Abstract:Elemental red phosphorus,as a novel non-metallic semiconductor material,has garnered signifi-cant attention in the fields of energy conversion and environmental remediation.In this study,commercial red phosphorus was modified through hydrothermal treatment,and the modified elemental red phosphorus with varying hydrothermal treatment durations was employed for the effective adsorption and reduction of Cr(Ⅵ).Comprehensive analysis using advanced characterization techniques was conducted to investigate the performance,relevant characteristics,and critical parameters governing the adsorption and reduction processes of Cr(Ⅵ)by red phosphorus.The study specifically delved into the impacts of optimal hydro-thermal treatment durations,pH values,adsorption concentrations,and presence of coexisting ions on the removal efficiency of Cr(Ⅵ)by red phosphorus.By integrating kinetic investigations,the underlying ad-sorption and reduction mechanisms employed by red phosphorus against Cr(Ⅵ)were elucidated.The ex-perimental findings demonstrated that the hydrothermal treatment enhanced the active sites on elemental red phosphorus by augmenting its specific surface area,consequently boosting the material's adsorption capacity towards Cr(Ⅵ).Notably,the optimized sample RP-24 exhibited remarkable effectiveness in ad-sorbing Cr(Ⅵ),displaying a saturated adsorption capacity of 42 mg/g.Furthermore,the adsorption process adhered to quasi-second-order kinetics and conformed to the Langmuir isothermal model.Follow-ing adsorption,the modified elemental red phosphorus efficiently facilitated the complete reduction of Cr(Ⅵ)to Cr(Ⅲ)through the photocatalytic pathway.

Abstract:Plastic deformation transfer between grains critically influences the mechanical behavior of ma-terials.Based on the phenomenon of deformation transfer between grains we propose two physical quanti-ties to describe the tendency of the strain transfer between grains:slip misorientation and twinning misori-entation.This work elaborates on the concepts of mathematical formulations and derivations of these pa-rameters.These parameters directly characterize deformation transfer across grains under deformation modes,enabling statistical analysis and prediction.They provide a new approach for studying polycrystal-line plastic deformation.

Abstract:Microwave signal frequency measurement technology has an important application in modern science and technology,which is widely used in communication,radar,navigation and sensing and other fields.At present,the microwave frequency measurement based on electronics has been very mature,but there are still drawbacks such as susceptible to electromagnetic interference,difficult to realize high fre-quency and large range measurement.Microwave photonics technology,which integrates the advantages of photonics and electronics,can effectively overcome the above problems,and has obvious advantages in high-frequency broadband micro wave signal measurement,such as large bandwidth,high frequency,and anti-electromagnetic interference.This paper introduces the main microwave photon frequency measure-ment technology of the basic principles and typical implementation of the program,a systematic review of recent years based on microwave photonics microwave frequency measurement technology research pro-gress,and finally on the major categories of frequency measurement technology advantages and disadvan-tages of a comparative analysis,and look forward to the future development of microwave photon frequen-cy measurement technology.

Abstract:Graphitic carbon nitride(g-C3N4),a visible-light-responsive photocatalyst,faces the challenge of simultaneously achieving doping modification and low-dimensional morphology control.In this study,a supramolecular precursor was formed by connecting melamine and cyanuric acid through triple hydrogen bonds.Vanadium-doped g-C3N4 nanotubes were prepared by adding vanadium salts,followed by drying and calcination.Vanadium doping induced the self-fission of the supramolecular precursor into nanotubes,which optimized the electronic structure of g-C3N4 and increased its specific surface area.The effects of va-nadium doping on the photoelectrochemical properties and photocatalytic hydrogen production performance of g-C3N4 were systematically investigated.The results showed that the highest hydrogen production per-formance of vanadium-doped g-C3N4 under visible light irradiation was 599.1 μmol·h-1·g-1,which was 2.8 times that of pure g-C3N4 This enhancement was mainly attributed to the synergistic effect of the broadened light absorption range,reduced electron transfer resistance,and increased specific surface area.

Abstract:xIn2O3/BiOBr S-scheme heterojunction(x%is the mass fraction of In2O3 to BiOBr)composite photocatalysts were successfully prepared by a water bath impregnation method.The morphology,struc-ture,specific surface area,light absorption property,the separation and transfer efficiency of photogener-ated carriers of catalysts were studied.The results showed that In2O3 and BiOBr were tightly bound,and In2O3 was uniformly dispersed on BiOBr nanoflowers.The xIn2O3/BiOBr composite photocatalyst exhibi-ted stronger absorption of visible light,and the addition of In2O3 improved the separation efficiency of the photogenerated carrier on BiOBr.The photocatalytic CO2 reduction reaction over xIn2O3/BiOBr was stud-ied under visible light irradiation.When the In2O3 loading mass percentage was 5%,5In2O3/BiOBr exhib-ited the best performance for photocatalytic CO2 reduction,and the CO production reached 16.12 μmol/g after reaction for 4 h,which was 1.68 times that of BiOBr.

Abstract:In this paper,a new fuzzy control problem for a class of Chua's circuits under impulsive and sto-chastic influences is investigated.The relationship between the eigenvalues and the performance of the sys-tem is first used to define the interval stability of the Chua's circuit system.The definition reflects the con-vergence rate of the system in addition to the stability of the system.On this basis,an intelligent fuzzy controller with adjustable convergence rate is designed to limit the convergence rate of the Chua's circuit while ensuring the stability of the Chua's circuit.The Chua's circuit variable convergence rate algorithm is given,which can speed up or slow down the convergence rate of the Chua's circuit as needed.Finally,the effectiveness and practicality of the proposed control criterion is verified by Chua's circuit system.

Abstract:The crowdsourced software development model harnesses global developer resources to enable efficient software development,yet information overload on platforms poses challenges in recommending suitable developers.Existing recommendation algorithms rely on developer attributes and interaction be-haviors,but incomplete developer profiles in crowdsourced platforms hinder recommendation perform-ance.To address this,we propose an Attribute-Completion Developer Recommendation algorithm via De-coupled Graph Convolution(ADD).ADD comprises two modules:an attribute inference module and an attribute completion module.The attribute inference module leverages decoupled graph convolution to de-duce developer attributes across multiple latent spaces,while the attribute completion module fills missing attributes using inferred results.The completed attributes are iteratively fed back into the inference mod-ule,forming a cyclic optimization process until convergence.Upon convergence,the model achieves peak attribute inference capability,generating attributes that closely reflect real-world scenarios.Experiments on real-world datasets demonstrate that ADD significantly outperforms state-of-the-art models in MAE,RMSE,Precision,and Recall metrics,effectively resolving information incompleteness in crowdsourced developer recommendations.

Abstract:With regard to the recent surge of mortality rate of ornamental Sophora japonicas planted in Li-aocheng city,the soil physiochemical properties and microbial community composition in rhizosphere soils of S.japonica were analyzed,thereby revealing the correlation between the growth status of S.japonica and the soil environment.The results showed that all the rhizosphere soil samples across diverse growth states of S.japonica contained medium to high levels of organic substances,total nitrogen,total phos-phorus,and total potassium,with a notable abundance of available potassium.Conversely,water-soluble nitrogen and available phosphorus were at medium to low levels.In terms of microbial communities,the rhizosphere soil of dead S.japonica possessed significantly higher bacterial species diversity and richness but lower fungal species diversity and richness in comparison with those of weakened and healthy growing S.japonica.Additionally,the rhizosphere soil of dead S.japonica exhibited greater relative abundances of saprophytic genera,such as Agaricus and Peziza,as well as Fusarium responsible for root rot.In con-trast,the rhizosphere soil of healthy S.japonica showed stronger presence of the bio-stimulating fungus Mortierella genera.The research results are expected to provide important theoretical guidance for the cultivation and management of Sophora japonica.

Abstract:Photo-thermal catalytic CO2 methanation is a promising strategy to mitigate the greenhouse effect and address the energy crisis.However,it still faces several challenges in achieving ideal conversion efficiency and high selectivity for target products.In this work,a method was proposed to in situ grow Ni nanoparticles on the surface of Al2O3 nanosheets for photo-thermal catalytic CO2 hydrogenation to CH4.X-ray photoelectron spectroscopy reveals a strong interaction between the Ni nanoparticles and the Al2O3 support,allowing efficient electron transfer from Ni to the Al2O3 surface,which facilitates the adsorption and activation of reactants.Experimental results show that the Ni/Al2O3-3 catalyst exhibits the highest CO2 hydrogenation activity,with a CH4 yield of 32.4 mmol·g-1·h-1 and a selectivity of 93.3%,which is 3.4 times higher than that of the Ni-Al2O3 catalyst prepared by conventional impregnation.Moreover,mechanism studies manifest that the CO2 methanation reaction on Ni/Al2O3 catalysts follows the formate pathway,and light irradiation effectively promotes the activation and conversion of reactants and interme-diate,thereby enhancing catalytic activity.

Abstract:A wavelength-tunable mode-locked laser based on femtosecond laser direct writing of long-peri-od fiber gratings(LPFGs)is reported in this paper.Using a femtosecond laser,an LPFG with a period of 50 μm was inscribed,which exhibits a 3 dB bandwidth of 12.09 nm for its transmission peak near 1 032.67 nm.The LPFG was utilized as a filter in a ytterbium-doped fiber mode-locked laser,resulting in stable mode-locked pulses.By altering the refractive index of the surrounding medium,the transmission wave-length of the LPFG shifts accordingly.When the refractive index of the medium varies within the range of 1.40 to 1.43,the operating wavelength of the mode-locked laser is tunable from 1 046.42 nm to 1 060.25 nm,with a total tuning range of 13.83 nm.Compared to other wavelength tuning methods,the fiber grat-ing inscribed by femtosecond laser direct writing features a simple structure,flexible parameters,and ease of integration with fiber devices.

Abstract:The rapid development of PD-1/PD-L1 immune checkpoint inhibitors has revolutionized cancer therapy,yet challenges persist in enhancing their therapeutic efficacy.Antibody-drug conjugates(ADC)have the potential to significantly expand the therapeutic window of chemotherapy agents while synergisti-cally activating immune responses.However,the drug-antibody ratio(DAR)may affect key attributes such as activity and stability.To date,research on next-generation PD-L1-targeted ADC with varying DAR values remains limited.In this study,we first developed tumor microenvironment-responsive PD-L1 ADC with different DAR values using various anti-PD-L1 antibodies.These conjugates were subjected to preliminary characterization,activity evaluation,and stability analysis.Our findings demonstrate that both the antibody type and DAR significantly influence the activity and stability of PD-L1 ADC.The de-velopment of next-generation PD-L1 ADC requires a comprehensive consideration of efficacy,drugability,and other factors.This study provides crucial experimental evidence and conceptual frameworks for the ra-tional design and mechanistic exploration of PD-L1-targeted ADC.

Abstract:This study investigates the inhibitory effects and underlying mechanisms of ethanol extract of Chinese propolis(EECP)on the proliferation of human colorectal cancer cells(HCT116)through modula-tion of N6-methyladenosine(m6A)RNA methylation.HCT116 cells were treated with varying concentra-tions of EECP(25,50,and 100 μg/mL).Cell proliferation was assessed using the CCK-8 assay,while the global m6A modification levels of total RNA were measured by dot blot analysis.The mRNA and protein expression levels of Methyltransferase-like 3(METTL3),Methyltransferase-like 14(METTL14),Wilms Tumour 1-Associating Protein(WTAP)and Fat Mass and Obesity-associated Protein(FTO)were evalua-ted using real-time quantitative PCR(RT-qPCR)and Western blot,respectively.The results demonstra-ted that increasing concentrations of EECP significantly reduced the total RNA m6A levels in HCT116 cells(p＜0.05).Additionally,EECP treatment led to decreased expression levels of FTO,WTAP and METTL3,while METTL14 expression was significantly upregulated(p＜0.05).In conclusion,EECP induces alterations in m6A methylation and related enzyme expression in HCT116 cells,suggesting that EECP may exert anti-colorectal cancer effects by regulating m6A methylation.

Abstract:This study aims to enhance the antioxidant activity and bioavailability of Coenzyme Q10(CoQ10)by preparing CoQ10 nanoemulsion using medium chain triglycerude as the oil phase,soybean phospholipid as the surfactant,and Tween-80 as the co-surfactant.The preparation process of CoQ10 nanoemulsion was optimized using Box-Behnken response surface methodology.Also,the physicochemical properties,stability,antioxidant activity,and bioavailability of the CoQ10 nanoemulsion were investiga-ted.The results show that the optimal conditions for CoQ10 nanoemulsion were 2 g of medium chain trig-lycerude,5.353 g of soybean phospholipid,and 1 g of Tween-80.In this case,the average particle size,polydispersity index,zeta potential,and encapsulation efficiency of the CoQ10 nanoemulsion were(72.9±0.32)nm,0.25±0.034,(-34.9±1.97)mV,and(97.6±0.49)%,respectively.Transform infrared spectroscopy results show that CoQ10 was completely encapsulated in the nanoemulsion.Moreover,the result of Transmission Electron Microscopy indicates that the CoQ10 nanoemulsion were round,non-ag-gregated,and evenly dispersed in the system.The stability experiments demonstrate that CoQ10 nanoe-mulsion displayed better centrifugal stability,ionic stability,and storage stability.Additionally,com-pared to CoQ10 suspensions,the DPPH free radical,ABTS free radical,and hydroxyl free radical scaven-ging rates of CoQ10 nanoemulsion was increased by 79.1%,93.1%and 72.2%,respectively.The blood concentration of CoQ10 in rats for the optimized CoQ10 nanoemulsion was 0.767 Pg/mL,which was 1.405 times that of CoQ10 oil.This study could provide data support for the development of Coenzyme CoQ10 nanoemulsion,and lay the foundation for its application in health food and biomedicine fields.

Abstract:Objective:To investigate the effects and mechanisms of the combined use of induced pluripotent stem cell-derived mesenchymal stem cells(iPSC-MSCs)with β-hydroxy-β-methylbutyrate(HMB)and D-ribose(DR)on myotube atrophy.Method:In this study,the C2C12 cell line was selected as the research subject,and an in vitro muscular atrophy model was successfully constructed with the aid of dexametha-sone(Dex).The experimental design encompassed a Control group,a Dex group,and groups receiving iPSC-MSCs,HMB,and DR,as well as their combined treatments.Cell viability was evaluated using the CCK8 assay,myotube morphology was observed through HE staining,and concurrently,molecular bio-logical methods such as Western blot and immunofluorescence analysis were also applied to conduct in-depth exploration of the experimental mechanisms.Results:Compared with the Dex group,the iPSC-MSCs+HMB+DR+Dex group significantly increased C2C12 myotube cell viability(***P＜0.001)and myotube diameter(***P＜0.001).Western blot results showed that the iPSC-MSCs+HMB+DR+Dex group exhibited significantly increased protein expression of P-PKB(**P＜0.01),P-mTOR(**P＜0.01),PI3K(*P＜0.05),PGC-1(*P＜0.05),IGF-1(**P＜0.01),MHC(*P＜0.05),Pax-7(*P＜0.05),and MyoD-1(*P＜0.05).Meanwhile,there were significant decreases in the protein expression of Foxo3a(**P＜0.01),MuRF-1(*P＜0.05),Caspase-3(*P＜0.05)and Bax(*P＜0.05),as well as a significant reduction in the Bax/Bcl-2 ratio(**P＜0.01)..The immunofluorescence results were consist-ent with the Western blot findings,indicating that compared with the Dex group,the iPSC-MSCs+HMB+DR+Dex group had significantly decreased protein expression of MuRF-1(***P＜0.001)and signifi-cantly increased protein expression of Pax-7(***P＜0.001).Conclusion:This study has discovered that the combined application of iPSC-MSCs,HMB,and DR can significantly ameliorate the atrophy induced by Dex in C2C12 myotubes.This positive effect may be attributed to the following mechanisms:Firstly,this combined therapy can activate the PI3K/PKB signaling pathway,thereby promoting protein synthe-sis.Secondly,by reducing the Bax/Bcl-2 ratio and inhibiting the expression of Caspase-3 protein,it effec-tively halts the process of cellular apoptosis.Lastly,it also significantly increases the expression levels of MHC,Pax-7,and MyoD-1,which play crucial roles in muscle growth and differentiation.

Abstract:In order to reveal the gene function and mechanism of Allene Oxide Synthase(AOS),bioinfor-matics methods were used to identify AOS family members at the maize genome level,and the expression level AOS genes were analyzed by real-time fluorescence quantitative polymerase chain reaction under abi-otic stress.Finally,seven maize AOS(named ZmAOS)genes were identified at the genome-wide level and distributed on four chromosomes.Furthermore,the seven ZmAOS genes were divided into four sub-groups of evolutionary branches,and the gene structure and protein sequences were relatively conserved within each group,but there were large differences between groups,suggesting that there may be func-tional differences.Besides,the analysis of cis-acting elements and stress expression patterns showed that ZmAOS genes may be involved in maize growth,development and stress response.And the interaction protein prediction that ZmAOS may interact with LOX,AOC,HPL,OPR and so on,and then participate in the jasmonic acid pathway to regulate plant growth and development,and respond to abiotic stress.

Abstract:Approximate reasoning plays a crucial role in many fields such as fuzzy control,image process-ing,and data mining.In the reasoning process,it is often required that when the same linguistic modifiers are added to the antecedent and consequent of a reasoning rule,the truth value of the rule remains un-changed.This requires that the operator reflecting the reasoning process,namely,fuzzy implication,has power invariance.T-power based implication,as an important class of fuzzy implications satisfying this property,is obtained by generalizing Zadeh's linguistic powering modifiers to relax the consequent.In-spired by this method,by generalizing Zadeh's linguistic powering modifiers to relax the antecedent,a class of fuzzy implications based on the powers of continuous t-conorms,namely,S-power based implica-tion,is proposed.The research about the properties and characterization of S-power based implication as well as its relationship with common classes of fuzzy implications,shows that S-power based implication is a new class of fuzzy implications,and most of its members satisfy power invariance with respect to contin-uous t-conorms.In addition,the research on the generalized hypothetical syllogism(GHS)in the reason-ing mechanism of S-power implication,will further provide a theoretical basis for the research on applica-tions such as fuzzy control,image processing,and data mining.
