description: Within a pQCD inspired kinetic parton cascade we simulate the space time evolution of gluons which are produced initially in a heavy ion collision at RHIC energy. The inelastic gluonic interactions $gg \leftrightarrow ggg$ do play an important role: For various initial conditions it is found that thermalization and the close to ideal fluid dynamical behaviour sets in at very early times. Special emphasis is put on color glass condensate initial conditions and the `bottom up thermalization' scenario. Off-equilibrium $3\to 2$ processes make up the very beginning of the evolution leading to an initial decrease in gluon number and a temporary avalanche of the gluon momentum distribution to higher transversal momenta.

description: Presentation at the Wind Energy Science Conference in Cork, Ireland. The "Wakebench" framework for the evaluation of wind farm flow models is presented. This IEA-Wind Task gathers an international forum of researchers to define best practices for model evaluation through model intercomparison benchmarks. The modeling scope spans multi-scale models dealing with the atmospheric boundary layer, to predict wind conditions for site suitability assessment and numerical site calibration, as well as wind farm wake effects for the assessment of array efficiency and loads in connection to wind farm design. An overview of current activities is presented.

description: We study the chiral phase transition inside a rotating cylinder within the framework of the Namb--Jona-Lasinio model. A spectral boundary condition is imposed to avoid faster than light. We investigate how the geometry of the cylinder and rotation influence the chiral phase transition at finite temperature and chemical potential. The inhomogeneous effects caused by the finite size and rotation are also taken into account. It is found that finite size will reduce the chiral transition temperature and raises the chiral transition chemical potential, while the rotation reduces both the chiral transition temperature and chemical potential. In addition, we discuss the implications of our results in heavy-ion collisions and equation of states of neutron star.

description: Τα L-συστήματα αποτελούν έναν μαθηματικό φορμαλισμό που προτάθηκε από το βιολόγο Aristid Lindermayer το 1968 ως θεμέλιο για μια αξιωματική θεωρία της βιολογικής ανάπτυξης. Πρόσφατα, τα L-συστήματα έχουν βρει πολλές εφαρμογές σε γραφικά υπολογιστών (Smith, 1987; Prusinkiewicz and Lindenmayer, 1990). Δύο κύριοι τομείς περιλαμβάνουν την παραγωγή fractals και την μοντελοποίηση της ανάπτυξης των φυτών. Κεντρικής σημασίας για τα L-συστήματα, είναι η έννοια της επανεγγραφής, όπου η βασική ιδέα είναι να ορίσει πολύπλοκα αντικείμενα με διαδοχική αντικατάσταση τμημάτων ενός απλού αντικειμένου, χρησιμοποιώντας ένα σύνολο κανόνων επανεγγραφής ή παραγωγές. Η επανεγγραφή πραγματοποιείται κατ’ επανάληψη. Συστήματα επανεγγραφής που έχουν μελετηθεί εκτεταμένα είναι αυτά που λειτουργούν πάνω σε αλυσίδες χαρακτήρων. Ο Aristid Lindermayer εισήγαγε ένα νέου τύπου μηχανισμό επανεγγραφής συμβολοσειρών, που στη συνέχεια ονομάστηκαν L-συστήματα. Η ουσιώδης διαφορά μεταξύ των πλέον γνωστών γραμματικών Chomsky και των L-συστημάτων έγκειται στη μέθοδο εφαρμογής των κανόνων επανεγγραφής. Στις Chomsky γραμματικές οι παραγωγές εφαρμόζονται διαδοχικά, ενώ στα L-συστήματα εφαρμόζονται παράλληλα, αντικαθιστώντας ταυτόχρονα όλα τα γράμματα σε μια δεδομένη λέξη. Αυτή η διαφορά αντικατοπτρίζει το βιολογικό κίνητρο των L-συστημάτων. Οι παραγωγές προορίζονται να συλλάβουν κυτταρικές διαιρέσεις σε πολυκύτταρους οργανισμούς, όπου πολλές διαιρέσεις μπορεί να συμβαίνουν ταυτόχρονα.
description: L-systems are a mathematical formalism proposed by the biologist Aristid Lindenmayer in 1968 as a foundation for an axiomatic theory of biological development. More recently, L-systems found several applications in computer graphics (Smith, 1987; Prusinkiewicz and Lindenmayer, 1990). Two principal areas include generation of fractals and realistic modeling of plants. Central to L-systems, is the notion of rewriting, where the basic idea is to define complex objects by successively replacing parts of a simple object using a set of rewriting rules or productions. The rewriting can be carried out recursively. The most extensively studied and the best understood rewriting systems operate on character strings. Aristid Lindenmayer’s work introduced a new type of string rewriting mechanism, subsequently termed L-systems. The essential difference between the most known Chomsky grammars and L-systems lies in the method of applying productions. In Chomsky grammars productions are applied sequentially, whereas in L-systems they are applied in parallel, replacing simultaneously all letters in a given word. This difference reflects the biological motivation of L-systems. Productions are intended to capture cell divisions in multicellular organisms, where many divisions may occur at the same time.

description: We give a classification of irreducible metabelian representations from a knot group into SL(n,C) and GL(n,C). If the homology of the n-fold branched cover of the knot is finite, we show that every irreducible metabelian SL(n,C) representation is conjugate to a unitary representation and that the set of conjugacy classes of such representations is finite. In that case, we give a formula for this number in terms of the Alexander polynomial of the knot. These results are the higher rank generalizations of a result of Nagasato, who recently studied irreducible, metabelian SL(2,C) representations of knot groups. Finally we deduce the existence irreducible metabelian SL(n,C) representations of the knot group for any knot with nontrivial Alexander polynomial.

Πρόκειται για δύο καλαίσθητα «μικρά περιοδικά». Το Οκτασέλιδο ήταν αρχικά τριμηνιαίο και αργότερα διμηνιαίο περιοδικό οκτώ σελίδων που ανθολόγησε ποιήματα και πεζά κείμενα ενός κυρίως συγγραφέα ή έργα ενός καλλιτέχνη. Το Μπιλιέτο υπήρξε εξαμηνιαίο εκτός από ένα τεύχος που ήταν ετήσιο. Στις σελίδες του φιλοξενήθηκαν ποιητικά, πεζά, θεατρικά και θεολογικά κείμενα, πρωτότυπα και μεταφρασμένα. Επίσης δοκίμια και μελέτες, κριτικές βιβλίων αλλά και έργα γλυπτικής και ζωγραφικής καθώς και φωτογραφικό υλικό. Ο ρεαλισμός, η βιωματικότητα και το έντονα ερωτικό στοιχείο χαρακτηρίζουν την ύλη των δύο περιοδικών που αποτελούν συνέχεια προγενέστερών τους, όπως το 3ο Μάτι, ο Κοχλίας και κυρίως η Διαγώνιος.

description: Octaselido (1994-2013) and Mpilieto (2001-2008) are two literary periodicals edited in Paiania by the poet and editor Basilis Dimitrakos. Both are elegant "little magazines". Octaselido began as a quarterly review and later became a bimonthly eight-page magazine which published anthologies of poetry and prose mainly of a single author or works of one artist. Mpilieto was a magazine published every semester except for one issue which was annual. It hosted poetry, prose, plays and theological texts, in the original language and translations. Essays and studies, book reviews, works of art such as sculptures and paintings as well as photographs were also contained within. Realism and an intensely erotic element characterize the material of the two magazines. Octaselido and Mpilieto follow the literary tradition of magazines like 3ο Mati, Kochlias and Diagonios. The style, the character, the content and the structure of Octaselido and Mpilieto are distinguished by the analytical presentation of the contents, of the individuals mentioned and of the different issues dealt with.

description: We propose a two-dimensional electron gas (2DEG) system in which an external magnetic (B) field with a small chirality is applied to provide a topological U(1) U(1) gauge field that separates conduction electrons of opposite spins in the transverse direction. Additionally, the vertical electric (E) field in the 2DEG, together with spin-orbit coupling, produces a SU(2) gauge field which reinforces / opposes the effect of the topological gauge. The system thus provides a tunable spin Hall effect, where an applied gate voltage on the 2DEG can be used to modulate the transverse spin current. As this method leads to the enhancement or cancellation of intrinsic spin Hall, it naturally distinguishes the extrinsic from the intrinsic effect.

description: The gas equation of state may be one of the critical factors for the disk instability theory of gas giant planet formation. This letter addresses the treatment of H$_2$ in hydrodynamical simulations of gravitationally unstable disks. In our discussion, we point out possible consequences of erroneous specific internal energy relations, approximate specific internal energy relations with discontinuities, and assumptions of constant $Γ_1$. In addition, we consider whether the ortho/para ratio for H$_2$ in protoplanetary disks should be treated dynamically as if the species are in equilibrium. Preliminary simulations indicate that the correct treatment is particularly critical for the study of gravitational instability when $T = 30$-50 K.

description: The ability to engineer the interactions in assemblies of nanoscale magnets is central to the development of artificial spin systems and spintronic technologies. Following the emergence of the Dzyaloshinskii-Moriya interaction (DMI) in thin film magnetism, new routes have been opened to couple the nanomagnets via strong chiral interactions, which is complementary to the established dipolar and exchange coupling mechanisms. In this Perspective, we review recent progress in the engineering of synthetic magnets coupled by the interlayer and intralayer DMI. We show how multilayer chiral magnetic structures and two-dimensional synthetic antiferromagnets, skyrmions, and artificial spin systems can be realized by simultaneous control of the DMI and magnetic anisotropy. In addition, we show that, with the combination of DMI and current-induced spin-orbit torques, field-free switching of synthetic magnetic elements is obtained as well as all-electric domain wall logic circuits.

The Optics of Language-Integrated Query

Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: Monadic comprehensions reign over the realm of language-integrated query (LINQ), and for good reasons. Indeed, comprehensions are tightly integrated with general purpose programming languages and close enough to common query languages, such as SQL, to guarantee their translation into effective queries. Comprehensions also support features for writing reusable and composable queries, such as the handling of nested data and the use of functional abstractions. In parallel to these developments, optics have emerged in recent years as the technology of choice to write programs that manipulate complex data structures with nested components. Optic abstractions are easily composable and, in principle, permit both data access and updates. This paper attempts to exploit the notion of optic for LINQ as a higher-level language that complements comprehension-based approaches. In order to do this, we lift a restricted subset of optics, namely getters, affine folds and folds, into a full-blown DSL. The type system of the resulting language of optics, that we have named Optica, distills their compositional properties, whereas its denotational semantics is given by standard optics. This formal specification of the concept of optic enables the definition of non-standard optic representations beyond van Laarhoven, profunctor optics, etc. In particular, the paper demonstrates that a restricted subset of XQuery can be understood as an optic representation; it introduces Triplets, a non-standard semantic domain to normalize optic expressions and facilitate the generation of SQL queries; and it describes how to generate comprehension-based queries from optic expressions, thus showing that both approaches can coexist.The paper also describes S-Optica, a Scala implementation of Optica using the tagless-final approach.

description: In this paper, we are concerned with the hydrodynamic limit to rarefaction waves of the compressible Euler system for the Landau equation with Coulomb potentials as the Knudsen number $ε>0$ is vanishing. Precisely, whenever $ε>0$ is small, for the Cauchy problem on the Landau equation with suitable initial data involving a scaling parameter $a\in [\frac{2}{3},1]$, we construct the unique global-in-time uniform-in-$ε$ solution around a local Maxwellian whose fluid quantities are the rarefaction wave of the corresponding Euler system. In the meantime, we establish the convergence of solutions to the Riemann rarefaction wave uniformly away from $t=0$ at a rate $ε^{\frac{3}{5}-\frac{2}{5}a}|\ln ε|$ as $ε\to 0$. The proof is based on the refined energy approach combining [19] and [32] under the scaling transformation $(t,x)\to (ε^{-a}t,ε^{-a}x)$.

Application of diffractive optical elements in confocal microscopy
Creators: name: Li, Zheng
Publisher: name: Karlsruhe
Year: 2019

description: In traditional confocal microscopy, there is a tradeoff between the spatial resolution and the field of view due to the limitations of the objective lenses. To solve this problem, diffractive optical elements (DOEs) are used to generate illumination spots with high NA in a large area simultaneously. However, such DOEs in current research are only used as illuminators. In this work, the idea of superposition is utilized in DOEs to have flexible functionality and replace high-NA objectives for confocal measurement. To design the DOEs, different numerical simulation methods for light propagation are investigated and compared. Rayleigh-Sommerfeld integral is chosen to simulate the DOEs to get accurate results. Two kinds of DOEs are designed and simulated for 3D confocal surface measurements.

description: The aim of the present thesis was the study of cultural and social planning for the reactivation of urban open spaces. I examined the terms of urban cultural landscapes, of cultural geography and of cultural economy. Then, I analyzed different forms of cultural and social policy applied to urban landscape architectural design and I described a series of examples and their relation with the cultural and social led urban regenerations respectively. The theoretical background defined the methodology of cultural and social reactivation of urban open spaces. Furthermore, this methodology, was applied to the West Wall of Thessaloniki, aiming at the cultural stimulation of the area through the social engagement of all social groups that co-exist in the surrounding area. The study was completed through landscape architectural plans, which included all key-terms transformed into spatial proposals.

Low Mach number modeling of Type I X-ray burst deflagrations

description: The Low Mach Number Approximation (LMNA) is applied to 2D hydrodynamical modeling of Type I X-ray bursts on a rectangular patch on the surface of a non-rotating neutron star. Because such phenomena involve decidedly subsonic flows, the timestep increase offered by the LMNA makes routine simulations of these deflagrations feasible in an environment where strong gravity produces significant stratification, while allowing for potentially significant lateral differences in temperature and density. The model is employed to simulate the heating, peak, and initial cooling stages in the deep envelope layers of a burst. During the deflagration, Benard-like cells naturally fill up a vertically expanding convective layer. The Mach number is always less than 0.15 throughout the simulation, thus justifying the low Mach number approximation. While the convective layer is superadiabatic on average, significant fluctuations in adiabaticity occur within it on subconvective timescales. Due to convective layer expansion, significant compositional mixing naturally occurs, but tracer particle penetration through the convective layer boundaries on convective timescales is temporary and spatially limited. Thus, mixing occurs on the relatively slow burst timescale through thermal expansion of the convective layer rather than from mass penetration of the convective layer boundary through particle convection. At the convective layer boundaries where mixing is less efficient, the actual temperature gradient more closely follows the Ledoux criteria.

description: Aim of this thesis is the investigation of different ways in order to achieve sustainability in urban context. The issues of sustainability, sustainable growth will also be analyzed as well as the notion of urban sustainability and sustainable cities. The parameters that form the frame of sustainable programming will be presented in the course of the analysis, followed by those of sustainable design in urban context. These parameters will be sought within the broad range of sciences that work together in the field of sustainability. The notion of sustainability indicators wills to succeed programming, aiming to quantify sustainability and to convert it to a measurable size. Among a vast selection of indicators that deal strictly with sustainability, the SITES rating system will be chosen because of its proximity with the practice of landscape architecture. The application of these parameters, methods and practices of urban sustainability will be examined through projects that form some of the most up-to-date expressions of urban and landscape sustainability.

Human Fetal Tissue

description: Parkinson disease (PD) is characterized by a loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The selective loss of this cell population makes PD a good candidate for cell-based therapies. Clinical trials using cells derived from human fetal ventral midbrain (hVM) have shown that dopamine release was restored to normal levels and in some PD patients produced substantial long-term clinical improvement. Although new sources of cells such as human embryonic stem cells (hESCs) and pluripotent stem cells (IPCs) are now been the focus of studies and new clinical trials, the hVM tissue represent the gold standard for cell based therapies and serve as important comparator for new cell sources. Therefore there is a need of an increased understanding and characterization of this tissue with new technologies such as organoid culture conditions and single cell sequencing. This study is designed to give a detailed characterization of human fetal VM tissue in standard culture conditions (2D) versus organoids (3D). We used immunocytochemistry to study the presence of ventral midbrain markers in 2D versus 3D condition together with single cell RNA sequencing to transcriptionally compare fetal VM tissue in standard or organoid cultures. Our analysis confirmed that the 3D condition preserve the neuronal composition of the tissue more than standard culture where instead, over a long period of time, the majority of the cells are non-neuronal. This suggest that 3D culture represent a better condition to maintain and study dopaminergic neurons in culture.

description: We investigate the ballistic motion of electrons and holes in III-V semiconductor quantum wells with spin-orbit coupling and a homogeneous in-plane electric field. As a result of a non-perturbative treatment of both of these influences, particle wave packets undergo a pronounced side jump perpendicular to the field direction. For wave packets of sufficient width the amplitude of this motion can be estimated analytically and increases with decreasing field strength. We discuss the scaling behavior of the effect and some if its experimental implications

description: The amplitudes of the transition gamma* N -> P11(1440) are calculated within light-front relativistic quark model assuming that the P11(1440) is the first radial excitation of the 3q ground state. The results are presented along with the predictions obtained in other relativistic quark models. In comparison with the previous calculations, we have extended the range of Q^2 up to 4.5 GeV^2 to cover the kinematic interval of the forthcoming experimental data. Using approach based on PCAC, we have checked the relative sign between quark model predictions for the N and P11(1440) contributions to the pion electroproduction found in previous investigations.

description: The X-ray binary 4U 1954+31 has been classified as a Low Mass X-ray Binary (LMXB) containing a M giant and a neutron star (NS). It has also been included in the rare class of X-ray symbiotic binaries (SyXB). The Gaia parallax, infrared colors, spectral type, abundances, and orbital properties of the M star demonstrate that the cool star in this system is not a low mass giant but a high mass M supergiant. Thus, 4U 1954+31 is a High Mass X-ray Binary (HMXB) containing a late-type supergiant. It is the only known binary system of this type. The mass of the M I is 9$^{+6}_{-2}$ M$_\odot$ giving an age of this system in the range 12 - 50 Myr with the NS no more than 43 Myr old. The spin period of the NS is one of the longest known, 5 hours. The existence of M I plus NS binary systems is in accord with stellar evolution theory, with this system a more evolved member of the HMXB population.

Σε μια χρονική περίοδο όπου ξεκινά η ελληνιστική εποχη (323 – 31 π.Χ.) . Προκειμένου να μπορέσουμε να παρουσιάσουμε μια ολοκληρωμένη εικόνα της κατάστασης και να επισημάνουμε τις αλλαγές που προέκυψαν στην εποχή που εξετάζουμε πρέπει να ορίσουμε ένα σημείο αναφοράς, το οποίο θα λειτουργήσει ως οδηγός στην πορεία της εργασίας. Αυτό το σημείο αναφοράς είναι η πολιτική προσωπικότητα του Λυκούργου (390 π.Χ.-324 π.Χ.), όπως αυτή παρουσιάζεται τόσο μέσα από το πολιτικό του έργο όσο και μέσα από πηγές που διασωζονται μέχρι τις μέρες μας.
description: This dissertation aims to analyse the religious and economic situation in Athens during the 4th century BC In this period of time, the Hellenistic period begins(323-31 BC). In order to be able to present in whole the situation and to give prominence to the various changes that have occurred in this timespan, we have to define a reference point which will serve as a directional guide of this essay. This reference point will be the political figure of Lycurgus (390 BC-324 BC), presented both through his political work and variant sources that have survived until this day.

description: We have previously proposed a light pseudoscalar Higgs boson in the next-to-minimal supersymmetric standard model (NMSSM), the A_1^0, as a candidate to explain the HyperCP observations in Sigma^+ -> p mu^+ mu^-. In this paper we calculate the rates for several other rare decay modes that can help confirm or refute this hypothesis. The first modes we evaluate are K_L -> pi pi A_1^0, which are interesting because they are under study by the KTeV Collaboration. We next turn to eta -> pi pi A_1^0, which are interesting because they are independent of the details of the flavor-changing sector of the NMSSM and may be accessible at DAPhNE. For completeness, we also evaluate Omega^- -> Xi^- A_1^0.

T.’s lifeworld and language
Creators: name: Johnson, Larry Colvin
Publisher: name: University of British Columbia
Year: 2009

description: During his twelve years of life, T., a gifted boy who was born with severe cerebral palsy, achieved the ability to communicate with "the rest of the world" at an advanced level, though he used facilitated and augmentative communication. The author of this narrative and interpretive study is T.'s father, who maintained a unique dialogue with his son. T. himself volunteered to contribute actively to the study by helping to plan and to edit, and by supplying a number of autobiographical sketches. The pedagogical relationship that existed between T. and his father is prominently featured. The study explores T.'s individual case through thirteen narrative "scenes" (beginning with his birth and ending with his twelfth year), which address various particulars of his lifeworld and his language development. Each narrative scene is followed by two, three, or four interpretive passages, each of which interprets one of seven themes that emerged from T.'s life. The seven themes are: memory, observation, scientific/technological assessment, not foreclosing on the future, integration, communication, and growth. The interpretive passages treat the seven themes at four levels of interpretation: the literal level, the moral level, the allegorical level, and the anagogic level. The attempt is to revive an exegetic practice common in the days before the Enlightenment, Cartesian doubt, and the "mathematical project" (Heidegger, 1993c, p. 293). Following the dictum that "the hermeneutic imagination is not limited in its conceptual resources to the texts of the hermeneutic tradition itself" (Smith, 1991, p. 201), the study borrows from a variety of sources, including Astrology, Waldorf education, and Zen. The reader is offered a direct experience of "the fecundity of the individual case" (Gadamer, cited in Jardine, 1994, p. 143). Emerging, through the thirteen scenes, the seven themes, and the four levels of interpretation, is a unique picture of an exceptional boy's language development.

description: We study Class-I excitable $1$-dimensional media showing the appearance of propagating traveling pulses. We consider a general model exhibiting Class-I excitability mediated by two different scenarios: a homoclinic (saddle-loop) and a SNIC (Saddle-Node on the Invariant Circle) bifurcations. The distinct properties of Class-I with respect to Class-II excitability infer unique properties to traveling pulses in Class-I excitable media. We show how the pulse shape inherit the infinite period of the homoclinic and SNIC bifurcations at threshold, exhibiting scaling behaviors in the spatial thickness of the pulses that are equivalent to the scaling behaviors of characteristic times in the temporal case.

Little Higgs models with a light T quark

description: We study Little Higgs models based on a SU(3)_1 x SU(3)_2 global symmetry and with two scales (the two vacuum expectation values f_{1,2}) substantially different. We show that all the extra vector boson fields present in these models may be much heavier than the vectorlike T quark necessary to cancel top-quark quadratic corrections. In this case the models become an extension of the standard model with a light (500 GeV) T quark and a scalar Higgs field with a large singlet component. We obtain that the Yukawa and the gauge couplings of the Higgs are smaller than in the standard model, a fact that reduces significantly the Higgs production rate through glu-glu and WW fusion. The T-quark decay into Higgs boson becomes then a dominant Higgs production channel in hadron colliders.

description: Abstract

Functional magnetic resonance imaging (fMRI) has significantly transformed neurosurgical practice by enabling real-time visualization of brain activity. Developed in the early 1990s, fMRI surpassed traditional imaging techniques like CT and MRI, which could only capture static brain structures. fMRI’s ability to detect blood-oxygen-level-dependent (BOLD) signals in response to neuronal activity revolutionized brain mapping, allowing for non-invasive localization of functional areas essential for speech, movement, and cognition. Neurosurgeons now use fMRI extensively in pre-surgical planning, particularly in cases involving tumors near critical brain regions. This precise mapping has reduced post-surgical impairments by facilitating targeted tumor resections while preserving essential functions. Additionally, advancements in integrating fMRI with diffusion tensor imaging (DTI) and tractography have further refined brain connectivity mapping, enhancing surgical outcomes. Despite challenges, including variability in patient-specific results and inherent risks, fMRI remains indispensable. Ongoing developments in AI and hardware improvements promise to elevate fMRI’s role in neurosurgery.

Jeans mass-radius relation of self-gravitating Bose-Einstein condensates and typical parameters of the dark matter particle

description: We study the Jeans mass-radius relation of Bose-Einstein condensate dark matter in Newtonian gravity. We show at a general level that it is similar to the mass-radius relation of Bose-Einstein condensate dark matter halos [P.H. Chavanis, Phys. Rev. D {\bf 84}, 043531 (2011)]. Bosons with a repulsive self-interaction generically evolve from the Thomas-Fermi regime to the noninteracting regime as the Universe expands. In the Thomas-Fermi regime, the Jeans radius remains approximately constant while the Jeans mass decreases. In the noninteracting regime, the Jeans radius increases while the Jeans mass decreases. Bosons with an attractive self-interaction generically evolve from the nongravitational regime to the noninteracting regime as the Universe expands. In the nongravitational regime, the Jeans radius and the Jeans mass increase. In the noninteracting regime, the Jeans radius increases while the Jeans mass decreases. The transition occurs at a maximum Jeans mass which is similar to the maximum mass of Bose-Einstein condensate dark matter halos with an attractive self-interaction. We use the mass-radius relation of dark matter halos and the observational evidence of a ``minimum halo'' (with typical radius $R\sim 1\, {\rm kpc}$ and typical mass $M\sim 10^8\, M_{\odot}$) to constrain the mass $m$ and the scattering length $a_s$ of the dark matter particle.

description: Financial markets are event- and data-driven to an extremely high degree. For making decisions and triggering actions stakeholders require notifications about significant events and reliable background information that meet their individual requirements in terms of timeliness, accuracy, and completeness. As one of Europe's leading providers of financial data and regulatory solutions vwd processes an average of 18 billion event notifications from 500+ data sources for 30 million symbols per day. Our large-scale distributed event-based systems handle daily peak rates of 1+ million event notifications per second and additional load generated by singular pivotal events with global impact. In this poster we give practical insights into our IT systems. We outline the infrastructure we operate and the event-driven architecture we apply at vwd. In particular we showcase the (geo)distributed publish/subscribe broker network we operate across locations and countries to provide market data to our customers with varying quality of information (QoI) properties.
