description: Sentinel-2 multi-spectral images collected over periods of several months were used to estimate vegetation height for Gabon and Switzerland. A deep convolutional neural network (CNN) was trained to extract suitable spectral and textural features from reflectance images and to regress per-pixel vegetation height. In Gabon, reference heights for training and validation were derived from airborne LiDAR measurements. In Switzerland, reference heights were taken from an existing canopy height model derived via photogrammetric surface reconstruction. The resulting maps have a mean absolute error (MAE) of 1.7 m in Switzerland and 4.3 m in Gabon (a root mean square error (RMSE) of 3.4 m and 5.6 m, respectively), and correctly estimate vegetation heights up to >50 m. They also show good qualitative agreement with existing vegetation height maps. Our work demonstrates that, given a moderate amount of reference data (i.e., 2000 km$^2$ in Gabon and $\approx$5800 km$^2$ in Switzerland), high-resolution vegetation height maps with 10 m ground sampling distance (GSD) can be derived at country scale from Sentinel-2 imagery.

description: We present the first results of the BIMA Survey of Nearby Galaxies (BIMA SONG), an imaging survey of the CO J=(1-0) emission in 44 nearby spiral galaxies at a typical resolution of 6". BIMA SONG differs from previous high-resolution CO surveys in that: (1) CO brightness was not an explicit selection criterion; (2) a larger area (200" diameter for most galaxies) of each galaxy was imaged; and (3) fully-sampled single-dish CO data (55" resolution) were obtained for over half of the sample galaxies, so all of the CO flux is imaged in these galaxies. The radial distribution of stellar light in galactic disks is generally characterized as an exponential. It is, therefore, of interest to investigate whether the molecular gas, which is the star-forming medium, has a similar distribution. Though our low-resolution single-dish radial profiles of CO emission can be described by simple exponentials, this is not true for the emission at our full 6" resolution. The scale lengths of the CO disks are correlated with the scale lengths of the stellar disks with a mean ratio of the scale lengths of about one. We also find that:(1) there is also a weak correlation between the ratio of K-band to CO luminosity and Hubble type; (2) in half of the galaxies presented here, CO emission does not peak at the location of the stellar nucleus; (3) averaged over the inner kiloparsec, the CO emission in one-half of the galaxies exhibits an excess over that expected from an exponential disk which is similar to the excess in stellar light caused by the bulge stars; and (4) this excess CO emission may be due to an increase in the total molecular gas content in the bulge region, or alternatively, to an increase in the CO emissivity caused by the increased pressure of the bulge region.

description: We present initial results from a wide-field, multi-colour imaging project, designed to study galaxy evolution in X-ray selected clusters at intermediate (z~0.25) and high redshifts (z~0.5). In this paper we give blue galaxy fractions from eight X-ray selected clusters, drawn from a combined sample of three X-ray surveys. We find that all the clusters exhibit excess blue galaxy populations over the numbers observed in local systems, though a large scatter is present in the results. We find no significant correlation of blue fraction with redshift at z>0.2 although the large scatter could mask a positive trend. We also find no systematic trend of blue fraction with X-ray luminosity. We show that the blue fraction is a function of (a) radius within a cluster, (b) absolute magnitude and (c) the passbands used to measure the colour. We find that our blue fractions (f_b) from galaxy colours close to restframe (U-B), f_b~0.4, are systematically higher than those from restframe (B-V) colours, f_b~0.2. We conclude this effect is real, may offer a partial explanation of the widely differing levels of blue fraction found in previous studies and may have implications for biases in optical samples selected in different bands. While the increasing blue fraction with radius can be interpreted as evidence of cluster infall of field galaxies, the exact physical processes which these galaxies undergo is unclear. We estimate that, in the cores of the more massive clusters, galaxies should be experiencing ram--pressure stripping of galactic gas by the intra--cluster medium. The fact that our low X-ray luminosity systems show a similar blue fraction as the high luminosity systems, as well as a significant blue fraction gradient with radius, implies other physical effects are also important.

description: The strong emphasis on ensuring a secure water supply for the population of Australia has been brought to light by the increasing frequency, severity and duration of drought events throughout the nation. This has forced State and Local government to implement alternative water supply strategies. These measures include water restrictions, campaigns to lower water consumption, and construction of new infrastructure including pipelines, improvements to stormwater and wastewater management, and desalination plants. In the urban water planning and management industry, these initiatives are relied upon to provide alternative potable supply types and reduce average daily water demand. However, understanding the actual potable water savings attributed to water demand management and source substitution initiatives requires the application of end use water consumption monitoring due to the need to establish the point of source savings related to these measures.

description: Nowadays, commonly used Resistive Plate Chambers (RPCs) have counting rate capabilities of ~10E4Hz/cm2 and position resolutions of ~1cm. We have developed small prototypes of RPCs (5x5 and 10x10cm2) having rate capabilities of up to 10E7Hz/cm2 and position resolutions of 50 micron("on line" without application of any treatment method like "center of gravity"). The breakthrough in achieving extraordinary rate and position resolutions was only possible after solving several serious problems: RPC cleaning and assembling technology, aging, spurious pulses and afterpulses, discharges in the amplification gap and along the spacers. High-rate, high-position resolution RPCs can find a wide range of applications in many different fields, for example in medical imaging. RPCs with the cathodes coated by CsI photosensitive layer can detect ultraviolet photons with a position resolution that is better than ~30 micron. Such detectors can also be used in many applications, for example in the focal plane of high resolution vacuum spectrographs or as image scanners.

description: The Cosmological Principle states that the Universe is statistically isotropic and homogeneous on large scales. In particular, this implies statistical isotropy in the galaxy distribution, after removal of a dipole anisotropy due to the observer's motion. We test this hypothesis with number count maps from the NVSS radio catalogue. We use a local variance estimator based on patches of different angular radii across the sky and compare the source count variance between and within these patches. In order to assess the statistical significance of our results, we simulate radio maps with the NVSS specifications and mask. We conclude that the NVSS data is consistent with statistical isotropy.

title: Reimagining My Music Creation: A Polymodular Synthesis A portfolio of three compositions and exegesis

Subjects: subject: Synthesizers
subject: opera
subject: score-oriented composer
subject: synthesizer-oriented composer-performer

description: Synthesizers changed the way I hear and understand sound, revealing surprising synergies between the electronic oscillator, the world of music I had known up until that time, and the natural world which has always inspired my musical thinking and creation. In embracing the synthesizer, my music was altered in ways that go beyond the adjustments made in re-conceiving a work for different forces. By virtue of their intrinsic and unique nature, synthesizers challenged and then modulated my thinking about every aspect of my music creation from idea, thematic development, form and orchestration through to realisation. This submission presents an opera recorded and explored during the research period and two multi-movement works composed and recorded during the research period. The exegesis outlines the journey undertaken from my work as a score-oriented composer of music for acoustic orchestral instrumentalists and vocalists, to my work as a synthesizer-oriented composer-performer of my music for electronic instruments. The evolving story contained in the musical works composed as the primary dimension of my research is strongly autobiographical. Accordingly, an autoethnographical methodology complements the foundational methodology of research led by artistic practice. The challenges involved in this journey were conceptual, technical, aesthetic, and methodological. This exegesis examines these various lines of development via the three works in the portfolio and, with reference to the scores, videos and recordings, the artistic responses and solutions resulting from my research. Excerpts of other works are offered as points of reference where relevant. Ultimately the work is examined for evidence of a polymodular synthesis between art, science and technology, forged in the creation of the music. Future creative potential for the candidate is considered, and to music composition more broadly in the electronic, digital age.

description: Motivated by the recent experimental observation of the topological Anderson insulator in disordered atomic wires based on the Su-Schrieffer-Heeger (SSH) model, we study disorder effects on a dimerized Kitaev superconductor chain which is regarded as the superconductor version of the SSH model. By computing the real-space winding number and the zero-bias differential conductance, we analyze the topological phase transitions occurring in a dimerized Kitaev superconductor chain with disorder. It is found that disorder can induce a topologically nontrivial superconductor phase hosting Majorana zero modes (MZMs). We can regulate the appearance of disorder-induced MZMs by adjusting the dimerization parameter. Finally, we use the self-consistent Born approximation method to verify the numerical results.

description: We describe a concept for a NASA SMEX Mission in which Gas Electron Multiplier (GEM) detectors, developed at CERN, are adapted for use in X-ray astronomy. These detectors can be used to obtain moderately large detector area and two-dimensional photon positions with sub mm accuracy in the range of 1.5 to 15 keV. We describe an application of GEMs with xenon gas, coded mask cameras, and simple circuits for measuring event positions and for anticoincidence rejection of particle events. The cameras are arranged to cover most of the celestial sphere, providing high sensitivity and throughput for a wide variety of cosmic explosions. At longer timescales, persistent X-ray sources would be monitored with unprecedented levels of coverage. The sensitivity to faint X-ray sources on a one-day timescale would be improved by a factor of 6 over the capability of the RXTE All Sky Monitor.

description: We compute the real-space profile of the superconducting order parameter (OP) in a hybrid ring that consists of a 1D superconductor connected to a Fibonacci chain using a self-consistent approach. In our study, the strength of the penetration, as measured by the order parameter at the center of the quasicrystal, depends on the structural parameter $ϕ$, or phason angle, that characterizes different realizations of the Fibonacci chains of a given length. We show that the penetration strength dependence on $ϕ$ reflects properties of the topological edge states of the Fibonacci chain. We show that the induced superconducting order parameter averaged over all chains has a power law decay as a function of distance from the S-N interface. More interestingly, we show that there are large OP fluctuations for individual chains and that the penetration strength in a finite Fibonacci chain can be significantly $larger$ than in a normal periodic conductor for special values of $ϕ$.

Los educadores frente a este reto que se les presenta en la nueva cotidianidad han tratado de paliar mediante distintas estrategias que van desde la recomendación de ubicarles en escuelas con currículos etnoeducativos o la adopción de mecanismos en los que la integración a la vida escolar subsume los aspectos identitarios, buscando la homogenización y la adaptación ocasionando la pérdida paulatina de las expresiones de riqueza cultural ancestral derivada de la imposición desde las prácticas escolares, de patrones de conducta ajenos a la naturaleza de los pueblos originarios. En este sentido, se ha venido adelantando una propuesta de investigación basada en el antecedente de dos proyectos desarrollados con jóvenes escolares de las etnias Wayúu y Emberá Katío del departamento de la Guajira y del Alto Sinú en el Departamento de Córdoba – Colombia

Subjects: Crystallography

description: Andrew Lang will be remembered internationally for having developed the technique of X-ray topography which enables individual defects, such as dislocations, stacking faults, small angle boundaries and magnetic domains, to be imaged in many different types of materials. His interests spanned the whole range of dislocation studies and he made many important contributions to advanced instrumentation for X-ray crystallography, including pioneering experiments with a synchrotron radiation source. His career began during the last year of the Second World War when he was appointed to a research position at the Unilever Research Laboratories at Port Sunlight, Cheshire. He held research positions at the University of Cambridge, where he completed his PhD, and after a period at the Philips Laboratory in Irvington-on-Hudson in the USA, he obtained a tenured post at Harvard University. He returned to the UK in 1959 as a lecturer at Bristol University, where he was to remain for the rest of his life, being successively promoted to reader and then professor.
Double-heavy axial-vector tetraquark $T_{bc;\bar{u}\bar{d}}^{0}$

description: The mass and coupling of the axial-vector tetraquark $T_{bc;\bar{u}\bar{d} }^{0}$ (in a short form $T_{bc}^{0}$) are calculated by means of the QCD two-point sum rule method. In computations we take into account contributions arising from various quark, gluon and mixed vacuum condensates up to dimension 10. The central value of the mass $m=(7105 \pm 155)~\mathrm{ MeV}$ lies below the thresholds for the strong and electromagnetic decays of $T_{bc}^{0}$ state, and hence it transforms to conventional mesons only through the weak decays. In the case of $m=7260~\mathrm{MeV}$ the tetraquark $T_{bc}^{0}$ becomes the strong- and electromagnetic-interaction unstable particle. In the first case, we find the full width and mean lifetime of $ T_{bc}^{0}$ using its dominant semileptonic decays $T_{bc}^{0}\to T_{cc;\bar{ u}\bar{d}}^{+}l\overline{ν}_{l}$ ($l=e,\ μ, τ$), where the final-state tetraquark is a scalar state. We compute also partial widths of the nonleptonic weak decays $T_{bc}^{0}\to T_{cc;\bar{u}\bar{d} }^{+}π^{-}(K^{-}, D^{-}, D_{s}^{-})$, and take into account their effects on the full width of $T_{bc}^{0}$. In the context of the second scenario we calculate partial widths of $S$-wave strong decays $T_{bc}^{0}\to B^{\ast -}D^{+}$ and $T_{bc}^{0}\to \overline{B}^{\ast 0}D^{0}$, and using these channels evaluate the full width of $T_{bc}^{0}$. Predictions for $Γ_{ \mathrm{full}} =(3.98\pm 0.51)\times 10^{-10}~\mathrm{MeV}$ and mean lifetime $τ=1.65_{-0.18}^{+0.25}~\mathrm{ps}$ of $T_{bc}^{0}$ obtained in the context of the first option, as well as the full width $Γ_{\mathrm{ full}}=(63.5\pm 8.9)~\mathrm{MeV}$ extracted in the second scenario may be useful for experimental and theoretical exploration of double-heavy exotic mesons.

description: In years to come, we shall see substantial progress in our understanding of nuclear structure - a rich and many-faceted field. An important element in this task will be to extend the study of nuclei into new domains. The journey to 'the limits' of isospin, angular momentum, and mass and charge is a quest for new and unexpected phenomena which await us in uncharted territories. What is extremely important from a theoretical point of view is that the new data are also expected to bring qualitatively new information about the effective nucleon-nucleon interaction and hence about the fundamental properties of the nucleonic many-body system. The main objective of this presentation is to discuss some of the challenges and opportunities for nuclear structure research with radioactive nuclear beams.

 Lectotype (designated here):— INDIA, Tamil Nadu, Coimbatore, Bolampatti Hills, 5000ft, Jan, Beddome s. n. (K barcode K000756499 [digital image!]). Fig.1
 Clarke (1882) described E. adnata based on manuscript publication of Beddome (1872) from ‘Forester Manual of Botany’ in J.D. Hooker’s Flora. Clarke has cited the specimen of E. adnata which was collected by Beddome from 5000 ft. at Bolampatti hills in flowering condition. A major part of Beddome’s collection is available in BM, some types at K and further materials at CAL (Stafleu & Cowan 1976). All the three herbaria were consulted (virtually and by contacting the curators). Providentially, we traced two specimens mounted on same sheet with separate barcode (K000756499 & K000756500) both collected by Beddome from two different localities. The specimen mounted on top of the sheet (K000756499) with a flowering twig, was collected in January from 5000 ft of Bolampatti hills, Tamil Nadu whereas the specimen at bottom (K000756500) depicts vegetative twig collected from Palghat hills, Kerala. As the type locality and the specimen K000756499 (K) matches with the protologue, we designate the specimen as lectotype for the name E. adnata.

description: We have developed and successfully used several innovative designs of detectors with solid photocathodes. The main advantage of these detectors is that rather high gains (>10E4) can be achieved in a single multiplication step. This is possible by, for instance, exploiting the secondary electron multiplication and limiting the energy of the steamers by distributed resistivity. The single step approach also allows a very good position resolution to be achieved in some devices: 50 micron on line without applying any treatment method (like center of gravity). The main focus of our report is new fields of applications for these detectors and the optimization of their designs for such purposes.

On the origin of the distribution of binary-star periods

Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Pre-main sequence and main-sequence binary systems are observed to have periods, P, ranging from one day to 10^(10) days and eccentricities, e, ranging from 0 to 1. We pose the problem if stellar-dynamical interactions in very young and compact star clusters may broaden an initially narrow period distribution to the observed width. N-body computations of extremely compact clusters containing 100 and 1000 stars initially in equilibrium and in cold collapse are preformed. In all cases the assumed initial period distribution is uniform in the narrow range 4.5 < log10(P) < 5.5 (P in days) which straddles the maximum in the observed period distribution of late-type Galactic-field dwarf systems. None of the models lead to the necessary broadening of the period distribution, despite our adopted extreme conditions that favour binary--binary interactions. Stellar-dynamical interactions in embedded clusters thus cannot, under any circumstances, widen the period distribution sufficiently. The wide range of orbital periods of very young and old binary systems is therefore a result of cloud fragmentation and immediate subsequent magneto-hydrodynamical processes operating within the multiple proto-stellar system.

title: Safe Food in Bangladesh: Perception and Influences on Safe Food Purchasing
Creators: name: Hossain, Rakia
Publisher: name: Griffith University

Subjects: subject: unsafe food
subject: food contamination
subject: food adulteration
subject: purchasing behaviour

description: Unsafe food is a global concern as it causes significant health risks to a large number of people. It has many and varied short and long-term health impacts such as salmonellosis, shigellosis, typhoid fever and even cancer. Therefore, safe food is the central concern for all stakeholders in the food system from producers to the marketplace to the household where the food is finally consumed. As an end point of the food safety chain, consumers demonstrate various strategies to ensure safe food from purchasing to consumption. Consumers’ food purchasing behaviour is greatly influenced by culture, economy, psychology and lifestyle. Therefore, understanding consumer attitude towards safe food is an important aspect for ensuring safe food and reducing foodborne illnesses in a community. In developing countries like Bangladesh, food contamination and the food adulteration situation are widely known public health issues as well as concerns of growing importance in recent times. However, very little is known about consumer safe food purchasing behaviour in Bangladesh. Hence, this current research attempts to explore primary household food purchasers’ (PHFP) perception of safe food, their information sources of safe food knowledge and application of this knowledge when purchasing safe foods. To evaluate these, the current study applied a mixed method approach where quantitative surveys and qualitative focus group discussions were used as data collection methods. The findings of the study revealed that the primary household food purchaser (PHFP) was more concerned about the usage of chemicals in food and they reported considering chemical food hazards during food purchasing. Among other safe food purchasing factors freshness was found as one of the most important factors. Besides freshness, the PHFP considered appearance, taste, colour, seasonality, origin of the product and expiry date, as features to guide safe food purchasing. More than 50% of the PHFP reported that` safe food has not been diminished in the last five years in Bangladesh. Most of the PHFP relied on friends and family members as their information sources for safe food purchasing. Regardless of their perception, the PHFP showed much concern about safe food, hence, further planning and implementation of food safety related programs, as well as better education about safe food can help to mitigate these issues in this community. A number of recommendations were provided to inform future food safety related programs and additional research that aims to reduce foodborne illnesses in this community.

description: We observed three AGN from the Parkes Half-Jansky Flat-spectrum Sample at near-infrared (NIR) wavelengths to search for micro-variability. In one source, the blue quasar PKS 2243-123, good evidence for NIR micro-variability was found. In the other two sources, PKS 2240-260 and PKS 2233-148, both BL Lacertae objects, no such evidence of variability was detected. We discuss the implications of these observations for the various mechanisms that have been proposed for micro-variability.

description: The optical properties of sub-wavelength arrays of atoms or other quantum emitters have attracted significant interest recently. For example, the strong constructive or destructive interference of emitted light enables arrays to function as nearly perfect mirrors, support topological edge states, and allow for exponentially better quantum memories. In these proposals, the assumed atomic structure was simple, consisting of a unique electronic ground state. Within linear optics, the system is then equivalent to a periodic array of classical dielectric particles, whose periodicity supports the emergence of guided modes. However, it has not been known whether such phenomena persist in the presence of hyperfine structure, as exhibited by most quantum emitters. Here, we show that waveguiding can arise from rich atomic entanglement as a quantum many-body effect, and elucidate the necessary conditions. Our work represents a significant step forward in understanding collective effects in arrays of atoms with realistic electronic structure.

description: Very recent data for the reaction gamma+d ->eta np, namely total cross sections, angular and momentum spectra, are analyzed within a model that includes contributions from the impulse approximation and next order corrections due to the np and eta-N interactions in the final state. Comparison between the calculations and the new data indicate sizable contributions from the np and eta-N final state interactions. Some systematic discrepancies between the calculations and the data are also found.
