As battery deployments in electric vehicles and energy storage systems grow, ensuring homogeneous performance across units is crucial. We propose a multi-derivative imaging fusion(MDIF) model, employing advanced imaging and machine learning to predict battery aging trajectories from minimal initial data, thus facilitating effective performance grouping before deployment. Utilizing a derivative strategy and Gramian Angular Difference Field for dimensional enhancement, the MDIF model uncovers subtle predictive features from discharge curve data after only ten cycles. The architecture includes a parallel convolutional neural network with lateral connections to enhance feature integration and *** on a self-developed dataset, the model achieves an average root-mean-square error of 0.047 Ah and an average mean absolute percentage error of 1.60%, demonstrating high precision and *** robustness is further validated through transfer learning on two publicly available datasets, adapting with minimal retraining. This approach significantly reduces the testing cycles required, lowering both time and costs associated with battery testing. By enabling precise battery behavior predictions with limited data, the MDIF model optimizes battery utilization and deployment strategies, enhancing system efficiency and sustainability.

＜正＞Objective: To observe the effect of EGFR activation on KCNQ2/3 potassium channel and explore the mechanism of regulation. Methods: The KCNQ2 and KCNQ3 potassium channel were co- expressed in HEK293 cell using Lipofectamine kits （Invitrogen）. Whole-cell patch clamp recordings were made from HEK293 cell. The laser confocal microscopy technique was used to monitor the changes of membrane PIP2, PIP3 and intracellular Ca2+. Results: （1）KCNQ2/3 currents were inhibited by long incubation with EGF in HEK293 cells. HEK293 cells expressing KCNQ2/3 channels were pre-incubated with EGF（100ng/ml） for 30 min. The KCNQ2/3 currents elicited from these cells were inhibited significantly;the amplitude of the currents was decreased to 28%±9.2% （n=5, P＜0.01）;the half activation voltage was shifted from （-16.6±1.2）mV to （-13.5±1.5）mV;the activation and deactivation kinetic processes were slowed. （2）A tyrosine phosphatase inhibitor vanadate （100μmol/l） mimicked EGF actions and decreased the KCNQ2/3 current to 45%±12.8% （n=5, P＜0.01）;the time constant of activation and deactivation were prolonged from （230±37）ms, （130±28）ms to （535±42）ms, （358±39）ms, respectively.

New seismic imaging from the Mussau Trench confirms that, under horizontal compression on an oceanic plate boundary, it is within the young and weak oceanic plate that a trench will develop, and it is the young plate, not so long after its birth, that starts to subduct toward the old plate. The Mesozoic Pacific Plate cannot easily bend, under the joint horizontal compression and vertical gravity pull, even with a pre-existing weak zone in place and with a large age offset across the plate boundary. The bending of the Caroline Plate near the northern end of the Mussau Trench started only after a long-time span of trench migration, and/or after a prolonged transition from initial compression to trench development. Highly contrasting trench deformation and sedimentary accretion between two parallel seismic sections support an evident migration of underthrusting or significant longitudinal heterogeneity along the trench. The swift transition from underthrusting to non-thrusting can be explained by a counter-clockwise rotation of the Caroline Plate. That miniature accretionary wedges develop even before the subduction initiates imply strong compression and uplifting before the underthrusting can kick-start. Rotation of the Caroline Plate have been halted as the Mussau Trench is seismically rather quiet and the Lyra Trough to the east shows relaxational extension.
