description: One-dimensional non-equilibrium models of particles subjected to a coagulation-diffusion process are important in understanding non-equilibrium dynamics, and fluctuation-dissipation relation. We consider in this paper transport properties in finite and semi-infinite one-dimensional chains. A set of particles freely hop between nearest-neighbor sites, with the additional condition that, when two particles meet, they merge instantaneously into one particle. A localized source of particle-current is imposed at the origin as well as a non-symmetric hopping rate between the left and right directions (particle drift). This model was previously studied with exact results for the particle density by Hinrichsen et al. [1] in the long-time limit. We are interested here in the crossover process between a scaling regime and long-time behavior, starting with a chain filled of particles. As in the previous reference [1], we employ the empty-interval-particle method, where the probability of finding an empty interval between two given sites is considered. However a different method is developed here to treat the boundary conditions by imposing the continuity and differentiability of the interval probability, which allows for a closed and unique solution, especially for any given initial particle configuration. In the finite size case, we find a crossover between the scaling regime and two different exponential decays for the particle density as function of the input current. Precise asymptotic expressions for the particle-density, and coagulation rate are given.

description: We consider a non-inflationary early Universe scenario in which relevant scalar perturbations get frozen out at some point, but then are defrosted and follow a long nearly Minkowskian evolution before the hot era. This intermediate stage leaves specific imprint on the CMB 3-point function, largely independent of details of microscopic physics. In particular, the CMB bispectrum undergoes oscillations in the multipole l space with roughly constant amplitude. The latter is in contrast to the oscillatory bispectrum enhanced in the flattened triangle limit, as predicted by inflation with non-Bunch--Davies vacuum. Given this and other peculiar features of the bispectrum, stringent constraints imposed by the Planck data may not apply. The CMB 3-point function is suppressed by the inverse duration squared of the Minkowskian evolution, but can be of observable size for relatively short intermediate Minkowskian stage.

title: The vocality of Sibyl Sanderson in Massenet’s Manon and Esclarmonde
Creators: name: Thompson, T. D.
Publisher: name: Royal College of Music
Year: 2016

description: This thesis explores how Sibyl Sanderson influenced Massenet’s operas Manon and Esclarmonde from the perspective of vocality, in some cases resulting in the composer making changes to the score. Research and analysis includes the study of manuscripts, annotated scores, correspondence, memoirs, pedagogic treatises, reception history, and practice. From the opposite angle, it also attempts to identify the existence and extent of any effects that performing these roles had on Sanderson. By the time of her association with Massenet, Sibyl Sanderson was a successful, young stage performer; she became one of Massenet’s primary collaborators. Documents relative to these operas suggest that the soprano’s partnership with the composer could classify her not only as an interpreter, but also as a co-creator and re-creator of these roles, respectively. Massenet afforded her credit as co-author in Esclarmonde, by including her signature on the manuscript. Her impact on Manon is evidenced through comparison of the role as sung by Sanderson versus the vocal lines used by prior and later interpreters of the role. Manon underwent significant revisions because of Sanderson. The first changes were made for her 1888 début in Brussels, and include difficult melismatic passages, increased quantity and duration of high notes, and several other revisions. One contribution to knowledge within this thesis is discussion of a revision in the 1887 manuscript, which was not included in the 1895 Nouvelle Édition, and was not addressed in previous musicological discourse. There has been conjecture about the intended recipient of the ‘Fabliau,’ the third-act aria that Massenet wrote in 1894 to replace the ‘Gavotte.’ The aria premiered in 1898, sung by Georgette Bréjean-Gravière (later Bréjean-Silver). Present research has enhanced existing arguments that the aria was intended for the dedicatee, Mlle Bréjean-Gravière. Esclarmonde was written for Sanderson’s voice to showcase her extraordinary high notes, virtuosic coloratura, and physical beauty. It could be considered one of the most demanding roles in opera, as evidenced by measured analyses within this thesis. Since she created the role, Esclarmonde has not achieved equivalent success. Through analysis of previously unexplored material, especially from the US, as well as by refuting some existing unsubstantiated claims, and by examining available sources from different perspectives, (such as quantified analyses of the roles), Sibyl Sanderson’s influence on Manon and Esclarmonde has been confirmed and support of such belief enhanced.

description: In this work, we have adopted the spin rearrangement scheme in the heavy quark limit and extensively investigated three classes of the radiative decays: $\mathfrak{M}\to (b\bar{b})+γ$, $(b\bar{b})\to \mathfrak{M}+γ$, $ \mathfrak{M} \to \mathfrak{M}^\prime+γ$, corresponding to the electromagnetic transitions between one molecular state and bottomonium, one bottomonium and molecular state, and two molecular states respectively. We also extend the same formalism to study the radiative decays of the molecular states with hidden charm. We have derived some model independent ratios when the initial or final states belong to the same spin flavor multiplet. Future experimental measurement of these ratios will test the molecular picture and explore the underlying structures of the $XYZ$ states.

description: Рассматриваются численные оценки позиций фигур на доске в партии сёги, получаемые от компьютерной программы. С использованием этих оценок предполагается рассчитать силу игрока, для чего требуется собрать данные, рассмотреть и повторить существующие подходы, предложить и реализовать свой подход, сравнить результаты. Проводится повторение подхода Феррейры, в котором на основании распределения выигрыша двух игроков рассчитывается разница их силы. При реализации подхода Ямаситы ищется зависимость между рейтингом Эло и средним ухудшением оценки позиции в результате плохого хода. Предлагается собственный подход к оценке силы игрока. Для этого рассматривается зависимость процента побед, хороших и плохих ходов, разницы оценки реальных и идеальных ходов и среднего улучшения позиции от рейтинга Эло. Предпринимаются попытки кластеризовать партии и ходы.
description: The study deals with obtaining numerical estimates of shogi pieces’ disposition on the board with the help of software. Using these estimates, the authors intend to evaluate a player’s skill. That requires collecting data, reviewing and repeating existing approaches, proposing and implementing the au-thors’ approach, and comparing the results. The difference in strength of two players is calculated based on their win distribution via re-simulation of the Ferreira approach. In implementing Yamashita’s approach, the relation between Elo rating and the average degradation of the position estimate as a result of a bad move is searched for. The authors’ approach is proposed to estimate a player’s skill. Hence, the dependence of wins, good and bad moves, the deviation of the estimates of real and ideal moves, and the average improvement of the position from the Elo rating are analyzed. The study attempts to cluster plays and moves.

description: In this presentation, I describe how specific collaboration, authentication, and sharing features of two popular, low-cost, relational database software-as-a-service (SaaS) platforms, Airtable and Notion, can be used to create open educational resources (OERs) that are easily updatable, shareable, and repurposable. Not only do these SaaS platforms provide opportunities for student assessments to be closely align with course content, but they also afford course facilitators a way to quickly verify and monitor such content-assessment alignment. Using two examples of courses taught at the UP Open University, I additionally describe how SaaS relational database platforms facilitates the use of previous student outputs as learning material for subsequent iterations of courses and drives the continuous improvement of course design.
Adler-Bardeen theorem and manifest anomaly cancellation to all orders in gauge theories

description: We reconsider the Adler-Bardeen theorem for the cancellation of gauge anomalies to all orders, when they vanish at one loop. Using the Batalin-Vilkovisky formalism and combining the dimensional-regularization technique with the higher-derivative gauge invariant regularization, we prove the theorem in the most general perturbatively unitary renormalizable gauge theories coupled to matter in four dimensions, and identify the subtraction scheme where anomaly cancellation to all orders is manifest, namely no subtractions of finite local counterterms are required from two loops onwards. Our approach is based on an order-by-order analysis of renormalization, and, differently from most derivations existing in the literature, does not make use of arguments based on the properties of the renormalization group. As a consequence, the proof we give also applies to conformal field theories and finite theories.

description: We optimize a quantum walk of multiple fermions following a quench in a spin chain to generate near ideal resources for quantum networking. We first prove an useful theorem mapping the correlations evolved from specific quenches to the apparently unrelated problem of quantum state transfer between distinct spins. This mapping is then exploited to optimize the dynamics and produce large amounts of entanglement distributed in very special ways. Two applications are considered: the simultaneous generation of many Bell states between pairs of distant spins (maximal block entropy), or high entanglement between the ends of an arbitrarily long chain (distance-independent entanglement). Thanks to the generality of the result, we study its implementation in different experimental setups using present technology: NMR, ion traps and ultracold atoms in optical lattices.

description: This paper investigates the productivity puzzle in Germany. We focus on the time-varying relationship between German output and employment growth, in particular their decoupling in recent years. We estimate a correlated unobserved components model that allows for both persistent and cyclical time variation in the employment impact of GDP as well as an autonomous employment component capturing other factors than real output. As one result, we measure a permanent decline in GDP impact on employment as well as pronounced effects of the autonomous employment component in the recent years. The development of the estimated impact parameters depends on structural change, but also on labour availability and business expectations. Beyond GDP, a high labour supply, tightness as well as moderate wages and working time reductions boosted employment growth.
Large-scale stable interacting dark energy model: Cosmological perturbations and observational constraints

description: Dark energy might interact with cold dark matter in a direct, nongravitational way. However, the usual interacting dark energy models (with constant $w$) suffer from some catastrophic difficulties. For example, the $Q\proptoρ_{\rm c}$ model leads to an early-time large-scale instability, and the $Q\proptoρ_{\rm de}$ model gives rise to the future unphysical result for cold dark matter density (in the case of a positive coupling). In order to overcome these fatal flaws, we propose in this paper an interacting dark energy model (with constant $w$) in which the interaction term is carefully designed to realize that $Q\proptoρ_{\rm de}$ at the early times and $Q\proptoρ_{\rm c}$ in the future, simultaneously solving the early-time superhorizon instability and future unphysical $ρ_{\rm c}$ problems. The concrete form of the interaction term in this model is $Q=3βH \frac{ρ_{\rm{de}}ρ_{\rm{c}}}{ρ_{\rm{de}}+ρ_{\rm{c}}}$, where $β$ is the dimensionless coupling constant. We show that this model is actually equivalent to the decomposed new generalized Chaplygin gas (NGCG) model, with the relation $β=-αw$. We calculate the cosmological perturbations in this model in a gauge-invariant way and show that the cosmological perturbations are stable during the whole expansion history provided that $β>0$. Furthermore, we use the Planck data in conjunction with other astrophysical data to place stringent constraints on this model (with eight parameters), and we find that indeed $β>0$ is supported by the joint constraint at more than 1$σ$ level. The excellent theoretical features and the support from observations all indicate that the decomposed NGCG model deserves more attention and further investigation.

description: Diffusion of innovation can be interpreted as a social spreading phenomena governed by the impact of media and social interactions. Although these mechanisms have been identified by quantitative theories, their role and relative importance are not entirely understood, since empirical verification has so far been hindered by the lack of appropriate data. Here we analyse a dataset recording the spreading dynamics of the world's largest Voice over Internet Protocol service to empirically support the assumptions behind models of social contagion. We show that the rate of spontaneous service adoption is constant, the probability of adoption via social influence is linearly proportional to the fraction of adopting neighbours, and the rate of service termination is time-invariant and independent of the behaviour of peers. By implementing the detected diffusion mechanisms into a dynamical agent-based model, we are able to emulate the adoption dynamics of the service in several countries worldwide. This approach enables us to make medium-term predictions of service adoption and disclose dependencies between the dynamics of innovation spreading and the socioeconomic development of a country.

Image-based screening methods for reducing misdiagnosis of carpometacarpal fracture and dislocation
Creators: name: Wu, Kaicheng
Publisher: name: No Publisher Supplied
Year: 2018

description: Ulnar-sided carpometacarpal joint dislocation has been commonly missed on initial examination.  The traditional diagnosis procedure manually determines the injuries based on the angles between the index metacarpal and the fourth or fifth metacarpal on the posteroanterior or lateral radiographs.  This procedure is limited since metacarpal bones are difficult to identify due to osseous overlaps.  This thesis develops an image-based screening method for reducing misdiagnosis of ulnar-sided carpometacarpal (CMC) fracture and dislocation. The screening method uses a computer-aided computational framework to calculate our proposed angles for diagnosing purpose. Each step in the computaional framework is strictly defined to ensure high re-producibility and inter- and intra- observer reliability. We develop two similar frameworks for calculating 2D and 3D angles, while 3D version is only for comparison purpose. We propose the two sets of capiate-based angles for diagnosis purpose: 1) the angle from lateral view; 2) the surrogate spatial angle calculated from lateral view angle and posteroanterior (PA) view angle: $ hat{heta} = sqrt{ heta_{ext{lateral}}^2 + heta_{ext{PA}}^2 }$.We show that by using the computational framework to calculate our proposed angles, the sreening method can effectively diagnose ulnar-sided CMC fracture and dislocation. Moreover, compared to traditional method, it can reduce the confusion associated with carpometacarpal injuries and have better sensitivity and specificity. Notably, the surrogate spatial angle further out-performs the lateral view angle in terms of differentiating between injury and non-injury cases, and the ability to detect extreme cases.

description: Recent advances enable the simultaneous computation of both attracting and repelling families of Lagrangian Coherent Structures (LCS) at the same initial or final time of interest. Obtaining LCS positions at intermediate times, however, has been problematic, because either the repelling or the attracting family is unstable with respect to numerical advection in a given time direction. Here we develop a new approach to compute arbitrary positions of hyperbolic LCS in a numerically robust fashion. Our approach only involves the advection of attracting material surfaces, thereby providing accurate LCS tracking at low computational cost. We illustrate the advantages of this approach on a simple model and on a turbulent velocity data set.

description: Cosmic rays (CRs) are protons and atomic nuclei that flow into our Solar system and reach the Earth with energies of up to ~10^21 eV. The sources of ultra-high energy cosmic rays (UHECRs) with E >~ 10^19 eV remain unknown, although there are theoretical reasons to think that at least some come from active galactic nuclei (AGNs). One way to assess the different hypotheses is by analysing the arrival directions of UHECRs, in particular their self-clustering. We have developed a fully Bayesian approach to analyzing the self-clustering of points on the sphere, which we apply to the UHECR arrival directions. The analysis is based on a multi-step approach that enables the application of Bayesian model comparison to cases with weak prior information. We have applied this approach to the 69 highest energy events recorded by the Pierre Auger Observatory (PAO), which is the largest current UHECR data set. We do not detect self-clustering, but simulations show that this is consistent with the AGN-sourced model for a data set of this size. Data sets of several hundred UHECRs would be sufficient to detect clustering in the AGN model. Samples of this magnitude are expected to be produced by future experiments, such as the Japanese Experiment Module Extreme Universe Space Observatory (JEM-EUSO).

description: Abstract:
Part I
A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.
Part II
Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:
1. Transfer between the plant leaf and the canopy bulk air and
2. Transfer between the canopy bulk air and the atmosphere.
Boundary layer concepts were applied to leaf heat transfer in both equations. Turbulent atmospheric transfer by free and forced convection were considered.
Measurements of leaf temperature and wind velocity, temperature and humidity profiles for a cucumber plot were taken during ten tests. Richardson numbers to classify atmospheric stability were determined. The neutral wind velocity profile parameters, roughness height and zero displacement height were determined by a computerized least squares technique using data from the ten tests. Calculated Richardson's numbers indicated transfer by free convection. Comparison of predicted and measured leaf temperatures revealed the forced convection prediction equations considerably over estimated leaf temperature while the free convection predictions was much more accurate.

description: We will consider the torsional completion of gravity for a background filled with Dirac matter fields, studying what happens when fermionic non-minimal coupling is taken into account: we will show that, although non-minimal couplings are usually disregarded because of their ill-defined behaviour in ultraviolet regimes, this is due to the fact that torsion is commonly neglected, whereas when torsion is not left aside, even non-minimal couplings behave properly. In detail, we will see that non-minimal coupling allows to renormalize the Dirac equation even when torsion is taken into consideration and that in some type of non-minimally coupled models parity-oddness might be present even in the gravitational sector. In addition, we will show that in the presence of the considered non-minimal coupling, torsion is able to evade cosmological singularities as it can happen in the minimal coupling case and in some other non--minimally coupled theory. In the course of the paper, we shall consider a specific interaction as prototype to study this fermionic non-minimal coupling, but we will try to present results that do not depend on the actual structure of the non-minimal couplings by investigating alternative types of interaction.

description: Digitalization, as well as sustainability, are gaining increased relevance and have attracted significant attention in research and practice. However, the research already published about this topic examining digitalization in the retail sector does not consider the acceptance of related innovations, nor their impact on sustainability. Therefore, this article critically analyzes the acceptance of customers towards digital technologies in fashion stores as well as their impact on sustainability in the textile industry. The comprehensive analysis of the literature and the current state of research provide the basis of this paper. Theoretical models, such as the Technology-Acceptance-Model (TAM) and the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) enable the evaluation of expectations and acceptance, as well as the assessment of possible inhibitory factors for the subsequent descriptive and statistical examination of the acceptance of digital technologies in fashion stores. The research on this subject was examined in a quantitative way. The key findings show that customers do accept digital technologies in fashion stores. The final part of this contribution describes the innovative Digitalization 4 Sustainability Framework which shows that digital technologies at the point of sale (PoS) in fashion stores could have a positive impact on sustainability. Overall, this paper shows that it is particularly important for fashion stores to concentrate on their individual strengths and customer needs as well as to indicate a more sustainable way by using digital technologies, in order to achieve added value for the customers and to set themselves apart from the competition while designing a more sustainable future. Moreover, fashion stores should make it a point of their honor to harness the power of digitalization for sake of sustainability and economic value creation.

description: We study the role of accidental symmetries in two-dimensional (0,2) superconformal field theories obtained by RG flow from (0,2) Landau-Ginzburg theories. These accidental symmetries are ubiquitous, and, unlike in the case of (2,2) theories, their identification is key to correctly identifying the IR fixed point and its properties. We develop a number of tools that help to identify such accidental symmetries in the context of (0,2) Landau-Ginzburg models and provide a conjecture for a toric structure of the SCFT moduli space in a large class of models. We also give a self-contained discussion of aspects of (0,2) conformal perturbation theory.

description: Atomtronics is an emerging interdisciplinary field that seeks new functionality by creating devices and circuits where ultra-cold atoms, often superfluids, play a role analogous to the electrons in electronics. Hysteresis is widely used in electronic circuits, e.g., it is routinely observed in superconducting circuits and is essential in rf-superconducting quantum interference devices [SQUIDs]. Furthermore, hysteresis is as fundamental to superfluidity (and superconductivity) as quantized persistent currents, critical velocity, and Josephson effects. Nevertheless, in spite of multiple theoretical predictions, hysteresis has not been previously observed in any superfluid, atomic-gas Bose-Einstein condensate (BEC). Here we demonstrate hysteresis in a quantized atomtronic circuit: a ring of superfluid BEC obstructed by a rotating weak link. We directly detect hysteresis between quantized circulation states, in contrast to superfluid liquid helium experiments that observed hysteresis directly in systems where the quantization of flow could not be observed and indirectly in systems that showed quantized flow. Our techniques allow us to tune the size of the hysteresis loop and to consider the fundamental excitations that accompany hysteresis. The results suggest that the relevant excitations involved in hysteresis are vortices and indicate that dissipation plays an important role in the dynamics. Controlled hysteresis in atomtronic circuits may prove to be a crucial feature for the development of practical devices, just as it has in electronic circuits like memory, digital noise filters (e.g., Schmitt triggers), and magnetometers (e.g., SQUIDs).

Uncovering the tooth: interventive dental therapy in Ancient Egypt

description: Since the early twentieth century, scholars have suggested that the ancient Egyptians were highly advanced and organised in their practice of medicine, to the extent of possessing a specialised branch of dentistry from as early as the Old Kingdom (c. 2686 – 2181 BC). An extremely small corpus of osteological specimens purported to exhibit evidence of interventive dental therapy has been used to support this claim. However, the therapeutic interpretations of many of the specimens have been disputed and it is clear that further scientific analysis is required to clarify our understanding of the evidence. Several historiographical issues have also influenced past scholarship and warrant review, including apocryphal ‘archaeological discoveries’ relating to ancient Egyptian dental therapy, and inaccurate secondary reports concerning the osteological corpus. Furthermore, it has been suggested that the Egyptians were the first ancient culture to produce and employ dental bridges for the therapeutic purpose of stabilising loose or exfoliated teeth within the dentition; however, scholars have neglected to critically consider the geographical transmission of ideas and technology relating to dental therapy in antiquity. Utilising an embodied and biocultural approach, this project appraises the available osteological evidence relating to ancient Egyptian dental therapy within the timeframe of the Old Kingdom – Graeco-Roman Period (c. 2686 BC – AD 323), to assess the accuracy of previous therapeutic interpretations. The investigation reveals that only three specimens can plausibly be attributed to dental therapy including the Tura el-Asmant Bridge and two carious lesion fillings. The appraisal also elucidates the need for continued scientific analysis of the corpus and addresses the historiographical issues apparent within the discourse. To determine the validity of past suggestions that the ancient Egyptians were the first culture to employ dental bridges, this project additionally investigates the larger corpus of dental devices from antiquity, including Phoenician, Etruscan, Greek and Roman devices. This research instead indicates that the Etruscans were the first culture to employ dental devices; however, the development of this technology was significantly influenced by regular cultural exchange in the ancient world.
A random version of Sperner's theorem

description: Let $\mathcal{P}(n)$ denote the power set of $[n]$, ordered by inclusion, and let $\mathcal{P}(n,p)$ be obtained from $\mathcal{P}(n)$ by selecting elements from $\mathcal{P}(n)$ independently at random with probability $p$. A classical result of Sperner asserts that every antichain in $\mathcal{P}(n)$ has size at most that of the middle layer, $\binom{n}{\lfloor n/2 \rfloor}$. In this note we prove an analogous result for $\mathcal{P} (n,p)$: If $pn \rightarrow \infty$ then, with high probability, the size of the largest antichain in $\mathcal{P}(n,p)$ is at most $(1+o(1)) p \binom{n}{\lfloor n/2 \rfloor}$. This solves a conjecture of Osthus who proved the result in the case when $pn/\log n \rightarrow \infty$. Our condition on $p$ is best-possible. In fact, we prove a more general result giving an upper bound on the size of the largest antichain for a wider range of values of $p$.

description: Using gauge/gravity duality, we explore a class of states of two CFTs with a large degree of entanglement, but with very weak local two-sided correlation. These states are constructed by perturbing the thermofield double state with thermal-scale operators that are local at different times. Acting on the dual black hole geometry, these perturbations create an intersecting network of shock waves, supporting a very long wormhole. Chaotic CFT dynamics and the associated fast scrambling time play an essential role in determining the qualitative features of the resulting geometries.

description: We have performed our data analysis of the observations by Swift and Fermi satellites in order to probe the induced gravitational collapse (IGC) paradigm for GRBs associated with supernovae (SNe), in the "terra incognita" of GRB 130427A. We compare and contrast our data analysis with those in the literature. We have verified that the GRB 130427A conforms to the IGC paradigm by examining the power law behavior of the luminosity in the early $10^4$ s of the Swift-XRT observations. This has led to the successful prediction of the occurrence of SN 2013cq and to the identification of the four different episodes of the "binary driven hypernovae" (BdHNe). The exceptional quality of the data has allowed the identification of novel features in Episode 3 including: a) the confirmation and the extension of the existence of the recently discovered "nested structure" in the late X-ray luminosity in GRB 130427A, as well as the identification of a spiky structure at $10^2$ s in the cosmological rest-frame of the source; b) a power law emission of the GeV luminosity light curve and its onset at the end of Episode 2 c) different Lorentz $Γ$ factors for the emitting regions of the X-ray and GeV emissions in this Episode 3. These results make it possible to test the details of the physical and astrophysical regimes at work in the BdHNe: 1) a newly born neutron star and the supernova ejecta, originating in Episode 1, 2) a newly formed black hole originating in Episode 2, and 3) the possible interaction among these components, observable in the standard features of Episode 3.
