Is sovereign borrowing so different from corporate debt that there is no need for bankruptcy-style procedures to protect debtors? With the waiver of immunity, sovereign debtors who already face severe disruption from short-term creditors grabbing their currency reserves are also exposed to litigious creditors trying to seize what assets they can in a 'race(More)
In the face of increasing CO 2 emissions from conventional energy (gasoline), and the anticipated scarcity of crude oil, a worldwide effort is underway for cost-effective renewable alternative energy sources. Here, we review a simple line of reasoning: (a) geologists claim that much crude oil comes from diatoms; (b) diatoms do indeed make oil; (c)(More)
We have discovered a series of expansion and contraction, solitary waves that correlate with discrete steps of differentiation in the urodele amphibian axolotl embryo (Ambystoma mexicanum). Here we examine in detail the proposition that the blastopore is a set of differentiation waves. We superimposed the image of the axolotl fate map onto our digitized(More)

Mechanics is shown to be an important, perhaps central component to the differentiation and development of embryos. Mechanics of the nucleus may also be involved in determining which genes are expressed in a given cell. There are two major approaches at present to the mechanics of differentiation in embryos: morphomechanics and differentiation waves. These(More)
The visually impaired have limited access to the world of mobile devices. Our goal was to design a handheld mobile device to overcome limitations such as reliance on visual display and lack of audio and tactile feedback. We built a prototype handheld device using a combination of tactile feedback and auditory display based on preliminary research and(More)
The following courses are required for all tracks: All undergraduate majors in earth science take a 4-course core sequence, typically in the sophomore and junior years, on earth processes, materials, observations, and history. Majors also take introductory courses in mathematics, chemistry, and in many cases, physics and biology. The selection of(More)
Although therapeutic treatment strategies appear promising for retarding the progression of HIV-related diseases, prevention remains the most effective strategy against the HIV/AIDS epidemic. This paper focuses on the effect of condom use as a single-strategy approach in HIV prevention in the absence of any treatment. There are two primary factors in the(More)
