A 390-GHz Outphasing Transmitter in 28-nm CMOS
IEEE Journal of Solid-State Circuits, 2020 This article presents a 390-GHz outphasing transmitter in 28-nm CMOS. Generating higher order modulation schemes at terahertz (THz) frequencies is very challenging due to the essential nonlinear elements needed to generate signals above Fmax.

Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation
Advanced Functional Materials, EarlyView.In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.

Annals of Neurology, EarlyView.Objective The evidence regarding adherence to dietary patterns and Parkinson's disease (PD) risk is inconsistent. Because of the long prodromal PD phase, reverse causation represents a major threat to investigations of diet in relation to PD. We examined whether adherence to the Mediterranean (MED) and Mediterranean‐Dietary Approaches to Stop ...

Rockburst prediction based on data preprocessing and hyperband‐RNN‐DNN
Deep Underground Science and Engineering, EarlyView.A data preprocessing workflow is proposed to address challenges in rockburst data analysis. Coupled algorithms preprocess the data set, and hyperband optimization is used to enhance RNN performance. Results show that preprocessing improves accuracy, while dense layers enhance model stability and prediction performance.
