description: The development of detectors that provide high resolution in four dimensions has attracted wide-spread interest in the scientific community for several applications in high-energy physics, nuclear physics, medical imaging, mass spectroscopy as well as quantum information. In addition to high time resolution and thanks to the AC-coupling of the electrodes, LGAD silicon sensors can provide high resolution in the measurement of spatial coordinates of an incident minimum ionizing particle. Such AC-coupled LGADs, also known as AC-LGADs, are therefore considered as candidates for future detectors to provide 4-dimensional measurements in a single sensing device with 100$\%$ fill factor. This article presents the first characterization of an AC-LGAD sensor with a proton beam of 120 GeV momentum at Fermilab. The sensor consists of strips with 80 $μ$m width, fabricated at Brookhaven National Laboratory. The signal properties, efficiency, spatial, and time resolution are presented. The experimental results show that the time resolution of such an AC-LGAD is compatible to standard LGADs with similar gain, and that AC-LGADs can be segmented with fine pitches as standard strip or pixel detectors.

Experimental evidence of shock mitigation in a Hertzian tapered chain

description: We present an experimental study of the mechanical impulse propagation through a horizontal alignment of elastic spheres of progressively decreasing diameter $ϕ_n$, namely a tapered chain. Experimentally, the diameters of spheres which interact via the Hertz potential are selected to keep as close as possible to an exponential decrease, $ϕ_{n+1}=(1-q)ϕ_n$, where the experimental tapering factor is either $q_1\simeq5.60$~% or $q_2\simeq8.27$~%. In agreement with recent numerical results, an impulse initiated in a monodisperse chain (a chain of identical beads) propagates without shape changes, and progressively transfer its energy and momentum to a propagating tail when it further travels in a tapered chain. As a result, the front pulse of this wave decreases in amplitude and accelerates. Both effects are satisfactorily described by the hard spheres approximation, and basically, the shock mitigation is due to partial transmissions, from one bead to the next, of momentum and energy of the front pulse. In addition when small dissipation is included, a better agreement with experiments is found. A close analysis of the loading part of the experimental pulses demonstrates that the front wave adopts itself a self similar solution as it propagates in the tapered chain. Finally, our results corroborate the capability of these chains to thermalize propagating impulses and thereby act as shock absorbing devices.

description: Automatic Service Composition is a research direction aimed at facilitating the usage of atomic web services. Particularly, the goal is to build workflows of services that solve specific queries, which cannot be resolved by any single service from a known repository. Each of these services is described independently by their providers that can have no interaction with each other, therefore some common standards have been developed, such as WSDL, BPEL, OWL-S. Our proposal is to use such standards together with JSON-LD to model a next level of semantics, mainly based on binary relations between parameters of services. Services relate to a public ontology to describe their functionality. Binary relations can be specified between input and/or output parameters in service definition. The ontology includes some relations and inference rules that help to deduce new relations between parameters of services. To our knowledge, it is for the first time that parameters are matched not only based on their type, but on a more meaningful semantic context considering such type of relations. This enables the automation of a large part of the reasoning that a human person would do when manually building a composition. Moreover, the proposed model and the composition algorithm can work with multiple objects of the same type, a fundamental feature that was not possible before. We believe that the poor model expressiveness is what is keeping service composition from reaching large-scale application in practice.

Picture Invariance in Quantum Optics

Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We clarify the controversy over the coherent-state (CS) versus the number-state (NS) pictures in quantum optics. The NS picture is equivalent to the CS picture, as long as the phases $ϕ$ in the laser fields are randomly distributed, as Mølmer argues [\pra {\bf 55}, 3195 (1997)]. However, the claim by Rudolph and Sanders [Phys. Rev. Lett. {\bf 87}, 077903 (2001)] has a few gaps. First, they make an assumption that is not necessarily true in the calculation of a density operator involved with a two-mode squeezed state. We show that there exists entanglement in the density operator without defying the assumption that phases are randomly distributed. Moreover, using a concept of picture-invariance, we argue that it is not that criteria for quantum teleportation are not satisfied. We discuss an analogy between the controversy on the CS versus NS pictures to that on the heliocentric versus geocentric pictures.

description: We present the first search for gravitational waves from the coalescence of stellar mass and sub-solar mass black holes with masses between $20 - 100~\mathrm{M}_{\odot}$ and $0.01 - 1~\mathrm{M}_{\odot}~($10 - 10^3$~\mathrm{M}_{J})$, respectively. The observation of a single sub-solar mass black hole would establish the existence of primordial black holes and a possible component of dark matter. We search the $\sim 164$ days of public LIGO data from 2015-2017 when LIGO-Hanford and LIGO-Livingston were simultaneously observing. We find no significant candidate gravitational-wave signals. Using this non-detection, we place a $90\%$ upper limit on the rate of $30-0.01~\mathrm{M}_{\odot}$ and $30-0.1~\mathrm{M}_{\odot}$ mergers at $<1.2\times10^{6}$ and $<1.6\times10^{4} ~\mathrm{Gpc}^{-3} \mathrm{yr}^{-1}$, respectively. If we consider binary formation through direct gravitational-wave braking, this kind of merger would be exceedingly rare if only the lighter black hole were primordial in origin ($<10^{-4}~\mathrm{Gpc}^{-3}\mathrm{yr}^{-1}$). If both black holes are primordial in origin, we constrain the contribution of $1 (0.1)~\mathrm{M}_{\odot}$ black holes to dark matter to $< 0.3 (3)\%$.

THE IMPACT OF TOBACCO MARKETING AND PRICING POLICY REFORMS ON INCOME INEQUALITY AMONGST GROWERS IN MALAWI: WHAT LESSONS CAN BE LEARNT FROM THE AUSTRALIAN EXPERIENCES?

description: Three key questions are addressed in this paper: (1) Have Malawi’s tobacco policy reforms led to improvements in the absolute prices that smallholders get? (2) How do the prices that smallholders receive compare with what the rich estate owners get? (3) Are there any lessons that Malawi can learn from the Australian experiences? Results from three tests, namely the empirical fluctuation process (efp) test, Poe, et al. (1994) convolutions test and Kolmogorov-Smirnov (KS) test indicate that overtime tobacco policy reforms have indeed led to some improvements in both absolute and relative prices that smallholder farmers receive. However, when compared with Victoria in 2006, Malawi’s tobacco land use is nearly 256 times more than Victoria and engages more farmers but gets far less farm gate value from tobacco. Adoption of modern farming technologies, specialization and value adding at the domestic scene can be appropriate lessons for Malawi. The closure of the Victorian tobacco industry in 2006 suggests that relying on tobacco as the only tool for Malawi’s economic growth and poverty reduction may not be sustainable in the long run. There is need to diversify to other crops such as cotton, pulses, cassava, and bananas.

description: A skyrmion state in a non-centrosymmetric helimagnet displays topologically protected spin textures with profound technological implications for high density information storage, ultrafast spintronics, and effective microwave devices. Usually, its equilibrium state in a bulk helimagnet occurs only over a very restricted magnetic-field--temperature phase space and often in the low temperature region near the magnetic transition temperature Tc. We have expanded and enhanced the skyrmion phase region from the small range of 55-58.5 K to 5-300 K in single-crystalline Cu2OSeO3 by pressures up to 42.1 GPa through a series of phase transitions from the cubic P2(_1)3, through orthorhombic P2(_1)2(_1)2(_1) and monoclinic P2(_1), and finally to the triclinic P1 phase, using our newly developed ultrasensitive high-pressure magnetization technique. The results are in agreement with our Ginzburg-Landau free energy analyses, showing that pressures tend to stabilize the skyrmion states and at higher temperatures. The observations also indicate that the skyrmion state can be achieved at higher temperatures in various crystal symmetries, suggesting the insensitivity of skyrmions to the underlying crystal lattices and thus the possible more ubiquitous presence of skyrmions in helimagnets.

Elisabeth Lutyens’s music drama The numbered : a critical-analytical study
Creators: name: Parsons, Laurel
Publisher: name: University of British Columbia
Year: 2009

description: Composer Elisabeth Lutyens (1906-83) was one of the outstanding pioneers of musical modernism in Britain, and is credited with producing the first British serial composition (the 1939 Chamber Concerto, Op. 8, No. 1). Although Lutyens's music was widely performed and recorded by major orchestras, instrumentalists and conductors in the 1960's and 1970's, her work has yet to receive the scholarly attention it deserves. This dissertation represents the first detailed study of her magnum opus, the music drama The Numbered (1967). Based on Nobel laureate Elias Canetti's 1953 play Die Befristeten, The Numbered explores how the consciousness of death affects human behaviour. The opera is set in a fictitious society whose members are allotted lifespans by the State, and named according to the number of years they will live. The main character Fifty suspects, and eventually proves to the public, that the State's supposed power over death is a hoax. Political revolution ensues, but by revealing to the people that death can come at any time, Fifty has reintroduced into society the fear, violence, murder and madness that the system had successfully controlled. Chapter 1 provides an introduction to Lutyens's career as well as the pre- and post-compositional history of the opera. Chapter 2 is devoted to the origins and structure of the libretto, including a discussion of Canetti's dramatic theories. Chapters 3 through 10 focus analytically, theoretically and critically on aspects of Lutyens's compositional technique in the opera: melodic and vocal characterization; Lutyens's use of, and varying adherence to, serial methods; temporal organization; and motivic structure. The purpose of the critical analysis is twofold: first, to illuminate the interaction of musical and dramatic elements in a compelling work of art that has yet to be published or publicly performed; and second, to introduce the reader to characteristic features of Elisabeth Lutyens's musical language.

description: The Type II-P supernova 2004dj in the nearby galaxy NGC 2403 occurred at a position coincident with object 96 in the list of luminous stars and clusters in this galaxy published by Sandage in 1984. The coincidence is established definitively through astrometric registration of our ground-based archival images of NGC 2403 with our recent images showing the SN. The archival images show that Sandage 96 is slightly resolved from the ground. Pre-outburst blue spectrograms obtained by Humphreys and Aaronson reveal that Sandage 96 has a composite spectrum, dominated in the blue region by A- and B-type stars, while infrared photometry shows that Sandage 96 also contains red supergiants. These results demonstrate that Sandage 96 is a young compact cluster. We have studied the stellar population of Sandage 96, using published photometric measurements combined with a chi-square-fitting code. We derive a cluster age of 13.6 Ma, a reddening of E(4405-5495)=0.172, and a total stellar mass of 24 000 M_Sun. For this cluster age, the SN progenitor had a main-sequence mass of 15 M_Sun. Post-outburst photometry of Sandage 96 may establish whether the progenitor was a red or blue supergiant.

description: Large magnetic structures are launched away from the Sun during solar eruptions. They are observed as (interplanetary) coronal mass ejections (ICMEs or CMEs) with coronal and heliospheric imagers. A fraction of them are observed insitu as magnetic clouds (MCs). Fitting these structures properly with a model requires a better understanding of their evolution. In situ measurements are done locally when the spacecraft trajectory crosses the magnetic configuration. These observations are taken for different elements of plasma and at different times, and are therefore biased by the expansion of the magnetic configuration. This aging effect leads to stronger magnetic fields measured at the front than at the rear of MCs, an asymmetry often present in MC data. However, can the observed asymmetry be explained quantitatively only from the expansion? Based on self-similar expansion, we derive a method to estimate the expansion rate from observed plasma velocity. We next correct for the aging effect both the observed magnetic field and the spatial coordinate along the spacecraft trajectory. This provides corrected data as if the MC internal structure was observed at the same time. We apply the method to 90 best observed MCs near Earth (1995-2012). The aging effect is the main source of the observed magnetic asymmetry only for 28\% of MCs. After correcting the aging effect, the asymmetry is almost symmetrically distributed between MCs with a stronger magnetic field at the front and those at the rear of MCs. The proposed method can efficiently remove the aging bias within insitu data of MCs, and more generally of ICMEs. This allows one to analyse the data with a spatial coordinate, such as in models or remote sensing observations.

description: With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers and landholders in rural Australia have increased opportunities to participate in the market. This includes the adoption of land-use change to sequester additional carbon in exchange for carbon credits and the production of a renewable energy source (biofuels). However, these land-use changes compete with existing farm enterprises and may contain significant transaction costs. Therefore it is necessary for the institutional arrangements to provide adequate incentives for landholders to adopt these land-use changes. This paper examines the potential supply of these land-use changes for climate mitigation from landholders in a northern NSW catchment. These results will allow further investigation of how incentive structures and policy instruments may be developed to increase the supply of these goods from landholders.

description: Hysteresis is studied in a disordered Ising model in which diffusion of antiferromagnetic bonds is allowed in addition to spin flips. Saturation behavior changes to a figure-eight loop when diffusion is introduced. The upper and lower fields delimiting the figure-eight are determined by the Hamiltonian, while its surface and the crossing point depend on the temperature and details of the dynamics. The main avalanche is associated with the disappearance of hidden order. Some experimental observations of figure-eight anomalies are discussed. It is argued they are a signal of a transient rearrangement of domain couplings, characteristic of amorphous and/or magnetically soft samples, and similar to evolution of kinetic glasses.

description: Agribusiness firms are often faced with the challenge of strategically managing employees to achieve a favorable position in the market (i.e. sustained competitive advantage). The resource based view (RBV) has been given considerable attention in the strategic management literature as a useful framework to analyze the significance of human resources in achieving sustained competitive advantage. However, there are few labor management studies in agribusiness that have used the RBV to provide evidence of a substantial relationship between any particular personnel management practice and competitive advantage. This paper provides an in-depth review of the RBV as a potential framework to analyze labor management practices in agribusiness. A case study is used to illustrate the application of this framework in the dairy industry and suggestions are made on how the framework can be extended and operationalized to guide future research and management practice in agribusiness
Compton scattering in the Klein-Nishina Regime Revisited
Creators: name: Kusunose, Masaaki
name: Takahara, Fumio
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In blazars such as 3C 279, GeV gamma-rays are thought to be produced by inverse Compton scattering of soft photons injected from external sources into the jet. Because of the large bulk Lorentz factor of the jet, the energy of soft photons is Doppler shifted in the comoving frame of the jet, and the scattering is likely to occur in the Klein-Nishina regime. Although the Klein-Nishina effects are well known, the properties of the electron and emission spectra have not been studied in detail in the environment of blazars. We solve the kinetic equation of electrons with the spatial escape term of the electrons to obtain the electron energy spectrum in the jet and calculated the observed emission spectrum. In calculations of the Compton losses in the Klein-Nishina regime, we use the discrete loss formalism to take into account the significant energy loss in a single scattering. Although the scattering cross section decreases because of the Klein-Nishina effects, ample gamma rays are emitted by inverse Compton scattering. When the injection spectrum of electrons obeys a power law, the electron spectrum does not follow a broken power law, as a result of the Klein-Nishina effects, and a large number of high-energy electrons remain in the emitting region.

description: We report a formula for the dry adiabatic lapse rate that depends on the compressibility factor and the adiabatic curves. Then, to take into account the non-ideal behavior of the gases, we consider molecules that can move, rotate, and vibrate and the information of molecular interactions through the virial coefficients. We deduce the compressibility factor in its virial expansion form and the adiabatic curves within the virial expansion up to any order. With this information and to illustrate the mentioned formula, we write the lapse rate for the ideal gas, and the virial expansion up to the second and third coefficient cases. To figure out the role of the virial coefficients and vibrations, under different atmospheric conditions, we calculate the lapse rate for Earth, Mars, Venus, Titan, and the exoplanet Gl 581d. Furthermore, for each one we consider three models in the virial expansion: van der Waals, square-well, and hard-sphere. Also, when possible, we compare our results to the experimental data. Finally, we remark that for Venus and Titan, which are under extreme conditions of pressure or temperature, our calculations are in good agreement with the observed values, in some instances.

description: Released in September 2009, Sustainable Food and Wine Value Chains is the final report of a 12 month residency in South Australia by Adelaide’s 14th Thinker in Residence, Professor Andrew Fearne. The paper overviews the residency journey and its outcomes, including a value chain research report, Vine to Dine; local food and wine enterprise/chain case studies, and the final report and its recommendations. Supply chains and value chains are differentiated as a basis for building value chain capacity; the attributes of some local case studies of businesses in the value chain paradigm are discussed and reference is made to the private and public benefits of value chain research. The case for state and national agri-food and wine industry development, strategic planning and policy to more fully embrace value chain principles is presented. Impediments to implementation of a national lamb industry chain project exemplify that change is needed, even for an investigation of the benefits of whole-of- chain focus on food by industry and government to occur. The gap between the Federal Minister for Agriculture’s views about food policy and the chain demarcation policies of farmer levy contributed research and development corporations suggests that these are issues which need to be addressed in the Minister’s initiation of a Productivity Commission inquiry into Rural Research and Development Corporations.

description: We consider a commonly studied supervised classification of a synthetic dataset whose labels are generated by feeding a one-layer neural network with random iid inputs. We study the generalization performances of standard classifiers in the high-dimensional regime where $α=n/d$ is kept finite in the limit of a high dimension $d$ and number of samples $n$. Our contribution is three-fold: First, we prove a formula for the generalization error achieved by $\ell_2$ regularized classifiers that minimize a convex loss. This formula was first obtained by the heuristic replica method of statistical physics. Secondly, focussing on commonly used loss functions and optimizing the $\ell_2$ regularization strength, we observe that while ridge regression performance is poor, logistic and hinge regression are surprisingly able to approach the Bayes-optimal generalization error extremely closely. As $α\to \infty$ they lead to Bayes-optimal rates, a fact that does not follow from predictions of margin-based generalization error bounds. Third, we design an optimal loss and regularizer that provably leads to Bayes-optimal generalization error.

description: This study describes the dynamics of COVID-19 deaths and infections via a Monte Carlo approach. The analyses include death's data from USA, Brazil, Mexico, UK, India and Russia, which comprise the four countries with the highest number of deaths/confirmed cases, as of Aug 07, 2020, according to the WHO. The Gompertz functions were fitted to the data of weekly averaged confirmed deaths per day by mapping the $χ^2$ values. The uncertainties, variances and covariances of the model parameters were calculated by propagation. The fitted functions for the average deaths per day for USA and India have an upward trend, with the former having a higher growth rate and quite huge uncertainties. For Mexico, UK and Russia, the fits are consistent with a slope down pattern. For Brazil we found a subtle trend down, but with significant uncertainties. The USA, UK and India data shown a first peak with a higher growth rate when compared to the second one, demonstrating the benefits of non-pharmaceutical interventions of sanitary measures and social distance flattening the curve. For USA, a third peak seems quite plausible, most likely related with the recent relaxation policies. Brazil's data are satisfactorily described by two highly overlapped Gompertz functions with similar growth rates, suggesting a two-steps process for the pandemic spreading. The 95% CI for the total number of deaths ($\times 10^3$) predicted by the model for Aug 31, 2020 are 160 to 220, 110 to 130, 59 to 62, 46.6 to 47.3, 54 to 63 and 16.0 to 16.7 for USA, Brazil, Mexico, UK, India and Russia, respectively. Our estimates for the prevalences of infections are in reasonable agreement with some preliminary reports from serological studies carried out in USA and Brazil. The method represents an effective framework to estimate the line-shape of the infection curves and the uncertainties of the relevant parameters based on the actual data.

description: We study the electronic structure of a strongly correlated d-wave superconducting state. Combining a renormalized mean field theory with direct calculation of matrix elements, we obtain explicit analytical results for the nodal Fermi velocity, v_F, the Fermi wave vector, k_F, and the momentum distribution, n_k, as a function of hole doping in a Gutzwiller projected d-wave superconductor. We calculate the energy dispersion, E_k, and spectral weight of the Gutzwiller-Bogoliubov quasiparticles, and find that the spectral weight associated with the quasiparticle excitation at the antinodal point shows a non monotonic behavior as a function of doping. Results are compared to angle resolved photoemission spectroscopy (ARPES) of the high temperature superconductors.

Knowledge Capabilities, Communication and Innovation in Beef Cattle Farm Enterprises

Subjects: Farm Management

description: A capabilities perspective of farm level innovation in the beef cattle industry is presented using information economics. The knowledge capabilities of non-corporate beef cattle enterprises have two interrelated components: the knowledge generated from the activities that takes place during production; and the information channels that producers possess to source external information. Although both are important for analysing innovation, the external information sources relating to producers’ knowledge are emphasised here. Emphasis on the path-dependent nature of knowledge focuses the discussion of innovation on the communication of information and how this affects the organisation of knowledge. The effects of differing knowledge capabilities are central to understanding the variation in innovative processes. Preliminary results from focus groups and in-depth interviews of both producers and their nominated information sources in the New England area of New South Wales in mid-2009 provide evidence for the efficacy of information channels. Case studies of innovations exemplify how differing attributes of innovations combine with network structures and institutional factors to influence the processes of communication between producers and their information sources. Communication of high quality information is shown to be more involved than simple exposure and must be considered from the point of view of the user, allowing it to be reconciled with existing knowledge of the producer. Of importance to producers is the source, delivery and history of the information and these are reflected in the approach taken in this research. The outcomes suggest that producers should be making decisions on the basis of their self organised knowledge capital rather than following innovations fashionable in the industry at large. The role of policy makers is to complement this by providing favourable conditions for knowledge capital formation where high quality information flows are likely outcomes. Policy makers could look at improving the ability of producers to integrate new technologies and practices into their production indirectly rather than looking to directly persuade them to adopt individual innovations.
A directional Gaussian smoothing optimization method for computational inverse design in nanophotonics

description: Local-gradient-based optimization approaches lack nonlocal exploration ability required for escaping from local minima in non-convex landscapes. A directional Gaussian smoothing (DGS) approach was recently proposed by the authors (Zhang et al., 2020) and used to define a truly nonlocal gradient, referred to as the DGS gradient, in order to enable nonlocal exploration in high-dimensional black-box optimization. Promising results show that replacing the traditional local gradient with the nonlocal DGS gradient can significantly improve the performance of gradient-based methods in optimizing highly multi-modal loss functions. However, the current DGS method is designed for unbounded and unconstrained optimization problems, making it inapplicable to real-world engineering design optimization problems where the tuning parameters are often bounded and the loss function is usually constrained by physical processes. In this work, we propose to extend the DGS approach to the constrained inverse design framework in order to find a better design. The proposed framework has its advantages in portability and flexibility to naturally incorporate the parameterization, physics simulation, and objective formulation together to build up an effective inverse design workflow. A series of adaptive strategies for smoothing radius and learning rate updating are developed to improve the computational efficiency and robustness. To enable a clear binarized design, a dynamic growth mechanism is imposed on the projection strength in parameterization. Our methodology is demonstrated by an example of designing a nanoscale wavelength demultiplexer and shows superior performance compared to the state-of-the-art approaches. By incorporating volume constraints, the optimized design achieves an equivalently high performance but significantly reduces the amount of material usage.

Tracing cultural un/belonging : the witch in Western feminist theory and literature
Creators: name: Szachowicz-Sempruch, Justyna
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this study is to examine selected narrative and theoretical feminist constructs of the 'witch' produced by women in the Western world over the last thirty years. The hypothesis is that the 'witch' figure is deployed to convey the diasporic or transgressive status of the/a 'woman' whose position is constructed as incompatible with the dominant phallogocentric discourse. The texts considered have been written in English, German, or Polish, since 1970. Bringing in a comparative dimension from the beginning, this dissertation demonstrates that despite differing political, cultural, and linguistic contexts, common 'threads' intertwine the destinies of the women conceptualized in these narratives as feminist (newly born, or re-discovered) witches, archaic mothers, and transgressive female boundary breakers. These reformulations of the 'witch' into a multiple site of strategic un/belonging, as proposed by the textual analyses in this study, converge with a number of theoretical concepts, such as Irigaray's proposal of a feminine "fluidity" that could shift the social order, Kristeva's "different legality" associated with a provisional, carnivalesque, but also strategically feminist project, as well as Butler's subversion of (Western) cultural foundations by undermining gender distinctions. While representing a range of theoretical standpoints, different languages, and different cultural backgrounds, all the texts discussed here contribute to the feminist deconstruction and redeployment of a phallogocentric archetype of the witch-woman. What this coming together implies in the end is that transnational exchanges of feminist theories and narratives produce 'boundary work' - works 'on the edge' that reveal the witch as a set of constructs that is both contested and difficult to displace in contemporary representations of 'woman'. This recognition offers a point of departure for a new political theorizing on 'woman' that rejects the Western epistemological dichotomies of subject/object, I/the other, or belonging and unbelonging as basic categories of identification.

description: The isometries of $AdS_5$ space and supersymmetric $AdS_5\otimes S_1$ space are nonlinearly realized on four dimensional Minkowski space. The resultant effective actions in terms of the Nambu-Goldstone modes are constructed. The dilatonic mode governing the motion of the Minkowski space probe brane into the covolume of supersymmetric $AdS_5$ space is found to be unstable and the bulk of the $AdS_5$ space is unable to sustain the brane. No such instablility appears in the non-supersymmetric case.

description: Fast radio bursts (FRBs) are a mysterious astrophysical phenomenon of bright pulses emitted at radio frequencies, and they are expected to be frequently detected in the future. The dispersion measures of FRBs are related to cosmological parameters, thus FRBs have the potential to be developed into a new cosmological probe if their data can be largely accumulated in the future. In this work, we study the capability of future FRB data to improve cosmological parameter estimation in two dynamical dark energy models. We find that the simulated FRB data can break the parameter degeneracies inherent in the current cosmic microwave background (CMB) data. Therefore, the combination of the CMB and FRB data can significantly improve the constraints on the Hubble constant and dark energy parameters, compared to those using CMB or FRB alone. If 10,000 FRB events with known redshifts are detected in the future, they would perform better than the baryon acoustic oscillation (BAO) data in breaking the parameter degeneracies inherent in the CMB data. We also find that the combination of FRB and gravitational-wave (GW) standard siren data provides an independent low-redshift probe to verify the results from the CMB and BAO data. For the data combination of CMB, GW, and FRB, it is found that the main contribution to the constraints comes from the CMB and GW data, but the inclusion of the FRB data still can evidently improve the constraint on the baryon density.
