Abstract The NASA K2 mission, salvaged from the hardware failures of Kepler telescope, has continued Kepler’s planet-hunting success. It revealed nearly 500 transiting planets around ecliptic plane, many which are subject further study, and over 1000 additional candidates. Here we present results an ongoing project to follow-up statistically validate new planets, in particular identify promisin...

Using elementary graded automorphisms of polytopal algebras (essentially the coordinate rings of projective toric varieties) polyhedral versions of the group of elementary matrices and the Steinberg and Milnor groups are defined. They coincide with the usual K-theoretic groups in the special case when the polytope is a unit simplex and can be thought of as compact/polytopal substitutes for the ...

background: klebseilla pneumoniae causes urinary tract infections, nosocomial pneumonia and intra-abdominal infections. capsular antigens are considered to be the ultimate virulence determinants. among 77 capsular serotypes of k. pneumoniae, serotypes k1 and k2 are the most virulent ones in humans. objectives: we designed a pcr method for detection of capsular serotypes k1 and k2 of k. pneumoni...

A new near detector, SciBar, for the K2K long-baseline neutrino oscillation experiment was installed to improve the measurement of neutrino energy spectrum and to study neutrino interactions in the energy region around 1 GeV. SciBar is a ’fully active’ tracking detector with fine segmentation consisting of plastic scintillator bars. The detector was constructed in summer 2003 and is taking data...

BACKGROUND Vascular calcification is a major contributing factor to mortality in end stage renal disease (ESRD). Despite the efficacy of phosphate binders to improve hyperphosphatemia, data on vascular calcification are less clear. There seems to be a difference in attenuation or delay in progression between different binders. In this in vitro experiment we tested whether phosphate binders coul...

One of the most basic questions in knot theory remains unresolved: is crossing number additive under connected sum? In other words, does the equality c(K1♯K2) = c(K1) + c(K2) always hold, where c(K) denotes the crossing number of a knot K and K1♯K2 is the connected sum of two (oriented) knots K1 and K2? The inequality c(K1♯K2) ≤ c(K1) + c(K2) is trivial, but very little more is known in general...
