| 1 | Time-frequency response spectrum of rotational ground motion and its application显示文摘The rotational seismic motions are estimated from one station records of the 1999 Jiji (Chi-Chi), Taiwan, earthquake based on the theory of elastic plane wave propagation. The time-frequency response spectrum (TFRS) of the rota-tional motions is calculated and its characteristics are analyzed, then the TFRS is applied to analyze the damage mechanism of one twelve-storey frame concrete structure. The results show that one of the ground motion components can not reflect the characteristics of the seismic motions completely; the characteristics of each component, especially rotational motions, need to be studied. The damage line of the structure and TFRS of ground motion are important for seismic design, only the TFRS of input seismic wave is suitable, the structure design is reliable. | Wei Che Qifeng Luo | 2010 | Earthquake Science2010，23，1： | 15 |
| 2 | Torsional phenomena in 2008 great Wenchuan earthquake显示文摘It is well known that there are some torsional damages in earthquakes. In Taibai park, Jiangyou city, Sichuan province, most of the stone statues, which were placed upon the banisters of one zigzag bridge, exhibited different torsional phenomena in 2008 Wenchuan earthquake. This paper introduces the torsional phenomena of all the statues on the zigzag bridge firstly. Then one eccentricity model is established and the equivalent rotational accelerations are calculated in order to analyze the causes of the torsional damage. In addition, the torsional components are synthesized by using translation accelerations recorded at Jiangyou station in the Wenchuan earthquake. The results show that the equivalent rotational acceleration is larger than the synthesized rotational components, which suggests that the torsional phenomena of the statues on the zigzag bridge might mainly come from its eccentricity. The comparison between the estimated torsional component at Jiangyou and that presented by Trifunac shows that they are in the same order. The research im-plies that the torsional phenomena in earthquakes are very complicated, and not only caused by torsional motions. | Fan Yang Qifeng Luo Wei Che | 2010 | Earthquake Science2010，23，1： | 4 |

| 4 | SCUBE2 mediates bone metastasis of luminal breast cancer by modulating immune-suppressive osteoblastic niches显示文摘Estrogen receptor (ER)-positive luminal breast cancer is a subtype with generally lower risk of metastasis to most distant organs. However, bone recurrence occurs preferentially in luminal breast cancer. The mechanisms of this subtype-specific organotropism remain elusive. Here we show that an ER-regulated secretory protein SCUBE2 contributes to bone tropism of luminal breast cancer. Single-cell RNA sequencing analysis reveals osteoblastic enrichment by SCUBE2 in early bone-metastatic niches. SCUBE2 facilitates release of tumor membrane-anchored SHH to activate Hedgehog signaling in mesenchymal stem cells, thus promoting osteoblast differentiation. Osteoblasts deposit collagens to suppress NK cells via the inhibitory LAIR1 signaling and promote tumor colonization. SCUBE2 expression and secretion are associated with osteoblast differentiation and bone metastasis in human tumors. Targeting Hedgehog signaling with Sonidegib and targeting SCUBE2 with a neutralizing antibody both effectively suppress bone metastasis in multiple metastasis models. Overall, our findings provide a mechanistic explanation for bone preference in luminal breast cancer metastasis and new approaches for metastasis treatment. | Qiuyao Wu Pu Tian Dasa He Zhenchang Jia Yunfei He Wenqian Luo Xianzhe Lv Yuan Wang Peiyuan Zhang Yajun Liang Wenjin Zhao Jun Qin Peng Su Yi-Zhou Jiang Zhi-Ming Shao Qifeng Yang Guohong Hu | 2023 | Cell Research2023，33，6： | 1 |

| 7 | Progress of all-perovskite tandem solar cells:the role of narrow-bandgap absorbers显示文摘Perovskite solar cells(PSCs)have gained increasing attention due to their excellent photovoltaic performance,achieving certified power conversion efficiency(PCE)of 25.2%.To further enhance PCE and break the Shockley-Queisser limit of the single junction PSCs,great efforts have been made in tandem solar cells based on perovskite,including perovskite/Si,and perovskite/perovskite(all-perovskite).Among them,all-perovskite tandem solar cells exhibit unique advantages of both lowcost fabrication and high efficiency.They have advanced rapidly in these years,due to the realization of stable and efficient narrow-bandgap perovskites.In this work,we review the development of monolithic all-perovskite tandem solar cells and highlight the critical role of narrow-bandgap perovskites in recent progress of all-perovskite solar cells.We also propose our perspective of future directions on this subject. | Xinhui Luo Tianhao Wu Yanbo Wang Xuesong Lin Hongzhen Su Qifeng Han Liyuan Han | 2021 | Science China Chemistry2021，64，2： | 1 |

| 10 | Robust multi-sensor image matching based on normalized self-similarity region descriptor显示文摘Multi-modal image matching is crucial in aerospace applications because it can fully exploit the complementary and valuable information contained in the amount and diversity of remote sensing images.However,it remains a challenging task due to significant non-linear radiometric,geometric differences,and noise across different sensors.To improve the performance of heterologous image matching,this paper proposes a normalized self-similarity region descriptor to extract consistent structural information.We first construct the pointwise self-similarity region descriptor based on the Euclidean distance between adjacent image blocks to reflect the structural properties of multi-modal images.Then,a linear normalization approach is used to form Modality Independent Region Descriptor(MIRD),which can effectively distinguish structural features such as points,lines,corners,and flat between multi-modal images.To further improve the matching accuracy,the included angle cosine similarity metric is adopted to exploit the directional vector information of multi-dimensional feature descriptors.The experimental results show that the proposed MIRD has better matching accuracy and robustness for various multi-modal image matching than the state-of-the-art methods.MIRD can effectively extract consistent geometric structure features and suppress the influence of SAR speckle noise using non-local neighboring image blocks operation,effectively applied to various multi-modal image matching. | Xuecong LIU Xichao TENG Jing LUO Zhang LI Qifeng YU Yijie BIAN | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |
| 11 | Clinical Effect of an Improved Post-Operative Feeding Protocol“in Transition”Infants of Congenital Heart Disease with Pulmonary Hypertension显示文摘Background:To achieve successful management of infants with congenital heart disease(CHD)together with pulmonary hypertension(PH),postoperative care,especially feeding care is vital in addition to surgery.Postoperative feeding is comprised of three stages:feeding in the intensive care unit,feeding in the general ward and family feeding,in which the general ward is considered as the“transitional stage”.At present,there is little research on the optimal mode of feeding care for the transitional stage,and there is no universally recognized and accepted protocol.Methods:We retrospectively analyzed 114 CHD infants with PH who underwent family-centered(FC)feeding care from July 2017 to December 2018,and prospectively studied 122 CHD infants with the same baseline level who adopted the improved mode,nurse-parent-driven(NPD)feeding mode from January 2019 to June 2020.The feasibility and efficacy of NPD as a“transitional”feeding nursing mode in CHD infants with PH were compared with the FC cohort by observing and analyzing the stress of family caregivers,feedingrelated complications,the proportion of breastfeeding,improvement of nutritional status,acquisition of knowledge and skills of feeding care,inpatient’s satisfaction rating and prognosis.Results:When compared with the FC feeding care,the NPD mode significantly reduced the burden of family caregivers,improved the rate of feeding care knowledge and skills and inpatient’s satisfaction rating,reduced the incidence of improper feeding-related complications,and enhanced the proportion of breastfeeding and nutritional status of infants at the“transitional stage”(all P<0.05).The self-assessment score of care ability of family caregivers and weight gain of children in the NPD group were significantly higher than those in the FC group(all P<0.05)during the follow-up.Conclusions:As a transitional mode of feeding in CHD infants with PH,NPD feeding care is superior to the conventional FC mode,which therefore can be adopted as a standard protocol in clinical practice. | Huaying He Zhiyong Lin Yuelan Weng Jianjie Zhou Man Ye Xiaowei Luo Qifeng Zhao | 2021 | Congenital Heart Disease2021，16，6： | 0 |
| 12 | Dithienylethene metallodendrimers with high photochromic efficiency显示文摘It has been challenging to achieve multi-photochromic systems without affecting the individual photoswitching properties of the constituent units. Herein, we present the design and synthesis of a new family of platinum-acetylide dendrimers containing up to twenty-one photochromic dithienylethene(DTE)units that exhibit both high photochromic efficiency and individual switching properties. Upon irradiation with ultraviolet(UV) and visible(vis) light, the resultant metallodendrimers display high conversion yield and good fatigue resistance. More interestingly, cyclization-cycloreversion kinetics revealed that the photochromic property of each DTE unit in these metallodendrimers is unaffected by its neighbor and the full ring-closure of up to twenty-one DTE units in one single dendrimer has been achieved. | Yuxuan Wang Qifeng Zhou Xiaoxiao He Ying Zhang Hongwei Tan Jianhua Xu Cuihong Wang Wei Wang Xiping Luo Jinquan Chen Lin Xu | 2022 | Chinese Chemical Letters2022，33，3： | 0 |
| 13 | Quantum simulation of a general anti-PT-symmetric Hamiltonian with a trapped ion qubit显示文摘Non-Hermitian systems satisfying parity-time(PT)symmetry have aroused considerable interest owing to their exotic features.Anti-PT symmetry is an important counterpart of the symmetry,and has been studied in various classical systems.Although a Hamiltonian with anti-PT symmetry only differs from its PT-symmetric counterpart in a global phase,the information and energy exchange between systems and environment are different under them.It is also suggested theoretically that anti-PT symmetry is a useful concept in the context of quantum information storage with qubits coupled to a bosonic bath.So far,the observation of anti-PT symmetry in individual quantum systems remains elusive.Here,we implement an anti-PT-symmetric Hamiltonian of a single qubit in a single trapped ion by a designed microwave and optical control-pulse sequence.We characterize the anti-PT phase transition by mapping out the eigenvalues at different ratios between coupling strengths and dissipation rates.The full information of the quantum state is also obtained by quantum state tomography.Our work allows quantum simulation of genuine open-system feature of an anti-PT-symmetric system,which paves the way for utilizing non-Hermitian properties for quantum information processing. | Ji Bian Pengfei Lu Teng Liu Hao Wu Xinxin Rao Kunxu Wang Qifeng Lao Yang Liu Feng Zhu Le Luo | 2023 | Fundamental Research2023，3，6： | 0 |
