Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

High-precision accounting for high-precision network services

2021 IEEE 22nd International Conference on High Performance Switching and Routing (HPSR), 2021
The networking landscape is expected to undergo profound changes over the coming years, with new applications emerging that depend on the ability of networks to provide high-precision services with stringent service-level guarantees. To enable and incentivize network providers to deploy and deliver such services will also require advances in the way ...

A high precision micropump

Journal of Physics E: Scientific Instruments, 1969
A pump which delivers from 0?01 to 0?65 ml fluid per beat at a frequency of 10-80 beats per min is described. Consecutive discharges agree within 1?5% of the average. Pumping is achieved by rhythmically compressing an elastic tube which has one-way valves at either end.
