description: Pulsar timing arrays are one of the powerful tools to test the existence of cosmic strings through searching for the gravitational wave background. The amplitude of the background connects to information on cosmic strings such as the tension and string network properties. In addition, one may be able to extract more information on properties of cosmic strings by measuring anisotropies in the gravitational wave (GW) background. In this paper, we provide estimates of the level of anisotropy expected in the GW background generated by cusps on cosmic strings. We find that the anisotropy level strongly depends on the initial loop size $α$, and thus we may be able to put constraint on $α$ by measuring the anisotropy of the GW background. We also find that certain regions of the parameter space can be probed by shifting the observation frequency of GWs.

description: Der Meeresspiegelanstieg ist eine physikalische Konsequenz des globalen Klimawandels. Hierdurch kommt es unweigerlich zum Verlust von Festland und zur Veränderung der Küstenlinien. Diese Studie bewertet die Folgen des Georisikos „Meeresspiegelanstieg“ für die nationale und internationale Sicherheit sowie dessen Potenzial, Migration zur verursachen, Konflikte zu initiieren oder bestehende zu verstärken. Neben einer globalen Betrachtung werden exemplarisch zwei unterschiedlich resiliente, intensiv landwirtschaftlich genutzte Deltaregionen (Rhein-Maas-Delta und Nildelta) sowie zwei Megastädte (Lagos und London) gegenübergestellt.
description: The rise of sea levels is a physical consequence of global climate change. It inevitably leads to the loss of dry land and changes in the coastlines. This study evaluates the consequences of the geological risk of the “rise of sea levels” for national and international security as well as its potential to cause migration and initiate or increase conflicts. In addition to a global examination, the study also compares two delta regions with a different resilience and intensive agricultural use (Rhine-Meuse Delta and the Nile Delta) as well as two megacities (Lagos and London).

description: We derive a necessary condition for the existence of marginally stable circular orbits of test particles in stationary axisymmetric spacetimes which possess a refection symmetry with respect to the equatorial plane; photon orbits are also addressed. Energy and angular momentum are shown to decouple from metric quantities, rendering a purely geometric characterization of circular orbits for this general class of metrics. The subsequent system is analyzed using resultants, providing an algorithmic approach for finding MSCO conditions. MSCOs are explicitly calculated for concrete examples of physical interest.

description: The decohering environment of a quantum bit is often described by the coupling to a large bath of spins. The quantum bit itself can be seen as a spin $S=1/2$ which is commonly called the central spin. The resulting central spin model describes an important mechanism of decoherence. We provide mathematically rigorous bounds for a persisting magnetization of the central spin in this model with and without magnetic field. In particular, we show that there is a well defined limit of infinite number of bath spins. Only if the fraction of very weakly coupled bath spins tends to 100\% does no magnetization persist.

description: In this paper, we investigate the generalised monogamy inequalities of convex-roof extended negativity (CREN) in multi-level systems. The generalised monogamy inequalities provide the upper and lower bounds of bipartite entanglement, which are obtained by using CREN and the CREN of assistance (CRENOA). Furthermore, we show that the CREN of multi-qubit pure states satisfies some monogamy relations. Additionally, we test the generalised monogamy inequalities for qudits by considering the partially coherent superposition of a generalised W-class state in a vacuum and show that the generalised monogamy inequalities are satisfied in this case as well.

description: A projective manifold is algebraically hyperbolic if the degree of any curve is bounded from above by its genus times a constant, which is independent from the curve. This is a property which follows from Kobayashi hyperbolicity. We prove that hyperkahler manifolds are non algebraically hyperbolic when the Picard rank is at least 3, or if the Picard rank is 2 and the SYZ conjecture on existence of Lagrangian fibrations is true. We also prove that if the automorphism group of a hyperkahler manifold is infinite then it is algebraically non-hyperbolic.

description: To form coherent multisensory perceptual representations, the brain must solve a causal inference problem: to decide if two sensory cues originated from the same event and should be combined, or if they came from different events and should be processed independently. According to current models of multisensory integration, during this process, the integrated (common cause) and segregated (different causes) internal perceptual models are entertained. In the present study, we propose that the causal inference process involves competition between these alternative perceptual models that engages the brain mechanisms of conflict processing. To test this hypothesis, we conducted two experiments, measuring reaction times (RTs) and electroencephalography, using an audiovisual ventriloquist illusion paradigm with varying degrees of intersensory disparities. Consistent with our hypotheses, incongruent trials led to slower RTs and higher fronto-medial theta power, both indicative of conflict. We also predicted that intermediate disparities would yield slower RTs and higher theta power when compared to congruent stimuli and to large disparities, owing to the steeper competition between causal models. Although this prediction was only validated in the RT study, both experiments displayed the anticipated trend. In conclusion, our findings suggest a potential involvement of the conflict mechanisms in multisensory integration of spatial information.This article is part of the theme issue ‘How the brain controls decision making in a multisensory world’.
title: Neural plasticity induced by different degrees of perturbation in auditory and visual sensory systems
Creators: name: Federici, Alessandra Enrica Chiara
Publisher: name: IMT Alti Studi Lucca
Year: 2022

description: Visual or auditory sensory deprivation represents a key model for studying experience-dependent plasticity. Different types of deprivations (congenital-late, temporary-permanent, peripheral-central)are characterized by a certain degree of perturbation of the typical sensory experience and can be represented in a three-dimensional space showing the distance from the typical experience. The dimensions are:(i) when the deprivation occurs, (ii) how long the deprivation lasts, and (iii) where is the barrier that causes the deprivation. Each dimension can be responsible for a low, medium, or high degree of perturbation. In thisdissertation, visual and auditory deprivation models are employed to investigate unisensory and multisensory neural plasticity. The first study (low degree of perturbation) aimed to unveil whether short-term monocular deprivation in the adult brain can induce neural plasticity beyond the visual system. The second study (medium degree of perturbation), using the model of temporary deprivation, assessed whether neural tracking of speech envelope could develop even in the absence of auditory stimulation from birth. Finally, the third study (high degree of perturbation) investigated how cerebral visual impairment affects visuospatial processing. Neural oscillations were used as windows to investigate plasticity mechanisms; time-frequency analysis was employed when short stimuli were presented, and neural tracking when the stimuli were continuous. Results revealed that even a low degree of sensory perturbation induces plasticity that extends beyond the deprived modality (study 1); altered neural tracking develops following a medium degree perturbation (study 2); a high degree of perturbation has a widespread impact on neural activity (study 3). These results strengthen evidence of the pivotal role of sensory experience revealing multifaced aspects of experience-dependent plasticity. Modeling the degree of perturbation could be a helpful perspective for a deeper understanding of how neural dynamics are affected by different types of deprivation and for shedding light on ranges of flexibility in neural processing with potential clinical implications.

We show that they behave in an analogous way to how strong Morita equivalence does for the category of C*-algebras. In particular, we prove that strong $Δ$-equivalence coincides with stable isomorphism under the expected countability hypothesis, and that strongly TRO equivalent operator spaces admit a correspondence between particular representations. Furthermore we show that strongly $Δ$-equivalent operator spaces have stably isomorphic second duals and strongly $Δ$-equivalent TRO envelopes. In the case of unital operator spaces, strong $Δ$-equivalence implies stable isomorphism of the C*-envelopes.

description: The hardest audience for university museums to engage is often the one closest at hand – university students. There is much competition for the time of our 50,000 students. Most work, at least part time, and they live in a large urban area. Studies show that most have not regularly attended a museum before they enter university. Our attendance is 150,000 annually; our mission is to educate all students, not just those studying art or related disciplines. Ways to engage students include collaborating with student organizations; engaging faculty from diverse disciplines to make assignments and hold classes in the museum; inviting students to social events (such as dances for new students to meet each other) that also involve looking at art; collaborating with unlikely departments (such as chemical engineering and materials sciences) to sponsor lectures (on topics such as elegance in the arts and sciences) and other programs; and offering cash prizes for student essays about art on display. While our initial success might have been the attraction of our new Frank Gehry designed facility (1993) continued success involves programs. My paper will describe ways for university museums to widen student audiences, particularly from non-art students.
description: O publico mais dificil de conquistar para um museu universitario é, por vezes, aquele que se encontra mais proximo - os estudantes. Com efeito, o tempo dos 50.000 estudantes da Universidade do Minnesota é escasso: para além do estudo e das aulas, muitos ainda trabalham e vivem em grandes areas urbanas vizinhas. Para além disso, alguns estudos revelam que a maioria nâo é visitante habitual de museùs à entrada na universidade. O Museu de Arte Frederick R. Weisman é visitado anualmente por cerca de 150.000 estudantes e pretende atingir todos os estudantes e nâo apenas os de arte. Os seus programas educacionais incluem a colaboraçâo com organizaçôes e associaçôes de estudantes, a promoçâo de visitas e aulas das mais diversas disciplinas nas suas instalaçôes, o convite a estudantes para eventos sociais que passem igualmente por contemplar obras de arte, a colaboraçâo com departamentos a priori distantes (corno os de engenharia quìmica e de ciências dos materials) para a realizaçâo de conferências e outras actividades (sobre a elegância na arte e na ciancia, por exemplo) e ainda a oferta de prémios a estudos sobre arte desenvolvidos por estudantes. Apesar do êxito inicial do Museu se dever, sem duvida, ao magnìfico edifìcio concebido por Frank Gehry (1993), um sucesso sustentado passa necessariamente pelos programas e exposiçoes que este concebe e implementa. Este artigo descreve algumas iniciativas que um museu universitario de arte pode desenvolver no sentido de alargar o àmbito dos seu publico estudantil, em particular a estudantes que nao sâo de arte.

description: We investigate the effect of external magnetic fields on equilibration in the improved holographic QCD theory in the deconfined phase using the AdS/CFT correspondence. In particular we calculate the quasinormal mode spectra in the corresponding black brane solutions and study their dependence on temperature, momentum and magnetic field, both in the scalar and the shear channels. We find complex patterns in the motion of quasinormal modes on the complex plane, including certain cross overs between the lowest lying modes under varying magnetic field, momentum and temperature. We also discover a critical value of the magnetic field $B_c$ above which the hydrodynamic approximation breaks down, as the imaginary part of the first excited quasi-normal mode in the shear channel becomes smaller than that of the hydro mode.

description: Poster presented at the 8th Lancaster International Conference on Infant and Early Child Development (LCICD) 2023 Abstract: Mean length utterance (MLU) is a common measure of syntactic complexity in studies of parent-child interactions, children’s language development and in the diagnosis of children’s speech disorders. Since Brown (1973), MLU has been operationalised differently by different authors (e.g., morphemes or words; trying to identify the minimum viable amount of speech that needs to be transcribed). Much of the original research was conducted in monolingual English-speaking populations. These measures have been successfully adapted for use in other monolingual populations (e.g., Brazilian Portuguese: Nóro & Mota, 2019; Dutch: Vandewalle et al., 2012, etc.). However, applying these metrics in multilingual translanguaging populations is more complex. Some researchers exclude from computation all code-switched utterances (e.g., Bedore et al., 2010; Yow et al., 2017), which may systematically over- or underestimate the true complexity of multilingual speech. This paper explores measurement characteristics of MLU-like metrics in a large corpus of child-directed speech from multilingual Singapore (languages included in sample: English, Mandarin, Malay). Methods: Spontaneous child-directed speech was elicited using a wordless picture book (‘What A Scary Storm’, Styles, 2020) in the micro-longitudinal Talk Together Study (N = 146, over three timepoints; Woon et al., 2021). To test out different measurement parameters, a stratified subsample of twenty transcripts was selected (age: 10 to 34 months old). We compare nine MLU-like measures and discuss which measures show the best fit to the underlying structure of the subsample. Metrics were applied to morphemes to enable cross-linguistic comparison across typologically diverse languages. Results: The distribution of morphemes per utterance is non-normal, with many very-short utterances and few very-long utterances, hence mean length of utterance is a poor measure of central tendency. The underlying distribution is exGaussian: two parameters describe the length of a typical utterance (μ), and the characteristics of unusually long utterances (𝜏). In our preliminary investigations, both short utterances and unusually long utterances tend to increase in morpheme count with increasing age (μ-LU: ρ = 0.40; 𝜏-LU: ρ = 0.26, and the proportion of monomorphemic utterances decreases (ρ = -0.26), albeit underpowered in this small subsample. The full paper will report the measurement properties as applied to the full corpus of transcriptions at timepoint 1 (N = 146) to provide adequate power (G*Power: Faul, 2009). Conclusion: We present a decision tree as a reproducible, pre-registerable pathway for deciding which measurement of MLU-like syntactic complexity is best for data of different types.

description: We study the low-energy physics of a broad class of time-reversal invariant and SU(2)-symmetric one-dimensional spin-S systems in the presence of quenched disorder via a strong-disorder renormalization-group technique. We show that, in general, there is an antiferromagnetic phase with an emergent SU(2S+1) symmetry. The ground state of this phase is a random singlet state in which the singlets are formed by pairs of spins. For integer spins, there is an additional antiferromagnetic phase which does not exhibit any emergent symmetry (except for S=1). The corresponding ground state is a random singlet one but the singlets are formed mostly by trios of spins. In each case the corresponding low-energy dynamics is activated, i.e., with a formally infinite dynamical exponent, and related to distinct infinite-randomness fixed points. The phase diagram has two other phases with ferromagnetic tendencies: a disordered ferromagnetic phase and a large spin phase in which the effective disorder is asymptotically finite. In the latter case, the dynamical scaling is governed by a conventional power law with a finite dynamical exponent.

description: Let $Ω\subset\mathbb{R}^ν$, $ν\ge 2$, be a $C^{1,1}$ domain whose boundary $\partialΩ$ is either compact or behaves suitably at infinity. For $p\in(1,\infty)$ and $α>0$, define \[ Λ(Ω,p,α):=\inf_{\substack{u\in W^{1,p}(Ω)\\ u\not\equiv 0}}\dfrac{\displaystyle \int_Ω|\nabla u|^p \mathrm{d} x - α\displaystyle\int_{\partialΩ} |u|^p\mathrm{d}σ}{\displaystyle\int_Ω|u|^p\mathrm{d} x}, \] where $\mathrm{d}σ$ is the surface measure on $\partialΩ$. We show the asymptotics \[ Λ(Ω,p,α)=-(p-1)α^{\frac{p}{p-1}} - (ν-1)H_\mathrm{max}\, α+ o(α), \quad α\to+\infty, \] where $H_\mathrm{max}$ is the maximum mean curvature of $\partialΩ$. The asymptotic behavior of the associated minimizers is discussed as well. The estimate is then applied to the study of the best constant in a boundary trace theorem for expanding domains, to the norm estimate for extension operators and to related isoperimetric inequalities.

Boosting Community Engagement: the Open Science Community Incubator Program (Skills4EOSC)

description: The transition to Open Science is in essence a culture change movement, which is why community engagement is critical for the transition to take shape. In particular, local grass-roots Open Science Communities (OSCs), such as those united in the ‘International Network of Open Science Communities’ (INOSC), have demonstrated to be drivers of change. In an OSC, researchers get together to share knowledge and best-practices, thereby increasing the awareness and facilitating the adoption of OS practice. By the same token, OSCs interact with local and (inter)national stakeholders to provide input to policies, services and infrastructure related to OS, shaping the transition to OS in accordance with researchers’ needs and perspectives. In recent year, there has been a rapid increase in the number of and size of OSCs, with over 20 communities active in 12 countries, where well over 2500 researchers get together to put OS to practice. However, setting-up and managing an OSC a challenge and requires specific skills and efforts. It is therefore that the European project ‘Skills4EOSC’ is collaborating with INOSC to provide a 12-week online onboarding program for new OSCs: the OSC Incubator Program. Over the course of six modules, participants work towards launching a ‘Minimum Viable OSC’ and prepare to foster and maintain their community with an ‘OSC Master Plan’, which consists of plans for community identity, community engagement, communication, stakeholder engagement, monitoring and sustainability. The program targets researchers and research supporters – both are well suited to start a local OSC. In this lightning talk, we introduce the OSC Incubator Program and invite colleagues around the globe to partake in the program and set-up their own OSC. The OSC Incubator program is free of charge and is offered twice per year and there is room for up-to 10 participants per cohort.

description: Unknown quantum information cannot be perfectly copied (cloned). This statement is the bedrock of quantum technologies and quantum cryptography, including the seminal scheme of Wiesner's quantum money, which was the first quantum-cryptographic proposal. Surprisingly, to our knowledge, quantum money has not been tested experimentally yet. Here, we experimentally revisit the Wiesner idea, assuming a banknote to be an image encoded in the polarization states of single photons. We demonstrate that it is possible to use quantum states to prepare a banknote that cannot be ideally copied without making the owner aware of only unauthorized actions. We provide the security conditions for quantum money by investigating the physically-achievable limits on the fidelity of 1-to-2 copying of arbitrary sequences of qubits. These results can be applied as a security measure in quantum digital right management.

We show that different visual representation of the reject/accept option have a significant impact on users’ decision.We also found that the labeling of the reject option has a significant impact. In addition, we confirm previous research regarding biasing text (which has no significant impact on users’ decision). Our results on users’ attitude towards cookie disclaimers indicate that for several user groups the design of the disclaimer only plays a secondary role when it comes to decision making. We provide recommendations on how to improve the situation for the different user groups.
The "Parity" Anomaly On An Unorientable Manifold

description: The "parity" anomaly -- more accurately described as an anomaly in time-reversal or reflection symmetry -- arises in certain theories of fermions coupled to gauge fields and/or gravity in a spacetime of odd dimension. This anomaly has traditionally been studied on orientable manifolds only, but recent developments involving topological superconductors have made it clear that one can get more information by asking what happens on an unorientable manifold. In this paper, we give a full description of the "parity" anomaly for fermions coupled to gauge fields and gravity in $2+1$ dimensions on a possibly unorientable spacetime. We consider an application to topological superconductors and another application to M-theory. The application to topological superconductors involves using knowledge of the "parity" anomaly as an ingredient in constructing gapped boundary states of these systems and in particular in gapping the boundary of a $ν=16$ system in a topologically trivial fashion. The application to M-theory involves showing the consistency of the path integral of an M-theory membrane on a possibly unorientable worldvolume. In the past, this has been done only in the orientable case.

description: This paper is about geometric quantization of the Hitchin system. We quantize a Kahler form on the Hitchin moduli space (which is half the first Kahler form defined by Hitchin) by considering the Quillen bundle as the prequantum line bundle and modifying the Quillen metric using the Higgs field so that the curvature is proportional to the Kahler form. We show that this Kahler form is integral and the Quillen bundle descends as a prequantum line bundle on the moduli space. It is holomorphic and hence one can take holomorphic square integrable sections as the Hilbert space of quantization of the Hitchin moduli space.

description: We perform first-principles band structure calculations for the tetragonal and monoclinic structures of LaO$_{0.5}$F$_{0.5}$BiS$_2$. We find that the Bi $6p_{x,y}$ bands on two BiS$_2$ layers exhibit a sizable splitting at the X = ($π$, 0, 0) and several other \textbf{k}-points for the monoclinic structure. We show that this feature originates from the inter-BiS$_2$ layer coupling strongly enhanced by the symmetry breaking of the crystal structure. The Fermi surface also shows a large splitting and becomes anisotropic with respect to the $k_x$ and $k_y$ directions in the monoclinic structure, whereas it remains almost flat with respect to the $k_z$ direction.

description: A consistent and unified picture for critical phenomena of charged AdS black holes in $f(R)$ gravity is drawn in this paper. Firstly, we investigate the phase transition in canonical ensemble. We derive the explicit solutions corresponding to the divergence of $C_Q$. The two solutions merge into one when the condition $Q_c=\sqrt{\frac{-1}{3R_0}}$ is satisfied. The curve of specific heat for $QQ_c$, the specific heat is always positive, implying the black holes are locally stable and no phase transition will take place. Secondly, both the $T-r_+$ curve and $T-S$ curve $f(R)$ AdS black holes are investigated and they exhibit Van der Vaals like behavior as the $P-v$ curve in the former research. Critical physical quantities are obtained and they are consistent with those derived from the specific heat analysis. We carry out numerical check of Maxwell equal area law for the cases $Q=0.2Q_c, 0.4Q_c, 0.6Q_c, 0.8Q_c$. The relative errors are amazingly small and can be negligible. So the Maxwell equal area law holds for $T-S$ curve of $f(R)$ black holes. Thirdly, we establish geometrothermodynamics for $f(R)$ AdS black hole to examine the phase structure. It is shown that the Legendre invariant scalar curvature $\mathfrak{R}$ would diverge exactly where the specific heat diverges. To summarize, the above three perspectives are consistent with each other, thus providing a unified picture which deepens the understanding of critical phenomena of $f(R)$ AdS black holes.

nature positive economy

description: Poorly planned urbanisation can lead to societal challenges as social deprivation, climate change, deteriorating health and increasing pressure on urban nature. Urban ecosystem restoration can contribute to lessen these challenges, e.g. through implementing nature-based solutions (NBS). This presentation was made as part of the online webinar ‘Sustaining cities, Naturally: Urban ecosystem restoration in Europe, China and Latin America’, which took place as an official side-event of the European Week of Regions and Cities 2022 on 13th and 14th October 2023. The webinar was jointly organised by the projects: INTERLACE, CONEXUS, Regreen and CLEARING HOUSE. The webinar illustrated how Horizon 2020 projects support international cooperation in knowledge creation and knowledge exchange between local authorities and researchers to promote urban ecosystem restoration in Europe, China and Latin America and brought together cities, regions and local authorities, city network representatives, policy makers, researchers, civil society and experts on nature-based solutions and urban ecosystem restoration from Europe, China and Latin America.

Revisiting Stochastic Variability of AGNs with Structure Functions

description: Discrepancies between reported structure function (SF) slopes and their overall flatness as compared to expectations from the damped random walk (DRW) model, which generally well describes the variability of active galactic nuclei (AGNs), have triggered us to study this problem in detail. We review common AGN variability observables and identify their most common problems. Equipped with this knowledge, we study ~9000 r-band AGN light curves from Stripe 82 of the Sloan Digital Sky Survey, using SFs described by stochastic processes with the power exponential covariance matrix of the signal. We model the "subensemble" SFs in the redshift-absolute magnitude bins with the full SF equation (including the turnover and the noise part) and a single power law (SPL; in the "red noise regime" after subtracting the noise term). The distribution of full-equation SF (SPL) slopes peaks at gamma = 0.55 +/- 0.08 (0.52 +/- 0.06) and is consistent with the DRW model. There is a hint of a weak correlation of gamma with the luminosity and a lack of correlation with the black hole mass. The typical decorrelation timescale in the optical is tau = 0.97 +/- 0.46 year. The SF amplitude at one year obtained from the SPL fitting is SF_0 = 0.22 +/- 0.06 mag and is overestimated because the SF is already at the turnover part, so the true value is SF_0 = 0.20 +/- 0.06 mag. The asymptotic variability is SF_\infty = 0.25 +/- 0.06 mag. It is strongly anticorrelated with both the luminosity and the Eddington ratio and is correlated with the black hole mass. The reliability of these results is fortified with Monte Carlo simulations.

description: In this paper we propose a scale invariant search strategy for hadronic top or bottom plus missing energy final states. We present a method which shows flat efficiencies and background rejection factors over broad ranges of parameters and masses. The resulting search can be easily recast into a limit on alternative models. We show the strength of the method in a natural SUSY setup where stop and sbottom squarks are pair produced and decay into hadronically decaying top quarks or bottom quarks and higgsinos.

description: For the case of spin zero we construct conjugate pairs of operators on Fock space. On states multiplied by polarization vectors coordinate operators Q conjugate to the momentum operator P exist. The massive case is derived from a geometrical quantity, the massless case is realized by taking the limit mass going to zero on the one hand, on the other from conformal transformations. Crucial is the norm problem of the states on which the Q's act: they determine eventually how many independent conjugate pairs exist. It is intriguing that light wedge variables and hence the wedge-local case seems to be preferred.
