title: Real time public transport priority

description: Improving the effectiveness of transit signal priority operations has been the subject of considerable research and the results show that the unintended bus delay can be significantly reduced. A major controversy, though, is that these methodologies may bring excessive delays on non-prioritized junctions, as their assigned greens are shortened. Also, a very common dilemma appears is cases where two buses request priority from conflicting directions. In this thesis a real time public transport priority methodology is presented and evaluated. This methodology aims to change the signal plan locally in favor of a bus when this bus is detected and priority is requested. The strategy is based on rules while two different priority levels exist. Depending on the position of the bus and the current signal phase, the strategy chooses either to extend the green time or to reduce the red time of the bus. For conflicting priority requests a number of criteria must be taken into account in order to serve both requests, if feasible, otherwise in order to decide which bus should be served first. This strategy can be easily implemented at different road networks. Additionally, when a signal phase is modified for the implementation of a bus priority traffic plan, then it can be easily adjusted to the initial signal plan without affecting the rest of the network.  The methodology is implemented in a microscopic simulation environment emulating a part of the urban network of Chania with realistic traffic conditions. The criteria used for the assessment of the methodology are the average delay time, the average harmonic speed and the CO emissions. It is shown that all the criteria for the buses are significantly improved without really affecting the rest of the vehicles in the network.

description: We present a new direct spectroscopic calibration for a fast estimation of the stellar metallicity [Fe/H]. These calibrations were computed using a large sample of 451 solar-type stars for which we have precise spectroscopic parameters derived from high quality spectra. The new [Fe/H] calibration is based on weak Fe I lines, which are expected to be less dependent on surface gravity and microturbulence, and require only a pre-determination of the effective temperature. This temperature can be obtained using a previously presented line-ratio calibration. We also present a simple code that uses the calibrations and procedures presented in these works to obtain both the effective temperature and the [Fe/H] estimate. The code, written in C, is freely available for the community and may be used as an extension of the ARES code. We test these calibrations for 582 independent FGK stars. We show that the code can be used as a precise and fast indicator of the spectroscopic temperature and metallicity for dwarf FKG stars with effective temperatures ranging from 4500 K to 6500 K and with [Fe/H] ranging from -0.8 dex to 0.4 dex.

description: We discuss a scenario for the very faint X-ray transients as X-ray binaries fed by winds from detached M-dwarf donors in binary stars within the "period gap" -- the range of periods where donor stars have become fully convective, and shrunken so that they no longer fill their Roche lobes, but have not yet re-attached due to the systems shrinking through gravitational radiation. This wind-fed detached binary scenario can reproduce the two key properties of the very faint X-ray transients -- their faintness, which defines them, and their relatively low duty cycle outbursts which require that they have low mean mass transfer rates. We discuss feasible observational tests of the scenario.

description: The internal state of a cell in a coupled cell network is often described by an element of a vector space. Synchrony or anti-synchrony occurs when some of the cells are in the same or the opposite state. Subspaces of the state space containing cells in synchrony or anti-synchrony are called polydiagonal subspaces. We study the properties of several types of polydiagonal subspaces of weighted coupled cell networks. In particular, we count the number of such subspaces and study when they are dynamically invariant. Of special interest are the evenly tagged anti-synchrony subspaces in which the number of cells in a certain state is equal to the number of cells in the opposite state. Our main theorem shows that the dynamically invariant polydiagonal subspaces determined by certain types of couplings are either synchrony subspaces or evenly tagged anti-synchrony subspaces. A special case of this result confirms a conjecture about difference-coupled graph network systems.

description: The notion of a toric origami manifold, which weakens the notion of a symplectic toric manifold, was introduced by Cannas da Silva-Guillemin-Pires \cite{ca-gu-pi11} and they show that toric origami manifolds bijectively correspond to origami templates via moment maps, where an origami template is a collection of Delzant polytopes with some folding data. Like a fan is associated to a Delzant polytope, a multi-fan introduced in \cite{ha-ma03} and \cite{masu99} can be associated to an oriented origami template. In this paper, we discuss their relationship and show that any simply connected compact smooth 4-manifold with a smooth action of $T^2$ can be a toric origami manifold. We also characterize products of even dimensional spheres which can be toric origami manifolds.

description: Lattice four-fermion models containing $N$ flavors of staggered fermions, that are invariant under $Z_2$ and U(1) chiral symmetries, are known to suffer from sign problems when formulated using the auxiliary field approach. Although these problems have been ignored in previous studies, they can be severe. In this talk, we show that the sign problems disappear when the models are formulated in the fermion bag approach, allowing us to solve them rigorously for the first time.

Copromycodiversity - taxonomy and ecology of dung-inhabiting fungi.pdf
Creators: name: Calaça, Francisco
Publisher: name: figshare
Year: 2022
Subjects: Mycology

description: We define copromycodiversity as all the morphological, physiological, functional, and ecological diversity of an assemblage of dung-inhabiting fungi, also known as coprophilous fungi. These fungi are represented by species of the phyla Ascomycota, Basidiomycota, and Mucoromycota in the sensu stricto of the Kingdom. Traditionally, other groups of organisms, such as some species of protists from the phylum Amoebozoa (Myxomycetes) can also be found associated with these substrates, being studied together with fungi, here in sensu lato. This fungal group is responsible for the maintenance of supporting ecosystem services, essential for life as we know it, acting in the cycling of matter and energy via dung decomposition. Despite this, there are still few studies involving these organisms. In this thesis, we seek to contribute to expanding scientific knowledge about dung-inhabiting fungi (sensu lato), whether in terms of their biology, ecology, or taxonomy. We begin by promoting a synthesis of knowledge as well as a scientometric analysis of the first studies in Brazil and in the world, in addition to an updated list of species and their geographic distribution, adding new occurrences. We compile data on the occurrence and applications of the genus Chaetomium, a fimicolous fungal genus, which means that its species are found associated with both dung and decaying plant debris, as well as developed a proposal for a life cycle for dung-inhabiting fungi, contemplating both the coprophilous and fimicolous cycles. We show how differences in the type of digestive tract of the animal that originated the dung can influence the taxonomic diversity and ecological profiles of species of fungi that inhabit this substrate. Furthermore, we evaluated, in a microcosm experiment, the durability, decomposition rate, and nutritional composition of cattle and equine dung as suitable substrates for the development of coprophilous organisms. Finally, we present the experience report on how we are using social media to communicate fungal biology to the public, developing media strategies to publicize different aspects of our research with dung-inhabiting fungi as well as other fungal groups to the general community. It is expected that the data presented here can contribute to the expansion of knowledge about these fungi, reducing the gap in knowledge about biology, ecology, distribution, and productivity, especially in Brazil. In addition, we hope to encourage the training of human resources as well as the development of additional studies that will contribute to an increasingly better understanding of copromycodiversity.

description: The Majorana stellar representation is used to characterize spin states that have a maximally negative Wigner quasiprobability distribution on a spherical phase space. These maximally Wigner-negative spin states generally exhibit a partial but not high degree of symmetry within their star configurations. In particular, for spin $j > 2$, maximal constellations do not correspond to a Platonic solid when available and do not follow an obvious geometric pattern as dimension increases. In addition, they are generally different from spin states that maximize other measures of nonclassicality such as anticoherence or geometric entanglement. Random states ($j \leq 6$) display on average a relatively high amount of negativity, but the extremal states and those with similar negativity are statistically rare in Hilbert space. We also prove that all spin coherent states of arbitrary dimension have non-zero Wigner negativity. This offers evidence that all pure spin states also have non-zero Wigner negativity. The results can be applied to qubit ensembles exhibiting permutation invariance.

description: High energy cosmic rays "illuminate" the Sun and produce an image that could be observed in up to five different channels: a cosmic ray shadow (whose energy dependence has been studied by HAWC); a gamma ray flux (observed at $E\le 200$ GeV by Fermi-LAT); a muon shadow (detected by ANTARES and IceCube); a neutron flux (undetected, as there are no hadronic calorimeters in space); and a flux of high energy neutrinos. Since these signals are correlated, the ones already observed can be used to reduce the uncertainty in the still undetected ones. Here we define a simple set up that uses the Fermi-LAT and HAWC observations to imply very definite fluxes of neutrons and neutrinos from the solar disk. In particular, we provide a fit of the neutrino flux at 10 GeV-10 TeV that includes its dependence on the zenith angle and on the period of the solar cycle. This flux represents a neutrino floor in indirect dark matter searches. We show that in some benchmark models the current bounds on the dark matter-nucleon cross section push the solar signal below this neutrino floor.

description: In this work we investigate the impact of conformal symmetry breaking on hydrodynamization of a far-from-equilibrium fluid. We find a new kind of transseries solutions for the non-conformal hydrodynamic equations of a longitudinal boost invariant expanding plasma. The new transseries solutions unveil a rich physical structure which arises due to the interplay of different physical scales. In the perfect fluid case the non-conformal speed of sound slows down the cooling of the temperature due to the emergence of logarithmic corrections that depends on the mass of the particle. These terms propagate into the perturbative and non-perturbative sectors of the transseries once viscous corrections are included. The logarithmic mass contributions increase the asymptotic value of the Knudsen number while decreasing the damping rate of the transient non-hydrodynamic modes and thus, yielding to an extremely slow hydrodynamization process where flow lines merge to their forward attractor at extremely late times. The early time free streaming expansion is modified and receives logarithmic mass corrections induced by the shear-bulk couplings. The global flow structure and numerical analyses carried out in our work demonstrate the existence of the early and late-time attractors for the shear viscous tensor and bulk viscous pressure.

description: Generalization is one of the most important problems in deep learning (DL). In the overparameterized regime in neural networks, there exist many low-loss solutions that fit the training data equally well. The key question is which solution is more generalizable. Empirical studies showed a strong correlation between flatness of the loss landscape at a solution and its generalizability, and stochastic gradient descent (SGD) is crucial in finding the flat solutions. To understand how SGD drives the learning system to flat solutions, we construct a simple model whose loss landscape has a continuous set of degenerate (or near degenerate) minima. By solving the Fokker-Planck equation of the underlying stochastic learning dynamics, we show that due to its strong anisotropy the SGD noise introduces an additional effective loss term that decreases with flatness and has an overall strength that increases with the learning rate and batch-to-batch variation. We find that the additional landscape-dependent SGD-loss breaks the degeneracy and serves as an effective regularization for finding flat solutions. Furthermore, a stronger SGD noise shortens the convergence time to the flat solutions. However, we identify an upper bound for the SGD noise beyond which the system fails to converge. Our results not only elucidate the role of SGD for generalization they may also have important implications for hyperparameter selection for learning efficiently without divergence.

description: In order to test a recent hypothesis that the dispersion in the Schmidt-Kennicutt law arises from variations in the evolutionary stage of star forming molecular clouds, we compared molecular gas and recent star formation in an early-phase merger galaxy pair, Taffy I (UGC\ 12915/UGC\ 12914, VV\ 254) which went through a direct collision 20 Myr ago and whose star forming regions are expected to have similar ages. Narrow-band Pa-alpha image is obtained using the ANIR near-infrared camera on the mini-TAO 1m telescope. The image enables us to derive accurate star formation rates within the galaxy directly. The total star formation rate, 22.2 M_sun/yr, was found to be much higher than previous estimates. Ages of individual star forming blobs estimated from equivalent widths indicate that most star forming regions are ~7 Myr old, except for a giant HII region at the bridge which is much younger. Comparison between star formation rates and molecular gas masses for the regions with the same age exhibits a surprisingly tight correlation, a slope of unity, and star formation efficiencies comparable to those of starburst galaxies. These results suggest that Taffy I has just evolved into a starburst system after the collision, and the star forming sites are at a similar stage in their evolution from natal molecular clouds except for the bridge region. The tight Schmidt-Kennicutt law supports the scenario that dispersion in the star formation law is in large part due to differences in evolutionary stage of star forming regions.

description: Cluster abundances are oddly insensitive to canonical early dark energy. Early dark energy with sound speed equal to the speed of light cannot be distinguished from a quintessence model with the equivalent expansion history for $z<2$ but negligible early dark energy density, despite the different early growth rate. However, cold early dark energy, with a sound speed much smaller than the speed of light, can give a detectable signature. Combining cluster abundances with cosmic microwave background power spectra can determine the early dark energy fraction to 0.3 % and distinguish a true sound speed of 0.1 from 1 at 99 % confidence. We project constraints on early dark energy from the Euclid cluster survey, as well as the Dark Energy Survey, using both current and projected Planck CMB data, and assess the impact of cluster mass systematics. We also quantify the importance of dark energy perturbations, and the role of sound speed during a crossing of $w=-1$.

This result is based on an explicit expression for the generating function of Poincare polynomials of these spaces. There is a variant of quantum Hamiltonian reduction that realizes vertex algebras which we call iterated W-algebras and our main conjecture is that the vertex algebras associated to the affine Laumon spaces are subalgebras of iterated W-algebras.

description: Interplay between the topological surface states and bulk states gives rise to diverse exotic transport phenomena in topological materials. The recently proposed Weyl orbit in topological semimetals in the presence of magnetic field is a remarkable example. This novel closed magnetic orbit consists of Fermi arcs on two spatially separated sample surfaces which are connected by the bulk chiral zero mode, which can contribute to transport. Here we report Shubnikov-de Haas (SdH) oscillation and its evolution into quantum Hall effect (QHE) in multilayered type-II Weyl semimetal WTe2. We observe both the three-dimensional (3D) QHE from bulk states by parallelly stacking of confined two-dimensional layers in the low magnetic field region and the 3D QHE in the quantized surface transport due to Weyl orbits in the high magnetic field region. Our study of the two types of novel QHEs controlled by magnetic field and our demonstration of the crossover between quantized bulk and surface transport provide an essential platform for the future quantized transport studies in topological semimetals.

description: Equilibrium mechanical unfolding of a globule formed by long flexible homopolymer chain collapsed in a poor solvent and subjected to an extensional force f (force-clamp mode) or extensional deformation D (position-clamp mode) is studied theoretically. Our analysis, like all previous analysis of this problem, shows that the globule behaves essentially differently in two modes of extension. In the force-clamp mode, mechanical unfolding of the globule with increasing applied force occurs without intramolecular microphase segregation, and at certain threshold value of the pulling force the globule unfolds as a whole ("all-or-none" transition). The value of the threshold force and the corresponding jump in the distance between the chain ends increase with a deterioration of the solvent quality and/or with an increase in the degree of polymerization. In the position-clamp mode, the globule unfolding occurs via intramolecular microphase coexistence of globular and extended microphases followed by an abrupt unraveling transition. Reaction force in the microphase segregation regime demonstrates an "anomalous" decrease with increasing extension. Comparison of deformation curves in force and position-clamp modes demonstrates that at weak and strong extensions the curves for two modes coincide, differences are observed in the intermediate extension range. Another unfolding scenario is typical for short globules: in both modes of extension they unfold continuously, without jumps or intramolecular microphase coexistence, by passing a sequence of uniformly elongated configurations.

description: A search is performed for collimated muon pairs displaced from the primary vertex produced in the decay of long-lived neutral particles in proton-proton collisions at sqrt(s) = 7 TeV centre-of-mass energy, with the ATLAS detector at the LHC. In a 1.9 fb-1 event sample collected during 2011, the observed data are consistent with the Standard Model background expectations. Limits on the product of the production cross section and the branching ratio of a Higgs boson decaying to hidden-sector neutral long-lived particles are derived as a function of the particles' mean lifetime.

description: Averaging certain class of quasiperiodic monotone operators can be simplified to the periodic homogenization setting by mapping the original quasiperiodic structure onto a periodic structure in a higher dimensional space using cut-and projection method. We characterize cut-and-projection convergence limit of the nonlinear monotone partial differential operator $-\mathrm{div} \; σ\left({\bf x},\frac{{\bf R}{\bf x}}η, \nabla u_η\right)$ for a bounded sequence $u_η$ in $W^{1,p}_0(Ω)$, where $1

description: Nowadays efficient usage of high-tech security tools and appliances is considered as an important criterion for security improvement of computer networks. Based on this assumption, Intrusion Detection and Prevention Systems (IDPS) have key role for applying the defense in depth strategy. In this situation, by increasing network bandwidth in addition to increasing number of threats, Network-based IDPSes have been faced with performance challenge for processing of huge traffic in the networks. A general solution for this bottleneck is exploitation of efficient hardware architectures for performance improvement of IDPS. In this paper a framework for analysis and performance evaluation of application specific instruction set processors is presented for usage in application of attack detection in Networkbased Intrusion Detection Systems(NIDS). By running this framework as a security application on V850, OR1K, MIPS32, ARM7TDMI and PowerPC32 microprocessors, their performance has been evaluated and analyzed. For performance improvement, the compiler optimization levels are employed and at the end; base on O2 optimization level a new combination of optimization flags is presented. The experiments show that the framework results 18.10% performance improvements for pattern matching on ARM7TDMI microprocessors.

description: Flexible solar cells emerge as the need for clean energy resources arises in many complex scenarios, demanding device tolerance with irregular geometries. Bendable or even foldable devices with atypical form factors fit for a wide range of applications, such as integration with building designs, smart home “Internet-of-Things” systems, wearable electronics. Implementation of nanomaterials into flexible devices, owing to their solution processible and flexible nature, can further lower production costs while improving device flexibility; tunable properties of nanomaterials can also add in versatility of device functions. Ultrathin CuInSe₂ nanocrystal solar cells with a total thickness less than 20 μm, are enabled by both nanomaterial incorporation and photonic lift-off technique. Photonic lift-off provides ultrafast, clean, and high-throughput processing, to separate flexible devices from the underlying rigid support. CuInSe₂ nanocrystal solar cells can be produced in flexible format through the photonic lift-off process, after the device flexibility was greatly improved by the replacement of indium tin oxide in the top contact with spray-coated silver nanowires. In contrast to nanowire assembly produced from spray coating with a disordered morphology, regular assembly of nanowires which exhibits a higher level of uniformity, could lead to enhancement of the intrinsic nanowire properties. A simple toluene-water system, utilizing the interface formed between the two immiscible liquids, is able to drive nanowires to align side by side into monolayers, creating centimeter-wide coverage. Uniformity in nanowire alignment across hundreds of microns gives rise to anisotropic properties such as birefringence, revealing their potential to be used as building blocks of optoelectronics. Last but not the least, near-infrared active plasmonic CuInSe₂ nanocrystals were achieved through cation exchange. A post-synthetic heat treatment of CuInSe₂ nanocrystals with Cd²⁺ sources induced plasmon-enhanced absorption around 0.85 eV. Cd incorporation generates free carriers and expands the pristine chalcopyrite crystal lattice, as a result of the introduced substitutional and interstitial defects. These studies provided deep insights into the structure and properties of solution-processible nanomaterials, to advance their applications for flexible electronic production.

description: Studies of Hamiltonians modeling the coupling between electrons as well as to local phonon excitations have been fundamental in capturing the novel ordering seen in many quasi-one dimensional condensed matter systems. Extending studies of such Hamiltonians to quasi-two dimensional systems is of great current interest, as electron-phonon couplings are predicted to play a major role in the stabilization or enhancement of novel phases in 2D material systems. In this work, we study model systems that describe the interplay between the Hubbard coupling and the phonon modes in the Holstein (H) and Su-Schrieffer-Heeger (SSH) Hamiltonians using the functional renormalization group (fRG). For both types of electron phonon couplings, we find the predicted charge density wave phases in competition with anti-ferromagnetic ($AF$) ordering. As the system is doped, the transition shifts, with both orders showing incommensurate peaks. We compare the evolution of the quasiparticle weight for the Holstein model with that of the SSH model as the systems transition from antiferromagnetic to charge-ordered ground states. Finally, we calculate the self-energy of the phonon and capture the impact of charge ordering on the phonon modes.

title: Jazz education in mainland China: historical and contemporary perspectives
Creators: name: Wang, Linfeng
Publisher: name: University of Glasgow

description: As a popular music genre and significant Western cultural export, jazz music arrived in China during the 1920s. However, previous research has not paid sufficient critical attention to China’s experience of jazz music prior to the 1980s, and there is still a paucity of research into jazz education in China. I will analyse the current state of jazz education in mainland China and the underlying processes and history of its development. The work is significant both in terms of providing new insights into musical and cultural life in mainland China, but also more widely in considering the international transmission of music and music education into different cultures. This research aims to adopt a two-stage approach, rereading the origins and development of jazz and jazz education in China since the 1920s through the optic of history, geography and cultural policy, before using this foundation to reread modern Chinese jazz education. My investigation will employ a combination of fieldwork, involving data collection and analysis of interviews I have conducted, observations, and questionnaires, as well as an examination of Chinese and foreign literature since the 1980s. The research will also be the first to periodise contemporary jazz education in China, building an empirical and methodological framework which may be of benefit to future scholars investigating this area. The three stages include the starting point of contemporary jazz education in China (1978-1993); the period of rapid development of contemporary jazz education (1993-2005); and the mature period of jazz education (2005-2020).

description: A new experimental evaluation of the quenching factor for nuclear recoils in NaI[Tl] is described. Systematics affecting previous measurements are addressed by careful characterization of the emission spectrum of the neutron source, use of a small scintillator coupled to an ultra-bialkali high quantum efficiency photomultiplier, and evaluation of non-linearities in the electron recoil response via Compton scattering. A trend towards a rapidly diminishing quenching factor with decreasing sodium recoil energy is revealed. Additionally, no evidence for crystal lattice channeling of low-energy recoiling ions is found in a scintillator of known crystallographic orientation. A discussion on how these findings affect dark matter searches employing NaI[Tl] (e.g., DAMA/LIBRA) is offered.
