Electrochemical ammonia synthesis via nitrate reduction on Fe single atom catalyst
Nature Communications, 2021 Electrochemically converting nitrate, a widespread water pollutant, back to valuable ammonia is a green and delocalized route for ammonia synthesis, and can be an appealing and supplementary alternative to the Haber-Bosch process.

Proceedings of the 53rd Annual Meeting of the Association for Computational Linguistics and the 7th International Joint Conference on Natural Language Processing (Volume 1: Long Papers), 2015 We reduce phrase-representation parsing to dependency parsing. Our reduction is grounded on a new intermediate representation, "head-ordered dependency trees", shown to be isomorphic to constituent trees. By encoding order information in the dependency labels, we show that any off-the-shelf, trainable dependency parser can be used to produce ...

Disaster Prevention and Rescue Information Service Platforms
International Journal of Automation and Smart Technology, 2011 Because of its special hydrology and physiographic environmental conditions, Taiwan experiences a wide range of natural disasters, such as typhoons, floods, slope collapses, debris flows, and earthquakes, resulting in the loss of many lives and ...

Europe-wide reduction in primary productivity caused by the heat and drought in 2003
Nature, 2005 Future climate warming is expected to enhance plant growth in temperate ecosystems and to increase carbon sequestration. But although severe regional heatwaves may become more frequent in a changing climate, their impact on terrestrial carbon cycling is ...

, 2015 We reduce non-deterministic time $T \ge 2^n$ to a 3SAT instance $ϕ$ of quasilinear size $|ϕ| = T \cdot \log^{O(1)} T$ such that there is an explicit circuit $C$ that on input an index $i$ of $\log |ϕ|$ bits outputs the $i$th clause, and each output bit of $C$ depends on $O(1)$ input bits. The previous best result was $C$ in NC$^1$.

Geoscience Letters, 2022 Heavy rainfall brought by typhoons has been recognised as a major trigger of landslides in Taiwan. On average, 3.75 typhoons strike the island every year, and cause large amounts of shallow landslides and debris flow in mountainous region.
