We compare different schemes for the treatment of heavy quark production in Deep-Inelastic Scattering (DIS). For fully-integrated quantities such as F2(x,Q ), we advocate the use of the General-Massive Variable-Flavor-Number (GM-VFN) scheme; we present some results showing the progress of a Next-to-Leading Order calculation in this scheme. For differential quantities, the Fixed-Flavor-Number (F...

Charm final states in deep inelastic scattering constitute ∼ 25% of the inclusive cross-section at small x as measured at HERA. These data can reveal important information on the charm and gluon structure of the nucleon if they are interpreted in a consistent perturbative QCD framework which is valid over the entire energy range from threshold to the high energy limit. We describe in detail how...

This paper describes experimental results obtained with the use of measurement reduction for statistical IC fault diagnosis. The reduction method used involves data pre-processing in a fashion consistent with a specific definition of parametric faults. The effects of this preprocessing are examined. 1 Introduction An integrated circuit test is specified by a combination of input and output sign...

Abstract Introduction National hip fracture audits share a common heritage in the work of Rikshöft and Standardised Audit Hip Fracture Europe. However, as more countries develop audit programmes these evolve to address local needs, divergence data they collect compromises their scope for learning from clinical, quality improvement other nations. Method In 2021 we compared all ten established na...

A homomorphic feedforward network (HFFN) for nonlinear adaptive filtering is introduced. This is achieved by a two-layer feedforward architecture with an exponential hidden layer and logarithmic preprocessing step. This way, the overall input-output relationship can be seen as a generalized Volterra model, or as a bank of homomorphic filters. Gradient-based learning for this architecture is int...

This paper recognizes the detection of vascular changes in retinal vessels. From the retinal vasculature, artery/vein classification is done. It classifies the types of graph nodes and assigns graph links for one of two labels. Finally for the classification of artery/vein (A/V), graph based labeling results with a set of intensity features are performed. For doing this, list of 30 features are...

Weather is certainly the most important factor over which man has no control, and hence it has created dominance on the success or the failure of agricultural enterprises. Most important efforts since long time have been on weather and rain forecasting. However, the unpredictable nature of rainfall has not changed. Meteorologists can neither solve nor evaluate the problem of effective rainfall ...
