description: We study polar quasinormal modes of relativistic stars in scalar-tensor theories, where we include a massive gravitational scalar field and employ the standard Brans-Dicke coupling function. For the potential of the scalar field we consider a simple mass term as well as a potential associated with $R^2$ gravity. The presence of the scalar field makes the spectrum of quasinormal modes much richer than the spectrum in General Relativity. We here investigate radial modes ($l=0$) and quadrupole modes ($l=2$). The general relativistic $l=0$ normal modes turn into quasinormal modes in scalar-tensor theories, that are able to propagate outside of the stars. In addition to the pressure-led modes new scalar-led $ϕ$-modes arise. We analyze the dependence of the quasinormal mode frequencies and decay times on the scalar field mass.

description: We study the competition between interactions and disorder in two dimensions. Whereas a noninteracting system is always Anderson localized by disorder in two dimensions, a pure system can develop a Mott gap for sufficiently strong interactions. Within a simple model, with short-ranged repulsive interactions, we show that, even in the limit of strong interaction, the Mott gap is completely washed out by disorder for an infinite system for dimensions $D\le 2$. The probability of a nonzero gap falls onto a universal curve, leading to a glassy state for which we provide a scaling function for the frequency dependent susceptibility.

description: The Boltzmann equation for inelastic Maxwell models is considered to determine the velocity moments through fourth degree in the simple shear flow state. First, the rheological properties (which are related to the second-degree velocity moments) are {\em exactly} evaluated in terms of the coefficient of restitution $α$ and the (reduced) shear rate $a^*$. For a given value of $α$, the above transport properties decrease with increasing shear rate. Moreover, as expected, the third-degree and the asymmetric fourth-degree moments vanish in the long time limit when they are scaled with the thermal speed. On the other hand, as in the case of elastic collisions, our results show that, for a given value of $α$, the scaled symmetric fourth-degree moments diverge in time for shear rates larger than a certain critical value $a_c^*(α)$ which decreases with increasing dissipation. The explicit shear-rate dependence of the fourth-degree moments below this critical value is also obtained.

description: The $ϕ(\kpp)\sim \kpp$ relation is called polarization structure. By density functional calculations, we study the polarization structure in ferroelectric perovskite PbTiO$_3$, revealing (1) the $\kpp$ point that contributes most to the electronic polarization, (2) the magnitude of bandwidth, and (3) subtle curvature of polarization dispersion. We also investigate how polarization structure in PbTiO$_3$ is modified by compressive inplane strains. The bandwidth of polarization dispersion in PbTiO$_3$ is shown to exhibit an unusual decline, though the total polarization is enhanced. As another outcome of this study, we formulate an analytical scheme for the purpose of identifying what determine the polarization structure at arbitrary $\kpp$ points by means of Wannier functions. We find that $ϕ(\kpp)$ is determined by two competing factors: one is the overlaps between neighboring Wannier functions within the plane {\it perpendicular} to the polarization direction, and the other is the localization length {\it parallel} to the polarization direction. Inplane strain increases the former while decreases the latter, causing interesting non-monotonous effects on polarization structure. Finally, polarization dispersion in another paradigm ferroelectric BaTiO$_3$ is discussed and compared with that of PbTiO$_3$.

description: The spin asymmetry of the photon in the exclusive A(gamma,pi N)A-1 reaction is computed employing a recently developed fully relativistic model based on elementary pion production amplitudes that include a consistent treatment of the spin-3/2 nucleon resonances. We compare the results of this model to the only available data on Oxygen [Phys. Rev. C 61 (2000) 054609] and find that, contrary to other models, the predicted spin asymmetry compares well to the available experimental data in the Delta(1232) region. Our results indicate that no major medium modifications in the Delta(1232) properties are needed in order to describe the measured spin asymmetries.

A Generalized Publication Bias Model

description: Scargle (2000) has discussed Rosenthal and Rubin's (1978) "fail-safe number" (FSN) method for estimating the number of unpublished studies in meta-analysis. He concluded that this FSN cannot possibly be correct because a central assumption the authors used conflicts with the very definition of publication bias. While this point has been made by others before (Elsahoff, 1978; Darlington, 1980; Thomas, 1985, Iyengar & Greenhouse, 1988), Scargle showed, by way of a simple 2-parameter model, how far off Rosenthal & Rubin' s estimate can be in practice. However, his results relied on the assumption that the decision variable is normally distributed with zero mean. In this case the ratio of unpublished to published papers is large only in a tiny region of the parameter plane. Building on these results, we now show that (1) Replacing densities with probability masses greatly simplifies Scargle's derivations and permits an explicit statement of the relation between the probability alpha of Type I errors and the step-size beta; (2) This result does not require any distribution assumptions; (3) The distinction between 1-sided and 2-sided rejection regions becomes immaterial; (4) This distribution-free approach leads to an immediate generalization to partitions involving more than two intervals, and thus covers more general selection functions.

We prove two quaternionic versions of a well known characterization of triangularizable subalgebras of matrix algebras over an algebraically closed field. Finally we consider the problem of describing the semi-algebraic set of pairs (X,Y) of quaternionic n by n matrices which are simultaneously triangularizable. Even the case n=2, which we analyze in more detail, remains unsolved.

description: We consider the propagation of slow light with an orbital angular momentum (OAM) in a moving atomic medium. We have derived a general equation of motion and applied it in analysing propagation of slow light with an OAM in a rotating medium, such as a vortex lattice. We have shown that the OAM of slow light manifests itself in a rotation of the polarisation plane of linearly polarised light. To extract a pure rotational phase shift, we suggest to measure a difference in the angle of the polarisation plane rotation by two consecutive light beams with opposite OAM. The differential angle $Δα_{\ell}$ is proportional to the rotation frequency of the medium $ω_{\mathrm{rot}}$ and the winding number $\ell$ of light, and is inversely proportional to the group velocity of light. For slow light the angle $Δα_{\ell}$ should be large enough to be detectable. The effect can be used as a tool for measuring the rotation frequency $ω_{\mathrm{rot}}$ of the medium.

We study fluctuations of the local density of states in a superconducting state of weakly disordered films. We perform numerical computations in the framework of the disordered attractive Hubbard model on two-dimensional square lattices. Our numerical results are explained by an analytical theory. The numerical data and the theory together form a coherent picture of multifractal correlations of local density of states in weakly disordered superconducting films.

description: In earlier work, carrying out numerical simulations of the Ricci flow of families of rotationally symmetric geometries on $S3$, we have found strong support for the contention that (at least in the rotationally symmetric case) the Ricci flow for a ``critical'' initial geometry - one which is at the transition point between initial geometries (on $S^3$) whose volume-normalized Ricci flows develop a singular neck pinch, and other initial geometries whose volume normalized Ricci flows converge to a round sphere - evolves into a ``degenerate neck pinch.'' That is, we have seen in this earlier work that the Ricci flows for the critical geometries become locally cylindrical in a neighborhood of the initial pinching, and have the maximum amount of curvature at one or both of the poles. Here, we explore the behavior of these flows at the poles, and find strong support for the conjecture that the Bryant steady solitons accurately model this polar flow.

description: What are the pathways for spreading disinformation on social media platforms? This article addresses this question by collecting, categorising, and situating an extensive body of research on how application programming interfaces (APIs) provided by social media platforms facilitate the spread of disinformation. We first examine the landscape of official social media APIs, then perform quantitative research on the open-source code repositories GitHub and GitLab to understand the usage patterns of these APIs. By inspecting the code repositories, we classify developers' usage of the APIs as official and unofficial, and further develop a four-stage framework characterising pathways for spreading disinformation on social media platforms. We further highlight how the stages in the framework were activated during the 2016 US Presidential Elections, before providing policy recommendations for issues relating to access to APIs, algorithmic content, advertisements, and suggest rapid response to coordinate campaigns, development of collaborative, and participatory approaches as well as government stewardship in the regulation of social media platforms.

description: Following the detection of CO and HCN in Pluto's atmosphere, we report on new ALMA observations of Pluto with two main goals: (i) obtaining spatially-resolved measurements (~0.06'' on the ~0.15'' disk subtended by Pluto and its atmosphere) of CO(3-2) and HCN(4-3) (ii) targetting new chemical compounds, primarily hydrogen isocyanide (HNC). The CO line shows an absorption core at beam positions within Pluto's disk, a direct signature of Pluto's cold mesosphere. Analysis provides tentative evidence for a non-uniform temperature field in the lower atmosphere (near 30 km), with summer pole latitudes being 7$\pm$3.5 K warmer than low latitudes. This unexpected result may point to shorter radiative timescales in the atmosphere than previously thought. The HCN emission is considerably more extended than CO, peaking at radial distances beyond Pluto limb, and providing a new method to determine Pluto's HCN vertical profile in 2017. The mean (column-averaged) location of HCN is at 690+/-75 km altitude, with an upper atmosphere (> 800 km) mixing ratio of ~ 1.8 x 10$^{-4}$. Little or no HCN (<5 x 10$^{-9}$ at 65 km) is present in the lower atmosphere, implying undersaturation of HCN there. The HCN emission appears enhanced above the low-latitude limb, but interpretation, in terms of an enhanced HCN abundance or a warmer upper atmosphere there, is uncertain. The first detection of HNC is reported, with a (7.0$\pm$2.1) x 10$^{12}$ cm$^{-2}$ column density, referred to Pluto surface, and a HNC / HCN ratio of 0.095+/-0.026, very similar to their values in Titan's atmosphere. We also obtain upper limits on CH3CN (< 2.6 x 10$^{13}$ cm$^{-2}$) and CH$_3$CCH (< 8.5 x 10$^{14}$ cm$^{-2}$); the latter value is inconsistent with the reported detection of CH$_3$CCH from New Horizons. These upper limits also point to incomplete resublimation of ice-coated aerosols in the lower atmosphere.

Then $R$ is symmetric (respectively, reversible) if and only if $R$ is $σ$-symmetric (respectively, $σ$-reversible) if and only if $R[x;σ,δ]$ is symmetric (respectively, reversible). Moreover, we study on the relationship between the Baerness, quasi-Baerness and p.q.-Baerness of a ring $R$ and these of the Ore extension $R[x;σ,δ]$. As a consequence we obtain a partial generalization of \cite{hong/2000}.

description: Difficulties associated with the integration of liquids into a UHV environment make surface-science style studies of mineral dissolution particularly challenging. Recently, we developed a novel experimental setup for the UHV-compatible dosing of ultrapure liquid water, and studied its interaction with TiO2 and Fe3O4 surfaces. Here, we describe a simple approach to vary the pH through the partial pressure of CO2 (pCO2) in the surrounding vacuum chamber, and use this to study how these surfaces react to an acidic solution. The TiO2(110) surface is unaffected by the acidic solution, except for a small amount of carbonaceous contamination. The Fe3O4(001)-(rt2 x rt2)R45 surface begins to dissolve at a pH 4.0-3.9 (pCO2 = 0.8-1 bar) and, although it is significantly roughened, the atomic-scale structure of the Fe3O4(001) surface layer remains visible in scanning tunneling microscopy (STM) images. X-ray photoelectron spectroscopy (XPS) reveals that the surface is chemically reduced, and contains a significant accumulation of bicarbonate (HCO3-) species. These observations are consistent with Fe(II) being extracted by bicarbonate ions, leading to dissolved iron bicarbonate complexes (Fe(HCO3)2), which precipitate onto the surface when the water evaporates.

However, the possibility that species-specific defense reactions could serve as a basis for the study of anxiolytic agents had been overlooked. The results of the present investigations showed that the rat's proclivity to bury objects associated with aversive stimulation is particularly sensitive to the effects of anxiolytic agents. The defensive burying behaviour of rats was rapidly suppressed by a single injection of the anxiolytic drug, diazepam, and as the dose of diazepam was increased, the magnitude of its suppressive effect was increased. In addition, the relative potencies of the anxiolytics diazepam, chlordiazepoxide, and pentobarbital in the conditioned burying paradigm compared favorably with their relative potencies in clinical settings. Furthermore, conditioned defensive burying seemed to be selectively sensitive to the effects of anxiolytics: four nonanxiolytic compounds, picrotoxin, pentylenetetrazol, d-amphetamine, and morphine, did not reliably suppress burying. One nonanxiolytic compound, chlorpromazine, did suppress conditioned defensive burying; however, its effects could be reliably dissociated from the effects of diazepam by varying the severity of the aversive stimulus. Chlorpromazine suppressed burying at both low and high shock intensities; whereas, diazepam suppressed burying only at the low shock intensity. Thus, the conditioned defensive burying paradigm appears to fulfil the three major criteria of a valid animal test of anxiolytic agents: sensitivity, relative potency, and selectivity. In the remaining studies, the conditioned defensive burying test was used as a model to study some of the putative mechanisms of action of anxiolytic agents. The observation that diazepam suppressed the unconditioned defensive burying elicited in the absence of painful stimulation ruled out the possibility that the suppressive effect of diazepam was due to analgesic, rather than anxiolytic, action. In subsequent experiments, altering the functions of GABA ergic neurons with picrotoxin was found to have no effect on either conditioned or unconditioned defensive burying. However, picrotoxin did reverse the suppressive effect of diazepam, suggesting that the mechanism whereby diazepam exerts its effect on burying may involve an interaction between diazepam and GABA ergic neural systems. The systematic and robust nature of the present results suggests that the conditioned defensive burying paradigm could prove to be a valuable tool for screening potential anxiolytic agents and for studying their mechanisms of action.

description: We study 2D Maxwell-dilaton gravity on AdS(2). We distinguish two distinctive cases depending on whether the AdS(2) solution can be lifted to an AdS(3) geometry. In both cases, in order to get a consistent boundary condition we need to work with a twisted energy momentum tensor which has non-zero central charge. With this central charge and the explicit form of the twisted Virasoro generators we compute the entropy of the system using the Cardy formula. The entropy is found to be the same as that obtained from gravity calculations for a specific value of the level of the U(1) current. The agreement is an indication of $AdS(2)/CFT(1) correspondence.

description: This article considers how affects animate and uphold tourism and settler colonialism. Engaging a ‘curious’ postdisciplinary research methodology informed by the relational power of listening, I trace the emergence of two interrelated atmospheres in the city of Niagara Falls, Ontario, Canada, both of which exemplify how settler colonialism is built and maintained as a structure of feeling that supports larger processes of worldmaking via tourism. In detailing these two atmospheres and their effects, I illuminate the mechanisms and practices through which tourism-related atmospheric infrastructures overtly and covertly contribute to worldmaking; exemplify how settlers might learn to destabilize, disrupt, or diffuse such atmospherics in and through tourism as a practice of unsettling; and expand on the literature detailing how we might research affective, embodied, and atmospheric moments of tourism. I take inspiration from related critical, interventionist, and narrative work in tourism and build on it to suggest that unsettling tourism—or tourism worldmaking—must be oriented toward mediating agencies of worldmaking like light and sound.

description: (Abridged) Soft and hard X-ray excesses, compared to the continuum power-law shape between ~2-10 keV, are common features observed in the spectra of active galactic nuclei (AGN) and are associated with the accretion disc-corona system around the supermassive black hole. However, the dominant process at work is still highly debated and has been proposed to be either relativistic reflection or Comptonisation. We aim to characterise the main X-ray spectral physical components from the bright bare Broad Line Seyfert 1 AGN Mrk 110, and the physical process(es) at work in its disc-corona system viewed almost face-on. We perform the X-ray broad-band spectral analysis thanks to two simultaneous XMM-Newton and NuSTAR observations performed on November 16-17 2019 and April 5-6 2020, we also use for the spectral analysis above 3 keV the deep NuSTAR observation obtained in January 2017. The broad-band X-ray spectra of Mrk 110 are characterised by the presence of a prominent and absorption-free smooth soft X-ray excess, moderately broad OVII and FeKalpha emission lines and a lack of a strong Compton hump. The continuum above ~3keV is very similar at both epochs, while some variability (stronger when brighter) is present for the soft X-ray excess. A combination of soft and hard Comptonisation by a warm and hot corona, respectively, plus mildly relativistic disc reflection reproduce the broadband X-ray continuum very well. The inferred warm corona temperature, kT_warm~0.3 keV, is similar to the values found in other sub-Eddington AGN, whereas the hot corona temperature, kT_hot~21-31 keV (depending mainly on the assumed hot corona geometry), is found to be in the lower range of the values measured in AGN.

description: We consider finite Bernoulli convolutions with a parameter $1/2 < r < 1$ supported on a discrete point set, generically of size $2^N$. These sequences are uniformly distributed with respect to the infinite Bernoulli convolution measure $ν_r$, as $N$ tends to infinity. Numerical evidence suggests that for a generic $r$, the distribution of spacings between appropriately rescaled points is Poissonian. We obtain some partial results in this direction; for instance, we show that, on average, the pair correlations do not exhibit attraction or repulsion in the limit. On the other hand, for certain algebraic $r$ the behavior is totally different.

title: Multiscale modelling of cancer evolution: the role of fibres and macrophages in invasion patterns
Creators: name: Süveges, Szabolcs
Publisher: name: University of Dundee
Year: 2021

description: The ability to invade its surrounding tissue is one of the acknowledged hallmarks of cancer. This complex multi-scale process is affected by many players of the tumour microenvironment (TME), including the extracellular matrix (ECM) and various stromal cells such as macrophages. One of these key processes is the secretion of matrix degrading enzymes that enables the degradation of the neighbouring ECM and cell-matrix adhesion. By varying the strength of cell-matrix and multiple cell-cell adhesions, cancer cells can spread into the surrounding tissues which combined with an unregulated proliferation results in an uncontrollable, indefinite growth.

This thesis considers a continuous multi-scale moving boundary model for general solid tumours that takes into account the multi-scale interactions between the different cell populations and a two-phase ECM as well as the proteolytic molecular processes taking place along the leading edge of a growing solid tumour. To that end, we investigate how one of the most abundant immune cells in the TME, the macrophages, and their phenotype influence the overall tumour progression, by exploring their multi-scale effects. Moreover, we extend our approach and consider a discrete cell population consisting of individual cancer cells that allows us to further study the complex interaction between the cancer cells and a two-phase ECM as well as the overall shape and migration type of a tumour aggregation. Finally, we apply our general continuous model to a specific type of brain tumour, glioblastomas, using patient-specific brain scans that allows us to investigate the role of brain micro-fibres in a 3-dimensional invading tumour.

description: We investigate the possible existence of nonradiating motions of systems of point charges, according to classical electrodynamics with retarded potentials. We prove that two point particles of arbitrary electric charges cannot move for an infinitely long time within a finite region of space without radiating electromagnetic energy. We show however with an example that nonradiating accelerated motions of systems of point charges do in general exist.

description: We describe a scalable, high-speed, and robust architecture for measurement-based quantum-computing with trapped ions. Measurement-based architectures offer a way to speed-up operation of a quantum computer significantly by parallelizing the slow entangling operations and transferring the speed requirement to fast measurement of qubits. We show that a 3D cluster state suitable for fault-tolerant measurement-based quantum computing can be implemented on a 2D array of ion traps. We propose the projective measurement of ions via multi-photon photoionization for nanosecond operation and discuss the viability of such a scheme for Ca ions.

description: Bound states in the continuum (BIC) have been at the forefront of research in optics and photonics over the past decade. It is of great interest to study the effects associated with quasi-BICs in the simplest structures, where quasi-BICs are very pronounced. An example is a dielectric cylinder, and in a number of works, quasi-BICs have been studied both in single cylinders and in structures composed of cylinders. In this work, we studied the properties of quasi-BICs during the transition from a homogeneous dielectric cylinder in an air environment to a ring with narrow walls while increasing the diameter of the inner air cylinder gradually. The results demonstrate the quasi-BIC crossover from the strong-coupling to the weak-coupling regime, which manifests itself in the transition from avoided crossing of branches to their intersection with the quasi-BIC being preserved on only one straight branch. In the regime of strong-coupling and quasi-BIC, three waves interfere in the far-field zone: two waves corresponding to the resonant modes of the structure and the wave scattered by the structure as a whole. The validity of the Fano resonance concept is discussed, since it describes the interference of only two waves under weak coupling conditions.

description: Quantum networks are often modelled using Schroedinger operators on metric graphs. To give meaning to such models one has to know how to interpret the boundary conditions which match the wave functions at the graph vertices. In this article we give a survey, technically not too heavy, of several recent results which serve this purpose. Specifically, we consider approximations by means of ``fat graphs'' -- in other words, suitable families of shrinking manifolds -- and discuss convergence of the spectra and resonances in such a setting.

description: The purpose of this work is to survey what is known about the linear independence of spikes and sines. The paper provides new results for the case where the locations of the spikes and the frequencies of the sines are chosen at random. This problem is equivalent to studying the spectral norm of a random submatrix drawn from the discrete Fourier transform matrix. The proof involves depends on an extrapolation argument of Bourgain and Tzafriri.
