Deriving Schwarzschild and Kerr from the Einstein Equivalence Principle
G. Alencar
This manuscript demonstrates that the Schwarzschild and Kerr metrics can be derived fundamentally from the Einstein Equivalence Principle (EEP) without explicit reliance on the Ein…
Microcell Hot Spot and Smart Antennas Evaluation in WCDMA Macrocell System
Carlos H. M. Lima, Francisco R. P. Cavalcanti, Vicente A. de Sousa +1
The purpose of this contribution is to analyze a hierarchical cell structure with a hot spot embedded in a WCDMA macrocellular system. Particular attention is paid to the impact of…
FU-Mamba: A Frequency-Enhanced Dynamic Scanning Framework for Oralscan Image Segmentation
Xinxin Zhao, Jinpeng Ye, Bo Wei +8
Oralscan image segmentation is essential for computer-aided diagnosis and treatment planning in digital dentistry. However, existing visual state space models (SSMs) often rely on…
Evaluating Language Models on Cross-Language Code Functional Equivalence
Hui Sun, Anderson Uchôa, Rohit Gheyi +1
Background: Large Language Models (LLMs) have demonstrated strong performance across a variety of code-understanding tasks, leading many to believe that they can reason about progr…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
The Dirac oscillator in the curved spacetime of a cloud of strings
R. R. S. Oliveira
In this paper, we determine the relativistic bound-state solutions for the Dirac oscillator (DO) in the curved spacetime of a cloud of strings in -dimensions, where such sol…
