y valoración crítica sobre un escenario en el que el asunto a tratar estuviese condensado, más definidamente, en los efectos y daños globales desprendidos por el CC. Los resultados inscriben, que tales réplicas desembocadas por los diferentes grupos signatarios del panel, asumen que nada niega y contrapone que el CC resulta, finalmente, ser uno de los peores problemas globales que enfrenta toda capacidad de respuesta. De ser así, los participantes plantean que, pese a ello, aún no se ha legitimado el aprendizaje ilustrativo y necesario del CC al interior de las aulas. En ese reparo, la idea de desafiar desde el espacio pedagógico al colosal tema, puede no ser suficiente sino se incluye o refuerza su transversalidad en todo el proceso educativo.

description: A simple method to compute QED bound state properties is presented, in which binding energy effects are treated non-perturbatively. It is shown that to take the effects of all ladder Coulomb photon exchanges into account, one can simply perform the derivative of standard QED amplitudes with respect to the external momentum. For example, the derivative of the light-by-light scattering amplitude gives an amplitude for orthopositronium decay to three photons where any number of Coulomb photon exchanges between the e-e+ is included. Various applications are presented. From them, it is shown that binding energy must be treated non-perturbatively in order to preserve the analyticity of positronium decay amplitudes. Interesting perspectives for quarkonium physics are briefly sketched.

description: In this exploratory study, near-threshold scattering of $D$ and $\bar{D}^*$ meson is investigated using lattice QCD with $N_f=2+1+1$ twisted mass fermion configurations. The calculation is performed within the coupled-channel Lüscher's finite-size formalism. The study focuses on the channel with $I^G(J^{PC})=1^+(1^{+-})$ where the resonance-like structure $Z_c(3900)$ was discovered. We first identify the most relevant two channels of the problem and the lattice study is performed within the two-channel scattering model. Combined with a two-channel Ross-Shaw theory, scattering parameters are extracted from the energy levels by solving the generalized eigenvalue problem. Our results on the scattering length parameters suggest that, at the particular lattice parameters that we studied, the best fitted parameters do not correspond to a peak behavior in the elastic scattering cross section near the threshold. Furthermore, within the zero-range Ross-Shaw theory, the scenario of a narrow resonance close to the threshold is disfavored beyond $3σ$ level.

description: Recent deep Chandra LETG+HRC-S observations suggest the possibility that RX J1856.5--3754 is a compact star whose radiation radius is 3.8--8.2 km. In this paper, we systematically calculate the mass-radius relations of quark stars within the bag model. Assuming that RX J1856.5--3754 is a pure quark star, we derive an upper limit on its mass for various sets of the bag-model parameters.

 Neu für Tirol. Die ersten Salzburger Nachweise zu dieser häufig als Bodendecker in Rabatten gezogenen, aus China stammenden Zierpflanze wurden von SCHRÖCK et al. (2004a) angeführt, die darauf hinweisen, dass Verwilderungen v.a. in Siedlungsnähe zu beobachten sind. Nunmehr werden weitere naturalisierte Vorkommen aus Salzburg vorgestellt, die zeigen, dass diese Art auch bereits inneralpin anzutreffen ist und gelegentlich abseits von menschlichen Siedlungen in mehr oder weniger naturnahen Biotopen wie Extensivweiden oder Waldränder auftreten kann. Auch Felsstandorte werden gelegentlich besiedelt, wie der Nachweis aus Grein an der Donau belegt. In Tirol war Cotoneaster dammeri bislang noch nicht nachgewiesen (vgl. WALTER et al. 2002), so dass der Fund in Lienz dem Erstnachweis für dieses Bundesland entspricht.

Constructing a Coherent Philosophical Basis for Research Ethics

description: The purpose of this dissertation is to identify some of the most pressing problems in the dominant contemporary approach to research ethics, and to devise an alternative approach that avoids these problems. I contend that the fundamental ethical values invoked in human research are often appealed to in contradictory or ambiguous ways, or in ways that do not adequately capture or do not show an adequate understanding of the specific ethical concerns of human research. One significant problem in this domain is that values for ethical research are often unreflectively imported from medical therapy, producing ill-suited guidelines that cannot capture the different ethical situations that arise in the context of research. Furthermore, ethical guidelines in this area are often not developed with a sufficient understanding of the deep philosophical issues that they invoke. I suggest that we can address these problems through examining the fundamental ethical concerns of research on a philosophical level. This method will reveal severe problems with the approach to two of the ethical values underlying research; beneficence and respect for autonomy (or respect for persons). Once the nature of these problems has been revealed, and with reference to ethical problems that typically arise in the domain of research, I construct a coherent philosophical foundation for research ethics, which both avoids these deep-seated problems and better captures the ethical issues that arise in the domain of human research. I argue that we need to radically depart from the values of beneficence and autonomy/respect for persons as they are currently understood in the guidelines. We need an idea of beneficence that is clearly distinct from that which is used in the therapeutic medical context from which this notion is currently drawn. I also contend that we need to move away from autonomy as a central value in research ethics. I posit an alternative choice-based approach to informed consent which is concerned both with respecting agents’ freedom of choice, and also with their wellbeing, as providing a good means of protecting and promoting the interests of the individual research subject. Although these two imperatives are often thought to clash on a fundamental level, I will show that, in research ethics, they can be reconciled with minimal conflict. Though this represents a departure from the ethics of medical therapy, this approach is far more suited to the context of research. This theoretical basis for informed consent can help to clarify the ethical problems that are specific to this domain and provide us with relevant ethical guidance in research ethics.

 Neu für Kärnten. Auf diese häufig verwildernde, in früherer Zeit oft mit Cotoneaster horizontalis verwechselte Steinmispel wird seit der ersten Angabe für Österreich (STÖHR 2002) vermehrt hingewiesen, zuletzt bei ESSL (2006ac), SCHINNINGER (2006) und STÖHR et al. (2006). Cotoneaster divaricatus verwildert mindestens so häufig wie C. horizontalis, fehlt aber bei FISCHER et al. (2005), so dass Bestimmungen mit dieser Flora meist zwangsläufig zu C. horizontalis führen müssen. Aufgrund des obigen Nachweises aus Klagenfurt wird hier der Erstfund für Kärnten mitgeteilt, zudem war diese Art noch nicht aus Osttirol bekannt. Wie die Funde dem Virgental und den Salzburger Gebirgsgauen zeigen, kann selbst inneralpin mit Verwilderungen dieser Pflanze gerechnet werden. Das Vorkommen in Prägraten ist bislang das höchstgelegene von Cotoneaster divaricatus in Österreich.

The curious case of the designer vagina. Genital satisfaction, pornography and self-objectification: an empirical investigation

description: Many popular writers and academic theoreticians have postulated that pornography is the main, or only driver of labiaplasty. In this model, that we have termed the Porn Thesis, women consume pornography, compare themselves unfavourably with the women depicted, become dissatisfied with their genitals and seek surgery. We hypothesised that common historical bases underpin both modern cosmetic labiaplasty and pornographic aesthetic conventions. The Porn Thesis has never been tested empirically. The five studies that comprise this thesis investigated the accuracy and utility of the Porn Thesis as a model for genital satisfaction, and proposed and evaluated alternative predictors. The study findings indicated that the Porn Thesis is not a useful model for understanding genital satisfaction. Our initial model, based only on the Porn Thesis and therefore including only demographic predictors and pornography consumption did not account for the variance in genital satisfaction. Analysis of the open-ended questions indicated that women were assessing their bodies in an holistic fashion, rather than comparing themselves to outside images. Accordingly, we identified Objectification Theory as a potential predictor of genital satisfaction. Objectification Theory posits that exposure to sexually objectifying experiences and media (including pornography) is deleterious to the psychological wellbeing of women. Unlike the Porn Thesis, Objectification Theory has testable outcomes. Additionally, self-objectification peaks at the time at which most girls are experiencing pornography for the first time. We assessed the accuracy of Objectification Theory through a systematic review of the literature investigating the role of self-objectification in the development of depression. We found that empirical work largely supported the predictions of the theory, although many studies failed to include common risk factors for depression. We then deployed a second study investigating predictors for genital satisfaction including pornography consumption, self-objectification and other predictors. We found that self-objectification was the only modifiable factor that remained in the model. This has implications for clinicians and policy-makers. Lastly, we investigated the role of self-objectification in depression and disordered eating in the context of other predictors. The Objectification Theory model was not supported for the depression outcome. However, it was supported with regard to disordered eating. Overall, we found no support for the assertion that pornography consumption impacts negatively on women’s genital self-assessment. However, self-objectification, as a model that incorporates media and bodily evaluation may have practical implications in this field.
Update of the search for charginos nearly mass-degenerate with the lightest neutralino

description: The data collected by DELPHI in 1998 at the centre-of-mass energy of 189 GeV have been used to update the search for charginos nearly mass-degenerate with the lightest supersymmetric particle, which is assumed to be the lightest neutralino. Mass differences below ΔM = 3 GeV/c^2 are considered. No excess of events with respect to the Standard Model expectation has been observed, and exclusions in the plane of ΔM versus chargino mass are given. The new ΔM independent lower limit on the mass of the chargino is 62.4 GeV/c^2 in the higgsino scenario (which includes the gaugino mass unification scenario), if all sfermions are heavier than the lightest chargino. In the approximation of large sfermion masses the limit is 59.8 GeV/c^2, independently of the field content.

description: CeRhIn$_{5}$ is a Kondo-lattice prototype in which a magnetic field B$\bf{^{\ast}\simeq}$ 30 T induces an abrupt Fermi-surface (FS) reconstruction and pronounced in-plane electrical transport anisotropy all within its antiferromagnetic state. Though the antiferromagnetic order at zero field is well-understood, the origin of an emergent state at B$^{\ast}$ remains unknown due to challenges inherent to probing states microscopically at high fields. Here, we report low-temperature Nuclear Magnetic Resonance (NMR) measurements revealing a discontinuous decrease in the $^{115}$In formal Knight shift, without changes in crystal or magnetic structures, of CeRhIn$_{5}$ at fields spanning B$^{\ast}$. We show that the emergent state above B$^{\ast}$ results from a change in Ce's 4f orbitals that arises from field-induced evolution of crystal-electric field (CEF) energy levels. This change in orbital character enhances hybridisation between the 4f and the conduction electrons (c.e.) that leads ultimately to an itinerant quantum-critical point at B$\bf{_{c0} \simeq}$ 50 T.
