PAPD5 is one of the seven members of the family of noncanonical poly(A) polymerases in human cells. PAPD5 was shown to polyadenylate aberrant pre-ribosomal RNAs in vivo, similar to degradation-mediating polyadenylation by the noncanonical poly(A) polymerase Trf4p in yeast. PAPD5 has been reported to be also involved in the uridylation-dependent degradation of histone mRNAs. To test whether PAPD...

حرکت در مسیرهای پیچیده و صعب العبور مسئله ایست که محققین علم رباتیک همواره به آن پرداخته اند. الهام از طبیعت و حرکت خزندگان راهگشای این دغدغه بوده است. در این پروژه علاوه بر پیاده سازی حرکت خزندگان، بینایی ماشین و بهینه سازی مسیر حرکت مد نظر قرار گرفته است. ابتدا یک ربات خزنده طراحی و ساخته شد. سپس بینایی ربات با استفاده از دوربینی که خارج از بدنه نصب گردید، تامین شد. در مرحله بعد تصاویر بدست...
