Design and Research of 2-DOF Piezoelectric Nanopositioning Stage with Multiple Displacement Amplifiers and Decoupling Beams

Micromachines
A piezoelectric (PZT) nanopositioning stage with large stroke and low crosstalk is relatively appealing for microdisplacement operation. Rhombus and lever amplifiers are used to increase the overall displacement amplification ratio (DAR), and the ...

Value-driven simulation : thinking together through simulation in early engineering design

, 2017
The topic of ‘design for value’ has lately attracted a great deal of attention within the engineering design community. ‘Predicting’ the value of a future solution is however difficult, especially in early design phases.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

FEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Designing computer simulation experiments [PDF]

1988 Winter Simulation Conference Proceedings, 1988
This tutorial focuses on that part of a simulation study concerning setting the various specific model parameters and the experimental conditions under which the model will be exercised. Other issues in setting up and designing simulation experiments, such as variance reduction, ranking and selection, and optimization, are also mentioned.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.
