Subjects: classificationCode: 300999
subject: Veterinary sciences not elsewhere classified

description: Clients typically turn to their local veterinary practice as the first point of call when they are concerned about their pet's behaviour, unless they think it is purely a training problem. Therefore, it is essential that the whole veterinary team are aware of the medical considerations that can affect behaviour (including routine training). Many cases involve medical aspects which should be addressed as part of a multimodal approach to problem behaviour management, which may be the most efficient and effective way to support these cases.This article outlines the medical considerations that should be made in first-opinion practice when presented with a behaviour case in cats and dogs. It also discusses the role of the first-opinion vet in case management and how good collaboration between the vet, a behavioural specialist and the pet owner can aid successful resolution.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Kaluza-Klein (KK) gravitons emission rates due to plasmon-graviton conversion in magnetic field are computed within the ADD model of TeV-scale gravity. Plasma is described in the kinetic approach as the system of charged particles and Maxwell field both confined on the brane. Interaction with multidimensional gravity living in the bulk with $n$ compact extra dimensions is introduced within the linearized theory. Plasma collective effects enter through the two-point correlation function of the fluctuations of the energy-momentum tensor. The estimate for magnetic stars is presented leading to the lower limit of the D-dimensional Plank mass.

description: We describe a new method to determine the position of the atomic cloud during its interaction with the microwave field in the cavity of a fountain clock. The positional information is extracted from the spectrum of the F=3,mF=0 to F=4,mF=-1 hyperfine transition, which shows a position dependent asymmetry when the magnetic C-field is tilted by a few degrees with respect to the cavity axis. Analysis of this spectral asymmetry provides the horizontal center-of-mass position for the ensemble of atoms contributing to frequency measurements. With an uncertainty on the order of 0.1 mm, the obtained information is useful for putting limits on the systematic uncertainty due to distributed cavity phase gradients. The validity of the new method is demonstrated through experimental evidence.

description: The non-orthogonality of algebraic polynomials of field coordinates traditionally used to model field-dependent corrections to astrometric measurements, gives rise to subtle adverse effects. In particular, certain field dependent perturbations in the observational data propagate into the adjusted coefficients with considerable magnification. We explain how the worst perturbation, resulting in the largest solution error, can be computed for a given non-orthogonal distortion model. An algebraic distortion model of full rank can be converted into a fully orthonormal model based on the Zernike polynomials for a circular field of view, or a basis of functions constructed from the original model by a variant of the Gram-Schmidt orthogonalization process for a rectangular field of view. The relative significance of orthonormal distortion terms is assessed simply by the numerical values of the corresponding coefficients. Orthonormal distortion models are easily extendable when the distribution of residuals indicate the presence of higher order terms.

description: The literature on Canadian political culture is sparse and unsatisfactory. None of the work done in this field identifies the components of political culture and as a result, no one has examined the subject in a holistic manner. There are two distinct streams in the literature on Canadian political culture, the qualitative and the quantitative, and these have developed in parallel lines with no attempt to synthesize findings. Recent literature based on survey material reaches conclusions which are based on slim evidence. This thesis is an attempt to construct a model of political culture based on four components. These are values/attitudes, political institutions, myths/symbols and political socialization. These components encompass the entire realm of political culture, covering all the important elements isolated by scholars in this field. As Canada's political culture is said to be fragmented on provincial lines partly as a result of the federal system, it was felt that it should be measured against the political culture of another federal state. The United States was chosen as a model for it has a federal form of government as well as an integrated political culture. As a result of the investigation, it was found that Canada's political culture is fragmented in that the four components do not mesh. However, it was also found that there is little evidence of fragmentation along provincial lines. In other words, there is some evidence that Canada possess the rudiments of a nation political culture. There are some weak links, but nevertheless, there is a core of values and attitudes that is subscribed to from sea to sea.

description: We present a reformulation of the Quantum Query Model (QQM) without considering the measurement step. Our new formulation is described by a set of vectors satisfying some properties, which we call a Block Set. Given an algorithm in QQM we prove that there is an equivalent algorithm in the Block Set Formulation (BSF). If we keep the same measurement step, then we prove that both formulations have the same Gram Matrix of the output states, and the BSF allows us to describe it explicitly. Finally, we test the advantages of BSF by applying this approach to the construction of quantum exact algorithms.

Optimal discrimination of quantum states with a fixed rate of inconclusive outcomes

description: In this paper we present the solution to the problem of optimally discriminating among quantum states, i.e., identifying the states with maximum probability of success when a certain fixed rate of inconclusive answers is allowed. By varying the inconclusive rate, the scheme optimally interpolates between Unambiguous and Minimum Error discrimination, the two standard approaches to quantum state discrimination. We introduce a very general method that enables us to obtain the solution in a wide range of cases and give a complete characterization of the minimum discrimination error as a function of the rate of inconclusive answers. A critical value of this rate is identified that coincides with the minimum failure probability in the cases where unambiguous discrimination is possible and provides a natural generalization of it when states cannot be unambiguously discriminated. The method is illustrated on two explicit examples: discrimination of two pure states with arbitrary prior probabilities and discrimination of trine states.

description: Charles Dickens kam früh mit dem Gesetz in Berührung, als sein Vater wegen Überschuldung inhaftiert wurde. Wie zahlreiche Waisenkinder musste der Zwölfjährige lernen, sich auf der Straße durchzuschlagen. Aus dieser Erfahrung erwuchs ein lebenslanges Interesse an Rechtsfragen, verbunden mit einem tiefen Ressentiment gegenüber den Institutionen der Justiz. Fast alle literarischen Werke von Dickens beziehen sich auf Rechtsfragen, Aspekte des Justizsystems oder der Equity-Rechtsprechung und immer wieder auch auf Gesetzgebungen seiner Zeit. Die Darstellung von Vertretern der Juristenzunft in Dickens' Romanen ist merklich geprägt von dem Bestreben, eine Identifikation mit dieser Sphäre zu vermeiden. Aufgrund seiner anhaltenden und äußerst komplexen Auseinandersetzung mit dem Recht seiner Zeit gilt Dickens als zentraler Autor für die Diskussion der Wechselwirkungen zwischen Recht und Literatur. Dank des Reichtums seiner literarischen Darstellungen dürfte seine Bedeutung für Recht und Literatur auch in Zukunft kaum nachlassen.
description: Brought into contact with the law at the early age of 12, when his father was imprisoned for debt, forcing him to earn a living as another of thousands of orphans and street children, Dickens nourished a lifelong interest in, but also contempt of the law. Accordingly, almost all of his major works show a great concern for legal issues, the justice system, questions of equity and new motions and statutes passed during his career. The treatment of legal representatives in almost all of his novels certainly suggests an eager desire not to identify with this particular sphere. However, Dickens’s long-standing and deeply complex engagement with the laws of his time also makes him one of the most important writers for the law and literature discipline and the richness of his literary representations does not suggest that he will ever be a less significant figure for law and literature.

Its chaotic dynamics is being reported for the first time which has been captured by an electronic circuit. Polyvinylidene fluoride-co-hexafluoropropene (PVdF-HFP) gel electrolyte comprising of a combination of plasticizers (ethylene carbonate and propylene carbonate) and salts have been prepared to study the exchange of ions through porous poly ethylene terephthalate (PET) membranes. The nonlinearity of this system is due to the ion exchange of the polymer gel electrolytes (PGEs) through a porous membrane. The different regimes of spiking and non-spiking chaotic motions are being presented. The possible applications are highlighted.

description: We propose a new method to immunize populations or computer networks against epidemics which is more efficient than any method considered before. The novelty of our method resides in the way of determining the immunization targets. First we identify those individuals or computers that contribute the least to the disease spreading measured through their contribution to the size of the largest connected cluster in the social or a computer network. The immunization process follows the list of identified individuals or computers in inverse order, immunizing first those which are most relevant for the epidemic spreading. We have applied our immunization strategy to several model networks and two real networks, the Internet and the collaboration network of high energy physicists. We find that our new immunization strategy is in the case of model networks up to 14%, and for real networks up to 33% more efficient than immunizing dynamically the most connected nodes in a network. Our strategy is also numerically efficient and can therefore be applied to large systems.

The descriptions and general specifications outlined here have to be read in context with: D2.1: Requirements on grid infrastructure - describing systemic requirements for DC and hybrid Alternating Current and Direct Current (ACDC) grid installations with derived Key Performance Indicators (KPI)s to assess the grid quality; D2.2: Use case specification - a collection of use cases for the pilot installations in HYPERRIDE and relevant technologies such as Information and Communications Technology (ICT) solutions and components (converters, breakers, measurement units). While some solutions for DC grid installations can be directly transferred from AC to DC, it is necessary that novel solutions are developed in many areas from the overall system to individual components. The areas where HYPERRIDE will provide and showcase them at the demonstration sites are: Grid planning and simulation; Grid automation methods; Protection methodologies; Safety and security; Meteorology; Converter technologies; Test and validation methods. For each individual development a start and end Technology Readiness Level (TRL) description is indicated including the development path in subsequent work packages and a general specification based on the current state of knowledge.

description: We present the in-plane optical reflectance measurement on single crystals of URu$_2$As$_2$. The study revealed a strong temperature-dependent spectral evolution. Above 50 K, the low frequency optical conductivity is rather flat without a clear Drude-like response, indicating a very short transport life time of the free carriers. Well below the coherence temperature, there appears an abrupt spectral weight suppression below 400 cm$^{-1}$, yielding evidence for the formation of a hybridization energy gap arising from the mixing of the conduction electron and narrow f-electron bands. A small part of the suppressed spectral weight was transferred to the low frequency side, leading to a narrow Drude component, while the majority of the suppressed spectral weight was transferred to the high frequency side centered near 4000 cm$^{-1}$. Below the hidden order temperature, another very prominent energy gap structure was observed, which leads to the removal of a large part of the Drude component and a sharp reduction of the carrier scattering rate. The study revealed that the hybridization gap and the hidden orger gap are distinctly different: they occur at different energy scales and exhibit completely different spectral characteristics.

We show that our model satisfies two criteria as a model of M-theory. First, we show that the model possesses N=1 supersymmetry in eleven dimensions. Second, we show the model reduces to BFSS matrix theory with finite size matrices in a DLCQ limit.

This corresponds to the equilibrium regime and, therefore, the interaction can be additionally controlled by an electric current. The exchange interaction is long ranged and oscillates as a function of the distance between the walls. It also depends oscillatory on the polarization angle of the walls, having the maximum value for collinear polarization.

description: Rotational mixing in massive main sequence stars is predicted to monotonically increase their surface nitrogen abundance with time. We use this effect to design a method for constraining the age and the inclination angle of massive main sequence stars, given their observed luminosity, effective temperature, projected rotational velocity and surface nitrogen abundance. This method relies on stellar evolution models for different metallicities, masses and rotation rates. We use the population synthesis code STARMAKER to show the range of applicability of our method. We apply this method to 79 early B-type main sequence stars near the LMC clusters NGC 2004 and N 11 and the SMC clusters NGC 330 and NGC 346. From all stars within the sample, 17 were found to be suitable for an age analysis. For ten of them, which are rapidly rotating stars without a strong nitrogen enhancement, it has been previously concluded that they did not evolve as rotationally mixed single stars. This is confirmed by our analysis, which flags the age of these objects as highly discrepant with their isochrone ages. For the other seven stars, their nitrogen and isochrone ages are found to agree within error bars, what validates our method. Constraints on the inclination angle have been derived for the other 62 stars,with the implication that the nitrogen abundances of the SMC stars, for which mostly only upper limits are known, fall on average significantly below those limits. Nitrogen chronology is found to be a new useful tool for testing stellar evolution and to constrain fundamental properties of massive main sequence stars. A web version of this tool is provided.

description: Controlled vocabularies are used to describe knowledge within a particular domain, encompassing a comprehensive collection of domain specific terms. Using controlled vocabularies not only mitigates the challenge of data ambiguity, but also offers several advantages, including references to term definitions, particularly within Metadata Schemas. Additionally, they foster semantic interoperability and facilitate the seamless integration of ontologies. EVOKS, the Editor for Vocabularies to Know Semantics, is a general-purpose vocabulary service which allows data stewards and scientists to easily create or import, edit, curate and publish controlled vocabularies using the W3C recommended SKOS data model [1]. Access to published vocabularies is effectively ensured through the implementation of SKOSMOS [2] as dedicated vocabulary browser instance. We provide a publicly accessible SKOSMOS instance for NFDI-MatWerk [3]. There, it is possible to publish vocabularies created in the NFDI-MatWerk. Additionally, members of NFDI-MatWerk have access to an exemplary EVOKS instance for editing vocabularies [4]. Taking the MatWerk Acronyms Vocabulary [5] as an example, the poster shows basic usage and benefits of using EVOKS. In particular: • Creating and editing of controlled vocabularies • Collaboratively working on vocabularies • Advantages of applying persistent URLs to the vocabulary and vocabulary terms The NFDI-MatWerk Acronyms Vocabulary consists of roughly 70 terms and required approximately two working days to be created. As an application use case, the poster also demonstrates the integration of controlled vocabularies into metadata schemas. Specifically, it illustrates how the narrower concepts of a term from a controlled vocabulary appear as selectable options in the schema's drop-down menu, when a metadata editor interface is configured. The EVOKS interface is designed to be very intuitive and user-friendly: users can quickly familiarise themselves with the platform and navigate its features without significant time investment.

description: Let $A$ be a finite dimensional hereditary algebra over an algebraically closed field $k$, $T_2(A)=(\begin{array}{cc}A&0 A&A\end{array})$ be the triangular matrix algebra and $A^{(1)}=(\begin{array}{cc}A&0 DA&A\end{array})$ be the duplicated algebra of $A$ respectively. We prove that ${\rm rep.dim}\ T_2(A)$ is at most three if $A$ is Dynkin type and ${\rm rep.dim}\ T_2(A)$ is at most four if $A$ is not Dynkin type. Let $T$ be a tilting A-$\module$ and $\ol{T}=T\oplus\ol{P}$ be a tilting $A^{(1)}$-$\module$. We show that $\End_{A^{(1)}} \ol{T}$ is representation finite if and only if the full subcategory $\{(X,Y,f)\ |\ X\in {\rm mod}\ A, Y\inτ^{-1}\mathscr{F}(T_A)\cup{\rm add}\ A\}$ of ${\rm mod \ T_2(A)}$ is of finite type, where $τ$ is the Auslander-Reiten translation and $\mathscr{F}(T_A)$ is the torsion-free class of ${\rm mod}\ A$ associated with $T$. Moreover, we also prove that ${\rm rep.dim\ End}_{A^{(1)}}\ {\ol T}$ is at most three if $A$ is Dynkin type.

description: Glial-cell line derived neurotrophic factor (GDNF) bound to its co-receptor GFRα1 stimulates the RET receptor tyrosine kinase, promoting neuronal survival and neuroprotection. The GDNF-GFRα1 complex also supports synaptic cell adhesion independently of RET. Here, we describe the structure of a decameric GDNF-GFRα1 assembly determined by crystallography and electron microscopy, revealing two GFRα1 pentamers bridged by five GDNF dimers. We reconsitituted the assembly between adhering liposomes and used cryo-electron tomography to visualize how the complex fulfils its membrane adhesion function. The GFRα1:GFRα1 pentameric interface was further validated both in vitro by native PAGE and in cellulo by cell-clustering and dendritic spine assays. Finally, we provide biochemical and cell-based evidence that RET and heparan sulfate cooperate to prevent assembly of the adhesion complex by competing for the adhesion interface. Our results provide a mechanistic framework to understand GDNF-driven cell adhesion, its relationship to trophic signalling, and the central role played by GFRα1.

description: This report documents the second year of the Aleutian Islands Cooperative acoustic study (AICASS). The AICASS was developed to investigate the possibility of conducting scientific acoustic surveys in cooperation with commercial fishermen aboard commercial fishing vessels and use these data to manage the Aleutian Islands walleye pollock (Gadus chalcogrammus) fishery at spatial and temporal scales important to predators such as the Steller sea lion (Eumetopias jubatus). In 2007 the study successfully completed two acoustic surveys and collected biological and oceanographic data important to calculating pollock biomass estimates. The 2007 AICASS demonstrated that it is possible to conduct scientific quality acoustic surveys in the Aleutian Islands aboard properly calibrated and verified commercial fishing vessels equipped with commercially available echosounders.

description: The dependence of the luminosity function of cluster galaxies on the evolutionary state of the parent cluster is still an open issue, in particular as concern the formation/evolution of the brightest cluster galaxies. We plan to study the bright part of the LFs of a sample of very unrelaxed clusters ("DARC" clusters showing evidence of major, recent mergers) and compare them to a reference sample of relaxed clusters spanning a comparable mass and redshift range. Our analysis is based on the SDSS DR7 photometric data of ten, massive, and X-ray luminous clusters (0.2

The influence of fallback discs on the spectral and timing properties of neutron stars

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

description: Fallback discs around neutron stars (NSs) are believed to be an expected outcome of supernova explosions. Here we investigate the consequences of such a common outcome for the timing and spectral properties of the associated NS population, using Monte Carlo population synthesis models. We find that the long-term torque exerted by the fallback disc can substantially influence the late-time period distribution, but with quantitative differences which depend on whether the initial spin distribution is dominated by slow or fast pulsars. For the latter, a single-peaked initial spin distribution becomes bimodal at later times. Timing ages tend to underestimate the real age of older pulsars, and overestimate the age of younger ones. Braking indices cluster in the range 1.5

description: Scientists from the United States and Canada collaborated on aerial surveys for North Atlantic right whales (Eubalaena glacialis) along the Scotian Shelf and in the Gulf of St. Lawrence during the summer of 2015. Contributors included researchers from the National Oceanic and Atmospheric Administration (NOAA), Fisheries and Oceans Canada (DFO), Dalhousie University, the Canadian Whale Institute, and the New England Aquarium. The surveys were directed over bathymetric features potentially attractive to right whales and areas being monitored by passive acoustic gliders. The survey platform was a de Havilland Twin Otter (DHC-6). Two observers scanned the ocean surface for right whales while flying at 230m and 100 knots. Sighting locations of all whales, dolphins, basking sharks, and sea turtles were recorded along with sighting conditions including Beaufort sea state, visibility, and glare.

Recombinant protein production-associated metabolic burden reflects anabolic constraints and reveals similarities to a carbon overfeeding response

description: A comparison of the metabolic response of Escherichia coli BL21 (DE3) towards the production of human basic fibroblast growth factor (hFGF-2) or towards carbon overfeeding revealed similarities which point to constraints in anabolic pathways. Contrary to expectations, neither energy generation (e.g., ATP) nor provision of precursor molecules for nucleotides (e.g., uracil) and amino acids (e.g., pyruvate, glutamate) limit host cell and plasmid-encoded functions. Growth inhibition is assumed to occur when hampered anabolic capacities do not match with the ongoing and overwhelming carbon catabolism. Excessive carbon uptake leads to by-product secretion, for example, pyruvate, acetate, glutamate, and energy spillage, for example, accumulation and degradation of adenine nucleotides with concomitant accumulation of extracellular hypoxanthine. The cellular response towards compromised anabolic capacities involves downregulation of cAMP formation, presumably responsible for subsequently better-controlled glucose uptake and resultant accumulation of glucose in the culture medium. Growth inhibition is neglectable under conditions of reduced carbon availability when hampered anabolic capacities also match with catabolic carbon processing. The growth inhibitory effect with accompanying energy spillage, respectively, hypoxanthine secretion and cessation of cAMP formation is not unique to the production of hFGF-2 but observed during the production of other proteins and also during overexpression of genes without transcript translation.
