"Quand nous serons à mille, nous ferons une croix". Le contre-espionnage, un nouveau terrain de coopération entre gendarmes et policiers à la fin du …
2013
International audience; Si le travail respectif comme la collaboration des policiers et des gendarmes en matière de policejudiciaire et de maintien de l’ordre sont désormais mieux connus, leur coopération dans le contre-espionnagedemeure encore largement ignorée. En dépit de représentations mutuelles antagonistes, lalutte contre les menées étrangères montre l’entente entre les forces de l’ordre et révèle l’émergenced’un système national de sécurité intérieure, en partie structuré par cette défiance commune. Letravail des forces de l’ordre met également en lumière la xénophobie traversant alors une sociétéfrançaise voyant en chaque étranger, notamment d’Outre-Rhin, un espion possible.
Adopting encryption to protect confidential data in public clouds: A review of solutions, implementation challenges and alternatives
2015
A shift towards use of public cloud services is ongoing and more and more enterprises will start to use them in the near future. As public cloud services certainly promise to deliver many benefits, this new way of delivering services also introduces new types of risks. Due to the NSA’s surveillance programs, non-US enterprises need to reassess the risks of public cloud services provided by US companies and look for available solutions to protect their confidential data transferred and stored in the cloud. Encryption is seen as a solution to help enterprises full fill the requirements related to security and privacy, but is often challenging to implement. Encryption has its own security prob…

The subject of this article is the authorization of intelligence services in preventing and combating the offences of espionage and terrorism. It describes the regulations of the Second Polish Republic regarding espionage, a draft Act on Intelligence Activities, the rule of law and opportunism, and most importantly new regulations under the anti-terrorism law

Temporal genetic structure in a poecilogonous polychaete: the interplay of developmental mode and environmental stochasticity
2014
Background: Temporal variation in the genetic structure of populations can be caused by multiple factors, including natural selection, stochastic environmental variation, migration, or genetic drift. In benthic marine species, the developmental mode of larvae may indicate a possibility for temporal genetic variation: species with dispersive planktonic larvae are expected to be more likely to show temporal genetic variation than species with benthic or brooded non-dispersive larvae, due to differences in larval mortality and dispersal ability. We examined temporal genetic structure in populations of Pygospio elegans, a poecilogonous polychaete with within-species variation in developmental m…

Folate targeted coated SPIONs as efficient tool for MRI
2017
The development of more sensitive diagnostic tools allowing an early-stage and highly efficient medical imaging of tumors remains a challenge. Magnetic nanoparticles seem to be the contrast agents with the highest potential, if properly constructed. Therefore, in this study, hybrid magnetic nanoarchitectures were developed using a new amphiphilic inulin-based graft copolymer (INU-LAPEG-FA) as coating material for 10-nm spinel iron oxide (magnetite, Fe3O4) superparamagnetic nanoparticles (SPION). Folic acid (FA) covalently linked to the coating copolymer in order to be exposed onto the nanoparticle surface was chosen as the targeting agent because folate receptors are upregulated in many can…
Data from: DNA methylation and potential for epigenetic regulation in Pygospio elegans
2016
Transitions in developmental mode are common evolutionarily, but how and why they occur is not understood. Developmental mode describes larval phenotypes, including morphology, ecology and behavior of larvae, which typically are generalized across different species. The polychaete worm Pygospio elegans is one of few species polymorphic in developmental mode, with multiple larval phenotypes, providing a possibility to examine the potential mechanisms allowing transitions in developmental mode. We investigated the presence of DNA methylation in P. elegans, and, since maternal provisioning is a key factor determining eventual larval phenotype, we compared patterns of DNA methylation in females…
