A Minimal Groebner Basis for the Defining Ideals of Certain Affine Monomial CurvesNov 17 2004Nov 20 2004In this article we produce Groebner bases for the defining ideal of a monomial curve that corresponds to an almost arithmetic sequence of positive integers, correcting previous work of Sengupta,(2003).
Measurement of the Reaction $^{12}C(ν_μ,μ^-) X$ Near ThresholdOct 21 1994Oct 25 1994The reaction $^{12}C(\nu_\mu,\mu^-) X$ has been measured near threshold using a $\pi ^+$ decay-in-flight $\nu_\mu$ beam from the Los Alamos Meson Physics Facility and a massive liquid scintillator neutrino detector (LSND). In the energy region $123.7 ... More
