1Energy analysis and criteria for structural failure of rocks显示文摘The intrinsic relationships between energy dissipation,energy release,strength and abrupt structural failure are key to understanding the evolution of deformational processes in rocks.Theoretical and experimental studies confirm that energy plays an important role in rock deformation and failure.Dissipated energy from external forces produces damage and irreversible deformation within rock and decreases rock strength over time.Structural failure of rocks is caused by an abrupt release of strain energy that manifests as a catastrophic breakdown of the rock under certain conditions.The strain energy released in the rock volume plays a pivotal role in generating this abrupt structural failure in the rocks.In this paper,we propose criteria governing(1) the deterioration of rock strength based on energy dissipation and(2) the abrupt structural failure of rocks based on energy release.The critical stresses at the time of abrupt structural failure under various stress states can be determined by these criteria.As an example,the criteria have been used to analyze the failure conditions of surrounding rock of a circular tunnel.Heping Xie Liyun Li Ruidong Peng Yang Ju 2009Journal of Rock Mechanics and Geotechnical Engineering2009,1,1:39
2The AGL6-like gene OsMADS6 regulates floral organ and meristem identities in rice显示文摘Although AGAMOUS-LIKE6 (AGL6) MADS-box genes are ancient with wide distributions in gymnosperms and angiosperms, their functions remain poorly understood. Here, we show the biological role of the AGL6-1ike gene, OsMADS6, in specifying floral organ and meristem identities in rice (Oryza sativa L.). OsMADS6 was strongly ex- pressed in the floral meristem at early stages. Subsequently, OsMADS6 transcripts were mainly detectable in paleas, lodicules, carpels and the integument of ovule, as well as in the receptacle. Compared to wild type plants, osmads6 mutants displayed altered palea identity, extra glume-like or mosaic organs, abnormal carpel development and loss of floral meristem determinacy. Strikingly, mutation of a SEPALLATA (SEP)-like gene, OsMADS1 (LHS1), enhanced the defect of osmads6 flowers, and no inner floral organs or glume-like structures were observed in whorls 2 and 3 of osmadsl-z osmads6-1 flowers. Furthermore, the osmadsl-z osmads6-1 double mutants developed severely indetermi- nate floral meristems. Our finding, therefore, suggests that the ancient OsMADS6 gene is able to specify 'floral state' by determining floral organ and meristem identities in monocot crop rice together with OsMADS1.Haifeng Li Wanqi Liang Ruidong Jia Changsong Yin Jie Zong Hongzhi Kong Dabing Zhang 2010Cell Research2010,20,3:33
3Energy analysis for damage and catastrophic failure of rocks显示文摘The development history and current state of studies on the characteristics and mechanisms of deformation and failure of rock materials were briefly reviewed from the viewpoint of energy.The main scope and the achievable objectives of the energy-based research system were expatiated.It was validated by experiments that the damage process of rocks can be well described by the rock damage evolution equation established based on energy dissipation.It was found from the uniaxial compression and biaxial compression tests that only a small proportion of the total input energy in hard rocks is dissipated before peak load and a large proportion in soft rocks is dissipated before peak load.For both hard and soft rocks,the energy dissipated after peak load accounts for a greater proportion.More energy would be required for rock failure under equal biaxial compression than under unequal biaxial compression.The total absorbed energy is different for rock failure under high-rate loading and low-rate loading.More fragmented failure pattern usually corresponds to higher energy absorption.The mesoscopic analysis on the damage and failure of bedded salt rocks showed that the energy dissipation is prominent and the total absorbed energy for rock failure is low when cracks propagate in the weak mud interlayer while it is contrary when cracks propagate in the salt rock.The energy accumulation,transfer,dissipation and release during the failure process of tunnel with impending failure under disturbance were analyzed theoretically based on the elastoplastic mechanics theory.Furthermore,the spatial distribution of energy dissipation and energy release of fractured rocks under unloading was simulated numerically.It was demonstrated that energy is likely to be released from the weakest surface under compression,which triggers the global failure of rocks.XIE HePing 1,2,LI LiYun 2,1,JU Yang 2,PENG RuiDong 2 & YANG YongMing 2 1 Sichuan University,Chengdu 610065,China 2 State Key Laboratory of Coal Resources and Safe Mining,Beijing Key Laboratory of Fracture and Damage Mechanics of Rock and Concrete,China University of Mining and Technology,Beijing 100083,China 2011Science China(Technological Sciences)2011,54,S1:29
4Home range and seasonality of Yunnan snub-nosed monkeys显示文摘Home range studies are essential for understanding an animal’s behavioral ecology and for making wildlife conservation efficient.The home range of a group of Yunnan snub-nosed monkeys(Rhinopithecus bieti Milne-Edwards,1897)was estimated using a global positioning system collar from December 2003 to October 2004 in northern Yunnan Province,China.To measure the ranging area of the study group 1291 animal locations were fixed.Based on the 100%minimum convex polygon method,the home range size was approximately 32.8 km2;based on the grid-cell method it was approximately 17.8 km2 using a 250-m grid and 23.3 km2 using a 500-m grid.We assessed seasonal changes in the home range of this monkey population and found a different ranging pattern of from earlier studies.Daily range size was calculated as 4.80±5.81 ha(mean±standard deviation),with a range of 45.66 ha(0.01–45.67 ha).Baoping REN Ming LI Yongcheng LONG Ruidong WU Fuwen WEI 2009Integrative Zoology2009,4,2:3

6Soliton and bound-state soliton mode-locked fiber laser based on a MoS_2/fluorine mica Langmuir–Blodgett film saturable absorber显示文摘In this article, we report on an experimentally generated soliton and bound-state soliton passively mode-locked erbium-doped fiber laser by incorporating a saturable absorber(SA) made of MoS2∕fluorine mica(FM) that was fabricated with the Langmuir–Blodgett(LB) method. The FM substrate is 20 μm thick and easy to bend or cut,like a polymer. However, it has a higher damage threshold and a better thermal dissipation than polymers.In addition, the LB method can be used to fabricate a thin film with good uniformity. In this study, the modulation depth, saturable intensity, and unsaturated loss of the SA are measured as 5.9%, 57.69 MW∕cm2, and13.4%, respectively. Based on the SA, a soliton mode-locked laser is achieved. The pulse duration, repetition rate, and signal-to-noise ratio are 581 fs, 15.67 MHz, and 65 dB, respectively. By adjusting the polarization controller and pump power, we obtain a bound-state soliton mode-locked pulse. The temporal interval between the two solitons forming the bound-state pulse is 2.7 ps. The repetition rate of the bound-state pulses is proportional to the pump power. The maximum repetition rate is 517 MHz, corresponding to the 33 rd harmonic of the fundamental repetition rate. The results indicate that the MoS2∕FM LB film absorber is a promising photonic device in ultrafast fiber lasers.RUIDONG Lü YONGGANG WANG JIANG WANG WEI REN LU LI SICONG LIU ZHENDONG CHEN YONGFANG LI HONGYING WANG FUXING FU 2019Photonics Research2019,7,4:2

9A novel TIR-NBS-LRR gene regulates immune response to Phytophthora root rot in soybean显示文摘Phytophthora root rot(PRR),caused by Phytophthora sojae,is a devastating disease of soybean.The NBSLRR gene family is a class of plant genes involved in disease resistance.miRNA mediates plant response to biotic stresses by regulating the expression of target genes at the transcriptional or post-translational level.Glyma.16G135500,encoding an NBS-LRR-type protein,is a target of gma-miR1510 that responds to pathogen infections.We cloned and overexpressed Glyma.16G135500(naming it GmTNL16)and knocked down mi R1510 using short tandem target mimic technology to identify the roles of the GmTNL16/gma-mi R1510 pair in the interaction of soybean and the oomycete.By overexpressing GmTNL16 in transgenic hairy roots of soybean,we showed that biomass of P.sojae was lower in overexpressing hairy roots than in control roots.Thus,miR1510 expression was reduced upon P.sojae infection,reflecting the induced expression of GmTNL16 conferring resistance to P.sojae in soybean.Differentially expressed genes were enriched in plant-pathogen interaction,plant hormone signal transduction,and secondary metabolism by RNA sequencing analyze.In particular,jasmonate and salicylic acid pathway-associated genes,including JAZ,COI1,TGA,and PR,responded to P.sojae infection.All of these results indicate that the GmTNL16/gma-miR1510 pair participates in soybean defense response via the JA and SA pathways.Li Zhou Sushuang Deng Huidong Xuan Xingxing Fan Ruidong Sun Jinming Zhao Haitang Wang Na Guo Han Xing 2022The Crop Journal2022,10,6:1

11The impact of sulfate reduction on the distribution of methylmercury in reservoirs in the city of Guiyang显示文摘In this paper, the relationship between sulfate reduction potential and mercury methylation potential was studied in the Aha, Baihua and Hongfeng reservoirs from Guiyang City. The methylmercury (MeHg) concentrations of lake water in the Aha Reservoir were greatly elevated as compared to those of the Hongfeng and Baihua reservoirs, which was correlated with its distinctly high SRB abundance, SO42-, and S2- concentrations. Among the three reservoirs, however, the highest MeHg was observed in in the top several centimenters of pore water profile in the Hongfeng Reservoir where the lowest S2- in pore water occurred. The distributions of MeHg in lake water and pore water showed the highest methylation potential occurred at water-sediment surface for the Aha Reservoir and the in the top several centimenters of sediments for the Hongfeng Reservoir. It is guessed that the highest mercury methylation only occurs at the sites with certain sulfide concentrations.HE Tianrong LI Ting Yang Ruidong LUO Guangjun LANG Xiaofang An Yanling YAN Haiyu 2013Chinese Journal Of Geochemistry2013,32,1:1

15Generative adversarial networks enhanced location privacy in 5G networks显示文摘5G networks,as the up-to-date communication platforms,are experiencing fast booming.Meanwhile,increasing volumes of sensitive data,especially location information,are being generated and shared using 5G networks for various purposes ceaselessly.Location and trajectory information in the published data has always been and will keep courting risks and attacks by malicious adversaries.Therefore,there are still privacy leakage threats by simply sharing the original data,especially data with location information,due to the short cover range of 5G signal tower.To better address these issues,we proposed a generative adversarial networks(GAN)enhanced location privacy protection model to cloak the location and even trajectory information.We use posterior sampling to generate a subset of data,which is proved complying with differential privacy requirements from the end device side.After that,a data augmentation algorithm modified from classic GAN is devised to generate a series of privacy-preserving full-sized synthetic data from the central server side.With the synthetic data generated from a real-world dataset,we demonstrate the superiority of the proposed model in terms of location privacy protection,data utility,and prediction accuracy.Youyang QU Jingwen ZHANG Ruidong LI Xiaoning ZHANG Xuemeng ZHAI Shui YU 2020Science China(Information Sciences)2020,63,12:1

20Synergistic oxidation-reforming of biomass for high quality syngas production based on a bifunctional catalyst显示文摘Conventional O_(2)gasification for low-rank biomass/sludge conversion is prone to high CO_(2)concentrations in the syngas because of its high O content and low calorific value.This study establishes a synergistic oxidationreforming reaction route for the conversion of low-rank carbon-containing resources into high-quality syngas.The efficient oxidation-reforming reaction is based on the bifunctional catalyst NiO-Fe2O3/Al2O3,which includes Fe2O3 oxidation sites and NiO reforming sites.Hydrogen temperature-programmed reduction,together with X-ray diffraction and X-ray photoelectron spectroscopy experiments,demonstrated that the two functional active sites have strong interactions with the support,leading to efficient cooperation between the oxidation reaction and reforming reaction with regards to both the reaction sequence and C/H/O element balance.Syngas produced from biomass/sludge based on oxidation-reforming reactions has an extremely low CO_(2)concentration of approximately 3%,and the valid gas(CO,H_(2))concentration exceeds 95%.The valid gas yield of walnut shell reached 1452.9 mL/g,the total gas yield was 1507.2 mL/g,and the H_(2)/CO ratio was 1.02,which are all very close to the theoretical maximum values of 1553.1 mL/g and 1.01,respectively,demonstrating that the inherent CO_(2)/H_(2)O along with CH4/tar species were efficiently converted to H_(2)and CO through oxidation-reforming reactions.During a 60-cycle test,NiO-Fe2O3/Al2O3 exhibited good redox stability.Tao He Dan Zhang Wenqing Chen Zeng Liu Ruidong Zhao Jianqing Li Jingli Wu Zhiqi Wang Jinhu Wu 2024Green Carbon2024,2,1:0
