Abstract: A system for actively attenuating acoustic vibrations of a rail for rail traffic is provided including at least one sensor for detecting at least a vertical acoustic vibration of the rail, at least one actuator for exciting at least a vertical counter-vibration of the rail and at least one control unit communicatively connected to the at least one sensor and the at least one actuator for controlling the at least one actuator depending on the vibration detected by the sensor, the counter-vibration being adapted to destructively interfere with the detected vibration, and the at least one actuator being mechanically coupled to the rail and to a carrier element supporting the rail. Also provided is a carrier element for the system and a method for actively attenuating acoustic vibrations of a rail for rail traffic.

Abstract: An article of footwear includes an upper with an outer layer, an elastic layer, and a lacing system. The outer layer extends through a forefoot region, a midfoot region, and a heel region of the article of footwear and covers, at least partially, a medial side and a lateral side of the article of footwear. The elastic layer extends through the midfoot region and the heel region of the article of footwear and covers, at least partially, an instep region of the article of footwear. The lacing system extends, at least partially, across the instep region, and the outer layer includes a first elasticity and the elastic layer includes a second elasticity at least three times greater than the first elasticity.

Abstract: An article of footwear has an upper and a sole structure connected to the upper. The sole structure includes a casing having a bottom surface and a sidewall. The bottom surface and the sidewall define a cavity. A mixture is provided in the cavity that includes a binder and a plurality of plastic bodies.
