description: Magnetohydrodynamic (MHD) simulations have been used to study disk accretion to a rotating magnetized star with an aligned dipole moment. Quiescent initial conditions were developed in order to avoid the fast initial evolution seen in earlier studies. A set of simulations was performed for different stellar magnetic moments and rotation rates. Simulations have shown that the disk structure is significantly changed insidea radius r_{br} where magnetic braking is significant. In this region the disk is strongly inhomogeneous. Radial accretion of matter slows as it approaches the area of strong magnetic field and a dense ring and funnel flow form at the magnetospheric radius r_m where the magnetic pressure is equal to the total, kinetic plus thermal, pressure of the matter.

description: In this paper, we give formal results of Schwinger pair production correction in thermal systems with external background field by using the evolution operator method of thermo field dynamics, where especially tree level correction of thermal photons is considered with linear response approaches by an effective mass shift. We consider initial systems in two types of vacuums as zero temperature and thermal vacuum, respectively, with correction of thermal photons is or not included. As an example we give results of these corrections to pair production for a constant external background electric field.

description: We provide a novel analysis of low-rank tensor completion based on hypergraph expanders. As a proxy for rank, we minimize the max-quasinorm of the tensor, which generalizes the max-norm for matrices. Our analysis is deterministic and shows that the number of samples required to approximately recover an order-$t$ tensor with at most $n$ entries per dimension is linear in $n$, under the assumption that the rank and order of the tensor are $O(1)$. As steps in our proof, we find a new expander mixing lemma for a $t$-partite, $t$-uniform regular hypergraph model, and prove several new properties about tensor max-quasinorm. To the best of our knowledge, this is the first deterministic analysis of tensor completion. We develop a practical algorithm that solves a relaxed version of the max-quasinorm minimization problem, and we demonstrate its efficacy with numerical experiments.

description: A new generation of parton distribution functions with increased precision and quantitative estimates of uncertainties is presented. This work significantly extends previous CTEQ and other global analyses on two fronts: (i) a full treatment of available experimental correlated systematic errors for both new and old data sets; (ii) a systematic and pragmatic treatment of uncertainties of the parton distributions and their physical predictions, using a recently developed eigenvector-basis approach to the Hessian method. The new gluon distribution is considerably harder than that of previous standard fits. A number of physics issues, particularly relating to the behavior of the gluon distribution, are addressed in more quantitative terms than before. Extensive results on the uncertainties of parton distributions at various scales, and on parton luminosity functions at the Tevatron RunII and the LHC, are presented. The latter provide the means to quickly estimate the uncertainties of a wide range of physical processes at these high-energy hadron colliders, based on current knowledge of the parton distributions. In particular, the uncertainties on the production cross sections of the $W,Z$ at the Tevatron and the LHC are estimated to be $\pm 4%$ and $\pm 5%$ respectively, and that of a light Higgs at the LHC to be $\pm 5%$.

description: As the ungual phalanges of tetrapods are the first structures that interact with the substrate, studying them is of great importance when wanting to know the locomotor behaviour of different species. In this work, we analyse the ungual phalanges of the third finger from the manus of several Pleistocene sloths: G. robustum, L. armatus, M. jeffersonii, M. americanum, S. leptocephalum; and of a wide range of extant xenarthrans and other mammals. The third finger of the manus was chosen because of its larger size and nearly perfect bilateral symmetry, which enhances the possibility to observe functional differences between taxa. The analysis performed on them were of the inner and external curvature and the finite element method. By comparing the results obtained for the fossils and the extant species we were able to indicate possible habits for these Pleistocene ground sloths. Through these analyses the three mylodontid sloths: G. robustum, L. armatus and S. leptocephalum showed a preference for strenuous activities such as digging. On the contrary, M. jeffersonii and M. americanum, although they showed similar resistant structures, they learned more towards a less specific locomotor habit, such as generalised terrestrial mammals.

description: The goal of this short note is to study the secant varieties of the triple Segre product of type (1,a,b) by means of the standard tools of combinatorial commutative algebra. We reprove and extend to arbitrary characteristic results of Landsberg and Weyman regarding the defining ideal and the Cohen-Macaulay property of the secant varieties. Furthermore for these varieties we compute the degree and give a bound for their Castelnuovo-Mumford regularity which is sharp in many cases.

description: We present subarcsecond resolution mid infrared images of NGC 4151 at 10.8 micron and 18.2 micron. These images were taken with the University of Florida mid-IR camera/spectrometer OSCIR at the Gemini North 8-m telescope. We resolve emission at both 10.8 micron and 18.2 micron extending ~ 3.5" across at a P.A. of ~ 60 degrees. This coincides with the the narrow line region of NGC 4151 as observed in [OIII] by the Hubble Space Telescope. The most likely explanation for this extended mid-IR emission is dust in the narrow line region heated by a central engine. We find no extended emission associated with the proposed torus and place an upper limit on its mid-IR size of less than or equal to ~ 35 pc.

description: We propose a simple tweak to a recently developed regularisation scheme for particle methods. This allows us to chose the particle spacing $h$ proportional to the regularisation length $σ$ and achieve optimal error bounds of the form $\mathcal{O}(σ^n)$, $n\in\mathbb{N}$, without any need of remeshing. We prove this result for the linear advection equation but also carry out high-order experiments on the full Navier--Stokes equations. In our experiments the particle methods proved to be highly accurate, long-term stable, and competitive with discontinuous Galerkin methods.
How did amber get its aquatic insects? Water-seeking polarotactic insects trapped by tree resin

description: Amber contains numerous well-preserved adult aquatic insects (e.g., aquatic beetles – Coleoptera, water bugs – Heteroptera, dragonflies – Odonata, caddisflies – Trichoptera, mayflies – Ephemeroptera, stone flies – Plecoptera). Since amber is fossilised resin of terrestrial conifer trees, it is an enigma how aquatic insects have ended up in the resin. Based on field studies in a Hungarian forest along a freshwater creek we suggest that tree resin traps water-seeking flying polarotactic aquatic insects because of its property to polarise reflected light. The sticky tree resin was modelled by a water-proof, transparent, colourless insect-monitoring glue laid on vertical and horizontal fallen tree trunks next to the creek. Adults of various polarotactic aquatic insect species were trapped only by the horizontal sticky trunk. In earlier field experiments we showed that these insects find water by means of the horizontal polarisation of water-reflected light, and therefore are attracted to and land on all surfaces which reflect horizontally polarised light. Using imaging polarimetry, we revealed the criterion of polarisation-based trapping by resiny tree trunks. According to our observations, flying aquatic insects can be trapped by sticky (resiny) regions of fallen tree trunks that reflect horizontally polarised light and thus attract polarotactic species. The resin continues to flow out of the trees even when fallen over or fractured in a storm. Our findings support and complement an earlier hypothesis, according to which amber-preserved adult aquatic insects have been trapped by resiny bark when they dispersed over land.

The obtained charge density clearly revealed the covalent bonding feature of boron forming the 2D honeycomb network in the basal plane, on the other hand, Mg is found to be in divalent state. A subtle but clear charge concentration was found on boron 2D sheets at 15K, which should be relating to superconductivity.

description: Three-dimensional (3D) simulations of electron beams propagating in high energy density (HED) plasmas using the quasi-static Particle-in-Cell (PIC) code QuickPIC demonstrate a significant increase in stopping power when beam electrons mutually interact via their wakes. Each beam electron excites a plasma wave wake of wavelength $\sim2πc/ω_{pe}$, where $c$ is the speed of light and $ω_{pe}$ is the background plasma frequency. We show that a discrete collection of electrons undergoes a beam-plasma like instability caused by mutual particle-wake interactions that causes electrons to bunch in the beam, even for beam densities $n_b$ for which fluid theory breaks down. This bunching enhances the beam's stopping power, which we call "correlated stopping," and the effect increases with the "correlation number" $N_b \equiv n_b (c/ω_{pe})^3$. For example, a beam of monoenergetic 9.7 MeV electrons with $N_b=1/8$, in a cold background plasma with $n_e=10^{26}$ cm$^{-3}$ (450 g cm$^{-3}$ DT), has a stopping power of $2.28\pm0.04$ times the single-electron value, which increases to $1220\pm5$ for $N_b=64$. The beam also experiences transverse filamentation, which eventually limits the stopping enhancement.

description: The aim of this systematic review and meta-analysis was to examine and assess the basic demographic characteristics and prevalence of comorbidities in acute mesenteric ischemia (AMI) and its various subtypes. A literature search was conducted by using the databases PubMed, EMBASE, and Google Scholar (to June 1, 2022). Random-effects or fixed-effects models were selected to pool means and proportions and their corresponding 95% confidence intervals (CI), based on heterogeneity between studies. The results of meta-analyses for basic demographic characteristics and prevalence (proportions) of each specific comorbidities of acute mesenteric ischemia (AMI) and its various subtypes were described. Ninety-nine studies were included in the meta-analysis, including 17,103 patients with AMI. Furthermore, 7941 patients with subclass diagnoses of AMI were identified, including 3,239 patients with arterial occlusive mesenteric ischemia (AOMI), 2,977 patients with nonocclusive mesenteric ischemia (NOMI), and 1,725 patients with mesenteric venous thrombosis (MVT). As a surgical emergency, AMI is associated with older patients and a high likelihood of multisystem comorbidities. Comorbidities of AMI involved multiple systemic diseases, including cardiovascular disease, endocrine and metabolic diseases, kidney diseases, digestive diseases, respiratory diseases, cerebrovascular diseases, vascular diseases, and cancer. The basic demographic characteristics and the prevalence of comorbidities of different subtypes of AMI are different. The management of comorbidities should be an essential part of improving the prognosis of AMI patients and may contribute to precise prevention of AMI.

description: Numerical solutions of the Einstein-Yang-Mills equations with a negative cosmological constant are constructed. These axially symmetric solutions approach asymptotically the anti-de Sitter spacetime and are regular everywhere. They are characterized by the winding number $n>1$, the mass and the non-Abelian magnetic charge. The main properties of the solutions and the differences with respect to the asymptotically flat case are discussed. The existence of axially symmetric monopole and dyon solutions in fixed anti-de Sitter spacetime is also discussed.

The Rate of Planet-star Coalescences Due to Tides and Stellar Evolution

Year: 2019
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Orbits of close-in planets can shrink significantly due to dissipation of tidal energy in a host star. This process can result in star-planet coalescence within the Galactic lifetime. In some cases, such events can be accompanied by an optical or/and UV/X-ray transient. Potentially, these outbursts can be observed in near future with new facilities such as LSST from distances about few Mpc. We use a population synthesis model to study this process and derive the rate of star-planet mergers of different types. Mostly, planets are absorbed by red giants. However, these events, happening with the rate about 3 per year, mostly do not produce detectable transients. The rate of mergers with main sequence stars depends on the effectiveness of tidal dissipation; for reasonable values of stellar tidal quality factor, such events happen in a Milky Way-like galaxy approximately once in 70 yrs or more rarely. This rate is dominated by planets with low masses. Such events do not produce bright transients having maximum luminosities $\lesssim 10^{36.5}$erg s$^{-1}$. Brighter events, related to massive planets, with maximum luminosity $\sim 10^{37.5}$--$10^{38}$erg s$^{-1}$, have the rate nearly five times smaller.

description: The 2003 Common Agricultural Policy (CAP) reform radically changes the way the European Union (EU) supports its agricultural sector by decoupling direct payments. Production is no longer required to get the payment attached to Single Farm Payment (SFP) entitlements. However, the new scheme maintains a specific link between payments and hectares; in addition, SFP entitlements can be exchanged among farmers. These features question the way SFP entitlements should be regarded, hence modelled, i.e., as lump-sum transfers, area payments or… something else. We develop a microeconomic analytical framework which shows that the answer crucially depends on the total number of entitlements which are initially made available relative to the number of hectares, more specifically the number of cultivated hectares in a zero support regime, the number of cultivated hectares in a policy support regime trough per-hectare direct aids, and the number of cultivated or idled hectares in a policy regime where support is granted through direct aids per hectare and production is not required.

description: Based on a conceptual framework, we develop the hypothesis that part-time farmers invest in less profitable products than full-time farms, due to the necessary minimum labour requirements which entering and running profitable production processes require. Descriptive statistics for Swiss farms show some indications for this hypothesis, like a much lower total revenue and lower agricultural income of part-time farms, despite a comparable value of the farm’s assets. A regression analysis for the period 1996-2005 confirms that Swiss part-time farms tend to focus on products with low labour profitability. This may explain why part-time farming in Switzerland is less developed than in most other European countries, and raises the question whether part-time farming offers a solution for structural change process in small-structured agricultural systems affected by imperfections on factor markets.
Percolation and depinning transitions in cut-and-paste models of adaptation

description: We show that a cut-and-paste model to mimic a trial-and-error process of adaptation displays two pairs of percolation and depinning transitions, one for persistence and the other for efficiency. The percolation transition signals the onset of a property and the depinning transition, the growth of the same property. Despite its simplicity, the cut-and-paste model is qualitatively the same as the Minority Game. A majority cut-and-paste model is also introduced, to mimic the spread of a trend. When both models are iterated, the majority model reaches a frozen state while the minority model converges towards an alternate state. We show that a transition from the frozen to the alternate state occurs in the limit of a non-adaptive system.

description: Most of the European Union’s (EU) import sources for rice are in developing countries and the least-developed countries (LDCs). The EU has moreover made a commitment to allow duty-free and quota-free access to rice imports originating in the LDCs from September 2009 onward. The purpose of this article is to answer two questions – First: Does the inclusion of import tariffs in the specification lead to different estimated Armington elasticities? Second: When a discriminating tariff is introduced, what happens to the market share of large rice exporters to the EU, especially to the market share of poor countries? Consequently, we present the Armington model, derived from a constant elasticity of substitution (CES) utility function, and a non-homothetic CES utility functional form, which is more flexible. Then, we estimate the Armington model, with and without the inclusion of a tariff, and we compare the elasticities. Lastly, we model five scenarios with different discriminating import tariff rates to calculate the changes in the market access of large rice exporters to the EU. Our empirical results show that it is worthwhile to consider non-homothetic preferences and import tariffs. When the model is estimated, ignoring the import tariffs and the non-homothetic parameter, results may be biased and of uncertain validity. Furthermore the simulation findings demonstrate that in spite of a large difference between import tariff rate of Suriname and other countries (scenario V), its market access would not change greatly. This may be caused by supply side problems like poor infrastructures, weak technology and small capacity production in LDCs

description: We investigate the fueling and the feedback of nuclear activity in the Seyfert 2 galaxy NGC1068, by studying the distribution and kinematics of molecular gas in the torus and its connections. We use ALMA to image the emission of a set of molecular gas tracers in the circumnuclear disk (CND) and the torus of the galaxy using the CO(2-1), CO(3-2) and HCO+(4-3) lines with spatial resolutions ~0.03"-0.09"(2-6pc). ALMA resolves the CND as an asymmetric ringed disk of D~400pc-size and mass of ~1.4x10^8 Msun. The inner edge of the ring is associated with edge-brightened arcs of NIR polarized emission identified with the working surface of the AGN ionized wind. ALMA proves the existence of a molecular torus of M_torus ~ 3x10^5Msun, which extends over a large range of spatial scales D=10-30pc around the central engine. The new observations evidence the density radial stratification of the torus: the HCO+(4-3) torus, with a full size D=11pc, is a factor of 2-3 smaller than its CO(2-1) and CO(3-2) counterparts, which have full-sizes D=26pc and D=28pc, respectively. The torus is connected to the CND through a network of gas streamers. The kinematics of molecular gas show strong departures from circular motions in the torus, the gas streamers, and the CND. These velocity distortions are interconnected and are part of a 3D outflow that reflects the effects of AGN feedback on the kinematics of molecular gas across a wide range of spatial scales. We conclude that a wide-angle AGN wind launched from the accretion disk is impacting a sizeable fraction of the gas inside the torus (~0.4-0.6 x M_torus). However, a large gas reservoir (~1.2-1.8 x 10^5Msun) close to the equatorial plane of the torus remains unaffected by the AGN wind and can continue fueling the AGN for ~1-4Myr. AGN fueling seems nevertheless thwarted on intermediate scales (15pc < r < 50pc).

description: Abstract: Therapeutic development and drug discovery processes are heavily challenged by delays in the preclinical experimental stages before being offered for Phase 1 clinical trials. Virtual Embryo-like approaches, stem cell technologies, and cutting-edge computational models offer promising future tools (Shafique, 2018) [Fig. 3]. ZV infection results in pathological/morphological changes in the developing brain (Shafique, 2018a) resulting in the birth defect of microcephaly with immense psychosocial impact (Shafique, 2017a). The brain organoids have multiple applications including investigating developmental biology modeling neurodevelopmental defects such as microcephaly (Lancaster et al., 2013) [Fig 1,2]. More specialized region-specific organoids of brain regions such as the forebrain organoid platform to model Zika virus (ZIKV) exposure have been developed (Qian et al., 2017) [Fig. 4,5]. This forebrain-focused organoid model is a renewable, easily available, and economically novel tool to evaluate and screen for therapeutic drugs, such as antiviral compounds, and determine their efficacy and safety for the phase 1 clinical trials. This poster is an overview encompassing the currently available options for preclinical developmental toxicity testing with a focus on the potential applications of 3D organoids in context with investigating Zika virus-related domains. These sustainable, accessible, and renewable tools could help the researchers to replace the use of animal models for the purposes of toxicity testing during the drug development process.

Hoop conjecture for colliding black holes : non-time-symmetric initial data

description: The hoop conjecture is well confirmed in momentarily static spaces, but it has not been investigated systematically for the system with relativistic motion. To confirm the hoop conjecture for non-time-symmetric initial data, we consider the initial data of two colliding black holes with momentum and search an apparent horizon that encloses two black holes. In testing the hoop conjecture, we use two definitions of gravitational mass : one is the ADM mass and the other is the quasi-local mass defined by Hawking. Although both definitions of gravitational mass give fairly consistent picture of the hoop conjecture, the hoop conjecture with the Hawking mass can judge the existence of an apparent horizon for wider range of parameters of the initial data compared to the ADM mass.

description: The impact of the introduction of EU Single Area Payments (SAP) on farm expansion strategy in Lithuania is investigated, utilizing farm accounting and survey data. The introduction of the SAP has a positive influence on farmers’ intentions to expand their area compared to a baseline scenario of the hypothetical continuation of pre-accession policy. The switch in policy has a more pronounced effect on farms that were previously credit constrained. While the SAP has been presented as a support that is decoupled from production, its introduction may have ex post coupled effects, through an income multiplier effect on credit constrained farmers

description: We present an analysis of BeppoSAX observations of the IC1262 galaxy cluster and report the first temperature and abundance measurements, along with preliminary indications of diffuse, nonthermal emission. By fitting a 6' (~360 h_50^-1 kpc) region with a single Mewe-Kaastra-Liedahl model with photoelectric absorption, we find a temperature of 2.1 - 2.3 keV, and abundance of 0.45 - 0.77 (both 90% confidence). We find the addition of a power-law component provides a statistically significant improvement (F-test = 90%) to the fit. The addition of a second thermal component also improves the fit but we argue that it is physically implausible. The power-law component has a photon index (Gamma_X) of 0.4 - 2.8 and a nonthermal flux of (4.1 - 56.7) x 10-5 photons cm^-2 s^-1 over the 1.5 - 10.5 keV range in the Medium Energy Concentrator spectrometer detector. An unidentified X-ray source found in the ROSAT High Resolution Imager observation (~0'.9 from the center of the cluster) is a possible explanation for the nonthermal flux; however, additional evidence of diffuse, nonthermal emission comes from the NRAO VLA Sky Survey and the Westerbork Northern Sky Survey radio measurements, in which excess diffuse, radio flux is observed after point-source subtraction. The radio excess can be fitted to a simple power law with a spectral index of ~1.8, which is consistent with the nonthermal X-ray emission spectral index. The steep spectrum is typical of diffuse emission and the size of the radio source implies that it is larger than the cD galaxy and not due to a discreet source.

description: We present direct evidence for CO freeze-out in a circumstellar disk around the edge-on class I object CRBR 2422.8-3423, observed in the M band with VLT-ISAAC at a resolving power R~10,000. The spectrum shows strong solid CO absorption, with a lower limit on the column density of 2.2E18 cm-2. The solid CO column is the highest observed so far, including high-mass protostars and background field stars. Absorption by foreground cloud material likely accounts for less than 10% percent of the total solid CO, based on the weakness of solid CO absorption toward nearby sources and the absence of gaseous C18O J=2-1 emission 30'' south. Gas-phase ro-vibrational CO absorption lines are also detected with a mean temperature of 50 +/-10 K. The average gas/solid CO ratio is ~1 along the line of sight. For an estimated inclination of 20 +/- 5 degree, the solid CO absorption originates mostly in the cold, shielded outer part of the flaring disk, consistent with the predominance of apolar solid CO in the spectrum and the non-detection of solid OCN-, a thermal/ultraviolet processing of the ice mantle. The gaseous CO comes from the warm upper layers closer to the star.

description: Livelihood strategies in developing countries typically depend on agricultural activities. Nonetheless, climate change, recurrent droughts and floods are contributing to crop failures in many developing countries yet beekeeping has proven to offer a valuable adaptive strategy. Against this background, the study sought to examine the role of apiculture as an alternative livelihood strategy in Honde Valley. Using the feasible generalised least squares (FGLS) technique and cross sectional data collected on 80 households selected through multistage sampling technique, gender of household head, access to credit, dependency ratio, level of education and size of land owned are found to be significant factors explaining rural income in Honde Valley. Turning to the variable of enquiry, the results of the analysis of covariance (ANCOVA) indicate that the mean per capita income for apiculture farmers is found to be significantly higher than that of non-apiculture farmers. Against this background, apiculture can be used as an alternative livelihood for the rural community. The study contributes in identifying alternative livelihood strategies in developing countries like Zimbabwe.

description: This paper investigates unmanned aerial vehicle (UAV) data collection systems with different multiple access schemes, where a rotary-wing UAV is dispatched to collect data from multiple ground nodes (GNs). Our goal is to maximize the minimum UAV data collection throughput from GNs for both orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) transmission, subject to the energy budgets at both the UAV and GNs, namely \emph{double energy limitations}. 1) For OMA, we propose an efficient algorithm by invoking alternating optimization (AO) method, where each subproblem is alternately solved by applying successive convex approximation (SCA) technique. 2) For NOMA, we first handle subproblems with fixed decoding order using SCA technique. Then, we develop a penalty-based algorithm to solve the decoding order design subproblem. Numerical results show that: i) The proposed algorithms are capable of improving the max-min throughput performance compared with other benchmark schemes; and ii) NOMA yields a higher performance gain than OMA when GNs have sufficient energy.
