Behaviour of precast concrete beams prestressed with CFRP strands

Građevinar, 2016
Corrosion presents a serious problem in severe marine environments, especially for bridges. This paper explores the use of carbon fibre reinforced polymer (CFRP) strands for prestressing precast concrete girders.

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, Volume 43, Issue 6, Page 3868-3892, September 2026.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Corrosion and Strength Behaviors in Prestressed Tendon under Various Tensile Stress and Impressed Current Conditions

Advances in Materials Science and Engineering, 2017
Corrosion occurs more rapidly under high tensile stress and this leads to several problems like degradation of serviceability and structural performance in PSC (prestressed concrete) structures. In this paper, impressed current method, so-called ICM, was

Molecular insights and translational opportunities to enhance heat tolerance in rice

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Heat stress is an increasingly serious threat to rice (Oryza sativa L.) productivity, yet the genetic and regulatory architecture underlying thermotolerance remain poorly resolved and fragmented across studies. Earlier research focused on individual pathways or specific developmental stages; however, recent advances now support an integrated ...

Prestressing and Self-Healing of Fiber-Reinforced and Ultra-High-Performance Concrete Using Shape Memory Alloys

Buildings
A large number of existing studies show that fiber-reinforced concrete (FRC) and ultra-high-performance concrete (UHPC) have improved crack resistance relative to conventional concrete, but there is limited research on further advancing the structural ...

Bayesian Inference of Fault Slip Heterogeneity and Overlap: Application to 2019 Ridgecrest Earthquakes and Afterslip

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Fault slip occurs in both seismic and aseismic styles with spatial variability across scales, yet non‐unique source inference limits our ability to resolve slip complexity and dynamics. Here we evaluate the effect of spatial smoothing regularization in Bayesian frameworks by comparing an unregularized (BUR) approach that samples distributed ...
