Turbulence model for simulation of the flame front propagation in SNIa
Creators: name: Glazyrin, S.
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Turbulence significantly influences the dynamics of flame in SNIa. The large Reynolds number makes impossible the direct numerical simulations of turbulence, and different models of turbulence have to be used. Here we present the simulations with the $k$-$ε$ model. The turbulence is generated by the RTL instability and crucially influences flame front velocity, resulting in $v_{\rm flame}\sim 300$ km/s. The model reproduces turbulent properties in low-dimensional simulations and can be used for the low-cost studies.

description: X-Ray microtomography was used to follow the coarsening of the structure of a ternary silicate glass experiencing phase separation in the liquid state. The volumes, surfaces, mean and Gaussian curvatures of the domains of minority phase were measured after reconstruction of the 3D images and segmentation. A linear growth law of the characteristic length scale $\ell \sim t$ was observed. A detailed morphological study was performed. While dynamical scaling holds for most of the geometrical observables under study, a progressive departure from scaling invariance of the distributions of local curvatures was evidenced. The latter results from a gradual fragmentation of the structure in the less viscous phase that also leads to a power-law size distribution of isolated domains.

Spectral Formulation of the Elastodynamic Boundary Integral Equations for Bi-material Interfaces

description: A spectral formulation of the plane-strain boundary integral equations for an interface between dissimilar elastic solids is presented. The boundary integral equations can be written in two equivalent forms: (a) The tractions can be written as a space-time convolution of the displacement continuities at the interface (Budiansky and Rice, 1979) (b) The displacement discontinuities can be written as a space-time convolution of the tractions at the interface (Kostrov, 1966). Prior work on spectral formulation of the boundary integral equations has adopted the former as the starting point. The present work has for its basis the latter form based on a space-time convolution of the tractions. Tractions and displacement components are given a spectral representation in the spatial coordinate along the interface. The radiation damping term is then explicitly extracted to avoid singularities in the convolution kernels. With the spectral forms introduced, the space-time convolutions reduce to convolutions in time for each Fourier mode. Due to continuity of tractions at the interface, this leads to a simpler formulation and form of the convolution kernels in comparison to the formulation involving convolutions over the slip and opening history at the bi-material interface. The convolution kernels are validated by studying some model problems to which analytical solutions are known. When coupled with a cohesive law or a friction law at the interface, the formulation proposed here is of wide applicability for studying spontaneous rupture propagation.

description: The timing of short extreme rainstorm, which was usually thought to occur on midsummer afternoons, was investigated to improve future mitigation options for infrastructure and safety from localised flash flooding. Using a peak-over-threshold approach, the timing of 10- and 60-min extreme events was filtered from high-resolution rainfall series assessing diurnal, seasonal, and annual distributions and analysed for spatial variations and prevailing atmospheric circulation types (CTs). The diurnal distribution showed a clear deviation from that of the entire rainfall regime. A complex spatial pattern was identified with distinct timing signatures of storms in the northern (mostly afternoon) and southern regions (a bimodal distribution with a second peak in the early morning) of Germany and a more homogenous diurnal distribution of events across the central regions. Most storms occurred in summer, but 42% of 10-min events occurred outside the summer months (June–July–August). A distinct annual clustering of extremes was identified, which varied distinctly between the 10- and 60-min extremes, indicating that the sub-hourly and hourly events were far from running conterminously. The timing of extreme events on the investigated time scales was not dominated by the occurrence of specific CTs in most cases, suggesting that other factors control these extremes.
title: Detection of neurological abnormalities in adolescents and adults with phenylketonuria
Creators: name: Cleary, Maureen Anne
Publisher: name: University of Glasgow
Year: 1997

description: Phenylketonuria (PKU) is an inborn error of amino acid metabolism. It occurs in approximately 1 in 10,000 of the United Kingdom population and follows an autosomal recessive pattern of inheritance. The disease results from a deficiency or defect of the enzyme phenylalanine hydroxylase which converts phenylalanine (phe) to tyrosine (tyr). In PKU there is an accumulation of phenylalanine that is toxic to the developing brain and causes mental retardation, spasticity and seizures. The treatment of PKU is the adherence to a special phe-restricted diet with amino acid, vitamin and mineral supplements. There are guidelines for the duration of dietary therapy in the United Kingdom produced by the Medical Research Council (MRC) Steering Committee on Phenylketonuria. These guidelines have been reviewed recently and lifelong diet is now recommended. This study began prior to the publication of these recommendations at a time when many centres discontinued diet in early adolescence. The rationale for stopping diet in adolescence is that the majority of brain development is complete by the end of childhood. The risks to the brain of the subsequent rise in phe levels in adolescence and adulthood after diet cessation remain unclear. The impetus to this study was the emergence of reports of adults with PKU (who had discontinued diet after childhood) developing new neurological signs such as spasticity of the limbs. Magnetic resonance imaging (MRI) of the brain in these patients showed an abnormal signal in the cerebral white matter and it was initially suggested that the MRI changes depicted the structural abnormalities causing the loss of function in these individuals. It was postulated by these authors that elevated phe levels in later life had a toxic effect on myelin and that adults with PKU were at risk of later onset neurological damage. This study was designed to obtain more information about brain function in adults with PKU who had stopped dietary treatment and to attempt to ascertain whether the MRI abnormalities described in several adults had any clinical significance.

description: Electroweak processes in high-energy lepton collisions are considered in a situation where the incident center-of-mass energy lies below the reaction threshold, but is boosted to the required level by subsequent laser acceleration. Within the framework of laser-dressed quantum field theory, we study the laser-boosted process $\ell^+ \ell^- \to HZ^0$ in detail and specify the technical demands needed for its experimental realization. Further, we outline possible qualitative differences to field-free processes regarding the detection of the produced Higgs bosons.

description: Urban areas tend to be warmer than their rural surroundings, well-known as the “urban heat island” effect. Higher nocturnal air temperature (Tair) is associated with adverse effects on human health, higher mortality rates, and higher energy consumption. Prediction of the spatial distribution of Tair is a step toward the “Smart City” concept, providing an early warning system for vulnerable populations. The study of the spatial distribution of urban Tair was thus far limited by the low spatial resolution of traditional data sources. Volunteered geographic information provides alternative data with higher spatial density, with citizen weather stations monitoring Tair continuously in hundreds or thousands of locations within a single city. In this article, the aim was to predict the spatial distribution of nocturnal Tair in Berlin, Germany, one day in advance at a 30-m resolution using open-source remote sensing and geodata from Landsat and Urban Atlas, crowdsourced Tair data, and machine learning (ML) methods. Results were tested with a “leave-one-date-out” training scheme (testingcrowd) and reference Tair data (testingref). Three ML algorithms were compared-Random Forest (RF), Stochastic Gradient Boosting, and Model Averaged Neural Network. The optimal model based on accuracy and computational speed is RF, with an average root mean square error (RMSE) for testingcrowd of 1.16 °C (R 2 = 0.512) and RMSE for testingref of 1.97 °C (R 2 = 0.581). Overall, the most important geographic information system (GIS) predictors were morphometric parameters and albedo. The proposed method relies on open-source datasets and can, therefore, be adapted to many cities worldwide.

title: The adaptation of literature to the musical stage: The best of the Golden Age
Creators: name: Bratten, Lee Ann
Publisher: name: University of Glasgow
Year: 1997
Subjects: subject: Music history, theater history.

description: Musicals during the Golden Age of Broadway - the two decades between 1940 and 1960 - diverged from their reputation as spectacularly staged plays interrupted by song, and developed into fluid pieces of art which integrated words, music, and dance into cohesive storytelling entities. This deviation from tradition resulted in a body of work that was of such high quality that it continues in the present day to hold a distinct place in the history of American theatre as being innovative and entertaining. These innovations were most effectively portrayed when they were related to a strong book, as integration could not occur convincingly without a developed storyline. For some time, musical composers, like opera composers, had looked to other sources for inspiration. Whether it be from books, plays, short stories, or myths, adaptations were the norm of the theatre. But what challenges did composers face when adapting from a piece of literature? Was it necessary for the audience to be familiar with or at least aware of the literary source, or should the show stand on its own merit? Examined here are the adaptation into musicals of plays - specifically Green Grow the Lilacs into Oklahoma! and Pygmalion into My Fair Lady - and short stories - particularly "The Idyll of Miss Sarah Brown" into Guys and Dolls and Tales of the South Pacific into South Pacific. Addressed are the problems encountered by the composers/librettists during the adaptation process, specifically in choosing what elements of the source to emphasise or eliminate, and thus the general sweetening that occurred. Also discussed are the deepening of dramatic situations through music/song/dance and how this affected characterisation. Finally, the continued influence of these musicals on later generations of musical theatre composers is examined with passing comparisons given to contemporary examples.

description: This work proposes a fully decentralized strategy for maintaining the formation rigidity of a multi-robot system using only range measurements, while still allowing the graph topology to change freely over time. In this direction, a first contribution of this work is an extension of rigidity theory to weighted frameworks and the rigidity eigenvalue, which when positive ensures the infinitesimal rigidity of the framework. We then propose a distributed algorithm for estimating a common relative position reference frame amongst a team of robots with only range measurements in addition to one agent endowed with the capability of measuring the bearing to two other agents. This first estimation step is embedded into a subsequent distributed algorithm for estimating the rigidity eigenvalue associated with the weighted framework. The estimate of the rigidity eigenvalue is finally used to generate a local control action for each agent that both maintains the rigidity property and enforces additional con- straints such as collision avoidance and sensing/communication range limits and occlusions. As an additional feature of our approach, the communication and sensing links among the robots are also left free to change over time while preserving rigidity of the whole framework. The proposed scheme is then experimentally validated with a robotic testbed consisting of 6 quadrotor UAVs operating in a cluttered environment.

Critical Investigation on the IFRS Reporting Requirements of Cryptocurrencies
Creators: name: Zaheda Daruwala
Publisher: name: Zenodo
Year: 2024

description: In this paper, the author investigates the accounting treatment for cryptocurrencies under the current International Financial Reporting Standards (IFRS) guidelines. The cryptocurrency market is rapidly growing in types and numbers, along with the different avenues of application due to technological advancements. A growing number of companies are using cryptocurrencies to accept payments and other operational transactions and for investment purposes. It becomes even more critical to have appropriate accounting guidelines for recognizing and valuing these unique and risky crypto assets, as they may mislead users when assessing the company’s asset values, profitability, and liquidity aspects. This study is a two-stage exploratory study that adds to the literature on accounting for cryptocurrencies. The first stage is an exploratory study of the current accounting standards under the IFRS framework and its application to the accounting of cryptocurrencies by entities holding them. The second stage of the study performs a critical investigation of the IFRS accounting models through secondary data sources, including academic literature, reports and analyses by professional accounting organizations, criticisms by high-stakes corporations, and comment letters to the IFRS agenda decision 2019 for evaluating the existing IFRS reporting guidelines. The study examines the problems with each reporting model to identify the challenges to the fundamental quality of faithful representation of financial reporting. The need to account for and report these cryptocurrencies appropriately is increasing by the day. Currently, no specific accounting standard pertaining to the accounting treatment of cryptocurrencies exists, allowing businesses to apply various existing standards using their judgment in each case. The study recommends a unified approach to accounting for this technological and financial innovation quickly grasping global markets. This study is timely and relevant as it examines the implications of the reporting of cryptocurrencies under the current accounting framework and argues in favor of the need to establish accounting standards pertinent to the unique characteristics of cryptocurrencies for effective reporting outcomes, thereby providing confidence to businesses, investors and the capital markets.
Quantum graphs whose spectra mimic the zeros of the Riemann zeta function

description: One of the most famous problems in mathematics is the Riemann hypothesis: that the non-trivial zeros of the Riemann zeta function lie on a line in the complex plane. One way to prove the hypothesis would be to identify the zeros as eigenvalues of a Hermitian operator, many of whose properties can be derived through the analogy to quantum chaos. Using this, we construct a set of quantum graphs that have the same oscillating part of the density of states as the Riemann zeros, offering an explanation of the overall minus sign. The smooth part is completely different, and hence also the spectrum, but the graphs pick out the low-lying zeros.

description: We study isolated quantum systems with two-body interactions after a quench. In these systems, the energy shell is a Gaussian of width $σ$, and it gives the maximum possible spreading of the energy distribution of the initial states. When the distribution achieves this shape, the fidelity decay can be Gaussian until saturation. This establishes a lower bound for the fidelity decay in realistic systems. An ultimate bound for systems with many-body interactions is also derived based on the analysis of full random matrices. We find excellent agreement between numerical and analytical results. We also provide the conditions under which the short-time dynamics of few-body observables is controlled by $σ$. The analyses are developed for systems, initial states, and observables accessible to experiments.

A census of transient orbital resonances encountered during binary inspiral

description: Transient orbital resonances have recently been identified as potentially important to the inspiral of small bodies into large black holes. These resonances occur as the inspiral evolves through moments in which two fundamental orbital frequencies, $Ω_θ$ and $Ω_r$, are in a small integer ratio to one another. Previous work has demonstrated that a binary's parameters are "kicked" each time the inspiral passes through a resonance, changing the orbit's characteristics relative to a model that neglects resonant effects. In this paper, we use exact Kerr geodesics coupled to an accurate but approximate model of inspiral to survey orbital parameter space and estimate how commonly one encounters long-lived orbital resonances. We find that the most important resonances last for a few hundred orbital cycles at mass ratio $10^{-6}$, and that resonances are almost certain to occur during the time that a large mass ratio binary would be a target of gravitational-wave observations. Resonances appear to be ubiquitous in large mass ratio inspiral, and to last long enough that they are likely to affect binary evolution in observationally important ways.

description: As climate change progresses, urban areas are increasingly affected by water scarcity and the urban heat island effect. Evapotranspiration (ET) is a crucial component of urban greening initiatives of cities worldwide aimed at mitigating these issues. However, ET estimation methods in urban areas have so far been limited. An expanding number of flux towers in urban environments provide the opportunity to directly measure ET by the eddy covariance method. In this study, we present a novel approach to model urban ET by combining flux footprint modeling, remote sensing and geographic information system (GIS) data, and deep learning and machine learning techniques. This approach facilitates spatio-temporal extrapolation of ET at a half-hourly resolution; we tested this approach with a two-year dataset from two flux towers in Berlin, Germany. The benefit of integrating remote sensing and GIS data into models was investigated by testing four predictor scenarios. Two algorithms (1D convolutional neural networks (CNNs) and random forest (RF)) were compared. The best-performing models were then used to model ET values for the year 2019. The inclusion of GIS data extracted using flux footprints enhanced the predictive accuracy of models, particularly when meteorological data was more limited. The best-performing scenario (meteorological and GIS data) showed an RMSE of 0.0239 mm/h and R2 of 0.840 with RF and an RMSE of 0.0250 mm/h and a R2 of 0.824 with 1D CNN for the more vegetated site. The 2019 ET sum was substantially higher at the site surrounded by more urban greenery (366 mm) than at the inner-city site (223 mm), demonstrating the substantial influence of vegetation on the urban water cycle. The proposed method is highly promising for modeling ET in a heterogeneous urban environment and can support climate change mitigation initiatives of urban areas worldwide.

The results show that the decay width of $Z(3930)\to J/ψω$ is at least one order smaller than that of $X(3915)\to J/ψω$.

description: We give a unified division algebraic description of (D=3, N=1,2,4,8), (D=4, N=1,2,4), (D=6, N=1,2) and (D=10, N=1) super Yang-Mills theories. A given (D=n+2, N) theory is completely specified by selecting a pair (A_n, A_{nN}) of division algebras, A_n, A_{nN} = R, C, H, O, where the subscripts denote the dimension of the algebras. We present a master Lagrangian, defined over A_{nN}-valued fields, which encapsulates all cases. Each possibility is obtained from the unique (O, O) (D=10, N=1) theory by a combination of Cayley-Dickson halving, which amounts to dimensional reduction, and removing points, lines and quadrangles of the Fano plane, which amounts to consistent truncation. The so-called triality algebras associated with the division algebras allow for a novel formula for the overall (spacetime plus internal) symmetries of the on-shell degrees of freedom of the theories. We use imaginary A_{nN}-valued auxiliary fields to close the non-maximal supersymmetry algebra off-shell. The failure to close for maximally supersymmetric theories is attributed directly to the non-associativity of the octonions.

description: Citrus pectin is commonly used as a gelling agent and viscosity enhancer in food products. However, it is considered to be less effective in terms of emulsifier. This thesis explores ways to enhance the emulsifying properties of citrus pectin by molecular modification and by a proper choice of recipe parameters. It is shown how stable emulsions can be produced with citrus pectin when the viscosity enhancing effects are properly accounted for.

A model study on atom-atom interactions with large scattering length in quasi-two dimensional traps

description: We carry out a model study on two-atom interactions and bound states in quasi-two dimensional traps. The interactions are modeled by two-parameter potentials with parameters being the range $r_0$ and the $s$-wave scattering length $a_s$. We show that one can make use of two forms of finite-range model potentials, one for $a_s > 0$ and the other for $a_s < 0$. Both potentials reduce to same form in the limits $a_s \rightarrow \pm \infty $. We investigate into the dependence of the binding energies and the wave functions of two-atom trap-bound states on $a_s$ and $r_0$. In particular, we study the effects of $a_s$ ranging from large negative to large positive values on the bound state properties. Our results show that long-range interactions with infinite scattering length significantly alter the ground-state energy of the two atoms in a quasi-two or two dimensional trap. In contrast, short-range interactions can not significantly change the ground-state energy of two atoms in a 2D harmonic trap.

description: In this paper, we study rare decays $B_c\rightarrow D^{(*)}_{s,d}l\bar{l}$ within the Standard Model. The penguin, box, annihilation, color-favored cascade and color-suppressed cascade contributions are included. Based on our calculation, the annihilation and color-favored cascade diagrams play important roles in the differential branching fractions, forward-backward asymmetries, longitudinal polarizations of the final vector mesons and leptonic longitudinal polarization asymmetries. More importantly, color-favored cascade decays largely enhance the resonance cascade contributions. To avoid the resonance cascade contribution pollution, new cutting regions are put forward.

description: We present time-of-flight inelastic neutron scattering measurements at low temperature on powder samples of the magnetic pyrochlore oxides Tb2Ti2O7 and Tb2Sn2O7. These two materials possess related, but different ground states, with Tb2Sn2O7 displaying "soft" spin ice order below Tn~0.87 K, while Tb2Ti2O7 enters a hybrid, glassy spin ice state below Tg~0.2 K. Our neutron measurements, performed at T=1.5 K and 30 K, probe the crystal field states associated with the J=6 states of Tb3+ within the appropriate Fd\bar{3}m pyrochlore environment. These crystal field states determine the size and anisotropy of the Tb3+ magnetic moment in each material's ground state, information that is an essential starting point for any description of the low-temperature phase behavior and spin dynamics in Tb2Ti2O7 and Tb2Sn2O7. While these two materials have much in common, the cubic stanate lattice is expanded compared to the cubic titanate lattice. As our measurements show, this translates into a factor of ~2 increase in the crystal field bandwidth of the 2J+1=13 states in Tb2Ti2O7 compared with Tb2Sn2O7. Our results are consistent with previous measurements on crystal field states in Tb2Sn2O7, wherein the ground state doublet corresponds primarily to m_J=|\pm 5> and the first excited state doublet to mJ=|\pm 4>. In contrast, our results on Tb2Ti2O7 differ markedly from earlier studies, showing that the ground state doublet corresponds to a significant mixture of mJ=|\pm 5>, |\mp 4>, and |\pm 2>, while the first excited state doublet corresponds to a mixture of mJ=|\pm 4>, |\mp 5>, and |\pm 1>. We discuss these results in the context of proposed mechanisms for the failure of Tb2Ti2O7 to develop conventional long-range order down to 50 mK.

Higgs phenomenology in the Stealth Doublet Model

description: We analyze a model for the Higgs sector with two scalar doublets and a $Z_2$ symmetry that is manifest in the Yukawa sector but broken in the potential. Thus, one of the doublets breaks the electroweak symmetry and has tree-level Yukawa couplings to fermions, whereas the other doublet has no vacuum expectation value and no tree-level couplings to fermions. Since the $Z_2$ parity is broken the two doublets can mix, which leads to a distinct and novel phenomenology. This Stealth Doublet Model can be seen as a generalization of the Inert Doublet Model with a broken $Z_2$ symmetry. We outline the model and present constraints from theory, electroweak precision tests and collider searches, including the recent observation of a Higgs boson at the LHC. The charged scalar $H^\pm$ and the CP-odd scalar $A$ couple to fermions at one-loop level. We compute the decays of $H^\pm$ and $A$ and in particular the one-loop decays $A \to f \bar{f}$, $H^\pm \to f \bar{f}^\prime $, $H^\pm \to W^\pm Z $ and $H^\pm \to W^\pm γ$. We also describe how to calculate and renormalize such processes in our model. We find that if one of $H^\pm$ or $A$ is the lightest scalar, $H^\pm \to W^\pm γ$ or $ A \to b \bar{b} $ are typically their respective dominating decay channels. Otherwise, the dominating decays of $H^\pm$ and $A$ are into a scalar and a vector. Due to the absence of tree-level fermion couplings for $H^\pm$ and $A$, we consider pair production and associated production with vector bosons and scalars at the LHC. If the parameter space of the model that favors $H^\pm \to W^\pm γ$ is realized in Nature, we estimate that there could be a considerable amount of such events in the present LHC data.
