description: In this work we establish and test methods for implementing dynamical friction for massive black hole pairs that form in large volume cosmological hydrodynamical simulations which include galaxy formation and black hole growth. We verify our models and parameters both for individual black hole dynamics and for the black hole population in cosmological volumes. Using our model of dynamical friction (DF) from collisionless particles, black holes can effectively sink close to the galaxy center, provided that the black hole's dynamical mass is at least twice that of the lowest mass resolution particles in the simulation. Gas drag also plays a role in assisting the black holes' orbital decay, but it is typically less effective than that from collisionless particles, especially after the first billion years of the black hole's evolution. DF from gas becomes less than $1\%$ of DF from collisionless particles for BH masses $> 10^{7}$ M$_{\odot}$. Using our best DF model, we calculate the merger rate down to $z=1.1$ using an $L_{\rm box}=35$ Mpc$/h$ simulation box. We predict $\sim 2$ mergers per year for $z>1.1$ peaking at $z\sim 2$. These merger rates are within the range obtained in previous work using similar-resolution hydro-dynamical simulations. We show that the rate is enhanced by factor of $\sim 2$ when DF is taken into account in the simulations compared to the no-DF run. This is due to $>40\%$ more black holes reaching the center of their host halo when DF is added.

Transiting planets - lightcurve analysis for eccentric orbits

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: Transiting planet lightcurves have historically been used predominantly for measuring the depth and hence ratio of the planet-star radii, p. Equations have been previously presented by Seager & Mallen-Ornelas (2003) for the analysis of the total and trough transit lightcurve times to derive the ratio of semi-major axis to stellar radius, a/R*, in the case of circular orbits. Here, a new analytic model is proposed which operates for the more general case of an eccentric orbit. We aim to investigate three major effects our model predicts: i) the degeneracy in transit lightcurve solutions for eccentricity, e>0 ii) the asymmetry of the lightcurve and the resulting shift in the mid-transit time, Tmid iii) the effect of eccentricity on the ingress and egress slopes. It is shown that a system with changing eccentricity and inclination may produce a long period transit time variation (LTTV). Furthermore, we use our model in a reanalysis of HD 209458 b archived data by Richardson et al. (2006), where we include the confirmed non-zero eccentricity and derive a 24 micron planetary radius of R_P = 1.275 +- 0.082 R_J (where R_J = 1 Jovian radius), which is 1% larger than is we assume a circular orbit.

description: Terrestrial-satellite networks are envisioned to play a significant role in the sixth-generation (6G) wireless networks. In such networks, hot air balloons are useful as they can relay the signals between satellites and ground stations. Most existing works assume that the hot air balloons are deployed at the same height with the same minimum elevation angle to the satellites, which may not be practical due to possible route conflict with airplanes and other flight equipment. In this paper, we consider a TSN containing hot air balloons at different heights and with different minimum elevation angles, which creates the challenge of non-uniform available serving time for the communication between the hot air balloons and the satellites. Jointly considering the caching, computing, and communication (3C) resource management for both the ground-balloon-satellite links and inter-satellite laser links, our objective is to maximize the network energy efficiency. Firstly, by proposing a tapped water-filling algorithm, we schedule the traffic to relay among satellites according to the available serving time of satellites. Then, we generate a series of configuration matrices, based on which we formulate the relationship of relay time and the power consumption involved in the relay among satellites. Finally, the integrated system model of TSN is built and solved by geometric programming with Taylor series approximation. Simulation results demonstrate the effectiveness of our proposed scheme.

 Type locality. Colombia.
 Diagnosis. Males and females reddish-brown with conspicuous FW orange submarginal line. Examined males are distinguished from E. zolzivora and E. greeneyi by the thinner dorsal FW orange submarginal line, and the postmedial branch of this line that does not extend to the wing margin. The HW projection at Cu1 is intermediate in size: longer than E. zolzivora, but smaller than E. greeneyi. Thin lines always present ventrally in HW discal cell.
 Annotated redescription. Male. FW length 62 mm (n=1). Dorsal FW and HW with reddish-brown background and a faint pinkish iridescent sheen from submedial to postmedial areas of the FW, starting approximately at midlength of discal cell, and barely visible on HW. Dorsal FW with a well-defined, thin orange submarginal line, interrupted by small gaps below M3, and forming a V-shaped mark with the arms directed distally in cell M3. Submarginal branch of FW submarginal line starts in cell M2. Postmedial branch of submarginal line starts at cell M1. Dorsal FW and HW marginal outline well developed. HW projection at Cu1 present, extending beyond anal margin, but not as long or well defined as in E. greeneyi. Ventral FW and HW main color light brown. Ventral HW white postmedial transverse band well developed, continuous. Ventral HW with brown wavy lines across discal cell. Ventral HW eyespot in cell Sc+Rs outlined by a pale halo. Ventral HW eyespot in cell Cu1 large (smaller than E. zolzivora but larger than E. greeneyi) expanding to cell Cu2. Uncus humped, valva narrow, phallus prong displaced anteriorly from the distal opening.
 Female. Not available for examination.
 Distribution. Colombia (see comments on E. zolzivora in Frühstorfer 1912, Appendix 1), occurring in Cali at an elevation of ca. 1,000 m.
 Species status. Morphological differences between the Colombian E. opimus and the Bolivian E. zolzivora warrant species status. Male E. opimus differ from E. zolzivora in wing color and shape (compare Fig. 1G and I, see diagnoses). Furthermore, there are significant differences in male genitalia. The male valva is narrow in E. opimus, but in E. zolzivora it bears a large and distinctive subterminal swelling (compare Fig. 4G and I). This evidence supports the revised status for E. opimus as a separate species from E. zolzivora.

The simulations were carried out with a parametrized supernova type II shock front model (``$γ$ process'') of a 25 solar mass star and compared to recently published results. A decrease in the normalized overproduction factor could be attributed to lower cross sections of a significant fraction of seed nuclei located in the Bi and Pb region around the $N$=126 shell closure.

description: Solute transport through heterogeneous porous media is governed by fuid advection, molecular diffusion and anisotropic dispersion. The dispersion is assumed to obey Fick's law and the dispersion coefficient is defined as a second rank tensor. However, this problem has revealed to be a very difficult one because independently of the numerical methods employed, the solutions are seen to exhibit artificial oscillations and negative concentrations when the dispersivity becomes anisotropic. Here we report consistent SPH simulations of the anisotropic dispersion of a Gaussian contaminant plume in porous media using the open source code DualSPHysics. Consistency of the SPH method is restored by increasing the spatial resolution along with the number of neighbours within the compact support of the interpolating kernel. The solution shows that as the number of neighbours is increased with resolution, full convergence of the numerical solutions is guaranteed regardless of the dispersivity. However, despite the restored consistency, negative concentrations, albeit at a lower level, are still present. This suggests that a compromise between the number of neighbours and the size of the smoothing length must be guaranteed such that sufficient implicit numerical diffusion remains to damp out unphysical oscillations.
Appréhender le concept de performance : de la généralité au contexte portuaire

description: Le concept de performance fait l’objet, depuis plusieurs années, d’un intérêt croissant dans les recherches en management. Pris génériquement, dans les travaux en français comme en anglais, il y a de nombreuses avancées sur sa définition. Toutefois, malgré les progrès observés, la définition et l’évaluation du concept ne font l’objet que d’un consensus partiel. Aussi, lorsque le concept de performance est rapporté au contexte portuaire, il existe une absence criarde de travaux en langue française qui tentent de l’appréhender et de l’évaluer. Ainsi, l’article se donne pour but de chercher à comprendre le concept de performance plus particulièrement la performance portuaire. Pour ce faire, l’étude s’appuie sur la littérature pertinente en management portuaire. Les résultats indiquent, principalement, que, dans le contexte portuaire, la performance est un concept à double dimension à savoir l’efficience et l’efficacité. Ces deux dimensions permettent d’appréhender les activités portuaires aussi bien du point de vue des producteurs que des utilisateurs.

description: The newly discovered iron-based superconductors have attracted lots of interests, and the corresponding theoretical studies suggest that the system should have six bands. In this paper, we study the multiband effects on the conductivity based on the exact solutions of one-dimensional two-band Hubbard model. We find that the orbital degree of freedom might enhance the critical value $U_c$ of on-site interaction of the transition from a metal to an insulator. This observation is helpful to understand why undoped High-$T_c$ superconductors are usually insulators, while recently discovered iron-based superconductors are metal. Our results imply that the orbital degree of freedom in the latter cases might play an essential role.

description: We construct a non-relativistic limit of ten-dimensional N=1 supergravity from the point of view of the symmetries, the action, and the equations of motion. This limit can only be realized in a supersymmetric way provided we impose by hand a set of geometric constraints, invariant under all the symmetries of the non-relativistic theory, that define a so-called `self-dual' Dilatation-invariant String Newton-Cartan geometry. The non-relativistic action exhibits three emerging symmetries: one local scale symmetry and two local conformal supersymmetries. Due to these emerging symmetries the Poisson equation for the Newton potential and two partner fermionic equations do not follow from a variation of the non-relativistic action but, instead, are obtained by a supersymmetry variation of the other equations of motion that do follow from a variation of the non-relativistic action. We shortly discuss the inclusion of the Yang-Mills sector that would lead to a non-relativistic heterotic supergravity action.

description: We perform a three-dimensional general relativistic radiation magnetohydrodynamics simulation of a tilted super-Eddington accretion disk around the spinning black hole (BH). The disk, that tilts and twists as it approaches the BH, precesses while maintaining its shape. The gas is mainly ejected around the rotation axis of the outer part of the disk rather than around the spin axis of the BH. The disk precession changes the ejection direction of the gas with time. The radiation energy is also released in approximately the same direction as the outflow, so the precession is expected to cause a quasi-periodic time-variation of the observed luminosity. The timescale of the precession is about $10$ s for the 10 solar mass BH and for the radial extent of the disk of several tens of gravitational radii. This timescale is consistent with the frequency of the low-frequency quasi-periodic oscillation ($0.01-1$ Hz) observed in some ultraluminous X-ray sources.

description: We consider the problem of determining the proportion of edges that are discovered in an Erdos-Renyi graph when one constructs all shortest paths from a given source node to all other nodes. This problem is equivalent to the one of determining the proportion of edges connecting nodes that are at identical distance from the source node. The evolution of this quantity with the probability of existence of the edges exhibits intriguing oscillatory behavior. In order to perform our analysis, we introduce a new way of computing the distribution of distances between nodes. Our method outperforms previous similar analyses and leads to estimates that coincide remarkably well with numerical simulations. It allows us to characterize the phase transitions appearing when the connectivity probability varies.

In order to find the parameter $p$ that fixes with observations, we compute the cosmological parameters $A_S$, $n_S$, and $r$ for several values of $p\simeq 1$. We have found that the value of $p=1.0004$ reproduces the value of $A_S$, $n_\sca$, and $r$ in agreement with current observational data.

description: We consider, in general terms, the possible parameter space of thermal dark matter candidates. We assume that the dark matter particle is fundamental and was in thermal equilibrium in a hidden sector with a temperature $T'$, which may differ from that of the Standard Model temperature, $T$. The candidates lie in a region in the $T'/T$ vs. $m_{\rm dm}$ plane, which is bounded by both model-independent theoretical considerations and observational constraints. The former consists of limits from dark matter candidates that decoupled when relativistic (the relativistic floor) and from those that decoupled when non-relativistic with the largest annihilation cross section allowed by unitarity (the unitarity wall), while the latter concerns big bang nucleosynthesis ($N_{\rm eff}$ ceiling) and free streaming. We present three simplified dark matter scenarios, demonstrating concretely how each fits into the domain.

description: The current dominant paradigm for robotic manipulation involves two separate stages: manipulator design and control. Because the robot's morphology and how it can be controlled are intimately linked, joint optimization of design and control can significantly improve performance. Existing methods for co-optimization are limited and fail to explore a rich space of designs. The primary reason is the trade-off between the complexity of designs that is necessary for contact-rich tasks against the practical constraints of manufacturing, optimization, contact handling, etc. We overcome several of these challenges by building an end-to-end differentiable framework for contact-aware robot design. The two key components of this framework are: a novel deformation-based parameterization that allows for the design of articulated rigid robots with arbitrary, complex geometry, and a differentiable rigid body simulator that can handle contact-rich scenarios and computes analytical gradients for a full spectrum of kinematic and dynamic parameters. On multiple manipulation tasks, our framework outperforms existing methods that either only optimize for control or for design using alternate representations or co-optimize using gradient-free methods.

BIOLOGICAL CONTROL MEASURES AGAINST ROOT DISEASES IN LAVENDER (LAVANDULA ANGUSTIFOLIA)
Creators: name: To'laganova, N.B.
Publisher: name: Zenodo
Year: 2025

description: The research identifies root diseases in Lavandula angustifolia (lavender) while evaluating natural biological controls instead of traditional chemical fungicides. The availability of essential oils from Lavender along with its medicinal properties makes the plant vulnerable to Fusarium spp., Rhizoctonia solani, Pythium spp., and Verticillium spp. soil-borne pathogens. Soil-born pathogens result in root rot, growth impairment, and plant death and this leads to substantial yield decrease with concurrently diminished quality. This research examines Trichoderma harzianum along with Bacillus subtilis and Pseudomonas fluorescens biological agents since these microorganisms demonstrate their pathogenic inhibition abilities through antibiosis and parasitic and competitive exclusion methods in order to prevent environmental chemical treatment risks. The paper discusses three complementary agricultural methods including compost application along with crop rotation and bio-fumigation within integrated disease control systems.

Influence of spacing and artificial pruning on the production of clearwood of Douglas-fir
Creators: name: Reeb, Dominique
Publisher: name: University of British Columbia
Year: 2010

description: Analysis of markets for Douglas-fir has shown that clearwood will probably command high values in the future. To evaluate the demand for high quality wood a review of spacing and artificial pruning techniques was made. Their effects on wood quality were also studied. Results of research conducted at the U.B.C. Research Forest and at Wind River, U.S.A. in the Gifford Pinchot National Forest are presented in order to define some relationships among spacing, branch morphology, tree growth and natural pruning. Times required to prune branches by various techniques were analysed. Results were incorporated in a simulation model PRUNE to estimate the volumes and costs of clearwood produced by various pruning methods. It now appears that early pruning of widely spaced Douglas-fir will show the highest return on investment. New data are needed, however, to determine any extra costs of stand tending and to quantify the savings in establishment costs associated with wide spacings. In order to define optimum strategies for Coastal Douglas-fir, analyses should be made of the sensivity of benefits from pruning to various cost and premium structures for sites likely to be managed intensively.

description: We present a framework for understanding the recently observed cascade transitions and the Landau level degeneracies at every integer filling of twisted bilayer graphene. The Coulomb interaction projected onto narrow bands causes the charged excitations at an integer filling to disperse, forming new bands. If the excitation moves the filling away from the charge neutrality point, then it has a band minimum at the moire Brillouin zone center with a small mass that compares well with the experiment; if towards the charge neutrality point, then it has a much larger mass and a higher degeneracy. At a non-zero density away from an integer filling the excitations interact. The system on the small mass side has a large bandwidth and forms a Fermi liquid. On the large mass side the bandwidth is narrow, the compressibility is negative and the Fermi liquid is likely unstable. This explains the observed sawtooth features in compressibility, the Landau fans pointing away from charge neutrality as well as their degeneracies. By providing a description of the charge itineracy in the normal state this framework sets the stage for superconductivity at lower temperatures.

description: Document alignment techniques based on multilingual sentence representations have recently shown state of the art results. However, these techniques rely on unsupervised distance measurement techniques, which cannot be fined-tuned to the task at hand. In this paper, instead of these unsupervised distance measurement techniques, we employ Metric Learning to derive task-specific distance measurements. These measurements are supervised, meaning that the distance measurement metric is trained using a parallel dataset. Using a dataset belonging to English, Sinhala, and Tamil, which belong to three different language families, we show that these task-specific supervised distance learning metrics outperform their unsupervised counterparts, for document alignment.

description: Event sourced systems are increasing in popularity because they are reliable, flexible, and scalable. In this article, we point a microscope at a software architecture pattern that is rapidly gaining popularity in industry, but has not received as much attention from the scientific community. We do so through constructivist grounded theory, which proves a suitable qualitative method for extracting architectural knowledge from practitioners. Based on the discussion of 19 event sourced systems we explore the rationale for and the context of the event sourcing pattern. A description of the pattern itself and its relation to other patterns as discussed with practitioners is given. The description itself is grounded in the experience of 25 engineers, making it a reliable source for both new practitioners and scientists. We identify five challenges that practitioners experience: event system evolution, the steep learning curve, lack of available technology, rebuilding projections, and data privacy. For the first challenge of event system evolution, we uncover five tactics and solutions that support practitioners in their design choices when developing evolving event sourced systems: versioned events, weak schema, upcasting, in-place transformation, and copy-and-transform.

description: The aim of the work presented in this paper is to test and optimise supernova detection methods based on the optimal image subtraction technique. The main focus is on applying the detection methods to wide field supernova imaging surveys and in particular to the Stockholm VIMOS Supernova Survey (SVISS). We have constructed a supernova detection pipeline for imaging surveys. The core of the pipeline is image subtraction using the ISIS 2.2 package. Using real data from the SVISS we simulate supernovae in the images, both inside and outside galaxies. The detection pipeline is then run on the simulated frames and the effects of image quality and subtraction parameters on the detection efficiency and photometric accuracy are studied. The pipeline allows efficient detection of faint supernovae in the deep imaging data. It also allows controlling and correcting for possible systematic effects in the SN detection and photometry. We find such a systematic effect in the form of a small systematic flux offset remaining at the positions of galaxies in the subtracted frames. This offset will not only affect the photometric accuracy of the survey, but also the detection efficiencies. Our study has shown that ISIS 2.2 works well for the SVISS data. We have found that the detection efficiency and photometric accuracy of the survey are affected by the stamp selection for the image subtraction and by host galaxy brightness. With our tools the subtraction results can be further optimised, any systematic effects can be controlled and photometric errors estimated, which is very important for the SVISS, as well as for future SN searches based on large imaging surveys such as Pan-STARRS and LSST.

description: Transparent Conductive Oxides (TCOs) are a class of materials that combine high optical transparency with high electrical conductivity. This property makes them uniquely appealing as transparent-conductive electrodes in solar cells and interesting for optoelectronics and infrared-plasmonics applications. One of the new challenges that researchers and engineers are facing is merging optical and electrical control in a single device for developing next-generation photovoltaic, opto-electronic devices and energyefficient solid-state lighting. In this work, we investigated the possible variations in the dielectric properties of aluminum-doped ZnO (AZO) upon gating, by means of Spectroscopic Ellipsometry (SE). We investigated the electrical-bias-dependent optical response of thin AZO films fabricated by magnetron sputtering, within a parallel-plane capacitor configuration. We address the possibility to control their optical and electric performances by applying bias, monitoring the effect of charge injection/depletion in the AZO layer by means of in-operando SE vs applied gate voltage.

description: We investigate the effect of general time transformations on the phase synchronization (PS) phenomenon and the mutual information rate (MIR) between pairs of nodes in dynamical networks. We demonstrate two important results concerning the invariance of both PS and the MIR. Under time transformations PS can neither be introduced nor destroyed and the MIR cannot be raised from zero. On the other hand, for proper time transformations the timing between the cycles of the coupled oscillators can be largely improved. Finally, we discuss the relevance of our findings for communication in dynamical networks.

description: Forests include a great variety of communities of organisms interacting with their physical environment: multi-aged natural forests, even-aged commercial plantations and secondary forests invaded by foreign tree species. The challenge is to sustain their ability to function by adapting to changing climates and at the same time satisfying a multitude of human needs.The ongoing global changes pose several significant challenges to forest research and management, including deforestation and illegal logging, indigenous rights and land tenure, forest degradation and invasive species, as well as land-use conflicts and human-wild-life conflicts. Addressing these grand challenges requires a combination of policies, international cooperation, and transformative tools such as artificial intelligence (AI).

description: Mobile sensors provide a new opportunity to measure and intervene in child development. The present study seeks to determine the conditions for parental participation in mobile sensor studies and applications. A survey was administered to parents (n=210) of a child under the age of five. Results indicate that parents are significantly more willing to collect information on physical activity/vitals and location type (82 and 78% respectively indicated they were at least somewhat willing; ≥SW) compared to home presence and social media data (61 and 73% ≥SW). Parents are least willing to collect continuous audio and video data (49% and 54% ≥SW). They are slightly but significantly more willing to collect audio snippets or features (59 and 61% ≥SW). They are most willing to collect highly-sensitive data if it stays within their household (78% ≥SW), however, they are significantly more willing to share with researchers (71% ≥SW) than with tech companies (62% ≥SW). Parents are more willing to share their children's data if it could provide feedback on their parenting style or allergens (88 and 86% were at least somewhat more willing). Parents who have strong values of hedonism, benevolence, tradition, self-direction and power will be more willing and likely to participate in a mobile-sensing study than parents who have strong values of stimulation, achievement, conformity, security, and universalism. A recruitment message that is derived from the security value type will be most effective. These results advise designers and developers of mobile-sensing applications to be more mindful of the types of data that are most sensitive. The results also provide guidelines to researchers on how to effectively market their research and increase participation.
Relation between fundamental estimation limit and stability in linear quantum systems with imperfect measurement

description: From the noncommutative nature of quantum mechanics, estimation of canonical observables $\hat{q}$ and $\hat{p}$ is essentially restricted in its performance by the Heisenberg uncertainty relation, $\mean{Δ\hat{q}^2}\mean{Δ\hat{p}^2}\geq \hbar^2/4$. This fundamental lower-bound may become bigger when taking the structure and quality of a specific measurement apparatus into account. In this paper, we consider a particle subjected to a linear dynamics that is continuously monitored with efficiency $η\in(0,1]$. It is then clarified that the above Heisenberg uncertainty relation is replaced by $\mean{Δ\hat{q}^2}\mean{Δ\hat{p}^2}\geq \hbar^2/4η$ if the monitored system is unstable, while there exists a stable quantum system for which the Heisenberg limit is reached.

description: This article explores the uses of sources in coverage of the COVID-19 pandemic in social media posts of mainstream news organizations in Brazil, Chile, Germany, Mexico, Spain, the U.K., and the U.S. Based on computational content analysis, our study analyzes the sources and actors present in more than 940,000 posts on COVID-19 published in the 227 Facebook, Instagram, and Twitter accounts of 78 sampled news outlets between January 1 and December 31 of 2020, comparing their relative importance across countries, across media platforms, and across time as the pandemic evolved in each country. The analysis shows the dominance of political sources across countries and platforms, particularly in Latin America, demonstrating a strong role of the state in constructing pandemic news and suggesting that mainstream news organizations' social media posts maintain a strong elite orientation. Health sources were also prominent — consistent with the defining role of biomedical authority in health coverage—, while significant diversity of sources, including citizen sources, emerged as the pandemic went on. Our results also revealed that the use of specific sources significantly varied over time. These variations tend to go hand in hand with specific global milestones of the pandemic.
