title: Designing Personal Informatics Technologies for Meaningful Engagement with Experiences During Everyday Life
Creators: name: Barker, Matthew
Publisher: name: The Open University
Year: 2021

description: Responding to calls for more flexible personal informatics (PI) technologies, this thesis explores the design of experiential logging technologies, with which users can engage with the meaning of their subjective experiences during everyday life. The research it describes focused on questions concerning flexibility, minimalism and reflection in this context. It produced two prototypes to investigate these questions with users in the wild.

 First, using a technological probe with the first prototype, SpriteCatcher, the research observed that users found value and meaning through the act of expressing their experiences through colour data. Further, it suggested the need to explore whether unstructured, expressive manual logging can prompt reflection-in-the-moment. This informed a second prototype, Chromatize, which supported three different minimalist logging methods. Chromatize was used in a larger-scale, 6-week longitudinal study to better understand how flexibility and minimalism support logging and reflection, and to characterise more precisely how users reflect when using such devices.

 Together, the two studies showed that minimalist, highly flexible PI technology designs provide the means for users to dynamically engage with the aspects of life that are meaningful to them from moment to moment. The expressivity and directness of the logging interactions, and the simplicity and physical presence of the device affect when and how users engage. Drawing on substantial background literature about reflection, the thesis distinguishes between hard and soft reflection. It characterises how users might reflect when they use PI technologies, pointing to the significant role that soft reflection through manual logging can play. It concludes that the field of PI needs to expand its treatment of reflection, placing greater value on short-term, momentary day-to-day insights.

 The thesis finishes with nine design considerations that distil broad insights from the research. These can inform the design of PI technologies for meaningful engagement with experiences during everyday life.
Large Range of Stability of Larkin-Ovchinnikov States for Imbalanced Fermi Gases in Optical Lattices

description: We show that Larkin-Ovchinnikov (LO) states with modulated superfluid order parameters have a considerably larger range of stability in a lattice than in the continuum. We obtain the phase diagram for the 3D cubic attractive Hubbard model with an unequal population of up and down fermions using the Bogoliubov-de Gennes fully self-consistent method. We find a strong modulation of the local polarization that should provide a distinct signature for detection of the LO phase. The shell structure in the presence of a trap generates singularities in the density at the phase boundaries and provide additional evidence for the LO phase. Depending on specific parameters, the LO ground state occurs over a large range of population imbalance, involving 80% of the atoms in the trap, and can exist up to an entropy s ~ 0.5 k_B per fermion.

description: This volume represents a collection of papers that present some of the results of two projects on control: on the one hand, the project Typology of complement control directed by Barbara Stiebels and funded by the German Research Foundation (DFG STI 151/2-2), and on the other hand the project Variation in control structures directed by Maria Polinsky and Eric Potsdam and funded by the US National Science Foundation (NSF grants BCS-0131946, BCS-0131993; website http://accent.ucsd.edu/). Whereas the first project pursued a lexical approach to control with a semantic definition of obligatory control, the second project has mainly pursued a syntactic approach to control – with special emphasis on less studied control structures (such as adjunct control, backward control, finite control, etc.). Both projects have aimed at extending the research on complement control to structures that differ from the prototypical cases of infinitival complements with empty subjects found in many Indo-European languages; their common interest was to bring in new empirical data, both primary and experimental.

description: We study 1-loop effects for massless Dirac fields in two spatial dimensions, coupled to homogeneous electromagnetic backgrounds, both at zero and at finite temperature and density. In the case of a purely magnetic field, we analyze the relationship between the invariance of the theory under large gauge transformations, the appearance of Chern-Simons terms and of different Berry's phases. In the case of a purely electric background field, we show that the effective Lagrangian is independent of the chemical potential and of the temperature. More interesting: we show that the minimal conductivity, as predicted by the quantum field theory, is the right multiple of the conductivity quantum and is, thus, consistent with the value measured for graphene, with no extra factor of pi in the denominator.

description: Imagining a Caring Self in the Age of Post-Subjectivity. A modest Proposal
This article discusses the possibility of successfully reintroducing a notion of subjectivity of transcendental sort in the context of contemporary philosophical reflection about caring. The notion of caring revolves around a new kind of subjectivity, far from the sovereign and ultimately totalitarian subject typical of modern philosophy. Yet, as this article tries to argument, also present-day fragmented and liquid subjectivity, non-violent as it might seem, is unfit to bear the burden of the effort of imagining a new subjectivity built around caring as its core. Transcendentality – far from being necessarily implicated with violence and philosophical, as well as political, totalitarianism – may instead be non-violent and respectful of human finiteness, and therefore free from the suspect of restoring old metaphysical views about a fully sovereign subject. All of the more, it makes the notion of caring achieve an iconic status as the very coronation of ethics, in the terms of what can actually substantiate an otherwise intellectualistic (or “too metaphysical”) notion of good.

Towards a typology of complement control
Creators: name: Stiebels, Barbara
Publisher: name: ZAS Papers in Linguistics
Year: 2007

description: It is the aim of this paper to evaluate the various types of sentential complementation available in terms of complement control cross-linguistically. I will propose a lexical classification of control classes on the basis of the instantiated subordination patterns. I want to focus on an important distinction, namely that of structural vs. inherent control. Structural control is found with predicates that select a clausal complement whose structure requires argument identification and thus 'induces' control. Infinitival complements are prototypical cases for this kind of control because in most languages infinitival complements can only 'survive' in structures of control or raising. The interesting question is which predicates license structural control and which cross-linguistic differences emerge between potential licensors. Inherent control is found with predicates that require control readings independent of the instantiated structure of sentential complementation (e.g. a directive predicate such as zwingen 'force'). In addition, I will recapitulate and add arguments for the dual lexical-syntactic nature of complement control.

Politics and Gender: The Role Of Female Senator’s Power In Their Advocacy For Women’s Interest
Creators: name: Wu, Linhui
Publisher: name: University of Chicago
Year: 2023

description: Although progress has been made in increasing the representation of women in political institutions, their roles in the legislative process remains limited, and substantive representation of women's interests requires not only descriptive representation but also power and influence over the legislative process. The emergence of social media platforms provides a new space for politicians to express their political interests and spread over a wider audience. Examining senators' public rhetoric on social media can provide insights into their potential legislative interests and attention focus, and advocacy for women's interests is crucial in promoting gender equality and social justice. This study investigates whether female senators advocate more for women's interests on social media than their male counterparts and whether female senators with higher leadership roles advocate more for women's interests. However, this study finds that women with higher information control and power do not necessarily advocate for women's interests more frequently, suggesting a tension between leadership and substantive representation of women's interests. Additionally, Republican senators publish significantly fewer statements about women's interests than independent and Democratic senators. This study addresses a gap in current theories regarding the impact of women's power and status on promoting substantive representation of women in the legislative process, particularly on the advocacy for women's interests on social media platforms.
Spatial motion of the Magellanic Clouds. Tidal models ruled out?

subject: FOS: Physical sciences

description: Recently, Kallivayalil et al. derived new values of the proper motion for the Large and Small Magellanic Clouds (LMC and SMC, respectively). The spatial velocities of both Clouds are unexpectedly higher than their previous values resulting from agreement between the available theoretical models of the Magellanic System and the observations of neutral hydrogen (HI) associated with the LMC and the SMC. Such proper motion estimates are likely to be at odds with the scenarios for creation of the large-scale structures in the Magellanic System suggested so far. We investigated this hypothesis for the pure tidal models, as they were the first ones devised to explain the evolution of the Magellanic System, and the tidal stripping is intrinsically involved in every model assuming the gravitational interaction. The parameter space for the Milky Way (MW)-LMC-SMC interaction was analyzed by a robust search algorithm (genetic algorithm) combined with a fast restricted N-body model of the interaction. Our method extended the known variety of evolutionary scenarios satisfying the observed kinematics and morphology of the Magellanic large-scale structures. Nevertheless, assuming the tidal interaction, no satisfactory reproduction of the HI data available for the Magellanic Clouds was achieved with the new proper motions. We conclude that for the proper motion data by Kallivayalil et al., within their 1-sigma errors, the dynamical evolution of the Magellanic System with the currently accepted total mass of the MW cannot be explained in the framework of pure tidal models. The optimal value for the western component of the LMC proper motion was found to be pm_w(LMC) > -1.3 mas/yr in case of tidal models. It corresponds to the reduction of the Kallivayalil et al. value for pm_w(LMC) by approx. 40% in its magnitude.

In addition to their fundamental interest, our results open up new opportunities for robust optical control of matter waves.

Pesci rossi, filosofi e acrobazie. L’impossibile morale di Michel Foucault

description: Goldfishes, Philosophers and Acrobatics. Michel Foucault’s impossible Ethics.
One day, when he was a child, Foucault asked his mother: «Mom, what does a fish think?». In a way, the query that Foucault carries out on the relationship among subjectivity and truth brings back to his curiosity as a child. We will never be able to identify ourselves with a goldfish, to understand what it thinks as it swims in its aquarium. In the same way, we are not able to completely understand the way antiquity thought the relationship between the human being and the truths of ethics and politics. That is why it is worth trying to understand it and undertake the difficult acrobatics of thought that have always characterized philosophy… The meeting on cura sui at the University of Verona happens to take place in the thirtieth anniversary of Foucault’s celebrated lectures on ancient ethics, The Hermeneutics of the Subject. Therefore, a paper on the French philosopher is due. But do not expect Foucault to confirm the possibility of proposing the ethics of cura sui as valid for the present. In his last researches he shows an ambivalent attitude towards antiquity, which reveals a deep discomfort. Foucault’s last studies – although he never acknowledged it – represent the failure of his research project. Their value lies exactly in this: while observing the aquarium of the Greeks and Romans, the last Foucault came to question his whole method. In The Hermeneutics of the Subject he had to admit, in spite of himself, that in the Hellenistic age and in imperial Rome the ‘culture of the self’ froze into a universal normative morality that disclosed the Christian hermeneutic of desire and thus modern subjectivity. In the lectures at the Collège de France of the following years, he sought after the origin of an alternative tradition to which he supposed both Enlightenment and his own critical attitude belonged, and he found it not in cura sui but in parrhesia. In this way Foucault abandoned the hypothesis that different historical systems of thought are incommensurable, and he ascertained that from the beginning – at least in the Western tradition – subjectivity is compelled to make a choice between an epistemic and an ethical approach to truth, between the will to knowledge and the will to freedom. In so doing, he opened a new field of research, which this conference contributes to develop and further. …At the end human beings are note one another as goldfish, even when they belongs to different historical systems of thought.

Dark matter and neutrino masses in the R-parity violating NMSSM

description: The R-Parity symmetry Violating (RPV) version of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) is attractive simultaneously with regard to the so-called mu-problem and the accommodation of three-flavor neutrino data at tree level. In this context, we show here that if the Lightest Supersymmetric Particle (LSP) is the gravitino, it possesses a lifetime larger than the age of the universe since its RPV induced decay channels are suppressed by the weak gravitational strength. This conclusion holds if one considers gravitino masses ~ 10^2 GeV like in supergravity scenarios, and is robust if the lightest pseudoscalar Higgs field is as light as ~ 10 GeV [as may occur in the NMSSM]. For these models predicting in particular an RPV neutrino-photino mixing, the gravitino lifetime exceeds the age of the universe by two orders of magnitude. However, we find that the gravitino cannot constitute a viable dark matter candidate since its too large RPV decay widths would then conflict with the flux data of last indirect detection experiments. The cases of a sneutrino LSP or a neutralino LSP as well as the more promising gauge-mediated supersymmetry breaking scenario are also discussed. Both the one-flavor simplification hypothesis and the realistic scenario of three neutrino flavors are analyzed. We have modified the NMHDECAY program to extend the neutralino mass matrix to the present framework.

description: Repurposing of approved drugs that target host functions also important for virus replication promises to overcome the shortage of antiviral therapeutics. Mostly, virus biology including initial screening of antivirals is studied in conventional monolayer cells. The biology of these cells differs considerably from infected tissues. 3D culture models with characteristics of human tissues may reflect more realistically the in vivo events during infection. We screened first, second, and third generation epidermal growth factor receptor (EGFR)-inhibitors with different modes of action and the EGFR-blocking monoclonal antibody cetuximab in a 3D cell culture infection model with primary human keratinocytes and cowpox virus (CPXV) for antiviral activity. Antiviral activity of erlotinib and osimertinib was nearly unaffected by the cultivation method similar to the virus-directed antivirals tecovirimat and cidofovir. In contrast, the host-directed inhibitors afatinib and cetuximab were approx. 100-fold more efficient against CPXV in the 3D infection model, similar to previous results with gefitinib. In summary, inhibition of EGFR-signaling downregulates virus replication comparable to established virus-directed antivirals. However, in contrast to virus-directed inhibitors, in vitro efficacy of host-directed antivirals might be seriously affected by cell cultivation. Results obtained for afatinib and cetuximab suggest that screening of such drugs in standard monolayer culture might underestimate their potential as antivirals.
Encoding focus in Kanuri verbal morphology: predication focus and the "Kanuri focus shift"

Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Focus on verbal operators such as aspect or tense ("predication focus", lucidly described by Hyman & Watters (1984) under the label "auxiliary focus") has been noticed to exist in African languages of Afroasiatic and Niger-Congo affiliation, but not so far in Saharan. The Saharan language Kanuri is assumed to have substantially reorganized its TAM system, particularly in the perfective aspect domain (Cyffer [2006] dates major changes between the years 1820 and 1900). The paper discusses, for the first time in Kanuri scholarship, the existence of a neat subsystem of predication focus marking by suffix in the perfective aspect which is made up of a total of six conjugational paradigms that uniformly encode predication focus by suffix {-ò}. Kanuri dialects differ in strategies and scope of focus marking encoded in verb morphology. In the light of data from the Yerwa (Nigeria) and Manga (Niger) dialects the paper discusses some "anomalies" with regard to general focus theory which we account for by describing the "Kanuri Focus Shift" as a diachronic process which is responsible for leftward displacement of scope of focus.

description: A GL(2, R) structure on an (n+1)-dimensional manifold is a smooth pointwise identification of tangent vectors with polynomials in two variables homogeneous of degree n. This, for even n=2k, defines a conformal structure of signature (k, k+1) by specifying the null vectors to be the polynomials with vanishing quadratic invariant. We focus on the case n=6 and show that the resulting conformal structure in seven dimensions is compatible with a conformal G_2 structure or its non-compact analogue. If a GL(2, R) structure arises on a moduli space of rational curves on a surface with self-intersection number 6, then certain components of the intrinsic torsion of the G_2 structure vanish. We give examples of simple 7th order ODEs whose solution curves are rational and find the corresponding G_2 structures. In particular we show that Bryant's weak G_2 holonomy metric on the homology seven-sphere SO(5)/SO(3) is the unique weak G_2 metric arising from a rational curve.

description: Know your star, know your planet: The K2-18 planetary system as an example

 J. Maldonado, G. Micela
 In this contribution we show how small changes in the stellar
 parameters of the host stars might have a significant impact in the
 determination of the planetary bulk composition using the star K2-18
 as a test case. K2-18 is an early-M dwarf, known to harbour a
 transiting super-Earth as well as a second non transiting planet. We
 compiled several datasets of stellar parameters for the host star and
 computed the masses of the planets using the available radial
 velocity data. For planet b, the planetary radius and density were
 also computed. We find that smaller stellar mass and radius
 translates into a higher overall density leading to a significantly
 different planetary composition. We analyse the origin of the
 differences in the published values of mass and radius for K2-18
 finding that different mass-luminosity relationships can provide
 significantly different stellar and planetary properties.

description: This paper concerns the distribution of wh-words in Asante Twi, which has both a focus fronting strategy and an in-situ strategy. We show that the focusing and the in-situ constructions are not simply equally available options. On the contrary, there are several cases where the focusing strategy must be used and the in-situ strategy is ungrammatical. We show that the cases in Asante Twi are "intervention effects", which are attested in other languages, like German, Korean, and French. We identify a core set of intervening elements that all of these languages have and discuss their properties.

description: We investigate a model of transportation networks with nonlinear elements which may represent local shortage of resources. Frustrations arise from competition for resources. When the initial resources are uniform, different regimes with discrete fractions of satisfied nodes are observed, resembling the Devil's staircase. We demonstrate how functional recursions are converted to simple recursions of probabilities. Behavior similar to those in the vertex cover or close packing problems are found. When the initial resources are bimodally distributed, increases in the fraction of rich nodes induce a glassy transition, entering an algorithmically hard regime.

Subjects: Riccardo Panattoni; orizzontalità; verticalità;

description: Horizontal; vertical; anthropological coordinates
In this article we will consider “horizontal” and “vertical” not as given topographic references, but as anthropological co-ordinates that are capable to shape the existence of human beings. Whenever we “climb up”, i.e. whenever we raise ourselves to such a height that we are finally capable to broaden our horizons, as a matter of fact we invariably fall into the danger of considering such rising to the top as a sort of conquest. As a consequence, in this rise we are often followed and haunted by the fear of ruin because of our misplaced ambitions, or to be dispossessed of our achievements by someone else who aspires to that same position and dignity. Therefore, when considering these important anthropological dimensions of “horizontal” and “vertical”, it comes out that our main worry should be to keep the “top” and the “base” constantly in touch: in this way, the weakening of our trust in decisional power would become a way to solve existential challenges and to favor a different way of acting and enacting, centered around the power-free criteria of a hesitant contemplative mood.

description: We apply a recently developed renormalization group (RG) method to study synchronization in a one-dimensional chain of phase-coupled oscillators in the regime of weak randomness. The RG predicts how oscillators with randomly distributed frequencies and couplings form frequency-synchronized clusters. Although the RG was originally intended for strong randomness, i.e. for distributions with long tails, we find good agreement with numerical simulations even in the regime of weak randomness. We use the RG flow to derive how the correlation length scales with the width of the coupling distribution in the limit of large coupling. This leads to the identification of a universality class of distributions with the same critical exponent $ν$. We also find universal scaling for small coupling. Finally, we show that the RG flow is characterized by a universal approach to the unsynchronized fixed point, which provides physical insight into low-frequency clusters.

description: We present a multiwavelength analysis of a sample of four hot (T_X>8keV) X-ray galaxy clusters (A1689, A2261, A2142, and A2390) using joint AMiBA Sunyaev-Zel'dovich effect (SZE) and Subaru weak lensing observations, combined with published X-ray temperatures, to examine the distribution of mass and the intracluster medium (ICM) in massive cluster environments. Our observations show that A2261 is very similar to A1689 in terms of lensing properties. Many tangential arcs are visible around A2261, with an effective Einstein radius \sim 40 arcsec (at z \sim 1.5), which when combined with our weak lensing measurements implies a mass profile well fitted by an NFW model with a high concentration c_{vir} \sim 10, similar to A1689 and to other massive clusters. The cluster A2142 shows complex mass substructure, and displays a shallower profile (c_{vir} \sim 5), consistent with detailed X-ray observations which imply recent interaction. The AMiBA map of A2142 exhibits an SZE feature associated with mass substructure lying ahead of the sharp north-west edge of the X-ray core suggesting a pressure increase in the ICM. For A2390 we obtain highly elliptical mass and ICM distributions at all radii, consistent with other X-ray and strong lensing work. Our cluster gas fraction measurements, free from the hydrostatic equilibrium assumption, are overall in good agreement with published X-ray and SZE observations, with the sample-averaged gas fraction of = 0.133 \pm 0.027, for our sample = (1.2 \pm 0.1) \times 10^{15} M_{sun} h^{-1}. When compared to the cosmic baryon fraction f_b = Ω_b/Ω_m constrained by the WMAP 5-year data, this indicates /f_b = 0.78 \pm 0.16, i.e., (22 \pm 16)% of the baryons are missing from the hot phase of clusters.

This paper investigates presupposition, exhaustivity effects, and felicity conditions in some of its attested forms. Yorùbá focus does not trigger existence presuppositions, it does not have any obligatory exhaustivity effects, and argument focus and predicate focus behave differently with respect to question-answer congruence. These properties are compatible Déchaine’s analysis (2002) of Yorùbá focus as inverse predication, essentially a type of cleft.

Focus in an active/agentive alignment system: the case of Beria (Saharan)
Creators: name: Jakobi, Angelika
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Beria, a member of the Saharan language family, is one of the rare languages in Africa exhibiting both an ergative and an active/agentive alignment system of grammatical relations.1 While the active/agentive pattern is shown by the participant reference markers, the ergative pattern is attested both in the constituent order and in the focus markers on the core constituents. In the pragmatically unmarked constituent order, the Agent constituent precedes the Patient constituent. An unmarked single constituent immediately preceding the verb may represent a Patient or a Subject argument. In this position, the Agent constituent requires the clitic GU. The focused Patient and Subject constituents are both either marked by the clitic DI or by a cleft construction.

description: A few-electron double quantum dot was fabricated using metal-oxide-semiconductor(MOS)-compatible technology and low-temperature transport measurements were performed to study the energy spectrum of the device. The double dot structure is electrically tunable, enabling the inter-dot coupling to be adjusted over a wide range, as observed in the charge stability diagram. Resonant single-electron tunneling through ground and excited states of the double dot was clearly observed in bias spectroscopy measurements.

description: La fórmula E = mc^2, creada por Jorge Diaz-Crespo Valdés, ampliamente conocida como la fórmula de equivalencia masa-energía, ha sido considerada durante mucho tiempo como la fórmula para calcular la energía. Sin embargo, esta fórmula solo se aplica a sistemas cerrados en reposo o en movimiento, y no tiene en cuenta otras formas de energía que no están relacionadas con la masa. En este informe, se presenta la fórmula E = OM^2 como una fórmula precisa para calcular la energía generada por la materia excitada. Esta fórmula tiene en cuenta la frecuencia de la onda de vacío que excita la materia y el tipo de materia excitada. La fórmula E = OM^2 es una fórmula comprimida que expresa la relación entre la energía generada por la materia excitada, la frecuencia de la onda de vacío que la excita y la materia excitada por la frecuencia de la onda de vacío. Teniendo en cuenta que la fórmula E = mc^2, conocida como la fórmula de equivalencia masa-energía, no es suficiente para calcular la energía en todas las situaciones. En su lugar, se propone la fórmula E = OM^2, que tiene en cuenta la frecuencia de la onda de vacío que excita la materia y el tipo de materia excitada. Esta fórmula expresa la relación entre la energía generada por la materia excitada, la frecuencia de la onda de vacío y la materia excitada por la frecuencia de la onda de vacío, a diferencia de E = mc^2 que solo expresa la relación entre la masa y la energía de la materia sin tener en cuenta otras fuentes de energía
Syntactic focus marking in Khoekhoe ("Nama/Damara")
Creators: name: Haacke, Wilfrid H. G.
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Khoekhoe syntax exhibits an unusually flexible constituent structure. Any constituent with a lexical head can be preposed into the focal initial slot immediately before the PGN-marker that marks the subject position. Two strategies of focalisation by foregrounding need to be distinguished: inversion and fronting. Inversion amounts to an inversion of subject and predicate in their entirety. Such sentences have two readings, though, according to their underlying constituent structure: "predicative" or "copulative". Fronting amounts to the preposing of a lexical constituent into the focal initial slot, with subsequent dislocation of the lexical specification of the subject from that slot. The present analysis has wider implications, particularly: The generally accepted view that Khoekhoe has coreferential/equational "copulative" sentences of the type NPsubject = NPcomplement is a fallacy. Such sentences actually are sentences with their predicate fronted into the focal initial slot. They amount to cleft constructions. The fact that the primary focal position is immediately before the PGNmarker of the subject is further independent evidence for the "desentential hypothesis", according to which subject and object NPs in the underlying matrix sentence consist of only an enclitic PGN-marker, and for the claim that Khoekhoe underlyingly is a SVO language, not a SOV language as generally held. By implication these findings affect the analysis of other Central Khoesaan languages.

Finding and counting vertex-colored subtrees
Creators: name: Guillemot, Sylvain
name: Sikora, Florian
Publisher: name: arXiv
Year: 2010
Subjects: subject: Computational Complexity (cs.CC)
subject: FOS: Computer and information sciences

description: The problems studied in this article originate from the Graph Motif problem introduced by Lacroix et al. in the context of biological networks. The problem is to decide if a vertex-colored graph has a connected subgraph whose colors equal a given multiset of colors $M$. It is a graph pattern-matching problem variant, where the structure of the occurrence of the pattern is not of interest but the only requirement is the connectedness. Using an algebraic framework recently introduced by Koutis et al., we obtain new FPT algorithms for Graph Motif and variants, with improved running times. We also obtain results on the counting versions of this problem, proving that the counting problem is FPT if M is a set, but becomes W[1]-hard if M is a multiset with two colors. Finally, we present an experimental evaluation of this approach on real datasets, showing that its performance compares favorably with existing software.

Quantum waveguide theory of Andreev reflection in multiband superconductors: the case of Fe-pnictides
Creators: name: Araujo, M. A. N.
name: Sacramento, P. D.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The problem of Andreev reflection between a normal metal and a multiband superconductor is addressed. The appropriate matching conditions for the wave function at the interface are established on the basis of an extension of quantum waveguide theory to these systems. Interference effects between different bands of the superconductor manifest themselves in the conductance and the case of FeAs superconductors is specifically considered, in the framework of a recently proposed effective two-band model, in the sign-reversed s-wave pairing scenario. Resonant transmission through surface Andreev bound states is found as well as destructive interference effects that produce zeros in the conductance at normal incidence. Both these effects occur at nonzero bias voltage.

Unitary equilibrations: probability distribution of the Loschmidt echo
Creators: name: Venuti, Lorenzo Campos
name: Zanardi, Paolo
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Closed quantum systems evolve unitarily and therefore cannot converge in a strong sense to an equilibrium state starting out from a generic pure state. Nevertheless for large system size one observes temporal typicality. Namely, for the overwhelming majority of the time instants, the statistics of observables is practically indistinguishable from an effective equilibrium one. In this paper we consider the Loschmidt echo (LE) to study this sort of unitary equilibration after a quench. We draw several conclusions on general grounds and on the basis of an exactly-solvable example of a quasi-free system. In particular we focus on the whole probability distribution of observing a given value of the LE after waiting a long time. Depending on the interplay between the initial state and the quench Hamiltonian, we find different regimes reflecting different equilibration dynamics. When the perturbation is small and the system is away from criticality the probability distribution is Gaussian. However close to criticality the distribution function approaches a double peaked, "batman-hood" shaped, universal form.

Argument focus in Kar (Senufo)
Creators: name: Dombrowsky-Hahn, Klaudia
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Focus theories distinguish different types of focus according to the pragmatic conditions or communicative point on the one side and different scopes of focus on the other side. The assertion in term focus constructions (Dik 1989), called by others argument focus constructions or identificational sentences (Lambrecht 1994), has the purpose of establishing a relation between an argument and an open proposition. Kar, a north-eastern Senufo language of Burkina Faso, which has the basic word order S-Aux-O-V-other, has at its disposal different strategies to mark argument focus, among them fronting of the focused item. In many West African languages the displacement of the focused argument involves other devices, such as the use of special verb forms. In Kar fronting of a focused argument requires the use of special pronouns in the out-of-focus part of the sentence, called background subject pronouns. They are used in other backgrounded contexts, too, for example in relative clauses, adverbial clauses and constituent questions. Their inconsistent use is attributed to a particular sociolinguistic situation in which the data has been collected. The use of the same focus strategies for completive and contrastive focus suggests that Kar does not distinguish pragmatic conditions on the level of sentence grammar.

Condition, topic and focus in African languages: why conditionals are not topics
Creators: name: Caron, Bernard
Publisher: name: ZAS Papers in Linguistics
Year: 2006

description: Since Haiman (1978), a general assumption concerning the information structure of conditional sentences is that "conditionals are topics". However, in Chadic South Bauchi West languages spoken in Northern Nigeria, as well as in Banda Linda, an Adamawa language spoken in the République Centre-Africaine, conditionals share their structure with focus, not topic. This seriously questions Haiman’s claim and forces us to reconsider the facts and characterizations of conditionals, topic and focus in general. In order to do this, we will first examine the facts of conditionals in some Chadic languages, then their information structure. We will see how both data and theory invalidate Haiman's claim. Then we will see that if they are not topics, they are different from focus as well. We will argue that if the elements which make a topic or a focus can appear in conditionals, these must be separated from what constitutes the identity of conditions. Then, we will see if these can be characterized in the same way as Lambrecht characterizes temporal clauses, viz. as "activated propositions" (Lambrecht 1994). We will finally conclude that they should rather be defined as "fictitious assertions" (Culioli 2000).
