Soil nitrate mediates the responses of plant community production to the frequency of N addition in a temperate grassland: a decadal field experiment
Nitrogen (N) enrichment through either artificial N application or atmospheric N deposition often increases ecosystem aboveground net primary productivity (ANPP). Therefore, results from N addition experiments...

New algorithms for verifiable outsourcing of bilinear pairings
双线性对运算是密码学中最昂贵的运算之一, 已有的对运算外包计算方案效率很低或可验证概率不高。 基于两个不可信的服务器, 我们提出了新的双线性对运算外包方案。 用户不需要执行任何复杂度高的运算, 如标量乘、 模乘运算等。 如果服务器返回错误的计算结果, 用户能以概率 1 检测到, 即外包结果能完全验证。 与已有方案相比, 所提方案能同时提高双线性对运算的计算效率和可验证概率。
