A numerical model of spontaneous decay continuously monitored by a distant detector of emitted particles is constructed. It is shown that there is no quantum Zeno effect in such quantum measurement if the interaction between emitted particle and detector is short-range and the mass of emitted particle is not zero. PACS numbers: 03.65.Bz

A general method is presented for determining and correcting nonlinear position detector responses in single particle tracking as used in three-dimensional scanning probe microscopy based on optical tweezers. The method uses locally calculated mean square displacements of a Brownian particle to detect spatial changes in the sensitivity of the detector. The method is applied to an optical tweeze...

Background: : Due to the difficulties of locally obtaining ZnS(Ag), preliminary investigation of the radioluminescence characterization of Zinc oxide (ZnO) for alpha particle detection was performed. Materials and Methods: The scintillation properties of ZnO films were tested using alpha sources                &nbsp...

A Particle Flow Algorithm (PFA) with the minimized dependence on the detector geometry is presented. Current PFA implementation includes procedures of the track reconstruction, calorimeter clustering, and individual particle reconstruction and is meant as a tool for the optimization of the International e + e − Linear Collider detector.

The Alpha Magnetic Spectrometer (AMS), to be installed on the International Space Station (ISS) in 2008, is a cosmic ray detector with several subsystems, one of which is a proximity focusing Ring Imaging Čerenkov (RICH) detector. This detector will be equipped with a dual radiator (aerogel+NaF), a lateral conical mirror and a detection plane made of 680 photomultipliers and light guides, enabl...

We consider the asymptotic evolution of a relativistic spin-1 2 particle. i.e. a particle whose wavefunction satisfies the Dirac equation with external static potential. We prove that the probability for the particle crossing a (detector) surface converges to the probability , that the direction of the momentum of the particle lies within the solid angle defined by the (detector) surface, as th...

• Compute particle weights from linear SVM score of extended HOG features [2] • Baseline: Features computed for each particle • Enhancement: Sliding window detector on feature pyramid for fast re-detection after occlusions, failure detection, and to find the best negative training examples in each frame • Particles get SVM score from detector response • Sliding-window-based measurement model is...
