description: We present further results from our ongoing optical spectrophotometric campaign at the Astronomical Observatory of Bologna in Loiano (Italy) on unidentified hard X-ray sources detected by INTEGRAL. We observed spectroscopically the putative optical counterparts of the INTEGRAL sources IGR J00234+6141, IGR J01583+6713, IGR J06074+2205, IGR J13091+1137 and IGR J20286+2544. We find that the first two are Galactic objects, namely a Cataclysmic Variable at a distance of about 300 pc and a Be/X transient High-Mass X-ray Binary (HMXB) located at about 6.4 kpc, respectively, whereas the last one is identified with MCG +04-48-002, a Starburst/HII galaxy at redshift z = 0.013 hiding a Seyfert 2 nucleus. We identify IGR J13091+1137 as the (likely Seyfert 2 type) active nucleus of galaxy NGC 4992, which we classify as an X-ray Bright, Optically Normal Galaxy; this is the first example of this type of object to be detected by INTEGRAL, and one of the closest of this class. We moreover confirm the possible Be/X nature of IGR J06074+2205, and we estimate it to be at a distance of about 1 kpc. We also reexamine the spectrum of the z = 0.087 elliptical radio galaxy PKS 0352-686, the possible counterpart of the INTEGRAL source IGR J03532-6829, and we find that it is a BL Lac. Physical parameters for these sources are also evaluated by discussing our findings in the context of the available multiwavelength information. These identifications further stress the importance of INTEGRAL in the study of the hard X-ray spectrum of Active Galactic Nuclei, HMXBs and Cataclysmic Variables.

description: Recent observations of the Galactic center in high-energy gamma-rays (above 0.1TeV) have opened up new ways to study this region, from understanding the emission source of these high-energy photons to constraining the environment in which they are formed. We present a revised theoretical density model of the inner 5pc surrounding Sgr A* based on the fact that the underlying structure of this region is dominated by the winds from the Wolf-Rayet stars orbiting Sgr A*. An ideal probe and application of this density structure is this high energy gamma-ray emission. We assume a proton-scattering model for the production of these gamma-rays and then determine first whether such a model is consistent with the observations and second whether we can use these observations to further constrain the density distribution in the Galactic center.

description: The purpose of this dissertation was the 3D survey of Pasha Hamam in Thessaloniki. In the first section, some general information are adduced, concerning the way historic buildings, especially the ones dated from the ottoman period, are treated by the political establishment and ordinary citizens, as well as the implementation of any program regarding conservation and restoration interventions. Also, the way in which these historic buildings are treated in the early town planning of Thessaloniki and the architecture of the ottoman hamam are presented. Additional information are staged with respect to public baths and washhouses as part of the religious and social life in the ottoman period, erection and facility limitations imposed by the ottoman jurisprudence and the categorization of Turkish baths, suggested by different researchers. In the next section, the methods of monuments’ surveying are illustrated, emphasizing the measurement of dimensional relationships of an object using laser scanners, along with the operating principles and the types of scanners, the methodology and measurement processing. Through the measurements’ assessment and laser scanning technique’s description, numerous assumptions are made as to the benefits of laser scanning methods, when detailed investigation and mapping of cultural heritage is concerned. The final products of this dissertation are floor plans, sides and sections of the monument

description: This paper uses Fratini’s (2017) actuarial approach and the traditional risk neutral approach to price the revenue insurance under the framework of Black Scholes put option pricing. Then, we extend the pricing to include a coverage limit. Further, we also decompose the revenue into price and yield and develop another pricing formula using the price and yield information. The risk neutral approach assumes that the underlying revenue is tradable while the actuarial approach assumes the revenue risk is diversifiable. We compute the premiums of the revenue insurance of sugar apple and banana in Taiwan. The results show that the premiums of the actuarial approach are generally lower than the risk neutral approach. Because revenue is often non-tradable, thus, if the individual revenue risk can be fully diversified, then the actuarial approach should be suggested for premiums calculation.
The long-term survival chances of young massive star clusters

description: We review the long-term survival chances of young massive star clusters (YMCs), hallmarks of intense starburst episodes often associated with violent galaxy interactions. We address the key question as to whether at least some of these YMCs can be considered proto-globular clusters (GCs), in which case these would be expected to evolve into counterparts of the ubiquitous old GCs believed to be among the oldest galactic building blocks. In the absence of significant external perturbations, the key factor determining a cluster's long-term survival chances is the shape of its stellar initial mass function (IMF). It is, however, not straightforward to assess the IMF shape in unresolved extragalactic YMCs. We discuss in detail the promise of using high-resolution spectroscopy to make progress towards this goal, as well as the numerous pitfalls associated with this approach. We also discuss the latest progress in worldwide efforts to better understand the evolution of entire cluster systems, the disruption processes they are affected by, and whether we can use recently gained insights to determine the nature of at least some of the YMCs observed in extragalactic starbursts as proto-GCs. We conclude that there is an increasing body of evidence that GC formation appears to be continuing until today; their long-term evolution crucially depends on their environmental conditions, however.

description: We present the structural and initial magnetic characterization of the previously unreported materials NdPd5Ge3 and NdPd5Ge3. These materials, with 1-dimensional Nd chains, crystallize in the orthorhombic YNi5Si3-type structure in space group Pnma. Magnetic ordering is observed for both compounds at ~ 2.2 K for NdPd5Ge3 and ~ 3.0 K for NdPt5Ge3. A magnetic-field-induced transition is clearly observed for NdPd5Ge3 below 2K, at an applied magnetic field of around 1.6 Tesla. The heat capacity data reveals that essentially all the available magnetic entropy is released at the magnetic ordering transition for NdPd5Ge3 but that only 29% is seen for NdPt5Ge3 at temperatures down to 1.5 K, the data implying that a second magnetic transition can be expected at lower temperatures.

description: We present a model for generating postage stamp images of synthetic Fanaroff-Riley Class I and Class II radio galaxies suitable for use in simulations of future radio surveys such as those being developed for the Square Kilometre Array. This model uses a fully-connected neural network to implement structured variational inference through a variational auto-encoder and decoder architecture. In order to optimise the dimensionality of the latent space for the auto-encoder we introduce the radio morphology inception score (RAMIS), a quantitative method for assessing the quality of generated images, and discuss in detail how data pre-processing choices can affect the value of this measure. We examine the 2-dimensional latent space of the VAEs and discuss how this can be used to control the generation of synthetic populations, whilst also cautioning how it may lead to biases when used for data augmentation.

description: We present in analytic form the O(alpha_s^5) correction to the H->gg partial width of the standard-model Higgs boson with intermediate mass M_H<2M_t. Its knowledge is useful because the O(alpha_s^4) correction is sizeable (around 20%). For M_H=120 GeV, the resulting QCD correction factor reads 1 + (215/12) alpha_s^(5)(M_H)/pi + 152.5 (alpha_s^(5)(M_H)/pi)^2 + 381.5 (alpha_s^(5)(M_H)/pi)^3 \approx 1+0.65+0.20+0.02. The new four-loop correction increases the total Higgs-boson hadronic width by a small amount of order 1 promille and stabilizes significantly the residual scale dependence.

description: Some indirect observations, as the high fraction of Be stars at low metallicity, or the necessity for massive stars to be important sources of primary nitrogen, seem to indicate that very metal poor stars were fast rotators. As a consequence of this fast rotation, these stars, contrarily to current wisdom, might lose large amounts of mass during their lifetime. In this paper, we review various mechanisms triggered by rotation which may induce strong mass loss at very low metallicity. The most efficient process comes from surface enrichments in CNO elements which then drive mass loss by stellar winds. Due to this process, a fast rotating 60 M$_\odot$ with metallicities in the range of $Z=10^{-8}$ and $10^{-5}$, can lose between 30 and 55% of its initial mass. This rotationally wind ejected material participates to the chemical evolution of the interstellar medium, enriching it exclusively in H- and He-burning products. In particular, metal poor fast rotating stars may play a key role for explaining the origin of the peculiar abundance pattern observed at the surface of the extremely metal-poor C-rich stars, for explaining the chemical inhomogeneities observed in globular clusters, and the presence of stars in $ω$ Cen with a very high helium content .

description: Let (G_i | i in I) be a family of groups, let F be a free group, and let G = F *(*I G_i), the free product of F and all the G_i. Let FF denote the set of all finitely generated subgroups H of G which have the property that, for each g in G and each i in I, H \cap G_i^{g} = {1}. By the Kurosh Subgroup Theorem, every element of FF is a free group. For each free group H, the reduced rank of H is defined as r(H) = max{rank(H) -1, 0} in \naturals \cup {\infty} \subseteq [0,\infty]. To avoid the vacuous case, we make the additional assumption that FF contains a non-cyclic group, and we define sigma := sup{r(H\cap K)/(r(H)r(K)) : H, K in FF and r(H)r(K) \ne 0}, sigma in [1,\infty]. We are interested in precise bounds for sigma. In the special case where I is empty, Hanna Neumann proved that sigma in [1,2], and conjectured that sigma = 1; almost fifty years later, this interval has not been reduced. With the understanding that \infty/(\infty -2) = 1, we define theta := max{|L|/(|L|-2) : L is a subgroup of G and |L| > 2}, theta in [1,3]. Generalizing Hanna Neumann's theorem, we prove that sigma in [theta, 2 theta], and, moreover, sigma = 2 theta if G has 2-torsion. Since sigma is finite, FF is closed under finite intersections. Generalizing Hanna Neumann's conjecture, we conjecture that sigma = theta whenever G does not have 2-torsion.

These effects systematically showed the following sequence for Tc and the a-axis: the SWCNT doped wire < the MWshortCNT doped wire < the MWlongCNT doped wire < un-doped wire, while Jc(B) followed the sequence of the SWCNT doped wire > the MWshortCNT doped wire > the MWlongCNT doped wire > un-doped wire. A dominating mechanism behind all these findings is the level of C substitution for B in the lattice. The best Jc(B) and Hc2 were obtained on SWCNT doped wire because the level of C substitution for B in this wire is higher than all others.

description: A reliable and efficient computation of the entire single-particle spectrum of correlated molecules is an outstanding challenge in the field of quantum chemistry, with standard density functional theory approaches often giving an inadequate description of excitation energies and gaps. In this work, we expand upon a recently-introduced approach which relies on a fully self-consistent many-body perturbation theory, coupled to a non-perturbative truncation of the effective dynamics at each step. We show that this yields a low-scaling and accurate method across a diverse benchmark test set, capable of treating moderate levels of strong correlation effects, and detail an efficient implementation for applications up to $\sim1000$ orbitals on parallel resources. We then use this method to characterise the spectral properties of the artemisinin anti-malarial drug molecule, resolving discrepancies in previous works concerning the active sites of the lowest energy fundamental excitations of the system.

description: The channel $D_s^+\to p\bar n$ is the only kinematically allowed baryonic D decay. It proceeds solely through the W-annihilation topology. Hence, a recent observation of this mode by CLEO will shed light on the dynamics of W-annihilation. At the short-distance level, its branching ratio is very small, of order $10^{-6}$, owing to chiral suppression. It receives long-distance contributions through final-state scattering of the leading tree and color-suppressed amplitudes. Assuming that the long-distance enhancement of W-annihilation in the baryonic D decay is similar to that in the mesonic $D_s^+$ decay, where the latter can be obtained from the analysis of the diagrammatic approach, we find that $D_s^+\to p\bar n$ becomes visible. The observation of this baryonic D decay implies the dynamical enhancement of the W-annihilation topology in the $D_s^+$ decay.

description: The aim of this study is to examine and analyze the institutional context of freedom of religion or belief, as it has been historically transformed at a national and international level. The evolution of the respective legal and jurisprudential framework are in the main scope of our interest as they reflect the cultural, social, economic and political situation of any given time. Within this context we will endeavor to assess all relevant restrictions to freedom of religion or belief imposed at an EU and national level. In the same vein, special reference is made to the role of Islam in Greece as well as to the Muslim minority of Western Thrace. Historical and national variables have made a significant impact on the treatment of the Muslim minority and have also raised important concerns. To this end, recent massive refugee flows, especially from countries with strong Muslim ties, as well as the integration of the “New Islam” in Greece remain a challenge that the legislator has to face in a constantly and rapidly changing environment

An investigation of possible phytoplankton seeding in the Strait of Georgia from Nanoose Bay
Creators: name: Ianson, Debby
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the possibility of bays providing the seed population for the spring phytoplankton bloom to larger adjacent bodies of water via advective transport. The study area was Nanoose Bay, Vancouver Island and the adjacent region of the Strait of Georgia. In 1992 and 1993 data were collected 2-3 times weekly and a mooring with an array of 5 current meters was placed at the mouth of the bay during the 1992 study. Interannual variability was tremendous. In 1992 seeding from Nanoose Bay was not possible as the net transport was into the bay at the surface and middle depths. The influence of the Fraser River seemed to dominate as low density water with high silicate concentrations was present at the surface and density profiles were generally well stratified. Although nutrients were not limiting and light availability appeared high, phytoplankton concentrations were low until March 5 when they began to increase and a bloom occurred. It is suggested that horizontal advection and flushing of the bay were responsible for suppressing a bloom prior to March 5 in 1992. In 1993 phytoplankton concentrations were high inside the bay from the beginning of February onward. In the Strait no periods of high phytoplankton concentration occurred although there were two small increases which appear to be due to advective transport, although it is possible that the first was due to reduced wind mixing. It is suggested that seeding of the Strait from Nanoose Bay was possible in this year, although it is also possible that seeding occurred from other locations depending on time and conditions. The conservation equation for a scalar was used to investigate advective transport as balanced by biological sources and sinks. With no current measurements available in 1993, estimates were made from the above equation and compared to wind direction in the Strait and density changes at the mouth of the bay. In 1993 profiles were well mixed with respect to 1992 and overall salinity was higher. It is suggested that light was usually limiting to phytoplankton growth in the Strait due to vertical mixing throughout the study, while in the bay the depth of the water column limited vertical mixing thus allowing phytoplankton to bloom. To continue experiments of this type it is suggested that daily sampling be done as temporal changes can occur quickly. As evidenced from the 1993 data, spatial resolution is also valuable. Current measurements are necessary and their absence in the 1993 data set was unfortunate. It is suggested that drogues may be useful for measuring currents. They could be used to attempt to track phytoplankton when concentrations begin to increase.

description: A Kohn-Sham density functional approach has recently been developed for the fractional quantum Hall effect, which maps the strongly interacting electrons into a system of weakly interacting composite fermions subject to an exchange correlation potential as well as a density dependent gauge field that mimics the "flux quanta" bound to composite fermions. To get a feel for the role of various terms, we study the behavior of the self-consistent solution as a function of the strength of the exchange correlation potential, which is varied through an {\it ad hoc} multiplicative factor. We find that a crystal phase is stabilized when the exchange correlation interaction is sufficiently strong relative to the composite-fermion cyclotron energy. Various properties of this crystal are examined.

However, the algorithm uses randomly sampled matrices to define the underlying recurrent neural network and has a multitude of metaparameters that must be optimized. Recent results demonstrate the equivalence of reservoir computing to nonlinear vector autoregression, which requires no random matrices, fewer metaparameters, and provides interpretable results. Here, we demonstrate that nonlinear vector autoregression excels at reservoir computing benchmark tasks and requires even shorter training data sets and training time, heralding the next generation of reservoir computing.

description: We present results for the spin-1 color-spin locking phase (CSL) using a NJL-type model in two flavor quark matter for compact stars applications. The CSL condensate is flavor symmetric and therefore charge and color neutrality can easily be satisfied. We find small energy gaps ~1 MeV, which make the CSL matter composition and the EoS not very different from the normal quark matter phase. We keep finite quark masses in our calculations and obtain no gapless modes that could have strong consequences in the late cooling of neutron stars. Finally, we show that the region of the phase diagram relevant for neutron star cores, when asymmetric flavor pairing is suppressed, could be covered by the CSL phase.

description: We dynamically analyze our experimental results on the motion sensitive spiking H1 neuron of the fly's visual system. We find that the fly uses an alphabet composed of a few letters to encode the information contained in the stimulus. The {\em alphabet dynamics} is multifractal both with and without stimulus, though the multifractality increases with the stimulus entropy. This is in sharp contrast to models generating independent spike-intervals, whose dynamics is monofractal.

Discovery and modelling of broad-scale plasma lensing in black-widow pulsar J2051$-$0827

description: We report on an unusually bright observation of PSR J2051$-$0827 recorded during a regular monitoring campaign of black-widow pulsar systems with the Effelsberg 100-m telescope. Through fortunate coincidence, a particularly bright scintillation maximum is simultaneous with the eclipse by the companion, enabling precise measurements of variations in the flux density, dispersion measure (DM), and scattering strength throughout the eclipse. The flux density is highly variable throughout the eclipse, with a peak 1.7 times the average away from the eclipse, and yet does not significantly decrease on average. We recover the flux density variations from the measured DM variations using geometric optics, with a relative velocity as the only free parameter. We measure an effective velocity of (470 $\pm$ 10) km/s, consistent with the relative orbital motion of the companion, suggesting that the outflow velocity of the lensing material is low, or is directly along the line of sight. The 2 per cent uncertainty on the effective velocity is a formal error; systematics related to our current model are likely to dominate, and we detail several extensions to the model to be considered in a full treatment of lensing. This is a demonstration of the causal link between DM and lensing; the flux density variations can be predicted directly through the derivatives of DM. Going forward, this approach can be applied to investigate the dynamics of other eclipsing systems, and to investigate the physical nature of scintillation and lensing in the ionized interstellar medium.

description: In the analysis of large-scale network data, a fundamental operation is the comparison of observed phenomena to the predictions provided by null models: when we find an interesting structure in a family of real networks, it is important to ask whether this structure is also likely to arise in random networks with similar characteristics to the real ones. A long-standing challenge in network analysis has been the relative scarcity of reasonable null models for networks; arguably the most common such model has been the configuration model, which starts with a graph $G$ and produces a random graph with the same node degrees as $G$. This leads to a very weak form of null model, since fixing the node degrees does not preserve many of the crucial properties of the network, including the structure of its subgraphs. Guided by this challenge, we propose a new family of network null models that operate on the $k$-core decomposition. For a graph $G$, the $k$-core is its maximal subgraph of minimum degree $k$; and the core number of a node $v$ in $G$ is the largest $k$ such that $v$ belongs to the $k$-core of $G$. We provide the first efficient sampling algorithm to solve the following basic combinatorial problem: given a graph $G$, produce a random graph sampled nearly uniformly from among all graphs with the same sequence of core numbers as $G$. This opens the opportunity to compare observed networks $G$ with random graphs that exhibit the same core numbers, a comparison that preserves aspects of the structure of $G$ that are not captured by more local measures like the degree sequence. We illustrate the power of this core-based null model on some fundamental tasks in network analysis, including the enumeration of networks motifs.
The impact of bound states on similarity renormalization group transformations

description: We study a simple class of unitary renormalization group transformations governed by a parameter f in the range [0,1]. For f=0, the transformation is one introduced by Wegner in condensed matter physics, and for f=1 it is a simpler transformation that is being used in nuclear theory. The transformation with f=0 diagonalizes the Hamiltonian but in the transformations with f near 1 divergent couplings arise as bound state thresholds emerge. To illustrate and diagnose this behavior, we numerically study Hamiltonian flows in two simple models with bound states: one with asymptotic freedom and a related one with a limit cycle. The f=0 transformation places bound-state eigenvalues on the diagonal at their natural scale, after which the bound states decouple from the dynamics at much smaller momentum scales. At the other extreme, the f=1 transformation tries to move bound-state eigenvalues to the part of the diagonal corresponding to the lowest momentum scales available and inevitably diverges when this scale is taken to zero. We analyze the shift mechanism analytically in a 3x3 matrix model, which displays the essense of this RG behavior.

Compass orientation in migrating Fraser River sockeye salmon
Creators: name: Dat, Claire Germaine
Publisher: name: University of British Columbia
Year: 2009

description: Three numerical models were used to investigate whether compass orientation is an effective guidance mechanism for sockeye salmon migrating to the Fraser River from the open ocean. Daily surface ocean currents, simulated by the Ocean Surface Currents Simulations (OSCURS) model, were used in each model to test the influence of currents on the return oceanic migration of the Fraser River sockeye salmon. The high seas tagging and coastal recovery data of the Fraser River sockeye salmon were used for the migration simulations. The Fraser River sockeye salmon were shown to move in a northeastward direction during the first phase of their oceanic return migration and in a southeastward direction during the second phase of their migration. The surface daily currents were shown to increase the speed of the homeward migrating sockeye salmon. Most importantly, compass orientation alone was shown to be a possible orientation mechanism for the Fraser River sockeye salmon.
Coherent and incoherent processes and the LPM effect in oriented single crystals at high-energy

description: The process of radiation from high-energy electron and electron-positron pair production by a photon in oriented single crystal is considered using the method which permits inseparable consideration of both coherent and incoherent mechanisms of photon emission from an electron and of pair creation by a photon and includes the action of field of axis (or plane) as well as the multiple scattering of radiating electron or particles of the created pair (the Landau-Pomeranchuk-Migdal (LPM) effect). The total intensity of radiation and total probability pair creation are calculated. The theory, where the energy loss of projectile has to be taken into account, and found probabilities of pair creation agree quite satisfactory with available CERN data. From obtained results it follows that multiple scattering appears only for relatively low energy of radiating electron or a photon, while at higher energies the field action excludes the LPM effect.

description: We study aspects of black holes near the Hagedorn temperature. The large dimension expansion introduced by Soda, Emparan, Grumiller and Tanabe connects them to the well studied two dimensional black hole based on $SL(2)_k/U(1)$. This allows us to explore black holes at string scale temperatures. We argue that the black hole can surpass the Hagedorn temperature, but at a somewhat larger temperature it is likely to turn over to a highly excited string.

description: After introducing the notion of BPS preons as the basic constituents of M-theory, we discuss the recent negative results in the search for solutions of the D=10 and D=11 supergravity equations preserving 31/32 supersymmetries i.e., of preonic solutions. The absence of these supergravity preonic solutions may point out to a pure quantum nature of BPS preons, manifesting itself in the need of incorporating quantum (stringy/M-theoretic) corrections to the supergravity equations.
