description: We investigate the linear stability of dewetting thin polymer films on hydrophobised substrates driven by Van-der-Waals forces, using a lubrication model. We focus on the role of slippage in the emerging instability at the three-phase contact-line and compare our results to the corresponding no-slip case. Our analysis shows that generically, small perturbations of the receding front are amplified, but in the slippage case by orders of magnitude larger than in the no-slip case. Moreover, while the perturbations become symmetrical in the no-slip case, they are asymmetrical in the slippage case. We furthermore extend our lubrication model to include effects of nonlinear curvature.

description: Context. Closed-loop Doppler data obtained by deep space tracking networks (e.g., NASA's DSN and ESA's Estrack) are routinely used for navigation and science applications. By "shadow tracking" the spacecraft signal, Earth-based radio telescopes involved in Planetary Radio Interferometry and Doppler Experiment (PRIDE) can provide open-loop Doppler tracking data when the dedicated deep space tracking facilities are operating in closed-loop mode only. Aims. We explain in detail the data processing pipeline, discuss the capabilities of the technique and its potential applications in planetary science. Methods. We provide the formulation of the observed and computed values of the Doppler data in PRIDE tracking of spacecraft, and demonstrate the quality of the results using as a test case an experiment with ESA's Mars Express spacecraft. Results. We find that the Doppler residuals and the corresponding noise budget of the open-loop Doppler detections obtained with the PRIDE stations are comparable to the closed-loop Doppler detections obtained with the dedicated deep space tracking facilities.

description: The paper is devoted to the analysis of the calmness property for constraint set mappings. After some general characterizations, specific results are obtained for various types of constraints, e.g., one single nonsmooth inequality, differentiable constraints modeled by polyhedral sets, finitely and infinitely many differentiable inequalities. The obtained conditions enable to detect calmness in a number of situations, where the standard criteria (via polyhedrality or the Aubin property) do not work. Their application in the framework of generalized differential calculus is explained and illustrated by examples associated with optimization and stability issues in connection with nonlinear complementarity problems or continuity of the value-at-risk.

description: Chemosensory protein 16 was identified in the hemolymph of Galleria mellonella as a protein with an amount increasing after oral infection with 10^3 CFU of Pseudomonas entomophila, and decreasing after infection with a higher dose (10^5 CFU) of bacteria. The expression of the CSP16 gene occurred in the fat body and in the gut and correlated with changes in the protein level in the hemolymph. The CSP16 protein inhibited P. entomophila growth in the concentration range from 0.15 to 6 nM. Additionally, the CSP16 protein showed bactericidal activity against P. entomophila, Bacillus thuringiensis, and Escherichia coli in the range of 2–18 μM, but only in the presence of protease inhibitors, otherwise it was degraded by extracellular proteases secreted by P. entomophila. We demonstrated that the bactericidal activity of CSP16 was related to its ability to perforate bacterial cellular membranes in a dose-dependent manner. The antimicrobial properties of this protein were also confirmed with the use of Atomic Force Microscopy, which showed significant changes in the topology of different bacterial cell surfaces. Finally, when CSP16 was injected in vivo into G. mellonella larvae one hour after infection with P. entomophila, more survivors were observed at particular time-points. Taking into account its immune properties and putative ability to bind bacteria-derived compounds, the possible function of CSP16 in the host-pathogen interaction is discussed.

description: We present a novel strategy to uncover the Galactic population of quiescent black holes (BHs). This is based on a new concept, the photometric mass function (PMF), which opens up the possibility of an efficient identification of dynamical BHs in large fields-of-view. This exploits the width of the disc Halpha emission line, combined with orbital period information. We here show that Halpha widths can be recovered using a combination of customized Halpha filters. By setting a width cut-off at 2200 km/s we are able to cleanly remove other Galactic populations of Halpha emitters, including ~99.9% of cataclysmic variables (CVs). Only short period (Porb<2.1 h) eclipsing CVs and AGNs will contaminate the sample but these can be easily flagged through photometric variability and, in the latter case, also mid-IR colours. We also describe the strategy of a deep (r=22) Galactic plane survey based on the concept of PMFs: HAWKs, the HAlpha-Width Kilo-deg Survey. We estimate that ~800 sqr deg are required to unveil ~50 new dynamical BHs, a three-fold improvement over the known population. For comparison, a century would be needed to produce an enlarged sample of 50 dynamical BHs from X-ray transients at the current discovery rate.

description: In the United States, the real estate tax continues to be the most important own-source local tax revenue. As a consequence, there is a vast practitioner literature about how a local real estate tax can be administered most fairly and inexpensively. The International Association of Assessing Officers has promulgated manuals, training, standards of practice, and statutory language that define and enable best assessment practice . Until 1982, the Governments Division of the US Census Bureau measured and reported the quality of residential property assessment by metropolitan area and state4 . Beyond these two important research enterprises, other public finance researchers have explored a wide variety of questions about the valuation mechanism that underlies application of local real estate taxation.

 PARALECTOTYPES EXAMINED: 2 ♀♀ (one glued to a cardboard stage, the other with head in a plastic vial pinned below specimen) (MZUF: Box 31): Oxyna Desv. / grandinata Rnd., ♀, Parma / 1650.
 CURRENT STATUS: valid species, as Campiglossa grandinata (Foote 1984: 74, White 1986: 160, Korneyev 1990: 450, Merz 1994: 47, Belcari et al. 1995b: 10, Norrbom et al. 1999: 110).
 REMARKS: Rondani (1870c: 131) described Oxyna grandinata without specifying the number, the sex or the length of the specimens, from material he had collected and also received from A. Garbiglietti, treating it within the subgenus Campiglossa Rondani, 1870. Korneyev (1990: 450) designated a lectotype (♀) and paralectotypes (2 ♀♀). Morge (1959b: 90) listed this nominal species under the generic name Scopicera, which O’Hara et al. (2011: 200) considered as an “unavailable name; treated under Oxyna Robineau-Desvoidy, 1830 ”.

description: We consider properties of periodic solutions of the differential-delay system, which models a laser with optical feedback. In particular, we describe a set of multipliers for these solutions in the limit of large delay. As a preliminary result, we obtain conditions for stability of an equilibrium of a generic differential-delay system with fixed large delay $tau$. We also show a connection between characteristic roots of the equilibrium and multipliers of the mapping obtained via the formal limit $tautoinfty$.

description: Quadrupole transition densities in neutron-rich nuclei in the vicinity of the neutron drip-line are calculated in the framework of the Random Phase Approximation. The continuum is treated by expansion in oscillator functions. We focus on the states which contribute to the usual Giant Quadrupole Resonance, and not on the low-lying strength which is also expected in such nuclei and whose collective character is still under debate. We find that, due to the large neutron skin in these nuclei, the isoscalar and isovector modes are in general strongly mixed. We further show that the transition densities corresponding to the GQR states can be reasonably well described by the collective model in terms of in phase and out of phase oscillations of neutron and proton densities which have different radii.

description: The dispersion relation for surface waves on the boundary between a fully saturated poroelastic medium and a vacuum is investigated numerically in the whole range of frequencies. A linear model of a two-component poroelastic medium similar to but simpler than the classical Biot's model is used. In the whole range of frequencies there exist two modes of surface waves corresponding to the classical Rayleigh and Stoneley waves. The numerical results for phase velocities, group velocities and attenuations of these waves are shown for different values of the bulk permeability coefficient.

description: These lecture notes are devoted to an overview of the modelling and the numerical analysis of surface waves in two-component saturated poroelastic media. This is an extension to the part of the lecture notes by K. Wilmanski (WIAS-Preprint No. 945) which is primarily concerned with the classical surface waves in single component media. We use the ''simple mixture model'' which is a simplification of the classical Biot's model for poroelastic media. Two interfaces are considered here: firstly the interface between a porous half space and a vacuum and secondly the interface between a porous halfspace and a fluid halfspace. For both problems we show how a solution can be constructed and a numerical solution of the dispersion relation can be found. We discuss the results for phase and group velocities and attenuations, and compare some of them to the high and low frequency approximations. For the interface porous medium/vacuum there exist in the whole range of frequencies two surface waves - a leaky Rayleigh wave and a true Stoneley wave. For the interface porous medium/fluid one more surface wave appears - a leaky Stoneley wave. For this boundary velocities and attenuations of the waves are shown in dependence on the surface permeability. The true Stoneley wave exists only in a limited range of this parameter. At the end we have a look on some results of other authors and a glance on a logical continuation of this work, namely the description of the structure and the acoustic behavior of partially saturated porous media.

description: We compare the dewetting behavior of liquid polymer films on silicon/silicon oxide wafers that have been coated with either Octadecyltrichlorosilane (OTS) or Dodecyltrichlorosilane (DTS). Our experiments show that the dewetting rates for DTS are significantly larger than for OTS. We also compare the profile of the rim that forms as the film dewets and find that it develops a spatially decaying oscillatory structure on the side facing the undisturbed film if an OTS coated wafer is used, but is monotonically decaying for DTS. We argue that for this situation only the friction coefficient can be different, suggesting that slippage plays a role in this transition. For the first time, we show here that this transition is in fact captured by a lubrication model that can be derived from the Navier-Stokes equations with a Navier-slip boundary condition at the liquid/solid interface, and accounts for large slip lengths.

description: We discuss effective models derived from a supersymmetric model whose mediation mechanism of supersymmetry (SUSY) breaking is namely mirage mediation. In this model, light higgsino mass, that is required by the natural realization of the electroweak scale, is achieved by the unification of the soft SUSY breaking parameters at the low scale. Besides, we find that extra Higgs fields are also possibly light in some cases. Then, the effective model is a two Higgs doublet model (2HDM) with higgsinos, and it is distinguishable with namely type-II 2HDM which is widely discussed. In this paper, we study the mass spectrum of SUSY particles and the extra Higgs fields, and summarize the phenomenology in the effective model. We survey the current experimental bounds from the LHC and the dark matter experiments as well as the flavor physics. Then, we point out the expected mass scale of the SUSY particles and reveal the future prospects for the direct and indirect searches. We also discuss the difference between our effective model and the 2HDM in the bottom-up approach.

description: This study examined the effect of consumer decision patterns on the organizational performance of selected LG outlets in Uyo metropolis, Akwa Ibom State, Nigeria. The inability of marketers and managers of LG outlets to properly understand their consumers’ buying behavior seem to crumble and retard their profits, sales volume, and decrease their customer base in the Uyo metropolis. A descriptive survey research design was adopted in which primary data were obtained through questionnaire administration. The study population consisted of all the customers and staff of LG outlets located at Ikot Ekpene Road, Abak Road, Aka Road, and Oron Road within Uyo metropolis in Akwa Ibom State, Nigeria. However, a total sample size of 30 respondents was selected using the purposive sampling technique. The researchers employed both descriptive and inferential statistics to analyze the collected data. The Pearson correlation analysis technique was also employed to analyze the data. The reported p-values were used to test the significance of the stated research hypotheses. The finding was that there is a significant effect of consumer choice on the sales volume of selected LG outlets in Uyo metropolis, Akwa Ibom State, Nigeria. Another finding revealed a significant effect of consumer choice on sales volume. Further discovery was that there is a significant effect of consumer choice on profitability. It was concluded that consumer buying behavior has a significant effect on the organizational performance of selected LG outlets in the Uyo metropolis, Akwa Ibom State, Nigeria. Recommendations were that LG outlets in the Uyo metropolis should conduct market research to properly understand their consumers’ buying behavior. The marketers of LG products should carefully explain products’ features, quality, and durability to consumers in order for them to make their choices. There is a need for customer follow-up after sales to sustain such customers, which in turn will increase their customer base. Marketers at different LG outlets in the Uyo metropolis should embark on aggressive marketing strategies to boost their sales volume

description: We consider a cosmological model with non-Gaussian initial perturbations, which in principle could be generated in non-standard inflationary scenarios with two or more scalar fields. In particular we focus our attention on the model proposed by Linde & Mukhanov (1997) perturbations are quadratic in a Gaussian field. These perturbations, if they exist, have to be observable as a non-Gaussian distribution of the CMB signal on the sky. In order to efficiently pick up the non-Gaussian signal in CMB maps of degree resolution, one can use Minkowski Functionals and peak statistics. Our paper contains the theoretical predictions of the properties for Minkowski Functionals and distributions of peaks of the CMB anisotropy in the model with "squared" Gaussian statistics. Likelihood comparison of the four-year COBE DMR data to this non-Gaussian model and the standard Gaussian model does not select any of them as most likely. We also suggest an efficient algorithm for fast simulation of CMB maps on the whole sky. Using a cylindrical partition of the sphere, we rewrite the spherical harmonics analysis as a Fourier transform in flat space, which makes the problem accessible to numerically advantageous FFT methods.

description: We propose a novel method utilizing stellar kinematic data to detect low-mass substructure in the Milky Way's dark matter halo. By probing characteristic wakes that a passing dark matter subhalo leaves in the phase space distribution of ambient halo stars, we estimate sensitivities down to subhalo masses $\sim 10^7\,M_\odot$ or below. The detection of such subhalos would have implications for dark-matter and cosmological models that predict modifications to the halo-mass function at low halo masses. We develop an analytic formalism for describing the perturbed stellar phase-space distributions, and we demonstrate through simulations the ability to detect subhalos using the phase-space model and a likelihood framework. Our method complements existing methods for low-mass subhalo searches, such as searches for gaps in stellar streams, in that we can localize the positions and velocities of the subhalos today.

description: We give an overview on the metric aspect of noncommutative geometry, especially the metric interpretation of gauge fields via the process of "fluctuation of the metric". Connes' distance formula associates to a gauge field on a bundle P equipped with a connection H a metric. When the holonomy is trivial, this distance coincides with the horizontal distance defined by the connection. When the holonomy is non trivial, the noncommutative distance has rather surprising properties. Specifically we exhibit an elementary example on a 2-torus in which the noncommutative metric d is somehow more interesting than the horizontal one since d preserves the S^1-structure of the fiber and also guarantees the smoothness of the length function at the cut-locus. In this sense the fiber appears as an object "smoother than a circle". As a consequence, from a intrinsic metric point of view developed here, any observer whatever his position on the fiber can equally pretend to be "the center of the world".

description: The first four gravitational wave events detected by LIGO were all interpreted as merging black hole binaries (BHBs), opening a new perspective on the study of such systems. Here we use our new population-synthesis code MOBSE, an upgraded version of BSE (Hurley et al. 2002), to investigate the demography of merging BHBs. MOBSE includes metallicity-dependent prescriptions for mass loss of massive hot stars. It also accounts for the impact of the electron-scattering Eddington factor on mass loss. We perform >10^8 simulations of isolated massive binaries, with 12 different metallicities, to study the impact of mass loss, core-collapse supernovae and common envelope on merging BHBs. Accounting for the dependence of stellar winds on the Eddington factor leads to the formation of black holes (BHs) with mass up to 65 Msun at metallicity Z~0.0002. However, most BHs in merging BHBs have masses <40 Msun. We find merging BHBs with mass ratios in the 0.1 - 1.0 range, even if mass ratios >0.6 are more likely. We predict that systems like GW150914, GW170814 and GW170104 can form only from progenitors with metallicity Z<=0.006, Z<=0.008 and Z<=0.012, respectively. Most merging BHBs have gone through a common envelope phase, but up to ~17 per cent merging BHBs at low metallicity did not undergo any common envelope phase. We find a much higher number of mergers from metal-poor progenitors than from metal-rich ones: the number of BHB mergers per unit mass is ~10^-4 Msun^-1 at low metallicity (Z = 0.0002 - 0.002) and drops to ~10^-7 Msun^-1 at high metallicity (Z ~ 0.02).

description: We study the statistics of the force felt by a particle in the class of spatially correlated distribution of identical point-like particles, interacting via a $1/r^2$ pair force (i.e. gravitational or Coulomb), and obtained by randomly perturbing an infinite perfect lattice. In the first part we specify the conditions under which the force on a particle is a well defined stochastic quantity. We then study the small displacements approximation, giving both the limitations of its validity, and, when it is valid, an expression for the force variance. In the second part of the paper we extend to this class of particle distributions the method introduced by Chandrasekhar to study the force probability density function in the homogeneous Poisson particle distribution. In this way we can derive an approximate expression for the probability distribution of the force over the full range of perturbations of the lattice, i.e., from very small (compared to the lattice spacing) to very large where the Poisson limit is recovered. We show in particular the qualitative change in the large-force tail of the force distribution between these two limits. Excellent accuracy of our analytic results is found on detailed comparison with results from numerical simulations. These results provide basic statistical information about the fluctuations of the interactions (i) of the masses in self-gravitating systems like those encountered in the context of cosmological N-body simulations, and (ii) of the charges in the ordered phase of the One Component Plasma.

description: Choosing the best hospitals or avoiding the worst hospitals is important to patients, physicians, and insurers. There is a wealth of publicly reported quality data to use in making those choices, but that data is presented in ways that may conceal important information. We develop three models of how individuals might use the available data in choosing a hospital and present a model that relies on a group-based alternative to the current reporting methods. We compare these four models on their ability to both predict hospital performance on quality and to identify the best and worst hospitals using three measures of patient safety calculated for California hospitals 1997-2006. We find that there are no clear winners in predicting the levels of quality, but we do find evidence that groupbased models may be better at identifying the worst hospitals.

description: Spiral arms have been observed in nearly a dozen protoplanetary discs in near-infrared scattered light and recently also in the sub-millimetre continuum. While one of the most compelling explanations is that they are driven by planetary or stellar companions, in all but one cases such companions have not yet been detected and there is even ambiguity on whether the planet should be located inside or outside the spirals. Here we use 3D hydrodynamic simulations to study the morphology of spiral density waves launched by embedded planets taking into account the vertical temperature gradient, a natural consequence of stellar irradiation. Our simulations show that the pitch angle of the spirals in thermally stratified discs is the lowest in the disc mid-plane and increases towards the disc surface. We combine the hydrodynamic simulations with 3D radiative transfer calculations to predict that the pitch-angle of planetary spirals observed in the near-infrared is higher than in the sub-millimetre. We also find that in both cases the spirals converge towards the planet. This provides a new powerful observational method to determine if the perturbing planet is inside our outside the spirals, as well as map the thermal stratification of the disc.

Electromagnetic Properties of the Delta(1232)

description: We calculate the electromagnetic moments and radii of the Delta(1232) in the nonrelativistic quark model, including two-body exchange currents. We show that two-body exchange currents lead to nonvanishing Delta and N-->Delta transition quadrupole moments even if the wave functions have no D-state admixture. The usual explanation based on the single-quark transition model involves D-state admixtures but no exchange currents. We derive a parameter- free relation between the N-->Delta transition quadrupole moment and the neutron charge radius: Q(N-->Delta) = r^2(neutron)/sqrt(2). Furthermore, we calculate the M1 and E2 amplitudes for the process photon + N -->Delta. We find that the E2 amplitude receives sizeable contributions from exchange currents. These are more important than the ones which result from D-state admixtures due to tensor forces between quarks if a reasonable quark core radius of about 0.6 fm is used. We obtain a ratio of E2/M1=-3.5%.

description: We report a study of magnetism and magnetic transitions of hexagonal ErMnO$_3$ single crystals by magnetization, specific heat and heat transport measurements. Magnetization data show that the $c$-axis magnetic field induces three magnetic transitions at 0.8, 12 and 28 T. The specific heat shows a peak at 2.2 K, which is due to a magnetic transition of Er$^{3+}$ moments. For low-$T$ thermal conductivity ($κ$), a clear dip-like feature appears in $κ(H)$ isotherm at 1--1.25 T for $H \parallel ab$; while in the case of $H \parallel c$, a step-like increase is observed at 0.5--0.8 T. The transition fields in $κ(H)$ are in good agreement with those obtained from magnetization, and the anomaly of $κ$ can be understood by a spin-phonon scattering scenario. The natures of magnetic structures and corresponding field-induced transitions at low temperatures are discussed.

description: We study the quantization of the noncommutative selfdual ϕ^3 model in 4 dimensions, by mapping it to a Kontsevich model. The model is shown to be renormalizable, provided one additional counterterm is included compared to the 2-dimensional case which can be interpreted as divergent shift of the field ϕ. The known results for the Kontsevich model allow to obtain the genus expansion of the free energy and of any n-point function, which is finite for each genus after renormalization. No coupling constant or wavefunction renormalization is required. A critical coupling is determined, beyond which the model is unstable. This provides a nontrivial interacting NC field theory in 4 dimensions.

description: We show that the quantum Hall wave functions for the ground states in the Jain series can be exactly expressed in terms of correlation functions of local vertex operators, V_n, corresponding to composite fermions in the n:th composite-fermion (CF) Landau level. This allows for the powerful mathematics of conformal field theory to be applied to the successful CF phenomenology. Quasiparticle and quasihole states are expressed as correlators of anyonic operators with fractional (local) charge, allowing a simple algebraic understanding of their topological properties that are not manifest in the CF wave functions.

description: Estimation of model parameters in a dynamic system can be significantly improved with the choice of experimental trajectory. For general, nonlinear dynamic systems, finding globally "best" trajectories is typically not feasible; however, given an initial estimate of the model parameters and an initial trajectory, we present a continuous-time optimization method that produces a locally optimal trajectory for parameter estimation in the presence of measurement noise. The optimization algorithm is formulated to find system trajectories that improve a norm on the Fisher information matrix. A double-pendulum cart apparatus is used to numerically and experimentally validate this technique. In simulation, the optimized trajectory increases the minimum eigenvalue of the Fisher information matrix by three orders of magnitude compared to the initial trajectory. Experimental results show that this optimized trajectory translates to an order of magnitude improvement in the parameter estimate error in practice.

description: The electronic structure of the helium atom in the magnetic field regime B=0-100a.u. is investigated, using a full configuration interaction approach which is based on a nonlinearly optimized anisotropic Gaussian basis set of one-particle functions. The corresponding generalized eigenvalue problem is solved for the magnetic quantum number M=-1 and for both even and odd z-parity as well as singlet and triplet spin symmetry. Accurate total electronic energies of the ground state and the first four excitations in each subspace as well as their one-electron ionization energies are presented as a function of the magnetic field. Additionally we present energies for electromagnetic transitions within the M=-1 subspace and between the M=-1 subspace and the M=0 subspace treated in a previous work. A complete table of wavelengths and field strengths for the detected stationary points is given.

Skyrme-Model $πNN$ Form Factor and Nucleon-Nucleon Interaction

description: We apply the strong $πNN$ form factor, which emerges from the Skyrme model, in the two-nucleon system using a one-boson-exchange (OBE) model for the nucleon-nucleon (NN) interaction. Deuteron properties and phase parameters of NN scattering are reproduced well. In contrast to the form factor of monopole shape that is traditionally used in OBE models, the Skyrme form factor leaves low momentum transfers essentially unaffected while it suppresses the high-momentum region strongly. It turns out that this behavior is very appropriate for models of the NN interaction and makes possible to use a soft pion form factor in the NN system. As a consequence, the $πN$ and the $NN$ systems can be described using the same soft $πNN$ form factor, which is impossible with the monopole.

description: Urban affordable housing planning and development is a challenging enterprise. Practitioners, which range from small neighborhood community development corporations to county-level agencies to nonprofit developers operating at the regional level, routinely solve problems involving multiple stakeholders, competing objectives, funding sources, production processes, strategies and outcome measures. Academic research addressing the design and evaluation of policies that address community concerns and generate significant social impacts is limited. Using surveys and in-depth interviews with affordable housing providers in the Pittsburgh metropolitan area, we describe current practices and organizational values and test hypotheses that address the relationships between organizational characteristics, neighborhood characteristics and residential real estate development choices and methods. These findings are used to formulate quantitative planning models that address two problems faced by providers: choice of parcels to develop in order to maximize the social benefit associated with low-income housing search, and choice of parcels to develop to maximize neighborhood-level benefits. We find substantial support for structured, prescriptive policy modeling that is evidence-based, value-focused and methodologically appropriate.
