description: Consciousness research has long been dominated by neuron-centric models, but emerging evidence suggests that astrocytes—metabolic and neuromodulatory gatekeepers—play a crucial role in regulating conscious access. This paper proposes a paradigm shift by integrating the Global Workspace Theory (GWT) and the Free Energy Principle (FEP) through the lens of astrocytic precision weighting and metabolic sustainment. Rather than treating consciousness as mere information integration, this framework argues that temporal coherence and metabolic constraints dictate which neural signals persist long enough to enter awareness. Astrocytes, by modulating prediction error weighting, oscillatory stability, and neuroenergetic support, serve as the missing link between hierarchical predictive processing and global ignition events. This astrocyte-centered model reframes consciousness as a metabolically constrained, time-structured process, providing a new foundation for understanding subjective experience, altered states, and potential artificial implementations of self-sustaining awareness.

description: Spatiotemporal mode-locking in a laser with anomalous dispersion is investigated. Mode-locked states with varying modal content can be observed, but we find it difficult to observe highly multimode states. We describe the properties of these mode-locked states and compare them to the results of numerical simulations. Prospects for the generation of highly-multimode states and lasers based on multimode soliton formation are discussed.
Solvable Periodic Anderson Model with Infinite-Range Hatsugai-Kohmoto Interaction: Ground-states and beyond

description: In this paper we introduce a solvable two-orbital/band model with infinite-range Hatsugai-Kohmoto interaction, which serves as a modified periodic Anderson model. Its solvability results from strict locality in momentum space, and is valid for arbitrary lattice geometry and electron filling. Case study on a one-dimension ($1D$) chain shows that the ground-states have Luttinger theorem-violating non-Fermi-liquid-like metallic state, hybridization-driven insulator and interaction-driven featureless Mott insulator. The involved quantum phase transition between metallic and insulating states belongs to the universality of Lifshitz transition, i.e. change of topology of Fermi surface or band structure. Further investigation on $2D$ square lattice indicates its similarity with the $1D$ case, thus the findings in the latter may be generic for all spatial dimensions. We hope the present model or its modification may be useful for understanding novel quantum states in $f$-electron compounds, particularly the topological Kondo insulator SmB$_{6}$ and YbB$_{12}$.

description: The power grid is going through significant changes with the introduction of renewable energy sources and incorporation of smart grid technologies. These rapid advancements necessitate new models and analyses to keep up with the various emergent phenomena they induce. A major prerequisite of such work is the acquisition of well-constructed and accurate network datasets for the power grid infrastructure. In this paper, we propose a robust, scalable framework to synthesize power distribution networks which resemble their physical counterparts for a given region. We use openly available information about interdependent road and building infrastructures to construct the networks. In contrast to prior work based on network statistics, we incorporate engineering and economic constraints to create the networks. Additionally, we provide a framework to create ensembles of power distribution networks to generate multiple possible instances of the network for a given region. The comprehensive dataset consists of nodes with attributes such as geo-coordinates, type of node (residence, transformer, or substation), and edges with attributes such as geometry, type of line (feeder lines, primary or secondary) and line parameters. For validation, we provide detailed comparisons of the generated networks with actual distribution networks. The generated datasets represent realistic test systems (as compared to standard IEEE test cases) that can be used by network scientists to analyze complex events in power grids and to perform detailed sensitivity and statistical analyses over ensembles of networks.

description: Dieser Beitrag thematisiert die Wirksamkeit von Lehrer*innenfortbildungen sowie wahrgenommene Erwartungen aus der Perspektive der Fortbildner*innen. Die spärliche Forschungslage zu diesem Thema führte zu der Projektidee, den Fokus der Forschung auf die Fortbildner*innen zu legen. Ein Team von vier Pädagogischen Hochschulen in Österreich konzipierte im Jahr 2018 ein gemeinsames Forschungsprojekt, in welchem mittels qualitativer Interviews untersucht werden sollte, welche Faktoren zu einer gelungenen Fortbildung beitragen. Gestützt auf die Studien von Lipowsky wurde ein Modell entwickelt, welches die vier Ebenen der Wirksamkeit von Fortbildung mit der Unterscheidung von Selbstbild (Sicht der Fortbildner*innen) und Fremdbild (wahrgenommene Erwartungen der Teilnehmer*innen und Auftraggeber*innen) abbildet. Die Ergebnisse weisen darauf hin, dass die Wirksamkeitsfaktoren, welche von Fortbildner*innen genannt werden, großteils mit den wahrgenommenen Erwartungen der Teilnehmenden und Auftraggeber*innen übereinstimmen. So ist es aus Sicht der Fortbildner*innen nötig, anspruchsvolle, vielfältige Lernumgebungen sowie gut geplante und gut strukturierte Veranstaltungen zu schaffen, um so Fortbildungsveranstaltungen für die Lehrpersonen motivierend gestalten zu können. Auch die freiwillige Teilnahme und die Möglichkeit des informellen Austausches bei Fortbildungsveranstaltungen erhöhen deren Wirksamkeit. Input-, Erprobungs- und Reflexionsphasen sowie eine Nachbetreuung beispielsweise in professionellen Lerngemeinschaften oder auf digitalen Plattformen wirken sich positiv auf den Transfer von Wissen, Erfahrung und Ideen an den Schulstandorten aus. Die Bedeutung von Qualität der Fortbildungsformate und der Fachkompetenz der Lehrer*innenfortbildner*innen kann als zentrales Ergebnis genannt werden. Diese Forschungsbefunde sollten künftig in die möglichst erfolgsversprechende Gestaltung der Formate (u.a. zumindest mehrere Teilnehmer*innen eines Schulstandortes sowie mehrteilige Veranstaltungen) sowie in das Recruiting und die Professionalisierung der Fortbildner*innen einfließen.

description: To more thoroughly study the effects of radiative forces on the orbits of small, astronomical bodies, we introduce the Yarkovsky effect into REBOUNDx, an extensional library for the N-body integrator REBOUND. Two different versions of the Yarkovsky effect (the "Full Version" and the "Simple Version") are available for use, depending on the needs of the user. We provide demonstrations for both versions of the effect and compare their computational efficiency with another previously implemented radiative force. In addition, we show how this effect can be used in tandem with other features in REBOUNDx by simulating the orbits of asteroids during the asymptotic giant branch phase of a 2 $M_{\odot}$ star. This effect is made freely available for use with the latest release of REBOUNDx.

description: We study the variation of the shape of the proton intensity-time profiles in simulated gradual Solar Energetic Particle (SEP) events with the relative observer's position in space with respect to the main direction of propagation of an interplanetary (IP) shock. Using a three-dimensional (3D) magnetohydrodynamic (MHD) code to simulate such a shock, we determine the evolution of the downstream-to-upstream ratios of the plasma variables at its front. Under the assumption of an existing relation between the normalized ratio in speed across the shock front and the injection rate of shock-accelerated particles, we model the transport of the particles and we obtain the proton flux profiles to be measured by a grid of 18 virtual observers located at 0.4 and 1.0 AU, with different latitudes and longitudes with respect to the shock nose. The differences among flux profiles are the result of the way each observer establishes a magnetic connection with the shock front, and we find that changes in the observer's latitude may result in intensity changes of up to one order of magnitude at both radial distances considered here. The peak intensity variation with the radial distance for the pair of observers located at the same angular position is also derived. This is the first time that the latitudinal dependence of the peak intensity with the observer's heliocentric radial distance has been quantified within the framework of gradual SEP event simulations.

We describe a general algorithm to determine the cardinality of the set of orbits $\mathrm{Hom}(\mathsf{F}_r, \mathrm{SL}_n(\mathbb{F}_q))/\mathrm{SL}_n(\mathbb{F}_q)$. Our first main theorem is the implementation of this algorithm in the case $n=2$. As an application, we determine the $E$-polynomial of the character variety $\mathrm{Hom}(\mathsf{F}_r, \mathrm{SL}_2(\mathbb{C}))//!/\mathrm{SL}_2(\mathbb{C})$, and of its smooth and singular locus. Thus we determine the Euler characteristic of these spaces.

description: Signal temporal logic (STL) is a powerful formalism for specifying various temporal properties in dynamical systems. However, existing methods, such as mixed-integer programming and nonlinear programming, often struggle to efficiently solve control problems with complex, long-horizon STL specifications. This study introduces \textit{STLCCP}, a novel convex optimization-based framework that leverages key structural properties of STL: monotonicity of the robustness function, its hierarchical tree structure, and correspondence between convexity/concavity in optimizations and conjunctiveness/disjunctiveness in specifications. The framework begins with a structure-aware decomposition of STL formulas, transforming the problem into an equivalent difference of convex (DC) programs. This is then solved sequentially as a convex quadratic program using an improved version of the convex-concave procedure (CCP). To further enhance efficiency, we develop a smooth approximation of the robustness function using a function termed the \textit{mellowmin} function, specifically tailored to the proposed framework. Numerical experiments on motion planning benchmarks demonstrate that \textit{STLCCP} can efficiently handle complex scenarios over long horizons, outperforming existing methods.

Broader view of bimetric MOND

description: All existing treatments of bimetric MOND (BIMOND) -- a class of relativistic versions of MOND -- have dealt with a rather restricted sub-class: The Lagrangian of the interaction between the gravitational degrees of freedom -- the two metrics -- is a function of a certain {\it single} scalar argument built from the difference in connections of the two metrics. I show that the scope of BIMOND is much richer: The two metrics can couple through several scalars to give theories that all have a "good" nonrelativistic (NR) limit -- one that accounts correctly, a-la MOND, for the dynamics of galactic systems, {\it including gravitational lensing}. This extended-BIMOND framework exhibits a qualitative departure from the way we think of MOND at present, as encapsulated, in all its aspects, by one "interpolating function" of one acceleration variable. After deriving the general field equations, I pinpoint the subclass of theories that satisfy the pivotal requirement of a good NR limit. These involve three independent, quadratic scalar variables. In the NR limit these scalars all reduce to the same acceleration scalar, and the NR theory then does hinge on one function of a {\it a single} acceleration variable -- representing the NR MOND "interpolating function", whose form is largely dictated by the observed NR galactic dynamics. However, these scalars behave differently, in different relativistic contexts. So, the full richness of the multi-variable Lagrangian, as it enters cosmology, for example, is hardly informed by what we learn from observations of galactic dynamics. In this paper, I present the formalism, with some generic examples. I also consider some cosmological solutions where the two metrics are small departures from one Friedman-Lemaitre-Robertson-Walker metric. This may offer a framework for describing cosmology within the extended BIMOND.

Time reversal for photoacoustic tomography based on the wave equation of Nachman, Smith and Waag

description: The goal of \emph{photoacoustic tomography} (PAT) is to estimate an \emph{initial pressure function} $φ$ from pressure data measured at a boundary surrounding the object of interest. This paper is concerned with a time reversal method for PAT that is based on the dissipative wave equation of Nachman, Smith and Waag\cite{NaSmWa90}. This equation has the advantage that it is more accurate than the \emph{thermo-viscous} wave equation. For simplicity, we focus on the case of one \emph{relaxation process}. We derive an exact formula for the \emph{time reversal image} $\I$, which depends on the \emph{relaxation time} $τ_1$ and the \emph{compressibility} $κ_1$ of the dissipative medium, and show $\I(τ_1,κ_1)\toφ$ for $κ_1\to 0$. This implies that $\I=φ$ holds in the dissipation-free case and that $\I$ is similar to $φ$ for sufficiently small compressibility $κ_1$. Moreover, we show for tissue similar to water that the \emph{small wave number approximation} $\I_0$ of the time reversal image satisfies $\I_0 = η_0 *_\x φ$ with $\hat η_0(|\k|)\approx const.$ for $|\k|<< \frac{1}{c_0\,τ_1}$. For such tissue, our theoretical analysis and numerical simulations show that the time reversal image $\I$ is very similar to the initial pressure function $φ$ and that a resolution of $σ\approx 0.036\cdot mm$ is feasible (in the noise-free case).

description: In seinem Abgesang auf das Industriezeit­alter erzählt der Historiker Lutz Raphael „von gestern aus“. Das Gestern wird zur Erzähl­perspektive, es gilt, seine Reichweite zu er­fassen, sein Enden zu begreifen, das Heute nicht als Vorbote eines neuen Morgen zu untersuchen, sondern als Verstummen einer Vielzahl von Akteuren, denen die einstige Gegenwart der Industrialisierung zur selbst­ verständlichen Zukunft wurde. Raphael treibt nicht die Hoffnung, dass sich das Neue an der Bruchstelle zum Alten zu erkennen gibt, er sieht in der methodischen Vorliebe für „Anfänge des Neuen in den sozialen Phänomenen der jüngsten Vergangenheit“ letztlich eine „Obsession für Fortschritts- beziehungsweise Wachstumserzählungen, während Prozesse des Schrumpfens, gar Verschwindens sozialer Gruppen oder Ge­bilde tendenziell mit Schweigen oder Des­interesse belegt werden“. Heute ist Schluss mit gestern, wir erleben stattdessen eine „Peripherisierung von Sozialräumen“ der Industriegesellschaft. Und wenn das Ges­tern aufscheint, dann als „Retrotopie“ ei­nes nostalgischen Rückzugs in das Eigene. Doch die Maschine, sie verschwindet nicht. In den neo-industriellen Visionen autono­mer Systeme und künstlicher Intelligenzen kündigt sich keinesfalls ein Abschied von der Maschine an, im Gegenteil. Die Wahr­nehmung der Gegenwart als Maschinen­zeitalter verbindet uns mit den Auseinan­dersetzungen vorheriger Zeiten. Vielleicht hilft der Vergleich, auf jeden Fall scheint es sinnvoll, unsere Erfahrung radikalen tech­nologischen Wandels nicht allein aus sich selbst heraus verstehen zu wollen. Die 1920er Jahre im internationalen Saar­gebiet stehen für eine Schlüsselphase in der Industrialisierung der Region, in der nicht zuletzt die Elektrifizierung das gesamte ge­sellschaftliche Leben erfasst. In den Ma­schinenräumen der Arbeitswelten entste­hen auch neue Lebenswelten. Die Welt öffnet sich; und sie ist fremd. Der Dialog der Momente 2020/1920 bringt nicht nur das Vertraute, nostalgisch Gerahmte wie­der in den Blick. Sondern auch das Fremde.

description: There have been many papers suggesting that the parameter of the generalized uncertainty principle should be negative rather than positive in some specific scenarios, and the negative parameter can remove the minimum length. However, the minimum length is a model-independent feature of quantum gravity and it should not be affected by the specific scenarios. In order to solve this contradiction, we derive a new generalized uncertainty principle to reflect a fixed and unified minimum length in both cases of positive and negative parameters.

description: The transverse field Ising chain (TFIC) model is ideally suited for testing the fundamental ideas of quantum phase transitions, because its well-known $T=0$ ground state can be extrapolated to finite temperatures. Nonetheless, the lack of appropriate model materials hindered the past effort to test the theoretical predictions. Here we map the evolution of quantum fluctuations in the TFIC based on Nuclear Magnetic Resonance (NMR) measurements of CoNb$_2$O$_6$, and demonstrate the finite temperature effects on quantum criticality for the first time. From the temperature dependence of the $^{93}$Nb longitudinal relaxation rate $1/T_1$, we identify the renormalized classical, quantum critical, and quantum disordered scaling regimes in the temperature ($T$) vs. transverse magnetic field ($h_{\perp}$) phase diagram. Precisely at the critical field $h_{\perp}^{c}=5.25 \pm 0.15$ T, we observe a power-law behavior, $1/T_{1} \sim T^{-3/4}$, as predicted by quantum critical scaling. Our parameter-free comparison between the data and theory reveals that quantum fluctuations persist up to as high as $T \sim 0.4 J$, where the intra-chain exchange interaction $J$ is the only energy scale of the problem.

description: Urgent theoretical progress is needed in order to provide an estimate in the Standard Model of the recent measurement by LHCb of direct CP violation in charm-meson two-body decays. Rescattering effects must be taken into account for a meaningful theoretical description of the amplitudes involved in such category of observables, as signaled by the presence of large strong phases. We discuss the computation of the latter effects based on a two-channel coupled dispersion relation, which exploits isospin-zero phase-shifts and inelasticity parameterizations of data coming from the rescattering processes $ ππ\to ππ$, $ πK \to πK $, and $ ππ\to K \overline{K} $. The determination of the subtraction constants of the dispersive integrals relies on the leading contributions to the transition amplitudes from the $ 1/N_C $ counting, where $N_C$ is the number of QCD colours. Furthermore, we use the measured values of the branching ratios to help in selecting the non-perturbative inputs in the isospin limit, from which we predict values for the CP asymmetries. We find that the predicted level of CP violation is much below the experimental value.

description: We study Fluctuation Relations (FRs) for dynamics that are anomalous, in the sense that the diffusive properties strongly deviate from the ones of standard Brownian motion. We first briefly review the concept of transient work FRs for stochastic dynamics modeled by the ordinary Langevin equation. We then introduce three generic types of dynamics generating anomalous diffusion: Lévy flights, long-time correlated Gaussian stochastic processes and time-fractional kinetics. By combining Langevin and kinetic approaches we calculate the work probability distributions in the simple nonequilibrium situation of a particle subject to a constant force. This allows us to check the transient FR for anomalous dynamics. We find a new form of FRs, which is intimately related to the validity of fluctuation-dissipation relations. Analogous results are obtained for a particle in a harmonic potential dragged by a constant force. We argue that these findings are important for understanding fluctuations in experimentally accessible systems. As an example, we discuss the anomalous dynamics of biological cell migration both in equilibrium and in nonequilibrium under chemical gradients.

description: This study tested unexpected vection and postural instability accounts of cybersickness by having 30 participants play a commercial virtual reality (VR) simulation (“Mission-ISS”), while wearing head-mounted displays (HMD) for up to 14 minutes, or until the first symptoms of sickness. Of these participants, 23 reported symptoms, while 7 did not. We found that the likelihood and severity of cybersickness increased when the vection experienced was unexpected. Spontaneous standing sway before entering VR was also found to differ depending on whether the participant became sick or remained well. In addition, the severity of their sickness appeared to be related to changes in their sway during VR. When these vection and sway-based predictors were examined together, unexpected vection emerged as the strongest predictor of cybersickness. Taken together with the findings of recent studies, the research shows that unexpected vection predicts experiences of cybersickness across a variety of different virtual environments, virtual navigation methods and types of simulated movement.

description: As an effective form of narrative visualization, visual data stories are widely used in data-driven storytelling to communicate complex insights and support data understanding. Although important, they are difficult to create, as a variety of interdisciplinary skills, such as data analysis and design, are required. In this work, we introduce Erato, a human-machine cooperative data story editing system, which allows users to generate insightful and fluent data stories together with the computer. Specifically, Erato only requires a number of keyframes provided by the user to briefly describe the topic and structure of a data story. Meanwhile, our system leverages a novel interpolation algorithm to help users insert intermediate frames between the keyframes to smooth the transition. We evaluated the effectiveness and usefulness of the Erato system via a series of evaluations including a Turing test, a controlled user study, a performance validation, and interviews with three expert users. The evaluation results showed that the proposed interpolation technique was able to generate coherent story content and help users create data stories more efficiently.

description: Secondary electron emission (SEE) from solids plays an important role in many areas of science and technology.1 In recent years, there has been renewed interest in the experimental and theoretical studies of SEE. A recent study proposed that the reflectivity of very low energy electrons from solid surface approaches unity in the limit of zero electron energy2,3,4, If this was indeed the case, this effect would have profound implications on the formation of electron clouds in particle accelerators,2-4 plasma measurements with electrostatic Langmuir probes, and operation of Hall plasma thrusters for spacecraft propulsion5,6. It appears that, the proposed high electron reflectivity at low electron energies contradicts to numerous previous experimental studies of the secondary electron emission7. The goal of this note is to discuss possible causes of these contradictions.

Kinetic Theory and Memory Effects of Homogeneous Inelastic Granular Gases under Nonlinear Drag

description: We study a dilute granular gas immersed in a thermal bath made of smaller particles with masses not much smaller than the granular ones in this work. Granular particles are assumed to have inelastic and hard interactions, losing energy in collisions as accounted by a constant coefficient of normal restitution. The interaction with the thermal bath is modeled by a nonlinear drag force plus a white-noise stochastic force. The kinetic theory for this system is described by an Enskog--Fokker--Planck equation for the one-particle velocity distribution function. To get explicit results of the temperature aging and steady states, Maxwellian and first Sonine approximations are developed. The latter takes into account the coupling of the excess kurtosis with the temperature. Theoretical predictions are compared with direct simulation Monte Carlo and event-driven molecular dynamics simulations. While good results for the granular temperature are obtained from the Maxwellian approximation, a much better agreement, especially as inelasticity and drag nonlinearity increase, is found when using the first Sonine approximation. The latter approximation is, additionally, crucial to account for memory effects such as Mpemba and Kovacs-like ones.

description: We have studied the quasi-free dissociation of quarkonia through a complex potential which is obtained by correcting both the perturbative and nonperturbative terms of the $Q \bar Q$ potential at T=0 through the dielectric function in real-time formalism. The presence of confining nonperturbative term even above the transition temperature makes the real-part of the potential more stronger and thus makes the quarkonia more bound and also enhances the (magnitude) imaginary-part which, in turn contributes more to the thermal width, compared to the medium-contribution of the perturbative term alone. These cumulative observations result the quarkonia to dissociate at higher temperatures. Finally we extend our calculation to a medium, exhibiting local momentum anisotropy, by calculating the leading anisotropic corrections to the propagators in Keldysh representation. The presence of anisotropy makes the real-part of the potential stronger but the imaginary-part is weakened slightly. However, since the medium corrections to the imaginary-part is a small perturbation to the vacuum part, overall the anisotropy makes the dissociation temperatures higher, compared to isotropic medium.

description: This paper reviews the dynamics of an isotropic and homogeneous cosmological scalar field. A general approach to the solution of the Einstein-Klein-Gordon equations is developed, which does not require slow-roll or other approximations. General conclusions about the qualitative behaviour of the solutions can be drawn, and examples of explicit solutions for some interesting cases are given. It is also shown how to find scalar potentials giving rise to a predetermined scalar field behaviour and associated evolution of the scale factor.

description: It was recently pointed out that linear quantum fields $\hat ϕ(x)$ can be meaningfully propagated across the big bang (and the big crunch) singularities of spatially flat Friedmann, Lemaître, Robertson, Walker (FLRW) universes \cite{ADLS2021}. Recall that $\hat ϕ(x)$, as well as renormalized observables $\langle\hat ϕ(x)^2 \rangle_{ren}$ and $\langle \hat T_{ab}(x)\rangle_{ren}$, are distribution-valued already in Minkowskian quantum field theories. It was shown that they can be extended as well-defined distributions even when these space-times are enlarged to include the big-bang (or the big crunch). We generalize these results to spatially closed and open FLRW models, showing that this `tameness' of cosmological singularities is not an artifact of the technical simplifications due to spatial flatness. Our analysis also provides explicit expressions of $\langle\hat ϕ(x) \hat ϕ(x') \rangle_{ren}$, $\langle\hat ϕ(x)^2 \rangle_{ren}$ and $\langle \hat T_{ab}(x)\rangle_{ren}$ in closed and open universes for minimally coupled massless scalar fields and discuss the ambiguities in the definition of $\langle \hat T_{ab}(x)\rangle_{ren}$ at the big-bang. While the technical expressions are more complicated than in the spatially flat case, there is also an unexpected conceptual simplification: the infrared divergence \cite{fp} is now absent because, in effect, the spatial curvature provides a natural cutoff. Finally, we further clarify the sense in which quantum field theory can continue to be well defined even though the extended space-time is not globally hyperbolic because of the singularity, and suggest directions for further work.
