When lightning strikes twice.
The educational, occupational, and creative accomplishments of the profoundly gifted participants (IQs > 160) in the Study of Mathematically Precocious Youth (SMPY) are astounding, but are they representative of equally able 12-year-olds? Duke University’s Talent Identification Program (TIP) identified 259 young adolescents who were equally gifted. By age 40, their life accomplishments also wer...
متن کاملElectrical Injuries and Lightning Strikes
Electrical burn injuries account for about 5% of burns unit admissions. Electricians and linesmen are at highest risk but those working with electrical tools also form a significant proportion of this patient group. [2] Electrical injuries in children are unusual and are mainly due to misguided exploration outside the home. [3] For every death, there are two serious injuries and 36 reported ele...
متن کاملUltra - high energy cosmic rays may come from clustered sources
Clustering of cosmic-ray sources affects the flux observed beyond the cutoff imposed by the cosmic microwave background and may be important in interpreting the AGASA, Fly’s Eye, and HiRes data. The standard deviation, σ, in the predicted number, N , of events above 10 eV is σ/N = 0.9(r0/10Mpc) 0.9, where r0 is the unknown scale length of the correlation function (r0 ≃ 10 Mpc for field galaxies...
متن کاملExhumation of (ultra-)high-pressure terranes: concepts and mechanisms
The formation and exhumation of high and ultrahigh-pressure, (U)HP, rocks of crustal origin appears to be ubiquitous during Phanerozoic plate subduction and continental collision events. Exhumation of (U)HP material has been shown in some orogens to have occurred only once, during a single short-lived event; in other cases exhumation appears to have occurred multiple discrete times or during a ...
متن کاملUltra and Involution Ideals in $BCK$-algebras
In this paper, we define the notions of ultra and involution ideals in $BCK$-algebras. Then we get the relation among them and other ideals as (positive) implicative, associative, commutative and prime ideals. Specially, we show that in a bounded implicative $BCK$-algebra, any involution ideal is a positive implicative ideal and in a bounded positive implicative lower $BCK$-semilattice, the not...
