文摘BACKGROUND Liver cancer is a malignant tumor with high morbidity and mortality.Transcatheter arterial chemoembolization(TACE)is the main method for surgically unresectable liver cancer.In recent years,drug-loaded microspheres have been gradually applied in TACE technology.There are some controversies about the therapeutic effects of drug-loaded microspheres TACE(D-TACE)and traditional TACE.AIM To explore the short-term efficacy of D-TACE and traditional TACE in the treatment of advanced liver cancer.METHODS The clinical data of 73 patients with advanced liver cancer admitted to the First and Sixth Medical Centers of Chinese PLA General Hospital from January 2017 to October 2019 were retrospectively analyzed.Among them,15 patients were treated with D-TACE,and 58 patients were treated with traditional TACE.Clinical baseline characteristics,perioperative laboratory indices,postoperative adverse reactions and postoperative complications were compared between the two groups.RESULTS There was no statistical difference between the two groups for the postoperative response:The highest postoperative body temperature of the drug-loaded microsphere group was 38.0±0.9℃and the postoperative highest body temperature of the traditional TACE group was 38.3±0.7℃(t=-1.414,P=0.162).For the 24 h postoperative nausea and vomiting after surgery in terms of scoring and postoperative pain scores,the traditional TACE group was higher than the drugloaded microsphere group(χ2=14.33,P=0.014;χ2=32.967,P=0.000)and the two groups had significant statistical differences.The disease control rate at 3 mo after treatment in the drugloaded microsphere group was 60%and the disease control rate at 3 mo after treatment in the traditional TACE group was 75.9%(χ2=4.091,P=0.252).There was no statistical difference between the two groups of data.During the follow-up period,the number of interventional treatments received was once in the drug-loaded microsphere group and the traditional TACE group received an average of 1.48 treatments(χ2=10.444 P=0.005).There was a statistical difference between the two groups.CONCLUSION Compared with traditional TACE,D-TACE may have some advantages in the treatment of advanced hepatocellular carcinoma with a large tumor load in the short term,but the long-term clinical efficacy needs additional follow-up studies.In addition,compared with the traditional group,the patients in the drug-loaded microsphere group had better subjective tolerance and could reduce the number of interventional treatments.Therefore,D-TACE is worthy of clinical promotion.
文摘BACKGROUND Gastric cancer is a major global health issue,and the perioperative period critic-ally influences patient outcomes.The different effects of sevoflurane inhalation anesthesia and propofol total intravenous anesthesia on intraoperative stability,postoperative complications,and long-term oncologic outcomes in patients with gastric cancer undergoing radical gastrectomy remain unclear.AIM To compare the effects of sevoflurane inhalation anesthesia and propofol total in-travenous anesthesia on clinical outcomes,including intraoperative indicators,postoperative complications,adverse effects,pain scores,and survival.METHODS This single-center retrospective cohort study included 204 patients who underw-ent radical gastrectomy for gastric cancer from February 2019 to December 2022.Patients were assigned to either the sevoflurane group(n=103)or the propofol group(n=101)based on intraoperative anesthetic regimen.Standardized protoc-ols for anesthesia management,intraoperative monitoring,and postoperative analgesia were applied.Baseline characteristics;intraoperative metrics;adverse events;complications;Visual Analog Scale(VAS)scores at 2,4,6,24,and 48 hours;and survival outcomes were retrospectively collected.Group comparisons were performed usingχ2 for categorical variables,t test for continuous variables,RESULTS Baseline demographic and clinical characteristics were similar between groups.No significant differences were observed in intraoperative indicators or most 30-day postoperative outcomes,including length of stay,emergency department visits,and readmission rates.The propofol group showed elevated mean VAS pain score at 24 hours postoperatively,but no differences were found at other time points.The propofol group also had significantly higher postoperative nausea incidence and transiently higher systolic/diastolic blood pressure and heart rate at the time of incision than the sevoflurane group.No significant differences were seen in overall rates or severity of postoperative complications,intraoperative adverse events,or in overall survival and progression-free survival.CONCLUSION In patients undergoing radical gastrectomy for gastric cancer,sevoflurane and propofol anesthesia demonstrated similar profiles regarding intraoperative safety,postoperative complications,adverse events,postoperative pain,and long-term survival.The selection of anesthesia can be personalized without significantly affecting periop-erative or oncologic outcomes.

文摘Herein,3‑aminopropyltriethoxysilane(APTES)was used to modify F‑containing silica slag(SS)by simple grafting and served as a multifunctional barrier layer.The amino group(—NH2)in the amino‑modified SS(NH2‑SS)forms ligand bonds or hydrogen bonds with sulfur ions in lithium polysulfides(LiPSs),thus inhibiting the shuttle effect.Electrochemical analyses demonstrated that lithium‑sulfur(Li‑S)batteries employing the NH2‑SS interlayer exhibited discharge specific capacities of 1048 and 789 mAh·g^(-1) at 0.2C and 2C,respectively,and even at 4C,the initial discharge specific capacity remained at 590 mAh·g^(-1),outperforming the Li‑S battery with unmodified SS as the interlayer.

文摘The in-flight heating process of cerium dioxide(CeO_(2))powders was investigated through experiments and numerical simulations.In the experiment,CeO_(2)powder(average size of 30μm)was injected into radio-frequency(RF)argon plasma,and the temperatures were measured using a DPV-2000 monitor.A model combining the electromagnetism,thermal flow,and heat transfer characteristics of powder during in-flight heating in argon plasma was proposed.The melting processes of CeO_(2)powders of different diameters,with and without thermal resistance effect,were investigated.Results show that the heating process of CeO_(2)powder particles consists of three main stages,one of which is relevant to a dimensionless parameter known as the Biot number.When the Biot value≥0.1,thermal resistance increases significantly,especially for the larger powders.The predicted temperature of the particles at the outlet(1800–2880 K)is in good agreement with the experimental result.

文摘Agglomeration supports the high-quality development of the manufacturing industry,and its associated resource and environmental effects play a crucial role in driving green economic development.Based on data from prefecture-level cities in China from 2005 to 2019,this study employs the inverse distance weighting method,the bivariate local indicator of spatial association model,the spatial Durbin model,and other techniques to explore the relationship between manufacturing agglomeration and PM_(2.5)concentrations,and to assess the impact of its manufacturing agglomeration.Four correlation patterns are observed:high-high,low-low,high-low,and low-high.Among these,high-high and low-low patterns dominate in terms of number of cities.These correlation patterns demonstrate strong temporal stability,with a clear“Matthew effect”.The effect of manufacturing agglomeration on PM_(2.5)levels is significantly negative and helps reduce concentrations regionally,indicating the need to further enhance agglomeration levels regionally.However,it can increase PM_(2.5)levels in neighboring areas due to a siphon effect,and the impact of varies across regions.Compared with levels in 2005-2013,the significance of the relationship between manufacturing agglomeration and PM_(2.5)weakened in the 2013-2019 period.Accordingly,this study proposes countermeasures and policy recommendations aimed at strengthening regional collaborative governance and inspiring differentiated agglomeration strategies to support sustainable economic development in China.
文摘Chitosan(CTS)was grafted onto the surface of amino‑functionalized silver chloride silicon dioxide(AgCl@SiO_(2)‑NH_(2))cores to obtain AgCl@SiO_(2)/CTS hybrid nanoparticles.The as‑obtained AgCl@SiO_(2)/CTS nanoparticles were chlorinated by NaClO solution to get AgCl@SiO_(2)/CTS‑based chloramine nano‑hybrid materials,denoted as AgCl@SiO_(2)/CTS‑Cl.A transmission electron microscope was used to observe the morphology of the as‑prepared samples AgCl@SiO_(2)/CTS and AgCl@SiO_(2)/CTS‑Cl.At the same time,an X‑ray diffractometer and an infrared spectroscope were utilized to characterize their crystal and chemical structures.Besides,ζpotentials were measured to elucidate the surface modification of AgCl nanoparticles by—NH_(2),the antibacterial mechanism of AgCl@SiO_(2)/CTS‑Cl was investigated by scanning electron microscopy,and Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus)were used as the to‑be‑tested strains to evaluate the antimicrobial activity of samples AgCl@SiO_(2)/CTS and AgCl@SiO_(2)/CTS‑Cl.Findings demonstrate that sample AgCl@SiO_(2)/CTS exhibits a chain‑like structure ascribed to the interaction between—NH_(2),and each AgCl@SiO_(2)/CTS hybrid nanoparticle contains several AgCl cores.In the meantime,sample AgCl@SiO_(2)/CTS‑Cl exhibits excellent antibacterial activity against E.coli and S.aureus,which is attributed to the synergistic antibacterial effect of Ag^(+)and Cl^(-).Sample AgCl@SiO_(2)/CTS‑Cl with a dosage of 640.00μg·mL^(-1) could completely kill the two kinds of tested bacteria in 12 h of incubation;it retains a high antibacterial efficiency even after 10 cycles of antibacterial tests.

文摘The highly dynamic nature,strong uncertainty,and coupled multiple safety constraints inherent in carrier aircraft recovery operations pose severe challenges for real-time decision-making.Addressing bolter scenarios,this study proposes an intelligent decision-making framework based on a deep long short-term memory Q-network.This framework transforms the real-time sequencing for bolter recovery problem into a partially observable Markov decision process.It employs a stacked long shortterm memory network to accurately capture the long-range temporal dependencies of bolter event chains and fuel consumption.Furthermore,it integrates a prioritized experience replay training mechanism to construct a safe and adaptive scheduling system capable of millisecond-level real-time decision-making.Experimental demonstrates that,within large-scale mass recovery scenarios,the framework achieves zero safety violations in static environments and maintains a fuel safety violation rate below 10%in dynamic scenarios,with single-step decision times at the millisecond level.The model exhibits strong generalization capability,effectively responding to unforeseen emergent situations—such as multiple bolters and fuel emergencies—without requiring retraining.This provides robust support for efficient carrier-based aircraft recovery operations.

文摘Rechargeable Zn/Sn-air batteries have received considerable attention as promising energy storage devices.However,the electrochemical performance of these batteries is significantly constrained by the sluggish electrocatalytic reaction kinetics at the cathode.The integration of light energy into Zn/Sn-air batteries is a promising strategy for enhancing their performance.However,the photothermal and photoelectric effects generate heat in the battery under prolonged solar irradiation,leading to air cathode instability.This paper presents the first design and synthesis of Ni_(2)-1,5-diamino-4,8-dihydroxyanthraquinone(Ni_(2)DDA),an electronically conductiveπ-d conjugated metal-organic framework(MOF).Ni_(2)DDA exhibits both photoelectric and photothermal effects,with an optical band gap of~1.14 eV.Under illumination,Ni_(2)DDA achieves excellent oxygen evolution reaction performance(with an overpotential of 245 mV vs.reversible hydrogen electrode at 10 mA cm^(−2))and photothermal stability.These properties result from the synergy between the photoelectric and photothermal effects of Ni_(2)DDA.Upon integration into Zn/Sn-air batteries,Ni_(2)DDA ensures excellent cycling stability under light and exhibits remarkable performance in high-temperature environments up to 80℃.This study experimentally confirms the stable operation of photo-assisted Zn/Sn-air batteries under high-temperature conditions for the first time and provides novel insights into the application of electronically conductive MOFs in photoelectrocatalysis and photothermal catalysis.

文摘The efficient electrocatalytic oxidation of glycerol(GLY)is one of the most promising routes for the valorization of GLY.Doping has emerged as a powerful strategy to tailor the electrocatalytic performance of silver nanoclusters(Ag NCs),yet the effects of doping mode(surface vs.core)and the interface environment(e.g.,electrolyte concentration)on the electrocatalytic performance for Ag NCs toward GLY oxidation remain understood.In this work,surface-doped Ag_(4)M_(2)(SR)_(8) and core-doped Ag_(24)M(SR)_(18)(M=Ni,Pd,Pt;SR=SPhMe_(2))NCs were synthesized for electrocatalytic GLY oxidation.The results revealed a strong dependence of selectivity on doping mode and electrolyte concentration:under low KOH concentration,Pd-and Pt-doped Ag_(4)M_(2) NCs exhibited 100%selectivity toward oxalic acid(OA),whereas Pd-and Pt-doped Ag_(24)M NCs delivered>95%selectivity for formic acid(FA).In contrast,under high KOH concentration,Pd-and Pt-doped Ag_(4)M_(2) NCs gave rise to>80%FA,while Pd-and Pt-doped Ag_(24)M NCs produced>45%FA.Mechanism studies indicated that Ni doping predominantly enhanced catalytic activity via lowering the activation barrier of the initial reaction step(GLY→glyceraldehyde),whereas Pd and Pt doping modulated selectivity through reducing the energy barrier of the selective branch step(glyceric acid→OA,OA→FA).High KOH concentration promoted the oxidation by increasing the electrochemical active surface area and facilitating electron transfer of Ag NCs.This study provides clear guidance for designing high-performance Ag-based electrocatalysts for biomass valorization.

文摘The accuracy of photovoltaic(PV)power prediction is significantly influenced by meteorological and environmental factors.To enhance ultra-short-term forecasting precision,this paper proposes an interpretable feedback prediction method based on a parallel dual-stream Temporal Convolutional Network-Bidirectional Long Short-Term Memory(TCN-BiLSTM)architecture incorporating a spatiotemporal attention mechanism.Firstly,during data preprocessing,the optimal historical time window is determined through autocorrelation analysis while highly correlated features are selected as model inputs using Pearson correlation coefficients.Subsequently,a parallel dual-stream TCN-BiLSTM model is constructed where the TCN branch extracts localized transient features and the BiLSTM branch captures long-term periodic patterns,with spatiotemporal attention dynamically weighting spatiotemporal dependencies.Finally,Shapley Additive explanations(SHAP)additive analysis quantifies feature contribution rates and provides optimization feedback to the model.Validation using operational data from a PV power station in Northeast China demonstrates that compared to conventional deep learning models,the proposed method achieves a 17.6%reduction in root mean square error(RMSE),a 5.4%decrease in training time consumption,and a 4.78%improvement in continuous ranked probability score(CRPS),exhibiting significant advantages in both prediction accuracy and generalization capability.This approach enhances the application effectiveness of ultra-short-term PV power forecasting while simultaneously improving prediction accuracy and computational efficiency.

文摘Beam-tracking simulations have been extensively utilized in the study of collective beam instabilities in circular accelerators.Traditionally,many simulation codes have relied on central processing unit(CPU)-based methods,tracking on a single CPU core,or parallelizing the computation across multiple cores via the message passing interface(MPI).Although these approaches work well for single-bunch tracking,scaling them to multiple bunches significantly increases the computational load,which often necessitates the use of a dedicated multi-CPU cluster.To address this challenge,alternative methods leveraging General-Purpose computing on Graphics Processing Units(GPGPU)have been proposed,enabling tracking studies on a standalone desktop personal computer(PC).However,frequent CPU-GPU interactions,including data transfers and synchronization operations during tracking,can introduce communication overheads,potentially reducing the overall effectiveness of GPU-based computations.In this study,we propose a novel approach that eliminates this overhead by performing the entire tracking simulation process exclusively on the GPU,thereby enabling the simultaneous processing of all bunches and their macro-particles.Specifically,we introduce MBTRACK2-CUDA,a Compute Unified Device Architecture(CUDA)ported version of MBTRACK2,which facilitates efficient tracking of single-and multi-bunch collective effects by leveraging the full GPU-resident computation.
