Higher Order Corrections in Perturbative Quantum Field Theory via Sector Decomposition [PDF]
, 2011 The calculation of higher order corrections in perturbative quantum field theories is a particularly important subject. Our current model for particle physics is the stan- dard model; a quantum field theory which has served to describe a huge amount ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Angular phase-space integrals with four denominators through Mellin-Barnes
Journal of High Energy PhysicsWe compute four-denominator angular phase-space integrals using the Mellin-Barnes (MB) technique in dimensional regularisation. Independent of the scattering process, an angular integral can be categorised based on the nature of the momenta appearing in ...

Probing large-order perturbative expansions in lattice gauge theories with fermions [PDF]
, 2019 Many perturbative expansions in quantum field theories are believed to be plagued by factorial divergences. This can be seen as a reflection of the fact that an all-order perturbative computation cannot give a complete description of the theory, as it

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Jet-veto resummation at N3LLp + NNLO in boson production processes
Journal of High Energy Physics, 2023 Vetoing energetic jet activity is a crucial tool for suppressing backgrounds and enabling new physics searches at the LHC, but the introduction of a veto scale can introduce large logarithms that may need to be resummed.

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

N3LO+N3LL QCD improved Higgs pair cross sections
Journal of High Energy Physics, 2023 We report a new calculation of the soft-gluon threshold resummation for the Higgs boson pair production in the dominant production mode — gluon-gluon fusion — up to the next-to-next-to-next-to-leading logarithmic (N3LL) accuracy.

On-shelļ methods for perturbative QCD [PDF]
, 2006 We present new on-shell techniques for the calculation of colour ordered helicity amplitudes in QCD. We review the methods of on-shell recursion and the MHV rules before applying them to tree-level processes within the Standard Model.

Advances in Bioengineering and Biomedical Science Research, 2022 The author became interested in geriatrics in early 2019, especially in regard to longevity. During the period of 2010-2013, he self-studied metabolism, endocrinology, chronic diseases, and food nutrition. In 2014, he applied topology concept and engineering finite element method to develop a mathematical model of metabolism. His collected big data of ~
