description: The article reflects the experience of teaching an interactive seminar on the topic of rewriting the history of eighteenth-century literature through non-canonical texts. As such, the article considers firstly how to introduce graduate students to the revisionist scholarly debate recasting eighteenth-century literature and secondly how to adapt it in a way that is more relatable to them as digital natives with their concomitant mediatic skills. Attempting a participative literary historiography where students put together a new body of literature based on ‘derivatives’ (excerpts, abridgments, unauthorized imitations, or continuations of originals found on online databases) calls for a systematizing frame. The article proposes to achieve this through the preparatory reading of a choice of canonical works that reflect the contemporary critical responses to the proliferation of print. Not only does this first step avoid the dispersion of participants’ findings, but it also helps participants toward an easier understanding of the Foucauldian dynamics of discourse and how they inform his key notion of the author function and, ultimately, of the literary canon. By the time participants turn to choosing a derivative text in the second half of the course, the article argues, they have a clearer sense of the revisionist importance of such an endeavour.

description: We study vertical jumping in a simple robot comprising an actuated mass-spring arrangement. The actuator frequency and phase are systematically varied to find optimal performance. Optimal jumps occur above and below (but not at) the robot's resonant frequency $f_0$. Two distinct jumping modes emerge: a simple jump which is optimal above $f_0$ is achievable with a squat maneuver, and a peculiar stutter jump which is optimal below $f_0$ is generated with a counter-movement. A simple dynamical model reveals how optimal lift-off results from non-resonant transient dynamics.

On the (Mis)Use of Critical Discourse in Architecture: “Experimental Criticism” and its Entanglement with Postreform Art Movement in China
Creators: name: Chen, Dijia
Publisher: name: Histories of Postwar Architecture
Year: 2021

description: Tracing the origins of “experimental criticism” in China’s postreform architectural production, this paper interrogates the established critical discourse centering on the experimental architects, formulated in China’s academic community during the early 2000s. Influenced by liberal art movements after the Cultural Revolution, the experimental architecture emerged as a marginal critique on political totalitarianism and cultural rigidity through installation-like, small-scale and conceptual projects. Despite its peripheral position in the state-regulated production system, experimental architecture was discovered and reframed by the European scholars as the revolutionary rebellions at the turn of the century. It ultimately became the sole protagonist of critical discourse around 2005-06 in Chinese scholarship. The hasty recontextualization of Western criticism and the absence of local architectural theoretical framework have left cultural differentiations unelaborated, resulting in a heated debate over the political implication and social commitment in experimental architecture’s criticality. Prioritizing formalistic operations over pragmatic concerns, the experimental architects were obsessed with the mobilization of Modernist architectural forms and Chinese cultural symbols. The tactful, flexible and even playful outlook of experimental architecture integrated the “Chinese wisdom” and kept in line with the goals and the approaches of the modern art movement. They stand as a problematic figure in the cross-cultural appropriation of architectural criticism to China. In recent years, renewed attention towards the experimental architecture and its successors has drastically increased in both Western and Chinese scholarship, yet the conceptual nuances of experimental criticism that were lost, distorted and reconstructed were never fully elaborated. This paper holds experimental architects’ marginalized position in the socialist production system and their deep entanglement with postreform art movement as the fundamental contributors to the specificities of experimental criticism, and further evaluates its influence on the succeeding commentary and practice paradigms of independent Chinese architects today.

description: A model, applicable to a range of innovation diffusion applications with a strong peer to peer component, is developed and studied, along with methods for its investigation and analysis. A particular application is to individual households deciding whether to install an energy efficiency measure in their home. The model represents these individuals as nodes on a network, each with a variable representing their current state of adoption of the innovation. The motivation to adopt is composed of three terms, representing personal preference, an average of each individual's network neighbours' states and a system average, which is a measure of the current social trend. The adoption state of a node changes if a weighted linear combination of these factors exceeds some threshold. Numerical simulations have been carried out, computing the average uptake after a sufficient number of time-steps over many realisations at a range of model parameter values, on various network topologies, including random (Erdos-Renyi), small world (Watts-Strogatz) and (Newman's) highly clustered, community-based networks. An analytical and probabilistic approach has been developed to account for the observed behaviour, which explains the results of the numerical calculations.
Thinking about De Stijl: Three Generations of Committed Historians in the Netherlands.
Creators: name: Hoekstra, Rixt Rixt
Publisher: name: Histories of Postwar Architecture
Year: 2021

description: This essay focusses on the changing critical identity of the Dutch modern art-and architectural historian in the decades after the Second World War ranging from the 1950s to the early 1990s. By adopting the historisation of De Stijl as a case-study I will state that its post war historiography was not only defined by new insights concerning this avant-garde movement, but equally by a change in the subject position of the historian as a critical actor. In this article the changed relationship between the subject (the historian) and the object (the past) is analysed as the exchange of an engaged attitude for a more detached position in which the past increasingly became the focus of an exclusive cognitive concern. However, this did not mean its results remained unchallenged. In fact, the epistemic turn described in this article went in hand in hand with the rise of postmodernism in the humanities, leading to relativistic claims concerning historical knowledge. Also, an already critical history was further challenged by the arguments of feminist historians. In this way, a univocal history of art was fragmented into a plurality of historical practices. Although these practices were no longer overtly politically engaged they remained politically implicated as the result of the complex correspondences between past and present that remained a part of the histories of artistic modernism.

description: We study the moduli-dependent prefactor of M5-instanton corrections to the superpotential in four-dimensional F-theory compactifications. In light of the M-theory and type IIb limits and also heterotic duality, we propose that the explicit moduli dependence of the prefactor can be computed by a study of zero modes localized at intersections between the instanton and seven-branes. We present an instanton prefactor in an E_6 F-theory GUT which does not admit a heterotic dual and show that it vanishes if and only if a point of E_8 enhancement is present in the instanton worldvolume. More generically, we discuss the relationship between points of E_8 and superpotential zeroes and give sufficient conditions for such a point to cause a zero, even for an SU(5) GUT. We scan a large class of compactifications for instanton physics and demonstrate that many instantons have the same prefactor structure. We discuss the associated implications and complications for moduli stabilization. We present an explicit resolution and construction of G-flux in a generic E_6 GUT and identify a global compactification of the local model spectral cover which happens to facilitate prefactor computations. Via a Leray spectral sequence, we demonstrate the relationship between right-movers of heterotic worldsheet instantons, 3-3 strings of euclidean D3 instantons, and the Fermi zero modes of M5-instantons.

Year: 2021

description: The competition for the German Historical Museum in Berlin was on several layers a controversial project. Already the idea of a museum on German history was fiercely debated, especially in the face of National Socialism. Aldo Rossi’s proposal that won the competition featured a pastiche of typological forms reminiscent of historical German monuments. But critics contested its monumentality and naïve use of iconography, while the jury was accused to have violated competition regulations. The fall of the Berlin Wall eventually ended the debates. This did not go without reaction: The head jury Max Bächer protested to the then-chancellor Helmut Kohl, demanding compensation for Rossi’s lost prize.

description: In an outdoor experimental set-up, the number of Prostephanus truncatus (Horn) flying from maize cobs was recorded over 38 observation weeks. Flight activity in the field was recorded for 50 weeks with three pheromone traps, each placed at c. 100-300 m from the first experimental set-up. Multiple regression analyses revealed that both flight initiation and flight activity were partly influenced by mean temperatures, but were not directly related. Flight initiation was mainly dependent on population density. An additional experiment showed that sex ratios among pheromone trap catches were not correlated with the number of beetles caught; sex ratios were female-biased throughout the year. Seasonal fluctuations in flight activity recorded with pheromone traps are mainly dependent on changes in the number and sizes of beetle populations in a given area, as well as on breeding site availability and suitability.

description: We present a broad-band timing analysis of the accreting white dwarf system MV Lyrae based on data obtained with the Kepler satellite. The observations span 633 days at a cadence of 58.8 seconds and allow us to probe 4 orders of magnitude in temporal frequency. The modelling of the observed broad-band noise components is based on the superposition of multiple Lorentzian components, similar to the empirical modelling adopted for X-ray binary systems. We also present the detection of a frequency varying Lorentzian component in the lightcurve of MV Lyrae, where the Lorentzian characteristic frequency is inversely correlated with the mean source flux. Because in the literature similar broad-band noise components have been associated to either the viscous or dynamical timescale for different source types (accreting black holes or neutron stars), we here systematically explore both scenarios and place constraints on the accretion disk structure. In the viscous case we employ the fluctuating accretion disk model to infer parameters for the viscosity and disk scale height, and infer uncomfortably high parameters to be accommodated by the standard thin disk, whilst in the dynamical case we infer a large accretion disk truncation radius of ~10 white dwarf radii. More importantly however, the phenomenological properties between the broad-band variability observed here and in X-ray binaries and Active Galactic Nuclei are very similar, potentially suggesting a common origin for the broad-band variability.

description: Over the last years, the nature of service has changed owing to conceptual advances and de-velopments in information technology. These developments have given rise to novel types of service and smart service systems (SSS), i.e. resource configurations capable of learning, dy-namic adaptation, and decision-making. Currently, the Internet of Things (IoT) is turning phys-ical objects into active smart things, bridging the gap between the physical and the digital world. Smart things advance SSS as they observe the physical environment, access local data, immerse into individuals’ everyday lives and organizational routines. In line with the emergent nature of both phenomena, the impact of the IoT on SSS yet needs to be explored. Building the basis for explanatory and design-led research and for the analysis and design of SSS, a means for the conceptual modeling of SSS that accounts for novel IoT-enabled concepts is in high need. Hence, we designed, demonstrated, and evaluated a domain-specific modeling language (DSML) for SSS. We evaluated the DSML by using it in the modeling of real-world scenarios from all functional IoT domains, by submitting it to the scrutiny of industry experts, by discuss-ing it against generic DSML requirements, and by analyzing to what extent it meets domain-specific design objectives compared to competing artifacts. To demonstrate the DSML, we in-cluded a complex real-world scenario centered around the Nest Learning Thermostat.

Measurement of high p_T isolated prompt photons in lead-lead collisions at sqrt(s_NN)=2.76 TeV with the ATLAS detector at the LHC

description: Prompt photons are a powerful tool to study heavy ion collisions. Their production rates provide access to the initial state parton distribution functions and also provide a means to calibrate the expected energy of jets that are produced in the medium. The ATLAS detector measures photons with its hermetic, longitudinally segmented calorimeter, which gives excellent spatial and energy resolutions, and detailed information about the shower shape of each measured photon. This provides significant rejection against the expected background from the decays of neutral pions in jets. Rejection against jet fragmentation products is further enhanced by requiring candidate photons to be isolated. First results on the spectra of isolated prompt photons from a dataset with an integrated luminosity of approximately 0.13 nb^-1 of lead-lead collisions at sqrt(s_NN)=2.76 TeV are shown as a function of transverse momentum and centrality. The measured spectra are compared to expectations from perturbative QCD calculations.

description: Conventional three-dimensional crystal lattices are terminated by surfaces, which can demonstrate complex rebonding and rehybridisation, localised strain and dislocation formation. Two dimensional crystal lattices, of which graphene is the archetype, are terminated by lines. The additional available dimension at such interfaces opens up a range of new topological interface possibilities. We show that graphene sheet edges can adopt a range of topological distortions depending on their nature. Rehybridisation, local bond reordering, chemical functionalisation with bulky, charged, or multi-functional groups can lead to edge buckling to relieve strain, folding, rolling and even tube formation. We discuss the topological possibilities at a 2D graphene edge, and under what circumstances we expect different edge topologies to occur. Density functional calculations are used to explore in more depth different graphene edge types.

description: Inspired by the bio-adhesive ability of the marine mussel, highly hydrogen permselective ZIF-8 membranes were prepared on polydopamine functionalized stainless-steel-nets (SSNs). With polydopamine functionalization of SSNs under mild conditions, the nucleation and growth of well-intergrown ZIF-8 membranes were promoted through the formation of strong non-covalent and covalent bonds, which was helpful to enhance the membrane's separation selectivity while maintaining high permeance. For binary mixtures at 100 degrees C and 1 bar, the mixture separation factors of H-2-CO2, H-2-N-2, H-2-CH4 and H-2-C3H8, were found to be 8.1, 15.0, 23.2 and 329.7, which by far exceed the corresponding Knudsen coefficients and those of the as-reported ZIF-8 membranes. The ZIF-8 membranes also displayed high permeances, with the H-2 permeance higher than 2.1 x 10(-5) mol m(-2) s(-1) Pa-1 due to the high void volume of the SSNs.

The microstructure of the crystalline 40NSFO-60CNO phase was investigated by combined in situ X-ray diffraction (XRD), scanning electron microscopy (SEM), back scattered SEM (BSEM), and energy dispersive X-ray spectroscopy (EDXS) analyses. Oxygen permeation and long-time stability under CO2 and CH4 atmospheres were investigated. A stable oxygen flux of 0.21 cm(3) min(-1) cm(-2) at 950 degrees C with undiluted CO2 as sweep gas is found which is increased to 0.48 cm(3) min(-1) cm(-2) if the air side is coated with a porous La0.6Sr0.4CoO3-delta (LSC) layer. All the experimental results demonstrate that the 40NSFO-60CNO not only shows good reversibility of the oxygen permeation fluxes upon temperature cycling, but also good phase stability in a CO2 atmosphere and under the harsh conditions of partial oxidation of methane to synthesis gas up to 950 degrees C.

description: Accurately determining the properties of stars is of prime importance for characterizing stellar populations in our Galaxy. The field of asteroseismology has been thought to be particularly successful in such an endeavor for stars in different evolutionary stages. However, to fully exploit its potential, robust methods for estimating stellar parameters are required and independent verification of the results is mandatory. With this purpose, we present a new technique to obtain stellar properties by coupling asteroseismic analysis with the InfraRed Flux Method. By using two global seismic observables and multi-band photometry, the technique allows us to obtain masses, radii, effective temperatures, bolometric fluxes, and hence distances for field stars in a self-consistent manner. We apply our method to 22 solar-like oscillators in the Kepler short-cadence sample, that have accurate Hipparcos parallaxes. Our distance determinations agree to better than 5%, while measurements of spectroscopic effective temperatures and interferometric radii also validate our results. We briefly discuss the potential of our technique for stellar population analysis and models of Galactic Chemical Evolution.

description: Due to Bangladesh's tropical environment and fertile soil, an enormous amount of agricultural goods have a significant economic influence. However, in the southern region, developing an effective controlling, preserving, and delivery system for the agricultural product was extremely difficult. Many chances for planning, procurement, and transportation of this agricultural commodity are made possible by the Padma Bridge. Padma Bridge improves farmers' production levels from the point of origin to the point of consumption. It also boosts storage and preservation capacity, transportation system efficiency, and market strategy analysis. In this scenario, managing farmers' inclusion, logistical assistance, and supply chain management in the agro system is an issue.

Moreover, compounds 3b and 3g showed high potency against the HeLa and MDA-MB-231 cell lines having IC50 in the range of 2.38–9.72 μM. These compounds are more selective for the tested human cancer cells than for the mouse fibroblast cell line (NIH/3T3). As a result of the studies conducted in order to understand the molecular mechanism, compounds 3b and 3g enhanced expression of the caspase-3 pro-apoptotic proteins levels besides caspase-3 gene.

description: A model of a cloud formed by massive strings is used as a source of Bianchi type II. We assumed that the expansion $(θ)$ in the model is proportional to the shear $(σ)$. To get exact solution, we have considered the equation of state of the fluid to be in the stiff form. It is found that the bulk viscosity plays a very important rule in the history of the universe. In presence of bulk viscosity the particles dominate over strings whereas in absence of it, strings dominate over the particles which is not in consistence with the recent observations. Also we observe that the viscosity caused the expansion of the universe to be accelerating. Our models are evolving from an early decelerating phase to a late time accelerating phase. The physical and geometrical behavior of these models are discussed.

description: We show that the degree of spin polarization of photoelectrons from the surface states of topological insulators is 100% if fully-polarized light is used as in typical photoemission measurements, and hence can be significantly "higher" than that of the initial state. Further, the spin orientation of these photoelectrons in general can also be very different from that of the initial surface state and is controlled by the photon polarization; a rich set of predicted phenomena have recently been confirmed by spin- and angle-resolved photoemission experiments.

description: A series of 9-position substituted triptycene derivatives were synthesized from 9-substituted anthracenes. Diels–Alder reaction was the key reaction to form the scaffold; both benzoquinon and aryne were studied as dienophile. The diastereomers of triptycene 10a were separated by chiral high-performance liquid chromatography (HPLC) column.
Sommerfeld effect in heavy quark chemical equilibration

description: The chemical equilibration of heavy quarks in a quark-gluon plasma proceeds via annihilation or pair creation. For temperatures T much below the heavy quark mass M, when kinetically equilibrated heavy quarks move very slowly, the annihilation in the colour singlet channel is enhanced because the quark and antiquark attract each other which increases their probability to meet, whereas the octet contribution is suppressed. This is the so-called Sommerfeld effect. It has not been taken into account in previous calculations of the chemical equilibration rate, which are therefore incomplete for T < alphas^2 M. We compute the leading-order equilibration rate in this regime; there is a large enhancement in the singlet channel, but the rate is dominated by the octet channel, and therefore the total effect is small. In the course of the computation we demonstrate how operators that represent the annihilation of heavy quarks in non-relativistic QCD can be incorporated into the imaginary-time formalism.

description: Both psychological and entrepreneurship research emphasize the pivotal role of job satisfaction in the process of entrepreneurial career decisions. In fact, a co-relationship between entrepreneurial intention, job satisfaction, and organizational commitment was demonstrated recently. Prior research operationalized entrepreneurial careers as an escape from poor work environments; thus, there is a lack of understanding regarding how job-satisfaction and outcome expectations can motivate and trigger academic entrepreneurship within and related to the environment of universities (e.g., spin-off activities). In this study, drawing on Social Cognitive Career Theory delineated by Lent and colleagues and the concept of entrepreneurial intention, we addressed the role of job satisfaction as a moderating factor between outcome expectations and entrepreneurial intention. Furthermore, we examined to what extent (a) entrepreneurial intention and (b) spin-off intention are determined by certain outcome expectations and perceived behavioral control. This paper purports to study academic researchers in specialized and non-technical fields and builds on a survey of 593 academic researchers at Swiss Universities of Applied Science (UAS). Supporting our hypothesis, we showed that outcome expectations are a significant predictor for entrepreneurial intentions, in general, and spin-off intentions, in particular. Finally, a multi-group analysis corroborated that job dissatisfaction partly operates as a motivational factor in entrepreneurial transition and interactions with entrepreneurial outcome expectations. In conclusion, the concept of job satisfaction and the theoretical approach of Social Cognitive Career Theory seems to be relevant to study and to encourage academic entrepreneurship as career decisions of the academic researchers.
A new CO2-resistant Ruddlesden-Popper oxide with superior oxygen transport: A-site deficient (Pr0.9La0.1)1.9(Ni0.74Cu0.21Ga0.05)O4+δ

description: A-site deficient (Pr0.9La0.1)1.9Ni0.74Cu0.21Ga0.05O4+δ ((PL)1.9NCG), with the K2NiF4 structure, is found to exhibit higher oxygen transport rates compared with its cation-stoichiometric parent phase. A stable oxygen permeation flux of 4.6 × 10−7 mol cm−2 s−1 at 900 °C at a membrane thickness of 0.6 mm is measured, using either helium or pure CO2 as sweep gas at a flow rate of 30 mL min−1. The oxygen flux is more than two times higher than that observed through A-site stoichiometric (PL)2.0NCG membranes operated under similar conditions. The high oxygen transport rates found for (PL)1.9NCG are attributed to highly mobile oxygen vacancies, compensating A-site deficiency. The high stability against carbonation gives (PL)1.9NCG potential for use, e.g., as a membrane in oxy-fuel combustion processes with CO2 capture.

Random l-colourable structures with a pregeometry

description: We study finite $l$-colourable structures with an underlying pregeometry. The probability measure that is used corresponds to a process of generating such structures (with a given underlying pregeometry) by which colours are first randomly assigned to all 1-dimensional subspaces and then relationships are assigned in such a way that the colouring conditions are satisfied but apart from this in a random way. We can then ask what the probability is that the resulting structure, where we now forget the specific colouring of the generating process, has a given property. With this measure we get the following results: 1. A zero-one law. 2. The set of sentences with asymptotic probability 1 has an explicit axiomatisation which is presented. 3. There is a formula $ξ(x,y)$ (not directly speaking about colours) such that, with asymptotic probability 1, the relation "there is an $l$-colouring which assigns the same colour to $x$ and $y$" is defined by $ξ(x,y)$. 4. With asymptotic probability 1, an $l$-colourable structure has a unique $l$-colouring (up to permutation of the colours).

description: We conduct a comprehensive comparison of market beta estimation techniques. We study the performance of several historical, time-series model, and option-implied estimators for estimating realized market beta. Thereby, we find the hybrid methodology of Buss and Vilkov to consistently outperform all other approaches. In addition, all other approaches, including fully implied and dynamic conditional beta, based on generalized autoregressive conditional heteroskedasticity (GARCH) models, are dominated by a simple beta estimate based on historical (co-)variances and an approach based on the Kalman filter. Our conclusions remain unchanged after performing several robustness checks.

description: We develop a novel approach for pricing cyber insurance contracts. The considered cyber threats, such as viruses and worms, diffuse in a structured data network. The spread of the cyber infection is modeled by an interacting Markov chain. Conditional on the underlying infection, the occurrence and size of claims are described by a marked point process. We introduce and analyze a new polynomial approximation of claims together with a mean-field approach that allows to compute aggregate expected losses and prices of cyber insurance. Numerical case studies demonstrate the impact of the network topology and indicate that higher order approximations are indispensable for the analysis of non-linear claims. © 2018 by Astin Bulletin.

Avalanche Mechanism for the Enhanced Loss of Ultracold Atoms

description: In several experiments with ultracold trapped atoms, a narrow loss feature has been observed near an {\it atom-dimer resonance}, at which there is an Efimov trimer at the atom-dimer threshold. The conventional interpretation of these loss features is that they are produced by the {\it avalanche mechanism}, in which the energetic atom and dimer from 3-body recombination undergo secondary elastic collisions that produce additional atoms with sufficient energy to escape from the trapping potential. We use Monte Carlo methods to calculate the average number of atoms lost and the average heat generated by recombination events in a Bose-Einstein condensate and in a thermal gas. We improve on previous models by taking into account the energy-dependence of the cross sections, the spacial structure of the atom cloud, and the elastic scattering of the atoms. We show that the avalanche mechanism cannot produce a narrow loss feature near the atom-dimer resonance. The number of atoms lost from a recombination event can be more than twice as large as the 3 that would be obtained in the absence of secondary collisions. However the resulting loss feature is broad and its peak is at a scattering length that is larger than the atom-dimer resonance and depends on the trap depth.

description: A clean and highly efficient chemical method was developed for the synthesis of hydrophilic nickel phosphate nanoparticles and the formation of nanoparticles was confirmed by discrete spectral techniques. The synthesized nanoparticles were found to be an efficient catalyst for transfer hydrogenation of aromatic nitro compounds. The reaction was carried out at room temperature using sodium borohydride as the hydrogen donor and the reaction was successful with remarkable yields.
