We re–investigate the question whether a light higgsino–like neutralino is a viable Dark Matter candidate. To this end we compute the dominant one–loop corrections to the masses of the higgsino–like states in the minimal Supersymmetric Standard Model (MSSM), due to loops involving heavy quarks and their superpartners. We also calculate analogous corrections to the couplings of higgsino–like neu...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...

The SPI spectrometer aboard of the INTEGRAL satellite has released a map of the ee annihilation emission line of unprecedented quality, showing that most of the photons arise from a region coinciding with the stellar bulge of the Milky Way. The impressive intensity (≃ 10 photon cm s) and morphology (round and wide) of the emission is begging an explanation. Different classes of astrophysical ob...

STUDY OBJECTIVES Previous studies have demonstrated that albino but not pigmented rats show acute increases in REM sleep following light-to-dark transitions. Light and dark have also been shown to have direct effects on NREM sleep and wakefulness in albino rats. Little is known, however, about the direct light-dark effects on sleep patterns in pigmented animals. The purpose of the present study...

the neuropharmacological effect of petroleum ether and ethyl acetate soluble fractions of ethanol extract of the rhizome of drynaria quercifolia j. smith were studied in mice by intraperitoneal administration. the tests used were determination of effect on duration of diazepam-induced sleep, determination of effect on nikethamide-induced toxicity, light-dark test and force swimming test. the du...

We investigated the variation of /l/ in a large speech corpus through forced alignment. The results demonstrated that there is a categorical distinction between dark and light /l/ in American English. /l/ in syllable onset is light, and /l/ in syllable coda is dark. Intervocalic /l/ can be either light or dark, depending on the stress of the vowels. There is a correlation between duration (the ...
