Periodic Halpha variations in GL 581: Further evidence for an activity origin to GL 581d
, 2015 Radial velocity measurements showed evidence that the M dwarf GL 581 might host a planet, GL 581d, in the so-called "habitable zone" of the star. A study of Halpha in GL 581 demonstrated that changes in this activity indicator correlated with radial ...

Shape Memory Polymer‐Based Hook‐and‐Loop Fastener for Robust Bonding and on‐Demand Easy Separation
Advanced Engineering Materials, EarlyView.A 3D shape memory polymer‐based hook‐and‐loop fastener, fabricated using projection microstereolithography and molding, offers tunable bonding strength through temperature control. When heated from 25 to 70 °C, the fastener softens and deforms easily, reducing bonding strength by 20‐fold for on‐demand easy separation.

Extreme Long Period Eclipsing Binary Epsilon Aurigae [PDF]
Journal of Astronomy and Space Sciences, 1990 From the study of a spectroscopic plate of epsilon Aurigae, we can measure the radial velocity and the relative abundance for this eclipsing binary. Calculated radial velocity is -37 Km/s and the abundance of [Fe] is estimated as -1.5.

Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Advanced Engineering Materials, EarlyView.Previous studies on additive manufacturing primarily focus on the mechanical properties of as‐printed components. In the present work, researchers explore the potential of employing novel thermomechanical postprocessing techniques to improve the microstructure after printing.

Galactic kinematics and dynamics from radial velocity experiment stars
, 2014 We analyse the kinematics of 400000 stars that lie within 2kpc of the Sun and have spectra measured in the RAdial Velocity Experiment (RAVE). We decompose the sample into hot and cold dwarfs, red-clump and non-clump giants.
