description: We measure the autocorrelation function of galaxies in the IRAS Point Source Catalogue galaxy redshift (PSCz) survey and investigate its dependence on the far-infrared colour and absolute luminosity of the galaxies. We find that the PSCz survey correlation function can be modelled out to a scale of 10 h^{-1}Mpc as a power law of slope 1.30 +/- 0.04 and correlation length 4.77 +/- 0.20. At a scale of 75 h^{-1}Mpc we find the value of J_3 to be 1500 +/- 400. We also find that galaxies with cooler dust temperatures, are more strongly clustered than warmer galaxies. Splitting the survey into three colour subsamples, we find that, between 1 and 10 h^{-1}Mpc, the ratio of the correlation function is factor of 1.5 higher for the cooler galaxies compared to the hotter galaxies. This is consistent with the suggestion that hotter galaxies have higher star-formation rates, and correspond to later-type galaxies which are less clustered than earlier types. Using volume limited sub-samples, we find a weak variation of the correlation function as a function of absolute luminosity, in the sense that more luminous galaxies are less clustered than fainter galaxies. The trend is consistent with the colour dependence of the correlation function and the observed colour-luminosity correlation, but the large uncertainties mean that it has a low statistical significance.

description: Playing repeated matrix games (RMG) while maximizing the cumulative returns is a basic method to evaluate multi-agent learning (MAL) algorithms. Previous work has shown that $UCB$, $M3$, $S$ or $Exp3$ algorithms have good behaviours on average in RMG. Besides, hedging algorithms have been shown to be effective on prediction problems. An hedging algorithm is made up with a top-level algorithm and a set of basic algorithms. To make its decision, an hedging algorithm uses its top-level algorithm to choose a basic algorithm, and the chosen algorithm makes the decision. This paper experimentally shows that well-selected hedging algorithms are better on average than all previous MAL algorithms on the task of playing RMG against various players. $S$ is a very good top-level algorithm, and $UCB$ and $M3$ are very good basic algorithms. Furthermore, two-level hedging algorithms are more effective than one-level hedging algorithms, and three levels are not better than two levels.

description: Bulk samples of La2.3-xYxCa0.7Mn2O7, x=0,0.3,0.5, with layered perovskite structure have been synthesized and investigated with respect to their electrical, electronic and magnetic properties. It is found that La1.8Y0.5Ca0.7Mn2O7 has tetragonal structure and is a metallic ferromagnet with a magnetic transition temperature of 170 K. The compound shows metallic behavior below 140 K and has a large magnetoresistance (MR) Delta-rho/rho(0)~94% at 100 K at 34 kOe. For x=0 and 0.3 the structure is monoclinic with a suppression of metallicity. For x=0 the material is an ferromagnetic insulator. We observed a large increase in the coefficient of the linear term in specific heat with decreasing x. As far as we are aware, this is the first report of an electron doped manganite showing metal-insulator transition and ferromagnetism.

description: This paper presents a cross-calibrated catalog of Hipparcos and Gaia astrometry to enable their use in measuring changes in proper motion, i.e., accelerations in the plane of the sky. The final catalog adopts the reference frame of the second Gaia data release (DR2) and locally cross-calibrates both the scaled Hipparcos-Gaia DR2 positional differences and the Hipparcos proper motions themselves to this frame. This gives three nearly independent proper motion measurements per star, with the scaled positional difference usually being the most precise. We find that a linear combination of the two Hipparcos reductions is superior to either reduction on its own, and address error inflation for both Hipparcos and Gaia DR2. Our adopted error inflation is additive (in quadrature) for Hipparcos and multiplicative for Gaia. We provide the covariance matrices along with the central epochs of all measurements. Our final proper motion differences are accurately Gaussian with the appropriate variances, and are suitable for acceleration measurements and orbit fitting. The catalog is constructed with an eye toward completeness; it contains nearly 98\% of the Hipparcos stars. It also includes a handful of spurious entries and a few stars with poor Hipparcos reductions that the user must vet by hand. Statistical distributions of accelerations derived from this catalog should be interpreted with caution.

description: Polyhydroxyalkanoates are gaining importance due to their biodegradable nature and close analogy to plastics. Polyhydroxybutyrate (PHB) is the most widely used bioplastic from polyalkanoate family, which is produced by a legion of bacterial species via phbCAB operon encoding β-ketothiolase (PhaA), NADPH-dependent acetoacetyl-coenzyme A (acetoacetyl-CoA) reductase (PhaB) and polyhydroxyalkanoate synthase (PhaC). Augmentation in the activity of these enzymes is promising for increased PHB production which is achieved by enzyme engineering strategies including non-structural and structural approaches. Our study is deployed on directed evolution-based experimentally reported mutants of PhaB enzyme with increased efficiency due to impact on critical structural factors. We have analyzed and compared the native PhaB with two of its variants Q47L and T173S in complex with their cofactor i.e. NADPH as well as the substrate i.e. acetoacetyl-CoA, via long range molecular dynamics simulations. Interaction profile, MMPBSA, essential dynamics, and free energy landscape analysis revealed that the enzyme efficiency is critically affected by cofactor interactions. It was also observed that mutants have higher equilibrium constant with lesser but optimal affinity for substrate and cofactor than the wild type, which might be the reason for increased efficiency of the mutants via enhanced substrate and cofactor exchange rate. Our study provides insights into the cofactor and substrate binding affinities to PhaB enzyme at atomistic level, which will facilitate designing of highly efficient PhaB enzymes for increased PHB production.

Constraints on properties of the protoplanetary disks around UX Ori and CQ Tau

description: We present Very Large Array observations of the intermediate mass pre-main-sequence stars UX Ori and CQ Tau at 7mm, 3.6cm, and 6cm. These stars are members of the UX Ori variability class, where the origin of optical variability is thought to derive from inhomogeneities in circumstellar disks. Both stars are detected at 7mm but not at longer wavelengths, which confirms that the millimeter emission is dominated by dust. The UX Ori system exhibits a remarkably flat spectral index in the millimeter range, with alpha_mm 2 (F_nu nu^alpha_mm). Two different disk models can reproduce this property: i) a physically small disk with optically thick emission, truncated at a radius about 30 AU, or ii) a massive (~0.3-1 Msun) disk mainly composed of dust particles grown to radii of 10cm (``pebbles''). The observations do not spatially resolve the 7mm emission. We discuss implications of these two models and suggest observational tests that will discriminate between them. The CQ Tau system exhibits a spectral index in the millimeter range of alpha_mm 2.6, consistent with values commonly found for disks around pre-main-sequence stars. The observations marginally resolve the 7mm emission as an elongated structure with full width at half maximum of 2.4"x1.1" (240x110 AU at 100pc distance). The size and inclination of ~63 degrees (implied by circular symmetry) are consistent with flared disk models previously suggested to explain the optical colors and polarization properties.

description: We consider the Rayleigh--Bénard problem for the three--dimensional Boussinesq system for the micropolar fluid. We introduce the notion of the multivalued eventual semiflow and prove the existence of the two-space global attractor $\mathcal{A}^K$ corresponding to weak solutions, for every micropolar parameter $K\geq 0$ denoting the deviation of the considered system from the classical Rayleigh--Bénard problem for the Newtonian fluid. We prove that for every $K$ the attractor $\mathcal{A}^K$ is the smallest compact, attracting, and invariant set. Moreover, the semiflow restricted to this attractor is single-valued and governed by strong solutions. Further, we prove that the global attractors $\mathcal{A}^K$ converge to $\mathcal{A}^0$ upper semicontinuously in Kuratowski sense as $K\to 0$, and that the projection of $\mathcal{A}^0$ on the restricted phase space corresponding to the classical Rayleigh--Bénard problem is the global attractor for the latter problem, having the invariance property. These results are established under the assumption that the Prandtl number is relatively large with respect to the Rayleigh number.

description: This thesis attempts to account for the patterns of land utilization and settlement in Upper Mandailing, Sumatra, an area of 956 sq. km. occupied for several hundred years by rice farmers of Proto-Malayan stock. Upper Mandailing can be described as mountainous, Muslim and patrilineal. These important features also distinguish it from neighbouring areas. It is situated on the mountain backbone between Menangkabau (in the Province of Middle Sumatra) to the south and Lower Mandailing to the north. The political boundary between Upper and Lower Mandailing runs along the sharp crest of the Si Hite-Sordang Cuesta. Prom Upper Mandailing, Lower Mandailing is reached by passing over the extensive rolling lava plain at the foot of the active volcano, Sorik Merapi. Upper Mandailing and Lower Mandailing possess the same adat law, that is, they have the same customs and traditions. The people have been Muslim since the early part of the nineteenth century. In both areas society was formerly differentiated into slaves, commoners of a number of clans, and members of the dominant land-owning clan which supplied the political leaders (radja). In most of Upper Mandailing Lubis was the dominant clan and in Lower Mandailing, Nasution. All clans were exogamous and Nasution and Lubis frequently intermarried. Today society in both areas is nominally egalitarian and anyone can own land; but hereditary titles which imply wealth are important. Clan exogamy is still largely adhered to.

description: We construct the most generic Hamiltonian of the $8Pmmn$ structure of borophene sheet in presence of spin-orbit, as well as background electric and magnetic fields. In addition to spin and valley Hall effects, this structure offers a framework to conveniently manipulate the resulting "tilt" of the Dirac equation by applying appropriate electric fields. Therefore, the tilt can be made space-, as well as time-dependent. The border separating the low-field region with under-tilted Dirac fermions from the high-field region with over-tilted Dirac fermions will correspond to a black-hole horizon. In this way, space-time dependent electric fields can be used to design the metric of the resulting space-time felt by electrons and holes satisfying the tilted Dirac equation. Our platform offers a way to generate analogues of gravitational waves by electric fields (instead of mass sources) which can be detected in solid state spectroscopies as waves of enhanced superconducting correlations.

The spread of settlement in the original nineteen counties of New South Wales: 1788-1829 : an historical geography

description: The thesis describes the salient physical features of the part of New South Wales included in the original nineteen counties which were proclaimed in 1829 and then discusses the settlement of the Cumberland Plain, the area in the immediate vicinity of Sydney. It shows how in the settlement of the plain variations in the quality of the soil led to the establishment of scattered clusters of farms, and how in the years 1810 to 1821 a series of droughts and caterpillar plagues made it necessary for the colony’s stockowners to find new areas in which to graze their cattle-and sheep. A reduction of the plain’s stock carrying capacity rather than a shortage of land was the reason for the outward movement of settlers during these years. A general account of the spread of settlement from the Cumberland Plain over the encircling sandstone plateau into the surrounding areas of the Hunter Valley, western uplands, southern tableland and Illawarra-Shoalhaven coastal plain is then given, and the circumstances and policies which led to the imposition of "limits of location" in 1826 and 1829 are discussed. Pour chapters are then devoted to a more detailed discussion of the way in which physical features,governmental policy, and economic expediency affected their settlement. The general conclusions drawn from the study are that during the period 1788 to 1829, the pattern of settlement was influenced to a large degree not only by the nature of the country (including its periodic visitation of drought and caterpillar plague) , but also by its governor’s policies, and that in each of the regions considered in detail differences in topography, climate and soil, in the class of settler who occupied them, and in the amount of government control of settlement, produced four quite distinctive types of land utilization and frontier society. Neither environmental nor human factors alone determined the pattern and nature of the settlement of the nineteen counties, and the changing relations (both in place and time) of these two sets of factors thus resulted in marked regional differentiations, a fact which rarely emerges in the generalised picture of early settlement in the standard histories.

description: Monolithic NbB2, NbB2-SiC, and NbB2-SiC-GNP samples were produced by spark plasma sintering (SPS), and the effects of additives on the mechanical and thermal properties, microstructures, and oxidation behavior of the samples were investigated. The addition of SiC up to 30 vol% decreased the Vickers hardness of the binary composites due to microcrack formation. The fracture toughness and oxidation resistance of NbB2 were improved with the incorporation of SiC. Fracture toughness was higher for all the composites in comparison to monolithic NbB2, moreover the highest value of ~5.2 MPa·m1/2 exhibited by 3 vol% GNP-containing composite. A strong interface and homogeneous distribution of GNPs enhanced the thermal transfer properties and improved the oxidation resistance of selected NbB2-SiC ceramics in oxidation studies at 1200°C. A combination of high mechanical properties, high thermal conductivity, and low mass gain was achieved for the NbB2-SiC-GNP samples with 1 and 3 vol% GNPs.

The operation of the maxim "what cannot be done directly cannot be done indirectly" in public law
Creators: name: Singh, D. K
Publisher: name: The Australian National University
Year: 1961
Subjects: public law

description: This thesis is concerned with a formal problem which arieses in the judicial review of laws limiting the range of governmental powers. Vast problems of a legal nature are posed in the observance of limitations imposed on governmental powers. Presumably the solution must be found in the working of judicial machinery - courts being the watchdog of consitutional provisions; no-one would deny the role played by courts in the growth and develpment of consitutionalism. The judicial practice involves a set of "unwritten" rules for the guidance of courts in the undersatning (or interpretation) of "written" laws, including written consitutions, One of such rules is the observance of "good faith" in the exercise of governmental powers, and it is implied in the maxim "What cannot be done directly cannot be done indirectly." This study is confined to English language systems, and to predominantly English common-law systems; South Africa is included, but the South African cases considered are also mainly English common-law in their ideological background. Nevertheless, the range of constitutional and administrative systems is reasonably wide. In casual conversation, even among lawyers, one of ten gets an impression that the maxim has not much force in limiting the acts or actions of governments, since so many schemes, which may be of great consequence politically or otherwise, have received the approval of courts even though they were designed to achieve something that was not permissible, or have been carried through without judicial challenge. Here an attempt is made to examine the implications and intricacies in the operation of the maxim and assess its importance or usefulness as a rule of constitutional interpretation, It is a selective, not an exhaustive, study. The aim is to focus attention on the problems emphasised here and stimulate further detailed examination from a similar point of view. The discussion is mainly on the level of legal formalism, and no attempt is made to analyse the impact of social, economic or political factors on judicial practice.

description: Density-based clustering relies on the idea of linking groups to some specific features of the probability distribution underlying the data. The reference to a true, yet unknown, population structure allows to frame the clustering problem in a standard inferential setting, where the concept of ideal population clustering is defined as the partition induced by the true density function. The nonparametric formulation of this approach, known as modal clustering, draws a correspondence between the groups and the domains of attraction of the density modes. Operationally, a nonparametric density estimate is required and a proper selection of the amount of smoothing, governing the shape of the density and hence possibly the modal structure, is crucial to identify the final partition. In this work, we address the issue of density estimation for modal clustering from an asymptotic perspective. A natural and easy to interpret metric to measure the distance between density-based partitions is discussed, its asymptotic approximation explored, and employed to study the problem of bandwidth selection for nonparametric modal clustering.

description: This tutorial gives an elementary and self-contained review of abelian bosonization in 1 dimension in a system of finite size $L$, following and simplifying Haldane's constructive approach. As a non-trivial application, we rigorously resolve (following Furusaki) a recent controversy regarding the tunneling density of states, $ρ_{dos} (ω)$, at the site of an impurity in a Tomonaga-Luttinger liquid: we use finite-size refermionization to show exactly that for g=1/2 its asymptotic low-energy behavior is $ρ_{dos}(ω) \sim ω$. This agrees with the results of Fabrizio & Gogolin and of Furusaki, but not with those of Oreg and Finkel'stein (probably because we capture effects not included in their mean-field treatment of the Coulomb gas that they obtained by an exact mapping; their treatment of anti-commutation relations in this mapping is correct, however, contrary to recent suggestions in the literature). --- The tutorial is addressed to readers unfamiliar with bosonization, or for those interested in seeing ``all the details'' explicitly; it requires knowledge of second quantization only, not of field theory. At the same time, we hope that experts too might find useful our explicit treatment of certain subtleties -- these include the proper treatment of the so-called Klein factors that act as fermion-number ladder operators (and also ensure the anti-commutation of different species of fermion fields), the retention of terms of order 1/L, and a novel, rigorous formulation of finite-size refermionization of both $e^{-i Φ(x)}$ and the boson field $Φ(x)$ itself.
description: Revtex, 70 pages. Changes: Regarding the controversial tunneling density of states at an impurity in a g=1/2 Luttinger liquid, we (1) give a new, more explicit calculation, (2) show that contrary to recent suggestions (including our own), Oreg and Finkel'stein treat fermionic anticommutation relations CORRECTLY (see Appendix K), but (3) suggest that their MEAN-FIELD treatment of their Coulomb gas may not be sufficiently accurate

description: In the present scenario rate of utilization of electrical energy is continuously increasing, to preserve the non-renewable energy resources, efficient consumption of electrical energy is one of the most important needs of this era. Smart Energy Meter (SEM) plays a vital role in efficient use of electrical energy in consumer premises. Accuracy in the measurement of current is one of the key factors to be considered while measuring energy consumption. This paper introduces Arduino based low cost single-phase SEM and proposes a linear regression based technique for accurate measurement of current. The proposed current measurement approach gives accurate measurement for linear as well as highly non-linear loads. The SEM built in the laboratory has data transfer capability and also embedded with Demand Response (DR) feature. Block Rate Tariff structure used by Tamil Nadu Generation and Distribution Company is considered to incorporate DR that warns the consumers whenever their energy consumption reaches the boundary of a block.

description: Moving metasurfaces support guided waves exhibiting unusual optical properties, including strong anisotropy, nonreciprocity, and hyperbolic dispersion. However, for these phenomena to be noticeable, high speeds are typically required, challenging their practical implementation. Here, we show a viable route towards the realization of one-way hyperbolic propagation in metasurfaces placed synthetically in motion through traveling-wave space-time modulation. In addition to non-reciprocal hyperbolic propagation, the proposed time-modulation scheme induces additional exotic opportunities for nanophotonic systems, such as efficient nonreciprocal frequency conversion and mode transfer.

description: No major country in the world is as reliant on migrant remittance flows as is the Philippines, with some 8-11 million workers overseas sending $17 billion back home each year. As important as these flows are to the Philippine economy, the export of labor has never been part of a coherent development strategy. At least 13 major government agencies are involved in matters pertaining to overseas Filipino workers, but the result is more of a patchwork of overlapping roles than a systematic regulatory regime. My thesis examines relations between these agencies and the approximately 1,500 recruitment agencies that are the key private-sector actors in facilitating overseas migration from the Philippines. Despite the importance of these agencies, no previous research has examined their role, their associational ties, or the nature of their relations with a range of government actors. Theoretically, my research contributes to debates within political economy on what roles the private sector and government have in pursuing and achieving national economic development objectives. Beyond this primary contribution, my research also provides insights into debates on alternative development strategies in developing states, the politics of international labor migration, and bilateral labor relations between states. The research for my thesis was gathered primarily across five months of fieldwork in the Philippines. While there, I was able to utilize multiple methods of investigation including interviews with politicians, bureaucrats, NGOs, business leaders, and international organizations as well as significant archival research. My thesis topic intersects with many research areas, including not only the politics of development and government-business relations but also state-society relations, structures of governance, foreign policy making, and international diplomacy.

description: We introduce the notion of `order-$k$ non-abelian exclusion statistics'. We derive the associated thermodynamic equations by employing the Thermodynamic Bethe Ansatz for specific non-diagonal scattering matrices. We make contact with results obtained by different methods and we point out connections with `fermionic sum formulas' for characters in a Conformal Field Theory. As an application, we derive thermodynamic distribution functions for quasi-holes over a class of non-abelian quantum Hall states recently proposed by Read and Rezayi.

description: Quantum steering is a kind of quantum correlations stronger than entanglement but weaker than Bell-nonlocality. In an optomechanical system pumped by squeezed light and driven in the red sideband, we study-under thermal effects-stationary Gaussian steering and its asymmetry of two mechanical modes. In the resolved sideband regime using experimentally feasible parameters, we show that Gaussian steering can be created by quantum fluctuations transfer from the squeezed light to the two mechanical modes. Moreover, one-way steering can be observed by controlling the squeezing degree or the environmental temperature. A comparative study between Gaussian steering and Gaussian Rényi-2 entanglement of the two considered modes shows on one hand that both steering and entanglement suffer from a sudden death-like phenomenon with early vanishing of steering in various circumstances. On the other hand, steering is found stronger than entanglement, however, remains constantly upper bounded by Gaussian Rényi-2 entanglement, and decays rapidly to zero under thermal noise.

Abstract:

Hyper-Kamiokande, the next generation of water Cherenkov neutrino detector, will take a unique role in neutrino physics and astrophysics. Its construction started in 2020 and the experiment is expected to start operations in 2027. It will serve as a far detector of a long-baseline neutrino experiment and an observatory for astrophysical neutrinos and rare decays. The baseline design has a fiducial volume 8 times the size of its predecessor, Super-Kamiokande, and is instrumented with new photosensors that offer significant performance improvements. Combined with the upgraded J-PARC neutrino beam produced 295 km away, as well as a near detector suite, Hyper-Kamiokande will be able to measure neutrino oscillation with unprecedented statistical precision, enabling the determination of the CP violation and the precise measurement of atmospheric neutrino oscillation. The large detector size will greatly improve the study of astrophysical neutrinos, such as supernova burst, supernova relicneutrinos, and solar neutrinos. It will also enable the search for proton decays in a variety of final-state decays. In this talk, an overview of the Hyper-Kamiokande experiment will be provided, highlighting its significance in the neutrino physics and astrophysics field, and its construction status will be presented.

Mushroom-Shaped Structures as Tracers of Buoyant Flow in the Galactic Disk

description: Recent HI emission observations of the Southern Galactic hemisphere have revealed a mushroom-like structure extending from z=-70 to -450 pc, composed of a stem and a cap. Similar structures occur in three-dimensional simulations of a dynamic galactic disk driven by isolated and clustered supernovae. Using these simulations, we show that hot gas in the Galactic disk that is not evacuated through chimneys expands into the cooler gas of the thick disk, forming mushroom-shaped structures. This new class of objects traces buoyant flow of hot gas into the thick disk.

Dynamic facilitation theory: A statistical mechanics approach to dynamic arrest

description: The modeling of supercooled liquids approaching dynamic arrest has a long tradition, which is documented through a plethora of competing theoretical approaches. Here, we review the modeling of supercooled liquids in terms of dynamic "defects", also called excitations or soft spots, that are able to sustain motion. To this end, we consider a minimal statistical mechanics description in terms of active regions with the order parameter related to their typical size. This is the basis for both Adam-Gibbs and dynamical facilitation theory, which differ in their relaxation mechanism as the liquid is cooled: collective motion of more and more particles vs. concerted hierarchical motion over larger and larger length scales. For the latter, dynamic arrest is possible without a growing static correlation length, and we sketch the derivation of a key result: the parabolic law for the structural relaxation time. We critically discuss claims in favor of a growing static length and argue that the resulting scenarios for pinning and dielectric relaxation are in fact compatible with dynamic facilitation.
Transversely Driven Charge Density Waves and Striped Phases of High-T$_c$ Superconductors: The Current Effect Transistor

description: We show that a normal (single particle) current density $J_x$ {\em transverse} to the ordering wavevector $2k_F{\bf\hat{z}}$ of a charge density wave (CDW) has dramatic effects both above and {\em below} the CDW depinning transition. It exponentially (in $J_x$) enhances CDW correlations, and exponentially suppresses the longitudinal depinning field. The intermediate longitudinal I-V relation also changes, acquiring a {\em linear} regime. We propose a novel ``current effect transistor'' whose CDW channel is turned on by a transverse current. Our results also have important implications for the recently proposed ``striped phase'' of the high-T$_c$ superconductors.

Elimination of Clock Jitter Noise in Spaceborn Laser Interferometers

description: Space gravitational wave detectors employing laser interferometry between free-flying spacecraft differ in many ways from their laboratory counterparts. Among these differences is the fact that, in space, the end-masses will be moving relative to each other. This creates a problem by inducing a Doppler shift between the incoming and outgoing frequencies. The resulting beat frequency is so high that its phase cannot be read to sufficient accuracy when referenced to state-of-the-art space-qualified clocks. This is the problem that is addressed in this paper. We introduce a set of time-domain algorithms in which the effects of clock jitter are exactly canceled. The method employs the two-color laser approach that has been previously proposed, but avoids the singularities that arise in the previous frequency-domain algorithms. In addition, several practical aspects of the laser and clock noise cancellation schemes are addressed.

description: This document summarises main points of the presentation given at the second GRECO consortium meeting in Sofia (Bulgaria) on 21 May 2019. In the following, it will highlight gender issues from different point of views - being potentially useful for the development of the GRECO research project. GRECO aims, among others, to implement Responsible Research and Innovation practices -including gender. After an introduction on the meaning of sex and gender analysis and their importance in research, the suggestion is to consider gender as a key aspect in research. Gender refers to research staff, research and innovation methods, impact of research and innovation. Key readings on gender in the energy sector, derived from current studies, are provided to frame the scenario of the project. The conclusive invitation - in the form of open questions - is to keep and strengthen the application of gender issues to GRECO.
