description: In this work, novel nematic monomer (M1), chiral monomer (M2) and crosslinker (CL) have been synthesised to form a series of side chain chiral liquid crystalline elastomers (ChLCEs) LCE1-LCE7 by graft copolymerisation with poly(methylhydrogeno)siloxane backbone. M1 and M2 were both dimer type with great length, and the chiral 2-octyl terminal group was seldom used in liquid crystal elastomer system. The chemical structures, thermal stability and LC phase behaviours of monomers, crosslinker and ChLCEs were examined by different experimental techniques. The helical structure of combining the chiral and achiral liquid crystalline side chains endowed the obtained ChLCEs with chiral nematic liquid crystalline properties. By changing the dosages of the crosslinker, the mesomorphic properties of ChLCEs could be adjusted. The mesophase-isotropic phase range of the ChLCEs were slightly broadened with increasing addition of CL according to the differential scanning calorimetry (DSC). The synthesised ChLCEs exhibited excellent thermal stability from thermal analysis (TG) results. The effective crosslink density (c) of the ChLCEs was characterised by swelling experiments showing the molecular weight between the crosslinking points decreasing with the increase of the CL. The FT-IR imaging system indicates the functional groups of all the ChLCEs are well distributed.
A New Kinetic Equation for Compton Scattering

description: A kinetic equation for Compton scattering is given that differs from the Kompaneets equation in several significant ways. By using an inverse differential operator this equation allows treatment of problems for which the radiation field varies rapidly on the scale of the width of the Compton kernel. This inverse operator method describes, among other effects, the thermal Doppler broadening of spectral lines and continuum edges, and automatically incorporates the process of Compton heating/cooling. It is well adapted for inclusion into a numerical iterative solution of radiative transfer problems. The equivalent kernel of the new method is shown to be a positive function and with reasonable accuracy near the intitial frequency, unlike the Kompaneets kernel, which is singular and not wholly positive. It is shown that iterates of the inverse operator kernel can be easily calculated numerically, and a simple summation formula over these iterates is derived that can be efficiently used to compute Comptonized spectra. It is shown that the new method can be used for initial value and other problems with no more numerical effort than the Kompaneets equation, and that it more correctly describes the solution over times comparable to the mean scattering time.

description: Realistic finite temperature simulations of matter are a formidable challenge for first principles methods. Long simulation times and large length scales are required, demanding years of compute time. Here we present an on-the-fly machine learning scheme that generates force fields automatically during molecular dynamics simulations. This opens up the required time and length scales, while retaining the distinctive chemical precision of first principles methods and minimizing the need for human intervention. The method is widely applicable to multi-element complex systems. We demonstrate its predictive power on the entropy driven phase transitions of hybrid perovskites, which have never been accurately described in simulations. Using machine learned potentials, isothermal-isobaric simulations give direct insight into the underlying microscopic mechanisms. Finally, we relate the phase transition temperatures of different perovskites to the radii of the involved species, and we determine the order of the transitions in Landau theory.

description: We present the high-resolution spectrum of the accretion-powered millisecond pulsar XTE J0929-314 during its 2002 outburst, measured using the Low Energy Transmission Grating Spectrometer onboard the Chandra X-ray Observatory. The 1.5-25.3 A (0.5-8.3 keV) Chandra spectrum is well fit by a power-law + blackbody model with photon index Gamma=1.55+/-0.03, blackbody temperature kT_bb=0.65+/-0.03 keV, and blackbody normalization R_bb,km/d_10kpc=7.6+/-0.8. No emission or absorption features are found in the high-resolution spectrum, with a 3 sigma equivalent width upper limit of <0.007 A at 1.5 A and <0.12 A at 24 A. The neutral absorption edge depths are consistent with the estimated interstellar absorption along the line of sight to the source. We found no orbital modulation of the 2-10 keV X-ray flux, to a 3 sigma upper limit of 1.1%, which implies an upper limit on the binary inclination angle of i<85deg for a Roche-lobe-filling companion. We also present the broadband spectrum measured over the course of the outburst by the Rossi X-ray Timing Explorer. The XTE spectrum of XTE J0929-314 is also well fit with a power-law + blackbody model, with average values of Gamma=1.76+/-0.03, kT_bb=0.66+/-0.06 keV, and R_bb,km/d_10kpc=5.9+/-1.3 in the 2-50 keV energy range. The blackbody flux remained constant over the course of the outburst, while the power-law flux was strongly correlated to the (decreasing) flux of the source. We find that the difference in power-law photon indices measured from Chandra and XTE spectra can be explained by a change in the power-law photon index at low energies.

description: Current quadratic smoothness energies for curved surfaces either exhibit distortions near the boundary due to zero Neumann boundary conditions, or they do not correctly account for intrinsic curvature, which leads to unnatural-looking behavior away from the boundary. This leads to an unfortunate trade-off: one can either have natural behavior in the interior, or a distortion-free result at the boundary, but not both. We introduce a generalized Hessian energy for curved surfaces, expressed in terms of the covariant one-form Dirichlet energy, the Gaussian curvature, and the exterior derivative. Energy minimizers solve the Laplace-Beltrami biharmonic equation, correctly accounting for intrinsic curvature, leading to natural-looking isolines. On the boundary, minimizers are as-linear-as-possible, which reduces the distortion of isolines at the boundary. We discretize the covariant one-form Dirichlet energy using Crouzeix-Raviart finite elements, arriving at a discrete formulation of the Hessian energy for applications on curved surfaces. We observe convergence of the discretization in our experiments.

COMPARISON
 The Bacchus Marsh Diprotodon assemblage is dominated by dentary and maxillary fragments, with at least 18 individuals represented. Interestingly, the assemblage is represented solely by small-form individuals (Fig. 8). Tooth eruption and wear patterns indicate that the assemblage is dominated by subadult to young adult individuals. Juvenile and mature individuals were not observed in the assemblage. The dentaries are morphologically similar to small-form individuals from the Darling Downs.
 More than 230 teeth were examined from the Bacchus Marsh Diprotodon assemblage. All teeth are morphologically similar to the corresponding teeth of the Darling Downs Diprotodon assemblage discussed above and thus do not warrant additional description. The mean dimensions of most cheek teeth are smaller than corresponding teeth of all other undifferentiated size class localities examined in this study (Tables 2, 3). However, most means overlap at one standard deviation, and all overlap at two standard deviations (Tables 2, 3). Mean tooth dimensions of the Bacchus Marsh Diprotodon small-form assemblage are similar Mean (standard deviation, coefficient of variation). ‘All localities’ combines the Darling Downs, Bacchus Marsh, Lake Callabonna, Myall Creek, Lancefield Swamp and Reddestone Creek data sets, as well as morphometric data for specimens from other localities available for study.

description: LAKE CALLABONNA DIPROTODON
DENTAL MORPHOMETRIC AND MORPHOLOGICAL
COMPARISON
 Both size classes of Diprotodon are undoubtedly represented in the Lake Callabonna Diprotodon assemblage (Fig. 8). More than 100 teeth were investigated from the deposits. Both dentary and tooth morphology are similar to that of the Darling Downs, Reddestone Creek and Myall Creek Diprotodon assemblages and thus do not warrant additional description.
 The mean dimensions of most cheek teeth are similar to those of other assemblages examined in this study, and most means overlap at one standard deviation (Tables 2, 3). However, the mean dimensions of some teeth from the Lake Callabonna assemblage are 5–6% larger than corresponding teeth of other assemblages (e.g. M 4; Table 2). In the case of the M 4, the mean is based on a small sample size (N = 6). The dimension of the M 4 is similar to Mean (standard deviation, coefficient of variation). ‘All localities’ combines the Darling Downs, Bacchus Marsh, Lake Callabonna, Myall Creek, Lancefield Swamp and Reddestone Creek data sets, as well as morphometric data for specimens from other localities available for study.
 that of the large form from the Darling Downs (Tables 1–3). Thus, such results may be the product of sampling bias; those teeth could conceivably be solely represented by the large-form Diprotodon, therefore skewing the mean. Dimensions of other teeth from the Lake Callabonna assemblage do not vary more than 1–2% in comparison with other assemblages (Tables 2, 3). Additionally, there is an observable morphometric overlap in teeth size between large- and small-form Lake Callabonna Diprotodon (Fig. 11).

We also show how the same finite dimensional quantum group acts on the space of generalized differential forms defined as the reduced Wess Zumino complex associated with the algebra M.

title: A case study of students' attitudes towards ANNESTs and ANNESTs' reflections on their language teaching practice

Year: 2019
Subjects: subject: Teaching
subject: Rote learning

subject: ANNEST

description: For English-language students, the dominant preference is to have native English- speaking teachers (NESTs). This is because NESTs are perceived as the ideal teachers for learning English given that it is their first language. NESTs have the “gold standard” of pronunciation and grammatical correctness, so they are perceived to be more qualified than non-native English-speaking teachers (NNESTs). On the other hand, Asian Non- Native English-speaking teachers (ANNESTs) tend to be regarded as deficient speakers with poor pronunciation and lack of knowledge of western culture, even though ANNESTs have been found to be competent at grammar and test-centered training (Walkinshaw & Oanh, 2014). To examine whether this is the case in Australia, this study aims to investigate the attitudes of English as an Additional Language (EAL) students towards ANNESTs in ELICOS programs, and how ANNESTs reflect on their language teaching practice based on EAL students’ attitudes. For this research, case study research was employed to collect data from EAL students and ANNESTs in an English language school in a city in South East Queensland. In this study, the researcher used a quantitative approach (questionnaire survey) to establish EAL students’ attitudes towards ANNESTs, and a qualitative approach (semi-structured interviews with students and ANNESTs’ respectively) to examine how ANNESTs reflect on their language teaching practice based on EAL students’ attitudes. Quantitative data gathered from the survey was analysed using Excel software to obtain English students’ attitudes towards ANNESTs, and qualitative data were analysed using thematic analysis to gain insights into how ANNESTs face challenges and build their identities in Australia. The qualitative and quantitative results were then triangulated to form a complete whole. The findings of this research provide evidence of initial negative attitudes of EAL students towards ANNESTs in the ten-week ELICOS program, followed by positive attitudes towards ANNESTs’ on-going language instruction. Overall, EAL students showed positive attitudes towards ANNESTs regarding their language instruction in the ELICOS program; this positive attitude increased ANNESTs’ self-esteem and enhanced their identity. It was also interesting to note that the pronunciation taught by ANNESTs was evaluated as positive, which contradicted previous studies that have found the accented pronunciation of NNESTs (including ANNESTs) was frowned upon (e.g., Butler, 2007; Goto Butler, 2007; Gu, 2011).

description: We present analytical and numerical simulation results for squeezing, entanglement, and quantum discord in a dissipatively coupled coherent Ising machine (CIM). Both analytical solutions and numerical simulation results, which are obtained with positive-P, truncated-Wigner and truncated-Husimi representations for the density operator, predict the presence of entanglement and quantum discord, below and above the threshold of CIM. The entanglement criteria and quantum discord are evaluated as a function of the dissipative coupling strength relative to the background loss. For coupled two DOPOs, while entanglement disappears as the background loss exceeds the Ising coupling strength, the quantum discord remains finite even with a large linear loss. For one-dimensional lattice of DOPOs, while entanglement disappears for DOPO pair with large distance, quantum discord remains finite.

COMPARISON
 There were no well-preserved dentaries or maxillae in the Myall Creek Diprotodon assemblage to allow comprehensive description or comparison with other localities. The single dentary available for study (AMF 49681) belonged to a large-form individual that is morphologically similar to large-form individuals from other assemblages examined.
 Over 160 teeth were examined from the assemblage. Tooth morphology is similar to that of all other Diprotodon assemblages examined in this study, and thus does not warrant additional description. Like the Darling Downs assemblage, P 3 morphology is particularly variable in cusp, cingula and shape expression (Fig. 12). The means of cheek teeth dimensions are similar to those of corresponding teeth of other Diprotodon assemblages, and all means overlap at one standard deviation (Tables 2, 3).

description: The integration of kinetic effects in fluid models is important for global simulations of the Earth's magnetosphere. We use a two-fluid ten moment model, which includes the pressure tensor and has been used to study reconnection, to study the drift kink and lower hybrid drift instabilities. Using a nonlocal linear eigenmode analysis, we find that for the kink mode, the ten moment model shows good agreement with kinetic calculations with the same closure model used in reconnection simulations, while the electromagnetic and electrostatic lower hybrid instabilities require modeling the effects of the ion resonance using a Landau fluid closure. Comparisons with kinetic simulations and the implications of the results for global magnetospheric simulations are discussed.

description: Using a combination of micromechanical force and flowloop measurements, hydrate deposition on a pipe wall surface was investigated for ‘dry’ hydrates formed in the bulk phase and for hydrates growing on the pipe surface. Cyclopentane ‘dry’ hydrates (without a free water phase) were used to predict whether hydrates, formed in a bulk condensate phase, would adhere to a pipe wall. Adhesion forces between cyclopentane hydrates and steel were measured using a micro-mechanical force apparatus. The average force of adhesion was measured to be very small, less than 0.01 N/m. This force was used in a particle force balance, predicting that hydrates formed in the bulk phase would not deposit on the pipe wall. It was hypothesized than in the presence of a water saturated hydrocarbon, hydrates would grow on the pipe wall as the fluid cooled below its equilibrium temperature. This hypothesis was confirmed using a single pass condensate flowloop. Water was continuously dissolved into the flowloop inlet stream as water deposited in the flowloop test section, resulting in both a pressure drop and fluid temperature increase. This work illustrates the need for a hydrate wall growth model.

description: Regional variation in climate can generate differences in population dynamics and stage structure. Where regional differences exist, the best approach to pest management may be region-specific. Salmon lice are a stage-structured marine copepod that parasitizes salmonids at aquaculture sites worldwide, and have fecundity, development and mortality rates that depend on temperature and salinity. We show that in Atlantic Canada and Norway, where the oceans are relatively cold, salmon lice abundance decreases during the winter months, but ultimately increases from year to year, while in Ireland and Chile, where the oceans are warmer, the population size grows monotonically without any seasonal declines. In colder regions, during the winter the stage structure is dominated by the adult stage, which is in contrast to warmer regions where all stages are abundant year round. These differences translate into region-specific recommendations for management: regions with slower population growth have lower critical stocking densities, and regions with cold winters have a seasonal dependence in the timing of follow-up chemotherapeutic treatments. Predictions of our salmon lice model agree with empirical data, and our approach provides a method to understand the effects of regional differences in climate on salmon lice dynamics and management.

description: LANCEFIELD SWAMP DIPROTODON
DENTAL MORPHOMETRIC AND MORPHOLOGICAL
COMPARISON
 The Diprotodon assemblage is represented by dentary and maxillary fragments, but is dominated by isolated teeth. Both size classes are undoubtedly represented in the deposit and the ratio of largeto small-form individuals is approximately 1:1. One dentary (NMVP151805-6) represents a juvenile small-form individual. The individual appears to be of similar morphological age to the juvenile largeform individual (QMF6633; Fig. 9F) from the Darling Downs (as determined by similar molar eruption patterns). The Lancefield Swamp specimen lacks the distinctive ‘chin’; the ventral margin of the horizontal ramus is more convex; and the posterior portion of the dentary is curved, similar to that of more mature individuals. Generally, from the limited number of dentaries available, no specific morphological differences were observed in comparison with either large- and/or small-form individuals of the Darling Downs, Bacchus Marsh and Lake Callabonna assemblages. Some dentaries show evidence of abrasion, possibly suggesting post-mortem fluvial transport.
 More than 70 teeth were examined in the Lancefield Swamp collection. Tooth morphologies are identical to those of all other aforementioned localities, and thus do not warrant additional description. As the assemblage is dominated by isolated teeth, it is not possible to assign the majority of teeth to specific size classes. The mean molar teeth dimensions vary little in comparison with other assemblages, and the means overlap at less than one standard deviation for most measurements (Tables 2, 3). However, similar to aforementioned examples from the Lake Callabonna Diprotodon assemblage, some teeth (e.g. P 3 and M 4) are larger than corresponding teeth in other populations. However, like those from Lake Callabonna, such teeth are represented by few specimens, and for reasons described above, the differences are probably the result of sampling biases.

description: We study the geometric significance of Leinster's magnitude invariant. For closed manifolds we find a precise relation with Brylinski's beta function and therefore with classical invariants of knots and submanifolds. In the special case of compact homogeneous spaces we obtain an elementary proof that the residues of the beta function contain the same geometric information as the asymptotic expansion of the magnitude function. For general closed manifolds we use the recent pseudodifferential analysis of the magnitude operator to relate these via an interpolating polynomial family. Beyond manifolds, the relation with the Brylinski beta function allows to deduce unexpected properties of the magnitude function for the $p$-adic integers.

description: REDDESTONE CREEK DIPROTODON
DENTAL MORPHOMETRIC AND MORPHOLOGICAL
COMPARISON
 The Reddestone Creek Diprotodon assemblage is similar to that of the Myall Creek assemblage in that most of the material is represented by isolated teeth rather than dentaries or maxillae. Almost 50 Diprotodon teeth (mostly isolated) were examined from the assemblage. Reddestone Creek Diprotodon teeth are morphologically similar to those of other assemblages examined and do not warrant additional description. The means for most measurements of molar dimensions vary less than 1–2% in comparison with those of the Darling Downs, and the means overlap at less than one standard deviation (Tables 2, 3).

Medicine murder of people with albinism in Tanzania – how casino capitalism creates rumorscapes and occult economies

description: In 2007, a spate of killings of people with albinism in Northwest Tanzania placed the country in the international limelight. Rumors that the bones of people with albinism were a necessary ingredient in wealth generating magic potions provoked the killings which had no precedents in Tanzania or the local Sukuma culture. This working paper places the rumors in a wider context of living with albinism in Tanzania as well as a general retreat to magic in the face of economic distress. It is argued that the specific nature of the mining and fishing industries in Northwest Tanzania as examples of casino capitalism brings about ‘rumorscapes’, in which stories from near and far are exchanged, fused, adapted and, by some ‘witchdoctors’, turned into viable business options. The rumors and the killings must be understood as a new phenomenon, not as a retreat to traditional modi operandi from local Sukuma magic. Only by addressing the uncertainties faced by people working in the fishing and mining industries will it be possible to prevent such murders in the future.
description: Im Jahr 2007 zog Tansania durch eine Serie an Mordfällen an Menschen mit Albinismus in Nordwesttansania international Aufmerksamkeit auf sich. Gerüchte, dass die Knochen der Menschen mit Albinismus ein zwingender Bestanteil von magischen Mitteln, die Reichtum versprachen, seien, provozierten diese Morde, die keine Vorläufer in Tansania oder der lokalen Ethnie der Sukuma hatten. Dieses Working Paper erläutert die Entstehung der Gerüchte vor dem Hintergrund, was es bedeutet, in Tansania mit Albinismus zu leben und untersucht sie im Hinblick auf eine häufiger auftretende Tendenz, sich angesichts ökonomischer Unsicherheit auf Magie zu besinnen. Es wird argumentiert, dass die Besonderheiten des Bergbaus und des Fischfangs als ‚casino capitalism‘ ein internationales Fluidum an Gerüchten (‚rumorscape‘) entstehen lassen, innerhalb dessen Geschichten von nah und fern ausgetauscht, fusioniert, adaptiert und von einigen ‚witchdoctors‘ zu erträglichen Geschäftsmodellen gemacht werden. Die Gerüchte und Morde müssen als neues Phänomen begriffen werden, nicht als eine Rückbesinnung auf traditionelle modi operandi der Magie der lokalen Sukuma. Erst, wenn die Unsicherheiten der Leute, die im Bergbau und Fischfang arbeiten, beseitigt werden, wird es möglich sein, solche Morde in Zukunft zu verhindern.

description: We report a combined microscopy and spectroscopy study of Au deposited on the Bi2Se3(0001) single crystal surface. At room temperature Au forms islands, according to the Volmer-Weber growth mode. Upon annealing to 100° C the Au deposits are not stable and assemble into larger and thicker islands. The topological surface state of Bi2Se3 is weakly affected by the presence of Au. Contrary to other metals, such as Ag or Cr, a strong chemical instability at the Au/Bi2Se3 interface is ruled out. Core level analysis highlights Bi diffusion toward the surface of Au islands, in agreement with previous findings, while chemical interaction between Au and atomic Se is limited at the interfacial region. For the investigated range of Au coverages, the Au/Bi2Se3 heterostructure is inert towards CO and CO2 exposure at low pressure (10-8 mbar) regime.

description: Bei der Ermittlung der Kapitalkosten nicht börsennotierter Unternehmen wird üblicherweise auf Beta-Faktoren gehandelter Vergleichsunternehmen zurückgegriffen. Um diese an die Kapitalstruktur des Bewertungsobjekts anzupassen, wird ein funktionaler Zusammenhang zwischen dem Beta-Faktor eines verschuldeten und eines unverschuldeten Unternehmens benötigt. Wir zeigen, dass die in der Praxis weitgehend angewandte Modigliani-Miller- Anpassungsformel logische Inkonsistenzen enthält, und befürworten bei marktwertorientierter Finanzierung die Verwendung der Miles-Ezzell-Anpassung.

description: We report the discovery of a new, bright (V = 17 mag) AM Her system as the optical counterpart of the soft ROSAT All-Sky-Survey source RX J1846.9+5538 (= 1RXS J184659.4+553834). Optical photometric and spectroscopic follow-up observations reveal a single period of 128.7 min, consistent with a high degree of spin-orbit synchronization, and a low polar field strength ($B<20$ MG) of the primary accretion region. The system was observed in optical intermediate and high states that differ by about 1 mag. These brightness variations were accompanied by a correlated change of the optical light curve, which we interpret as a switch between one- and two-pole accretion. This explanation is also supported by the X-ray light curves, which at two different epochs display emission from two equally bright accretion regions separated by 160 degrees. Both spots possess distinct spectral X-ray properties as seen from the X-ray hardness ratio, where the secondary accretion region appears significantly softer, thus probably indicating a higher field strength compared to the primary region. In all ROSAT pointings a deep dip is present during the primary flux maxima, very likely caused by absorption in one of the accretion streams.

Quantum Coherence, Coherent Information and Information Gain in Quantum Measurement

description: A measurement is deemed successful, if one can maximize the information gain by the measurement apparatus. Here, we ask if quantum coherence of the system imposes a limitation on the information gain during quantum measurement. First, we argue that the information gain in a quantum measurement is nothing but the coherent information or the distinct quantum information that one can send from the system to apparatus. We prove that the maximum information gain from a pure state, using a mixed apparatus is upper bounded by the initial coherence of the system. Further, we illustrate the measurement scenario in the presence of environment. We argue that the information gain is upper bounded by the entropy exchange between the system and the apparatus. Also, to maximize the information gain, both the initial coherence of the apparatus, and the final entanglement between the system and apparatus should be maximum. Moreover, we find that for a fixed amount of coherence in the final apparatus state the more robust apparatus is, the more will be the information gain.
