description: A meme is a form of media that spreads an idea or emotion across the internet. As posting meme has become a new form of communication of the web, due to the multimodal nature of memes, postings of hateful memes or related events like trolling, cyberbullying are increasing day by day. Hate speech, offensive content and aggression content detection have been extensively explored in a single modality such as text or image. However, combining two modalities to detect offensive content is still a developing area. Memes make it even more challenging since they express humour and sarcasm in an implicit way, because of which the meme may not be offensive if we only consider the text or the image. Therefore, it is necessary to combine both modalities to identify whether a given meme is offensive or not. Since there was no publicly available dataset for multimodal offensive meme content detection, we leveraged the memes related to the 2016 U.S. presidential election and created the MultiOFF multimodal meme dataset for offensive content detection dataset. We subsequently developed a classifier for this task using the MultiOFF dataset. We use an early fusion technique to combine the image and text modality and compare it with a text- and an image-only baseline to investigate its effectiveness. Our results show improvements in terms of Precision, Recall, and F-Score. The code and dataset for this paper is published in https://github.com/bharathichezhiyan/ Multimodal-Meme-Classification-Identifying-Offensive-Content-in-Image-and-Text

Gli Istituti Di Istruzione Superiore (IIS) sono sempre più chiamati a comprovare il loro impatto sulla società in termini di inclusività e sostenibilità sociale, come priorità nel perseguimento della “Terza Missione” (TM). Tra le varie sfide da affrontare si annovera la richiesta di garantire l’inclusività dei rifugiati. Tuttavia, il modo in cui il personale amministrativo e docente attua tale cambiamento all’interno dell’organizzazione per raggiungere gli obiettivi della Terza Missione è poco studiato. Questo studio esplora le politiche e le pratiche a sostegno del riconoscimento delle qualifiche dei rifugiati per l'accesso all'istruzione superiore in Italia, e in particolare il Passaporto europeo di qualificazione per rifugiati (EQPR) come strumento per perseguire la Terza Missione dell'università. Adottando un approccio teorico basato sul sense-making (creazione di senso), lo studio dimostra che il ruolo individuale del personale nel favorire il cambiamento organizzativo dipende da un approccio “emergente” al cambiamento organizzativo e da fattori interni, come percezioni ed esperienze individuali. Questo studio contribuisce alla letteratura del settore, mettendo in luce  aspetti contraddittori nel perseguimento della TM da parte degli Istituti di Istruzione Superiore, dando evidenza dell’interazione tra diverse dimensioni e processi radicati di sense-making.
Dispersal in Phytoseiulus persimilis Athias-Henriot (Acarina: Phytoseiidae) and its importance to biological control programs
Creators: name: Gadsby, Margaret Carol
Publisher: name: University of British Columbia
Year: 2010

description: The dispersal of Phytoseiulus persimilis Athias-Henriot, a predatory phytoseiid mite used in biological control of the phytophagous two-spotted spider mite, Tetranychus urticae Koch, has been largely ignored to the detriment of control programs. In this thesis, three aspects of behaviour were studied over the developmental period of the predator and related to dispersal. Two predictive indices for dispersal were derived. Dispersive tendency was induced in adult female predators by confining them at high density (10 per capillary tube) and starving them for 24 hours. Dispersers were characterized behaviourally. Dispersers were typically geopositive and displayed an ability and strong tendency to distinguish edges and follow them. Dispersers moved at speeds three times greater than normal individuals, and were less efficient predators. Dispersers moved onto a novel substrate five times faster than normal individuals. Induced dispersal behaviour persisted for 40-46 hours after release, even when predators were provided with ample prey. When released onto infested bean and cucumber plants, dispersive mites exercised poorer control on the pest population than non-dispersive predators. Prey numbers were greater and plant damage was more severe and less localized. On the young leaves of cucumber plants, predator egg placement was not harmonious with prey distribution. The potentially disruptive affect of dispersal on control programs is discussed. A re-evaluation of predatory efficiency in the light of this result is recommended. The need to assess the dispersive tendency of stock populations of the predator and eliminate those which are "too" prone to disperse is stressed. The impact of standard pre-release methods which apparently induce dispersal on greenhouse control programs is also discussed. The need to assess stocks which form the basis for organophosphate-resistance selection programs is also addressed. Cannibalism, inter-male aggression, substrate preference, and oviposition site selection in P. persimilis are also discussed.

description: We have constructed a systematic low-energy effective theory for hole- and electron-doped antiferromagnets, where holes reside in momentum space pockets centered at $(\pm\fracπ{2a},\pm\fracπ{2a})$ and where electrons live in pockets centered at $(\fracπ{a},0)$ or $(0,\fracπ{a})$. The effective theory is used to investigate the magnon-mediated binding between two holes or two electrons in an otherwise undoped system. We derive the one-magnon exchange potential from the effective theory and then solve the corresponding two-quasiparticle Schrödinger equation. As a result, we find bound state wave functions that resemble $d_{x^2-y^2}$-like or $d_{xy}$-like symmetry. We also study possible ground states of lightly doped antiferromagnets.

description: We find that the spin susceptibility of a two-dimensional electron system with valley degeneracy does not grow critically at low densities, at variance with experimental results [A. Shashkin et al., Phys. Rev. Lett. 96, 036403 (2006)]. We ascribe this apparent discrepancy to the weak disorder present in experimental samples. Our prediction is obtained from accurate correlation energies computed with state of-the-art diffusion Monte Carlo simulations and fitted with an analytical expression which also provides a local spin density functional for the system under investigation.

Its modular design makes NuRadioMC suitable for use with a range of past, current and future detectors. In addition, the recent deployment
of a complete documentation as well as a pip release make NuRadioMC relatively easy to learn and use. Here, we outline the features currently available and under development in NuRadioMC, with a focus on its usage to simulate and study in-ice radio neutrino detectors.

Oligarchic planetesimal accretion and giant planet formation

description: Aims. In the context of the core instability model, we present calculations of in situ giant planet formation. The oligarchic growth regime of solid protoplanets is the model adopted for the growth of the core. Methods. The full differential equations of giant planet formation were numerically solved with an adaptation of a Henyey-type code. The planetesimals accretion rate was coupled in a self-consistent way to the envelope's evolution. Results. We performed several simulations for the formation of a Jupiter-like object by assuming various surface densities for the protoplanetary disc and two different sizes for the accreted planetesimals. We find that the atmospheric gas drag gives rise to a major enhancement on the effective capture radius of the protoplanet, thus leading to an average timescale reduction of 30% -- 55% and ultimately to an increase by a factor of 2 of the final mass of solids accreted as compared to the situation in which drag effects are neglected. With regard to the size of accreted planetesimals, we find that for a swarm of planetesimals having a radius of 10 km, the formation time is a factor 2 to 3 shorter than that of planetesimals of 100 km, the factor depending on the surface density of the nebula. Moreover, planetesimal size does not seem to have a significant impact on the final mass of the core.

The results are in excellent agreement with exact diagonalization on small clusters and give reliable results even for high densities, where the usual ladder approximation breaks down. We apply the theory to the computation of antibound states relevant for Auger spectroscopy and cold atom physics. A special bonus of the theory is its computational simplicity.

In particular, we report on the excitability regime that cavity solitons exhibits which is emergent property since the system is not locally excitable. The resulting scenario differs in an important way from the case of a purely homogeneous pump and now two different excitable regimes, both Class I, are shown. The whole scenario is presented and discussed, showing that it is organized by three codimension-2 points. Moreover, the localized beam can be used to control important features, such as the excitable threshold, improving the possibilities for the experimental observation of this phenomenon.

description: One-dimensional (1D) van der Waals heterostructures based on carbon nanotube templates are raising a lot of excitement due to the possibility of creating new optical and electronic properties, by either confining molecules inside their hollow core or by adding layers on the outside of the nanotube. In contrast to their 2D analogues, where the number of layers, atomic type and relative orientation of the constituting layers are the main parameters defining physical properties, 1D heterostructures provide an additional degree of freedom, i.e. their specific diameter and chiral structure, for engineering their characteristics. This review discusses the current state-of-the-art in synthesizing 1D heterostructures, in particular focusing on their resulting optical properties, and details the vast parameter space that can be used to design heterostructures with custom-built properties that can be integrated into a large variety of applications. The review starts from describing the effects of van der Waals coupling on the properties of the simplest and best-studied 1D heterostructure, namely a double-wall carbon nanotube, then considers heterostructures built from the inside and the outside, which all use a nanotube as a template, and, finally, provides an outlook for the future of this research field.

description: We present a search for star-forming satellite galaxies that are close enough to their parent galaxies to be considered analogues of the Magellanic Clouds. Our search technique relied on the detection of the satellites in continuum-subtracted narrow-band H alpha imaging of the central galaxies, which removes most of the background and foreground line-of-sight companions, thus giving a high probability that we are detecting true satellites. The search was performed for 119 central galaxies at distances between 20 and 40 Mpc, although spatial incompleteness means that we have effectively searched 53 full satellite-containing volumes. We find only 9 probable star-forming satellites, around 9 different central galaxies, and 2 possible satellites. After incompleteness correction, this is equivalent to 0.17/0.21 satellites per central galaxy. The Small Magellanic Cloud is just below the median values of both star formation rate and R-band luminosity of the 9 probable satellites. The Large Magellanic Cloud, however, has a higher R-band luminosity than any of the 9 and is only exceeded in star formation rate by the one satellite that appears to be undergoing a tidally-induced starburst. Thus the Milky Way appears to be quite unusual, both in having two star-forming satellite galaxies and in the high luminosity of the Large Magellanic Cloud.

description: We offer the parameter, interpreted as the "chemical potential", which is sensitive to the first order phase transition: it must decrease with number of evaporating (produced) particles (hadrons) if the (interacting hadron or/and QCD plasma) medium is boiling and it increase if no phase transition occur. The main part of the paper is devoted to the question: how one can measure the "chemical potential" in the hadron inelastic processes. Our definition of this parameter is quite general but assumes that the hadron multiplicity is sufficiently large. The simple transparent phenomenological lattice gas model is considered for sake of clarity only.

Fig. 96; Tables 93–94
Diagnosis
Species of Weyerella with a conch reaching 25 mm diameter. Conch at 15 mm dm extremely discoidal, subevolute (ww/dm ~0.32; uw/dm ~0.35). Whorl profile at 15 mm dm weakly compressed (ww/wh ~0.85); coiling rate very low (WER ~1.45). Venter continuously rounded, umbilical margin narrowly rounded. Shell nearly smooth; without constrictions on the shell surface.
Etymology
From the Latin ‘ lenis ’ = ‘gentle’, referring to the very weak ornament.
Material examined
Holotype
GERMANY • Rhenish Mountains, Oberrödinghausen, railway cutting; Hangenberg Limestone, bed 2a; Weyer 1993–1994 Coll.; illustrated in Fig. 96A; MB.C.31192.
Paratype
GERMANY • 1 specimen; Rhenish Mountains, Oberrödinghausen, railway cutting; Hangenberg Limestone, bed 2; Vöhringer Coll.; GPIT-PV-63929.
Description
Holotype MB.C.31192 is an incomplete specimen with approximately 15 mm conch diameter (Fig. 96A). It is thinly discoidal and subevolute (ww/dm = 0.34; uw/dm = 0.36); the whorl profile is weakly compressed (ww/dm = 0.91) with slightly flattened, convergent flanks and a continuously rounded venter. The coiling rate is low (WER = 1.44). The shell surface appears to be completely smooth with the exception of a few barely discernible radial folds that extend backwards on the flank.
Paratype GPIT-PV-63929 had already been sectioned by Vöhringer, but not illustrated. It allows the study of all whorls up to a conch diameter of 9 mm (Fig. 96B). The whorl profile is kidney-shaped up to 5 mm conch diameter, thereafter it becomes C-shaped with increasing enclosure of the preceding whorl. The aperture is low in all stages; the coiling rate is always close to 1.50.
Remarks
Weyerella lenis sp. nov. differs from all the other species of the genus Weyerella in the combination of the very slender conch, the low coiling rate (WER ~1.50) and the smooth shell.

description: Graphene possesses unique features that make it attractive for nanotechnology. Functional devices often require combination of several materials with specific functions, and graphene-polymer composites are one of them. Herein, we report on the preparation of PEDOT:Graphene bilayers by in situ polymerization of EDOT on covalently functionalized graphene. The polymerization proceeds exclusively on the grafted graphene, and patterned structures with high spatial resolution down to 3 μm could have been prepared. The composite exhibits enhanced efficiency of electrochemical doping compared to pristine graphene, unsymmetrical transport characteristic with very good hole-transporting properties and efficient electronic communication between the two materials.

description: A key problem in protoplanetary disc evolution is understanding the efficiency of dust radial drift. This process makes the observed dust disc sizes shrink on relatively short timescales, implying that discs started much larger than what we see now. In this paper we use an independent constraint, the gas radius (as probed by CO rotational emission), to test disc evolution models. In particular, we consider the ratio between the dust and gas radius, $R_{\rm CO}/R_{\rm dust}$. We model the time evolution of protoplanetary discs under the influence of viscous evolution, grain growth, and radial drift. Then, using the radiative transfer code RADMC with approximate chemistry, we compute the dust and gas radii of the models and investigate how $R_{\rm CO}/R_{\rm dust}$ evolves. Our main finding is that, for a broad range of values of disc mass, initial radius, and viscosity, $R_{\rm CO}/R_{\rm dust}$ becomes large (>5) after only a short time (<1 Myr) due to radial drift. This is at odds with measurements in young star forming regions such as Lupus, which find much smaller values, implying that dust radial drift is too efficient in these models. Substructures, commonly invoked to stop radial drift in large, bright discs, must then be present, although currently unresolved, in most discs.

description: Correct defect quantification in graphene samples is crucial both for fundamental and applied re-search. Raman spectroscopy represents the most widely used tool to identify defects in graphene. However, despite its extreme importance the relation between the Raman features and the amount of defects in multilayered graphene samples has not been experimentally verified. In this study we intentionally created defects in single layer graphene, turbostratic bilayer graphene and Bernal stacked bilayer graphene by oxygen plasma. By employing isotopic labelling, our study reveals substantial differences of the effects of plasma treatment on individual layers in bilayer graphene with different stacking orders. In addition Raman spectroscopy evidences scattering of phonons in the bottom layer by defects in the top layer for Bernal-stacked samples, which can in general lead to overestimation of the number of defects by as much as a factor of two.

description: Study the behaviour and the evolution of the cosmological field equations in an homogeneous and anisotropic spacetime with two scalar fields coupled in the kinetic term. Specifically, the kinetic energy for the scalar field Lagrangian is that of the Chiral model and defines a two-dimensional maximally symmetric space with negative curvature. For the background space we assume the locally rotational spacetime which describes the Bianchi I, the Bianchi III and the Kantowski-Sachs anisotropic spaces. We work on the $H$% -normalization and we investigate the stationary points and their stability. For the exponential potential we find a new exact solution which describes an anisotropic inflationary solution. The anisotropic inflation is always unstable, while future attractors are the scaling inflationary solution or the hyperbolic inflation. For scalar field potential different from the exponential, the de Sitter universe exists.

Tra le varie sfide da affrontare si annovera la richiesta di garantire l’inclusività dei rifugiati. Tuttavia, il modo in cui il personale amministrativo e docente attua tale cambiamento all’interno dell’organizzazione per raggiungere gli obiettivi della Terza Missione è poco studiato. Questo studio esplora le politiche e le pratiche a sostegno del riconoscimento delle qualifiche dei rifugiati per l'accesso all'istruzione superiore in Italia, e in particolare il Passaporto europeo di qualificazione per rifugiati (EQPR) come strumento per perseguire la Terza Missione dell'università. Adottando un approccio teorico basato sul sense-making (creazione di senso), lo studio dimostra che il ruolo individuale del personale nel favorire il cambiamento organizzativo dipende da un approccio “emergente” al cambiamento organizzativo e da fattori interni, come percezioni ed esperienze individuali. Questo studio contribuisce alla letteratura del settore, mettendo in luce  aspetti contraddittori nel perseguimento della TM da parte degli Istituti di Istruzione Superiore, dando evidenza dell’interazione tra diverse dimensioni e processi radicati di sense-making.
What happens to geometric phase when spin-orbit interactions lift band degeneracy?

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: Spin-orbit interaction lifts accidental band degeneracy. The geometric phase gamma(C)=pi for circuits surrounding a line of such degeneracy cannot survive completely unchanged. The change depends on how the spin is fixed during adiabatic evolution. For spin fixed along the internal spin-orbit field, gamma(C) decreases to zero as the circuit collapses around the line of lifted degeneracy. For spin fixed along a perpendicular axis, the conical intersection persists and gamma(C)=pi is unchanged.

A simulation modeling technique for projecting future extened care bed requirements
Creators: name: Kallstrom, Elizabeth
Publisher: name: University of British Columbia

description: A simulation model was developed for the Greater Vancouver Regional Hospital District for the purpose of projecting future Extended Care Bed requirements. The model utilizes data which are not usually incorporated in such projections but which are critical for ensuring maximum accuracy of the projections. Length of stay and length of wait information are two such items. In 1980, the average length of stay in an Extended Care Unit was found to be 30.3 months and the average length of wait for admission to a unit was approximately 9 months within the G.V.R.H.D. The increase in the numbers of elderly in this population was projected to be 16,500 persons from 1981 to 1986 or a percentile increase from 11.7% of the total population to 12.4%. In order to maintain a constant waiting period of 9 months, an additional 300 Extended Care beds were estimated to be required by 1986. The length of the waiting list, or the queue, would increase slightly under such conditions. An additional 2,200 beds would be required to eliminate the waiting period completely and to deplete the queue. The effect of reducing the application rate was also investigated. Waiting period and queue length were very sensitive to such a change as evidenced by sharp reductions in both. The opposite was true when the application rate was increased; both waiting time and queue length increased considerably. The effects of varying the proportion of activated on-hold applicants and the time interval for additions of new beds were also investigated. The use of this model in forecasting Extended Care Bed requirements in the short term is discussed with a view to comparing these projection results to those of other forecasting methodologies employed in Canadian Metro regions. Future data requirements of the model are also discussed.

Self-diffusion in a monatomic glassforming liquid embedded in the hyperbolic plane

description: We study by Molecular Dynamics simulation the slowing down of particle motion in a two-dimensional monatomic model: a Lennard-Jones liquid on the hyperbolic plane. The negative curvature of the embedding space frustrates the long-range extension of the local hexagonal order. As a result, the liquid avoids crystallization and forms a glass. We show that, as temperature decreases, the single particle motion displays the canonical features seen in real glassforming liquids: the emergence of a "plateau" at intermediate times in the mean square displacement and a decoupling between the local relaxation time and the (hyperbolic) diffusion constant.

description: GSN 069 is an ultra-soft X-ray active galactic nucleus that previously exhibited a huge X-ray outburst and a subsequent long-term decay. It has recently presented X-ray quasi-periodic eruptions (QPEs). We report the detection of strong nitrogen lines but weak or undetectable carbon lines in its far ultraviolet spectrum. With a detailed photoionization model, we use the C IV/N IV] ratio and other ratios between nitrogen lines to constrain the [C/N] abundance of GSN 069 to be from -3.33 to -1.91. We argue that a partially disrupted red giant star can naturally explain the abnormal C/N abundance in the UV spectrum, while the surviving core orbiting the black hole might produce the QPEs.

A method for characterization of coherent backgrounds in real time and its application in gravitational wave data analysis

description: Many experiments, and in particular gravitational wave detectors, produce continuous streams of data whose frequency representations contain discrete, relatively narrowband coherent features at high amplitude. We discuss the application of digital Fourier transforms (DFTs) to characterization of these features, hereafter frequently referred to as lines. Application of DFTs to continuously produced time domain data are achieved through an algorithm hereafter referred to as EFC for efficient time-domain determination of the Fourier coefficients of a data set. We first define EFC and discuss parameters relating to the algorithm that determine its properties and action on the data. In gravitational wave interferometers, these lines are commonly due to parasitic sources of coherent background interference coupling into the instrument. Using GEO 600 data, we next demonstrate that time domain subtraction of lines can proceed without detrimental effects either on features at frequencies separated from that of the subtracted line, or on features at the frequency of the line but having different stationarity properties.

description: We propose a new, conjectural recursion solution for Hurwitz numbers at all genera. This conjecture is based on recent progress in solving type B topological string theory on the mirrors of toric Calabi-Yau manifolds, which we briefly review to provide some background for our conjecture. We show in particular how this B-model solution, combined with mirror symmetry for the one-leg, framed topological vertex, leads to a recursion relation for Hodge integrals with three Hodge class insertions. Our conjecture in Hurwitz theory follows from this recursion for the framed vertex in the limit of infinite framing.

A Better Way to Reconstruct Dark Energy Models ?

description: To reconstruct dark energy models the redshift $z_{eq}$, marking the end of radiation era and the beginning of matter-dominated era, can play a role as important as $z_{t}$, the redshift at which deceleration parameter experiences a signature flip. To implement the idea we propose a variable equation of state for matter that can bring a smooth transition from radiation to matter-dominated era in a single model. A popular $Λ\propto ρ$ dark energy model is chosen for demonstration but found to be unacceptable. An alternative $Λ\propto ρa^{3}$ model is proposed and found to be more close to observation.

description: We report the discovery of a high CO(J=3-2)/CO(J=1-0) ratio gas with an arc-like distribution (``high-ratio gas arc'') surrounding the central star cluster of the supergiant HII region NGC 604 in the nearby spiral galaxy M 33, based on multi-J CO observations of a 5' $\times$ 5' region of NGC 604 conducted using the ASTE 10-m and NRO 45-m telescopes. The discovered ``high-ratio gas arc'' extends to the south-east to north-west direction with a size of $\sim$ 200 pc. The western part of the high-ratio gas arc closely coincides well with the shells of the HII regions traced by H$α$ and radio continuum peaks. The CO(J=3-2)/CO(J=1-0) ratio, R_{3-2/1-0}, ranges between 0.3 and 1.2 in the observed region, and the R_{3-2/1-0} values of the high-ratio gas arc are around or higher than unity, indicating very warm (T_kin > 60 K) and dense (n(H_2) > 10^{3-4} cm^{-3}) conditions of the high-ratio gas arc. We suggest that the dense gas formation and second-generation star formation occur in the surrounding gas compressed by the stellar wind and/or supernova of the first-generation stars of NGC 604, i.e., the central star cluster of NGC 604.

description: With YouTube's growing importance as a news platform, its recommendation system came under increased scrutiny. Recognizing YouTube's recommendation system as a broadcaster of media, we explore the applicability of laws that require broadcasters to give important political, ideological, and social groups adequate opportunity to express themselves in the broadcasted program of the service. We present audits as an important tool to enforce such laws and to ensure that a system operates in the public's interest. To examine whether YouTube is enacting certain biases, we collected video recommendations about political topics by following chains of ten recommendations per video. Our findings suggest that YouTube's recommendation system is enacting important biases. We find that YouTube is recommending increasingly popular but topically unrelated videos. The sadness evoked by the recommended videos decreases while the happiness increases. We discuss the strong popularity bias we identified and analyze the link between the popularity of content and emotions. We also discuss how audits empower researchers and civic hackers to monitor complex machine learning (ML)-based systems like YouTube's recommendation system.
