Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

The heart responds to pressure via the lung: Dive depth alters cardiac control in bottlenose dolphins

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dive depth independently modulated cardiac regulation in bottlenose dolphins during controlled voluntary dives. Dolphins performed dives to 0.5, 5 and 10 m with standardized dive durations, allowing the effects of depth on cardiovascular responses to be evaluated.

Long-Term Trends in Summertime Habitat Suitability for Delta Smelt, Hypomesus transpacificus

open access: yesSan Francisco Estuary and Watershed Science, 2008
The biological productivity of river-dominated estuaries is affected strongly by variation in freshwater inflow, which affects nursery habitat quality. Previous research has shown this is generally true in the upper San Francisco Estuary, California, USA;

High‐Dimensional Cumulative Sum Control Charts for Industrial Measurement Systems

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 7, Page 4342-4361, November 2026.
ABSTRACT High dimensional sensing in modern factories and energy assets produces thousands of correlated signals. Detecting small process shifts is challenging because many classical multivariate charts lose power or become unstable. We present two cumulative sum procedures for two sample monitoring that remain effective when the number of variables is

Sustainable Management of Global Platinum Group Resources in the Energy Transition: A Group Metabolism Perspective

open access: yesEarth's Future, Volume 14, Issue 10, October 2026.
Abstract As the transition toward carbon neutrality accelerates, platinum group metals (PGMs) have emerged as indispensable resources for the low‐carbon transformation. However, the supply of this PGM supply chain is very concentrated, with 99% of primary production coming from South Africa and Russia. This study employs dynamic material flow analysis (

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
