Grafi aleatori - il modello di Erdos-Rényi

Dopo aver dato una definizione formale per il modello di Erdos-Rényi, si dimostra che in un grafo ER il grado dei nodi (misura della connessione) risulta essere una variabile aleatoria con distribuzione binomiale, mentre il clustering (misura della densità di archi a livello locale) tende a zero. Successivamente si determinano le funzioni soglia per alcune proprietà monotone particolarmente significative, consentendo così di descrivere diverse configurazioni possibili per un grafo ER al variare dei suoi parametri. Infine, si mostra come si possano utilizzare i grafi ER per modellizzare la diffusione di una malattia infettiva all’interno di una popolazione numerosa.

Geochemistry and isotopic ratios of basalts obtained during R/V Akademik Nikolaj Strakhov cruise ANS25

Based on the investigation of samples recovered during Cruise 25 of the R/V ''Akademik Nikolai Strakhov'', the character of magmatism was determined in the flank parts of the rift zone at the 74°05'N and 73°50'N region, where the direction of the rift valley changes from the north-northwest in the Knipovich Ridge to the northeast-trending structures of the Mohns Ridge. It was shown that the tholeiitic magmas of this region shows all the geochemical characteristics of TOR-2, which is typical of the Mohns Ridge and most oceanic rift zones worldwide, and differ from the basalts of the Knipovich Ridge, which are assigned to a shallower type of tholeiitic magmatism (Na-TOR). The persistent depletion of the magmas in terms of lithophile element contents and radiogenic isotope ratios of Sr, Nd, and Pb reflects the conditions of their formation during the ascent of the depleted oceanic mantle, which has occurred without significant complications since the early stages of the formation of the Mohns Ridge.
