description: Water photodissociation in the 114 - 144 nm UV range forms excited OH which emits at mid-infrared wavelengths via highly excited rotational lines. These lines have only been detected with Spitzer in several proto-planetary disks and shocks. Previous studies have shown they are a unique diagnostic for water photodissociation. Thanks to its high sensitivity and angular resolution, the James Webb Space Telescope (JWST) could be able to detect them in other environments such as interstellar Photo-Dissociation Regions (PDRs). In order to predict the emerging spectrum of OH, we use the Meudon PDR Code to compute the thermal and chemical structure of PDRs. The influence of thermal pressure ($P_{\rm th}/k$ = $n_{\rm H} T_{\rm K}$) and UV field strength on the integrated intensities, as well as their detectability with the JWST are studied in details. OH mid-IR emission is predicted to originate very close to the H$^0$/H$_2$ transition and is directly proportional to the column density of water photodissociated in that layer. Because neutral gas-phase formation of water requires relatively high temperatures ($T_{\rm K} \gtrsim 300~$K), the resulting OH mid-IR lines are primarily correlated with the temperature at this position, and are therefore brighter in regions with high pressure. This implies that these lines are predicted to be only detectable in strongly irradiated PDRs ($G_0^{\rm incident}$ $>$ 10$^3$) with high thermal pressure ($P_{\rm th}/k$ $\gtrsim$ 5$\times$10$^7$ K cm$^{-3}$). In the latter case, OH mid-IR lines are less dependent on the strength of the incident UV field. The detection in PDRs like the Orion bar, which should be possible, is also investigated. To conclude, OH mid-IR lines observable by JWST are a promising diagnostics for dense and strongly irradiated PDRs.

description: We derive a new soft theorem that corresponds to the spontaneous breaking of Lorentz boosts. This is motivated by the dynamics of inflation in the sub-horizon (flat-space) limit, where spacetime becomes flat but Lorentz boosts are still broken. In this limit, the scattering amplitudes become sensible observables. We relate the soft emission of a Goldstone boson to the (non-relativistic) Lorentz boost of the hard scattering amplitudes. This is the on-shell avatar of the spontaneous breaking of Lorentz boosts, analogous to the Adler zero of pions in the chiral symmetry breaking. We comment on several applications to inflation, including the demonstration that Dirac-Born-Infeld Inflation is the unique theory that has an emergent Lorentz invariance when the boosts are spontaneously broken.

description: This article proposes a critical presentation and development of Alain Badiou's theory of romantic love, at the center of which is an understanding of the phenomenon in terms of a truth-generating event. I discuss this notion against the more familiar ontological modes of theorizing love: as the subject's intentional attitude and as an activity of internal value. Arguing that the evental conception of love poses a preferable alternative to the former mode, my analysis focuses on its complementary relations with the latter, of which I take Stanley Cavell's theory of marriage as a representative. My further argument is concerned with the place of sexuality in the evental conception of love, compensating for what I argue to be the shortcomings of Badiou's treatment of the topic by turning to Roger Scruton's account of the immanent significance of the sexual.

description: Conventional approaches for lattice dynamics based on static interatomic forces do not fully account for the effects of time-reversal-symmetry breaking in magnetic systems. Recent approaches to rectify this involve incorporating the first-order change in forces with atomic velocities under the assumption of adiabatic separation of electronic and nuclear degrees of freedom. In this work, we develop a first-principles method to calculate this velocity-force coupling in extended solids, and show via the example of ferromagnetic CrI$_3$ that, due to the slow dynamics of the spins in the system, the assumption of adiabatic separation can result in large errors for splittings of zone-center chiral modes. We demonstrate that an accurate description of the lattice dynamics requires treating magnons and phonons on the same footing.

description: We study increasing subsequences (IS) for an ensemble of sequences given by permutation of numbers {1,2,...,n}. We consider a Boltzmann ensemble at temperature T. Thus each IS appears with the corresponding Boltzmann probability where the energy is the negative length -l of the IS. For T -> 0, only ground states, i.e. longest IS (LIS) contribute, also called Ulam's problem. We introduce an algorithm which allows us to directly sample IS in perfect equilibrium in polynomial time, for any given sequence and any temperature. Thus, we can study very large sizes. We obtain averages for the first and second moments of number of IS as function of $n$ and confirm analytical predictions. Furthermore, we analyze for low temperature $T$ the sampled ISs by computing the distribution of overlaps and performing hierarchical cluster analyses. In the thermodynamic limit the distribution of overlaps stays broad and the configuration landscape remains complex. Thus, Ulam's problem exhibits replica symmetry breaking. This means it constitutes a model with complex behavior which can be studied numerically exactly in a highly efficient way, in contrast to other RSB-showing models, like spin glasses or NP-hard optimization problems, where no fast exact algorithms are known.

description: This paper studies party-movement interactions in Germany, focusing on Die Linke and the AfD, the two most recent additions to Germany’s multi-party system. The electoral rise of both challenger parties went along with mass protests, opposition to Hartz IV in the mid-2000s and anti-Islamic PEGIDA mobilisation in the mid-2010s. We shift the emphasis from how social movements turn into political parties, including significant organisational and personal overlap, to more indirect ways of how protest and electoral politics interact. Specifically, we identify a process composed of two interrelated mechanisms: an external politicisation spiral and an intra-party innovation spiral. We show how mass protest triggers both discursive shifts in the public sphere and internal strategic realignment, providing an opportunity for parties to ride the wave, secure their competitive advantages, and mobilise on the protestors’ grievances in the electoral arena. In such a way, challenger parties can take advantage of street protests even when they do not directly emerge from a movement. Methodologically, the article is based on a paired comparison, relying on survey data and an original protest event analysis that provides novel data on anti-Hartz IV and PEGIDA protest mobilisation in Germany.

description: Digitales Musik-Erfinden spielt durch die steigende Anzahl an Apps oder Webanwendungen und den niederschwelligen Zugang mittels digitaler Endgeräte sowohl in informellen als auch in formellen Settings eine immer größere Rolle. Besonders für den schulischen Kontext ist dabei zu bedenken, dass Prozesse des Musik-Erfindens häufig als Gruppenarbeit initiiert werden und damit ohnehin eine interaktionale Komplexität aufweisen, die durch die Verortung im Digitalen noch eine Steigerung erfährt. Musikstudierende für Problemstellen und Gelingensbedingungen von Kollaboration in Prozessen digitalen Musik-Erfindens zu sensibilisieren, ist Ziel des hochschuldidaktischen Aufgabenformats. Anhand der künstlerischen Strategie der Soundscape-Composition (in Anlehnung an Vorbilder der 1970er-Jahre um Schafer, Westerkamp und Truax) werden Studierende dazu angeregt, eigene digitale Kollaborationen zu erproben. Anschließend sollen diese Erfahrungen im Hinblick auf die Kollaboration durch geeignete Reflexionsanlässe erschlossen und theoretisiert werden.

Die Sequenz umfasst den Besuch der Ausstellung Jetzt! Junge Malerei in Deutschland im Kunstmuseum Bonn sowie daran anschließende kunstdidaktische Überlegungen. Eine übergeordnete Reflexionsebene, die die Auseinandersetzung mit den in der Ausstellung gezeigten künstlerischen Positionen rahmte, war die Frage nach erkennbar werdenden malerischen Problemstellungen, die mit postdigitalen Konditionen der Sozialisation, des Lebens und des Arbeitens der Künstler*innen in Zusammenhang gebracht werden können. Von diesbezüglichen Eindrücken ausgehend wurde überlegt, inwiefern und unter welchen Bedingungen die Erkundung der erkannten Problemstellungen im Kunstunterricht Reflexionsmöglichkeiten des Einflusses postdigitaler Konditionen auf Wahrnehmungs-, Denk- und Handlungsweisen eröffnen kann. Die Ausstellung bot mit ihrem Fokus auf einer jungen Künstler*innengeneration und auf malerischen sowie metamalerischen Fragestellungen anstelle einer inhaltlichen Rahmung für ein solches Vorgehen besondere Chancen. Im Beitrag soll darüber nachgedacht werden, inwiefern eine entsprechende Analyse zeitgenössischer Kunst allgemeinere Potenziale für Themenfindungen aufweist, anhand derer Momente einer „Kultur der Digitalität“ (Stalder, 2016) in künstlerisch-gestalterischen Arbeiten des Kunstunterrichts relevant und reflexiv werden können.

description: This study focuses on the development of a flow monitoring system that can be integrated with the Liquid Composite Moulding (LCM) process to measure the resin frontal flow propagation. Today, finite element simulations are regularly used to design injection and cure kinetics in the LCM processes. However, purely predictive simulation suffers from issues related to uncertainty and variability in material state and numerous process variables. Thus, the online monitoring of the process is suggested to provide an estimation of the component’s state and to predict potential defects, such as voids and dry spots. The research methodology of the developed system comprises the design of a flexible dielectric sensor and development of a measuring system for the liquid resin infusion process with simplified and complex composite parts. The analysis of the prototype dielectric sensor was performed with the development of an electrostatic model that simulates the behaviour of the sensor during the process and provides information on the sensor capacitance and sensitivity.

description: This paper provides a framework to highlight the entanglement of discovery and historiography based on the example of the rock-relief figure of Karabel (Turkey), a pivotal monument to recognize the Hittites and the biblical past. I lay out the common narrative of the re-discovery's story that resemble a hagiography, and I put it into perspective with critiques from post-colonial studies. Due to the ongoing damage at the figure of Karabel, I hypothesize that the one-sided role of the monument in the story of the re-discovery of the Hittites by western scholars is insufficient to avoid the radical rejection of the Karabel relief by some people. This article is theory-in-practice: it highlights some pitfalls and tells a story with more diversity, open thought, and considerations beyond traditional narratives of power in passéist oriental archaeology.

description: Small amounts of high-capacity silicon-based materials are already used in the anode of commercial Li-ion batteries, helping increase their energy density. Despite their remarkable storage capability, silicon continuously reacts with the electrolyte, accelerating time-dependent cell performance fade. Nevertheless, very limited information is available on the specific consequences of this reactivity for the calendar aging of Li-ion cells. Here, we analyze aging effects on 450 mAh pouch cells containing 15 wt% of Si (and 73 wt% graphite) after storage at 21 oC for four years. We show that severe losses of Si capacity occurred due to particle isolation when cells were stored at high states of charge (SOC), but not when cells were fully discharged prior to storage. Impedance rise was also significantly higher when cells were kept at high SOCs and was mostly due to phenomena taking place at the cathode; the continuous electrolyte reduction at the anode did not lead to a major increase in bulk electrode resistance. A series of post-test characterization provided additional information on the effects of time and SOC on the calendar aging of Si-containing cells. Our study highlights the many challenges posed by Si during calendar aging and can inform future studies in the field.

description: The technological development of the transportation modes, non-fuel-basedvehicleconcept becomes the most challenging customer decision. Using internal combustion engines will cause damages to the environment by producing deleterious emissions and fossil fuels. The movement to alternative fuel vehicles (AEVs) as a sustainable transportation method supports reducing environmental issues. As it found the grey area in knowledge in Risk and benefits in the context of AEVs ,this study aimed to improve the current understanding of the risk-benefit relationship concerning intentions to adopt AFVs. This study is based on five dimensions of perceived values to measure the intention to adopt AFVsby associating perceived risk and consumer attitudes. The current investigation is based on 399 consumers, and the results depicted that quality, price, emotion, social, and ecological values greatly impact consumer attitudes towards AFVs. However, as a moderator, perceived risk impact only social and emotional values with consumer attitudes

description: We investigate the lateral van der Waals (vdW) force between an anisotropic polarizable particle and a perfectly conducting plane with a hemispherical protuberance with radius $R$. We predict, via an exact calculation, a sign inversion in the lateral vdW force, in the sense that, instead of pointing to the protuberance, in certain situations this force points to the opposite direction. In the literature, predictions of sign inversions in the lateral vdW force were based on perturbative solutions, valid when the height of the protuberance is very small when compared to the distance $z_0$ between the particle and the plane. Here, taking into account exact formulas, we investigate how such nontrivial geometric effect depends on the ratio $R/z_0$, and how the particle orientation and anisotropy affect this sign inversion.

title: The good, the bad, and the bloody. Conceptualisations of menstruation across genders and languages
Creators: name: Boughenout, Kamilia M.
Publisher: name: University of Glasgow
Year: 2023

description: Menstruation is a particularly prominent aspect of the life of the many bodies that experience it. From menarche in adolescence to menopause in later life, the implications are not only biological and medical, but also social, cultural and political. Myths, religions, cultures, medicine, and scholarship from diverse fields have concerned themselves with this event for decades, indeed centuries, creating the complex interplay that now informs the menstrual experience and discourse. Yet, beyond anthropologically exploring the status of ‘taboo’ that keeps menstruation hidden, the metaphors in this discourse remain to be fully analysed from a cognitive linguistics perspective. Furthermore, there has been little acknowledgement of gender and linguistic variance within that discourse, particularly of trans individuals and speakers of Arabic and its dialects. There is a wealth of metaphorical expressions that were born within this complex landscape, and that are now used to think and speak about menses, particularly in some types of language and among certain populations. This project aims to fill this gap as it focuses on uncovering the conceptual metaphors of menstruation that exist in everyday language, while including menstruators and non-menstruators alike, as well as speakers of Arabic and its dialect, using a Conceptual Metaphor Theory-based investigation of these metaphors. For this purpose, a survey of participants is first used to gather data which is examined through a semantic tagger, the Historical Thesaurus, and the Mapping Metaphor online tool. This analysis results in the identification of several conceptual metaphors pertaining to the domains PART OF NATURE or NATURAL PART OF LIFE, SOMETHING DIRTY or UPKEEP, PURIFICATION, A PERIOD OF TIME or A PERIOD OF THE HEALTH CYCLE, A HABIT, BLOOD, BLESSING AND TORMENT, A VISITOR, and THE COLOUR RED. Menstruators and non-menstruators rely on those domains and engage in creative coinages of new expressions to create a linguistic point that is informed by their purposes in communication and from which they are able to communicate exactly what and how they want, whether it is to comply with or to defy convention and taboo. Therefore, the usage of menstrual metaphors, beyond its tabooed background and its reflections of societal constraints, is first and foremost a strategic tool for menstruators in particular to be able to accomplish any communicative goal they have in a manner that they deem safe and suitable.

description: We review the known chemistry of the cyaphide ion, (C≡P)−. This remarkable diatomic anion has been the subject of study since the late nineteenth century, however its isolation and characterization eluded chemists for almost a hundred years. In this mini-review, we explore the pioneering and synthetic experiments that first allowed for its isolation, as well as more recent developments demonstrating that cyaphide transfer is viable in well-established salt-metathesis protocols. The physical properties of the cyaphide ion are also explored in depth, allowing us to compare and contrast the chemistry of this ion with that of its lighter congener cyanide (an archetypal strong field ligand and important organic functional group). Recent studies show that the cyaphide ion has the potential to be used as a versatile chemical regent for the synthesis of novel molecules and materials hinting at many interesting future avenues of investigation.

description: In the dry zone of Sri Lanka, human-made reservoirs (locally called tanks or wewas) have served for the collection, storage and distribution of rainfall and runoff and provided irrigation water for the cultivation of paddy for 2400 years. This water management system is deeply inscribed in the rural communities utilizing and maintaining it. Local knowledge connected to the utilization of this system is regarded as a substantial part of the intangible cultural heritage of this unique cultural landscape. In the dry zone of Sri Lanka this system had spread from the fifth century BCE onwards from the hinterland of the ancient capital Anuradhapura throughout the entire dry zone and provides a prerequisite for paddy cultivation. From approximately the 13th century onwards, written sources give evidence, that a weakening of state bureaucracy led to a decline of the water management system. In the Colonial period, numerous reservoirs were restored and the implementation of new governance structures lead to a diminishing of water supplies and conflicts at a local level. In post-Colonial times, since the 1950s, the system had undergone rapid changes triggered by governmental and economic developments (e.g., land use change, migration). The rich local knowledge, serves in line with a high degree of adaptation to local conditions, as a corner stone for its resilience. A future sustainable management requires the integration of local knowledge in combination with modern techniques in education, planning, and application.
Domain-specific and domain-general skills in the identification of conceptually-derived arithmetic strategies

Subjects: subject: 19999 Mathematical Sciences not elsewhere classified

description: Conceptual knowledge of key principles underlying arithmetic is an important precursor to understanding algebra and success in mathematics. One suchprinciple is associativity, which allows groups of operations to be performed in a different order from that in which they are presented. For example, the problem '6 + 38 - 35' can be solved through an efficient 'shortcut' strategyof '38 - 35 = 3' and then 3 + 6 = 9'. One issue is that, of all the widely discussed arithmetic principles associativity is the one that individuals have greatest difficulty with, in that they often fail to apply it when solving arithmetic problems. Educators have called for this to change, and for individuals' knowledge and use of arithmetic principles to improve. This thesis contributes to that goal by investigating the cognitive processes involved in using the associativity shortcut, and the ways in which shortcut use can be encouraged.

description: From 300 BC to AD 300, the city of Pergamon underwent a profound transformation that impacted the rural settlement patterns and the concomitant geomorphodynamics. We present a geoarchaeological study in a long-term settled catchment in the Pergamon micro-region to disentangle the Holocene geomorphodynamics and triggering factors, for example, climate change and human activity. The analyses of eight radiocarbon-dated sediment profiles from the Tekkedere alluvial fan and its catchment indicate four principal sedimentation phases. Phase 1 (ca. 6.2 to 5–4 ka) is dominated by the floodplain aggradation of the receiving Bakırçay River, which is followed by the formation of floodplain soils (phase 2). Substantial geomorphodynamic changes occurred around 4 ka (phase 3), when the edge of the floodplain was buried by fan sediments of the tributary Tekkedere creek. This is attributed to supraregional aridization and rapid climate change events, superimposed by the onset of local human activities. Repeated cycles of coarse- and fine-textured fan sediments with age inversions after ca. 3.8 ka and valley infills younger than 1300 yr BP indicate the strong erosion and redeposition of sediments in phase 4. These increased geomorphodynamics may coincide with the changing settlement pattern and thus reflect human–environment interactions.

description: In this paper, we are going to discuss the gauge reduction with respect to the simplicity constraint in both classical and quantum theory of all dimensional loop quantum gravity. With the gauge reduction with respect to edge-simplicity constraint being proceeded and the anomalous vertex simplicity constraint being imposed weakly in holonomy-flux phase space, the simplicity reduced holonomy can be established. However, we find that the simplicity reduced holonomy can not capture the degrees of freedom of intrinsic curvature, which leads that it fails to construct a correct scalar constraint operator in all dimensional LQG following the standard strategy. To tackle this problem, we establish a new type of holonomy corresponding to the simplicity reduced connection, which captures the degrees of freedom of both intrinsic and extrinsic curvature properly. Based on this new type of holonomy, we propose three new strategies to construct the scalar constraint operators, which serve as valuable candidates to study the dynamics of all dimensional LQG in the future.

description: Avec le MIMO massif, la formation de faisceau (beamforming) et le recours aux ondes millimétriques, les antennes des stations de base poursuivent des évolutions déjà entamées avec les évolutions de la 4G-LTE. De leur côté, les terminaux 5G, fortement contraints par leur taille, doivent bénéficier d’un nouveau stade d’intégration pour pouvoir faire coexister nouvelles bandes de fréquences et nouvelles fonctions en plus des fonctions LTE.

description: The Sloan Digital Sky Survey III's Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a high-resolution near-infrared spectroscopic survey covering all of the major components of the Galaxy, including the dust-obscured regions of the inner Milky Way disk and bulge. Here we present a sample of 10,341 likely red-clump stars (RC) from the first two years of APOGEE operations, selected based on their position in color-metallicity-surface-gravity-effective-temperature space using a new method calibrated using stellar-evolution models and high-quality asteroseismology data. The narrowness of the RC locus in color-metallicity-luminosity space allows us to assign distances to the stars with an accuracy of 5 to 10%. The sample extends to typical distances of about 3 kpc from the Sun, with some stars out to 8 kpc, and spans a volume of approximately 100 kpc^3 over 5 kpc

description: The transverse and longitudinal magnetoresistance (MR) of two samples of the topological chiral semimetal CoSi with different RRR was studied. It is shown that the Kohler rule works for the transverse MR. The Kohler rule is also fulfilled in the case of longitudinal MR at a low reduced magnetic field. A sharp deviation of longitudinal MR curve for sample with low RRR from the Kohler prediction at high fields reveals its tendency to a sign change at higher magnetic fields. The Shubnikov de Haas quantum oscillations were observed and analyzed in both perpendicular and parallel configurations of the current and magnetic field in sample CoSi 1 with RRR 9.33 at low temperatures.

description: We demonstrate that in-bulk vortex localized modes, and their surface half-vortex ("horseshoe") counterparts self-trap in two-dimensional (2D) nonlinear optical systems with $\mathcal{PT}$-symmetric photonic lattices (PLs). The respective stability regions are identified in the underlying parameter space. The in-bulk states are related to truncated nonlinear Bloch waves in gaps of the PL-induced spectrum. The basic vortex and horseshoe modes are built, severally, of four and three beams with appropriate phase shifts between them. Their stable complex counterparts, built of up to 12 beams, are reported too.

description: En prenant le parti pris d’ignorer le contexte macro-économique, la Convention citoyenne a placé le panel de citoyens en lévitation au-dessus de l’économie réelle . Sur le plan énergétique, elle est passée à côté de la relance de l’électricité, alors que celle-ci remplit deux objectifs essentiels, celui de la politique climatique et celui de la localisation de l’activité en France. Peut-on imaginer une Convention citoyenne sur l’activité et l’emploi pour rééquilibrer le projet ?

description: We introduce the concept of the nucleon energy correlators, a set of novel objects that encode the microscopic details of a nucleon, such as the parton angular distribution in a nucleon, the collinear splitting to all orders, as well as the internal transverse dynamics of the nucleon. The nucleon energy correlators complement the conventional nucleon/nucleus tomography, but without introducing the non-perturbative fragmentation functions or the jet clustering algorithms. We demonstrate how the nucleon energy correlators can be measured in the lepton-nucleon deep inelastic scattering. The predicted distributions display a fascinating phase transition between the perturbative and non-perturbative regime. In the perturbative phase, a polar angle version of the Bjorken scaling behavior is predicted. We discuss its possible applications and expect it aggrandize the physics content at the electron ion colliders with a far-forward detector.

Paris compatible emission paths
Paris compatible NDCs

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: Many-body entanglement in condensed matter systems can be diagnosed from equilibrium response functions through the use of entanglement witnesses and operator-specific quantum bounds. Here, we investigate the applicability of this approach for detecting entangled states in quantum systems driven out of equilibrium. We use a multipartite entanglement witness, the quantum Fisher information, to study the dynamics of a paradigmatic fermion chain undergoing a time-dependent change of the Coulomb interaction. Our results show that the quantum Fisher information is able to witness distinct signatures of multipartite entanglement both near and far from equilibrium that are robust against decoherence. We discuss implications of these findings for probing entanglement in light-driven quantum materials with time-resolved optical and x-ray scattering methods.
