Minimally invasive surgery (MIS), which typically involves endoscopic camera and laparoscopic instruments may seem to be the ideal surgical procedure for its apparent benefits. However, in comparison to open surgeries, the spatial and mechanical tool limit ...
Merging of electronics and photonics at subwavelength dimensions could potentially allow development of ultracompact electro-optic modulators and active optical interconnects. Here, we introduce a field-effect active plasmonic modulator where the metallic ...
Large shareholders may play an important role for firm performance and policies, but identifying this empirically presents a challenge due to the endogeneity of ownership structures. We develop and test an empirical framework that allows us to separate sel ...
The year 2011 having been proclaimed by UNESCO and IUPAP “International Year of Chemistry”, it seems fitting to have a close look at a physical chemistry instrument, the Polaristrobometer, an early form of polarimeter/saccharimeter, at its inventor, the Sw ...
When designing an audio processing system, the target tasks often influence the choice of a data representation or transformation. Low-level time-frequency representations such as the short-time Fourier transform (STFT) are popular, because they offer a me ...
Born near Zurich, Heinrich Wild studied physics and became in 1858 professor at the University of Bern. In 1868, he was called to the direction of the Central Physical (Meteorological) Observatory in Saint-Petersburg. During his 27 years in Russia, he was ...
Highly miniaturized low-power drop-coated metal-oxide gas sensors on polyimide foil are presented. Drop-coating of SnO2-based material was successfully achieved on transducers as small as 15 μm on polyimide, a substrate compatible with the printed electron ...
Precipitation is an important component of the Earth' water cycle and needs to be carefully monitored. Its large variability over a wide range of spatial and temporal scales must be taken into account. For example, hydrological models require accurate rain ...
Retrieval of the amplitude and phase of electromagnetic waves made digital holographic microscopy (DHM) capable of revealing morphological details at ultrahigh resolution in the order of a few nanometers only and precisely measuring the refractive index ac ...
In this paper we propose a novel method which is able to detect and separate audio-visual sources present in a scene. Our method exploits the correlation between the video signal captured with a camera and a synchronously recorded one-microphone audio trac ...
