We present a detection scheme for nanoscale particles based on the gradient force and torque near a tightly focused laser beam. The focus affects the path of nanoparticles passing by and a quadrant detector records the particle trajectory. A feedback system continuously adjusts the laser power and thereby prevents the particles from being trapped. Particle size and shape can be assessed by eval...

This is a bird’s eye view of T. E. Harris’ work on interacting particle systems and percolation, and of its impact on later work in probability theory and mathematical physics.

A multiuser detector for direct-sequence code-division multiple-access systems based on particle swarm optimization (PSO) algorithm is proposed. To work around potentially computational intractability, the proposed scheme exploits heuristics in consideration of both global and local exploration maximum likelihood (ML). Computer simulation demonstrates that the proposed detector offers near-opti...

Abstract The FY-3 satellites are China's second generation polar-orbiting meteorological satellites. high-energy particle detector (HEPD) suite of measures protons and electrons in different energy ranges. As the fifth satellite series, FY-3E continues to observe electrons. Here, we use Monte Carlo simulations based on GEANT4 code model electron calibrate electron/proton campaigns at Space Elec...

The electric eld distribution inside heavily irradiated silicon particle detectors is deduced using observations of particle and MIP signals. In these detectors particle signals are observed for both p and n side illumination even when the detector is only partially depleted . The observations indicate that the electric eld distribution within the detector has the contribution expected from a u...

I will present the latest results on particle identified spectra and two particle correlations at high transverse momentum measured with the STAR detector at RHIC. I will compare those measurements with the projected capabilities for the LHC using the ALICE detector. The effects of string fragmentation and quark recombination in the intermediate momentum range will be discussed in the context o...

The RICH detector in the hyperon beam experiment WA89 at the CERN-SPS is used for identiication of , K and p=p out of ?-N reactions. Methods for reduction of charged particle background in the detector are discussed. An algorithm for particle identiication was developed and tested on a sample of ! p decays. A separation of p and with 90% eeciency and a rejection by a factor of 10 or more at a m...

Searches for WIMP dark matter will in the near future be sensitive to solar neutrinos. Directional detection offers a method reject neutrinos and improve searches, but reaching that sensitivity with existing directional detectors poses challenges. We propose combined atomic/particle physics approach using large-volume diamond detector. candidate events trigger particle detector, after which spe...

We give a new proof for a Ray-Knight representation of Feller’s branching diffusion with logistic growth in terms of the local times of a reflected Brownian motion H with a drift that is affine linear in the local time accumulated by H at its current level. In [5], such a representation was obtained by an approximation through Harris paths that code the genealogies of particle systems. The pres...

We present a Spatio-temporal 2D Models Framework (STMF) for 2D-Pose tracking. Space and time are discretized and a mixture of probabilistic “local models” is learnt associating 2D Shapes and 2D Stick Figures. Those spatio-temporal models generalize well for a particular viewpoint and state of the tracked action but some spatiotemporal discontinuities can appear along a sequence, as a direct con...
