Length-dependent disassembly maintains four different flagellar lengths in Giardia. [PDF]

, 2019
With eight flagella of four different lengths, the parasitic protist Giardia is an ideal model to evaluate flagellar assembly and length regulation. To determine how four different flagellar lengths are maintained, we used live-cell quantitative imaging ...

Signals controlling Cajal body assembly and function [PDF]

The International Journal of Biochemistry & Cell Biology, 2013
Cajal bodies (CBs) are subnuclear domains that participate in the biogenesis of small nuclear ribonucleoproteins (snRNPs) and telomerase. CBs are found in cells with high splicing demands, such as neuronal and cancer cells. The purpose of this review is to highlight what is known about the signals that impact the formation and activity of CBs ...

Dynamic simulations of many-body electrostatic self-assembly [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
Two experimental studies relating to electrostatic self-assembly have been the subject of dynamic computer simulations, where the consequences of changing the charge and the dielectric constant of the materials concerned have been explored. One series of calculations relates to experiments on the assembly of polymer particles that have been subjected ...

A Tolerance Specification Automatic Design Method for Screening Geometric Tolerance Types

Applied Sciences
At present, the automatic generation of tolerance types based on rule-based reasoning has an obvious characteristic: for the same assembly feature, tolerance items are recommended that satisfy all feature characteristics, with a large number of ...

Halo Assembly Bias in the Quasi-linear Regime

, 2007
We address the question of whether or not assembly bias arises in the absence of highly non-linear effects such as tidal stripping of halos near larger mass concentrations.
