The Arctic Ocean Spices Up
The contemporary Arctic Ocean differs markedly from midlatitude, ice-free, and relatively warm oceans in the context of density-compensating temperature and salinity variations. These variations are invaluable tracers in the midlatitudes, revealing essential fundamental physical processes of the oceans, on scales from millimeters to thousands of kilometers. However, in the cold Arctic Ocean, te...
متن کاملCytoplasmic diffusion: molecular motors mix it up
Random motion within the cytoplasm gives rise to molecular diffusion; this motion is essential to many biological processes. However, in addition to thermal Brownian motion, the cytoplasm also undergoes constant agitation caused by the activity of molecular motors and other nonequilibrium cellular processes. Here, we discuss recent work that suggests this activity can give rise to cytoplasmic m...
متن کاملMultivariate delta check method for detecting specimen mix-up.
Among laboratory mistakes, "specimen mix-up" is the most frequent and the most serious. According to the Clinical Chemistry Laboratory Error Report of Toranomon Hospital, specimen mix-up was often detected when there were many large discrepancies between the results of a test and the results of a previous test. We present here a checking method to detect specimen mix-up. The method, which we ca...
متن کاملCaMKII and stress mix it up in mitochondria
CaMKII is a newly discovered resident of mitochondria in the heart. Mitochondrial CaMKII promotes poor outcomes after heart injury from a number of pathological conditions, including myocardial infarction (MI), ischemia reperfusion (IR), and stress from catecholamine stimulation. A study using the inhibitor of CaMKII, CaMKIIN, with expression delimited to myocardial mitochondria, indicates that...
متن کاملDoes the IdP Mix-Up attack really work?
This document briefly describes and analyses the IdP Mix-Up attack on OAuth 2.0, as described by Fett, Küsters and Schmitz. We suggest that a key assumption on which the attack depends is incorrect, and as a result the attack does not appear to be a genuine threat to the security of OAuth 2.0.
