description: We present an accurate characterization of the particle background behaviour on XMM-Newton based on the entire EPIC archive. This corresponds to the largest EPIC data set ever examined. Our results have been obtained thanks to the collaboration between the FP7 European program EXTraS and the ESA R&D ATHENA activity AREMBES. We used as a diagnostic an improved version of the diagnostic which compares the data collected in unexposed region of the detector with the region of the field of view in the EPIC-MOS. We will show that the in Field-of-View excess background is made up of two different components, one associated to flares produced by soft protons and the other one to a low-intensity background. Its origin needs to be further investigated.

description: The study performs large-eddy simulations of supersonic free jet flows using the Discontinuous Galerkin Spectral Element Method (DGSEM). The main objective of the present work is to assess the resolution requirements for adequate simulation of such flows with the DGSEM approach. The study looked at the influence of the mesh and the spatial discretization accuracy on the simulation results. The present analysis involves four simulations, incorporating three different numerical meshes and two different orders of spatial discretization accuracy. The numerical meshes are generated with distinct mesh topologies and refinement levels. Detailed descriptions of the grid generation and refinement procedures are presented. The study compares flow property profiles and power spectral densities of velocity components with experimental data. The results show a consistent improvement in the computed data as the simulation resolution increases. This investigation revealed a trade-off between mesh and polynomial refinement, striking a balance between computational cost and the accuracy of large-eddy simulation results for turbulent flow analyses.

Telling and hearing: learning from Macassan-Yoln̦u stories of connecting
Creators: name: Bilous, Rebecca Hâf
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis is about stories that connect Macassan people from the IndonesianIsland of Sulawesi, and YoIqu, Indigenous Australians from the north coast ofAustralia. These stories are important because they unsettle how Australiansunderstand their nation's histories and geographies, challenging manycommonly held assumptions. Yet many Australians, if they hear these stonesat all, often hear them filtered through a very limited number of academicdiscourses that rely on tangible objects and data, based on particularapproaches to research and seeing the world. This thesis starts by exploring the ways in which these discourses addressthese stories of connecting in museums and popular geographical journals. Itthen offers an alternative approach to telling, hearing and responding toMacassan-Yolrju stories by listening to Yolt]u elders in north-east ArnhemLand. The thesis offers not simply a framework for engaging with these Yolt]ustories of contact with and connection to Macassan people, nor simply acritique of a dominant discourse that reduces the complex histories andgeographies of connection to a rather singular 'Macassan contact', butcontributes to a more reflexive and pluralist perspective on the ways in whichknowledge is both created and shared. Finally, the thesis considers how thesediffering ways of telling and hearing Macassan-Yolqu stories might open up aspace for engaging with a multiplicity of knowledges, challenging learners andeducators to change the ways in which they tell, hear, teach and learn from allstories.

description: In this paper, we give a new criterion for the Cohen-Macaulayness of vertex splittable ideals, a family of monomial ideals recently introduced by Moradi and Khosh-Ahang. Our result relies on a Betti splitting of the ideal and provides an inductive way of checking the Cohen-Macaulay property. As a result, we obtain characterizations for Gorenstein, level and pseudo-Gorenstein vertex splittable ideals. Furthermore, we provide new and simpler combinatorial proofs of known Cohen-Macaulay criteria for several families of monomial ideals, such as (vector-spread) strongly stable ideals and (componentwise) polymatroidals. Finally, we characterize the family of bi-Cohen-Macaulay graphs by the novel criterion for the Cohen-Macaulayness of vertex splittable ideals.

description: We show that Rashba spin-orbit coupling at the interface between a superconductor and a ferromagnet should produce a spontaneous current in the atomic thickness region near the interface. This current is counter-balanced by the superconducting screening current flowing in the region of the width of the London penetration depth near the interface. Such current carrying state creates a magnetic field near the superconductor surface, generates a stray magnetic field outside the sample edges, changes the slope of the temperature dependence of the critical field $H_{c3}$ and may generate the spontaneous Abrikosov vortices near the interface.

Why pacaranas never say no: analysis of the unique occipitocervical configuration of †Tetrastylus intermedius Rovereto, 1914, and other dinomyids (Caviomorpha; Dinomyidae)

description: Dinomyidae is a South American caviomorph family that was a very diverse group starting in the Miocene, but is now represented by a single species, Dinomys branickii Peters, 1873. An exclusive feature of dinomyids, not recorded in other mammals, is the presence of accessory articular structures lateral to the occipital condyles, termed paracondyles. In a 1916 study of †Tetrastylus intermedius Rovereto, 1914, an extinct dinomyid from northwestern Argentina, Carlos Ameghino suggested that the paracondyles enhance the support of a large and heavy head. At present, this is the only proposal to explain the presence of these structures. In order to validate this hypothesis, we performed descriptive, metric osteological analyses, and muscular reconstructions of the occipital and cervical regions of †T. intermedius, D. branickii, and other dinomyids, in a comparative context of rodent diversity. We confirmed that, similar to some other living rodents, D. branickii possesses a relatively large head. Conversely, †T. intermedius possesses a size-proportionate head and has larger paracondyles than D. branickii. Our analyses suggested that fossil dinomyids would have performed more marked sagittal movements than D. branickii, and that paracondyles and the whole occipitocervical configuration of dinomyids are specialized for restriction of movements of the head and neck. We rejected the single previous hypothesis and proposed an alternative and novel one, in which paracondyles, and other occipitocervical traits present in dinomyids, as well as in erethizontids, could be related to restricted movements and linked to ecological convergences for stealthy and slow arboreal locomotion.

description: A detailed characterization of the particle induced background is fundamental for many of the scientific objectives of the Athena X-ray telescope, thus an adequate knowledge of the background that will be encountered by Athena is desirable. Current X-ray telescopes have shown that the intensity of the particle induced background can be highly variable. Different regions of the magnetosphere can have very different environmental conditions, which can, in principle, differently affect the particle induced background detected by the instruments. We present results concerning the influence of the magnetospheric environment on the background detected by EPIC instrument onboard XMM-Newton through the estimate of the variation of the in-Field-of-View background excess along the XMM-Newton orbit. An important contribution to the XMM background, which may affect the Athena background as well, comes from soft proton flares. Along with the flaring component a low-intensity component is also present. We find that both show modest variations in the different magnetozones and that the soft proton component shows a strong trend with the distance from Earth.

description: Superbolides, i.e. extremely bright meteors produced by entries of meter-sized bodies into terrestrial atmosphere, are rare events. We present here detailed analysis of a superbolide, which occurred over Romania on January 7, 2015. The trajectory, velocity, and orbit were determined using two all-sky photographs from a station of the European Fireball Network (EN) in Slovakia and five casual video records from Romania, which were carefully calibrated. Bolide light curve was measured by EN radiometers. We found that the entry speed was 27.76 $\pm$ 0.19 km/s, significantly lower than reported by US Government sensors. The orbit was asteroidal with low inclination and aphelion inside Jupiter's orbit. The atmospheric behavior was, however, not typical for an asteroidal body. The peak brightness of absolute magnitude of -21 was reached at a quite large height of 42.8 km and the brightness then decreased quickly. The bolide almost disappeared at a height of 38.7 km, leaving just a stationary luminous trail visible for several seconds. Only one small fragment continued until the height of 36 km. Brief meteorite searches were unsuccessful. The modeling of the light curve revealed that the body of initial mass of about 4500 kg remained almost intact until the dynamic pressure reached 0.9 MPa but it was then quickly disintegrated into many tiny fragments and dust under 1-3 MPa. A comparison was made with three other superbolides for which we have radiometric light curves: ordinary chondrite fall Košice, carbonaceous chondrite fall Maribo, and cometary Taurid bolide of October 31, 2015. The Romanian superbolide was not similar to any of these and represents probably a new type of material with intrinsic strength of about 1 MPa.

description: Here, we report the synthesis of photo- and thermochromic spiropyrans promoted by a highly efficient, biocompatible, and reusable choline hydroxide (ChOH) in greener solvent water. This procedure provides several advantages such as simple workup, mild reaction conditions, short reaction time, and high yields of the products. Furthermore, the ChOH could be reused at least five times without significantly losing its catalytic activity. The structures of the synthesized spiropyran derivatives were confirmed by several characterization methods such as 1H NMR, 13C NMR, and mass spectra.

description: We study the specialization of the type A nonsymmetric Macdonald polynomials at $t=0$ based on the combinatorial formula of Haglund, Haiman, and Loehr. We prove that this specialization expands nonnegatively into the fundamental slide polynomials, introduced by the author and Searles. Using this and weak dual equivalence, we prove combinatorially that this specialization is a positive graded sum of Demazure characters. We use stability results for fundamental slide polynomials to show that this specialization stabilizes and to show that the Demazure character coefficients give a refinement of the Kostka--Foulkes polynomials.

description: To further current methodology and understanding regarding heat transfer in motorsport tyres, RANS/URANS methodologies were created and compared to investigate natural and mixed convection phenomena in a simplified tyre geometry subject to a thermal gradient from rim surface to tyre crown. At a Rayleigh Number (Ra) of 5.02 ×106 natural convection phenomena were investigated and variation in outer cylinder Nusselt Number (Nu) was quantified. With rotational effects at a higher Rayleigh Number of 1.094×107, a weak correlation between Reynolds Number (Re) and outer cylinder Nu was found with 21% variation across the whole Re range (4.851 ×105 < Re < 1.698 × 106), with most variation occurring at lower Re. Further, a RANS and URANS methodology were compared for resolution of Natural Convection phenomena. Steady-State and Transient Implicit solvers were compared with minimal variation in results but the transient solver taking 0.709% longer per iteration and 51.06% longer to converge. The transient methodology showed promise however as they did not encounter similar stability issues as steady-state solutions at higher Ra.

description: The poorly studied variable star V390 Sco, previously classified as a Mira pulsator, was detected in a brightening event by the ESA Gaia satellite in September 2023. This work presents an analysis of available archival multifrequency photometric data of this target, along with our spectroscopic observations. Our findings lead to the conclusion that V390 Sco is a new symbiotic star identified by Gaia, currently undergoing a classical symbiotic outburst. Additionally, we uncovered three prior outbursts of this system through archival photometry. The outbursts recur approximately every 2330 - 2400 days, and we hypothesize the periastron passage in an eccentric orbit may trigger them, similarly to the case of BX Mon, DD Mic, or MWC 560. A detailed investigation into the nature of the donor star suggested that V390 Sco is an S-type symbiotic star, likely hosting a less evolved, semiregularly pulsating giant donor, but not a Mira variable.

Optical tactile sensor for slip detection of a grasped object
Creators: name: Ly, Kien
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Intelligent grasping is required by autonomous robots to lift objects with unknown weight. This requires the gripper robot to have enough grasping force so that the object does not slip out of the gripper, but not too much force, for otherwise the object may be damaged. The development of an optical tactile sensor can be an approach to intelligent grasping for a robotic gripper. Initial results collected showed that using an infrared sensor in a deforming material will provide slip detection for the gripper robot. Combining this tactile sensor with the gripper robot will create a feedback system that can detect slip and adjust gripping strength for intelligent grasping. The low cost and the small size of the tactile sensor offers a cost efficient and adaptable tactile sensor design for an autonomous small gripper robot used to pick and place packages. The aim of this thesis is to improve an existing design and incorporate elements from other successful tactile sensor designs. Various issues are present with the proposed design which are solved. The infrared sensor will be affected by ambient lighting which can be controlled by placing the sensor in a cavity which no external light sources can affect. There is also the issue of choosing a deformable material which is not too soft otherwise it will always deform or too stiff otherwise it will not deform when the object is slipping. The system must also have a fast response time to detect slip in under one second as well as when slippage occurs at 1mm or less. This may be solved by using a mouse sensor which has a high response time in microseconds and can detect changes in position under 1 mm.

description: This study aims to investigate the collective experiences of teachers who work with students who are twice exceptional in inclusive classrooms. Data were gathered through semi-structured interviews with six experienced teachers with at least five years of experience dealing with twice-exceptional learners as part of the study's qualitative research design. The results showed that the teachers encountered several difficulties and struggles while interacting with this demographic, including determining the learner's strengths and weaknesses, misconceptions about their job, lack of learning facilities, and handling their behavioral and emotional requirements. However, the teachers also mentioned feeling fulfillment and satisfaction after seeing their kids progress and achieve their goals. It also includes a sense of satisfaction with the salary and the incentives they receive. Moreover, the study highlighted the importance of teacher training and professional development in equipping educators with the necessary skills and knowledge to teach twice-exceptional learners effectively. The study concluded that addressing the challenges met by the teachers when working with this requires a collaborative effort between educators, parents, and policymakers to ensure that twice-exceptional learners receive the education they deserve.

DNA double strand breaks (DSBs) constitute a toxic class of DNA lesion and multiple cellular pathways exist to mediate their repair. Robust and titratable assays of cellular DSB repair (DSBR) are important to functionally interrogate the integrity and efficiency of these mechanisms in disease models as well as in response to genetic or pharmacological perturbations. Several variants of DSBR reporters are available, however these are often limited by throughput or restricted to specific cellular models. Here, we describe the generation and validation of a suite of extrachromosomal reporter assays that can efficiently measure the major DSBR pathways of homologous recombination (HR), classical nonhomologous end joining (cNHEJ), microhomology-mediated end joining (MMEJ) and single strand annealing (SSA). We demonstrate that these assays can be adapted to a high-throughput screening format and that they are sensitive to pharmacological modulation, thus providing mechanistic and quantitative insights into compound potency, selectivity, and on-target specificity. We propose that these reporter assays can serve as tools to dissect the interplay of DSBR pathway networks in cells and will have broad implications for studies of DSBR mechanisms in basic research and drug discovery.

description: The structural, magnetic, and electronic properties of NdFe$_{0.5}$Mn$_{0.5}$O$_3$ have been studied in detail using bulk magnetization, neutron/x-ray diffraction and first principles density functional theory calculations. The material crystallizes in the orthorhombic $Pbnm$ structure, where both Mn and Fe occupy the same crystallographic site ($4b$). Mn/Fe sublattice of the compound orders in to a G-type antiferromagnetic phase close to 250\,K where the magnetic structure belongs to $Γ_{1}$ irreducible representation with spins aligned along the crystallographic $b$ direction. This is unconventional in the sense that most of the orthoferrites and orthochromites order in the $Γ_{4}$ representation below the Néel temperature.This magnetic structure then undergoes a complete spin reorientation transition with temperature in the range 75\,K$\gtrsim$ T $\gtrsim$ 25\,K where the magnetic structure exists as a sum of two irreducible representations ($Γ_{1}$+$Γ_{2}$) as seen from neutron diffraction measurements. At 6\,K, the magnetic structure belongs entirely to $Γ_{2}$ representation with spins aligned antiferromagnetically along the crystallographic $c$ direction having a small ferromagnetic component ($F_x$). The unusual spin reorientation and correlation between magnetic ground state and electronic structure have been investigated using first principles calculations within GGA+U and GGA+U+SO formalisms.

description: In some situations, the interpretability of the machine learning models plays a role as important as the model accuracy. Interpretability comes from the need to trust the prediction model, verify some of its properties, or even enforce them to improve fairness. Many model-agnostic explanatory methods exists to provide explanations for black-box models. In the regression task, the practitioner can use white-boxes or gray-boxes models to achieve more interpretable results, which is the case of symbolic regression. When using an explanatory method, and since interpretability lacks a rigorous definition, there is a need to evaluate and compare the quality and different explainers. This paper proposes a benchmark scheme to evaluate explanatory methods to explain regression models, mainly symbolic regression models. Experiments were performed using 100 physics equations with different interpretable and non-interpretable regression methods and popular explanation methods, evaluating the performance of the explainers performance with several explanation measures. In addition, we further analyzed four benchmarks from the GP community. The results have shown that Symbolic Regression models can be an interesting alternative to white-box and black-box models that is capable of returning accurate models with appropriate explanations. Regarding the explainers, we observed that Partial Effects and SHAP were the most robust explanation models, with Integrated Gradients being unstable only with tree-based models. This benchmark is publicly available for further experiments.

description: As a principal compound of cinnamon essential oil, cinnamaldehyde has been used as a marker for the quality control of cinnamon and its essential oil. During the HPLC analysis, a reaction product was observed in methanol solution of cinnamaldehyde reference standard. This product was isolated and identified to be cinnamaldehyde dimethyl acetal based on the spectroscopic analysis. Although dimethylacetalization of cinnamaldehyde in MeOH has been recorded in many literatures, this is the first report about this reaction in normal analysis procedure. Further studies suggested that this reaction could be affected by many parameters, including cinnamaldehyde concentration, storage temperature, and light illumination. Those results suggested the stock solution of cinnamaldehyde reference standard should not be prepared with methanol, and the extraction procedure by heating the sample with methanol might accelerate the acetalization of cinnamaldehyde. The use of methanol during the analysis of cinnamaldehyde should be carefully considered.

description: Online network crawling tasks require a lot of efforts for the researchers to collect the data. One of them is identification of important nodes, which has many applications starting from viral marketing to the prevention of disease spread. Various crawling algorithms has been suggested but their efficiency is not studied well. In this paper we compared six known crawlers on the task of collecting the fraction of the most influential nodes of graph.
 We analyzed crawlers behavior for four measures of node influence: node degree, k-coreness, betweenness centrality, and eccentricity. The experiments confirmed that greedy methods perform the best in many settings, but the cases exist when they are very inefficient.

description: Tidal encounters are believed to be one of the key drivers of galactic spiral structure in the Universe. Such spirals are expected to produce different morphological and kinematic features compared to density wave and dynamic spiral arms. In this work we present high resolution simulations of a tidal encounter of a small mass companion with a disc galaxy. Included are the effects of gas cooling and heating, star formation and stellar feedback. The structure of the perturbed disc differs greatly from the isolated galaxy, showing clear spiral features that act as sites of new star formation, and displaying interarm spurs. The two arms of the galaxy, the bridge and tail, appear to behave differently; with different star formation histories and structure. Specific attention is focused on offsets between gas and stellar spiral features which can be directly compared to observations. We find some offsets do exist between different media, with gaseous arms appearing mostly on the convex side of the stellar arms, though the exact locations appear highly time dependent. These results further highlight the differences between tidal spirals and other theories of arm structure.

Thermal maturities and inferred palaeoenvironments of hydrocarbons from the southern Sydney Basin
Creators: name: Campbell, Bronwyn
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: The Shoalhaven Group in the southern Sydney Basin contains an extensive sedimentary record of the Permian period. Regional thermal maturity and palaeoenvironments have been interpreted using hydrocarbons primarily from drillcore DM Callala DDH1, Jervis Bay. Palaeoenvironmental interpretation is largely inhibited by thermal maturity in the Shoalhaven Group, with calculated vitrinite reectance values associated with the wet gas condensate window. These high thermal maturities are attributed to the large volume of overburden deposited above the Shoalhaven Group during the Mesozoic. Wildfire-associated polycyclic aromatic hydrocarbons have been used in place of more common biomarkers, and indicate relative changes from cooler climates in the early Permian to warmer, more temperate climates in the mid Permian and probable cool, dry climate in the mid to late Permian. Relative proportions of dibenzothiophene to fluorene are recommended as indicators of source input for high thermal maturity organic matter, as data preferentially clustered by formation and expected source input.

description: We introduce the French Street Name Signs (FSNS) Dataset consisting of more than a million images of street name signs cropped from Google Street View images of France. Each image contains several views of the same street name sign. Every image has normalized, title case folded ground-truth text as it would appear on a map. We believe that the FSNS dataset is large and complex enough to train a deep network of significant complexity to solve the street name extraction problem "end-to-end" or to explore the design trade-offs between a single complex engineered network and multiple sub-networks designed and trained to solve sub-problems. We present such an "end-to-end" network/graph for Tensor Flow and its results on the FSNS dataset.
