We have studied the development of the ipsilateral retinothalamic projection in the frog Xenopus laevis by analyzing patterns of histochemical reaction product resulting from anterograde transport of horseradish peroxidase (HRP) applied to cut optic nerves in animals of various ages. We have also determined the stages during which ipsilaterally projecting ganglion cells are born using a combina...

ABSTRACT The suggestions for writing for publication given in this paper include writing with honesty, thinking clearly, considering the potential audience, sharing the article with friends, revising the article, and sending the article to the appropriate journal. Empathy for the difficulty of writing is given and illustrated with examples from Eric Hcffer, Ernest Hemingway, Art Buchwald, Chaim...

Great earthquakes, the few largest earthquakes that account for most of the Earth’s seismic energy release, have occurred at only a few subduction zones around the world. Strong locking, or ‘seismic coupling’, of the interface between plates at certain subduction zones is often invoked to explain these great earthquakes. Although past studies have correlated strong seismic coupling with a compr...

[1] We analyze high dynamic range waveform spectra to determine t* values for both P and S waves from earthquakes in southern California. We invert the t* values for threedimensional (3-D) frequency-independent QP and QS regional models of the crust. The models have 15 km horizontal grid spacing and an average vertical grid spacing of 4 km, down to 22 km depth, and extend from the U.S.-Mexico b...

correct context has taken a lot of work. Yanagida's approach to this work has been influenced by his location — starting with the choice of fission yeast. " Working on a remote island, I thought it may be better to work on a more obscure organism, " he says. And once that work was started, " we were quite happy to study these mutants in an isolated fashion. " But if the research was somewhat is...

Abstract The ranges of the parameters wind and temperature (refractive) turbulence are estimated corresponding to four-point scale intensity at flight altitudes in free atmosphere. It is shown that estimates both variance radial velocity measured with a coherent lidar direction structural constant refractive index from measurements make it possible judge potential danger bumpy aircraft clear-ai...
