description: Η παρούσα μελέτη αφορά στην κατασκευή της ταυτότητας του/της Κρητικού/ιάς μέσα από τέσσερα ιστορικά μυθιστορήματα. Προσεγγίζονται οι έννοιες της ταυτότητας και της ετερότητας, της διαφορετικότητας και της διαπολιτισμικής κοινοτικής συνύπαρξης στο νησί της Κρήτης, καθώς επίσης και οι έννοιες του έθνους, της εθνικότητας και του εθνικισμού ως παράμετροι που συντελούν στη διάσπαση της συνύπαρξης αυτής. Αναλύεται για τους σκοπούς αυτούς η Θεωρία της Λογοτεχνίας και πραγματοποιείται υποκειμενική ανάλυση αφηγήσεων τριών συγγραφέων που κατάγονται από την Κρήτη (Μάρω Δούκα, Ρέα Γαλανάκη, Σαμπά Αλτίνσαϊ), μέσα στο ιδιάζον ιστορικό πλαίσιο με τις ιδιαίτερες κοινωνικές συνθήκες. Προκύπτουν μέσω της ανάλυσης συμπεράσματα που αφορούν στη συλλογική ταυτότητα του/της Κρητικού/ιάς αλλά και στις ατομικές ταυτότητες (έμφυλη, κοινωνική, προσωπική) των χαρακτήρων των μυθιστορημάτων.
description: This study involves the construction of the identity of the Cretan through four historical novels. The concepts of identity, diversity and intercultural communal coexistence on the island of Crete, as well as the concepts of nation, nationality and nationalism as factors that contribute to the breakdown of this coexistence are being approached. For these purposes the Theory of Literature is being analysed and subjective analysis is performed, derived from the narratives of three authors, originating from Crete (Maro Duka, Rea Galanaki, Saba Altinsai). The significant historical context as well as the particular social conditions are being considered. Through the analysis the findings which are obtained are related to the collective identity of the Cretan (resident or not), as well as the individual identities (gender, social, personal) of the novels' characters.

description: Interactive documentaries offer new possibilities in the fields of public participation and the organization and presentation of audiovisual storytelling. The abovementioned fields, in combination with today’s possibilities of networking and sharing media content, can be used to further the objectives of peace-building. This paper addresses the role of the media and specifically that of interactive documentaries in the process of peace-building. Furthermore, this thesis examines the interactive documentary as a medium of communication, scrutinizes the contribution of the media to peace-building and specifically analyzes the emerging practice of peace journalism as a suitable approach to the latter. By doing so, it attempts to explore the ways in which the use of interactive documentary can be put in the service of peace journalism. The paper concludes with the presentation of an early-stage, original interactive documentary, discussed as an implementation of peace journalism and followed by suggestions of ways in which the interactive documentary can be evaluated in the context of peace-building.

description: A systematic study of the impact of annealing on the electronic properties of single InAs/GaAs quantum dots (QDs) is presented. Single QD cathodoluminescence spectra are recorded to trace the evolution of one and the same QD over several steps of annealing. A substantial reduction of the excitonic fine-structure splitting upon annealing is observed. In addition, the binding energies of different excitonic complexes change dramatically. The results are compared to model calculations within eight-band k.p theory and the configuration interaction method, suggesting a change of electron and hole wave function shape and relative position.

description: The rise of flexible electronics calls for cost-effective and scalable batteries with good mechanical and electrochemical performance. In this work, we developed printable, polymer-based AgO-Zn batteries that feature flexibility, rechargeability, high areal capacity, and low impedance. Using elastomeric substrate and binders, the current collectors, electrodes, and separators can be easily screen-printed layer-by-layer and vacuum-sealed in a stacked configuration. The batteries are customizable in sizes and capacities, with the highest obtained areal capacity of 54 mAh/cm2 for primary applications. Advanced micro-CT and EIS were used to characterize the battery, whose mechanical stability was tested with repeated twisting and bending. The batteries were used to power a flexible E-ink display system that requires a high-current drain and exhibited superior performance than commercial coin-cell batteries. The developed battery presents a practical solution for powering a wide range of electronics and holds major implications for the future development of practical and high-performance flexible batteries.

description: Controllable artificial pinning is indispensable in numerous domain-wall (DW) devices, such as memory, sensor, logic gate, and neuromorphic computing hardware. The high-accuracy determination of the effective spring constant of the pinning potential, however, remains challenging, because the extrinsic pinning is often mixed up with intrinsic ones caused by materials defects and randomness. Here, we study the collective dynamics of interacting DWs in a racetrack with pinning sites of alternate distances. By mapping the governing equations of DW motion to the Su-Schrieffer-Heeger model and evaluating the quantized Zak phase, we predict two topologically distinct phases in the racetrack. Robust edge state emerges at either one or both ends depending on the parity of the DW number and the ratio of alternating intersite lengths. We show that the in-gap DW oscillation frequency has a fixed value which depends only on the geometrical shape of the pinning notch, and is insensitive to device imperfections and inhomogeneities. We propose to accurately quantify the spring coefficient that equals the square of the robust DW frequency multiplied by its constant mass. Our findings suggest as well that the DW racetrack is an ideal platform to study the topological phase transition.

description: Se ci si interroga sui risultati raggiunti dallo studio della cultura ortodossa della Rus’ moscovita negli ultimi 25 anni, si può concludere che l’esito più rilevante delle ricerche condotte in questo campo è stato forse la scoperta della rilevanza delle “differenze tipologiche” fra la cultura bizantino-ortodossa della Rus’ e la cultura cristiana dell’Occidente “latino”. Tuttavia, nell’ambito di un breve articolo sulle acquisizioni del lavoro degli storici, dovremo ovviamente limitarci a qualche “sondaggio” per mettere in evidenza i cambiamenti verificatisi nella storiografia nell’ultimo quarto di secolo. Quanto segue è appunto un sondaggio sui rapporti fra la cultura della Rus’ moscovita e il mondo islamico.

description: Monolayer transition metal dichalcogenide semiconductors host strongly bound two-dimensional excitonic complexes, and form an excellent platform for probing many-body physics through manipulation of Coulomb interaction. Quantum confined Stark effect is one of the routes to dynamically tune the emission line of these excitonic complexes. In this work, using a high quality graphene/hBN/WS$_2$/hBN/Au vertical heterojunction, we demonstrate for the first time, an out-of-plane electric field driven change in the sign of the Stark shift from blue to red for four different excitonic species, namely, the neutral exciton, the charged exciton (trion), the charged biexciton, and the defect-bound exciton. Such universal non-monotonic Stark shift with electric field arises from a competition between the conventional quantum confined Stark effect driven red shift and a suppressed binding energy driven anomalous blue shift of the emission lines, with the latter dominating in the low field regime. We also find that the encapsulating environment of the monolayer TMDC plays an important role in wave function spreading, and hence in determining the magnitude of the blue Stark shift. The results for neutral and charged excitonic species are in excellent agreement with calculations from Bethe-Salpeter Equation that uses seven-band per spin tight binding Hamiltonian. The findings have important implications in probing many-body interaction in the two dimension as well as in developing layered semiconductor based tunable optoelectronic devices.

description: Since the 1990s the retrospective of Russian and East-European Early-Modern societies has largely benefited from several methodological turns. Objects and profiles of the past reinterpreted in cultural terms are emerging against the anthropological background. This trend does not proceed to better consent in the historical community; rather it reconciles them against Soviet interpretations of the past. In the times of the Russian Empire and Soviet Union the East-European Early-Modern period was conceptualized in terms of “growth”, understood as a strengthening of the rulership and concentration of territories under the power of monarchs – grand dukes, later tsars, of Moscow and kings of the “Jagiellonian Empire”.

description: The Doppler effect is one of the dominant broadening mechanisms in thermal vapor spectroscopy. For two-photon transitions one would naively expect the Doppler effect to cause a residual broadening, proportional to the wave-vector difference. In coherent population trapping (CPT), which is a narrow-band phenomenon, such broadening was not observed experimentally. This has been commonly attributed to frequent velocity-changing collisions, known to narrow Doppler-broadened one-photon absorption lines (Dicke narrowing). Here we show theoretically that such a narrowing mechanism indeed exists for CPT resonances. The narrowing factor is the ratio between the atom's mean free path and the wavelength associated with the wave-vector difference of the two radiation fields. A possible experiment to verify the theory is suggested.

description: Fino agli anni Ottanta del XX secolo la ricerca sovietica si è in genere conformata al modello elaborato da K. Marx sulla base di fatti caratteristici della storia europea, ai quali si cercava di ricondurre anche la storia della Russia. L’idea di fondo era che tutti i Paesi attraversassero fasi di sviluppo simili, anche se non nello stesso momento. Il percorso marxista, perseguito sino in fondo dalla storiografia sovietica, si è rivelato istruttivo, o addirittura traumatico, per le generazioni successive di storici, perché ha mostrato come sia facile selezionare i fatti storici che si adattano a uno schema prestabilito, e come la ricerca costruita in questo modo si svuoti rapidamente di senso. Tutto ciò è particolarmente evidente negli studi dedicati alla storia del XVII secolo, perché su di esso, più che su altri secoli, “pesano” le concezioni marxiste della storia.

description: The interplay of strain engineering and photon-assisted tunneling of electrons in graphene is considered for giving rise to atypical transport phenomena. The combination of uniaxial strain and a time-periodic potential barrier helps to control the particle transmission for a wide range of tunable parameters. With the use of the tight-biding approach, the elasticity theory, and the Floquet scattering, we found an angular shift of the maximum transmission in the sidebands for uniaxial strains breaking the mirror symmetry with respect to the normal incidence, which is called anomalous Floquet tunneling. We show that electron tunneling depends strongly on the barrier width, incident angle, uniaxial strain, and the tuning of the time-periodic potential parameters. An adequate modulation of the barrier width and oscillation amplitude serves to select the transmission in the sidebands. These findings can be useful for controlling the electron current through the photon-assisted tunneling being used in multiple nanotechnological applications.

description: We compute the operator which creates the missing degenerate states in the algebraic Bethe ansatz of the 8 vertex model at roots of unity and relate it to the concept of an elliptic current operator. We find that in sharp contrast with the corresponding formalism in the six-vertex model at roots of unity the current operator is not nilpotent with the consequence that in the construction of degenerate eigenstates of the transfer matrix an arbitrary number of exact strings can be added to the set of regular Bethe roots. Thus the original set of free parameters {s,t} of an eigenvector of T is enlarged to become {s,t,λ_{c,1}, ..., λ_{c,n}\} with arbitrary string centers λ_{c,j} and arbitrary n.

Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to answer three research questions concerning the measurement of treatment adherence of Experiential Systemic Therapy (ExST) and Supported Feedback Therapy (SFT) in the Alcohol Recovery Project. First, is the Adherence Rating Scale Reliable and Valid? Second, to what extent do the therapists adhere to and emulate the respective treatments described in the ExST and SFT manuals? Third, are individual and couple's ExST treatment, as performed, mdistinguishable from one another and different than SFT treatment? Observer ratings of 120 video taped sessions were used to establish reliability and validity of tating scale, and to measure treatment adherence in terms of extensiveness, emulation and distinctiveness. A cluster analysis of the session profiles was conducted, establishing clear support for adherence and emulation. The clusters differentiated between ExST and SFT treatment modalities for 97% of the sessions, and did not differentiate between individual and couple's ExST. Treatment modality was also shown to be highly related to cluster indicating high levels of adherence.

description: Society is undergoing many transformations and faces economic crises, environmental, social, and public health issues. At the same time, the Internet, mobile communications, cloud technologies, and social networks are growing rapidly and fostering the digitalization processes of business and society. It is in this context that the shared economy has assumed itself as a new social and economic system based on the sharing of resources and has allowed the emergence of innovative businesses like Airbnb. However, COVID-19 has challenged this business model in the face of restrictions imposed in the tourism sector. Its consequences are not exclusively short-term and may also call into question the sustainability of Airbnb. In this sense, this study aims to explore the sustainability of the Airbnb business model considering two theories which advocate that hosts can cover the short-term financial effects, while another defends a paradigm shift in the demand for long-term accommodations to ensure greater stability for hosts.

description: This paper addresses the problem of bearing-only formation control in $d~(d\geq 2)$-dimensional space by exploring persistence of excitation (PE) of the desired bearing reference. By defining a desired formation that is bearing PE, distributed bearing-only control laws are proposed, which guarantee exponential stabilization of the desired formation only up to a translation vector. The key outcome of this approach relies in exploiting the bearing PE to significantly relax the conditions imposed on the graph topology to ensure exponential stabilization, when compared to the bearing rigidity conditions, and to remove the scale ambiguity introduced by bearing vectors. Simulation results are provided to illustrate the performance of the proposed control method.

description: La storia dei doni simbolici inviati da Dario a Alessandro Magno (Romanzo di Alessandro 1.36-38) è derivata da una raccolta ellenistica di lettere fittizie che raccontavano la spedizione del conquistatore Macedone. Un modello diretto di quella narrazione fu la leggenda sui regali enigmatici mandati dagli Sciti a Dario I, che è narrata da Erodoto (4.131-132) e altre fonti ed era ben nota nell’epoca ellenistica. Oltre a questo, la storia di Alessandro e Dario è anche influenzata da tradizioni orali di folclore e divertimento, ugualmente riconducibili all’età ellenistica. Il re Persiano e quello Macedone competono nell’offerta di spiegazioni contrastanti degli oggetti simbolici; le loro spiegazioni sono collocate in una sorta di scala ascendente dal più debole al più forte. Secondo l’interpretazione di Alessandro, gli oggetti rappresentano le nozioni di potere e di conquista, superando in tal modo l’allegoria più debole di puerilità e sottomissione proposta da Dario. Questo schema narrativo ricorda giochi di enigmi con analoga struttura a gradi, che vengono attestati da Difilo e Clearco di Soli per simposi di prima età ellenistica. In tali gare scherzose, due o più giocatori tentavano di superarsi l’un l’altro, trovando ogni volta una soluzione più forte per lo stesso indovinello.

description: We continue the study of the assignment problem for a random cost matrix. We analyse the number of $k$-cycles for the solution and their dependence on the symmetry of the random matrix. We observe that for a symmetric matrix one and two-cycles are dominant in the optimal solution. In the antisymmetric case the situation is the opposite and the one and two-cycles are suppressed. We solve the model for a pure random matrix (without correlations between its entries) and give analytic arguments to explain the numerical results in the symmetric and antisymmetric case. We show that the results can be explained to great accuracy by a simple ansatz that connects the expected number of $k$-cycles to that of one and two cycles.

description: A correlation between the metallicity, [M/H], and rest-frame MgII equivalent width, EW, is found from 49 DLAs and strong sub-DLAs drawn from the literature over the redshift range 0.20.7A, the correlation remains at >3 sigma significance. Since the MgII2796 transition is predominantly saturated in DLAs (which always have EW greater than 0.3A), EW is far more sensitive to the kinematic spread of the metal velocity components across the absorption profile than it is to [M/H]. Thus, the observed [M/H]--EW correlation points to a strong link between the absorber metallicity and the mechanism for producing and dispersing the velocity components. We also note that approximately half of the 13 known molecular hydrogen absorbers have very high EW and very broad velocity structures which show characteristics usually associated with outflows. Follow-up ultraviolet- and blue-sensitive high-resolution spectra of high-EW systems, initially identified in low-resolution spectra, may therefore yield a large number of new H_2 discoveries.

description: The melleolides are a family of structurally and functionally diverse sesquiterpenoids with potential applications as fungicides, antimicrobials, and cancer therapeutics. The initial and terminal steps of the biosynthesis pathway in Armillaria spp. have been characterized, but the intermediate steps are unclear. Biosynthetic gene clusters in A. mellea and A. gallica were shown to encode a terpene cyclase, a polyketide synthase, and four CYP450 monooxygenases. We have characterized CYPArm3, which is responsible for the hydroxylation of Δ‐6‐protoilludene, but the functions of the other CYP450s remain to be determined. Here we describe CYPArm2, which accepts Δ‐6‐protoilludene and 8α‐hydroxy‐6‐protoilludene as substrates. To investigate the products in more detail, we generated recombinant Saccharomyces cerevisiae strains overexpressing CYPArm2 in combination with the previously characterized protoilludene synthase and 8α‐hydroxylase. Using this total biosynthesis approach, sufficient quantities of product were obtained for NMR spectroscopy. This allowed the identification of 8α,13‐dihydroxy‐protoilludene, confirming that CYPArm2 is a protoilludene 13‐hydroxylase.

description: Since the first non-thermal reports of inverse Compton (IC) emission from the intracluster medium (ICM) of galaxy clusters at hard X-ray energies, we have yet to unambiguously confirm IC emission in observations with newer facilities. RXTE detected IC emission in one of the hottest known clusters, Abell 2163 (A2163), a massive merging cluster with a giant radio halo--the presumed source of relativistic electrons IC scattering CMB photons to X-ray energies. The cluster's redshift (z~0.2) allows its thermal and non-thermal radio emission to fit NuSTARS's FOV, permitting a deep observation capable of confirming or ruling out the RXTE report. The IC flux provides constraints on the average magnetic field strength in a cluster. To determine the global diffuse IC emission in A2163, we fit its global NuSTAR spectrum with four models: single (1T) and two-temperature (2T), 1T+power law component (T+IC), and multi-temperature+power law (9T+IC). Each represent different characterizations of the thermal ICM emission, with power law components added to represent IC emission. We find the 3-30 keV spectrum can be described by purely thermal emission, with a global average temperature of kT = (11.8 $\pm$ 0.2) keV. The IC flux is constrained to $$ $0.22$$μ$$G$ and $>$ $0.35$$μ$$G$, respectively, providing the strongest constraints on these values in A2163 to date.

description: We observe antibunching in the photons emitted from a strongly-coupled single quantum dot and pillar microcavity in resonance. When the quantum dot was spectrally detuned from the cavity mode, the cavity emission remained antibunched, and also anticorrelated from the quantum dot emission. Resonant pumping of the selected quantum dot via an excited state enabled these observations by eliminating the background emitters that are usually coupled to the cavity. This device demonstrates an on-demand single photon source operating in the strong coupling regime, with a Purcell factor of 61 and quantum effciency of 97%

description: This is the first in a series of papers devoted to generalisations of statistical loop models. We define a lattice model of $U_q(\mathfrak{sl}_n)$ webs on the honeycomb lattice, for $n \ge 2$. It is a statistical model of closed, cubic graphs with certain non-local Boltzmann weights that can be computed from spider relations. For $n=2$, the model has no branchings and reduces to the well-known O($N$) loop model introduced by Nienhuis. In the general case, we show that the web model possesses a particular point, at $q=e^{i π/(n+1)}$, where the partition function is proportional to that of a $\mathbb{Z}_n$-symmetric chiral spin model on the dual lattice. Moreover, under this equivalence, the graphs given by the configurations of the web model are in bijection with the domain walls of the spin model. For $n=2$, this equivalence reduces to the well-known relation between the Ising and O($1$) models. We define as well an open $U_q(\mathfrak{sl}_n)$ web model on a simply connected domain with a boundary, and discuss in particular the role of defects on the boundary.

description: We consider a model Hamiltonian describing the interaction of a single-mode radiation field with the atoms of a nonlinear medium, and study the dynamics of entanglement for specific non-entangled initial states of interest: namely, those in which the field mode is initially in a Fock state, a coherent state, or a photon-added coherent state. The counterparts of near-revivals and fractional revivals are shown to be clearly identifiable in the entropy of entanglement. The ``overlap fidelity'' of the system is another such indicator, and its behaviour corroborates that of the entropy of entanglement in the vicinity of near-revivals. The expectation values and higher moments of suitable quadrature variables are also examined, with reference to possible squeezing and higher-order squeezing.

Il «pulvis et umbra» oraziano in alcuni poeti latini tardoantichi
Creators: name: Castelnuovo, Elena
Publisher: name: ACME
Year: 2015

description: L’affermazione di Orazio pulvis et umbra sumus (Carm. 4.7.16) ha lasciato un’impronta nei poeti successivi? Scopo dell’articolo è analizzare l’influenza di un tale verso su tre autori tardoantichi: Ausonio, Paolino di Nola e Venanzio Fortunato. Essi si rifanno al modello in modi differenti: se Ausonio si limita a riprodurre il verso di Orazio, Paolino, invece, riprende i termini pulvis et umbra aggiungendovi sine Christo, per mettere in luce la diversità fra la visione pagana e la sua concezione di vita rinnovata dalla conversione. Inoltre, echi dalle Scritture nei due passi di Paolino e di Venanzio portano a una ricchezza di significato dovuta all’incontro fra la tradizione classica e quella biblica. Un’appendice tenta di rispondere alla domanda su quale testo del Salterio conoscesse Paolino.

Tommaseo e la narrativa storica: dalla riflessione sull’«Antologia» ai racconti
Creators: name: Giardini, Arianna
Publisher: name: ACME
Year: 2015

description: Il contributo esamina la riflessione di Tommaseo sulla narrativa storica in relazione alla successiva redazione dei racconti, attraverso lo studio degli articoli apparsi sull’«Antologia». Si analizza l’attività critica dello scrittore e, in particolare, l’insoddisfazione per gli esiti dei romanzi recensiti quali elementi indispensabili per la futura elaborazione delle sue singolari soluzioni narrative. L’individuazione delle specificità della prassi narrativa tommaseana ne mette tuttavia in luce anche gli scarti rispetto alla sua poetica storica. Funzionale in tal senso è la recensione ai Promessi sposi, dove Tommaseo mostra di non comprendere pienamente le ragioni dell’opera e il ruolo dell’invenzione, benché condivida l’intento educativo e divulgativo di Manzoni. Tuttavia, la ricerca dell’essenzialità e della poesia come condizioni per un buon romanzo approderà a strutture antinarrative e a una prosa d’arte destinate a un pubblico meno ampio di quello manzoniano: si esclude così l’incolto destinatario di quella pedagogia del romanzo espressa nella rivista fiorentina.

description: Using a combination of ground-based and HST imaging, we have constructed a catalog of 179 supernova remnants (SNRs) and SNR candidates in the nearby spiral galaxy M51. Follow-up spectroscopy of 66 of the candidates confirms 61 of these as SNRs, and suggests that the vast majority of the unobserved objects are SNRs as well. A total of 55 of the candidates are coincident with (mostly soft) X-ray sources identified in deep Chandra observations of M51; searching the positions of other soft X-ray sources resulted in several additional possible optical candidates. There are 16 objects in the catalog coincident with known radio sources. None of the sources with spectra shows the high velocities (>500 km/s) characteristic of young, ejecta-dominated SNRs like Cas A; instead, most if not all appear to be middle-aged SNRs. The general properties of the SNRs, size distribution and spectral characteristics, resemble those in other nearby spiral galaxies, notably M33, M83, and NGC6946, where similar samples exist. However, the spectroscopically observed [N II]:Hα ratios appear to be significantly higher than in any of these other galaxies. Although we have explored various ideas to explain the high ratios in M51, none of the explanations appears to be satisfactory.

description: The COVID-19 pandemic highlighted the importance of internet access across various aspects of life, from remote work and online education to healthcare services and social connections. As we transition to a post-pandemic era, a pressing need arises to update our understanding of the multifaceted nature of internet access. This study is one of the first attempts to do so. Using survey data from New Zealand adult internet users (n = 960), it compares internet connection types, frequency of internet use at home, social media use, and concerns about online risk between people with and without disabilities. Results show people with disabilities have restricted fibre access and higher wireless broadband (a much slower connection type). People with disabilities use social media platforms less and are more concerned about certain online risks. The findings highlight persistent disparities in internet access for people with disabilities in the post-pandemic era. Implications of the study are discussed.

description: By muon spin rotation we investigated the magnetic properties of a series of highly Na doped NaxCoO2 single crystals with 0.78(1)0.04 until they yield a bulk magnetic state near x=0.78. Evidence for a strong (likely geometrical) frustration of the magnetic order is obtained from the anomalous doping dependence of the spin fluctuation rate (above the ordering temperature) which is strongly enhanced at x=0.78 as compared to x=0.97.

description: Detection of gravitational waves from accreting neutron stars (NSs) in our galaxy, due to ellipticity or internal oscillation, would be a breakthrough in our understanding of compact objects and explain the absence of NSs rotating near the break-up limit. Direct detection, however, poses a formidable challenge. Using the current data available on the properties of the accreting NSs in Low Mass X-Ray Binaries (LMXBs), we quantify the detectability for the known accreting NSs, considering various emission scenarios and taking into account the negative impact of parameter uncertainty on the data analysis process. Only a few of the persistently bright NSs accreting at rates near the Eddington limit are detectable by Advanced LIGO if they are emitting gravitational waves at a rate matching the torque from accretion. A larger fraction of the known population is detectable if the spin and orbital parameters are known in advance, especially with the narrow-band Advanced LIGO. We identify the most promising targets, and list specific actions that would lead to significant improvements in detection probability. These include astronomical observations (especially for unknown orbital periods), improvements in data analysis algorithms and capabilities, and further detector development.

description: Context: Lupus is recognised as one of the closest star-forming regions, but the lack of trigonometric parallaxes in the pre-Gaia era hampered many studies on the kinematic properties of this region and led to incomplete censuses of its stellar population. Aims: We use the second data release of the Gaia space mission combined with published ancillary radial velocity data to revise the census of stars and investigate the 6D structure of the Lupus complex. Methods: We performed a new membership analysis of the Lupus association based on astrometric and photometric data over a field of 160 deg2 around the main molecular clouds of the complex and compared the properties of the various subgroups in this region. Results: We identified 137 high-probability members of the Lupus association of young stars, including 47 stars that had never been reported as members before. Many of the historically known stars associated with the Lupus region identified in previous studies are more likely to be field stars or members of the adjacent Scorpius-Centaurus association. Our new sample of members covers the magnitude and mass range from G=8 to G=18 mag and from 0.03 to 2.4Msun, respectively. We compared the kinematic properties of the stars projected towards the molecular clouds Lupus 1 to 6 and showed that these subgroups are located at roughly the same distance (about 160~pc) and move with the same spatial velocity. Our age estimates inferred from stellar models show that the Lupus subgroups are coeval (with median ages ranging from about 1 to 3 Myr). The Lupus association appears to be younger than the population of young stars in the Corona-Australis star-forming region recently investigated by our team using a similar methodology. The initial mass function of the Lupus association inferred from the distribution of spectral types shows little variation compared to other star-forming regions.
