Published: January 2022

Demand for the high-precision and high-efficiency machining of hard ceramics, such as silicon carbide for semiconductors and hardened steel for molding dies, has significantly increased for optical and medical devices as well as for powered devices in automobiles. Certain types of hard metals can be machined by deterministic precision-cutting processes. However, hard and brittle ceramics, hardened steel for molds, and semiconductor materials have to be machined using precision abrasive technologies, such as grinding, polishing, and ultrasonic vibration technologies that use diamond super abrasives. The machining of high-precision components and their molds/dies using abrasive processes is very difficult due to their complex and nondeterministic natures as well as their complex textured surfaces. Furthermore, the development of new cutting-edge tools or machining methods and the active use of physicochemical phenomena are key to the development of high-precision and high-efficiency machining.
This special issue features 11 research papers on the most recent advances in precision abrasive technologies. These papers cover the following topics:
- Characteristics of abrasive grains in creep-feed grinding
- Quantitative evaluation of the surface profiles of grinding wheels
- ELID grinding using elastic wheels
- Nano-topographies of ground surfaces
- Novel grinding wheels
- Grinding characteristics of turbine blade materials
- Polishing mechanisms
- Polishing technologies using magnetic fluid slurries
- Application of ultrasonic vibration machining
- Turning and rotary cutting technologies
This issue is expected to help its readers to understand recent developments in abrasive technologies and to lead to further research.
We deeply appreciate the careful work of all the authors, and we thank the reviewers for their incisive efforts.

Abstract
Background：Gastric cancer (GC) is one of the most principle malignant cancers in the digestive system. Moreover, the critical role of circular RNAs (circRNAs) has been identified in GC development. Methods：In this context, the purpose of research was to explore the regulatory mechanism circ_0001013, a novel circRNAs predicted by our research, in GC. The differential circRNAs and related mechanism in GC were predicted by microarray analysis. Circ_0001013, miR-136, and TWSG1 expression in GC clinical samples and cells was detected by RT-qPCR. The relationship among circ_0001013, miR-136, and TWSG was assessed by dual-luciferase reporter assay, biotin coupled probe pull-down assay, and biotin coupled miRNA capture. After gain- and loss-of-function assays in GC cells, cell proliferation, migration, invasion, and cell cycle and apoptosis were measured by EdU assay, scratch test, Transwell assay, and flow cytometry respectively. The effect of circ_0001013 on tumor growth was detected by xenograft tumor in nude mice. Results ：Microarray analysis predicted a novel circRNA, circ_0001013, was upregulated in GC, which was confirmed by RT-qPCR detection in GC tissues and cells. Besides, miR-136 was downregulated but TWSG1 was highly expressed in GC tissues. Mechanically, circ_0001013 could bind to miR-136, and miR-136 negatively targeted TWSG1 in GC cells. Silencing circ_0001013 or TWSG1 or overexpressing miR-136 decreased GC cell proliferation, migration, invasion, and cell cycle arrest and accelerated cell apoptosis. Circ_0001013 silencing decreased TWSG1 expression and inhibited transplanted tumor growth in nude mice. Conclusion：Circ_0001013 elevated TWSG1 expression by binding to miR-136, thereby exerting oncogenic effect in GC.

Abstract
In the Qinghai-Tibet Plateau, both the large daily temperature difference and soil salinization make plants susceptible to abiotic stresses such as freeze-thaw and salinity. Meanwhile, crops in this area could be subjected to the influence of artemisinin, an allelochemical exuded by Artemisia annua. In the context of freeze-thaw and salinity stresses, artemisinin was induced as an allelopathy stress factor to explore the physiological response of highland barley, including the relative electrical conductivity (RC), soluble protein (SP) content, malondialdehyde (MDA) content, antioxidant enzyme activity, and water use efficiency (WUE).There data suggested that artemisinin weakened the self-osmotic adjustment ability of seedlings, reducing the SOD activity in scavenging efficiency of reactive oxygen species, then causing oxidative damage to cell membrane of seedlings, which significantly increases the content of RC and MDA. Artemisinin stress can reduce the WUE of seedlings and weaken the photosynthesis intensity of seedlings as well. In a word, salinity stress and artemisinin respectively showed a synergistic compound relationship with freeze-thaw stress,

Abstract
Preterm infants have a low level of bone mineralization compared to those born at term. The purpose of the present study was to investigate the effect of reflex locomotion therapy (RLT) on bone mineralization and growth in preterm infants and compare its effect against other physiotherapy procedures. 46 preterm infants born at 29-34 weeks were randomized to three groups: One group received RLT (n=17); other group received passive movements with gentle joint compression (n=14); and control group received massage (n=15). All treatments were carried out at the neonatal unit lasting one month. The main outcome measure was the bone mineralization measured with Tibial Speed of Sound (Tibial-SOS). All groups were similar in terms of gestational age (31.8±1.18), birth weight (1,583.41±311.9), and Tibia-SOS (1,604.7±27.9), at the beginning of the intervention. At the end of the study, significant differences were found among groups in Tibial-SOS [F(4,86)=2.77, p=0.049, ηp2 = 0.114] in benefit of RLT group. In conclusion, RLT has been effective in the improvement of Tibial-SOS, and has been more effective than other physical therapy modalities; therefore it could be considered as one of the most effective physiotherapeutic modalities for the prevention and treatment of osteopenia of prematurity.

Abstract
Introduction India is one of the leading producers and consumer of tobacco. Additionally, India has one of the highest global prevalence of oral leukoplakia (OL). However, large epidemiological studies from Madhya Pradesh (Central India), the state with maximum consumers of tobacco products in India, are lacking. Objective Thus, we assessed the prevalence of OL among individuals residing in Central India and evaluated its association with age, gender, and history of adverse habits. Methods This was a prospective, cross-sectional study involving 9954 patients visiting the out-patient Department of Oral Medicine and Radiology over a period of 15 months (January 2019 to March 2020). The clinical diagnosis of OL was arrived by exclusion of all the lesions mimicking OL. Univariate and multivariate analyses were performed to assess the association between OL and age, sex, and history of adverse habits. Results The prevalence of OL was 5.6% (557/9954). It was predominant in males (male-to-female ratio=3.9:1) and increased with advancing age. The odds of developing OL was higher among patients aged ≥50 years (OR=1.08; 95%CI: 1.07–1.08, p-value<0.0001), those with history of smoking tobacco (OR=1.32; 95%CI: 1.05–1.68, p-value=0.02), consuming smokeless tobacco (OR=318.60; 95%CI: 101.68–998.30, p-value<0.0001), and alcohol (OR=1.15; 95%CI: 9.0–1.49, p-value=0.269). Females had lower odds of developing OL (OR=0.77; 95%CI: 0.60–0.99, p-value=0.042). Conclusion We observed high prevalence of OL (5.6%). OL was significantly associated with older age, male sex, and tobacco-related adverse habits. While, alcohol consumption may possibly be a risk factor, no statistically significant relation was observed.

Abstract
A SAC-OCDMA-OFDM-DWDM system using a flat optical frequency comb generator and a coherent communication system is proposed in this research. The objective is to develop a novel OCDMA communication system that is appropriate and dedicated to multiservice networks. A comparison between the two codes, EDW and RD, has been presented. It has been concluded that the RD code system has better performance in terms of robustness and number of users than the EDW code. By analyzing the BER for several symbol rates and comparing it to the pre-FEC threshold, the proposed system demonstrates its effectiveness against linear and nonlinear effects. Performance evaluation of the proposed system is carried out via co-simulation of OptiSystem and MATLAB.

Abstract
Endophytic fungi are the main source of natural compounds including pigments having various industrial applications. Present study describes the production of extracellular orange-brown pigment from an endophytic fungal isolate Aspergillus sp. N11from Teucrium stocksianum. The optimum conditions for pigment production from this isolate was investigated and results showed that highest yield was observed in Potato dextrose broth, at pH 5 and 30 ℃ under shaking condition at 150 rpm for 7-10 days. The pigment was extracted in ethyl acetate and purified using column chromatography. Three different pigments were purified (yellow, light brown and orange-brown) and characterized based on Thin layer chromatography and Fourier transform infrared spectroscopy. The antimicrobial activity of purified fragments showed maximum zone of inhibition of 40 mm against S. aureus while for P. aeruginosa maximum zone of 50 mm and maximum antifungal activity of 20 mm against C. albicans. The antioxidant potential of purified pigment obtained from Aspergillus sp. N11 indicates that maximum scavenging activity of 67%. The results showed that purified pigments are astaxanthins belonging to oxygen containing carotenoids. The purified astaxanthins showed antibacterial, antifungal and antioxidant activities indicating its potential to be utilized in pharmaceutical and food industries.

Published: January 2022

Abstract
This work investigates the applicability of thermally treated calcium-rich clay minerals (CRCMs), such as sepiolite (SPL), attapulgite (ATT), and dolomite (DLM) to hinder the nitrogen (N) and phosphorus (P) release from river sediments. A non-woven fabric mat (NWFM) or a sand layer were also capped as armor layers, i.e., placed over CRCMs to investigate the capping impact on the N/P release. The capping efficiency was evaluated in a cylindrical reactor, consisting of CRCMs, armor layers, sediments, and sampled water. We monitored N/P concentrations, dissolved oxygen (DO), oxidation reduction potential, pH, and electric conductivity in overlying water over 70 days. The DO concentrations in the uncapped and capped conditions were preserved for 30 days and 70 days (until the end of experiment duration), respectively. ATT showed higher efficiency for NH4-N and T-N than the other two materials, and the capping efficiency of NH4-N was measured as 96.4%, 93.7%, and 61.6% when capped with 2 cm sand layer, 1 cm sand layer, and NWFM layer, respectively. DLM showed a superior rejection capability of PO4-P to ATT and SPL, reported as 97.2% when capped with 2 cm sand armor. The content of weakly adsorbed-P was lower in the uncapped condition than in the capping condition. It can be concluded that ATT and DLM can be used as capping agents to deactivate N and P, respectively, to reduce water contamination from sediments of the eutrophic river.
Tropical Cyclone Damage Assessment using a Projection Pursuit Dynamic Cluster Model

Published: January 2022

Abstract
Using data from 62 tropical cyclones (TCs) that landed in Guangdong Province in China between 2000 and 2019, we calculated six indices—minimum central pressure, maximum wind speed, maximum rainstorm ratio, cumulative surface rainfall, cyclone track length and lifetime—and constructed a projection pursuit dynamic cluster (PPDC) model to assess TC damage risk. Although a single index may provide correct information on the intensity of certain types of damage, a comprehensive damage risk assessment cannot be obtained from individual indices alone. The PPDC model is a stable tool for TC damage risk assessment, especially in terms of economic loss, agricultural disaster area and disaster-affected population. Model validation improved the correlation of each of the indices. Output from the PPDC model for disaster-affected population and agricultural disaster-affected area also improved after model validation. We examined the limitations of the single indices using data from three TCs. Output from the PPDC model can closely reflect the intensity of the damage caused by the cyclones. Projection pursuit dynamic clustering is a new and objective method for typhoon damage risk assessment, and provides the scientific basis to support disaster prevention and mitigation.
Size Constraint to Limit Interference in DRL-Free Single-Ended Biopotential Measurements
Authors: Catacora Valentin , Guerrero Federico , Spinelli Enrique 
Published: January 2022

Abstract
Purpose: In this work, it is shown that small, battery-powered wireless devices are so robust against electromagnetic interference that single-ended amplifiers can become a viable alternative for biopotential measurements, even without a Driven Right Leg (DRL) circuit. Methods: A power line interference analysis is presented for this case showing that this simple circuitry solution is feasible, and presenting the constraints under which it is so: small-size devices with dimensions less than 40 mm × 20 mm. Results: A functional prototype of a two-electrode wireless acquisition system was implemented using a single-ended amplifier. This allowed validating the power-line interference model with experimental results, including the acquisition of electromyographic (EMG) signals. The prototype, built with a size fulfilling the proposed guidelines, presented power-line interference voltages below 1.2 µVPP when working in an office environment. Conclusion: It can be concluded that a single-ended biopotential amplifier can be used if a sufficiently large isolation impedance is achieved with small-size wireless devices. This approach allows measurements with only two electrodes, a very simple front-end design, and a reduced number of components.
Meaningfulness Buffers and Crisis of Meaning Mediates The Longitudinal Effect of Covid-19 Stress On General Mental Distress
Authors: Schnell Tatjana , Krampe Henning 
Published: January 2022

Abstract
Background: Reactions to the COVID-19 pandemic are diverse. People who experience the situation as stressful (COVID-19 stress) appear vulnerable to developing general mental distress. Moreover, existential crises can arise. The identification of buffering factors and their effect over time is therefore highly relevant. The current study examined longitudinal protective effects of meaningfulness and self-control and negative effects of crisis of meaning on general mental distress. Methods: N=431 participants from Germany and Austria (mean age: 42 years) completed an online survey in both April/May (T1) and July/August 2020 (T2). We examined (i) whether two personal resources, meaningfulness, and self-control, measured at T1, moderated the longitudinal effect of COVID-19 stress (T1) on general mental distress (T2), and (ii) whether crisis of meaning (T1) mediated the latter effect. Results: Meaningfulness and self-control predicted lower symptoms of anxiety and depression over time, and crisis of meaning predicted higher symptoms. Meaningfulness but not self-control buffered the longitudinal effect of COVID-19 stress on general mental distress. COVID-19 stress was associated with crisis of meaning which, in further consequence, predicted general mental distress three months later. Conclusions: Meaningfulness and self-control appear to have generally protective effects on psychological distress. Moreover, meaningfulness seems to be particularly protective when people feel burdened by the situation. Strengthening this resource is thus especially appropriate for vulnerable populations. Measures that support meaningfulness will also prevent the emergence of crises of meaning, which can be triggered by acute stress reactions and appear to affect mental health in the longer term.

Abstract
BackgroundFailure to use antenatal care (ANC) and inadequate receipt of components of ANC pose a significant risk for both the pregnant woman and baby. This study aimed to examine a regional analysis of factors associated with no or inadequate receipt of components of ANC services among Indian women.MethodInformation on 184,628 women of reproductive age 15-49 years from the 2015-16 India National Family Health Survey (NFSH-4) was used. Survey multinomial logistic regression analyses that adjust for cluster and survey weights were conducted to assess the socio-demographic and other factors associated with no or receipt of inadequate receipt of components of ANC in the six regions in India.ResultsAcross regions in India, 18% of women reported no ANC, and the prevalence of inadequate and adequate receipt of components of ANC in all six regions ranged from 16% to 43% and 34% to 81%, respectively. Our analyses revealed that in all six regions, poor households reported increased odds of receiving no or inadequate receipts of components of ANC. In all six regions, inadequate receipts of components of ANC was significantly higher among women who had limited knowledge about pregnancy complications and post-delivery complications. In all the six regions except the East region, women who delivered their babies at home reported higher odds of receiving no or inadequate receipts of components of ANC and women who had no postnatal checkup after delivery reported higher odds of receiving no or inadequate receipts of components of ANC in all regions except South, West and North East regions. Low levels of women's education and women who delivered their babies at home were associated with increased odds of receiving no or inadequate receipts of components of ANC in all six regions except North and East regions.ConclusionA better understanding of the factors associated and incorporating them into the short- and long-term intervention strategies, including free financial support from the Indian government to encourage pregnant women from lower socioeconomic groups to use health services across all regions.
