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 ...

A state-of-the-art review of prestressed concrete tub girders for bridge structures

Journal of Infrastructure Preservation and Resilience, 2022
This paper presents a state-of-the-art review of prestressed concrete tub girders for bridge structures, which are a resilient solution to reduce the occurrence probability of disruptive events and to extend the longevity of built-environments. Technical

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

Advanced Science, Volume 13, Issue 40, 17 July 2026.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1924-1941, 25 July 2026.
ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Development Length Assessment of Bonded Post-Tensioning Slabs with Bulb-Shaped Dead end Anchorage

International Journal of Concrete Structures and Materials
The bond between prestressing strands and concrete within the dead-end zone of a post-tensioned concrete member significantly influences the effectiveness of the strand-concrete system.

A numerical study on seismic response of self-centring precast segmental columns at different post-tensioning forces

Latin American Journal of Solids and Structures
Precast bridge columns have shown increasing demand over the past few years due to the advantages of such columns when compared against conventional bridge columns, particularly due to the fact that precast bridge columns can be constructed off site and ...

Experimental Investigation of Progressive Collapse of Prestressed Concrete Frames after the Loss of Middle Column

Advances in Civil Engineering, 2020
Accidental loads such as explosion and vehicle impact could lead to failure of one or several load-bearing members in the structures, which is likely to trigger disproportionate progressive collapse of overall structures.

Single Cell Mechanics in Disease Progression

Small Science, Volume 6, Issue 7, July 2026.
Cells transmit distinct mechanical forces through ECM adhesion and cell–cell junctions and actomyosin‐generated traction forces are transmitted to the substrate through integrin‐based focal adhesions. Mechanical signals are further transmitted to the nucleus via the LINC complex, connecting the cytoskeleton to the nuclear lamina. These forces integrate

Mechanoregulatory Effects of Cell‐Scale Microwells on Epithelial Cell Phenotype

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
In small polycaprolactone microwells, A549 epithelial cells span well edges, in contrast to cells growing on flat substrates. Focal adhesion sites (yellow) concentrate at topographic boundaries, while cytoskeletal tension (magenta stress fibers) is transmitted to the nucleus (blue), reducing nuclear sphericity.

Comparison of Dynamic Characteristics of Prestressed and Reinforced Concrete Beams

Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2019
To determine the dynamic characteristics of bridges built with prestressed and reinforced concrete beams, thedynamic properties of such beams should be known. Prestressing force is applied to the prestressed concrete (PSC)beam, unlike reinforced concrete
