Collective communication performance is critical in a number of MPI
applications. In this paper we focus on two widely used primitives,
broadcast and reduce, and present experimental results obtained on a cluster
of PC connected by Myrinet.
We compare the performance of the MPICH primitives… |

Background
COVID-19 lockdown caused sudden changes in people's lifestyle, as a consequence of the forced lockdown imposed by governments all over the world. We aimed to evaluate the impact of lockdown on body mass index (BMI) in a cohort of allergic children and adolescents.
Methods
From the first… |

Immunosenescence is thought to result from cellular aging and to reflect exposure to environmental stressors and antigens, including cytomegalovirus (CMV). However, not all of the features of immunosenescence are consistent with this view, and this has led to the emergence of the sister theory of "… |

We present a fast implementation of a recently proposed speech
compression scheme, based on an all-pole model
of the vocal tract. Each frame of the speech signal is analyzed by storing
the parameters of the complex damped exponentials deduced from the
all-pole model
and its initial conditions.… |

Given a graph G with a label (color) assigned to each edge (not necessarily properly) we look for an hamiltonian cycle of G with the minimum number of different colors. The problem has several applications in telecommunication networks, electric networks, multimodal transportation networks, among… |

We briefly review some aspects of the anomalous diffusion, and its relevance in reactive systems. In particular we consider strong anomalous diffusion characterized by the moment behaviour <(x(t)(q)> similar to t(qv)(q), where v(q) is a non constant function, and we discuss its consequences.… |

We present an in silico model that simulates the immune system responses to tumor cells in naive and vaccinated mice. We have demonstrated the ability of this model to accurately reproduce the experimental results.
Motivation: In vivo experiments on HER-2/neu mice have shown the effectiveness of… |
