Past of a quantum particle: Common sense prevails

open access: yes, 2017
We analyze Vaidman's three-path interferometer with weak path marking [Phys. Rev. A 87, 052104 (2013)] and find that common sense yields correct statements about the particle's path through the interferometer.

Fuentes de variación en el tamaño de la semilla de la herbácea perenne Helleborus foetidus L. (Ranunculaceae)

open access: yesAnales del Jardín Botánico de Madrid, 2005
Seed size is one of the plant traits more thoroughly studied in plant sciences due to its pivoting ecological position between dispersal processes and emergence, survival and establishment of plant species. Frequently, most seed size variation is located

Kinetic Analysis of Discrete Path Sampling Stationary Point Databases

open access: yes, 2006
Analysing stationary point databases to extract phenomenological rate constants can become time-consuming for systems with large potential energy barriers. In the present contribution we analyse several different approaches to this problem.

Internet routing paths stability model and relation to forwarding paths [PDF]

open access: yes, 2013
Analysis of real datasets to characterize the local stability properties of the Internet routing paths suggests that extending the route selection criteria to account for such property would not increase the routing path length.

Path Contribution Analysis of Vibration Transfer Path Systems

open access: yesMathematical Problems in Engineering, 2019
To analyze the vibration characteristics of mechanical systems from the aspect of vibration transfer, two types of models for vibration transfer path systems were designed, which comprised three subsystems: excitation sources, transfer paths, and receivers.

Interactive cutting path analysis programs [PDF]

open access: yes
The operation of numerically controlled machine tools is interactively simulated. Four programs were developed to graphically display the cutting paths for a Monarch lathe, Cintimatic mill, Strippit sheet metal punch, and the wiring path for a Standard ...

Topological versus rheological entanglement length in primitive path analysis protocols

open access: yes, 2011
Primitive path analysis algorithms are now routinely employed to analyze entanglements in computer simulations of polymeric systems, but different analysis protocols result in different estimates of the entanglement length, N_e.
