description: The process of desertification is usually modeled as a first order transition, where a change of an external parameter (e.g. precipitation) leads to a catastrophic bifurcation followed by an ecological regime shift. However, vegetation elements like shrubs and trees undergo a stochastic birth-death process with an absorbing state; such a process supports a second order continuous transition with no hysteresis. We present a numerical study of a minimal model that supports bistability and catastrophic shift on spatial domain with demographic noise and an absorbing state. When the external parameter varies adiabatically the transition is continuous and the front velocity renormalizes to zero at the extinction transition. Below the transition one may identify three modes of desertification: accumulation of local catastrophes, desert invasion and global collapse. A catastrophic regime shift occurs as a dynamical hysteresis, when the pace of environmental variations is too fast. We present some empirical evidence, suggesting that the mid-holocene desertification of the Sahara was, indeed, continuous.
Focus dependency as structure sharing
Creators: name: Sauerland, Uli
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Focus dependency is an important phenomenon at the syntax-semantics interface: Elided material can exhibit bound-variable-like behavior when its antecedent is a focussed phrase in the same sentence. In the past, focus dependency has been analyzed as actual binding or by means of copying. This paper presents a new account of focus dependency that relies on structure-sharing. Structure-sharing allows subphrases to be syntactically linked to more than one position of a phrase marker. The proposal better explains focus dependency than existing accounts especially when we consider novel data from the interaction of focus-dependency and MaxElide.

description: We consider evidentials embedded in complement clauses with new data from Bulgarian. For Tibetan, Garrett has shown that embedded evidentials are always shifted to the perspective of the reported speech. In Bulgarian, we show that such a shift is almost never possible. This shows that Bulgarian evidentials should not be analyzed as modals, but rather as presuppositional.

description: Implementing a scalable quantum information processor using polar molecules in optical lattices requires precise control over the long-range dipole-dipole interaction between molecules in selected lattice sites. We present here a scheme using trapped open-shell $^2Σ$ polar molecules that allows dipolar exchange processes between nearest and next-nearest neighbors to be controlled to construct a generalized transverse Ising spin Hamiltonian with tunable $XX$, $YY$ and $XY$ couplings in the rotating frame of the driving lasers. The scheme requires a moderately strong bias magnetic field with near-infrared light to provide local tuning of the qubit energy gap, and mid-infrared pulses to perform rotational state transfer via stimulated Raman adiabatic passage. No interaction between qubits is present in the absence of the infrared driving. We analyze the fidelity of the resulting two-qubit matchgate, and demonstrate its robustness as a function of the driving parameters. We discuss a realistic application of the system for universal matchgate quantum computing in optical lattices.

description: Optimal transport is one of the primary goals for designing efficient quantum networks. In this work, the maximum transport is investigated for three-dimensional quantum networks with Platonic geometries affected by dephasing and dissipative Markovian noise. The network and the environmental characteristics corresponding the optimal design are obtained and investigated for five Platonic networks with 4, 6, 8, 12, and 20 number of sites that one of the sites is connected to a sink site through a dissipative process. Such optimal designs could have various applications like switching and multiplexing in quantum circuits.

description: We present a proof of an upper tail bound of the correct order (up to a constant factor in the exponent) in two classes of stationary models in the KPZ universality class. The proof is based on an exponential identity due to Rains in the case of Last Passage Percolation with exponential weights, and recently re-derived by Emrah-Jianjigian-Seppäiläinen (EJS). Our proof follows very similar lines for the two classes of models we consider, using only general monotonocity and convexity properties, and can thus be expected to apply to many other stationary models.

The logic of the typicality judgments
Creators: name: Sassoon, Galit W.
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The standard model theoretical view of wrd meaning is incompatible with known facts about natural categories ('the typicality effects'), which experimental studies in cognitive psychology robustly support. Parts 1-3 of this paper present and criticize Kamp and Partee's 1995 well known analysis of the typicality effects. The main virtue of this analysis is in the use of supermodels, rather than fuzzy models, in order to represent vagueness in predicate meaning. The main problem is that typicality of an item in a predicate is represented by a value assigned by a measure function, indicating the proportion of supervaluations in which the item falls under the predicate. A number of issue cannot be correctly represented by the measure function, including the typicality effects in sharp predicates; the conjunction fallacy; the context dependency of the typicality effects, etc. In Parts 4-5, it is argued that these classical problems are solved if the typicality ordering is taken to be the order in which entities are learnt to be denotation members (or non-members) through contexts and their extensions. A modified formal model is presented, which clarifies the connnections between the typicality effects, predicate meaning and its acquisition.

description: The data acquisition (DAQ) system of the SND detector successfully operated during four data-taking seasons (2010-2013) at the e+e- collider VEPP-2000. Currently the collider is shut down for planned reconstruction, which is expected to increase the VEPP-2000 luminosity and data flow from the SND detector electronics by up to 10 times. Since current DAQ system implementation (electronics and computer part) does not have enough reserve for selection of events in the new environment without compromising quality, there arose the need for the system upgrade. Here we report on the major SND data acquisition system upgrade which includes developing new electronics for digitization and data transfer, complete redesign of the data network, increasing of the DAQ computer farm processing capacity and making the event building process concurrent. These measures will allow us to collect data flow from the most congested detector subsystems in parallel in contrast to the current situation. We would like to discuss also the possibility to implement full software trigger solution in the future.

description: Based on data from German, I call attention to a so far unnoticed relationship between data on complement set anaphora and strong negative polarity items (NPI). In particular, I show that if a quantified NP can serve as antecedent of a complement set anaphor, it can also license strong NPIs. I provide a lexical decomposition analysis using Discourse Representation Theory.

description: This dissertation explores the Lithium-Sulfur battery as one chemistry that promises a safer, higher energy density, cheaper, and more sustainable storage technology. Cellulose, being a versatile, inexpensive and tunable material, can be used to prepare stable battery electrodes. In this thesis, the focus is on exploring cellulose-based binders in the fabrication of high-performing sulfur cathodes.

description: The star V2282 Sgr is positionally consistent with a strong Chandra X-ray and a Spitzer/IRAC MIR source. We derived its long term $I$-band light curve from the photographic archives of the Asiago and Catania Observatories, covering the years from 1965 to 1984. CCD $R_C$ photometry in Summer 2009 was re-analyzed. Optical spectra were secured at Loiano Observatory in 2011 and 2012. J H K photometry, obtained from several experiments in different epochs was compared and the Spitzer images were re-analyzed. V2282 Sgr was found to be irregular variable in all wavelengths. Spectroscopically, it shows strong emission features (H Balmer lines, [NII]6584 AA and [OIII]5007/4959 AA) while the Na D doublet is very strong, indicating a circumstellar envelope. A single thermal energy distribution cannot reproduce the observed SED, while it can be explained as the sum of a G-type star plus a variable circumstellar disc, which mimics a class 0/I object. Most likely, V2282 Sgr is a 1-2 $M_{sun}$ mass pre main sequence star with an accretion disk.

description: Free Choice any and Negative Polarity Item any are uniformly analyzed as counterfactual donkey sentences (in disguise). Their difference in meaning will be reduced to the distinction between strong and weak readings of donkey sentences. It is shown that this explains the universal and existential character of FC- and NPI-any, respectively, and the positive and negative contexts in which they are licensed.

What asymmetric coordination in German tells us about the syntax and semantics of conditionals
Creators: name: Reich, Ingo
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Although there is a vast amount of literature on the semantics of conditionals, there is usually little said about the way conditionals are interpreted compositionally. And if there is, it is often suggested that it sufﬁces to consider conditionals like “if S1, then S2”, taking for granted that coordinate structures like “if S1 and S2, then S3” can be reduced in form to the former, for it seems quite obvious that coordination takes place within the syntactic scope of if (i.e., we have “if [S1 and S2], then S3”). In this paper, I will argue that this is not obvious at all. I will show that there is good empirical evidence that (at least) in the case of so-called Asymmetric Coordination in German (Ho¨ hle 1990) coordination does not take place within the syntactic scope of if (i.e., we have “[[if S1] and S2], then S3”). This apparently gives rise to a mismatch between syntax and semantics, which —if I am right— can only be (straightforwardly) resolved in a Lewis/Kratzer approach to the semantics of conditionals. To account for some problems related to distributive readings, I will ﬁnally propose that if is to be interpreted as a variable picking up a modal base in context.

description: We provide an account of the alignment of linguistic form and discourse function with respect to English tag questions, adopting as a formal framework Segmented Discourse Representation Theory. SDRT models the discourse function of utterances via their rhetorical connection to the antecedent discourse. We pay particular attention to the prosodic features of tag questions and their contribution to interpretation. This approach to tag questions is appropriate, we argue, as the interpretation of a tag comes down to its rhetorical connection to the host sentence.

description: We present the first Bayesian method for tomographic decomposition of the plane-of-sky orientation of the magnetic field with the use of stellar polarimetry and distance. This standalone tomographic inversion method presents an important step forward in reconstructing the magnetized interstellar medium (ISM) in 3D within dusty regions. We develop a model in which the polarization signal from the magnetized and dusty ISM is described by thin layers at various distances. Our modeling makes it possible to infer the mean polarization (amplitude and orientation) induced by individual dusty clouds and to account for the turbulence-induced scatter in a generic way. We present a likelihood function that explicitly accounts for uncertainties in polarization and parallax. We develop a framework for reconstructing the magnetized ISM through the maximization of the log-likelihood using a nested sampling method. We test our Bayesian inversion method on mock data taking into account realistic uncertainties from Gaia and as expected for the optical polarization survey PASIPHAE according to the currently planned observing strategy. We demonstrate that our method is effective at recovering the cloud properties as soon as the polarization induced by a cloud to its background stars is higher than $\sim 0.1\%$ for the adopted survey exposure time and level of systematic uncertainty. Our method makes it possible to recover not only the mean polarization properties but also to characterize the intrinsic scatter, thus creating new ways to characterize ISM turbulence and the magnetic field strength. Finally, we apply our method to an existing data set of starlight polarization with known line-of-sight decomposition, demonstrating agreement with previous results and an improved quantification of uncertainties in cloud properties.

Context shifting in questions and elsewhere
Creators: name: McCready, Eric
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: It has been shown that context shifting takes place within propositional attitudes. This paper argues that there are other environments where context shift takes place, specifically in questions and in the scope of modal and evidential operators. It is argued that the shift that takes place is a shift in the judge, the individual who determines truth and falsity (of non-objective content). The shift is analyzed in terms of monstrous operators.

Interstellar gamma-ray emission from cosmic rays in star-forming galaxies

Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Fermi/LAT observations of star-forming galaxies in the ~0.1-100GeV range have made possible a first population study. Evidence was found for a correlation between gamma-ray luminosity and tracers of the star formation activity. Studying galactic cosmic rays (CRs) in various global conditions can yield information about their origin and transport in the interstellar medium (ISM). This work addresses the question of the scaling laws that can be expected for the interstellar gamma-ray emission as a function of global galactic properties, with the goal of establishing whether the current experimental data in the GeV range can be constraining. I developed a 2D model for the non-thermal emissions from steady-state CR populations interacting with the ISM in star-forming galaxies. Most CR-related parameters were taken from Milky Way studies, and a large number of galaxies were then simulated with sizes from 4 to 40kpc, several gas distributions, and star formation rates (SFR) covering six orders of magnitude. The evolution of the gamma-ray luminosity over the 100keV-100TeV range is presented, with emphasis on the contribution of the different emission processes and particle populations, and on the transition between transport regimes. The model can reproduce the normalisation and trend inferred from the Fermi/LAT population study over most of the SFR range. This is obtained with a plain diffusion scheme, a single diffusion coefficient, and the assumption that CRs experience large-scale volume-averaged interstellar conditions. There is, however, no universal relation between high-energy gamma-ray luminosity and star formation activity, as illustrated by the scatter introduced by different galactic global properties and the downturn in gamma-ray emission at the low end (abridged).

description: We develop a curvilinear invariant set of the diffusion tensor which may be applied to Diffusion Tensor Imaging measurements on tissues and porous media. This new set is an alternative to the more common invariants such as fractional anisotropy and the diffusion mode. The alternative invariant set possesses a different structure to the other known invariant sets; the second and third members of the curvilinear set measure the degree of orthotropy and oblateness/prolateness, respectively. The proposed advantage of these invariants is that they may work well in situations of low diffusion anisotropy and isotropy, as is often observed in tissues such as cartilage. We also explore the other orthogonal invariant sets in terms of their geometry in relation to eigenvalue space; a cylindrical set, a spherical set (including fractional anisotropy and the mode), and a log-Euclidean set. These three sets have a common structure. The first invariant measures the magnitude of the diffusion, the second and third invariants capture aspects of the anisotropy; the magnitude of the anisotropy and the shape of the diffusion ellipsoid (the manner in which the anisotropy is realised). We also show a simple method to prove the orthogonality of the invariants within a set.

description: This is a study on the worldview of rice farmers on agroenterprise, and their communicative practices. Using qualitative methodology, I analyzed empirical data from rice-based agroenterprise engaged farmers to answer the following research questions: What is the view of the farmers on agroenterprise, and How does their view define their communicative practices as entrepreneurs. Ethnomethodology was chosen as the research framework of this study for its ability to examine the contextual use or conduct of mundane activities enabling researchers to have specified data on practice. Though this specified ability of ethnomethodology may limit the application of the findings, it could be compensated for its capacity to observe and retrieve knowledge and skills in day-to-day activities. I found out that the rice farmers see their agroenterprise venture as an advanced farming activity, and this advanced farming activity is communicated through their three main practices of Financial preparedness and acumen developed; Farming practices enhanced, and Filial obligations accomplished. Financial preparedness and acumen developed is broken down into Saving is essential, Farm diversification for multiple sources of income, and Practical entrepreneurial knowledge and skills are used. While Farming practices enhanced is further defined by the rice farmers as Recordkeeping improved farm management, and Appropriate farming technologies are applied. As an advanced farming activity, these agroenterprise communicative practices are the necessities by which other rice farmers may need to accomplish to engage in entrepreneurial activities. Based on the findings of this study, I came up with methodological and practical recommendations on the implementation and conduct of agroenterprise-based extension initiatives.
Magnetic Flux Transport in Radiatively Inefficient Accretion Flows and the Pathway towards a Magnetically Arrested Disk

description: Large-scale magnetic fields play a vital role in determining the angular momentum transport and generating jets/outflows in the accreting systems, yet their origin remains poorly understood. We focus on radiatively inefficient accretion flows (RIAFs) around the black holes (BHs), and conduct three-dimensional general-relativistic magnetohydrodynamic (GRMHD) simulations using the Athena++ code. We first re-confirm that the MRI dynamo in the RIAF alone does not spontaneously form a magnetically arrested disk (MAD), conducive for strong jet formation. We next investigate the other possibility, where the large-scale magnetic fields are advected inward from external sources (e.g. the companion star in X-ray binaries, magnetized ambient medium in AGNs). Although the actual configuration of the external fields could be complex and uncertain, they are likely to be closed. As a first study, we treat them as closed field loops of different sizes, shapes and field strengths. Unlike earlier studies of flux transport, where magnetic flux is injected in the initial laminar flow, we injected the magnetic field loops in the quasi-stationary turbulent RIAF in inflow equilibrium and followed their evolution. We found that a substantial fraction ($\sim15\%-40\%$) of the flux injected at the large radii reaches the BH with a weak dependence on the loop parameters except when the loops are injected at high latitudes, away from the mid-plane. Relatively high efficiency of flux transport observed in our study hints that a MAD might be formed relatively easily close to the BH, provided that a source of the large-scale field exists at the larger radii.

Proper names as rigid presuppositions
Creators: name: Maier, Emar
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Since Kripke introduced rigid designation as an alternative to the Frege/Russell analysis of referential terms as definite descriptions, there has been an ongoing debate between ‘descriptivists’ and ‘referentialists’, mostly focusing on the semantics of proper names. Nowadays descriptivists can draw on a much richer set of linguistic data (including bound and accommodated proper names in discourse) as well as new semantic machinery (E-type syntax/semantics, DRT, presupposition-as-anaphora) to strengthen their case. After reviewing the current state of the debate, I argue for a referentialist semantics that incorporates some modern insights from the side of the descriptivists in order to account for the new data in a principled fashion.

description: We present a general framework for calculating post-Minskowskian, classical, conservative Hamiltonians for $N$ non-spinning bodies in general relativity from relativistic scattering amplitudes. Novel features for $N>2$ are described including the subtraction of tree-like iteration contributions and the calculation of non-trivial many-body Fourier transform integrals needed to construct position space potentials. A new approach to calculating these integrals as an expansion in the hierarchical limit is described based on the method of regions. As an explicit example, we present the $\mathcal{O}\left(G^2\right)$ 3-body momentum space potential in general relativity as well as for charged bodies in Einstein-Maxwell. The result is shown to be in perfect agreement with previous post-Newtonian calculations in general relativity up to $\mathcal{O}\left(G^2 v^4\right)$. Furthermore, in appropriate limits the result is shown to agree perfectly with relativistic probe scattering in multi-center extremal black hole backgrounds and with the scattering of slowly-moving extremal black holes in the moduli space approximation.

description: Hausdorff and box dimension are two familiar notions of fractal dimension. Box dimension can be larger than Hausdorff dimension, because in the definition of box dimension, all sets in the cover have the same diameter, but for Hausdorff dimension there is no such restriction. This thesis focuses on a family of dimensions parameterised by θ ∈ (0,1), called the intermediate dimensions, which are defined by requiring that diam(U) ⩽ (diam(V))ᶿ for all sets U, V in the cover. We begin by generalising the intermediate dimensions to allow for greater refinement in how the relative sizes of the covering sets are restricted. These new dimensions can recover the interpolation between Hausdorff and box dimension for compact sets whose intermediate dimensions do not tend to the Hausdorff dimension as θ → 0. We also use a Moran set construction to prove a necessary and sufficient condition, in terms of Dini derivatives, for a given function to be realised as the intermediate dimensions of a set. We proceed to prove that the intermediate dimensions of limit sets of infinite conformal iterated function systems are given by the maximum of the Hausdorff dimension of the limit set and the intermediate dimensions of the set of fixed points of the contractions. This applies to sets defined using continued fraction expansions, and has applications to dimensions of projections, fractional Brownian images, and general Hölder images. Finally, we determine a formula for the intermediate dimensions of all self-affine Bedford–McMullen carpets. The functions display features not witnessed in previous examples, such as having countably many phase transitions. We deduce that two carpets have equal intermediate dimensions if and only if the multifractal spectra of the corresponding uniform Bernoulli measures coincide. This shows that if two carpets are bi-Lipschitz equivalent then the multifractal spectra are equal.
Free choice items and definiteness: Evidence from Greek

I argue that bare opjosdhipote or opjosdhipote co-appearing with the definite article is a determiner, while opjosdhipote co-appearing with the indefinite article is an adjective and that the definite article in the construction in question does not contribute definiteness, as would be expected, but acts as a slack regulator in the sense of Lasersohn (1999).

Semantics of the cardinal partitive construction
Creators: name: Kobuchi-Philip, Mana
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper proposes a semantic analysis of cardinal partitive sentences such as Three of the boys left. Its three components are: (i) the traditional 'two NP-hypothesis' of Jackendoff (1977), (ii) the traditional semantics of the preposition of of Ladusaw (1982) and Hoeksema (1983), and (iii) the semantic analysis of the numeral recently suggested in Kobuchi-Philip (2006b). Specifically, for a cardinal partitive DP such as three of the boys, the presence of a phonetically null classifier, a phonetically null NP, and a phonetically null determiner is hypothesized. These assumptions form the basis for the proposed unified semantic analysis, which accounts for the cardinal partitive sentence both in classifier languages such as Japanese and in non-classifier languages such as English.

We show this with the next-to-leading order non-linear bispectrum for a pressureless fluid in a flat Friedmann-Robertson-Walker background, by calculating the density and velocity fields up to fourth order. We work in the comoving gauge, where the dynamics is identical to the Newtonian up to second order. We also discuss the leading order matter bispectrum in various gauges, and show yet another relativistic effect near horizon scales that the matter bispectrum strongly depends on the gauge choice.

description: The half-infinite XXZ spin chain with a triangular boundary is considered in the massive regime. Two integral representations of form factors of local operators are proposed using bosonization. Sufficient conditions such that the expressions for triangular boundary conditions coincide with those for diagonal boundary conditions are identified. The expressions are compared with known results upon specializations.Using the spin-reversal property which relates the Hamiltonian with upper and lower triangular boundary conditions, new identities between multiple integrals of infinite products are extracted.

description: Generally, moso bamboo (Phyllostachys edulis) has three types of color patterns at the internodes of clums. P. edulis f. luteosulcata (YM) has green slot & yellow wall at internode, but P. edulis f. viridisulcata (GM) have an adverse phenotype with green wall & yellow slot. The protype of moso bamboo (P. edulis f. pubescens; MB) has green intenodes. To figure out the generation of culms with different color patterns, intercalary meristems of tender internodes were collected at the early stage with inconspicuous colors and at the late stage with distinct colors from the three types of moso bamboo.

description: Several strategies were implemented to address rabies disease as a public health issue, but very few were written about how responsible pet ownership can resolve it. Recognizing responsible pet ownership as a key in eliminating rabies disease in the Philippines, this study determined what influences dog owners in adopting responsible pet ownership as a rabies preventive measure. Specifically, this study determined how exposure to rabies, knowledge and practices, perceptions on the risk and the benefits of avoiding the risk, self-efficacy, and awareness to CVO's Anti-Rabies Program, are related to dog owners' decision to become responsible pet owners. Guided by the framework of the Health Belief Model (HBM), this study utilized the convergent mixed method design. Quantitative data were gathered through an online survey which was participated by a total of sixty (60) dog owners. The respondents are residents of the top three barangays with the highest number of rabies cases reported in Davao City in 2018. On the other hand, qualitative data were gathered through a key informant interview with City Veterinarian's Office and Focus Group Discussions (FGDs) with pet owners residing in the mentioned barangays. Quantitative and qualitative results revealed that the research participants have a high level of knowledge on rabies, high level of perceived threat, high level of perceived susceptibility, high level of perceived benefits, and moderate level of perceived barriers. These factors account for the HBM construct 'readiness to act'. Moreover, based on the results, participants have a very high level of self-efficacy. This means that the respodents are confident in their ability to successfully practice responsible pet ownership. As to the level of awareness on CVO's Rabies Prevention and Control Program, results show that participants are not very well informed about it, especially on its implementation at the barangay level. The level of awareness on the program is under the HBM construct 'cues to action' which refers to factors that activate that readiness and stimulates action. Further, results of the correlation analysis revealed that only the level of awareness on the program has a significant relationship with the level of adherence to responsible pet ownership practices. This implies that as the awareness on the CVO's programs increases, the level of adherence to the recommended practices also increases. Therefore, 'cues to action' has a significant influence on respondents' adherence to responsible pet ownership practices as a rabies preventive measure.

description: Elastic nucleon-pion scattering amplitudes are computed using lattice QCD on a single ensemble of gauge field configurations with $N_{\rm f} = 2+1$ dynamical quark flavors and $m_π = 200~{\rm MeV}$. The $s$-wave scattering lengths with both total isospins $I=1/2$ and $I=3/2$ are inferred from the finite-volume spectrum below the inelastic threshold together with the $I=3/2$ $p$-wave containing the $Δ(1232)$ resonance. The amplitudes are well-described by the effective range expansion with parameters constrained by fits to the finite-volume energy levels enabling a determination of the $I=3/2$ scattering length with statistical errors below $5\%$, while the $I = 1/2$ is somewhat less precise. Systematic errors due to excited states and the influence of higher partial waves are controlled, providing a pathway for future computations down to the physical light quark masses with multiple lattice spacings and physical volumes.

Domain restriction in freedom of choice: A view from Korean indet-na items
Creators: name: Kim, Min-Joo
name: Kaufmann, Stefan
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The Korean Free Choice Items (FCI) nwukwu-na and amwu-na are composed of the indeterminates nwukwu /amwu and the particle -na. These items are particularly interesting from the perspective of the theory of FCI for at least two reasons: First, while both share the general meaning of “free choice,” they exhibit important differences in detail which highlight the multifaceted nature of this category. Second, their relatively transparent morphological structure calls for a compositional analysis which locates the source of the differences between them in the indeterminates nwukwu and amwu and gives a uniﬁed analysis to the particle -na. This is a challenge because it means that while the particle is the source of the “free choice-ness” of the compounds, it cannot be held responsible for certain properties that are considered typical of FCI in general, yet are not shared by both nwukwu-na and amwu-na. In this paper, we present an overview of several semantic difference between the items, followed by a formal analysis of some of those differences, speciﬁcally regarding their implicatures with respect to intensionality and counterfactuality.

description: Yeast, a single eukaryotic cell model organism, demonstrates a progressive aging process. In the era of synthetic biology, study of the impact of synthetic chromosomes and aging is urgent and intriguing. Herein, we successfully constructed the 884 Kb synXIII of Saccharomyces cerevisiae and conducted replicative aging studies using the synthetic strains. We verified that the rRNA-related transcriptional factor RRN9 is a major positive controller of replicative lifespan. Using SCRaMbLE and an HSP104 reporter as a biomarker for mutant discovery, we screened 135 SCRaMbLEd synXIII strains with extended lifespan and identified 10 genes on synXIII that potentially serve as aging regulators. In addition, the genome-scale regression analysis of long-replicative lifespan SCRaMbLEd strains revealed distinct dysregulation of nucleus, ribosome, and mitochondrion function networks. Our findings suggest that Sc2.0 yeast has potential for unveiling new aging-related genes and gene-gene interactions underlying replicative lifespan.
The posture verb progressive in Icelandic
Creators: name: Jóhannsdóttir, Kristín M.
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper I focus on a construction in Icelandic in which a coordination of two simple present/past verbs, where the first verb is a posture verb, gets a progressive reading. Those sentences indicate that the ‘two events’ take place simultaneously (at the reference time). That is, there is an event, which consists of two components, such as sitting and reading. The main question is: How does coordination with a posture verb yield a progressive reading? The proposed solution to this posture-verb progressive puzzle involves the claim that the conjunction og ‘and’ does not have the semantics of conjunction here, and that we do not have two events but one. Furthermore, I argue that the fact that posture verb coordinations get a progressive reading comes from a mismatch in the status of the external argument, building on Kratzer (1994). ‘Sitting’ is a state and calls for a ‘holder’ external argument, whereas ‘reading’ is an event which calls for an ‘agent’ argument. I assume that external arguments cannot at the same time be an agent and a holder of an event. However, this can be solved in two ways. One is by adding an external argument, such that we have both an agent-argument and a holder-argument. That results in two separate events, and doesn’t get a progressive reading. The other way of solving this is by coercing ‘read’ to be a state. Now one external argument, a holder, satisfies both verbs. Because of this coercion of an event to a state, the reading we get is that an event that is both a sitting and a reading holds at a certain time. As all states are imperfective this coercion of the event verb to a state makes it imperfective and as Icelandic doesn’t have an imperfective construction separate from the progressive Icelanders understand these sentences as progressive. This is why these posture verb co-ordinations result in a progressive reading rather than a perfective one.

description: We propose efficient numerical methods for nonseparable non-canonical Hamiltonian systems which are explicit, K-symplectic in the extended phase space with long time energy conservation properties. They are based on extending the original phase space to several copies of the phase space and imposing a mechanical restraint on the copies of the phase space. Explicit K-symplectic methods are constructed for three non-canonical Hamiltonian systems. Numerical results show that they outperform the higher order Runge-Kutta methods in preserving the phase orbit and the energy of the system over long time.
