Self-duality from twisted cohomology
Journal of High Energy PhysicsRecently a notion of self-duality for differential equations of maximal cuts was introduced, which states that there should be a basis in which the matrix for an ε-factorised differential equation is persymmetric.

Scattering forms and the positive geometry of kinematics, color and the worldsheet
Journal of High Energy Physics, 2018 The search for a theory of the S-Matrix over the past five decades has revealed surprising geometric structures underlying scattering amplitudes ranging from the string worldsheet to the amplituhedron, but these are all geometries in auxiliary spaces as ...

Algebraic singularities of scattering amplitudes from tropical geometry
Journal of High Energy Physics, 2021 We address the appearance of algebraic singularities in the symbol alphabet of scattering amplitudes in the context of planar N $$ \mathcal{N} $$ = 4 super Yang-Mills theory.

Advanced Theory and Simulations, EarlyView.This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

L-infinity algebras from multisymplectic geometry
, 2011 A manifold is multisymplectic, or more specifically n-plectic, if it is equipped with a closed nondegenerate differential form of degree n+1. In our previous work with Baez and Hoffnung, we described how the `higher analogs' of the algebraic and ...

Determination of the number of texture segments using wavelets
Electronic Journal of Differential Equations, 2001 This paper presents a robust method of determining the number of texture segments in an image. We take an $N imes N$ image and decompose it into $n imes n$ blocks.

Angewandte Chemie, EarlyView.At doping ratios ranging from 1 to 12 wt%, the BN‐S and BN‐Se‐based sensitizer‐free OLEDs exhibited nearly unchanged EL spectra with small FWHMs of 27–30 nm and EQEmax of 36.4–43.1%. The BN‐Se‐based OLED exhibited low efficiency roll‐off, with EQEs remaining at 36.7 and 31.8% at 100 and 1000 cd m−2, respectively, representing the best EL performance ...

An algebraic approach to minimal models in CFTs [PDF]
, 2017 CFTs are naturally defined on Riemann surfaces. The rational ones can be solved using methods from algebraic geometry. One particular feature is the covariance of the partition function under the mapping class group.

Mapping uncertainty using differentiable programming
AIChE Journal, EarlyView.Abstract Uncertainty quantification (UQ) and propagation is a ubiquitous challenge in science, permeating our field in a general fashion, and its importance cannot be overstated. Recently, the commoditization of differentiable programming, motivated by the development of machine learning, has allowed easier access to tools for evaluating derivatives of
