extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

Temperature Dependence of η and η ′ Masses

We investigate the temperature dependence of η and η′ masses due to scatterings from thermal pions in a heat bath using the non-linear sigma model. We show that mass shifts of η and η′ and the shift in the mixing angle are negligible.

Leon Chesley (1908-2000)

Leon Chesley studied hypertension, or high blood pressure, in pregnant women during the mid-twentieth century. Chesley studied preeclampsia and eclampsia, two hypertensive disorders found in approximately five percent of all US pregnancies. In New Jersey and New York, Chesley devoted over forty years to researching preeclampsia and eclampsia, and conducted several long-term studies using the sa...

The decay η ′ c → η

The decay η ′ c → η c π π. Abstract It is pointed out that the decay of the recently observed charmonium η ′ c resonance, η ′ c → η c π π is simply related to the well studied decay ψ ′ → J/ψ π π and can thus be used for absolute normalization of other decay modes of the η ′ c. The total rate of the discussed decay should be approximately three to four times the corresponding rate for the ψ ′ r...

1908 Scheme I + - CHOC

A synthetic strategy for the preparation of the quinone antibiotic naphthyridinomycin is outlined. An efficient synthesis of key tricyclic intermediate 6 is described. Naphthyridinomycin (I) is an architecturally interesting broad spectrum antibiotic produced by Streptomyces lusitanus. 9 1 2 The structure elucidation of 1 in I974ia,b revealed its unique hexacyclic structure which shared a quino...
