The Colugo (Cynocephalus variegatus, Dermoptera): The Primates’ Gliding Sister?
(2002)Although a general agreement on the major groups of eutherian orders and their phylogenetic affiliations is emerging, the evolutionary affiliations among the members constituting these groups are still subject to debate. ... -
The construction of greedy SVP LLL algorithm
(2013)LLL algorithm is an algorithm used to compute the approximation of the shortest nonzero vector in a basis of lattice. Terms of reduction size and the exchanging process are the important steps in the LLL algorithm. In 1994, ... -
The Effects of Milling Degree and Type of Bag on Fungal Infection and Some Chemical Contents of Stored Milled Rice
(1997)The effects of milling degree and type of bag on fungal infection of stored milled rice were investigated together with some chemical contents (glucose, amylose, protein and total lipid contents), and changes in moisture ... -
