this commentary to the editorial of hajizadeh argues that the economic, social and health consequences of legalizing cannabis in canada will depend in large part on the exact stipulations (mainly from the federal government) and on the implementation, regulation and practice of the legalization act (on provincial and municipal levels). a strict regulatory framework is necessary to minimize the ...

Soil organic matter has positive consequences eht rof quality and productivityof soil and also environment, agricultural and biological sustainability and conservation ofbiodiversity and soil. Organic matter plays an important role in the physical and chemicalprocesses of soil and thus, it is of a great effect on the spectral characteristics of soil. Thisstudy was done in order to develop the m...

In this report, I have studied a simplification, suggested by Viterbi [1], to the BCJR algorithm for the bitwise MAP decoder for convolutional and turbo codes. The simplifications involve reduction in both computational complexity and memory requirements, using, first, a good approximation to the metric update rules for BCJR algorithm and, second, a scheduling algorithm to reduce memory require...

This Letter reports on the experimental implementation of the quantum baker's map via a three bit nuclear magnetic resonance quantum information processor. The experiments tested the sensitivity of the quantum chaotic map to perturbations. In the first experiment, the map was iterated forward and then backward to provide benchmarks for intrinsic errors and decoherence. In the second set of expe...

The National Map is the U.S. Geological Survey’s (USGS) next-generation topographic mapping product. This concept aims to achieve a more effective and regenerative public mapping program through local participation, inter-agency data sharing, and integration. This ambitious endeavor faces many significant challenges to its implementation, however. The Federal Geographic Data Committee (FGDC) wa...
