Published: February 2021

BACKGROUND: Platelets play a key role in tumor progression and metastasis. C-type lectin-like receptor 2 (CLEC-2) is the receptor expressed on platelets and the marker of platelet activation. OBJECTIVE: This study aims to determine whether soluble CLEC-2 levels differ between patients with benign colorectal polyps and those with colorectal cancer (CRC). METHODS: We measured plasma soluble CLEC-2 by enzyme-linked immunosorbent assay in 150 patients with colorectal polyps, 150 CRC patients without metastasis, 150 CRC liver metastasis, and 150 control subjects. RESULTS: The CRC patients had higher soluble CLEC-2 levels than patients with colorectal polyps (p< 0.001). Moreover, CRC patients with liver metastases displayed higher CLEC-2 levels than those in CRC patients without metastases (p< 0.001). In the CRC patients, CLEC-2 levels were correlated with lymph node metastasis and advanced stage. In the patients with polyps, there was a significant difference in CLEC-2 levels among patients with hyperplastic polyp, sessile serrated adenoma, and traditional serrated adenoma (p< 0.001). The ROC curve analysis revealed CLEC-2 had an optimal sensitivity of 77.3% and specificity of 94.6% for the screening of CRC, and sensitivity of 71.0% and specificity of 76.7% for the differential diagnosis of colorectal polyps and CRC. CONCLUSIONS: CRC patients have higher CLEC-2 levels than patients with colorectal polyps and healthy controls. Moreover, there is a significant difference in CLEC-2 levels among polyp subtypes. Further research is warranted.

Published: February 2021

Energy consumption reduction has been an increasing trend in machine learning over the past few years due to its socio-ecological importance. In new challenging areas such as edge computing, energy consumption and predictive accuracy are key variables during algorithm design and implementation. State-of-the-art ensemble stream mining algorithms are able to create highly accurate predictions at a substantial energy cost. This paper introduces the nmin adaptation method to ensembles of Hoeffding tree algorithms, to further reduce their energy consumption without sacrificing accuracy. We also present extensive theoretical energy models of such algorithms, detailing their energy patterns and how nmin adaptation affects their energy consumption. We have evaluated the energy efficiency and accuracy of the nmin adaptation method on five different ensembles of Hoeffding trees under 11 publicly available datasets. The results show that we are able to reduce the energy consumption significantly, by 21% on average, affecting accuracy by less than one percent on average.
Using the beta distribution technique to detect attacked items from collaborative filtering
Authors: Hsu Ping-Yu , Chung Jui-Yi , Liu Yu-Chin
Published: February 2021

A recommendation system is based on the user and the items, providing appropriate items to the user and effectively helping the user to find items that may be of interest. The most commonly used recommendation method is collaborative filtering. However, in this case, the recommendation system will be injected with false data to create false ratings to push or nuke specific items. This will affect the user’s trust in the recommendation system. After all, it is important that the recommendation system provides a trusted recommendation item. Therefore, there are many algorithms for detecting attacks. In this article, it proposes a method to detect attacks based on the beta distribution. Different researchers in the past assumed that the attacker only attacked one target item in the user data. This research simulated an attacker attacking multiple target items in the experiment. The result showed a detection rate of more than 80%, and the false rate was within 16%.
Hierarchical features-based targeted aspect extraction from online reviews
Authors: He Jin , Li Lei , Wang Yan , Wu Xindong
Published: February 2021

With the prevalence of online review websites, large-scale data promote the necessity of focused analysis. This task aims to capture the information that is highly relevant to a specific aspect. However, the broad scope of the aspects of the various products makes this task overarching but challenging. A commonly used solution is to modify the topic models with additional information to capture the features for a specific aspect (referred to as a targeted aspect). However, the existing topic models, either perform the full analysis to capture features as many as possible or estimate the similarity to capture features as coherent as possible, overlook the fine-grained semantic relations between the features, resulting in the captured features coarse and confusing. In this paper, we propose a novel Hierarchical Features-based Topic Model (HFTM) to extract targeted aspects from online reviews, then to capture the aspect-specific features. Specifically, our model can not only capture the direct features posing target-to-feature semantics but also capture the latent features posing feature-to-feature semantics. The experiments conducted on real-world datasets demonstrate that HFTMl outperforms the state-of-the-art baselines in terms of both aspect extraction and document classification.
Real-time adaptive fuzzy density clustering for multi-target data association
Authors: Nazari Mousa , Pashazadeh Saeid
Published: February 2021

The problem of data association for tracking multiple targets based on using the ship-borne radar is addressed in this study. A robust fuzzy density clustering algorithm is proposed, that contains three steps. At first, a customized form of adaptive density clustering is used to determine valid measurements for each target’s state. In the second step, the degree of fuzzy membership for each valid measurement is determined based on the maximum entropy approach. At the final step, the measurements with a maximum degree of membership are used for updating the position of the targets. The proposed approach does not require gating techniques and led to the reduction of steps in comparison with other data association methods. In addition, the effect of ship movement in the performance of the tracking filter, based on the adaptive extended Kalman filter (AEKF) was studied. The efficiency and effectiveness of the proposed algorithm are compared with the nearest neighbor (NN) with Mahalanobis distance and Fuzzy nearest neighbor (FNN) methods. The results demonstrate the main advantages of the proposed algorithm, including its simplicity and suitability for real-time target tracking in cluttered environments.
Classification from positive and unlabeled data based on likelihood invariance for measurement
Authors: Yoshida Takeshi , Washio Takashi , Ohshiro Takahito , Taniguchi Masateru
Published: February 2021

We propose novel approaches for classification from positive and unlabeled data (PUC) based on maximum likelihood principle. These are particularly suited to measurement tasks in which the class prior of the target object in each measurement is unknown and significantly different from the class prior used for training, while the likelihood function representing the observation process is invariant over the training and measurement stages. Our PUCs effectively work without estimating the class priors of the unlabeled objects. First, we present a PUC approach called Naive Likelihood PUC (NL-PUC) using the maximum likelihood principle in a nontrivial but rather straightforward manner. The extended version called Enhanced Likelihood PUC (EL-PUC) employs an algorithm iteratively improving the likelihood estimation of the positive class. This is advantageous when the availability of the labeled positive data is limited. These characteristics are demonstrated both theoretically and experimentally. Moreover, the practicality of our PUCs is demonstrated in a real application to single molecule measurement.
A citation recommendation method based on context correlation
Authors: Zhao Weidong , Yu Zhaoxin , Wu Ran
Published: February 2021

Researchers need to formulate their achievements as research papers. Representative references are essential to high-quality papers. Academic citation recommendation refers to providing the recommendation of citations for the author of papers when they write. With the help of citation recommendation, researchers can improve the efficiency of writing academic papers and reduce the omission of important related literature. To achieve this goal, some methods were proposed. Many of them used citation networks to learn the representation of papers and chose references, they tended to ignore the content properties of papers. There are also some methods used partial properties to recommend citation. But their performance can be further improved. In this paper, we propose a citation recommendation method based on context correlation. We use two neural network models to learn the representations of papers and their references, then calculate the context similarity of them. Besides, we also introduce the publishing time and authority of papers, two key properties of papers for citation evaluation. In the experiment section, we compare our method with other methods and evaluate the performance of different properties choice in our method, it shows that our method outperforms some baselines and the combination of the dimensions including time, authority and context performs better.

Authors: Shiekh Suhail Ismail , Cadogan Sharon Louise , Lin Liang-Yu , Mathur Rohini , Smeeth Liam , Warren-Gash Charlotte
Published: February 2021

Background: Globally around 50 million people have dementia. Risk factors for dementia such as hypertension and diabetes are more common in Black, Asian, and other ethnic minorities. There are also marked ethnic inequalities in care seeking, likelihood of diagnosis, and uptake of treatments for dementia. Nevertheless, ethnic differences in dementia incidence and prevalence remain under-explored. Objective: To examine published peer-reviewed observational studies comparing age-specific or age-adjusted incidence or prevalence rates of dementia between at least two ethnic groups. Methods: We searched seven databases on 1 September 2019 using search terms for ethnicity, dementia, and incidence or prevalence. We included population-based studies comparing incidence or prevalence of dementia after accounting for age of at least two ethnic groups in adults aged 18 or more. Meta-analysis was conducted for eligible ethnic comparisons. Results: We included 12 cohort studies and seven cross-sectional studies. Thirteen were from the US, and two studies each from the UK, Singapore, and Xinjiang Uyghur Autonomous Region in China. The pooled risk ratio for dementia incidence obtained from four studies comparing Black and White ethnic groups was 1.33 (95% CI 1.07–1.65; I-squared = 58.0%). The pooled risk ratio for dementia incidence comparing the Asian and White ethnic groups was 0.86 (95% CI 0.728–1.01; I-squared = 43.9%). There was no difference in the incidence of dementia for Latino ethnic group compared to the White ethnic group. Conclusion: Evidence to date suggest there are ethnic differences in risk of dementia. Better understanding of the drivers of these differences may inform efforts to prevent or treat dementia.
Comparison of the Caregiving Experience of Grief, Burden, and Quality of Life in Dementia with Lewy Bodies, Alzheimer’s Disease, and Parkinson’s Disease Dementia

Published: February 2021

Background: Caregivers of persons living with Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), and Parkinson’s disease dementia (PDD) are faced with numerous challenges. However, little is known about the caregiving experience across different dementias. Objective: The aims of this cross-sectional study were to examine the differences in the caregiver experience between DLB, PDD, and AD. Methods: Respondents were caregivers (N = 515; 384 DLB, 69 AD, 62 PDD) who completed a 230-question survey including sociodemographics, disease severity, neuropsychiatric symptoms, and measures of grief, burden, depression, quality of life, social support, well-being, care confidence, and mastery/self-efficacy. Results: There were no differences in caregiver age, sex, race, or education, or in the distribution of disease severity between diagnostic groups. Constructs were highly intercorrelated with positive attributes (caregiver QoL, care recipient QoL, social support, well-being, mastery and care confidence) being inversely correlated with negative attributes (burden, grief, and depression). Across dementia etiologies, no differences were reported for quality of life, social support, depression, well-being, psychological well-being, mastery, care confidence, burden or grief. Instead, we found that the caregiver’s experience was dependent on caregiver characteristics, person living with dementia characteristics and their most disturbing symptom, with behavior, personality changes, and sleep having the greatest effect on constructs. Conclusion: Caregiver ratings of psychosocial constructs may be more dependent on care recipient-caregiver dyad characteristics and the current symptoms than the underlying cause of those symptoms. Interventions to improve the caregiving experience should be developed to address specific psychosocial constructs rather than focusing on disease etiology or stage.

Recent year development in each field and area progresses rapidly. For one particular product or service, people have multiple alternative. However, to choose best alternative is most difficult task that most of person facing. VIKOR method is most used approach for choosing best alternative based on different criteria but legging in precision. In this paper, we propose modifier VIKOR with Fuzzy logic integration approach that deal with multiple criteria while making decision as well as integratestriangular fuzzy numbers (TFN) for computing criteria values and weight importance in the processing selecting best alternative. Firstly, positive best points and negative best points were demarcated in a triangular fuzzy number evaluation matrix. Secondly, we analyze the requirements and properties of the VIKOR-based triangular fuzzy number operation rule. Thirdly, an extension of VIKOR method was proposed for comprehensive evaluation of schemes to reduce the information loss arising from defuzzification of triangular fuzzy numbers; Finally, an example demonstrate the efficiency and viability of the method. In conclusion, the proposed method solves the difficulties that subtractive computation between two triple numbers violate the arithmetic regulation, and propose a reasonable procedure according to decision making problems with triple numbers.

Authors: Wang Hongyi
Published: February 2021

The ultimate goal of listed companies is to maximize shareholders’ wealth. With the increasingly fierce market competition, enterprise managers are constantly exploring the key indicators that have an important impact on the financial performance (FP) of enterprises, and achieve the expected FP of shareholders by improving these key indicators. On the basis of the existing enterprise performance measurement system and index research, through expert scoring to determine the secondary indicators, this paper selects 87 small and medium-sized board listed companies which officially announced the implementation of equity incentive from 2009 to 2012 as the sample, takes the financial information disclosed in 2013 as the empirical data, and analyzes the traditional multiple linear regression analysis (MLR) When dealing with big data, especially the data with hierarchical structure, this paper proposes a partial regression coefficient calculation model based on hierarchical data, constructs a multiple nonlinear regression model, and concludes through empirical analysis that there is a nonlinear correlation between equity incentive ratio and corporate performance, and that there is an interval effect between equity incentive ratio and corporate performance. We also present Fuzzy based financial performance prediction of listed companies. Finally, we demonstrate Comparative analysis for financial prediction in term of accuracy between multiple regression model and fuzzy logic system and result deduce that fuzzy logic gives better accuracy than regression model.

Authors: Zhao Nan , Wang Yubo , Tang Xiaoke , Gan Jie , Zhao Xu , Zhang Yubing
Published: February 2021

Due to the influence of filters and multipath channels, the received signal of the current symbol will be affected by the interference of the previous symbol and the next symbol, the interference will reduce the performance of channel estimation, especially when the SF is relatively low, which will affect the system throughput rate. In this paper, based on BPSK chirp spread spectrum modulation system, we first describe the channel estimation of matched filtering and FFT, and derive the influence of ISI on the channel estimation of the current pilot symbol. Then we proposed the improved channel estimation based on the estimated time delay spread and transmitted signals. Finally, we simulate the MSE performance of channel estimation under different channels and different transmitted signals. The simulation results show that the MSE performance of the improved channel estimation can be improved under different channel when the SF is low, and higher throughput can be obtained.
Application of fusion 2D lidar and binocular vision in robot locating obstacles
Authors: Shao Weiwei , Zhang Handong , Wu Yuxiu , Sheng Na
Published: February 2021

If robot uses 2D lidar or binocular camera to locate obstacles, there will be some problems such as missing obstacle information or inaccurate obstacle locating, which will affect the normal work of the robot. In order to obtain accurate 3D obstacle information, this paper proposes an algorithm for fusing 2D lidar and binocular vision to complete the obstacle location. In this paper, the depth value of the 2D lidar point cloud is used as a benchmark. By fitting the error equation of the binocular camera point cloud depth value, the depth value of the camera point cloud is modified to obtain an accurate 3D camera point cloud, thereby obtaining an accurate 3D obstacle information. Many experiments have proved that the fusion algorithm of 2D lidar and binocular vision can obtain accurate 3D obstacle information. The method of fusion 2D lidar and binocular vision can approximately achieve the measurement effect of 3D lidar, and the point cloud of obstacles is relatively dense, so the accurate 3D obstacle information can be obtained. This method can reduce the influence of single sensor on the robot locating obstacles, thus completing the accurate locating of obstacles, which is of certain significance to robot navigation.

We introduce rough approximations into basic algebras. After investigating elementary properties of the upper (lower) approximations in basic algebras and discussing the convexity of these two approximations in linearly ordered basic algebras, we generalize related results for MV-algebras, lattice ordered effect algebras, and orthomodular lattices to basic algebras. We also study the relationship between upper (lower) rough ideals of basic algebras and upper (lower) approximations of their homomorphic images.
Between Hospitality and Hostility: Public Attitudes and State Policies Toward Syrian Refugees in Turkey
Authors: Secen Sefa , Gurbuz Mustafa
Published: February 2021

This article provides an overview of the public attitudes and state policies toward Syrian refugees in Turkey between 2011 and 2020. Turkey’s policies toward refugees and the Syrian conflict have gradually changed over the course of the last nine years (2011–2020). Turkey’s legal approach to Syrian refugees has transformed from nonrecognition to recognition and from recognition to integration. Likewise, its military strategy has grown from one of limited engagement into one of active engagement in the face of ISIS attacks and YPG’s consolidation of power in northern Syria. Contrary to the generous policies adopted toward Syrian refugees during the early years of the Syrian civil war, a nativist turn and the weaponization of refugees against the European Union came to characterize the country’s approach in recent years as the country became more involved militarily in the Syrian conflict.

This paper discusses the clinical importance of the isolated single umbilical artery (iSUA). It was demonstrated that iSUA is an independent risk factor for perinatal death. The authors report that iSUA results in higher risk of the manual removal of the placenta, atonic post-partum hemorrhage, and postpartum uterus curettage. iSUA is closely associated with esophageal and anorectal atresia or stenosis and trisomy 13 and trisomy 18. Isolated iSUA (i.e., in the lack of fetal malformations) is associated with the Battledore placenta. It is also emphasized that iSUA fetus should be monitored using an ensemble of diagnostic techniques (ultrasound, Doppler, cardiotocography) for the early recognition of placental hypoperfusion, intrauterine growth restriction, and fetal acidosis. The authors postulate that a worsening of the cerebroplacental ratio or placental perfusion indices as well as abnormal cardiotocography are the indications to C-section in iSUA. In spontaneous delivery, the continuous electronic monitoring of fetal heart beat is recommended for the prompt diagnosis of its impairment, the prevention of maternal hemorrhages, and the detection of fetal abnormalities postnatally. The management of iSUA risk factors includes smoking cessation, the control of diabetes and hypertension.

Iron-deficiency anemia (IDA) is an acquired disease characterized by the reduced levels of iron in the serum, tissues, and bone marrow that mainly result from hemorrhages (e.g., nasal, gastrointestinal etc.). Women are at risk for IDA due to the physiological monthly loss of blood, childbearing, and breastfeeding but also due to various gynecological disorders leading to iron depletion and anemia. The paper describes the pathogenic mechanisms, diagnostic criteria, and clinical presentations of IDA and the potential consequences of iron overload. Considering a high medical and social importance of anemia in pregnancy, the data on IDA prevalence in this cohort as well as the potential complications both for the mother and the child are addressed. Current therapeutic approaches for anemia using peroral and parenteral iron preparations and their indications are highlighted. The prevention of iron deficiency and the effective options of its correction are viable tasks which allow for improving the health and quality of women’s life.

Published: February 2021

This paper discusses polycystic ovary syndrome (PCOS), a common endocrine disorder characterized by hirsutism, anovulation, and polycystic ovaries. Insulin resistance which is considered the major causative factor for both PCOS and metabolic syndrome is emphasized. The early diagnosis of metabolic disorders which increase the risk of cardiovascular complications and the complications of pregnancy (including gestational diabetes and hypertension which may result in preeclampsia and placental abruption) is of particular importance. The presence of metabolic syndrome in PCOS is associated with poor prognosis in terms of fertility and has a negative impact on the outcomes of in vitro fertilization in infertile women with PCOS. When describing treatment approaches, the role of metformin, inositol, folates, vitamin D, and statins in treating metabolic disorders in PCOS and metabolic syndrome, reducing the risks of cardiovascular complications, and realizing fertile function is highlighted. The course of PCOS is complicated by psychic disorders (i.e., depression, anxiety, bipolar disorder, or eating disorders) which are common in these women and should be considered when prescribing medications.

Published: February 2021

Aim: to assess the prevalence and presentations of anxiety in preschool children with attention deficit/hyperactivity disorder (ADHD). Patients and Methods: preschoolers (4–6 years) and their parents were enrolled. 30 children with ADHD and their parents were included in the study group and 15 healthy children and their parents were included in the control group. The study was performed in Moscow kindergartens. Clinical anamnestic, experimental psychological (Р. Temple, М. Dorkey, and Е.W. Amen anxiety test adapted by V.M. Astapov; “Fears in Houses” test modified by M.A. Panfilova; questionnaire for anxiety in children for a teacher and parents by G.P. Lavrent’eva and T.M. Titarenko), and statistical tests were applied. Results: in children with ADHD, a significantly higher level of anxiety was reported as demonstrated by Р. Temple, М. Dorkey, and Е.W. Amen anxiety test results (i.e., the test completed by children themselves). The percentage of children with 15 fears or more was significantly higher in the study group compared to the control group. Most preschoolers from both groups experience so-called age-related fears. In addition, age-inappropriate social fears (e.g., a fear of punishment or a fear of being late for kindergarten) were revealed in children with ADHD. These fears were much more common in the study group compared to the control group. Conclusions: our findings demonstrate a higher level of anxiety in children with ADHD compared to healthy children. Therefore, anxiety may be regarded as an ADHD-associated factor. In addition to typical age-related fears, children with ADHD experience so-called social fears. This phenomenon illustrates a fear of disapproval and punishment and a propensity for low self-esteem. KEYWORDS: attention deficit/hyperactivity disorder, anxiety disorders, preschoolers.

Published: February 2021

The important role of vitamins for bodily functions was described for the first time by Russian pediatrician N.I. Lunin as early as in 1880. Since then, doctors, biologists, researchers, and other experts have focused on the effects of vitamins on human body and their role in various processes. In 2017, the Union of Pediatricians of Russia has developed “National program of the optimization of vitamin and mineral supply of Russian children” based on the monitoring of child nutrition. Treatment of multivitamin deficiency involves additional intake of missing substances as well as the improvement of their absorption and their synthesis in human body. The vast majority of vitamin and mineral supplements contain daily-recommended amounts of essential vitamins and microelements. However, not all substances are completely absorbed since patients with multivitamin deficiency often have gut microbiome abnormalities resulting in poor availability of supplemented vitamins and minerals. This paper discusses the rationale of additional vitamins, their role in bodily functions, and signs of vitamin deficiency.

The Pecut kuda plant is one of the plants of the genus Stachytarpheta which is found in tropical regions, including Indonesia. In Indonesia this plant is found in East Kalimantan which grows wild. This study aims to determine the type of secondary metabolites and the level of toxicity of the leaves of horse whip (Stachytarpheta jamaicenesis (L.) Vahl). The research stages were sample drying, sample maceration, filtered, concentrated with a rotary evaporator, phytochemical and toxicity tests using linear regression values to determine the LC50 value with SAS probit analysis. Phytochemical test results showed that the pecut horse leaf extract in the n-hexane fraction contained flavonoids, quinones and steroids, the ethyl acetate fraction contained alkaloids, steroids, saponins, flavonoids and quinones and the methanol fraction contained phenolic flavonoids, quinones and saponins. The results of the toxicity test on Artemia salina L. shrimp larvae in the fraction of n-hexane, ethyl acetate and methanol obtained LC50 values of 0.036 ppm, 5.24 ppm and 29.51 ppm, respectively. Based on the LC50 value, it can be concluded that the three fractions are very toxic, but the most toxic is the n-hexane fraction (LC50 = 0.036 ppm).

ABSTRACTIndonesia is a country with geographical location where 4 large tectonic plates meet. Therefore, if a collision or frictionhits the country, it is vulnerable to earthquakes. This condition makes the buildings more vulnerable to earthquakes. The effect of earthquake force and the performance of the resulting structure will be different if the same load is applied to a regular building and to an irregular building. The method to calculate the effect of the earthquake on the analysis of high-rise building structures in this study used dynamic analysis with spectrum response referred to SNI 03-1726-2012 and 2013 ETABS software program assistance (13.1.1 build 1035). This study aimed to compare the performance of the structure based on the deflection value and the story drift limits in regular and irregular buildings. In this study, the response of structural performance on three building models was calculated with variations in horizontal structure irregularity and then the results were compared. In this research, the biggest deflection was resulted on the re-entrant corner irregularity model C in the x-direction of 7,219 mm and the y-direction of 4,244 mm. Based on the deflection value in the x-direction and y-direction on all building models, the story drift due to the effect of the earthquake plan was less than
Educación: Un estudio basado en el informe de la UNESCO sobre los cuatro pilares del conocimiento
Authors: Rodrigues Zuleide Blanco
Published: February 2021

Este trabajo toma como referencia la obra “Educación: Un tesoro para descubrir – Educação: Um Tesouro a Descobrir” de Jacques Delors, preparada para la UNESCO, sobre los cuatro pilares del conocimiento: aprender a saber, a hacer, a vivir juntos y a ser, ser una investigación bibliográfica. El problema que motivó este trabajo es mostrar que el profundo cambio de los marcos tradicionales de la existencia humana nos anteta el nuevo compromiso de entender mejor el otro ser social y el mundo que nos rodea. El objetivo general es sensibilizar a las personas vinculadas al proceso educativo para darse cuenta de que la práctica de la educación actual se basa en la opinión de que la persona humana se ocupa de factores externos, sin la debida instigación de la autonomía del razonamiento. Los pilares tienen objetivos específicos: llevar a las personas a lo largo de la vida a caminar por el camino del autoconocimiento, desarrollar la personalidad de manera integral; consolidar el espíritu de equipo, la creatividad y el respeto por las diferencias; despertar desde una edad temprana la conciencia de que una educación basada en los cuatro pilares del conocimiento formará los líderes del futuro. La conclusión que cierra la obra demuestra que la evolución actual de la sociedad, frente a la máquina de producción, está exigiendo nuevos proposituos de la absorción del conocimiento, la creación, la convivencia y la dimensión social en esta Era del Conocimiento.
