Kepler Presearch Data Conditioning I - Architecture and Algorithms for Error Correction in Kepler Light Curves

, 2012
Kepler provides light curves of 156,000 stars with unprecedented precision. However, the raw data as they come from the spacecraft contain significant systematic and stochastic errors.

Posterolateral tibial plateau fractures are associated with anterolateral complex injuries of the knee in primary ACL injury

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Posterolateral tibial plateau fractures (PLTFs) have been increasingly studied due to their association with soft tissue injuries around the knee. This prospective study aimed to determine whether the presence of PLTFs is associated with soft tissue injuries around the knee and correlates with an increased preoperative quantitative ...

Kepler Bonus: Light Curves of Kepler Background Sources

The Astronomical Journal, 2023
NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...

Viscosity Reduction in Diluted Polyethylene Melts: A Comparative Study of Semiempirical, Viscoelastic, and Equation‐of‐State Modeling Frameworks

Polymer Engineering &Science, EarlyView.
Schematic of the in‐line rheometry setup and the evaluation of three distinct modeling frameworks (semiempirical, viscoelastic, and EOS) to predict viscosity reduction in diluted polyethylene melts via time‐concentration superposition (Illustration generated via ChatGPT).

Diffusion Coefficients of Organic Compounds in Molten High‐Impact Polystyrene

Polymer Engineering &Science, EarlyView.
Schematic overview of the determination of diffusion coefficients in molten high‐impact polystyrene. ABSTRACT Polystyrene (PS) is a widely used packaging material, but its recycling for food‐contact applications is still limited, partly due to a lack of quantitative data on the migration behavior of potential contaminants.

Linear frictional forces cause orbits to neither circularize nor precess

, 2008
For the undamped Kepler potential the lack of precession has historically been understood in terms of the Runge-Lenz symmetry. For the damped Kepler problem this result may be understood in terms of the generalization of Poisson structure to damped ...

A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations

The Astronomical Journal
Kepler-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 ...
