Narrative, Scale, and Two Refugee Crises in Comparison in Italian Media

open access: yesDiegesis: 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.

Evolutionary outcomes for pairs of planets undergoing orbital migration and circularization: second order resonances and observed period ratios in Kepler's planetary systems

open access: yes, 2015
In order to study the origin of the architectures of low mass planetary systems, we perform numerical surveys of the evolution of pairs of coplanar planets in the mass range $(1-4)\ \rmn{M}_{\oplus}.$ These evolve for up to $2\times10^7 \rmn{yr}$ under a

Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 7, July 2025.
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.

Plastomic studies inform the mechanisms of edaphic adaptation in North American species in the tribe Thelypodieae (Brassicaceae)

open access: yesAmerican Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Premise Adaptation to edaphic environments is vital for plant survival. The tribe Thelypodieae (Brassicaceae) thrives in diverse edaphic conditions, including harsh serpentine soils. A robust phylogeny is essential to understanding the edaphic evolution in this tribe but is challenging to obtain due to incomplete lineage sorting, hybridization,

Orbital Migration Through Atmospheric Mass Loss

open access: yesThe Astronomical Journal
Atmospheric mass loss is thought to have strongly shaped the sample of close-in exoplanets. These atmospheres should be lost isotropically, leading to no net migration on the planetary orbit.

Two-Dimensional Study of the Propagation of Planetary Wake and the Indication to Gap Opening in an Inviscid Protoplanetary Disk

open access: yes, 2010
We analyze the physical processes of gap formation in an inviscid protoplanetary disk with an embedded protoplanet using two-dimensional local shearing-sheet model. Spiral density wave launched by the planet shocks and the angular momentum carried by the

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Predicting the Dominant Formation Mechanism of Multiplanetary Systems

open access: yesThe Astrophysical Journal Letters
Most, 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.
