The main objective of our work is to predict the market performance of the Dhaka Stock Exchange (DSE) on day closing price using different Deep Learning techniques. In this study, we have used the LSTM (Long Short-Term Memory) network to forecast the data of DSE for the convenience of shareholders. We have enforced LSTM networks to train data as well as forecast the future time series that has differentiated with test data. We have computed the Root Mean Square Error (RMSE) value to scrutinize the error between the forecasted value and test data that diminished the error by updating the LSTM networks. As a consequence of the renovation of the network, the LSTM network provides tremendous performance which outperformed the existing works to predict stock market prices.展开更多

In our previous study, a stable quantitative trait locus(QTL) qIF05-1 controlling the seed isoflavone content in soybean was detected on chromosome(Chr.) 05 in a recombinant inbred line(RIL) population from a cross of Huachun 2×Wayao. In this study, the parental lines were re-sequenced using the Illumina Solexa System with deep coverage. A total of 63,099 polymorphic long insertions and deletions(InDels)(≥15 bp)were identified between the parents Huachun 2 and Wayao. The InDels were unevenly distributed on 20chromosomes of soybean, varying from 1,826 in Chr. 12 to 4,544 in Chr. 18. A total of 10,002 long InDels(15.85% of total) were located in genic regions, including 1,139 large-effect long InDels which resulted in truncated or elongated protein sequences. In the qIF05-1 region, 68 long InDels were detected between the two parents. Using a progeny recombination experiment and genotype analysis, the qIF05-1 locus was mapped into a 102.2 kb genomic region, and this region contained 12 genes. By RNA-seq data analysis, genome sequence comparison and functional validation through ectopic expression in Arabidopsis thaliana, Glyma.05G208300(described as GmEGL3), which is a basic helix-loop-helix(bHLH) transcription factor in plants, emerged as the most likely confirmed gene in qIF05-1. These long InDels can be used as a type of complementary genetic method for QTL fine mapping, and they can facilitate genetic studies and molecular-assisted selection breeding in soybean.展开更多

文摘Soybean seed isoflavones are a type of secondary metabolites that can provide health and nutrition benefits for humans. In our previous study, a stable quantitative trait locus(QTL) qIF05-1 controlling the seed isoflavone content in soybean was detected on chromosome(Chr.) 05 in a recombinant inbred line(RIL) population from a cross of Huachun 2×Wayao. In this study, the parental lines were re-sequenced using the Illumina Solexa System with deep coverage. A total of 63,099 polymorphic long insertions and deletions(InDels)(≥15 bp)were identified between the parents Huachun 2 and Wayao. The InDels were unevenly distributed on 20chromosomes of soybean, varying from 1,826 in Chr. 12 to 4,544 in Chr. 18. A total of 10,002 long InDels(15.85% of total) were located in genic regions, including 1,139 large-effect long InDels which resulted in truncated or elongated protein sequences. In the qIF05-1 region, 68 long InDels were detected between the two parents. Using a progeny recombination experiment and genotype analysis, the qIF05-1 locus was mapped into a 102.2 kb genomic region, and this region contained 12 genes. By RNA-seq data analysis, genome sequence comparison and functional validation through ectopic expression in Arabidopsis thaliana, Glyma.05G208300(described as GmEGL3), which is a basic helix-loop-helix(bHLH) transcription factor in plants, emerged as the most likely confirmed gene in qIF05-1. These long InDels can be used as a type of complementary genetic method for QTL fine mapping, and they can facilitate genetic studies and molecular-assisted selection breeding in soybean.

文摘Over the past few years,Malware attacks have become more and more widespread,posing threats to digital assets throughout the world.Although numerous methods have been developed to detect malicious attacks,these malware detection techniques need to be more efficient in detecting new and progressively sophisticated variants of malware.Therefore,the development of more advanced and accurate techniques is necessary for malware detection.This paper introduces a comprehensive Dual-Channel Attention Deep Bidirectional Long Short-Term Memory(DCADBiLSTM)model for malware detection and riskmitigation.The Dual Channel Attention(DCA)mechanism improves themodel’s capability to concentrate on the features that aremost appropriate in the input data,which reduces the false favourable rates.The Bidirectional Long,Short-Term Memory framework helps capture crucial interdependence from past and future circumstances,which is essential for enhancing the model’s understanding of malware behaviour.As soon as malware is detected,the risk mitigation phase is implemented,which evaluates the severity of each threat and helps mitigate threats earlier.The outcomes of the method demonstrate better accuracy of 98.96%,which outperforms traditional models.It indicates the method detects and mitigates several kinds of malware threats,thereby providing a proactive defence mechanism against the emerging challenges in cybersecurity.

文摘Li plating behavior of the Li metal anode and its compatibility with electrolytes play a decisive role in the electrochemical performance of the Li metal batteries(LMBs),while the intrinsic highly reactive Li would induce serious results especially under deep Li plating/stripping depth and with lean electrolytes.Herein,we propose an innovative strategy to simultaneously regulate the bulk construction and the preferential orientation of Li deposition by introducing Li22Sn5/Li-Mg alloys to realize ultra-stable thin Li anodes with long lifespan.The alloys can form a continuous framework with high lithiophilicity and fast ion-diffusion to enable homogenous Li flux,and meanwhile tune the preferential orientation of Li from the conventional(110)plane to(200)to lower the Li reactivity with electrolytes and optimize Li deposition.Therefore,the thin Li-Sn-Mg alloy anode showcases ultra-stable cycling without volume changes and dendrites under a deep Li plating/stripping depth of 89.1%(5 mAh cm^(-2))for over 1200 h in commercial carbonate electrolytes.Moreover,a multilayered NCM811pouch cell with a high energy density of403.6 Wh kg^(-1)is achieved under the harsh conditions of low N/P ratio(0.769)and lean electrolytes(~2.1 g Ah^(-1)).Synchronously,the thin alloy anode shows improved air stability which benefits the manufacturing process and performance of LMBs,displaying the great application potential of these alloy anodes.

文摘BACKGROUND Colorectal cancer(CRC)is the second most prevalent cause of cancer-related mortality and is increasing in younger individuals.Chemotherapy,a crucial adjuvant systemic therapy for CRC management,often leads to resistance through poorly characterized underlying molecular mechanisms.The long noncoding RNA SNHG5 is highly expressed in CRC and promotes tumor proliferation and invasion,prompting us to hypothesize that SNHG5 may play a crucial role in the chemotherapeutic agent 5-fluorouracil(5-Fu)resistance in CRC.AIM To identify the function and mechanism of SNHG5 in 5-Fu resistance in CRC.METHODS Quantitative real-time polymerase chain reaction was performed to examine the expression of SNHG5 in CRC tissues from 225-Fu-sensitive patients and 145-Fu-resistant patients and in CRC cells and 5-Fu-resistant CRC cells.Cell viability and apoptosis were assessed in SNHG5-overexpressing CRC cells and SNHG5-knockdown 5-Furesistant CRC cells.SNHG5 function in 5-Fu resistance in CRC was further analyzed using a xenograft mouse model.SNHG5 interactions with microRNAs were predicted by bioinformatics analysis.Luciferase reporter and RNA immunoprecipitation assays were performed to verify the binding between SNHG5 and miR-26b.Rescue experiments were performed to validate the functional interaction between SNHG5 and the miR-26b/p-glycoprotein(Pgp)axis.RESULTS SNHG5 expression was upregulated in 5-Fu-resistant CRC tissues and 5-Fu-resistant CRC cells.In vitro functional experiments demonstrated that SNHG5 overexpression significantly reduced cell apoptosis and enhanced cell viability,whereas SNHG5 knockdown in 5-Fu-resistant CRC cells increased cell apoptosis and decreased cell viability upon 5-Fu treatment.In a xenograft mouse model,we confirmed that SNHG5 overexpression led to a reduction in 5-Fu sensitivity in CRC in vivo.Mechanistically,SNHG5 acted as a molecular sponge for miR-26b.Rescue experiments validated that SNHG5 conferred 5-Fu resistance in CRC by regulating the miR-26b/Pgp axis.CONCLUSION SNHG5/miR-26b/Pgp regulates CRC chemosensitivity,providing potential therapeutic targets for the treatment of 5-Fu-resistant CRC.
