Mechanical watches are complex and sensitive systems that have to maintain a faultless precision over their lifetime. However, this precision can be altered by disturbances occurring during the functioning time, such as friction, lubricant drying, or wear, ...
Gravity currents are density-driven flows that are able to transport high amounts of sediment and are responsible of great geomorphic changes. Moreover they can have severe repercussions on the environment since they are conveyors of substances, e.g. pollu ...
The tip leakage vortex (TLV), which develops in the clearance between the blade tip and the casing of axial turbomachines, appears in many industrial applications, such as air transportation, space rockets and hydraulic machines. In the latter, cavitation ...
Earthquakes are natural phenomena that cause ground shaking and damage to people and infrastructures. Despite significant progress achieved in understanding how earthquakes start, propagate, and arrest, many aspects of their physics and mechanics remain no ...
The pioneering paper 'Optical rogue waves' by Solli et al (2007 Nature 450 1054) started the new subfield in optics. This work launched a great deal of activity on this novel subject. As a result, the initial concept has expanded and has been enriched by n ...
Recent advances in biology and neuroscience have elucidated pathways in which visible light initiates a signaling process, via the eye, responsible for activating direct and indirect biological responses. While the full impact of unnatural light patterns ...
In this article, we combine experiments and theory to investigate the transport properties of anisotropic hematite colloidal rotors that dynam ically assemble into translating clusters upon application of a rotating magnetic field. The applied field exerts ...
The workshop on mapping with drones for natural and built environments has been organised in the framework of the Brazilian-Swiss Joint Research Programme (BSJRP), which supports research activity and academic cooperation. The Ecole polytechnique fédérale ...
In situ scanning transmission electron microscopy enables observation of the domain dynamics in ferroelectric materials as a function of externally applied bias and temperature. The resultant data sets contain a wealth of information on polarization switch ...
Advances in data acquisition—through more powerful supercomputers for simulation or sensors with better resolution—help scientists tremendously to understand natural phenomena. At the same time, however, it leaves them with a plethora of data and the chall ...
