oEE We study the problem of quantization for distributed parameter estimation in large scale sensor networks. Assuming a Maximum Likelihood estimator at the fusion center, we show that the Fisher Information is maximized by a scoreD 2 function quantizer. This provides a tight bound on best possible MSE for any unbiased estimator. Furthermore, we Y. show that for a general convex metric, the opt...

Based on the recently solved three-dimensional structure of pterin-4a-carbinolamine dehydratase from rat/human liver the involvement of the proposed active-site residues Glu57, Asp60, His61, His62, Tyr69, His79, Arg87 and Asp88 was examined by site-directed mutagenesis. Most of the mutants showed reduced activity, and only the Glu57-->Ala mutant and the His61-->Ala, His62-->Ala double mutant we...

The oligomeric structure of bacteriophage T7 gene 4 helicase/primase proteins was investigated using protein cross-linking and high pressure gel-filtration chromatography. Studies were carried out with both 4A' and 4B proteins. 4A' is a M64L mutant of 4A which has similar helicase and primase activities as the wild-type mixture of 4A and 4B proteins (Patel, S. S., Rosenberg, A. H., Studier, F. ...

در پودر های شوینده معمولا جهت نرم سازی آب و کف کردن پودر به عنوان سازنده، علاوه از stpp از زئولیت a نیز استفاده می شود. بنابراین در این پروژه روشهای سنتز نانو کریستال های زئولیت a و روشهای خصوصیت سنجی آنها مورد مطالعه قرار گرفته است. همچنین کارآئی های این نوع زئولیت به عنوان سازنده در پودر شوینده لباس شوئی مورد بررسی قرار گرفت. که در نتیجه ی آن کارآئی خوبی برای آنها نسبت به زئولیت معمولی دریافت...

Mass analysis with islands of stability has been investigated with three linear quadrupole mass filters: two with 4% added hexapole fields constructed with equal diameter (quadrupole 4A) and unequal diameter (quadrupole 4B) rods, and a conventional round-rod quadrupole that has apparently been slightly damaged. Islands are formed by applying auxiliary quadrupole excitation. With the Mathieu par...
