description: In this paper, we give infinitely many diffeomorphic families of different Weinstein manifolds. The diffeomorphic families consist of the Milnor fibers of $ADE$-type, and a Weinstein manifold constructed by gluing a cotangent bundle to the Milnor fiber of $A$-type. The last-mentioned members of the families have decomposable wrapped Fukaya categories.

description: This chapter is devoted to the computation of equilibrium (thermodynamic) properties of quantum systems. In particular, we will be interested in the situation where the interaction between particles is so strong that it cannot be treated as a small perturbation. For weakly coupled systems many efficient theoretical and computational techniques do exist. However, for strongly interacting systems such as nonideal gases or plasmas, strongly correlated electrons and so on, perturbation methods fail and alternative approaches are needed. Among them, an extremely successful one is the Monte Carlo (MC) method which we are going to consider in this chapter.

description: Porous graphene (PG) forms a class of graphene-related materials with nanoporous architectures. Their unique atomic arrangements present interconnected networks with high surface area and high pore volume. Some remarkable properties of PG, such as high mechanical strength and good thermal stability, have been widely studied. However, their electrical conductivity, and most importantly, their charge transport mechanism are still not fully understood. Herein, we employed a numerical approach based on a 2D tight-binding model Hamiltonian to first reveal the nature of the charge transport mechanism in PG nanoribbons. Results showed that the charge transport in these materials is mediated by charge density waves. These carrier species are dynamically stable and present very shallow lattice distortions. The porosity allows for an alternative to the usual arising of polaron-like charge carriers and it can preserve the PG semiconducting character even in broader nanoribbons. The charge density waves move in PG within the optical regime with terminal velocities varying from 0.50 up to 1.15 A/fs. These velocities are lower than the ones for polarons in conventional graphene nanoribbons (2.2-5.1 A/fs).

description: We present time series analyses of three-decade long radio observations of the BL Lacertae object AO 0235+164 made at the University of Michigan Radio Astronomical Observatory operating at three central frequencies of 4.8 GHz, 8.0 GHz and 14.5 GHz. We detected a quasi-periodic oscillation of $\sim$965 days in all three frequency bands in the light curve of the effectively simultaneous observations, along with strong signals at $\sim$1950 d, $\sim$1350 d, and $\sim$660 d. The periodicity is analyzed with three methods: Data Compensated Discrete Fourier Transform, Generalized Lomb-Scargle Periodogram and Weighted Wavelet Z-transform. These methods are chosen as they have different analysis approaches toward robust measurement of claimed periodicities. The QPO at $965\pm 50$ days is found to be significant (at least $3.5σ$) and is persistent throughout the observation for all three radio frequencies, and the others, which may be harmonics, are comparably significant in at least the 8.0 GHz and 14.5 GHz bands. We briefly discuss plausible explanations for the origin of such long and persistent periodicity.

description: Recently, significant interest has emerged in fabricated systems that mimic the behavior of geometrically-frustrated materials. We present the full realization of such an artificial spin ice system on a two-dimensional kagome lattice and demonstrate rigid adherence to the local ice rule by directly counting individual pseudo-spins. The resulting spin configurations show not only local ice rules and long-range disorder, but also correlations consistent with spin ice Monte Carlo calculations. Our results suggest that dipolar corrections are significant in this system, as in pyrochlore spin ice, and they open a door to further studies of frustration in general.

description: Intermolecular bonds are weak compared to covalent bonds, but they are strong enough to influence the properties of large molecular systems. In this work, we investigate how strong light-matter coupling inside an optical cavity can modify these intermolecular forces. We perform a detailed comparison between currently available ab initio electron-photon methodologies. The electromagnetic field inside the cavity can modulate the ground state properties of weakly bound complexes. Controlling the field polarization, the interactions can be stabilized or destabilized, and electron densities, dipole moments, and polarizabilities can be altered. We demonstrate that electron-photon correlation is fundamental to describe intermolecular interactions in strong light-matter coupling. This work proposes optical cavities as a novel tool to manipulate and control ground state properties, solvent effects, and intermolecular interactions for molecules and materials.

description: We continue the analysis of NuSTAR data from the recent discovery outburst of MAXI J1820+070 (optical counterpart ASASSN-18ey), focussing on an observation including unusual flaring behaviour during the hard to soft state transition, which is a short phase of outbursts and so comparatively rarely observed. Two plateaus in flux are separated by a variable interval lasting ~10 ks, which shows dipping then flaring stages. The variability is strongest (with fractional variability up to $F_{\rm Var}\sim10\%$) at high energies and reduces as the contribution from disc emission becomes stronger. Flux-resolved spectra show that the variability is primarily due to the power law flux changing. We also find a long soft lag of the thermal behind the power law emission, which is $20_{-1.2}^{+1.6}$ s during the flaring phase. The lag during the dipping stage has a different lag-energy spectrum, which may be due to a wave passing outwards through the disc. Time resolved spectral fitting suggests that the lag during the flaring stage may be due to the disc re-filling after being disrupted to produce the power law flare, perhaps related to the system settling after the jet ejection which occurred around 1 day before. The timescales of these phenomena imply a low viscosity parameter, $α\sim10^{-3}$, for the inner region of the disc.

Intertidal community structure, dynamics and models : mechanisms and the role of biotic and abiotic interaction
Creators: name: Kim, Jeong Ha
Publisher: name: University of British Columbia
Year: 2009

description: This study is a comprehensive and experimental approach to understand the dynamics producing structure in an intertidal algal community. Both biological factors (competition and herbivory) and physical factors (disturbance and physical stress) were investigated through field manipulative experiments, non-manipulative monitoring and laboratory experiments for the last 3 years in Barkley Sound, Vancouver Island. The community studied contains three dominant perennial macroalgae, Mazzaella cornucopiae (Rhodophyta), Fucus distichus and Pelvetiopsis limitata (Phaeophyta), and some ephemeral algae as well as coexisting invertebrates such as barnacles, limpets and snails. Biological interactions and their mechanisms for all these organisms turned out to be complicated and non-hierarchical interaction networks which include reversal of dominance and indirect interaction. There was evidence for both negative and positive interactions existing between the same pair of species. Competitive dominance was changed depending on the developmental stages of the competitors and due to differences in morphology, and also the outcomes of interactions were modified by physical stresses (i.e., desiccation and wave action). Snails preferentially grazed the red alga, and limpets reduced the abundance of the ephemeral algae (the early colonizers) which otherwise inhibited the settlement of the later successional species such as the fucoids. Barnacles facilitated the colonization of Fucus and ephemeral algae after disturbance. Responses of the three dominant algae and ephemerals to the different sizes and time of disturbance were species-specific and depended on the alga’s life history and reproductive characteristics. The study shows that both the biological and physical factors influenced the structure of this community, and that the non-hierarchical interactions among the major species and their well-balanced responses to disturbance support a high likelihood of maintaining the current diversity in this algal community.

description: The new lightest gauge boson $B_H$ with mass of a few hundred GeV is predicted in the littlest Higgs model. $B_H$ should be accessible in the planed ILC and the observation of such particle can strongly support the littlest Higgs model. The realization of $γγ$ and $eγ$ collision will open a wider window to probe $B_H$. In this paper, we study the new gauge boson $B_{H}$ production processes $e^{-}γ\to e^{-}γB_{H}$ and $e^{-}γ\to e^{-}Z B_{H}$ at the ILC. Our results show that the production cross section of the process $e^{-}γ\to e^{-}Z B_{H}$ is less than one fb in the most parameter spaces while the production cross section of the process $e^{-}γ\to e^{-}γB_{H}$ can reach the level of tens fb and even hundreds of fb in the sizable parameter spaces allowed by the electroweak precision data. With the high luminosity, the sufficient typical signals could be produced, specially via $e^{-}γ\to e^{-}γB_{H}$. Because the final electron and photon beams can be easily identified and the signal can be easily distinguished from the background produced by $Z$ and $H$ decaying, $B_H$ should be detectable via $eγ$ collision at the ILC. Therefore, the processes $e^{-}γ\to e^{-}γB_{H}$ and $e^{-}γ\to e^{-}Z B_{H}$ provide a useful way to detect $B_{H}$ and test the littlest Higgs model.

description: Context: There is a growing demand for information on how IT companies look for candidates to their open positions. Objective: This paper investigates which hard and soft skills are more required in IT companies by analyzing the description of 20,000 job opportunities. Method: We applied open card sorting to perform a high-level analysis on which types of hard skills are more requested. Further, we manually analyzed the most mentioned soft skills. Results: Programming languages are the most demanded hard skills. Communication, collaboration, and problem-solving are the most demanded soft skills. Conclusion: We recommend developers to organize their resumé according to the positions they are applying. We also highlight the importance of soft skills, as they appear in many job opportunities.

description: We consider the problem of estimating the conditional probability distribution of missing values given the observed ones. We propose an approach, which combines the flexibility of deep neural networks with the simplicity of Gaussian mixture models (GMMs). Given an incomplete data point, our neural network returns the parameters of Gaussian distribution (in the form of Factor Analyzers model) representing the corresponding conditional density. We experimentally verify that our model provides better log-likelihood than conditional GMM trained in a typical way. Moreover, imputation obtained by replacing missing values using the mean vector of our model looks visually plausible.

description: The first evidence of new strong interactions may be a sufficiently massive fourth family observed at the LHC. The fourth family masses, of the leptons in particular, are constrained by the electroweak precision data, and this leads to signatures at the LHC that may imply early discovery. We study the implications of this discovery from a bottom-up perspective, where effective 4-fermion operators model the dominant effects of the new dynamics. We identify simple approximate symmetries of these operators that may be required for realistic masses of the third and fourth families. The large top mass for instance is related to the structure of these operators.

description: An electrostatic time-of-flight detector named E-MCP has been developed for quick diagnostics of circulating beam and timing measurement in mass spectrometry at the Rare-RI Ring in RIKEN. The E-MCP detector consists of a conversion foil, potential grids, and a microchannel plate. Secondary electrons are released from the surface of the foil when a heavy ion hits it. The electrons are accelerated and deflected by 90$^\circ$ toward the microchannel plate by electrostatic potentials. A thin carbon foil and a thin aluminum-coated mylar foil were used as conversion foils. We obtained time resolutions of 69(1) ps and 43(1) ps (standard deviation) for a $^{84}$Kr beam at an energy of 170 MeV/u when using the carbon and the aluminum-coated mylar foils, respectively. A detection efficiency of approximately 90% was obtained for both foils. The E-MCP detector equipped with the carbon foil was installed inside the Rare-RI Ring to confirm particle circulation within a demonstration experiment on mass measurements of nuclei around $^{78}$Ge produced by in-flight fission of uranium beam at the RI Beam Factory in RIKEN. Periodic time signals from circulating ions were clearly observed. Revolution times for $^{78}$Ge, $^{77}$Ga, and $^{76}$Zn were obtained. The results confirmed successful circulation of the short-lived nuclei inside the Rare-RI Ring.

We show that an initially separated Gaussian state can become entangled as a result of a purely noisy mechanism. In certain cases, the dissipative dynamics allows the persistence of these bath induced quantum correlations even in the asymptotic equilibrium state.

description: Density estimation, compression and data generation are crucial tasks in artificial intelligence. Variational Auto-Encoders (VAEs) constitute a single framework to achieve these goals. Here, we present a novel class of generative models, called self-supervised Variational Auto-Encoder (selfVAE), that utilizes deterministic and discrete variational posteriors. This class of models allows to perform both conditional and unconditional sampling, while simplifying the objective function. First, we use a single self-supervised transformation as a latent variable, where a transformation is either downscaling or edge detection. Next, we consider a hierarchical architecture, i.e., multiple transformations, and we show its benefits compared to the VAE. The flexibility of selfVAE in data reconstruction finds a particularly interesting use case in data compression tasks, where we can trade-off memory for better data quality, and vice-versa. We present performance of our approach on three benchmark image data (Cifar10, Imagenette64, and CelebA).

While the short-range exchange functionals are calculated analytically, Coupled-Cluster and Fermi-hypernetted chain calculations are carried out for the correlation energy and the results are fitted to an analytical parametrization. These data enable to construct the local density approximation corresponding to these modified interactions.

Self-employment and the nature of the contemporary Canadian economy
Creators: name: Arai, Alfred Bruce
Publisher: name: University of British Columbia
Year: 2009

description: Recent transformations within modern economies have often been discussed under the concept of “restructuring”. However this term, despite its widespread use in sociology, has little explanatory power. What is needed instead is a consideration of how restructuring has taken place. Three major theoretical positions which attempt to provide this understanding are Marxist monopoly captialism, post-fordism and post-industrialism. Each of these paradigms provides a different understanding of the nature and operation of contemporary capitalist formations. My purpose in this thesis is to determine which of these different viewpoints is most applicable to the Canadian situation. I will do so through an examination of changes in the self-employed sector of the Canadian economy since 1960. The self-employed sector, besides being of intrinsic interest because of its recent attention by politicians and the popular media, is an important testing ground for the relative validity of the above theories in the Canadian context. Each framework is consistent with a set of well-defined and contrasting predictions about what should happen to the overall size of the self-employed sector, as well as expectations about the direction of ascriptive inequality, both within the sector and in the larger society. Using time series regression procedures, declines and increases in the size of the entrepreneurial sector over the last thirty or so years are documented. In addition, the importance of increases in the sector is examined by modelling the effect of unemployment on self-employment. Predictions about ascriptive inequalities are tested through an investigation of earnings functions within the self-employed and employed populations. The results of these analyses suggest that a post-fordist understanding of the contemporary Canadian economy is most appropriate. Self-employment has clearly increased since 1960, and ascriptive inequalities, particularly by gender, have persisted throughout much ofthe latter half of this period. The implication of this is that in order to understand the larger processes shaping our economy, as well as the nature of work beyond self-employment, we are most likely to find answers in discussions about post-fordism.

description: Supermassive stars (SMSs) with $\sim10^{4-5}~\mathrm{M}_{\odot}$ are candidate objects for the origin of supermassive black holes observed at redshift $z$>6. They are supposed to form in primordial-gas clouds that provide the central stars with gas at a high accretion rate, but their growth may be terminated in the middle due to the stellar ionizing radiation if the accretion is intermittent and its quiescent periods are longer than the Kelvin-Helmholtz (KH) timescales at the stellar surfaces. In this paper, we examine the role of the ionizing radiation feedback based on the accretion history in two possible SMS-forming clouds extracted from cosmological simulations, following their evolution with vertically-integrated two-dimensional hydrodynamic simulations with detailed thermal and chemical models. The consistent treatment of the gas thermal evolution is crucial for obtaining the realistic accretion history, as we demonstrate by performing an additional run with a barotropic equation of state, in which the fluctuation of the accretion rate is artificially suppressed. We find that although the accretion becomes intermittent due to the formation of spiral arms and clumps in gravitationally unstable disks, the quiescent periods are always shorter than the KH timescales, implying that SMSs can form without affected by the ionizing radiation.

description: While stroke is becoming increasingly prevalent in young people (<65 years), diagnosis, treatment, rehabilitation, and management continue to reflect the needs of older people. This study aimed to characterise and appreciate the healthcare experiences of young stroke survivors, whose needs and trajectories differ from those of older people. Qualitative in-depth semi-structured interviews were conducted with 11 stroke survivors aged 18–49 using virtual conferencing software. The data were analysed using interpretative phenomenological analysis. Four main themes were identified that reflect the experiences and needs of young stroke survivors and are (1) The health system overlooks the experiences and needs of young stroke survivors; (2) Support is fragmented rather than holistic; (3) Feelings of helplessness at a time agency is required; and (4) Positive attitudes despite challenges. The experiences of young stroke survivors are distinct. Health services that consider the unique trajectories of young stroke survivors will better facilitate rehabilitation and support for this population.

Ο ΚΠ – ο ασθενής που μελετάται εδώ – μετά από εγκεφαλικό επεισόδιο στην ατρακτοειδή έλικα παρουσίασε μεγαλύτερο ορθογραφικό έλλειμμα στην τροπικότητα της γραφής σε σχέση με την ανάγνωση. Η αξιολόγηση του ασθενούς έδειξε προβλήματα σε έργα γραφής σε σχέση με την ανάγνωση και ορισμένες δυσκολίες σε έργο λεξικής απόφασης. Τα αποτελέσματα ερμηνεύονται στα πλαίσια θεωριών για την ύπαρξη ενός ενιαίου ορθογραφικού συστήματος ή δύο ξεχωριστών συστημάτων ορθογραφικής επεξεργασίας (ανάγνωσης και γραφής). Υποστηρίζεται ότι το προφίλ των διαταραχών διαμορφώνεται και αντανακλά το ορθογραφικό βάθος μιας γλώσσας και εν προκειμένω της ελληνικής γλώσσας.
description: This paper investigates the effect of orthographic depth of language in reading and spelling after damage to fusiform gyrus. The Greek language is characterized by a dual character, it has shallow orthography in reading and deep orthography in spelling. KP - the patient studied here – suffered a stroke affecting mainly the right fusiform gyrus and the caudal part of the corpus callosum and presented initially a reading deficits which resolved 2 years later to a pronounced surface dysgraphia. The evaluation of the patient revealed problems in writing as well as reading difficulties in some lexical decision tasks. The results are interpreted within theories of a uniform spelling system or two separate systems processing for spelling. It is argued that reading and spelling may share the same neural structures but these processes can be differentially affected depending on the orthographic depth of each language.

description: Only several compounds bearing Ag(II) cation and other transition metal cation have been known. Herein, we predict stability and crystal structures of hypothetical ternary silver(II) fluorides with copper, nickel and cobalt in 1:1 stoichiometry at pressure range from 0 GPa up to 20 GPa within the frame of Density Functional Theory. Calculations show that AgCoF4 could be synthesized already at ambient conditions but this compound would host diamagnetic Ag(I) and high-spin Co(III). However, at increased pressure ternary fluorides of Ag(II) featuring Cu and Ni could be synthesized, in the pressure windows of 7-14 and 8-15 GPa, respectively. All title compounds would be semiconducting and magnetically ordered.

Τέλος, πραγματοποιήθηκε σύγκριση και αξιολόγηση μεταξύ των νέων υποδομών και των υποδομών πεζοδρόμων του κέντρου της πόλης.
description: The basic aim of the present Master Thesis is to evaluate the level of service as perceived by the pedestrians, cyclists, children, elderly, people with disabilities during their trips in Thessaloniki’s eastern part and especially at the coastal zone at Nea Paralia in Thessaloniki. For this reason, a questionnaire based survey was carried out in order to collect the necessary data. The data collection was carried out in regard to the characteristics of all the coastal zone’s users, the problems that they find during their trips at the inshore zone and the level of their satisfaction. After the questionnaire analysis, proposals were arisen for a friendlier, safer and more comfortable environment for pedestrians, cyclists, children, elderly and people with disabilities. Finally, a comparison between the new infrastructure which Nea Paralia offers and the infrastructures which pedestrian streets offer at the center of the city took place in the present Master Thesis in order to come about useful conclusions.

description: It has been suggested that re-expressing relativity in terms of forces could provide fresh insights. The formalism developed for this purpose only applied to static, or conformally static, space-times. Here we extend it to arbitrary space-times. It is hoped that this formalism may lead to a workable definition of mass and energy in relativity.

KK-Masses in Dipole Deformed Field Theories

Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We reconsider aspects of non-commutative dipole deformations of field theories. Among our findings there are hints to new phases with spontaneous breaking of translation invariance (stripe phases), similar to what happens in Moyal-deformed field theories. Furthermore, using zeta-function regularization, we calculate quantum corrections to KK-state masses. The corrections coming from non-planar diagrams show interesting but non-universal behaviour. Depending on the type of interaction the corrections can make the KK-states very heavy but also very light or even tachyonic. Finally we point out that the dipole deformation of QED is not renormalizable!

Rapid evolution of [WC] stars in the Magellanic Clouds

description: We obtained new spectra of fourteen Magellanic Cloud planetary nebulae with the South African Large Telescope to determine heating rates of their central stars and to verify evolutionary models of post-asymptotic giant branch stars. We compared new spectra with observations made in previous years. Five planetary nebulae showed an increase in excitation over time. Four of their central stars exhibit [WC] features in their spectra, including three new detections. This raises the total number of [WC] central stars of PNe in the Magellanic Clouds to ten. We compared determined heating rates of the four [WC] central stars with the He-burning post-asymptotic giant branch evolutionary tracks and the remaining star with the H-burning tracks. Determined heating rates are consistent with the evolutionary models for both H and He-burning post-asymptotic giant branch stars. The central stars of the PNe that show the fastest increase of excitation are also the most luminous in the sample. This indicates that [WC] central stars in the Magellanic Clouds evolve faster than H-burning central stars, and they originate from more massive progenitors.

Universality in asymptotic bounds and its saturation in $2$D CFT

description: We study asymptotics of three point coefficients (light-light-heavy) and two point correlators in heavy states in unitary, compact $2$D CFTs. We prove an upper and lower bound on such quantities using numerically assisted Tauberian techniques. We obtain an optimal upper bound on the spectrum of operators appearing with fixed spin from the OPE of two identical scalars. While all the CFTs obey this bound, rational CFTs come close to saturating it. This mimics the scenario of bounds on asymptotic density of states and thereby pronounces an universal feature in asymptotics of 2D CFTs. Next, we clarify the role of smearing in interpreting the asymptotic results pertaining to considerations of eigenstate thermalization in 2D CFTs. In the context of light-light-heavy three point coefficients, we find that the order one number in the bound is sensitive to how close the light operators are from the $\frac{c}{32}$ threshold. In context of two point correlator in heavy state, we find the presence of an enigmatic regime which separates the $AdS_3$ thermal physics and the BTZ black hole physics. Furthermore, we present some new numerical results on the behavior of spherical conformal block.
