description: Current state-of-the-art simulations of accretion flows onto black holes require a significant level of numerical sophistication, in order to allow the three-dimensional modelling of relativistic magnetised plasma in a regime of strong gravity. We present here a new version of the GRMHD code \texttt{ECHO} developed in collaboration with the Max Planck Computing and Data Facility (MPCDF) and the Leibniz Rechenzentrum (LRZ), which employs a hybrid multidimensional MPI-OpenMP coupled with the production of MPI-HDF5 output files. The code's high degree of parallelisation has been crucial for the study of some fundamental properties of thick accretion disks around black holes, in particular the excitation of non-axisymmetric modes in presence of both hydrodynamic and magnetohydrodynamic instabilities.

description: This study describes a simple, sensitive, specific and generic HPLC-DAD method for simultaneous determination of four drugs prescribed for treatment of Hepatitis C Virus (HCV) infection. Investigated drugs include daclatasvir (DAC), ledipasvir (LED), sofosbuvir (SOF) and ribavirin (RIB). Successful separation was accomplished using Thermohypersil BDS-C8 column (4.6 × 250 mm, 5 µm) with gradient elution of the mobile phase consisted of mixed phosphate buffer pH 7.5 and methanol. Gradient elution started with 25% methanol, ramped up linearly to 80% in 15 min then kept constant till the end of the run. Flow rate was 1.5 mL/min. Peak areas were measured at 235, 260, 315, and 332 nm for RIB, SOF, DAC, and LED, respectively. Peaks of the analytes were perfectly resolved with retention times 2.0, 12.1, 14.7, and 17.2 min for RIB, SOF, DAC, and LED, respectively. The developed method was validated according to ICH guidelines with respect to system suitability, linearity, ranges, accuracy, precision, specificity, robustness, and limits of detection and quantification. The proposed method showed good linearity in the ranges 5–500, 2–300, 0.5–75, and 0.5–75 µg/mL for RIB, SOF, DAC, and LED respectively. Limits of detection were 0.10–0.66 μg/mL for the analyzed drugs. Specificity was established by separation of target drugs from 7 process-related impurities for SOF including its major metabolite (GS-331007). Applicability of the proposed method to real life situations was assessed through the analysis of four different pharmaceutical formulations and satisfactory results were obtained. Additionally, dissolution profiles of the 4 drugs were studied using the developed method.

description: We use data from 1222 late-type star-forming galaxies in the SDSS IV MaNGA survey to identify regions in which the gas-phase metallicity is anomalously-low compared to expectations from the tight empirical relation between metallicity and stellar surface mass-density at a given stellar mass. We find anomalously low metallicity (ALM) gas in 10% of the star-forming spaxels, and in 25% of the galaxies in the sample. The incidence rate of ALM gas increases strongly with both global and local measures of the specific star-formation rate, and is higher in lower mass galaxies and in the outer regions of galaxies. The incidence rate is also significantly higher in morphologically disturbed galaxies. We estimate that the lifetimes of the ALM regions are a few hundred Myr. We argue that the ALM gas has been delivered to its present location by a combination of interactions, mergers, and accretion from the halo, and that this infusion of gas stimulates star-formation. Given the estimated lifetime and duty cycle of such events, we estimate that the time-averaged accretion rate of ALM gas is similar to the star-formation rate in late type galaxies over the mass-range M$_* \sim10^9$ to 10$^{10}$ M$_{\odot}$.

Taraxacum borovezum

description: Taraxacum borovezum Doll (1978: 635, Plate LXXIII), described as a member of T. sect. Alpestria
 Type indication:—“Typus: Holotypus im h Doll / Locus typicus: Borovez, am Sessellift, ca. 1600 m. 11. 7. 76. Doll“; also Plate LXXIII: „ Taraxacum borovezum Doll sp. nov. – Holotypus ”.
 Type:— Flora von Bulgarien, Rila-Gebirge, Borovez, Sessellift., 11 Jul [19]76, R. Doll [as Taraxacum borovezum] (JE, no. det. 19056, holotype; isotype: JE, no. det. 19055).
Specimens of the OM:—There are three specimens belonging to the OM. Herbarium sheet I (JE, no. det. 19055) is in an envelope labelled as Holotype; there are two poorly developed plantlets, not photographed for Plate LXXIII. They may be conspecific with the holotype – Sheet II (JE, no. det. 19056). The latter herbarium sheet contains two plants with relatively well developed leaves, remnants of florets and ripe achenes, both plants are on Plate LXXIII, and represent an evident holotype. The sheet III (JE, no. det. 19057) does not bear any collection date, nor an exact locality. Plants on it probably are conspecific with the holotype. – There is a problem associated with the collection date of the holotype specimen. The protologue gives July 11, 1976, as the collection date, and this date corresponds to what was written on the label by R. Doll originally. However, R. Doll corrected the date later, and gave July 7 as the collection date of the holotype, and the same date is on the isotype label. A check of other taxa for collection dates along the „Sessellift“ [cableway] does not help because both July 11 and July 7 were collection days. We suppose that R. Doll corrected the date later, after the publication date; the correction does not affect the validity of the name nor the typification, in our opinion.
 Conclusion:—In all likelihood, the OM of T. borovezum is homogeneous and represents a taxon that is clearly conspecific with the holotype of T. erzincanense Doll (1975: 199), the correct name for this taxon. This identification is quite certain, despite the low quality of the type gathering of T. borovezum. The name itself is rather mangled grammatically; it was probably meant to be derived from the local village name Borovets [Боровец]. Taraxacum erzincanense is a relatively widespread, phytogeographically important species of an unclear sectional position.

Energy Production in the Formation of a Finite Thickness Cosmic String

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

description: The classical electromagnetic modes outside a long, straight, superconducting cosmic string are calculated, assuming the string to be surrounded by a superconducting cylindric surface of radius R. Thereafter, by use of a Bogoliubov-type argument, the electromagnetic energy W produced per unit length in the lowest two modes is calculated when the string is formed "suddenly". The essential new element in the present analysis as compared with prior work of Parker [Phys. Rev. Lett. {\bf 59}, 1369 (1987)] and Brevik and Toverud [Phys. Rev. D {\bf 51}, 691 (1995)], is that the radius {\it a} of the string is assumed finite, thus necessitating Neumann functions to be included in the fundamental modes. We find that the theory is changed significantly: W is now strongly concentrated in the lowest mode $(m,s)=(0,1)$, whereas the proportionality $W \propto (Gμ/t)^2$ that is characteristic for zero-width strings is found in the next mode (1,1). Here G is the gravitational constant, $μ$ the string mass per unit length, and t the GUT time.

description: The design, fabrication, operation, and performance of a helium-3/4 dilution refrigerator and superconducting magnet system for holding a frozen-spin polarized hydrogen deuteride target in the Jefferson Laboratory CLAS detector during photon beam running is reported. The device operates both vertically (for target loading) and horizontally (for target bombardment). The device proves capable of maintaining a base temperature of 50 mK and a holding field of 1 Tesla for extended periods. These characteristics enabled multi-month polarization lifetimes for frozen spin HD targets having proton polarization of up to 50% and deuteron up to 27%.

description: We present a spectral method for solving elliptic equations which arise in general relativity, namely three-dimensional scalar Poisson equations, as well as generalized vectorial Poisson equations of the type $Δ\vec{N} + λ\vec{\nabla}(\vec{\nabla}\cdot \vec{N}) = \vec{S}$ with $λ\not= -1$. The source can extend in all the Euclidean space ${\bf R}^3$, provided it decays at least as $r^{-3}$. A multi-domain approach is used, along with spherical coordinates $(r,θ,ϕ)$. In each domain, Chebyshev polynomials (in $r$ or $1/r$) and spherical harmonics (in $θ$ and $ϕ$) expansions are used. If the source decays as $r^{-k}$ the error of the numerical solution is shown to decrease at least as $N^{-2(k-2)}$, where $N$ is the number of Chebyshev coefficients. The error is even evanescent, i.e. decreases as $\exp(-N)$, if the source does not contain any spherical harmonics of index $l\geq k -3$ (scalar case) or $l\geq k-5$ (vectorial case).

description: Many atomically thin exfoliated 2D materials degrade when exposed to ambient conditions. They can be protected and investigated by means of transport and optical measurements if they are encapsulated between chemically inert single layers in the controlled atmosphere of a glove box. Here, we demonstrate that the same encapsulation procedure is also compatible with scanning tunneling microscopy (STM) and spectroscopy (STS). To this end, we report a systematic STM/STS investigation of a model system consisting of an exfoliated 2H-NbSe2 crystal capped with a protective 2H-MoS2 monolayer. We observe different electronic coupling between MoS2 and NbSe2, from a strong coupling when their lattices are aligned within a few degrees to 2 essentially no coupling for 30° misaligned layers. We show that STM always probes intrinsic NbSe2 properties such as the superconducting gap and charge density wave at low temperature when setting the tunneling bias inside the MoS2 band gap, irrespective of the relative angle between the NbSe2 and MoS2 lattices. This study demonstrates that encapsulation is fully compatible with STM/STS investigations of 2D materials.

 Type:— Flora von Bulgarien, Rila-Gebirge, Malowitza-Hütte, ca. 2400 m. 16 Jul [19]76, R. Doll [as Taraxacum malowitzum sp. nov. Holotypus!] (JE, no. det. 19408, holotype).
 Specimens of the OM:—The OM of T. malowitzum consists of a single herbarium specimen, the one photographed on Plate LXXV. There are two leaf rosettes, perhaps originally forming a single one, with ripe achenes available. The specimen represents the holotype.
 Conclusion:—The distinctive characters of achenes on the type specimen of T. malowitzum make it possible to equate this name with the earlier T. amborum Haglund (1934: 25).

description: Extruded barley based snacks containing pumpkin and lentils were prepared using a single screw extruder. The response surface methodology was used to optimize and evaluate the effect of three independent variables, namely: mix composition (50-90% barley flour; 2-42% lentil flour and 8% pumpkin flour), moisture content (13% -21%), and temperature cylinder (115-155 ° C). The response variables were: specific mechanical energy (MSE), bulk density (B), expansion coefficient (CR), hardness. It has been found that a low barrel temperature and low moisture content increase the lateral expansion of the extrudate, while a low barley content significantly reduces the lateral expansion of the extrudates. A higher moisture content indicates a positive effect on the hardness of the extrudate, while a higher barley content significantly reduces the hardness. Lower bulk density values were observed at lower moisture values. The specific mechanical energy of the barley-based extrudates ranged from 750.5 to 1097 kJ / kg, with a low moisture content, a significant decrease in the specific mechanical energy was observed.

description: Using real-space renormalisation techniques we analyse the Ising model on a Sierpiński gasket with anisotropic microscopic couplings, and observe a restoration of isotropy on macroscopic scales. In particular, via use of a decimation procedure directly on the fractal lattice, we calculate explicitly the exponential anisotropy decay coefficients near the isotropic regime for both ferromagnetic and antiferromagnetic systems. The results suggest the universality of the phenomenon in lattice field theories on fractals.

description: Introduction: Large-scale disordered coastal aquaculture development causes severe environmental problems. However, quantitative assessments of spatiotemporal dynamics and driving factors for coastal aquaculture are essential and urgent for coastal aquaculture sustainability.Outcomes:Using remote sensing products and geographic information science, we investigated the long-term landscape changes due to coastal aquaculture, and explored its underlying driving factors in the Ningde coastal region, Southeastern China. Results show that coastal aquaculture area increased from 90.65 km2 in 2003 to 96.08 km2 in 2016, and its structure underwent tremendous changes. The area of artificial shrimp ponds increased by 496.15% and the area of farmland ponds decreased by 25.81% between 2003 and 2016. In addition, we revealed that from 2003 to 2016, the change trends of the coastal aquaculture area and the entire Ningde coastal region were consistent, and became more fragmented and dispersive. Furthermore, regression results indicate that the growth and attenuation of coastal aquaculture areas were significantly affected by the initial coastal aquaculture area in 2003. Discussion and Conclusion:To sustainably manage the coastal ecosystems, we provide several recommendations (e.g., a coupled human and natural systems approach to understanding human-nature interactions, integrated assessment, and systematical spatial planning and monitoring) for future research and management.

description: We use archival daily spot coverage measurements from Howard et al. (1984) to study the rotational modulation of the Sun as though it were a distant star. A quasi-periodic Gaussian process measures the solar rotation period $P_\mathrm{rot} = 26.3 \pm 0.1$ days, and activity cycle period $P_\mathrm{cyc} = 10.7 \pm 0.3$ years. We attempt to search for evidence of differential rotation in variations of the apparent rotation period throughout the activity cycle and do not detect a clear signal of differential rotation, consistent with the null results of the hare-and-hounds exercise of Aigrain et al. (2015). The full reconstructed solar light curve is available online.

3+1 description of silent universes: a uniqueness result for the Petrov type I vacuum case
Creators: name: Mars, Marc
Publisher: name: arXiv
Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Silent universes are studied using a ``3+1'' decomposition of the field equations in order to make progress in proving a recent conjecture that the only silent universes of Petrov type I are spatially homogeneous Bianchi I models. The infinite set of constraints are written in a geometrically clear form as an infinite set of Codacci tensors on the initial hypersurface. In particular, we show that the initial data set for silent universes is ``non-contorted'' and therefore (Beig and Szabados, 1997) isometrically embeddable in a conformally flat spacetime. We prove, by making use of algebraic computing programs, that the conjecture holds in the simpler case when the spacetime is vacuum. This result points to confirming the validity of the conjecture in the general case. Moreover, it provides an invariant characterization of the Kasner metric directly in terms of the Weyl tensor. A physical interpretation of this uniqueness result is briefly discussed.

Critical behaviour of three-dimensional Ising ferromagnets at imperfect surfaces: Bounds on the surface critical exponent $β_1$

description: The critical behaviour of three-dimensional semi-infinite Ising ferromagnets at planar surfaces with (i) random surface-bond disorder or (ii) a terrace of monatomic height and macroscopic size is considered. The Griffiths-Kelly-Sherman correlation inequalities are shown to impose constraints on the order-parameter density at the surface, which yield upper and lower bounds for the surface critical exponent $β_1$. If the surface bonds do not exceed the threshold for supercritical enhancement of the pure system, these bounds force $β_1$ to take the value $β_1^{ord}$ of the latter system's ordinary transition. This explains the robustness of $β_1^{ord}$ to such surface imperfections observed in recent Monte Carlo simulations.

description: Optical signatures of the effective nonlinear couplings among electromagnetic fields in the quantum vacuum can be conveniently described in terms of stimulated photon emission processes induced by strong classical, space-time dependent electromagnetic fields. Recent studies have adopted this approach to study collisions of Gaussian laser pulses in paraxial approximation. The present study extends these investigations beyond the paraxial approximation by using an efficient numerical solver for the classical input fields. This new numerical code allows for a consistent theoretical description of optical signatures of QED vacuum nonlinearities in generic electromagnetic fields governed by Maxwell's equations in the vacuum, such as manifestly non-paraxial laser pulses. Our code is based on a locally constant field approximation of the Heisenberg-Euler effective Lagrangian. As this approximation is applicable for essentially all optical high-intensity laser experiments, our code is capable of calculating signal photon emission amplitudes in completely generic input field configurations, limited only by numerical cost.

Ab initio evaluation of the charge-ordering in $α^\prime NaV_2O_5$

description: We report {\it ab initio} calculations of the charge ordering in $α^\prime NaV_2O_5$ using large configurations interaction methods on embedded fragments. Our major result is that the $2p_y$ electrons of the bridging oxygen of the rungs present a very strong magnetic character and should thus be explicitly considered in any relevant effective model. The most striking consequence of this result is that the spin and charge ordering differ substantially, as differ the experimental results depending on whether they are sensitive to the spin or charge density.

description: The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey provides precise chemical abundances of 18 chemical elements for $\sim$ 176,000 red giant stars distributed over much of the Milky Way Galaxy (MW), and includes observations of the core of the Sagittarius dwarf spheroidal galaxy (Sgr). The APOGEE chemical abundance patterns of Sgr have revealed that it is chemically distinct from the MW in most chemical elements. We employ a \emph{k}-means clustering algorithm to 6-dimensional chemical space defined by [(C+N)/Fe], [O/Fe], [Mg/Fe], [Al/Fe], [Mn/Fe], and [Ni/Fe] to identify 62 MW stars in the APOGEE sample that have Sgr-like chemical abundances. Of the 62 stars, 35 have \emph{Gaia} kinematics and positions consistent with those predicted by \emph{N}-body simulations of the Sgr stream, and are likely stars that have been stripped from Sgr during the last two pericenter passages ($

description: The ground states of the Bernasconi model are binary +1/-1 sequences of length N with low autocorrelations. We introduce the notion of perfect sequences, binary sequences with one-valued off-peak correlations of minimum amount. If they exist, they are ground states. Using results from the mathematical theory of cyclic difference sets, we specify all values of N for which perfect sequences do exist and how to construct them. For other values of N, we investigate almost perfect sequences, i.e. sequences with two-valued off-peak correlations of minimum amount. Numerical and analytical results support the conjecture that almost perfect sequences do exist for all values of N, but that they are not always ground states. We present a construction for low-energy configurations that works if N is the product of two odd primes.

description: We consider the motion of a spinning relativistic particle with an arbitrary value of spin in external electromagnetic and gravitational fields, to first order in the external field. We use the noncovariant description of spin. An explicit expression is obtained for the interaction of second order in spin. The value of the quadrupole moment is found for which this interaction decreases when the energy grows.

Self force on particle in orbit around a black hole

Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We study the self force acting on a scalar charge in uniform circular motion around a Schwarzschild black hole. The analysis is based on a direct calculation of the self force via mode decomposition, and on a regularization procedure based on Ori's mode-sum regularization prescription. We find the four self-force at arbitrary radii and angular velocities (both geodesic and non-geodesic), in particular near the black hole, where general-relativistic effects are strongest, and for fast motion. We find the radial component of the self force to be repulsive or attractive, depending on the orbit.

description: We have studied dilute Bose-Bose mixtures of atoms with attractive interspecies and repulsive intraspecies interactions using quantum Monte Carlo methods at $T=0$. Using a number of models for interactions, we determine the range of validity of the universal equation of state of the symmetric liquid mixture as a function of two parameters: the $s$-wave scattering length and the effective range of the interaction potential. It is shown that the Lee-Huang-Yang correction is sufficient only for extremely dilute liquids with the additional restriction that the range of the potential is small enough. Based on the quantum Monte Carlo equation of state we develop a new density functional which goes beyond the Lee-Huang-Yang term and use it together with local density approximation to determine density profiles of realistic self-bound drops.

Relaxation time of weakly interacting superparamagnets

description: The relaxation time of weakly interacting classical spins is calculated by introducing the averages of the local dipolar field, obtained by thermodynamic perturbation theory, in a rigorous expression for the single-spin thermoactivation rate in a weak but arbitrarily oriented field. At low temperatures the non-trivial dependence of the superparamagnetic blocking on the damping coefficient, numerically found by Berkov and Gorn, is reproduced by our model and interpreted in terms of the deviations from uniaxial anisotropy associated to the transversal component of the dipolar field acting on each spin.

description: Taraxacum plovdivense Doll (1978: 629, Plate LXXI), described as a member of T. sect. Erythrocarpa
 Type indication:—“Typus: Holotypus im h Doll / Locus typicus: Plovdiv, Wegrand. 9. 7. 76. Doll“; also Plate LXXI: „ Taraxacum plovdivense Doll sp. nov. – Holotypus ”.
 Type:— Plovdiv, Wegrand., 9 Jul 1976, R. Doll [as Taraxacum plovdivense sp. nov.] (JE, no. det. 9164, holotype).
Specimens of the OM:— A single specimen of the OM corresponds to the Plate LXXI (Doll 1978) and consists of a plant with flowers (pollen irregular in size), and a part of the same rosette and a few fragments and achenes in an envelope. It is not possible to interpret this name on the basis of an extremely late, not well preserved specimen.
 Conclusion:—The name T. plovdivense is left without interpretation, as a nomen damnabile. It does not belong to T. sect. Erythrocarpa, otherwise its sectional position remains unclear.

description: Experimentation as a method of design was announced in Bauhaus Weimar in the early twentieth century. In 1920, Gropius developed the concept of “Baukasten im großen” (Building Blocks at Large) – a building set of six elements in scale 1:1. Based on this principle, only one experimental building was realized – “Haus am Horn.” In the late 1990s, Bauhaus-University Weimar initiated the project “Neues Bauen am Horn” – an experiment of building Bauhaus style dwellings adapted to the new socio-economic situation.

Drawing, drafting, designing, and pasting

Publisher: name: AIS - Architecture Image Studies

description: In architectural drawings, human figures are generally requested to express the scale of design space and to illustrate the functions, but many cases demonstrate they are capable of playing cultural roles, indirectly revealing the architects’ ideological positions toward society. By comparing their use in the work of Otto Wagner, Mies van de Rohe, Le Corbusier, and Mansilla and Tuñón, this article analyses their role as visual mediator between representation and reality according to the different graphical techniques and their intertextual potential to connote the representation and the specific figures adopted. In particular, it focuses on the case of the cameo, and the cameo of the architect in particular, to discuss the semantic consequences on the drawing and to frame it into the wider, pictorial typology of the portrait of an architect.

description: Computably enumerable equivalence relations (ceers) received a lot of attention in the literature. The standard tool to classify ceers is provided by the computable reducibility $\leq_c$. This gives rise to a rich degree-structure. In this paper, we lift the study of $c$-degrees to the $Δ^0_2$ case. In doing so, we rely on the Ershov hierarchy. For any notation $a$ for a non-zero computable ordinal, we prove several algebraic properties of the degree-structure induced by $\leq_c$ on the $Σ^{-1}_{a}\smallsetminus Π^{-1}_a$ equivalence relations. A special focus of our work is on the (non)existence of infima and suprema of $c$-degrees.
