description: In course of the organization of Workshop III entitled "Cited References Analysis Using CRExplorer" at the International Conference of the International Society for Scientometrics and Informetrics (ISSI2021), we have prepared three reference publication year spectroscopy (RPYS) analyses: (i) papers published in Journal of Informetrics; (ii) papers regarding the topic altmetrics; and (iii) papers published by Ludo Waltman (we selected this researcher since he received the Derek de Solla Price Memorial Medal during the ISSI2021 conference). The first RPYS analysis has been presented live at the workshop and the second and third RPYS analyses have been left to the participants for undertaking after the workshop. Here, we present the results for all three RPYS analyses. The three analyses have shown quite different seminal papers with a few overlaps. Many of the foundational papers in the field of scientometrics (e.g., distributions of publications and citations, citation network and co-citation analyses, and citation analysis with the aim of impact measurement and research evaluation) were retrieved as seminal papers of the papers published in Journal of Informetrics. Mainly papers with discussions of the deficiencies of citation-based impact measurements and comparisons between altmetrics and citations were retrieved as seminal papers of the topic altmetrics. The RPYS analysis of the paper set published by Ludo Waltman mainly retrieved papers about network analyses, citation relations, and citation impact measurement.

description: In active $φ^4$ field theories the nonequilibrium terms play an important role in describing active phase separation; however, they are irrelevant, in the renormalization group sense, at the critical point. Their irrelevance makes the critical exponents the same as those of the Ising universality class. Despite their irrelevance, they contribute to a nontrivial scaling of the entropy production rate at criticality. We consider the nonequilibrium dynamics of a nonconserved scalar field $φ$ (Model A) driven out-of-equilibrium by a persistent noise that is correlated on a finite timescale $τ$, as in the case of active baths. We perform the computation of the density of entropy production rate $σ$ and we study its scaling near the critical point. We find that similar to the case of active Model A, and although the nonlinearities responsible for nonvanishing entropy production rates in the two models are quite different, the irrelevant parameter $τ$ makes the critical dynamics irreversible.

description: Supramolecular G-quadruplexes (SGQs) are formed via the cation promoted self-assembly of guanine derivatives into stacks of planar hydrogen-bonded tetramers. Here, we present results on the formation of SGQs made from the 8-(m-acetylphenyl)-2′-deoxyguanosine (mAGi) derivative in the presence of various mono- and divalent cations. NMR and HR ESI-MS data indicate that varying the cation can efficiently tune the molecularity, the fidelity and stability (thermal and kinetic) of the resulting SGQs. The results show that, parallel to the previously reported potassium-templated hexadecamer (mAGi16·3K+), Na+, Rb+ and NH4+ also promote the formation of similar supramolecules with high fidelity and molecularity. In contrast, the divalent cations Pb2+, Sr2+ and Ba2+ template the formation of octamers (mAGi8), with the latter two inducing higher thermal stabilities. Molecular dynamics simulations for the hexadecamers containing monovalent cations enabled critical insights that help explain the experimental observations.

description: In this study we map the dualities observed in the framework of integrable probabilities into the dualities familiar in a realm of integrable many-body systems. The dualities between the pairs of stochastic processes involve one representative from Macdonald-Schur family, while the second representative is from stochastic higher spin six-vertex model of TASEP family. We argue that these dualities are counterparts and generalizations of the familiar quantum-quantum (QQ) dualities between pairs of integrable systems. One integrable system from QQ dual pair belongs to the family of inhomogeneous XXZ spin chains, while the second to the Calogero-Moser-Ruijsenaars-Schneider (CM-RS) family. The wave functions of the Hamiltonian system from CM-RS family are known to be related to solutions to (q)KZ equations at the inhomogeneous spin chain side. When the wave function gets substituted by the measure, bilinear in wave functions, a similar correspondence holds true. As an example, we have elaborated in some details a new duality between the discrete-time inhomogeneous multispecies TASEP model on the circle and the quantum Goldfish model from the RS family. We present the precise map of the inhomogeneous multispecies TASEP and 5-vertex model to the trigonometric and rational Goldfish models respectively, where the TASEP local jump rates get identified as the coordinates in the Goldfish model. Some comments concerning the relation of dualities in the stochastic processes with the dualities in SUSY gauge models with surface operators included are made.

description: Recently, interest in using biomineralization for self-healing applications in cement-based materials has gained broader attention in the field. Biomineralization is a biochemical process in which microorganisms stimulate the formation of minerals, and in this particular case calcium carbonate (CaCO3). However, one of the main challenges in biomineralization applications for cement-based materials is that the cell death or insufficient metabolic activity to precipitate CaCO3 may occur when the cells are inoculated in the cement paste matrix. Concerns regarding the viability of the microorganisms within the restrictive and high pH environment of cementbased materials have led to researchers to propose incorporation of endospores rather than metabolically active (vegetative) cells or encapsulation of the endospores. However, a priori encapsulation of the microorganisms might be unnecessary, especially if the bacteria can form endospores. With the proper selection of bacteria and nutrient medium, vegetative microorganisms might also be able to survive for extended periods. This paper summarizes the results of a study undertaken to investigate the influence of vegetative bacteria, Sporosarcina pasteurii (S. pasteurii), when it is incorporated with its growth medium in cement paste. In addition the influence of incorporation of mineral admixtures (Limestone filler and C- type fly ash) on strength of biomineralized mortar was investigated. The efficiency of this vegetative inoculation approach was evaluated using thermogravimetric analysis (TGA), ethanol exchange porosity and compressive strength testing of the biomineralized mortars and metabolic state analysis of S. pasteurii cells by using the Most Probable Number (MPN). The results showed that the vegetative cells were able to induce CaCO3 within the cement paste, which led to a decrease in porosity and an increase in compressive strength. The increase in compressive strength was more pronounced when mineral admixtures were incorporated. Moreover, S. pasteurii cells were found viable in mortar samples up to 330 days.

description: Recently, interest has focused on leveraging the ability of certain microorganisms to improve the performance of porous infrastructure materials by inducing biogenic calcium carbonate precipitation. This biomineralization shows promise in the remediation of cracks in concrete. One concern for biomineralization applications in cementitious materials is that harsh conditions, such as elevated temperature and pH and lack of nutrients, might hinder or prevent bacterial carbonate production in situ. In this study, the surface charge and urease activity of Sporosarcina pasteurii cells that were exposed to moderate heat (55 °C for 4 hours) or suspended in simulated cement paste pore solution (absence of nutrients coupled with pH 13.6) were compared to those of dead cells (killed by autoclaving) or untreated cells. The zeta potential of S. pasteurii cells, which was used to approximate surface charge, was minimally affected by the treatments employed in this study. However, urease activity was greatly influenced. Heat-treated cells exhibited a considerable reduction in urease activity compared to untreated cells, and autoclaved cells or cells suspended in simulated pore solution for 1 day or longer did not exhibit any urease activity. Calcite content in bacterial cement pastes (i.e., cement mixed with bacterial cultures that hydrolyzed urea to produce ammonia and carbonates) was substantially increased as compared to that in neat paste. The results of this study suggest that urea hydrolysis (and concomitant production of carbonates) might be impaired or halted under environmental conditions that occur in cement pastes. However, bacterial surface charge can persist under these conditions, and the bacteria could be important for nucleation of calcium carbonate.

description: The HELIOS-CELESTE hybrid diagnostic (Carolan et al., 2001) is a multi-chord, multi-time active spectroscopic diagnostic attached to the COMPASS-D (Fielding et al., 1996) tokamak. Line intensity ratios from a neutral helium jet are used to measure ne and Te at the plasma edge, making use of emission rates based on a full collisional-radiative model of neutral helium (Summers, 1994). Doppler spectroscopy of HeII ions is used to measure velocity and temperature of those ions in the same region. Synergy of the two diagnostics produce neutral density and radial electric field measurements. Edge Localised Modes (ELMs) (Zohm, 1996) are short, quasi-periodic bursts of particles and energy from the plasma edge, during H-mode (Wagner et al, 1982). A review of ELM phenomenology and theories is presented. A simple model of line intensity of one of the neutral helium lines based on the coronal model is used as a self-consistency check of the HELIOS measurements. Measurements from HELIOS are benchmarked against Thomson scattering measurements. Combining the HELIOS and CELESTE diagnostic is shown to enhance the usefulness of both diagnostics and the synergy is used to lend new insight into Hmode transition behavior, most notably the absence of a radial electric field before the transition into H-mode. Data from the HELIOS diagnostic shows a fall in the edge electron pressure gradient prior to the onset of type III ELMs on COMPASS-D. Data from Thomson scattering and a linear Dα camera on MAST is used to validate the observation. This result is compared with a leading theory of ELM dynamics and is found to contribute to the development of the theory.

description: We study the emergence of dynamical quantum phase transitions (DQPTs) in a half-filled one-dimensional lattice described by the extended Fermi-Hubbard model, based on tensor network simulations. Considering different initial states, namely noninteracting, metallic, insulating spin and charge density waves, we identify several types of sudden interaction quenches which lead to DQPTs. Furthermore, clear connections to particular properties of observables, specifically the mean double occupation or charge imbalance, are established in two main regimes, and scenarios in which such correspondence is degraded and lost are discussed. Dynamical transitions resulting solely from high-frequency time-periodic modulation are also found, which are well described by a Floquet effective Hamiltonian. State-of-the-art cold-atom quantum simulators constitute ideal platforms to implement several reported DQPTs experimentally.

description: An efficient algorithm is required to extract moving objects (asteroids, satellites, and space debris) from enormous data with advances in observational instruments. We have developed an algorithm, tracee, to swiftly detect points aligned as a line segment from a three-dimensional space. The algorithm consists of two steps; First, construct a k-nearest neighbor graph of given points, and then extract colinear line segments by grouping. The proposed algorithm is robust against distractors and works properly even when line segments are crossed. While the algorithm is originally developed for moving object detection, it can be used for other purposes.

Oscillating dynamical friction on galactic bars by trapped dark matter

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The dynamic evolution of galactic bars in standard $Λ$CDM models is dominated by angular momentum loss to the dark matter haloes via dynamical friction. Traditional approximations to dynamical friction are formulated using the linearized collisionless Boltzmann equation and have been shown to be valid in the fast limit, i.e. for rapidly slowing bars. However, the linear assumption breaks down within a few dynamical periods for typical slowly evolving bars, which trap a significant amount of disc stars and dark matter in resonances. Recent observations of the Galactic bar imply this slow regime at the main bar resonances. We formulate the time-dependent dynamical friction in the slow limit and explore its mechanism in the general slow regime with test-particle simulations. Here, angular momentum exchange is dominated by resonantly trapped orbits which slowly librate around the resonances. In typical equilibrium haloes, the initial phase-space density within the trapped zone is higher at lower angular momentum. Since the libration frequency falls towards the separatrix, this density contrast winds up into a phase-space spiral, resulting in a dynamical friction that oscillates with $\sim$Gyr periods and damps over secular timescales. We quantify the long-term behaviour of this torque with secular perturbation theory, and predict two observable consequences: i) The phase-space spirals may be detectable in the stellar disc where the number of windings encodes the age of the bar. ii) The torque causes weak oscillations in the bar's pattern speed, overlaying the overall slowdown -- while not discussed, this feature is visible in previous simulations.

description: In order to control the demand for the use of Portland cement as well as to increase the durability of structure, although commercial admixtures are available that imparts additional cost for the construction projects. To enhance the mechanical property of Portland cement, a greener alternative solution needs to be investigated. Bacteria deposits calcium carbonate by the phenomenon called bio-cementation or microbiologically induced calcite precipitation (MICP). The present study aimed to analyse the improvement in compressive strength of ordinary Portland cement (OPC 53 grade) by addition of soil bacterial solution. In all casting for nine cubes each for controlled and bio-OPC were carried out. Experimentally, three cubes from each set were studied for compressive strength at the age of 7, 14 and 28 days. The effect of peptone and lentil seed as the protein source to soil bacteria was also analysed. At the age of 28 days, as compared to the controlled OPC 53 grade cubes, on an average 15.26 and 15.73 % improvement in compressive strength was estimated for peptone and lentil based bio-OPC respectively. Scanning electron microscopy (SEM) study was carried out and revealed the precipitation of calcite in the microbial amended cement specimen. The growth of calcite crystals within the pores of the cement matrix was observed. As compared to peptone solution, the lentil seeds are cost effective protein source to the soil bacteria and also impart in gaining more strength. The approach of bio-cementation is found to be commercially viable and environment friendly technique.

description: Parametric computer-aided design (CAD) tools are the predominant way that engineers specify physical structures, from bicycle pedals to airplanes to printed circuit boards. The key characteristic of parametric CAD is that design intent is encoded not only via geometric primitives, but also by parameterized constraints between the elements. This relational specification can be viewed as the construction of a constraint program, allowing edits to coherently propagate to other parts of the design. Machine learning offers the intriguing possibility of accelerating the design process via generative modeling of these structures, enabling new tools such as autocompletion, constraint inference, and conditional synthesis. In this work, we present such an approach to generative modeling of parametric CAD sketches, which constitute the basic computational building blocks of modern mechanical design. Our model, trained on real-world designs from the SketchGraphs dataset, autoregressively synthesizes sketches as sequences of primitives, with initial coordinates, and constraints that reference back to the sampled primitives. As samples from the model match the constraint graph representation used in standard CAD software, they may be directly imported, solved, and edited according to downstream design tasks. In addition, we condition the model on various contexts, including partial sketches (primers) and images of hand-drawn sketches. Evaluation of the proposed approach demonstrates its ability to synthesize realistic CAD sketches and its potential to aid the mechanical design workflow.

description: Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua. In particular, odd moduli arising from the reduction of 2-forms $(B_2,C_2)$ in type IIB are largely unexplored despite their relevance for inflationary model building. This article provides novel insights into the general structure of 4D $\mathcal{N}=1$ $F$-term scalar potentials at higher orders in the $α^{\prime}$ and $g_{s}$ expansion for arbitrary Hodge numbers. We systematically examine superpotential contributions with distinct moduli dependences which are induced by fluxes or non-perturbative effects. Initially, we prove the existence of a no-scale structure for odd moduli in the presence of $(α^\prime)^{3}$ corrections to the Kähler potential. By studying a partially $\mathrm{SL}(2,\mathbb{Z})$-completed form of the Kähler potential, we derive the exact no-scale breaking effects at the closed string $1$-loop and non-perturbative D-instanton level. These observations allow us to present rigorous expressions for the $F$-term scalar potential applicable to arbitrary numbers of moduli in type IIB Calabi-Yau orientifold compactifications. Finally, we compute the Hessian for odd moduli and discuss potential phenomenological implications.

description: Motivated by recent experiments [P. Vaidya {\em et al.}, Science {\bf 368}, 160 (2020)] on spin pumping from sub-THz radiation-driven uniaxial antiferromagnetic insulator (AFI) MnF$_2$ into heavy metal (HM) Pt hosting strong spin-orbit (SO) coupling, we compute and compare pumped spin currents in Cu/MnF$_2$/Cu and Pt/MnF$_2$/Cu heterostructures. Recent theories of spin pumping by AFI have relied on simplistic Hamiltonians (such as tight-binding) and the scattering approach to quantum transport yielding the so-called interfacial spin mixing conductance (SMC), but the concept of SMC ceases to be applicable when SO coupling is present directly at the interface. In contrast, we use more general first-principles quantum transport approach which combines noncollinear density functional theory with Floquet-nonequilibrium Green's functions in order to take into account: {\em SO-proximitized AFI} as a new type of quantum material, different from isolated AFI and brought about by AFI hybridization with adjacent HM layer; SO coupling at interfaces; and evanescent wavefunctions penetrating from Pt or Cu into AFI layer to make its interfacial region {\em conducting} rather than insulating as in the original AFI. The DC component of pumped spin current $I_\mathrm{DC}^{S_z}$ vs. precession cone angle $θ_{\vb*{l}}$ of the Néel vector $\vb*{l}$ of AFI {\em does not} follow putative $I^{S_z}_\mathrm{DC} \propto \sin^2 θ_{\vb*{l}}$, except for very small angles $θ_{\vb*{l}} \lesssim 10^\circ$ for which we can define an {\em effective} SMC from the prefactor and find that it doubles from MnF$_2$/Cu to MnF$_2$/Pt interface. In addition, the angular dependence $I^{S_z}_\mathrm{DC}(θ_{\vb*{l}})$ differs for opposite directions of precession of the Néel vector, leading to twice as large SMC for the right-handed than for the left-handed chirality of the precession mode.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: We exploit the effect of light-induced atomic desorption to produce high atomic densities ($n\gg k^3$) in a rubidium vapor cell. An intense off-resonant laser is pulsed for roughly one nanosecond on a micrometer-sized sapphire-coated cell, which results in the desorption of atomic clouds from both internal surfaces. We probe the transient atomic density evolution by time-resolved absorption spectroscopy.With a temporal resolution of $\approx1\,\mathrm{ns}$, we measure the broadening and line shift of the atomic resonances. Both broadening and line shift are attributed to dipole-dipole interactions. This fast switching of the atomic density and dipolar interactions could be the basis for future quantum devices based on the excitation blockade.

description: Understanding how deep convolutional neural networks classify data has been subject to extensive research. This paper proposes a technique to visualize and interpret intermediate layers of unsupervised deep convolutional networks by averaging over individual feature maps in each convolutional layer and inferring underlying distributions of words with non-linear regression techniques. A GAN-based architecture (ciwGAN arXiv:2006.02951) that includes a Generator, a Discriminator, and a classifier was trained on unlabeled sliced lexical items from TIMIT. The training process results in a deep convolutional network that learns to classify words into discrete classes only from the requirement of the Generator to output informative data. This classifier network has no access to the training data -- only to the generated data. We propose a technique to visualize individual convolutional layers in the classifier that yields highly informative time-series data for each convolutional layer and apply it to unobserved test data. Using non-linear regression, we infer underlying distributions for each word which allows us to analyze both absolute values and shapes of individual words at different convolutional layers, as well as perform hypothesis testing on their acoustic properties. The technique also allows us to test individual phone contrasts and how they are represented at each layer.

In this description, the QCD axion is represented by a Kalb-Ramond field which is eaten-up by the Chern-Simons $3$-form of QCD, thereby making it massive. This ensures the CP-invariance of the vacuum. Although viewed as an effective low energy theory, this formulation accomplishes the same goal as ordinary Peccei-Quinn mechanism, due to its gauge invariance, it is protected against unwanted UV-corrections. In the previous work it has been shown that dual formulation is insensitive to UV-physics in the sense that the corrections to CP-conserving vacuum from arbitrary massive sources are strictly zero. By going carefully through duality transformations and source-resolution, we reproduce this curious result and give some further consistency checks. We apply similar analysis to other approaches to naturalness problems based on form fields and axions, such as cosmological relaxation of the standard model Higgs boson mass via the attractor mechanism.

description: Camouflaging gate techniques are typically used in hardware security to prevent reverse engineering. Layout level camouflaging by adding dummy contacts ensures some level of protection against extracting the correct netlist. Threshold voltage manipulation for multi-functional logic with identical layouts has also been introduced for functional obfuscation. All these techniques are implemented at the expense of circuit-complexity and with significant area, energy, and delay penalty. In this paper, we propose an efficient hardware encryption technique with minimal complexity and overheads based on ferroelectric field-effect transistor (FeFET) active interconnects. The active interconnect provides run-time reconfigurable inverter-buffer logic by utilizing the threshold voltage programmability of the FeFETs. Our method utilizes only two FeFETs and an inverter to realize the masking function compared to recent reconfigurable logic gate implementations using several FeFETs and complex differential logic. We fabricate the proposed circuit and demonstrate the functionality. Judicious placement of the proposed logic in the IC makes it acts as a hardware encryption key and enables encoding and decoding of the functional output without affecting the critical path timing delay. Also, we achieve comparable encryption probability with a limited number of encryption units. In addition, we show a peripheral programming scheme for reconfigurable logic by reusing the existing scan chain logic, hence obviating the need for specialized programming logic and circuitry for keybit distribution. Our analysis shows an average encryption probability of 97.43% with an increase of 2.24%/ 3.67% delay for the most critical path/ sum of 100 critical paths delay for ISCAS85 benchmarks.

description: Motivated by fine tuning of the magnetic and topological properties of MnBi$_2$Te$_4$ via defect engineering, in this work, we report the crystal growth of MnBi$_2$Te$_4$ and related compounds using vapor transport method and characterization of vapor transported crystals by measuring elemental analysis, magnetic and transport properties, and scanning tunneling microscopy. For the growth of MnBi$_2$Te$_4$ single crystals, I$_2$, MnI$_2$ , MnCl$_2$, TeCl$_4$, or MoCl$_5$ are all effective transport agents; chemical transportation occurs faster in the presence of iodides than chlorides. MnBi$_2$Te$_4$ crystals can be obtained in the temperature range 500$^\circ$C-590$^\circ$C using I$_2$ as the transport agent. We further successfully grow MnSb$_2$Te$_4$, MnBi$_{2-x}$Sb$_x$Te$_4$, and Sb-doped MnBi$_4$Te$_7$ crystals. A small temperature gradient $

description: We propose a method for generation of entangled photonic states in high dimensions, the so-called qudits, by exploiting quantum correlations of Orbital Angular Momentum (OAM) entangled photons, produced via Spontaneous Parametric Down Conversion. Diffraction masks containing $N$ angular slits placed in the path of twin photons define a qudit space of dimension $N^2$, spanned by the alternative pathways of OAM-entangled photons. We quantify the high-dimensional entanglement of path-entangled photons by the Concurrence, using an analytic expression valid for pure states. We report numerical results for the Concurrence as a function of the angular aperture size for the case of high-dimensional OAM entanglement and for the case of high-dimensional path entanglement, produced by $N \times M$ angular slits. Our results provide additional means for preparation and characterization of entangled quantum states in high-dimensions, a fundamental resource for quantum simulation and quantum information protocols.

description: Speed of state transitions in macroscopic systems is a crucial concept for foundations of nonequilibrium statistical mechanics as well as various applications in quantum technology represented by optimal quantum control. While extensive studies have made efforts to obtain rigorous constraints on dynamical processes since Mandelstam and Tamm, speed limits that provide tight bounds for macroscopic transitions have remained elusive. Here, by employing the local conservation law of probability, the fundamental principle in physics, we develop a general framework for deriving qualitatively tighter speed limits for macroscopic systems than many conventional ones. We show for the first time that the speed of the expectation value of an observable defined on an arbitrary graph, which can describe general many-body systems, is bounded by the "gradient" of the observable, in contrast with conventional speed limits depending on the entire range of the observable. This framework enables us to derive novel quantum speed limits for macroscopic unitary dynamics. Unlike previous bounds, the speed limit decreases when the expectation value of the transition Hamiltonian increases; this intuitively describes a new tradeoff relation between time and quantum phase difference. Our bound is dependent on instantaneous quantum states and thus can achieve the equality condition, which is conceptually distinct from the Lieb-Robinson bound. Our work elucidates novel speed limits on the basis of local conservation law, providing fundamental limits to various types of nonequilibrium quantum macroscopic phenomena.

title: Divided world versus one world: A comparative analysis of non-continuous text elements in school geography textbooks of international selection

description: Otherness is embodied in geography in regionalization. Regions with similar respectively different ecological, economical, social, and cultural features have been traditionally clustered on global scale in "worlds". While political and economical factors played an important role in distinguishing between the First, Second, and Third World during the Cold War, clustering developed and developing regions considers also additional aspects such as resources, education, or technology. Stressing more the aspects of convergence rather than the ones of divergence, contemporary discourses build on the idea of (education for) sustainable development in an undivided "one world". Textbooks for school geography contain along with the continuous text also a multitude of non-continuous text elements that carry an expressive and very contrastive iconography of the "own" and the "other". This paper deals with the question, how otherness is expressed through non-continuous text (e.g. maps, diagrams, cartoons, pictures etc.). We argue that otherness is often expressed through self-inclusion respectively self-exclusion of the own country on a global level. For that, the paper compares a sample of secondary school geography texts from Germany (Western context), Romania (post-socialist context), and Mexico (post-colonial context). Qualitative content analysis of the meta-text elements (Pingel 2010) was carried out. The results show that non-continuous text divides worlds by classifying and clustering on several scales, while cross-curricular coordinates contribute to a converging one world. The results also show that a new regionalization based on concept of sustainable development seems to be emerging.

description: Solid-state refrigeration based on caloric effects is an energetically efficient and environmentally friendly technology, which is deemed as a potential alternative to the conventional vapor-compression technology. One of the greatest obstacles to the real application is the huge driving fields. Here, we report a giant barocaloric effect in inorganic NH4I with maximum entropy changes of ΔS_BCE^max ~89 J K-1 kg-1 around room temperature, associated with the orientationally order-disorder phase transition. The phase transition temperature, Tt, varies dramatically with pressure in a rate of dTt/dP ~0.81 K MPa-1, which leads to a very much small saturation driving pressure of ΔP ~20 MPa, an unprecedentedly large caloric strength of |ΔS_BCE^max/ΔP| ~4.45 J K-1 kg-1 MPa-1, as well as a broad temperature window of ~68 K under an 80 MPa driving pressure. Comprehensive characterization of the crystal structure and dynamics by neutron scattering measurements reveals a strong reorientation-vibration coupling that is responsible for the large pressure sensitivity of Tt. This work is expected to advance the practical application of barocaloric refrigeration.

Balanced B and D-type orthosymplectic quivers -- Magnetic quivers for product theories

description: We investigate orthosymplectic quivers that take the shape of D-type and B-type Dynkin diagrams. The D-type orthosymplectic quivers explored here contain a balanced "fork", i.e., a balanced subquiver with a D-type bifurcation, whereas the B-type orthosymplectic quivers are obtained by folding the D-type quivers. The Coulomb branches of these quivers are products of two moduli spaces. In the second part, the relevant orthosymplectic quivers are shown to emerge as magnetic quivers for brane configurations involving ON$^0$ planes. Notably, the appearance of ON$^0$ plane clarifies the product nature of the theories in question. The derivation leads to the analysis of magnetic quivers from branes systems with intersecting Op, O(p+2), and ON$^0$ planes.
