Tellurium purification: various techniques and limitations

Purification and in vitro antioxidant activities of tellurium-containing phycobiliproteins from tellurium-enriched Spirulina platensis

Tellurium-containing phycocyanin (Te-PC) and allophycocyanin (Te-APC), two organic tellurium (Te) species, were purified from tellurium-enriched Spirulina platensis by a fast protein liquid chromatographic method. It was found that the incorporation of Te into the peptides enhanced the antioxidant activities of both phycobiliproteins. With fractionation by ammonium sulfate precipitation and hyd...

Effectiveness and Limitations of Various Software Techniques for "Soft Error" Detection: A Comparative Study

This paper deals with different software based strategies allowing the on-line detection of bit flip errors arising in microprocessor-based digital architectures as the consequence of the interaction with radiation. Fault injection experiments put in evidence the detection capabilities and the limitations of each of the studied techniques. RELATED TOPICS: Radiation effects, fault tolerant syste...

Practical limitations in optical entanglement purification

Entanglement purification protocols play an important role in the distribution of entangled systems, which is necessary for various quantum information processing applications. We consider the effects of photo-detector efficiency and bandwidth, channel loss and mode-mismatch on the operation of an optical entanglement purification protocol. We derive necessary detector and modematching requirem...
