description: We investigate whether the galaxy and star formation model used for the Auriga simulations can produce a realistic globular cluster (GC) population. We compare statistics of GC candidate star particles in the Auriga haloes with catalogues of the Milky Way (MW) and Andromeda (M31) GC populations. We find that the Auriga simulations do produce sufficient stellar mass for GC candidates at radii and metallicities that are typical for the MW GC system (GCS). We also find varying mass-ratios of the simulated GC candidates relative to the observed mass in the MW and M31 GC systems for different bins of galactocentric radius-metallicity (r$_{\text{gal}}$ -[Fe/H]). Overall, the Auriga simulations produce GC candidates with higher metallicities than the MW and M31 GCS and they are found at larger radii than observed. The Auriga simulations would require bound cluster formation efficiencies higher than ten percent for the metal-poor GC candidates, and those within the Solar radius should experience negligible destruction rates to be consistent with observations. GC candidates in the outer halo, on the other hand, should either have low formation efficiencies, or experience high mass loss for the Auriga simulations to produce a GCS that is consistent with that of the MW or M31. Finally, the scatter in the metallicity as well as in the radial distribution between different Auriga runs is considerably smaller than the differences between that of the MW and M31 GCSs. The Auriga model is unlikely to give rise to a GCS that can be consistent with both galaxies.

description: In this paper we give a method for calculating the rank of a general elliptic curve over the field of rational functions in two variables. We reduce this problem to calculating the cohomology of a singular hypersurface in a weighted projective 4-space. We then give a method for calculating the cohomology of a certain class of singular hypersurfaces, extending work of Dimca for the isolated singularity case.

Linearity and Compound Physical Systems: The Case of Two Separated Spin 1/2 Entities

description: We illustrate some problems that are related to the existence of an underlying linear structure at the level of the property lattice associated with a physical system, for the particular case of two explicitly separated spin 1/2 objects that are considered, and mathematically described, as one compound system. It is shown that the separated product of the property lattices corresponding with the two spin 1/2 objects does not have an underlying linear structure, although the property lattices associated with the subobjects in isolation manifestly do. This is related at a fundamental level to the fact that separated products do not behave well with respect to the covering law (and orthomodularity) of elementary lattice theory. In addition, we discuss the orthogonality relation associated with the separated product in general and consider the related problem of the behavior of the corresponding Sasaki projections as partial state space mappings

description: Two new guaiane-type sesquiterpenes, kwangsiensis A and B (1-2) were isolated from the roots of Curcuma kwangsiensis. Their structures were elucidated by extensive spectroscopic methods, including NMR, circular dichroism (CD) and high-resolution mass-spectrometry. The anti-inflammatory activity of the two compounds was evaluated on the basis of their inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) production in mouse RAW 264.7 macrophages. Compounds 1 and 2 showed moderate inhibitory activities with IC50 values of 27.4 and 35.1 μM, respectively.

description: A new impregnation method was tested in this study. Without a stabilizing agent, silver and copper metallic compounds were directly impregnated on activated carbon using vacuum impregnation followed by drying at 100°C and vacuum impregnation followed by thermal decomposition at 350°C in an ambient atmosphere. The effect of thermal decomposition on the structural, morphological, and textural characteristics of the modified nanomaterials was analysed by Brunauer–Emmett–Teller, X-ray diffraction, scanning electron microscopy, energy dispersive X-Ray, and transmission electron microscopy. The characteristics of the produced materials were not altered. Silver and CuO nanoparticles were identified in the samples with average diameters ranging from 33.3–36.8 nm and 29.0–33.3 nm, respectively. The materials were tested for their antibacterial capacity and for their potential to leach Ag and Cu into water, thus analysing the effect of the thermal decomposition process on the impregnation process. The vacuum impregnation process followed by thermal decomposition produced the best results, with the resultant material reducing bacterial abundance by 5.31–6.61 log and leaching only low concentrations of metals into the water (Ag – 0.010–0.025 mg L−1 and Cu – 0.270–0.361 mg L−1). Samples produced without the thermal decomposition step reached bacterial reductions of 1.86–1.97 log and yielded higher concentrations of metals in the water (Ag – 0.051–0.086 mg L−1 and Cu – 0.819–0.894 mg L−1).

description: The spreading of the X-line out of the reconnection plane under a strong guide field is investigated using large-scale three-dimensional (3D) particle-in-cell (PIC) simulations in asymmetric magnetic reconnection. A simulation with a thick, ion-scale equilibrium current sheet (CS) reveals that the X-line spreads at the ambient ion/electron drift speeds, significantly slower than the Alfvén speed based on the guide field $V_{Ag}$. Additional simulations with a thinner, sub-ion-scale CS show that the X-line spreads at $V_{Ag}$ (Alfvénic spreading), much higher than the ambient species drifts. An Alfvénic signal consistent with kinetic Alfvén waves develops and propagates, leading to CS thinning and extending, which then results in reconnection onset. The continuous onset of reconnection in the signal propagation direction manifests as Alfvénic X-line spreading. The strong dependence on the CS thickness of the spreading speeds, and the X-line orientation are consistent with the collisionless tearing instability. Our simulations indicate that when the collisionless tearing growth is sufficiently strong in a thinner CS such that $γ/Ω_{ci}\gtrsim\mathcal{O}(1)$, Alfvénic X-line spreading can take place. Our results compare favorably with a number of numerical simulations and recent magnetopause observations. A key implications is that the magnetopause CS is typically too thick for Alfvénic X-line spreading to effectively take place.

description: We describe the possible Mordell-Weil groups for degree 1 elliptic threefold with rational base and constant $j$-invariant. Moreover, we classify all such elliptic threefolds if the $j$-invariant is nonzero. We can use this classification to describe a class of singular hypersurfaces in $\Ps(2,3,1,1,1)$ that admit no variation of Hodge structure.

description: Biodiesel is considered to be a natural substitute for fossil fuel. The comparatively low toxicity of biodiesel and its susceptibility to microbial biodegradation could reduce its environmental impact. Currently, biodiesel is sold previously mixed with petroleum-based hydrocarbons. The aim of this work was to measure the biodegradation potential of commercially available biodiesel, using bacterial strains (BBCOL-001, BBCOL-002, and BBCOL-003) isolated from a tropical forest soils in the Colombian Caribbean. According to nucleotide sequencing of the gene encoding for 16S rRNA, the strains belong to members of the genus Cellulosimicrobium. GC–MS analysis showed that biodiesel-oil alkanes were degraded by an average of 81.5% with optical density reaching 0.2–0.3 in minimal salt media at 37°C for 5 days. Individual diesel-oil alkanes were degraded by the strains at rates between 64.9% to 100%. The increase in bacterial biomass confirmed the use of the substrates by the microorganisms, suggesting these hydrocarbons are a carbon source. Changes in the biochemical behaviour of the strains suggested their capacity to adapt to environmental conditions might be an important resource for bioremediation.

description: We construct optimal protocols for verifying qubit and qudit GHZ states using local projective measurements. When the local dimension is a prime, an optimal protocol is constructed from Pauli measurements only. Our protocols provide a highly efficient way for estimating the fidelity and certifying genuine multipartite entanglement. In particular, they enable the certification of genuine multipartite entanglement using only one test when the local dimension is sufficiently large. By virtue of adaptive local projective measurements, we then construct protocols for verifying GHZ-like states that are optimal over all protocols based on one-way communication. The efficiency can be improved further if additional communications are allowed. Finally, we construct optimal protocols for verifying GHZ states and nearly optimal protocols for GHZ-like states in the adversarial scenario.

Interstellar scintillation as the origin of rapid radio variability in the quasar J1819+3845

description: Quasars shine brightly due to the liberation of gravitational energy as matter falls onto a supermassive black hole in the centre of a galaxy. Variations in the radiation received from active galactic nuclei (AGN) are studied at all wavelengths, revealing the tiny dimensions of the region and the processes of fuelling the black hole. Some AGN are variable at optical and shorter wavelengths, and display radio outbursts over years and decades. These AGN often also show faster variations at radio wavelengths (intraday variability, IDV) which have been the subject of much debate. The simplest explanation, supported by a correlation in some sources between the optical (intrinsic) and faster radio variations, is that the rapid radio variations are intrinsic. However, this explanation implies physically difficult brightness temperatures, suggesting that the variations may be due to scattering of the incident radiation in the interstellar medium of our Galaxy. Here we present results which show unambiguously that the variations in one extreme case are due to interstellar scintillation. We also measure the transverse velocity of the scattering material, revealing a surprising high velocity plasma close to the Solar System.

description: The Casimir stress on two concentric spherical shell in de Sitter background for massless scalar field is calculated. The scalar field satisfies Dirichlet boundary conditions on the spheres. The metric is written in conformally flat form to make maximum use of Minkowski space calculations. Then the Casimir stress is calculated for inside and outside of the shell with different backgrounds. This model may be used to study the effect of the Casimir stress on the dynamics of the domain wall formation in inflationary models of early universe.

description: Let $C=Z(f)$ be a reduced plane curve of degree $6k$, with only nodes and ordinary cusps as singularities. Let $I$ be the ideal of the points where $C$ has a cusp. Let $\oplus S(-b_i)\to \oplus S(-a_i) \to S\to S/I$ be a minimal resolution of $I$. We show that $b_i\leq 5k$. From this we obtain that the Mordell-Weil rank of the elliptic threefold $W:y^2=x^3+f$ equals $2#\{i\mid b_i=5k\}$. Using this we find an upper bound for the Mordell-Weil rank of $W$, which is $1/18 (125+\sqrt{73}-\sqrt{2302-106\sqrt{73}})k+l.o.t.$ and we find an upper bound for the exponent of $(t^2-t+1)$ in the Alexander polynomial of $C$, which is $1/36(125+\sqrt{73}-\sqrt{2302-106\sqrt{73}})k+l.o.t.$. This improves a recent bound of Cogolludo and Libgober almost by a factor 2.

description: Respiratory modulation of sympathetic nerve activity (respSNA) was studied in a hypertensive rodent model of chronic kidney disease (CKD) using Lewis Polycystic Kidney (LPK) rats and Lewis controls. In adult animals under in vivo anaesthetised conditions (n=8-10/strain), respiratory modulation of splanchnic and renal nerve activity was compared under control conditions, and during peripheral (hypoxia), and central, chemoreceptor (hypercapnia) challenge. RespSNA was increased in the LPK vs. Lewis (area under curve (AUC) splanchnic and renal: 8.7$\pm$1.1 vs. 3.5$\pm$0.5 and 10.6$\pm$1.1 vs. 7.1$\pm$0.2 $μ$V.s, respectively, P<0.05). Hypoxia and hypercapnia increased respSNA in both strains but the magnitude of the response was greater in LPK, particularly in response to hypoxia. In juvenile animals studied using a working heart brainstem preparation (n=7-10/strain), increased respSNA was evident in the LPK (thoracic SNA, AUC: 0.86$\pm$0.1 vs. 0.42$\pm$0.1 $μ$V.s, P<0.05), and activation of peripheral chemoreceptors (NaCN) again drove a larger increase in respSNA in the LPK with no difference in the response to hypercapnia. Amplified respSNA occurs in CKD and may contribute to the development of hypertension.

 Este trabajo propone una Estrategia Integrada basada en Procesos, Requerimientos, Medición y Evaluación, cuyo objetivo es identificar y mantener la trazabilidad de los requerimientos en forma temprana en proyectos de almacenes de datos, a partir de la formalización de los procesos de negocios, y de la definición formal del proyecto de medición y evaluación que soportará el proceso de toma de decisión. Esto permite avanzar sobre la delimitación del alcance del proyecto, la identificación temprana de sus riesgos, a la vez que establece un mecanismo de trazabilidad entre las decisiones y artefactos que se generan a lo largo de su ciclo de vida. Esto representa un complemento importante sobre ciclos de vida como el propuesto por Kimball, en donde la fase de requerimientos no está formalizada, y no existe una estrategia por la cual se defina claramente aquellos aspectos que se desean cuantificar y-o a analizar a los efectos de soportar un proceso de toma de decisión.

description: In this letter, we report on a unique device design strategy for increasing the breakdown voltage and hence Baliga Figure of Merit (BFOM) of III-nitride HEMTs by engineering the gate edge towards the drain. The breakdown of such devices with meandering gate-drain access region (M-HEMT) are found to be 62% more compared to that of conventional HEMT while the ON resistance suffers by 76%, leading to an overall improvement in the BFOM for by 28%. 3D-TCAD simulations show that the decrease in the peak electric field at the gate edge was responsible for increased breakdown voltage.

description: The interaction of high-velocity neutron stars with the interstellar medium produces bow shock nebulae, where the relativistic neutron star wind is confined by ram pressure. We present multi-wavelength observations of the Guitar Nebula, including narrow-band H-alpha imaging with HST/WFPC2, which resolves the head of the bow shock. The HST observations are used to fit for the inclination of the pulsar velocity vector to the line of sight, and to determine the combination of spindown energy loss, velocity, and ambient density that sets the scale of the bow shock. We find that the velocity vector is most likely in the plane of the sky. We use the Guitar Nebula and other observed neutron star bow shocks to test scaling laws for their size and H-alpha emission, discuss their prevalence, and present criteria for their detectability in targeted searches. The set of H-alpha bow shocks shows remarkable consistency, in spite of the expected variation in ambient densities and orientations. Together, they support the assumption that a pulsar's spindown energy losses are carried away by a relativistic wind that is indistinguishable from being isotropic. Comparison of H-alpha bow shocks with X-ray and nonthermal, radio-synchrotron bow shocks produced by neutron stars indicates that the overall shape and scaling is consistent with the same physics. It also appears that nonthermal radio emission and H-alpha emission are mutually exclusive in the known objects and perhaps in all objects.

description: Australia produces 98% of the world’s fine wool. Fine wool attracts price premiums at auction. Fine wool can be much more susceptible to breakage as a result of low staple strength or ‘tender’ wool. Tender wool receives discounts that can range from 3% to up to 30%. This can greatly impact on farm wool income. To evaluate the management strategies for overcoming poor staple strength, producers need to determine whether staple strength is a problem in their wool clip, and the cost to their business in forgone income as a result of strength discounts. This study explored whether wool of poor staple strength is a problem in South West Victoria. Based on a Case Study and on industry data it was found that wool with poor staple strength can comprise almost a third of wool sold. The severity of price discounts for tender wool changes from year to year. In years of high wool prices, and high discounts and premiums, staple strength was a key contributor to profit. In these years, profit from wool of sound strength almost doubled the profit from tender wool. In years where the wool price and discounts were low, the difference in operating profit was very marginal, with staple strength having little effect on final profits. Managing to avoid or reduce tender wool in reproducing ewes cost $3.29 per ewe to improve staple strength by 5 N/ktex. There were increases in income of $8.98 per ewe in 2001-02 and $7.09 in 2002-03 but management costs outweighed the income benefits in years of lower wool prices.

description: We compute the Boundary Superstring Field Theory partition function on the annulus in the presence of independent linear tachyon profiles on the two boundaries. The R-R sector is found to contribute non-trivially to the derivative terms of the space-time effective action. In the process we construct a boundary state description of D-branes in the presence of a linear tachyon. We quantize the open string in a tachyonic background and address the question of open/closed string duality.

description: Jerrum, Sinclair and Vigoda (2004) showed that the permanent of any square matrix can be estimated in polynomial time. This computation can be viewed as approximating the partition function of edge-weighted matchings in a bipartite graph. Equivalently, this may be viewed as approximating the partition function of vertex-weighted independent sets in the line graph of a bipartite graph. Line graphs of bipartite graphs are perfect graphs, and are known to be precisely the class of (claw, diamond, odd hole)-free graphs. So how far does the result of Jerrum, Sinclair and Vigoda extend? We first show that it extends to (claw, odd hole)-free graphs, and then show that it extends to the even larger class of (fork, odd hole)-free graphs. Our techniques are based on graph decompositions, which have been the focus of much recent work in structural graph theory, and on structural results of Chvatal and Sbihi (1988), Maffray and Reed (1999) and Lozin and Milanic (2008).

COMMENT
Jelenc (1955a) reported this species based on the previous one of Bescherelle (1882) from La Calle as Campylopus polytrichoides De Not. considering both names as synonyms. Nevertheless, posterior taxonomical studies by Gradstein & Sipman (1978) differentiate clearly both species and confirmed that at that time the reports in northern Africa correspond to C. pilif er.

description: We develop a model of two-sided matching problem with individual-sided envious preferences that originate from an emulative envy effect in which a more desirable state that is preferred is owned by the other individual. We assume envious preferences influence an individual’s decision to enter into a two-sided network instead of being unassigned. In this paper, we show that an individual-sided envious preference leads to a stable matching under a two-sided market framework. Applying the mechanism of the model to behavioral contract theory, we show that individual-proposing envious acceptance leads to stable farmer-buyer contract matching considering buyer’s time invariant preference. We further argue that individual’s envious preference also contributes to herd-type acceptance that dominates individual’s logical preferences in participation decision under a less risky environment.

description: Building on studies on the political business cycle, the literature on welfare state retrenchment has argued that governments which cut the welfare state try to avoid blame by implementing painful measures in the beginning of the mandate and expanding benefits as elections approach. In contrast to this linear relationship, this article argues that governments often feel pressured to fulfil (mostly expansionary) campaign promises during the first months in office. Consequently, cutting right away is not what should be expected. Instead, a more nuanced, U-shaped timing trajectory is probable with a period in the beginning characterised by both cuts and fulfilment of expansionary pledges, followed by a period of cutbacks, and finally an expansive phase towards the end of a mandate. This argument is tested on our new original dataset of legislative changes in five European countries – Britain, Denmark, Finland, France and Germany – during the last four decades.

description: We compare effects of research quality and quantity on the salary of academics in agricultural economics and economics departments of the same universities. Agricultural economists get a significantly lower payoff to research quality, whether measured in terms of citations or in terms of quality-weighted journal output (based on nine different weighting schemes). Instead, salary in these agricultural economics departments appears to depend on the quantity of journal articles. In contrast, article counts have no independent effect on economist salaries. One-third of academics in the agricultural economics departments studied here have doctoral training in economics; these very different reward structures for research may cause frustration for these faculty due to the muted returns to research quality that agricultural economics departments seem to offer.

description: Context. Since 1998, a planet-search around main sequence stars within 50~pc in the southern hemisphere has been carried out with the CORALIE spectrograph at La Silla Observatory. Aims. With an observing time span of more than 20 years, the CORALIE survey is able to detect long term trends in data with masses and separations large enough to select ideal targets for direct imaging. Detecting these giant companion candidates will allow us to start bridging the gap between radial velocity detected exoplanets and directly imaged planets and brown dwarfs. Methods. Long-term precise Doppler measurements with the CORALIE spectrograph reveal radial velocity signatures of massive planetary companions and brown dwarfs on long-period orbits. Results. In this paper we report the discovery of new companions orbiting HD~181234, HD~13724, HD~25015, HD~92987 and HD~50499. We also report updated orbital parameters for HD~50499b, HD~92788b and HD~98649b. In addition, we confirm the recent detection of HD~92788c. The newly reported companions span a period range of 15.6 to 40.4 years and a mass domain of 2.93 to 26.77 $M_{\mathrm{Jup}}$, the latter of which straddles the nominal boundary between planets and brown dwarfs. Conclusion. We have reported the detection of five new companions and updated parameters of four known extrasolar planets. We identify at least some of these companions to be promising candidates for imaging and further characterisation.

Advanced Chemical Transport Modeling of Fine Particulate Matter to Support Exposure Assessment

description: Fine particulate matter with aerodynamic diameter less than 2.5 μm (PM2.5) has been associated with public health concerns due to short and long-term exposure. Chemical transport models (CMTs) are frequently used for developing air quality and emissions control policies that protect public health. To evaluate these policies, Chemical transport models (CTMs) must simulate PM2.5 concentrations and their response to changes in emissions accurately. At high resolutions, the geographical distribution of PM2.5 concentrations can have sharp gradients. During the last decades, regulations by the U.S. Environmental Protection Agency have led to significant reductions of the emissions of atmospheric pollutants including PM2.5.
The CTM PMCAMx is used here to assess the impact of increasing model resolution on the model’s ability to predict the variability, sources and population exposure of PM2.5 concentrations at 36 x 36, 12 x 12, 4 x 4 and 1 x 1 km resolutions over the city of Pittsburgh; to evaluate the PMCAMx predictions at various grid resolutions against measurements of PM2.5 concentration and composition; and to estimate the concentration, composition and sources of PM2.5 over 20 years in the U.S.
At the finest resolution, the model successfully resolved intra-urban variations and individual roadways. Pollutants with significant local emissions such as elemental and organic carbon have gradients that can only be resolved at the finest resolution. PMCAMx predicts sulfate, elemental carbon and organic aerosol concentrations well with fractional biases below 10%. Agreement with total PM2.5 measurements is also encouraging with a fractional bias of 3%. Prediction performance improves with increasing resolution reducing the average fractional error from 16% at 36 x 36 km to 12% at 1 x 1 km. EC concentrations reduced by 23% due to a 37% reduction on emissions from 1990 to 2010. SO2 emissions were reduced by 63% causing a large reduction of sulfate concentrations in the northeast of the U.S. A comparison between the predicted and observed reductions of EC, sulfate, and PM2.5 showed excellent correlations.
