The patency of infarct-related artery (IRA) is approximately 50-60% while the rate of reocclusion is approximately 5-20%.2,3 Rheumatic fever and streptococcal infection are still prevalent in developing countries, which results in high antistreptokinase (ASK) titer in patients who sustained a previous streptococcal Ahmed M.

Comparative sequence analyses of eukaryotic genes and genomic regions are beginning to provide a wealth of information that is directly relevant to human biology. Functional changes that set us apart from apes are identifiable, as are functional constraints in proteins and genomic elements that arose in our relatively distant phylogenetic past.

Every year, new graduates and project students make an appearance in the lab. Acquiring the skills necessary to become a researcher can be a long and painful process, and many of the hints that would help relieve the pain are not written in books. For instance, you can’t be a researcher without being able to ask questions, but this doesn’t come naturally to everyone. Once you get the knack, how...

Several types of ASK multiport homodyne receivers are investigated, and the impact of the phase noise and of the shot noise on these receivers is analyzed. The simplest structure is the conventional multiport receiver with a matched filter in each branch. This structure can tolerate AvT (Av is the laser linewidth and T is the bit duration) of several percent with a small power penalty (3.6 perc...
