description: We investigate the correlation between the neutrino mass limit and dark energy with time evolving equation of state. Parameterizing dark energy as w=w_0+w_1*z/(1+z), we make a global fit using Markov Chain Monte Carlo technique to determine w_0, w_1, neutrino mass as well as other cosmological parameters simultaneously. We pay particular attention to the correlation between neutrino mass Σm_ν and w_1 using current cosmological observations as well as the future simulated datasets such as PLANCK, SNAP and LAMOST.

description: Galactic electron density distribution models are crucial tools for estimating the impact of the ionised interstellar medium on the impulsive signals from radio pulsars and fast radio bursts. The two prevailing Galactic electron density models are YMW16 (Yao et al., 2017) and NE2001 (Cordes & Lazio, 2002). Here, we introduce a software package PyGEDM which provides a unified application programming interface (API) for these models and the YT20 (Yamasaki & Totani, 2020) model of the Galactic halo. We use PyGEDM to compute all-sky maps of Galactic dispersion measure (DM) for YMW16 and NE2001, and compare the large-scale differences between the two. In general, YMW16 predicts higher DM values toward the Galactic anticentre. YMW16 predicts higher DMs at low Galactic latitudes, but NE2001 predicts higher DMs in most other directions. We identify lines of sight for which the models are most discrepant, using pulsars with independent distance measurements. YMW16 performs better on average than NE2001, but both models show significant outliers. We suggest that future campaigns to determine pulsar distances should focus on targets where the models show large discrepancies, so future models can use those measurements to better estimate distances along those line of sight. We also suggest that the Galactic halo should be considered as a component in future GEDMs, to avoid overestimating the Galactic DM contribution for extragalactic sources such as FRBs.

Dynamical evidence for a morphology-dependent relation between the stellar and halo masses of galaxies

description: We derive the stellar-to-halo mass relation (SHMR), namely $f_\star\propto M_\star/M_{\rm h}$ versus $M_\star$ and $M_{\rm h}$, for early-type galaxies from their near-IR luminosities (for $M_\star$) and the position-velocity distributions of their globular cluster systems (for $M_{\rm h}$). Our individual estimates of $M_{\rm h}$ are based on fitting a dynamical model with a distribution function expressed in terms of action-angle variables and imposing a prior on $M_{\rm h}$ from the concentration-mass relation in the standard $Λ$CDM cosmology. We find that the SHMR for early-type galaxies declines with mass beyond a peak at $M_\star\sim 5\times 10^{10}M_\odot$ and $M_{\rm h}\sim 10^{12}M_\odot$ (near the mass of the Milky Way). This result is consistent with the standard SHMR derived by abundance matching for the general population of galaxies, and with previous, less robust derivations of the SHMR for early types. However, it contrasts sharply with the monotonically rising SHMR for late types derived from extended HI rotation curves and the same $Λ$CDM prior on $M_{\rm h}$ as we adopt for early types. The SHMR for massive galaxies varies more or less continuously, from rising to falling, with decreasing disc fraction and decreasing Hubble type. We also show that the different SHMRs for late and early types are consistent with the similar scaling relations between their stellar velocities and masses (Tully-Fisher and Faber-Jackson relations). Differences in the relations between the stellar and halo virial velocities account for the similarity of the scaling relations. We argue that all these empirical findings are natural consequences of a picture in which galactic discs are built mainly by smooth and gradual inflow, regulated by feedback from young stars, while galactic spheroids are built by a cooperation between merging, black-hole fuelling, and feedback from AGNs.

description: The fusion reactions 12C(12C,a)20Ne and 12C(12C,p)23Na have been studied from E = 2.10 to 4.75 MeV by gamma-ray spectroscopy using a C target with ultra-low hydrogen contamination. The deduced astrophysical S(E)* factor exhibits new resonances at E <= 3.0 MeV, in particular a strong resonance at E = 2.14 MeV, which lies at the high-energy tail of the Gamow peak. The resonance increases the present non-resonant reaction rate of the alpha channel by a factor of 5 near T = 8x10^8 K. Due to the resonance structure, extrapolation to the Gamow energy E_G = 1.5 MeV is quite uncertain. An experimental approach based on an underground accelerator placed in a salt mine in combination with a high efficiency detection setup could provide data over the full E_G energy range.

Essays on strategic trade policy : market uncertainty, incomplete information, and credit rationing
Creators: name: Qiu, Dongxiao
Publisher: name: University of British Columbia
Year: 2008

description: This dissertation is a collection of three essays on strategic trade policy. The main purpose of this research is to make contributions to the strategic trade literature by dealing with some of its interesting and important issues. The first essay extends the well-known Brander-Spencer (1985) model, by considering market uncertainty, endogenizing firms' choice of strategic variables, and introducing a quadratic export tax/subsidy scheme; and investigates the interrelationship between trade policies and market competition. It is shown that firms are not indifferent between setting prices and setting quantities in an uncertain environment. The quadratic export tax/subsidy scheme is proved superior to the linear export tax/subsidy scheme because the former has the unique ability to influence the domestic firm's choice of strategic variables and therefore to affect the market conduct in favour of the domestic country. The second essay explores an incomplete information version of the Brander-Spencer (1985) model, in which the domestic firm's production cost is private in-formation. This model has the distinguishing feature that it contains a mixture of screening and signalling problems. Because of this, policy makers are confronted by twin conflicting policy objectives: choosing between an information revealing policy menu and an information concealing uniform policy. We prove that the policy menu is preferred to the uniform policy in quantity competition while the opposite is true in price competition. In essay three, we examine the implications of credit rationing for international trade. Development and production of new products often involves uncertainty (e.g. R&D uncertainty and demand uncertainty), which could lead to credit rationing. We find that the presence of credit rationing may give partial explanation for the indeterminacy of the pattern of trade between two similar countries. When credit is rationed, two-way trade is less likely to occur.

description: A hypothesis of the existence of a long-lived isotope 271Hs in natural molybdenites and osmirides is considered from a geochemical point of view. It is shown that the presence of Hs in these minerals can be explained only by making an additional ad hoc assumption on the existence of an isobaric pair of 271Bh-271Hs. This assumption could be tested by mass-spectrometric measurements of U, Pb, Kr, Xe, and Zr isotopic shifts.

description: We probe the formation scenarios and the active galactic nuclei (AGN) occupation fraction of ultra-diffuse galaxies (UDGs) in the nearby Coma cluster by utilizing XMM-Newton observations of 779 out of 854 UDG candidates identified by Subaru survey. Their origin is probed by measuring the dark matter halo mass of the stacked sample of UDGs and the population of low-mass X-ray binaries residing in globular clusters. Our measurements suggest that the average UDG population does not have a substantial amount of hot gas or a large number of globular clusters. This supports the formation scenario, in which UDGs are puffed-up dwarf galaxies, agreeing with that obtained for 404 Coma cluster UDGs using Chandra. We also determine AGN occupation fraction of UDGs by cross-correlating the position of UDGs with the detected point sources in Coma. We detect three X-ray sources with detection significance $σ\geq 5$ that could be off-centre AGN within 5 arcsec from the centre of the UDG 317, UDG 432, and UDG 535. We identify an optical counterpart for the X-ray source associated with the UDG 317, suggesting that this source is more likely an off-centre AGN. Based on the current data, however, we cannot conclusively constrain whether the detected AGN is residing in the Coma cluster or not.

description: Rapidity/seudorapidity densities for charged particles and their centrality, rapidity and energy dependence in Au+Au collisions at RHIC are studied in a quark combination model. Using a Gaussian-type rapidity distribution for constituent quarks as a result of Landau hydrodynamic evolution, the data at $\sqrt{s_{NN}}=130, 200$ GeV at various centralities in full pseudorapidity range are well described, and the charged particle multiplicity are reproduced as functions of the number of participants. The energy dependence of the shape of the $dN_{ch}/dη$ distribution is also described at various collision energies $\sqrt{s_{NN}}=200, 130, 62.4$ GeV in central collisions with same value of parameters except 19.6 GeV. The calculated rapidity distributions and yields for the charged pions and kaons in central Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV are compared with experimental data of the BRAHMS Collaboration.

description: We revisit the flavor symmetries arising from compactifications on tori with magnetic background fluxes. Using Euler's Theorem, we derive closed form analytic expressions for the Yukawa couplings that are valid for arbitrary flux parameters. We discuss the modular transformations for even and odd units of magnetic flux, M, and show that they give rise to finite metaplectic groups the order of which is determined by the least common multiple of the number of zero-mode flavors involved. Unlike in models in which modular flavor symmetries are postulated, in this approach they derive from an underlying torus. This allows us to retain control over parameters, such as those governing the kinetic terms, that are free in the bottom-up approach, thus leading to an increased predictivity. In addition, the geometric picture allows us to understand the relative suppression of Yukawa couplings from their localization properties in the compact space. We also comment on the role supersymmetry plays in these constructions, and outline a path towards non-supersymmetric models with modular flavor symmetries.

description: We present multi-band Hubble Space Telescope imaging that spans rest-frame near-ultraviolet through near-infrared wavelengths (0.3-1.1 $μ$m) for 12 compact starburst galaxies at z=0.4-0.8. These massive galaxies (M_stellar ~ 10^11 M_Sun) are driving very fast outflows ($v_{max}$=1000-3000 km/s), and their light profiles are dominated by an extremely compact starburst component (half-light radius ~ 100 pc). Our goal is to constrain the physical mechanisms responsible for launching these fast outflows by measuring the physical conditions within the central kiloparsec. Based on our stellar population analysis, the central component typically contributes $\approx$25% of the total stellar mass and the central escape velocities $v_{esc,central}\approx900$ km/s are a factor of two smaller than the observed outflow velocities. This requires physical mechanisms that can accelerate gas to speeds significantly beyond the central escape velocities, and it makes clear that these fast outflows are capable of traveling into the circumgalactic medium, and potentially beyond. We find central stellar densities comparable to theoretical estimates of the Eddington limit, and we estimate $Σ_1$ surface densities within the central kpc comparable to those of compact massive galaxies at $0.5

Επίσης πραγματοποιήθηκαν πειράματα έμμεσου ανοσοφθορισμού για τη μελέτη της υποκυτταρικής εντόπισης της κινάσης που έδειξαν ότι η κινάση εντοπίζεται σε όλο το κύτταρο.
description: The aim of this study was to investigate the role of SRPK1 down-regulation in dental pulp stem cells (DPSCs). The starting point for this study was the observation that the deprivation of important molecules in these cells induce their differentiation. Since SRPK1 has been implicated in a variety of cellular processes we decided to study whether the down-regulation of SRPK1 expression levels induce differentiation of DPSCs. Verification of differentiation of these cells was achieved by determining the levels of expression of four osteogenic factors ALP, MSX1, BMP2 and BGLAP. Real-time PCR results showed that down-regulation of SRPK1 expression has a significant effect on the MSX1 expression levels. Also indirect immunofluorescence experiments were performed to study the subcellular localization of the kinase. The kinase was detected throughout the cell.

Οι δύο ποιήτριες, μολονότι πραγματεύονται θέματα οικεία στο κίνημα του υπερρεαλισμού, αποπειρώνται για πρώτη φορά να τα θέσουν υπό το πρίσμα μιας νέας, αμιγώς γυναικείας οπτικής. Η προσέγγισή τους συνεπώς προσδίδει έναν αυτοαναφορικό χαρακτήρα στο έργο τους, ενδεικτικό των ασυνείδητων ψυχικών διεργασιών τους, μέσω του οποίου προσπαθούν να καταδείξουν –μεταξύ άλλων– την πολυπλοκότητα της γυναικείας σεξουαλικότητας ταυτόχρονα αναδεικνύουν έναν νέο τύπο γυναίκας, η οποία εναλλάσσει με ευκολία διαφορετικούς ρόλους, κατ’ αντιστοιχία προς το ευρύ φάσμα των καινοφανών δραστηριοτήτων της. Οι δύο ποιήτριες, σπάζοντας το φράγμα του ανδροκρατούμενου υπερρεαλισμού, συμπορεύτηκαν με τους υπερρεαλιστές αντί να αναπαράγουν άκριτα τους τρόπους έκφρασής τους. Με αυτόν τον τρόπο, επαναδιαπραγματεύθηκαν μια σειρά πατριαρχικές στερεοτυπικές αντιλήψεις τις οποίες διαιώνιζαν οι παραδοσιακές κοινωνικές δομές και, τελικά, δημιούργησαν μια νέα ποιητική γλώσσα εστιασμένη σε πτυχές της γυναικείας φύσης που η ανδρική ποίηση επέλεγε να αφήνει αφώτιστες ή απλώς αγνοούσε. Εν κατακλείδι, εάν η υπερρεαλιστική ποιητική λειτούργησε γονιμοποιητικά και ανανεωτικά στη διαμόρφωση των δύο αυτών γυναικείων ποιητικών φωνών, οι τελευταίες εμπλούτισαν εξίσου με τη σειρά τους την ίδια την εκφραστική παλέτα του υπερρεαλισμού.
description: This MA thesis attempts to shed light on the poetry of two surrealist women poets, that of Greek Matsie Chandjilazaros (1914-1987) and francophone Egyptian Joyce Mansour (1928-1986). Although they manipulate familiar to the surrealist movement subjects, they try for the first time to approach their material from a female point of view. This adds to their poetry a self-referential value indicative of their own subconscious mental processes through which they try to reveal the complexity of female sexuality and at the same time suggest the emergence of a new woman type with multiple roles matching her multiple activities. The two poets end up actively engaging with the Surrealists after surpassing the male-oriented barriers existing within the surrealist movement rather than passively using Surrealism as a convenience platform for their own artistic work. In this way, they manage to expose subjects and stereotypes brought forth by patriarchal conventions and eventually bring to the center of attention some of the feminine subjects that male poetry always neglected or just ignored. Consequently, with the surrealist poetics having a multiplying and regenerative impact on the formation of these two female voices, one could also claim that the two poets in question equally enriched the surrealist writing practices with their own contributions.
Participation in and employee attitude toward organizational change : a case study on strategic change at George Pearson Centre
Creators: name: Clay, Nancy Margaret
Publisher: name: University of British Columbia
Year: 2008

description: The British Columbia Rehabilitation Society (B.C. Rehab)recently approved a strategic plan which, when implemented, will change the organization's delivery of services to British Columbians with disabilities. In addition to a review of the literature to determine the factors influencing employees’ participation in the strategic change process and their attitudes to it, this case study employs two primary methods of inquiry. Firstly, B.C. Rehab's strategy development process is identified and examined through perusal of B.C. Rehab documents. Secondly, a self-administered mail questionnaire surveys employees' attitudes toward the strategic change effort and their participation in the planning. Results reveal that the organization followed a corporate planning model of strategic change; strategy formulation was accomplished through strategic planning. This method of strategy formation is consistent with B.C. Rehab's traditional structure and its apparent adherence to hierarchical authority. Results reveal differential opportunity to participate in strategic planning according to organizational role. Those in professional/management roles report greater opportunity to participate than those in non-professional designations. More impoverished understanding of the strategic plan and weaker overall agreement with the organization’s five strategic goals are reported by the non-professional group. Employees' concerns about the strategic plan relate to feelings of uncertainty about their future with the organization. In addition to their prediction of its being the most difficult to implement, staff report a high degree of ambivalence to the goal to move to a "consumer-driven" framework. Respondents assess employees' overall attitude toward the strategic plan as ambivalent. The results lend support to organizational models which encourage employee participation. However, it is concluded that several elements, including the organization's cultures, its structure and politics, interact to systematically pre-determine employees' participation in decision-making processes.

description: An integral coefficient matrix determines an integral arrangement of hyperplanes in R^m. After modulo q reduction, the same matrix determines an arrangement A_q of "hyperplanes" in Z^m. In the special case of central arrangements, Kamiya, Takemura and Terao [J. Algebraic Combin., to appear] showed that the cardinality of the complement of A_q in Z_q^m is a quasi-polynomial in q. Moreover, they proved in the central case that the intersection lattice of A_q is periodic from some q on. The present paper generalizes these results to the case of non-central arrangements. The paper also studies the arrangement B_m^{[0,a]} of Athanasiadis [J. Algebraic Combin. Vol.10 (1999), 207-225] to illustrate our results.

Επιπλέον η εργασία αυτή εστιάζει και στην εξέταση των μη εναρμονισμένων ειδικών φόρων κατανάλωσης, όπως αυτοί είτε εφαρμόζονταν στο παρελθόν είτε συνεχίζουν να εφαρμόζονται μέχρι σήμερα στην Ελλάδα. Καίρια ζητήματα που αναδεικνύονται είναι η σημασία της εναρμόνισης των ειδικών φόρων κατανάλωσης προς το Κοινοτικό Δίκαιο τόσο για την ίδια την Ε.Ε. και τα κράτη-μέλη όσο και για την τήρηση της αρχής του ελεύθερου ανταγωνισμού και της βελτίωσης των δημοσιονομικών εσόδων των κρατών-μελών. Η εξέταση των ζητημάτων αυτών γίνεται κυρίως μέσα από την επισκόπηση της νομολογίας του Ευρωπαϊκού Δικαστηρίου, το οποίο με τις αποφάσεις του προσπαθεί να επιλύσει τις διαφορές και τις διαφορετικές προσεγγίσεις των κρατών-μελών γύρω από το ζήτημα της επιβολής των ειδικών φόρων κατανάλωσης.
description: The aim of the present thesis is to examine and clarify the regulatory context referring to excise duties, as it is in force today through the harmonization with Community Law and also through Greek legislation. Furthermore, this thesis focuses on the examination of non-harmonized excise duties which were forced the past decades or some of them are even forced until today in Greece. Among the main issues examined, one can particularly take note of the meaning that the harmonization of excise duties with Community Law has, not only for European Union and the members but also for the compliance with the basic rule of “free competition” and the improvement of members’ fiscal revenues. The presentation of the above-mentioned issues takes place mainly through the examination of the decisions of European Court, which through the decisions makes efforts to resolve the conflicts and the different approaches that members have on the issue of excise duties enforcement.

description: Στην παρούσα διπλωματική εργασία παρουσιάζουμε δύο θεωρήματα του A. Weinstein που αφορούν υποπολλαπλότητες συμπλεκτικών πολλαπλοτήτων. Το πρώτο θεώρημα μας διασφαλίζει ότι όταν δύο συμπλεκτικές μορφές επί μίας πολλαπλότητας συμπίπτουν σε μία υποπολλαπλότητα της, τότε είναι συμπλεκτομορφικές. Ενώ το δεύτερο θεώρημα και το πόρισμα του μας πληροφορούν πότε μία Λαγκρανζιανή υποπολλαπλότητα μίας συμπλεκτικής πολλαπλότητας μπορεί να θεωρηθεί ως η Λαγκρανζιανή υποπολλαπλότητα-βάση της συνεφαπτόμενης δέσμης της.
description: In this thesis we present two theorems of A. Weinstein that pertain to submanifolds of symplectic manifolds. The first theorem assures us that, when two symplectic forms on a manifold coincide in a submanifold of its manifold, then these two forms are symplectomorphic. While the second theorem and its corollary inform us when a Lagrangian submanifold of a symplectic manifold can be regarded as the Lagrangian submanifold-base of its cotangent bundle.

description: Σε αυτή την εργασία περιγράφονται αλγόριθμοι συστάσεων, ο εμπλουτισμός των δεδομένων μέσω της εκμετάλλευσης ανοικτών διασυνδεδεμένων δεδομένων, η δημιουργία ενός τέτοιου αλγορίθμου ώστε να εξεταστεί το όφελος που προκύπτει και τέλος ο σχεδιασμός μίας εφαρμογής για την εύρεση προτεινόμενων ταινιών. Οι αλγόριθμοι συστάσεων μπορούν να έχουν πολλές διαφορετικές εκφάνσεις, με πολλές από τις οποίες ερχόμαστε συχνά σε επαφή χωρίς συνήθως να το αντιλαμβανόμαστε, όπως τους ιστότοπους: Amazon , Netflix, EBay, YouTube, κ.α. O Λόγος που υπάρχουν τόσες διαφορετικές μηχανές συστάσεων είναι η αύξηση των πωλήσεων και η ευχρηστία το εκάστοτε ηλεκτρονικού καταστήματος ή μίας υπηρεσίας αυξάνοντας έτσι το κέρδος και την επισκεψιμότητα. Όσον αφορά τα δεδομένα που θα χρησιμοποιηθούν στο χτίσιμο του αλγορίθμου, επιλέξαμε να ασχοληθούμε με κινηματογραφικά δεδομένα από τον ιστότοπο Movielens, ο οποίος παρέχει δεδομένα από πραγματικές βαθμολογίες χρηστών αλλά και τους τύπους των ταινιών που βαθμολογήθηκαν. Τα δεδομένα εμπλουτίστηκαν περαιτέρω χρησιμοποιώντας τους πόρους της Wikipedia. Ο ευκολότερος τρόπος για να αντληθούν μαζικά τα δεδομένα είναι μέσω του end-point της DBpedia. Στη συνέχεια τα δεδομένα αποσφαλματώθηκαν και μορφοποιήθηκαν ώστε να δημιουργηθεί ένα εύχρηστο dataset για την υλοποίηση του αλγορίθμου. Ακολούθως ελέγξαμε τη διαφορά που προκύπτει στα αποτελέσματα μετά την χρήση των διασυνδεδεμένων δεδομένων . Τέλος σχεδιάσαμε μια εφαρμογή η οποία μας βοηθά να βρούμε όμοιες ταινίες. Η εργασία αυτή δίνει μία βάση για το πώς μπορεί να εκμεταλλευτεί κανείς τα διασυνδεμένα δεδομένα σε τέτοια συστήματα.
description: In this work we describe recommender system algorithms, the creation of one such algorithm, and the augmentation of data using Open Linked Data. Recommendation system algorithms can be found in many forms, which we usually come across without even noticing, as is with the case of the sites: Amazon , Netflix, EBay, YouTube, and other. The reason there are so many different recommender systems is the increase of sales and the friendliness of the site, thus increasing profit and times of visit. For the data we are going to use for the creation of our recommender, we choose to use cinematography data from the site Movielens, which provides files with real ratings of movies by real users and also the types of each movie. The data was enriched using Wikipedia resources. The easiest way to quickly obtain big data is through the DBpedia end-point by SPARQL querying taking advantage of the ontologies. Next the data was cleaned and formatted, to make it suitable for creating our algorithm, using R and mainly the library “SPARQL” and Open refine. For the creation of the algorithm we once again used R and the very helpful library for this case “recommenderlab”. Finally we built a simple recommender, which will help find movies similar to one we like.
Planning for industrialization in central Java, Indonesia : the process, the impacts and the alternatives
Creators: name: Hadi, Sudharto P.

description: This study identifies the Indonesian policies that established large scale, export oriented and externally controlled (LEE)industrialization from the perspective of local people in the industrializing area, the planning that implemented these policies in Central Java and the ways in which the local people's lives are being affected. It identifies the links between the policy and the planning, and between the planning and the impacts. This study is based on data gathered from provincial, municipal and local planners, affected people, factory owners, and workers. LEE industrial development has often been successful in terms of its contribution to Regional Gross Domestic Product (GDP) and to the creation of low wage employment opportunities. However, this success has been accompanied by significant economic, social and environmental impacts on local people. The economic impacts include loss of livelihood and jobs, and decrease of family income. The social impacts comprise the weakening of community cohesion and the disruption of the people's daily lives. The environmental impacts include floods, lack of clean water, water pollution, and air pollution. The impacts of LEE industrialization have been documented by various studies including this one. What has not been adequately analyzed and documented is the process that produces the impacts. This study helps to fill the gap. It concludes that the impacts stem from the following factors. The national development emphasizes large scale and export oriented industrialization. The top-down development planning ensures that this policy is supported at the provincial level regardless of local conditions, needs and priorities. The arbitrary nature of provincial decision-making provides for no popular input. Impact assessment studies fail to provide the information necessary for planners, decision-makers and ideally the local leaders about the likely impacts of industrialization. The way the responsible government agencies solve environmental problems tends to protect factory interests. The impacts are exacerbated by a lack of adequate monitoring and enforcement of environmental regulations. The thesis concludes that substantive policy reform and process restructuring are required to achieve sound planning for industrial development. If quality of life is to be protected and enhanced, industrial policies should be reoriented to strengthening existing local economic activities; and planning restructured to enable local planners and affected people to be fully involved at all stages including impact management.

description: Assistive Technologies (AT) in the form of prompting systems can help people with Acquired Brain Injury (ABI) cope with cognitive impairments and executive dysfunction. We examined the common injury-induced difficulties in everyday life, the standard rehabilitation practices in the field, and the use of external aids by people with ABI. Based on the findings, we outline some initial guidelines for the design of prompting systems to improve daily functioning of people with ABI.

Delayed Radio Flares from a Tidal Disruption Event

description: Radio observations of tidal disruption events (TDEs) - when a star is tidally disrupted by a supermassive black hole (SMBH) - provide a unique laboratory for studying outflows in the vicinity of SMBHs and their connection to accretion onto the SMBH. Radio emission has been detected in only a handful of TDEs so far. Here, we report the detection of delayed radio flares from an optically-discovered TDE. Our prompt radio observations of the TDE ASASSN-15oi showed no radio emission until the detection of a flare six months later, followed by a second and brighter flare, years later. We find that the standard scenario, in which an outflow is launched briefly after the stellar disruption, is unable to explain the combined temporal and spectral properties of the delayed flare. We suggest that the flare is due to the delayed ejection of an outflow, perhaps following a transition in accretion states. Our discovery motivates observations of TDEs at various timescales and highlights a need for new models.

description: We are interested in the widespread problem of clustering documents and finding topics in large collections of written documents in the presence of metadata and hyperlinks. To tackle the challenge of accounting for these different types of datasets, we propose a novel framework based on Multilayer Networks and Stochastic Block Models. The main innovation of our approach over other techniques is that it applies the same non-parametric probabilistic framework to the different sources of datasets simultaneously. The key difference to other multilayer complex networks is the strong unbalance between the layers, with the average degree of different node types scaling differently with system size. We show that the latter observation is due to generic properties of text, such as Heaps' law, and strongly affects the inference of communities. We present and discuss the performance of our method in different datasets (hundreds of Wikipedia documents, thousands of scientific papers, and thousands of E-mails) showing that taking into account multiple types of information provides a more nuanced view on topic- and document-clusters and increases the ability to predict missing links.

Reassessing the computational advantage of quantum-controlled ordering of gates

description: Research on indefinite causal structures is a rapidly evolving field that has a potential not only to make a radical revision of the classical understanding of space-time but also to achieve enhanced functionalities of quantum information processing. For example, it is known that indefinite causal structures provide exponential advantage in communication complexity when compared to causal protocols. In quantum computation, such structures can decide whether two unitary gates commute or anticommute with a single call to each gate, which is impossible with conventional (causal) quantum algorithms. A generalization of this effect to $n$ unitary gates, originally introduced in M. Araújo et al., Phys. Rev. Lett. 113, 250402 (2014) and often called Fourier promise problem (FPP), can be solved with the quantum-$n$-switch and a single call to each gate, while the best known causal algorithm so far calls $O(n^2)$ gates. In this work, we show that this advantage is smaller than expected. In fact, we present a causal algorithm that solves the only known specific FPP with $O(n \log(n))$ queries and a causal algorithm that solves every FPP with $O(n\sqrt{n})$ queries. Besides the interest in such algorithms on their own, our results limit the expected advantage of indefinite causal structures for these problems.
