description: openCost: The Road to Publication Cost Transparency, openCost 2022, Hamburg, Germany, 5 Oct 2022 - 7 Oct 2022
description: Founded more than 10 years ago, the JOIN² collaboration brings together eight research institutions for the development and operation of a full-fledged shared scholarly publication database and repository based on the Invenio open source framework for large-scale digital libraries. Preferring simplicity to complexity one of our corner stones is to build on well-defined work flows. This enabled JOIN² to extend it's services from representing the scholarly output of the member institutions to serve as the open access repository on site and gradually add additional services. One of these is the management of publication cost data along side the publications within the repository. From the start we headed to model all cost we came across in scholarly publishing, be it open or closed access to further cost transparency. This naturally led JOIN² to be one of the core members of openCost, with DESY representing the collaboration. After a very short introduction who we are the talk focuses on the status of JOIN² as an openCost cost data provider and makes a suggestion how we could imagine to expose our data to other services like OpenAPC. This includes a suggestion for a metadata format as well as the structure on how to expose it for easy automatic aggregation. We outline some open points with regard to a further standardization that will allow also other institutions to adopt this format and the automatic delivery processes involved and that should be addressed during the workshop.

description: Magnetism - the spontaneous alignment of atomic moments in a material - is driven by quantum-mechanical `exchange' interactions which operate over atomic distances as a result of the fundamental symmetry of electrons. Currently, one of the most active fields of condensed matter physics involves the study of magnetic interactions that cause, or are caused by a twisting of nearby atoms. This can lead to the magnetoelectric effect that couples electric and magnetic properties, and is predicted to play a prominent role in future technology. Here, we discuss the complex relativistic interplay between magnetism and atomic crystal structure in a class of materials called `weak ferromagnets'. The sign of the underpinning Dzyaloshinskii--Moriya interaction has been determined for the first time, by using synchrotron radiation to study iron borate (FeBO3). We present a novel experimental technique based on interference between two x-ray scattering processes (one acts as a reference wave) which we combine with a second unusual approach of turning the atomic antiferromagnetic motif with a small magnetic field. We show that the experimental results provide a clear validation of state-of-the-art theoretical calculations. These experimental and theoretical approaches open up new possibilities for exploring, modelling and exploiting novel magnetic and magnetoelectric materials.

description: Wasserkraft ist in der Schweiz die wichtigste Quelle erneuerbarer Energie. Rund 60 Prozent vom Schweizer Strommix stammen aus Wasserkraftanlagen. Eine zuverlässige Energieversorgung im Kontext der Energiewende ist bis auf Bundesebene ein gewichtiges Thema. Im «Bundesgesetz über eine sichere Stromversorgung mit erneuerbaren Energien», welches vom Schweizer Volk im Juni 2024 angenommen wurde, sind 15 Ausbauvorhaben von Speicherwasserkraftwerken festgehalten. Eines davon, ist das Projekt «Speichersee und Kraftwerk Trift» im Gadmertal in der Gemeinde Innertkirchen.

Seit knapp einem Jahrhundert produzieren die Kraftwerke Oberhasli AG (KWO) Strom aus Wasserkraft. Derzeit jährlich für rund 1.2 Millionen Menschen in der Schweiz. Die grössten Speicherseen im Einzugsgebiet der KWO befinden sich heute entlang der Aare im Grimselgebiet. Mit dem Trift-Projekt, soll neu auch im Gadmertal ein Speichersee von grossem Ausmass entstehen. Abgesehen von den Effekten auf die nationale Stromversorgung, haben solche Bauprojekte auch Folgen für die ansässige Bevölkerung und Wirtschaft. Auswirkungen können sowohl ökologischer, ökonomischer oder auch sozialer Natur sein und vielfältige Veränderungen auslösen. Wie diese zugunsten der regionalökonomischen Entwicklung in der Standortgemeinde Innertkirchen sowie in der gesamten Region Haslital Brienz genutzt werden können, wurde in dieser Arbeit untersucht. Konkret erörtert diese Master- Arbeit Bereiche mit Wertschöpfungspotential und formuliert Handlungsoptionen für die Gemeinde Innertkirchen sowie die Region Haslital Brienz, um langfristig vom Projekt «Speichersee und Kraftwerk Trift» profitieren zu können. Als Hauptgrundlage für die Beantwortung der Fragestellung dienten Literaturrecherchen sowie die Durchführung von teilstrukturierten Expert*inneninterviews. Mithilfe einer Szenario- und einer SWOT-Analyse wurden die Ergebnisse der Erhebungen untersucht und verarbeitet.

In fünf Bereichen konnten Wertschöpfungspotentiale und spezifische Handlungsoptionen ermittelt werden. Unter anderem durch gezielte Weiterentwicklung vom sanften Tourismus im Gadmertal oder durch Massnahmen zur Förderung eines regionalen Energie-Clusters. Als wichtigste Erkenntnis konnte die hohe Bedeutung der Etablierung einer dauerhaften, offenen und breit abgestützten Beteiligungskultur dargelegt werden. Diese bildet den Grundstein zur optimalen Nutzung des Wertschöpfungspotentials im Zusammenhang mit dem Trift-Projekt.

German PP-dislocations to the left and to the right: Against a symmetric approach

description: We consider the discourse functions of PP-dislocations to the left (PP-LD) and to the right (PP-RD) in German. Whilst it is often assumed that these constructions are symmetric, we argue that they differ in a crucial way. In the majority of cases PP-LD is built with the clause-internal proform da (approx.: ‘there’), and the PP serves to restrict a ‘topic situation’ da refers to. PP-RD, on the contrary, is only possible with a clause-internal proform consisting of a preposition + pronoun. Cases where da as clause-internal proform is used with a coreferent PP to the right of the sentence are shown to be ‘afterthoughts’, i.e. repair constructions.

description: The doped perovskite BaBiO$_3$ exhibits a maximum superconducting transition temperature ($T_c$) of 34 K and was the first high-$T_c$ oxide to be discovered, yet pivotal questions regarding the nature of both the metallic and superconducting states remain unresolved. Although it is generally thought that superconductivity in the bismuthates is of the conventional s-wave type, the pairing mechanism is still debated, with strong electron-phonon coupling and bismuth valence or bond disproportionation possibly playing a role. Here we use diffuse x-ray scattering and Monte Carlo modeling to study the local structure of Ba$_{1-x}$K$_x$BiO$_3$ across its insulator-metal boundary. We find no evidence for either long- or short-range disproportionation, which resolves a major conundrum, as disproportionation and the related polaronic effects are likely not relevant for the metallic and superconducting states. Instead, we uncover nanoscale structural correlations that break inversion symmetry, which has far-reaching implications for the electronic physics, including the pairing mechanism. This unexpected finding furthermore establishes that the bismuthates belong to the broader classes of materials with hidden spin-orbit coupling and a tendency towards inversion-breaking displacements.

description: In this paper I investigate the interpretation of pronouns in modal contexts. I focus on dream reports, taking Lakoff’s (1972) Brigitte Bardot examples as a starting point. I show that different pronouns behave differently in this context, and propose an analysis that makes use of Percus and Sauerland’s (2003) LF proposal, but is restricted to first person pronouns. I also show that to capture the full range of data, we need put restrictions on the counterpart relations available to individuals in a given context.

description: We present a study of the faint-end of the X-ray Luminosity Function of Low Mass X-ray binaries in the Globular Cluster system of the cD galaxy NGC 1399 by performing a stacking experiment on 618 X-ray undetected GCs, in order to verify the presence of faint LMXBs and to constrain the faint-end slope of the GC-LMXBs XLF below the individual detection threshold of $8\times10^{37}$ erg s$^{-1}$ in the $0.5-8$ keV band. We obtain a significant X-ray detection for the whole GC sample, as well as for the red and blue GC subpopulations, corresponding to an average luminosity per GC $_{GC}$ of $(3.6\pm1.0)\times10^{36}\ erg\ s^{-1}$, $(6.9\pm2.1)\times10^{36}\ erg\ s^{-1}$ and $(1.7\pm0.9)\times10^{36}\ erg\ s^{-1}$, respectively for all, red and blue GCs. If LMXBs in red and blue GCs have the same average intrinsic luminosity, we derive a red/blu ratio $\simeq 3$ of GCs hosting LMXBs ($2.5\pm1.0$ or $4.1\pm2.5$ depending on the surveyed region); alternatively, assuming the fractions observed for brighter sources, we measure an average X-ray luminosity of $L_{X}=(4.3\pm1.3)\times10^{37}\ erg\ s^{-1}$ and $L_{X}=(3.4\pm1.7)\times10^{37}\ erg\ s^{-1}$ per red and blue GC-LMXBs respectively. In the assumption that the XLF follows a power-law distribution, we find that a low-luminosity break is required at $L_{X}\leq 8\times10^{37}$ erg s$^{-1}$ both in the whole, as well as in the color-selected (red and blue) subsamples. Given the bright-end slopes measured above the X-ray completeness limit, this result is significant at $>3σ$ level. Our best estimates for the faint end slope are $β_{L}=-1.39/-1.38/-1.36$ for all/red/blue GC-LMXBs. We also find evidence that the luminosity function becomes steeper at luminosities $L_X\gtrsim 3\times 10^{39}$ erg s$^{-1}$, as observed in old ellipticals.

Instrument, culture and myth: disclosure of 'thinking process material' under the Freedom of Information Act 1982 (Cth)

description: Transparency is at the heart of modern democracy. Transparency in relation to how government makes decisions and develops policy is particularly important. It underpins accountability, combats corruption and enhances the ability of the public to participate in democratic processes. In Australia one way to access this information is by making a request under the Freedom of Information Act 1982. However, this right of access is not unlimited, and the effectiveness of Freedom of Information (FOI) law depends in key ways on public servants, who are responsible both for creating much of the material upon which FOI law ‘bites’ and for deciding whether it should be disclosed according to the legal framework. Little is known about how public servants approach these tasks. This thesis, therefore, explores how Australian Government public servants respond to freedom of information (FOI) requests for documents showing the ‘thinking process’ of government. This thesis uses doctrinal analysis, an FOI case study and interviews with public servants and other key figures to examine the factors that influence FOI practice and decision-making. Through the lens of organisational theory, it recognises that FOI decisions are not made in a vacuum and may be influenced by the context in which they are made as well as by the law. This thesis concludes that the way that public servants interpret and apply FOI law is influenced by a combination of factors, including the legislative framework, cultural norms and values and the principles of Public Value Management. This thesis finds that in some cases, the legal obligation to disclose thinking process material is viewed as ‘out of step’ with the values, norms and working practices of public servants. In such cases, public servants have found ways to work around the legislation. This thesis concludes, therefore, that current FOI law is a ‘myth’. It is symbolically important as a way of representing the Government’s commitment to transparency, but is in practice an ineffective tool for promoting the disclosure of thinking process material.

According to Ehrenfest's classification, when the parameters in the theory are arranged properly the BTZ black hole with torsion may posses the second order phase transition which is also a smaller mass/larger mass black hole phase transition. Nevertheless, the critical behavior is different from the one in the van der Waals liquid/gas system. We also calculated the critical exponents of the relevant thermodynamic quantities, which are the same as the ones obtained in the Hořava-Lifshitz black hole and the Born-Infeld black hole.

Even and free choice any in Hungarian
Creators: name: Abrusán, Márta
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper presents an analysis of the Hungarian free-choice indefinite akárki ‘anyone’. It is observed that akárki is composed of a special type of focus particle akár ‘even’ which itself, in its focus-particle existence has a free-choice-like distribution, and of a wh-indefinite. To account for the special properties of akár ‘even’, it is argued that akár is composed of even plus an Exhaustive Operator (O). As the additive presupposition of even and the lexical meaning of the Exhaustive Operator are contradictory, this combination results in ungrammaticality, unless a suitable operator (e.g. an existential modal or a DE operator) intervenes. In the second part of the paper it is shown that the core distribution of free choice indefinites in Hungarian simply follows from the meaning of the incorporated akár. The universal-like meaning of free choice items arises as an inference from the combination of the standard existential additive presupposition and the universal scalar presupposition.

description: It is time for Nigeria to feed Nigerians with the aim of actualizing the United Nation’s Sustainable Development Goals in the area of zero hunger (food security). Recent statistics show increasing food insecurity issues; the global COVID 19 pandemic has further worsened the country’s food (in)security situation. This study econometrically assessed the nexus of agricultural credit and sustainable food production in Nigeria. Secondary data on variables of interest were gotten from World Development Indicators (WDI) of the World Bank and other relevant bodies. The data were analyzed using Unit Root Test (URT) and the Fully Modified Ordinary Least Square (FMOLS). The study revealed that Agricultural Credit Guarantee Scheme Fund (ACGSF) and loan to agriculture from the commercial banks statistically and positively influenced food security within the study period. Lending interest rate and official exchange rate inversely influenced food security. The study concluded that credit is key to achieving self-sufficiency in food production. The post estimation tests on the models confirmed that policy implications from this study are applicable to improving food security. Proper and efficient policy mix to support agricultural production including provision of credit was recommended

description: In this paper, we study a double scaling limit of two multi-matrix models: the $U(N)^2 \times O(D)$-invariant model with all quartic interactions and the bipartite $U(N) \times O(D)$-invariant model with tetrahedral interaction ($D$ being here the number of matrices and $N$ being the size of each matrix). Those models admit a double, large $N$ and large $D$ expansion. While $N$ tracks the genus of the Feynman graphs, $D$ tracks another quantity called the grade. In both models, we rewrite the sum over Feynman graphs at fixed genus and grade as a finite sum over combinatorial objects called schemes. This is a result of combinatorial nature which remains true in the quantum mechanical setting and in quantum field theory. Then we proceed to the double scaling limit at large $D$, i.e. for vanishing grade. In particular, we find that the most singular schemes, in both models, are the same as those found in Benedetti et al. for the $U(N)^2 \times O(D)$-invariant model restricted to its tetrahedral interaction. This is a different universality class than in the 1-matrix model whose double scaling is not summable.

description: We construct a novel class of exact solutions to the Boltzmann equation, in both its classical and quantum formulation, for arbitrary collision laws. When the system is subjected to a specific external forcing, the precise form of which is worked out, non equilibrium damping-less solutions are admissible. They do not contradict the $H$-theorem, but are constructed from its requirements. Interestingly, these solutions hold for time-dependent confinement. We exploit them, in a reverse-engineering perspective, to work out a protocol that shortcuts any adiabatic transformation between two equilibrium states in an arbitrarily short time-span, for an interacting system. Particle simulations of the direct Monte Carlo type fully corroborate the analytical predictions.

description: A generalization of modularity, called block modularity, is defined. This is a quality function which evaluates a label assignment against an arbitrary block pattern. Therefore, unlike standard modularity or its variants, arbitrary network structures can be compared and an optimal block matrix can be determined. Some simple algorithms for optimising block modularity are described and applied on networks with planted structure. In many cases the planted structure is recovered. Cases where it is not are analysed and it is found that strong degree-correlations explain the planted structure so that the discovered pattern is more `surprising' than the planted one under the configuration model. Some well studied networks are analysed with this new method, which is found to automatically deconstruct the network in a very useful way for creating a summary of its key features.

description: Chiral perturbation theory and its unitarized versions have played an important role in our understanding of the low-energy strong interaction. Yet, so far, such studies typically deal exclusively with perturbative or nonperturbative channels. In this letter, we report on the first global study of meson-baryon scattering up to one-loop order. It is shown that covariant baryon chiral perturbation theory, including its unitarization for the negative strangeness sector, can describe meson-baryon scattering data remarkably well. This provides a highly non-trivial check on the validity of this important low-energy effective field theory of QCD. We show that the $\bar{K}N$ related quantities can be better described in comparison with those of lower-order studies, and with reduced uncertainties due to the stringent constraints from the $πN$ and $K N$ phase shifts. In particular, we find that the two-pole structure of $Λ(1405)$ persists up to one-loop order reinforcing the existence of two-pole structures in dynamically generated states.

Accounting for the “causal link” between free adjuncts and their host clauses
Creators: name: Zobel, Sarah
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper investigates the causal interpretation of free adjuncts. These are non-clausal adjuncts that associate with an individual denoted by an argument of the main verb and contribute propositional content about that individual (e.g., being an Englishman in John, being an Englishman, is brave). Based on a comparison with since-clauses, I analyze causally interpreted free adjuncts as contributing presuppositional propositional content that provides supporting evidence for the speaker’s main claim. I argue that the “causal link” responsible for this interpretation is not contributed by the free adjunct but inferred. I propose that it is pragmatically necessary that the presuppositional content of the free adjunct is linked to the truth-conditional content of the host clause and that the causal flavor follows from general pragmatic requirements placed on the assertion act.

Founding Women in Medieval French Prose Romance

description: The thesis entitled ‘Founding Women in Medieval French Prose Romance’ analyses the important role given to foundresses in the fictional works of 13th and 14th century romanciers. The study of three genealogical texts – Jean d’Arras’ Roman de Mélusine, the prehistory of the Tristan en Prose, and the Roman de Perceforest illustrate first and foremost the limits of the widely accepted assertion regarding the ‘absence’ of women in genealogical narratives of the time. I argue, on the contrary, that for these medieval authors women constitute an untapped source of literary potential, since by the 13th century all possible narratives surrounding Europe’s founding fathers were virtually exhausted. These female characters thus champion the creation of new narratives that run parallel to previous literature, but they also function as precious intertextual grafts that enable the romance author to tie his work to his literary precedents, guaranteeing a status of legitimacy to his own creation. By exploring the narrative trajectories of foundresses such as Mélusine, Presine (Mélusine), Chelinde (Tristan), Cerses and Lydoire (Peceforest) I show how these texts propose a new literary relationship tying fictional women to medieval romances: indeed, in these works the roles of generator of genealogy and generator of genealogical text become increasingly confused; thus, founding women often represent narrative trajectories which can support as much as run counter to that of their author. This unique quality, which marks these female characters against the passive and silent voices of their courtly counterparts, is due to the linguistic quality of lineage in these romances. Through an anthropological perspective I show how these texts envision kinship relations not as natural, blood bonds, but rather as linguistic alliances. Fictional foundresses are given the remarkable privilege to voice or deny these alliances, and thus to call the genealogy – and the romance itself – into being. Characters such as Presine and Lydoire, for example, are endowed with an authorial voice which allows them to craft their lineage on their own terms and even direct the narrative outside of the romance itself, towards new and unexpected intertexts; yet even passive characters such as Chelinde, Mélusine and Cerses are given the means to voice their own histories. What this research makes clear is that at a time when, in Capetian France, women were being increasingly excluded from power and even their very role in producing legitimate heirs is being questioned, the fictional foundresses of prose romances not only place themselves at the head of powerful lineages: they also write alternative histories of the world, and finally weave a textual genealogy for their romances, one able to create a network that encompasses all of European history.

description: We construct microscopical models of one-dimensional non-interacting topological insulators in all of the chiral universality classes. Specifically, we start with a deformation of the Su-Schrieffer-Heeger (SSH) model that breaks time-reversal symmetry, which is in the AIII class. We then couple this model to its time-reversal counterpart in order to build models in the classes BDI, CII, DIII and CI. We find that the $\mathbb{Z}$ topological index (the winding number) in individual chains is defined only up to a sign. This comes from noticing that changing the sign of the chiral symmetry operator changes the sign of the winding number. The freedom to choose the sign of the chiral symmetry operator on each chain independently allows us to construct two distinct possible chiral symmetry operators when the chains are weakly coupled -- in one case, the total winding number is given by the sum of the winding number of individual chains while in the second case, the difference is taken. We find that the chiral models that belong to $\mathbb{Z}$ classes, AIII, BDI and CII are topologically equivalent, so they can be adiabatically deformed into one another so long as the chiral symmetry is preserved. We study the properties of the edge states in the constructed models and prove that topologically protected edge states must all be localised on the same sublattice (on any given edge). We also discuss the role of particle-hole symmetry on the protection of edge states and explain how it manages to protect edge states in $\mathbb{Z}_2$ classes, where the integer invariant vanishes and chiral symmetry alone does not protect the edge states anymore. We discuss applications of our results to the case of an arbitrary number of coupled chains, construct possible chiral symmetry operators for the multiple chain case, and briefly discuss the generalisation to any odd number of dimensions.

description: In recent years, 3D cell cultures (organoids and tumor spheroids) has generated great interest in biological engineering because they seem to allow a better representation of biological complexity than monolayer cell cultures. However, few works have yet focused on the detailed analysis of the levels of molecular and cellular similarity between different 3D culture models and with the corresponding reference tissues.
 We have developed a bioinformatics framework to facilitate the advanced analysis of transcriptomes from multiple experimental conditions of 3D cell cultures. We have setup a strategy to generate controlled cell mixtures from single cell RNA-seq data of reference tissues and to use them to assess the biological complexity of 3D cell cultures.
 We applied our approach to analyze the transcriptomes of blood vessel organoids and we were able to identify the experimental conditions allowing to better recapitulate the biology of the reference tissue.

description: Magnetic reconnection is ubiquitous in astrophysical systems, and in many such systems, the plasma suffers from significant cooling due to synchrotron radiation. We study relativistic magnetic reconnection in the presence of strong synchrotron cooling, where the ambient magnetization $σ$ is high and the magnetic compactness $\ell_{B}$ of the system is of order unity. In this regime, $e^{\pm}$ pair production from synchrotron photons is inevitable, and this process can regulate the magnetization $σ$ surrounding the current sheet. We investigate this self-regulation analytically and find a self-consistent steady state for a given magnetic compactness of the system and initial magnetization. This result helps estimate the self-consistent upstream magnetization in systems where plasma density is poorly constrained, and can be useful for a variety of astrophysical systems. As illustrative examples, we apply it to study the properties of reconnecting current sheets near the supermassive black hole of M87, as well as the equatorial current sheet outside the light cylinder of the Crab pulsar.

description: Mean-field theory links the physiological properties of individual neurons to the emergent dynamics of neural population activity. These models provide an essential tool for studying brain function at different scales; however, for their application to neural populations on large scale, they need to account for differences between distinct neuron types. The Izhikevich single neuron model can account for a broad range of different neuron types and spiking patterns, thus rendering it an optimal candidate for a mean-field theoretic treatment of brain dynamics in heterogeneous networks. Here, we derive the mean-field equations for networks of all-to-all coupled Izhikevich neurons with heterogeneous spiking thresholds. Using methods from bifurcation theory, we examine the conditions under which the mean-field theory accurately predicts the dynamics of the Izhikevich neuron network. To this end, we focus on three important features of the Izhikevich model that are subject here to simplifying assumptions: (i) spike-frequency adaptation, (ii) the spike reset conditions, and (iii) the distribution of single-cell spike thresholds across neurons. Our results indicate that, while the mean-field model is not an exact model of the Izhikevich network dynamics, it faithfully captures its different dynamic regimes and phase transitions. We thus present a mean-field model that can represent different neuron types and spiking dynamics. The model is comprised of biophysical state variables and parameters, incorporates realistic spike resetting conditions, and accounts for heterogeneity in neural spiking thresholds. These features allow for a broad applicability of the model as well as for a direct comparison to experimental data.

description: Programmable quantum systems based on Rydberg atom arrays have recently been used for hardware-efficient tests of quantum optimization algorithms [Ebadi et al., Science, 376, 1209 (2022)] with hundreds of qubits. In particular, the maximum independent set problem on so-called unit-disk graphs, was shown to be efficiently encodable in such a quantum system. Here, we extend the classes of problems that can be efficiently encoded in Rydberg arrays by constructing explicit mappings from a wide class of problems to maximum weighted independent set problems on unit-disk graphs, with at most a quadratic overhead in the number of qubits. We analyze several examples, including: maximum weighted independent set on graphs with arbitrary connectivity, quadratic unconstrained binary optimization problems with arbitrary or restricted connectivity, and integer factorization. Numerical simulations on small system sizes indicate that the adiabatic time scale for solving the mapped problems is strongly correlated with that of the original problems. Our work provides a blueprint for using Rydberg atom arrays to solve a wide range of combinatorial optimization problems with arbitrary connectivity, beyond the restrictions imposed by the hardware geometry.

Partitives, multipliers and subatomic quantification

description: In standard lattice-theoretic approaches to natural language (e.g., Link, 1983, Landman, 2000, Champollion, 2017) singularities and pluralities are presumed to involve two distinct mereological structures and it is commonly supposed that quantificational expressions do not access subatomic part-whole relations. In this paper, I argue that i) certain quantificational expressions are sensitive to subatomic part-whole structures, ii) quantification over parts is subject to identical restrictions as quantification over wholes and iii) counting presupposes certain topological relations. I present new evidence in favor of a mereotopological approach to natural language (cf. Grimm, 2012) as well as novel data concerning the interaction between quantification and subatomic part-whole relations.

description: A number of studies have found that participants are less likely to interpret the scalar words ‘some’ and ‘or’ with an upper bound when their cognitive resources are burdened, thus suggesting that the computation of scalar inferences is cognitively effortful. We conducted two sentence-picture verification tasks to determine whether this finding generalises to other scalar words. In Exp. 1, we manipulated cognitive load by asking participants to memorise simple or complex grid patterns during the experiment (cf. De Neys and Schaeken, 2007). In Exp. 2, we manipulated cognitive load by varying the time participants could take to process the sentences and pictures (cf. Chevallier et al., 2008). In this way, we tested seven scalar words: ‘some’, ‘or’, ‘low’, ‘scarce’, ‘might’, ‘most’, and ‘try’. We expected to find lower rates of scalar inferences when participants experienced greater cognitive load, i.e., when they had to memorise complex grid patterns in Exp. 1, and when they had less processing time available in Exp. 2. We find significant effects of memory load in the expected direction, but only for positively scalar words, i.e., for scalar words that denote a lower bound. We fail to find any significant effects of processing time. We explain these findings by arguing that the scalar inferences of positively scalar words introduce negative information into the meaning of the sentence, and that the processing of such negative information is cognitively demanding.

description: Opening a band gap and realizing static valley control have been long sought after in graphenebased two-dimensional (2D) materials. Motivated by the recent success in synthesizing 2D materials passivated by Si-N layers, here, we propose two new graphene-based materials, 2D C2SiN and CSiN, via first-principles calculations. Monolayer C2SiN is metallic and realizes superconductivity at low temperatures. Monolayer CSiN enjoys excellent stability and mechanical property. It is a semiconductor with a ternary valley structure for electron carriers. Distinct from existing valleytronic platforms, these valleys can be controlled by applied uniaxial strain. The valley polarization of carriers further manifest as a pronounced change in the anisotropic conductivity, which can be detected in simple electric measurement. The strong interaction effects also lead to large exciton binding energy and enhance the optical absorption in the ultraviolet range. Our work opens a new route to achieve superconductivity, ternary valley structure, and semiconductor with enhanced optical absorption in 2D materials.

description: The microscopic origin of the $γ$-softness (fluctuations in the triaxiality parameter $γ$ of the nuclear shape) observed in atomic nuclei is studied in the framework of the triaxial projected shell model approach, which is based on the deformed mean-field picture with multi-quasiparticle configuration space. It is demonstrated that the coupling to quasiparticle excitations drives the system from a $γ$-rigid to a $γ$-soft pattern. As an illustrative example for a $γ$-soft nucleus, a detailed study has been performed for the $^{104}$Ru nucleus. The experimental energies and a large sample of measured $E2$ matrix elements available for this nucleus are reproduced quite accurately. The shape invariant analysis of the calculated $E2$ matrix elements elucidates the $γ$-soft nature of $^{104}$Ru.
