Scyphomedusae undergo a predictable ontogenetic transition from a conserved, universal larval form to a diverse array of adult morphologies. This transition entails a change in bell morphology from a highly discontinuous ephyral form, with deep clefts separating eight discrete lappets, to a continuous solid umbrella-like adult form. We used a combination of kinematic, modeling, and flow visuali...

Et Tu, Torsten? This critique of my Economic Policy paper generates many emotions. It is certainly an honor for my research to be taken seriously by such an eminent scholar as my friend Torsten Persson. And while any publicity is good, a negative citation dominates a positive one. There is irony; I came up with the original idea in a hallway conversation with Harry Flam a few feet from Persson’...

A traditional view of the nature of species holds that populations within species maintain genetic cohesion through substantial intraspecific gene flow and that the whole genome of a species is protected from interspecific gene flow by strong reproductive isolation. Both aspects of this view have been challenged. Reproductive barriers between recently evolved species can be incomplete and perme...

This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological informatio...

Two new species of Dolichothele Mello-Leitão, 1923 are described from Brazil and Bolivia, D. mottaisp. n. from Distrito Federal and the state of Goiás, Brazil, and D. camargorumsp. n. from the state of Rondônia, Brazil, and the La Paz region, Bolivia. Males of the two new species resemble Dolichothele bolivianum (Vol, 2001) in having a small subapical keel on the distal embolus and females in p...

A t the start of mitosis, the nuclear envelope breaks down and merges with the endoplasmic reticulum (ER). At the same time, the nuclear pore complexes that mediate transport across the inner and outer membranes of the envelope also disassemble. Transmembrane pore proteins move into the ER, while soluble components disperse into the cyto-plasm. Lu et al. use rapid, live-cell 3D imaging to estab...

Breast cancer is the most common malignancy among women (DeVita, 2008) and early diagnosis is obviously the effective way for saving patients and plays an essential role to improve prognosis (Yarbrough and Braden, 2001; Lu, 2001). Iranian women are not excepted from this rule, as it has the high prevalence rate in Iran with increasing trend along recent decade (Center for Disease Control and Pr...

— We study the microlocal analyticity of solutions u of the nonlinear equation ut = f(x, t, u, ux) where f(x, t, ζ0, ζ) is complex-valued, real analytic in all its arguments and holomorphic in (ζ0, ζ). We show that if the function u is a C2 solution, σ ∈ CharLu and 1 i σ([Lu, Lu]) < 0 or if u is a C3 solution, σ ∈ CharLu, σ([Lu, Lu]) = 0, and σ([Lu, [Lu, Lu]]) 6= 0, then σ / ∈WFau. Here WFau de...
