Vulnerabilities are a known problem in modern Open Source Software(OSS).Most developers often rely on third-party libraries to accelerate feature implementation.However,these libraries may contain vulnerabilities that attackers can exploit to propagate malicious code,posing security risks to dependent projects.Existing research addresses these challenges through Software Composition Analysis(SCA)for vulnerability detection and remediation.Nevertheless,current solutions may introduce additional issues,such as incompatibilities,dependency conflicts,and additional vulnerabilities.To address this,we propose Vulnerability Scan and Protection(VulnScanPro),a robust solution for detection and remediation vulnerabilities in Java projects.Specifically,VulnScanPro builds a finegrained method graph to identify unreachable methods.The method graph is mapped to the project’s dependency tree,constructing a comprehensive vulnerability propagation graph that identifies unreachable vulnerable APIs and dependencies.Based on this analysis,we propose three solutions for vulnerability remediation:(1)Removing unreachable vulnerable dependencies,thereby resolving security risks and reducing maintenance overhead.(2)Upgrading vulnerable dependencies to the closest non-vulnerable versions,while pinning the versions of transitive dependencies introduced by the vulnerable dependency,in order to mitigate compatibility issues and prevent the introduction of new vulnerabilities.(3)Eliminating unreachable vulnerable APIs,particularly when security patches are either incompatible or absent.Experimental results show that these solutions effectively mitigate vulnerabilities and enhance the overall security of the project. 展开更多

The accuracy of genomic annotation is crucial for subsequent functional investigations;however,computational protocols used in high-throughput annotation of open reading frames(ORFs)can introduce inconsistencies.These inconsistencies,which lead to non-uniform extension or truncation of sequence ends,pose challenges for downstream analyses.Existing strategies to rectify these inconsistencies are time-consuming and labor-intensive,lacking specific approaches.To address this gap,we developed to GC,a tool that integrates genomic annotation with RNA-seq datasets to rectify annotation inconsistencies.Using to GC,we achieved an accuracy of nearly 100%accuracy in correcting inconsistencies in published Phytophthora sojae ORFs.We applied this innovative pipeline to the GPCR-bigrams gene family,which was predicted to have 42 members in the P.sojae genome but lacked experimental validation.By employing to GC,we identified 32 GPCR-bigram ORFs with inconsistencies between previous annotations and to GC-corrected sequences.Notably,among these were 5 genes(GPCR-TKL9,GPCR-TKL15,GPCR-PDE3,GPCR-AC3,and GPCR-AC4)showed substantial inconsistencies.Experimental gene annotation confirmed the effectiveness of to GC,as sequences obtained through cloning matched those annotated by to GC.Importantly,we discovered two novel GPCRs(GPCR-AC3 and GPCR-AC4),which were previously mispredicted as a single gene.CRISPR/Cas9-mediated knockout experiments revealed the involvement of GPCR-AC4 but not GPCR-AC3 in oospore production,further confirming their status as two separate genes.In addition to P.sojae,the reliability of the to GC pipeline in Phytophthora capsici and Pythium ultimum further emphasizes the robustness of this pipeline.Our findings highlight the utility of to GC for reliable gene model correction,facilitating investigations into biological functions and offering potential applications in diverse species analyses. 展开更多

At present, enhancing the digital literacy of village cadres faces practical constraints such as governance capability gaps induced by the second-level digital divide, the absence of a systematic cultivation system, incomplete last-kilometer implementation for translating skills into practice, and inadequate incentive mechanisms. As a novel educational form deeply integrating digital information technology with teaching and learning, distance open education provides multi-directional empowerment for enhancing village cadres digital literacy. This is achieved through open learning methods, the application of modern digital technologies, tailored learning programs, and the establishment of "overpass bridges" for translating learning outcomes into practice. Based on this, it is essential to further streamline the pathways for educating and cultivating village cadres, vigorously promote the digitalization of teaching, practice, and support services, develop systematic and localized digital education resources, and actively explore and establish a complementary credit bank system for their digital literacy cultivation. 展开更多

Objective:Robotic-assisted living donor nephrectomy(RALDN)has been shown to be a safe and feasible option,offering enhanced visualization and improved surgical dexterity,allowing for a potential increase in the living donor pool to perform pediatric and adult kidney transplants,even in cases of grafts with anatomical variants.We report our recent experience in using RALDN for open kidney transplantation(OKT).Methods:Between August 2021 and July 2025,122 kidney transplant recipients underwent OKT using RALDN grafts obtained at the Miami Transplant Institute.Clinical outcomes,during the first12 months post-transplant,including the incidence of delayed graft function(DGF),surgical complications,estimated glomerular filtrationrate(eGFR),and graft loss,were evaluated.Results:Sixteen pediatric and 106 adult recipients were included.The median recipient and donor ages were 42.2 yr and 39.5 yr,respectively.Male recipients comprised 63.1%(77/122);female donors comprised 56.6%(69/122).Among the donors,no conversion to open surgery was needed,and no postoperative complications attributed to the RALDN procedure were observed.Thirty-one kidney grafts required back table reconstruction.The median cold and warm ischemia times were 55.5 min and 27.0 min,respectively.One case(0.8%)of DGF was observed.One recipient(0.8%)developed a postoperative vascular complication;five(4.1%)developed a urologic complication.The median eGFRs at 1 mo,3 mo,6 mo,and 12 mo post-transplant were 71.9,77.1,75.1,and 72.1 mL/min/1.73 m2,respectively.No cases of graft failure during the first12 months post-transplant were observed,and one patient died with a functioning graft.Conclusion:RALDN is a safe and effective technique that provides favorable outcomes among both donors and recipients.This minimally invasive approach should be offered as a safe alternative to living donor patients. 展开更多

Plants encounter dynamic light environments in natural field conditions,and species differ in their physiological and biochemical mechanisms for acclimating to fluctuating light(FL).The manner in which soybean(Glycine max(L.) Merr.) coordinates multiple physiological adjustments to FL remains poorly understood.This study assessed the effects of FL on soybean morphology and photosynthetic traits by examining changes in photosynthetic gas exchange parameters and chlorophyll(Chl) a fluorescence under alternating high-and low-light conditions.Results indicated that soybeans exposed to FL exhibited reduced dry matter accumulation,smaller and thinner leaves,and a lower Chl a/Chl b levels-characteristics typically associated with plants grown under continuous low-light.Despite these morphological similarities,their photosynthetic gas exchange rates and photosynthetic capacity were maintained at levels comparable to those under steady high light,unlike plants grown under constant low-light.Thus,acclimation to FL is distinct from adaptation to sustained low-light conditions.Correlation analyses revealed that the decline in carbon assimilation under FL primarily stemmed from two factors:the slow recovery of stomatal conductance upon transition to high light and the delayed relaxation of nonphotochemical quenching when light intensity decreased.Therefore,the reduction in carbon assimilation under FL cannot be attributed to low-light phase adjustments but rather reflects a lag in photosynthetic responsiveness to changing light conditions. 展开更多

The next-generation RAN,known as Open Radio Access Network(ORAN),allows for several advantages,including cost-effectiveness,network flexibility,and interoperability.Now ORAN applications,utilising machine learning(ML)and artificial intelligence(AI)techniques,have become standard practice.The need for Federated Learning(FL)for ML model training in ORAN environments is heightened by the modularised structure of the ORAN architecture and the shortcomings of conventional ML techniques.However,the traditional plaintext model update sharing of FL in multi-BS contexts is susceptible to privacy violations such as deep-leakage gradient assaults and inference.Therefore,this research presents a novel blockchain-assisted improved cryptographic privacy-preserving federated learning(BICPPFL)model,with the help of ORAN,to safely carry out federated learning and protect privacy.This model improves on the conventional masking technique for sharing model parameters by adding new characteristics.These features include the choice of distributed aggregators,validation for final model aggregation,and individual validation for BSs.To manage the security and privacy of FL processes,a combined homomorphic proxy-reencryption(HPReE)and lattice-cryptographic method(HPReEL)has been used.The upgraded delegated proof of stake(Up-DPoS)consensus protocol,which will provide quick validation of model exchanges and protect against malicious attacks,is employed for effective consensus across blockchain nodes.Without sacrificing performance metrics,the BICPPFL model strengthens privacy and adds security layers while facilitating the transfer of sensitive data across several BSs.The framework is deployed on top of a Hyperledger Fabric blockchain to evaluate its effectiveness.The experimental findings prove the reliability and privacy-preserving capability of the BICPPFL model. 展开更多
