description: Using public data (Forbes Global 2000) we show that the asset sizes for the largest global firms follow a Pareto distribution in an intermediate range, that is ``interrupted'' by a sharp cut-off in its upper tail, where it is totally dominated by financial firms. This flattening of the distribution contrasts with a large body of empirical literature which finds a Pareto distribution for firm sizes both across countries and over time. Pareto distributions are generally traced back to a mechanism of proportional random growth, based on a regime of constant returns to scale. This makes our findings of an ``interrupted'' Pareto distribution all the more puzzling, because we provide evidence that financial firms in our sample should operate in such a regime. We claim that the missing mass from the upper tail of the asset size distribution is a consequence of shadow banking activity and that it provides an (upper) estimate of the size of the shadow banking system. This estimate -- which we propose as a shadow banking index -- compares well with estimates of the Financial Stability Board until 2009, but it shows a sharper rise in shadow banking activity after 2010. Finally, we propose a proportional random growth model that reproduces the observed distribution, thereby providing a quantitative estimate of the intensity of shadow banking activity.

Fermi Rules Out the IC/CMB Model for the Large Scale Jet X-ray Emission of 3C 273

description: The X-ray emission mechanism in large-scale jets of powerful radio quasars has been a source of debate in recent years, with two competing interpretations: either the X-rays are of synchrotron origin, arising from a different electron energy distribution than that producing the radio to optical synchrotron component, or they are due to inverse Compton scattering of cosmic microwave background photons (IC/CMB) by relativistic electrons in a powerful relativistic jet with bulk Lorentz factor Gamma ~ 10-20. These two models imply radically different conditions in the large-scale jet in terms of jet speed, kinetic power, and maximum energy of the particle acceleration mechanism, with important implications for the impact of the jet on the large-scale environment. A large part of the X-ray origin debate has centered on the well-studied source 3C 273. Here we present new observations from Fermi which put an upper limit on the gamma-ray flux from the large-scale jet of 3C 273 that violates at a confidence greater that 99.9% the flux expected from the IC/CMB X-ray model found by extrapolation of the UV to X-ray spectrum of knot A, thus ruling out the IC/CMB interpretation entirely for this source when combined with previous work. Further, this upper limit from Fermi puts a limit on the Doppler beaming factor of at least delta < 9, assuming equipartition fields, and possibly as low as delta < 5, assuming no major deceleration of the jet from knots A through D1.

Effective Field Theory of Dark Energy: a Dynamical Analysis

description: The effective field theory (EFT) of dark energy relies on three functions of time to describe the background dynamics. The viability of these functions is investigated here by means of a thorough dynamical analysis. While the system is underdetermined, and one can always find a set of functions reproducing any expansion history, we are able to determine general compatibility conditions for these functions by requiring a viable background cosmology. In particular, we identify a set of variables that allows us to transform the non-autonomous system of equations into an infinite-dimensional one characterized by a significant recursive structure. We then analyze several autonomous sub-systems, obtained truncating the original one at increasingly higher dimension, that correspond to increasingly general models of dark energy and modified gravity. Furthermore, we exploit the recursive nature of the system to draw some general conclusions on the different cosmologies that can be recovered within the EFT formalism and the corresponding compatibility requirements for the EFT functions. The machinery that we set up serves different purposes. It offers a general scheme for performing dynamical analysis of dark energy and modified gravity models within the model independent framework of EFT; the general results, obtained with this technique, can be projected into specific models, as we show in one example. It also can be used to determine appropriate ansatze for the three EFT background functions when studying the dynamics of cosmological perturbations in the context of large scale structure tests of gravity.

Olympic Games, the pandemic of physical inactivity and exercise as medicine
Creators: name: Lange, Klaus W.
Publisher: name: Journal of Disease Prevention and Health Promotion
Year: 2022

description: The current pandemic of a sedentary lifestyle and physical inactivity is closely related to the global increase in obesity and other chronic diseases. More than five million deaths per year have been estimated to be due to inactive lifestyles. Tackling the threat of the physical inactivity pandemic is fundamental for the future of effective, affordable and sustainable health systems. Global public health action is therefore urgently needed. The staging of Olympic Games has often been justified by the promise of a physical activity and health legacy. However, the claim that the Olympics result in beneficial lifestyle changes is not supported by studies conducted following major multi-sport events. Nevertheless, the Beijing Winter Olympics 2022 may become an exception to the rule of a failed Olympic health legacy. A policy of the Chinese government has set the target of attracting more than 300 million people to winter sport activities. The policy entails the construction of a new winter sport infrastructure as well as attempts to support the existing national fitness programme and to bring healthier lifestyles to the general population. In consequence, China has seen a substantial growth in participation in ice and snow activities. However, this promising development will not be self-propelling, and the government-led top-down implementation of winter sport needs to be supplemented by long-term policy interventions. Changing the complex behaviour of physical activity requires an effective population strategy as well long-term commitment, coordinated policy and integrated investment. Chinese sports experts have called for a greater emphasis on promoting sports participation to boost national health initiatives. Thus, China has shifted its sports focus from winning medals to improving mass fitness. The current Chinese health agenda, emphasising the prevention of chronic disease, may generate innovative solutions, including harnessing Olympic effects, and may set an example for public health systems worldwide.

Music and health in times of the COVID-19 pandemic

Year: 2022

description: Elevated stress levels resulting from fear of the coronavirus, physical distancing measures and economic problems can be expected to cause psychological trauma and detrimental effects on mental health. Music appears to have salutogenetic effects, contributing to wellbeing and supporting health, and may fulfill the functions of mood regulation and social cohesion. Playing or creating music, dancing and listening to music can activate various brain regions involved in cognitive and emotional functions, thereby possibly exerting beneficial effects on physiological and psychological health. Participation in musical activities can provide an effective means of alleviating stress, anxiety and depressed mood. Music may also serve as a proxy for social interaction and may be capable of generating new or stronger social bonds. Preliminary evidence suggests a role of making and listening to music in meeting social needs and improving emotional self-regulation and coping during coronavirus-related lockdowns. Music-related behaviours appear to aid in stress-management, and their potential therapeutic value in the current pandemic deserves further consideration and warrants more systematic research. Since the capacity of music to modulate the behaviour of individuals is supported by various studies, music may be utilised as a communication tool and its effectiveness in promoting adherence to public health advice should be investigated.

description: In this paper, we systematically examine the stability and dynamics of vortices under the effect of a phenomenological dissipation used as a simplified model for the inclusion of the effect of finite temperatures in atomic Bose-Einstein condensates. An advantage of this simplified model is that it enables an analytical prediction that can be compared directly (and favorably) to numerical results. We then extend considerations to a case of considerable recent experimental interest, namely that of a vortex dipole and observe good agreement between theory and numerical computations in both the stability properties (eigenvalues of the vortex dipole stationary states) and the dynamical evolution of such configurations.

Rudolf Virchow and disease prevention and health promotion in the 21st century
Creators: name: Lange, Klaus W.
Publisher: name: Journal of Disease Prevention and Health Promotion
Year: 2021

description: The German pathologist and politician Rudolf Virchow played a pivotal role in promoting social medicine and improving public health in the 19th century. Virchow’s main achievements include his characterisation of medicine as a social science as well as a biological science. His fundamental goals included the founding of the practice of medicine on the exact sciences as well as the prevention of disease and promotion of health through social and political action. According to Virchow, the remit of medicine was not merely to treat disease but also to contribute to the health of the entire population. Today, disease prevention and health promotion should become priorities in global and national political agendas and investment decisions. The key factors contributing to the global pandemic of non-communicable diseases are unhealthy lifestyles, with high-calorie diets, insufficient physical exercise, tobacco smoking and alcohol use. These lifestyle factors also contribute to the susceptibility to severe acute respiratory syndrome coronavirus type 2 infection and a more severe course of coronavirus disease 2019. Prevention of the development of non-communicable and age-related diseases would reduce the future demand on healthcare systems. Interventions capable of slowing ageing and reducing the number of disability-adjusted life years may have a greater benefit than those targeted at individual disease. Decisive political leadership is required to motivate significant changes in health improvement in respect of both infectious and non-communicable diseases. Governments worldwide need to pay serious attention to the wellbeing of the people and should institute lasting and meaningful changes at population level.

description: ECH capacities give obstructions to symplectically embedding one symplectic four-manifold with boundary into another. We compute the ECH capacities of a large family of symplectic four-manifolds with boundary, called "concave toric domains". Examples include the (nondisjoint) union of two ellipsoids in $\mathbb{R}^4$. We use these calculations to find sharp obstructions to certain symplectic embeddings involving concave toric domains. For example: (1) we calculate the Gromov width of every concave toric domain; (2) we show that many inclusions of an ellipsoid into the union of an ellipsoid and a cylinder are "optimal"; and (3) we find a sharp obstruction to ball packings into certain unions of an ellipsoid and a cylinder.

description: The nearby Sun-like star HD 19467 shows a subtle radial velocity (RV) acceleration of -1.37+/-0.09 m/s/yr over an 16.9 year time baseline (an RV trend), hinting at the existence of a distant orbiting companion. We have obtained high-contrast adaptive optics images of the star using NIRC2 at Keck Observatory and report the direct detection of the body that causes the acceleration. The companion, HD 19467 B, is dK=12.57+/-0.09 mag fainter than its parent star (contrast ratio of 9.4e-6), has blue colors J-K_s=-0.36+/-0.14 (J-H=-0.29+/-0.15), and is separated by 1.653+/-0.004" (51.1+/-1.0 AU). Follow-up astrometric measurements obtained over an 1.1 year time baseline demonstrate physical association through common parallactic and proper motion. We calculate a firm lower-limit of m>51.9^{+3.6}_{-4.3}Mjup for the companion mass from orbital dynamics using a combination of Doppler observations and imaging. We estimate a model-dependent mass of m=56.7^{+4.6}_{-7.2}Mjup from a gyrochronological age of 4.3^{+1.0}_{-1.2} Gyr. Isochronal analysis suggests a much older age of $9\pm1$ Gyr, which corresponds to a mass of m=67.4^{+0.9}_{-1.5}Mjup. HD 19467 B's measured colors and absolute magnitude are consistent with a late T-dwarf [~T5-T7]. We may infer a low metallicity of [Fe/H]=-0.15+/-0.04 for the companion from its G3V parent star. HD 19467 B is the first directly imaged benchmark T-dwarf found orbiting a Sun-like star with a measured RV acceleration.

Anisotropic diffusive transport: connecting microscopic scattering and macroscopic transport properties
Creators: name: Alerstam, Erik
Publisher: name: arXiv
Year: 2013
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: This work concerns the modeling of radiative transfer in anisotropic turbid media using diffusion theory. A theory for the relationship between microscopic scattering properties (i.e., an arbitrary differential scattering cross-section) and the macroscopic diffusion tensor, in the limit of independent scatterers, is presented. The theory is accompanied by a numerical method capable of performing the calculations. In addition, a boundary condition appropriate for modeling systems with anisotropic radiance is derived. It is shown that anisotropic diffusion theory, when based on these developments, indeed can describe radiative transfer in anisotropic turbid media. More specifically, it is reported that solutions to the anisotropic diffusion equation are in excellent agreement with Monte Carlo simulations, both in steady-state and time-domain. This stands in contrast to previous work on the topic, where inadequate boundary conditions and/or incorrect relations between microscopic scattering properties and the diffusion tensor have caused disagreement between simulations and diffusion theory. The present work thus falsify previous claims that anisotropic diffusion theory cannot describe anisotropic radiative transfer, and instead open for accurate quantitative diffusion-based modeling of anisotropic turbid materials.

description: We study the covariant version of the quark-parton model, in which the general rules of the angular momentum composition are accurately taken into account. We demonstrate how these rules affect the relativistic interplay between the quark spins and orbital angular momenta, which collectively contribute to the proton spin. The spin structure functions $g_{1}$ and $g_{2}$ corresponding to the many-quark state $J=1/2$ are studied and it is shown they satisfy constraints and relations well compatible with the available experimental data including proton spin content $ΔΣ\lesssim1/3$. The suggested Lorentz invariant 3D approach for calculation of the structure functions is compared with the approach based on the conventional collinear parton model.

description: The experiment will test the hypothesis that the motor induced motor inhibition effect is mostly, if not solely, due to motor inhibition rather than a shift in attention. This can be achieved by having half the participants perform the act that induces the inhibition and the act that measures the inhibition WITH THE SAME EFFECTOR (i.e., finger) and the other half perform these two tasks with DIFFERENT EFFECTORS (i.e., different fingers).

Monogamy inequalities for the EPR paradox and quantum steering

Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Monogamy inequalities for the way bipartite EPR steering can be distributed among N systems are derived. One set of inequalities is based on witnesses with two measurement settings, and may be used to demonstrate correlation of outcomes between two parties, that cannot be shared with more parties. It is shown that the monogamy for steering is directional. Two parties cannot independently demonstrate steering of a third system, using the same two-setting steering witness, but it is possible for one party to steer two independent systems. This result explains the monogamy of two-setting Bell inequality violations, and the sensitivity of the continuous variable (CV) EPR criterion to losses on the steering party. We generalise to m settings. A second type of monogamy relation gives the quantitative amount of sharing possible, when the number of parties is less than or equal to m, and takes a form similar to the Coffman-Kundu-Wootters (CKW) relation for entanglement. The results enable characterisation of the tripartite steering for CV Gaussian systems and qubit GHZ and W states.

description: The joint statistics of partial sums of ordered random variables (RVs) are often needed for the accurate performance characterization of a wide variety of wireless communication systems. A unified analytical framework to determine the joint statistics of partial sums of ordered independent and identically distributed (i.i.d.) random variables was recently presented. However, the identical distribution assumption may not be valid in several real-world applications. With this motivation in mind, we consider in this paper the more general case in which the random variables are independent but not necessarily identically distributed (i.n.d.). More specifically, we extend the previous analysis and introduce a new more general unified analytical framework to determine the joint statistics of partial sums of ordered i.n.d. RVs. Our mathematical formalism is illustrated with an application on the exact performance analysis of the capture probability of generalized selection combining (GSC)-based RAKE receivers operating over frequency-selective fading channels with a non-uniform power delay profile. We also discussed a couple of other sample applications of the generic results presented in this work.

We also show that most quivers Q of finite mutation type admit only one non-degenerate potential up to weak right equivalence. In this case, the isomorphism class of P(Q,S) depends only on Q and not on S.

description: People spontaneously coordinate their bodies during an interaction by adopting the same posture or copying each other’s expressions. Prior studies conducted with neurotypical populations show that such interpersonal coordination facilitates social interaction quality and affiliation. Yet, we know relatively little about how contextual and individual differences act on the effects of interpersonal coordination on interaction quality and affiliation. Another point underexplored in the literature is the coordination of facial expressions, rather than other behaviours, between people. Facial expressions carry a wealth of information about intensions, perceptions, feelings and emotions. It is crucial to attain mutuality in these aspects for smooth and rewarding social interactions. This study aims to fill in these empirical gaps in our knowledge across two aims (see Hypotheses section below).
Maximal zero textures of the inverse seesaw with broken $μτ$ symmetry

description: The inverse neutrino seesaw, characterised by only one source of lepton number violation at an ultralight $O$(keV) scale and observable new phenomena at TeV energies accessible to the LHC, is considered. Maximal zero textures of the $3\times 3$ lighter and heavier Dirac mass matrices of neutral leptons, appearing in the Lagarangian for such an inverse seesaw, are studied within the framework of $μτ$ symmetry in a specified weak basis. That symmetry ensures the identity of the positions of maximal zeros of the heavy neutrino mass matrix and its inverse. It then suffices to study the maximal zeros of the lighter Dirac mass matrix and those of the inverse of the heavier one since they come in a product. The observed absence of any unmixed neutrino flavour and the assumption of no strictly massless physical neutrino state allow only eight $4$-zero $\times$ $4$-zero, eight $4$-zero $\times$ $6$-zero and eight $6$-zero $\times$ $4$-zero combinations. The additional requirement of leptogenesis is shown to eliminate the last sixteen textures. The surviving eight $4$-zero $\times$ $4$-zero textures are subjected to the most general explicit $μτ$ symmetry breaking terms in the Lagrangian in order to accommodate the nonzero value of $θ_{13}$ in the observed range. A full diagonalisation is then carried out. On numerical comparison with all extant and relevant neutrino (antineutrino) data, seven of these eight combination textures in five neutrino matrix forms are found to be allowed, leading to five distinct neutrino mass matrices. Two of these permit only a normal (and the other three only an inverted) mass ordering of the light neutrinos.

description: Genetic drift at the frontiers of two-dimensional range expansions of microorganisms can frustrate local cooperation between different genetic variants, demixing the population into distinct sectors. In a biological context, mutualistic or antagonistic interactions will typically be asymmetric between variants. By taking into account both the asymmetry and the interaction strength, we show that the much weaker demixing in three dimensions allows for a mutualistic phase over a much wider range of asymmetric cooperative benefits, with mutualism prevailing for any positive, symmetric benefit. We also demonstrate that expansions with undulating fronts roughen dramatically at the boundaries of the mutualistic phase, with severe consequences for the population genetics along the transition lines.

description: We study the late-time Integrated Sachs-Wolfe (ISW) effect in $f(R)$ gravity using N-body simulations. In the $f(R)$ model under study, the linear growth rate is larger than that in general relativity (GR). This slows down the decay of the cosmic potential and induces a smaller ISW effect on large scales. Therefore, the $\dotΦ$ (time derivative of the potential) power spectrum at $k<0.1h$/Mpc is suppressed relative to that in GR. In the non-linear regime, relatively rapid structure formation in $f(R)$ gravity boosts the non-linear ISW effect relative to GR, and the $\dotΦ$ power spectrum at $k>0.1h$/Mpc is increased (100$\%$ greater on small scales at $z=0$). We explore the detectability of the ISW signal via stacking supercluster and supervoids. The differences in the corresponding ISW cold or hot spots are $\sim 20\%$ for structures of $\sim 100$Mpc/$h$. Such differences are greater for smaller structures, but the amplitude of the signal is lower. The high amplitude of ISW signal detected by Granett et al. can not explained in the $f(R)$ model. We find relatively big differences between $f(R)$ and GR in the transverse bulk motion of matter, and discuss its detectability via the relative frequency shifts of photons from multiple lensed images.

description: The past three decades have shown dramatic progress in the ability to manipulate and coherently control the motion of atoms. This exquisite control offers the prospect of a new generation of inertial sensors with unprecedented sensitivity and accuracy, which will be important for both fundamental and applied science. In this article, we review some of our recent results regarding the application of atom interferometry to inertial measurements using compact, mobile sensors. This includes some of the first interferometer measurements with cold $^{39}$K atoms, which is a major step toward achieving a transportable, dual-species interferometer with rubidium and potassium for equivalence principle tests. We also discuss future applications of this technology, such as remote sensing of geophysical effects, gravitational wave detection, and precise tests of the weak equivalence principle in Space.

description: We examine uncertainties in the analysis of the reactor neutrino anomaly, wherein it is suggested that only about 94% of the emitted antineutrino flux was detected in short baseline experiments. We find that the form of the corrections that lead to the anomaly are very uncertain for the 30% of the flux that arises from forbidden decays. This uncertainty was estimated in four ways, is as large as the size of the anomaly, and is unlikely to be reduced without accurate direct measurements of the antineutrino flux. Given the present lack of detailed knowledge of the structure of the forbidden transitions, it is not possible to convert the measured aggregate fission beta spectra to antineutrino spectra to the accuracy needed to infer an anomaly. Neutrino physics conclusions based on the original anomaly need to be revisited, as do oscillation analyses that assumed that the antineutrino flux is known to better than approximately 4%.

description: Collective coherent scattering of laser light by an ensemble of polarizable point particles creates long range interactions, whose properties can be tailored by choice of injected laser powers, frequencies and polarizations. We use a transfer matrix approach to study the forces induced by non-interfering fields of orthogonal polarization or different frequencies in a 1D geometry and find long range self-ordering of particles without a prescribed order. Adjusting laser frequencies and powers allows to tune inter-particle distances and provides a wide range of possible dynamical couplings not accessible in usual standing light wave geometries with prescribed order. In this work we restrict the examples to two frequencies and polarisations but the framework also allows to treat multicolour light beams with random phases. These dynamical effects should be observable in existing experimental setups with effective 1D geometries such as atoms or nanoparticles coupled to the field of an optical nanofibre or transversely trapped in counterpropagating Gaussian beams.

description: Prior research shows people will describe their ingroup in a similar manner to how they describe themselves. In our prior two studies, we show that people will do this for minimal groups and will generalize to non-evaluated traits using similarity relations (Study 1), and this effect of self-projection to ingroup is greater when comparing against high status outgroup (UCLA) than a low status outgroup (CSU LA) (Study 2). Here, we attempt to extend these self-anchoring effects to racial/ethnic groups and to determine whether if the comparison against a higher status majority or a comparison against another minority group differently influences the tendency to self-anchor.
Changement structurel et création d'emploi au Maroc
Creators: name: EL KHAZZANI, Driss
Publisher: name: Zenodo

Subjects: emploi ; jeunes ; élasticité ; productivité ; changement structurel

description: Le présent article a pour objectif d’estimer l’élasticité de l’emploi -global et des jeunes- par rapport à la croissance économique. Il apporte également un éclairage sur le changement structurel de l’économie marocaine et ses implications sur le processus de création (destruction) de l’emploi. Les données mobilisées proviennent du Haut-Commissariat au Plan et portent sur la période 1999-2019. L’approche adoptée s’appuie sur une modélisation économétrique, par la méthode des MCO, pour estimer l’élasticité et une décomposition arithmétique de la productivité du travail.

Les résultats aboutissent à un coefficient d’élasticité globale est de 0,27 et de -0,37 pour l’emploi des jeunes. Au plan sectoriel, trois branches affichent des coefficients d’élasticité élevés. Les résultats montrent également que la productivité du travail a progressé à un rythme modéré de 2,98% en moyenne annuelle, durant la période sous revue. Les gains de productivité intra branche sont prépondérants et portent l’essentiel de la croissance de la productivité du travail, le changement structurel représente un peu moins du quart de l’amélioration de la productivité. Les résultats indiquent que l’économie marocaine connait une inertie structurelle de ses activités et une dynamique structurelle d’ampleur limitée.
Hidden Hazards: Microplastics in Plants and Their Impact on Our Food Chain

description: The discovery of microplastics in plants has added a new dimension to the plastic pollution crisis, affecting not just oceans and rivers but also agricultural systems and food safety. These tiny particles, typically under 5 mm, originate from degraded plastic waste, microbeads, and synthetic fibers. They permeate soil, water, and air, persisting for centuries and posing long-term environmental threats. Microplastics disrupt plant growth, degrade soil health, and can be absorbed by crops, ultimately entering the human food chain. Microplastic contamination in fruits and vegetables raises concerns for human health, underscoring the broader global issue of plastic pollution. With plastic waste projected to reach 12 billion metric tons by 2050, the presence of microplastics in plants highlights the urgent need for systemic change. This includes reducing plastic usage, improving waste management practices, and conducting further research on mitigating microplastics' effects on ecosystems. Immediate, collective action is essential to address this growing environmental issue and protect human health and the planet.

description: Let $d \geq 3$ be an integer. It is known that the number of edges of the edge polytope of the complete graph with $d$ vertices is $d(d-1)(d-2)/2$. In this paper, we study the maximum possible number $μ_d$ of edges of the edge polytope arising from finite simple graphs with $d$ vertices. We show that $μ_{d}=d(d-1)(d-2)/2$ if and only if $3 \leq d \leq 14$. In addition, we study the asymptotic behavior of $μ_d$. Tran--Ziegler gave a lower bound for $μ_d$ by constructing a random graph. We succeeded in improving this bound by constructing both a non-random graph and a random graph whose complement is bipartite.

description: Nachtrag von Dr. Erika Schachinger (27. Oktober 2012): "Die Errichtung der Schlossfassaden-Attrappe 1993/94 auf dem Schlossplatz-Areal in Berlin Mitte auf Veranlassung von Herrn von Boddien aus Hamburg hat mich überzeugt, dass die Nachbildung der Schlossfassade in den Ausmaßen des damaligen Baukörpers tatsächlich zu einer Beruhigung des Stadtraumes führt. Erstens: Die offene Flanke zum Lustgraten wird geschlossen. Drei Seiten dieses Platzes haben ihren alten, von Kriegsschäden befreiten Baubestand behalten: der Dom, das alte Museum und das Zeughaus. Zweitens: Auf der anderen Seite des Schlossplatz-Areals erhielt die Breite Straße - durch die Fassadenattrappe - eine Fassung. Sie hatte nun ein Ziel un zerfloss nicht wie ein wild gewordener Fluss. Drittens: Auch der bekannten Straße Unter den Linden fehlt bekanntlich das Ziel, zu dem sie führen soll. Der besondere Blickpunkt ergab sich ja gerade daraus, dass die Straße schräg auf das Schloss hin zulief. Heute kann ich sagen: Mein Herz und mein Verstand sagen ja zu dem Bauprojekt."
