Planet Formation in Circumbinary Configurations: Turbulence Inhibits Planetesimal Accretion [PDF]

, 2012
The existence of planets born in environments highly perturbed by a stellar companion represents a major challenge to the paradigm of planet formation.

Sustainable One‐Pot Electrochemical Approach for Entrapment of Multi‐Enzymes and Biocompatible Redox Mediator

ChemPlusChem, EarlyView.
Novel enzyme‐modified carbon felt electrodes are constructed for efficient bio‐electrocatalysis. Simultaneous electrodeposition of pyrrole and neutral red provides a facile one‐step approach for enzyme immobilization. The biocompatible conductive polymer matrix performs for the entrapment of dehydrogenase enzymes on the electrode and ensures sufficient

Planet Packing in Circumbinary Systems

, 2013
The recent discovery of planets orbiting main sequence binaries will provide crucial constraints for theories of binary and planet formation. The formation pathway for these planets is complicated by uncertainties in the formation mechanism of the host ...

Adaptive Optics Images of Kepler Objects of Interest [PDF]

, 2012
All transiting planets are at risk of contamination by blends with nearby, unresolved stars. Blends dilute the transit signal, causing the planet to appear smaller than it really is, or produce a false positive detection when the target star is blended ...

Meniscal forces and knee kinematics are affected by tibial slope modifying high tibial osteotomy

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To quantify the effect of increasing the posterior tibial slope (PTS) on knee kinematics and the resultant medial and lateral meniscal forces. Methods In this controlled laboratory study, a 6 degrees of freedom (DOF) robotic testing system was used to apply external loading conditions to seven fresh‐frozen human cadaveric knees: (1 ...

Signs of Similar Stellar Obliquity Distributions for Hot and Warm Jupiters Orbiting Cool Stars

The Astronomical Journal
Transiting giant planets provide a natural opportunity to examine stellar obliquities, which offer clues about the origin and dynamical histories of close-in planets.

How to build Tatooine: reducing secular excitation in Kepler circumbinary planet formation

, 2012
Circumbinary planetary systems recently discovered by Kepler represent an important testbed for planet formation theories. Planetesimal growth in disks around binaries has been expected to be inhibited interior to ~10 AU by secular excitation of high ...

Age is not a primary risk factor for ACL injury—A comprehensive review of ACL injury and reinjury risk factors confounded by young patient age

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Revision surgery after anterior cruciate ligament reconstruction (ACL‐R) is hypothesized to be the result of an interplay between factors associated with the anatomy, physiological characteristics and environment of the patient. The multifactorial nature of revision ACL‐R risk is difficult to quantify, and evidence regarding the independent ...

Kepler-16b: safe in a resonance cell

, 2013
The planet Kepler-16b is known to follow a circumbinary orbit around a system of two main-sequence stars. We construct stability diagrams in the "pericentric distance - eccentricity" plane, which show that Kepler-16b is in a hazardous vicinity to the ...

Solvent‐Free, Degradable Resins for 3D Inkjet Printing Based on Silyl Ether and Amino Acid Phosphoramide Photomonomers

Macromolecular Materials and Engineering, EarlyView.
Inkjet 3D printing enables multi‐material, scalable, noncontact production of biomaterials like tissue scaffolds but is limited the non‐availability of low toxicity, low viscosity and biodegradable photopolymers. This research introduces biocompatible inks based on amino acid phosphoramides and phosphorodiamidates with tunable degradation, expanding ...
