Published: August 2023

Abstract
Background: Suicidal ideation is a pressing public health concern, particularly among adolescents. The objective of this study was to examine the prevalence of and factors associated with suicidal ideation in urban Chinese adolescents, addressing an important gap in current research.
Methods:This study employed an online survey to examine the demographic characteristics and mental health status of secondary school students in Lianyungang City. The assessment included the use of the Patient Health Questionnaire-9 (PHQ-9) to evaluate suicidal ideation in adolescents. Additionally, anxiety symptoms were assessed using the seven-item Generalized Anxiety Disorder (GAD-7) questionnaire, while social support was measured using the Perceived Social Support Scale (PSSS).
Results:Among 3443 adolescents, the prevalence of suicidal ideation was 22.1%, with a significantly higher proportion of suicidal ideation among female adolescents than males (P < 0.001). Binary regression analysis revealed that female sex (OR = 1.828, 95% CI: 1.500–2.229, P < 0.001), anxiety symptoms (OR = 9.417, 95% CI: 7.006–12.659, P < 0.001), troubled parental relationships (OR = 1.988, 95% CI: 1.587–2.492, P < 0.001), and spending more than 5 hours on electronic devices weekly (OR = 1.582, 95% CI: 1.238–2.022, P < 0.001) were identified as risk factors for suicidal ideation. Conversely, family support was found to be a protective factor against suicidal ideation (OR = 0.890, 95% CI: 0.862–0.920, P < 0.001). Furthermore, older age, higher annual household income, and spending less than 5 hours per week using electronic devices were linked to a lower severity of suicide ideation; whereas female sex and anxiety symptoms were associated with a higher severity of suicidal ideation (all P < 0.05).
Conclusions: This study highlights high adolescent suicidal ideation rates and recommends gender-specific interventions, anxiety management, family support, and addressing excessive electronic device use for improvement in well-being.

Abstract
To explore the maternal image of left-behind children (LBC) and the impact of mothers’ absence on their mental health, we randomly selected 2,623 participants (546 LBC and 2,077 non-LBC) whom we tested using the Mental Health Inventory of Middle-School Students (MMHI-60) and the Maternal Image Scale. The scores of LBC on the Positive Maternal Image Scale were significantly lower than those of non-LBC; the scores of LBC on the Negative Maternal Image Scale were significantly higher than those of non-LBC, and the mental health level of LBC was significantly lower than that of non-LBC. In addition, positive maternal image (PMI) and negative maternal image (NMI) fully mediate the time mothers spend at home and their children’s mental health. The findings indicate that as mothers spent less time at home, the maternal image of LBC became damaged; the children’s mental health also declined.

Published: August 2023

Abstract
Background Measure central corneal thickness (CCT) and central corneal epithelial thickness (CCET) with anterior segment-optical coherence tomography (AS-OCT) in individuals with impaired glucose metabolism and to analyze, the effect of impaired glucose metabolism on the cornea.Methods 140 eyes of 70 participants, including 20 healthy controls, 17 insulin resistant, and 33 prediabetic, were evaluated by AS-OCT. Glucose metabolism was examined using a 2-hour 75 g oral glucose tolerance test and glycated haemoglobin A1c (HbA1c). Anthropoemetric measurements, physical examinations, and blood pressure were recorded of all participants. The biochemical parameters were studied.Results The mean age of the participants was 37.93 ± 12.30 years, and the mean HbA1c was 5.50 ± 0.38%. CCET measurements were significantly different and higher in the prediabetic group (p < 0.01). A significant positive correlation was found between both CCETR and CCETL and age, HbA1c, and fasting plasma glucose (p < 0.05). There was found a significant positive correlation was found between CCETR and total cholesterol, triglyceride, and low-density lipoprotein (p < 0.05). Anthropoemetric parameters were significantly different in prediabetics (p˂0.001 and p˂0.05). There was a significant negative correlation between body fat percentage and CCT (p˂0.05). CCET showed a significant positive correlation with neck circumference (p < 0.05).Conclusions It may be suggested that impaired metabolic processes during prediabetes may affect CCET. We believe that prediabetes detection should not be limited to HbA1c and OGTT; A multifactorial algorithm could be developed. AS-OCT may be an easily accessible and useful tool for the early diagnosis of prediabetes.

Abstract

The golden twin-spot moth, Chrysodeixis chalcites Esper (Lepidoptera: Noctuidae), is a polyphagous, polyvoltine crop pest occurring natively from northern Europe to Mediterranean Africa and the Canary Islands. Larvae feed on a wide variety of naturally occurring plants as well as soybean and other legume crops, short staple cotton, tomato, potato, peppers, tobacco, and banana. Chrysodeixis chalcites has been recorded in agricultural lands in the Ontario peninsula in eastern Canada and in northern counties of Indiana, USA. Given the strong potential for C. chalcites to invade USA crop lands, it is important to identify habitats most likely to sustain growing populations of this pest. Using occurrence data from its homerange, and environmental predictors including bioclimatic conditions, elevation, and human disturbance, we trained three ecological niche models, and used these models to estimate an ensemble prediction of habitat suitability in the contiguous US. Because human impact is potentially a confounding predictor, models were trained both with and without it. High habitat suitability was projected for the Atlantic coast from New England to Florida, the Gulf coast, the lower Midwest, and the Pacific coast and Central Valley of California. Though model predictions were robust, we recommend caution in their interpretation. First, agricultural lands are bioclimatically altered landscapes, and these alterations not reflected in bioclimatic data gathered from weather stations. Second, though the inclusion of human impact did not alter predictions on a large scale, it produced predictions favoring major metropolitan areas as suitable habitat, which we interpret as an artifact.

Published: August 2023

Abstract
Venturing into the crossroads of Artificial Intelligence (AI) and economic development, this study employs AI models for economic forecasting within the context of Iraq, a quintessential rentier state. Drawing on the theoretical underpinnings of rentier state theory and diversification strategies, it harnesses OpenAI's advanced language models, ChatGPT and googles AI Bard, to generate an array of potential economic trajectories. The results provide an insightful probe into the impacts of global oil market trends, the socio-economic implications of public dissatisfaction under economic instability, and the potential benefits of economic diversification. The study investigates the unique challenges facing Iraq, a country rich in oil resources but wrestling with economic stagnation and socio-political instability. The AI models are utilized to generate and dissect potential future scenarios for Iraq's economy, elucidating the critical issues related to its heavy dependence on oil, the sustainability of its bloated public sector, and the ramifications of these factors on socio-economic stability. The analysis underlines the urgent need for robust economic diversification and provides strategic policy recommendations to steer Iraq towards a more resilient and sustainable economic future. This study illuminates the pathway towards economic diversification in Iraq by seamlessly integrating AI models with traditional research methodologies. It demonstrates the potential of AI as an essential tool in economic forecasting and policy planning within economic development studies.

Published: August 2023

Abstract
In this study, trend analysis of total suspended solids (TSS) and total phosphorus (TP) concentrations and loads are performed, combining bootstrapping with the Weighted Regressions on Time, Discharge, and Season i.e., WRTDS_BT technique. The technique is used at ten selected monitoring stations of Northern Lake Erie, Eastern Lake Huron, and Lake Ontario & Niagara Peninsula in Ontario, Canada. Trend analysis over major tributaries reveals that trends in TSS concentrations and loads were highly variable, while there was a significant decline in TP concentrations and loads. However, in most tributaries, TSS and TP concentration levels are significantly higher than the provincial and national guidelines and objectives. To be precise, TSS concentration levels are significantly higher than Canadian Water Quality Guidelines (CWQG) for the TSS concentration in tributaries of 30 mg/L (following Toronto Region Conservation Authority (TRCA), Ontario) and TP concentration levels are significantly higher than the Ontario’s provincial water quality objectives (PWQO) guidance for the TP concentration in tributaries of 0.03 mg/L. Moreover, our findings suggest that changes in land management practices in agricultural areas, such as tillage, tile drainage and fertilizer/manure application may play an important role for the analysed trend.
WITHDRAWN: Introducing new heterogeneity indices based on integrated petrophysical heterogeneity analysis in Sarvak carbonate reservoir of an Iranian oilfield in Dezful Embayment

Published: August 2023

Abstract
Heterogeneity is a very significant factor in reservoir static modeling, reservoir simulation, and determining hydrocarbon recovery of petroleum reservoirs. In this study, we tried to quantify and calculate different heterogeneity indicators for one cored well in the Sarvak reservoir of an Iranian oilfield located in the Dezful embayment (Zagros Basin). The coefficient of variation (CV) of permeability, Dykstra-Parsons Coefficient, and Lorenz Coefficient were used for heterogeneity analysis in the cored intervals of the formation. In addition, the coefficient of variation (CV) based on the petrophysical porosity log was calculated for whole intervals which can be used for heterogeneity index, especially in un-cored intervals. In this study, we checked the relationship between the conventional heterogeneity indices with some parameters including residual oil (Sor), variography, reservoir quality index (RQI), synthetic velocity deviation log (VDL), and skewness for the first time. This study showed that the CV of porosity can be used as reliable heterogeneity index in un-cored intervals. In addition, skewness of porosity and permeability can be used as heterogeneity indicators instead of routine static heterogeneity approaches. The existence of the shale and dolomite influences the reservoir heterogeneity. Moreover, by increasing the range of variography, CV of porosity rises. The VDL (as diagenesis indicator) and Sor have an inverse relationship with the CV of porosity. Therefore, in un-cured intervals various parameters can be used as reservoir heterogeneity indices.
Friction as Energy Dissipation Process Associated with Superlubricity of Solids
Authors: Zhang Bo 
Published: August 2023

Abstract

The paper shows that work in a quantum system is also quantized, the quantum work is equivalent to the Debye energy and the superlubricity of solids is derived from the quantum work. The prerequisite for the superlubricity is that the lateral force at contact surfaces in sliding is less than the Debye force so that the phonon of the solids is not excited.

Abstract
Rubber wood fly ash (RWFA) is one of the main components of biomass ash materials. This research investigates the possibility of using RWFA geopolymer (RWFAG) to stabilize marginal lateritic soil (MLS) as green subbase materials. RWFA was used as a starting material. The studied influence factors included MLS:RWFA ratio, sodium silicate (NS):sodium hydroxide (NH) ratio, soaked and unsoaked conditions, and curing time. The study involved testing the unconfined compressive strength (UCS), indirect tensile strength (ITS), and conducting microstructure. The test results revealed that the optimal liquid content for the MLS-RWFAG specimens ranged between 12–24% for all ingredients. As the RWFA content increased, the maximum dry unit weight of the MLS-RWFAG decreased due to the lower specific gravity of RWFA. The MLS-RWFAG specimen with 30% RWFA content and an NS:NH ratio of 70:30 yielded the maximum UCS and ITS. The SEM-EDS analysis demonstrated the production of C-S-H and N-A-S-H gels, resulting in a dense and homogeneous matrix in the MLS-RWFAG specimens. Considering cost-effectiveness, the optimum ingredients for the MLS-RWFAG specimen were identified at an MLS:RWFA ratio of 70:30 and an NS:NH ratio of 10:90, meeting the 7-day soaked UCS requirement for pavement subbase materials. Moreover, the CO2-eq emissions from MLS-RWFAG specimens were lower compared to those from 3% cement-stabilized MLS samples. These findings strongly support the use of RWFAG as a viable alternative to Portland cement for stabilizing MLS in subbase materials.

Published: August 2023

Abstract
Artificial intelligence (AI), represented by OpenAI's Chat Generative Pre-trained Transformer (ChatGPT), has shown increasing promise in various fields, including medicine. Although prior studies have investigated ChatGPT’s role in medicine, they have done so only in English, leaving its proficiency in non-English languages relatively unexplored. Therefore, this study aimed to evaluate and compare the performance of ChatGPT in responding to dermatology specialty certificate examination (SCE) questions in both English and Korean. A total of 200 dermatology SCE questions were presented to a ChatGPT model in both English and Korean languages. The model's responses were evaluated for correctness, and further analyses were conducted based on cognitive function, evaluation category, and dermatological topics. ChatGPT achieved an overall accuracy of 69.0% and 57.0% for English and Korean questions, respectively. These differences were considered to be statistically significant (p=0.013). However, the sub-analyses results based on cognitive function, evaluation category, and dermatological topics between both languages were not consistent. Thus, although ChatGPT demonstrated considerable accuracy in answering dermatology SCE questions, its performance varied substantially based on the language used. This finding underscores the potential of AI applications in the multilingual medical context of dermatology while also emphasizing the need for further advancements to address language-related limitations.

Published: August 2023

Abstract
Juvenile psammomatoid ossifying fibroma (JPOF) is an osteofibrous neoplasm that originates in the craniofacial skeleton typically during the first three decades of life. JPOFs usually involve the orbit, paranasal sinuses or the jaws. Extensive involvement of the anterior cranial base with compromised visual function is a rare phenomenon. In such clinical context, a definite diagnosis can only be made on the basis of histopathological findings, given the absence of pathognomonic radiological features. Despite being considered a benign entity, JPOFs present a locally aggressive behavior. Therefore, these neoplasms must be included in the differential diagnosis in every patient harboring a skull base osteofibrous lesion and, once diagnosed, gross total surgical removal should be attempted. In this study we present our experience in the diagnosis and treatment of a patient diagnosed with a giant JPOF involving the cranial base.

Abstract
Background
Diabetes is an independent risk factor for thyroid nodules (TNs), however, the influencing factors of TNs have not been fully clarified under the condition of diabetes. We aimed to explore the correlates of TNs in type 2 diabetes (T2D) patients.
Methods
In this cross-sectional study, 1444 Chinese adults with T2D were included. Clinical and biochemical characteristics were collected. The overall prevalence of TNs was 45.6%. Spearman correlation analysis and logistic regression analysis were used successively to analyze the independent correlates of TNs.
Results
The results from univariate and further logistic regression analyses showed that female (OR: 1.656; 95% CI: 1.255–2.185), age (OR:1.017; 95% CI:1.005–1.030), UA (OR: 0.998; 95% CI: 0.997-1.000), free triiodothyronine (FT3) (OR: 1.400; 95% CI: 1.169–1.675) and peripheral atherosclerosis (PAS) (OR: 1.614; 95% CI: 1.155–2.255) independently correlated with TNs in all patients. Subsequently, stratified by sex and age, the results displayed that FT3 (OR: 1.585 ; 95% CI:1.211–2.073), PAS (OR: 1.759; 95% CI: 1.148–2.695) and duration of diabetes (OR: 1.037; 95% CI: 1.008–1.067) in female while age (OR: 1.020 ; 95% CI: 1.007–1.034) and PAS (OR: 1.802 ; 95% CI: 1.223–2.656) in male, and age (OR: 1.045 ; 95% CI: 1.025–1.065) and female (OR: 1.892; 95% CI: 1.361–2.629) in patients below 60 years old while female (OR: 1.643 ; 95% CI: 1.181–2.284), PAS (OR: 2.077; 95% CI: 1.269–3.401), FT3 (OR: 1.316 ; 95% CI: 1.044–1.661) and magnesium (OR: 7.399; 95% CI: 1.060-51.628 ) over 60 years old, significantly related to TNs. The prevalence of TNs was high in T2D patients.
Conclusions
The independent correlates of TNs were multifactorial, and there existed differences in different physiological states.

Published: August 2023

Abstract
Background
To investigate the accuracy and safety of a newly constructed robotic arm which can cover the whole process of THA, we performed a series of robot-assisted total hip replacement on the cadaver.
Methods
Fifteen frozen cadaveric specimens (30 hips) were used for this study. In this investigation, United hip system and Longwell robotic-assisted system were used. The entire lower limb was CT scanned prior to surgery. The 3D model was produced based on CT data, the site of the prosthesis, including acetabular anteversion, inclination angle, and the position of femoral prosthesis were planned. With the assistance of a robotic arm, the surgeon changed the parameters based on the preoperative plan and the actual condition during surgery, and completed the whole procedure. Following surgery, we measured the acetabular anteversion angle, acetabular inclination angle, femur anteversion angle, combined anteversion angle, stem angulation, and canal-fill-ratio.
Results
The parameters proved that the acetabular anteversion angle was 16.85 ± 3.00 °, and the acetabular inclination angle was 40.38 ± 5.37 °, femur anteversion angle was 15.90 ± 9.01 °, combined anteversion angle was 32.75 ± 9.03 °, stem angulation was 1.84 ± 0.99 °, leg length discrepancy was 2.47 ± 1.43mm. The canal-fill-rate (CFR) of femoral prosthesis was also satisfactory.
Conclusion
The accuracy and safety of this novel robotic arm are suitable for preparing both the acetabular and femoral sides, providing evidence for clinical trial.
