description: Recently theoretical works predict that some semiconductors (e.g. ZnO) doped with magnetic ions are diluted magnetic semiconductors (DMS). In DMS magnetic ions substitute cation sites of the host semiconductor and are coupled by free carriers resulting in ferromagnetism. One of the main obstacles in creating DMS materials is the formation of secondary phases because of the solid-solubility limit of magnetic ions in semiconductor host. In our study transition metal ions were implanted into ZnO single crystals with the peak concentrations of 0.5-10 at.%. We established a correlation between structural and magnetic properties. By synchrotron radiation X-ray diffraction (XRD) secondary phases (Fe, Ni, Co and ferrite nanocrystals) were observed and have been identified as the source for ferromagnetism. Due to their different crystallographic orientation with respect to the host crystal these nanocrystals in some cases are very difficult to be detected by a simple Bragg-Brentano scan. This results in the pitfall of using XRD to exclude secondary phase formation in DMS materials. For comparison, the solubility of Co diluted in ZnO films ranges between 10 and 40 at.% using different growth conditions pulsed laser deposition. Such diluted, Co-doped ZnO films show paramagnetic behaviour. However, only the magnetoresistance of Co-doped ZnO films reveals possible s-d exchange interaction as compared to Co-implanted ZnO single crystals.

description: Transmit signal and bandwidth optimization is considered in multiple-antenna relay channels. Assuming all terminals have channel state information, the cut-set capacity upper bound and decode-and-forward rate under full-duplex relaying are evaluated by formulating them as convex optimization problems. For half-duplex relays, bandwidth allocation and transmit signals are optimized jointly. Moreover, achievable rates based on the compress-and-forward transmission strategy are presented using rate-distortion and Wyner-Ziv compression schemes. It is observed that when the relay is close to the source, decode-and-forward is almost optimal, whereas compress-and-forward achieves good performance when the relay is close to the destination.

description: With millions of extant species, ecdysozoans (Scalidophora, Nematoida and Panarthropoda) constitute a major portion of present-day biodiversity. All ecdysozoans secrete an exoskeletal cuticle which must be moulted periodically and replaced by a larger one. Although moulting (ecdysis) has been recognized in early Palaeozoic panarthropods such as trilobites and basal groups such as anomalocaridids and lobopodians, the fossil record lacks clear evidence of ecdysis in early scalidophorans, largely because of difficulties in recognizing true exuviae. Here, we describe two types of exuviae in microscopic scalidophoran worms from the lowermost Cambrian Kuanchuanpu Formation (ca 535 Ma) of China and reconstruct their moulting process. These basal scalidophorans moulted in a manner similar to that of extant priapulid worms, extricating themselves smoothly from their old tubular cuticle or turning their exuviae inside out like the finger of a glove. This is the oldest record of moulting in ecdysozoans. We also discuss the origin of ecdysis in the light of recent molecular analyses and the significance of moulting in the early evolution of animals.

description: LiDAR-camera systems have become increasingly popular in robotics recently. A critical and initial step in integrating the LiDAR and camera data is the calibration of the LiDAR-camera system. Most existing calibration methods rely on auxiliary target objects, which often involve complex manual operations, whereas targetless methods have yet to achieve practical effectiveness. Recognizing that 2D Gaussian Splatting (2DGS) can reconstruct geometric information from camera image sequences, we propose a calibration method that estimates LiDAR-camera extrinsic parameters using geometric constraints. The proposed method begins by reconstructing colorless 2DGS using LiDAR point clouds. Subsequently, we update the colors of the Gaussian splats by minimizing the photometric loss. The extrinsic parameters are optimized during this process. Additionally, we address the limitations of the photometric loss by incorporating the reprojection and triangulation losses, thereby enhancing the calibration robustness and accuracy.

Publisher: name: University Of Tasmania
Year: 2023

description: In this thesis, I examined the quality and effectiveness of forest governance, particularly in relation to tourism, in a protected area, the Mudumalai forest in Tamilnadu state, India. This forest has been chosen as a case study because of the growing popularity of tourism in the area, as well as the challenges of developing effective relationships between forest governors and local communities. This thesis aimed to assess the quality of tourism governance in Mudumalai forest in terms of legitimacy, accountability, transparency, inclusiveness and fairness; and effectiveness in terms of supervision and monitoring. The overall quality and effectiveness of the tourism governance in Mudumalai forest is found to be good, based on evidence gained from key informant interviews, field visits and from the literature. This thesis has made recommendations for improving tourism governance in Mudumalai forest, including: ‚Äö a need to shift from a purely conferred legitimacy status to a combination of conferred and earned legitimacy; ‚Äö addressing local community fears and concerns by implementing regular and improved community engagement programs; ‚Äö using a transparent and inclusive process to develop a management plan for the forest, and effectively communicating the plan to stakeholders; ‚Äö improving the downward accountability of governance from local officials to the local community; ‚Äö treating inclusiveness and fairness as principles of good governance, rather than treating them as a means to control or change the forest dependent lifestyle of the local community; and ‚Äö modernising the supervision and monitoring techniques used in Mudumalai.

description: Pathogenesis-related (PR) protein-5, is involved in host defense system against both biotic and abiotic stresses as well as the regulation of physiological processes in numerous plant species. Our earlier studies have reported the isolation of a full-length TaLr19TLP1 gene (516 bp, GenBank accession No. KJ764822) from wheat infected by leaf rust. Quantitative real-time polymerase chain reaction analyses revealed that TaLr19TLP1 transcript was significantly induced and upregulated during incompatible interaction, while a relatively low level of the transcript was detected during compatible interaction. In the current study, we demonstrate that the accumulation of TaLr19TLP1 transcript is significantly different in tested wheat organs. TaLr19TLP1 was induced by salicylic acid (SA), methyl jasmonic (MeJA), ethephon (ETH) and abscisic acid (ABA). The transcripts of TaLr19TLP1 accumulated at higher levels following pretreatment with SA, MeJA and ABA prior to infection with P. triticina. A slight induction was observed in ETH pretreated seedlings compared with the treatment without inoculation. In addition, TaLr19TLP1 was found to be predominately localized to extracellular spaces of onion epidermal cell. Knocking down the expression of TaLr19TLP1 through virus-induced gene silencing reduced wheat resistance against leaf rust pathogen. These results suggested that TaLr19TLP1 mediated disease resistance in wheat exposed to leaf rust pathogen.

description: Using computer simulations, we studied the diffusion and structural relaxation in equilibrium smectic liquid crystal bulk phases of parallel hard spherocylinders. These systems exhibit a non-Gaussian layer-to-layer diffusion due to the presence of periodic barriers and transient cages, and show remarkable similarities with the behavior of out-of-equilibrium supercooled liquids. We detect a very slow inter-layer relaxation dynamics over the whole density range of the stable smectic phase which spans a time interval of four time decades. The intrinsic nature of the layered structure yields a hopping-type diffusion which becomes more heterogeneous for higher packing fractions. In contrast, the in-layer dynamics is typical of a dense fluid with a relatively fast decay. Our results on the dynamic behavior agree well with that observed in systems of freely rotating hard rods, but differ quantitavely, as the height of the periodic barriers reduces to zero at the nematic-smectic transition for aligned rods, while it remains finite for freely rotating rods.

description: We propose a new framework unifying cold dark matter (CDM) and Modified Newtonian Dynamics (MOND) to solve their respective problems on galactic scales and large scale structure formation. In our framework the dark matter clusters on large scales but not on galactic scales. This environment dependence of the dark matter behaviors is controlled by a vector field, which also produces the MOND effects in galaxies. We find that in this framework only a single mass scale needs to be introduced to produce the phenomena of CDM, MOND and also dark energy.

description: The aim of the paper is to present the ways in which entrepreneurs in the food service industry react to the pandemic, evaluate the efficiency of their actions, and suggest the most effective solutions to the market disruptions caused by the COVID-19 pandemic in Poland. The study used the descriptive analysis method, Pearson correlation survey method, and logical inference. Based on literature analysis and observations, questions were formulated for a survey for Polish entrepreneurs in the food service industry. The sample of surveyed entrepreneurs was selected by systematic random sampling from a group of entrepreneurs who promoted their enterprises through social media channels between 2019 and 2020. Among the surveyed enterprises, there is a positive correlation with undertaking activities concerning online brand image development and satisfaction with profits. Introducing their own deliveries during the pandemic, food service enterprises showed a negative correlation with profit growth. Enterprises that chose not to run their own supply networks, but consistently develop their brand image online, showed a positive correlation with increased satisfaction with earned profits. Analyzing the results of the study one can find some correlations. Enterprises which do not run their own supply networks, but instead consistently work on their brand image in the network and cooperate with enterprises operating in accordance with the sharing economy model, are doing well in times of the crisis. Enterprises that conduct their activities in accordance with the described assumptions showed a strong positive correlation with increased satisfaction with their net income.

description: Recent excavations at the Olduvai Gorge in Tanzania, Africa have revealed new information about some of the earliest hominins, probably Homo habilis, from 2 million years ago. For the purposes of this article, the main point is that these early humans walked 12 km or 7.5 miles to gather specific stones that they used for making Oldowan stone tools and for putting together a toolkit. And these specific stones made up the majority of stones found. They did this for several hundred thousand years. I argue that to do this, they probably had containers or early baskets to help them carry a large collection of stones back to their settlements, since walking that far would have been counterproductive if they only gathered a few stones. Next in this article, I show how very simple carriers could have been from natural plant materials, carriers that might have been like some of the earliest baskets.
Wild fire hazard in the environs of Hobart

Year: 2023

description: This work investigates and makes recommendation on the wild fire hazard that exists in the environs of Hobart. The underlying theme is that of protecting life and property while still giving due cognizance to other environmental and social values that exist in the area. The factors that influence fire behaviour are discussed and then applied to the Hobart area thereby qualifying it from a general fire danger perspective and showing that variations in fire danger occur over the area commensurate with variations in topography, vegetation and precipitation. The ways in which a bush fire conflagration may threaten or destroy life and property are detailed and from this perspective protection and survival techniques are proposed. The present programme aimed at ameliorating the wild fire hazard is briefly outlined; the main aspects of this programme involve the control of fires during fire danger periods, and reduction of fuel loadings, the suppression of outbreaks and public education. The hazard reduction burning aspect of the current fire management prcgramme is discussed with respect to its rationale and environmental implications, including the possible effects on vegetation, soil and wildlife. An attempt is made to rationalize the wild fire management programme in the area in such a way that greater emphasis may be given to other environmental and social values that exist within the area. This rationalization or reorientation involves the de-emphasising of the part currently played by broad area hazard reduction burning combined with a greater emphasis on localized protection and effective prevention and suppression of fire outbreaks.

description: We present mid-infrared Period-Luminosity relations for Cepheids in the Local Group galaxy IC1613. Using archival IRAC imaging data from Spitzer we were able to measure single-epoch magnitudes for five, 7 to 50-day, Cepheids at 3.6 and 4.5 microns. When fit to the calibrating relations, measured for the Large Magellanic Cloud Cepheids, the data give apparent distance moduli of 24.29 +/- 0.07 and 24.28 +/- 0.07 at 3.6 and 4.5 microns, respectively. A multi-wavelength fit to previously published BVRIJHK apparent moduli and the two IRAC moduli gives a true distance modulus of 24.27 +/- 0.02 mag with E(B-V) = 0.08 mag, and a corresponding metric distance of 715 kpc. Given that these results are based on single-phase observations derived from exposures having total integration times of only 1,000 sec/pixel we suggest that Cepheids out to about 2 Mpc are accessible to Spitzer with modest integration times during its warm mission. We identify the main limiting factor to this method to be crowding/contamination induced by the ubiquitous population of infrared-bright AGB stars.

description: As planetary nebulae (PNe) evolve, they develop slow and strong dust-driven stellar winds, making the joint study of dust and gas essential for understanding their nature. As a pilot investigation, we selected PN K 3-54 as our target, the only known PN in the Milky Way to exhibit infrared emission from both graphene (C$_{24}$) and fullerene (C$_{60}$). The gas is traced via molecular line emissions from $^{12}$CO, $^{13}$CO, and C$^{18}$O ($J = 1 \rightarrow 0$), observed using the 13.7 m telescope of the Purple Mountain Observatory. We investigate the dynamics of this PN and identify a bipolar outflow. Preliminary results suggest that the large dynamical timescale of the outflow and the weak shock environment may account for the simultaneous survival of C$_{24}$ and C$_{60}$ within and around PN K 3-54.

description: Nurse rostering is a complex scheduling problem that affects hospital personnel on a daily basis all over the world. This paper presents a new component-based approach with evolutionary eliminations, for a nurse scheduling problem arising at a major UK hospital. The main idea behind this technique is to decompose a schedule into its components (i.e. the allocated shift pattern of each nurse), and then to implement two evolutionary elimination strategies mimicking natural selection and natural mutation process on these components respectively to iteratively deliver better schedules. The worthiness of all components in the schedule has to be continuously demonstrated in order for them to remain there. This demonstration employs an evaluation function which evaluates how well each component contributes towards the final objective. Two elimination steps are then applied: the first elimination eliminates a number of components that are deemed not worthy to stay in the current schedule; the second elimination may also throw out, with a low level of probability, some worthy components. The eliminated components are replenished with new ones using a set of constructive heuristics using local optimality criteria. Computational results using 52 data instances demonstrate the applicability of the proposed approach in solving real-world problems.

description: We have investigated the outbursts of IGR J17473-2721. We analyzed all available observations carried out by RXTE on IGR J17473-2721 during its later outburst and as well all the available SWIFT/BAT data. The flux of the latter outburst rose in ~ one month and then kept roughly constant for the following ~ two months. During this time period, the source was in a low/hard state. The source moved to a high/soft state within the following three days, accompanied by the occurrence of an additional outburst at soft X-rays and the end of the preceding outburst in hard X-rays. During the decay of this soft outburst, the source went back to a low/hard state within 6 days, with a luminosity 4 times lower than the first transition. This shows a full cycle of the hysteresis in transition between the hard and the soft states. The fact that the flux remained roughly constant for ~ two months at times prior to the spectral transition to a high/soft state might be regarded as the result of balancing the evaporation of the inner disk and the inward accretion flow, in a model in which the state transition is determined by the mass flow rate. Such a balance might be broken via an additional mass flow accreting onto the inner disk, which lightens the extra soft outburst and causes the state transition. However, the possibility of an origin of the emission from the jet during this time period cannot be excluded. The spectral analysis suggests an inclined XRB system for IGR J17473-2721. Such a long-lived preceding low/hard state makes IGR J17473-2721 resemble the behavior of outbursts seen in black hole X-ray binaries like GX 339-4.

description: We study the Casimir effect in the presence of an extra dimension compactified on a circle of radius R ($M^4\times S^1$ spacetime). Our starting point is the Kaluza Klein decomposition of the 5D Maxwell action into a massless sector containing the 4D Maxwell action and an extra massless scalar field and a Proca sector containing 4D gauge fields with masses $m_n=n/R$ where $n$ is a positive integer. An important point is that, in the presence of perfectly conducting parallel plates, the three degrees of freedom do not yield three discrete (non-penetrating) modes but two discrete modes and one continuum (penetrating) mode. The massless sector reproduces Casimir's original result and the Proca sector yields the corrections. The contribution from the Proca continuum mode is obtained within the framework of Lifshitz theory for plane parallel dielectrics whereas the discrete modes are calculated via 5D formulas for the piston geometry. An interesting manifestation of the extra compact dimension is that the Casimir force between perfectly conducting plates depends on the thicknesses of the slabs.

description: Graphene is the extreme material for molecular sensory and hydrogen storage applications because of its two-dimensional geometry and unique structure-property relationship. In this Letter, hydrogenation of graphene is discussed in the extent of intercoupling between mechanical deformation and electronic configuration. Our first principles calculation reveals that the atomic structures, binding energies, mechanical and electronic properties of graphene are significantly modified by the hydrogenation and applied strain. Under an in-plane strain of 10 %, the binding energies of hydrogen on graphene can be improved by 53.89 % and 23.56 % in the symmetric and anti-symmetric phase respectively. Furthermore the instability of symmetrically bound hydrogen atoms under compression suggests a reversible storage approach of hydrogen. In the anti-symmetric phase, the binding of hydrogen breaks the sp2 characteristic of graphene, which can be partly recovered at tensile strain. A charge density based analysis unveils the underline mechanisms. The results reported here offer a way not only to tune the binding of hydrogen on graphene in a controllable and reversible manner, but also to engineer the properties of graphene through a synergistic control through mechanical loads and hydrogen doping.
A marketing model of transportation demand at industrial sites
Creators: name: Dawson, Ian N.
Publisher: name: University of British Columbia
Year: 2010

description: This study analyses the factors which influence the volume of truck movement from urban manufacturing sites. The significance of these factors is tested by means of a case study of forty-three wood products plants in Vancouver, British Columbia. Some of the dangers of applying the assumptions of urban passenger travel "analysis to urban goods movement studies are discussed, with emphasis on the problems of aggregation and forecasting. A review of urban goods movement studies to date shows that previous research does not incorporate explanations of the causal mechanism behind variations in truck transport demand, but rather relies on simple within-site variables such as employment size to estimate the volume of trip-making. A marketing model is proposed. It takes the form of least-squares multiple regression equations which add marketing variables to the basic plant-size model. The development of the theory behind the marketing model discusses the expected influence of the manufacturer's physical distribution channel on his trip generation rate. Characteristics of the channel which are expected to be significant are the behaviour of customers for the product with respect to shipment size, transport supply, and their own function in the distribution channel. The effects of marketing variables are tested using data gathered by a personal survey of truck movements over a period of one month from wood products manufacturers. A significant improvement in the explanatory power of the marketing model over the plant-size model was revealed when the proportion of the manufacturer's market which is retail-oriented in taken into account. The same survey data was used to estimate retailers1 trip attraction rates. Size of their supply-market and truck capacity were found to be significant. Lastly, the future conditions which may limit applications of the model. are..discussed.

description: Obstructive sleep apnea (OSA) and hypertension are interrelated diseases linked to gut dysbiosis. This study aimed to investigate the effect of OSA on the gut microbiome in the context of hypertension and vice versa. Of 211 consecutively screened patients, 52 completed polysomnography study, medical history questionnaires, and fecal sample collection. 16S rRNA gene sequencing was performed on fecal samples, and diversity, richness, and microbial taxa were analyzed using bioinformatics. Alpha diversity showed slightly decreased diversity in OSA and hypertension groups without significant difference, and the hypoxia burden index (HBI) showed a weak positive correlation with Chao1 index (r = 0.342, p < 0.05) in OSA patients. Firmicutes-to-Bacteroidetes ratio was higher in patients with than without OSA. In hypertensive patients, those with OSA had higher Ruminococcus_1, Lachnoclostridium, Lachnospira, [Ruminococcus]_torques_group, and unidentified Lachnospiraceae levels than those without OSA. Conversely, in OSA patients, hypertensive patients had lower Faecalibacterium and Lachnospiraceae_NK4A136_group levels. The present study suggests a possible compensatory mechanism for gut microbiome changes in sleep apnea pathophysiology. The positive correlation between HBI and alpha diversity, and increase in certain genera of Ruminococcaceae and Lachnospiraceae in OSA patients may represent an adaptive response to hypoxia.

description: Bing-Whitehead Cantor sets were introduced by DeGryse and Osborne in dimension three and greater to produce examples of Cantor sets that were non standard (wild), but still had simply connected complement. In contrast to an earlier example of Kirkor, the construction techniques could be generalized to dimensions bigger than three. These Cantor sets in $S^{3}$ are constructed by using Bing or Whitehead links as stages in defining sequences. Ancel and Starbird, and separately Wright characterized the number of Bing links needed in such constructions so as to produce Cantor sets. However it was unknown whether varying the number of Bing and Whitehead links in the construction would produce non equivalent Cantor sets. Using a generalization of geometric index, and a careful analysis of three dimensional intersection patterns, we prove that Bing-Whitehead Cantor sets are equivalently embedded in $S^3$ if and only if their defining sequences differ by some finite number of Whitehead constructions. As a consequence, there are uncountably many non equivalent such Cantor sets in $S^{3}$ constructed with genus one tori and with simply connected complement.

description: We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model . Extending previous studies by inclusion of very high-mass resonances (m>2 GeV), and the up-to-now neglected scalar $σ$ meson leads to an improved description of the data. In particular, the hitherto poorly reproduced energy dependence of the K+/pi+ ratio at SPS energies ("the horn") is now well described through the connection to the hadronic mass spectrum and, implicitly, Hagedorn's limiting temperature.

Assessing early language development in Tasmanian children using the Australian English developmental vocabulary inventory (OZI)
Creators: name: Payne, DJF
Publisher: name: University Of Tasmania
Year: 2023

description: The ability to communicate is one of the most important skills a person can acquire, and therefore much research is devoted to language development. As language learning occurs in predictable stages, assessment tools aimed at examining these stages can be used to chart normal development. Research indicates that due to the nature of children's early attention skills, the results of some language assessment methods such as laboratory sessions can be compromised by external factors. These problems have sometimes been addressed by utilising parental reports, which have been proven to be valid and reliable sources of information. The MacArthur-Bates Communicative Developmental Inventory (CDI; Fenson et al., 1993) is a commonly used parental report that has been translated into a number of different languages as well as adapted for use with a number of other English-speaking populations. Because the language spoken in different populations vary according to cultural and historical influences, research into any future English adaptations is necessary in order to ensure that these adaptations are representative of the language and mirror the original CDI before they are published. Past research has utilised a number of assessment methods to validate wordlists. These include structured, standardised tests, as well as language samples obtained from laboratory sessions or diaries kept over a specific time. Examination of the interaction of variables such as maternal interaction, gender and birth-order with language development have also been used to examine whether a proposed adaptation displays similar results to those of studies using the CDI or other previously researched adaptations of it.

description: We reanalyze the WA98 single photon data at CERN SPS by incorporating several recent developments in the study of prompt and thermal photon production from relativistic heavy ion collisions. Isospin and shadowing corrected NLO pQCD, along with an optimized scale for factorization, fragmentation and renormalization are considered for prompt photon production. Photons from thermal medium are estimated by considering a boost invariant azimuthally anisotropic hydrodynamic expansion of the plasma along with a well tested equation of state and initial conditions. A quantitative explanation of the data is obtained by combining $κ\times$ prompt with thermal photons, where $κ$ is an overall scaling factor. We show that, elliptic flow of thermal photons can play a crucial role to distinguish between the `with' and `without' phase transition scenarios at SPS energy.

Shampoo mythology : the object, its meaning, its influences
Creators: name: Phillips, Anna
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis begins by examining the proposition that advertising appropriates symbolic, historical, and religious mythologies related to hair (head-hair being just one of our material culture definitions of the feminine) and then re-invests this signification and iconography into the shampoo bottle and its contents. The investigation considers the symbolic origins and relationships between hair, plastic and shampoo. Within the design and construction of the shampoo bottle's form- opalescent coated and soft feminised designs; its contents- thick, wholesome and creamy liquids; and its written text- didactic instructions and soothing reassurances, are unspoken messages designed not only to reinforce attitudes about hygiene and acceptable cleanliness levels but equally to act as signifiers related to identity, social position and confinement. The art objects incorporate familiar discarded plastic, such as early domestic Tupperware, and more recently plastic shampoo and conditioner bottles. Consumption of these objects is based upon the societal beliefs and myth with which they are imbued.1 Pastel-shaded Tupperware exemplifies feelings about the nuclear Anglo-Saxon family - movable, stackable and disposable. adherening to the values of consumption and modernity. There is a celebratory aspect to these mass-produced consumer items, something which Roland Barthes identified when he wrote of the magical properties of plastic: 'Plastic can be jewels as well as buckets.'2 The thesis explores, this 'misunderstood' medium. Plastic is investigated as a 'wonder' medium - transformed from its utilitarian beginnings and status. I have created works of a celebratory nature which examine its lyrical mythical potential as well as its utilitarian function. The sculptural works explore how plastic and hair have common concerns with artifice and appearance. Shampoo bottle text makes constant reference to the word 'natural'. Plastic is a polymer that established its identity as an imitator of the 'natural'. I have identified five 'types' of shampoo and conditioner bottles, aimed at stereo-typical representations of women and their defined environments. I see the plastic shampoo bottle as an object of desire. 'Shampoo Mythology' constantly refers to the 'Ultra Body'. An unending quest for the Ultra Body in our material culture has materialised because of the insistence of idealised visions of women, resulting in ceaseless dissection and fragmentation of the body from the self. 'Shampoo Mythology' is a deliberate construction of the mystique and spectacle of an object, the plastic shampoo bottle; a mythology which far surpasses the consequences and limitations of the object's intended function as a hair cleaner.
