Isquemia recurrente posterior a infarto agudo de miocardio en el adulto mayor
Authors: Murillo Pérez Luis , Rodríguez Urteaga Zoila
Published: April 2022

Se presenta el caso de un paciente varón de 62 años que cursó con dolor torácico opresivo; fue diagnosticado de infarto agudo de miocardio y recibió tratamiento de reperfusión con angioplastia primaria. En la evolución cursó con un nuevo episodio de infarto de miocardio, por lo que se realizaron estudios complementarios que condujeron al diagnóstico de arteritis de Takayasu. Desafortunadamente, presentó una evolución tórpida a pesar del manejo instaurado. Es infrecuente la presentación clínica en pacientes mayores de 60 años, por ello es importante considerarlo dentro del diagnóstico diferencial en pacientes con enfermedad coronaria difusa e isquemia miocárdica recurrente, debido a la rápida progresión y elevada morbimortalidad, incluso a pesar de estrategias de revascularización exitosas.

Published: April 2022

Coronary artery bypass using bilateral internal thoracic artery (BITA) has been related to survival benefits in patients with coronary artery disease, but data is not conclusive. In South America, several centers reported their own experience with good results in survival, minimal postoperative cardiovascular events, and a low degree of mediastinal infection, however, the number of cases is low, and the absence of publications in several countries is a matter of concern. We review the leading publications on BITA grafting in our region, assessing how far we have advanced in coronary surgery.

Authors:   The Holy Family Hospital, Nazareth, Israel, Gil Ziv , Billan Salem ,   The Holy Family Hospital, Nazareth, Israel,   Oncology Section, Rambam Health Care Campus, Haifa, Israel
Published: April 2022

In the management of malignant thyroid disorders, the standard primary treatment is thyroidectomy, a surgical resection of the thyroid gland. This procedure has been performed for over a century. Hence, it comes as no surprise that it is not only exceedingly well-described in the literature. This issue of Rambam Maimonides Medical Journal includes an article by Chaturvedi et al. that challenges the standard widely-practiced clinical inclination toward surgery as the first and best option for all patients with early thyroid cancer. This editorial discusses the issues raised by the authors and points out the importance of ongoing research to determine when standards of care should be modified in the light of low-risk disease.

Diagnosis of varicose veins
Authors: Ohe Haeng Jin , Kim Song-Yi
Published: April 2022

Background: Varicose veins refer to tortuous engorged veins on the lower extremities. Although this is a common condition observed in clinical practice, objective diagnosis is important for optimal treatment.Current Concepts: Thorough physical examination is the first key step for diagnosis of varicose veins. Both legs should be examined between the inguinal region and the feet with the patient in an erect position. The presence and location of venous reflux should be confirmed using duplex ultrasonography (DUS), which serves as a simple, non-invasive modality to assess both the anatomy and physiology of leg veins. Reflux is defined as duration of retrograde flow greater than 0.5 seconds in superficial veins, 0.35 seconds in perforating veins, and 1.0 seconds in deep veins. Computed tomography venography can be used in selective cases as a complementary tool to obtain objective images of all varicose veins; however, this imaging modality cannot confirm venous reflux.Discussion and Conclusion: DUS is a key diagnostic tool for varicose veins. However, DUS results are operator dependent; therefore, this procedure should be performed by experienced technologists or clinicians, based on guidelines. The location and duration of reflux should be recorded.
Second-generation treatment of varicose veins: endovenous thermal ablation by laser or radiofrequency ablation
Authors: Kim Mi-Hyeong , Choi Chanjoong
Published: April 2022

Background: Endovenous thermal ablation (EVTA) is the second-generation treatment of varicose veins in the lower extremities. It has overcome the shortcomings of the first-generation treatment of high ligation and stripping. Further, it is the basis for the development of the third-generation treatment with endovenous glue ablation. It is currently recommended as the first-line treatment for varicose veins accompanied by great saphenous vein incompetence.Current Concepts: EVTA involves obliterating the varicosed veins by applying thermal energy to blood or vein wall. It can be performed by laser or radiofrequency ablation methods, under local anesthesia. The treatment results are excellent and show lesser pain and faster recovery compared to the first-generation treatment. However, complications include endovenous heat-induced thrombosis, deep vein thrombosis, ecchymosis, and phlebitis.Discussion and Conclusion: To enhance the therapeutic effect and reduce the complications of EVTA, sufficient tumescent anesthesia, a controlled number of firing in radiofrequency ablation, and use of the novel highwavelength laser and a radial catheter tip in endovenous laser ablation are recommended. In addition, proficiency in other generations of varicose vein treatments could help in various situations.
Anatomically Corrected Malposition of the Great Arteries with Atrioventricular Concordance and Left Juxtaposition of the Atrial Appendages
Authors: Aslan Eyup , Isık Onur , Akyuz Muhammed
Published: April 2022

Anatomically corrected malposition of the great arteries is a rare cardiac malformation. In this condition the great arteries are abnormally related to each other and to the ventricles, but arise from the anatomically correct ventricles. In patients with atrioventricular concordant and the absence of associated anomalies, the circulation is physiologically normal. However, ventricular septal defect and right ventricular outflow tract stenosis are the most common accompanying pathologies that require surgical intervention. Here, we present a 9-day-old female with anatomically corrected malposition of the great arteries with wide atrial septal defect, mild right ventricular outflow tract stenosis, left juxtaposition of the atriums, and wide malalignment subaortic ventricular septal defect that required aortotomy to close the defect.

Authors: Çiğ Esranur , Atar Muge , Pirgon Ozgur
Published: April 2022

This retrospective study was planned to examine the relationship between glucose metabolism, androgen and lipid profiles after vitamin D and metformin treatments in adolescent girls with hyperandrogenism. Forty-five adolescent female patients diagnosed with hyperandrogenism were divided into three groups. The first group of patients was given metformin (M), the second group was given metformin and vitamin D drops (MdD), and the third group were those who received oral metformin and vitamin D ampoules (MsD). Biochemical and hormonal parameters at the end of 8 weeks were compared statistically. The vitamin D level was higher in the metformin-vitamin D stoss treated group than metformin-vitamin D drops. There was a positive correlation between vitamin D and SHBG in the metformin group (r =0.65, p<0.01). A significant correlation was observed between triglyceride and insulin in both groups given vitamin D, and there was a decrease in these two values (p<0.05). There was a positive correlation between total testosterone and Alanine transaminase (ALT) in the MsD group (p<0.05). Additionally, a positive correlation was observed between SHBG and HDL-cholesterol in three groups. There was a significant correlation between androgen and lipid parameters in the 8-week metformin and vitamin D treated groups. Long-term studies using high-dose vitamin D are needed to support our results.
Can Point Shear Wave Elastography be Used as an Indicator of Metabolic Complications in Overweight Children and Adolescents? Evaluation of Subcutaneous Adipose Tissue
Authors: Karaman Zehra Filiz , Hatipoğlu Nihal
Published: April 2022

This study aims to search the association of obesity, metabolic parameters, and abdominal subcutaneous white adipose tissue (scWAT) stiffness in children and adolescents using ultrasound point shear wave elastography (p-SWE). One hundred and forty overweight or obese children referred to as overweight were included in the study group. Thirty-two lean children, referred to as leans, were included in the control group. In all individuals, scWAT shear wave speed (SWS) was measured with p-SWE.  ScWAT stiffness was compared between the two groups. The association of anthropometric, metabolic factors and scWAT stiffness is determined. Weight, body mass index, body mass index-standard deviation score, systolic blood pressure, diastolic blood pressure, alanine aminotransferase, fasting insulin were significantly higher in the overweight group (p<0,05). ScWAT SWS was significantly different between the groups (p=0.006) The median value of scWAT SWS was 1,5 m/s (range; 0.9-3.8), 1.23 m/s (range; 0.7-3.1) for leans and overweight, respectively. In leans, no significant difference was found between boys and girls for scWAT SWS (p=0.094). In overweight, a significant difference was found for scWAT SWS between boys and girls (p=0.022). The scWAT stiffness is lower in overweight than leans. Gender has a pivotal role in scWAT stiffness. If supported with future long-time follow-up studies, p-SWE may be compatible with assessing subcutaneous adipose tissue changes related to obesity and metabolic complications in childhood and adolescence.
Role of the midwife in perinatal mourning in the current context of a pandemic. Clinical case
Authors: Rodríguez Villalón Marta , García Quirós Paula , Núñez García Ana , Merino Martín Sandra , González Berrocal Paula
Published: April 2022

In 2019, the late fetal mortality rate in Spain was 3.11 deaths per thousand births. The outcome of perinatal and/or neonatal death is a devastating experience for both the mother and the family, thus, providing high quality bereavement care has been shown to reduce emotional, psychological and social negative effects for parents. Many healthcare professionals find it difficult to handle these situations. In addition, the current SARS-CoV-2 social health crisis further complicates the quality of care that could be provided in these situations. With the presentation of this clinical case we want to highlight the important role of the midwife in the care of perinatal grief in the context of the pandemic situation. The data collected in physical examinations and assessments are presented according to the Virginia Henderson model, and a complete care plan is developed. It is important to create strategies with an interdisciplinary team to facilitate coping with grief. Interventions related to memory creation emerge as important elements in parents' experiences, so we should give them greater emphasis. Quality health care must be achieved to help solve the grieving process, and midwives must be one of the reference professionals for this. Finally, more research studies are considered necessary, taking into account which has been mentioned before and continuing with the development and implementation of guidelines in Spanish hospitals.

Published: April 2022

Objective: Analyze the diagnostic precision of the qSOFA scale against the SIRS criteria in emergency triage to identify patients with suspected sepsis. Method: Ambispective cohort study in the emergency room of the Costa del Sol Hospital. The study subjects were older than 14 years who attended with suspected or confirmed infection in the years 2017 and 2019. Sociodemographic variables were evaluated, the physiological variables of qSOFA and SIRS, level of triage, attention circuit, activation of sepsis code. Descriptive analysis was performed in a segmented manner according to the year of study. The statistics of the diagnostic tests were described to know the prognostic capacity of qSOFA. Results: 42 patients were recruited in 2017 and 41 in 2019.The mean age of the patients exceeded 75 years on average in both periods. When analyzing the diagnostic effort for activating the sepsis code, 2 patients (4.8%) had completed all the parameters contemplated by SIRS and 1 (2.4%) with qSOFA (p = 1) for each year of study. Conclusions: The lack of records of physiological parameters that contemplate the study scales has made it difficult to determine the diagnostic validity of qSOFA in hospital emergencies. However, the experience and clinical judgment of the triage nurse has contributed to the fact that all the patients studied were correctly classified according to the level of priority and care circuit, guaranteeing early care in sepsis.

Vi rút hợp bào hô hấp (RSV) là tác nhân chính gây nên các bệnh đường hô hấp dưới ở cả trẻ nhỏ và người lớn tuổi. Mặc dù RSV đã được phân lập lần đầu tiên từ năm 1955 nhưng đến nay vẫn chưa có vắc xin hiệu quả. Có rất nhiều các nghiên cứu về RSV đã được thực hiện để phát triển vắc xin ở trẻ nhỏ, phụ nữ mang thai, người lớn tuổi và người trưởng thành nhưng những loại vắc xin này vẫn chưa được cấp phép để sản xuất. Sự đa dạng di truyền, mang đặc tính theo từng khu vực địa lý, trong khoảng thời gian cụ thể, được đặc trưng bởi tính theo mùa riêng biệt, phụ thuộc vào độ ẩm và khả năng tái nhiễm là những yếu tố khiến RSV có mô hình dịch tễ học phân tử phức tạp. Bài viết này, tổng hợp các nghiên cứu được thực hiện gần đây cả trên thế giới và Việt Nam nhằm đưa ra những xu hướng và triển vọng phát triển trong tương lai của nghiên cứu RSV.

MILLENNIALS’ PERCEPTION TOWARDS REFERENCES OF “PEREMPUAN” IN GREAT DICTIONARY OF INDONESIAN LANGUAGE (KBBI)
Authors: Ratna Wijaya Ayudhia
Published: April 2022

This study is a mini case study focusing on millennials’ perception towards the references of “perempuan” or “woman” from Kamus Besar Bahasa Indonesia (KBBI) or Great Dictionary of the Indonesian Language. This research applies a quantitative method with description approach. The researcher collected the data through an online questionnaire which involved 116 respondents aged from 16-30 years old. The researcher asked the respondents to fill the questionnaire focusing on showing their tendency to the gender-based references and showing their perception to the definition in the dictionary. In findings, the respondents correlate matriarchal domestic responsibility, such as “raising child”, in an even view between man and woman. On the other hand, the participants of the research had a growing neutrality over the previously male dominated terms, such as “hardworking” and “boss”. Despite the progressivity, millennials still have a high tendency of maintaining derogatory references against woman, such as “prostitute” and “slut”. The study also shows that 65.5% of respondents disagree with the definition of “perempuan” in KBBI. They challenge the definition under the idea of gender equality. Millennials’ perspective of the language differs from maintaining the definition to shifting the conservative image of woman to more progressive. Meanwhile, the other 34.5% agree with the definition in KBBI. They highlighted the relevancy of the definition with the traditional views of women focusing on women’s biological features.
Radiative impact of improved global parameterisations of oceanic dry deposition of ozone and lightning-generated NOx
Authors: Luhar Ashok K. , Galbally Ian E. , Woodhouse Matthew T.
Published: April 2022

Abstract. We investigate the impact of recent process-based and empirical improvements to oceanic ozone dry deposition parameterisation and lightning-generated NOx (LNOx) parameterisation on radiative fluxes by conducting a 5-year simulation of the global ACCESS-UKCA chemistry-climate model with radiative feedbacks of ozone and methane included. Both parameterisations increase the global net downward top-of-the-atmosphere (TOA) radiative flux, akin to instantaneous radiative forcing, compared to the base parameterisations. The dry deposition improvement results in a relatively small increase of 4.3 mW m-2 in the net downward TOA radiative flux. But this increases to 86 mW m-2 when the improved LNOx parameterisation (which increases the LNOx production from 4.8 to 6.9 Tg N yr-1) is also used. For comparison, this estimated difference in the radiative flux is equivalent to ~18 % of the anthropogenic effective radiative forcing (ERF) due to ozone over the years 1750–2019 reported by the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Other global changes from the use of the two parameterisations include an increase in the downward longwave radiation and a decrease in the downward shortwave radiation at the Earth’s surface, and a decrease of 0.64 years in the methane lifetime against loss due to the hydroxyl radical, with changes being larger in magnitude in the tropics. Although the total global LNOx production may be the same, how LNOx is distributed spatially makes a difference to radiative transfer. The changes in radiation components and methane lifetime per unit change in LNOx and column ozone are also calculated. We estimate that the uncertainty range in the net downward TOA radiation due to reported uncertainty range in global estimates of LNOx could be as much as 238 mW m-2. LNOx has a significant influence on the atmospheric lifetime of CH4, and the value of LNOx used within a model will influence the ERF and global warming potential of anthropogenic methane.
Interactions between thresholds and spatial discretizations of snow: insights from wolverine habitat assessments in the Colorado Rocky Mountains
Authors: Pflug Justin M. , Fang Yiwen , Margulis Steven A. , Livneh Ben
Published: April 2022

Abstract. Thresholds can be used to interpret environmental data in a way that is easily communicated and useful for decision making purposes. However, thresholds are often developed for specific data products and time periods, changing findings when the same threshold is applied to datasets or periods with different characteristics. Here, we test the impact of different spatial discretizations of snow on annual estimates of wolverine habitat in the Colorado Rocky Mountains, defined using a snow water equivalent (SWE) threshold (0.20 m) and threshold date (15 May) from previous habitat assessments. Annual wolverine habitable area (WHA) was thresholded from a 36-year (1985–2020) snow reanalysis at three different spatial discretizations: 1) 480 m grid cells, 2) 90 m grid cells, and 3) 480 m grid cells with implicit representations of subgrid snow spatial heterogeneity. Relative to the 480 m grid cells, 90 m grid cells resolved shallower snow deposits on slopes between 3050 and 3350 m elevation, decreasing WHA by 10 %, on average. In years with warmer and/or drier winters, grid cells with subgrid representations of snow heterogeneity increased the prevalence of 15 May snow deposits that exceeded the 0.20 m SWE threshold, even within grid cells where mean SWE was less than the threshold. These simulations increased WHA by upwards of 30 % in low snow years, as compared to simulations without subgrid snow heterogeneity. Despite WHA sensitivity to different snow spatial discretizations, WHA was controlled more by annual variations in winter precipitation and temperature. However, small changes to the SWE threshold (± 0.07 m) and threshold date (± 2 weeks) also affected WHA by as much as 82 %. Across these threshold ranges, WHA was approximately 18 % more sensitive to the SWE threshold than the threshold date. However, the sensitivity to the threshold date was larger in years with late spring snowfall, when WHA depended greatly on whether the date SWE was thresholded was before, during, or after spring snow accumulation. Our results demonstrate that snow thresholds are useful but may not always provide a complete picture of the annual variability in snow-adapted wildlife habitat. Studies thresholding spatiotemporal datasets could be improved by including 1) information about the fidelity of thresholds across multiple spatial discretizations, and 2) uncertainties related to ranges of realistic thresholds.
Surface circulation properties in the Eastern Mediterranean emphasized using machine learning methods

Published: April 2022

Abstract. The Eastern Mediterranean surface circulation is highly energetic, composed of structures interacting stochastically. However, some main features are still debated, and the behavior of some fine-scale dynamics and their role in shaping the general circulation is yet unknown. In the following paper, we use an unsupervised neural network clustering method to analyze the long-term variability of the different mesoscale structures. We decompose 26 years of altimetric data into clusters reflecting different circulation patterns of weak and strong flows with either strain or vortex-dominated velocities. The vortex-dominated cluster is more persistent in the western part of the basin, which is more active than the eastern part due to the strong flow along the coast, interacting with the extended bathymetry and engendering continuous instabilities. The cluster that reflects a weak flow dominated the middle of the basin, including the Mid-Mediterranean Jet (MMJ) pathway. However, the temporal analysis shows a frequent and intermittent occurrence of a strong flow in the middle of the basin, which could explain the previous contradictory assessment of MMJ existence using in-situ observations. Moreover, we prove that the Levantine Sea is becoming more and more energetic as the activity of the main mesoscale features is showing a positive trend.
Decreased virtual water outflows from the Yellow River basin are increasingly critical to China

Published: April 2022

Abstract. Water scarcity is an emerging threat to food security and socio-economic prosperity, and it is crucial to assess crop production response to water scarcity in large river basins.
The water footprint, which considers water use in supply chains, provides a powerful tool for assessing the contributions of water resources within a certain region by tracking the volume and structure of virtual water flows.
In this study of the structure of the water footprint network from a complexity perspective, we reassessed the significance of water resources for crop services in a large river basin with a severe water shortage – the Yellow River basin (YRB) of China.
The temporal increase of the complexity index indicated that the virtual water outflows (VWFs) from the YRB were becoming increasingly critical to China; i.e. the ability of YRB to produce crops boosted the difficulty of its water being replaced by water exporting from other basins.
Decomposition of complexity suggested that during the 1980s to 2000s, the temporally increased complexity was due mainly to the lack of competitors and the increasing uniqueness of crops supporting VWFs.
This complexity deeply embedded the YRB into the footprints of a water network that facilitated further development with constrained water resources. Still, it also reinforced reliance from other regions on YRB's scarce water.
Based on this analysis, we suggest that resource regulation should be carried out appropriately to ensure ecological sustainability and high-quality development of river basins.
Lower Jurassic calcareous nannofossil taxonomy revisited according to the Neuquén Basin (Argentina) record
Authors: Chaumeil Rodríguez Micaela , Mattioli Emanuela , Pérez Panera Juan Pablo
Published: April 2022

Abstract. Standard Early Jurassic biostratigraphic studies were performed in the boreal and Tethys realms (western Europe and northern Africa), and biozonations from these areas are the most accurate of the world. Comparatively, investigations in the Pacific realm are scarce, and, in Argentina, they are limited to contributions based on oil-industry subsurface and outcrop reports for the Los Molles Formation. A focused systematic analysis was not previously addressed in the area. The Neuquén Basin in west–central Argentina offers a unique opportunity to study the Early Jurassic calcareous nannofossil history in the south-eastern Pacific Ocean. Calcareous nannofossil assemblages from El Matuasto I section (Los Molles Formation) represent one of the earliest records for the Early Jurassic in the Neuquén Basin and one of the few for the eastern Pacific realm. A detailed systematic analysis allowed the recognition of major bioevents and a comparison with worldwide associations and biostratigraphic schemes. A thorough taxonomic discussion of the Early Jurassic nannofossil species of the Neuquén Basin is presented for the first time. Herein, the taxonomic features of coccoliths recorded in the Neuquén Basin are settled. The age of the calcareous nannofossil assemblages recorded in El Matuasto I is early–late Pliensbachian, covering the NJT4a to NJT4c subzones. Similarities between the Neuquén Basin and localities from the proto-Atlantic region suggest an effective connection between the Pacific and Tethyan basins during the Pliensbachian.

Published: April 2022

Objectives: This article presents a multiyear pilot study delineating practical challenges, solutions, and lessons learned from Wikipedia editing experiences with first-year medical students at the John A. Burns School of Medicine at the University of Hawaiʻi at Mānoa. The purpose of our project was to determine the feasibility and effectiveness of Wikipedia editing to improve information literacy and lifelong learning skills and to investigate aspects of social responsibility in first-year medical students.
Methods: Lessons were provided through a combination of in-person and online instruction via the WikiEdu learning management system (LMS). Students next selected a health-related Wikipedia article to edit. After the editing experience, structural completeness data were collected from the WikiEdu LMS. Feedback was collected via an anonymous retrospective pre-post survey to assess the students’ attitudes toward their perceived information literacy skills and the social responsibility of improving Wikipedia articles. Nonparametric tests were conducted to compare pre versus post outcomes.
Results: Fifty-seven (79%) participants in the 2018 cohort and forty-nine (64%) participants in the 2019 cohort completed the retrospective pre-post survey. In both cohorts, respondents showed statistically significant increases (p<.05) in self-rating of all ten domains of information literacy and social responsibility after completing the program.
Conclusions: This study showed that medical students are competent editors of Wikipedia and that their contributions improve both the quality of the articles and their own perceived information literacy. Additionally, editing medicine-related articles provides an opportunity to build students’ social responsibility by improving content on an open platform that reaches millions each day.
Health sciences librarians of African heritage: an earnest entreaty for research
Authors: Fikar Charles Raymond , Hallas Barbara

In view of recent discussions of diversity in library work, it would seem prudent to have a good understanding of basic facts and considered opinions of health sciences librarians of African heritage concerning their career experiences, opportunities for advancement, perceptions of negative behavior in the library, experiences of bias and discrimination in the library, existence of special information needs of patrons of African heritage, and interactions with non-African-heritage medical librarians and staff. Since there is a dearth of literature and research on these topics, this commentary will attempt to stimulate and encourage such work by providing a brief summary of currently available literature and research and providing some ideas for future academic endeavors.

Start Fast, Swim Faster, Turn Fastest: Section Analyses and Normative Data for Individual Medley
Authors: Born Dennis-Peter , Romann Michael , Stöggl Thomas
Published: April 2022

The aims of the study were to provide benchmarks and normative data for 100 m, 200 m, and 400 m short-course individual medley (IM) races, investigate differences between the various swimming strokes and turns involved in IM, and quantify the effect and contribution of various race sections on swimming performance. All IM races (n = 320) at the 2019 European Short-Course Swimming Championships were video monitored and digitized with interrater reliability described by a mean intra-class correlation coefficient of 0.968. Normative data were provided for the eight finalists of each event (FINA points = 886 ± 37) and the eight slowest swimmers from each event (FINA points = 688 ± 53). Contribution and effects of race sections on swimming performance were investigated using stepwise regression analysis based on all races of each event. Regression analysis explained 97-100% of total variance in race time and revealed turn time (β ≥ 0.53) as distinguishing factor in short-course IM races in addition to swim velocity (β ≥ -0.28). Start time only affected 100 m (β ≥ 0.14) and 200 m (β ≥ 0.04) events. Fastest turn times were found for the butterfly/backstroke turn. Breaststroke showed slowest swim velocities and no difference between fastest and slowest 100 m IM swimmers. Therefore, breaststroke may provide largest potential for future development in IM race times. Correlation analyses revealed that distance per stroke (r ≥ -0.39, P < 0.05) rather than stroke rate (r ≤ -0.18, P > 0.05) is a performance indicator and may be used by coaches and performance analysts to evaluate stroke mechanics in male IM swimmers despite its more complex assessment. Performance analysts, coaches, and swimmers may use the present normative data to establish minimal and maximal requirements for European Championship participation and to create specific drills in practice.

A Guided Mutation Grey Wolf Optimizer Algorithm Integrating Flower Pollination Mechanism
Authors: Jing-Sen Liu Jing-Sen Liu , Jing-Sen Liu Qing-Qing Liu , Qing-Qing Liu Fang Zuo
Published: April 2022

The basic Grey Wolf Optimizer (GWO) has some shortcomings, for example, the convergence speed is slow, it is easy to fall into local extremum, and high-dimensional optimization ability is poor and so on. In response to these shortcomings, an improved grey wolf algorithm which combines flower pollination mechanism, teaching mechanism and polynomial variation is proposed in this study. The flower pollination mechanism is integrated with GWO algorithm, Levy distribution is introduced into the global search of grey wolf population. And the double random mechanism is added in the local search, for these improvements, this algorithm’s overall optimization performance is improved. The teaching mechanism is added to wolf to improve the algorithm’s convergence speed. Polynomial mutation is applied to the individuals with poor optimization effect to improve the algorithm’s accuracy and its ability to jump out of local extremum. Theoretical analysis shows that the time complexity of the improved algorithm is the same as that of the basic algorithm. The test results of five representative comparison algorithms on multiple different characteristics and different dimensions of CEC2017 benchmark functions and two classical engineering problems show that FMGWO algorithm has high optimization accuracy, convergence speed and solution stability. Therefore, it has obvious advantages in global optimization.

Published: April 2022

The text filtering of traditional anti spam system mainly focuses on keyword matching and text fingerprint analysis, which is difficult to accurately identify and classify spam. Therefore, an integrated learning algorithm based on stackin g is proposed in this paper. Firstly, the algorithm takes the manually marked text data of various categories as samples, uses TF-IDF algorithm to train the word vector space model, then selects linear SVC, xgboost and logistic regression algorithm to structure the base classifier, uses random forest algorithm to structure the meta classifier, and combines the stacking ensemble learning algorithm to structure the classification model. It achieves the function of dividing e-mail into five categories: illegal, advertisement, news, bill and recruitment. From the simulation results, the AUC values of the stacking integrated learning classification algorithm for each category are 0.92, 0.95, 1.00, 0.93 and 0.97 respectively, and the AP values are 0.86, 0.88, 1.00, 0.88 and 0.94 respectively, which realizes the high performance and high precision of text classification.

 
Named Entity Recognition Model Based on TextCNN-BiLSTM-CRF with Chinese Text Classification
Authors: Ji-Ru Zhang Ji-Ru Zhang , Ji-Ru Zhang Bo He
Published: April 2022

The traditional Chinese Named Entity Recognition (NER) method is difficult to define the entity category of the word according to the specific language environment, and the category is ambiguous, so it is difficult to accurately identify the entity. Named entity recognition based on deep learning can find entity categories in text, so it has received widespread attention. On the basis of the neural network model, this paper proposes a model based on TextCNN-BiLSTM-CRF and text classification (TextCNN-BiLSTM-TC-CRF) for Chinese NER. First, the TextCNN model is used to extract the word vector information of the text data; secondly, bidirectional LSTM is used the model extracts the contextual features of the text; then the neural network model is used to automatically extract the word features and the global features of the text for text classification; finally, the text sequence labeling and entity recognition are performed. Experiments verify that on a large-scale Chinese NER data set, the entity recognition model proposed in this paper has better evaluation indicators than other algorithms, with an F1 score of 98.7%.

The current knowledge mapping relationship optimization methods cannot obtain high-precision information. An optimization method of knowledge mapping relationship based on improved ant colony algorithm is proposed. The high-precision information of the network is obtained by using the cyclic network. The SGP problem is used to replace the optimization problem of the knowledge map relationship. The optimization objective function of the knowledge map relationship is constructed and solved by the improved ant colony algorithm. The optimization of the knowledge map relationship is realized. Experimental results show that the proposed method has high average accuracy, high knowledge accuracy and high knowledge coverage.

In order to solve the problems of fuzzy image, different measuring range and recognition accuracy of pointer instrument in the process of power inspection, propose a pointer-type instrument recognition method based on Yolov3. Firstly, super-resolution technology is introduced to reconstruct the instrument image. Then, a combined Yolov3 and OCR- based dial feature extraction method is used to detect the dial in the instrument image, effectively extract the digital features in the region, and recognize the instrument by combining the digital features pointer-type angle. Next, to solve the instrument image’s fuzzy problem, a super-resolution image reconstruction technology is designed to reconstruct the fuzzy instrument image and get a clear instrument image. Finally, a method based on a Yolov3 and OCR combination is proposed to detect the instrument image and recognize the digital features of the dial to target the insufficient use of dial features. Comparison of the effect of traditional machine learning algorithm and Canny edge detection in the pointer-type instrument image recognition shows that the accuracy and practicability of this method have been significantly improved in the recognition of pointer-type instruments in complex environment images.
