Spectrum allocation in cognitive radio networks using chaotic biogeography‐based optimisation
IET Networks, 2018 Cognitive radio networks are a promising technology for the improvement of the spectrum utilisation. The basic idea is to maximise the utilisation of the available spectrum by dynamically assigning available channels to secondary users.

Wavelet-based response spectrum compatible synthesis of accelerograms-Eurocode application (EC8) [PDF]
, 2009 An integrated approach for addressing the problem of synthesizing artificial seismic accelerograms compatible with a given displacement design/target spectrum is presented in conjunction with aseismic design applications. Initially, a stochastic dynamics

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Darwin's Rainbow: Evolutionary radiation and the spectrum of consciousness [PDF]
, 2006 Evolution is littered with paraphyletic convergences: many roads lead to functional Romes. We propose here another example - an equivalence class structure factoring the broad realm of possible realizations of the Baars Global Workspace consciousness ...

Lyapunov theorems for Banach spaces
, 1993 We present a spectral mapping theorem for semigroups on any Banach space $E$. From this, we obtain a characterization of exponential dichotomy for nonautonomous differential equations for $E$-valued functions.

The genetic basis of a rare flower color polymorphism in Mimulus lewisii provides insight into the repeatability of evolution. [PDF]
PLoS ONE, 2013 A long-standing question in evolutionary biology asks whether the genetic changes contributing to phenotypic evolution are predictable. Here, we identify a genetic change associated with segregating variation in flower color within a population of ...

Evolutionary Spectrum for Random Field and Missing Observations [PDF]
, 2012 There are innumerable situations where the data observed from a non-stationary random field are collected with missing values. In this work a consistent estimate of the evolutionary spectral density is given where some observations are randomly missing.

Evolutionary characterisation of lung adenocarcinoma morphology in TRACERx
Nature Medicine, 2023 Analyses of the TRACERx study unveil the relationship between tissue morphology, the underlying evolutionary genomic landscape, and clinical and anatomical relapse risk of lung adenocarcinomas.
