The thixotropic properties of filamentous actin suspensions were examined by a step-function shearing protocol. Samples of purified filamentous actin were sheared at 0.2 sec-1 in a cone and plate rheometer. We noted a sharp stress overshoot upon the initiation of shear, indicative of a gel state, and a nearly instantaneous drop to zero stress upon cessation of shear. Stress-overshoot recovery w...

Previous research has shown that no country currently meets the basic needs of its residents at a level resource use could be sustainably extended to all people globally. Using doughnut-shaped ‘safe and just space’ framework, we analyse historical dynamics 11 social indicators 6 biophysical across more than 140 countries from 1992 2015. We find tend transgress boundaries faster they achieve thr...

Masked thresholds were measured with running- and frozen-noise maskers. The 5-kHz signal was 2 ms in duration. The masker was low-pass noise (20 Hz-10 kHz); its total duration was 300 ms. The overall level of the masker was 30, 50, or 70 dB SPL. The onset of the signal was delayed by 0, 3, 8, 18, 198, or 278 ms relative to the onset of the masker. In all frozen-noise measurements, the signal wa...
