Humidophila contenta

description: Humidophila contenta (Grunow) R.L. Lowe et al. (Figs 18–38)
 Morphological observations:—Smaller specimens elliptical with parallel margins, larger specimens linear, usually with concave margins and broadly rounded, never (sub-)capitate ends.Valve dimensions (n=25): length 6.1 – 11.6 μm, width 2.1–2.9 μm. Axial area narrow, linear. Central fascia clearly present, extending from the central nodule to the valve margins. Raphe filiform, straight with distinct T-shaped central and terminal endings. Transapical striae parallel, interrupted centrally, fine, difficult to resolve in LM, 34 – 49 in 10 μm. Mantle areolae rounded to elongated, continuing around the apices without an interruption. Girdle composed of three copulae, perforated by a series of transapically elongated slits.
 Ecology and associated diatom flora:—Based on valve morphology, Humidophila contenta is one of the few cosmopolitan species of this genus. It has been reported worldwide in soils, subaerial habitats, in small bodies of oligotrophic acidic water and in biotopes with greatly reduced light intensity (Werum & Lange-Bertalot 2004, Poulíčková & Hašler 2007). On Ile Amsterdam and Ile Saint Paul H. contenta has been found living on moss species of the genus Anthoceros L., Brachythecium Schimp. and Sphagnum L. showing a specific moisture value ranging from F-V to F-VII, and in soils, usually accompanied by Humidophila vidalii, H. amsterdamensis sp.nov., Eunotia muscicola Krasske (1939: 366), Pinnularia borealis Ehrenberg (1843b: 420) s.l., Pinnularia perminor Kulikovskiy, Lange-Bertalot & Metzeltin (2010: 359), Luticola beyensii and Tryblionella debilis Arnott ex O’Meara (1873: 310).

description: We analytically study membrane mediated interactions between inclusions embedded in a tubular membrane. We model inclusions as constraints coupled to the curvature tensor of the membrane tube. First, as special test cases, we analyze the interaction between ring and rod shaped inclusions. Using Monte Carlo simulations, we further show how point-like inclusions interact to form linear aggregates. Our results reveal that depending on the hard-core radius of the inclusions, they arrange into either lines or rings to globally minimize the curvature energy of the membrane.

Feasibility of the concept Mobility as a Service and its ability to support e-mobility in Germany
Creators: name: Schädel, Marius
Publisher: name: Technische Universität Dortmund
Year: 2018
Subjects: subject: 620

description: The mobility sector in Germany is currently exposed to great challenges and chances. On the one hand trends like urbanization and a high degree of individual traffic lead to difficulties in reaching an efficient and sustainable mobility system which correspondents with national and international climate targets. On the other hand the current personal mobility system struggles to exploit the opportunities that are given by the trend of digitalization. Against this background, the examination of an alternative mobility system called Mobility as a Service is reasonable. Core elements of Mobility as a Service are multimodality, mobility services in a one shop principle and the minimization of individual traffic. Nevertheless the implementation of Mobility as a Service requires specific conditions which are basically defined by technology, politics, economy and infrastructure. Due to its core elements, Mobility as a Service leads to a highly efficient and modern transport system. At the same time Mobility as a Service can be the base for further developments in the field of e-mobility in Germany. The thesis finds out that there is a chance to implement the concept of Mobility as a Service in Germany and that provides good conditions to boost the use of electric vehicles.
title: The Gifford Report Revisited Racism in Employment: A Case Study of Liverpool
Creators: name: Elmi, Amina
Publisher: name: University of Liverpool Repository
Year: 2020

description: Race relations’ legislation since 1965 onwards in the UK has attempted to address the challenges of racial inequality when it comes to employment. Though there have been significant improvements, there remain some challenges in specific locations. One such location is Liverpool. This research is based on the seminal study, the Gifford Report (1989), which provided evidences to support the argument that Liverpool performed worse than the rest of the country with respect to indicators of racial equality in the labour market (Brown, 1979, Lord Scarman, 1981, Ben-Tovin, 1983). The current research focuses on Liverpool, which is considered to be an anomaly in terms of racialised relationships and the Black experience across England (Small 1991, Murphy 1995 Christian 1998). This research attempts to determine if there has been an improvement in racial equality with respect to employment. The study aims to understand the limitations and possibilities associated with Black social mobility within the labour market, and to identify key challenges to upward mobility. The study replicates certain elements of the methodology of the 1989 Gifford Report, using semi-structured interviews, oral testimonies, written requests, head-count analysis and secondary statistical data. The findings of the qualitative and quantitative methods present overwhelming evidence that racism remains a key challenge, which can impact access to employment. The findings show the presence of systemic and institutional racism: participants feel disadvantaged because of ethnicity, with negative perceptions and stereotyping limiting opportunities for employment. The research concludes with the argument that some challenges identified in the Gifford Report (1989) have been met by specific policies proposed by local and national governments. However, there remain systemic challenges that need to be addressed. The research reflects on critical race theory and concludes that the existing dominance and perceived hegemony of racial inequality need to be revisited.
Implications on the use of sci-hub in academic library services: brief considerations regarding its constraints to academic libraries

description: Knowledge is built on prior knowledge, so access to information is essential. The development of digital
 technologies introduced new channels of communication and information distribution, having unleashed new forms
 of access to information, and making it possible, at the same time, to open up research. Despite the advancement
 and awareness of the adoption of open access and open science principles, there are still some barriers around the
 current system of scholarly communication that have triggered alternative forms of access to the literature, not
 always legal and legitimate, giving rise to illegal access to scholarly information, also known in the literature as
 guerrilla open access or black open access. Illegal access to information is mainly related to non-compliance with
 the copyright laws of scholarly works when making content available on digital platforms. The use of illegal
 platforms, such as sci-hub, which gathers a massive collection of scholarly resources, globally, quickly, and free of
 charge, but that violates copyright, is a challenge to some of the stakeholders involved in the scholarly
 communication system. Academic libraries, which since their beginnings, have had as their primary objective to
 provide access and availability to information of excellence, may now face serious consequences related to the use
 of this platform. Taking this into consideration, does the use of sci-hub, by the research community, affects the
 services of an academic library? Since academic libraries are considered a system, whose parts establish bilateral
 relations with each other, if one of the parts is compromised it implies that the others are harmed. The main focus of
 this research is to study the influence that the use of an illegal platform for the retrieval of scholarly journal articles
 - sci-hub - has on academic libraries and to understand the long-term implications that the use of this platform has
 on academic library services. As specific goals, it is proposed to understand how the use of sci-hub impacts the
 services of academic libraries; to perceive the interconnection between the services provided by libraries and the
 vulnerability that these present when affected by an external factor. The present work is characterized as an
 exploratory study of a qualitative nature, in which it is intended to apply for a literature review on illegal access,
 sci-hub, and academic library services. It is hoped to raise awareness around the constraints related to the use of
 sci-hub and the implications it has on academic libraries services in the long term.

description: Plants live in biogeochemically diverse soils that harbor extraordinarily diverse microbiota. Plant organs associate intimately with a subset of these microbes; this community’s structure can be altered by soil nutrient content. Plant-associated microbes can compete with the plant and with each other for nutrients; they can also provide traits that increase plant productivity. It is unknown how the plant immune system coordinates microbial recognition with nutritional cues during microbiome assembly. We establish that a genetic network controlling phosphate stress response influences root microbiome community structure, even under non-stress phosphate conditions. We define a molecular mechanism regulating coordination between nutrition and defense in the presence of a synthetic bacterial community. We demonstrate that the master transcriptional regulators of phosphate stress response in Arabidopsis also directly repress defense, consistent with plant prioritization of nutritional stress over defense. Our work will impact efforts to define and deploy useful microbes to enhance plant performance.

description: Covering a graph or a lattice with non-overlapping dimers is a problem that has received considerable interest in areas such as discrete mathematics, statistical physics, chemistry and materials science. Yet, the problem of percolation on dimer-covered lattices has received little attention. In particular, percolation on lattices that are fully covered by non-overlapping dimers has not evidently been considered. Here, we propose a novel procedure for generating random dimer coverings of a given lattice. We then compute the bond percolation threshold on random and ordered coverings of the square and the triangular lattice, on the remaining bonds connecting the dimers. We obtain $p_c=0.367713(2)$ and $p_c=0.235340(1)$ for random coverings of the square and the triangular lattice, respectively. We observe that the percolation frustration induced as a result of dimer covering is larger in the low-coordination-number square lattice. There is also no relationship between the existence of long-range order in a covering of the square lattice, and its percolation threshold. In particular, an ordered covering of the square lattice, denoted by shifted covering in this work, has an unusually low percolation threshold, and is topologically identical to the triangular lattice. This is in contrast to the other ordered dimer coverings considered in this work, which have higher percolation thresholds than the random covering. In the case of the triangular lattice, the percolation thresholds of the ordered and random coverings are very close, suggesting the lack of sensitivity of the percolation threshold to microscopic details of the covering in highly-coordinated networks.

 Morphological observations:—Larger specimens linear with strongly undulating margins and broadly rounded subcapitate apices, smaller specimens linear with more parallel margins, usually lacking the typical double undulation and the gibbous apices. Valve dimensions (n=20): length 11.2 – 14.9 μm, width 2 – 3.2 μm. Width of the apices never extend beyond the valve undulations. Axial area well-defined, linear. Central area widened, generally bordered by 3 striae. Raphe straight filiform with only slightly marked endings. Distal raphe endings terminating near the last striae. Striae slightly radiate in the middle, becoming more convergent towards the apices, 32 – 34 in 10 μm. Mantle areolae elongated, continuing around the apices lacking an interruption at the apices.

 Ecology and associated diatom flora:— Humidophila crozetikerguelensis is originally described from Kerguelen, where it is common in semi-wet soils with higher specific conductance values and higher phosphorous and chloride concentrations (Le Cohu & Van de Vijver 2002). On Ile Amsterdam, the species was found in high abundance on both wet and terrestrial mosses with a wide F-value range of II–VII, and occasionally on wet mosses and soils on Ile Saint Paul. The associated diatom community is composed of other Humidophila species (Humidophila amsterdamensis, H. rouhaniana, H. vidalii, H. contenta), Eunotia paludosa, Achnanthes coarctata (Brébisson ex W. Smith 1855: 8) Grunow in Cleve & Grunow (1880: 20), Frustulia lebouvieri and Eunotia muscicola.

description: Observations of tropical convection from precipitation radar and the concurring large-scale atmospheric state at two locations (Darwin and Kwajalein) are used to establish effective stochastic models to parameterise subgrid-scale tropical convective activity. Two approaches are presented which rely on the assumption that tropical convection induces a stationary equilibrium distribution. In the first approach we parameterise convection variables such as convective area fraction as an instantaneous random realisation conditioned on the large-scale vertical velocities according to a probability density function estimated from the observations. In the second approach convection variables are generated in a Markov process conditioned on the large-scale vertical velocity, allowing for non-trivial temporal correlations. Despite the different prevalent atmospheric and oceanic regimes at the two locations, with Kwajalein being exposed to a purely oceanic weather regime and Darwin exhibiting land-sea interaction, we establish that the empirical measure for the convective variables conditioned on large-scale mid-level vertical velocities for the two locations are close. This allows us to train the stochastic models at one location and then generate time series of convective activity at the other location. The proposed stochastic subgrid-scale models adequately reproduce the statistics of the observed convective variables and we discuss how they may be used in future scale-independent mass-flux convection parameterisations.

description: Hundreds of thousands of human genomes are now being sequenced to characterize genetic variation and use this information to augment association mapping studies of complex disorders and other phenotypic traits. Genetic variation is identified mainly by mapping short reads to the reference genome or by performing local assembly. However, these approaches are biased against discovery of structural variants and variation in the more complex parts of the genome. Hence, large-scale de novo assembly is needed. Here we show that it is possible to construct excellent de novo assemblies from high-coverage sequencing with mate-pair libraries extending up to 20 kilobases. We report de novo assemblies of 150 individuals (50 trios) from the GenomeDenmark project. The quality of these assemblies is similar to those obtained using the more expensive long-read technology. We use the assemblies to identify a rich set of structural variants including many novel insertions and demonstrate how this variant catalogue enables further deciphering of known association mapping signals. We leverage the assemblies to provide 100 completely resolved major histocompatibility complex haplotypes and to resolve major parts of the Y chromosome. Our study provides a regional reference genome that we expect will improve the power of future association mapping studies and hence pave the way for precision medicine initiatives, which now are being launched in many countries including Denmark.

description: Prior knowledge of the social aspects of prospective destinations can be very influential in making travel destination decisions, especially in instances where social concerns do exist about specific destinations. In this paper, we describe the implementation of an ontology-enabled Hybrid Destination Recommender System (HDRS) that leverages an ontological description of five specific social attributes of major Nigerian cities, and hybrid architecture of content-based and case-based filtering techniques to generate personalised top-n destination recommendations. An empirical usability test was conducted on the system, which revealed that the dependability of recommendations from Destination Recommender Systems (DRS) could be improved if the semantic representation of social attributes information of destinations is made a factor in the destination recommendation process.

The paper addresses this question and demonstrates that the fullerene shell layer in such a bucky-corn structure can be stable. Theoretical study of structure, stability and electronic properties of the following bucky-corn hybrids is reported: C60 and C70 molecules on an individual SWCNT, C60 dimers on an individual SWCNT as well C60 molecules on SWNT bundles. The geometry and total energies of the bucky-corns were calculated by the molecular dynamics method while the density functional theory method was used to simulate the electronic band structures.

description: Two-photon calcium imaging provides an optical readout of neuronal activity in populations of neurons with subcellular resolution. However, conventional two-photon imaging systems are limited in their field of view to ~1 mm2, precluding the visualization of multiple cortical areas simultaneously. Here, we demonstrate a two-photon microscope with an expanded field of view (>9.5 mm2) for rapidly reconfigurable simultaneous scanning of widely separated populations of neurons. We custom designed and assembled an optimized scan engine, objective, and two independently positionable, temporally multiplexed excitation pathways. We used this new microscope to measure activity correlations between two cortical visual areas in mice during visual processing.

description: Efforts to develop gene therapies for hearing loss have been hampered by the lack of safe, efficient, and clinically relevant delivery modalities1, 2. Here we demonstrate the safety and efficiency of Anc80L65, a rationally designed synthetic vector3, for transgene delivery to the mouse cochlea. Cochlear explants incubated with Anc80L65 encoding eGFP demonstrated high level transduction of inner and outer hair cells (60–100%). Injection of Anc80L65 through the round window membrane resulted in highly efficient transduction of inner and outer hair cells, a substantial improvement over conventional adeno-associated virus (AAV) vectors. Anc80L65 round window injection was well tolerated, as indicated by sensory cell function, hearing and vestibular function, and immunologic parameters. The ability of Anc80L65 to target outer hair cells at high rates, a requirement for restoration of complex auditory function, may enable future gene therapies for hearing and balance disorders.

 Morphological observations:—Frustules are rectangular in girdle view, usually forming long, bandlike colonies, connected by linking spines. Valves are linear-elliptical with bluntly rounded, rarely subcapitate apices. Valve dimensions (n=25): length 8–11.5 μm, width 1.9 – 3.2 μm. Two contrasting valves morphologies are observed. Most valves lacking a raphe system but are showing well-developed marginal spines. Occasionally valves with a normally developed raphe system lacking marginal spines were observed. Striae are not discernible in LM, 34 – 42 in 10 μm, composed (SEM) of one large, transapically elongated areola.
 Ecology and associated diatom flora: — Humidophila gallica is a cosmopolitan species, common in terrestrial biotopes such as bryophyte vegetations, wet to semi-dry rock faces, soils and in caves (Falasco et al. 2014, 2015, Lowe et al. 2017). On Ile Amsterdam, this species was found in high abundance in lava tubes, accompanied by other Humidophila species (mainly H. vidalii and H. contenta), Rhopalodia rupestris (W. Smith 1853: 14) Krammer in Lange-Bertalot & Krammer (1987: 86) and Orthoseira roeseana (Rabenhorst 1848 –1860: 383) O’Meara (1875: 255).

description: We apply the Lefschetz thimble formulation of field theories to a couple of different problems. We first address the solution of a complex 0-dimensional phi^4 theory. Although very simple, this toy-model makes us appreciate a few key issues of the method. In particular, we will solve the model by a correct accounting of all the thimbles giving a contribution to the partition function and we will discuss a number of algorithmic solutions to simulate this (simple) model. We will then move to a chiral random matrix (CRM) theory. This is a somehow more realistic setting, giving us once again the chance to tackle the same couple of fundamental questions: how many thimbles contribute to the solution? how can we make sure that we correctly sample configurations on the thimble? Since the exact result is known for the observable we study (a condensate), we can verify that, in the region of parameters we studied, only one thimble contributes and that the algorithmic solution that we set up works well, despite its very crude nature. The deviation of results from phase quenched results highlights that in a certain region of parameter space there is a quite important sign problem. In view of this, the success of our thimble approach is quite a significant one.

description: Because there are currently no biological treatments for deafness, we sought to advance gene therapy approaches to treat genetic deafness. We reasoned that gene delivery systems that target auditory and vestibular sensory cells with high efficiency would be required to restore complex auditory and balance function. We focused on Usher Syndrome, a devastating genetic disorder that causes blindness, balance disorders and profound deafness, and used a knock-in mouse model, Ush1c c.216G>A, which carries a cryptic splice site mutation found in French-Acadian patients with Usher Syndrome type IC (USH1C). Following delivery of wild-type Ush1c into the inner ears of neonatal Ush1c c.216G>A mice, we find recovery of gene and protein expression, restoration of sensory cell function, rescue of complex auditory function and recovery of hearing and balance behavior to near wild-type levels. The data represent unprecedented recovery of inner ear function and suggest that biological therapies to treat deafness may be suitable for translation to humans with genetic inner ear disorders.

description: The Ndc80 complex (Ndc80, Nuf2, Spc24, Spc25) is a highly conserved kinetochore protein essential for end-on anchorage to spindle microtubule plus-ends and for force generation coupled to plus-end polymerization and depolymerization. Spc24/Spc25 at one end of the Ndc80 complex binds the kinetochore. The N-terminal tail and CH domains of Ndc80 bind microtubules, and an internal domain binds microtubule-associated proteins (MAPs) such as the Dam1 complex. To determine how the microtubule and MAP binding domains of Ndc80 contribute to force production at the kinetochore in budding yeast, we have inserted a FRET tension sensor into the Ndc80 protein about halfway between its microtubule binding and internal loop domains. The data support a mechanical model of force generation at metaphase where the position of the kinetochore relative to the microtubule plus-end reflects the relative strengths of microtubule depolymerization, centromere stretch and microtubule binding interactions with Ndc80 and Dam1 complexes.

description: We analyze the impact of strong correlations on the surface states of a three-dimensional topological Kondo insulator. An important observation is that correlations are strongly increased at the surface, which leads to an energetical confinement of the surface $f$-electrons into a narrow window around the Fermi energy at low enough temperature. This correlation effect in combination with the nontrivial topology has two remarkable consequences: (i) coexistence of light and heavy surface states at low temperatures. While heavy surface states are formed directly in the surface layer, light surface states are formed in the next-nearest surface layer. Furthermore, (ii) with increasing the temperature, the heavy surface states become incoherent and only light surface states can be observed. The coexistence of light and heavy surface states is thereby a remarkable characteristic of the combination of strong correlations and nontrivial topology. We believe that these results are applicable to the candidate topological Kondo insulator SmB6.

description: Pluripotent embryonic stem cells (ESCs) self-renew or differentiate into all tissues of the developing embryo and cell-specification factors are necessary to balance gene expression. Here we delineate the function of the PHD-finger protein 5a (Phf5a) in ESC self-renewal and ascribe its role in regulating pluripotency, cellular reprogramming, and myoblast specification. We demonstrate that Phf5a is essential for maintaining pluripotency, since depleted ESCs exhibit hallmarks of differentiation. Mechanistically, we attribute Phf5a function to the stabilization of the Paf1 transcriptional complex and control of RNA polymerase II elongation on pluripotency loci. Apart from an ESC-specific factor, we demonstrate that Phf5a controls differentiation of adult myoblasts. Our findings suggest a potent mode of regulation by the Phf5a in stem cells, which directs their transcriptional program ultimately regulating maintenance of pluripotency and cellular reprogramming.
title: Evaluation of the Magnetic Field Signature as a Potential Parameter for Power Semiconductor Degradation Detection

description: This work investigates the viability of using the spatial magnetic flux density distribution caused by a semiconductors load current as a parameter to detect degradation of its bond wires and solder joinings. Utilizing a 3D FEM model of a singular IGBT on DCB, simulations of the B-field distribution for samples with intact and partially interrupted solder layer are conducted. The simulation results show that the partial interruption affects the B-field above the bond wires due to a redistribution of the load current. This is confirmed by measurements of the magnetic flux density distribution conducted on samples with identical structure to the model. Utilizing power cycling tests, 40 additional IGBT samples were artificially aged. The observed degradation mechanisms are bond wire lift-off with varying severity as well as strong vertical solder crack propagation emanating from the chips centre area. Measurements conducted for all aged samples show that the observed type of solder crack pattern has no significant influence on the B-field distribution above the semiconductor. Therefore a detectability using the proposed method can be ruled out. Regarding bond wire lift-offs it is shown that, besides the detection, a localisation as well as an identification is possible. Finally, a method for the determination of the bond wire current distribution is investigated. For this, an analytical model of the spatial magnetic flux density distribution, caused by the current flow in multiple bond wire loops, is derived. Utilizing said model in combination with discrete B-Field measurements, an optimisation approach is presented for the identification and localisation of bond wire lift-offs based on deviations in the estimated current distribution. A first viability analysis shows that the approach is capable to identify and localize bond wire lift-offs within the artificially aged samples.

description: Protein kinase signaling along the kinetochore-centromere axis is crucial to assure mitotic fidelity, yet its spatial coordination is obscure. Here, we examined how pools of human Polo-like kinase 1 (Plk1) within this axis control signaling events to elicit mitotic functions. To do this, we restricted active Plk1 to discrete subcompartments within the kinetochore-centromere axis using chemical genetics and decoded functional and phosphoproteomic signatures of each. We observe distinct phosphoproteomic and functional roles, suggesting that Plk1 exists and functions in discrete pools along this axis. Deep within the centromere, Plk1 operates to assure proper chromosome alignment and segregation. Thus, Plk1 at the kinetochore is a conglomerate of an observable bulk pool coupled with additional functional pools below the threshold of microscopic detection/resolution. Although complex, this multiplicity of locales provides an opportunity to decouple functional and phosphoproteomic signatures for a comprehensive understanding of Plk1’s kinetochore functions.
Measuring the impact of an instructional laboratory on the learning of introductory physics

description: We have analyzed the impact of taking an associated lab course on the scores on final exam questions in two large introductory physics courses. Approximately a third of the students who completed each course also took an accompanying instructional lab course. The lab courses were fairly conventional, although they focused on supporting the mastery of a subset of the introductory physics topics covered in the associated course. Performance between students who did and did not take the lab course was compared using final exam questions from the associated courses that related to concepts from the lab courses. The population of students who took the lab in each case was somewhat different from those who did not enroll in the lab course in terms of background and major. Those differences were taken into account by normalizing their performance on the lab-related questions with scores on the exam questions that did not involve material covered in the lab. When normalized in this way, the average score on lab-related questions of the students who took the lab, in both courses, was within 1% of the score of students who did not, with an uncertainty of 2%. This result raises questions as to the effectiveness of labs at supporting mastery of physics content.

The Role Of Measurement Devices In Defining The Field Of Social Impact Investment

description: This thesis addresses the recent calls for research in Social Impact Investing (SII), a new global approach to solve society’s most difficult problems through philanthropy, business innovation and finance. Questions revolving around the definition of terms such as Social Finance, as well as related concepts such as Social Enterprise, Social Impact and Social Impact Measurement, have engaged academics (and practitioners) for decades, but there is no consensus about what they mean. This thesis aims to shed light on this debate. Influenced by Bourdieu’s Field Theory, the approach used investigates the field of SII and its struggle for legitimacy, positions and industry standards using the concept of Market Devices from Social Studies of Finance to explore these dynamics. This investigation draws on 24 interviews with SII managers, 330 industry reports and 21 events that the researcher took part in. The contributions of this research to the field are the following. First, the findings demonstrate that the key role of social impact measurement is to define SII and, therefore, we cannot study SII without studying social impact measurement. Second, the detailed analysis of SII shows how, contesting both social entrepreneurship finance and a social impact market, the incumbents mobilize a new Impact Economy, in an attempt to come up with a more sustainable version of capitalism. As a result, the core promise of SII is being degraded and used as a marketing tool for increasing the symbolic capital of the financial sector and other groups. Third, the analysis indicates that the theoretical assemblage of Field Theory and Market Devices helps us to understand the activity and development of this field, allowing us to see how actors shape the field through the production, distribution and consumption of devices according to their worldviews and intentions, in an attempt to maintain their position in the field and improve their capital. By understanding that actors use dominant devices to improve their positions, devices become a new type of Bourdieu’s capital – an objectified and embodied cultural capital – and are proposed as key analytical units of fields to shape interactions and practices.

description: We put forward a first-principle NonEquilibrium Green's Function (NEGF) approach to calculate the transient photoabsorption spectrum of optically thin samples. The method can deal with pump fields of arbitrary strength, frequency and duration as well as for overlapping and nonoverlapping pump and probe pulses. The electron-electron repulsion is accounted for by the correlation self-energy, and the resulting numerical scheme deals with matrices that scale quadratically with the system size. Two recent experiments, the first on helium and the second on krypton, are addressed. For the first experiment we explain the bending of the Autler-Townes absorption peaks with increasing the pump-probe delay $\t$, and relate the bending to the thickness and density of the gas. For the second experiment we find that sizable spectral structures of the pump-generated admixture of Kr ions are fingerprints of {\em dynamical correlation} effects, and hence they cannot be reproduced by time-local self-energy approximations. Remarkably, the NEGF approach also captures the retardation of the absorption onset of Kr$^{2+}$ with respect to Kr$^{1+}$ as a function of $\t$.
