Why STEM Not TEM?

The TEM The TEM has a similar optical configuration to an optical microscope. A flood beam of electrons illuminates a thin sample. The electron transmitted through the sample are projected onto a viewing screen or camera for observation (Figure 1). Samples must be thin (around 100 nm) and the beam energies must be high. Electrons may either pass through the sample without being scattered or may...

Transanal Endoscopic Microsurgery (TEM)

Transanal endoscopic microsurgery may be considered medically necessary for treatment of clinical T1 rectal adenocarcinomas than cannot be removed using other means of local excision and that meet all of the following criteria:  Located in the middle or upper part of the rectum  Well or moderately differentiated (G1 or G2)  Without lymphadenopathy or microscopic angiolymphatic invasion  Les...

TEM Video Compressive Sensing

One of the main limitations of imaging at high spatial and temporal resolution during in-situ TEM experiments is the frame rate of the camera being used to image the dynamic process. While the recent development of direct detectors has provided the hardware to achieve frame rates approaching 0.1ms, the cameras are expensive and must replace existing detectors. In this paper, we examine the use ...

Evolution of TEM-type enzymes: biochemical and genetic characterization of two new complex mutant TEM enzymes, TEM-151 and TEM-152, from a single patient.

Two clinical isolates of Escherichia coli, CF1179 and CF1295, were isolated from a patient hospitalized in the hematology unit of the University Hospital of Clermont-Ferrand, Clermont-Ferrand, France. They were resistant to penicillin-clavulanate combinations and to ceftazidime. The double-disk synergy test was positive only for isolate CF1179. Molecular comparison of the isolates showed that t...
