The working principle of low-temperature adsorption drying and the advantages of its application for biological materials drying were introduced in this paper. By using fresh ginger as the drying material, the effects of temperature and relative humidity on its drying characteristics were examined. The results show that the drying rate increases with the temperature increasing or the humidity decreasing. The drying time to the equilibrium is almost the same under different humidity conditions, but low equilibrium moisture content can be acquired under low humidity. The shrinkage characteristics of fresh ginger were also studied. The change of its surface appearance during the drying process was characterized by the new Charged Coupled Device （CCD） and the Environmental Scanning Electron Microscopy （ESEM） technique. A mathematical model of drying dynamics was set up according to the experiments.

Na-ion O3-type layered oxides are prospective cathodes for Na-ion batteries due to high energy density and ***,such cathodes usually suffer from phase transitions,sluggish kinetics and air instability,making it difficult to achieve high performance solid-state sodium-ion ***,the high-entropy design and Li doping strategy alleviate lattice stress and enhance ionic conductivity,achieving high-rate performance,air stability and electrochemically thermal stability for Na_(0.95)Li_(0.06)Ni_(0.25)Cu_(0.05)Fe_(0.15)Mn_(0.49)O_(2).This cathode delivers a high reversible capacity(141 mAh g^(−1)at 0.2C),excellent rate capability(111 mAh g^(−1)at 8C,85 mAh g^(−1)even at 20C),and long-term stability(over 85%capacity retention after 1000 cycles),which is attributed to a rapid and reversible O3–P3 phase transition in regions of low voltage and suppresses phase ***,the compound remains unchanged over seven days and keeps thermal stability until 279℃.Remarkably,the polymer solid-state sodium battery assembled by this cathode provides a capacity of 92 mAh g^(−1)at 5C and keeps retention of 96%after 400 *** strategy inspires more rational designs and could be applied to a series of O3 cathodes to improve the performance of solid-state Na-ion batteries.

针对先天性心脏病相关肺动脉高压听诊特征不明显,已有的机器辅助诊断算法相对复杂等问题,提出一种基于第二心音信号高频分量统计特征的分析方法。首先,采用端点检测自适应分割方法提取第二心音。其次,使用离散小波变换分解出高频分量,并提取该分量的赫斯特(Hurst)指数、勒佩尔-齐夫(Lempel-Ziv)信息和样本熵等统计特征。最后,使用这些特征训练极端梯度提升算法(XGBoost)分类器,在三分类中准确率达到了80.45%。该方法无需进行降噪处理,特征提取速度快,且只需三个特征即可实现较好的多分类效果,有望用于先天性心脏病相关肺动脉高压早期筛查。
