This paper fails to derive quantum mechanics from a few simple postulates. However, it gets very close, and does so without much exertion. More precisely, I obtain a representation of finite-dimensional probabilistic systems in terms of Euclidean Jordan algebras, in a strikingly easy way, from simple assumptions. This provides a framework within which real, complex and quaternionic QM can play ...

Limited observability is the assumption that economic agents can only observe a finite amount of information. Given this constraint, contracts among agents are necessarily finite and incomplete in comparison to the ideal complete contract that we model as infinite in detail. We consider the extent to which finite contracts can approximate the idealized complete contracts. The objectives of the ...

Left-right asymmetries in brains are usually minor or cryptic. We report brain asymmetries in the tiny, dorsal tubular nervous system of the ascidian tadpole larva, Ciona intestinalis. Chordate in body plan and development, the larva provides an outstanding example of brain asymmetry. Although early neural development is well studied, detailed cellular organization of the swimming larva's CNS r...

The ninth report of the European Society of Human Reproduction and Embryology Preimplantation Genetic Diagnosis Consortium is presented documenting cycles collected for the calendar year 2006 and follow-up of the pregnancies and babies born until October 2007, which resulted from these cycles. Since the beginning of the data collections there has been a steady increase in the number of cycles, ...

Immunoscreening of a C. paradoxa expression library against water soluble muroplast ("cyanelle") proteins resulted in isolation of a clone encoding the nucleus-encoded muroplast class-II fructose-1,6-bisphosphate aldolase (class-II FBA). Its nucleotide sequence was determined. The 1432 bp insert, derived from a single-copy gene transcript, bears a reading frame of 1206 bp in length, representin...

In the context of Hispanic teen smoking, this study examined the influence of pro-tobacco advertising and smoking warnings on teens from Hispanic communities. Analyzing data of two strata that had the highest percentage of urban (N = 1206) and non-urban (N = 385) Hispanic teenagers aged 13-17 from the 2012 National Youth Tobacco Survey, we found that pro-tobacco advertising indirectly influence...

An integrative environmental behavior model was applied in an online survey to investigate the determinants of intentions reduce personal air travel and corresponding perceived restrictions options among participants Switzerland (N = 1206). Flying habits emerged as most powerful predictor intentions, followed by prescriptive social norms, general attitudes, flight-specific acceptance justificat...
