Capacity of Prestressed Concrete Containment Vessels with Prestressing Loss [PDF]

open access: yes, 2001
Reduced prestressing and degradation of prestressing tendons in concrete containment vessels were investigated using finite element analysis of a typical prestressed containment vessel. The containment was analyzed during a loss of coolant accident (LOCA) with varying levels of prestress loss and with reduced tendon area.

Extracellular fluid viscosity influences the mechanics and migration of MDA‐MB‐231 cells in a macromolecule‐dependent manner

open access: yesThe FEBS Journal, EarlyView.
Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.

Analysis of the Prestressing Loss Influence in Prefabricated Concrete Bridges Based on a Drop Weight Impact Method

open access: yesBuildings
The prestress loss of prefabricated continuous beam bridges directly affects their stress state and operating conditions. Excessive prestress loss can lead to increased mid span deflection of the main beam, cracking of the web and bottom plates, reduced ...

Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2760-2780, September 2026.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

open access: yesJournal 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.

Snap-through behaviour of a bistable structure based on viscoelastically generated prestress

open access: yes, 2017
A novel form of shape-changing bistable structure has been successfully developed through the use of viscoelastically generated prestress. Bistability is achieved through pairs of deflecting viscoelastically prestressed polymeric matrix composite (VPPMC)

Molecular insights and translational opportunities to enhance heat tolerance in rice

open access: yesThe 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 ...

Development of multi-functional anchorage support dynamic-static coupling performance test system and its application

open access: yesInternational Journal of Mining Science and Technology
In underground engineering with complex conditions, the bolt (cable) anchorage support system is in an environment where static and dynamic stresses coexist, under the action of geological conditions such as high stresses and strong disturbances and ...

Full‐scale Shaking Table Tests on a 10‐story Steel Moment‐resisting Frame Building with Buckling‐restrained Braces

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2356-2378, August 2026.
ABSTRACT In February 2023, a comprehensive series of shaking table tests were conducted at the E‐Defense facility, the world's largest three‐dimensional earthquake simulator, on a full‐scale 10‐story steel moment‐resisting frame supplemented with BRBs.

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

open access: yesJournal 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 ...
