HIGH-ENERGY-DENSITY ELECTRON BEAM FROM INTERACTION OF TWO SUCCESSIVE LASER PULSES WITH SUBCRITICAL-DENSITY PLASMA

High-energy-density electron beam from interaction of two successive laser pulses with subcritical-density plasma

It is shown by particle-in-cell simulations that a narrow electron beam with high energy and charge density can be generated in a subcritical-density plasma by two consecutive laser pulses.Although the first laser pulse dissipates underwater treasures sunken medallion rapidly, the second pulse can propagate for a long distance in the thin wake chan

Maternal vaccination against RSV can substantially reduce childhood mortality in low-income and middle-income countries: A mathematical modeling study

Background: Respiratory syncytial virus (RSV) is a leading cause of childhood mortality in infants below 6 months of age.In low-income and middle-income countries (LMICs), the public health burden is substantial and resources are limited.It is critical to inform decision makers about effectiveness of new interventions.Methods: We developed a mathem
