Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

Structural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Arc Splitting and Back‐Arc Spreading Evolution: The Control of Slab Dehydration and Melting Processes

Geochemistry, Geophysics, Geosystems
Subduction zones are integral to Earth's deep water cycle, influencing magmatism, lithosphere dynamics and seismicity. They often exhibit development of extensional processes in the upper plate, which may lead to volcanic arc splitting and backarc basin ...

Post‐earthquake field assessment and damage correlation of elevated reinforced concrete water tanks in Kahramanmaras/Elbistan, Türkiye

Structural Concrete, EarlyView.
Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...

Mantle conductivity structure beneath eastern China using 3-D geomagnetic depth sounding

Frontiers in Earth Science
The distribution of water in the mantle plays a critical role in deep earth dynamic processes, including plate subduction, earthquake generation, and magmatic activity.

Ionothermal Synthesis of Cu(Sb2Se3)[AlCl4] and Cu5(Bi2Se3)6[AlCl4]5 : Monolayers of Sb2Se3 and Bi2Se3 Stabilized by Cu[AlCl4]

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Ionothermal synthesis in Lewis‐acidic ionic liquids (ILs) yields two new low‐dimensional pnictogen–selenide networks cocrystallized with Cu[AlCl4]. Both are narrow‐gap semiconductors that exhibit strong absorption throughout the visible range. Topochemical AlCl3 extraction triggers partial delamination, pointing to a viable route toward 2D derivatives.

Large-scale early cretaceous lower-crust melting derived adakitic rocks in NE China: implications for convergent bidirectional subduction and slab rollback

, 2019
Large volumes of Early Cretaceous adakitic rocks crop out in northeast China. In this paper, we summarize their spatial-temporal distribution and geochemical characteristics.

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

The RAND Journal of Economics, EarlyView.
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 ...

Revised classification of glaciofluvial landforms in the Finnish sector of the Fennoscandian Ice Sheet

Boreas, EarlyView.
Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

Axial muscle‐fibre orientations in larval zebrafish

Journal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.
