Making Sense of Social Complexity through Strange Attractors
Strange attractors – emerging out of the chaotic dynamics of the thoughts and feelings constantly swarming in the mental space of each individual – encapsulate topologies of meaning-making units and offer a key to a unified semiotic and cognitive understanding of meaning. Being dynamic constructs, Strange Attractors of Meaning have both spatial and temporal characteristics. The spatial characte...

Class III Semaphorins (SEMA3) comprise a family of chemokines that have been implicated as negative regulators of axonal guidance, angiogenesis and tumor progression. It has been demonstrated previously that one SEMA3, SEMA3F, may have therapeutic potential in the treatment of cancer. When transfected with SEMA3F, the highly metastatic human melanoma cell line A375SM was found to exhibit a high...

Land cover, vegetation green leaf area index (LAI) and the fraction of incident photosynthetically active radiation absorbed by vegetation (FPAR) govern the exchange of energy, momentum and mass (water and carbon dioxide, for example) between the Earth’s surface and the atmosphere. These variables are operationally derived from measurements of the Multiangle Imaging SpectroRadiometer (MISR) abo...

Biological mixtures comprised of multiple individuals’ tissues or bodily fluids are commonly encountered and gathered during crime scene evidence collection. Sexual assault samples are one such mixture, usually comprised of epithelial cells and sperm. Sexual assault mixtures may contain a large amount of non-sperm cells in comparison to sperm cells. In such instances, it is imperative to separa...
متن کاملHow strange a non-strange heavy baryon?
We give some general arguments in favor of the large magnitude of matrix elements of an operator associated with nonvalence quarks in heavy hadrons. We estimate matrix element 1 2mΛb 〈Λb|s̄s|Λb〉 ≃ 1 ÷ 2 for Λb baryon whose valence content is b, u, d quarks. This magnitude corresponds to a noticeable contribution of the strange quark into the heavy baryon mass 1 2mΛb 〈Λb|mss̄s|Λb〉 ≃ 200 ÷ 300MeV ....
