Ultrasound biomicroscopy(UBM) is a high-resolution ultrasound technique that allows noninvasive in vivo imaging of structural details of the anterior ocular segment at near light microscopic resolution and provides detailed assessment of anterior segment structures, including those obscured by normal anatomi...
WHAT DO POSITIVE NOA LAB RESULTS MEAN (PART II): CONSIDERATIONS WHEN ORDERING AND INTERPRETING TRANSMISSION ELECTRON MICROSCOPY (TEM) ANALYSES OF ROCK/SOIL AND AIR SAMPLESGeologists must exercise considerable caution in relying upon TEM analytical results for NOA samples produced by asbestos testing ...
If we take as a given that at low levels of prevalence and intensity “egg-negative schistosomiasis” exists, the real questions are: “What does this mean for such individuals and what are its implications for NTD programs?” Again, in part, the answers to those questions rest on a need ...
4K resolution is also simply called 4K, and what does the K mean? In the digital field, it is different from the kilo in the decimal system where 1k equals 1,000. It is a power of two (2^10), 1024, referring to binary measurement. To describe digital images, pixels are counting in...
a technology that allows you to view EVs in real time. As you can imagine, trying to visualize a still frame of a biologic that is nano-sized and very fragile is very hard, and trying to think about doing cryomicroscopy or other fluorescent technology to get to ...
these structures seem to have been figments generated by the low resolution of light microscopy. Instead, individual molecules (or at the most, short MreB oligomers) move along the inner surface of the cytoplasmic membrane, following independent, almost perfectly circular paths that are oriented perp...
Measuring the point spread function of a star (typically, full width at half maximum $0.6– 1.0 arc sec) provides a measure of the spatial resolution on the disk of Mars. [28] Spectra were acquired using a sequence of four scans (source, sky, sky, source) with an integration time of ...
in the grain refinement articleI linked to earlier.With a whole different orientation of atomic planes, the martensite cannot form through a short shift in the atoms, so the lath ends at the boundaries where the crystal structure changes direction, as shown in this high resolution transmission ...
Currently, many world-renowned research groups have high-resolution image acquisition equipment available to elucidate this problem, such as electron microscopes. These instruments allow the acquisition of images of the viruses, enabling to check if their physical structure is intact (with capsid) or ...
On February 18, 2020, Zhou, et al., reported the cryo-EM structure of the full-length human ACE2 at 2.9 Å resolution in complex with the amino acid transporter B0AT1 [21]. They found that the complex, which had open and closed conformations, was assembled as a dimer and the ACE2...
