Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate
Chemistry – A European Journal, EarlyView.A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Release of multicomponent pheromones from porous fibres
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.

Asymptotic pole assignment by learning
, 2000 This paper solves the exact pole assignment problem for the single-input stochastic systems with unknown coefficients under the controllability assumption which is necessary and sufficient for the arbitrary pole assignment for systems with known ...

Gradient-Based Approach to Solve Optimal Periodic Output Feedback Control Problems
, 1998 We discuss the numerical solution of the output feedback optimal periodic control problem by using a gradient search based optimization approach. Extension of this approach to the simultaneous stabilization of periodic multimodels is also considered. For

Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Ecography, EarlyView.Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

A Local Parametrization of the State-Feedback Matrices in the Pole Assignment Problem
Given a controllable system $(F,G)$, a local parametrization is obtained for the set of feedback gain matrices $K$ such that the state matrix, $F+GK$, of the closed loop system is in a prescribed similarity class. It is shown that this set can be endowed with the structure of a differentiable manifold whose dimension is also computed.
