New biosensors and transgenic mice for multiplex cGMP imaging
British Journal of Pharmacology, EarlyView.Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Of hired guns and ideologues: Why would a law firm ever retain an honest expert witness?
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract Suppose that expert witnesses appearing in litigation are, generically, either honest in their assessment of a fact situation or are advocates who testify in favour of their retaining party, regardless of new information. The type of a witness is known to law firms, who engage with them repeatedly, but not to courts.

Neural Local Inter‐reflection Modeling for Garment Fold Rendering
Computer Graphics Forum, EarlyView.Abstract Realistic garment rendering requires simulating complex multi‐bounce light paths within intricate fold geometries. In these regions, conventional path tracing is computationally expensive as light becomes trapped, necessitating high bounce counts for convergence.

Affinification: A Fine Approximation of Deformations
Computer Graphics Forum, EarlyView.Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.

Progressively Projected Newton's Method
Computer Graphics Forum, EarlyView.Abstract Newton's Method is widely used to find the solution of complex non‐linear simulation problems. To guarantee a descent direction, it is common practice to clamp the negative eigenvalues of each element Hessian prior to assembly—a strategy known as Projected Newton (PN)—but this perturbation often hinders convergence.

Lie Algebras and Lie Algebra Representations
, 2017In this chapter, we will introduce Lie algebras and Lie algebra representations, which provide a tractable linear construction that captures much of the behavior of Lie groups and Lie group representations.

On Contractions of Lie Algebras
Mathematics in Computer Science, 2016In this paper, the authors consider the notion of contraction of Lie algebras for the class of filiform Lie algebras, i.e. nilpotent Lie algebras with a maximal nilpotence index. This analysis is carried out using the notion of generalized derivations introduced in [\textit{P. Novotný} and \textit{J. Hrivnák}, J. Geom. Phys. 58, No.

Mathematics of the USSR-Sbornik, 1986
In this paper general problems of the deformations of Lie algebras over a field of characteristic zero and related problems of calculating the cohomologies with coefficients in the adjoint representation are considered. The author adapts and generalizes to the case of Lie algebras the general constructions of the cohomology theory of (local ...

Algebra, Lie Group and Lie Algebra
2010Geometry, algebra, and analysis are usually called the three main branches of mathematics. This chapter introduces some fundamental results in algebra that are mostly useful in systems and control. In section 4.1 some basic concepts of group and three homomorphism theorems are discussed. Ring and algebra are introduced briefly in section 4.2. As a tool,
