Bose–Einstein Condensation: A Mathematically Unsolved Problem

Gout an Unsolved Problem.

AT the recent International Conference on Rheumatic Diseases held at Bath a whole day was devoted to the subject of " Gout," but in spite of many interesting papers it must be confessed that no startlingly new contribution to our knowledge of this disease emerged from the discussion. There is no reason to doubt that gout is essentially a disease of metabolism, but in spite of the recent major a...

On the theory of BoseEinstein condensation of quasiparticles: on the possibility of condensation of ferromagnons at high temperatures

The Bose condensation of magnons in physical systems of finite size is considered for the case of ferromagnetic thin films. It is shown that in accordance with present-day experimental capabilities, which permit one to achieve densities of longwavelength spin excitations of ∼ 1018 – 1019 −3 , in such films, the formation of a coherent condensate of such quasiparticles begins at temperatures T ∼...

Cellulose Hydrolysis: An Unsolved Problem

As on today, almost whole world is dependent on fossil fuels as a source of energy. With increase in world’s population there are growing concerns about diminishing fossil fuel resources, global warming and environmental pollution; hence there is a need for search of renewable resources to bridge the gap between the supply and demand of energy and chemicals. In this respect for production of bi...

Chunking German: An Unsolved Problem

This paper describes a CoNLL-style chunk representation for the Tübingen Treebank of Written German, which assumes a flat chunk structure so that each word belongs to at most one chunk. For German, such a chunk definition causes problems in cases of complex prenominal modification. We introduce a flat annotation that can handle these structures via a stranded noun chunk.
