We investigate the problem of automatically labelling appearances of characters in TV or film material with their names. This is tremendously challenging due to the huge variation in imaged appearance of each character and the weakness and ambiguity of available annotation. However, we demonstrate that high precision can be achieved by combining multiple sources of information, both visual and ...

Digital microfluidic devices allow the manipulation of droplets between two parallel electrodes. These electrodes can act as mirrors generating a micro-cavity, which can be exploited for a droplet dye-laser. Three representative laser-dyes with emission wavelengths spanning the whole visible spectrum are chosen to show the applicability of this concept. Sub-microlitre droplets of laser-dye solu...

The surface acoustic waves (SAW) propagate inside the microdroplets resulting in kinetic and thermal impacts. drives fluid particles droplet while impact increases liquid’s temperature. This paper provides a comprehensive review of research investigations related to internal kinetics heating microdroplet caused by waves. main factors that affect convection heat transfer are piezoelectric materi...

The production of diffraction-quality crystals of Munc18c, a protein involved in regulating vesicular exocytosis in mammals, is reported. The diffraction resolution of Munc18c crystals was optimized by (i) cocrystallizing with a peptide fragment of the Munc18c functional binding partner syntaxin4, (ii) using nanolitre free-interface diffusion crystallization-screening chips and microlitre hangi...

Triolein (free from oleic acid) is emulsified in a solution of calcium /v-nitrophenolate with the aid of Thesit or Sterox-SE. As a measure of enzyme activity, the decrease in extinction in the emulsion, which is proportional to the hydrogen ion concentration, is measured continuously at 436 nm with a light path of 0.5 cm. The reaction temperature is 25°C and the time of measurement is 10 min. T...
