description: Additive asynchronous and cyclostationary impulsive noise limits communication performance in OFDM powerline communication (PLC) systems. Conventional OFDM receivers assume additive white Gaussian noise and hence experience degradation in communication performance in impulsive noise. Alternate designs assume a parametric statistical model of impulsive noise and use the model parameters in mitigating impulsive noise. These receivers require overhead in training and parameter estimation, and degrade due to model and parameter mismatch, especially in highly dynamic environments. In this paper, we model impulsive noise as a sparse vector in the time domain without any other assumptions, and apply sparse Bayesian learning methods for estimation and mitigation without training. We propose three iterative algorithms with different complexity vs. performance trade-offs: (1) we utilize the noise projection onto null and pilot tones to estimate and subtract the noise impulses; (2) we add the information in the data tones to perform joint noise estimation and OFDM detection; (3) we embed our algorithm into a decision feedback structure to further enhance the performance of coded systems. When compared to conventional OFDM PLC receivers, the proposed receivers achieve SNR gains of up to 9 dB in coded and 10 dB in uncoded systems in the presence of impulsive noise.

description: Current research in iris recognition is moving towards enabling more relaxed acquisition conditions. This has effects on the quality of acquired images, with low resolution being a predominant issue. Here, we evaluate a super-resolution algorithm used to reconstruct iris images based on Eigen-transformation of local image patches. Each patch is reconstructed separately, allowing better quality of enhanced images by preserving local information. Contrast enhancement is used to improve the reconstruction quality, while matcher fusion has been adopted to improve iris recognition performance. We validate the system using a database of 1,872 near-infrared iris images. The presented approach is superior to bilinear or bicubic interpolation, especially at lower resolutions, and the fusion of the two systems pushes the EER to below 5% for down-sampling factors up to a image size of only 13x13.

description: We used the proximity effect as a tool to achieve an ideal (barrier - free) NS boundary for quantitative evaluation of transport phenomena that accompany converting dissipative current into supercurrent in NS systems with unconventional superconductors, single - crystal chalcogenide FeSe and granulated pnictide LaO(F)FeAs. Using features (limitations) of Andreev reflection in the NS systems with dispersion of the electron spin subbands, we revealed direct evidence for spin - polarized nature of transport and the absence of residual magnetization in iron - based superconductors in the normal state: In heterocontacts with single - crystal FeSe and granular LaO(F)FeAs, we detected a spin-dependent contribution to the efficiency of the Andreev reflection associated with the spin accumulation at the NS boundary, and a hysteresis of conductivity of FeSe in the ground state in low external magnetic fields. Based on our findings, we conclude that in iron-based superconductors, the itinerant electron magnetism is predominant, magnetism of iron atoms being localized.

description: This paper establishes the equivalence between systems described by a single first-order hyperbolic partial differential equation and systems described by integral delay equations. System-theoretic results are provided for both classes of systems (among them converse Lyapunov results). The proposed framework can allow the study of discontinuous solutions for nonlinear systems described by a single first-order hyperbolic partial differential equation under the effect of measurable inputs acting on the boundary and/or on the differential equation. An illustrative example shows that the conversion of a system described by a single first-order hyperbolic partial differential equation to an integral delay system can simplify considerably the solution of the corresponding robust feedback stabilization problem.

description: Barten's model of spatio-temporal contrast sensitivity function of human visual system is embedded in a multi-slice channelized Hotelling observer. This is done by 3D filtering of the stack of images with the spatio-temporal contrast sensitivity function and feeding the result (i.e., the perceived image stack) to the multi-slice channelized Hotelling observer. The proposed procedure of considering spatio-temporal contrast sensitivity function is generic in the sense that it can be used with observers other than multi-slice channelized Hotelling observer. Detection performance of the new observer in digital breast tomosynthesis is measured in a variety of browsing speeds, at two spatial sampling rates, using computer simulations. Our results show a peak in detection performance in mid browsing speeds. We compare our results to those of a human observer study reported earlier (I. Diaz et al. SPIE MI 2011). The effects of display luminance, contrast and spatial sampling rate, with and without considering foveal vision, are also studied. Reported simulations are conducted with real digital breast tomosynthesis image stacks, as well as stacks from an anthropomorphic software breast phantom (P. Bakic et al. Med Phys. 2011). Lesion cases are simulated by inserting single micro-calcifications or masses. Limitations of our methods and ways to improve them are discussed.

Prostate cancer and homologous recombination repair gene mutations: a monocentric observational study on clinical and histopathological features and their association with oncological outcomes
Creators: name: Rossetti, Sabrina
name: Coppola, Elisabetta
Publisher: name: Zenodo
Year: 2025

description: This study provides real-world evidence that homologous recombination repair (HRR) gene mutations, particularly in BRCA2, are associated with more aggressive clinical and pathological features in patients with metastatic hormone-sensitive prostate cancer (mHSPC). Importantly, mutations located in functional domains of BRCA2, such as the DNA-binding domain and exon 11, were linked to worse oncological outcomes. The findings suggest that not all BRCA2 mutations carry the same prognostic value. These results support the potential utility of detailed genetic profiling for risk stratification and treatment personalization in mHSPC.

description: We study spatial correlations in the transport of energy between two baths at different temperatures. To do this, we introduce a minimal model in which energy flows from one bath to another through two subsystems. We show that the transport-induced energy correlations between the two subsystems are of the same order as the energy fluctuations within each subsystem. The correlations can be either positive or negative and we give bounds on their values which are associated with a dynamic energy scale. The different signs originate as a competition between fluctuations generated near the baths, and fluctuations of the current between the two subsystems. This interpretation sheds light on known results for spatially-dependent heat and particle conduction models.

description: In this paper, we present a new approach for periocular recognition based on the Symmetry Assessment by Feature Expansion (SAFE) descriptor, which encodes the presence of various symmetric curve families around image key points. We use the sclera center as single key point for feature extraction, highlighting the object-like identity properties that concentrates to this unique point of the eye. As it is demonstrated, such discriminative properties can be encoded with a reduced set of symmetric curves. Experiments are done with a database of periocular images captured with a digital camera. We test our system against reference periocular features, achieving top performance with a considerably smaller feature vector (given by the use of a single key point). All the systems tested also show a nearly steady correlation between acquisition distance and performance, and they are also able to cope well when enrolment and test images are not captured at the same distance. Fusion experiments among the available systems are also provided.

Reduced-Rank DOA Estimation based on Joint Iterative Subspace Optimization and Grid Search

Publisher: name: arXiv
Year: 2013
Subjects: subject: Information Theory (cs.IT)

description: In this paper, we propose a novel reduced-rank algorithm for direction of arrival (DOA) estimation based on the minimum variance (MV) power spectral evaluation. It is suitable to DOA estimation with large arrays and can be applied to arbitrary array geometries. The proposed DOA estimation algorithm is formulated as a joint optimization of a subspace projection matrix and an auxiliary reduced-rank parameter vector with respect to the MV and grid search. A constrained least squares method is employed to solve this joint optimization problem for the output power over the grid. The proposed algorithm is described for problems of large number of users' direction finding with or without exact information of the number of sources, and does not require the singular value decomposition (SVD). The spatial smoothing (SS) technique is also employed in the proposed algorithm for dealing with correlated sources problem. Simulations are conducted with comparisons against existent algorithms to show the improved performance of the proposed algorithm in different scenarios.

description: Abstract This article reviews some results of the SAGEX programme that have developed in the understanding of the interplay of supersymmetry and modular covariance of scattering amplitudes in type IIB superstring theory and its holographic image in N = 4 supersymmetric Yang–Mills theory (SYM). The first section includes the determination of exact expressions for BPS interactions in the low-energy expansion of type IIB superstring amplitudes. The second section concerns properties of a certain class of integrated correlators in N = 4 SYM with arbitrary classical gauge group that are exactly determined by supersymmetric localisation. Not only do these reproduce known features of perturbative and non-perturbative N = 4 SYM for any classical gauge group, but they have large-N expansions that are in accord with expectations based on the holographic correspondence with superstring theory. The final section focusses on modular graph functions. These are modular functions that are closely associated with coefficients in the low-energy expansion of superstring perturbation theory and have recently received quite a lot of interest in both the physics and mathematics literature.

description: The Kepler Eclipsing Binary Catalog (KEBC)describes 2165 eclipsing binaries identified in the 115 deg^2 Kepler Field based on observations from Kepler quarters Q0, Q1, and Q2. The periods in the KEBC are given in units of days out to six decimal places but no period errors are provided. We present the PEC (Period Error Calculator) algorithm which can be used to estimate the period errors of strictly periodic variables observed by the Kepler Mission. The PEC algorithm is based on propagation of error theory and assumes that observation of every light curve peak/minimum in a long time-series observation can be unambiguously identified. The PEC algorithm can be efficiently programmed using just a few lines of C computer language code. The PEC algorithm was used to develop a simple model which provides period error estimates for eclipsing binaries in the KEBC with periods less than 62.5 days. KEBC systems with periods >=62.5 days have KEBC period errors of about 0.0144 days. Periods and period errors of 7 eclipsing binary systems in the KEBC were measured using the NASA Exoplanet Archive Periodogram Service and compared to period errors estimated using the PEC algorithm.

description: One of the major obstacles to realizing spintronic devices such as MESO logic devices is the small signal magnitude used for magnetization readout, making it important to find materials with high spin-to-charge conversion efficiency. Although intermixing at the junction of two materials is a widely occurring phenomenon, its influence on material characterization and the estimation of spin-to-charge conversion efficiencies is easily neglected or underestimated. Here, we demonstrate all electrical spin-to-charge conversion in Bi$_x$Se$_{1-x}$ nanodevices and show how the conversion efficiency can be overestimated by tens of times depending on the adjacent metal used as a contact. We attribute this to the intermixing-induced compositional change and the properties of a polycrystal that lead to drastic changes in resistivity and spin Hall angle. Strategies to improve the spin-to-charge conversion signal in similar structures for functional devices are discussed.

Minimal entropy approximation for cellular automata

Year: 2013
Subjects: subject: Cellular Automata and Lattice Gases (nlin.CG)

description: We present a method for construction of approximate orbits of measures under the action of cellular automata which is complementary to the local structure theory. The local structure theory is based on the idea of Bayesian extension, that is, construction of a probability measure consistent with given block probabilities and maximizing entropy. If instead of maximizing entropy one minimizes it, one can develop another method for construction of approximate orbits, at the heart of which is the iteration of finitely-dimensional maps, called minimal entropy maps. We present numerical evidence that minimal entropy approximation sometimes spectacularly outperforms the local structure theory in characterizing properties of cellular automata. Density response curve for elementary CA rule 26 is used to illustrate this claim.

description: This study aims to determine the mapping of research topics around the Kafalah contract in the Islamic Financial Inclusion using a mix-method approach, namely the VOSviewer bibliometric study and Library Research. Data analysis techniques include: (1) mapping the distribution of journal publications regarding the Kafalah contract; (2) mapping the results of the VOSviewer bibliometric visualization regarding the Kafalah contract based on the number of clusters and their items; and (3) mapping research topics around the Kafalah contract using a Library Research study. The results of the study show that: (1) based on the mapping of the distribution of journal publications, there are 32 journal publications regarding the Kafalah contract; (2) based on VOSviewer's bibliometric study mapping, the network visualization results around the Kafalah contract are divided into 7 clusters and 87 topic items; (3) based on the mapping of Library Research studies, there are 3 main topics surrounding the Kafalah contract. The difference between this research and previous research is that this study explains and maps all research topics around the Kafalah contract so that future researchers can find the research gaps around the Kafalah contract. The implication and contribution of this research is that there is a mapping of research topics around the Kafalah contract, which is often or rarely researched by researchers to be a reference for future researchers.

description: The combination of graphene with noble-metal nanostructures is currently being explored for strong light-graphene interaction enhanced by plasmons. We introduce a novel hybrid graphene-metal system for studying light-matter interactions with gold-void nanostructures exhibiting resonances in the visible range. Strong coupling of graphene layers to the plasmon modes of the nanovoid arrays results in significant frequency shifts of the underlying plasmon resonances, enabling more than 30% absolute light absorption in a single layer of graphene and up to 700-fold enhancement of the Raman response of the graphene. These new perspectives enable us to verify the presence of graphene on gold-void arrays and the enhancement even allows us to accurately quantify the number of layers. Experimental observations are further supported by numerical simulations and perturbation-theory analysis. The graphene gold-void platform is beneficial for sensing of molecules and placing R6G dye molecules on top of the graphene, we observe a strong enhancement of the R6G Raman fingerprints. These results pave the way toward advanced substrates for surface-enhanced Raman scattering (SERS) with potential for unambiguous single-molecule detection on the atomically well-defined layer of graphene.

D1.3 – Data Management Plan
Creators: name: Ghoraishi, Mir
name: Gutiérrez Terán, Jesús
name: Pryor, Simon
Publisher: name: Zenodo
Year: 2023

description: This document presents the data management guideline, according to the GDPR, for all activities related to BeGREEN project. As any other research and development project, BeGREEN produces data in different formats in the format of various types of documents and electronic files. Therefore, it is essential for the project and consortium to have clear guidelines on how to produce, handle, store, and share this data. To this end, the consortium has adhered to the H2020 ORDP (Open Research Data Pilot) convention with the EC, which explicitly caters for the delivery of a DMP (Data Management Plan).

This document, BeGREEN D1.3, describes both the set of principles to guide the data collection and preservation and the ongoing and future activities handling with data, before and even after the project is completed.

Detailed information included in the DMP are data management lifecycle for all data sets that will be collected, processed, or generated by the consortium during the project related research and developments. The procedures on how research data will be handled during the project, and even after the project is completed are outlined. These guidelines describe what data will be collected, processed, or generated and following what methodology and standards, whether and how this data will be shared and/or made open, and how it will be curated and preserved.

Three main data scenarios are envisaged:

•         Original data produced by the consortium and/or individual members of it (e.g., during the piloting activities, the case studies research and the dissemination activities);

•         Existing data already in possession of the consortium and/or individual members of it prior to the project’s initiation;

•         Existing data sourced/procured by the consortium and/or individual members of it during the project’s timeline.

Finally, it is reminded that the DMP presented in BeGREEN D1.2 is a living document and future releases, if needed, will be adapted to the needs and processes of the experiments and trials, taking in consideration the GDPR guidelines and the project evolution.
Galileon bounce after ekpyrotic contraction
Creators: name: Osipov, M.

Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider a simple cosmological model that includes a long ekpyrotic contraction stage and smooth bounce after it. Ekpyrotic behavior is due to a scalar field with a negative exponential potential, whereas the Galileon field produces bounce. We give an analytical picture of how the bounce occurs within the weak gravity regime, and then perform numerical analysis to extend our results to a non-perturbative regime.

description: When a drop laden with solid particles and suspended in a liquid passes through a narrow pore, its interface experiences strong shear and elongation, and the raft of particles may accumulate toward the back of the drop. Using well controlled formulations of Pickering drops driven at set pressure, we determine the two conditions for which solid particles are expelled from the oil-water interface after a Pickering drop passes a converging-diverging pore: (i) particles accumulation at the rear of the drop is such that surface pressure builds-up at the interface. (ii) Surface pressure relaxation by buckling is impaired by geometrical constraints. These two conditions are rationalized using three non dimensional numbers: the capillary number, the particle to pore size ratio, and the drop to particle size ratio, which allow to account for the viscous shear at the interface, the stability of the lubricating film between the pore wall and the drop, the drag on the raft of particles adsorbed at the interface, and its mechanical behaviour.
3D distribution of metals in nova shells
Creators: name: Schmidtobreick, Linda
Publisher: name: Zenodo
Year: 2023

description: A nova eruption in a cataclysmic variable (CV) is a thermonuclear explosion on the surface of the white dwarf primary once it has accreted a critical mass from its late-type companion. During the nova eruption, material is ejected into the interstellar medium, forming an expanding shell around the CV which can be observed once its angular size is sufficiently large to be resolved and separated from the inner binary. The spectra of such shells are usually dominated by various emission lines including Hydrogen, Helium and forbidden metal lines. We have used the Multi Unit Spectroscopic Explorer (MUSE) to observe several such nova shells. For any of the various emission lines present in the spectra, the radial velocity distribution at each spaxel relates directly to the spatial distribution in z-direction. Using Gaia distances, also the angular distribution can be transformed into physical x,y-coordinates. Thus, full 3D-images of the expanding shell can be constructed for the various emission lines. We find significant differences in the distribution of H or He and the forbidden metal lines. Such discriminating 3D-structures of the shells provide information on the mechanisms and processes during the nova eruption.

description: Due to the absence of a library for non-linear function evaluation, so-called general-purpose secure multi-party computation (MPC) are not as ''general'' as MPC programmers expect. Prior arts either naively reuse plaintext methods, resulting in suboptimal performance and even incorrect results, or handcraft ad hoc approximations for specific functions or platforms. We propose a general technique, NFGen, that utilizes pre-computed discrete piecewise polynomials to accurately approximate generic functions using fixed-point numbers. We implement it using a performance-prediction-based code generator to support different platforms. Conducting extensive evaluations of 23 non-linear functions against six MPC protocols on two platforms, we demonstrate significant performance, accuracy, and generality improvements over existing methods.

On the equilibrium figure of close-in planets and satellites

description: Many exoplanets have been observed close to their parent stars with orbital periods of a few days. As for the major satellites of the Jovian planets, the figure of these planets is expected to be strongly shaped by tidal forces. However, contrarily to Solar System satellites, exoplanets may present high values for the obliquity and eccentricity due to planetary perturbations, and may also be captured in spin-orbit resonances different from the synchronous one. Here we give a general formulation of the equilibrium figure of those bodies, that makes no particular assumption on the spin and/or orbital configurations. The gravity field coefficients computed here are well suited for describing the figure evolution of a body whose spin and orbit undergo substantial variations in time.

description: The extreme space weather conditions resulting from high energetic events likes solar flares and Coronal Mass Ejections (CMEs) demand for reliable space weather forecasting. The magnetic flux tubes while rising through the convection zone gets twisted by the turbulent plasma flows, energizing the system and resulting in flares. We investigate the relationship between the subsurface plasma flows associated with flaring active regions and their surface magnetic flux and current helicity. The near-surface horizontal velocities derived from the ring-diagram analysis of active region patches using Global Oscillation Network Group (GONG) Doppler velocity measurements are used to compute the fluid dynamics descriptors like vertical divergence, vorticity and kinetic helicity used in this work. The flaring active regions are observed to have large value of vertical vorticity and kinetic helicity. Also, the horizontal flow divergence, vorticity, flux, kinetic and current helicities are observed to be significantly correlated and evolve in phase with each other. We observe that the integrated values of the above flow and magnetic parameters observed one day prior to the flare are significantly correlated with the integrated flare intensity of the active region. Hence, we show that strong vorticity/kinetic helicities lead to larger active region twisting, presumably generating high-intensity flares.
