Double asymmetric hydrogenation of conjugated dienes: a self-breeding chirality route for C2 symmetric 1,4-diols
(Royal Society of Chemistry, 2019)
The synthesis and double asymmetric hydrogenation of (Z,Z)-1,3- diene-1,4-diyl diacetates is described. In this reaction C2/meso ratios up to 85 : 15 and enantioselectivities up to 97% ee have been achieved. As the ...

Explicit local multiplicative convolution of ℓ-adic sheaves
(European Mathematical Society, 2018)
We give explicit formulas for the local multiplicative convolution functors, which express the local monodromies of the convolution of two ℓ-adic sheaves on the torus Gm over the algebraic closure of a finite field in terms ...

Do stones modify the spatial distribution of fire induced soil water repellency? Preliminary data
(FUEGORED, 2013)
Water repellency is a property of many fire-affected soils that contributes to delayed wetting rates and shows many hydrological and geomorphological consequences. Fire-induced soil water repellency (SWR) may be modulated ...

Towards an OpenSource Logger for the Analysis of RPA Projects
(Springer, 2020)
Process automation typically begins with the observation of humans conducting the tasks that will be eventually automated. Sim ilarly, successful RPA projects require a prior analysis of the undergo ing processes which ...

Event-Driven Stereo Visual Tracking Algorithm to Solve Object Occlusion
(IEEE Computer Society, 2018)
Object tracking is a major problem for many computer vision applications, but it continues to be computationally expensive. The use of bio-inspired neuromorphic event-driven dynamic vision sensors (DVSs) has heralded ...

Spark Plasma Sintered Zirconia Ceramic Composites with Graphene-Based Nanostructures
(MDPI, 2018)
The addition of graphene-based nanostructures (GBNs) can improve the inherent fragility of ceramics and provide them with improved electrical and thermal conductivities. However, both the starting material (ceramic matrix ...

Role of precalcination and regeneration conditions on postcombustion CO2 capture in the Ca-looping technology
(Elsevier, 2014)
The Ca-looping (CaL) technology is already recognized as a potentially viable method to capture CO2 from postcombustion gas in coal fired power plants. In this process, CO2 is chemisorbed by CaO solid particles derived ...
