Diaryliodonium salts are versatile arylating agents but generally feature poor atom economy. In this issue of Chem, Olofsson and co-workers describe a novel chemoselective SNAr reaction that sets up second in situ arylation incorporates the iodoarene component cascade with excellent The N- O-based functionalities, producing diarylamine ether structures essential to many biologically active mole...

electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...

BACKGROUND The HIV cascade of care (cascade) is a comprehensive tool which identifies attrition along the HIV care continuum. We executed analyses to explicate heterogeneity in the cascade across key strata, as well as identify predictors of attrition across stages of the cascade. METHODS Using linked individual-level data for the population of HIV-positive individuals in BC, we considered th...

Cascade is a program static analysis tool developed at New York University. Cascade takes as input a program and a control file. The control file specifies one or more assertions to be checked together with restrictions on program behaviors. The tool generates verification conditions for the specified assertions and checks them using an SMT solver which either produces a proof or gives a concre...

We investigate the response of energy flux in isotropic turbulence to step-function like perturbation in external forcing at large length scales. From both physical experiments and direct numerical simulations, we measured the evolution of the Eulerian velocity structure functions, such as DLL(r), DNN (r), before and after the perturbation in forcing. In both cases, we observed the cascade of t...

We consider shell models that display an inverse energy cascade similar to two-dimensional turbulence (together with a direct cascade of an enstrophylike invariant). Previous attempts to construct such models ended negatively, stating that shell models give rise to a "quasiequilibrium" situation with equipartition of the energy among the shells. We show analytically that the quasiequilibrium st...
