A growing number of studies focusing on microplastics (plastic particles smaller than 5 mm) show this issue affects all environmental matrices and compartments, and suspicions grow as to their toxicity. In this context, the Commission Internationale pour l ...

We experience the world as a seamless stream of percepts. However, intriguing illusions and recent experiments suggest that the world is not continuously translated into conscious perception. Instead, perception seems to operate in a discrete manner, just ...
Systems and methods for tracking interacting objects may acquire, with a sensor, and two or more images associated with two or more time instances. A processor may generate image data from the two or more images. The processor may apply an extended Probabi ...
Optical trapping was used for decades in biotechnology for a broad range of applications. It can be used for remote manipulation, application of pico-Newton forces and even study DNA processes. Nevertheless, optical trapping setups can be cumbersome. In or ...
We prove that iterated Whitehead products of length. (n+1) vanish in any value of an n-excisive functor in the sense of Goodwillie. We compare then different notions of homotopy nilpotency, from the Berstein-Ganea definition to the Biedermann-Dwyer one. Th ...
Reliable determination of the basic physical properties of hot emission-line binaries with Roche-lobe filling secondaries is important for developing the theory of mass exchange in binaries. It is a very hard task, however, which is complicated by the pres ...
We prove that balanced loss-gain distributions provide an elegant path towards realizing loss-free unidirectional cloaks for objects much larger than the wavelength. By coating a scatterer with an ultrathin metasurface with balanced loss and gain, such as ...
Here, we present a numerical post-processing method for removing the effect of anti-symmetric residual aberrations in high-resolution transmission electron microscopy (HRTEM) images of weakly scattering 2D-objects. The method is based on applying the same ...
In some computer vision applications, matching between shapes and colors are required. There are lots of similarity measures for shapes, especially curves, but as far as we know there are not many that deal with shapes and colors at the same time. In this ...
Humans have an incredible capacity to learn properties of objects by pure tactile exploration with their two hands. With robots moving into human-centred environment, tactile exploration becomes more and more important as vision may be occluded easily by o ...
