We explore the relation between resummation and explicit multi-loop calculations for QCD hard-scattering amplitudes. We describe how the factorization properties of amplitudes lead to the exponentiation of double and single poles at each order of perturbation theory. For these amplitudes, previously-observed relations between single and double poles in different 2 → 2 processes can now be inter...

Auctions are mechanisms that formalise the rules with which automated trading schemes can be conducted, and in this paper we model the interaction of bidder and seller agents in sequential computerised auctions. We study the outcome of strategies that a designated “special bidder” (SB) may follow in the presence of a collection of other bidders in an English auction, under the assumption that t...

In this paper, we focus on the objective prediction of two of the foreground perceptual quality elements of the Diagnostic Acceptability Measure (DAM) that of SB and SF and show that they are correlated with statistical characteristics of features extracted from a physiologically motivated cochlear model response. The work complements earlier work where two other DAM quality elements, SH and SL...

This paper presents a system for classifying disaster-related tweets. The focus is on Twitter data generated before, during, and after Hurricane Sandy, which impacted New York in the fall of 2012. We propose an annotation schema for identifying relevant tweets as well as the more fine-grained categories they represent, and develop feature-rich classifiers for relevance and fine-grained categori...

the use of temporary runoff and underground dried-up water courses has been implemented by managers in recentyears to compensate for water shortages in arid and semi-arid regions. one way to use this water is to set up anunderground sandy dam in front of such water courses; selecting a suitable water course is the most important issue ofsuch a purpose. in the present research, this matter was i...

ECR Spotlight is a series of interviews with early-career authors from selection papers published in Journal Experimental Biology and aims to promote not only the diversity researchers (ECRs) working experimental biology during our centenary year but also huge variety animals physiological systems that are essential for ‘comparative’ approach. Sandy Saunders an author on ‘ Activation respirator...

The distribution and abundance with respect to depth and type of substratum of 20 species of gastropods and four species of bivalves of economic importance were examined in the continental shelf of Jalisco and Colima, México. These species were taken with net trawls at depths from 24 to 83 m in August, 1988. Most individuals and species of gastropods were collected in stations with sandy silt s...

Sandy Dance and Zhi-Qiang Liu Department of Computer Science University of Melbourne Parkville, 3052, Australia [email protected] Abstract In this paper we present an image interpretation system using fuzzy belief measures. This system is based on a symbolic object-oriented image interpretation system (SOO-PIN) we developed previously. In many image analysis and understanding applications, obje...
