Two dimensional(2D) layered semiconductors are very promising for post-silicon ultrathin channels and flexible electronics due to the remarkable dimensional and mechanical properties. besides molybdenum disulfide(MoS), the first recognized 2D semiconductor, it is also important to explore the wide spectrum of layered metal chalcogenides(LMCs) family and to identify possible compounds with high performance. Here we report the fabrication of high-performance top-gated field-effect transistors(FETs) and related logic gates from monolayer tin disulfide(SnS), a type of non-transition metal dichalcogenide. The measured carrier mobility of our monolayer devices reaches 50 cm/Vs, largely higher than that of the back-gated counterparts( cm/Vs). based on a direct-coupled FET logic technique, advanced boolean logic gates and operations are also implemented, with the voltage gain of 3.5 and output swing of >90% for the NOT and NOR gates, respectively. The superior electrical and integration properties make monolayer SnS a strong candidate for next-generation atomic electronics.

10个片麻岩和花岗岩的磷灰石裂变径迹年龄值位于 3 5 .6～ 13 .6Ma之间 ,表明了阿尔金山脉的隆升开始于渐新世 ,并一直延续至中新世。山脉早期的隆升速率较低 ,后期可能存在一个快速的隆升时期 ;阿尔金山脉并非整体的均匀隆升 ,其内分布的NEE走向的断裂也局部控制了山体的隆升 ;如果山脉的隆升是阿尔金断裂左行走滑的结果 ,那么可推测阿尔金断裂大型左行走滑的起始时间应为渐新世。区域资料分析表明 ,青藏高原北缘在渐新世至中新世期间发生了大规模的、区域性的抬升。

Tubal Infertility and Chlamydia Trachomatis in a Congolese Infertile Population

引用

Open j.urnal of Obstetrics and Gynecology 2016年第1期6卷 40-49页

Infertility of tubal origin is the most frequent in sub-Saharan area. It is due to tuboperitoneal lesions mainly because of infection;especially sexually transmitted infection. Worldwide, Chlamydia trachomatis is the main pathogen. In our setting, some studies failed to establish the link between tubal infertility and chlamydia trachomatis. The current study aimed to determine the local data related to chlamydia trachomatis role in tubal infertility and the usefulness of Chlamydia trachomatis antibody titer test (CAT) in discrimination of the patients with and without tuboperitoneal lesions. Patients’ average age was 33.9 ± 4.8 years, average coitarche 19.4 ± 4.4 years and average number of partners: 3.1 ± 1.6. The level of CAT is correlated to the tuboperitoneal severity. CAT was more specific (93.3%;CI 95%: 81.7 - 98.6) than sensitive (72.7% CI 95%: 49.8 - 89.3) and discriminated correctly 89% (AUC = 0.89) of the patients with or without tuboperitoneal lesions. In conclusion, as it is stated worldwide, Chlamydia trachomatis is the most frequent sexually transmitted pathogen associated with tubal infertility. CAT has to be used as a tool to select patients to be submitted to invasive investigation, like laparoscopy.
