Published: September 2023

Abstract

This work aims to develop LED luminary intensity control (LIC) modules that are energy efficient. In this paper, we propose various modules for varying luminary intensity (LI) based on (i) Zone timer-based intensity control (ZTIC), (ii) ZTIC with motion detection (ZTICMD), (iii) Authorized User LIC (AULIC) (iv) Hybrid mode of LIC (HMLIC), (v) HMLIC with motion detection (HMLICMD) (vi) Intensity control based on priority (ICP). The motion detection mode supports the motion of vehicles with high speed. In hybrid mode, motion detection saves 60–85% of energy and helps to decrease carbon footprints. The modules use simple circuits. These modules use for different outdoor lighting applications.

Abstract

Aiming at the problem of the failure of bearing lubrication caused by the entry of fine dust into the spacecraft, a molecular dynamic simulation method was proposed to study the wear characteristics of the bearing lubricating film. Firstly, the atomic model of MoS2 thin film is established, and the motion state of dust particles on the surface of MoS2 thin film is divided (sliding abrasive and rotating abrasive). Secondly, the characteristics of sliding and rotating abrasive wear are studied by applying different loads to the abrasives. Finally, the surface structure of the substrate was changed to explore the adsorption and wear characteristics of the one-dimensional rough substrate. The following conclusions are obtained: 1) sliding abrasive and rotating abrasive have different wear mechanisms. The wear of sliding abrasive originates from the accumulation and release of tangential force. The main source of wear in rotating abrasive is the release of tangential force and the action of tangential force caused by rolling; 2) The relationship between sliding friction and rolling friction at the atomic scale is the same as that at the macroscopic scale. Rolling friction is much less friction than sliding friction. Rolling friction causes less damage to the film than sliding friction; 3) The one-dimensional rough substrate reduces the contact area between the film and the film, resulting in a decrease in the adsorption between the film and the substrate. The asperity structure of rough substrates reduces the lubricity of the film compared to smooth substrates.

Abstract

In this study, actual piggery wastewater was treated by aerobic granular sludge (AGS) in a sequencing batch reactor (SBR) and verified its treatment capacity. At the same time, the non-filamentous bulking was controlled through a series of measures. The results showed that on the 13th day of operation, the AGS was formed with a particle size of 611.4 µm. The highest removal rates of ammonia nitrogen (NH4+-N), chemical oxygen demand (COD), total nitrogen (TN), and total phosphorous (TP) by the AGS were 99%, 99%, 90%, and 96%, respectively. After 32 days of reactor operation, an overgrowth of zoogloea led to increased polysaccharides (PS) secretion from the extracellular polymeric substances (EPS), resulting in a non-filamentous bulking. Adjusting the carbon source concentration to change the organic loading rate (OLR) in SBR, which increased from 4 kg COD m3·d− 1 to 16 kg COD m3·d− 1, then decreased to 5.6 kg COD m3·d− 1, this value is considered suitable for the long-term growth of AGS. During this period, the non-filamentous bulking was solved by reducing water temperature, increasing hydraulic shear force and selective pressure, and manual screening. Finally, the sludge bulking was reduced on the 60th day. The experimental results indicated that the sludge bulking has little effect on the removal of COD by AGS, but has a significant impact on the nitrogen and phosphorus removal effect. In the process of sludge granulation, species diversity, and microbial biomass in the sludge decreased, especially before and after controlling sludge bulking, and dominant microbial species changed significantly.

Abstract
Insect pests are a major constraint to cucumber production in Nigeria. The study tested a commercial formulation of Beauvaria bassiana, a non-residual bio-pesticide, for bioactivity against the insect pests of cucumber. B. bassiana is a cosmopolitan fungus which inhabits the soil naturally. The experiment was carried out in the late season 2021 and early season 2022 to establish the most effective and profitable optimum rate and frequency of B. bassiana application for optimum insect pest management on cucumber. The densities of Aulacophora hilaris, Aulacophora nigripennis, Aulacophora foveicolis, Epilachna chrysomelina, Coridus viduatus and Bactrocera cucurbitae obtained in both seasons were significantly lower in treated plots than the control plots. Percent leaf damage was similar across the treated plots while the control plots had the highest (60.64% and 47.64%) percent leaf damage in both seasons. Also, highest (62.70% and 61.97%) percent fruit damage was obtained in the control plots relative to the treated plots. Cucumber yield was significantly higher in the plot sprayed at 8.00 kg/ha once a- week (546.67% and 514.29%) compared to other treated plots. Highest profitability (1.00 and 1.00) was obtained in the plots sprayed with B. bassiana at 8.00 kg/ha once-a-week followed by 1.05 and 0.95 in the plots sprayed at 6.00 kg/ha once-in-two-weeks.

Abstract
Background: Acquired brain injury (ABI) often leads to persisting somatic, cognitive and social impairments. Cognitive impairments of processing speed, sustained attention and working memory are frequently reported, and may negatively affect activities of daily living and quality of life. Rehabilitation efforts aiming to retrain these cognitive functions have often consisted of computerized training programs. However, few studies have demonstrated effects that transfer beyond the trained tasks. There is a growing optimism regarding the potential usefulness of Virtual Reality (VR) in cognitive rehabilitation. The research literature is sparse, and existing studies are characterized by considerable methodological weaknesses. There is also a lack of knowledge about the acceptance and tolerability of VR as an intervention method for people with ABI. The present study aims to investigate whether playing a commercially available VR-game is effective in training cognitive functions after ABI, and to explore if the possible effects transfer into everyday functioning.
Methods: One hundred participants (18-65 years), with a verified ABI, impairments of processing speed/attention, and/or working memory, and minimum 12 months post injury will be recruited. Participants with severe aphasia, apraxia, visual neglect, epilepsy and severe mental illness will be excluded.
Participants will be randomized into two parallel groups; 1) an intervention group playing a commercial VR game taxing processing speed, working memory and sustained attention, 2) an active control group receiving psychoeducation regarding compensatory strategies, and general cognitive training tasks such as crossword puzzles or sudoku. The intervention period is five weeks. The VR-group will be asked to train at home for 30 minutes five days per week.
Each participant will be assessed at baseline with neuropsychological tests and questionnaires, after the end of the intervention (5 weeks), and 16 weeks after baseline. After the end of the intervention period, focus group interviews will be conducted with 10 of the participants in the intervention group, in order to investigate acceptance and tolerability of VR as a training method.
Discussion: This study will contribute to improved understanding of how VR is tolerated and experienced by the ABI population. If proven effective, the study can contribute with new rehabilitation methods that persons with ABI can utilize in a home setting, after the post-acute rehabilitation has ended.

Abstract
In order to realize the effective utilization of overproduced Fructus Mori. In this study, different fermentation strains (Yeast, Lactobacillus bulgaricus and Monascus) were used as starters to ferment Fructus Mori. The results showed that the maximum Fructus Mori polysaccharides yield could reach 6.32% under the optimal conditions (liquid-solid ratio of 28.58 mL/g, inoculum volume of 4.93, temperature of 302.99 K and time of 83.78 h). In antioxidant studies, Fructus Mori polysaccharides had good scavenging ability on four free radicals (DPPH free radicals, ·OH free radicals, ABTS free radicals and superoxide anions). Moreover, Fructus Mori polysaccharide had strong antibacterial activity against 6 tested pathogens, and the order of antibacterial effect was Staphylococcus aureus (36.5±1.26 mm)>Bacillus subtilis (33.5±1.12 mm)> Listeria monocytogenes (29.5±1.03 mm)> Escherichia coli (25.9±1.35 mm)> Salmonella (21.5±1.06 mm)> Vibrio parahaemolyticus (15.8±1.16 mm) with the Fructus Moripolysaccharides concentration of 40 mg/mL. The research results can provide a certain application value for the functional development and utilization of Fructus Mori polysaccharides.

Published: September 2023

Abstract
In this paper, the near-field lightwave characteristics of an arrayed silicon nano-cone-tip optical antenna (NOA) covered by a common metal film, which can be viewed as a featured quantum dot (QD), are carefully investigated. A dipole net-charge distribution closely correlated with the surface lightwaves excited over the antennas by incident lasers with a central wavelength of 633 nm, is clearly observed. An obvious Coulomb blockade from the apex apparently influencing the net-charge converging over the surface of NOA, is verified, which can also be predicted by the simulations according to surface standing waves across the apex node. The antinodes of the surface net-charge instantaneous distribution are already pushed away from the normal location owing to the apex Coulomb blockade, so as to present a distorted waveform different from traditional standing wave modes. The tip proximity effect leading to a relatively weak net-charge converging over surrounding planar facet and adjacent NOAs, is also discovered.

Published: September 2023

Abstract

Background:Anti-signal recognition particle (anti-SRP) antibodies are one of the two most commonly identified antibodies in immune-mediated necrotizing myopathies (IMNMs), a disease characterized by proximal muscular weakness. Anti-SRP-positive IMNMs predominantly affect middle-aged women; extra-muscular manifestations, such as interstitial lung disease (ILD), are not frequent and often mild. Malignancy is not a major concern for patients with IMNMs, especially those who are anti-SRP-positive. Case presentation:We present the case of a 64-year-old male who tested positive for anti-SRP antibodies and presented with ILDinstead of myopathy. This was accompanied by metastatic duodenal adenocarcinoma, and the patient experienced rapidly progressive interstitial lung disease (RP-ILD) during anticancer therapy. We chose low-dose immunosuppressive therapy after surgical removal of the metastatic cancerous lesion. The patient exhibited a positive response, whose respiratory condition gradually improved throughout the 2-year follow-up period. But the primary lesion appeared two years later than the site of metastasis, and the patient developed extensive metastases finally.Conclusions:The rare form of ILD in this patient highlights the significance of cancer screening and surveillance in atypical anti-SRP-positive patients. Low-dose immunosuppressive therapy following anticancer therapy resulted in significant improvement in ILD, serving as a treatment reference for paraneoplastic RP-ILD.
Advancing Reservoir Characterization: A Comparative Analysis of Xgboost and Ann for Accurate Porosity Prediction
Authors: Adekanye Damilola Israel , Abe Sunday James 
Published: September 2023

Abstract
This study presents a comprehensive analysis of porosity prediction in reservoir characterization using two powerful machine learning algorithms, XGBoost and Artificial Neural Networks (ANN). Well log data, including GR log, resistivity log, density log, sonic log, neutron log, and por_insitu, were employed for training and validation, with the latter serving as core data for porosity at identical depths. The initial XGBoost prediction yielded an accuracy of 57.54%, prompting the implementation of performance metrics and hyperparameter tuning. Through these optimizations, the XGBoost model's accuracy skyrocketed to an impressive 96.75%, with refined performance metrics, including MAE of 0.766158, MSE of 1.047763, and RMSLE of 0.038324. Leveraging the well log data and core data validation, the XGBoost model demonstrated outstanding accuracy levels, holding immense promise for reservoir characterization and hydrocarbon exploration. On the other hand, ANN model underwent data standardization and architecture experimentation, ultimately finding the "tanh" model with ten hidden layers to be the best performer. This model achieved a mean absolute error (MAE) of 1.87 for the train data and 4.08 for the test data. Comparing the two models, the XGBoost model clearly outperformed the ANN model in accuracy for porosity prediction, making it the preferred choice for reservoir applications. The project's success highlights the efficacy of XGBoost in handling complex geological data and its ability to deliver accurate predictions for porosity. Additionally, the ANN model's performance demonstrates the importance of optimizing network architecture and activation functions in achieving accurate results. The findings of this study underscore the significance of machine learning in reservoir characterization, offering valuable insights for decision-making processes in the petroleum industry. The report provides valuable insights for reservoir engineers, geoscientists, and data scientists, offering a foundation for future advancements in reservoir characterization and resource exploration.
Interrogating Site Dependent Kinetics over SiO2-Supported Pt Nanoparticles
Authors: Reece Christian , Kim Taek-Seung , O'Connor Christopher 
Published: September 2023

Abstract
A detailed knowledge of reaction kinetics is key to the development of new more efficient heterogeneous catalytic processes. However, the ability to resolve site dependent kinetics has been largely limited to surface science experiments on model systems. Herein, we can bypass the pressure, materials, and temperature gaps, resolving and quantifying two distinct pathways for CO oxidation over SiO2-supported 2 nm Pt nanoparticles under operando conditions. We find that the pathway distribution directly correlates with the distribution of well-coordinated (e.g., terrace) and under-coordinated (e.g., edge, vertex) CO adsorption sites on the 2 nm Pt nanoparticles as measured by in situ DRIFTS. We conclude that well-coordinated sites follow classic Langmuir-Hinshelwood kinetics, but under-coordinated sites follow non-standard kinetics with CO oxidation being barrierless but conversely also slow. This fundamental method of kinetic site deconvolution is broadly applicable to other catalytic systems, affording bridging of the complexity gap in heterogeneous catalysis.
Wnt/β-catenin signaling pathways mediate monocrotaline-induced pulmonary arterial hypertension via glycolysis in rats
Authors: Meng Hui , Deng Yan , Liao Juan , Wu Dan-dan , Li Li-xiang , Chen Xing , Lan Wei‑Fang 
Published: September 2023

Abstract
Pulmonary arterial hypertension (PAH) is a progressive and life-threatening disease. Metabolic abnormalities and immune inflammation are deeply involved in pulmonary vascular remodeling and in the formation of PAH. Cumulative evidence indicates that β-catenin and abnormal glucose metabolism play an important role in the development of PAH, but the underlying mechanism is still elusive. To elucidate this mechanism, we first established a rat model of PAH and then treated some rats with a specific β-catenin inhibitor (XAV939). After examining the protein expression of β-catenin, levels of indicators of glucose metabolism, right ventricular pressure (RVSP) and pulmonary artery histopathology, we found that monocrotaline (MCT)-exposed rats had an increase in levels of glycolytic metabolism markers and that this phenomenon could be blocked by β-catenin inhibitors. This study demonstrated that Wnt/β-catenin signaling promotes the inflammatory response involved in pulmonary vascular remodeling and participates in the formation of PAH by regulating glycolysis in macrophages. Inhibition of Wnt/β-catenin signaling pathways could improve the progression of PAH, which may provide novel therapeutic targets for the treatment of PAH.

Abstract
Background
Social and structural determinants of health (SDoH) are associated with tuberculosis (TB) outcomes but often unaddressed in TB care programs. We sought to describe the mechanism by which SDoH impact completion of TB diagnostic evaluation in Uganda using an implementation science framework rooted in behavioral theory.
Methods
Trained research staff interviewed 24 purposively sampled adults undergoing TB diagnostic evaluation at six community health centers in Uganda between February-August 2019. Framework analysis was used to construct themes linked to SDoH across the TB diagnostic evaluation cascade of care. Themes were then mapped to domains of the capability, opportunity, and motivation behavior change model (COM-B).
Results
Barriers related to SDoH were identified across the diagnostic evaluation cascade of care and associated with domains central to uptake of testing and treatment. These included: limited knowledge about TB diagnosis and treatment (psychological capability); low socioeconomic status and competing financial priorities (physical opportunity); internalized and anticipated stigma of TB diagnosis, lack of social support programs and limited social support/social capital (social opportunity, reflective motivation); trust (or distrust) in the government health facility to provide quality care (reflective motivation); and fear and shame about worsening poverty (automatic motivation). Facilitators to engagement with the TB cascade of care included encouragement from friends and family to seek testing (automatic motivation, social opportunity), and trust that healthcare providers were acting in their best interests (social opportunity).
Conclusions
Biomedical interventions alone are unlikely to address the spectrum of SDoH-related barriers to completion of TB diagnostic evaluation. Linking barriers to a behavior change model such as COM-B may help guide the design and evaluation of appropriate people-centered strategies that integrate social and economic supports with clinical and public health programs or services.
Use of transradial access to install two sequential stents for pseudoaneurysms along the celiac artery and common hepatic artery axes: A case report
Authors: Ghosh Abheek , Agnihotri Tanvir , Lee Sean , Akhter Nabeel 
Published: September 2023

Abstract
Background
Transfemoral access (TFA) is the usual method for stenting visceral aneurysms. Here, we utilized transradial access (TRA) to sequentially place two stents for pseudoaneurysms in the celiac artery (CA) and common hepatic artery (CHA).
Case Presentation
58-yo male with pancreatic cancer s/p distal pancreatectomy presents with decreasing hemoglobin. Imaging showed evidence of intraperitoneal bleeding secondary to CA and CHA pseudoaneurysms. Due to coagulopathic concerns, stenting was pursued along these axes via TRA. Left radial artery (RA) sonogram revealed a Barbeau B waveform. After the left RA was accessed, a 5-Fr slender sheath was placed over a 0.018 wire. Over Bentson wire, a 5-Fr pigtail catheter was then placed into the abdominal aorta. Next, a catheter was exchanged over wire for a 5-Fr Ultimate catheter, and the superior mesenteric artery was selected, followed by the CA. Truselect microcatheter, assisted by fathom wire, was then placed into the CHA and right hepatic artery (HA). A microcatheter was placed deep into the right HA branch; a V18 exchange-length wire was placed through the microcatheter into that branch. A 6-Fr radial sheath was placed over the wire. Two 6mm x 5cm covered self-expanding Viabahn stents were then sequentially placed. The first stent covered the pseudoaneurysm in the CHA; the second stent extended from the first into the celiac axis. An Ultimate catheter was later placed in the celiac axis. Post-stenting arteriogram and angiogram revealed patent stents in the CA and CHA, with no evidence of active arterial extravasation.
Conclusion
TRA may be valuable in stenting visceral aneurysms/pseudoaneurysms.
