In Bacillus subtilis, maturation of 5S rRNA is catalyzed by an enzyme called RNase M5. We searched for potential mRNA substrates for RNase M5 by gene array technology, based on the premise that most endonucleolytic cleavages have an effect on the stability of RNA and hence on steady-state levels of expression. Only a handful of genes had significantly altered expression in rnmV mutants compared...

M5 is a method developed by Quinlan [10] for inducing trees of linear regression models (model trees). The paper addresses the flexibility and optimality in M5 model tree by proposing two new algorithms, namely M5flex and M5opt. M5flex algorithm brings in domain knowledge by enabling the user to choose split attributes and split values for important nodes in a model tree so that the resulting m...

BACKGROUND Evidence-Based Medicine (EBM) is an important competency for the healthcare professional. Experimental evidence of EBM educational interventions from rigorous research studies is limited. The main objective of this study was to assess EBM learning (knowledge, attitudes and self-reported skills) in undergraduate medical students with a randomized controlled trial. METHODS The educat...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

A generalization of Nahm’s equation has been recently conjectured by Basu and Harvey to be the BPS condition describing the bound state of a stack of M2branes ending on an M5-brane. In this note exact solutions are presented for the proposed BPS equation – which is from the point of view of the M2-brane world-volume dynamics – with boundary conditions appropriate for M2-branes stretching betwee...
