Ordering graphs with large eccentricity-based topological indices
Authors: Tang Yunfang , Qi Xuli 
Published: January 2021

AbstractFor a connected graph, the first Zagreb eccentricity index$\xi _{1}$ξ1is defined as the sum of the squares of the eccentricities of all vertices, and the second Zagreb eccentricity index$\xi _{2}$ξ2is defined as the sum of the products of the eccentricities of pairs of adjacent vertices. In this paper, we mainly present a different and universal approach to determine the upper bounds respectively on the Zagreb eccentricity indices of trees, unicyclic graphs and bicyclic graphs, and characterize these corresponding extremal graphs, which extend the ordering results of trees, unicyclic graphs and bicyclic graphs in (Du et al. in Croat. Chem. Acta 85:359–362, 2012; Qi et al. in Discrete Appl. Math. 233:166–174, 2017; Li and Zhang in Appl. Math. Comput. 352:180–187, 2019). Specifically, we determine then-vertex trees with thei-th largest indices$\xi _{1}$ξ1and$\xi _{2}$ξ2foriup to$\lfloor n/2+1 \rfloor $⌊n/2+1⌋compared with the first three largest results of$\xi _{1}$ξ1and$\xi _{2}$ξ2in (Du et al. in Croat. Chem. Acta 85:359–362, 2012), then-vertex unicyclic graphs with respectively thei-th and thej-th largest indices$\xi _{1}$ξ1and$\xi _{2}$ξ2foriup to$\lfloor n/2-1 \rfloor $⌊n/2−1⌋andjup to$\lfloor 2n/5+1 \rfloor $⌊2n/5+1⌋compared with respectively the first two and the first three largest results of$\xi _{1}$ξ1and$\xi _{2}$ξ2in (Qi et al. in Discrete Appl. Math. 233:166–174, 2017), and then-vertex bicyclic graphs with respectively thei-th and thej-th largest indices$\xi _{1}$ξ1and$\xi _{2}$ξ2foriup to$\lfloor n/2-2\rfloor $⌊n/2−2⌋andjup to$\lfloor 2n/15+1\rfloor $⌊2n/15+1⌋compared with the first two largest results of$\xi _{2}$ξ2in (Li and Zhang in Appl. Math. Comput. 352:180–187, 2019), where$n\ge 6$n≥6. More importantly, we propose two kinds of index functions for the eccentricity-based topological indices, which can yield more general extremal results simultaneously for some classes of indices. As applications, we obtain and extend some ordering results about the average eccentricity of bicyclic graphs, and the eccentric connectivity index of trees, unicyclic graphs and bicyclic graphs.
A q-Polak–Ribière–Polyak conjugate gradient algorithm for unconstrained optimization problems
Authors: Mishra Shashi Kant , Chakraborty Suvra Kanti , Samei Mohammad Esmael , Ram Bhagwat 
Published: January 2021

AbstractA Polak–Ribière–Polyak (PRP) algorithm is one of the oldest and popular conjugate gradient algorithms for solving nonlinear unconstrained optimization problems. In this paper, we present a q-variant of the PRP (q-PRP) method for which both the sufficient and conjugacy conditions are satisfied at every iteration. The proposed method is convergent globally with standard Wolfe conditions and strong Wolfe conditions. The numerical results show that the proposed method is promising for a set of given test problems with different starting points. Moreover, the method reduces to the classical PRP method as the parameter q approaches 1.
Weak and strong convergence of inertial algorithms for solving split common fixed point problems
Authors: Chen Hong-Yi 
Published: January 2021

AbstractIn this paper, we propose two iterative schemes for approximating solutions of split common fixed point problems in multiple linear operators case. The first algorithm implements the Krasnosel’skiĭ–Mann iteration with an inertial effect for which the weak convergence is established under mild assumptions. With the tool of nearly contractive mappings, we introduce a viscosity-type iteration which ensures strong convergence. We apply our results to solve a multiple split monotone variational inclusion problem. A numerical example is given to demonstrate the efficiency of the proposed algorithms.
Stochastically exponential synchronization for Markov jump neural networks with time-varying delays via event-triggered control scheme
Authors: Liu Xiaoman , Zhang Haiyang , Yang Jun , Chen Hao 
Published: January 2021

AbstractThis paper focuses on the stochastically exponential synchronization problem for one class of neural networks with time-varying delays (TDs) and Markov jump parameters (MJPs). To derive a tighter bound of reciprocally convex quadratic terms, we provide an improved reciprocally convex combination inequality (RCCI), which includes some existing ones as its particular cases. We construct an eligible stochastic Lyapunov–Krasovskii functional to capture more information about TDs, triggering signals, and MJPs. Based on a well-designed event-triggered control scheme, we derive several novel stability criteria for the underlying systems by employing the new RCCI and other analytical techniques. Finally, we present two numerical examples to show the validity of our methods.

Authors: Dai Lihua , Wang Junjie , Ni Yonggen , Xu Bin 
Published: January 2021

AbstractIn this paper, we consider a new fractional-order predator–prey model with Holling type-III functional response and stage structure. Based on the Lyapunov stability theory and by constructing a suitable Lyapunov functional, we obtain some sufficient conditions for the existence and uniqueness of positive solutions and the asymptotic stability of the positive equilibrium to the system. Finally, we give some numerical examples to illustrate the feasibility of our results.
Survival and ergodicity of a stochastic Holling-III predator–prey model with Markovian switching in an impulsive polluted environment
Authors: Qin Wen , Zhang Hanjun , He Qingsong 
Published: January 2021

AbstractBased on the effects of white noise and colored noise, we propose a stochastic Holling-III predator–prey model in an impulsive polluted environment. Firstly, we prove an existence and uniqueness theorem of the presented model. Secondly, we establish sufficient criteria of extinction, nonpersistence in mean, and weak persistence in mean for both prey and predator species. Thirdly, with the aid of Lyapunov functions, we prove that this system is ergodic and has a unique stationary distribution under certain conditions. Finally, we verify the theoretical results by performing some numerical simulations.

Published: January 2021

AbstractBackgroundThis study aimed to evaluate the prognostic value of pretreatment18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in patients with localized primary gastrointestinal stromal tumors (GISTs) and to compare the predictive values of18F-FDG PET/CT parameters with those of clinicopathological prognostic factors.MethodsSixty-two localized GIST patients who underwent staging with18F-FDG PET/CT from January 2007 to December 2013 before surgery were retrospectively enrolled. A volume of interest with a standardized uptake value (SUV) threshold of 2.5 was used to determine the metabolic tumor volume (MTV) and total lesion glycolysis (TLG). These metabolic indices, along with the maximum SUV (SUVmax), were analyzed to evaluate recurrence-free survival (RFS). Other significant clinical and pathologic indices were also retrospectively reviewed for RFS analysis.ResultsPatients were followed up for a median of 42.0 months (range, 5.6–111.5). During the follow-up period, 13 patients (21.0%) experienced disease recurrence. In univariate analysis, tumor size (> 5 cm), mitotic count (> 5/high-power field), modified National Institutes of Health (NIH) consensus criteria, adjuvant imatinib treatment, SUVmax (≥ 7.04), MTV (≥ 50.76 cm3), and TLG (≥ 228.79 g) were significant prognostic factors affecting RFS (p< 0.05). In multivariate analysis, only MTV (hazard ratio, 17.69; 95% confidence interval [CI], 2.03–154.17,p= 0.009) and TLG (hazard ratio, 20.48; 95% CI, 2.19–191.16,p= 0.008) were independent prognostic factors for RFS. The 5-year RFS rates were 96.4% and 96.6% in patients with a low MTV and TLG and 27.3% and 23.6% in patients with a high MTV and TLG, respectively (p< 0.001).ConclusionMTV and TLG are independent prognostic factors for predicting recurrence in patients with localized primary GIST. Patients with a high MTV or TLG are at risk for poor prognosis and should be closely observed for disease recurrence.

Authors: Siahmoshtei Javad , Delavar Ali , Borjali Ahmad 
Published: January 2021

AbstractBackgroundThis study aims to design and validate ten projective images ofYoung’s Early Maladaptive Schema(EMS) domains. For this purpose, two questions are to be addressed. (1) How is the factorial structure of the projective images of EMS domains? (2) Do the images designed in the domains of disconnection and rejection, impaired autonomy and performance, impaired limits, other-directedness, and over-vigilance and inhibition have sufficient validity?MethodsThis is an applied mixed-methods exploratory study, in which the statistical population consisted of psychologists from Tehran Province in the qualitative section (n = 8) as well as other individuals aged between 18 and 65 years (mean age = 33) from Qazvin in the quantitative section (n = 102) in 2018. The research questions were analyzed through principal axis factoring with a varimax rotation, confirmatory factor analysis, Pearson correlation coefficient, and Cronbach’s alpha.ResultsAccording to the results, ten images and five domains of Young’s EMSs contribute to a simple structure. Accounting for 70.35% of the total variance of EMSs, the five dimensions include disconnection and rejection, impaired autonomy and performance, impaired limits, other-directedness, and over-vigilance and inhibition.ConclusionsThe results indicated that the designed projective images yielded acceptable construct validity.

Abstract
Background
Relationship between emotional intelligence and emotional variables such as stress, depression, anxiety and mental health has been well documented in child and adult samples. New insights into the association between emotional intelligence and different components of mental health in one study (cognitive, emotional and behavioral dimensions) can help patients, therapists, relatives, and friends to understand, explain, and cope with symptoms. There have been no studies assessing the association between the emotional intelligence (EI) with various factors in Lebanon. This study principal aim was to evaluate how EI is related to mental health issues: social anxiety, depression, alcohol use disorders (AUD), work fatigue, stress and alexithymia in Lebanon.

Methods
789 participants were enrolled in a cross-sectional study between November 2017 and March 2018. A cluster analysis was used to evaluate participants’ profiles with the help of emotional intelligence subscales, to separate the Lebanese population into equal limited units with different characteristics using the K-mean technique.

Results
Three clusters were computed dividing participants into low EI (cluster 1; 24.5%), moderate EI (cluster 2; 43.7%) and high EI (cluster 3; 31.7%) respectively. Fitting into the cluster 1 (low EI) was significantly associated with higher AUD, alexithymia, anxiety, depression, perceived stress, social phobia, emotional, mental and physical work fatigue, suicidal ideation compared to cluster 3 (high EI). Fitting into the cluster 2 (moderate EI) was significantly correlated with higher AUD, depression, alexithymia, anxiety, perceived stress, social phobia, mental work fatigue and suicidal ideation compared to cluster 3 (high EI).

Conclusion
This study results suggest that emotional intelligence is related to different variables, warranting interventions to limit/decrease alcohol abuse and mental/psychological illnesses as much possible.

Published: January 2021

Abstract
As a royal temple, the Fengguo Temple has profound historical, artistic, scientific and social values. With a thousand-year history, it is one of the three existing temples of the Liao Dynasty in China. Now there remains the Main Hall with delicate wall paintings and vivid painted sculptures. The research subject of this paper is the painted Bodhisattva sculptures in the Main Hall. The study target is to reveal the craftsmanship and materials of the painted Bodhisattva sculptures. X-ray detection and the ground-penetrating radar were employed to explore the internal structure of the painted sculptures reasonably. Through microscope analysis, X-ray fluorescence spectrometer, X-ray diffractometer, scanning electron microscopy and infrared spectroscopic analysis, the chemical constituents and hierarchical structure of the pigment layer were detected and analyzed. The grain composition and chemical composition of the base layer were presented as well. The research results offer detailed documents for subsequent restoration and pave the way for preventive conservation. Finally, this paper summarized the craftsmanship and materials of painted sculpture works in different periods, so as to explore the development history of the painted sculptures culture.
Post-Western sociologies: what and why?
Authors: Xie Lizhong 
Published: January 2021

Abstract“Post-Western sociologies” mainly refer to some sociological systems constructed by non-Western and Western sociologists, after the so-called “Western sociologies” have been spread to the non-Western world. It includes various types, such as “non-westernized Western sociologies,” “westernized non-Western sociologies,” and “non-Western sociologies.” “Post-Western sociologies” therefore are neither equal to “non-Western sociologies” nor equal to “de-westernized” or “anti-westernized” sociologies. Compared with concepts such as “de-Westernization” or even “indigenization,” the concept of “post-Westernization” is more inclusive.

Abstract
Background
Familial adenomatous polyposis (FAP) is characterized by the presence of hundreds to thousands of colonic polyps, and extracolonic manifestations are likely to occur. Pancreatic tumors are rare extracolonic manifestations in patients with FAP, among which solid-pseudopapillary neoplasm (SPN) are extremely rare. We report here a patient with an SPN of the pancreas found during the follow-up of FAP.

Case presentation
A 20-year-old woman was diagnosed with FAP 3 years previously by colonoscopy which revealed less than 100 colonic polyps within the entire colon. She complained of left upper abdominal pain and a 10-cm solid and cystic pancreatic tumor was found by computed tomography scan. Solid and cystic components within the tumor were seen on abdominal magnetic resonance imaging. Simultaneous laparoscopic resection of the distal pancreas and subtotal colectomy was performed. Histopathological findings confirmed the pancreatic tumor as an SPN without malignancy. Abnormal staining of beta-catenin was observed by immunohistochemical study. Multiple polyps in the colorectum were not malignant. Molecular biological analysis from peripheral blood samples revealed a decrease in the copy number of the promoter 1A and 1B region of the APC gene, which resulted in decreased expression of the APC gene.

Conclusions
A rare association of SPN with FAP is reported. The genetic background with relation to beta-catenin abnormalities is interesting to consider tumor development. So far, there are few reports of SPN in a patient with FAP. Both lesions were treated simultaneously by laparoscopic resection.

Abstract
Background
Infectious diseases remain a leading cause of mortality and morbidity around the world, and those caused by bacteria are common in the East African region. In this region, trade and consumption of herbal medicine has been expanding in the recent decades. Herbal medicines may be contaminated with pathogenic bacteria; however, there is limited information due to fragmented studies in East Africa. In this meta-analysis, we critically analyzed original research related to the incidence of pathogenic bacterial contaminants of HM in the East African region since 2000. The aim was to create a comprehensive understanding of the extent and dynamics of bacterial contamination in HM, to guide future research and concerted public health protection in the region.

Methodology
The study was conducted according to the standards of the Preferred Reporting Items for Systematic Reviews and Meta-analyses. We searched and evaluated published articles from eleven electronic databases (Google Scholar, PubMed, HerbMed, MEDLINE, Science Direct, Scifinder Scholar, Cochrane Library, International Pharmaceutical Abstracts, EMBASE, Biological Abstracts and Commonwealth Agricultural Bureau Abstracts). Prevalences of different bacterial species, Cochran’s Q test, and the I2 statistic for heterogeneity were evaluated using a software called MedCalcs. Random and fixed effects models were used to determine the pooled prevalence of clinically significant bacteria from studies which were included in this meta-analysis. The potential sources of heterogeneity were examined through sensitivity analysis, sub-group analysis, and meta-regression at 95% level of significance.

Results
Fourteen studies met our inclusion criteria. Overall, the studies were highly heterogeneous (I2 = 98.48%) and there was no evidence of publication bias. Escherichia coli was the most prevalent contaminant. Salmonella spp. and Shigella spp. were the most frequently reported primary pathogens with pooled prevalence of 10.4% and 6.3%, respectively. Our findings are in tandem with recent systematic reviews conducted in Europe and Asia, but are in discrepancy with the reviews recently conducted in southern Africa.

Conclusion and recommendations
The East African herbal medicine industry poses considerable health risks to communities through dissemination of clinically significant bacteria. Presence of enteric bacterial contaminants indicates possible fecal pollution of herbal medicine region-wide. Adequate research pertaining to microbial safety of herbal medicine in the East African countries remains highly desired. The latter will enable establishment of strong, region-wide herbal safety mechanisms in order to support comprehensive public health protection in East Africa.

Published: January 2021

Abstract
Background
Globally, diabetes is a leading cause of impairment of quality of life. In the sub-Saharan African region, there is a need for studies that provide more valid assessment of effect of diabetes on quality of life (QoL). This study aimed at assessing quality of life among patients with diabetes attending a tertiary health service in Nigeria.

Methods
The study design was a case-control. Diabetic cases were randomly recruited from the University of Calabar Teaching Hospital, while non-diabetic controls were civil servants and retirees. The validated and pretested WHOQoL-BREF instrument was used to assess quality of life, with higher scores indicating higher quality of life.

Results
Three hundred and thirty subjects were studied, with mean ages of males and females of 55.2 ± 4.8 and 51.8 ± 6.3 years, respectively. The mean total QoL score was 75.77 ± 11.2, with no significant difference between males and females. Among male and female cases, the mean score of the physical health domain was significantly lower for cases compared with controls (p = 0.05). Male cases compared with controls had higher scores for the environment domain (p < 0.05). Older age and higher systemic blood pressure were associated with lower QoL scores for both sexes (p < 0.05). Unmarried status, obesity, and poor glycemic control (HbA1c > 7%) were associated with lower QoL scores (p < 0.05). Fasting blood sugar (FBS) level and lipid profile were not significantly correlated with QoL score in both sexes (p > 0.05).

Conclusion
Diabetes contributes to low quality of life among males and females, with significant differences in the affected domains. Diabetes care providers should identify affected domains during clinic consultation, in order to improve provision of more effective care.
