Research Direction and Science Evaluation: The Role of Coherence and Alignment
Journal of Economics &Management Strategy, EarlyView.ABSTRACT The decisions of funding agencies greatly influence the direction of scientific research; however, our understanding of how applicants' research directions affect the selection process remains limited. In this study, we investigate how a project's coherence with a scientist's previous work and its alignment with current scientific trends ...

Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Collective Attention in Virtual Teams: A Pathway for Mitigating Communication Delays
Personnel Psychology, EarlyView.ABSTRACT Virtual work has become a defining feature of modern organizations, intensifying the need for strategies that support virtual team performance. Communication delays—prolonged intervals between sending and receiving messages—are one of the most persistent and consequential barriers to virtual team performance.

Attitude stabilization of a rigid spacecraft using gas jet actuators operating in a failure mode [PDF]
The attitude stabilization of a rigid spacecraft using control torques supplied by gas jet actuators about only two of its principal axes is considered. First, the case where the uncontrolled principal axis of the spacecraft is not an axis of symmetry is

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
