description: Bacteria can adjust the structure of colonies and biofilms to enhance their survival rate under external stress. Here, we explore the link between bacterial interaction forces and colony structure. We show that the activity of extracellular pilus motors enhances local ordering and accelerates fusion dynamics of bacterial colonies. The radial distribution function of mature colonies shows local fluid-like order. The degree and dynamics of ordering are dependent on motor activity. At a larger scale, the fusion dynamics of two colonies shows liquid-like behavior whereby motor activity strongly affects tension and viscosity.

description: The synthesis of palladium complexes derived from 4-amino-3-pentadecyl-3H-1,2,4-triazole-3-thiones and 3-pentadecyl-1,3,4-oxadiazole-2(3H)-thiones are reported. They were obtained from palladium acetate and dipotassium tetrachloropalladate(II) and their composition was assigned by elemental analysis (solid state). The resulting metallic entities were also characterized in solution based in mass spectrometry experiments. Their application in organic synthesis as cross-coupling reaction catalysts is described. One example of both conventional Tsuji-Trost and Mizoroki-Heck reactions were efficiently carried out in very high chemical yield.
Negative Energy Densities and the Limit of Classical Space-Time

description: Although negative energy densities are predicted by relativistic quantum field theories, I present an argument that an "operational" positivity still holds: the energy in a region, plus the energy of an isolated device which traps or measures that energy, must be positive. If we assume Einstein's field equation, this means the local geometry of a negative energy-density region cannot be measured by the trajectories of test particles. So far, all attempts to design thought-experiments to verify a classical local geometry in the negative energy-density region have failed. It seems we must impute a quantum character to such a space-time regime.

description: In Aharonov-Bohm (AB) cavities forming doubly connected ballistic structures, h/e AB oscillations that result from the interference among the complicated trapped paths in the cavity can be described by the framework of the semiclassical theory. We derive formulas of the correlation function C(Δϕ) of the nonaveraged magnetoconductance for chaotic and regular AB cavities. The different higher harmonics behaviors for C(Δϕ) are related to the differing distribution of classical dwelling times. The AB oscillation in ballistic regimes provides an experimental probe of quantum signatures of classical chaotic and regular dynamics.

Homogenizing the Masses: American Republican Ideology and the Threat of "intemperate democracy" in Robert Munford's The Patriots (c. 1777)
Creators: name: Detsi-Diamanti, Zoe
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2010

description: The creation of the American nation and the spread of American nation­alism relied heavily upon a homogenizing social philosophy that extolled liberty and equality and united all citizens in the promotion and demon­stration of public and private virtue. However, despite the much-adver­tised "self-evident" truths, early American society was tormented by fears of internal dissension and the cultural disruption of an "unqualified" mass of non-Americans. This paper examines how the concepts of the "individ­ual" and the "mass" were implicated in the ideological mechanisms of the political ideology of republicanism which tended to smooth over the nu­ances and complexities of a hardly acknowledged ethnically and culturally heterogeneous society. By focusing on Robert Munford's post-revolution­ary satire The Patriots (c. 1777) as the only dramatic attempt of the time that exposed the limits and contradictions of the republican experiment, this paper will probe into the ideological illusionism of republicanism and explore the reality of the nativist exclusiveness of American society and the rigid boundaries of the American political identity.

description: In the turbulent 1830s, the young priest Prosper Gueranger determines to restore France's dispersed Benedictine community. Gueranger revitalizes a religious community, as well as a thousand years of monastic tradition. He does this work with full knowledge that he will be criticized, in the ethos of postrevolutionary France, for sacrificing the individual to the col­lective. In the decadent 1890s, Joris-Karl Huysmans writes En route, a novel that continues the narrative of the novelist's alter-ego Durtal. Durtal, dis­gusted with life in Paris, leaves on retreat to a Trappist monastery, where his soul is "surprised by grace" in the atmosphere of "mystical literature, liturgy and plainchant" (Huysmans qtd. in Baldick 288). Durtal undertakes his own individual 'rebuilding' within the monastic community. My article focuses on the conversion narrative in a century dedicated to the reinforcement of individualism both personal and regional. These au­thors represent a cultural continuum in the nineteenth century, one that sublimates the personal to the collective, yet with the seemingly paradox­ical objective of raising up the individual. The figures I study here repre­sent different modes of religious activity or adherence; each approaches religious discourse in ways that investigate the place of the individual within the infrastructure of a plural organism.

description: Die Fallstudie untersuchte Gestaltungsprozesse in virtuellen Umgebungen. Trotz der immer breiteren Verfügbarkeit von Virtual Reality durch fortschreitende technologische Entwicklungen und thematische Anknüpfungspunkte zum Bildnerischen Gestalten sind Gestaltungsprozesse und deren Charakteristika in virtuellen Umgebungen noch wenig erforscht. Es wurde der Frage nachgegangen, wie sich Handlungen während Gestaltungsprozessen in den virtuellen Umgebungen der Virtual-Reality-Anwendungen Tilt Brush und SculptrVR aus der Aussen- und Innenperspektive zeigen. Der Fokus lag auf der Frage, wodurch sich solche Gestaltungsprozesse auszeichnen und welche Momente der Irritation sich während des Gestaltungsprozesses in der virtuellen Umgebung zeigen. In Form einer qualitativen Fallstudie wurden Gestaltungsprozesse zweier Teilnehmenden in virtuellen Umgebungen näher betrachtet. Dafür wurden zwei Studierende im Rahmen ihrer Ausbildung zur Primarlehrperson begleitet. Mithilfe von Videografie wurden die Gestaltungsprozesse in den virtuellen Umgebungen von Tilt Brush und SculptrVR aus der Aussen- und Innenperspektive beobachtet. Das Material wurde mit der Videointeraktionsanalyse in Datensitzungen ausgewertet. Aus den Ergebnissen geht unter anderem hervor, dass Dreidimensionalität und die Möglichkeit der Betrachtung aus 360°muss im Gestaltungsprozess einen Zweck erfüllen, damit dies in der VR-Anwendung ausgeschöpft wird. Typische Funktionen, Eigenheiten und Werkzeuge der VR-Anwendungen wie der Smoothing Brush (dt. Glättungswerkzeug) oder der Eraser (Radiergummi als Löschwerkzeug) im Gestaltungsprozess einerseits Irritationen hervorrufen, aber auch das Experimentieren fördern und grundlegenden Veränderungen des Gestaltungsprozesses anregen.

The Equation of State of Neutron-Rich Matter at Fourth Order of Chiral Effective Field Theory and the Radius of a Medium-Mass Neutron Star

Year: 2022

subject: FOS: Physical sciences

description: We report neutron star predictions based on our most recent equations of state. These are derived from chiral effective field theory, which allows for a systematic development of nuclear forces, order by order. We utilize high-quality two-nucleon interactions and include all three-nucleon forces up to fourth order in the chiral expansion. Our ab initio predictions are restricted to the domain of applicability of chiral effective field theory. However, stellar matter in the interior of neutron stars can be up to several times denser than normal nuclear matter at saturation, and its composition is essentially unknown. Following established practices, we extend our microscopic predictions to higher densities matching piecewise polytropes. The radius of the average-size neutron star, about 1.4 solar masses, is sensitive to the pressure at normal densities, and thus it is suitable to constrain ab initio theories of the equation of state. For this reason, we focus on the radius of medium-mass stars. We compare our results with other theoretical predictions and recent constraints.

description: This paper explores how business reconciles the perceived conflicting demands of social and profit logic to deliver value to shareholders and the wider community it serves. Through a human-centered design lens, the paper identifies co-creation as pivotal in the design of the business model that delivers social and economic value. Empirical data from an aquaculture SME case study was collected and analyzed to comprehend the role of social good in the development of the business model. The results demonstrate that societal improvements can be achieved when concurrently considered and designed into each stage of the business model development. The findings reveal that technology when deployed within the context of economic and societal improvements has the potential to support businesses in organizing services that deliver economic, societal, and environmental benefits. Replicating this approach requires organizations to develop a deep understanding of the social context that their customers operate within.
Double-Decker Filament Configuration Revealed by Mass Motions

description: It is often envisaged that dense filament material lies in the dips of magnetic field lines belonging to either a sheared arcade or a magnetic flux rope. But it is also debated which configuration correctly depicts filaments' magnetic structure, due to our incapacity to measure the coronal magnetic field. In this paper, we address this issue by employing mass motions in an active-region filament to diagnose its magnetic structure. The disturbance in the filament was driven by a surge initiated at the filament's eastern end in the NOAA active region 12685, which was observed by the 1-m New Vacuum Solar Telescope (NVST) in the H$α$ line center and line wing ($\pm0.4$~Å). Filament material predominately exhibits two kinds of motions, namely, rotation about the spine and longitudinal oscillation along the spine. The former is evidenced by antisymmetric Doppler shifts about the spine; the latter features a dynamic barb with mass extending away from the H$α$ spine until the transversal edge of the EUV filament channel. The longitudinal oscillation in the eastern section of the filament is distinct from that in the west, implying that the underlying field lines have different lengths and curvature radii. The composite motions of filament material suggest a double-decker host structure with mixed signs of helicity, comprising a flux rope atop a sheared-arcade system.

Robust Optimization through Neuroevolution
Creators: name: Pagliuca, Paolo

Publisher: name: arXiv
Year: 2018
Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: We propose a method for evolving solutions that are robust with respect to variations of the environmental conditions (i.e. that can operate effectively in new conditions immediately, without the need to adapt to variations). The obtained results show how the method proposed is effective and computational tractable. It permits to improve performance on an extended version of the double-pole balancing problem, to outperform the best available human-designed controllers on a car racing problem, and to generate rather effective solutions for a swarm robotic problem. The comparison of different algorithms indicates that the CMA-ES and xNES methods, that operate by optimizing a distribution of parameters, represent the best options for the evolution of robust neural network controllers.
The key role of antibonding electron transfer in surface chemisorption and heterogeneous catalysis

description: The description of the chemical bond between a solid surface and an atom or a molecule is the fundamental basis for understanding a broad range of scientific problems in heterogeneous catalysis, semiconductor device fabrication, and fuel cells. Widespread understandings are based on the molecular orbital theory and focused on the degree of filling of antibonding surface-adsorbate states that weaken bonding on surfaces. The unoccupied antibonding surface-adsorbate states are often tacitly assumed to be irrelevant. Here, we show that most antibonding states become unoccupied because the electrons that would occupy these antibonding states are transferred to the lower-energy Fermi level. Such antibonding electron transfer goes beyond molecular orbital theory. It leads to an energy gain that largely controls the trends of surface adsorption strength and can serve as a primary descriptor for bonding on surfaces. This finding is illustrated from the first-principles study of hydrogen adsorption on MoS$_2$ surfaces. A clear linear relationship between the energies of antibonding electron transfer and hydrogen adsorption is identified. The hydrogen evolution reaction on MoS$_2$ is found to originate from the in-gap states induced by sulfur vacancies or edges. The effects of surface inhomogeneity (e.g., defects, step edges) on surface catalysis can be understood from the corresponding different energies gained from antibonding electron transfer. The emerging picture also offers a physically different explanation for the well-known $d$-band theory for hydrogen adsorption on transition metal surfaces.

description: A dc current induced in a quantum constriction by a traveling acoustic wave (or by non-equilibrium ballistic phonons) is considered. We show that in many important situations the effect is originated from acoustically-induced scattering between the propagating and reflecting states in the constriction. Two particular regimes corresponding to relatively high and low acoustic frequencies are discussed. In the first regime, the acoustoelectric effect in a smooth constriction can be understood by semi-classical considerations based on local conservation laws. For the low frequency regime, we show that the acousto-conductance is closely related to the zero field conductance. The qualitative considerations are confirmed by numerical calculations both for smooth and abrupt channels.

description: We report the discovery of a circular shell centred on the Be X-ray binary (BeXB) SXP 1323 in the Small Magellanic Cloud (SMC). The shell was detected in an Halpha image obtained with the Very Large Telescope (VLT). Follow-up spectroscopy with the Southern African Large Telescope (SALT) showed that the shell expands with a velocity of $\approx$ 100 km/s and that its emission is due to shock excitation. We suggest that this shell is the remnant of the supernova explosion that led to the formation of the SXP 1323's neutron star $\approx$ 40 000 yr ago. SXP 1323 represents the second known case of a BeXB associated with a supernova remnant (the first one is SXP 1062). Interestingly, both these BeXBs harbour long period pulsars and are located in a low-metallicity galaxy.

description: In the standard minority game, each agent in the minority group receives the same payoff regardless of the size of the minority group. Of great interest for real social and biological systems are cases in which the payoffs to members of the minority group depend on the size of the minority group. This latter includes the fixed sum game. We find, remarkably, that the phase structure and general scaling behavior of the standard minority game persists when the payoff function depends on the size of the minority group. there is still a phase transition at the same value of z, the ratio of the dimension of the strategy space to the number of agents playing the game. We explain the persistence of the phase structure and argue that it is due to the absence of temporal cooperation in the dynamics of the minority game. We also discuss the behavior of average agent wealth and the wealth distribution in these variable payoff games.

This gives added significance to measurements of G and to Cavendish-type experiments.

description: The slave boson mean-field studies of the ground state of the Hubbard model with correlated hopping were performed. The approach qualitatively recovers the exact results for the case of the hopping integral t equal to the correlated hopping integral X. The phase diagram for the strongly correlated state with only singly occupied sites, the weakly correlated state, where single and double occupation is allowed, and for the superconducting state, was determined for any values of X and any electron concentration n. At the half-filled band (n=1) a direct transition from the superconductor to the Mott insulator was found. In the region of strong correlations the superconducting solution is stable for n close to 1, in contrast to the case of weak correlations, in which superconductivity occurs at n close to 0 and n close to 2. We found also that strong correlations change characteristics of the superconducting phase, e.g. the gap in the excitation spectrum has a nonexponential dependence close to the point of the phase transition.

description: We present the first spectroscopic survey of intrinsically low Lx clusters at z>>0, with HST WFPC2 imaging and ground-based spectroscopy. We study 172 confirmed cluster members in a sample of ten clusters at z=0.23-0.3, with Lx<4.E43 h^{-2} ergs/s. The core of each cluster is imaged with WFPC2 in the F702W filter, and the spectroscopic sample is statistically complete to Mr-19.0+5log(h), within an 11' field. The clusters are dynamically well-separated from the surrounding field and the velocity dispersions range from ~350-850 km/s. Emission line galaxies in these clusters are relatively rare, comprising only 22 +/- 4% of the sample. There is no evidence that these emission-line galaxies are dynamically distinct from the majority of the cluster population, though our sample is too small to rule out the ~30% difference that has been observed in more massive clusters. We find eleven galaxies, comprising 6% of the cluster members, which are disk-dominated but show no sign of emission in their spectrum. Most of these are relatively isolated, spiral galaxies with smooth disks. We find no cluster members with a starburst or post-starburst spectrum. The striking similarity between the spectral and morphological properties of galaxies in these clusters and those of galaxies in more massive systems at similar redshifts implies that the physical processes responsible for truncating star formation in galaxies are not restricted to the rare, rich cluster environment, but are viable in much more common environments. In particular, we conclude that ram pressure stripping or cluster-induced starbursts cannot be solely responsible for the low star formation rates in these systems.

description: The change of a material's electrical resistance (R) in response to an external magnetic field (B) provides subtle information for the characterization of its electronic properties and has found applications in sensor and storage related technologies. In good metals, Boltzmann's theory predicts a quadratic growth in magnetoresistance (MR) at low B, and saturation at high fields. On the other hand, a number of nonmagnetic materials with weak electronic correlation and low carrier concentration for metallicity, such as inhomogeneous conductors, semimetals, narrow gap semiconductors and topological insulators, two-dimensional electron gas (2DEG) show positive, non-saturating linear magnetoresistance (LMR). However, observation of LMR in single crystals of a good metal is rare. Here we present low-temperature, angle dependent magnetotransport in single crystals of the antiferromagnetic metal, TmB4. We observe large, positive and anisotropic MR(B), which can be tuned from quadratic to linear by changing the direction of the applied field. In view of the fact that isotropic, single crystalline metals with large Fermi surface (FS) are not expected to exhibit LMR, we attribute our observations to the anisotropic FS topology of TmB4. Furthermore, the linear MR is found to be temperature-independent, suggestive of quantum mechanical origin.

description: Bayesian parameter estimation is fast becoming the language of gravitational-wave astronomy. It is the method by which gravitational-wave data is used to infer the sources' astrophysical properties. We introduce a user-friendly Bayesian inference library for gravitational-wave astronomy, Bilby. This python code provides expert-level parameter estimation infrastructure with straightforward syntax and tools that facilitate use by beginners. It allows users to perform accurate and reliable gravitational-wave parameter estimation on both real, freely-available data from LIGO/Virgo, and simulated data. We provide a suite of examples for the analysis of compact binary mergers and other types of signal model including supernovae and the remnants of binary neutron star mergers. These examples illustrate how to change the signal model, how to implement new likelihood functions, and how to add new detectors. Bilby has additional functionality to do population studies using hierarchical Bayesian modelling. We provide an example in which we infer the shape of the black hole mass distribution from an ensemble of observations of binary black hole mergers.

description: Οι ανανεώσιμες πηγές ενέργειας είναι πλέον απαραίτητες στη ζωή μας. Τα συμβατικά καύσιμα πρέπει να αντικατασταθούν στο μεγαλύτερο μέρος τους, αν όχι εξολοκλήρου, από τις ανανεώσιμες πηγές ενέργειας καθώς η ανάγκη μείωσης της περιβαλλοντικής ρύπανσης είναι πλέον επιτακτική. Η εκμετάλλευση των ανανεώσιμων πηγών ενέργειας όπως ο ήλιος και ο αέρας προσφέρουν πολλά οφέλη τόσο περιβαλλοντικά όσο και οικονομικά. Η παρούσα διπλωματική εργασία αξιολογεί, οικονομικά και τεχνικά, μια επένδυση σε μονάδα παραγωγής βιοαερίου ισχύος 499 kW. Στόχος της συγκεκριμένης επένδυσης είναι η παραγωγή και η πώληση ηλεκτρικής ενέργειας από την καύση βιοαερίου το οποίο θα παραχθεί μέσω της διαδικασίας της αναερόβιας χώνευσης (Α.Χ.) και χρησιμοποιώντας ως πρώτη ύλη αγροκτηνοτροφικά απόβλητα. Αρχικά, γίνεται μια εισαγωγή σχετικά με τις ανανεώσιμες πηγές ενέργειας και τη σημαντικότητά τους, καθώς και τα επίπεδα χρήσης τους σε διάφορα χρονικά διαστήματα. Επιπλέον, γίνεται περιγραφή της διαδικασίας της αναερόβιας χώνευσης, της παραγωγής βιοαερίου, του όρου της βιομάζας αλλά και των εγκαταστάσεων από τις οποίες αποτελείται μια μονάδα παραγωγής βιοαερίου. Ακολουθεί ανάλυση σκοπιμότητας με το μείγμα της πρώτης ύλης να αποτελείται από αγροτοκτηνοτροφικά απόβλητα. Η αξιολόγηση της επένδυσης έγινε με τη χρήση των εξής δεικτών: Καθαρής Παρούσας Αξίας (ΚΠΑ), του Εσωτερικού Επιτοκίου Απόδοσης (ΙRR), του χρόνου επανείσπραξης του αρχικού κεφαλαίου και των δεικτών καθαρού περιθωρίου κέρδους και απόδοσης ιδίων κεφαλαίων. Το εξεταζόμενο επενδυτικό έργο είναι ελκυστικό και κερδοφόρο.

description: We present numerical exact results for the polaronic band structure of the Holstein molecular crystal model in one and two dimensions. The use of direct Lanczos diagonalization technique, preserving the full dynamics and quantum nature of phonons, allows us to analyze in detail the renormalization of both quasiparticle bandwidth and dispersion by the electron-phonon interaction. For the two-dimensional case some of our exact data are compared with the results obtained in the framework of a recently developed finite cluster strong-coupling perturbation theory.

Type II Cepheids Pulsating in the First Overtone from the OGLE Survey

description: We report the discovery of the first type II Cepheids (BL Herculis stars) pulsating solely in the first overtone. We found two such objects among tens of millions of stars regularly observed by the OGLE survey in the Large Magellanic Cloud. Our classification and the pulsation mode identification is based on the position of these stars on the period-luminosity and color-magnitude diagrams and on the light curve analysis. We discuss why single-mode first-overtone BL Her pulsators must be very rare. For the two discovered stars we present non-linear models that successfully reproduce their light variation. These models indicate that both first-overtone pulsators should be more massive than it is typically assumed for BL Her stars, i.e. their masses should be above 0.75 Solar masses. However, the higher mass requires higher luminosity to match the observed periods of the stars, which is inconsistent with observations.

description: Patient adherence to drug therapies remains an obstacle to realizing their full therapeutic benefit. Sustained release formulations may decrease frequency of administration, potentially improving patient adherence. Implants may decrease dosing frequency to once every 5 years. However, most polymers used today are hydrophobic, limiting drug properties suitable for development. Thermoplastic poly(urethanes) (TPUs) form pores upon hydration, offering a different release mechanism. We sought to assess the range of drug diffusion rates achieved by varying hydrophilic-to-hydrophobic TPU ratio compared with poly(ethylene-co-vinyl acetate) (EVA) crystallinity; investigate the effect of drug physicochemical properties on permeability through membranes of varying TPU composition; visualize microstructural changes to the membrane across the TPU composition range; and characterize the membrane microstructure. Emtricitabine exhibited a >200-fold broader permeability range across the TPU blends than EVA grades. Varying hydrophilic content of the TPU mixture between 0- 25% (w/w) led to a negligible permeability change, whereas a >100-fold permeability change occurred between 50-55% (w/w). We observed a correlation between drug hydrophobicity and its permeability through hydrophobic-rich TPU. Conversely, drugs diffused through hydrophilic-rich TPU at similar rates, regardless of properties. Imaging revealed significant microstructure differences between hydrophobic-rich and hydrophilic-rich TPU, supporting that hydrophilic polymer domains form a continuous network above 55% (w/w) hydrophilic TPU. The large hydrophilic TPU equivalent pore radius suggests that it may modify the release of small molecular weight drugs and macromolecules. Gastroretentive formulations may reduce dosing frequency of medications otherwise taken up to 5 times per day. Acyclovir is a short half-life drug with poor colonic absorption, and conventional controlled release formulations are unable to decrease dosing frequency. We developed a modified-release acyclovir matrix tablet and surrounded it with a hydrophilic poly(urethane) layer. When hydrated, the poly(urethane) swells to a size near to or beyond the relaxed pylorus diameter, without affecting drug release rate. We demonstrated that the formulation is retained in the stomach for extended durations as it slowly releases drug, allowing for similar AUC but delayed t [subscript max] relative to a control tablet. Unlike other gastroretentive formulations, this design decouples drug release rate from gastric retention time and effectively retains in the stomach regardless of prandial state

description: This dissertation studies the determinants of return structure in the cross-section of cryptocurrencies as well as the time-series of market returns during the boom of 2017, the largest known price increase in the history of finance. The first chapter examines the cross-section of cryptocurrencies and hypothesizes and tests that, because of cryptocurrencies' unique features, common demand shocks should be the main driver of the covariance structure of cryptocurrency returns. I proxy for the degree of overlapping exposure to correlated demand shocks using a pairwise “connectivity” measure based on cryptocurrencies' trading locations. I find that this “connectivity” measure explains substantial covariation in the cross-section of cryptocurrency returns. Connected currencies exhibit substantial contemporaneous covariation. In addition, currencies connected to those that perform well outperform currencies connected to those that perform poorly by 71 basis points over the next day and 214 basis points over the next week. Evidence from new exchange listings and a quasi-natural experiment exploiting the shutdown of Chinese exchanges shows that the results cannot be explained by endogenous sorting of currencies into exchanges. Moreover, using machine learning techniques to analyze social media data, I find that the demand effects are 40 to 50% larger for currencies that rely more heavily on network externalities of user adoption. This amplified effect is consistent with the notion that demand for a cryptocurrency not only signals investment motives, but also can be perceived as user adoption that potentially affects the fundamental value of these assets. The second chapter examines the time-series of Bitcoin and the aggregate cryptocurrency returns during the boom of 2017. In particular, Bitcoin and other cryptocurrencies offer the promise of an anonymous, decentralized financial system free from banks and government intervention. Ironically, new large entities have gained centralized control over the vast majority of operations in the cryptocurrency world. One type of these large centralized entities is stable coin issuers who can act as a central bank in the crypto world by controlling the supply of money. This chapter examines the role of the largest stable coin, Tether, on Bitcoin and other cryptocurrency prices. Using algorithms to analyze blockchain data, we find that purchases with Tether are timed following market downturns and result in sizable increases in Bitcoin prices. The flow is attributable to one entity, clusters below round prices, induces asymmetric autocorrelations in Bitcoin, and suggests insufficient Tether reserves before month-ends. Rather than demand from cash investors, these patterns are most consistent with the supply-based hypothesis of unbacked digital money inflating cryptocurrency prices
