Abstract

We study the diameter, or the mean distance between sites, in a scale-free network, having N sites and degree distribution p(k) ∝ k −λ , i.e. the probability of having k links outgoing from a site. In contrast to the diameter of regular random networks or small world networks which is known to be d ∼ ln N , we show, using analytical arguments, that scale free networks with 2 < λ < 3 have a much smaller diameter, behaving as d ∼ ln ln N . For λ = 3, our analysis yields d ∼ ln N/ ln ln N , as obtained by Bollobas and Riordan, while for λ > 3, d ∼ ln N . We also show that, for any λ > 2, one can construct a deterministic scale free network with d ∼ ln ln N , and this construction yields the lowest possible diameter.

Transnational lifestyles among Russian Israelis: a follow‐up study

“…Older immigrants are more prone to retain their ethnic and cultural characteristics and have a lower potential for occupational and social integration. Second, as a result of intense assimilation and intermarriage among Soviet Jews, about one-third of the immigrants are either partly Jewish or non-Jewish, in other words they are the spouses or non-Jewish children of repatriates recognized by the state as Jews 2 (Cohen and Susser 2009). Migration split many of the ethnically mixed families because the numerous parents, siblings and other relatives of non-Jewish spouses stayed at home.…”

“…Yet, by the Law of Return, all children and grandchildren of Jews, and their immediate families, have a right to Israeli citizenship or permanent residence. This gap between religious and civic definitions of Jewishness creates many conflicts, particularly over matters of marriage, divorce and family reunification (Cohen and Susser 2009). 3.…”

Structure and interactions in fluids of prolate colloidal ellipsoids: Comparison between experiment, theory, and simulation

“…This oversampling improves the accuracy of our particle tracking procedures. 18,19 We used particle tracking codes 43 based on the PLuTARC implementation 18 of the Crocker and Grier algorithm 19 for tracking simple spheres. We have generalized the code to track ellipsoids.…”

Ultraorthodox Jewish Fathers in Israel: Predictors of Involvement and Acceptance

“…Social support was examined using the Hebrew language social support questionnaire developed by Cohen (1992). The questionnaire listed five areas of assistance (household chores, child care, financial support, emotional support, and advice) and asked respondents to rate, on a 4-point scale, how much help they were currently receiving from each of the following sources: their wives’, families of origin, friends, and coworkers (in our analyses, we introduced support from wives, families, and friends, in light of the importance attributed to mutual support in ultraorthodox society).…”
