description: In most classification tasks there are observations that are ambiguous and therefore difficult to correctly label. Set-valued classifiers output sets of plausible labels rather than a single label, thereby giving a more appropriate and informative treatment to the labeling of ambiguous instances. We introduce a framework for multiclass set-valued classification, where the classifiers guarantee user-defined levels of coverage or confidence (the probability that the true label is contained in the set) while minimizing the ambiguity (the expected size of the output). We first derive oracle classifiers assuming the true distribution to be known. We show that the oracle classifiers are obtained from level sets of the functions that define the conditional probability of each class. Then we develop estimators with good asymptotic and finite sample properties. The proposed estimators build on existing single-label classifiers. The optimal classifier can sometimes output the empty set, but we provide two solutions to fix this issue that are suitable for various practical needs.

Wavelet Monte Carlo dynamics: a new algorithm for simulating the hydrodynamics of interacting Brownian particles

Year: 2016
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We develop a new algorithm for the Brownian dynamics of soft matter systems that evolves time by spatially correlated Monte Carlo moves. The algorithm uses vector wavelets as its basic moves and produces hydrodynamics in the low Reynolds number regime propagated according to the Oseen tensor. When small moves are removed the correlations closely approximate the Rotne-Prager tensor, itself widely used to correct for deficiencies in Oseen. We also include plane wave moves to provide the longest range correlations, which we detail for both infinite and periodic systems. The computational cost of the algorithm scales competitively with the number of particles simulated, $N$, scaling as $N\ln N$ in homogeneous systems and as $N$ in dilute systems. In comparisons to established lattice Boltzmann and Brownian dynamics algorithms the wavelet method was found to be only a factor of order 1 times more expensive than the cheaper lattice Boltzmann algorithm in marginally semi-dilute simulations, while it is significantly faster than both algorithms at large $N$ in dilute simulations. We also validate the algorithm by checking it reproduces the correct dynamics and equilibrium properties of simple single polymer systems, as well as verifying the effect of periodicity on the mobility tensor.

QSL Squasher: A Fast Quasi-Separatrix Layer Map Calculator

description: Quasi-Separatrix Layers (QSLs) are a useful proxy for the locations where current sheets can develop in the solar corona, and give valuable information about the connectivity in complicated magnetic field configurations. However, calculating QSL maps even for 2-dimensional slices through 3-dimensional models of coronal magnetic fields is a non-trivial task as it usually involves tracing out millions of magnetic field lines with immense precision. Thus, extending QSL calculations to three dimensions has rarely been done until now. In order to address this challenge, we present QSL Squasher -- a public, open-source code, which is optimized for calculating QSL maps in both two and three dimensions on GPUs. The code achieves large processing speeds for three reasons, each of which results in an order-of-magnitude speed-up. 1) The code is parallelized using OpenCL. 2) The precision requirements for the QSL calculation are drastically reduced by using perturbation theory. 3) A new boundary detection criterion between quasi-connectivity domains is used, which quickly identifies possible QSL locations which need to be finely sampled by the code. That boundary detection criterion relies on finding the locations of abrupt field-line length changes, which we do by introducing a new Field-line Length Edge (FLEDGE) map. We find FLEDGE maps useful on their own as a quick-and-dirty substitute for QSL maps. QSL Squasher allows constructing high-resolution 3D FLEDGE maps in a matter of minutes, which is two orders of magnitude faster than calculating the corresponding 3D QSL maps. We include a sample of calculations done using QSL Squasher to demonstrate its capabilities as a QSL calculator, as well as to compare QSL and FLEDGE maps.

description: The $μν$SSM solves the $μ$ problem of supersymmetric models and reproduces neutrino data, simply using couplings with right-handed neutrinos $ν$'s. Given that these couplings break explicitly $R$ parity, the gravitino is a natural candidate for decaying dark matter in the $μν$SSM. In this work we carry out a complete analysis of the detection of $μν$SSM gravitino dark matter through $γ$-ray observations. In addition to the two-body decay producing a sharp line, we include in the analysis the three-body decays producing a smooth spectral signature. We perform first a deep exploration of the low-energy parameter space of the $μν$SSM taking into account that neutrino data must be reproduced. Then, we compare the $γ$-ray fluxes predicted by the model with Fermi-LAT observations. In particular, with the 95$\%$ CL upper limits on the total diffuse extragalactic $γ$-ray background using 50 months of data, together with the upper limits on line emission from an updated analysis using 69.9 months of data. For standard values of bino and wino masses, gravitinos with masses larger than about 4 GeV, or lifetimes smaller than $10^{28}$ s, produce too large fluxes and are excluded as dark matter candidates. However, when limiting scenarios with large and close values of the gaugino masses are considered, the constraints turn out to be less stringent, excluding masses larger than 17 GeV and lifetimes smaller than $4\times 10^{25}$ s.

Αρχικά, γίνεται μία ευρύτερη έρευνα που περιλαμβάνει σημαντικές πληροφορίες για το Δοτσικό μέσα από βιώματα αλλά και αξιόπιστες πηγές. Μέσα από την έρευνα αυτή, συγκεντρώνονται τα απαραίτητα δεδομένα για τον τόπο, την ιστορία του αλλά και τη φύση που τον περιβάλει. Η βαθιά κατανόηση του χωριού μας οδηγεί στο πρακτικό κομμάτι της εργασίας, το οποίο είναι σε πρώτο μέρος, η προσέγγιση και δημιουργία λογότυπου και συμβόλων τόσο των τοποθεσιών του χάρτη όσο και του photo book. Η δημιουργία της ταυτότητας και της αισθητικής είναι απαραίτητη έτσι ώστε να καταφέρει να «χτιστεί» εν συνεχεία το επόμενο μέρος. Έτσι, δημιουργείται λοιπόν, ο χάρτης, ο οποίος παρουσιάζει το χωριό από τα βόρεια προς τα νότια με τα σημεία του ορίζοντα να το υποδεικνύουν. Το κύριο μέρος του, είναι οι 9 τοποθεσίες, όπου, όπως θα δούμε, επισημαίνονται με δικά τους λογότυπα και έχουν σχεδιαστεί προσεκτικά μέσω της θεωρητικής έρευνας. Οι τοποθεσίες αυτές είναι αριθμημένες και σε συνδυασμό με τις πληροφορίες που βρίσκονται στην άκρη του χάρτη δημιουργούν μία ολοκληρωμένη εικόνα της φύσης, των μνημείων και των κτισμάτων του χωριού. Στο επόμενο μέρος, υλοποιείται το photo book, το οποίο λειτουργεί ως συμπληρωματικό βιβλίο του χάρτη. Οι 9 τοποθεσίες αναγράφονται σε αυτό, παραθέτοντας παραπάνω πληροφορίες αλλά και φωτογραφικό υλικό από την προσωπική μου συλλογή. Στη συνέχεια δημιουργείται προωθητικό υλικό, το οποίο βασίζεται στην αισθητική τόσο του χάρτη όσο και του photo book αλλά και μία online εφαρμογή-app, η οποία έχει φωτογραφικό υλικό από τις τοποθεσίες του χωριού αλλά και τον χάρτη σε ψηφιακή μορφή. Το φωτογραφικό υλικό που χρησιμοποιείται σε όλο τον σχεδιασμό, προέρχεται από την προσωπική μου συλλογή, η οποία είναι πλούσια χάρη στα χρόνια που επισκέπτομαι το Δοτσικό. Η προσεκτική ανάγνωση του χάρτη και του βιβλίου, αναδεικνύει στους επισκέπτες ή σε όσους θα ήθελαν να επισκεφθούν το χωριό, την φυσική ομορφιά του, τα έθιμά του και τα σημαντικά του κτίσματα. Τους βοηθά να το βιώσουν σα να είναι οι ίδιοι ντόπιοι. Συμπερασματικά, μέσω αυτής της εργασίας, ένα μικρό χωριό των μόλις 6 μόνιμων κατοίκων, κερδίζει την αναγνωρισιμότητα που του αξίζει και το βοηθά να εξελιχθεί, αναδεικνύοντας τις αξίες και την ιστορία του.

description: Motivated by a common Mathematical Finance topic, we discuss the reciprocal of the exit time from a cone of planar Brownian motion which also corresponds to the exponential functional of an associated Brownian motion. We prove a conjecture by Vakeroudis and Yor (2012) concerning infinite divisibility properties of this random variable and we present a novel simple proof of De Blassie's result (1987-1988) about the asymptotic behaviour of the distribution of the Bessel clock appearing in the skew-product representation of planar Brownian motion, for t large. Similar issues for the exponential functional of a Levy process are also discussed. We finally use the findings obtained by the windings approach in order to get results for quantities associated to the pricing of Asian options.

description: By using the theoretical approaches describing well the available data on $t$-integrated coherent photoproduction of light and heavy vector mesons in Pb-Pb ultraperipheral collisions (UPCs) at the Large Hadron Collider (LHC) in Run 1, we calculate the momentum transfer distributions for this process for $ρ$ and $J/ψ$ vector mesons in the kinematics of Run 2 at the LHC. We demonstrate that nuclear shadowing not only suppresses the absolute value of the cross sections, but also shifts the momentum transfer distributions toward smaller values of the momentum transfer $|t|$. This result can be interpreted as a broadening in the impact parameter space of the effective nucleon density in nuclei by 14\% in the case of $ρ$ and the nuclear gluon distribution by $5-11$\% in the case of $J/ψ$.

description: Nanoencapsulation of antioxidant molecules on protein nanoparticles (NPs) could be an advanced approach for providing stable, better food nutraceuticals and anticancer drugs. The bioavailability and stability of catechin (CAT) and epicatechin (ECAT) were very poor. In the present study, the CAT and ECAT were loaded on bovine serum albumin (BSA) NPs following desolvation method. The transmission electron microscope (TEM) and atomic force microscope (AFM) recorded size of CAT-BSA NPs and ECAT-BSA NPs were 45 ± 5 nm and 48 ± 5 nm respectively. The encapsulation efficiency of CAT and ECAT on BSA NPs was found to be 60.5 and 54.5 % respectively. CAT-BSA NPs and ECAT-BSA NPs show slow and sustained in vitro release. The CAT-BSA NPs and ECAT-BSA NPs were stable in solution at various temperatures 37°C, 47°C and 57°C. DPPH assay revealed that CAT and ECAT maintained their functional activity even after encapsulation on BSA NPs. Furthermore, the efficacy of CAT-BSA NPs and ECAT-BSA NPs determined against A549 cell lines was found to be improved. CAT and ECAT aptly encapsulated in BSA NPs, showed satisfactory sustained release, maintained antioxidant potential and found improved efficacy. This has thus suggested their more effective use in food and nutraceuticals as well as in medical field.

description: We develop a strategy for bounding from above the height of rational points of modular curves with values in number fields, by functions which are polynomial in the curve's level. Our main technical tools come from effective Arakelov descriptions of modular curves and jacobians. We then fulfill this program in the following particular case: If $p$ is a not-too-small prime number, let $X_0 (p )$ be the classical modular curve of level $p$ over $\bf Q$. Assume Brumer's conjecture on the dimension of winding quotients of $J_0 (p)$. We prove that there is a function $b(p)=O(p^{5} \log p )$ (depending only on $p$) such that, for any quadratic number field $K$, the $j$-height of points in $X_0 (p ) (K)$ which are not lifts of elements of $X_0^+ (p) ({\bf Q} )$, is less or equal to $b(p)$.

COVID-19
European COVID-19 Data Platform
COVID-19 Data Portal

description: Rich and integrated biomolecular data are essential to support the world's scientific research into COVID-19. These data underlie our biological understanding (viral biology, the infection processes and patient response), our ability to identify and track COVID-19 (epidemiology and viral spread) and our capacity to intervene (through public health, therapeutic and vaccine approaches). An early priority of the European COVID-19 Data Platform has been to bring together relevant biomolecular data and the scholarly literature describing these data along with tools, standards and other resources to support operations upon the data. In this deliverable, we report on content-building activities within the Platform that serve, through the COVID-19 Data Portal, to make discoverable and accessible biomolecular data, literature and collections (tools, standards and related resources) relating to COVID-19 (https://www.covid19dataportal.org/). Our content building has resulted to date in over 420,000 biomolecular data records, almost 110,000 literature records and 57 linked collections covering tools, standards and other resources. Data continue to grow in number and diversity. This content has seen heavy exposure to users and two use cases around drug development and bioinformatics illustrate impact.Our work builds upon and demonstrates the important foundations that are provided by well-managed biomolecular data and shows the potential of these data rapidly to be deployed to support urgent scientific challenges.

Reconstructing open quantum system dynamics with limited control

Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The dynamics of an open quantum system can be fully described and tomographically reconstructed if the experimenter has complete control over the system of interest. Most real-world experiments do not fulfill this assumption, and the amount of control is restricted by the experimental set-up. That is, the set of performable manipulations of the system is limited. For instance, imagine a set-up where unitary operations are easy to make, but only one measurement at the end of the experiment is allowed. In this paper, we provide a general reconstruction scheme that yields operationally well-defined dynamics for any conceivable kind of experimental situation. If one additional operation can be performed, these `restricted' dynamics allow for the construction of witnesses for initial correlations and the presence of memory effects. We demonstrate the applicability of our framework for the the two important cases where the set of performable operations comprises only unitary operations or projective measurements, respectively, and show that it provides a powerful tool for the description of quantum control experiments.

Statistical and computational intelligence approach to analytic continuation in Quantum Monte Carlo

description: The term analytic continuation emerges in many branches of Mathematics, Physics, and, more generally, applied Science. Generally speaking, in many situations, given some amount of information that could arise from experimental or numerical measurements, one is interested in extending the domain of such information, to infer the values of some variables which are central for the study of a given problem. For example, focusing on Condensed Matter Physics, state-of-the-art methodologies to study strongly correlated quantum physical systems are able to yield accurate estimations of dynamical correlations in imaginary time. Those functions have to be extended to the whole complex plane, via analytic continuation, in order to infer real-time properties of those physical systems. In this Review, we will present the Genetic Inversion via Falsification of Theories method, which allowed us to compute dynamical properties of strongly interacting quantum many--body systems with very high accuracy. Even though the method arose in the realm of Condensed Matter Physics, it provides a very general framework to face analytic continuation problems that could emerge in several areas of applied Science. Here we provide a pedagogical review that elucidates the approach we have developed.

description: This article deals with the question: What enables organizations to manage knowledge transfer? We present principal-agent theory as a foundation to explain barriers of knowledge transfer. We show mechanisms which can solve the principal-agent problem by means of network, organizational, and motivational characteristics. Thereafter, we give some empirical evidence from a survey with medical doctors. The results show that network characteristics in form of direct channels for interaction, organizational characteristics, and intrinsic motivation can support knowledge transfer. These three factors are part of a ‘second level management’.

On the Spectral Efficiency Limits of an OAM-based Multiplexing Scheme
Creators: name: Cagliero, Andrea
name: Gaffoglio, Rossella
Publisher: name: arXiv
Year: 2016
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: As reported in several recent publications, a spatial multiplexing involving the transmission of orthogonal waves carrying Orbital Angular Momentum (OAM) is unable to provide spectral efficiency improvements with respect to the conventional techniques. In this work we emphasize how the limits of an OAM multiple transmission between antenna arrays can be derived from the Shannon capacity formula, taking as a reference the performance of a multiplexing method based on the higher-order channel modes. Our approach clearly indicates that the two techniques offer the same on-axis performance. Conversely, small misalignments in the arrays positions affect the OAM scheme, highlighting the greater robustness of a traditional multiplexing method in the context of radio communications.

description: El presente trabajo investigativo centra su interés en una posible trazabilidad para el diseño de una guía metodológica que posibilite el fortalecimiento de la integración de las TIC en los múltiples procesos pedagógicos de la Institución Educativa Manuela Beltrán y el Colegio María Reina Del Carmelo de la ciudad de Medellín, toda vez que, estas son fundamentales para lograr el desarrollo y apropiación de las competencias digitales en función de las prácticas de aula, las cuales deben estar orientadas y priorizadas no solo por los maestros que imparten la educación regular sino que deben estar enmarcadas y definidas metodológicamente dentro de los proyectos educativos institucionales desde sus diferentes áreas de gestión escolar. Y es en este sentido que, mediante una intervención de corte cualitativo se implementaron algunas fases de trabajo en las cuales se buscó identificar la apropiación de la integración TIC en las prácticas de aula, se pretendió caracterizar estas y se abrió la puerta a un dialogo enriquecedor que debeló los puntos de encuentro pero también las dificultades marcadas, se posibilitó el análisis de algunos de los procesos de integración tecnológica y lo más importante aún, la posibilidad de continuar una ruta que posiblemente permita proponer lineamientos pedagógicos concertados que propendan por el mejoramiento de este aspecto dentro de la gestión escolar y su Proyecto Educativo Institucional.

D2.3 Final version of iv4xr Framework
Creators: name: Iv4XR
Publisher: name: Zenodo
Year: 2022

description: Deliverable D2.3 is the final version of the iv4XR Framework. Since the Deliverable-type D2.3 is OTHER, this document is not D2.3 itself, but rather a document that gives an overview of the Framework and its main components, and summarizes work done by WP2 on the Framework during the last project year. The reader is also referred to Deliverable D2.4, which is a report describing the Framework and the Framework Core. Document structure In Section-1 we provide an overview of the main components/modules of the iv4xr Framework. WP2 itself focuses on the agent-based infrastructure of Framework --the so- called Framework Core component. For overview we mention other main components of the Framework but will refer to the Reports where they will be described in more detail. In Section-2 we will give an overview of improvement on the Framework that is done by WP2 during the final year of the project.
Sizable NSI from the $SU(2)_L$ scalar doublet-singlet mixing and the implications in DUNE

description: We propose a novel and simple mechanism where sizable effects of non-standard interactions (NSI) in neutrino propagation are induced from the mixing between an electrophilic second Higgs doublet and a charged singlet. The mixing arises from a dimensionful coupling of the scalar doublet and singlet to the standard model Higgs boson. In light of the small mass, the light mass eigenstate from the doublet-singlet mixing can generate much larger NSI than those induced by the heavy eigenstate. We show that a sizable NSI $\varepsilon_{eτ}$ ($\sim 0.3$) can be attained without being excluded by a variety of experimental constraints. Furthermore, we demonstrate that NSI can mimic effects of the Dirac CP phase in the neutrino mixing matrix but they can potentially be disentangled by future long-baseline neutrino experiments, such as the Deep Underground Neutrino Experiment (DUNE).

Ergodicity breaking and Localization of the Nicolai supersymmetric fermion lattice model

description: We investigate dynamics of the supersymmetric fermion lattice model defined by Hermann Nicolai. We provide its local fermionic constants of motion that exist infinitely many. These generate hidden local supersymmetries that the Nicolai model possesses in addition to its defining dynamical supersymmetry. The existence of such local constants directly implies the breaking ergodicity of the model in the sense of Mazur. At zero temperature, there are infinitely many degenerated classical ground states. We discuss these MBL-like properties. First, we show the delocalization scenario proposed by De Roeck-Huveneers can not naively apply to the Nicolai model at zero temperature despite its disorder-free translation-invariant quantum interaction. Second, we discuss the quantum integrability of the Nicolai model based on the proposal by Caux-Mossel.

Block-proximal methods with spatially adapted acceleration

Subjects: subject: Optimization and Control (math.OC)
subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We study and develop (stochastic) primal--dual block-coordinate descent methods for convex problems based on the method due to Chambolle and Pock. Our methods have known convergence rates for the iterates and the ergodic gap: $O(1/N^2)$ if each block is strongly convex, $O(1/N)$ if no convexity is present, and more generally a mixed rate $O(1/N^2)+O(1/N)$ for strongly convex blocks, if only some blocks are strongly convex. Additional novelties of our methods include blockwise-adapted step lengths and acceleration, as well as the ability to update both the primal and dual variables randomly in blocks under a very light compatibility condition. In other words, these variants of our methods are doubly-stochastic. We test the proposed methods on various image processing problems, where we employ pixelwise-adapted acceleration.
On Horizonless Temperature with an Accelerating Mirror

description: A new solution of a unitary moving mirror is found to produce finite energy and emit thermal radiation despite the absence of an acceleration horizon. In the limit that the mirror approaches the speed of light, the model corresponds to a black hole formed from the collapse of a null shell. For speeds less than light, the black hole correspondence, if it exists, is that of a remnant.
