Oxide dispersion strengthened(ODS)alloys are extensively used owing to high thermostability and creep strength contributed from uniformly dispersed fine oxides particles.However,the existence of these strengthening particles also deteriorates the processability and it is of great importance to establish accurate processing maps to guide the thermomechanical processes to enhance the formability.In this study,we performed particle swarm optimization-based back propagation artificial neural network model to predict the high temperature flow behavior of 0.25wt%Al2O3 particle-reinforced Cu alloys,and compared the accuracy with that of derived by Arrhenius-type constitutive model and back propagation artificial neural network model.To train these models,we obtained the raw data by fabricating ODS Cu alloys using the internal oxidation and reduction method,and conducting systematic hot compression tests between 400 and800℃with strain rates of 10^(-2)-10 S^(-1).At last,processing maps for ODS Cu alloys were proposed by combining processing parameters,mechanical behavior,microstructure characterization,and the modeling results achieved a coefficient of determination higher than>99%. 展开更多

Although hazelnut oil is rich in nutrients,its quality is greatly affected by how it is processed.However,no studies to date have comprehensively analyzed the lipid composition of hazelnut oil using different processing methods.Here,we conducted a lipidomics analysis using UPLC-QTOF-MS to characterize the lipid composition of cold-pressed hazelnut oil(CPO),ultrasonic-assisted hexane hazelnut oil(UHO)and enzyme-assisted aqueous hazelnut oil(EAO).A total of 10 subclasses of 98 lipids were identified,including35 glycerolipids(GLs),56 glycerophospholipids(GPs)and 7 sphingolipids(SPs).The total lipid and GL content were the highest in CPO,GP content was the highest in UHO and the ceramide content in SPs was most abundant in EAO.Multivariate statistical analysis showed that the lipid profiles of hazelnut oil prepared with different processing methods varied.Twelve significantly different lipids(TAG 54:3,TAG 52:2,TAG54:4,TAG 54:2,TAG 52:3,TAG 54:5,DAG 36:2,DAG 36:4,DAG 36:3,PC 36:2,PA 36:2 and PE 36:3)were identified,and these lipids could potentially be used as biomarkers to distinguish between hazelnut oil subjected to different processing methods.Our results provide useful information for hazelnut oil applications and new insight into the effects of edible oil processing. 展开更多

This solution can achieve efficient and stable inference performance while reducing computational costs. 展开更多

Dear Editor,A few studies have focused on exploring APOE gene- related effects on cognitive functions and brain activities in healthy populations. Bondi et aL found that ε4 carriers perform significantly worse on the California Verbal Learning Test than non-carriers in non-demented old subjects (mean age, 72 years)ε11. But the results are not entirely consistent. For example, Scarmeas et aL found no effect of the E4 allele on neuropsychological performance[2] in young adults, and Jochemsen et al. found that the ε4 allele is associated with age-related cognitive decline[3]. Furthermore, protective and negative effects of the E2 allele on cognition are inconsistent[4' s]. APOE E2 is thought to be a protective allele for AD in the elderly population due to its role in the superior cognitive performance of ε2 carriers compared to E3 or E4 carriers[5]. However, the ε2 allele has also been found to have a negative effect on AD pathology[4]. 展开更多

This study used non-invasive evaluation methods measured six skin physiological parameters of the lower lip in 180 subjects,including moisture content,transepidermal water loss(TEWL),smoothness(SESM),scaliness of the skin(SESC),wrinkles(SEW),and red area of the lip skin,and compared the effects of 6 groups of lip balms(no-additive group,marine oligosaccharides group,ceramides group,glycyrrhizinic acid group,allantoin group,and mixed group;30 each)on the skin physiological parameters of dry,flaking,and cracked lip subjects.The results showed that the lip mositure content of the subjects in the marine oligosaccharide group,glycyrrhetinic acid group,and allantoin group increased significantly by 44.40%,42.84%and 58.08%after 7 days of lip balm(P<0.05).The TEWL in the ceramide group and the allantoin group was significantly reduced by 21.83%and 24.72%,respectively,after 7 days of lip paste use(P<0.05).The lip skin smoothness values of subjects in the glycyrrhizic acid group and the allantoin group were significantly reduced by 18.76%and 14.97%,respectively,after 28 days of lip balm application(P<0.05).The lip skin scaling indices of subjects in the marine oligosaccharide group,the ceramides group,and the allantoin group were significantly reduced by 33.77%,42.69%,and 38.07%,respectively,after 28 days of lip balm application(P<0.05).The wrinkle parameters of the lip skin of the subjects in the marine oligosaccharide,glycyrrhizinic acid and allantoin groups were significantly reduced by 23.06%,23.29%and 25.98%,respectively,after 28 days of lip balm application(P<0.05).And the area of the red zone of the lip skin of the subjects in the allantoin group was significantly reduced by 4.27%,after 28 days of lip balm application(P<0.05).Combining the effects of the four active ingredients on the secretion of hyaluronic acid(moisturizing effect)and inflammatory factor(IL-6)in HSF cells,it suggests that marine oligosaccharides and allantoin have a perfect impact on enhancing the water content of the skin on the lips of the subjects,and further improve the symptoms of flaking and wrinkles on the lips of the subjects.The ceramide and allantoin can repair the skin barrier well and have a good effect on the chapped and flaky lips of the subjects.After 28 days of using lip balm,the water content of lips in the mixed group increased,the skin barrier was repaired and became smoother,and the wrinkles,scale index,and red zone value were reduced,which could well relieve chronic lip inflammation and lay a foundation for developing lip products for the treatment of chronic cheilitis. 展开更多

Background: In developing countries, charity cleft surgical mission is always operated by sporadic surgical teams without systematic follow up and quality assurance. In the past few decades, many mission projects have been held regularly in China. The purpose of this audit was a retrospective analysis of a 9-year cleft lip and palate charity project operated in a tertiary hospital in China Shenzhen Area to evaluate perioperative and postoperative complications. Nevertheless, understanding the risk profile is essential for establishing a sustainable in-house cleft service in Shenzhen. Methods: A detailed analysis of hospital centralized record in the The University of Hong Kong-Shenzhen Hospital (HKUSZH) was reviewed since the first charity project held in 2015. The parameters of this audit were focused on perioperative complications including anesthesia related problems, early postoperative complications in patients who underwent primary or secondary cleft surgeries. A total of 430 consecutive admitted cases of 311 non-syndromic cleft lip & palate patients were enrolled into the charity project from June 2015 to July 2024. The main anesthesia related complications that occurred during general anesthesia were respiratory tract problems, while intraoperative complication was excessive bleeding, so as wound local infection and reaction were the main early postoperative complications. Results: In our 9-year clinical audit of 430 cleft lip and palate charity surgeries in Shenzhen, we observed no mortalities and a anesthesia-related complication rate of 1.16%. Specific intraoperative complications included excessive bleeding, while early postoperative issues were dominated by wound infections. The fistula rate of 18.7% post palate repair and the average hospital stay of 3.71 days complete the profile of our surgical outcomes. These data underscore the project’s efficacy and offer a reference for international cleft missions aiming for safe and efficient surgical care. Conclusions: This study provides a thorough data review of the complications in the past 9 years charity missions for cleft lip and palate surgery in a well-structured hospital infrastructure and logistic support by local surgical team. There were no perioperative or postoperative death during the study period and the overall short-term complication rate was low. Therefore, it could be a reference model for other international cleft mission in developing country for a safe and efficient service in future. 展开更多

Ti-10V-2Fe-3Al alloy with fine-grainedβphases was fabricated by friction stir processing with opti-mized processing parameters.The superplastic behavior of the specimens was investigated by tensile deformation at different strain rates and temperatures,and an optimal superplastic elongation of 634%was achieved at 700℃ and 3×10^(-4)/s.An annealing treatment at 650℃ for 60 min showed a mi-crostructure withαprecipitates distributed in theβmatrix in the friction stir specimen.Such pre-heat treatment improves the superplasticity of the specimen,achieving an elongation of up to 807%at 750℃ and 3×10^(-4)/s.The influences of tensile temperatures and strain rates on the microstructural evolution,such as grain size variation,grain morphology,and phase transformations,were discussed.The super-plastic deformation behavior of fine-grained Ti-10V-2Fe-3Al alloy is controlled by grain boundary sliding and accompanied by dynamic phase transformation and recrystallization. 展开更多

The hot deformation characteristics of induction quenched Zr-Sn-Nb-Fe-Cr alloy forged rod in the temperature range of 600–900°C and strain rate range of 0.001–1 s^(-1)were studied by Gleeble3800 uniaxial hot compression experiment.The results show that the flow stress decreases with the decrease in strain rate and the increase in deformation temperature in the true stress-true strain curve of Zr-Sn-Nb-Fe-Cr alloy forged rod.Moreover,the hot deformation characteristics of the material can be described by the hyperbolic sine constitutive equation.Under the experimental conditions,the average thermal activation energy(Q)of the alloy was 412.9105 kJ/mol.The microstructure analysis of the processing map and the sample after hot compression shows that the optimum hot working parameters of the alloy are 795–900°C,0.001–0.0068 s^(-1),at the deformation temperature of 600–900°C,and the strain rate of 0.001–1 s^(-1). 展开更多
