Chiral interaction in capillary electrophoresis can be modeled using pK values, mobilities of analytes, and their formation constants with the chiral selector. An existing steady-state simulation program for CE (HPCESIM) was recently extended with a chiral submenu involving the chiral parameters listed above. These were experimentally determined in both our laboratories for mandelic acid and te...

We have selected and spatially separated the two conformers of 3-aminophenol (C6H7NO) present in a molecular beam. Analogous to the separation of ions based on their mass-to-charge ratios in a quadrupole mass filter, the neutral conformers are separated based on their different mass-to-dipole-moment ratios in an ac electric quadrupole selector. For a given ac frequency, the individual conformer...

A heat-load shutter capable of frequencies from one to several tens of kHz and window times from 10 micros up to 1 ms is described. In the current configuration the water-cooled shutter absorbs approximately 99% of the heat generated by the white beam. It has been successfully used for extended periods synchronized with a Jülich pulse-selector operating at 946 Hz. The temperature of the pulse-s...

A novel fault phase selector for double-circuit transmission lines is presented. The fault type is determined with the superimposed components and steady state components of fault voltage. According to the determined fault type, auxiliary criteria based on the magnitude and phase difference of fault phase current is applied to judge whether inter-line fault happens or not. If inter-line fault h...

This project focuses on applying neural networks to the classification of biological state based on gene expression data. In order to take advantage of the non-linear classification abilities of neural networks, a genetic algorithm is employed as a “wrapper” feature selector. Results indicate that the genetic algorithm effectively identifies features that allow successful neural network trainin...

The breakdown (BD) of one-selector-one-resistor memory cells incurs increasing crosstalk and power consumption in the cross-point array. In this work, failed bit pruning (FBP) operation selectors is presented to cope with side effects due BD cells. First, FBP concept its requirements on device parameters presented. Then wide existence demonstrated by investigating five different materials. Amon...

The elements of a finite nonempty partially ordered set are exposed at independent uniform times in [0,1] to a selector who, at any given time, can see the structure of the induced partial order on the exposed elements. The selector’s task is to choose online a maximal element. This generalizes the classical linear order secretary problem, for which it is known that the selector can succeed wit...
