This important study shows that the Nora virus, a natural Drosophila pathogen that also persistently infects many laboratory fly stocks, infects intestinal stem cells (ISCs), leading to a shorter life ...

THE detail seen in a highly magnified electron micrograph is to-day limited more by a lack of contrast in the image than by any lack of resolution in the microscope, which is now usually capable ...

Abstract: This paper presents an absolute capacitive rotary encoder using a sample-and-hold demodulator (SHD) to reduce interference between sine and cosine channels. The capacitive encoder measures ...

Additionally, we propose a Resnet Pyramid Hierarchical Feature Extractor (RPHFE) based on down and up sample resize pairs to endow decoded images with richer multi-scale features. We term the ...

Doctors in China inadvertently took time-series images of parasitic worms actively invading a woman's brain and causing rare and rapidly progressing lesions. The previously healthy 60-year-old ...

which may be subject to interference by illumination artifacts. In particular, the so-called vignetting artifact—the decrease of image intensity toward the edges of an image—is, at the moment, widely ...

Neurons were visualised with an infrared differential interference contrast (DIC) microscope using a 40x water-immersion ... ± S.E.M. Statistical comparisons were performed using one-sample two- ...

Methods: We developed a novel method to analyze stacks of confocal fluorescence images of single cells ... each individual particle. Electron microscopy: sample preparation is considerably easier.

You could infer things about them using X-ray crystallography or measure their pull on tiny probes using atomic force microscopes, but not take a direct image ... strike the sample travel at ...
