The Open Biomedical Ontologies (OBO) is a consortium that serves as a repository of ontologies that are structured like directed acyclic graphs. In this paper we present a language DQL for querying a database of directed acyclic graphs. The query language has a comprehension style syntax and contains a pattern specification sub-language DPL. DPL can be viewed as an extension of tree-pattern que...

The constitution of multi-level databases integrating, for example, both prosodic and morphosyntactic levels of representation presents a number of problems, some specific to the individual domains, and others concerning the integration of the two domains. It is argued that the formalism of annotation graphs provides an adequate solution to these problems, which can be implemented in an XML rep...

We employ the Deep Q-Learning algorithm with Experience Replay to train an agent capable of achieving a high-level of play in the L-Game while selflearning from low-dimensional states. We also employ variable batch size for training in order to mitigate the loss of the rare reward signal and significantly accelerate training. Despite the large action space due to the number of possible moves, t...

Awareness of application performance can be derived through various quantitative analyses, model-based and measurement-based approaches. A suitable visualization supports the understanding of application performance. Usually, analysis tools include a tool specific visualization or no visualization at all. In this paper we proposed to decouple the result visualization from the analysis approach....

This article proposes a downlink/uplink decoupled (DUDe) access scheme for cellular-enabled unmanned aerial vehicle (UAV) communication systems. To minimize interference, the proposed separates control and data links of UAVs, as well uplinks (ULs) downlinks (DLs) ground users (GUEs), onto different serving base stations operating frequencies. Since power availability is major constraint in UAV ...

State-of-the-art sensors of force, motion and magnetic fields have reached the sensitivity where quantum noise meter is significant or even dominant. In particular, best optomechanical devices has Standard Quantum Limit (SQL), which directly follows from Heisenberg uncertainty relation corresponds to balancing measurement imprecision perturbation probe by back action meter. The SQL not truly fu...

Ontologies are set to play a key role in the Semantic Web, and several web ontology languages, like DAML+OIL, are based on DLs. These not only provide a clear semantics to the ontology languages, but allows them to exploit DL systems in order to provide correct and complete reasoning services. Recent results shown that DL systems can be enriched by a conjunctive query language, providing a solu...

INTRODUCTION AND OBJECTIVE This study aims at answering what are the differences in socio-demographic status of patients with type 2 diabetes living in the city and the countryside and what is the impact of a place of residence on the level of metabolic control, the incidence of complications of diabetes and quality of life (QoL). MATERIALS AND METHODS 274 patients were divided into 2 groups:...
