description: During observations with RXTE we discovered two simultaneous kHz QPOs near 500 Hz and 860 Hz in the Z source Cyg X-2. In the X-ray color-color diagram and hardness-intensity diagram (HID) a clear Z track was traced out. A single kHz QPO peak was detected at the left end of the horizontal branch (HB) of the Z track, with a frequency of 731+/-20 Hz and an amplitude of 4.7+0.8-0.6 % rms in the energy band 5.0-60 keV. Further to the right on the HB, at somewhat higher count rates, an additional peak at 532+/-43 Hz was detected with an rms amplitude of 3.0+1.0-0.7 %. When the source moved down the HB, thus when the inferred mass accretion rate increased, the frequency of the higher-frequency QPO increased to 839+/-13 Hz, and its amplitude decreased to 3.5+0.4-0.3 % rms. The higher-frequency QPO was also detected on the upper normal branch (NB) with an rms amplitude of 1.8+0.6-0.4 % and a frequency of 1007+/-15 Hz; its peak width did not show a clear correlation with inferred mass accretion rate. The lower-frequency QPO was most of the time undetectable, with typical upper limits of 2 % rms, no conclusion on how this QPO behaved with mass accretion rate can be drawn. If the peak separation between the QPOs is the neutron star spin frequency (as required in some beat-frequency models) then the neutron star spin period is 2.9+/-0.2 ms (346+/-29 Hz).

description: Tuning the charge carrier density of two-dimensional (2D) materials by incorporating dopants into the crystal lattice is a challenging task. An attractive alternative is the surface transfer doping by adsorption of molecules on 2D crystals, which can lead to ordered molecular arrays. However, such systems, demonstrated in ultra-high vacuum conditions (UHV), are often unstable in ambient conditions. Here we show that air-stable doping of epitaxial graphene on SiC - achieved by spin-coating deposition of 2,3,5,6-tetrafluoro-tetracyano-quino-dimethane (F4TCNQ) incorporated in poly (methyl-methacrylate) - proceeds via the spontaneous accumulation of dopants at the graphene-polymer interface and by the formation of a charge-transfer complex that yields low-disorder, charge-neutral graphene with carrier mobilities ~70,000 cm2/Vs at cryogenic temperatures. The assembly of dopants on 2D materials assisted by a polymer matrix, demonstrated by spin coating wafer-scale substrates in ambient conditions, opens up a scalable technological route towards expanding the functionality of 2D materials.

description: States on the Coulomb branch of N=4 super-Yang-Mills theory are studied from the point of view of gauged supergravity in five dimensions. These supersymmetric solutions provide examples of consistent truncation from type IIB supergravity in ten dimensions. A mass gap for states created by local operators and perfect screening for external quarks arise in the supergravity approximation. We offer an interpretation of these surprising features in terms of ensembles of brane distributions.

description: Combining classical electrodynamics and density functional theory (DFT) calculations, we develop a general and rigorous theoretical framework that describes the energetics of metal surfaces under high electric fields. We show that the behavior of a surface atom in the presence of an electric field can be described by the polarization characteristics of the permanent and field-induced charges in its vicinity. We use DFT calculations for the case of a W adatom on a W{110} surface to confirm the predictions of our theory and quantify its system-specific parameters. Our quantitative predictions for the diffusion of W-on-W{110} under field are in good agreement with experimental measurements. This work is a crucial step towards developing atomistic computational models of such systems for long-term simulations.

description: The use of extra dimensional scenarios as models for neutrino mass affects many low energy observables. We consider the implications of virtual bulk neutrinos in precision experiments of the anomalous magnetic moments of the muon and the electron. We consider neutrino models in factorizable geometry of the type M_4 x T as well as the sliced AdS_5 non-factorizable geometry. In both geometries we find finite contributions to g-2 after summing over the KK excitations of the bulk neutrinos. In the case of Randall-Sundrum geometry, we find that the muon experiment is approaching the precision necessary to probe these models.

description: We carry out simulations using a multiphase transport (AMPT) model to describe the observed flow signatures in $\sqrt{s_{NN}}=2.76$ TeV Pb-Pb collisions. Especially, we calculate the flow fluctuations of $v_2$ in terms of cumulant ratios and the standardized skewness. Based on event-by-event AMPT simulations, we study the linear and cubic response relation between $v_2$ and $\varepsilon_2$. We found that the observed response relation is compatible to what has been noticed in hydrodynamic modelings, with similar dependence on shear viscosity. Besides, this response relation is not sensitive to nonflow effects.

description: The study of high contrast imaged brown dwarfs and exoplanets depends strongly on evolutionary models. To estimate the mass of a directly imaged substellar object, its extracted photometry or spectrum is used and adjusted with model spectra together with the estimated age of the system. These models still need to be properly tested and constrained. HD 4747B is a brown dwarf close to the H burning mass limit, orbiting a nearby, solar-type star and has been observed with the radial velocity method over almost two decades now. Its companion was also recently detected by direct imaging, allowing a complete study of this particular object. We aim to fully characterize HD 4747B by combining a well constrained dynamical mass and a study of its observed spectral features in order to test evolutionary models for substellar objects and characterize its atmosphere. We combine the radial velocity measurements of HIRES and CORALIE taken over two decades and high contrast imaging of several epochs from NACO, NIRC2 and SPHERE to obtain a dynamical mass. From the SPHERE data we obtain a low resolution spectrum of the companion from Y to H band, as well as two narrow band-width photometric measurements in the K band. A study of the primary star allows in addition to constrain the age of the system as well as its distance. Thanks to the new SPHERE epoch and NACO archival data combined with previous imaging data and high precision radial velocity measurements, we have been able to derive a well constrained orbit. We derive a dynamical mass of mB=70.0$\pm$1.6 MJup which is higher than a previous study, but in better agreement with the models. By comparing the object with known brown dwarfs spectra, we derive a spectral type of L9 and an effective temperature of 1350$\pm$50 K. With a retrieval analysis we constrain the oxygen and carbon abundances and compare them with the ones from the HR 8799 planets.

description: Parity violating (PV) contributions due to interference between $γ$ and $Z^0$ exchange are calculated for pion electroproduction off the nucleon. A phenomenological model with effective Lagrangians is used to determine the resulting asymmetry for the energy region between threshold and $Δ(1232)$ resonance. The $Δ$ resonance is treated as a Rarita-Schwinger field with phenomenological $N Δ$ transition currents. The background contributions are given by the usual Born terms using the pseudovector $πN$ Lagrangian. Numerical results for the asymmetry are presented.

description: We study the stochastic dynamics of a particle in a periodically driven potential. For atomic ions trapped in radio-frequency Paul traps, noise heating and laser cooling typically act slowly in comparison with the unperturbed motion. These stochastic processes can be accounted for in terms of a probability distribution defined over the action variables, which would otherwise be conserved within the regular regions of the Hamiltonian phase space. We present a semiclassical theory of low-saturation laser cooling applicable from the limit of low-amplitude motion to large-amplitude motion, accounting fully for the time-dependent and anharmonic trap. We employ our approach to a detailed study of the stochastic dynamics of a single ion, drawing general conclusions regarding the nonequilibrium dynamics of laser-cooled trapped ions. We predict a regime of anharmonic motion in which laser cooling becomes diffusive (i.e., it is equally likely to cool the ion as it is to heat it), and can also turn into effective heating. This implies that a high-energy ion could be easily lost from the trap despite being laser cooled; however, we find that this loss can be counteracted using a laser detuning much larger than Doppler detuning.

description: A key goal of the Event Horizon Telescope is to observe the shadow cast by a black hole. Recent simulations have shown that binary black holes, the progenitors of gravitational waves, present shadows with fractal structure. Here we study the binary shadow structure using techniques from nonlinear dynamics, recognising shadows as exit basins of open Hamiltonian dynamical systems. We apply a recently developed numerical algorithm to demonstrate that parts of the Majumdar-Papapetrou binary black hole shadow exhibit the Wada property: any point of the boundary of one basin is also on the boundary of at least two additional basins. We show that the algorithm successfully distinguishes between the fractal and regular (i.e., non-fractal) parts of the binary shadow.

description: Introduction: Autoimmune pancreatitis (AIP) mainly manifests in two distinct forms with different clinical, serological and prognostic characteristics. Previous studies indicated a higher risk of malignancy in AIP patients compared with the general population. However, a direct comparison of cancer incidence in AIP patients with controls from the general population has not been conducted yet. Methods and analysis: This is an international, multicentre, retrospective study on patients diagnosed with AIP after 2005. Retrospective data regarding demography, AIP characteristics and cancer incidence will be extracted from the medical files of AIP patients. The primary outcome is the standardised incidence ratio of any first invasive cancer after AIP diagnosis compared with the general population. The expected number of cancers in the general population will be determined using the ‘Cancer Incidence in Five Continents Volume XI’ registry. Secondary outcomes are the prevalence of all cancer diagnoses within 12 months prior to AIP diagnosis and AIP features associated with a cancer diagnosis. Ethics and dissemination: This study was approved by the ethics committees of the autoimmune pancreatitis, pancreatic and extrapancreatic cancer (AIPPEAR) core group centres (Halle (Saale), Germany; Aalborg, Denmark; Tartu, Estonia; Munich, Germany; Göttingen, Germany; Maribor, Slovenia, with the following reference numbers: 2023–204, 2023–0 29 953, 382 /T-3, 24–0768, 9/7/23, UKC-MB-KME 59/23, respectively). Where required, the study protocol will be reviewed and approved by the ethics committees of participating centres in compliance with local regulations. Data will be stored in an electronic case report form within REDCap. In this context, the AIPPEAR core group will share joint responsibility for the data. All results from this study will be submitted to international, peer-reviewed journals and presented at international conferences.

description: We perform the quantization of a massive particle propagating on AdS_5. We use the twistor formulation in which the action can be brought into a quadratic form. We construct the BRST operator which commutes with AdS_5 isometries forming SU(2,2). The condition of a consistent BRST quantization requires that the AdS energy E is quantized in units of the AdS_5 radius R, E=\frac{1}{2R}(N_a +N_b+4), with N_a, N_b being some non-negative integers. We also argue that the mass operator will be identified with the moduli of the U(1) central extension Z of the SU(2,2|4) algebra in the supersymmetric case. The spectrum of physical states with vanishing ghost number contains a particular subset of `massless' SU(2,2) multiplets (including the bosonic part of the `novel short' supermultiplets). We hope that our results will help to quantize also the string on AdS_5.

description: Evaporation kinetics of pendant droplets is an area of immense importance in several applications in addition to possessing rich fluid and thermal transport physics. The present article experimentally and analytically sheds insight into the augmented evaporation dynamics of paramagnetic pendent droplets in the presence of a magnetic field stimulus. Literature provides information that solutal advection and solutal Marangoni effect lead to enhancement of evaporation in droplets with ionic inclusions. The major crux of the present article remains to modulate the thermosolutal advection with the aid of magnetic field and comprehend the dynamics of the evaporation process under such complex multiphysics interactions. Experimental observations reveal that the evaporation rate enhances as a direct function of the magnetic moment of the solvated magnetic element ions, thereby pinpointing at the magnetophoretic and magneto-solutal advection. Additionally, flow visualization by PIV illustrates that the internal advection currents within the droplet are strengthened in magnitude as well as distorted in orientation by the magnetic field. A mathematical formalism based on magnetothermal and magnetosolutal advection effects has been proposed via scaling analysis of the species and energy conservation equations. The formalism takes into account all major governing factors such as the magnetothermal and magnetosolutal Marangoni numbers, magneto Prandtl and magneto Schmidt numbers and the Hartmann number. The modeling establishes the magnetosolutal advection component to be the domineering factor in augmented evaporation dynamics. Accurate validation of the experimental internal circulation velocity is obtained from the proposed model. The present study reveals rich insight on the magneto thermosolutal hydrodynamics aspects in paramagnetic droplets.
A New Method for Calculating Counts in Cells
Creators: name: Szapudi, Istvan
Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In the near future a new generation of CCD based galaxy surveys will enable high precision determination of the N-point correlation functions. The resulting information will help to resolve the ambiguities associated with two-point correlation functions thus constraining theories of structure formation, biasing, and Gaussianity of initial conditions independently of the value of $Ω$. As one the most successful methods to extract the amplitude of higher order correlations is based on measuring the distribution of counts in cells, this work presents an advanced way of measuring it with unprecedented accuracy. Szapudi and Colombi (1996, hereafter \cite{sc96}) identified the main sources of theoretical errors in extracting counts in cells from galaxy catalogs. One of these sources, termed as measurement error, stems from the fact that conventional methods use a finite number of sampling cells to estimate counts in cells. This effect can be circumvented by using an infinite number of cells. This paper presents an algorithm, which, in practice achieves this goal, i.e. it is equivalent to throwing an infinite number of sampling cells in finite time. The errors associated with sampling cells are completely eliminated by this procedure which will be essential for the accurate analysis of future surveys.

description: We compute isospin-violating meson-nucleon coupling constants and their consequent charge-symmetry-breaking nucleon-nucleon potentials. The couplings result from evaluating matrix elements of quark currents between nucleon states in a nonrelativistic constituent quark model; the isospin violations arise from the difference in the up and down constituent quark masses. We find, in particular, that isospin violation in the omega-meson--nucleon vertex dominates the class IV CSB potential obtained from these considerations. We evaluate the resulting spin-singlet--triplet mixing angles, the quantities germane to the difference of neutron and proton analyzing powers measured in elastic $\vec{n}-\vec{p}$ scattering, and find them commensurate to those computed originally using the on-shell value of the $ρ$-$ω$ mixing amplitude. The use of the on-shell $ρ$-$ω$ mixing amplitude at $q^2=0$ has been called into question; rather, the amplitude is zero in a wide class of models. Our model possesses no contribution from $ρ$-$ω$ mixing at $q^2=0$, and we find that omega-meson exchange suffices to explain the measured $n-p$ analyzing power difference~at~183 MeV.

Value plurality and multifunctional commensuration in organisation : a systems-theoretical approach

description: This article aims to challenge the prevailing economic bias in studies of organised valuation and commensuration by exploring the broader plurality of values that organisations must manage. The article draws on social systems theory in the tradition of German sociologist Niklas Luhmann to conceptualise organisations as multifunctional systems of decisions that pertain to and commensurate a plurality values associated with a diverse set of value domains, also known as ‘function systems’. The utility of the proposed framework is demonstrated through cases related to carbon rationing and legal issues during the coronavirus crisis. A key finding is that commensuration is not limited to processes dominated by financial metrics, as political and educational metrics, among others, can also serve as primary drivers of commensuration processes, effectively guiding organisational decision-making. The paper demonstrates how organisations can effectively commensurate diverse value systems without relying solely on financial metrics and concludes that future research in non-/financial of valuation and commensuration will be crucial for developing more nuanced and multifaceted strategies and concepts, including multifunctional approaches to the formation, justification, and management of moral judgements and values.

A recent successful example is the demonstration of van der Waals (vdW) heterostructures,1-3 in which atomic layers are stacked on each other and different ingredients can be combined beyond symmetry and lattice matching. This concept, usually described as a nanoscale Lego blocks, allows to build sophisticated structures layer by layer. However, this concept has been so far limited in two dimensional (2D) materials. Here we show a class of new material where different layers are coaxially (instead of planarly) stacked. As the structure is in one dimensional (1D) form, we name it "1D vdW heterostructures". We demonstrate a 5 nm diameter nanotube consisting of three different materials: an inner conductive carbon nanotube (CNT), a middle insulating hexagonal boron nitride nanotube (BNNT) and an outside semiconducting MoS2 nanotube. As the technique is highly applicable to other materials in the current 2D libraries,4-6 we anticipate our strategy to be a starting point for discovering a class of new semiconducting nanotube materials. A plethora of function-designable 1D heterostructures will appear after the combination of CNTs, BNNTs and semiconducting nanotubes.

description: We discuss a number of lattice fermion actions solving the Ginsparg-Wilson relation. We also consider short ranged approximate solutions. In particular, we are interested in reducing the lattice artifacts, while avoiding (or suppressing) additive mass renormalization. In this context, we also arrive at a formulation of improved domain wall fermions.

Looking for Novel CP-Violating Effects in B->K^*l^+l^-

description: The CP-violating asymmetries in the exclusive decay B->K^*l^+l^- (l=e,mu,tau) are predicted to be exceedingly small in the standard model (SM), thereby offering an opportunity to assess various new-physics scenarios. We derive quantitative predictions for various integrated observables in B->K^*mu^+mu^- decay in the presence of physics beyond the SM with additional CP phases and an extended operator basis. In particular, a model-independent analysis of CP asymmetries that require the presence of unitarity phases, in addition to CP violation, is performed. We find that in the low dimuon invariant mass region 2m_mus gamma rate and the upper limit on BR(B^0->K^{*0}mu^+mu^-), CP-violating effects of a few per cent are estimated, even in the presence of new physics with CP phases of O(1). By contrast, in the high dimuon invariant mass region M_{psi'}

description: International organizations (IOs) and their bureaucracies frequently face calls for reform. To express discontent and exert reform pressure, member states can withhold their budgetary contributions to IOs. In extreme cases, these cuts result in organizational crises during which reform efforts become unavoidable, as happened in UNESCO after 2011. Traditional IR research sees member states as being in the driver’s seat when it comes to achieving – or failing to achieve – reform under such conditions, whereas scholars of international public administration underline bureaucratic action or pathology as driving, or preventing, reform. By tracing UNESCO’s reform dynamics from 2011 to 2013, this paper demonstrates how a budget crisis can trigger major reform efforts by IO bureaucracies and by IO member states, but how the lack of joint and synchronized action by both actors still results in failed or limited reform. This contributes to key debates on international public administration, IO reform, and the role of budgetary crisis. The article suggests a dynamic and actor-centred theory of IO reform that highlights the need for synchronized crisis cognition and for substantively and temporally coordinated efforts of both states and bureaucracies as key elements for reform success – and their absence as explanation for failed reform.
Absorption of dilaton s-wave in type 0B string theory

Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We find the absorption probability of dilaton field in type 0B string theory. Since the background solutions are of the form $AdS_5 \times S^5$ on both regions, we use the semiclassical formalism adopted in type IIB theory to find the absorption cross section. The background tachyon field solution was used as a reference to relate the solutions of the two regions. We also consider the possible corrections to absorption probability and the $\ln(\ln z)$ form of the correction is expected as in the calculation of the confinement solution.

description: With the discovery of charge density waves (CDW) in most members of the cuprate high temperature superconductors, the interplay between superconductivity and CDW has become a key point in the debate on the origin of high temperature superconductivity. Some experiments in cuprates point toward a CDW state competing with superconductivity, but others raise the possibility of a CDW-superconductivity intertwined order, or more elusive pair-density wave (PDW). Here we have used proton irradiation to induce disorder in crystals of La$_{1.875}$Ba$_{0.125}$CuO$_4$ and observed a striking 50% increase of $T_\mathrm{c}$ accompanied by a suppression of the CDW. This is in clear contradiction with the behaviour expected of a d-wave superconductor for which both magnetic and non-magnetic defects should suppress $T_\mathrm{c}$. Our results thus make an unambiguous case for the strong detrimental effect of the CDW on bulk superconductivity in La$_{1.875}$Ba$_{0.125}$CuO$_4$. Using tunnel diode oscillator (TDO) measurements, we find evidence for dynamic layer decoupling in PDW phase. Our results establish irradiation-induced disorder as a particularly relevant tuning parameter for the many families of superconductors with coexisting density waves, which we demonstrate on superconductors such as the dichalcogenides and Lu$_5$Ir$_4$Si$_{10}$.

description: Bei der empirischen Untersuchung der Praxis der Geschäftsprozessmodellierung ist man auf eine umfangreiche, vielfältige und gleichzeitig zur Aufgabenstellung passende Datenbasis angewiesen. Wir untersuchen eine Reihe öffentlich zugänglicher Modellrepositorys mit BPMN-Modellen, die in den vergangenen Jahren entstanden sind. Wir weisen auf Eigenarten der Repositorys hin, die die Verarbeitung der Daten erschweren und die Datenqualität beeinträchtigen. Besonders diskutiert wird das in bisherigen Arbeiten nicht betrachtete Phänomen von de facto inhaltsgleichen Modellen in bei bitweisem Vergleich verschiedenen Dateien. Wir diskutieren die Auswirkung solcher Duplikate und schlagen eine der jeweiligen Aufgabenstellung angepasste Filterung vor. Wir begründen, warum dieses Vorgehen insbesondere bei Ansätzen zum maschinellen Lernen beachtet werden sollte. Wir stellen fest, dass die empfohlenen Maßnahmen zur Sicherung der Datenqualität in aktuellen Veröffentlichungen häufig noch nicht beachtet werden, was die Aussagekraft von deren Ergebnissen in Frage stellen kann.

description: $g_{K N Λ}$ and $g_{K N Σ}$ are calculated using a QCD sum rule motivated method used by Reinders, Rubinstein and Yazaki to extract Hadron couplings to goldstone bosons. The SU(3) symmetry breaking effects are taken into account by including the contributions from the strange quark mass and assuming different values for the strange and the up down quark condensates. We find $g_{K N Λ}/\sqrt{4 π} = - 1.96 $ and $g_{K N Σ}/\sqrt{4 π} = 0.33 $

description: The computation of microlensing light curves represents a bottleneck for the modeling of planetary events, making broad searches in the vast parameter space of microlensing extremely time-consuming. The release of the first version of VBBinaryLensing (based on the advanced contour integration method presented in Bozza(2010)) has represented a considerable advance in the field, with the birth of several analysis platforms running on this code. Here we present the version 2.0 of VBBinaryLensing, which contains several upgrades with respect to the first version, including new decision trees that introduce important optimizations in the calculations.

Tadpole-improved SU(2) lattice gauge theory

Year: 1998
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: A comprehensive analysis of tadpole-improved SU(2) lattice gauge theory is made. Simulations are done on isotropic and anisotropic lattices, with and without improvement. Two tadpole renormalization schemes are employed, one using average plaquettes, the other using mean links in Landau gauge. Simulations are done with spatial lattice spacings $a_s$ in the range of about 0.1--0.4 fm. Results are presented for the static quark potential, the renormalized lattice anisotropy $a_t/a_s$ (where $a_t$ is the ``temporal'' lattice spacing), and for the scalar and tensor glueball masses. Tadpole improvement significantly reduces discretization errors in the static quark potential and in the scalar glueball mass, and results in very little renormalization of the bare anisotropy that is input to the action. We also find that tadpole improvement using mean links in Landau gauge results in smaller discretization errors in the scalar glueball mass (as well as in the static quark potential), compared to when average plaquettes are used. The possibility is also raised that further improvement in the scalar glueball mass may result when the coefficients of the operators which correct for discretization errors in the action are computed beyond tree level.

description: The type II supernova is considered as a candidate site for the production of heavy elements. Since the supernova produces an intense neutrino flux, neutrino scattering processes will impact element formation. We examine active-sterile neutrino conversion in this environment and find that it may help to produce the requisite neutron-to-seed ratio for synthesis of the r-process elements.
