description: In recent years it has been claimed that the length of stellar activity cycles is determined by the stellar rotation rate. It is observed that the cycle period increases with rotation period along the so-called active and inactive sequences. In this picture the Sun occupies a solitary position in between the two sequences. Our goal is to measure cyclic variations of the stellar light curve amplitude and the rotation period using four years of Kepler data. Periodic changes of the light curve amplitude or the stellar rotation period are associated with an underlying activity cycle. Using the McQuillan et al. 2014 sample we compute the rotation period and the variability amplitude for each Kepler quarter and search for periodic variations of both time series. To test for periodicity in each stellar time series we consider Lomb-Scargle periodograms and use a selection based on a False Alarm Probability (FAP). We detect amplitude periodicities in 3203 stars between 0.5-6 years covering rotation periods between 1-40 days. Given our sample size of 23,601 stars and our selection criteria that the FAP is less than 5%, this number is almost three times higher than that expected from pure noise. We do not detect periodicities in the rotation period beyond those expected from noise. Our measurements reveal that the cycle period shows a weak dependence on rotation rate, slightly increasing for longer rotation period. We further show that the shape of the variability deviates from a pure sine curve, consistent with observations of the solar cycle. Our measurements do not support the existence of distinct sequences in the P_rot-P_cyc plane, although there is some evidence for the inactive sequence for rotation periods between 5-25 days. Unfortunately, the total observing time is too short to draw sound conclusions on activity cycles with similar length as the solar cycle.

Towards time-aware context-aware deep trust prediction in online social networks

description: Trust can be defined as a measure to determine which source of information is reliable and with whom we should share or from whom we should accept information. There are several applications for trust in Online Social Networks (OSNs), including social spammer detection, fake news detection, retweet behaviour detection and recommender systems. Trust prediction is the process of predicting a new trust relation between two users who are not currently connected. In applications of trust, trust relations among users need to be predicted. This process faces many challenges, such as the sparsity of user-specified trust relations, the context-awareness of trust and changes in trust values over time. In this dissertation, we analyse the state-of-the-art in pair-wise trust prediction models in OSNs. We discuss three main challenges in this domain and present novel trust prediction approaches to address them. We first focus on proposing a low-rank representation of users that incorporates users' personality traits as additional information. Then, we propose a set of context-aware trust prediction models. Finally, by considering the time-dependency of trust relations, we propose a dynamic deep trust prediction approach. We design and implement five pair-wise trust prediction approaches and evaluate them with real-world datasets collected from OSNs. The experimental results demonstrate the effectiveness of our approaches compared to other state-of-the-art pair-wise trust prediction models.

description: We report on a versatile mini ultra-high vacuum (UHV) chamber which is designed to be used on the MAgnetic Reflectometer with high Incident Angle of the Jülich Centre for Neutron Science at Heinz Maier-Leibnitz Zentrum in Garching, Germany. Samples are prepared in the adjacent thin film laboratory by molecular beam epitaxy and moved into the compact chamber for transfer without exposure to ambient air. The chamber is based on DN 40 CF flanges and equipped with sapphire view ports, a small getter pump, and a wobble stick, which serves also as sample holder. Here, we present polarized neutron reflectivity measurements which have been performed on Co thin films at room temperature in UHV and in ambient air in a magnetic field of 200 mT and in the Q-range of 0.18 Å$^{-1}$. The results confirm that the Co film is not contaminated during the polarized neutron reflectivity measurement. Herewith it is demonstrated that the mini UHV transport chamber also works as a measurement chamber which opens new possibilities for polarized neutron measurements under UHV conditions.

description: It is argued that the hollowness effect (depletion in the absorptive part of the scattering cross section at small values of the impact parameter) in the proton-proton scattering at the the LHC energies finds its origin in the quantum nature of the process, resulting in large values of the real part of the eikonal phase. The effect cannot be reconciled with an incoherent superposition of the absorption from the proton constituents, thus suggests the change of this basic paradigm of high-energy scattering.

description: A triple-GEM detector with two-dimensional readout is developed. The detector provides high position resolution for powder diffraction experiments at synchrotron radiation. Spatial resolution of the detector is measured in the lab using a 55Fe X-ray source. A resolution of about 110 um FWHM is achieved. The energy resolution is better than 27% for 5.9 keV X-rays. The detector's validity under illumination of photons in particular energy range is verified using a Cu X-ray tube. Imaging of the head of a wire stripper with X-ray tube demonstrates its imaging ability. A diffraction imaging experiment using the sample of powder SiO2 is successfully carried out at 1W2B laboratory of Beijing Synchrotron Radiation Facility (BSRF). Different diffraction rings are clearly seen under various X-ray energies.

Knockout mutations of the LuxR regulator PFL_3627 and the sRNA phrS causes pleiotropic effects on the biocontrol bacterium Pseudomonas protegens Pf-5

description: The Pseudomonas protegens Pf-5 (previously known as P.fluorescens Pf-5) has shown potential as a biological control agent against plant pathogenic bacteria, fungi and nematodes. The production of anti-pathogen compounds and rhizosphere colonisation are two of the key traits that determine its biocontrol competency. Genetic and biochemical studies of secondary metabolite biosynthesis combined with analysis of the genome sequence have clarified many aspects of the production of anti-pathogen compounds in Pf-5. However, there is only very limited data on the molecular factors important for rhizosphere colonisation. Successful rhizosphere colonisation is likely influenced by two features: motility and biofilm formation. In many bacteria, motility and biofilm are both regulated by quorum sensing (QS) and small RNAs (sRNA). This study focuses on a LuxR solo regulator PFL_3627 involved in QS, and a sRNA phrS. Gene knockouts of both of these genes reveal they have pleiotropic effects on both biofilm formation and motility. A microarray analysis of a PFL_3627 mutant revealed a large number of genes that are up- or down-regulated by this regulator. Generally, canonical QS regulation by LuxR is mediated by the exogenous or endogenous QS signalling molecules N-acyl-homoserine-lactone (AHL). The Pf-5 genome does not encode a LuxI homolog for AHL biosynthesis, and consistent with this no endogenous AHL production was detected using biosensor strains. An assay of exogenous addition of short or long chain AHLs suggested that the LuxR regulator PFL_3627 is not involved in sensing AHLs. Thus PFL_3627 is presumably involved in the sensing of an as yet unknown molecule, possibly of plant origin.
Spin-orbit splittings of neutron states in $N = 20$ isotones from covariant density functionals and their extensions

description: Spin-orbit splitting is an essential ingredient for our understanding of the shell structure in nuclei. One of the most important advantages of relativistic mean-field (RMF) models in nuclear physics is the fact that the large spin-orbit (SO) potential emerges automatically from the inclusion of Lorentz-scalar and -vector potentials in the Dirac equation. It is therefore of great importance to compare the results of such models with experimental data. We investigate the size of $2p$ and $1f$ splittings for the isotone chain $^{40}$Ca, $^{38}$Ar, $^{36}$S, and $^{34}$Si in the framework of various relativistic and nonrelativistic density functionals. They are compared with the results of nonrelativistic models and with recent experimental data.

Multidimensional poverty and migrant households: a case study of Vietnam
Creators: name: Quang, Anh Thu Pham
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This project utilises the ‘Fuzzy Set Approach” to measure multidimensional poverty of migrant households, especially families left behind, in Vietnam.. Until now the government of Vietnam has applied income and expenditure approaches to identify poor households, these measures that do not fully capture the multidimensional nature of poverty, which are expressed in both income (expenditure) and non-income indicators. Although there have been a number of studies on rural-urban migration, most of them have investigated the determinants and effects of migration on destination areas instead of sending areas of migration. This project, therefore, aims to study the effects of migration on sending areas and thus to contribute to scholarship on migration and ultimately help Vietnamese policy makers to determine suitable strategies to effectively develop poverty alleviation programs and improve the welfare of migrants.

Employing a rigid holding geometry that is first-order insensitive to the squeezing force and a cavity geometry that improves the thermal noise limit at room temperature, we observe a laser phase noise that is nearly thermal noise limited for three frequency decades (1 Hz to 1 kHz offset) and supports 10 GHz generation with phase noise near -100 dBc/Hz at 1 Hz offset and 600 Hz. The fractional frequency stability reaches $2\times10^{-15}$ at 0.1 s of averaging.

description: The present study explored the cooperative effect of both alanine (Ala) and gentamicin (Gent) on metabolic mechanisms by which exogenous Ala potentiates Gent to kill antibiotic-resistant Vibrio alginolyticus. To test this, GC-MS-based metabolomics was used to characterize Ala-, Gent- and both-induced metabolic profiles, identifying nitric oxide (NO) production pathway as the most key clue to understand metabolic mechanisms. Gent, Ala and both led to low, lower and lowest activity of total nitric oxide synthase (tNOS) and level of NO, respectively. NOS promoter L-arginine and inhibitor NG-Monomethyl-L-arginine inhibited and promoted the killing, respectively, with the elevation and decrease of NOS activity and NO level. The present study further showed that CysJ is the enzyme-producing NO in V. alginolyticus. These results indicate that the cooperative effect of Ala and Gent causes the lowest NO, which plays a key role in Ala-potentiated Gent-mediated killing.
Dynamics of binary Bose-Einstein condensate via Ehrenfest like equations: Appearance of almost shape invariant states

Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We derive Ehrenfest like equations for the coupled Gross Pitaevskii equations (CGPE) which describe the dynamics of the binary Bose-Einstein condensate (BBEC) both in the free particle regime and in the regime where condensate is well trapped. Instead of traditional variational technique, we propose a new Ehrenfest based approach to explore so far unrevealed dynamics for CGPE and illustrate the possibility of almost shape invariant states in both the regimes. In absence of trapping potential, when all the interactions present in the system are attractive, it is possible for an initially mixed Gaussian state to propagate with almost no change in width if the proper initial condition is satisfied. Even for repulsive intra-atomic and attractive inter-atomic interaction ($g_{αβ}$) one can tune $|g_{αβ}|$ such that the width of the propagating wave packet remains bounded within almost about $10\%$. We also discuss the dynamics of the initially phase separated condensate and have shown the breakdown of Gaussian nature of the wave packets due to collisions. However, when BEC is trapped in simple harmonic oscillator(SHO) potential, for $g_{αβ}>0$, it is possible for an initially overlapping state to retain its initial shape if $g_{αβ}$ is less than a critical value ($g_{αβ}^c$). If $g_{αβ}$ exceeds $g_{αβ}^c$, an overlapping state can become phase separated while keeping its shape unchanged.

description: We present a comprehensive study of how superconducting fluctuations in the normal state contribute to the conductivity tensor in a thin (119 $Å$) film of NbN. It is shown how these fluctuations drive a sign change in the Hall coefficient $R_\mathrm{H}$ for low magnetic fields near the superconducting transition. The scaling behaviours as a function of distance to the transition $ε=\ln(T/T_\mathrm{c})$ of the longitudinal ($σ_\mathrm{xx}$) and transverse ($σ_\mathrm{xy}$) conductivity is found to be consistent with Gaussian fluctuation theory. Moreover, excellent quantitative agreement between theory and experiment is obtained without any adjustable parameters. Our experimental results thus provide a case study of the conductivity tensor originating from short-lived Cooper pairs.

Such a collection is assumed to represent a dark matter inhomogeneity which reaches a stationary state determined by the virialization of the system. We describe some features of the stationary states and, by using several halo models, obtain distinctive signatures for the evolution of the inhomogeneities in each of the models.

description: We present an approach which allows the consistent treatment of bound states in the context of the dc conductivity in dense partially ionized noble gas plasmas. Besides electron-ion and electron-electron collisions, further collision mechanisms owing to neutral constituents are taken into account. Especially at low temperatures $T\approx 1 {\rm eV}$, electron-atom collisions give a substantial contribution to the relevant correlation functions. We suggest an optical potential for the description of the electron-atom scattering which is applicable for all noble gases. The electron-atom momentum-transfer cross section is in agreement with experimental scattering data. In addition the influence of the medium is analysed, the optical potential is advanced including screening effects. The position of the Ramsauer minimum is influenced by the plasma. Alternative approaches for the electron-atom potential are discussed. Calculations of the electrical conductivity are compared with experimental data.

description: Electron-phonon interaction in superconducting transition metals (Ta, Mo, W) is investigated by the method of point-contact spectroscopy. The spectra obtained are compared with model densities of the phonon states $F(ω)$ computed from experiments on neutron scattering, and with the tunnel electron-phonon interaction function $g(ω)$ for Ta. Close agreement between the appropriate spectra is obtained for Ta and Mo, while a significant discrepancy is observed for W, which is the appearance of a blurred maximum instead of the two expected separated peaks on the point-contact spectra. The absolute intensities of a number of point-contact spectra $G(eV)$ and electron-phonon coupling constants $λ$ are calculated. For all three metals the values obtained turned out to be considerably below those expected. The possible reasons for this disagreement are discussed.

Thinking In semicircular terms?: cooperation practices in the Polish-German and Danish-German borderland
Creators: name: Kaden, Ulrike
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: State borders are powerful markers of difference. Despite changes in socio-spatial organisation associated with contemporary globalisation processes, there are no indications that borders have lost their significance. Quite on the contrary, border s continue to have an organising and controlling function across and between societies. This is most evident in the case of the European integration project, where border reorganisation has come to inform imaginaries of Europe and European space. Beyond the rhetoric of a 'borderless Europe', the process of Europeanisation illustrates particularly well how practices of de-and re-bordering must be seen in context. Yet the evolution of the Schengen area and the abolition of stationary border controls tell little about the persistency of socio-cultural boundaries across inner-European borderlands. This dissertation project aims to develop a better understanding of the character of inner - European borders in the face of the Schengen Agreement and, more specifically, the role of cross-border practices in reproducing or challenging exclusive ideas of citizenship and space. By studying cooperation practices amongst 'borderlanders', the dissertation focusses on a particular variant of cross - border practices intended to dismantle restrictive socio-cultural boundaries and geographical imaginaries. The question of how cooperation practices are related to the reproduction of inner-European borders provides a significant means to analyse how and to what extent these borderlines represent latent and potential resources for political narratives of exclusion. This perspective is becoming increasingly important in the face of the EU's handling of migration and refugee flows, including temporary reintroductions of stationary border controls. This dissertation is grounded in a qualitative, reconstructive investigation of cooperation practices across the Polish-German and Danish-German borderland, focussing on the fields of urban & regional development, education, and the cultural sector.

description: DksA with (p)ppGpp regulates a wide range of gene transcriptions during the stringent response. The aim of this study was to identify a DksA ortholog in Acinetobacter baumannii and clarify the roles of DksA in bacterial physiology and virulence. The ∆dksA mutant and its complemented strains were constructed using A. baumannii ATCC 17978. The AlS_0248 in A. baumannii ATCC 17978 was identified to dksA using sequence homology, protein structure prediction, and gene expression patterns under different culture conditions. The ∆dksA mutant strain showed a filamentous morphology compared with the wild-type (WT) strain. Bacterial growth was decreased in the ∆dksA mutant strain under static conditions. Surface motility was decreased in the ∆dksA mutant strain compared with the WT strain. In contrast, biofilm formation was increased and biofilm-associated genes, such as bfmR/S and csuC/D/E, were upregulated in the ∆dksA mutant strain. The ∆dksA mutant strain produced less autoinducers than the WT strain. The expression of abaI and abaR was significantly decreased in the ∆dksA mutant strain. Furthermore, the ∆dksA mutant strain showed less bacterial burden and milder histopathological changes in the lungs of mice than the WT strain. Mice survival was also significantly different between the ∆dksA mutant and WT strains. Conclusively, DksA is directly or indirectly involved in regulating a wide range of genes associated with bacterial physiology and virulence, which contributes to the pathogenesis of A. baumannii. Thus, DksA is a potential anti-virulence target for A. baumannii infection.

description: By converting energy into mechanical work, engines play a central role in most biological and technological processes. In particular, within the current trend towards the development of nanoscience and nanotechnology, microscopic engines have been attracting an ever-increasing interest. On the one hand, there has been a quest to understand how biological molecular motors work. On the other hand, several approaches have been proposed to realize artificial microscopic engines, which have been powered by the transfer of light momentum, by external magnetic fields, by in situ chemical reactions, or by the energy flow between hot and cold heat reservoirs, in scaled-down versions of macroscopic heat engines. Here, we experimentally demonstrate a microscopic engine powered by the local reversible demixing of a critical mixture. We show that, when an absorbing microsphere is optically trapped by a focused laser beam in a sub-critical mixture, it is set into rotation around the optical axis of the beam because of the emergence of diffusiophoretic propulsion; this behavior can be controlled by adjusting the optical power, the temperature, and the criticality of the mixture. Given its simplicity, this microscopic engine provides a powerful tool to power micro- and nanodevices. Furthermore, since many biological systems are tuned near criticality, this mechanism might already be at work within living organisms, for example in proteins and in cellular membranes.

description: We present an updated calculation of the uncertainties on the atmospheric muon-neutrino flux arising from cosmic-ray primaries. For the first time, we include recent measurements of the cosmic-ray primaries collected since 2005. We apply a statistical technique that allows the determination of correlations between the parameters of the GSHL primary-flux parametrisation and the incorporation of these correlations into the uncertainty on the muon-neutrino flux. We obtain an uncertainty related to the primary cosmic rays of around $(5\text{--}15)\%$, depending on energy, which is about a factor of two smaller than the previously determined uncertainty. The hadron production uncertainty is added in quadrature to obtain the total uncertainty on the neutrino flux, which is reduced by $\approx 5\%$. To take into account an unexpected hardening of the spectrum of primaries above energies of $100$ $\text{GeV}$ observed in recent measurements, we propose an alternative parametrisation and discuss its impact on the neutrino flux uncertainties.

description: "In this dissertation I specified a model proposing that managerial cognitive style could result in knowledge asymmetries which under environmental dynamism lead to a different emphasis placed on business model innovation which could be a determinant of firms' differential growth in an industry. This theory synthesizes insights from different but interrelated bodies of research including Edith Penrose's theory of the growth of the firm, managerial dynamic capabilities and the knowledge-based view, business model of the firm and strategic cognition. I further tested the proposed model using a mixed-methods design based on the data from CEOs of small manufacturing firms in Australia. In the quantitative phase a hybrid survey consisting of postal and online modes was conducted and data from 299 firms was analyzed by employing a two-step structural equation modeling approach. 13 hypotheses and 11 control variables were assessed. In the qualitative phase semi-structured in-depth interviews with 5 CEOs were conducted and analyzed using content and thematic analytic methods with Nvivo. The results of this qualitative phase were used to corroborate and cross-validate the results of the statistical analysis. Furthermore, this exploratory analysis generated a number of additional interesting themes. The results of these analyses supported my key theoretical expectations while offering some new insights into the underlying mechanisms of the growth of the firm.'' -- Abstract.

description: In Quito, the model of the Andean colonial city - based on the spatial concretion of a hierarchical and exclusive social structure - entered in crisis in the 80s of the 20th century. In this period, previously marginalized afro-descendant and indigenous groups start to participate in the processes of land occupation and in construction of new peripheral neighborhoods. Using stories of families from the northwest of Quito, this article explore the struggles for land and education, two elements that subaltern groups have claimed to be include, claiming their right to the city.

description: Key messages

Given co-existing societal challenges and crises in human, environmental, economic, and political domains, sustainability transitions are the only way to drive the world towards a better future for all.

Sustainable Human Development with its five pillars – productivity, equity, environmental sustainability, participation & empowerment, and human security – should be the cornerstone of future European policy frameworks.

Global and European policies should embrace an integrated vision of Sustainable Human Development to holistically fulfil societal needs while respecting planetary boundaries through collaborative governance.

The transition towards Sustainable Human Development must be dynamic and centred on collective human action, requiring resources, actions, and capacities to adapt the path to changes within multi-level and multi-stakeholder processes. 

European policies must enable appropriate governance mechanisms, capital investments towards Sustainable Human Development, the adoption of suitable measurement systems, transformative Research & Innovation policy, and the promotion of active citizenship.

description: Supersonic beams of hydrogen atoms, prepared selectively in Rydberg-Stark states of principal quantum number $n$ in the range between 25 and 35, have been deflected by 90$^\circ$, decelerated and loaded into off-axis electric traps at initial densities of $\approx 10^6$ atoms/cm$^{-3}$ and translational temperatures of 150 mK. The ability to confine the atoms spatially was exploited to study their decay by radiative and collisional processes. The evolution of the population of trapped atoms was measured for several milliseconds in dependence of the principal quantum number of the initially prepared states, the initial Rydberg-atom density in the trap, and the temperature of the environment of the trap, which could be varied between 7.5 K and 300 K using a cryorefrigerator. At room temperature, the population of trapped Rydberg atoms was found to decay faster than expected on the basis of their natural lifetimes, primarily because of absorption and emission stimulated by the thermal radiation field. At the lowest temperatures investigated experimentally, the decay was found to be multiexponential, with an initial rate scaling as $n^{-4}$ and corresponding closely to the natural lifetimes of the initially prepared Rydberg-Stark states. The decay rate was found to continually decrease over time and to reach an almost $n$-independent rate of more than (1 ms)$^{-1}$ after 3 ms. To analyze the experimentally observed decay of the populations of trapped atoms, numerical simulations were performed which included all radiative processes, i.e., spontaneous emission as well as absorption and emission stimulated by the thermal radiation. These simulations, however, systematically underestimated the population of trapped atoms observed after several milliseconds by almost two orders of magnitude, although they reliably predicted the decay rates of the remaining atoms in the trap.
