Research on the Dynamic Response of a Cracked-Spur Gear System with Parameter Uncertainty
MachinesIn this paper, the time-varying mesh stiffness (TVMS) of a gear is meticulously derived using the potential energy method (PEM) and an analytical expression for it is obtained.

Epiphora: A Structured Diagnostic Approach for the Otolaryngologist
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Introduction Epiphora, or excessive tearing, has historically been predominantly managed by ophthalmologists. However, as there is substantial overlap between ophthalmic and otolaryngologic anatomy and pathology that may contribute to epiphora, patients with this symptom often present to otolaryngologists as well.

Investigation into the tribodynamics of spur gear pairs considering pitch deviations and lubrication
FrictionPitch deviation, a type of longwave deviation, has been demonstrated to be a significant contributor to noise generation in the drive trains of motor vehicles operating at relatively high speeds. To date, numerous studies have investigated the effects of

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT With the retirement of 21GW of legacy coal fleet looming, the task to replace Australia's thermal capacity with alternative firmed renewable ‘bulk energy’ solutions is non‐trivial. Indeed, calibrating necessary capital investment in new plant stock with efficient economic outcomes, vis‐à‐vis cost and reliability, represents a fundamental ...

Improving Population Health Through Housing Policy: Lessons From the Public Housing Program
The Milbank Quarterly, EarlyView.Policy Points Housing is a fundamental social determinant of health and is particularly amenable to policy intervention. Policies that seek to improve health should improve housing quality, affordability, and stability. The public housing program has improved health across the life course, but the structure of the program currently limits its ...
