description: In this paper we investigate quantum metastability of a particle trapped in between an infinite wall and a square barrier, with either a time-periodically oscillating barrier (Model A) or bottom of the well (Model B). Based on the Floquet theory, we derive in each case an equation which determines the stability of the metastable system. We study the influence on the stability of two Floquet states when their Floquet energies (real part) encounter a direct or an avoided crossing at resonance. The effect of the amplitude of oscillation on the nature of crossing of Floquet energies is also discussed. It is found that by adiabatically changing the frequency and amplitude of the oscillation field, one can manipulate the stability of states in the well. By means of a discrete transform, the two models are shown to have exactly the same Floquet energy spectrum at the same oscillating amplitude and frequency. The equivalence of the models is also demonstrated by means of the principle of gauge invariance.

The conservation laws in the field theoretical representation of Dirac's theory
Creators: name: Lanczos, Cornelius
Publisher: name: arXiv
Year: 2005
Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: We show that in the new description, Dirac's ``current vector'' is not related to a vector but to a tensor: the ``stress-energy tensor.'' Corresponding to Dirac's conservation law, we have the conservation laws of momentum and energy. The stress-energy tensor consists of two parts: an ``electromagnetic'' part, which has the same structure as the stress-energy tensor of the Maxwell theory, and a ``mechanical'' part, as suggested by hydrodynamics. The connection between these two tensors, which appears organically here, eliminates the well-known contradictions inherent in the dynamics of electron theory. (Editorial note: In this paper Lanczos continues to discuss his ``fundamental equation,'' from which he consistently derives Proca's equation and its stress-energy tensor.)

description: The kinematics of the most metal-poor stars provide a window into the early formation and accretion history of the Milky Way. Here, we use 5~high-resolution cosmological zoom-in simulations ($\sim~5\times10^6$ star particles) of Milky Way-like galaxies taken from the NIHAO-UHD project, to investigate the origin of low-metallicity stars ([Fe/H]$\leq-2.5$). The simulations show a prominent population of low-metallicity stars confined to the disk plane, as recently discovered in the Milky Way. The ubiquity of this finding suggests that the Milky Way is not unique in this respect. Independently of the accretion history, we find that $\gtrsim~90$ per cent of the retrograde stars in this population are brought in during the initial build-up of the galaxies during the first few Gyrs after the Big Bang. Our results therefore highlight the great potential of the retrograde population as a tracer of the early build-up of the Milky Way. The prograde planar population, on the other hand, is accreted during the later assembly phase and samples the full galactic accretion history. In case of a quiet accretion history, this prograde population is mainly brought in during the first half of cosmic evolution ($t\lesssim7$~Gyr), while, in the case of an on-going active accretion history, later mergers on prograde orbits are also able to contribute to this population. Finally, we note that the Milky Way shows a rather large population of eccentric, very metal-poor planar stars. This is a feature not seen in most of our simulations, with the exception of one simulation with an exceptionally active early building phase.

Quantum List Decoding of Classical Block Codes of Polynomially Small Rate from Quantumly Corrupted Codewords

description: Given a classical error-correcting block code, the task of quantum list decoding is to produce from any quantumly corrupted codeword a short list containing all messages whose codewords exhibit high "presence" in the quantumly corrupted codeword. Efficient quantum list decoders have been used to prove a quantum hardcore property of classical codes. However, the code rates of all known families of efficiently quantum list-decodable codes are, unfortunately, too small for other practical applications. To improve those known code rates, we prove that a specific code family of polynomially small code rate over a fixed code alphabet, obtained by concatenating generalized Reed-Solomon codes as outer codes with Hadamard codes as inner codes, has an efficient quantum list-decoding algorithm if its codewords have relatively high codeword presence in a given quantumly corrupted codeword. As an immediate application, we use the quantum list decodability of this code family to solve a certain form of quantum search problems in polynomial time. When the codeword presence becomes smaller, in contrast, we show that the quantum list decodability of generalized Reed-Solomon codes with high confidence is closely related to the efficient solvability of the following two problems: the noisy polynomial interpolation problem and the bounded distance vector problem. Moreover, assuming that NP is not included in BQP, we also prove that no efficient quantum list decoder exists for the generalized Reed-Solomon codes.

description: Il fil rouge di questa miscellanea – che raccoglie solo una piccola parte dei generosi contributi di colleghi, specialisti, studenti che in questi ultimi due anni hanno partecipato con modalità diverse alle attività scientifiche di CRIAR1 – è il legame dell’Uruguay con l’Italia. Un legame, come in più occasioni ci ha ricordato il console generale dottor Ricardo Duarte, che viene dal Risorgimento, dalla presenza di Garibaldi nella Provincia Orientale del Rio della Plata (alla fine del XIX secolo nella sola Montevideo esistevano ben sei vie intitolate all’Eroe dei due mondi e tuttora si contano almeno cinque monumenti a lui dedicati nel paese), e si intensifica a fine ‘800 con l’inizio dell’esodo migratorio europeo nel continente americano.

The nanoscale behaviour of disordered proteins confi ned within biomimetic nuclear pore complexes
Creators: name: Akpinar, Bernice
Publisher: name: Imperial College London
Year: 2019

description: The nuclear pore complex (NPC) forms a nanochannel for selective transport into and out of the cells nucleus. Notably, the transport selectivity of the NPC critically depends on an assembly of intrinsically disordered proteins with multiple phenylalanine-glycine repeats (referred to as FG nups), grafted to the inner walls of the NPC. The focus of this work is to probe the biophysical nature of this indispensable nanochannel by using mimetic systems that emulate key properties of the NPC. Using a DNA origami scaffold, it has been possible to study the configurations adopted by purifi ed FG-nups confi ned to a nanopore geometry that mimics the NPC central channel. In this thesis, atomic force microscopy (AFM) has been used extensively to compare different flavours of FG-nups and to monitor their stochastic behaviour as they form transient condensates that occlude the pore's central lumen. Rearrangements of these entanglements were observed on the timescale of seconds, suggesting that reordering occurs at little energetic cost. This supports the idea that the FG nups are sufficiently 'sticky' or 'cohesive' to form dense condensates that seal the NPC's transport barrier yet are sufficiently dynamic at the molecular scale to facilitate the transport of larger molecules. Furthermore, the dynamics of two different FG-nup (the more cohesive Nup100 and the less cohesive Nsp1) was quantifed using autocorrelation analysis and compared to analogous data acquired on native NPCs. As predicted Nup100 condensates were found to be longer lived than those formed by its less cohesive counterpart Nsp1. By contrast, no fluctuations above the background noise were observed in native NPCs. A possible explanation being due to the presence of soluble transport receptor proteins and molecules caught in transport that trap the FG-nups in given morphologies. To further probe this hypothesis additional components of the transport system have been added to the mimetic nuclear pore complexes and their binding has been visualised with single molecule resolution, both by AFM and by total internal reflection fluorescence microscopy (TIRFM). Importin was seen to bind to both Nup100 and Nsp1 whereby a systematic increase in the number of nucleoporins led to greater binding.

A modified mechanism of the primordial black hole formation is described. A universal log-normal mass spectrum with a mean mass of around $\sim 10 M_\odot$ predicted by this mechanism is strongly confirmed by the LIGO/Virgo observations of gravitational waves from coalescing binary black holes.

description: It was recently discovered that in some regions of the Galaxy, the cosmic ray (CR) abundance is several orders of magnitude higher than previously thought. Additionally, there is evidence that in molecular cloud envelopes, the CR ionization may be dominated by electrons. We show that for regions with high, electron-dominated ionization, the penetration of CR electrons into molecular clouds is modulated by the electric field that develops as a result of the charge they deposit. We evaluate the significance of this novel mechanism of self-modulation and show that the CR penetration can be reduced by a factor of a few to a few hundred in high-ionization environments, such as those found near the Galactic center.

Post-Dayton: prospects for peace in Bosnia-Hercegovina
Creators: name: Tudakovic, Emina Marija
Publisher: name: University of British Columbia
Year: 2009

description: In 1995, after a brutal four-year war in Bosnia and Hercegovina, the initialing of the Dayton Accords brought an end to the violence. By accepting the Accord, the former warring parties agreed on both a cessation of hostilities and a framework for a Bosnian and Hercegovian state. This state has legal existence in international law and consists of two entities, the Federation of Bosnia and Hercegovina and the Republika Srpska. The success of the peace agreement in putting an end to the violence has been witnessed in the past two and a half years. However, the question remains, and this is the principal focus of the thesis, what are the long-term prospects for peace in Bosnia? The analysis focuses on the long-term aspects of ethnic conflict regulation: peace-making and peace-building. The approach used in this analysis is two-fold. First, we rely heavily on Fen Osier Hampson's framework for evaluating the Accords as they fit into the wider body of literature on peace settlements. Second, we employ the assumption that the best way to prevent a recurrence of ethnic conflict is to reverse the processes that led to it in the first place. To that end, we identify some of the processes that led to the war and analyse the present situation in Bosnia as to whether or not these processes are being reversed. The author concludes that although the range of issues covered by Dayton can be generally evaluated as well-written and comprehensive, serious problems remain. Most importantly, the structures put into place do little to reduce the saliency of ethnic ties. Further, although there has been progress, many of the issues which fuelled the conflict remain a problem.

description: This paper is one step toward infinite energy gauge theory and the geometry of infinite dimensional moduli spaces. We generalize a gluing construction in the usual Yang-Mills gauge theory to an ``infinite energy'' situation. We show that we can glue an infinite number of instantons, and that the resulting instantons have infinite energy in general. Moreover we show that they have an infinite dimensional parameter space. Our construction is a generalization of Donaldson's ``alternating method''.

description: We consider the properties of a one dimensional fluid of brownian inertial hard-core particles, whose microscopic dynamics is partially damped by a heat-bath. Direct interactions among the particles are represented as binary, instantaneous elastic collisions. Collisions with the heath bath are accounted for by a Fokker-Planck collision operator, whereas direct collisions among the particles are treated by a well known method of kinetic theory, the Revised Enskog Theory. By means of a time multiple time-scale method we derive the evolution equation for the average density. Remarkably, for large values of the friction parameter and/or of the mass of the particles we obtain the same equation as the one derived within the dynamic density functional theory (DDF). In addition, at moderate values of the friction constant, the present method allows to study the inertial effects not accounted for by DDF method. Finally, a numerical test of these corrections is provided.

description: Operation of semiconductor lasers in the 20--50 $μ$m wavelength range is hindered by strong non-radiative recombination in the interband laser diodes, and strong lattice absorption in GaAs-based quantum cascade structures. Here, we propose an electrically pumped laser diode based on multiple HgTe quantum wells with band structure engineered for Auger recombination suppression. Using a comprehensive model accounting for carrier drift and diffusion, electron and hole capture in quantum wells, Auger recombination, and heating effects, we show the feasibility of lasing at $λ= 26...30$ $μ$m at temperatures up to 90 K. The output power in the pulse can reach up to 8 mW for microsecond-duration pulses.

description: We present a new short proof of the explicit formula for the group of links (and also link maps) in the 'quadruple point free' dimension. Denote by $L^m_{p,q}$ (respectively, $C^{m-p}_p$) the group of smooth embeddings $S^p\sqcup S^q\to S^m$ (respectively, $S^p\to S^m$) up to smooth isotopy. Denote by $LM^m_{p,q}$ the group of link maps $S^p\sqcup S^q\to S^m$ up to link homotopy. Theorem 1. If $p\le q\le m-3$ and $2p+2q\le 3m-6$ then \begin{equation*} L^m_{p,q}\cong π_p(S^{m-q-1})\oplusπ_{p+q+2-m}(SO/SO_{m-p-1})\oplus C^{m-p}_p\oplus C^{m-q}_q. \end{equation*} Theorem 2. If $p, q\le m-3$ and $2p+2q\le 3m-5$ then $LM^m_{p,q}\cong π^S_{p+q+1-m}$. Our approach is based on the use of the suspension operation for links and link maps, and suspension theorems for them.

description: We present precise predictions for the production of a Higgs boson in association with a hadronic jet and a $\mathrm{W}$ boson at hadron colliders. The behaviour of QCD corrections are studied for fiducial cross sections and distributions of the charged gauge boson and jet-related observables. The inclusive process (at least one resolved jet) and the exclusive process (exactly one resolved jet) are contrasted and discussed. The inclusion of QCD corrections up to $\mathcal{O}(α_{\text{s}}^3)$ leads to a clear stabilisation of the predictions and contributes substantially to a reduction of remaining theoretical uncertainties.

Epidemiology of typhoid in India
Creators: name: John, Jacob
Publisher: name: Imperial College London
Year: 2020

description: Hospital based reports suggest a decline in blood culture-confirmed typhoid in India over the past three decades with considerable heterogeneity across risk settings. Extensive use of antibiotics early in febrile illness could decrease the identification of typhoid through blood culture and may therefore be responsible in part for this apparent decline, I measured typhoid incidence through active surveillance of a paediatric cohort in a setting where hospital laboratory reporting declined from 510 cases in 1992 to 98 in 2014 to identify if typhoid transmission persists at the community despite the apparent decline in the hospital. A closed cohort of 6760 children under 15 years of age in Vellore in South India were followed weekly for a median 2.2 years between 11 October 2016 and 15 June 2019 for febrile illness. Participating families received thermometers and fever diary cards and were contacted each day during a febrile illness to record characteristics of fever episodes including antibiotic usage and clinical diagnosis. Fever lasting 3 consecutive days was investigated by study physicians with a blood culture. The incidence of typhoid and of fever related antibiotic use were calculated and the determinants of disease and antibiotic use were examined. We identified 176 blood culture confirmed typhoid cases in 14812 child years of observation, with an incidence of 1187 cases (95% CI, 1025 – 1377) per 100,000 child-years. Correction for sensitivity of blood cultures and refusal of blood culture raised the incidence to 2092 (95% CI, 1869-2330) per 100,000 child-years. Antibiotic use for more than two days decreased the odds of culture confirmation by 46% (95% CI 9% -69%). The incidence of fever-related-antibiotic use was 44 episodes per 100 child years, much usage was inappropriate and early, with azithromycin, amoxycillin and cephalosporins commonly used. Active surveillance of a paediatric cohort demonstrated high incidence of typhoid in the community which is undetected in hospital surveillance. The high incidence warrants use of typhoid conjugate vaccines and highlights the risk posed by emerging MDR to re-emergence of typhoid as a major public health issue.

description: The search for new global scaling relations linking physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially resolved relations has been one of the spotlights of integral field spectroscopy (IFS). In this study we investigate the existence of global and local relations between stellar age ($Age_\star$) and gas-phase metallicity ($Z_g$). To this aim, we analyze IFS data for a sample of 736 star-forming disk galaxies from the MaNGA survey. We report a positive correlation between the global $Z_g$ and $D(4000)$ (an indicator of stellar age), with a slope that decreases with increasing galaxy mass. Locally, a similar trend is found when analyzing the $Z_g$ and $D(4000)$ of the star-forming regions, as well as the residuals resulting from removing the radial gradients of both parameters. The local laws have systematically smaller slopes than the global one. We ascribe this difference to random errors, that make the true slope of the $Age_\star-Z_g$ relation to be systematically underestimated when performing a least square fitting. The explored relation is intimately linked with the already known relation between gas metallicity and star formation rate at fixed mass, both presenting a common physical origin.

description: Mass loss on the Asymptotic Giant Branch provides the origin of planetary nebulae. This paper reviews several relevant aspects of AGB evolution: pulsation properties, mass loss formalisms and time variable mass loss, evidence for asymmetries on the AGB, binarity, ISM interaction, and mass loss at low metallicity. There is growing evidence that mass loss on the AGB is already asymmetric, but with spherically symmetric velocity fields. The origin of the rings may be in pulsational instabilities causing mass-loss variations on time scales of centuries.

description: Many governments impose traditional censorship methods on social media platforms. Instead of removing it completely, many social media companies, including Twitter, only withhold the content from the requesting country. This makes such content still accessible outside of the censored region, allowing for an excellent setting in which to study government censorship on social media. We mine such content using the Internet Archive's Twitter Stream Grab. We release a dataset of 583,437 tweets by 155,715 users that were censored between 2012-2020 July. We also release 4,301 accounts that were censored in their entirety. Additionally, we release a set of 22,083,759 supplemental tweets made up of all tweets by users with at least one censored tweet as well as instances of other users retweeting the censored user. We provide an exploratory analysis of this dataset. Our dataset will not only aid in the study of government censorship but will also aid in studying hate speech detection and the effect of censorship on social media users.

IL TANGO NELLA MILANO DEL PRIMO NOVECENTO: LO STRANO CASO DEL BARONE DE MARCHI

Subjects: tango; Milano

description: Sia pur seconda a Parigi, la Milano dei primi del Novecento accolse con entusiasmo il tango ed ebbe un ruolo di primo piano nella sua diffusione in Italia. Più che una moda, il tango diventò un’ossessione, e la sua musica accompagnava il lancio commerciale di nuovi prodotti, il debutto di marchi e firme, le sfilate di moda. Antonio Oscar De Marchi era nato a Pallanza il 25 di agosto del 1875 e aveva vissuto a Milano fino al 1907, anno in cui si era trasferito a Buenos Aires e aveva sposato la figlia del generale Julio Argentino Roca. Non pare azzardato ipotizzare che proprio Milano, dove il tango veniva apprezzato, praticato e condiviso da persone di diverse estrazioni sociali, possa aver suggerito al Barone De Marchi che anche a Buenos Aires, dove il tango era di casa ma per molti ancora un tabu, si potessero creare le condizioni per il superamento dei pregiudizi.

description: Tra la fine del XIX secolo e l’inizio del XX l’Europa visse un’epoca di relativa pace, industrializzazione, affermazione e sviluppo della scienza e della tecnica e fiducia nel progresso scientifico-tecnologico. Nel contesto della Belle Époque ebbe un considerevole incremento anche la Medicina, ma rimanevano molte questioni aperte, prima tra tutte l’impari lotta contro le malattie infettive. Infatti non era ancora stata messa a punto la sintesi di molecole sintetiche antibatteriche, e diverse malattie, in primisla tubercolosi (principalmente nella sua localizzazione polmonare), rappresentavano una vera e propria “calamità” per la popolazione europea - e non solo europea - dell’epoca. La percezione romantica che si ebbe della tubercolosi nella prima metà dell’Ottocento come malattia elitaria, venne scalzata dal dilagante diffondersi negli strati meno abbienti della società, divenendo il corrispettivo di indigenza e alienazione sociale (la cosiddetta “malattia del proletariato”). La paura antropologica della malattia si stigmatizzò in innumerevoli espressioni artistiche letterarie e visive che rispecchiarono un carattere assai cupo dell’”epoca bella”. Della tubercolosi fu vittima anche Florencio Sánchez (1875-1910), che con le sue disposizioni testamentarie espresse l’intenzione di destinare il suo corpo alla dissezione e alla didattica medica, in una sorta di ultima titanica ribalta nei confronti della malattia.

description: On-shell methods are particularly suited for exploring the scattering of electrically and magnetically charged objects, for which there is no local and Lorentz invariant Lagrangian description. In this paper we show how to construct a Lorentz-invariant S-matrix for the scattering of electrically and magnetically charged particles, without ever having to refer to a Dirac string. A key ingredient is a revision of our fundamental understanding of multi-particle representations of the Poincaré group. Surprisingly, the asymptotic states for electric-magnetic scattering transform with an additional little group phase, associated with pairs of electrically and magnetically charged particles. The corresponding "pairwise helicity" is identified with the quantized "cross product" of charges, $e_1 g_2 - e_2 g_1$, for every charge-monopole pair, and represents the extra angular momentum stored in the asymptotic electromagnetic field. We define a new kind of pairwise spinor-helicity variable, which serves as an additional building block for electric-magnetic scattering amplitudes. We then construct the most general 3-point S-matrix elements, as well as the full partial wave decomposition for the $2\to 2$ fermion-monopole S-matrix. In particular, we derive the famous helicity flip in the lowest partial wave as a simple consequence of a generalized spin-helicity selection rule, as well as the full angular dependence for the higher partial waves. Our construction provides a significant new achievement for the on-shell program, succeeding where the Lagrangian description has so far failed.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: A recursive algebraic method which allows to obtain the Feynman or Schwinger parametric representation of a generic L-loops and (E+1) external lines diagram, in a scalar $ϕ^{3}\oplus ϕ^{4}$ theory, is presented. The representation is obtained starting from an Initial Parameters Matrix (IPM), which relates the scalar products between internal and external momenta, and which appears explicitly when this parametrization is applied to the momentum space representation of the graph. The final product is an algorithm that can be easily programmed, either in a computer programming language (C/C++, Fortran,...) or in a symbolic calculation package (Maple, Mathematica,...).

description: Il lavoro minorile era, ed è ancora in tante parti del mondo, una piaga trasversale, che attraversa continenti e nazioni le più diverse. Per questo nel mio articolo parlo di Sesto San Giovanni, la mia città, e dell’Avana, dove ho vissuto a lungo. Agli inizi del ‘900, il lavoro minorile a Sesto, pesante, malsano, ingiusto, instradava in un percorso professionale che aveva un suo obiettivo perseguibile, diventare un operaio, un tecnico, un impiegato con un lavoro stabile, retribuito regolarmente. Ma all’Avana nemmeno questa prospettiva esisteva. Lo racconta la storia di Kid Chocolate, uno dei migliori pugili di tutti i tempi, che da bambino alternava il lavoro di lustrascarpe con quello di strillone.

description: We generalize the notion of a Rota-Baxter operator on groups and the notion of a Rota-Baxter operator of weight 1 on Lie algebras and define and study the notion of a Rota-Baxter operator on a cocommutative Hopf algebra $H$. If $H=F[G]$ is the group algebra of a group $G$ or $H=U(\mathfrak{g})$ the universal enveloping algebra of a Lie algebra $\mathfrak{g}$, then we prove that Rota-Baxter operators on $H$ are in one to one correspondence with corresponding Rota-Baxter operators on groups or Lie algebras.

description: Quantum systems are often described by parameter-dependent Hamiltonians. Points in parameter space where two levels are degenerate can carry a topological charge. Here we theoretically study an interacting two-spin system where the degeneracy points form a nodal loop or a nodal surface in the magnetic parameter space, similarly to such structures discovered in the band structure of topological semimetals. We determine the topological charge distribution along these degeneracy geometries. We show that these non-point-like degeneracy patterns can be obtained not only by fine-tuning, but they can be stabilized by spatial symmetries. Since simple spin systems such as the one studied here are ubiquitous in condensed-matter setups, we expect that our findings, and the physical consequences of these nontrivial degeneracy geometries, are testable in experiments with quantum dots, molecular magnets, and adatoms on metallic surfaces.

description: Blocks-in-Conduit is a novel approach to cable, coil, and splice technologies with unique benefits for a high-current-den-sity toroid D winding to operate at 20 T, 20 K. Blocks of REBCO tape are cabled in conduit, with a thin-wall center-tube spring that provides transposition, stress management at the cable level, and cross-flow cooling of a thick-coil toroid winding. The coil technology utilizes a co-wound armor structure that integrates stress manage-ment and cross-flow cooling and bypasses coil stress to protect the BIC. An interleaved splice joint enables low-resistance demountable splices of the windings. These provisions yield maximum current density in the winding pack, maximum stability of the REBCO tape blocks, and minimum conductor cost for a tokamak toroid.
High-resolution spectroscopy of SN 2017hcc and its blueshifted line profiles from post-shock dust formation

description: SN2017hcc was remarkable for being a nearby and strongly polarized superluminous TypeIIn supernova (SN). We obtained high-resolution echelle spectra that we combine with other spectra to investigate its line profile evolution. All epochs reveal narrow P~Cygni components from pre-shock circumstellar material (CSM), indicating an axisymmetric outflow from the progenitor of 40-50 km/s. Intermediate-width and broad components exhibit the classic evolution seen in luminous SNe~IIn: symmetric Lorentzian profiles from pre-shock CSM lines broadened by electron scattering at early times, transitioning at late times to multi-component, irregular profiles coming from the SN ejecta and post-shock shell. As in many SNe~IIn, profiles show a progressively increasing blueshift, with a clear flux deficit in red wings of the intermediate and broad velocity components after day 200. This blueshift develops after the continuum luminosity fades, and in the intermediate-width component, persists at late times even after the SN ejecta fade. In SN2017hcc, the blueshift cannot be explained as occultation by the SN photosphere, pre-shock acceleration of CSM, or a lopsided explosion or CSM. Instead, the blueshift arises from dust formation in the post-shock shell and in the SN ejecta. The effect has a wavelength dependence characteristic of dust, exhibiting an extinction law consistent with large grains. Thus, SN2017hcc experienced post-shock dust formation and had a mildly bipolar CSM shell, similar to SN2010jl. Like other superluminous SNeIIn, the progenitor lost around 10Msun due to extreme eruptive mass loss in the decade before exploding.
