description: We discuss the prospects of gravitational lensing of gravitational waves (GWs) coming from core-collapse supernovae (CCSN). As the CCSN GW signal can only be detected from within our own Galaxy and the local group by current and upcoming ground-based GW detectors, we focus on microlensing. We introduce a new technique based on analysis of the power spectrum and association of peaks of the power spectrum with the peaks of the amplification factor to identify lensed signals. We validate our method by applying it on the CCSN-like mock signals lensed by a point mass lens. We find that the lensed and unlensed signal can be differentiated using the association of peaks by more than one sigma for lens masses M$_{\rm L} {>} 150{\rm M}_{\odot}$. We also study the correlation integral between the power spectra and corresponding amplification factor. This statistical approach is able to differentiate between unlensed and lensed signals for lenses as small as M$_{\rm L} {\sim} 15{\rm M}_{\odot}$. Further, we demonstrate that this method can be used to estimate the mass of a lens in case the signal is lensed. The power spectrum based analysis is general and can be applied to any broad band signal and is especially useful for incoherent signals.

description: We study the quantum dynamics of a one-dimensional spin-1/2 anisotropic XY model in a transverse field when the transverse field or the anisotropic interaction is quenched at a slow but uniform rate. The two quenching schemes are called transverse and anisotropic quenching respectively. Our emphasis in this paper is on the anisotropic quenching scheme and we compare the results with those of the other scheme. In the process of anisotropic quenching, the system crosses all the quantum critical lines of the phase diagram where the relaxation time diverges. The evolution is non-adiabatic in the time interval when the parameters are close to their critical values, and is adiabatic otherwise. The density of defects produced due to non-adiabatic transitions is calculated by mapping the many-particle system to an equivalent Landau-Zener problem and is generally found to vary as $1/\sqrtτ$, where $τ$ is the characteristic time scale of quenching, a scenario that supports the Kibble-Zurek mechanism. Interestingly, in the case of anisotropic quenching, there exists an additional non-adiabatic transition, in comparison to the transverse quenching case, with the corresponding probability peaking at an incommensurate value of the wave vector. In the special case in which the system passes through a multi-critical point, the defect density is found to vary as $1/τ^{1/6}$. The von Neumann entropy of the final state is shown to maximize at a quenching rate around which the ordering of the final state changes from antiferromagnetic to ferromagnetic.

description: We study the effect of chargeable monomers on the conformation of dendrimers of low generation by computer simulations, employing bare Coulomb interactions. The presence of the latter leads to an increase in size of the dendrimer due to a combined effect of electrostatic repulsion and the presence of counterions within the dendrimer, and also enhances a shell-like structure for the monomers of different generations. In the resulting structures the bond-length between monomers, especially near the center, will increase to facilitate a more effective usage of space in the outer-regions of the dendrimer.

description: This paper reviews the role of expert judgement to support reliability assessments within the systems engineering design process. Generic design processes are described to give the context and a discussion is given about the nature of the reliability assessments required in the different systems engineering phases. It is argued that, as far as meeting reliability requirements is concerned, the whole design process is more akin to a statistical control process than to a straightforward statistical problem of assessing an unknown distribution. This leads to features of the expert judgement problem in the design context which are substantially different from those seen, for example, in risk assessment. In particular, the role of experts in problem structuring and in developing failure mitigation options is much more prominent, and there is a need to take into account the reliability potential for future mitigation measures downstream in the system life cycle. An overview is given of the stakeholders typically involved in large scale systems engineering design projects, and this is used to argue the need for methods that expose potential judgemental biases in order to generate analyses that can be said to provide rational consensus about uncertainties. Finally, a number of key points are developed with the aim of moving toward a framework that provides a holistic method for tracking reliability assessment through the design process.

Foraging behaviour of captive black-tailed deer (Odocoileus hemionus columbianus)
Creators: name: Gillingham, Michael Patrick
Publisher: name: University of British Columbia
Year: 2010

description: A review of the literature on black-tailed deer (Odocoileus hemionus columbianus Richardson) feeding habits reveals considerable variation among animals, locations, and seasons. Processes affecting food selection, however, are poorly understood. Optimal foraging theory was explored as a means of predicting deer foraging behaviour and diet breadth. Because of complex constraints and objectives involved in predicting diet selection, food preference was determined under ad libitum conditions. Feeding behaviour of two deer was studied in a 0.5-ha enclosure to examine the effects of density and distribution of their preferred foods on diet selection. When deer had to search for food, diet selection remained the same as that under ad libitum conditions as long as preferred food was abundant. Deer nearly exhausted their highly preferred food before switching to lower ranked foods. This switch was gradual, as deer continued to search for preferred food. The amount of preferred food already eaten during a trial was positively correlated with the time that animals would continue searching before switching to lower-ranked foods. Switching was related to the amount and type of food encountered and not to the amount of food in the pen. Dispersion of the preferred food (clumped versus unclumped) had no significant effect on the amount of food eaten, but did significantly influence the types of food encountered by one of the two animals. Both animals became more efficient (intake per distance travelled) at finding preferred foods with increasing experience with a specific distribution of food. Animals increased their efficiency of finding apples by repeating searching patterns which had been effective during previous trials. Performance was poor, however, when distributions were changed. When preferred food was abundant, platforms containing preferred food were not always completely cleared of food the first time a platform was visited. Intake rates of non-preferred foods tended to increase with declining abundance of preferred food. This increase was not caused by changes in the amount of non-preferred food eaten at feeding stations, but rather by the rate at which non-preferred feeding stations were visited. The influence of intraspecific plant variation on food habit studies and the utility of preference indices are discussed. I conclude that foraging bouts are highly dynamic and that some foraging questions may not be adequately answered if this internal variation is ignored.

description: We use linear perturbation theory to study perturbations in dynamical dark energy models. We compare quintessence and tachyonic dark energy models with identical background evolution. We write the corresponding equations for different models in a form that makes it easier to see that the two models are very hard to distinguish in the linear regime, especially for models with $(1 + w) \ll 1$. We use Cosmic Microwave Background data and parametric representations for the two models to illustrate that they cannot be distinguished for the same background evolution with existing observations. Further, we constrain tachyonic models with the Planck data. We do this analysis for exponential and inverse square potentials and find that the intrinsic parameters of the potentials remain very weakly constrained. In particular, this is true in the regime allowed by low redshift observations.

description: Superconducting excitations -- Bogoliubov quasiparticles -- are the quantum mechanical mixture of negatively charged electron (-e) and positively charged hole (+e). We propose a new observable for Angular Resolved Photoemission Spectroscopy (ARPES) studies that is the manifestation of the particle-hole entanglement of the superconducting quasiparticles. We call this observable a {\em Bogoliubov angle}. This angle measures the relative weight of particle and hole amplitude in the superconducting (Bogoliubov) quasiparticle. We show how this quantity can be measured by comparing the ratio of spectral intensities at positive and negative energies.

description: We present the kinematics of a sample of bipolar planetary nebulae (PNe) which cover a wide range of observed morphologies and collimation degrees, from bipolar PNe with a marked equatorial ring and wide lobes to highly collimated objects. We use an empirical model in order to derive the expansion velocity, collimation degree, and inclination angle of the PN with respect to the plane of the sky. The equatorial expansion velocities measured in the objects in our sample are always in the low to medium range (3-16km/s),while their polar expansion velocities range from low to very high (18-100 km/s). None of the objects in our sample, even those that show an extreme collimation degree, seem to be (kinematically) younger than ~1000 yr. We compare our results with the state-of-the-art theoretical models for the formation of bipolar PNe. We find good agreement between the observed expansion velocities and numerical models that use magnetic fields with stellar rotation as collimation mechanism.

description: Quantum states with nonlinear squeezing are a necessary resource for deterministic implementation of high-order quadrature phase gates that are, in turn, sufficient for advanced quantum information processing. We demonstrate that this class of states can be deterministically prepared by employing a single Kerr gate accompanied by suitable Gaussian processing. The required Kerr coupling depends on the energy of the initial system and can be made arbitrarily small. We also employ numerical simulations to analyze the effects of imperfections and to show to which extent can they be neglected.

description: We report on the preparation and characterization of single crystal gamma phase NaxCoO2 with 0.25 < x < 0.84 using a non-aqueous electrochemical chronoamperemetry technique. By carefully mapping the overpotential versus x (for x < 0.84), we find six distinct stable phases with Na levels corresponding to x ~ 0.75, 0.71, 0.50, 0.43, 0.33 and 0.25. The composition with x ~0.55 appears to have a critical Na concentration which separates samples with different magnetic behavior as well as different Na ion diffusion mechanisms. Chemical analysis of an aged crystal reveals different Na ion diffusion mechanisms above and below x_c ~ 0.53, where the diffusion process above x_c has a diffusion coefficient about five times larger than that below x_c. The series of crystals were studied with X-ray diffraction, susceptibility, and transport measurements. The crystal with x = 0.5 shows a weak ferromagnetic transition below T=27 K in addition to the usual transitions at T = 51 K and 88 K. The resistivity of the Curie-Weiss metallic Na0.71CoO2 composition has a very low residual resistivity, which attests to the high homogeneity of the crystals prepared by this improved electrochemical method. Our results on the various stable crystal compositions point to the importance of Na ion ordering across the phase diagram.

description: The crystal structures of the triangular lattice, layered anhydrous alums KCr(SO4)2, RbCr(SO4)2 and KAl(SO4)2 are characterized by X-ray and neutron powder diffraction at temperatures between 1.4 and 773 K. The compounds all crystallize in the space group P-3, with octahedral coordination of the trivalent cations. In all cases, small amounts of disorder in the stacking of the triangular layers of corner sharing MO6 octahedra and SO4 tetrahedra is seen, with the MO6-SO4 network rotated in opposite directions between layers. The electron diffraction study of KCr(SO4)2 supports this model, which on average can be taken to imply trigonal prismatic coordination for the M3+ ions; as was previously reported for the prototype anhydrous alum KAl(SO4)2. The temperature dependent magnetic susceptibilities for ACr(SO4)2 (A = K,Rb,Cs) indicate the presence of predominantly ferromagnetic interactions. Low temperature powder neutron diffraction reveals that the magnetic ordering is ferromagnetic in-plane, with antiferromagnetic ordering between planes below 3 K.

description: We discuss a mechanism which generates a mass term for a scalar field in an expanding universe. The mass of this field turns out to be generated by the cosmological constant and can be naturally small if protected by a conformal symmetry which is however broken in the gravitational sector. The mass is comparable today to the Hubble time. This scalar field could thus impact our universe today and for example be at the origin of a time variation of the couplings and masses of the parameters of the standard model.

description: The aim of the present thesis was the study of the of law governing the organization of retail pharmacy businesses as corporations in Greece and UK. Initially, we briefly presented the ways of organizing business activities and the distinctions between corporate types encountered in the United Kingdom. Further to this, an analysis was conducted of the legislative framework that governs the organization of retail sale of pharmaceutical products in the United Kingdom, as well as the role played by the professional pharmacist in pharmacies operating as legal entities. We also discussed the different categories of commercial companies that could be incorporated under Greek law. Another aim of this study was the practice of retail sale of pharmaceutical products by both pharmacists and non-pharmacists. We provided a detailed discussion of the restrictions governing the organization of pharmacies as corporations under Greek law. Additionally, we examined whether the operation of private pharmacies exclusively by individuals with a pharmacy degree is in compliance with EU law. We made a comparison of Greece's more conservative legislative framework and the United Kingdom's more liberal legislative framework regarding the organization of retail pharmacy businesses as corporations.

description: Based on the SDSS catalog, we have found new close quasar-galaxy pairs. Quasars projected onto the halos of nearer galaxies are encountered among the multitude of quasars observed at various distances from us. Among them there are quasars that are close to the galaxies not only in angular separation, but also in redshift. Such quasar-galaxy pairs are called close pairs. We developed further the hypothesis that such pairs appear, because the fluxer on the nucleus of the more distant galaxy passes through halo globular clusters of the nearer galaxy,resulting in magnification and splitting of the image of the source that we interpret as a quasar. To corroborate this hypothesis, we analyzed the distribution of quasars in the plane of the halos of these galaxies. The quasars from close pairs were found to follow the density profile of globular clusters in the halos of elliptical and spiral galaxies with slopes of -1.5 and -2.4 for elliptical and spiral galaxies, respectively. This suggests that quasars do not appear near galaxies by chance and that quasars are associated with galaxies via halo globular clusters.

description: Optimization of materials performance for specific applications often requires balancing multiple aspects of materials functionality. Even for the cases where generative physical model of material behavior is known and reliable, this often requires search over multidimensional parameter space to identify low-dimensional manifold corresponding to required Pareto front. Here we introduce the multi-objective Bayesian Optimization (MOBO) workflow for the ferroelectric/anti-ferroelectric performance optimization for memory and energy storage applications based on the numerical solution of the Ginzburg-Landau equation with electrochemical or semiconducting boundary conditions. MOBO is a low computational cost optimization tool for expensive multi-objective functions, where we update posterior surrogate Gaussian process models from prior evaluations, and then select future evaluations from maximizing an acquisition function. Using the parameters for a prototype bulk antiferroelectric (PbZrO3), we first develop a physics-driven decision tree of target functions from the loop structures. We further develop a physics-driven MOBO architecture to explore multidimensional parameter space and build Pareto-frontiers by maximizing two target functions jointly: energy storage and loss. This approach allows for rapid initial materials and device parameter selection for a given application and can be further expanded towards the active experiment setting. The associated notebooks provide both the tutorial on MOBO and allow to reproduce the reported analyses and apply them to other systems (https://github.com/arpanbiswas52/MOBO_AFI_Supplements).

description: The near-threshold behavior of the ppbar invariant mass spectrum from the J/psi -> omega ppbar decay reported recently by the BES Collaboration is analyzed. Contrary to the statement made by the BES Collaboration itself our study demonstrates that there is indeed a noticeable enhancement in the ppbar invariant mass spectrum near threshold. Moreover, this enhancement is nicely reproduced by the final state interaction in the relevant 11S0 ppbar partial wave as given by the Julich nucleon--antinucleon model. Therefore, and again contrary to the statement by the BES Collaboration, their new data on J/psi -> omega ppbar decay in fact strongly support the FSI interpretation of the ppbar enhancement, seen also in other decay reactions.

description: In this article, we study the Sagnac effect for spin-$1/2$ particles through local Wigner rotations according to the framework developed by [H. Terashima and M. Ueda, Phys. Rev. A 69, 032113 (2004)]. Since the spin of the particle plays the role of a quantum `clock', as the quanton moves in a superposed path it gets entangled with the momentum (or the path), and this will cause the interferometric visibility to drop, since there is a difference in proper time elapsed along the two trajectories, which is known as the Sagnac time delay.

description: Here we demonstrate that adding a chemo-mechanical polishing (CMP) procedure to conventional photolithography, a silica microdisk with ultra-high quality factors ($>10^8$) can be fabricated. By comparing with the intrinsic optical quality factor (Q) measured at 970~nm, we observe that due to the significantly reduced surface roughness, at 1550~nm wavelength the water molecule absorption at the cavity surface supersedes Rayleigh scattering as the dominant factor for Q degradation.

Predictions for local PNG bias in the galaxy power spectrum and bispectrum and the consequences for $f_{\rm NL}$ constraints

description: We use hydrodynamical separate universe simulations with the IllustrisTNG model to predict the local primordial non-Gaussianity (PNG) bias parameters $b_ϕ$ and $b_{ϕδ}$, which enter at leading order in the galaxy power spectrum and bispectrum. This is the first time that $b_{ϕδ}$ is measured from either gravity-only or galaxy formation simulations. For dark matter halos, the popular assumption of universality overpredicts the $b_{ϕδ}(b_1)$ relation in the range $1 \lesssim b_1 \lesssim 3$ by up to $Δb_{ϕδ} \sim 3$ ($b_1$ is the linear density bias). The adequacy of the universality relation is worse for the simulated galaxies, with the relations $b_ϕ(b_1)$ and $b_{ϕδ}(b_1)$ being generically redshift-dependent and very sensitive to how galaxies are selected (we test total, stellar and black hole mass, black hole mass accretion rate and color). The uncertainties on $b_ϕ$ and $b_{ϕδ}$ have a direct, often overlooked impact on the constraints of the local PNG parameter $f_{\rm NL}$, which we study and discuss. For a survey with $V = 100{\rm Gpc}^3/h^3$ at $z=1$, uncertainties $Δb_ϕ \lesssim 1$ and $Δb_{ϕδ} \lesssim 5$ around values close to the fiducial can yield relatively unbiased constraints on $f_{\rm NL}$ using power spectrum and bispectrum data. We also show why priors on galaxy bias are useful even in analyses that fit for products $f_{\rm NL} b_ϕ$ and $f_{\rm NL} b_{ϕδ}$. The strategies we discuss to deal with galaxy bias uncertainties can be straightforwardly implemented in existing $f_{\rm NL}$ constraint analyses (we provide fits for some of the bias relations). Our results motivate more works with galaxy formation simulations to refine our understanding of $b_ϕ$ and $b_{ϕδ}$ towards improved constraints on $f_{\rm NL}$.

Trying to make a life : the historical political economy of Kitsumkalum
Creators: name: McDonald, James Andrew

description: Anthropological inquiries into the human condition have long been tempered with a concern for the difficulties experienced by non-Western societies faced with prolonged contact with the expanding Western social systems. In economic anthropology, studies of contemporary tribal and peasant societies have turned to the literature on development and underdevelopment to explain the features and processes that are associated with that contact. This dissertation is the result of such research into the social and economic problems on the Northwest Coast. The work examines the history and ethhography of the Tsimshian Indians to determine the underlying social forces that led to and still maintain the underdevelopment of the social and economic potential of Tsimshian groups. Particular attention is given to the form and dynamics of the Tsimshian economy, of the regional expression of the expanding world market economy, and the relations between the two. The dissertation thus explores the socioeconomic aspects of the interlock between Indian development and the evolving development of capital. The Tsimshian village of Kitsumkalum was the focus of the inquiry. Using its history, I document how the changes which brought about an economic reversal for the native people were at the same time favourable to the establishment and growth of industrial capital in the region. Two sets of factors are critical for understanding.this shift: (1) new forms of property which, through government intervention, transferred ownership and control of the factors of production to the industrialists, and in the process redefined the resources, technology and labour in terms consistent with the development of capital; (2) the diversion of Tsimshian resources, technology and labour out of traditional production into the modern economy, where they were transformed and ultimately became dependent on the vagaries of a global market in which the Tsimshians had little or no control. The specific information in the dissertation explains how these processes occurred, how the independence of the old political economy was undermined, how an ostensibly "peaceful penetration" of the area occurred as a result, and how the Tsimshian responded by alternately accommodating and resisting the situation.

description: Recent advancement in quantitative liquid-jet photoelectron spectroscopy enables the accurate determination of the absolute-scale electronic energetics of liquids and species in solution. Our major objective is the determination of the absolute lowest-ionization energy of liquid water which is found to vary upon solute addition, and depends on the solute concentration. We discuss two prototypical aqueous salt solutions, NaI(aq) and tetrabutylammonium iodide, TBAI(aq), with the latter being a strong surfactant. Considerably different behavior is revealed: In the NaI(aq) solutions, water's 1b1 energy increases by 300 meV upon increasing the concentration near-saturation concentrations, whereas for TBAI the energy decreases by about 0.7 eV upon formation of a surface layer. The solute-induced effects on the solute binding energies are quantified as well, as inferred from concentration-dependent energy shifts of the I- 5p peak energy. For NaI(aq), an almost identical I- 5p shift is found as for the water 1b1 binding energy, with a larger shift occurring in the opposite direction for the TBAI(aq) solution. We show that this result in NaI(aq) can be primarily assigned to a change of water's electronic structure in the solution bulk. In contrast, apparent changes of the 1b1 energy for TBAI(aq) can be related to changes of the solution work function which could arise from surface molecular dipoles. Furthermore, for both of the solutions studied here, the measured water 1b1 binding energies can be correlated with the extensive solution molecular structure changes occurring at high salt concentrations, where in the case of NaI(aq), too few water molecules exist to hydrate individual ions and the solution adopts a crystalline-like phase. We also comment on the concentration-dependent shape of the 3a1 orbital of liquid water which is a sensitive signature of water-water hydrogen bond interactions.

description: The rotational constants and the nitrogen nuclear quadrupole coupling constants of cis-3-aminophenol and trans-3-aminophenol are determined using Fourier-transform microwave spectroscopy. We examine several $J=2\leftarrow{}1$ and $1\leftarrow{}0$ hyperfine-resolved rotational transitions for both conformers. The transitions are fit to a rigid rotor Hamiltonian including nuclear quadrupole coupling to account for the nitrogen nucleus. For cis-3-aminophenol we obtain rotational constants of A=3734.930 MHz, B=1823.2095 MHz, and C=1226.493 MHz, for trans-3-aminophenol of A=3730.1676 MHz, B=1828.25774 MHz, and C=1228.1948 MHz. The dipole moments are precisely determined using Stark effect measurements for several hyperfine transitions to $μ_a=1.7735$ D, $μ_b=1.5195$ D for cis-3-aminophenol and $μ_a=0.5563$ D, $μ_b=0.5376$ D for trans-3-aminophenol. Whereas the rotational constants and quadrupole coupling constants do not allow to determinate the absolute configuration of the two conformers, this assignment is straight-forward based on the dipole moments. High-level \emph{ab initio} calculations (B3LYP/6-31G^* to MP2/aug-cc-pVTZ) are performed providing error estimates of rotational constants and dipole moments obtained for large molecules by these theoretical methods.

description: Over the past decade, wind energy has gained more attention in the world. However, owing to its indirectness and volatility properties, wind power penetration has increased the difficulty and complexity in dispatching and planning of electric power systems. Therefore, it is needed to make the high-precision wind power prediction in order to balance the electrical power. For this purpose, in this study, the prediction performance of linear regression, k-nearest neighbor regression and decision tree regression algorithms is compared in detail. k-nearest neighbor regression algorithm provides lower coefficient of determination values, while decision tree regression algorithm produces lower mean absolute error values. In addition, the meteorological parameters of wind speed, wind direction, barometric pressure and air temperature are evaluated in terms of their importance on the wind power parameter. The biggest importance factor is achieved by wind speed parameter. In consequence, many useful assessments are made for wind power predictions.

description: We study evolution of gravitational perturbations of black strings. It is well known that for all wavenumber less than some threshold value, the black string is unstable against scalar type of gravitational perturbations, which is named the Gregory-Laflamme instability. Using numerical methods, we find the quasinormal modes and time-domain profiles of the black string perturbations in the stable sector and also show the appearance of the Gregory-Laflamme instability in the time domain. The dependence of the black string quasinormal spectrum and late time tails on such parameters as the wave vector and the number of extra dimensions is discussed. There is a numerical evidence that in the threshold point of instability the static solution of the wave equation is dominant. For wavenumbers slightly larger than the threshold value, in the region of stability, we see tiny oscillations with very small damping rate. While, for wavenumbers slightly smaller than the threshold value, in the region of the Gregory-Laflamme instability, we observe tiny oscillations with very small growth rate. We also find the level crossing of imaginary part of quasinormal modes between the fundamental mode and the first overtone mode, which accounts for the peculiar time domain profiles.
