description: A series of novel copper (II), cadmium (II), and silver (I) coordination frameworks, {[CuL2(H2O)2]·2(ClO4)·2H2O}n (1), {[CdL2(H2O)2]·2(ClO4)·2H2O}n (2), and [AgL·CF3SO3]n (3) based on 3,5-bis-(triazol-1-yl)pyridine(L), have been isolated and characterized by single-crystal X-ray diffraction. In 1 and 2, the bi-dentate L bridges neighboring CuII centers and CdII centers generating the one-dimensional (1D) double-chain cationic coordination polymer, in which lattice-free ClO4– and lattice water molecules are located between these neighboring 1D chains. In 3, these tri-dentate L bridge neighboring AgI centers, which construct the two-dimensional (2D) coordination framework. The terminal coordinated CF3SO3– anions are decorated along the side of the 2D framework. Further, 1 also presents the novel example of cationic triazole-copper (II) coordination polymer for effectively capturing anion pollutants Cr2O72– in the water solutions. The solid-state luminescent properties of L and coordination polymers 2–3 were also investigated.

description: In the context of large scale structure formation, clusters of galaxies are located at the nodes of the cosmic web, and continue to accrete galaxies and groups along filaments. They show sometimes a very large extension and a preferential direction. Brightest cluster galaxies (BCGs) are believed to grow through the accretion of many small galaxies, and their structural properties are expected to vary with redshift. In some cases BCGs show an orientation comparable to that of the cluster to which they belong. We analyse the morphological properties of 38 BCGs from the DAFT/FADA and CLASH surveys and compare the position angles of their major axes to the direction of the cluster elongation at Mpc scale. The morphological properties of the BCGs were studied by applying the GALFIT software to HST images and fitting the light distribution with one or two Sersic laws, or with a Nuker plus a Sersic law. The cluster elongations were estimated by computing density maps of red sequence galaxies. The analysis of the 38 BCGs shows that in 11 cases a single Sersic law is sufficient to account for the surface brightness, while for all the other clusters two laws are necessary. For the outer Sersic component, the effective radius increases with decreasing redshift, and the effective surface brightness decreases with effective radius, following the Kormendy law. An agreement between the major axis of the BCG and the cluster elongation at large scale within +-30 deg is found for 12 clusters out of the 21 for which both PAs can be defined. The variation with redshift of the effective radius of the outer Sersic component agrees with the growing of BCGs by accretion of smaller galaxies from z=0.9 to 0.2. The directions of the elongations of BCGs and of their host clusters and large scale structures agree for 12 objects out of 21, implying that a larger sample is necessary to reach more definite conclusions.

description: We demonstrate that the linewidth of the field emission resonance (FER) observed on the surface of MoS2 using scanning tunneling microscopy can vary by up to one order of magnitude with an increase in the electric field. This unusual phenomenon originates from quantum trapping, where the electron relaxed from the resonant electron in the FER is momentarily trapped in the potential well on the MoS2 surface. Because the relaxed electron and the resonant electron have the same spin and the action of the Pauli exclusion principle, the lifetimes of the resonant electrons can be substantially prolonged when the relaxed electrons engage in the resonance trapping. The linewidth of the FER is thus shrunk considerably to as narrow as 12 meV. Moreover, it was found that the valley intensities around the FER are zero, indicating that MoS2 has an energy gap above the vacuum level. By using the energies of FERs, the potential of the band bending in the MoS2 interior can be measured precisely.

description: Exceptional points in non-Hermitian systems have recently been shown to possess nontrivial topological properties, and to give rise to many exotic physical phenomena. However, most studies thus far have focused on isolated exceptional points or one-dimensional lines of exceptional points. Here, we substantially expand the space of exceptional systems by designing two-dimensional surfaces of exceptional points, and find that symmetries are a key element to protect such exceptional surfaces. We construct them using symmetry-preserving non-Hermitian deformations of topological nodal lines, and analyze the associated symmetry, topology, and physical consequences. As a potential realization, we simulate a parity-time-symmetric 3D photonic crystal and indeed find the emergence of exceptional surfaces. Our work paves the way for future explorations of systems of exceptional points in higher dimensions.

description: We show that Barkhausen noise in two-dimensional disordered ferromagnets with extended domain walls is characterized by the avalanche size exponent $τ_s =1.54$ at low disorder. With increasing disorder the characteristic domain size is reduced relative to the system size due to nucleation of new domains and a dynamic phase transition occurs to the scaling behavior with $τ_s=1.30$. The exponents decrease at finite driving rate. The results agree with recently observed behavior in amorphous Metglas and Fe-Co-B ribbons when the applied anisotropic stress is varied.

description: This article deals with the problems associated with online international trade, i.e. e-commerce, within the EU. The authors examine the potential barriers to cross-border online selling and online buying with the focus on problems related to standards. The problems associated with interoperability and labelling can be seen as clearly related to standards. Using data from the flash Eurobarometer (413) survey, logit and ordered logit regressions are estimated. Interoperability problems, when selling online, are more frequently reported by wholesale firms and those in the information and communication sector. Firms who are part of an international group are more likely to sell online and have slightly fewer problems with interoperability. The majority of the firms in the sample believe that common rules of e-commerce within the EU could be beneficial for their online business. This is especially true for those reporting problems with interoperability, different labelling or copyright issues. This then provides justification for the EU to adopt such rules.

description: The ERIC Forum responds herewith to the request, by the ERAC WG, to address four questions on future ERA Objectives and ERA Priorities as a follow up of the discussion on the previous draft on the “Options for a New Narrative on the Future of ERA” which is now available as a final version (8 October). The questions will be addressed in the Stakeholders hearing planned on 29 October 2019 and are based on a synthetic document proposed to us by the ERAC WG, describing three ERA Objectives towards a really functional ERA and four wide Priorities designed to achieve the three objectives. Objectives and Priorities should be in line with the renewed ERA Paradigm, including possible legislative or soft regulatory measures. The last question specifically addresses which concrete initiatives should be launched (e.g. the ERA lighthouses).

description: In this paper, we introduce STOAViz, a visual analytics tool for analyzing the saturated thickness of the Ogallala aquifer. The saturated thicknesses are monitored by sensors integrated on wells distributed on a vast geographic area. Our analytics application also captures the trends and patterns (such as average/standard deviation over time, sudden increase/decrease of saturated thicknesses) of water on an individual well and a group of wells based on their geographic locations. To highlight the usefulness and effectiveness of STOAViz, we demonstrate it on the Southern High Plains Aquifer of Texas. The work was developed using feedback from experts at the water resource center at a university. Moreover, our technique can be applied on any geographic areas where wells and their measurements are available.
Relativity in space-times with short-distance structure governed by an observer-independent (Planckian) length scale

description: I show that it is possible to formulate the Relativity postulates in a way that does not lead to inconsistencies in the case of space-times whose short-distance structure is governed by an observer-independent length scale. The consistency of these postulates proves incorrect the expectation that modifications of the rules of kinematics involving the Planck length would necessarily require the introduction of a preferred class of inertial observers. In particular, it is possible for every inertial observer to agree on physical laws supporting deformed dispersion relations of the type $E^2- c^2 p^2- c^4 m^2 + f(E,p,m;L_p)=0$, at least for certain types of $f$.

Our calculations have shown the formation of a stable coorbital with the planet ring is possible for Kepler-16 and Kepler-35 systems. In Kepler-34 system, significant eccentricities of the orbits of the binary and planets can to prevent the formation of such a structure. Detection circumbinary annular structures in observations of systems binary stars can be evidence of the existence of planets, retaining coorbital rings from dust and planetesimals.

description: Low-energy excitations in spin 1/2 antiferromagnetic Heisenberg spin ladders are studied by bosonization and gauge theoretical description. It is explicitly shown that zero modes in the bosonization play an essentially important role. Low-energy excitations in the 2-leg system is described by spin triplet Majorana fermions, and in the 3-leg case spin excitations on the top and bottom ladders are described by two massless scalar fields. It is predicted that if inter-ladder interaction between the top and bottom chains is introduced, a phase transition occures at some critical coupling and the system acquires an energy gap.

description: As opposed to purely molecular systems where electron dynamics proceed only through intramolecular processes, weakly bound complexes such as He droplets offer an environment where local excitations can interact with neighbouring embedded molecules leading to new intermolecular relaxation mechanisms. Here, we report on a new decay mechanism leading to the double ionization of alkali dimers attached to He droplets by intermolecular energy transfer. From the electron spectra, the process is similar to the well-known shake-off mechanism observed in double Auger decay and single-photon double ionization, however, in this case, the process is dominant, occurring with efficiencies equal to, or greater than, single ionization by energy transfer. Although an alkali dimer attached to a He droplet is a model case, the decay mechanism is relevant for any system where the excitation energy of one constituent exceeds the double ionization potential of another neighbouring molecule. The process is, in particular, relevant for biological systems, where radicals and slow electrons are known to cause radiation damage

description: Recent advances in deep learning motivate the use of deep neural networks in Internet-of-Things (IoT) applications. These networks are modelled after signal processing in the human brain, thereby leading to significant advantages at perceptual tasks such as vision and speech recognition. IoT applications, however, often measure physical phenomena, where the underlying physics (such as inertia, wireless signal propagation, or the natural frequency of oscillation) are fundamentally a function of signal frequencies, offering better features in the frequency domain. This observation leads to a fundamental question: For IoT applications, can one develop a new brand of neural network structures that synthesize features inspired not only by the biology of human perception but also by the fundamental nature of physics? Hence, in this paper, instead of using conventional building blocks (e.g., convolutional and recurrent layers), we propose a new foundational neural network building block, the Short-Time Fourier Neural Network (STFNet). It integrates a widely-used time-frequency analysis method, the Short-Time Fourier Transform, into data processing to learn features directly in the frequency domain, where the physics of underlying phenomena leave better foot-prints. STFNets bring additional flexibility to time-frequency analysis by offering novel nonlinear learnable operations that are spectral-compatible. Moreover, STFNets show that transforming signals to a domain that is more connected to the underlying physics greatly simplifies the learning process. We demonstrate the effectiveness of STFNets with extensive experiments. STFNets significantly outperform the state-of-the-art deep learning models in all experiments. A STFNet, therefore, demonstrates superior capability as the fundamental building block of deep neural networks for IoT applications for various sensor inputs.

An abundance analysis for four Red Horizontal Branch Stars in the extremely metal rich globular cluster NGC 6528

description: We present the results of the first analysis of high dispersion spectra of four red HB stars in the metal rich globular cluster NGC 6528, located in Baade's Window. We find that the mean [Fe/H] for NGC 6528 is +0.07+-0.01 dex (error of the mean), with a star-to-star scatter of sigma = 0.02 dex (4 stars), although the total error is likely to be larger (~0.1 dex) due to systematic errors related to the effective temperature scale and to model atmospheres. This metallicity is somewhat larger than both the mean abundance in the galactic bulge found by McWilliam & Rich (1994) and that found in our previous paper for NGC 6553. However, we find that the spectra of clump stars in NGC 6528 and NGC 6553 are very similar each other, the slightly different metal abundances found being possibly due to the different atmospheric parameters adopted in the two analyses. For NGC 6528 we find excesses for the alpha-process elements Si and Ca ([Si/Fe]=+0.4 and [Ca/Fe]=+0.2), whereas Mn is found to be underabundant ([Mn/Fe]=-0.4). We find a solar abundance of O; however this is somewhat uncertain due to the dependence of the O abundance on the adopted atmospheric parameters and to coupling between C and O abundances in these cool, metal-rich stars. Finally, we find large Na excesses ([Na/Fe]~ +0.4) in all stars examined. Since the present analysis is based on higher quality material, we propose to revise our previous published metal abundance for NGC 6553 to [Fe/H]=$0.06+-0.15.

description: Studies of the human cochlea are particularly challenging due its exceptional vulnerability and surrounding hard bone. Swift fixation and mild decalcification are necessary to maintain its structural integrity and preserve antigenicity. Such procedures may allow immunohistochemistry, gene analyses, and molecular imaging using super resolution illumination microscopy (SR-SIM) with nanometer resolution. This presentation updates recent studies of the human cochlear microanatomy and immunohistochemistry by our laboratory, discussed in the context of current and past anatomic findings and the available literature. Human studies are necessary, and there are intriguing discrepancies compared with experimental animal studies, highlighting that “men are not simply big mice.” The results may improve our understanding of the function of the human hearing organ, the diseases related to it, and how this better understanding can be extended to impact future treatment. The first human inner ear gene therapy trials are in progress, and the accessibility of human cochlear tissue for future stem cell treatment and gene transfer needs further elucidation.

description: We study the tunneling dynamics of dopant-induced hole polarons which are self-localized by electron-phonon coupling in a two-dimensional antiferro- magnet. Our treatment is based on a path integral formulation of the adia- batic approximation, combined with many-body tight-binding, instanton, con- strained lattice dynamics, and many-body exact diagonalization techniques. Our results are mainly based on the Holstein-$tJ$ and, for comparison, on the Holstein-Hubbard model. We also study effects of 2nd neighbor hopping and long-range electron-electron Coulomb repulsion. The polaron tunneling dynamics is mapped onto an effective low-energy Hamiltonian which takes the form of a fermion tight-binding model with occupancy dependent, predominant- ly 2nd and 3rd neighbor tunneling matrix elements, excluded double occupan- cy, and an effective intersite charge interactions. Antiferromagnetic spin correlations in the original many-electron Hamiltonian are reflected by an attractive contribution to the 1st neighbor charge interaction and by Berry phase factors which determine the signs of effective polaron tunneling ma- trix elements. In the two-polaron case, these phase factors lead to polaron pair wave functions of either $d_{x^2-y^2}$-wave symmetry or p-wave symme- try with zero and nonzero total pair momentum, respectively. Implications for the doping dependent isotope effect, pseudo-gap and Tc of a superconduc- ting polaron pair condensate are discussed/compared to observed in cuprates.

description: The available R-matrix parametrization of experimental data on the excitation functions for the elastic and inelastic p-Be7 scattering at the collision energies up to 3.4 MeV is used to generate the corresponding partial-wave cross sections in the states with J^pi=0+. Thus obtained data are considered as experimental partial cross sections and are fitted using the semi-analytic two-channel Jost matrix with proper analytic structure and some adjustable parameters. Then the spectral points are sought as zeros of the Jost matrix determinant (which correspond to the S-matrix poles) at complex energies. The correct analytic structure makes it possible to calculate the fitted Jost matrix on any sheet of the Riemann surface whose topology involves not only the square-root but also the logarithmic branching caused by the Coulomb interaction. In this way, two overlapping 0+ resonances at the excitation energies ~1.79 MeV and ~1.96 MeV have been found.

Using focussed beam Bragg spectroscopy, we locally probe atoms in the central region of a harmonically trapped cloud where the density is nearly uniform, enabling measurements of the dynamic structure factor for a range of temperatures both below and above the superfluid transition. Applying sum-rules to the measured Bragg spectra, we resolve the characteristic behaviour of the universal contact parameter, ${\cal C}$, across the superfluid transition. We also employ a recent theoretical result for the kinetic (second-moment) sum-rule to obtain the internal energy of gases at unitarity.

description: Current guidelines recommend that, when prescribing opioids, providers use urine drug testing (UDT) for harm reduction. Objective: To identify whether Medicaid beneficiaries in Nevada at increased risk for opioid misuse received UDT. Methods: We used Nevada Medicaid claims data (2017–2018) to describe UDT among three samples: opioid naïve patients (N = 11,326), opioid naïve patients with a second follow-up prescription (N = 8,910), and long-term opioid patients (N = 19,173). Predictors of opioid misuse include past diagnoses of mental health and substance use, demographic characteristics and potentially risky behaviors. Outcomes include receiving UDT prior to opioid prescription among the two naïve samples and within six months for the long-term sample. We report predicted probabilities (PP) from logistic regressions and hazard ratios (HR) and Kaplan-Meier curves. Results: A small percentage of patients received UDT (naïve sample: 2.5%; naïve with a second follow-up prescription sample: 3.5%; long-term sample: 9.9%). Adults with alcohol disorders and other substance use disorders had the highest PP of UDT, among both the naïve (alcohol related disorder: 3.1%; other substance use disorder: 7.7%) and the naïve with a second follow-up prescription (alcohol related disorder: 4.1%; other substance use disorder: 11.7%) samples. Among the long-term sample, similar predictors were significant. Conclusions: Although there was an association between having risk factors for opioid misuse (e.g. past alchohol disorders and other substance use disorder diagnoses) and receiving UDT, the percentage of patients who received UDT was unexpectedly low, pointing to the need to increase guideline adherence and implementation among providers who prescribe opioids.

description: The response function of domain growth processes, and in particular the violation of the fluctuation-dissipation theorem, are studied both analytically and numerically. In the asymptotic limit of large times, the fluctuation-dissipation ratio $X$, which quantifies this violation, tends to one if $C>m^2$ and to zero if $C2$, and as $\ln (L(t))/L(t)$ for $d=2$. Numerical results confirming this analysis are presented.

description: In big data era, the collected data usually contains rich information and hidden knowledge. Utility-oriented pattern mining and analytics have shown a powerful ability to explore these ubiquitous data, which may be collected from various fields and applications, such as market basket analysis, retail, click-stream analysis, medical analysis, and bioinformatics. However, analysis of these data with sensitive private information raises privacy concerns. To achieve better trade-off between utility maximizing and privacy preserving, Privacy-Preserving Utility Mining (PPUM) has become a critical issue in recent years. In this paper, we provide a comprehensive overview of PPUM. We first present the background of utility mining, privacy-preserving data mining and PPUM, then introduce the related preliminaries and problem formulation of PPUM, as well as some key evaluation criteria for PPUM. In particular, we present and discuss the current state-of-the-art PPUM algorithms, as well as their advantages and deficiencies in detail. Finally, we highlight and discuss some technical challenges and open directions for future research on PPUM.

description: This paper explores properties of the instantaneous ergo surface of a Kerr black hole. The surface area is evaluated in closed form. In terms of the mass ($m$) and angular velocity ($a$), to second order in $a$, the area of the ergo surface is given by $16 πm^2 + 4 πa^2$ (compared to the familiar $16 πm^2 - 4 πa^2$ for the event horizon). Whereas the total curvature of the instantaneous event horizon is $4 π$, on the ergo surface it ranges from $4 π$ (for $a=0$) to 0 (for $a=m$) due to conical singularities on the axis ($θ=0,π$) of deficit angle $2 π(1-\sqrt{1-(a/m)^2})$. A careful application of the Gauss-Bonnet theorem shows that the ergo surface remains topologically spherical. Isometric embeddings of the ergo surface in Euclidean 3-space are defined for $0 \leq a/m \leq 1$ (compared to $0 \leq a/m \leq \sqrt{3}/2$ for the horizon).

description: We use the wide-used \textsf{Einstein Toolkit} to solve the Einstein constraints and then simulate the expansion of primordial black hole lattices (PBHLs) with different value of $f_{\mathrm{PBH}}$ and $m_{\mathrm{PBH}}$. We find that $f_{\mathrm{PBH}}$ plays an important role during the evolution of PBHLs. Since the motion of primordial black holes (PBHs) caused by the expansion of PBHLs occurs at speeds close to that of light, we expect the emission of gravitational waves (GWs) during the expansion of PBHLs. We use both analytical estimates and numerical simulations to cross check the production of GWs in expanding PBHLs.

description: (Abridged) This paper is the fourth of a series reporting the results of the ATESP 1.4 GHz radio survey. The survey covers a region of ~26 sq. degrees at decl. -40 degr. and has produced a catalogue of 2967 radio sources down to ~0.5 mJy (6sigma). In this paper we present the optical identifications over a 3 sq. degr. region of the public ESO Imaging Survey. In this region deep photometry and 95% complete object catalogues in the I band are available down to I~22.5. These data allowed us to identify 57% of the ATESP sources present in the region (219/386). For a magnitude limited sample of 70 identified sources with I<19.0 we have obtained spectroscopy at the ESO 3.6 m telescope. This data allowed us to get redshifts and spectral classification for all sources (except one). From the analysis of the spectroscopic sample we find that the composition of the faint radio population abruptly changes going from mJy to sub-mJy fluxes: the early type galaxies largely dominate the mJy population (60%), while star forming processes become important in the sub-mJy regime. Starburst and post-starburst galaxies go from 13% at S>1 mJy to 39% at S<1 mJy. Nevertheless, at sub-mJy fluxes, early type galaxies still constitute a significant fraction (25%) of the whole population. We also show that, due to the distribution of radio to optical ratios, sub-mJy samples with fainter spectroscopic follow-ups should be increasingly sensitive to the population of early type galaxies, while a larger fraction of star-forming galaxies would be expected in microJy samples. We compare our results with others obtained from studies of sub-mJy samples and we show how the existing discrepancies can be explained in terms of selection effects.

description: We investigate exact eigenstates of tight-binding models on the planar rhombic Penrose tiling. We consider a vertex model with hopping along the edges and the diagonals of the rhombi. For the wave functions, we employ an ansatz, first introduced by Sutherland, which is based on the arrow decoration that encodes the matching rules of the tiling. Exact eigenstates are constructed for particular values of the hopping parameters and the eigenenergy. By a generalized ansatz that exploits the inflation symmetry of the tiling, we show that the corresponding eigenenergies are infinitely degenerate. Generalizations and applications to other systems are outlined.

description: This paper is a pragmatic study of the speech act of implicit complimenting among Jordanian people. The researcher follows the ethnomethodological approach in order to identify the construction and organization of such a speech act. Such an approach renders the speech act of implicit compliment as an undivided, integral part of the discourse in which it occurs. Adopting this orientation enables the researcher to focus on the motives behind choosing an implicit compliment instead of an explicit one at a specific time of the discourse. The results of the study show that implicit compliments are different from explicit ones and that such a speech act belongs to a different category. The study also shows that implicit compliments convey many interactional functions that serve the speaker and the addressee and that some functions serve them both.

description: Reservoir models are numerical representations of the subsurface petrophysical properties such as porosity, volume of minerals and fluid saturations. These are often derived from elastic models inferred from seismic inversion in a two-step approach: first, seismic reflection data are inverted for the elastic properties of interest (such as density, P-wave and S-wave velocities); these are then used as constraining properties to model the subsurface petrophysical variables. The sequential approach does not ensure a proper propagation of uncertainty throughout the entire geo-modelling workflow as it does not describe a direct link between the observed seismic data and the resulting petrophysical models. Rock physics models link the two domains. We propose to integrate seismic and rock physics modelling into an iterative geostatistical seismic inversion methodology. The proposed method allows the direct inference of the porosity, volume of shale and fluid saturations by simultaneously integrating well-logs, seismic reflection data and rock physics model predictions. Stochastic sequential simulation is used as the perturbation technique of the model parameter space, a calibrated facies-dependent rock physics model links the elastic and the petrophysical domains and a global optimizer based on cross-over genetic algorithms ensures the convergence of the methodology from iteration to iteration. The method is applied to a 3D volume extracted from a real reservoir dataset of a North Sea reservoir and compared to a geostatistical seismic AVA.

description: An experimental search for variation in the fundamental coupling constants is strongly motivated by modern high-energy physics theories. Comparison of quasar absorption line spectra with laboratory spectra provides a sensitive probe for variability of the fine structure constant, alpha, over cosmological time-scales. We have previously developed and applied a new method providing an order of magnitude gain in precision over previous optical astrophysical constraints. Here we extend that work by including new quasar spectra of damped Lyman-alpha absorption systems. We also re-analyse our previous lower redshift data and confirm our initial results. The constraints on alpha come from simultaneous fitting of absorption lines of subsets of the following species: Mg I, Mg II, Al II, Al III, Si II, Cr II, Fe II, Ni II and Zn II. We present a detailed description of our methods and results based on an analysis of 49 quasar absorption systems (towards 28 QSOs) covering the redshift range 0.5 < z < 3.5. There is statistical evidence for a smaller alpha at earlier epochs: da/a = (-0.72 +/- 0.18) * 10^{-5}. The new and original samples are independent but separately yield consistent and significant non-zero values of da/a. We summarise the results of a thorough investigation of systematic effects published in a companion paper. The value we quote above is the raw value, not corrected for any of these systematic effects. The only significant systematic effects so far identified, if removed from our data, would lead to a more significant deviation of da/a from zero.
