description: A democratização do acesso as tecnologias da informação e comunicação e a emergência de plataformas que privilegiam a publicação de conteúdos e a socialização dos indivíduos, fez nascer um novo tipo de consumidor de informação, agora também produtor. O resultado deste novo papel, normalmente designado por Conteúdo Gerado pelos Utilizadores e um fenómeno relativamente recente, mas que, graças a ubiquidade da tecnologia, se tem vindo a espalhar, apesar de o comportamento da maioria dos indivíduos na Web ser orientado por outras motivações, nomeadamente a da comunicação. O conteúdo produzido e multiforme, apresenta diversos níveis de granularidade, pode ser original, derivado ou resultar de uma remistura, e produzido individualmente ou de forma cooperativa em plataformas que apelam a socialização, e nas quais poucos indivíduos são grandes produtores e a grande maioria contribuintes esporádicos. A utilização destes conteúdos pela comunidade parece obedecer também a uma constante que se traduz no consumo dos mesmos, poucos, conteúdos por um grande numero e numa popularidade diminuta de muitos, o que, apesar disso, não deixa de constituir uma nova possibilidade de atingir um numero diversificado de pequenos nichos. Os problemas da originalidade, privacidade e qualidade são os que mais recorrentemente ocorrem na discussão da outra face desta moeda. As bibliotecas tem vindo timidamente a aceitar estes novos produtores, abrindo mesmo a sua participação os instrumentos de organização e recuperação de informação que, historicamente, eram só seus, mas demonstrando alguma dificuldade na assunção do papel de produtoras, em cooperação, de novos conteúdos, que não os do domínio tradicional da meta-informação. A discussão a volta de questões como da organização, recuperação e preservação destes conteúdos da os primeiros passos, bem como a da gestão destas comunidades de utilizadores/produtores. No entanto, esta e uma realidade que não e possível ignorar e espera-se que este contributo possa servir para lançar a discussão e a investigação na comunidade das bibliotecas portuguesas.

Coupling of quantum-dot states via elastic-cotunneling and crossed Andreev reflection in a minimal Kitaev chain

description: Recently, exciting progress has been made in using the superconducting nanowires coupled to gate-defined quantum dots (QDs) to mimic the Kiteav chain and realize the Majorana-bound states via a poor man's route. The essential ingredient is to balance the interdot elastic-cotunneling (ECT) and crossed Andreev reflection (CAR). As theoretically proposed, this can be mediated by the Andreev bound states (ABSs) formed in the superconducting nanowires. However, most of the gate-tuning asymmetric features observed in experiments can not be captured using the current theoretical models. To address this insufficiency, here, we consider a full model that explicitly includes all the details of both the QD states and the ABSs. Remarkable agreement is found with the recent experimental observations, where our model correctly reveals the gate-tuning asymmetry in ECTs and by which the average QD state energy can also be extracted. In contrast, CARs do not depend on the tuning of QD states. Moreover, armed with the tunability of ECTs and CARs with QD states, we also predict a controllable anisotropic superexchange interaction between electron spins in the two separated QDs.
A de Finetti theorem for quantum causal structures

description: What does it mean for a causal structure to be `unknown'? Can we even talk about `repetitions' of an experiment without prior knowledge of causal relations? And under what conditions can we say that a set of processes with arbitrary, possibly indefinite, causal structure are independent and identically distributed? Similar questions for classical probabilities, quantum states, and quantum channels are beautifully answered by so-called "de Finetti theorems", which connect a simple and easy-to-justify condition -- symmetry under exchange -- with a very particular multipartite structure: a mixture of identical states/channels. Here we extend the result to processes with arbitrary causal structure, including indefinite causal order and multi-time, non-Markovian processes applicable to noisy quantum devices. The result also implies a new class of de Finetti theorems for quantum states subject to a large class of linear constraints, which can be of independent interest.

description: High energy elastic pp differential cross section at LHC at the c.m. energy 14 TeV is predicted using the asymptotic behavior of sigma-tot(s) and rho(s), and the measured pbar-p differential cross section at sqrt{s}=546 GeV. The phenomenological investigation has progressively led to an effective field theory model that describes the nucleon as a chiral bag embedded in a quark-antiquark condensed ground state. The measurement of pp elastic scattering at LHC up to large |t| >~ 10 GeV^2 by the TOTEM group will be crucial to test this structure of the nucleon.

description: We give a new proof of a theorem of Zudilin that equates a very-well-poised hypergeometric series and a particular multiple integral. This integral generalizes integrals of Vasilenko and Vasilyev which were proposed as tools in the study of the arithmetic behaviour of values of the Riemann zeta function at integers. Our proof is based on limiting cases of a basic hypergeometric identity of Andrews.

description: Multiphase field models have emerged as an important computational tool for understanding biological tissue while resolving single-cell properties. While they have successfully reproduced many experimentally observed behaviors of living tissue, the theoretical underpinnings have not been fully explored. We show that a two-dimensional version of the model, which is commonly employed to study tissue monolayers, can be derived from a three-dimensional version in the presence of a substrate. We also show how viscous forces, which arise from friction between different cells, can be included in the model. Finally, we numerically simulate a tissue monolayer, and find that intercellular friction tends to solidify the tissue.

Bifurcations of inflating balloons and interacting hysterons

description: While many materials exhibit a complex, hysteretic response to external driving, there has been a surge of interest in how the complex dynamics of internal materials states can be understood and designed to process and store information. We consider a system of connected rubber balloons that can be described by a Preisach model of non-interacting hysterons under pressure control, but for which the hysterons become coupled under volume control. We study this system by exploring the possible transition graphs, as well as by introducing a configuration space approach which tracks the volumes of each balloon. Changes in the transition graphs turn out to be related to changes in the topology of the configuration space of the balloons, providing a particularly geometric view of how transition graphs can be designed, as well as additional information on the existence of hidden metastable states. This class of systems is more general than just balloons.

description: Based on the experimental observation, that only the close vicinity of a magnetic impurity at metal surfaces determines its Kondo behaviour, we introduce a simple model which explains the Kondo temperatures observed for cobalt adatoms at the (111) and (100) surfaces of Cu, Ag, and Au. Excellent agreement between the model and scanning tunneling spectroscopy (STS) experiments is demonstrated. The Kondo temperature is shown to depend on the occupation of the d-level determined by the hybridization between adatom and substrate with a minimum around single occupancy.

description: We investigate the real-time estimation of human situation awareness using observations from a robot teammate with limited visibility. In human factors and human-autonomy teaming, it is recognized that individuals navigate their environments using an internal mental simulation, or mental model. The mental model informs cognitive processes including situation awareness, contextual reasoning, and task planning. In teaming domains, the mental model includes a team model of each teammate's beliefs and capabilities, enabling fluent teamwork without the need for explicit communication. However, little work has applied team models to human-robot teaming. In this work we compare the performance of two models, logical predicates and large language models, at estimating user situation awareness over varying visibility conditions. Our results indicate that the methods are largely resilient to low-visibility conditions in our domain, however opportunities exist to improve their overall performance.

description: Fractal Interpolation has been proposed in the literature as an efficient way to construct closure models for the numerical solution of coarse-grained Navier-Stokes equations. It is based on synthetically generating a scale-invariant subgrid-scale field and analytically evaluating its effects on large resolved scales. In this paper, we propose an extension of previous work by developing a multiaffine fractal interpolation scheme and demonstrate that it preserves not only the fractal dimension but also the higher-order structure functions and the non-Gaussian probability density function of the velocity increments. Extensive a-priori analyses of atmospheric boundary layer measurements further reveal that this Multiaffine closure model has the potential for satisfactory performance in large-eddy simulations. The pertinence of this newly proposed methodology in the case of passive scalars is also discussed.

description: A topological space X$ has the Frechet-Urysohn property if for each subset A of X and each element x in the closure of A, there exists a countable sequence of elements of A which converges to x. Reznichenko introduced a natural generalization of this property, where the converging sequence of elements is replaced by a sequence of disjoint finite sets which eventually intersect all neighborhoods of x. In their paper, Kocinac and Scheepers conjecture that the minimal cardinality of a set X of real numbers such that C_p(X) does not have the weak Frechet-Urysohn property is equal to b. (b is the minimal cardinality of an unbounded family in the Baire space). We prove the Kocinac-Scheepers conjecture by showing that if C_p(X) has the Reznichenko property, then a continuous image of X cannot be a subbase for a non-feeble filter on the natural numbers.

description: Parkinson's disease (PD) is a common neurodegenerative disorder with a poorly understood physiopathology and no established biomarkers for the diagnosis of early stages and for prediction of disease progression. Several neuroimaging biomarkers have been studied recently, but these are susceptible to several sources of variability related for instance to cohort selection or image analysis. In this context, an evaluation of the robustness of such biomarkers to variations in the data processing workflow is essential. This study is part of a larger project investigating the replicability of potential neuroimaging biomarkers of PD. Here, we attempt to reproduce (re-implementing the experiments with the same data, same method) and replicate (different data and/or method) the models described in [1] to predict individual's PD current state and progression using demographic, clinical and neuroimaging features (fALFF and ReHo extracted from resting-state fMRI). We use the Parkinson's Progression Markers Initiative dataset (PPMI, ppmi-info.org), as in [1] and aim to reproduce the original cohort, imaging features and machine learning models as closely as possible using the information available in the paper and the code. We also investigated methodological variations in cohort selection, feature extraction pipelines and sets of input features. Different criteria were used to evaluate the reproduction and compare the reproduced results with the original ones. Notably, we obtained significantly better than chance performance using the analysis pipeline closest to that in the original study (R2 \> 0), which is consistent with its findings. Moreover, using derived data provided by the authors of the original study, we were able to make an exact reproduction and managed to obtain results that were close to the original ones. The challenges encountered while reproducing and replicating the original work are likely explained by the complexity of neuroimaging studies, in particular in clinical settings. We provide recommendations to further facilitate the reproducibility of such studies in the future.

Com este número duplo pretendemos recuperar – mesmo não tendo ainda passado um ano sobre a posse deste Conselho Diretivo – um atraso de três anos na edição de CADERNOS. Aproveitando uma sugestão do anterior Conselho Editorial, que solidariamente se manteve em funções, estabelecemos contatos com os organizadores das Conferências do Cenáculo realizadas em Évora em 2010 e conseguimos reunir os textos das comunicações apresentadas a esse encontro científico sobre “A Biblioteca 2.0”, tema que consideramos de grande interesse e atualidade. Como em 2010 se assinalou o 2.º centenário do nascimento de Alexandre Herculano, apresentamos um texto sobre esta grande figura da nossa cultura, que também foi bibliotecário e arquivista, pois entendemos que a esta revista compete igualmente manter viva a memória e a história das nossas bibliotecas e arquivos e daqueles que nelas trabalharam. Neste número evocamos ainda, sentidamente, dois colegas que marcaram a nossa profissão e tão precocemente nos deixaram – Joaquim Mestre e Isabel Sousa. Apesar das dificuldades com que a BAD se debate enquanto associação, é nossa firme intenção manter a regularidade da publicação de CADERNOS BAD, que, porém, terá que ter, pelo menos nos tempos mais próximos, periodicidade anual. Já estamos a organizar o número relativo a 2011, pensando que, tal como este… vai valer a pena!

description: We employ concepts and tools from the theory of finite permutation groups in order to analyse the Hidden Subgroup Problem via Quantum Fourier Sampling (QFS) for the symmetric group. We show that under very general conditions both the weak and the random-strong form (strong form with random choices of basis) of QFS fail to provide any advantage over classical exhaustive search. In particular we give a complete characterisation of polynomial size subgroups, and of primitive subgroups, that can be distinguished from the identity subgroup with the above methods. Furthermore, assuming a plausible group theoretic conjecture for which we give supporting evidence, we show that weak and random-strong QFS for the symmetric group have no advantage whatsoever over classical search.

Amblyornis subalaris germanus Rothschild, 1910a: 13 (Rawlinson Mountains, German New Guinea).
Now Amblyornis germana Rothschild, 1910. See Hartert, 1928: 190; Mayr, 1941: 184; Gilliard, 1969: 300–311; Coates, 1990: 392–397; Coates and Peckover, 2001: 209; Dickinson, 2003: 427; and Frith and Frith, 2004: 275–278; 2009a: 394– 395.
HOLOTYPE: AMNH 679570, [adult female], collected in the Rawlinson Mountains, 06.32S, 147.17E (Frith and Beehler, 1998: 570), Huon Peninsula, Morobe Province, Papua New Guinea (once part of German New Guinea), undated, obtained from Professor F. Foerster. From the Rothschild Collection.
COMMENTS: When Rothschild described this form, he had the single complete specimen in female plumage, which he designated as the type, and mentioned that he also had the crest only of a male. The paratype is AMNH 679571, crest of male obtained ‘‘From natives.’’ A complete male specimen was obtained only after the publication of germana.
Coates and Peckover (2001: 209) suggest- ed, based on its shorter crest and very distinctive bower, that this form should perhaps be given species status and, having seen the bower myself, I agree.

title: A survey of the wind energy resource of Cornwall to examine the influence of settlement patterns and topography on optimum wind turbine size and disposition
Creators: name: Williams, Geoffrey J
Publisher: name: The Open University
Year: 1989

description: The introduction of wind turbines has led to complaints about noise, domination and radio frequency interference from neighbouring properties. The aim of the thesis was to determine how the pattern of rural settlement and topography influences the gross technical resource, and how this resource is affected by various combinations of wind turbine size, type and cluster layout. The work consisted of examining in detail every possible site in Cornwall and every large site in England and Wales. This involved establishing a computer data base where each location was described by over three dozen relevant site characteristics. In determining mean annual site wind speeds at hub height the data from twentysix meteorological stations and the results of over fifty Tala kite ascents were used to calibrate four predictive models for site wind speed and to choose the best one for this thesis. Five noise prediction models were tested against field results for twentytwo wind turbines. All the models were found to be inaccurate and a new prediction method with an accuracy of +/— 3^B(A) was developed. A public perception survey of over sixty households situated near six UK , wind turbines, and an examination of the way in which the 1974 Control of Pollution Act and planning policies are put into effect, both further defined acceptable environmental criteria for wind turbines. Noise and dominance were found to be the most serious restraints, whilst radio frequency interference eliminated over 40% of potential sites. The thesis shows that the resource is inversely related to wind turbine size. In Cornwall, the technical resource is 2.5MW for multimegawatt machines rising to 1555KW for quiet machines of 17m to 19m diameter.

description: Schubert polynomials are polynomial representatives of Schubert classes in the cohomology of the complete flag variety and have a combinatorial formulation in terms of bumpless pipe dreams. Quantum double Schubert polynomials are polynomial representatives of Schubert classes in the torus-equivariant quantum cohomology of the complete flag variety, but no analogous combinatorial formulation had been discovered. We introduce a generalization of the bumpless pipe dreams called quantum bumpless pipe dreams, giving a novel combinatorial formula for quantum double Schubert polynomials as a sum of binomial weights of quantum bumpless pipe dreams. We give a bijective proof for this formula by showing that the sum of binomial weights satisfies a defining transition equation.

description: The role of commensurability and the interplay of correlated disorder and interactions on vortex dynamics in the presence of columnar pins is studied via molecular dynamics simulations. Simulations of dynamics reveal substantial caging effects and a non-monotonic dependence of the critical current with enhancements near integer values of the matching field $B_ϕ$ and $3B_ϕ$ in agreement with experiments on the cuprates. We find qualitative differences in the phase diagram for small and large values of the matching field.

Fractional Energy Loss and Centrality Scaling

description: The phenomenon of centrality scaling in the high-\pt spectra of $π^0$ produced in Au-Au collisions at $\sqrt s=200$ GeV is examined in the framework of relating fractional energy loss to fractional centrality increase. A new scaling behavior is found where the scaling variable is given a power-law dependence on $N_{\rm part}$. The exponent $γ$ specifies the fractional proportionality relationship between energy loss and centrality, and is a phenomenologically determined number that characterizes the nuclear suppression effect. The implication on the parton energy loss in the context of recombination is discussed.

Did Massive Primordial Stars Preenrich the Lyman Alpha Forest?

description: We examine the dynamical evolution and statistical properties of the supernova ejecta of massive primordial stars in a cosmological framework to determine whether this first population of stars could have enriched the universe to the levels and dispersions seen by the most recent observations of the Lyman-Alpha forest. We evolve a lambda CDM model in a 1 Mpc^3 volume to a redshift of z = 15 and add ``bubbles'' of metal corresponding to the supernova ejecta of the first generation of massive stars in all dark matter halos with masses greater than 5 times 10^5 solar masses. These initial conditions are then evolved to z = 3 and the distribution and levels of metals are compared to observations. In the absence of further star formation the primordial metal is initially contained in halos and filaments. Photoevaporation of metal-enriched gas due to the metagalactic ultraviolet background radiation at the epoch of reionization (z ~ 6) causes a sharp increase of the metal volume filling factor. At z = 3, ~ 2.5% of the simulation volume (approx. 20% of the total gas mass) is filled with gas enriched above a metallicity of 10^-4 Z_solar, and less than 0.6% of the volume is enriched above a metallicity of 10^-3 Z_solar. This suggests that, even with the most optimistic prescription for placement of primordial supernova and the amount of metals produced by each supernova, this population of stars cannot entirely be responsible for the enrichment of the Lyman-$α$ forest to the levels and dispersions seen by current observations unless we have severely underestimated the duration of the Pop III epoch. However, comparison to observations show that Pop III supernovae can be significant contributors to the very low overdensity Lyman-Alpha forest.

description: Biological systems are typically dependent on transportation networks for the efficient distribution of resources and information. Revealing the decentralized mechanisms underlying the generative process of these networks is key in our global understanding of their functions and is of interest to design, manage and improve human transport systems. Ants are a particularly interesting taxon to address these issues because some species build multi-sink multi-source transport networks analogous to human ones. Here, by combining empirical field data and modelling at several scales of description, we show that pre-existing mechanisms of recruitment with positive feedback involved in foraging can account for the structure of complex ant transport networks. Specifically, we find that emergent group-level properties of these empirical networks, such as robustness, efficiency and cost, can arise from models built on simple individual-level behaviour addressing a quality-distance trade-off by the means of pheromone trails. Our work represents a first step in developing a theory for the generation of effective multi-source multi-sink transport networks based on combining exploration and positive reinforcement of best sources.

description: We present the results of a long-term monitoring campaign of the Hαline in a sample of bright OB-supergiants (O7.5-B9) that aims at detecting rotationally modulated changes potentially related to the existence of large-scale wind structures. A total of 22 objects were monitor ed during 36 nights spread over 6 months in 2001-2002. Coordinated broad-band photometric observations were also obtained for some targets. Conspicuous evidence for variability in Hαis found for the stars displaying a feature contaminated by wind emission. Most changes take place on a daily time-scale, although hourly variations are also occasionally detected. Convincing evidence for a cyclical pattern of variability in Hαhas been found in 2 stars: HD 14134 and HD 42087 (periodic signals are also detected in other stars, but independent confirmation is required). Rotational modulation is suggested from the similarity between the observed recurrence time-scales (in the range 13-25 days) and estimated periods of stellar rotation. We call attention to the atypical case of HD 14134 which exhibits a clear 12.8-d periodicity both in the photometric and in the spectroscopic data sets. This places this object among a handful of early-type stars where one may observe a clear link between extended wind structures and photospheric disturbances. Further modelling may test the hypothesis that azimuthally-extended wind streams are responsible for the patterns of spectral variability in our target stars.

description: Over the last few years, primordial black holes (PBHs) have emerged as a strong candidate for cold dark matter. A significant number of PBHs are produced when the strength of the primordial scalar power spectrum is enhanced on small scales (compared to the COBE normalized values on large scales). Such primordial spectra also inevitably lead to strong amplification of the scalar-induced, secondary gravitational waves (GWs) at higher frequencies. The recent detection of the stochastic gravitational wave background (SGWB) by the pulsar timing arrays (PTAs) has opened up the possibility of directly probing the very early universe. Different studies have shown that, when PBHs are assumed to have been formed during the epoch of radiation domination, the mechanism for the amplification of the scalar-induced GWs that is required to explain the PTA data can overproduce the PBHs over some ranges of masses. In this work, we assume a specific functional form for the primordial scalar power spectrum and examine the production of PBHs and the scalar-induced secondary GWs during the phase of reheating, which precedes the standard epoch of radiation domination. Specifically, we account for the uncertainties in the conditions for the formation of PBHs and ensure that the extent of PBHs produced remains within the observational bounds. We find that the scalar-induced SGWB generated during a phase of reheating with a steeper equation of state (than that of radiation) fit the NANOGrav 15-year data with a stronger Bayesian evidence than the astrophysical scenario involving GWs produced by merging supermassive binary black holes.
