description: Η παρούσα εργασία πραγματεύεται ένα θέμα ιδιαιτέρως σημαντικό, την αντιμετώπιση των ψυχοκοινωνικών δυσκολιών παιδιών με μαθησιακές δυσκολίες. Η ύπαρξη των μαθησιακών δυσκολιών στα παιδιά είναι ένα ζήτημα που απασχολεί καθημερινά τους εκπαιδευτικούς, τους γονείς αλλά και τα ίδια τα παιδιά που αντιμετωπίζουν αυτές τις δυσκολίες. Η παρούσα μελέτη αποτελεί μια προσπάθεια καταγραφής του τρόπου με τον οποίο, ειδικοί παιδαγωγοί της πρωτοβάθμιας εκπαίδευσης, αντιμετωπίζουν τις ψυχοκοινωνικές δυσκολίες των παιδιών με μαθησιακές δυσκολίες. Πρόκειται για ένα θέμα ιδιαίτερης σημασίας το οποίο ωστόσο, ελάχιστα έχει διερευνηθεί όπως προκύπτει από την περιορισμένη, σχετικά με αυτό, βιβλιογραφία. Σκοπός της παρούσας έρευνας, είναι αρχικά η διερεύνηση της ύπαρξης ψυχοκοινωνικών δυσκολιών σε παιδιά με μαθησιακές δυσκολίες με βάση τις απόψεις των ειδικών παιδαγωγών πρωτοβάθμιας εκπαίδευσης, καθώς και η διερεύνηση των πρακτικών και των ενεργειών που υιοθετούν για την αντιμετώπιση των δυσκολιών αυτών.
description: This master thesis discusses an issue particularly important, the address of psychosocial difficulties of children with learning difficulties. The presence of learning disabilities in children is a matter of daily concern for teachers, parents and children themselves. This study is an attempt to record the multiple ways that special educators of primary education use to face the psychosocial difficulties of children with learning difficulties. It is a matter of particular importance which, however, has not been explored in depth. The purpose of this research, is to investigate the existence of psychosocial difficulties in children with learning difficulties from the standpoint of special educators of primary education, plus to explore the practices and actions the special educators adopt to address these difficulties.
Post-Newtonian gravitational radiation and equations of motion via direct integration of the relaxed Einstein equations. IV. Radiation reaction for binary systems with spin-spin coupling

description: Using post-Newtonian equations of motion for fluid bodies that include radiation-reaction terms at 2.5 and 3.5 post-Newtonian (PN) order O[(v/c)^5] and O[(v/c)^7] beyond Newtonian order), we derive the equations of motion for binary systems with spinning bodies, including spin-spin effects. In particular we determine the effects of radiation-reaction coupled to spin-spin effects on the two-body equations of motion, and on the evolution of the spins. We find that radiation damping causes a 3.5PN order, spin-spin induced precession of the individual spins. This contrasts with the case of spin-orbit coupling, where there is no effect on the spins at 3.5PN order. Employing the equations of motion and of spin precession, we verify that the loss of total energy and total angular momentum induced by spin-spin effects precisely balances the radiative flux of those quantities calculated by Kidder et al.

Publisher: name: University of British Columbia
Year: 2009

description: Ultrafast mid-infrared laser pulse generation using optical semiconductor switching is investigated experimentally for application to subpicosecond CO₂ laser pulse generation at 10.6 μm. Time-resolved infrared measurements, which are based on cross-correlation and reflection-reflection correlation techniques, are used to determine the duration of the reflected infrared pulses from a GaAs infrared reflection switch. These time-resolved measurements together with time-integrated measurements are used to derive a model describing the behaviour of the GaAs infrared reflection switch. it is found that diffusion and two-body recombination whose rate is taken to be density-dependent, can accurately describe the ultrafast infrared reflectivity switching process in GaAs. We have also in vestigated some novel semiconductor materials with ultrafast recombination lifetimes for ultrafast semiconductor switching application. A molecular beam epitaxy low tempera ture grown GaAs (LT-GaAs) and radiation damaged GaAs (RD-GaAs) are successfully used to switch out ultrashort CO₂ laser pulses. Application of the time-resolved crosscorrelation technique to nonequilibrium carrier lifetime measurements in highly excited LT-GaAs, RD-GaAs, and In₀.₈₅Ga₀.₁₅As/GaAs relaxed superlattice structure are found to be in good agreement with other reported techniques. As an application to semicon ductor probing, ultrafast infrared transmission experiments are conducted to determine the absorption of infrared pulses in Si of various dopings after free carriers have been generated by absorption of a subpicosecond laser pulse of above band gap photon en ergy. By fitting the experimental data to a theoretical model, the free-carrier absorption cross-sections and the momentum relaxation times are calculated.

description: We investigate lattice simulations of scalar and nonabelian gauge fields in Minkowski space-time. For SU(2) gauge-theory expectation values of link variables in 3+1 dimensions are constructed by a stochastic process in an additional (5th) ``Langevin-time''. A sufficiently small Langevin step size and the use of a tilted real-time contour leads to converging results in general. All fixed point solutions are shown to fulfil the infinite hierarchy of Dyson-Schwinger identities, however, they are not unique without further constraints. For the nonabelian gauge theory the thermal equilibrium fixed point is only approached at intermediate Langevin-times. It becomes more stable if the complex time path is deformed towards Euclidean space-time. We analyze this behavior further using the real-time evolution of a quantum anharmonic oscillator, which is alternatively solved by diagonalizing its Hamiltonian. Without further optimization stochastic quantization can give accurate descriptions if the real-time extend of the lattice is small on the scale of the inverse temperature.

description: The purpose of the present thesis was the pilot planning and implementation of teaching Greek language to Albanian immigrant parents, with the ultimate aim of establishing these courses. Initially, we examined concepts and issues of migration and multilingualism in Albania and Greece and focused on the albanian community of Thessaloniki, where the research - action took place. Then, we analyzed the effect of bilingualism and characteristics of teaching Greek as a second language to adult immigrants. In addition, we referred in detail in the research – action, its educational process, its objectives, methods of data collection and processing and presented extensively the results of the questionnaires, the processing of the educational material and sociolinguistic observation. Furthermore, we dealt with the conclusions of such an argument and found appropriate ways of teaching the Greek language for this particular group of students.

description: Αντικείμενο της παρούσας μελέτης είναι η χρήση του ταφικού νομίσματος στη Μακεδονία. Τα χρονολογικά όρια του φαινομένου ορίζονται από τα τέλη του 6ου αι. π.Χ. μέχρι τα τέλη του 1ου αι. πΧ. Η μελέτη δεν περιλαμβάνει το σύνολο των νομισμάτων που προέκυψαν σε τάφους κατά τη διάρκεια των αιώνων στην Μακεδονία, αλλά περιέχει ένα μεγάλο και αντιπροσωπευτικό δείγμα από το σύνολο του μακεδονικού χώρου αντλώντας από βιβλιογραφικό υλικό του τελευταίου μισού αιώνα περίπου. Η εργασία χωρίζεται σε δύο μέρη: το κυρίως κείμενο και τους καταλόγους. Το κυρίως κείμενο διαρθρώνεται σε κεφάλαια, τα οποία συνεξετάζουν και τα δεδομένα των καταλόγων. Τα κεφάλαια όπου εξετάζεται ο χαρώνειος οβολός σε συνδυασμό με τα ιστορικά συμφραζόμενα κάθε περιόδου, αποτελούν και το μεγαλύτερο σε έκταση τμήμα της μελέτης. Στη συνέχεια, γίνεται μία σύντομη αναφορά στο σύνθετο φαινόμενο των ταφικών θησαυρών από τον 5ο αι. π.Χ. μέχρι τον 1ο αι. π.Χ. Σε ξεχωριστό κεφάλαιο αναλύονται εκτενέστερα οι περιπτώσεις ταφών με δανάκες-ψευδονομίσματα. Εξετάζεται η πιθανή σχέση-εξάρτηση τους από τους χαρώνειους οβολούς ή άλλα ταφικά δρώμενα. Το κείμενο κλείνει ένα σύντομο κεφάλαιο συμπερασμάτων. Στους καταλόγους που ακολουθούν καταγράφονται οι περιπτώσεις ταφών με χαρώνειο οβολό, ταφών με ταφικούς θησαυρούς και ταφών με δανάκες-ψευδονομίσματα. Τα άνωθι συνοδεύουν γραφήματα και πίνακες.
description: The object of this thesis is to thoroughly examine the use of death coin in Macedonia. The chronological range of the case study is defined from the late 6th until the 1st century B.C. The thesis does not refer to all coins found in tombs during the above mentioned centuries in Macedonia. Instead, it comprises a large cross-section of coins coming from the whole Macedonian territory and it is based on information from references of the last half century. The thesis consists of two parts: the main text and the catalogues. The main text is divided in chapters which, apart from their content, directly refer to the data in catalogues examining it. The chapters in which Charon’s obol (οβολός) is studied in connection with the historical context of each period constitute the most extensive part of the thesis. Furthermore, there is a brief reference to the complex case of burial treasures (ταφικοί θησαυροί) dated from the 5th to the 1st century B.C. In a separate chapter there is a detailed analysis on cases of tombs with ghost money-pseudocoins (δανάκες-ψευδονομίσματα). On this occasion a probable relation dependence of these coins on Charon’s obols or other burial procedure is also closely examined. The text is completed with a short chapter on conclusions and followed by catalogues which register the causes of tombs with Charon’s obol, burial treasures as well as with ghost money-pseudocoins. All research is clarified with graphs and charts.
Quiet-Sun hydrogen Lyman-alpha line profile derived from SOHO/SUMER solar-disk observations

description: The solar radiation in the Lyman-alpha spectral line of hydrogen plays a significant role in the illumination of chromospheric and coronal structures, such as prominences, spicules, chromospheric fibrils, cores of coronal mass ejections, and solar wind. Moreover, it is important for the investigation of the heliosphere, Earth's ionosphere, and the atmospheres of planets, moons, and comets. We derive a reference quiet-Sun Lyman-alpha spectral profile that is representative of the Lyman-alpha radiation from the solar disk during a minimum of solar activity. This profile can serve as an incident radiation boundary condition for the radiative transfer modelling of chromospheric and coronal structures. Because the solar radiation in the Lyman lines is not constant over time but varies significantly with the solar cycle, we provide a method for the adaptation of the incident radiation Lyman line profiles (Lyman-alpha and higher lines) to a specific date. Moreover, we analyse how the change in the incident radiation influences the synthetic spectra produced by the radiative transfer modelling. To take into account the Lyman-alpha variation with the solar cycle, we used the LISIRD composite Lyman-alpha$ index. To estimate the influence of the change in the incident radiation in the Lyman lines on the results of radiative transfer models, we used a 2D prominence fine structure model. The analysis of the influence of the change in the incident radiation shows that the synthetic spectra are strongly affected by the modification of the incident radiation boundary condition. The hydrogen H alpha line can also be considerably affected, despite the fact that the H alpha radiation from the solar disk does not vary with the solar cycle.

description: Influence maximization (IM) aims at maximizing the spread of influence by offering discounts to influential users (called seeding). In many applications, due to user's privacy concern, overwhelming network scale etc., it is hard to target any user in the network as one wishes. Instead, only a small subset of users is initially accessible. Such access limitation would significantly impair the influence spread, since IM often relies on seeding high degree users, which are particularly rare in such a small subset due to the power-law structure of social networks. In this paper, we attempt to solve the limited IM in real-world scenarios by the adaptive approach with seeding and diffusion uncertainty considered. Specifically, we consider fine-grained discounts and assume users accept the discount probabilistically. The diffusion process is depicted by the independent cascade model. To overcome the access limitation, we prove the set-wise friendship paradox (FP) phenomenon that neighbors have higher degree in expectation, and propose a two-stage seeding model with the FP embedded, where neighbors are seeded. On this basis, for comparison we formulate the non-adaptive case and adaptive case, both proven to be NP-hard. In the non-adaptive case, discounts are allocated to users all at once. We show the monotonicity of influence spread w.r.t. discount allocation and design a two-stage coordinate descent framework to decide the discount allocation. In the adaptive case, users are sequentially seeded based on observations of existing seeding and diffusion results. We prove the adaptive submodularity and submodularity of the influence spread function in two stages. Then, a series of adaptive greedy algorithms are proposed with constant approximation ratio.

VASOS ATIPICOS (FIO DE PRATA-LIKE) E CORIORRETINITE EM PACIENTE ASSINTOMATICA: RELATO DE CASO

Introdução

A toxoplasmose é uma doença infecto-parasitária que afeta até um terço da população global. A infecção ocular é uma manifestação comum, tratando-se da principal causa de uveíte posterior infecciosa em nosso meio. A lesão característica é a retinocoroidite focal, unilateral, granulomatosa e exsudativa com presença de IgG circulantes. Os vasos retinianos podem apresentar perivasculite.Na retina, os vasos em “fio de prata” são vasos com reflexo arteriolar alterado, que não apresentam a coluna sanguínea vermelha, seja por espessamento, hialinização ou redução do lúmen. Tal alteração está associada à fase esclerosante da retinopatia hipertensiva.Esse relato expõe a presença desse sinal não convencional identificado nos vasos maculares da retina em paciente IgG + para toxoplasmose, enfatizando a hipótese de conexão entre a doença e essa alteração estrutural.

Métodos

Este é um relato de caso observacional e descritivo. Os dados foram obtidos por acompanhamento ambulatorial no Instituto da Visão do Espírito Santo - IVES.

Resultados

Mulher, 52 anos, sem queixas oftalmológicas. Acuidade visual sem correção (AVsc) 20/20 em ambos os olhos (AO). Pressão intraocular (PIO) de 18 mmHg em AO. À fundoscopia (FO), escavação fisiológica em nervo óptico (NO) em AO, leve palidez temporal em olho direito (OD). Sem alterações à biomicroscopia (BIO). Retinografia revelou alterações cicatriciais periféricas próximas à artéria temporal superior e presença de vasos em fio de prata-like a nível de mácula em OD. Suspeitou-se de doença falciforme ou outras doenças sistêmicas, descartadas por exames, e outras entidades infecciosas (LUES, Tuberculose, HIV, CMV – todos negativos). Sorologia para toxoplasmose IgM - e IgG +. Realizada angiofluoresceinografia (AGF) que revelou defeito em janela e bloqueio na lesão temporal superior, sugerindo coriorretinite em OD e alterações inespecíficas em OE. Orientou-se retorno anual para acompanhamento de retina.

Conclusões

Os vasos em fio de prata geralmente estão relacionados à retinopatia hipertensiva. O caso apresentado difere do esperado pois a paciente não é hipertensa, nem possui qualquer doença sistêmica. Deve-se ressaltar a sorologia IgG positiva para toxoplasmose como indicativo de possível agente da alteração do reflexo arteriolar, por se tratar da principal causa uveíte posterior em nosso meio. Desse modo, destaca-se a importância de reconhecer essa forma de apresentação e elencá-la como possibilidade para investigação em casos similares.

Theory of nuclear magnetic relaxation in Haldane gap materials: an illustration of the use of (1+1)-dimensional field theory techniques
Creators: name: Sagi, Jacob S.
Publisher: name: University of British Columbia
Year: 2009

description: A comprehensive theory of nuclear magnetic relaxation in S = 1 Haldane gap materials is developed using nonlinear-σ, boson and fermion models. We find that at temperatures much smaller than the lowest gap the dominant contribution to the relaxation rate comes from two magnon processes with T₁⁻¹ ∼ e[sup -Δm/T], where Δm is the smallest gap corresponding to a polarization direction perpendicular to the field direction. As the gap closes, we find that the dominant contribution comes from one magnon processes, and the result depends on the symmetry of the Hamiltonian. Overall the models agree qualitatively, except near the critical regime, where the fermion model is shown to be the best description. We include a thorough discussion of the effects of interchain-couplings, nearest neighbour hyperfine interactions and crystal structure, and introduce a new theory of impurities corresponding to broken chain ends weakly coupled to bulk magnons. The work is then applied to recent measurements on NENP. We find overall fair agreement between available T₁⁻¹ data and our calculations. We finish by suggesting further experimental tests of our conclusions.

Our major results are in the following: (1) The power-law component of the X-ray luminosities, in the energy range from 0.5 keV to 8 keV, of the nebulae and of the pulsar both show a strong correlation with the pulsar spin-down power ($\dot{E}$), consistent with earlier studies. However, equally significant correlations with the magnetic field strength at the light cylinder ($B_{\rm lc}$) are also found. The similar significance level of the correlations with $\dot{E}$ and with $B_{\rm lc}$ suggests that not only $\dot{E}$ but also $B_{\rm lc}$ plays an important role in understanding these power-law emissions. (2) Thermal X-ray emissions are detected in 12 pulsars among the 35 samples. With derived temperature as one additional variable, we found that the photon indices of pulsar's non-thermal X-ray power-law spectra can be well described by a linear function of $\log P$, $\log\dot{P}$ and temperature logarithm $\log T$. It indicates that the surface temperature of neutron stars plays an important role in determining the energy distribution of the radiating pair plasma in pulsar's magnetospheres.

description: String theoretical arguments led to the hypothesis that the ratio of viscosity to entropy of any physical system has a lower bound. Strongly coupled systems usually have a small viscosity compared to weakly coupled plasmas in which the viscosity is proportional to the mean free path. In the case of a one-component plasma the viscosity as a function of the coupling strength shows a minimum. Here we show that the ratio of viscosity to entropy of a strongly coupled one-component plasma is always above the lower bound predicted by string theory.

A study of ergodicity and chaos in the Bianchi cosmologies
Creators: name: Bhushan, Vikas
Publisher: name: University of British Columbia
Year: 2009

description: The flow on the phase space of gravitational degrees of freedom for the spatially homogeneous Bianchi I cosmology is studied in detail. Problems associated with analyzing the dynamics numerically are discussed and a rigorous analysis of the phase space dynamics for Bianchi I is presented. The global topology of the phase space is shown to be nontrivial and to have an important effect on the dynamics of the system. Although this results in complicated dynamics on the phase space, which is contrary to what has previously been thought, the system is nevertheless shown to be non-ergodic. Implications for the study of the dynamics of other Bianchi models is discussed.

Classification of atomic environments via the Gromov-Wasserstein distance

description: Interpreting molecular dynamics simulations usually involves automated classification of local atomic environments to identify regions of interest. Existing approaches are generally limited to a small number of reference structures and only include limited information about the local chemical composition. This work proposes to use a variant of the Gromov-Wasserstein (GW) distance to quantify the difference between a local atomic environment and a set of arbitrary reference environments in a way that is sensitive to atomic displacements, missing atoms, and differences in chemical composition. This involves describing a local atomic environment as a finite metric measure space, which has the additional advantages of not requiring the local environment to be centered on an atom and of not making any assumptions about the material class. Numerical examples illustrate the efficacy and versatility of the algorithm.

description: In this paper, we study a free boundary problem for compressible spherically symmetric Navier-Stokes equations without a solid core. Under certain assumptions imposed on the initial data, we obtain the global existence and uniqueness of the weak solution, give some uniform bounds (with respect to time) of the solution and show that it converges to a stationary one as time tends to infinity. Moreover, we obtain the stabilization rate estimates of exponential type in $L^\infty$-norm and weighted $H^1$-norm of the solution by constructing some Lyapunov functionals. The results show that such system is stable under the small perturbations, and could be applied to the astrophysics.

description: Η μελέτη των απολιθωμάτων Πλειο-Πλειστοκαινικών προβοσκιδωτών από τις Συλλογές του Μουσείου Γεωλογίας και Παλαιοντολογίας Α.Π.Θ. έδειξε την ύπαρξη στην Βόρειο Ελλάδα σχεδόν όλων των ειδών Mammuthus που συναντούνται στον Ευρωπαϊκό χώρο καθώς και του είδους Elephas (Palaeoloxodon) antiquus. Το υλικό που μελετήθηκε προέρχεται από άγνωστους στρωματογραφικούς ορίζοντες και για το λόγο αυτό έγινε μία προσπάθεια ένταξής του σε ένα χρονολογικό φάσμα σύμφωνο με τη στρωματογραφία των περιοχών εύρεσης. Για πρώτη φορά προσδιορίζεται στον ελληνικό χώρο το είδος Mammuthus rumanus. To είδος αυτό τοποθετείται πιθανότατα στους κατώτερους Πλειο-Πλειστοκαινικούς στρωματογραφικούς ορίζοντες της περιοχής Τσοτυλίου και Πτολεμαϊδας, στους οποίους αποδίδεται μία ηλικία ≤ 3.4 Μa. Με την παρούσα εργασία αποδεικνύεται η αφθονία των προβοσκιδωτών στις Πλειστοκαινικές λεκάνες της Βορείου Ελλάδος. Η μελέτη αυτών μπορεί να βοηθήσει ουσιαστικά στην διερεύνηση της εξέλιξης των Πλειστοκαινικών Προβοσκιδωτών της Ευρώπης και της βιοστρωματογραφικής τους εξάπλωσης.
description: The study of fossil Plio-Pleistocene proboscidea in the collections of the Museum of Geology and Paleontology, Department of Geology A.U.T.H. showed the presence in Northern Greece of almost all European species of Mammuthus, as well as of the straight tusk elephant Elephas (Palaeoloxodon) antiquus. The studied material comes from unknown stratigraphic horizons and for this reason an attempt to frame chronologically the specimens was undertaken based on local stratigraphic data. The study reveals the presence of the primitive Mammuthus rumanus for the first time in Greece. This species found in the lower stratigraphic horizons of Tsotyli and Ptolemais areas, is dated to approximately ≤ 3.4 Ma. The wealth record of Pleistocene Proboscidea in the basins of Northern Greece suggests that their study would greatly contribute to a better understanding of their evolution and their European spatiotemporal radiation.

description: In this paper, a secure communication model for cognitive multi-user massive multiple-input multiple-output (MIMO) systems with underlay spectrum sharing is investigated. A secondary (cognitive) multi-user massive MIMO system is operated by using underlay spectrum sharing within a primary (licensed) multi-user massive MIMO system. A passive multi-antenna eavesdropper is assumed to be eavesdropping upon either the primary or secondary confidential transmissions. To this end, a physical layer security strategy is provisioned for the primary and secondary transmissions via artificial noise (AN) generation at the primary base-station (PBS) and zero-forcing precoders. Specifically, the precoders are constructed by using the channel estimates with pilot contamination. In order to degrade the interception of confidential transmissions at the eavesdropper, the AN sequences are transmitted at the PBS by exploiting the excess degrees-of-freedom offered by its massive antenna array and by using random AN shaping matrices. The channel estimates at the PBS and secondary base-station (SBS) are obtained by using non-orthogonal pilot sequences transmitted by the primary user nodes (PUs) and secondary user nodes (SUs), respectively. Hence, these channel estimates are affected by intra-cell pilot contamination. In this context, the detrimental effects of intra-cell pilot contamination and channel estimation errors for physical layer secure communication are investigated. For this system set-up, the average and asymptotic achievable secrecy rate expressions are derived in closed-form. Specifically, these performance metrics are studied for imperfect channel state information (CSI) and for perfect CSI, and thereby, the secrecy rate degradation due to inaccurate channel knowledge and intra-cell pilot contamination is quantified. Our analysis reveals that a physical layer secure communication can be provisioned for both primary and secondary massive MIMO systems even with the channel estimation errors and pilot contamination.

description: We investigate the pure annihilation type radiative $B$ meson decays $B^0 \to ϕγ$ and $B_s \to ρ^0(ω)γ$ in the soft-collinear effective theory. We consider three types of contributions to the decay amplitudes, including the direct annihilation topology, the contribution from the electro-magnetic penguin operator and the contribution of the neutral vector meson mixings. The numerical analysis shows that the decay amplitudes are dominated by the $ω-ϕ$ mixing effect in the $B^0 \to ϕγ$ and $B_s \to ωγ$ modes. The corresponding decay branching ratios are enhanced about three orders of magnitudes relative to the pure annihilation type contribution in these two decay channels. The decay rate of $B_s \to ρ^0γ$ is much smaller than that of $B_s \to ωγ$ because of the smaller $ρ^0-ϕ$ mixing. The predicted branching ratios $B(B^{0}\rightarrowϕγ)=(3.99^{+1.67}_{-1.46} )\times10^{-9},\,B(B_s\rightarrowωγ)=(2.01^{+0.81}_{-0.71} )\times10^{-7}$ are to be tested by the Belle-II and LHC-b experiments.

description: We report a study of the rotational dynamics in double-walled nanotubes using molecular dynamics simulations and a simple analytical model reproducing very well the observations. We show that the dynamic friction is linear in the angular velocity for a wide range of values. The molecular dynamics simulations show that for large enough systems the relaxation time takes a constant value depending only on the interlayer spacing and temperature. Moreover, the friction force increases linearly with contact area, and the relaxation time decreases with the temperature with a power law of exponent $-1.53 \pm 0.04$.

description: With every Eo-semigroup (acting on the algebra of of bounded operators on a separable infinite-dimensional Hilbert space) there is an associated Arveson system. One of the most important results about Arveson systems is that every Arveson system is the one associated with an Eo-semigroup. In these notes we give a new proof of this result that is considerably simpler than the existing ones and allows for a generalization to product systems of Hilbert module (to be published elsewhere).
