dynoGP: Deep Gaussian Processes for Dynamic System Identification

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Synergistic 3D π–π networks enforce persistent foldamer configuration with tunable full-color circularly polarized luminescence

Communications Chemistry
Achieving molecular chirality with enantiostability in purely π-conjugated foldamers remains a substantial challenge due to inherently weak π-π stacking interactions and facile racemization.

1-Benzyl-3-methylquinoxalin-2(1H)-one

IUCrData, 2018
The asymmetric unit of the title compound, C16H14N2O, contains three independent molecules differing primarily in the orientations of the benzyl groups. Each independent molecule forms inversion related dimers via offset π-stacking interactions.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
