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 …

I and i

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.

We consider camera self-calibration, i.e. the estimation of parameters for camera sensors, in the setting of a visual sensor network where the sensors are distributed and energy-constrained. With the objective of reducing the communication burden and thereby maximizing network lifetime, we propose an energy-efficient approach for self-calibration where feature points are extracted locally at the cameras and efficient descriptions for these features are transmitted to a central processor that performs the self-calibration. Specifically, in this work we use reduced-dimensionality quantized approximations as efficient feature descriptors. The effectiveness of the proposed technique is validated through feature matching, and epipolar geometry estimation which enable self-calibration of the network.

Recently, the synthesis of biodegradable adsorbents has attracted research interest. However, the use of a biodegradable material for adsorbing aqueous water contaminants can raise potential contradictions. Here, we describe aspects of biodegradable adsorbents intended for water purification that are perceived as contradictory. We present an insight into the research directions which may lead to a new breed of intelligent biodegradable adsorbents intended for industrial water remediation. Our discussions are organized as follows: (1) the nexus of adsorbent biodegradability and reusability is first explained, (2) an analysis of biodegradation of biodegradable adsorbents in microbe-rich environments is then presented, and (3) discussions are provided on the potential practical issues and the related research opportunities for using biodegradable adsorbents in real-world wastewaters. Based on these discussions, we inferred the following: (1) precise tuning of the biodegradability of biodegradable adsorbents is required prior to their real-world application, (2) biodegradable adsorbents capable of intelligent functionality and structure modulations are needed, and (3) protection-deprotection strategies should be built into biodegradable adsorbents. Achieving the latter objectives requires extensive investigation that will elucidate the interactions of microorganisms with the adsorbent and other constituents in different types of contaminated waters and the extent of the resulting biodegradation.
