Positive geometries and canonical forms
Journal of High Energy Physics, 2017 Recent years have seen a surprising connection between the physics of scattering amplitudes and a class of mathematical objects — the positive Grassmannian, positive loop Grassmannians, tree and loop Amplituhedra — which have been loosely referred to as “

FEBS Open Bio, EarlyView.We provide a step‐by‐step guide for producing E140 antigen fragments from Plasmodium berghei (Pb1) and Plasmodium vivax (Pv1). Pb1/Pv1 are expressed in E. coli, solubilized by freeze–thawing, refolded by slow dilution, purified by affinity chromatography (IMAC), then concentrated and subjected to quality control.

Cartan’s Approach to Second Order Ordinary Differential Equations [PDF]
, 2020 In his work on projective connections, Cartan discusses his theory of second order differential equations. It is the aim here to look at how a normal projective connection can be constructed and how it relates to the geometry of a single second order ...

Mapping Hsp104 interactions using cross‐linking mass spectrometry
FEBS Open Bio, EarlyView.This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

Integration-by-parts identities and differential equations for parametrised Feynman integrals
Journal of High Energy PhysicsIntegration-by-parts (IBP) identities and differential equations are the primary modern tools for the evaluation of high-order Feynman integrals. They are commonly derived and implemented in the momentum-space representation.

Causal geometries and third-order ordinary differential equations [PDF]
, 2009 We discuss contact invariant structures on the space of solutions of a third-order ordinary differential equation. Associated to any third-order differential equation modulo contact transformations, Chern introduced a degenerate conformal Lorentzian ...

On some interpretation of linear frames in projective differential geometry
Дифференциальная геометрия многообразий фигур, 2018 The centroprojective group, i. e. the stabilizer G of a fixed point A in the group GP(n) of projective transformations of n-dimensional projective space Pn (n > 1) is considered in the paper. Two faithful representations of the linear quotient group of G
