Comparative study of minutiae selection methods for digital fingerprints.

Biometric systems are more and more used for many applications (physical access control, e-payment, etc.). Digital fingerprint is an interesting biometric modality as it can easily be used for embedded systems (smartcard, smartphone, and smartwatch).

Logical Attacks and Countermeasures for Fingerprint On-Card-Comparison Systems.

Digital fingerprints are being used more and more to secure applications for logical and physical access control. In order to guarantee security and privacy trends, a biometric system is often implemented on a secure element to store the biometric reference template and for the matching with a probe template (on-card-comparison). In order to assess the performance and robustness against attacks of these systems, it is necessary to better understand which information could help an attacker successfully impersonate a legitimate user.

Highlighting of quorum sensing lux genes and their expression in the hydrothermal vent shrimp Rimicaris exoculata ectosymbiontic community. Possible use as biogeographic markers.

Rimicaris exoculata is a caridean shrimp that dominates the fauna at several hydrothermal vent sites of the Mid-Atlantic Ridge. It has two distinct and stable microbial communities. One of these epibiontic bacterial communities is located in the shrimp gut and has a distribution and role that are poorly understood.

Y chromosome--a tool in infertility studies of Latvian population.

Unlabelled: Human Y chromosome is used as a tool in male infertility and population genetic studies. The aims of this research were to analyse the prevalence of Y chromosome microdeletions among infertile Latvian men, and to identify possible lineages of Y chromosome that may be at increased risk of developing infertility. A study encompassed 105 infertile men with different spermatogenic disturbances.

Mycotoxin fumonisin B1 increases intestinal colonization by pathogenic Escherichia coli in pigs.

Fumonisin B(1) (FB(1)) is a mycotoxin that commonly occurs in maize. FB(1) causes a variety of toxic effects in different animal species and has been implicated as a contributing factor of esophageal cancers in humans. In the present study, we examined the effect of dietary exposure to FB(1) on intestinal colonization by pathogenic Escherichia coli associated with extraintestinal infection.
