Large fluctuations of conductivity with time are observed in a low-mobility twodimensional electron system in silicon at low electron densities ns and temperatures. A dramatic increase of the noise power (∝ 1/fα) as ns is reduced below a certain density ng, and a sharp jump of α at ns ≈ ng, are attributed to the freezing of the electron glass at ns = ng. The data strongly suggest that glassy dy...

Export of Particulate Organic Carbon (POC) is mainly driven by gravitational sinking. Thus, traditionally, it thought that larger, faster-sinking particles make up most the POC export flux. H...

Blooms and coastal inundations of pelagic Sargassum have caused major problems to communities ecosystems throughout the tropical Atlantic over past decade. Understanding growth, movement, mortality is essential being able predict mitigate these events. In principle, cyclones that occur in this area could an impact on all three processes. a recent article, Sosa-Gutierrez et al. (2022, https://do...

Production, oxygen uptake, and sinking velocity of copepod fecal pellets egested by Temora longicornis were measured using a nanoflagellate (Rhodomonas sp.), a diatom (Thalassiosira weissflogii), or a coccolithophorid (Emiliania huxleyi) as food sources. Fecal pellet production varied between 0.8 pellets ind21 h21 and 3.8 pellets ind21 h21 and was significantly higher with T. weissflogii than w...

Cough is an important host-defense mechanism. The elderly and patients who are severely ill cannot cough effectively when lying in the supine position. Furthermore, pressure relieving air-mattresses are recommended for preventing the development of pressure ulcers. In this study, we clarified whether or not the cough peak flow (CPF), an index of cough strength, is affected by different firmness...

The implications are investigated of representing ocean gyre circulations by a diffusion term in the Stommel and Rooth box models of the thermohaline circulation (THC) in one and two hemispheres, respectively. The approach includes mostly analytical solution and study of the bifurcation structure, but also numerical integration and feedback analysis. Sufficient diffusion (gyre strength) elimina...
