Threshold-Governed Inversion of Plasma Chronology at Air–Silicon Interfaces Under Tight Femtosecond Focusing
Published 2025-06-01“…Through time-resolved shadowgraphy with 550 fs resolution, we demonstrate that silicon plasma precedes air filamentation by approximately 3 ps, a temporal discrepancy that can be quantitatively attributed to the 137.5-fold lower ionization threshold of silicon compared to air. …”

Dimensionality Reduction Reconstitution for Extreme Multistability in Memristor-Based Colpitts System
Published 2019-01-01“…To explore dynamical mechanism, an equivalent 3-D dimensionality reduction model is built using the state variable mapping (SVM) method, which allows the implicit initials of the 4-D memristor-based Colpitts system to be changed into the corresponding explicitly initials-related system parameters of the 3-D dimensionality reduction model. …”

An inevitably ageing world: analysis on the evolutionary pattern of age structure in 200 countries
Published 2025-04-01“…The findings reveal that, while disparities in age demographics are widening, most nations follow remarkably similar evolutionary trajectories, differing mainly in the pace of change. A universal transition from the demographic dividend to population ageing is evident, with even labour-abundant regions such as Africa, Asia and South America inevitably facing this demographic shift. …”

A large elevation in 15N/14N of collagenous amino acids: an insight from starvation experiments of marine organisms
Published 2025-02-01“…We thus demonstrate that the consumption of collagen in organisms under starvation shows a unique elevation pattern in the δ15NAA value, which is consistent with the observation that collagen is degraded non-quantitatively by the collagenase reaction, whereas muscle is degraded quantitatively by the chaperone-mediated autophagy. …”

Numerical Simulation of the Effect of Long-Term Reclamation on the Flow and Sediment Concentration in Binhai Port,Yancheng
Published 2021-01-01“…Binhai Port is located at the most obvious corrosive coastline of the abandoned Yellow River delta in the north of Jiangsu Province,where the near-shore wave and flow dynamic is strong,the sediment movement is relatively active,the underwater terrain is complex and the slope erosion is obvious.Based on the measured hydrological and sediment data and a two-dimensional mathematical model for wave,tidal current and sediment,this paper quantitatively analyzes the influence of the long-term reclamation project on the flow and sediment concentration in the study area and the surrounding estuary,and emphatically discusses the back silting characteristics and deposition causes of the 300 000-ton channel during normal and rough weather.The results show that:After the implementation of the reclamation project,the flow and sediment characteristics of the study area don't change in a large scale,and mainly the flow and sediment near the project site is affected.The sediment is deposited after the channel dredging and a sediment deposit centered at the area with peak sediment concentration is formed in the channel,with decreasing deposition thickness to the port and outer sea channel.During rough weather,the maximum deposition thickness can reach 8~24 times of that in normal weather,but it is less than 0.2 m/d and there is no sudden silting and navigation blocking.…”
