description: Em 2024, o Rio Grande do Sul foi atingido por uma enchente histórica, afetando milhares de pessoas que tiveram que deixar suas casas e seus pertences para trás, incluindo documentos e fotografias. Pensando nisso, os participantes do Programa de Educação Tutorial (PET) Conservação e Restauro desenvolveram junto com os professores do curso de Conservação e Restauração de Bens Culturais Móveis da UFPel um projeto voltado a ajudar essas pessoas a resgatarem seus acervos pessoais, o SOS Acervos UFPel. O objetivo do projeto era disseminar informações para que as pessoas atingidas pudessem ter o conhecimento básico de por onde começar esse resgate de objetos danificados. A metodologia utilizada foi a revisão bibliográfica de textos sobre salvaguarda de arquivos após desastres e baseado nisso foram elaborados resumos para o site do PET e roteiros para as publicações de vídeos para o Instagram, sobre os primeiros passos e cuidados na hora de resgatar seus pertences. Foram adaptados em uma linguagem informal visando uma maior compreensão dessas informações pelo público. O material também foi distribuído por meio do WhatsApp. Foram feitas publicações de vídeos com duração média de 1 minuto e carrosséis de fotos, gerando 1.787 interações no Instagram. Os vídeos do SOS Acervos obtiveram 20.033 visualizações enquanto o restante que foram postados no último ano alcançaram 30.622 visualizações, uma diferença de 65% que mostra um resultado positivo no alcance de público e divulgação dos vídeos.
title: Identifying Nascent High-Growth Firms Using Machine Learning

description: Predicting which firms will grow quickly and why has been the subject of research studies for many decades. Firms that grow rapidly have the potential to usher in new innovations, products or processes (Kogan et al. 2017), become superstar firms (Haltiwanger et al. 2013) and impact the aggregate labour share (Autor et al. 2020; De Loecker et al. 2020). We explore the use of supervised machine learning techniques to identify a population of nascent high-growth firms using Canadian administrative firm-level data. We apply a suite of supervised machine learning algorithms (elastic net model, random forest and neural net) to determine whether a large set of variables on Canadian firm tax filing financial and employment data, state variables (e.g., industry, geography) and indicators of firm complexity (e.g., multiple industrial activities, foreign ownership) can predict which firms will be high-growth firms over the next three years. The results suggest that the machine learning classifiers can select a sub-population of nascent high-growth firms that includes the majority of actual high-growth firms plus a group of firms that shared similar attributes but failed to attain high-growth status.
description: Les chercheurs étudient depuis des décennies la question de savoir comment prédire quelles entreprises vont connaître une croissance rapide et pour quelles raisons. Les entreprises qui croissent rapidement sont susceptibles d’introduire des innovations, de lancer de nouveaux produits ou de mettre en place des processus inédits (Kogan et autres, 2017), de devenir des entreprises phares (Haltiwanger et autres, 2013) et d’avoir une incidence sur la part globale du travail (Autor et autres, 2020; De Loecker et autres, 2020). Nous explorons l’utilisation de techniques d’apprentissage automatique supervisé pour cerner un groupe d’entreprises émergentes à forte croissance en nous basant sur des données administratives sur les entreprises canadiennes. Nous appliquons un ensemble d’algorithmes d’apprentissage automatique supervisé (modèle du filet élastique, forêt aléatoire et réseau neuronal) pour déterminer si un vaste éventail de variables concernant des entreprises canadiennes – données sur la situation financière et l’emploi tirées des déclarations fiscales, données descriptives (p. ex., secteur, emplacement géographique) et indicateurs de complexité (p. ex., activités industrielles multiples, détention par des étrangers) – peuvent prédire celles qui afficheront une forte croissance au cours des trois années à venir. Les résultats obtenus donnent à penser que les classifieurs d’apprentissage automatique peuvent sélectionner un sous-groupe d’entreprises émergentes composé d’une majorité d’entreprises qui enregistrent réellement une croissance élevée et d’autres qui, même en ayant des attributs similaires, n’ont pas réussi à atteindre un fort niveau de croissance.

description: At visible and infrared frequencies, metals show tantalizing promise for strong subwavelength resonances, but material loss typically dampens the response. We derive fundamental limits to the optical response of absorptive systems, bounding the largest enhancements possible given intrinsic material losses. Through basic conservation-of-energy principles, we derive geometry-independent limits to per-volume absorption and scattering rates, and to local-density-of-states enhancements that represent the power radiated or expended by a dipole near a material body. We provide examples of structures that approach our absorption and scattering limits at any frequency, by contrast, we find that common "antenna" structures fall far short of our radiative LDOS bounds, suggesting the possibility for significant further improvement. Underlying the limits is a simple metric, $|χ|^2 / \operatorname{Im} χ$ for a material with susceptibility $χ$, that enables broad technological evaluation of lossy materials across optical frequencies.

title:  Una libertà non situata: la scelta originale nell’Essere e il Nulla e il Baudelaire
Creators: name: de Coorebyter  ,  Vincent
Publisher: name: Roma TrE-Press
Year: 2018

description: L’articolo indaga l’ambizione di Sartre di rendere intelligibile la singolarità individuale, cioè di cogliere il progetto originale che caratterizza ogni esistenza e che deve poi confrontarsi con la realtà delle condizioni personali, sociali e storiche. Si tratta di una delle principali costanti della ricerca filosofica sartriana. A partire dai Taccuini della strana guerra, “romanzo filosofico” di un uomo che scopre il suo inserimento nella Storia, l’autore continua ad analizzare e a ripensare il rapporto tra libertà e situazione: è la libertà che dà senso alla situazione o è la situazione che pesa sulla libertà individuale tanto da condizionarla irrimediabilmente?  Sartre sembra restare fedele al programma ermeneutico tracciato nell’Essere e il nulla. Dal Kaiser Guglielmo II a Baudelaire, da Genet a Flaubert le biografie sartriane rappresentano un progressivo e sempre più efficace tentativo di scoprire lo spessore dell’essere-per-altri, un complesso sistema di relazioni e condizionamenti reciproci in cui le finalità individuali si intersecano e si trasformano.

Temperature-based metallicity measurements at z=0.8: direct calibration of strong-line diagnostics at intermediate redshift

description: We present the first direct calibration of strong-line metallicity diagnostics at significant cosmological distances using a sample at z=0.8 drawn from the DEEP2 Galaxy Redshift Survey. Oxygen and neon abundances are derived from measurements of electron temperature and density. We directly compare various commonly used relations between gas-phase metallicity and strong line ratios of O, Ne, and H at z=0.8 and z=0. There is no evolution with redshift at high precision ($Δ\log{\mathrm{O/H}} = -0.01\pm0.03$, $Δ\log{\mathrm{Ne/O}} = 0.01 \pm 0.01$). O, Ne, and H line ratios follow the same locus at z=0.8 as at z=0 with $\lesssim$0.02 dex evolution and low scatter ($\lesssim$0.04 dex). This suggests little or no evolution in physical conditions of HII regions at fixed oxygen abundance, in contrast to models which invoke more extreme properties at high redshifts. We speculate that offsets observed in the [N II]/H$α$ versus [O III]/H$β$ diagram at high redshift are therefore due to [NII] emission, likely as a result of relatively high N/O abundance. If this is indeed the case, then nitrogen-based metallicity diagnostics suffer from systematic errors at high redshift. Our findings indicate that locally calibrated abundance diagnostics based on alpha-capture elements can be reliably applied at z$\simeq$1 and possibly at much higher redshifts. This constitutes the first firm basis for the widespread use of empirical calibrations in high redshift metallicity studies.

title: Managerial Compensation, Investment and Financial Leverage: An Empirical Analysis of UK Firms.
Creators: name: Adu-Ameyaw, E
Publisher: name: Liverpool John Moores University
Year: 2020

description: This thesis examines the causal effects of the different components of managerial compensation on the value-critical risk-taking activities, particularly those linked to investment, and financial leverage. Employing a three-stage least squares (3SLS) technique in a system of equations, the study makes interesting contributions to the growing strand of literature using datasets from the UK (FTSE 350) companies for the period 2006 – 2015. Specifically, this scholarly study contributes to the extant literature in three ways. First, the study finds that higher long-term incentive plans (LTIPs) and stock options incentive cause more investment in capital expenditure and fixed intangible but less in research and development activity, whilst greater cash bonus induces more intangibles (research and development and fixed intangible) investment but less capital expenditure activity. Largely, the presented evidence is contrary to the view that the risk-motivated incentives (stock options and LTIPs) encourage more riskier activity like R&D. Rather, shareholders use risk-avoiding incentive (cash bonus) to reduce managerial risk-related agency problems. Further, the result suggests that higher LTIPs and stock options lead to lower spending on other fixed asset activities, which is inconsistent with the risk-related argument. Second, the study further contributes to the optimal contracting theory by suggesting that the level and the effectiveness of managerial compensation induces capital expenditure investment distortions. Specifically, the research finds that extremely over-compensated (under- compensated) managers are more (less) likely to commit over-investment in capital expenditure. In contrast, extremely over-compensated (under-compensated) managers have a decreased (increased) probability of over-investing in research and development. Finally, the finding shows that LTIPs (stock options) has a positive (negative) impact on leverage, which is consistent (inconsistent) with the alignment (risk-motivated incentive) hypothesis, whilst the cash bonus finding shows support for the risk-reduction assumption. The study also observes that shareholders use more debt-like incentive (deferred stock) to reduce the risk-shifting incentive problem and lower agency cost of debt. The evidence further reveals that the effectiveness of the stock options (risk-motivated) incentive to induce managerial risk- taking decisions via borrowings is limited to high-growth opportunity firms. Additionally, consistent with the alignment hypothesis, the study finds that highly monitored (governed) firms use the LTIPs incentive to influence managers to contract more debt; however, the stock options incentive discourages more borrowing in such governing state. This tends to support the view that the firm’s remuneration committee applies LTIPs in lieu of stock options to minimise managerial excessive risk-taking.

description: Die 360°-Trainingswelt „VR-FipS – Führung in praxisorientierten Situationen“ ermöglicht eine praxisnahe und realistische Vorbereitung auf das Führen von Soldaten im Kontext militärischer Ausbildung. Das Durchlaufen der einzelnen Trainingsphasen in der virtuellen Lernumgebung – von der Geländeorientierung, über die Befehlsausgabe, bis hin zur Verletztenversorgung – gibt den Soldaten in der Ausbildung die Gelegenheit, authentische militärische Einsatzsituationen nachzuerleben und ihre Reaktionen auf führungstypische Impulse zu reflektieren. Offizieranwärter lernen dadurch generische Handlungsmuster des militärischen Führens und können somit gelassener und flexibler in verschiedenen Ausbildungsabschnitten der Offizierprüfung agieren. Die Simulation wurde als 360°-Film basierte Trainingswelt umgesetzt und kann sowohl über ein Head-Mounted Display als auch auf dem Handy oder Desktop rezipiert werden. Interessenten können durch eine Anfrage bei den Autoren einen Link zur Lernumgebung empfangen.

Es fehlt bislang die Möglichkeit, die Teilnehmer auf ein realistisches Szenario vorzubereiten, in dem Erste Hilfe geleistet werden muss. Der Stress, der Zeitdruck und die Umwelteinflüsse wirken auf die Handlungen des Ersthelfers. Um eine solche Situation trainieren zu können, wurde gemeinsam mit gemeinnützigen und privaten Hilfsorganisationen die VR-Simulation „Erste Hilfe Szenario“ konzeptioniert und in Teilen auch bereits entwickelt. Dabei wird der Anwender Zeuge eines Verkehrsunfalls und muss die zuvor im Präsenztraining vermittelten Wissensinhalte in einer simulierten Stresssituation bewältigen. Nach Fertigstellung soll die App in Erste Hilfe Schulungen integriert und evaluiert werden.
title:  Necessità e libertà in Sartre – Tra il progetto incompiuto di un’etica esistenzialista e il materialismo di Critica della ragione dialettica
Creators: name: Russo  ,  Maria
Publisher: name: Roma TrE-Press
Year: 2018

description: In questo contributo s’intende indagare il cambiamento nella concezione di libertà di Jean-Paul Sartre da L’essere e il nulla a Critica della ragione dialettica, transitando per il tentativo di formulare un’etica esistenzialista nei Quaderni per una morale. All’interno dell’opera di Sartre, si passa da una libertà radicale e assoluta a una condizionata dal contesto storico e dal residuo ineliminabile del pratico-inerte. Dalla possibilità sempre aperta della libertà si approda all’ingresso della Necessità nella storia e nelle dinamiche di contro-violenza che si sviluppano a partire dalla lotta di classe, in una visione più conciliatoria con il marxismo e con la psicanalisi. Nonostante questa incarnazione della libertà impegnata degli anni Sessanta, al termine della sua vita, nell’ultima controversa intervista, Sartre rimpiangerà il suo tentativo mancato di elaborare una morale esistenzialista e, ancora una volta, rimetterà in discussione le sue categorie per recuperare un aspetto normativo del suo esistenzialismo.

description: The ability to synthesize high-quality samples over large areas and at low cost is one of the biggest challenges during the developmental stage of any novel material. While chemical vapor deposition (CVD) methods provide a promising low-cost route for CMOS compatible, large-scale growth of materials, it often falls short of the high-quality demands in nanoelectronics and optoelectronics. We present large-scale CVD synthesis of single- and few- layered MoS2 using direct vapor-phase sulfurization of MoO2, which enables us to obtain extremely high-quality single-crystal monolayer MoS2 samples with field-effect mobility exceeding 30 cm2/Vs in monolayers. These samples can be readily synthesized on a variety of substrates, and demonstrate a high-degree of optoelectronic uniformity in Raman and photoluminescence mapping over entire crystals with areas exceeding hundreds of square micrometers. Owing to their high crystalline quality, Raman spectroscopy on these samples reveal a range of multi-phonon processes through peaks with equal or better clarity compared to past reports on mechanically exfoliated samples. This enables us to investigate the layer thickness- and substrate-dependence of the extremely weak phonon processes at 285 cm-1 and 487 cm-1 in 2D MoS2. The ultra-high, optoelectronic-grade crystalline quality of these samples could be further established through photocurrent spectroscopy, which clearly reveal excitonic states at room temperature, a feat that has been previously demonstrated only on device fabricated with mechanically exfoliated that were artificially suspended across trenches. Our method reflects a big step in the development of atomically thin, 2D MoS2 for scalable, high-quality optoelectronics.

description: The acknowledgement of the territory vocation is founded on the research of its peculiarities which determine the uniqueness of that production area. In this paper, results concerning the first contributions to characterize terroir environment components of Taggiasca olive in Imperia province are presented and discussed. GIS was used to improve the process of landscape characterization. Several profiles from distinct production olive groves were selected for full pedological description and analysis. The analysis showed that the olive groves were mainly located in areas characterized by the following aspects: average annual rainfall between 800 and 1200 mm/y, average annual temperature between 11° and 17° C, altitude between 0 and 400 m a.s.l., acclivity between 5° and 15° and exposure on west slope. Moreover, the research highlighted a number of distinctive features of soils which were characterized by properties rather homogeneous, e.g. moderate depth, good drainage, sub-alkaline reaction, good organic carbon, phosphorus and total nitrogen contents. Finally, we suggested an update of the official PDO EVO production protocols regarding the environment of Taggiasca olive.

description: В последнее время уделяется большое внимание проблеме послеродовой депрессии связи с тем, что она имеет прямое влияние не только на здоровье и безопасность матери, но и на состояние новорожденного, его когнитивное развитие и социальное взаимодействие [1-9]. В ряде случаев послеродовая депрессия у матери может стать причиной развития хронической депрессии с последующим влиянием на ее дальнейшую жизнь и формирование отношений мать – ребенок [7, 10-12]. Женщины с депрессивной симптоматикой не способны в полной мере ухаживать за новорожденным и полноценно взаимодействовать с членами своей семьи [6-8, 10, 13, 14]. Поскольку этиология развития депрессии в послеродовом периоде является мультифакторной, исследования таких авторов, как Melzack R. Et al. (1999), Eisenach J.C. et al. (2008), Seth S. et al. (2016), Kountanis J. еt al. (2019), Freedman S.A. (2020), показали, что одной из причин ее развития являются выраженная боль и перенесенный стресс [7, 15-17]. Кроме этого, значительное влияние на частоту развития ПРД имеет исходное психоэмоциональное состояние пациенток [18]. В связи с этим мы предположили, что эффективное обезболивание в виде применения эпидуральной анальгезии при родоразрешении через естественные родовые пути у женщин с исходным нарушением психоэмоционального статуса может снизить вероятность возникновения послеродовой депрессии.

description: In NW Italy, the abandonment of traditional farming is causing the loss of small artificial water reservoirs that are often used by amphibians as trophic and breeding habitats. Starting in 2010, a regional conservation project implemented in Val di Vara (Liguria, NW Italy), had the goal of improving the conservation status of the endangered Yellow-bellied toad (Bombina pachypus) and other local amphibians. During this project, nine artificial tanks equipped with special concrete ramps were built. These artificial tanks were constructed under the responsibility of Montemarcello-Magra-Vara Regional Park managers, while local landowners committed to their maintenance by signing an agreement. After more than 10 years, all the tanks are still functional and have been used by five amphibian species (Bombina pachypus, Ichthyosaura alpestris, Rana dalmatina, Salamandra salamandra and Triturus carnifex), as reproductive or shelter habitats. Moreover, five of the tanks are still used for watering livestock or as nature-based attractors and thus were beneficial to local farmers. These long-term positive outcomes of the project highlight that traditional farming systems may effectively protect both Mediterranean cultural landscape and local biodiversity.

title:  La libertà del militante. Sartre e la rivoluzione tra progetto, libertà e situazione
Creators: name: Castelli, Federica
Publisher: name: Roma TrE-Press
Year: 2018

description: L'articolo indaga le varie fasi del pensiero sartriano e del suo impegno politico, interrogando il filosofo circa il nodo del rapporto tra soggettività e processo rivoluzionario, tra ideologia, determinismo, burocratizzazione e derive violente e totalitarie. È possibile una teoria dell'agire rivoluzionario che salvi i soggetti dalla cancellazione all'interno di teorie a priori, dogmi politici, futuri lontani in nome dei quali sacrificare il presente? È possibile immaginare una rivoluzione che tenga al centro i soggetti in relazione tra loro, senza prescindere dalla loro libertà e progettualità? È possibile riformulare la teoria marxiana, rideclinandola in un'ottica esistenzialista? Il testo prova a rispondere a tali interrogativi, interloquendo con i testi, le opere, l'impegno e il vissuto di Jean-Paul Sartre.

description: We study the importance of interband effects on the orbital susceptibility of three bands $α$-${\cal T}_3$ tight-binding models. The particularity of these models is that the coupling between the three energy bands (which is encoded in the wavefunctions properties) can be tuned (by a parameter $α$) without any modification of the energy spectrum. Using the gauge-invariant perturbative formalism that we have recently developped, we obtain a generic formula of the orbital susceptibility of $α$-${\cal T}_3$ tight-binding models. Considering then three characteristic examples that exhibit either Dirac, semi-Dirac or quadratic band touching, we show that by varying the parameter $α$ and thus the wavefunctions interband couplings, it is possible to drive a transition from a diamagnetic to a paramagnetic peak of the orbital susceptibility at the band touching. In the presence of a gap separating the dispersive bands, we show that the susceptibility inside the gap exhibits a similar dia to paramagnetic transition.

description: The "green valley" is a wide region separating the blue and the red peaks in the ultraviolet-optical color magnitude diagram, first revealed using GALEX UV photometry. The term was coined by Christopher Martin in 2005. Green valley highlights the discriminating power of UV to very low relative levels of ongoing star formation, to which the optical colors, including u-r, are insensitive. It corresponds to massive galaxies below the star-forming "main" sequence, and therefore represents a critical tool for the study of the quenching of star formation and its possible resurgence in otherwise quiescent galaxies. This article reviews the results pertaining to morphology, structure, environment, dust content and gas properties of green valley galaxies in the local universe. Their relationship to AGN is also discussed. Attention is given to biases emerging from defining the "green valley" using optical colors. We review various evolutionary scenarios and we present evidence for a new, quasi-static view of the green valley, in which the majority of galaxies currently in the green valley were only partially quenched in the distant past and now participate in a slow cosmic decline of star formation, which also drives down the activity on the main sequence, presumably as a result of the dwindling accretion/cooling onto galaxy disks.

description: L’articolo parte da un esame delle tesi sostenute da Sartre, nell’ultima parte de L’intelligibilité de l’Histoire (Critique de la Raison dialectique, tomo II), riguardo al rapporto tra la vita organica, la prassi e l’inorganico. Su questi temi vengono poi individuati alcuni punti che nell’incompiuto testo sartriano restano aporetici. Si propone infine una possibile via d’uscita dalle aporie, mediante una particolare interpretazione della kinesis vivente, del lavoro come prassi segnico-strumentale e del divenire umano come progetto transistorico.

description: We present multi-epoch non-redundant masking observations of the T Cha transition disk, taken at the VLT and Magellan in H, Ks, and L' bands. T Cha is one of a small number of transition disks that host companion candidates discovered by high-resolution imaging techniques, with a putative companion at a position angle of 78 degrees, separation of 62 mas, and contrast at L' of 5.1 mag. We find comparable binary parameters in our re-reduction of the initial detection images, and similar parameters in the 2011 L', 2013 NaCo L', and 2013 NaCo Ks data sets. We find a close-in companion signal in the 2012 NaCo L' dataset that cannot be explained by orbital motion, and a non-detection in the 2013 MagAO/Clio2 L' data. However, Monte-carlo simulations show that the best fits to the 2012 NaCo and 2013 MagAO/Clio2 followup data may be consistent with noise. There is also a significant probability of false non-detections in both of these data sets. We discuss physical scenarios that could cause the best fits, and argue that previous companion and scattering explanations are inconsistent with the results of the much larger dataset presented here.

description: Рынок органической продукции и спрос на качественные продукты в мире растет стремительно. В настоящее время нормативно-правовая система регулирования рынка органической продукции России представляет собой комплекс законов, стандартов, требований не только российских, но и международных. Она включает как специальные правовые акты, так и общехозяйственные, а также как федеральные, так и региональные. Формирование правового поля в этой области происходит в сложных условиях: в период экономического кризиса, санкций и антисанкций. Авторами указывается, что разработка форм и методов государственного регулирования рынка органической продукции создаст условия для эволюции органического земледелия и фермерства в России. Это, в свою очередь, позволит обеспечить экологически чистой продукцией не только граждан страны, но и предоставит возможность отечественным организациям стать полноправными игроками на международном органическом рынке.

description: Based on an extension of the holographic principle to superspace, we provide a strong-coupling description of smooth super Wilson loops in terms of minimal surfaces of the $AdS_5 \times S^5$ superstring. We employ the classical integrability of the Green-Schwarz superstring on $AdS_5 \times S^5$ to derive the superconformal and Yangian $Y[\mathfrak{psu}(2,2|4)]$ Ward identities for the super Wilson loop, thus extending the strong coupling results obtained for the Maldacena-Wilson loop. In the course of the derivation, we determine the minimal surface solution up to third order in an expansion close to the conformal boundary.

description: Необходимость районирования территории Азербайджанской республики диктуется наличием разнообразия природных условий, которые влияют на хозяйственную деятельность человека. Назначение любого районирования заключается в возможности решения определённых научных и практических задач. В настоящее время в пересмотре существующего районирования территории Азербайджана, возникла необходимость в связи с переходом от директивных методов управления сельскохозяйственным производством к экономичным методам управления, основанных на рыночных отношениях. Помимо этого результаты районированной территории могут быть применены при проведении консолидации сельскохозяйственных земель в стране.

description: We present results from a fifteen-month campaign of high-cadence (~ 3 days) mid-infrared Spitzer and optical (B and V ) monitoring of the Seyfert 1 galaxy NGC 6418, with the objective of determining the characteristic size of the dusty torus in this active galactic nucleus (AGN). We find that the 3.6 $μ$m and 4.5 $μ$m flux variations lag behind those of the optical continuum by $37.2^{+2.4}_{-2.2}$ days and $47.1^{+3.1}_{-3.1}$ days, respectively. We report a cross-correlation time lag between the 4.5 $μ$m and 3.6 $μ$m flux of $13.9^{+0.5}_{-0.1}$ days. The lags indicate that the dust emitting at 3.6 $μ$m and 4.5 $μ$m is located at a distance of approximately 1 light-month (~ 0.03 pc) from the source of the AGN UV-optical continuum. The reverberation radii are consistent with the inferred lower limit to the sublimation radius for pure graphite grains at 1800 K, but smaller by a factor of ~ 2 than the corresponding lower limit for silicate grains; this is similar to what has been found for near-infrared (K-band) lags in other AGN. The 3.6 and 4.5 $μ$m reverberation radii fall above the K-band $τ\propto L^{0.5}$ size-luminosity relationship by factors $\lesssim 2.7$ and $\lesssim 3.4$, respectively, while the 4.5 $μ$m reverberation radius is only 27% larger than the 3.6 $μ$m radius. This is broadly consistent with clumpy torus models, in which individual optically thick clouds emit strongly over a broad wavelength range.
