previous research has identified the nominal group as the most distinctive feature of the research article title. in contrast, the findings reported in this paper suggest theme/rheme is the dominant structure in title text. theme/rheme structures order and tie nominal groups in titles. when a title starts with a methodological term the first position nominal group acts as a theme marker. thus, ...

In this paper we establish c-bit semi-external graph algorithms, – i.e., algorithms which need only a constant number c of bits per vertex in the internal memory. In this setting, we obtain new trade-offs between time and space for I/O efficient LTL model checking. First, we design a c-bit semi-external algorithm for depth-first search. To achieve a low internal memory consumption, we construct...

description of lactation curve were investigated using sine function, compare it with two functions (dijekstra and wood). the data contained 32233 dairy milk yield records from 93 first parity iranian holstein cows that had calving between aug. 2008 and jul. 2009. actual milk production per day and subsequently the actual production of each animal were available in the first lactation. lactatio...
