From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Experimental Study of Heat Transfer Enhancement in a Heated Tube Caused by Wire-Coil and Rings

open access: yesJournal of Applied Fluid Mechanics, 2015
This study investigates heat transfer characteristics and the pressure drop of a horizontal double pipe heat exchanger with wire coil inserts. The amplification of convection heat transfer coefficient in the heat exchanger reduces the weight, size and ...

Global behaviour corresponding to the absolute instability of the rotating-disc boundary layer [PDF]

open access: yes, 2003
A study is carried out of the linear global behaviour corresponding to the absolute instability of the rotating-disc boundary layer. It is based on direct numerical simulations of the complete linearized Navier–Stokes equations obtained with the novel ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Integrating multimodal data and machine learning for entrepreneurship research

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

Salivary biomarkers in sleep‐related disorders

open access: yesSleep Research, EarlyView.
Abstract The exploration of salivary biomarkers has emerged as a promising avenue in the diagnosis and management of sleep‐related disorders, such as obstructive sleep apnea (OSA), insomnia, and sleep deprivation. Saliva is a noninvasive biofluid that contains a wealth of biological markers, reflecting both local and systemic physiological changes ...

White light emitting molecular logic gates

open access: yesSmart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.
