description: CERN-LHC. ALICE. Multiplicity ($N_{\mathrm{ch}}$) distributions and transverse momentum ($p_{\mathrm{T}}$) spectra of inclusive primary charged particles in the kinematic range of $|\eta| < 0.8$ and $0.15\ \mathrm{GeV}/c < p_{\mathrm{T}} < 10\ \mathrm{GeV}/c$ are reported for pp, p-Pb, Xe-Xe and Pb-Pb collisions at centre-of-mass energies per nucleon pair ranging from $\sqrt{s_\mathrm{NN}} = 2.76\ \mathrm{TeV}$ up to $13\ \mathrm{TeV}$. The multiplicity distributions are also shown in their KNO-scaled form. The correlation between the transverse momentum of primary charged particles and the charged-particle multiplicity of the corresponding collision is reported in fine intervals. In addition, the mean $ \langle p_{\mathrm{T}} \rangle $ and standard deviation $ \sigma(p_{\mathrm{T}}) $ derived from these multiplicity dependent $p_\mathrm{T}$ spectra are shown as a function of $N_{\mathrm{ch}}$. The relative standard deviation $ \sigma(p_{\mathrm{T}}) / \langle p_{\mathrm{T}} \rangle $ of the spectra is reported as well. All observables are also presented as a function of the reltaive multiplicity $ N_{\mathrm{ch}}\ / \langle N_{\mathrm{ch}} \rangle $. Note that $ \langle N_{\mathrm{ch}} \rangle $ is calculated for the whole multiplicity range extending beyond the $N_{\mathrm{ch}}$ values reported for the multiplicity-differential observables. Also the transverse momentum spectra integrated over this full range of multiplicities are presented. The mean and standard deviation derived from these multiplicity-integrated $p_\mathrm{T}$ spectra are used to normalize the corresponding multiplicity-dependent values which are then reported as a function of $ N_{\mathrm{ch}}\ / \langle N_{\mathrm{ch}} \rangle $.

We show that the diffusivity can be enhanced by many orders of magnitude at appropriate choice of the forcing amplitude and frequency. The diffusivity demonstrates TAD, abnormal (decreasing) temperature dependence at forcing amplitudes exceeding certain value. At any fixed forcing frequency $Ω$ normal temperature dependence of the diffusivity is restored at low enough temperatures, $T

Communication strategies in interactions involving language learners

Subjects: Other education not elsewhere classified

description: Because of globalisation and government policy, English language learning and teaching has become an increasingly central part of education in Japan. Policy settings have asserted the primacy of effective communication,and emphasised the use of English as a lingua franca. However, this is not well reflected in English language teaching practices, nor in student outcomes. In order to support improved learning and teaching, there is therefore a need to better understand the communicative behaviours that facilitate communicative success in interactions between native and non-native speakers of English. This study explores communication strategies in interactions involving Japanese speaking learners of English and a native English speaker. It employs the principles and practices of conversation analysis to analyse 15 interactions involving 8 Japanese learners of English and one native English speaker. Participants were asked to complete a communication task where the native speaker needed to gather information from the non-native speaker. It focuses on the use of next-turn repetition by the Japanese-speaking learners to accomplish confirmation and other-initiation of repair. With these practices, they facilitate completion of the communication task, but also generate opportunities for language learning. The findings of this study add to our understanding of communication strategies in interactions involving native and non-native speakers of English, and demonstrate the possible value of a communicative and interactional approach to language learning and teaching in Japan.

description: Formation, emission and lasing properties of strain-free InP(As)/AlInAs quantum dots (QDs) embedded in AlInAs microdisk (MD) cavity were investigated using transmission electron microscopy and photoluminescence (PL) techniques. In MD structures, the QDs having nano-pan-cake shape have height of ~2 nm, lateral size of 20-50 nm and density of ~5x109 cm-2. Their emission observed at ~940 nm revealed strong temperature quenching, which points to exciton decomposition. It also showed unexpected type-I character indicating In-As intermixing, as confirmed by band structure calculations. We observed lasing of InP(As) QD excitons into whispering gallery modes in MD having dimeter ~3.2 mkm and providing free spectral range of ~27 nm and quality factors up to Q~13000. Threshold of ~50 W/cm2 and spontaneous emission coupling coefficient of ~0.2 were measured for this MD-QD system.
Incorporating user rating credibility in recommender systems

Subjects: Other education not elsewhere classified

description: There has been a lot of research efforts aimed at improving the recommendation accuracy with Collaborative Filtering (CF); yet there is still a lack of investigation into the integration of CF algorithms with the analysis of users' rating behaviors. Considering that by incorporating the rating credibility, the impact of the ratings given by neighbors with low credibility should be decreased. In this work, we develop an integrated solution for CF recommendation by incorporating the credibility of users' ratings, demographic information of the people, and ontological semantics of items. The demographic information of users and ontological semantics of items are used in the similarity measurement of users/items to alleviate the issues of sparsity and cold-start in CF algorithms. To our knowledge, this is the first time an integration of the rating credibility, demographic information of users, and ontological semantics of items is created in order to improve the performance of CF recommendation system. Experiments are conducted on the real-world datasets of MovieLens and Yahoo!Movie. Comparing with baseline methods, the experimental results show that the proposed approach significantly improves the quality of recommendation in terms of accuracy, precision, recall, F-measure, and standard deviation of the errors.

description: We present a phenomenological theory of filamentary resistive random access memory (RRAM) describing the commonly observed features of their current-voltage characteristics. Our approach follows the approach of thermodynamic theory developed earlier for chalcogenide memory and threshold switches and largely independent of their microscopic details. It explains, without adjustable parameters, such features as the domains of filament formation and switching, voltage independent current in SET and current independent voltage in RESET regimes, the relation between the set and reset voltages, filament resistance independent of its length, etc. Furthermore, it expresses the observed features through the material and circuitry parameters thus paving a way to device improvements.

How does online therapy work?: Exploring skills usage as a mechanism of change in internet-delivered cognitive-behavioural therapy for depression and anxiety
Creators: name: Terides, Matthew Dean
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Major depression and generalised anxiety disorder (GAD) are common disorders that are often comorbid. Cognitive-Behavioural Therapy (CBT) is an efficacious treatment, which can be delivered online (iCBT), but little is known about its mechanism of therapeutic change. Understanding mechanisms will help improve treatment efficacy and efficiency. A core feature of CBT is teaching patients skills that promote adaptive cognitions and behaviours. However, there is limited evidence indicating that skills usage is a mechanism of change during CBT. The present thesis aims to evaluate the mechanistic role of CBT skills usage on symptoms of depression and GAD during iCBT. The aim of study one was to develop a brief questionnaire assessing CBT skills usage suitable for mechanism research. Responses from 661 participants were subjected to exploratory and confirmatory factor analysis yielding a 12-item measure of CBT skills usage, the Frequency of Actions and Thoughts Scale (FATS). In study two, the FATS was administered during an iCBT course for depression and anxiety (n = 125). Large increases in FATS scores were observed from pre-treatment to post-treatment (d = 0.90), and residualised change scores correlated significantly with residual change scores of symptoms (rs = .28 - .30). The third study utilised a randomised controlled trial investigating the causal relationship between treatment and skills usage. Results indicated that patients receiving iCBT for depression and anxiety (n = 65) reported significantly greater FATS scores (d = 0.58) at the end of treatment compared with a wait-list control group (n = 66). Mediation analysis revealed that symptom reduction was mediated by increased skills usage at the end of treatment. Study four pooled the data from studies two and three, which was used to explore predictors of skills usage. Overall, the results from this research suggest that skills usage is an important mechanism of change in iCBT for depression and GAD.

description: Perturbations and eikonal instabilities of black holes and branes in the Einstein-Gauss-Bonnet theory and its Lovelock generalization were considered in the literature for several particular cases, where the asymptotic conditions (flat, dS, AdS), the number of spacetime dimensions $D$, non-vanishing coupling constants ($α_1$, $α_2$, $α_3$ etc.) and other parameters have been chosen in a specific way. Here we give a comprehensive analysis of the eikonal instabilities of black holes and branes for the \emph{most general} Lovelock theory, not limited by any of the above cases. Although the part of the stability analysis is performed here purely analytically and formulated in terms of the inequalities for the black hole parameters, the most general case is treated numerically and the accurate regions of instabilities are presented. The shared Mathematica(R) code allows the reader to construct the regions of eikonal instability for any desired values of the parameters.

description: Optical properties of color centers in diamond have been the subject of intense research due to their promising applications in quantum photonics. In this work we study the optical properties of Xe related color centers implanted into nitrogen rich (type IIA) and an ultrapure, electronic grade diamond. The Xe defect has two zero phonon lines at ~ 794 and 811 nm, which can be effectively excited using both green and red excitation, however, its emission in the nitrogen rich diamond is brighter. Near resonant excitation is performed at cryogenic temperatures and luminescence is probed under strong magnetic field. Our results are important towards the understanding of the Xe related defect and other near infrared color centers in diamond.

description: The aim of this work was to further investigate the anticancer potential of Juglans mandshurica Maxim, including the separation of active constituents and their anti-proliferative effects with underlying mechanism of action. Five alkaloids (1–5) were isolated from the bark of J. mandshurica. Among them, 1 showed the highest cytotoxic activities against Hep3B and HepG2 cells with an IC50 values of 61.80 and 56.24 μM, respectively. Therefore, the cellular mechanism involved 1 was subsequently studied. Our results showed that 1 markedly caused apoptosis and autophagy, but without cell cycle arrest in HepG2 cells. Interestingly, only autophagic cell death was induced in 1-treated Hep3B cells. It is concluded that the isolated alkaloids exerted a certain anti-hepatoma potential, and our results may provide a basis for the further investigation of the alkaloids extracted from J. mandshurica.

description: When a Dirac semimetal is subject to a circularly polarized laser, it is predicted that the Dirac cone splits into two Weyl nodes and a nonequilibrium transient state called the Floquet Weyl semimetal is realized. We focus on the previously unexplored low-frequency regime, where the upper and lower Dirac bands resonantly couple with each other through multi-photon processes, which is a realistic situation in solid state ultrafast pump-probe experiments. We find a series of new Weyl nodes emerging in pairs when the Floquet replica bands hybridize with each other. The nature of the Floquet Weyl semimetal with regard to the number, locations, and monopole charges of these Weyl nodes is highly tunable with the amplitude and frequency of the light. We derive an effective low energy theory using Brillouin-Wigner expansion and further regularize the theory on a cubic lattice. The monopole charges obtained from the low-energy Hamiltonian can be reconciled with the number of Fermi arcs on the lattice which we find numerically.

description: Solar filaments can be formed via chromospheric evaporation followed by condensation in the corona or by the direct injection of cool plasma from the chromosphere to the corona. In this paper, with high-resolution H$α$ data observed by the 1.6 m New Solar Telescope of the Big Bear Solar Observatory on 2015 August 21, we confirmed that an active-region filament is maintained by the continuous injection of cold chromospheric plasma. We find that the filament is rooted along a bright ridge in H$α$, which corresponds to the intersection of a magnetic quasi-separatrix layer with the solar surface. This bright ridge consists of many small patches and the sizes of these patches are comparable to the width of the filament threads. It is found that upflows originate from the brighter patches of the ridge, whereas the downflows move toward the weaker patches of the ridge. The whole filament is composed of two opposite directional streams, implying that longitudinal oscillations are not the only cause of the counterstreamings, and unidirectional siphon flows with alternative directions are another possibility.

description: We present hydrodynamic and magneto-hydrodynamic simulations of liquid sodium flow with the PLUTO compressible MHD code to investigate influence of magnetic boundary conditions on the collimation of helicoidal motions. We use a simplified cartesian geometry to represent the flow dynamics in the vicinity of one cavity of a multi-blades impeller inspired by those used in the Von-Kármán-Sodium (VKS) experiment. We show that the impinging of the large scale flow upon the impeller generates a coherent helicoidal vortex inside the blades, located at a distance from the upstream blade piloted by the incident angle of the flow. This vortex collimates any existing magnetic field lines leading to an enhancement of the radial magnetic field that is stronger for ferromagnetic than for conducting blades. The induced magnetic field modifies locally the velocity fluctuations, resulting in an enhanced helicity. This process possibly explains why dynamo action is more easily triggered in the VKS experiment when using soft iron impellers.

description: Hikikomori has been recognized as a significant social issue in Japan. It is a Japanese term that refers to young people (aged 18-39 years) who have been in an asocial state of social withdrawal and social isolation for over six months. The Cabinet Office of Japan suggests that the number of hikikomori youth has reached approximately 700,000 and is still growing. In addition, recent surveys suggest that hikikomori has a prolonged influence, such that more than 610,000 middle-aged people (aged 40-65 years) have remained in a hikikomori state which began at a younger age. The major challenge of this issue facing experts is that Hikikomori individuals usually repulse external support or interventions, either consciously or unconsciously. Hence, psychological therapies reliant on external interventions have inevitable limitations in curing hikikomori. Our methodology of C-BED (Community-Based Enterprise Development), on the other hand, has proven effective in overcoming this challenge, based on the results of our pilot study supported by Japanese NGO and TOYOTA Foundation. C-BED is a peer-to-peer learning process in which hikikomori share their thoughts with peers in similar situations through online dialogues. In developing the original program, we adopted the Dialectic Behavior Therapy (DBT) to the C-BED and produced 10 online modules for participants to interact by using online SNS group chat. The results of the online workshops (online C-BED) for five Hikikomori youth suggested that their psychological anxiety has been decreased and their willingness to participate socially has been strengthened after attending a 3-course module. In addition, C-BED has incomparable advantages in approaching hikikomori in remote areas at a meager cost, and in bringing positive changes to those who are struggling with psychological problems, no matter their cultural or economic backgrounds.

description: Since the discovery of nuclear gamma-rays, its imaging has been limited to pseudo imaging, such as Compton Camera (CC) and coded mask. Pseudo imaging does not keep physical information (intensity, or brightness in Optics) along a ray, and thus is capable of no more than qualitative imaging of bright objects. To attain quantitative imaging, cameras that realize geometrical optics is essential, which would be, for nuclear MeV gammas, only possible via complete reconstruction of the Compton process. Recently we have revealed that "Electron Tracking Compton Camera" (ETCC) provides a well-defined Point Spread Function (PSF). The information of an incoming gamma is kept along a ray with the PSF and that is equivalent to geometrical optics. Here we present an imaging-spectroscopic measurement with the ETCC. Our results highlight the intrinsic difficulty with CCs in performing accurate imaging, and show that the ETCC surmounts this problem. The imaging capability also helps the ETCC suppress the noise level dramatically by ~3 orders of magnitude without a shielding structure. Furthermore, full reconstruction of Compton process with the ETCC provides spectra free of Compton edges. These results mark the first proper imaging of nuclear gammas based on the genuine geometrical optics.

description: Sustainability has opened up new growth avenues for the corporate sector, even during the times of global recession. Firms are now aiming to incorporate the concept of sustainability in their supply chains. However, lack of practical measures, which could address all three dimensions of sustainability - social, environmental and economic - is the main obstacle in achieving this objective. Thus, it is imperative to develop a reliable and valid scale for sustainable supply chain management (SSCM) which can further theory construction. This PhD study treated SSCM as a broader phenomenon and developed valid and reliable scales for sustainable planning, procurement, manufacturing, transportation, and warehousing. Qualitative data analysis (QDA) techniques and methodologies were used to review SSCM material consisting of 349 academic articles, books, industry publications and company reports. Various dimensions and measures were developed for SSCM sub-constructs and translated in the form of a questionnaire. Data was collected from 215 firms in the Australian food industry, and subjected to rigorous quantitative analysis using structural equation modelling (SEM) to ensure validity and reliability of each SSCM scale. The study has made five major contributions: (1) it has developed a valid and reliable sustainability scale for each process of a focal firm's supply chain; (2) it presents a set of best practices for each stage of the food supply chain; (3) it has developed an inventive framework for construct conceptualisation and measures identification; (4) it has conducted a thorough review of SSCM literature through the lens of the Supply Chain Operations Reference (SCOR) process model; (5) it also shows that the use of qualitative data analysis (QDA) software makes it possible to organise and analyse voluminous data in a strategic manner.
Quantifying damage to coral colonies by waterborne debris during hydrodynamic disturbances

description: Physical bombardment by waterborne debris is a common disturbance in shallow coral reef systems. During hydrodynamic disturbances, such as tropical storms, increases in water velocity elevate drag forces acting on objects—ranging in size from sand to boulders and coral colonies—dislodging and propelling them into nearby coral colonies. Impact by debris can cause a number of injuries, ranging from intra-colony damage (e.g., branch breakage or tissue death) to whole-colony dislodgment. However, the bombardment process is poorly understood, given that it is difficult to observe in situ as hydrodynamic disturbances occur. Using 3D coral scans representing five characteristically different growth forms and finite element analysis, I simulated bombardment scenarios by applying increasing point forces to colony meshes. I measured the force required to cause breakage and where that breakage occurred, and found high rates of intra-colony breakage (a mean of 23% across growth forms). There was a significant interaction between colony surface area to volume ratios (SA:V) and the damage outcome (branch breakage or whole-colony dislodgement), but generally the impact force necessary to result in damage decreased as SA:V increased. Traditional models of coral damage during storms only consider hydrodynamic force, however, the results presented here show that bombardment may be the dominant process damaging and killing reef corals during hydrodynamic disturbances.
The iconography of the images in the magical papyri

description: The aim of this thesis is to demonstrate that the figural depictions in the magical papyri formed part of a conceptualised system of magical imagery. Rather than being haphazard sketches, it will be argued that the figural depictions were meaningful images, whose execution and use in rites and spells reflect considered ritualistic actions. Using PGM XXXVI as a case study, it will be established that the depictions were governed by a strict set of iconographic regulations. Specific terminology, uniform compositional placement, a desire to execute the depictions accurately, as well as recurring pictorial motifs, suggest that the images existed within a pre-established iconographic system. In addition, the depictions appear to have retained specific functions within the magical papyri. These functions were accordingly fluid and changed relative to the context of the depictions' use (whether in applied magic or magical handbooks). As such, the depictions were utilised as part of the materiality of magic praxis. Finally, it will be demonstrated that the figural depictions were considered significant in the belief and practice of Graeco-Egyptian magic. This is indicated by the images' complex relationship with magical practitioners, wherein they enacted as intermediaries between the mundane and supernatural worlds. Moreover, the ritual act of drawing the depictions in magical praxis suggests that they were fundamental elements in the enactment of particular rites and spells.
Study of smoke protection measures within high rise apartments

description: This thesis intends to develop an understanding of stair pressurisation systems in high-rise residential buildings, to provide information regarding the performance of such systems in a credible evacuation scenario. Stair pressurisation systems are designed to create a smoke-proof barrier, preventing the ingress of smoke into staircases within buildings over 25m tall. Currently, all stair pressurisation systems are designed with the same commissioning requirements in mind, regardless of other factors such as height or evacuation strategies. In tall buildings, evacuation strategies can utilise phased or simultaneous evaluation of of numerous storeys at once. Given that the number of doors open into a stair in a credible evacuation of a building exceeds the the number required to be open during system commissioning, it is possible that such a system may not perform as intended when it is required the most. This report examines the performance of a stair pressurisation with a differing number of doors open into the shaft in order to determine performance as the number of doors open at once increases. Simulations using FDS have shown that a system that would pass commissioning requirements allows smoke in the shaft if there are more than 4 doors open simultaneously, signifying the evacuation of three storeys simultaneously. Past this limit, the amount of smoke which leaks into the staircases continues to increase as more door open. Overall, the simulations conducted show a disconnect between the Australian legislation for the commissioning of smoke control systems and the evacuation methodology used in taller buildings, signifying a need to create an interface between the commissioning of systems and credible scenarios in an emergency.

description: Particle filtering is a numerical Bayesian technique that has great potential for solving sequential estimation problems involving non-linear and non-Gaussian models. Since the estimation accuracy achieved by particle filters improves as the number of particles increases, it is natural to consider as many particles as possible. MapReduce is a generic programming model that makes it possible to scale a wide variety of algorithms to Big data. However, despite the application of particle filters across many domains, little attention has been devoted to implementing particle filters using MapReduce. In this paper, we describe an implementation of a particle filter using MapReduce. We focus on a component that what would otherwise be a bottleneck to parallel execution, the resampling component. We devise a new implementation of this component, which requires no approximations, has $O\left(N\right)$ spatial complexity and deterministic $O\left(\left(\log N\right)^2\right)$ time complexity. Results demonstrate the utility of this new component and culminate in consideration of a particle filter with $2^{24}$ particles being distributed across $512$ processor cores.

description: We study the redshift evolution of the quasar UV Luminosity Function (LF) for 0.5 < z < 6.5, by collecting the most up to date observational data and, in particular, the recently discovered population of faint AGNs. We fit the QSO LF using either a double power-law or a Schechter function, finding that both forms provide good fits to the data. We derive empirical relations for the LF parameters as a function of redshift and, based on these results, predict the quasar UV LF at z=8. From the inferred LF evolution, we compute the redshift evolution of the QSO/AGN comoving ionizing emissivity and hydrogen photoionization rate. If faint AGNs are included, the contribution of quasars to reionization increases substantially. However, their level of contribution critically depends on the detailed shape of the QSO LF, which can be constrained by efficient searches of high-z quasars. To this aim, we predict the expected (i) number of z>6 quasars detectable by ongoing and future NIR surveys (as EUCLID and WFIRST), and (ii) number counts for a single radio-recombination line observation with SKA-MID (FoV = 0.49 deg^2) as a function of the Hnalpha flux density, at 0
