Some magnetic systems feature spin textures, real-space patterns in the orientation of spins that can topologically form non-trivial configurations. Among them, a vortex-like spin swirling texture known as a magnetic skyrmion has attracted particular attention. Lattices of skyrmions form in the helimagnet MnSi with a periodicity of 18 nm, which makes them amenable to investigation by Lorentz trans
We characterize the model spaces K in which functions with smooth boundary extensions are dense. It is shown that such approximations are possible if and only if the singular measure associated to the singular inner factor of is concentrated on a countable union of Beurling Carleson sets. In fact, we use a duality argument to show that if there exists a restriction of the associated singular measu
This book constitutes the refereed proceedings of the 14th International Workshop on Post-Quantum Cryptography, PQCrypto 2022, held in College Park, MD, USA, in August 14–18, 2023.The 25 full papers presented in this book were carefully reviewed and selected from 51 submissions. They are categorized in the following topical sections: code-based cryptography; group-action-based cryptography; isogen
The impacts of climate change on rural cultures and livelihoods depend on how the resulting complex biophysical processes may transform people’s land use practices. We argue that research can incorporate local concerns of compound hazards through deterministic rather than probabilistic approaches to better understand the multiple causations involved in such climate change impacts. We apply mixed
Pseudo-random functions are a fundamental building block in many cryptographic applications. In certain scenarios, a weaker notion (where security is restricted to uniformly random input), but more computationally efficient, called weak pseudo-random functions, is sufficient. In this work, we present new differential attacks on the main binary weak pseudo-random function constructions, namely the
Deep learning has shown promise for gaze estimation in Virtual Reality (VR) and other head-mounted applications, but such models are hard to train due to lack of available data. Here we introduce a novel method to train neural networks for gaze estimation using synthetic images that model the light distributions captured in a P-CR setup. We tested our model on a dataset of real eye images from a V
Acquiring and distributing essential information for understanding global biogeochemical interactions between the atmosphere and ecosystems, and how climate-ecosystem feedback loops may change atmospheric composition in the future is a fundamental pre-requisite for societal resilience in view of climate change. Particularly, the detection of trends and periodicity in the presence of greenhouse gas
In this study, we evaluate the performance of modified polysulfone (PSF) ultrafiltration (UF) membranes, which incorporate deep eutectic solvents (DES), in treating stormwater laden with natural organic matter e.g. chemical oxygen demand (COD) and total suspended solids (TSS). We also aim to understand how these organic substances, e.g. COD, TSS, from the water source contribute to the fouling of
Catalogue-based studies are of central importance in seismological research, to investigate the temporal, spatial and size distribution of earthquakes in specified study areas. Methods for estimating the fundamental catalogue parameters like the Gutenberg-Richter (G-R) b-value and the completeness magnitude (Mc) are well established and routinely applied. However, the magnitudes reported in seismi
The Environmental Research Infrastructure (ENVRI) community is a cluster of European research infrastructures focused on the environment and Earth system science. The ENVRI-FAIR project aims to advance the FAIRness of their data and services with emphasis on interoperability and connect the ENVRI community to the European Open Science Cloud (EOSC). In this article, we present a proposal for a scie
European Environmental Research Infrastructures (ENVRIs) on the ESFRI level are core facilities for providing data, research products and services from the four subdomains of Earth system science – Atmosphere, Marine, Solid Earth, and Biodiversity/Terrestrial Ecosystems. The ENVRI Cluster represents the core component of the European environmental research infrastructure landscape, with the ENVRI
This work considers multi-material topology optimization of compliant mechanisms under transient thermal and quasi-static mechanical conditions wherein thermally actuated devices are optimized for different operating conditions. The materials are modeled using finite strain thermo-hyperelasticity and a two way coupling between the energy balance and equilibrium equations is investigated. The desig
As science and technology evolve, interdisciplinary targets are anything but static, introducing additional levels of complexity and challenging further the initiatives to break the barriers to interdisciplinary research. For over a decade the community of the Environmental Research Infrastructures, forming the ENVRI cluster, has been building strong foundations to overcome these challenges and be
The ENVRI-FAIR project brings together the ESFRI environmental research infrastructures (ENVRI) that provide environmental data and services, with the aim of making their resources compliant to the FAIR principles. To achieve this goal , the required work is mostly technical, with the ENVRIs working towards not only improving the FAIRness of their own data and services, but also reflecting their e
The paper investigates the status of general meanings in prepositional semantics. On the basis of a review of the strategies employed in different accounts of prepositions, the paper argues that strict adherence to the notion of general meanings is unfeasible in the field, partly because a purely deductive method of description breaks down as the number of possible oppositions increases. This fail
In the ENVRI-FAIR project brief on implementation of Open Science and EOSC targets the current achievements and planned activities in ENVRI-FAIR are summarised with regard to a) Integration with the EOSC infrastructure b) FAIR principles implementation and repositories c) Technical, semantic, legal and organisational interoperability d) Stewardship of data and e) Cross-cluster collaboration activi
Focused environmental research projects and continuously operating research infrastructures (RIs) designed for monitoring all subdomains of the Earth system contribute to global observing systems and serve as crucial information sources for environmental scientists in their quest for understanding and interpreting the complex Earth System and contribute to global observing systems. The EU funded E
ENVRI-FAIR is the connection of the ESFRI Cluster of Environmental Research Infrastructures (ENVRI) to the European Open Science Cloud (EOSC). The high-impact ambition of ENVRI-FAIR is to establish the technical preconditions for the successful implementation of a virtual, federated machine-to-machine interface to access environmental data and services provided by the contributing ENVRIs. This int
The physical and chemical changes of a waste mixture consist ing of mumcipal solid waste (MSW) and sewage sludge were investigated during the anaerobic waste stablilization phases of the mixture. The emphasis of this study was the behavior of heavy metals. The waste was deposited in a test cell in 1973. It was found that the waste mass decreased by about 30% (wt) during the years 1973 to 1993 and
