We study how much private mineral owners capture geologically-driven advantages in well productivity through a higher royalty rate. Using proprietary data from nearly 1.8 million leases, we estimate that the six major shale plays generated $39 billion in private royalties in 2014. There is limited pass-through of resource abundance into royalty rates. A doubling of the ultimate recovery of the ...

Host-associated bacterial communities can function as an important line of defence against pathogens in animals and plants. Empirical evidence and theoretical predictions suggest that species-rich communities are more resistant to pathogen invasions. Yet, the underlying mechanisms are unclear. Here, we experimentally test how the underlying resource competition networks of resident bacterial co...

Due to the diversity of network technologies, network application programs, and user requirements, it is getting difficult to manage Quality of Service (QoS) for the network services. To address this difficulty, we propose a QoS management framework named Communication Service Concierge (CSC). CSC resolves the difficulty by using the Component Oriented Programming approach. CSC downloads compon...

Despite the fact that approximate computations have come to dominate many areas of computer science, the field of program transformations has focused almost exclusively on traditional semanticspreserving transformations that do not attempt to exploit the opportunity, available in many computations, to acceptably trade off accuracy for benefits such as increased performance and reduced resource ...

A mathematical model for the loop pipelining problem is presented. The model considers several parameters for optimization and supports any combination of resource and timing constraints. The unrolling degree of the loop is one of the variables explored by the model. By using Farey’s series, an optimal exploration of the unrolling degree is performed and optimal solutions not considered by othe...

The European Commission’s (EC) Directorate General for Translation, together with the EC’s Joint Research Centre, is making available a large translation memory (TM; i.e. sentences and their professionally produced translations) covering twenty-two official European Union (EU) languages and their 231 language pairs. Such a resource is typically used by translation professionals in combination w...

We introduce a new method for unsupervised knowledge-based word sense disambiguation (WSD) based on a resource that links two types of sense-aware lexical networks: one is induced from a corpus using distributional semantics, the other is manually constructed. The combination of two networks reduces the sparsity of sense representations used for WSD. We evaluate these enriched representations w...

The future of any population is children. Resource limited settings with a high prevalence of HIV infection notably also have an excessive burden of malnutrition. The advances in prevention of mother to child HIV transmission programmes have led to very effective combination antiretroviral regimens resulting in growing numbers of HIV exposed but uninfected children. The mortality of HIV exposed...

Multimedia applications communicating over a packet-switched network present new challenges to the current networking technology. One of them is Quality of Service (QoS) requirement. Due to the increasing dynamics of traac introduced by multimedia applications, dynamic and exible QoS (Quality of Service) control is needed to ensure both QoS satisfaction and resource eeciency. In this paper, we ...

The increasing complexity of today’s reactive embedded applications can rapidly result in reduced real-time capabilities of the underlying hard and software. As an example for this paper we’ll refer to the specific and growing demands on the severely resource constrained sensor nodes in sensor/actuator networks (SANet). While preemptive operating systems are one way to retain acceptable reactiv...
