Bidirectional transformations are useful to maintain consistency between source data and target data. So far, researchers have proposed several theories and tools for bidirectional transformations on tree structures. However, as far as we know, there is no widely-recognized theory for bidirectional transformations on graphs. In this paper, we propose an approach to constructing bidirectional gr...

the main purpose of the study is to examine the causal relationship between government revenues and expenditures of the jordan government over the period from 1990 to 2011 using granger causality and vecm tests methodology. which provides channels of causation between government revenues (gr) and government expenditures (ge).the empirical results show that bidirectional causality running betwee...

Bidirectional promoters, which show great application potential in genetic improvement of plants, have aroused great research interest recently. However, most bidirectional promoters were cloned individually in the studies of single genes. Here, we initiatively combined RNA-seq data and cDNA microarray data to discover the potential bidirectional promoters in rice genome. Based on the expressio...

Bidirectional model transformation is useful for maintaining consistency between two models, and has many potential applications in software development including model synchronization, round-trip engineering, and software evolution. Despite these attractive uses, the lack of a practical tool support for systematic development of well-behaved and efficient bidirectional model transformation pre...

A profile hidden Markov model (PHMM) is widely used in assigning protein sequences to protein families. In this model, the hidden states only depend on the previous hidden state and observations are independent given hidden states. In other words, in the PHMM, only the information of the left side of a hidden state is considered. However, it makes sense that considering the information of the b...

Bidirectional model transformation plays an important role in maintaining consistency between two models, and has many potential applications in software development, including model synchronization, round-trip engineering, software evolution, multiple-view software development, and reverse engineering. However, unclear bidirectional semantics, weak bidirectionalization method, and lack of syst...

In this paper we present two novel reflectance measurement procedures that requiresampling
