The Majorana Collaboration is operating an array of high purity Ge detectors to search for
neutrinoless double-β decay in Ge 76. The Majorana Demonstrator comprises 44.1 kg of Ge …

Present-day hunter-gatherers (HGs) live in multilevel social groups essential to sustain a
population structure characterized by limited levels of within-band relatedness and inbreeding. …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti:sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics. …
