1Intelligent metasurfaces:control,communication and computing显示文摘Controlling electromagnetic waves and information simultaneously by information metasurfaces is of central importance in modern society.Intelligent metasurfaces are smart platforms to manipulate the wave-information-matter interactions without manual intervention by synergizing engineered ultrathin structures with active devices and algorithms,which evolve from the passive composite materials for tailoring wave-matter interactions that cannot be achieved in nature.Here,we review the recent progress of intelligent metasurfaces in wave-information-matter controls by providing the historical background and underlying physical mechanisms.Then we explore the application of intelligent metasurfaces in developing novel wireless communication architectures,with particular emphasis on metasurface-modulated backscatter wireless communications.We also explore the wave-based computing by using the intelligent metasurfaces,focusing on the emerging research direction in intelligent sensing.Finally,we comment on the challenges and highlight the potential routes for the further developments of the intelligent metasurfaces for controls,communications and computing.Lianlin Li Hanting Zhao Che Liu Long Li Tie Jun Cui 2022eLight2022,2,1:7
2Middle Jurassic-early Cretaceous radiolarian assemblages of the western Yarlung Zangbo Suture Zone: Implications for the evolution of the Neo-Tethys显示文摘Cherts in the Zhongba melange of the western Yarlung Zangbo Suture Zone(YZSZ) contain well preserved radiolarian assemblages. These radiolarian assemblages indicate that the Zhongba melange has middle Jurassic-early Cretaceous remnant, are coeval with those from the central and eastern parts of the YZSZ. Cherts from the Najiu area yield Aalenian to Aptian radiolarians, while cherts interbedded with siliceous mudstones from the Bielongjiala area yield Aptian radiolarians, indicating that terrigenousderived sediments were deposited during early Aptian. The above observations indicate that the entire YZSZ have a similar geochronological framework and thus they underwent similar geological evolution:(1) during the Jurassic, the Neo-Tethys was a wide ocean with pelagic sediments distal from continents;(2) during the Cretaceous(around 130-120 Ma), the Neo-Tethys started to subduct along the southern margin of the Lhasa block, and terrigenous-derived siliceous mudstone began deposition.Hanting Zhong Jingen Dai Chengshan Wang Yalin Li Yushuai Wei 2017Geoscience Frontiers2017,8,5:6
3Intelligent metasurface imager and recognizer显示文摘There is an increasing need to remotely monitor people in daily life using radio-frequency probe signals.However,conventional systems can hardly be deployed in real-world settings since they typically require objects to either deliberately cooperate or carry a wireless active device or identification tag.To accomplish complicated successive tasks using a single device in real time,we propose the simultaneous use of a smart metasurface imager and recognizer,empowered by a network of artificial neural networks(ANNs)for adaptively controlling data flow.Here,three ANNs are employed in an integrated hierarchy,transforming measured microwave data into images of the whole human body,classifying specifically designated spots(hand and chest)within the whole image,and recognizing human hand signs instantly at a Wi-Fi frequency of 2.4 GHz.Instantaneous in situ full-scene imaging and adaptive recognition of hand signs and vital signs of multiple non-cooperative people were experimentally demonstrated.We also show that the proposed intelligent metasurface system works well even when it is passively excited by stray Wi-Fi signals that ubiquitously exist in our daily lives.The reported strategy could open up a new avenue for future smart cities,smart homes,human-device interaction interfaces,health monitoring,and safety screening free of visual privacy issues.Lianlin Li Ya Shuang Qian Ma Haoyang Li Hanting Zhao Menglin Wei Che Liu Chenglong Hao Cheng-Wei Qiu Tie Jun Cui 2019Light(Science & Applications)2019,8,1:5
4Internal ribosome entry site-based vectors for combined gene therapy显示文摘Gene therapy appears as a promising strategy to treatincurable diseases. In particular, combined gene therapy has shown improved therapeutic efficiency. Internal ribosome entry sites(IRESs), RNA elements naturally present in the 5' untranslated regions of a few m RNAs, constitute a powerful tool to co-express several genes of interest. IRESs are translational enhancers allowing the translational machinery to start protein synthesis by internal initiation. This feature allowed the design of multi-cistronic vectors expressing several genes from a single m RNA. IRESs exhibit tissue specificity, and drive translation in stress conditions when the global cell translation is blocked, which renders them useful for gene transfer in hypoxic conditions occurring in ischemic diseases and cancer. IRES-based viral and non viral vectors have been used successfully in preclinical and clinical assays of combined gene therapy and resulted in therapeutic benefits for various pathologies including cancers, cardiovascular diseases and degenerative diseases.Edith Renaud-Gabardos Fransky Hantelys Florent Morfoisse Xavier Chaufour Barbara Garmy-Susini Anne-Catherine Prats 2015World Journal of Experimental Medicine2015,5,1:4
5CPPU may induce gibberellin-independent parthenocarpy associated with PbRR9 in‘Dangshansu’pear显示文摘Parthenocarpy is a valuable trait in self-incompatible plants,such as pear.N-(2-chloro-4-pyridyl)-N’-phenylurea(CPPU),a synthetic cytokinin analog,can induce parthenocarpy in pear(Pyrus spp.),but the mechanism of induction is unclear.To investigate the role of gibberellin in CPPU-induced parthenocarpy in pear,CPPU supplemented with paclobutrazol(PAC)was sprayed onto‘Dangshansu’pear.We found that the fruit set rate of pear treated with CPPU supplemented with PAC was identical to that in a CPPU-alone treatment group.In regard to cell development,CPPU mainly promoted hypanthium cell division and expansion,and PAC application had no influence on CPPU-induced cell development.RNA sequencing revealed that gibberellin 20 oxidase and gibberellin 3 oxidase genes were not differentially expressed following CPPU treatment.According to the analysis of fruit phytohormone content,the CPPU treatments did not induce gibberellin biosynthesis.These results suggest that CPPU-induced parthenocarpy may be gibberellin independent in‘Dangshansu’pear.After CPPU treatment,the indole acetic acid(IAA)content in fruit was significantly increased,and the abscisic acid(ABA)content was significantly decreased.Similarly,RNA sequencing revealed that many genes involved in the auxin and ABA pathways were significantly differentially expressed in the CPPU treatment groups;among them,indole-3-pyruvate monooxygenase(YUCCA)was significantly upregulated and 9-cis-epoxycarotenoid dioxygenase(NCED)was significantly downregulated.IAA and ABA may thus play important roles in CPPU-induced parthenocarpy.PbTwo-component response regulator9(PbRR9),PbYUCCA4,and PbNCED6 were then selected to further elucidate the mechanism of CPPU-induced parthenocarpy.A yeast one-hybrid assay indicated that PbRR9 can combine with the PbYUCCA4 and PbNCED6 promoters.Dual luciferase assays revealed that PbRR9 can promote and repress the activities of the PbYUCCA4 and PbNCED6 promoters,respectively.After the transient expression of PbRR9 in fruits,PbYUCCA4 expression was significantly upregulated,and PbNCED6 expression was significantly downregulated.This study uncovered a CPPU-induced parthenocarpy mechanism that is different from that in tomato.CPPU may upregulate PbYUCCA4 and downregulate PbNCED6 by upregulating PbRR9,thereby increasing IAA content and decreasing ABA content to ultimately induce parthenocarpy in‘Dangshansu’pear.However,because only a single time point was used and because‘botanical’and‘accessory’fruits have different structures,this conclusion is still preliminary.Liu Cong Ting Wu Hanting Liu Huibin Wang Haiqi Zhang Guangping Zhao Yao Wen Qianrong Shi Lingfei Xu Zhigang Wang 2020Horticulture Research2020,7,1:4
6Heterotopic ossification after the use of recombinant human bone morphogenetic protein-7显示文摘AIM To present the incidence of heterotopic ossification after the use of recombinant human bone morphogenetic protein-7(rhB MP-7) for the treatment of nonunions.METHODS Bone morphogenetic proteins(BMPs) promote bone formation by auto-induction. Recombinant human BMP-7 in combination with bone grafts was used in 84 patients for the treatment of long bone nonunions. All patients were evaluated radiographicaly for the development of heterotopic ossification during the standard assessment for the nonunion healing. In all patients(80.9%) with radiographic signs of heterotopic ossification, a CT scan was performed. Nonunion site palpation and ROM evaluation of the adjacent jointswere also carried out. Factors related to the patient(age, gender), the nonunion(location, size, chronicity, number of previous procedures, infection, surrounding tissues condition) and the surgical procedure(graft and fixation type, amount of rhB MP-7) were correlated with the development of heterotopic ossification and statistical analysis with Pearsons χ~2 test was performed.RESULTS Eighty point nine percent of the nonunions treated with rh BMP-7, healed with no need for further procedures. Heterotopic bone formation occurred in 15 of 84 patients(17.8%) and it was apparent in the routine radiologi-cal evaluation of the nonunion site, in a mean time of 5.5 mo after the rh BMP-7 application(range 3-12). The heterotopic ossification was located at the femur in 8 cases, at the tibia in 6, and at the humerus in οne patient. In 4 patients a palpable mass was present and only in one patient, with a para-articular knee nonunion treated with rhB MP-7, the size of heterotopic ossification affected the knee range of motion. All the patients with heterotopic ossification were male. Statistical analysis proved that patient's gender was the only important factor for the development of heterotopic ossification(P = 0.007). CONCLUSION Heterotopic ossification after the use of rh BMP-7 in nonunions was common but it did not compromise the final clinical outcome in most cases, and affected only male patients.Marianthi Papanagiotou Zoe H Dailiana Theophilos Karachalios Sokratis Varitimidis Michael Hantes Georgios Dimakopoulos Marianna Vlychou Konstantinos N Malizos 2017World Journal of Orthopedics2017,8,1:3

8One-bit quantization is good for programmable coding metasurfaces显示文摘The information-carrying programmable metasurfaces have found widespread applications in communication, sensing, and other related areas. However, there is a fundamental but unresolved problem,i.e., the rigorous understanding of the quantization of metasurface coding. Here, we theoretically investigate the performance difference between one-bit and continuous information-encoding metasurfaces. To this end,we derive analytical representations of system responses in various cases(single-input single-output, singleinput multiple-output, and multiple-input multiple-output). We analyze the impact of one-bit coding(in contrast to continuous coding) in terms of the resulting channel cross-talk and reduction of information capacity in various representative scenarios from wireless communication and holography. Our main finding indicates that the one-bit coding yields a satisfactory performance in most practical scenarios;we also show that in many cases there are smart ways to mildly relax optimization constraints in order to reduce the performance gap between the one-bit and continuous coding. We expect that our results can provide theoretical guidance for a large variety of metasurface-assisted information systems for electromagnetic waves and other wave phenomena.Ya SHUANG Hanting ZHAO Menglin WEI Qiang CHENG Shi JIN Tiejun CUI Philipp DEL HOUGNE Lianlin LI 2022Science China(Information Sciences)2022,65,7:2

10Thermodynamics of voltage-gated ion channels显示文摘Ion channels are essential for cellular signaling.Voltage-gated ion channels (VGICs)are the largest and most extensively studied superfamily of ion channels.They possess modular structural features such as voltage-sensing domains that encircle and form mechanical connections with the pore-forming domains.Such features are intimately related to their function in sensing and responding to changes in the membrane potential.In the present work,we discuss the thermodynamic mechanisms of the VGIC superfamily,including the two-state gating mechanism,sliding-rocking mechanism of the voltage sensor,subunit cooperation,lipid-infiltration mechanism of inactivation,and the relationship with their structural features.Xuejun C.Zhang Hanting Yang Zhenfeng Liu Fei Sun 2018Biophysics Reports2018,4,6:2

13Construction of a fluvial facies knowledge graph and its application in sedimentary facies identification显示文摘Lithofacies paleogeography is a data-intensive discipline that involves the interpretation and compilation of sedimentary facies.Traditional sedimentary facies analysis is a labor-intensive task with the added complexity of using unstructured knowledge and unstandardized terminology.Therefore,it is very difficult for beginners or non-geology scholars who lack a systematic knowledge and experience in sedimentary facies analysis.These hurdles could be partly alleviated by having a standardized,structured,and systematic knowledge base coupled with an efficient automatic machine-assisted sedimentary facies identification system.To this end,this study constructed a knowledge system for fluvial facies and carried out knowledge representation.Components include a domain knowledge graph for types of fluvial facies(meandering,braided and other fluvial depositional environments)and their characteristic features(bedforms,grain size distribution,etc.)with visualization,a method for query and retrieval on a graph database platform,a hierarchical knowledge tree-structure,a data-mining clustering algorithm for machineanalysis of publication texts,and an algorithm model for this area of sedimentary facies reasoning.The underlying sedimentary facies identification and knowledge reasoning system is based on expert experience and synthesis of publications.For testing,17 sets literature publications data that included details of sedimentary facies data(bedforms,grain sizes,etc.)were submitted to the artificial intelligence model,then compared and validated.This testing set of automated reasoning results yielded an interpretation accuracy of about 90%relative to the published interpretations in those papers.Therefore,the model and algorithm provide an efficient and automated reasoning technology,which provides a new approach and route for the rapid and intelligent identification of other types of sedimentary facies from literature data or direct use in the field.Lei Zhang Mingcai Hou Anqing Chen Hanting Zhong James G.Ogg Dongyu Zheng 2023Geoscience Frontiers2023,14,2:1
