DPG-Based Time-Marching-Schemes for Linear Parabolic and Hyperbolic PDEs [PDF]
, 2021 The Discontinuous Petrov-Galerkin (DPG) method with optimal test functions intends to approximate Partial Differential Equations (PDEs). It was introduced by Demkowicz and Gopalakrishnan in 2010. The main idea of this method is to select optimal

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes
British Journal of Pharmacology, EarlyView.Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

DATA-DRIVEN SINGLE-/MULTI-DOMAIN SPECTRAL METHODS FOR STOCHASTIC FRACTIONAL PDES [PDF]
, 2018 Fractional derivatives are integro-differential convolution type operators with power law kernels, which seamlessly generalize the notion of standard integer order differentiation to their fractional counter parts.

British Journal of Pharmacology, EarlyView.Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Asymptotic behavior of splitting schemes involving time-subcycling techniques [PDF]
, 2015 International audienceThis paper deals with the numerical integration of well-posed multiscale systems of ODEs or evolutionary PDEs. As these systems appear naturally in engineering problems, time-subcycling techniques are widely used every day to ...

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances
Computer Graphics Forum, EarlyView.We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations
Computer Graphics Forum, EarlyView.Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies
Mathematical Finance, EarlyView.ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility
Molecular Microbiology, EarlyView.Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...
