The advantage of 2D-3D image registration methods versus direct image-to-patient registration, is that these methods generally do not require user interaction (such as manual annotations), additional machinery or additional acquisition of 3D data. A variety of intensity-based similarity measures has been proposed and evaluated for different applications. These studies showed that the registrati...

The origin and radiation of nacellid limpets (genera, Cellana and Nacella) are not well-resolved, but fossil records provide evidence of a historical range spanning throughout the PaciWc, including North America (Lindberg and Hickman, 1986) north and south Australia, New Zealand, Java, Chile, and east and west Antarctica (Powell, 1973). The modern biogeographic range of Cellana is mostly tropic...

The idea that demographic change may spur or slow down technological change has become widely accepted among evolutionary archaeologists and anthropologists. Two models have been particularly influential in promoting this idea: a mathematical model by Joseph Henrich, developed to explain the Tasmanian loss of culture during the Holocene; and an agent-based adaptation thereof, devised by Powell ...

In their cross-sectional study, Powell et al found no evidence that genetic ancestry or self-reported ethnicity effected lung function among US smokers, in particular no evidence of a reduced risk of COPD in Hispanics (Hispanic paradox) previously described in a prospective study by Bruse et al. This observation might be due, in part, to the definition of Hispanic and lighter smoking histories ...

Sparganocosma docsturnerorum Brown, new genus and new species, is described and illustrated from Área de Conservación (ACG) in northwestern Costa Rica. The new genus shares a long, crescent- or ribbon-shaped signum in the corpus bursae of the female genitalia with Aesiocopa Zeller, 1877, Amorbia Clemens, 1860, Amorbimorpha Kruse, 2011, Coelostathma Clemens, 1860, Lambertiodes Diakonoff, 1959, P...

In this paper, we analyze the thermal radiation and chemical reaction impacts on MHD peristaltic motion of the Eyring-Powell fluid through a porous medium in a channel with compliant walls under slip conditions for velocity, temperature, and concentration. Assumptions of a long wave length and low Reynolds number are considered. The modeled equations are computed by using the perturbation metho...
