description: We conjecture what the cone of hypercohomology tables of bounded complexes of coherent sheaves on projective spaces are, when we have specified regularity conditions on the cohomology sheaves of this complex and its dual. There is an injection from the this cone into the cone of homological data sets of squarefree modules over a polynomial ring $\kk[x_1, \ldots, x_n]$, and we conjecture that this is an isomorphism: The Tate resolutions of a complex of coherent sheaves and the exterior coalgebra on $\langle x_1, \ldots, x_n \rangle$ may be amalgamated together to form a complex of free $\Sym(\oplus_i x_i \te W^*)$-modules, a procedure introduced by Cox and Materov. Via a reduction $\oplus_i x_i \te W^* \pil \oplus_i x_i \te \kk$ we get a complex of free modules over $\kk[x_1, \ldots, x_n]$ The extremal rays in the cone of squarefree complexes are conjecturally given by triplets of pure free squarefree complexes introduced in \cite{FlTr}. We describe the corresponding classes of hypercohomology tables, a class which generalizes vector bundles with supernatural cohomology. We also show how various pure resolutions in the literature, like resolutions of modules supported on determinantal varieties, and tensor complexes, may be obtained by the first part of the procedure.

description: Markovian open quantum systems display complicated relaxation dynamics. The spectral gap of the Liouvillian characterizes the asymptotic decay rate towards the steady state, but it does not necessarily give a correct estimate of the relaxation time because the crossover time to the asymptotic regime may be too long. We here give a rigorous upper bound on the transient decay of auto-correlation functions in the steady state by introducing the symmetrized Liouvillian gap. The standard Liouvillian gap and the symmetrized one are identical in an equilibrium situation but differ from each other in the absence of the detailed balance condition. It is numerically shown that the symmetrized Liouvillian gap always give a correct upper bound on the decay of the auto-correlation function, but the standard Liouvillian gap does not.

description: The Standard Model Lagrangian has an approximate scale symmetry in the high-energy limit. This observation can be included in the fundamental principle of the ultimate theory of Nature as the requirement of the exact quantum scale invariance. In this setup, all low-energy particle phenomenology can be obtained as a result of the spontaneous breaking of scale symmetry leading to the presence of the extra massless scalar field -- the dilaton. We explore the scenario in which this field is capable of solving the strong CP-problem in QCD in a similar way as in QCD axion models. The dilaton, playing the role of the axion, is coupled to the QCD sector and acquires a mass term due to non-perturbative breaking of scale symmetry. We show that the dilaton can form dark matter after the low-scale inflation. As a proof of concept, we construct a model of Higgs-driven inflation consistently realising the axion-like dilaton dark matter production compatible with the CMB data.

description: Degeneracies among parameters of the cosmological model are known to drastically limit the information contained in the matter distribution. In the first paper of this series, we shown that the cosmic web environments; namely the voids, walls, filaments and nodes; can be used as a leverage to improve the real-space constraints on a set of six cosmological parameters, including the summed neutrino mass. Following-upon these results, we propose to study the achievable constraints of environment-dependent power spectra in redshift space where the velocities add up information to the standard two-point statistics by breaking the isotropy of the matter density field. A Fisher analysis based on a set of thousands of Quijote simulations allows us to conclude that the combination of power spectra computed in the several cosmic web environments is able to break some degeneracies. Compared to the matter monopole and quadrupole information alone, the combination of environment-dependent spectra tightens down the constraints on key parameters like the matter density or the summed neutrino mass by up to a factor of $5.5$. Additionally, while the information contained in the matter statistic quickly saturates at mildly non-linear scales in redshift space, the combination of power spectra in the environments appears as a goldmine of information able to improve the constraints at all the studied scales from $0.1$ to $0.5$ $h$/Mpc and suggests that further improvements are reachable at even finer scales.

description: Lattice reconstruction and corresponding strain accumulation play a key role in defining the electronic structure of two-dimensional moiré superlattices, including those of transition metal dichalcogenides (TMDs). Imaging of TMD moirés has so far provided a qualitative understanding of this relaxation process in terms of interlayer stacking energy, while models of the underlying deformation mechanisms have relied on simulations. Here, we use interferometric four-dimensional scanning transmission electron microscopy to quantitatively map the mechanical deformations through which reconstruction occurs in small-angle twisted bilayer MoS2 and WSe2/MoS2 heterobilayers. We provide direct evidence that local rotations govern relaxation for twisted homobilayers, while local dilations are prominent in heterobilayers possessing a sufficiently large lattice mismatch. Encapsulation of the moiré layers in hBN further localizes and enhances these in-plane reconstruction pathways, suppressing out-of-plane corrugation. We also find that extrinsic uniaxial heterostrain, which introduces a lattice constant difference in twisted homobilayers, leads to accumulation and redistribution of reconstruction strain, demonstrating another route to modify the moiré potential.

description: The past fifty years have seen the emergence of a new field of research in physics, the study of matter at extreme temperatures and densities. The theory of strong interactions, quantum chromodynamics (QCD), predicts that in this limit, matter will become a plasma of deconfined quarks and gluons -- the medium which made up the early universe in the first 10 microseconds after the big bang. High energy nuclear collisions are expected to produce short-lived bubbles of such a medium in the laboratory. I survey the merger of statistical QCD and nuclear collision studies for the analysis of strongly interacting matter in theory and experiment.

description: Stokes drift is a classical fluid effect in which travelling waves transfer momentum to tracers of the fluid, resulting in a non-zero drift velocity in the direction of the incoming wave. This effect is the driving mechanism allowing particles, i.e. impurities, to be transported by the flow; in a classical (viscous) fluid this happens usually due to the presence of viscous drag forces. Because of the eventual absence of viscosity in quantum fluids, impurities are driven by inertial effects and pressure gradients only. We present theoretical predictions of a Stokes drift analogous in quantum fluids for classical impurities obtained using multi-time analytical asymptotic expansions. We find that, at the leading order, the drift direction and amplitude depend on the initial impurity position with respect to the wave phase; at the second order, dominant after averaging over initial conditions, our theoretical model recovers the classical Stokes drift but with a coefficient that depends on the relative particle-fluid density ratio. Numerical simulations of a two-dimensional Gross-Piteaveskii equation coupled with a classical impurity corroborate our findings. Our predictions are experimentally testable, for instance, using fluids of light obtained in photorefractive crystals.

Informing the conservation and restoration of a keystone species : the larval behaviour of the European oyster Ostrea edulis

description: The European oyster Ostrea edulis is a keystone species that is internationally recognised as ‘threatened and declining’ in the North-East Atlantic and several nations have adopted strategies for its conservation and restoration. The overall goal of the present work was to inform conservation and restoration efforts. The purpose of this thesis, therefore, was to study the larval behaviour and ecology of O. edulis in as much as is relevant to the dispersal of this species. Specifically, the larvae’s vertical distribution, swimming speeds, settlement preferences and pelagic duration were studied in laboratory experiments. Most larvae concentrated at the bottom of the aquarium, independently of the developmental stage, light, food or temperature. In addition, larvae behaved actively in ~50% of all bottom observations, indicating a behavioural function other than resting. Advection close to the seabed is known to be slower than in any other part of the water column. The observed demersal behaviour would therefore most likely reduce dispersal from natal populations and enhance self-recruitment. At the surface, larvae frequently formed aggregations. In the water column, larvae swam with high vertical directionality and their distribution was homogenous. Swimming speeds ranged from 0.001 mm/s to 9.07 mm/s. O. edulis larvae settled preferentially among conspecifics (100% in < 24h), and if conspecifics were absent, larvae also settled in response to habitat-associated biofilms (81% of settlement after a 45h delay). Sterile shells and terrestrial stones did not induce more settlement than control treatments (0-14% settlement). Pelagic duration was strongly dependent on temperature, food and a suitable settlement cue. In the absence of an appropriate settlement cue, 80% of larvae delayed metamorphosis for up to 14 days, when the experiment was terminated. In contrast, 95-100% of larvae delaying their metamorphosis settled when presented with a conspecific. Such a delay in metamorphosis enhances the risk of predation and, ultimately, of losing most larvae to mortality if target habitats are absent. The results of this thesis provide strong evidence that O. edulis larvae are targeting their own beds, and that the behaviour of larvae plays a crucial role in their dispersal and successful recruitment. Restoring European oyster beds at a scale that is large and dense enough to promote the retention of larvae may be crucial to the success of restoration efforts.

description: We develop a framework to derive consistency constraints on gravitational Regge amplitudes based on the finite energy sum rules (FESRs), which directly connect gravitational Regge amplitudes at a finite ultraviolet scale with infrared physics without suffering from super-Planckian physics. For illustration, we consider four-point scattering of an identical massless scalar coupled to gravity. First, we derive multiple FESRs without relying on the $s\text{-}t\text{-}u$ permutation invariance. We then make use of FESRs, crossing symmetry, and other principles such as unitarity, to derive bounds on the Regge parameters. The bounds result in infrared finite gravitational positivity bounds in four spacetime dimensions.

description: We consider the capture of a muon on a deuteron. An uncertainty analysis of the dominant channels is important for a careful analysis of forthcoming experimental data. We quantify the theoretical uncertainties of chiral effective-field-theory predictions of the muon-deuteron capture rate from the relevant neutron-neutron partial wave channels in the final state. We study the dependence on the cutoff used to regularize the interactions, low-energy constants calibrated using different fitting data and strategies, and truncation of the effective-field-theory expansion of the currents. Combining these approaches gives as an estimate of $Γ^{1/2}_{μd} = 399.1 \pm 7.6 \pm 4.4$ s$^{-1}$ for capture from the atomic doublet state, and $Γ^{3/2}_{μd} = 12.31 \pm 0.47 \pm 0.04$ s$^{-1}$ for capture from the quartet state.

Levitation in an "almost" electrostatic field

Subjects: subject: General Physics (physics.gen-ph)

description: It is well known that a charged particle cannot be in stable equilibrium in a purely electrostatic field. The situation is different in a magnetostatic field; consequently, magnetic levitation is possible while electrostatic levitation is not. In this paper, motivated by an analogy with a mechanical system, we show that the addition of a small oscillating electrical field to an otherwise electrostatic configuration leads to the stabilisation of unstable equilibrium points. Therefore, levitation becomes possible in an "almost electrostatic" field.

description: Quantum illumination utilizes an entanglement-enhanced sensing system to outperform classical illumination in detecting a suspected target, despite the entanglement-breaking loss and noise. However, practical and optimal receiver design to fulfil the quantum advantage has been a long open problem. Recently, [arXiv:2207.06609] proposed the correlation-to-displacement (`C$\rightarrow$D') conversion module to enable an optimal receiver design that greatly reduces the complexity of the previous known optimal receiver [Phys. Rev. Lett. {\bf 118}, 040801 (2017)]. There, the analyses of the conversion module assume an ideal target with a known reflectivity and a fixed return phase. In practical applications, however, targets often induce a random return phase; moreover, their reflectivities can have fluctuations obeying a Rayleigh-distribution. In this work, we extend the analyses of the C$\rightarrow$D module to realistic targets and show that the entanglement advantage is maintained albeit reduced. In particular, the conversion module allows exact and efficient performance evaluation despite the non-Gaussian nature of the quantum channel involved.

Αρχικά πραγματοποιήθηκε η μοντελοποίηση της παραγωγικής διαδικασίας με χρήση δικτύων Petri. Κατά την μοντελοποίηση υλοποιήθηκαν τρία μοντέλα παραγωγής των πέντε διαφορετικών προϊόντων που παράγονται στη συγκεκριμένη βιομηχανία, όπως αυτά προέκυψαν από την συσχέτιση τους και τις κοινές εργασίες που περιλαμβάνουν. Τα μοντέλα μελετήθηκαν εκτεταμένα με σκοπό να εντοπισθούν οι εργασίες εκείνες που περιορίζουν την αποδοτικότητα του συστήματος. Στη συνέχεια, υλοποιήθηκε ένα ρεαλιστικό σενάριο εγκατάστασης στη γραμμή παραγωγής μιας σύγχρονης μονάδας στεγνώματος των δερμάτων. Επιπλέον, εξετάστηκε ένα δεύτερο σενάριο που αφορά τη χρήση σύγχρονου εξοπλισμού διαπλάτυνσης των δερμάτων. Εκτελέστηκαν προσομοιώσεις των μοντέλων και για τα τρία σενάρια με στόχο τη συγκριτική τους αξιολόγηση και τον υπολογισμό ενός αριθμού παραμέτρων που είναι αναγκαίες και στα επόμενα στάδια της εργασίας.
Στη συνέχεια πραγματοποιήθηκε πρόβλεψη, με χρήση μαθηματικών μεθόδων, της ζήτησης δερμάτων για το έτος 2015, χρησιμοποιώντας τα δεδομένα της ζήτησης των τεσσάρων προηγούμενων ετών (2011-2014). Εφαρμόστηκαν τέσσερις διαφορετικές μέθοδοι πρόβλεψης και τα αποτελέσματα τους συγκρίθηκαν και αξιολογήθηκαν με την χρήση έξι διαφορετικών κριτηρίων. Επιλέχθηκε η μέθοδος πρόβλεψης που παρουσίαζε την καλύτερη προσαρμογή στην τάση αλλά και στην εποχικότητα.
Στο τρίτο μέρος της παρούσας διπλωματικής εργασίας, καταστρώθηκε και επιλύθηκε γραμμικό πρόβλημα μεγιστοποίησης του κέρδους. Στο μοντέλο που διαμορφώθηκε εισήχθησαν όλοι οι τεχνικοί και φυσικοί περιορισμοί, όπως π.χ. ο περιορισμός του συγκεκριμένου αριθμού δερμάτων ανά παρτίδα, γεγονός που μετέτρεψε το πρόβλημα σε γραμμικό πρόβλημα μικτού ακεραίου (MILP). Εξετάστηκαν τα εναλλακτικά σενάρια λειτουργίας μεταβάλλοντας αναλόγως τις παραμέτρους (χρονικές, ποσοτικές και οικονομικές) που επηρεάζονταν. Τα αποτελέσματα της επίλυσης του γραμμικού προβλήματος παρείχαν το πλάνο ετήσιας παραγωγής και αποθεματοποίησης για κάθε σενάριο λειτουργίας της βιομηχανίας, ώστε το ετήσιο κέρδος της να είναι το μέγιστο δυνατό.
Στο τελευταίο μέρος της εργασίας συνοψίζονται τα συμπεράσματα και οι προτάσεις βελτίωσης της παραγωγικής διαδικασίας και κατά συνέπεια αύξησης του κέρδους της υπό μελέτη βιομηχανίας. Επιπλέον παρουσιάζονται επόμενα βήματα της υλοποιούμενης μελέτης.

description: Filamentary structures are ubiquitous from large-scale molecular clouds (few parsecs) to small-scale circumstellar envelopes around Class 0 sources (~1000 AU to ~0.1 pc). In particular, recent observations with the Herschel Space Observatory emphasize the importance of large-scale filaments (few parsecs) and star formation. The small-scale flattened envelopes around Class 0 sources are reminiscent of the large-scale filaments. We propose an observationally derived scenario for filamentary star formation that describes the evolution of filaments as part of the process for formation of cores and circumstellar envelopes. If such a scenario is correct, small-scale filamentary structures (0.1 pc in length) with higher densities embedded in starless cores should exist, although to date almost all the interferometers have failed to observe such structures. We perform synthetic observations of filaments at the prestellar stage by modeling the known Class 0 flattened envelope in L1157 using both the Combined Array for Research in Millimeter-wave Astronomy (CARMA) and the Atacama Large Millimeter/Submillimeter Array (ALMA). We show that with reasonable estimates for the column density through the flattened envelope, the CARMA D-array at 3mm wavelengths is not able to detect such filamentary structure, so previous studies would not have detected them. However, the substructures may be detected with CARMA D+E array at 3 mm and CARMA E array at 1 mm as a result of more appropriate resolution and sensitivity. ALMA is also capable of detecting the substructures and showing the structures in detail compared to the CARMA results with its unprecedented sensitivity. Such detection will confirm the new proposed paradigm of non-spherical star formation.

description: Network-assisted full-duplex (NAFD) distributed massive multiple input multiple output (M-MIMO) enables the in-band full-duplex with existing half-duplex devices at the network level, which exceptionally improves spectral efficiency. This paper analyzes the impact of low-resolution analog-to-digital converters (ADCs) on NAFD distributed M-MIMO and designs an efficient bit allocation algorithm for low-resolution ADCs. The beamforming training mechanism relieves the heavy pilot overhead for channel estimation, which remarkably enhances system performance by guiding the interference cancellation and coherence detection. Furthermore, closed-form expressions for spectral and energy efficiency with low-resolution ADCs are derived. The multi-objective optimization problem (MOOP) for spectral and energy efficiency is solved by the deep Q network and the non-dominated sorting genetic algorithm II. The simulation results corroborate the theoretical derivation and verify the effectiveness of introducing low-resolution ADCs in NAFD distributed M-MIMO systems. Meanwhile, a set of Pareto-optimal solutions for ADC accuracy flexibly provide guidelines for deploying in a practical NAFD distributed M-MIMO system.

description: In 1246, when Pope Innocent IV saw embroidered copes and mitres which were made in England, he exclaimed; “England is for us surely a garden of delights, truly an inexhaustible well; and from there where so many things abound...” Embroidery made between 1200-1350 in England, known as opus anglicanum, was internationally recognized, traded, gifted, collected, and coveted. The technical skill combined with a distinct aesthetic resulted in an iconic textile brand. Though first described as a brand in the context of contemporary imitated textiles, I extend this understanding by close visual analyses and archival readings. “Opus anglicanum: The Visual Language, Liturgical Rituals, and Gifting of a Medieval English Brand” argues for a quadripartite examination of the opus anglicanum brand, grounded in luxury brand theory. I articulate the technical and aesthetic hallmarks of the brand by examining archival records of embroiderers and the specific aspects of their work which differentiated opus anglicanum from other contemporary textile decorations. I then evaluate the opus anglicanum brand aesthetic by a close visual reading of its background designs and popular motifs, through which emerges the enduring relationship between manuscript illumination and embroidery design. As the majority of extant opus anglicanum textiles are ecclesiastic vestments, I then assess these textiles in the context of contemporary liturgical writings and rituals. As archival evidence indicates, opus anglicanum textiles were often presented as gifts. Therefore, I conclude by studying the effect of medieval English embroidery in the context of gift-giving rituals. This dissertation, while grounded in both medieval and modern scholarship, reevaluates these textiles and argues that the enduring legacy of opus anglicanum is due to its identity as a medieval brand.

description: We demonstrate that the absence of stable quasiparticle excitations on parts of the Fermi surface, similar to the "nodal-antinodal dichotomy" in underdoped cuprate superconductors, can be reproduced in models of strongly correlated electrons defined via a holographic dual. We show analytically that the anisotropy of the quantum critical continuum, which is a feature of these models, may lead to washing out the quasiparticle peak in one direction while leaving it intact in the perpendicular one. The effect relies on the qualitatively different scaling of the self-energy in different directions. Using the explicit example of the anisotropic Q-lattice model, we demonstrate how this effect emerges due to specific features of the near horizon geometry of the black hole in the dual description.

description: Nach fast 58 Jahren Regierungsbeteiligung der CDU kam 2011 in Baden-Württemberg mit der Koalition aus Grünen und SPD erstmals in einem deutschen Bundesland eine Koalition unter einem grünen Ministerpräsidenten zustande. Die Frage, die in diesem Artikel analysiert werden soll, ist, inwieweit die neu ins Amt gekommene grün-rote Landesregierung den Anpassungsprozess an die Schuldenbremse in der Finanzpolitik anders vollzog, als dies der Parteiendifferenztheorie zufolge bei einer bürgerlichen Regierungsbeteiligung zu erwarten gewesen wäre. Diese Fragestellung soll dabei in vier Schritten beantwortet werden. Zunächst sollen die Wahlprogramme zur Landtagswahl 2011 von Grünen, SPD und CDU miteinander sowie mit dem grün-roten Koalitionsvertrag verglichen werden. Anschließend soll zweitens ein Überblick über die Ausgabenprioritäten der Landesregierung Kretschmann gegeben werden. Drittens werden die wesentlichen tatsächlich getätigten Reformen der grün-roten Landesregierung im Bereich der Finanzpolitik zur Vorbereitung der Einhaltung der Schuldenbremse, nach der alle Bundesländer spätestens 2020 einen ausgeglichenen Haushalt präsentieren müssen, analysiert werden. Abschließend soll viertens eine Einordnung der durchgeführten Reformen der ersten grün-roten Landesregierung im Vorfeld der Einhaltung der Regulierungsvorgaben durch die Schuldenbremse vorgenommen werden.

description: To tackle the exponentially increasing throughput of Next-Generation Sequencing (NGS), most of the existing short-read aligners can be configured to favor speed in trade of accuracy and sensitivity. SOAP3-dp, through leveraging the computational power of both CPU and GPU with optimized algorithms, delivers high speed and sensitivity simultaneously. Compared with widely adopted aligners including BWA, Bowtie2, SeqAlto, GEM and GPU-based aligners including BarraCUDA and CUSHAW, SOAP3-dp is two to tens of times faster, while maintaining the highest sensitivity and lowest false discovery rate (FDR) on Illumina reads with different lengths. Transcending its predecessor SOAP3, which does not allow gapped alignment, SOAP3-dp by default tolerates alignment similarity as low as 60 percent. Real data evaluation using human genome demonstrates SOAP3-dp's power to enable more authentic variants and longer Indels to be discovered. Fosmid sequencing shows a 9.1 percent FDR on newly discovered deletions. SOAP3-dp natively supports BAM file format and provides a scoring scheme same as BWA, which enables it to be integrated into existing analysis pipelines. SOAP3-dp has been deployed on Amazon-EC2, NIH-Biowulf and Tianhe-1A.
