Lecanicillium aphanocladii: a biocontrol agent against insect pests and phytopathogens

Pest Management Science, EarlyView.
Recent research findings on the biocontrol potential of Lecanicillium aphanocladii fungus against insect‐pests and plant diseases were highlighted. This review indicates that several L. aphanocladii strains show great potential to be developed as multipurpose biocontrol agents active against several insect‐pests, plant diseases and plant parasitic ...

Linear Parameter-Varying Control of a Ducted Fan Engine [PDF]

, 1995
Parameter-dependent control techniques are applied to a vectored thrust, ducted fan engine. The synthesis technique is based on the solution of Linear Matrix Inequalities and produces a controller which achieves specified performance against the worst ...

The X-shooter Spectral Library (XSL): I. DR1. Near-ultraviolet through optical spectra from the first year of the survey [PDF]

, 2014
We present the first release of XSL, the X-Shooter Spectral Library. This release contains 237 stars spanning the wavelengths 3000--10200 \AA\ observed at a resolving power $R \equiv \lambda / \Delta\lambda \sim 10000$. The spectra were obtained at ESO's

Output Feedback Design for Parameter Varying Systems Subject to Persistent Disturbances and Control Rate Constraints

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper develops a framework for designing output feedback controllers for constrained linear parameter‐varying systems that experience persistent disturbances. We specifically propose an incremental parameter‐varying output feedback control law to address control rate constraints, as well as state and control amplitude constraints.

Stent patency and outcome of TIPS through the left versus the right portal branches

The Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background Our purpose is to compare the stent patency and clinical outcome of trans-jugular intra-hepatic porto-systemic shunt (TIPS) through the left branch portal vein (TIPS-LPV) to the standard TIPS through the right branch (TIPS-RPV).

Formal Safety and Security Assessment of an Avionic Architecture with Alloy

, 2014
We propose an approach based on Alloy to formally model and assess a system architecture with respect to safety and security requirements. We illustrate this approach by considering as a case study an avionic system developed by Thales, which provides ...

Wildness of the problems of classifying two-dimensional spaces of commuting linear operators and certain Lie algebras [PDF]

, 2017
For each two-dimensional vector space $V$ of commuting $n\times n$ matrices over a field $\mathbb F$ with at least 3 elements, we denote by $\widetilde V$ the vector space of all $(n+1)\times(n+1)$ matrices of the form $\left[\begin{smallmatrix}A&*\\0&0 ...

Periodic Scenario Trees: A Novel Framework for Robust Periodic Invariance and Stabilization of Constrained Uncertain Linear Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This work proposes a new framework for stabilizing uncertain linear systems and for determining robust periodic invariant sets and their associated control laws for constrained uncertain linear systems. Necessary and sufficient conditions for stabilizability by periodic controllers are stated and proven using finite step Lyapunov functions for

Lymphotropic polyomavirus and Merkel cell polyomavirus in patients infected with HIV or hepatitis B or C virus

New Microbes and New Infections
Background: LPV and MCV emerge as recent additions to the Polyomaviridae family, capable of inducing important infections. Studies have suggested the presence of LPV in human populations, with potential involvement in central nervous system (CNS ...
