SlipS and FallS
Injuries associated with slips and falls continue to be a significant burden to society, both in terms of human suffering and economic losses. Fall accidents are the second leading cause of accidental death in the United States (after motor vehicle accidents), resulting in more than 25,000 fatalities in 2009 and accounting for nearly 9 million visits to the emergency department (National Safety...
متن کاملDepinning, front motion, and phase slips.
Pinning and depinning of fronts bounding spatially localized structures in the forced complex Ginzburg-Landau equation describing the 1:1 resonance is studied in one spatial dimension, focusing on regimes in which the structure grows via roll insertion instead of roll nucleation at either edge. The motion of the fronts is nonlocal but can be analyzed quantitatively near the depinning transition.
متن کاملThe polymerase slips and PIPO exists.
Plant viruses that contain plus-sensed single-stranded RNA genomes are highly abundant in nature. As the equivalents of large mRNAs, these viral genomes utilize a wide variety of gene expression strategies for the production of their encoded proteins. The potyviruses, which are among the most agriculturally important members in this category, contain a single large open reading frame (ORF) codi...
متن کاملThe leaks and slips of bioenergetic membranes.
Bioenergetic membranes use proton gradients to transduce energy. However, when the proton gradient is large 1) there is a passive leak of protons (and other ions) across these membranes, and 2) some proton pumps may fail to pump protons (a phenomenon known as slip). Leaks and slips may be an unavoidable consequence of membrane structure and cause significant wastage of free energy, but they may...

ytoplasmic structures are sites of active mammalian mRNA decay, according to Cougot et al. (page 31). The group had previously identified cytoplasmic foci that included two human mRNA decapping enzymes. They now add subunits of a deadenylase, exonuclease, and possible helicase to the list of proteins found at these sites. After inhibition of a 5 –3 exonuclease, poly(A) RNA accumulates at the sa...
