Effect of Crack Interval on Multiple Crack Propagation Behavior
Journal of Computational Science and Technology, 2007 In the authors' previous study, fatigue crack propagation tests were performed using four-point bending specimens with multiple parallel edge notches at regular intervals of 10 mm. In this study, similar tests were carried out using the specimens with crack intervals of 5 mm or 2.5 mm.

Estimation of Stress Intensity Factor by Using a New Fast Multipole Dual-Boundary Element Method
MathematicsCracks and defects are inevitable during the long-term use of structures. This study focuses on determining the stress intensity factors of multi-cracked structures by using a new fast multipole dual boundary element method.

Interaction of Multiple Cracks on Crack Propagation.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000 There is interaction among multiple cracks which are initiated in a plane surface by fatigue or environmentally assisted cracking. And it is observed that these cracks may coalesce as they approach each other. In this study, the interaction of multiple cracks with different relative locations and lengths was evaluated using a finite element method ...

Sensors, 2018 Due to a harsh working environment, micro-cracks in metal structures (e.g., airplane, oil/gas pipeline, hydro-turbine) often lead to serious accidents, so health monitoring of the metals is of great significance to ensure their safe operation.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Fatigue & Fracture of Engineering Materials & StructuresABSTRACT By exploiting the stress‐driven model, within the Euler–Bernoulli beam theory, a novel nonlocal analytical model is proposed in order to simulate the mechanical behavior of multiple edge–cracked nanobeams by taking into account the multiple cracks effects.
