Surface-Enhanced Nitrate Photolysis on Ice
(2015)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 ... -
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
(2015)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
(2015)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 ... -
Non local spatial and angular matching : enabling higher spatial resolution diffusion MRI datasets through adaptive denoising
(2016)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 ... -
Macrodynamics of economics: a bibliometric history
(2016)A history of specialties in economics since the late 1950s is constructed on the basis of a large corpus of documents from economics journals. The production of this history relies on a combination of algorithmic methods ... -
There should not be any mystery: a comment on sampling issues in bibliometrics
(2016)A research unit wants to assess whether its publications tend to be more cited than academic publications in general. This research unit could be anything from a lonesome researcher to a national research council sponsoring ... -
Time-domain numerical model of substation conductor span subjected to short-circuit loading
(2017)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(2015)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 ... -
Testing steel lattice towers with a hybrid (numerical/ experimental) method
(2016)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
(2016)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(2016)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 ... -
Comparative effects of adaptation on layer II-III and layer V-VI neurons in cat V1
(2016)Abstract: V1 is fundamentally grouped into columns that descend from layers II–III to V–VI. Neurons inherent to visual cortex are capable of adapting to changes in the incoming stimuli that drive the cortical plasticity. ... -
Electrophysiological and firing properties of neurons: categorizing soloists and choristers in primary visual cortex
(2015)Abstract: Visual processing in the cortex involves various aspects of neuronal properties such as morphological, electrophysiological and molecular. In particular, the neural firing pattern is an important indicator of ... -
Light-induced valley polarization in interacting and nonlinear Weyl semimetals
(2017)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 ... -
Calibration de protocoles d’études de cohorte et calcul de puissance pour l’estimation d’un risque sanitaire en épidémiologie des rayonnements ionisants
(Université de Sherbrooke, 2018)Au sein du Laboratoire d’ÉPIDémiologie des rayonnements ionisants (LEPID) de l’Institut de Radioprotection et de Sûreté Nucléaire (IRSN), des études de cohorte sont mises en place puis régulièrement mises à jour afin ... -
Modélisation et mise en place d’une assistance cognitive personnalisée pour la qualité du sommeil et la déambulation nocturne
(Université de Sherbrooke, 2019)Les troubles du sommeil des personnes âgées atteintes de maladie neurodégénérative entraine des comportements d’errance nocturne qui diminuent leur qualité de vie et peuvent avoir des conséquences sur leur sécurité et ... -
Bacillus subtilis and Bacillus velezensis population dynamic and quantification of spores after inoculation on ornamental plants
(2020)Abstract: Bacillus subtilis and Bacillus velezensis are used in organic agriculture as an alternative to chemical pesticides to fight against phytopathogen organisms. These Gram-positive soil-dwelling bacteria are able to ... -
Competition between alkenes in intramolecular ketene-alkene [2 + 2] cycloaddition: What does it take to win?
(2005)Abstract: In the course of developing a new synthetic methodology using ketenes in sequential cycloaddition steps, we were faced with a competition problem with molecules containing a ketene tethered to more than one ... -
Addition of tethered nonaromatic carbon nucleophiles to chemoselectively activated amides
(2005)Abstract: In an effort to develop new ways of synthesizing polycyclic alkaloids, we successfully added silyl enol ethers, allylsilanes, and enamines to iminium ions generated from amides. Because of their higher oxidation ... -
Intramolecular additions of various π-nucleophiles to chemoselectively activated amides and application to the synthesis of (±)-tashiromine
(2006)Abstract: Vilsmeier-Haack type cyclizations proved to be particularly efficient for generating parts of the polycyclic cores of many alkaloids, although only monocyclizations have so far been reported. With the goal ...
