Medusan Morphospace: Phylogenetic Constraints, Biomechanical Solutions, and Ecological Consequences [PDF]

, 2008
Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world\u27s oceans, we argue that the primitive organization of cnidarian muscle tissue ...

#AlleredenvomWetter #FridaysforFuture #FFF

, 2019
Die Umsetzung zu diesem Poster kam meiner Tochter, als sie sich mal wieder mit der Schulpflicht auseinandersetzen musste, die das Engagement für die Klimapolitik bremst. Besonders ärgert sie in diesem Zusammenhang, dass nur über die Schulpflicht, statt über mögliche Umweltschutz Sofortmaßnahmen diskutiert wird.

Exposing and harvesting metadata using the OAI metadata harvesting protocol: A tutorial [PDF]

, 2001
In this article I outline the ideas behind the Open Archives Initiative metadata harvesting protocol (OAIMH), and attempt to clarify some common misconceptions. I then consider how the OAIMH protocol can be used to expose and harvest metadata.

Hestenes' Tetrad and Spin Connections

, 2007
Defining a spin connection is necessary for formulating Dirac's bispinor equation in a curved space-time. Hestenes has shown that a bispinor field is equivalent to an orthonormal tetrad of vector fields together with a complex scalar field. In this paper,

Pellet Printing for Soft Robotic Devices

Advanced Science, EarlyView.
Fused Granulate Fabrication (FGF) is established here as a reliable method for fabricating soft, airtight robotic devices. Through coordinated optimization of hardware, material selection, and process parameters, this approach enables high‐speed printing of thermoplastic elastomers with silicone‐like softness and modulus.
