Generalized second-order partial derivatives of 1/r
The generalized second-order partial derivatives of 1/r, where r is the radial distance in 3D, are obtained using a result of the potential theory of classical analysis.

Regular and semi-regular polytopes. II
[For part I see the review above.] The first section summarizes Part I, giving particular attention to the 3-dimensional point groups. The second section establishes subgroup relationships among the various irreducible reflection groups in 4 dimensions: 5 finite and 5 infinite.

Neuroinflammation in GAD65 Antibody‐Associated Epilepsy Measured Using [18F]DPA‐714 PET/MRI
ABSTRACT The timing for initiating immunotherapy in patients with glutamic acid decarboxylase 65 (GAD65) antibody‐associated epilepsy is a challenge. We used the translocator protein radioligand [18F]DPA‐714 and PET to evaluate brain microglial activation.

Global in time well-posedness of a three-dimensional periodic regularized Boussinesq system
Global in time weak solution to a regularized periodic three-dimensional Boussinesq system is proved to exist in energy spaces. This solution depends continuously on the initial data. In particular, it is unique.

A Regularized Interface Model for Simulating the Response of Adhesive Joints
A regularized interface damage model is presented grounded on the cohesive-zone concept. This is obtained using a gradient-based formulation, which is equivalent to the introduction of the laplacian of a scalar damage field into the threshold function of

Convex regularization of discrete-valued inverse problems
This work is concerned with linear inverse problems where a distributed parameter is known a priori to only take on values from a given discrete set.

Regular and completely regular differential operators [PDF]
We define the concept of completely regular ordinary differential operators and give various criteria for operators to belong to this class. We give also criteria for Birkhof regularity of ordinary differential operators in terms of the growth of the Green function and basis property.

This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Indoor Building Reconstruction from Occluded Point Clouds Using Graph-Cut and Ray-Tracing
Despite the increasing demand of updated and detailed indoor models, indoor reconstruction from point clouds is still in an early stage in comparison with the reconstruction of outdoor scenes.
