Molecular electronics represent the cutting-edge and interdisciplinary effort on the future miniaturization of electronic circuits. Benefiting from synthetic chemistry and theoretical insights, molecular circuit studies have promoted devices with increasingly complicated structures. Especially, the evolution of conductive backbones from simple chain-shape single-channel configurations to complex multi-channel architectures marks a pivotal progression. A comprehensive understanding of charge transport and conductance properties in multi-channel molecular devices is crucial for further developing molecular circuits. In this review, we provide an overview of conductance properties, categorizing the influence on conductance as either enhancement or suppression. The underlying mechanisms of conductance modulation are discussed as conductance enhancement attributed to factors of the quantum-interference-based superposition law, the charge-induced self-gating effect, and the facilitation of additional conductive channels through through-space transport; while the conductance suppression originates from the destructive quantum interference in saturated conductive channels and the "electron selective transport" feature within multi-channel structure exhibiting the channels converging on a phenyl group.

Dynamic brain networks (DBNs) can capture the intricate connections and temporal evolution among brain regions, becoming increasingly crucial in the diagnosis of neurological disorders. However, most existing researches tend to focus on isolated brain network sequence segmented by sliding windows, and they are difficult to effectively uncover the higher-order spatio-temporal topological pattern in DBNs. Meantime, it remains a challenge to utilize the structure connectivity prior in the DBNs analysis.

Complex experimental protocols often require multi-modal data acquisition with precisely aligned timing, as well as state- and behavior-dependent interventions. Tailored solutions are mostly restricted to individual experimental setups and lack flexibility and interoperability. We present an open-source, Linux-based integrated software solution, called 'Syntalos', for simultaneous acquisition and synchronization of data from an arbitrary number of sources, including multi-channel electrophysiological recordings and different live imaging devices, as well as closed-loop, real-time interventions with different actuators.
