description: Electron acceleration to non-thermal energies is known to occur in low Mach number (M<5) shocks in galaxy clusters and solar flares, but the electron acceleration mechanism remains poorly understood. Using two-dimensional (2D) particle-in-cell (PIC) plasma simulations, we showed in Paper I that electrons are efficiently accelerated in low Mach number (M=3) quasi-perpendicular shocks via a Fermi-like process. The electrons bounce between the upstream region and the shock front, with each reflection at the shock resulting in energy gain via shock drift acceleration. The upstream scattering is provided by oblique magnetic waves, that are self-generated by the electrons escaping ahead of the shock. In the present work, we employ additional 2D PIC simulations to address the nature of the upstream oblique waves. We find that the waves are generated by the shock-reflected electrons via the firehose instability, which is driven by an anisotropy in the electron velocity distribution. We systematically explore how the efficiency of wave generation and of electron acceleration depend on the magnetic field obliquity, the flow magnetization (or equivalently, the plasma beta), and the upstream electron temperature. We find that the mechanism works for shocks with high plasma beta (>20) at nearly all magnetic field obliquities, and for electron temperatures in the range relevant for galaxy clusters. Our findings offer a natural solution to the conflict between the bright radio synchrotron emission observed from the outskirts of galaxy clusters and the low electron acceleration efficiency usually expected in low Mach number shocks.

‘We had seen with our own eyes’: A cultural history of humanitarian and Australian feminist responses to the social and moral conditions of indentured Indian labour in Fiji, 1910s
Creators: name: Claridge, Suzanne

Subjects: Other education not elsewhere classified

description: In 1916, Christian missionaries Charles Freer Andrews and William Winstanley Pearson published a report that investigated the conditions of indentured labour in Fiji. Their report garnered significant attention in Australia, particularly among humanitarian and feminist organisations. In response to their report, Florence Garnham, on behalf of combined women’s organisations across Australia and New Zealand, conducted an inquiry in Fiji and published A Report on the Social and Moral Conditions in Fiji in 1918. By focusing on how Andrews and Pearson were oriented towards the problem of indenture and how their report engaged an Australian feminist response, this thesis explores how different humanitarian sensibilities were oriented towards the problem of indentured Indian labour in Fiji during the 1910s.

description: Radon gas emanating from materials is of interest in environmental science and also a major concern in rare event non-accelerator particle physics experiments such as dark matter and double beta decay searches, where it is a major source of background. Notable for dark matter experiments is the production of radon progeny recoils (RPRs), the low energy (~100 keV) recoils of radon daughter isotopes, which can mimic the signal expected from WIMP interactions. Presented here are results of measurements of radon emanation from detector materials in the 1 metre cubed DRIFT-II directional dark matter gas time projection chamber experiment. Construction and operation of a radon emanation facility for this work is described, along with an analysis to continuously monitor DRIFT data for the presence of internal 222Rn and 218Po. Applying this analysis to historical DRIFT data, we show how systematic substitution of detector materials for alternatives, selected by this device for low radon emanation, has resulted in a factor of ~10 reduction in internal radon rates. Levels are found to be consistent with the sum from separate radon emanation measurements of the internal materials and also with direct measurement using an attached alpha spectrometer. The current DRIFT detector, DRIFT-IId, is found to have sensitivity to 222Rn of 2.5 μBq/l with current analysis efficiency, potentially opening up DRIFT technology as a new tool for sensitive radon assay of materials.

description: We study strong coupling between plasmons in monolayer charge-doped graphene and excitons in a narrow gap semiconductor quantum well separated from graphene by a potential barrier. We show that the Coulomb interaction between excitons and plasmons result in mixed states described by a Hamiltonian similar to that for exciton-polaritons and derive the exciton-plasmon coupling constant that depends on system parameters. We calculate numerically the Rabi splitting of exciton- plasmariton dispersion branches for several semiconductor materials and find that it can reach values of up to 50 - 100 meV.

description: Abstract We empirically study the relationship between the gender composition and the performance of teams. In our setting, teams of students are incentivized to develop business plans as part of a compulsory course in a business administration program. At first sight, and in line with earlier empirical literature, the gender composition seems to matter. Our article differs in that we have access to a measure of task-specific individual ability. When controlling for ability, the relation between gender and team performance vanishes, highlighting the importance of controlling for other characteristics in empirical and experimental studies of gender effects. Objective: While various studies document a relationship between the gender composition and the performance of teams, we ask whether such findings may depend on a lack of controlling for other dimensions of heterogeneity among team members. Methods: In our setting, teams of students are incentivized to develop business plans as part of a compulsory course in a business administration program. Our article differs from the literature in that we have access to a measure of task-specific individual ability. Using ordinary least squares regressions, controlling for year and team size fixed effects, and conducting various robustness checks, we study the association between team performance and team characteristics. Results: At first sight, and in line with earlier empirical literature, the gender composition seems to matter for team performance. However, when controlling for the individual abilities of team members, the relation between the gender composition and team performance vanishes.

description: The aim of the study was to evaluate the effects of diabetes on episodic memory and working memory after controlling for other comorbidities and several demographic and biological variables. We conducted a cross-sectional study with 1656 participants. From this sample, 100 were diagnosed with type 2 diabetes mellitus. This group was compared with participants without diabetes matched by age, education and sex. Hierarchical regression analyses revealed that after controlling for demographic variables (age, sex, years of education, vocabulary scores, Mini-Mental State Exam scores and Beck Depression Inventory scores) and biological variables (body mass index, glucose, cholesterol, triglycerides, heart rate, systolic blood pressure and diastolic blood pressure), the diabetes status significantly predicted recollection (β = .62), recognition (β = .28), verbal working memory in low (β = .39) and high (β = .29) difficulty tasks, spatial working memory in low (β = .32) and high (β = .38) difficulty tasks, and speed in verbal high difficulty tasks (β = −.33) and spatial low difficulty (β = −.30) working memory tasks. The most essential memory processes for autonomous everyday living are widely affected in diabetic individuals free from other comorbidities despite the administration of glycemic medication.

description: After the discovery of a Higgs boson at the LHC, the next important step is to measure its couplings to fermions and bosons to unravel its true nature. In order to ultimately test the shape of the scalar potential that triggers the electroweak symmetry breaking, it is crucial to measure the triple Higgs coupling at the LHC. We then review the theoretical predictions of the main Standard Model Higgs pair production mechanisms that are needed for such a measurement and present the latest developments in the phenomenological analyses in view of a high luminosity LHC.

description: A microscopic theoretical approach based on a self-consistent density functional theory for the nuclear ground state and QRPA formalism extended with multi-phonon degrees of freedom for the nuclear excited states is implemented in investigations of new low-energy modes called pygmy resonances. Advantage of the method is the unified description of low-energy multiphonon excitations, pygmy resonances and core polarization effects. This is found of crucial importance for the understanding of the fine structure of nuclear response functions at low energies. Aspects of the precise knowledge of nuclear response functions around the neutron threshold are discussed in a connection to nucleosynthesis.

description: Reminiscence therapy is garnering attention for stimulating seniors’ cognitive functions. It could be inferred that that synergistic effects could be created by combining virtual reality (VR), which can project realistic images, with recall, which stimulates memory. We hypothesized that by projecting realistic memories to stimulate recall, VR-based reminiscence therapy would stimulate cognitive function better than conventional photo-based reminiscence therapy. We randomly assigned total 52 people with mild cognitive impairment to eight weeks of reminiscence therapy using either tablet VR panoramas or conventional still photos with 26 participants in each group. Before and after therapy, we tested their cognitive functions with the mini-mental state examination (MMSE), the revised PGC morale scale, multidimensional observation scale for elderly subjects, trail making tests A and B, and the word fluency test. The total scores of MMSE showed improvement for both groups, but did not show statistical significance of the VR panoramas group over the conventional still photos group. However, of the two groups, only the VR panoramas group showed considerable improvement from the baseline. In addition, the analysis of secondary outcome showed that the revised PGC morale scale scores rose considerably higher in the VR panoramas group than in the still photos group. No definite differences were observed in other scales. Contrary to our primary hypothesis, reminiscence therapy produced cognitive improvement regardless of whether its stimuli were still photos or VR panoramas. However, the greater improvement in VR participants’ revised PGC morale scale scores shows enhancement of patients’ subjective well-being.
A Tale of Software Citation Pitfalls

description: Open Science contributes in many ways to a Knowledge Ecology. Opening research data and software to scientific and scholarly communities increases not only the transparency of results, but also facilitates the reuse of research artifacts. Citations are recognized as one of the key incentives to make data and software available, as credit is being transmitted to data producers and software developers. Research data and software citations make research results transparent and verifiable but they are hard to track, because there is no commonly-shared citation standard across communities. To combat this issue, FORCE11 proposed a set of data and software citation principles as guidance for authors which highlight that credit should be given via formal data and software citations using unique and persistent identifiers (PIDs). Despite their efforts, adoption of citation principles has been advancing slowly, and current citation practices remain idiosyncratic and thus hard to track. This poster demonstrates common pitfalls of software citation practices in the scholarly writing process, which complicate the tracking of software citations: (a) not citing software at all, (b) mentions of the software name only as part of the full text, (c) citing a URL related to software rather than a software PID, and (d) citations to software-related research publications or software papers, which are not trackable by data citation discovery services. These pitfalls result in failure to transmit credit. This poster will introduce one aspect of the interactive game “FAIRytale of Software Citations”, which presents the journey of software citations through multiple workflows and the pitfalls of software citations in a narrative with original illustrations. The story features the journey of a scholar carrying tokens of gratitude through the Shiver Forest of Scholarly Writing, facing multiple dangers in his path.

description: Randomized Aggregatable Privacy-Preserving Ordinal Response, or RAPPOR, is a technology for crowdsourcing statistics from end-user client software, anonymously, with strong privacy guarantees. In short, RAPPORs allow the forest of client data to be studied, without permitting the possibility of looking at individual trees. By applying randomized response in a novel manner, RAPPOR provides the mechanisms for such collection as well as for efficient, high-utility analysis of the collected data. In particular, RAPPOR permits statistics to be collected on the population of client-side strings with strong privacy guarantees for each client, and without linkability of their reports. This paper describes and motivates RAPPOR, details its differential-privacy and utility guarantees, discusses its practical deployment and properties in the face of different attack models, and, finally, gives results of its application to both synthetic and real-world data.

description: We propose to use dynamical symmetries of the field equations, in order to classify the dark energy models in the context of scalar field (quintessence or phantom) FLRW cosmologies. Practically, symmetries provide a useful mathematical tool in physical problems since they can be used to simplify a given system of differential equations as well as to determine the integrability of the physical system. The requirement that the field equations admit dynamical symmetries results in two potentials one of which is the well known Unified Dark Matter (UDM) potential and another new potential. For each hyperbolic potential we obtain the corresponding analytic solution of the field equations. The proposed analysis suggests that the requirement of the contact symmetry appears to be very competitive to other independent tests used to probe the functional form of a given potential and thus the associated nature of dark energy. Finally, in order to test the viability of the above scalar field models we perform a joint likelihood analysis using some of the latest cosmological data.

description: In this work the $B\bar{B}^*/D\bar{D}^*$ system is studied in the Bethe-Salpeter approach with quasipotential approximation. In our calculation both direct and cross diagrams are included in the one-boson-exchange potential. The numerical results indicate the existence of a isoscalar bound state $D\bar{D}^*$ with $J^{PC}=1^{++}$, which may be related to the $X(3872)$. In the isovector sector, no bound state is produced from the interactions of $D\bar{D}^*$ and $B\bar{B}^*$, which suggests the molecular state explanations for $Z_b(10610)$ and $Z_c(3900)$ are excluded.

As a non-Newtonian viscosity we consider the Ladyzenskaya model with a non-linear velocity dependent stress tensor. The key idea is the multi-dimensional generalization of the well-known self-similar Ansatz, which was already used for non-compressible and compressible viscous flow studies. The geometrical interpretations of the trial function is also discussed. We compare our recent results to the former Newtonian ones.

Double-pole nature of $Λ(1405)$ studied with coupled-channel complex scaling method using complex-range Gaussian basis

description: The excited hyperon $Λ(1405)$ is the important building block for kaonic nuclei which are nuclear many-body system with anti-kaons. We have been investigating the $Λ(1405)$ resonance with the coupled-channel Complex Scaling Method (ccCSM) in which the $Λ(1405)$ is treated as a hadron-molecular state of a $\bar{K}N$-$πΣ$ coupled system. We use a $\bar{K}N$(-$πY$) potential based on the chiral SU(3) theory. In this article, we report the double-pole nature of the $Λ(1405)$, which is a characteristic property predicted by many studies with chiral SU(3)-based models. With the help of the complex-range Gaussian basis in ccCSM, we have found successfully another pole besides a pole near the $\bar{K}N$ threshold (called higher pole) which was found in our previous work with the real-range Gaussian basis. The new pole (called lower pole) is found far below $\bar{K}N$ threshold: $(M, -Γ/2)=(1395, -138)$ MeV when $f_π=110$ MeV. In spite of so broad width of the lower-pole state, the state is clearly identified with good separation from continuum states, since the oscillatory behavior of the continuum states is improved owing to the complex-range Gaussian basis. Analyzing the ccCSM wave function of the lower pole, we have revealed explicitly that the lower-pole state is dominated by the $πΣ$ component rather than the $\bar{K}N$ component. We have confirmed that the ccCSM wave function is correctly connected to the asymptotic form of the resonance wave function. We have estimated the meson-baryon mean distance for the lower-pole state as well as for the higher-pole state. In addition, we have investigated the origin of the appearance of the lower pole. The lower pole is confirmed to be generated by the energy dependence attributed to the chiral dynamics, by comparing the result of an energy-independent potential.

description: We study the Sunyaev-Zel'dovich (SZ) distortion of the cosmic microwave background radiation (CMBR) from extensive circumgalactic gas (CGM) in massive galactic halos. Recent observations have shown that galactic halos contain a large amount of X-ray emitting gas at the virial temperature, as well as a significant amount of warm OVI absorbing gas. We consider the SZ distortion from the hot gas in those galactic halos in which the gas cooling time is longer than the halo destruction time scale. We show that the SZ distortion signal from the hot gas in these galactic halos at redshifts $z\approx 1\hbox{--}8$ can be significant at small angular scales ($\ell\sim 10^4$), and dominate over the signal from galaxy clusters. The estimated SZ signal for most massive galaxies (halo mass $\ge 10^{12.5}$ M$_\odot$) is consistent with the marginal detection by {\it Planck} at these mass scales. We also consider the SZ effect from warm circumgalactic gas. The integrated Compton distortion from the warm OVI absorbing gas is estimated to be $y\sim 10^{-8}$, which could potentially be detected by experiments planned for the near future. Finally, we study the detectability of the SZ signal from circumgalactic gas in two types of surveys, a simple extension of the SPT survey and a more futuristic cosmic variance-limited survey. We find that these surveys can easily detect the kSZ signal from CGM. With the help of a Fisher Matrix analysis, we find that it will be possible for these surveys to constrain the gas fraction in CGM, after marginalizing over cosmological parameters, to $\le 33$\%, in case of no redshift evolution of the gas fraction.

6d-5d-4d reduction of BPS attractors in flat gauged supergravities

description: Via a series of Kaluza-Klein (KK) and Scherk-Schwarz (SS) compactifications we relate BPS attractors and their complete (in general non-BPS) flows to a Minkowski vacuum in gauged supergravities with vanishing scalar potential in 4, 5, and 6 dimensions. This way we can look at a class of extremal non-BPS black holes and strings from IIB string theory viewpoint, keeping 4 supercharges on the horizon. Our results imply the existence of a dual 2d N = (0,2) superconformal field theory (SCFT) that originates from a parent N=(4,4) theory living on a D1-D5 system. This is achieved starting from the BPS black string in 6d with an AdS_3xS^3 attractor and taking two different routes to arrive at a 1/2 BPS AdS_2xS^2 attractor of a non-BPS black hole in 4d N=2 flat gauged supergravity. The two inequivalent routes interchange the order of KK reduction on AdS_3 and SS reduction on S^3. We also find the commutator between the two operations after performing a duality transformation: on the level of the theory the result is the exchange of electric with magnetic gaugings; on the level of the solution we find a flip of the quartic invariant I_4 to -I_4.

description: We examine the nanoscale behavior of an equilibrium three-phase contact line in the presence of long-ranged intermolecular forces by employing a statistical mechanics of fluids approach, namely density functional theory (DFT) together with fundamental measure theory (FMT). This enables us to evaluate the predictive quality of effective Hamiltonian models in the vicinity of the contact line. In particular, we compare the results for mean field effective Hamiltonians with disjoining pressures defined through (I) the adsorption isotherm for a planar liquid film, and (II) the normal force balance at the contact line. We find that the height profile obtained using (I) shows good agreement with the adsorption film thickness of the DFT-FMT equilibrium density profile in terms of maximal curvature and the behavior at large film heights. In contrast, we observe that while the height profile obtained by using (II) satisfies basic sum rules, it shows little agreement with the adsorption film thickness of the DFT results. The results are verified for contact angles of 20, 40 and 60 degrees.

description: In this, paper we study the possibility of generation of electromagnetic waves in the magnetospheres of radio magnetars by means of the quasi-linear diffusion (QLD). Considering the magnetosphere composed of the so-called beam and the plasma components respectively, we argue that the frozen-in condition will inevitably lead to the generation of the unstable cyclotron modes. These modes, via the QLD, will in turn influence the particle distribution function, leading to certain values of the pitch angles, thus to an efficient synchrotron mechanism, producing radio photons. We show that for three known radio magnetars the QLD might be a realistic mechanism for producing photons in the radio band.

It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated luminosity of 0.14 $\mathrm{nb}^{-1}$ and 0.15 $\mathrm{nb}^{-1}$ in the muon and electron decay channels, respectively. The differential production yields and lepton charge asymmetry are each measured as a function of the average number of participating nucleons $< N_{\mathrm{part}} >$ and absolute pseudorapidity of the charged lepton. The results are compared to predictions based on next-to-leading-order QCD calculations. These measurements are, in principle, sensitive to possible nuclear modifications to the parton distribution functions and also provide information on scaling of $\textit{W}$ boson production in multi-nucleon systems.

description: We investigate the dynamics of a family of functional extensions of the (Eddington-inspired) Born-Infeld gravity theory, constructed with the inverse of the metric and the Ricci tensor. We provide a generic formal solution for the connection and an Einstein-like representation for the metric field equations of this family of theories. For particular cases we consider applications to the early-time cosmology and find that non-singular universes with a cosmic bounce are very generic and robust solutions.

description: We demonstrate the van der Waals epitaxy of the topological insulator compound Bi2Te3 on the ferromagnetic insulator Cr2Ge2Te6. The layers are oriented with (001) of Bi2Te3 parallel to (001) of Cr2Ge2Te6 and (110) of Bi2Te3 parallel to (100) of Cr2Ge2Te6. Cross-sectional transmission electron microscopy indicates the formation of a sharp interface. At low temperatures, bilayers consisting of Bi2Te3 on Cr2Ge2Te6 exhibit a large anomalous Hall effect (AHE). Tilted field studies of the AHE indicate that the easy axis lies along the c-axis of the heterostructure, consistent with magnetization measurements in bulk Cr2Ge2Te6. The 61 K Curie temperature of Cr2Ge2Te6 and the use of near-stoichiometric materials may lead to the development of spintronic devices based on the AHE.

description: If dark energy and dark matter interact via exchange of energy and momentum, then this may affect the galaxy power spectrum on large scales. When this happens, it may be degenerate with the signal from primordial non-Gaussianity via scale-dependent bias. We consider a class of interacting dark energy models and show that the matter overdensity is scale-dependent on large scales. We estimate the effective non-Gaussianity arising from the large-scale effects of interaction in the dark sector. The signal of dark sector interaction can be disentangled from a primordial non-Gaussian signal by measuring the power at two redshifts.

description: The legal personality of a legal entity is embodied in the activities of its management bodies, the purpose of which is to strive to achieve the results of business activities and meet other interests of the legal entity, its participants (founders). However, in the process of interaction between the management bodies of a legal entity, situations arise when the participants in such interaction pursue different or mutually exclusive goals, which is due to the polar desire to secure corporate interests, which leads to a corporate conflict.One of these is the construction of the legal liability of officials of the corporate governance body for the harm caused by their actions in the relevant area.In turn, fiduciary relations between a legal entity, its founders (shareholders) and officials of the relevant corporate governance body form a different legal model of interaction between them. Confidence in the integrity and goodwill of the party with whom the principal is in a relationship based on his trust does not imply that he expects irrational behavior of the attorney.Because the fiducia between participants of these relations creates higher risks of abuse, it is correct, in our opinion, to establish legal factors of not only reasonable compensation to the injured party, Theoretical aspects of civil liability of officers of body corporate management which is the institute of compensation of harm as such, but also to establish the prevention of abuse, other types of malevolent behavior increased the legal liability of officers of body corporate legal entity management by exception guilt as a condition of responsibility. In this method, the existing disparity in the legal capabilities of participants in the studied trust relationships is balanced, one of which is in a legally weak state.Thus, the principle of civil liability regardless of the fault of the delinquent becomes a reasonable balance in ensuring the interests of the legal entity and the implementation of the professional competence of the corporate governance body and its officials.

description: We give exact formulas for the right-handed analog of the CKM matrix in the minimal Left-Right symmetric theory, for the case when the Left-Right symmetry is generalized Parity as in the original version of the theory. We derive its explicit form and give a physical reason for the known and surprising fact that the right-handed mixing angles are close in value to the CKM ones, in spite of the Left-Right symmetry being badly broken in nature. We exemplify our results on the production of the right-handed charged gauge boson and the computation of the neutral K meson mass difference.

description: This thesis generates new understandings on the role of identity in ISIL’s recruitment and social media propaganda by examining how recruiters tailor propaganda to Australian Muslim men. Using Critical Discourse Analysis (CDA) and the author’s Hybrid Identity Framework (HIF), this thesis examines the ISIL-inspired social media activity of three deceased Australians. This thesis finds that ISIL propaganda communicates a central ideological narrative that followers utilize as a template for identity negotiation, expression, and communication. ISIL encourages prosumption of its propaganda in order to draw upon their followers social and cultural capital to radicalize and recruit prospective members.
Spin evolution of Earth-sized exoplanets, including atmospheric tides and core-mantle friction

description: Planets with masses between 0.1 - 10 M_earth are believed to host dense atmospheres. These atmospheres can play an important role on the planet's spin evolution, since thermal atmospheric tides, driven by the host star, may counterbalance gravitational tides. In this work we study the long-term spin evolution of Earth-sized exoplanets. We generalize previous works by including the effect of eccentric orbits and obliquity. We show that under the effect of tides and core-mantle friction, the obliquity of the planets evolve either to 0 or 180 degrees. The rotation of these planets is also expected to evolve into a very restricted number of equilibrium configurations. In general, none of this equilibria is synchronous with the orbital mean motion. The role of thermal atmospheric tides becomes more important for Earth-sized planets in the habitable zones of their systems, so they cannot be neglected when we search for their potential habitability.

description: The effects of lithium absorption on the crystal structure and electronic properties of IrSi3, a binary silicide with a noncentrosymmetric crystal structure, were studied. X-ray and neutron diffraction experiments revealed that hexagonal IrSi3 (space group P6_3mc) transforms into trigonal Li2IrSi3 (space group P31c) upon lithium absorption. The structure of Li2IrSi3 is found to consist of a planar kagome network of silicon atoms with Li and Ir spaced at unequal distances between the kagome layers, resulting in a polar structure along the c-axis. Li2IrSi3 exhibited type-II superconductivity with a transition temperature Tc of 3.8 K, displaying a structure type that no previous superconductors have been reported to have.

description: Achieving individual qubit readout is a major challenge in the development of scalable superconducting quantum processors. We have implemented the multiplexed readout of a four transmon qubit circuit using non-linear resonators operated as Josephson bifurcation amplifiers. We demonstrate the simultaneous measurement of Rabi oscillations of the four transmons. We find that multiplexed Josephson bifurcation is a high-fidelity readout method, the scalability of which is not limited by the need of a large bandwidth nearly quantum-limited amplifier as is the case with linear readout resonators.

description: We discuss the Noether Symmetry Approach in the framework of Gauss-Bonnet cosmology showing that the functional form of the $F(R, {\cal G})$ function, where $R$ is the Ricci scalar and ${\cal G}$ is the Gauss-Bonnet topological invariant, can be determined by the presence of symmetries. Besides, the method allows to find out exact solutions due to the reduction of cosmological dynamical system and the presence of conserved quantities. Some specific cosmological models are worked out
