Evolution of spoon-shaped networks

We consider a regular embedded network composed by two curves, one of them closed, in a convex domain $\Omega$. The two curves meet only in one point, forming angle of $120$ degrees. The non-closed curve has a fixed end point on $\partial\Omega$. We study the evolution by curvature of this network. We show that the maximal existence time depends only on the area enclosed in the initial loop, if the length of the non-closed curve stays bounded from below during the evolution. Moreover, the closed curve shrinks to a point and the network is asymptotically approaching, after dilations and extraction of a subsequence, a Brakke spoon.Comment: arXiv admin note: substantial text overlap with arXiv:math/0302164 by other author

Translation and Bilingualism in Monica Ali’s and Jhumpa Lahiri’s Marginalized Identities

This investigation seeks to demonstrate how Ali and Lahiri represent two different migrant experiences, Muslim and Indian, each of which functioning within a multicultural Anglo-American context. Each text is transformed into the lieu where identities become both identities-intranslation and translated identities and each text itself may be looked at as the site of preservation of native identities but also of the assimilation (or adaptation) of identity. Second-generation immigrant women writers become the interpreters of the old and new cultures, the translators of their own local cultures in a space of transition

Uniqueness of low genus optimal curves over F_2

A projective, smooth, absolutely irreducible algebraic curve X of genus g defined over a finite field F_q is called optimal if for every other such genus g curve Y over F_q one has $\#Y(F_q)\le \#X(F_q)$. In this paper we show that for $g\le 5$ there is a unique optimal genus g curve over F_2. For g=6 there are precisely two and for g=7 there are at least two.Comment: 21 page

Cold stress in captive great apes recorded in incremental lines of dental cementum

Incremental lines in dental cementum of museum specimens of 11 free-ranging great apes were compared to the respective structures in 5 captive specimens of known age-at-death, and with many known life-history parameters. While the dental cementum of the free-ranging apes was regularly structured into alternating dark and light bands, 4 out of 5 captive animals showed marked irregularities in terms of hypomineralized bands which could all be dated to the year 1963. Cementum preservation was insufficient in the fifth specimen and did not permit such a differentiation. All 4 captive apes had been kept in a zoo located in the northern hemisphere, where 1963 was characterized by an extremely cold winter. Since cold stress is a calcium-consuming process, the lack of available calcium in newly forming cementum could be responsible for the observed hypomineralization. The appositional growth characteristics of dental cementum serve as a record for such life-history events. Copyright (C) 2002 S. Karger AG, Basel
