Primary liver cancer,which is mainly composed of hepatocellular carcinoma(HcC),is the sixth most common type of cancer worldwide and the thirdmost common cause of cancer mortality.1 The total number of mutations present in tumor specimens is called tumor mutation burden(TMB)and it is an emerging biomarker of immunotherapy response.2 TMB can predict clinical responses to immunotherapy such as ICl(immune checkpoint inhibitor)treatments and higher TMB is related to better survival.3 TP53,a gene encoding a tumor suppressor protein that triggers apoptosis and cell cycle arrest,is one of the most prevalent mutations in 25%-30%of HCC patients.4 Research shows that TP53 mutations in HCC patients are associated with advanced tumor grade and poor prognosis.5 To identify the TP53 mutation-related genes which can predict HCC patients'prognosis and explore the immune cell infiltration,we constructed a risk model based on six TP53 mutation-related genes which can accurately predict patients'prognosis.Besides,six immune cells with a similar expression pattern were identified in The Cancer Genome Atlas(TCGA)and International Cancer Genome Consortium(ICGC)databases.

Cavity-enhanced single quantum dots(QDs)are the main approach towards ultra-high-performance solid-state quantum light sources for scalable photonic quantum technologies.Nevertheless,harnessing the Purcell effect requires precise spectral and spatial alignment of the QDs’emission with the cavity mode,which is challenging for most cavities.Here we have successfully integrated miniaturized Fabry-Perot microcavities with a piezoelectric actuator,and demonstrated a bright single-photon source derived from a deterministically coupled QD within this microcavity.Leveraging the cavity-membrane structures,we have achieved large spectral tunability via strain tuning.On resonance,a high Purcell factor of~9 is attained.The source delivers single photons with simultaneous high extraction efficiency of 0.58,high purity of 0.956(2)and high indistinguishability of 0.922(4).Together with its compact footprint,our scheme facilitates the scalable integration of indistinguishable quantum light sources on-chip,therefore removing a major barrier to the development of solid-state quantum information platforms based on QDs.

Tsinghua Science and Technology 2024年第2期29卷 343-355页

Ltd.Hangzhou 310000China College of Computer Science and Technology NUDTChangsha 410073China

Time series clustering is a challenging problem due to the large-volume,high-dimensional,and warping characteristics of time series data.Traditional clustering methods often use a single criterion or distance measure,which may not capture all the features of the data.This paper proposes a novel method for time series clustering based on evolutionary multi-tasking optimization,termed i-MFEA,which uses an improved multifactorial evolutionary algorithm to optimize multiple clustering tasks simultaneously,each with a different validity index or distance measure.Therefore,i-MFEA can produce diverse and robust clustering solutions that satisfy various preferences of decision-makers.Experiments on two artificial datasets show that i-MFEA outperforms single-objective evolutionary algorithms and traditional clustering methods in terms of convergence speed and clustering quality.The paper also discusses how i-MFEA can address two long-standing issues in time series clustering:the choice of appropriate similarity measure and the number of clusters.

Polarization and conductance losses are the fundamental dielectric attenuation mechanisms for graphene-based absorbers, but it is not fully understood in revealing the loss mechanism of affect graphene itself. For the first time, the reduced graphene oxide(RGO) based absorbers are developed with regulatory absorption properties and the absorption mechanism of RGO is mainly originated from the carrier injection behavior of trace metal Fe nanosheets on graphene. Accordingly, the minimum reflection loss(RLmin) of Fe/RGO-2composite reaches-53.38 dB(2.45 mm), and the effective absorption bandwidth achieves 7.52 GHz(2.62 mm) with lower filling loading of 2 wt%. Using off-axis electron hologram testing combined with simulation calculation and carrier transport property experiments, we demonstrate here the carrier injection behavior from Fe to graphene at the interface and the induced charge accumulation and rearrangement, resulting in the increased interfacial and dipole polarization and the conductance loss. This work has confirmed that regulating the dielectric property of graphene itself by adding trace metals can not only ensure good impedance matching, but also fully exploit the dielectric loss ability of graphene at low filler content,which opens up an efficient way for designing lightweight absorbers and may be extended to other types materials.

Solid-state electrolytes（SSEs） play a pivotal role in advancing next-generation lithium metal battery technology.However,they commonly encounter substantial interfacial resistance and poor stability when interfacing with lithium metal,hindering practical applications.Herein,we introduce a flexible metal-organic framework（MOF:NUS-6）-incorporated polymeric layer,denoted as NP,designed to protect the sodium superionic conductor（NASICON）-type Li1.3Al0.3Ti1.7（PO4）3（LATP） electrolyte from Li metal anodes.The NP matrix establishes a soft interface with the LATP surface,effectively reducing voids and gaps that may arise between the LATP electrolyte and Li metal.Moreover,the MOF component in NP enhances ionic conductivity,offers abundant Li+transport sites,and provides hierarchical ion channels,ensuring a homogeneous Li+flow and thus effectively inhibiting Li dendrite formation.Utilizing NP,we fabricate Li symmetrical cells cycled for over 1600 h at 0.2 mA cm-2and all-solid-state LiINP-LATPI LiFePO4batteries,achieving a remarkable 99.3% capacity retention after 200 cycles at 0.2 C.This work outlines a general strategy for designing long-lasting and stable solid-state Li metal batteries.

Partial aging can counter-intuitively couple with sulfidation to improve the reactive durability of zerovalent iron

引用

Frontiers of Environmental Science & Engineering 2024年第2期18卷 1-11页

Sulfated zero-valent iron(SZVI)has shown promising applications in wastewater treatment.However,the rapid decline in the reactivity of SZVI with time limits its real practice.To mediate this problem,partial aging was proposed to improve the reactive durability of SZVI.Taking Cr(VI)as the target contaminant,we found that the aged ZVI(AZVI)gradually lost reactivity as aging time increased from 0.5 to 2 d.Counter-intuitively,the partially aged SZVI(ASZVI)showed greater reactivity than SZVI when exposed to oxygenated water for a period ranging from 0.5 to 14 d.In addition,the ASZVI with 0.5 d of aging time(ASZVI-0.5)not only maintained reactivity in successive runs but also increased the Cr(VI)removal capacity from 9.1 mg/g by SZVI to 19.1 mg/g by ASZVI-0.5.Correlation analysis further revealed that the electron transfer from the Fe0 core to the shell was mediated by the conductive FeS and FeS2 in the subshell of ASZVI.Meanwhile,the lepidocrocite and magnetite on the surface of ASZVI facilitated Cr(VI)adsorption and subsequent electron transfer for Cr(VI)reduction.Moreover,the iron(hydr)oxide shell could retain the conductive FeS and FeS2 in the subshell,allowing ASZVI to reduce Cr(VI)efficiently and sustainably.In general,partial aging can enhance the reactive durability of ZVI when coupled with sulfidation and this synergistic effect will be beneficial to the application of SZVI-based technology for wastewater treatment.

Pancreatic cancer is one of the most lethal malignant tumors in the world.Despite advances in diagnosis and treatment,the five-year survival rate for pancreatic cancer patients remains only 9%.1 Pancreatic adenocarcinoma(PAAD)belongs to pancreatic cancer,which occupies 85%of the whole pancreatic cancer.2 Reversible modification of Ne-methyladenosine(mA)has been shown to be involved in cancer progression,resulting in up-regulation of oncogene expression or down-regulation of tumor-suppressing genes and may affect the prognosis of patients with pancreatic cancer.
