Singularities of bi-Hamiltonian systems

We study the relationship between singularities of bi-Hamiltonian systems and algebraic properties of compatible Poisson brackets. As the main tool, we introduce the notion of linearization of a Poisson pencil. From the algebraic viewpoint, a linearized Poisson pencil can be understood as a Lie algebra with a fixed 2-cocycle. In terms of such linearizations, we give a criterion for non-degeneracy of singular points of bi-Hamiltonian systems and describe their types

Voluntary business engagement in climate change: A study of the ClimateWise Principles

There is an expectation that the insurance sector should be leading business efforts in responding to climate change due to their inherent exposure to increasing risks. However, insurance companies normally operate on a one year time horizon - underwriting risks through policies which change each year to reflect new knowledge of these risks. The ClimateWise principles is a voluntary initiative of the insurance sector that was launched in 2007 to provide a basis for insurance companies to engage with climate change risks. This paper introduces the ClimateWise initiative and explores progress made since its launch. The paper presents new knowledge on whether this voluntary initiative provides a useful structure for the insurance sector in responding to the challenge of climate change. It finds that while the insurance sector has engaged with climate change, there is much more to do and we welcome the recent changes to ClimateWise that more accurately reflect this. The paper concludes that ClimateWise has been a useful initiative for the insurance companies and as a potential benchmark for the sector it offers some value. However, ClimateWise has not provided a strong enough engagement across the sector to embed climate action into business decisions

Lying about the Valence of Affective Pictures: An fMRI Study

The neural correlates of lying about affective information were studied using a functional magnetic resonance imaging (fMRI) methodology. Specifically, 13 healthy right-handed Chinese men were instructed to lie about the valence, positive or negative, of pictures selected from the International Affective Picture System (IAPS) while their brain activity was scanned by a 3T Philip Achieva scanner. The key finding is that the neural activity associated with deception is valence-related. Comparing to telling the truth, deception about the valence of the affectively positive pictures was associated with activity in the inferior frontal, cingulate, inferior parietal, precuneus, and middle temporal regions. Lying about the valence of the affectively negative pictures, on the other hand, was associated with activity in the orbital and medial frontal regions. While a clear valence-related effect on deception was observed, common neural regions were also recruited for the process of deception about the valence of the affective pictures. These regions included the lateral prefrontal and inferior parietal regions. Activity in these regions has been widely reported in fMRI studies on deception using affectively-neutral stimuli. The findings of this study reveal the effect of valence on the neural activity associated with deception. Furthermore, the data also help to illustrate the complexity of the neural mechanisms underlying deception

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
