Undergraduate student acceptance of haptic simulation in gross anatomy learning
Creators: name: Yeom, Soonja
Publisher: name: University Of Tasmania

description: Factors influencing undergraduate students' acceptance of a computer-aided learning (CAL) resource for learning anatomy were researched and evaluated. The resource used the Phantom Omni haptic stylus, which enables the user to rotate, receive touch and kinaesthetic feedback, and display the names of three-dimensional (3D) human anatomical structures. The perceived value of the system was investigated with respect to user characteristics and system functionality. The Learning Anatomy with Haptic Feedback System (LAHFS) was developed using the software development life cycle over three stages. It was tested by students enrolled in bachelor degrees, including medicine, health sciences, education, and computing. Their responses and attitudes towards LAHFS were investigated using action research and design research methodology frameworks, and quantitative and qualitative data were analysed using mixed methods. Participants generally thought the haptic learning system was useful, was easy to use, and that they had performed well with it. Their perception of any negative aspects was low, with little experience of mental or physical stress. User intention to use the system or recommend it to others correlated with their perception of usefulness and ease of use, more strongly with the former. Ease of use ratings were significantly correlated with perceptions of system usefulness and the usefulness of a quiz introduced in the final version. Students with greater kinaesthetic learning preferences tended to rate the system higher, and students with prior experience with 3D interfaces had higher intention to use the system. Previous experience with haptic interfaces did not affect user acceptance. Despite rating their performance with the system lower, females were more likely to use or recommend the system than males. Qualitative analysis of feedback on the LAHFS system indicated that haptic feedback and 3D visualisation were considered the best aspects of the system. Suggested improvements included more rapid response times and extension to a three dimensional display. Rankings of various learning resources suggested LAHFS may be a better way of learning anatomy than websites, other software, or anatomical atlases. Ease of use ratings declined across the three versions as modules were added and system complexity increased. Much previous research relating to haptic devices in medical and health sciences has focused on advanced trainees learning surgical or procedural skills. This study suggests that incorporating haptic feedback into virtual anatomical models is a useful strategy at an undergraduate level.

Mountain ecosystem
Climate change

description: European mountain landscape faces unique global change challenges but also offers opportunities for sustainable development. The specific role of mountain ecosystems in climate change regulation arises from their capacity to capture significant amount of carbon in vegetation and soil organic matter in the long term. In spite of the importance of European mountain ecosystems to provide carbon sequestration ecosystem service has been overlooked long time, the need to reverse their degradation has already been noted within the broader debate about climate change, especially since Rio Earth Summit in 1992. Nowadays, mountain sustainable development is top policy agenda. In this paper, we investigate the potential of carbon forestry as an innovative technological-governance approach for effective forest management addressing responses to global change climate impacts. Furthermore, we analyse the adaptive mechanism of different resource regimes (state, private, commons) contributing to global change vulnerabilities and promoting social innovations in forest resource governance as well as well-being of European mountain regions. The research demonstrates comparative analyses of eight forest regimes in European continental mountains and Northern Europe applying expert assessment to determine factors influencing the vulnerability and resilience of forest regimes and estimate the intensity of used carbon forest management practices. Moreover, carbon sequestration potential of selected forest regimes is calculated.
Higgs boson pair production through gauge boson fusion at linear colliders within the general 2HDM

description: Inclusive Higgs boson pair production through the mechanism of gauge boson fusion e^{+} e^{-} -> V* V* -> h h + X (V=W,Z) in the general Two-Higgs-Doublet Model (2HDM), with h=h^0,H^0,A^0,H^{\pm}, is analyzed at order α^4_{ew} in the linear colliders ILC and CLIC. This kind of processes is highly sensitive to the trilinear Higgs (3H) boson self-interactions and hence can be a true keystone in the reconstruction of the Higgs potential. For example, in the ILC at 1 TeV, the most favorable scenarios yield cross-sections up to roughly 1 pb, thus entailing 10^5 events per 100 fb^{-1} of integrated luminosity, whilst remaining fully consistent with the perturbativity and unitarity bounds on the 3H couplings, the electroweak precision data and the constraints from BR(b->sγ). Comparing with other competing mechanisms, we conclude that the Higgs boson-pair events could be the dominant signature for Higgs-boson production in the TeV-class linear colliders for a wide region of the 2HDM parameter space, with no counterpart in the Minimal Supersymmetric Standard Model. Owing to the extremely clean environment of these colliders, inclusive 2H events should allow a comfortable tagging and might therefore open privileged new vistas into the structure of the Higgs potential.

Cell suspension culture studies of the Coffea arabica L.
Creators: name: Buckland, Elizabeth J.
Publisher: name: University of British Columbia
Year: 2011

description: Cultured tissues derived from the coffee plant, Coffea arabica L., were grown in vitro in the form of both callus and suspension cultures. The suspension cultures grew rapidly and appeared healthy. Microscopic examination showed that the cells characteristically grew in long filamentous chains. Suspension cultures were examined for the presence of three components - free amino acids, caffeine and chlorogenic acid. By examining these components the species specificity could be determined. The free amino acids of the coffee bean are thought to be one of the major precursors of coffee aroma on roasting. The coffee suspension cultures were shown to contain a similar pattern of free amino acids although the total content was much higher in the cultures than in the intact green coffee bean. Aspartic acid, glutamic acid, phenylalanine, alanine, valine, threonine, serine, and glycine were the predominant amino acids present in the coffee suspension culture. Threonine, serine, glycine, alanine and phenylalanine were the major free amino acids in the green coffee bean. The free amino acid content in the suspension culture exhibited an initial rise, decreased during active growth, then increased rapidly to the maximum level during the decline of the culture. Roasted coffee bean extracts were investigated to ascertain whether one solvent could in preference extract some of the major precursors of coffee aroma. Methanol was found to extract material from green coffee beans which on roasting produced coffee aroma. Caffeine was detected in the cell suspension cultures. However, problems with the analytical methods gave rise to questionable results. The suspension cultures, at maximum caffeine yield, contained 0.03% caffeine (dry weight) whereas the green coffee bean contained considerably more caffeine (1.15%, dry weight). The caffeine content of the tissues increased during the lag phase, decreased during the rapid phase and then increased again in the stationary phase and ultimately production levelled off during the deline phase of growth. The cell cultures produced chlorogenic acid in low concentrations at the maximum 0.14% dry weight in contrast to the green coffee bean which contains 6.5% dry weight. The production or accumulation of chlorogenic acid followed a similar pattern to that of the cell caffeine production over the growth curve. Caffeic acid was also detected. The cell suspension cultures of Coffea arabica L. were shown to be species specific in their biochemical capabilities.

description: Under the framework of the semiclassical theory, we investigate the equilibrium-state properties of a spin polarized dipolar Fermi gas through full numerical calculation. We show that the Fermi surfaces in both real and momentum spaces are stretched along the attractive direction of dipolar interaction. We further verify that the deformed Fermi surfaces can be well approximated by ellipsoids. In addition, the deformation parameters slightly depend on the local real- and momentum-space densities. We also study the interaction strength dependence of the energy and real- and momentum-space densities. By comparing them with variational results, we find that the ellipsoidal ansatz usually generates accurate results for weak dipolar interaction, while under strong dipolar interaction limit, notable discrepancy can be observed. Finally, we map out the stability boundary of the system.

description: Context: IRAS 04166+2706 in Taurus is one of the most nearby young stellar objects whose molecular outflow contains a highly collimated fast component. Methods: We have observed the IRAS 04166+2706 outflow with the IRAM Plateau de Bure interferometer in CO(J=2-1) and SiO(J=2-1) achieving angular resolutions between 2'' and 4''. To improve the quality of the CO(2-1) images, we have added single dish data to the interferometer visibilities. Results: The outflow consists of two distinct components. At velocities <10 km/s, the gas forms two opposed, approximately conical shells that have the YSO at their vertex. These shells coincide with the walls of evacuated cavities and seem to result from the acceleration of the ambient gas by a wide-angle wind. At velocities >30 km/s, the gas forms two opposed jets that travel along the center of the cavities and whose emission is dominated by a symmetric collection of at least 7 pairs of peaks. The velocity field of this component presents a sawtooth pattern with the gas in the tail of each peak moving faster than the gas in the head. This pattern, together with a systematic widening of the peaks with distance to the central source, is consistent with the emission arising from internal working surfaces traveling along the jet and resulting from variations in the velocity field of ejection. We interpret this component as the true protostellar wind, and we find its composition consistent with a chemical model of such type of wind. Conclusions: Our results support outflow wind models that have simultaneously wide-angle and narrow components, and suggest that the EHV peaks seen in a number of outflows consist of internally-shocked wind material.

description: In several fields like aeronautics, die and automotive, the machining of the parts is done more and more on high speed machines tools. Today, the offer for purchasing these machine tools is very wide. This situation poses the problem of the judicious and objective choice meeting industrial needs that must be necessary well expressed. The choice remains difficult insofar as the technical data provided to the customers by the manufacturers of machine tools are insufficient as well quantitatively as qualitatively. In this paper we present a protocol for the characterization of machines tools in order to direct the choice. The protocol is based on the one hand on no-load complementary tests to those recommended by the standards ISO 230 and ISO 10791 and on the other hand on the tests in load on a part test. In the first part, we present the industrial needs as well as an analysis of the technical data of machine tools. The second part is devoted to the study of the standards, the description of the protocol and the presentation of the results.

description: The features of controlling the parameters of the laser metal deposition process (LMD) by the optical signal are considered. It is shown that to control and manage the process, it is necessary to use the principles of adaptive regulation. A review of research in the field of process control systems for laser metal additive manufacturing has been carried out. The developed system for the on-line control of LMD with feedback on the optical signal from the processing zone is described. The system provides the recognition of deviations during the process in real time and performs corrective actions to maintain the processes in the required regime. The use of the developed control system led to a decrease in the deviation of the track height from the set value on the trajectories with sharp turns.

description: We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: About 20 modes of oscillation may be clearly distinguished in each star. We discuss the appearance of the oscillation spectra, use the frequencies and frequency separations to provide first results on the radii, masses and ages of the stars, and comment in the light of these results on prospects for inference on other solar-type stars that Kepler will observe.

description: We have explicitly shown that QCD is the color gauge invariant theory at non-zero mass gap as well. It has been defined as the value of the regularized full gluon self-energy at some finite point. The mass gap is mainly generated by the nonlinear interaction of massless gluon modes. All this allows one to establish the structure of the full gluon propagator in the explicit presence of the mass gap. In this case, the two independent general types of formal solutions for the full gluon propagator as a function of the regularized mass gap have been found. The nonlinear iteration solution at which the gluons remain massless is explicitly present. The existence of the solution with an effective gluon mass is also demonstrated.

description: We present the first results of the application of supervised classification methods to the Kepler Q1 long-cadence light curves of a subsample of 2288 stars measured in the asteroseismology program of the mission. The methods, originally developed in the framework of the CoRoT and Gaia space missions, are capable of identifying the most common types of stellar variability in a reliable way. Many new variables have been discovered, among which a large fraction are eclipsing/ellipsoidal binaries unknown prior to launch. A comparison is made between our classification from the Kepler data and the pre-launch class based on data from the ground, showing that the latter needs significant improvement. The noise properties of the Kepler data are compared to those of the exoplanet program of the CoRoT satellite. We find that Kepler improves on CoRoT by a factor 2 to 2.3 in point-to-point scatter.

Carborane-induced deformation of polycyclic aromatic hydrocarbons, and their intriguing emissive properties
Creators: name: Marsh, Adam Patrick Vincent
Publisher: name: Imperial College London
Year: 2019

description: Carboranes, C2B10H12, are bulky, icosahedral cluster compounds, with unique molecular bonding and electronic properties. Since their discovery in the middle of the 19th century, they have been studied and used in a wide range of chemical fields, with the aims of exploiting their excellent thermal and chemical stability, electron-withdrawing capability, and, more recently, their ability to act as modifiers and promotors of photoluminescence (PL). The effects of carboranes on PL have now been widely reported in the literature, but questions remain about the underlying processes dictating these behaviours. This work is an attempt to answer some of those questions. In this thesis, the three structural isomers of carborane (ortho, meta and para) have been incorporated into a range of linear and non-linear aromatic systems, forming highly sterically strained structures. This phenomenon correlates with reduced carborane rotation, as determined by DFT and NMR investigations. All carboranes studied are fluorescent, showing local emission (LE) from the aromatic moiety, however the ortho-carborane compounds also demonstrate multi-emissive behaviour, as the carborane introduces a delocalised emissive species, associated with intramolecular charge-transfer (ICT) and twisted-ICT (TICT) states, the latter of which occurs when the carboranyl C-C bond is perpendicular to the aromatic plane. By introducing phenyl groups to ortho-carborane, it was shown that the ground state could be tuned to favour TICT formation, through favourable π-π interactions between the aromatic substituents ‘locking’ the C-C bond in the perpendicular arrangement. Chrysene and phenanthrene-based ortho-carborane compounds were found to exhibit a peculiar, concentration-dependent, low-energy emissive peak. Through detailed temperature-dependent optical studies, these emissive excited states were assigned to excimers, the first time such species, involving a carborane in a charge-transfer state, has been observed. In aggregated states, formed in bad solvents, the PL intensity for the meta and para-carboranes is reduced, but for the ortho-carborane compounds the intensity increases enormously, as a result of aggregation-induced emission (AIE). AIE is determined to be as a result of TICT emissive species, where the excited state is localised inside ortho-carborane, reducing non-radiative decay routes and boosting PL quantum yield. The aggregates were directly imaged with a combination of scanning and transmission electron microscopy (SEM and TEM respectively) and were found to form spherical nanoparticles, with evidence of crystallinity.

description: We present results from two high-resolution hydrodynamical simulations of proto-cluster regions at z~2.1. The simulations have been compared to observational results for the socalled Spiderweb galaxy system, the core of a putative proto-cluster region at z = 2.16, found around a radio galaxy. The simulated regions have been chosen so as to form a poor cluster with M200~10^14 h-1 Msun (C1) and a rich cluster with M200~2x10^15 h-1 Msun (C2) at z = 0. The simulated proto-clusters show evidence of ongoing assembly of a dominating central galaxy. The stellar mass of the brightest cluster galaxy (BCG) of the C2 system is in excess with respect to observational estimates for the Spiderweb galaxy, with a total star formation rate which is also larger than indicated by observations. We find that the projected velocities of galaxies in the C2 cluster are consistent with observations, while those measured for the poorer cluster C1 are too low compared to the observed velocities. We argue that the Spiderweb complex resemble the high-redshift progenitor of a rich galaxy cluster. Our results indicate that the included supernovae feedback is not enough to suppress star formation in these systems, supporting the need of introducing AGN feedback. According to our simulations, a diffuse atmosphere of hot gas in hydrostatic equilibrium should already be present at this redshift, and enriched at a level comparable to that of nearby galaxy clusters. The presence of this gas should be detectable with future deep X-ray observations.

What is within the moment of hesitation?
Creators: name: Fionnachd-Fein, B
Publisher: name: University Of Tasmania
Year: 2023

description: This research project explores the question 'What is within the moment of hesitation?' The research question is an example of an emergent phenomenon. The phrase 'popped into my head' one day and, despite my best efforts, I was unable to identify where it came from. Its persistence prompted this experimental art-based research. Exploration of the question has suggested that a moment is not necessarily an instant, hesitation is not stasis. Instead, the question seems to point to a 'points of ellipsis' where the extent and structure of that which is 'missing' is unknown at the moment of encounter. It opens up the potential for infinite possibilities and complexity. Ephemeral and often formless, the works are prompted by the emergent phenomena of everyday life. Sometimes they are simply the recorded remainder of a moment, sometimes a performance, sometimes an invitation to others to do something (such as the participatory projects and Fluxus-inspired event scores). The role of these disparate and, in terms of the project's presentation, dispersed works is not to be a static form of art but to be indicators of potential, signifiers of possibilities. The video works in particular build on John Cage's expansion, in his work 4'33'', of the understanding of music to include sounds that are in the everyday environment.

Starting from a small-scale model for tracer particles trajectories, we derive the corresponding governing equations for the concentration of the mobile and immobile phases. We show that this formulation is fairly general and can easily take into account non-constant coefficients and in particular space-dependent sorption rates. The transport equations are solved numerically and a comparison with Monte Carlo particle-tracking simulations of spatial contaminant profiles and breakthrough curves is proposed, so to illustrate the obtained results.

By coupling the centers strongly to high-finesse optical photonic-bandgap cavities with modest quality factor Q = O(10^4) and small mode volume V = O(λ^3), these system can deliver picosecond single-photon pulses at their zero-phonon lines with probabilities of 0.954 (NE8) and 0.812 (SiV) under a realistic optical excitation scheme. The undesirable blinking effect due to transitions via metastable states can also be suppressed with O(10^{-4}) blinking probability. We analyze the application of these enhanced centers, including the previously-studied cavity-enhanced nitrogen-vacancy (NV) center, to long-distance BB84 quantum key distribution (QKD) in fiber-based, open-air terrestrial and satellite-ground setups. In this comparative study, we show that they can deliver performance comparable with decoy state implementation with weak coherent sources, and are most suitable for open-air communication.

description: We study computational problems arising from the iterated removal of weakly dominated actions in anonymous games. Our main result shows that it is NP-complete to decide whether an anonymous game with three actions can be solved via iterated weak dominance. The two-action case can be reformulated as a natural elimination problem on a matrix, the complexity of which turns out to be surprisingly difficult to characterize and ultimately remains open. We however establish connections to a matching problem along paths in a directed graph, which is computationally hard in general but can also be used to identify tractable cases of matrix elimination. We finally identify different classes of anonymous games where iterated dominance is in P and NP-complete, respectively.

description: We describe an ion-based cavity-QED system in which the internal dynamics of an atom is coupled to the modes of an optical cavity by vacuum-stimulated Raman transitions. We observe Raman spectra for different excitation polarizations and find quantitative agreement with theoretical simulations. Residual motion of the ion introduces motional sidebands in the Raman spectrum and leads to ion delocalization. The system offers prospects for cavity-assisted resolved-sideband ground-state cooling and coherent manipulation of ions and photons.

description: We derive some necessary conditions on a Riemannian metric $(M, g)$ in four dimensions for it to be locally conformal to Kähler. If the conformal curvature is non anti--self--dual, the self--dual Weyl spinor must be of algebraic type $D$ and satisfy a simple first order conformally invariant condition which is necessary and sufficient for the existence of a Kähler metric in the conformal class. In the anti--self--dual case we establish a one to one correspondence between Kähler metrics in the conformal class and non--zero parallel sections of a certain connection on a natural rank ten vector bundle over $M$. We use this characterisation to provide examples of ASD metrics which are not conformal to Kähler. We establish a link between the `conformal to Kähler condition' in dimension four and the metrisability of projective structures in dimension two. A projective structure on a surface $U$ is metrisable if and only if the induced (2, 2) conformal structure on $M=TU$ admits a Kähler metric or a para-Kähler metric.

description: Начало периода феодальной раздробленности на Руси неминуемо привело к разобщенности некогда политически консолидированного государственного тела Древней Руси на удельные княжества, которые, в свою очередь, усилили сепаратистские тенденции в целях увеличения объема личных суверенных прав местного удельного властителя в пределах подвластной ему административно-территориальной единицы «земли Русской». Данные децентрализованные процессы происходили при непосредственном участии местных иерархов церковных организации, которые фактически и сакрально-идеологически обосновывали возможность удельной легитимации политических амбиций удельных светских лидеров. Особая общественно-политическая ситуация сложилась в Новгородском княжестве.

description: We discuss and review several thermodynamic criteria that have been introduced to characterize the thermal stability of a self-correcting quantum memory. We first examine the use of symmetry-breaking fields in analyzing the properties of self-correcting quantum memories in the thermodynamic limit: we show that the thermal expectation values of all logical operators vanish for any stabilizer and any subsystem code in any spatial dimension. On the positive side, we generalize the results in [R. Alicki et al., arXiv:0811.0033] to obtain a general upper bound on the relaxation rate of a quantum memory at nonzero temperature, assuming that the quantum memory interacts via a Markovian master equation with a thermal bath. This upper bound is applicable to quantum memories based on either stabilizer or subsystem codes.

description: We compute the pair entanglement between two interacting bosons in a two dimensional (2D)isotropic harmonic trap. The interaction potential is modeled by a 2D regularized pseudo-potential. By analytically decomposing the wave function into the single particle basis, we show the dependency of the pair entanglement on the scattering length. Our results turn out to be in good agreements with earlier results using a quasi-2D geometry.

description: В современных демократических государствах политические права и свободы занимают особое место в иерархии конституционных прав, поскольку их реализация позволяет гражданам участвовать в управлении делами государства, выражать свои взгляды, отстаивать общественнополитические интересы. Благодаря политическим правам в настоящее время граждане и все гражданское общество в целом реализуют свои интересы непосредственно в осуществлении народовластия; а также определяют положение личности в современных политических отношениях. При этом политические права и свободы образуют условия, которые необходимы для укрепления взаимосвязи между человеком и обществом, а также гражданином и государством.

description: Within the framework of density functional theory we investigate the nature of magnetism in various families of Fe-based superconductors. (i) We show that magnetization of stripe-type antiferromagnetic order always becomes stronger when As is substituted by Sb in LaOFeAs, BaFe$_2$As$_2$ and LiFeAs. By calculating Pauli susceptibilities, we attribute the magnetization increase obtained after replacing As by Sb to the enhancement of an instability at $(π,π)$. This points to a strong connection between Fermi surface nesting and magnetism, which supports the theory of the itinerant nature of magnetism in various families of Fe-based superconductors. (ii) We find that within the family LaOFe$Pn$ ($Pn$=P, As, Sb, Bi) the absence of an antiferromagnetic phase in LaOFeP and its presence in LaOFeAs can be attributed to the competition of instabilities in the Pauli susceptibility at $(π,π)$ and $(0,0)$, which further strengthens the close relation between Fermi surface nesting and experimentally observed magnetization. (iii) Finally, based on our relaxed structures and Pauli susceptibility results, we predict that LaOFeSb upon doping or application of pressure should be a candidate for a superconductor with the highest transition temperature among the hypothetical compounds LaOFeSb, LaOFeBi, ScOFeP and ScOFeAs while the parent compounds LaOFeSb and LaOFeBi should show at ambient pressure a stripe-type antiferromagnetic metallic state.

Dimensions of ethnic education : the Japanese in British Columbia, 1880-1940
Creators: name: Hutchinson, Harold Keith
Publisher: name: University of British Columbia
Year: 2011

description: The role of education in the assimilation of British Columbia's Japanese population was significant. In the following pages an attempt has been made to describe and to assess this role. The investigation, however, is dependent upon the concept applied to the term assimilation. For the purpose of this study, assimilation was either structural or behavioral in nature. What this thesis demonstrates is that the public school was to a large extent responsible for the behavioral assimilation of the second generation Japanese. Moreover, the study shows that the first generation Japanese willingly promoted the utilization of the public school system by their children. The Issei were only too successful in this task for inevitably the Nisei, once they accepted the values advanced by the public schools, discarded many of the customs, manners and traditions of their parents. Because a study which involves only the public school system would provide too limited a scope, considerable attention was given to churches and Japanese institutions. For instance, the Christian church was the first major agency to establish a rapport with British Columbia's Japanese community. In time, the churches set up well organized programs to provide various forms of education to both first and second generation Japanese. On the other hand, an investigation of Japanese institutions reveals that many of them originally served to separate the Japanese from the greater community. As the years passed the roles of these institutions changed, an occurence most apparent with the Vancouver Japanese Language School. This school eventually became one of the primary acculturating agents in the Japanese community. Therefore, what this thesis reveals is the relationship between acculturation and selected (institutional) educational factors. It also examines the interaction of churches, Japanese institutions and the public school. Churches and Japanese institutions ran programs which originally substituted for public education. Later, this role changed to a complementary one. The thesis concludes that churches, Japanese institutions and public schools were, to varying degrees, responsible for the acculturation of the Japanese in British Columbia.

description: Основной функцией современной российской прокуратуры является осуществление прокурорского надзора. Все иные направления ее деятельности, за исключением уголовного преследования, обусловливаются осуществлением надзорной деятельности. Содержание прокурорского надзора составляет правозащитная и правоохранительная деятельность. По своей форме он представляет собой в большей степени не традиционное прокурорское наблюдение, а прокурорско-надзорный процесс, осуществляемый в различных формах и включающий несколько видов прокурорских производств.
