description: The production of charged pions in minimum bias p+C interactions is studied using a sample of 377000 inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The data cover a phase space area ranging from 0 to 1.8 GeV/c in transverse momentum and from -0.1 to 0.5 in Feynman x. Inclusive invariant cross sections are given on a grid of 270 bins per charge thus offering for the first time a dense coverage of the projectile hemisphere and of the cross-over region into the target fragmentation zone.

description: We analyze the volume-limited nearly complete 100 pc sample of 95 halo white dwarf candidates identified by the second data release of Gaia. Based on a detailed population synthesis model, we apply a method that relies on Gaia astrometry and photometry to accurately derive the individual white dwarf parameters (mass, radius, effective temperature, bolometric luminosity and age). This method is tested with 25 white dwarfs of our sample for which we took optical spectra and performed spectroscopic analysis. We build and analyse the halo white dwarf luminosity function, for which we find for the first time possible evidences of the cut-off at its faintest end, leading to an age estimate of $\simeq12\pm0.5 $Gyr. The mass distribution of the sample peaks at $0.589\,M_{\odot}$, with $71\%$ of the white dwarf masses below $0.6\,M_{\odot}$ and just two massive white dwarfs of more than $0.8\,M_{\odot}$. From the age distribution we find three white dwarfs with total ages above 12 Gyr, of which J1312-4728 is the oldest white dwarf known with an age of $12.41\pm0.22 $Gyr. We prove that the star formation history is mainly characterised by a burst of star formation that occurred from 10 to 12 Gyr in the past, but extended up to 8 Gyr. We also find that the peak of the star formation history is centered at around 11 Gyr, which is compatible with the current age of the Gaia-Enceladus encounter. Finally, $13\%$ of our halo sample is contaminated by high-speed young objects (total age<7 Gyr). The origin of these white dwarfs is unclear but their age distribution may be compatible with the encounter with the Sagittarius galaxy.

description: We study exclusive nonleptonic and semileptonic decays of the Bc-meson within a relativistic constituent quark model previously developed by us. For the nonleptonic decays we use the factorizing approximation. We update our model parameters by using new experimental data for the mass and the lifetime of the Bc meson and the leptonic decay constants of the D-meson. We calculate the branching ratios for a large set of exclusive nonleptonic and semileptonic decays of the $B_c$ meson and compare our results with the results of other studies. As a guide for further experimental exploration we provide explicit formulas for the full angular decay distributions in the cascade decays Bc^- => J/psi(=> l^+l^-) + rho^-(=> pi^- pi^0) and Bc^- => J/psi(=> l^+l^-) + W^-(off-shell)(=> l^- + nubar).

description: We report the discovery of a compact triply eclipsing triple star system in the southern continuous viewing zone of the TESS space telescope. TIC 278825952 is a previously unstudied, circular eclipsing binary with a period of 4.781 days with a tertiary component in a wider, circular orbit of 235.55 days period that was found from three sets of third-body eclipses and from light travel-time effect dominated eclipse timing variations. We performed a joint photodynamical analysis of the eclipse timing variation curves, photometric data, and the spectral energy distribution, coupled with the use of PARSEC stellar isochrones. We find that the inner binary consists of slightly evolved, near twin stars of masses of 1.12 and 1.09 $M_\odot$ and radii of 1.40 and 1.31 $R_\odot$. The third, less massive star has a mass of 0.75 $M_\odot$ and radius of 0.70 $R_\odot$. The low mutual inclination and eccentricities of the orbits show that the system is highly coplanar and surprisingly circular.

description: Motivated by the recent lattice data that $J/ψ$ will survive up to 1.6$T_c$, we calculate the thermal width of $J/ψ$ at finite temperature in perturbative QCD. The inputs of the calculation are the parton quarkonium dissociation cross sections at the NLO in QCD, which were previously obtained by Song and Lee, and a gaussian charmonium wave function, whose size were fitted to an estimate by Wong by solving the schrodinger equation for charmonium in a potential extracted from the lattice at finite temperature. We find that the total thermal width above 1.4$T_c$ becomes larger than 100 to 200 MeV, depending on the effective thermal masses of the quark and gluon, which we take it to vary from 600 to 400 MeV.

description: No abstracts are to be cited without prior reference to the author. With changing climates, species distributions are shifting as organisms seek more suitable conditions. However, our ability to use this knowledge to guide fisheries adaptation is hindered in part by limited understanding for variation among species in their rate of shift. We tested hindcast projections against four decades of scientific surveys for 360 marine taxa on the continental shelves of North America. We found that much of the variation in species shifts in both latitude and depth could be explained by the rate and direction of local climate velocity. We also found evidence that fishing affected range shifts and that slow-growing taxa lagged behind their thermal niches more than other taxa. Our results suggest that species shift at different rates, and even in different directions, because they are tracking the complex mosaic of local climate velocities. These findings imply that projections of species distributions based on downscaled IPCC-class climate models will be useful tools for evaluating existing conservation plans and for guiding a new generation of climate-ready fisheries management.

description: We study quantum radiation emitted during the collapse of a quantized, gravitating, spherical domain wall. The amount of radiation emitted during collapse now depends on the wavefunction of the collapsing wall and the background spacetime. If the wavefunction is initially in the form of a sharp wavepacket, the expectation value of the particle occupation number is determined as a function of time and frequency. The results are in good agreement with our earlier semiclassical analysis and show that the quantum radiation is non-thermal and evaporation accompanies gravitational collapse.

We simulate Planck data for a range of assumed cosmological parameter values, and carry out a three-way Bayesian model comparison of a Harrison-Zel'dovich model, a power-law model, and a model including running. We find that Planck will be able to strongly support running only if its true value satisfies |dn/d ln k| > 0.02.

description: No abstracts are to be cited without prior reference to the author. Long-term observations over the period starting from the middle of the last century detected large scale fluctuations in population size of Atlanto-Scandian (Norwegian spring-spawning) herring (Clupea harengus Linne, 1758), changes in the structure of the population, its distribution and migration. After the collapse of the 70’s of the last century, the restoration started at the end of the century, and in recent years the decrease started again. Feeding migrations of herring were longer and distribution was wider in the years with high abundance and diverse age pattern of population against the background of positive temperature anomalies of water in NEA.

description: No abstracts are to be cited without prior reference to the author. The Barents Sea, located on the border of the boreal and arctic zones, is one of the most productive fishery areas of the Arctic shelf. Benthos is an important component of the ecosystem of this relatively shallow sea. Knipovich Polar Research Institute (PINRO) has a nearly century-old history of the study of benthos in the Barents Sea, the latest of quantitative survey was carried out in 2003-2006. The analysis of the benthos biomass from the Russian part of the Barents Sea showed a considerable effect of climate on benthos biomass. During the cold period in the early 20th century, the average biomass of benthos in the eastern part of the Barents Sea was 149 g  m-2 . In the followed warm period (1930-1962) it increased to 230 g  m-2 . In the second cold period (1963-1988) the biomass of benthos reduced to 68 g  m-2 . The current period is the warmest during the whole interval of investigations in the Barents Sea. The average biomass of macrozoobenthos in 2003-2006 was 335 g  m-2 . The result of analysis showed that in the eastern part of the Barents Sea, where the influence of the fishery is low, the average biomass of macrozoobenthos was two- five times higher in the warm periods compare to the periods of cooling.

Μέσα στο πλαίσιο αυτό παρουσιάζονται ο τελετουργικός χαρακτήρας των δημόσιων εκτελέσεων, η χρησιμοποίηση τους από το επίσημο κράτος αλλά και το πως η ελληνική κοινωνία αντιμετώπισε διαχρονικά το γεγονός. Για αυτό το λόγο οι έννοιες της τιμωρίας και του παραδειγματισμού αποτελούν τον βασικό άξονα προσέγγισης του θέματος. Μέσα από αυτό το πρίσμα εξετάζονται οι δημόσιες εκτελέσεις που πραγματοποιήθηκαν από την εποχή του Καποδίστρια και του Όθωνα μέχρι την περίοδο του Μεσοπολέμου και του Εμφυλίου, εστιάζοντας κυρίως στους στόχους που εξυπηρετούσαν σε κάθε εποχή. Παράλληλα παρουσιάζεται το νομικό πλαίσιο που καθόρισε την επιβολή της θανατικής εκτέλεσης στην Ελλάδα καθώς και οι αλλαγές που σημειώθηκαν προϊόντος του χρόνου.
description: The main object of the present thesis is the course and evolution of death penalties in Greece since the establishment of the modern Greek state until the mid 20th century. Within this framework, the ceremonial nature of public executions, their use by the official state and the way the Greek society has encountered the fact over the years, are presented. For this reason, the concepts of punishment and exemplary form the backbone approach of this issue. Within this perspective, the essay examines the public executions carried out from the Kapodistrias and Othonas’ administration up to the period of Interwar and Civil War, mainly focusing on the goals that served in every time period. In the meantime, the dissertation presents the legal framework which determined the imposition of the death penalty in Greece and changes that occurred within time.
EDGELESS D4.2: Refined platform services
Creators: name: Cicconetti, Claudio
Publisher: name: Zenodo
Year: 2024

description: This document provides a detailed description of the status of the EDGELESS services developed in the first 18 months of the project. First, we address the key topic of orchestration, i.e., the management of the active workflows on the available computing resources. Consistently with the two-layer architecture of EDGELESS illustrated in the companion deliverable D2.2, we distinguish between local vs. cluster orchestration. Regarding the former, i.e., local orchestration, we illustrate the reference implementation of a baseline orchestrator (ε-ORC), which realizes the key interactions with the other layers: ε-CON at a cluster level and nodes within its orchestration domain. Such baseline orchestration can be complemented by sophisticated orchestration policies running externally and following a so-called delegated orchestrator model, which is studied in the context of AI-based policies and anomaly detection. On the other hand, the design of cluster orchestration is analyzed, including cluster-level monitoring components and tools. We then describe solutions for edge-cloud-IoT integration, including cloud-based offloading solutions, data distribution agents, mainly intended for industrial scenarios, and the optimization of edge-cloud deployments. Furthermore, we describe the general approach of the project to continuous integration and continuous delivery, with a focus on two tools that are particularly relevant: the function repository, which provides the developers with a front-end for interacting with a database of function artifacts and metadata; and a benchmarking framework, to evaluate the performance of the system in repeatable and controlled conditions. Finally, we discuss how the WP4 activities in this period support the overall EDGELESS objectives and the status of the coverage of the key requirements. The reference implementation is available on a public GitHub repository and released under a permissive MIT license.

Ασχοληθήκαμε επιπλέον με τον ελληνορωμαϊκό οίκο και διαπιστώσαμε ότι αποτελούσε έναν πιο ανοικτό χώρο προς τη δημόσια σφαίρα, από αυτόν του «οίκου» της Παλαιστίνης, χωρίς να χάνει βέβαια την πατριαρχική του δομή και χαρακτήρα. Ακόμη, αναφερθήκαμε αναλυτικά στους οικιακούς Κώδικες στην αρχαιότητα και στην Καινή Διαθήκη και θίξαμε τη σχέση κειμένων από τη σφαίρα της ελληνιστικής φιλοσοφίας των στωικών ως πρός τον οικιακό κώδικα στην προς Κολοσσαείς επιστολή. Επίσης, παρουσιάσαμε αναλυτικά τη σχέση οίκου και λατρείας και εξετάσαμε το πολιτιστικό και κοινωνικό υπόβαθρο της εποχής εκείνης.

description: The purpose of this study is to present the deterministic and interpretive approach of «Haustafeln» in the New Testament and Greco-Roman environment. We studied the origin and purpose of the New Testament «Haustafeln» to understand the actual content of the codes and their role in the epistles. We also dealt with the Greco-Roman house and found that it constituted a more open space in the public sphere than the "house" of Palestine while preserving the patriarchal structure and character. Furthermore, we discussed in detail the household codes in antiquity and in the New Testament and the relationship of texts from the realm of Hellenistic philosophy of the Stoics as to the household code in Colossians epistle. Furthermore, we presented in detail the relationship between house and worship and we examined the cultural and social background of the time. Then, we discussed the interpretation of these verses by the modern interpretive memorandums. Finally, the second part of this study contains an extensive analysis and interpretation of passages that deal with residential codes.

description: The aim of the present master theses is the study of the so-called 'improved' Byzantine painting in Greece during the 19th century through the work of one of the most representative painters of this stylistic trend, of Spyridon Chatzigiannopoulos (1820 - 1905). Initially, in the first part, exploring the historical roots and the aesthetic, theological, cultural and educational conditions of this informal stylistic trend, which was intended to reconcile the western art with the byzantine tradition (as it was perceived in the 19th century), we try to delimit the research field. In the second part, so as to give an example of this specific trend, we explore the life, the artistic conditions and the paintings of Spyridon Chatzigiannopoulos. The third part is related with the iconographic analysis of the the painter’s mural work in two churches at Athens, Saint Eirini Aiolou, Assumption of Theotokos (Chrysospyliotissa) and Assumption of Theotokos Hydra.

description: No abstracts are to be cited without prior reference to the author. Despite the economical importance of wild European sea bass, little is known concerning its spatial structure and dynamics. Yet, in a context of climate change, significant recruitment variability and a northward distribution shift of Northeast Atlantic sea bass have been observed over the past two decades. In the present study, we used coupled models (simulating hydrodynamics, transport and bioenergetics) over a period to investigate the impact, on nursery settlement, of contrasted hydroclimatic conditions in the Northeast Atlantic. Maps of larval dispersal as well as connectivity matrices between spawning grounds and coastal/estuarine nurseries showed significant spatio-temporal transport and growth variability whose relation to environmental factors is explored.
Vegetable sheep : a chemosystematic study of the Cassiniinae
Creators: name: Reid, Alan
Publisher: name: University of British Columbia
Year: 2009

description: It is well known that there are few places in the Asteraceae where generic limits are more difficult to apply in practice than in the tribe Gnaphalieae subtribe Cassiniinae. This is the subtribe of the paper daisies, the Edelweiss, the cudweeds. These species are characterised by discoid floral heads with papery involucral bracts. This thesis presents the results of an investigation of the flavonoid chemistry of the major species present in Australasia from which an attempt to infer taxonomic relationships among the species based on the combination of chemical, morphological and ecological characters is made. The exudate and vacuolar flavonoid profiles of six genera Cassinia R. Br., Ozothamnus R. Br., Raoulia Hook, f and Haeckeria F. Muell., Leucoqenes R. Br. and Lawrencella Anderberg were established. The exudate chemistry consists of chalcones, dihydrochalcones and flavanones, several of which lack B-ring oxygenation, and quercetin 3-0- and 7-0-methyl ethers. Vacuolar flavonoids include galangin, eriodictyol-7-O-methyl ether, and a series of kaempferol and quercetin glycosides. Several combinations of these compounds occur in the taxa studied. Species in this study form a number of relationships that show a strong correlation to geography, altitude and ecological conditions. The production of exudate flavonoids show a direct correlation to the amount of UV-B radiation. These relationships mimic the classical taxonomy proposed by Allan in 1961 for the New Zealand species and by Burbidge in 1958 for the Australian species. Differences in distribution of flavonoids are taken as evidence for recognition that the relationships between the genera are as complex as classical taxononomic studies suggest.

description: The Einstein--Cartan Theory (ECT) of gravity is a modification of General Relativity Theory (GRT), allowing space-time to have torsion, in addition to curvature, and relating torsion to the density of intrinsic angular momentum. This modification was put forward in 1922 by Elie Cartan, before the discovery of spin. Cartan was influenced by the work of the Cosserat brothers (1909), who considered besides an (asymmetric) force stress tensor also a moments stress tensor in a suitably generalized continuous medium.

description: Anomalous U(1)'s are ubiquitous in 4D chiral string models. Their presence crucially affects the process of moduli stabilisation and cannot be neglected in realistic set-ups. Their net effect in the 4D effective action is to induce a matter field dependence in the non-perturbative superpotential and a Fayet-Iliopoulos D-term. We study flux compactifications of IIB string theory in the presence of magnetised D7 branes. These give rise to anomalous U(1)'s that modify the standard moduli stabilisation procedure. We consider simple orientifold models to determine the matter field spectrum and the form of the effective field theory. We apply our results to one-modulus KKLT and multi-moduli large volume scenarios, in particular to the Calabi-Yau P^4_{[1,1,1,6,9]}. After stabilising the matter fields, the effective action for the Kahler moduli can acquire an extra positive term that can be used for de Sitter lifting with non-vanishing F- and D-terms. This provides an explicit realization of the D-term lifting proposal of hep-th/0309187.

The Effects of Robin Boundary Condition on Thermal Convection in a Rotating Spherical Shell

description: Convection in a spherical shell is widely used to model fluid layers of planets and stars. The choice of thermal boundary conditions in such models is not always straightforward. To understand the implications of this choice, we report on the effects of the thermal boundary condition on thermal convection, in terms of instability onset, fully developed transport properties and flow structure. We use the Boussinesq approximation, and impose a Robin boundary condition at the top. This enforces the temperature anomaly and its radial derivative to be linearly coupled with a proportionality factor $β$. Using the height H of the fluid layer, we introduce the non-dimensional Biot number Bi* = $β$H. Varying Bi* allows us to transition from fixed temperature for Bi* = +$\infty$, to fixed thermal flux for Bi* = 0. The bottom boundary of the shell is kept isothermal. We find that the onset of convection is only affected by Bi* in the non-rotating case. Far from onset, considering an effective Rayleigh number and a generalized Nusselt number, we show that the Nusselt and P{é}clet numbers follow standard universal scaling laws, independent of Bi* in all cases considered. However, the large-scale flow structure keeps the signature of the boundary condition with more vigorous large scales for smaller Bi* , even though the global heat transfer and kinetic energy are the same. Finally, for all practical purposes, the Robin condition can be safely replaced by a fixed flux when Bi* < 0.03 and by a fixed temperature for Bi* > 30.

description: No abstracts are to be cited without prior reference to the author. Marine fishes and invertebrates respond to ocean warming through distribution shifts, generally to higher latitudes and deeper waters. Consequently, fisheries should be affected by ‘tropicalization’ of catch. However, a signature of such warming effects on global catches has not been demonstrated.

description: No abstracts are to be cited without prior reference to the author. The North Sea has been identified as a ‘hotspot’ of marine climate change and has warmed by more than 1°C over the past 100 years. In accordance, several highly-cited studies have reported that over the past 30 years, various North Sea fish species have shown an apparent northward shift in distribution, and that the whole fish assemblage has ‘deepened’

description: The electron transport properties of hybrid ferromagnetic|normal metal structures such as multilayers and spin valves depend on the relative orientation of the magnetization direction of the ferromagnetic elements. Whereas the contrast in the resistance for parallel and antiparallel magnetizations, the so-called Giant Magnetoresistance, is relatively well understood for quite some time, a coherent picture for non-collinear magnetoelectronic circuits and devices has evolved only recently. We review here such a theory for electron charge and spin transport with general magnetization directions that is based on the semiclassical concept of a vector spin accumulation. In conjunction with first-principles calculations of scattering matrices many phenomena, e.g. the current-induced spin-transfer torque, can be understood and predicted quantitatively for different material combinations.

description: Η ταυτότητα ως έννοια που εμπεριέχει την ετερότητα και ιδιαίτερα η εθνική ταυτότητα υπόκειται σε διαδικασίες συνεχούς εξέλιξης και επαναδιαπραγμάτευσης στα πλαίσια μιας εξελισσόμενης κοινωνίας. Η διδασκαλία της λογοτεχνίας στο Λύκειο συχνά αποσπάται από τα πολιτισμικά συμφραζόμενα του κειμένου και εστιάζεται στη νοηματική ανάλυση, στη γλωσσική επεξεργασία, στη δομή και στην αφήγηση. Η εργασία, στην οποία συμπεριλαμβάνεται και μια διδακτική πρόταση στο διήγημα του Βιζυηνού, Μοσκώβ Σελήμ, επικεντρώνεται στις αναγνώσεις της εθνικής κυρίως ταυτότητας. Ως μεθοδολογικό-ερευνητικό εργαλείο επιλέγεται μετά την ανάγνωση/ανάλυση των κειμένων και την εστίαση στις λέξεις που καθορίζουν ταυτότητες η ποιοτική ανάλυση περιεχομένου σε συνδυασμό με τη θεωρία της αφήγησης. Στόχος η ανάγνωση της εθνικής ταυτότητας με βάση τις θεμελιακές κατηγορίες:κατασκευή της εθνικής ταυτότητας, υλικά, στοιχεία που συγκροτούν τον κορμό της εθνικής ταυτότητας, η ταυτότητα του πρωταγωνιστή και των άλλων προσώπων, οι προβληματισμοί, οι αμφισβητήσεις και η κριτική περί ταυτότητας που αναδεικνύουν τα λογοτεχνικά κείμενα και η επισήμανση της ύπαρξής τους στον σύγχρονο άνθρωπο, οι αφηγηματικές επιλογές των συγγραφέων και ο τρόπος που η αφήγηση αντικατοπτρίζει τον άλλο και τον εαυτό.
description: The identity as a concept that includes the notion of otherness and especially national identity is subject to processes of continuous evolution and renegotiation in the context of a developing society. Teaching literature at Senior High School often digresses from the cultural context of a passage and focuses on notional analysis, linguistic elaboration, structure and narration. This assignment, which includes a teaching proposal on Viziinos’s short story, Moskov Selim, focuses primarily on the approaches of national identity. After reading and analyzing the texts and focusing on words that determine identities, the research method chosen is qualitative content analysis combined with narration theory. The aim of this assignment is to approach national identity on the basis of the following fundamental categories: construction of national identity, materials, elements that comprise the body of national identity, the main character identity and that of others, the issues, doubts and criticism over identity that literary texts convey and emphasis on their existence to the contemporary reader, the narrative choices made by writers and the way narration reflects “the other” and “the self”.

description: No abstracts are to be cited without prior reference to the author. Arctic and Antarctic marine systems have in common high latitudes, large seasonal changes in light levels, cold air/ sea temperatures, and sea ice. In other ways they are strikingly different, including: geological structure; ice stability; and food webs. Both regions contain rapidly warming areas; reported climate impacts and future projections are dramatic. Effects of changing climate on oceanographic processes and food webs influence their fisheries in different ways. Life-history strategies of zooplankton (Antarctic krill and Calanus copepods in the Arctic) may affect future fisheries productivity. To explore potential future scenarios for each region; this paper: 1) considers characteristics (geographic, physical, biological) defining these ecosystems, and reviews impacts of climate change on key zooplankton; 2) summarizes existing fisheries; 3) synthesizes this information to envisage future scenarios; 4) considers implications for management. Published studies suggest that in the Arctic increased open water and primary/ secondary production may benefit fish stocks. Fisheries may see new mixes of species and enhanced biomass. In contrast, studies in the Southern Ocean suggest the potential for existing species to adapt is mixed and potential for invasion of pelagic finfish is low. Future fisheries may depend on currently existing species. Management approaches should anticipate climate-induced changing dynamics in these regions

description: We present a framework for robust electric network frequency (ENF) extraction from real-world audio recordings, featuring multi-tone ENF harmonic enhancement and graph-based optimal harmonic selection. Specifically, We first extend the recently developed single-tone ENF signal enhancement method to the multi-tone scenario and propose a harmonic robust filtering algorithm (HRFA). It can respectively enhance each harmonic component without cross-component interference, thus further alleviating the effects of unwanted noise and audio content on the much weaker ENF signal. In addition, considering the fact that some harmonic components could be severely corrupted even after enhancement, disturbing rather than facilitating ENF estimation, we propose a graph-based harmonic selection algorithm (GHSA), which finds the optimal combination of harmonic components for more accurate ENF estimation. Noticeably, the harmonic selection problem is equivalently formulated as a maximum weight clique (MWC) problem in graph theory, and the Bron-Kerbosch algorithm (BKA) is adopted in the GHSA. With the enhanced and optimally selected harmonic components, both the existing maximum likelihood estimator (MLE) and weighted MLE (WMLE) are incorporated to yield the final ENF estimation results. The proposed framework is extensively evaluated using both synthetic signals and our ENF-WHU dataset consisting of $130$ real-world audio recordings, demonstrating substantially improved capability of extracting the ENF from realistically noisy observations over the existing single- and multi-tone competitors. This work further improves the applicability of the ENF as a forensic criterion in real-world situations.

description: No abstracts are to be cited without prior reference to the author. Future projections of global shifts in species' distributions under climatic scenarios were evaluated using three commonly applied habitat modeling approaches. Current ranges were determined using presence-only occurrence data and environmental variables, including sea temperature, bathymetry, salinity, primary production, ice concentration and distance to coast. Distributions were then projected under climatic scenarios to show the potential for range shifts. This study subsequently investigated the potential implications of climate-induced changes in relative habitat suitability on fisheries catch potential, and profitability by linking species distribution modeling with a cost-benefit analysis at a regional level, using a set of key species in UK waters as a case study. The sensitivity of results to variation in key variables and uncertainties in the modeling procedure was investigated using a set of scenarios and a multi-model approach. The three species distribution models provide a consensus for a poleward shift in global species' distributions. Furthermore, total maximum catch potential is projected to decrease within the UK EEZ by 2050 using all model combinations

description: We have identified a large-scale structure at z~0.73 in the COSMOS field, coherently described by the distribution of galaxy photometric redshifts, an ACS weak-lensing convergence map and the distribution of extended X-ray sources in a mosaic of XMM observations. The main peak seen in these maps corresponds to a rich cluster with Tx= 3.51+0.60/-0.46 keV and Lx=(1.56+/-0.04) x 10^{44} erg/s ([0.1-2.4] keV band). We estimate an X-ray mass within $r500$ corresponding to M500~1.6 x 10^{14} Msun and a total lensing mass (extrapolated by fitting a NFW profile) M(NFW)=(6+/-3) x 10^15 Msun. We use an automated morphological classification of all galaxies brighter than I_AB=24 over the structure area to measure the fraction of early-type objects as a function of local projected density Sigma_10, based on photometric redshifts derived from ground-based deep multi-band photometry. We recover a robust morphology-density relation at this redshift, indicating, for comparable local densities, a smaller fraction of early-type galaxies than today. Interestingly, this difference is less strong at the highest densities and becomes more severe in intermediate environments. We also find, however, local "inversions'' of the observed global relation, possibly driven by the large-scale environment. In particular, we find direct correspondence of a large concentration of disk galaxies to (the colder side of) a possible shock region detected in the X-ray temperature map and surface brightness distribution of the dominant cluster. We interpret this as potential evidence of shock-induced star formation in existing galaxy disks, during the ongoing merger between two sub-clusters.
