The microfluidic probe (MFP) consists of a flat, blunt tip with two apertures for the injection and reaspiration of a microjet into a solution--thus hydrodynamically confining the microjet--and is operated atop an inverted microscope that enables live imaging. By scanning across a surface, the microjet can be used for surface processing with the capability of both depositing and removing materi...

Consider a scenario where radio base stations need to send data to users with wireless devices. Time is discrete and slotted into synchronous rounds. Transmitting a data item from a base station to a user takes one round. A user can receive the data item from any of the base stations. The positions of the base stations and users are modeled as points in Euclidean space. If base station b transm...

In order to explore the stability characteristics of hydropower station slope under different working conditions seismic action, three-dimensional dynamic finite element method was used analyze load with a probability exceeding 5% in 50 years, 2% 100 and 1% years reference period, through comparing response were obtained. The results showed that influence earthquake loads, ground motion would i...

Aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as SELEX. In the amplification and regeneration step of SELEX technique, dsDNA is conversed to ssDNA. Asymmetric PCR is one of the methods used for the generation of ssDNA. The purpose of this study was to design a random DNA library for selection of aptamers wit...

This paper considers the problem of detecting rogue base station in WiMAX/802.16 networks. A rogue base station is an attacker station that duplicates a legitimate base station. The rogue base station puzzles a set of subscribers who try to get service which they believe to be a legitimate base station. It may lead to disturbance in service. The strategy of attack depends on the type of network...
