Hurricane risk assessment in a multi-hazard context for Dominica in the Caribbean
Scientific Reports, 2023 Hurricanes can trigger widespread landslides and flooding creating compound hazards and multiple risks for vulnerable populations. An example is the island of Dominica in the Caribbean, where the population lives predominantly along the coast close to ...

Feature dimensionality reduction: a review
Complex & Intelligent Systems, 2022 As basic research, it has also received increasing attention from people that the “curse of dimensionality” will lead to increase the cost of data storage and computing; it also influences the efficiency and accuracy of dealing with problems.

Active hydrogen boosts electrochemical nitrate reduction to ammonia
Nature Communications, 2022 Electrochemical nitrate reduction to ammonia is a promising alternative strategy to the traditional Haber-Bosch process but suffers from a low Faradaic efficiency and limited ammonia yield due to the sluggish multi-electron/proton-involved steps. Herein,

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.

, 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$^1$.

Marrying the merits of Nagelian reduction and functional reduction [PDF]
, 2011 This paper points out the merit of Nagelian reduction, namely to propose a model of inter-theoretic reduction that retains the scientific quality of the reduced theory, and the merit of functional reduction, namely to take multiple realization into ...
