description: This paper presents the results of research on the specialization and competitiveness of crop production in European Union countries. The Esteban-Marquillas method of competitiveness changes was used for the research. This method indicates specialized countries and the nature of structural changes in the scope of crop production. The research was carried out on the basis of data on the size of crop production. All data was taken from the databases of the Central Statistical Office. The research covers the years 2005-2016. The obtained results distinguish (inseparable) groups of countries specializing in the production of particular cereal species. The following countries specialize in the production of wheat: Poland, Germany, the Czech Republic, Slovakia, Italy, Lithuania, Latvia, Estonia, Finland, Sweden and Austria; production of barley wheat: Finland, Great Britain, Germany, Italy and Greece; and rye: Portugal, Spain, France, Great Britain, Romania, Hungary, Slovakia. / Synopsis.

description: We report here the first chiral barbiturate to act as a single-component LMOG capable of gelating a variety of chlorinated and aromatic solvents. Solution-based DOSY NMR experiments, solid-state VP-SEM, and X-ray crystallography techniques were used to characterize chloroform-based gels at a variety of size domains. This scaffold provides a simple system to study the dynamics of gelation and self-assembly.

Geodesic Folding of Tetrahedron

description: In this work, we show the geometric properties of a family of polyhedra obtained by folding a regular tetrahedron along regular triangular grids. Each polyhedron is identified by a pair of nonnegative integers. The polyhedron can be cut along a geodesic strip of triangles to be decomposed and unfolded into one or multiple bands (homeomorphic to a cylinder). The number of bands is the greatest common divisor of the two numbers. By a proper choice of pairs of numbers, we can create a common triangular band that folds into different multiple polyhedra that belongs to the family.
WX Cen (= WR 48c) - a possible type Ia Supernova progenitor

description: We confirm the orbital period of WX Cen (WR 48c) determined by Diaz & Steiner (1995) and refined its value to P = 0.416 961 5 d. The light curve of this object has an amplitude of 0.32 magnitudes and has a V-shaped narrow minimum, similar to the ones seen in V Sge, V617 Sgr and in Compact Binary Supersoft Sources - CBSS. The He II Pickering series decrement shows that the system has significant amount of hydrogen. The He II 4686 emission lines became weaker between the 1991 and 2000/2002 observations, indicating distinct levels of activity. The Balmer lines show variable features with V = -2900 km/s in absorption and with V = +/- 3500 km/s in emission. These highly variable events remind the satellites in emission of CBSS. We estimate the color excess as E(B-V)=0.63. Given the distance-color excess relation in the direction of WX Cen, this implies a distance of 2.8 kpc. Interstellar absorption of the Na I D lines show components at -4.1 km/s, which corresponds to the velocity of the Coalsack, and three other components a -23.9, -32.0 and -39.0 km/s. These components are also seen with similar strengths in field stars that have distances between 1.8 and 2.7 kpc. The intrinsic color of WX Cen is (B-V)0=-0.2 and the absolute magnitude, Mv = -0.5. Extended red wings in the strong emission lines are seen. A possible explanation is that the system has a spill-over stream similar to what is seen in V617 Sgr. We predict that when observed in opposite orbital phase, blue wings would be observed. The velocity of the satellite-like feature is consistent with the idea that the central star is a white dwarf with a mass of M ~ 0.9 Msun. With the high accretion rate under consideration, the star may become a SN Ia in a time-scale of 5 X 10^6 years.

description: Coordinatively unsaturated dithiophosphato complex [Cd((MeO)2PS2)2] (1) was reacted with the bifunctional ligands 3,5-di-(4-pyridyl)-1,2,4-thiadiazole (L1) and 3,5-di-(3-pyridyl)-1,2,4-thiadiazole (L2) to give the helicoidal coordination polymer (1·L1)∞ and the paddle-wheel dimer (1·L2)2, both characterised by single-crystal X-ray diffraction. A comparison of the structures with the different supramolecular constructs obtained by reacting L1 and L2 with differently P-substituted dithiophosphoric NiII complexes allowed to evaluate the role of the metal ion for the predictable assembly of this class of coordination polymers. Cadmium dithiophosphato complex [Cd((MeO)2PS2)2] (1) was reacted with bis-functional dipyridyl-thiadiazole ligands L1 and L2 to give the helicoidal coordination polymer (1·L1)∞ and the discrete dimeric paddle-wheel (1·L2)2. A comparison of the structures with different supramolecular constructs previously obtained is presented.

description: In this paper, we investigate irregularities in a cylindrical self-gravitating system which contains the properties of an imperfect matter and electromagnetic field. For $f(R,T,Q)$ theory, in which $R$ represents the Ricci scalar and $T$ shows the trace of matter stress-energy tensor while $Q\equiv R_{γδ}T^{γδ}$, the field equations containing electric charge, mass functions and Darmois junction conditions at the hypersurface are examined. We have adopted new definition of complexity introduced by Herrera \cite{herrera2018new}, generalized it for the static charged cylindrically symmetric case in $f(R,T,Q)$ theory by performing a detailed analysis on the orthogonal splitting of the Riemann curvature tensor. One of the effective scalars, $Y_{TF}$, has been recognized as a complexity factor. This factor is comprised of certain physical components of the fluid such as irregularity in energy density, locally pressure anisotropy and electric charge (arranged in a specific way). In addition, the effects of extra curvature terms of modified gravity are examined by making the relations among the complexity factor, Weyl scalar and Tolman mass.

description: The role of metal salts in inducing supramolecular gel network formation was analysed by reacting two pyridyl-N-oxide amides with various diamagnetic zinc(II) and cadmium(II) salts. Metal induced supramolecular gelation was observed for zinc(II) and cadmium(II) chloride complexes in water and the morphologies of the xerogels were analysed by scanning electron microscopy (SEM). The relative gel strength was corroborated with various non-bonding interactions observed in the solid-state structures of zinc(II) complexes using X-ray diffraction. The non-bonding interactions of the pyridyl-N-oxide amides and the metal complexes were compared to find the key interactions responsible for metallogel formation. The anion induced stimuli-responsive property of the metallogels was studied in the presence of halides and cyanide anions. The cadmium(II) gels were stable in presence of two equivalents of halides but the network collapsed in presence of cyanide anion in water and this property can be used to detect cyanide anions in water.
Smooth and Non-Smooth Dependence of Lyapunov Vectors upon the Angle Variable on a Torus in the Context of Torus-Doubling Transitions in the Quasiperiodically Forced Henon Map

description: A transition from a smooth torus to a chaotic attractor in quasiperiodically forced dissipative systems may occur after a finite number of torus-doubling bifurcations. In this paper we investigate the underlying bifurcational mechanism which seems to be responsible for the termination of the torus-doubling cascades on the routes to chaos in invertible maps under external quasiperiodic forcing. We consider the structure of a vicinity of a smooth attracting invariant curve (torus) in the quasiperiodically forced Henon map and characterize it in terms of Lyapunov vectors, which determine directions of contraction for an element of phase space in a vicinity of the torus. When the dependence of the Lyapunov vectors upon the angle variable on the torus is smooth, regular torus-doubling bifurcation takes place. On the other hand, the onset of non-smooth dependence leads to a new phenomenon terminating the torus-doubling bifurcation line in the parameter space with the torus transforming directly into a strange nonchaotic attractor. We argue that the new phenomenon plays a key role in mechanisms of transition to chaos in quasiperiodically forced invertible dynamical systems.

description: Cooling microwave resonators to near the quantum ground state, crucial for their operation in the quantum regime, is typically achieved by direct device refrigeration to a few tens of millikelvin. However, in quantum experiments that require high operation power such as microwave-to-optics quantum transduction, it is desirable to operate at higher temperatures with non-negligible environmental thermal excitations, where larger cooling power is available. In this Letter, we present a radiative cooling protocol to prepare a superconducting microwave mode near its quantum ground state in spite of warm environment temperatures for the resonator. In this proof-of-concept experiment, the mode occupancy of a 10-GHz superconducting resonator thermally anchored at 1.02~K is reduced to $0.44\pm0.05$ by radiatively coupling to a 70-mK cold load. This radiative cooling scheme allows high-operation-power microwave experiments to work in the quantum regime, and opens possibilities for routing microwave quantum states to elevated temperatures.

(Figs. 81–84)
 As described for Robustagramma binitidum except as follows.
 Body length 1.7 mm. General color dark brown. Gena and lower frons reddish brown; face and antenna brown. Two orbital bristles, anterior orbital bristle small (most head bristles of unique type damaged or lost). Postvertical bristles similar in size to anterior orbital bristle. Postocellar bristles weak. Eye height ca. 2.6 times genal height.
 Acrostichal setulae in 6 or 8 irregular rows between anterior dorsocentral bristles. Posterodorsal katepisternal bristle over half as long as distance between bristle base and wing base. Wing with length ratio of second to third costal sectors ca. 0.56. Discal cell rounded, without appendices. Mid femur of male with two anterior subapical bristles, 7 ventral proximal bristles and one posterodorsal apical bristles.
 Male terminalia: Sternite 5 ca. 1.5 times as long as sternite 4, with many dark, clublike scales on posteromedial margin, two patches of short, stout bristles on central area, and a borderline between pale posterocentral area and dark anterior area; without shining patches. Dorsomedial length of epandrium ca. 0.25X length of sternite 8. Surstylus entirely setose; cerci cuneate, shorter than surstylus. Ejaculatory apodeme small.
Holotype (♂, DEBU): VENEZUELA: Bolívar, km 40 Sta. Elena­Icabaru Road, 1000m, 4–6.viii.1986, B. Gill.
 Etymology: The specific epithet refers to the apparent rarity of Robustagramma rarum.
 Comments: Robustagramma rarum differs from Robustagramma obscuratum Cui and Marshall, new speciesin surstylar setosity and shape. Two male specimens (labelled: COLUMBIA. Leticia, pepper farm, dung, iii.1974, V. Nealis), with terminalia identical to that of Robustagramma rarum probably belong to this species, but they are distinctly smaller in size (1.35 mm), more yellowish in color, and have smaller eyes (2.1–2.3 times genal height).

description: Digital Twins are digital representations of systems in the Internet of Things (IoT) that are often based on AI models that are trained on data from those systems. Semantic models are used increasingly to link these datasets from different stages of the IoT systems life-cycle together and to automatically configure the AI modelling pipelines. This combination of semantic models with AI pipelines running on external datasets raises unique challenges particular if rolled out at scale. Within this paper we will discuss the unique requirements of applying semantic graphs to automate Digital Twins in different practical use cases. We will introduce the benchmark dataset DTBM that reflects these characteristics and look into the scaling challenges of different knowledge graph technologies. Based on these insights we will propose a reference architecture that is in-use in multiple products in IBM and derive lessons learned for scaling knowledge graphs for configuring AI models for Digital Twins.

On the reliability of the black hole mass and mass to light ratio determinations with Schwarzschild models

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: In this Letter, we investigate the claim of Valluri et al. (2003), namely that the use of Schwarzschild dynamical (orbit-based) models leads to an indeterminacy regarding the estimation of the free parameters like the central black hole mass and the stellar mass-to-light ratio of the galaxy under study. We examine this issue with semi-analytic two-integral models, which are not affected by the intrinsic degeneracy of three-integral systems. We however confirm the Valluri et al. result, and observe the so-called widening of the chi2 contours as the orbit library is expanded. We also show that, although two-dimensional data coverage help in constraining the orbital structure of the modelled galaxy, it does not in principle solve the indeterminacy issue, which mostly originates from the discretization of such an inverse problem. We show that adding regularization constraints stabilizes the confidence level contours on which the estimation of black hole mass and stellar mass-to-light ratio are based. We therefore propose to systematically use regularization as a tool to prevent the solution to depend on the orbit library. Regularization, however, introduces an unavoidable bias on the derived solutions. We hope that the present Letter will trigger some more research directed at a better understanding of the issues addressed here.

description: In an anti-Hermitian linear system, all energy eigenvalues are purely imaginary and the corresponding eigenvectors are orthogonal. This implies that no stationary state is available in such systems. We consider an anti-Hermitian lattice with cubic nonlinearity and explore novel nonlinear stationary modes. We discuss that relative population is conserved in a nonreciprocal tight binding lattice with periodical boundary conditions as opposed to parity-time (PT) symmetric lattices. We study nonlinear nonrecipocal dimer, triple and quadrimer models and construct stationary nonlinear modes.

description: Quantitative structure–property relationship (QSPR) models were developed for predicting the pungency of a set of capsaicinoids. Multiple linear regression (MLR) coupled with topological substructural molecular descriptor (TOPS-MODE) approach was used. The best MLR model based on only five orthogonalized TOPS-MODE variables allowed us to obtain a coefficient of determination of 0.954 on the training set. The predictive power of the model was validated through a test set and several external validation parameters. This showed that the TOPS-MODE descriptors weighted by bond dipole moments, van der Waals atomic radii, and the total solute hydrogen bond basicity affected pungency. The contributions of certain bonds and fragments to pungency were used to understand the pungency mechanism of capsaicinoids. The selected model can more accurately predict pungency of capsaicinoids compared than those found in the literature, and especially bring insights into the structural features and chemical factors related to pungency.

description: We demonstrate that resonant excitation of CdMnTe self-assembled quantum dots creates an ensemble of spin-polarized magnetic polarons at B=0 T. The strong spatial confinement characteristic of quantum dots significantly increases the stability of magnetic polarons so that the optically induced spin alignment is observed for temperatures > 120 K.

description: Stream-reasoning query languages such as CQELS and C-SPARQL enable query answering over RDF streams. Unfortunately, there currently is a lack of efficient RDF stream generators to feed RDF stream reasoners. State-of-the-art RDF stream generators are limited with regard to the velocity and volume of streaming data they can handle. To efficiently generate RDF streams in a scalable way, we extended the RMLStreamer to also generate RDF streams from dynamic heterogeneous data streams. This paper introduces a scalable solution that relies on a dynamic window approach to generate RDF streams with low latency and high throughput from multiple heterogeneous data streams. Our evaluation shows that our solution outperforms the state-of-the-art by achieving millisecond latency (compared to seconds that state-of-the-art solutions need), constant memory usage for all workloads, and sustainable throughput of around 70,000 records/s (compared to 10,000 records/s that state-of-the-art solutions take). This opens up the access to numerous data streams for integration with the semantic web.

A Review of the Impacts of Climate Change on BC's Freshwater Fish Resources and Possible Management Responses
Creators: name: Tyedmers, Peter
name: Ward, Bruce
Publisher: name: Fisheries Centre, University of British Columbia
Year: 2017

description: We review the potential impacts of anthropogenic climate change on BC's freshwater fish and provide a set of recommended management responses that address these potential impacts. The direct impacts are rising temperatures, altered hydrologic regimes, and changes in aquatic productivity. The indirect impacts include the potential loss of estuarine habitat due to sealevel rise, and reduced habitat availability due to increased impoundment and abstraction of water for other uses. These impacts will reinforce or counteract each other to alter the abundance and diversity of fish resources, and will make it difficult for managers to protect, restore, and enhance either the diversity of native freshwater fish or the quality of aquatic habitats. Moreover, as a large proportion of current freshwater recreational angling in the Province is conducted in areas where existing fisheries resources are most likely to be negatively influenced by global warming (i.e. in south central and southeastern regions) it will be difficult to maintain and improve the quality and quantity of recreational angling. We detail the following recommendations: 1. develop climate change scenarios that are locally specific; 2. monitor biophysical indicators of change within freshwater (i.e., monitor changes in thermo-hydrodynamic characteristics of rivers and lakes, expand stock assessment and inventory efforts in habitats of greatest concern, and identify and monitor biological indicators of climate change); 3. develop models of the distribution of freshwater fish in BC and anticipated changes; and, 4. adopt management strategies now that will reduce the impact of climate change on individual species, ecosystems, and society. We conclude that climate change will dramatically alter the abundance, distribution and utilization of many, if not all, species of freshwater fish in the Province. It is essential that in fisheries strategic plans, the challenges posed by climate change are explicitly addressed, and management responses incorporated.
Improved efficiency of stimulated Raman adiabatic passage in photoassociation of a Bose-Einstein condensate

description: We theoretically examine Raman photoassociation of a Bose-Einstein condensate, revisiting stimulated Raman adiabatic passage (STIRAP). Due to collisional mean-field shifts, efficient molecular conversion requires strong coupling and low density, either of which can bring about rogue photodissociation to noncondensate modes. We demonstrate explicitly that rogue transitions are negligible for low excited-state fractions and photodissociation that is slower than the STIRAP timescale. Moreover, we derive a reduced-parameter model of collisions, and thereby find that a gain in the molecular conversion efficiency can be obtained by adjusting the atom-atom scattering length with off-resonant magnetoassociation. This gain saturates when the atom-atom scattering length is tuned to a specific fraction of either the molecule-molecule or atom-molecule scattering length. We conclude that a fully-optimized STIRAP scheme may offer the best chance for achieving coherent conversion from an atomic to a molecular condensate with photoassociation.

description: The evaluation of persistency of chemicals in environmental media (water, soil, sediment) is included in European Regulations, in the context of the Persistence, Bioaccumulation and Toxicity (PBT) assessment. In silico predictions are valuable alternatives for compounds screening and prioritization. However, already existing prediction tools have limitations: narrow applicability domains due to their relatively small training sets, and lack of medium-specific models. A dataset of 1579 unique compounds has been collected, merging several persistence data sources annotated by, at least, one experimental dissipation half-life value for the given environmental medium. This dataset was used to train binary classification models discriminating persistent/non-persistent (P/nP) compounds based on REACH half-life thresholds on sediment, water and soil compartments. Models were built using ISIDA (In SIlico design and Data Analysis) fragment descriptors and support vector regression, random forest and naïve Bayesian machine-learning methods. All models scored satisfactory performances: sediment being the most performing one (BAext = 0.91), followed by water (BAext = 0.77) and soil (BAext = 0.76). The latter suffer from low detection of persistent (‘P’) compounds (Snext = 0.50), reflecting discrepancies in reported half-life measurements among the different data sources. Generated models and collected data are made publicly available.
An exact effective two-qubit gate in a chain of three spins

description: We show that an effective two-qubit gate can be obtained from the free evolution of three spins in a chain with nearest neighbor XY coupling, without local manipulations. This gate acts on the two remote spins and leaves the mediating spin unchanged. It can be used to perfectly transfer an arbitrary quantum state from the first spin to the last spin or to simultaneously communicate one classical bit in each direction. One ebit can be generated in half of the time for state transfer. For longer spin chains, we present methods to create or transfer entanglement between the two end spins in half of the time required for quantum state transfer, given tunable coupling strength and local magnetic field. We also examine imperfect state transfer through a homogeneous XY chain.
