| 2 | Oxygen-assisted spinodal structure achieves 1.5 GPa yield strength in a ductile refractory high-entropy alloy显示文摘Refractory high-entropy alloys(RHEAs)with room-temperature ductility are drawing growing attention for potential high-temperature applications.However,the most widely used metallurgical mechanisms appear weak in optimizing their strength and ductility.Here,we report that the nanoscale spinodal struc-ture in Ti_(41)V_(27)Hf_(15)Nb_(15)O_(2)leads to the highest tensile yield strength(∼1.5 GPa)among the existing RHEAs and good elongation of∼12%.With the aid of thermodynamic calculations,we show that oxygen plays a dominant role in controlling the formation of the spinodal structure by influencing the spinodal gap of the Ti-V-Hf-Nb system.Exploring the atomic structure of the spinodal structure(β+β^(∗)),we showed that the large lattice misfit of the spinodal phases is mainly responsible for the excellent strengthen-ing effect while the planar to wavy dislocation glide mode transition accounts for the retained ductility.This work provides a novel strategy to improve the mechanical properties of the RHEAs and deepens the understanding of their phase stabilities. | Dingcong Cui Yuyu Zhang Linxiang Liu Yue Li Lei Wang Zhijun Wang Junjie Li Jincheng Wang Feng He | 2023 | Journal of Materials Science & Technology2023,,26: | 1 |

| 4 | Quantum information transfer between a two-level and a four-level quantum systems显示文摘Quantum mechanics provides a disembodied way to transfer quantum information from one quantum object to another.In theory,this quantum information transfer can occur between quantum objects of any dimension,yet the reported experiments of quantum information transfer to date have mainly focused on the cases where the quantum objects have the same dimension.Here,we theoretically propose and experimentally demonstrate a scheme for quantum information transfer between quantum objects of different dimensions.By using an optical qubit-ququart entangling gate,we observe the transfer of quantum information between two photons with different dimensions,including the flow of quantum information from a four-dimensional photon to a twodimensional photon and vice versa.The fidelities of the quantum information transfer range from 0.700 to 0.917,all above the classical limit of 2/3.Our work sheds light on a new direction for quantum information transfer and demonstrates our ability to implement entangling operations beyond two-level quantum systems. | TIANFENG FENG QIAO XU LINXIANG ZHOU MAOLIN LUO WUHONG ZHANG XIAOQI ZHOU | 2022 | Photonics Research2022,10,12: | 0 |
| 5 | eALT-F:A New Non-Invasive Staging Method to Identify Medium to High-Risk Patients with HCC from Ultra-High HBV Viral Load Population—China,2010-2023显示文摘Background:The objective of this study was to examine the clinical characteristics of individuals with ultra-high hepatitis B virus(HBV)viral load and develop a novel staging method for chronic hepatitis B(CHB)that can more effectively identify patients with medium to high hepatocellular carcinoma(HCC)risk.Methods:A total of 2,118 patients with HBV DNA>1×10^(7) IU/mL who visited Peking University People’s Hospital between January 2010 and March 2023 were enrolled retrospectively.Clinical data from the first visit were obtained and analyzed.The traditional phases and new‘eALT-F’stages were compared to evaluate the risk of HCC.Results:In the overall patients,more than onethird of the patients were under 30 years old.Additionally,a small proportion of older people(>60 years)also had ultra-high HBV viral load(4.3%).9.1%and 6.7%of individuals with ultra-high HBV viral load showed FIB-4>3.25 and aMAP≥50,respectively.In the traditional stages of CHB,which are based on HBeAg and alanine aminotransferase(ALT)[the upper limit of normal(ULN)ALT level at 40 IU/L for both men and women],regardless of phase,a certain proportion of patients were at risk of developing HCC(4.1%,6.4%,25.0%,and 20.3%).However,in the new‘eALT-F’stages,which are based on HBeAg,ALT(the ULN of ALT level at 30 IU/L for men and 19 IU/L for women),and/or FIB-4 levels(>1.45),aMAP≥50 was only observed in chronic hepatitis patients with positive or negative HBeAg(6.4%and 22.1%,respectively).Conclusions:The‘eALT-F’staging method,based on HBeAg,ALT(males:the ULN of ALT was 30 IU/L,females:19 IU/L)and/or FIB-4 levels,was more effective in identifying medium to high-risk patients with HCC from patients with ultra-high HBV viral load than the traditional staging methods. | Jiarui Zheng Xiaoxiao Wang Zilong Wang Linxiang Huang Yandi Xie Suzhen Jiang Bo Feng | 2023 | China CDC weekly2023,5,49: | 0 |
