1 While current and emergent applications become more and more complex, most of existing security policies and models only consider a yes/no response to the access requests. Consequently, modelling, formalizing and implementing permissions, obligations and prohibitions do not cover the richness of all the possible scenarios. In fact, several applications have access rules with the recommendatio...

To tackle problems emerging with rapid growth of information networks in scale and complexity, bio-inspired selforganisation is a promising design principle for future networks. However, self-organising systems fall into local optima or converge slowly under some environmental conditions. This can make self-organising systems slow to adapt to environmental change, despite robustness against env...

The changing environment always questions the survival mechanism of life on earth. The plant being special in the sense of their sessile habit need to face many of these environmental fluctuations as they have a lesser escape option. To counter these adverse conditions, plants have developed efficient sensing, signaling, and response mechanism. Among them the role of phytohormones in the manage...

Policy-based systems rely on the separation of concerns, by implementing independently a software system and its associated security policy. XACML (eXtensible Access Control Markup Language) proposes a conceptual architecture and a policy language to reflect this ideal design of policy-based systems. However, while rights are well-captured by authorizations, duties, also called obligations, are...

the fact that no state may benefit from its wrongful act, be it either commission or omission, is a well established principle of international law which originates from the fundamental principle of good faith. when states conclude a dispute settlement agreement and accept to refer a dispute to an international arbitration or judicial proceedings under bilateral or multilateral treaties, they a...

Organic farming has become increasingly popular in the world. This is mostly attributed toescalating consumer concerns over the impacts of pesticides and chemical fertilizers on humanhealth as well as growing concerns over environmental pollution derived from modernagricultural practices, such as rising greenhouse gas emissions and water contaminations. Butdoes organic farming actually displace...
