Generation of crystal structures using known crystal structures as analogues
This analysis attempts to answer the question of whether similar molecules crystallize in a similar manner. An analysis of structures in the Cambridge Structural Database shows that the answer is yes - sometimes they do, particularly for single-component structures. However, one does need to define what we mean by similar in both cases. Building on this observation we then demonstrate how this ...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولSentence Fragments Regular Structures
This paper describes an analysis of telegraphic fragments as regular structures (not errors) handled by rn~n~nal extensions to a system designed for processing the s tandard language. The modular approach which has been implemented in the Unlsys natural language processing system PUNDIT is based on a division of labor in which syntax regulates the occurrence and distribution of elided elements,...
متن کاملGeneration From Lexical Conceptual Structures
This paper describes a system for generating natural language sentences from an interlingual representation, Lexical Conceptual Structure (LCS). This system has been developed as part of a Chinese-English Machine Translation system, however, it promises to be useful for many other MT language pairs. The generation system has also been used in CrossLanguage information retrieval research (Levow ...
متن کاملGeneration of Safety Case Argument-Fragments from Safety Contracts
Composable safety certification envisions reuse of safety case argument-fragments together with safety-relevant components in order to reduce the cost and time needed to achieve certification. The argumentfragments could cover safety aspects relevant for different contexts in which the component can be used. Creating argument-fragments for the out-of-context components is time-consuming and cur...
