Agricultural practices significantly contribute to greenhouse gas(GHG)emissions,necessitating cleaner production technologies to reduce environmental pressure and achieve sustainable maize *** film mulching is commonly used in the Loess Plateau *** slow-release fertilizers as a replacement for urea within this practice can reduce nitrogen losses and enhance crop *** these techniques represents a novel agricultural approach in semi-arid ***,the impact of this integration on soil carbon storage(SOCS),carbon footprint(CF),and economic benefits has received limited research ***,we conducted an eight-year study(2015-2022)in the semi-arid northwestern region to quantify the effects of four treatments[urea supplied without plastic film mulching(CK-U),slow-release fertilizer supplied without plastic film mulching(CK-S),urea supplied with plastic film mulching(PM-U),and slow-release fertilizer supplied with plastic film mulching(PM-S)]on soil fertility,economic and environmental *** results revealed that nitrogen fertilizer was the primary contributor to total GHG emissions(≥71.97%).Compared to other treatments,PM-S increased average grain yield by 12.01%-37.89%,water use efficiency by 9.19%-23.33%,nitrogen accumulation by 27.07%-66.19%,and net return by 6.21%-29.57%.Furthermore,PM-S decreased CF by 12.87%-44.31%and CF per net return by 14.25%-41.16%.After eight years,PM-S increased SOCS(0-40 cm)by 2.46%,while PM-U decreased it by 7.09%.These findings highlight the positive effects of PM-S on surface soil fertility,economic gains,and environmental benefits in spring maize production on the Loess Plateau,underscoring its potential for widespread adoption and application.

HfO2-based ferroelectric field-effect transistor（Fe FET） has become a promising solution for next-generation embedded non-volatile memory（NVM） owing to its complementary metal-oxide-semiconductor（CMOS） compatibility,small footprint, high performance, and non-destructive readout [1]. Recent research of HfO2-based Fe FET has focused on the device operation mechanisms as well as reliability issues such as the interplay between polarization switching and charge trapping/detrapping [2], read-after-write latency [3] and endurance degradation [4].

Science China Chemistry 2018年第9期61卷 1088-1098页

作者： miaomiao zhang Gaolin Liang Hefei National Laboratory of Physical Sciences at Microscale Department of Chemistry University of Science and Technology of China

Herein, we review the development, applications and potential prospects of CBT-Cys click reaction. This click condensation reaction is based on the condensation reaction between 2-cyanobenzothiazole(CBT) and D-cysteine(D-Cys) in fireflies and has high biocompatibility and controllability in physiological solutions. Under the control of p H, reduction, or enzyme, this CBTbased click reaction has been widely applied to a wide range of biomedical fields such as protein labeling, molecular imaging(e.g., optical imaging, nuclear imaging, magnetic resonance imaging and photoacoustic imaging), nanomaterial fabrication, cancer therapy, and other potentialities.

Learning real-time automata

引用

Science China(Information Sciences) 2021年第9期64卷 57-73页

作者： Jie AN Lingtai WANG Bohua ZHAN Naijun ZHAN miaomiao zhang School of Software Engineering Tongji University State Key Laboratory of Computer Science Institute of Software Chinese Academy of Sciences University of Chinese Academy of Sciences

Real-time automata(RTAs) are a subclass of timed automata with only one clock which resets at each transition. In this paper, we present an active learning algorithm for deterministic real-time automata(DRTAs) in both continuous-time semantics and discrete-time semantics. For a target language recognized by a DRTA A, we convert the problem of learning DRTA A to the problem of learning a canonical real-time automaton A with the same recognized language, i.e., L(A) = L(A). The algorithm is inspired by existing learning algorithms for symbolic automata.
