In Arabidopsis thaliana, multiple genes involved in shoot apical meristem （SAM） transitions have been char- acterized, but the mechanisms required for the dynamic attainment of vegetative, inflorescence, and floral meristem （VM, IM, FM） cell fates during SAM transitions are not well understood. Here we show that a MADS-box gene, XAANTAL2 （XAL2/AGL14）, is necessary and sufficient to induce flowering, and its regula- tion is important in FM maintenance and determinacy, xal2 mutants are late flowering, particularly under short-day （SD） condition, while XAL2 overexpressing plants are early flowering, but their flowers have vege- tative traits. Interestingly, inflorescences of the latter plants have higher expression levels of LFY, AP1, and TFL1 than wild-type plants. In addition we found that XAL2 is able to bind the TFL1 regulatory regions. On the other hand, the basipetal carpels of the 35S：：XAL2 lines lose determinacy and maintain high levels of WUS expression under SD condition. To provide a mechanistic explanation for the complex roles of XAL2 in SAM transitions and the apparently paradoxical phenotypes of XAL2 and other MADS-box （SOCl, AGL24） over- expressors, we conducted dynamic gene regulatory network （GrN） and epigenetic landscape modeling. We uncovered a GrN module that underlies VM, IM, and FM gene configurations and transition patterns in wild- type plants as well as loss and gain of function lines characterized here and previously. Our approach thus provides a novel mechanistic framework for understanding the complex basis of SAM development.

INVESTIGATION OF BONDING IN NANO-SiO_(2) BY Si L_(2,3) X-rAY ABSOrPTION NEAr-EDGE STrUCTUrE SPECTrOSCOPY

Acta Metallurgica Sinica(English Letters) 2001年第6期14卷 473-478页

The Si L2,3 X-ray absorption near-edge structure (XANES) can be used to probe thelocal structure around Si and derive electronic information of the unoccupied s- andd-like partial density of states in nano-size SiO2. We present Si L2,3-edge for threedifferent size silicates acquired by total electron yield (TEY) at the photoemission sta-tion of Beijing Synchrotron radiation Facility (BSrF). The Si L2,3-edge spectra areinterpreted based on ab initio full multiple-scattering (MS) calculation. The Si L2.3-edge of nano-size materials has XANES similar to that of a-quartz. The similaritiesbetween the Si L2.3-edge shapes attest to a common molecular-orbital picture of theirSi-O bonding and the same coordination state. However, a considerable broadeningof Si L2,3-edge XANES spectra as decrease of particle size is also an indicative ofpolyhedral distortions.

We pose and study a scheduling problem for an electric load to develop an Internet of Things(IoT)control system for power appliances,which takes advantage of real-time dynamic energy *** historical pricing data from a large *** supplier,we study and compare several dynamic scheduling policies,which can be implemented in a smart home to activate a major appliance(dishwasher,washing machine,clothes dryer)at an optimal time of the day,to minimize electricity *** formulate our scheduling task as a supervised machine learning classification problem which activates the load during one of two preferred time *** features used in the machine learning problem are hourly market,spot and day-ahead prices along with delayed label of the prior *** find that boosting tree-based algorithms outperform any other classification approach with measurable reduction of energy costs over certain types of naive and static *** observe that the delayed label has most predictive power across features,followed,on average,by spot,hourly market,and day-ahead energy *** further discuss implementation issues using a micro controller system coupled with cloud-based serverless computing and dynamic data *** test system includes an interactive voice interface via an intelligent personal assistant.

Nevirapine induces apoptosis in liver(HepG2) cells

Asian Pacific journal of Tropical Medicine 2016年第6期9卷 531-536页

Objective: To generate insights into the mechanism of NVP induced hepatotoxicity. Methods: Liver(HepG2) cells were cultured with various concentrations of NVP. This cell line was chosen because it has low expression of cytochrome P450, allowing evaluation of the effects of NVP rather than specific metabolites. Cytotoxicity was determined using a proliferation assay and cell numbers were monitored using trypan blue exclusion assay for long term culture experiments and apoptosis induction was determined by morphological and biochemical investigation. results: HepG2 cells treated with the highest concentration of NVP tested(819 μM) initially showed a rounded morphology and all cells had died by week three of exposure. Nuclear condensation and fragmentation, increased Annexin V/propidium iodide staining and caspase 9 activation all supported the induction of apoptosis in HepG2 cells in response to NVP treatment. Conclusions: There is a clear induction of apoptosis in response to NVP which suggests that NVP has significant cytotoxicity, over and above any cytotoxicity of metabolites and may contribute directly to patient hepatotoxicity.

"阿拉伯"卫星的推进剂贮箱是球形、全钛合金的焊接组件,用于存贮燃料甲基肼和氧化剂四氧化二氮的贮箱结构形式一样,每个卫星上使用两个贮箱,装在卫星的标称自旋轴上,一个放在另一个的上面。贮箱内有一个带导向叶片、气泡陷阱和海绵状结构的表面张力推进剂管理装置(PMD),可提供不含气体的推进剂,挤出效率大于99.5%。贮箱设计成可与三种不同的运载工具-Thor/Delta、阿里安、STS兼容。在运载工具Thor/Delta或STS上助推后,PAM-D入轨级在转移轨道点火期间,需要自旋稳定。这以后,所有卫星机动都是在三轴稳定的状态下进行的。推进剂管理装置的主要设计目标是将倾向于增加卫星章动角并最终能产生平旋状态的自旋能耗减到最小程度。推进剂管理装置设计成在所有的自旋稳定机动期间,都能按要求输送不合气体的推进剂,并且在平旋状态下以及对所有轨道机动都能提供不合气体的推进剂。鉴定用的一个贮箱组件经受了广泛的鉴定试验系列,六个装星产品进行了验收试验。未发现任何故障、未经重新设计就顺利通过了所有试验。
