description: While in the beginning of the environmental debate, conflicts over environmental and technological issues had primarily been understood in terms of "risk", over the past two decades the relevance of ignorance, or nonknowledge, was emphasized. Referring to this shift of attention to nonknowledge the article presents two main findings: first, that in debates on what is not known and how to appraise it different and partly conflicting epistemic cultures of nonknowledge can be discerned and, second, that drawing attention to nonknowledge in technology conflicts results in significant institutional effects and new constellations of actors in public debates. To illustrate and substantiate this political dynamics of nonknowledge we draw upon examples from the areas of agri-biotechnology and mobile phoning. In a first step, we develop in greater detail the concept of scientific cultures of nonknowledge and identify three such cultures involved in the social conflicts within the two areas. Subsequently, we analyze the specific dynamics of the politicisation of nonknowledge looking at the variety of actors involved and the pluralisation of perceptions and evaluations of what is not known. Then, we point out some of the institutional reactions to the political and cultural dynamics of scientific nonknowledge. We argue that the equal recognition of the diverse cultures of nonknowledge is a key prerequisite for socially legitimate and "robust" decision-making under conditions of politicised scientific nonknowledge. © The Author(s) 2010.

description: Spin noise (SN) spectroscopy measurements on delicate semiconductor spin systems, like single (In,Ga) As quantum dots, are currently not limited by optical shot noise but rather by the electronic noise of the detection system. We report on a realization of homodyne SN spectroscopy enabling shot-noise-limited SN measurements. The proof-of-principle measurements on impurities in an isotopically enriched rubidium atom vapor show that homodyne SN spectroscopy can be utilized even in the low-frequency spectrum, which facilitates advanced semiconductor spin research like higher order SN measurements on spin qubits.

description: Highly mismatched semiconductor alloys such as GaNAs and GaBiAs have several novel electronic properties, including a rapid reduction in energy gap with increasing x and also, for GaBiAs, a strong increase in spin orbit- splitting energy with increasing Bi composition. We review here the electronic structure of such alloys and their consequences for ideal lasers. We then describe the substantial progress made in the demonstration of actual GaInNAs telecomm lasers. These have characteristics comparable to conventional InP-based devices. This includes a strong Auger contribution to the threshold current. We show, however, that the large spin-orbit-splitting energy in GaBiAs and GaBiNAs could lead to the suppression of the dominant Auger recombination loss mechanism, finally opening the route to efficient temperature-stable telecomm and longer wavelength lasers with significantly reduced power consumption.

description: The absorption of heavily doped graphene in the terahertz (THz) and mid-infrared (MIR) spectral regions is considered taking into account both the elastic scattering due to finite-range disorder and the variations of concentration due to long-range disorder. Interplay between intra- and interband transitions is analyzed for the high-frequency regime of response, near the Pauli blocking threshold. The gate voltage and temperature dependencies of the absorption efficiency are calculated. It is demonstrated that for typical parameters, the smearing of the interband absorption edge is determined by a unscreened part of long-range disorder while the intraband absorption is determined by finite-range scattering. The latter yields the spectral dependencies which deviate from those following from the Drude formula. The obtained dependencies are in good agreement with recent experimental results. The comparison of the results of our calculations with the experimental data provides a possibility to extract the disorder characteristics.

description: Angle-resolved photoemission spectroscopy using tunable low energy photons allows us to study the quasi-particle (QP) dispersions of the inner and outer CuO2 planes (IP and OP) separately in the tri-layer cuprate Bi$_2$Sr$_2$Ca$_2$Cu$_3$O$_{10+δ}$ (Bi2223). The kink energy of the OP band is $\sim$ 70 meV, as observed in various high-$T_c$ cuprates, while that of the IP band is as large as 100 meV in the superconducting (SC) state. This large kink energy is attributed to the $\sim$ 35 meV buckling mode plus the large ($\sim$ 60 meV) SC gap of IP. The IP band also shows a weak kink feature at 70 meV in the SC state. The latter feature can be explained either by the 70 meV half-breathing mode or by the $\sim$ 35 meV buckling-phonon mode plus the $\sim$ 40 meV SC gap of OP if interlayer scattering of QP is involved.

description: This thesis examines the relationship between popular history and the misleading narratives about trans-Atlantic slavery, through an archival and ethnographic analysis of slavery history. Several generations of false textbook narratives and convenient whitewashing of historical accounts have given birth to a multitude of erroneous accounts of the Atlantic slave trade and slavery. Some narratives have been corrected in academic canon through rigorous archival investigation and ethnography; however, the widespread narrative that has had a pernicious life—not even an afterlife—in contemporary discourses is the notion that ‘Africans sold their own kinfolk into slavery.’ Neither textbook accounts nor academic scholarship have reached a consensus on the language or vocabulary necessary to address the African role in the Atlantic slave trade. Using archival investigation, semi-structured interviews, and online ethnography, I examine the relationship between academic scholarship, textbook history, and informal discourses on slavery and show that the narrative of wholesale African blame for the slave trade has negatively impacted Black intra-racial relations between Black diasporic groups in the United States. I also explain how textbook accounts gloss over essential facts about Atlantic slavery: (1) the chattelization of enslaved Africans of various ethnic and ethnoreligious differences; (2) U.S. and European implied allowances for slavery and slave trading long after abolition efforts were made; (3) the frequency of slave rebellions in the Americas; and (4) the logics of slaveholding societies in Brazil and the Caribbean that are deeply linked to the conditions of slavery in the United States.

description: For milling of aluminum alloys a roughing cutter is often used in the first step to achieve a high material removal rate. In order to obtain a high surface quality, the final contour is produced using a finishing cutter. By using a new and patented tool concept, both roughing and finishing operations can be carried out with this one tool. The special feature of this tool concept is based on the different geometric design of the individual cutting edges. A process-optimized design of the tool geometry of the prototype tool can be performed based on a preliminary calculation of the process forces and the dynamic behavior. The corresponding mathematical models have been developed for this purpose. On the basis of experimental investigations, the verification of the roughing and finishing capability of the tool concept was carried out. The results showed that the tool achieved comparable results in both cases to pure finishing and roughing cutters. It follows that the new tool concept can increase productivity by reducing the number of necessary end mills.

description: Surface enhanced Raman scattering (SERS) from biomolecules in living cells enables the sensitive, but also very selective, probing of their biochemical composition. This minireview discusses the developments of SERS probing in cells over the past years from the proof-of-principle to observe a biochemical status to the characterization of molecule–nanostructure and molecule–molecule interactions and cellular processes that involve a wide variety of biomolecules and cellular compartments. Progress in applying SERS as a bioanalytical tool in living cells, to gain a better understanding of cellular physiology and to harness the selectivity of SERS, has been achieved by a combination of live cell SERS with several different approaches. They range from organelle targeting, spectroscopy of relevant molecular models, and the optimization of plasmonic nanostructures to the application of machine learning and help us to unify the information from defined biomolecules and from the cell as an extremely complex system.
Nonparametric Bayesian Mixed-effect Model: a Sparse Gaussian Process Approach

description: Multi-task learning models using Gaussian processes (GP) have been developed and successfully applied in various applications. The main difficulty with this approach is the computational cost of inference using the union of examples from all tasks. Therefore sparse solutions, that avoid using the entire data directly and instead use a set of informative "representatives" are desirable. The paper investigates this problem for the grouped mixed-effect GP model where each individual response is given by a fixed-effect, taken from one of a set of unknown groups, plus a random individual effect function that captures variations among individuals. Such models have been widely used in previous work but no sparse solutions have been developed. The paper presents the first sparse solution for such problems, showing how the sparse approximation can be obtained by maximizing a variational lower bound on the marginal likelihood, generalizing ideas from single-task Gaussian processes to handle the mixed-effect model as well as grouping. Experiments using artificial and real data validate the approach showing that it can recover the performance of inference with the full sample, that it outperforms baseline methods, and that it outperforms state of the art sparse solutions for other multi-task GP formulations.

Desde há muito que assumem um papel central no processo de ensino e aprendizagem, adaptando-se às mudanças que ocorrem tanto na sociedade em geral, como no sistema de ensino em particular. São recursos que, por um lado, facilitam a vida do professor porque pretendem dar conta dos conteúdos das disciplinas e, por outro, permitem aos alunos aceder ao conhecimento e realizar atividades relacionadas com a construção de saberes, nas mais variadas áreas. O presente trabalho foca-se no papel dos manuais de Estudo do Meio no desenvolvimento de competências de leitura. Para tal, analisam- se os seis manuais escolares de Estudo do Meio do 4.º ano adotáveis atualmente em Portugal. Caraterizam-se os textos e as atividades do ponto de vista da compreensão na leitura e do acesso ao conhecimento, com recurso a uma grelha de análise, teoricamente sustentada, criada especificamen e para este estudo. Os resultados mostram que, no geral, os textos pertencem todos ao mesmo género textual e apresentam estruturas semelhantes. As atividades são apresentadas, sobretudo, após a leitura dos textos e são pouco expressivas as atividades de preparação da leitura, como o trabalho de vocabulário, a realização de previsões sobre o texto ou a ativação de conhecimentos prévios. Relativamente às questões, dominam as de compreensão literal e a construção de esquemas ou resumos é pouco valorizada.

 – bar by bar – tempi in the first movements of three of Ludwig van Beethoven’s piano sonatas (Appassionata Sonata, Sonata op. 2 Nr. 3, Hammerklavier Sonata) in interpretations from the 1920s through the 2000s. In so doing we examined a series of factors: Have the tempo and shaping of tempo (›Tempogestaltung‹) changed over time? Are there national or culture-specific traditions? Can inter-subjective tempo decisions be identified? How had the shaping of tempi by an individual artist developed over the years and decades? What is the relationship between interpretational practice and the recommendations in the editions prepared by celebrated interpreters?

description: Abstract: The portraits of the noble robbers and images of their bravery have a double role: on the one hand, they break the linearity of the discourse and intensify the suspense, and on the other hand, they give concreteness to the carefully constructed fleeting image of the literary text. The very practice of publishing works of fiction accompanied by graphic representations of significant scenes underpins the rise of the novel. Western literature of the eighteenth and nineteenth centuries took full advantage of the commercial success of graphic inserts, and Romanian literature adopted this technique to streamline the circulation of the novel's message. In addition to its specific role as an entertaining element, we cannot deny the fundamental role of illustration as a semiotic instrument. In the hajduk novel, the illustration mediates the crystallization of the noble outlaw image because it compresses essential biographical information and offers a translation of his personality. The graphic elements direct the novel's content to a specific audience with an appetite for particular ideological messages. The portraits of the main characters, captured in edifying poses for the development of their identity as symbols of social resistance, are likely to influence the entire literary system configured by the subgenre, imposing their associative and analogical force.
Keywords: noble outlaw, portrait, ideology, representation, social resistance.

description: We study functional activity in the human brain using functional Magnetic Resonance Imaging and recently developed tools from network science. The data arise from the performance of a simple behavioural motor learning task. Unsupervised clustering of subjects with respect to similarity of network activity measured over three days of practice produces significant evidence of `learning', in the sense that subjects typically move between clusters (of subjects whose dynamics are similar) as time progresses. However, the high dimensionality and time-dependent nature of the data makes it difficult to explain which brain regions are driving this distinction. Using network centrality measures that respect the arrow of time, we express the data in an extremely compact form that characterizes the aggregate activity of each brain region in each experiment using a single coefficient, while reproducing information about learning that was discovered using the full data set. This compact summary allows key brain regions contributing to centrality to be visualized and interpreted. We thereby provide a proof of principle for the use of recently proposed dynamic centrality measures on temporal network data in neuroscience.

description: Recent advances in sleep neurobiology have allowed development of physiologically based mathematical models of sleep regulation that account for the neuronal dynamics responsible for the regulation of sleep-wake cycles and allow detailed examination of the underlying mechanisms. Neuronal systems in general, and those involved in sleep regulation in particular, are noisy and heterogeneous by their nature. It has been shown in various systems that certain levels of noise and diversity can significantly improve signal encoding. However, these phenomena, especially the effects of diversity, are rarely considered in the models of sleep regulation. The present paper is focused on a neuron-based physiologically motivated model of sleep-wake cycles that proposes a novel mechanism of the homeostatic regulation of sleep based on the dynamics of a wake-promoting neuropeptide orexin. Here this model is generalized by the introduction of intrinsic diversity and noise in the orexin-producing neurons in order to study the effect of their presence on the sleep-wake cycle. A quantitative measure of the quality of a sleep-wake cycle is introduced and used to systematically study the generalized model for different levels of noise and diversity. The model is shown to exhibit a clear diversity-induced resonance: that is, the best wake-sleep cycle turns out to correspond to an intermediate level of diversity at the synapses of the orexin-producing neurons. On the other hand only a mild evidence of stochastic resonance is found when the level of noise is varied. These results show that disorder, especially in the form of quenched diversity, can be a key-element for an efficient or optimal functioning of the homeostatic regulation of the sleep-wake cycle. Furthermore, this study provides an example of constructive role of diversity in a neuronal system that can be extended beyond the system studied here.

description: Excerpts from the report: An experimental air system called the "monoflow system," in which the airstreams are connected in series, is under development at the USDA Southwestern Cotton Ginning Research Laboratory at Mesilla Park, N. Mex. This system provides a method of controlling the moisture content of the cotton through the entire ginning process to maintain maximum quality, and also aids in air pollution control by reducing the number of final exhaust airstreams. In the laboratory setup, the number of airstreams has been reduced to two—one to handle the seed cotton and one to handle the lint. The experimental studies for the report had three objectives: (1) To evaluate the effects of the monoflow ginning air system and a conventional ginning air system on ginning operations, cotton quality, and spinning performance; (2) to evaluate the effects on these aspects of cotton processing of the fiber-moisture control provided by the monoflow system during ginning; and (3) to evaluate the effects of the use of card crusher rolls on the spinning performance of cotton ginned with the monoflow ginning air system and with a conventional ginning air system.

description: The study of Type Ia supernovae (SNIa) has lead to greatly improved insights into many fields in astrophysics, however a theoretical explanation of the origin of these events is still lacking. We investigate the potential contribution to the SNIa rate from the population of merging double carbon-oxygen white dwarfs. We aim to develope a model that fits the observed SNIa progenitors as well as the observed close double white dwarf population. We differentiate between two scenarios for the common envelope (CE) evolution; the alpha-formalism based on the energy equation and the gamma-formalism that is based on the angular momentum equation. In one model we apply the alpha-formalism always. In the second model the gamma-formalism is applied, unless the binary contains a compact object or the CE is triggered by a tidal instability for which the alpha-formalism is used. The binary population synthesis code SeBa was used to evolve binary systems from the zero-age main sequence to the formation of double white dwarfs and subsequent mergers. SeBa has been thoroughly updated since the last publication of the content of the code. The limited sample of observed double white dwarfs is better represented by the simulated population using the gamma-formalism than the alpha-formalism. For both CE formalisms, we find that although the morphology of the simulated delay time distribution matches that of the observations within the errors, the normalisation and time-integrated rate per stellar mass are a factor 7-12 lower than observed. Furthermore, the characteristics of the simulated populations of merging double carbon-oxygen white dwarfs are discussed and put in the context of alternative SNIa models for merging double white dwarfs.

Publishing reproducible results supported by FAIR data
Creators: name: Nieva de la Hidalga, Abraham
Publisher: name: Zenodo
Year: 2023

description: We discuss two techniques for processing and analysing data that at the same time generate the required metadata to create FAIR digital objects. These objects can then be published as supporting information for the results obtained. This approach requires minimum intervention from the researcher performing the processing and analysis tasks. Consequently, these methods are ideal for improving the practices of publishing data, facilitate reproducibility of results, and support greater reuse of published data.
Both techniques produce the metadata required for reproducing the results, including data used, parameters set at each stage, sequence of operations and mapping between inputs and outputs. The use of these type of tools reduces the work for documenting supporting data, enables comparison of results when varying parameters, and supports exploratory testing of different parameter combinations.

description: Aims. We present here a new theoretical approach to population synthesis. The aim is to predict colour magnitude diagrams (CMDs) for huge numbers of stars. With this method we generate synthetic CMDs for N-body simulations of galaxies. Sophisticated hydrodynamic N-body models of galaxies require equal quality simulations of the photometric properties of their stellar content. The only prerequisite for the method to work is very little information on the star formation and chemical enrichment histories, i.e. the age and metallicity of all star-particles as a function of time. The method takes into account the gap between the mass of real stars and that of the star-particles in N-body simulations, which best correspond to the mass of star clusters with different age and metallicity, i.e. a manifold of single stellar sopulations (SSP). Methods. The theory extends the concept of SSP to include the phase-space (position and velocity) of each star. Furthermore, it accelerates the building up of simulated CMD by using a database of theoretical SSPs that extends to all ages and metallicities of interest. Finally, it uses the concept of distribution functions to build up the CMD. The technique is independent of the mass resolution and the way the N-body simulation has been calculated. This allows us to generate CMDs for simulated stellar systems of any kind: from open clusters to globular clusters, dwarf galaxies, or spiral and elliptical galaxies. Results. The new theory is applied to an N-body simulation of a disc galaxy to test its performance and highlight its flexibility.

Adiabatic piston in a temperature gradient

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The steady states of two gases of hard spheres or disks separated by an adiabatic piston in presence of a temperature gradient are discussed. The temperature field is generated by two thermal walls at different temperatures, each of them in contact with one of the gases. The presence of the piston strongly affects the hydrodynamic fields, inducing a jump in its vicinity. A simple kinetic theory model is formulated. Its predictions are shown to be in good agreement with molecular dynamics simulation results. The applicability of the minimum entropy production principle is analyzed, and it is found that it only provides an accurate description of the system in the limit of a small temperature gradient.

We also prove the optimality of the constants. The method is flexible and yields a sharp expression for the remainder terms in these inequalities.

A differential approach for bounding the index of graphs under perturbations

description: This paper presents bounds for the variation of the spectral radius $λ(G)$ of a graph $G$ after some perturbations or local vertex/edge modifications of $G$. The perturbations considered here are the connection of a new vertex with, say, $g$ vertices of $G$, the addition of a pendant edge (the previous case with $g=1$) and the addition of an edge. The method proposed here is based on continuous perturbations and the study of their differential inequalities associated. Within rather economical information (namely, the degrees of the vertices involved in the perturbation), the best possible inequalities are obtained. In addition, the cases when equalities are attained are characterized. The asymptotic behavior of the bounds obtained is also discussed. For instance, if $G$ is a connected graph and $G_u$ denotes the graph obtained from $G$ by adding a pendant edge at vertex $u$ with degree $δ_u$, then, $$ λ(G_u)\le λ(G)+\frac{δ_u}{λ^3(G)}+\textrm{o}(\frac{1}{λ^3(G)}). $$

description: String theory on NS-NS AdS_3 x S^3 admits an exactly marginal deformation which breaks the SL(2,R)_R x SL(2,R)_L isometry of AdS_3 down to SL(2,R)_R x U(1)_L. The holographic dual is an exotic and only partially understood type of two-dimensional CFT with a reduced unbroken global conformal symmetry group. In this paper we study the deformed theory on the string worldsheet. It is found to be related by a spectral flow which is nonlocal in spacetime to the undeformed worldsheet theory. An exact formula for the spectrum of massive strings is presented.

description: The signal modelling framework JimenaE simulates dynamically Boolean networks. In contrast to SQUAD, there is systematic and not just heuristic calculation of all system states. These specific features are not present in CellNetAnalyzer and BoolNet. JimenaE is an expert extension of Jimena, with new optimized code, network conversion into different formats, rapid convergence both for system state calculation as well as for all three network centralities. It allows higher accuracy in determining network states and allows to dissect networks and identification of network control type and amount for each protein with high accuracy. Biological examples demonstrate this: (i) High plasticity of mesenchymal stromal cells for differentiation into chondrocytes, osteoblasts and adipocytes and differentiation-specific network control focusses on wnt-, TGF-beta and PPAR-gamma signaling. JimenaE allows to study individual proteins, removal or adding interactions (or autocrine loops) and accurately quantifies effects as well as number of system states. (ii) Dynamical modelling of cell–cell interactions of plant Arapidopsis thaliana against Pseudomonas syringae DC3000: We analyze for the first time the pathogen perspective and its interaction with the host. We next provide a detailed analysis on how plant hormonal regulation stimulates specific proteins and who and which protein has which type and amount of network control including a detailed heatmap of the A.thaliana response distinguishing between two states of the immune response. (iii) In an immune response network of dendritic cells confronted with Aspergillus fumigatus, JimenaE calculates now accurately the specific values for centralities and protein-specific network control including chemokine and pattern recognition receptors.

description: We theoretically describe the dynamics of swimmer populations confined in thin liquid films. We first demonstrate that hydrodynamic interactions between confined swimmers only depend on their shape and are independent of their specific swimming mechanism. We also show that due to friction with the walls, confined swimmers do not reorient due to flow gradients but the flow field itself. We then quantify the consequences of these microscopic interaction rules on the large-scale hydrodynamics of isotropic populations. We investigate in details their stability and the resulting phase behavior, highlighting the differences with conventional active, three-dimensional suspensions. Two classes of polar swimmers are distinguished depending on their geometrical polarity. The first class gives rise to coherent directed motion at all scales whereas for the second class we predict the spontaneous formation of coherent clusters (swarms).
