The changes in power requirements and muscle efficiency during elevated force production in the fruit fly Drosophila melanogaster [PDF]

open access: yes, 1997
The limits of flight performance have been estimated in tethered Drosophila melanogaster by modulating power requirements in a 'virtual reality' flight arena.

Dissipation in ultra-thin current-carrying superconducting bridges; evidence for quantum tunneling of Pearl vortices

open access: yes, 2005
We have made current-voltage (IV) measurements of artificially layered high-$T_c$ thin-film bridges. Scanning SQUID microscopy of these films provides values for the Pearl lengths $\Lambda$ that exceed the bridge width, and shows that the current ...

Controlo da dispneia: estratégias, farmacológicas e não farmacológicas, para o seu alívio num contexto de cuidados paliativos: revisão sistemática da literatura [PDF]

open access: yes, 2012
PROBLEMÁTICA: A dispneia é um dos sintomas mais desestabilizadores e frequentes em pacientes com doença crónica, progressiva e incurável nos seus estádios mais avançados, aumentando de prevalência e intensidade ao longo das últimas semanas de vida do ...

Transition to Long Range Magnetic Order in the Highly Frustrated Insulating Pyrochlore Antiferromagnet Gd_2Ti_2O_7

open access: yes, 1999
Experimental evidence from measurements of the a.c. and d.c. susceptibility, and heat capacity data show that the pyrochlore structure oxide, Gd_2Ti_2O_7, exhibits short range order that starts developing at 30K, as well as long range magnetic order at ...
