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.

Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image on a substrate, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. At least one of the source images includes image content in the form of a textured image. When the rendered composite image is subjected to illumination by one of the narrow band illuminants for which a source image was encoded, the textured image in the recovered source image becomes visually detectable.

Systems for spectral multiplexing of source images including a textured source image to provide a composite image, for rendering the composite image, and for spectral demultiplexing of the composite image

The troublesome weed, jimson weed (Datura stramonium L.) is a plant with both poisonous and medicinal properties. The neurotoxicity is attributed to the presence of tropane alkaloids which contain a methylated nitrogen atom (N-CH 3 ) and include the anticholinergic drugs atropine, and scopolamine, as well as the narcotic cocaine. A wide range of medicinal values of this plant have contributed in scientific field and also in ethnomedicine. The phytochemical, ethnomedicinal and toxicological works on D.stramonium has given a better assessment and information of this particular plant. The present paper presents an exclusive review work on the neurotoxic properties of D. stramonium.

Mechanism of HIV-1 RNA dimerization in the central region of the genome, and significance for viral evolution

Fingerprinting of audio-visual content using digital watermarks is an effective means of determining the originators of unauthorized copies and fighting piracy in digital distribution networks. In particular, watermarks embedded within the content help trace the traitor responsible for the piracy. A group of users may, however, collude and collectively escape identification by creating an average of their individually watermarked copies that appears unwatermarked. We propose a novel collusion-resilience mechanism, wherein the host signal is warped randomly prior to watermarking. As each copy undergoes a distinctive warp, collusion through averaging either yields low-quality results or requires substantial computational resources to undo random warps. The proposed method is independent of the watermarking scheme used and does not impose any restrictions on the watermark signal that are required by some collusion resistant watermarking schemes. We demonstrate the effectiveness of this approach on digital images.
