Flow manipulation in sweeping microchip capillary electrophoresis (CE) is complicated by the free liquid communication between channels at the intersection, especially when the electroosmotic flows are mismatched in the main channel. Sweeping in traditional CE with cationic micelles is an effective way to concentrate anionic analytes. However, it is a challenge to transfer this method onto micr...

Fast sweeping methods were developed in the literature to efficiently solve static Hamilton-Jacobi equations. This class of methods utilize the Gauss-Seidel iterations and alternating sweeping strategy to achieve fast convergence rate. They take advantage of the properties of hyperbolic partial differential equations (PDEs) and try to cover a family of characteristics of the corresponding Hamil...

A sweeping automaton is a two-way deterministic finite automaton which makes turns only at the endmarkers. Sipser [12] has proved that one-way nondeterministic finite automata can be exponentially more succinct in sizes than sweeping automata. In this paper, we propose a technique based on the work in [6] for establishing lower bounds on the size of sweeping automata. We show that Sipser’s tech...

Interaction between microbially induced calcium carbonate precipitation (MICP) and compaction procedures to stabilise raw soil materials has been studied with the aim of producing earthen engineering structures. Initial tests optimise MICP in aqueous medium selected soils were performed. finally applied assess medium-size elements. The main result was that sandy should be compacted before irrig...

in the current investigation a novel nano hybrid adsorbent mcm-41/n-(3-trimethoxysilyl)-propyl)diethylenetriamine (mcm-41/tmspdeta) was prepared and was characterized using dls (dynamic light scattering), fourier transform infrared (ftir), x-ray diffraction (xrd), brunauer–emmett–teller (bet) analytical techniques and transmission electron microscopy (tem). the synthesized mcm-41/tmspdeta adsor...

The geost constraint has been proposed to model and solve discrete placement problems involving multi-dimensional boxes (packing in space and time). The filtering technique is based on a sweeping algorithm that requires the ability for each constraint to compute a forbidden box around a given fixed point and within a surrounding area. Several cases have been studied so far, including integer li...

This paper describes a simple means for embedding a checksum within a FITS header, providing a mechanism for later verifying the integrity of the FITS le. The method uses ASCII coded 32-bit 1's complement arithmetic to force the checksum of each FITS HDU to zero. This technique requires no extension of the FITS standard to be used by any given project, in fact the technique may be used to zero ...

Probing the surface states in Bi2Se3 via electronic transport measurements is difficult due to significantly larger numbers of bulk carriers. Herein, we report contribution both and on measured photocurrent at room temperature electrical low temperatures an epitaxial thin film intrinsic capped with a high K dielectric, Al2O3. The continuously increases when gate voltage swept toward negative si...
