Magnetoluminescence
Pulsar Wind Nebulae, Blazars, Gamma Ray Bursts and Magnetars all contain
regions where the electromagnetic energy density greatly exceeds the plasma
energy density. These sources exhibit dramatic flaring activity where the
electromagnetic energy distributed over large volumes, appears to be converted
efficiently into high energy particles and gamma-rays. We call this general
process magnetoluminescence. Global requirements on the underlying, extreme
particle acceleration processes are described and the likely importance of
relativistic beaming in enhancing the observed radiation from a flare is
emphasized. Recent research on fluid descriptions of unstable electromagnetic
configurations are summarized and progress on the associated kinetic
simulations that are needed to account for the acceleration and radiation is
discussed. Future observational, simulation and experimental opportunities are
briefly summarized.Comment: To appear in "Jets and Winds in Pulsar Wind Nebulae, Gamma-ray Bursts

Efficacy of computer-assisted management of respiratory failure in neonates
We modified an algorithm for mechanical ventilation of infants with respiratory distress syndrome to create an interactive user-friendly computer program. To determine the effectiveness of this computer program, we evaluated the correction of deranged arterial blood gases in three groups of neonates: group I, treated before the introduction of the computer into the nursery; group II, managed by pediatric residents with the guidance of the computer program; group III, treated after the introduction of the computer into the nursery but managed without consideration of the computer output. Arterial blood gas values improved more frequently in the neonates managed with computer consultation (group II, 65/75, 87%) than in both control groups (group I, 37/57, 65%, P less than .005; and group III, 46/63, 73%, P less than .05). Furthermore, increases in ventilatory support in the presence of normal arterial blood gas values occurred only in patients managed without computer guidance. In a teaching institution, more effective care of neonates with respiratory failure may be facilitated by computer-assisted management of mechanical ventilators
