A method to model the effect of pre-existing cracks on P-wave velocity in rocks
Journal of Rock Mechanics and Geotechnical Engineering, 2020 Crack closure is one of the reasons inducing changes of P-wave velocity of rocks under compression. In this context, a method is proposed to investigate the relationships among P-wave velocity, pre-existing cracks, and confining pressure based on the ...

Journal of Quantitative Description: Digital Media, 2021 In this study, we analyze for the first time newly available engagement data covering millions of web links shared on Facebook to describe how and by which categories of U.S. users different types of news are seen and shared on the platform. We focus on articles from low-credibility news publishers, credible news sources, purveyors of clickbait, and ...

Cracking “Open” Technology in Ecohydrology [PDF]
, 2020 In recent years, the adjective “open” has been applied to many aspects of scientific knowledge discovery and dissemination, including open-source software and hardware, open access journal articles, massive open online courses, and open data. Applying the term open to these entities emphasizes an intention for them to be accessible—a quality ...

Vibration Based - Crack Detection in Simplified Wind Turbine Blades Using Artificial Neural Networks [PDF]
Engineering and Technology Journal, 2014 Wind turbine blades are complicated components for inspection by non-destructive techniques because they are multi-layered, have variable thickness and are made of anisotropic materials. This paper proposes the use of Artificial Neural Networks (ANN) for

The Effects of Breathing Behaviour on Crack Growth of a Vibrating Beam
Shock and Vibration, 2018 The effects of breathing behaviour on the dynamic response and crack growth are studied through a cracked cantilever beam. The main goal is to reveal the coupling mechanism of dynamic response and crack growth by employing a plain single-degree-of ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Numerical Formulation on Crack Closing Effect In Buckling Analysis of Edge-Cracked Columns [PDF]
Journal of Rehabilitation in Civil Engineering, 2014 In this paper, buckling of simply supported column with an edge crack is investigated numerically and analytically. Four different scenarios of damage severities are applied to a column, open crack assumption and the effect of closing crack in stability ...

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.
