description: The spherical-to-prolate shape transition in neutron-rich Cr isotopes from N = 34 to 42 is studied by solving the collective Schr\"odinger equation for the five-dimensional quadrupole collective Hamiltonian. The collective potential and inertial functions are microscopically derived with use of the constrained Hartree-Fock-Bogoliubov plus local quasiparticle random-phase approximation method. Nature of the quadrupole collectivity of low-lying states is discussed by evaluating excitation spectra and electric quadrupole moments and transition strengths. The result of calculation indicates that Cr isotopes around 64Cr are prolately deformed but still possess transitional character; large-amplitude shape fluctuations dominate in their low-lying states.

description: Im aktuellen bildungspolitischen und schulpädagogischen Diskurs werden im Zusammenhang mit Digitalisierungsmassnahmen in Schulen Kompetenzanforderungen deutlich, die die heterogene Lerner:innenschaft dazu befähigen sollen, «sich in einer digitalisierten Gesellschaft zurechtzufinden» (Autorengruppe Bildungsberichterstattung 2020). Unberücksichtigt bleiben die Erfahrungen von Kindern und Jugendlichen in digitalen Jugendkulturen, in deren Rahmen sie mit ihrem Wunsch nach Anerkennung und Zugehörigkeit ohne Anleitung quasi «nebenbei» grundlegende personale, soziale und anwendungsbezogene fachliche Kompetenzen erwerben. Der Beitrag fragt aus einer diversitätssensiblen wissenschaftlich-analytischen Perspektive unter Bezugnahme auf die Konstruktion von Zugehörigkeit (Hall 2004; Mecheril 2003) und Habitus (Bourdieu 1992; Kramer 2014) nach den lebensweltlichen Bedürfnissen und Erfahrungen von Schüler:innen, stellt diese gegenwärtig sichtbaren institutionell-digitalen Kompetenzanforderungen in Schulen gegenüber und arbeitet auf der Grundlage der Annahme eines konstruierten «digital divides» Problematiken und Gefahren der Differenzierung und Verfestigung von Chancenungleichheit heraus. Die Ergebnisse verweisen in pädagogisch-didaktischer Hinsicht auf die Notwendigkeit der Etablierung einer digitalen Lernkultur, die die Herausbildung einer Kompetenz zum Ziel hat, in deren Rahmen die selbstbestimmte und gleichermassen sozial verantwortungsvolle Herstellung lebensweltlich-digitaler Zugehörigkeiten durch Schüler:innen unabhängig von ihrer «Ethnie», ihres «Geschlechts», ihrer «Bildungsposition» etc. möglich wird.
Applying communication theory to public archaeology

description: Bibliography: p. 118-133
description: With easily accessible mass communication technologies and advanced presentation software, archaeology is increasingly relying on more complex communication processes to engage the public. With little academic recognition, however, communication studies in archaeology have largely been limited to commentary and speculation. In this thesis, variables that affect the mass communication process of a web-based archaeological message were tested to ascertain what areas of communication theory archaeologists should be examining (Arctic archaeology was used as an example). It was found that when grade six elementary school students accessed and wrote about what they had learned from a website pertaining to archaeology, multiple factors including content, medium, communication dynamics, and technology affected choice and information retention. This thesis demonstrates that for archaeologists to effectively deliver and maintain control over the perception of their discipline, they need to understand the processes by which they communicate.

description: Purpose: Outcomes of multiple myeloma (MM) patients who are refractory to daratumumab are dismal and no standard of treatment exists for this patients’ population. Here, we investigate the role of pomalidomide combinations in daratumumabrefractory MM patients. Methods: We performed a retrospective analysis of myeloma patients treated at four referral centers (three in Germany and one in Italy). Review chart identified 30 patients with relapsed and refractory myeloma, who progressed during treatment with daratumumab and were treated with pomalidomide-based combinations in the subsequent lines of therapy. Results: Responses improved from 37% with daratumumab to 53% with pomalidomide. Of seven patients with extramedullary MM (EMM), four achieved a clinical stabilization with pomalidomide, including one patient with a long-lasting complete response. Median progression-free survival and overall survival were 6 and 12 months, respectively. Pomalidomide combinations were well tolerated, no patient discontinued treatment due to adverse events. Conclusion: These data show that pomalidomide-based combinations

description: The errors that Java programmers are likely to encounter can roughly be categorized into three groups: compile-time (semantic and syntactic), logical, and runtime (exceptions). While much work has focused on the first two, there are very few tools that exist for interpreting the sometimes cryptic messages that result from runtime errors. Novice programmers in particular have difficulty dealing with uncaught exceptions in their code and the resulting stack traces, which are by no means easy to understand. We present Backstop, a tool for debugging runtime errors in Java applications. This tool provides more user-friendly error messages when an uncaught exception occurs, but also provides debugging support by allowing users to watch the execution of the program and the changes to the values of variables. We also present the results of two studies conducted on introductory-level programmers using the two different features of the tool.

description: Motivated by 3.9 sigma evidence of a CP-violating phase beyond the standard model in the like-sign dimuon asymmetry reported by DO, we examine the potential for two Higgs doublet models (2HDMs) to achieve successful electroweak baryogenesis (EWBG) while explaining the dimuon anomaly. Our emphasis is on the minimal flavour violating 2HDM, but our numerical scans of model parameter space include type I and type II models as special cases. We incorporate relevant particle physics constraints, including electroweak precision data, b to s gamma, the neutron electric dipole moment, R_b, and perturbative coupling bounds to constrain the model. Surprisingly, we find that a large enough baryon asymmetry is only consistently achieved in a small subset of parameter space in 2HDMs, regardless of trying to simultaneously account for any B physics anomaly. There is some tension between simultaneous explanation of the dimuon anomaly and baryogenesis, but using a Markov chain Monte Carlo we find several models within 1 sigma of the central values. We point out shortcomings with previous studies that reached different conclusions. The restricted parameter space that allows for EWBG makes this scenario highly predictive for collider searches. We discuss the most promising signatures to pursue at the LHC for EWBG-compatible models.

description: Since 2000, China's outward foreign direct investment (OFDI) has grown at an accelerating rate as a result of a switch in government policy to strong encouragement of Chinese enterprises to "go global." The bulk of this investment has been into the primary and tertiary sectors, with relatively little so far going into manufacturing. Most has gone to Asia, but Chinese investment is now spreading throughout the world. The precise geographical distribution is veiled, as much of it passes through tax havens. The Government has been slow to tackle administrative obstacles to Chinese companies wishing to invest abroad, but has recently begun to relax them. The global crisis has presented opportunities for Chinese multinationals, which were less seriously affected than their counterparts in the developed world, to raise their stake in the world economy.

description: Integrative taxonomy is a fundamental part of biodiversity and combines traditional morphology with additional methods such as DNA sequencing or biochemistry. Here, we aim to establish untargeted metabolomics for use in chemotaxonomy. We used three thallose liverwort species Riccia glauca, R. sorocarpa, and R. warnstorfii (order Marchantiales, Ricciaceae) with Lunularia cruciata (order Marchantiales, Lunulariacea) as an outgroup. Liquid chromatography highresolution mass-spectrometry (UPLC/ESI-QTOF-MS) with data-dependent acquisition (DDA-MS) were integrated with DNA marker-based sequencing of the trnL-trnF region and high-resolution bioimaging. Our untargeted chemotaxonomy methodology enables us to distinguish taxa based on chemophenetic markers at different levels of complexity: (1) molecules, (2) compound classes, (3) compound superclasses, and (4) molecular descriptors. For the investigated Riccia species, we identified 71 chemophenetic markers at the molecular level, a characteristic composition in 21 compound classes, and 21 molecular descriptors largely indicating electron state, presence of chemical motifs, and hydrogen bonds. Our untargeted approach revealed many chemophenetic markers at different complexity levels that can provide more mechanistic insight into phylogenetic delimitation of species within a clade than genetic-based methods coupled with traditional morphology-based information. However, analytical and bioinformatics analysis methods still need to be better integrated to link the chemophenetic information at multiple scales.
Revisiting irrigation management transfer : a case study of a Philippine municipality’s experience in transferring irrigation management to farmer associations
Creators: name: Bedore, Jennifer Lauren

description: There is a lack of data and analysis relating to implementation processes and impacts for Irrigation Management Transfer (IMT), particularly at the community level. This is despite the fact that IMT has become one of the most popular trends in irrigation management worldwide. This research fills key gaps in knowledge about IMT in practice, specifically with respect to: (1) the different approaches being used, the constraints to implementation, the impacts on all stakeholders; and (2) the suitability of IMT in different social, political and economic settings, through a case study analysis of the municipality of Plaridel, Bulacan, Philippines. Based on a review of literature focused on the works of the leading experts in IMT, seven 'best practices', with respect to the implementation of IMT, are formulated. Through semi-structured interviews and data collection, the implementation of IMT in Plaridel is then evaluated against these seven 'best practices'. It is found that all seven of the 'best practices' are not currently operational in the municipality and that as a result, there is an extremely high likelihood that Plaridel's farms and Irrigation Associations (IAs) will not be viable in the near future. The main reasons for this being the absence of clearly recognized and sustainable water rights and service and insufficient financial resources provided by the implementing irrigation agency, the National Irrigation Administration (NIA). This study argues that this scenario is likely because NIA is implementing IMT solely to reduce its own financial costs in operating and maintaining Plaridel's irrigation systems and not to improve productivity or the livelihoods of Plaridel's farmers. Plaridel is a cautionary tale to any government that is planning to implement IMT, as it shows how IMT is no quick fix to a financially unviable Irrigation Agency or agricultural sector. Rather it is a difficult, painstaking process that requires substantial financing and commitment.

description: The differential cross sections for the neutrino-induced weak charged current production of strange particles in the threshold energy region are presented. The general representation of the weak hadronic current is newly developed in terms of eighteen unknown invariant amplitudes to parametrize the hadron vertex. The Born term approximation is used for the numerical calculations in the framework of the Cabibbo theory and SU(3) symmetry. For unpolarized octet baryons four processes are investigated, whereas in the case of polarized baryons only one process is chosen to study the sensitivity of the differential cross section to the various polarizations of the initial state nucleon and the final state hyperon.

description: As a small open economy, Belgium has been actively and successfully attracting inward foreign direct investment since the 1960s and consequently has one of the most internationalized economies in the world. Foreign affiliates represent approximately 35% and 21% of manufacturing and services jobs as well as 42% and 24% of value added by the manufacturing and services sector, respectively. Despite an overall drop in competitiveness of Belgian industry, the introduction of a new and innovative incentive, the notional interest deduction scheme, to lower corporate income tax for all firms in 2005 has led to an increase of inflows of equity capital from 2006 onward, although the financial crisis took its toll on inflows in 2008 and 2009. In addition, the risk capital allowance has done much to promote Belgium's role as a financial conduit, allowing a large proportion of the authorized capital to flow back to other countries in the form of loans. This trend was reinforced by the global financial crisis.
CONFU: Configuration Fuzzing Testing Framework for Software Vulnerability Detection

description: Many software security vulnerabilities only reveal themselves under certain conditions, i.e., particular configurations and inputs together with a certain runtime environment. One approach to detecting these vulnerabilities is fuzz testing. However, typical fuzz testing makes no guarantees regarding the syntactic and semantic validity of the input, or of how much of the input space will be explored. To address these problems, we present a new testing methodology called Configuration Fuzzing. Configuration Fuzzing is a technique whereby the configuration of the running application is mutated at certain execution points, in order to check for vulnerabilities that only arise in certain conditions. As the application runs in the deployment environment, this testing technique continuously fuzzes the configuration and checks "security invariants'' that, if violated, indicate a vulnerability. We discuss the approach and introduce a prototype framework called ConFu (CONfiguration FUzzing testing framework) for implementation. We also present the results of case studies that demonstrate the approach's feasibility and evaluate its performance.

description: Insect-provided pollination services are increasingly threatened due to alarming declines in insect pollinator populations. One of the main threats to insect pollinators and consequently pollination is urbanisation. Here, we investigate the effects of local habitat quality (patch size, flowering plant richness, bare soil cover, vegetation structure), degree of urbanisation (impervious surfaces) and 3D connectivity on bee, hoverfly and butterfly flower visitors and plant-flower visitor networks in flowerrich urban dry grasslands. Overall, the degree of urbanisation and the quality of the local habitat influenced the flowering plant and pollinator communities. Although flowering plant abundance increased with urbanisation, bee species richness and butterfly species richness decreased with increasing impervious surfaces. Flowering plant richness and ground nesting resource availability were positively related to bee richness and local vegetation structure boosted hoverfly and butterfly visitation rates. In terms of plant–pollinator interactions, insect pollinators visited a lower proportion of the available flowering plants in more urbanised areas and network modularity and specialisation increased with patch size. Our findings show that urban dry grasslands are valuable habitats for species-rich pollinator communities and further highlight the importance of minimizing the intensity of urbanisation and the potential of local management practices to support insect biodiversity in cities.

description: Using copulas to model the stochastic dependence of values, this paper establishes new general conditions on the profitability of product bundling. A multiproduct monopolist generally achieves higher profit from mixed bundling than from separate selling if consumer values for two products are negatively dependent, independent, or have limited positive dependence. With more than two goods, the same conditions are sufficient for an optimal monopoly selling scheme to include a bundle of at least two products. The profitability of monopoly bundling also extends to situations where a multiproduct firm competes with a single-product rival.
Hitch-hiking in the Canadian north: Clair W. Dawson's 1916 journal and correspondence

description: Bibliography: p. 126-130
description: This thesis prepares a transcription of the 1916 letters and journal of Clair W. Dawson, an American fur merchant in the Canadian north from 1912 until 1922. Over the course of his journey, he traveled over 22,000 kilometres and purchased $25,000 worth of fur while interacting with notable historical figures of the period and many indigenous peoples of the area. Not only is the journey interesting, his ability to tell the story conforms to contemporary ideas of North. Established ideas of North are compared to Dawson's narrative, where we find striking similarities, including a picaresque hero, and an ability to sustain an oral narrative. This thesis claims that the similarities stem from the same source: the landscape. The landscape's influence asserts itself into Dawson's writing through his use of oral storytelling. He unconsciously asserts the authority and presence of an animate landscape.

This paper describes HARP observations of the J = 3-2 transitions of 13CO and C18O towards Orion A. The 1500-resolution observations cover 5 pc of the Orion filament, including OMC1 (inc. BN-KL and Orion Bar), OMC 2/3 and OMC 4, and allow a comparative study of the molecular gas properties throughout the star-forming cloud. The filament shows a velocity gradient of ~1 km/s /pc between OMC 1, 2 and 3, and high velocity emission is detected in both isotopologues. The Orion Nebula and Bar have the largest masses and line widths, and dominate the mass and energetics of the high velocity material. Compact, spatially resolved emission from CH3CN, 13CH3OH, SO, HCOOCH3, C2H5OH, CH3CHO and CH3OCHO is detected towards the Orion Hot Core. The cloud is warm, with a median excitation temperature of ~24 K; the Orion Bar has the highest excitation temperature gas, at >80 K. The C18O excitation temperature correlates well with the dust temperature (to within 40%). The C18O emission is optically thin, and the 13CO emission is marginally optically thick; despite its high mass, OMC 1 shows the lowest opacities. A virial analysis indicates that Orion A is too massive for thermal or turbulent support, but is consistent with a model of a filamentary cloud that is threaded by helical magnetic fields. The variation of physical conditions across the cloud is reflected in the physical characteristics of the dust cores....continued

description: After opening its doors to foreign trade and investment in 1978, China has become the largest recipient of inward foreign direct investment (IFDI) among developing and transition economies. The early policy of investment attraction by means of fiscal incentives and special economic zones has been relaxed now that many -- though still not all -- operating environment deficiencies have been effectively addressed and strong domestic enterprises have developed. While China remains the developing world's favorite investment destination, the government is adopting a more selective approach that may result in slower IFDI growth. Although the global crisis reduced FDI inflows to China, this impact was lower than in many other FDI destinations, and flows have recovered considerably.

The study enrolled 120 pregnant women who were the 24th and 28th weeks of gestation, including GDM group (n = 58), the control group (n = 62). The NLR, PLR and MPV levels were measured. NLR, PLR and MPV were significantly higher in GDM compared with control group. Logistic regression analysis showed that elevated WBC, NLR, PLR and MPV was an independent variable for predicting GDM in pregnancy. The OR and 95% CI was (OR: 1.6, 95% CI: 1.2–2.5), (OR: 4.1, 95% CI: 1.3–13.1), (OR: 5.5, 95% CI: 1.5–20.0), (OR: 4.0, 95% CI: 1.2–12.0), respectively. Increased WBC, PLR, NLR, MPV were independent predictors of GDM.

description:
In 2014, the Joint United Nations Programme on HIV/AIDS (UNAIDS) announced the 90–90–90 targets to diagnose 90% of all HIV-positive persons, to provide antiretroviral therapy (ART) to 90% of those diagnosed, and to achieve viral suppression for 90% of those on ART by 2020. Significant progress has been made toward achieving this target. In 2018, 79% of people living with HIV (PLHIV) knew their status; 78% of those who knew their status were on ART; and, among people on ART, 86% were virally suppressed. While established evidence-based interventions (EBIs), including voluntary medical male circumcision (VMMC), ART to treat and prevent HIV infection, HIV testing services, and prevention of mother-to-child transmission, have facilitated progress, they have not reached their full potential due to implementation barriers such as HIV-related stigma, mental health co-morbidities, overburdened health facilities and providers, and under-trained staff. We know what interventions work, but we need better evidence on how to implement them with fidelity and overcome real-world barriers, as well as how to ensure utilization and translation of the evidence into policy and practice.

description: We show how multi-walker quantum walks can be implemented in a quantum quincunx created via cavity quantum electrodynamics. The implementation of a quantum walk with a multi-walker opens up the interesting possibility to introduce entanglement and more advanced walks. With different coin tosses and initial states the multi-walker quantum walk shows different probability distributions which deviate strongly from the classical random walks with quadratic enhanced spreadings and localization effects. By introducing decoherence, the transition from quantum walks to the classical versions is observed. We introduce the average fidelity decay as a signature to investigate the decoherence-induced irreversibility of quantum walks.

description: A thin water film evaporating from a cleaved mica substrate undergoes a first-order phase transition between two values of film thickness. During evaporation, the interface between the two phases develops a fingering instability similar to that observed in the Saffman-Taylor problem. The dynamics of the droplet interface is dictated by an infinite number of conserved quantities: all harmonic moments decay exponentially at the same rate. A typical scenario is the nucleation of a dry patch within the droplet domain. We construct solutions of this problem and analyze the toplogical transition occuring when the boundary of the dry patch meets the outer boundary. We show a duality between Laplacian growth and evaporation, and utilize it to explain the behaviour near the transition. We construct a family of problems for which evaporation and Laplacian growth are limiting cases and show that a necessary condition for a smooth topological transition, in this family, is that all boundaries share the same pressure.

description: Bioconcentration tests using the freshwater amphipod Hyalella azteca as an alternative to conventional fish tests have recently received much attention. An appropriate computational model of H. azteca could help in understanding the mechanisms behind bioconcentration, in comparison to the fish as test organism. We here present the first mechanistic model for H. azteca that considers the single diffusive processes in the gills and gut. The model matches with the experimental data from the literature quite well when appropriate physiological information is used. The implementation of facilitated transport was essential for modeling. Application of the model for superhydrophobic compounds revealed binding to organic matter and the resulting decrease in bioavailable fraction as the main reason for the observed counterintuitive decrease in uptake rate constants with increasing octanol/water partition coefficient. Furthermore, estimations of the time needed to reach steady state indicated that durations of more than a month could be needed for compounds with a log Kow > 8, limiting the experimental applicability of the test. In those cases, model-based bioconcentration predictions could be a preferable approach, which could be combined with in vitro biotransformation measurements. However, our sensitivity analysis showed that the uncertainty in determining the octanol/water partition coefficients is a strong source of error for superhydrophobic compounds.

description: The IPsec protocol promised easy, ubiquitous encryption. That has never happened. For the most part, IPsec usage is confined to VPNs for road warriors, largely due to needless configuration complexity and incompatible implementations. We have designed a simple VPN configuration language that hides the unwanted complexities. Virtually no options are necessary or possible. The administrator specifies the absolute minimum of information: the authorized hosts, their operating systems, and a little about the network topology; everything else, including certificate generation, is automatic. Our implementation includes a multitarget compiler, which generates implementation-specific configuration files for three different platforms; others are easy to add.

description: The problem of propagation of photons and massive vector mesons in the presence of Lorenz and CPT invariance violating medium is studied when the parity-odd medium is bounded by a hyperplane separating it from the vacuum. The solutions in both half-spaces are carefully discussed and in the case of space-like boundary stitched on the boundary with help of the Bogolubov transformations provided by the space-like Chern-Simons vector. The presence of two different Fock vacua is shown and the probability amplitude for transmission of particles from vacuum to parity breaking medium is calculated. We have also found classical solutions and showed that the results are consistent with ones obtained by canonical quantization formalism. In the cases, both of entrance to and of escaping from parity-odd medium, the probabilities for reflecting and passing through were found for each polarization using the classical solutions. Finally, the propagator for each polarization is obtained in the momentum space. Boundary effects under consideration are of certain importance for registration of local parity violation in the finite volume of heavy ion fireball and/or of a star with cold axion condensate.

description: We consider one-dimensional inhomogeneous parabolic equations with higher-order elliptic differential operators subject to periodic boundary conditions. In our main result we show that the property of continuous maximal regularity is satisfied in the setting of periodic little-Hölder spaces, provided the coefficients of the differential operator satisfy minimal regularity assumptions. We address parameter-dependent elliptic equations, deriving invertibility and resolvent bounds which lead to results on generation of analytic semigroups. We also demonstrate that the techniques and results of the paper hold for elliptic differential operators with operator-valued coefficients, in the setting of vector-valued functions.

description: We develop a method to extract the shape information of line profiles from discrete kinematic data. The Gauss-Hermite expansion, which is widely used to describe the line of sight velocity distributions extracted from absorption spectra of elliptical galaxies, is not readily applicable to samples of discrete stellar velocity measurements, accompanied by individual measurement errors and probabilities of membership. We introduce two parameter families of probability distributions describing symmetric and asymmetric distortions of the line profiles from Gaussianity. These are used as the basis of a maximum likelihood estimator to quantify the shape of the line profiles. Tests show that the method outperforms a Gauss-Hermite expansion for discrete data, with a lower limit for the relative gain of approx 2 for sample sizes N approx 800. To ensure that our methods can give reliable descriptions of the shape, we develop an efficient test to assess the statistical quality of the obtained fit. As an application, we turn our attention to the discrete velocity datasets of the dwarf spheroidals of the Milky Way. In Sculptor, Carina and Sextans the symmetric deviations are consistent with velocity distributions more peaked than Gaussian. In Fornax, instead, there is an evolution in the symmetric deviations of the line profile from a peakier to more flat-topped distribution on moving outwards. These results suggest a radially biased orbital structure for the outer parts of Sculptor, Carina and Sextans. On the other hand, tangential anisotropy is favoured in Fornax. This is all consistent with a picture in which Fornax may have had a different evolutionary history to Sculptor, Carina and Sextans.

description: This study investigated the effect of shyness and loneliness on school activity participations of high school students. In this study, 200 high school students from Basic Education High School, Tada-U, in Tada-U Township participated as samples. Descriptive research design and survey method were used. As the research instruments, Revised Cheek and Buss Shyness Scale (RCBS) developed by Cheek & Buss (1981), University of California Los Angeles Loneliness Scale (UCLA) developed by Russell, Peplau & Ferguson (1978) and Evaluation Record for Monthly School Activities Participation were used. Results showed that there was a significant difference in students’ shyness by gender (p<0.001). Male students seem to be shyer than female students. However, there was no significant difference in students’ shyness by Grade. Moreover, there was a significant difference in students’ loneliness by gender (p<0.01). Female students seem to be lonelier than male students in their daily livings. However, there was no significant difference in students’ loneliness by grade. In school activity participation, although there was no difference by gender, it was found by grade. Grade 10 students participated more than Grade 11 students. Finally, it was found that students’ school activity participation was negatively moderately correlated with shyness and loneliness. Based on the findings, it is hoped that the teacher trainers will get some ideas to reduce the shyness and loneliness of their students.

description: Since World War II, inward foreign direct investment (IFDI) has played an important role in Austria, contributing substantially to overall investment. Austria's IFDI stock increased every year except in two. The most recent decline occurred in 2008 as a result of the economic and financial crisis. In fact, valuation adjustments led to a fall of the country's IFDI stock by 4%. Yet, in real terms, as measured by employment, IFDI rose even during 2008, and projections for 2009 suggest renewed growth of the country's IFDI stock. This short Profile highlights a number of stylized facts on IFDI and describes the country's FDI policy environment.
Quasi-stationary simulations of the contact process on quenched networks

description: We present high-accuracy quasi-stationary (QS) simulations of the contact process in quenched networks, built using the configuration model with both structural and natural cutoffs. The critical behavior is analyzed in the framework of the anomalous finite size scaling which was recently shown to hold for the contact process on annealed networks. It turns out that the quenched topology does not qualitatively change the critical behavior, leading only (as expected) to a shift of the transition point. The anomalous finite size scaling holds with exactly the same exponents of the annealed case, so that we can conclude that heterogeneous mean-field theory works for the contact process on quenched networks, at odds with previous claims. Interestingly, topological correlations induced by the presence of the natural cutoff do not alter the picture.

description: In the 2000s, Russia became a significant host for inward foreign direct investment (IFDI). But its investment climate problems, especially corruption, do not allow Russia to exploit its locational advantages to the full. Russia attracts mainly European investors in a rather narrow range of industries (although the share of mining is decreasing) and regions (mainly in Moscow, St. Petersburg and oil-rich Sakhalin). However, even during the crisis, a new industrial cluster has developed near Kaluga and some large mergers and acquisitions (M&As) and greenfield projects have been realized outside the Central and North-West federal districts. Russia is trying to diversify the structure and geography of IFDI using incentives (e.g. in special economic zones).

description: Traditionally, TCP has been considered unfriendly for real-time applications. Nonetheless, popular applications such as Skype use TCP due to the deployment of NATs and firewalls that prevent UDP traffic. This observation motivated us to study the delay performance of TCP for real-time media flows using an analytical model and experiments. The results obtained yield the working region for VoIP and live video streaming applications and guidelines for delay-friendly TCP settings. Further, our research indicates that simple application-level schemes, such as packet splitting and parallel connections, can significantly improve the delay performance of real-time TCP flows.

description: Theoretical studies of localization, anomalous diffusion and ergodicity breaking require solving the electronic structure of disordered systems. We use free probability to approximate the ensemble- averaged density of states without exact diagonalization. We present an error analysis that quantifies the accuracy using a generalized moment expansion, allowing us to distinguish between different approximations. We identify an approximation that is accurate to the eighth moment across all noise strengths, and contrast this with the perturbation theory and isotropic entanglement theory.

description: The spectrum of known black-hole solutions to the stationary Einstein equations has been steadily increasing, sometimes in unexpected ways. In particular, it has turned out that not all black-hole-equilibrium configurations are characterized by their mass, angular momentum and global charges. Moreover, the high degree of symmetry displayed by vacuum and electro-vacuum black-hole spacetimes ceases to exist in self-gravitating non-linear field theories. This text aims to review some developments in the subject and to discuss them in light of the uniqueness theorem for the Einstein-Maxwell system.
