The increasing demand for flexible displays and wearable electronics has driven extensive efforts to develop stretchable organic lightemitting diodes(OLEDs).A critical challenge in this field is the creation of emissive layers that combine high efficiency with mechanical robustness.Thermally activated delayed fluorescence(TADF)materials have attracted significant attention as third-generation emitters capable of achieving 100%internal quantum efficiency;however,their application in stretchable OLEDs has been limited.In this study,we propose an elastomer doping strategy.Polyurethane(PU)is incorporated into TADF polymers to improve their mechanical flexibility while maintaining a high luminescent efficiency.The resulting composite films exhibited excellent TADF characteristics and remarkable stretchability(75%).OLEDs fabricated from these materials achieved a maximum external quantum efficiency(EQE)of 14.26%and a peak luminance of 73570 cd·m-2,with the PUdoped devices showing a significantly suppressed efficiency roll-off.Additionally,a fully stretchable OLED architecture was designed and operated under tensile strain to maintain stable electroluminescent performance.These results demonstrate that elastomer doping is an effective strategy for balancing the mechanical compliance with optoelectronic performance,offering a promising pathway for the development of high-performance stretchable OLEDs for flexible electronics. 展开更多

To tackle the physical layer security challenges in wireless communication,this paper introduces a multiuser architecture that leverages single-channel blind source separation,centered around a Multi-source Signal Mixture Separator(MSMS).This architecture consists of a multi-user encoder,a channel layer,and a separation decoder,allowing it to handle multiple functions simultaneously,including encoding,modulation,signal separation,demodulation,and decoding.The MSMS receiver effectively enables the separation of numerous user signals,making it exceedingly difficult for unauthorized eavesdroppers to extract valuable information from the mixed signals,thus significantly enhancing communication security.The MSMS can address the challenges of few-shot sample training and achieve joint optimization during transmission by employing a deep learning-based network design.The design of a single receiver reduces system costs and improves spectrum efficiency.The MSMS outperforms traditional Space-time Block Coding(STBC)strategies regarding separation performance,particularly in Block Error Rate(BLER)metrics.Modulation constellation diagrams further analyze the effectiveness of multi-source signal mixture separation.Moreover,this study extends the MSMS framework from a two-user scenario to a three-user scenario,further demonstrating the flexibility and scalability of the proposed architecture. 展开更多

Solid polymer electrolytes(SPEs)offered enhanced safety and superior lithium dendrite suppression compared to liquid electrolytes,yet suffered from inadequate ionic conductivity and poor interfacial stability.Phase-separated polymer electrolytes(PSPEs)partially addressed these limitations but introduced dual-interface challenges,including insufficient electrode contact and inhomogeneous phase distribution.This work presented a novel BSF composite electrolyte fabricated through in situ polymerization of a PSPEs system comprising butyl acrylate(BA),succinonitrile(SN),and LiTFSI,with fluoroethylene carbonate(FEC)as a critical additive.This design simultaneously enhanced the compatibility between the polymerized BA matrix and the SN liquid phase,established continuous ion transport pathways,improved interfacial wettability,and generated stable LiF-rich interphases at both electrodes.The structural evolution and interfacial chemistry were systematically verified through Raman mapping,HAADFSTEM,and TOF-SIMS analyses.Electrochemical evaluation demonstrated exceptional performance.The constructed Li|BSF|Li symmetric cells achieved stable cycling for over 2000 h at 0.5 mA/cm2with a critical current density(CCD)of 4.2 m A/cm2.Moreover,Li|BSF|NCM811 full cells with a high mass loading(18 mg/cm2)retained 80.5%of their capacity after 100 cycles.These results represented state-of-theart performance among polymer-based solid electrolytes,underscoring the potential of the BSF system for high-energy-density lithium metal batteries. 展开更多

The genus Pachytriton is distributed in eastern and southern China,with its taxonomic diversity significantly expanded through advances in molecular systematics.To investigate the distribution and evolutionary history of Pachytriton feii,this study surveyed the Huangshan-Huaiyu Mountains Biodiversity Conservation Priority Area from April to May 2025.Based on detailed morphological measurements and phylogenetic analyses of two mitochondrial genes(Cytb and ND2)and the nuclear gene RAG1,one undescribed species(later formally named Pachytriton yeae sp.nov.)was discovered and formally described.Phylogenetically,the new species forms a strongly supported independent clade(maximum likelihood,ML=99%;Bayesian posterior probability,BPP=0.99)as the sister group to P.feii,with uncorrected genetic distances of 5.5%(Cytb)and 7.1%(ND2)—both exceeding the generally recognized species-level genetic threshold for amphibians.Morphologically,the new species differs from P.feii by the presence of a distinctive silver tail stripe(absent in P.feii),as well as larger head width(HW),head length(HL),chest width(CW),and tail height(TH)in both sexes.It also exhibits sex-specific traits:males have longer forelimbs(FL)and a wider internasal distance(IND),while females have longer tails(TL).This new species raises the known species count of Pachytriton to eleven,confirming that the biodiversity of the subtropical mountains of eastern China was underestimated.Given its restricted distribution and threats from deforestation and hydropower development,urgent conservation prioritization in the Huaiyu Mountains is needed to protect the new taxon and co-occurring endemic amphibians. 展开更多

The safety of high-energy–density battery packs remains a critical challenge for electric vehicles.Thermal runaway in a single cell releases substantial thermal energy,which can trigger propagation and induce structural damage within the pack.Conventional strategies relying solely on passive insulation are increasingly inadequate for mitigating such severe thermal loads.To address this,we propose and experimentally validate a battery pack design featuring a large-face liquid cooling structure.This architecture integrates four safety functions-thermal insulation,electrical isolation,large-face liquid cooling,and directional venting-into a cohesive defense-in-depth strategy.Two thermal runaway experiments demonstrated the suppression of propagation.The dual-layer upper cover withstood high-temperature jet impingement and maintained the pack's structural integrity.To elucidate the underlying mechanisms,we developed a fluid–structure interaction model.The model revealed the heat transfer pathways associated with large-face liquid cooling.When coolant circulation was activated,88.6%to 90.0% of the heat was prevented from transferring to adjacent cells.Even when circulation was disabled,54.4%to 55.4%of the heat was still impeded.Furthermore,under high-temperature jet impingement,local stress on the upper cover was governed initially by pressure and subsequently by temperature,indicating that cover protection must balance structural strength and thermal insulation.This work provides practical guidelines for current and future battery pack designs. 展开更多

In this study,we aimed to investigate the influence of paternal oligozoospermia(OZ),asthenozoospermia(AZ),or teratozoospermia(TZ)on blastocyst ploidy and its potential interaction with maternal age.We analyzed 3383 embryos in 1091 preimplantation genetic testing for aneuploidy(PGT-A)cycles via next-generation sequencing(NGS)at the Center for Reproductive Medicine,Shandong University(Jinan,China).Our findings revealed that compared to the normozoospermic(NZ)group,the AZ group exhibited significantly lower euploidy rates(P=0.022).This effect was more pronounced in cases with advanced maternal age(AMA;≥38 years),where AZ patients had markedly reduced euploidy rates(P=0.003),while no significant differences were observed in younger women(<38 years).Multivariate analysis,adjusting for parental age and body mass index(BMI),confirmed that AZ is an independent risk factor for reduced euploidy rates in the AMA subgroup.Notably,OZ and TZ cases showed no significant association with blastocyst ploidy rates.These results suggest that only in cases of advanced maternal age,impaired sperm motility adversely affect blastocyst euploidy rates. 展开更多

Body surface temperature(Tb)is a key determinant of physiological performance,behavior,and fitness in ectotherms,and its dynamic variation provides critical insights into thermal adaptation.However,field-based data on Tb and its relationship with microhabitat temperature(Te)remain scarce for amphibians and reptiles inhabiting extreme arid desert ecosystems in China.While considerable related research has been conducted in desert regions of Africa,the United States,and Australia,the unique climatic and ecological characteristics of Chinese deserts highlight the urgent need for regional thermal ecology data to fill this knowledge gap.Using infrared thermal imaging,a non-invasive approach to temperature measurement,we quantified Tb(Tb-h,head surface temperature;Tb-d,dorsal surface temperature)and Te in two amphibian and four reptile species from the Tarim River Basin to investigate their thermoregulatory strategies under extreme desert conditions.Our results revealed substantial interspecific variation in Tb.Reptiles generally exhibited higher Tb than amphibians,with the highest species-level mean exceeding 40°C.Within species,significant differences between Tb-h and Tb-d were detected in both amphibians and reptiles,indicating heterogeneous thermal demands among body regions;however,the patterns of these differences were species specific.With respect to TbTe relationships,most species showed strong positive correlations between Tb and Te,with the notable exception of Bufotes pewzowi.This species exhibited basking behavior and appeared capable of exploiting thermal gradients to maintain distinct thermal patterns during daytime compared with nighttime.Collectively,these findings highlight the diversity of Tb patterns among desert ectotherms and underscore the importance of integrating behavioral,physiological,and environmental data to better understand their ecological adaptations and vulnerability to climate change.Our study further demonstrates the utility of infrared thermal imaging as a real-time,non-invasive tool for assessing ectotherm thermal ecology in the field. 展开更多

Direct converting carbon dioxide(CO2)and propane(C3H8)into aromatics with high carbon utilization offers a desirable opportunity to simultaneously mitigate CO2emission and adequately utilize C3H8 in shale gas.Owing to their thermodynamic resistance,converting CO2and C3H8 respectively remains difficult.Here,we achieve 60.2%aromatics selectivity and 48.8%propane conversion over H-ZSM-5-25 via a zeolite-catalyzing the coupling of CO2and C3H8.Operando dual-beam FTIR spectroscopy combined with 13C-labeled CO2tracing experiments revealed that CO2is directly involved in the generation of aromatics,with its carbon atoms selectively embedded into the aromatic ring,bypassing the reverse water-gas shift pathway.Accordingly,a cooperative aromatization mechanism is proposed.Thereinto,lactones,produced from CO2and olefins,are proven to be the key intermediate.This work not only provides an opportunity for simultaneous conversion of CO2and C3H8,but also expends coupling strategy designing of CO2and alkanes over acidic zeolites. 展开更多

Pear fruit corking disorder is a non-infectious physiological condition that primarily occurs during the late developmental stages of pear and significantly impacts fruit quality and economic value in several major cultivars.As the underlying mechanism remains unclear,effective prevention strategies and genetic improvements continue to present major challenges.In this study,‘Akizuki’pear was used as experimental material,and the lignin content in cork-affected tissue was found to be significantly higher than in healthy tissue.Exogenous abscisic acid(ABA)treatment induced cork formation and promoted lignin biosynthesis,a major structural component,in both pear fruits and calli.Through integrated RNA-seq and expression analyses,we identified the ABA-responsive gene PbrMYB8,which was differentially expressed between healthy and diseased tissues and associated with lignin biosynthesis during corking disorder.Stable transformation of PbrMYB8 into pear calli and Arabidopsis confirmed its role in promoting lignin biosynthesis.Notably,PbrMYB8 not only activated lignin biosynthesis genes independently but also interacted with PbrMYB169 to form a protein complex that co-regulated their expression.These findings improve our understanding of lignin biosynthesis in pear fruit corking disorder by identifying a key regulator and its interaction network and provide a theoretical foundation for future strategies aimed at improving pear fruit quality. 展开更多

BACKGROUND Postoperative intestinal paralysis is common in gastrointestinal surgery,and the study of electroacupuncture mechanisms is of great significance.AIM To explore the neuroimmune regulatory mechanism of electroacupuncture at the Zusanli acupoint(ST36)in postoperative intestinal paralysis following gastrointestinal surgery.METHODS A total of 156 patients admitted to the Affiliated Hospital of Jiangnan University between January 2022 and October 2024 for postoperative intestinal paralysis following gastrointestinal surgery were randomly divided into two groups:A control group and an electroacupuncture group,with 75 patients in each.The control group received conventional Western medical treatment,while the electroacupuncture group received electroacupuncture in addition to this,at the bilateral Zusanli acupoints.Both groups received treatment for 7 days.Clinical efficacy,gastrointestinal function recovery,and gastrointestinal hormone[motilin(MTL),gastrin(GAS)],neurotransmitter[vasoactive intestinal peptide(VIP),nitric oxide(NO)],and inflammatory cytokine[tumor necrosis factor-α(TNF-α),serum interleukin-6(IL-6),interleukin-1β(IL-1β)]levels were compared between the two groups before and seven days after treatment.Adverse reactions were also recorded.RESULTS The electroacupuncture group demonstrated a higher overall treatment effectiveness rate and faster recovery of bowel sounds,as well as faster first defecation and first flatus than the control group(P<0.05).After seven days of treatment,MTL and GAS levels were significantly higher and VIP,NO,TNF-α,IL-6 and IL-1βlevels were significantly lower in the electroacupuncture group than in the control group(P<0.05).No adverse reactions were observed in either group during treatment.CONCLUSION Electroacupuncture at the Zusanli acupoint can enhance clinical efficacy,promote the recovery of gastrointestinal function,and regulate the neuroimmune microenvironment in patients with intestinal paralysis after gastrointestinal surgery.This mechanism may involve excitation of the vagus nerve and activation of the cholinergic antiinflammatory pathway through electroacupuncture stimulation of the Zusanli acupoint. 展开更多

Enamel demineralization often occurs in the early stage of dental caries.Studying the microscopic mechanism of enamel demineralization is essential to prevent and treat dental caries.Terahertz(THz)technolo⁃gy,especially continuous wave(CW)THz near-field scanning microscopy(THz-SNOM)with its nanoscale reso⁃lution,can be promising in biomedical imaging.In addition,compared with traditional THz time-domain spec⁃troscopy(TDS),portable solid-state source as the emission has higher power and SNR,lower cost,and can ob⁃tain more precise imaging.In this study,we employ CW THz-SNOM to further break the resolution limitations of conventional THz imaging techniques and successfully achieve the near-field imaging of demineralized enamel at the nanoscale.We keenly observe that the near-field signal of the enamel significantly lowers as demineralization deepens,mainly due to the decrease in permittivity.This new approach offers valuable insights into the micro⁃scopic processes of enamel demineralization,laying the foundation for further research and treatment. 展开更多

COMPERA 2.0 risk stratification has been demonstrated to be useful in patients with precapillary pulmonary hypertension(PH).However,its suitability for patients at risk for post-capillary PH or PH associated with left heart disease(PH-LHD)is unclear.To investigate the use of COMPERA 2.0 in patients with severe aortic stenosis(SAS)undergoing transcatheter aortic valve replacement(TAVR),who are at risk for post-capillary PH,a total of 327 eligible SAS patients undergoing TAVR at our institution between September 2015 and November 2020 were included in the study.Patients were classified into four strata before and after TAVR using the COMPERA 2.0 risk score.The primary endpoint was all-cause mortality.Survival analysis was performed using Kaplan-Meier curves,log-rank test,and Cox proportional hazards regression model.The study cohort had a median(interquartile range)age of 76(70–80)years and a pulmonary arterial systolic pressure of 33(27–43)mmHg(1 mmHg=0.133 kPa)before TAVR.The overall mortality was 11.9%during 26(15–47)months of follow-up.Before TAVR,cumulative mortality was higher with an increase in the risk stratum level(log-rank,both P<0.001);each increase in the risk stratum level resulted in an increased risk of death(hazard ratio(HR)2.53,95%confidential interval(CI)1.54–4.18,P<0.001),which was independent of age,sex,estimated glomerular filtration rate(eGFR),hemoglobin,albumin,and valve type(HR 1.76,95%CI 1.01–3.07,P=0.047).Similar results were observed at 30 d after TAVR.COMPERA 2.0 can serve as a useful tool for risk stratification in patients with SAS undergoing TAVR,indicating its potential application in the management of PH-LHD.Further validation is needed in patients with confirmed post-capillary PH by right heart catheterization. 展开更多

Two cross⁃sectional configurations of thin⁃walled square tubes partially filled with lightweight metallic foams are proposed,and termed as double⁃cell configuration partially filled with foam(DC⁃PF)and double⁃tube configuration partially filled with foam(DT⁃PF),respectively.The bending crashworthiness is investigated based on three⁃point bending tests using finite element ABAQUS/Explicit code.The two key mechanical indicators including Crash Load Efficiency(CLE)and Specific Energy Absorption(SEA)are introduced to evaluate the effect of foams in comparison with empty square tubes and fully filled square tubes.The numerical results show that the two partially filled configurations,especially DT⁃PF,display dramatically excellent bending crashworthiness compared with empty and fully filled square tubes.There exists a foam density threshold,beyond which the CLE of DT⁃PF achieves a maximum constant.In addition,there seems to be another foam density threshold,beyond which the SEA of DT⁃PF gets to the maximum value.It is also shown that the foam density threshold corresponding to the maximum SEA varies with the thickness of thin⁃walled square tubes. 展开更多

Roadkill has become a pivotal issue in the global decline of amphibian populations.Conventional research methods have typically relied on the examination of dried carcasses found long after wildlife-vehicle collisions, which influnce the accuracy of the taxonomic classification and assessment of roadkill rates. To overcome these limitations, we conducted a nocturnal survey on National Road G108in the Qinling Mountains immediately following a night rainstorm in July 2016. We employed molecular techniques to distinguish species that are morphologically identical but share overlapping habitats. Our investigation revealed that within five hours, 92 amphibians from five different species were documented across three 2-km road transects. Among these, 31 individuals were identified as roadkill,resulting in an overall rate of 33%, or roughly five fatalities per kilometer. Significantly, the mountain stream frogs Nanorana quadranus and N. taihangnica comprised 40.2% and 30.4% of the total individuals observed, with mortality rates of 35.1% and 25.0%,respectively. We found no significant variation in mortality rates between different age groups or genders for either species. Our research suggests that conducting surveys at night, immediately following summer rainstorms, is an efficient strategy for evaluating the impacts of roadkill. The post-rain foraging behaviors and the dispersal of juveniles are key factors contributing to road crossings outside of the breeding season. Consequently, this study recommends that traffic authorities in mountainous areas take measures to reduce vehicle traffic following summer rainstorms in order to minimize the threat to amphibian lives. 展开更多

We present the application of a machine learning based galaxy group finder to real observational data from the Sloan Digital Sky Survey Data Release 13(SDSS DR13).Originally designed and validated using simulated galaxy surveys in redshift space,our method utilizes deep neural networks to recognize galaxy groups and assess their respective halo masses.The model comprises three components:a central galaxy identifier,a group mass estimator,and an iterative group finder.Using mock catalogs from the Millennium Simulation,our model attains above 90%completeness and purity for groups covering a wide range of halo masses from~1011to~1015h-1Me.When applied to SDSS DR13,it successfully identifies over 420,000 galaxy groups,displaying a strong agreement in group abundance,redshift distribution,and halo mass distribution with conventional techniques.The precision in identifying member galaxies is also notably high,with more than 80%of groups with lower mass achieving perfect alignments.The model shows strong performance across different magnitude thresholds,making retraining unnecessary.These results confirm the efficiency and adaptability of our methodology,offering a scalable and accurate solution for upcoming large-scale galaxy surveys and studies of cosmological formations.Our SDSS group catalog and the essential observable properties of galaxies are available at http://gffzz188fe103f8f1460as6fn5uw5qunnf6pvw.ffgz.tsg.suse.edu.cn/Juntao Ma/SDSS-DR13-group-catalog.git. 展开更多

Hypersonic flow over a canonical 25°−55°double-cone configuration with a freestream Mach number of 10.38 is numerically investigated.In contrast to a relatively stable and moderate separation region in experiments,axisymmetric calculations in the literature demonstrated that the separation bubble continuously grew and notably exceeded the experimental result.To explain the causes of the discrepancy,time-accurate axisymmetric and Three-Dimensional(3D)simulations are conducted for the double-cone flow to investigate the evolution of three-dimensionality and unsteadiness.Both the axisymmetric calculation and the 3D simulation without external disturbances predict a significantly larger separation region than that in experiments and misrepresent the distributions of surface pressure and heat flux.The random forcing approach with two levels of noise amplitude is then applied to 3D simulations.A better agreement with the measured data is observed for the time-averaged heat flux and pressure when the white noise is enforced.As the forcing amplitude is increased,the agreement is slightly improved.However,discrepancies between the 3D results and experimental data still exist in the prediction of the heat flux and pressure distributions,indicating the essential difference between the injected white noise and the wind tunnel freestream disturbances.Realistic noise models are required to reveal the sources of such discrepancies. 展开更多

Dear Editor,Tadpoles play vital roles in many aquatic ecosystems and show considerable morphological diversity(Altig and Mc Diarmid,1999).Understanding the morphology and ecology of these larval stages is therefore essential for comprehending the ecological requirements of specific anuran species(Inger,1985;Dubois,2010).The Xizang Autonomous Region is home to highly diverse amphibian communities,with more than 58 species identified to date(Che et al.,2020). 展开更多
