Eulerian and Lagrangian Comparison of Wind Jets in the Tokar Gap Region
Fluids, 2020 The Lagrangian and Eulerian structure and dynamics of a strong wind event in the Tokar Gap region are described using a Weather Research and Forecasting (WRF) model hindcast for 2008. Winds in the Tokar Gap reach 25 m s−1 and remain coherent as a jet far

Room for Improvement: Why Finitist Arguments Do Not Check Out
Analytic Philosophy, EarlyView.ABSTRACT We examine several new and underexplored arguments for the finitude of the past and the impossibility of Hilbert's Hotel. The first argument concludes that Hilbert's Hotel is impossible due to an alleged contradiction arising from the causal powers of infinitely many guests.

Astronomy & AstrophysicsPredicting the nonlinear evolution of cosmic structure from initial conditions is typically approached using Lagrangian, particle-based methods. These techniques excel in terms of tracking individual trajectories, but they might not be suitable for ...

Numerical Analysis of Erosion Caused by Biomimetic Axial Fan Blade
Advances in Materials Science and Engineering, 2013 Damage caused by erosion has been reported in several industries for a wide range of situations. In the present work, a new method is presented to improve the erosion resistance of machine components by biomimetic method.

DNA Sequence Assembly and Multiple Sequence Alignment by an Eulerian Path Approach
Cold Spring Harbor Symposia on Quantitative Biology, 2003 We describe an Eulerian path approach to the DNA fragment assembly that was originated by Idury and Waterman 1995, and then advanced by Pevzner et al. 2001b. This combinatorial approach bypasses the traditional “overlap-layout-consensus” approach and successfully resolved some of the troublesome repeats in practical assembly projects.

Improving Christofides' Algorithm for the s-t Path TSP [PDF]
, 2011 We present a deterministic (1+sqrt(5))/2-approximation algorithm for the s-t path TSP for an arbitrary metric. Given a symmetric metric cost on n vertices including two prespecified endpoints, the problem is to find a shortest Hamiltonian path between ...

Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 926-946, 10 April 2026.ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...

MathematicsAtherosclerosis, marked by elevated plaque formation, occurs due to stenosis, which narrows the arterial walls and alters the natural flow path. Previous research has shown that the likelihood of high-rupture stenosis can be linked to temperature ...

Hierarchical Testing of a Hybrid Machine Learning‐Physics Global Atmosphere Model
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Machine learning (ML)‐based models have demonstrated high skill and computational efficiency, often outperforming conventional physics‐based models in weather and subseasonal predictions. While prior studies have assessed their fidelity in capturing synoptic‐scale atmospheric dynamics, their performance across timescales and under out‐of ...
