BACKGROUND Food adulteration remains a major global concern. DNA fingerprinting has several advantages over chemical and morphological identification techniques. DNA microarray-based fingerprinting techniques have not been used previously to detect adulteration involving dried commercial samples of closely related species. Here we report amplification of low-level DNA obtained from dried commer...

In the current network-based computing world, where number of interconnected devices grows exponentially, their diversity, malfunctions, and cybersecurity threats are increasing at same rate. To guarantee correct functioning performance novel environments such as Smart Cities, Industry 4.0, or crowdsensing, it is crucial to identify capabilities (e.g., sensors, actuators) detect potential misbe...

Sequence-dependent electrophoresis (SDE) fingerprinting techniques such as denaturing gradient gel electrophoresis (DGGE) have become commonplace in the field of molecular microbial ecology. The success of the SDE technology lays in the fact that it allows visualization of the predominant members of complex microbial ecosystems independent of their culturability and without prior knowledge on t...

Graph databases that emerge from several relevant scenarios (e.g., social networks, the Web) require powerful data management algorithms and techniques. A fundamental operation in graph data management is computing the similarity between two graphs. However, due to the large scale and high dimensionality of real graph databases, computing graph similarity becomes a challenging problem in real s...

In conventional DNA fingerprinting, hypervariable and repetitive sequences (minisatellite or microsatellite DNA) are detected with hybridization probes. As demonstrated here, these probes can be used as single primers in the polymerase chain reaction (PCR) to generate individual fingerprints. Several conventional DNA fingerprinting probes were used to prime the PCR, yielding distinctive, hyperv...

RF fingerprinting is proposed as a means of providing an additional layer of security for wireless devices. A masquerading or impersonation attacks can be prevented by establishing the identity of wireless transmitter using unique transmitter RF fingerprint. Unique RF fingerprints are attributable to the analog components (digital-to-analog converters, band-pass filters, frequency mixers and po...
