Slippery liquid-infused porous surfaces (SLIPS) have attracted wide attention in the field of marine anticorrosion. However, the stability problem severely restricts the broad applications of SLIPS. Herein, wefabricated a polyurethane-based ultraslippery surface with lubricant self-replenishing and matrix selfhealingproperties owing to the huge amount of dynamic hydrogen-bond. Besides, the bacteria culturetest and electrochemical analysis results indicate the prepared surface possesses superior properties inthe protection of microbiologically influenced corrosion (MIC). This paper offers an efficient strategy tosolve stability problem of SLIPS, and the as-obtained self-healable ultraslippery surface can be used asa promising material in mitigating MIC.

To investigate the accumulation patterns of Cd and/or Pb in various body parts, organs and tissues of the Asian gypsy moth (Lymantria dispar) larvae under Cd and/or Pb stress, Cd and Pb treated artificial diets were used to feed the larvae in the current study. These larval body parts/organs/tissues included the heads, integuments (body walls), alimentary canals, fat bodies and hemolymphs. Our results showed that under Cd and/or Pb stress, their accumulations in larval body parts/organs/tissues were significantly higher than those in the control, with the amounts of tested metals in the fat bodies and hemolymphs and alimentary canals being significantly higher than those in the heads and integuments. Under the single Cd (0, 7.5, 10.5 mg/kg) or Pb stress (0, 55, 90, 125 mg/kg), the accumulations of these heavy metals were positively correlated with their concentrations in diets. Under the combined stress (Cd × Pb), the Cd accumulation at the lower Pb concentrations was higher than that at higher Pb concentrations for the body parts/organs/tissues, similar effects of Cd concentrations on Pb accumulations were also recorded. These results clearly showed that Cd and/or Pb were accumulated in various body parts/organs/tissues at different levels under the heavy metal stress. And accumulations of Pb/Cd were positively correlated with their concentrations in the diets under the single stress. Under the combined stresses, Cd and Pb had synergistic effects at low concentrations whereas antagonistic effects at high concentrations. The accumulations of Cd and/or Pb in the gypsy moth larvae affects normal physiological and biochemical functions, and thus affects their growth and development.

SEL-RefineMask: A Seal Segmentation and Recognition Neural Network with SEL-FPN
Ze-dong Dun,Jian-yu Chen,Mei-xia Qu,Bin Jiang 한국정보처리학회 2022 Journal of information processing systems Vol.18 No.3
Digging historical and cultural information from seals in ancient books is of great significance. However,ancient Chinese seal samples are scarce and carving methods are diverse, and traditional digital imageprocessing methods based on greyscale have difficulty achieving superior segmentation and recognitionperformance. Recently, some deep learning algorithms have been proposed to address this problem; however,current neural networks are difficult to train owing to the lack of datasets. To solve the afore-mentionedproblems, we proposed an SEL-RefineMask which combines selector of feature pyramid network (SEL-FPN)with RefineMask to segment and recognize seals. We designed an SEL-FPN to intelligently select a specificlayer which represents different scales in the FPN and reduces the number of anchor frames. We performedexperiments on some instance segmentation networks as the baseline method, and the top-1 segmentation result of 64.93% is 5.73% higher than that of humans. The top-1 result of the SEL-RefineMask network reached67.96% which surpassed the baseline results. After segmentation, a vision transformer was used to recognizethe segmentation output, and the accuracy reached 91%. Furthermore, a dataset of seals in ancient Chinesebooks (SACB) for segmentation and small seal font (SSF) for recognition were established which are publiclyavailable on the website.

Effects of Cavity Size and Density on Polymer Micro Hot Embossing
Xiang Zhang,Ge Fang,Tengjiao Jiang,Na Zhao,Junfeng Li,Bowen Dun,Qian Li 한국정밀공학회 2015 International Journal of Precision Engineering and Vol. No.
We designed nine micro molds with various cavity geometric parameters to investigate their effects on micropillars replication of the amorphous polymer via micro hot embossing. Picoseconds laser was used to fabricate the micro holes array on the stainless steel plates with 200 μm thickness as micro molds. The mechanical behavior of PMMA above glass transition temperature was investigated by uniaxial compression tests at various temperatures and strain rates, the results were used in simulation as constitutive relation. Confocal microscope and optical microscope showed that the replication height has a complicate nonlinear relationship with cavity size and density. DEFORM 3D was used to model and simulate the embossing process, and it is a good approach to investigate the micropallars replication heights, front angles and filling ratios.
