description: Few-layer flakes of hexagonal boron nitride were prepared by ultrasonication of bulk crystals and agglomerated to form thin films. The transmission and reflection spectra of the thin films were measured. The spectral dependences of the linear and circular polarization revealed a hidden anisotropy of the films over the whole sample area which could not be explained by the anisotropy of the chaotically-oriented individual particles. Statistical analysis of optical microscopy images showed a macroscopic particle density distribution with ordering corresponding to the optical axis observed in the polarization data.

description: In software-intensive organizations, an organizational management system will not guarantee organizational success unless the business strategy can be translated into a set of operational software goals. The Goal Question Metric (GQM) approach has proven itself useful in a variety of industrial settings to support quantitative software project management. However, it does not address linking software measurement goals to higher-level goals of the organization in which the software is being developed. This linkage is important, as it helps to justify software measurement efforts and allows measurement data to contribute to higher-level decisions. In this paper, we propose a GQM+Strategies(R) measurement approach that builds on the GQM approach to plan and implement software measurement. GQM+Strategies(R) provides mechanisms for explicitly linking software measurement goals to higher-level goals for the software organization, and further to goals and strategies at the level of the entire business. The proposed method is illustrated in the context of an example application of the method.

Individuals and Predication - A Neurosemantic Perspective

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper we reflect on the constraints that current knowledge and assumptions in the neurosciences impose on theories of concepts and of linguistic meaning. We focus on the operation of predication. A central contention of this paper is that at the neural level there is no fundamental difference between predicate and predicable - representations of individuals and representations of categories are both feature complexes with basically the same structure. We discuss the structure of such representations and the ways in which they interact in certain simple situations of perception and verbal communication.

We confirm that the hadron resonance gas model with the Carnahan-Starling excluded volume effect can reasonably fit the empirical equation of state at high density up to several times the normal nuclear density. We identify the onsets of strange particles and quantify the strangeness contents in dense matter. We finally discuss the finite temperature effects and estimate the thermal index $Γ_{\rm th}$ as a function of the baryon density, which should be a crucial input for the core-collapse supernova and the binary neutron star merger simulations.

description: In Nature 586, 373 (2020), Snider et al announced the experimental discovery of room temperature superconductivity in a carbonaceous sulfur hydride under high pressure, hereafter called CSH. The paper reported sharp drops in the measured magnetic susceptibility as a function of temperature for five different pressures, that were claimed to be a superior test signaling a superconducting transition. Here I present several arguments indicating that the susceptibility data published in that paper were probably fraudulent. This calls into question the validity of the entire paper and its claim of detection of room temperature superconductivity. I also describe the roadblocks that I have encountered in reaching this conclusion. A variety of implications of this situation are discussed.

Metaphorische und metonymische Muster der Adjektiv-Intensivierung
Creators: name: Kirschbaum, Ilja
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In diesem Beitrag soll es um die Frage gehen, welche kognitiven Muster der Adjektiv-Intensivierung im Deutschen zugrunde liegen. Ausgangspunkt ist die These, daß Adjektivphrasen wie höchst zufrieden und furchtbar langsam vor allem durch metaphorische und metonymische Muster motiviert sind. Die metaphorischen Muster können dadurch charakterisiert werden, daß bestimmte Bereiche verschiedener Herkunftsdimensionen auf spezifische Zielskalen übertragen werden, was eine Restrukturierung des spezifischen Skalenbereichs zur Folge hat. Die metonymischen Muster basieren dagegen auf einer indirekten Charakterisierung des Intensitätsgrades als Folge eben dieses Grades. Veranschaulichen läßt sich die metonymische Verschiebung mit Hilfe von Konsekutivsätzen, wobei der Hauptsatz die Ursache und der daß-Komplementsatz die Folge ausdrückt.

description: We investigate the various physical mechanisms that underlie the dynamical instability of a quantized vortex array at the interface between two counter-propagating superflows in a two-dimensional Bose--Einstein condensate. Instabilities of markedly different nature are found to dominate in different flow velocity regimes. For moderate velocities where the two flows are subsonic, the vortex lattice displays a quantized version of the hydrodynamic Kelvin--Helmholtz instability (KHI), with the vortices rolling up and co-rotating. For supersonic flow velocities, the oscillation involved in the KHI can resonantly couple to acoustic excitations propagating away in the bulk fluid on both sides. This makes the KHI rate to be effectively suppressed and other mechanisms to dominate: For finite and relatively small systems along the transverse direction, the instability involves a repeated superradiant scattering of sound waves off the vortex lattice; for transversally unbound systems, a radiative instability dominates, leading to the simultaneous growth of a localized wave along the vortex lattice and of acoustic excitations propagating away in the bulk. Finally, for slow velocities, where the KHI rate is intrinsically slow, another instability associated to the rigid lateral displacement of the vortex lattice due to the vicinity of the system's boundary is found to dominate.

description: Relevant comprehension of flood hazards has emerged as a crucial necessity, especially as the severity and the occurrence of flood events intensify with climate changes. Flood simulation and forecast capability have been greatly improved thanks to advances in data assimilation. This approach combines in-situ gauge measurements with hydrodynamic models, aiming to correct the hydraulic states and reduce the uncertainties in the model parameters, e.g., friction coefficients, inflow discharge. These methods depend strongly on the availability and quality of observations, thus requiring other data sources to improve the flood simulation and forecast quality. Sentinel-1 images collected during a flood event were used to classify an observed scene into dry and wet areas. The study area concerns the Garonne Marmandaise catchment, and focuses on recent flood event in January-February 2021. In this paper, seven experiments are carried out, two in free run modes (FR1 and FR2) and five in data assimilation modes (DA1 to DA5). A model-observation bias was diagnosed and corrected over the beginning of the flood event. Quantitative assessments are carried out involving 1D metrics at Vigicrue observing stations and 2D metrics with respect to the Sentinel-1 derived flood extent maps. They demonstrate improvements on flood extent representation thanks to the data assimilation and bias correction.

Adjectives in Construct
Creators: name: Kim, Ji-Yung
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Hebrew construct-state adjectives (CSAs) show syntactic agreement with an element to which they bear little semantic relation on the surface. I propose that the CSA combines with its complement to form a complex predicate, which behaves like a simplex adjective: the complex predicate semantically modifies and agrees with the noun outside the construct, and the agreement is indicated on the head of this complex predicate, namely the CSA. The one trait that sets CSAs apart from simplex adjectives is that CSAs must be followed by a noun phrase headed by a relational noun (e.g. se’ar ‘hair’ in the example above). I attribute this idiosyncrasy of CSAs to their distinct type, also signaled in their distinct morphology: CSAs are functions seeking relation-type predicates as their arguments. The proposed analysis thus manages to explain all the properties of CSAs while maintaining a maximally straightforward relation between syntax and semantics, and semantics and morphology.

description: How best one can recycle a given quantum resource, mitigating the various difficulties involved in its preparation and preservation, is of considerable importance for ensuring efficient applications in quantum technology. Here we demonstrate quantitatively the resource theoretic advantage of reusing a single copy of a two-qubit entangled state towards information processing. To this end, we consider a scenario of sequential entanglement detection of a given two-qubit state by multiple independent observers on each of the two spatially separated wings. In particular, we consider equal numbers of sequential observers on the two wings. We first determine the upper bound on the number of observers who can detect entanglement employing suitable entanglement witness operators. In terms of the parameters characterizing the entanglement consumed and the robustness of measurements, we then compare the above scenario with the corresponding scenario involving multiple pairs of entangled qubits shared among the two wings. This reveals a clear resource theoretic advantage of recycling a single copy of a two-qubit entangled state in the sequential network.

Tense Selection and the Temporal Interpretation of Complement Clauses
Creators: name: Katz, Graham
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The problem addressed in this paper is tense selection. Clausal complements of verbs such as expect and predict appear to select for finite verbs that are future marked and for infinitival complements that have a future interpretation. It is argued that these two facts can (and must) be given a uniform account. To that end I adopt a relational treatment of tenses and argue for a particular architecture of composition in which the free application of abstraction is component of the grammar. The lexical semantics of future-selecting verbs is argued to contain an implicit future operator and these verbs are taken to select for future relations. The resulting framework is one in which untensed clauses are fundamentally distinguished from tensed clauses, and type-shifting is a regular part of the interpretive process.

description: We revisit the entire framework of group classification of differential equations. After introducing the notion of weakly similar classes of differential equations, we develop the mapping method of group classification for such classes, which generalizes all the versions of this method that have been presented in the literature. The mapping method is applied to group classification of various classes of Kolmogorov equations and of Fokker-Planck equations in the case of space dimension one. The equivalence groupoids and the equivalence groups of these classes are computed. The group classification problems for these classes with respect to the corresponding equivalence groups are reduced to finding all inequivalent solutions of heat equations with inequivalent potentials admitting Lie-symmetry extensions. This reduction allows us to exhaustively solve the group classification problems for the classes of Kolmogorov and Fokker-Planck equations with time-independent coefficients.

Confronting double-detonation sub-Chandrasekhar models with the low-luminosity suppression of Type Ia supernovae

description: Type Ia supernovae (SNe Ia) are likely the thermonuclear explosions of carbon-oxygen (CO) white-dwarf (WD) stars, but their progenitor systems remain elusive. Recently, Sharon & Kushnir (2022) used The Zwicky Transient Facility Bright Transient Survey to construct a synthesized $^{56}$Ni mass, $M_\text{Ni56}$, distribution of SNe Ia. They found that the rate of low-luminosity ($M_\text{Ni56}\approx0.15\,M_{\odot}$) SNe Ia is lower by a factor of $\sim10$ than the more common $M_\text{Ni56}\approx0.7\,M_{\odot}$ events. We here show that in order for the double-detonation model (DDM, in which a propagating thermonuclear detonation wave, TNDW, within a thin helium shell surrounding a sub-Chandrasekhar mass CO core triggers a TNDW within the core) to explain this low-luminosity suppression, the probability of a low-mass ($\approx0.85\,M_{\odot}$) WD explosion should be $\sim100$-fold lower than that of a high-mass ($\approx1.05\,M_{\odot}$) WD. One possible explanation is that the ignition of low-mass CO cores is somehow suppressed. We use accurate one-dimensional numerical simulations to show that if a TNDW is able to propagate within the helium shell, then the ignition within the CO core is guaranteed (resolved here for the first time in a full-star simulation), even for $0.7\,M_{\odot}$ WDs, providing no natural explanation for the low-luminosity suppression. DDM could explain the low-luminosity suppression if the mass distribution of primary WDs in close binaries is dramatically different from the field distribution; if the Helium shell ignition probability is suppressed for low-mass WDs; or if multidimensional perturbations significantly change our results.

description: Optically hyperpolarized $^{129}$Xe gas has become a powerful contrast agent in nuclear magnetic resonance (NMR) spectroscopy and imaging, with applications ranging from studies of the human lung to the targeted detection of biomolecules. Equally attractive is its potential use to enhance the sensitivity of microfluidic NMR experiments, in which small sample volumes yield poor sensitivity. Unfortunately, most $^{129}$Xe polarization systems are large and non-portable. Here we present a microfabricated chip that optically polarizes $^{129}$Xe gas. We have achieved $^{129}$Xe polarizations greater than 0.5$\%$ at flow rates of several microliters per second, compatible with typical microfluidic applications. We employ in situ optical magnetometry to sensitively detect and characterize the $^{129}$Xe polarization at magnetic fields of 1 $μ$T. We construct the device using standard microfabrication techniques, which will facilitate its integration with existing microfluidic platforms. This device may enable the implementation of highly sensitive $^{129}$Xe NMR in compact, low-cost, portable devices.
Systematic Task Allocation Evaluation in Distributed Software Development

description: Systematic task allocation to different development sites in global software de- velopment projects can open business and engineering perspectives and help to reduce risks and problems inherent in distributed development. Relying only on a single evaluation criterion such as development cost when distributing tasks to development sites has shown to be very risky and often does not lead to successful solutions in the long run. Task allocation in global software projects is challenging due to a multitude of impact factors and constraints. Systematic allocation decisions require the ability to evaluate and compare task allocation alternatives and to effectively establish customized task allocation practices in an organization. In this article, we present a customizable process for task allocation evaluation that is based on results from a systematic interview study with practitioners. In this process, the relevant criteria for evaluating task allocation alternatives are derived by applying principles from goal-oriented measurement. In addition, the customization of the process is demonstrated, related work and limitations are sketched, and an outlook on future work is given.

Agentive selbst in German
Creators: name: Hole, Daniel
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper deals with the syntax and semantics of the German adverbial intensifying particle selbst/selber as in Paul hat seine Wäsche selbst gewaschen ‘Paul has done his washing himself.’ I will claim that selbst denotes the identity function, and that it takes the agentive Voice head proposed by Kratzer (1996) as its semantic argument. This minimal semantics will be combined with standard assumptions about information structure to derive the specific contextual restrictions encountered with adverbial intensifiers. Section 1 prepares the ground for this analysis by presenting a similar account of adnominal intensifiers as in Paul selbst hat seine Wäsche gewaschen ‘Paul himself has done his washing’. The discussion of adnominal intensifiers adopts basic insights arrived at by Moravcsik (1972), König (1991), Siemund (2000a) and Eckardt (2000). Section 2 constitutes the main body of the paper. First some effort is made to tell apart adnominal from adverbial uses of intensifiers by using criteria that do not just rely on (surface) position. I will oppose Eckardt’s position that most adverbial intensifiers are interpreted like adnominal intensifiers; moreover I will note a close link between adverbial intensifiers and agentivity which justifies dubbing adverbial intensifiers “agentive intensifiers” (section 2.1). Tasks to be dealt with in the following are identified in section 2.2, at the same time previous proposals and categorizations are reviewed. Section 2.3 introduces the analysis in terms of Voice.

Relative Specificity
Creators: name: Von Heusinger, Klaus
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Semantic theories of specificity are based on the assumptions that a specific indefinite has wide scope and/or a referential reading. However, there are specific indefinites that are neither wide scope expressions nor referential expressions. I call this kind of specificity “relative specificy” and take it as the most general case of specific indefinites. I propose that indefinite NPs have a referential index, like modal or temporal indices. This index can be anchored to another expression in the discourse. If the index is anchored to another referential expression, the indefinite receives a specific reading.

description: In this work we study the effect of density dependent nonlinear diffusion on pattern formation in the Lengyel--Epstein system. Via the linear stability analysis we determine both the Turing and the Hopf instability boundaries and we show how nonlinear diffusion intensifies the tendency to pattern formation; %favors the mechanism of pattern formation with respect to the classical linear diffusion case; in particular, unlike the case of classical linear diffusion, the Turing instability can occur even when diffusion of the inhibitor is significantly slower than activator's one. In the Turing pattern region we perform the WNL multiple scales analysis to derive the equations for the amplitude of the stationary pattern, both in the supercritical and in the subcritical case. Moreover, we compute the complex Ginzburg-Landau equation in the vicinity of the Hopf bifurcation point as it gives a slow spatio-temporal modulation of the phase and amplitude of the homogeneous oscillatory solution.

The use of Multilayered Extended Semantic Networks for Meaning Representation
Creators: name: Helbig, Hermann
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The framework of Multilayered Extended Semantic Networks (abbreviated: MultiNet) is one of the few knowledge representation paradigms along the line of Semantic Networks (abbreviated: SN) having a comprehensive, systematic, and publicly available documentation. The paper describes the main features of MultiNet and the standard repertoire of representational means provided by this system, the application of MultiNet for the meaning representation of natural language expressions, and the software tools connected with it. Besides of the structural information, which is manifested in the relational and functional connections between nodes of the SN, the conceptual representatives of MultiNet are characterized by embedding the nodes of the network into a multidimensional space of layer attributes. To warrant cognitive adequacy and universality of the knowledge representation, every node of the SN uniquely represents a concept, while the relations between them have to be expressed by a predefined set of about 110 semantic primitive relations and functions, which are described on a metalevel by means of an axiomatic system of second order predicate calculus formulae. The classification of MultiNet nodes into sorts (which form a conceptual ontology) is an important basis for the definition of the domains and value restrictions of the above-mentioned relations and functions. To support the effective work with MultiNet and to deal with the semantic phenomena of natural language, MultiNet has been provided with several software tools, which include: MWR: A workbench for the knowledge engineer supporting the graphical representation and manipulation of MultiNet networks as well as the accumulation and management of MultiNet knowledge bases. NatLink: An interpreter which automatically translates natural language sentences into MultiNet semantic networks by means of a word-class controlled syntactic-semantic analysis. LIA: An interactive workbench for the computer lexicographer which is used to create large semantically oriented computer lexica based on the expressional means of MultiNet. All three tools are important prerequisites for the use of MultiNet as a semantic interlingua in NLP systems.

description: We report the effects of variation in length on the electronic structure of CdSe nanorods derived from atomic clusters and passivated by fictitious hydrogen atoms. These nanorods are augmented by attaching gold clusters at both the ends to form a nanodumbbell. The goal is to assess the changes at nanolevel after formation of contacts with gold clusters serving as electrodes and compare the results with experimental observations [PRL, 95, 056805 (2005)]. Calculations involving nanorods of length 4.6 Angstrom to 116.6 Angstrom are performed using density functional theory implemented within plane-wave basis set. The binding energy per atom saturates for nanorod of length 116.6 Angstrom. It is interesting to note that upon attaching gold clusters, the nanorods shorter than 27 Angstrom develop metallicity by means of metal induced gap states (MIGS). Longer nanorods exhibit a nanoscale Schottky barrier emerging at the center. For these nanorods, interfacial region closest to the gold electrodes shows a finite density of states in the gap due to MIGS, which gradually decreases towards the center of the nanorod opening up a finite gap. Bader charge analysis indicates localized charge transfer from metal to semiconductor.

description: Supergravity embedding of the Standard Model of particle physics provides phenomenologically well-motivated and observationally viable inflationary scenarios. We investigate a class of inflationary models based on the superconformal framework of supergravity and discuss constraints from the reheating temperature, with the particular focus on the gravitino problem inherent in these scenarios. We point out that a large part of the parameter space within the latest BICEP/Keck 95\% confidence contour may have been excluded by the gravitino constraints, depending on the mass scale of the inflaton. Precision measurements of the scalar spectral index by a future mission may rule out some of these scenarios conclusively.

In this work, we present a comprehensive model of the performance of a free-space ground-to-ground quantum key distribution (QKD) system based on the efficient-BB84 protocol with active decoy states. Our model takes into account the atmospheric channel contribution, the transmitter and receiver telescope design constraints, the parameters of the quantum source and detectors, and the finite-key analysis to produce a set of requirements and optimal design choices for a QKD system operating under specific channel conditions. The channel attenuation is calculated considering all effects deriving from the atmospheric propagation (absorption, beam broadening, beam wandering, scintillation, and wavefront distortions), as well as the effect of fiber-coupling in the presence of a partial adaptive correction with finite control bandwidth. We find that the channel fluctuation statistics must be considered to correctly estimate the effect of the saturation rate of the single-photon detectors, which may otherwise lead to an overestimation of the secret key rate. We further present strategies to minimize the impact of diffuse atmospheric background in daylight operation by means of spectral and temporal filtering.

Ellipsis and the Structure of Discourse
Creators: name: Hardt, Daniel
name: Romero, Maribel
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Many authors have suggested that ellipsis and other processes of reduction require a certain similarity or parallelism between the reduced clause and some antecedent clause in discourse. We claim that discourse structure constrains the way in which ellipsis satisfies a parallelism constraint: the parallelism match must involve two clauses that are related by local c-command in the discourse tree.

Verbs In Conceptual Space
Creators: name: Geuder, Wilhelm
name: Weisgerber, Matthias
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In his book ‘Conceptual Spaces’ Ga¨rdenfors (2000) sets out a framework for the representation of concepts and word meanings which defines semantic features as values on ordered property scales and arranges these scales as independent quality dimensions in a multidimensional coordinate system. The resulting representation of a concept is therefore a region in “conceptual space”. In this paper, we will briefly introduce this model, and then explore possible ways of adapting it to verb meanings.

Semantic Change in Grammaticalization
Creators: name: Eckardt, Regine
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper, I want to establish semantic reanalysis as an independent mode of meaning change in language history. My point of departure will be cases of language change that have traditionally been classed as „grammaticalization“, on one hand because we will find very nice instances of semantic reanalysis particuarly in that field, and on the other hand because I think that the notion of semantic reanalysis that I propose can be particularly helpful in elucidating some hitherto poorly understood semantic changes in grammaticalization. In order to achive this double purpose, to characterise semantic reanalysis and to demonstrate its power as a tool of diachronic analysis, the paper is organized in the following way: I will first briefly present some cases of grammaticalization, focussing mainly on the meaning changes they involve. I will next give an overview over previous proposals as to what kind of semantic processes underlie these changes, arguing that neither of them is fully convincing. I will then demonstrate how the meaning side of the changes in question can be analysed as semantic reanalysis in semantic composition. Finally, I will evaluate the emerging picture with respect to the common observation that the meanings of words in grammaticalization just „fade away“ or „bleach“.

description: We search for variations in the disk of Centaurus A of the emission from atomic fine structure lines using Herschel PACS and SPIRE spectroscopy. In particular we observe the [C II](158 $μ$m), [N II](122 and 205 $μ$m), [O I](63 and 145 $μ$m) and [O III](88 $μ$m) lines, which all play an important role in cooling the gas in photo-ionized and photodissociation regions. We determine that the ([C II]+[O I]$_{63}$)/$F_{TIR}$ line ratio, a proxy for the heating efficiency of the gas, shows no significant radial trend across the observed region, in contrast to observations of other nearby galaxies. We determine that 10 - 20% of the observed [C II] emission originates in ionized gas. Comparison between our observations and a PDR model shows that the strength of the far-ultraviolet radiation field, $G_0$, varies between $10^{1.75}$ and $10^{2.75}$ and the hydrogen nucleus density varies between $10^{2.75}$ and $10^{3.75}$ cm$^{-3}$, with no significant radial trend in either property. In the context of the emission line properties of the grand-design spiral galaxy M51 and the elliptical galaxy NGC 4125, the gas in Cen A appears more characteristic of that in typical disk galaxies rather than elliptical galaxies.

Zu einer semantischen Klassifikation der intransitiven haben - und sein - Verben im Deutschen
Creators: name: Diedrichsen, Elke
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Die Literatur hat gezeigt, dass die syntaktischen Kriterien der Unakkusativ-/Unergativ-Distinktion durch semantische Kriterien zumindest unterstützt, wenn nicht gar ersetzt werden können. In diesem Beitrag werde ich mich auf eines der Unakkusativitätskriterien, die Auxiliarselektion, konzentrieren. Es soll gezeigt werden, dass die Wahl von haben- und sein- Perfekt bei intransitiven Verben im Deutschen semantisch zu motivieren ist. Fasst man das haben- Perfekt als Defaultfall auf, so lassen sich für die Wahl des sein-Perfekts spezifische semantische Kriterien aufstellen, die anhand von Beispielen vorgestellt und erläutert werden sollen. Die Kriterien können zu einem übergreifenden Basiskriterium zusammengefasst werden, das auch solche Fälle von sein-Perfekt einschließt, die für eine semantische Klassifikation bisher als problematisch angesehen worden sind.

description: In the ferromagnetic Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. We use external pressure as an effective tuning parameter and relate three observations to the presence of a nontrivial topology in its ferromagnetic regime: an exceptional temperature response of the quantum oscillations amplitude, the presence of an anomalous Hall effect (AHE), and the existence of an unusual loop Hall effect (LHE). We find a suppression of the AHE and the LHE with increasing pressure, while the Curie temperature is enhanced. The magnetic structure and the electronic bands exhibit only a negligible pressure effect suggesting the importance of the domain wall landscape for the topological behavior in CeAlSi.
Outbreak statistics and scaling laws for externally driven epidemics

description: Power-law scalings are ubiquitous to physical phenomena undergoing a continuous phase transition. The classic Susceptible-Infectious-Recovered (SIR) model of epidemics is one such example where the scaling behavior near a critical point has been studied extensively. In this system the distribution of outbreak sizes scales as $P(n) \sim n^{-3/2}$ at the critical point as the system size $N$ becomes infinite. The finite-size scaling laws for the outbreak size and duration are also well understood and characterized. In this work, we report scaling laws for a model with SIR structure coupled with a constant force of infection per susceptible, akin to a `reservoir forcing'. We find that the statistics of outbreaks in this system are fundamentally different than those in a simple SIR model. Instead of fixed exponents, all scaling laws exhibit tunable exponents parameterized by the dimensionless rate of external forcing. As the external driving rate approaches a critical value, the scale of the average outbreak size converges to that of the maximal size, and above the critical point, the scaling laws bifurcate into two regimes. Whereas a simple SIR process can only exhibit outbreaks of size $\mathcal{O}(N^{1/3})$ and $\mathcal{O}(N)$ depending on whether the system is at or above the epidemic threshold, a driven SIR process can exhibit a richer spectrum of outbreak sizes that scale as $O(N^ξ)$ where $ξ\in (0,1] \backslash \{2/3\}$ and $\mathcal{O}((N/\log N)^{2/3})$ at the multi-critical point.

I give an alternative proof of his result which generalizes to type ⟨n⟩ quantifiers, and I show how the reduction of a reducible type ⟨n⟩ quantifier to (the composition of) n type ⟨1⟩ quantifiers can be effectuated.

Non-dynamic Analyses of Anaphoric Pronouns: Do things look better in 2-D?
Creators: name: Breheny, Richard
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper compares pragmatic accounts of anaphoric relations between indefinites and pronouns. We argue that Stalnaker’s (1998) account which exploits features of his two dimensional framework for representing context and content is too weak. We suggest that the definiteness of anaphoric pronouns can be captured only if we consider them E-type.

Performance Analysis and Optimization for Interference Alignment over MIMO Interference Channels with Limited Feedback

description: In this paper, we address the problem of interference alignment (IA) over MIMO interference channels with limited channel state information (CSI) feedback based on quantization codebooks. Due to limited feedback and hence imperfect IA, there are residual interferences across different links and different data streams. As a result, the performance of IA is greatly related to the CSI accuracy (namely number of feedback bits) and the number of data streams (namely transmission mode). In order to improve the performance of IA, it makes sense to optimize the system parameters according to the channel conditions. Motivated by this, we first give a quantitative performance analysis for IA under limited feedback, and derive a closed-form expression for the average transmission rate in terms of feedback bits and transmission mode. By maximizing the average transmission rate, we obtain an adaptive feedback allocation scheme, as well as a dynamic mode selection scheme. Furthermore, through asymptotic analysis, we obtain several clear insights on the system performance, and provide some guidelines on the system design. Finally, simulation results validate our theoretical claims, and show that obvious performance gain can be obtained by adjusting feedback bits dynamically or selecting transmission mode adaptively.
