An obviously challenging problem in named entity recognition is the construction of the kind data set of entities.Although some research has been conducted on entity database construction,the majority of them are directed at Wikipedia or the minority at structured entities such as people,locations and organizational nouns in the news.This paper focuses on the identification of scientific entities in carbonate platforms in English literature,using the example of carbonate platforms in sedimentology.Firstly,based on the fact that the reasons for writing literature in key disciplines are likely to be provided by multidisciplinary experts,this paper designs a literature content extraction method that allows dealing with complex text structures.Secondly,based on the literature extraction content,we formalize the entity extraction task(lexicon and lexical-based entity extraction)for entity extraction.Furthermore,for testing the accuracy of entity extraction,three currently popular recognition methods are chosen to perform entity detection in this paper.Experiments show that the entity data set provided by the lexicon and lexical-based entity extraction method is of significant assistance for the named entity recognition task.This study presents a pilot study of entity extraction,which involves the use of a complex structure and specialized literature on carbonate platforms in English. 展开更多

Background:The relationship between microRNA(miRNA)expression patterns and tumor mutation burden(TMB)in uterine corpus endometrial carcinoma(UCEC)was investigated in this study.Methods:The UCEC dataset from The Cancer Genome Atlas(TCGA)database was used to identify the miRNAs that differ in expression between high TMB and low TMB sample sets.The total sample sets were divided into a training set and a test set.TMB levels were predicted using miRNA-based signature classifiers developed by Lasso Cox regression.Test sets were used to validate the classifier.This study investigated the relationship between a miRNA-based signature classifier and three immune checkpoint molecules(programmed cell death protein 1[PD-1],programmed cell death ligand 1[PD-L1],cytotoxic T lymphocyte-associated antigen 4[CTLA-4]).For the miRNA-based signature classifier,functional enrichment analysis was performed on the miRNAs.An analysis of the relationship between PD-1,PD-L1,and CTLA-4 immune checkpoint genes was carried out using the miRNA-based signature classifier.Results:We identified 27 differentially expressed miRNAs in miRNA-base signature.For predicting the TMB level,27-miRNA-based signature classifiers had accuracies of 0.8689 in the training cohort,0.8276 in the test cohort,and 0.8524 in the total cohort.The correlation between the miRNA-based signature classifier and PD-1 was negative,while the correlation between PD-L1 and CTLA4 was positive.Based on the miRNA profiling described above,we validated the expression levels of 9 miRNAs in clinical samples by quantitative reverse transcription PCR(qRT-PCR).Four of them were highly expressed and many cancer-related and immune-associated biological processes were linked to these 27 miRNAs.Thus,the developed miRNA-based signature classifier was correlated with TMB levels that could also predict TMB levels in UCEC samples.Conclusion:In this study,we investigated the relationship between a miRNAbased signature classifier and TMB levels in Uterine Corpus Endometrial Carcinoma.Further,this is the first study to confirm their relationship in clinical samples,which may provide more evidence support for immunotherapy of endometrial cancer. 展开更多

Natural Language Processing(NLP)for the Arabic language has gained much significance in recent years.The most commonly-utilized NLP task is the‘Text Classification’process.Its main intention is to apply the Machine Learning(ML)approaches for automatically classifying the textual files into one or more pre-defined categories.In ML approaches,the first and foremost crucial step is identifying an appropriate large dataset to test and train the method.One of the trending ML techniques,i.e.,Deep Learning(DL)technique needs huge volumes of different types of datasets for training to yield the best outcomes.The current study designs a new Dice Optimization with a Deep Hybrid Boltzmann Machinebased Arabic Corpus Classification(DODHBM-ACC)model in this background.The presented DODHBM-ACC model primarily relies upon different stages of pre-processing and the word2vec word embedding process.For Arabic text classification,the DHBM technique is utilized.This technique is a hybrid version of the Deep Boltzmann Machine(DBM)and Deep Belief Network(DBN).It has the advantage of learning the decisive intention of the classification process.To adjust the hyperparameters of the DHBM technique,the Dice Optimization Algorithm(DOA)is exploited in this study.The experimental analysis was conducted to establish the superior performance of the proposed DODHBM-ACC model.The outcomes inferred the better performance of the proposed DODHBM-ACC model over other recent approaches. 展开更多

The term‘corpus’refers to a huge volume of structured datasets containing machine-readable texts.Such texts are generated in a natural communicative setting.The explosion of social media permitted individuals to spread data with minimal examination and filters freely.Due to this,the old problem of fake news has resurfaced.It has become an important concern due to its negative impact on the community.To manage the spread of fake news,automatic recognition approaches have been investigated earlier using Artificial Intelligence(AI)and Machine Learning(ML)techniques.To perform the medicinal text classification tasks,the ML approaches were applied,and they performed quite effectively.Still,a huge effort is required from the human side to generate the labelled training data.The recent progress of the Deep Learning(DL)methods seems to be a promising solution to tackle difficult types of Natural Language Processing(NLP)tasks,especially fake news detection.To unlock social media data,an automatic text classifier is highly helpful in the domain of NLP.The current research article focuses on the design of the Optimal Quad ChannelHybrid Long Short-Term Memory-based Fake News Classification(QCLSTM-FNC)approach.The presented QCLSTM-FNC approach aims to identify and differentiate fake news from actual news.To attain this,the proposed QCLSTM-FNC approach follows two methods such as the pre-processing data method and the Glovebased word embedding process.Besides,the QCLSTM model is utilized for classification.To boost the classification results of the QCLSTM model,a Quasi-Oppositional Sandpiper Optimization(QOSPO)algorithm is utilized to fine-tune the hyperparameters.The proposed QCLSTM-FNC approach was experimentally validated against a benchmark dataset.The QCLSTMFNC approach successfully outperformed all other existing DL models under different measures. 展开更多

Background: Cytotoxic lesions of the corpus callosum (CLOCCs) represent a collection of disparate conditions that can cause a signal change in the corpus callosum, usually involving the splenium. CLOCCs is present in a variety of disorders, such as cerebral infarction, bleeding, multiple sclerosis, acute disseminated encephalomyelitis, glioblastoma, lymphoma, metabolic diseases, and infections. Since 2020, World Health Organization (W.H.O) defined Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, as a pandemic. Numerous CLOCCs cases have been reported in adults in particular in Japan, in China, and recently in children in Turkey associated with SARS-CoV-2. We report the first case of CLOCCs diagnosed in West Africa (Côte d’Ivoire) in an adult associated with SARS-CoV-2. Case Report: A 60 year-old-woman with a medical history of high blood pressure and diabetes, presented to the emergency department with confusion without fever. Neurological examination was normal apart from temporospatial disorientation. Brain magnetic resonance imaging (MRI) showed abnormal signals in the splenium of the corpus callosum (SCC). Forty-eight hours (48 h) after admission, the patient experienced a fever (temperature: 385˚C), several episodes of hypoglycemia (capillary blood glycemia levels below 0.5 g/l) and a dry cough. Lung CT imaging showed typical features with ground-glass opacities. Oropharyngeal swab was positive for SARS-CoV-2 on reverse-transcriptase–polymerase-chain-reaction (RT-PCR) assay. The clinical course was favorable. One month after disease onset, a follow-up Brain MRI showed considerable regression of SCC abnormal signal. The multiple episodes of hypoglycemia and SARS-COV 2 infection were incriminated as the causal factors. Conclusion: The improvement of the technical platform in our context of work gives us the possibility to identify the etiological factors of this rare clinico-radiological entity. 展开更多

Objective: To explore the related factors of surgical treatment of patients with corpus luteum rupture and establish a risk prediction model of surgical treatment of corpus luteum rupture. Methods: 222 patients with corpus luteum rupture treated in Jingzhou First People’s Hospital from January 2015 to March 2022 were analyzed retrospectively, including 45 cases of surgery and 177 cases of conservative treatment. The training set and validation set were randomly assigned according to 7:3. We collected the basic information, laboratory and ultrasonic examination data of 222 patients. Logistic regression analysis was used to determine the independent risk factors and combined predictors of surgical treatment of corpus luteum rupture. The risk prediction model was established and the nomogram was drawn. The discrimination and calibration of the prediction model were verified and evaluated by receiver operating characteristic (ROC) curve, calibration curve and Hosmer-Lemeshow goodness of fit test;Decision curve analysis (DCA) was used to evaluate the clinical effectiveness of the prediction model. Results: Univariate logistic regression showed that whole abdominal pain (OR: 2.314, 95% CI: 1.090 - 4.912), abdominal muscle tension (OR: 2.379, 95% CI: 1.112 - 5.089), adnexal mass ≥ 4 cm (OR: 3.926, 95% CI: 1.771 - 8.266), hemoglobin Conclusion: The nomogram prediction model containing three predictive variables (hemoglobin, depth of pelvic effusion under ultrasound and cervical lifting pain) can be used to predict the risk of surgical treatment in patients with corpus luteum rupture. 展开更多

Aim: To establish an objective, easy-to-use and comprehensive method to analyze corpus cavernosum electromyo- graphic signals (CC-potentials). Methods: CC-potentials were recorded during flaccidity in 23 young healthy volunteers, with surface electrodes placed on the penile shaft bilaterally. Based on the correlation function of Matlab software, an application program for the analysis of CC-potentials was developed. Individual CC-potentials and their autocorrelation function were evaluated, yielding parameters amplitude (A), duration (D), and dominant frequency (DF). The crosscorrelation function of both longitudinal and bilateral pairs of adjacent electrodes was calculated to assess the similar- ity and mutual delay of CC-potentials recorded simultaneously from different parts of the CC. The parameters derived were squared maximum cross-correlation coefficient (Rmax) and delay (τ). Based on the absolute value of τ and the corresponding inter-electrode distance, propagation velocity (PV) was calculated. Results. The values of the parameters were determined automatically. No significant difference related to the locations of the electrodes for parameters A, D, and DF was detected. The cross-correlation showed that both longitudinal and bilateral CC-potential pairs had highly similar waveforms (the absolute values of Rmax were 0.80 ± 0.05 and 0.87 ± 0.06, respectively). PV of longitudinal pairs was estimated as 6.15 ± 3.98 cm/s. Conclusion: The application program for correlation analysis of CC-potentials is a comprehensive and versatile method to analyze corpus cavernosum electromyographic recordings. Its objectiveness makes multi-center application possible. 展开更多
