The exact mechanism of action by which morphine induces immunosuppression has yet to be clearly determined. A direct mechanism of action is suggested to operate through(More)
— The optical characteristics of the first laser diodes fabricated from a single-InAs quantum-dot layer placed inside a strained InGaAs QW are described. The saturated modal gain for this novel laser active region is found to be 9–10 cm 01 in the ground state. Room temperature threshold current densities as low as 83 A/cm 2 for uncoated 1.24-m devices are(More)
