We compute the effects of soft gluon resummation for the production of high mass systems in hadronic collisions. We carefully analyse the growth of the perturbative expansion coefficients of the resummation formula. We propose an expression consistent with the known leading and next-to-leading resummation results, in which the coefficients grow much less than factorially. We apply our formula t...

We present a new general algorithm for calculating arbitrary jet cross sections in arbitrary scattering processes to next-to-leading accuracy in perturbative QCD. The algorithm is based on the subtraction method. The key ingredients are new factorization formulae, called dipole formulae, which implement in a Lorentz covariant way both the usual soft and collinear approximations, smoothly interp...

The production of jets in low Q ep scattering (photoproduction) and in low Q ee scattering (γγ scattering) allows for testing perturbative QCD and for measuring the proton and photon structure functions. This requires exact theoretical predictions for oneand two-jet cross sections. We describe the theoretical formalism, giving sufficient details, for calculating the direct and resolved processe...

We recall the origin of angular ordering of soft parton emission in the region of small x and show that this coherent structure can be detected in associated distributions. For structure functions at small x and at fixed transverse momentum the angular ordering is masked because of the complete inclusive cancellations of collinear singularities for x → 0. Therefore, in this case the dependence ...

OBJECTIVE Pneumonectomy may be needed in exceptional cases in patients with early stage NSCLC, especially in stage IB. The aim of this study was to evaluate whether overall survival in stage IB (T2aN0M0) NSCLC patients is worse after pneumonectomy. METHODS Retrospective study of a series of pathological IB (pIB) patients who underwent either lobectomy or pneumonectomy between 2000 and 2011. T...

INTRODUCTION Studies have found women try to avoid pain more than men, accept it less, and fear it more. The role of operator gender on subject gender pain in a clinical setting needs further study. The purpose of this randomized, double-blind investigation was to evaluate operator gender and its influence on reported subject gender pain in maxillary anterior infiltrations. METHODS Two hundre...

The singlet contribution to the g1(x;Q) structure function is calculated in the double-logarithmic approximation of perturbative QCD in the region x 1. Double logarithmic contributions of the type ( s ln (1=x)) which are not included in the GLAP evolution equations are shown to give a power-like rise at small-x which is much stronger than the extrapolation of the GLAP expressions. The dominant ...

We study J/ψ photoproduction via fragmentation at next-to-leading order in the QCD-improved parton model, using the nonrelativistic factorization formalism proposed by Bodwin, Braaten, and Lepage. We consider direct and resolved photoproduction of prompt J/ψ mesons and χcJ mesons radiatively decaying to J/ψ+ γ, taking into account the formation of both color-singlet and color-octet cc̄ states. A...

Inflammatory processes have been identified as key mediators of ischemia-reperfusion injury in ST-segment elevation myocardial infarction (STEMI). They add damage to the myocardium and are associated with clinical adverse events (heart failure cardiovascular death) poor recovery. Colchicine is a well-known alkaloid potent anti-inflammatory properties. In proof-of-concept phase II trial, colchic...
