Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 470-483, December 2022., 2022 In Yellowstone Lake, Wyoming, lake trout carcasses are used to suppress invasive lake trout embryos in an effort to conserve native Yellowstone cutthroat trout. Using a field experiment, we determined that carcass treatment had limited, non‐target effects on benthic invertebrates.

Properties of the short period CoRoT-planet population I: Theoretical planetary mass spectra for a population of stars of 0.8 to 2 solar masses and orbital periods of less then 20 days [PDF]
arXiv, 2006 We study the planet populations in the discovery window of the CoRoT-space-telescope scheduled for launch on December 27th. We base the prediction on `first principles' calculations of planet formation in the framework of the planetesimal hypothesis. Aims: To provide a-priori planetary initial mass functions for confrontation with the CoRoT-planet ...

Star-planet magnetic interaction and evaporation of planetary atmospheres
, 2013 Stars interact with their close-in planets through radiation, gravitation, and magnetic fields. We investigate the energy input to a planetary atmosphere by reconnection between stellar and planetary magnetic fields and compare it to the energy input of ...

Miras, mass loss, and the origin of planetary nebulae [PDF]
International Astronomical Union Colloquium, 1981 Mira variables are found at the tip of the asymptotic giant branch, with L≈3000-5000Lʘ and TeH3000K. (Feast 1981; Willson 1981a). They are fundamental mode pulsators (Willson 1979, 1981a). A typical Mira has P~350 days, R~200-300Rʘ, M~1-2Mʘ (Willson 1979; 1981a).

Bleeding‐Mimetic Damage‐Detecting and Self‐Healing Modular Skin for Inflatable Structures
Advanced Robotics Research, EarlyView.A damage‐detecting and self‐healing system inspired by the human bleeding mechanism is developed for inflatable structures, using a liquid conductive elastomeric material enclosed in a small pouch. This material, composed of uncured elastomer, its curing agent, conductive particles, and a dispersant, solidifies only after being exposed to air and ...

The Trigonometric Parallax of the Brown Dwarf Planetary System 2MASSW J1207334-393254
, 2007 We have measured a trigonometric parallax to the young brown dwarf 2MASSW J1207334-393254. The distance [54.0 (+3.2,-2.8) pc] and space motion confirm membership in the TW Hydrae Association. The primary is a ~25 M_jup brown dwarf.

Yield estimation of summer maize based on multi‐source remote‐sensing data
Agronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022 Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution
