Model of Consecutive, Steady-State Underflow for Vertical Tailing Silos

open access: yesAdvances in Materials Science and Engineering, 2019
A continuous tailing discharge model is proposed for solving the problems of high fluctuation in underflow concentration and low, unstable actual discharge concentration in vertical tailing silos. On the basis of the mass balance equation, a mathematical

The Tail of the Telomere [PDF]

open access: yesJournal of the American Chemical Society, 2008
The structure of a higher-order G-quadruplex structure for human telomeric DNA is presented. The structure was determined by a novel integrated approach in which molecular dynamics simulations were used to produce a stable structure, from which specific experimentally accessible properties were predicted.

Tracking the tail [PDF]

open access: yesJournal for ImmunoTherapy of Cancer, 2020
Immune-checkpoint inhibitors have deeply changed the therapeutic landscape of advanced non-small cell lung cancer without actionable genomic alterations. Immune-checkpoint inhibitors have become standard front-line therapy, especially among patients with tumours expressing high levels of programmed death ligand-1; yet, many patients do not respond to ...

Telling tails [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
The N-methyl-d-aspartate (NMDA)-type glutamate receptor is one of three major classes of receptors for glutamate, the principle excitatory neurotransmitter in the central nervous system. It plays a key role in learning and in the formation of memories by acting as a “coincidence detector” that initiates changes in synaptic strength that lead to the ...

Morphogenesis of the T4 tail and tail fibers [PDF]

open access: yesVirology Journal, 2010
Remarkable progress has been made during the past ten years in elucidating the structure of the bacteriophage T4 tail by a combination of three-dimensional image reconstruction from electron micrographs and X-ray crystallography of the components. Partial and complete structures of nine out of twenty tail structural proteins have been determined by X ...
