Temnothorax ibericus

description: Temnothorax ibericus (Menozzi, 1922)
(Fig. 2C and 6C)
 Material. 2 workers, Spain, Sierra de Javalambre (Teruel), 5.VI.2015, 1648 m, Daniel Sánchez leg.; 4 workers, Jaén, J. Reyes-López leg.; 5 workers, Lamiana-Escuaín (Huesca), 29.VII.2008, 42°35’01.9”N 0°10’06.0”E, 1080 m, Ramón Antor leg.
 Diagnosis. Characterized within the Iberian sordidulus species-complex by its dark coloration, prominent superimposed longitudinal striae of head, well-defined metanotal groove, short propodeal spines and relatively wide postpetiole (PPW/CS usually>0.400). Smallest species of the complex (mean CS 0.548 mm).
 Comments. T. ibericus is most similar to T. sordidulus; they both show dark coloration with infuscate antennal clubs, elongated head, developed metanotal groove, short propodeal spines, rounded petiolar apex and short subpetiolar process. Its status as a differentiated species is justified by its more pronounced superimposed longitudinal striae on head, less developed reticulated ground sculpture of frons, less impressed metanotal groove and wider postpetiole of the complex. T. ibericus has been classically considered a member of the exilis species-group, but the reticulated ground sculpture, visible metanotal groove and petiolar shape perfectly match the concept of the sordidulus species-complex. The queen also shows the typical aspect of the T. sordidulus queens, with uniform dark coloration and short propodeal spines. Description of nest preferences and morphology of the queen can be found in Espadaler et al. (2017).

description: Accretion disks around active galactic nuclei are potentially unstable to star formation at large radii. We note that when the compact objects formed from some of these stars spiral into the central supermassive black hole, there is no radiative feedback and therefore the accretion rate is not limited by radiation forces. Using a set of accretion disk models, we calculate the accretion rate onto the central supermassive black hole in both gas and compact objects. We find that the timescale for a supermassive black hole to double in mass can decrease by factors ranging from $\sim0.7$ to as low as $\sim0.1$ in extreme cases, compared to gas accretion alone. Our results suggest that the formation of extremely massive black holes at high redshift may occur without prolonged super-Eddington gas accretion or very massive seed black holes. We comment on potential observational signatures as well as implications for other observations of active galactic nuclei.

description: Transport critical current measurements have been performed on 5 degree [001]-tilt thin film YBa2Cu3O7-delta single grain boundaries with magnetic field rotated in the plane of the film, phi. The variation of the critical current has been determined as a function of the angle between the magnetic field and the grain boundary plane. In applied fields above 1 T the critical current, j_c, is found to be strongly suppressed only when the magnetic field is within an angle phi_k of the grain boundary. Outside this angular range the behavior of the artificial grain boundary is dominated by the critical current of the grains. We show that the phi dependence of j_c in the suppressed region is well described by a flux cutting model.

description: Interest Rates Movement during Global Financial Crisis and Its Impact on the Banking Sector
ABSTRACT This paper aimed to explain general framework of relationship between structural transition of Turkish Banking Sector between 2002-2010 and interest rates, interest margins. In last eight years nominal and real interest rates significantly declined. In banks’ balance sheets loans share increased, in contrast securities share decreased. Bank’s balance sheet management is defined as an optimization problem and factors affecting profit maximization which assumed objective function of the problem explained. In a market with low interest rates and margins, effective management of non-interest income and expense items importance determined. In the forthcoming periods, analysis results shows that banking sector should concentrate on factors such as regulation, cost management, risk management, capital management, competitive structure, product variety and economies of scale.
ÖZET Bu çalışmada, Türk Bankacılık Sektörünün 2002-2010 yılları arasında geçirdiği yapısal dönüşümün faiz oranları ve marjları ile ilişkisinin genel çerçevesinin çizilmesi amaçlanmaktadır. Son sekiz yıl içerisinde nominal ve reel faiz oranlarında önemli bir düşüş gerçekleşmiştir. Bu dönemde banka bilançoları içerisinde kredilerin payı artış göstermiş, menkul değerlerin payı azalış göstermiştir. Banka bilanço yönetimi bir optimizasyon problemi olarak ele alınmış ve problemin amaç fonksiyonu olarak varsayılan kâr maksimizasyonunu etkileyen unsurlar açıklanmıştır. Düşük faiz oranı ve marjların geçerli olduğu bir piyasada faiz dışı gelir ve gider kalemlerinin etkin yönetilmesinin önemi tespit edilmiştir. Önümüzdeki dönemde analiz sonuçları, bankacılık sektörünün regülasyon, maliyet yönetimi, risk yönetimi, sermaye yönetimi, teknolojik altyapı, rekabetçi yapı, ürün çeşitliliği ve ölçek ekonomisi gibi faktörler üzerinde yoğunlaşması gerektiğini göstermektedir.

description: The Green Bank Telescope (GBT) Diffuse Ionized Gas Survey (GDIGS) is a fully-sampled radio recombination line (RRL) survey of the inner Galaxy at C-band (4-8 GHz). We average together ~15 Hn$α$ RRLs within the receiver bandpass to improve the spectral signal-to-noise ratio. The average beam size for the RRL observations at these frequencies is ~2'. We grid these data to have spatial and velocity spacings of 30" and 0.5 km/s, respectively. Here we discuss the first RRL data from GDIGS: a six square-degree-area surrounding the Galactic HII region complex W43. We attempt to create a map devoid of emission from discrete HII regions and detect RRL emission from the diffuse ionized gas (DIG) across nearly the entire mapped area. We estimate the intensity of the DIG emission by a simple empirical model, taking only the HII region locations, angular sizes, and RRL intensities into account. The DIG emission is predominantly found at two distinct velocities: ~40 km/s and ~100 km/s. While the 100 km/s component is associated with W43 at a distance of ~6 kpc, the origin of the 40 km/s component is less clear. Since the distribution of the 40 km/s emission cannot be adequately explained by ionizing sources at the same velocity, we hypothesize that the plasma at the two velocity components is interacting, placing the 40 km/s DIG at a similar distance as the 100 km/s emission. We find a correlation between dust temperature and integrated RRL intensity, suggesting that the same radiation field that heats the dust also maintains the ionization of the DIG.

description: The price volatility observed in futures markets, beginning in 2006 and continuing through to the present, has posed challenges to commercial traders attempting to use these markets to hedge their price risk. Additionally, speculative activity in these markets is seemingly on the rise, with large index funds drawing the ire of many as a possible driver of price volatility and high price levels. Taken in concert, these issues have led some to question the ability of the markets to continue to provide for adequate hedging functionality. In this paper, we attempt to determine if the rate at which commercial traders hedge in the markets has changed by testing for structural change in the relationship between open interest and physical grain stocks. A significant structural break is found in the wheat market in late 2004. A more detailed examination of the break is done by incorporating smooth transition and threshold models, with the positive relationship between open interest and stocks shown to decline to statistically zero around the structural break. Given the development of non-convergence in the wheat market at this time, it suggests that wheat hedgers might be using alternative hedging outlets. Overall, the estimated models show generally poor fits, indicating that there might be other factors than are present in the structural model influencing hedgers’ positions in futures markets.

description: This paper analyzes changes in the expected demand for corn in the U.S., and it explores whether anticipatory signals of price jumps can be obtained from simple models. Two main objectives are considered. One is to estimate the relationship between the expected supply of corn and corresponding prices of futures contracts. We argue that such results can provide estimates of demand relationships and their shifts with the passage of time. Moreover, such analysis should allow us to test for possible changes in the structure of demand. A second, related objective is to demonstrate how such historical estimates can allow an analyst to appraise the futures markets’ quotes relative to forecasts from the historical model. We argue that the difference in the two prices may contain useful information.

description: Context. Elemental abundances are of prime importance to help us reconstruct the origin and evolution of stars and galaxies in our Universe. Sulfur abundances have not been as heavily studied as other elements, so some details regarding its behaviour are still unclear. Aims. We aim to investigate [S/Fe] ratios in stars of the solar neighbourhood in order to analyse the chemical evolution of sulfur and probe for possible differences in abundances of planet host and non-planet host stars. Methods. We use the code MOOG to perform spectral synthesis and derive v*sin(i) values and [S/Fe] ratios for 719 FGK stars with high-resolution (R~115000) and high-quality spectra from the HARPS-GTO program. We find the best fit and corresponding parameter values by performing chi-square minimisation of the deviation between synthetic profiles and observational spectra. Results. Our results reveal that sulfur behaves as a typical alpha-element, with low abundances in young thin disk stars and high abundances in old thick disk stars, following what was expected from our understanding of the Galactic chemical evolution (GCE). Nevertheless, further studies into the abundances of sulfur in very metal-poor stars are required as our sample only derived sulfur abundances to stars with metallicity as low as [Fe/H]=-1.13 dex. High-alpha metal rich stars are more enhanced in sulfur compared to their thin disk counterparts at the same metallicity. We compare our results to GCE models from other authors in the [S/Fe] vs. [Fe/H] plane. The [S/Fe]-age relationship is a good proxy for time, just like it is the case with other alpha-elements. We report no differences in the abundances of sulfur between stars with and without planetary companions in the metallicity range [Fe/H] >= -0.3 dex.

description: We introduce a combinatorial curvature flow for PL metrics on compact triangulated 3-manifolds with boundary consisting of surfaces of negative Euler characteristic. The flow tends to find the complete hyperbolic metric with totally geodesic boundary on a manifold. Some of the basic properties of the combinatorial flow are established. The most important ones is that the evolution of the PL curvature satisfies a combinatorial heat equation. It implies that the total curvature decreases along the flow. The local convergence of the flow to the hyperbolic metric is also established if the triangulation is isotopic to a totally geodesic triangulation.

description: The circumgalactic medium (CGM) of the Milky Way is mostly obscured by nearby gas in position-velocity space because we reside inside the Galaxy. Substantial biases exist in most studies on the Milky Way's CGM that focus on easier-to-detect high-velocity gas. With mock observations on a Milky-Way analog from the FOGGIE simulation, we investigate four observational biases related to the Milky Way's CGM. First, QSO absorption-line studies probe a limited amount of the CGM mass: only 35% of the mass is at high Galactic latitudes $|b|>20$ degrees, of which only half is moving at $|v_{\rm LSR}|\gtrsim100$ km s$^{-1}$. Second, the inflow rate ($\dot{M}$) of the cold gas observable in HI 21cm is reduced by a factor of $\sim10$ as we switch from the local standard of rest to the galaxy's rest frame; meanwhile $\dot{M}$ of the cool and warm gas does not change significantly. Third, OVI and NV are promising ions to probe the Milky Way's outer CGM ($r\gtrsim$15 kpc), but CIV may be less sensitive. Lastly, the scatter in ion column density is a factor of 2 higher if the CGM is observed from inside-out than from external views because of the gas radial density profile. Our work highlights that observations of the Milky Way's CGM, especially those using HI 21cm and QSO absorption lines, are highly biased. We demonstrate that these biases can be quantified and calibrated through synthetic observations with simulated Milky-Way analogs.

 Material. 50 workers from 2 nests, Spain, Sierra de Cazorla (Jaén), 26.IX.2020, 37°48’48.1”N 2°57’36.6”W, 1796m.
 Diagnosis. Characterized within the Iberian sordidulus species-complex by its dark brown coloration, extremely elongated head (mean HL/HWb 1.318), whole surface of head and mesosoma reticulated, inconspicuous to shallowly-impressed metanotal groove (mean MGr/CS 0.485%), moderately long propodeal spines (mean SPST/CS 0.267) and long mesosoma (mean ML/CS 1.310). Larger species in the sordidulus species-complex (CS mean 0.644 mm).
 Comments. It is readily separated from darker forms of T. tergestinus by its long head and less developed metanotal groove, from T. ibericus by the reticulated sculpture of head, poorly developed metanotal groove and narrow postpetiole, from T. sordidulus by its long head and poorly developed metanotal groove, and from T. estel sp. nov. by the different coloration pattern and shorter propodeal spines. Temnothorax platycephalus is most similar to T. conatensis, from which it is differentiated by its longer head and shorter propodeal spines, sharing the characteristic shape of petiole and robust appearance. Nests are monogynous and located in rock crevices at high altitudes. The only known records are from Jaén and Cuenca (Espadaler 1997).

description: This study examines whether term structure can be used as a predictor of commodity price direction. It uses daily prices for the S&P GSCI and each of the 24 underlying commodities from January 2007 through December 2013. During each day of the monthly roll period, one-month returns for each commodity are calculated and compared with the corresponding term structure. In nearly all cases, the relationship between returns and term structure is no different from that of a random process. Mean returns for each commodity under backwardation-only and contango-only are examined and in most cases are not significantly different from zero. A detailed examination of unleaded gasoline finds that returns on a long position are little affected by term structure, but heavily affected by the price trend in the underlying market.

description: In this paper, explicit method of constructing approximations (the Triangle Entropy Method) is developed for nonequilibrium problems. This method enables one to treat any complicated nonlinear functionals that fit best the physics of a problem (such as, for example, rates of processes) as new independent variables. The work of the method was demonstrated on the Boltzmann's--type kinetics. New macroscopic variables are introduced (moments of the Boltzmann collision integral, or scattering rates). They are treated as independent variables rather than as infinite moment series. This approach gives the complete account of rates of scattering processes. Transport equations for scattering rates are obtained (the second hydrodynamic chain), similar to the usual moment chain (the first hydrodynamic chain). Various examples of the closure of the first, of the second, and of the mixed hydrodynamic chains are considered for the hard spheres model. It is shown, in particular, that the complete account of scattering processes leads to a renormalization of transport coefficients. The method gives the explicit solution for the closure problem, provides thermodynamic properties of reduced models, and can be applied to any kinetic equation with a thermodynamic Lyapunov function.

description: In 1974, Gehring posed the problem of minimizing the length of two linked curves separated by unit distance. This constraint can be viewed as a measure of thickness for links, and the ratio of length over thickness as the ropelength. In this paper we refine Gehring's problem to deal with links in a fixed link-homotopy class: we prove ropelength minimizers exist and introduce a theory of ropelength criticality. Our balance criterion is a set of necessary and sufficient conditions for criticality, based on a strengthened, infinite-dimensional version of the Kuhn--Tucker theorem. We use this to prove that every critical link is C^1 with finite total curvature. The balance criterion also allows us to explicitly describe critical configurations (and presumed minimizers) for many links including the Borromean rings. We also exhibit a surprising critical configuration for two clasped ropes: near their tips the curvature is unbounded and a small gap appears between the two components. These examples reveal the depth and richness hidden in Gehring's problem and our natural extension.

description: Using daily prices from 134 corn cash markets from seven Midwestern states, this study examines the increase in short-run cash price forecasting accuracy provided by augmenting futures prices with recent observations from other cash markets. We utilize a Granger-causality-based criterion to determine the structure of the augmented models, i.e. how far to look for potentially relevant forecast information. For about 65% of the markets, the model consisting of prices of the futures market, the specific cash market, and its nearby cash markets (M2) forecasts better than the one only incorporating prices of the futures market and the specific cash market (M1) for five-, ten-, and thirty-day ahead forecasts based on root mean squared error (RMSE). For short-run forecasts, RMSEs tend not to be significantly different for most of the cash markets investigated, suggesting that the forecast accuracy improvement from including nearby cash markets is only moderate. However, the expanded model (M2) tends to significantly outperform the bivariate model (M1) more often as the forecast horizon increases.

description: Tidal forces in eccentric binary stars known as heartbeat stars excite detectable oscillations that shed light on the processes of tidal synchronization and circularization. We examine the pulsation phases of tidally excited oscillations (TEOs) in heartbeat binary systems. The target list includes four published heartbeat binaries and four additional systems observed by {\it Kepler}. To the first order, the pulsation phases of TEOs can be explained by the geometric effect of the dominant $l=2$, $m=0$, or $\pm 2$ modes assuming pulsations are adiabatic. We found that this simple theoretical interpretation can account for more than half of the systems on the list, assuming their spin and orbit axes are aligned. We do find significant deviations from the adiabatic predictions for some other systems, especially for the misaligned binary KIC 8164262. The deviations can potentially help to probe the non-adiabaticity of pulsation modes as well as resonances in the tidal forcing.

description: Crop producers’ hedging behavior is at odds with the optimal hedging under expect utility theory. However, there is little consensus on how producers hedge otherwise. In this paper we present an intriguing empirical observation using the Commitment of Traders reports (COT) published by Commodity Futures Trading Commission (CFTC), which shows the hedging behavior of corn and soybean producers may be reference-dependent. We show that producers are likely to hedge when the futures price rises above a reference. Though this reference varies among producers, on the aggregate level, last year’s average price and 20-trading-day moving average of the current futures price are likely candidates. We also discuss the limitation of the data as well as the identification strategies.

description: This study assessed in situ stabilization combined with phytoexclusion in practical application on agricultural land contaminated strongly, and spatially heterogeneous, with metals (Cd, Pb, and Zn) and As. Single and combined lime marl and phosphate treatments were consecutively planted with two cultivars each of rape, wheat, and barley differing in trace elements (TE) accumulation. The effects on soil acidity, NH4NO3-soluble, and straw and grain TE concentrations were evaluated. The combined fertilizer treatment most effectively reduced metals mobility, but neither amendment mitigated plant TE status, which correlated more with pseudo-total than NH4NO3-soluble TE in soil. The cultivar choice reduced grain Cd by 39 or 21% in barley or wheat, respectively, simultaneously decreased grain Zn, but conversely affected As uptake in wheat grains. The lack of correlations between grain TE concentrations suggests the potential for breeding cultivars with low Cd and As accumulation without causing Zn malnutrition. The cereals had relatively low yields, particularly on highly polluted areas, and only rape and barley grains unexceptionally suited for animal consumption. Agricultural measures and climatic conditions influenced TE mobility. The cultivars’ TE uptake varied less than in greenhouse studies, stressing the importance of field studies for an adequate estimation of phytoexclusion potentials.

description: In this paper, we investigate the term structure of agricultural commodity prices. Using corn as an example, we demonstrate that commodity futures price curve can be wellapproximated by three latent factors: level, slope, and curvature obtained from a dynamic latent factor model. Relating the three unobserved factors to observable economic fundamentals, we find that real economic activity and relative scarcity of the commodity play an important role in the evolution of the corn futures price curve. Using Granger causality tests, we find that all three unobserved factors of the futures price curve contain predictive information on real economic activity and the relative scarcity of the commodity. Consistent with the theory of storage, there is a forwardlooking element embedded in the term structure of commodity prices that contain information regarding subsequent market fundamentals.

description: Pedestrian detection methods have been significantly improved with the development of deep convolutional neural networks. Nevertheless, detecting small-scaled pedestrians and occluded pedestrians remains a challenging problem. In this paper, we propose a pedestrian detection method with a couple-network to simultaneously address these two issues. One of the sub-networks, the gated multi-layer feature extraction sub-network, aims to adaptively generate discriminative features for pedestrian candidates in order to robustly detect pedestrians with large variations on scales. The second sub-network targets in handling the occlusion problem of pedestrian detection by using deformable regional RoI-pooling. We investigate two different gate units for the gated sub-network, namely, the channel-wise gate unit and the spatio-wise gate unit, which can enhance the representation ability of the regional convolutional features among the channel dimensions or across the spatial domain, repetitively. Ablation studies have validated the effectiveness of both the proposed gated multi-layer feature extraction sub-network and the deformable occlusion handling sub-network. With the coupled framework, our proposed pedestrian detector achieves state-of-the-art results on the Caltech and the CityPersons pedestrian detection benchmarks.

description: The price relationships governing dairy commodity price transmission among the U.S., Oceania, and EU markets are considered using Vector Autoregressive and Vector Error Correction models. Results demonstrate a one-way price relationship for U.S. dry milk powders as price shocks in Oceania and the European Union spread to the U.S. while U.S. price shocks do not spread into those markets. U.S. prices for cheddar and butter are impacted by price shocks in Oceania and the EU, however, U.S. price shocks also spread the Oceania market and may reflect potential arbitrage opportunities. Historically thought to be shielded from international prices through low import quotas and high out-of-quota tariffs these results are the first to empirically demonstrate that U.S. dairy commodity prices and farm-gate milk prices are influenced in both the long-run and short run by international dairy commodity prices.

description: A battery is a classical apparatus which converts a chemical reaction into a persistent voltage bias able to power electronic circuits. Similarly, a phase battery is a quantum equipment which provides a persistent phase bias to the wave function of a quantum circuit. It represents a key element for quantum technologies based on quantum coherence. Unlike the voltage batteries, a phase battery has not been implemented so far, mainly because of the natural rigidity of the quantum phase that, in typical quantum circuits, is imposed by the parity and time-reversal symmetry constrains. Here we report on the first experimental realization of a phase battery in a hybrid superconducting circuit. It consists of an n-doped InAs nanowire with unpaired-spin surface states and proximitized by Al superconducting leads. We find that the ferromagnetic polarization of the unpaired-spin states is efficiently converted into a persistent phase bias $φ_0$ across the wire, leading to the anomalous Josephson effect. By applying an external in-plane magnetic field a continuous tuning of $φ_0$ is achieved. This allows the charging and discharging of the quantum phase battery and reveals the symmetries of the anomalous Josephson effect predicted by our theoretical model. Our results demonstrate how the combined action of spin-orbit coupling and exchange interaction breaks the phase rigidity of the system inducing a strong coupling between charge, spin and superconducting phase. This interplay opens avenues for topological quantum technologies, superconducting circuitry and advanced schemes of circuit quantum electrodynamics.}

description: Processing of conversations is a core technique in conversational AI. However, current speech recognition solutions, even the state-of-the-art systems, model a single, isolated utterance, not an entire conversation. These systems are therefore unable to use potentially important contextual information that spans across multiple utterances or speakers in a conversation. This thesis focuses
on designing an End-to-End speech recognition system that processes entire conversations. To achieve this goal, I propose three novel techniques: 1) an efficient way to preserve long conversational contexts by creating a context encoder that maps spoken utterance histories to a single
context vector; 2) an effective way to integrate conversational contexts into End-to-End models
using a gating mechanism; and 3) various methods to encode conversational contexts by using previously spoken utterances and augmenting with world knowledge using external linguistic resources (e.g. BERT, fastText). I show accuracy improvements with three different large corpora,
Switchboard (300 hours), Fisher (2,000 hours), and Medical conversation (1,700 hours), and share the analysis to demonstrate the effectiveness of my approach. This thesis will provide insight into designing conversational speech recognition systems and spoken language understanding
systems, which are becoming increasingly important as voice-driven device interfaces become mainstream.

description: Uniform fluid flow distribution in a symmetric volume can be realized through a symmetric branched tree. It is shown here, however, that the flow partitioning can be highly sensitive to deviations from exact symmetry if inertial effects are present. This is found by direct numerical simulation of the Navier-Stokes equations in a 3D tree geometry. The flow asymmetry is quantified and found to depend on the Reynolds number. Moreover, for a given Reynolds number, we show that the flow distribution depends on the aspect ratio of the branching elements as well as their angular arrangement. Our results indicate that physiological variability should be severely restricted in order to ensure uniform fluid distribution in a tree. This study suggests that any non-uniformity in the air flow distribution in human lungs should be influenced by the respiratory conditions, rest or hard exercise.
Qwind code release: a non-hydrodynamical approach to modelling line-driven winds in active galactic nuclei

description: Ultraviolet (UV) line driven winds may be an important part of the active galactic nucleus (AGN) feedback process, but understanding their impact is hindered by the complex nature of the radiation hydrodynamics. Instead, we have taken the approach pioneered by Risaliti & Elvis, calculating only ballistic trajectories from radiation forces and gravity, but neglecting gas pressure. We have completely re-written their QWIND code using more robust algorithms, and can now quickly model the acceleration phase of these winds for any AGN spectral energy distribution spanning UV and X-ray wavebands. We demonstrate the code using an AGN with black hole mass $10^8\, M_\odot$ emitting at half the Eddington rate and show that this can effectively eject a wind with velocities $\simeq (0.1-0.2)\, c$. The mass loss rates can be up to $\simeq 0.3 M_\odot$ per year, consistent with more computationally expensive hydrodynamical simulations, though we highlight the importance of future improvements in radiation transfer along the multiple different lines of sight illuminating the wind. The code is fully public, and can be used to quickly explore the conditions under which AGN feedback can be dominated by accretion disc winds.
