We present the three-loop result for soft anomalous dimension governing long-distance singularities of multileg gauge-theory scattering amplitudes massless partons. compute all contributing webs involving semi-infinite Wilson lines at three loops and obtain complete correction to dipole formula. find that nondipole corrections appear already colored partons, where is a constant without kinematic dependence. Kinematic dependence appears only through conformally invariant cross ratios four...

The soft anomalous dimension governs the infrared singularities of scattering amplitudes to all orders in perturbative quantum field theory, and is a crucial ingredient both formal phenomenological applications non-abelian gauge theories. It has recently been computed at three-loop order for massless partons by explicit evaluation relevant Feynman diagrams. In this paper, we show how same result can be obtained, up an overall numerical factor, using bootstrap procedure. We first give...

Human traits vary in part due to genetically-determined change of transcription factor (TF) binding affinity within gene regulatory regions. However, few trait-causal variants or mechanisms are known. Here we propose 1,960 as strong candidates for causally altering human traits. They were discovered by baal-nf which uses ChIP-sequencing data identify allelic imbalance at heterozygous sites (allele-specific sites; ASBs) affinity-concordant positions TF- and/or co-factor motifs. These...

Abstract Background Myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) is a common, long-term condition characterised by post-exertional malaise, often with that not significantly relieved rest. ME/CFS has no confirmed diagnostic test or effective treatment and we lack knowledge of its causes. Identification genes cellular processes whose disruption adds to risk necessary first step towards development therapy. Methods Here describe DecodeME, an ongoing study co-produced people...
