We propose a Web service architecture for achieving bidirectional updating. This architecture consists of three tiers: clients, a Bi-X bidirectional transformation engine, and some content servers accessible through the Internet. The benefit of using this architecture is that users can harness the power of bidirectional transformations without the burden of installing and maintaining the bidire...

Bidirectional promoters are regulatory regions co-regulating the expression of two neighbouring genes organized in a head-to-head orientation. In recent years, these regulatory regions have been studied in many organisms; however, no investigation to date has been done to analyse the genetic variation of the activity of this type of promoter regions. In our study, we conducted an investigation ...

We present an intuitive explanation for the limited effectiveness of front-to-end bidirectional heuristic search, supported with extensive evidence from many commonly-studied domains. While previous work has proved the limitations of specific algorithms, we show that any front-to-end bidirectional heuristic search algorithm will likely be dominated by unidirectional heuristic search or bidirect...

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...

the prophet’s political activities in medina indicate a particular kind of power exercise in the public domain. on the other hand, after receiving shari’a, he promulgated it and enforced the related verdicts and teachings among people. realization of these two facts in his behavior turns the relationship between power exercise by him and islamic shari’a into a basic question. the relationship b...

objective(s): phospholipase c ζ (plcζ) is considered as a nominee for sperm associated oocyte activating factors and is located back-to-back with capza3, an actin-capping protein controlling actin polymerization during spermiogenesis. they contain a common bidirectional promoter. the objective of this study was to identify individuals with parallel low expression of plcζ and capza3 mrna, in hop...

In this paper, we discuss parallel implementation of an artificial neural network for pattern d a t i o n , the Bidirectional Associative Memory(BAM). Transputer-based parallel architecture8 like hypercube, mesh and linear array are used to exploit the parallelism in BAM. A comparitive study of utilization and speedup for various architectures is made. Hypercube performs better in terms of util...

Bidirectional Texture Functions (BTFs) provide a realistic depiction of the appearance of many real-world materials as they contain the spatially varying light scattering behavior of the material surface. Since editing of existing BTF data is still in its early stages, materials have to be measured from real-world samples. In contrast to the related Spatially Varying BRDFs (SVBRDFs), the reflec...

In pursuit of photorealistic rendering of surface material, Bidirectional Texture Function (BTF) has been used frequently in recent years. Its main drawback is its massive data size. To solve this, the Spatial Bidirectional Reflectance Function (SBRDF) techniques compress BTFs into reflectance model parameters. However, SBRDF cannot produce the self-shadowing and self-occlusion mesostructure ef...
