Quantifying the presence of a neutron in the paths of an interferometer

Physical Review Research, 2022
It is commonly assumed that no accurate experimental information can be obtained on the path taken by a particle when quantum interference between the paths is observed.

A mutation operator self-adaptive differential evolution particle swarm optimization algorithm for USV navigation

Frontiers in Neurorobotics, 2022
To keep the global search capability and robustness for unmanned surface vessel (USV) path planning, an improved differential evolution particle swarm optimization algorithm (DePSO) is proposed in this paper.

Comparison of unitary transforms [PDF]

, 2002
We analyze the problem of comparing unitary transformations. The task is to decide, with minimal resources and maximal reliability, whether two given unitary transformations are identical or different.

Novel Algorithms of 3D Particle Tracking Velocimetry Using a Tomographic Reconstruction Technique

Journal of Fluid Science and Technology, 2012
New algorithms of 3D particle tracking velocimetry (3D PTV) based on a tomographic reconstruction approach have been developed and tested by using synthetic images of unsteady 3D flows.

Alignment of cryo-EM movies of individual particles by optimization of image translations

, 2015
Direct detector device (DDD) cameras have revolutionized single particle electron cryomicroscopy (cryo-EM). In addition to an improved camera detective quantum efficiency, acquisition of DDD movies allows for correction of movement of the specimen, due ...

Stochastic modelling of particle aggregation [PDF]

, 2015
Aggregation is an inter-particle process which involves a multitude of different physicochemical mechanisms. In the present work, particles in the nano-scale are considered, with such concentration that renders their direct simulation as individual ...

Long-lived states of oscillator chain with dynamical traps

, 2004
A simple model of oscillator chain with dynamical traps and additive white noise is considered. Its dynamics was studied numerically. As demonstrated, when the trap effect is pronounced nonequilibrium phase transitions of a new type arise.

Three-Dimensional Reconstruction of Individual Particles in Dense Dust Clouds: Benchmarking Camera Orientations and Reconstruction Algorithms

Journal of Imaging, 2019
In dusty plasmas, determining the three-dimensional particle positions and trajectories of individual particles is often required. This paper benchmarks two approaches capable of reconstructing the trajectories of particles in three dimensions.
