Method for assessing the spatiotemporal resolution of structured illumination microscopy (SIM)
A method is proposed for assessing the temporal resolution of structured illumination microscopy (SIM), by tracking the amplitude of different spatial frequency components over time, and comparing them to a temporally-oscillating ground-truth. This method is used to gain insight into the performance limits of SIM, along with alternative reconstruction ...

Tandem GCIB-ToF-SIMS and GCIB-XPS analyses of the 2-mercaptobenzothiazole on brass
Surface analysis of 2-mercaptobenzothiazole (MBTH) adsorbed on brass from 3 wt.% NaCl solution was performed by means of X-ray photoelectron spectroscopy and tandem (MS/MS) time-of-flight secondary ion mass spectrometry (ToF-SIMS).

50nm-scale localization of single unmodified, isotopically enriched, proteins in cells. [PDF]
Imaging single proteins within cells is challenging if the possibility of artefacts due to tagging or to recognition by antibodies is to be avoided. It is generally believed that the biological properties of proteins remain unaltered when (14)N isotopes ...

Soil-structure interaction methods, SIM code. Volume III [PDF]
The Structure In Media (SIM) Code determines the response of a structure, embedded in soil/rock media, to a specified dynamic disturbance in the media. The structure is modeled as a series of lumped mass, elastic beams which may be interconnected with elastic springs. The disturbance in the free field is specified in terms of an accelerogram, the scale

Spiralling Inverse Method (SIM): A new inverse method to estimate ocean mixing
Ocean mixing affects the uptake, transport and storage of tracers such as heat and carbon in the ocean, subsequently impacting the climate and its future changes. Ocean mixing is caused by many different physical processes that take place on a large range of spatiotemporal scales.
