Precision laser frequency stabilization is an important part of modern optical metrology, with applications ranging from atomic clocks to fundamental tests of physics. However, the frequency stability of the ultrastable cavities used in these experiments is fundamentally limited by thermal noise in the mirrors of the cavity. The thermal noise causes the atoms that form the mirrors to move randomly

The upstream ends of global supply chains – where raw material extraction or production takes place – are often hotspots for severe sustainability issues such as deforestation, biodiversity loss and human rights violations. Companies are under growing scrutiny from regulators, investors and civil society to ensure upstream-end supply chain sustainability. Yet, companies typically lack visibility b

This short subject studies configurations of animation and live action in contemporary Swedish documentary film. While digitization has challenged the indexical image’s verifying function, animation has been elevated to the level of legitimate document. The epistemological boundaries of documentary film have consequently been expanded, and now include the inner worlds of social subjects. In Gömd (

Huvudhandledning. Översikt över de nationella minoriteterna, deras historia samt om hur filmen kan utgöra ett verktyg i undervisningen.

The paper presents novel studies on the electrical-to-thermal energy deposition to gas at different phases of a spark. The experiments utilized a 10.9 milliliter custom-built spark calorimeter. The energy transfer efficiencies across spark phases—breakdown+arc, and glow are quantified, emphasizing their importance in ensuring robust ignition. An AC capacitive ignition system was considered in the

»Music to me is… my work. I've landed in the best job in the world, where a core task is to discover new music, to learn its internal logic and aesthetics, who created it, and why. I'm a music researcher and have just returned from the island of Java in Indonesia with my research partner and husband Nils, where we've been visiting experimental musicians in Yogyakarta – artists we've now followed f

Since 2003, Kamikatsu in Japan has established a sustainable zero-waste practice that has achieved a recycling rate exceeding 80%. By exploring how the community has shaped itself around the zero-waste concept, this paper aims to enhance our understanding of zero waste in practice from a universal design perspective. Interviews and photo documentation were used to gather data.

In villages and cities across the Indonesian island of Java, hundreds of songbird competitions are held every week. In these competitions, members of one species of songbird compete each other, where the aesthetic qualities the song, including its rhythm, melody, timbre, and volume, are evaluated by a team of referees. First prizes are large cash awards and sometimes cars. Birdsong that incorporat
