The flat-spectrum radio-quasar 3C279 (z=0.536) is the most distant object detected at very high energy (VHE) γ-rays. It is thus an important beacon for the study of the interaction of the VHE γ-rays with the Extra-galactic Background Light (EBL). Previous observations by EGRET showed a highly variable flux that can differ up to a factor of 100. In this paper results from an observation campaign...

In this paper we examine the operationalityigenerality trade-off and how it affects performance of explanation-based learning systems. Experience with the ARMS learning apprentice system, presented in the form of an empirical performance analysis, illustrates both sides of the trade-off.

In this paper we propose a trainable method for extracting Chinese entity names and their relations. We view the entire problem as series of classification problems and employ memory-based learning (MBL) to resolve them. Preliminary results show that this method is efficient, flexible and promising to achieve better performance than other existing methods.

We revisit the SM2 protocol, which is widely used in Chinese commercial applications and by Chinese government agencies. Although it is by now standard practice for protocol designers to provide security proofs in widely accepted security models in order to assure protocol implementers of their security properties, the SM2 protocol does not have a proof of security. In this paper, we prove the ...

Many concepts require generalizing number. For example, concepts such as momentum and energy conservation apply to arbitrary numbers of physical objects, clearing the top of a desk can require an arbitrary number of object relocations, and setting a table involves an arbitrary number of guests. In addition. there is recent psychological evidence [Ahn87] that people can generalize number on the ...

In this paper I tested whether Contradictory Matrix with 40 Inventive Principles, the simplest instrument from the Theory of Inventive Problem Solving (TRIZ), is a useful approach to a real-life PCR scenario. The PCR challenge consisted of standardization of fluorescence melting curve measurements in Competitive Amplification of Differentially Melting Amplicons (CADMA) PCR for multiple targets....
