Study on the Hydrodynamic Effects of Bridge Piers Under Velocity-Type Pulse Ground Motion Based on Different Characteristic Periods

open access: yesApplied Sciences
This study was based on a target spectrum (GB183062015) and synthesized different characteristic periods, pulse ground motions, and non-pulse ground motions utilizing EQsignal v1.2.1 software. It also investigated the dynamic behaviors of bridge piers in

Shaking Table Tests of Curved Bridge considering Bearing Friction Sliding Isolation

open access: yesShock and Vibration, 2016
Specific to severe damage to curved bridges in earthquakes caused by the excessive force of the fixed bearings and piers, a new seismic design method on curved bridges considering bearing friction sliding isolation is proposed in this paper.

Pursuing patents for their own sake: How the investment discourse shapes patent quality and quantity

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract Patent systems worldwide face criticisms over declining patent quality and increasing patent quantity. While most research focuses on strengthening examination rigour, this article turns attention to relatively underexplored patenting incentives.

Study on Horizontal Displacement Response of Bridge Pier Tops Under Bidirectional Seismic Excitation

open access: yesShock and Vibration
The near-field vertical seismic action not only causes an increase in the pressure endured by the bridge pier but also exerts a remarkable influence on the horizontal deformation at the top of the pier.

Sustainable and Seismically Resilient Confined Masonry: Global Progress in Research and Design Practice

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
Modern confined masonry (CM) construction consists of masonry walls confined by reinforced concrete (RC) tie‐columns and tie‐beams. When built correctly, CM buildings have shown good performance in earthquake's shaking. Even though CM construction has been practised for almost a century in some Latin American countries, its use and standardisation are ...

Quantification of the Effect of Bridge Pier Encasement on Headwater Elevation Using HEC-RAS

open access: yesHydrology, 2019
The deterioration of bridge substructure is a serious concern across the United States. The pier encasement is one of the most common practices for repairing and strengthening the bridge substructure. It is a rehabilitation process of existing pile piers

Feasibility of Field Oral Health Assessment in Free‐Ranging Rhesus Macaques (Macaca mulatta) on Cayo Santiago

open access: yesAmerican Journal of Primatology, Volume 88, Issue 10, October 2026.
A 5‐day field study on Cayo Santiago shows that standardized dental exams, oral sampling, and portable radiography can be performed in free‐ranging rhesus macaques. Tongue swabs yielded enough protein for inflammatory profiling, whereas gingival fluid samples did not, enabling scalable studies of oral health and aging.

Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 13, Page 3264-3284, 25 October 2026.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.
