On the influence of network structure on the resilience and losses of financial systems

Weinvestigate resilience to defaults in financial networks, where nodes hold shares in a common set of external assets. Price fluctuations in these assets can trigger shareholder defaults, propagating through the network and causing default cascades. In particular, we conduct a series of numerical experiments to elucidate the influence of the network structure on the financial system. Our investigation explores the effects of sparsity versus connectivity, clustering, and liability heterogenei...

A memristive computational neural network model for time-series processing

In this work, we introduce a novel computational framework inspired by the physics of memristive devices and systems, which we embed into the context of Recurrent Neural Networks (RNNs) for time-series processing. Our proposed memristive-friendly neural network architecture leverages both the principles of Reservoir Computing (RC) and fully trainable RNNs, providing a versatile platform for sequence learning. We provide a mathematical analysis of the stability of the resulting neural network ...

Metodología para evaluar el desempeño en economía circular en el reciclaje de PET en Cuba / (Methodology for evaluating performance in the circular economy in PET recycling in Cuba)

Plastics, including polyethylene terephthalate (PET), generate negative effects on society, the environment, and the economy, imposing externalities and additional costs. In this context, the circular economy uses a systemic approach to maintain the circular flow of resources through recovery, retention, or value addition. Its implementation is a priority in the management and recycling of this resource; however, there are methodological gaps. The sequence of operations for PET recycling in ...

Funzionalità e modernità: gli edifici per l’educazione fascista in Alba alla prova del tempo

The experiments and discoveries of early 20th-century architecture yielded particularly significant results even in Italy's provincial contexts. The social and economic growth recorded in Alba led the fascist regime in the 1930s to build several youth-oriented buildings, including a boarding school and a gymnasium. Despite having very different architectural backgrounds, these two buildings represent the most important examples of the Modern movement in the city. They also stand as a testamen...

Discovering SpatioTemporally Invariant Event Patterns From Mobility Data

The discovery of sequential patterns from spatiotemporal data is known to be a very complex data mining task. The relevance of spatiotemporal patterns to study event correlations in mobility data is established. Prior works addressed either the separate analysis of spatial and temporal dependencies among data, such as the co-location of events, or the study of the joint spatiotemporal properties of the trajectories observed over a region of interest. The aim of this paper is instead to overco...
