Revision of the Elusive Harvestmen Genus Discocyrtulus Roewer, 1927 (Opiliones: Laniatores: Gonyleptidae): Investigating the Presumed Northeastern Brazilian Discocyrtus‐Like Relatives

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT A maximum parsimony analysis based on morphological characters (23 taxa; 98 characters; 1951 scorings) was conducted to test the monophyly of Discocyrtulus Roewer, 1927, and to assess its phylogenetic relationships within Gonyleptidae. The results recover the species currently assigned to Discocyrtulus as phylogenetically distant from ...

Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

Study of wing vortex generation and their mitigation through winglets

open access: yes, 2022
reservedIn questa tesi si è cercato di spiegare il comportamento dei vortici di estremità alare e di come essi possano essere mitigati attraverso l'uso di piccoli profili alari, detti winglet. Da prima si è cominciato con l'introdurre il comportamento
