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

San 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;

China‐Europe Railway Express and Innovation by Chinese Manufacturing Firms: An Analysis Based on Technology Spillovers From Differentiated Products

Asia &the Pacific Policy Studies, Volume 13, Issue 3, September 2026.
ABSTRACT Amid global supply chain restructuring, this study examines how the China‐Europe Railway Express transitions from logistics connectivity to innovation empowerment. Using its launch as a quasi‐natural experiment, we find that the China‐Europe Railway Express significantly accelerates innovation in Chinese manufacturing firms, especially for ...

Safety soft sensor development for pilot‐scale ilmenite electric arc furnace using long short‐term memory‐based architecture

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4702-4718, September 2026.
Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.

The effects of scientific uncertainty and values trade‐offs on flow management decisions for an endangered fish

Ecosphere
Consumptive use of freshwater is of concern in many estuarine ecosystems, and various frameworks have been used to prescribe environmental flows to benefit native species.

Output Quality, Productivity, and Demand: Evidence from the Chinese Steel Industry

The RAND Journal of Economics, Volume 57, Issue 3, Page 784-807, Autumn (Fall) 2026.
ABSTRACT Unobserved objective output quality complicates the analysis of firm productivity and demand because higher‐quality products entail higher costs but offer greater consumption benefits. Using a panel of firms with output quality data, we decompose quantity‐based productivity into fundamental productivity and the costs of quality, and separate ...

Tidal Influence on Environmental DNA Detections for Delta Smelt

San Francisco Estuary and Watershed Science
Current ecological conditions in the San Francisco Estuary are considered inhospitable to many native estuarine species, and have placed the endemic Delta Smelt (Hypomesus transpacificus) at serious risk. Programmatic monitoring regimes conducted by government agencies are insufficient for associating Delta Smelt occurrence with relevant habitat ...

Delta Smelt: Life History and Decline of a Once-Abundant Species in the San Francisco Estuary

San Francisco Estuary and Watershed Science, 2016
doi: http://dx.doi.org/10.15447/sfews.2016v14iss2art6This paper reviews what has been learned about Delta Smelt and its status since the publication of The State of Bay-Delta Science, 2008 (Healey et al. 2008). The Delta Smelt is endemic to the upper San

Neighboring Gulf Killifish (Fundulus grandis) Populations Differ in Their Plastic and Genetic Responses to Salinity Fluctuations

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Coastal development can alter the salinity fluctuations experienced by tidal creek systems. Understanding how resident organisms, such as the Gulf killifish, respond to these changes is critical, as development along the coastline is projected to triple in the coming decades.

Evaluation and Interpretation of Genetic Effective Population Size of Delta Smelt from 2011–2014

San Francisco Estuary and Watershed Science, 2017
https://doi.org/10.15447/sfews.2017v15iss2art5Delta Smelt have collapsed demographically, but little is known about their current genetic status. We used 12 microsatellite loci to evaluate two measures of the effective population size (Ne) of Delta ...

Locating Little Larvae: Environmental DNA Methods Can Detect a Rare Fish Species Under Field Estuarine Conditions

Environmental DNA
Rare species are difficult to monitor using traditional methods, making them excellent candidates for environmental DNA (eDNA) monitoring. The larval life stages of Delta Smelt (Hypomesus transpacificus) and Longfin Smelt (Spirinchus thaleichthys) are ...
