Structural Concrete, EarlyView.Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...

Pointwise multipliers for Sobolev and Besov spaces of dominating mixed smoothness
Journal of Mathematical Analysis and Applications, 2017 Under certain restrictions we describe the set of all pointwise multipliers in case of Sobolev and Besov spaces of dominating mixed smoothness. In addition we shall give necessary and sufficient conditions for the case that these spaces form algebras with respect to pointwise multiplication.

On pointwise a.e. convergence of multilinear operators [PDF]
, 2022 In this work we obtain the pointwise almost everywhere convergence for two families of multilinear operators: (a) truncated homogeneous singular integral operators associated with $L^q$ functions on the sphere and (b) lacunary multiplier operators of ...

A Spatio‐Temporal Dynamics Model for Indoor Environmental Forecasting
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.Accurate forecasting of indoor environmental conditions is essential for intelligent building operations and comfort‐oriented controls. However, reliable prediction remains challenging due to spatial heterogeneity across sensing locations, complex multi‐modal interactions, and nonstationary temporal dynamics.

Journal of Synchrotron Radiation, EarlyView.A small‐radius‐of‐curvature bendable mirror system is developed for dynamic focusing in X‐ray free‐electron laser and synchrotron radiation beamlines, and a transfer‐learning neural‐network and differential‐evolution framework is used for force‐to‐shape modeling and inverse optimization.

Pointwise multipliers on $L^1$ and related spaces
, 2006 We consider completely continuous and weakly compact multiplication operators on certain classical function spaces, more precisely on Lebesgue spaces $L^1$ on spaces $C(K)$ of continuous functions on a compact Hausdorff space K,and on the Hardy space $H^1$. We will describe such operators in terms of their defining symbols. Our characterizations extend

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.

A Real‐Time Multi‐Scale Neural Representation for Complex Surface Reflectance
Computer Graphics Forum, EarlyView.Abstract Recent machine learning methods have significantly advanced the state of the art in the classic problem of representing surface appearance over angle, space, and scale. The models tend, however, to be relatively heavy compared to traditional fixed‐function representations, making real‐time application challenging.

Essential Norms of Pointwise Multipliers in the Non‐Algebraic Setting
Mathematische NachrichtenABSTRACT Motivated by some recent results, but also referring to recognized classics, we compute the essential norm and the weak essential norm of multiplication operators acting between two distinct Köthe spaces both defined over the same ‐finite measure space.
