An Enhanced Packet Transmission Framework for Handling Real Time Burst Traffic in Wireless Sensor Networks
Authors: Ganesan Sangeetha , Muthuswamy Vijayalakshmi 
Published: January 2022

Abstract
Congestion control for real time traffic is an important network measure to be handled in case of repeated event triggers, continuous packet re-transmissions, node interference, node deaths and node failures in Wireless Sensor Networks (WSNs). Network modelling for transmission of packets from source node to sink using probabilistic M/Pareto and Poisson processes have been examined in the past. The existing methodologies are deficit in designing a queuing framework considering other network parameters such as energy consumption and delay for alleviating congestion and thereby efficiently routing packets to sink by reducing packet drops. To overcome this fall back, a Minimum Weight Estimation for Mitigating Congestion during Real Time Burst Traffic (MWCBT) framework is proposed. This gives a precautionary solution against heavy traffic occupancy among the interim and sink-neighbouring nodes in WSNs is proposed. Routing of packets using a congestion-free path is required to increase the node lifespan. An optimal M/Pareto stochastic traffic generator is used in combination with traffic factors such as energy and delay to predict amount of traffic across nodes. A simpler congestion prediction mechanism is performed to control the occurrence of heavy-tailed traffic distributions. A torrent weight value for incoming traffic is generated at each node periodically that directs routing of data packets to sink. The devised MWCBT framework supervises real-time traffic congestion and is found to be more optimal than the existing approaches for network traffic modelling. The proposed approach achieves greater packet delivery ratio and less node congestion compared to the existing network modelling techniques.

Authors: Shao Yabin , Wang Ning , Gong Zengtai 
Published: January 2022

Abstract
The confidence levels can reduce the influence of the unreasonable evaluation value was given by the decision maker on the decision-making results. The Archimedean t-norm and t-conorm (ATS) also have many advantages for the processing of uncertain data. Under this environment, the confidence q-rung orthopair fuzzy aggregation operators based on ATS is one of the most successful extensions of confidence q-rung orthopair fuzzy numbers (Cq-ROFNs) in which decrease the deviation caused by the subjective perspective of the decision maker in the multicriteria group decision-making (MCGDM) problems. In this paper, we propose weighted, ordered weighted averaging aggregation operators and weighted, ordered weighted geometric aggregation operators based on ATS, respectively. Moreover, the properties and four specific forms associated with aggregation operators are also investigated. In this study, a novel MCGDM approach is introduced by using the proposed operator. A reasonable example is proposed and compared the results which are obtained by our operators and that in existing literature, so as to verify the rationality and flexible of our method. From the study, we concluded that the proposed method can reduce the impact of extreme data, and makes decision-making results more reasonable by considering the attitudes of decision-makers.

Abstract
Dirty air and poor access to healthcare threatens the lives of billions of people in low-income regions of the world. We investigated whether upper-airway hydration might alter two-phase flow in the airways on normal tidal breathing and be a useful, safe, easily distributed non-drug intervention for limiting risks of COVID-19. In observational human volunteer studies involving 464 human subjects in Marburg, Germany (357 normal subjects), Boston, US (20 healthy subjects), and Bangalore, India (87 subjects recently tested positive for COVID-19), we find that respiratory droplet generation increases by up to 4 orders of magnitude with up to 1% total body mass dehydration (n=20), and in dehydration-associated states of advanced age (n=357), elevated BMI-age (n=148), and SARS-CoV-2 infection (n=87). Hydration of the nose, larynx and trachea in a protocol of exercise-induced dehydration by the nasal inhalation of calcium-rich hypertonic salt droplets of mean diameter 8-12 µm diminished respiratory droplet numbers and increased oxygenation relative to a non-treatment control (P<0.05). In a randomized double-blinded nasal-saline control study, thrice-a-day delivery of the calcium-rich hypertonic salts (active) over three days suppressed respiratory droplet generation by 51% +/- 11% and increased oxygen saturation by 48.08% ± 9.61% (P<0.001) in COVID-19 positive subjects (n=20), while no changes in exhaled aerosol (P=0.235) or oxygen saturation (P=0.533) were observed in the nasal-saline control group (n=20). In the active group 47% of patients discharged with no self-reported symptoms while all of the subjects in the nasal saline group discharged with lingering symptoms. Hydration of the upper airways appears promising as a non-drug approach for reducing risks of lower respiratory-tract infections such as COVID-19.

Published: January 2022

Abstract
Background
Effective prevention of healthcare-associated infections (HAIs) requires early identification of at-risk patients. There is no score designed to predict HAIs. The present study was aimed to explore an available score, Systemic inflammatory syndrome (SIRS) score, on admission in predicting HAIs among critically ill patients.
Methods
This study was based on the Medical Information Mart for Intensive Care III (MIMIC III) version 1.4. Patients with HAIs were matched with control patients who had no HAIs in a 1:1 ratio based on age, gender, mechanical ventilation, deep venous catheterization, urethral catheterization, and surgical operation. Subgroup analyses were conducted according to various variables including infection likelihood on admission. The prognostic values of SIRS and infectious SIRS on admission in predicting HAIs were analyzed using logistic regression.
Results
A total of 2437 patients with HAIs and 2437 matched controls were enrolled in the final analysis. Adjusted odds ratio (ORs) (95% confidence interval [CI]) for HAIs of SIRS scores (1 to 4) on admission was 1.48 (0.77-2.83), 1.86 (0.99-3.47), 2.14 (1.15-3.98), and 2.58 (1.39-4.80). Adjusted ORs (95%CI) for HAIs of SIRS (score≥2) and infectious SIRS were 1.57 (1.27-1.94) and 1.78 (1.52-2.09), respectively. Subgroup analyses showed that SIRS on admission was an independent risk factor for HAIs in patients admitted without definite and probable infection likelihood (OR=1.54, 95%CI 1.28-1.93). However, it was not a risk factor for HAIs inpatients admitted with infection, in non-white patients, and in patients with liver disease or obesity, and in patients who received total parenteral nutrition (TPN) (all P>0.05). In addition, it was showed that infectious SIRS on admission was not a risk factor for HAIs in black patients and in patients with obesity, and those received TPN (all P>0.05).
Conclusions
Infectious SIRS on admission significantly predicts HAIs among critical illness patients. SIRS on admission was a predictor of HAIs in ICU patients admitted without infection but not in patients admitted with infection.

Published: January 2022

Abstract
Background
vitamin D deficiency is associated with respiratory problems in neonates. The late preterm or near-term neonates who have been admitted for tachypnea and fully recovered before 12 h, we called Non-specific respiratory distress syndrome (NRDS). The present study aimed to evaluate the effect of 25(OH) D administration in pregnant women at risk of preterm delivery on the incidence of NRDS in their infants.
Methods
This single-blind clinical trial was performed on mothers and neonates with a gestational age of 32-37 weeks who were referred with labor pains from February 20th 2021 to June29th 2021 in the obstetrics and gynecology department and intensive treatment unit of Ghaem Hospital, Mashhad University of Medical Sciences, Iran. Within 72 h of preterm delivery, a single dose of 50,000 units of intramuscular 25-hydroxy vitamin D was injected into pregnant women in the intervention group. Also a sample containing 1.5 ml of whole blood was taken from the umbilical cord of the infant and mother to assess the level of vitamin D.
Results
In the present study, there was a significant relationship between the two groups of control and intervention in terms of weight (P=001), first (P=0.027) and fifth minute Apgar score (P=0.001) in infant, incidence of NRDS (P=0.001) and maternal age (P=0.004). The results showed no statistically significant difference between the two groups in terms of gender (p = 0.673), type of delivery (p = 0.299), level of vitamin D of the mothers (P=0.053) and infants (P=0.805).
Conclusions
The single injection of vitamin D into the mother prone to preterm birth over 31 weeks of gestation reduces transient respiratory problems in these infants.

Abstract
This study aimed to have a full understanding of the steroidogenic acute regulatory gene family member and evolutionary relationship in grape. 23 VvSTARD gene members were identified and divided into five groups in different species. Analyses of the gene codon preference, selective pressure, and tandem duplication of the VvSTARD, AtSTARD, and OsSTARD genes indicated that synteny relationship occurred in grapes, Arabidopsis thaliana, and rice genomes. The 8 lipid transporter proteins were found in the tertiary structure of the STARD gene family in grape. Expression profiles of the three species microarrays showed that the expression levels of the STARD genes in different organs and the response to abiotic stress in the same subgroup had similar characteristics. In addition, analysis of the VvSTARD genes expression levels was detected in response to different hormones and abiotic stresses by quantitative real-time polymerase chain reaction (qRT-PCR), and the results were the same as those predicted by the cis-elements and the expression profiles. Meanwhile, VvSTARD5 gene was screened in high concentration NaCl treatment by qRT-PCR. Furthermore, the VvSTARD5 was located at the nucleus by subcellular location. Through the function analysis of salt tolerance in transgenic tomato, overexpression VvSTARD5 obviously improved tolerance to salt stress. Taken together, our findings Preliminary identify the functions of VvSTARD gene family and vertify STARD5 that be likely involved in regulating salt tolerance, which may have potential application molecular breeding in grape.

Abstract
The use of personal protective equipment (PPE) is compulsory when accessing public places due to the ongoing COVID-19 pandemic in many countries. Facemasks are the most common PPE used, however, some people use face shields and gloves. Frequent hand sanitizing is also recommended aiming to control the spread of the disease. All these activities generate a large amount of plastic waste daily. In Sri Lanka, it is estimated that 12 million facemasks are used daily, while 0.22 million gloves and 0.29 million face shields are used. Out of 12 million facemasks, 10 million are surgical or N95 masks. In addition, 0.79 million sanitizer bottles are used in a day, leaving empty plastic bottles. The most common method of disposing of facemasks in Sri Lanka is open burning by the users at their homes (55%). The rate of burning is comparatively low for other PPE. Although nearly 30% of people handover used facemasks to the municipal solid waste collection, there are no special precautions taken for separate collection and safe disposal. Guidelines are in place for handling healthcare waste generated in households under self-quarantine, but they are not applied for PPE waste generated in other households. Major drawbacks in PPE waste management is identified and mitigation measures were proposed. The estimate of waste plastics generated due to PPE use is 88.5 tonnes per day in the country. Energy recovery via pyrolysis may be a viable alternative to landfilling and affordable for developing countries.

Published: January 2022

Abstract
This paper combines the advantages of both VLC communication and RF communication for car-to-car applications to achieve a higher data rate, more range coverage, smaller delay, and smaller BER. In the proposed scheme, the VLC maximum communication distance is chosen as 100 m per-hop approximately, which can be extended through multi-hop up to the timeout window of 5 hops. In contrast, the RF maximum communication distance is chosen as 200 m per-hop approximately, which is reasonable at the frequency band of 70 GHz to 90 GHz due to the high attenuation at this frequency band. A MATLAB simulation for a car-to-car framework is built to demonstrate and compare the BER, throughput, and delay outcomes at a hybrid VLC and RF communication. Our results show that VLC can achieve up to four times of the RF throughput while maintaining low BER of 10-6 and small delay of 10-4 with respect to RF communication only.

Published: January 2022

Abstract
A regulated cascode current mirror (RGC) and its improved version with bulk driven quasi floating gate technique (BD-QFG) are presented in this paper. The proposed BD-QFG RGC current mirror (CM) is compared with the conventional (GD) RGC CM to show the performance improvement. The conventional and unconventional CM are implemented in Candace Virtuoso using 90 nm CMOS technology. For input current (Iin) varied from 0 to 200 μA and for 0.8 V supply voltage, the simulation results present that the proposed BD-QFG RGC CM has less variation in current transfer error (0.2%) as compared to the GD RGC CM (12%). The output voltage requirement for 200 µA input current is respectively 0.7 V and 0.17 V for the GD RGC CM and the BD-QFG RGC CM. The power consumption of the proposed circuit is 22.71 μW which is 0.15 μW higher than the GD RGC (22.56 μW). The total harmonic distortion (THD) of the proposed circuit is 0.4% which is 1.1% less than the conventional circuit (1.5%). All these improvements in the proposed BD-QFG RGC CM are attained at a cost of 0.05 GHz reduction in frequency (2.31 GHz). The minimum supply voltage of BD-QFG RGC CM and GD RGC CM is 0.4 V and

Abstract
Aniline is a kind of refractory contaminant that is difficult to be degraded by microorganisms. Ozone is a green and efficient reagent to oxidize aniline, while the ozone oxidation efficiency is restricted by the low ozone mass transfer rate. Micro-nano bubble ozonation has been developed as a new method to significantly improve the ozone utilization rate, while the characteristics of ozone micro-nano bubble when compared with dissolved ozone is not clear. The paper carried out batch experiments to research the oxidation effect of aniline by ozone water (OW) and ozone micro-nano bubble water (OMNBW), and found that the degradation rate of aniline by OMNBW was 2.8~5.9% higher than that by OW. The increase of pH had a negative effect on the degradation of aniline by OW and OMNBW. SO42-, Cl-, HCO­3- and Mg2+ could inhibit the degradation efficiency by 0.04%, 0.99%, 0.44% and 10.4% for OW, while the ratios were 1.1%, 6.4%, 4.1% and 1.5% for OMNBW. The addition of humic acid and fulvic acid could decrease the oxidation rate of aniline by 35% and 49% for OW, while the ratios were 41% and 62% for OMNBW. Through quenching experiment, it was found that the direct oxidation by ozone molecules and the indirect oxidation by superoxide radicals were main pathways for aniline oxidation by OW and OMNBW. This work provided a practical guide for the application of OMNBW in wastewater and groundwater treatment process.

Abstract
Purpose: Oxidative stress is known to be a decisive factor in the wide etiopathogenesis of optic neuropathy. This study aimed to comprehensively evaluate the interaction of optic neuropathy’s clinical course with systemic oxidative damage and antioxidant response dynamics in a large series.Methods: This case-controlled clinical study included 33 non-arteritic anterior ischemic optic neuropathy patients and 32 healthy individuals. Extensive systemic oxidation profiles were statistically compared between the two groups, and correlations between the clinical and biochemical data in the patient group were analyzed.Results: Vitamin E and MDA levels were significantly higher in the patient group. Significant correlations were observed in the analyses between clinical findings and oxidative stress parameters. Correlations between vitamin E and intraocular pressure, between B12 and cup-to-disc ratio, between antioxidant glutathione and SOD enzyme systems, and between uric acid and age were found to be very significant. As significant correlations were found in either clinical and biochemical data or in oxidative stress parameters, correlations between vitamin E and cholesterol, MDA was found to be very significant. Conclusions: This study not only supplies significant information regarding oxidative damage and antioxidant response in NAION, but also points out the specific interactions of neuromodulators, like vitamin E, in intracellular signaling pathways and regulation mechanisms. A better reading of these connections may help improve diagnosis, follow-ups and treatment criteria and strategies.

Published: January 2022

Abstract
Background The reported incidence of juvenile idiopathic arthritis (JIA) varies from studies around the world, depending on patient collection techniques, geographic region, and time. Our aim was to study the mean annual incidence of juvenile arthritis in a population-based setting using two regional cohorts of children diagnosed with juvenile chronic arthritis (JCA) and JIA over a period of 31 years.Findings The study population was 651 children diagnosed 1980-2010. The mean annual incidence over the period was 9.9 per 100,000 children, with a range from 4.2 per 100,000 in 1980 to 17.1 per 100,000 children in 2010. When comparing incidence rate between the decade of diagnosis using rate ratios, there is a significant difference with diagnosis 1980-1989 as comparator.Conclusions We show a statistically significant increase in the incidence of JIA over three decades in a population-based cohort of children with juvenile arthritis.

Abstract
The estuarine ecosystem of Laguna Madre de Dios (LMD), in the Caribbean coast of Costa Rica, is exposed to contamination with pesticide residues coming from the upstream agricultural areas. Biomarkers can provide a better indication of the fitness of biota in real mixture exposure scenarios than traditional lethal dose toxicity measurements. Here, we measured biomarkers of biotransformation, oxidative stress and neurotoxicity on Astyanax aeneus, an abundant fish species in LMD. Glutathione S-transferase activity (GST), catalase activity (CAT), lipid peroxidation (LPO), and cholinesterase activity (ChE) were measured in fish collected during seven sampling campaigns, carried out between 2016 and 2018. Pesticide residues were analysed in surface water samples collected every time fish were sampled. Residues of 25 pesticides, including fungicides, insecticides and herbicides, were detected. The biomarkers measured in A. aeneus varied along the sampling moments, however, biotransformation and oxidative stress signals showed coupled responses throughout the assessment. Furthermore, significant correlations were established between three biomarkers (GST, LPO and CAT) and individual pesticides, as well as between GST and LPO with groups of pesticides with shared biocide action. Among pesticides, insecticide residues had a major influence on the responses observed in fish. This work shows that the frequent exposure to environmentally relevant concentrations of pesticides can be related to physiological responses in fish that affect their health. This early warning information should be considered to improve the protection of estuarine ecosystems in the tropics.
