Replication and active partition of integrative and conjugative elements (ICEs) of the SXT/R391 family : the line between ICEs and conjugative plasmids is getting thinner
Integrative and Conjugative Elements (ICEs) of the SXT/R391 family disseminate multidrug resistance among pathogenic Gammaproteobacteria such as Vibrio cholerae. SXT/R391 ICEs are mobile genetic elements that reside in the ...
Cyclic Di-GMP Riboswitch-Regulated Type IV Pili Contribute to Aggregation of Clostridium difﬁcile
Clostridium difﬁcile is an anaerobic Gram-positive bacterium that causes intestinal infections with symptoms ranging from mild diarrhea to fulminant colitis. Cyclic diguanosine monophosphate (c-di-GMP) is a bacterial ...
Surface-Enhanced Nitrate Photolysis on Ice
Heterogeneous nitrates photolysis is the trigger for many chemical processes occurring in the polar boundary layer and is widely believed to occur in a quasi-liquid layer (QLL) at the surface of ice. The dipole forbidden ...
Non local spatial and angular matching : enabling higher spatial resolution diffusion MRI datasets through adaptive denoising
Diffusion magnetic resonance imaging (MRI) datasets suffer from low Signal-to-Noise Ratio (SNR), especially at high b-values. Acquiring data at high b-values contains relevant information and is now of great interest for ...
Light-induced valley polarization in interacting and nonlinear Weyl semimetals
It has been recently predicted that the interplay between Coulomb interactions and Berry curvature can produce interesting optical phenomena in topologically nontrivial two-dimensional insulators. Here, we present a theory ...
Testing steel lattice towers with a hybrid (numerical/ experimental) method
Abstract : The analysis of transmission line steel lattice towers is usually performed with linear numerical methods. However, the actual behaviour of bolted lattice towers is complex and may be highly affected by different ...
Review of advanced modelling methods for lattice steel towers
Abstract : The analysis of transmission line steel lattice towers is usually performed with simplified linear numerical methods. However, the actual behaviour of bolted lattice towers is complex and may be affected by ...
Experimental testing of a new hysteretic damper for base isolated bridges
Other titre : Resilient infrastructure = Infrastructures résilientes
Abstract: An experimental procedure was developed to implement a simplified design method of supplemental dampers for isolated highway bridges. For seismically base-isolated bridges subjected to an earthquake, the principal ...
Time-domain numerical model of substation conductor span subjected to short-circuit loading
Abstract: "Short-circuit faults in electrical power networks result in substantial electromagnetic forces on conductor cables as well as supporting structures. These dynamic forces often have a leading impact on the ...
Simplified design method for energy dissipating devices in retrofitting of seismically isolated bridges
Other titre : Building on our growth opportunities = Miser sur nos opportunités de croissance
Abstract: This paper presents an innovative simplified method for the optimum design of seismically isolated bridges incorporating energy dissipating devices. For an isolated bridge subjected to an earthquake, the deformation ...
