For me humor has always been the saving grace of the human condition and I always look for humor in the most unlikely places. I will never forget telling Joan Steitz and several others at a meeting when they were planning to have an RNA Society and Journal, “How can you have a Society based on a 2′ hydroxyl?”Well fortunately they did not take my advice and so was born the RNA journal. Its birth...

Virtually all countries report population and other data as urban or rural, but specific definitions vary greatly as to the geographic units used and how populous an urban place must be. Many countries recognize urban as including overflow and suburbs outside municipal limits, giving rise to additional definitions such as urbanized areas and metropolitan areas. This article discusses the US def...

In the human brain, the inferior temporal cortex contains areas that seem to respond selectively to particular types of visual stimuli, such as faces or animals. One such region—the parahippocampal place area, or PPA—responds most strongly to images of places instead of faces, but how this higher-order selectivity is achieved remains unclear. In a new study in PLoS Biology, Rajimehr et al. iden...

This paper explores the relationship between knowledge hierarchies and sociospatial ordering of world and, in doing so, to problematize ways we study understand consumption marketing outside West. By world, I refer scalar divisions that organize mobilize hierarchical perceptions world. Adopting a view scale as way knowing apprehending trace origins, uses effects three scales – Third World, non-...

Many space applications require robotic manipulators which have large workspace and are capable of precise motion. Micro-macro manipulators are considered as the best solution to this demand. Such systems consist of a long flexible arm and a short rigid arm. Kinematic redundancy and presence of unactuated flexible degrees of freedom, makes it difficult to control micro-macro manipulators. This ...

Let K be a number field, let S be a finite set of places of K containing the archimedean places and let μ, α1, α2, α3 be non–zero elements in K. Denote by OS the ring of S–integers in K and by O × S the group of S–units. Then the set of equivalence classes (namely, up to multiplication by S–units) of the solutions (x, y, z, ε1, ε2, ε3, ε) ∈ O S × (O× S ) 4 of the diophantine equation (X − α1E1Y...

Although it is no longer debatable that sedentary behaviors are an actual cause of many metabolic diseases, the physiology of physical inactivity has been poorly investigated for this purpose. Along with microgravity, the physiological adaptations to spaceflights require metabolic adaptations to physical inactivity, and that is exceedingly well-simulated during the ground-based microgravity bed...
