Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications
Advanced Intelligent Systems, EarlyView.Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

Migration of Protoplanets in Radiative Disks [PDF]
, 2008 In isothermal disks the migration of protoplanets is directed inward. For small planetary masses the standard type-I migration rates are so fast that this may result in an unrealistic loss of planets into the stars. We investigate the planet-disk interaction in non-isothermal disks and analyze the magnitude and direction of migration for an extended ...

UniverseAccretion and migration usually proceed concurrently for giant planet formation in the natal protoplanetary disks. Recent works indicate that the concurrent accretion onto a giant planet imposes significant impact on the planetary migration dynamics in ...

Narrative, Scale, and Two Refugee Crises in Comparison in Italian Media
Diegesis: Interdisziplinäres E-Journal für Erzählforschung, 2023 Bringing together narrative theory, migration studies, and contemporary discussions in the environmental humanities, this article considers the significance of the concept of scale for media narratives on migration.

Large Fluctuations within 1 au in Protoplanetary Disks
The Astrophysical JournalProtoplanetary disks are often assumed to change slowly and smoothly during planet formation. Here, we investigate the time evolution of isolated disks subject to viscosity and a disk wind. The viscosity is assumed to increase rapidly at around 900 K due

Predicting the Dominant Formation Mechanism of Multiplanetary Systems
The Astrophysical Journal LettersMost, if not all, Sun-like stars host one or more planets, making multiplanetary systems commonplace in our Galaxy. We utilize hundreds of multiplanet simulations to explore the origin of such systems, focusing on their orbital architecture.
