研究了Ti掺杂对磁控溅射类金刚石(DLC)薄膜附着力及硬度的影响,同时在Ti掺杂类金刚石(Ti-DLC)薄膜的基础上,通过引入Ti应力缓和层制备了Ti/Ti-DLC/Ti/Ti-DLC……软硬交替多层薄膜,研究了Ti应力缓和层对进一步提高薄膜附着力特性的作用。采用纳米划痕仪和显微硬度计分析测试了薄膜的附着力和硬度。研究表明,金属Ti的掺杂有利于DLC薄膜附着力特性的改善,但对硬度有一定的影响。Ti应力缓和层的导入进一步改善了Ti-DLC薄膜的附着力特性,使其达到或超过了TiN薄膜的水平,对于附着力的改善Ti应力缓和层存在最佳的厚度值。采用特殊的变周期多层结构设计即在应力集中的膜基界面附近采用较小的调制周期,薄膜顶层附近采用较大的调制周期不但可以保持足够的附着力,还可维持Ti-DLC薄膜原有的硬度。

采用电弧离子镀技术在不锈钢SUS440C基片上沉积了CrSiN薄膜,并在此基础上通过引入Cr应力缓和层制备了CrSiN/Cr多层薄膜,研究了Cr应力缓和层对缓解CrSiN薄膜内部应力、增强膜基结合力、提高薄膜沉积厚度的作用。利用X射线衍射仪及sin2ψ法测试计算了薄膜的内部应力、采用扫描电镜及透射电镜观察了薄膜的显微结构,采用微米划痕仪测试了膜基结合强度。结果表明:20～30 nm极薄Cr层的导入,缓解了CrSiN薄膜内部应力的积累,降低了薄膜整体的内部应力,选择合适的Cr层数,最大可降低内部应力1/2。CrSiN/Cr多层膜仍保持了原有的连续柱状晶生长模式,CrSiN层与Cr层间,界面完整清晰,Si-N非晶部分缓解了CrSiN中CrN晶格与Cr层中Cr晶格间的失配,使得层间结合紧密牢固。划痕仪测试结果表明膜基结合强度与薄膜内部应力呈现出高度的相关性,Cr应力缓和层的导入改善了薄膜的膜基结合力、提高了薄膜可沉积厚度。

We applied adaptive dynamics to double slit interference phenomenon using particle model and obtained partial successful results in our previous report. The patterns qualitatively corresponded well with experiments. Several properties such as concave single slit pattern and large influence of slight displacement of the emission position were different from the experimental results. In this study we tried other slit conditions and obtained consistent patterns with experiments. We do not claim that the adaptive dynamics is the principle of quantum mechanics, but the present results support the probability of adaptive dynamics as the candidate of the basis of quantum mechanics. We discuss the advantages of the adaptive dynamical view for foundations of quantum mechanics.

The immune-stromal cell interactions play a key role in health and diseases. In periodontitis, the most prevalent infectious disease in humans, immune cells accumulate in the oral mucosa and promote bone destruction by inducing receptor activator of nuclear factor-κB ligand (RANKL) expression in osteogenic cells such as osteoblasts and periodontal ligament cells. However, the detailed mechanism underlying immune–bone cell interactions in periodontitis is not fully understood. Here, we performed single-cell RNAsequencing analysis on mouse periodontal lesions and showed that neutrophil–osteogenic cell crosstalk is involved in periodontitis-induced bone loss. The periodontal lesions displayed marked infiltration of neutrophils, and in silico analyses suggested that the neutrophils interacted with osteogenic cells through cytokine production. Among the cytokines expressed in the periodontal neutrophils, oncostatin M (OSM) potently induced RANKL expression in the primary osteoblasts, and deletion of the OSM receptor in osteogenic cells significantly ameliorated periodontitis-induced bone loss. Epigenomic data analyses identified the OSM-regulated RANKL enhancer region in osteogenic cells, and mice lacking this enhancer showed decreased periodontal bone loss while maintaining physiological bone metabolism. These findings shed light on the role of neutrophils in bone regulation during bacterial infection, highlighting the novel mechanism underlying osteoimmune crosstalk.

Triassic-Jurassic carbonates widely distributed in Eastern Indonesia are believed as oils source rock. The Mesozoic Tokala Formation exhibit source rock potential, as evidenced by high contents of organic matter. Recent exploration has been conducted in southeastern Sulawesi, targeting the Mesozoic intervals. Therefore, in this study, we attempted to determine source rock potential of Tokala Formation outcropped in southeastern Sulawesi area and its capability to generate hydrocarbon. Five distinct lithofacies were delineated, emphasizing lithological and mineralogical features: foraminifera wackestone (FW), lime mudstone (LM), massive bioturbated calcareous-argillaceous shale (MBCAS), weakly laminated argillaceous-calcareous shale (WLACS), and strongly laminated calcareous-argillaceous shale (SLCAS). Subsequent analyses showed that carbonate-rich samples (FW and LM facies, >50% CaO) had poor source rock potential. Conversely, shale facies with moderate carbonate content (WLACS, MBCAS, and SLCAS, 15% - 50% CaO) had good to excellent source rock characteristics, qualifying them as preferable source rock. In addition, levels of SiO2 and Al2O3 should not be neglected, as these constituents play important roles in clay mineral adsorption. Laminated shale facies with moderate CaO content tended to be more promising as source rock than bioturbated facies. The shale facies of Tokala Formation indicate prospective source rock horizon.

AIMTo elucidate the effect of antithrombotic therapy （ATT） on bleeding and thromboembolic complications during or after laparoscopic digestive *** articles or internationally accepted abstracts between 2000 and 2017 were searched from PubMed, Cochrane Database, and Google Scholar, and studies involving laparoscopic digestive surgery and antiplatelet therapy （APT） and/or anticoagulation therapy （ACT） were included after careful review of each study. Data such as study design, type of surgical procedures, antithrombotic drugs used, and surgical outcome （both bleeding and thromboembolic complications） were extracted from each *** published articles and two internationally accepted abstracts were eligible for inclusion in the systematic review. Only one study concerning elective laparoscopic cholecystectomy in patients with peri-operative heparin bridging for ACT showed that the risk of postoperative bleeding was higher compared with those without ACT. The remaining 14 studies reported no signifcant differences in the incidence of bleeding complications between the ATT group and the group without ATT. The risk of thromboembolic events （TE） associated with laparoscopic digestive surgery in patients receiving ATT was not signifcantly higher than those with no ATT or interrupted *** T et al . Laparoscopic digestive surgery and antithrombotic therapyCONCLUSIONLaparoscopic digestive surgery in ATT-burdened patients for prevention of bleeding and TE showed satisfactory results. The risk of hemorrhagic complication during or after these procedures in patients with continued APT or heparin bridging was not signifcantly higher than in patients with no ATT or interrupted APT.
