How round is a protein? Exploring protein structures for globularity using conformal mapping.
Frontiers in Molecular Biosciences, 2014 We present a new algorithm that automatically computes a measure of the geometric difference between the surface of a protein and a round sphere. The algorithm takes as input two triangulated genus zero surfaces representing the protein and the round ...

Scalar Invariants of surfaces in conformal 3-sphere via Minkowski spacetime
, 2016 For a surface in 3-sphere, by identifying the conformal round 3-sphere as the projectivized positive light cone in Minkowski 5-spacetime, we use the conformal Gauss map and the conformal transform to construct the associate homogeneous 4-surface in ...

Dual parametrization of generalized parton distributions in two equivalent representations [PDF]
, 2014 The dual parametrization and the Mellin-Barnes integral approach represent two frameworks for handling the double partial wave expansion of generalized parton distributions (GPDs) in the conformal partial waves and in the $t$-channel ${\rm SO}(3 ...

Deterministic chaos and fractal entropy scaling in Floquet conformal field theories
Physical review B, 2020 In this paper, we study 2d Floquet conformal field theory, where the external periodic driving is described by iterated logistic or tent maps. These maps are known to be typical examples of dynamical systems exhibiting the order-chaos transition, and we ...

Conformal perturbation theory for twisted fields [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 We investigate second order conformal perturbation theory for orbifolds of conformal field theories in two dimensions. To evaluate the necessary twisted sector correlation functions and their integrals, we map them from the sphere to its torus double ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

The Moebius geometry of Wintgen ideal submanifolds [PDF]
, 2014 Wintgen ideal submanifolds in space forms are those ones attaining equality pointwise in the so-called DDVV inequality which relates the scalar curvature, the mean curvature and the scalar normal curvature. They are Moebius invariant objects.

Quantitative recurrence properties for self-conformal sets [PDF]
Proceedings of the American Mathematical Society, 2019 In this paper we study the quantitative recurrence properties of self-conformal sets $X$ equipped with the map $T:X\to X$ induced by the left shift. In particular, given a function $\varphi:\mathbb{N}\to(0,\infty),$ we study the metric properties of the ...

On a conformal-mapping property [PDF]
Annales Polonici Mathematici, 1984 Let \(w=f(z)\) be a non-constant entire function of a complex variable z and let D be a non-empty simply connected domain where \(w=f(z)\) is univalent. Let \(A_ 1A_ 2A_ 3A_ 4\) be an arbitrary rectangle contained entirely in D whose sides are parallel to the real and imaginary axes on the z-plane.
