Anchorage System Contribution to Post‐Tensioned Bridge Collapse

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Water quality in reference watersheds in the United States: A compilation and analysis of small watershed data

open access: yesJournal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract The natural background contribution from grasslands and forest lands is important to consider in research and management to address the contribution of agricultural, industrial, and urban lands to water quality degradation. To our knowledge, no study has compiled and analyzed reference water quality from small reference grasslands and forests ...

Benthic Macroinvertebrate Recovery After Wastewater Treatment Plant Upgrades: Implications for Biomonitoring

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 824-836, May 2026.
ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and

Reducing the Threshold of Organic Polariton Lasers by Active Layer Micropatterning and Lateral Confinement

open access: yesSmall Structures, Volume 7, Issue 5, May 2026.
The study demonstrates the miniaturization of organic polariton VCSELs based on BSBCz. Using ultra‐thin shadow masks, isolated microcavities as small as 5 µm are fabricated. These devices achieved record‐low lasing fluences (0.21 µJ/cm2), far below reference devices.
