description: The correlation observed between monochromatic X-ray and UV luminosities in radiatively-efficient active galactic nuclei (AGN) lacks a clear theoretical explanation despite being used for many applications. Such a correlation, with its small intrinsic scatter and its slope that is smaller than unity in log space, represents the compelling evidence that a mechanism regulating the energetic interaction between the accretion disk and the X-ray corona must be in place. This ensures that going from fainter to brighter sources the coronal emission increases less than the disk emission. We discuss here a self-consistently coupled disk-corona model that can identify this regulating mechanism in terms of modified viscosity prescriptions in the accretion disk. The model predicts a lower fraction of accretion power dissipated in the corona for higher accretion states. We then present a quantitative observational test of the model using a reference sample of broad-line AGN and modeling the disk-corona emission for each source in the $L_X-L_{UV}$ plane. We used the slope, normalization, and scatter of the observed relation to constrain the parameters of the theoretical model. For non-spinning black holes and static coronae, we find that the accretion prescriptions that match the observed slope of the $L_X-L_{UV}$ relation produce X-rays that are too weak with respect to the normalization of the observed relation. Instead, considering moderately-outflowing Comptonizing coronae and/or a more realistic high-spinning black hole population significantly relax the tension between the strength of the observed and modeled X-ray emission, while also predicting very low intrinsic scatter in the $L_X-L_{UV}$ relation. In particular, this latter scenario traces a known selection effect of flux-limited samples that preferentially select high-spinning, hence brighter, sources.

(synonyms and major subsequent citations).
DIAGNOSIS (adapted and modified from Bernardi, 1973): Head broad, hemispherical; proboscis small, barely visible past oral margin; basal flagellomere drop shaped, with three slender, apical flagellar articles forming stylus, apical article longest and fine; venation with few or generally no apical radial and medial cells; cell cup absent; hypandrium (male) highly reduced or lost; female cerci long, tapered, apically pointed.
 TYPE SPECIES: Hirmoneura obscura (Wiedemann), Recent.
 COMMENTS: Hirmoneura are one of the three largest genera in the Nemestrinidae after Trichophthalma Westwood and Nemestrinus Latreille. It contains approximately 50 described living species distributed nearly equally between Old and New worlds (Bernardi, 1973). The venation of this genus and the two largest ones (above) are very similar and generalized, with the least amount of vein coalescence among nemestrinid genera; these genera also share similarities in antennal structure and a distinctive modification of the ocelli, where the anterior ocellus is separated considerably anterior to the posterior ones and on a separate mound. These three genera are probably closely related, though phylogenetic work is needed to test this. Interestingly, in the one Burmese amber specimen in which the dorsum of the head is visible, the ocelli are unmodified, no doubt plesiomorphically. The female cerci of Hirmoneura caudoprima, however, are extended into a long, tapered, pointed oviscapt, like many of the modern species of the genus. All three of the Burmese amber species also lack the dense, long pilosity of modern species. Monophyly of modern Hirmoneura is supported by a hypandrium in the male that is small or usually lost, unknown for the fossil taxa. There are three species of Hirmoneura based on compression fossils from the Early Cretaceous of Spain and Siberia (Mostovski and Delclòs, 2000); these have a closed cell cup. The genus is also recorded from the Cenozoic (Wedmann, 2007). Otherwise, the venation of Cretaceous Hirmoneura is remarkably similar to modern species, but this may just be a plesiomorphic resemblance, as the ocelli of the amber Hirmoneura suggests these three species to be stem groups. The recent venation terminology is used here rather than that in Bernardi’s (1973) work, with differences as follows: R 3+4 (vs. R 4 in Bernardi), M 3 +CuA 1 (vs. M 3 +M 4), CuA 2 (vs. Cu 1).

 Material examined. Cape Ferguson, Turtle Bay, intertidal in C. prolifera, 12 July 1999, one X. Cairns Marina, fouling panels with bryozoans and hydroids, 2 m, November 1999, 16 W, 21 X, nine juveniles; February 2001, 30 X, 29 W 17 with eggs, three juveniles (coll. O. Floerl).
 Description. Trunk 1.04 mm long and 0.4 mm wide, segmented, smooth, crurigers separated by their diameter. Ocular tubercle broad, of conical shape, taller than abdomen, with yellowish pigmented eyes; proboscis short, slightly tapering distally, crown of short setae around oral surface. Ovigers seven-segmented, distal segments with recurved spinules. Femur and second tibia subequal, caeca visible through cuticle distributed in pockets along the legs, first coxa with a distal pointed tubercle, three pointed spines distally in the female femur, one dorsal spine on first tibia and short setae on second tibia. Propodus with strong heel, three spines and six sole spines, main claw half the length of the propodus and auxiliaries threequarters the length of the main claw.
 Distribution. Endeis flaccida has not been recorded from Australia before; however, there are unreported records of sea spiders collected in Queensland and New South Wales identified as E. flaccida (sic. E. flaecida) deposited at the AM. This is a widely distributed species known from the Indo-west Pacific region, the coasts of South Florida and both sides of the Isthmus of Panama.
 Remarks. The species is recognizable by the combination of visible conglomerate guts especially in the tibiae and femora and the absence of prominences or long spines. Depth and habitat is similar to where the species has been found before. It seems to be seasonally abundant, most of the males being ovigerous between November and March at this specific site, where it has been found amongst hydroids on fouling panels.

description: A generalized M1 sum rule for orbital magnetic dipole strength from excited symmetric states to mixed-symmetry states is considered within the proton-neutron interacting boson model of even-even nuclei. Analytic expressions for the dominant terms in the B(M1) transition rates from the first and second $2^+$ states are derived in the U(5) and SO(6) dynamic symmetry limits of the model, and the applicability of a sum rule approach is examined at and in-between these limits. Lastly, the sum rule is applied to the new data on mixed-symmetry states of 94Mo and a quadrupole d-boson ratio $nd(0^+_1)/nd(2^+_2) \approx 0.6$ is obtained in a largely parameter-independent way

description: We present near-infrared spectroscopy of the sporadically active asteroid (6478) Gault collected on the 3 m NASA/Infrared Telescope Facility observatory in late 2019 March/early April. Long-exposure imaging with the 0.5 m NEEMO T05 telescope and previously published data simultaneously monitored the asteroid activity, providing context for our measurements. We confirm Gault is a silicate-rich (Q- or S-type) object likely linked to the (25) Phocaea collisional family. The asteroid exhibits substantial spectral variability over the 0.75-2.45 $μ$m wavelength range, from unusual blue (s'=-13.5+/-1.1% $μ$m-1 to typical red (s'=+9.1+/-1.2% $μ$m-1) spectral slope, that does not seem to correlate with activity. Spectral comparisons with samples of ordinary chondrite meteorites suggest that the blue color relates to the partial loss of the asteroid dust regolith, exposing a fresh, dust-free material at its surface. The existence of asteroids rotating close to rotational break-up limit and having similar spectral properties as Gault further supports this interpretation. Future spectroscopic observations of Gault, when the tails dissipate, will help further testing of our proposed hypothesis.

description: We present new high-resolution HI observations of the disk of the collisional infrared luminous (L$_{\rm IR}=2.2\times10^{11}$ L$_{\sun}$) galaxy NGC 1144, which reveal an apparent large-scale azimuthal and kinematic segregation of neutral hydrogen relative to the molecular gas distribution. Even among violently collisional galaxies, the CO/HI asymmetry in NGC 1144 is unusual, both in the inner regions, and in the outer disk. We suggest that we are observing Arp 118 at a special moment, shortly after a high-speed collision between NGC 1144 and its elliptical companion NGC 1143. HI emission with an average molecular fraction f$_{mol}$ $$ 400 km s$^{-1}$) rotational velocities can explain: 1) the CO/HI asymmetries, 2) a large velocity jump (185 km s$^{-1}$) across the arm as measured by HI absorption against a radio bright continuum source which straddles the arm, and 3) the asymmetric distribution of star formation and off-nuclear molecular gas resulting from likely streaming motions associated with the strong-shock. The new results provide for the first time a coherent picture of Arp 118's many peculiarities, and underlines the potentially complex changes in the gas-phase that can accompany large gravitational perturbations of gas-rich galaxies.

description: In this study, we examined the temporal variation in calling activity of a field cricket, Acanthogryllus asiaticus on a diel and seasonal scale. We also examined the acoustic structure of calls produced in the context of mating, namely, long distance mating call (LDMC), courtship call and post copulatory call. Finally, we examined the allometric relationship between sound-producing structures and body morphometry and tested whether peak frequency of LDMC was indicative of male body size. Our findings suggest that calling activity of A. asiaticus peaked between 2100 and 2400 h on a diel scale and between March and May (summer) on a seasonal scale. The three calls were acoustically distinct and stereotypic with the courtship and post copulatory calls being composed of two chirp-types each. This study presents the first description of post copulatory calls of a field cricket. Morphometric analyses revealed that both inter-tooth distance and teeth width varied along the file length, however, number of teeth and file length were not correlated. Harp area was correlated with body size and peak frequency was significantly negatively correlated with harp area. This implies that the peak frequency can potentially be an indicator of body size in this species.

description: With 40 ks of Chandra ACIS-S3 exposure, new information on both the starburst and QSO components of the X-ray emission of Markarian 231, an ultraluminous infrared galaxy and Broad Absorption Line QSO, has been obtained. The bulk of the X-ray luminosity is emitted from an unresolved nuclear point source, and the spectrum is remarkably hard with the majority of the flux emitted above 2 keV. Most notably, significant nuclear variability (a decrease of ~45% in approximately 6 hours) at energies above 2 keV indicates that Chandra has probed within light hours of the central black hole. Though we concur with Maloney & Reynolds that the direct continuum is not observed, this variability coupled with the 188 eV upper limit on the equivalent width of the FeKalpha emission line argues against the reflection-dominated model put forth by these authors based on their ASCA data. Instead, we favor a model in which a small, Compton-thick absorber blocks the direct X-rays, and only indirect, scattered X-rays from multiple lines of sight can reach the observer. Extended soft, thermal emission encompasses the optical extent of the galaxy and exhibits resolved structure. An off-nuclear X-ray source with a 0.35-8.0 keV luminosity of L_X=7x10^{39} erg s^{-1}, consistent with the ultraluminous X-ray sources in other nearby starbursts, is detected. We also present an unpublished FOS spectrum from the HST archive showing the broad C IV absorption.

A Quest for justice : the millenary aspirations of a contemporary Javanese Wali
Creators: name: Suwandi, Raharjo
Publisher: name: The Australian National University
Year: 1985

description: THERE EXIST, without doubt, two ways in which a comparatively large and complex society like that of the Javanese can be investigated; firstly, through a thorough study at a general level and, secondly, through exhaustive study at the local level. The revival in the study of Javanese society after the war, particularly the one initiated by the Mojokuto project, has produced several general studies on Java such as those by Geertz, Dewey, Jay. For the last two decades, however, there has existed a trend with strong emphasis on local studies as a way of understanding the complexity of Javanese social development. This is particularly observable from some fine local studies by social historians such as Onghokham, Elson, Fernando, but also by other social scientists, such as Penny Singarimbun.

description: The $ω$-meson photoproduction, $γ+p\to p+ω$, is studied in the framework of a model, containing $π$-meson exchange in t-channel and nucleon-exchange in s- and u-channels. Considering both $ωNN$-coupling constants in the region of time-like meson four momenta as the free parameters, we find different sets of solutions for these constants from the existing data on the t-dependence of the differential cross sections, $dσ(γ+p\to p+ω)/dt$, in the near threshold region $E_γ\leq 2$ GeV. These sets of $ωNN$-coupling constants, corresponding to destructive and constructive $π\bigotimes N$-interference contributions to $dσ/dt$ can be well distinguished by measurements of beam asymmetry, induced by linear photon polarization.

description: The various ionization mechanisms at play in active galactic nuclei (AGN) and quasars have been well studied, but relatively little has been done to separately investigate the contributions of these ionization mechanisms within the host galaxy and outflowing components. Using Gemini integral field spectroscopy (IFS) data, we study the ionization properties of these two components in four nearby ($z \lesssim$ 0.2) radio-quiet Type 1 quasars. Emission line ratios and widths are employed to identify the dominant ionization mechanisms for the host and outflow components in each object. We find that photoionization by the AGN often dominates the ionization of both gaseous components in these systems. In three cases, the outflowing gas is more highly ionized than the gas in the host, indicating that it is more strongly exposed to the ionizing radiation field of the AGN. In two objects, a positive correlation between the line widths and line ratios in the outflowing gas component indicates that shocks with velocities of order 100 $-$ 500 km s$^{-1}$ may also be contributing to the ionization and heating of the outflowing gas component. The line ratios in the outflowing gas of one of these two objects also suggest a significant contribution from photoionization by hot, young stars in the portion of the outflow that is closest to star-forming regions in the host galaxy component. The data thus favor photoionization by hot stars in the host galaxy rather than stars formed in the outflow itself.

description: We address the fundamental question of how to optimally probe a scene with electromagnetic (EM) radiation to yield a maximum amount of information relevant to a particular task. Machine learning (ML) techniques have emerged as powerful tools to extract task-relevant information from a wide variety of EM measurements, ranging from optics to the microwave domain. However, given the ability to actively illuminate a particular scene with a programmable EM wavefront, it is often not clear what wavefronts optimally encode information for the task at hand (e.g., object detection, classification). Here, we show that by integrating a physical model of scene illumination and detection into a ML pipeline, we can jointly learn optimal sampling and measurement processing strategies for a given task. We consider in simulation the example of classifying objects using microwave radiation produced by dynamic metasurfaces. By integrating an analytical forward model describing the metamaterial elements as coupled dipoles into the ML pipeline, we jointly train analog model weights with digital neural network weights. The learned non-intuitive illumination settings yield a higher classification accuracy using fewer measurements. On the practical level, these results are highly relevant to emerging context-aware systems such as autonomous vehicles, touchless human-interactive devices or within smart health care, where strict time constraints place severe limits on measurement strategies. On the conceptual level, our work serves as a bridge between wavefront shaping and tunable metasurface design on the physical layer and ML techniques on the processing layer.

description: An important test for models of galaxy formation lies in the metallicity distribution functions (MDFs) of spheroid stars and their globular clusters (GCs).We have compared the MDFs obtained from spectroscopy of the GCs and the star-by-star photometry of red giants in the nearby elliptical NGC 5128, with the predictions of a semi-analytic galaxy formation model. We have selected model ellipticals comparable in luminosity and environment to NGC 5128, and derived their MDFs. A direct comparison between models and data shows that the MDFs are qualitatively similar, both have stellar components which are predominantly metal-rich (0.8Z), with a small fraction of metal-poor stars extending down to 0.002Z. The model MDFs show only small variations, whether they are brightest cluster galaxies or low luminosity group ellipticals. Our comparison also reveals that these model MDFs harbour a greater fraction of stars above solar metallicity than the observations, producing generally more metal-rich (by 0.1 dex) MDFs. One possibility is that the outer-bulge observations are missing some of the highest metallicity stars. We find good agreement between the model and observed GC MDFs, provided that the metal-poor GC formation is halted early in the model. Under this proviso, both the models and data are bimodal with peaks at 0.1Z and Z, and cover similar metallicity ranges. This broad agreement for the stars and GCs suggests that the bulk of the stellar population in NGC 5128 may have been built up in a hierarchical fashion, involving both quiescent and merger-induced star formation. The existence of age structure amongst the metal-rich GCs needs to be tested against high-quality data for this galaxy.

description: In the present work we investigate the stability of the k-essence models allowing upto quadratic terms of the kinetic energy. The system of field equations is written as an autonomous system in terms of dimensionless variables and the stability criteria of the equilibria have been extensively investigated. The results strongly indicate that cosmologically consistent models dynamically evolve towards the quintessence model, a stable solution with a canonical form of the dark energy.

description: The reduced proper motion diagram (RPMD) for a complete sample of faint stars with high accuracy proper motions in the North Galactic Pole field SA57 is investigated. Eight stars with very large reduced proper motions are identified as faint white dwarf candidates. We discriminate these white dwarf candidates from the several times more numerous QSOs based on proper motion and variability. We discuss the implausibility that these stars could be any kind of survey contaminant. If {\it bona fide} white dwarfs, the eight candidates found here represent a portion of the white dwarf population hitherto uninvestigated by previous surveys by virtue of the faint magnitudes and low proper motions. The newly discovered stars suggest a disk white dwarf scaleheight larger than the values of 250-350 pc typically assumed in assessments of the local white dwarf density. Both a and a more complex maximum likelihood analysis of the spatial distribution of our likely thin disk white dwarfs yield scaleheights of 400-600 pc while at the same time give a reasonable match to the local white dwarf volume density found in other surveys. Our results could have interesting implications for white dwarfs as potential MACHO objects. We can place some direct constraints (albeit weak ones) on the contribution of halo white dwarfs to the dark matter of the Galaxy. Moreover, the elevated scale height that we measure for the thin disk could alter the interpretation of microlensing results to the extent of making white dwarfs untenable as the dominant MACHO contributor.

Encoded Universality for Generalized Anisotropic Exchange Hamiltonians

description: We derive an encoded universality representation for a generalized anisotropic exchange Hamiltonian that contains cross-product terms in addition to the usual two-particle exchange terms. The recently developed algebraic approach is used to show that the minimal universality-generating encodings of one logical qubit are based on three physical qubits. We show how to generate both single- and two-qubit operations on the logical qubits, using suitably timed conjugating operations derived from analysis of the commutator algebra. The timing of the operations is seen to be crucial in allowing simplification of the gate sequences for the generalized Hamiltonian to forms similar to that derived previously for the symmetric (XY) anisotropic exchange Hamiltonian. The total number of operations needed for a controlled-Z gate up to local transformations is five. A scalable architecture is proposed.

description: Quantum information technology based on solid state qubits has created much interest in converting quantum states from the microwave to the optical domain. Optical photons, unlike microwave photons, can be transmitted by fiber, making them suitable for long distance quantum communication. Moreover, the optical domain offers access to a large set of very well developed quantum optical tools, such as highly efficient single-photon detectors and long-lived quantum memories. For a high fidelity microwave to optical transducer, efficient conversion at single photon level and low added noise is needed. Currently, the most promising approaches to build such systems are based on second order nonlinear phenomena such as optomechanical and electro-optic interactions. Alternative approaches, although not yet as efficient, include magneto-optical coupling and schemes based on isolated quantum systems like atoms, ions or quantum dots. In this Progress Report, we provide the necessary theoretical foundations for the most important microwave-to-optical conversion experiments, describe their implementations and discuss current limitations and future prospects.

description: The identification of precipitation regimes is important for many purposes such as agricultural planning, water resource management, and return period estimation. Since precipitation and other related meteorological data typically exhibit spatial dependency and different characteristics at different time scales, clustering such data presents unique challenges. In this paper, we develop a flexible model-based approach to cluster multi-scale spatial functional data to address such problems. The underlying clustering model is a functional linear model , and the cluster memberships are assumed to be a realization from a Markov random field with geographic covariates. The methodology is applied to a precipitation data from China to identify precipitation regimes.

description: We study the quantum open system evolution described by a Gorini-Kossakowski-Sudarshan-Lindblad generator with creation and annihilation operators arising in Fock representations of the $sl_2$ Lie algebra. We show that any initial density matrix evolves to a fully supported density matrix and converges towards a unique equilibrium state. We show that the convergence is exponentially fast and we exactly compute the rate for a wide range of parameters. We also discuss the connection with the two-photon absorption and emission process.

description: Here we report the structural and electronic properties of CeAu$_{2}$Bi, a new heavy-fermion compound crystallizing in a nonsymmorphic hexagonal structure ($P63/mmc$). The Ce$^{3+}$ ions form a triangular lattice which orders antiferromagnetically below $T_{N} = 3.1$~K with a magnetic hard axis along the c-axis. Under applied pressure, $T_{N}$ increases linearly at a rate of $0.07$~K/kbar, indicating that the Ce $f$-electrons are fairly localized. In fact, heat capacity measurements provide an estimate of 150(10) mJ/mol.K$^{2}$ for the Sommerfeld coefficient. The crystal-field scheme obtained from our thermodynamic data points to a ground state with dominantly $|j_{z}=\pm1/2\rangle$ character, which commonly occurs in systems with a hard c-axis. Finally, electronic band structure calculations and symmetry analysis in $k$-space reveal that CeAu$_{2}$Bi hosts symmetry-protected crossings at $k_{z} = π$ in the paramagnetic state

description: If an economist were asked to choose one aspect of a country's economy which could best illustrate the quality of its economic organisation and problems he would, at some stage, consider reviewing one of the largest single industries in the country. Whether, or not he finally settled on a large industry would depend on how deeply a study of it it would reveal and explain the characteristics of the economy in general. If the country was developing along new lines he would prefer a new or expanding industry; if he felt the economy was dominated by the state of the balance of payments he would desire a strong relation between foreign exchange and the level of activity in the industry of his choice.

Spectroscopic Study of IRAS 19285+0517(PDS 100): A Rapidly Rotating Li-Rich K Giant

description: We report on photometry and high-resolution spectroscopy for IRAS 19285+0517. The spectral energy distribution based on visible and near-IR photometry and far-IR fluxes shows that the star is surrounded by dust at a temperature of $T_{\rm {d}}$ $\sim$ 250 K. Spectral line analysis shows that the star is a K giant with a projected rotational velocity $v sin i$ = 9 $\pm$ 2 km s$^{-1}$. We determined the atmospheric parameters: $T_{\rm {eff}}$ = 4500 K, log $g$ = 2.5, $ξ_{t}$ = 1.5 km s$^{-1}$, and [Fe/H] = 0.14 dex. The LTE abundance analysis shows that the star is Li-rich (log $ε$(Li) = 2.5$\pm$0.15), but with essentially normal C, N, and O, and metal abundances. Spectral synthesis of molecular CN lines yields the carbon isotopic ratio $^{12}$C/$^{13}$C = 9 $\pm$3, a signature of post-main sequence evolution and dredge-up on the RGB. Analysis of the Li resonance line at 6707 Åfor different ratios $^{6}$Li/$^{7}$Li shows that the Li profile can be fitted best with a predicted profile for pure $^{7}$Li. Far-IR excess, large Li abundance, and rapid rotation suggest that a planet has been swallowed or, perhaps, that an instability in the RGB outer layers triggered a sudden enrichment of Li and caused mass-loss.
