description: We present Spitzer Space Telescope and Chandra X-ray Observatory observations of the composite Galactic supernova remnant Kes 75 (G29.7-0.3). We use the detected flux at 24 microns and hot gas parameters from fitting spectra from new, deep X-ray observations to constrain models of dust emission, obtaining a dust-to-gas mass ratio M_dust/M_gas ~0.001. We find that a two-component thermal model, nominally representing shocked swept-up interstellar or circumstellar material and reverse-shocked ejecta, adequately fits the X-ray spectrum, albeit with somewhat high implied densities for both components. We surmise that this model implies a Wolf-Rayet progenitor for the remnant. We also present infrared flux upper limits for the central pulsar wind nebula.

description: The elliptical power-law (EPL) model of the mass in a galaxy is widely used in strong gravitational lensing analyses. However, the distribution of mass in real galaxies is more complex. We quantify the biases due to this model mismatch by simulating and then analysing mock {\it Hubble Space Telescope} imaging of lenses with mass distributions inferred from SDSS-MaNGA stellar dynamics data. We find accurate recovery of source galaxy morphology, except for a slight tendency to infer sources to be more compact than their true size. The Einstein radius of the lens is also robustly recovered with 0.1% accuracy, as is the global density slope, with 2.5% relative systematic error, compared to the 3.4% intrinsic dispersion. However, asymmetry in real lenses also leads to a spurious fitted `external shear' with typical strength, $γ_{\rm ext}=0.015$. Furthermore, time delays inferred from lens modelling without measurements of stellar dynamics are typically underestimated by $\sim$5%. Using such measurements from a sub-sample of 37 lenses would bias measurements of the Hubble constant $H_0$ by $\sim$9%. Although this work is based on a particular set of MaNGA galaxies, and the specific value of the detected biases may change for another set of strong lenses, our results strongly suggest the next generation cosmography needs to use more complex lens mass models.

Phaeoseptaceae (Pleosporales) was introduced by Hyde et al. (2018) for Phaeoseptum which was previously placed in Halotthiaceae (Zhang et al. 2013). Phaeoseptum is a monotypic genus and includes two marine species: P. carolshearerianum on decaying wood of Avicennia marina, and P. manglicola on decaying wood of Avicennia marina and Suaeda monoica (Dayarathne et al. 2020a). This is the first record of the family in the marine fungi checklist.

Galaxy disk

description: Galactic Open Clusters (OCs) are crucial to investigate the formation and evolution of the Galactic disc. The Open Clusters Chemical Abundance from Spanish Observatory survey (OCCASO) aims to provide high precision radial velocity (typical uncertainties between 100 to 200 m/s) and to determine abundances for more than 20 chemical species in around 30 Northern OCs (Casamiquela et al, 2016). We use high resolution (R > 65,000) high signal-to-noise (∼70) spectra of at least 6 Red Clump stars for each cluster. In this work we combined Gaia DR2 mean  parallaxes and proper motions, and OCCASO radial velocities to obtain 3D spatial velocities and determine the orbits of the clusters. We also study Galactic trends with Galactocentric radius and age of Fe peak and alpha elements for the 18 OCs currently observed in the OCCASO survey, and we compare them with chemo-dynamical models of the Milky Way.

description: Solving the electronic Schrödinger equation for changing nuclear coordinates provides access to the Born-Oppenheimer potential energy surface. This surface is the key starting point for almost all theoretical studies of chemical processes in electronic ground and excited states (including molecular structure prediction, reaction mechanism elucidation, molecular property calculations, quantum and molecular dynamics). Electronic structure models aim at a sufficiently accurate approaximation of this surface. They have therefore become a cornerstone of theoretical and computational chemistry, molecular physics, and materials science. In this work, we elaborate on general features of approximate electronic structure models such as accuracy, transferability, and general applicability in order to arrive at a perspective for future developments, of which a vanguard has already arrived. Our quintessential proposition is that meaningful quantum mechanical predictions for chemical phenomena require system-specific uncertainty information for each and every electronic structure calculation, if objective conclusions shall be drawn with confidence.

description: A non-linear conjugate gradient optimization scheme is used to obtain excitation energies within the Random Phase Approximation (RPA). The solutions to the RPA eigenvalue equation are located through a variational characterization using a modified Thouless functional, which is based upon an asymmetric Rayleigh quotient, in an orthogonalized atomic orbital representation. In this way, the computational bottleneck of calculating molecular orbitals is avoided. The variational space is reduced to the physically-relevant transitions by projections. The feasibility of an RPA implementation scaling linearly with system size, N, is investigated by monitoring convergence behavior with respect to the quality of initial guess and sensitivity to noise under thresholding, both for well- and ill-conditioned problems. The molecular- orbital-free algorithm is found to be robust and computationally efficient providing a first step toward a large-scale, reduced complexity calculation of time-dependent optical properties and linear response. The algorithm is extensible to other forms of time-dependent perturbation theory including, but not limited to, time-dependent Density Functional theory.

description: Automated Vehicle License Plate (VLP) detection and recognition have ended up being a significant research issue as of late. VLP localization and recognition are some of the most essential techniques for managing traffic using digital techniques. In this paper, four smart systems are developed to recognize Egyptian vehicles license plates. Two systems are based on character recognition, which are (System1, Characters Recognition with Classical Machine Learning) and (System2, Characters Recognition with Deep Machine Learning). The other two systems are based on the whole plate recognition which are (System3, Whole License Plate Recognition with Classical Machine Learning) and (System4, Whole License Plate Recognition with Deep Machine Learning). We use object detection algorithms, and machine learning based object recognition algorithms. The performance of the developed systems has been tested on real images, and the experimental results demonstrate that the best detection accuracy rate for VLP is provided by using the deep learning method. Where the VLP detection accuracy rate is better than the classical system by 32%. However, the best detection accuracy rate for Vehicle License Plate Arabic Character (VLPAC) is provided by using the classical method. Where VLPAC detection accuracy rate is better than the deep learning-based system by 6%. Also, the results show that deep learning is better than the classical technique used in VLP recognition processes. Where the recognition accuracy rate is better than the classical system by 8%. Finally, the paper output recommends a robust VLP recognition system based on both statistical and deep machine learning.

description: We investigate B3 mSUGRA models, where the lightest scalar tau, stau_1, is the LSP. B3 models allow for lepton number and R-parity violation; the LSP can thus decay. We assume one non-zero B3 coupling lambda'_ijk at M_GUT, which generates further B3 couplings at M_Z. We study the RGEs and give numerical examples. The new couplings lead to additional stau_1 decays, providing distinct collider signatures. We classify the stau_1 decays and describe their dependence on the mSUGRA parameters. We exploit our results for single slepton production at the LHC. As an explicit numerical example, we investigate single smuon production, focussing on like-sign dimuons in the final state. Also considered are final states with three or four muons.

description: The formation, development and impact of slow shocks in the upstream region of reconnecting current layers are explored. Slow shocks have been documented in the upstream region of magnetohydrodynamic (MHD) simulations of magnetic reconnection as well as in similar simulations with the {\it kglobal} kinetic macroscale simulation model. They are therefore a candidate mechanism for preheating the plasma that is injected into the current layers that facilitate magnetic energy release in solar flares. Of particular interest is their potential role in producing the hot thermal component of electrons in flares. During multi-island reconnection, the formation and merging of flux ropes in the reconnecting current layer drives plasma flows and pressure disturbances in the upstream region. These pressure disturbances steepen into slow shocks that propagate along the reconnecting component of the magnetic field and satisfy the expected Rankine-Hugoniot jump conditions. Plasma heating arises from both compression across the shock and the parallel electric field that develops to maintain charge neutrality in a kinetic system. Shocks are weaker at lower plasma $β$, where shock steepening is slow. While these upstream slow shocks are intrinsic to the dynamics of multi-island reconnection, their contribution to electron heating remains relatively minor compared with that from Fermi reflection and the parallel electric fields that bound the reconnection outflow.

The design and performance evaluation of a pre-emphasis network for FM voice communication
Creators: name: Beaulieu, Norman C.
Publisher: name: University of British Columbia
Year: 2010

description: The pre-emphasis problem for FM radiotelephony over an additive white Gaussian noise channel is investigated. A Gaussian model and an experimentally measured frequency spectrum density for speech are used to solve the optimum filtering problem analytically. The optimum pre-emphasis characteristic is expressed in terms of the message spectral power density, the noise power density and the LaGrange multiplier. An iterative algorithm for the determination of the multiplier is presented and solved numerically for typical values of the signal-to-noise ratio. The optimum filter is unrealizable. It is approximated by a whitening filter in cascade with a two pole network. The selection of the pole positions involves a trade-off between mean square error performance and spectral compression. The transmitted signal spectra are computed numerically for three choices of pole positions and compared to those for the currently employed prefilter. The mean square error is computed and compared to the optimum mean square error for typical values of the signal-to-noise ratio. The new designs have less distortion than the present design. The roll-off rate of the spectrum in the adjacent channel region is determined to be greater than 4 for the proposed filter. This compares favourably with the rate of 2 for the current filter. Interference coefficients are defined to measure the interference between adjacent channel signals. The cases of voice-to-voice, voice-to-digital and digital-to-voice interference are investigated. Four types of data signals are considered, PAM signals with a = 0 and a = 1, MSK and PSK signals. An improvement ranging from 4 to 19 dB is noted for the new network. The improvement is greatest for the bandlimited PAM signals. The effects of a different speech model on the previous results are investigated. Spectra and interference coefficients are computed for a second speech spectral density function. A computer simulation verifies that the proposed new design offers improved performance.

description: A year following the initial COVID-19 outbreak in China, many countries have approved emergency vaccines. Public-health practitioners and policymakers must understand the predicted populational willingness for vaccines and implement relevant stimulation measures. This study developed a framework for predicting vaccination uptake rate based on traditional clinical data-involving an autoregressive model with autoregressive integrated moving average (ARIMA)- and innovative web search queries-involving a linear regression with ordinary least squares/least absolute shrinkage and selection operator, and machine-learning with boost and random forest. For accuracy, we implemented a stacking regression for the clinical data and web search queries. The stacked regression of ARIMA (1,0,8) for clinical data and boost with support vector machine for web data formed the best model for forecasting vaccination speed in the US. The stacked regression provided a more accurate forecast. These results can help governments and policymakers predict vaccine demand and finance relevant programs.

description: We theoretically demonstrate the formation of different kinds of two-dimensional split-ring arrays in both triangular and square lattices by one-step holographic interference. The slit width of the split-ring can be adjusted by proper polarization configurations. The dimension of the rings can be adjusted easily by using different wavelengths for interference, so the resonant frequency of the split-rings can be obtained in a wide range. Our theory is also proved in experiment. Our work would extend the application of holographic lithography to the fabrication of magnetic metamaterials.

description: Palomar 6 (Pal~6) is a moderately metal-poor globular cluster projected towards the Galactic bulge. A full analysis of the cluster can give hints on the early chemical enrichment of the Galaxy and a plausible origin of the cluster. The aim of this study is threefold: a detailed analysis of high-resolution spectroscopic data obtained with the UVES spectrograph at the Very Large Telescope (VLT) at ESO, the derivation of the age and distance of Pal~6 from Hubble Space Telescope (HST) photometric data, and an orbital analysis to determine the probable origin of the cluster. High-resolution spectra of six red giant stars in the direction of Palomar 6 were obtained at the $8$m VLT UT2-Kueyen telescope equipped with the UVES spectrograph in FLAMES$+$UVES configuration. Spectroscopic parameters were derived through excitation and ionisation equilibrium of \ion{Fe}{I} and \ion{Fe}{II} lines, and the abundances were obtained from spectrum synthesis. From HST photometric data, the age and distance were derived through a statistical isochrone fitting. Finally, a dynamical analysis was carried out for the cluster assuming two different Galactic potentials. Four stars that are members of Pal~6 were identified in the sample, which gives a mean radial velocity of $174.3\pm1.6$ km\,s$^{-1}$ and a mean metallicity of [Fe/H]$\,=-1.10\pm0.09$ for the cluster. We found an enhancement of $α$-elements (O, Mg, Si, and Ca) $0.29

description: The principles of statistical mechanics and information theory play an important role in learning and have inspired both theory and the design of numerous machine learning algorithms. The new aspect in this paper is a focus on integrating feedback from the learner. A quantitative approach to interactive learning and adaptive behavior is proposed, integrating model- and decision-making into one theoretical framework. This paper follows simple principles by requiring that the observer's world model and action policy should result in maximal predictive power at minimal complexity. Classes of optimal action policies and of optimal models are derived from an objective function that reflects this trade-off between prediction and complexity. The resulting optimal models then summarize, at different levels of abstraction, the process's causal organization in the presence of the learner's actions. A fundamental consequence of the proposed principle is that the learner's optimal action policies balance exploration and control as an emerging property. Interestingly, the explorative component is present in the absence of policy randomness, i.e. in the optimal deterministic behavior. This is a direct result of requiring maximal predictive power in the presence of feedback.

description: We present resolved-star VI photometry of the Local Group dwarf irregular galaxy IC1613 reaching I~23.5, obtained with the wide-field camera at the 2.5m Isaac Newton Telescope. A fit to the stellar density distribution shows an exponential profile of scale length 2.9' +/- 0.1 and gives a central surface brightness mu_V,0 = 22.7 +/- 0.6. The significant number of red giant branch (RGB) stars present in the outer part of our images (r > 16.5') indicates that the galaxy is actually more extended than previously estimated. A comparison of the color-magnitude diagrams (CMDs) as a function of galactocentric distance shows a clear gradient in the age of its population, the scale length increasing with age, while we find no evidence of a metallicity gradient from the width of the RGB. We present quantitative results of the recent star formation history from a synthetic CMD analysis using IAC-STAR. We find a mean star formation rate of (1.6 +/- 0.8) x 10^{-3} Mo/yr/kpc^2 in the central r < 2.5' for the last 300 Myr.

description: It was 1967 when Pier Paolo Pasolini contributed the episode La terra vista dalla Luna to the anthology film Le streghe, a project in which Luchino Visconti, Mauro Bolognini, Franco Rossi and Vittorio De Sica also participated. Pasolini, alongside an apparently more ‘classic’ subject, adds a comic script, a sort of storyboard that the author also conceives as an autonomous work. The experiments with color that will be the basis of technical innovations in the short film, can also already be glimpsed. Pasolini’s comic script can be read as a text-in-itself using the critical and theoretical tools usually linked to the studies of comics and graphic novels. The author himself considers it an independent work, part of a hypothetical more impressive comic project that never took place. It is particularly useful to situate Pasolini's work within contemporary and previous comic publications, especially if we think of the impact that his ability to manipulate and transform media has had, both within his production, but also outside of expressions crossed, from poetry to theater through cinema. In the article, La Terra vista dalla Luna is discussed as a project that participates in a broader conception of cultural work that crosses languages and experiments with narrative methods, but that also exists as an autonomous fragment of text, in turn the bearer of an internal hybridization between sign and word. Starting from theoretical tools typical of studies on comics, we can find the specific methods of use of the medium through three distinct elements: the breaking of the ‘cage’; the ‘flaking’ of the sign; and the contamination between legitimated and popular cultural productions. These elements show how Pasolini was absolutely contemporary to the renewal of the genre witnessed in those years and, in some specific situations – technical, content-related and linked in a more general way to the very conception of the type of language – anticipated subsequent evolutions.

description: This thesis investigates Henry II’s relationship with the Church in his continental domains focusing on Normandy, Anjou, Maine, the Touraine, and Aquitaine during his reign as king of England from 1154 to 1189. To examine this relationship the thesis uses traditional methods which historians have long used in studies focusing on the Church in England, but only rarely applied to the Continent. These methods include an investigation of bishops’ backgrounds, familial links, and relationships with the king as demonstrated through their attendance at court, royal service, and positions in local society. It will examine how religious institutions, both secular and monastic, sought out the authority of Henry II and how as patron Henry expressed his authority through the extant royal charter corpus. It employs over 350 royal charters for religious institutions to assess royal patronage, the nature of the king’s patronage, and to determine the demand for royal patronage and charters as both reflect ecclesiastical views of the king and his authority. Henry II’s acta form the main resource for this research, but this thesis also makes use of the charters and letters of the institutions and individuals it investigates alongside contemporary narratives to create a fuller picture of his episcopal relationships. Through these methodologies and the in-depth analysis provided, this thesis offers a better understanding of Henry’s relationship with the Church on the Continent and the recognition of his authority.

description: We present velocity-resolved spectro-astrometric imaging of the 4.7 $μ$m rovibrational lines of CO gas in protoplanetary disks using the CRIRES high resolution infrared spectrometer on the Very Large Telescope (VLT). The method as applied to three disks with known dust gaps or inner holes out to 4-45 AU (SR 21, HD 135344B and TW Hya) achieves an unprecedented spatial resolution of $0.1-0.5$ AU. While one possible gap formation mechanism is dynamical clearing by giant planets, other equally good explanations (stellar companions, grain growth, photo-evaporation) exist. One way of distinguishing between different scenarios is the presence and distribution of gas inside the dust gaps. Keplerian disk models are fit to the spectro-astrometric position-velocity curves to derive geometrical parameters of the molecular gas. We determine the position angles and inclinations of the inner disks with accuracies as good as 1-2\degr, as well as the radial extent of the gas emission. Molecular gas is detected well inside the dust gaps in all three disks. The gas emission extends to within a radius of 0.5 AU for HD 135344B and to 0.1 AU for TW Hya, supporting partial clearing by a $< 1-10 M_{\rm Jup}$ planetary body as the cause of the observed dust gaps, or removal of the dust by extensive grain coagulation and planetesimal formation. The molecular gas emission in SR 21 appears to be truncated within $\sim 7 $AU, which may be caused by complete dynamical clearing by a more massive companion. We find a smaller inclination angle of the inner disk of TW Hya than that determined for the outer disk, suggestive of a disk warp. We also detect significant azimuthal asymmetries in the SR 21 and HD 135344B inner disks.

description: A novel approach to study the properties of models with quantum-deformed relativistic symmetries relies on a noncommutative space of worldlines rather than the usual noncommutative spacetime. In this setting, spacetime can be reconstructed as the set of events, that are identified as the crossing of different worldlines. We lay down the basis for this construction for the $κ$-Poincaré model, analyzing the fuzzy properties of $κ$-deformed time-like worldlines and the resulting fuzziness of the reconstructed events.

description: The Cygnus Loop (G74.0-8.5) is a very well-known nearby supernova remnant (SNR) in our Galaxy. Thanks to its large size, brightness, and angular offset from the Galactic plane, it has been studied in detail from radio to $γ$-ray emission. The $γ$ -rays probe the populations of energetic particles and their acceleration mechanisms at low shock speeds. We present an analysis of the $γ$-ray emission detected by the Large Area Telescope on board the Fermi Gamma-ray Space Telescope over 11 years in the region of the Cygnus Loop. We performed detailed morphological and spectral studies of the $γ$-ray emission toward the remnant from 100 MeV to 100 GeV and compared it with X-ray, UV, optical, and radio images. The higher statistics with respect to the previous studies enabled us to decompose the emission from the remnant into two morphological components to model its nonthermal multiwavelength emission. The extended $γ$-ray emission is well correlated with the thermal X-ray and UV emission of the SNR. Our morphological analysis reveals that a model considering two contributions from the X-ray and the UV emission regions is the best description of the $γ$-ray data. Both components show a curved spectrum, but the X-ray component is softer and more curved than the UV component, suggesting a different physical origin. The multiwavelength modeling of emission toward the SNR suggests that the nonthermal radio and $γ$-ray emission associated with the UV component is mostly due to the reacceleration of preexisting cosmic rays by radiative shocks in the adjacent clouds, while the nonthermal emission associated with the X-ray component arises from freshly accelerated cosmic rays.

The Mandela Legacy - The Repetition of Violence.pdf

description: Nelson Mandela was both a man of peace and a leader that deployed violence during South Africa's national liberation struggle. This ambiguous legacy, and particuularly the part which involved the resort to armed struggle, creates a context for the use of violence in the post-apartheid era by certain formations. It is argued that such violence, however, to the extent that such formations eschew other channels of democratic expression, closes downs democratic space and detracts from processes of strengthening democracy. This situation, this article suggests, calls on proponents of non-violence to more assertively and skillfully challenge those who espouse violence, even if it means revisiting and reframing the strategies used by Nelson Mandela.

description: We investigate the derivation of reggeon transition vertices from Lipatov's gauge invariant effective action for high energy processes in QCD. In particular we address the question of longitudinal integrations in order to reduce the vertices into the required purely transverse form. We explicitly derive the BFKL-kernel and verify vanishing of the 2-to-3 reggeon transition vertex. First results on the derivation of the 2-to-4 reggeon transition vertex are discussed.

description: We present a method to derive outflow velocities in the solar corona using different data sets including solar wind mass flux coming from the SWAN/SOHO instrument, electron density values from LASCO-C2 and interplanetary solar wind velocities derived from ground-based Interplanetary Scintillation Observations (IPS). In a first step, we combine the LASCO electron densities at 6 solar radii and the IPS velocities, and compare the product to the SWAN mass fluxes. It is found that this product represents the actual mass flux at 6 solar radii for the fast wind, but not for the slow wind. In regions dominated by the slow wind, the fluxes derived from SWAN are systematically smaller. This is interpreted as a proof that the fast solar wind has reached its terminal velocity at about 6 solar radii and expands with constant velocity beyond this distance. On the contrary, the slow solar wind has reached only half of its terminal value and is thus accelerated further out. In a second step, we combine the LASCO-C2 density profiles and the SWAN flux data to derive velocity profiles in the corona between 2.5 and 6 solar radii. Such profiles can be used to test models of the acceleration mechanism of the fast solar wind.

Perturbative quantum consistency near black-hole horizon formation

description: We study the prelude to black-hole formation using a suspended shell composed of physical matter that fulfills the dominant energy condition. Here, the collapse of the shell is brought to rest when the formation of the horizon is imminent but has not yet occurred. As the main achievement of this work, we obtain the Feynman propagator which connects the interior and the exterior of the shell within two local coordinate patches. It is derived by drawing an analogy to the propagation of light across interfaces that separate regions with different susceptibilities inside a medium. As a first application, we use this propagator to determine the vacuum persistence amplitude in the presence of external sources. On timescales much shorter than the Page time, we find that the amplitude builds up with time yet remains consistent with perturbative unitarity.

description: Abraxas niphonibia Wehrli
(Figs 15a, 15b, 58)
cf. Abraxas satoi, nec Inoue: iBOL 2016: GBIF occurrence 1415518380 (Moneron).
Material examined. 1 ♀, Moneron, 26.VII.2021.
Distribution. Russia (S RFE: * Moneron, Kunashir; S Khabarovskii Krai, S Amurskaya Oblast, Primorskii Krai), Japan (Hokkaido, Honshu, Shikoku, Kyushu, Tsushima, Yaku, Oshima, Okinawa), North Korea, South Korea, NE China;?SW China (Sichuan, A. niphonibia wassuensis Wehrli).
Remarks. The finding of A. niphonibia in Moneron extends its general range to the north along the Pacific islands. The examined specimen possesses uncharacteristic broad and dark spots on the wings, but its genitalia (Fig. 58) indicate its belonging to A. niphonibia, despite of some pathological deformation in the sternal area. The discussed female quite matches to the photo of a moth from Moneron in BOLD, identified as “ Abraxas AH 01Ru” (Sample ID: GWOSC549-10, labelled as: “ Russia, 46.237 N, 141.228 E, 26.VII.2009, Saldaitis leg.”; also, in the GBIF as “BOLD: AAF2823 (cf. Abraxas satoi)”: iBOL 2016). This specimen shares BIN ID: AAF2823 with a number of other specimens identified as “ Abraxas satoi ” from Japan and from China, Shandong (Table 2). Probably these specimens are also A. niphonibia, what doesn’t contradict with their wing pattern. Besides, BOLD samples of “ Abraxas miranda ” (Sequence ID: GBMND20868-21, GBMIN22871-13), “ Abraxas latifasciata ” (Sequence ID: GBMNF21036-22), and “ Abraxas fulvobasalis ” (Sequence ID: GBMNF21033-22), clustering together with “ Abraxas satoi ”, with the nucleotides imported from GenBank and with the lacking images of the moths, can as well be A. niphonibia. But they need to be examined morphologically, as different species of geometrids sometimes possess same COI barcodes (Makhov et al. 2021). Status of A. n. wassuensis needs to be revised, as the structure of its male genitalia (Wehrli 1939: 288) differs from that in A. niphonibia.
In Japan the larvae of A. niphonibia feed on Celastrus orbiculatus and Tripterygium regelii (Celastraceae); in continental Asia, probably, on Euonymus (Celastraceae) as well, as A. niphonibia has a much wider northward distribution here than the ranges of Celastrus and Tripterygium.

description: We present a sample of 29 galaxy clusters from the XMM-LSS survey over an area of some 5deg2 out to a redshift of z=1.05. The sample clusters, which represent about half of the X-ray clusters identified in the region, follow well defined X-ray selection criteria and are all spectroscopically confirmed. For all clusters, we provide X-ray luminosities and temperatures as well as masses. The cluster distribution peaks around z=0.3 and T =1.5 keV, half of the objects being groups with a temperature below 2 keV. Our L-T(z) relation points toward self-similar evolution, but does not exclude other physically plausible models. Assuming that cluster scaling laws follow self-similar evolution, our number density estimates up to z=1 are compatible with the predictions of the concordance cosmology and with the findings of previous ROSAT surveys. Our well monitored selection function allowed us to demonstrate that the inclusion of selection effects is essential for the correct determination of the evolution of the L-T relation, which may explain the contradictory results from previous studies. Extensive simulations show that extending the survey area to 10deg2 has the potential to exclude the non-evolution hypothesis, but that constraints on more refined ICM models will probably be limited by the large intrinsic dispersion of the L-T relation. We further demonstrate that increasing the dispersion in the scaling laws increases the number of detectable clusters, hence generating further degeneracy [in addition to sigma8, Omega_m, L(M,z) and T(M,z)] in the cosmological interpretation of the cluster number counts. We provide useful empirical formulae for the cluster mass-flux and mass-count-rate relations as well as a comparison between the XMM-LSS mass sensitivity and that of forthcoming SZ surveys.
