Application of Machine Learning Approaches in Particle Tracking Model to Estimate Sediment Transport in Natural Streams
Authors: Baharvand Saman , Ahmari Habib 
Published: June 2023

Abstract
Several empirical equations and machine learning approaches have been developed to predict dispersion coefficients in open channels; however, the ability of some learning-based models to predict these coefficients has not yet been evaluated, and the direct application of machine learning-based dispersion coefficients to Lagrangian sediment transport models has not been studied. In this research, data from previous studies is used to evaluate the ability of ensemble machine learning models, i.e., random forest regression (RFR) and gradient boosting regression (GBR), to predict longitudinal and transverse dispersion in natural streams. The optimal principal parameters of ensemble models were adjusted using the grid-search cross-validation technique, and the machine learning-based dispersion models were integrated with a Lagrangian particle tracking model to simulate suspended sediment concentration in natural streams. The resulting suspended sediment concentration distribution was compared with the field data. The results showed that GBR model, with a coefficient of determination (R2) of 0.95, performed better than the RFR model, with R2 =0.9, in predicting the longitudinal dispersion coefficients in a natural stream in both training and testing stages. However, the RFR model with R2 = 0.94 performed better than the GBR (R2 = 0.91) in predicting the transverse dispersion in testing stage. Both models underestimated the dispersion coefficients in the training and testing stages. Comparison between the PTM with ensemble dispersion coefficients and empirical-based dispersion relationships revealed the better performance of the GBR model compared to the other two methods.

Published: June 2023

Abstract
In this paper, we use two types of designs to construct repairable threshold schemes, and calculate information rate and communication complexity of the schemes to analyze their performance. Firstly, SB(2λ + 1, λ, 4λ + 3) is used to construct the (3, 4λ + 3, 2λ + 1)−RTS, which is based on (3λ + 3, 4λ + 4)−Shamir threshold scheme. Secondly, the mutually orthogonal Latin squares are constructed, and a RTD(q, 1; q 2) is obtained by them. Further, the RB(q, 1; q 3) is obtained through filling hole method. (2, n, q)−RTS based on (q, 2q − 1, q 3)−Ramp threshold scheme and (3, n, q)−RTS based on (2q, 3q − 3, q 3)−Ramp threshold scheme are constructed by RB(q, 1; q 3), where 2q 2 ≤ n ≤ q 2 (q 2 + q + 1). Finally , the information rate and the communication complexity of three repairable threshold schemes are calculated, and the performance of these schemes is analyzed. Compared with the existing schemes, the results show that (2, n, q)−RTS and (3, n, q)−RTS constructed by RB(q, 1; q 3) have higher information rate and lower communication complexity.

Authors: Li Guo , Zhang Lijun , Liu Meiyan 
Published: June 2023

Abstract

Objective
This meta-analysis aimed to explore the association between inflammatory factors, HRV, and the coexistence of coronary heart disease (CHD) and depression.
Methods
The most common databases were chosen for data research, including PubMed, Web of Science, and EMBASE. We searched the data from the inception date through Mar. 16, 2023. The effect estimates and heterogeneity was synthesized by Review Manager version 5.3. Sensitivity analysis and publication bias were analyzed by STATA software.
Results
By searching the databases, we identified a total of 6750 articles. There were 22 articles left after selection, including 6344 participants. This meta-analysis indicates that CHD patients with depression have higher levels of CRP (0.45 [0.08, 0.82], P=0.02), hs-CRP (0.28 [0.07, 0.48], P=0.008) and a lower level of SDNN (-0.64 [-1.11, -0.17], P=0.008), SDANN (-12.77 [-21.20, -4.33], P=0.003), SDNNIDX (-13.83 [-15.94, -11.72], P<0.00001), RMSSD (-8.02 [-13.62, -2.43], P=0.005) pNN50 (-0.86 [-1.41, -0.31], P=0.002), than those without depression.
Conclusion
This study highlights that a higher level of inflammatory factors and lower HRV would help to predict depressive symptoms in CHD patients.
Improvement of FLIP CHIP detection and localization based on traditional image algorithm

Abstract
Surface mount technology (SMT) in integrated circuits, is one of the pillars of electronic information industry. Its degree of development is also one of the core indicators to measure the level of science and technology of a country, which affects process of social information. In recent years, chip technology has improved, and surface mount technology has also achieved remarkable results. But there are still two problems, one is for high-density integrated chips (such as BGA, FLIP CHIP, etc.), the recognition of pass rate is low by the light, chip quality, and other external factors such as more significant impact. The other is traditional template matching algorithm used for positioning, which takes a long time and leads to low production placement speed. In this paper, we take FLIP CHIP as an example and propose a regional screening algorithm to reduce interference, which includes area screening and roundness screening to extract the most valuable part of image information. The regional connected domain method is proposed to obtain the center of gravity set of weld balls and the circle fitting function in OpenCV is used to calculate weld ball radius. The pre-processed image is taken to improve linear fitting method to calculate the chip body size, the average pitch of solder ball, the rotation angle, and the coordinates of the center point of the chip. The remapping search algorithm is used to calculate the number of empty spaces. Then, the rotation angle under the obtained image coordinate system and the center point coordinates of chip are converted to the physical coordinate system at the time of positioning. Then, the offset is output by subtracting from the size of acquired ROI. It is more advantageous than the method of template matching to improve detection speed while ensuring accuracy.

Abstract
Our objective was to identify knowledge gaps in healthy hair care practices in African American clientele and the hair stylists and barbers who serve them. This was a cross sectional population-based survey study, distributed from August 2021 to November 2021 in salons and barbershops within Philadelphia and the surrounding regions. Participants were a random sample of 202 self-identifying African American clientele and 115 hair stylists/barbers, ≥ 18 years old. Survey response rate was 71%. Results revealed that 66.8% of clientele prioritize healthy hair over the style of their hair, 43.1% of clientele would consult their hair stylist/barber first when experiencing hair loss, while 21.3% would consult a dermatologist first. When concerned about client hair loss, 59.1% of hair stylists’ and barbers’ first step was to give advice based on their own expertise. Hairstylists and barbers had a higher mean score than clientele (2.9/5 vs 2.4/5) regarding knowledge of hair styles that increase risk of hair loss. In summary, the key points are: 1) In the African American community, healthy hair is a priority and clientele are more likely to refer to their hairstylists and barbers regarding management of hair loss. 2) There may be a gap in knowledge pertaining to hairstyles that increase risk for alopecia amongst hairstylists, barbers, and their clientele. 3) Dermatologists should partner with hair stylists and barbers to develop outreach programs targeting knowledge gaps within the community to improve prevention and early detection of hair loss.

Authors: Rubel Julian , Quest Jannis , Pruessner Luise , Timm Christina , Hartmann Steffen , Barnow Sven , Rittmeyer Lisa , Rosenbaum David , Lalk Christopher 
Published: June 2023

Background
Generalized anxiety disorder (GAD) is a highly prevalent and severely distressing condition that can lead to functional impairments and is considered one of the most difficult anxiety disorders to treat. Following new technological developments, a highly structured cognitive behavioral therapy (CBT) approach that has already shown success in face-to-face psychotherapy can be implemented: internet-delivered CBT (iCBT). There is now evidence for the efficacy of both guided and unguided iCBT interventions for GAD regarding symptom reduction.

Objective
To establish the usefulness of such interventions, we plan to evaluate the efficacy of a web-based self-help program (Selfapy) for GAD in a relatively large sample. We aim to assess effects beyond symptom reduction, including effects on well-being, functioning, and mental health literacy, as well as the effect on health care burden, while testing the intervention in conditions comparable to routine care.

Methods
Patients (n=156) who have been diagnosed with GAD, are aged between 18 and 65 years, have internet access, and have sufficient German language skills will be recruited for this study. The intervention group (n=78) will receive access to the 12-week self-help web-based program Selfapy. The waitlist control group (n=78) will receive no intervention in the context of the study. However, both groups will be allowed to access further health care services (eg, psychotherapy, medication), reflecting current routine care in Germany. Outcome measures will be assessed at baseline (T1) and 6 weeks (T2) and 12 weeks (T3) after the start of the intervention. The primary outcome will be generalized anxiety symptoms and quality of life at T3. Additional outcomes include depression, work capacity, therapy-related expenses and burdens, health literacy, and negative effects.

Results
By May 2023, all participants had finished the trial and the report was being prepared for publication.

Conclusions
Web-based interventions may be an important addition to the German health care system to reduce barriers to treatment access. Further, they may prove cost-effective for the treatment of GAD.

Association Between Daily Internet Use and Incidence of Chronic Diseases Among Older Adults: Prospective Cohort Study
Authors: Li Peiyi , Zhang Chenyang , Gao Shuanliang , Zhang Yanbo , Liang Xiaolong , Wang Chengdi , Zhu Tao , Li Weimin 
Published: June 2023

Background
Chronic disease incidence among the elderly is increasing, which is correlated with the acceleration of population aging. Evolving internet technologies may help prevent and provide interventions for chronic diseases in an accelerating aging process. However, the impact of daily internet use on the incidence of chronic diseases is not well understood.

Objective
This study aims to investigate whether daily internet use by middle-aged and older adults may inhibit or promote the occurrence of chronic diseases.

Methods
We included participants from the China Health and Retirement Longitudinal Study (CHARLS), a longitudinal survey of Chinese residents aged ≥45 years. We assessed 8-year data from wave 1 (June 2011-March 2012) to wave 4 (July-September 2018) in CHARLS. Data from wave 4 were used for a cross-sectional study, and data from all 4 waves were used for a longitudinal study. Self-reported data were used to track variables, including internet use, use frequency, and the incidence of different chronic diseases. Cox proportional hazards modeling was applied in the longitudinal study to examine the relationship between daily internet use and chronic diseases among middle-aged and older adults, while adjusting for sociodemographic characteristics and health behaviors. In addition, longitudinal data were used to analyze internet usage trends, and cross-sectional data were used to analyze the factors influencing internet use.

Results
Among the 20,113 participants included in the longitudinal analyses, internet use increased significantly, from 2% to 12.3%, between 2011 and 2018. The adjusted model found statistically significant relationships between daily internet use and a lower incidence of the following chronic diseases: hypertension (hazard ratio [HR] 0.78, 95% CI 0.65-0.95, P=.01), chronic lung disease (HR 0.74, 95% CI 0.57-0.97, P=.03), stroke (HR 0.69, 95% CI 0.50-0.94, P=.02), digestive disease (HR 0.73, 95% CI 0.58-0.91, P=.005), memory-related disorders (HR 0.58, 95% CI 0.37-0.91, P=.02), arthritis or rheumatism (HR 0.60, 95% CI 0.48-0.76, P<.001), asthma (HR 0.52, 95% CI 0.33-0.84, P=.007), depression (HR 0.80, 95% CI 0.71-0.89, P<.001), and vision impairment (HR 0.83, 95% CI 0.74-0.93, P=.004). Moreover, our study also showed that with increasing frequency of internet use, the risk of some chronic diseases decreases.

Conclusions
This study found that middle-aged and older adults who use the internet have a reduced risk of developing chronic diseases versus those who do not use the internet. The increasing prevalence of daily internet use among middle-aged and older adults may stimulate contemplation of the potential role of internet platforms in future research on chronic disease prevention.
Single vs. Divided-Dose Prednisolone for the First Episode of Nephrotic Syndrome in Children
Authors: Khan Tania , Akhtar Shakil , Mukherjee Devdeep , Basu Surupa , Tse Yincent , Sinha Rajiv 
Published: June 2023

Background
Early morning single-dose prednisolone has a hypothetical advantage of less hypothalamic-pituitary-adrenal (HPA) axis suppression, but lack of robust evidence has resulted in variation in practice, with divided-dose prednisolone still commonly used. We conducted this open-label randomized control trial to compare HPA axis suppression between single-dose or divided-dose prednisolone among children with first episode of nephrotic syndrome.

Methods
Sixty children with first episode of nephrotic syndrome were randomized (1:1) to receive prednisolone (2 mg/kg per day), either as single or two divided doses for 6 weeks, followed by single alternative daily dose of 1.5 mg/kg for 6 weeks. The Short Synacthen Test was conducted at 6 weeks, with HPA suppression defined as postadrenocorticotropic hormone cortisol <18 µmg/dl.

Results
Four children (single=1 and divided dose=3) did not attend the Short Synacthen Test and were hence excluded from analysis. Remission was induced in all, and no relapse postremission was noted during the 6+6 weeks of steroid therapy. After 6 weeks of daily steroids, HPA suppression was greater in divided (100%) versus single dose (83%) (P = 0.02). Time to remission and final relapse rates were similar, but for those children who relapsed within 6 months of follow-up period, time to first relapse was shorter for divided dose (median 28 versus 131 days) P = 0.002.

Conclusions
Among children with first episode of nephrotic syndrome, single-dose and/or divided-dose prednisolone were equally effective in inducing remission with similar relapse rates, but single dose had less HPA suppression and longer time to first relapse.

Published: June 2023

Nanopowder pigments of CeO2 and CeO2:Fe were synthesized by precipitation method at a moderate calcination temperature of 500oC. The pigments exhibited pale yellow for CeO2 nanopowder and brick red for CeO2:Fe nanopowder. Both pigments possessed mesoporous and cubic fluorite structures of CeO2. The incorporation of Fe into CeO2 reduced crystallite size and increased surface area. Moreover, it widens bandgap energy and significantly improved the absorption property of CeO2 nanopowder.

Published: June 2023

Water loss has become a problem with the balance of a water system, including one in the industry. General opinion has considered evaporation as one of the main justifications for explaining the water loss, especially in the area with a higher daily temperature. A study was conducted on a wastewater treatment system owned by a manufacturing industry consisting of semi-open-air sedimentation and aeration ponds, which suddenly experienced a significant deficit in its water balance. Problem-solving was performed by 8-Step Problem Solving approach and root causes were confirmed by estimating water evaporation. The actual water evaporation rate (E) was approached by pan evaporation (Epan) using the partial pressure of the water vapour and the pan evaporation coefficient (Kpan). The study revealed that evaporation (1.67±0.59mm.d-1 and 1.72±0.62mm.d-1, for sedimentation pond and aeration pond, respectively) was not the main cause of sudden significant water loss (R2 = .490, p-value .05) and confirmed another root cause. In parallel, a water balance model was constructed and fitted the actual condition (R = .987). A countermeasure was performed against the confirmed root cause followed by a monthly evaluation of water loss using the constructed model with a 3σ threshold value (UCL = 9.55%) which showed the elimination of the problem.

Typology of terrain vague and emergence mechanisms in post-communist, post-industrial small and medium-sized towns in Slovakia: Case study of Humenné, Strážske and Vranov and Topľou
Authors: Hajduková Romana , Sopirová Alžbeta 
Published: June 2023

Abstract
There have been many problems associated with underutilized areas in towns, although they also offer significant potential for urban renewal, especially in post-communist, post-socialist countries, where a series of key historical events has caused socio-economic and political changes leading to urban decay. The underlying feature of unused areas is their apparent abandonment, absence of use, lack of identity but high potential. However, not all unused areas should be labelled as brownfields; therefore, we studied the terms commonly used to describe underutilized areas. We chose the term terrain vague to map and describe all apparently empty but still intriguing spaces in our model towns of Humenné, Strážske and Vranov and Topľou, in eastern Slovakia. Our paper aims to create a typology of terrain vague to better understand its manifestation in our conditions. It also aims to determine the causes that led to its emergence or as we call it the emergence mechanisms, in the context of post-industrial small and middle-sized towns in Slovakia. We combined field survey and desktop analysis methods to map terrain vague based on set criteria. We evaluated mapped terrain vague and, using the data, created a typology of terrain vague consisting of nine types and identified three key emergence mechanisms and their subcategories. We based them on commonly used terms that fit within the specific context of our model towns. By using the new typology and emergence mechanism, we can identify patterns running along towns with similar backgrounds that result in similar problems and develop solutions accordingly. Results of our research could be generalized and serve as a basis for future research aimed at finding strategies for revitalizing terrain vague in shrinking post-industrial towns facing different problems than prosperous cities.
Balance of Payments as a Monetary Phenomenon: An ARDL Bounds Test Method for Algeria
Authors: Ghilous Azeddine , Ziat Adel 
Published: June 2023

Abstract

Research background
Every country attempts to improve its balance of payments (BOP) position to enhance macroeconomic policy. Algeria, like many developing countries, is experiencing a BOP deficit. This raises concerns about the reasons for this deficit and prioritizes the quest for potential answers.

Purpose
In the context of the Monetary Approach to the balance of payments (MABP), this paper investigates the long-run relationship between domestic credit, inflation, interest rate, GDP, and net foreign assets to find whether BOP is a monetary phenomenon in Algeria from 1980 to 2019.

Research methodology:
The Autoregressive Distributed Lag (ARDL) bounds test, combined with the critical approximation p-values of Kripfganz and Schneider (2020), has been applied.

Results
The findings clearly showed a long-run relationship among the variables. The long-run estimates strongly supported MABP propositions, and domestic credit had a negative and statistically significant influence on net foreign assets. This suggests that Algeria’s BOP is a monetary phenomenon, and excess money supply played a crucial role in Algeria’s balance of payments disequilibrium.

Novelty
The contribution of this paper is the use of the ARDL bounds test in combination with the novel critical approximation p-values of Kripfganz and Schneider (2020), which provided more robust results. This study could help monetary authorities to elaborate the suitable policies in dealing with BOP problems in Algeria.
