| 1 | Enhancement of femtosecond laser-induced surface ablation via temporal overlapping double-pulse irradiation显示文摘This paper reports the physical phenomenon of the temporal overlapping double femtosecond laser-induced ablation enhancement at different time delays.Detailed thermodynamic modeling demonstrates the ablation enhancement is highly dependent on the first pulse's laser fluence.In the case of the first pulse laser fluence being higher than material's ablation threshold,the ablation enhancement is attributed to optical absorption modification by the first pulse ablation.While the first pulse's laser fluence is lower than the material's ablation threshold,the first pulse-induced melting leads to much higher absorption of the second pulse.However,for the case of the first pulse's laser fluence even lower than melting threshold,the ablation enhancement decreases obviously with time delay.The results of the temporal overlapping double femtosecond laser ablation of poly(ε-caprolactone)are in good agreement with the theoretical predictions. | ZHENYUAN LIN LINGFEI JI MINGHUI HONG | 2020 | Photonics Research2020，8，3： | 5 |

| 4 | mTORC1 signaling pathway regulates tooth repair显示文摘Tooth germ injury can lead to abnormal tooth development and even tooth loss,affecting various aspects of the stomatognathic system including form,function,and appearance.However,the research about tooth germ injury model on cellular and molecule mechanism of tooth germ repair is still very limited.Therefore,it is of great importance for the prevention and treatment of tooth germ injury to study the important mechanism of tooth germ repair by a tooth germ injury model.Here,we constructed a Tg(dlx2b:Dendra2-NTR)transgenic line that labeled tooth germ specifically.Taking advantage of the NTR/Mtz system,the dlx2b+tooth germ cells were depleted by Mtz effectively.The process of tooth germ repair was evaluated by antibody staining,in situ hybridization,Ed U staining and alizarin red staining.The severely injured tooth germ was repaired in several days after Mtz treatment was stopped.In the early stage of tooth germ repair,the expression of phosphorylated 4E-BP1 was increased,indicating that mTORC1 is activated.Inhibition of mTORC1 signaling in vitro or knockdown of mTORC1 signaling in vivo could inhibit the repair of injured tooth germ.Normally,mouse incisors were repaired after damage,but inhibition/promotion of mTORC1 signaling inhibited/promoted this repair progress.Overall,we are the first to construct a stable and repeatable repair model of severe tooth germ injury,and our results reveal that mTORC1 signaling plays a crucial role during tooth germ repair,providing a potential target for clinical treatment of tooth germ injury. | Honghong Liu Yu Yue Zhiyun Xu Li Guo Chuan Wu Da Zhang Lingfei Luo Wenming Huang Hong Chen Deqin Yang | 2023 | International Journal of Oral Science2023，15，1： | 0 |
| 5 | Development of Digital Multi-function Dendrometer显示文摘Multi-functional dendrometer is a kind of forestry tool that can measure multiple factors of forest.By combining sensor technology and computer technology,a digital multi-function dendrometer has been developed,which integrated the functions of measuring height,distance,azimuth, slope,elevation,form quotient of any parts of the stem into one body at the same test.The dendrometer can fit the complex forest environment,solve the difficult problems in aspects of plant height,measure distance,central diameter and form quotient of breast height.The accuracy can meet the requirements of general forest survey. | Liu Falin Zeng Siqi Yan Qianfei Wang Long Hong Lingfei | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
