We review the present data on high-energy, spin-dependent photoabsorption. We find a strong isotriplet term in (σA − σP ) which persists from Q2 ∼ 0.25GeV2 to high Q2 polarised deep inelastic scattering. For Q2 ∼ 4GeV2 and x between 0.01 and 0.12 the isotriplet part of g1 behaves as g (p−n) 1 ∼ x 1 2 , in contrast to soft Regge theory which predicts that g (p−n) 1 should converge as x → 0. The ...

The creation of massless scalar particles from the quantum vacuum by spherical shell with time varying radius is studied. In the general case of motion the equations are derived for the instantaneous basis expansion coefficients. The examples are considered when the mean number of particles can be explicitly evaluated in the adiabatic approximation.

Strong-field phenomena are a driving force behind the latest innovations in ultrafast science. As ultrafast laser sources improve in terms of peak pulse energy and wavelength tunability, applications that utilize high peak electromagnetic field strengths to generate attosecond pulses of both photons and electrons are becoming readily available. Furthermore, through the coupling of these optical...

2 Yichun Vocational Technical College, Yichun, 336000, P. R. China Abstract: A drink driving online control system based on photoelectric detection technology is introduced in the paper. The system can take the initiative to force motor vehicle drivers to test their drinking status, and reasonably control the driver’s behavior accordingly. The basic principle is to use the characteristic that 1...

We generalize the Einstein photoelectric equation for the case that the matter is irradiated by the polychromatic light of blackbody, or, by the synchrotron radiation. The work function of the collective motion of photoelectrons is discussed.

Dysgenic fertility means that there is a negative correlation between intelligence and number of children. Its presence during the last century has been demonstrated in several countries. We show here that there is dysgenic fertility in the world population quantified by a correlation of −0.73 between IQ and fertility across nations. It is estimated that the effect of this has been a decline in...
