description: We study an unsteady non linear fluid-structure interaction problem which is a simplified model to describe blood flow through viscoleastic arteries. We consider a Newtonian incompressible two-dimensional flow described by the Navier-Stokes equations set in an unknown domain depending on the displacement of a structure, which itself satisfies a linear viscoelastic beam equation. The fluid and the structure are fully coupled via interface conditions prescribing the continuity of the velocities at the fluid-structure interface and the action-reaction principle. We prove that strong solutions to this problem are global-in-time. We obtain in particular that contact between the viscoleastic wall and the bottom of the fluid cavity does not occur in finite time. To our knowledge, this is the first occurrence of a no-contact result, but also of existence of strong solutions globally in time, in the frame of interactions between a viscous fluid and a deformable structure.

The Smith Normal Form Distribution of a Random Integer Matrix

description: We show that the density $μ$ of the Smith normal form (SNF) of a random integer matrix exists and equals a product of densities $μ_{p^s}$ of SNF over $\mathbb{Z}/p^s\mathbb{Z}$ with $p$ a prime and $s$ some positive integer. Our approach is to connect the SNF of a matrix with the greatest common divisors (gcds) of certain polynomials of matrix entries, and develop the theory of multi-gcd distribution of polynomial values at a random integer vector. We also derive a formula for $μ_{p^s}$ and compute the density $μ$ for several interesting types of sets. Finally, we determine the maximum and minimum of $μ_{p^s}$ and establish its monotonicity properties and limiting behaviors.
title: Virgo to virago: Medea in the silver age
Creators: name: Corrigan, Kirsty Helen
Publisher: name: University of Kent
Year: 2022

description: The infamous mythological figure of Medea appears in the extant texts of three Silver Age Latin authors: Ovid (principally in the epic Metamorphoses and elegiac epistles Heroides, but also minor references in his other elegiac poetry), Seneca (the tragedy Medea), and Valerius Flaccus (the epic Argonautica). Although each author approaches the character differently, similarities can be found in their treatments. Through a detailed character study of Medea in these texts we are able to discern that, as well as being a character full of ambiguities, she is always portrayed with some measure of sympathy. This varies according to context, both of genre and of the particular stage of her myth being depicted: a large span of Medea’s life and actions is covered in these accounts, from innocent girl through to formidable sorceress. This sympathy occurs despite Medea being a notorious witch and murderess, whose wicked actions were an irresistible draw for the writers. This is especially remarkable since, in these works, she is a product of the Silver Age, and therefore these portrayals satisfy the gruesome and macabre taste of the period, for which Medea the sorceress was an especially suitable topic. This sympathetic view can, in part, be explained by the apparent admiration which the authors felt for her, although the favour of the age for rhetorical argument also contributes to this. Earlier predecessors also had important influences on these works: notably Euripides, Apollonius of Rhodes, and Virgil. There are elements of both victim and villain in these accounts, a typical ambiguous tension in her character, but Medea is foremost a remarkable figure deserving the attention she receives. Her fascination and appeal cannot be denied, since she emerges predominant in each account, eclipsing her counterpart hero Jason: therefore she should, perhaps, be considered the true hero of these texts.
I ‘numeri’ delle comiche italiane del Settecento. Primi appunti

description: Preamble and stimulus to more systematic investigations, the paper proposes an initial review of the actresses demography in Italy in the 18th century. Beyond its significant quantitative impact, the female component is significant above all because it attests the persistence of that mixture of different performative languages which is the distinctive feature of the Commedia dell’Arte, and that – not yet overwhelmed by the sectoral progress of professional skills –, is still visible in the 18th century. From a preliminary anagraphic survey, and through the sieve of exemplary events (like that of many actresses, as the Medebach and Marliani, Passalacqua and Rosina Costa, Teresa Gandini; Maria Donati, Antonia D’Arbes, Teodora Ricci and her sisters, Faustina Tesi), it emerges clearly the phenomenon of actresses who build their professionalism even as acrobats, dancers, singers and even businesswomen: this phenomenon is a particularly eloquent, when compared to a historical and legal context in which the capacity deficit (that excluded women from the public sphere and from holding officia and munera) had the full force of law and in which the status of ‘owner’ collided with that of minus habens. In short, new legal and artistic identities are asserting on the Italian scene of 18th century.

description: High comorbidity among pediatric disorders characterized by behavioral and emotional dysregulation poses problems for diagnosis and treatment, and suggests that these disorders may be better conceptualized as dimensions of abnormal behaviors. Furthermore, identifying neuroimaging biomarkers related to dimensional measures of behavior may provide targets to guide individualized treatment. We aimed to use functional neuroimaging and pattern regression techniques to determine whether patterns of brain activity could accurately decode individual-level severity on a dimensional scale measuring behavioural and emotional dysregulation at two different time points.

description: Symmetry-protected topological (SPT) phases are many-body quantum states that are topologically nontrivial as long as the relevant symmetries are unbroken. In this work we show that SPT phases are also well defined for average symmetries, where quenched disorders locally break the symmetries, but restore the symmetries upon disorder averaging. An example would be crystalline SPT phases with imperfect lattices. Specifically, we define the notion of average SPT for disordered ensembles of quantum states. We then classify and characterize a large class of average SPT phases using a decorated domain wall approach, in which domain walls (and more general defects) of the average symmetries are decorated with lower dimensional topological states. We then show that if the decorated domain walls have dimension higher than $(0+1)d$, then the boundary states of such average SPT will almost certainly be long-range entangled, with probability approaching $1$ as the system size approaches infinity. This generalizes the notion of t'Hooft anomaly to average symmetries, which we dub "average anomaly". The average anomaly can also manifest as constraints on lattice systems similar to the Lieb-Schultz-Mattis (LSM) theorems, but with only average lattice symmetries. We also generalize our problem to "quantum disorders" that can admit short-range entanglement on their own, and develop a theory of such generalized average SPTs purely based on density matrices and quantum channels. Our results indicate that topological quantum phenomena associated with average symmetries can be at least as rich as those with ordinary exact symmetries.

An interface and geometry preserving phase-field method for fully Eulerian fluid-structure interaction

description: We present an interface and geometry preserving (IGP) method for the modeling of fully Eulerian fluid-structure interaction via phase-field formulation. While the hyperbolic tangent interface profile is preserved by the time-dependent mobility model, the proposed method maintains the geometry of the solid-fluid interface by reducing the volume-conserved mean curvature flow. To achieve the reduction in the curvature flow, we construct a gradient-minimizing velocity field (GMV) for the convection of the order parameter. The constructed velocity field enables the preservation of the solid velocity in the solid domain while extending the velocity in the normal direction throughout the diffuse interface region. With this treatment, the GMV reduces the normal velocity difference of the level sets of the order parameter which alleviates the undesired thickening or thinning of the diffuse interface region due to the convection. During this process, the time-dependent mobility coefficient is substantially reduced and there is a lesser curvature flow. The GMV ensures that the diffuse interface region moves with the solid bulk such that the fluid-solid interface conforms to the geometry of the solid. Using the unified momentum equation and the phase-dependent interpolation, we integrate the IGP method into a fully Eulerian variational FSI solver based on the incompressible viscous fluid and the neo-Hookean solid. We first demonstrate the ability of the phase-field-based IGP method for the convection of circular and square interfaces with a prescribed velocity field. The variational FSI framework with the IGP method is then examined for the flow passing a fixed deformable block in a channel domain. Finally, the vibration of a plate attached behind a stationary cylinder subjected to incoming flow is employed to assess the fully Eulerian framework for a large aspect ratio and sharp corners.

description: To improve mathematical models of epidemics it is essential to move beyond the traditional assumption of homogeneous well--mixed population and involve more precise information on the network of contacts and transport links by which a stochastic process of the epidemics spreads. In general, the number of states of the network grows exponentially with its size, and a master equation description suffers from the curse of dimensionality. Almost all methods widely used in practice are versions of the stochastic simulation algorithm (SSA), which is notoriously known for its slow convergence. In this paper we numerically solve the chemical master equation for an SIR model on a general network using recently proposed tensor product algorithms. In numerical experiments we show that tensor product algorithms converge much faster than SSA and deliver more accurate results, which becomes particularly important for uncovering the probabilities of rare events, e.g. for number of infected people to exceed a (high) threshold.

Herausgearbeitet wird, warum es sich bei den verwendeten Apparaten wie dem Teleskop nicht etwa um ein ‚bloßes Instrumentarium‘, sondern vielmehr um Medien handelt, die sich in die resultierenden Bilder einschreiben. Weshalb diese Bilder neben Sichtbarkeiten stets auch Unsichtbarkeiten produzieren und keine mimetischen Abbildungen, sondern genuin hybride Bilder darstellen, wird im Anschluss erläutert. Für das Verständnis dieser Bilder ist eine genaue Kenntnis der technischen Grundlagen und Funktionsweisen astronomischer Apparate notwendig.

description: We previously reported that ceramide synthase 6 (CerS6) is elevated in response to folate stress in cancer cells, leading to enhanced production of C16-ceramide and apoptosis. Antifolate methotrexate (MTX), a drug commonly used in chemotherapy of several types of cancer, is a strong inhibitor of folate metabolism. Here we investigated whether this drug targets CerS6. We observed that CerS6 protein was markedly elevated in several cancer cell lines treated with MTX. In agreement with the enzyme elevation, its product C16-ceramide was also strongly elevated, so as several other ceramide species. The increase in C16-ceramide, however, was eliminated in MTX-treated cells lacking CerS6 through siRNA silencing, while the increase in other ceramides sustained. Furthermore, the siRNA silencing of CerS6 robustly protected A549 lung adenocarcinoma cells from MTX toxicity, while the silencing of another ceramide synthase, CerS4, which was also responsive to folate stress in our previous study, did not interfere with the MTX effect. The rescue effect of CerS6 silencing upon MTX treatment was further confirmed in HCT116 and HepG2 cell lines. Interestingly, CerS6 itself, but not CerS4, induced strong antiproliferative effect in several cancer cell lines if elevated by transient transfection. The effect of MTX on CerS6 elevation was likely p53 dependent, which is in agreement with the hypothesis that the protein is a transcriptional target of p53. In line with this notion, lometrexol, the antifolate inducing cytotoxicity through the p53-independent mechanism, did not affect CerS6 levels. We have also found that MTX induces the formation of ER aggregates, enriched with CerS6 protein. We further demonstrated that such aggregation requires CerS6 and suggests that it is an indication of ER stress. Overall, our study identified CerS6 and ceramide pathways as a novel MTX target.

description: The analysis of electromagnetic scattering in the isogeometric analysis (IGA) framework based on Loop subdivision has long been restricted to simply-connected geometries. The inability to analyze multiply-connected objects is a glaring omission. In this paper, we address this challenge. IGA provides seamless integration between the geometry and analysis by using the same basis set to represent both. In particular, IGA methods using subdivision basis sets exploit the fact that the basis functions used for surface description are smooth (with continuous second derivatives) almost everywhere. On simply-connected surfaces, this permits the definition of basis sets that are divergence-free and curl-free. What is missing from this suite is a basis set that is both divergence-free and curl-free, a necessary ingredient for a complete Helmholtz decomposition of currents on multiply-connected structures. In this paper, we effect this missing ingredient numerically using random polynomial vector fields. We show that this basis set is analytically divergence-free and curl-free. Furthermore, we show that these basis recovers curl-free, divergence-free, and curl-free and divergence-free fields. Finally, we use this basis set to discretize a well-conditioned integral equation for analyzing perfectly conducting objects and demonstrate excellent agreement with other methods.

description: That individuals attain socioeconomic status (SES) through their own effort and ability, which is a staple pillar of the meritocratic ethos and has been a popular topic of inquiry within social psychology. However, this focus on merit overshadowed other important causal factors that contribute to one’s SES, such as opportunity and chance. This study presents psychometrically validated scales measuring one’s causal beliefs of SES attainment for themselves (agency beliefs) and others (society beliefs). Utilizing a nationally representative sample, participants completed 68 items of causal agency and society beliefs for low and high SES attainment. Through factor analyses, item response theory, and careful item reduction, three subscales and six dimensions measuring (1) merit (effort and ability), (2) opportunity (social connections and privilege), and (3) chance (luck and fate) are introduced for each belief system. Correlation analyses reveal general support for construct validity. Implications and future directions are discussed.

description: We construct a novel class of spherically symmetric and asymptotically flat black holes and naked singularities surrounded by anisotropic dark matter fluid with the equation of state (EoS) of the form $P_t=ωρ$. We assume that dark matter is made of weakly interacting particles orbiting around the supermassive black hole in the galactic center and the dark matter halo is formed by means of Einstein clusters having only tangential pressure. In the large distance from the black hole, we obtain the constant flat curve with the upper bound for the dark matter state parameter $ω\lesssim 10^{-7}$. To this end, we also check the energy conditions of the dark matter fluid outside the black hole/naked singularity, the deflection of light by the galaxy, and the shadow images of the Sgr A$^\star$ black hole using the rotating and radiating particles. For the black hole case, we find that the effect of dark matter fluid on the shadow radius is small, in particular the angular radius of the black hole is shown to increase by the order $10^{-4} μ$arcsec compared to the vacuum solution. For the naked singularity we obtain significantly smaller shadow radius compared to the black hole case. Finally, we study the stability of the S2 star orbit around Sgr A$^\star$ black hole under dark matter effects. It is argued that the motion of S2 star orbit is stable for values $ω\lesssim 10^{-7}$, however further increase of $ω$ leads to unstable orbits. Using the observational result for the shadow images of the Sgr A$^\star$ reported by the EHT along with the tightest constraint for $ω$ found from the constant flat curve, we show that the black hole model is consistent with the data while the naked singularity in our model can be ruled out.

description: We stabilize an open cavity flow experiment to 1% of its original fluctuation level. For the first time, a multi-modal feedback control is automatically learned for this configuration. The key enabler is automatic in-situ optimization of control laws with machine learning augmented by a gradient descent algorithm, named gradient-enriched machine learning control (Cornejo Maceda et al. 2021, gMLC). gMLC is shown to learn one order of magnitude faster than MLC (Duriez et al. 2017, MLC). The physical interpretation of the feedback mechanism is assisted by a novel cluster-based control law visualization for flow dynamics and corresponding actuation commands. Starting point of the control experiment are two unforced open cavity benchmark configurations: a narrow-bandwidth regime with a single dominant frequency and a mode-switching regime where two frequencies compete. The feedback control commands the DBD actuator located at the leading edge. The flow is monitored by a downstream hot-wire sensor over the trailing edge. The feedback law is optimized with respect to the monitored fluctuation level. As reference, the self-oscillations of the mixing layer are mitigated with steady actuation. Then, a feedback controller is optimized with gMLC. As expected, feedback control outperforms steady actuation by achieving both, a better amplitude reduction and a significantly smaller actuation power, about about 1% of the actuation energy required for similarly effective steady forcing. Intriguingly, optimized laws learned for one regime performs well for the other untested regime as well. The proposed control strategy can be expected to be applicable for many other shear flow experiments.

description: There are no prospective studies of aggressive non-Hodgkin lymphoma (NHL) treated with CHOP in sub-Saharan Africa. We enrolled adults with aggressive NHL in Malawi between June 2013 and May 2015. Chemotherapy and supportive care were standardized, and HIV+ patients received antiretroviral therapy (ART). Thirty-seven of 58 patients (64%) were HIV+. Median age was 47 years (IQR 39–56), and 35 (60%) were male. Thirty-five patients (60%) had stage III/IV, 43 (74%) B symptoms, and 28 (48%) performance status ≥2. B-cell NHL predominated among HIV+ patients, and all T-cell NHL occurred among HIV- individuals. Thirty-one HIV+ patients (84%) were on ART for a median 9.9 months (IQR 1.1–31.7) before NHL diagnosis, median CD4 was 121 cells/μL (IQR 61–244), and 43% had suppressed HIV RNA. HIV+ patients received a similar number of CHOP cycles compared to HIV- patients, but more frequently developed grade 3/4 neutropenia (84% vs 31%, p = 0.001), resulting in modestly lower cyclophosphamide and doxorubicin doses with longer intervals between cycles. Twelve-month overall survival (OS) was 45% (95% CI 31–57%). T-cell NHL (HR 3.90, p = 0.017), hemoglobin (HR 0.82 per g/dL, p = 0.017), albumin (HR 0.57 per g/dL, p = 0.019), and IPI (HR 2.02 per unit, p<0.001) were associated with mortality. HIV was not associated with mortality, and findings were similar among patients with diffuse large B-cell lymphoma. Twenty-three deaths were from NHL (12 HIV+, 11 HIV-), and 12 from CHOP (9 HIV+, 3 HIV-). CHOP can be safe, effective, and feasible for aggressive NHL in Malawi with and without HIV.

description: Identity fusion is a visceral feeling of oneness with a group that predicts extreme pro-group behaviors. However, the effects of fusion depending on the nature of such behaviors -violent versus nonviolent- and the factors that may incline strongly fused individuals to display them still remain unexplored. To fill this gap, we performed two correlational studies in which we examined whether moral beliefs regarding the justifiability of violence moderate the relationship between fusion with the family (Study 1), or with the country (Study 2), and willingness to engage in violent and nonviolent pro-group acts. Results showed that strongly fused participants were more willing to act violently than weakly fused participants, but only when their beliefs in the moral justifiability of violence were high. In contrast, their willingness to engage in nonviolent acts was not influenced by moral beliefs.
Il mulo di Lessing
Creators: name: Perrelli, Franco
Publisher: name: Drammaturgia
Year: 2016

description: In Hamburg Dramaturgy, the lengthy parallel analysis that Lessing devoted to the tragedies of Maffei and Voltaire about the figure of Merope, led him to an Enlightenment re-reading of Aristotle and to an hypothetical reconstruction of Euripides’ Cresphontes. In this way, the German critic was able to underline Euripides’ attitude to a technique of preliminary revelation of the characters and the nodal points of the plot: on one side, it can reduce the suspense; on the other, it avoids the most superficial coups de théâtre, shifting the tragic effect from ‘what’ to ‘how’ it occurs. Contesting the position of Abbé d’Aubignac and supporting Diderot, Lessing realized that a considerable part of this Euripidean technique is based on the remixing of diegesis and dramatic mimesis: it is an uncommon ‘hybrid’ of genres that appears efficacious and extremely useful (just like the intersection from which is generated a mule). Lessing’s analysis had an important and documented influence on the modern theatre: here, we can find a Sophoclean approach (Ibsen) and an Euripidean approach to the drama. In particular, the Euripidean line is developed in Strindberg’s epic dramaturgy and, in all its evidence, in Brecht.

description: Machine learning models can be improved by adapting them to respect existing background knowledge. In this paper we consider multitask Gaussian processes, with background knowledge in the form of constraints that require a specific sum of the outputs to be constant. This is achieved by conditioning the prior distribution on the constraint fulfillment. The approach allows for both linear and nonlinear constraints. We demonstrate that the constraints are fulfilled with high precision and that the construction can improve the overall prediction accuracy as compared to the standard Gaussian process.

description: Drawing on the theory of planned behavior (TPB) and the volunteer process model (VPM), we compared proximal (the TPB variables) and distal (general social support and sense of community) antecedents and quality of experience between civic (CP) and political (PP) participation. Outcome variables were future intentions. We used data from a mail survey of 3,231 adults with or without prior CP or PP experience. Both inexperienced and experienced individuals perceived PP more negatively than CP. Quality of experience was also rated substantially more negatively for PP than for CP. Distal antecedents had similar effects for CP and PP, but they were mostly significant for CP only. In line with the VPM, quality of experience was the strongest predictor of future intentions in experienced individuals. Perceived behavioral control was the strongest mediator. Findings corroborate the distinction between CP and PP and suggest that PP is much less attractive on average.

description: Individual privacy accounting enables bounding differential privacy (DP) loss individually for each participant involved in the analysis. This can be informative as often the individual privacy losses are considerably smaller than those indicated by the DP bounds that are based on considering worst-case bounds at each data access. In order to account for the individual privacy losses in a principled manner, we need a privacy accountant for adaptive compositions of randomised mechanisms, where the loss incurred at a given data access is allowed to be smaller than the worst-case loss. This kind of analysis has been carried out for the Rényi differential privacy (RDP) by Feldman and Zrnic (2021), however not yet for the so-called optimal privacy accountants. We make first steps in this direction by providing a careful analysis using the Gaussian differential privacy which gives optimal bounds for the Gaussian mechanism, one of the most versatile DP mechanisms. This approach is based on determining a certain supermartingale for the hockey-stick divergence and on extending the Rényi divergence-based fully adaptive composition results by Feldman and Zrnic. We also consider measuring the individual $(\varepsilon,δ)$-privacy losses using the so-called privacy loss distributions. With the help of the Blackwell theorem, we can then make use of the RDP analysis to construct an approximative individual $(\varepsilon,δ)$-accountant.

description: Methamphetamine (MA) addiction is a growing epidemic worldwide. Chronic MA use has been shown to lead to neurotoxicity in rodents and humans. Magnetic resonance imaging (MRI) studies in MA users have shown enlarged striatal volumes and positron emission tomography (PET) studies have shown decreased brain glucose metabolism (BGluM) in the striatum of detoxified MA users. The present study examines structural changes of the brain, observes microglial activation, and assesses changes in brain function, in response to chronic MA treatment. Rats were randomly split into three distinct treatment groups and treated daily for four months, via i.p. injection, with saline (controls), or low dose (LD) MA (4 mg/kg), or high dose (HD) MA (8 mg/kg). Sixteen weeks into the treatment period, rats were injected with a glucose analog, [18F] fluorodeoxyglucose (FDG), and their brains were scanned with micro-PET to assess regional BGluM. At the end of MA treatment, magnetic resonance imaging at 21T was performed on perfused rats to determine regional brain volume and in vitro [3H]PK 11195 autoradiography was performed on fresh-frozen brain tissue to measure microglia activation. When compared with controls, chronic HD MA-treated rats had enlarged striatal volumes and increases in [3H]PK 11195 binding in striatum, the nucleus accumbens, frontal cortical areas, the rhinal cortices, and the cerebellar nuclei. FDG microPET imaging showed that LD MA-treated rats had higher BGluM in insular and somatosensory cortices, face sensory nucleus of the thalamus, and brainstem reticular formation, while HD MA-treated rats had higher BGluM in primary and higher order somatosensory and the retrosplenial cortices, compared with controls. HD and LD MA-treated rats had lower BGluM in the tail of the striatum, rhinal cortex, and subiculum and HD MA also had lower BGluM in hippocampus than controls. These results corroborate clinical findings and help further examine the mechanisms behind MA-induced neurotoxicity.

description: We present analysis of the light curves (LCs) of 77 hydrogen-poor superluminous supernovae (SLSNe-I) discovered during the Zwicky Transient Facility Phase-I operation. We find that the majority (67\%) of the sample can be fit equally well by both magnetar and ejecta-circumstellar medium (CSM) interaction plus $^{56}$Ni decay models. This implies that LCs alone can not unambiguously constrain the physical power sources for a SLSN-I. However, 23\% of the sample show inverted V-shape, steep declining LCs or features of long rise and fast post-peak decay, which are better described by the CSM+Ni model. The remaining 10\% of the sample favor the magnetar model. Moreover, our analysis shows that the LC undulations are quite common, with a fraction of $18-44\% $ in our gold sample. Among those strongly undulating events, about 62\% of them are found to be CSM-favored, implying that the undulations tend to occur in the CSM-favored events. Undulations show a wide range in energy and duration, with median values (and 1$σ$ errors) being as $1.7\%^{+1.5\%}_{-0.7\%}\,\rm E_{\rm rad,total}$ and $28.8^{+14.4}_{-9.1}$\,days, respectively. Our analysis of the undulation time scales suggests that intrinsic temporal variations of the central engine can explain half of the undulating events, while CSM interaction can account for the majority of the sample. Finally, all of the well-observed He-rich SLSNe-Ib have either strongly undulating LCs or the LCs are much better fit by the CSM+Ni model. These observations imply that their progenitor stars have not had enough time to lose all of the He-envelopes before supernova explosions, and H-poor CSM are likely to present in these events.

description: The article proposes a universal dual-axis intelligent systems assessment scale. The scale considers the properties of intelligent systems within the environmental context, which develops over time. In contrast to the frequent consideration of the 'mind' of artificial intelligent systems on a scale from 'weak' to 'strong', we highlight the modulating influences of anticipatory ability on their 'brute force'. In addition, the complexity, the 'weight' of the cognitive task and the ability to critically assess it beforehand determine the actual set of cognitive tools, the use of which provides the best result in these conditions. In fact, the presence of 'common sense' options is what connects the ability to solve a problem with the correct use of such an ability itself. The degree of 'correctness' and 'adequacy' is determined by the combination of a suitable solution with the temporal characteristics of the event, phenomenon, object or subject under study.
‘Co₂.’ Intervista a Giorgio Battistelli

description: On the 16th of June 2015, the premiere of the opera CO₂ by Giorgio Battistelli, based on a libretto by Ian Burton and directed by Robert Carsen, opened at the Teatro alla Scala, meeting with great acclaim from the critics and public. After a long period of preparatory work and many changes in the production, the opera coincided with EXPO 2015, addressing, as it does, environmental issues and deliberately broaching exceptionally topical issues in economic, social and political thinking. Highlighting a subject as urgent as the pollution of the Earth in an operatic setting achieved a double effect: it created an opera which functions as a means of reflection on contemporary reality – this is already evident in the title, a chemical formula repeated so often nowadays that it even appears in the recent papal encyclical – and produced sung theatre with no frills which is able to express a universal truth. These elements are at the heart of the opera’s originality: CO₂ can rightly be considered the opera of the New Millennium. During the conversation, which took place in Rome on the 30th of March 2015, Giorgio Battistelli talked with great enthusiasm about how important it is to make music theatre an expression of social commitment. When he speaks on this subject, you can perceive his close attention for the theatrical word, for the musicality of his work and for its ethical and ideological content which, however, never falls into the trap of rhetoric. The sincerity and character of the author shine through the interview, as do his writing methods, and in the generous and forthcoming dialogue we get a faithful picture of his painstaking creative process.

description: For the distinction of the Andreev bound states and Majorana bound states, we study the waiting time distributions (WTDs) for heterostructures, based on one dimensional edge states of a two dimensional topological insulators (TI) in combination with an proximitized s-wave superconductor (SC) and an applied magnetic field. We show for the time reversal symmetric (TRS) situation of a Josephson junction details of the WTD. This includes different transport processes, different numbers of Andreev bound states and the phase difference of the SC. We further consider a Zeeman field in the normal part of the junctions revealing novel features in the WTD along the phase transition between trivial bound states and Majorana bound states. We finally discuss clear signatures to discriminate between them.

description: Plasma volume and blood volume are imaging-derived parameters that are often used to evaluation intracranial tumors. Physiologically, these parameters are directly related, but their two different methods of measurements, T1-dynamic contrast enhanced (DCE)- and T2-dynamic susceptibility contrast (DSC)-MR utilize different model assumptions and approaches. This poses the question of whether the interchangeable use of T1-DCE-MRI derived fractionated plasma volume (vp) and relative cerebral blood volume (rCBV) assessed using DSC-MRI, particularly in glioblastoma, is reliable, and if this relationship can be generalized to other types of brain tumors. Our goal was to examine the hypothetical correlation between these parameters in three most common intracranial tumor types.
