Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Pathways to care in pinyon–juniper woodlands: Insights from Indigenous‐led monitoring and a public survey

People and Nature, EarlyView.
Abstract Conservation decisions often require navigating tensions among ecological, cultural, economic and social priorities. While debates frequently centre on single‐species outcomes, less is known about how care for landscapes may contribute to co‐stewardship.

Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

Pest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

Multi‐scale flow analysis for scale‐aware urban canopy models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We found that scale‐aware models are necessary when numerical weather prediction models approach hectometric resolution, which is associated with a characteristic length‐scale of morphological heterogeneity. This morphology‐dependent length‐scale indicates that resolved and unresolved heterogeneity are equally important.

Balancing accuracy and speed: A multi‐fidelity ensemble Kalman filter with a machine learning surrogate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate the use of a multi‐fidelity ensemble Kalman filter (EnKF) in which the low‐fidelity model is a machine‐learning model, instead of a traditional low‐resolution model. Results with the Lorenz‐2005 and quasi‐geostrophic models show that we can achieve improved accuracy within the same computational budget compared with the standard EnKF ...
