description: We measure the magnetic field dependence of the frequency and damping time for the radial breathing mode of an optically trapped, Fermi gas of $^6$Li atoms near a Feshbach resonance. The measurements address the apparent discrepancy between the results of Kinast et al., [Phys. Rev. Lett. {\bf 92}, 150402 (2004)] and those of Bartenstein et al., [Phys. Rev. Lett. {\bf 92}, 203201 (2004)]. Over the range of magnetic field from 770 G to 910 G, the measurements confirm the results of Kinast et al. Close to resonance, the measured frequencies are in excellent agreement with predictions for a unitary hydrodynamic gas. At a field of 925 G, the measured frequency begins to decrease below predictions. For fields near 1080 G, we observe a breakdown of hydrodynamic behavior, which is manifested by a sharp increase in frequency and damping rate. The observed breakdown is in qualitative agreement with the sharp transition observed by Bartenstein et al., at 910 G.

description: We examine the accuracy of a common technique for estimating the start time of solar energetic particle injection based on a linear fit to the observed onset time versus 1/(particle velocity). This is based on a concept that the first arriving particles move directly along the magnetic field with no scattering. We check this by performing numerical simulations of the transport of solar protons between 2 and 2000 MeV from the Sun to the Earth, for several assumptions regarding interplanetary scattering and the duration of particle injection, and analyzing the results using the inverse velocity fit. We find that in most cases, the onset times align close to a straight line as a function of inverse velocity. Despite this, the estimated injection time can be in error by several minutes. Also, the estimated path length can deviate greatly from the actual path length along the interplanetary magnetic field. The major difference between the estimated and actual path lengths implies that the first arriving particles cannot be viewed as moving directly along the interplanetary magnetic field.

description: Artikkelissa "Arkkitehtonisen synnyn genre – Arkkitehdin evoluutiopolku" arvioidaan arkkitehdin sukupuolittumista, maskuliinia ja feminiiniä arkkitehdissa.
Arkkitehdilla on lapsuus ja historia, jotka valmistavat hänet uralle. Ahkeruus ja siviilirohkeus ovat merkittäviä tavoitellessaan arkkitehtonisuutta.
Ihminen (yleensä) ymmärtää arkkitehtuuria, mutta hän poiskouluttautuu tästä ymmärryksestä yhteiskunnan, kulttuurin, typerryttävän vuorovaikutuksen ja oman arkuuden, laiskuuden ja saamattomuuden vuoksi. Vain harva arkkitehti pystyy täyttämään arkkitehtuurin vaatimukset arkhi- ja tekton -käsitteiden, siis ylimmän taidon tasolla. Käsitteet arkhi [αρχι- (archi-)] ja tekton [τεκτων (tekton)] määrittelevät ylimmän rakentamistaidon niin idean, tarkoitteiden, suunnittelun kuin rakentamisenkin osilta.
Lopuksi laaditaan arkkitehdin evoluutiopolku opiskelusta ammattiin ja kuolemaan. Naiselle ja miehelle löydetään hieman poikkeavat reitit ja matka. Kaaviot selventävät maskuliin ja feminiinin osuuksia miehessä ja naisessa, ja arkkitehtdin evoluutiopolussa ovat esimerkkeinä Louis Kahn, Alvar Aalto, Frank Lloyd Wright, Le Corbusier, Reima Pietilä ja Antonio Gaudi elämän, uran ja teostensa kautta.

description: We study scalar-linear and vector-linear solutions of the generalized combination network. We derive new upper and lower bounds on the maximum number of nodes in the middle layer, depending on the network parameters and the alphabet size. These bounds improve and extend the parameter range of known bounds. Using these new bounds we present a lower bound and an upper bound on the gap in the alphabet size between optimal scalar-linear and optimal vector-linear network coding solutions. For a fixed network structure, while varying the number of middle-layer nodes $r$, the asymptotic behavior of the upper and lower bounds shows that the gap is in $Θ(\log(r))$.

description: This paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy-efficiency in buildings. The empirical analysis focuses on three main types of policy instruments, namely regulatory energy standards in buildings codes, energy taxes as captured by energy prices and specific governmental energy R&D expenditures. Technological innovation is measured using patent counts for specific technologies related to energy-efficiency in buildings (e.g. insulation, high-efficiency boilers, energy-saving lightings). The estimates for seven European countries over the 1989-2004 period imply that a strengthening of 10% of the minimum insulation standards for walls would increase the likelihood to file additional patents by about 3%. In contrast, energy prices have no significant effect on the likelihood to patent. Governmental energy R&D support has a small positive significant effect on patenting activities.

description: Battery storage is expected to play a crucial role in the low-carbon transformation of energy systems. The deployment of battery storage in the power gird, however, is currently severely limited by its low economic viability, which results from not only high capital costs but also the lack of flexible and efficient utilization schemes and business models. Making utility-scale battery storage portable through trucking unlocks its capability to provide various on-demand services. We introduce the potential applications of utility-scale portable energy storage and investigate its economics in California using a spatiotemporal decision model that determines the optimal operation and transportation schedules of portable storage. We show that mobilizing energy storage can increase its life-cycle revenues by 70% in some areas and improve renewable energy integration by relieving local transmission congestion. The life-cycle revenue of spatiotemporal arbitrage can fully compensate for the costs of portable energy storage system in several regions in California, including San Diego and the San Francisco Bay Area.

Switching superconductivity in S/F bilayers by multiple-domain structures

description: We consider the effect of a multiple magnetic domain structure in a superconductor/ferromagnet bilayer, modeled by a ferromagnetic layer with a rotating magnetic moment. The domain walls in this model are of equal size as the domains, and are of Neel type. We study the superconducting critical temperature as a function of the rotation wavelength of the magnetic moment. The critical temperature of the bilayer is found to be always enhanced by the domain structure, and exhibits an interesting reentrant behavior. We suggest that this effect can be used for a new device where superconductivity may be controlled by the domain structure of the magnetic layer.

description: The effective DNA-DNA interaction force is calculated by computer simulations with explicit tetravalent counterions and monovalent salt. For overcharged DNA molecules, the interaction force shows a double-minimum structure. The positions and depths of these minima are regulated by the counterion density in the bulk. Using two-dimensional lattice sum and free energy perturbation theories, the coexisting phases for DNA bundles are calculated. A DNA-condensation and redissolution transition and a stable mesocrystal with an intermediate lattice constant for high counterion concentration are obtained.

description: The orbital decay of a perturber within a larger system plays a key role in the dynamics of many astrophysical systems -- from nuclear star clusters or globular clusters in galaxies, to massive black holes in galactic nuclei, to dwarf galaxy satellites within the dark matter halos of more massive galaxies. For many decades, there have been various attempts to determine the underlying physics and time-scales of the drag mechanism, ranging from the local dynamical friction approach to descriptions based on the back-reaction of global modes induced in the background system. We present ultra-high-resolution $N$-body simulations of massive satellites orbiting a Milky Way-like galaxy (with $> 10^8$ particles), that appear to capture both the local "wake" and the global "mode" induced in the primary halo. We address directly the mechanism of orbital decay from the combined action of local and global perturbations and specifically analyze where the bulk of the torque originates.

From theory to practice : the Canadian courts and the adjudication of (post-modern) identities
Creators: name: McGregor, Cara
Publisher: name: University of British Columbia
Year: 2009

description: In this work, I introduce the concept of identity, outline its importance, and argue in favour of a post-modem conception of identity, underpinned by the principles of contestation, anti-essentialism and hybridity. This notion of identity, which is supported by both theoretical and case evidence, is in tension with the practices of the courts, which are often asked to make determinations that impact identities. The court's conventions and practices privilege a modernist notion of identity; given these restrictions, how are post-modern identities, such as the Metis, to be recognized? Using the case ofK v. Powley, / explore the possibilities and openings for a post-modern concept of identity to be realized in the courts. While there are conflicts and restrictions, judges, courts and the law demonstrate sufficient flexibility to allow for post-modern principles to be realized. I conclude by arguing that the courts should go further in developing a post-modern conception of identity in their work, and explore the issues and implications of doing so. I also reflect on the broader question this work presents, namely the role of the law and the possibilities for change therein.

description: Measuring the stellar rotation of one of the components in eclipsing binaries (EBs) or planetary systems is a challenging task. The difficulty is mainly due to the complexity of analyzing, in the same light curve, the signal from the stellar rotation mixed with the transit signal of a stellar or sub-stellar companion, like a brown dwarf or planet. There are many methods to correct the long-term trend of the light curve. However, the correction often erases the signal of the stellar rotation from spots crossing the visible stellar disk and other weaker signals like planets. In this work, we present the DiffeRencial flUx Method of cuTting Off biNariES (DRUM TONES) to identify the signal of the binary transits and disentangle it from stellar rotation planet signals. We present our technique with applications to EBs from CoRoT, Kepler, Kepler K2 and TESS missions. We also applied our method to simulated synthetic EB from the PLATO mission. Our method shows good agreement in the determination of stellar rotation periods for few observed targets from last space missions, as well it is naturally useful for future European missions, such as PLAnetary Transits and Oscillations of stars (PLATO).

description: There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their heavy reliance on primary agriculture.

description: This paper analyses the impact of unilateral climate policy on firms’ international location strategies in emission-intensive sectors, when countries differ in terms of market size. The cases of partial and total relocation via foreign direct investment are separately considered. A simple international duopoly model highlights the differences between short-term and long-term effects. In the short-term no change in location is a likely outcome in very capital-intensive sectors, and when there is a strategy shift this takes the form of partial instead of total relocation. In the long-run total relocation becomes a feasible outcome. However we found that, when tighter mitigation measures are introduced by the larger country and unit transport cost is high, with a pronounced market asymmetry the probability of firms not relocating abroad is high even in the long-term. The welfare implications of unilateral environmental measures are assessed considering global industrial pollution and accounting for shifts in location strategy.

description: The microwave response of three high-density bulk MgB2 samples has been investigated in the linear and nonlinear regimes. The three samples, characterized by different mean size of grains, have been obtained by reactive infiltration of liquid Mg in powdered B preforms. The linear response has been studied by measuring the microwave surface impedance; the nonlinear response by detecting the power radiated by the sample at the second-harmonic frequency of the driving field. Our results suggest that bulk MgB2 prepared by the liquid Mg infiltration technique is particularly promising for manufacturing resonant cavities operating at microwave frequencies.

description: The achievement of positive environmental performance at national level could strongly depend on differences in local capabilities of both institutions and the private business sector. Environmental regulation alone is a weak instrument if the institutional and business environment cannot transform regulation strengths into opportunities. In this paper, we use the new environmental accounting matrix for polluting emissions now available for the 20 Italian Regions that covers 24 sectors and combines a shift-share approach with spatial econometric modelling. We provide evidence of the role played by internal innovation, innovation spillovers and regional policies in shaping the geographical distribution of environmental performance achievements.
A Flavor Symmetry for quasi-degenerate Neutrinos: L_mu-L_tau
Creators: name: Choubey, Sandhya

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We consider the flavor symmetry L_mu - L_tau for the neutrino mass matrix. The most general neutrino mass matrix conserving L_mu - L_tau predicts quasi-degenerate neutrino masses with one maximal and two zero mixing angles. The presence of L_mu - L_tau can also be motivated by the near-bimaximal form of the neutrino mixing matrix. Furthermore, it is a special case of mu-tau symmetric mass matrices. Breaking the flavor symmetry by adding a small flavor-blind term to the neutrino mass matrix and/or by applying radiative corrections is shown to reproduce the observed neutrino oscillation phenomenology. Both the normal and inverted mass ordering can be accommodated within this scheme. Moderate cancellation for neutrinoless double beta decay is expected. The observables U_{e3}^2 and |1/2 - \sin^2θ_{23}| are proportional to the inverse of the fourth power of the common neutrino mass scale. We comment on whether the atmospheric neutrino mixing is expected to lie above or below pi/4. We finally present a model based on the see-saw mechanism which generates a light neutrino mass matrix with an (approximate) L_mu - L_tau flavor symmetry. This is a minimal model with just one standard Higgs doublet and three heavy right-handed neutrinos. It needs only small values for the soft L_mu - L_tau breaking terms to reproduce the phenomenological viable mass textures analyzed.

description: To make Robotics and Augmented Reality applications robust to illumination changes, the current trend is to train a Deep Network with training images captured under many different lighting conditions. Unfortunately, creating such a training set is a very unwieldy and complex task. We therefore propose a novel illumination normalization method that can easily be used for different problems with challenging illumination conditions. Our preliminary experiments show that among current normalization methods, the Difference-of Gaussians method remains a very good baseline, and we introduce a novel illumination normalization model that generalizes it. Our key insight is then that the normalization parameters should depend on the input image, and we aim to train a Convolutional Neural Network to predict these parameters from the input image. This, however, cannot be done in a supervised manner, as the optimal parameters are not known a priori. We thus designed a method to train this network jointly with another network that aims to recognize objects under different illuminations: The latter network performs well when the former network predicts good values for the normalization parameters. We show that our method significantly outperforms standard normalization methods and would also be appear to be universal since it does not have to be re-trained for each new application. Our method improves the robustness to light changes of state-of-the-art 3D object detection and face recognition methods.

Conservation and Environmental Education: A Narrative Literature Review

description: Environmental education is an indispensable tool to achieve conservation goals. In order to attain the goals, it becomes necessary to understand various environmental education practices adopted around the world. Hence, an attempt has been made in this paper to review the articles published within the scope of conservation and environmental education. This review paper is not just a presentation of the synopsis, research methods and findings of previous research, but has also endeavoured to test two assumptions: (i) a well-planned and systematically implemented environmental education programme will attain its conservation goals; (ii) the combination of research on conservation and environmental education will be more of quantifiable experiments than mere a superficial awareness raising and sensitisation among the population.

description: In computed tomography, the reconstruction is typically obtained on a voxel grid. In this work, however, we propose a mesh-based reconstruction method. For tomographic problems, 3D meshes have mostly been studied to simulate data acquisition, but not for reconstruction, for which a 3D mesh means the inverse process of estimating shapes from projections. In this paper, we propose a differentiable forward model for 3D meshes that bridge the gap between the forward model for 3D surfaces and optimization. We view the forward projection as a rendering process, and make it differentiable by extending recent work in differentiable rendering. We use the proposed forward model to reconstruct 3D shapes directly from projections. Experimental results for single-object problems show that the proposed method outperforms traditional voxel-based methods on noisy simulated data. We also apply the proposed method on electron tomography images of nanoparticles to demonstrate the applicability of the method on real data.

description: Blockchain-based systems have gained immense popularity as enablers of independent asset transfers and smart contract functionality. They have also, since as early as the first Bitcoin blocks, been used for storing arbitrary contents such as texts and images. On-chain data storage functionality is useful for a variety of legitimate use cases. It does, however, also pose a systematic risk. If abused, for example by posting illegal contents on a public blockchain, data storage functionality can lead to legal consequences for operators and users that need to store and distribute the blockchain, thereby threatening the operational availability of entire blockchain ecosystems. In this paper, we develop and apply a cloud-based approach for quickly discovering and classifying content on public blockchains. Our method can be adapted to different blockchain systems and offers insights into content-related usage patterns and potential cases of abuse. We apply our method on the two most prominent public blockchain systems - Bitcoin and Ethereum - and discuss our results. To the best of our knowledge, the presented study is the first to systematically analyze non-financial content stored on the Ethereum blockchain and the first to present a side-by-side comparison between different blockchains in terms of the quality and quantity of stored data.

Treating consumption : strategies for promoting a sustainable lifestyle
Creators: name: Folz, Harmony Meleta Johanna
Publisher: name: University of British Columbia
Year: 2009

description: Human behaviour, particularly the over-consumption of resources, is highly implicated in the environmental and social ills that face our planet. Therefore, if sustainability is to be achieved, many changes are needed in the way we live our lives. These changes cannot be achieved without significant behaviour change on our part; new technologies, environmental education, and structural changes all will be ineffective unless there is behaviour change. Behaviour change can be incremental and self-reinforcing, so the important thing is not what behaviours need to change, but that some sustainability behaviours are adopted. This thesis examines how these sustainability behaviours could be encouraged. It examines literature on psychological factors influencing behaviour and on behaviour change strategies, using the Precede/Proceed Model as an organizing rubric. From the literature, several conclusions are drawn. First, the goal should be to produce some change, not any specific change. Second, strategies should be comprehensive, and address predisposing, reinforcing, and enabling factors, as well as including provision for evaluation and refinement. This means that information strategies should be used only to give understanding and motivation as part of a comprehensive strategy, that removing barriers and increasing availability/accessibility is necessary, and that skills and feelings of competence and self-efficacy should be developed. Third, change should be voluntary, and chosen by the individual, preferably as part of a participatory problem solving exercise. Fourth, social pressures, roles and commitment should be utilized by program planners, especially through the use of groups; also, people should be told that they are a certain way in order to shift their personal norms, self-concept and social identity towards being someone who acts sustainably. Finally, change should be framed as an improvement to one's lifestyle and people should be made to feel that they can make a difference, and once behaviour has changed, that they are making a difference. Based on these findings, a comprehensive group behaviour change strategy is proposed and outlined.

description: The increased interconnection among local and global players induced by globalization, as well as the need for a complete application of the “subsidiarity principle”, calls for a re-thinking of the “corporate social responsibility” concept. This new concept broadens the perspective of the single company interacting with its own stakeholders in relation to specific social and environmental impacts, to a network of organizations, with different aims and natures, collaborating on relevant sustainability issues. In this paper, the authors will provide a definition of “Territorial Social Responsibility”, sustaining the multi-stakeholder approach as a driver toward local sustainable development. Firstly, theoretical approaches to sustainable development at the territorial level will be examined, identifying the most innovative ideas about governance, network relation and development theories. The idea of development focuses not only on the economic aspects, but on the structural and institutional factors. The existence of cooperative territorial networks is essential to fulfil the creation of tangible and intangible assets at the local level. At the same time, the effectiveness of the decision-making and rules’ system can stimulate and empower territorial networks to tackle sustainable development. An analytical framework, scheme-shaped, will be set in order to identify the main aspects, indicators and practices characterizing the territorial social responsibility concept. It will represent a first attempt to create a feasible instrument aimed at understanding how cooperative social responsible actors, operating in the same territory, could direct the path toward sustainable development.

description: In recent years a growing body of literature has begun to consider the possible presence of path dependence in the development processes of countries. This phenomenon has always been recognized in regional and urban studies because the path of development almost naturally follows a history-dependent spatial diffusion influenced by both physical geography and the quality of institutions. In this paper, I consider the case of firm concentration in Italy and its impact on local development. A large and growing literature has argued in favour of persisting effects of past institutions on current outcomes. Hence, in order to identify the impact of firm density on income, I use instruments from the history of a set of Italian cities: namely the presence of a university and status as a free-city state in the Early Middle Ages. I first show that those two variables had an important effect on the process of urban development between 1300 and 1861, together with favourable geographic conditions. Then, when I use these instruments to predict firm density, I find that the elasticity of income to firm density is close to 0.1. This result is interpreted as providing evidence of the historical roots of agglomeration economies in Italy.

description: The global economic crisis rescued Keynesianism. The current trends of the Brazilian economy, in what has been called "reprimarization", make timely reinvest structuralism in a position of greater prominence in the national economic debate. This is the main objective of this article. For this, we discuss a version of the macroeconomic model of "two-sectors," whereby it sought to show its relevance as a guide to thinking for a number of relevant socioeconomic issues, especially for third world countries. We seek also to demonstrate its consistency with certain empirical evidence and how it can be used as a basis for objective criticism of certain economic strategies that have been proposed for Brazil.

description: 37. Oberthueria lunwan Zolotuhin & Wang, X., 2013 (FIGURES 21 H, 22D)
Oberthueria lunwan Zolotuhin & Wang, X., 2013, Zootaxa 3693 (4): 475. TL: “Yunlong county, Fengshuining Mts., 2460 m, 13 km north of Caojian town, 10–20.V.1999, 25˚46’N, 99˚06’E”.
Diagnosis. The sister species of O. formosibia, which it strongly resembles in general appearance. However, O. lunwan is more yellowish with a less contrasting wing pattern and, uniquely in the genus, almost symmetrical valvae.
Specimens examined. [YUNNAN] Dali Bai Autonomous Prefecture: 1 male, Holotype, Yunlong county, Fengshuining Mts., 2460 m, 13 km north of Caojian town, 10–20.V.1999, 25˚46’N, 99˚06’E, Dr. R. Brechlin leg. (MWM); Paratypes: 1 male, same data as holotype (MWM); Tenchong County: 1 male, Gaoligong Mt, Tenchong, 3000 m, June 1999, Wang & Li leg. (MWM); 1 male, Lijiang/Zhongdian, 27˚29’ N, 99˚53’ E, 24–25.V.2012, 3200 m, Floriani leg. (A. Floriani collection, Milan, Italy).
Bionomics. The larval host is unknown.
Distribution. Mainland China (Yunnan), northeastern Myanmar.
Remarks. This is a high montane species known from altitudes of 1600–3200 m, and only collected in May and June (Zolotuhin & Wang, 2013). However, it probably has a second generation in August. Moths were collected in deep mountain valleys in strongly degraded and therefore sparse secondary forest.

description: We use the spectroscopy and homogeneous photometry of 97 Type Ia supernovae obtained by the \emph{Carnegie Supernova Project} as well as a subset of 36 Type Ia supernovae presented by Zheng et al. (2018) to examine maximum-light correlations in a four-dimensional (4-D) parameter space: $B$-band absolute magnitude, $M_B$, \ion{Si}{2}~$\lambda6355$ velocity, \vsi, and \ion{Si}{2} pseudo-equivalent widths pEW(\ion{Si}{2}~$\lambda6355$) and pEW(\ion{Si}{2}~$\lambda5972$). It is shown using Gaussian mixture models (GMMs) that the original four groups in the Branch diagram are well-defined and robust in this parameterization. We find three continuous groups that describe the behavior of our sample in [$M_B$, \vsi] space. Extending the GMM into the full 4-D space yields a grouping system that only slightly alters group definitions in the [$M_B$, \vsi] projection, showing that most of the clustering information in [$M_B$, \vsi] is already contained in the 2-D GMM groupings. However, the full 4-D space does divide group membership for faster objects between core-normal and broad-line objects in the Branch diagram. A significant correlation between $M_B$ and pEW(\ion{Si}{2}~$\lambda5972$) is found, which implies that Branch group membership can be well-constrained by spectroscopic quantities alone. In general, we find that higher-dimensional GMMs reduce the uncertainty of group membership for objects between the originally defined Branch groups. We also find that the broad-line Branch group becomes nearly distinct with the inclusion of \vsi, indicating that this subclass of SNe Ia may be somehow different from the other groups.

Open and Hidden Charm Production at RHIC and LHC
Creators: name: Vogt, R.

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We discuss aspects of open and hidden charm production in hadron-nucleus collisions at RHIC and LHC energies. We first discuss the extraction of the total charm cross section in lower energy collisions and how it compares to next-to-leading order quantum chromodynamics calculations. We then describe calculations of the transverse momentum distributions and their agreement with the shape of the measured STAR transverse momentum distributions. We next explain how shadowing and moderate nuclear absorption can explain the PHENIX $J/ψ$ dAu/$pp$ ratios.

description: The explosion of disinformation accompanying the COVID-19 pandemic has overloaded fact-checkers and media worldwide, and brought a new major challenge to government responses worldwide. Not only is disinformation creating confusion about medical science amongst citizens, but it is also amplifying distrust in policy makers and governments. To help tackle this, we developed computational methods to categorise COVID-19 disinformation. The COVID-19 disinformation categories could be used for a) focusing fact-checking efforts on the most damaging kinds of COVID-19 disinformation; b) guiding policy makers who are trying to deliver effective public health messages and counter effectively COVID-19 disinformation. This paper presents: 1) a corpus containing what is currently the largest available set of manually annotated COVID-19 disinformation categories; 2) a classification-aware neural topic model (CANTM) designed for COVID-19 disinformation category classification and topic discovery; 3) an extensive analysis of COVID-19 disinformation categories with respect to time, volume, false type, media type and origin source.
