Introduction: In unsupervised learning, data clustering is essential. However, many current algorithms have issues like early convergence, inadequate local search capabilities, and trouble processing ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...

Abstract: This work proposes a hybrid nonlinear control algorithm for electric power steering (EPS) systems, designed by integrating backstepping control (BSC), sliding mode control (SMC), and ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

We report a method for the recovery of hearts for transplantation from deceased donors after circulatory death that obviates the need for thoracoabdominal normothermic regional perfusion or ex situ ...

The cyclical, now AI-fueled, “SEO is dead” panic cycle is in full swing. But here’s what most of those headlines miss: Search isn’t a platform, it’s a behavior. Whether people are typing into Google ...
