Evaluation of strengthening techniques of traditional masonry buildings: case study of a four-building aggregate [PDF]
Increasing appraisal of the durability, conservation state, and changeable use and function of old buildings in urban centers relies a great deal on the structural safety evaluation of vertical load capacity and the ability to resist horizontal forces ...

Sociological Forum, EarlyView.ABSTRACT Healthcare in the United States is defined by profit motives and economic inequality, yet medical providers and organizations are also guided by moral values such as a commitment to patient well‐being. How have sociologists made sense of this apparent contradiction?

The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins
Terra Nova, EarlyView.ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Uncertainty Propagation and Feature Selection for Loss Estimation in Performance-based Earthquake Engineering [PDF]
, 2004 This report presents a new methodology, called moment matching, of propagating the uncertainties in estimating repair costs of a building due to future earthquake excitation, which is required, for example, when assessing a design in performance-based ...

Yantu gongcheng xuebaoAs the dislocation of active fault is the main factor leading to the failure of the tunnels crossing the fault, it is essential for the seismic design to evaluate the dislocation resistance performance of the tunnels crossing active fault zones. However,

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
