description: Knowledge about how the nonlinear behaviour of the intrinsic signal from lensed background sources changes on its path to the observer provides much information, particularly about the matter distribution in lensing galaxies and the physical properties of the current universe, in general. Here, we analyse the multifractal (nonlinear) behaviour of the optical observations of A and B images of Q0957+561 in the $r$ and $g$ bands. AIMS: To verify the presence, or absence, of extrinsic variations in the observed signals of the quasar images and investigate whether extrinsic variations affect the multifractal behaviour of their intrinsic signals. METHOD: We apply a wavelet transform modulus maxima-based multifractality analysis approach. RESULTS: We detect strong multifractal (nonlinear) signatures in the light curves of the quasar images. The degree of multifractality for both images in the $r$ band changes over time in a non-monotonic way, possibly indicating the presence of extrinsic variabilities in the light curves of the images, i.e., the signals of the quasar images are a combination of both intrinsic and extrinsic signals. Additionally, in the r band, in periods of quiescent microlensing activity, we find that the degree of multifractality (nonlinearity) of image A is stronger than that of B, while B has a larger multifractal strength in recent epochs (from day 5564 to day 7527) when it appears to be affected by microlensing. Finally, comparing the optical bands in a period of quiescent microlensing activity, we find that the degree of multifractality is stronger in the $r$ band for both quasar images. In the absence of microlensing, the observed excesses of nonlinearity are most likely generated when the broad-line region (BLR) reprocesses the radiation from the compact sources.

Gezondheid werd vanouds gedefinieerd als een toestand van volledig welzijn waarin ziekte afwezig is. Nu wordt gezondheid steeds meer gezien als het dynamisch vermogen van mensen om zich door moeilijkheden heen te slaan. Deze zienswijze legt sterk de nadruk op de individuele veerkracht. Hoe kunnen mensen met behulp van de experience sampling methode (ESM) zelf factoren in hun dagelijks leven in kaart brengen die hun veerkracht beïnvloeden?
Shape-Dependent Thermodynamics and Non-Local Hydrodynamics in a Non-Gibbsian Steady-State of a Drift-Diffusion System

description: Shape-dependent thermodynamics and non-local hydrodynamics are argued to occur in dissipative steady states of driven diffusive systems. These predictions are confirmed by numerical simulations. Unlike power-law correlations, these phenomena cannot be explained by a hypothesis of ``criticality''. Instead, they require the effective Hamiltonian of the system to contain very long-range potentials, making the invariant probability measures formally ``non-Gibbsian''.

description: Numerical simulations of the two-dimensional t-J model in the limit $J/t \ll 1$ are performed for rather large systems (up to $N = 12 \times 12$) using a world-line loop-algorithm. It is shown that in the one-hole case with J=0, where no minus signs appear, very low temperatures ($βt \sim 3000$) are necessary in order to reach Nagaoka's state. $J/t \ltsim 0.05$ leads to the formation of partially polarized systems, whereas $J/t \gtsim 0.05 $ corresponds to minimal spin. The two-hole case shows enhanced total spin up to the lowest attainable temperatures ($βt = 150$).

Dynamical Properties in the Bilayer Quantum Hall Ferromagnet

description: The spectral functions of the pseudospin correlation functions in the bilayer quantum Hall system at ν=1 are investigated numerically, where the pseudospin describes the layer degrees of freedom. In the pseudospin-ferromagnetic phase, the lowest-energy excitation branch is closely connected with the ground state through the fluctuations of pseudospin S_y and S_z, and it plays a significant role on the tunneling properties in this system. For the system with very small tunneling amplitude and layer separation smaller than the critical one, the system-size dependence of calculated spectral function A_{y z} suggests the superfluidity on the tunneling current in the absence of impurities.

Topo[graphies] of the Un/conscious
Creators: name: Martin, Bea
Publisher: name: AIS - Architecture Image Studies
Year: 2020

description: The topography that entertains the unconscious includes inhabitants and the forms of their passage through spaces. A landscape of vessels, a place that both “holds and moves”. This is an e-motional field, where the topographic relationships of component parts are not stable and fixed; rather, they can be mis-placed, dis-placed, or even re-placed. The type of topography foregrounded here is a projected landscape of the unconscious. A field through which all our experiential memories are mediated – a ‘field of being’. This article explores how architectural space registers in such a field. The narrative is assembled as a montage of verbal and visual constructs and routing in the form of mental frames. This includes a graphic exploration of cognitive processes and their visual representation, a structural mapping of mental space through frames and folds of memory, as well as the tectonic field in which the psychoanalytic encounter between narrator and narrative takes place on a drawing.

description: Porous boron nitride (PBN) as an emerging porous material exhibits unique physico-chemical properties for environmental remediation. However, the practical applications of PBN are very difficult due to its poor regeneration performance. In this work, we loaded α-Fe2O3 nanoparticles on PBN to form a kind of composite (HB) with high adsorption capacity, which possessed remarkably enhanced regeneration performance. As expected, HB exhibited excellent synergistic catalytic degradation activity with the assistance of H2O2 towards methylene blue (MB) adsorbed on its surface: after 10 cycles, the removal efficiency of 92.8% for HB remained. Further experiments revealed that the α-Fe2O3 nanoparticles accelerated the decomposition of H2O2 to produce ·O2 radicals and ·OH radicals, which could degrade the dye adsorbed on their surface directly. Given the high adsorption capacity and excellent recyclability, HB is envisaged to be valuable practically for water purification and meets the requirement of large-scale production.

description: This paper deals with some two-parameter solutions to the spherically symmetric, vacuum Einstein equations which, we argue, are more general than de Sitter solution. The global structure of one such spacetimes and its extension to the multiply connected case have also been investigated. By using a six-dimensional Minkowskian embedding as its maximal extension, we check that the thermal properties of the considered solution in such an embedding space are the same as those derived by the usual Euclidean method. The stability of the generalized de Sitter space containing a black hole has been investigated as well by introducing perturbations of the Ginsparg-Perry type in first order approximation. It has been obtained that such a space perdures against the effects of these perturbations.

description: MAXI J1807+132 is an X-ray transient discovered during the decay of an outburst in 2017. We present optical and X-ray monitoring of the source over more than 125 days, from outburst to quiescence. The outburst decay is characterized by the presence of several re-flares with a quasi-periodic recurrence time of $\sim 6.5$ days. We detect broad H and He emission lines during outburst, characteristic of transient low mass X-ray binaries. These emission lines show strong variability from epoch to epoch and, in particular, during the early stages are found embedded into deep and very broad absorption features. The quiescent spectrum shows H$α$ in emission and no obvious signatures of the donor star. XMM-Newton and Swift spectra can be fitted with standard X-ray models for accreting black-holes and neutron stars, although the obtained spectral parameters favour the latter scenario. Conversely, other observables such as the optical/X-ray flux ratio, the likely systemic velocity ($γ\sim -150$ km s$^{-1}$) and the re-flares recurrence time suggest a black hole nature. We discuss all the above possibilities with emphasis on the strong similarities of MAXI J1807+132 with short orbital period systems.

description: Vacuum polarization of massive scalar fields in a thermal state at arbitrary temperature is studied near the horizon of a Reissner-Nordström black hole. We derived an analytic form of $$ approximately in the large mass limit near the black hole horizon. We uses the zeroth order WKB approximation and power series expansion near the horizon for the Euclideanized mode function. Our formula for the vacuum polarization shows regular behavior on the horizon if the temperature of the scalar field is equal to the Hawking temperature of the black hole. The finite part of the vacuum polarization agrees with the result of the DeWitt-Schwinger approximation up to $O(m^{-4})$ which is the next leading order of the expansion.

description: The purpose of the present thesis, is to compare the geological ang geotechnical estimations derived from the geotechnical investigations along the Kalydona tunnel of Ionia Odos and th conditions that were encountered during the excavation of the tunnel. In addition and effort has been made to define the possible kinematic failures of the portal slopes according to the tectonic diagrams and then to compare them with the actual state presented during the excavation. Initially the geological - tectonic and hydrogeological conditions of the wider area are described and afterwards the geotechnical conditions along Kalydona tunnel are presented. Then is defined the stabilith of the portal slopes according to the tectonic diagrams and also the proposed primary support measures are mentioned. In the end the 'as built' geotechnical data resulted from the 'in situ' observations and also the applied primary support measures are provided. Finally the predicted geotechnical conditions are compared with the actual ones encounterec and also the predicted primary support measures are compared with the ones applied.
Drawing Drawings: Towards a Narrative Architecture

description: This introductory article opens the subject matter of the second issue of AIS, Narrative Architecture. Drawings have always contained the possibility of being more radical than the architecture they represent. Given the status of architecture within the current building industry, architecture needs to be oppositional to the values of laissez-faire capitalism and its environmentally catastrophic consequences. In many ways, the development of digital forms of representation has freed the architectural drawing from its historic association with its role as a vector for traditional forms of building. Architects no longer need to make drawings for buildings, but now have the opportunity to make drawings for other things.

description: The purpose of this work is to find the time dependent distributions of directions and positions of a particle that undergoes multiple elastic scattering. The angular cross section is given and the scatterers are randomly placed. The distribution of directions is found. As for the second distribution we find an exact expression for isotropic cross section in 2 dimensions. For the same cross section we find its Fourier-Laplace transform in 3 dimensions. For the general case we devise a method to compute the Fourier-Laplace transform with arbitrary precision. This work is based not on the Boltzmann transport equation but on an integral equation formulation of the problem. The results are general in the sense that any initial condition is a linear combination of the cases considered in this article.

The incommensurate charge-density-wave instability in the extended three-band Hubbard model

description: The infinite-U three-band Hubbard model is considered in order to describe the CuO_2 planes of the high temperature superconducting cuprates. The charge instabilities are investigated when the model is extended with a nearest-neighbor repulsion between holes on copper d and oxygen p orbitals and in the presence of a long-range Coulombic repulsion. It is found that a first-order valence instability line ending with a critical point is present like in the previously investigated model without long-range forces. However, the dominant critical instability is the formation of incommensurate charge-density-waves, which always occur before the valence-instability critical point is reached. An effective singular attraction arises in the proximity of the charge-density wave instability, accounting for both a strong pairing mechanism and for the anomalous normal state properties.

description: We note that Eddington's radiation damping calculation of a spinning rod fails to account for the complete mass integral as given by Tolman. The missing stress contributions precisely cancel the standard rate given by the 'quadrupole formula'. This indicates that while the usual 'kinetic' term can properly account for dynamical changes in the source, the actual mass is conserved. Hence gravity waves are not carriers of energy in vacuum. This supports the hypothesis that energy including the gravitational contribution is confined to regions of non-vanishing energy-momentum tensor $T_{ik}$. PACS numbers: 04.20.Cv, 04.30.-w

description: A new ''twice loose shoe'' method in the Wheeler-DeWitt equation of the universe wave function on the cosmic scale factor a and a scalar field $ϕ$ is suggested in this letter. We analysis the both affects come from the tunneling effect of a and the potential well effect of $ϕ$, and obtain the initial values $a_0$ and $ϕ_0$ about a primary closed universe which is born with the largest probability in the quantum manner. Our result is able to overcome the ''large field difficulty'' of the universe quantum creation probability with only tunneling effect. This new born universe has to suffer a startup of inflation, and then comes into the usual slow rolling inflation. The universe with the largest probability maybe has a ''gentle'' inflation or an eternal chaotic inflation, this depends on a new parameter q which describes the tunneling character.

Our simulations lead us to the hypothesis that the observed broad incubation time distribution in epidemiological data reflect fluctuation dominated growth seeded by a few nanometer scale aggregates, while much narrower incubation time distributions for innoculated lab animals arise from statistical self averaging. We model `species barriers' to prion infection and assess a related treatment protocol.

description: Data on the occurrence of organophosphate tri-esters (tri-OPEs) and their metabolites (di-OPEs) in hen’s eggs are scarce. Therefore, 200 egg samples were gathered in 2023 in Hanoi, Vietnam and analysed by UHPLC-Q-Exactive HRMS. The majority of these compounds were detected, with tris(2-ethylhexyl) phosphate (0.10–2.7 ng/g wet weight (ww)) and trihexyl phosphate (0.08–2.3 ng/g ww) being the most prevalent tri-OPEs. Significant differences in tri-OPE profiles were observed in egg samples from battery-cage and free-range farming (p < .05). Despite egg levels ranging from 0.05 to 11.2 ng/g ww, Σdi-OPE accumulation in yolk and egg white was not significantly different in (p > .05). Among di-OPEs, dibutyl phosphate was found at the highest levels in the egg white, while bis(2-ethylhexyl) phosphate had the highest levels in yolk. There was no carcinogenic human health risk associated with OPEs in eggs (HQs <1).

description: This study provides occurrence data for acrylamide in various foodstuffs, including those covered by Recommendation (EU) 2019/1888, from 210 samples purchased on the Belgian market. Detection frequencies exceeded 84% in potato-based products other than fries, vegetable crisps, black olives, cocoa powders, coffee substitutes and cereals and snacks. Large variations in acrylamide levels were found in cereals and snacks, with no correlation between cereal type or processing. Snacks containing chia did not show higher acrylamide levels than other cereal-based snacks. Maximum levels found were 4389 and 3063 µg kg−1 in coffee substitutes and vegetable crisps, respectively. Potato-based products contained 2 to 27 times less acrylamide when prepared in oven, compared to deep fryer processing. Artificially oxidised “Californian-style” black olives contained five times more acrylamide than “Greek-style” olives. In bread, pastries, nuts, oilseeds, dried fruits and confectionaries, detection frequencies varied from 27 to 69% and the average acrylamide content was <30 µg kg−1.

description: A generic form of low-energy effective action of superstring theories with one-loop quantum correction is well known. Based on this action we derive the complete perturbation equations and general analytic solutions in the cosmological spacetime. Using the solutions we identify conserved quantities characterizing the perturbations: the amplitude of gravitational wave and the perturbed three-space curvature in the uniform-field gauge both in the large-scale limit, and the angular-momentum of rotational perturbation are conserved independently of changing gravity sector. Implications for calculating perturbation spectra generated in the inflation era based on the string action are presented.

description: The society of the network is one that is more connected than ever through the ubiquity of cybernetic activity, yet this has been paralleled by fragmentation of space and de-localisation of place. This speculative project explores a re-conception of perceived space in response to contemporary trends in social practice. Contextualised against a backdrop between post-scarcity and singularity, the project encompasses the formation of an urban network fabric that provides a framework for utopian social emergence. An infrastructural armature that produces emergent, machinic artefacts, dispersed along the landscape. The spaces of possibilities developed within this framework, speculate on the merger of virtual and physical space, contending to show a realisation of collective agency within spatial production.

We have found that the consideration of noise changes drastically the behavior of the system and leads to new situations which have no counterpart in the deterministic case. Among others, noise is responsible for temporal oscillations, spatial patterns, and the enhancement of the response of the system via stochastic resonance.

Self-similar spherically symmetric cosmological models with a perfect fluid and a scalar field

Year: 2000

description: Self-similar, spherically symmetric cosmological models with a perfect fluid and a scalar field with an exponential potential are investigated. New variables are defined which lead to a compact state space, and dynamical systems methods are utilised to analyse the models. Due to the existence of monotone functions global dynamical results can be deduced. In particular, all of the future and past attractors for these models are obtained and the global results are discussed. The essential physical results are that initially expanding models always evolve away from a massless scalar field model with an initial singularity and, depending on the parameters of the models, either recollapse to a second singularity or expand forever towards a flat power-law inflationary model. The special cases in which there is no barotropic fluid and in which the scalar field is massless are considered in more detail in order to illustrate the asymptotic results. Some phase portraits are presented and the intermediate dynamics and hence the physical properties of the models are discussed.

This connective tissue becomes the fodder for a new site for architectural speculation. The palimpsest and pentimento both become the notation and annotation in a new set of investigational works.

description: We use the Kubo formalism to evaluate the contribution of acoustic phonon exchange to the frictional drag between nearby two-dimensional electron systems. In the case of free phonons, we find a divergent drag rate ($τ_{D}^{-1}$). However, $τ_{D}^{-1}$ becomes finite when phonon scattering from either lattice imperfections or electronic excitations is accounted for. In the case of GaAs quantum wells, we find that for a phonon mean free path $\ell_{ph}$ smaller than a critical value, imperfection scattering dominates and the drag rate varies as $ln (\ell_{ph}/d)$ over many orders of magnitude of the layer separation $d$. When $\ell_{ph}$ exceeds the critical value, the drag rate is dominated by coupling through an electron-phonon collective mode localized in the vicinity of the electron layers. We argue that the coupled electron-phonon mode may be observable for realistic parameters. Our theory is in good agreement with experimental results for the temperature, density, and $d$-dependence of the drag rate.

Publisher: name: AIS - Architecture Image Studies
Year: 2020

description: Communicating Vessels is a self-instigated, drawn and written theoretical architectural design project. The project re-examines traditional paradigms and elements of garden design such as the gazebo, the garden shed, walled garden, bird bath, entrance gates, riverside seats, love seats, vistas, sculptures, fountains, topiary and outside grown rooms among many other objects and spaces. It redesigns them, electronically connects them, explores their virtual and actual materiality, and their cultural and mnemonic importance, and reassesses them in the wake of the impact of advanced technology on the protocols of contemporary architectural design in the twenty-first century. At the projects, centre is the Longhouse.

Gezelschapsdieren spelen een belangrijke rol in de Nederlandse samenleving. Veelal wordt een huisdier beschouwd als een lid van het gezin en ervaren mensen een hechte band met het dier. Waarom vallen we massaal voor de charmes van een hond of kat? Is dat alleen maar vanwege de gezelligheid die zij te bieden hebben, of ontlenen we meer aan hun aanwezigheid?
Emerging Architectural Spatialities
Creators: name: Manfredini, Manfredo
Publisher: name: AIS - Architecture Image Studies
Year: 2020

description: Intersections between cinema and architecture originated when moving images started recording actual buildings and urban environments and, from their inception, they have been accompanied by extended theoretical reflections on authenticity and objectivity of spatial representation. In recent times, disruptive transformations in the modes and techniques of architectural expression introduced by digital production have originated a fundamental rethinking of these questions. Looking at the impact of technology advances on mechanisms of spatial narrative in cinema, this paper explores how the new forms of architectural expression configure elements and contexts that radically challenge the traditional notions of authenticity and objectivity. Although the new forms of visual narration of architecture in cinema are well understood, the way in which they enhance film narrative is not. With the help of relevant philosophical concepts developed by Gilles Deleuze, this study explores this complex architectural phenomenon to shed light on the mechanisms operating behind it by decoding exemplary cases that transcend the conventional limits of spatial individuation. Through a case study on hybrid, complex and multiple speculative spatialities found in the Marvel movie series, this study offers a theoretical frame to understand the emerging architectural typologies and morphologies. By applying assemblage theory to decode these spatialites, this study offers a description of the novel means used in cinema to redefine architectural types and forms by creatively deterritorializing and reterritorializing consolidated ones. Through the engagement with the Deleuzian understanding of the productive capacity of repetition, the new architectural elements are described as assemblages that expand their both material and intangible boundaries, endowing them with narrative forces of differential individuation.

description: We report the synthesis of 7,7ʹ-disubstituted 2,2ʹ-methylenedioxy-1,1ʹ-binaphthyls and demonstrate their application as chiral dopants in the nematic mixture MLC-6260 to produce highly twisted cholesteric phases. Especially mesogenic and/or polarizable groups in the 7,7ʹ-positions of the bridged binaphthyls generate unusually high helical twisting powers.
Electron-Phonon or Hole Superconductivity in $MgB_2$?

description: The BCS electron-phonon mechanism and the unconventional 'hole mechanism' have been proposed as explanations for the high temperature superconductivity observed in $MgB_2$. It is proposed that a critical test of which theory is correct is the dependence of $T_c$ on hole doping: the hole mechanism predicts that $T_c$ will drop rapidly to zero as holes are added, while the electron-phonon mechanism appears to predict increasing $T_c$ for a substantial range of hole doping. Furthermore, the hole mechanism and electron-phonon mechanism differ qualitatively in their predictions of the effect on $T_c$ of change in the $B-B$ distances. We discuss predictions of the hole mechanism for a variety of observables as a function of doping, emphasizing the expected differences and similarities with the electron-phonon explanation. The hole mechanism predicts coherence length and penetration depth to increase and decrease monotonically with hole doping respectively.

description: Thorium-229 is a unique case in nuclear physics: it presents a metastable first excited state Th-229m, just a few electronvolts above the nuclear ground state. This so-called isomer is accessible by VUV lasers, which allows transferring the amazing precision of atomic laser spectroscopy to nuclear physics. Being able to manipulate the Th-229 nuclear states at will opens up a multitude of prospects, from studies of the fundamental interactions in physics to applications as a compact and robust nuclear clock. However, direct optical excitation of the isomer or its radiative decay back to the ground state has not yet been observed, and a series of key nuclear structure parameters such as the exact energies and half-lives of the low-lying nuclear levels of Th-229 are yet unknown. Here we present the first active optical pumping into Th-229m. Our scheme employs narrow-band 29 keV synchrotron radiation to resonantly excite the second excited state, which then predominantly decays into the isomer. We determine the resonance energy with 0.07 eV accuracy, measure a half-life of 82.2 ps, an excitation linewidth of 1.70 neV, and extract the branching ratio of the second excited state into the ground and isomeric state respectively. These measurements allow us to re-evaluate gamma spectroscopy data that have been collected over 40~years.

description: With this article it was intended to approach sketching as a form of representation and its relation to design in architectural education. For this purpose, recent publications focused on sketching and its role in design processes were reviewed, using the theoretical and drawn work of Álvaro Siza Vieira as a guiding thread. Firstly, it was sought to determine the nature of sketching, its purposes and its particularities in educational context. Secondly, the role of sketching in design was explored considering the procedures of recognition, transformation and presentation.
