Abstract Conjugated fatty acids (CFAs) have been known for their anti-tumor activity. However, the mechanism of action remains unclear. Here, we identify CFAs as inducers of glutathione peroxidase 4 (GPX4) degradation through chaperone-mediated autop

Abstract In this paper, we introduce the momentum space amplituhedron for tree-level scattering amplitudes of ABJM theory. We demonstrate that the scattering amplitude can be identified as the canonical form on the space given by the product of posit

Abstract The story of positive geometry of massless scalar theories was pioneered in [1] in the context of bi-adjoint ϕ 3 theories. Further study proposed that the positive geometry for a generic massless scalar theory with polynomial interaction is

Abstract This article introduces a new approach to implement positivity for the 2-loop n-particle MHV amplituhedron, circumventing the conventional triangulation with respect to positive variables of each cell carved out by the sign flips. This appro

Abstract Recently, the accordiohedron in kinematic space was proposed as the positive geometry for planar tree-level scattering amplitudes in the ϕ p theory [1]. The scattering amplitudes are given as a weighted sum over canonical forms of some acco

Abstract We present new triangulations of the m = 4 amplituhedron relevant for scattering amplitudes in planar N $$ \mathcal{N} $$ = 4 super-Yang-Mills, obtained directly from the combinatorial definition of the geometry. Using the “sign flip” ch

Abstract In this paper, we consider the triangulation of the 2-loop MHV amplituhedron from “sign flip” definition. Using the isomorphism between the m = 2, k = 2 tree amplituhedron and the 1-loop MHV physical amplituhedron, we found the direct tr

Cryo-electron microscopy (cryo-EM) is an important experimental technique for the structural analysis of biomolecules that are difficult or impossible to crystallize. The three-dimensional structure of a biomolecule can be reconstructed using two-dim
