Surfaces in E3 invariant under a one parameter group of isometries of E3
Anais da Academia Brasileira de Ciências, 2000 We develop a convenient surface theory in E³ in order to apply it to the class of the surfaces invariant under a one-parameter group of isometries of E³.

Traveling waves for the closed hypersurfaces in central force fields
Bulletin of Mathematical SciencesWe consider the front propagation problems for the hyperbolic mean curvature motion in central force fields. Problems of this type describe the long time behavior for the electrically charged membrane with a constant charge per area and a radially ...

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Ordinary differential equations in affine geometry
Le Matematiche, 1996 The method of qualitative analysis is used, as applied to a class of fourth order, nonlinear ordinary differential equations, in order to classify, both locally and globally, two classes of hypersurfaces of decomposable type in affine geometry: those ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones
Advanced Engineering Materials, EarlyView.A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V
Advanced Engineering Materials, EarlyView.This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

A Small Cosmological Constant from a Large Number of Extra Dimensions
UniverseIn this article, we consider the 4 + n dimensional spacetimes among which one is the four dimensional physical Universe and the other is an n-dimensional sphere with constant radius in the framework of Lanczos-Lovelock gravity. We find that the curvature
