Goat IgG specific for anti-human IgM (I0759; Sigma-Aldrich, Inc., St. Louis, MO, USA) was conjugated to polyacrylic acid functionalized UCPs [200 nm, NaYF4:Yb3+, Er 3+; Intelligent Material Solutions Inc. (IMS); Princeton, NJ, USA MS] according to previously described protocols at a...
would have liked and also have used it on mostly static subjects, but picking out a bird hopping between branches in a tree and getting the focus accurate was fast and pretty reliable. Much, much easier and faster with this lens than with the adapted Sigma 100-400mm that I was using ...
It's now more than a year since we published our last superzoom group test and despite the hype surrounding mirrorless system cameras such as Micro Four Thirds or the Sony NEX, and the fact that entry level DSLRs are becoming more and more affordable, su
60%. This gives a base exposure of f4 at 360° shutter angle at ISO800 (or f2.8 at 180°). In the past we then successively underexposed the scene by reducing the shutter angle and brought the images back to the same base exposure....
Such a water steam generator is used in the SIGMA 4 wind tunnel of the Institut Aérotechnique de Saint-Cyr, which is located in Saint-Cyr l'École near Paris, France (Brocard, 1962). This original hot-shot ejector device has been conceived by SNECMA-FRENZL. The water, constituting the...
PURPOSE:To test the operation of a delta sigma modulation type A/D converter with high accuracy by applying gate control to the output pulse of the delta sigma modulation type A/D converter and allowing a counter to count the pulse. CONSTITUTION:A timing control means 23 controls the timing ...
Measurements included: mean, standard deviation, peak-to-peak value, median, total hits, peak (area of most hits), and mean ± 1,2, and 3 sigma Eye Diagram Measurements Eye diagram display mode allows triggering on both negative-going and positive-going edges of a signal. Eye diagram ...
