Methods for analyzing the resistance of large woodlands (such as Siberian taiga forests) to insect attacks based on remote sensing data are proposed. As an indicator woodland’s resistance, we suggest a function normalized difference vegetative index (NDVI) susceptibility changes in land surface temperature (LST). Both NDVI and LST obtained via TERRA/AQUA satellite system. This was calculated sp...

Recent advances in our understanding of induced responses in plants and their regulation, brought about by a revolution in molecular biology, have re-focused attention on the potential exploitation of endogenous resistance mechanisms for crop protection. The future goal of crop biotechnology is thus to engineer a durable, multimechanistic resistance to insect pests through an understanding of t...

In digital watermarking robustness is still a challenging problem if di erent sets of attacks need to be tolerated simultaneously In this paper we deal with this problem by using an integrated solution of side informed embedding moment normalization and content dependent watermarks First a new image watermarking method designed based on the concept of communications with side information is pro...

To identify plant defense responses that limit pathogen attack, Arabidopsis eds mutants that exhibit enhanced disease susceptibility to the virulent bacterial pathogen Pseudomonas syringae pv maculicola ES4326 were previously identified. In this study, we show that each of four eds mutants (eds5-1, eds6-1, eds7-1, and eds9-1) has a distinguishable phenotype with respect to the degree of suscept...

Digital fingerprinting is a means to offer protection to digital data by which fingerprints embedded in the multimedia are capable of identifying unauthorized use of digital content. A powerful attack that can be employed to reduce this tracing capability is collusion. In this paper, we study the collusion resistance of a fingerprinting system employing Gaussian distributed fingerprints and ort...
