Abstract

To improve the mechanical properties of the rolling body surface of wind power bearings, extend its service life. In this study, a large-scale molecular/atomic parallel processor LAMMPS was introduced, and then the process of magnetron sputtering technology in the preparation of DLC/Ni-DLC thin films on the 42CrMo substrate material was simulated. The effects of deposition parameters such as sputtering temperature, sputtering voltage, deposition air pressure, and Ni doping on the residual stress, film base bonding, and organizational structure of the thin films were investigated. The simulation results were also verified experimentally by magnetron sputtering. The simulation results show that Ni doping and reasonable control of the deposition parameters can help reduce the residual stress and improve the bonding strength of the film by changing the film organization.

Abstract

This work presents a novel approach to corrosion inhibition through the creation of a groundbreaking hexafunctional phosphorus epoxy resin, namely phosphorus trimethylene dianiline hexaglycidyl (HGTMDAP). This innovative material is synthesized via a two-step process, initiating with a grafting reaction between methylene dianiline and phosphorus trichloride, followed by the addition of epichlorohydrin to yield the hexafunctional resin. The unique structural intricacies of this material were elucidated using advanced microscopic characterization techniques such as FTIR, 1H, and 13C NMR. Furthermore, we dove into the exploration of the anticorrosive efficacy of this novel epoxy resin, specifically for metal, leveraging an array of evaluation methods, including EIS, PDP, isothermal adsorption model, thermodynamics, EFM, and the cutting-edge DFT, MC and MD simulations. To explore surface adsorption mechanism of the medium, comprising the metallic material, HGTMDAP resin, and 1.0 M HCl, it was employed sophisticated techniques such as SEM and EDS. This enabled us to decode the surface structure and chemical composition of the sample, providing us with a deeper understanding of the adsorption process and the mechanics of corrosion prevention. Our findings from the electrochemical tests suggest that an increase in the concentration of HGTMDAP significantly enhances protection ability. Interestingly, EIS demonstrated an impressive inhibition efficiency of 96.3% at the optimal concentration (10− 3 M) of HGTMDAP epoxy resin. Polarization results further corroborated that this advanced macromolecular binder serves as a mixed inhibitor. The Langmuir model, which posits that the epoxy resin forms a defender film on the metal surface, was validated in our study. We also utilized kinetic thermodynamic parameter estimation to further evaluate inhibitor adsorption phenomena. Finally, it was ventured into unchartered territory by describing the electronic and adsorption properties of the HGTMDAP epoxy resin using DFT, MC and MD simulations, paving the way for future research in this domain. Through our innovative approach, we have opened up new possibilities in the field of corrosion inhibition.
Modified constraint-induced movement therapy for lower limb intervention on patients with stroke: A Scoping Review

Published: January 2024

Abstract

Following the successful application of Constraint-Induced Movement Therapy (CIMT) in upper extremity rehabilitation for stroke patients, modified CIMT (mCIMT) has been introduced for lower extremity training in stroke patients. However, there is not enough evidence to prove its effectiveness in lower extremity rehabilitation. The diverse protocols of mCIMT present challenges in determining the superior approach for enhancing dyskinesia recovery. This study seeks to assess the safety and efficacy of mCIMT in lower extremity training for stroke patients and explores the essential components of mCIMT protocols to formulate an appropriate mCIMT plan for stroke patients. A literature search, following the PRISMA guidelines, was performed across four databases (PubMed, Web of Science, Scopus, PEDro) to identify clinical trials involving adult stroke patients receiving mCIMT for lower extremity movement disorders. The methodological quality of the included studies was evaluated using classifications based on study designs. According to predetermined inclusion and exclusion criteria, this review included 36 studies involving 931 patients. No serious adverse events were reported. The studies indicated that mCIMT significantly improves motor function, functional mobility, balance, lower extremity strength, weight-bearing, and walking ability. Five main types of constraint were identified. Dosage metrics include task repetition count and training duration. The use of transfer packages facilitated the translation of training effects into daily life. mCIMT for lower extremity functional recovery in stroke patients is deemed safe and feasible, contributing to the improvement of lower extremity functional impairments in stroke patients. Constraint devices are considered unsafe and unnecessary. Therefore, behavioural constraints are recommended. The repetition count of tasks is a suitable metric for assessing mCIMT dosage, and protocols with transfer packages enhance efficacy and sustainability. mCIMT holds broad prospects in stroke rehabilitation, with the need for individualized adjustments based on patient conditions to enhance effectiveness and practical value.

Authors: Nedzvetska Olga V. , Pastukh Uliana A. , Pastukh Irina V. 
Published: January 2024

Abstract
Purpose. The aim was to study the effect of the course of melatonin (M) injections on morphological changes in the ciliary body (CB) of rabbits with experimental hypopinealism.
Methodology. The experimental study was carried out on rabbits in compliance with the Law of Ukraine “On the Protection of Animals from Cruelty” No. 3447-IV (Kyiv, 2006) and the "European Convention for the Protection of Vertebrate Animals Used for Experimental and Other Scientific Purposes" (Strasbourg, 1985). Hypopinealism in animals was achieved by keeping them under conditions of round-the-clock illumination (RCI). The groups were: 1) the control group (CG) - 23 intact animals, which were in conditions of natural change of day and night; 2) a group with hypopinealism (HG) - 32 rabbits that were in the RCI; 3) the HG+M group - 29 rabbits that were in the RCI, but before being withdrawn from the experiment, received a course of injections of M for 14 days. Depending on the duration of the experiment, subgroups were identified: a) 3-5 months; b) 8-12 months. The concentration of M in the blood was determined by enzyme immunoassay. A morphological study of the enucleated eyeballs of animals was carried out with a morphometric analysis using the “fields” method.
Results. Influenced by RCI night production of M decreased to 62.26±5.27 pmol/l, compared to the control (369.45±14.35 pmol/l; p<0.005).
After 3-5 months of RCI, the average relative area of the vessels (ARAV) indicator in the morphometric study in the HG+M3-5 subgroup (15.32±0.37%) is lower than the HG3-5 indicator (17.71±0.43%; p<0.005), and significantly exceeds the indicator CG3-5 (4.70±0.19%; p<0.005); the average thickness of the vascular wall (ATVW) indicator (81.14±3.81×10-6 m) increased compared to CG1-2 (51.31±1.22×10-6 m, р<0.005), and decreased compared to HG3-5 (87.61±3.90×10-6 m; p<0.005). After 18-19 months in the subgroup HG+M18-19, the ARAV indicator decreases to 4.10±0.19%; (p<0.005) and is similar to the indicators of groups CG18-19 and HG18-1(4.22±0.17% and 4.01±0.19%; p<0.05). The indicator of MVWT increased (173.01±6.91×10-6 m), not differing from the HG18-19 indicator (177.51±7.32×10-6 m; p>0.05), but remaining higher than the CG18-19 indicator (101.91±4.42×10-6 m; р<0.005).
Conclusion. In animals with M deficiency after 18-19 months of RCI in the CB, the phenomena of vascular hyperemia and dyscirculatory disorders disappear completely, and pronounced sclerotic changes appear. There is a significant thickening of the walls of small arteries and veins due to sclerosis, which leads to a significant increase in ATVW. Vascular desolation is characterized by a significant decrease in the ARAV index. The course of M injections reduces edema and vascular disorders in the early stages of the RCI experiment for up to 5 months. After 18-19 months of RCI, apparently due to irreversible changes in blood vessels, the course of M has no therapeutic effect.
Temporomandibular joint discectomy. A long-term retrospective follow-up on the patient perspective.
Authors: Bäckström Esmeralda , Wänman Anders , Sjöström Mats 
Published: January 2024

Abstract
Purpose
To retrospectively evaluate long-term outcomes after temporomandibular joint (TMJ) discectomy.
Methods
Included patients (n = 64) had undergone discectomy during 1989–1998 at Umeå University Hospital. A questionnaire was used to evaluate pre- and postoperative symptoms, postoperative complications, general pain, and subjective opinion about the outcome of the surgery.
Results
The results are based on responses from 47 patients (40 women/7 men), including 36 (30 women/6 men) who completed the questionnaire and 11 (10 women/1 man) who were contacted by telephone and answered selected questions. Seventeen patients were excluded because of death, a move abroad, declining to participate, or no available patient information. Among the respondents, 41 (87%) were satisfied with the results, five (11%) were unsatisfied, and one (2%) patient did not answer the question. The results showed a significant long-term improvement in locking, clicking/crepitation, and pain when chewing or opening the jaw (p = 0.001). The prevalence of headaches had decreased significantly at follow-up (p = 0.001). Reported impaired jaw-opening capacity showed no significant improvement (p = 0.08). Of the 47 respondents, 19 (40%) had asked for additional treatment after the discectomy, and six of the 19 patients (13%) had undergone more surgery of the joint.
Conclusion
The results of this retrospective long-term follow-up study indicate that TMJ discectomy has a high success rate, as most patients were satisfied with the postoperative results. Discectomy is thus an effective surgical intervention for patients with disabling TMJ pain and dysfunction when conservative interventions have been unsuccessful.

Published: January 2024

Abstract

Background/Objectives: There is a lack of certainty in dietary prescription for individuals with inflammatory bowel disease (IBD) due to heterogeneity in studies to date. The aim of this study was to investigate the efficacy on disease activity of a modified anti-inflammatory dietary pattern purposely designed to reduce intake of food additives (IBD-MAID), compared to standard care, in adults with IBD.
Subject/Methods: Adults with IBD were randomised to IBD-MAID (meals provided) [n=29] or general healthy eating (GHE) [n=29] for 8 weeks. Disease activity, faecal calprotectin (FC), C-reactive protein (CRP), symptoms and quality of life (S&QOL) were assessed using validated tools.
Results:The IBD-MAID was well tolerated and adhered to (92% adherence). At week 8, there was no statistically significant difference in change from baseline in outcome measures between groups. However, baseline to week 8 analysis indicated: 1) statistically significant improvements in S (p = 0.001) & QOL (p = 0.004), FC (p = 0.007) and Crohn’s disease activity ( p = 0.03) but not ulcerative colitis, in individuals following the IBD-MAID and 2) statistically significant improvement in QOL in individuals receiving GHE (p = 0.015). Correlation analysis revealed a r decrease in food additives intake was associated with statistically significant improvements in FC, S & QOL and alignment of anti-inflammatory dietary principles with improvements in QOL.
Conclusion: The IBD-MAID was well tolerated. The most novel finding pertains to the correlation between reducedfood additives intake and improvements in inflammatory markers, S&QOL. Further research is needed to explore the effects of food additives exposure on IBD course.

Divorce and Housing Price Shocks in Mexico
Authors: Jauregui Andres , Avalos Antonio , España-Nájera Annabella 
Published: January 2024

Abstract
Economic explanations of divorce are centered on the idea that individuals make marital decisions based on potential financial benefits. This paper aligns with this perspective and extends a growing literature on the impact of house price shocks on divorce rates (Rainer & Smith, 2010; Farnham et al., 2011; Harknett & Schneider, 2012; Klein, 2017) by analyzing the impact of unexpected house price shocks on Mexico's divorce rates over the past 15 years. Our research presents two novel contributions. Firstly, it focuses on Mexico, where we posit that factors like economic informality, family networks, inequality, and migration shape individuals' marital calculations distinctly from more developed countries. Secondly, we test how life circumstances, specifically the duration of marriage and socioeconomic status moderate individuals’ reactions to unexpected house price changes. Utilizing newly compiled state-level data, our findings underscore the importance of context. Notably, the duration of marriage emerges as a critical factor in how individuals respond to unexpected house price shocks. Consistent with the literature, we find that unexpected positive house price shocks stabilize marriages (Klein, 2017), particularly for marriages of longer duration. In contrast, our analysis reveals that unexpected negative house price shocks do not have a statistically significant impact on divorce rates in Mexican states. As hypothesized, couples with lower socioeconomic status demonstrate a higher propensity to divorce during unexpected positive housing price shocks.

Authors: Cheng Xiaoqiang , Yao Yilun , Liu Kang , Wu Lei , Yang Wengbo 
Published: January 2024

Abstract
Objective
To introduce the method and experience of treating large segmental tibial bone defect by taking large iliac crest bone graft.
Methods
From January 2020 to January 2022, iliac crest bone grafting was performed in 20 patients (10 men and 10 women) with large segmental tibial bone defect. The mean length of bone defect was 13.59 ± 3.41. Bilateral iliac crest grafts were harvested, including the inner and outer plates of the iliac crest and iliac spine. The cortical part was trimmed and shaped by cortical bone screws to match the bone defect at the recipient site. Locking plate was used to fix the graft-host complex, supplemented with reconstruction plate to increase stability when necessary. Bone healing was evaluated by cortical bone fusion on radiographs at follow-up, iliac pain was assessed by VAS score, and lower limb function was assessed by ODI score. Complications were also taken into consideration.
Results
The average follow-up time was 27.4 ± 5.6 (Range 24–33 months), the mean VAS score was 8.8 ± 1.9, the mean ODI score was 11.1 ± 1.8, and the number of cortical bone fusion in the bone graft area was 3.5 ± 0.5. No nonunion, shift or fracture was found in all cases. No infection and bone resorption were observed that need secondary surgery. One patient had dorsiflexion weakness of the great toe. Hypoesthesia of the dorsal foot was observed in 2 patients. Ankle stiffness and edema occurred in 3 patients. Complications were significantly improved by physical therapy and rehabilitation training.
Conclusion
For the cases of large segmental tibial bone defects, the treatment methods are various. In this paper, we have obtained satisfactory results by using large iliac bone graft to treat bone defect. This approach can not only restore the integrity of the tibia, but also obtain good stability with internal fixation, and surgical skills are more likely to be mastered by clinicians. Therefore, it provides an alternative surgical method for clinicians.
Dynamical analysis, circuit design, synchronization, and Arduino UNO implementation of a new 7D hyperchaotic system
Authors: Kopp Michael 
Published: January 2024

Abstract
In this paper, we introduce a novel multidimensional 7D hyperchaotic system. We conduct an analysis of this innovative 7D dynamic system, focusing on determining Lyapunov exponents, constructing bifurcation diagrams, and identifying equilibrium points along with their corresponding stability conditions. Through computer modeling of the 7D hyperchaotic system in Matlab-Simulink and Labview, we obtain phase portraits of numerous strange attractors. Subsequently, the electronic circuit for the new 7D chaos generator was developed using Multisim software, showcasing behavior similar to the Matlab-Simulink and LabVIEW models. Furthermore, we study the synchronization problem for two identical 7D hyperchaotic systems, employing a nonlinear active control method. To depict the novel 7D hyperchaotic system, we utilized an Arduino UNO board and incorporated seven light-emitting diodes (LEDs). Additionally, we showcased the ability to replicate the new 7D hyperchaotic system within the Proteus 8 environment by employing the Arduino UNO microcontroller.
Predicting Adults' Income using Naive Bayes Classifier
Authors: Elrahman Ahmed Abd 
Published: January 2024

Abstract
Predicting the income level of adults is an important task in understanding the socio-economic dynamics and identifying key factors that contribute to income disparities. This paper proposes to build a predictive model to predict the income levels of adults using the Naive Bayes classifier. To commence the analysis, we preprocess the dataset by addressing missing values and encoding categorical variables, Subsequently, we train a Naive Bayes classifier on a labeled training set, with income levels as the target variable. To evaluate the performance of the Naive Bayes classifier, we employ standard evaluation metrics such as accuracy, precision, recall, and F1-score. Our experimental findings demonstrate the potential of the Naive Bayes classifier in predicting adults' income based on socio-demographic factors. Based on the findings of the experiments, the Naive Bayesian classifier has an accuracy equal to 80.83%.

Published: January 2024

Abstract
As global climate patterns evolve, it becomes increasingly vital to understand the seasonal factors influencing nutrient concentrations in lake ecosystems. The complex role of winter dynamics in lakes relative to climate and ecosystem processes can influence nutrient cycling and phytoplankton dynamics. In this study we address this knowledge gap by investigating seasonal variations in water column nutrient concentrations, climatic conditions, and ice phenology in a small shallow hypereutrophic lake in south-central Québec, Canada. Water column nutrients were sampled from October 2009 to September 2020 at two locations (Lake Inlet and Lake Outlet). The results of this study emphasize the variability in ice-on duration (ranging from 102 to 166 days) and its significant correlation with dissolved inorganic nitrogen accumulation during the ice-on period over a decadal timestep. Notable shifts in phytoplankton composition between ice-on and ice-off periods were observed, accompanied by a significant long-term decline in species richness. Crucially, the accumulation of nitrate-nitrite during the ice-covered period was correlated with the relative proportion of cyanobacteria in the subsequent growing season. This study underscores the essential yet limited understanding of winter limnological characteristics and their pivotal role in the seasonal dynamics of nutrient cycling, and phytoplankton and cyanobacteria dynamics particularly amid ongoing climate changes.
Hydrodynamics of a relativistic charged fluid in the presence of a periodically modulated chemical potential
Authors: Chagnet Nicolas , Schalm Koenraad 
Published: January 2024

We study charged hydrodynamics in a periodic lattice background. Fluctuations are Bloch waves rather than single momentum Fourier modes. At boundaries of the unit cell where hydrodynamic fluctuations are formally degenerate with their Umklapped copy, level repulsion occurs. Novel mode mixings between charge, sound, and their Umklapped copies appear at finite chemical potential - both at zero and finite momentum. We provide explicit examples for an ionic lattice, i.e. a periodic external chemical potential, and verify our results with numerical computations in fluid-gravity duality.

Abstract

Southeast Asia is vulnerable to climate change with over half of its population already being impacted by drought, flooding, and rise in sea levels recently. This work reviews the current water resource challenges in Indonesia, prone to the rising impacts of climate change. A baseline assessment of Indonesia's water and drinking water resources related to its original sources is presented. In response to a growing concern over chronic challenges that undermine water supply nationwide, this study analyses drinking water safety supervision. To accomplish this, a literature survey (100 studies published during the 2000–2023 period) was performed to identify regional groundwater resources sustainability and water security issues. Among the main findings of this study, only 10% of rainfall infiltrates to the groundwater, while 70% of its rivers are heavily polluted by domestic waste. During the study period, water availability decreased to 1,200 m3/year in 2020, with only 35% of the resources being economically feasible for reuse. The water supply deficit in Indonesia was estimated to be 5.5 hm3/year with roughly 67% of the population's water demand satisfied in 2021. Although this deficit might be fulfilled with private vendors, water supply/demand forecasts in 2030 suggest that the gap could not be closed by increasing water supply.
