In this paper we present the behavior of JPEG2000 coding scheme over noisy or congested communication channels and highlight the cost analysis aspect. Two error schemes are considered including bit errors and packet dropping effects. Two bit error methods are used, consisting of flipping or dropping the bits, and various packet sizes are put to the test of packet dropping. Extensive performance...

As an example of structure determination in the 3.5-4.5 A resolution range, crystal structures of the ATPase p97/VCP, consisting of an N-terminal domain followed by a tandem pair of ATPase domains (D1 and D2), are discussed. The structures were originally solved by molecular replacement with the high-resolution structure of the N-D1 fragment of p97/VCP, whereas the D2 domain was manually built ...

Quasi-Monte Carlo (QMC) points are a substitute for plain Monte (MC) that greatly improve integration accuracy under mild assumptions on the problem. Because QMC can give errors o(1/n) as $$n\rightarrow \infty $$ , and randomized versions attain root mean squared o(1/n), changing even one point change estimate by an amount much larger than error would have been worsen convergence rate. As resul...
