description: Background

Maternal Common Mental Disorders (CMD), including depression and anxiety, are recogniz ed

to have important public health consequences in lowand

middleincome

countries (LMICs). In

Ethiopia, maternal CMDs have been associated with increased infant diarrhea, impaired child

development and increased child mortality. Crosssectional

studies show associations between

poverty and maternal CMD in LMICs, but the temporal relationship is unclear.

Objectives: the aim of this study was to investigate the association between poverty and

maternal CMD, to assess incidence of poverty and maternal CMD.

Methods: a retrospective cohort study design was conducted. The CMaMiE

study recruited

pregnant women (aged 15 – 49 years). CMD has been measured using WHO’s SelfReporting

Q uestionnaire. Poverty was constructed using Mokken scaling procedure during pregnancy and

having two or more subjective poverty report at the follow up time. Poisson and binary logistic

regression analyses were performed

description: The WASP-Index is computed over Iberia for three monthly timescales in 1961-2020, based on an observational gridded precipitation dataset (E-OBS), and in 2021-2070, based on bias-corrected precipitation generated by a six-member climate model ensemble from EURO-CORDEX, under RCP4.5 and RCP8.5. The WASP performance in identifying extremely dry or wet events, reported by the EM-DAT disaster database, is assessed for 1961–2020. An overall good agreement between the WASP spatial patterns and the EM-DAT records is found. The areolar mean values revealed an upward trend in the frequency of occurrence of intermediate-to-severe dry events over Iberia, which will be strengthened in the future, particularly for the 12m-WASP intermediate dry events under RCP8.5. Besides, the number of 3m-WASP intermediate-to-severe wet events is projected to increase, mostly the severest events under RCP4.5, but no evidence was found for an increase in the number of more persistent (12m-WASP) wet events under both RCPs. Despite important spatial heterogeneities, an increase(decrease) of the intensity, duration, and frequency of occurrence of the 12m-WASP intermediate-to-severe dry(wet) events is found under both scenarios, mainly in the southernmost regions of Iberia, thus becoming more exposed to prolonged and severe droughts in the future, corroborating the results from previous studies.

description: The quiescent state is the dominant accretion mode for black holes on all mass scales. Our knowledge of the X-ray spectrum is limited due to the characteristic low luminosity in this state. Herein, we present an analysis of the sample of dynamically-confirmed stellar-mass black holes observed in quiescence in the \textit{Chandra/XMM-Newton/Suzaku} era resulting in a sample of 8 black holes with $\sim$ 570 ks of observations. In contrast to the majority of AGN where observations are limited by contamination from diffuse gas, the stellar-mass systems allow for a clean study of the X-ray spectrum resulting from the accretion flow alone. The data are characterized using simple models. We find a model consisting of a power-law or thermal bremsstrahlung to both provide excellent descriptions of the data, where we measure $\rm Γ= 2.06 \pm 0.03$ and $\rm kT = 5.03^{+0.33}_{-0.31} keV$ respectively in the 0.3 -- 10 keV bandpass, at a median luminosity of $\rm L_x \sim 5.5\times10^{-7} L_{Edd}$. This result in discussed in the context of our understanding of the accretion flow onto stellar and supermassive black holes at low luminosities.

description: Recent years have witnessed the great successes of embedding-based methods in recommender systems. Despite their decent performance, we argue one potential limitation of these methods -- the embedding magnitude has not been explicitly modulated, which may aggravate popularity bias and training instability, hindering the model from making a good recommendation. It motivates us to leverage the embedding normalization in recommendation. By normalizing user/item embeddings to a specific value, we empirically observe impressive performance gains (9\% on average) on four real-world datasets. Although encouraging, we also reveal a serious limitation when applying normalization in recommendation -- the performance is highly sensitive to the choice of the temperature $τ$ which controls the scale of the normalized embeddings. To fully foster the merits of the normalization while circumvent its limitation, this work studied on how to adaptively set the proper $τ$. Towards this end, we first make a comprehensive analyses of $τ$ to fully understand its role on recommendation. We then accordingly develop an adaptive fine-grained strategy Adap-$τ$ for the temperature with satisfying four desirable properties including adaptivity, personalized, efficiency and model-agnostic. Extensive experiments have been conducted to validate the effectiveness of the proposal. The code is available at \url{https://github.com/junkangwu/Adap_tau}.
Empirical investigations on quantifier scope ambiguities in German
Creators: name: Philipp, Mareike
name: Zimmermann, Malte
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: The paper presents the results of a novel experimental study on inverse scope readings in German, which are considered to be possible only under highly constrained conditions in prior literature (Frey 1993; Pafel, 2005; Bobaljik & Wurmbrand, 2012). We show that inverse scope readings are in fact possible in canonical main clauses with an -subject QP preceding and c-commanding an -object QP under verum focus, with the potential of object- scrambling over the subject. The existing literature on quantifier scope in German is unanimous in claiming that inverse scope is impossible in this configuration. Our findings are line with previous experiments on German that found inverse readings to be available in other syntactic configurations (e.g. Bott & Radó, 2007; Radó & Bott 2011; Bott & Schlotterbeck, 2015). Moreover, the availability of inverse readings is boosted when the context biases towards them, a finding which is compatible with previous evidence suggesting that context plays an important role in scope ambiguity resolution (Kurtzman & MacDonald, 1993; Saba & Corriveau, 2001; Villalta, 2003; Reinhart, 2006). Our results also suggest that inverse readings are not banned from relative clauses, a result that is incompatible with the assumptions that relative clauses are islands, and that inverse scope interpretations are obtained via the covert movement operation QR in syntax. Finally, we show that scope interpretation strategies differ drastically between speakers of the same language, in line with introspective judgments.

description: (21) Crassicorophium bonellii (H. Milne Edwards, 1830)
Status in U.K. – cryptogenic.
Crassicorophium bonellii has a widely reported distribution but the identity of the species is problematic and it is possible that a species complex is involved (Marchini and Cardeccia 2017). Chapman (2007) considered that C. bonellii was indistinguishable from Monocorophium acherusicum. In the current sampling programme C. bonellii has been found at Vanguard in 2013 and from a scrape sample at Gutter Sound in 2016 but it has also been recorded in MNCR surveys in 1995 and 1997 (Murray et al. 1999).
Its widespread nature and association with human vectors makes establishing the native range of the species problematic (Marchini and Cardeccia 2017) and we consider it to be a cryptogenic species in the U.K.

Generalized incrementality: The veridicality property of clause-embedding reveal-type predicates in Polish
Creators: name: Zuchewicz, Karolina
name: Szucsich, Luka
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: It is a common observation that the so-called incremental theme verbs like ‘eat’, ‘drink’ or ‘build’ enforce a gradual affectedness of a direct object by the verbal process (Dowty, 1991; Krifka, 1992 among others). In aspect languages like Polish, perfective incremental theme verbs imply a total affectedness: The object vanishes (in the case of ‘eat’ or ‘drink’), it appears in its totality (in the case of ‘build’) or is fully involved in any other way (for example in the case of ‘read’, where there are no unread pages left in a single reading event). In contrast, imperfective counterparts only imply partial affectedness of their objects (Wierzbicka, 1967; Filip, 1985, 1997, 1999; Krifka, 1989a, 1989b, 1989c, 1992). Crucially, the gradual/total affectedness relation between the verb and its object only holds for incremental theme verbs. For instance, seeing a sandwich, in contrast to eating a sandwich, neither changes anything in the structure of a sandwich nor does it necessarily relate to its parts. This paper shows that propositional objects are also subjected to verbal events in a gradual manner if a clause- embedding verb is an incremental theme verb. In this case, the counterpart to total affectedness is veridicality, i.e. the revelation of a truth-conditional object. Building upon Zuchewicz (2020), we propose an account of generalized incrementality. In this account, incrementality is defined on the level of events and does not enforce the object to be divided into parts (compared to Krifka, 1989a, 1989b, 1989c, 1992 among others). As a result, the analysis holds for all incremental theme verbs, regardless of the type of a complement they combine with. The justification for this line of reasoning comes from a diverse nature of incrementality. Our object of investigation are transitive verbs which, if realized by clause-embedding predicates, take a that-clause as a complement. Their incremental character cannot be captured by dividing a proposition expressed by a that-clause into parts, but by a gradual creation of a proof for an embedded proposition.

description: Fire disasters can pose a great threat to cultural heritage objects. The consequences of fire flames
 and fire effluents (FE) are almost always disastrous and still represent uncertainty regarding how and to
 what extent they affect the environment. Furthermore, their negative effect can continue long after the fire
 has been extinguished. The fire behaviour can nowadays be monitored by different devices, such as cone
 calorimeter (ISO-5660), smoke density chamber (ISO-5659), etc.
 In this work, we employed bench-scale test in order to study the influence of FE on the
 proteinaceous paint layers. Two sets of model samples (one containing lead white-egg yolk tempera paints
 and the other pure egg yolk binder applications) were prepared to follow and to better understand the overall
 fire impact (i.e., effects of temperature and FE). Untreated spruce was selected as burning material. Model
 samples were placed in special chambers (influence of FE) and in a special designed holder mounted on
 top of the cone calorimeter stack (influence of FE and increased temperature) during the exposure to FE.
 Overall experiment lasted approximately 20 minutes, while the temperature on top of the stack varied
 between 200 and 400 °C. Furthermore, the design of the experiment allowed the investigation of exposure
 time. Molecular changes of exposed samples have been investigated by non-invasive reflection and
 conventional FTIR, and Raman spectroscopy, while the colour change was evaluated by colourimetry. The
 latter increased in relation to time of exposure due to either paint degradation, adsorption of effluents and/or
 deposition of soot. The most significant changes were determined for the samples, exposed for longer
 times. The appearance of additional IR band placed at 1,529 cm–1 suggested the presence of iminium ion,
 which can form when protonated formaldehyde, generated by burning process of wood, react with protein
 amine group [1]. Moreover, other alteration products such as lead oxide, were also detected.
Degrees as kinds vs. degrees as numbers: Evidence from equatives
Creators: name: Zhang, Linmin
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: Within formal semantics, there are two views with regard to the ontological status of degrees: the ‘degree-as-number’ view (e.g., Seuren, 1973; Hellan, 1981; von Stechow, 1984) and the ‘degree-as-kind’ view (e.g., Anderson and Morzycki, 2015). Based on (i) empirical distinctions between comparatives and equatives and (ii) Stevens’s (1946) theory on the four levels of measurements, I argue that both views are motivated and needed in accounting for measurement- and comparison-related meanings in natural language. Specifically, I argue that since the semantics of comparatives potentially involves measurable differences, comparatives need to be analyzed based on scales with units, on which degrees are like (real) numbers. In contrast, since equatives are typically used to convey the non-existence of differences, equatives can be based on scales without units, on which degrees can be considered kinds.

Verbal negation

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: While it is well–known that negation has various behaviours, I focus here on verbal negation, a constituent negation acting on verbs. I show that propositional negation and verbal negation are barely distinguishable at matrix level, but that a real semantic difference is brought out in certain linguistic contexts, including direct perception reports. I link verbal negation with counter–expectation and active inaction, thus generalising previous accounts on negated infinitives in direct perception reports. I then propose a formalisation in a recent event semantics framework. Finally I explore how these ideas relate with previous studies in two languages featuring several negation forms: Korean and Bengali.

description: The interplay between topological defects, such as dislocations or disclinations, and the electronic degrees of freedom in graphene has been extensively studied. In the literature, for the study of this kind of problems, it is in general used either a gauge theory or a curved spatial Riemannian geometry approach, where, in the geometric case, the information about the defects is contained in the metric and the spin-connection. However, these topological defects can also be associated to a Riemann-Cartan geometry where curvature and torsion plays an important role. In this article we study the interplay between a wedge dislocations in a planar graphene sheet and the properties of its electronic degrees of freedom. Our approach relies in its relation with elasticity theory through the so called elastic-gauge, where their typical coefficients, as for example the Poisson's ratio, appear directly in the metric, and consequently also in the electronic spectrum.

description: This paper investigates the use of the Mandarin discourse particle ba in polar questions and wh-questions. With the introduction of a set of new scenarios where ba-interrogatives are (in-)felicitous, the paper shows that (i) ba-attached questions are typically used to challenge the presupposition of a contextually salient Question Under Discussion (henceforth QUD), and (ii) ba is particularly sensitive to the commitments from the addressee. These findings support the presence of a hierarchical discourse structure (Büring, 2003; Roberts, 1996), and the various components in the context.

Counterfactual wishing as multiple agreement
Creators: name: Wimmer, Alexander
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: Counterfactual (CF) wishes give rise to the wellknown puzzle that CF-marking on a desire predicate leaves the desire intact (von Fintel and Iatridou 2008, 2017). German is one of the languages that exhibits this pattern. This paper takes the desire’s intactness in German CF-wishes to speak in favor of viewing said CF-marking as semantically vacuous agreement morphology. All this morphology does is to reflect CF-displacement of a silent antecedent (vF&I 2017). The morphological pattern CF-wishes seem subject to might apply to CF-conditionals more generally.

Feeding and Feedback in nearby AGN - Comparison with the Milky Way center
Creators: name: Storchi-Bergmann, Thaisa
Publisher: name: arXiv
Year: 2014
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: I discuss feeding and feedback processes observed in the inner few hundred parsecs of nearby active galaxies using integral field spectroscopy at spatial resolutions of a few to tens of parsecs. Signatures of feedback include outflows from the nucleus with velocities ranging from 200 to 1000km/s, with mass outflow rates between 0.5 and a few Msun/yr. Signatures of feeding include the observation of gas inflows along nuclear spirals and filaments, with velocities ranging from 50 to 100km/s and mass flow rates from 0.1 to 1 Msun/yr. These rates are 2--3 orders of magnitude larger than the mass accretion rate to the supermassive black hole (SMBH). These inflows can thus lead, during less than one activity cycle, to the accumulation of enough gas in the inner few hundred parsecs, to trigger the formation of new stars, leading to the growth of the galaxy bulge. Young to intermediate age stars have indeed been found in circumnuclear rings around a number of Active Galactic Nuclei (AGN). One of these rings, with ~100pc radius is observed in the Seyfert 2 galaxy NGC1068, and is associated to an off-centered molecular ring, very similar to that observed in the Milky Way (MW). On the basis of an evolutionary scenario, we speculate that, in the MW, molecular gas has already accumulated within the inner ~100 pc and is already triggering the formation of new stars. A possible increase in the star-formation rate in the region will then be followed, tens of millions of years in the future, by the triggering of nuclear activity in Sgr A*.

description: Both disjunctive assertions and disjunctive questions can imply “not both”, i.e., that only one of the disjuncts is true. For assertions this is known to be part of what the speaker means (e.g., an implicature), whereas for questions this is instead a presupposition. This puzzle is challenging for predominant pragmatic and grammatical accounts of exhaustivity in the literature. This paper outlines a solution based on Attentional Pragmatics combined with (other) general pragmatic principles.

description: Acceleration of polarized electron~(positron) beams in a booster synchrotron may suffer from depolarization due to crossings of many spin depolarization resonances, which could limit its applications. We have studied the spin depolarization resonance structure of a 100~km scale booster lattice of the Circular Electron Positron Collider~(CEPC). The lattice has 8 arc regions with hundreds of FODO cells, interleaved with straight sections, which leads to a high periodicity. Our analysis shows the contributions to the strength of intrinsic and imperfection spin resonances add up coherently near the super strong resonances beyond 120 GeV, but mostly cancel out and result in generally weak resonance strengths at lower beam energies. Detailed simulations confirm that beam polarization can be mostly maintained in the fast acceleration to 45.6 GeV and 80 GeV, but severe depolarization may occur at even higher energies. This study suggests the possibility of acceleration of polarized electron~(positron) beams to ultra-high beam energies without the help of Siberian snakes, and supports injecting highly polarized beams into the collider rings as an attractive solution for resonant depolarization measurements and longitudinal polarized colliding beam experiments for future 100~km scale circular e$^{+}$e$^{-}$ colliders.

Not all gradable adjectives are vague – Experimental evidence from adults and children

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: This paper investigates whether absolute gradable adjectives such as clean show characteristics of vagueness, as do relative gradable adjectives such as big. We addressed this question by examining adults’ interpretation of the antonyms clean and dirty in a picture- selection task. Children between the ages of 3 and 5 were tested with the same task to see how early the interpretation pattern shown by the adults emerges in the course of acquisition. Our findings indicate that absolute gradable adjectives do not show characteristics of vagueness in either the adults or the children. Absolute gradable adjectives are interpreted as having a minimum or maximum standard of comparison, which is not context-sensitive, and they do not give rise to borderline cases.

We derive and apply Green's function-based formulation to compute the Josephson current in this system, as well as the local density of states in the junction. Our analysis of diagonal and off-diagonal components of the local density of states reveals the presence of triplet superconducting correlations in the MoS$_2$ monolayers and spin-polarized subgap (Andreev bound) states. Our formulation can be extended to other systems where atomistic details and large scales are needed to obtain accurate modeling of Josephson junction physics.

It proposes to derive the wide/narrow scope and related epistemic effects as implicatures by way of exhaustification with respect to alternatives associated with a disjunction/indefinite. A doxastic and an exhaustivity operator placed in the syntactic structure of a −hari disjunction/indefinite construction serve in deriving the implicatures, following the grammatical approach to derivation of implicatures (cf.

description: Introduction Previous studies have indicated that MetS is an independent risk factor for all-cause mortality and cardiovascular diseaserelated mortality. In Malaysia, data on risk of mortality related to MetS remains unavailable. Therefore, we conducted a retrospective cohort study to assess the association between MetS and all-cause and cardiovascular disease (CVD) mortality among Malaysians. Materials and Methods  Study population We analysed data from MyNCDS-1 2005/2006. MyNCDS1 is a nationwide, population-based baseline survey on noncommunicable diseases and its risk factors conducted in 2005- 2006. Baseline data Baseline data extracted from the MyNCDS-1 2005/2006 survey were participants’ sociodemographic characteristics (gender, ethnicity and age), lifestyle factors (physical activity, smoking status and alcohol consumption), anthropomorphic measurements (height, weight and waist circumference), blood pressure, and biochemical measurements (overnight fasting venous blood of lipid profile and glucose). Follow-up Participants of MyNCDS-1 were followed-up for approximately 13 years from March 2006 to December 2018. Data on mortality during this period were obtained by matching the survey participants’ identification number with records in the death registry administered by the National Registration Department of Malaysia. All deaths from CVD coded as ICD-10 I00 to ICD-10 I99 according to the International Statistical Classification of Diseases and Related Health Problems, tenth revision (ICD10)-version 2019 were classified as cardiovascular mortalities. Data analyses All statistical analyses were performed using IBM SPSS version 18.0 for Windows. The analyses took into account the complex survey design and unequal selection probabilities. Cox proportional-hazards regression model was applied to determine association between MetS and all-cause and CVD mortality adjusting for selected sociodemographic characteristics and health risk behaviours. Results [Refer to Poster]. Discussion / Conclusion Our data shows that presence of MetS was associated with 1.5 times risk of all-cause mortality and a 2-fold increase in risk of CVD mortality. Therefore, lifestyle modification and pharmacological treatment approaches might improve the individual components forming MetS and thereby reduce mortalities associated with MetS.

description: Traditional nearest points methods use all the samples in an image set to construct a single convex or affine hull model for classification. However, strong artificial features and noisy data may be generated from combinations of training samples when significant intra-class variations and/or noise occur in the image set. Existing multi-model approaches extract local models by clustering each image set individually only once, with fixed clusters used for matching with various image sets. This may not be optimal for discrimination, as undesirable environmental conditions (eg. illumination and pose variations) may result in the two closest clusters representing different characteristics of an object (eg. frontal face being compared to non-frontal face). To address the above problem, we propose a novel approach to enhance nearest points based methods by integrating affine/convex hull classification with an adapted multi-model approach. We first extract multiple local convex hulls from a query image set via maximum margin clustering to diminish the artificial variations and constrain the noise in local convex hulls. We then propose adaptive reference clustering (ARC) to constrain the clustering of each gallery image set by forcing the clusters to have resemblance to the clusters in the query image set. By applying ARC, noisy clusters in the query set can be discarded. Experiments on Honda, MoBo and ETH-80 datasets show that the proposed method outperforms single model approaches and other recent techniques, such as Sparse Approximated Nearest Points, Mutual Subspace Method and Manifold Discriminant Analysis.

The pressure jump across the elastic layer drives fluid flow through micro-channels that form at the interface between the layer and the substrate; these channels coalesce at discrete locations as the blister heals and eventually disappear at a lower critical radius. The spacing of the channel follows a simple scaling law that can be theoretically justified, and the kinetics of healing is rate limited by fluid flow, but with a non-trivial dependence on the substrate thickness that likely arises due to channelization. Our study is relevant to a variety of soft adhesion scenarios.

description: Time-reversal symmetry breaking allows for a rich set of magneto-transport properties related to electronic topology. Focusing on the magnetic Weyl semimetal Co$_3$Sn$_2$S$_2$, we prepared micro-ribbons and investigated their transverse and longitudinal transport properties from 100 K to 180 K in magnetic fields $μ_0 H$ up to 2T. We establish the presence of a magnetoresistance (MR) up to 1 % with a strong anisotropy depending the projection of $H$ on the easy-axis magnetization, which exceeds all other magnetoresistive effects. Based on detailed phenomenological modeling, we attribute the observed results with unexpected form of anisotropy to magnon MR resulting from magnon-electron coupling. Moreover, a similar angular dependence is also found in the transverse resistivity which we show to originate from the combination of ordinary Hall and anomalous Hall effects. Thus the interplay of magnetic and topological properties governs the magnetotransport features of this magnetic Weyl system.

description: In this work we set up a model Hamiltonian to study the excited state quantum dynamics of 1,1-difluoroethylene, a molecule that has equivalent atoms exchanged by a torsional symmetry operation leading to equivalent minima on the potential energy surface. In systems with many degrees of freedom where the minimum energy geometry is not unique, the ground state wavefunction will be delocalised among multiple minima. In this small test system, we probe the excited state dynamics considering localised (in a single minimum) and delocalised (spread over among multiple minima) wavefunctions and check whether this choice would influence the final outcome of the quantum dynamics calculations. Our molecular Hamiltonian comprises seven electronic states, including valence and Rydberg states, computed with the MS-CASPT2 method and projected onto the vibrational coordinates of the twelve normal modes of 1,1-difluoroethylene in its vibrational ground state. This Hamiltonian has been symmetrised along the torsional degree of freedom to make both minima completely equivalent and the model is supported by the excellent agreement with the experimental absorption spectrum. Quantum dynamics results show that the different initial conditions studied do not appreciably affect the excited state populations or the absorption spectrum when the dynamics is simulated assuming a delta pulse excitation.

"Just" don’t ask: Exclusives and potential questions
Creators: name: Warstadt, Alex
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2020

description: The English exclusive just is not synonymous with other exclusives such as only in sentences like Sometimes, bad things just/only happen. I give a new analysis of just which explains this and other puzzling readings of just observed in earlier work (e.g. Wiegand, 2016; Beltrama, 2018). I argue that just excludes alternatives derived from a potential question, or possible future QUD, in the sense of Onea (2016). This new perspective makes it possible to give the first unified account of these non-canonical exclusive readings of just, and provides evidence that the semantics of lexical items can be sensitive to possible futures of the discourse.

description: The global increase in demand for wood products, calls for a more sustainable management of forests to optimize both the production of wood and the conservation of forest biodiversity. In this paper, we evaluate the status and future trends of forest birds in Central European forests, assuming different forest management scenarios that to a varying degree respond to the demand for wood production. To this end, we use niche models (Boosted Regression Trees and Generalized Linear Models) to model the responses of 15 forest bird species to predictors related to forest stand (e.g., stand volume of specific tree species) and landscape structure (e.g., percentage cover), and to climate (bioclimatic variables). We then define five distinct forest management scenarios, ranging from set-aside to productivity-driven scenarios, project them 100 years into the future, and apply our niche models into these scenarios to assess the birds’ responses to different forest management alternatives. Our models show that the species’ responses to management vary reflecting differences in their ecological niches, and consequently, no single management practice can benefit all species if applied across the whole landscape. Thus, we conclude that in order to promote the overall forest bird species richness in the study region, it is necessary to manage the forests in a multi-functional way, e.g., by spatially optimizing the management practices in the landscape.
New signals for singlet Higgs and vector-like quarks at the LHC

description: We consider an extension of the Standard Model involving a singlet Higgs and down type vector-like quarks in the light of the current LHC Higgs data. For a good range of the parameters of the Higgs potential, and a mass range for the heavy vector-like quark, we find that the singlet heavy Higgs arising from the production and decay of the vector-like quarks give rise to (2b~4t) signal. The subsequent decay of the top quarks to $b W^{+}$ give rise to a final state with six b quarks, two same-sign charged leptons and missing transverse momenta with observable cross-sections at the 14 TeV run of the Large Hadron Collider. The Standard Model background for such a final state is practically negligible.

Facilitators on networks reveal the optimal interplay between information exchange and reciprocity

description: Reciprocity is firmly established as an important mechanism that promotes cooperation. An efficient information exchange is likewise important, especially on structured populations, where interactions between players are limited. Motivated by these two facts, we explore the role of facilitators in social dilemmas on networks. Facilitators are here mirrors to their neighbors -- they cooperate with cooperators and defect with defectors -- but they do not participate in the exchange of strategies. As such, in addition to introducing direct reciprocity, they also obstruct information exchange. In well-mixed populations, facilitators favor the replacement and invasion of defection by cooperation as long as their number exceeds a critical value. In structured populations, on the other hand, there exists a delicate balance between the benefits of reciprocity and the deterioration of information exchange. Extensive Monte Carlo simulations of social dilemmas on various interaction networks reveal that there exists an optimal interplay between reciprocity and information exchange, which sets in only when a small number of facilitators occupies the main hubs of the scale-free network. The drawbacks of missing cooperative hubs are more than compensated by reciprocity and, at the same time, the compromised information exchange is routed via the auxiliary hubs with only marginal losses in effectivity. These results indicate that it is not always optimal for the main hubs to become ''leaders of the masses'', but rather to exploit their highly connected state to promote tit-for-tat-like behavior.

The interaction of just with modified scalar predicates

description: It remains an open question whether the range of uses associated with the English particle just can be analyzed uniformly. Much previous literature has focused on the exclusive uses of just with relatively little attention paid to its non-exclusive uses. We provide an analysis for the approximative use of just, which occurs with modified scalar predicates in sentences like Mary is just taller than John or Mary is just as tall as John. We argue that this use of just has two effects: (1) it conveys that its prejacent is true at a maximal level of precision, and (2) it conveys that its prejacent is not true at any lower level of precision that would make a stronger claim. On this analysis, the approximative use of just is similar to the exclusive use in that the effect in both cases is that stronger alternatives to the prejacent are ruled out.

Josephson effects between the Kitaev ladder superconductors

description: The two-leg ladder system consisting of the Kitaev chains is known to exhibit a richer phase diagram than that of the single chain. We theoretically investigate the variety of the Josephson effects between the ladder systems. We consider the Josephson phase difference $θ$ between these two ladder systems as well as the phase difference $ϕ$ between the parallel chains in each ladder system. The total energy of the junction at $T = 0$ is calculated by a numerical diagonalization method as functions of $θ$, $ϕ$, and also a transverse hopping $t_{\perp}$ in the ladders. We find that, by controlling $t_{\perp}$ and $ϕ$, the junction exhibits not only the fractional Josephson effect for the phase difference $θ$, but also the usual 0-junction and even $π$-junction properties.

description: For a fixed 2-block Springer fiber, we describe the structure of its irreducible components and their relation to the Bialynicki-Birula paving, following work of Fung. That is, we consider the space of complete flags in C^n preserved by a fixed nilpotent matrix with 2 Jordan blocks, and study the action of diagonal matrices commuting with our fixed nilpotent. In particular, we describe the structure of each component, its set of torus fixed points, and prove a conjecture of Fung describing the intersection of any pair. Then we define a convolution algebra structure on the direct sum of the cohomologies of pairwise intersections of irreducible components and closures of C^*-attracting sets (that is, Bialynicki-Birula cells), and show this is isomorphic to a generalization of the arc algebra of Khovanov defined by the first author. We investigate the connection of this algebra to Cautis & Kamnitzer's recent work on link homology via coherent sheaves and suggest directions for future research.
