An Introduction to Theoretical Chemistry

Introduction to computational molecular biology

واحدهای دستوری : فصل پنجم از کتاب introduction to theoretical linguistic (john lyons)

رساله حاضر ترجمه فصل پنجم از کتاب "مقدمه ای بر زبانشناسی نظری" اثر لاینز است . در این فصل سه واحد مختلف توصیف دستوری یعنی جمله، واژک [تکواژ] و واژه بررسی شده است . طبق اظهار بلومفیلد "جمله یک صورت زبانی مستقل است ، نه اینکه بوسیله هر گونه ساختمان دستوری در هر صورت زبانی بزرگتر گنجانیده شده باشد" . نکته اصلی تعریف وی را می توان به اختصار بصورت زیر بیان کرد: جمله بزرگترین واحد توصیف دستوری است که...

Phenolics: From Chemistry to Biology

In recent years, few classes of natural products have received as much attention as phenolics and polyphenols. This special issue of Molecules, “Phenolics and Polyphenolics”, is a remarkable confirmation of this trend. Several aspects related to phenolics chemistry, comprising the several classes, will be discussed. In addition, the increasing interest in phenolics’ biological activities is cov...

Introduction to Computational Biology Lecture # 17: RNA Structure from Sequence

In the previous lesson we presented a Stochastic Context Free Grammar model for prediction of RNA secondary structure from sequence. This model enables us to assign a probabily for every possible folding of a given RNA sequence. We will start this lecture with some comments about the relation between probabilities and energies. Then we will learn how to calculate the probabilities of structural...
