description: We present detailed model fits to observations of the disc around the Herbig Ae star HD 163296. This well-studied object has an age of ~ 4 Myr, with evidence of a circumstellar disc extending out to ~ 540AU. We use the radiation thermo-chemical disc code ProDiMo to model the gas and dust in the circumstellar disc of HD 163296, and attempt to determine the disc properties by fitting to observational line and continuum data. These include new Herschel/PACS observations obtained as part of the open-time key program GASPS (Gas in Protoplanetary Systems), consisting of a detection of the [OI]63mic line and upper limits for several other far infrared lines. We complement this with continuum data and ground-based observations of the 12CO 3-2, 2-1 and 13CO J=1-0 line transitions, as well as the H2 S(1) transition. We explore the effects of stellar ultraviolet variability and dust settling on the line emission, and on the derived disc properties. Our fitting efforts lead to derived gas/dust ratios in the range 9-100, depending on the assumptions made. We note that the line fluxes are sensitive in general to the degree of dust settling in the disc, with an increase in line flux for settled models. This is most pronounced in lines which are formed in the warm gas in the inner disc, but the low excitation molecular lines are also affected. This has serious implications for attempts to derive the disc gas mass from line observations. We derive fractional PAH abundances between 0.007 and 0.04 relative to ISM levels. Using a stellar and UV excess input spectrum based on a detailed analysis of observations, we find that the all observations are consistent with the previously assumed disc geometry.

On the locus formed by the maximum heights of an ultra-relativistic projectile

Subjects: subject: Classical Physics (physics.class-ph)

description: We consider the problem of relativistic projectiles in a uniform gravitational force field in an inertial frame. For the first time, we have found the curve that joins the points of maximum height of all trajectories followed by a projectile in the ultra-relativistic limit. The parametric equations of this curve produce an onion-like curve; in fact, it is one of the loops of a lemniscate-type curve. We also verify that the curve is an ellipse in the nonrelativistic approximation. These two limiting results are obtained by following two slightly distinct approaches. In addition, we calculate the nonrelativistic and ultra-relativistic approximations of the trajectory equation and parametric equations of the trajectory as functions of time. We also find the asymptotic behavior of the ultra-relativistic trajectory equations for points that are very distant from the launching point. All limiting cases in the article are studied in detail. Additionally, we discuss various physical issues related to some of our results. The content of the article is appropriate for advanced undergraduate students.

description: We describe a parallelised version of the MOLDY molecular dynamics program. This Fortran code is aimed at systems which may be described by short-range potentials and specifically those which may be addressed with the embedded atom method. This includes a wide range of transition metals and alloys. MOLDY provides a range of options in terms of the molecular dynamics ensemble used and the boundary conditions which may be applied. A number of standard potentials are provided, and the modular structure of the code allows new potentials to be added easily. The code is parallelised using OpenMP and can therefore be run on shared memory systems, including modern multicore processors. Particular attention is paid to the updates required in the main force loop, where synchronisation is often required in OpenMP implementations of molecular dynamics. We examine the performance of the parallel code in detail and give some examples of applications to realistic problems, including the dynamic compression of copper and carbon migration in an iron-carbon alloy.

description: We co-added the available XMM-Newton RGS spectra for each of the isolated X-ray pulsars RX\,J0720.4$-$3125, RX\,J1308.6+2127 (RBS\,1223), RX\,J1605.3+3249 and RX\,J1856.4$-$3754 (four members of the "Magnificent Seven") and the "Three Musketeers" Geminga, PSR\,B0656+14 and PSR\,B1055-52. We confirm the detection of a narrow absorption feature at 0.57 keV in the co-added RGS spectra of RX\,J0720.4$-$3125 and RX\,J1605.3+3249 (including most recent observations). In addition we found similar absorption features in the spectra of RX\,J1308.6+2127 (at 0.53 keV) and maybe PSR\,B1055-52 (at 0.56 keV). The absorption feature in the spectra of RX\,J1308.6+2127 is broader than the feature e.g. in RX\,J0720.4$-$3125. The narrow absorption features are detected with 2$σ$ to 5.6$σ$ significance. Although very bright and frequently observed, there are no absorption features visible in the spectra of RX\,J1856.4$-$3754 and PSR\,B0656+14, while the co-added XMM-Newton RGS spectrum of Geminga has not enough counts to detect such a feature. We discuss a possible origin of these absorption features as lines caused by the presence of highly ionised oxygen (in particular OVII and/or OVI at 0.57 keV) in the interstellar medium and absorption in the neutron star atmosphere, namely the absorption features at 0.57 keV as gravitational redshifted ($g_{r}$=1.17) OVIII.

Stability analysis of a viscoelastic model for ion-irradiated silicon

description: To study the effect of stress within the thin amorphous film generated atop Si irradiated by Ar+, we model the film as a viscoelastic medium into which the ion beam continually injects biaxial compressive stress. We find that at normal incidence, the model predicts a steady compressive stress of a magnitude comparable to experiment. However, linear stability analysis at normal incidence reveals that this mechanism of stress generation is unconditionally stabilizing due to a purely kinematic material flow, depending on none of the material parameters. Thus, despite plausible conjectures in the literature as to its potential role in pattern formation, we conclude that beam stress at normal incidence is unlikely to be a source of instability at any energy, supporting recent theories attributing hexagonal ordered dots to the effects of composition. In addition, we find that the elastic moduli appear in neither the steady film stress nor the leading order smoothening, suggesting that the primary effects of stress can be captured even if elasticity is neglected. This should greatly simplify future analytical studies of highly nonplanar surface evolution, in which the beam-injected stress is considered to be an important effect.

description: We develop the generalized rotating-wave approximation (GRWA) approach (Phys. Rev. Lett. 99, 173601 (2007)) to study the single-photon scattering on a two-level system (TLS) with arbitrarily strong coupling to a local mode in a one-dimensional (1D) coupled resonator array. We calculate the scattering amplitudes analytically, and the independent numerical results show that our approach works well in a broad parameter region. Especially, when the resonator mode is faroff resonance with the TLS, we obtain more reasonable results than the ones from the standard adiabatic approximation. Our approach is further extended to the cases with a 1D resonator array strongly coupled to more than one TLSs.

LSST will survey half the sky every few nights in six optical bands. The data will be transferred to NCSA and within 60 seconds they will be reduced using difference imaging techniques and detected transients will be announced to the community in the VOEvent format. Annual data releases will be made from all the data during the 10-year mission, with unprecedented depth of coadds and time resolution of catalogs for such a large region of sky. Here we present the current status of the data processing software, and describe how to obtain it.

Essays on natural gas price behavior

Publisher: name: University of Calgary

description: Bibliography: p. 125-129
description: To analyze patterns in the behavior of North American natural gas prices, we consider a number of topics, which are organized in separate chapters. The second chapter introduces the reader not familiar with the energy industry to the North American gas and the world oil commodity markets. The rest of the chapters would be useful for the energy market participants interested in modeling energy price behavior. We examine statistical properties of the Henry Hub natural gas price series over the deregulated period starting 1991. We also examine the properties of the WTI oil price where appropriate, as we distinguish between the oil market being a world commodity market, and the natural gas market being a North American market. We look for possible dependencies in the behavior of the commodity prices on spot and futures markets while testing for effectiveness of futures price formation. We also address a macro-economic issue of the cyclical patterns in natural gas and oil prices behavior.

description: We find some exact solutions for constant-density and quark matter equations of state in stellar structure models framed within the $f(R,T)=R+λκ^2 T$ theory of gravity, where $R$ is the curvature scalar, $T$ the trace of the stress-energy tensor, and $λ$ some constant. These solutions correspond to specific values of the constant $λ$, and represent different compactness states of the corresponding stars, though only those made of quark matter can be regarded as physical. The latter modify the compactness (Buchdahl) limit of neutron stars upwards for $λ>0$ until saturating the one of black holes. Our results show that it is possible to find useful insights on stellar structure in this class of theories, a fact that could be used for obtaining constraints on limiting masses such as the minimum hydrogen burning mass.

description: We study the dynamics of an atomic Bose-Einstein condensate in an optical lattice in which the electronic groundstate of each atom is weakly coupled to a highly excited Rydberg state by a far off-resonant laser. This dressing induces a switchable effective soft-core interaction between groundstate atoms which, in the lattice, gives rise to on-site as well as long-range interaction terms. Upon switching on the dressing laser the Bose-Einstein condensate undergoes a nontrivial collapse and revival dynamics which can be observed in the interference pattern that is created after a release of the atoms from the optical lattice. This interference signal strongly depends on the strength and the duration of the dressing laser pulse and can be used to probe and characterize the effective interaction between Rydberg-dressed atoms.

description: Precision optical measurements of the electron-spin precession of nitrogen-vacancy (NV) centers in diamond form the basis of numerous applications. The most sensitivity-demanding applications, such as femtotesla magnetometry, require the ability to measure changes in GHz spin transition frequencies at the sub-millihertz level, corresponding to a fractional resolution of better than 10^{-12}. Here we study the impact of microwave (MW) phase noise on the response of an NV sensor. Fluctuations of the phase of the MW waveform cause undesired rotations of the NV spin state. These fluctuations are imprinted in the optical readout signal and, left unmitigated, are indistinguishable from magnetic field noise. We show that the phase noise of several common commercial MW generators results in an effective pT s^{1/2}-range noise floor that varies with the MW carrier frequency and the detection frequency of the pulse sequence. The data are described by a frequency domain model incorporating the MW phase noise spectrum and the filter-function response of the sensing protocol. For controlled injection of white and random-walk phase noise, the observed NV magnetic noise floor is described by simple analytic expressions that accurately capture the scaling with pulse sequence length and the number of pi pulses. We outline several strategies to suppress the impact of MW phase noise and implement a version, based on gradiometry, that realizes a >10-fold suppression. Our study highlights an important challenge in the pursuit of sensitive diamond quantum sensors and is applicable to other qubit systems with a large transition frequency.

description: This study uses CAPM (Convex Adversarial Polytope for Maxpool-based CNN) to improve the verified bound for general purpose maxpool-based convolutional neural networks (CNNs) under bounded norm adversarial perturbations. The maxpool function is decomposed as a series of ReLU functions to extend the convex relaxation technique to maxpool functions, by which the verified bound can be efficiently computed through a dual network. The experimental results demonstrate that this technique allows the state-of-the-art verification precision for maxpool-based CNNs and involves a much lower computational cost than current verification methods, such as DeepZ, DeepPoly and PRIMA. This method is also applicable to large-scale CNNs, which previous studies show to be often computationally prohibitively expensive. Under certain circumstances, CAPM is 40-times, 20-times or twice as fast and give a significantly higher verification bound (CAPM 98% vs. PRIMA 76%/DeepPoly 73%/DeepZ 8%) as compared to PRIMA/DeepPoly/DeepZ. Furthermore, we additionally present the time complexity of our algorithm as $O(W^2NK)$, where $W$ is the maximum width of the neural network, $N$ is the number of neurons, and $K$ is the size of the maxpool layer's kernel.
Bayesian Linking of Geosynchronous Orbital Debris Tracks as seen by the Large Synoptic Survey Telescope

Year: 2011
Subjects: subject: Space Physics (physics.space-ph)

description: We describe a Bayesian sampling model for linking and constraining orbit models from angular observations of "streaks" in optical telescope images. Our algorithm is particularly suited to situations where the observation times are small fractions of the orbital periods of the observed objects or when there is significant confusion of objects in the observation field. We use Markov Chain Monte Carlo to sample from the joint posterior distribution of the parameters of multiple orbit models (up to the number of observed tracks) and parameters describing which tracks are linked with which orbit models. Using this algorithm, we forecast the constraints on geosynchronous (GEO) debris orbits achievable with the planned Large Synoptic Survey Telescope (LSST). Because of the short 15 second exposure times, preliminary orbit determinations of GEO objects from LSST will have large and degenerate errors on the orbital elements. Combined with the expected crowded fields of GEO debris it will be challenging to reliably link orbital tracks in LSST observations given the currently planned observing cadence.

description: The current state of shadowing of the labour market is a threatening trend in national security of Ukraine, as it directly affects the socio-economic development of society. Shadow employment is considered as illegal involvement of an employee in economic activities by the employer. In view of this, we substantiate that the labour market with its destructive development may endanger the vital national interests of Ukraine as it covers the entire working population of the state and forms the economic potential of the state. With the help of PESTL-analysis, in order to identify large-scale problems of the labour market, the range of factors shadowing the labour and employment market, including political; economic; socio-demographic; regulatory. The study shows that the negative and destructive impact of these factors extends not only to the labour and employment market, but also to the economy, social protection, demographic situation and social development of Ukraine as a whole, which threatens the national security of Ukraine.

Zatrudnienie w szarej strefie traktowane jest jako nielegalne angażowanie się pracownika w działalność gospodarczą przez pracodawcę. W związku z tym uzasadniamy, że rynek pracy ze swym destrukcyjnym rozwojem może zagrażać interesom narodowym Ukrainy, gdyż obejmuje całą ludność pracującą państwa i tworzy jego potencjał gospodarczy. W celu zidentyfikowania wielkoskalowych problemów rynku pracy, szeregu czynników zacieniających rynek pracy i zatrudnienie, w tym regulacje polityczne, gospodarcze, społeczno-demograficzne, zastosowano analizę PESTL.

description: The X-ray and near-IR emission from Sgr A* is dominated by flaring, while a quiescent component dominates the emission at radio and sub-mm wavelengths. The spectral energy distribution of the quiescent emission from Sgr A* peaks at sub-mm wavelengths and is modeled as synchrotron radiation from a thermal population of electrons in the accretion flow, with electron temperatures ranging up to $\sim 5-20$\,MeV. Here we investigate the mechanism by which X-ray flare emission is produced through the interaction of the quiescent and flaring components of Sgr A*. The X-ray flare emission has been interpreted as inverse Compton, self-synchrotron-Compton, or synchrotron emission. We present results of simultaneous X-ray and near-IR observations and show evidence that X-ray peak flare emission lags behind near-IR flare emission with a time delay ranging from a few to tens of minutes. Our Inverse Compton scattering modeling places constraints on the electron density and temperature distributions of the accretion flow and on the locations where flares are produced. In the context of this model, the strong X-ray counterparts to near-IR flares arising from the inner disk should show no significant time delay, whereas near-IR flares in the outer disk should show a broadened and delayed X-ray flare.

description: We present an analysis of the 15 February 2011 X-class solar flare, previously reported to produce the first sunquake in solar cycle 24 (Kosovichev 2011). Using acoustic holography, we confirm the first, and report a second, weaker, seismic source associated with this flare. We find that the two sources are located at either end of a sigmoid which indicates the presence of a flux rope. Contrary to the majority of previously reported sunquakes, the acoustic emission precedes the peak of major hard X-ray (HXR) sources by several minutes. Furthermore, the strongest hard X-ray footpoints derived from RHESSI data are found to be located away from the seismic sources in the flare ribbons. We account for these discrepancies within the context of a phenomenological model of a flux rope eruption and accompanying two-ribbon flare. We propose that the sunquakes are triggered at the footpoints of the erupting flux rope at the start of the flare impulsive phase and eruption onset, while the main hard X-ray sources appear later at the footpoints of the flare loops formed under the rising flux rope. Possible implications of this scenario for the theoretical interpretation of the forces driving sunquakes are discussed.

Complimentary workshops explored included: advanced technical discussion of the use and demonstration of the iBOSS real-time monitoring, decision making, and response management for optimized production the regulatory framework for valorization of aquaculture sludge and waste water, waste capture, processing and use for producing aquafeed ingredients assessment of circular aquaculture value chains opportunities for the aquaculture industry in the EU framework program for research and innovation, future project ideation and funding opportunities Waste2Value circular aquaculture value-chain is demonstrated in the iFishIENCi project in the valorisation of by-products from RAS for the production of microalgae and yeast for use as novel feed ingredients. The waste-water was directly usable as a growth medium for the cultivation of photoautotrophic microalgae (freshwater Chlorella vulgaris and marine Microchloropsis gaditana), with phosphate being the main limiting nutrient. Yeast Candida utilis could not be successfully cultured directly on waste-water or unconcentrated sludge from the RAS due to the low organic carbon content, but treated sludge showed potential. Microalgae and yeast were integrated into fish feed as functional ingredients and the feed was tested in nutritional trials on rainbow trout, African catfish, Asian seabass and tilapia. This resource is best enjoyed in association with the video recording available of the iFishIENCi YouTube Channel .

Strategies and decision-making in self-care for urinary incontinence
Creators: name: Milne, Jill L.
Publisher: name: Nursing

description: Bibliography: p. 141-157
description: Urinary incontinence (UI) is a prevalent condition with a wide range of psychosocial impact. Behavioral therapies such as pelvic floor muscle exercises, bladder training, and dietary modification are generally considered to be the first line of treatment because of their non-invasive nature, yet little is known about the ability/motivation of individuals to maintain them and current evidence suggests performance may be sporadic at best. The purpose of this qualitative descriptive study was to enhance understanding about the strategies people with UI perform at home, factors that influence their self-care choices, and factors that facilitate or impede on-going performance of behavioural therapies. Three major themes emerged from qualitative content analysis of individual (n=25) and focus group (n=3) interviews. First, participants' self-care efforts were motivated by the desire for a normal lifestyle. Strategies perceived to be personally disruptive (for example bladder training) were either not initiated or not maintained. Second, seeing enhanced believing. Participants were motivated by first or second-hand experience of UI, by experiencing the positive or negative consequences of their self-care behavior, and by heightened awareness of progress through biofeedback and follow-up. Finally, barriers to UI care persist at personal and societal levels. Social stigmatization, self-blame, financial cost, and unclear care pathways had negatively impacted participants' help-seeking behaviour and care. Findings suggest the need to focus on individual as well as social realities of UI and UI care and develop therapeutic interventions that enable sufficient choice and flexibility to promote quality of life.

description: Majorana fermions are particles identical to their own antiparticles. They have been theoretically predicted to exist in topological superconductors. We report electrical measurements on InSb nanowires contacted with one normal (Au) and one superconducting electrode (NbTiN). Gate voltages vary electron density and define a tunnel barrier between normal and superconducting contacts. In the presence of magnetic fields of order 100 mT we observe bound, mid-gap states at zero bias voltage. These bound states remain fixed to zero bias even when magnetic fields and gate voltages are changed over considerable ranges. Our observations support the hypothesis of Majorana fermions in nanowires coupled to superconductors.

Updated Search for Electron Antineutrino Appearance at MiniBooNE
Creators: name: Zimmerman, E. D.
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The MiniBooNE experiment at Fermilab has updated its search for ν_μ-bar -> ν_e-bar oscillations with data collected through May 2011. This represents a statistics increase of 52% over the result published in 2010. The data favor LSND-like oscillations over a background-only hypothesis at the 91.1% confidence level. While the new result remains equally consistent with LSND, the compatibility with the background-only hypothesis is improved. An excess of 38.6 +- 18.5 ν_e-like events below 475 MeV is observed, consistent with the observation of such an excess in neutrino mode.

description: The thermal coefficient of resistance (TCR) for epitaxial silicon-germanium (SiGe) layers has been analyzed by experiment and simulation. Predictive simulation using drift-diffusion formalism and self-consistent quantum-mechanical solutions yielded similar results, TCR around 2%/K at 300 K. This modeling approach can be used for different, graded and constant, SiGe profiles,. It is also capable of predicting the influence of background auto-doping on the TCR of the detectors
Decentralized Delay Optimal Control for Interference Networks with Limited Renewable Energy Storage

description: In this paper, we consider delay minimization for interference networks with renewable energy source, where the transmission power of a node comes from both the conventional utility power (AC power) and the renewable energy source. We assume the transmission power of each node is a function of the local channel state, local data queue state and local energy queue state only. In turn, we consider two delay optimization formulations, namely the decentralized partially observable Markov decision process (DEC-POMDP) and Non-cooperative partially observable stochastic game (POSG). In DEC-POMDP formulation, we derive a decentralized online learning algorithm to determine the control actions and Lagrangian multipliers (LMs) simultaneously, based on the policy gradient approach. Under some mild technical conditions, the proposed decentralized policy gradient algorithm converges almost surely to a local optimal solution. On the other hand, in the non-cooperative POSG formulation, the transmitter nodes are non-cooperative. We extend the decentralized policy gradient solution and establish the technical proof for almost-sure convergence of the learning algorithms. In both cases, the solutions are very robust to model variations. Finally, the delay performance of the proposed solutions are compared with conventional baseline schemes for interference networks and it is illustrated that substantial delay performance gain and energy savings can be achieved.

description: Since the discovery of the Higgs boson at the LHC, its use as a probe to search for beyond the standard model physics, such as supersymmetry, has become important, as seen in a recent search by the CMS experiment using razor variables in the diphoton final state. Motivated by this search, this thesis examines the LHC discovery potential of a SUSY scenario involving bottom squark pair production with a Higgs boson in the final state. We design and implement a software-based trigger using the razor variables for the CMS experiment to record events with a bottom quark-antiquark pair from a Higgs boson. We characterize the full range of signatures at the LHC from this Higgs-aware SUSY scenario and demonstrate the sensitivity of the CMS data to this model.

description: Neutron scattering in strong magnetic fields is used to show the spin-resonance in superconducting CeCoIn5 (Tc=2.3 K) is a doublet. The underdamped resonance (\hbar Γ=0.069 \pm 0.019 meV) Zeeman splits into two modes at E_{\pm}=\hbar Ω_{0}\pm gμ_{B} μ_{0}H with g=0.96 \pm 0.05. A linear extrapolation of the lower peak reaches zero energy at 11.2 \pm 0.5 T, near the critical field for the incommensurate "Q-phase" indicating that the Q-phase is a bose condensate of spin excitons.

description: Die europäischen Grundfreiheiten verbürgen den im Gemeinschaftsgebiet ansässigen Unternehmen eine umfassende Niederlassungsfreiheit. Eine Ausprägung der Niederlassungsfreiheit stellt auch die Verlegung des Unternehmenssitzes dar. Nationalstaatliche Beschränkungen der Sitzverlegungen wurden demzufolge in einer Reihe von Urteilen durch den EuGH für unzulässig befunden. Dessen ungeachtet existiert immer noch kein europäisches Sekundärrecht, das Voraussetzungen und Anforderungen einer Sitzverlegung einheitlich festlegt. Die Entwicklung der Rechtsprechung des EuGH zur Sitzverlegung, die noch bestehenden Regelungslücken und die daraus resultierende fortbestehende Notwendigkeit einer Sitzverlegungsrichtlinie sind Gegenstand des folgenden Beitrags. The European Unions’ fundamental freedoms seek to guarantee a capacious freedom of establishment for companies within the Union. One specification of this freedom of establishment is the transfer of the company seat to a member state other than the member state of incorporation. Thus the European Court of Justice declared national restrictions on the transfer of a company seat in a series of judgments to be incongruous with the freedom of establishment. Regardless of this fact still there does not exist a European secondary law that determines consistent requirements and conditions for such an operation. The developments in case law, the still unregulated issues and the continuous need of a directive on the transfer of a company seat are the topic of the following article.

description: Angle resolved photoemission spectroscopy of Ba(Fe1-xCox)2As2 (x = 0.06, 0.14, and 0.24) shows that the width of the Fe 3d yz/zx hole band depends on the doping level. In contrast, the Fe 3d x^2-y^2 and 3z^2-r^2 bands are rigid and shifted by the Co doping. The Fe 3d yz/zx hole band is flattened at the optimal doping level x = 0.06, indicating that the band renormalization of the Fe 3d yz/zx band correlates with the enhancement of the superconducting transition temperature. The orbital-dependent and doping-dependent band renormalization indicates that the fluctuations responsible for the superconductivity is deeply related to the Fe 3d orbital degeneracy.
