We present an Anti-Brownian Electrokinetic trap (ABEL trap) capable of trapping individual fluorescently labeled protein molecules in aqueous buffer. The ABEL trap operates by tracking the Brownian motion of a single fluorescent particle in solution, and applying a time-dependent electric field designed to induce an electrokinetic drift that cancels the Brownian motion. The trapping strength of...

The study of periodic solutions with constant sign in the Abel equation of the second kind can be made through the equation of the first kind. This is because the situation is equivalent under the transformation x 7→ x−1, and there are many results available in the literature for the first kind equation. However, the equivalence breaks down when one seeks for solutions with nonconstant sign. Th...

1. introduction intertextuality is a literature theory which has been based on bakhtine’s dialogism theory. it was firstly stated by juliet kristova. according to this theory each text is produced and read in a dialogue with other texts. intertextual criticism is a way of reading texts which signifies texts to each other rather than the real world. the hypotext, habil (abel) and qabil (cain), w...

The present paper is an attempt to apply the authors’ experiences of their work in validation of rule based systems (of. (Knauf, Abel, Jantke ~nd Gonzalez 1998). (Knauf, .lantke, Abd anti Philippow 1997), (Abel, Knauf, and Gonzalez 1996), (Abel Gonzalez 1997b), (Herrmann, .lantkc, and Knauf 1997), and (,lantke, Knauf and Abel 1997),t:.g.) c~e based systems. The objective of this work is both to...

Normal-hearing subjects show improved speech understanding when they wear conventional passive hearing protectors in noisy surroundings. In contrast, hearing-impaired subjects are at a disadvantage. Sound attenuation exacerbates the handicap from hearing loss (Abel et al., 1982). Level-dependent (active) hearing protectors which provide limited amplification of sounds below 85 dBA have the oppo...

 We examine permanent effects of monetary expansion in an economy where access to credit for financing consumption and investment is limited and consumers and firms are cash-constrained. The main difference between our model with those of Cooley-Hanson (1989) and Walsh (2003) is that investment, in addition to consumption, is subject to a cash-constraint. In this respect, our model is...

The Anti-Brownian Electrophoretic trap (ABEL trap) allows a user to trap and manipulate individual fluorescent molecules in solution. The heart of the ABEL trap is a microfluidic cell. In previous incarnations of the ABEL trap, the microfluidic cell was formed from a polydimethylsiloxane (PDMS) stamp and a glass coverslip. Here we present an improved microfluidic cell, made entirely out of glas...

This section deals with the definition, terminologies, and properties of the Sumudu transform and the Abel integral equation. In Section 2, solution of Abel integral equation is obtained by the application of the Sumudu transform, and in Section 3, the Sumudu transform is proved for distribution spaces, and the solution of Abel integral equation in the sense of distribution is obtained. The Sum...
