description: The “Chernobyl nuclear disaster” released huge amounts of radionuclides, which are still detectable in plants and sediments today. Bryophytes (mosses) are primitive land plants lacking roots and protective cuticles and therefore readily accumulate multiple contaminants, including metals and radionuclides. This study quantifies 137Cs and 241Am in moss samples from the cooling pond of the power plant, the surrounding woodland and the city of Prypiat. Activity concentrations of up to 297 Bq/g (137Cs) and 0.43 Bq/g (241Am) were found. 137Cs contents were significantly higher at the cooling pond, where 241Am was not detectable. Distance to the damaged reactor, amount of original fallout, presence of vascular tissue in the stem or taxonomy were of little importance. Mosses seem to absorb radionuclides rather indiscriminately, if available. More than 30 years after the disaster, 137Cs was washed out from the very top layer of the soil, where it is no more accessible for rootless mosses but possibly for higher plants. On the other hand, 137Cs still remains solved and accessible in the cooling pond. However, 241Am remained adsorbed to the topsoil, thus accessible to terrestrial mosses, but precipitated in the sapropel of the cooling pond.

description: The next-generation (3G/XG) ground-based gravitational-wave (GW) detectors such as Einstein Telescope (ET) and Cosmic Explorer (CE) will begin observing in the next decade. Due to the extremely high sensitivity of these detectors, the majority of stellar-mass compact-binary mergers in the entire Universe will be observed. It is also expected that 3G detectors will have significant sensitivity down to 2-7 Hz; the observed duration of binary neutron star signals could increase to several hours or days. The abundance and duration of signals will cause them to overlap in time, which may form a confusion noise that could affect the detection of individual GW sources when using naive matched filtering; matched filtering is only optimal for stationary Gaussian noise. We create mock data for CE and ET using the latest population models informed by the GWTC-3 catalog and investigate the performance loss of matched filtering due to overlapping signals. We find the performance loss mainly comes from a deviation in the noise's measured amplitude spectral density. The redshift reach of CE (ET) can be reduced by 15%-38% (8%-21%) depending on the merger rate estimate. The direct contribution of confusion noise to the total signal-to-noise ratio (SNR) is generally negligible compared to the contribution from instrumental noise. We also find that correlated confusion noise has a negligible effect on the quadrature summation rule of network SNR for ET, but might reduce the network SNR of high detector-frame mass signals for detector networks including CE if no mitigation is applied. For ET, the null stream can mitigate the astrophysical foreground. For CE, we demonstrate that a computationally efficient, straightforward single-detector signal subtraction method suppresses the total noise to almost the instrument noise level; this will allow for near-optimal searches.

description: This paper considers a method of coding the sensor outputs in order to detect stealthy false data injection attacks. An intelligent attacker can design a sequence of data injection to sensors and actuators that pass the state estimator and statistical fault detector, based on knowledge of the system parameters. To stay undetected, the injected data should increase the state estimation errors while keep the estimation residues small. We employ a coding matrix to change the original sensor outputs to increase the estimation residues under intelligent data injection attacks. This is a low cost method compared with encryption schemes over all sensor measurements in communication networks. We show the conditions of a feasible coding matrix under the assumption that the attacker does not have knowledge of the exact coding matrix. An algorithm is developed to compute a feasible coding matrix, and, we show that in general, multiple feasible coding matrices exist. To defend against attackers who estimates the coding matrix via sensor and actuator measurements, time-varying coding matrices are designed according to the detection requirements. A heuristic algorithm to decide the time length of updating a coding matrix is then proposed.

description: We investigate the effects of magnetic and nonmagnetic impurities on the two-dimensional surface states of three-dimensional topological insulators (TIs). Modeling weak and strong TIs using a generic four-band Hamiltonian, which allows for a breaking of inversion and time-reversal symmetries and takes into account random local potentials as well as the Zeeman and orbital effects of external magnetic fields, we compute the local density of states, the single-particle spectral function, and the conductance for a (contacted) slab geometry by numerically exact techniques based on kernel polynomial expansion and Green's function approaches. We show that bulk disorder refills the suface-state Dirac gap induced by a homogeneous magnetic field with states, whereas orbital (Peierls-phase) disorder perserves the gap feature. The former effect is more pronounced in weak TIs than in strong TIs. At moderate randomness, disorder-induced conducting channels appear in the surface layer, promoting diffusive metallicity. Random Zeeman fields rapidly destroy any conducting surface states. Imprinting quantum dots on a TI's surface, we demonstrate that carrier transport can be easily tuned by varying the gate voltage, even to the point where quasi-bound dot states may appear.

description: Robust and efficient learning remains a challenging problem in robotics, in particular with complex visual inputs. Inspired by human attention mechanism, with which we quickly process complex visual scenes and react to changes in the environment, we think that embedding auxiliary information about focus point into robot learning would enhance efficiency and robustness of the learning process. In this paper, we propose a novel approach to model and emulate the human attention with an approximate prediction model. We then leverage this output and feed it as a structured auxiliary feature map into downstream learning tasks. We validate this idea by learning a prediction model from human-gaze recordings of manual driving in the real world. We test our approach on two learning tasks - object detection and imitation learning. Our experiments demonstrate that the inclusion of predicted human attention leads to improved robustness of the trained models to out-of-distribution samples and faster learning in low-data regime settings. Our work highlights the potential of incorporating structured auxiliary information in representation learning for robotics and opens up new avenues for research in this direction.

description: By extending the $Φ$-derivable approach in Nambu-Jona-Lasinio model to finite magnetic field we calculate the properties of pion, $σ$ and $ρ$ mesons in a magnetic field at finite temperature in not only the quark-antiquark bound state scheme but also the pion-pion scattering resonant state scenario. Our calculation results manifest that the masses of $π^{0}$ and $σ$ meson can be nearly degenerate at the pseudo-critical temperature which increases with increasing the magnetic field strength, and the $π^{\pm}$ mass ascends suddenly at almost the same critical temperature. While the $ρ$ mesons' masses decrease with the temperature but increase with the magnetic field strength. We also check the Gell-Mann-Oakes-Renner relation and find that the relation can be violated obviously with increasing the temperature, and the effect of the magnetic field becomes pronounced around the critical temperature. With different criteria, we analyze the effect of the magnetic field on the chiral phase transition and find that the pseudo-critical temperature of the chiral phase cross, $T_{c}^χ$, is always enhanced by the magnetic field. Moreover our calculations indicate that the $ρ$ mesons will get melted as the chiral symmetry has not yet been restored, but the $σ$ meson does not disassociate even at very high temperature. Particularly, it is the first to show that there does not exist vector meson condensate in the QCD vacuum in the pion-pion scattering scheme.

description: Strongly correlated insulators are broadly divided into two classes: Mott-Hubbard insulators, where the insulating gap is driven by the Coulomb repulsion $U$ on the transition-metal cation, and charge-transfer insulators, where the gap is driven by the charge transfer energy $Δ$ between the cation and the ligand anions. The relative magnitudes of $U$ and $Δ$ determine which class a material belongs to, and subsequently the nature of its low-energy excitations. These energy scales are typically understood through the local chemistry of the active ions. Here we show that the situation is more complex in the low-dimensional charge transfer insulator Li$_\mathrm{2}$CuO$_\mathrm{2}$, where $Δ$ has a large non-electronic component. Combining resonant inelastic x-ray scattering with detailed modeling, we determine how the elementary lattice, charge, spin, and orbital excitations are entangled in this material. This results in a large lattice-driven renormalization of $Δ$, which significantly reshapes the fundamental electronic properties of Li$_\mathrm{2}$CuO$_\mathrm{2}$.

Spatial asymptotics for the parabolic Anderson models with generalized time-space Gaussian noise

description: Partially motivated by the recent papers of Conus, Joseph and Khoshnevisan [Ann. Probab. 41 (2013) 2225-2260] and Conus et al. [Probab. Theory Related Fields 156 (2013) 483-533], this work is concerned with the precise spatial asymptotic behavior for the parabolic Anderson equation \[\cases{\displaystyle {\frac{\partial u}{\partial t}}(t,x)={\frac{1}{2}}Δu(t,x)+V(t,x)u(t,x),\cr u(0,x)=u_0(x),}\] where the homogeneous generalized Gaussian noise $V(t,x)$ is, among other forms, white or fractional white in time and space. Associated with the Cole-Hopf solution to the KPZ equation, in particular, the precise asymptotic form \[\lim_{R\to\infty}(\log R)^{-2/3}\log\max_{|x|\le R}u(t,x)={\frac{3}{4}}\root 3\of {\frac{2t}{3}}\qquad a.s.\] is obtained for the parabolic Anderson model $\partial_tu={\frac{1}{2}}\partial_{xx}^2u+\dot{W}u$ with the $(1+1)$-white noise $\dot{W}(t,x)$. In addition, some links between time and space asymptotics for the parabolic Anderson equation are also pursued.

description: Pulsars are rapidly spinning and highly magnetized neutron stars, with highly stable rotational period and gradual spin-down over a long timescale due to the loss of radiation. Glitches refer to the events that suddenly increase the rotational speed of a pulsar. The exact causes of glitches and the resulting processes are not fully understood. It is generally believed that couplings between the normal matter and the superfluid components, and the starquakes, are the common causes of glitches. In this study, one famous glitching pulsar, PSR~J2021+4026, is investigated. PSR~J2021+4026 is the first variable gamma-ray pulsar observed by Fermi. From the gamma-ray observations, it is found that the pulsar experienced a significant flux drop, an increase in the spin-down rate, a change in the pulse profile and a shift in the spectral cut-off to a lower energy, simultaneously around 2011 October 16. To explain these effects on the high-energy emissions by the glitch of PSR~J2021+4026, we hypothesized the glitch to be caused by the rearrangement of the surface magnetic field due to the crustal plate tectonic activities on the pulsar which is triggered by a starquake. In this glitch event, the inclination angle of the magnetic dipole axis is slightly shifted. This proposition is then tested by numerical modeling using a three-dimensional two-layer outer gap model. The simulation results indicate that a modification of the inclination angle can affect the pulse profile and the spectral properties, which can explain the observation changes after the glitch.

description: We study the direction- and wavelength-dependent polarization anisotropy in light scattering at the air-photonic crystal interface as a function of angle of incidence for TE and TM polarized light. This is done using optical reflectivity measurements at high-symmetry points in the Brillouin zone of a three-dimensional photonic crystal with fcc symmetry. Polarized reflectivity measurements indicate the presence of stop gap branching for TE polarization, which is absent for TM polarization till the Brewster angle at K point. In contrast, stop gap branching is present for both TE and TM polarizations at W point due to the intricate mixing of crystal planes. This characteristic behavior signifies the inevitable role of energy exchange in the stop gap branching. The measured polarization anisotropy shows a prominent shift in the Brewster angle for on-resonance wavelength as compared to the off-resonance along both K and W points, and that, in accordance with theory. Our results have implications in polarization-induced light scattering in sub-wavelength photonic structures like plasmonic crystals, and meta-materials.

The document contains information on the exploitation plan, which includes potential business models and revenues from citizen activities, data privacy and security issues. Exploitation activities have been carried out, building on the demonstrators as part of REINFORCE monitoring and mentoring actions. Regards sustainability, this is tied to the exploitation of the REINFORCE community and services. Specifically, the plan is for REINFORCE to evolve into a sustainable think tank after the end of the project, developing services to encourage the uptake of citizen science by policy-makers and practitioners. The sustainability plan describes the main services to be provided and an analysis of possible revenue streams from both the public and private sectors.

description: This talk will examine the implications of the COVID-19 pandemic for health inequalities. It outlines historical and contemporary evidence of inequalities in pandemics – drawing on international research into the Spanish flu pandemic of 1918, the H1N1 outbreak of 2009, and the recent international estimates of socio-economic, ethnic and geographical inequalities in COVID-19. It then examines how these inequalities in COVID-19 are related to existing inequalities in chronic diseases and the social determinants of health, arguing that we are experiencing a syndemic pandemic. It then explores the potential health consequences of the COVID-19 economic crisis. The talk concludes by reflecting on the longer term measures needed to ‘build back better’ and ensure that the COVID-19 pandemic does not increase health inequalities for future generations.

description: Complex Organic Molecules (COMs) have been detected in the interstellar medium (ISM). However, it is not clear whether their synthesis occurs on the icy surfaces of interstellar grains or via a series of gas-phase reactions. As a test case of the COMs synthesis in the ISM, we present new quantum chemical calculations on the formation of acetaldehyde (CH3CHO) from the coupling of the HCO and CH3 radicals, both in gas phase and on water ice surfaces. The binding energies of HCO and CH3 on the amorphous water ice were also computed (2333 and 734 K, respectively). Results indicate that, in gas phase, the products could be either CH3CHO, CH4 + CO, or CH3OCH, depending on the relative orientation of the two radicals. However, on the amorphous water ice, only the CH4 + CO product is possible due to the geometrical constraints imposed by the water ice surface. Therefore, acetaldehyde cannot be synthesized by the CH3 + HCO coupling on the icy grains. We discuss the implications of these results and other cases, such as ethylene glycol and dimethyl ether, in which similar situations can occur, suggesting that formation of these molecules on the grain surfaces might be unlikely.

description: The research of effective and reliable detrending methods for Spitzer data is of paramount importance for the characterization of exoplanetary atmospheres. To date, the totality of exoplanetary observations in the mid- and far-infrared, at wavelengths $>$3 $μ$m, have been taken with Spitzer. In some cases, in the past years, repeated observations and multiple reanalyses of the same datasets led to discrepant results, raising questions about the accuracy and reproducibility of such measurements. Morello et al. 2014, 2015 proposed a blind-source separation method based on the Independent Component Analysis of pixel time series (pixel-ICA) to analyze IRAC data, obtaining coherent results when applied to repeated transit observations previously debated in the literature. Here we introduce a variant to pixel-ICA through the use of wavelet transform, wavelet pixel-ICA, which extends its applicability to low-S/N cases. We describe the method and discuss the results obtained over twelve eclipses of the exoplanet XO3b observed during the "Warm Spitzer" era in the 4.5 $μ$m band. The final results will be reported also in Ingalls et al. (in prep.), together with results obtained with other detrending methods, and over ten synthetic eclipses that were analyzed for the "IRAC Data Challenge 2015". Our results are consistent within 1 $σ$ with the ones reported in Wong et al. 2014. The self-consistency of individual measurements of eclipse depth and phase curve slope over a span of more than three years proves the stability of Warm Spitzer/IRAC photometry within the error bars, at the level of 1 part in 10$^4$ in stellar flux.

These effects could even be enhanced, if government begins to acknowledge the value of these industries and incorporates their firms more strongly into its economic vision and strategy papers – export-orientation, stimulating local manufacturing and knowledge-intensive companies are all targets of Namibia’ s “Vision 2030”, targets that industries like fashion design and filmmaking already meet today.

description: We refine and analytically prove an old proposition due to Calabi and Markus on the shape of timelike geodesics of anti--de Sitter space in the ambient flat space. We prove that each timelike geodesic forms in the ambient space a circle of the radius determined by $Λ$, lying on a Euclidean two--plane. Then we outline an alternative proof for $AdS_4$. We also make a comment on the shape of timelike geodesics in de Sitter space.

description: Aus Anlass einer kürzlich vorgestellten internationalen Studie, die politisch links eingestellten Personen eine höhere Intoleranz attestierte, die sich aber nicht auf die Schweiz bezog, wird anhand einer schweizweiten Repräsentativbefragung unter Erwachsenen der Beziehung zwischen der Links-Rechts-Positionierung und verschiedenen Toleranz-massen nachgegangen. Dabei wird Toleranz differenziert betrachtet, einerseits als Duldung von verschiedenen Bevölkerungsgruppen und andererseits als Duldung verschiedener Meinungen. Die Ergebnisse zeigen erstens, dass eine «(eher) linke» politische Orientierung mit einer stärkeren Befürwortung verschiedener Bevölkerungsgruppen einer geht und insofern als toleranzsteigernd einzustufen ist. Zweitens zeigt sich, dass mit Blick auf bestimmte Meinungen tatsächlich eine höhere Toleranz auf Seiten politisch «(eher) rechts» eingestellter Befragter festzustellen ist: Diese sind signifikant häufiger der Ansicht, dass Kinder gezüchtigt und Straftaten entkriminalisiert werden sollten. Auf Basis dieser Befunde und zusätzlich präsentierter Auswertungen zur Demokratiezufriedenheit und zum Institutionenvertrauen wird letztlich gefolgert, dass politisch «links» eingestellte Personen teilweise intoleranter sind, und zwar Gruppen und Positionen gegenüber, die die demokratische, rechtsstaatliche Ordnung in Frage stellen.

description: Introduction. Suite à l’apparition du Sars-CoV-2, des mesures relatives aux risques épidémiques émergents ont été mises en place par l’ensemble des établissements de santé, entraînant des tensions d’approvisionnement en masques FFP2. L’objectif de cette étude réalisée pendant la crise sanitaire était d’évaluer la qualité des masques FFP2 reçus par le CHU de Nîmes avant leur utilisation. Matériel et méthode. Ces évaluations concernent la présence du marquage CE, la conformité aux normes relatives aux appareils de protection respiratoire (EN 149:2001+A1:2009) et la date limite d’utilisation. En complément, sont réalisés des contrôles visuels de l’intégrité du conditionnement, de la solidité des attaches et de l’aspect du masque. Son étanchéité est évaluée par le contrôle d’ajustement (Fit check) sur au moins trois testeurs ayant des morphologies faciales hétérogènes, complété par un test d’ajustement qualitatif (Fit test). Résultats. Les 50 masques testés respectent tous les normes attendues ou des normes équivalentes. Seuls 15 masques ont satisfait au test d’étanchéité. Aucun masque avec une plicature verticale conforme à la norme chinoise KN95 n’a réussi le test d’étanchéité. Conclusion. L’étanchéité des masques FFP2 doit systématiquement être contrôlée pour assurer une protection optimale des soignants. Les normes qualifient les capacités de filtration des masques mais pas leur étanchéité. La prévention du risque de transmission du Sars-CoV-2 ne se limite pas au port du masque, elle passe aussi par une protection oculaire, une hygiène des mains adaptée, une désinfection régulière des surfaces et un renouvellement fréquent de l’air.
Topological Protection from Random Rashba Spin-Orbit Backscattering: Ballistic Transport in a Helical Luttinger Liquid

description: The combination of Rashba spin-orbit coupling and potential disorder induces a random current operator for the edge states of a 2D topological insulator. We prove that charge transport through such an edge is ballistic at any temperature, with or without Luttinger liquid interactions. The solution exploits a mapping to a spin 1/2 in a time-dependent field that preserves the projection along one randomly undulating component (integrable dynamics). Our result is exact and rules out random Rashba backscattering as a source of temperature-dependent transport, absent integrability-breaking terms.

description: Pre-designed activities in a natural water setting, known as blue space interventions (BSIs), are recognized for their health-promoting qualities. BSIs, including those involving surfing, have been shown to provide opportunities for improving the self-efficacy of diverse groups, including people with substance use disorder (SUD). However, little is known about the lived experience of those in recovery from SUD or how BSIs contribute to self-efficacy and sustained recovery for this population. This research aimed to gain insight into the relationship between surfing, blue space, self-efficacy, and recovery-oriented health outcomes. Using a multi-method case study design with an autoethnographic lens, I utilized my own experience as an adult male experiencing SUD to explore whether participating in a self-managed BSI could influence my surfing and recovery efficacy. I developed a BSI, implemented it on myself, and reflected on my experience before, during, and after using various data collection tools, including: (a) a self-interview experience; (b) semi-structured reflective journal entries; (c) researcher-generated photographs; and (d) online semi-structured interviews with family members. This process required a great deal of learning, skill development, and discipline. Overcoming challenges associated with the BSI helped me uncover recovery-related skills (e.g., planning, preparation, social networking, introspection, self-regulation), pushed my reflective practices into a more well-developed and effective space, and encouraged the development of personal autonomy, which allowed me the opportunity to find value in my interpersonal relationships and connect purposefully with my spirituality. I believe that the opportunities and challenges associated with the intervention design and evaluation created an environment for my surfing and recovery efficacy to develop.

description: Phase coexistence phenomena have been intensively studied in strongly correlated materials where several ordered states simultaneously occur or compete. Material properties critically depend on external parameters and boundary conditions, where tiny changes result in qualitatively different ground states. However, up to date, phase coexistence phenomena have exclusively been reported for complex compounds composed of multiple elements. Here we show that charge- and magnetically ordered states coexist in double-layer Fe on Rh(001). Scanning tunneling microscopy and spectroscopy measurements reveal periodic charge order stripes below a temperature of 130 K. Close to liquid helium temperature, they are superimposed by ferromagnetic domains as observed by spin-polarized scanning tunneling microscopy. Temperature-dependent measurements reveal a pronounced cross-talk between charge and spin order at the ferromagnetic ordering temperature about 70 K, which is successfully modeled within an effective Landau theory including sixth-order terms. Our results show that subtle balance between structural modifications can lead to competing ordering phenomena.

description: Media coverage plays a crucial role in shaping public opinion. The way that migration is reported in the media can influence how people perceive and understand migration, and can also affect their attitudes towards migration and asylum, and the impact of media discourses on international refugee protection and asylum policies. We provide a comprehensive analysis of how the traditional and social media across selected European countries perceived and reported on migration and refugees from 2015 to 2022, during the period of the strongest waves of the so-called European migration crisis and the adoption of international agreements for their solution.

description: Software updates take an essential role in keeping IT environments secure. If service providers delay or do not install updates, it can cause unwanted security implications for their environments. This paper conducts a large-scale measurement study of the update behavior of websites and their utilized software stacks. Across 18 months, we analyze over 5.6M websites and 246 distinct client- and server-side software distributions. We found that almost all analyzed sites use outdated software. To understand the possible security implications of outdated software, we analyze the potential vulnerabilities that affect the utilized software. We show that software components are getting older and more vulnerable because they are not updated. We find that 95 % of the analyzed websites use at least one product for which a vulnerability existed.

description: Supervoxel segmentation has strong potential to be incorporated into early video analysis as superpixel segmentation has in image analysis. However, there are many plausible supervoxel methods and little understanding as to when and where each is most appropriate. Indeed, we are not aware of a single comparative study on supervoxel segmentation. To that end, we study seven supervoxel algorithms, including both off-line and streaming methods, in the context of what we consider to be a good supervoxel: namely, spatiotemporal uniformity, object/region boundary detection, region compression and parsimony. For the evaluation we propose a comprehensive suite of seven quality metrics to measure these desirable supervoxel characteristics. In addition, we evaluate the methods in a supervoxel classification task as a proxy for subsequent high-level uses of the supervoxels in video analysis. We use six existing benchmark video datasets with a variety of content-types and dense human annotations. Our findings have led us to conclusive evidence that the hierarchical graph-based (GBH), segmentation by weighted aggregation (SWA) and temporal superpixels (TSP) methods are the top-performers among the seven methods. They all perform well in terms of segmentation accuracy, but vary in regard to the other desiderata: GBH captures object boundaries best; SWA has the best potential for region compression; and TSP achieves the best undersegmentation error.
