A democratic audit for Europe in times of emergency
Creators: name: Fossum, John Erik

Publisher: name: Zenodo
Year: 2023

description: The purpose of this paper is to sketch the outline of a Democratic Audit of the pandemic with explicit focus on the European Union. We take as our point of departure that the corona pandemic was understood as a time of emergency, and this understanding was widely shared. Hence, in order to understand the democratic and constitutional implications of the pandemic we need to focus on the nature and conditions of politics in times of emergency. Emergencies can make it hard to deliver democratic politics to normal standards: to hold elections in normal ways; to pass laws by normal democratic procedures without legislatures ceding their powers to executive discretion if not decree; to gather representatives together in parliaments to scrutinise and debate responses to emergencies; to maintain full rights of free speech and assembly at the core of democratic politics. Yet crises, and even emergencies, are likely to be recurring features of our world of fragile, interdependent systems that displace problems with and between themselves. Democracies, therefore, need to define what standards and procedures should apply in an emergency. They will need to think counterfactually and not just historically: to anticipate possible emergencies and not just draw lessons from those experienced. Much recent literature has turned away from the idea of emergency powers as a state of exception outside the normal politics and procedures of the democratic constitutional state. Rather, it asks how the powers and politics of emergency can themselves be embedded in democratic institutions and constitutional procedures.

The paper starts by clarifying what is meant by democratic audit. It thereafter proceeds to discuss how to adapt the democratic audit framework to the special conditions surrounding emergency politics, and thereafter outlines three different positions in the international literature on emergency governance that it holds up against the democratic audit framework. The next part provides an overview of emergency politics criteria as defined by the Council of Europe. These criteria have been devised for the assessment of constitutional democracies understood as states, and therefore need modification to apply to the complex multilevel EU setting. The paper does that by first highlighting some of the distinctive traits of the EU that need to be taken into consideration, and thereafter pulls these elements together to present the outline of a Democratic Audit of the pandemic for the multilevel EU. The final part concludes.

description: Contribution of resolved and unresolved extragalactic point sources to the low-frequency sky spectrum is a potentially non-negligible part of the astrophysical foregrounds for cosmic dawn 21-cm experiments. The clustering of such point sources on the sky, combined with the frequency-dependence of the antenna beam, can also make this contribution chromatic. By combining low-frequency measurements of the luminosity function and the angular correlation function of extragalactic point sources, we develop a model for the contribution of these sources to the low-frequency sky spectrum. Using this model, we find that the contribution of sources with flux density $>10^{-6}\,$Jy to the sky-averaged spectrum is smooth and of the order of a few kelvins at 50--$200\,$MHz. We combine this model with measurements of the galactic foreground spectrum and weigh the resultant sky by the beam directivity of the conical log-spiral antenna planned as part of the Radio Experiment for the Analysis of Cosmic Hydrogen (REACH) project. We find that the contribution of point sources to the resultant spectrum is $\sim0.4\%$ of the total foregrounds, but still larger by at least an order of magnitude than the standard predictions for the cosmological 21-cm signal. As a result, not accounting for the point-source contribution leads to a systematic bias in 21-cm signal recovery. We show, however, that in the REACH case, this reconstruction bias can be removed by modelling the point-source contribution as a power law with a running spectral index. We make our code publicly available as a Python package labelled epspy.

Eluding Zeno effect via dephasing and detuning

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We analyze some variants of the Zeno effect in which the frequent observation of the population of an intermediate state does not prevent the transition of the system from the initial state to a certain final state. This is achieved by considering system observation involving suitably introduced phase shifts and detunings that leads to a rather rich measurement-induced dynamics by the alteration of the interference governing quantum evolution. For initial nonclassical states this includes entanglement as a way of evolution from the initial to the final state avoiding the intermediate state. This possibility is presented in a particular physical scenario in the form of a chain of three coupled harmonic oscillators, but we readily show then that the idea can be applied to other physical systems as well, such as atomic-level dynamics. These results are significant for a better knowledge of fundamental quantum concepts as well as regarding suitable applications in the proper control of quantum dynamics, as this is a key feature of modern applications of the quantum theory.

We investigate the implications of such a scenario for the evolution of both DM and neutrinos in the early Universe, and show that the future cosmic neutrino detection experiment PTOLEMY might be sensitive to neutrino signals that originate from DM annihilation in this model.

Non-Covalent Interaction: Revealed by Rotational Spectroscopy

Subjects: CHIM/02 Chimica fisica

description: The pulsed jet Fourier transform microwave spectroscopy have been applied to several molecular complexes involving H2O, freons, methane, carboxylic acids, and rare gas. The obtained results showcase the suitability of this technique for studying the intermolecular interactions.
The rotational spectra of three water adducts of halogenated organic molecules, i.e. chlorotrifluoroethylene, isoflurane and alfa,alfa,alfa,-trifluoroanisole, have been investigated. It has been found that, the halogenation of the partner molecules definitely changes the way in which water will link to the partner molecule.
Quadrupole hyperfine structures and/or the tunneling splittings have been observed in the rotational spectra of difluoromethane-dichloromethane, chlorotrifluorometane-fluoromethane, difluoromethane-formaldehyde and trifluoromethane-benzene. These features have been useful to describe their intermolecular interactions (weak hydrogen bonds or halogen bonds), and to size the potential energy surfaces of their internal motions. 
The rotational spectrum of pyridine-methane pointed out that methane prefers to locate above the ring and link to pyridine through a C-H•••π weak hydrogen bond, rather than the C-H•••n interaction. This behavior, typical of complexes of pyridine with rare gases, suggests classifying CH4, in relation to its ability to form molecular complexes with aromatic molecules, as a pseudo rare gas.
The conformational equilibria of three bi-molecules of carboxylic acids, acrylic acid-trifluoroacetic acid, difluoroacetic acid-formic acid and acrylic acid-fluoroacetic acid have been studied. The increase of the hydrogen bond length upon H→D isotopic substitution (Ubbelohde effect) has been deduced from the elongation of the carboxylic carbons C•••C distance.
The van der Waals complex tetrahydrofuran-krypton shows that the systematic doubling of the rotational lines has been attributed to the residual pseudo-rotation of tetrahydrofuran in the complex, based on the values of the Coriolis coupling constants, and on the type (mu_b) of the interstate transitions.

description: Supernova remnant (SNR) detection along the Galactic plane poses a number of challenges. The SNR G309.8+00.0 lies exactly on the Galactic plane, with its center coinciding with galactic latitude (b)=0 deg. In this paper we report the first detection of the SNR G309.8+00.0 in X-rays and $γ$ rays, using stacked data from the first four consecutive extended ROentgen Survey Imaging Telescope Array (eROSITA) -- on board the Russian-German Spektrum Roentgen Gamma (SRG) -- all-sky surveys (eRASS:4) and $\sim15.5$ yr of Pass 8 data recorded from Fermi-LAT, respectively. The SNR appears to have an elliptical shape of 0.43 x 0.32 deg in size in both radio synchrotron and X-ray data. The SNR's emission exhibits a shell-like morphology and good spatial correlation in both energy bands. The X-ray emission was solely detected in the 1-2 keV energy band (subject to strong absorption at soft X-rays) and the spectral analysis results of eRASS:4 data present a purely thermal SNR with a high absorption column density $3.1_{-0.5}^{+0.7}\cdot10^{22}~\mathrm{cm^{-2}}$ and a temperature of $0.34\pm0.1$ keV. In combination with optical extinction data, the absorption column density values derived from the remnant's spectral analysis support a remnant's distance greater than 6 kpc, rather than a 3.12 kpc distance as reported in the literature, and yield an age of $1-3.5\cdot10^5$ yr. Employing $\sim15.5$ yr of Fermi-LAT $γ$-ray data at and around the remnant's vicinity, we confirm the detection of the to-date unidentified 4FGL J1349.5-6206c source that can either be modeled as a single source or a conglomerate of multiple distinct source components and we argue that the SNR G309.8+00.0 likely represents at least a significant portion (if not all) of the emission from the 4FGL J1349.5-6206c $γ$-ray source.

description: Pyranine (HPTS) is a remarkably interesting pH sensitive dye that has been used for plenty of applications. Its high quantum yield and extremely sensitive ratiometric fluorescence against pH change makes it a very favorable for pH sensing applications and development of pH nano/microsensors. However, its strong negative charge and lack of easily modifiable functional groups makes it difficult to be used with charged substrates such as silica. This study reports a noncovalent HPTS immobilization methodology on silica microparticles that considers the retention of pH sensitivity as well as long term stability of the pH microsensors. The study emphasizes on importance of surface charge for governing the sensitivity of the immobilized HPTS dye molecules on silica microparticles. Importance of methodology of immobilization that preserves the sensitivity as well as stability of the microsensors is also assessed.

description: Asymptotic behavior of the anomalous dimensions of Wilson operators with high spin and twist is governed in planar N=4 SYM theory by the scaling function which coincides at strong coupling with the energy density of a two-dimensional bosonic O(6) sigma model. We calculate this function by combining the two-loop correction to the energy density for the O(n) model with two-loop correction to the mass gap determined by the all-loop Bethe ansatz in N=4 SYM theory. The result is in agreement with the prediction coming from the thermodynamical limit of the quantum string Bethe ansatz equations, but disagrees with the two-loop stringy corrections to the folded spinning string solution.

description: The Separability Problem is approached from the perspective of Ellipsoidal Classification. A Density Operator of dimension N can be represented as a vector in a real vector space of dimension $N^{2}- 1$, whose components are the projections of the matrix onto some selected basis. We suggest a method to test separability, based on successive optimization programs. First, we find the Minimum Volume Covering Ellipsoid that encloses a particular set of properly vectorized bipartite separable states, and then we compute the Euclidean distance of an arbitrary vectorized bipartite Density Operator to this ellipsoid. If the vectorized Density Operator falls inside the ellipsoid, it is regarded as separable, otherwise it will be taken as entangled. Our method is scalable and can be implemented straightforwardly in any desired dimension. Moreover, we show that it allows for detection of Bound Entangled States

description: In this work, the Generalized Beam Theory (GBT) is used as the main tool to analyze the mechanics of thin-walled beams. After an introduction to the subject and a quick review of some of the most well-known approaches to describe the behaviour of thin-walled beams, a novel formulation of the GBT is presented. This formulation contains the classic shear-deformable GBT available in the literature and contributes an additional description of cross-section warping that is variable along the wall thickness besides along the wall midline. Shear deformation is introduced in such a way that the classical shear strain components of the Timoshenko beam theory are recovered exactly. According to the new kinematics proposed, a reviewed form of the cross-section analysis procedure is devised, based on a unique modal decomposition. Later, a procedure for a posteriori reconstruction of all the three-dimensional stress components in the finite element analysis of thin-walled beams using the GBT is presented. The reconstruction is simple and based on the use of three-dimensional equilibrium equations and of the RCP procedure. Finally, once the stress reconstruction procedure is presented, a study of several existing issues on the constitutive relations in the GBT is carried out. Specifically, a constitutive law based on mirroring the kinematic constraints of the GBT model into a specific stress field assumption is proposed. It is shown that this method is equally valid for isotropic and orthotropic beams and coincides with the conventional GBT approach available in the literature. Later on, an analogous procedure is presented for the case of laminated beams. Lastly, as a way to improve an inherently poor description of shear deformability in the GBT, the introduction of shear correction factors is proposed. Throughout this work, numerous examples are provided to determine the validity of all the proposed contributions to the field.

description: We investigate the evolution of localized initial value profiles when propagated in integrable versions of higher time-derivative theories. In contrast to the standard cases in nonlinear integrable systems, where these profiles evolve into a specific number of N-soliton solutions as dictated by the conservation laws, in the higher time derivative theories the theoretical prediction is that the initial profiles can settle into either two-soliton solutions or into any number of N-soliton solutions. In the latter case this implies that the solutions exhibit oscillations that spread in time but remain finite. We confirm these analytical predictions by explicitly solving the associated Cauchy problem numerically with multiple initial profiles for various higher time-derivative versions of integrable modified Korteweg-de Vries equations. In the case with the theoretical possibility of a decay into two-soliton solutions, the emergence of underlying singularities may prevent the profiles from fully developing or may be accompanied by oscillatory, chargeless standing waves at the origin.

Year: 2018

description: This article presents an ethnographic research project to investigate and report the experiences of refugees in using Facebook groups and pages which are made and run by refugees in their own languages. These ethnic spaces within Facebook, arguably inform refugees about the host society and are spaces of language learning, sharing experiences and finding new friends. Based on the characteristics of such spaces, this research considers them as a type of ethnic media. It is reported by the interviewees that these ethnic spaces, enhance collectiv. This study attempts to further clarify academic understanding of refugee`s experiences in using Facebook ethnic spaces, by looking at the perceptions and self-reports of a sample group of residents of AZC Utrecht, the Netherlands. After briefly addressing the current Dutch asylum process and efforts to help refugees learn the Dutch language, this research explains the findings through interviews with a sample group of refugees and asylum seekers in the AZC Utrecht. For this project, 15 people were interviewed in their residence or public places in the city. They are from Afghanistan, Iran, Iraq, and Syria. The findings of this research indicate that all of the interviewed Persian and Arabic-speaking refugees have memberships in at least one ethnic space within Facebook. They use these spaces for gaining and sharing information about the host society, learning Dutch, reading news about the Netherlands, and to learn about activities for refugees offered by local organizations, as well as making new connections.

description: We address the influence of the orbital symmetry and of the molecular alignment with respect to the laser-field polarization on laser-induced nonsequential double ionization of diatomic molecules, in the length and velocity gauges. We work within the strong-field approximation and assume that the second electron is dislodged by electron-impact ionization, and also consider the classical limit of this model. We show that the electron-momentum distributions exhibit interference maxima and minima due to the electron emission at spatially separated centers. The interference patterns survive the integration over the transverse momenta for a small range of alignment angles, and are sharpest for parallel-aligned molecules. Due to the contributions of transverse-momentum components, these patterns become less defined as the alignment angle increases, until they disappear for perpendicular alignment. This behavior influences the shapes and the peaks of the electron momentum distributions.

description: Environment, Social, and Governance (ESG) KPIs assess an organization's performance on issues such as climate change, greenhouse gas emissions, water consumption, waste management, human rights, diversity, and policies. ESG reports convey this valuable quantitative information through tables. Unfortunately, extracting this information is difficult due to high variability in the table structure as well as content. We propose Statements, a novel domain agnostic data structure for extracting quantitative facts and related information. We propose translating tables to statements as a new supervised deep-learning universal information extraction task. We introduce SemTabNet - a dataset of over 100K annotated tables. Investigating a family of T5-based Statement Extraction Models, our best model generates statements which are 82% similar to the ground-truth (compared to baseline of 21%). We demonstrate the advantages of statements by applying our model to over 2700 tables from ESG reports. The homogeneous nature of statements permits exploratory data analysis on expansive information found in large collections of ESG reports.

alpha'-exact entropies for BPS and non-BPS extremal dyonic black holes in heterotic string theory from ten-dimensional supersymmetry

description: We calculate near-horizon solutions for four-dimensional 4-charge and five-dimensional 3-charge black holes in heterotic string theory from the part of the ten-dimensional tree-level effective action which is connected to gravitational Chern-Simons term by supersymmetry. We obtain that the entropies of large black holes exactly match the alpha'-exact statistical entropies obtained from microstate counting (D=4) and AdS/CFT correspondence (D=5). Especially interesting is that we obtain agreement for both BPS and non-BPS black holes, contrary to the case of R^2-truncated (four-derivative) actions (D-dimensional N=2 off-shell supersymmetric or Gauss-Bonnet) were used, which give the entropies agreeing (at best) just for BPS black holes. The key property of the solutions, which enabled us to tackle the action containing infinite number of terms, is vanishing of the Riemann tensor \bar{R}_{MNPQ} obtained from torsional connection defined with \barΓ = Γ- H/2. Morover, if every monomial of the remaining part of the effective action would contain at least two Riemanns \bar{R}_{MNPQ}, it would trivially follow that our solutions are exact solutions of the full heterotic effective action in D=10. The above conjecture, which appeared (in this or stronger form) from time to time in the literature, has controversial status, but is supported by the most recent calculations of Richards (arXiv:0807.3453 [hep-th]). Agreement of our results for the entropies with the microscopic ones supports the conjecture. As for small black holes, our solutions in D=5 still have singular horizons.

Nutritional studies on high lysine barley lines from the Alberta agriculture breeding program, 1977 harvest
Creators: name: Imbeah, Maleena
Publisher: name: University of British Columbia
Year: 2010

description: Recent years have brought a greater awareness of the need for more plentiful as well as more nutritious foods. Discoveries of strains of maize, barley and other cereals having higher levels of essential amino acids have shown that nutritional quality of cereals can be improved through plant breeding. In the experiments reported here, the nutritional value of three cultivars from the Alberta Agriculture high lysine breeding program (Cultivars 1, 2 and 3), hiproly, and a normal commercial variety was studied. Amino acid analysis was done on each barley line to compare the ability of each to supply essential amino acids. The amino acid composition (g/16 g N) indicated virtually no differences except for cultivar 3 which had a much lower level of total essential amino acids than the rest. Barley proteins were separated by solubility tests to study the proportions in which albumins and globulins, glutelins and hordeins occur and to relate the levels of these protein fractions to the quality of the total protein. Hiproly and cultivars 1 and 2 were found to contain approximately the same levels of albumin plus globulin while cultivar 3 and Gait had lower proportions of these. The latter also had the highest proportion of hordein, an indication that its protein quality is low. Chemical determination of available lysine by dye binding difference gave inconclusive results. However, rat growth assays indicated Hiproly and cultivar 2 to be significantly superior in nutritional quality to Gait and cultivars 1 and 3. Nitrogen balance tests showed no significant differences between any of the five barleys. When the barleys were diluted to a standard protein content (12%), the supplementation with soybean meal or lysine plus other essential amino acids made significant improvements in rat performance, but lysine alone had no beneficial effect. This is an indication that the protein of these high lysine barleys is deficient in essential amino acids other than lysine. Apparent availability of lysine by faecal analysis gave results supporting the fact that high lysine barleys are superior in quality to the normal barley.

Medienbildung im 1. Dienstjahr
Creators: name: Lahner, Bernhard
Publisher: name: Medienimpulse
Year: 2017

description: Nach dem Studium, also jener Zeit, in der sehr viele Ideen zur medienpädagogischen Auseinandersetzung gesammelt werden, ist der Tatendrang groß, endlich in die Umsetzung mit den SchülerInnen zu kommen. Der Schmierzettel mit all den tollen Ideen geht ins Unermessliche. Aber was braucht es jetzt konkret, um in einer öffentlichen Schule tatsächlich Medienpädagogik zu verwirklichen? In diesem Beitrag soll ein selbstkritischer Prozess – mit all den persönlichen und strukturellen Herausforderungen – in Gang sowie ein positiver Blick in die Zukunft geworfen werden.

Curvature dependence of the electrolytic liquid-liquid interfacial tension

description: The interfacial tension of a liquid droplet surrounded by another liquid in the presence of microscopic ions is studied as a function of the droplet radius. An analytical expression for the interfacial tension is obtained within a linear Poisson-Boltzmann theory and compared with numerical results from non-linear Poisson-Boltzmann theory. The excess liquid-liquid interfacial tension with respect to the pure, salt-free liquid-liquid interfacial tension is found to decompose into a curvature-independent part due to short-ranged interfacial effects and a curvature-dependent electrostatic contribution. Several curvature-dependent regimes of different scaling of the electrostatic excess interfacial tension are identified. Symmetry relations of the interfacial tension upon swapping droplet and bulk liquid are found to hold in the low-curvature limit, which, e.g., lead to a sign change of the excess Tolman length. For some systems a low-curvature expansion up to second order turns out to be applicable if and only if the droplet size exceeds the Debye screening length in the droplet, independent of the Debye length in the bulk.

Correction of Radio Interferometric Imaging for Antenna Patterns

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: We describe and demonstrate a technique for correcting direction dependent artifacts due to asymmetries in antenna patterns and differences among antennas used in radio interoferometric imaging. The technique can correct images in all Stokes parameters I, Q, U and V and is shown with simulated data to reduce the level of artifacts to near the level of those from the basic imaging technique. The demonstrations use simulations of a mixed array of 13.5 and 15 m antennas with asymmetric patterns. The flux densities and spectral indices of the sources in a high dynamic range realistic simulated sky model are well recovered. Source polarization properties are also recovered in tests using unpolarized and partly polarized sources. The additional computational run time for Stokes I correction is about 50\% in a realistic test described.

A Renormalized perturbation theory for problems with nontrivial boundary conditions or backgrounds in two space-time dimensions

description: In this paper we discuss the effects of nontrivial boundary conditions or backgrounds, including non-perturbative ones, on the renormalization program for systems in two dimensions. Here we present an alternative renormalization procedure such that these non-perturbative conditions can be taken into account in a self-contained and, we believe, self-consistent manner. These conditions have profound effects on the properties of the system, in particular all of its $n$-point functions. To be concrete, we investigate these effects in the $λϕ^4$ model in two dimensions and show that the mass counterterms turn out to be proportional to the Green's functions which have nontrivial position dependence in these cases. We then compute the difference between the mass counterterms in the presence and absence of these conditions. We find that in the case of nontrivial boundary conditions this difference is minimum between the boundaries and infinite on them. The minimum approaches zero when the boundaries go to infinity. In the case of nontrivial backgrounds, we consider the kink background and show that the difference is again small and localized around the kink.

Derivation of monoclonal antibodies to ferredoxin from Clostridium pasteurianum
Creators: name: Weaver, Michael Stanley
Publisher: name: University of British Columbia
Year: 2010

description: Modifications to the standard techniques of somatic cell fusion are presented which have resulted in the derivation of hybrid cell lines secreting monoclonal antibody to the low molecular weight antigen ferredoxin. Antibody secreted by one of these lines has been purified using the technique of protein. A sepharose chromatography. Using standard immunochemical methods it has been determined that this monoclonal antibody has an approximate isoelectric pH of 8.5 - 8.6 and belongs to the IgG₂[sub b] subclass of immunoglobulin.

description: We compute the scattering amplitude for pion scattering in Wilson chiral perturbation theory for two degenerate quark flavors. We consider two different regimes where the quark mass m is of order (i) aΛ_QCD^2 and (ii) a^2Λ_QCD^3. Analytic expressions for the scattering lengths in all three isospin channels are given. As a result of the O(a^2) terms the I=0 and I=2 scattering lengths do not vanish in the chiral limit. Moreover, additional chiral logarithms proportional to a^2\ln M_π^2 are present in the one-loop results for regime (ii). These contributions significantly modify the familiar results from continuum chiral perturbation theory.

description: Medienkompetenz wird insbesondere in medialen Diskursen als essentielle Befähigung erachtet, um Umgangsformen für den technologischen Wandel zu finden. Mediale Landschaften differenzieren sich laufend aus und werden zunehmend komplexer. Schulen könnten dabei ein Ort sein, um Kindern und Jugendlichen den Umgang mit Medien näher zu bringen. Jedoch hat das Thema in Lehrplänen bis heute kaum Einzug gehalten. Engagierte Lehrende, die sich des Themas annehmen, gibt es. An systemischer Unterstützung, dem passenden Equipment bzw. didaktischem Austausch fehlt es aber. Davon ausgehend beschäftigte sich ein Team von Forschenden mit der Entwicklung von medialen Handlungskompetenzen: Wie entstehen (digitale) Kompetenzen und wie entfalten sich diese im Verlauf eines Lebens? Welche Bedingungen führen zu einem kompetenten Umgang mit Medien? Das Projekt Medienbiographien fragte also nach dem medialen Habitus junger Erwachsener und analysierte welche biografischen Weichenstellungen für unterschiedliche Verläufe ausschlaggebend sind. Ziel des Projekts war die Entwicklung einer Typologie bezüglich digitaler Kompetenzen und eine Dokumentation pädagogischer Best-Practice-Beispiele aus den Schilderungen der Befragten.
