Dynamical systems.

Flow Structure and fluid transport via advection around pectoral fin of larval ZebraFish
are studied numerically using Immersed Boundary Method, Lagrangian Coherent
Structure, passive particle tracing, vortex core evolution and four statistically defined
mixing numbers. Experimental fish kinematics for nominal swimming case are obtained
from previous researchers and numerically manipulated to analyze the role of different
body motion kinematics, Reynolds number and fin morphology on flow structure and
transport. Hyperbolic strain field and vortex cores are found to be effective particle
transporter and their relative strength are driving force of varying flow structure and fluid
transport. Translation and lateral undulation of fish; as a combination or individual entity,
has coherent advantages and drawbacks significant enough to alter the nature of fluid
advection. Reynolds number increase enhances overall fluid transport and mixing in varying order for different kinematics and nominal bending position of fin has average
transport capability of other artificially induced fin morphology.

The 1990s ushered in what historian Susan Stryker describes as “a tremendous burst of new transgender activism” in the United States. Concomitantly, the success of Star Trek: The Next Generation led to a renaissance of US science fiction television. This dissertation asks, what is the relation between transgender (trans) politics and US science fiction (sf) television from 1990 to the present? The theoretical framework is Trans/Elemental feminism, a new paradigm developed in the dissertation. The method is multiperspectival cultural studies, which considers how the production, content, and reception of media texts and their metatexts collectively determine the texts’ meaning. The data include trade articles about the television industry; published interviews with producers; 3,175 hours of televisual content; commercial advertisements for television programs; films, novels, and webisodes (Web episodes) in selected media franchises; professional reviews; online discussion boards; fan fiction; and fan videos.
