The social geography of new age spirituality in Vancouver
Creators: name: Mills, Colin Ivor
Publisher: name: University of British Columbia
Year: 2009

description: It was expected that by the end of the twentieth-century, due to human achievement and technology, religion would be a mere fading memory in the minds and the history books of modernized western people. This has been expressed through the secularization thesis, which describes a “disenchantment” of western culture. Over the last ten years, however, there has been a growing movement seeking to re-enchant this culture by exploring and reconsidering religion, myth and spirituality. One of the most powerful expressions of this is popularly referred to as the New Age Movement. This thesis looks at the relationship between New Age and secularization theory, examining the reasons for an apparent turn away from secularization. By using Jacques Ellul’s interpretation of the history of the sacred, this thesis proposes that far from being a time of secularization, modernism ushered in an era where the sacred canopy of Christianity was replaced by a new sacred expression in the form of science and technology. In recent years, however, the perceived failure of modernism has generated a search for a new set of sacred expressions in western society. New Age and postmodernism are vehicles which people are using to initiate this search. Currently both phenomena are looking to three sources in order to recover meaning and control over life: the past and the distant, nature and the self. The theoretical challenge New Age and postmodernism represents to the secularization thesis is made concrete in the geography of the New Age Movement. This thesis makes a physical connection between the New Age and areas of gentrification, which contradicts the assumptions of the secularization thesis by proving that an area which should be highly secularized is in fact a place of spiritual exploration.

description: The tree-level amplitudes in $β$-deformed theory are studied from twistor string theory. We first show that a simple generalization of the proposal in hep-th/0410122 gives the correct results for all of the tree-level amplitudes to the first order of the deformation parameter $β$. Then we give a proposal to all orders of $β$ and show this matches the field theory. We also show the prescription using connected instantons and the prescription using disconnected instantons are equivalent in the deformed twistor string theory. The tree-level amplitudes in non-supersymmetric $γ$-deformed theory are also obtained in this framework. The tree-level purely gluonic amplitudes in theories with generic marginal deformations are also discussed in the twistor string theory side.

description: Killing-Yano (KY) two and three forms of a class of spherically symmetric space-times that includes the well-known Minkowski, Schwarzschild, Reissner-Nordstrom, Robertson-Walker and six different forms of de Sitter space-times as special cases are derived in a unified and exhaustive manner. It is directly proved that while the Schwarzschild and Reissner-Nordstrom space-times do not accept any KY 3-form and they accept only one 2-form, the Robertson-Walker space-time admits four KY 2-forms and only one KY 3-form. Maximal number of KY-forms are obtained for Minkowski and all known forms of de Sitter space-times. Complete lists comprising explicit expressions of KY-forms are given.

A GLIMPSE-based search for 6.7-GHz Methanol Masers and the lifetime of their spectral features

description: The University of Tasmania Mt Pleasant 26-m and Ceduna 30-m radio telescopes have been used to search for 6.7-GHz class II methanol masers towards two hundred GLIMPSE sources. The target regions were selected on the basis of their mid-infrared colours as being likely to be young high-mass star formation regions and are either bright at 8.0 micron, or have extreme [3.6]-[4.5] colour. Methanol masers were detected towards 38 sites, nine of these being new detections. The prediction was that approximately 20 new 6.7-GHz methanol masers would be detected within 3.5 arcmin of the target GLIMPSE sources, but this is the case for only six of the new detections. A number of possible reasons for the discrepancy between the predicted and actual number of new detections have been investigated. It was not possible to draw any firm conclusions as to the cause, but it may be because many of the target sources are at an evolutionary phase prior to that associated with 6.7-GHz methanol masers. Through comparison of the spectra collected as part of this search with those in the literature, the average lifetime of individual 6.7-GHz methanol maser spectral features is estimated to be around 150 years, much longer than is observed for 22-GHz water masers.

description: The progress witnessed within the field of quantum computing has been enabled by the identification and understanding of interactions between the state of the quantum bit (qubit) and the materials within its environment. Beginning with an introduction of the parameters used to differentiate various quantum computing approaches, we discuss the evolution of the key components that comprise superconducting qubits, where the methods of fabrication can play as important a role as the composition in dictating the overall performance. We describe several mechanisms that are responsible for the relaxation or decoherence of superconducting qubits and the corresponding methods that can be utilized to characterize their influence. In particular, the effects of dielectric loss and its manifestation through the interaction with two-level systems (TLS) are discussed. We elaborate on the methods that are employed to quantify dielectric loss through the modeling of energy flowing through the surrounding dielectric materials, which can include contributions due to both intrinsic TLS and extrinsic aspects, such as those generated by processing. The resulting analyses provide insight into identifying the relative participation of specific sections of qubit designs and refinements in construction that can mitigate their impact on qubit quality factors. Additional prominent mechanisms that can lead to energy relaxation within qubits are presented along with experimental techniques which assess their importance. We close by highlighting areas of future research that should be addressed to help facilitating the successful scaling of superconducting quantum computing.

description: The low emittance and small momentum spread of the proton and deuteron beams of the Cooler Synchrotron COSY combined with the high mass resolution of the COSY-11 detection system permit to study the creation of mesons in the nucleon-nucleon interaction down to the fraction of MeV with respect to the kinematical threshold. At such small excess energies, the ejectiles possess low relative momenta and are predominantly produced with the relative angular momentum equal to zero. Taking advantage of these conditions we have performed investigations aiming to determine the mechanism of the production of eta and eta' mesons in the collision of hadrons as well as the hadronic interaction of these mesons with nucleons and nuclei. In this proceedings we address the ongoing studies of the spin and isospin dependence for the production of the eta and eta' mesons in free and quasi-free nucleon-nucleon collisions. New results on the spin observables for the vec(p)p --> pp eta reaction, combined with the previously determined total cross section isospin dependence, reveal a statistically significant indication that the excitation of the nucleon to the S11(1535) resonance, the process which intermediates the production of the eta meson in the nucleon-nucleon interactions, is predominantly due to the exchange of the pi meson between the colliding nucleons.

description: Of the over 200 known extrasolar planets, 14 exhibit transits in front of their parent stars as seen from Earth. Spectroscopic observations of the transiting planets can probe the physical conditions of their atmospheres. One such technique can be used to derive the planetary spectrum by subtracting the stellar spectrum measured during eclipse (planet hidden behind star) from the combined-light spectrum measured outside eclipse (star + planet). Although several attempts have been made from Earth-based observatories, no spectrum has yet been measured for any of the established extrasolar planets. Here we report a measurement of the infrared spectrum (7.5--13.2 micron) of the transiting extrasolar planet HD209458b. Our observations reveal a hot thermal continuum for the planetary spectrum, with approximately constant ratio to the stellar flux over this wavelength range. Superposed on this continuum is a broad emission peak centered near 9.65 micron that we attribute to emission by silicate clouds. We also find a narrow, unidentified emission feature at 7.78 micron. Models of these ``hot Jupiter'' planets predict a flux peak near 10 micron, where thermal emission from the deep atmosphere emerges relatively unimpeded by water absorption, but models dominated by water fit the observed spectrum poorly.

Exact properties of an integrated correlator in $\mathcal{N}=4$ $SU(N)$ SYM

description: We present a novel expression for an integrated correlation function of four superconformal primaries in $SU(N)$ $\mathcal{N}=4$ SYM. This integrated correlator, which is based on supersymmetric localisation, has been the subject of several recent developments. The correlator is re-expressed as a sum over a two dimensional lattice that is valid for all $N$ and all values of the complex Yang-Mills coupling $τ$. In this form it is manifestly invariant under $SL(2,\mathbb{Z})$ Montonen-Olive duality. Furthermore, it satisfies a remarkable Laplace-difference equation that relates the $SU(N)$ to the $SU(N+1)$ and $SU(N-1)$ correlators. For any fixed value of $N$ the correlator is an infinite series of non-holomorphic Eisenstein series, $E(s;τ,\barτ)$ with $s\in \mathbb{Z}$, and rational coefficients. The perturbative expansion of the integrated correlator is asymptotic and the $n$-loop coefficient is a rational multiple of $ζ(2n+1)$. The $n=1$ and $n=2$ terms agree precisely with results determined directly by integrating the expressions in one- and two-loop perturbative SYM. Likewise, the charge-$k$ instanton contributions have an asymptotic, but Borel summable, series of perturbative corrections. The large-$N$ expansion of the correlator with fixed $τ$ is a series in powers of $N^{1/2-\ell}$ ($\ell\in \mathbb{Z}$) with coefficients that are rational sums of $E_s$ with $s\in \mathbb{Z}+1/2$. This gives an all orders derivation of the form of the recently conjectured expansion. We further consider 't Hooft large-$N$ Yang-Mills theory. The coefficient of each order can be expanded as a convergent series in $λ$. For large $λ$ this becomes an asymptotic series with coefficients that are again rational multiples of odd zeta values. The large-$λ$ series is not Borel summable, and its resurgent non-perturbative completion is $O(\exp(-2\sqrtλ))$.

description: The dynamics of small spheres, which are held by linear springs in a low Reynolds number shear flow at neighboring locations is investigated. The flow elongates the beads and the interplay of the shear gradient with the nonlinear behavior of the hydrodynamic interaction among the spheres causes in a large range of parameters a bifurcation to a surprising oscillatory bead motion. The parameter ranges, wherein this bifurcation is either super- or subcritical, are determined.

description: Increasing observations are becoming available about a relatively weak, but persistent, non-axisymmetric magnetic field co-existing with the dominant axisymmetric field on the Sun. It indicates that the non-axisymmetric magnetic field plays an important role in the origin of solar activity. A linear non-axisymmetric alpha2-Omega dynamo model is set up to discuss the characteristics of the axisymmetric m=0 and the first non-axisymmetric m=1 modes and to provide further the theoretical bases to explain the active longitude, flip-flop and other non-axisymmetric phenomena. The model consists of a updated solar internal differential rotation, a turbulent diffusivity varied with depth and an alpha-effect working at the tachocline in rotating spherical systems. The difference between the alpha2-Omega and the alpha-Omega models and the conditions to favor the non-axisymmetric modes with the solar-like parameters are also presented.

description: The paper begins by overviewing the basic facts on geometric exceptional collections. Then, we derive, for any coherent sheaf $\cF$ on a smooth projective variety with a geometric collection, two spectral sequences: the first one abuts to $\cF$ and the second one to its cohomology. The main goal of the paper is to generalize Castelnuovo-Mumford regularity for coherent sheaves on projective spaces to coherent sheaves on smooth projective varieties $X$ with a geometric collection $σ$. We define the notion of regularity of a coherent sheaf $\cF$ on $X$ with respect to $σ$. We show that the basic formal properties of the Castelnuovo-Mumford regularity of coherent sheaves over projective spaces continue to hold in this new setting and we show that in case of coherent sheaves on $\PP^n$ and for a suitable geometric collection of coherent sheaves on $\PP^n$ both notions of regularity coincide. Finally, we carefully study the regularity of coherent sheaves on a smooth quadric hypersurface $Q_n \subset \PP^{n+1}$ ($n$ odd) with respect to a suitable geometric collection and we compare it with the Castelnuovo-Mumford regularity of their extension by zero in $\PP^{n+1}$.

description: Using an online experiment, this study examines the hostile media phenomenon and how it affects the emotions and political behavior of the individuals concerning the debatable issue of climate change. It has been examined the self- efficacy and collective efficacy variables and their association with emotions and climate activism. Data from a web-based survey with a sample size of 432 participants were analyzed. Findings indicated that hostile media perception is positive associated with climate change activism. Also, the perceptions of bias and climate activism have proven to be both related with emotions. The belief of individual that is capable of engaging in climate change policies, known as self-efficacy offered unique positive association with intentions to engage in climate change-related political participation. The implications for science communication are discussed.

description: Estimation of unknown process parameters is critical in statistical process control/monitoring (SPC/M). Retrospective data is usually used to identify the process in-control state behavior in terms of estimating the process parameters. Practitioners analyze the retrospective data in order to handle out-of-control observations before estimating the parameters. However, chances to overlook some out-of-control observations do exist; in which case, the Phase I data is said to be contaminated. In this study, we aim to assess the impact of having contaminated retrospective data on the performance of the EWMA chart; assuming non-normal processes. Two distributions are considered; the t-distribution to represent a symmetric heavy-tailed distribution with two contamination scenarios, and the Gamma distribution to represent a skewed one. A weighted variance EWMA chart is used with the Gamma distribution to account for the skewness. Our results revealed that under the t-distribution a contamination with respect to the mean is more serious than a contamination with respect to the degrees of freedom. Under the gamma distribution, the estimation effect generally and contamination effect specifically are more serious on smaller shape parameter values (heavily skewed).
A policy framework for sustainable tourism: the case of Trinidad and Tobago
Creators: name: Bascombe, Philbert Anthony
Publisher: name: University of British Columbia
Year: 2009

description: International tourism is rapidly becoming the world's fastest growing industry. The industry has generated growth and investment in many countries. However, this growth has frequently been achieved at the expense of the human and physical environment in many countries, particularly in the developing world. These impacts have been manifested in the form of social, cultural and environmental degradation. Disillusionment with mass tourism and the problems associated with it have led many researchers and planners to question the past unplanned approach to tourism development. Organizations such as the World Tourism Organization and the Ecumenical Coalition on Third World Tourism (ECTWT) are calling for an "alternative tourism," broadly defined as a form of tourism which is consistent with social, cultural, economic and environmental values of destination areas. The case study outlines a policy framework for adopting an alternative approach to tourism development for one Commonwealth Caribbean country, Trinidad and Tobago. Implicit in this approach is the need to ensure that tourism development emphasizes community involvement, distributional equity, respect for local cultures, and protection and enhancement of the human and physical environment on which tourism is based. The general purpose of the case study is to make a contribution to the development of a sustainable tourism industry in Trinidad and Tobago by emphasizing the need for effective planning, and by providing a policy framework within which sustainable tourism can take place. The focus will be on how policy and planning approaches can facilitate a move towards a more sustainable form of tourism development.

description: A new baryonic state $Λ_{c}(2940)^{+}$ has recently been discovered by the Babar collaboration in the $D^{0}p$ channel. Later Belle collaboration also observed this state in the $Σ_c(2455)^{0,++} π^{\pm}\to Λ_{c}^{+}π^{+}π^{-}$ channel. The mass of $Λ_{c}(2940)^{+}$ is just a few MeV below the sum of $D^{*0}$ and $p$ masses suggesting a possibility that this state may be a $D^{*0} p$ molecular state. In this paper we study whether such a molecular state can be consistent with data. We find that the molecular structure can explain data and that if $Λ_c(2940)^+$ is a $D^{*0} p$ molecular state it is likely a $1/2^-$ state. Several other decays modes are also suggested to further test the molecular structure of $Λ_c^+(2940)$.

description: We investigate configuration-space integrals over punctured Riemann spheres from the viewpoint of the motivic Galois coaction and double-copy structures generalizing the Kawai-Lewellen-Tye (KLT) relations in string theory. For this purpose, explicit bases of twisted cycles and cocycles are worked out whose orthonormality simplifies the coaction. We present methods to efficiently perform and organize the expansions of configuration-space integrals in the inverse string tension $α'$ or the dimensional-regularization parameter $ε$ of Feynman integrals. Generating-function techniques open up a new perspective on the coaction of multiple polylogarithms in any number of variables and analytic continuations in the unintegrated punctures. We present a compact recursion for a generalized KLT kernel and discuss its origin from intersection numbers of Stasheff polytopes and its implications for correlation functions of two-dimensional conformal field theories. We find a non-trivial example of correlation functions in $(\mathfrak{p},2)$ minimal models, which can be normalized to become uniformly transcendental in the $\mathfrak{p} \to \infty$ limit.

description: The stability problem of Randall-Sundrum braneworld is readdressed in the light of stabilizing bulk scalar fields. It is shown that in such scenario the instability persists because of back-reaction even when an arbitrary potential is introduced for a canonical scalar field in the bulk. It is further shown that a bulk scalar field can indeed stabilize the braneworld when it has a tachyon-like action. The full back-reacted metric in such model is derived and a proper resolution of the hierarchy problem (for which the Randall Sundrum scenario was originally proposed) is found to exist by suitable adjustments of the parameters of the scalar potential.

description: Finding the similarities and differences between groups of datasets is a fundamental analysis task. For high-dimensional data, dimensionality reduction (DR) methods are often used to find the characteristics of each group. However, existing DR methods provide limited capability and flexibility for such comparative analysis as each method is designed only for a narrow analysis target, such as identifying factors that most differentiate groups. This paper presents an interactive DR framework where we integrate our new DR method, called ULCA (unified linear comparative analysis), with an interactive visual interface. ULCA unifies two DR schemes, discriminant analysis and contrastive learning, to support various comparative analysis tasks. To provide flexibility for comparative analysis, we develop an optimization algorithm that enables analysts to interactively refine ULCA results. Additionally, the interactive visualization interface facilitates interpretation and refinement of the ULCA results. We evaluate ULCA and the optimization algorithm to show their efficiency as well as present multiple case studies using real-world datasets to demonstrate the usefulness of this framework.

description: In this work, we propose that detecting the polarization information of $χ_{cJ}\to ϕϕ~(J=0,1,2)$ can be as good test of the role of hadronic loop effect on these decays. Our results shows that the obtained ratios of helicity amplitudes are quite stable, which are $|F_{1,1}^{(0)}/F_{0,0}^{(0)}| \approx 0.359$, $|F_{1,0}^{(1)}/F_{0,1}^{(1)}| =1$, $|F_{1,1}^{(1)}/F_{0,1}^{(1)}| =0$, $|F^{(2)}_{1,0}|/|F^{(2)}_{0,0}|=|F^{(2)}_{0,1}|/|F^{(2)}_{0,0}| \approx 1.285,~|F^{(2)}_{1,-1}|/|F^{(2)}_{0,0}|=|F^{(2)}_{-1,1}|/|F^{(2)}_{0,0}| \approx 5.110$ and $|F^{(2)}_{-1,-1}|/|F^{(2)}_{0,0}|=|F^{(2)}_{1,1}|/|F^{(2)}_{0,0}| \approx 0.465$. By adopting these predicted ratios, we further generate Monte-Carlo events of moments $\langle t_{ij} \rangle$, which are directly related to the determination of helicity amplitudes. We suggest further experiments like BESIII and Belle II to perform an analysis on the polarizations of the $χ_{cJ}\to ϕϕ$ process in the future, which is important to understand the underlying decay mechanism existing in $χ_{cJ}$ decays.

description: The ACS Virgo Cluster Survey consists of HST ACS imaging for 100 early-type galaxies in the Virgo Cluster, observed in the F475W and F850LP filters. We derive distances for 84 of these galaxies using the method of surface brightness fluctuations (SBFs), present the SBF distance catalog, and use this database to examine the three-dimensional distribution of early-type galaxies in the Virgo Cluster. The SBF distance moduli have a mean (random) measurement error of 0.07 mag (0.5 Mpc), or roughly 3 times better than previous SBF measurements for Virgo Cluster galaxies. Five galaxies lie at a distance of ~23 Mpc and are members of the W' cloud. The remaining 79 galaxies have a narrow distribution around our adopted mean distance of 16.5+/-0.1 (random mean error) +/-1.1 Mpc (systematic). The rms distance scatter of this sample is 0.6+/-0.1 Mpc, with little dependence on morphological type or luminosity class (i.e., 0.7+/-0.1 and 0.5+/-0.1 Mpc for the giants and dwarfs, respectively). The back-to-front depth of the cluster measured from our sample of galaxies is 2.4+/-0.4 Mpc (i.e., +/-2sigma of the intrinsic distance distribution). The M87 (cluster A) and M49 (cluster B) subclusters are found to lie at distances of 16.7+/-0.2 and 16.4+/-0.2 Mpc, respectively. There may be a third subcluster associated with M86. A weak correlation between velocity and line-of-sight distance may be a faint echo of the cluster velocity distribution not having yet completely virialized. In three dimensions, Virgo's early-type galaxies appear to define a slightly triaxial distribution, with axis ratios of (1:0.7:0.5). The principal axis of the best-fit ellipsoid is inclined ~20-40 deg. from the line of sight, while the galaxies belonging to the W' cloud lie on an axis inclined by ~10-15 deg.

Design and control of a bilateral motion-scaling system using magnetic levitation
Creators: name: Yan, Joseph
Publisher: name: University of British Columbia

description: Microsurgery is an ideal field to utilize the advantages of robotic technology because the tasks involve tool positioning and force sensing capabilities beyond the normal range of human abilities. A robotic manipulator that can reliably extend the surgeon’s manipulation ability by scaling down hand motions and scaling up tool forces would be extremely useful in facilitating microsurgery and alleviating the physical and psychological stress many microsurgeons face in their work. The work described involves the development of a prototype bilateral teleoperation system for experiments in microsurgery. A dual-stage approach is proposed in which two magnetically levitated wrists (a macro-master and a micro-slave) would share a common base positioned at the surgical site by a coarse-motion transport robot. The system hard ware is described in the first part of the thesis including a discussion on the proposed features and the issues in the slave wrist design. In the second part, aspects of coordi nation and control both at the coarse-positioning stage and the fine-motion scaling level are presented. More specifically, an H-based approach to controller design permitting a convenient means to find a compromise between performance and robustness is presented and then experimentally demonstrated.

description: In this work, a novel approach for the reliable and efficient numerical integration of the Kuramoto model on graphs is studied. For this purpose, the notion of order parameters is revisited for the classical Kuramoto model describing all-to-all interactions of a set of oscillators. First numerical experiments confirm that the precomputation of certain sums significantly reduces the computational cost for the evaluation of the right-hand side and hence enables the simulation of high-dimensional systems. In order to design numerical integration methods that are favourable in the context of related dynamical systems on network graphs, the concept of localised order parameters is proposed. In addition, the detection of communities for a complex graph and the transformation of the underlying adjacency matrix to block structure is an essential component for further improvement. It is demonstrated that for a submatrix comprising relatively few coefficients equal to zero, the precomputation of sums is advantageous, whereas straightforward summation is appropriate in the complementary case. Concluding theoretical considerations and numerical comparisons show that the strategy of combining effective community detection algorithms with the localisation of order parameters potentially reduces the computation time by several orders of magnitude.

description: The large-N expansion of the quasi-two-dimensional quantum nonlinear $σ$ model (QNLSM) is used in order to establish experimentally applicable universal scaling relations for the quasi-two-dimensional Heisenberg antiferromagnet. We show that, at $N=\infty$, the renormalized coordination number introduced by Yasuda \textit{et al.}, Phys. Rev. Lett. \textbf{94}, 217201 (2005), is a universal number in the limit of $J'/J\to 0$. Moreover, similar scaling relations proposed by Hastings and Mudry, Phys. Rev. Lett. \textbf{96}, 027215 (2006), are derived at $N=\infty$ for the three-dimensional static spin susceptibility at the wave vector $(π,π,0)$, as well as for the instantaneous structure factor at the same wave vector. We then use 1/N corrections to study the relation between interplane coupling, correlation length, and critical temperature, and show that the universal scaling relations lead to logarithmic corrections to previous mean-field results.

description: The aim of the present thesis was the study of the new rules that compose the Economic Governance of European Union and Eurozone, in light of constitutional law. Particularly, it was examined the initial system of Economic Governance as it was established by the Treaty of Maastricht. Furthermore, it was analyzed the conceptual and regulatory content of the term of European Economic Governance and its relation to international debate relating to the notion of governance. Then, it was presented thoroughly both the new rules, which were introduced to the system of European Economic Governance since 2010 and the constitutional implications and institutional challenges of the revised European Economic Governance. In addition, it was examined the proposals relating to the improvement of democratic standards of function of the European Economic Governance, especially the democratic legitimacy and accountability. Finally, in the last chapter, it was presented certain concluding remarks and the central issues of the discussion around the new architecture of European Economic Governance

description: Two distinct perspectives have dominated the theoretical context of our study;Education Philosophy on the one hand, and Theology of Education on the other. Weprimarily focus on the educational theory of Dietrich Benner and his positions on therole of the school as a transitory educational institution between family and societylinked . Secondly, we rely on the theological view of congregational educationreflected by St. Cyril's of Jerusalem Catechetical Lectures from which the church’scharacter on catechetical ministry mystagogy emerges.Reflections resulting from the study's evidence are supposed to shed light on whetherand how teacher training programs have an impact on School Religious Education'steaching practice. This would be an important factor, adding both to teacher trainingstandards and the effectiveness of religious education practice in Greek publicschools.

description: Single crystals of KSbO3-type rhenium oxides, La4Re6O$19, Pb6Re6O19, Sr2Re3O9 and Bi3Re3O11, were synthesized by a hydrothermal method. Their crystal structures can be regarded as a network of three-dimensional orthogonal-dimer lattice of edge-shared ReO6 octahedra. All of them exhibit small magnitude of Pauli paramagnetism, indicating metallic electronic states without strong electron correlations. The resistivity of these rhenates, except Bi3Re3O11, have a temperature dependence of $rho(T)=ρ_{0}+AT^{n}$ $(n \approx 1.6)$ in a wide temperature range between 5 K and 300 K, which is extraordinary for three-dimensional metals without strong electron correlations. The resistivity of Bi3Re3O11 shows an anomaly around at 50 K, where the magnetic susceptibility also detects a deviation from ordinary Pauli paramagnetism.

description: We investigate numerically the hydrodynamic instability of an ionization front (IF) accelerating into a molecular cloud, with imposed initial perturbations of different amplitudes. When the initial amplitude is small, the imposed perturbation is completely stabilized and does not grow. When the initial perturbation amplitude is large enough, roughly the ratio of the initial amplitude to wavelength is greater than 0.02, portions of the IF temporarily separate from the molecular cloud surface, locally decreasing the ablation pressure. This causes the appearance of a large, warm HI region and triggers nonlinear dynamics of the IF. The local difference of the ablation pressure and acceleration enhances the appearance and growth of a multimode perturbation. The stabilization usually seen at the IF in the linear regimes does not work due to the mismatch of the modes of the perturbations at the cloud surface and in density in HII region above the cloud surface. Molecular pillars are observed in the late stages of the large amplitude perturbation case. The velocity gradient in the pillars is in reasonably good agreement with that observed in the Eagle Nebula. The initial perturbation is imposed in three different ways: in density, in incident photon number flux, and in the surface shape. All cases show both stabilization for a small initial perturbation and large growth of the second harmonic by increasing amplitude of the initial perturbation above a critical value.
