Abstract This paper proposes an optimization scheme of the transportation assignment for the oil product secondary distribution. Firstly, for the multi-variety oil product a cost model of the secondary distribution system for the oil product is established. Then a transportation assignment scheme is designed with the table-manipulation method. Based on the proposed transportation assignment sch...

background: the phylogenetic location of chinese spirometra sparganum isolates remains unclear. the aim of this study was to explore the phylogenetic location of the spirometra sparganum isolates from china. methods: the 28s ribosomal dna (rdna) d1 sequences of 14 spirometra sparganum isolates collected from thirteen locations in china were analyzed by using neighbor-joining (nj), maximum parsi...

background: rna molecules play many important regulatory, catalytic and structuralroles in the cell, and rna secondary structure prediction with pseudoknots is one themost important problems in biology. an rna pseudoknot is an element of the rna secondary structure in which bases of a single-stranded loop pair with complementary basesoutside the loop. modeling these nested structures (pseudokno...

Error tolerant backbone resonance assignment is the cornerstone of the NMR structure determination process. Although a variety of assignment approaches have been developed, none works well on noisy automatically picked peaks. We have designed an integer linear programming (ILP) based assignment system (IPASS) for this purpose. In order to reduce size of the problem, IPASS employs probabilistic ...

Large multimedia files (such as high definition audio, video, images, etc.) are accessed by an enormous number of mobile users over the Internet. Therefore, the bandwidth demand for mobile Internet access is increasing exponentially. To answer users’ demand, carrier aggregation is proposed in LTE systems. In carrier aggregation, the best available one or more carrier components of each band mus...

One of the most essential connections among all assignment tasks is design. The design high-quality assignments critical to achieving successful homework outcomes. This study explores existing research on roles and highlights current state in China's primary secondary schools. In terms loads, content, formats, stratification, suggestions are made
