In theories with a hidden ghost sector that couples to visible matter through gravity only, empty space can decay into ghosts and ordinary matter by graviton exchange. Perturbatively, such processes can be very slow provided that the gravity sector violates Lorentz invariance above some cut-off scale. Here, we investigate non-perturbative decay processes involving ghosts, such as the spontaneou...

A WebView is a web page that is automatically created from base data, which are usually drawn from a DBMS. A WebView can be either materialized as an html page at the web server, or virtual, always being computed on-the-fly. For the materialized case, updates to base data lead to immediate recomputation of the WebView, whereas in the virtual case, recomputation is done on demand with each reque...

The application of new technologies in health units suggests the materialization of an advanced Electronic Health Record as a central axis in medical information management. The aim of present study is to point out the position Information and Communications Technology has in the health field and how it can play a major role in the materialization of an advanced Electronic Health Record, offeri...

We present an in-memory, cross-platform, parallel reasoner for RDFS and RDFSPlus . Inferray uses carefully optimized hash-based join and sorting algorithms to perform parallel materialization. Designed to take advantage of the architecture of modern CPUs, Inferray exhibits a very good uses of cache and memory bandwidth. It offers state-of-theart performance on RDFS materialization, outperforms ...

The reasoning should tackle big data issues like other domains as the size of ontology grows bigger and bigger. Especially, rule-based reasoning should overcome the following challenges: duplicate elimination and rule matching efficiency. To deal with these challenges, we introduce a new rulebased reasoning method which materializes each generic instance rule into several schema-specific instan...

The source material for ectoplasm is primarily dissociated water from the medium's body. The hydrogen and oxygen ions are rearranged in a “framework of materialization” as a step toward completing the etheric structure of the intended molecules. Cellulose is suggested as a possible candidate for ectoplasm since over 70 percent of its atoms are the constituents of water. The missing carbon atoms...

this research study investigated the development of listening proficiency level by the aid of different media- tional artifacts in systemic theoretical instruction (sti). the study considered whether exposing learners to different types and various numbers of mediating artefacts would increase their awareness towards listen- ing concepts after two months, and consequently promote their listenin...

Current skyline evaluation techniques assume a fixed ordering on the attributes. However, dynamic preferences on nominal attributes are more realistic in known applications. In order to generate online response for any such preference issued by a user, one obvious solution is to enumerate all possible preferences and materialize all results of these preferences. However, the pre-processing and ...
