description: Die Datenbasis von 56 ökologisch wirtschaftenden Betrieben im Jahr 2018 war Ausgangspunkt, um betriebsindividuelle Vorschläge zur Optimierung der Nährstoffversorgung bei verschiedenen Nutzungsformen von Schweinen und Geflügel, einem effizienten Ressourceneinsatz sowie einem auskömmlichen Betriebsergebnis zu entwickeln. Die Optimierungsstrategien basierten auf den folgenden Prämissen: bedarfsgerechte Rationen in allen Lebensabschnitten, 100 % Öko-Futtermittel, vermehrter Einsatz von heimischen Proteinträgern sowie eine ökonomische Vorzüglichkeit gegenüber der in Teil 1 dargestellten Ausgangssituation. Auf der Basis einzelbetrieblich angepasster Fütterungsstrategien konnten unter Verwendung erhöhter Mengen an heimischen Grün- und Körnerleguminosen für alle Betriebe die Prämissen eingehalten werden. In den Rationsvorschlägen wurden heterogene Ausgangsqualitäten heimischer Proteinträger gezielt durch hochwertigere Komponenten ergänzt. Die Anpassung an die veränderlichen Nährstoffansprüche der Tiere wurde durch Implementierung von Fütterungsphasen erreicht, so dass der Bedarf an hochwertigen und kostenintensiven Komponenten begrenzt wurde. So ergaben sich ökonomisch vorteilhafte Optionen. Die Ergebnisse legen nahe, dass es der einzelbetrieblichen Implementierung eines Fütterungscontrollings in Kombination mit einem überbetrieblichen Vergleich der von den Betrieben erbrachten Ressourceneffizienz bedarf, um deutliche Verbesserungen zu realisieren und die Realität der ökologischen Schweine- und Geflügelhaltung besser mit den Ansprüchen in Einklang zu bringen. Auch scheint es an der Zeit, der landwirtschaftlichen Praxis Zielvorgaben bezüglich einer bedarfsgerechten Nährstoffversorgung sowie eines noch tolerablen Niveaus an Tierverlusten als Orientierung an die Hand zu geben und in die Beratungs- und Kontrollpraxis zu integrieren.

description: In plant-pollinator communities many pollinators are potential generalists and their preferences for certain plants can change quickly in response to changes in plant and pollinator densities. These changes in preferences affect coexistence within pollinator guilds as well as within plant guilds. Using a mathematical model, we study how adaptations of pollinator preferences influence population dynamics of a two-plant-two-pollinator community interaction module. Adaptation leads to coexistence between generalist and specialist pollinators, and produces complex plant population dynamics, involving alternative stable states and discrete transitions in the plant community. Pollinator adaptation also leads to plant-plant apparent facilitation that is mediated by changes in pollinator preferences. We show that adaptive pollinator behavior reduces niche overlap and leads to coexistence by specialization on different plants. Thus, this article documents how adaptive pollinator preferences for plants change the structure and coexistence of plant-pollinator communities.

description: Low-mass stars are currently the most promising targets for detecting and characterizing habitable planets in the solar neighborhood. However, the ultraviolet (UV) radiation emitted by such stars can erode and modify planetary atmospheres over time, drastically affecting their habitability. Thus knowledge of the UV evolution of low-mass stars is critical for interpreting the evolutionary history of any orbiting planets. Shkolnik & Barman (2014) used photometry from the Galaxy Evolution Explorer (GALEX) to show how UV emission evolves for early type M stars ($>$0.35 $M_\odot$). In this paper, we extend their work to include both a larger sample of low-mass stars with known ages as well as M stars with lower masses. We find clear evidence that mid- and late-type M stars (0.08-0.35 $M_\odot$) do not follow the same UV evolutionary trend as early-Ms. Lower mass M stars retain high levels of UV activity up to field ages, with only a factor of 4 decrease on average in GALEX NUV and FUV flux density between young ($

description: Background: Significant conversations with parents are a necessary and important part of healthcare. The delivery of bad or difficult news, such as the diagnosis of a chronic health condition, requires key communication skills. This is especially true for communication between healthcare professionals and parents in paediatric settings. It is important to understand parental experiences of these conversations and what can be done to help support and improve skills in this area. Method: A systematic review evaluates studies assessing the effectiveness of interventions in improving breaking bad news skills. An empirical study uses Interpretative Phenomenological Analysis of interviews with parents to gain an in-depth understanding of parental experiences of receiving a newborn diagnosis of cystic fibrosis (CF). Results: The systematic review identified ten quantitative studies assessed to be of either moderate or high quality. Significant improvements in communication skills were found following nine of the ten interventions. These interventions shared some common features. In the empirical study, three superordinate themes emerged following interview analysis: Cognitive and Emotional Experiences; Connection; and Knowledge. Conclusions: Findings from the review suggest that there are interventions that can improve communication skills in delivering bad news in paediatric settings. Parents in the empirical study clearly recalled the period of receiving a newborn diagnosis of CF as an emotional time. Health professionals’ communication and interpersonal skills seemed to play an important role in providing containment for families. Clinical implications and directions for future research are discussed.

description: Using first-principles calculations within the generalized gradient approximation, we predicted the lattice parameters, elastic constants, vibrational properties, and electronic structure of cementite (Fe3C). Its nine single-crystal elastic constants were obtained by computing total energies or stresses as a function of applied strain. Furthermore, six of them were determined from the initial slopes of the calculated longitudinal and transverse acoustic phonon branches along the [100], [010] and [001] directions. The three methods agree well with each other, the calculated polycrystalline elastic moduli are also in good overall agreement with experiments. Our calculations indicate that Fe3C is mechanically stable. The experimentally observed high elastic anisotropy of Fe3C is also confirmed by our study. Based on electronic density of states and charge density distribution, the chemical bonding in Fe3C was analyzed and was found to exhibit a complex mixture of metallic, covalent, and ionic characters.

description: We present here the results on the physical nature a RS CVn binary KIC 7885570 and its chromospheric activity based on the Kepler Mission data. Assuming the primary component temperature, 6530 K, the temperature of the secondary component was found to be 5732+-4 K. The mass ratio of the components (q) was found to be 0.43$\pm$0.01, while the inclination ($i$) of the system 80.56+-0.01 deg. Additionally, the data were separated into 35 subsets to model the sinusoidal variation due to the rotational modulation, using the SPOTMODEL program, as the light curve analysis indicated the chromospherically active secondary component. It was found that there are generally two spotted areas, whose radii, longitudes and latitudes are rapidly changing, located around the latitudes of +50 deg and +90 deg on the active component. Moreover, 113 flares were detected and their parameters were computed from the available data. The One Phase Exponential Association function model was derived from the parameters of these flares. Using the regression calculations, the Plateau value was found to be 1.9815+-0.1177, while the half-life value was computed as 3977.2 s. In addition, the flare frequency (N1) - the flare number per hour, was estimated to be 0.00362 1/h, while flare frequency (N2) - the flare-equivalent duration emitted per hour, was computed as 0.00001. Finally, the times of eclipses were computed for 278 minima of the light curves, whose analysis indicated that the chromosphere activity nature of the system causes some effects on these minima times. Comparing the chromospheric activity patterns with the analogues of the secondary component, it is seen that the magnetic activity level is remarkably low. However, it is still at the expected level according to the B-V color index of 0.643 mag for the secondary component.

description: Many future concepts for spintronic devices are based on the current-driven motion of magnetic domain walls through nanowires. Consequently a thorough understanding of the domain wall mobility is required. However, the magnitude of the nonadiabatic component of the spin-transfer torque driving the domain wall is still debated today as various experimental methods give rise to a large range of values for the degree of nonadiabaticity. Strikingly, experiments based on vortex domain wall motion in magnetic nanowires consistently result in lower values compared to other methods. Based on the micromagnetic simulations presented in this contribution we can attribute this discrepancy to the influence of distributed disorder which vastly affects the vortex domain wall mobility, but is most often not taken into account in the models adopted to extract the degree of nonadiabaticity.

description: We present a solution to the problem of defining a counterpart in Algebraic Set Theory of the construction of internal sheaves in Topos Theory. Our approach is general in that we consider sheaves as determined by Lawvere-Tierney coverages, rather than by Grothendieck coverages, and assume only a weakening of the axioms for small maps originally introduced by Joyal and Moerdijk, thus subsuming the existing topos-theoretic results.

Optical/infrared polarised emission in X-ray binaries

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Recently, evidence for synchrotron emission in both black hole and neutron star X-ray binaries has been mounting, from optical/infrared spectral, polarimetric, and fast timing signatures. The synchrotron emission of jets can be highly linearly polarised, depending on the configuration of the magnetic field. Optical and infrared (OIR) polarimetric observations of X-ray binaries are presented in this brief review. The OIR polarimetric signature of relativistic jets is detected at levels of ~ 1-10 %, similar to AGN cores. This reveals that the magnetic geometry in the compact jets may be similar for supermassive and stellar-mass BHs. The magnetic fields near the jet base in most of these systems appear to be turbulent, variable and on average, aligned with the jet axis, although there are some exceptions. These measurements probe the physical conditions in the accretion (out)flow and demonstrate a new way of connecting inflow and outflow, using both rapid timing and polarisation. Variations in polarisation could be due to rapid changes of the ordering of the magnetic field in the emitting region, or in one case, flares from individual ejections or collisions between ejecta. It is predicted that in some cases, variable levels of X-ray polarisation from synchrotron emission originating in jets will be detected from accreting Galactic black holes with upcoming spaceborne X-ray polarimeters.

description: Let $\{μ(\cdot,t):t\geq0\}$ be the family of probability measures corresponding to the solution of the inelastic Kac model introduced in Pulvirenti and Toscani [\textit{J. Stat. Phys.} \textbf{114} (2004) 1453-1480]. It has been proved by Gabetta and Regazzini [\textit{J. Statist. Phys.} \textbf{147} (2012) 1007-1019] that the solution converges weakly to equilibrium if and only if a suitable symmetrized form of the initial data belongs to the standard domain of attraction of a specific stable law. In the present paper it is shown that, for initial data which are heavier-tailed than the aforementioned ones, the limiting distribution is improper in the sense that it has probability 1/2 "adherent" to $-\infty$ and probability 1/2 "adherent" to $+\infty$. It is explained in which sense this phenomenon is amenable to a sort of explosion, and the main result consists in an explicit expression of the rate of such an explosion. The presentation of these statements is preceded by a discussion about the necessity of the assumption under which their validity is proved. This gives the chance to make an adjustment to a portion of a proof contained in the above-mentioned paper by Gabetta and Regazzini.

description: In the 2nd Annual FOCS (1961), C. K. Chow proved that every Boolean threshold function is uniquely determined by its degree-0 and degree-1 Fourier coefficients. These numbers became known as the Chow Parameters. Providing an algorithmic version of Chow's theorem --- i.e., efficiently constructing a representation of a threshold function given its Chow Parameters --- has remained open ever since. This problem has received significant study in the fields of circuit complexity, game theory and the design of voting systems, and learning theory. In this paper we effectively solve the problem, giving a randomized PTAS with the following behavior: Theorem: Given the Chow Parameters of a Boolean threshold function f over n bits and any constant ε > 0, the algorithm runs in time O(n2 log2 n) and with high probability outputs a representation of a threshold function f' which is ε-close to f. Along the way we prove several new results of independent interest about Boolean threshold functions. In addition to various structural results, these include the following new algorithmic results in learning theory (where threshold functions are usually called "halfspaces"): An ~O(n2)-time uniform distribution algorithm for learning halfspaces to constant accuracy in the "Restricted Focus of Attention" (RFA) model of Ben-David et al. [3]. This answers the main open question of [6]. An O(n2)-time agnostic-type learning algorithm for halfspaces under the uniform distribution. This contrasts with recent results of Guruswami and Raghavendra [21] who show that the learning problem we solve is NP-hard under general distributions. As a special case of the latter result we obtain the fastest known algorithm for learning halfspaces to constant accuracy in the uniform distribution PAC learning model. For constant ε our algorithm runs in time ~O(n2), which substantially improves on previous bounds and nearly matches the Ω(n2) bits of training data that any successful learning algorithm must use.

description: We present the first detailed three-dimensional hydrodynamic implicit large eddy simulations of turbulent convection for carbon burning. The simulations start with an initial radial profile mapped from a carbon burning shell within a 15 solar mass stellar evolution model. We considered 4 resolutions from 128^3 to 1024^3 zones. These simulations confirm that convective boundary mixing (CBM) occurs via turbulent entrainment as in the case of oxygen burning. The expansion of the boundary into the surrounding stable region and the entrainment rate are smaller at the bottom boundary because it is stiffer than the upper boundary. The results of this and similar studies call for improved CBM prescriptions in 1D stellar evolution models.

description: We examine the relationship between source position stability and astrophysical properties of radio-loud quasars making up the International Celestial Reference Frame. Understanding this relationship is important for improving quasar selection and analysis strategies, and therefore reference frame stability. We construct light curves for 95 of the most frequently observed ICRF2 quasars at both the 2.3 and 8.4 GHz geodetic VLBI observing bands. Because the appearance of new quasar components corresponds to an increase in quasar flux density, these light curves alert us to potential changes in source structure before they appear in VLBI images. We test how source position stability depends on three astrophysical parameters: (1) Flux density variability at X-band; (2) Time lag between flares in S and X-bands; (3) Spectral index rms, defined as the variability in the ratio between S and X-band flux densities. We find that small time lags between S and X-band light curves, and low spectral index variability, are good indicators of position stability. On the other hand, there is no strong dependence of source position stability on flux density variability in a single frequency band. These findings can be understood by interpreting the time lag between S and X-band light curves as a measure of the size of the source structure. Monitoring of source flux density at multiple frequencies therefore appears to provide a useful probe of quasar structure on scales important to geodesy. We show how multi-frequency flux density monitoring may allow the dependence on frequency of the relative core positions along the jet to be elucidated. Knowledge of the position-frequency relation has important implications for current and future geodetic VLBI programs, as well as the alignment between the radio and optical celestial reference frames.

It is shown that even though the collision of supersolitons is more complicated than in the case of supersymmetric KdV of Manin-Radul, the asymptotic effect of the interaction is simpler. As a physical application it is shown that the well known FPU problem having a phonon-mediated interaction of some internal degrees of freedom expressed through grassmann fields, goes to the Kuper-KdV equation in a multiple-scale approach.

description: Spin glasses are paradigmatic models that deliver concepts relevant for a variety of systems. However, rigorous analytical results are difficult to obtain for spin-glass models, in particular for realistic short-range models. Therefore large-scale numerical simulations are the tool of choice. Concepts and algorithms derived from the study of spin glasses have been applied to diverse fields in computer science and physics. In this work a one-dimensional long-range spin-glass model with power-law interactions is discussed. The model has the advantage over conventional systems in that by tuning the power-law exponent of the interactions the effective space dimension can be changed thus effectively allowing the study of large high-dimensional spin-glass systems to address questions as diverse as the existence of an Almeida-Thouless line, ultrametricity and chaos in short range spin glasses. Furthermore, because the range of interactions can be changed, the model is a formidable test-bed for optimization algorithms.

description: Processing, storing and communicating information that originates as an analog signal involves conversion of this information to bits. This conversion can be described by the combined effect of sampling and quantization, as illustrated in Fig. 1. The digital representation is achieved by first sampling the analog signal so as to represent it by a set of discrete-time samples and then quantizing these samples to a finite number of bits. Traditionally, these two operations are considered separately. The sampler is designed to minimize information loss due to sampling based on characteristics of the continuous-time input. The quantizer is designed to represent the samples as accurately as possible, subject to a constraint on the number of bits that can be used in the representation. The goal of this article is to revisit this paradigm by illuminating the dependency between these two operations. In particular, we explore the requirements on the sampling system subject to constraints on the available number of bits for storing, communicating or processing the analog information.

description: Using first-principles density functional theory calculations, we investigated the effect of charge doping in a LaNiO$_3$/SrTiO$_3$ superlattice. The detailed analysis based on two different simulation methods for doping clearly shows that the electronic and structural properties change in a systematic way that the orbital polarization ({\it i.e.} relative occupation of two Ni-$e_g$ orbitals) is reduced and the Ni to apical oxygen distance enlarged as the number of doped electrons increases. Also, the rotation angles of the NiO$_6$/TiO$_6$ octahedra strongly and systematically depend on the doping so that the angle $γ$ gradually decreases whereas the $α$ and $β$ increase as a function of electron doping. Further analysis shows that the electron (hole) doping can play a similar role with the compressive (tensile) strain for the octahedral rotations. Our results not only suggest a possible way to control the orbital and structural property by means of charge doping, but also provide useful information to understand the experiments under various doping situations such as oxygen vacancy.

For example, quantum objects possess \lq\lq spooky\rq\rq\ properties that allow them to be in multiple places at the same time, to move in different directions simultaneously, or to exist and not to exist. In other words, to live several parallel stories. Making use of these parallel stories to compute is the realm of quantum computation, a world in which information is processed using the laws of quantum physics. Nowadays, quantum computers are an object of an extensive experimental and theoretical research, since it is known that, on paper, these can solve many of the current computational challenges. These are the problems that even the most sophisticated supercomputers of today, or tomorrow, will not be able to solve.

description: The physics that governs quantum monitoring may involve other degrees of freedom than the ones initialised and controlled for probing. In this context we address the simultaneous estimation of phase and dephasing characterizing a dispersive medium, and we explore the role of frequency correlations within a photon pair generated via parametric down-conversion, when used as a probe for the medium. We derive the ultimate quantum limits on the estimation of the two parameters, by calculating the corresponding quantum Cramér-Rao bound; we then consider a feasible estimation scheme, based on the measurement of Stokes operators, and address its absolute performances in terms of the correlation parameters, and, more fundamentally, of the role played by correlations in the simultaneous achievability of the quantum Cramér-Rao bounds for each of the two parameters.

description: This is an introductory text reviewing Lieb-Robinson bounds for open and closed quantum many-body systems. We introduce the Heisenberg picture for time-dependent local Liouvillians and state a Lieb-Robinson bound that gives rise to a maximum speed of propagation of correlations in many body systems of locally interacting spins and fermions. Finally, we discuss a number of important consequences concerning the simulation of time evolution and properties of ground states and stationary states.

Mixed-state certification of quantum capacities for noisy communication channels
Creators: name: Macchiavello, Chiara

Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We extend a recent method to detect lower bounds to the quantum capacity of quantum communication channels by considering realistic scenarios with general input probe states and arbitrary detection procedures at the output. Realistic certification relies on a new bound for the coherent information of a quantum channel that can be applied with arbitrary bipartite mixed input states and generalized output measurements.

description: Operating systems research for many-core systems has recently focused its efforts on supporting the scalability of OS-intensive applications running on increasingly parallel hardware. Lost amidst the march towards this parallel future is efficiency: Perfectly parallel software may saturate the parallel capabilities of the host system, but in doing so can waste hardware resources. This paper describes our motivation for the Vector OS, a design inspired by vector processing systems that provides efficient parallelism. The Vector OS organizes and executes requests for operating system resources through “vector” interfaces that operate on vectors of objects. We argue that these interfaces allow the OS to capitalize on numerous chances to both eliminate redundant work found in OS-intensive systems and use the underlying parallel hardware to its full capability, opportunities that are missed by existing operating systems.
Constrained WZWN Models on G/{S x U(1)^n} and Exchange Algebra of G-Primaries

description: Consistently constrained WZWN models on G/{S x U(1)^n} is given by constraining currents of the WZWN models with G. Poisson brackets are set up on the light-like plane. Using them we show the Virasoro algebra for the energy-momentum tensor of constrained WZWN models. We find a G-primary which satisfies a classical exchange algebra in an arbitrary representation of G. The G-primary and the constrained currents are also shown to obey the conformal transformation with respect to the energy-momentum tensor. It is checked that conformal weight of the constrained currents is 0. This is necessary for the consistency for our formulation of constrained WZWN models.

Identification of a reversible quantum gate: assessing the resources

description: We assess the resources needed to identify a reversible quantum gate among a finite set of alternatives, including in our analysis both deterministic and probabilistic strategies. Among the probabilistic strategies we consider unambiguous gate discrimination, where errors are not tolerated but inconclusive outcomes are allowed, and we prove that parallel strategies are sufficient to unambiguously identify the unknown gate with minimum number of queries. This result is used to provide upper and lower bounds on the query complexity and on the minimum ancilla dimension. In addition, we introduce the notion of generalized t-designs, which includes unitary t-designs and group representations as special cases. For gates forming a generalized t-design we give an explicit expression for the maximum probability of correct gate identification and we prove that there is no gap between the performances of deterministic strategies an those of probabilistic strategies. Hence, evaluating of the query complexity of perfect deterministic discrimination is reduced to the easier problem of evaluating the query complexity of unambiguous discrimination. Finally, we consider discrimination strategies where the use of ancillas is forbidden, providing upper bounds on the number of additional queries needed to make up for the lack of entanglement with the ancillas.

description: The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) [1] provides a rich resource for obtaining an understanding of the galaxies populating the local Universe. Characterizing the large-scale clustering distribution is important for theoretical studies of structure formation. 2MASS offers an all-sky view at two microns, unbiased by young stellar light and minimally affected by dust. We use 2MASS to measure the clustering dipole in the Ks band and compare this to the velocity of the Local Group as measured by the CMB dipole [2]. We also measure the angular correlation function and from this infer the K-band three dimensional power spectrum [3].
Two classes of finite groups whose Chermak-Delgado lattice is a chain of length zero

description: It is an open question in the study of Chermak-Delgado lattices precisely which finite groups $G$ have the property that $CD(G)$ is a chain of length $0$. In this note, we determine two classes of groups with this property. We prove that if $G=AB$ is a finite group, where $A$ and $B$ are abelian subgroups of relatively prime orders with $A$ normal in $G$, then the Chermak-Delgado lattice of $G$ equals $\{AC_B(A)\}$, a strengthening of earlier known results.

description: Many ICT initiatives that attempt to connect end-users to each other rely on Internet-connected PCs using graphical user interfaces (GUIs). While speech-based systems over the telephone have mushroomed in the West in the past decade, their potential remains largely untapped for use in the developing world. We present reasons why speech systems may be preferable to traditional PC/GUI systems in these circumstances, along with the needs such systems can fulfill.
Electromagnetic field effects on $Υ$-meson dissociation in PbPb collisions at LHC energies

description: We investigate the effect of the electromagnetic field generated in relativistic heavy-ion collisions on the dissociation of $Υ$ mesons. The electromagnetic field is calculated using a simple model which characterizes the emerging quark-gluon plasma (QGP) by its conductivity only. A numerical estimate of the field strength experienced by $Υ$ mesons embedded in the expanding QGP and its consequences on the $Υ$ dissociation is made. The electromagnetic field effects prove to be negligible compared to the established strong-interaction suppression mechanisms.

Insulator-metal transition on the triangular lattice

description: Mott insulators with a half-filled band of electrons on the triangular lattice have been recently studied in a variety of organic compounds. All of these compounds undergo transitions to metallic/superconducting states under moderate hydrostatic pressure. We describe the Mott insulator using its hypothetical proximity to a Z_2 spin liquid of bosonic spinons. This spin liquid has quantum phase transitions to descendant confining states with Neel or valence bond solid order, and the insulator can be on either side of one of these transitions. We present a theory of fermionic charged excitations in these states, and describe the route to metallic states with Fermi surfaces. We argue that an excitonic condensate can form near this insulator-metal transition, due to the formation of charge neutral pairs of charge +e and charge -e fermions. This condensate breaks the lattice space group symmetry, and we propose its onset as an explanation of a low temperature anomaly in kappa-(ET)2Cu2(CN)3. We also describe the separate BCS instability of the metallic states to the pairing of like-charge fermions and the onset of superconductivity.
