There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

The lion's share of bacteria in various environments cannot be cloned in the laboratory and thus cannot be sequenced using existing technologies. A major goal of single-cell genomics is to complement gene-centric metagenomic data with whole-genome assemblies of uncultivated organisms. Assembly of single-cell data is challenging because of highly non-uniform read coverage as well as elevated levels of sequencing errors and chimeric reads. We describe SPAdes, a new assembler for both single-cell and standard (multicell) assembly, and demonstrate that it improves on the recently released E+V-SC assembler (specialized for single-cell data) and on popular assemblers Velvet and SoapDeNovo (for multicell data). SPAdes generates single-cell assemblies, providing information about genomes of uncultivatable bacteria that vastly exceeds what may be obtained via traditional metagenomics studies. SPAdes is available online ( http://bioinf.spbau.ru/spades ). It is distributed as open source software.

Steganographic methods attempt to insert data in multimedia signals in an undetectable fashion. However, these methods often disrupt the underlying signal characteristics, thereby allowing detection under careful steganalysis. Under repeated embedding, disruption of the signal characteristics is the highest for the first embedding and decreases subsequently. That is, the marginal distortions due to repeated embeddings decrease monotonically. We name this general principle as the principle of diminishing marginal distortions (DMD) and illustrate its validity in the audio domain using a morphological distortion metric. The principle of DMD is used to derive a steganalysis tool that detects the presence of hidden messages in uncompressed audio files. Detailed analysis and experimental results are provided for the detection of spread spectrum watermarking and stochastic modulation steganography.

Morphological steganalysis of audio signals and the principle of diminishing marginal distortions

A method for automatically classifying a printed image, includes scanning the printed image; selecting an n by n block of pixels from the scanned image; calculating an array of DCT coefficients of the pixel block, wherein the array of calculated DCT coefficients are representative of spatial frequency and spatial orientation of the pixel block; comparing the DCT coefficients with an array of predetermined values, wherein the array of predetermined values are indicative of different image marking processes used to produce printed images; and determining an image marking process used to create the printed image based on the comparison of the DCT coefficients with the array of predetermined values. The array of DCT coefficients may be sampled into a feature set and the feature set provided to a neural network to output the determined image marking process.

India is a great country that is recognised for its rich culture and medicinal plants. Most of the people in India is reliant on herbal plant for their therapeutic needs. The present review will focus on Therapeutic plants from India along with its medicinal use. Various medicinal plants have already proved their significance with curing diseases including bacteriological infections and some life threating serious diseases. Medicinal plants are rich in antioxidant and proved best as antimicrobial agents. Herbal drugs are achieving popularity as compared to allopathic drugs the reasons includes adverse effects of man-made antibiotics, prompt surge in contagious diseases, resistance of drug in microbes. Herbal plants shows slow recovery, still a great population is using it because it showed no side effects and low resistance in microbes. Antimicrobial status of various herbal plants has been reported. Therapeutic plants work as a potent antimicrobial. Herbal plants are used for its medicinal purpose throughout the world as herbal plants provide base material for various effective drugs. A great number of herbal plants has been used as drug in the form of crude extracts and extensively used for their therapeutic possessions. Huge number of plants has been examined for antimicrobial possessions, but still majority of plants have not been examined adequately. So, the present review will focus on some of the selected medicinal plant along with its antimicrobial status. Key words : Medicinal plants, antimicrobial agent, infections, herbal drugs, antifungal.

Indian medicinal plants as an effective antimicrobial agent

A level-embedded lossless compression method for continuous-tone still images is presented. Level (bit-plane) scalability is achieved by separating the image into two layers before compression and excellent compression performance is obtained by exploiting both spatial and inter-level correlations. A comparison of the proposed scheme with a number of scalable and non-scalable lossless image compression algorithms is performed to benchmark its performance. The results indicate that the level-embedded compression incurs only a small penalty in compression efficiency over non-scalable lossless compression, while offering the significant benefit of level-scalability.
