Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.

A comparison of impedance boundary conditions for flow acoustics [PDF]

open access: yes, 2013
Acoustic liners remain a key technology for reducing community noise from aircraft engines. The choice of optimal impedance relies heavily on the modeling of sound absorption by liners under grazing flows.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3106-3122, November 2026.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Lonely and Sick: The Role of Social Media in Consumer Practices of Relief

open access: yesPsychology &Marketing, Volume 43, Issue 11, Page 3129-3146, November 2026.
ABSTRACT Loneliness is increasingly recognized as a major mental health concern, yet the role of social media in alleviating it remains poorly understood. This study asks how social media help consumers cope with loneliness amid chronic illness. Focusing on women living with endometriosis, an under‐recognized and often stigmatized condition marked by ...
