Publisher: name: Karlsruhe
Year: 2008

description: Many distributed inference problems in wireless sensor networks can be represented by probabilistic graphical models, where belief propagation, an iterative message passing algorithm provides a promising solution. In order to make the algorithm efficient and accurate, messages which carry the belief information from one node to the others should be formulated in an appropriate format. This paper presents two belief propagation algorithms where non-linear and non-Gaussian beliefs are approximated by Fourier density approximations, which significantly reduces power consumptions in the belief computation and transmission. We use self-localization in wireless sensor networks as an example to illustrate the performance of this method.
Class voting in Canada, 1962-1968 : an analysis of the Canadian Institute of Public Opinion surveys.
Creators: name: Fyffe, Gregory George
Publisher: name: University of British Columbia
Year: 2011

description: Unlike many western democracies, Canada has a party system which is not polarized in terms of class. Particularly since the early 1930's many writers have attacked "brokerage politics" on the grounds that it has enabled a small elite to control political debate, and in particular has prevented the party system from presenting meaningful alternatives for the social and economic development of the country. To people such as Frank Undorhill, Gad Horowitz and Charles Taylor, "the politics of polarization" is essential to an efficient democratic political system. Another writer, Robert R. Alford in Party and Society, has concluded that the trends in Canada towards industrialization, urbanization and secularization are bound to encourage an increase in class-oriented voting behaviour. The large numbers of people working in the cities, coupled with a decline in the salience of regional, religious and ethnic issues, will increase working class consciousness to the point where a change in the substance of political debate is feasible. The thesis examines the Canadian Institute of Public Opinion (Gallup) surveys for the 1962, 1963, 1965 and 1968 elections to see if Alford’s forecast is substantiated. There are many shortcomings in both the data, and the approach used, but the analysis would suggest that the overwhelming importance of religious and linguistic factors has not significantly declined, and as far as this thesis can detect, there has been little increase in class voting. A concluding chapter suggests other research approaches to the problem under investigation, which might well have produced different conclusions. However, a brief examination of the early political history of Canada would seem to indicate that the absorption of the working classes into the existing party system was done in such a way as to permanently restrict the extent to which a working class consciousness is likely to develop. While there are signs indicating that class-oriented voting will probably increase, it is unlikely that the polarization will ever occur to the extent possible in countries which have developed, politically and econonacally, along different lines.

description: We discuss the isentropic trajectories on the QCD phase diagram in the temperature and the quark chemical potential plane using the Nambu--Jona-Lasinio model with the Polyakov loop coupling (PNJL model). We impose a constraint on the strange quark chemical potential so that the strange quark density is zero, which is the case in the ultra relativistic heavy-ion collisions. We compare our numerical results with the truncated estimates by the Taylor expansion in terms of the chemical potential to quantify the reliability of the expansion used in the lattice QCD simulation. We finally discuss the strange quark chemical potential induced by the strangeness neutrality condition and relate it to the ratio of the Polyakov loop and the anti-Polyakov loop.

Sensor Node Localization Methods based on Local Observations of Distributed Natural Phenomena
Creators: name: Sawo, Felix

name: Sikorski, Christopher
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2008

description: This paper addresses the model-based localization of sensor networks based on local observations of a distributed phenomenon. For the localization process, we propose the rigorous exploitation of strong mathematical models of distributed phenomena. By unobtrusively exploiting background phenomena, the individual sensor nodes can be localized by only observing its local surrounding without the necessity of heavy infrastructure. In this paper, we introduce two novel approaches: (a) the polynomial system localization method (PSL-method) and (b) the simultaneous reconstruction and localization method (SRL-method). The first approach (PSLmethod) is based on restating the mathematical model of the distributed phenomenon in terms of a polynomial system. These equations depend on both the state of the phenomenon and the node locations. Solving the system of polynomials for each individual sensor node directly leads to the desired locations. The second approach (SRL-method) basically regards the localization problem as a simultaneous state and parameter estimation problem with the node locations as parameters. By this means, the distributed phenomenon is reconstructed and the individual nodes are localized in a simultaneous fashion. In addition, within this framework the uncertainties in the mathematical model and the measurements are considered. The performance of the two different localization approaches is demonstrated by means of simulation results.
The changing ISM of massive elliptical galaxies and cosmic evolution of radio galaxies and quasars

description: The recently discovered apparent dramatic expansion in the effective radii of massive elliptical galaxies from $z \simeq 2$ to $z \simeq 0.1$ has been interpreted in terms of either galaxy mergers or the rapid loss of cold gas due to AGN feedback. In examining the latter case we have quantified the extent of the expansion, which is uncertain observationally, in terms of the star formation parameters and time of the expulsion of the cold gas. In either case, the large global decrease in stellar density should translate into a major drop in the ISM density and pressure, and a much steeper radial decline in those quantities with cosmic epoch. These cosmological changes are expected to have a major influence on the gas accretion mode, which will shift from `cold' thin disk accretion at high redshifts toward `hot' Bondi fed ADAF accretion at low redshifts. The decline of angular momentum inflow would then lead to a spin down of the black hole, for which we have calculated more precise time scales; a value of about 0.2 Gyr is typical for a $10^9 M_\odot$ central black hole. These results have implications for the different cosmological evolutionary patterns found for the luminosity functions of powerful and weak radio galaxies.

description: Detailed measurements of the global and local electromagnetic properties of Ba(Fe$_{0.93}$Co$_{0.07}$)$_{2}$As$_{2}$ single crystals are reported. Analysis of the irreversible magnetic response provides strong evidence for similar vortex physics in this Fe-based pnictide superconductor to the high-$T_{c}$ cuprates, such as Y-Ba-Cu-O or Nd-Ce-Cu-O. In particular, we have found a nonmonotonic "fishtail" magnetization in $M(H,T=const)$ loops and its signature is also present in $M(H=const,T)$ scans. The supercurrent density is evaluated by using several techniques, including direct transport measurements. At 5 K we estimate its value to be a moderate $j \approx 2.6 \pm 0.2 \times 10^5$ A/cm$^2$. Analysis of the magnetic relaxation is consistent with the collective pinning and creep models (weak pinning and fast creep) and suggests a crossover from the collective to the plastic creep regime in fields exceeding the value corresponding to the maximum in fishtail magnetization.
Temperate forest soils of Tasmania and northern South Island, New Zealand : properties, distribution, genesis and implications for sustainable use : a collection of published papers and a review
Creators: name: Laffan, MD
Publisher: name: University Of Tasmania
Year: 2023

description: The thesis is a review of twenty publications including refereed papers, soil survey reports and bulletins, soil maps and books. Also included are two major unpublished reports. The primary objective of the research has been the provision of information relevant to the sustainable use of temperate forest soils. A secondary aim was to investigate soil-forming processes. To achieve these objectives, the research has included four main aspects: (1) Soil surveys to determine the properties and distribution of soils. (2) Assessment of potential soil degradation hazards resulting from forest practices. (3) Evaluation of the productive capacity of the soils and their suitability for plantation forestry. ( 4) Studies of some aspects of the genesis of temperate forest soils. Research of temperate forest soils commenced with a soil survey of the Charleston-Punakaiki region on the west coast of northern South Island, New Zealand in the mid-l 970's. A report including ratings of soil limitations affecting the growth of softwood plantations and a soil map at 1: 50 000 scale covering 36 500ha were completed. Subsequent studies concentrated on the assessment of landslide hazard and the effects of windthrow and selective logging on soil depth. Between 1978-1982 a soil survey was carried out in the Malborough Sounds region in northern South Island, New Zealand to assess soil limitations affecting plantation growth and the potential impacts on site disturbance and sediment generation from various forest practices. A soil report and map at a scale of 1: 100 000 covering about 50 000 ha were completed as part of the project. Transect studies of regolith characteristics and soil processes were also carried out. Mapping was initiated in Tasmania in 1990 to provide soil information suitable for use by forest managers for compliance with the Forest Practices Code. Soil reports and maps at 1 :50 000 were completed for 154 000ha in the north of the State together with a handbook outlining the properties and management requirements of 35 important forest soils from around Tasmania. Methodologies were also developed for assessing soil erodibility, site productivity and site suitability for plantations. Specific research was carried out to investigate impacts on soils from cable-logging steep slopes, and soil texture-profiles in relation to bioturbation by earthworms. The studies in northern South Island, New Zealand and Tasmania reviewed by the author have added substantially to information on temperate forest soils, particularly in relation to their properties, distribution and management practices required for sustainable use.
Proof of the determinantal form of the spontaneous magnetization of the superintegrable chiral Potts model

Publisher: name: arXiv
Year: 2010
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The superintegrable chiral Potts model has many resemblances to the Ising model, so it is natural to look for algebraic properties similar to those found for the Ising model by Onsager, Kaufman and Yang. The spontaneous magnetization M_r can be written in terms of a sum over the elements of a matrix S_r. The author conjectured the form of the elements, and this conjecture has been verified by Iorgov et al. The author also conjectured in 2008 that this sum could be expressed as a determinant, and has recently evaluated the determinant to obtain the known result for M_r. Here we prove that the sum and the determinant are indeed identical expressions.

description: Integrable equations with second order Lax pair like KdV and Camassa-Holm (CH) exhibit interesting conformal properties and can be written in terms of the so-called conformal invariants (Schwarz form). These properties for the CH hierarchy are discussed in this contribution. The squared eigenfunctions of the spectral problem, associated to the Camassa-Holm equation represent a complete basis of functions, which helps to describe the Inverse Scattering Transform (IST) for the Camassa-Holm hierarchy as a Generalised Fourier Transform (GFT). Using GFT we describe explicitly some members of the CH hierarchy, including integrable deformations for the CH equation. Also we show that solutions of some 2+1-dimensional generalizations of CH can be constructed via the IST for the CH hierarchy.

Publisher: name: University of British Columbia
Year: 2011

description: The strong binding of bishydroxycoumarin to serum albumin was first reported about 20 years ago. However, the mechanism of binding has not been studied. In this investigation, attempts have been made to reveal the mechanism. The work was extended to some other synthetic macromolecules including polyvinylpyrrolidone. The literature survey covers the physicochemical properties and the complexing behaviours in aqueous solution of the individual substances examined. The theory of multiple equilibria, which is fundamental to an understanding of the binding process, has been summarized. Spectrophotometric, solubility, dynamic and equilibrium dialyses, and viscometric methods were used and their theoretical back-ground has been reviewed and discussed. Some physicochemical properties of BHC, necessary for the interpretation of binding data, were estimated. Maximum binding capacities of macromolecules and association constant of each binding site were obtained from the binding data. The nature of the site and intermolecular forces were characterized from thermodynamic analysis. This abstract represents the true contents of the thesis submitted.

description: We discuss the dissipative diffusion-type term of the form $\mathbf{m}\times\nabla^2\partial_t\mathbf{m}$ in the phenomenological Landau-Lifshitz equation of ferromagnetic precession, which describes enhanced Gilbert damping of finite-momentum spin waves. This term arises physically from itinerant-electron spin flows through a perturbed ferromagnetic configuration and can be understood to originate in the ferromagnetic spin pumping in the continuum limit. We develop a general phenomenology as well as provide microscopic theory for the Stoner and s-d models of ferromagnetism, taking into account disorder and electron-electron scattering. The latter is manifested in our problem through the Coulomb drag between the spin bands. The spin diffusion is identified in terms of the transverse spin conductivity, in analogy with the Einstein relation in the kinetic theory.

The efficacy of wilderness programs with \at risk\" adolescents"
Creators: name: Lan, Paul Garon
Publisher: name: University Of Tasmania
Year: 2023

description: This document reviews literature regarding the effectiveness of adolescent wilderness programs as an intervention strategy with at-risk adolescents. It begins by exploring definitions of adolescence, the concept of adolescent risk, and briefly overviews Sveen's (1995) theoretical eclectic model of adolescent wilderness intervention (adapted from Walter and Marks' 1981 eclectic model of human functioning). An appraisal of the efficacy of wilderness programs with adolescents then follows. The accumulated evidence indicates positive effects of wilderness programs in areas such as self-concept, self-esteem, social skills, self-responsibility, and self-control. However, this evidence is presented with the caveat of the intrinsic difficulties particular to evaluating these types of programs, and individual studies and meta-analytic studies are used to illustrate substantive and methodological issues in the evaluation of wilderness programs. Suggestions for future research are presented with the aim of minimising the difficulties of previous research.

BPS states in (2,0) theory on R x T5
Creators: name: Henningson, Mans
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider $(2, 0)$ theory on a space-time of the form $R \times T^5$, where the first factor denotes time, and the second factor is a flat spatial five-torus. In addition to their energy, quantum states are characterized by their spatial momentum, 't Hooft flux, and $Sp (4)$ $R$-symmetry representation. The momentum obeys a shifted quantization law determined by the 't Hooft flux. By supersymmetry, the energy is bounded from below by the magnitude of the momentum. This bound is saturated by BPS states, that are annihilated by half of the supercharges. The spectrum of such states is invariant under smooth deformations of the theory, and can thus be studied by exploiting the interpretation of $(2, 0)$ theory as an ultra-violet completion of maximally supersymmetric Yang-Mills theory on $R \times T^4$. Our main example is the $A$-series of $(2,0)$ theories, where such methods allow us to study the spectrum of BPS states for many values of the momentum and the 't Hooft flux. In particular, we can describe the $R$-symmetry transformation properties of these states by determining the image of their $Sp (4)$ representation in a certain quotient of the $Sp (4)$ representation ring.

Comparative ecophysiology, chemotaxonomy and ichthyotoxicity of Chattonella marina (Raphidophyceae) from Australia and Japan
Creators: name: Marshall, JA
Publisher: name: University Of Tasmania
Year: 2023

description: The raphidophyte flagellate Chattonella Marina from South Australia that was associated with the mortality of farmed tuna in April 1996 was successfully cultured. This study investigates ecophenotypic variation in physiology, chemotaxonomy and ichthyotoxicity of Australian and Japanese C. marina. Australian C. marina had similar temperature and salinity requirements to the Japanese strain but was adapted to higher light intensities than the Japanese strain. This differentiation was reflected in high concentrations of mycosporinelike amino acids (MAA's), especially the antioxidant MAA mycosporine-glycine, in the Australian cultures. Mycosporine-glycine was absent in the Japanese strain which instead used a violaxanthin:zeaxanthin cycle to moderate inhibition by high PAR irradiance. Ecophenotypic variations in lipid profiles were also observed between Chattonella strains from different geographic locations. Fatty acid and sterol profiles allowed for a clear discrimination between the raphidophyte genera Chattonella, Heterosigma, Fibrocapsa and Olisthodiscus, but exhibited little differentiation between C. marina, C. antiqua and C. subsalsa. Sterol and fatty acid profiles do not support the separation of C. antiqua and C. marina as distinct species. Sterol signatures, which may be useful as chemotaxonomic markers, were identified. Lipid composition correlated more closely to recent molecular classification of raphidophytes than classification based upon carotenoid pigments. Previous research on ichthyotoxic principles of C. marina has focused on production of high levels of reactive oxygen species (ROS), a brevetoxin-like compound and free fatty acids. This study found that Chattonella marina produces levels of the ROS superoxide 100 times higher than most algae, which is partially controlled by electrons donated through photosynthetic electron transfer. Differing superoxide production and toxic effects on zooplankton and fish are documented between different geographic strains of C. marina and light treatments. These results suggest a synergistic effect between ROS and an ichthyotoxin, and cannot be explained on the basis of these mechanisms of toxicity on their own. Our investigations into Australian C. marina demonstrate an absence or only very low concentrations of brevetoxin-like compounds by LC-MS techniques and negative mouse bioassays. All raphidophyte species were found to have high levels of eicosapentaenoic acid (EPA), which tested positive as a potential ichthyotoxin using damselfish as a model organism. EPA produced a similar mortality and fish behavioural response to that of intact C. marina cells while superoxide alone was not sufficient to cause fish mortality. However, superoxide in combination with low concentrations of EPA accelerated fish mortality. Implications of this work for mitigating the impact of Chattonella algal blooms on finfish aquaculture are discussed.

Publisher: name: Karlsruhe
Year: 2008

description: In seismic, radar, and sonar imaging the exact determination of the reflectivity distribution is usually intractable so that approximations have to be applied. A method called synthetic aperture focusing technique (SAFT) is typically used for such applications as it provides a fast and simple method to reconstruct (3D) images. Nevertheless, this approach has several drawbacks such as causing image artifacts as well as offering no possibility to model system-specific uncertainties. In this paper, a statistical approach is derived, which models the region of interest as a probability density function (PDF) representing spatial reflectivity occurrences. To process the nonlinear measurements, the exact PDF is approximated by well-placed Extended Kalman Filters allowing for efficient and robust data processing. The performance of the proposed method is demonstrated for a 3D ultrasound computer tomograph and comparisons are carried out with the SAFT image reconstruction.

description: Observations and numerical magnetohydrodynamic (MHD) simulations indicate the existence of outflows and ordered large-scale magnetic fields in the inner region of hot accretion flows. In this paper we present the self-similar solutions for advection-dominated accretion flows (ADAFs) with outflows and ordered magnetic fields. Stimulated by numerical simulations, we assume that the magnetic field has a strong toroidal component and a vertical component in addition to a stochastic component. We obtain the self-similar solutions to the equations describing the magnetized ADAFs, taking into account the dynamical effects of the outflow. We compare the results with the canonical ADAFs and find that the dynamical properties of ADAFs such as radial velocity, angular velocity and temperature can be significantly changed in the presence of ordered magnetic fields and outflows. The stronger the magnetic field is, the lower the temperature of the accretion flow will be, and the faster the flow rotates. The relevance to observations is briefly discussed.

Year: 2023

description: ...The focus of this research was to measure the students' level of satisfaction with Asynchronous E-learning Systems. A quantitative method was implemented in this research. A web-based questionnaire was sent out to 1079 students currently studying in three universities within Australia. This research found that the students were satisfied with the Asynchronous E-learning Systems. A number of factors were analysed in relation with student satisfaction. Content reported being the factor that correlated highest with the students' level of satisfaction while Access reported being the lowest factor that correlated highest with the students' level of satisfaction. This research also reported that electronic mails, course online notes and website links are the most used Asynchronous E-learning tools, based on students familiarity with the tools. Also, this research managed to highlight other issues with regards to E-learning Systems, such as the investment considerations in E-learning as well as the need for prior training in the systems for the users. Overall, this research managed to extend the knowledge in the area of university students' satisfaction, specifically with Asynchronous E-learning Systems.

description: For q a root of unity of order 2r, we give explicit formulas of a family of 3-variable Laurent polynomials J_{i,j,k} with coefficients in Z[q] that encode the 6j-symbols associated with nilpotent representations of U_qsl_2. For a given abelian group G, we use them to produce a state sum invariant tau^r(M,L,h_1,h_2) of a quadruplet (compact 3-manifold M, link L inside M, homology class h_1\in H_1(M,Z), homology class h_2\in H_2(M,G)) with values in a ring R related to G. The formulas are established by a "skein" calculus as an application of the theory of modified dimensions introduced in [arXiv:0711.4229]. For an oriented 3-manifold M, the invariants are related to TV(M,L,f\in H^1(M,C^*)) defined in [arXiv:0910.1624] from the category of nilpotent representations of U_qsl_2. They refine them as TV(M,L,f)= Sum_h tau^r(M,L,h,f') where f' correspond to f with the isomorphism H_2(M,C^*) ~ H^1(M,C^*).

description: We formally link the concept of steering (a concept created by Schrodinger but only recently formalised by Wiseman, Jones and Doherty [Phys. Rev. Lett. 98, 140402 (2007)] and the criteria for demonstrations of Einstein-Podolsky-Rosen (EPR) paradox introduced by Reid [Phys. Rev. A, 40, 913 (1989)]. We develop a general theory of experimental EPR-steering criteria, derive a number of criteria applicable to discrete as well as continuous-variables observables, and study their efficacy in detecting that form of nonlocality in some classes of quantum states. We show that previous versions of EPR-type criteria can be rederived within this formalism, thus unifying these efforts from a modern quantum-information perspective and clarifying their conceptual and formal origin. The theory follows in close analogy with criteria for other forms of quantum nonlocality (Bell-nonlocality, entanglement), and because it is a hybrid of those two, it may lead to insights into the relationship between the different forms of nonlocality and the criteria that are able to detect them.

description: Στα πλαίσια της παρούσας διπλωματικής εργασίας προσεγγίζεται, ως ένα πεδίο
διαφοροποίησης, ο τόπος του Βώλακα στην Τήνο. Ένα τοπίο αντίθεσης, ως προς την κλίμακα και την έκταση των γρανιτικών σχηματισμών του- του γεωλογικού φαινομένου του.
Το γεωλογικό εσωτερικό με έντονα σημάδια αποσάθρωσης, μεταβολές στον χώρο και στον χρόνο, ιδωμένο με εξογκώματα και οπές. Ένα μέρος όπου το αρχιτεκτονικό αποτύπωμα είναι δυσδιάκριτο καθώς το τοπίο υπερισχύει.
Η ένταση των εξάρσεων του εδάφους εδώ είναι κυρίαρχη και ως ένας τέτοιος τόπος επιλέγεται. Ως δυναμική αποσταθεροποίησης δυνατής να εισάγει και να παράγει χωρικές συνέργειες. Πειραματισμοί σε σχέση με το «πραγματικό» και την «κατασκευή».

Έχοντας ως έναυσμα τον Βώλακα, πρόθεση αποτελεί να χαρτογραφηθούν ρυθμοί και ποιότητες του χώρου που συνιστούν στην αποσταθεροποίηση ή στοιχεία που εντοπίζονται εκτός ισορροπίας· μη αναμενόμενα στοιχεία που τον συνθέτουν σε μια προσπάθεια αντιστροφής της παραγωγής του χώρου.
Στόχο λοιπόν αποτελεί η εννοιολογική διάσχιση του τοπίου και η συσχέτιση με
«πρωταρχικούς» τόπους (1) ως πεδία ανάλυσης, μέσω «λοξών» διαδρομών. Έτσι ώστε να αρθρωθεί ένα μέσο εξερεύνησης, με έμφαση στη διαδικασία ως εργαλείο της χωρικής διερεύνησης-σχεδίασης. Με την αντιστροφή των ποιοτήτων που αντλήθηκαν από τη συγκεκριμένη θεματική, τις υλικές και φαντασιακές προεκτάσεις του χώρου, στη σύνθεση ενός δυνητικού «εδάφους», ενός προσωρινού χώρου.

description: In the context of this dissertation, the place of Volakas in Tinos is approached as a field of differentiation.  A landscape of contrast, in terms of the scale and extent of its granitic formations - its geological phenomenon. The geological interior with strong signs of disintegration and changes in space and time is seen with bumps and holes.
A place where the architectural footprint is indistinguishable as the landscape prevails.
The intensity of the soil eruptions here is predominant and is chosen as such a place. As a destabilizing dynamic capable of introducing and producing spatial synergies. Experiments with "real" and "construction".
Initiated by Volakas, the intention is to map the rhythms and qualities of space that constitute destabilization or elements that are found out of balance; unexpected elements that compose the place in an attempt to reverse the "production" of space.
The goal is therefore the conceptual crossing of the landscape and the correlation with "primary" places as fields of analysis, throughout "oblique" routes. To articulate means of exploration, with an emphasis on process as a tool of spatial research design. By reversing the qualities drawn from this specific theme, the material and imaginary extensions of the space, to the composition of a dynamic "ground", a temporary space.
The synthesis and decomposition behaviour of methylpalladium (II) N-heterocyclic carbene complexes
Creators: name: Magill, Alison Mary
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis describes the synthesis of methylpalladium(II) complexes bearing various N-heterocyclic carbene (NHC) ligands. The decomposition behaviour of a subset of these complexes is also studied. The catalytic performance of methylpalladium(II) complexes bearing NHC ligands of similar steric bulk but varying basicities was assessed. Palladium(II) complexes bearing two large NHCs were found to be inactive in the Heck reaction of 4-bromoacetophenone and n-butyl acrylate, while methylpalladium(II) carbene dimers bearing bridging halide groups were found to be active pre-catalysts. Ligand basicity was shown, in some cases, to dramatically influence catalytic activity. In addition, the catalytic activity of [Pd(NHC)Me(PP)J13F4-type complexes was assessed. Such complexes were also found to be inactive.

description: There has been tremendous research activity in the field of magneto-electric (ME) multiferroics after Kimura et al. [1] showed that antiferromagnetic and ferroelectric order coexist in orthorhom- bically distorted perovskite TbMnO3 and are strongly coupled. It is now generally accepted that ferroelectricity in TbMnO3 is induced by magnetic long range order that breaks the symmetry of the crystal and creates a polar axis [2]. One remaining key question is whether magnetic order can induce ferroelectric polarization that is as large as that of technologically useful materials. We show that ferroelectricity in orthorhombic (o) TmMnO3 is induced by collinear magnetic order, and that the lower limit for its electric polarization is larger than in previously investigated orthorhombic heavy rare-earth manganites. The temperature dependence of the lattice constants provides fur- ther evidence of large spin-lattice coupling effects. Our experiments suggest that the ferroelectric polarization in the orthorhombic perovskites with commensurate magnetic ground states could pass the 1 microC/cm2 threshold, as suggested by theory [3, 4].

description: Scandium, a rare earth element, is primarily used in aluminum alloying and other specialty applications.
This metal is one of the elements listed on the USGS 2022 List of Critical Minerals. The Russia-Ukraine war
has the potential to disrupt supplies of this metal. Beyond Russia and Ukraine, only a few other nations
are producers of scandium such as China and Kazakhstan. This executive briefing provides information on
scandium’s uses, sources, market, and trade data to help put this situation into context.
Graphical description of local Gaussian operations for continuous-variable weighted graph states
Creators: name: Zhang, Jing
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The form of a local Clifford (LC, also called local Gaussian (LG)) operation for the continuous-variable (CV) weighted graph states is presented in this paper, which is the counterpart of the LC operation of local complementation for qubit graph states. The novel property of the CV weighted graph states is shown, which can be expressed by the stabilizer formalism. It is distinctively different from the qubit weighted graph states, which can not be expressed by the stabilizer formalism. The corresponding graph rule, stated in purely graph theoretical terms, is described, which completely characterizes the evolution of CV weighted graph states under this LC operation. This LC operation may be applied repeatedly on a CV weighted graph state, which can generate the infinite LC equivalent graph states of this graph state. This work is an important step to characterize the LC equivalence class of CV weighted graph states.

description: Исследуется дифракция плоской звуковой волны на упругом цилиндре с непрерывно-слоистым покрытием, находящимся вблизи абсолютно твердой или акустически мягкой подстилающей поверхности. Рассчитаны полярные диаграммы направленности рассеянного акустического поля и показано влияние на них неоднородности покрытия и акустических свойств поверхности. В классе квадратичных функций найдены плотность и модули упругости покрытия, обеспечивающие минимальную интенсивность рассеяния звука в заданном секторе углов наблюдения в случае, когда цилиндр с покрытием находится вблизи акустически мягкой поверхности.
An examination of urban area S.T.O.L. airports
Creators: name: Morris, David William
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is an examination of the problems that may arise from the location of S.T.O.L. airports within urbanized areas. The role of air transportation as a passenger travel mode is considered and the problems facing the existing air transportation system are explored. The potential role of S.T.O.L. aircraft within the air transportation system is examined in detail. Additionally, the benefits that may accrue from the use of S.T.O.L. aircraft in a regional air transport system are discussed extensively. The criteria to be used when looking for potential S.T.O.L. airport sites are examined in detail. These criteria are applied to three potential S.T.O.L. airport sites within the Vancouver urban area. In some cases the locational criteria were found to be difficult to operationalize. Data on community reaction to noise exposure is inadequate and noise standards are difficult to apply on a wide basis. The concept of land use compatibility around airports is useful but only to the extent that it does not obscure the fact that aircraft operations can cause community disruptions beyond the boundaries of the so-called compatible land uses. With specific reference to Vancouver, the available data indicates, that on the average, very little terminal access or egress time will be saved if a S.T.O.L. airport were built at a suitable location between the existing airport and the downtown area. Finally, the paper concludes by suggesting that despite the fact that S.T.O.L. aircraft cannot bring substantial time savings to regional air passengers, a S.T.O.L. air service may mean that many of the regions under utilized conventional airports could be converted to S.T.O.L. airports and yeild substantial savings in the money used to maintain and operate the publically owned airports in the province.
