Complex Gradient Systems [PDF]
, 2012 Let $M$ be a complex manifold of complex dimension $n+k$. We say that the functions $u_1,...s,u_k$ and the vector fields $ _1,..., _k$ on $M$ form a \emph{complex gradient system} if $ _1,..., _k,J _1,...,J _k$ are linearly independent at each point $p\in M$ and generate an integrable distribution of $TM$ of dimension $2k$ and $du_ ( _ )=0$, $\

The complexity of anatomical systems [PDF]
Theoretical Biology and Medical Modelling, 2005 AbstractBackgroundThe conception ofanatomical entitiesas a hierarchy of infinitely graduated forms and the increase in the number of observed anatomical sub-entities and structural variables has generated a growingcomplexity, thus highlighting new properties of organised biological matter.Results(1) Complexity is so pervasive in the anatomical world ...

Robust enhancement of high harmonic generation via attosecond control of ionization [PDF]
EPJ Web of Conferences, 2019 We demonstrate up to two orders of magnitude enhancements in high harmonic generation efficiency via sub-cycle control and scaling of the ionization rate in a two colour laser field.

A COVID-19 vaccination model for Aotearoa New Zealand
Scientific Reports, 2022 We develop a mathematical model to estimate the effect of New Zealand’s vaccine rollout on the potential spread and health impacts of COVID-19. The main purpose of this study is to provide a basis for policy advice on border restrictions and control ...

Editorial: Ecological complex systems [PDF]
The European Physical Journal B, 2008 Main aim of this topical issue is to report recent advances in noisy nonequilibrium processes useful to describe the dynamics of ecological systems and to address the mechanisms of spatio-temporal pattern formation in ecology both from the experimental and theoretical points of view.

, 2004 What features characterise complex system dynamics? Power laws and scale invariance of fluctuations are often taken as the hallmarks of complexity, drawing on analogies with equilibrium critical phenomena[1-3]. Here we argue that slow, directed dynamics,
