description: Numerous processor cores based on the popular RISC-V Instruction Set Architecture have been developed in the past few years and are freely available. The same applies for RISC-V ecosystems that allow to implement System-on-Chips with RISC-V processors on ASICs or FPGAs. However, so far only very little concepts and implementations for fault tolerant RISC-V processors are existing. This inhibits the use of RISC-V for safety-critical applications (as in the automotive domain) or within radiation environments (as in the aerospace domain). This work enhances the existing implementations Rocket and BOOM with a generic Error Correction Code (ECC) protected memory as a first step towards fault tolerance. The impact of the ECC additions on performance and resource utilization are discussed.

description: In this article, we study several closely related invariants associated to Dirac operators on odd-dimensional manifolds with boundary with an action of the compact group $H$ of isometries. In particular, the equality between equivariant winding numbers, equivariant spectral flow, and equivariant Maslov indices is established. We also study equivariant $η$-invariants which play a fundamental role in the equivariant analog of Getzler's spectral flow formula. As a consequence, we establish a relation between equivariant $η$-invariants and equivariant Maslov triple indices in the splitting of manifolds.

description: We address a possibility of creating soliton states in oblate binary-fermionic clouds in the framework of the density-functional theory, which includes the spin-orbit coupling (SOC) and nonlinear attraction between spin-up and down-polarized components of the spinor wave function. In the limit when the inter-component attraction is much stronger than the effective intra-component Pauli repulsion, the resulting model also represents a system of Gross-Pitaevskii equations for a binary Bose-Einstein condensate including the SOC effect. We show that the model gives rise to two-dimensional quiescent composite solitons in free space. A stability region is identified for solitons of the mixed-mode type (which feature mixtures of zero-vorticity and vortical terms in both components), while solitons of the other type, semi-vortices (with the vorticity carried by one component) are unstable. Due to breaking of the Galilean invariance by SOC, the system supports moving solitons with velocities up to a specific critical value. Collisions between moving solitons are briefly considered too. The collisions lead, in particular, to a quasi-elastic rebound, or an inelastic outcome, which features partial merger of the solitons.

The strong CP problem solved by itself due to long-distance vacuum effects

description: The vacuum of quantum chromodynamics has an incredibly rich structure at the nonperturbative level, which is intimately connected with the topology of gauge fields, and put to a stringent test by the strong CP problem. We investigate the long-distance properties of the theory in the presence of a topological $\theta$ term. This is done on the lattice, using the gradient flow to isolate the long-distance modes in the functional integral measure and tracing it over successive length scales. We find that the color fields produced by quarks and gluons are screened for vacuum angles $|\theta| > 0$, thus providing a natural solution of the strong CP problem.

description: We report that the local Ising anisotropy in pyrochlore oxides - the crucial requirement for realizing the spin-ice state - can be broken by means of high magnetic fields. For the case of the well-established classical spin-ice compound Ho$_2$Ti$_2$O$_7$ the magnetization exceeds the angle-dependent saturation value of the Ising limit using ultra-high fields up to 120 T. However, even under such extreme magnetic fields full saturation cannot be achieved. Crystal-electric-field calculations reveal that a level crossing for two of the four ion positions leads to magnetization steps at 55 and 100 T. In addition, we show that by using a field sweep rate in the range of the spin-relaxation time the dynamics of the spin system can be probed. Exclusively at 25 ns/T a new peak of the susceptibility appears around 2 T. We argue, this signals the cross-over between spin-ice and polarized correlations.

description: A novel magnetic reduced graphene oxide nanoribbons (Fe3O4 @RGONRs) composite was prepared and applied as an adsorbent of magnetic solid-phase extraction (MSPE) for the determination of four bisphenol endocrine disrupters in three carbonated beverages coupled with high-performance liquid chromatography (HPLC). The prepared Fe3O4@RGONRs composite was characterized by transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometry, nitrogen adsorption-desorption isotherms and zeta potential analysis. Fe3O4@RGONRs composite possessed an abundant π-electron system and interacted with the analytes by π-π stacking, hydrophobic interactions, and hydrogen bond. The MSPE parameters, including the mass of adsorbent, sample solution pH, extraction time, ionic strength, desorption solvent and desorption time, were evaluated. Under the optimal conditions, the proposed Fe3O4@RGONRs-based MSPE method exhibited good linearity with determination coefficients (R2) between 0.9994 and 1000 from 1.6 to 1000 µg L−1, low limits of detection from 0.33 to 0.87 µg L−1, and suitable accuracy with spiked recoveries from 81.88% to 115.73%. The excellent analytical performance, along with suitable batch-to-batch reproducibility and reusability, suggest potential applications in the field of sample pretreatment.

description: The synthesis and characterization of three novel N2O-donor ligands containing the group 4-[1-β-d-2,3,4,6-tetra-O-acetyl-galactosyl)]benzaldehyde are presented. The insertion of this group was designed to increase the absorption of the prodrug in tumor cells, and is part of an ongoing work in our group with tridentate ligands to develop potential cobalt(III) prodrugs. The synthetic route described here allowed the isolation of pure ligands with yields ranged 81-89%. Finally, compounds were characterized by IR, NMR and HRMS (ESI+).

description: We present the results of time-series photometric analysis of 15106 A-K type stars observed by the Kepler space mission. We identified 513 new rotational variables and measured their starspot rotation periods as a function of spectral type and discuss the distribution of their amplitudes. We examined the well-established period-colour relationship that applies to stars of spectral types F5-K for all of these rotational variables and, interestingly, found that a similar period-colour relationship appears to extend to stars of spectral types A7 to early-F too. This result is not consistent with the very foundation of the period-colour relationship. We have characterized 350 new non-radial pulsating variables such as A- and F-type candidate $δ$ Scuti, $γ$ Doradus and hybrid stars, which increases the known candidate non-radial pulsators in the Kepler field significantly, by $\sim$20\%. The relationship between two recently constructed observables, $Energy$ and $Efficiency$, was also studied for the large sample of non-radial pulsators, which shows that the distribution in the logarithm of $Energy$ ($\log(En)$) can be used as a potential tool to distinguish between the non-radial pulsators, to some extent. Through visual inspection of the light curves and their corresponding frequency spectra, we found 23 new candidate red giant solar-like oscillators not previously reported in the literature. The basic physical parameters such as masses, radii and luminosities of these solar-like oscillators were also derived using asteroseismic relations.

The Eikonal Equation in Flat Space: Null Surfaces and Their Singularities I

description: The level surfaces of solutions to the eikonal equation define null or characteristic surfaces. In this note we study, in Minkowski space, properties of these surfaces. In particular we are interested both in the singularities of these ``surfaces'' (which can in general self-intersect and be only piece-wise smooth) and in the decomposition of the null surfaces into a one parameter family of two-dimensional wavefronts which can also have self-intersections and singularities. We first review a beautiful method for constructing the general solution to the flat-space eikonal equation; it allows for solutions either from arbitrary Cauchy data or for time independent (stationary) solutions of the form S=t-S_{0}(x,y,z). We then apply this method to obtain global, asymptotically spherical, null surfaces that are associated with shearing ("bad") two-dimensional cuts of null infinity; the surfaces are defined from the normal rays to the cut. This is followed by a study of the caustics and singularities of these surfaces and those of their associated wavefronts. We then treat the same set of issues from an alternative point of view, namely from Arnold's theory of generating families. This treatment allows one to deal (parametrically) with the regions of self-intersection and non-smoothness of the null surfaces, regions which are difficult to treat otherwise. Finally we generalize the analysis of the singularities to families of solutions of the eikonal equation.

description: Recent research discusses concepts of infield changes to overcome the drawbacks of conventional lab-based system design processes. In this paper, we evaluate the concept of controlled change by applying it to a demonstration of a potential future space exploration scenario with mobile robots. The robots are capable of executing several image computations for exploration, object detection and pose estimation, which can be allocated to both FPGA-and processor resources of a System-on-Chip. The demonstrator addresses three scenarios which cover application-, environment-, and platform change. The system adapts itself to any of the named changes. This capability can increase the autonomy of future space missions. Exemplary, the demonstrator executes adaption of applications during operation to fulfill the mission goals, adaption of reliability under changing environment conditions, and adaption to sensor failure.

description: The LiLa project consists in the creation of a Knowledge Base of linguistic resources for Latin
 based on the Linked Data framework and aimed at reaching interoperability between them. To
 this goal, LiLa integrates all types of annotation applied to a particular word/text into a common
 representation where all linguistic information conveyed by a specific linguistic resource becomes
 accessible. The recent inclusion in the Knowledge Base of information on word formation raised
 a number of theoretical and practical issues concerning its treatment and representation. This
 paper discusses such issues, presents how they were addressed in the project and describes a
 number of use-case scenarios that employ the information on word formation made available in
 the LiLa Knowledge Base.
Secular spin-axis dynamics of exoplanets

description: Context: Seasonal variations and climate stability of a planet are very sensitive to the planet obliquity and its evolution. This is of particular interest for the emergence and sustainability of land-based life, but orbital and rotational parameters of exoplanets are still poorly constrained. Numerical explorations usually realised in this situation are thus in heavy contrast with the uncertain nature of the available data. Aims: We aim to provide an analytical formulation of the long-term spin-axis dynamics of exoplanets, linking it directly to physical and dynamical parameters, but still giving precise quantitative results if the parameters are well known. Together with bounds for the poorly constrained parameters of exoplanets, this analysis is designed to allow a quick and straightforward exploration of the spin-axis dynamics. Methods: The long-term orbital solution is decomposed in quasi-periodic series and the spin-axis Hamiltonian is expanded in powers of eccentricity and inclination. Chaotic zones are measured by the resonance overlap criterion. Bounds for the poorly known parameters of exoplanets are obtained from physical grounds (rotational breakup) and dynamical considerations (equipartition of AMD). Results: This method gives accurate results when the orbital evolution is well known. The chaotic zones for planets of the Solar System can be retrieved in details from simple analytical formulas. For less constrained planetary systems, the maximal extent of the chaotic regions can be computed, requiring only the mass, the semi-major axis and the eccentricity of the planets present in the system. Additionally, some estimated bounds of the precession constant allow to classify which observed exoplanets are necessarily out of major spin-orbit secular resonances (unless the precession rate is affected by the presence of massive satellites).

The developed method provides good to excellent yields of various pyrrolidinones in environmentally friendly conditions. Furthermore, this efficient protocol displays a combination of the synthetic advantage of one-pot multicomponent reaction with ecological benefits and convenience of a mechanochemical procedure.
Detection of planetary signals by reflected light of the host star using the autocorrelation of spectra

description: We consider an alternative to the cross-correlation function (CCF), that uses the autocor- relation function (ACF), to measure in spectra the reflected light of the stars by their planetary companion. The objective of this work is to assess and analyse the efficiency of the ACF in detecting planetary signals by a detection of reflected light. To do so, we first compare the ACF and the CCF using artificial spectra containing a planetary signal. We then use the ACF to analyse spectra of the 51 Peg + 51 Peg b system and compare our results with those obtained by Martins et al. (2015) who previously analysed the same system using the CCF. The functionalities of the ACF and the way it is implemented are similar to that of the CCF. One of the main advantages of the ACF is the fact that, unlike the CCF, no weighted binary mask is required. This makes the ACF easier to use. The results related to simulated spectra showed that the ACF allowed us to decrease the boundary condition threshold for the use of spectra compared to the CCF so that more data could be used to recover the planetary signal. For the 51 Peg b planet, we achieved a detection significance of 5.52 σnoise with the ACF compared to 3.70 σnoise with the CCF (Martins et al. 2015). We conclude that the ACF has the potential to become a prominent technique in detecting exoplanets considering its efficiency, ease of use and rapid execution time.

description: ARM-FPGA coupled platforms allow accelerating the computation of specific algorithms by executing them in the FPGA fabric. Several computation steps of our case study for a stereo vision application have been accelerated by hardware implementations. Dynamic Partial Reconfiguration places these hardware tasks in the programmable logic at appropriate times. For an efficient scheduling, it needs to be decided when and where to execute a task. Although there already exist hardware/software scheduling strategies and algorithms, none exploit all possible optimization techniques: re-use, prefetching, parallelization, and pipelining of hardware tasks. The scheduling algorithm proposed in this paper takes this into account and optimizes for the objectives latency/throughput and power/energy.

description: Consider the random Cayley graph of a finite Abelian group $G$ with respect to $k$ generators chosen uniformly at random, with $1 \ll \log k \ll \log |G|$. Draw a vertex $U \sim \operatorname{Unif}(G)$.
 We show that the graph distance $\operatorname{dist}(\mathsf{id},U)$ from the identity to $U$ concentrates at a particular value $M$, which is the minimal radius of a ball in $\mathbb Z^k$ of cardinality at least $|G|$, under mild conditions. In other words, the distance from the identity for all but $o(|G|)$ of the elements of $G$ lies in the interval $[M - o(M), M + o(M)]$. In the regime $k \gtrsim \log |G|$, we show that the diameter of the graph is also asymptotically $M$. In the spirit of a conjecture of Aldous and Diaconis (1985), this $M$ depends only on $k$ and $|G|$, not on the algebraic structure of $G$.
 Write $d(G)$ for the minimal size of a generating subset of $G$. We prove that the order of the spectral gap is $|G|^{-2/k}$ when $k - d(G) \asymp k$ and $|G|$ lies in a density-$1$ subset of $\mathbb N$ or when $k - 2 d(G) \asymp k$. This extends, for Abelian groups, a celebrated result of Alon and Roichman (1994).
 The aforementioned results all hold with high probability over the random Cayley graph.

In addition, it analyses the software developed in previous Shift2Rail projects to determine whether the functions developed in RIDE2RAIL can be integrated into existing artefacts. To determine the requirements and the specifications of the RIDE2RAIL modules, the deliverable follows a rather standard software engineering approach, and it first identifies the external actors with which RIDE2RAIL modules will interact; then, it presents a set of use cases that provide an initial understanding of the functions to be realised in the project; from the use cases, a set of requirements are derived, then an initial model of the components to be developed in the project and their interfaces is provided in the form of a UML model.

description: The vast work in Deep Learning (DL) has led to a leap in image denoising research. Most DL solutions for this task have chosen to put their efforts on the denoiser's architecture while maximizing distortion performance. However, distortion driven solutions lead to blurry results with sub-optimal perceptual quality, especially in immoderate noise levels. In this paper we propose a different perspective, aiming to produce sharp and visually pleasing denoised images that are still faithful to their clean sources. Formally, our goal is to achieve high perceptual quality with acceptable distortion. This is attained by a stochastic denoiser that samples from the posterior distribution, trained as a generator in the framework of conditional generative adversarial networks (CGAN). Contrary to distortion-based regularization terms that conflict with perceptual quality, we introduce to the CGAN objective a theoretically founded penalty term that does not force a distortion requirement on individual samples, but rather on their mean. We showcase our proposed method with a novel denoiser architecture that achieves the reformed denoising goal and produces vivid and diverse outcomes in immoderate noise levels.

description: We calculate the Aslamazov-Larkin term of the conductivity in the presence of a magnetic field applied along the c-axis from the time-dependent Ginzburg-Landau equation perturbatively using two approaches. In the first a uniform electric field is explicitly applied; in the second the Kubo formula is used to extract the linear response. The former yields a version of the flux-flow formula for the uniform ab-plane conductivity, sigma_{xx}(k=0), that holds to all orders of perturbation theory. Obtaining the same result from the Kubo formula requires considerable cancellation of terms. We also use the Kubo calculation to examine the nonlocal ab-plane conductivity, sigma_{xx}( k \neq 0) (where the cancellations no longer occur), as well as the nonlocal c-axis conductivity sigma_{zz}( k \neq 0), and look for the perturbative precursors of the growing viscous length scales. In addition, we consider the effects of weak disorder -- both uncorrelated (point defects) and correlated (columnar and planar defects).

description: Algorithms with operations on large regular data structures such as image processing can be highly accelerated when executed as hardware tasks in an FPGA fabric. The Dynamic Partial Reconfiguration (DPR) feature of new SRAM-based FPGA families allows a dynamic swapping and replacement of hardware tasks during runtime. Particularly embedded systems with processing chains that change over time or that are too large to be implemented in an FPGA fabric in parallel, benefit from DPR. In this paper we present a complete framework for hardware acceleration using DPR in the microkernel based Genode OS. This makes the DPR feature available not only for the high-performance computing field, but also for safety-critical applications. The new framework is evaluated for an exemplary imaging application running on a Xilinx Zynq-7000 SoC.

description: We have clarified the origin of magnetically dead interface layer formed in yttrium iron garnet (YIG) films grown at above 700°C onto gadolinium gallium garnet (GGG) substrate by means of laser molecular beam epitaxy. The diffusion-assisted formation of a Ga-rich region at the YIG / GGG interface is demonstrated by means of composition depth profiling performed by X-ray photoelectron spectroscopy, secondary ion mass spectroscopy and X-ray and neutron reflectometry. Our finding is in sharp contrast to the earlier expressed assumption that Gd acts as a migrant element in the YIG/GGG system. We further correlate the presence of Ga-rich transition layer with considerable quenching of ferromagnetic resonance and spin wave propagation in thin YIG films. Finally, we clarify the origin of the enigmatic low-density overlayer that is often observed in neutron and X-ray reflectometry studies of the YIG / GGG epitaxial system.

description: Field-Programmable Gate Arrays (FPGAs) provide highly flexible platforms to implement sophisticated data processing for scientific space instruments. The dynamic partial reconfiguration (DPR) capability of FPGAs allows it to schedule HW tasks. While this feature adds another dimension of processing power that can be exploited without significantly increasing system complexity and power consumption, there are still several challenges for an efficient DPR use. State-of-the-art concepts concentrate either on resource-efficient implementations at design time or flexible HW task scheduling at runtime. In this paper we propose a balanced algorithm that considers both optimization goals and is well suited for resource-limited space applications.

description: We introduce a model-based reliability estimation to preserve application availability in CPU-FPGA systems exposed to soft errors under varying environment conditions. The estimation is used as an in-system method to select a suitable configuration for changing radiation conditions. This allows systems to autonomously adapt their configuration in order to balance between reliability and performance. Such a self-adaptation goes beyond the state-of-the-art, where adaptation relies on preplanned reactive mode changes. By autonomously evaluating new configurations, our self-adaptation process is capable of increasing the availability by selecting the configuration with the desired application reliabilities for the current environment conditions.
Screening $p$-Hackers: Dissemination Noise as Bait

description: We show that adding noise before publishing data effectively screens $p$-hacked findings: spurious explanations produced by fitting many statistical models (data mining). Noise creates "baits" that affect two types of researchers differently. Uninformed $p$-hackers, who are fully ignorant of the true mechanism and engage in data mining, often fall for baits. Informed researchers, who start with an ex-ante hypothesis, are minimally affected. We show that as the number of observations grows large, dissemination noise asymptotically achieves optimal screening. In a tractable special case where the informed researchers' theory can identify the true causal mechanism with very little data, we characterize the optimal level of dissemination noise and highlight the relevant trade-offs. Dissemination noise is a tool that statistical agencies currently use to protect privacy. We argue this existing practice can be repurposed to screen $p$-hackers and thus improve research credibility.

description: Osterwalder and Schrader introduced a procedure to obtain a (Lorentzian) Hamiltonian quantum theory starting from a measure on the space of (Euclidean) histories of a scalar quantum field. In this paper, we extend that construction to more general theories which do not refer to any background, space-time metric (and in which the space of histories does not admit a natural linear structure). Examples include certain gauge theories, topological field theories and relativistic gravitational theories. The treatment is self-contained in the sense that an a priori knowledge of the Osterwalder-Schrader theorem is not assumed.

description: Halidon rings are rings with a unit element, containing a primitive $m^{th}$ root of unity and $m$ is invertible in the ring. The field of complex numbers is a halidon ring with any index $ m \geq 1$. In this article, the author examines the computational aspects of a new class of rings called Halidon rings and their applications with the help of computer codes. In representation theory, Maschke's theorem has an important role in studying the irreducible subrepresentations of a given group representation. Mainly the study is related to a finite field of characteristic which does not divide the order of the given finite group or the field of real or complex numbers. This article also examines the possibility of replacing the finite field in the theorem with halidon rings in such a way that the theorem is still valid. Halidon rings are rings with the unit element, containing a primitive $m^{th}$ root of unity and $m$ is invertible in the ring. The field of complex numbers is a halidon ring with any index $ m \geq 1$. Some computer codes have been developed to establish the existence of halidon rings which are not fields and the computation of units, involutions and idempotents in both halidon rings and halidon group rings. The application halidon rings in Discrete Fourier Transform (DFT) is studied and two computer codes have been developed to calculate DFT and inverse DFT

description: Selecting skilled mutual funds through the multiple testing framework has received increasing attention from finance researchers and statisticians. The intercept $α$ of Carhart four-factor model is commonly used to measure the true performance of mutual funds, and positive $α$'s are considered as skilled. We observe that the standardized OLS estimates of $α$'s across the funds possess strong dependence and nonnormality structures, indicating that the conventional multiple testing methods are inadequate for selecting the skilled funds. We start from a decision theoretic perspective, and propose an optimal testing procedure to minimize a combination of false discovery rate and false non-discovery rate. Our proposed testing procedure is constructed based on the probability of each fund not being skilled conditional on the information across all of the funds in our study. To model the distribution of the information used for the testing procedure, we consider a mixture model under dependence and propose a new method called "approximate empirical Bayes" to fit the parameters. Empirical studies show that our selected skilled funds have superior long-term and short-term performance, e.g., our selection strongly outperforms the S\&P 500 index during the same period.

description: In this deliverable the results of case study 3 " Strategic development of Pan-European network" are described. The general objective of plan4res is to fill the gaps between the increasing complexity of the future energy system planning and operational problems and the currently available system analysis tools. Enhanced end-to-end planning and operational tools dealing with technological and market uncertainty, emerging technologies and increased sector coupling of multi-energy vectors such as heat, cold and transport are assembled in a synergistic approach to support European system planners, operators, decision makers, regulators.
 The modular nature of the tools allows them to be tailored to the specifc needs of different nature entities and can adapt to the wished (or data imposed) granularity. This is highlighted by a set of exemplary case studies. Each of these case studies focuses on a different viewpoint on the energy system and the methods and tools necessary to solve their use cases, questions and challenges. Those case studies show the adequacy and relevance of the developed tools and modeling framework and its interoperability. The present case study is devoted to demonstrating that the Seasonal Storage Valuation and European unit Commitment Models are meeting the expectations. With this case study we show that:
 - The models are able to evaluate the feasibility of a given long-term energy mix scenario, and to assess the costs of thos scenario from the point of view of the energy system. In cas Study 3 we demonstrated this on the specific case of one of the recently published openENTRANCE scenarios.
 - With this models it is possible to run exibility assessment studies, in order to evaluate the value of a given kind of exibility. Within case study 3, we have shown examples of exibility evaluation related to storage, interconnections, and thermal generation - Finally we demonstrated that the models were able to capture the cost and value of hosting more Variable renewable Generation Systems in the electricity mix.
Role of intracluster supernovae in radio mini-halos in galaxy clusters

description: A possibility of generating a population of cosmic-ray particles accelerated in supernovae typeIa (SNIa) remnants in the intracluster medium (ICM) is discussed. The presently constrained host-less SNIa rates in the clusters are found to be sufficient to fill a few hundred kpc region with cosmic-ray electrons within their typical synchrotron life-time of 100 Myr. The SNIa have already been considered potential sources of excess Fe abundance in cool-core clusters, distributed heating and turbulence in ICM. A good fraction of total radio power from mini-halos can be sourced from the SNIa energy deposited in the ICM with required energy conversion efficiency <1 per cent. The radio power estimated from low Mach number shock acceleration in SNIa remnants is consistent with the observations within the uncertainties in the estimates. Some observational properties of the radio mini-halos are broadly consistent with the SNIa scenario. It is also speculated that radio powers and possibly detections of mini-halos are linked to star formation and merger histories of the clusters.

description: The catalytic potential of tris(hydroxymethyl)aminomethane (Tromethamine) has been assessed for the one pot three component tandem reaction involving a thiazolylmethoxy phenyl/aromatic carboxaldehyde, substituted amines and thioglycolic acid to form new thiazolyl-4-thiazolidinones and known substituted-4-thiazolidinones. This strategy involves the use of tromethamine as a reusable promoter and water as an eco-friendly reaction medium. The merits of this protocol are high atom economy, mild reaction conditions, good yields of desired products in short reaction times, and reusable reaction medium. The generality and functional tolerance of this convergent and environmentally benign method is demonstrated.
