description: We present a practical solution to create a relightable model from Multi-light Image Collections (MLICs) acquired using standard acquisition pipelines. The approach targets the difficult but very common situation in which the optical behavior of a flat, but visually and geometrically rich object, such as a painting or a bas relief, is measured using a fixed camera taking few images with a different local illumination. By exploiting information from neighboring pixels through a carefully crafted weighting and regularization scheme, we are able to efficiently infer subtle per-pixel analytical Bidirectional Reflectance Distribution Functions (BRDFs) representations from few per-pixel samples. The method is qualitatively and quantitatively evaluated on both synthetic data and real paintings in the scope of image-based relighting applications.

description: We present lattice QCD results for the screening masses of light mesons and charmonia. The lattice computations were performed with 2+1 flavors of improved staggered quarks using quark masses which correspond to realistic pion and kaon masses at zero temperature. For the light quark sector we have found that the screening masses in the pseudo-scalar and the isovector scalar channels do not become degenerate at the chiral crossover temperature indicating an effective non-restoration of the axial symmetry. Also the splitting between the vector and the pseudo-scalar screening masses persists even in the limit of zero lattice spacing and at a moderately high temperature around 420 MeV. In the charmonium sector our investigation shows that the screening masses of the pseudo-scalar and the vector charmonia are almost (within a few percent) equal to their zero temperature masses for temperatures less than 300 MeV. We also present results for the charmonium screening masses using periodic boundary conditions along the temporal direction and discuss their implications.

Hadronic Spectrum - Multiquark States

description: Many newly discovered mesons behave like $\ccbar$ charmonium states in that they preferentially decay into final states that contain a $c$- and a $\bar{c}$-quark, but do not fit expectations for any of the unfilled levels of the conventional $\ccbar$ spectrum. There is a growing suspicion that at least some of these states are {\it exotic}, {\it i.e.} have a substructure that is more complex than the quark-antiquark mesons of the classical constituent quark model. Some of these candidate states have a non-zero electric charge and, thus, a minimal quark content of $\ccbar u\bar{d}$ or $\ccbar d\bar{u}$. In addition, states with similar properties have been observed in the $b$- and $s$-quark sectors. In this report, the experimental situation is briefly reviewed.

description: In this Letter, we report the discovery of a new bright radio transient in M82. Using the Very Large Array, we observed the nuclear region of M82 at several epochs at 22 GHz and detected a new bright radio source in this galaxy's central region. We find a flux density for this flaring source that is ~300 times larger than upper limits determined in previous observations. The flare must have started between 2007 October 29 and 2008 March 24. Over the last year, the flux density of this new source has decreased from ~100 mJy to ~11 mJy. The lightcurve (based on only three data points) can be fitted better with an exponential decay than with a power law. Based on the current data we cannot identify the nature of this transient source. However, a new radio supernova seems to be the most natural explanation. With it's flux density of more than 100 mJy, it is at least 1.5 times brighter than SN1993J in M81 at the peak of its lightcurve at 22 GHz.

description: We report anisotropic thermal expansion of the parent, AEFe2As2 (AE = Ba, Sr, and Ca), compounds. Above the structural/antiferromagnetic phase transition anisotropy of the thermal expansion coefficients is observed, with the coefficient along the a-axis being significantly smaller than the coefficient for the c-axis. The high temperature (200 K < T < 300 K) coefficients themselves have similar values for the compounds studied. The sharp anomalies associated with the structural/antiferromagnetic phase transitions are clearly seen in the thermal expansion measurements. For all three pure compounds the "average" a-value increases and the c-lattice parameter decreases on warming through the transition with the smallest change in the lattice parameters observed for SrFe2As2. The data are in general agreement with the literature data from X-ray and neutron diffraction experiments.
Impact of rapid transit stations on land use changes in their proximity

Publisher: name: University of British Columbia

description: For nearly one hundred years, from approximately the 1830s to the early decades of the twentieth century, the form of many North American cities was dominated by the pattern of mass transportation routes. Each successive form of transportation from the horse drawn omni-bus to the electric street railways, had visible effects upon the growth, shape and internal organization of urban agglomerations. After fifty years of almost sole reliance on private transportation, the last decade has witnessed a significantly increased interest in rail rapid transit with an often claimed, but rarely thoroughly analyzed expectation, that the revitalized and improved mass transportation routes will ultimately piece the fragmented environment of today's metropolises into a manageable whole again. This study treats one aspect of the multi-dimensional interaction between the introdution/ operation of rapid transit lines and subsequent restructuring of the spatial distribution of activities in the urban field: the rate of development of areas in the proximity of rapid transit stations. Explanations for the aparent difference in the rate of new construction around various stations is sought not in terms of the traditional accessibility concept, but rather in the environmental context within which each station is placed. Drawing from a rather distinct subdivision of urban research and extensive data analysis, the components of the environmental context and their relative importance in exerting influence on the spatial distribution of new construction were identified. During the course of the study a simple simulation model was developed in order to capture the dynamics of changes within the environmental context and consequently to assist in anticipating the spatial distribution of new constructions or replacements of existing phyisical stock in the vicinity of rapid transit stations. The emphasis is placed on these specific structural changes because the consequences of locational and investment decisions that result in significant alteration or renewal of buildings represent a more substantial modification in the internal organization of the city than those resulting from the continuous shifting and filtering of activities within the standing stock.

A previous study reported shaft deformation differences due to club kick-point changes, subsequently impacting perceptual assessment. However, the relationship between perceptual assessment and swinging motion is obscure. To address this gap, the primary objective of this study is to analyze the mechanics of golf-swing motion.
Rape or romance? : sexual violence and the lust for power in Ovid's Fasti
Creators: name: Mckay, A
Publisher: name: University Of Tasmania
Year: 2023

description: Until the late Twentieth Century Fasti was arguably Ovid's least favoured extant work. Fasti was extensively compared with Ars Amatoria and Metamorphoses and in light of these comparisons was considered to be stylistically and artistically weak. This text has been interpreted as a jumbled compilation of history, astronomy and quasi-Callimachean poetics. From an historical and anthropological point of view, the work is a failure; for despite purporting to deliver reliable and thorough information on Roman cults and festivals (Fast. 1. 1-2), the information is often convoluted and inaccurate. Critics condemned the work as one that fails artistically. Fasti had consistently been interpreted as a badly written pro-Augustan poem. Such readings significantly over-simplified the text. These interpretations saw Fasti reduced to its alleged purpose. Ovid's Fasti is a calendar unlike any other. It is a poem written in six books corresponding to the first six months of the Julian calendar. Within this work Ovid engages in a dialogue with Augustus to contest the emperor's manipulation of time. Fasti is not simply a day by day commentary on Roman rituals and festivals. There are complex social and imperial implications found within this text. Recent scholarship began to embrace the poem's eccentricities and intricacies. Newlands suggested Fasti experienced something of a 'critical renaissance'. No longer is Fasti viewed as a failed literary calendar. The text has been opened up to reveal layers and depth of literary allusion and subtlety, allowing a deeper understanding of the poet's critique of the Augustan political regime. The position taken in this thesis is that Ovid's Fasti is a poem about Rome. It is my opinion that Ovid wrote Fasti as much more than a historical and mythological treatise on the events of the Roman calendar. This thesis will show that Fasti was written as a commentary and critique of Ovid's contemporary Rome and of its ruler Augustus just as much, or perhaps even more so, than it was a description of the nation's aetiological past. The Fasti contains a wealth of history, legend, astronomy and some historical fact. It also contains allusion and at times blatant observations about the current state of Roman politics. Fasti is a poem about Rome. It is a poem about the Rome of the poet's past and that of his present.

description: We explore potential of current and next-generation gamma-ray telescopes for the detection of weak magnetic fields in the intergalactic medium. We demonstrate that using two complementary techniques, observation of extended emission around point sources and observation of time delays in gamma-ray flares, one would be able to probe most of the cosmologically and astrophysically interesting part of the "magnetic field strength" vs. "correlation length" parameter space. This implies that gamma-ray observations with Fermi and ground-based Cherenkov telescopes will allow to (a) strongly constrain theories of the origin of magnetic fields in galaxies and galaxy clusters and (b) discover, constrain or rule out the existence of weak primordial magnetic field generated at different stages of evolution of the Early Universe.

description: In this project we are investigating the requirements to ease interdisciplinary collaboration between computer graphics researchers and heritage-related researchers who work with shared graphics-related datasets. We postulate that most challenges can be overcome by ensuring that datasets (irrespective of discipline) are captured, processed and disseminated in ways that accommodate the needs of as many disciplines as possible - making the datasets more useful and more usable. This is not to say that a union of all discipline methodologies is required, but instead: we deem it necessary to identify what changes are feasible in existing (discipline-centric) practices to maximise the benefits, while limiting resource costs. The purpose of this paper is to begin this conversation, present our project, preliminary results and where the project will go next. We also propose the outline of an interdisciplinary, peer-reviewing framework that can be used across disciplines.

Land reforms and poverty : the impacts of land reforms on poor land users in the Nkoranza South Municipality, Ghana
Creators: name: Anaafo, D
Publisher: name: University Of Tasmania
Year: 2023

description: The Government of Ghana began the implementation of the Land Administration Project (LAP) in 2003 as an effort to elaborate on the broad thrusts of the National Land Policy (NLP), which was approved in January 1999. The LAP focuses on facilitating access to land, ensuring security of title to land and enhancing institutional capacity for efficient and effective land administration. A decade into the implementation of the NLP and LAP this study sought to examine the impacts of land reforms on the land access, use rights and livelihoods of poor land users. The study uses field data gathered through in-depth interviews, observations and focus group discussions from the Nkoranza South Municipality (NSM) to explore the ability of women farmers, pastoralists and migrant farmers to access, use and manage land resources under the emerging agency system‚ÄövÑvp of land governance. The study also examined the regimes governing land access and use of the commons for grazing by pastoralists. The study establishes that although communal dynamics play a role in shaping land rights changes, current changes in land rights are the result of a land reform system that exposes close-knit communal land resources to metropolitan capital investments and transnational land deals. It further indicates that land reforms, pursued as silo developmental interventions, as is the case of the NSM case study, are incapable of alleviating poverty and the multiple livelihood needs of the poor. As such, it is recommended that land reforms be pursued as part of integrated development interventions, if poverty reduction remains a relevant goal of such initiatives. Furthermore, evidence from the field data suggests that the Nkoranza cosmovision of land as exhibiting features of a gift, a commodity and a sacred object should constitute the defining variables in any attempt to create locally viable land tenure systems. This entails incorporating the customs of the local people into the land reform processes. Finally, it is pointed out that state policies over land should seek to sustain communal practices, land use dynamics and cultures by supporting land tenure stabilisation and increasing voice and accountability over land use decision making.

description: We investigate the dynamics of DNA translocation through a nanopore driven by an external force using Langevin dynamics simulations in two dimensions (2D) to study how the translocation dynamics depend on the details of the DNA sequences. We consider a coarse-grained model of DNA built from two bases $A$ and $C$, having different base-pore interactions, {\textit e.g.}, a strong (weak) attractive force between the pore and the base $A$ ($C$) inside the pore. From a series of studies on hetero-DNAs with repeat units $A_mC_n$, we find that the translocation time decreases exponentially as a function of the volume fraction $f_C$ of the base $C$. %($ε_{pC} < ε_{pA}$). For longer $A$ sequences with $f_C \le 0.5$, the translocation time strongly depends on the orientation of DNA, namely which base enters the pore first. Our studies clearly demonstrate that for a DNA of certain length $N$ with repeat units $A_mC_n$, the pattern exhibited by the waiting times of the individual bases and their periodicity can unambiguously determine the values of $m$, $n$ and $N$ respectively. Therefore, a prospective experimental realization of this phenomenon may lead to fast and efficient sequence detection technic.

Direct Elastic Unrollings of Painted Pottery Surfaces from Sparse Image Sets

description: An important task in archaeological research is the comparison of painted motifs on ancient vessels and the analysis of their painting style. Ideally, the pottery objects are available as scanned 3D models, from which the painted surface can be unrolled and potential distortions minimized, so that the vase painting and its individual motifs can be directly inspected. Unfortunately, the percentage of digitally captured vessels is small compared to the large body of cataloged photographs. In this paper, we present a method that creates distortion-minimized unrollings of painted pottery surfaces directly from a small set of photographs. We achieve this by exploiting prior knowledge about the data, namely that most objects exhibit rotational symmetry and that strict guidelines were followed when capturing photographs of the ancient vases. Based on the distinctly visible object silhouettes in the photographs we are able to extract proxy geometries of the objects which we encode as per-view geometric maps. By stitching the single-view data, we obtain a combined map capturing the geometry and texture of the entire painted surface. This enables us to minimize typical projective distortions by elastic relaxation. Our pipeline works entirely in 2D image space, circumventing time-consuming 3D scans and surface reconstructions of (often inaccessible) vessels. Using a combination of CPU-based image processing and GPU-based relaxation, results are produced in only a few minutes.

description: A large number of complex systems find a natural abstraction in the form of weighted networks whose nodes represent the elements of the system and the weighted edges identify the presence of an interaction and its relative strength. In recent years, the study of an increasing number of large scale networks has highlighted the statistical heterogeneity of their interaction pattern, with degree and weight distributions which vary over many orders of magnitude. These features, along with the large number of elements and links, make the extraction of the truly relevant connections forming the network's backbone a very challenging problem. More specifically, coarse-graining approaches and filtering techniques are at struggle with the multiscale nature of large scale systems. Here we define a filtering method that offers a practical procedure to extract the relevant connection backbone in complex multiscale networks, preserving the edges that represent statistical significant deviations with respect to a null model for the local assignment of weights to edges. An important aspect of the method is that it does not belittle small-scale interactions and operates at all scales defined by the weight distribution. We apply our method to real world network instances and compare the obtained results with alternative backbone extraction techniques.

description: In this paper we report about the photogrammetric acquisition and reconstruction of a contemporary artwork, performed by offthe- shelf software. The ceramic piece of art is "Il Libro d'Oro del Terzo Paradiso" ("The Golden Book of the Third Paradise") by Michelangelo Pistoletto, accessed and studied in the framework of a regional project. This artefact is particularly challenging. On the one hand, it is golden coated and, as such, highly reflective. Hence, images are likely to suffer from highlight spots, shadows or self-reflections, and the reconstructed point cloud is typically noisy. On the other hand, the object exhibits simple geometry, mainly composed of planar surfaces, and is highly symmetric; however, it possesses detail features and undercuts. The symmetric nature of the object and reflections misled the image alignment, and the noise in the data turned out to be of the same scale as the detail features. We will discuss all the steps of the process, aimed at obtaining a high quality and accurate 3D model using low-cost tools.

A study of the effect of product information cues on consumers' purchase decision-making of unknown brands
Creators: name: Bai, X
Publisher: name: University Of Tasmania
Year: 2023

description: China is rapidly becoming an important market for consumer goods. Though branding across a number of product categories in the context of the Chinese market is well studied, relatively little is known about how consumers respond to products carrying brands that are neither known nor familiar with. In order to address this gap of research, the purpose of this study is to gain an insight into how Chinese consumers utilise product attribute cues to evaluate product quality and their intention to purchase, particularly towards unknown brands. Through a review of relevant theories and literature, this study comprehensively identified and analysed all major external product cues which may directly influence consumers' perception towards unknown brands. In particular, this study created a multi-cue situation to understand consumers' decision-making process with all product cues presented to consumers simultaneously for consumers to evaluate. Field experiment was employed and the data was analysed using conjoint analysis and 2x2x2x2 factorial design. The results of the experiment indicated that price similarity and package similarity, among all other external factors, exhibited the highest level of influence in consumers purchase decision-making under the shopping context. Retailer image exhibited moderate level of influence in the decision-making process while third party organisation endorsement does not show significant influence. Significant interaction effect was also found between price similarity and package similarity indicating the congruence signal of external cues also affect consumers decision-making significantly. This research contributes by extending the application of existing cue utilisation theory to the context of unknown brands. By combining signalling theory and assimilation/contrast theory, this research proposed two unique external product cues that were critical to consumers' decision-making process but largely neglected by previous studies. This research highlights that it is important for marketers to understand how to manipulate external product cues to shift the position of their brands into consumers evoked set. In addition to this, it is important for marketers to know the investment towards which external factors are most cost-effective and can make their brands stand out‚ÄövÑvp easier and sooner. Furthermore, this research suggests that marketers are required to ensure the external product cues are sending consistent signals to enhance the positive effect of cue manipulation.

No magnetic XMCD contrast was observed at the Cu L$_3$ absorption edge, which should directly image the spin accumulation in Cu. Although electrical transport measurements in a non-local geometry clearly detected the spin accumulation in Cu, which remained unchanged during illumination with circular polarized x-rays at the Co and Cu L$_3$ absorption edges.

After using a highly flexible $B$-Spline $R$-matrix method to generate field-free Hamiltonian and electric dipole matrices, the initial state is propagated in time using an efficient Arnoldi-Lanczos scheme. Test calculations for double ionization of He by a single laser pulse yield good agreement with benchmark results obtained with other methods. The method is then applied to two-color pump-probe processes, for which momentum and energy distributions of the two outgoing electrons are presented.

description: Research data management (RDM) has become a core aspect of research, especially since the establishment of the FAIR-Principles (Wilkinson et al. 2016) and comprehensive infrastructure projects, e.g. the National Research Data Infrastructure (NFDI). Besides several helpdesk services of the NFDI consortia, Universities have founded local generic RDM counseling units and domain-specific RDM centers as primary facilities that support researchers in questions regarding RDM and offer RDM (infrastructure) services.

However, large research programs (such as collaborative research centers and transregios, research training groups, excellence clusters and priority programs) often organize their RDM independently of these RDM centers through designated staff. Core aspects of this self-managed RDM are a profound knowledge of domain-specific RDM requirements and the cooperation with different stakeholders and RDM networks, like computing centers and infrastructure projects.

In our talk, we will present the RDM unit of the priority program SPP 2207 “Computational Literary Studies” funded by the German Research Foundation (DFG). We will focus on approaches of measuring RDM requirement landscapes, how our work helped us identify domain-specific RDM requirements and address them together with other RDM infrastructures and initiatives.

description: The minimal SU(5) theory augmented by the fermionic adjoint representation restores the coupling constant unification and gives realistic neutrino masses and mixing through the hybrid Type I and Type III seesaw. The crucial prediction of the theory is an SU(2) lepton triplet with the mass below TeV. We study the signature of these heavy leptons and propose the strategy to test this mechanism at the hadron and lepton colliders. The smoking gun evidence of the theory is Delta L=2 lepton number violation through events of a pair of like-sign leptons plus four jets without significant missing energy at hadron colliders. We find that via this unique channel, the heavy lepton can be searched for up to a mass of 200 GeV at the Tevatron with 8 fb^-1, and up to 450 (700) GeV at the LHC of 14 TeV C.M.energy with 10 (100) fb^-1. The signal rate at the 10 TeV LHC is reduced to 60-35% for a mass of 200-700 GeV. We also comment on how to distinguish this theory from other models with similar heavy leptons. Finally, we compare the production rates and angular distributions of heavy leptons in e+e- collisions for various models.

description: A left-right symmetric model is discussed with new mirror fermions and a Higgs sector with two doublets and neutral scalar singlets. The seesaw mechanism is generalized, including not only neutrino masses but also charged fermion masses. The spectrum of heavy neutrinos presents a second seesaw mass matrix and has neutrinos masses naturally in the TeV region. The model has very clear signatures for the new neutral vector gauge bosons. Two classes of models are discussed. New mirror neutrinos can be very light and a new $Z^{\prime}$ can be discriminated from other models by a very high invisible branching fraction. The other possibility is that mirror neutrinos can have masses naturally in the TeV region and can be produced through $Z^{\prime}$ decays into heavy neutrino pairs. Signatures and production processes for the model at the LHC energy are also presented.

description: We analyze the breaking of the Wandzura-Wilczek relation for the g_2 structure function, emphasizing its connection with transverse momentum dependent parton distribution functions. We find that the relation is broken by two distinct twist-3 terms, and clarify how these can be separated in measurements of double-spin asymmetries in semi-inclusive deep inelastic scattering. Through a quantitative analysis of available g_2 data we also show that the breaking of the Wandzura-Wilczek relation can be as large as 15-30% of the size of g_2.

Transitional dynamics of the solar convection zone

description: Solar activity is studied using a cluster analysis of the time-fluctuations of sunspot number. In the historic period (1850-1932) the cluster exponent was approximately equal to 0.37 (strong clustering) for the high activity components of the solar cycles. In the modern period (last seven solar cycles: 1933-2007) the cluster exponent was approximately equal to 0.50 (random, white noise-like). Comparing these results with the corresponding data from laboratory experiments on convection it is shown, that in the historic period emergence of sunspots in the solar photosphere was dominated by turbulent photospheric convection. In the modern period, this domination was broken by a new more active dynamics of the inner layers of the convection zone. Cluster properties of the solar wind magnetic field and the aa-geomagnetic-index also support this result. Long-range chaotic dynamics in the solar activity is briefly discussed.

description: Nested words, a model for recursive programs proposed by Alur and Madhusudan, have recently gained much interest. In this paper we introduce quantitative extensions and study nested word series which assign to nested words elements of a semiring. We show that regular nested word series coincide with series definable in weighted logics as introduced by Droste and Gastin. For this we establish a connection between nested words and the free bisemigroup. Applying our result, we obtain characterizations of algebraic formal power series in terms of weighted logics. This generalizes results of Lautemann, Schwentick and Therien on context-free languages.

description: Investigators excavated 652 shovel tests and over 334 m2 at Site 38DR245. The investigations have resulted in the identification of five cultural features and approximately 14,000 artifacts. In addition, archaeologists generated three radiocarbon dates from this site. Data recovery at Site 38DR245 has generated important information related to the Deptford culture in South Carolina. All of these data provide a rare look at the Late Woodland period in a region that lies between the Deptford sites typical of lower coastal plain and the interior riverine sites of South Carolina.

description: A real-time recording setup combining exhaled breath VOC measurements by proton transfer reaction mass spectrometry (PTR-MS) with hemodynamic and respiratory data is presented. Continuous automatic sampling of exhaled breath is implemented on the basis of measured respiratory flow: a flow-controlled shutter mechanism guarantees that only end-tidal exhalation segments are drawn into the mass spectrometer for analysis. Exhaled breath concentration profiles of two prototypic compounds, isoprene and acetone, during several exercise regimes were acquired, reaffirming and complementing earlier experimental findings regarding the dynamic response of these compounds reported by Senthilmohan et al. [1] and Karl et al. [2]. While isoprene tends to react very sensitively to changes in pulmonary ventilation and perfusion due to its lipophilic behavior and low Henry constant, hydrophilic acetone shows a rather stable behavior. Characteristic (median) values for breath isoprene concentration and molar flow, i.e., the amount of isoprene exhaled per minute are 100 ppb and 29 nmol/min, respectively, with some intra-individual day-to-day variation. At the onset of exercise breath isoprene concentration increases drastically, usually by a factor of ~3-4 within about one minute. Due to a simultaneous increase in ventilation, the associated rise in molar flow is even more pronounced, leading to a ratio between peak molar flow and molar flow at rest of ~11. Our setup holds great potential in capturing continuous dynamics of non-polar, low-soluble VOCs over a wide measurement range with simultaneous appraisal of decisive physiological factors affecting exhalation kinetics.
