The origins of DNA replication of the genome (209 kbp) of Chilo iridescent virus (CIV), which is circularly permuted and terminally redundant, were identified. The defined genomic library of CIV, which represents 100% of DNA sequences of the viral genome (e.g., all 32EcoRI CIV DNA fragments), was used for transfection ofChoristoneura fumiferana insect cell(More)
Watermarking has been suggested as a means to improve security of biometric systems or to add additional functionalities to such systems. We experimentally investigate the impact of applying a set of blind robust watermarking schemes on the recognition performance of two iris recognition algorithms. We find that different watermarking schemes result in a(More)
The genetic characterization of a serologically Hantaan-like virus but of unknown origin (termedDX) was carried out by molecular cloning and nucleotide sequencing of the corresponding cDNA of the viral S RNA segment. The S RNA was found to be 1765 nucleotides long with 3′ and 5′ termini being complementary for 24 bases. The virus messenger-sense RNA(More)
Watermarking has been suggested as a means to improve security of biometric systems. We discuss application scenarios for resolving various security issues in this context. As embedding watermarks changes biometric data, degraded recognition performance using such data may be expected. We experimentally investigate the impact of applying a set of blind(More)
Infectious herpes simplex virus type 1 (HSV-1) recombinants were constructed by inserting the cDNA sequence of the human immunodeficiency virus type 1 (HIV-1)gag gene (from nucleotide position 675 [SacI] to 3859 [Asp 718] of the cDNA sequences of HIV-1 strain BH-10) within the DNA sequences of theBamHI DNA fragment B of the genome of an apathogenic HSV-1(More)
L'irradiation UV d'une solution de sulfocyanate d'ammonium, glycine et fer dans l'eau de mer artificielle a produit des microsphères semblables à des cellules douées d'activité catalytique péroxidasique. La glycine a augmenté l'activité catalytique du fer, comme cela purrait s'être produit au cours de l'evolution dans la première étape de cette réaction de(More)
