The Effect of a Binary Source Companion on the Astrometric Microlensing Behavior
Creators: name: Han, Cheongho
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: If gravitational microlensing occurs in a binary-source system, both source components are magnified, and the resulting light curve deviates from the standard one of a single source event. However, in most cases only one source component is highly magnified and the other component (the companion) can be treated as a simple blending source: blending approximation. In this paper, we show that, unlike the light curves, the astrometric curves, representing the trajectories of the source image centroid, of an important fraction of binary-source events will not be sufficiently well modeled by the blending effect alone. This is because the centroid shift induced by the source companion endures to considerable distances from the lens. Therefore, in determining the lens parameters from astrometric curves to be measured by future high-precision astrometric instruments, it will be important to take the full effect of the source companion into consideration.

description: We study the spectral and temporal properties of three Type I X-ray bursts observed from Cyg X-2 with the Rossi X-ray Timing Explorer. Despite the short time durations (~ 5 sec) these bursts show radial expansion of order of several neutron star (NS) radii. We apply the analytical models of spectral formation during the expansion and contraction stages to derive physical conditions for the matter in the burning zone close to the surface of the NS as well as the NS mass-radius relation. Our results, combined with statistical errors, show that the central object is a compact star with mass ~1.4 solar masses and radius ~9 km. Our results favor the softer equation of state for neutron star matter.

title: Multifunctional Composite Frameworks for Advanced Lithium-Sulfur Batteries
Creators: name: Hencz, Luke
Publisher: name: Griffith University
Year: 2021
Subjects: subject: lithium-sulfur batteries
subject: polysulfide shuttle
subject: multifunctional composite frameworks

description: Rechargeable batteries have recently solidified their role in society’s transition toward a cleaner energy future through the emergence of electric vehicles and grid-scale energy storage. The deployment of electrochemical energy storage near electricity generators and at home has increased the reliability of renewable energy, thus easing renewable energy’s emergence into power grids worldwide. Similarly, electric vehicles have continued to increase their implementation into global transportation networks, which reduces the reliance on fossil fuelbased vehicles and helps mitigate CO2 emissions. At present, lithium-ion batteries (LIBs) dominate the portable electronics market due to their superior energy density. However, as lithium-ion batteries are late in their development cycle, the limitations of the technology are becoming apparent, and researchers have turned to new battery chemistries to enhance the energy density, reduce the cost, and mitigate the environmental impacts of current-generation batteries. Lithium-sulfur batteries (Li−S) are an excellent example of next-generation batteries, and can deliver higher energy densities, reduce costs, and minimise environmental impacts over current-generation LIBs. However, Li−S batteries have technical limitations associated with their chemistry. The most troublesome limitation of the Li−S cell is the dubbed the polysulfide shuttle and refers to the dissolution and migration of soluble discharge intermediates which results in rapid capacity fading. Other limitations revolve around the limited conductivity of sulfur cathodes, volume expansion of electroactive materials, and poor performance at high current densities. Researchers have focused on various cell components to address the limitations, with substantial research on the cathode, anode, and electrolyte. This thesis employs strategies targeted at the composite sulfur cathode in lithium-sulfur cells.

description: We present the BeppoSAX observations of 3C 279 performed in 1997 January 13-23 simultaneously with gamma-ray pointings with EGRET on board CGRO and optical observations at the Torino Observatory (1997 January 11-18). ISO data close to this epoch are also available. We compare the derived Spectral Energy Distribution with those obtained at all other epochs with adequate multiwavelength coverage. Simple spectral models fitted to the multiepoch SEDs suggest that changes in intensity can be ascribed mainly to the variation of the bulk Lorentz factor of the plasma in the jet.

description: We investigate the fundamental plane (FP) evolution of early-type galaxies in the IllustrisTNG-100 simulation (TNG100) from redshift $z=0$ to $z=2$. We find that a tight plane relation already exists as early as $z=2$. Its scatter stays as low as $\sim 0.08$ dex across this redshift range. Both slope parameters $b$ and $c$ (where $R \propto σ^b I^c$ with $R$, $σ$, and $I$ being the typical size, velocity dispersion, and surface brightness) of the plane evolve mildly since $z=2$, roughly consistent with observations. The FP residual $\rm Res$ ($\equiv\,a\,+\,b\log σ\,+\,c\log I\,-\,\log R$, where $a$ is the zero point of the FP) is found to strongly correlate with stellar age, indicating that stellar age can be used as a crucial fourth parameter of the FP. However, we find that $4c+b+2=δ$, where $δ\sim 0.8$ for FPs in TNG, rather than zero as is typically inferred from observations. This implies that a tight power-law relation between the dynamical mass-to-light ratio $M_{\rm dyn}/L$ and the dynamical mass $M_{\rm dyn}$ (where $M_{\rm dyn}\equiv 5σ^2R/G$, with $G$ being the gravitational constant) is not present in the TNG100 simulation. Recovering such a relation requires proper mixing between dark matter and baryons, as well as star formation occurring with correct efficiencies at the right mass scales. This represents a powerful constraint on the numerical models, which has to be satisfied in future hydrodynamical simulations.

description: This exegesis contextualises my feature-length film The Sultan and the Kings, a studio-based project produced for the Doctorate of Visual Arts. As a Kurdish émigré and filmmaker who left Iran in 1997, lived in Turkey for a couple of years, then emigrated to Australia in 2000, I studied film and also continued the filmmaking practice that I had begun in Iran in 1988. The exegesis examines the shortage of literature about Kurdish films, the misrepresentation of Kurdish filmmaking, the emergence of Kurdish cinema and the obstacles faced by it, as well as the emergence of Kurdish cinematic styles. By considering how my film relates to Kurdish cinema overall, what is referred to as the “cinema under oppression” and the “cinema of diaspora”, this exegesis examines the development of a form of storytelling that I term digital docu-fiction, which blends elements of documentary, fiction and digital film manipulation. Through this form of practice, Kurdish filmmakers aim to take control of the whole process of filmmaking, from production to exhibition. The exegesis discusses this form of storytelling with reference to the development of my own practice and aesthetic, using my short film A Woman with a Digital Camera as an example of digital docu-fiction.

description: The ability to transfer knowledge to novel environments and tasks is a sensible desiderata for general learning agents. Despite the apparent promises, transfer in RL is still an open and little exploited research area. In this paper, we take a brand-new perspective about transfer: we suggest that the ability to assign credit unveils structural invariants in the tasks that can be transferred to make RL more sample-efficient. Our main contribution is SECRET, a novel approach to transfer learning for RL that uses a backward-view credit assignment mechanism based on a self-attentive architecture. Two aspects are key to its generality: it learns to assign credit as a separate offline supervised process and exclusively modifies the reward function. Consequently, it can be supplemented by transfer methods that do not modify the reward function and it can be plugged on top of any RL algorithm.

title: Therapeutic Effects of Selective Androgen Receptor Modulation in the Treatment of Cardiac, Metabolic and Bone Pathologies Associated with Androgen Decline and Obesity
Creators: name: Donner, Daniel Giordano
Publisher: name: Griffith University
Year: 2015
Subjects: subject: Metabolic syndrome (MetS)
subject: Testosterone deficiency (TD)
subject: Cardiovascular disease
subject: Osteoporotic bone fragility

description: In males, the widespread prevalence of both obesity-related metabolic syndrome (MetS) and testosterone deficiency (TD) is further exacerbating the socio-economic and health burdens already elicited by the rapidly ageing global population. The strong reciprocal relationship between the MetS and TD in males often results in their shared pathologies presenting together in the clinical setting. Clinical and epidemiological studies have provided convincing evidence that the MetS and TD are highly comorbid [1, 2] and share mutual abnormalities, including visceral obesity, dyslipidaemia and insulin resistance. One or more of these changes associated with the MetS and TD contribute to life-threatening conditions such as cardiovascular disease and increased osteoporotic bone fragility, particularly in the ageing male. Due to limitations of traditional androgen replacement therapy with testosterone (TEST), which is readily converted to active metabolites by enzymes, the therapeutic potential of trenbolone (TREN), a selective androgen receptor modulator (SARM), remains an attractive alternative to TEST. However, TREN’s efficacy has not been investigated in appropriate models representative of obese and TEST-deficient males, especially within the context of cardiometabolic disease and obesity-related osteoporosis/bone strength.

description: This study investigated the environmental drivers of flowering in a common seagrass species (Zostera muelleri) across Australasia. It involved field surveys conducted in seagrass meadows on Australia’s East coast, mesocosm, and climate-controlled experiments, as well as large-scale modeling of seagrass flowering along the latitudinal gradient in Australasia. The results support finding optimal flower collection times for seed-based restoration, predicting climate-induced changes in flowering times, and guiding the design of seagrass seed nurseries.

description: We demonstrate that there is a clear statistical correlation between the (X,Y,Z,V_r) phase-space distribution of the outer halo Galactic globular clusters (having 10 kpc <= R_GC <= 40 kpc) and the orbital path of the Sagittarius dwarf spheroidal galaxy (Sgr dSph), as derived by Ibata & Lewis. At least 4 of the sample of 35 globular clusters in this distance range were formerly members of the Sgr galaxy (at the 95 % confidence level), and are now distributed along the Sgr Stream, a giant tidal structure that surrounds the Milky Way. This is the first instance that a statistically significant structure associated with the Sgr dSph has been detected in the globular cluster population of the Galactic halo. Together with the four well-known globular clusters that are located near the center of this tidally-disrupting dwarf galaxy, these clusters constitute ~ 20 % of the population of outer halo (R_GC >= 10 kpc) clusters. The Sgr dSph was therefore not only an important contributor to the halo field star population, but it also had a significant role in the building-up of the globular cluster system of the Milky Way.

Institutional challenges to developing a Nigerian climate policy

Subjects: subject: 300 Sozialwissenschaften::320 Politikwissenschaft

description: This paper discusses the structural basis and practice of creating a climate policy framework in Nigeria. The roles of existing and planned institutions and legal frameworks are discussed, as well as how they foster or hinder the design of policies and implementation of climate responses at the domestic and international levels. Data has been collected between autumn 2009 and spring 2010. The paper combines literature review with empirical data from interviews of various actors in the Nigerian climate policy process. Various actors including the federal and state governments, civil society and private sector interest groups as well as the Nigerian oil sector are working conjointly on the elaboration of political frameworks and on the realisation of a multitude of individual projects focused on climate change. The paper examines the role of the institutional framework compassing this multitude of stakeholders for the creation of a sustainable climate policy in Nigeria, thereby discussing and referring to literature on institutional governance in the environment sector and institutional change for sustainability. Currently, there is a lack of cohesion between political initiatives and institutions, and a weak implementation of environmental laws and directives. Although becoming a topic of increasing political interest, a policy framework on climate change is still nonexistent for Nigeria – caused not least by diverging lines of interest between participating institutions. The paper shows that once awareness about climate change has been created, there is a danger of the proliferation of institutions and actors addressing the various dimensions of climate change. This proliferation highlights the lack of coordination between various government entities and their struggle to gain/retain influence over the national climate policy, thereby slowing down the design and implementation of responses to mitigate and adapt to climate change. Suggestions are made on how the barriers to climate policy development and implementation in Nigeria can be overcome.

description: We present a simple and computationally efficient coarse-grained and solvent- free model for simulating lipid bilayer membranes. In order to be used in concert with particle-based reaction-diffusion simulations, the model is purely based on interacting and reacting particles, each representing a coarse patch of a lipid monolayer. Particle interactions include nearest-neighbor bond-stretching and angle-bending and are parameterized so as to reproduce the local membrane mechanics given by the Helfrich energy density over a range of relevant curvatures. In-plane fluidity is implemented with Monte Carlo bond- flipping moves. The physical accuracy of the model is verified by five tests: (i) Power spectrum analysis of equilibrium thermal undulations is used to verify that the particle-based representation correctly captures the dynamics predicted by the continuum model of fluid membranes. (ii) It is verified that the input bending stiffness, against which the potential parameters are optimized, is accurately recovered. (iii) Isothermal area compressibility modulus of the membrane is calculated and is shown to be tunable to reproduce available values for different lipid bilayers, independent of the bending rigidity. (iv) Simulation of two-dimensional shear flow under a gravity force is employed to measure the effective in-plane viscosity of the membrane model and show the possibility of modeling membranes with specified viscosities. (v) Interaction of the bilayer membrane with a spherical nanoparticle is modeled as a test case for large membrane deformations and budding involved in cellular processes such as endocytosis. The results are shown to coincide well with the predicted behavior of continuum models, and the membrane model successfully mimics the expected budding behavior. We expect our model to be of high practical usability for ultra coarse-grained molecular dynamics or particle-based reaction-diffusion simulations of biological systems.

description: We present results on over 100 high-redshift quasars found in the Sloan Digital Sky Survey (SDSS), using automated selection algorithms applied to SDSS imaging data and with spectroscopic confirmation obtained during routine spectroscopic operations of the Sloan 2.5-m telescope. The SDSS spectra cover the wavelength range 3900--9200 Angstroms at a spectral resolution of 1800, and have been obtained for 116 quasars with redshifts greater than 3.94; 92 of these objects were previously uncataloged, significantly increasing the current tally of published z>4 quasars. The paper also reports observations of five additional new z>4.6 quasars; all were found from the SDSS imaging survey and spectroscopically confirmed with data from the Apache Point Observatory's 3.5-m telescope. The i' magnitudes of the quasars range from 18.03 to 20.56. Of the 97 new objects in this paper, 13 are Broad Absorption Line quasars. Five quasars, including one object at a redshift of 5.11, have 20 cm peak flux densities greater than 1 mJy. Two of the quasars, both at z=4.5, have very weak emission lines; one of these objects is a radio source. Nineteen of the newly-discovered objects have redshifts above 4.6, and the maximum redshift is z=5.41; among objects reported to date, the latter is the third highest redshift AGN, and penultimate in redshift among luminous quasars.

description: In this Letter we report the first calculation of all ${\cal O}(α_s)$ medium-induced branching processes to any order in opacity. Our splitting functions results are presented as iterative solutions to matrix equations with initial conditions set by the leading order branchings in the vacuum. The flavor and quark mass dependence of the in-medium $q \rightarrow qg$, $g\rightarrow gg$, $q \rightarrow g q$, $g \rightarrow q\bar{q}$ processes is fully captured by the light-front wavefunction formalism and the color representation of the parent and daughter partons. We include the explicit solutions to second order in opacity as supplementary material and present numerical results in a realistic strongly-interacting medium produced in high center-of-mass energy heavy ion collisions at the Large Hadron Collider. Our numerical simulations show that the second order in opacity corrections can change the energy dependence of the in-medium shower intensity. We further find corrections to the longitudinal and angular distributions of the in-medium splitting kernels that may have important implications for jet substructure phenomenology.

description: We compute hadronic transitions between heavy quarkonium states with two, or one, pion/eta particles in the final state. We use the multipole expansion but not the twist expansion. The latter cannot be justified for the energy release of hadronic transitions between heavy quarkonium states with different principal quantum numbers. Instead, we use a counting based on the dimension of the interpolating field of the hybrid. This alternative counting allows us to still use chiral low-energy theorems to compute the pion production by local gluonic operators. We explore the phenomenological impact of this counting. Remarkably enough, for the two-pion transitions, we obtain the same predictions for the normalized differential decay rate as those obtained assuming the twist expansion. We implement this computational scheme using the hadronic representation of the effective theory potential NRQCD. We assume that the inverse Bohr radius of the heavy quarkonium is much larger than $Λ_{\rm QCD}$ but do not impose any constraint on the relative size of $Λ_{\rm QCD}$ and the typical kinetic energy of the bound state.

description: We perform evolutionary calculations for a binary system with initial parameters: $M_{sg,i}$= 1$M\odot$ and $M_{ns,i}$= 1.4 $M\odot$ and $P_{orb,i}(RLOF)$= 1.27 d to produce observed binary parameters for the PSR J1740--5340. Our calculations support model proposed by D'Amico et al. (2001) in which this binary may be progenitor of a millisecond pulsar + helium white dwarf system. We propose observational test to verify this hypothesis. If the optical companion lack of carbon lines in its spectrum shows but the oxygen and nitrogen lines are present then our model correctly describes the evolutionary stage of PSR J1740--5340.

Measurement of $W^\pm$ boson production in Pb+Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV with the ATLAS detector

description: A measurement of $W^\pm$ boson production in lead-lead collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV is reported using data recorded by the ATLAS experiment at the LHC in 2015, corresponding to a total integrated luminosity of $0.49\;\mathrm{nb^{-1}}$. The $W^\pm$ bosons are reconstructed in the electron or muon leptonic decay channels. Production yields of leptonically decaying $W^\pm$ bosons, normalised by the total number of minimum-bias events and the nuclear thickness function, are measured within a fiducial region defined by the detector acceptance and the main kinematic requirements. These normalised yields are measured separately for $W^+$ and $W^-$ bosons, and are presented as a function of the absolute value of pseudorapidity of the charged lepton and of the collision centrality. The lepton charge asymmetry is also measured as a function of the absolute value of lepton pseudorapidity. In addition, nuclear modification factors are calculated using the $W^\pm$ boson production cross-sections measured in $pp$ collisions. The results are compared with predictions based on next-to-leading-order calculations with CT14 parton distribution functions as well as with predictions obtained with the EPPS16 and nCTEQ15 nuclear parton distribution functions. No dependence of normalised production yields on centrality and a good agreement with predictions are observed for mid-central and central collisions. For peripheral collisions, the data agree with predictions within 1.7 (0.9) standard deviations for $W^-$ ($W^+$) bosons.

Kinetic Sunyaev-Zel'dovich effect from halo rotation
Creators: name: Cooray, Asantha
name: Chen, Xuelei
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss the kinetic Sunyaev-Zel'dovich (SZ) contribution to cosmic microwave background (CMB) temperature fluctuations due to coherent rotational velocity component of electrons within halos. This effect produces a distinct dipole-like temperature distribution across the the cluster, and provides a promising way to measure the angular momentum distribution of gas inside clusters. Information obtained from such a measurement may provide new insights to the origin and evolution of angular momentum in hierarchical structure formation theory. For typical, well relaxed, clusters of mass a few times 10$^{14}$ M$_{\sun}$, the peak fluctuation is of the order a few $μ$K, depending on the rotational velocity and the inclination angle of the rotational axis. For clusters which had underwent a recent merger, the contribution to temperature fluctuations could be even larger. This dipole signature is similar to the one produced by lensed CMB towards galaxy clusters, though the lensing contribution spans a larger angular extent than the one due to rotational scattering as the former depends on the gradient of the cluster potential. Since the lensing contribution towards clusters are aligned with the large scale CMB gradient, when higher resolution observations towards clusters are combined with a wide field CMB map, these two effects can be separated. An additional, but less important, source of confusion is the dipolar pattern produced by the moving-lens effect involving, again, the gradient of the cluster potential and the transverse velocity. The angular power spectrum of temperature anisotropies produced by the halo rotation is expected to be smaller than those due to the thermal SZ and peculiar velocity kinetic SZ effects.

description: The evolution of two slow--rolling scalar fields with potentials of the form $V=V_0 ϕ^{-α}\exp(-βϕ^m)$ is studied. Considering different values of the parameters $α$, $β$ and $m$, we derive several new inflationary solutions in which one fields just evolves in the background and is not important for the inflationary dynamics. In addition, we find new solutions where both fields are dynamically important during inflation. Moreover, we discuss the evolution of perturbations in both scalar fields and the spacetime metric, concentrating on the production of entropy perturbations. We find that for a large region in parameter space and initial conditions tensor modes are negligible and that adiabatic and isocurvature perturbations are essentially uncorrelated.

ROSAT X-ray observations of the dwarf galaxy Holmberg II

description: We present a study of the irregular dwarf galaxy Holmberg II based on ROSAT PSPC observations (total exposure time: 22 ksec). Holmberg II is a nearby (3.2 Mpc), well-studied dwarf irregular galaxy. It is famous for its interstellar medium which is dominated by expanding structures such as HI holes and shells. We search for X-ray emission from point sources as well as for diffuse emission, down to the detection limit of the ROSAT data. Using X-ray hardness ratio diagrams we differentiate between thermal plasma and power-law X-ray spectra which helps to determine the nature of the individual sources. Correlating the X-ray data with complementary observations ranging from the far-ultraviolet to the radio regime we increase the probability of correctly identifying sources belonging to Holmberg II. We did not detect soft X-ray emission originating from hot gas within supergiant HI shells above our luminosity sensitivity limit of (L_limit(0.1 - 2.1 keV) ~ 10^{37}erg/s). This finding can probably be attributed to blow-out in the case of the largest holes and insufficient sensitivity (due to strong photoelectric absorption) in case of the smaller HI holes. However we find faint X-ray sources well beyond the stellar body but within the HI distribution of Holmberg II, which suggests the presence of X-ray binaries. This indicates that star formation has taken place across the entire gaseous disk of Holmberg II in the past, some of which may have created the structures seen in the ISM at large galactocentric radii.

description: The real-time flux dynamics of up to three superconducting quantum interference devices (SQUIDs) are studied by numerically solving the time-dependent Schrödinger equation. The numerical results are used to scrutinize the mapping of the flux degrees of freedom onto two-level systems (the qubits) as well as the performance of the intermediate SQUID as a tunable coupling element. It is shown that the qubit representation yields a good description of the flux dynamics during quantum annealing and the presence of the tunable coupling element does not have negative effects on the overall performance. Additionally, data obtained from a simulation of the dynamics of two-level systems during quantum annealing are compared to experimental data produced by the D-Wave 2000Q quantum annealer. The effects of finite temperature are incorporated in the simulation by coupling the qubit system to a bath of two-level systems. It is shown that an environment modeled as non-interacting two-level systems coupled to the qubits can produce data which matches the experimental data much better than the simulation data of the qubits without coupling to an environment and better than data obtained from a simulation of an environment modeled as interacting two-level systems coupling to the qubits.
