Generating functions of (partially-)massless higher-spin cubic interactions [PDF]

open access: yes, 2012
Generating functions encoding cubic interactions of (partially-)massless higher-spin fields are provided within the ambient-space formalism. They satisfy a system of higher-order partial differential equations that can be explicitly solved due to their ...

A High-Order Kernel Method for Diffusion and Reaction-Diffusion Equations on Surfaces [PDF]

open access: yes, 2012
In this paper we present a high-order kernel method for numerically solving diffusion and reaction-diffusion partial differential equations (PDEs) on smooth, closed surfaces embedded in $\mathbb{R}^d$. For two-dimensional surfaces embedded in $\mathbb{R}^

A Fast Algorithm for Parabolic PDE-based Inverse Problems Based on Laplace Transforms and Flexible Krylov Solvers [PDF]

open access: yes, 2015
We consider the problem of estimating parameters in large-scale weakly nonlinear inverse problems for which the underlying governing equations is a linear, time-dependent, parabolic partial differential equation.

Efficient Gluing of Numerical Continuation and a Multiple Solution Method for Elliptic PDEs

open access: yes, 2014
Numerical continuation calculations for ordinary differential equations (ODEs) are, by now, an established tool for bifurcation analysis in dynamical systems theory as well as across almost all natural and engineering sciences. Although several excellent

Solvable vector nonlinear Riemann problems, exact implicit solutions of dispersionless PDEs and wave breaking

open access: yes, 2010
We have recently solved the inverse spectral problem for integrable PDEs in arbitrary dimensions arising as commutation of multidimensional vector fields depending on a spectral parameter $\lambda$.

Path Integral Solution of Linear Second Order Partial Differential Equations I. The General Construction [PDF]

open access: yes, 2004
A path integral is presented that solves a general class of linear second order partial differential equations with Dirichlet/Neumann boundary conditions. Elementary kernels are constructed for both Dirichlet and Neumann boundary conditions.

Conformally invariant elliptic Liouville equation and its symmetry preserving discretization

open access: yes, 2017
The symmetry algebra of the real elliptic Liouville equation is an infinite-dimensional loop algebra with the simple Lie algebra $o(3,1)$ as its maximal finite-dimensional subalgebra.

Development of a Novel Synthetic Hydrogel Sealant for Effective Prevention of Liver Resection‐Associated Bile Leakage

open access: yesAdvanced Healthcare Materials, EarlyView.
A dual‐crosslinking poly(ethylene glycol) (PEG) hydrogel is presented that rapidly solidifies and progressively adheres to tissue, achieving durable sealing of bile leaks. In hepatectomy models, this system prevents postoperative complications more effectively than conventional sealants, highlighting its translational potential as a safe and efficient ...

Relating AdS$_6$ solutions in type IIB supergravity

open access: yes, 2019
In this note we show that the IIB supergravity solutions of the form AdS$_6\times M_4$ found by Apruzzi et al. are related to the local solutions found by D'Hoker et al. We also discuss how the global regular solutions found by D'Hoker et al.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...
