description: We study the 'critical moments' of subcritical Gaussian multiplicative chaos (GMCs) in dimensions $d \leq 2$. In particular, we establish a fully explicit formula for the leading order asymptotics, which is closely related to large deviation results for GMCs and demonstrates a similar universality feature. We conjecture that our result correctly describes the behaviour of analogous moments of moments of random matrices, or more generally structures which are asymptotically Gaussian and log-correlated in the entire mesoscopic scale. This is verified for an integer case in the setting of circular unitary ensemble, extending and strengthening the results of Claeys et al. and Fahs to higher-order moments.

description: We present experiments on nematic aerogel oscillating in superfluid $^3$He. This aerogel consists of nearly parallel mullite strands and is attached to a vibrating wire moving along the direction of the strands. Previous nuclear magnetic resonance experiments in $^3$He confined in similar aerogel sample have shown that the superfluid transition of $^3$He in aerogel occurs into the polar phase and the transition temperature ($T_{ca}$) is only slightly suppressed with respect to the superfluid transition temperature of bulk $^3$He. In present experiments we observed a change in resonant properties of the vibrating wire at $T=T_{ca}$ and found that below $T_{ca}$ an additional resonance mode is excited which is coupled to the main resonance.

description: The notions Golodness and tightness for simplicial complexes come from algebra and geometry, respectively. We prove these two notions are equivalent for 3-manifold triangulations, through a topological characterization of a polyhedral product for a tight-neighborly manifold triangulation of dimension $\ge 3$.

description: While mapping a quantum circuit to the physical layer one has to consider the numerous constraints imposed by the underlying hardware architecture. Connectivity of the physical qubits is one such constraint that restricts two-qubit operations, such as CNOT, to "connected" qubits. SWAP gates can be used to place the logical qubits on admissible physical qubits, but they entail a significant increase in CNOT-count. In this paper we consider the problem of reducing the CNOT-count in Clifford+T circuits on connectivity constrained architectures, like noisy intermediate-scale quantum (NISQ) computing devices. We "slice" the circuit at the position of Hadamard gates and "build" the intermediate {CNOT,T} sub-circuits using Steiner trees, significantly improving on previous methods. We compared the performance of our algorithms while mapping different benchmark and random circuits to some well-known architectures such as 9-qubit square grid, 16-qubit square grid, Rigetti 16-qubit Aspen, 16-qubit IBM QX5 and 20-qubit IBM Tokyo. Our methods give less CNOT-count compared to Qiskit and TKET transpiler as well as using SWAP gates. Assuming most of the errors in a NISQ circuit implementation are due to CNOT errors, then our method would allow circuits with few times more CNOT gates be reliably implemented than the previous methods would permit.

description: Recent years have witnessed the rapid growth of Small Private Online Courses (SPOC) which is able to highly customized and personalized to adapt variable educational requests, in which machine learning techniques are explored to summarize and predict the learner's performance, mostly focus on the final grade. However, the problem is that the final grade of learners on SPOC is generally seriously imbalance which handicaps the training of prediction model. To solve this problem, a sampling batch normalization embedded deep neural network (SBNEDNN) method is developed in this paper. First, a combined indicator is defined to measure the distribution of the data, then a rule is established to guide the sampling process. Second, the batch normalization (BN) modified layers are embedded into full connected neural network to solve the data imbalanced problem. Experimental results with other three deep learning methods demonstrates the superiority of the proposed method.

description: Il y a quelques années, j’ai eu la chance de participer à des projets de PRI, découvrant ainsi l’interdisciplinarité. L’année dernière, lors de mon cours de didactique des sciences naturelles, nous avons consacré un semestre entier à la pratique de l’interdisciplinarité. J’ai trouvé ce thème non seulement très intéressant, mais j’y ai également vu un moyen de rendre plus dynamique l’enseignement de certains thèmes en les mettant en relation. A la fin de mes études à la HEP, je serai maître spécialiste en sciences naturelles et en éducation physique et sportive. Ce travail s’intéresse aux effets positifs d’un projet interdisciplinaire sur l’apprentissage d’une matière en sciences naturelles. La question principale de ce travail concerne l’application pratique de cours théoriques de sciences naturelles portant sur le corps humain dans le cadre de l’éducation physique : quel serait l’impact d’une mise en pratique en salle de sport d’un sujet théorique de sciences naturelles sur la motivation et la compréhension des élèves du dit sujet ? Cette recherche a été menée dans une classe de 8VSG dans un établissement lausannois. Durant six semaines, les élèves ont reçu un enseignement de sciences naturelles dont le thème a été repris en cours d’éducation physique et sportive afin d’en faire une application pratique sous forme de travail de groupe traitant d’une analyse de mouvement sportif en relation aves le cours théorique d’anatomie humaine. Les résultats de cette recherche ont montré plusieurs aspects positifs : ce projet a été accueilli positivement par la moitié de la classe. Cette même moitié a déclaré que le fait d’appliquer une théorie vue en salle de classe dans un cours pratique et de pouvoir appliquer cette dernière dans des mouvements concrets, leur a aidé dans la compréhension de la matière et a augmenté leur sentiment d’efficacité personnelle. Ce travail a également mis en évidence le fait que les élèves ont une idée bien arrêtée sur les buts du cours d’éducation physique et sportive. Il est difficile de leur faire faire quelque chose qui sort de leur routine et de leurs habitudes. Ce travail a montré que les élèves pensent que ce cours est en place uniquement à titre de défouloir et qu’il ne faut surtout pas commencer à réfléchir théoriquement sur un sujet pendant ces périodes. Cette recherche montre également l’importance de la diversité dans les moyens d’enseignements et les différents moyens pour y parvenir. Elle essaie de donner certaines pistes de recherches futures dans ce domaine qui ne demande qu’à être exploité.

description: Esta investigación describe y analiza el efecto de priming estructural interlingüístico durante dos prácticas de interpretación consecutiva dialógica español-inglés-español. Las estructuras que se contemplan para realizar el análisis en términos de priming estructural interlingüístico son estructuras ditransitivas en ambas lenguas dado que estas estructuras permiten una configuración diferente de sus valencias sin ser agramaticales; lo anterior permite observar la configuración de las valencias en la lengua meta y así analizar el efecto de priming. Se diseñaron dos prácticas de interpretación consecutiva dialógica las cuales sirvieron como las prácticas de interpretación que realizaron los aprendientes de interpretación. Una vez que se obtuvieron las grabaciones de los aprendientes, se procedió a transcribir, anotar y alinear los datos para compilar un corpus paralelo bilingüe denominado Corpus de Aprendientes de Interpretación (CAI); el CAI sirvió para identificar el efecto de priming en los discursos emitidos por los intérpretes. Se comprobó que existe un efecto de priming de manera bidireccional en los aprendientes de interpretación, el cual se discute a la luz de premisas psicolingüísticas y cognitivas sobre el procesamiento de ambas lenguas en intérpretes bilingües, además del almacenamiento, la representación y el uso de la información lingüística de los dos sistemas lingüísticos. Esta investigación marca un hito en los estudios de interpretación como los primeros acercamientos que se realizan a la interpretación consecutiva dialógica en términos del procesamiento psicolingüístico y cognitivo que implica la práctica interpretativa, además de incorporar diferentes disciplinas que permiten obtener un mejor entendimiento del procesamiento del intérprete.

description: This work presents the results of a research aimed at analysing the image of the Italian national service network of a multinational mobile phone company, market leader, through the measurement of its customers' satisfaction. The research that was carried out within a wider organizational development project aimed at improving the service quality of this network. It pursued two main goals: to analyse the customer's perception of the company's national service network and to measure the customer satisfaction of the assistance services provided from it. The inquiry was conducted using a specific measurement methodology of customer satisfaction, called MISURE (Cavalieri 2003), based on the detection of cultural and emotional dynamics which influence the dynamics of offer and the demand between customers and service providers, according to the psychosocial theory of the analysis of the demand and the construct of collusion, elaborated by Renzo Carli on the basis of Matte Blanco's theory of Bi-Logic (Carli 1990, 1995; Carli e Giovagnoli 2010; Matte Blanco 1975). The data gathered through a specific questionnaire were therefore processed applying descriptive and multivariate statistical techniques through the SPAD Software and interpreted according to the psychosocial models of social relationships identified by Carli and Paniccia for the psychological analysis of texts and discourses (Carli e Paniccia 2002). The results showed a customer segmentation based on different patterns of representations and satisfaction levels, which resulted as concerned more with needs for power and affiliation than with requests for specific competencies and products. The organisational development lines that emerged from the analysis are aimed at increasing the awareness of the national service network's centers about their common objectives, in relation to the needs of their customers, in order to develop a more aware and organised way of service offer, that would allow customers to have a more realistic image of the company's service network and would better orient their demand.

description: Thirty-six years after the last published record of Hyles svetlana in Uzbekistan, we found the species at multiple locations in the Kyzl-Kum desert in 2022. Furthermore, we discovered larvae feeding on Eremurus anisopterus pointing to a possible oligophagous nature of H. svetlana, as described in early days, when it was still considered a desert population of H. centralasiae. We found phenotypes in both larva and imago of H. svetlana which appeared to be more similar to Hyles euphorbiae, giving rise to more questions regarding the relationships within the genus Hyles and the genetic identity of H. svetlana.

description: Apparently, there is a renewed interested in theoretical matters among history education researchers in Germany. This is not only indicated by the foundation of a new research group within the Konferenz für Geschichtsdidaktik, but also by several recent posts in this blog journal. In a provocative and thought-provoking contribution, Christian Heuer challenges us to question established terms and concepts. Judging by their latest publications, some researchers seem to extend this challenge to historical consciousness, the central category of the German discourse on historical thinking. Does this put historical consciousness at disposition?

Christian Heuer fordert in einem provokativen und zugleich äußerst anregenden Beitrag, tradierte Begriffe und Konzepte infrage zu stellen. Diese Forderung beziehen einige Geschichtsdidaktiker offenbar auch auf die Zentralkategorie Geschichtsbewusstsein. Steht sie damit grundsätzlich zur Disposition?

description: In this paper, we consider augmented Lagrangian (AL) algorithms for solving large-scale nonlinear optimization problems that execute adaptive strategies for updating the penalty parameter. Our work is motivated by the recently proposed adaptive AL trust region method by Curtis, Jiang, and Robinson [Math. Prog., DOI: 10.1007/s10107-014-0784-y, 2013]. The first focal point of this paper is a new variant of the approach that employs a line search rather than a trust region strategy, where a critical algorithmic feature for the line search strategy is the use of convexified piecewise quadratic models of the AL function for computing the search directions. We prove global convergence guarantees for our line search algorithm that are on par with those for the previously proposed trust region method. A second focal point of this paper is the practical performance of the line search and trust region algorithm variants in Matlab software, as well as that of an adaptive penalty parameter updating strategy incorporated into the Lancelot software. We test these methods on problems from the CUTEst and COPS collections, as well as on challenging test problems related to optimal power flow. Our numerical experience suggests that the adaptive algorithms outperform traditional AL methods in terms of efficiency and reliability. As with traditional AL algorithms, the adaptive methods are matrix-free and thus represent a viable option for solving extreme-scale problems.

description: Les enseignants dans leur travail quotidien, développent des formes d’échange et de partage de leurs savoirs et de leurs pratiques. Cette collaboration prend diverses formes et varie du simple échange, en passant par la concertation jusqu'à atteindre la collaboration avec ses aspects organisationnels et structurés. Ce mémoire, à travers une démarche qualitative exploratoire, analyse la perception de la collaboration entre les enseignants du secondaire II dans un gymnase vaudois. Les enseignants du secondaire II ont en général une perception positive de la collaboration et considèrent que les affinités personnelles ou disciplinaires concourent à la mise en place de la dite collaboration. Cette dernière peut être formelle et structurée ou informelle et spontanée, et couvre des domaines didactique ou pédagogique. Les enseignants qui collaborent sont ceux qui y trouvent un intérêt ou une réponse à un besoin pressant dans les domaines cités ci-dessus, sans oublier les considérations de reconnaissance et d’estime de soi. D’autres facteurs viennent entraver la collaboration notamment les rapports au pouvoir et au savoir ainsi que l’individualisme du corps enseignant. Si les enseignants reconnaissent à la direction de l’établissement un rôle de support à la collaboration à travers la mise à disposition des moyens en temps et en matériel, il n’en demeure pas moins qu’ils tiennent à leur liberté et indépendance dans l’exercice de leur métier. Le chef de file joue également un rôle d’animateur et de facilitateur de l’entreprise de collaboration de par son statut dans l’établissement et ses rapports spécifiques avec les enseignants.

description: We introduce a family of spaces called critical varieties. Each critical variety is a subset of one of the positroid varieties in the Grassmannian. The combinatorics of positroid varieties is captured by the dimer model on a planar bipartite graph $G$, and the critical variety is obtained by restricting to Kenyon's critical dimer model associated to a family of isoradial embeddings of $G$. This model is invariant under square/spider moves on $G$, and we give an explicit boundary measurement formula for critical varieties which does not depend on the choice of $G$. This extends our recent results for the critical Ising model, and simultaneously also includes the case of critical electrical networks. We systematically develop the basic properties of critical varieties. In particular, we study their real and totally positive parts, the combinatorics of the associated strand diagrams, and introduce a shift map motivated by the connection to zonotopal tilings and scattering amplitudes.

description: Les sociétés deviennent de plus en plus hétérogènes et la Suisse n’échappe pas à ce phénomène mondial. Cela se constate dans le vécu de tous les jours, et dans l’école encore plus. Le conseil de l’Europe, dont la Suisse fait partie, avait prôné, dès les années 1970, une éducation inter- culturelle afin de favoriser l’intégration des migrants et des minorités (religieuses, ethniques, linguistiques…) européenne ou non, et a développé différents projets dans ce sens. Mais l’édu- cation interculturelle s’adresse à tous les élèves et pas seulement aux élèves étrangers. Elle leur permet de s’ouvrir à d’autres cultures, de différencier sans discriminer, de reconnaître la diversité culturelle sans jugement inégalitaire, de l’appréhender sur le mode de la réciprocité des perspectives, de lutter contre l’ethnocentrisme, de structurer leur personnalité en termes pluralistes et de lutter contre certaines formes de discrimination comme le racisme. Toute la question est de savoir comment la prendre en compte dans l’enseignement (plans d’études) et favoriser sa considération de la part aussi bien des élèves que des enseignants (approches pédagogiques, formation). En Suisse, la Conférence suisse des directeurs cantonaux de l’instruction publique (CDIP) s’était penchée sur cette question et avait proposé des disposi- tifs de formation qui prennent sérieusement en compte la dimension de la pluralité linguistique et culturelle. Mais les Plans d’études n’ont pas suivi. Très souvent, la question interculturelle est abordée sous l’angle de l’éducation à la citoyenneté. Pour notre part, nous avons voulu intéresser les élèves à l’interculturalité à travers la program- mation d’une séquence d’enseignement portant sur la relation du droit de la famille et de la religion. Le choix de cette thématique est dicté par le fait que le mariage, comme la naissance et la mort, sont entourés d’éléments identitaires culturels profonds qui sont fortement convoqués durant ces moments. La séquence a été réalisée et les résultats analysés nous ont montré tout l’intérêt des élèves à l’interculturalité et leur découverte des valeurs communes à travers la diversité des apparte- nances culturelles et religieuses de chacun.

description: L’apprentissage du vocabulaire est une entreprise complexe, parfois fastidieuse pour les apprenants, dont l’utilité est parfois sous-estimée ou considérée comme allant de soi, et par conséquent reléguée au monde obscur de l’implicite, ce qui n’aide pas les apprenants à en saisir les enjeux. L’apprentissage du vocabulaire est pourtant au cœur de l’acquisition d’une langue étrangère, et va bien au-delà de la traditionnelle mémorisation de listes. Les limites du ‘mot’ dépassent les considérations de sens et de forme, s’étendent aux dimensions culturelles et sociales des individus, et touchent aux aspects structuraux de la langue. Vocabulaire et grammaire sont intimement imbriqués et il est parfois difficile de les délimiter. Ce travail propose une synthèse de la recherche actuelle afin d’expliquer comment le vocabulaire s’organise dans notre mémoire et quelles sont les implications de cette organisation sur la manière d’évaluer le vocabulaire. A partir de cette réflexion théorique, il s’applique à expérimenter trois types de tests de vocabulaire différents, afin de déterminer leur pertinence par rapport à une démarche ayant comme objectif le développement chez les apprenants d’une compétence de communication efficace. Ce travail tente par conséquent de répondre aux questions suivantes : Que visent les différents tests ? Quels tests soutiennent une perspective communicationnelle ? Comment les élèves réagissent-ils face aux différents types de tests ? L’expérimentation s’est déroulée sur une année scolaire (2011-2012) dans une classe de 24 élèves de 1ère année de Diplôme, avec comme discipline d’étude l’anglais. Trois tests de chaque type ont été soumis aux élèves, lesquels ont participé activement à cette démarche expérimentale et l’ont enrichie de leurs remarques et réflexions. La deuxième partie de ce travail présente les résultats de notre recherche, et propose des pistes pour pousser plus loin la réflexion sur ce vaste et passionnant sujet.

description: Inter-valence charge transfer (IVCT) is electron transfer between two metal $M$ sites differing in oxidation states through a bridging ligand: $M^{n+1} + M'^{m} \rightarrow M^{n} + M'^{m+1}$. It is considered that IVCT is related to the hopping probability of electron (or the electron mobility) in solids. Since controlling the conductivity of ferromagnetic semiconductors (FMSs) is a key subject for the development of spintronic device applications, the manipulation of the conductivity through IVCT may become a new approach of band engineering in FMSs. In Ru-doped cobalt ferrite CoFe$_2$O$_4$ (CFO) that shows ferrimagnetism and semiconducting transport properties, the reduction of the electric resistivity is attributed to both the carrier doping caused by the Ru substitution for Co and the increase of the carrier mobility due to hybridization between the wide Ru $4d$ and the Fe $3d$ orbitals. The latter is the so-called IVCT mechanism that is charge transfer between the mixed valence Fe$^{2+}$/Fe$^{3+}$ states facilitated by bridging Ru $4d$ orbital: Fe$^{2+}$ + Ru$^{4+}$ $\leftrightarrow$ Fe$^{3+}$ + Ru$^{3+}$. To elucidate the emergence of the IVCT state, we have conducted x-ray absorption spectroscopy (XAS) and resonant photoemission spectroscopy (RPES) measurements on non-doped CFO and Co$_{0.5}$Ru$_{0.5}$Fe$_2$O$_4$ (CRFO) thin films. The observations of the XAS and RPES spectra indicate that the presence of the mixed valence Fe$^{2+}$/Fe$^{3+}$ state and the hybridization between the Fe $3d$ and Ru $4d$ states in the valence band. These results provide experimental evidence for the IVCT state in CRFO, demonstrating a novel mechanism that controls the electron mobility through hybridization between the $3d$ transition-metal cations with intervening $4d$ states.

description: Agent-based models are a natural choice for modeling complex social systems. In such models simple stochastic interaction rules for a large population of individuals can lead to emergent dynamics on the macroscopic scale, for instance a sudden shift of majority opinion or behavior. Here, we are concerned with studying noise-induced tipping between relevant subsets of the agent state space representing characteristic configurations. Due to the large number of interacting individuals, agent-based models are high-dimensional, though usually a lower-dimensional structure of the emerging collective behaviour exists. We therefore apply Diffusion Maps, a non-linear dimension reduction technique, to reveal the intrinsic low-dimensional structure. We characterize the tipping behaviour by means of Transition Path Theory, which helps gaining a statistical understanding of the tipping paths such as their distribution, flux and rate. By systematically studying two agent-based models that exhibit a multitude of tipping pathways and cascading effects, we illustrate the practicability of our approach.

description: Artificial agents and in particular robots, i.e. agents with some form of embodiment, provide nearly unlimited possibilities to support humans in their daily lives by reliably performing hazardous, repetitive, and physically demanding tasks, removing the risk of human errors, and providing social, mental, and physical care as needed, and around-the-clock. However, for this, artificial agents need to be able to communicate with other agents, in particular humans, in a natural and efficient manner, and to autonomously learn new tasks. The most natural way for humans to tell another agent to perform a task or to explain how to perform a task is through natural language. Therefore, artificial agents need to be able to understand natural language, i.e. extract the meanings of words and phrases, which requires words and phrases to be linked to their corresponding percepts through grounding. Theoretically, groundings, i.e. connections between words and percepts, can be manually specified, however, in practice this is not possible due to the complexity and dynamicity of human-centered environments, like private homes or supermarkets, and the ambiguity inherent to natural language, e.g. synonymy and homonymy. Therefore, agents need to be able to autonomously obtain new groundings and continuously update existing groundings to account for changes in the environment and incorporate new information obtained through the agent’s sensors. Furthermore, the obtained groundings should be utilizable to learn new tasks from natural language instructions. Therefore, this thesis proposes a novel framework for simultaneous language grounding and action learning that achieves three main objectives. First, it enables agents to continuously ground synonymous words and phrases without requiring external support by another agent. Second, it enables agents to utilize external support, if available, without depending on it. Finally, it enables agents to utilize previously learned groundings to learn new tasks from language instructions.

description: Ce travail souhaite démontrer la pertinence qu’il y a à enseigner la poésie en école professionnelle aujourd’hui. L’enseignement du français dans le milieu professionnel étant souvent réduit à son aspect pratique, nous nous sommes demandé de quelle façon nous pouvions aborder la poésie dans un tel contexte. C’est au travers d’une expérience vécue en stage que nous nous proposons d’explorer des pistes de réflexions. Un artiste est ainsi venu en classe d’école professionnelle rapper les poèmes de Baudelaire et animer des ateliers d’écriture. Il est le co-auteur d’un spectacle qu’il a joué en 2008 « Baudelaire in progress » où il interprète certains poèmes de l’auteur. Le succès de cette expérience nous a donné envie d’en parler et d’en explorer les enjeux. Nous avons souhaité questionner l’aspect sacré de la littérature et le mettre en dialogue avec une culture actuelle de l’oral et du rythme. Nous avons également évoqué les archétypes ancrés dans l’inconscient collectif qui prônent le primat des métiers « cérébraux » sur les professions dites plus « manuelles ». Cela nous mène indirectement à la problématique néanmoins centrale de la valorisation du gymnase au détriment des écoles professionnelles. Sans prétendre changer les mentalités, nous avons jugé important de prendre en compte ce paramètre capital pour traiter le sujet. Enfin, nous proposons une façon d’aborder la poésie centrée autour de la création visant à décomplexer l’acte d’écrire. Pour conclure, nous insistons sur l’idée d’une collaboration des enseignants avec les entités artistiques actuelles et tous types de supports modernes de communication de la langue française.

description: In this paper we study the maximum number $N$ of limit cycles that can exhibit a planar piecewise linear differential system formed by two pieces separated by a straight line. More precisely, we prove that this maximum number satisfies $2\leq N \leq 3$ if one of the two linear differential systems has its equilibrium point on the straight line of discontinuity.

description: Los adultos mayores tienen necesidades específicas propias de este grupo poblacional. Para 2050, una de cada cuatro personas que viven en Europa y América del Norte podría tener 65 años o más. En 2018, por primera vez en la historia, las personas de 65 años o más superaron en número a los niños menores de cinco años en todo el mundo. Se estima que el número de personas de 80 años o más se triplicará, de 143 millones en 2019 a 426 millones en 2050. El objetivo de este estudio fue desarrollar una propuesta de ámbitos e indicadores con base en la revisión crítica de estudios, métodos y normas dirigidas al diseño y habitabilidad para el adulto mayor. Se recopilaron y revisaron fuentes de información especializada, así como normas de referencia internacional. Se obtuvo como resultado una propuesta de indicadores que contemplan los ámbitos físico, psicológico y social. Aun cuando existe una visión que contempla este sector de la población, el desarrollo de acciones aisladas no considera las necesidades reales de habitabilidad para los adultos mayores. Se requiere atender no solo
The generalized Langevin equation in harmonic potentials: Anomalous diffusion and equipartition of energy

description: We consider the generalized Langevin equation (GLE) in a harmonic potential with power law decay memory. We study the anomalous diffusion of the particle's displacement and velocity. By comparison with the free particle situation in which the velocity was previously shown to be either diffusive or subdiffusive, we find that, when trapped in a harmonic potential, the particle's displacement may either be diffusive or superdiffusive. Under slightly stronger assumptions on the memory kernel, namely, for kernels related to the broad class of completely monotonic functions, we show that both the free particle and the harmonically bounded GLE satisfy the equipartition of energy condition. This generalizes previously known results for the GLE under particular kernel instances such as the generalized Rouse kernel or (exactly) a power law function.

description: Thresholds occur in the dynamics of many biological communities. Here we model a persistence type threshold which has been shown experimentally to exist in hyperparasitised flukes in the cockle, a shellfish. Our model consists of a periodically driven slow-fast host-parasite system of equations for a slow flukes population and a fast Unikaryon hyperparasite population. The model exhibits two branches of the critical curve crossing in a transcritical bifurcation scenario. We discuss two thresholds due to immediate and delayed exchange of stability effects; and we derive algebraic relationships for parameters of the periodic solution in the limit of the infinite ratio of the time scales. Flukes parasitise cockles and in turn are hyperparasitised by the microsporidian Unikaryon legeri; the life cycle of flukes includes several life stages and a number of different hosts. That is, the flukes-hyperparasite system in a cockle is part of a larger estuarine ecosystem of species involving parasites, shellfish and birds which prey on shellfish. A population dynamics model which accounts for such multi-species interactions and includes the fluke-hyperparasite model in a cockle as a subsystem is presented. We provide evidence that the threshold effect we observed in the flukes-hyperparasite subsystem remains apparent in the multi-species system. Assuming that flukes damage cockles, and taking into account that the hyperparasite is detrimental to flukes, it is natural to suggest that the hyperparasitism may support the abundance of cockles and, thereby, the persistence of the ecosystem, including shellfish and birds. We confirm the possibility of this scenario in our model by removing the hyperparasite and demonstrating that this may result in a substantial drop in cockle numbers. The result indicates a possible significant role for the microparasite in this estuarine ecosystem.

description: We prove localization with high probability on sets of size of order $N/\log N$ for the eigenvectors of non-Hermitian finitely banded $N\times N$ Toeplitz matrices $P_N$ subject to small random perturbations, in a very general setting. As perturbation we consider $N\times N$ random matrices with independent entries of zero mean, finite moments, and which satisfy an appropriate anti-concentration bound. We show via a Grushin problem that an eigenvector for a given eigenvalue $z$ is well approximated by a random linear combination of the singular vectors of $P_N-z$ corresponding to its small singular values. We prove precise probabilistic bounds on the local distribution of the eigenvalues of the perturbed matrix and provide a detailed analysis of the singular vectors to conclude the localization result.

Optimal installation of renewable electricity sources: the case of Italy

description: Starting from the model in Koch-Vargiolu (2019), we test the real impact of current renewable installed power in the electricity price in Italy, and assess how much the renewable installation strategy which was put in place in Italy deviated from the optimal one obtained from the model in the period 2012--2018. To do so, we consider the Ornstein-Uhlenbeck (O-U) process, including an exogenous increasing process influencing the mean reverting term, which is interpreted as the current renewable installed power. Using real data of electricity price, photovoltaic and wind energy production from the six main Italian price zones, we estimate the parameters of the model and obtain quantitative results, such as the production of photovoltaic energy impacts the North zone, while wind is significant for Sardinia and the Central North zone does not present electricity price impact. Then we implement the solution of the singular optimal control problem of installing renewable power production devices, in order to maximize the profit of selling the produced energy in the market net of installation costs. We extend the results of \cite{KV} to the case when no impact on power price is presented, and to the case when $N$ players can produce electricity by installing renewable power plants. We are thus able to describe the optimal strategy and compare it with the real installation strategy that was put in place in Italy.
