Dream is an offshore flame: Notes on archaeology and belonging

open access: yesAnthropology and Humanism, Volume 51, Issue 1, June 2026.
Abstract Set within an archaeology lab in Dunedin, Aotearoa, this creative non‐fiction piece traces the search for dwelling through the meticulous, repetitive labor of everyday practice. The narrative finds belonging not as a static identity, but as a continuous, tactile engagement with the material world.

Effect of Gear Backlash Function on the Dynamics Characteristic of Helical Gear

open access: yesJixie chuandong, 2015
A three- degree- of- freedom shaft- torsion coupling nonlinear dynamics model of a single-stage helical cylindrical gear transmission system is established,which included the nonlinear factors such as gear backlash,time- varying stiffness,transmission ...

Analysis on the Machining Twisting mechanism of Tooth Surface with Axial Modification of Helical Gear and Its Influence on Meshing Performance

open access: yesJixie chuandong, 2020
The formation mechanism of tooth surface twist in helical gear generating machining (worm grinding and hobbing) and the measure to reduce the tooth surface twist are mainly studied.

Evaluation of Catch Performance and Environmental Impact of Technical Gear Modifications for a More Sustainable Scallop Dredging Fishery

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions

Navigating the Genetic Risk of Chemotherapy‐Induced Hearing Loss in the Stria Vascularis

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 846-858, April 2026.
Cisplatin is a chemotherapy drug that causes permanent hearing loss by damaging a critical tissue lining the inner ear, called the stria vascularis (SV). Currently, the molecular mechanisms of SV damage are largely unknown and the incidence of ototoxicity in patients cannot be reliably predicted.

Gearbox fault diagnosis under different operating conditions based on time synchronous average and ensemble empirical mode decomposition [PDF]

open access: yes, 2009
In this paper, a new method is proposed by combining ensemble empirical mode decomposition (EEMD) with order tracking techniques to analyse the vibration signals from a two stage helical gearbox.

Harvesting the Spin–Orbit Interaction of Light to Generate Helicity‐Dependent Complex Rotational Motion in Optically Trapped Mesoscopic Matter

open access: yesNanophotonics, Volume 15, Issue 5, 16 March 2026.
Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.
