Selection of Ground Motion Intensity Measures in Fragility Analysis of a Mega-Scale Steel Frame Structure at Separate Limit States: A Case Study

Buildings, 2022
Selecting an appropriate ground motion intensity measure (IM) to estimate the aleatory uncertainty produced by ground motion variability is the first and crucial step in fragility analysis. The choice of IM is influenced not only by the structural system

An equation for the description of volume and temperature dependences of the dynamics of supercooled liquids and polymer melts [PDF]

, 2007
A recently proposed expression to describe the temperature and volume dependences of the structural (or alpha) relaxation time is discussed. This equation satisfies the scaling law for the relaxation times, tau = f(TV^g), where T is temperature, V the ...

Seismic Fragility Analysis of Bridge Pier

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Bridges are classified as lifeline structures as they need to be functional in an earthquake event. The performance-based analysis of the existing bridges is important for the stakeholders. Information on seismic performance in terms of fragility of existing bridges in the country can provide valuable information to the decision-

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Graphic Analysis of Osmotic Fragility of Erythrocytes

The Tohoku Journal of Experimental Medicine, 1976
A precise and highly reproducible method for analyzing the osmotic fragility of erythrocytes with a minute amount of blood (less than 10 mul) is described. The osmotic fragility curves are recorded with a coil planet centrifuge with accessories and a scanning photodensitometer.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Fragility and Seismic Performance Assessment of RC Frames Under Chinese and Pakistani Building Codes

CivilEng
The increasing integration of Chinese-engineered infrastructure in Pakistan under the China–Pakistan Economic Corridor (CPEC) necessitates a comparative evaluation of seismic resilience between the Chinese and Pakistani building codes. This study focused

Equilibrium Analysis, Banking, Contagion and Financial Fragility [PDF]

SSRN Electronic Journal, 2003
In this paper a general equilibrium model of an economy with incomplete markets (GEI) with money and default is examined. The model is a simplified version of the real world consisting of a non-bank private sector, banks, a central bank, a government and a regulator.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
