Concordia discors. Del Noce e Matteucci a confronto
No full textAugusto Del Noce and Nicola Matteucci have confronted each other for about thirty years, at times directly (in the years in which Del Noce collaborated with "Il Mulino"), at others indirectly, on a series of themes of great political and cultural importance. Among these, the limits of the antifascist paradigm as foundation of the Republican democracy, the interpretation of the Risorgimento and the analysis of '68 events. This confrontation, that also reaches to the evaluation of the Unites States as a model of liberal society, assumes a particular interest for both the intellectual relevance and the different cultural background of the two protagonists (Del Noce, of catholic formation, Matteucci, of liberal-laical culture), besides the importance of the discussed themes. Anyhow, only some of the moments of their confrontation have been by now reconstructed in depth. Purpose of this essay is to fill this gap offering an overall reconstruction, even though necessarily synthetic, of this important chapter of the Italian intellectual history of '900

Decomposing Global Quantitative Properties into Local Ones.
No full textIn this paper we address the problem of identifying what local properties the sub-components of a system have to satisfy in order to guarantee a (security) property on the behaviour of the whole system.We associate each action with a value. Hence, we end up with quantitative properties on them, which are specified through a modal logic equipped with a parametric algebraic structure (i.e., a c-semiring). The aim is to have a value related to the satisfaction of a formula. Startingfrom the behaviour of a general distributed system (or context ), we propose a formal approach to decompose a global quantitative property intothe local quantitative properties to be satisfied by its sub-contexts

Considerazioni storico-artistiche sull'attribuzione del dipinto San Francesco Stimmatizzato a Tiziano Vecellio
No full textNell’articolo si riporta l’anamnesi storico-artistica del dipinto ad olio su tela (280x190 cm) San Francesco Stimatizzato, proveniente dalla chiesa di San Francesco
d’Assisi a Trapani (annessa al Convento dei Padri Conventuali Francescani), e
conservato nel Museo Interdisciplinare regionale “Agostino Pepoli” di Trapani.
L’anamnesi storico-artistica del San Francesco Stimmatizzato, effettuata sulla documentazione bibliografica e archivistica, insieme all’indagine diagnostico-analitica dell’opera, contribuisce a confutare o confermare l’attribuzione a Tiziano,
conducendo in tal maniera ad un giudizio più corretto ed affidabile
Heterogeneous Datasets for Federated Survival Analysis Simulation
No full textHeterogeneous Datasets for Federated Survival Analysis Simulation
This repo contains three algorithms for constructing realistic federated datasets for survival analysis. Each algorithm starts from an existing non-federated dataset and assigns each sample to a specific client in the federation. The algorithms are:
uniform_split: assigns each sample to a random client with uniform probability;
quantity_skewed_split: assigns each sample to a random client according to the Dirichlet distribution [3, 4];
label_skewed_split: assigns each sample to a time bin, then assigns a set of samples from each bin to the clients according to the Dirichlet distribution [3, 4].
For more information, please take a look at our paper at https://arxiv.org/abs/2301.12166 [1].

Heterogheneous_Datasets_for_Federated_Survival_Analysis_Simulation.pdf: the conference paper describing the work.
Installation
Federated Survival Datasets is built on top of numpy and scikit-learn. To install those libraries you can run pip install -r requirements.txt. To import survival datasets into your project, we strongly recommend SurvSet (https://github.com/ErikinBC/SurvSet) [2], a comprehensive collection of more than 70 survival datasets.
Usage
import numpy as np
import pandas as pd
from federated_survival_datasets import label_skewed_split
# import a survival dataset and extract the input array X and the output array y
df = pd.read_csv("metabric.csv")
X = df[[f"x{i}" for i in range(9)]].to_numpy()
y = np.array([(e, t) for e, t in zip(df["event"], df["time"])], dtype=[("event", bool), ("time", float)])
# run the splitting algorithm
client_data = label_skewed_split(num_clients=8, X=X, y=y)
# check the number of samples assigned to each client
for i, (X_c, y_c) in enumerate(client_data):
print(f"Client {i} - X: {X_c.shape}, y: {y_c.shape}")
We provide an example notebook in the zipped folder to illustrate the proposed algorithms. It requires scikit-survival, seaborn, and pandas.
