Investigating generalized polytropic compact objects in f(R) gravity

European Physical Journal C: Particles and Fields
This paper investigates realistic anisotropic matter configurations for spherical symmetry in f(R) gravity. The solutions obtained from Starobinsky model are used to determine the behavior of PSR J0740+6620, PSR J0348+0432 and 4U 1608-52 with polytropic ...

LiDAR-Radar Dual-Stream Pointcloud Aggregation Mid-Fusion With Multi-Coordinate System for 3D Semantic Segmentation

IEEE Access
This paper proposes Dual-stream Point aggregation Mid-fusion with Multi-coordinate system (DPMM), which leverages LiDAR-radar fusion with velocity information and 3D coordinate compatibility for improved semantic segmentation in autonomous driving. While

Numerical study on inter-particle effects for multiple reacting biomass and coal particles based on Micro-CT morphology

Heliyon
Co-firing of biomass with coal combines the environmental benefits of renewable biomass with the high energy content of coal. Although the common numerical simulation treats the biomass and coal particles with ideal morphology, real particles often ...

Calogero-Sutherland-type quantum systems, generalized hypergeometric functions and superintegrability for integral chains

Journal of High Energy Physics
We reinvestigate the Calogero-Sutherland-type (CS-type) models and generalized hypergeometric functions. We construct the generalized CS operators for circular, Hermite, Laguerre, Jacobi and Bessel cases and establish the generalized Lassalle-Nekrasov ...

Towers with Golden Orbs. Motif of Cupolaed Spires with Spherical Supports

Biuletyn Historii Sztuki
The article is devoted to the hitherto overlooked architectural motif of spherical supports in tower spires, observed in northern Europe since the early 17th century. Probably derived from the obelisk ball-based motif popular in iconography.

Two-Variable Wilson Polynomials and the Generic Superintegrable System on the 3-Sphere

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We show that the symmetry operators for the quantum superintegrable system on the 3-sphere with generic 4-parameter potential form a closed quadratic algebra with 6 linearly independent generators that closes at order 6 (as differential operators ...

Intracranial Aneurysm Detection using Spherical Representations

, 2023
The detection of intracranial aneurysms from 3D time-of-flight magnetic resonance angiography (TOF-MRA) images is a problem of increasing clinical importance. Recently, a streak of methods have shown promising performance by adapting neural networks for 3D semantic segmentation with a patch-based approach.
