Hybrid metaheuristic optimization-based solution for reactive power dispatch in dynamic power systems

open access: yesAin Shams Engineering Journal
Optimal Reactive Power Dispatch (ORPD) is essential for maintaining voltage stability and minimizing power losses in dynamic power systems. However, frequent load changes and uncertain generation sources, such as photovoltaics (PV) and wind turbines (WT),

a randomized, open, multicenter phase III trial of lenalidomide/dexamethasone versus lenalidomide/dexamethasone plus subsequent autologous stem cell transplantation and lenalidomide maintenance in patients with relapsed multiple myeloma [PDF]

open access: yes, 2016
Background Despite novel therapeutic agents, most multiple myeloma (MM) patients eventually relapse. Two large phase III trials have shown significantly improved response rates (RR) of lenalidomide/dexamethasone compared with placebo/dexamethasone in ...

Ligand-Free Palladium-Catalyzed Oxyarylation of Dihydronaphthal­enes and Chromenequinone with o-Iodophenols and 3-Iodolawsone in PEG-400: An Efficient Synthesis of 5-Carbapterocarpans and Pterocarpanquinones [PDF]

open access: yes, 2015
Dihydronaphthalenes were oxyarylated with o-iodophenols, in PEG-400 at 140 or 170 °C, leading regio- and stereoselectively to 5-carbapterocarpans. By using Pd(OAc)2 (5–10 mol%) as precatalyst and Ag2CO3 (1.1 equiv) as base (conditions A), products were ...
