description: The thermal and fragmentation properties of star-forming clouds have important consequences on the corresponding characteristic stellar mass. The initial composition of the gas within these clouds is a record of the nucleosynthetic products of previous stellar generations. In this paper we present a model for the evolution of star-forming clouds enriched by metals and dust from the first supernovae, resulting from the explosions of metal-free progenitors with masses in the range 12 - 30 Msun and 140 - 260 Msun. Using a self-consistent approach, we show that: (i) metals depleted onto dust grains play a fundamental role, enabling fragmentation to solar or sub-solar mass scales already at metallicities Zcr = 10^{-6} Zsun; (ii) even at metallicities as high as 10^{-2} Zsun, metals diffused in the gas-phase lead to fragment mass scales which are ~ 100 Msun; (iii) C atoms are strongly depleted onto amorphous carbon grains and CO molecules so that CII plays a minor role in gas cooling, leaving OI as the main gas-phase cooling agent in low-metallicity clouds. These conclusions hold independently of the assumed supernova progenitors and suggest that the onset of low-mass star formation is conditioned to the presence of dust in the parent clouds.

Transitioning CMS to Rucio Data Management
Creators: name: Vaandering, Eric
Publisher: name: Zenodo
Year: 2019

description: Following a thorough review in 2018, the CMS experiment at the CERN LHC decided to adopt Rucio as its new data management system. Rucio is emerging as a community software project and will replace an aging CMS-only system before the start-up of LHC Run 3 in 2021. Rucio was chosen after an evaluation determined that Rucio could meet the technical and scale needs of CMS. The data management system for CMS needs to manage the current data sample (approximately 200 PB of data with 1 PB of transfers per day) and have a development path suitable for LHC Run 4 (2026) data rates, which are expected to be 50 times larger. This contribution will detail the ongoing CMS adoption process as we replace our legacy system with Rucio, focusing on the challenges of integrating Rucio into an established set of experimental tools and procedures. This will include the migration of metadata, the construction of interfaces to the rest of the CMS computing tools, scale tests, operations, monitoring, and the plan to gradually turn over primary responsibility for the management of data to Rucio. A description of CMS user data management with Rucio will also be provided.

description: The magnetization reversal process in thin-film ferromagnetic elements with surface anisotropy of various shapes and sizes is investigated by means of numerical simulation. The dependence of the perpendicular and in-plane hysteresis loops on the element thickness and the value of the surface anisotropy constant is obtained. For sufficiently large values of the surface anisotropy constant the magnetization reversal of thin-film elements is shown to occur due to the nucleation of the buckling mode. For an elongated rectangular element the nucleation field of the buckling mode is proportional to the absolute value of the surface anisotropy constant, and inversely proportional to the element thickness.

Exploiting CRIC to streamline the configuration management of glideinWMS factories for CMS support
Creators: name: CMS Collaboration
Publisher: name: Zenodo
Year: 2019

description: GlideinWMS is a workload management and provisioning system that allows sharing computing resources distributed over independent sites. Based on the requests made by glideinWMS Frontends, a dynamically sized pool of resources is created by glideinWMS pilot Factories via pilot job submission to resource sites' computing elements. More than 400 computing elements (CE) are currently serving more than 10 virtual organizations through glideinWMS, with CMS being the biggest user with 230 CEs. The complex configurations of the parameters definining resource requests, as submitted to those CEs, have been historically managed by manually editing a set of different xml files. New possibilities arise with CMS adopting the Computing Resource Information Catalogue (CRIC), an information system that collects, aggregates, stores, and exposes, among other things, computing resource data coming from various data providers. The talk will describe the challenges faced when CMS started to use CRIC to automatically generate the glideinWMS factory configurations. The architecture of the prototype, and the ancillary tools developed to ease this transition, will be discussed. Finally, future plans and milestones will be outlined.

description: The Computing Center of the Institute of Physics (CC FZU) of the Czech Academy of Sciences provides compute and storage capacity to several physics experiments. Most resources are used by two LHC experiments, ALICE and ATLAS. In the WLCG, which coordinates computing activities for the LHC experiments, the computing center is a Tier-2. The rest of computing resources is used by astroparticle experiments Pierre Auger Observatory (PAO) and Cherenkov Telescope Array (CTA) and particle experiments like NOvA and DUNE. Storage capacity is distributed to several locations. DPM servers used by the ATLAS and the PAO are all in the same server room. ALICE uses several xrootd servers located at the Nuclear Physics Institute in Rez, about 10 km away. The storage capacity for the ATLAS and the PAO is extended by resources of the CESNET (the Czech National Grid Initiative representative) located in Ostrava, more than 100 km away from the CC FZU. Storage is managed by a dCache instance, which is published in the CC FZU BDII. ATLAS users can use these resources using the standard ATLAS tools in the same way as the local storage without noticing this geographical distribution. The computing center provides about 8k CPU cores which are used by the experiments based on fair-share. The CPUs are distributed amongst server rooms in the Institute of Physics, in the Faculty of Mathematics and Physics of the Charles University, and at CESNET. For the ATLAS experiment, the resources are extended by opportunistic usage of the Salomon HPC provided by the Czech national HPC center IT4Innovations in Ostrava. The HPC provides 24-core nodes. The maximum number of allowed single-node jobs in the batch system is 200. The contribution of the HPC to the CPU consumption by the ATLAS experiment is about 15% on average.

description: To extend the BLMSSM, we not only add exotic Higgs superfields $(Φ_{NL},φ_{NL})$ to make the exotic lepton heavy, but also introduce the superfields($Y$,$Y^\prime$) having couplings with lepton and exotic lepton at tree level. The obtained model is called as EBLMSSM, which has difference from BLMSSM especially for the exotic slepton(lepton) and exotic sneutrino(neutrino). We deduce the mass matrices and the needed couplings in this model. To confine the parameter space, the Higgs boson mass $m_{h^0}$ and the processes $h^0\rightarrow γγ$, $h^0\rightarrow VV, V=(Z,W)$ are studied in the EBLMSSM. With the assumed parameter space, we obtain reasonable numerical results according to data on Higgs from ATLAS and CMS. As a cold dark mater candidate, the relic density for the lightest mass eigenstate of $Y$ and $Y'$ mixing is also studied.

A Theory of Quantum Error-Correcting Codes

Publisher: name: arXiv
Year: 1996
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by an interaction. The conditions depend only on the behavior of the logical states. We use them to give a recovery operator independent definition of error-correcting codes. We relate this definition to four others: The existence of a left inverse of the interaction, an explicit representation of the error syndrome using tensor products, perfect recovery of the completely entangled state, and an information theoretic identity. Two notions of fidelity and error for imperfect recovery are introduced, one for pure and the other for entangled states. The latter is more appropriate when using codes in a quantum memory or in applications of quantum teleportation to communication. We show that the error for entangled states is bounded linearly by the error for pure states. A formal definition of independent interactions for qubits is given. This leads to lower bounds on the number of qubits required to correct $e$ errors and a formal proof that the classical bounds on the probability of error of $e$-error-correcting codes applies to $e$-error-correcting quantum codes, provided that the interaction is dominated by an identity component.

description: We describe a proposal for a new type of optomechanical system based on a drop of liquid helium that is magnetically levitated in vacuum. In the proposed device, the drop would serve three roles: its optical whispering gallery modes would provide the optical cavity, its surface vibrations would constitute the mechanical element, and evaporation of He atoms from its surface would provide continuous refrigeration. We analyze the feasibility of such a system in light of previous experimental demonstrations of its essential components: magnetic levitation of mm-scale and cm-scale drops of liquid He, evaporative cooling of He droplets in vacuum, and coupling to high-quality optical whispering gallery modes in a wide range of liquids. We find that the combination of these features could result in a device that approaches the single-photon strong coupling regime, due to the high optical quality factors attainable at low temperatures. Moreover, the system offers a unique opportunity to use optical techniques to study the motion of a superfluid that is freely levitating in vacuum (in the case of $^{4}\mathrm {He}$). Alternatively, for a normal fluid drop of $^3 \mathrm{He}$, we propose to exploit the coupling between the drop's rotations and vibrations to perform quantum non-demolition measurements of angular momentum.

description: There exists a long standing discrepancy of around 3.5 sigma between experimental measurements and standard model calculations of the magnetic moment of the muon. Current experiments aim to reduce the experimental uncertainty by a factor of 4, and Standard Model calculations must also be improved by a similar order. The largest uncertainty in the Standard Model calculation comes from the QCD contribution, in particular the leading order hadronic vacuum polarisation (HVP). To calculate the HVP contribution, we use lattice gauge theories which allows us to study QCD at low energies. In order to better understand this quantity, we investigate the effect of QED corrections to the leading order HVP term by including QED in our lattice calculations, and investigate flavour breaking effects. This is done using fully dynamical QCD+QED gauge configurations generated by the QCDSF collaboration and a novel method of quark turning.

description: Background: Orthostatic tremor (OT) is a disabling movement disorder manifested by postural and gait disturbance. Primarily a condition of elderly people, it can be progressive in up to 15% of patients. The primary treatments are medications that are often ineffective. Case Report: A 75-year-old male presented with a 10-year history of progressive and disabling OT. He had tried various medications without significant benefits. He underwent bilateral thalamic Vim deep brain stimulation (DBS). At 30-month follow-up, he has had continued significant improvement of his OT. Discussion: Bilateral thalamic DBS may be a viable option for medically refractory OT.

description: Using simulated data-driven three-dimensional resistive MHD simulations of the solar atmosphere, we show that magnetic reconnection can be responsible of the formation of jets with characteristic of Type II spicules. For this, we numerically model the photosphere-corona region using the C7 equilibrium atmosphere model. The initial magnetic configuration is a 3D potential magnetic field, extrapolated up to the solar corona region from a dynamic realistic simulation of solar photospheric magnetoconvection model which is mimicking quiet-Sun. In this case we consider a uniform and constant value of the magnetic resistivity of $12.56 ~Ω~{\rm m}$. We have found that formation of the jets depends on the Lorentz force, which helps to accelerate the plasma upwards. Analyzing various properties of the jet dynamics, we found that the jet structure shows Doppler shift near to regions with high vorticity. The morphology, upward velocity, covering a range up to 100 $\rm km$ $\rm s^{-1}$, and life-time of the estructure, bigger than 100 ${\rm s}$, are similar to those expected for Type II spicules.

description: An efficient coding circuit is given for the perfect quantum error correction of a single qubit against arbitrary 1-qubit errors within a 5 qubit code. The circuit presented employs a double `classical' code, i.e., one for bit flips and one for phase shifts. An implementation of this coding circuit on an ion-trap quantum computer is described that requires 26 laser pulses. A further circuit is presented requiring only 24 laser pulses, making it an efficient protection scheme against arbitrary 1-qubit errors. In addition, the performance of two error correction schemes, one based on the quantum Zeno effect and the other using standard methods, is compared. The quantum Zeno error correction scheme is found to fail completely for a model of noise based on phase-diffusion.

Publisher: name: Zenodo
Year: 2019

description: In this talk, we discuss the new physics implication in Two Higgs doublet Model (2HDM) under various experimental constraints. As part work of Gambit group, our work is to use the global fit method to constrain the parameter space, find out the hints for new physics and try to make some predictions for further studies. In our global fit, we include the constraints from LEP, LHC (SM-like Higgs boson search), the theoretical requirements ( Unitarity, Perturbativity, and vacuum stability), various flavour physics constraints ( radiative B Decay $B \to X_s \gamma$, rare fully leptonic B decays $B \to \mu^+\mu^-$ ,etc) and muon g-2 anomaly. After the 7-parameter global fit, we have a detailed study about the result, analysing individual constraints effects, finding out advantages of every constraint in constraining parameters and discovering new particles. For the Type-II 2HDM, we find that the $\lambda_2$ is sensitive to the LHC SM-lkie Higgs boson search results. Our final results will be displayed in $\tan \beta$ - $\cos(\beta-\alpha)$, $m_A$ - $\tan \beta$, which are usually considered.
Simultaneous Multiparty Communication Complexity of Composed Functions

Publisher: name: arXiv
Year: 2017
Subjects: subject: Computational Complexity (cs.CC)

description: In the Number On the Forehead (NOF) multiparty communication model, $k$ players want to evaluate a function $F : X_1 \times\cdots\times X_k\rightarrow Y$ on some input $(x_1,\dots,x_k)$ by broadcasting bits according to a predetermined protocol. The input is distributed in such a way that each player $i$ sees all of it except $x_i$. In the simultaneous setting, the players cannot speak to each other but instead send information to a referee. The referee does not know the players' input, and cannot give any information back. At the end, the referee must be able to recover $F(x_1,\dots,x_k)$ from what she obtained. A central open question, called the $\log n$ barrier, is to find a function which is hard to compute for $polylog(n)$ or more players (where the $x_i$'s have size $poly(n)$) in the simultaneous NOF model. This has important applications in circuit complexity, as it could help to separate $ACC^0$ from other complexity classes. One of the candidates belongs to the family of composed functions. The input to these functions is represented by a $k\times (t\cdot n)$ boolean matrix $M$, whose row $i$ is the input $x_i$ and $t$ is a block-width parameter. A symmetric composed function acting on $M$ is specified by two symmetric $n$- and $kt$-variate functions $f$ and $g$, that output $f\circ g(M)=f(g(B_1),\dots,g(B_n))$ where $B_j$ is the $j$-th block of width $t$ of $M$. As the majority function $MAJ$ is conjectured to be outside of $ACC^0$, Babai et. al. suggested to study $MAJ\circ MAJ_t$, with $t$ large enough. So far, it was only known that $t=1$ is not enough for $MAJ\circ MAJ_t$ to break the $\log n$ barrier in the simultaneous deterministic NOF model. In this paper, we extend this result to any constant block-width $t>1$, by giving a protocol of cost $2^{O(2^t)}\log^{2^{t+1}}(n)$ for any symmetric composed function when there are $2^{Ω(2^t)}\log n$ players.

description: We extend the investigation of general relativistic effects on the observed X-ray continuum of Kerr black holes in the context of the light bending model (Miniutti & Fabian, 2004). Assuming a ring-like illuminating source, co-rotating with the underlying accretion disk, we study the shape and normalisation of the primary and disc reflected continuum as well as the dependence of the observed spectrum on the line of sight for various source heights and radii. These calculations are performed using Monte-Carlo methods to compute the angle dependent reflection spectrum from the disc. The effects of general relativity are illustrated by a comparison with Newtonian and Special Relativity calculations. We find that relativistic distortions can strongly affect the shape of the reflected spectrum. Light bending can dramatically increase the observable reflected flux and reduce the primary emission. In addition, multiple reflections due to the reflected photons deflected toward the disc can alter significantly the shape of the spectrum above 10 keV. Large variations of the ring radius at constant height can lead to an (unobserved) anti-correlation between primary and reflected flux. In another side, the variability behaviour of several sources can be reproduced if the ring source radius is small (<5 r_g), and its height varies by a large factor. In particular, a non-linear flux-flux relation, similar to that observed in several sources, can be produced. We compare our model with the flux-flux plot of NGC4051, and find an agreement for low inclination angles (<20 deg.), ring source radius <3 r_g and a height varying between 0.5 to 10 r_g.

Publisher: name: Zenodo

description: We present a major overhaul to lepton identification for the Belle II experiment, based on a novel multi-variate classification algorithm. A key topic in the Belle II physics programme is the study of semi-tauonic B decays to test lepton flavour universality violation, such as $B\rightarrow D^{*}\tau\nu$. The analysis of this decay relies on the capability of correctly separating low momentum, lepton candidates ($e$, $\mu$) in the decay of the $\tau$ from hadronic background. At the mean momentum of $\leq 500$ MeV/c, muons do not reach the dedicated muon detector (KLM) , therefore methods must be developed to identify them with the electromagnetic calorimeter (ECL). Furthermore, at low momenta electrons suffer significant energy losses due to bremsstrahlung, making them more easily mimicked by hadrons. Boosted decision trees are trained combining measurements from the ECL and tracking system. The chosen observables are sensitive to the different physics that governs interactions of hadrons, electrons and muons with the calorimeter crystals. Dedicated classifiers are used in various detector regions and lepton momentum ranges. The tree output is eventually combined with other classifiers that rely upon independent measurements from other sub-detectors. Using simulation, the performance of the new algorithm is compared against the method used for analysis of the 2018 Belle II data, namely a likelihood discriminator based on the ratio of energy measured in the ECL over the momentum measured by the trackers. In the critical low momentum region, we largely improve the lepton-pion separation power, increasing background rejection up to 50% for the same electron/muon signal efficiency. The algorithm has been integrated into the Belle II Analysis Software Framework, and is used in the processing of the 2019 collision dataset. Its performance in the 2019 run will be covered in the presentation.

description: Inelastic neutron scattering measurements on the itinerant antiferromagnet (AFM) CaCo$_{\mathrm{2}-y}$As$_{2}$ at a temperature of 8 K reveal two orthogonal planes of scattering perpendicular to the Co square lattice in reciprocal space, demonstrating the presence of effective one-dimensional spin interactions. These results are shown to arise from near-perfect bond frustration within the $J_1$-$J_2$ Heisenberg model on a square lattice with ferromagnetic $J_1$, and hence indicate that the extensive previous experimental and theoretical study of the $J_1$-$J_2$ Heisenberg model on local-moment square spin lattices should be expanded to include itinerant spin systems.

The extrapolations are carried out by keeping $ρ$ and $π$ masses at fixed values. We find an $η'$ -- $π$ splitting which shows a flavour dependence consistent with the Witten Veneziano formula based on the $U(1)$ anomaly. The quantitative splitting is consistent with the estimates made in the quenched approximation.

description: In some laboratory and most astrophysical situations plasma wake-field acceleration of electrons is one dimensional, i.e. variation transverse to the beam's motion can be ignored. Thus, one dimensional (1D), particle-in-cell (PIC), fully electromagnetic simulations of electron plasma wake field acceleration are conducted in order to study the differences in electron plasma wake field acceleration in MeV versus GeV and linear versus blowout regimes. First, we show that caution needs to be taken when using fluid simulations, as PIC simulations prove that an approximation for an electron bunch not to evolve in time for few hundred plasma periods only applies when it is sufficiently relativistic. This conclusion is true irrespective of the plasma temperature. We find that in the linear regime and GeV energies, the accelerating electric field generated by the plasma wake is similar to the linear and MeV regime. However, because GeV energy driving bunch stays intact for much longer time, the final acceleration energies are much larger in the GeV energies case. In the GeV energy range and blowout regime the wake's accelerating electric field is much larger in amplitude compared to the linear case and also plasma wake geometrical size is much larger. Thus, the correct positioning of the trailing bunch is needed to achieve the efficient acceleration. For the considered case, optimally there should be approximately $(90-100) c/ω_{pe}$ distance between trailing and driving electron bunches in the GeV blowout regime.

Musical Style and Experience in a Brooklyn Pentecostal Church: An "Insider's" Perspective

description: When my wife, Lori, speaks of her move from Charlotte, North
Carolina, to attend college in Boston, Massachusetts, she inevitably highlights
the "culture shock" she felt upon first arriving. "I don't like it. It's
different," she tearfully tried to explain to her parents late one Sunday
afternoon. Her voice had an air of despair that seemed to belie the faithbred
optimism she usually portrayed even when things didn't go her way.
Lori was raised Pentecostal "from the womb," as the saying goes, and her
church background is steeped in the African American Pentecostal tradition.
A couple of hours before, she had returned from church, thrown
herself on her dorm room bed, and burst into tears. This was not a matter
of simply adjusting to the climatic or culinary foreignness of New England,
nor was it a temporary bout of homesickness one might expect from a pastor's
youngest daughter. Rather, what had made life in Boston suddenly
seem so unbearable was the fact that, for her, West Indian-style musical
worship had hindered the spiritual fulfillment she expected to receive in a
Pentecostal setting. Church, she thought, was supposed to be something
familiar-something enjoyable. Her parents had recommended that she
attend this church; but perhaps even they were unaware it would be so "different."
Weren't all black Pentecostal churches in the United States more
or less the same?

Creators: name: Pedro, Kevin
Publisher: name: Zenodo
Year: 2019

description: The HL-LHC and the corresponding detector upgrades for the CMS experiment will present extreme challenges for the full simulation. In particular, increased precision in models of physics processes may be required for accurate reproduction of particle shower measurements from the upcoming High Granularity Calorimeter. The CPU performance impacts of several proposed physics models will be discussed. There are several ongoing research and development efforts to make efficient use of new computing architectures and high performance computing systems for simulation. The integration of these new R&D products in the CMS software framework and corresponding CPU performance improvements will be presented.

description: Background/Aims: Sociocultural and familial factors associated with weight bias internalization (WBI) are currently unknown. The present study explored the relationship between interpersonal sources of weight stigma, family weight history, and WBI. Methods: Participants with obesity (N = 178, 87.6% female, 71.3% black) completed questionnaires that assessed the frequency with which they experienced weight stigma from various interpersonal sources. Participants also reported the weight status of their family members and completed measures of WBI, depression, and demographics. Participant height and weight were measured to calculate body mass index (BMI). Results: Linear regression results (controlling for demographics, BMI, and depression) showed that stigmatizing experiences from family and work predicted greater WBI. Experiencing weight stigma at work was associated with WBI above and beyond the effects of other sources of stigma. Participants who reported higher BMIs for their mothers had lower levels of WBI. Conclusion: Experiencing weight stigma from family and at work may heighten WBI, while having a mother with a higher BMI may be a protective factor against WBI. Prospective research is needed to understand WBI's developmental course and identify mechanisms that increase or mitigate its risk.
Outside Forces: "Autumn Leaves" in the 1960s

description: Is there a problem of form in the jazz tradition? Does the reliance upon
repeated 32-bar frameworks create an unavoidable formal, harmonic, and
metric redundancy? How do jazz improvisers transcend or evade this
cyclic regularity?
These are crucial questions. Jazz players have extended privilege to the
32-bar AABA and ABAC song form (along with 12-bar blues structures)
since at least the 1930s, when the 32-bar song form replaced the 16-bar
sectional forms of ragtime and early jazz. Yet repeated cycles of thirty-two
bars result in a hypermetric consistency on several levels: single measures
group into four-measure units, which then combine into eight measure
sections; the four eight-measure sections comprise the 32-bar form, which
becomes repeated, normally for the duration of the composition. In the
Western European tradition (with the occasional exception of the theme
and variations genre and dance forms) form is typically not generated by
regularly repeating structures, structures that are consistently built from
measure groups of 4, 8, 16, and 32 bars. Yet this formal model, with its
foursquare regularity and its repeated harmonic and metric organization,
has been one of the primary vehicles for jazz improvisers and composers.
Historically, jazz players have kept the structure, merely renovating it periodically
through stylistic change. Thus, while stylistic development and
evolution has rapidly taken place in the area of instrumental technique,
harmony, and rhythm, the domain of form has remained relatively static.
Exploiting network restricted compute resources with HTCondor: a CMS experiment experience
Creators: name: Molina, Jose Flix
Publisher: name: Zenodo
Year: 2019

description: In view of the increasing computing needs for the HL-LHC era, the LHC experiments are exploring new ways to access, integrate and use non-Grid compute resources. Accessing and making efficient use of Cloud and supercomputer (HPC) resources present a diversity of challenges. In particular, network limitations from the compute nodes in HPC centers impede CMS experiment pilot jobs to connect to its central HTCondor pool to receive the actual payload jobs to be executed. To cope with this limitation, new features have been developed in both HTCondor and the CMS resource scheduling and workload management infrastructure. In this novel approach, a bridge is set up outside the HPC center and the communications between HTCondor daemons are relayed through a shared file system. We have used this strategy to exploit the Barcelona Supercomputing Center (BSC) resources, the main Spanish HPC site. CMS payloads are claimed by HTCondor startd daemons running at the nearby PIC Tier-1 center and routed to BSC compute nodes through the bridge. This fully enables the connectivity of CMS HTCondor-based central infrastructure to BSC resources via PIC HTCondor pool. Other challenges have included building custom Singularity images with CMS software releases, bringing conditions data to payload jobs, and custom data handling between BSC and PIC. This contribution describes this technical prototype, its deployment, the functionality and scalability tests performed, along with the results obtained when exploiting the BSC resources using these novel approaches. A key aspect of the technique described in this contribution is that it could be universally employed in similar HPC environments elsewhere.
The Ultraluminous X-ray Source in Holmberg IX and its Environment

description: We present optical observations of an ultraluminous X-ray source (ULX) in Holmberg IX, a dwarf galaxy near M81. The ULX has an average X-ray luminosity of some 10^{40} erg/s. It is located in a huge (400pc x 300pc) ionized nebula being much larger than normal supernova remnants. From the observed emission lines (widths and ratios) we find that the structure is due to collisional excitation by shocks, rather than by photoionization. We identify the optical counterpart to be a 22.8 mag blue star (M_V=-5.0) belonging to a small stellar cluster. From isochrone fitting of our multi-colour photometry we determine a cluster age of 20 to 50 Myr. We also discovered strong stellar HeII4686 emission (equivalent width of 10 A) which proves the identification with the X-ray source, and which suggests the presence of an X-ray heated accretion disc around the putative black hole.

description: We resolve a discrepancy between the SU(2) spacial string tension at finite temperature, and the value obtained by monopoles in the maximum Abelian gauge. Previous work had incorrectly omitted a term due to Dirac sheets. When this term is included, the monopole and full SU(2) determinations of the spacial string tension agree to within the statistical errors of the monopole calculation.

On a relation between the volume of fluid, level-set and phase field interface models

description: This paper discusses a relation between the re-initialization equation of the level-set functions derived by Wacławczyk [J.Comp.Phys., 299, (2015)] and the condition for the phase equilibrium provided by the stationary solution to the modified Allen-Cahn equation [Acta Metall., 27, (1979)]. As a consequence, the statistical model of the non-flat interface in the state of phase equilibrium is postulated. This new physical model of the non-flat interface is introduced based on the statistical picture of the sharp interface disturbed by the field of stochastic forces, it yields the relation between the sharp and diffusive interface models. Furthermore, the new techniques required for the accurate solution of the model equations are proposed. First it is shown, the constrained interpolation improves re-initialization of the level-set functions as it avoids oscillatory numerical errors typical for the second-order accurate interpolation schemes. Next, the new semi-analytical, second order accurate Lagrangian scheme is put forward to integrate the advection equation in time avoiding interface curvature oscillations introduced by the second-order accurate flux limiters. These techniques provide means to obtain complete, second-order convergence during advection and re-initialization of the interface in the state of phase equilibrium.

A Mathematical Theory for Vibrational Levels Associated with Hydrogen Bonds I: The Symmetric Case

description: We propose an alternative to the usual time--independent Born--Oppenheimer approximation that is specifically designed to describe molecules with symmetrical Hydrogen bonds. In our approach, the masses of the Hydrogen nuclei are scaled differently from those of the heavier nuclei, and we employ a specialized form for the electron energy level surface. Consequently, anharmonic effects play a role in the leading order calculations of vibrational levels. Although we develop a general theory, our analysis is motivated by an examination of symmetric bihalide ions, such as FHF- or ClHCl-. We describe our approach for the FHF- ion in detail.

description: Mark Tucker was one of those rare individuals who excelled in all the
areas one might invoke in assessing a musical scholar's importance. His
two books and numerous essays on Duke Ellington and his public presentations
on Thelonious Monk have all contributed to our recognition of
him as a first-rate musicologist and jazz scholar, one whose work is beautifully
written and brimming with insight. His research on Ellington's early
years has enhanced our understanding of how one of America's most
celebrated composers developed his craft. By situating Ellington in the
complex worlds of Washington, D.C. and Harlem up to the 1930s, Mark
helped open the door to a more nuanced investigation of jazz, going
beyond hagiography or decontextualized musical analysis to render a
complex portrait worthy of his subject. His unfinished monograph on
Thelonious Monk promised to go in the same direction. A presentation
for Columbia's Center for Jazz Studies lecture series in 2000 showed Mark
succeeding at disentangling Monk the myth from Monk the musician, and
in the process bringing many who thought they understood Monk to a
new level of awareness.
Relative Haag Duality for the Free Field in Fock Representation

description: We consider a natural generalization of Haag duality to the case in which the observable algebra is restricted to a subset of the space-time and is not irreducible: the commutant and the causal complement have to be considered relatively to the ambient space. We prove this relative form of Haag duality under quite general conditions for the free scalar and electromagnetic field of space dimension d>1 in the vacuum representation. Such property is interesting in view of a theory of superselection sectors for the electromagnetic field.
