BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205000 DESCRIPTION A 15-year-old boy reported with extra teeth in his upper left and right back region since 4–5 years. Medical and family history did not reveal any related positive findings. On detailed intraoral examination, supernumerary teeth were found dis...

We propose what we believe to be a novel method for highly accurate three-dimensional (3D) angle measurement based on propagation vector analysis of digital holography. Three-dimensional rotations in space can be achieved by use of a CCD camera and a multifacet object, which reflects an incident wave into different directions. The propagation vectors of the reflected waves from the object can b...

We introduce a bifocal imaging method that enables three-dimensional (3D) tracking of both fluorescent and nonfluorescent particles. We accomplish this by simultaneously imaging a focused plane, for in-plane position (x,y), and a defocused plane, for out-of-plane position (z), of a molecule using a single CCD camera. We applied our method to several systems including in vivo melanosome tracking...

We study the statistical properties of recordings that contain time-dependent positions of a bead trapped in optical tweezers. Analysis of such a time series indicates that the commonly accepted model, i.e., the autoregressive process of first-order, is not sufficient to fit the data. We show the presence of a first-order moving average part in the dynamical model of the system. We explain the ...
