Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles
Journal of Field Robotics, EarlyView.ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Gravitational lensing by deformed Horava-Lifshitz black hole in rainbow gravity
Physics Letters BIn this study, we investigate the gravitational lensing effects of deformed Horava-Lifshitz black holes, considering both strong and weak-field limit approximations and incorporating the impact of rainbow functions.

Sustainable Development, EarlyView.ABSTRACT The role of Development Finance Institutions (DFIs) in achieving the Sustainable Development Goals (SDGs) is a topic of growing scholarly importance. While existing literature has mapped the thematic scope of this field, a critical diagnosis of its intellectual structure and inherent biases is missing.

Residual Test to Search for Microlensing Signatures in Strongly Lensed Gravitational Wave Signals
The Astrophysical JournalWhen a gravitational wave signal encounters a massive object, such as a galaxy or galaxy cluster, it undergoes strong gravitational lensing, producing multiple copies of the original signal.

Common purpose advantage: Reviving a managerial theory of the firm?
Strategic Management Journal, EarlyView.Abstract Research Summary What is the most effective way to distribute organizational objectives across managers? While prior work suggests managers should each focus on a single objective, we draw on Barnard's original insights on corporate purpose to identify conditions when managers pursuing the full set of objectives is advantageous.

A dearth of dark matter in strong gravitational lenses [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 I show that the lensing masses of the SLACS sample of strong gravitational lenses are consistent with the stellar masses determined from population synthesis models using the Salpeter IMF. This is true in the context of both General Relativity and modified Newtonian dynamics, and is in agreement with the expectation of MOND that there should be little ...

Systems Research and Behavioral Science, EarlyView.ABSTRACT The emergence of cooperation in natural selection has been successfully studied using game theory and, despite the underlying selfish nature of the evolutionary process, a spectrum of plausible mechanisms have been proposed to determine the conditions under which cooperative behaviour is likely to occur.

Generating Dark Matter Subhalo Populations Using Normalizing Flows
The Open Journal of AstrophysicsStrong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy.
