Can we predict fjord basin water renewals?

description: The water in the basin of sill fjords is renewed ocasionally. In some fjords, this renewal occurs irregularly while on others it has a more regular character. Independently of the renewal period, the renewal mechanism is thought to be common to all sill fjords: subsurface water outside of the fjord mouth lifted above the sill depth will trigger a renewal, provided that the lifted water mass is denser than the water in the basin. In Western Norway, the northerly, upwelling favourable winds that occur during Spring/Summer, provide a forcing for the uplifting of the isopycnals and bring dense, subsurface water to the upper water column, thereby creating the conditions for renewals to occur (Helle, 1980).

The renewal of sill fjord basins is an important aspect of the fjord ecological condition because it supplies oxygen rich water to the fjord basin, whose oxygen is consumed by the degradation of organic matter during the stagnant periods. Byfjorden (Figure 1) is the urban fjord in Bergen. It is heavily urbanized and has been consistenly showing lower oxygen levels in its basin (Figure 2), which has ecological implications (Johansen et al., 2018).

Byfjorden’s basin water is regularly renewed between the months of March and August, which makes it an attractive choice for the application of Deep Learning to predict basin water renewal in sill fjords. However, although Byfjorden’s observational period is long when compared to other fjords, there are significant gaps in the time series and the sampling frequency in most cases is suboptimal. In spite of these limitations, it is interesting to study the renewal process in the context of the atmospheric and hydrographic setting of the Norwegian coast.

description: Gravitational waveforms for compact binary coalescences (CBCs) have been invaluable for detections by the LIGO-Virgo collaboration. They are obtained by a combination of semi-analytical models and numerical simulations. So far systematic errors arising from these procedures appear to be less than statistical ones. However, the significantly enhanced sensitivity of the new detectors that will become operational in the near future will require waveforms to be much more accurate. This task would be facilitated if one has a variety of cross-checks to \emph{evaluate} accuracy, particularly in the regions of parameter space where numerical simulations are sparse. Currently errors are estimated by comparing the candidate waveforms with the numerical relativity (NR) ones, which are taken to be exact. The goal of this paper is to propose a qualitatively different tool. We show that full non-linear general relativity (GR) imposes an infinite number of sharp constraints on the CBC waveforms. These can provide clear-cut measures to evaluate the accuracy of candidate waveforms against exact GR, help find systematic errors, and also provide external checks on NR simulations themselves.

description: We provide a rigorous and asymptotically exact expression of the mutual information of translationally invariant free fermionic lattice systems in a Gibbs state. In order to arrive at this result, we introduce a novel framework for computing determinants of Töplitz operators with smooth symbols, and for treating Töplitz matrices with system size dependent entries. The asymptotically exact mutual information for a partition of the 1D lattice satisfies an area law, with a prefactor which we compute explicitly. As examples, we discuss the fermionic XX model in one dimension and free fermionic models on the torus in higher dimensions in detail. Special emphasis is put on the discussion of the temperature dependence of the mutual information, scaling like the logarithm of the inverse temperature, hence confirming an expression suggested by conformal field theory. We also comment on the applicability of the formalism to treat open systems driven by quantum noise. In the appendix, we derive useful bounds to the mutual information in terms of purities. Finally, we provide a detailed error analysis for finite system sizes. This analysis is valuable in its own right for the abstract theory of Töplitz determinants.

description: Das Ziel dieser Studie ist es, Faktoren zu identifizieren, die für eine möglichst erfolgreiche Anwendung von Fördermaßnahmen für erneuerbare Energien im Strommarkt besonders wichtig sind. Dabei bestätigt sich die Grundannahme, dass neben der prinzipiellen Entschei-dung für ein bestimmtes Förderinstrumentarium, v.a. die äußeren Rahmenbedingungen, die grundsätzliche Ausgestaltung von Fördermodellen sowie instrumentenspezifische Detailre- gelungen maßgeblich für den Erfolg verantwortlich sind. Hinsichtlich der Rahmenbedingungen werden dabei fünf Makrofaktoren identifiziert. Dies sind geographische bzw. die Ausgangsbedingungen der Energiepolitik eines Landes betref-fende, sowie ökonomische, politische, technische und kognitive Faktoren. Darüber hinaus ist es die jeweilige Ausgestaltung einer Fördermaßnahme, die über die ge-wünschte Effektivität entscheidet. Wiederum werden diesbezüglich fünf zentrale Kriterien i-dentifiziert, die den Erfolg eines Förderinstruments mitbestimmen. Dies sind die langfristige Planungs- und Investitionssicherheit, die technologiedifferenzierte Vergütung, die standort- abhängige Vergütung, die Rechts- und Wettbewerbskonformität, sowie die institutionelle Be-herrschbarkeit eines jeden Förderinstruments. Schließlich sind auch zahlreiche Detailregelungen innerhalb des jeweiligen Förderansatzes für dessen Erfolg mit entscheidend, wie z. B. eine degressive und zeitlich befristete Ausrich-tung der Vergütung bei Einspeisemodellen.
description: It is the aim of this study to identify success conditions of instruments for the promotion of re-newable energies in the electricity market. The basic assumption that the success of a cer-tain promotion instrument mainly depends on the (external) framework conditions and on its general and specific design is proved true. Concerning the framework conditions five macro factors are identified. These include geo-graphical factors respectively the individual starting position in energy policy as well as eco-nomical, political, technical and cognitive factors. Furthermore the general design of a promotion measure is responsible for its grade of effec-tiveness. Again five main criteria are identified which influence the success of a promotion instrument in a crucial way: long-term security for planning and investments, technology spe-cific payment, location specific payment, compatibility with law and competition and adminis-trative manageability. Finally, several specific shapings within a respective promotion model are decisive for its successful deployment for example a degressive and temporary limited payment in a feed-in system.

description: Information-aware connected and automated vehicles (CAVs) have drawn great attention in recent years due to its potentially significant positive impacts on roadway safety and operational efficiency. In this paper, we conduct an in-depth review of three basic and key interrelated aspects of a CAV: sensing and communication technologies, human factors, and information-aware controller design. First, different vehicular sensing and communication technologies and their protocol stacks, to provide reliable information to the information-aware CAV controller, are thoroughly discussed. Diverse human factor issues, such as user comfort, preferences, and reliability, to design the CAV systems for mass adaptation are also discussed. Then, different layers of a CAV controller (route planning, driving mode execution, and driving model selection) considering human factors and information through connectivity are reviewed. In addition, critical challenges for the sensing and communication technologies, human factors, and information-aware controller are identified to support the design of a safe and efficient CAV system while considering user acceptance and comfort. Finally, promising future research directions of these three aspects are discussed to overcome existing challenges to realize a safe and operationally efficient CAV.

description: Das südöstliche Siebenstromland in Kasachstan ist reich an Hinterlassenschaften der reiterkriegernomadischen skytho-sakischen Kulturverbände des 1. Jahrtausends v. Chr. Vor allem sind sie durch Gräberfelder mit mächtigen Großkurganen bekannt. Eine Kartierung der Nekropolen erlaubte es bestimmte Landschaftsmarker festzustellen, die eine führende Rolle bei der Errichtung ritueller Plätze der früheisenzeitlichen sakischen Elite spielten, die gleichzeitig als zentrale Orte des kollektiven Gedächtnisses und der kulturellen Selbstidentifikation der Saken galten. Die Untersuchung sowohl der internen Struktur der Gräberfelder als auch der Kurganenform und ihrer Peripherie zeigte bestimmte architektonische Muster auf, die einerseits verschiedene rituelle Handlungen repräsentierten und andererseits eine mögliche soziale Stratigraphie der sakischen Gesellschaft zum Ausdruck brachte. Es konnten zudem zahlreiche, wahrscheinlich gleichzeitig zu den sakischen Nekropolen bestehende Siedlungsplätze erkannt werden. Die Siedlungen hatten in unterschiedlichen Gebieten des Untersuchungsgebietes verschiedene Rollen und zeugen von verschiedenen Wirtschaftsformen, die vom sesshaften Ackerbau bis zur nomadisch betriebenen Viehzucht reichen. Die Erforschung der vorangehenden Bronzezeit im 2. Jahrtausend v. Chr., die im Untersuchungsgebiet durch die sog. Kul’saj-Gruppe repräsentiert ist, hilft den Kulturwandel von der Bronze- zur Früheisenzeit besser nachzuzeichnen.

description: Berenstein, Maldacena, and Nastase have proposed, as a limit of the strong form of the AdS/CFT correspondence, that string theory in a particular plane wave background is dual to a certain subset of operators in the N=4 super-Yang-Mills theory. Even though this is a priori a strong/weak coupling duality, the matrix elements of the string theory Hamiltonian, when expressed in gauge theory variables, are analytic in the 't Hooft coupling constant. This allows one to conjecture that, like the masses of excited string states, these can be recovered using perturbation theory in Yang-Mills theory. In this paper we identify the difference between the generator of scale transformations and a particular U(1) R-symmetry generator as the operator dual to the string theory Hamiltonian for nonvanishing string coupling. We compute its matrix elements and find that they agree with the string theory prediction provided that the state-operator map is modified for nonvanishing string coupling. We construct this map explicitly and calculate the anomalous dimensions of the new operators. We identify the component arising from the modification of the state-operator map with the contribution of the string theory contact terms to the masses of string states.

description: Optical fibers play a key role in many different fields of science and technology. In particular, fibers with a diameter of several micrometers are intensively used in photonics. For these applications, it is often important to precisely know and control the fiber radius. Here, we demonstrate a novel technique to determine the local radius variation of a 30-micrometer diameter silica fiber with sub-Ångström precision with axial resolution of several tens of micrometers over a fiber length of more than half a millimeter. Our method relies on taking an image of the fiber's whispering-gallery modes (WGMs). In these WGMs, the speed of light propagating along the fiber axis is strongly reduced. This enables us to determine the fiber radius with a significantly enhanced precision, far beyond the diffraction limit. By exciting different axial modes, we verify the precision and reproducibility of our method and demonstrate that we can achieve a precision better than 0.3 Å. The method can be generalized to other experimental situations where slow light occurs and, thus, has a large range of potential applications in the realm of precision metrology and optical sensing.

description: This paper investigates the network-assisted full-duplex (NAFD) cell-free millimeter-wave (mmWave) networks, where the distribution of the transmitting access points (T-APs) and receiving access points (R-APs) across distinct geographical locations mitigates cross-link interference, facilitating the attainment of a truly flexible duplex mode. To curtail deployment expenses and power consumption for mmWave band operations, each AP incorporates a hybrid digital-analog structure encompassing precoder/combiner functions. However, this incorporation introduces processing intricacies within channel estimation and precoding/combining design. In this paper, we first present a hybrid multiple-input multiple-output (MIMO) processing framework and derive explicit expressions for both uplink and downlink achievable rates. Then we formulate a power allocation problem to maximize the weighted bidirectional sum rates. To tackle this non-convex problem, we develop a collaborative multi-agent deep reinforcement learning (MADRL) algorithm called multi-agent twin delayed deep deterministic policy gradient (MATD3) for NAFD cell-free mmWave networks. Specifically, given the tightly coupled nature of both uplink and downlink power coefficients in NAFD cell-free mmWave networks, the MATD3 algorithm resolves such coupled conflicts through an interactive learning process between agents and the environment. Finally, the simulation results validate the effectiveness of the proposed channel estimation methods within our hybrid MIMO processing paradigm, and demonstrate that our MATD3 algorithm outperforms both multi-agent deep deterministic policy gradient (MADDPG) and conventional power allocation strategies.

description: We study the quantization of coupled Kähler-Einstein (CKE) metrics, namely we approximate CKE metrics by means of the canonical Bergman metrics, so called the ``balanced metrics''. We prove the existence and weak convergence of balanced metrics for the negative first Chern class, while for the positive first Chern class, we introduce some algebro-geometric obstruction which interpolates between the Donaldson-Futaki invariant and Chow weight. Then we show the existence and weak convergence of balanced metrics on CKE manifolds under the vanishing of this obstruction. Moreover, restricted to the case when the automorphism group is discrete, we also discuss approximate solutions and a gradient flow method towards the smooth convergence.

description: The main objective of this article is to study the viable compact stellar structures in non-Riemannian geometry, i.e., $f(\mathbb{Q},T)$ theory, where $\mathbb{Q}$ defines the non-metricity and $T$ represents trace of the stress-energy tensor. In this perspective, we consider a static spherical metric with anisotropic matter configuration to examine the geometry of considered compact stars. A specific model of this theory is used to derive the explicit expressions of energy density and pressure components that govern the relationship between matter and geometry. The unknown parameters are evaluated by using the continuity of inner and outer spacetimes to examine the configuration of spherical stellar structures. Physical parameters such as fluid characteristics, energy constraints and equation of state parameters are analyzed to examine the viability of the considered stellar objects. Further, we use Tolman-Oppenheimer-Volkoff equation, sound speed and adiabatic index methods to analyze the equilibrium state and stability of the proposed stellar objects. The rigorous analysis and satisfaction of necessary conditions lead to the conclusion that the stellar objects studied in this framework are viable and stable.

description: For an arbitrary complex algebraic variety which is not necessarily pure dimensional, the intersection complex can be defined as the direct sum of the Deligne-Goresky-MacPherson intersection complexes of each irreducible component. We give two axiomatic topological characterizations of the middle perversity direct sum intersection complex, one stratification dependent and the other stratification independent. To accomplish this, we show that this direct sum intersection complex can be constructed using Deligne's construction in the more general context of topologically stratified spaces. A consequence of these characterizations is the invariance of this direct sum intersection complex under homeomorphisms.

description: Recent work studying triadic closure in undirected graphs has drawn attention to the distinction between measures that focus on the "center" node of a wedge (i.e., length-2 path) vs. measures that focus on the "initiator," a distinction with considerable consequences. Existing measures in directed graphs, meanwhile, have all been center-focused. In this work, we propose a family of eight directed closure coefficients that measure the frequency of triadic closure in directed graphs from the perspective of the node initiating closure. The eight coefficients correspond to different labelled wedges, where the initiator and center nodes are labelled, and we observe dramatic empirical variation in these coefficients on real-world networks, even in cases when the induced directed triangles are isomorphic. To understand this phenomenon, we examine the theoretical behavior of our closure coefficients under a directed configuration model. Our analysis illustrates an underlying connection between the closure coefficients and moments of the joint in- and out-degree distributions of the network, offering an explanation of the observed asymmetries. We also use our directed closure coefficients as predictors in two machine learning tasks. We find interpretable models with AUC scores above 0.92 in class-balanced binary prediction, substantially outperforming models that use traditional center-focused measures.

description: The Event Horizon Telescope (EHT) is taking the first images of black holes resolved at horizon scales to measure their shadows and probe accretion physics. A promising avenue for testing the hypothesis that astrophysical black holes are described by the Kerr solution to Einstein's equations is to compare the size and shape of the shadow a black hole casts on the surrounding emission to the predictions of the Kerr metric. We develop here an efficient parametric framework to perform this test. We carry out ray-tracing simulations for several parametrized non-Kerr metrics to create a large data set of non-Kerr shadows that probe the allowed parameter space for the free parameters of each metric. We then perform principal components analysis (PCA) on this set of shadows and show that only a small number of components are needed to accurately reconstruct all shadows within the set. We further show that the amplitude of the PCA components are smoothly related to the free parameters in the metrics, and therefore, that these PCA components can be fit to EHT observations in order to place constraints on the free parameters of these metrics that will help quantify any potential deviations from the Kerr solution.

description: To date, New Sanctuary Movement (NSM) scholars have largely focused on the movement’s federal legislative efforts to characterize the movement as purely domestic, comprised exclusively of organizations and individuals based in the United States, calling for legal reform in the United States. Unfortunately, this characterization is somewhat simplified. In reality, the NSM consists of organizations that have sought to provide basic legal and humanitarian services to refugees from Central America, aside from any federal legislative demands. This thesis thus demonstrates that the NSM comprises a diverse set of transnational actors that have mobilized for legal change at the federal and local levels, connected refugees from Central America to legal aid providers, provided necessary survival supplies to refugees, and helped provide services that help refugees acclimatize to their lives in the United States. Applying theories on transnational social movements and social movement emergence and formation, this work (1) traces the historical growth of the NSM from the early 2000s to the current day, under President Donald Trump and (2) draws on empirical research to reveal the broad coalition of actors that are part of the NSM today.

description: SCFD1 (sec1 family domain containing 1) was recently shown to function in autophagosome-lysosome fusion, and multiple studies have demonstrated the regulatory impacts of acetylation (a post-translational modification) on macroautophagy/autophagy. Here, we demonstrate that both acetylation- and phosphorylation-dependent mechanisms control SCFD1ʹs function in autophagosome-lysosome fusion. After detecting a decrease in the extent of SCFD1 acetylation under autophagy-stimulated conditions, we found that KAT2B/PCAF catalyzes the acetylation of residues K126 and K515 of SCFD1; we also showed that these two residues are deacetylated by SIRT4. Importantly, we showed that AMPK-controlled SCFD1 phosphorylation strongly disrupts the capacity of SCFD1 to interact with KAT2B, thus ensuring that the SCFD1 acetylation level remains low. Finally, we demonstrated that SCFD1 acetylation inhibits autophagic flux, specifically by blocking STX17-SNAP29-VAMP8 SNARE complex formation. Thus, our study reveals a mechanism through which phosphorylation and acetylation modifications of SCFD1 mediate SNARE complex formation to regulate autophagosome maturation.ACLY: ATP citrate lyase; CREB: cAMP responsive element binding protein; EBSS: nutrient-deprivation medium; EP300: E1A binding protein p300; KAT5/TIP60: lysine acetyltransferase 5; HOPS: homotypic fusion and protein sorting; MS: mass spectroscopy; SCFD1: sec1 family domain containing 1; SM: Sec1/Munc18; SNARE: soluble N-ethylmaleimide-sensitive factor attachment protein receptor; UVRAG: UV radiation resistance associated

description: The trajectories of the clusters $η$ Cha, $ε$ Cha and Cha I, Cha II, constructed backward in time, have been studied. We concluded that the hypothesis about the joint formation of all four of these clusters from one molecular cloud cannot be completely excluded. However, 10-15 Myr ago, all these four clusters were located at approximately the same height above the plane of the Galaxy. Thus, the gas-dust clouds from which all these four clusters were formed were located on one broad front. It is possible that the appearance of the Cha I, Cha II, $ε$ Cha and $η$ Cha clusters may be associated with the impact on such a front of shock waves formed after supernova explosions in the Scorpius-Centauri association. New estimates of the kinematic ages of the clusters Cha I and Cha II are obtained as $0.12\pm0.19$ and $0.05\pm0.15$, respectively. It is shown that the minimum size of the Cha I-north and Cha I-south clusters corresponded to the time of $0.55\pm0.24$ Myr and $0.04\pm0.18$ Myr ago, respectively, and approximately 1.5 Myr ago the distance between the trajectories of these two groupings was minimal.

description: This paper concerns the analysis and implementation of a novel iterative staggered scheme for quasi-static brittle fracture propagation models, where the fracture evolution is tracked by a phase field variable. The model we consider is a two-field variational inequality system, with the phase field function and the elastic displacements of the solid material as independent variables. Using a penalization strategy, this variational inequality system is transformed into a variational equality system, which is the formulation we take as the starting point for our algorithmic developments. The proposed scheme involves a partitioning of this model into two subproblems; phase field and mechanics, with added stabilization terms to both subproblems for improved efficiency and robustness. We analyze the convergence of the proposed scheme using a fixed point argument, and find that under a natural condition, the elastic mechanical energy remains bounded, and, if the diffusive zone around crack surfaces is sufficiently thick, monotonic convergence is achieved. Finally, the proposed scheme is validated numerically with several bench-mark problems.

Majorana corner flat bands in two-dimensional second-order topological superconductors

description: In this paper we find that confining a second-order topological superconductor with a harmonic potential leads to a proliferation of Majorana corner modes. As a consequence, this results in the formation of Majorana corner flat bands which have a fundamentally different origin from that of the conventional mechanism. This is due to the fact that they arise solely from the one-dimensional gapped boundary states of the hybrid system that become gapless without the bulk gap closing under the increase of the trapping potential magnitude. The Majorana corner states are found to be robust against the strength of the harmonic trap and the transition from Majorana corner states to Majorana flat bands is merely a smooth crossover. As a harmonic trap can potentially be realized in heterostructures, this proposal paves a way to observe these Majorana corner flat bands in an experimental context.

description: Omnidirectional cameras are extensively used in various applications to provide a wide field of vision. However, they face a challenge in synthesizing novel views due to the inevitable presence of dynamic objects, including the photographer, in their wide field of view. In this paper, we introduce a new approach called Omnidirectional Local Radiance Fields (OmniLocalRF) that can render static-only scene views, removing and inpainting dynamic objects simultaneously. Our approach combines the principles of local radiance fields with the bidirectional optimization of omnidirectional rays. Our input is an omnidirectional video, and we evaluate the mutual observations of the entire angle between the previous and current frames. To reduce ghosting artifacts of dynamic objects and inpaint occlusions, we devise a multi-resolution motion mask prediction module. Unlike existing methods that primarily separate dynamic components through the temporal domain, our method uses multi-resolution neural feature planes for precise segmentation, which is more suitable for long 360-degree videos. Our experiments validate that OmniLocalRF outperforms existing methods in both qualitative and quantitative metrics, especially in scenarios with complex real-world scenes. In particular, our approach eliminates the need for manual interaction, such as drawing motion masks by hand and additional pose estimation, making it a highly effective and efficient solution.

description: Nous prouvons l'existence de formules de réciprocité pour des sommes de la forme $\sum_{m=1}^{k-1} f(\frac{m}k) \cot(π\frac{mh}k)$, où $f$ est une fonction $C^1$ par morceaux, qui met en évidence un phénomène d'alternance qui n'apparaît pas dans le cas classique où $f(x) = x$. Nous déduisons des majorations de ces sommes en termes du développement en fraction continue de $h/k$. We prove the existence of reciprocity formulae for sums of the form $\sum_{m=1}^{k-1}f(\frac{m}{k})\cot(π\frac{m h}k)$ where $f$ is a piecewise $C^1$ function, featuring an alternating phenomenon not visible in the classical case where $f(x)=x$. We deduce bounds for these sums in terms of the continued fraction expansion of $h/k$.

description: We present a method to reconstruct indoor and outdoor static scene geometry and appearance from an omnidirectional video moving in a small circular sweep. This setting is challenging because of the small baseline and large depth ranges, making it difficult to find ray crossings. To better constrain the optimization, we estimate geometry as a signed distance field within a spherical binoctree data structure and use a complementary efficient tree traversal strategy based on a breadth-first search for sampling. Unlike regular grids or trees, the shape of this structure well-matches the camera setting, creating a better memory-quality trade-off. From an initial depth estimate, the binoctree is adaptively subdivided throughout the optimization; previous methods use a fixed depth that leaves the scene undersampled. In comparison with three neural optimization methods and two non-neural methods, ours shows decreased geometry error on average, especially in a detailed scene, while significantly reducing the required number of voxels to represent such details.

description: We analyze the long time behavior of initial value problems that model a process where particles of type A and B diffuse in some substratum and react according to $nA+nB\to C$. The case n=1 has been studied before; it presents nontrivial behavior on the reactive scale only. In this paper we discuss in detail the cases $n>3$, and prove that they show nontrivial behavior on the reactive and the diffusive length scale.
