On partially null and pseudo null curves in the semi-euclidean space $$ R^{4}_{2} $$

open access: yesJournal of Geometry, 2006
In this paper, we obtain the Frenet equations of a pseudo null and a partially null curves, lying fully in the semi–Euclidean space $$ R^{4}_{2} $$ , and classify all such curves with constant curvatures.

Modelling bedload transport at the network scale in a glacier‐fed Alpine river system

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
We adapted the network‐scale sediment transport and connectivity model D‐CASCADE for Alpine environments and applied it to the Sulden/Solda catchment (Italy). For the first time, we validate the model with continuous bedload measurements at the catchment outlet and evaluate the plausibility of bedload dynamics along the river network with field ...

Gatekeepers or Nightmares? Exploring Academics' Experiences With the Reviewer 2 Phenomenon

open access: yesLearned Publishing, Volume 39, Issue 3, July 2026.
ABSTRACT This study investigates the experiences of 93 academics with Reviewer 2 through a phenomenological research design. Data were collected through an opinion form and analysed using descriptive and content analysis to uncover themes, subthemes and codes. The findings revealed that Reviewer 2 is often perceived as a source of unconstructive, harsh

Impact of Socioeconomic Disparities Among Pediatric Airway and Otology Patients on Access to Care

open access: yesLaryngoscope Investigative Otolaryngology, Volume 11, Issue 3, June 2026.
Otology patients were more likely to be referred to the specialty clinic, have fewer no shows, and attend a higher number of follow up visits despite having minimal differences in social demographics. Future study targeting follow‐up and retention for airway clinic patients is needed.
