Abstract Understanding the dynamics and underlying mechanism of carbon exchange between terrestrial ecosystems atmosphere is one key issues in global change research. In this study, we quantified fluxes different China, analyzed their spatial variation environmental drivers based on long‐term observation data China FLUX sites published from other flux China. The results indicate that gross ecosystem productivity ( GEP ), respiration ER net NEP ) showed a significantly latitudinal pattern,...
Abstract The recent increase in infectious disease outbreaks has been directly linked to the global loss of biodiversity and decline some endangered species populations. Between December 2014 March 2015, five captive giant pandas died due canine distemper virus (CDV) infection China. CDV taken a heavy toll on tigers lions years. Here, we describe first gut microbiome diversity study CDV-infected pandas. By investigating influence bacterial communities infected uninfected individuals...
Porcine reproductive and respiratory syndrome virus (PRRSV) is known to cause disorders, such as abortion, in pregnant sows well immunosuppressive complications, leading severe tract infections young pigs. In this study, an in-depth analysis of the miRNomes mock- virus-infected pig lungs was carried out. We found that highly expressed ssc-miR-30d-R_1 decreased infected lungs, reduced levels were significantly correlated with infection by PRRSV. Moreover, shown target Toll-like receptor 4...
The soil organic carbon pool is the largest and most active part of terrestrial ecosystem pool, plays an important role in global cycle climate change. arid region northwest China located hinterland Eurasia, with extremely fragile ecosystems sensitive responses to It a hot area that many scholars have paid attention recent years, estimation spatial distribution characteristics storage increasingly become one research focuses this region. However, insufficient data sharing relative lack...
Several post-translational modifications in host cells are hijacked by pathogens to facilitate their propagation. A number of components the influenza virus have been reported be modified small ubiquitin-like modifier (SUMO) proteins during infection. We hypothesized that MAPK/ERK pathway could SUMO1 because SUMOylation MEK1 was quickly eliminated after identified cell as a target through LC/MS/MS, and enhanced inhibited infection virus, while inhibition facilitated Further investigation...
Influenza A viruses (IAVs) take advantage of the host acetylation system for their own benefit. Whether nucleoprotein (NP) IAVs undergoes and interaction between NP class I histone deacetylases (HDACs) were largely unknown. Here, we showed that protein IAV interacted with HDAC1, which downregulated level NP. Using mass spectrometry, identified lysine 103 as an site Compared wild-type protein, two K103 mutants, K103A K103R, enhanced replication efficiency recombinant in vitro. We further...
Here, we announce the complete genome sequence of a spontaneous mutant peste des petits ruminants virus (PPRV), termed China/BJ/2014, suggesting that PPRV continues to evolve. This information is crucial for developing strategies efficient prevention and control PPRV.
For many Operating Systems and device drivers, memory copy is the most time-consuming operation which has always been paid special attention. In this paper, we propose a processor DMA based hardware accelerator with goal to reduce instructions executed on CPU, exploit parallelism between computing data transfer in copy. This accomplished by taking advantage of proposed Direct Memory Access (DMA) engine overcomes conventional shortcomings. Experimental results show that solution achieves...
As network speed continues to grow, new challenges of processing are emerging. In this paper, we first study the overheads and interactions among different steps networking from a hardware perspective point out that I/O related memory have become main bottlenecks performance promotion. Then based on analysis, show conventional optimizing solutions insufficient due architecture limitations. Motivated by studies, propose an improved Direct Cache Access (DCA) scheme combined with Integrated NIC...
A 64-bit RISC processor is designed for large applications that need memory address. Due to the restriction of instruction fixed length, loading a address needs number instructions, leading penalty both performance and consumption. This paper describes an computation method based on hardware software co-design. In our extended MIPS which supports register + addressing, we achieve approximate effect access as their 32-bit counterparts, propose load-address method, simplifies calculation We...
The potential evapotranspiration represents the atmospheric evaporation capacity, which is an important indicator to measure regional and also a key parameter evaluate drought degree, balance between supply demand of water resources, consumption vegetation. Based on meteorological data collected by 12 ecological field stations Central Asia Ecosystem Monitoring Network 11 China Research in arid region Northwest China, using Penman-Monteith method recommended FAO, was calculated from 2005...
For the actual demand for carbon cycle research in China, from 2012 to 2013, we started and development on IPv6-based Chinese terrestrial ecosystem flux network. We set up IPv6 sensor network based real-time observation system ten field stations. complete data acquisition, transmission, storage sharing tower station, then center. Researchers develop a series of scientific applications
Since multi-core processor and System-On-Chip (SOC) have developed fast in recent years, the interconnection bus becomes a key factor to system performance. Recently, it is reported that for most desktop embedded systems, bandwidth has not been fully exploited, data transfer efficiency low. In this paper, we show frequent cross-domain transaction main bottleneck of I/O performance promotion. Then based on Hyper Transport (HT) 3.0 controller design, propose an optimization scheme which...
The China FLUX is an observation and research network that provides long-term continuous measurements of the exchanges carbon dioxide, water vapor energy between terrestrial ecosystem atmosphere in China. meteorological ecological data was collected by sensor devices field stations, transmitted to CERN server through internet. To ensure integrity collection transmission, we deployed a Web GIS-based monitor system check visualize status network. It simple distributed application. Currently,...
With the dramatic increase in network speed during past ten years, processing efficiency has been significantly decreased. In this paper, we propose a accelerating scheme, which employs cache locking method to reduce data and instruction accessing latency. Interrupts handling buffer maintenance overheads are obviously Experimental results show that our solution increases about 22% bandwidth reduces 10%
The fast development of mobile devices and commercial electronics brings new challenges to embedded system designers. Meanwhile, on-chip memory in modern systems still not fulfills the needs applications. In this paper, firstly we review two typical models - cache scratch pad show their disadvantages. Then propose an improved model called address-locking cache, which supports innovative locking mechanism with high efficiency. It provides flexibility different applications overcomes...
