AT2OA

description: Presentation at the Open Access Tage Graz 26th September 2018 Im Rahmen des österreichischen HRSM Projekts „Austrian Transition to Open Access“ (AT2OA) wurde ein Teilprojekt gestartet, welches sich mit Budget- und Kostenfragen eines weiteren Ausbaus von Open Access beschäftigt. In einer ersten Studie wurde der Frage nachgegangen, ob ein weiterer Ausbau von Open Access in den nächsten Jahren budgetäre Konsequenzen hat. Im Rahmen dieser Transition-Studie zu diesem Themenkomplex wurden 1) der Publikationsoutput Österreichs aufbereitet und für die Zwecke des Projekts analysiert. Diese Daten wurden in mehreren Bereichen des Projekts für Berechnungen herangezogen. Anhand der Publikationsoutput-Analyse wurden 2) Methoden entwickelt, verschiedene Ausbaustufen für einen institutionellen Publikationsfonds zu berechnen. Des weiteren wurden 3) mit der Szenario-Technik verschiedene mögliche Entwicklungen der Konsortialverträge mit Open Access-Komponenten prognostiziert. Kostenübernahmen durch Fördergeber wurden 4) exemplarisch anhand aktueller Daten des FWF in die Analysen mit einbezogen. Diese Daten wurden auch für repräsentative Berechnung von Durchschnitts-APCs herangezogen. Und 5) wurden die verschiedenen AT2OA-Förderungen zum Ausbau von Open Access in Österreich zusammenfassend dargestellt. In dem Beitrag werden die verschiedenen entwickelten Methoden und Ergebnisse dargestellt und kritisch diskutiert.

description: Dynamic fracture in a wide class of materials reveals "fracture energy" $Γ$ much larger than the expected nominal surface energy due to the formation of two fresh surfaces. Moreover, the fracture energy depends on the crack velocity, $Γ=Γ(v)$. We show that a simple dynamical theory of visco-plasticity coupled to asymptotic pure linear-elasticity provides a possible explanation to the above phenomena. The theory predicts tip blunting characterized by a dynamically determined crack tip radius of curvature. In addition, we demonstrate velocity selection for cracks in fixed-grip strip geometry accompanied by the identification of $Γ$ and its velocity dependence.

description: This deliverable (DL) provides an introduction to fish welfare in aquaculture and results from the systematization of knowledge for sea bass and sea bream, evaluating risk factors and welfare indicators. A comparison of the main certification schemes and standards production and good practices used in SBB and SBG companies is further assessed with respect to health and welfare principles and indicators applied. The DL reports on the process of selection and validation of OWIs by the PerformFISH Consortium. The methodology to assess and score fish welfare at different life stage and farming system is provided. A first benchmarking of welfare status of farmed bass and bream for MMFF is given based on OWIs data collection on farm and from PerformFISH Gateway D4Science(W-KPIs from WP7). Most part of the work is completed and the list of OWIs is consolidated (task 3.5.1, 3.5.2). However, due to the Covid-19 pandemic, activities related to OWIs implementation on farm and elaboration of welfare scoring (task 3.5.3) have been suspended on February 15th. The present DL is thus submitted as a draft version. It is estimated that the DL3.6 will be finalized within 6 months after pandemic restrictions are lifted.
An evaluation of intervention designed to teach communication strategies to care-givers of nursing home residents
Creators: name: Rennert, Karin I.
Publisher: name: University of British Columbia
Year: 2010

description: This study evaluated the ability of nursing home staff to implement communication strategies as a result of inservice education. Seventeen subjects, from two occupational groups (patient care aides, and rehabilitation staff), were observed twice each during routine interactions with the nursing home residents. The measurement tool consisted of 11 communication behaviours, which were scored according to degree of use. There were two categories of strategies: those that could be used in all situations, and those that were appropriate only for some situations. Results were mixed: the experimental group (N=5), who attended the inservice, showed an increase in the use of latter category of communication strategies, while the control group (N=12) decreased their use of the same strategies. In the former category of strategies, no difference was found between the experimental and control groups. The discussion focused on possible sources of confound, and recommendations for further research.

description: The e-commerce share in the global retail spend is showing a steady increase over the years indicating an evident shift of consumer attention from bricks and mortar to clicks in retail sector. In recent years, online marketplaces have become one of the key contributors to this growth. As the business model matures, the number and types of frauds getting reported in the area is also growing on a daily basis. Fraudulent e-commerce buyers and their transactions are being studied in detail and multiple strategies to control and prevent them are discussed. Another area of fraud happening in marketplaces are on the seller side and is called merchant fraud. Goods/services offered and sold at cheap rates, but never shipped is a simple example of this type of fraud. This paper attempts to suggest a framework to detect such fraudulent sellers with the help of machine learning techniques. The model leverages the historic data from the marketplace and detect any possible fraudulent behaviours from sellers and alert to the marketplace.

description: The growth of Hilbert coefficients for powers of ideals are studied. For a graded ideal $I$ in the polynomial ring $S=K[x_1,...,x_n]$ and a finitely generated graded $S$-module, the Hilbert coefficients $e_i(M/I^kM)$ are polynomial functions. Given two families of graded ideals $(I_k)_{k\geq 0}$ and $(J_k)_{k\geq 0}$ with $J_k\subset I_k$ for all $k$ with the property that $J_kJ_\ell\subset J_{k+\ell}$ and $I_kI_\ell\subset I_{k+\ell}$ for all $k$ and $\ell$, and such that the algebras $A=\Dirsum_{k\geq 0}J_k$ and $B=\Dirsum_{k\geq 0}I_k$ are finitely generated, we show the function $k \mapsto_0(I_k/J_k)$ is of quasi-polynomial type, say given by the polynomials $P_0,..., P_{g-1}$. If $J_k = J^k$ for all $k$ then we show that all the $P_i$ have the same degree and the same leading coefficient. As one of the applications it is shown that $\lim_{k\to \infty}\length(Γ_\mm(S/I^k))/k^n \in \mathbb{Q}.$ We also study analogous statements in the local case.

description: To investigate the risk factors affecting the technical failure of artificial ascites (AA) formation and to evaluate the local control efficacy of percutaneous thermal ablation assisted by the AA for hepatic tumors. A total of 341 patients with 362 hepatic tumors who underwent thermal ablation assisted by AA were reviewed retrospectively. The technical success of AA, the volume of liquid, and local efficacy after ablation were assessed. Predictive factors for the technical failure of AA formation and local tumor progression (LTP) were analyzed using univariate and multivariate analysis. The technical success rate of AA formation was 81.8% (296/362). The amount of fluid was higher when the tumor was located in the left lobe of the liver than when it was located in the right lobe (median 950 ml versus 700 ml, p < 0.001). Previous hepatic resection (OR: 12.63, 95% CI: 2.93–54.45, p < 0.001), ablation (OR: 6.48, 95% CI: 1.36–30.92, p = 0.019) and upper-abdomen surgery (OR: 11.34, 95% CI: 1.96–65.67, p = 0.007) were the independent risk factors of AA failure. In the AA success group, the complete ablation rate was higher and the LTP rate was lower than that in the AA failure group (98.7 versus 92.4%, p = 0.012; 8.8 versus 21.2%, p = 0.004). Multivariate analysis identified AA failure (p = 0.004), tumor size (>3.0 cm) (p = 0.002) and metastatic liver tumor (p = 0.008) as independent risk factors for LTP. History of hepatic resection, ablation and upper abdomen surgery were significant predictive factors affecting the technical failure of AA formation. Successful introduction of AA before thermal ablation can achieve better local tumor control efficacy.

description: It has been a hot issue to search for hydrides at high pressure with high superconducting transition temperature (Tc). In this work, ternary hydrogen-rich compounds KYHn (n = 1-16) were studied and calculated using the density function theory (DFT) method and he results showed that the KYH8 demonstrates good stability and superconductivity. And keep thermodynamically stable in the pressure range of 50-300 GPa. The research found that the Tc of KYH8-C2/m was predicted to be 111.3K, 122.0K, and 142.3K at 200, 250 and 300 GPa, respectively. Our current study provides a possibility for searching new high-Tc superconductors in ternary hydrides.

description: Calculations, performed in Thomas-Fermi approximation, show that the energy of a condensed phase of molecular metallic oxygen is lower by 496 kJ/mol than that of an insulator oxygen phase. The insulator phase is separated from a metallic one by energetic barrier of 1165 kJ/mol. This barrier could be overcome by means of electromagnetic irradiation with quantum energy of 12.071 eV or a bit higher. During such a transition the amount of energy equal to 496 kJ/mol is released. It should be extracted from a sample to secure the existence of a metallic phase.

Both types of nanoparticles and ceftriaxone implied modification in different ways to the polymeric material and their strength of bacterial rejection through membrane was also dependent on antibacterial properties ofrespective nanoparticles. Silver fabricated membranes showed much better results as compared to titania. All these results were analyzed statistically and showed significant p-value less 0.00005. Overall study showed nanoparticles and drug fabrication in polymer membranes enhanced its bacterial rejection properties. Silver showed much better results as their particles size was small and in case of bacterial rejection, it is known to be better antimicrobial compared to titania.

The spatial variation of bed material texture in coupled basins on the Queen Charlotte Islands
Creators: name: Rice, Stephen Philip
Publisher: name: University of British Columbia
Year: 2010

description: Whether one is interested in the geomorphology, hydrology, or ecology of a river, the nature of the bed sediments is of major importance. Despite a long history of interest our ability to predict local grain size is poor, which is unfortunate given the labour and costs associated with bed material sampling. A preliminary model of sediment texture variation at the drainage basin scale, which makes a fundamental distinction between coupled and uncoupled hillslope-channel units, is presented. It is hypothesised that grain size variations in strongly coupled rivers are unstructured as a result of overbank colluvial inputs and special storage elements. These preclude the development of the systematic downstream structure commonly associated with fluvial sorting and abrasion processes in uncoupled channels. This conjecture is assessed empirically using data collected in two rivers on the Queen Charlotte Islands. It is found that distance alone does not explain changes in grain size, and that local variations are dominated by large organic debris jams. Impermeable jams are associated with upstream fining and downstream coarsening but the effect diminishes as the jams become more permeable, often with age. Jam placement is random, but frequent, and consequently at the drainage basin scale, grain size changes dramatically and unpredictably over very short distances. No deterministic structure is apparent. Further analysis reveals that the observed variations of surface median grain size and Fredle index are best regarded as stochastic phenomena. Sampling criteria are then determined which enable the accurate characterisation of such variation, once a stream has been classified by land use and position relative to hillslopes.

description: We implement a dynamical resummation method (DRM) as an extension of the dynamical renormalization group to study the time evolution of infrared dressing in non-gauge theories. Super renormalizable and renormalizable models feature infrared divergences similar to those of a theory at a critical point, motivating a renormalization group improvement of the propagator that yields a power law decay of the survival probability $\propto t^{-Δ}$. The (DRM) confirms this decay, yields the dressed state and determines that the anomalous dimension $Δ$ is completely determined by the slope of the spectral density at threshold independent of the ultraviolet behavior, suggesting certain universality for infrared phenomena. The dressed state is an entangled state of the charged and massless quanta. The entanglement entropy is obtained by tracing over the unobserved massless quanta. Its time evolution is determined by the (DRM), it is infrared finite and describes the information flow from the initial single particle to the asymptotic multiparticle dressed state. We show that effective field theories of massless axion-like particles coupled to fermion fields do not feature infrared divergences, and provide a criterion for infrared divergences in effective field theories valid for non-gauge theories up to one loop.

description: We have studied the magneto-optical and magnetotrasnport properties of GaMnAs thin films with high Mn concentrations (x= 12.2 - 21.3%) grown by molecular-beam epitaxy. These heavily Mn-doped GaMnAs films were formed by decreasing the growth temperature to as low as 150-190 degree C and by reducing the film thickness to 10 nm in order to prevent precipitation of hexagonal MnAs clusters. Magnetic circular dichroism (MCD) and anomalous Hall effect measurements indicate that these GaMnAs films have the nature of intrinsic ferromagnetic semiconductors with high ferromagnetic transition temperature up to 170 K.

description: This paper describes an analysis of the NuSTAR data of the fastest-rotating magnetar 1E 1547$-$5408, acquired in 2016 April for a time lapse of 151 ks. The source was detected with a 1-60 keV flux of $1.7 \times 10^{-11}$ ergs s$^{-1}$ cm$^{-2}$, and its pulsation at a period of $2.086710(5)$ sec. In 8-25 keV, the pulses were phase-modulated with a period of $T=36.0 \pm 2.3$ ks, and an amplitude of $\sim 0.2$ sec. This reconfirms the Suzaku discovery of the same effect at $T=36.0 ^{+4.5}_{-2.5} $ ks, made in the 2009 outburst. These results strengthen the view derived from the Suzaku data, that this magnetar performs free precession as a result of its axial deformation by $\sim 0.6 \times 10^{-4}$, possibly caused by internal toroidal magnetic fields reaching $\sim 10^{16}$ G. Like in the Suzaku case, the modulation was not detected in energies below $\sim 8$ keV. Above 10 keV, the pulse-phase behaviour, including the 36 ks modulation parameters, exhibited complex energy dependences: at $\sim 22$ keV, the modulation amplitude increased to $\sim 0.5$ sec, and the modulation phase changed by $\sim 65^\circ$ over 10--27 keV, followed by a phase reversal. Although the pulse significance and pulsed fraction were originally very low in $>10$ keV, they both increased noticeably, when the arrival times of individual photons were corrected for these systematic pulse-phase variations. Possible origins of these complex phenomena are discussed, in terms of several physical processes that are specific to ultra-strong magnetic fields.

One of the most prominent equations is KdV (Kortwege-de Vries) equation with application in shallow water theory. In this paper we are going to explain a particular method for finding symmetries of KdV equation, which is called Harrison method. Our tools in this method are Lie derivatives and differential forms, which will be discussed in the first section more precisely. In second chapter we will have some analysis on the solutions of KdV equation and we give a method, which is called first integral method for finding the solutions of KdV equation.

description: The development of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is driven by chronic inflammatory responses and acquired genetic changes. To investigate its genetic bases, we performed targeted sequencing of 93 genes in 131 MALT lymphomas including 76 from the thyroid. We found frequent deleterious mutations of TET2 (86%), CD274 (53%), TNFRSF14 (53%), and TNFAIP3 (30%) in thyroid MALT lymphoma. CD274 was also frequently deleted, together with mutation seen in 68% of cases. There was a significant association between CD274 mutation/deletion and TNFRSF14 mutation (p = 0.001). CD274 (PD-L1) and TNFRSF14 are ligands for the co-inhibitory receptor PD1 and BTLA on T-helper cells, respectively, their inactivation may free T-cell activities, promoting their help to malignant B-cells. In support of this, both the proportion of activated T-cells (CD4+CD69+/CD4+) within the proximity of malignant B-cells, and the level of transformed blasts were significantly higher in cases with CD274/TNFRSF14 genetic abnormalities than those without these changes. Both CD274 and TNFRSF14 genetic changes were significantly associated with Hashimoto's thyroiditis (p = 0.01, p = 0.04, respectively), and CD274 mutation/deletion additionally associated with increased erythrocyte sedimentation rate (p = 0.0001). In conclusion, CD274/TNFRSF14 inactivation in thyroid MALT lymphoma B-cells may deregulate their interaction with T-cells, promoting co-stimulations and impairing peripheral tolerance.

description: The thesis is a study on classical Arabic phraseology on the basis of prose works by Lisān ad-Dīn Ibn al-Khaṭīb (d. 776/1374). It reinvestigates the linguistic concept of a phraseme from a theoretical perspective and adopts the approach of cultural analysis to a selected corpus of classical Arabic phasemes. The results indicate that classical Arabic phrasemes, whether referential or communicative, have four main source domains: historical references, nature, material culture and habitus, and Islamic religious motivations (with either religious or non-religious target domains). The cultural phenomenon that motivates most of them is cultural modelling, although it does not contribute to their fixedness. Two other cultural phenomena – cultural symbolism and quotation – were found to have the strongest impact on phrasemes’ fixedness levels, albeit with some exceptions.

description: We calculate the spin current distribution function for a Kondo dot in two different regimes. In the exactly solvable Toulouse limit the linear response, zero temperature statistics of the spin transfer is trinomial, such that all the odd moments vanish and the even moments follow a binomial distribution. On the contrary, the corresponding spin-resolved distribution turns out to be binomial. The combined spin and charge statistics is also determined. In particular, we find that in the case of a finite magnetic field or an asymmetric junction the spin and charge measurements become statistically dependent. Furthermore, we analyzed the spin counting statistics of a generic Kondo dot at and around the strong-coupling fixed point (the unitary limit). Comparing these results with the Toulouse limit calculation we determine which features of the latter are generic and which ones are artifacts of the spin symmetry breaking.

description: Kagome metals AV3Sb5 (A = K, Rb, and Cs) exhibit superconductivity at 0.9-2.5 K and charge-density wave (CDW) at 78-103 K. Key electronic states associated with the CDW and superconductivity remain elusive. Here, we investigate low-energy excitations of CsV3Sb5 by angle-resolved photoemission spectroscopy. We found an energy gap of 70-100 meV at the Dirac-crossing points of linearly dispersive bands, pointing to an importance of spin-orbit coupling. We also found a signature of strongly Fermi-surface and momentum-dependent CDW gap characterized by the larger energy gap of maximally 70 meV for a band forming a saddle point around the M point, the smaller (0-18 meV) gap for a band forming massive Dirac cones, and a zero gap at the Gamma-centered electron pocket. The observed highly anisotropic CDW gap which is enhanced around the M point signifies an importance of scattering channel connecting the saddle points, laying foundation for understanding the nature of CDW and superconductivity in AV3Sb5.

description: O trabalho aborda o contexto histórico da educação superior no Brasil, no que diz respeito a sua origem e expansão. Este estudo exploratório-descritivo, utilizando-se da pesquisa bibliográfica e documental para caracterizar o surgimento e a expansão das universidades, contextualizando a origem dessas instituições na Europa, nas Américas e no Brasil, bem como a expansão da oferta de ensino superior no país. Os resultados evidenciam uma inserção extremamente tardia das universidades no país, apesar do histórico de ensino superior desde o Brasil Colônia, bem como um cenário de resistências à criação dessas instituições até o ano de 1920, com a criação da Universidade do Rio de Janeiro. Além disso, nos últimos anos, houve significativa expansão da educação superior, principalmente pela iniciativa privada, a partir do período de Ditadura Militar, sendo bem mais lenta no setor público.

description: Jacques Offenbach’s La belle Hélène (1864) was the successor to Orphée aux Enfers (1858; 1874) in both its send-up of Greek myth and its production triumph. Four other mature and now well-known operettas followed: Barbe-bleue (1866), La Vie parisienne (1866), La Grande-Duchesse de Gérolstein (1867), and La Périchole (1868). All of these—along with La belle Hélène—were composed to libretti by Henri Meilhac and Ludovic Halévy.
Flux domes in superconducting films without edges

description: Domelike magnetic-flux-density distributions previously have been observed experimentally and analyzed theoretically in superconducting films with edges, such as in strips and thin plates. Such flux domes have been explained as arising from a combination of strong geometric barriers and weak bulk pinning. In this paper we predict that, even in films with bulk pinning, flux domes also occur when vortices and antivortices are produced far from the film edges underneath current-carrying wires, coils, or permanent magnets placed above the film. Vortex-antivortex pairs penetrating through the film are generated when the magnetic field parallel to the surface exceeds H_{c1}+K_c, where H_{c1} is the lower critical field and K_c = j_c d is the critical sheet-current density (the product of the bulk critical current density j_c and the film thickness d). The vortices and antivortices move in opposite directions to locations where they join others to create separated vortex and antivortex flux domes. We consider a simple arrangement of a pair of current-carrying wires carrying current I_0 in opposite directions and calculate the magnetic-field and current-density distributions as a function of I_0 both in the bulk-pinning-free case (K_c = 0) and in the presence of bulk pinning, characterized by a field-independent critical sheet-current density (K_c > 0).

description: We study celestial amplitudes in (super) Yang-Mills theory using a parameterisation of the spinor helicity variables where their overall phase is not fixed by the little group action. In this approach the spin constraint $h-\bar{h}=J$ for celestial conformal primaries emerges naturally from a new Mellin transform, and the action of conformal transformations on celestial amplitudes is derived. Applying this approach to $\mathcal{N}\!=\!4$ super Yang-Mills, we show how the appropriate definition of on-shell superspace coordinates leads naturally to a formulation of chiral celestial superamplitudes and a representation of the generators of the four-dimensional superconformal algebra on the celestial sphere, which by construction annihilate all tree-level celestial superamplitudes.

Vorticity structuring and Taylor-like velocity rolls triggered by gradient shear bands

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We suggest a novel mechanism by which vorticity structuring and Taylor-like velocity rolls can form in complex fluids, triggered by the linear instability of one dimensional gradient shear banded flow. We support this with a numerical study of the diffusive Johnson-Segalman model. In the steady vorticity structured state, the thickness of the interface between the bands remains finite in the limit of zero stress diffusivity, presenting a possible challenge to the accepted theory of shear banding.

description: In this paper we prove tight bounds on the combinatorial and topological complexity of sets defined in terms of $n$ definable sets belonging to some fixed definable family of sets in an o-minimal structure. This generalizes the combinatorial parts of similar bounds known in the case of semi-algebraic and semi-Pfaffian sets, and as a result vastly increases the applicability of results on combinatorial and topological complexity of arrangements studied in discrete and computational geometry. As a sample application, we extend a Ramsey-type theorem due to Alon et al., originally proved for semi-algebraic sets of fixed description complexity to this more general setting.

description: Dynamical quantum phase transitions (DQPTs) are topologically characterized in quantum quench dynamics in topological systems. In this paper, we study Loschmidt amplitudes and DQPTs in quantum quenches in mirror-symmetric topological phases. Based on the topological classification of mirror-symmetric insulators, we show that mirror symmetry creates symmetry-protected DQPTs. If mirror symmetry is present, topologically robust DQPTs can occur in quantum quenches, even in high-dimensional time-reversal invariant systems. Then, we also show that symmetry-protected DQPTs occur in quenches in two-dimensional chiral-symmetric systems with mirror symmetry. Mirror-symmetry-protected DQPTs can be easily captured by a reduced rate function. Moreover, we introduce dynamical topological order parameters for mirror-symmetry-protected DQPTs. Finally, we demonstrate DQPTs using lattice models for a time-reversal invariant topological crystalline insulator and a higher-order topological insulator.

description: In the current LambdaCDM cosmological scenario, N-body simulations provide us with a Universal mass profile, and consequently a Universal equilibrium circular velocity of the virialized objects, as galaxies. In this paper we obtain, by combining kinematical data of their inner regions with global observational properties, the Universal Rotation Curve (URC) of disk galaxies and the corresponding mass distribution out to their virial radius. This curve extends the results of Paper I, concerning the inner luminous regions of Sb-Im spirals, out to the edge of the galaxy halos.
