Magnetoencephalography: From SQUIDs to neuroscience

a r t i c l e i n f o Magnetoencephalography (MEG), with its direct view to the cortex through the magnetically transparent skull, has developed from its conception in physics laboratories to a powerful tool of basic and clinical neu-roscience. MEG provides millisecond time resolution and allows real-time tracking of brain activation sequences during sensory processing, motor planning and actio...

18b. Gulf of Alaska Squids

Changes in assessment methodology: Assessment of squids is challenging due to a lack of reliable data and their unusual life history. In this document we suggest several alternatives for calculating ABC and OFL using the NPFMC’s tier system. Tier 5 requires reliable estimates of biomass and natural mortality rate (M). Under Tier 5, OFL is calculated as M * biomass, while ABC = 0.75 * M * biomas...

Homoclinic chaos in coupled SQUIDs

An rf superconducting quantum interference device (SQUID) consists of a superconducting ring interrupted by a Josephson junction (JJ). The induced supercurrents around the ring are determined by the JJ through the celebrated Josephson relations. We study the dynamics of a pair of parametrically-driven coupled SQUIDs lying on the same plane with their axes in parallel. The drive is through the a...
