Research on Chinese Question‐Answering for Gaokao Based on Graph

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Reading comprehension Question‐Answering (QA) for College Entrance Examination (Gaokao in Chinese) is a challenging AI task because it requires effective representation to capture complicated semantic relations between the question and answers. In this paper, a novel method of Chinese Automatic Question‐Answering based on a graph is proposed.

Analysing continuous proportions in ecology and evolution: A practical introduction to beta and Dirichlet regression

open access: yesMethods in Ecology and Evolution, Volume 10, Issue 9, Page 1412-1430, September 2019., 2019
Abstract Proportional data, in which response variables are expressed as percentages or fractions of a whole, are analysed in many subfields of ecology and evolution. The scale‐independence of proportions makes them appropriate to analyse many biological phenomena, but statistical analyses are not straightforward, since proportions can only take values

High‐Performance Sodium‐Ion Capacitors With Kinetics‐Matched Characteristics Enabled by N/O/S‐Doped Homologous Carbon Electrodes Derived From a Single Precursor

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.

Density Functional Theory‐Guided Design and Fabrication of Cu/g‐C3N4 Single‐Atom Catalysts for Efficient Nitrate Reduction to Ammonia

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐
