Product Inspection Methodology via Deep Learning: An Overview

In this study, we present a framework for product quality inspection based on deep learning techniques. First, we categorize several deep learning models that can be applied to product inspection systems. In addition, we explain the steps for building a deep-learning-based inspection system in detail. Second, we address connection schemes that efficiently link deep learning models to product inspection systems. Finally, we propose an effective method that can maintain and enhance a product inspection system according to improvement goals of the existing product inspection systems. The proposed system is observed to possess good system maintenance and stability owing to the proposed methods. All the proposed methods are integrated into a unified framework and we provide detailed explanations of each proposed method. In order to verify the effectiveness of the proposed system, we compare and analyze the performance of the methods in various test scenarios. We expect that our study will provide useful guidelines to readers who desire to implement deep-learning-based systems for product inspection.
Comparison of different convolutional neural network activation functions and methods for building ensembles

Recently, much attention has been devoted to finding highly efficient and powerful activation functions for CNN layers. Because activation functions inject different nonlinearities between layers that affect performance, varying them is one method for building robust ensembles of CNNs. The objective of this study is to examine the performance of CNN ensembles made with different activation functions, including six new ones presented here: 2D Mexican ReLU, TanELU, MeLU+GaLU, Symmetric MeLU, Symmetric GaLU, and Flexible MeLU. The highest performing ensemble was built with CNNs having different activation layers that randomly replaced the standard ReLU. A comprehensive evaluation of the proposed approach was conducted across fifteen biomedical data sets representing various classification tasks. The proposed method was tested on two basic CNN architectures: Vgg16 and ResNet50. Results demonstrate the superiority in performance of this approach. The MATLAB source code for this study will be available at https://github.com/LorisNanni.
Evaluation of Oxygen Transfer at Stepped Cascade Aerators

Dissolved oxygen content in water is one of the most important water quality parameters. In most wastewater treatment plans a lot of oxygen is utilized. Thus it becomes necessary to add oxygen to water in order to comply with the minimum dissolved oxygen concentration in the State's Water Pollution Control Regulations before the treated water is discharged into rivers or streams. One of the most cost effective post-aeration designs is a stepped-cascade aerator. There are many existing equations for modeling the oxygen transfer at stepped cascade aerators. These equations are mostly empirical and limited to certain situations. Existing models are evaluated against field data taken at four wastewater treatment plants. All models are found to need improvement. The need for a new equation specifically for stepped cascade aerators is evident since existing models were not developed for stepped cascade aerators, but for weirs or other hydraulic structures.
On the Microstructural, Mechanical and Tribological Properties of Mo-Se-C Coatings and Their Potential for Friction Reduction against Rubber

Friction and wear contribute to high energetic losses that reduce the efficiency of mechanical systems. However, carbon alloyed transition metal dichalcogenide (TMD-C) coatings possess low friction coefficients in diverse environments and can self-adapt to various sliding conditions. Hence, in this investigation, a semi-industrial magnetron sputtering device, operated in direct current mode (DC), is utilized to deposit several molybdenum-selenium-carbon (Mo-Se-C) coatings with a carbon content up to 60 atomic % (at. %). Then, the carbon content influence on the final properties of the films is analysed using several structural, mechanical and tribological characterization techniques. With an increasing carbon content in the Mo-Se-C films, lower Se/Mo ratio, porosity and roughness appeared, while the hardness and compactness increased. Pin-on-disk (POD) experiments performed in humid air disclosed that the Mo-Se-C vs. nitrile butadiene rubber (NBR) friction is higher than Mo-Se-C vs. steel friction, and the coefficient of friction (CoF) is higher at 25 °C than at 200 °C, for both steel and NBR countersurfaces. In terms of wear, the Mo-Se-C coatings with 51 at. % C showed the lowest specific wear rates of all carbon content films when sliding against steel. The study shows the potential of TMD-based coatings for friction and wear reduction sliding against rubber.
Waterborne polyurethanes and their properties

Anionomer-type waterborne polyurethanes (PUs) were obtained from poly(β-methyl-δ-valerolactone) glycol (PMVL) and isophorone diisocyanate, following a prepolymer mixing process. The soft-hard segment phase separation in response to the variations of composition and structure of PU has been studied from the dynamic mechanical measurements of the emulsion cast films. The structural variation included ionic and hard segment content, molecular weight of NCO-terminated prepolymer, and type and length of the soft segment. It was found that phase separation is more sensitive to the soft segment length, rather than the soft segment content. With only phase separation, the rubbery modulus was significant even with lower hard segment content. Phase separation was much more pronounced with PU from poly(tetramethylene adipate) glycol, rather than from PMVL and poly(caprolactone) © 1996 John Wiley & Sons, Inc.
The Effect of Irisin as a Metabolic Regulator and Its Therapeutic Potential for Obesity

Obesity is a worldwide health problem due to the imbalance of energy intake and energy expenditure. Irisin, a newly identified exercise-responsive myokine, which is produced by the proteolytic cleavage of fibronectin type III domain-containing protein 5 (FNDC5), has emerged as a promising therapeutic strategy to combat obesity and obesity-related complications. Various studies in mice have shown that irisin could respond to systematic exercise training and promote white-to-brown fat transdifferentiation, but the role and function of irisin in humans are controversial. In this review, we systematically introduced and analyzed the factors that may contribute to these inconsistent results. Furthermore, we also described the potential anti-inflammatory properties of irisin under a variety of inflammatory conditions. Finally, the review discussed the existing unresolved issues and controversies about irisin, including the transcription of the irisin precursor FNDC5 gene in humans, the cleavage site of the yet unknown proteolytic enzyme that cleaves irisin from FNDC5, and the reliability of irisin levels measured with available detection methods.
Association of antipsychotic use with raised eosinophil count

The current study aimed to assess the possibility of an association between first and second generation antipsychotic medication and raised eosinophil count. A total of 22 in-patients at the psychiatric unit of the University General Hospital ‘Attikon’, a tertiary hospital, were included in the present study. Patients had received antipsychotic monotherapy and did not have any co-morbidities or require additional treatments. Patients were monitored weekly and their eosinophil count was assessed. One-way ANOVA and summary measures analysis were applied to study the effect of time and medication type on the absolute eosinophil concentration (or relative percentage) for each patient. The differences in mean eosinophil concentrations or relative percentage by patient and time were also assessed. An increase in the absolute concentration and the relative percentage of eosinophils over time was observed in patients receiving Olanzapine, Haloperidol and Aripiprazole. However, there was no difference between individual medications. In conclusion, antipsychotics may be associated with increased eosinophil count over time; however, larger studies involving more patients and a longer follow-up are required to reach a definitive conclusion.
Therapeutic Efficacy and Safety of Safflower Injection in the Treatment of Acute Coronary Syndrome

Background Safflower injection (SFI), a popular Chinese patent drug, is commonly used to treat acute coronary syndromes (ACSs) in China. The research seeks to scientifically estimate the clinical efficacy of SFI for ACS patients. Methods Eight electronic databases were retrieved for eligible research from the founding date to September 8, 2020. Odds ratio (OR) was adopted to assess the total effective rate, ECG improvement, and adverse reaction, and mean difference (MD) was used for assessing the hemorheology indexes as well as the LVEF. Results Sixteen randomized controlled trials involving 1620 sufferers with ACS were incorporated. The outcomes showed that, in comparison to conventional medication alone, SFI combined with conventional treatment remarkably enhanced the total effective rate (OR = 3.66, 95% CI [2.73, 4.90], P < 0.00001), ECG improvement (OR = 2.85, 95% CI [2.04, 3.99], P < 0.00001), and LVEF (MD = 5.13, 95% CI [3.73, 6.53], P < 0.00001). Moreover, SFI combined with conventional treatment significantly decreased hemorheology indexes including BV (MD = −0.95, 95% CI [−1.76, −0.13], P=0.02), HCT (MD = −2.37, 95% CI [−3.25, −1.50], P < 0.00001), FIB (MD = −0.44, 95% CI [−0.60, −0.29], P < 0.00001), and PAR (OR = −7.65, 95% CI [−10.16, −5.14], P < 0.00001). However, no notable contrast was observed to link the experimental and the control team for PV (MD = −0.42, 95% CI [−0.83, 0.00], P=0.05) and adverse reactions (OR = 0.59, 95% CI [0.13, 2.74], P=0.50). Conclusion Despite the limitations that existed in this meta-analysis, the outcomes demonstrated that SFI and conventional combined medication is an effective and relatively safe therapy for ACS sufferers.
Low invasive estrous synchronization protocol for wild animals: an example with melengestrol acetate in brown brocket deer (Mazama gouazoubira)

Abstract Deer are sensitive to stressful stimuli by handling and their reproductive physiology could be altered by these procedures, making it necessary to develop less invasive protocols for ART. Melengestrol acetate (MGA), a synthetic progestin administered orally, appears as an alternative for estrous synchronization protocols (ESP), such as reported in cattle. Firstly, we compared two MGA doses (0.5 and 1.0 mg/day/animal), which would have suppression effect in estrous behavior (EB). Eight females were randomly and equally distributed in Group 1 (G1) and Group 2 (G2), which received 0.5 and 1.0 mg/day/animal respectively for 15 days (D1 to D15). Two cloprostenol (CP) applications were performed on D0 and D11. Estrus detection (ED) was performed every day. All females from G1 displayed estrus during treatment period, whereas all females from G2 displayed estrus after treatment, suggesting a suppressive effect of 1.0 mg in the EB. Once the suppressive MGA dose (1.0 mg) was defined, we used this dose for assessing ESP. The same eight females received 1.0 mg/animal for eight days (D-8 to D-1), followed by 0.25 mg of estradiol benzoate on D-8 and 265 μg of CP on D0. Feces for fecal progesterone metabolites (FPM) measurement were collected from D0 until seven days after the last day of estrus. Seven females displayed estrus between 12 and 72 h after CP application, which was followed by a significant increase in FPM levels (except female MG6), suggesting the formation of corpus luteum. After ED, females were placed with a fertile male to assess the fertility of the protocol. Pregnancy was confirmed by ultrasound 30 days after mating in 3/6 individuals. Although the low effectiveness of MGA protocol, it should be considered as a promising alternative in deer ESP since this protocol has less stressful effect on the animal during reproductive management when compared to other ESP.
Electrocardiogram Characteristics of Different Motor Types of Parkinson’s Disease

Aim This study aims to investigate the electrocardiogram characteristics of the different motor types of Parkinson’s disease. Methods The data on 118 patients with Parkinson’s disease (PD), who were initially diagnosed in the Outpatient and Inpatient Department, was collected. Among these 118 PD patients, 74 patients were assigned to the PIGD group, while 44 patients were assigned to the TD group, and their clinical features were analyzed, which included age, course, disease classification, and electrocardiogram parameters (PR, QRS, QT interval, and QTC). Results The QT interval in PD patients was positively correlated with the course of the disease and Hoehn–Yahr stage, and the QT interval in the PIGD group was longer than that in the TD group. Conclusion A prolonged QT interval may indicate a longer disease period and a more severe disease condition.
Nα-1, 3-Benzenedicarbonyl-Bis-(Amino Acid) and Dipeptide Candidates: Synthesis, Cytotoxic, Antimicrobial and Molecular Docking Investigation

Purpose The objective of our work was to prepare a potent and safe antimicrobial and anticancer agents, through synthesis of several peptides and examine their biological activities, namely as, cytotoxically potent and antimicrobial and antifungal agents. Introduction Multidrug-resistant microbial strains have arisen against all antibiotics in clinical use. Infections caused by these bacteria threaten global public health and are associated with high mortality rates. Methods The main backbone structure for the novel synthesized linear peptide is Nα-1, 3-benzenedicarbonyl-bis-(Amino acids)-X, (3–11). A computational docking study against DNA gyrase was performed to formulate a mode of action of the small compounds as antimicrobial agents. Results The peptide-bearing methionine-ester (4) exhibited potent antimicrobial activity compared to the other synthesized compounds, while, peptide (8), which had methionine-hydrazide fragment was the most potent as antifungal agent against Aspergillus niger with 100% inhibition percent. Compounds (6 and 7) showed the highest potency against breast human tumor cell line “MCF-7” with 95.1% and 79.8% of cell inhibition, respectively. The nine compounds possessed weak to moderate antiproliferative effect over colon tumor cell line. The docking results suggest good fitting through different hydrogen bond interactions with the protein residues. In silico ADMET study also evaluated and suggested that these compounds had promising oral bioavailability features. Conclusion The tested compounds need further modification to have significant antimicrobial and antitumor efficacy compared to the reference drugs.
Kaempferia parviflora Extract Alleviated Rat Arthritis, Exerted Chondroprotective Properties In Vitro, and Reduced Expression of Genes Associated with Inflammatory Arthritis

Kaempferia parviflora Wall. ex Baker (KP) has been reported to attenuate cartilage destruction in rat model of osteoarthritis. Previously, we demonstrated that KP rhizome extract and its active components effectively suppressed mechanisms associated with RA in SW982 cells. Here, we further evaluated the anti-arthritis potential of KP extract by using multi-level models, including a complete Freund’s adjuvant-induced arthritis and a cartilage explant culture model, and to investigate the effects of KP extract and its major components on related gene expressions and underlying mechanisms within cells. In arthritis rats, the KP extract reduced arthritis indexes, with no significant changes in biological parameters. In the cartilage explant model, the KP extract exerted chondroprotective potential by suppressing sulfated glycosaminoglycans release while preserving high accumulation of proteoglycans. In human chondrocyte cell line, a mixture of the major components equal to their amounts in KP extract showed strong suppression the expression of genes-associated inflammatory joint disease similar to that of the extract. Additionally, KP extract significantly suppressed NF-κB and MAPK signaling pathways. The suppressing expression of necroptosis genes and promoted anti-apoptosis were also found. Collectively, these results provided supportive evidence of the anti-arthritis properties of KP extract, which are associated with its three major components.
Colony aging affects the reproductive performance of Swiss Webster females used as recipients for embryo transfer

Abstract The objective was to evaluate the influence of colony aging in a Swiss Webster (SW) outbred stock used as recipients for embryo transfer. In the first study, a retrospective analysis was performed throughout several generations during a 38-month period in 2,398 embryos transferred to 108 SW recipients. A decrease in the percentage of live pups from transferred embryos was found at the end of the period. Impairment occurred due to the incidence of maternal cannibalism that increased from 0% to 67-100% (P<0.05), while pregnancy rate (pregnant/transferred recipients) and number of pups per delivered female were not affected throughout the period (P=NS). A following study was carried out to compare the reproductive performance of SW stock vs. B6D2F1 hybrid females in a 5-year interval. The study was conducted on a total of 893 embryos transferred to 40 females (20 SW and 20 B6D2F1) in Year #1, and 514 embryos transferred to 30 females (15 SW and 15 B6D2F1) in Year #5. No cases of maternal cannibalism were found on Year #1 in any of the strains (0/10 and 0/10). However, an incidence of 44,4% (4/9) was seen on Year #5 for SW, while for B6D2F1 the incidence was 0% (0/12) (P<0.05). Further examination of the uterus showed endometrial cysts and abnormal implantation sites in SW on Year #5 but not in B6D2F1 females. In conclusion, this study reports an impairment of the reproductive performance of an early aged SW outbred stock colony mainly due to the occurrence of maternal cannibalism. This finding has important implications for embryo transfer programs conducted in mouse facilities.
Preventive Practices of Ophthalmologists During COVID-19 Pandemic

Purpose To explore ophthalmologists’ preventive practices, and their perceived seriousness and perceived risk of transmission of coronavirus disease 2019 (COVID-19). Methods In a cross-sectional study, a semi-structured questionnaire was distributed online among ophthalmologists. Questions about COVID-19 infection, perceived seriousness, perceived risk of transmission, and recommended COVID-19 preventive practices were asked. Based on the adoption of a preventive measure and its frequency, a maximum preventive score of 25 was computed. Results Among 126 respondents, the mean±SD age was 45.3±10.9 years, and 57.9% worked in a tertiary care hospital. Regarding preventive practices, 96.8% of ophthalmologists wore face masks, 89.6% avoided talking during the slit lamp examination, and 72.2% wore gloves during the ophthalmic examination. Availability of plastic barriers and regular disinfection of slit lamps were reported by 78.6% and 43.7% of ophthalmologists, respectively. The mean preventive score increased with increasing age (p=0.001), and was higher for males (18.96±4.60) compared to females (17.81±4.96). The mean score for perceived severity was higher (p<0.0001) among ophthalmologists with more than 10 years of experience (8.76±1.58) than those with experience of 10 years or less (7.49±1.86). Out of 29 ophthalmologists who had been tested for COVID-19, 11 were found to be positive, giving an overall incidence of COVID-19 infection of 8.7%. Conclusion The ophthalmologists were generally compliant with recommended preventive measures. Some preventive measures, such as the wearing of gloves and regular disinfection of slit lamps, need improvement. We recommend creating awareness of and monitoring for COVID-19 infection control measures in healthcare settings.
Bioinformatics analysis of biomarkers of aristolochic acid-induced early nephrotoxicity in embryonic stem cells

The present study aimed to identify key genes as potential biomarkers for early nephrotoxicity induced by aristolochic acid (AA) in embryonic stem cells (ESCs). An MTT assay was performed to determine the cytotoxicity of AA in ESCs. Differentially expressed genes (DEGs) were identified using the DNA-Chip Analyzer following microarray analysis. Gene Ontology analysis was performed to determine functional terms enriched by the DEGs in the categories biological process, cellular component and molecular function. Furthermore, the DEGs were subjected to Kyoto Encyclopedia of Genes and Genomes analysis to determine pathways they were accumulated in. Furthermore, a protein-protein interaction network was constructed using Cytoscape 3.2 software. Tumor protein 53 apoptosis effector (Perp), cation transport regulator-like 1 (Chac1), adrenoceptor β2 and Wnt6 were selected for confirmation by reverse transcription-quantitative (RT-q) PCR analysis. A total of 72 DEGs (49 upregulated and 23 downregulated) were identified. The DEGs were enriched in functional terms and pathways associated with nephrotoxicity and participated in 92 pathways. A total of two hub genes, fructose-1,6-bisphosphatase (Fbp)1 and Fbp2, were filtered out from the interaction network. Perp and phorbol-12-myristate-13-acetate-induced protein 1 were demonstrated to have vital roles in the p53 signaling pathway which was indicated in the interaction network. The results of the RT-qPCR analysis were consistent with the microarray data. Taken together, the present study suggested that hub genes involved in the p53 pathway, including Fbp1, Fbp2 and Perp, may serve as potential biomarkers for early nephrotoxicity induced by AA.
Efficacy and Safety of a Decision Support Intervention for Basal Insulin Self-Titration Assisted by the Nurse in Outpatients with T2DM: A Randomized Controlled Trial

Objective The main aim of this study was to evaluate a combined fasting blood glucose based dosage self-titration setting and decision supported telephone coaching intervention on glycemic control and diabetes self-management skills, compared to the conventional care. Methods A 12-week, single-blinded, randomized controlled trial was conducted on adults with type 2 diabetes (T2DM) primarily treated with basal insulin. After randomization, the intervention group (IG, n = 426) received a basal insulin self-titration decision support intervention administered by the Diabetes Specialty Nurses while the control group (CG, n = 423) received conventional care for 12 weeks, both included five telephone interviews. The primary efficacy endpoint was the effect of intervention on glycemic control, measured as the change in glycated hemoglobin (HbA1c) from baseline to Week 12 (after intervention) compared to the control group. Other endpoints included comparisons of the effects of intervention on fasting plasma glucose (FPG), postprandial plasma glucose (PPG), body weight, Michigan diabetes knowledge test (MDKT), diabetes empowerment scale-short Form (DES-DSF), and summary of diabetes self-care activities (SDSCA). Changes in the primary and secondary outcomes were compared using the t-test for continuous variables with a normal distribution and χ2-test for categorical variables. Results The IG showed more improvements on mean HbA1c, compared to the CG (−2.8% vs −1.8%), so did the FPG, PPG, MDKT, DES-DSF and SDSCA (all P<0.01) after the 12-week follow up. Though the final mean insulin dose in the IG was higher than the CG at the end of the study (0.32 U/kg vs 0.28 U/kg), the changes of body weight were similar between the two groups (0.46kg vs 0.40kg, P=0.246), and the proportion of patients with hypoglycemia events during the whole trial were similar (20.65% vs 17.73%, P=0.279). Conclusion Decision supporting of basal insulin glargine self-titration assisted by Diabetes Specialty Nurses is effective and safe in patients with T2DM. Decision supported telephone coaching intervention offers ongoing encouragement, guidance, and determination of relevant sources of decisional conflict, facilitating adjusting the insulin dose.
