The Cyclic Stability of the Superelasticity in Quenched and Aged Ni44Fe19Ga27Co10 Single Crystals
The effect of aging (at 773 K for 1 h) on the cyclic stability of superelasticity was studied in preliminarily quenched (after annealing at 1448 K for 1 h) Ni44Fe19Ga27Co10 [001]-oriented single crystals.

Accurate assessment of the stator-winding insulation condition in high-voltage machines is crucial for safe operation. Conventional evaluation methods treat the insulation as spatially uniform and provide only a holistic assessment; in practice, however,

AGING EFFECTS ON SHIP STRUCTURAL INTEGRITY
The most important degradation effects of ship structures are corrosion and fatigue cracks. Both of these aging effects have clear consequences of increasing the level of stresses and degrading the strength of ship structures for almost all relevant ...

There is increasing evidence that tendons are heterogeneous and take advantage of structural mechanisms to enhance performance and reduce injury. Fascicle-sliding, for example, is used by energy-storing tendons to enable them to undergo large extensions while protecting the fascicles from damage.

Cardiac ventricular performance in the appropriate‐ for‐gestational age and small‐for‐gestational age fetus: relation to regional cardiac non‐uniformity and peripheral resistance [PDF]
AbstractObjectiveTo investigate the relationship between parameters of diastolic function, loading conditions and remodeling of the left ventricle in the appropriate‐for‐gestational age and small‐for‐gestational age fetus.MethodsTwo‐dimensional echocardiographic left ventricular images were digitized in 24 appropriate‐for‐gestational age and 14 small ...

The GET pathway is a major bottleneck for maintaining proteostasis in Saccharomyces cerevisiae
A hallmark of aging in a variety of organisms is a breakdown of proteostasis and an ensuing accumulation of protein aggregates and inclusions. However, it is not clear if the proteostasis network suffers from a uniform breakdown during aging or if some ...

AbstractBiodiversity is expected to change in response to future global warming. However, it is difficult to predict how species will track the ongoing climate change. Here we use the fossil record of planktonic foraminifera to assess how biodiversity responded to climate change with a magnitude comparable to future anthropogenic warming.
