A basic fact about Cohen reals is that adding λ Cohen reals cannot produce more than λ of Cohen reals. More precisely, if 〈rα|α < λ〉 are λ-Cohen generic reals over V , then in V [〈rα|α < λ〉] there is no λ -Cohen generic real over V . But if instead of dealing with one universe V we consider two, then the above may no longer be true. The purpose of this paper is to produce models V1 ⊆ V2 such th...

Machine tool owners require knowledge of their machine’s capabilities, and the emphasis increases with areas of high accuracy manufacturing. An aspect of a machine’s capability is its geometric accuracy. International Standards and best-practice guides are available to aid understanding of the required measurements and to advise on how to perform them. However, there is an absence of any intell...

In recent years we have seen an explosion of markets for portable electronic devices such as PDAs, personal communicators and mobile phones. The size and complexity of applications, but also development constraints like getting the product to market on time make the use of high-level languages like Java necessary. Java 2 Micro Edition (J2ME) has emerged as a good solution for developing applica...

background: numerous studies used microarray gene expression data to extract metastasis-driving gene signatures for the prediction of breast cancer relapse. however, the accuracy and generality of the previously introduced biomarkers are not acceptable for reliable usage in independent datasets. this inadequacy is attributed to ignoring gene interactions by simple feature selection methods, due...
