description: Investors commonly exhibit the disposition effect - the irrational tendency to sell their winning investments and hold onto their losing ones. While this phenomenon has been observed in many traditional markets, it remains unclear whether it also applies to atypical markets like cryptoassets. This paper investigates the prevalence of the disposition effect in Bitcoin using transactions targeting cryptoasset exchanges as proxies for selling transactions. Our findings suggest that investors in Bitcoin were indeed subject to the disposition effect, with varying intensity. They also show that the disposition effect was not consistently present throughout the observation period. Its prevalence was more evident from the boom and bust year 2017 onwards, as confirmed by various technical indicators. Our study suggests irrational investor behavior is also present in atypical markets like Bitcoin.

description: Recent efforts of the Research Data Alliance have established a conceptual model for the management of research data that promotes the use of digital objects, transcending the traditional notion of files and decoupling questions of access and use from location and storage. In this context, the need for building aggregations or collections of such objects has become an essential element. However, contemporary work on object collections focuses on primarily describing such collections through metadata, whereas research data management practice requires not only to describe collections, but to make them actionable by automated processes to be able to cope with ever increasing amounts and volumes of data. To this effect, this recommendation provides a comprehensive model for actionable collections and a technical interface specification to enable client-server interaction. It also reports on first adoption and implementation efforts across communities and institutions and provides perspectives on the use of data types in connection with collection structures, highlighting pathways for possible future work.

description: Non-Intrusive Load Monitoring (NILM) aims to predict the status or consumption of domestic appliances in a household only by knowing the aggregated power load. NILM can be formulated as regression problem or most often as a classification problem. Most datasets gathered by smart meters allow to define naturally a regression problem, but the corresponding classification problem is a derived one, since it requires a conversion from the power signal to the status of each device by a thresholding method. We treat three different thresholding methods to perform this task, discussing their differences on various devices from the UK-DALE dataset. We analyze the performance of deep learning state-of-the-art architectures on both the regression and classification problems, introducing criteria to select the most convenient thresholding method.

description: This thesis describes the use of platform-derived chemicals as novel, bio-based intermediates to the synthesis of value-added compounds. Levulinic acid-derived angelica lactones were used to preapre C3 chemicals such as malonic acid via ozonolysis and novel poly-norbornene-like polymers. Glycolaldehyde, obtained from lignocellulose, was employed for the first time as C1 building block for the N-formylation of secondary amines by catalyst-free radical oxidation. Methyl vinyl glycolate, a side stream product of the production of lactate from sugars, was used as precursor for bio-based polyester.

description: We study dark solitons near potential and nonlinearity steps and combinations thereof, forming rectangular barriers. This setting is relevant to the contexts of atomic Bose-Einstein condensates (where such steps can be realized by using proper external fields) and nonlinear optics (for beam propagation near interfaces separating optical media of different refractive indices). We use perturbation theory to develop an equivalent particle theory, describing the matter-wave or optical soliton dynamics as the motion of a particle in an effective potential. This Newtonian dynamical problem provides information for the soliton statics and dynamics, including scenarios of reflection, transmission, or quasi-trapping at such steps. The case of multiple such steps and its connection to barrier potentials is also touched upon. Our analytical predictions are found to be in very good agreement with the corresponding numerical results.

Comparing Panoramic Radiographs and CBCT: Impact on Radiographic Features and Differential Diagnoses
Creators: name: Lim, Li Zhen

Year: 2017

description: Cone beam computed tomography (CBCT) is known to have many advantages over panoramic radiography (PAN). However, few studies quantitatively demonstrate the benefits of CBCT for imaging intraosseous pathology. The aims of this study were to determine whether lesion features appear differently on PAN and CBCT, and the clinical impact of CBCT vs PAN. Three oral radiologists reviewed 33 sets of PANs and CBCTs of biopsy-proven lesions, described lesion features and provided up to three ranked differential diagnoses and their confidence levels associated with each diagnosis. Confidence levels were weighted by the rank at which the correct diagnosis was provided. Differences were present between PAN and CBCT with respect to lesion border definition, continuity of corticated borders, effect on neurovascular canals, expansion, cortical thinning and destruction. There was no association between the two modalities and the rank at which the correct differential diagnoses was made, or with the observers’ weighted confidence levels.

description: The impact of salinity on coastal peatland vegetation was investigated. Phragmites australis is the most dominant emergent macrophyte in freshwater to mesohaline peatlands. Other common species include Typha latifolia, Carex spp. and Schoenoplectus tabernaemontani. P. australis and S. tabernaemontani are resilient to salinity and frequent salinity pulses while Carex sp. and T. latifolia are not. Litter decomposition rates of these macrophytes do not vary in freshwater and oligohaline peatlands.

description: Low surface brightness (LSB) galaxies form a major class of galaxies, and are characterized by low disc surface density and low star formation rate. These are known to be dominated by dark matter halo from the innermost regions. Here we study the role of dark matter halo on the grand-design, $m=2$, spiral modes in a galactic disc by carrying out a global mode analysis in the WKB approximation. The Bohr-Sommerfeld quantization rule is used to determine how many discrete global spiral modes are permitted. First a typical superthin LSB galaxy, UGC 7321 is studied by taking only the galactic disc, modelled as fluid; and then the disc embedded in a dark matter halo. We find that both cases permit the existence of global spiral modes. This is in contrast to earlier results where the inclusion of dark matter halo was shown to nearly fully suppress local, swing-amplified spiral features. Although technically global modes are permitted in the fluid model as shown here, we argue that due to lack of tidal interactions, these are not triggered in LSB galaxies. For comparison, we carried out a similar analysis for the Galaxy, for which the dark matter halo does not dominate in the inner regions. We show that here too the dark matter halo has little effect, hence the disc embedded in a halo is also able to support global modes. The derived pattern speed of the global mode agrees fairly well with the observed value for the Galaxy.

description: DEtection TRansformer (DETR) for object detection reaches competitive performance compared with Faster R-CNN via a transformer encoder-decoder architecture. However, trained with scratch transformers, DETR needs large-scale training data and an extreme long training schedule even on COCO dataset. Inspired by the great success of pre-training transformers in natural language processing, we propose a novel pretext task named random query patch detection in Unsupervised Pre-training DETR (UP-DETR). Specifically, we randomly crop patches from the given image and then feed them as queries to the decoder. The model is pre-trained to detect these query patches from the input image. During the pre-training, we address two critical issues: multi-task learning and multi-query localization. (1) To trade off classification and localization preferences in the pretext task, we find that freezing the CNN backbone is the prerequisite for the success of pre-training transformers. (2) To perform multi-query localization, we develop UP-DETR with multi-query patch detection with attention mask. Besides, UP-DETR also provides a unified perspective for fine-tuning object detection and one-shot detection tasks. In our experiments, UP-DETR significantly boosts the performance of DETR with faster convergence and higher average precision on object detection, one-shot detection and panoptic segmentation.

Climatosceptique

description: Il existe un phénomène dans la pensée contemporaine qui s'appelle le changement climatique. Cependant, lorsque nous observons les sondages d'opinion, nous remarquons qu'il existe un grand écart entre les croyances sur le changement climatique de la communauté scientifique et le reste de la population. Ceci a mené une réflexion sur la manière dont le groupe responsable de la découverte et la transmission d'informations sur le climat peut être cru ou douté par le reste de la population et, de façon plus générale, le rôle de la science dans la résolution de controverses. Dans cette même intention, nous nous sommes servis de la sociologie pragmatique de la justification pour réconcilier les explications précédentes pour cet écart de même que la théorie du risque. Une exploration statistique a alors été employée pour tenter de comprendre la définition du risque qui soutenait la création d'organismes climatosceptiques américains. Nous avons fait ceci en construisant des modèles en nous servant de la régression logistique pour étudier la relation entre la croyance au consensus scientifique sur le changement climatique et quatre différentes facettes du phénomène en soi, contrôlés par des variables démographiques, religieux, de classe sociale, politiques et scientifiques. Nous avons pu ainsi déterminer quelles variables impactent la relation entre l'autorité scientifique et un phénomène en soi. Une étude de nos modèles nous a amenés à conclure que les catégories démographiques les plus privilégiées ainsi qu'une certaine classe sociale semi-spécialisée se servant davantage des techniques de production associés à la première modernité sont les plus propices à douter le changement climatique, indépendamment du consensus scientifique. Une recherche sociologie subséquente sur les organismes climatosceptiques doit donc être structurée autour de ces deux facteurs.

description: Graphene samples can have a very high carrier mobility if influences from the substrate and the environment are minimized. Embedding a graphene sheet into a heterostructure with hexagonal boron nitride (hBN) on both sides was shown to be a particularly efficient way of achieving a high bulk mobility. Nanopatterning graphene can add extra damage and drastically reduce sample mobility by edge disorder. Preparing etched graphene nanostructures on top of an hBN substrate instead of SiO2 is no remedy, as transport characteristics are still dominated by edge roughness. Here we show that etching fully encapsulated graphene on the nanoscale is more gentle and the high mobility can be preserved. To this end, we prepared graphene antidot lattices where we observe magnetotransport features stemming from ballistic transport. Due to the short lattice period in our samples we can also explore the boundary between the classical and the quantum transport regime.

description: The security of finite-length keys is essential for the implementation of device-independent quantum key distribution (DIQKD). Presently, there are several finite-size DIQKD security proofs, but they are mostly focused on standard DIQKD protocols and do not directly apply to the recent improved DIQKD protocols based on noisy preprocessing, random key measurements, and modified CHSH inequalities. Here, we provide a general finite-size security proof that can simultaneously encompass these approaches, using tighter finite-size bounds than previous analyses. In doing so, we develop a method to compute tight lower bounds on the asymptotic keyrate for any such DIQKD protocol with binary inputs and outputs. With this, we show that positive asymptotic keyrates are achievable up to depolarizing noise values of $9.33\%$, exceeding all previously known noise thresholds. We also develop a modification to random-key-measurement protocols, using a pre-shared seed followed by a "seed recovery" step, which yields substantially higher net key generation rates by essentially removing the sifting factor. Some of our results may also improve the keyrates of device-independent randomness expansion.

Symmetry constraints on superconductivity in twisted bilayer graphene: Fractional vortices, $4e$ condensates or non-unitary pairing

description: When two graphene sheets are twisted relative to each other by a small angle, enhanced correlations lead to superconductivity whose origin remains under debate. Here, we derive some general constraints on superconductivity in twisted bilayer graphene (TBG), independent of its underlying mechanism. Neglecting weak coupling between valleys, the global symmetry group of TBG consists of independent spin rotations in each valley in addition to valley charge rotations, $ {\rm SU}(2) \times {\rm SU}(2) \times {\rm U}_V(1) $. This symmetry is further enhanced to a full ${\rm SU}(4)$ in the idealized chiral limit. In both cases, we show that any charge $2e$ pairing must break the global symmetry. Additionally, if the pairing is unitary the resulting superconductor admits fractional vortices. This leads to the following general statement: Any superconducting condensate in either symmetry class has to satisfy one of three possibilities: (i) the superconducting pairing is non-unitary, (ii) the superconducting condensate has charge $2e$ but admits at least half quantum vortices which carry a flux of $h/4e$, or (iii) the superconducting condensate has charge $2me$, $m>1$, with vortices carrying $h/2me$ flux. The latter possibility can be realized by a symmetric charge $4e$ superconductor ($m=2$). Non-unitary pairing (i) is expected in TBG for superconductors observed in the vicinity of flavor polarized states. On the other hand, in the absence of flavor polarization, e.g. in the vicinity of charge neutrality, one of the two exotic possibilities (ii) and (iii) is expected. We sketch how all three scenarios can be realized in different limits within a strong coupling theory of superconductivity based on skyrmions. Finally we discuss the effect of symmetry lowering anisotropies and experimental implications of these scenarios.

description: The framework of spherical transforms and Pólya ensembles is of utility in deriving structured analytic results for sums and products of random matrices in a unified way. In the present work, we will carry over this framework to study products of unitary matrices. Those are not distributed via the Haar measure, but still are drawn from distributions where the eigenvalue and eigenvector statistics factorise. They include the circular Jacobi ensemble, known in relation to the Fisher-Hartwig singularity in the theory of Toeplitz determinants, as well as the heat kernel for Brownian motion on the unitary group. We define cyclic Pólya frequency functions and show their relation to the cyclic Pólya ensembles, give a uniqueness statement for the corresponding weights, and derive the determinantal point processes of the eigenvalue statistics at fixed matrix dimension. An outline is given of problems one may encounter when investigating the local spectral statistics.

description: High-energy synchrotron X-ray diffraction was utilized to study the mechanical response of the f.c.c $δ$-hydride phase, the intermetallic precipitation with hexagonal C14 lave phase and the $α$-Zr phase in the Zircaloy-4 materials with a hydride rim/blister structure near one surface of the material during in-situ uniaxial tension experiment at 200 \si{\degreeCelsius}. The f.c.c $δ$ was the only hydride phase observed in the rim/blister structure. The conventional Rietveld refinement was applied to measure the macro-strain equivalent response of the three phases. Two regions were delineated in the applied load versus lattice strain measurement: a linear elastic strain region and region that exhibited load partitioning. Load partitioning was quantified by von Mises analysis. The three phases were observed to have similar elastic modulus at 200 \si{\degreeCelsius}.

description: We present mathematical models, computational algorithms and software, which can be used for prediction of results of prosthetic treatment. More interest issue is biomechanics of the periodontal complex because any prosthesis is accompanied by a risk of overloading the supporting elements. Such risk can be avoided by the proper load distribution and prediction of stresses that occur during the use of dentures. We developed the mathematical model of the periodontal complex and its software implementation. This model is based on linear elasticity theory and allows to calculate the stress and strain fields in periodontal ligament and jawbone. The input parameters for the developed model can be divided into two groups. The first group of parameters describes the mechanical properties of periodontal ligament, teeth and jawbone (for example, elasticity of periodontal ligament etc.). The second group characterized the geometric properties of objects: the size of the teeth, their spatial coordinates, the size of periodontal ligament etc. The mechanical properties are the same for almost all, but the input of geometrical data is complicated because of their individual characteristics. In this connection, we develop algorithms and software for processing of images obtained by computed tomography (CT) scanner and for constructing individual digital model of the tooth-periodontal ligament-jawbone system of the patient. Integration of models and algorithms described allows to carry out biomechanical analysis on three-dimensional digital model and to select prosthesis design.

description: We propose injective generative models called Trumpets that generalize invertible normalizing flows. The proposed generators progressively increase dimension from a low-dimensional latent space. We demonstrate that Trumpets can be trained orders of magnitudes faster than standard flows while yielding samples of comparable or better quality. They retain many of the advantages of the standard flows such as training based on maximum likelihood and a fast, exact inverse of the generator. Since Trumpets are injective and have fast inverses, they can be effectively used for downstream Bayesian inference. To wit, we use Trumpet priors for maximum a posteriori estimation in the context of image reconstruction from compressive measurements, outperforming competitive baselines in terms of reconstruction quality and speed. We then propose an efficient method for posterior characterization and uncertainty quantification with Trumpets by taking advantage of the low-dimensional latent space.

Between Symbolism and Realism: The Use of Symbolic and Non-Symbolic Language in Ancient Jewish Apocalypses 333-63 BCE
Creators: name: Reynolds, Bennie H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: This dissertation is a systematic analysis of the language of ancient Jewish historical apocalypses. I investigate how the dramatis personae, i.e., deities, angels/demons, and humans (both individuals and groups) are described in the Book of Daniel (2, 7, 8, 10-12) the Animal Apocalypse (1 Enoch 85-90), 4QFourKingdomsa-b ar, the Book of the Words of Noah (1QapGen 5 29-18 ?), the Apocryphon of Jeremiah C, and 4QPseudo-Daniela-b ar. The primary methodologies for this study are linguistic- and motif-historical analysis and the theoretical framework is informed by a wide range of ancient and modern thinkers including Artemidorus of Daldis, Ferdinand de Saussure, Charles Peirce, Leo Oppenheim, Claude Lévi-Strauss, and Umberto Eco. The most basic contention of this study is that the data now available from the Dead Sea Scrolls significantly alter how one should conceive of the genre apocalypse in the Hellenistic Period. This basic contention is borne out by five primary conclusions. First, while some apocalypses employ symbolic language to describe the actors in their historical reviews, others use non-symbolic language. Some texts, especially from the Book of Daniel, are mixed cases. Second, among the apocalypses that use symbolic language, a limited and stable repertoire of symbols obtain across the genre and bear witness to a series of conventional associations. Third, in light of the conventional associations present in symbolic language as well as the specific descriptions of particular historical actors, it appears that symbolic language is not used to hide or obscure its referents, but to provide the reader with embedded interpretative tools. Fourth, while several apocalypses do not use symbolic ciphers to encode their historical actors, they often use cryptic language that may have functioned as a group-specific language. Fifth, the language of apocalypses appears to indicate that these texts were not the domain of only one social group or even one type of social group. Some texts presume large audiences and others presume more limited ones. In other words, apocalypticism was not the exclusive domain of a small fringe group even if several small fringe groups appear to have internalized the ideology associated with the genre apocalypse.

description: Propelling microorganisms through fluids and moving fluids along cellular surfaces are essential biological functions accomplished by long, thin structures called motile cilia and flagella, whose regular, oscillatory beating breaks the time-reversal symmetry required for transport. Although top-down experimental approaches and theoretical models have allowed us to broadly characterize such organelles and propose mechanisms underlying their complex dynamics, constructing minimal systems capable of mimicking ciliary beating and identifying the role of each component remains a challenge. Here we report the bottom-up assembly of a minimal synthetic axoneme, which we call a synthoneme, using biological building blocks from natural organisms, namely pairs of microtubules and cooperatively associated axonemal dynein motors. We show that upon provision of energy by ATP, microtubules undergo rhythmic bending by cyclic association-dissociation of dyneins. Our simple and unique beating minimal synthoneme represents a self-organized nanoscale biomolecular machine that can also help understand the mechanisms underlying ciliary beating.

description: Genome sizes have evolved to vary widely, from 250 bases in viroids to 670 billion bases in amoeba. This remarkable variation in genome size is the outcome of complex interactions between various evolutionary factors such as point mutation rate, population size, insertions and deletions, and genome editing mechanisms that may be specific to certain taxonomic lineages. While comparative genomics analyses have uncovered some of the relationships between these diverse evolutionary factors, we still do not understand what drives genome size evolution. Specifically, it is not clear how primordial mutational processes of base substitutions, insertions, and deletions influence genome size evolution in asexual organisms. Here, we use digital evolution to investigate genome size evolution by tracking genome edits and their fitness effects in real time. In agreement with empirical data, we find that mutation rate is inversely correlated with genome size in asexual populations. We show that at low point mutation rate, insertions are significantly more beneficial than deletions, driving genome expansion and acquisition of phenotypic complexity. Conversely, high mutational load experienced at high mutation rates inhibits genome growth, forcing the genomes to compress genetic information. Our analyses suggest that the inverse relationship between mutation rate and genome size is a result of the tradeoff between evolving phenotypic innovation and limiting the mutational load.

description: Die Darm-Gelenk-Achse ist Grundlage dieser experimentellen Arbeit, in der der Einfluss einer Clostridioides difficile-Infektion auf eine Arthritis untersucht wurde. Als experimenteller Organismus diente die DBA/1J × B10.Q F1-Maus, die mit einem von drei verschiedenen C. difficile-Stämmen infiziert wurden. Anschließend wurde die arthritischen Beschwerden ausgelöst. In der Folge führte eine spontane Ausheilung der Infektion zu einer reduzierten Inzidenz der nachfolgenden Kollagen-induzierten Arthritis und ging mit einer veränderten T-Zell-Polarisation einher.
