The Quark-Antiquark Contribution to the Fully Exclusive BFKL Evolution at NLL Accuracy

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We calculate the quark-anti-quark contribution to the next-to-leading logarithmic corrections to the BFKL kernel, retaining the dependence on the momenta of the produced particles. This allows us to study the details of the NLL corrections. We demonstrate that the standard calculation of the NLL corrections to the scattering of two off-shell gluons includes contributions from energies far above that which is probed at LL. This explicitly violates energy and momentum conservation in the evolution and could be a source of the reported large NLL corrections. The presented calculation is a step towards combining energy and momentum conservation with full NLL accuracy in the evolution.

description: Evolution algebras are non-associative algebras that describe non-Mendelian hereditary processes and have connections with many other areas. In this paper we obtain necessary and sufficient conditions for a given algebra $A$ to be an evolution algebra. We prove that the problem is equivalent to the so-called $SDC$ $problem$, that is, the $simultaneous$ $diagonalisation$ $via$ $congruence$ of a given set of matrices. More precisely we show that an $n$-dimensional algebra $A$ is an evolution algebra if, and only if, a certain set of $n$ symmetric $n\times n$ matrices $\{M_{1}, \ldots, M_{n}\}$ describing the product of $A$ are $SDC$. We apply this characterisation to show that while certain classical genetic algebras (representing Mendelian and auto-tetraploid inheritance) are not themselves evolution algebras, arbitrarily small perturbations of these are evolution algebras. This is intriguing as evolution algebras model asexual reproduction unlike the classical ones.

description: In this study, we test the theoretically predicted mass-loss behaviour as a function of stellar effective temperature across the so-called `bi-stability' jump (BSJ). We gathered radio observations of 30 OB supergiants (O8-B3). We derived the radio mass-loss rates and wind efficiencies, and compared our results with Halpha mass-loss rates and predictions based on radiation-driven wind models. he wind efficiency shows the possible presence of a local maximum around an effective temperature of 21~000 K -- in qualitative agreement with predictions. We also find that the radio mass-loss rates show good agreement with empirical Halpha rates. However, the empirical mass-loss rates are larger than the predicted rates from radiation-driven wind theory for objects above the BSJ temperature, whilst they are smaller for the rest. A new wind momenta-luminosity relation for O8-B0 stars has been derived.

description: The Health Institute Carlos III (ISCIII) is the main Public Research Entity funding, managing and carrying out biomedical research in Spain. From its Bioinformatics Unit (BU-ISCIII), we give support to a great variety of research groups with different needs and expertise, and also external researchers from universities and public hospitals and their associated research centers. In order to provide a unified and user friendly platform to execute standard genomics analysis, use our in-house tools and access the join pool of computational resources of our centers, we are using Galaxy.

Due to the complexity of our existing high performance computational (HPC) and data storage infrastructure, some parts of the standard Galaxy functionality will have to be extensively customized and even some parts of Galaxy Core code will have to be modified.

The challenges we are facing include:
 Adapting Galaxy to be aware of the existing data and folder structures in our data centers, and being able to import it without duplicating files in disk or renaming them. Interaction with our existing pipeline scheme: Nextflow + Singularity. For future work, implement a way to visualize Nextflow pipelines inside Galaxy workflow visualization tool and import, export, create and modify them from there. Cooperation with our archived data system so samples can be easily searched, storaged and recovered when needed. Making Galaxy able to distinguish not only from admins and users, but also from internal (registered in LDAP) and external users, allocating different resource limits and queues for their jobs and data managing schemes. Integration of Galaxy job manager within our diverse cluster infrastructure resource manager, keeping effective tracking of the users who submitted every job so results can be easily accessed both from Galaxy interface and command line. Coordination with our existing LIMS to give easy access to sample history and metadata to our researchers, and elaborate a registry of samples for maintenance and potential future uses. As our data may be clinical, we have to ensure our system follows all data protection laws and ethical principles for its storage and use for research.
Once the basic tasks are achieved, we would like to open our infrastructure and tools to external researchers, and share our expertise to other smaller bioinformatics groups (like clinical bioinformatics units in hospitals) which face similar challenges and may lack the expertise or manpower to address them alone.

description: ELIXIR is an intergovernmental organization that brings together life science resources across Europe. These resources include databases, software tools, training materials, cloud storage, and supercomputers. One of the goals of ELIXIR is to coordinate these resources so that they form a single infrastructure. This infrastructure makes it easier for scientists to find and share data, exchange expertise, and agree on best practices. ELIXIR's activities are divided into the following five areas Data, Tools, Interoperability, Compute and Training known as “platforms”. The ELIXIR Tools Platform works to improve the discovery, quality and sustainability of software resources.Software Best Practices task of the Tools Platform aims to raise the quality and sustainability of research software by producing, adopting, promoting and measuring information standards and best practices applied to the software development life cycle. We have published four (4OSS) simple recommendations to encourage best practices in research software and the Top 10 metrics for life science software good practices.

The next step is to adopt, promote, and recognize these information standards and best practices, by developing comprehensive guidelines for software curation, and through workshops for training researchers and developers towards the adoption of software best practices and improvement of the usability of Tools Platform products. Additionally, a direct outcome of this task will be a software management plan template, connected to a concise description of the guidelines for open research software. Produce a white paper for the software development management plan for ELIXIR which can be consequently used to produce training material.

description: We study the decay widths of the narrow resonances $D_{sj}^*(2317)$ and $D_{sj}(2460)$ in the chiral quark model, together with the well-known $D^\ast$ and $D_s^*$ mesons. All the parameters in our calculation are taken from Godfrey and Isgur's quark model except the $π^0-η$ mixing angle which is fixed by the $D_s^*$ decay widths. The calculated electromagnetic decay widths agree with those from other groups and the experimental data available quite well. However, the pionic decay widths of $D_{sj}(2317)$ and $D_{sj}(2460)$ are too small to fit the experimental data. We suspect that the simple chiral quark pion axial-vector interaction Hamiltonian is not suitable for hadron strong decays of $D_{sj}(2317)$ and $D_{sj}(2460)$.
Mathematical models for biological pattern formation in two dimensions
Creators: name: Lyons, Michael J.
Publisher: name: University of British Columbia
Year: 2008

description: The general problem of pattern formation in biological development is described. One possible type of general solution, reaction-diffusion theory, is outlined, together with the difficulties involved in definite experimental confirmation or rejection of it. The methods for linear analysis of reaction-diffusion equations are presented. An approximate analytical technique for solving nonlinear reaction-diffusion equations close to the onset of the pattern-forming instability is discussed. The technique, known as the adiabatic approximation, is applied to the problem of stripe formation in two spatial dimensions. This analytical result demonstrates the existence of a class of pattern-forming models which preferentially select striped patterns. This class of models is defined by the requirement that the reaction terms contain only odd powers of the departures from the homogeneous steady state. The nonlinear properties of reaction-diffusion models in two spatial dimensions have been extensively studied numerically using finite-difference methods. These computations support the results of the analysis and extend their validity to a wider range of parameter values. Additional nonlinear effects, for example elimination of pattern defects, orientation of pattern using monotonic gradients, and the stripe/spot transition, have been investigated computationally. Two specific instances of biological stripe formation are considered: the expression of segmentation genes in the early embryogenesis of Drosophila melanogaster, and the development of ocular dominance domains in the primary visual cortex of some higher vertebrates. Mechanisms by which the segmentation patterns could arise by reaction diffusion are discussed. Existing models for ocular dominance, which take the form of integro-differential equations, are analyzed using the adiabatic approximation. A fundamental connection between a symmetry in the visual system and stripe selection is established.

description: In recent years, studies in different areas have used gamification to improve users' flow experience. However, due to the high variety of the conducted studies and the lack of secondary studies (e.g., systematic literature reviews) in this field, it is difficult to get the state-of-the-art of this research domain. To address this problem, we conducted a systematic literature review to identify i) which gamification design methods have been used in the studies about gamification and Flow Theory, ii) which gamification elements have been used in these studies, iii) which methods have been used to evaluate the users' flow experience in gamified settings, and iv) how gamification affects users' flow experience. The main results show that there is growing interest to this field, as the number of publications is increasing. The most significant interest is in the area of gamification in education. However, there is no unanimity regarding the preferred method of the study or the effects of gamification on users' experience. Our results highlight the importance of conducting new experimental studies investigating how gamification affects the users' flow experience in different gamified settings, applications and domains.

description: Οι Σποράδες παρέμειναν υπό βενετική κυριαρχία από το 1454 ως το 1540. Οι Βενετοί, που έστελναν στα νησιά δύο διοικητές, έναν για τη Σκιάθο και τη Σκόπελο και έναν για τη Σκύρο, δεν επέφεραν ουσιαστικές αλλαγές στα νησιά. Οι κάτοικοι ήταν στην πλειονότητά τους ορθόδοξοι με δικό τους επίσκοπο και ζούσαν κυρίως από τη γεωργία και την κτηνοτροφία. Στην καθημερινή τους ζωή προβλήματα τους δημιουργούσαν τόσο οι Βενετοί διοικητές με τις τάσεις αισχροκέρδειας όσο και οι πειρατές που δρούσαν στην περιοχή τους. Αλλά και οι ίδιοι εκδίδονταν στην πειρατεία για να επιβιώσουν, όπως προκύπτει από παράπονα της Πύλης προς τη Βενετία. Η τελευταία απαιτούσε από τις τοπικές αρχές την τιμωρία των υπευθύνων αλλά δεν ήταν και διαθετειμένη να πατάξει τελείως το λαθρεμπόριο, καθώς έτσι εξασφαλιζόταν ένα ανεκτό επίπεδο διαβίωσης και θα αποφεύγονταν ταραχές. Στο ερώτημα αν οι Βενετοί διέψευσαν με τη συμπεριφορά τους τις προσδοκίες των νησιών, η αναζήτηση είναι ίσως ως ένα σημείο, για τις Σποράδες του 15ου αιώνα το δίλημμα ήταν με ποιον "προστάτη-τύραννο" θα σώζονταν ή θα ζημιώνονταν λιγότερο
description: The Sporades have been under venetian domination from 1454 to 1540. The Venetians, who were sending to the islands two governors, one for Skaithos and Skopelos and one for Skyros didn't make big changes to the islands. Most of the inhabitants of the islands were orthodox, had their bishop and were occupied with agriculture and cattle-breeding. In their daily life they had problems because of their governors sordid gain and because of the pirates in their area. But even the islands were occupied with the piracy for their survived. After complaints of the Sublime Port, Venice demanded of the governors in the area the punishment of the responsibles. But Venice didn't wanted to stop the contraband completely because with that way wanted to be a tolerable level of living in the islands

description: Recent advances in the fabrication of microelectromechanical systems (MEMS) and their evolution into nanoelectromechanical systems (NEMS) have allowed researchers to measure extremely small forces, masses, and displacements. In particular, researchers have developed position transducers with resolution approaching the uncertainty limit set by quantum mechanics. The achievement of such resolution has implications not only for the detection of quantum behavior in mechanical systems, but also for a variety of other precision experiments including the bounding of deviations from Newtonian gravity at short distances and the measurement of single spins. Here we demonstrate the use of a quantum point contact (QPC) as a sensitive displacement detector capable of sensing the low-temperature thermal motion of a nearby micromechanical cantilever. Advantages of this approach include versatility due to its off-board design, compatibility with nanoscale oscillators, and, with further development, the potential to achieve quantum limited displacement detection.

description: An adjoint method to calculate the gradient of island width in stellarators is presented and applied to a set of magnetic field configurations. The underlying method of calculation of the island width is that of Cary & Hanson (1991) (with a minor modification), and requires that the residue of the island centre be small. Therefore, the gradient of the residue is calculated in addition. Both the island width and the gradient calculations are verified using an analytical magnetic field configuration introduced in Reiman & Greenside (1986). The method is also applied to the calculation of the shape gradient of the width of a magnetic island in an NCSX vacuum configuration with respect to positions on a coil. A gradient-based optimization is applied to a magnetic field configuration studied in Hanson & Cary (1984) to minimize stochasticity by adding perturbations to a pair of helical coils. Although only vacuum magnetic fields and an analytical magnetic field model are considered in this work, the adjoint calculation of the island width gradient could also be applied to a magnetohydrodynamic (MHD) equilibrium if the derivative of the magnetic field with respect to the equilibrium parameters was known. Using the island width gradient calculation presented here, more general gradient-based optimization methods can be applied to design stellarators with small magnetic islands. Moreoever, the sensitivity of the island size may itself be optimized to ensure that coil tolerances with respect to island size are kept as high as possible.

description: The nodal lines of random wave functions are investigated. We demonstrate numerically that they are well approximated by the so-called SLE_6 curves which describe the continuum limit of the percolation cluster boundaries. This result gives an additional support to the recent conjecture that the nodal domains of random (and chaotic) wave functions in the semi classical limit are adequately described by the critical percolation theory. It is also shown that using the dipolar variant of SLE reduces significantly finite size effects.

Computer simulations of critical phenomena in systems with long range interaction: A study of ising dipoles and self-organized criticality in earthquakes
Creators: name: Xu, Huangjian
Publisher: name: University of British Columbia
Year: 2008

description: This thesis discusses scaling and critical behavior of two different models. One model describes Ising dipoles, originates in condensed matter physics and depicts equilibrium critical phenomena. The other model, taken from the earth sciences, describes faulting instabilities and the resulting earthqnakes, and involves self-organized criticality — a nonequilibrium phenomenon. Both models are characterized by long range interactions, with a resulting sensitivity to boundary conditions. The ordering properties of Ising dipoles on lattices are studied in a mean field theory and by Monte Carlo simulations. The mean field theory is manifestly shape independent in zero external field. In the case of dipoles on a diluted lattice the mean field theory predicts a critical concentration above which the low temperature phase is ferroelectric (or anti-ferroelectric depending on the lattice structure). Extensive Monte Carlo simulation results are in agreement with those of mean field theory. We propose a finite size scaling form that includes logarithmic corrections for systems at the critical dimensionality. In the case of dipoles on a body centered tetragonal lattice we found that the finite scaling form significantly improved the data collapse over the scaling form with mean field exponents. With lattice parameters appropriate to the Ising ferromagnetic compound LiHoF4,we obtain a ferromagnetic transition temperature Tc= 1.51K in excellent agreement with experiment. This indicates that the material LiHoF4 is dominated by the dipole-dipole interaction; since in the simulations we only include dipole-dipole interactions. For dipoles on the simple cubic lattice, the ordered state is made up of anti-ferromagnetic rows. The critical exponents obtained by finite size scaling are ß~1/7,y ~ 8/7 and a ~4/7. These results are in good agreement with those of high temperature series expansions. A model of self—organized ruptures in an elastic medium is developed; and applied to earthquakes. In the model the local ruptures are represented by double couples to be consistent with elastic theory. The explicit form of this double couple source is derived. The system is driven by slowly increasing the shear stress. The model evolves towards a self-organized critical state in which the earthquake distribution follows the Gutenberg Richter law with an exponent in agreement with observational data. By modeling the local static fatigue for the rocks, we also obtained Omori’s law for the rate of aftershocks. The effects of annealing are investigated.

description: Cosmic-ray-induced sputtering is one of the important desorption mechanisms at work in astrophysical environments. The chemical evolution observed in high-density regions, from dense clouds to protoplanetary disks, and the release of species condensed on dust grains, is one key parameter to be taken into account in interpretations of both observations and models. This study is part of an ongoing systematic experimental determination of the parameters to consider in astrophysical cosmic ray sputtering. As was already done for water ice, we investigated the sputtering yield as a function of ice mantle thickness for the two next most abundant species of ice mantles, carbon monoxide and carbon dioxide, which were exposed to several ion beams to explore the dependence with deposited energy. These ice sputtering yields are constant for thick films. It decreases rapidly for thin ice films when reaching the impinging ion sputtering desorption depth. An ice mantle thickness dependence constraint can be implemented in the astrophysical modelling of the sputtering process, in particular close to the onset of ice mantle formation at low visual extinctions.

description: Im Kontext der Arbeitswissenschaft stellt die wahrgenommene Anstren-gung einen zentralen Faktor dar, da sie den Leistungsgrad in Relation zu der Anforderung beschreibt. In der subjektiven Beurteilung ist eine erhöhte Anstrengung ebenfalls ein Indikator für ein erhöhtes Beanspru-chungsempfinden, was wiederrum beschreibt, ob eine Tätigkeit akzepta-bel ist oder nicht. Die meisten praktischen Beurteilungsinstrumente beruhen auf subjektiven Messskalen. Diese sind kostengünstig, haben aber den Nachteil, dass die Beurteilung der Anstrengung enorm vom Zeitpunkt der Befragung, von Zeitdruck oder Kenntnissen über die Dauer der Aufgabe abhängig ist. Zudem gibt es interindividuell Unterschiede in der Art der Beurteilung. Diese Gründe motivieren objektive Beurteilun-gen der körperlichen Anstrengung. Die Zielsetzung dieser Ausarbeitung ist es, die Kombination verschiedener Gelenkbewegungen zu berücksich-tigen, um ein Bewegungsmuster zu finden, welches eine erhöhte An-strengung identifiziert. Theoretische Ansätze und neuere Untersuchungen lassen den Rückschluss zu, dass sich im speziellen der Ruck zur Identifi-kation von Anstrengungserscheinungen eignet. Die vorliegende Ausarbei-tung setzt u. a. an diesen Forschungsergebnissen an und untersucht, welchen Einfluss der Ruck einer Bewegung auf die wahrgenommene Anstrengung hat. Hierzu werden drei Probandenstudien durchgeführt. In Experiment I wird untersucht, welche ruckbasierten Parameter Probanden mit erhöhter Anstrengung/Ermüdung von Probanden mit niedriger An-strengung/Ermüdung differenzieren. In dem Experiment II wird ein Musterabgleich der Ausprägung der ruckbasierten Paramater vorgenom-men, um den Zeitpunkt erhöhter Anstrengung (ZEA) zu identifizieren. Die dritte Untersuchung stellt eine Übertragung des ZEA-Verfahrens auf eine anwendungsnahe Tätigkeit dar. Das Ergebnis ist, dass die Frequenz und Amplituden der Peaks des Rucks aufgabenunabhängig den ZEA voraussagen. Zur Identifikation ist die Betrachtung des am meisten kontrollierten Gelenkes nötig. In diesem zeigt sich der ZEA durch kleine-re zeitliche Abstände der Peaks, größere Amplituden der Peaks und eine Erhöhung der Gesamtwinkelbewegung.
Part I : a simple model of the hypertriton. Part II : muon capture by 3He
Creators: name: Congleton, J.G.
Publisher: name: University of British Columbia
Year: 2008

description: The thesis is in two parts. Part I is covered in chapters 1 and 2 and concerns a simple model of the hypertriton developed by the author. The model is based on the fact that the lambda particle is loosely bound and so a lambda-inert core approach should be reasonable. The core is taken to be exactly like the free deuteron and a separable AN potential is used to construct the binding potential for the A particle. The model is tested in chapter 2 by calculating the ratio of two body to all pionic decay rates of the hypertriton and the result is found to agree well with experiment. Chapters 3 to 7 concern muon capture by 3He. Using the elementary particle model it is shown that the spin observables for quasi-elastic muon capture by 3He are much more sensitive to the nuclear pseudoscalar form factor ( and hence the nucleon pseudoscalar form factor ) than is the rate. Reliable and sophisticated wavefunctions for 3He and are then used to find the muon capture Hamiltonian in the impulse approximation. The result differs from that found in the elementary particle model in that the magnetic ( and dominant ) part of the Hamiltonian lacks strength. In chapter 5 new theory is developed for the muon wavefunction overlap reduction factor leading to the result C = 0.979. Chapter 6 details a calculation of muon capture by 3He leading to the deuteron neutron break-up final state in the plane wave impulse approximation. Finally, the processes leading to muonic atom formation are considered in chapter 7 with particular reference to final hyperfine population densities and their dependencies on target and beam polarization. It is shown that if only the intra-atomic processes are included, the results for the hyperfine population densities are unreliable.

description: The simple structure of doubly torqued vectors allows for a natural characterization of doubly twisted down to warped spacetimes, as well as Kundt spacetimes down to PP waves. For the first ones the vectors are timelike, for the others they are null. We also discuss some properties, and their connection to hypersurface orthogonal conformal Killing vectors, and null Killing vectors.

description: Τα οικοσυστήματα είναι σύνθετες ενότητες στις οποίες συμμετέχουν πολλά είδη σε διάφορα χωρικά επίπεδα. Ο στόχος αυτής της εργασίας ήταν η μελέτη της επίδρασης των περιβαλλοντικών παραμέτρων στην επιλογή βιότοπου αναπαραγωγής ημερόβιων αρπακτικών πουλιών που συνυπάρχουν στο εθνικό πάρκο Δαδιάς. Οι παράγοντες του περιβάλλοντος αναλύθηκαν με χρήση γεωγραφικών συστημάτων πληροφόρησης. Η επιλογή του βιότοπου έγινε με δύο προσεγγίσεις: α) Με ανάλυση της επιλογής σε ακτίνα 17,85 Μ (0,1 ΗΑ) γύρω από το δέντρο φωλιάς και β) σε μεταβλητή χωρική κλίμακα με χρήση οικολογικών μοντέλων και Γ.Σ.Π. σύμφωνα με τα αποτελέσματα οι θέσεις φωλιάσματος διαφοροποιήθηκαν με βάση το υψόμετρο. Η ανθρώπινη δραστηριότητα δεν επιδρούσε αρνητικά στην παρουσία των ειδών. Η γεωμορφολογία και η γειτνίαση στους χώρους διατροφής αποτελούν τους αρχικούς παράγοντες διαφοροποίησης των ειδών. Στη συνέχεια η κατανομή είναι αποτέλεσμα του ενδοειδικού και διαειδικού ανταγωνισμού. Μέσα στην επιλεγόμενη περιοχή τα αρπακτικά πουλιά είναι επιλεκτικά στα χαρακτηριστικά της δομής του δάσους και των δέντρων φωλιάσματος. Η πρόβλεψη περιοχών αναπαραγωγής με τη βοήθεια οικολογικών μοντέλων θα βοηθήσει τους διαχειριστές στον καλύτερο σχεδιασμό της διαχείρισης των οικοσυστημάτων.
description: The ecosystems are complicated units including many species in different spatial levels. The aim of this study was the study of the effects of environmental factors on the nesting habitat selection of diurnal birds of prey coexisting in the Dadia national park the environmental factors were analysed using geographical information systems. Habitat selection was investigated in two ways: a) through the analysis of the habitat of 17,85M (0,1 HA) around the nest tree and b) in a multiscale level using ecological models and GIS. The results indicated that the nest sites were differentiated by altitude. The human activities did not negatively affect the presence of raptors. Geomorphology and neighbouring to foragine areas were the primare factors differentiative the species. Then, the distribution of pairs was the results of inter- and intraspecific competition. In their wider area the species were selective to the caracteristics of the forest structure and nest-trees.

description: It is shown that fine-tuning of the Higgs parameters stronger than a few % is required at the best in the models with gauge mediated supersymmetry breaking. With the aim of solving this problem, we consider a new type of models in which the top Yukawa coupling is induced at TeV scale through mass mixing with unknown matter fields. Then it is found that the fine-tuning problem can be eliminated essentially. We discuss some phenomenological features of this model and also consider the extension to the next-to-minimal models.

A wordless picturebook in pre-primary foreign language education: Mediating deep discussions
Creators: name: Mourão, Sandie
Publisher: name: Zenodo
Year: 2019
Subjects: English as a foreign language, response, wordless picturebook, values education

description: Objectives for foreign language education in contexts of low language exposure tend to focus on the learning of discrete language items, ignoring the broader benefits which can include the development of a respect for others. Generally, picturebooks are selected for the words they contain and, too often, little relevance is given to the images, thus the sharing of wordless picturebooks is unusual in this particular context. Wordless picturebooks might also demand an elaborate verbalization and so, for learners with very low English proficiency, recourse to their L1 may be required. The empirical study presented here is being undertaken with a group of pre-primary children (4 to 5 years old) learning English in a low-exposure context in Portugal. With a view to fostering a positive attitude towards peers with different skin colours, a wordless picturebook, Colour of People by Mauricio Negro, was incorporated into a sequence of storytelling sessions in English. The objective was to discover whether the children were able to demonstrate an understanding of the concept of prejudice through interaction with this wordless picturebook. Data was collected from audio recordings of shared picturebook readlouds, the children’s drawings and a researcher diary. Results suggest that discussion around such topics requires extensive recourse to the L1 but that input in the L2 can contribute to children’s acceptance of difference in themselves and others. They also suggest that picturebooks with words and images may be a more suitable tool to facilitate this acceptance. Implications for classroom practices will suggest approaches to mediation and developmentally appropriate book sets.

description: Προτείνεται ένα πλαίσιο λειτουργίας και μια μεθοδολογία για την εκτίμηση παραμέτρων μη γραμμικών συστημάτων. Δίνονται οι προϋποθέσεις για την αναγνωσιμότητα του υπό εξέταση συστήματος που εγγυάται την επιτυχία της μεθόδου εκτίμησης. Η μέθοδος εκτίμησης βασίζεται στην αξιολόγηση ενός συνόλου πιθανών διανυσμάτων παραμέτρων και την ανανέωση αυτού του συνόλου βάσει των αποτελεσμάτων αξιολόγησης.Η αξιολόγηση των μοντέλων γίνεται με τη χρήση συστημάτων PREMODES ενώ η ανανέωση του συνόλου των μοντέλων γίνεται με γενετικό αλγόριθμο. Η σύνδεση αυτών των διαδικασιών γίνεται μέσω του κριτηρίου εντροπίας. Ενας μεγάλος αριθμός πειραμάτων πάνω σε φυσικά συστήματα έδειξε ότι η προτεινόμενη μέθοδος παρουσιάζει καλύτερα αποτελέσματα από κλασσικές μεθόδους καθώς και καλύτερη συμπεριφορά σε ενθόρυβα δεδομένα εισόδου
description: A parameter estimation framework is suggested for nonlinear systems. The precoditions that the system has to fulfill in order to be identifiable are provided. The estimation method based on the credit of the probability in a set. The systems of estimation and decision PREMODES assign the credit in each model and the new generation of the models is produced by a Genetic Algorithm. The connection between the modules of probability assignment and of the new generation of models production is made with Entropy Criterion. A large number of experiments shows that the results are better than classic approaches even in case of noisy input data

description: We describe a complete, flux-density-limited sample of galaxies at redshift $0.8 < z < 1.3$ selected at 16 micron. At the selection wavelength near 8 micron rest, the observed emission comes both from dust heated by intense star formation and from active galactic nuclei (AGNs). Fitting the spectral energy distributions (SEDs) of the sample galaxies to local-galaxy templates reveals that more than half the galaxies have SEDs dominated by star formation. About one sixth of the galaxy SEDs are dominated by an AGN, and nearly all the rest of the SEDs are composite. Comparison with X-ray and far-infrared observations shows that combinations of luminosities at rest-frame 4.5 and 8 micron give good measures of both AGN luminosity and star-formation rate. The sample galaxies mostly follow the established star-forming main sequence for $z=1$ galaxies, but of the galaxies more than 0.5 dex above that main sequence, more than half have AGN-type SEDs. Similarly, the most luminous AGNs tend to have higher star-formation rates than the main sequence value. Galaxies with stellar masses $>$10$^{11}$\,\Msun\ are unlikely to host an AGN. About 1% of the sample galaxies show an SED with dust emission typical of neither star formation nor an AGN.

description: We give a representation of the parity-even part of the planar two-loop six-gluon MHV amplitude of N=4 super-Yang-Mills theory, in terms of loop-momentum integrals with simple dual conformal properties. We evaluate the integrals numerically in order to test directly the ABDK/BDS all-loop ansatz for planar MHV amplitudes. We find that the ansatz requires an additive remainder function, in accord with previous indications from strong-coupling and Regge limits. The planar six-gluon amplitude can also be compared with the hexagonal Wilson loop computed by Drummond, Henn, Korchemsky and Sokatchev in arXiv:0803.1466 [hep-th]. After accounting for differing singularities and other constants independent of the kinematics, we find that the Wilson loop and MHV-amplitude remainders are identical, to within our numerical precision. This result provides non-trivial confirmation of a proposed n-point equivalence between Wilson loops and planar MHV amplitudes, and suggests that an additional mechanism besides dual conformal symmetry fixes their form at six points and beyond.

description: This guideline sets out the process for the selection of individuals to participate in the Multi-Actor Platforms associated with the UNISECO project. An EU-level and 15 case study scale Multi-Actor Platforms will be brought together for the duration of the project. Multi-actor engagement will be used to ensure the consistent application of transdisciplinary methods. This approach, embedded in the composition of the consortium partners, seeks to strengthen the capacity of the project partners, the stakeholders and end users to assess the sustainability of different agro-ecological approaches and to prioritise policy interventions. A key aim of the use of the MAPs is to operate without gaps between science and practice, and to provide an advisory framework that will support a “systems
 approach”.
 An aim of this document is to ensure that partners will follow agreed steps in selecting and inviting appropriate stakeholders to participate in the platforms. It includes a range of actors at EU level (such as EU wide environmental NGO’s, sector organisations, policy makers and European Commission) and case study level (such as farmers, farm advisors and local and national authorities).
 This Guideline sets out the:
 i) purpose, aims and objectives of MAPs
 ii) criteria for identifying actors
 iii) procedure for selecting EU-Level MAP and Case Study MAP
 iv) procedure to explain and inform MAP’s participants
 v) management of MAP participation.
 This provides a coherent and streamlined approach to the selection of members of the Multi-Actor Platforms in the UNISECO project. The purpose of the approach is to ensure that the UNISECO project addresses directly, and is relevant to, the real needs on the ground, and to ensure that people with different types of knowledge are included throughout the project’s lifetime and beyond.
