Bertrand versus Cournot with Convex Variable Costs
Creators: name: Delbono, Flavio
name: Lambertini, Luca
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2015
Subjects: SECS-P/02 Politica economica

description: Within a simple model of homogeneous oligopoly, we show that the traditional ranking between Bertrand and Cournot equilibria may be reversed. For price setting entails a continuum of price equilibria under convex variable costs, departure from marginal cost pricing may be observed. As a consequence, Bertrand-Nash equilibrium profits (welfare) may be higher (lower) than Cournot-Nash ones. The reversal of the standard rankings occurs when pricing strategies mimic collusive behaviour.
Pfaffian statistics through adiabatic transport in the 1D coherent state representation

description: Recent work has shown that the low energy sector of certain quantum Hall states is adiabatically connected to simple charge-density-wave patterns that appear, e.g., when the system is deformed into a thin torus. Here it is shown that the patterns emerging in this limit already determine the non-abelian statistics of the $ν=1$ Moore-Read state. Aside from the knowledge of these patterns, the method only relies on the principle of adiabatic continuity, the effectively noncommutative geometry in a strong magnetic field, and topological as well as locality arguments.

Turnaround radius in $Λ$CDM, and dark matter cosmologies II: the role of dynamical friction

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: This paper is an extension of the paper by Del Popolo, Chan, and Mota (2020) to take account the effect of dynamical friction. We show how dynamical friction changes the threshold of collapse, $δ_c$, and the turn-around radius, $R_t$. We find numerically the relationship between the turnaround radius, $R_{\rm t}$, and mass, $M_{\rm t}$, in $Λ$CDM, in dark energy scenarios, and in a $f(R)$ modified gravity model. Dynamical friction gives rise to a $R_{\rm t}-M_{\rm t}$ relation differing from that of the standard spherical collapse. In particular, dynamical friction amplifies the effect of shear, and vorticity already studied in Del Popolo, Chan, and Mota (2020). A comparison of the $R_{\rm t}-M_{\rm t}$ relationship for the $Λ$CDM, and those for the dark energy, and modified gravity models shows, that the $R_{\rm t}-M_{\rm t}$ relationship of the $Λ$CDM is similar to that of the dark energy models, and small differences are seen when comparing with the $f(R)$ models. The effect of shear, rotation, and dynamical friction is particularly evident at galactic scales, giving rise to a difference between the $R_{\rm t}-M_{\rm t}$ relation of the standard spherical collapse of the order of $\simeq 60\%$. Finally, we show how the new values of the $R_{\rm t}-M_{\rm t}$ influence the constraints to the $w$ parameter of the equation of state.

description: Cities have huge potential for PV applications, namely in the façades of buildings that feature high available surface area. Since PV modules convert part of the incoming solar radiation into electricity, lower amounts of heat are expected to be released from the buildings into the street. A cooling effect might be expected as PV deployment increases, yet this is still an overlooked approach to mitigate urban heat island effects. In this study we evaluated the impact of high penetration of PV systems (façade and rooftop) in the urban microclimate of a neighbourhood in Lisbon, using ENVI-met software. Hourly temperatures in the surfaces of several buildings and in strategic outdoor places were estimated for a typical summer day, comparing between the scenarios: 1) without any PV deployment; 2) with PV only in façades; and 3) with PV in both façades and rooftops. The results show that PV only in facades promotes a slight cooling effect in the late afternoon/evening, for the outdoor air at 2 meters height, whereas a full PV deployment transfers this effect into daytime. It is apparent that PV will be almost innocuous for the radiative balance in the urban environment, although the more PV installed the lower the average air temperatures might be in urban canyons. Nevertheless, several improvements to the simulation methods are needed before drawing more general conclusions, thus the development of proper PV panel components to this type of modelling software is recommended.

description: The electron tunneling through a molecular junction modeled by a single site weakly coupled to two leads is studied in the presence of a time-dependent external field using a master equation approach. In the case of small bias voltages and high carrier frequencies of the external field, we observe the phenomenon of coherent destruction of tunneling, i.e. the current through the molecular junction vanishes completely for certain parameters of the external field. In previous studies the tunneling within isolated and open multi-site systems was suppressed; it is shown here that the tunneling between a single site and electronic reservoirs, i.e. the leads, can be suppressed as well. For larger bias voltages the current does not vanish any more since further tunneling channels participate in the electron conduction and we also observe photon-assisted tunneling which leads to steps in the current-voltage characteristics. The described phenomena are demonstrated not only for monochromatic fields but also for laser pulses and therefore could be used for ultrafast optical switching of the current through molecular junctions.

PV Module Design, Manufacture, Performance and Reliability

description: Most commercial crystalline silicon modules are encapsulated with ethylene-vinyl acetate (EVA) and polymer backsheets to provide protection against environmental exposure. EVA is a moisture sensitive material in which a hydrolysis reaction will occur to produce acetic acid in the presence of heat and moisture. However, polyester backsheets cannot completely block the moisture ingress into the module. So, the hydrolysis reaction of EVA is inevitable. But different polyester backsheets have different water vapor transmission rate (WVTR). At present, there is no definite conclusion about the WVTR selection of backsheets in tropics area. The most common practice in the PV industry is to assess the backsheet's suitability for the tropics through extended damp heat testing. In this work, first we investigate the degradation of modules with different backsheets through extended 3000hrs damp heat test, and correlate this to the backsheet WVTR. The results showed that the double glass modules and the modules without backshseet have lowest power degradation. For double glass module, almost no moisture can ingress into the modules and also no hydrolysis reaction occurred. For the modules without backsheet, although the hydrolysis reaction occurred, the acetic acid also can release totally. For the modules encapsulated with backsheet WVTR of 0.6g/m2.day, 1.25 g/m2d·ay, 2.34 g/m2d·ay, 3.30 g/m2d·ay, the power degradation increased with the WVTR. Then, we also analyze the failure mechanism of the modules installed in the tropic area and the modules after received extended damp heat test using FTIR. We found that these modules have similar failure mechanism. Lead acetate can be detected on the EVA. So the modules’ failure activation energy in the tropic area can be obtained. Then we can use Hallberg-Peck model to calculate the different indoor extended damp heat testing time at different temperature and relative humidity area.

description: The goal of this work was to develop a sustainability study in five campuses of the Universitat Politècnica de Catalunya (UPC) around Catalunya, i.e. Campus Nord and Campus Sud in Barcelona city, Campus Baix Llobregat, Campus Manresa and Campus Vilanova i la Geltrú. The amount of consumed energy was calculated to consider reducing, if possible, the contracted power capacity. Additionally, it was proposed to self-consume part of the produced energy using photovoltaic (PV) systems of 25, 50 and 100 kWp and c-Si, Poly or CdTe Technology in order to reduce the environmental impact. Finally, an economic analysis of all the proposed facilities was conducted to examine their financial feasibility.

description: We apply the ADM 3+1 formalism to derive the general relativistic magnetohydrodynamic equations for cold plasma in spatially flat Schwarzschild metric. Respective perturbed equations are linearized for non-magnetized and magnetized plasmas both in non-rotating and rotating backgrounds. These are then Fourier analyzed and the corresponding dispersion relations are obtained. These relations are discussed for the existence of waves with positive angular frequency in the region near the horizon. Our results support the fact that no information can be extracted from the Schwarzschild black hole. It is concluded that negative phase velocity propagates in the rotating background whether the black hole is rotating or non-rotating.

description: Stellar flares are an important aspect of magnetic activity -- both for stellar evolution and circumstellar habitability viewpoints - but automatically and accurately finding them is still a challenge to researchers in the Big Data era of astronomy. We present an experiment to detect flares in space-borne photometric data using deep neural networks. Using a set of artificial data and real photometric data we trained a set of neural networks, and found that the best performing architectures were the recurrent neural networks (RNNs) using Long Short-Term Memory (LSTM) layers. The best trained network detected flares over {$5σ$ with $\gtrsim80$\% recall and precision} and was also capable to distinguish typical false signals (e.g. maxima of RR Lyr stars) from real flares. Testing the network trained on Kepler data on TESS light curves showed that the neural net is able to generalize and find flares - with similar effectiveness - in completely new data having previously unseen sampling and characteristics.

description: We demonstrate novel instrumentation for spontaneous Raman spectroscopy in biofluids, enabling development of a portable, automated, reliable diagnostics technique requiring minimal operator expertise to quantify disease markers. Label-free Raman analysis of biofluids at physiologically-relevant sensitivities is achieved using a microfluidic-embedded liquid-core-waveguide augmented with a unique circulation approach: thermal damage and spectrum variance is minimized, eliminating conventional limits on integration time for excellent signal-to-noise ratio and temporal stability. Machine-learning then optimizes spectrum processing, yielding quantitative results independent of end-user proficiency. Sub-mM accuracy is achieved in solutions of both high and low turbidity, surpassing the sensitivity of previous techniques for analytes with a small scattering cross-section, such as glucose. We attain a new record for label-free glucose measurements in an artificial whole-blood, achieving an accuracy up to 0.14 mM, well-exceeding the 0.78 mM accuracy required for diabetic monitoring, establishing our technique's potential to significantly facilitate portable Raman for complex biofluid analysis.

description: Galactic winds are a prime suspect for the metal enrichment of the intergalactic medium and may have a strong influence on the chemical evolution of galaxies and the nature of QSO absorption line systems. We use a sample of 1406 galaxy spectra at z~1.4 from the DEEP2 redshift survey to show that blueshifted Mg II 2796, 2803 A absorption is ubiquitous in starforming galaxies at this epoch. This is the first detection of frequent outflowing galactic winds at z~1. The presence and depth of absorption are independent of AGN spectral signatures or galaxy morphology; major mergers are not a prerequisite for driving a galactic wind from massive galaxies. Outflows are found in coadded spectra of galaxies spanning a range of 30x in stellar mass and 10x in star formation rate (SFR), calibrated from K-band and from MIPS IR fluxes. The outflows have column densities of order N_H ~ 10^20 cm^-2 and characteristic velocities of ~ 300-500 km/sec, with absorption seen out to 1000 km/sec in the most massive, highest SFR galaxies. The velocities suggest that the outflowing gas can escape into the IGM and that massive galaxies can produce cosmologically and chemically significant outflows. Both the Mg II equivalent width and the outflow velocity are larger for galaxies of higher stellar mass and SFR, with V_wind ~ SFR^0.3, similar to the scaling in low redshift IR-luminous galaxies. The high frequency of outflows in the star-forming galaxy population at z~1 indicates that galactic winds occur in the progenitors of massive spirals as well as those of ellipticals. The increase of outflow velocity with mass and SFR constrains theoretical models of galaxy evolution that include feedback from galactic winds, and may favor momentum-driven models for the wind physics.

description: This paper focuses on obtaining clustering information about a distribution from its i.i.d. samples. We develop theoretical results to understand and use clustering information contained in the eigenvectors of data adjacency matrices based on a radial kernel function with a sufficiently fast tail decay. In particular, we provide population analyses to gain insights into which eigenvectors should be used and when the clustering information for the distribution can be recovered from the sample. We learn that a fixed number of top eigenvectors might at the same time contain redundant clustering information and miss relevant clustering information. We use this insight to design the data spectroscopic clustering (DaSpec) algorithm that utilizes properly selected eigenvectors to determine the number of clusters automatically and to group the data accordingly. Our findings extend the intuitions underlying existing spectral techniques such as spectral clustering and Kernel Principal Components Analysis, and provide new understanding into their usability and modes of failure. Simulation studies and experiments on real-world data are conducted to show the potential of our algorithm. In particular, DaSpec is found to handle unbalanced groups and recover clusters of different shapes better than the competing methods.

description: In Europe, both the solar irradiation and the support schemes for a household with a PV or a PV battery system differ considerably from country to country. This paper analyses the influence of these factors on economical Key Performance Indicators (KPI) and aims to cluster European countries with similar economic behaviour. The paper focuses on the producer and consumer (=prosumer) concept of residential PV owners. The analysis shows that PV systems are only a positive business case, i.e. a positive NPV calculated based on all economic and technical inputs of each location, in some countries, while in other countries a negative NPV is obtained due to the framework conditions. The PV system in Malta reached the highest NPV due to a high feed-in-tariff. Lowest NPVs were reached for Iceland, Finland, Sweden and UK with no support scheme or only a small feed-in tariff, while also having a lower PV irradiation.
Crossing Symmetry in the Planar Limit

description: Crossing symmetry asserts that particles are indistinguishable from anti-particles traveling back in time. In quantum field theory, this statement translates to the long-standing conjecture that probabilities for observing the two scenarios in a scattering experiment are described by one and the same function. Why could we expect it to be true? In this work we examine this question in a simplified setup and take steps towards illuminating a possible physical interpretation of crossing symmetry. To be more concrete, we consider planar scattering amplitudes involving any number of particles with arbitrary spins and masses to all loop orders in perturbation theory. We show that by deformations of the external momenta one can smoothly interpolate between pairs of crossing channels without encountering singularities or violating mass-shell conditions and momentum conservation. The analytic continuation can be realized using two types of moves. The first one makes use of an $i\varepsilon$ prescription for avoiding singularities near the physical kinematics and allows us to adjust the momenta of the external particles relative to one another within their lightcones. The second, more violent, step involves a rotation of subsets of particle momenta via their complexified lightcones from the future to the past and vice versa. We show that any singularity along such a deformation would have to correspond to two beams of particles scattering off each other. For planar Feynman diagrams, these kinds of singularities are absent because of the particular flow of energies through their propagators. We prescribe a five-step sequence of such moves that combined together proves crossing symmetry for planar scattering amplitudes in perturbation theory, paving a way towards settling this question for more general scattering processes in quantum field theories.

description: The interactive visualization of molecular surfaces can help users to understand the dynamic behavior of proteins in molecular dynamics simulations. These simulations play an important role in biochemical and pharmaceutical research, e.g. in drug design. The efficient calculation of molecular surfaces in a fast and memory-saving way is a challenging task. For example, to gain a detailed understanding of complex diseases like Alzheimer, conformational changes and spatial interactions between molecules have to be investigated. Molecular surfaces, such as Solvent Excluded Surfaces (SES), are instrumental for identifying structures such as tunnels or cavities that critically influence transport processes and docking events, which might induce enzymatic reactions. Therefore, we developed a highly parallelized algorithm that exploits the massive computing power of modern graphics hardware. Our analytical algorithm is suitable for the real-time computation of dynamic SES based on many time steps, as it runs interactively on a single consumer GPU for more than 20 k atoms.

The Warped Plane of the Classical Kuiper Belt

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: By numerically integrating the orbits of the giant planets and of test particles over a period of four billion years, we follow the evolution of the location of the midplane of the Kuiper belt. The Classical Kuiper belt conforms to a warped sheet that precesses with a 1.9 Myr period. The present-day location of the Kuiper belt plane can be computed using linear secular perturbation theory: the local normal to the plane is given by the theory's forced inclination vector, which is specific to every semimajor axis. The Kuiper belt plane does not coincide with the invariable plane, but deviates from it by up to a few degrees in stable zones. For example, at a semimajor axis of 38 AU, the local Kuiper belt plane has an inclination of 1.9 deg and a longitude of ascending node of 149.9 deg when referred to the mean ecliptic and equinox of J2000. At a semimajor axis of 43 AU, the local plane has an inclination of 1.9 deg and a nodal longitude of 78.3 deg. Only at infinite semimajor axis does the Kuiper belt plane merge with the invariable plane, whose inclination is 1.6 deg and nodal longitude is 107.7 deg. A Kuiper belt object keeps its inclination relative to the Kuiper belt plane nearly constant, even while the latter plane departs from the trajectory predicted by linear theory. The constancy of relative inclination reflects the undamped amplitude of free oscillation. Current observations of Classical Kuiper belt objects are consistent with the plane being warped by the giant planets alone, but the sample size will need to increase by a few times before confirmation exceeds 3-sigma in confidence. In principle, differences between the theoretically expected plane and the observed plane could be used to infer as yet unseen masses orbiting the Sun, but carrying out such a program would be challenging.

description: Using our measurements of the H$α$ emission line flux originating in the cool (T $\sim10^4$ K) gas that populates the halos of galaxies, we build a joint model to describe mass of the cool circumgalactic medium (CGM) as a function of galactic stellar mass ($10^{9.5} < ({\rm M_*/M}_\odot) < 10^{11}$) and environment. Because the H$α$ emission correlates with the main cooling channel for this gas, we are able to estimate the rate at which the CGM cools and becomes fuel for star formation in the central galaxy. We describe this calculation, which uses our observations, previous measurements of some critical CGM properties, and modeling of the cooling mechanism using the \cloudy modeling suite. We find that the mass cooling rate is larger than the star formation rates of the central galaxies by a factor of $\sim 4 - 90$, empirically confirming that there is sufficient fuel to resolve the gas consumption problem and that feedback is needed to avoid collecting too much cold gas in galaxies. We find excellent agreement between our estimates of both the mass cooling rates and mass loading factors and the predictions of independent theoretical studies. The convergence in results that we find from several completely different treatments of the problem, particularly at the lower end of the galactic mass range, is a strong indication that we have a relatively robust understanding of the quantitative effects of feedback across this mass range.

In this work, we define an algorithm for a deterministic walk through a two-dimensional grid that we refer to as Prime Walk. The walk is constructed from a sequence of steps dictated by and dependent on the sequence of last digits of the primes. Despite the apparent randomness of this generating sequence, the resulting structure -- both in 2d and 3d -- created by the algorithm presents remarkable properties and regularities in its pattern that we proceed to analyze in detail.

description: Interpretation of machine learning results is a major challenge for non-technical experts, with visualization being a common approach to support this process. For instance, interpretation of clustering results is usually based on scatterplots that provide information about cluster characteristics implicitly through the relative location of objects. However, the locations and distances tend to be distorted because of artifacts stemming from dimensionality reduction. This makes interpretation of clusters difficult and may lead to distrust in the system. Most existing approaches that counter this drawback explain the distances in the scatterplot (e.g., error visualization) to foster the interpretability of implicit information. Instead, we suggest explicit visualization of the uncertainty related to the information needed for interpretation, specifically the uncertain membership of each object to its cluster. In our approach, we place objects on a grid, and add a continuous ''topography'' in the background, expressing the distribution of uncertainty over all clusters. We motivate our approach from a use case in which we visualize research projects, clustered by topics extracted from scientific abstracts. We hypothesize that uncertainty visualization can increase trust in the system, which we specify as an emergent property of interaction with an interpretable system. We present a first prototype and outline possible procedures for evaluating if and how the uncertainty visualization approach affects interpretability and trust.

description: In this study, degradation behaviors of PA-based backsheets in field modules retrieved from 5 different climatic zones were carefully examined using a suite of advanced spectroscopic and microscopic techniques. Not only large cracks were observed in the outer layers between cells, but also the mudcracking patterns were found in the inner layers of the backsheets, primarily under humid climates. Different degradation mechanisms for each layer of the backsheets were identified based on the chemical formation (acids/imides ratios), which are mainly related to the humidity effect of the environment. Further, nonuniform degradation patterns with a higher degradation level at both surfaces of the backsheets was also manifested. Results have clearly demonstrated that the degradation behaviors of PA backsheets not only depend on the various climates, but also are influenced by the micro-climates resulting from the laminated structures.

description: The influence of Gaussian laser pulses on the transport through molecular wires is investigated within a tight-binding model for spinless electrons including correlation. Motivated by the phenomenon of coherent destruction of tunneling for monochromatic laser fields, situations are studied in which the maximum amplitude of the electric field fulfills the conditions for the destructive quantum effect. It is shown that, as for monochromatic laser pulses, the average current through the wire can be suppressed. For parameters of the model, which do not show a net current without any optical field, a Gaussian laser pulse can establish a temporary current. In addition, the effect of electron correlation on the current is investigated.

Uni- and Multi-modal Uncertainty Visualization in 2D Scalar Field Ensembles
Creators: name: Gebauer, Eike
name: Linsen, Lars
Publisher: name: The Eurographics Association
Year: 2019

description: The aim of uncertainty-aware scalar field visualization is to convey the most likely case, but also the uncertainty associated with it. In scientific simulations, uncertainty can be modeled using an ensemble approach. Statistics are then drawn from the ensemble outcome to compute the most likely case and its uncertainty. However, the statistical distributions do not necessarily need to be uni-modal. We present an approach to visualize uncertain 2D scalar fields that extends existing uni-modal distributions based on colored heightfields and 2D glyphs to multi-modal ones. We compare the approaches by conducting user experiments for both the uni- and multi-modal case.

description: Many advancements have been made in the field of topological mechanics. The majority of the works, however, concerns the topological invariant in a linear theory. We, in this work, present a generic prescription of defining topological indices which accommodates non-linear effects in mechanical systems without taking any approximation. Invoking the tools of differential geometry, a Z-valued quantity in terms of the Poincare-Hopf index, that features the topological invariant of non-linear zero modes (ZMs), is predicted. We further identify one type of topologically protected solitons that are robust to disorders. Our prescription constitutes a new direction of searching for novel topologically protected non-linear ZMs in the future.

description: Smart grids have the potential to significantly increase the share of clean energy on the market. However, to unleash the full potential of this new and constantly evolving technology, well-skilled experts must be trained. The Erasmus+ Project MOST (www.smartgridsmaster.eu/) addresses the need for academia and industry cooperation by designing a master’s degree program on Smart Grid Technologies, solutions and systems. It offers the students the education required to fill the gap between the growing industry demand for specialized smart grid expertise and the skills currently offered by available professionals. The Master’s course will cover not only the smart grid operation fundamentals but also all aspects of smart grid integration. To enable the students testing their knowledge in a real-life environment, living labs and virtual smart grid labs will be developed and integrated into the Smart Grids Master’s degree program. The new master’s program will be available at three leading universities around Europe - the University of Cagliari in Italy, the University of Cyprus, and the University of Western Macedonia in Greece. Moreover, the virtual lab will be accessible by all partnering organizations and the living labs will be installed at the participating universities in Italy, Cyprus and Greece.
Psychological difficulties in new refugee-immigrants as a temporary and transitional display of coping adaptive processes
Creators: name: Adler, Michal
Publisher: name: University of British Columbia
Year: 2010

description: A majority of refugee-immigrants experience a variety of psychological difficulties during their resettlement in a new country. Using a sentence completion method, this study tested a hypothesis that in a majority of refugee-immigrants the manifested difficulties were of temporary and transitional character. Eighty subjects completed 51-item Incomplete Sentence Blank questionnaires: 20 Canadian-born individuals, 20 refugee-immigrants living 1-3 years in Canada, 20 refugee-immigrants living 5-7 years in Canada, and 20 refugee-immigrants living in Canada over 8 years. All refugee-immigrants were of Czechoslovakian origin. Sample groups were matched in sex, age, and education of subjects. The questionnaire was designed to reflect different levels of satisfaction with self, others, and the whole environment. The responses were quantified and evaluated blindly by three independent judges; the higher score was expressing the higher subject's dissatisfaction. Analysis of variance and consequent multiple comparisons showed that the mean score of the sample of refugee-immigrants living in Canada 1-3 years was significantly higher than the mean scores of all other investigated samples; the differences in mean scores between other samples were not significant. In all sample groups, t-tests did not indicate significant differences in scoring between females and males. Fifty-one analyses of variance and multiple comparisons identified separate questionnaire items on which "new" immigrants scored significantly higher than all or some of other sample groups. These items highlighted the adaptive nature of difficulties experienced by the majority of "new" immigrants. Three brief case studies supported these results. Other related findings included suspicious attitudes found mainly in new immigrants, comments on questionnaire forms differentiating between samples, and the topic of "refugee dreams". All findings seem to indicate that for the majority of new refugee-immigrants the psychological difficulties experienced during their resettlement are of temporary and transitional character, a natural expression of their coping adaptive struggles in a new environment.

description: The aim of this deliverable is to define the requirements of the CAPABLE system. These requirements include clinical requirements regarding the clinical scope of decision-support and its content (knowledge base), patient and clinician user needs and requirements, and technical system requirements for the different system components. Following our iterative development approach for the CAPABLE system, this document presents the majority of the functional and non-functional requirements. Once we implement the system in iterations and have users try out the system, additional requirements may be refined and reported at the end of Year 2.

description: A detailed analysis of the wave-mode structure in a bend and its incorporation into a stable algorithm for calculation of the scattering matrix of the bend is presented. The calculations are based on the modal approach. The stability and precision of the algorithm is numerically and analytically analysed. The algorithm enables precise numerical calculations of scattering across the bend. The reflection is a purely quantum phenomenon and is discussed in more detail over a larger energy interval. The behaviour of the reflection is explained partially by a one-dimensional scattering model and heuristic calculations of the scattering matrix for narrow bends. In the same spirit we explain the numerical results for the Wigner-Smith delay time in the bend.
