Vu Tran, \u2714
No full textVu Tran was born in Da Nang Vietnam and grew up in the Central Florida area. In the summer of 2010, she enrolled in UCF to begin her undergraduate studies in Anthropology. Her research interests include dental anthropology, paleopathology, skeletal trauma, and interpersonal violence. Vu has completed an Independent Study in Dental Anthropology and has performed Independent Research on Violence within the past school year. In the summer of 2013, Vu received an NSF REU grant and traveled to Cyprus to participate in the Athienou Archaeological Project. Vu is currently working on her Honors in the Major undergraduate thesis. Her topic focuses on the paleodemography of a population from Kuelap, Peru. Her future research plans involve topics on craniofacial trauma and dental trauma. She hopes to one day become a bioarchaeologist, researching and teaching at a university.https://stars.library.ucf.edu/mcnair_gallery/1102/thumbnail.jp

No full textRhyacobates anderseni Tran & Yang, 2006 Rhyacobates anderseni Tran & Yang, 2006: 14 –16, Figs. 7 –16, 27 (type locality: Vu Quang, Ha Tinh Prov., Vietnam). Material examined. For holotype and paratypes, see Tran & Yang (2006). Size. Males, length 6.0– 6.1 (allotype 6.0), width 1.83–1.85 (allotype 1.83) (apterous), length 6.1–6.2, width 1.85–1.88 (macropterous); females, length 6.8 –7.0 (holotype 6.8), width 2.52–2.57 (holotype 2.52) (apterous). Remarks. The followings are diagnostic characteristics of R. anderseni: the mesonotum of the male has a slender yellow stripe on the posterior half; the mesonotum of the female has a broader yellow median marking on the posterior three-fifths; the abdomen of the male is relatively short; in lateral view, abdominal segment 8 of the male has a concave ventral surface; the male proctiger has round angular projections on each side (see Tran & Yang 2006: Fig. 12); the male paramere is falciform, slightly broad, long, and not conspicuously setose (see Tran & Yang 2006: Figs. 13, 14); the metanotum of the female has a pointed median process on the posterior margin (see Tran & Yang 2006: Fig. 7); the abdomen of the female is short (length about 0.2 times body length), sternum 7 is long, almost enclosing the genital segments with its connexival margin raised slightly upwards, with a pair of long posterior projections pointing outwards and downwards (see Tran & Yang 2006: Figs. 8, 9), and its posterior margin is almost straight, bearing two short lateral processes (see Tran & Yang 2006: Fig. 10). For detailed comparisons of Rhyacobates anderseni with its congeners and other ptilomerine genera (Andersenius and Pleciobates), refer to Tran & Yang (2006: 16). Habitats. See Tran & Yang (2006: 16). Distribution. Vietnam: Ha Tinh. China: Yunnan.Published as part of Tran, A. D. & Nguyen, X.

Reaching a Consensus on Random Networks: The Power of Few
No full textA community of n individuals splits into two camps, Red and Blue. The individuals are connected by a social network, which influences their colors. Everyday, each person changes his/her color according to the majority of his/her neighbors. Red (Blue) wins if everyone in the community becomes Red (Blue) at some point.
We study this process when the underlying network is the random Erdos-Renyi graph G(n, p). With a balanced initial state (n/2 persons in each camp), it is clear that each color wins with the same probability.
Our study reveals that for any constants p and ε, there is a constant c such that if one camp has n/2 + c individuals at the initial state, then it wins with probability at least 1 - ε. The surprising fact here is that c does not depend on n, the population of the community. When p = 1/2 and ε = .1, one can set c = 6, meaning one camp has n/2 + 6 members initially. In other words, it takes only 6 extra people to win an election with overwhelming odds. We also generalize the result to p = p_n = o(1) in a separate paper
