Cellular automata (CA) were introduced to provide a formal framework for investigating the behaviour of dynamic complex system in which time and space are discrete. They comprise an array of cells, where each cell can be in one of a finite number of possible states, which is updated synchronously in discrete time steps according to local transition rules (cell rules). A state of a cell at the n...

In this article we extend the elegant in-place Burrows-Wheeler transform (BWT) algorithm proposed by Crochemore et al. (Crochemore et al., 2015). Our extension is twofold: we first show how to compute simultaneously the longest common prefix (LCP) array as well as the BWT, using constant additional space; we then show how to build the LCP array directly in compressed representation using Elias ...

Driven by the demand of the bioelectronics market, many biosensors need to work in parallel or in a controllable way to achieve complicated biodetections, however the limited scale, speed, cost, complex signal processing, and bulky circuit routing problems prohibit the discrete biosensor solutions (Drummond et al., 2003). Nowaday biosensor are usually integrated on the same substrate to form bi...

Ocean acoustic noise can be processed efficiently to extract Green's function information between two receivers. By using noise array-processing techniques, it has been demonstrated that a passive array can be used as a fathometer [Siderius, et al., J. Acoust. Soc. Am. 120, 1315-1323 (2006)]. Here, this approach is derived in both frequency and time domains and the output corresponds to the ref...

The proposed method of processing of X-ray Computed Tomography (CT) data is based on its three-dimensional (3D) wavelet analysis, which allows for detection and localization of sudden changes in voxels of CT data array. The applied wavelet transform can be considered as filtering using sets of low-pass and high-pass filters over directions of a domain. The internal damage, which initially has d...

We praise the article by Mokhtari-Zaer et al. (2015) published in the Avicenna Journal of Phytomedicine on the effects of saffron on smooth muscle activity (Mokhtari-Zaer et al., 2015). It was a well-designed and interesting study on the therapeutic properties of Crocus sativus which is a precious plant cultivated in our country. We do believe that along with all other medicinal effects, saffro...

W e would like to thank Dr. Wong for the response to our article “No time to waste—the ethical challenges created by CRISPR”. Dr. Wong’s letter addresses a question about the relationship between biology and society: that “prevailing papers” on CRISPR-Cas9 rarely emphasize understanding the microbiological processes that make CRISPR-Cas9 an effective defensive mechanism. Instead, scientists and...
