description: Human vision seems so fast and effortless that we often don’t consider the processes that take place before we have the perceptual experience of “seeing”. However, by the time a stimulus first emerges into consciousness it has already been coded at various stages within the visual system. Recent evidence from patients with visual extinction has revealed that the active maintenance of an item in working memory facilitated enhanced awareness of targets that matched a previously viewed memory cue (Soto & Humphreys, 2006). Here, we asked whether the contents of working memory could facilitate efficient visual perception in normal subjects by triggering top-down signals that bias the visual system in favour of a preactivated object representation. Specifically, we hypothesised that target stimuli that matched a previously presented memory cue would be less susceptible to visual masking. In Experiments 1 and 2, we used transcranial magnetic stimulation (TMS) to the occipital pole as a method to degrade visual perception. However, we were unable to adequately mask targets and we instead provide a detailed discussion of the difficulties in localising area V1 using external anatomical landmarks. In Experiment 3, we used object substitution masking (OSM) to reduce awareness of target stimuli. In a typical OSM paradigm, visual masking occurs when a four-dot mask persists on the screen after target offset, whereas target detection is unimpaired by the simultaneous offset of the target and mask (Enns & Di Lollo, 1997). As predicted, we observed a significant main effect of Mask Offset. Detection sensitivity was higher on simultaneous-offset trials, relative to delayed-offset trials. In contrast, the interaction between Memory Match and Mask Offset was not significant. To overcome the limitations of inferential statistics in interpreting null findings, we implemented Bayesian statistics and obtained substantial evidence in favour of the null hypothesis. We conclude that merely holding something in working memory is not sufficient to enhance awareness of degraded visual objects.

description: Wireless access technologies have been extensively developed aiming to give users the ability to connect to their expected networks anytime, anywhere. This leads to an increment of the number of wireless interfaces integrated into a single mobile device, hence, it allows the device to be able to connect to multiple access networks. However, in some specific cases such as natural disasters, having an uncorrupted and timely information exchanging means is critical for affected victims to survive or to connect to the outside world. This is because the essential network infrastructures in these cases could be destroyed causing a large number of systems to stop working. In that cases, the victims need a heterogeneous communications network in which they can communicate, without a doubt, by using different wireless access technologies, i.e., Bluetooth or Wi-Fi. The network must also be able to smoothly change the access technologies, or called a vertical handover, to ensure QoS for ongoing applications. In addition, the network must have a mechanism to save energy. For hese reasons, an SDN approach, which has been proposed in a previous work, is considered. The performance of the system has been validated by a set of experiments in a real testbed. The obtained results show that the proposed vertical handover can save at least 24.42 per cent of the energy consumed by the wireless communication. The handover delay with different UDP traffic is less than 150ms. Moreover, the network allows a device using Bluetooth to talk with another one using Wi-Fi over a heterogeneous connection where the end-to-end jitter is mainly below 20ms and the packet loss rate is as small as 0.2 per cent.

description: Chanting is an ancient practice recognised in many cultures and traditions all over the world. It is typically used as a meditation practice for healing and psychological growth. The goal of the current investigation was to determine whether 12 minutes of vocal and silent group chanting of the sound 'Om' would result in reduced physiological and psychological stress and increased feelings of social connection. It was hypothesised that both vocal and silent forms of chanting would decrease stress and increase feelings of social connection, however, it was predicted that the effects of vocal chanting should be more robust. Psychology students from Macquarie University (M = 21.79, SD = 7.17) were randomly allocated to one of two conditions: vocal or silent chanting. Prior and post chanting, participants completed the State Trait Anxiety Inventory, Adapted Self-Report Altruism Scale (including an additional 6 questions on cross-cultural altruism) and provided a saliva sample to assess cortisol levels. Following chanting, participants completed a manipulation check and provided a written description of their experiences of the chanting. Following both vocal and silent chanting, self-reported stress and cortisol levels significantly decreased. The reduction in cortisol was similar for vocal and silent chanting, but self-reported stress decreased significantly more following vocal chanting than silent chanting. As predicted, altruism increased following both vocal and silent chanting. Interestingly, however, there was no evidence that this benefit extended experiences of cross-cultural altruism. The findings are discussed in view of current theory and evidence on the physiological and psychological effects of chanting, singing and meditation.

description: Removing the aberrations introduced by the Point Spread Function (PSF) is a fundamental aspect of astronomical image processing. The presence of noise in observed images makes deconvolution a nontrivial task that necessitates the use of regularisation. This task is particularly difficult when the PSF varies spatially as is the case for the Euclid telescope. New surveys will provide images containing thousand of galaxies and the deconvolution regularisation problem can be considered from a completely new perspective. In fact, one can assume that galaxies belong to a low-rank dimensional space. This work introduces the use of the low-rank matrix approximation as a regularisation prior for galaxy image deconvolution and compares its performance with a standard sparse regularisation technique. This new approach leads to a natural way to handle a space variant PSF. Deconvolution is performed using a Python code that implements a primal-dual splitting algorithm. The data set considered is a sample of 10 000 space-based galaxy images convolved with a known spatially varying Euclid-like PSF and including various levels of Gaussian additive noise. Performance is assessed by examining the deconvolved galaxy image pixels and shapes. The results demonstrate that for small samples of galaxies sparsity performs better in terms of pixel and shape recovery, while for larger samples of galaxies it is possible to obtain more accurate estimates of the galaxy shapes using the low-rank approximation.

description: Atia of the Julii and Servilia of the Junii reflect a number of stereotypically ‘feminine’ gendered characteristics as they have been depicted in both ancient and modern history. The HBO/BBC television series Rome relies upon historically gendered traditions of ‘a woman scorned’ and the ‘sexually corrupt and manipulative’ woman in Atia and Servilia’s depictions over the course of the series.This thesis aims to answer the question of how Atia and Servilia represent a blending of ancient and modern interpretations, and further elucidate how women of antiquity are extrapolated from their ancient characterisations and translated into a modern cinematic context.

description: Regarding the Veneziano ghost of QCD and its generalized form, we consider a Friedmann-Robertson-Walker (FRW) universe filled by a pressureless matter and a dark energy component interacting with each other through a mutual sign-changeable interaction of positive coupling constant. Our study shows that, at the late time, for the deceleration parameter we have $q\rightarrow-1$, while the equation of state parameter of the interacting ghost dark energy (GDE) does not cross the phantom line, namely $ω_D\geq-1$. We also extend our study to the generalized ghost dark energy (GGDE) model and show that, at late time, the equation of state parameter of the interacting GGDE also respects the phantom line in both flat and non-flat universes. Moreover, we find out that, unlike the non-flat universe, we have $q\rightarrow-1$ at late time for flat FRW universe. In order to make the behavior of the underlying models more clear, the deceleration parameter $q$ as well as the equation of state parameter $w_D$ for flat and closed universes have been plotted against the redshift parameter, $z$. All of the studied cases admit a transition in the expansion history of universe from a deceleration phase to an accelerated one around $z\approx 0.6$

The systemic functional grammar of Chinese nominal groups: a text-based approach
Creators: name: Fang, Jing
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: For the past two decades, great efforts have been made in the systemic functional description of English and many other languages including Chinese at the clause level. However, very few descriptive work has been done at the group/phrase level. As an attempt to fill in the gap, this thesis extends the lexicogrammatical study to the level of nominal groups, focusing on Mandarin Chinese in particular. Drawing upon a corpus of 180 quality texts of different text types, the investigation is heavily text-based: the nominal groups are observed in the environment of clauses, sentences, paragraphs and texts in contexts. The description of Chinese nominal groups is unfolded on the basis of Halliday’s metafunctional model, exploring the metafunctional resources that Chinese nominal groups provide in realising the three strands of meaning: ideational (including logical and experiential), interpersonal and textual meanings. Through the investigation of each metafunction, some important systems within the nominal group are presented, which provide selections in realising the metafunctional meanings. In terms of logical metafunction, the system of MODIFICATION is presented. In terms of experiential metafunction, the systems presented include THING TYPE, CLASSIFICATION, EPITHESIS, QUALIFICATION, and MEASURE. In terms of interpersonal metafunction, the system of PERSON is introduced. And finally, in terms of textual metafunction, the exploration includes the system of NAMING, the system of IDENTIFICATION, and the system of NUMERATION. Major selections on each of these systems are discussed in detail, with examples demonstrating the potential lexicogrammatical choices. Apart from the exploration of the systems, another focus of the study is on the potential application of the findings to other areas. For this purpose, at the end of each metafunctional exploration, a case study involving different types of texts is presented, demonstrating the significance of nominal groups in their contributions to the metafunctional meanings. The case studies are designed to explore different issues in relation to the use of nominal groups, including the modification structure of the nominal groups and its relation with text types (in the logical exploration), the experiential environment of Thing type choices in different types of texts (in the experiential exploration), the choice of nominal groups in enacting different attitudes (in the interpersonal exploration), and challenges of cohesion and coherence in machine translation presented by nominal groups (in the textual exploration). Through in-depth metafunctional exploration of the nominal gorups, as well as illustrative case studies, this research is expected to contribute to the development of language typology in Systemic Functional Linguistics, as well as other areas including delicate discourse analysis, the study of Chinese language, and machine translation research.

description: In wireless sensor networks, where energy is scarce, it is inefficient to have all nodes active because they consume a non-negligible amount of battery. In this paper we consider the problem of jointly selecting sensors, relays and links in a wireless sensor network where the active sensors need to communicate their measurements to one or multiple access points. Information messages are routed stochastically in order to capture the inherent reliability of the broadcast links via multiple hops, where the nodes may be acting as sensors or as relays. We aim at finding optimal sparse solutions where both, the consistency between the selected subset of sensors, relays and links, and the graph connectivity in the selected subnetwork are guaranteed. Furthermore, active nodes should ensure a network performance in a parameter estimation scenario. Two problems are studied: sensor and link selection; and sensor, relay and link selection. To solve such problems, we present tractable optimization formulations and propose two algorithms that satisfy the previous network requirements. We also explore an extension scenario: only link selection. Simulation results show the performance of the algorithms and illustrate how they provide a sparse solution, which not only saves energy but also guarantees the network requirements.

description: The effects of high magnetic fields applied perpendicular to the spontaneous ferroelectric polarization on single crystals of BiFeO$_3$ were investigated through magnetization, magnetostriction, and neutron diffraction measurements. The magnetostriction measurements revealed lattice distortion of $2\times 10^{-5}$, during the reorientation process of the cycloidal spin order by applied magnetic fields. Furthermore, anomalous changes in magnetostriction and electric polarization at a larger field demonstrate an intermediate phase between cycloidal and canted antiferromagnetic states, where a large magnetoelectric effect was observed. Neutron diffraction measurements clarified that incommensurate spin modulation along [110] direction in the cycloidal phase becomes commensurate in the intermediate phase. Theoretical calculations based on the standard spin Hamiltonian of this material suggest an antiferromagnetic cone-type spin order in the intermediate phase.

description: Hepatocellular carcinoma (HCC) is often diagnosed in patients with advanced disease who are ineligible for curative surgical therapies. Sorafenib is a first-line agent approved for the treatment of advanced HCC. However, the frequent resistance of HCC cells to sorafenib greatly reduces its efficacy. Herein, we describe a novel long non-coding RNA (lncRNA) conferring sorafenib resistance. Long intergenic non-protein coding RNA 1273 (LINC01273) was significantly overexpressed in human HCC and sorafenib-resistant tissues, linking it to poor overall and relapse-free survival. We established sorafenib-resistant Huh7 (Huh7-SR) and SMMC-7721 (SMMC-7721-SR) cells, and found that the knockdown of LINC01273 repressed the viability, colony formation, and DNA synthesis rate of Huh7-SR and SMMC-7721-SR cells. The level of N6-methyladenosine (m6A) in sorafenib-resistant HCC cells was significantly decreased, which was rescued by LINC01273 silencing. Mechanistically, LINC01273 complementarity bound to miR-600, served as a ‘reservoir’ increasing miR-600 stability, and facilitating miR-600 targeting methyltransferase 3 (METTL3), a m6A ‘writer’, resulting in reducing METTL3 level. In addition, LINC01273 was modified with m6A, METTL3 increased LINC01273 m6A modification, followed by LINC01273 decay in the presence of YTHDF2, a m6A ‘reader’. Our findings reveal the key role of LINC01273 in sorafenib-resistant HCC cells, and targeting of the newly identified LINC01273/miR-600/METTL3 feedback regulatory axis may be a promising effective intervention for HCC patients with sorafenib resistance.

description: Background: Fibrotic remodelling in the atria, associated with atrial fibrillation (AF), creates areas of slowed and heterogenous conduction. These areas act as substrates that promote AF maintenance and perpetuation. Hence, detecting these regions is crucial for understanding and managing AF. One promising approach for identifying these regions is the estimation of conduction velocity (CV).

Purpose: In this study, we sought to enhance OpenEP Workbench software for researchers by (1)incorporating three well established method for CV estimation (triangulation, planar fitting, and radial basis function interpolation) and CV divergence calculation to detect conduction disturbances; (2)assess the performance of these three CV calculation methods in identifying fibrotic regions, using simulated data as the ground truth (3)developing a visualisation tool to enable identification of slow conduction regions at the optimal classification threshold attained from (2).

Results: The classification performance of the three CV methods in identifying fibrotic regions were assessed, resulting with the highest accuracy and AUC for the triangulation method (accuracy=78%, AUC=0.88). EP Workbench was enhanced with tools to create 3D surface maps of the generated voltage, CV and divergence parametrised voltage using electro-anatomical mapping data. Additionally, a histogram analysis tool was implemented to identify regions of slow conduction velocity from electroanatomic mapping data. Using a threshold of <0.3m/s, two slow conducting regions can be visualised on the posterior wall of a test case.

Conclusion: The enhanced OpenEP Workbench provides a pre-built pipeline for researcher and clinicians to optimise CV and fibrotic region classifiers and quantify conduction velocity heterogeneity in electro-anatomical mapping data.

description: The frontier orbital sequence of individual dicyanovinyl-substituted oligothiophene molecules is studied by means of scanning tunneling microscopy. On NaCl/Cu(111) the molecules are neutral and the two lowest unoccupied molecular states are observed in the expected order of increasing energy. On NaCl/Cu(311), where the molecules are negatively charged, the sequence of two observed molecular orbitals is reversed, such that the one with one more nodal plane appears lower in energy. These experimental results, in open contradiction with a single-particle interpretation, are explained by a many-body theory predicting a strongly entangled doubly charged ground state.

description: Combining new, low-cost thermal infrared and time-of-flight range sensors provides new opportunities. In this position paper we explore the possibilities of combining these sensors and using their fused data for person detection. The proposed calibration approach for this sensor combination differs from the traditional stereo camera calibration in two fundamental ways. A first distinction is that the spectral sensitivity of the two sensors differs significantly. In fact, there is no sensitivity range overlap at all. A second distinction is that their resolution is typically very low, which requires special attention. We assume a situation in which the sensors' relative position is known, but their orientation is unknown. In addition, some of the typical measurement errors are discussed, and methods to compensate for them are proposed. We discuss how the fused data could allow increased accuracy and robustness without the need for complex algorithms requiring large amounts of computational power and training data.

description: The threat landscape of industrial infrastructures has expanded exponentially over the last few years. Such infrastructures include services such as the smart meter data exchange that should have real-time availability. Smart meters constitute the main component of the Advanced Metering Infrastructure, and their measurements are also used as historical data for forecasting the energy demand to avoid load peaks that could lead to blackouts within specific areas. Hence, a comprehensive Incident Response plan must be in place to ensure high service availability in case of cyber-attacks or operational errors. Currently, utility operators execute such plans mostly manually, requiring extensive time, effort, and domain expertise, and they are prone to human errors. In this paper, we present a method to provide an orchestrated and highly automated Incident Response plan targeting specific use cases and attack scenarios in the energy sector, including steps for preparedness, detection and analysis, containment, eradication, recovery, and post-incident activity through the use of playbooks. In particular, we use the OASIS Collaborative Automated Course of Action Operations (CACAO) standard to define highly automatable workflows in support of cyber security operations for the Advanced Metering Infrastructure. The proposed method is validated through an Advanced Metering Infrastructure testbed where the most prominent cyber-attacks are emulated, and playbooks are instantiated to ensure rapid response for the containment and eradication of the threat, business continuity on the smart meter data exchange service, and compliance with incident reporting requirements.

description: Background: Understanding how temporal and spatial attributes of fire regimes, environmental conditions, and species’ traits interact to shape ecological communities will help improve biodiversity conservation in fire-affected areas. We compared the influence of time since the last fire at a site, and the area and diversity of post-fire successional vegetation surrounding a site (i.e., the “spatial context” of fire), on bird species and functional groups in two ecosystems in south-eastern Australia. These ecosystems, semi-arid “mallee” woodlands and temperate “foothill” forests, differ in stand-regeneration patterns, climate, and topography. For 22 bird species in mallee woodlands, 33 species in foothill forests and four functional groups of birds in both ecosystems, we fitted non-linear models that differed in fire regime predictor variables. Results: In foothill forests, models that included both time since fire and a spatial context variable explained more variation in bird abundances than models that included only time since fire or a spatial variable. In mallee woodlands, the addition of spatial attributes of fire helped explain the occurrence of several species, but this finding was muted when measured across all species. There were key differences between ecosystems in functional group responses to fire regimes. Canopy/upper-midstorey foragers were positively associated with the amount of late-successional vegetation in mallee woodlands, but not in foothill forests. Lower-midstorey foragers showed a decline response to the amount of late-successional vegetation in mallee woodlands and a contrasting incline response in foothill forests. However, lower-midstorey foragers showed a similar response to the amount of surrounding early-successional vegetation in both ecosystems—decreasing in abundance when > 50% of the surrounding vegetation was early-successional. Conclusions: The influence of fire regimes on birds varies among species within sites, across landscapes and between ecosystems. Species’ foraging traits influence bird associations with fire regimes, and help to make sense of a myriad of relationships, but are usefully understood in the context of ecosystem types and the regeneration patterns of their dominant flora. The spatial context of fire regimes is also important—the amount of successional vegetation surrounding a site influences bird abundance. Fire management strategies that incorporate the spatial contexts of fire regimes, as well as the temporal and ecological contexts of fire regimes, will have the greatest benefits for biodiversity.

Impacts of population ageing on China's economy: labor force, savings and consumption
Creators: name: Zhang, Xianling
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: China has been experiencing profound changes in its population due to the three-decade implementation of the one-child policy, including imbalance in sex ratios, low fertility rates, and population ageing. This thesis focuses on the growing significance of population ageing in China and the impacts of ageing on labour force supply, savings and consumptions in the economy. China would witness an accelerating ageing process in the next three decades, even though the government has implemented the new fertility policy in 2016. Using the simulation model based on the data from the Chinese 2010 census, this thesis first examines the changes of fertility rates under sudden policy adjustment – the abolition of its decades-long one-child policy and the implementation of a two-child policy. The results show that the two-child policy makes a significant but temporary effect on fertility rates and annual births in China, which marginally affects the demographic future in the country. The labour force supply in the future would be confronted with a declining in the size and proportion, an ageing process, and increasingly growing costs, which further weaken the competitiveness of the economy in international trades. The thesis also investigates the impacts of ageing on the declining in labour force participation rates using the standardization method, indicating a contribution of 24% to the overall decline in labour force participation rates during 2000-2010. Based on both macro-level data from provincial statistics and micro-level data from the China Family Panel Studies 2011, the study also explores the effects of ageing on savings and consumption. The findings suggest that ageing affects household economic behaviours through two mechanisms, one of which negatively affects savings and consumption through an ageing population structure, and the other of which positively increases savings and consumption by supporting elderly parents in the family. These findings deepen the understanding of the relationship between population ageing and the economy, and extend the application of related theories in the case of China. The thesis provides evidence-based analysis that will contribute to the evaluation and formulation of further economic reforms under a rapidly ageing demographic condition in the country.

description: This study proposes a framework to evaluate the performance of borehole arrangements for the design of rectangular shallow foundation systems under spatially variable soil conditions. Performance measures are introduced to quantify, for a fixed foundation layout and given soil sounding locations, the variability level of the foundation system bearing capacities in terms of their mean values and standard deviations. To estimate these measures, the recently proposed random failure mechanism method (RFMM) has been adopted and extended to consider any arrangement of rectangular foundations and boreholes. Hence, three-dimensional bearing capacity estimation under spatially variable soil can be efficiently performed. Several numerical examples are presented to illustrate the applicability of the proposed framework, including diverse foundation arrangements and different soil correlation structures. Overall, the proposed framework represents a potentially useful tool to support the design of geotechnical site investigation programs, especially in situations where very limited prior knowledge about the soil properties is available.

description: Environmental governance aims to reconcile an expanding set of societal objectives at ever-larger scales despite the challenges that remain in integrating conservation and development at smaller scales. We interrogate Solomon Islands’ engagement in the Coral Triangle Initiative on Coral Reefs, Fisheries and Food Security to contribute new insight on the scalar politics of multi-level marine governance. We show how regional objectives are re-interpreted and prioritized as they translate into national policy and practice. Our data suggest that enhanced coordination of finances and activities, integration of objectives in shared protocols and priority geographies, and a subtle shift in power relations between the state, donors, and implementation partners have resulted from processes of re-scaling. We discuss important procedural adjustments in cross-level and cross-scale governance across jurisdictional, institutional, and sectoral scales. We also reflect on the changing role of national governments in shifts toward large-scale, multi-national initiatives.

description: Macrospicules (MS) are localised small-scale jet-like phenomena in the solar atmosphere, which have the potential to transport considerable amount of momentum and energy from the lower solar atmospheric regions to the Transition Region and the low corona. A detailed statistical analysis of their temporal behaviour and spatial properties is carried out in this work. By means of state-of-the-art spatial and temporal resolution observations, yielded by the Atmospheric Imaging Assembly (AIA) of Solar Dynamics Observatory (SDO), we constructed a database covering a 5.5-year long period, containing 301 macrospicules that occurred between June 2010 and December 2015 detected at 30.4 nm wavelength. Here, we report the long-term variation of the height, length, average speed and width of MS in Coronal Holes and Quiet Sun areas both in the northern and southern hemisphere of the Sun. This new database helps to refine our knowledge about the physical properties of MS. Cross-correlation of these properties show a relatively strong correlation, but not always a dominant one. However, a more detailed analysis indicates a wave-like signature in the behaviour of MS properties in time. The period of these long-term oscillatory behaviours are just under two years. Also, in terms of solar north/south hemispheres, a strong asymmetry was found in the spatial distribution of MS properties, which may be accounted for the solar dynamo. This latter feature may then indicate a strong and rather intrinsic link between global internal and local atmospheric phenomena in the Sun.
Conceptualisation of grassroots public diplomacy in Australia and China

description: The term Public Diplomacy (PD) has many definitions, most of which associate it with the state. Recently civil society has been drawn into definitions of PD but is often viewed as audience rather than actor. Whether related to citizens or civil society, PD has not been adequately theorised and therefore this project develops it conceptually under the rubric of "grassroots public diplomacy" (GPD), it does so by comparing its conceptualisation and practice in Australia and China where approaches are dissimilar. The thesis establishes similarities and differences in GPD conceptualisation in the two countries by comparing the data collected by means of semi-structured interviews of experts and practitioners in this field in Australia and China respectively, as well as documentary data related to the concept. A salient characteristic of what has been called GPD here is that it will have a recognisable dialogic approach. Therefore a key question that is answered is whether a dialogic approach was adopted in the processes employed in the case that was studied – and how the dialogic approach manifested itself. The case study employed semi-structured interviews of organisers, speakers, sponsors and randomly selected participants, as well as participant observation and relevant online data. Drawing on Habermas' communicative action theory, the sets of data were analysed using the method of qualitative content analysis. Broad findings suggest that GPD in Australia and China both consist of actors, aims, plans of action, communication acts, coordination, agreement, processes and results. There are both similarities and differences that the study has identified between the conceptualisation of CPD in the two states. The inclusion of a dialogic approach is also confirmed in the case study, in process segments identified as three interconnected phases of 'first', 'following' and 'further' interactions.
The effect of X-ray dust-scattering on a bright burst from the magnetar 1E 1547.0-5408

description: A bright burst, followed by an X-ray tail lasting ~10 ks, was detected during an XMM-Newton observation of the magnetar 1E 1547.0-5408 carried out on 2009 February 3. The burst, also observed by SWIFT/BAT, had a spectrum well fit by the sum of two blackbodies with temperatures of ~4 keV and 10 keV and a fluence in the 0.3-150 keV energy range of ~1e-5 erg/cm2. The X-ray tail had a fluence of ~4e-8 erg/cm2. Thanks to the knowledge of the distances and relative optical depths of three dust clouds between us and 1E 1547.0-5408, we show that most of the X-rays in the tail can be explained by dust scattering of the burst emission, except for the first ~20-30 s. We point out that other X-ray tails observed after strong magnetar bursts may contain a non-negligible contribution due to dust scattering.

description: The understandability of process models has been subject to extensive research in which eye-tracking has demonstrated great capability to deliver meaningful insights. However, the full potential of this technology is not fully exploited due to the complexity of using dynamic stimuli in experiments (i.e., large and interactive process models) and the common use of static stimuli (i.e., small non-interactive models) as a cheap alternative limiting the ecological validity of the used experimental setting and the generalizability of the results. This paper presents EyeMind, a solution to overcome this limitation by supporting the whole experimental workflow using dynamic stimuli and offering a comprehensive analysis toolkit of eye-tracking data. All these features facilitate experiments on large and interactive process models as well as the extraction of meaningful insights.

description: Catalysts are quantum systems that open up dynamical pathways between quantum states which are otherwise inaccessible under a given set of operational restrictions while, at the same time, they do not change their quantum state. We here consider the restrictions imposed by symmetries and conservation laws, where any quantum channel has to be covariant with respect to the unitary representation of a symmetry group, and present two results. First, for an exact catalyst to be useful, it has to build up correlations to either the system of interest or the degrees of freedom dilating the given process to covariant unitary dynamics. This explains why catalysts in pure states are useless. Second, if a quantum system (“reference frame”) is used to simulate to high precision unitary dynamics (which possibly violates the conservation law) on another system via a global, covariant quantum channel, then this channel can be chosen so that the reference frame is approximately catalytic. In other words, a reference frame that simulates unitary dynamics to high precision degrades only very little.
