description: We develop a model of Bose-Einstein condensate dark matter halos with a solitonic core and an isothermal atmosphere based on a generalized Gross-Pitaevskii-Poisson equation [P.H. Chavanis, Eur. Phys. J. Plus 132, 248 (2017)]. This equation provides a heuristic coarse-grained parametrization of the ordinary Gross-Pitaevskii-Poisson equation accounting for violent relaxation and gravitational cooling. It involves a cubic nonlinearity taking into account the self-interaction of the bosons, a logarithmic nonlinearity associated with an effective temperature, and a source of dissipation. It leads to superfluid dark matter halos with a core-halo structure. The quantum potential or the self-interaction of the bosons generates a solitonic core that solves the cusp problem of the cold dark matter model. The logarithmic nonlinearity generates an isothermal atmosphere accounting for the flat rotation curves of the galaxies. The dissipation ensures that the system relaxes towards an equilibrium configuration. In the Thomas-Fermi approximation, the dark matter halo is equivalent to a barotropic gas with an equation of state $P=2πa_s\hbar^2ρ^2/m^3+ρk_B T/m$, where $a_s$ is the scattering length of the bosons and $m$ is their individual mass. We numerically solve the equation of hydrostatic equilibrium and determine the corresponding density profiles and rotation curves. Our model has no free parameter so it is completely predictive. Extension of this model to noninteracting bosons and fermions will be presented in forthcoming papers.

description: The expansion of smart computer-led technologies into new disciplines enables local governments to design and manage their cities with novel smart discourses. Smart Heritage, the convergence of the smart city and heritage disciplines, offers local governments means to regulate and steer these issues. However, due to its novelty, currently, no research exists on the opportunities and trajectory of Smart Heritage within local government. Therefore, the here presented paper reports the opportunities and recommendations for Smart Heritage within local government, drawing on interviews with smart city and heritage advisors from three Australian local councils. It finds opportunities for smart computer-led technologies to design unique economic, place-making, and governance experiences in cities and recommendations that normalise the delivery of local governments' regulatory duties by these technologies. The findings are significant for leading smart technologies further into the practical-political framework of local government and diversifying smart cities' scope while at the same time combining two separated policies.
Can Long-Baseline Neutrino Oscillation Experiments Tell Us about Neutrino Dark Matter?

description: We define the ratio R = (No. of observed electron events)/ (No. of expected muon events - No. of observed muon events) as a measure for relative importance of $ν_μ\to ν_e$ and $ν_μ\to ν_τ$ oscillations which will be measurable in coming long-baseline neutrino experiments. We then argue that if neutrino oscillation is observed with 0.02 < R < 0.87 it implies the rejection of the neutrino dark matter hypothesis. Our argument is valid if neutrinos come with only three flavors without steriles and if they have a hierarchical mass pattern.

description: We consider a quantum dot in the Coulomb blockade regime weakly coupled to current leads and show that in the presence of a magnetic field the dot acts as an efficient spin-filter (at the single-spin level) which produces a spin-polarized current. Conversely, if the leads are fully spin-polarized the up or down state of the spin on the dot results in a large sequential or small cotunneling current, and thus, together with ESR techniques, the setup can be operated as a single-spin memory.

description: The 3D Galactic orbits of stars in the two groups G18-39 and G21-22 pertaining to the Galactic halo have been computed in a Galactic potential including a Galactic bar. The orbits have been related with the orbital structure of resonant orbits on the Galactic plane created by the bar component. We find that the majority of stars in both groups are trapped mainly by two resonant families already studied in a previous analysis. We show that the observed U--V velocity field of the stars in both groups can be naturally explained as a result of their trapping by these two resonant families, taking the angular rotation speed of the bar approximately in the interval 45--60 $\mathrm{km\,s^{-1}\,kpc^{-1}}$. This analysis may help to understand the identification of other known star groups as the possible result of the interactions produced by resonances on stars close to resonant families. For the two groups G18-39 and G21-22 we conclude that the majority of their stars are members of the supergroups of stars in the Galaxy trapped by two resonant families generated by the Galactic bar.

description: The fast dynamics of viscous calcium rubidium nitrate is investigated by depolarized light scattering, neutron scattering and dielectric loss. Fast $β$ relaxation evolves as in calcium potassium nitrate. The dynamic susceptibilities can be described by the asymptotic scaling law of mode-coupling theory with a shape parameter $λ= 0.79$; the temperature dependence of the amplitudes extrapolates to $T_c\simeq 378$ K. However, the frequencies of the minima of the three different spectroscopies never coincide, in conflict with the factorization prediction, indicating that the true asymptotic regime is unreachable.

description: The construction of discrete scalar wave propagation equations in arbitrary inhomogeneous media was recently achieved by using elementary dynamical processes realizing a discrete counterpart of the Huygens principle. In this paper, we generalize this approach to spinor wave propagation. Although the construction can be formulated on a discrete lattice of any dimension, for simplicity we focus on spinors living in 1+1 space-time dimensions. The Dirac equation in the Majorana-Weyl representation is directly recovered by incorporating appropriate symmetries of the elementary processes. The Dirac equation in the standard representation is also obtained by using its relationship with the Majorana-Weyl representation.

description: The transition towards more just and sustainable food systems is a major challenge which requires persuasive policy narratives for motivation and coordination. However, research about how relevant European actor groups view crucial elements of food system transitions is scarce. The consultation on the European Commission's Farm-to-Fork Strategy provided an opportunity to analyze how elements of food system transitions are represented and connected in the policy narratives of European stakeholders. A deductive-inductive content analysis of 164 public responses, using an analytical framework based on the multi-level-perspective of food system transitions, found twelve distinct narratives, mostly focused on agricultural production. Ten of them showed clear connections to three established agricultural policy discourses: neomercantilism, multi-functionalism and market liberalism. While the narratives together provided a comprehensive account of transition drivers, challenges, opportunities and responses, individually they presented rather partial perspectives. For example, market-liberal narratives emphasized the role of value chain actors and “consumer choice”, whereas multifunctionalist narratives called for more regulation. Farmers' associations mainly deployed neomercantilist, NGOs multi-functional and industry representatives market-liberal narratives, revealing dissent on the importance and desirability of change. The findings indicate that shifting the discussion venue away from core agriculture policy arenas broadened entrenched discourses only marginally.

description: We present two novel dynamical features of flux tubes in the Friedberg-Lee model. First the fusion of two (anti-)parallel flux tubes, where we extract a string-string interaction potential which has a qualitative similarity to the nucleon-nucleon potential in the Friedberg-Lee model obtained by Koepf et al. Furthermore we show the dynamical breakup of flux tubes via $q\bar{q}-$particle production and the disintegration into mesons. We find, as a shortcoming of the present realization of the model, that the full dynamical transport approach presented in a previous publication fails to provide the disintegration mechanism in the semiclassical limit. Therefore, in addition, we present here a molecular dynamical approach for the motion of the quarks and show, as a first application, the space-time development of the quarks and their mean-fields for Lund-type string fragmentation processes.

description: A quantum system driven by a weak deterministic force while under strong continuous energy measurement exhibits quantum jumps between its energy levels (Nagourney et al., 1986, Sauter et al., 1986, Bergquist et al., 1986). This celebrated phenomenon is emblematic of the special nature of randomness in quantum physics. The times at which the jumps occur are reputed to be fundamentally unpredictable. However, certain classical phenomena, like tsunamis, while unpredictable in the long term, may possess a degree of predictability in the short term, and in some cases it may be possible to prevent a disaster by detecting an advance warning signal. Can there be, despite the indeterminism of quantum physics, a possibility to know if a quantum jump is about to occur or not? In this dissertation, we answer this question affirmatively by experimentally demonstrating that the completed jump from the ground to an excited state of a superconducting artificial atom can be tracked, as it follows its predictable "flight," by monitoring the population of an auxiliary level coupled to the ground state. Furthermore, the experimental results demonstrate that the jump when completed is continuous, coherent, and deterministic. Exploiting these features, we catch and reverse a quantum jump mid-flight, thus deterministically preventing its completion. This real-time intervention is based on a particular lull period in the population of the auxiliary level, which serves as our advance warning signal. Our results, which agree with theoretical predictions essentially without adjustable parameters, support the modern quantum trajectory theory and provide new ground for the exploration of real-time intervention techniques in the control of quantum systems, such as early detection of error syndromes.

description: This thesis examines figural representations of foreign peoples and places on Roman coinage. An accompanying appendix thoroughly catalogues this imagery between its earliest extant appearance in approximately 138 B.C. and the death of Domitian in 96 A.D. A systematic survey makes it possible to nuance existing narratives of the development of this imagery that privileged the late first and early second centuries A.D. as the key moments of change by revealing considerable diversity and innovation in the earlier period. A second contribution is methodological, highlighting the need for contextual analysis of individual issues to supplement the typological approach that has dominated earlier scholarship. Chapter One focuses on image types produced between 138-31 B.C. This was a particularly vibrant period for the production of these images and the chapter reveals a diverse spectrum of imagery. This contrasts sharply with previous assessments that characterised the period as dominated by images of submission. Chapter Two concentrates on Augustan imperial coinage (31 B.C.-14 A.D.) and identifies a shift towards more consistent usage of submissive imagery. Chapter Three highlights a significant decline in the use of images of foreign peoples and places on imperial coinage minted by the Julio-Claudian successors (14-68 A.D.). Chapter Four identifies a dramatic, albeit inconsistent, resurgence in the use of personifications of foreign peoples and places on coinage minted by competing imperial claimants during the civil wars of 68-69 A.D. Chapter Five focuses on Flavian imperial coinage (69-96 A.D.) and uncovers a significant resurgence in captive imagery. It identifies a new blurring of the lines between the iconographic traditions of captives and personifications of peoples and places. This blending of the two traditions lays important foundations for subsequent imagery on Trajanic imperial coinage.

description: When subjects navigate through spatial environments, grid cells exhibit firing fields that are arranged in a triangular grid pattern. Direct recordings of grid cells from the human brain are rare. Hence, functional magnetic resonance imaging (fMRI) studies proposed an indirect measure of entorhinal grid-cell activity, quantified as hexadirectional modulation of fMRI activity as a function of the subject’s movement direction. However, it remains unclear how the activity of a population of grid cells may exhibit hexadirectional modulation. Here, we use numerical simulations and analytical calculations to suggest that this hexadirectional modulation is best explained by head-direction tuning aligned to the grid axes, whereas it is not clearly supported by a bias of grid cells toward a particular phase offset. Firing-rate adaptation can result in hexadirectional modulation, but the available cellular data is insufficient to clearly support or refute this option. The magnitude of hexadirectional modulation furthermore depends considerably on the subject’s navigation pattern, indicating that future fMRI studies could be designed to test which hypothesis most likely accounts for the fMRI measure of grid cells. Our findings also underline the importance of quantifying the properties of human grid cells to further elucidate how hexadirectional modulations of fMRI activity may emerge.

description: The Koopman–von Neumann equation describes the evolution of a complex-valued wavefunction corresponding to the probability distribution given by an associated classical Liouville equation. Typically, it is defined on the whole Euclidean space. The investigation of bounded domains, particularly in practical scenarios involving quantum-based simulations of dynamical systems, has received little attention so far. We consider the Koopman–von Neumann equation associated with an ordinary differential equation on a bounded domain whose trajectories are contained in the set's closure. Our main results are the construction of a strongly continuous semigroup together with the existence and uniqueness of solutions of the associated initial value problem. To this end, a functional-analytic framework connected to Sobolev spaces is proposed and analyzed. Moreover, the connection of the Koopman–von Neumann framework to transport equations is highlighted.

The thermodynamics and the critical behaviour of the models are studied by the pure-quantum self-consistent harmonic approximation, in order to evaluate the spin and anisotropy dependence of the critical temperatures. Results for thermodynamic quantities are reported and comparison with experimental and numerical simulation data is made. The obtained results allow us to draw a general picture of the subject and, in particular, to estimate the value of the critical temperature for any model belonging to the considered class.

description: An instance of Hamiltonian cycle problem can be solved by converting it to an instance of Travelling salesman problem, assigning any choice of weights to edges of the underlying graph. In this note we demonstrate that, for difficult instances, choosing the edge weights to be the resistance distance between its two incident vertices is often a good choice. We also demonstrate that arguably stronger performance arises from using the inverse of the resistance distance. Examples are provided demonstrating benefits gained from these choices.

description: The classical Lifshitz-Slyozov-Wagner theory of domain coarsening predicts asymptotically self-similar behavior for the size distribution of a dilute system of particles that evolve by diffusional mass transfer with a common mean field. Here we consider the long-time behavior of measure-valued solutions for systems in which particle size is uniformly bounded, i.e., for initial measures of compact support. We prove that the long-time behavior of the size distribution depends sensitively on the initial distribution of the largest particles in the system. Convergence to the classically predicted smooth similarity solution is impossible if the initial distribution function is comparable to any finite power of distance to the end of the support. We give a necessary criterion for convergence to other self-similar solutions, and conditional stability theorems for some such solutions. For a dense set of initial data, convergence to any self-similar solution is impossible.

description: Motivation Accurate quantitative information about protein abundance is crucial for understanding a biological system and its dynamics. Protein abundance is commonly estimated using label-free, bottom-up mass spectrometry (MS) protocols. Here, proteins are digested into peptides before quantification via MS. However, missing peptide abundance values, which can make up more than 50% of all abundance values, are a common issue. They result in missing protein abundance values, which then hinder accurate and reliable downstream analyses. Results To impute missing abundance values, we propose PEPerMINT, a graph neural network model working directly on the peptide level that flexibly takes both peptide-to-protein relationships in a graph format as well as amino acid sequence information into account. We benchmark our method against 11 common imputation methods on 6 diverse datasets, including cell lines, tissue, and plasma samples. We observe that PEPerMINT consistently outperforms other imputation methods. Its prediction performance remains high for varying degrees of missingness, different evaluation approaches, and differential expression prediction. As an additional novel feature, PEPerMINT provides meaningful uncertainty estimates and allows for tailoring imputation to the user’s needs based on the reliability of imputed values.

description: Neutrino induced deep inelastic charm production off strange sea partons in the nucleon is studied in the framework of the MSbar fixed flavor factorization scheme. The momentum (z) distributions of the produced D mesons as calculated in the next-to-leading order QCD analysis are presented and compared to their leading order counterparts. Perturbative stability within this formalism is demonstrated and the compatibility of recent next-to-leading order (NLO) strange quark distributions with available dimuon data is investigated. Our NLO (MSbar) results provide, for the first time, the tools required for a consistent and complete NLO (MSbar) analysis of charged current dimuon data in order to extract the strange sea density in NLO. It is furthermore shown that the absolute predictions of radiatively (dynamically) generated strange sea densities are in agreement with all present measurements.

description: Recognizing that no central authority can combat climate change, scholars have pointed to the potential of polycentric governance in tackling climate change. Yet, empirical evidence for such a claim is scarce, particularly in the Global South. This study analyzes the characteristics, promises, and pitfalls of polycentric governance to promote climate mitigation efforts in three Indian states. Our contribution is twofold: (1) conceptually, we propose a framework to investigate the promises and pitfalls of polycentric climate governance in a federalist system with a particular focus on aspects of scaling and institutionalization, and (2) empirically, we compare solar power development across three Indian states with favorable conditions for solar power but varying performance. Based on a qualitative analysis of interviews and documents, we show how state governments with different party backgrounds have been vital in implementing policy changes and overcoming political barriers. Still, very few bottom-up initiatives exist and were successfully institutionalized.

Moire structures in twisted bilayer graphene studied by transmission electron microscopy

description: We investigate imaging of moire structures in free-standing twisted bilayer graphene (TBG) carried out by transmission electron microscopy (TEM) in diffraction and in-line Gabor holography modes. Electron diffraction patterns of TBG acquired at typical TEM electron energies of 80 - 300 keV exhibit the diffraction peaks caused by diffraction on individual layers. However, diffraction peaks at the scattering angles related to the periodicity of the moire structure have not been observed in such diffraction patterns. We show that diffraction on moire structure can create intense diffraction peaks if the energy of the probing electrons is very low, in the range of a few tens of eV. Experimental diffraction patterns of TBG acquired with low-energy electrons of 236 eV exhibiting peaks attributed to the moire structure periodicity are shown. In holography mode, the intensity of the wave transmitted through the sample and measured in the far-field can be enhanced or decreased depending on the atomic arrangement, as for example AA or AB stacking. Thus, a decrease of intensity in the far-field must not necessarily be associated with some absorption inside the sample but can simply be a result of a particular atomic arrangement. We believe that our findings can be important for exploiting graphene as a support in electron imaging.

description: Lung diseases are one of the leading causes of global mortality. Advances in induced pluripotent stem cell (iPSC) differentiation have enabled the creation of bronchiolar and alveolar lung organoids, advancing research on lung conditions. Traditional Matrigel encapsulation, reliant on the spontaneous assembly and propagation of cells with limited external intervention, often results in variability and low reproducibility. The absence of hyaluronic acid (HA) in Matrigel, a key lung extracellular matrix component, limits bronchiolar and alveolar cell differentiation, reducing the efficacy and reproducibility of iPSC-derived organoid generation. To address this, a novel hybrid hydrogel combining HA and 23% Matrigel, inspired by the natural lung environment, is developed. This hydrogel offers improved biochemical support and viscoelastic properties, significantly accelerating organoid development. Within eight days, the hydrogel produces uniformly sized organoids containing both bronchiolar and alveolar epithelial cells. Increased levels of active mechanosensors and transducers, including PIEZO1, Integrin, and Myosin, suggest that the hydrogel's altered viscoelasticity triggers a mechanotransduction cascade. This bioinspired hydrogel provides a robust, fast model for biomedical research, facilitating rapid drug screening, respiratory disease treatment studies, and surfactant trafficking investigations. Furthermore, it enables the exploration of underlying biomechanical mechanisms to enhance the controllability of organoid generation and maturation.

description: Bioarchaeological studies provide a valuable contribution to the understanding of the economy and activities of prehistoric populations in mountain regions. The Late Bronze Age in the Caucasus is an epoch of fundamental transformations that is accompanied by the development of a semi-stationary pastoral economy and ultimately by the emergence of combined mountain agriculture. So far, only a few archaeozoological assemblages from this period have been published. The site of Ransyrt-1 in the North Caucasus offers a substantial collection of bone material from the remains of a mountain sanctuary. Analysis of the animal remains as well as preliminary isotopic analyses of strontium, oxygen, and carbon shed light on animal exploitation at this site. Comparisons with slightly later settlements in the North and South Caucasus illustrate the development of intensive livestock management strategies in the Late Bronze Age in this region at the interface between Southwest Asia and the Eurasian steppe.
