Hessian manifolds of positive constant Hessian sectional curvature
Hessian structure on a manifold is a geometric structure consisting of a pair $(\nabla,g)$ of an affine connection $\nabla$ and a Riemannian metric $g$ satisfying certain compatibility conditions. It is also known as a dually flat structure in information geometry.

Medial Axis Aware Learning of Signed Distance Functions
Abstract We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of the surface, is explicitly taken into account through a higher‐order variational formulation that enforces linear growth ...

Primal SPH Solver for Strongly Coupled Multiphase Simulations with High Density Ratios
Abstract In recent years, the Smoothed Particle Hydrodynamics (SPH) approach has been increasingly used for multiphase simulations involving interactions between diverse materials. A critical component of an SPH simulator is the pressure solver, which not only facilitates the simulation of compressible or incompressible fluids but also handles contact ...

Semi-supervised regression using Hessian energy with an application to semi-supervised dimensionality reduction [PDF]
Semi-supervised regression based on the graph Laplacian suffers from the fact that the solution is biased towards a constant and the lack of extrapolating power.

GNOCHI: Generative Neural mOdel for Close Human‐Human Interactions
Abstract Creating realistic 3D human‐human interactions in virtual environments is challenging due to the high degrees of freedom in human body and the need for physically accurate poses that do not collide with each other. Traditional methods for humanhuman interaction are based on motion tracking or 3D body reconstruction, but lack generative ...

Abstract We present a fast, robust method for continuous collision detection (CCD) directly between pairs of complex signed distance fields (SDFs). By casting CCD as an alternating spatio‐temporal optimization and driving a small set of smartly sampled surface points along SDF tangent spaces, our approach avoids dense sampling or triangle meshes ...

On Topology of Compact Hessian Manifolds
We investigate the global topological constraints and structural properties of compact Hessian manifolds. By establishing novel fibration and splitting theorems, we confirm Chern's conjecture on the vanishing of the Euler characteristic for this class of affine manifolds.

The value of the market: Heterogeneity and gains from trade in permit and quota markets
Abstract Many quantity constraining policies are in place in market economies. Conditions for trade in these rights or obligations to produce can be politically sensitive policy choices. Benefits from trade, and so the value of the associated market, are determined by heterogeneity among potential traders.

Shown is a typical detail of a high‐resolution crystal structure (PDB ID 1B5E, chain A) showing the nearness of a phenylalanine residue, Phe24, and a lysine residue, Lys32, that are not engaged in the proposed cation–π interaction. The study statistically examines charged residues near phenylalanine's aromatic ring, supported by quantum chemical ...

Monopoly Versus Dual‐Channel Distribution With Multiple Retailers
ABSTRACT This paper examines how downstream competition shapes a manufacturer's decision to adopt a dual‐channel structure—supplying independent retailers via secret two‐part tariff contracts while also operating a direct channel. We show that the shape of the inverse demand function plays a key role in this decision.
