It is well-known that some star clusters contain composite stellar populations(CSPs),in which the metallicities or(and)ages of stars are different.The formation and evolution of such clusters and their stellar populations remain unclear.Both single and binary cluster channels may lead to such CSPs.In order to simulate the formation and evolution of such CSPs in star clusters,this work develops a code of direct N-body simulation of CSPs,NbodyCP.It is applied to different clusters,in particular,to binary clusters.It shows that CSPs and different kinds of cluster pairs can be formed via dynamical processes.This will help to partially explain the formation of CSPs and various clusters.Some special cluster structures,e.g.,two cores or bar-like shape,are shown to be the results of evolution of some binary clusters.The simulation also shows that the separation between the members of a binary cluster affects the time of two member clusters to combine or move away significantly. 展开更多

Bottom-up and top-down endogenous automobile clusters exhibit distinct evolutionary traits and driving mechanisms,yet their comparative analysis remains understudied.Therefore,using Taizhou automobile industry cluster(TAIC)and Wuhu automobile industry cluster(WAIC)as cases,using historical statistical data and field interview data from the 1980s to 2023,combined with qualitative research methods of thematic and diachronic analysis,and quantitative research methods of social network analysis,we compare both endogenous automobile clusters’evolutionary traits and driving mechanisms.The results confirm both clusters undergo multi-scale spatial reconfiguration,organizational complexification,and intelligent networking technological transformation,yet diverge fundamentally:TAIC evolves through market-driven progressive expansion,transitioning from single to dual-core structures via private enterprise networking,with innovation following market-integrated logic and institutional thickness built on demand-driven evolution.Conversely,WAIC follows planned expansion,maintaining state-led hierarchical single-core stability through policy-driven breakthrough innovation and supply-dominated institutional construction-though both ultimately require formal-informal system synergy.Their coevolution is driven by dynamic interactions of path dependence(weakening influence),learning-innovation(strengthening influence),and relationship selection(inverted U-shaped trajectory),with divergent development paths rooted in TAIC’s grassroots self-organization genes versus WAIC’s top-level design genes,amplified by core enterprises’strategic disparities.The research findings can not only provide decision-making support for China’s industrial upgrading,but also contribute China’s insights to global economic governance. 展开更多

Gold nanoclusters(AuNCs)have garnered significant attention in biomedicine.Particularly,peptide-coupled AuNCs(PepAuNCs)are emerging as a fascinating class of cluster probes that enable highly tailorable design in their optical,catalytic,targeting,and therapeutic capabilities via peptide engineering.However,a comprehensive review dedicated to decoding the peptide-directed AuNC design and bioapplication paradigms is still lacking.This review systematically summarizes recent advances in the synthesis,probe design,and bioapplication of Pep-AuNCs from the perspective of peptide design.The strategies to couple AuNCs with peptides are first discussed,including in situ template synthesis and post-synthesis modification.Furthermore,we elucidate in detail how peptide sequence,structure,and coupling chemistry dictate the physicochemical and biological properties of AuNCs.We also summarize advanced functions such as specific targeting,stimuli-responsiveness,and therapeutics that can be rendered from the peptides for broadening the bioapplication potentials of AuNCs.Finally,we discuss the key challenges in their precise synthesis,long-term stability,and biotransformation study that must be addressed for clinical translation.By linking the peptide programming with the properties and application outcomes of AuNCs,this review aims to offer fundamental insights into the design principles of next-generation AuNC probes for diagnostic and therapeutic applications. 展开更多

Scarce investigations have focused on coinage metal clusters possessing fixed cores but varying binding ligands in the context of catalysis.Here in this work,we successfully employed two types of carboxylic acid-based molecular tweezers to selectively capture two Cu6clusters(Cu6-a and Cu6-b).Cu6-a and Cu6-b have identical cluster cores but different protected ligands,therefore provide accurate platform for investigating ligand effects in cluster catalysis.Notably,Cu6-b represents a rare example of a two-directional rod framework,marking the first instance of such a structure in coinage metal cluster-based MOFs.The integration of oxygen within OBB significantly enhances local spatial polarization,facilitating the charge separation and ROS generation efficiency of Cu6-b under visible-light irradiation.Consequently,the oxygen-containing Cu6-b exhibits superior photocatalytic performance in the aerobic oxidation of sulfide,achieving both high yield and selectivity.This work provides a valuable approach for precisely control the Cu clusters structures to regulate their properties. 展开更多

Euphorbiaceae species are renowned not only for horticultural significance but for their production of numerous bicyclic diterpenes with antitumor and antiviral activities.However,the gene clusters responsible for the biosynthesis of these terpenes remain largely unidentified.We here initiated the construction of a comprehensive procedure for terpene gene clusters in Euphorbiaceae species.A total of 1824 candidate gene clusters with the range of 30–800 kb were identified across seven representative species including Ricinus communis,Hevea brasiliensis,Euphorbia peplus,Jatropha curcas,Manihot esculenta,Vernicia montana,and Vernicia fordii in Euphorbiaceae.The 16 high-confidence terpene gene clusters were ultimately pinpointed in Euphorbiaceae after satisfied the three stringent screening criteria:TPS/CYP pairwise relationship,copathway and coexpression patterns.Notably,the well-known casbene and casbene-derived diterpenoid gene cluster,involved in the biosynthesis of casbene,neocembrene,ingenanes,and jatrophanes,were identified.It was observed that casbene gene clusters were universally presented in Euphorbiaceae species,except M.esculenta.Among the casbene gene cluster,the alcohol dehydrogenase(ADH)was initially appeared,and neocembrene synthase is exclusively present in R.communis while absent in all the other species.These findings represent a significant step toward understanding the genetic basis of terpene biosynthesis in Euphorbiaceae species.Moreover,this knowledge on gene clusters responsible for the biosynthesis of pharmacologically relevant terpenes can serve as a theoretical foundation for future applications. 展开更多

Based on the spectral data from the LAMOST Medium-Resolution Spectroscopic Survey(LAMOST-MRS)DR11-v1.1,combined with a publicly available open cluster catalog,we built a large-sample database of open clusters with medium-resolution spectroscopic parameters.This sample encompasses radial velocity measurements from medium-resolution spectroscopy for 1033 open clusters,among which 446 clusters further offer metallicity profiles and abundance distributions for dozens of chemical elements.Based on this comprehensive data set,we performed statistical analyses on key parameters of open clusters,including radial velocities,metallicities,and chemical element abundances.Notably,when the star cluster radial velocities are compared with results from the high-resolution spectroscopic survey,the mean difference is constrained within 1 km s−1,with a standard deviation less than 10 km s−1.For metallicity[Fe/H]comparisons with published highresolution literature values,the average discrepancy falls in the range of 0.02–0.04 dex,accompanied by a standard deviation of 0.06–0.08 dex.These findings demonstrate that open cluster properties derived by LAMOST-MRS exhibit reliable precision,making them suitable as probes for in-depth investigations into the chemical evolution of the Milky Way.Finally,we have compiled a catalog of 1033 open clusters,complemented by parameter lists for approximately 7000 member stars—all including their LAMOST-MRS spectroscopic parameters.This data set provides a valuable resource for advancing galactic astrophysics research. 展开更多

Specific anion exchange membranes(AEMs)are vital to highly efficient electrochemical CO2reduction(ECR),which is a promising choice for carbon neutrality.However,the unexpected trade-off effect originating from the ion conductivity and the hydrogen evolution reaction(HER)is still a great challenge.Herein,AEMs with hydrophobic clusters distribution in hydrophilic domain were designed and prepared by special ternary-polymerization polybenzimidazole(TP-PBI).The hydrophilic domain contributed to high ionic conductivity and dispersed hydrophobic clusters inhibited the membrane swelling and consequently the HER.As a result,an increase of 157%was achieved in ionic conductivity compared with that of OPBI and the prepared TP-PBI membranes exhibit CO Faradaic efficiency(FEco)as high as 96.2%,outstanding in situ durability for 24 h at 100 mA cm-2.Such TP-PBI membranes throw new light on the development of AEMs for highly efficient ECR. 展开更多

The high-precision Gaia Data Release 3(DR3)enables the discovery of numerous open clusters(OCs)in the Milky Way,providing an excellent opportunity to search for blue straggler stars in OCs and investigate their formation and evolution in these environments.Using the member stars from literature OC catalogs,we visually inspected the color-magnitude diagram(CMD)of each cluster and selected cluster candidates that potentially host blue stragglers.We then reassessed cluster memberships using the pyUPMASK algorithm with Gaia DR3 and performed isochrone fitting to derive physical parameters for each cluster,including age,distance modulus,mean reddening,and metallicity.Finally,we empirically identified straggler stars based on their positions relative to the best-fitting isochrone,zero-age main sequence,and equal-mass binary sequence on the CMD.In total,we identified 272 new straggler stars in 99 OCs,comprising 153 blue stragglers,98 probable blue stragglers,and 21 yellow stragglers.Compared to the reported blue straggler catalogs based on earlier Gaia data,our results increase the number of OCs with stragglers in the Milky Way by 22.2%,and the total number of blue stragglers by 11.2%. 展开更多

Large-scale offshore wind farm clusters(OWFCs)have been increasingly connected to the power grid,and requires advanced forecasting models to enhance the prediction accuracy of OWFC's power output.This paper proposes a multi-source fusion with patch-guided multi-task learning for power prediction of offshore wind farm clusters.Unlike traditional graph-based approaches that rely on predefined topological relationships,which are limited in capturing the highly similar but rapidly changing meteorological conditions among closely spaced offshore farms,the proposed model employs a parameter-sharing multi-task learning network to achieves both independence and correlation among offshore wind farm clusters,followed by utilizing a dynamically weighted multi-task loss function to gradually optimize the network parameters.Moreover,the proposed model applies the patch-guided feature learning module further enables natural alignment and fusion of multi-source data.To demonstrate the performance of the proposed model,experiments were conducted on offshore wind farm clusters in three different regions.The results show that the proposed model can obtain an average accuracy improvement of around 24.31%for MAE and 19.l4%for RMSE,ensuring prediction accuracy and robustness. 展开更多

Metal oxide semiconductor-supported noble metal nanoparticles are common sensing materials for gas sensors.However,the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability.Herein,a salt-assistant strategy is developed to prepare fully-exposed Ir clusters on SnO2 nanorods,enabling highly sensitive and stable H2sensing.By introducing potassium nitrate as a precursor,it was found that the nitrate can induce the Ir species to be exposed on the SnO2 surface in the form of highly-distributed nanoclusters with an average size of less than 1 nm.Meanwhile,the strong interaction between SnO2 and Ir clusters ensures the durability of the catalysts under elevated temperatures(300℃).The final Clu-Ir/SnO2 sensors exhibit excellent H2 sensing performance,featuring a high response value(46@4000 ppm H2),fast responseecovery time(4.6/3.7 s@4000 ppm H2),and a low detection limit(as low as 1 ppm).Notably,no significant change in the dispersion state of the Ir metal is observed even after 60 days of continuous use,demonstrating excellent long-term stability.In situ Raman,ex situ X-ray photoelectron spectroscopy(XPS),and H2-temperature-programmed reduction(TPR) results prove that the sensitization mechanism of fully dispersed and exposed Ir clusters involves oxygen capture and activation,H2adsorption and conversion to H species,and optimization of electron transfer pathways to SnO2.Overall,this study provides valuable insights into the synthesis of fully exposed cluster catalysts capable of stable operation under high temperatures in gas sensing applications. 展开更多

Near-infrared(NIR)light offers significant advantages in photocatalytic reactions due to its excellent penetration ability and low phototoxicity.However,the development and utilization of NIR light for efficient photocatalysis continue to encounter several challenges.In this work,we designed and synthesized two stable iron-oxo clusters functionalized with 1,1-ferrocene dicarboxylic acid(Fcdc),Fe11-Fcdc and BiFe10-Fcdc,both of which can effectively utilize full-spectrum light to realize efficient oxidative coupling reaction of benzylamine(BA)with a product of selectivity over 90% and a conversion up to 97%.Particularly,under the NIR light,Fe11-Fcdc shows significantly better photocatalytic performance(a conversion of 82.3%)than BiFe10-Fcdc(41.0%),which may be responsible for the stronger metal-ligand charge transfer effect in Fe11-Fcdc.This work reports for the first time the study of ferrocene-modified crystalline clusters achieving effective utilization of NIR light. 展开更多

The electrocatalytic two-electron oxygen reduction reaction(2e–ORR)offers an environmentally friendly method for hydrogen peroxide(H2O2)production,yet the development of efficient and cost-effective electrocatalysts remains a significant challenge.Herein,we have synthesized Ni3N2clusters anchored on N-doped carbon nanostructures(Ni3N2/NC)through a straightforward biomass-derived modification-pyrolysis method for efficient H2O2production.Theoretical calculations reveal that the D-band center of Ni sites in Ni3N2/NC shows a downshift and successive state,which is beneficial to the formation of key*OOH intermediates and occurrence of subsequent reactions.Remarkably,Ni3N2/NC achieves a 2e–ORR selectivity of 91.65%and an onset potential of 0.69 V.When tested in a practical flow cell,Ni3N2/NC exhibits a Faradaic efficiency(FE)of 91.42%and attains a maximum H2O2yield of 3.26 mol gcat−1h−1at 100 mA/cm2.Additionally,the FE remains above 85%during a 12 h constant current stability test at 40 mA/cm2,highlighting its potential for sustainable H2O2production. 展开更多

Developing an irradiation embrittlement predictive model for low-Cu reactor pressure vessel steels is essential for extending the life of modern pressurized water reactors.Irradiation-produced dislocation loops are recognized as the leading causes of embrittlement,surpassing the mechanism of Cu clustering with a reduction in Cu content in modern steels.Extensive data have been accumulated from surveillance programs on high-Cu steels used in old reactors.The extrapolation of these data to low-Cu systems for embrittlement prediction requires a comprehensive understanding of the interactions between Cu,particularly Cu-rich clusters,and radiation defects.Therefore,in this study,ab initio calculations of vacancy aggregation in solute clusters containing Cu,Ni,Mn,and Si were performed.The interactions between the solute elements and vacancies in the solute clusters and Fe matrix were analyzed.The results demonstrated the occurrence of attractive interactions between the Cu clusters and vacancies.The addition of Si and the synergistic effect between Ni and Mn facilitated vacancy aggregation in the solute clusters.The behavior of Mn correlated with its magnetic state,and the size effects of the solute elements were analyzed. 展开更多

Introduction:Chemotherapy-induced gastrointestinal symptom clusters in breast cancer impair quality of life and treatment adherence,yet lack effective interventions.While acupuncture mitigates isolated chemotherapy-induced symptoms,its mechanisms for multi-symptom clusters remain unclear.This study evaluates electroacupuncture's efficacy and explores its biological mechanisms in managing these clusters.Methods:This prospective,multicenter,block-randomized,double-blind,sham-controlled trial will enroll 388 patients with breast cancer undergoing neoadjuvant/adjuvant chemotherapy,to be randomly assigned(1:1)to electroacupuncture or sham electro-acupuncture groups.Both groups will receive the standard quadruple antiemetic regimen combined with electroacupuncture or sham intervention.The primary endpoint is the incidence of chemotherapy-induced gastrointestinal symptom clusters within 120 h after chemotherapy.Secondary endpoints include improvement in gastrointestinal symptom clusters post-first chemotherapy cycle,nausea-free rates during acute and delayed phases,vomiting-free rates during overall,acute,and delayed phases,complete response rate,complete protection rate,and quality of life.Adverse events will be documented throughout the study.Discussion:This study will assess the efficacy and safety of electroacupuncture in alleviating chemotherapy-induced gastro-intestinal symptom clusters in patients with breast cancer.By integrating multi-omics analyses,we aim to elucidate the biological mechanisms underlying its therapeutic effects.The findings may offer a robust clinical foundation for optimizing symptom cluster management in cancer care.Trial Registration:Clinical Trials ID:NCT06952920.Date of registration:April 16,2025.Prospectively registered.URL of Trial Registry Record:http://gffzzd3f38a9638994581snvnq6bnn0ubk6kqb.ffgz.tsg.suse.edu.cn/study/NCT06952920cond=NCT06952920&rank=1. 展开更多

We present a comprehensive analysis of four young open clusters,NGC 663,NGC 2301,NGC 2384,and NGC 7510,utilizing high-precision astrometric and photometric data from Gaia DR3.Cluster membership was determined using the UPMASK algorithm,resulting in probable member counts ranging from 337 to 1498 across the clusters.Bayesian Markov Chain Monte Carlo isochrone fitting yielded cluster ages in the range logt 7.0-8.15,with uncertainties of∼0.11-0.18.Reddening values ranged from E(B-V)=0.093 mag in NGC 2301 to 1.24 mag in NGC 7510,consistent with their positions near the Galactic plane.The stellar mass function slopes(α≈2.00-2.26)closely match the Salpeter IMF,with total stellar masses spanning nearly an order of magnitude,from∼486 M⊙in NGC2301 to∼3584 M⊙in NGC 663.Dynamical relaxation times indicate that only NGC 2301(τ≈10.00)and NGC2384b(τ≈2.03)are dynamically relaxed;the others remain dynamically evolving.Orbital integrations in the MWPotential2014 model reveal nearly circular Galactic orbits with very low eccentricities(e≈0.003-0.014)and small vertical distances(Zmax<0.142 kpc),confirming their confinement to the thin disk.SED and kinematic analyses show that NGC 2384a&b are separated by∼0.55 kpc,indicating an optical pair. 展开更多

We perform Bayesian targeted searches for continuous gravitational waves from eccentric supermassive binary black holes(SMBBHs)using the Parkes Pulsar Timing Array third data release(PPTA DR3).Six electromagnetically motivated sky directions are analyzed,including the blazar OJ 287 and five nearby galaxy clusters(Virgo,Fornax,Norma,Hercules,and Coma).No significant signals are found.For OJ 287,by explicitly incorporating orbital eccentricity(up to e0=0.8)to robustly capture signal power spread across multiple harmonics,we constrain the total binary mass to Mtot<5.25×1010M⊙(95%credible level).We also place upper limits on the chirp mass of potential SMBBHs residing in galaxy clusters.By combining these limits with independent black hole mass estimates,we place novel constraints on the allowed binary mass ratios for potential hosts such as M87 and NGC 4889.Specifically,our results exclude binaries with mass ratios q■10-2at around 10 n Hz for these massive systems,effectively ruling out equal-mass black hole mergers in the sampled parameter space.These findings demonstrate the growing power of pulsar timing arrays to probe SMBBH populations. 展开更多

With the deepening of the power system reform,an increasing number of microgrids are being integrated into the distribution network.In traditional centralized optimization algorithms,the optimal power flow model of the distribution network and the optimal scheduling model of microgrid clusters are directly coupled and solved simultaneously.This process involves extensive information exchange between the upper distribution network system and the lower microgrid clusters,which not only increases the communication burden but also prolongs computation time and raises computational complexity.Moreover,it requires excessive information sharing,making it difficult to achieve limited information exchange between the upper and lower systems.In this paper,an optimization model and solution method based on the analytical target cascading approach are proposed.First,a typical microgrid model is constructed.On this basis,a collaborative optimization model for the active distribution network(ADN)and microgrid clusters is established.The distribution network and the microgrid clusters are treated as a unified entity of interest,with their interconnection power represented as virtual generators and virtual loads to achieve decoupling.Finally,simulations based on the IEEE-33 node standard system are conducted.Compared with the centralized algorithm,the effectiveness of the analytical target cascading method in coordinating the distribution network and microgrid clusters is verified.The proposed approach reduces computational complexity and enables optimized operation with limited information exchange. 展开更多

Metal sulfide-bridged clusters exhibit unique topologies and functional properties,offering potential for advanced materials and biomimetic systems.However,challenges persist in their controlled synthesis,particularly in precise sulfide incorporation and structural modulation to form high-nuclearity clusters.Herein,we report an in situ molecular tailoring strategy using protonation of the[Tp*WS3]-synthon by NH4+to gradually release S2-ions,which react with in situ formed fragments such as[Tp*WS3Cu3]2+and[Tp*WS3Cu2]+.Under the cooperative influence of Cl-,CN-,or Cu+,three low-nuclearity clusters with complex polyhedral structures are assembled.Solvent-induced post-scissoring and reassembly of these precursors afford two unprecedented high-nuclearity clusters with novel topological frameworks.Thin films derived from single crystals of all five clusters display significantly enhanced third-order nonlinear optical(NLO)responses compared to their solution-state counterparts.Importantly,the high-nuclearity clusters display NLO responses,surpassing not only those of their precursors but also the additive contributions of the individual units.Density functional theory(DFT)calculations attribute this enhancement to improved intracluster charge separation and synergistic interactions via linkers.This work establishes a versatile platform for constructing high-nuclearity metal sulfide clusters and provides new insights into designing functional analogues of nitrogenase-active sites. 展开更多

We study Onsager vortex clustered states in a shell-shaped superfluid containing a large number of quantum vortices.In the incompressible limit and at low temperatures,the relevant problem can be boiled down to the statistical mechanics of neutral point vortices confined on a sphere.We analyze rotation-free vortex-clustered states within the mean-field theory in the microcanonical ensemble.We find that the sandwich state,which involves the separating of vortices with opposite circulation and the clustering of vortices with the same circulation around the poles and the equator,is the maximum entropy vortex distribution,subject to a zero angular momentum constraint.The dipole moment vanishes for the sandwich state and the quadrupole tensor serves as an order parameter to characterize the vortex cluster structure.For a given finite angular momentum,the equilibrium vortex distribution forms a dipole structure,i.e.,vortices with opposite sign are separated and accumulate around the south and north poles,respectively.The conditions for the onset of clustering and the exponents associated with the quadrupole moment and the dipole moment as functions of energy are obtained within the mean field theory.At large energies,we obtain asymptotically exact vortex density distributions using the stereographic projection method,yielding the parameter bounds for the vortex clustered states.The analytical predictions are in excellent agreement with microcanonical Monte Carlo simulations. 展开更多
