Current Source Density Reconstruction from Incomplete Data
We propose two ways of estimating current source density (CSD) from measurements of voltage on a Cartesian grid with missing recording points using the inverse CSD method. The simplest approach is to substitute local averages (LA) in place of missing data. A more elaborate alternative is to estimate a smaller number of CSD parameters than the actual number of recordings and to take the least-sq...
متن کاملTemporal Resolution and Motion Artifacts in Dual-Source Cardiac CT and Single-Source CT with Iterative Reconstruction
The temporal resolution (TR) of an image has become an important property in computed tomography (CT) when examining organs whose motion can not be stopped for the duration of the CT scan, such as in cardiac CT. In this context, “higher TR” conventionally means that the raw data from which a given image was reconstructed was measured within a shorter time interval than the raw data of a similar...
متن کاملReconstruction from a single diffraction pattern of azimuthally projected electron density of molecules aligned parallel to a single axis.
Diffraction from the individual molecules of a molecular beam, aligned parallel to a single axis by a strong electric field or other means, has been proposed as a means of structure determination of individual molecules. As in fiber diffraction, all the information extractable is contained in a diffraction pattern from incidence of the diffracting beam normal to the molecular alignment axis. Th...
متن کاملDetermining the WIMP mass from a single direct detection experiment
The energy spectrum of nuclear recoils in Weakly Interacting Massive Particle (WIMP) direct detection experiments depends on the underlying WIMP mass (strongly for light WIMPs, weakly for heavy WIMPs). We discuss how the accuracy with which the WIMP mass could be determined by a single direct detection experiment depends on the detector configuration and the WIMP properties. In particular we ex...
متن کاملModeling and Simulation of a Molecular Single-Electron Transistor
In this paper, to understand the concept of coupling, molecule density of states that coupled to the metal electrodes will be explained then, based on this concept, a weak and strong coupling for the molecules attached to the metal electrodes will be described. Capacitance model is used to explore the connection of addition energy with the Electron affinity and the ionization energy of the mole...
