description: Charge density-wave order has been observed in cuprate superconductors whose crystal structure breaks the square symmetry of the CuO2 planes, such as orthorhombic YBa2Cu3Oy (YBCO), but not so far in cuprates that preserve that symmetry, such as tetragonal HgBa2CuO4+d (Hg1201). We have measured the Hall (R_H), Seebeck (S), and Nernst coefficients of underdoped Hg1201 in magnetic fields large enough to suppress superconductivity. The high-field R_H(T) and S(T) are found to drop with decreasing temperature and become negative, as also observed in YBCO at comparable doping. In YBCO, the negative R_H and S are signatures of a small electron pocket caused by Fermi-surface reconstruction, attributed to charge density-wave modulations observed in the same range of doping and temperature. We deduce that a similar Fermi-surface reconstruction takes place in Hg1201, evidence that density-wave order exists in this material. A striking similarity is also found in the normal-state Nernst coefficient, further supporting this interpretation. Given the model nature of Hg1201, Fermi-surface reconstruction appears to be common to all hole-doped cuprates, suggesting that density-wave order is a fundamental property of these materials.

description: Using extensive classical and quantum Monte Carlo simulations, we investigate the ground-state phase diagram of the fully frustrated transverse field Ising model on the square lattice. We show that pure columnar order develops in the low-field phase above a surprisingly large length scale, below which an effective U(1) symmetry is present. The same conclusion applies to the Quantum Dimer Model with purely kinetic energy, to which the model reduces in the zero-field limit, as well as to the stacked classical version of the model. By contrast, the 2D classical version of the model is shown to develop plaquette order. Semiclassical arguments show that the transition from plaquette to columnar order is a consequence of quantum fluctuations.

The impact of narratives on policy-making at the national level

Subjects: migration

description: This report examines the way in which narratives on migration circulate in France across communicative and coordinative spheres (Schmidt 2008). It focuses on three events: the relocation of migrants in 2015, the temporary protection triggered for the war in Ukraine in 2022 and the allocation of a port for the Aquarius in 2018. It explores whether narratives are embraced, adapted, ignored, or rejected between the media, Parliament, and administrations. The first result shows that these narratives are generally positive towards migrants because they are detached from two sensitive issues in France: the integration of immigrants and the violence they might commit. A second finding is that, overall, within the communicative sphere, parliamentarians tend to reproduce the media narrative, whereas the media tend to favour the narrative of French and European governments. As well, for the relocation and the temporary protection, the coordinative sphere (consisting of administrative circulars) has a slightly different narrative because, unlike the media and Parliament, it enforces policy solutions and does not propose any. But, for the Aquarius event, the coordinative sphere (corresponding to a presidential speech) embraces the narratives of parliamentarians and the media to counter the arguments attacking the French government. A third result proposes to distinguish between 'lay' and 'technocratic' narratives based on their content and the way in which they use the notion of 'the people'. The fourth result establishes a link between the use of 'lay' or 'technocratic' narratives by the government depending on the context in which it is situated.

Lett. {\bf 98}, 226403 (2007)]. We also show that some of the recent formulations attempting to improve on this theory suffer from some inconsistencies, especially in establishing the mapping between the external potential and the quantities of interest. We offer a general argument about this mapping, showing that it must fulfill certain "dimensionality" requirements.

description: There are two sets of four-by-four matrices introduced by Dirac. The first set consists of fifteen Majorana matrices derivable from his four $γ$ matrices. These fifteen matrices can also serve as the generators of the group $SL(4,r)$. The second set consists of ten generators of the $Sp(4)$ group which Dirac derived from two coupled harmonic oscillators. It is shown possible to extend the symmetry of $Sp(4)$ to that of $SL(4,r)$ if the area of the phase space of one of the oscillators is allowed to become smaller without a lower limit. While there are no restrictions on the size of phase space in classical mechanics, Feynman's rest of the universe makes this $Sp(4)$-to-$SL(4,r)$ transition possible. The ten generators are for the world where quantum mechanics is valid. The remaining five generators belong to the rest of the universe. It is noted that the groups $SL(4,r)$ and $Sp(4)$ are locally isomorphic to the Lorentz groups O(3,3) and O(3,2) respectively. This allows us to interpret Feynman's rest of the universe in terms of space-time symmetry.

Universal and non-universal features of the generalized voter class for ordering dynamics

description: By considering three different spin models belonging to the generalized voter class for ordering dynamics in two dimensions [I. Dornic, \textit{et al.} Phys. Rev. Lett. \textbf{87}, 045701 (2001)], we show that they behave differently from the linear voter model when the initial configuration is an unbalanced mixture up and down spins. In particular we show that for nonlinear voter models the exit probability (probability to end with all spins up when starting with an initial fraction $x$ of them) assumes a nontrivial shape. The change is traced back to the strong nonconservation of the average magnetization during the early stages of dynamics. Also the time needed to reach the final consensus state $T_N(x)$ has an anomalous nonuniversal dependence on $x$.

Two distinct phases in the first 13 seconds of GRB110731A prompt emission

description: In this work, the time-resolved BAT/GBM/LAT joint spectral analysis of GRB110731A during the prompt phase from the GBM trigger and up to 13 seconds later showed that, at the very early phase of prompt emission, the emission mechanism is closest to the standard fireball model. This model over-predicts the thermal photospheric emission and used to contradict observations. Lightcurves at different energy bands revealed two distinguishable phases that may come from different regions. First, we have an early phase, which is not detected by LAT, and is dominated by lower energies, which arises from the photospheric emissions without any emissions involved in dissipation mechanisms and characterized by low Lorentz factor and high radiation efficiency. This is followed by a later phase, having a more complex structure that remarkably follows the same track in all energy bands and is attributed to emissions from internal shocks. This burst is a good candidate to study both thermal and non-thermal emissions, since the two phases can be clearly separated in lightcurve and spectrum. The rapid variation of Lorentz factor and the values of photospheric radii, which are relatively far away from the central engine in Phase 2, are more consistent with the mechanism of collisional heating in baryonic jets. Further information can be obtained by combining more wavelengths with the help of the other detectors.

description: We define a quasar-galaxy mixing diagram using the slopes of their spectral energy distributions (SEDs) from 1μm to 3000Å and from 1μm to 3μm in the rest frame. The mixing diagram can easily distinguish among quasar-dominated, galaxy-dominated and reddening-dominated SED shapes. By studying the position of the 413 XMM selected Type 1 AGN in the wide-field "Cosmic Evolution Survey" (COSMOS) in the mixing diagram, we find that a combination of the Elvis et al. (1994, hereafter E94) quasar SED with various contributions from galaxy emission and some dust reddening is remarkably effective in describing the SED shape from 0.3-3μm for large ranges of redshift, luminosity, black hole mass and Eddington ratio of type 1 AGN. In particular, the location in the mixing diagram of the highest luminosity AGN is very close (within 1σ) to that of the E94 SED. The mixing diagram can also be used to estimate the host galaxy fraction and reddening in quasar. We also show examples of some outliers which might be AGN in different evolutionary stages compared to the majority of AGN in the quasar-host galaxy co-evolution cycle.

description: The forest of Lyman-alpha absorption lines seen in the spectra of distant quasars has become an important probe of the distribution of matter in the Universe. We use large, hydrodynamical simulations from the OWLS project to investigate the effect of feedback from galaxy formation on the probability distribution function and the power spectrum of the Lyman-alpha transmitted flux. While metal-line cooling is unimportant, both galactic outflows from massive galaxies driven by active galactic nuclei and winds from low-mass galaxies driven by supernovae have a substantial impact on the flux statistics. At redshift z=2.25, the effects on the flux statistics are of a similar magnitude as the statistical uncertainties of published data sets. The changes in the flux statistics are not due to differences in the temperature-density relation of the photo-ionised gas. Instead, they are caused by changes in the density distribution and in the fraction of hot, collisionally ionised gas. It may be possible to disentangle astrophysical and cosmological effects by taking advantage of the fact that they induce different redshift dependencies. In particular, the magnitude of the feedback effects appears to decrease rapidly with increasing redshift. Analyses of Lyman-alpha forest data from surveys that are currently in process, such as BOSS/SDSS-III and X-Shooter/VLT, must take galactic winds into account.

description: Für mehr Transparenz im Hinblick auf die Entwicklung und den Einsatz von Künstlicher Intelligenz (KI) sprechen sich alle aus – von der Gerechtigkeitsaktivistin bis zum Tech-CEO – und mit einem KI-Transparenzregister kann ein wichtiger Schritt von Wunsch zu Wirklichkeit gegangen werden. Insbesondere beim Einsatz von KI-Systemen im öffentlichen Sektor ist der Bedarf an Informationen hoch, die Bereitstellung bisher jedoch gering.

Das Projekt reframe[Tech] der Bertelsmann Stiftung hat sich vor diesem Hintergrund in den letzten Monaten mit der Frage beschäftigt, ob und wie ein KI-Transparenzregister für die öffentliche Verwaltung dieses Missverhältnis zwischen Informationsbedarf und -bereitstellung adressieren kann. Die ersten Erfahrungen mit solchen KI-Registern werden bereits seit 2020 in den Städten Helsinki und Amsterdam gewonnen.

In Workshops mit Vertreter:innen aus der öffentlichen Verwaltung und Expert:innen für den verantwortungsvollen Einsatz von KI-Systemen haben wir die wichtigsten Voraussetzungen für die gelingende Einführung eines KI-Transparenzregisters in Deutschland diskutiert. In der vorliegenden Publikation stellt Autorin Vanessa Weeke die Ergebnisse vor und ordnet ein, dass ein solches Register nicht nur ein wichtiges Instrument für mehr Transparenz, sondern auch eine elementare Austauschplattform für die öffentliche Verwaltung sein könnte. Um dies zu erreichen, muss jedoch vor allem ein Flickenteppich an verschiedenen Registern vermieden werden.

Alle Beteiligten waren sich über die Disziplinen hinaus einig, dass das Zeitfenster für die Einführung eines KI-Registers in Deutschland aktuell besonders günstig ist. Wir hoffen, dass diese Publikation zu dem Diskurs einordnend beitragen kann. Wir freuen uns über Resonanz und natürlich jede Form konstruktiver Kritik.
title: RE-IMAGINING ROMANIAN CULTURE FROM AFAR THROUGH STILL LIFE PHOTOGRAPHIC IMAGES OF WOLF MYTHS
Creators: name: Modoi, Alexandru Gelu
Publisher: name: University of Central Lancashire
Year: 2023

description: This study aims to investigate how creative practice can help to find new photographic ways to re-imagine Romanian culture through disciplinary and interdisciplinary photographic methods and identify possible entangled situations. It intends to portray Romanian culture in a new light, through its wolf myths. It questions how can a practice of photographing objects help to re-imagine Romanian culture from afar through the photographic image? This is the main question that led the initial stages of this research and created new questions, including how to photograph the indexical and what is the photo-entanglement. The problem is that through the photographic image, the representations of myths are often distorted, misrepresented, or only partially revealed. From an artist’s personal experience of living in the UK, Romania is often portrayed in terms of immigration and Transylvanian stories of Dracula, including experiences of being included in discussions about the prejudiced images of Romanians. It can be argued that stories can be shared through photography, including those of Romanian wolf myths and folklore. This research focuses on Romanian culture through its wolf myths and looks at new photographic ways of sharing and transporting the significance of culture within the entanglement of material objects and visual culture while working with photographs of still life objects and the banal and still life artefacts and their significance. Jung suggests that collecting stories from the conscious and unconscious realities of the participants could create a common story, and in addition I am guided by Barthes’ third meaning in an analogy to Einstein’s entanglement. The original contribution to knowledge of this research is the artist’s own creative still life photographic practice, including self-reflections on the creative challenges, in response to an ethnographic analysis of the data collected from Romania and the UK. By employing disciplinary and interdisciplinary creative methods of photographing still life objects, this research follows the artist’s creative process of producing a body of work that will articulate the findings, including a portfolio of photographs, an autoethnographic approach and a public exhibition. Potentially, this research will provide a new insight into the practice of photographing still life objects. It introduces the photo-entanglement concept to the field of still life photography to emphasise the importance of the indexical meaning within this field. A new systematic process of enquiry has been developed that allowed for new ways to explore how and where potential photographic misrepresentations can appear, ultimately providing solutions.

description: We treat a turbulent velocity field as a message in the same way as a book or a picture. All messages can be described by their entropy per symbol $h$, defined as in Shannon's theory of communication. In a turbulent flow, as the Reynolds number $Re$ increases, more correlated degrees of freedom are excited and participate in the turbulent cascade. Experiments in a turbulent soap film suggest that the spatial entropy density $h$ is a decreasing function of $Re$, namely $h \propto -\log Re$ + const. In the logistic map, also analyzed here, increasing the control parameter $r$ increases $h$. A modified logistic map with additional coupling to past iterations suggests the significance of correlations.

description: We have investigated the dynamics of quantum discord and entanglement for two qubits subject to independent global transverse and/or longitudinal memoryless noisy classical fields. Global transverse and/or longitudinal random fields are found to drive the system to maximally discordant mixed separable steady states for suitable initial conditions. Moreover, two independent noises in the system are found to enhance both the steady state randomness and quantum discord in the absence of entanglement for some initial states.

description: We present results of extensive theoretical studies concerning stability, morphology, and band structure of single wall carbon nanotubes (CNTs) covalently functionalized by -CHn(for n=2,3,4),-NHn(for n=1,2,3,4),-COOH and -OH groups. Our studies are based on ab initio calculations in the framework of the density functional theory. We determine the dependence of the binding energies on the concentration of the adsorbed molecules, critical densities of adsorbed molecules, global and local changes in the morphology, and electronic structure paying particular attention to the functionalization induced changes of the band gaps. These studies reveal physical mechanisms that determine stability and electronic structure of those systems and also provide valuable theoretical predictions relevant for application. Functionalization of CNTs causes generally their elongation and locally sp2 -> sp3 rehybridization in the neighborhood of chemisorbed groups. For adsorbants making particularly strong covalent bonds with the CNTs(-CH2), we observe formation of the 5/7 defects. In CNTs functionalized with -CH2,-NH4, and -OH, we determine critical density of molecules that could be covalently bound to CNTs. Functionalization of CNTs can be utilized for band gap engineering and also lead to changes in their metallic/semiconductor character. In semiconducting CNTs, adsorbants such as -CH3,-NH2,-OH and -COOH, introduce 'impurity' bands in the band gap of pristine CNTs. In the case of -CH3,-NH2, the induced band gaps are typically smaller than in the pure CNT and depend strongly on the concentration of adsorbants. However, functionalization of semiconducting CNTs with -OH leads to the metallization of CNTs. On the other hand, the functionalization of semi-metallic (9,0)CNT with -CH2 causes the increase of the band gap and induces semi-metal to semiconductor transition.

description: For over a decade, the hypercomputation movement has produced computational models that in theory solve the algorithmically unsolvable, but they are not physically realizable according to currently accepted physical theories. While opponents to the hypercomputation movement provide arguments against the physical realizability of specific models in order to demonstrate this, these arguments lack the generality to be a satisfactory justification against the construction of \emph{any} information-processing machine that computes beyond the universal Turing machine. To this end, I present a more mathematically concrete challenge to hypercomputability, and will show that one is immediately led into physical impossibilities, thereby demonstrating the infeasibility of hypercomputers more generally. This gives impetus to propose and justify a more plausible starting point for an extension to the classical paradigm that is physically possible, at least in principle. Instead of attempting to rely on infinities such as idealized limits of infinite time or numerical precision, or some other physically unattainable source, one should focus on extending the classical paradigm to better encapsulate modern computational problems that are not well-expressed/modeled by the closed-system paradigm of the Turing machine. I present the first steps toward this goal by considering contemporary computational problems dealing with intractability and issues surrounding cyber-physical systems, and argue that a reasonable extension to the classical paradigm should focus on these issues in order to be practically viable.

description: Spatially embedded networks are shaped by a combination of purely topological (space-independent) and space-dependent formation rules. While it is quite easy to artificially generate networks where the relative importance of these two factors can be varied arbitrarily, it is much more difficult to disentangle these two architectural effects in real networks. Here we propose a solution to the problem by introducing global and local measures of spatial effects that, through a comparison with adequate null models, effectively filter out the spurious contribution of non-spatial constraints. Our filtering allows us to consistently compare different embedded networks or different historical snapshots of the same network. As a challenging application we analyse the World Trade Web, whose topology is expected to depend on geographic distances but is also strongly determined by non-spatial constraints (degree sequence or GDP). Remarkably, we are able to detect weak but significant spatial effects both locally and globally in the network, showing that our method succeeds in retrieving spatial information even when non-spatial factors dominate. We finally relate our results to the economic literature on gravity models and trade globalization.

description: We investigate physical properties of an Anderson impurity embedded in the bulk of a topological insulator. The slave-boson mean-field approximation is used to account for the strong electron correlation at the impurity. Different from the results of a quantum impurity on the surface of a topological insulator, we find for the band-inverted case, a Kondo resonant peak and in-gap bound states can be produced simultaneously. However, only one type of them appears for the normal case. It is shown that the mixed-valence regime is much broader in the band-inverted case, while it shrinks to a very narrow regime in the normal case. Furthermore, a self-screening of the Kondo effect may appear when the interaction between the bound-state spin and impurity spin is taken into account.

description: We numerically solve the Liouville equation for the Tavis Cummings model of multiple spins coupled to a lossless single mode cavity, starting from an initial condition with small numbers of fully polarized spins tipped by a specified angle, and the cavity in its ground Fock state. Time evolution of the magnetizations and cavity states, following small to medium nutation by a classical field, yields a microscopic quantum mechanical picture of radiation damping in magnetic resonance, and the formation of the free induction signal, that is, the transfer of Zeeman energy, via spin coherence, to cavity coherence. Although the motion of the Bloch vector is nonclassical, our quantum description is related to the macroscopic picture of NMR reception, by showing the close relationship between the usual radiation damping constant, and the quantum mechanical Rabi nutation frequency (as enhanced by cavity coupling and stimulated emission.) That is, each is the product, of a nutation rate per oscillator current, and a current. Although the current in the damping constant is explicitly limited by cavity losses, which do not enter the formula for the Rabi frequency, we nonetheless show (in an appendix) how these losses can be introduced into our problem by means of a master equation. Numerical solution of the classical Bloch-Kirchhoff equations reinforces the conclusion that the strength of the free induction

description: Expectations for the magnitude of Higgs boson signals in standard Higgs search channels at the LHC relative to Standard Model (SM) expectations are investigated within the framework of various types of CP and flavor conserving two Higgs doublet models (2HDMs). Signals of the SM-like Higgs boson in different classes of 2HDM may be parameterized in terms of particular two-dimensional sub-spaces of the general four-dimensional space of Higgs couplings to the massive vector bosons, top quark, bottom quark, and tau lepton. We find fairly strong correlations among the inclusive di-photon channel and the exclusive di-photon and di-tau channels from vector boson fusion or associated production. Order one deviations from SM expectations in some of these channels could provide discriminating power among various types of 2HDMs. The ratio of exclusive di-photon to di-tau channels is particularly sensitive to deviations from SM expectations. We also emphasize that deviations from SM expectations in standard Higgs search channels may imply observable signals of non-SM-like Higgs bosons in some of these same channels, in particular in di-photon and di-vector boson channels. The results cataloged here provide a roadmap for interpreting standard Higgs search channels in the context of 2HDMs.

description: Sustainable food system innovations are urgently needed to feed a growing human population while staying within planetary boundaries. Farmed edible insects have received considerable scientific and public attention due to their potential to improve food system circularity by upcycling nutrients from organic residual streams to nutritious food. Earthworms, as non-insect invertebrates, have remained largely unrecognized in the future foods debate. However, they are already widely farmed at industrial scale for their capacity to recycle organic wastes and improve soil fertility. We conducted a systematic literature review to provide a quantitative basis on earthworm nutritional composition, thereby positioning earthworms in the future foods debate. Here we show, based on evidence from 142 scientific studies, that farmed earthworms are a potentially interesting food source. They have an attractive nutrient composition compared to the main farmed edible insect species, being especially rich in protein, low in fat and containing a favourable profile of essential amino acids. The content of important fatty acids, minerals and vitamins in earthworm biomass is higher or lower than in edible insects, depending on the feed material. Crude protein and fat contents are higher in farmed versus wild earthworms, indicating that farming conditions provide a lever for further improving the nutritional composition of earthworm biomass. Whether earthworm species or feed materials affect earthworm nutritional composition could not be finally clarified based on the available data. We conclude that earthworms have high potential as a future food from a nutritional perspective, mainly as an alternative source of protein. The integration of earthworm farming in future food systems can be expected to improve sustainability and circularity, potentially giving earthworms an advantage over edible insects.

description: Direct detection experiments, which are designed to detect the scattering of dark matter off nuclei in detectors, are a critical component in the search for the Universe's missing matter. The count rate in these experiments should experience an annual modulation due to the relative motion of the Earth around the Sun. This modulation, not present for most known background sources, is critical for solidifying the origin of a potential signal as dark matter. In this article, we review the physics of annual modulation, discussing the practical formulae needed to interpret a modulating signal. We focus on how the modulation spectrum changes depending on the particle and astrophysics models for the dark matter. For standard assumptions, the count rate has a cosine dependence with time, with a maximum in June and a minimum in December. Well-motivated generalizations of these models, however, can affect both the phase and amplitude of the modulation. We show how a measurement of an annually modulating signal could teach us about the presence of substructure in the Galactic halo or about the interactions between dark and baryonic matter. Although primarily a theoretical review, we briefly discuss the current experimental situation for annual modulation and future experimental directions.

Masters of sex: Evidence for the dynamic human ability to judge another's sex from ambiguous or unfamiliar signals
Creators: name: Gaetano, Justin Michael
Publisher: name: Journal of Dynamic Decision Making
Year: 2019

description: Humans make decisions about social information efficiently, despite – or perhaps because of – the sheer scale of data available. Of these various signals, sex cues are vitally important, yet understanding whether participants perceive them as static or dynamic is unknown. The present study addressed the related question of how expertise impinges on sex judgements. Participants were asked to target female and male exemplars from a set of own- or other-race hand images. Data show: (1) that the own-race sex categorisation advantage observed previously using face stimuli can occur in relation to hands, and (2) sensitivity of Asian participants, but not Caucasian participants, is dynamic relative to how many fe/males there are in a set. Implications of these findings are discussed as further evidence that there exists a pan-stimulus sex processor, and as fresh evidence that human sex perception can change probabilistically.
