Rube Goldberg’s cartoons famously depict absurd, unreasonably complex machines invented by Professor Lucifer G. Butts to carry out simple tasks. Rube Goldberg machine has now become a byword for overly complicated machinery or bureaucracy of any kind. The specific structure of Goldberg’s original cartoons, however, is quite interesting. Beyond simply being complex, his machines are based on a p...

The Goldberg-Sachs theorem has been very useful in constructing algebraically special exact solutions of Einstein vacuum equation. Most of the physical meaningful vacuum exact solutions are algebraically special. We show that the Goldberg-Sachs theorem is not true in linearized gravity. This is a remarkable result, which gives light on the understanding of the physical meaning of the linearized...

Plagiocephaly is a common condition that affects infants. It can be broadly grouped into positional and non positional plagiocephaly Positional plagiocephaly frequently resolves without intervention. Non positional plagiocephaly resulting from craniosynostosis often requires surgical intervention. In this case report, we present a rare case of unilateral frontosphenoid craniosynostosis. We disc...

Singing karaokemakes most of us quickly realize how poorly we can carry a tune. Typically, when we’re confident enough to sing on stage, we’re deaf to the negative feedback. Recently, however, neuroscientist Jesse Goldberg at Cornell University, USA, discovered a brain region that listens and produces a chemical ‘booing’ when birds sing off key. Vikram Gadagkar and colleagues in the Goldberg la...

Fujishige proposed a polynomial-time maximum flow algorithm using maximum adjacency (MA) orderings. Computational results by Fujishige and Isotani showed that the algorithm was slower in practice than Goldberg and Tarjan’s algorithm. In this paper we propose an improved version of Fujishige’s algorithm using preflows. Our computational results show that the improved version is much faster than ...

the tissue in as viable a condition as possible and the overall rates of tyrosine loss are similar to those reported by other workers (Fulks et al., 1975; Libby & Goldberg, 1980). We do not know whether the proteolysis Seen in low-O2 incubations is the result of new proteolytic mechanisms Or whether existing mechanisms become deregulated. Fuks, R. M., Li, J. B. & Goldberg, A. L. (1975)J. Biol. ...
