Null geodesics and shadows of slowly rotating wormholes immersed in dark matter halos

open access: yesEuropean Physical Journal C: Particles and Fields
We study slowly rotating traversable wormholes embedded in realistic galactic dark matter halos, including Navarro–Frenk–White (NFW), Bose–Einstein Condensate (Thomas-Fermi, TF), and pseudo-isothermal (PI) profiles.

Inhomogeneity of Isoparametric Hypersurfaces of OT-FKM Type in the Pseudo-sphere

open access: yesTokyo Journal of Mathematics
We study isoparametric hypersurfaces, whose principal curvatures are all constant, in the pseudo-Riemannian space forms. In this paper, we investigate two topics. Firstly, according to representations of Clifford algebras, we give a construction of Clifford systems of signature $(m, r)$ for any $(m, r)$ explicitly.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

open access: yesAdvanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Gas cells for tunable diode laser absorption spectroscopy employing optical diffusers. Part 2: Integrating spheres [PDF]

open access: yes, 2010
We have studied the effects of random laser speckle and self-mixing interference on TDLS based gas measurements made using integrating spheres. Details of the theory and TDLS apparatus are given in Part 1 of this paper and applied here to integrating ...

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Extensions of the mandala of Legendrian dualities for pseudo-spheres\ud in Lorentz-Minkowski space [PDF]

open access: yes, 2009
In this paper we show one-parameter families of Legendrian dualities between pseudo-spheres in\ud Lorentz-Minkowski space which are the extensions of four dualities in the previous research. Moreover, we construct new extrinsic differential geometries on

Women’s emancipation and Middlebrow culture in the Ljubica P. Radoičić’s novelistic oeuvre [PDF]

open access: yesGlasnik Etnografskog Instituta SANU
This paper’s starting point is to examine the evolution of the novelistic oeuvre of Ljubica P. Radoičić (1914–1991), which consists of the novels The Blood Wakes Up (1932), Dana Račić (1938) and One-Storey Houses (1954).
