description: The main focus of this thesis is the study of sensory systems in the context of changing body-size. In particular the study of ant sensory systems and how these are shaped by miniaturisation. The study of insect visual ecology and physiology is used as a basis to develop a framework for the study of ant antennal sensilla and chemosensation, to interpret anatomical variation from a functional and organ design perspective. This thesis reviews the anatomy and nomenclature of antennal sensilla through two case studies on an extremely large species Myrmecia pyriformis and a small species Temnothorax rugatulus. These two studies additionally quantify intraspecific variation and discuss the potential functional consequences of this variation for self-organising insect societies and task allocation. A large scale comparative study takes the tools developed in previous chapters to focus in on how chemosensilla vary in their numbers, size and distribution through the Fomicid phylogeny. The gross anatomy of the antenna and changes in shape from club to filiform antennae are described in detail. Anatomical data are analysed to identify scaling trends and potential adaptations driven by miniaturisation. Ecological and phylogenetic considerations are discussed wherever relevant. The wide ranging impacts of body size changes are reviewed, incorporated into the interpretation of results and used to propose promising avenues for future research. Finally, ant body size and some of the different methods used in the literature to measure size and size variability are critically analysed. The functional implications of body size variability within species are discussed using Iridomyrmex purpureus as an example. This thesis makes use of a variety of microscopy techniques. In addition to the methods sections of each chapter a dedicated methods chapter is included. This chapter reviews some of the techniques used in the main data chapters and in the additional publications produced over the course of this thesis.

description: The 1923 tour of Australia by a Chinese soccer team generated considerable public attention. It was, and was intended to be, a series of events that places these athletes in contrast to prevailing stereotypes of the Chinese in Australia. Much more than a spectacle or curiosity, however, the tour provided an opportunity for a range of interests to advance their claims and to find, in relation to each other, new points of synthesis on the issues of race, class, immigration, trade and the place of the Australian nation in a post World War One context. This thesis offers an account of the tour and an analysis of the aspirations invested in it by its promoters, the press, businessmen, politicians, Chinese communities and spectators. The tour's impact is hard to assess, but its significance in reflecting this synthesis and these aspirations is considerable.
Isotropic cosmologies in Weyl geometry

description: We study homogeneous and isotropic cosmologies in a Weyl spacetime. We show that for homogeneous and isotropic spacetimes, the field equations can be reduced to the Einstein equations with a two-fluid source. We write the equations as a two-dimensional dynamical system and analyze the qualitative, asymptotic behavior of the models. We examine the possibility that in certain theories the Weyl 1-form may give rise to a late accelerated expansion of the Universe and conclude that such behaviour is not met as a generic feature of the simplest cosmologies.

description: The dynamics of a metastable attractive Bose-Einstein condensate trapped by a system of laser beams is analyzed in the presence of small fluctuations of the laser intensity. It is shown that the condensate will eventually collapse. The expected collapse time is inversely proportional to the integrated covariance of the time autocorrelation function of the laser intensity and it decays logarithmically with the number of atoms. Numerical simulations of the stochastic 3D Gross-Pitaevskii equation confirms analytical predictions for small and moderate values of mean field interaction.

description: We address the problem of differences between longitudinal and transverse velocity increments in isotropic small scale turbulence. The relationship of these two quantities is analyzed experimentally by means of stochastic Markovian processes leading to a phenomenological Fokker- Planck equation from which a generalization of the Karman equation is derived. From these results, a simple relationship between longitudinal and transverse structure functions is found which explains the difference in the scaling properties of these two structure functions.

description: Scheduling algorithms have a significant impact on the optimal utilization of HPC facilities, yet the vast majority of the research in this area is done using simulations. In working with simulations, a great deal of factors that affect a real scheduler, such as its scheduling processing time, communication latencies and the scheduler intrinsic implementation complexity are not considered. As a result, despite theoretical improvements reported in several articles, practically no new algorithms proposed have been implemented in real schedulers, with HPC facilities still using the basic first-come-first-served (FCFS) with Backfill policy scheduling algorithm. A better approach could be, therefore, the use of real schedulers in an emulation environment to evaluate new algorithms. This thesis investigates two related challenges in emulations: computational cost and faithfulness of the results to real scheduling environments. It finds that the sampling, shrinking and shuffling of a trace must be done carefully to keep the classical metrics invariant or linear variant in relation to size and times of the original workload. This is accomplished by the careful control of the submission period and the consideration of drifts in the submission period and trace duration. This methodology can help researchers to better evaluate their scheduling algorithms and help HPC administrators to optimize the parameters of production schedulers. In order to assess the proposed methodology, we evaluated both the FCFS with Backfill and Suspend/Resume scheduling algorithms. The results strongly suggest that Suspend/Resume leads to a better utilization of a supercomputer when high priorities are given to big jobs.

description: Honeypot is a decoy computer system that is used to attract and monitor hackers' activities in the network. The honeypot aims to collect information from the hackers in order to create a more secure system. However, the log file generated by honeypot can grow very large when heavy traffic occurred in the system, such as Distributed Denial of Services' (DDoS) attack. The DDoS possesses difficulty when it is being processed and analyzed by the network administrator as it required a lot of time and resources. Therefore, in this paper, we propose an approach to decrease the log size that is by using a Cron job that will run with a Perl-script. This approach parses the collected data into the database periodically to decrease the log size. Three DDoS attack cases were conducted in this study to show the increasing of the log size by sending a different amount of packet per second for 8 hours in each case. The results have shown that by utilizing the Cron job with Perl-script, the log size has been significantly reduced, the disk space used in the system has also decreased. Consequently, this approach capable of speeding up the process of parsing the log file into the database and thus, improving the overall system performance. This study contributes to providing a pathway in reducing honeypot log storage using the Cron job with Perl-Script.

description: We consider the spin-glass phase of the Sherrington-Kirkpatrick model in the presence of a magnetic field. The series expansion of the Parisi function $q(x)$ is computed at high orders in powers of $τ=T_c-T$ and $H$. We find that none of the Parisi-Toulouse scaling hypotheses on the $q(x)$ behavior strictly holds, although some of them are violated only at high orders. The series is resummed yielding results in the whole spin-glass phase which are compared with those from a numerical evaluation of the $q(x)$. At the high order considered, the transition turns out to be third order on the Almeida-Thouless line, a result which is confirmed rigorously computing the expansion of the solution near the line at finite $τ$. The transition becomes smoother for infinitesimally small field while it is third order at strictly zero field.

description: We formulate a full quantum mechanical theory of the interaction between electromagnetic modes in photonic crystal slabs and quantum well excitons embedded in the photonic structure. We apply the formalism to a high index dielectric layer with a periodic patterning suspended in air. The strong coupling between electromagnetic modes lying above the cladding light line and exciton center of mass eigenfunctions manifests itself with the typical anticrossing behavior. The resulting band dispersion corresponds to the quasi-particles coming from the mixing of electromagnetic and material excitations, which we call photonic crystal polaritons. We compare the results obtained by using the quantum theory to variable angle reflectance spectra coming from a scattering matrix approach, and we find very good quantitative agreement.

description: We compute the far-from-equilibrium dynamics of relativistic scalar quantum fields in 3+1 space-time dimensions starting from over-occupied initial conditions. We determine universal scaling exponents and functions for two-point correlators and the four-vertex in a self-similar regime in time and space or momenta. The scaling form of the momentum-dependent four-vertex exhibits a dramatic fall-off towards low momenta. Comparing spectral functions (commutators) and statistical correlations (anti-commutators) of field operators allows us to detect strong violations of the fluctuation-dissipation relation in this non-perturbative infrared regime. Based on a self-consistent expansion in the number of field components to next-to-leading order, a wide range of interaction strengths is analyzed and compared to weak-coupling estimates in effective kinetic theory and classical-statistical field theory.

description: Negative refraction usually demands complex structure engineering while it is very natural for massless Dirac fermions (MDFs) across the \textit{p-n} junction, this leads to Dirac electron optics. The emergent Dirac materials may exhibit hitherto unidentified phenomenon due to their nontrivial band structures in contrast to the isotropic MDFs in graphene. Here, as a specific example, we explore the negative refraction induced caustics and Veselago focusing of tilted MDFs across 8-\textit{Pmmn} borophene \textit{p-n} junctions. To this aim, we develop a technique to effectively construct the electronic Green's function in \textit{p-n} junctions with arbitrary junction directions. Based on analytical discussions and numerical calculations, we demonstrate the strong dependence of interference pattern on the junction direction. As the junction direction perpendicular to the tilt direction, Veselago focusing or normal caustics (similar to that in graphene) appears resting on the doping configuration of the \textit{p-n} junctions, otherwise anomalous caustics (different from that in graphene) occurs which is manipulated by the junction direction and the doping configuration. Finally, the developed Green's function technique is generally promising to uncover the unique transport of emergent MDFs, and the discovered anomalous caustics makes tilted MDFs potential applications in Dirac electron optics.

description: Silicon tracking detectors provide excellent spatial resolution, and so can provide excellent momentum resolution for energetic charged particles, even in compact detectors. However, at lower momenta, multiple scattering in the silicon degrades the momentum resolution. We present an alternate method to measure momentum and alleviate this degradation, using silicon detectors that also incorporate timing measurements. By using timing information between two silicon layers, it is possible to solve for the the radius of curvature, and hence the particle momentum, independent of multiple scattering within the silicon. We consider three examples: an all-silicon central tracker for an electron-ion collider, a simplified version of the CMS detector, and a forward detector for an electron-ion collider. For a 75 cm diameter tracker in a 1.5 T magnetic field, timing can improve the momentum determination for particles with momentum below 500 MeV/c. In the 3.8 T CMS magnetic field and 1.2 m radius tracker, timing can improve tracking up to momenta of 1.3 GeV/c. The resolution is best at mid-rapidity. We also discuss a simpler system, consisting of a single timing detector outside an all-silicon tracker.

description: This paper deals with the heating and the ionization of the interstellar medium (ISM) in the 500 central pc of the Milky Way (hereafter Galactic center, GC). We review the results of the Infrared Space Observatory (ISO) observations of a sample of GC molecular clouds located far from thermal radiocontinuum or far-infrared sources. For the first time, we have been able to study in detail the dust continuum spectra from 40 to 190 microns founding a warm (30-40 K) dust component in addition to the well known 15-20 K component. Fine-structure lines observations have revealed the presence of diffuse ionized gas associated with the molecular clouds. The effective temperature of the ionizing radiation is higher than 33000 K. ISO has also allow us to measure the fraction of warm (~ 150 K) H2 in the GC clouds, which is on average of 30 %. The observations of the warm (a few 100 K) neutral gas are compatible with a Photon Dominated Region (PDR) scenario.

description: The Hall-Vinen-Bekharevich-Khalatnikov (HVBK) equations are a macroscopic model of superfluidity at non-zero temperatures. For smooth, compactly supported data, we prove the global well-posedness of strong solutions to these equations in $\mathbb{R}^2$, in the incompressible and isothermal case. The proof utilises a contraction mapping argument to establish local well-posedness for high-regularity data, following which we demonstrate global regularity using an analogue of the Beale-Kato-Majda criterion in this context. In the appendix, we address the sufficient conditions on a 2D vorticity field, in order to have a finite kinetic energy.

The orbital modulation at 79.71\pm0.01 min is double humped; the superhump period is 81.702\pm0.007 min. Towards the end of the outburst late superhumps with a period of 81.29\pm0.01 min were observed. We argue that this is a system of very low mass transfer rate, and that it probably has a long outburst interval.

description: Anti-patterns are poor solutions to recurring design problems. Number of empirical studies have highlighted the negative impact of anti-patterns on software maintenance which motivated the development of various detection techniques. Most of these approaches rely on structural metrics of software systems to identify affected components while others exploit historical information by analyzing co-changes occurring between code components. By relying solely on one aspect of software systems (i.e., structural or historical), existing approaches miss some precious information which limits their performances. In this paper, we propose CAME (Convolutional Analysis of code Metrics Evolution), a deep-learning based approach that relies on both structural and historical information to detect anti-patterns. Our approach exploits historical values of structural code metrics mined from version control systems and uses a Convolutional Neural Network classifier to infer the presence of anti-patterns from this information. We experiment our approach for the widely known God Class anti-pattern and evaluate its performances on three software systems. With the results of our study, we show that: (1) using historical values of source code metrics allows to increase the precision; (2) CAME outperforms existing static machine-learning classifiers; and (3) CAME outperforms existing detection tools.

Ambipolar Diffusion in the Magnetorotational Instability

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The effects of ambipolar diffusion on the linear stability of weakly ionised accretion discs are examined. Earlier work on this topic has focused on axial magnetic fields and perturbation wavenumbers. We consider here more general field and wavenumber geometries, and find that qualitatively new results are obtained. Provided a radial wavenumber and azimuthal field are present along with their axial counterparts, ambipolar diffusion will always be destabilising, with unstable local modes appearing at well-defined wavenumber bands. The wavenumber corresponding to the maximum growth rate need not, in general, lie along the vertical axis. Growth rates become small relative to the local angular velocity when the ion-neutral collision time exceeds the orbital time. In common with Hall electromotive forces, ambipolar diffusion destabilises both positive and negative angular velocity gradients. In at least some cases, therefore, uniformly rotating molecular cloud cores may reflect the marginally stable state of the ambipolar magnetorotational instability.

description: Software systems emerge from mere keystrokes to form intricate functional networks connecting many collaborating modules, objects, classes, methods, and subroutines. Building on recent advances in the study of complex networks, I have examined software collaboration graphs contained within several open-source software systems, and have found them to reveal scale-free, small-world networks similar to those identified in other technological, sociological, and biological systems. I present several measures of these network topologies, and discuss their relationship to software engineering practices. I also present a simple model of software system evolution based on refactoring processes which captures some of the salient features of the observed systems. Some implications of object-oriented design for questions about network robustness, evolvability, degeneracy, and organization are discussed in the wake of these findings.

description: As high-dimensional and high-frequency data are being collected on a large scale, the development of new statistical models is being pushed forward. Functional data analysis provides the required statistical methods to deal with large-scale and complex data by assuming that data are continuous functions, e.g., a realization of a continuous process (curves) or continuous random fields (surfaces), and that each curve or surface is considered as a single observation. Here, we provide an overview of functional data analysis when data are complex and spatially correlated. We provide definitions and estimators of the first and second moments of the corresponding functional random variable. We present two main approaches: The first assumes that data are realizations of a functional random field, i.e., each observation is a curve with a spatial component. We call them 'spatial functional data'. The second approach assumes that data are continuous deterministic fields observed over time. In this case, one observation is a surface or manifold, and we call them 'surface time series'. For the two approaches, we describe software available for the statistical analysis. We also present a data illustration, using a high-resolution wind speed simulated dataset, as an example of the two approaches. The functional data approach offers a new paradigm of data analysis, where the continuous processes or random fields are considered as a single entity. We consider this approach to be very valuable in the context of big data.

description: We develop a microscopic theory of single-electron transport in N-S-N hybrid structures in the presence of applied magnetic field introducing vortex lines in a superconductor layer. We show that vortex cores in a thick and clean superconducting layer are similar to mesoscopic conducting channels where the bound core states play the role of transverse modes. The transport through not very thick layers is governed by another mechanism, namely by resonance tunneling via vortex core levels. We apply our method to calculation of the thermal conductance along the magnetic field.

description: To describe objective social disconnectedness and perceived social isolation post-spinal cord injury/dysfunction (SCI/D), and to examine associations among social disconnectedness and social isolation by sociodemographic and clinical characteristics. A telephone-based questionnaire was administered to 170 community dwelling individuals with a SCI/D. Social disconnectedness was measured by social network size, composition, and frequency of contact. Social isolation was measured using the revised three item UCLA Loneliness Scale. Of the 170 participants, the majority were men (n = 136, 80%), had a traumatic injury (n = 149, 87.6%), and had incomplete tetraplegia (n = 58, 34%). The mean network size was 3.86 (SD = 2.0) of a maximum seven. The mean loneliness score for the sample was 4.93 (SD = 1.87). Factors associated with lower feelings of loneliness included being married, living with a higher proportion of network members, and being employed. Size of networks was not significantly associated with feelings of loneliness. This study highlights the vulnerability for perceived social isolation among persons with SCI/D. The size of network does not seem to matter as much as the frequency and quality of social interactions. Findings reinforce the complexity of social disconnectedness and the importance in understanding the various indicators of social disconnectedness as they relate to social isolation.IMPLICATIONS FOR REHABILITATIONSocial relationships have been shown to be a vital component of optimal health and well-being.Individuals with a spinal cord injury/dysfunction are faced with a number of challenges in developing and maintaining social relationships and community participation.Rehabilitation professionals should encourage opportunities for social inclusion, employment and community participation to optimize health and well-being for this population.

Abstract Voxelotor (Oxbryta™) is a haemoglobin S polymerization inhibitor that has been developed for the treatment of sickle cell disease. In November 2019, voxelotor received its first global approval in the USA for the treatment of sickle cell disease in adults and paediatric patients aged ≥ 12 years. The drug was granted accelerated approval based on the results of the phase III HOPE trial. Phase III clinical development of voxelotor for sickle cell disease is ongoing worldwide. Voxelotor also has Orphan Drug designation and Priority Medicine status in Europe for the treatment of sickle cell disease. This article summarizes the milestones in the development of voxelotor leading to this first approval for sickle cell disease.

description: Synchrotron Laue microdiffraction and Digital Image Correlation measurements were coupled to track the elastic strain field (or stress field) and the total strain field near a general grain boundary in a bent bicrystal. A 316L stainless steel bicrystal was deformed in situ into the elasto-plastic regime with a four-point bending setup. The test was then simulated using finite elements with a crystal plasticity model comprising internal variables (dislocation densities on discrete slip systems). The predictions of the model have been compared with both the total strain field and the elastic strain field obtained experimentally. While activated slip systems and total strains are reasonably well predicted, elastic strains appear overestimated next to the grain boundary. This suggests that conventional crystal plasticity models need improvement to correctly model stresses at grain boundaries.

description: In this paper we model the tomography of scale free networks by studying the structure of layers around an arbitrary network node. We find, both analytically and empirically, that the distance distribution of all nodes from a specific network node consists of two regimes. The first is characterized by rapid growth, and the second decays exponentially. We also show that the nodes degree distribution at each layer is a power law with an exponential cut-off. We obtain similar results for the layers surrounding the root of multicast trees cut from such networks, as well as the Internet. All of our results were obtained both analytically and on empirical Interenet data.
Nonlinear optics of surface plasmon toy black holes

description: Nonlinear optical behavior of recently introduced surface plasmon toy black hole models has been considered. Physical realization of these models involves droplets of liquid on a metal surface, which supports propagation of surface plasmons. Such droplets are shown to exhibit strongly enhanced nonlinear optical behavior in the frequency range near the surface plasmon resonance of a metal-liquid interface. This enhancement may be responsible for the missing orders of magnitude of field enhancement in the surface enhanced Raman scattering effect. In addition, experimental observation of the recently predicted optical second harmonic generation near the toy event horizon is reported. Finally, the possibility of toy Hawking radiation observation is discussed, and the expression for the effective Hawking temperature of a toy surface plasmon black hole is derived. The effective Hawking temperature appears to be in the range of a few hundreds Kelvin for the realistic droplet shapes, which may lead to a surprising conclusion that the shapes of the liquid droplets on metal substrates are to some degree determined by the Hawking radiation.

description: The microscopic mechanism of the melting of a crystal is analyzed by the constant pressure Monte Carlo simulation of a Lennard-Jones fcc system. Beyond a temperature of the order of 0.8 of the melting temperature, we found that the relevant excitations are lines of defects. Each of these lines has the structure of a random walk of various lengths on an fcc defect lattice. We identify these lines with the dislocation ones proposed in recent phenomenological theories of melting. Near melting we find the appearance of long lines that cross the whole system. We suggest that these long lines are the precursor of the melting process.

description: The body of literature on underrepresentation and gender inequality is vast. However, despite its potential to perpetuate gender stereotypes, the overrepresentation of women in media has received inadequate attention. This study explores how traditional news media and social media overrepresent females as drivers when discussing traffic accidents, and whether social media could be the ‘new equalizer’ for gender. Focusing on China, we collected 97,120 posts from Weibo, China’s largest microblogging site, and 11,290 newspaper articles dated between January 2010 and November 2018. We analyzed the data through a mixed-methods design and found that female drivers are overrepresented in discussions of traffic accidents, in both newspapers and on Weibo. While the gender bias against female drivers is more prevalent on Weibo than in newspapers, Weibo has provided a platform for gender-aware discussion. Our study closes by offering suggestions for cross-platform and cross-cultural comparisons of gender representation in the digital age.

description: We consider a homogeneous 1D Bose gas with contact interactions and large attractive coupling constant. This system can be realized in tight waveguides by exploiting a confinement induced resonance of the effective 1D scattering amplitude. By using a variational {\it ansatz} for the many-body wavefunction, we show that for small densities the gas-like state is stable and the corresponding equation of state is well described by a gas of hard rods. By calculating the compressibility of the system, we provide an estimate of the critical density at which the gas-like state becomes unstable against cluster formation. Within the hard-rod model we calculate the one-body density matrix and the static structure factor of the gas. The results show that in this regime the system is more strongly correlated than a Tonks-Girardeau gas. The frequency of the lowest breathing mode for harmonically trapped systems is also discussed as a function of the interaction strength.
