description: Tomographic SAR (TomoSAR) inversion of urban areas is an inherently sparse reconstruction problem and, hence, can be solved using compressive sensing (CS) algorithms. This paper proposes solutions for two notorious problems in this field: 1) TomoSAR requires a high number of data sets, which makes the technique expensive. However, it can be shown that the number of acquisitions and the signal-to-noise ratio (SNR) can be traded off against each other, because it is asymptotically only the product of the number of acquisitions and SNR that determines the reconstruction quality. We propose to increase SNR by integrating non-local estimation into the inversion and show that a reasonable reconstruction of buildings from only seven interferograms is feasible. 2) CS-based inversion is computationally expensive and therefore barely suitable for large-scale applications. We introduce a new fast and accurate algorithm for solving the non-local L1-L2-minimization problem, central to CS-based reconstruction algorithms. The applicability of the algorithm is demonstrated using simulated data and TerraSAR-X high-resolution spotlight images over an area in Munich, Germany.

description: Social Media (SM) has become a popular medium for individuals to share their opinions on various topics, including politics, social issues, and daily affairs. During controversial events such as political elections, active users often proclaim their stance and try to persuade others to support them. However, disparities in participation levels can lead to misperceptions and cause analysts to misjudge the support for each side. For example, current models usually rely on content production and overlook a vast majority of civically engaged users who passively consume information. These “silent users” can significantly impact the democratic process despite being less vocal. Accounting for the stances of this silent majority is critical to improving our reliance on SM to understand and measure social phenomena. Thus, this study proposes and evaluates a new approach for silent users’ stance prediction based on collaborative filtering and Graph Convolutional Networks, which exploits multiple relationships between users and topics. Furthermore, our method allows us to describe users with different stances and online behaviors. We demonstrate its validity using real-world datasets from two related political events. Specifically, we examine user attitudes leading to the Chilean constitutional referendums in 2020 and 2022 through extensive Twitter datasets. In both datasets, our model outperforms the baselines by over 9% at the edge- and the user level. Thus, our method offers an improvement in effectively quantifying the support and creating a multidimensional understanding of social discussions on SM platforms, especially during polarizing events.

We weaken the self-consistence condition (L. Parker, J. Z. Simon, Phys. Rev. {D47}(1993),{1339}). Quantum corrections are expressed as contributions to the effective equation of state. We show that the empty space-time is stable within the class of radiation-filled expanding universes with no order reduction of the field equations.

description: Young migrants and refugees provide important inputs concerning production and social reproduction mechanisms (care work) that reproduce unequal but highly profitable patterns of accumulation around the world. The expansion of globalisation and neoliberalism has deepened such social dynamics, leading to a “multiplication of labour.” The diversification and heterogenization of migrant labour within neoliberal frameworks raise ethical and human rights concerns, including issues related to fair wages, working conditions, and access to social protections. After a neoliberal era in Latin America, the emergence of post-development politics in the region led to increased efforts to address the needs of these populations. This article seeks to contribute to debates about “differential inclusion” in South–South migration and access to labour and social protection by analysing a specific case study of young Venezuelans, a recently growing phenomenon that has a great impact on the region. Ecuador is noteworthy because it hosts one of the largest populations of Venezuelan migrants and refugees and has adopted a human rights perspective in conjunction with public investments in social policy, health, and education. Despite efforts to legalize the work status of Venezuelan migrants, a more restrictive policy began to be implemented in 2019 that limited their access to formal labour and social protection. Within these complex dynamics of differential inclusion, instead of seeing these young migrants and refugees as victims, we analyse their resilience strategies of accessing social provisions while coping with informality and irregular status, as well as conditions of multiplication of labour. Using four real-life stories as examples taken from a larger ethnographic study, we illustrate how dynamics of differential inclusion intersect with the gender, age, and legal status of young Venezuelans in Ecuador. The case studies are complemented with structural explanations from 6,000 household surveys collected between 2017 and 2020.

description: Space Monitoring Data Center (SMDC) of SINP MSU is one of the several centers in the world that collects data on the radiational conditions in near-Earth orbit from various Russian (Lomonosov, Electro-L1, Electro-L2, Meteor-M1, Meteor-M2, etc.) and foreign (GOES 13, GOES 15, ACE, SDO, etc.) satellites. The primary purposes of SMDC are: aggregating heterogeneous data from different sources; providing a unified interface for data retrieval, visualization, analysis, as well as development and testing new space weather models; and controlling the correctness and completeness of data. Space weather models rely on data provided by SMDC to produce forecasts. Therefore, monitoring the whole data processing cycle is crucial for further success in the modelling of physical processes in near-Earth orbit based on the collected data. To solve the problem described above, we have developed a framework called Live Monitor at SMDC. Live Monitor allows watching all stages and program components involved in each data processing cycle. All activities of each stage are logged by Live Monitor and shown in real-time on a web interface. When an error occurs, a notification message will be sent to satellite operators via email and the Telegram messenger service so that they could take measures in time. The Live Monitor's API can be used to create a customized monitoring service with minimum coding.

description: Using a Dirac-Heisenberg Hamiltonian with biquadratic exchange interactions, we study the effect of iron disproportionation on the magnetic ordering, and describe the first-order magnetic transition occurring in the perovskite Sr_{2}LaFe_{3}O_{9}. Upon fitting the experimental data, we give an estimate of the exchange integrals for the antiferromagntic and ferromagnetic interactions, in agreement with previous works on kindered compounds. Spin-wave theory yields a magnon spectrum with a gapless antiferromagnetic mode together with two gapped ferromagnetic ones.

description: Calcium orthophosphates (CaPs), as hydroxyapatite (HAP) in bones and teeth are the most important biomineral for humankind. While clusters in CaP nucleation have long been known, their speciation and mechanistic pathways to HAP remain debated. Evidently, mineral nucleation begins with two ions interacting in solution, fundamentally underlying solute clustering. Here, we explore CaP ion association using potentiometric methods and computer simulations. Our results agree with literature association constants for Ca2+ and H2PO4−, and Ca2+ and HPO42-, but not for Ca2+ and PO43− ions, which previously has been strongly overestimated by two orders of magnitude. Our data suggests that the discrepancy is due to a subtle, premature phase separation that can occur at low ion activity products, especially at higher pH. We provide an important revision of long used literature constants, where association of Ca2+ and PO43− actually becomes negligible below pH 9.0, in contrast to previous values. Instead, [CaHPO4]0 dominates the aqueous CaP speciation between pH ~6–10. Consequently, calcium hydrogen phosphate association is critical in cluster-based precipitation in the near-neutral pH regime, e.g., in biomineralization. The revised thermodynamics reveal significant and thus far unexplored multi-anion association in computer simulations, constituting a kinetic trap that further complicates aqueous calcium phosphate speciation.

A complete classification of spherically symmetric perfect fluid similarity solutions

description: We classify all spherically symmetric perfect fluid solutions of Einstein's equations with equation of state p/mu=a which are self-similar in the sense that all dimensionless variables depend only upon z=r/t. For a given value of a, such solutions are described by two parameters and they can be classified in terms of their behaviour at large and small distances from the origin; this usually corresponds to large and small values of z but (due to a coordinate anomaly) it may also correspond to finite z. We base our analysis on the demonstration that all similarity solutions must be asymptotic to solutions which depend on either powers of z or powers of lnz. We show that there are only three similarity solutions which have an exact power-law dependence on z: the flat Friedmann solution, a static solution and a Kantowski-Sachs solution (although the latter is probably only physical for a<0). For a>1/5, there are also two families of solutions which are asymptotically (but not exactly) Minkowski: the first is asymptotically Minkowski as z tends to infinity and is described by one parameter; the second is asymptotically Minkowski at a finite value of z and is described by two parameters. A complete analysis of the dust solutions is given, since these can be written down explicitly and elucidate the link between the z>0 and z<0 solutions. Solutions with pressure are then discussed in detail; these share many of the characteristics of the dust solutions but they also exhibit new features.

description: In a recent work, a contribution to the Nernst current of a Dirac or Weyl semimetal coming from the conformal anomaly was reported. Being originated from an anomaly - a vacuum contribution -, a non-zero transport coefficient was predicted at zero temperature and chemical potential. In this work we perform a Kubo formula calculation of the thermoelectrical coefficient and confirm that the result agrees with the quantum field theory estimation in the limit of zero temperature and chemical potential. For finite chemical potential μ around μ = 0 the transverse Seebeck coefficient shows a plateau indicating that only the zero conformal Landau levels contributes to this intrinsic effect. This result opens the way to the experimental observation of a geometric anomaly which is much harder to explore than the standard chiral anomaly.

The dataset encompasses detailed information on wild flora diversity, grain yield, associated management practices, soil texture and weather during the growing period. Wild flora diversity was recorded by conducting a vegetation survey in 1 × 2 m sample plots. Grain yield was determined at the crop maturity stage, with full plots harvested in Spain, while samples were taken in Croatia and Tunisia. Environmental variables were via laboratory analysis or bottle testing of soil samples and analysis of local weather data. The comprehensiveness of the dataset, including all relevant agroecological information, enables other researchers to employ the dataset for various statistical analyses of agroecosystem processes, such as plant-environment interactions or biodiversity-yield trade-off analysis.

description: Dynamics of magnetic bubbles in planar ferromagnets described by the Landau-Lifshitz equation with dissipation is analyzed. The pure O(3) sigma model has static multisoliton solutions, characterized by a number of parameters. The parameters describe a finite dimensional manifold. A small perturbation of energy functional with respect to the sigma model forces solitons to move. Multisoliton dynamics is effectively reduced to a flow in the parameter space.

description: We study various properties of composition operators acting between generalized Fock spaces $\mathcal{F}_φ^p$ and $\mathcal{F}_φ^q$ with weight functions $φ$ grow faster than the classical Gaussian weight function $\frac{1}{2}|z|^2$ and satisfy some mild smoothness conditions. We have shown that if $p\neq q,$ then the composition operator $C_ψ: \mathcal{F}_φ^p \to \mathcal{F}_φ^q $ is bounded if and only if it is compact. This result shows a significance difference with the analogous result for the case when $C_ψ$ acts between the classical Fock spaces or generalized Fock spaces where the weight functions grow slower than the Gaussian weight function. We further described the Schatten $\mathcal{S}_p(\mathcal{F}_φ^2)$ class, normal, unitary, cyclic and supercyclic composition operators. As an application, we characterized the compact differences, the isolated and essentially isolated points, and connected components of the space of the operators under the operator norm topology.

description: Water kefir is a convenient dairy-free alternative to dairy-based fermented beverages. It is prepared by fermenting a sucrose solution with fresh and dried fruits using water kefir grains, and demineralized whey can be used in water kefir production. This review describes current knowledge on water kefir production and its health effects. The main aims of this paper are to focus on the microbial composition, potential health-promoting properties, limitations in human consumption, and challenges in the production of water kefir. Water kefir grains and substrates, including brown sugar, dried and fresh fruits, vegetables, and molasses, used in the production influence the fermentation characteristics and composition of water kefir. Lactic acid bacteria, acetic acid bacteria, and yeasts are the microorganisms involved in the fermentation process. Lactobacillus species are the most common microorganisms found in water kefir. Water kefir contains various bioactive compounds that have potential health benefits. Water kefir may inhibit the growth of certain pathogenic microorganisms and food spoilage bacteria, resulting in various health-promoting properties, including immunomodulatory, antihypertensive, anti-inflammatory, anti-ulcerogenic, antiobesity, hypolipidemic, and hepatoprotective activities.

description: The aviation industry faces an urgent need to adopt sustainable aviation fuels for significant decarbonization. Power-to-Liquid (PtL) fuel is considered a potential game changer, but questions remain about the wider economic impacts of introducing PtL fuel in the aviation sector. This paper examines the economic impacts of introducing PtL fuel blending quotas along with a price policy consisting of a kerosene tax and PtL fuel subsidies for the case of Germany. Based on a detailed supply chain analysis, we apply a social accounting matrix and a computable general equilibrium model to take into account both, the production and utilization perspectives of PtL jet fuel. Our results show that the influence of low blending quotas is mainly limited to the aviation sector, with a 10 % blending quota increasing consumer prices by 7.9 % and reducing aviation industry output by 3.1 %. When quota levels increase, however, the effects go beyond the air transport system. On inter-sectoral level, we identify three main patterns: First, industries that substantially contribute to the PtL fuel supply chain, such as metal products and electrical equipment, see increasing levels in both, domestic production, and imports. Second, aviation upstream industries like transport infrastructure and aircraft production see reduced domestic production and imports. Third, aviation downstream industries, such as delivery services and travel agencies, see substitution effects, where imports partly replace domestic output. Macroeconomic indicators are affected negatively by the quota scenarios, but the relative impact is low as the maximum decrease in the gross domestic product (GDP) does not exceed 0.35 %. PtL fuel production subsidies can largely mitigate the decrease in aviation demand but come at the cost of a stronger reduction in the GDP and government income. Moreover, the sensitivity analysis emphasizes that various assumptions and parameters, such as the cost projections of PtL fuel, import options, and elasticities of demand, affect the intensity of economic consequences. Our analysis implies the trade-offs of policymaking between sectoral and macroeconomic interests in the context of sustainable fuels. The main contribution of this study is the investigation of the broader economic effects resulting from the adoption of PtL fuels in aviation. In particular, the production as well as the utilization perspective are considered simultaneously in this study.

description: The diffusion of AFV’s is comparatively high in Sri Lanka, even though the uncertainties and negative consequences of owning them are perceived to be high. This contradicts the theory of perceived risk which postulates that when customers perceive the negative consequences of purchasing, goal driven purchase intention should weaken. Hence, the purpose of this paper is to examine the effect of perceived risk on the relationships between key purchasing determinants and purchase intention of alternative fuel vehicles in Sri Lanka. This study examines this unexpected local consumer behaviour through the lens of the Theory of Perceived Risk and the study employed structured questionnaires to gather primary data from the sample utilizing a convenience sampling technique. It employed two step Partial Least Squares (PLS)-Structural Equation Modeling (SEM) to analyze the data, and the analysis revealed that performance expectancy facilitating conditions (FC) are the key determinants of the purchase intention of AFV customers in Sri Lanka. Furthermore, perceived risk was found to moderate the relationships between these determinants and the purchase intention of customers who plan to invest in AFVs.

description: Compactifying M-theory on a manifold of $G_2$ holonomy gives a UV complete 4D theory. It is supersymmetric, with soft supersymmetry breaking via gaugino condensation that simultaneously stabilizes all moduli and generates a hierarchy between the Planck and the Fermi scale. It generically has gauge matter, chiral fermions, and several other important features of our world. Here we show that the theory also contains a successful inflaton, which is a linear combination of moduli closely aligned with the overall volume modulus of the compactified $G_2$ manifold. The scheme does not rely on ad hoc assumptions, but derives from an effective quantum theory of gravity. Inflation arises near an inflection point in the potential which can be deformed into a local minimum. This implies that a de Sitter vacuum can occur in the moduli potential even without uplifting. Generically present charged hidden sector matter generates a de Sitter vacuum as well.

description: In order to distinguish between regular and chaotic planetary orbits we apply a new technique called MEGNO in a wide neighbourhood of orbital parameters determined using standard two-body Keplerian fits for HD 12661, HD 38529, HD 37124 and HD 160691 planetary systems. We show that the currently announced orbital parameters place these systems in very different situations from the point of view of dynamical stability. While HD 38529 and HD 37124 are located within large stability zones in the phase space around their determined orbits, the preliminary orbits in HD 160691 are highly unstable. The orbital parameters of the HD 12661 planets are located in a border region between stable and unstable dynamical regimes, so while its currently determined orbital parameters produce stable regular orbits, a minor change within the margin of error of just one parameter may result in a chaotic dynamical system.

description: Recently, the synthesis of oxidized holey graphene with the chemical formula C2O has been reported (J. Am. Chem. Soc. 2024, 146, 4532). We herein employed a combination of density functional theory (DFT) and machine learning interatomic potential (MLIP) calculations to investigate the electronic, optical, mechanical and thermal properties of the C2O monolayer, and compared our findings with those of its C2N counterpart. Our analysis shows that while the C2N monolayer exhibits delocalized π-conjugation and shows a 2.47 eV direct-gap semiconducting behavior, the C2O counterpart exhibits an indirect gap of 3.47 eV. We found that while the C2N monolayer exhibits strong absorption in the visible spectrum, the initial absorption peaks in the C2O lattice occur at around 5 eV, falling within the UV spectrum. Notably, we found that the C2O nanosheet presents significantly higher tensile strength compared to its C2N counterpart. MLIP-based calculations show that at room temperature, the C2O nanosheet can exhibit remarkably high tensile strength and lattice thermal conductivity of 42 GPa and 129 W/mK, respectively. The combined insights from DFT and MLIP-based results provide a comprehensive understanding of the electronic and optical properties of C2O nanosheets, suggesting them as mechanically robust and highly thermally conductive wide bandgap semiconductors.
