description: This paper introduces the notions of vector field and flow on a general differentiable stack. Our main theorem states that the flow of a vector field on a compact proper differentiable stack exists and is unique up to a uniquely determined 2-cell. This extends the usual result on the existence and uniqueness of flows on a manifold as well as the author's existing results for orbifolds. It sets the scene for a discussion of Morse Theory on a general proper stack and also paves the way for the categorification of other key aspects of differential geometry such as the tangent bundle and the Lie algebra of vector fields.

Alternating conj/disjunctions: the case of Japanese "-toka" and "-tari"
Creators: name: Smith, Ryan Walter
name: Kobayashi, Ryoichiro
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: This paper investigates the interpretation of Japanese -toka and -tari, two nonexhaustive particles that receive conjunctive interpretations in upward-entailing environments, but disjunctive interpretations in downward-entailing and question contexts. We analyze -toka and -tari as items that introduce unstructured sets of alternatives in a Hamblin-style alternative semantics (Hamblin, 1973; Kratzer and Shimoyama, 2002), and derive their conjunctive and disjunctive readings via an interaction between these sets and the semantics of the environment containing them. Keywords: -toka, -tari, Japanese, alternative semantics, conjunction, disjunction

Ever free relatives crosslinguistically
Creators: name: Šimík, Radek
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: Based on a sample of seven languages, I show that the so-called modal inferences in ever free relatives (ignorance and indifference) are not universally available. The primary reading of ever free relatives crosslinguistically turns out to be a “non-modal” one, which is available to all languages under investigation. The implication is that if there is a modal inference triggered by the use of the ever-morpheme in FRs, the inference is likely to have a source external to the ever free relative (Lauer, 2009; Condoravdi, 2015; Hirsch, 2016). In line with this conclusion, I propose to generalize Hirsch’s (2016) analysis of ignorance ever free relatives, suggesting that all ever free relatives, no matter how they are ultimately interpreted, are instances of (un)conditionals + donkey-anaphoric definite descriptions. Keywords: ever free relatives, (un)conditionals, definite descriptions,modal inferences, crosslinguistic semantics

description: The non-repudiation as an essential requirement of many applications can be provided by the asymmetric key model. With the evolution of new applications such as mobile commerce, it is essential to provide secure and efficient solutions for the mobile environments. The traditional public key cryptography involves huge computational costs and is not so suitable for the resource-constrained platforms. The elliptic curve-based approaches as the newer solutions require certain considerations that are not taken into account in the traditional public key infrastructures. The main contribution of this paper is to introduce a Lightweight Public Key Infrastructure (LPKI) for the constrained platforms such as mobile phones. It takes advantages of elliptic curve cryptography and signcryption to decrease the computational costs and communication overheads, and adapting to the constraints. All the computational costs of required validations can be eliminated from end-entities by introduction of a validation authority to the introduced infrastructure and delegating validations to such a component. LPKI is so suitable for mobile environments and for applications such as mobile commerce where the security is the great concern.

Decomposing universal projection in questions

Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: Revising a proposal by Guerzoni (2003), we propose to derive universal projection of presuppositions in wh-questions, where attested, from a family of three felicity conditions on question use. Assuming that these felicity conditions can be violated under certain conditions, this proposal predicts a typology of contexts where universal projection can exceptionally be unattested. We propose that this prediction is correct, presenting a family of scenarios where the expected absence of universal projection is observed. Keywords: wh-questions, universal presupposition projection, felicity conditions, bridge principles.

similarity approach strikes back: Negation in counterfactuals
Creators: name: Schulz, Katrin
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: The meaning of counterfactual conditionals is standardly described using the similarity approach (Stalnaker, 1968; Lewis, 1973). This approach has recently been challenged by Ciardelli et al. (2018). They argue that the similarity approach is in principle unable to account for the meaning of counterfactuals with an antecedent consisting of a conjunction embedded under a negation (¬(p^q)). Ciardelli et al. (2018) dismiss the approach on these grounds and offer an alternative. The main goal of the present paper is to defend the similarity approach against this attack. I will argue that the problem that underlies the observations in Ciardelli et al. 2018 is more general and not solved by the solution they offer. I will furthermore argue, against Ciardelli et al. (2018), that the cause of the problem is not the similarity approach, but the interaction of negation with the meaning of counterfactual conditionals. The paper will conclude with a first outline of a solution for the problem, which still uses the similarity approach, but combines it with an alternative semantics for negation. Keywords: counterfactuals, negation, similarity approach, causality.

Some factors affecting the extraction of sulphate from selected Lower Fraser Valley and Vancouver Island soils
Creators: name: Bart, Aldwyn Louis
Publisher: name: University of British Columbia
Year: 2012

description: A study was undertaken to determine some of the factors which affected the extraction of sulphur from seven selected soils of the Lower Fraser Valley and Vancouver Island; with particular reference to the effect of pH, concentration and cation of phosphate buffers. In all cases the presence of phosphate resulted in more sulphur being extracted, than extraction with water only. In every instance increasing the concentration of neutral sodium phosphate buffers from 0.005M to 0.5M resulted in increasing sulphur extraction. Using a 0.5H sodium phosphate buffer and increasing the pH from 4 to 8 generally resulted in maximum extraction at pH 7, except notably in the Langford soil in which the amount of sulphur extracted increased as the pH was changed from 4 to 8. The behaviour of four surface soils when extracted with 0.5M sodium phosphate at varying pH levels was quite similar, the mineralogy of the <2µ fraction was also similar. Gel filtration studies of the 0.5M phosphate extracts of the Langford showed that at pH 4 little inorganic sulphate was extracted, while from pH 6 to 8, the amount extracted remained almost constant, though more than three times that extracted at pH 4. The extracted organic fraction increased as the pH varied from 4 to 8. In soils with a low carbon content and a high content of free iron and aluminum oxides, the water extractable sulphur was very low, as was the amount of phosphate extractable organic sulphate. The amount of sulphate extracted from the original air dry samples by 0.5M phosphate was very much less than the sulphate adsorbed from a 50 ppm sulphur solution. It was found that a neutral 0.5M sodium phosphate solution extracted more sulphur in nearly all cases, than other extractants, and in the soils studied cold water did not seem suitable. The neutral 0.5M phosphate solution extracted inorganic and a portion of the organic sulphate and may be expected to be a suitable chemical extractant which will be able to indicate the sulphur status of soils of the Lower Fraser Valley.

The resonance amplitude associated with the Gamow states

description: The Gamow states describe the quasinormal modes of quantum systems. It is shown that the resonance amplitude associated with the Gamow states is given by the complex delta function. It is also shown that under the near-resonance approximation of neglecting the lower bound of the energy, such resonance amplitude becomes the Breit-Wigner amplitude. This result establishes the precise connection between the Gamow states, Nakanishi's complex delta function and the Breit-Wigner amplitude. In addition, this result provides another theoretical basis for the phenomenological fact that the almost-Lorentzian peaks in cross sections are produced by intermediate, unstable particles.

description: We present a theoretical investigation of the excitation of multiple electrostatic wakefields by the ponderomotive force of a short electromagnetic pulse propagating through a dense plasma. It is found that the inclusion of the quantum statistical pressure and quantum electron tunneling effects can qualitatively change the classical behavior of the wakefield. In addition to the well known plasma oscillation wakefield, with a wavelength of the order of the electron skin depth, which in a dense plasma is of the order of several nanometers, wakefields in dense plasmas with a shorter wavelength are also excited. The wakefields can trap electrons and accelerate them to extremely high energies over nanoscales.

pa/wa of imperative alternatives
Creators: name: Saito, Hiroaki

Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: This paper deals with topic markers interacting with discourse information in imperatives. It compares two topic markers from Slovenian (‘pa’) and Japanese (‘-wa’) and shows that while they mostly match in terms of the foci they associate with, their functions differ in imperatives: only ‘pa’ may yield a concessive imperative reading. It is shown that this reading can be derived while keeping a single entry for ‘pa’ by making attitudes of discourse participants part of the focus ‘pa’ associates with. The split between Slovenian and Japanese can then be attributed to minor differences in terms of which foci ‘pa’ and ‘-wa’ may associate with. Keywords: imperatives, Slovenian, Japanese, alternative semantics, topic markers, focus, discourse particles, performative modality.

semantics of Turkish numeral constructions
Creators: name: Sağ, Yağmur
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: This paper explores Turkish numeral constructions, which have typologically two interesting properties: (i) the existence of an optional classifier, (ii) the incompatibility of plurals with them. I argue that numerals are modifiers of type <,> defined only for atomic properties (Ionin and Matushansky 2006). The explanation rests on the semantics of bare singulars proposed to denote sets of atoms (contra Bale et al. 2010), and the semantics of the classifier claimed to be a partial identity function presupposing atomic properties. Keywords: numerals, atomicity, number neutrality, plurality, kinds, optional classifiers.

Communicating Expert Opinion: What Do Forensic Scientists Say and What Do Police, Lawyers, and Judges Hear?
Creators: name: Howes, Loene
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Police administration, procedures and practice

description: Forensic scientists’ expert opinions are used increasingly in the course of police investigations, out-of-court settlements, and trials. For an expert opinion to benefit the community, it must be understood adequately by those charged with using it as a decision-aid. This project aimed to explore the effectiveness of communication about forensic science to police, lawyers, and judges in Australian jurisdictions. Three studies explored the readability of international expert conclusions and Australian expert reports. Content analyses of expert reports of forensic comparison of glass and DNA demonstrated that reports were typically written at a level suited to other experts. The results of these studies were then considered in light of the development of national and international standards for reporting. Based on the studies and analysis of reporting standards, practical recommendations were made to enhance the readability of expert reports, without compromising scientific integrity. Two subsequent studies explored practitioners’ experiences of the communication of expert opinion. Police investigators, legal practitioners and forensic scientists participated in semi-structured interviews. Thematic analyses highlighted the value of cross-disciplinary interaction and discussion, not only to foster understanding of expert opinion, but also to assist experts in developing their explanations. Recommendations were made to build on strengths in the communication between forensic scientists and police and legal practitioners within their professional contexts. It is hoped that the recommendations from this project can contribute to increased effectiveness in the communication of forensic science, and therefore to the trustworthiness and integrity of the criminal justice system. Further research, using a case-study approach, could examine the initiatives undertaken to enhance the communication of forensic science in the nuanced contexts of particular jurisdictions.
Presuppositional implicatures: quantity or maximize presupposition?
Creators: name: Rouillard, Vincent

Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: Schlenker (2012) proposes that when framed within a modern Stalnakerian view of presupposition and common ground (Stalnaker, 1998, 2002), Maximize Presupposition! (Heim, 1991; Sauerland, 2008) can be viewed as a special case of the maxim of Quantity (Grice, 1975). We provide data suggesting that in some cases, Maximize Presupposition! applies even when speakers are not expected to use a presupposition as vectors of new information. We argue that these data support the view that Maximize Presupposition! is an independent pragmatic principle, distinct from Quantity. Keywords: maximize presupposition, quantity, presuppositional implicatures, scalar implicatures.

description: We consider some possible phenomenological implications of the extended uncertainty principle, which is believed to hold for quantum mechanics in de Sitter spacetime. The relative size of the corrections to the standard results is however of the order of the ratio between the length scale of the quantum mechanical system and the de Sitter radius, and therefore exceedingly small. Nevertheless, the existence of effects due to the large scale curvature of spacetime in atomic experiments has a theoretical relevance.

description: Excerpts from the report: The primary objective of this report is to assist research workers by directing their attention to areas in agricultural cooperation where research is needed. Individual projects within each problem area may then be developed on the basis of the need and interest in the project on the part of interested cooperatives and the research institution, time and funds available, capacity of the research worker, and other pertinent considerations. It is hoped that this preliminary outline will stimulate research. The Cooperative Research and Service Division and the American Institute of Cooperation believe this publication, even in its present form, will assist workers to select and develop projects of basic value to agricultural producers and their cooperatives. Many of the problems of cooperatives are similar to those of other firms, and they may be solved similarly. However, many problems of cooperatives are different from those of other agencies. This manual sets forth distinctive areas of research in cooperative buying and selling together with examples of project statements.

Since this Division in December 1953 became the Farmer Cooperative Service, U. S. Department of Agriculture, we are now reissuing it as a publication of Farmer Cooperative Service.
Responsive predicates are question-embedding: evidence from Estonian
Creators: name: Roberts, Tom
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: The proper semantic treatment of the complements of Responsive Predicates (ResPs), those predicates which may embed either declarative or interrogative clauses, is a longstanding puzzle, given standard assumptions about complement selection. In order to avoid positing systematic polysemy for ResPs, typical treatments of ResP complements treat their arguments either as uniformly declarative-like (propositional) or interrogative-like (question). I shed new light on this question with novel data from Estonian, in which there are verbs think-like meanings with declarative complements and wonder-like meanings with interrogative complements. I argue that these verbs’ meaning is fundamentally incompatible with a proposition-taking semantics for ResPs, and therefore a question-taking semantics is to be preferred. Keywords: responsive predicates, embedded clauses, interrogatives, contemplation, Estonian.

Nucleosynthesis of 56Ni in wind-driven Supernova Explosions and Constraints on the Central Engine of Gamma-Ray Bursts

description: Theoretically expected natures of a supernova driven by a wind/jet are discussed. Approximate analytical formulations are derived to clarify basic physical processes involved in the wind/jet-driven explosions, and it is shown that the explosion properties are characterized by the energy injection rate (Edot_iso) and the mass injection rate (Mdot_iso). To explain observations of SN 1998bw associated with Gamma-Ray Burst (GRB) 980425, the following conditions are required: Edot_iso Mdot_iso > ~ 10^{51} erg M_sun s^{-2} and Edot_iso > ~ 2 x 10^{52} erg s^{-1} (if the wind Lorentz factor Gamma_w ~ 1) or Edot_iso > ~ 7 x 10^{52} erg s^{-1} (if Gamma_w >> 1). In SN 1998bw, 56Ni (~ 0.4M_sun) is probably produced in the shocked stellar mantle, not in the wind. The expected natures of SNe, e.g., ejected 56Ni masses and ejecta masses, vary depending on Edot_iso and Mdot_iso. The sequence of the SN properties from high Edot_iso and Mdot_iso to low Edot_iso and Mdot_iso is the following: SN 1998bw-like -- intermediate case -- low mass ejecta (< ~ 1M_sun$) where 56Ni is from the wind -- whole collapse. This diversity may explain the diversity of supernovae associated with GRBs. Our result can be used to constrain natures of the wind/jet, which is linked to the central engine of GRBs, by studying properties of the associated supernovae.

description: This paper presents the results of two experiments in German testing the acceptability of (non-)restrictive relative clauses (NRCs/RRCs) with split antecedents (SpAs). According to Moltmann (1992), SpAs are only grammatical if their parts occur within the conjuncts of a coordinate structure and if they have identical grammatical functions. Non-conjoined SpAs that form the subject and the object of a transitive verb are predicted to be ungrammatical. Our study shows that the acceptability of such examples improves significantly if the predicate that relates the parts of the SpA is symmetric. Moreover, it suggests that NRCs and RRCs behave differently in these cases with respect to the SpA-construal. We can make sense of this observation if we follow Winter (2016) in assuming that transitive symmetric predicates have to be analyzed as unary collective predicates and thus provide a collective antecedent for the RC at the semantic (not the syntactic) level. As we will argue, this accounts for some of the disagreement we found in the literature and gives us new insights into both the semantics of symmetric predicates and the semantics of NRCs. Keywords: non-restrictive relative clause, restrictive relative clause, symmetric predicate, split antecedent.

description: This upload contains all the python codes used in the paper titled "Phenomenological Dark Energy model with hybrid dynamic Cosmological Constant" [1] in pdfLaTeX format. There are five codes in the upload overall. A short description of what the codes do is given below – The code files named “Standard model test code” and “Hubble diagram code” fit supernova data from Union 2.1 collaboration [2] to the standard ΛCDM model and hybrid dynamic Cosmological Constant model (the model of the concerned paper) for estimating the relevant model parameters for flat Universe. The fitting procedure uses emcee [3] within the Lmfit module [4] of python which implements the Affine Invariant Markov Chain Monte Carlo (MCMC) method for extracting the model parameters. Publicly available Union 2.1 data has been presented in a .txt file named “union 2.1 sorted” for convenience and the codes are written to read data directly from the .txt file. (The tab-separated columns of union 2.1 sorted.txt stands for Redshift, Distance Modulus, and Distance Modulus Error respectively of union 2.1 Supernova data). The code files “Scale factor evolution code” and “Deceleration parameter evolution code” plot the evolution of scale factor and deceleration parameter for both – standard ΛCDM model and hybrid dynamic Cosmological Constant model using the fitted values of parameters. The code file “Derived Parameters code” calculates the derived Cosmological parameters - present-day deceleration parameter, transition redshift, and Age of the Universe for standard ΛCDM model and hybrid dynamic Cosmological Constant model. Parts of the code that calculates Cosmic Age has been adapted from Fatima et al. [5]
description: The manuscript related to the codes has been accepted and is currently available online at https://doi.org/10.1088/1361-6382/ac35ed A new version of the codes will be uploaded soon which will include new codes used in the paper due to revision during the peer-review process.

description: We consider the use of single-photon counting detectors in coherence-domain imaging. Detectors operated in this mode exhibit reduced noise, which leads to increased sensitivity for weak light sources and weakly reflecting samples. In particular, we experimentally demonstrate the possibility of using superconducting single-photon detectors (SSPDs) for optical coherence-domain reflectometry (OCDR). These detectors are sensitive over the full spectral range that is useful for carrying out such imaging in biological samples. With counting rates as high as 100 MHz, SSPDs also offer a high rate of data acquisition if the light flux is sufficient.

subject: FOS: Physical sciences

description: In this paper we present a framework which provides an analytical (i.e., infinitely differentiable) transformation between spatial coordinates and orbital elements for the solution of the gravitational two-body problem. The formalism omits all singular variables which otherwise would yield discontinuities. This method is based on two simple real functions for which the derivative rules are only required to be known, all other applications -- e.g., calculating the orbital velocities, obtaining the partial derivatives of radial velocity curves with respect to the orbital elements -- are thereafter straightforward. As it is shown, the presented formalism can be applied to find optimal instants for radial velocity measurements in transiting exoplanetary systems to constrain the orbital eccentricity as well as to detect secular variations in the eccentricity or in the longitude of periastron.

Embedding non-restrictive relative clauses

description: Schlenker (2010) recently provided data from English and French suggesting that, contrary to standard assumptions (McCawley, 1982; Potts, 2005; Arnold, 2007; AnderBois et al., 2011), non-restrictive relative clauses (NRCs) can take narrow scope under operators of the sentence within which they are embedded. This paper presents three experiments in German confirming this claim. The results show that embedded readings are available with NRCs in German and give first insights into the puzzle under which conditions these embedded readings do or do not show up. Keywords: relative clauses, appositives, projection, rhetorical relations.

Constraining (shifting) types at the interface
Creators: name: Poole, Ethan
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: This paper argues that traces only range over individual semantic types and cannot be type shifted into higher types to circumvent this restriction. The evidence comes from movement targeting positions where DPs must denote properties and the behavior of definite descriptions in these positions. These constraints on possible traces demonstrate that syntactic operations impose active restrictions on permissible semantic types in natural language. Keywords: semantic types, traces, movement, reconstruction, type shifting, properties.

Starting from the theories presented by symbolic anthropology and intercultural communication, the author proposes a model for a ritual communication of the faith; one that responds to the challenge of a type of communication in the Church that is more participatory and multiethnic in character.
Decay following pruning of Balsam fir in the Maritime Provinces of Canada

description: As management of forests and parks intensifies, pruning of conifers becomes more common. Thus understanding the role of wounds as possible entry courts for decay fungi is vital. In order to study some aspects of this, three natural stands, one in New Brunswick and two in Nova Scotia, which had been pruned 4 to 7 years earlier by industrial or displaced workers, were examined. Five pruned and two unpruned balsam fir (Abies balsamea (L.) Mill.) trees from each stand were dissected; cultural isolations were taken from 207 knots where pruning had caused little or no apparent damage to the bole, and from 169 blazes resulting from less careful prunings. All 15 pruned trees, ranging in age from 23 to 42 years, had decay attributable to pruning which averaged 1.7% of the stem volume. This incidence and volume of decay exceeds that recorded in unpruned trees 40 to 60 years old in New Brunswick. Axe blazes were the major entry court for decay-causing fungis basidiomycetes were associated with 12% of the blazes and with 5% of the more carefully pruned knots. Neither stem nor butt decay was found in the unpruned trees. In a further study, 7 branches on each of 30 balsam fir trees near Fredericton, N. B. were experimentally axe pruned; some carefully, some carelessly; both during tree dormancy and during wet and dry periods of active growth. Thirty additional branches were saw pruned. At periods of 2 to 3 weeks, 5 to 7 months and 17 to 19 months after pruning, cultures were made in the field from 70 of the pruning wounds. Within 2 weeks of the latter period, the trees were dissected, measured and further cultures were made in the laboratory from the same 70 wounds. Eighteen months after pruning, 28 of 30 trees had decay averaging 3.9% of stem volume and basidiomycetes were isolated from 22 (31%) of 70 wounds. In the controls butt decay only occurred in 4 of 10 trees. These studies show: (l) that blazes into sapwood (careless pruning) were more frequently infected than those where little or no sapwood was exposed; (2) the incidence of infection was least in branches pruned during the dry period and about equal for those pruned in the wet-active and dormant periods; and (3) the successional pattern began with imperfect fungi and bacteria, and terminated with decay fungi.

description: The GSM network with the greatest worldwide number of users, succumbs to several security vulnerabilities. The short message service (SMS) is one of its superior and well-tried services with a global availability in the GSM networks. The main contribution of this paper is to introduce a new secure application layer protocol, called SSMS, to efficiently embed the desired security attributes in the SMS messages to be used as a secure bearer in the m-payment systems. SSMS efficiently embeds the confidentiality, integrity, authentication, and non-repudiation in the SMS messages. It provides an elliptic curve-based public key solution that uses public keys for the secret key establishment of a symmetric encryption. It also provides the attributes of public verification and forward secrecy. It efficiently makes the SMS messaging suitable for the m-payment applications where the security is the great concern.

description: This paper presents an exploratory production study of Bharatanatyam, a figurative (narrative) dance. We investigate the encoding of coreference vs. disjoint reference in this dance and argue that a formal semantics of narrative dance can be modeled in line with Abusch’s (2013, 2014, 2015) semantics of visual narrative (drawing also on Schlenker’s, 2017a, approach to music semantics). A main finding of our investigation is that larger-level group-boundaries (Charnavel, 2016) can be seen as triggers for discontinuity inferences (possibly involving the dynamic shift from one salient entity to another). Keywords: co-reference, disjoint reference, dance semantics, iconic semantics, picture semantics.

Two-loop Integrability of Planar N=6 Superconformal Chern-Simons Theory

description: Bethe ansatz equations have been proposed for the asymptotic spectral problem of AdS_4/CFT_3. This proposal assumes integrability, but the previous verification of weak-coupling integrability covered only the su(4) sector of the ABJM gauge theory. Here we derive the complete planar two-loop dilatation generator of N=6 superconformal Chern-Simons theory from osp(6|4) superconformal symmetry. For the osp(4|2) sector, we prove integrability through a Yangian construction. We argue that integrability extends to the full planar two-loop dilatation generator, confirming the applicability of the Bethe equations at weak coupling. Further confirmation follows from an analytic computation of the two-loop twist-one spectrum.

Underspecified changes: a dynamic, probabilistic frame theory for verbs

description: The verb ‘rise’ can be used both with property-denoting nouns like ‘temperature’ but also with NPs like ‘a Titan’ or ‘China’. Whereas in the former case the change triggered by a rising event is directly related to the subject (its current value increases), this does not hold for ‘a titan’ or ‘China’. In this case it is a property of these objects, say their height or their political power, which increases in value. Furthermore, ‘rise’ does not target a particular property as the examples above show. This data has led Cooper (2010) to the conclusion that it is presumably not possible (i) “to extract a single general meaning of words which covers all the particular meanings of the word in context”, and (ii) “to determine once and for all the set of particular contextually determined meanings of a word”. In this article we present a solution to the two problems raised by ‘rise’ in a frame theory. ‘Rise’ is analyzed as a scalar verb which does not lexicalize a complete scale in its meaning. Rather, it shows underspecification relative to the dimension (property) parameter of a scale. The set of admissible properties is determined by a constraint on the value ranges of properties. If the property is not uniquely determined by the subject, the comprehender uses probabilistic reasoning based on world knowledge and discourse information to defeasibly infer the most likely candidates from this set (2nd problem). The first problem is solved not by simply introducing objects into the representation of a discourse but instead by pairs consisting of an object and an associated frame component which collects the object information contributed by the discourse. Changes triggered by events like the one denoted by ‘rise’ are modelled as update operations on the frame component while the object component is left unchanged. Keywords: lexical semantics, scalar changes, frame theory, probabilities.

Electronic conduction and dielectric properties of thin insulating films
Creators: name: Shousha, Abdel Halim Mahmoud
Publisher: name: University of British Columbia

description: The work contained in this thesis is concerned mainly with conduction mechanisms and polarization processes in thin amorphous insulating films. A model has been proposed and its d.c. conduction characteristics computed. The numerical results show the possibility of obtaining either space charge, Schottky, or Poole-Frenkel characteristics depending on the model parameters. The transient electronic discharge current has been analysed and the results show that this electronic current is approximately independent of the preapplied voltage in contrast to the ionic discharge current which is linearly dependent on preapplied voltage. This result, together with the experimental results obtained on Ta/Ta₂O₅/Au diodes, suggests that the calculations of low frequency dielectric losses using step response measurements are complicated by space charge effects only when the preapplied field is relatively low (≤lMV/cm for Ta₂0₅ films). Ta/Ta₂O₅/Au diodes were prepared by solution anodization or plasma anodization. All prepared diodes exhibited a rectification behaviour. Over the frequency range 100 Hz -100 kHz capacitance and loss tangent were found to decrease slightly with increasing frequency while the equivalent series resistance was found to be approximately proportional to ω⁻¹‧º⁵. All prepared diodes, with gold counter electrodes less than 1000 Å thick, were found to withstand, under a slowly applied field, field strengths approaching the formation field value.

description: We show that (equivariant) K-theoretic 3-point Gromov-Witten invariants of genus zero on a Grassmann variety are equal to triple intersections computed in the ordinary (equivariant) K-theory of a two-step flag manifold, thus generalizing an earlier result of Buch, Kresch, and Tamvakis. In the process we show that the Gromov-Witten variety of curves passing through 3 general points is irreducible and rational. Our applications include Pieri and Giambelli formulas for the quantum K-theory ring of a Grassmannian, which determine the multiplication in this ring. Our formula for Gromov-Witten invariants can be partially generalized to cominuscule homogeneous spaces by using a construction of Chaput, Manivel, and Perrin.

Some kind of relative clause
Creators: name: Mendia, Jon Ander
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: Amount Relatives (ARs) differ from restrictive relative clauses in that they do not refer to a particular object denoted by the head of the relative clause, but to an amount of such objects (Carlson, 1977a; Heim, 1987). Traditionally, ARs have been regarded as degree expressions. In this paper I argue against this view and propose instead that amount interpretations of relative clauses are in fact a special case of kind interpretation. Keywords: kind reference, amounts, relative clauses.

Extreme nouns and maximizers
Creators: name: Masià, Melania S.
Publisher: name: ZAS Papers in Linguistics
Year: 2018

description: Maximizers (completamente ‘completely’, totalmente ‘totally’) are degree modifiers restricted to maximum standard adjectives. Spanish adjectives of completeness [ACs] (completo ‘complete’, total ‘total’) display a behavior similar to that of their adverbial counterparts when they combine with nouns like idiot. This paper argues that ACs are maximality modifiers of idiot-like nouns, which are defended to be gradable and denote extreme degrees of properties. Establishing a parallelism between adverbs and adjectives of completeness allows us to explore scalarity across categories and the relevance of scale structure in the nominal domain. Keywords: extreme nouns, maximizers, adjectives of completeness, scale structure, nominal gradability.
