We consider the problem of characterizing the sets of externally and internally active elements in a matroid. The main result is a canonical decomposition of the set of elements of a matroid on a linearly ordered set into external and i...

The number of ghost states at each energy level in a non-unitary conformal field theory is encoded in the signature Nike Air Force 1 Low characters of the relevant Virasoro algebra highest weight representations. We give expressions for...

Necessary and sufficient conditions for the existence of a common solution to the Lyapunov equation for two stable complex matrices are derived. These conditions are applied to the cases when a common weak solution to the Lyapunov equat...

Lauten and Ray pointed out the case of metrics (of correct signature) which do not allow a gravitational field. The incompatibility between the field equations and the high symmetry imposed by the underlying four-parameter group of moti...

We report 2 isolates of Mycobacterium fortuitum from patients with pulmonary tuberculosis lesions hybridizing to IS6110 probe in restriction fragment length polymorphism (RFLP) typing. Results of Nike Air Yeezy polymerase chain reaction...

The work of the International Committee on the Nomenclature of Ocean Bottom Features, and that of various national groups, is described. A list of approved terms of deep-sea features and their definitions is given. In order to avoid con...

An N/D dispersion theory is developed which solves crossing symmetric Low equations. The method is used to generate crossing symmetric Air Max Thea Canada solutions to the Chew-Low model. We show why the technique originally proposed by...

This paper describes the safety facilities developed for the Nike Air Max 2013 Cheap Trans-Tokyo Bay Highway Tunnel, at present the longest underwater road tunnel in the world. In particular, the paper describes the safety equipment, ev...

This article introduces and advances the basic theory of “uniformly primary ideals” for commutative rings, a concept that imposes a certain boundedness condition on the usual notion of “primary ideal”. Characterizations of unifo...

A finite-difference technique is used to calculate the die swell of a Newtonian liquid emerging from a capillary at zero Reynolds number. There is semi-quantitative agreement with experimental results. The experimental die swell is 13·...
