Weak-strong uniqueness for volume-preserving mean curvature flow [PDF]
In this note, we derive a stability and weak-strong uniqueness principle for volume-preserving mean curvature flow. The proof is based on a new notion of volume-preserving gradient flow calibrations, which is a natural extension of the concept in the case without volume preservation recently introduced by Fischer et al. [arXiv:2003.05478].

Functionally-fitted energy-preserving integrators for Poisson systems [PDF]
In this paper, a new class of energy-preserving integrators is proposed and analysed for Poisson systems by using functionally-fitted technology. The integrators exactly preserve energy and have arbitrarily high order. It is shown that the proposed approach allows us to obtain the energy-preserving methods derived in BIT 51 (2011) by Cohen and Hairer ...

pp-waves in 11-dimensions with extra supersymmetry [PDF]
The Killing spinor equations for pp-wave solutions of eleven dimensional supergravity are analysed and it is shown that there are solutions that preserve 18,20,22 and 24 supersymmetries, in addition to the generic solution preserving 16 supersymmetries and the Kowalski-Glikman solution preserving 32 supersymmetries.

New solutions in organ preservation
Over the last 20 years, a number of methods and solutions have been developed to preserve donor organs for transplantation. Collins et al first introduced the simple cold-storage technique to store and transport kidneys up to 30 hours. The development of the University of Wisconsin cold-storage solution (UW-CSS) in 1986 improved organ preservation and ...

Assessment of reagent effectiveness and preservation methods for equine faecal samples [PDF]
The aim of our study was to identify the most suitable flotation solution and effective preservation method for the examination of equine faeces samples using the FLOTAC technique. Samples from naturally infected horses were transported to the laboratory

Constraint-satisfying Krylov solvers for structure-preserving discretisations [PDF]
A key consideration in the development of numerical schemes for time-dependent partial differential equations (PDEs) is the ability to preserve certain properties of the continuum solution, such as associated conservation laws or other geometric structures of the solution.
