description: We present an overview of galaxy evolution across cosmic time in the Illustris Simulation. Illustris is an N-body/hydrodynamical simulation that evolves 2*1820^3 resolution elements in a (106.5Mpc)^3 box from cosmological initial conditions down to z=0 using the AREPO moving-mesh code. The simulation uses a state-of-the-art set of physical models for galaxy formation that was tuned to reproduce the z=0 stellar mass function and the history of the cosmic star-formation rate density. We find that Illustris successfully reproduces a plethora of observations of galaxy populations at various redshifts, for which no tuning was performed, and provide predictions for future observations. In particular, we discuss (a) the buildup of galactic mass, showing stellar mass functions and the relations between stellar mass and halo mass from z=7 to z=0, (b) galaxy number density profiles around massive central galaxies out to z=4, (c) the gas and total baryon content of both galaxies and their halos for different redshifts, and as a function of mass and radius, and (d) the evolution of galaxy specific star-formation rates up to z=8. In addition, we (i) present a qualitative analysis of galaxy morphologies from z=5 to z=0, for the stellar as well as the gaseous components, and their appearance in HST mock observations, (ii) follow galaxies selected at z=2 to their z=0 descendants, and quantify their growth and merger histories, and (iii) track massive z=0 galaxies to high redshift and study their joint evolution in star-formation activity and compactness. We conclude with a discussion of several disagreements with observations, and lay out possible directions for future research.

description: This research project investigates the Pedagogical Content Knowledge (PCK) of trainee mathematics teachers going through the PGCE programme. I analyzed five interviews from each of five trainees at different times in their training regarding their choices on matters that relate to PCK using grounded theory. This produced a collection of factors that affected their PCK during their training. These factors and their particular effects on the trainees were described in detail through the lens of the communities of practice theory. This study provides a view of the experience of learning to become a mathematics teacher through the PGCE programme and suggests that is is extremely varied. Most of the factors identified were not consistent for all the trainees, and those that were shared often had different effects. The similarities and differences of these factors are presented in this study, with some implications and ideas for further study.
What I cannot do without you. Towards a truly embedded and embodied account of the socially extended mind

description: Through a discussion of the socially extended mind, this paper advances the “not possible without principle” as an alternative to the social parity principle. By charging the social parity principle with reductionism about the social dimension of socially extended processes, the paper offers a new argumentative strategy for the socially extended mind that stresses its existential significance. The “not possible without principle” shows that not only is something more achieved through socially located processes of knowledge building, but also that, and more importantly, what is achieved is something that would not have been possible without social interaction. The social parity principle states that the result of an activity achieved via social interaction should be assumed functionally equivalent to a solitary investigation and is characterized by multiple realisability. Contrary to the social parity principle, the “not possible without principle” holds that the result would not have been achieved without the social interaction between (at least) two agents with specific existential needs. The socially extended mind never happens in a void. This means that the "not possible without" principle should be located in real-life, affectively charged, embodied experiences of skilful interactions between agents. This fundamental conceptual change via reference to the “existential necessity” that regulates socially extended processes is necessary in order to effectively lead the socially extended mind to a truly embedded and embodied account.

description: The vibrational properties of ferrimagnetic $\mathrm{Mn_3Si_{2}Te_6}$ single crystals are investigated using Raman spectroscopy and density functional theory calculations. Eighteen Raman-active modes are identified, fourteen of which are assigned according to with the trigonal symmetry. Four additional peaks, obeying the $A_{1g}$ selection rules, are attributed to the overtones. The unconventional temperature evolution of the $A_{1g}^5$ mode self-energy suggests a competition between different short-range magnetic correlations that significantly impact the spin-phonon interaction in $\mathrm{Mn_3Si_{2}Te_6}$. The research provides a comprehensive insight to the lattice properties, studies their temperature dependence and shows the arguments for existence of competing short-range magnetic phases in $\mathrm{Mn_3Si_{2}Te_6}$.

description: The Extended Smooth Pathway Model (ESPM) presented here provides a framework for allocating a global CO2 budget to countries and deriving national emission paths. Exemplary emission targets are shown for the EU. The derivation of Paris-compatible emission paths, however, requires science-based political decisions about the global budget, its distribution, the potential for future net negative emissions and the course of national emission paths.

description: The lepton sector of the Standard Model is at present haunted by several intriguing anomalies, including an emerging pattern of deviations in $b \to s \ell \ell$ processes, with hints of lepton flavor universality violation, and a discrepancy in the muon anomalous magnetic moment. More importantly, it cannot explain neutrino oscillation data, which necessarily imply the existence of non-zero neutrino masses and lepton mixings. We propose a model that accommodates all the aforecited anomalies, induces neutrino masses and provides a testable dark matter candidate. This is achieved by introducing a dark sector contributing to the observables of interest at the 1-loop level. Our setup provides a very economical explanation to all these open questions in particle physics and is compatible with the current experimental constraints.

Swimming path statistics of an active Brownian particle with time-dependent self-propulsion

description: Typically, in the description of active Brownian particles, a constant effective propulsion force is assumed, which is then subjected to fluctuations in orientation and translation leading to a persistent random walk with an enlarged long-time diffusion coefficient. Here, we generalize previous results for the swimming path statistics to a time-dependent and thus in many situations more realistic propulsion which is a prescribed input. We analytically calculate both the noise-free and the noise-averaged trajectories for time-periodic propulsion under the action of an additional torque. In the deterministic case, such an oscillatory microswimmer moves on closed paths that can be highly more complicated than the commonly observed straight lines and circles. When exposed to random fluctuations, the mean trajectories turn out to be self-similar curves which bear the characteristics of their noise-free counterparts. Furthermore, we consider a propulsion force which scales in time $t$ as $\propto \! t^α$ (with $α=0,1,2,\ldots$) and analyze the resulting superdiffusive behaviour. Our predictions are verifiable for diffusiophoretic artificial microswimmers with prescribed propulsion protocols.

description: Beyond providing accurate movements, achieving smooth motion trajectories is a long-standing goal of robotics control theory for arms aiming to replicate natural human movements. Drawing inspiration from biological agents, whose reaching control networks effortlessly give rise to smooth and precise movements, can simplify these control objectives for robot arms. Neuromorphic processors, which mimic the brain's computational principles, are an ideal platform to approximate the accuracy and smoothness of biological controllers while maximizing their energy efficiency and robustness. However, the incompatibility of conventional control methods with neuromorphic hardware limits the computational efficiency and explainability of their existing adaptations. In contrast, the neuronal subnetworks underlying smooth and accurate reaching movements are effective, minimal, and inherently compatible with neuromorphic hardware. In this work, we emulate these networks with a biologically realistic spiking neural network for motor control on neuromorphic hardware. The proposed controller incorporates experimentally-identified short-term synaptic plasticity and specialized neurons that regulate sensory feedback gain to provide smooth and accurate joint control across a wide motion range. Concurrently, it preserves the minimal complexity of its biological counterpart and is directly deployable on Intel's neuromorphic processor. Using the joint controller as a building block and inspired by joint coordination in human arms, we scaled up this approach to control real-world robot arms. The trajectories and smooth, bell-shaped velocity profiles of the resulting motions resembled those of humans, verifying the biological relevance of the controller. Notably, the method achieved state-of-the-art control performance while decreasing the motion jerk by 19% to improve motion smoothness.

description: Competing definitions of justice in Plato's Republic and Aristotle's Politics indicate the existence of two distinct economic systems with different priorities. The three-class society of the Platonic economy (guardians, auxiliaries, producers) gives rise to guardians who by virtue are expected to enforce output targets on producers directly or through auxiliaries. The three-class society of the Aristotelian economy (rich, middle, poor) facilitates the emergence of different ruling coalitions and compensates the efficiency losses of central planning with political gains derived from representative governance. In the Aristotelian economy, the middle class is better off than in the Platonic economy (auxiliaries), because a just society (polity) is achieved under its coalition with the rich. I argue that the equilibrium solutions of the Platonic and Aristotelian economic systems provide analytical insights on the origins of capitalist and socialist political economies.

description: We derive mass-independent equations and inequalities for Kerr-Newman-anti-de Sitter black holes. In particular, we obtain an equation that relates electric charge, angular momentum and the areas of the event and Cauchy horizons. An area-angular momentum-charge inequality is derived from this formula, which becomes an equality in the degenerate limit. The same equation is shown to hold for arbitrary degenerate black holes, which might, for example, be surrounded by matter.

description: To explore the non-Euclidean generalization of higher-order topological phenomena, we construct a higher-order topological insulator model in hyperbolic lattices by breaking the time-reversal symmetry (TRS) of quantum spin Hall insulators. We investigate three kinds of hyperbolic lattices, i.e., hyperbolic $\{4,5\}$, $\{8,3\}$ and $\{12,3\}$ lattices, respectively. The non-Euclidean higher-order topological behavior is characterized by zero-energy effective corner states appearing in hyperbolic lattices. By adjusting the variation period of the TRS breaking term, we obtain 4, 8 and 12 zero-energy effective corner states in these three different hyperbolic lattices, respectively. It is found that the number of zero-energy effective corner states of a hyperbolic lattice depends on the variation period of the TRS breaking term. The real-space quadrupole moment is employed to characterize the higher-order topology of the hyperbolic lattice with four zero-energy effective corner states. Via symmetry analysis, it is confirmed that the hyperbolic zero-energy effective corner states are protected by the particle-hole symmetry $P$, the effective chiral symmetry $Sm_{z}$, and combined symmetries $C_{p}T$ and $C_{p}m_{z}$. The hyperbolic zero-energy effective corner states remain stable unless these four symmetries are broken simultaneously. The topological nature of hyperbolic zero-energy effective corner states is further confirmed by checking the robustness of the zero-energy modes in the hyperbolic lattices in the presence of disorder. Our paper provides a route for research on hyperbolic higher-order topological insulators in non-Euclidean geometric systems.

description: This article describes the usage of partial interrogatives without wh such as And you went…? in French and Spanish, and analyses the variation between such in-situ-Ø and in-situ-wh-interrogatives such as And you went where? On the basis of an analysis of in-situ-Ø-interrogatives in a corpus of spoken French and Spanish, these interrogatives are described as a particularly efficient means of realizing an information request. Due to the fact that their use is bound to contexts in which the information request is highly expected by the hearer, they can be produced using a minimal syntactic format and simultaneously ensure that the addressee produces the desired response. In comparison, the use of in-situ-wh is less context-sensitive. The analysis also investigates the possibility of differences between French and Spanish as regards the productivity of these interrogatives. An acceptability study of these interrogatives finds no significant difference in terms of the productivity and acceptability of in-situ-Ø in French and Spanish, whereas in-situ-wh reaches a higher acceptability in French than in Spanish. I interpret these results as evidence for a description of in-situ-Ø as an ad-hoc interactional resource whose use does not depend on conventionalization processes, whereas information-requesting in-situ-wh has become conventional in French.

description: Direct observations of low-mass, low-metallicity galaxies at $z\gtrsim4$ provide an indispensable opportunity for detailed inspection of the ionization radiation, gas flow, and metal enrichment in sources similar to those that reionized the Universe. Combining the James Webb Space Telescope (JWST), VLT/MUSE, and ALMA, we present detailed observations of a strongly lensed, low-mass ($\approx 10^{7.6}$ ${\rm M}_\odot$) galaxy at $z=3.98$ (also see Vanzella et al. 2022). We identify strong narrow nebular emission, including CIV $λ\lambda1548,1550$, HeII $\lambda1640$, OIII] $λ\lambda1661,1666$, [NeIII] $\lambda3868$, [OII] $\lambda3727$, and Balmer series of Hydrogen from this galaxy, indicating a metal-poor HII region ($\lesssim 0.12\ {\rm Z}_\odot$) powered by massive stars. Further, we detect a metal-enriched damped Ly$α$ system (DLA) associated with the galaxy with the HI column density of $N_{\rm{HI}}\approx 10^{21.8}$ cm$^{-2}$. The metallicity of the associated DLA may reach the super solar metallicity (${\gtrsim Z}_\odot$). Moreover, thanks to JWST and gravitational lensing, we present the resolved UV slope ($β$) map at the spatial resolution of $\approx 100$ pc at $z=4$, with steep UV slopes reaching $β\approx -2.5$ around three star-forming clumps. Combining with low-redshift analogs, our observations suggest that low-mass, low-metallicity galaxies, which dominate reionization, could be surrounded by a high covering fraction of the metal-enriched, neutral-gaseous clouds. This implies that the metal enrichment of low-mass galaxies is highly efficient, and further support that in low-mass galaxies, only a small fraction of ionizing radiation can escape through the interstellar or circumgalactic channels with low column-density neutral gas.

description: Top taggers are established analysis tools to reconstruct boosted hadronically decaying top quarks for example in searches for heavy resonances. We first present a dedicated study of signal efficiency versus background rejection, allowing for an improved choice of working points. Next, we determine to what degree our mass drop selection can be improved by systematically including angular correlations between the decay subjets. Finally, we extend the reach of the top tagger to transverse momenta below the top mass. This momentum range will be crucial in searches for the associated production of a Higgs boson with top quarks.

description: A precise structural determination of supramolecular architectures is a non-trivial challenge. This daunting task can be made even more difficult when interlocked species are to be analysed having macrocycles covalently equipped with a thread as repeating units, such as molecular lassos and daisy chains. When such functionalized macrocycles are included as scaffolds, different products having analogous NMR spectra as well as dynamic libraries can be obtained. Furthermore, if control over the motion of the parts relative to each other is to be achieved, a full understanding of the machinery's operation mechanism requires detailed insight into the structures involved. This understanding also helps designing improved synthetic molecular machines. Diffusion-ordered NMR spectroscopy and ion-mobility MS techniques are ideal tools to study such compounds in depth. This review covers recent examples on the use of the above-mentioned techniques to characterize these interlocked architectures.

description: We report the design and implementation of a high-performance superconducting quantum interference proximity transistor (SQUIPT) based on aluminum-copper (Al-Cu) technology. With the adoption of a thin and short copper nanowire we demostrate full phase-driven modulation of the proximity-induced minigap in the normal metal density of states. Under optimal bias we record unprecedently high flux-to-voltage (up to 3 mV/$Φ_0$) and flux-to-current (exceeding 100 nA/$Φ_0$) transfer function values at sub-Kelvin temperatures, where $Φ_0$ is the flux quantum. The best magnetic flux resolution (as low as 500 n$Φ_0/\sqrt{Hz}$ at 240 mK, being limited by the room temperature pre-amplification stage) is reached under fixed current bias. These figures of merit combined with ultra-low power dissipation and micrometer-size dimensions make this mesoscopic interferometer attractive for low-temperature applications such as the investigation of the magnetization of small spin populations.

We calculate the waiting time distribution for a quantum point contact and find a cross-over from Wigner-Dyson statistics at full transmission to Poisson statistics close to pinch-off as predicted by scattering theory. In addition, we consider several quantum dot structures for which we can associate oscillations in the waiting time distributions to internal energy scales of the scatterers. A detailed comparison with scattering theory and generalized master equations is provided. We focus on mesoscopic conductors, but our tight-binding models may also be realized in cold atomic gases.

description: We revisit the quark-mass density-dependent model -- a phenomenological equation of state for deconfined quark matter in the high-density low-temperature regime -- and show that thermodynamic inconsistencies that have plagued the model for decades, can be solved if the model is formulated in the canonical ensemble instead of the grand canonical one. Within the new formulation, the minimum of the energy per baryon occurs at zero pressure, and the Euler's relation is verified. Adopting a typical mass-formula, we first analyze in detail a simple model with one particle species. We show that a ``bag'' term that produces quark confinement naturally appears in the pressure (and not in the energy density) due to density dependence of the quark masses. Additionally, the chemical potential gains a new term as in other models with quark repulsive interactions. Then, we extend the formalism to the astrophysically realistic case of charge-neutral three-flavor quark matter in equilibrium under weak interactions, focusing on two different mass formulae: a flavor dependent and a flavor blind one. For these two models, we derive the equation of state and analyze its behavior for several parameter choices. We systematically analyze the parameter space and identify the regions corresponding to self-bound 2-flavor and 3-flavor quark matter, hybrid matter and causal behavior.

description: This article empirically investigates possible politeness effects of different syntactic, morphosyntactic, and lexical mitigating strategies in German requests. In addition to the explicitness of the requestive utterance, internal and external modifiers as well as vocatives are considered. Based on the assumption that the weight of imposition has an influence on linguistic politeness, experimentally elicited production data for two requestive situations with a differing degree of imposition are compared regarding their formal properties. The data come from an online survey in which 578 native speakers of German (from Germany, Switzerland, and Austria) took part. The participants produced 1,006 requests. These were coded for several mitigating strategies and analyzed with a multifactorial analysis in order to identify the devices that are used in the high-imposition context and thus can be interpreted as conveying extra politeness. An important finding is that increased politeness is realized via devices beyond the head act strategy, namely morpho-syntactic and lexical tentativeness markers as well as multiple external modifiers.

description: We analytically and numerically compute three equilibrium Fermi-liquid coefficients of the fully screened $N$-channel Kondo model, namely $c_B$, $c_T$ and $c_\varepsilon$, characterizing the magnetic field and temperature dependence of the resisitivity, and the curvature of the equilibrium Kondo resonance, respectively. We present a compact, unified derivation of the $N$-dependence of these coefficients, combining elements from various previous treatments of this model. We numerically compute these coefficients using the numerical renormalization group, with non-Abelian symmetries implemented explicitly, finding agreement with Fermi-liquid predictions on the order of 5% or better.

description: Trust is highlighted as central to effective disease management. During the COVID-19 pandemic, Denmark seemed to embody this understanding. Characterizing the Danish response were high levels of public compliance with government regulations and restrictions coupled with high trust in the government and other members of society. In this article, we first revisit prior claims about the importance of trust in securing compliant citizen behaviour based on a weekly time-use survey that we conducted during the first weeks of the COVID-19 pandemic (2 April–18 May 2020). Analysis of activity episodes, rather than merely self-reported compliance, both reconfirms the importance of institutional trust and nuances prior suggestions of detrimental effects of trust in other citizens. These survey-based results are further augmented through thematic analysis of 21 in-depth interviews with respondents sampled from the survey participants. The qualitative analysis reveals two themes, the first focusing on trust in others in Danish society and the second on the history of trust in Denmark. Both themes are based on narratives layered in cultural, institutional and inter-personal levels and further underline that institutional and social trust are complementary and not countervailing. We conclude by discussing how our analysis suggests pathways towards an increased social contract between governments, institutions and individuals that might be of use during future global emergencies and to the overall functioning of democracies.
Determining the stellar masses of submillimetre galaxies: the critical importance of star formation histories

description: Submillimetre (submm) galaxies are among the most rapidly star-forming and most massive high-redshift galaxies; thus, their properties provide important constraints on galaxy evolution models. However, there is still a debate about their stellar masses and their nature in the context of the general galaxy population. To test the reliability of their stellar mass determinations, we used a sample of simulated submm galaxies for which we derived stellar masses via spectral energy distribution (SED) modelling (with Grasil, Magphys, Hyperz and LePhare) adopting various star formation histories (SFHs). We found that the assumption of SFHs with two independent components leads to the most accurate stellar masses. Exponentially declining SFHs (tau) lead to lower masses (albeit still consistent with the true values), while the assumption of single-burst SFHs results in a significant mass underestimation. Thus, we conclude that studies based on the higher masses inferred from fitting the SEDs of real submm galaxies with double SFHs are most likely to be correct, implying that submm galaxies lie on the high-mass end of the main sequence of star-forming galaxies. This conclusion appears robust to assumptions of whether or not submm galaxies are driven by major mergers, since the suite of simulated galaxies modelled here contains examples of both merging and isolated galaxies. We identified discrepancies between the true and inferred stellar ages (rather than the dust attenuation) as the primary determinant of the success/failure of the mass recovery. Regardless of the choice of SFH, the SED-derived stellar masses exhibit a factor of ~2 scatter around the true value; this scatter is an inherent limitation of the SED modelling due to simplified assumptions. Finally, we found that the contribution of active galactic nuclei does not have any significant impact on the derived stellar masses.

description: We propose a non-Hermitian generalization of the correspondence between the spectral flow and the topological charges of band crossing points (Berry-Chern monopoles). A class of non-Hermitian Hamiltonians that display a complex-valued spectral flow is built by deforming an Hermitian model while preserving its analytical index. We relate those spectral flows to a generalized Chern number that we show to be equal to that of the Hermitian case, provided a line gap exists. We demonstrate the homotopic invariance of both the non-Hermitian Chern number and the spectral flow index, making explicit their topological nature. In the absence of a line gap, our system still displays a spectral flow whose topology can be captured by exploiting an emergent pseudo-Hermitian symmetry.

Interaction between a Rising Bubble and a Stationary Droplet Immersed in a Liquid Pool using Ternary Conservative Phase-Field Lattice Boltzmann Method

description: When a stationary bubble and a stationary droplet immersed in a liquid pool are brought in contact with each other, they form a bubble-droplet aggregate. Its equilibrium morphology and stability largely depend on the combination of different components' surface tensions, known as spreading factor. In this study, we look at the interaction between a rising bubble and a stationary droplet to better understand the dynamics of coalescence and rising as well as morphological changes for the bubble-droplet aggregate. A systematic study is conducted on the interaction processes with various bubble sizes and spreading factors. The current simulation framework consists of the ternary conservative phase-field Lattice Boltzmann method (LBM) for interface tracking and the velocity-pressure LBM for hydrodynamics, which is validated for the benchmark cases such as liquid lens and parasitic currents around a static droplet with several popular surface tension formulations. We further test our LBM for the morphology changes of two droplets initially in contact with various spreading factors and depict the final morphologies in a phase diagram. The separated, partially engulfed and completely engulfed morphologies can be replicated by systematically altering the sign of the spreading factors. The rising bubble and stationary droplet interaction is simulated based on the final morphologies obtained under stationary conditions by imposing an imaginary buoyancy force on the rising bubble. The results indicate that the bubble-droplet aggregate with double emulsion morphology can minimize the distotion of the bubble-droplet aggregate and achieve a greater terminal velocity than the aggregate with partially engulfed morphology.
