Rapid adaptation of a polygenic trait after a sudden environmental shift
, 2017 Although a number of studies have shown that natural and laboratory populations initially well-adapted to their environment can evolve rapidly when conditions suddenly change, the dynamics of rapid adaptation are not well understood.

Experimental investigation on the dynamic characteristics and transverse vibration instabilities of transmission belts [PDF]
, 2008 Serpentine belt drives are often used in front end accessory drive of automotive engine. Dynamic characteristics of belts play an important role in the behavior of such transmission and are inputs of simulation software. Moreover, free belt spans exhibit

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]
, 2013 To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

Frequency and time fault diagnosis methods of power transformers
Measurement Science Review, 2018 The authors describe experimental and theoretical analyses of faults of power transformer winding. Faults were caused by mechanical effect of short-circuit currents. Measurements of transformer were carried out in high-voltage laboratory.
