A highly sensitive microarray system for detecting protein-protein interactions has been developed. This method was successfully applied to analyze the interactions of heme-regulated phosphodiesterase from Escherichia coli (Ec DOS). To immobilize (His)6-Tag fused Ec DOS, anti-(His)6-Tag monoclonal antibody (anti-(His)6-Tag mAb) was initially immobilized on the solid surface, and (His)6-Tag fuse...

In this paper, we simulated Collusion and Network partition DoS attacks using GlomoSIm (GLobal MObile information system SIMulator). The network with 36 nodes in grid pattern was chosen. Throughput analysis with and without DoS attack was carried out for varying number of nodes. The importance of fairness in MAC layer is also justified through the results obtained. Keywords— DoS, Collusion, Par...

BACKGROUND In spite of extensive efforts to improve in vitro oocyte maturation, the obtained results are not very efficient. This study was conducted to assess impacts of cAMP elevating agents and alpha lipoic acid (ALA) on in vitro oocyte maturation and fertilization. METHODS Mouse germinal vesicle (GV) oocytes were categorized into cumulus denuded oocytes (DOs; n=896) and cumulus oocyte com...

Sensors have varied constraints, which makes the network challenging for communicating with its peers. In this paper, an extension to the security of physical layer of a predictive sensor network model using the ant system is proposed. The Denial of Service (DoS) attack on sensor networks not only diminishes the network performance but also affects the reliability of the information making dete...

The SH2 domain-containing phosphotyrosine phosphatase Corkscrew (CSW) is an essential component of the signaling pathway initiated by the activation of the sevenless receptor tyrosine kinase (SEV) during Drosophila eye development. We have used genetic and biochemical approaches to identify a substrate for CSW. Expression of a catalytically inactive CSW was used to trap CSW in a complex with a ...

We show in microwave measurements and computer simulations that the contribution of each eigenchannel of the transmission matrix to the density of states (DOS) is the derivative with angular frequency of a composite phase shift. The accuracy of the measurement of the DOS determined from transmission eigenchannels is confirmed by the agreement with the DOS found from the decomposition of the fie...

The local, eigenfunction-weighted acoustic phonon density of states (DOS) tensor is calculated for a model substrate consisting of a semi-infinite isotropic elastic continuum with a stress-free surface. On the surface, the local DOS is proportional to the square of the frequency v, as for the three-dimensional Debye model, but with a constant of proportionality that is considerably enhanced com...

Denial-of-Service (DoS) attacks aim to affect availability of applications. They can be executed using several techniques. Most of them are based upon a huge computing power that is used to send a large amount of messages to attacked applications, e.g. web services. Web services apply parsing technologies to process incoming XML messages. This enlarges the amount of attack vectors since attacke...

BACKGROUND Diffuse oesophageal spasm (DOS) is a potential cause of intermittent chest pain and/or dysphagia. In the past, the diagnosis of DOS has relied on criteria obtained from standard oesophageal manometry (more than one simultaneous contraction in a series of 10 wet swallows with the rest being peristaltic). As symptoms are intermittent, however, 24 hour manometry may well be more suited ...

Um problema importante na f́ısica concerne a origem dos grandes eventos na dinâmica de sistemas complexos, tais como terremotos, epidemias, extinção de espécies e quebras nas bolsas de valores. Aqui revisamos recentes avanços sugerindo que os grandes eventos na dinâmica dos mercados financeiros surgem dos efeitos de memória de longo alcance. Estudamos as distribuições nos mercados financeiros me...
