متن کاملThe Zonal Walker Circulation
In addition to the mean meridional Hadley circulation, there also exist zonal overturning circulations that contribute to the meteorology and climatology of the tropics. Together, these overturning circulations are commonly referred to as the Walker circulation. In this section, we first explore the history and basic structure of the Walker circulation. Later, we reintroduce the shallow water e...
متن کاملThe Marden-Walker syndrome.
The characteristic facies, joint contractures, muscular hypotonia, and growth and developmental delay of the Marden-Walker syndrome were present in a 19-month-old boy. Extensive evaluation of the neuromuscular system failed to identify a specific abnormality. Electromyography was normal with low amplitude. Light and electron microscopy of a skeletal muscle biopsy was normal. Histochemical study...
متن کاملMonomial Resolutions
Let M be a monomial ideal in the polynomial ring S = k[x1, . . . , xn] over a field k. We are interested in the problem, first posed by Kaplansky in the early 1960’s, of finding a minimal free resolution of S/M over S. The difficulty of this problem is reflected in the fact that the homology of arbitrary simplicial complexes can be encoded (via the Stanley-Reisner correspondence [BH,Ho,St]) int...
متن کاملResolutions of the Coulomb operator.
We discuss a generalization of the resolution of the identity by considering one-body resolutions of two-body operators, with particular emphasis on the Coulomb operator. We introduce a set of functions that are orthonormal with respect to 1r(12) and propose that the resulting "resolution of the Coulomb operator," r(12) (-1)=mid R:phi(i)phi(i)mid R:, may be useful for the treatment of large sys...
