    Abstract Smart cities and the Internet of Things have enabled the integration of communicating devices for efficient decision-making. Notably, traffic congestion is one major problem faced by daily commuters in urban cities. In developed countries, specialized sensors are deployed to gather traffic information to predict traffic patterns. Any traffic updates are shared with the commuters via the Internet. Such solutions become impracticable when physical infrastructure and Internet connectivity are either non-existent or very limited. In case of developing countries, no roadside units are available and Internet connectivity is still an issue in remote areas. Internet traffic analysis is a thriving field of study due to the myriad ways in which it may be put to practical use. In the intelligent Internet-of-Vehicles (IOVs), traffic congestion can be predicted and identified using cutting-edge technologies. Using tree-based decision-tree, random-forest, extra-tree, and XGBoost machine learning (ML) strategies, this research proposes an intelligent-transport-system for the IOVs-based vehicular network traffic in a smart city set-up. The suggested system uses ensemble learning and averages the selection of crucial features to give high detection accuracy at minimal computational costs, as demonstrated by the simulation results. For IOV-based vehicular network traffic, the tree-based ML approaches with feature-selection (FS) outperformed those without FS. When contrasted to the lowest KNN accuracy of 96.6% and the highest SVM accuracy of 98.01%, the Stacking approach demonstrates superior accuracy as 99.05%.

    Abstract A sustainable biorefining and bioprocessing strategy was developed to produce edible-ulvan films and non-edible polyhydroxybutyrate films. The preparation of edible-ulvan films by crosslinking and plasticisation of ulvan with citric acid and xylitol was investigated using Fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) analysis. The edible ulvan film was tested for its gut-friendliness using Lactobacillus and Bifidobacterium spp. (yoghurt) and was shown to improve these gut-friendly microbiome's growth and simultaneously retarding the activity of pathogens like Escherchia coli and Staphylococcus aureus. Green macroalgal biomass refused after the extraction of ulvan was biologically processed by dark fermentation to produce a maximum of 3.48 (± 0.14) g/L of volatile fatty acids (VFAs). Aerobic processing of these VFAs using Cupriavidus necator cells produced 1.59 (± 0.12) g/L of biomass with 18.2 wt% polyhydroxybutyrate. The present study demonstrated the possibility of producing edible and non-edible packaging films using green macroalgal biomass as the sustainable feedstock.

    Abstract We have realized for the first time the multibreather vector multi-solitons supporting collision dynamics with many interaction effects (namely reflection, attraction, beating, etc., effects) associated with the coupled nonlinear Schrödinger family equations having multiple applications. Such effects can be suppressed or enhanced by using the soliton parameters. Here each colliding multibreather vector one-soliton is composed with many soliton and antisoliton parts. Our solutions have freedom to control the number of soliton and antisoliton parts used to compose a vector one-soliton with a definite breathing length. It is also interesting to observe that the breathing maps associated with the obtained solutions depend on their free parameters and also the system parameters. All such investigations help us to realize different breathing mechanisms (namely pedaling, toggling, symmetric compression, symmetric elongation, asymmetric compression, asymmetric elongation, etc.) supported by the colliding one-solitons. An existing breathing mechanism of a given vector breather one-soliton can be suppressed or switched into another mechanism by tuning certain parameters appropriately. Because of such features we believe that this kind of study will further give impetus on the Lindner-Fedyanin system in the continuum limit, and find the potential applications in fiber coupler and also in Bose-Einstein condensates.

    Abstract Five Indian wheat cultivars and their hybrid with MACS 2496 were selected for the present study. They were screened for seed storage proteins Secalin by the SDS-PAGE under non-reducing conditions for the presences of sec-1 which is a characteristic feature of 1BL/1RS translocation. Total soluble proteins were also estimated in all the varieties by the Lowry’s method. Results revealed that all the hybrids possess the sec-1 band denoting the 1BL/1RS translocation and conferring the transfer of gene complex Sr31 + Lr26 + Yr9. This study reveals that Secalin can be used as a biochemical marker for the confirmations of 1B/1R translocations.

    Abstract In recent periods, a broad assortment of continual organic contaminants has been released into our natural water resources. Indeed, it is exceedingly poisonous and perilous to living things; thus, the elimination of these organic pollutants before release into the water bodies is vital. A variety of techniques have been utilized to remove these organic pollutants with advanced oxidation photocatalytic methods with zinc oxide (ZnO) nanoparticles being commonly used as a capable catalyst for contaminated water treatment. Nevertheless, its broad energy gap, which can be only stimulated under an ultraviolet (UV) light source, and high recombination pairs of electrons and holes limit their photocatalytic behaviors. However, numerous methods have been suggested to decrease its energy gap for visible regions. Including, the doping ZnO with metal ions (dopant) can be considered as an effectual route not only the reason for a movement of the absorption edges toward the higher (visible light) region but also to lower the electron-hole pair (e

    Abstract A green strategy of using citric acid as both an extractant and a cross-linking agent to expel and esterify ulvan – a marine polysaccharide from foliose Ulva sp. and filamentous Ulva sp. for hydrogel preparation was developed. Ulva sp. biomass of two different morphologies, foliose and filamentous Ulva sp., was collected from the Spiddal coast of Ireland to extract ulvan using a novel citric acid method which compared with conventional hydrochloric acid or water-based extraction methods. Extraction process parameters, viz. Ulva sp. load, extraction time, extraction temperature, and citric acid concentration, were optimised using the Taguchi experimental design. The optimised process parameters were 3 wt%, 4 h, 90 °C, and 1 wt%, respectively, for foliose and filamentous Ulva sp. At the optimised conditions, a maximum of 0.41 (±0.02) g/g and 0.39 (±0.04) g/g of ulvan yield with a protein content of 0.010 (±0.003) g/g and 0.007 (±0.002) g/g (dry weight basis) were obtained, respectively. This ulvan yield by citric acid-based extraction was superior in comparison with conventional hydrochloric acid (0.29 g/g) and water (<0.1 g/g) based extraction. Extracted ulvan was characterised and compared with commercial ulvan using proton - Nuclear Magnetic Resonance (NMR), Fourier transform infrared (FTIR) spectroscopy, and differential scanning spectroscopy (DSC) analysis. Extracted ulvan was cross-linked with 2 wt% of citric acid to form hydrogel, and the cross-linking mechanism was found to be an esterification reaction using FTIR spectroscopy. Hybridization of ulvan with varying proportions of sodium carboxymethyl cellulose (Na-CMC) was carried out to uncover the broad applications of the hydrogel in health care, agriculture, and environmental fields.

    Abstract Objective: To determine the effect of facial neuromuscular re-education over conventional therapeutic measures in improving facial symmetry in patients with Bell's palsy.
    Design: Randomized controlled trial.
    Setting: Neurorehabilitation unit.
    Subjects: Fifty-nine patients diagnosed with Bell's palsy were included in the study after they met the inclusion criteria. Patients were randomly divided into two groups: control (n = 30) and experimental (n = 29).
    Interventions: Control group patients received conventional therapeutic measures while the facial neuromuscular re-education group patients received techniques that were tailored to each patient in three sessions per day for six days per week for a period of two weeks.
    Main measures: All the patients were evaluated using a Facial Grading Scale before treatment and after three months.
    Results: The Facial Grading Scale scores showed significant improvement in both control (mean 32 (range 9.7-54) to 54.5 (42.2-71.7)) and the experimental (33 (18-43.5) to 66 (54-76.7)) group. Facial Grading Scale change scores showed that experimental group (27.5 (20-43.77)) improved significantly more than the control group (16.5 (12.2-24.7)). Analysis of Facial Grading Scale subcomponents did not show statistical significance, except in the movement score (12 (8-16) to 24 (12-18)).
    Conclusion: Individualized facial neuromuscular re-education is more effective in improving facial symmetry in patients with Bell's palsy than conventional therapeutic measures.
