The Kepler Light Curves of AGN: A Detailed Analysis [PDF]
, 2018 We present a comprehensive analysis of 21 light curves of Type 1 active galactic nuclei (AGN) from the Kepler spacecraft. First, we describe the necessity and development of a customized pipeline for treating Kepler data of stochastically variable ...

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Functional alignment (FA) aims to achieve a symmetric, rectangular extension gap and a rectangular or trapezoidal flexion gap, positioning the components in a manner that reduces the compromises to the soft tissue envelope. Because the FA surgeon can accomplish this goal with a multitude of adjustments to the components' position or ...

The Accelerated Kepler Problem
, 2007 The accelerated Kepler problem is obtained by adding a constant acceleration to the classical two-body Kepler problem. This setting models the dynamics of a jet-sustaining accretion disk and its content of forming planets as the disk loses linear ...

A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
The Astronomical JournalKepler-51 is a ≲1 Gyr old Sun-like star hosting three transiting planets with radii ≈6–9 R _⊕ and orbital periods ≈45–130 days. Transit timing variations (TTVs) measured with past Kepler and Hubble Space Telescope (HST) observations have been ...

Artificial intelligence agents in orthopaedics: Concepts, capabilities and the road ahead
Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Artificial intelligence (AI) is increasingly used in orthopaedics, yet current models are often limited to narrow, isolated tasks like analysing an X‐ray or predicting a single outcome. This paper introduces AI agents—a new class of AI systems designed to overcome these limitations. Unlike traditional AI, agents can autonomously manage complex,
