| 2 | Seasonal Rainfall Forecasts for the Yangtze River Basin of China in Summer 2019 from an Improved Climate Service显示文摘Rainfall forecasts for the summer monsoon season in the Yangtze River basin(YRB) allow decision-makers to plan for possible flooding, which can affect the lives and livelihoods of millions of people. A trial climate service was developed in 2016, producing a prototype seasonal forecast product for use by stakeholders in the region, based on rainfall forecasts directly from a dynamical model. Here, we describe an improved service based on a simple statistical downscaling approach. Through using dynamical forecast of an East Asian summer monsoon(EASM) index, seasonal mean rainfall for the upper and middle/lower reaches of YRB can be forecast separately by use of the statistical downscaling, with significant skills for lead times of up to at least three months. The skill in different sub-basin regions of YRB varies with the target season. The rainfall forecast skill in the middle/lower reaches of YRB is significant in May–June–July(MJJ), and the forecast skill for rainfall in the upper reaches of YRB is significant in June–July–August(JJA). The mean rainfall for the basin as a whole can be skillfully forecast in both MJJ and JJA. The forecasts issued in 2019 gave good guidance for the enhanced rainfall in the MJJ period and the near-average conditions in JJA. Initial feedback from users in the basin suggests that the improved forecasts better meet their needs and will enable more robust decision-making. | Philip E.BETT Nicola MARTIN Adam A.SCAIFE Nick DUNSTONE Gill M.MARTIN Nicola GOLDING Joanne CAMP Peiqun ZHANG Chris D.HEWITT Leon HERMANSON Chaofan LI Hong-Li REN Ying LIU Min LIU | 2020 | Journal of Meteorological Research2020，34，5： | 7 |
| 3 | Seasonal Forecasts of the Summer 2016 Yangtze River Basin Rainfall显示文摘The Yangtze River has been subject to heavy flooding throughout history,and in recent times severe floods such as those in 1998 have resulted in heavy loss of life and livelihoods.Dams along the river help to manage flood waters,and are important sources of electricity for the region.Being able to forecast high-impact events at long lead times therefore has enormous potential benefit.Recent improvements in seasonal forecasting mean that dynamical climate models can start to be used directly for operational services.The teleconnection from El Ni ?no to Yangtze River basin rainfall meant that the strong El Ni ?no in winter 2015/16 provided a valuable opportunity to test the application of a dynamical forecast system.This paper therefore presents a case study of a real-time seasonal forecast for the Yangtze River basin,building on previous work demonstrating the retrospective skill of such a forecast.A simple forecasting methodology is presented,in which the forecast probabilities are derived from the historical relationship between hindcast and observations.Its performance for2016 is discussed.The heavy rainfall in the May–June–July period was correctly forecast well in advance.August saw anomalously low rainfall,and the forecasts for the June–July–August period correctly showed closer to average levels.The forecasts contributed to the confidence of decision-makers across the Yangtze River basin.Trials of climate services such as this help to promote appropriate use of seasonal forecasts,and highlight areas for future improvements. | Philip E.

| 4 | Micro/nano-mechanical behaviors of individual FCC,BCC and FCC/BCC interphase in a high-entropy alloy显示文摘Here,a systematic investigation was made on the interphase strengthening effects induced superior me-chanical performances of multiphase high-entropy alloys(HEAs)at micro/nano-scale,compared with sin-gle phase HEAs.A pillar compression test under a scanning electron microscope(SEM)was performed on the individual face centered cubic(FCC),body centered cubic(BCC),and mixed-phases with different di-ameters in a Fe_(24)Co_(25)Ni_(24)Cr_(23)Al_(4)HEA using focused ion beam(FIB)milling and a nanoindenter equipped with a flat punch.The stress-strain response of pillar underneath the indenter was selected to explore the diameter/phase-dependent size effect,the periodically fluctuation of local stress,and strain hardening.It was revealed that the pillars at the interphase exhibited significantly higher strength,compared with the FCC and BCC pillars.An experiment also verified the coincident mechanical size effects independent with the type of phases.The stress responses in the mixed-phase pillars manifested as a distinct transition from the dramatic drop to the minor fluctuation during the post-yield stages with the increasing strain,indicating the propagation of Al-Ni enriched solid solution phase(BCC1)under compression.Except the BCC1 phase,numerous dislocations were observed in the post-deformed pillars,particularly serving as the major source to enhance the strain hardening of BCC pillars. | Wei Zhang Zhichao Ma Chaofan Li Chaowei Guo Dongni Liu Hongwei Zhao Luquan Ren | 2022 | Journal of Materials Science & Technology2022，，19： | 1 |
| 5 | Early specializations for mimicry and defense in a Jurassic stick insect显示文摘Mimicry and secondary defense are staples among predator–prey interactions.Among insects,the stick and leaf insects are masters of camouflage.Nonetheless,a meager understanding of their origin and early mimetic evolution persists.Here,we report the earliest mimetic and defensive strategies of a stick insect from the Middle Jurassic of China,Aclistophasma echinulatum gen.et sp.nov.,exquisitely preserving abdominal extensions and femoral spines.The distribution of these characteristics mapped onto the phylogeny of Phasmatodea reveals that abdominal extensions and femoral spines developed multiple times during the evolution of stick insects,and indicates that the origin of abdominal extensions predates other modifications,while tergal extensions predate other expansions of the body,such as those of the sterna and pleura,as well as defensive femoral spines.The new fossil provides clues into early antipredator defensive strategies,allows inferences as to the potential environment and predators,and reveals the mimetic and defensive mechanisms of stick insects from 165 million years ago. | Hongru Yang Chaofan Shi Michael S.Engel Zhipeng Zhao Dong Ren Taiping Gao | 2021 | National Science Review2021，8，1： | 1 |
| 6 | Revealing the role of microalgae-bacteria niche for boosting wastewater treatment and energy reclamation in response to temperature显示文摘Conventional biological treatment usually cannot achieve the same high water quality as advanced treatment when conducted under varied temperatures.Here,satisfactory wastewater treatment efficiency was observed in a microalgae-bacteria consortia(MBC)over a wide temperature range because of the predominance of microalgae.Microalgae contributed more toward wastewater treatment at low temperature because of the unsatisfactory performance of the accompanying bacteria,which experienced cold stress(e.g.,bacterial abundance below 3000 sequences)and executed defensive strategies(e.g.,enrichment of cold-shock proteins).A low abundance of amoA-C and hao indicated that conventional nitrogen removal was replaced through the involvement of microalgae.Diverse heterotrophic bacteria for nitrogen removal were identified at medium and high temperatures,implying this microbial niche treatment contained diverse flexible consortia with temperature variation.Additionally,pathogenic bacteria were eliminated through microalgal photosynthesis.After fitting the neutral community model and calculating the ecological niche,microalgae achieved a maximum niche breadth of 5.21 and the lowest niche overlap of 0.38,while the accompanying bacterial community in the consortia were shaped through deterministic processes.Finally,the maximum energy yield of 87.4 kJ L^(-1)and lipid production of 1.9 g L^(-1)were achieved at medium temperature.Altogether,this study demonstrates that advanced treatment and energy reclamation can be achieved through microalgae-bacteria niche strategies. | Chaofan Zhang Xi Chen Meina Han Xue Li Haixing Chang Nanqi Ren Shih-Hsin Ho | 2023 | Environmental Science and Ecotechnology2023，，2： | 0 |
| 7 | A universal strategy for achieving dual cross-linked networks to obtain ultralong polymeric room temperature phosphorescence显示文摘Efficient polymeric room-temperature phosphorescence(PRTP)with excellent processability and flexibility is highly desirable but still faces formidable challenge.Herein,a general strategy is developed for efficient PRTP through photo-polymerization of phosphor monomers and N-isopropylacrylamide(NIPAM)spontaneously without a crosslinker.Remarkably ultralong lifetime of 3.54 s with afterglow duration time of 25 s and decent phosphorescent quantum efficiency of 13%are achieved.This efficient PRTP has been demonstrated to be derived from the synergistic effect of the covalent and hydrogen bonds networks formed through photo-polymerization of NIPAM.The electron paramagnetic resonance(EPR)spectra confirmed that methyl radicals are generated under the irradiation of ultraviolet light and promote the formation of covalent cross-linking networks.This strategy has also been proved to be generalizable to several other phosphor monomers.Interestingly,the polymer films display ultrahigh temperature resistance with long afterglows even at 140℃ and unexampled ultralong lifetime of 2.45 s in aqueous solutions.This work provides a simple and feasible avenue to obtain efficient PRTP. | Yifan Niu Yan Guan Chunye Long Chaofan Ren Jiwen Lu Chanjuan Jin Ping Wang Xinghe Fan He-Lou Xie | 2023 | Science China Chemistry2023，66，4： | 0 |

| 9 | Modified Coffin-Manson equation to predict the fatigue life of structural materials subjected to mechanical-thermal coupling non-coaxial loading显示文摘With regard to the structures subjected to severe mechanical-thermal coupling fatigue conditions,the consistency between service conditions and loading conditions was the prerequisite for the fatigue prop-erties test and fatigue life prediction.A miniature piezoelectric-driven instrument integrating with a tripodal piezoelectric actuator and envelope-type heating function was developed to investigate the mechanical-thermal coupling fatigue properties and obtain the fatigue life of materials under approximate service conditions.A physical model was described to quantitatively calculate the alternating deformation under the mechanical-thermal coupling tensile-bending combined condition.Accordingly,a fatigue life prediction method based on the Coffin-Manson equation under tensile-bending combined loading was proposed to estimate the mechanical-thermal coupling fatigue life in terms of the total coupling defor-mation and plastic strain amplitude.The feasibility of the proposed instrument was verified through the analysis of displacement responses of high entropy alloy specimens under the thermal-mechanical cou-pling tensile-bending combined condition at temperatures ranging from RT to 600°C.The comparison between fatigue lives directly measured through thermal-mechanical coupling experiments and theoreti-cally predicted fatigue lives indicated the availability of the modified Coffin-Manson equation. | Zhichao Ma Chaofan Li Wei Zhang Shenghui Wang Jiakai Li Hongwei Zhao Luquan Ren | 2023 | Journal of Materials Science & Technology2023，，29： | 0 |
| 10 | Multistage defense response of microalgae exposed to pharmaceuticals in wastewater显示文摘Recently, the use of microalgae for bioremediation of pharmaceuticals(Ph As) has attracted increasing interest. However, most studies focused more on microalgae removal performance, its defensive response to the Ph As during wastewater treatment remains unexplored. Herein, microalgal three defensive systems have been investigated in synthetic wastewater, with six Ph As as the typical drug. Results show that Ph As could bind to EPS, and this action in turn could help to alleviate the direct toxicity of Ph As to microalgae. Subsequently, the physiological analyses revealed the increase of superoxide dismutase(SOD), catalase(CAT), and peroxidase(POD) activities, potentially reducing the oxidative stress induced by Ph As. Furthermore, the enzyme activities of cytochrome P450(CYP450) and glutathione-S-transferase(GST) were significantly upregulated after exposure to SMX, CIP and BPA, followed by a significant decrease in biodegradation rates after the addition of CYP450 inhibitors, suggesting that the biotransformation and detoxification of Ph As occurred. Meanwhile, molecular docking further revealed that CYP450 could bind with Ph As via hydrogen bond and hydrophobic interaction, which proved their abilities to be metabolized and form transformation products in microalgae. These findings provide an advancing understanding of microalgae technologies to improve the treatment of wastewater contaminated with Ph As. | Yuhao Chu Chaofan Zhang Xi Chen Xue Li Nanqi Ren Shih-Hsin Ho | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
