description: According to the Griffith criterion, a crack propagation occurs provided that the derivative of the energy functional with respect to the crack length reaches some critical value. We consider a generalization of this criterion to the case of nonlinear cracks satisfying a non-penetration condition and investigate the dependence of the shape derivative of the energy functional on the crack shape. In the paper, we find the crack shape which gives the maximal deviation of the energy functional derivative from a given critical value and, in particular, prove that this optimality problem admits a solution.

description: Experimental studies with ultracold atoms have enabled major breakthroughs in understanding three-body physics, historically a fundamental yet challenging problem. This is because the interactions among ultracold atoms can be precisely varied using magnetically tunable scattering resonances known as Feshbach resonances. The collisions of ultracold atoms have been discovered to have many universal aspects near the unitarity limit. Away from this limit, many quantum states are expected to be active during a three-body collision, making the collisional observables practically unpredictable. Here we report a major development in predicting three-body ultracold scattering rates by properly building in the pairwise van der Waals interactions plus the multi-spin properties of a tunable Feshbach resonance state characterized by two known dimensionless two-body parameters. Numerical solution of the Schr{ö}dinger equation then predicts the three-atom collisional rates without adjustable fitting parameters needed to fit data. Our calculations show quantitative agreement in magnitude and feature position and shape across the full range of tuning of measured rate coefficients for three-body recombination and atom-dimer collisions involving ultracold Cs atoms.

Extending Agents by Transmitting Protocols in Open Systems

description: Agents in an open system communicate using interaction protocols. Suppose that we have a system of agents and that we want to add a new protocol that all (or some) agents should be able to understand. Clearly, modifying the source code for each agent implementation is not practical. A solution to this problem of upgrading an open system is to have a mechanism that allows agents to receive a description of an interaction protocol and use it. In this paper we propose a representation for protocols based on extending Petri nets. However, this is not enough: in an open system the source of a protocol may not be trusted and a protocol that is received may contain steps that are erroneous or that make confidential information public. We therefore also describe an analysis method that infers whether a protocol is safe. Finally, we give an execution model for extended Petri nets.

Temporal Propositional De Se: Evidence from Romanian Subjunctive Mood
Creators: name: Brasoveanu, Adrian
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The paper investigates the interpretation of the Romanian subjunctive B (subjB) mood when it is embedded under the propositional attitude verb crede (believe). SubjB is analyzed as a single package of three distinct presuppositions: temporal de se, dissociation and propositional de se. I show that subjB is the temporal analogue of null PRO in the individual domain: it allows only for a de se reading. Dissociation enables us to show that subjB always takes scope over a negation embedded in a belief report. Propositional de se derives this empirical generalization. The introduction of centered propositions (generalizing centered worlds), together with propositional de se, dissociation and the belief 'introspection' principles, derives the fact that subjB belief reports (unlike their indicative counterparts) are infelicitous with embedded probabil.

TV Phenomenon

description: "From Sitio Pongayan to La Presa: Transforming a Cordilleran Community through a Prime Time TV Series" is a video documentary and ethnographic study that examined how Sitio Pongayan, a small Cordilleran Community, was transformed into the famous La Presa because of a prime time TV Series called Forevermore (2014).
 Guided by the Social Construction of Reality Theory (Peter L. Berger and Thomas Luckmann) which included the three-part model by Adoni and Mane (1984), and Cultivation Theory by George Gerbner, this study was able to find some answers on how this TV phenomenon created significant community developments in Sitio Pongayan.
 The study also identified different relevant texts, forms, and themes that constructed meanings, experiences, and realities created by the show about Sitio Pongayan, the people, and the culture. It also gave answers on how these constructed meanings, experiences, and realities affected the community's image, the people, and Forevermore's supporters. The results also included some discussions from local leaders, residents, and experts about this TV phenomenon.
 Since this research only focused on how Sitio Pongayan transformed into La Presa because of a TV series, the author recommended other researchers to discover more places in the country that could be affected by media-induced community development using Development Communication approaches. There is also a need to explore and evaluate other alternative media platforms (online media), TV genres/formats, and different time slots that are relevant in creating community developments similar to what Forevermore had done.

description: We consider a subclass of bipartite CHSH-type Bell inequalities. We investigate operations, which leave their Tsirelson bound invariant, but change their classical bound. The optimal observables are unaffected except for a relative rotation of the two laboratories. We illustrate the utility of these operations by giving explicit examples: We prove that for a fixed quantum state and fixed measurement setup except for a relative rotation of the two laboratories, there is a Bell inequality that is maximally violated for this rotation, and we optimise some Bell inequalities with respect to the maximal violation. Finally we optimise the qutrit to qubit ratio of some dimension witnessing Bell inequalities.

Ever heard of ethical AI? Investigating the salience of ethical AI issues among the German population

description: Building and implementing ethical AI systems that benefit the whole society is cost-intensive and a multi-faceted task fraught with potential problems. While computer science focuses mostly on the technical questions to mitigate social issues, social science addresses citizens' perceptions to elucidate social and political demands that influence the societal implementation of AI systems. Thus, in this study, we explore the salience of AI issues in the public with an emphasis on ethical criteria to investigate whether it is likely that ethical AI is actively requested by the population. Between May 2020 and April 2021, we conducted 15 surveys asking the German population about the most important AI-related issues (total of N=14,988 respondents). Our results show that the majority of respondents were not concerned with AI at all. However, it can be seen that general interest in AI and a higher educational level are predictive of some engagement with AI. Among those, who reported having thought about AI, specific applications (e.g., autonomous driving) were by far the most mentioned topics. Ethical issues are voiced only by a small subset of citizens with fairness, accountability, and transparency being the least mentioned ones. These have been identified in several ethical guidelines (including the EU Commission's proposal) as key elements for the development of ethical AI. The salience of ethical issues affects the behavioral intentions of citizens in the way that they 1) tend to avoid AI technology and 2) engage in public discussions about AI. We conclude that the low level of ethical implications may pose a serious problem for the actual implementation of ethical AI for the Common Good and emphasize that those who are presumably most affected by ethical issues of AI are especially unaware of ethical risks. Yet, once ethical AI is top of the mind, there is some potential for activism.

description: This paper presents a compositional semantic analysis of pluractional adverbial modifiers like 'dog after dog' and 'one dog after the other'. We propose a division of labour according to which much of the semantics is carried by a family of plural operators. The adverbial itself contributes a semantics that we call pseudoreciprocal.

Complex Focus Versus Double Focus
Creators: name: Balogh, Kata
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The main aim of this paper is to point out several problems with the semantic analysis of Hungarian focus interpretation and ‘only’. For current semantic analyses the interpretation of Hungarian identificational/exhaustive focus and ‘only’ is problematic, since in classical semantic analyses ‘only’ is identified with an exhaustivity operator. In this paper I will discuss multiple focus constructions and question-answer pairs in Hungarian to show that such a view cannot be applied to Hungarian exhaustive focus. Next to this I will discuss possible interpretations of Hungarian sentences containing multiple prosodic foci: complex focus versus double focus. My claim is that in order to interpret multiple focus (in Hungar- ian) we have to take into consideration the different intonation patterns, the occurrence of ‘only’, and the syntactic structure as well.

description: Die Jugendphase ist gekennzeichnet durch eine Vielzahl von Erwartungen und Herausforderungen. So gilt es für die Jugendlichen, neben den alltäglichen Anforderungen des Lebens, zahlreiche Entwicklungsaufgaben zu meistern – und dies in einer Gesellschaft, welche durch Individualisierung und Globalisierung immer schnelllebiger und komplexer geworden ist. Daher überrascht es nicht, dass in aktuellen Befragungen viele Jugendliche angeben, unter Stress zu leiden und sich Hilfe im Umgang mit diesem wünschen. Ein Ort, wo ihnen diese Unterstützung zukommen kann, ist die Schulsozialarbeit, deren Aufgabe es unter anderem ist, Kinder und Jugendliche bei ihren Herausforderungen zu begleiten und Hilfe zu bieten. Basil R. Dembinski und Simone Manser wollten mit dieser Arbeit herausfinden, wie Schulsozialarbeiter:innen1 im Kanton Zug das Stresserleben von Jugendlichen einschätzen und was sie unternehmen, um Stress entgegenzuwirken. Unter dem Titel Handlungsmöglichkeiten der Schulsozialarbeit bei stressbelasteten Jugendlichen in der Sekundarstufe 1 wurden sechs von ihnen in qualitativen Interviews befragt, wie sie das Thema Stress bei Jugendlichen einschätzen und was sie in den Bereichen Prävention, Frühintervention und Beratung zu Stress machen. So zeigte sich, dass Stress – obwohl in der täglichen Arbeit der Schulsozialarbeit omnipräsent – auch wegen seiner vielseitigen Erscheinungsformen und Ursachen nicht nach einem starren Schema oder Konzept abgearbeitet werden kann. Und es zeigte sich, dass vermutlich viel erreicht werden könnte, wenn die Schulsozialarbeit bei stressbelasteten Jugendlichen frühzeitiger beigezogen würde, als dies heute häufig der Fall ist.

The 'Separate Performative' Account of the German Right Dislocation
Creators: name: Averintseva-Klisch, Maria
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In my paper, I show that the so-called German right dislocation actually comprises two distinct constructions, which I label 'right dislocation proper' and 'afterthought'. These differ in their prosodic and syntactic properties, as well as in their discourse functions. The paper is primarily concerned with the right dislocation proper (RD). I present a semantic analysis of RD based on the ‘separate performative’ account of Potts (2004, 2005) and Portner (forthc.). This analysis allows a description of the semantic contribution of RD to its host sentence, as well as explaining certain semantic constraints on the kind of NP in the RD construction.

While P6$_3$/m is the most likely candidate for phase III at the nuclear ground state, at finite temperature the C2/c structure appears to be more suitable.

description: We present a Boundary Local Fourier Analysis (BLFA) to optimize the relaxation parameters of boundary conditions in a multigrid framework. The method is implemented to solve elliptic equations on curved domains embedded in a uniform Cartesian mesh, although it is designed to be extended for general PDEs in curved domains, wherever a multigrid technique can be implemented. The boundary is implicitly defined by a level-set function and a ghost-point technique is employed to treat the boundary conditions. Existing strategies in literature adopt a constant relaxation parameter on the whole boundary. In this paper, the relaxation parameters are optimized in terms of the distance between ghost points and boundary, with the goal of smoothing the residual along the tangential direction. Theoretical results are confirmed by several numerical tests in 1D, 2D and 3D, showing that the convergence factor associated with the smoothing on internal equations is not degraded by boundary effects.

description: Due to their higher planet-star mass-ratios, M dwarfs are the easiest targets for detection of low-mass planets orbiting nearby stars using Doppler spectroscopy. Furthermore, because of their low masses and luminosities, Doppler measurements enable the detection of low-mass planets in their habitable zones that correspond to closer orbits than for Solar-type stars. We re-analyse literature UVES radial velocities of 41 nearby M dwarfs in a combination with new velocities obtained from publicly available spectra from the HARPS-ESO spectrograph of these stars in an attempt to constrain any low-amplitude Keplerian signals. We apply Bayesian signal detection criteria, together with posterior sampling techniques, in combination with noise models that take into account correlations in the data and obtain estimates for the number of planet candidates in the sample. More generally, we use the estimated detection probability function to calculate the occurrence rate of low-mass planets around nearby M dwarfs. We report eight new planet candidates in the sample (orbiting GJ 27.1, GJ 160.2, GJ 180, GJ 229, GJ 422, and GJ 682), including two new multiplanet systems, and confirm two previously known candidates in the GJ 433 system based on detections of Keplerian signals in the combined UVES and HARPS radial velocity data that cannot be explained by periodic and/or quasiperiodic phenomena related to stellar activities. Finally, we use the estimated detection probability function to calculate the occurrence rate of low-mass planets around nearby M dwarfs. According to our results, M dwarfs are hosts to an abundance of low-mass planets and the occurrence rate of planets less massive than 10 M$_{\oplus}$ is of the order of one planet per star, possibly even greater. ...

Cognitive Representation and the Relevance of On-line Constructions
Creators: name: Assimakopoulos, Stavros
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper, focusing on the relevance-theoretic view of cognition, I discuss the idea that what is communicated through an utterance is not merely an explicature upon which implicature(s) are recovered, but rather a propositional complex that contains both explicit and implicit information. More specifically, I propose that this information is constructed on the fly as the interpreter processes every lexical item in its turn while parsing the utterance in real time, in this way creating a string of ad hoc concepts. While hearing an utterance and incrementally constructing a context, the propositional complex communicated by an utterance is pragmatically narrowed and simultaneously pragmatically broadened in order to incorporate only the set of optimally relevant propositions with respect to a specific point in the interpretation. The narrowing of propositions from the initial context at each stage allows relevant propositions to be carried on to the new level, while their broadening adds to the communicated propositional complex new propositions that are linked to the lexical item that is processed at every step of the interpretation process.

Quantifying question particles in German: syntactic effects on interpretation
Creators: name: Zimmermann, Malte
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The paper presents an analysis of the German quantifying question particles (QQPs) w-so and w-alles. It is shown that the syntactic position of these particles, i.e. their formal association with a particular wh-item, is relevant for their semantic representation, contrary to claims in Beck (1996). The effects of syntactic structure on semantic interpretation are captured by treating QQPs as modifiers on structured propositions that place additional restrictions on the question domain introduced by the wh-item: w-so introduces a plurality condition on the answer space, whereas w-alles has two meaning components: next to adding a plurality condition, it indicates that the question requires an exhaustive answer. The existence of explicit markers of exhaustiveness in wh-questions has important consequences for the analysis of wh-questions as inherently exhaustive (Groenendijk & Stokhof 1982, 1984) or not (Beck & Rullmann 1999).

description: Properties of the SO(2,n) Yangian acting on scalar and gauge fields are presented. This differential operator representation of the infinite-dimensional extension of the conformal algebra SO(2,n) is proved to satisfy the Serre relation for arbitrary spacetime dimension n for off-shell scalar theory, but only on shell and for n=4 in the gauge theory. The SO(2,n) Yangian acts simply on the off-shell kinematic invariants $(k_I+k_{I+1}+ ...)^2$, and it annihilates individual off-shell scalar $λϕ^3$ Feynman tree graphs for n=6 if the differential operator representation is extended by graph dependent evaluation terms. The SO(2,4) Yangian level one generators are shown to act in a compact way on pure Yang-Mills gluon tree amplitudes. The action of the Yangian on the scattering polynomials of a CHY formalism is also described.

For 2 x d-dimensional state, it is shown that UIN can be given by a closed form. In addition, we also investigate the maximal uncertainty-induced nonlocality.

description: Low-mass X-ray binaries (LMXBs) are a natural workbench to study accretion disk phenomena and optimal background sources to measure elemental abundances in the Interstellar medium (ISM). In high-resolution XMM-Newton spectra, the LMXB SAX J1808.4-3658 showed in the past a neon column density significantly higher than expected given its small distance, presumably due to additional absorption from a neon-rich circumstellar medium (CSM). It is possible to detect intrinsic absorption from the CSM by evidence of Keplerian motions or outflows. For this purpose, we use a recent, deep (100 ks long), high-resolution Chandra/LETGS spectrum of SAX J1808.4-3658 in combination with archival data. We estimated the column densities of the different absorbers through the study of their absorption lines. We used both empirical and physical models involving photo- and collisional-ionization in order to determine the nature of the absorbers. The abundances of the cold interstellar gas match the solar values as expected given the proximity of the X-ray source. For the first time in this source, we detected neon and oxygen blueshifted absorption lines that can be well modeled with outflowing photoionized gas. The wind is neon rich (Ne/O>3) and may originate from processed, ionized gas near the accretion disk or its corona. The kinematics (v=500-1000 km/s) are indeed similar to those seen in other accretion disks. We also discovered a system of emission lines with very high Doppler velocities (v~24000 km/s) originating presumably closer to the compact object. Additional observations and UV coverage are needed to accurately determine the wind abundances and its ionization structure.

description: The high cosmic abundance and the intermediate volatility and chemical properties of sulfur allow the use of sulfur-bearing species as a tracer of the chemical processes in the atmospheres of hot Jupiter exoplanets. Nevertheless, despite its properties and relevance as a tracer of the giant planets' formation history, little attention has been paid to this species in the context of hot Jupiter atmospheres. Here we provide an overview of the abundances of sulfur-bearing species in hot Jupiter atmospheres under different conditions and explore their observability. We use the photochemical kinetics code VULCAN to model hot Jupiter atmospheric disequilibrium chemistry. Transmission spectra for these atmospheres are created using the modelling framework ARCiS. We vary model parameters such as the diffusion coefficient, and we study the importance of photochemistry on the resulting mixing ratios. Furthermore, we vary the chemical composition of the atmosphere by increasing the metallicity from solar to ~10 times solar. We also explore different C/O ratios. We find that H2S and SO2 are the best candidates for detection between 1 and 10 micron, using a spectral resolution that is representative of the instruments on board the JWST. H2S is easiest to detect at an equilibrium temperature of ~1500 K and C/O ratios between 0.7 and 0.9, with the ideal value increasing slightly for increasing metallicity. SO2 is most likely to be detected at an equilibrium temperature of ~1000 K at low C/O ratios and high metallicities. Nevertheless, among these two molecules, we expect SO2 detection to be more common, as it is detectable in scenarios more favoured by formation models. We conclude that H2S and SO2 will most likely be detected in the coming years with the JWST and that the detection of these species will provide information on atmospheric processes and planet formation scenarios.

description: The STAR experiment has measured $pΛ$, $\bar{p}\barΛ$, $\bar{p}Λ$, and $p\barΛ$ femtoscopic correlation functions in central Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV. The system size extracted for $pΛ$ and $\bar{p}\barΛ$ is consistent with model expectations and results for other pair types, while for $p\barΛ$ and $\bar{p}Λ$ it is not consistent with the other two and significantly lower. In addition an attempt was made to extract the unknown parameters of the strong interaction potential for this baryon-antibaryon ($B\bar{B}$) pair. In this work we reanalyze the STAR data, taking into account residual femtoscopic correlations from heavier $B\bar{B}$ pairs. We obtain new estimates for the system size, consistent with the results for $pΛ$ and $\bar{p}\barΛ$ pairs and with model expectations. We give new estimates for the strong interaction potential parameters for $p\barΛ$ and show that similar constraints can be given for parameters for other, heavier $B\bar{B}$ pairs.

description: Postnominal modifiers license unexpected opaque readings of demonstrative descriptions. This paper presents a unified analysis of ordinary demonstrative descriptions and the special construction consisting of an opaque demonstrative description with a postnominal modifier. The analysis is based on two independently necessary components: a modal constraint associated with demonstrative determiners and the modal independence of postnominal modifiers. Far from being a peripheral construction, opaque demonstratives ultimately allow us to probe the interaction of nominal constituents with modality.

description: Many authors have argued that there exists a relation between case morphology, on the one hand, and semantic interpretation, on the other. A recurrent pattern is that the presence of overt case corresponds with a strong interpretation, i.e., deﬁnite, speciﬁc, whereas the absence of case corresponds with a weak interpretation, i.e., indeﬁnite, non-speciﬁc. In this paper we argue on the basis of differential object marking (DOM) data that such an across- the-board correlation between semantic interpretation and case morphology often cannot be maintained as the association between a certain case and a certain interpretation can be counteracted by the requirement of this case to occur due to the animacy of a noun. The fact that animacy takes priority over deﬁniteness and/or speciﬁcity in DOM systems can be explained by the fact that animacy, but not deﬁniteness/speciﬁcity, is an inherent feature of nouns, a feature which cannot be changed.

description: We show that tree-level form factors with length-two operators in Yang-Mills-scalar (YMS) theory exhibit structures very similar to scattering amplitudes of gluons and scalars, which leads to new relations between them. Just like amplitudes, $n$-point Yang-Mills form factors with ${\rm tr}(F^2)$ operator can be decomposed as a linear combination of form factors with ${\rm tr}(ϕ^2)$ operator and $r$ external scalars in YMS theory, where the coefficients are given by Lorentz products of the $r$ linearized field strengths. Moreover, we show that any such $n$-point form factor of ${\rm tr}(ϕ^2)$ operator can be further expanded into $(n{+}1)$-point YMS amplitudes with an additional off-shell scalar leg. In addition to unravelling hidden structures, our results provide an efficient algorithm for computing all-multiplicity length-two form factors in any dimension, as well as their Cachazo-He-Yuan formulae via those of the YMS amplitudes.

description: Non-radiative wireless power transfer (WPT) technology has made considerable progress with the application of the parity-time (PT) symmetry concept. In this letter, we extend the standard second-order PT-symmetric Hamiltonian to high-order symmetric tridiagonal pseudo-Hermitian Hamiltonian, relaxing the limitation of multi-source/multi-load system based on non-Hermitian physics. We proposed a three-mode pseudo-Hermitian dual-transmitter-single-receiver circuit and demonstrate that robust efficiency and stable frequency WPT can be achieved even though PT-symmetry is not satisfied as usual. In addition, no active tuning is required when the coupling coefficient between the intermediate transmitter and the receiver is changed. Moreover, the proposed system has an open frequency band gap with an abrupt frequency change at the phase transition point, which is expected to advance wireless sensing technologies.

description: The soilless farming system is an exclusive technique of growing plants with the out use of soil in the large-scale farms owned by a few exporters in Jordan. The research offers an economic analysis of this soilless system for sustainable water and land use. It deals with the socio-economic compared to the conventional farming system. Two types of questionnaires were used to collect data from both systems; 32 and 68 farms, respectively. The socioeconomics was analyzed using cost-benefit Analysis. The results show the efficiency of the soilless system concerning irrigation, enhancing agricultural productivity and returns. The adopters receive a higher income, where 40% of them get more income compared to 20% in the conventional system. Furthermore, the cost-benefit analysis confirms its high profitability according to different indicators. The economic, and environmental benefits are sufficient and convincing reasons to make soilless agriculture the most agricultural practical method to accommodate growing trends in sustainability and development.
Global potential energy surface for the O2 + N2 interaction. Applications to the collisional, spectroscopic, and thermodynamic properties of the complex

description: A detailed characterization of the interaction between the most abundant molecules in air is important for the understanding of a variety of phenomena in atmospherical science. A completely {\em ab initio} global potential energy surface (PES) for the O$_2(^3Σ^-_g)$ + N$_2(^1Σ^+_g)$ interaction is reported for the first time. It has been obtained with the symmetry-adapted perturbation theory utilizing a density functional description of monomers [SAPT(DFT)] extended to treat the interaction involving high-spin open-shell complexes. The computed interaction energies of the complex are in a good agreement with those obtained by using the spin-restricted coupled cluster methodology with singles, doubles and noniterative triple excitations [RCCSD(T)]. A spherical harmonics expansion containing a large number of terms due to the anisotropy of the interaction has been built from the {\em ab initio} data. The radial coefficients of the expansion are matched in the long range with the analytical functions based on the recent {\em ab initio} calculations of the electric properties of the monomers [M. Bartolomei et al., J. Comp. Chem., {\bf 32}, 279 (2011)]. The PES is tested against the second virial coefficient $B(T)$ data and the integral cross sections measured with rotationally hot effusive beams, leading in both cases to a very good agreement. The first bound states of the complex have been computed and relevant spectroscopic features of the interacting complex are reported. A comparison with a previous experimentally derived PES is also provided.
A parallel account of epistemic modals and predicates of personal taste
Creators: name: Stephenson, Tamina
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Epistemic modals (might, must) and predicates of personal taste (tasty, fun) show parallel behavior related to whose knowledge or taste is relevant for their interpretation. To account for the similarity, I extend Lasersohn’s (2005) account of predicates of personal taste to epistemic modals, using his “judge” parameter for the person whose knowledge is relevant. Along the way, I argue for modifications to Lasersohn’s view. I also propose a way to place the account in a Stalnakerian theory of conversation.

Nonperturbatively Renormalized Nucleon Gluon Momentum Fraction in the Continuum Limit of $N_f=2+1+1$ Lattice QCD

description: We present the nonperturbatively renormalized nucleon gluon momentum fraction using ensembles with $2+1+1$ flavors of highly improved staggered quarks (HISQ), generated by MILC Collaboration. The calculation is done using clover fermions for the valence action with three pion masses, $220$, $310$ and $690$ MeV and three lattice spacings, 0.09, 0.12, and 0.15 fm. The renormalization is done using RI/MOM nonperturbative renormalization and using cluster-decomposition error reduction (CDER) to enhance the signal-to-noise ratio of the renormalization constant. We find the CDER technique is particularly important to improve the signal at the finer lattice ensembles where the lattice volume is larger. We extrapolate the gluon momentum fraction to the continuum-physical limit and obtain $\langle x \rangle_g = 0.492(52)_\text{stat.+NPR}(49)_\text{mixing}$ in the $\bar{\text{MS}}$ scheme at 2 GeV, where first error includes the statistical error and uncertainties in nonperturbative renormalization, while the latter systematic accounts for ignoring quark mixing. Our gluon momentum fraction is consistent with other recent lattice-QCD results at physical pion mass.

description: We provide a rigorous mathematical framework to establish the hydrodynamic limit of the Vlasov model introduced by Noguchi and Takata in order to describe phase transition of fluids by kinetic equations. We prove that, when the scale parameter tends to 0, this model converges to a nonlocal Cahn-Hilliard equation with degenerate mobility. For our analysis, we introduce apropriate forms of the short and long range potentials which allow us to derive Helmhotlz free energy estimates. Several compactness properties follow from the energy, the energy dissipation and kinetic averaging lemmas. In particular we prove a new weak compactness bound on the flux.

Reciprocal equatives
Creators: name: Schwarz, Bernhard
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: A sentence like John and Mary are equally heavy conveys that John and Mary are as heavy as each other and can be characterized as a reciprocal equative. This paper discusses reciprocal equatives and inequatives in German. It explores the construction as novel source of evidence concerning the scopal properties of degree quantification. Specifically, reciprocal equatives are argued to provide evidence for the view that degree operators can take inverse scope over modal operators and can take scope outside DPs containing them at the surface (Heim 1999, 2001).

On frequency adjectives
Creators: name: Schäfer, Roland
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Frequency adjectives like occasional can occur, unexpectedly, in connection with nouns which do not denote events: Agent Cooper likes an occasional cup of coffee. I provide a full classification of these adjectives and formulate a solution in terms of event semantics which keeps the core semantic contribution of frequency adjectives constant for normal uses and marked uses with non-event nouns. This distinguishes my approach from previous approaches which are merely partial and use non-standard ontologies and semantics for the marked constructions.

description: We calculate perturbatively the energy per nucleon in infinite nuclear matter with a chiral N3LO (next-to-next-to-next-to-leading order) two-body potential plus a N2LO three-body force (3BF). The 3BF low-energy constants which cannot be constrained by two-body observables are chosen such as to reproduce the A=3 binding energies and the triton Gamow-Teller matrix element. This enables to study the nuclear matter equation of state in a parameter-free approach.
