D-BRANES, CYCLIC SYMMETRY AND NONCOMMUTATIVE GEOMETRY [PDF]
In this paper, we study the open string modes, describing the world-volume of a D p-brane, for its cyclic symmetry in the presence of a magnetic field. We outline the analogy between cyclic and noncommutative symmetries and demonstrate the point-splitting prescription to explain some of the unusual ir phenomena observed in a noncommutative field ...

This study demonstrates how optimizing laser power, scanning speed, and hatching distance in laser powder bed fusion can boost the productivity of Inconel 718 manufacturing by up to 29% while maintaining mechanical integrity. The work delivers a validated process window and cost–time analysis, offering industry‐ready guidelines for efficient additive ...

On Almost C(α)-Manifold Satisfying Certain Curvature Conditions
This research article is about the geometry of the almost C(α)- manifold. Some important properties of the almost C(α)- manifold with respect to the W_3- curvature tensor, such as W_3-flat and W_3- semi-symmetry, are investigated.

Movable vs Monodromy Nilpotent Cones of Calabi-Yau Manifolds
We study mirror symmetry of complete intersection Calabi-Yau manifolds which have birational automorphisms of infinite order. We observe that movable cones in birational geometry are transformed, under mirror symmetry, to the monodromy nilpotent cones ...

Noncommutative geometry and twisted conformal symmetry [PDF]
The twist-deformed conformal algebra is constructed as a Hopf algebra with twisted co-product. This allows for the definition of conformal symmetry in a non-commutative background geometry. The twisted co-product is reviewed for the Poincar algebra and the construction is then extended to the full conformal algebra.

Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Symmetry of Square Contingency Tables Using Simplicial Geometry
Two-way contingency tables illustrate the relationship between two discrete variables. Their corresponding probability tables can be regarded as an element in a simplex.

Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Controlling transport of underdamped particles in two-dimensional driven Bravais lattices
We demonstrate the directed transport of underdamped particles in two-dimensional lattices of arbitrary geometry driven by an unbiased AC driving force.
