We review the generalized vector dominance (GVD) approach to DIS at small values of the scaling variable, x. In particular, we concentrate on a recent formulation of GVD that explicitly incorporates the configuration of the γ * → q ¯ q transition and a QCD–inspired ansatz for the (q ¯ q)p scattering amplitude. The destructive interference, originally introduced in off-diagonal GVD is traced bac...

We provide a formulation of generalised vector dominance (GVD) for low– x deep-inelastic scattering that explicitly incorporates the γ * → q ¯ q transition and a QCD-inspired ansatz for the (q ¯ q)p forward-scattering amplitude. The destructive interference originally introduced in off-diagonal GVD is recovered in the present formulation and traced back to the generic structure of two-gluon-exc...

We apply our Yennie-Frautschi-Suura exponentiated cross section formulas for the parton processes q + (¯ q)′ → q ′′ + (¯ q)′′′ + n(G) to the process q + ¯ q → t + ¯ t + n(G) at FNAL energies, where G is a QCD gluon. We use semi-analytical methods to compute the ratio r exp = σ exp /σ B , where σ exp is our soft gluon YFS exponentiated cross section and σ B is the Born cross section. For m t = 0...

Effective initiatives for forest-based mitigation of climate change rely on continuous efforts to improve the estimation forest biomass. Allometric biomass models, which are nonlinear models that predict aboveground (AGB) as a function diameter at breast height (D) and tree (H), typically used in estimations. A combined variable D2H may be instead two separate predictors. The Q-ratio (i.e., rat...

The subcarrier signal to interference-plus-noise ratio expression for orthogonal frequency division multiplexing systems impaired by in-phase/quadrature (I/Q) imbalance is a ratio of correlated random variables. In its original form, a quadruple integral is required to evaluate the exact average subcarrier SINR which is cumbersome to compute numerically. We show that the quadruple integral can ...

Endocarditis is the major clinical manifestation of chronic Q fever. Although doxycycline along with hydroxychloroquine remains the mainstay of medical therapy for Q fever endocarditis, there are wide variations in the rapidity of the patient's decline of antibody levels during such therapy. We undertook a retrospective examination of whether there was any correlation between the ratio of serum...

INTRODUCTION: Landing is a common manoeuvre in sporting activities that can often lead to anterior cruciate ligament (ACL) injury with greater risk found in females [1]. Single-leg landing increases the risk of injury compared to double-leg landing because it is performed with less knee flexion and provides less stability. Although there has shown to be significant differences in maximum valgus...
