description: We discuss how life-time broadening of quasiparticle states influences single- and two-particle current transport through zero-energy states at normal metal/d-wave superconductor junctions. We distinguish between intrinsic broadening (imaginary part $η$ of the energy), which couples the bound states with the superconducting reservoir, and broadening due to leakage through the junction barrier, which couples the bound states with the normal metal reservoir. We show that shot noise is highly sensitive to the mechanism of broadening, while the conductance is not. In the limit of small but finite intrinsic broadening, compared to the junction transparency $D$, $η/Δ_0\ll D$, the low-voltage shot noise at zero frequency and zero temperature becomes proportional to the magnitude $η$ of intrinsic broadening ($Δ_0$ is the maximum d-wave gap).

description: Extensive air showers are complex objects, resulting of billions of particle reactions initiated by single cosmic ray at ultra-high-energy. Their characteristics are sensitive both to the mass of the primary cosmic ray and to the details of hadronic interactions. Many of the interactions that determine the shower features occur in kinematic regions and at energies beyond those tested by human-made accelerators. We will report on the measurement of the proton-air cross section for particle production at a center-of-mass energy per nucleon of 39 TeV and 56 TeV. We will also show comparisons of post-LHC hadronic interaction models with shower data by studying the moments of the distribution of the depth of the electromagnetic maximum, the number and production depth of muons in air showers, and finally a parameter based on the rise-time of the surface detector signal, sensitive to the electromagnetic and muonic component of the shower. While there is good agreement found for observables based on the electromagnetic shower component, discrepancies are observed for muon-sensitive quantities.

description: In this paper we derive a joint continuous/censored demand system suitable for the analysis of commodity demand relationships using panel data. Unobserved heterogeneity is controlled for using a correlated random effects specification and a Generalized Method of Moments framework used to estimate the model in two stages. In the first stage reduced form parameters are obtained through either ordinary least squares or heteroscedastic Tobit estimation, followed by the identification of structural parameters and imposition of cross-equation restrictions using minimum distance techniques. The procedure, which is demonstrated on data from Romania, yields elasticity estimates that lie within an intuitively pleasing range and reveals strong cross-substitution patterns between many commodity groups.

description: Signatures of quantum transport are expected to quickly vanish as dissipation is introduced in a system. This dissipation can take several forms, including that of particle loss, which has the consequence that the total probability current is not conserved. Here, we study the effect of such losses at a quantum point contact (QPC) for ultracold atoms. Experimentally, dissipation is provided by a near-resonant optical tweezer whose power and detuning control the loss rates for the different internal atomic states as well as their effective Zeeman shifts. We theoretically model this situation by including losses in the Landauer-Büttiker formalism over a wide range of dissipative rates. We find good agreement between our measurements and our model, both featuring robust conductance plateaus. Finally, we are able to map out the atomic density by varying the position of the near-resonant tweezer inside the QPC, realizing a dissipative scanning gate microscope for cold atoms.

description: Molecular dynamics (MD) simulation has been employed to study the nonequilibrium structure formation of two types of particles in a colloidal suspension, driven by type-dependent forces. We examined the time evolution of structure formation as well as the structural properties of the resulting aggregation by studying the radial distribution function (RDF). The resulting aggregation is well described by a binary colloidal gelation. We compared the structural properties to those for one type of particles. From the MD results, it is evident that there are significant differences between the RDF's of the two cases. Moreover, we found that the average coordination number is generally larger in the monodisperse case for all area fractions considered. Thus, by means of heterogeneous aggregation, it is possible to obtain a wide variety of structures while more close-packed structures are formed for monodisperse colloidal aggregation.

description: We review the notion of complementarity of observables in quantum mechanics, as formulated and studied by Paul Busch and his colleagues over the years. In addition, we provide further clarification on the operational meaning of the concept, and present several characterisations of complementarity - some of which new - in a unified manner, as a consequence of a basic factorisation lemma for quantum effects. We work out several applications, including the canonical cases of position-momentum, position-energy, number-phase, as well as periodic observables relevant to spatial interferometry. We close the paper with some considerations of complementarity in a noisy setting, focusing especially on the case of convolutions of position and momentum, which was a recurring topic in Paul's work on operational formulation of quantum measurements and central to his philosophy of unsharp reality.
Hagedorn transition for strings on pp-waves and tori with chemical potentials

description: It has been conjectured that string theory in a pp-wave background is dual to a sector of N=4 supersymmetric Yang-Mills theory. We study the Hagedorn transition for free strings in this background. We find that the free energy at the transition point is finite suggesting a confinement/deconfinement transition in the gauge theory. In the limit of vanishing mass parameter the free energy matches that of free strings on an 8-torus with momentum/winding chemical potential. The entropy in the microcanonical ensemble with fixed energy and fixed momentum/winding is computed in each case.

Pebble-driven planet formation for TRAPPIST-1 and other compact systems

description: Recently, seven Earth-sized planets were discovered around the M-dwarf star TRAPPIST-1. Thanks to transit-timing variations, the masses and therefore the bulk densities of the planets have been constrained, suggesting that all TRAPPIST-1 planets are consistent with water mass fractions on the order of 10%. These water fractions, as well as the similar planet masses within the system, constitute strong constraints on the origins of the TRAPPIST-1 system. In a previous work, we outlined a pebble-driven formation scenario. In this paper we investigate this formation scenario in more detail. We used a Lagrangian smooth-particle method to model the growth and drift of pebbles and the conversion of pebbles to planetesimals through the streaming instability. We used the N-body code \texttt{MERCURY} to follow the composition of planetesimals as they grow into protoplanets by merging and accreting pebbles. This code is adapted to account for pebble accretion, type-I migration, and gas drag. In this way, we modelled the entire planet formation process (pertaining to planet masses and compositions, not dynamical configuration). We find that planetesimals form in a single, early phase of streaming instability. The initially narrow annulus of planetesimals outside the snowline quickly broadens due to scattering. Our simulation results confirm that this formation pathway indeed leads to similarly-sized planets and is highly efficient in turning pebbles into planets ($\sim$50% solids-to-planets conversion efficiency). [...] The water content of planets resulting from our simulations is on the order of 10%, and our results predict a `V-shaped' trend in the planet water fraction with orbital distance: from relatively high (innermost planets) to relatively low (intermediate planets) to relatively high (outermost planets).

description: This research presents an integrated model of service quality, price fairness, and ethical practice for customer satisfaction in Indonesia’s first sharing economy platform while also assessing customers perceived value as a mediating variable. Utilizing partial-least-squares (PLS), an analysis was conducted based on the 219 surveys collected to test for the proposed relationships. It is revealed that service quality, price fairness, and ethical practice of this sharing economy platform significantly impacts on customer satisfaction through the essential roles of perceived value. The results exhibited that service quality has a direct and indirect influence on customers’ satisfaction in which perceived value is partially mediated between service quality and customer satisfaction. Nevertheless, price fairness and ethical practice both influence customer satisfaction indirectly through customer perceived value in which its role is a complete mediation to customer satisfaction. The findings also suggest that corporates can integrate and include service quality, price fairness, and ethical practice in their strategic plan to improve customers’ satisfaction. Additionally, the strategic consequence of these findings is also to improve corporates’ competitive advantage in a high level of competition in this mode of business.

description: The spontaneous production of electron-positron pairs from the vacuum--in a field configuration composed of a high-frequency electric mode of weak intensity and a strong constant electric field--is investigated. Asymptotic expressions for the single-particle distribution function ruling this nonperturbative process are established by considering the low-density approximation in the Boltzmann-Vlasov equation. An analytical formula for the density rate of yielded particles is established which is shown to manifest a nonperturbative dependence on both the strong and weak electric fields and to interpolate between the tunneling and multi-photon regimes. It is shown that--under appropriate circumstances--the produced plasma of electrons and positrons might reach densities for which their recombinations into high-energy photons occurs copiously. On the basis of this feature, an experimental setup for observing the dynamically-assisted Schwinger effect is put forward.

description: A detailed study of the muonic analogue of neutrinoless double beta decay, (muon^-,muon^+) conversion, has been carried out for the A=44 nuclear system. We studied several lepton number violating (LNV) mechanisms potentially triggering this process: exchange by light and heavy Majorana neutrinos as well as exchange by supersymmetric particles participating in R-parity violating interactions. The nuclear structure has been taken into account within the renormalized Quasiparticle Random Phase Approximation method. To our knowledge, this is the first realistic treatment of nuclear structure aspects of the (muon^-,muon^+) conversion. We estimated the rate of this process utilizing the existing experimental constraints on the parameters of the underlying LNV interactions and conclude that the (muon^-,muon^+) conversion is hardly detectable in the near future experiments.

In that sense, the key innovation factors important for this domain have been identified, based on selected research in the broader area of innovation management. Survey results give one of the rare insights in innovativeness level and characteristics in this important part of the nonprofit sector of a transition economy. In this specific case, that should be the prior investigation with the intention of helping managers to improve organization propensity to innovate and to define/reexamine innovation strategy. Research findings revealed that innovation factors measurement should be considered very important for ICT innovation management in the library system, and that further research would be necessary.

description: A model of fluctuations in the market price including many deterministic dealers, who predict their buying and selling prices from the latest price change, is developed. We show that price changes of the model is approximated by ARCH(1) process. We conclude that predictions of dealers affected by the past price changes cause the fat tails of probability density function. We believe that this study bridges stochastic processes in econometrics with multi-agent simulation approaches.

Abstract: For years, eye tracking technology has been making huge improvements and has become very popular in the robotics industry. This paper covers a new concept resulting in the creation of a fully functioning prototype utilising eye tracking technology that can aid with such things as improved visibility or better communication for people in the workplace or at home. The concept involves a portable headset that can track the user’s gaze direction and accurately point an illumination source at the point of eye fixation. Use cases for such a device could include assisting people working in low light conditions by directing a beam of light in the gaze direction or for people living with disabilities that possess substandard verbal communication skills, by acting as an eye-controlled laser pointer. The prototype uses digital servo motors, a 3D printed pan-tilt platform, a microcontroller, an illumination source and off-the-shelf eye-tracking glasses. The result is a responsive and accurate device that could potentially be transformative for many people around the globe.

description: The functionality of classically-instructed remotely prepared random secret qubits was introduced in (Cojocaru et al 2018) as a way to enable classical parties to participate in secure quantum computation and communications protocols. The idea is that a classical party (client) instructs a quantum party (server) to generate a qubit to the server's side that is random, unknown to the server but known to the client. Such task is only possible under computational assumptions. In this contribution we define a simpler (basic) primitive consisting of only BB84 states, and give a protocol that realizes this primitive and that is secure against the strongest possible adversary (an arbitrarily deviating malicious server). The specific functions used, were constructed based on known trapdoor one-way functions, resulting to the security of our basic primitive being reduced to the hardness of the Learning With Errors problem. We then give a number of extensions, building on this basic module: extension to larger set of states (that includes non-Clifford states); proper consideration of the abort case; and verifiablity on the module level. The latter is based on "blind self-testing", a notion we introduced, proved in a limited setting and conjectured its validity for the most general case.

description: In radiopharmaceutical therapy (RPT), cocktails of radionuclides have the potential to target a larger range of metastatic lesion sizes compared to single radionuclides. Given the number of radionuclides becoming clinically available, there has been a renewed interest in the investigation of the use of radionuclide cocktails for RPT.The aim of this study was to provide a radiobiological framework to investigate the therapeutic efficacy of radionuclide cocktails. Dose response in terms of biological effective dose (BED), tumour control probability (TCP) and normal-tissue complication was modelled for cocktails of radionuclides of recent interest in the field of RPT (67Cu, 166Ho, 188Re and 225Ac), in addition to the more conventional cocktail radionuclides 90Y and 177Lu.Uniform distribution of radionuclide cocktails have been simulated in the Geant4 Monte Carlo toolkit with variable initial activity concentration ratios. The BED was modified to include the absorbed dose-rate effects from the simultaneous administration of 2 radionuclides and TCP values in solid tumours ranging from 100 μm to 2.5 cm were estimated. The equivalent uniform equieffective dose (EUEQDX) to surrounding tissue was assessed up to a distance 3 times the lesion radius for evaluation of normal-tissue complication.The theoretical benefits of cocktails for treatment of metastatic disease are demonstrated with a greater range of tumour sizes experiencing a higher TCP when exposed to a combination of radionuclides rather than either radionuclide alone. When selecting appropriate radionuclide combinations, the half-life and range of emissions must be considered carefully, with most optimal results seen in this study after combining 177Lu with 166Ho or 225Ac. Care must also be taken with the ratio of administered radionuclide activity concentrations, as the TCP is shown to vary significantly in response to these ratios. In any combination considered in this study the surrounding normal-tissue EUEQD2 equivalent to a 2 Gy external beam radiotherapy (EBRT) regime did not exceed 5.3 Gy.This modelling study provides a framework for the assessment of dose response and normal-tissue toxicity in the use of novel radionuclide cocktails in RPT. The approach proposed in this work can be used, in the future, to tailor the treatment of metastatic lesions for individual patients by supporting the selection of cocktail of radionuclides of given composition, when appropriate, over single radionuclides.

description: The hole-doped manganite La0.7Ca0.3MnO3 and the electron-doped manganite La0.7Ce0.3MnO3 undergo an insulator to metal transition at around 250 K, above which both behave as a polaronic semiconductor. We have successfully fabricated an epitaxial trilayer (La0.7Ca0.3MnO3/SrTiO3/La0.7Ce0.3MnO3), where SrTiO3 is an insulator. At room temperature, i.e. in the semiconducting regime, it exhibits asymmetric current-voltage (I-V) characteristics akin to a p-n diode. The observed asymmetry in the I-V characteristics disappears at low temperatures where both the manganite layers are metallic. To the best of our knowledge, this is the first report of such a p-n diode, using the polaronic semiconducting regime of doped manganites.

description: This study attempts to find out the significance of demographic factors of population such as gender, age, education, occupation, income, savings and family size over several elements of investment decisions like priorities based on characteristics of investments, period of investment, reach of information source, frequency of investment and analytical abilities. The study was made by conducting a survey in Nagapattinam district of Tamilnadu, South India and the statistical inferences were deduced using computer software tools. The study reveals that the demographic factors have a significant influence over some of the investment decision elements and insignificant in others elements too. The study also discloses a general view of investors perception over various investment avenues.

description: MAXI J1820+070, a black hole candidate first detected in early March 2018, was observed by XMM-Newton during the outburst rise. In this letter we report on the spectral and timing analysis of the XMM-Newton X-ray and UV data, as well as contemporaneous X-ray data from the Swift satellite. The X-ray spectrum is well described by a hard thermal Comptonization continuum. The XMM-Newton X-ray light curve shows a pronounced dipping interval, and spectral analysis indicates that it is caused by a moderately ionized partial covering absorber. The XMM-Newton/OM U-filter data does not reveal any signs of the 17 hr orbital modulation that was seen later on during the outburst decay. The UV/X-ray cross correlation function shows a complex shape, with a peak at positive lags of about 4 seconds and a pre-cognition dip at negative lags, which is absent during the X-ray dipping episode. Such shape could arise if the UV emission comes partially from synchrotron self-Compton emission near the black hole, as well as from reprocessing of the X-rays in the colder accretion disc further out.

description: Excerpts from the report: The price paid by consumers for milk includes the cost of a wide variety of marketing services in addition to the amount which the farmer receives. Traditionally, the farmer's share and the amount spent for marketing services have been measured by a simple calculation: The farm price per quart was subtracted from the retail price per quart, and the difference equaled the charge for marketing services. One purpose of this study was to learn how the results of a simple calculation of the price spread for milk would compare with a broader measure of the marketing margin on milk in the Chicago market. Another purpose was to describe the agencies involved and the services performed in moving milk from the farm to the consumer, and to measure some of the charges made for such services. The marketing margin for milk goes to a number of kinds of businesses that take part in getting milk from the farm to the consumer's doorstep. Country milk haulers, country milk plants, long-distance haulers, city bottling plants, vendors or subdealers, and retail stores of various kinds all provide needed services. About 59 percent of the consumer's dollar for fresh milk went for such services in Chicago in May 1956.

description: This article looks at the transition from the model of relationship between business and state, which dominated in Russia in the 1990s, to the one at the beginning of the 21st century. Russian history provides extensive evidence that business and state had always been closely connected and interdependent in this country. However, after the collapse of the Soviet Union, interdependency changed to dependency: while in the 1990s business was dominating the state, on the edge of two centuries the state took control over business. The tradition of close co-operation has been destroyed.

Kawasaki-type Dynamics: Diffusion in the kinetic Gaussian model

description: In this article, we retain the basic idea and at the same time generalize Kawasaki's dynamics, spin-pair exchange mechanism, to spin-pair redistribution mechanism, and present a normalized redistribution probability. This serves to unite various order-parameter-conserved processes in microscopic, place them under the control of a universal mechanism and provide the basis for further treatment. As an example of the applications, we treated the kinetic Gaussian model and obtained exact diffusion equation. We observed critical slowing down near the critical point and found that, the critical dynamic exponent z=1/nu=2 is independent of space dimensionality and the assumed mechanism, whether Glauber-type or Kawasaki-type.

description: Optical and radio observations of shock-ionised bubble nebulae surrounding ultraluminous X-ray sources (ULXs) suggest that they are powered by jets or super-critical outflows presumably launched from the ULX accretion disc. Recent simulations of these systems have shown that the shocked wind can emit thermal X-rays with estimated luminosities $\sim 10^{36}$ erg s$^{-1}$. In this work, we investigated whether it is possible to detect and spatially resolve the X-ray emission from these systems using archival Chandra observations of the ULX Holmberg IX X-1. This source is an ideal target to study for two reasons: it is surrounded by an optical bubble nebula with a large spatial extent ($\sim$ 400 pc) that can easily be resolved with Chandra. Further, it has a hard X-ray continuum that is easily distinguishable from the expected soft thermal emission from the nebula. However, a spectral and photometric analysis on stacked Chandra observations of the source reveals that there is no strong evidence for an X-ray bubble associated with it, to a limiting luminosity of $\sim 2 \times 10^{36}$ erg s$^{-1}$. The detection of such X-ray nebulae may be possible with future X-ray missions such as Athena, which would provide useful constraints on the kinematics of the outflow. Finally, our observations also emphasise that the nebular emission does not contribute significantly to the residuals in the X-ray spectrum of the source, which are more likely to be linked to processes localised to the ULX.
