description: We have analyzed nearly all images of the Taurus star-forming region at 3.6-24um that were obtained during the cryogenic mission of the Spitzer Space Telescope (46 deg^2) and have measured photometry for all known members of the region that are within these data, corresponding to 348 sources. We have classified the members of Taurus according to whether they show evidence of disks and envelopes (classes I, II, and III). The disk fraction in Taurus is 75% for solar-mass stars and declines to 45% for low-mass stars and brown dwarfs (0.01-0.3 M_sun). This dependence on stellar mass is similar to that measured for Cha I, although the disk fraction in Taurus is slightly higher overall, probably because of its younger age (1 vs. 2-3 Myr). In comparison, the disk fraction for solar-mass stars is much lower (20%) in IC 348 and Sigma Ori, which are denser than Taurus and Cha I and are roughly coeval with the latter. These data indicate that disk lifetimes for solar-mass stars are longer in regions that have lower stellar densities. Through an analysis of multiple epochs of photometry that are available for ~200 Taurus members, we find that stars with disks exhibit significantly greater mid-IR variability than diskless stars. Finally, we have used our data in Taurus to refine the criteria for primordial, evolved, and transitional disks. The number ratio of evolved and transitional disks to primordial disks in Taurus is 15/98 for K5-M5, indicating a timescale of 0.15 x tau(primordial)=0.45 Myr for the clearing of the inner regions of optically thick disks. After applying the same criteria to older clusters (2-10 Myr), we find that the proportions of evolved and transitional disks in those populations are consistent with the measurements in Taurus when their star formation histories are properly taken into account. ERRATUM: In Table 7, we inadvertently omitted the spectral type bins in which class II sources were placed in Table 8 based on their bolometric luminosities (applies only to stars that lack spectroscopic classifications). The bins were K6-M3.5 for FT Tau, DK Tau B, and IRAS 04370+2559, M3.5-M6 for IRAS 04200+2759, IT Tau B, and ITG 1, and M6-M8 for IRAS 04325+2402 C. In addition, the values of K_s-[3.6] in Table 13 and Figure 26 for spectral types of M4-M9 are incorrect. We present corrected versions of Table 13 and Figure 26.

'Talking Things': Bridging Social Capital through Transformation Design
Creators: name: Contractor, Zara
Publisher: name: Emily Carr University of Art and Design
Year: 2013
Subjects: Community--Urban Planning--Social capital--Sociology--Transformation

description: The importance of building social capital, particularly in urban neighbourhoods has been a topic of discussion for sociologists, political scientists and psychologists for some time now. This thesis addresses the issue through the lens of an emergent branch of design known as Transformation Design, which focuses on collaborative and multidisciplinary ways of creating a change in behavior through design. Employing participatory methods and borrowing from theories of narrative empathy and Thing theory, this thesis describes a praxis centred around the design of an experience where the exchange of narratives around everyday objects of personal significance creates a dialogic learning experience that builds social capital. The resulting project, Talking Things, is a toolkit that is intended to encourage dialogues amongst members at community centres and neighbourhood houses, but can be adapted and employed in other circumstances where the goal is to build a sense of belonging and community. The toolkit describes a workshop with step-by-step instructions to prompt and facilitate the exchange of narratives. Though the primary objective is to engage people in an informal, collaborative learning experience, the stories can be recorded and have an online presence that sustains the conversations. This thesis contributes to the growing discourse of the designer’s role within a community, which stretches beyond the designing of places and things; and into an agent of change.
Between Private and Public: The Artist in Flux

Subjects: Participatory art--Video Art--Process--Ritual--Collaboration

description: This thesis essay explores my growth as an artist over the course of the MAA, Visual Arts Stream. Initially, I investigate a conventional private studio practice that explores ritual (Bataille), subjectivity (Baudrillard), defamiliarization (Viktor Schlovsky) and the act of looking (Mark Lewis). Later, it documents a shifting towards a practice that is collaborative, participatory, or otherwise open to others and that borrows techniques and tropes from community art (Betsy Damon, Suzanne Lacy), social practice (Anthony Schrag, Claire Bishop) and dialogical practice (Grant Kester, Stephen Willats). The thesis art work explored in the essay includes various video projects from the first year of the MAA which demonstrate my explorations of ritual and subjectivity (Waver Dither Falter, Water Oil Wine, Benny). I also explore an ongoing series of projects from the second year of my MAA, which incorporate participation and collaboration with others as a means of experimenting with the possibilities of an open practice (The We Sessions). Though all the works result in immersive video installations around the subject of ritual, the process changes in the latter work. Specifically, The We Sessions, combined with the research essay, question the implications of these changes from historical, artistic, and critical viewpoints, both for myself and also for the art-world at large.

Complexity

description: A key ingredient of computational argumentation in AI is the generation of arguments in favor or against claims under scrutiny. In this paper we look at the complexity of the argument generation procedure in the prominent structured formalism of assumption-based argumentation (ABA). We show several results connecting expressivity of ABA fragments and number of constructed arguments. First, for several NP-hard fragments of ABA, the number of generated arguments is not bounded polynomially. Even under equivalent rewritings of the given ABA framework there are situations where one cannot avoid an exponential blow-up. We establish a weaker notion of equivalence under which this blow-up can be avoided. As a general tool for analyzing ABA frameworks and resulting arguments and their conflicts, we extend results regarding dependency graphs of ABA frameworks, from which one can infer structural properties on the induced attacks among arguments.

description: In this paper we discuss progress made in the study of the Jones polynomial from the point of view of quantum mechanics. This study reduces to the understanding of the quantization of the moduli space of flat SU(2)-connections on a surface with the Chern-Simons lagrangian. We outline some background material, then present the particular example of the torus, in which case it is known that the quantization in question is the Weyl quantization. The paper concludes with a possible application of this theory to the study of the fractional quantum Hall effect, an idea originating in the works of Moore and Read.

description: At low temperature, a quasi-one-dimensional ensemble of atoms with attractive interaction forms a bright soliton. When exposed to a weak and smooth external potential, the shape of the soliton is hardly modified, but its center-of-mass motion is affected. We show that in a spatially correlated disordered potential, the quantum motion of a bright soliton displays Anderson localization. The localization length can be much larger than the soliton size and could be observed experimentally.

description: Modern tourism in the 21st century is facing numerous challenges. One of these challenges is the rapidly growing number of tourists in space limited regions such as historical city centers, museums or geographical bottlenecks like narrow valleys. In this context, a proper and accurate prediction of tourism volume and tourism flow within a certain area is important and critical for visitor management tasks such as visitor flow control and prevention of overcrowding. Static flow control methods like limiting access to hotspots or using conventional low level controllers could not solve the problem yet. In this paper, we empirically evaluate the performance of several state-of-the-art deep-learning methods in the field of visitor flow prediction with limited data by using available granular data supplied by a tourism region and comparing the results to ARIMA, a classical statistical method. Our results show that deep-learning models yield better predictions compared to the ARIMA method, while both featuring faster inference times and being able to incorporate additional input features.
Absurd Naturalism: Field Biology on the Crust of the Earth

Subjects: Biology--DIY--Craft--Genetics--Collections--Installations--Sculpture

description: This project examines the growth and accumulation of collections, and the political implications of categorization in three installations: Lithosphere, Stones Shaped by Chance, and Chelonioidea. These installations invent worlds in a parallel universe; with their own biologies and genetics. They are influenced by scientific initiatives such as The Human Genome Project and Biosphere 2, which provide a conceptual framework for artworks that examine systems for life cycles and analysis. Using taxonomy, horror vacui, encyclopedias, and cabinets of curiosities as references, I accumulate my own collections with an awareness of the idiosyncrasies inherent to any collection. I use the term Absurd Naturalism to describe the impossibility of maintaining a neutral and omniscient standpoint as the creator of a collection. In this way, it also describes the field I am working in – problems and solutions circle one another until they are indistinguishable, and the work comes out of the center of this spiral. My installations take form by interpreting ecological systems, using handmade, crafted, and found materials. Repetition, mutation, and reproduction are central in both the content and the methodology. Drawing is the source of all mutations. Here, the aesthetics of DIY, childhood craft, queer spaces, and underground punk are used to question the authority of information and the meaning of scientific facts. While artists such as Albertus Seba and Luigi Serafini provide a conceptual basis for my work, collectives such as Paper Rad and Wham City serve as both my contemporaries, and my audience. Growth and categorization oscillate between the personal and the political in this project. The research questions move under my own skin and back into the studio. I am interested in genetics as the basis for familial relation and sameness, genetic mutation as a marker for change, and how genetics functions in redefining the category of biological life.

description: We study the phase diagram of the frustrated $t{-}t^\prime$ Hubbard model on the square lattice by using a novel variational wave function. Taking the clue from the backflow correlations that have been introduced long-time ago by Feynman and Cohen and have been used for describing various interacting systems on the continuum (like liquid $^3$He, the electron jellium, and metallic Hydrogen), we consider many-body correlations to construct a suitable approximation for the ground state of this correlated model on the lattice. In this way, a very accurate {\it ansatz} can be achieved both at weak and strong coupling. We present the evidence that an insulating and non-magnetic phase can be stabilized at strong coupling and sufficiently large frustrating ratio $t^\prime/t$.

description: Moving image art can provide unique possibilities for making sense of our surrounding reality. Consisting of a series of artworks produced through a creative research methodology, this thesis project explores wonderment and its role in visual perception. The series, Perceptual Moments, is comprised of short, evocative video works presented in a variety of modes including interactive and sculptural installation. To question the role of vision in mediating reality, the works engage the viewer through an intensive experience of seeing. This accompanying essay explores key visual and editing devices in the series that appear to have a role in shaping the viewer’s perception and interpretation of the visual experience, including “the chasm,” “the blur” and “interactive installation.” The essay also investigates the motivation behind the works through journal entries and offers critical analyses for each production. The visual devices in question are grounded within the context of psychology, neuroscience, phenomenology and film theories. Philosopher Gaston Bachelard provides an anchor for the concept of wonderment, while theorists Jonathan Crary and Gilles Deleuze create dialogical space around the act of viewing filmic images and the affect that it involves. The devices are also observed in other media works, including seminal pieces by Stan Brackhage, Kurt Kren and Jan Svankmajer as well as contemporary figures such as Nathalie Djurbergand Matt Hope.

description: TBK1 (TANK-binding kinase 1) is an essential receptor protein required for the innate immune response, but the mechanisms underlying TBK1 stability, especially those regulated via autophagy, remain poorly understood. Here, we demonstrate that USP19 (ubiquitin specific peptidase 19) interacts with and promotes TBK1 lysosomal degradation via chaperone-mediated autophagy (CMA). We observed that TBK1 had a canonical CMA motif, knocking down key proteins involved in CMA (HSPA8/HSC70 or LAMP2A) or inhibiting CMA-prevented USP19-mediated TBK1 degradation. Furthermore, USP19 deficiency in macrophages caused an elevation of TBK1 and the activation of the type-I interferon signaling pathway after vesicular stomatitis virus (VSV) infection. Consistently, macrophage-specific usp19 knockout in mice resulted in attenuated VSV replication and resistance to VSV infection in vivo. Altogether, our results suggest that USP19 is a key regulator of TBK1 and uncovers a previously uncharacterized role for USP19 in CMA-mediated TBK1 degradation and infectious diseases.
A Naked Lunch with the Modernists: Painting as Practice

Subjects: Cézanne--Artists--Modernism--Painting--Creative writing--Writing--Modern art

description: This thesis project intersects between both formal and creative writing styles that explore the potential of the written language to generate and promote material practice. Contextualizing contemporary painting both art historically and opening it up to broader range of influences such as memory systems and creative writing, all help to support my notion of painting as an open thinking model that acts as an oblique reply to both the everyday and art history. The thesis traces the reductive Modernist agenda with a particular focus on Australian art history, Dadaist diagrams and Modernist painting from 1958 to 1965; as an enquiry into the semiotics of gesture and the narrative potential of mark making. Working towards Post Modernism and how this has opened up the creative possibilities of painting now outside a critical and stylistic agenda. Through intersecting existing historical practices with more contemporary painters, I aim to suggest that painting is a practice that frequently looks to the past for answers, which subsequently leads my enquiry into various modes of appropriation Key notions through out the text are painting as a diagram and network, with Cezanne’s technique of ‘Passage shape,’ which I argue has had transitive effect throughout the course of modern art up to more contemporary practices such as Jutta Koether, who enacts the behavioral passage between objects in a range of multidisciplinary crossovers. This leads the enquiry into the transitive potential of animating these passage spaces with the semiotics of gesture and mark making.

description: Context: Analysis of ages and metallicities of star clusters in the Magellanic Clouds provide information for studies on the chemical evolution of the Clouds and other dwarf irregular galaxies. Aims: The aim is to derive ages and metallicities from integrated spectra of 14 star clusters in the Small Magellanic Cloud, including a few intermediate/old age star clusters. Methods: Making use of a full-spectrum fitting technique, we compared the integrated spectra of the sample clusters to three different sets of single stellar population models, using two fitting codes available in the literature. Results: We derive the ages and metallicities of 9 intermediate/old age clusters, some of them previously unstudied, and 5 young clusters. Conclusions: We point out the interest of the newly identified as intermediate/old age clusters HW1, NGC 152, Lindsay 3, Lindsay 11, and Lindsay 113. We also confirm the old ages of NGC 361, NGC 419, Kron 3, and of the very well-known oldest SMC cluster, NGC 121.

description: The performance of a Si PIN diode (type Hamamatsu S3590-06) as an energy sen- sitive detector operating at cryogenic temperatures (~10 K) and in magnetic fields up to 11 T was investigated, using a 207Bi conversion electron source. It was found that the detector still performs well under these conditions, with small changes in the response function being observed in high magnetic fields, e.g. a 30% to 50% decrease in energy resolution. A GEANT4 Monte Carlo simulation showed that the observed effects are mainly due to the modified trajectories of the electrons due to the influence of the magnetic field, which changes the scattering conditions, rather than to intrinsic changes of the performance of the detector itself.

description: This paper introduces the Austrian German sentiment dictionary ALPIN to account for the lack of resources for dictionary-based sentiment analysis in this specific variety of German, which is characterized by lexical idiosyncrasies that also affect word sentiment. The proposed language resource is based on Austrian news media in the field of politics, an austriacism list based on different resources and a posting data set based on a popular Austrian news media. Different resources are used to increase the diversity of the resulting language resource. Extensive crowd-sourcing is performed followed by evaluation and automatic conversion into sentiment scores. We show that crowd-sourcing enables the creation of a sentiment dictionary for the Austrian German domain. Additionally, the different parts of the sentiment dictionary are evaluated to show their impact on the resulting resource. Furthermore, the proposed dictionary is utilized in a web application and available for future research and free to use for anyone.

description: Capability planning problems are pervasive throughout many areas of human interest with prominent examples found in defense and security. Planning provides a unique context for optimization that has not been explored in great detail and involves a number of interesting challenges which are distinct from traditional optimization research. Planning problems demand solutions that can satisfy a number of competing objectives on multiple scales related to robustness, adaptiveness, risk, etc. The scenario method is a key approach for planning. Scenarios can be defined for long-term as well as short-term plans. This paper introduces computational scenario-based planning problems and proposes ways to accommodate strategic positioning within the tactical planning domain. We demonstrate the methodology in a resource planning problem that is solved with a multi-objective evolutionary algorithm. Our discussion and results highlight the fact that scenario-based planning is naturally framed within a multi-objective setting. However, the conflicting objectives occur on different system levels rather than within a single system alone. This paper also contends that planning problems are of vital interest in many human endeavors and that Evolutionary Computation may be well positioned for this problem domain.

description: Abstract

The goal of any economic system is to meet the demand of the population for food, goods and services. To achieve this goal, modern scientific and technical achievements are used in production in the national economy, measures are taken related to the effective organization of labor and a clear division of labor. The delivery of products produced in the conditions of market economic relations to consumers in the form of finished products is carried out through the management of economic relations in the sphere of commodity circulation. A large number of small and medium-sized enterprises in the food industry do not have sufficient financial resources to use modern technologies, as well as to improve the level of professional training of employees. For this reason, the delivery of food products to the consumer in the form of the final product on the market is expensive for society, the total costs of all stages of turnover are approximately equal to half of the final price of the goods. . All this allows economists to come to the conclusion that the positive impact of increasing the technological level and organization of production on the efficient use of resources should be accelerated. To do this, it is necessary to look for new reserve opportunities to increase efficiency in the rationalization of relations between production and consumption. It is for this reason that it should be noted that the issue of managing economic relations in the food market and improving the forms of movement of goods to the market, as well as the development of the food market, has become an urgent issue.

description: An increasing number of archival institutions aim to provide public access to historical documents. Ontologies have been designed, developed and utilised to model the archival description of historical documents and to enable interoperability between different information sources. However, due to the heterogeneous nature of archives and archival systems, current ontologies for the representation of archival content do not always cover all existing structural organisation forms equally well. After briefly contextualising the heterogeneity in the hierarchical structure of German archives, this paper describes and evaluates differences between two archival ontologies, ArDO and RiC-O, and their approaches to modelling hierarchy levels and archive dynamics.

We also carry out the explicit construction of the 3-form gauge fields and compare it with the geometry of 2--gerbes.

description: Motivated by a game of Battleship, we consider the problem of efficiently hitting a ship of an uncertain shape within a large playing board. Formally, we fix a dimension d ∈ {1, 2}. A ship is a subset of Zd. Given a family F of ships, we say that an infinite subset X ⊂ Zd of the cells pierces F, if it intersects each translate of each ship in F (by a vector in Zd). In this work, we study the lowest possible (asymptotic) density π(F) of such a piercing subset. To our knowledge, this problem has previously been studied only in the special case ∣F∣ = 1 (a single ship). As our main contribution, we present a formula for π(F) when F consists of 2 ships of size 2 each, and we identify the toughest families in several other cases. We also implement an algorithm for finding π(F) in 1D.

description: We incorporate hydrodynamic interactions (HI) in a coarse-grained and structure-based model of proteins by employing the Rotne-Prager hydrodynamic tensor. We study several small proteins and demonstrate that HI facilitate folding. We also study HIV-1 protease and show that HI make the flap closing dynamics faster. The HI are found to affect time correlation functions in the vicinity of the native state even though they have no impact on same time characteristics of the structure fluctuations around the native state.

Persistent Identifiers
Persistence

description: Here is the completed Mentimeter survey results from the PIDapalooza 2021 session entitled Putting the P in PIDs plus the script used for the session. Persistence is often taken for granted yet it is key for a sustainable research infrastructure. But what do we mean by persistence? Is it the identifier? The thing it identifies? Or the place where the thing lives? Or something else? Or all or some or none? This session will help the audience explore the famous 5 persistencies* and consider what identifier systems can do to guarantee persistence now and into the future. *https://andrew.treloar.net/research/diagrams/five_persistences.pdf

Barium lanthanum ferrate

description: High-resolution STEM-EELS provides information about the composition of crystalline materials at the atomic scale, though a reliable quantitative chemical analysis is often hampered by zone axis conditions, where neighbouring atomic column intensities contribute to the signal at the probe position. In this work, we present a procedure to determine the concentration of two elements within equivalent atomic columns from EELS elemental maps - in our case barium and lanthanum within the A-sites of Ba1.1La1.9Fe2O7, a second order Ruddlesden-Popper phase. We took advantage of the large changes in the elemental distribution from column to column and introduced a technique, which substitutes inelastic scattering cross sections during the quantification step by using parameters obtained from the actual experiment. We considered channelling / de-channelling effects via inelastic multislice simulations and were thereby able to count occupancies in each atomic column. The EELS quantification results were then used as prior information during the Rietveld refinement in XRD measurements in order to differentiate between barium and lanthanum.

Systemic Challenges

description: Facing the manifold sustainability challenges (GHG emissions, eutrophication, social welfare, etc.) in livestock farming, Digital Twins can help farmers to use available feed and nutrients efficiently, monitor livestock health, and control emissions to air, soil, and water. Combined with current precision livestock farming (PLF) technologies, Digital Twins (DT) enable real-time monitoring, simulation, and automation capabilities through real-world models and a two-way flow of information. As current applications are mostly focused on closed and highly regulated systems, this paper investigates the systemic challenges and associated design implications of DTs in complex PLF settings. By integrating a STES (social-technical-ecological system) design approach, the authors argue to foster design strategies that serve sustainable livestock governance and enable a sound and flexible basis for balancing associated engineering requirements such as privacy, security, ethics, and inclusion. We will use a qualitative assessment approach, discuss multidisciplinary requirements for Digital Twins, and consolidate them in a high-level road-map.

description: We report on the high pressure synthesis of BiMn$_7$O$_{12}$, a manganite displaying a "quadruple perovskite" structure. Structural characterization of single crystal samples shows a distorted and asymmetrical coordination around the Bi atom, due to presence of the $6s^{2}$ lone pair, resulting in non-centrosymmetric space group Im, leading to a permanent electrical dipole moment and ferroelectric properties. On the other hand, magnetic characterization reveals antiferromagnetic transitions, in agreement with the isostructural compounds, thus evidencing two intrinsic properties that make BiMn$_7$O$_{12}$ a promising multiferroic material.

An algorithm for the direct reconstruction of the dark matter correlation function from weak lensing and galaxy clustering

description: The clustering of matter on cosmological scales is an essential probe for studying the physical origin and composition of our Universe. To date, most of the direct studies have focused on shear-shear weak lensing correlations, but it is also possible to extract the dark matter clustering by combining galaxy-clustering and galaxy-galaxy-lensing measurements. In this study we develop a method that can constrain the dark matter correlation function from galaxy clustering and galaxy-galaxy-lensing measurements, by focusing on the correlation coefficient between the galaxy and matter overdensity fields. To generate a mock galaxy catalogue for testing purposes, we use the Halo Occupation Distribution approach applied to a large ensemble of N-body simulations to model pre-existing SDSS Luminous Red Galaxy sample observations. Using this mock catalogue, we show that a direct comparison between the excess surface mass density measured by lensing and its corresponding galaxy clustering quantity is not optimal. We develop a new statistic that suppresses the small-scale contributions to these observations and show that this new statistic leads to a cross-correlation coefficient that is within a few percent of unity down to 5 Mpc/h. Furthermore, the residual incoherence between the galaxy and matter fields can be explained using a theoretical model for scale-dependent bias, giving us a final estimator that is unbiased to within 1%. We also perform a comprehensive study of other physical effects that can affect the analysis, such as redshift space distortions and differences in radial windows between galaxy clustering and weak lensing observations. We apply the method to a range of cosmological models and show the viability of our new statistic to distinguish between cosmological models.

3D

description: This paper proposes a novel method for deep learning based on the analytical convolution of multidimensional Gaussian mixtures. In contrast to tensors, these do not suffer from the curse of dimensionality and allow for a compact representation, as data is only stored where details exist. Convolution kernels and data are Gaussian mixtures with unconstrained weights, positions, and covariance matrices. Similar to discrete convolutional networks, each convolution step produces several feature channels, represented by independent Gaussian mixtures. Since traditional transfer functions like ReLUs do not produce Gaussian mixtures, we propose using a fitting of these functions instead. This fitting step also acts as a pooling layer if the number of Gaussian components is reduced appropriately. We demonstrate that networks based on this architecture reach competitive accuracy on Gaussian mixtures fitted to the MNIST and ModelNet data sets.

description: A language L over a finite alphabet is growth-sensitive (or entropy sensitive) if forbidding any set of subwords F yields a sub-language L^F whose exponential growth rate (entropy) is smaller than that of L. Let (X, E, l) be an infinite, oriented, labelled graph. Considering the graph as an (infinite) automaton, we associate with any pair of vertices x,y in X the language consisting of all words that can be read as the labels along some path from x to y. Under suitable, general assumptions we prove that these languages are growth-sensitive. This is based on using Markov chains with forbidden transitions.

description: Homogeneous isotropic models built in the framework of the Poincaré gauge theory of gravity (PGTG) based on general expression of gravitational Lagrangian without cosmological constant are analyzed. It is shown that the physical spacetime in the vacuum in the frame of PGTG can have the structure of flat de Sitter spacetime with torsion. Some physical consequences of obtained conclusion are discussed.

We discuss the relationships between these duality relations and similar results for interacting many-body systems.

description: A long term, multi-wavelength monitoring campaign on the TeV binary LS I +61 303 has been performed utilizing >300 GeV observations with VERITAS along with monitoring in the 0.2-10 keV band by RXTE and Swift between September 2006 and February 2008. The source was detected by VERITAS as a variable TeV source with flux values ranging from 5-20% of the Crab Nebula flux with the strongest flux levels appearing around apastron. X-ray observations by RXTE and Swift show the source as a highly variable hard X-ray source with flux values varying in the range of 0.5-3*10^-11 ergs cm^-2 s^-1 over a single orbital cycle. The 2007-2008 RXTE data set also shows the presence of several extremely large flaring episodes presenting a flux of up to 7.2*10^-11 ergs cm^-2 s^-1, the largest such flare recorded from this source. Comparison of the contemporaneous TeV and X-ray data does not show a correlation at this time, however, the sparsity of data sets do not preclude the existence of such a correlation.
