We present a new method for storing sparse matrices as a block matrix-graph where the blocks are stored via a compact, row-ordered scheme. This combines the exibility of the graph structure with the high eeciency of the compact storage technique. The inner compact pattern also allows identiication of entries, which often leads to advantages with respect to memory and computing time. Using this ...

Plumbing is a new mechanism for interprocess communication in Plan 9, specifically the passing of messages between interactive programs as part of the user interface. Although plumbing shares some properties with familiar notions such as cut and paste, it offers a more general data exchange mechanism without imposing a particular user interface. The core of the plumbing system is a program call...

Uncertainty surrounding the nature and timing of future carbon regulations poses a fundamental and far-reaching financial risk for electric utilities and their ratepayers. Long-term resource planning provides a potential framework within which utilities can assess carbon regulatory risk and evaluate options for mitigating exposure to this risk through investments in energy efficiency and other ...

The Support Vector Machines (SVM) has been an important classification technique in both machine learning and statistics communities. The robust SVM is an improved version of the SVM so that the resulting classifier can be less sensitive to outliers. In many practical problems, it may be advantageous to use different weights for different types of misclassification. However, the existing RSVM t...

In this paper I argue that syntactic categories are not part of UG but are acquired during first language acquisition as a result of doubling effects. In short, it is argued that a semantic operator OpF can only be (re-)analysed as a formal feature (that may yield a functional projection) if the language input exhibits doubling effects with respect to F. After providing a theoretical motivation...

BACKGROUND In cost-utility analyses gain in health can be measured using health state utilities. Health state utilities can be elicited from members of the public or from patients. Utilities given by patients tend to be higher than utilities given by members of the public. This difference is often suggested to be explained by adaptation, but this has not yet been investigated in patients. Here,...

Rheumatologists and other interested professionals at the OMERACT II conference formed small groups to discuss whether it was sensible to use a generic health status instrument in musculoskeletal disease trials. These instruments promise the possibility of comparison of health status between disease states. However, data is lacking on validity of the current generation of instruments to support...

BACKGROUND Foreign utilities of the EQ-5D-3L (3-level version of the EuroQol-5 Dimension of health questionnaire) are not readily transferrable to economic evaluations conducted from a national perspective. It has been advised to avoid transferring mean utilities from one country to another without adjusting them; yet no such method exists. PURPOSE The present study aimed to develop a method ...

BACKGROUND To perform decision analyses that include stroke as one of the possible health states, the utilities of stroke states must be determined. We reviewed the literature to obtain estimates of the utility of stroke and explored the impact of the study population and the elicitation method. SUMMARY OF REVIEW We searched various databases for articles reporting empirical assessment of uti...
