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 ...

A Reidentification of Six Candidate Gravitationally Lensed Gamma-Ray Bursts
The Astrophysical JournalThe gravitational lensing effect of gamma-ray bursts (GRBs) holds significant and diverse applications in the field of astronomy. Nevertheless, the identification of millilensing events in GRBs presents substantial challenges.

Science Education, EarlyView.ABSTRACT This multiple case study explores the intersections of queerness/transness and science education through a combined framework of queer theory, intersectionality, the construct of figured worlds and science identity. The study uses a life‐history approach to characterize the trajectories of three purposefully selected queer individuals who are ...

Cluster Lensing Mass Inversion (CLUMI+): Combining Dynamics and Weak Lensing around Galaxy Clusters
The Astrophysical JournalWe present clumi+ , a self-consistent, multiprobe methodology for reconstructing the mass distribution in and around galaxy clusters by combining gravitational lensing and dynamical observations. Building on the joint likelihood framework of K.

Lectures on Gravitational Lensing [PDF]
, 1996 These lectures give an introduction to Gravitational Lensing. We discuss lensing by point masses, lensing by galaxies, and lensing by clusters and larger-scale structures in the Universe. The relevant theory is developed and applications to astrophysical

Gravitational lensing effects on sub-millimetre galaxy counts
, 2013 We study the effects on the number counts of sub-millimetre galaxies due to gravitational lensing. We explore the effects on the magnification cross section due to halo density profiles, ellipticity and cosmological parameter (the power-spectrum ...

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.

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.
