Drosophila mechanical nociceptors preferentially sense localized poking

open access: yeseLife, 2022
Mechanical nociception is an evolutionarily conserved sensory process required for the survival of living organisms. Previous studies have revealed much about the neural circuits and sensory molecules in mechanical nociception, but the cellular ...

Impact of controlled extensional flow during extrusion of PP, PVDF and LDPE

open access: yesPolímeros, 2022
The structure and properties of semi-crystalline polymers can be drastically tailored by extensional flows. In this work, polypropylene (PP), Polyvinylidene fluoride (PVDF) and Low Density Polyethylene (LDPE) were melt extruded through a sequence of ...

Dynamical magnetic anisotropy and quantum phase transitions in a vibrating spin-1 molecular junction

open access: yes, 2012
We study the electronic transport through a spin-1 molecule in which mechanical stretching produces a magnetic anisotropy. In this type of device, a vibron mode along the stretching axis will couple naturally to the molecular spin.
