Security Patch Management: Share the Burden or Share the Damage?

P management is a crucial component of information security management. An important problem within this context from a vendor’s perspective is to determine how to release patches to fix vulnerabilities in its software. From a firm’s perspective, the issue is how to update vulnerable systems with available patches. In this paper, we develop a game-theoretic model to study the strategic interact...

To Share or Not to Share SHARE-it: Lessons Learnt

The purpose of this position paper is to discuss the authors’ reflections on the use of Assistive Technologies to support user’s autonomy to perform the necessary Activities of Daily Living (ADL). In special, we will address the use of Agent-based robotic services.

Conformal mappings preserving the Einstein tensor of Weyl manifolds

In this paper, we obtain a necessary and sufficient condition for a conformal mapping between two Weyl manifolds to preserve Einstein tensor. Then we prove that some basic curvature tensors of $W_n$ are preserved by such a conformal mapping if and only if the covector field of the mapping is locally a gradient. Also, we obtained the relation between the scalar curvatures of the Weyl manifolds r...

Share and share alike isn't always the rule in science.

To share or not to share is the question

Data sharing is increasingly becoming an essential component of clinical practice and biomedical research. The debate has shifted from whether or not to exchange data to how best to achieve optimal sharing. This raises new ethical and legal challenges, particularly with regard to consent and privacy. This article discusses recent developments in the formulation of best practice guidelines for d...
