description: Developing systems that can synthesize natural and life-like motions for simulated characters has long been a focus for computer animation. But in order for these systems to be useful for downstream applications, they need not only produce high-quality motions, but must also provide an accessible and versatile interface through which users can direct a character's behaviors. Natural language provides a simple-to-use and expressive medium for specifying a user's intent. Recent breakthroughs in natural language processing (NLP) have demonstrated effective use of language-based interfaces for applications such as image generation and program synthesis. In this work, we present PADL, which leverages recent innovations in NLP in order to take steps towards developing language-directed controllers for physics-based character animation. PADL allows users to issue natural language commands for specifying both high-level tasks and low-level skills that a character should perform. We present an adversarial imitation learning approach for training policies to map high-level language commands to low-level controls that enable a character to perform the desired task and skill specified by a user's commands. Furthermore, we propose a multi-task aggregation method that leverages a language-based multiple-choice question-answering approach to determine high-level task objectives from language commands. We show that our framework can be applied to effectively direct a simulated humanoid character to perform a diverse array of complex motor skills.

The Role of Spartina patens on U.S. Atlantic Dunes and Beaches: A Review, Examples from the North Carolina Coast, and Implications for Dune Building and Recovery
Creators: name: Ingram, Brianna Christine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Coastal foredunes, which arise from feedbacks between sediment transport and vegetation, protect coastal habitats and coastal development from storm impacts. The rate of dune growth and dune shape are influenced by the morphology of the dune-building grasses that give rise to them, because grass morphology determines the amount and location of sand capture. In this study, I focus on better understanding the role of Spartina patens, a species of beach and dune grass once considered to stabilize sediments and keep elevation low, but recently shown to be a moderate dune builder. I conducted a review of the natural history of S. patens along with an analysis of a longitudinal data set of co-collected topography and vegetation from the North Carolina coast to test a new hypothesis regarding the role of S. patens on beaches and dunes following storms. I found that S. patens occupies higher elevations than reported by earlier studies, likely a reflection of the broader range of beach and dune elevations encompassed in my data set compared to earlier studies that focused on S. patens in overwash areas due to its prevalence there. Consistent with earlier studies, I found a higher occurrence of S. patens on islands and transects that were more recently overwashed, likely due to the high salinity tolerance of this grass. How recently transects had been overwashed, along with dune elevation, are good predictors of where S. patens will be found: On younger/lower dunes S. patens is found primarily on the dune toe/face and heel, and on older/higher dunes S. patens is found almost exclusively on the heel. Based on my findings, I propose a new conceptual model in which S. patens, where present, plays an important role in initiating and speeding up the dune building process in its early stages. If this new conceptual model is correct, S. patens may provide value in restoration efforts that seek to accelerate the growth of natural dunes following overwash.

description: This dissertation investigates the use of the image of the home as image and subject in American art between 1960 and 1975, drawing connections between the social and political issues connected with housing, Civil Rights, the Woman's Movement, and the Cold War. Postwar representations of the American home were complex and multivalent, due, in part, to the housing crisis after World War II that was met by the suburbanization of the nation, and the newly energized postwar economy that brought the single-family, suburban home to the center stage of public and private life. As art historians have previously described, Abstract Expressionism created a masculine context for the American art world that excluded women and non-white, non-heterosexual male artists from creative agency. The decline of Abstract Expressionism gave rise to a re-engagement with images of domesticity, the home, and common objects of everyday life. Domesticity, seen as the anti-modern, played a significant role in the iconography of the male dominated field of Pop Art and also in the work of artists outside of the Pop stylistic umbrella. Representations of the American home, and its corollary, domesticity, appear frequently in the work of Roy Lichtenstein, Claes Oldenburg, James Rosenquist, and Tom Wesselmann; and in key works by Nancy and Ed Kienholz, Hans Haacke, Dan Graham, Martha Rosler, and Romare Bearden. Through an interdisciplinary approach to the material, the works of art themselves, I set the image and symbol of the American home within an art historical and contextual history that reveals a preoccupation with issues of domesticity, visibility and invisibility, theatricality, surface and depth, public and private space, and how space is structured and represented. Gender politics and the representation of women is an important subtext throughout this dissertation coming to center stage in the last chapter's examination of Judy Chicago and Miriam Schapiro's collaboration with the students of the Feminist Art Program at Cal Arts in 1971-72, Womanhouse. I argue that Womanhouse should be understood within the larger context of the 1960s interest in the home as a subject for art. Womanhouse was both a feminist rebuttal to the sequestering of the woman in the home and a reaction against the art world's pilfering of the domestic as a neo-dada, anti-art subject. Womanhouse re-colonized the interior of the home as a feminine and feminist space and reclaimed it as an active showcase of female creativity.

description: Horizon-based indirect illumination efficiently estimates a diffuse light bounce in screen space by analytically integrating the horizon angle difference between samples along a given direction. Like other horizon-based methods, this technique cannot properly simulate light passing behind thin surfaces. We propose the concept of a visibility bitmask that replaces the two horizon angles by a bit field representing the binary state (occluded / un-occluded) of N sectors uniformly distributed around the hemisphere slice. It allows light to pass behind surfaces of constant thickness while keeping the efficiency of horizon-based methods. It can also do more accurate ambient lighting than bent normal by sampling more than one visibility cone. This technique improves the visual quality of ambient occlusion, indirect diffuse, and ambient light compared to previous screen space methods while minimizing noise and keeping a low performance overhead.

description: Ubiquitous sensing devices frequently disseminate data among them. The use of a distributed event-based system that decouples publishers from subscribers arises as an ideal candidate to implement the dissemination process. In this paper, we present a network architecture that merges the network and overlay layers of typical structured event-based systems. Directional random walks are used for the construction of this merged layer. Our strategy avoids using a specific network protocol that provides point-to-point communication. This implies that the topology of the network is not maintained, so that nodes not involved in the system are able to save energy and computing resources. We evaluate the performance of the overlay layer using directional random walks and pure random walks for its construction. Our results show that directional random walks are more efficient because: (1) they use less nodes of the network for the establishment of the active path of the overlay layer and (2) they have a more reliable performance. Furthermore, as the number of nodes in the network increases, so do the number of nodes in the active path of the overlay layer for the same number of publishers and subscribers. Finally, we discard any correlation between the number of nodes that form the overlay layer and the maximum Euclidean distance traversed by the walkers.

DISPLACEMENT BLUES: AUTHENTICITY AND TRADITION AMIDST GENTRIFICATION AND COVID-19 IN NEW ORLEANS

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This collaborative patchwork ethnography explores responses to COVID-19 among senior Black blues and jazz musicians in New Orleans during the spring and summer of 2021. Across ethnographic conversations with members of this community, consultants articulated their experiences with tangible and intangible forms of displacement as the result of a complex interaction of natural and social processes including Hurricane Katrina, COVID-19, and gentrification. Ultimately, these forces of displacement and the changes they wrought upon New Orleans alienated our consultants from their means of making a living and from their ability to participate in and share New Orleans’ jazz and blues traditions with new and future audiences. COVID-19 provided a unique ethnographic context for our conversations with consultants which foregrounded their anxieties around tradition and authenticity, particularly in regard to the abrogation of their status as the performers of what they consider to be New Orleans’ authentic musical traditions: jazz and blues. Applying multiple theoretical and methodological frameworks for ethnographic fieldwork and interpretation to our consultants’ accounts reveals how interlocking conceptions of authenticity and tradition interact with our consultants’ social imaginaries of New Orleans to explain their accounts of social and cultural transformation in the Crescent City and the general decline in appreciation for blues and jazz performance they observe.

Denouncement, engagement and dialect

description: The genre of the mystery novel offers an ideal medium to analyze social injustice. The guise of criminal investigations allows for an examination of deviant behavior across diverse social strata and its causes and effects upon modern society. In theory, institutional justice in Italy extends equal rights and treatment to all citizens, irrespective of social standing or political affiliation. However, an analysis of criminal activity and the manner in which it is investigated and prosecuted reveals that this principle does not always hold true. These crimes--each a labyrinth of social and political connections, the daunting task of exposing those responsible and bringing them to justice within the framework of the legal system--constitute the plot of the Sicilian mystery novel. Despite the valiant and occasionally successful efforts of an investigator to solve these crimes, it is impossible to prosecute the guilty parties within the framework of the legal system. This break of the Sicilian mystery novel with the tradition of the genre prompted Italo Calvino to comment on "…the impossibility of the mystery novel within a Sicilian context" (Calvino, Foreword. To Each his Own). These mystery novels raise the question: What are the social phenomena unique to a Sicilian context that prevent institutionalized justice from being administered and what are the historical reasons responsible for such phenomena?When read as reflections of modern Sicilian society and the complex social problems that beleaguer it, the mystery novels of Leonardo Sciascia and Andrea Camilleri act as powerful tools of social denouncement. Through these novels their authors denounce the obscure web of connections and corruption that plagues not only Sicily but the Italian mainland as well. These mysteries reflect a society that is increasingly socially engaged, and they hint at the evolution of a collective moral consciousness in Sicily since Sciascia first published The Day of the Owl in 1961. This dissertation examines the innovative stylistic and thematic elements that make Sciascia and Camilleri’s literary contributions unique while reflecting the socially unjust cultural reality in which they were raised.

description: In this paper, a statistical model for the coupling of electromagnetic radiation into enclosures through apertures is presented. The model gives a unified picture bridging deterministic theories of aperture radiation, and statistical models necessary for capturing the properties of irregular shaped enclosures. A Monte Carlo technique based on random matrix theory is used to predict and study the power transmitted through the aperture into the enclosure. Universal behavior of the net power entering the aperture is found. Results are of interest for predicting the coupling of external radiation through openings in irregular enclosures and reverberation chambers.

description: Millions of smart contracts have been deployed onto the Ethereum platform, posing potential attack subjects. Therefore, analyzing contract binaries is vital since their sources are unavailable, involving identification comprising function entry identification and detecting its boundaries. Such boundaries are critical to many smart contract applications, e.g. reverse engineering and profiling. Unfortunately, it is challenging to identify functions from these stripped contract binaries due to the lack of internal function call statements and the compiler-inducing instruction reshuffling. Recently, several existing works excessively relied on a set of handcrafted heuristic rules which impose several faults. To address this issue, we propose a novel neural network-based framework for EVM bytecode Function Entries and Boundaries Identification (neural-FEBI) that does not rely on a fixed set of handcrafted rules. Instead, it used a two-level bi-Long Short-Term Memory network and a Conditional Random Field network to locate the function entries. The suggested framework also devises a control flow traversal algorithm to determine the code segments reachable from the function entry as its boundary. Several experiments on 38,996 publicly available smart contracts collected as binary demonstrate that neural-FEBI confirms the lowest and highest F1-scores for the function entries identification task across different datasets of 88.3 to 99.7, respectively. Its performance on the function boundary identification task is also increased from 79.4% to 97.1% compared with state-of-the-art. We further demonstrate that the identified function information can be used to construct more accurate intra-procedural CFGs and call graphs. The experimental results confirm that the proposed framework significantly outperforms state-of-the-art, often based on handcrafted heuristic rules.

description: Nanoelectronic devices that mimic the functionality of synapses are a crucial requirement for performing cortical simulations of the brain. In this work we propose a ferromagnet-heavy metal heterostructure that employs spin-orbit torque to implement Spike-Timing Dependent Plasticity. The proposed device offers the advantage of decoupled spike transmission and programming current paths, thereby leading to reliable operation during online learning. Possible arrangement of such devices in a crosspoint architecture can pave the way for ultra-dense neural networks. Simulation studies indicate that the device has the potential of achieving pico-Joule level energy consumption (maximum 2 pJ per synaptic event) which is comparable to the energy consumption for synaptic events in biological synapses.

DETERMINING CARBON SEQUESTRATION IN RESERVOIRS: A QUANTITATIVE  210Pb-BASED APPROACH
Creators: name: Booth, Morgan Scott
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: As carbon emissions continue to rise, efforts have increased to properly quantify carbon sources and sinks in response to increasing atmospheric CO2 concentration. Some major carbon sinks, like lakes and blue carbon environments, have seen massive efforts undergone to quantify their role in the global carbon cycle. Others, like reservoirs, have been chronically understudied and poorly accounted for as carbon sequestration environments. Using precise and rigorous 210Pb geochronologies, we calculated carbon burial rates at eight locations within Falls Lake, a reservoir in North Carolina. These values ranged from 42 g C m-2y-1 to 1139 g C m-2y-1 with a mean of 313 g C m-2y-1. These values are comparable to carbon accumulation rates reported in blue carbon environments and demonstrate the high potential of reservoirs as an effective yet overlooked carbon sequestration environment.

Han, Hui, and Black Oppression and Renewal: Intellectual Histories to Challenge Racist Narratives of Regression

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Liang Qichao, Bai Shouyi, and Zora Neale Hurston wrote ethnic, origin histories for their respective groups in the early twentieth century. At first glance, it is easy to conclude that these non white intellectuals were affected by the Darwinist, racialist ideology of their time such that their histories mirrored the exclusionist development of nationalism. In this work, evidence of strategies for autonomy, integration and planning for the later success of their respective ethnic group is analyzed in Histories of Chinese Political Thought during the Early Qin Period, A Short History of Islam in China, and Barracoon. All three historians, through pointing to an episode of oppression and showing its effects on Han, Hui, and Black Americans, pine for a modernity that looks different from both the modernity we have experienced and the modernity nationalist intellectuals touted for the world.

A CENTURY OF DISTURBANCE: HOW ANTHROPOGENIC MODIFICATION HAS AFFECTED SEDIMENT ACCUMULATION PATTERNS IN THE COOS ESTUARY DURING THE LAST 100 YEARS
Creators: name: Souza, Tyler Davis
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Estuaries across the United States have been extensively modified by development in their watersheds. Anthropogenic modification in the Coos Estuary (Oregon) includes cycles of silviculture, installation of jetties, and dredging and rerouting of the main channel. To better understand how these changes affected estuarine sediment dynamics, a series of cores were collected from intertidal flats across the estuary. Sediment dating utilizing 210Pb radio spectroscopy revealed wide variability in sedimentation rates. Small channel-edge tidal flats generally appear to be accumulating sediment at ~0.10 cm/yr or roughly the rate of relative sea lever rise (RSLR). Large intertidal flats accumulated sediment at rates faster than RSLR, exhibited peaks in sedimentation lasting several years, and showed substantial increases in sediment accumulation in the 20th century with mean rates for the last 50 years up to 1.5 cm/yr. These results provide insights for restoration of native species and estuarine management in the 21st century.

description: Computer science (CS) has historically struggled with issues related to diversity, equity, and inclusion (DEI). Based on how these issues were affecting PhD students in our department, we identified required DEI education for PhD students as a potentially high-impact approach to improving the PhD student experience in our program. Given that no existing curriculum met the desired criteria, we (PhD students) - along with many others at our school - developed and implemented CS-JEDI: Justice, Equity, Diversity, and Inclusion in Computer Science. CS-JEDI is a 6-week DEI curriculum that is now taken by all first-year PhD students in our department. This paper covers CS-JEDI's motivation and goals; describes how its evidence-based curriculum is tailored to these goals and to the CS PhD context; and gives a data-driven evaluation of the extent to which CS-JEDI's first offering, in Spring 2022, achieved these goals.

description: Recent progress of Reciprocal Quantum Logic (RQL) has renewed interest in AC powering of superconductor digital circuits, which had been abandoned since the famous IBM project of 1970s. In this work we propose and demonstrate new AC-biased Single Flux Quantum (SFQ) circuits, and search for synergy of AC and currently dominating DC biasing schemes. As the first step, we suggest an on-chip AC/DC converter capable of feeding a few DC-biased gates surrounded by their AC-biased counterparts. As the second step, we introduce and present the first successful demonstration of a new AC-powered circuit - an 8192-bit shift register with over 32,800 Josephson junctions (JJs) and JJ density of about 6x$10^5$ JJ per $cm^2$. We suggest a few niche applications for this type of AC-biased circuits, not requiring high clock rates. E.g., these, scalable to millions of JJs per chip, circuits can serve as a convenient benchmark for new SFQ fabrication technology nodes, allowing the operating margins of individual cells to be extracted and, thus, 'visualize' individual fabrication defects and flux trapping events. The circuit can also be developed into a mega-pixel imaging array for a magnetic field microscope.

description: Purpose: To determine the research output of Caribbean nurses and midwives. Methods: We searched the Scopus database to identify publications by Caribbean nurses and midwives during the period 2000–2020. Publications were included in the analysis if they had at least one author who was either a nurse or midwife and affiliated with a Caribbean geographic location. All publication types and languages were included in the analysis. Organization analysis and collaboration networks were created using the VOS Viewer application. Findings: The number of Scopus publications by Caribbean nurses and midwives progressively grew from 22 in 2000 to 584 in 2020. Cuba recorded the highest number of nursing research publications (319) followed by Jamaica (92), and Puerto Rico (59). Most publishing institutions were universities. The University of the West Indies (Jamaica) ranked highest with 15.2% of publications, followed by Universidad de Ciencias Médicas de La Habana with 14.4% of publications, Universidad de Puerto Rico ranked third with 9.8% of publications. The majority of publications (83.6%) were peer reviewed research articles, while review articles accounted for 9.8% of publications. Six out of the ten journals that published most research done by Caribbean nurse researchers were Cuban journals which published a total of n = 250 (75.8%) articles. All six journals had no impact factor and had low cite scores. Conclusions: Our analysis of bibliometric indicators suggest that recent and steady growth in nursing and midwifery research in the Caribbean has had low visibility. Equipping nurses and midwives with the necessary knowledge and skills to lead, teach, and conduct high quality research through doctorate level education is an imperative for increasing research productivity among Caribbean nurses and midwives. Clinical relevance: Nursing and midwifery research is critical for evidence-based nursing and midwifery practice. High quality and context specific research evidence will enable Caribbean nurses and midwives to provide quality and culturally sensitive nursing and midwifery care and contribute to evidence informed policy decisions.

description: We report here an atomistic study of the mechanical deformation of AuxCu(1-x) atomic-size wires (NWs) by means of high resolution transmission electron microscopy (HRTEM) experiments. Molecular dynamics simulations were also carried out in order to obtain deeper insights on the dynamical properties of stretched NWs. The mechanical properties are significantly dependent on the chemical composition that evolves in time at the junction; some structures exhibit a remarkable de-alloying behavior. Also, our results represent the first experimental realization of mixed linear atomic chains (LACs) among transition and noble metals; in particular, surface energies induce chemical gradients on NW surfaces that can be exploited to control the relative LAC compositions (different number of gold and copper atoms).

"Not regularly musical"
Creators: name: Manhire, Vanessa
Publisher: name: No Publisher Supplied

description: While the visual arts have long been a focus of inquiry in Woolf criticism, attention has only recently been drawn to the potential influence of music--a fact which is all the more surprising since in her letters Woolf claimed "I think of all my books as music before I write them" (L6 426) and discussed her desire "to investigate the influence of music on literature" (L6 450). Woolf's acknowledged interest in interdisciplinary approaches to literature, her love of music, and her assumed position as a "common listener" rather than an expert, make her the ideal subject for a study of literary writing about music. This study has two overlapping focuses: Woolf's thoughts about the relationship between music and literature, and the variety of ways in which she represents the activities of making and listening to music in her writings, both fiction and non-fiction. My dissertation argues that Woolf's changing thinking about music affects both the form and content of her entire oeuvre.Chapter One looks at Woolf's early essays on musical topics, arguing that her investigations into the nature and status of music as an art form played an important part in the formation of her own literary project. Chapter Two focuses on her representations of women musicians and scenes of musical performance in her early fiction. Woolf's depictions of music as a medium which appeals simultaneously to interiority and exteriority indicate its direct influence on her development of stream-of-consciousness narrative techniques. Chapter Three shows that the preponderance of criticism which dubs Woolf's novels "musical" in form actually ignores the vexed questions of voice and form implicit in Woolf's own novelistic representations of song: the lyric interruptions caused by such musical scenes serve not to symbolize, but rather to disturb, the idea of formal unity. Chapter Four looks at the increasingly complex figurations of music in Woolf's late work alongside the rhetoric of the English Folk Revival: Woolf both responds to new sound technologies and interrogates the vexed concepts of English history and national identity.

The cyber-framing of Nigerian nationhood
Creators: name: Odutola, Kole Ade
Publisher: name: No Publisher Supplied
Year: 2010

description: Postings generated during 'natural' online interactions among geographically dispersed/ diasporic Nigerians contain ideas from different intellectual sources. A few of the ideas encapsulated within texts produced were brought to the fore, discussed, and analyzed. The consequent search for the presence of indigenous knowledge within the postings produced a promise not a substantial product that can be circulated within the discipline of new media studies.The chosen method of analysis subjected online conversations and reflections to close readings aimed at extracting contextual and inter-textual meanings. This study also expands on the fundamental question raised by Misty Bastian in relation to how absence of physical constraints (and potential violence) is reflected in nationalist discourse. I argued that freedom from physical constraints and potential violence has been replaced by norms, novelties of virtual spaces, dominance of Western paradigms and epistemological shackles imposed by technology now act as the barriers to nationalist cyber-discourse. Textual analysis reveals that Nigerians draw extensively from a broad spectrum of ideas, but most significantly from notions emanating from Europe and America. In addition, Western notions like nationalism, nationhood, and state can hardly be differentiated in the consciousness of some contributors. This study presents traces of hegemony of Western ideas in postings and conversations online. Nigeria's presence as a postcolonial nation (or nation space) is established online through various activities of citizens at home and in the diaspora. These communicative activities and political activism have led to a wide range of scholarly interrogations and interventions in media, communication and migration studies against the backdrop of globalization, democratization, and modernization theories. It has been amply documented that communication and social interaction produce ideas that can be evaluated along the lines of deliberative democracy. These approaches have produced outcomes without the benefit of the complex debates, dialogues, and disagreements that come with popular participation and creation of variegated knowledge by a collective. I conclude that the concept of nationhood is not fixed but it a symbolic construct that evolves through unstructured conversations, sharing, and intense debates.

description: We report on the discovery of the C7N- anion towards the starless core TMC-1 and towards the carbon-rich evolved star IRC+10216. We used the data of the QUIJOTE line survey towards TMC-1 and found six lines in perfect harmonic frequency relation from J=27-26 up to J=32-31. The frequency of the lines can be reproduced with a rotational constant and a distortion constant of B=582.68490+/-0.00024 MHz and D=4.01+/-0.13 Hz, respectively. The standard deviation of the fit is 4 kHz. Towards IRC+10216, we identify 17 lines from J=27-26 up to J=43-42; their frequencies are also in harmonic relation, providing B=582.6827+/-0.00085 MHz and D=3.31+/-0.31 Hz. The nearly exact coincidence of the rotational and distortion constants in both sources points unambiguously to a common molecular carrier. Taking into account the chemical peculiarities of both sources, the carrier could be a radical or an anion. The radical can be discarded, as the observed lines belong to a singlet species. Hence, the most plausible carrier is an anion. High-level ab initio calculations indicate that C7N-, for which we compute a rotational constant of B=582.0 MHz and a dipole moment of 7.5 D, is the carrier of the lines in both sources. We predict the neutral C7N to have a ground electronic state 2Pi and a dipole moment around 1 D. Because of this low dipole moment value and to its much larger rotational partition function, its lines are expected to be well below the sensitivity of our data for both sources.

description: This work provides a general overview for the treatment of symmetries in classical field theories and (pre)multisymplectic geometry. The geometric characteristics of the relation between how symmetries are interpreted in theoretical physics and in the geometric formulation of these theories are clarified. Finally, a general discussion is given on the structure of symmetries in the presence of constraints appearing in singular field theories. Symmetries of some typical theories in theoretical physics are analyzed through the construction of the relevant multimomentum maps which are the conserved quantities (by Noether's theorem) on the (pre)multisymplectic phase spaces.

Interplanetary Propagation Behavior of the Fast Coronal Mass Ejection from 23 July 2012

description: The fast coronal mass ejection (CME) from 23 July 2012 raised attention due to its extremely short transit time from Sun to 1 AU of less than 21 h. In-situ data from STEREO-A revealed the arrival of a fast forward shock with a speed of more than 2200 km s$^{-1}$ followed by a magnetic structure moving with almost 1900 km s$^{-1}$. We investigate the propagation behavior of the CME shock and magnetic structure with the aim to reproduce the short transit time and high impact speed as derived from in-situ data. We carefully measure the 3D kinematics of the CME using the graduated cylindrical shell model, and obtain a maximum speed of 2580$\pm$280 km s$^{-1}$ for the CME shock and of 2270$\pm$420 km s$^{-1}$ for its magnetic structure. Based on the 3D kinematics, the drag-based model (DBM) reproduces the observational data reasonably well. To successfully simulate the CME shock, we find that the ambient flow speed should be of average value close to the slow solar wind speed (450 km s$^{-1}$), and the initial shock speed at a distance of 30 $R_{\odot}$ should not exceed $\approx$2300 km s$^{-1}$, otherwise it would arrive much too early at STEREO-A. The model results indicate that an extremely low aerodynamic drag force is exerted on the shock, smaller by one order of magnitude compared to the average. As a consequence, the CME hardly decelerates in interplanetary space and maintains its high initial speed. The low aerodynamic drag can only be reproduced when reducing the density of the ambient solar wind flow, in which the massive CME propagates, to $ρ_{\rm sw}$=1-2 cm$^{-3}$ at the distance of 1 AU. This result is consistent with the preconditioning of interplanetary space owing to a previous CME.
