description: We consider an emulsion whose droplets contain a trapped species (insoluble in the continuous phase), and study the emulsion's stability against coarsening via Lifshitz-Slyozov dynamics (Ostwald Ripening). Extending an earlier treatment by Kabalnov et al(Colloids and Surfaces, 24,(1987), 19-32), we derive a general condition on the mean initial droplet volume which ensures stability, even when arbitrary polydispersity is present in both size and composition of the initial droplets. We distinguish "nucleated" coarsening, which requires either fluctuations about the mean field equations or a tail in the initial droplet size distribution, from "spinodal" coarsening in which a typical droplet is locally unstable. A weaker condition for stability, previously suggested by Kabalnov et al., is sufficient only to prevent "spinodal" coarsening and is best viewed as a condition for metastability. The coarsening of unstable emulsions is considered, and shown at long times to resemble that of ordinary emulsions (with no trapped species), but with a reduced value of the initial volume fraction of dispersed phase. We discuss the physical principles relevant to the stability of emulsions with trapped species, describing how these may be exploited to restabilise partially coarsened emulsions and to "shrink" previously formed emulsion droplets to form "miniemulsions".

description: В данной статье рассматривается сущность и проблемы использования двух теорий этногенеза – Л.Н. Гумилева и В.П. Бранского. Делается вывод о том, что несмотря на то, что оба автора представили логически обоснованные концепции, подход Л.Н. Гумилева подвергся критике за отсутствие четких определений «пассионарности» и «этноса». Кроме того. предсказательная сила концепции Л.Н. Гумилева ограничена из-за недостаточной фактологической базы и методических слабостей. Напротив, прогнозы, основанные на синергетической теории Бранского, применимы к современной действительности и могут теоретически моделировать развитие современных этносов. Немаловажным является предположение о том, что теория Л.Н. Гумилева может быть использована для субъективной интерпретации пассионарности различных народов, что может привести к вредному мифотворчеству и искажению истории.

description: One essential aspect of the Inter-Agency Space Debris Coordination Committee (IADC) space debris mitigation guidelines is the clearance from the protected regions at the end of the mission. More specifically, for the Low Earth Orbit (LEO) region, the orbital lifetime shall not exceed 25 years after the end of mission. Furthermore, the Federal Communications Commission (FCC) has lowered this limit to 5 years for all spacecraft under their jurisdiction, and the European Space Agency has already announced plans to follow a similar path with their Zero Debris policy. In this context, accurate orbital lifetime estimations become even more essential to assess the compliance of new missions to be launched, as well as to adequately assess the current state of the environment. The decay of objects in LEO is mainly dominated by drag, caused by the residual atmosphere in these lower altitudes. Consequently, the modelling of the ballistic coefficient has a great impact on the predicted orbital lifetime. RACER (Radiation and Atmospheric Drag Coefficient Estimation Routine) is a tool by the European Space Agency that estimates the ballistic coefficient of an object based on a set of Two-Line Elements (TLEs). This ballistic coefficient can be used to improve current orbital lifetime predictions. In this paper, the results obtained from the estimation of the ballistic coefficient using RACER are analyzed, aiming to understand the different parameters that affect its evolution and to identify patterns corresponding to similar objects. Additionally, different methodologies are investigated, which make use of these results to improve the orbital lifetime estimations for a set of rocket stages.

description: Open-cell graphitic foams were fabricated by chemical vapor deposition using nickel templates and their compressive responses were measured over a range of relative densities. The mechanical response required an interpretation in terms of a hierarchical micromechanical model, spanning 3 distinct length scales. The power law scaling of elastic modulus and yield strength versus relative density suggests that the cell walls of the graphitic foam deform by bending. The length scale of the unit cell of the foam is set by the length of the struts comprising the cell wall, and is termed level I. The cell walls comprise hollow triangular tubes, and bending of these strut-like tubes involves axial stretching of the tube walls. This length scale is termed level II. In turn, the tube walls form a wavy stack of graphitic layers, and this waviness induces interlayer shear of the graphitic layers when the tube walls are subjected to axial stretch. The thickness of the tube wall defines the third length scale, termed level III. We show that the addition of a thin, flexible ceramic Al2O3 scaffold stiffens and strengthens the foam, yet preserves the power law scaling. The hierarchical model gives fresh insight into the mechanical properties of foams with cell walls made from emergent 2D layered solids.

description: One of the essential aspects of space debris mitigation is the performance of Post-Mission Disposal (PMD) once the mission of a space vehicle has concluded. The main goal of the PMD is to avoid the creation of further space debris, especially mitigating the risk for on-orbit collisions or explosions that would cause a fragmentation and potentially contribute to the collisional cascading effect known as the Kessler syndrome. This paper focuses on the rocket bodies launched since 2016 that were not compliant with the 25 years rule established by the IADC space debris mitigation guidelines. The cumulative collision probability of these rocket bodies since their launch until their re-entry was studied as a measure of the risk that they pose to the environment. Moreover, the most suitable disposal orbits for these objects in order to be compliant were studied, as well as the ∆v requirements to reach that orbit and the risk mitigation resulting from these manoeuvres. Furthermore, a specific stage was chosen for a more detailed study of its disposal. The reduction of risk achievable by different values of the ∆v used in the disposal was analysed. Additionally, the impact of the attitude of the stage by means of its cross-section was studied, showing how variations in this value can lead to very different values of the remaining lifetime as well as the cumulative collision probability. The results show an in-depth analysis of the disposal options of rocket stages, raising awareness of the large impact that this measure has on the collision probability of these objects while they are on orbit and therefore on their impact on the future evolution of the space debris environment.

description: Many natural and social systems develop complex networks, that are usually modelled as random graphs. The eigenvalue spectrum of these graphs provides information about their structural properties. While the semi-circle law is known to describe the spectral density of uncorrelated random graphs, much less is known about the eigenvalues of real-world graphs, describing such complex systems as the Internet, metabolic pathways, networks of power stations, scientific collaborations or movie actors, which are inherently correlated and usually very sparse. An important limitation in addressing the spectra of these systems is that the numerical determination of the spectra for systems with more than a few thousand nodes is prohibitively time and memory consuming. Making use of recent advances in algorithms for spectral characterization, here we develop new methods to determine the eigenvalues of networks comparable in size to real systems, obtaining several surprising results on the spectra of adjacency matrices corresponding to models of real-world graphs. We find that when the number of links grows as the number of nodes, the spectral density of uncorrelated random graphs does not converge to the semi-circle law. Furthermore, the spectral densities of real-world graphs have specific features depending on the details of the corresponding models. In particular, scale-free graphs develop a triangle-like spectral density with a power law tail, while small-world graphs have a complex spectral density function consisting of several sharp peaks. These and further results indicate that the spectra of correlated graphs represent a practical tool for graph classification and can provide useful insight into the relevant structural properties of real networks.

Раскрывается содержание и значение специфических умений и навыков коммуникации участников судебного разбирательства, их влияние на применение правовых знаний. Сделан вывод о том, что требования к наличию юридико-коммуникативной компетентности могут быть предъявлены только к профессиональным участникам судебного производства в лице судей, иных участников судебного процесса, а также представителей сторон, имеющих высшее юридическое образование. Отсутствие отдельных коммуникативных умений и навыков не позволяет достичь задач судопроизводства, а как следствие, эффективного разрешения правовых споров и конфликтов в суде, что может негативно сказаться на качестве отправления правосудия и привести к упадку судебной системы в России.

description: Marine hydrokinetic (MHK) power generation systems enable harvesting energy from waterways without the need for water impoundment. A major research challenge for numerical simulations of field-scale MHK farms stems from the large disparity in scales between the size of waterway and the energy harvesting device. We propose a large-eddy simulation (LES) framework to perform high-fidelity, multi-resolution simulations of MHK arrays in a real-life marine environment using a novel unstructured Cartesian flow solver coupled with a sharp-interface immersed boundary method. The potential of the method as a powerful engineering design tool is demonstrated by applying it to simulate a 30 turbine MHK array under development in the East River in New York City. A virtual model of the MHK power-plant is reconstructed from high-resolution bathymetry measurements in the East River and the 30 turbines placed in 10 TriFrame arrangements as designed by Verdant Power. A locally refined, near the individual turbines, background unstructured Cartesian grid enables LES across a range of geometric scales of relevance spanning approximately five orders of magnitude. The simulated flow-field is compared with a baseline LES of the flow in the East River without turbines. While velocity deficits and increased levels of turbulence kinetic energy are observed in the vicinity of the turbine wakes, away from the turbines as well as on the water surface only small increase in mean momentum is found. Therefore, our results point to the conclusion that MHK energy harvesting from large rivers is possible without a significant disruption of the river flow.

description: In the implementation and use of research information systems (RIS) in scientific institutions, text data mining and semantic technologies are a key technology for the meaningful use of large amounts of data. It is not the collection of data that is difficult, but the further processing and integration of the data in RIS. Data is usually not uniformly formatted and structured, such as texts and tables that cannot be linked. These include various source systems with their different data formats such as project and publication databases, CERIF and RCD data model, etc. Internal and external data sources continue to develop. On the one hand, they must be constantly synchronized and the results of the data links checked. On the other hand, the texts must be processed in natural language and certain information extracted. Using text data mining, the quality of the metadata is analyzed and this identifies the entities and general keywords. So that the user is supported in the search for interesting research information. The information age makes it easier to store huge amounts of data and increase the number of documents on the internet, in institutions' intranets, in newswires and blogs is overwhelming. Search engines should help to specifically open up these sources of information and make them usable for administrative and research purposes. Against this backdrop, the aim of this paper is to provide an overview of text data mining techniques and the management of successful data quality for RIS in the context of open data and open science in scientific institutions and libraries, as well as to provide ideas for their application. In particular, solutions for the RIS will be presented.

description: We write exact renormalization-group recursion relations for a ferromagnetic Ising model on the diamond hierarchical lattice with an aperiodic distribution of exchange interactions according to a class of generalized two-letter Fibonacci sequences. For small geometric fluctuations, the critical behavior is unchanged with respect to the uniform case. For large fluctuations, the uniform fixed point in the parameter space becomes fully unstable. We analyze some limiting cases, and propose a heuristic criterion to check the relevance of the fluctuations.

description: A preliminary version of this article appeared in the proceedings of the conference LICS 2020
description: We provide a tight characterisation of proof size in resolution for quantified Boolean formulas (QBF) via circuit complexity. Such a characterisation was previously obtained for a hierarchy of QBF Frege systems [16], but leaving open the most important case of QBF resolution. Different from the Frege case, our characterisation uses a new version of decision lists as its circuit model, which is stronger than the CNFs the system works with. Our decision list model is well suited to compute countermodels for QBFs. Our characterisation works for both Q-Resolution and QU-Resolution. Using our characterisation, we obtain a size-width relation for QBF resolution in the spirit of the celebrated result for propositional resolution [4]. However, our result is not just a replication of the propositional relation—intriguingly ruled out for QBF in previous research [12]—but shows a different dependence between size, width, and quantifier complexity. An essential ingredient is an improved relation between the size and width of term decision lists; this may be of independent interest. We demonstrate that our new technique elegantly reproves known QBF hardness results and unifies previous lower-bound techniques in the QBF domain.

description: The aim of the present thesis was to document theoretically the visual work entitled “Specimen Workshop” that deals with the social phenomenon of precariousness and to present the artistic research that led to it. The artistic research includes various artistic practices. Through the various ways of creating the artworks (the educational program at the Second Chance School of the prison in Diavata, the participative installation, the explorations for finding urban imprints of precariousness and collecting material for processing), the research aims to analyze the phenomenon from different perspectives, critically addressing the inherent ambiguity of its positivisation. At the same time, theoretical research studies the history of the phenomenon in the last 200 years and how precariousness is reflected in the city. Furthermore, the research juxtaposes the above findings with certain aspects of the theory of precarity which is related to contemporary art and forms the ambiguity of the precarious condition such as the theory of autonomous Marxists and the theory of Nicolas Bourriaud.

description: We present a homogeneous catalog of 275 large (effective radius $\gtrsim$ 5.3 arcsec) ultra-diffuse galaxy (UDG) candidates lying within an $\approx$ 290 square degree region surrounding the Coma cluster. The catalog results from our automated postprocessing of data from the Legacy Surveys, a three-band imaging survey covering 14,000 square degrees of the extragalactic sky. We describe a pipeline that identifies UDGs and provides their basic parameters. The survey is as complete in these large UDGs as previously published UDG surveys of the central region of the Coma cluster. We conclude that the majority of our detections are at roughly the distance of the Coma cluster, implying effective radii $\ge 2.5$ kpc, and that our sample contains a significant number of analogs of DF 44, where the effective radius exceeds 4 kpc, both within the cluster and in the surrounding field. The $g-z$ color of our UDGs spans a large range, suggesting that even large UDGs may reflect a range of formation histories. A majority of the UDGs are consistent with being lower stellar mass analogs of red sequence galaxies, but we find both red and blue UDG candidates in the vicinity of the Coma cluster and a relative overabundance of blue UDG candidates in the lower density environments and the field. Our eventual processing of the full Legacy Surveys data will produce the largest, most homogeneous sample of large UDGs.

description: Distributed Key Generation (DKG) is an extensively researched topic as it is fundamental to threshold cryptosystems. Emerging technologies such as blockchains benefit massively from applying threshold cryptography in consensus protocols, randomness beacons, and threshold signatures. However, blockchains and smart contracts also enable further improvements of DKG protocols by providing a decentralized computation and communication platform. For that reason, we propose a DKG protocol that uses smart contracts to ensure the correct execution of the protocol, allow dynamic participation, and provide crypto-economic incentives to encourage honest behavior. The DKG protocol uses a dispute and key derivation mechanism based on Zero-Knowledge Succinct Non-interactive Arguments of Knowledge (zk-SNARKs) to reduce the costs of applying smart contracts by moving the computations off-chain, where the smart contract only verifies the correctness of the computation.

description: In the domain of graph neural networks (GNNs), pooling operators are fundamental to reduce the size of the graph by simplifying graph structures and vertex features. Recent advances have shown that well-designed pooling operators, coupled with message-passing layers, can endow hierarchical GNNs with an expressive power regarding the graph isomorphism test that is equal to the Weisfeiler-Leman test. However, the ability of hierarchical GNNs to increase expressive power by utilizing graph coarsening was not yet explored. This results in uncertainties about the benefits of pooling operators and a lack of sufficient properties to guide their design. In this work, we identify conditions for pooling operators to generate WL-distinguishable coarsened graphs from originally WL-indistinguishable but non-isomorphic graphs. Our conditions are versatile and can be tailored to specific tasks and data characteristics, offering a promising avenue for further research.

description: Consider the standard stochastic reaction network model where the dynamics is given by a continuous-time Markov chain over a discrete lattice. For such models, estimation of parameter sensitivities is an important problem, but the existing computational approaches to solve this problem usually require time-consuming Monte Carlo simulations of the reaction dynamics. Therefore these simulation-based approaches can only be expected to work over finite time-intervals, while it is often of interest in applications to examine the sensitivity values at the steady-state after the Markov chain has relaxed to its stationary distribution. The aim of this paper is to present a computational method for the estimation of steady-state parameter sensitivities, which instead of using simulations, relies on the recently developed stationary Finite State Projection (sFSP) algorithm [J. Chem. Phys. 147, 154101 (2017)] that provides an accurate estimate of the stationary distribution at a fixed set of parameters. We show that sensitivity values at these parameters can be estimated from the solution of a Poisson equation associated with the infinitesimal generator of the Markov chain. We develop an approach to numerically solve the Poisson equation and this yields an efficient estimator for steady-state parameter sensitivities. We illustrate this method using several examples.

Periodic Modulation Induced Increase of Reaction Rates in Autocatalytic Systems

description: We propose a new mechanism to increase the reactions ratesin multistable autocatalytic systems. The mechanism is based upon the possibility for the enhancement of the response of the system due to the cooperative behavior between the noise and an external periodic modulation. In order to illustrate this feature we compute the reaction velocities for the particular case of the Sel'Kov model, showing that they increase significantly when the periodic modulation is introduced. This behavior originates from the existence of a minimum in the mean first passage time, one of the signatures of stochastic resonance.

description: Linear settlements are present in many rural regions in Europe: from England in the North to Italy in the South, from France in the West to Ukraine in the East. Although the villages vary widely in form and age, as well as in circumstances of their development - from historically grown to planned settlements - the distribution of linear settlements in their general area of distribution area suggests that there are specific conditions that favour their occurrence. While there are linear settlements alongside canals or streams, as well as villages arranged along features such as village greens (Dorfanger), the most basic form of linear settlement is the street village (Straßendorf). It has a uniform urban parterre structure that serves all essential settlement tasks, such as dwelling, working, supply, recreation, worship, and traffic. To date, there is a lack of comprehensive research regarding the preconditions for the development and spread of those linear settlements. Through a morphological analysis of relevant urban design factors our research will fill this knowledge gap. To start with, this paper offers first results and insights into analyses of linear settlements in areas of Austria, Slovakia and Hungary. The study is embedded in a recently initiated larger research project concerning the transformative potentials of linear settlement structures in the European area. Besides results, that are to be understood as first approximations, a short historical overview on the most important milestones of local settlement development in the study area is given. Furthermore, morphological analysis of relevant factors, local typologies and patterns of buildings and settlement structures as well as specific spatial qualities of villages are addressed with regard to the genesis of the investigated linear settlements.
Low-energy sector quantization of a massless scalar field outside a Reissner-Nordstrom black hole and static sources

description: We quantize the low-energy sector of a massless scalar field in the Reissner-Nordstrom spacetime. This allows the analysis of processes involving soft scalar particles occurring outside charged black holes. In particular, we compute the response of a static scalar source interacting with Hawking radiation using the Unruh (and the Hartle-Hawking) vacuum. This response is compared with the one obtained when the source is uniformly accelerated in the usual vacuum of the Minkowski spacetime with the same proper acceleration. We show that both responses are in general different in opposition to the result obtained when the Reissner-Nordstrom black hole is replaced by a Schwarzschild one. The conceptual relevance of this result is commented.

description: We consider the $AdS_5$ solution deformed by a non-constant dilaton interpolating between the standard AdS (UV region) and flat boundary background (IR region). We show that this dilatonic solution can be generalized to the case of a non-flat boundaries provided that the metric of the boundaries satisfies the vacuum Einstein field equations. As an example, we describe the case when the four-dimensional boundaries represent the Kerr space-time.

description: Num verso da “Saudação a Walt Whitman”, Álvaro de Campos define o desejo de fazer arte como o equivalente adulto do impulso infantil que leva uma criança a entreter-se com brinquedos. Este género de definição de autor ocorre com alguma frequência na obra de Pessoa. Numa carta de Fevereiro de 1915 a Ronald de Carvalho, por exemplo, Pessoa sugere que a actividade poética a que tanto ele como o destinatário se consagram não é senão a resposta dos adultos que são ao facto de, a dada altura, lhes terem sido tirados os brinquedos com que se entretinham. A análise detalhada de Antinous que proponho neste ensaio procurará defender que o longo epicédio em inglês publicado em 1918 é uma versão poética desta tese peculiar acerca de autoria, e que a actividade de estatuário a que o imperador Adriano promete dedicar-se depois da morte de Antínoo corresponde, acima de tudo, a um modo adulto de lidar com a inevitabilidade da perda do brinquedo com que se entretinha enquanto jovem.

description: We investigate the phase diagram of a mixed spin-1/2--spin-1 Ising system in the presence of quenched disordered anisotropy. We carry out a mean-field and a standard self-consistent Bethe--Peierls calculation. Depending on the amount of disorder, there appear novel transition lines and multicritical points. Also, we report some connections with a percolation problem and an exact result in one dimension.

description: This work studies the hydrodynamics of self-gravitating compressible isothermal fluids. We show that the hydrodynamic evolution equations in absence of viscosity are scale covariant. We study the evolution of the time dependent fluctuations around singular and regular isothermal spheres. We linearize the fluid equations around such stationary solutions and apply Laplace transform to solve them. We find that the system is stable below a critical size (X ~ 9.0 in dimensionless variables) and unstable above; this size is the same critical size found in the study of the thermodynamical stability in the canonical ensemble and associated to a center-to-border density ratio of 32.1 . We prove that the value of this critical size is independent of the Reynolds number of the system. Furthermore, we give a detailed description of the series of successive dynamical instabilities that appear at higher and higher sizes following the geometric progression X_n ~ 10.7^n. We turn then to study exact solutions of the hydrodynamic equations without viscosity and we provide analytic and numerical axisymmetric soliton-type solutions. The stability of exact solutions corresponding to a collapsing filament is studied by computing linear fluctuations. Radial fluctuations growing faster than the background are found for all sizes of the system. However, a critical size (X ~ 4.5) appears, separating a weakly from a strongly unstable regime.

description: The paper deals with the genesis of the Viennese Straßendorf (street village, a special form of linear settlement). In general, it can be stated that the Straßendorf does indeed represent the archetype of an enclosed street space and can thus be described as the nucleus of urbanity and arguably also as one original form of a settlement of short distances. The following text refers to street villages that are located in moderate terrain, as opposed to longitudinal settlements that develop on slope ridges or narrow mountain valleys. In any case its linear growth is limited: when a certain length is reached, and further longitudinal expansion is no longer convenient, parallel or orthogonal streets are introduced to the system. Many street villages in formerly rural areas are now what can be considered the main street of an otherwise often scattered settlement. In other cases, such as in Vienna, expanding cities have incorporated the former villages into their metropolitan street network, where they now typically serve as an urban sub-centre, or represent an arterial road and a development axis for the city. Regarding the city of Vienna, more than 150 medieval and early modern villages have been identified in today's municipal area, many of which are still recognisable in the townscape. To date, those patterns¾their historical development and their current urban and functional structure¾have not been studied systematically. This is what our paper aims for: A comprehensive research of historic literature and maps will allow a detailed description and localization of this special form of linear settlements in and around Vienna. The comparison of the form and functions of historical street villages with their contemporary counterparts serves as a basis for understanding the inner configuration of a Straßendorf and their overarching macro-structural incorporation into the urban body.
