The Ontological Nullity of Gravitational Singularities

This paper presents a comprehensive theoretical framework for analyzing post-merger gravitational wave signals, specifically addressing the existence of "echoes" as potential signatures of quantum horizon structures or Exotic Compact Objects (ECOs). Focusing on the landmark GW150914 event, we re-examine boundary conditions at the Schwarzschild radius ...

Single Smooth Waveform Command‐Shaping Control of Overhead Crane Systems Utilizing Two‐Stage Acceleration–Deceleration Profile for Short‐Moving Point‐to‐Point Maneuver

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern industrial demand for efficient material handling in confined spaces has driven the need for overhead cranes capable of short‐distance point‐to‐point maneuvers without compromising payload stability. Conventional three‐stage shaper profiles, experiencing acceleration, cruising, and deceleration, become inefficient or infeasible for ...

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...

Iterative Modeling via Structural Diffusion (IMSD): Exploring Fold‐Switching Pathways in Metamorphic Proteins Using AlphaFold2‐Based Generative Diffusion Model UFConf

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Metamorphic proteins (MPs) can fold into two or more distinct spatial structures. Increasing interest in MPs has spurred the search for computational tools to predict proteins fold‐switching potential and model their refolding pathways. Here we address this problem by using the recently reported generative diffusion predictor UFConf, based on ...

A regional implementation of a mixed finite‐element, semi‐implicit dynamical core

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A regional version of a new dynamical core with an iterated semi‐implicit time discretisation and mixed finite‐element spatial discretisation is described. This involves modifying the mixed‐system and Helmholtz‐preconditioner equations to use lateral boundary condition (LBC) data specified by a driving model.
