Biadjoint scalars and associahedra from residues of generalized amplitudes

open access: yesJournal of High Energy Physics, 2023
In the Grassmannian formulation of the S-matrix for planar N $$ \mathcal{N} $$ = 4 Super Yang-Mills, N k−2 MHV scattering amplitudes for k negative and n − k positive helicity gluons can be expressed, by an application of the global residue theorem, as a

Partial Substitution of K by Na Alleviates Drought Stress and Increases Water Use Efficiency in Eucalyptus Species Seedlings

open access: yesFrontiers in Plant Science, 2021
Eucalyptus, the most widely planted tree genus worldwide, is frequently cultivated in soils with low water and nutrient availability. Sodium (Na) can substitute some physiological functions of potassium (K), directly influencing plants’ water status ...

The application of multiple metrics in deformable image registration for target volume delineation of breast tumor bed

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Background and purpose For postoperative breast cancer patients, deformable image registration (DIR) is challenged due to the large deformations and non‐correspondence caused by tumor resection and clip insertion. To deal with it, three metrics (fiducial‐, region‐, and intensity‐based) were jointly used in DIR algorithm for improved accuracy ...

The KK¯π decay of the f1(1285) and its nature as a K⁎K¯−cc molecule

open access: yesPhysics Letters B, 2015
We investigate the decay of f1(1285)→πKK¯ with the assumption that the f1(1285) is dynamically generated from the K⁎K¯−cc interaction. In addition to the tree level diagrams that proceed via f1(1285)→K⁎K¯−cc→πKK¯, we take into account also the final ...

Image quality comparisons of coil setups in 3T MRI for brain and head and neck radiotherapy simulations

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose MRI is increasingly used for brain and head and neck radiotherapy treatment planning due to its superior soft tissue contrast. Flexible array coils can be arranged to encompass treatment immobilization devices, which do not fit in diagnostic head/neck coils. Selecting a flexible coil arrangement to replace a diagnostic coil should rely
