UV-Visible-NIR Camouflage Textiles with Natural Plant Based Natural Dyes on Natural Fibre against Woodland Combat Background for Defence Protection
Authors: Hossain Md. Anowar 
Published: January 2023

Abstract
Natural plant based natural dyes (NPND) is a common source of woodland combat background (CB). Swietenia Macrophylla, Mangifera Indica, Terminalia Arjuna, Corchorus Capsularis, Camellia Sinensis, Azadirachta Indica, Acacia Acuminata, Areca Catechu and Cinnamomum Tamala were powdered/extracted and dyed-coated-printed with leafy design on cotton textiles and tested against woodland CB under the reflection engineering of ultraviolet (UV)-visible (Vis)-near infrared (NIR) spectrum and photographic technique of Vis imaging. The reflection properties of NPND treated and untreated textiles were experimented by UV-Vis-NIR spectrophotometer from 220 nm to 1400 nm. A field trialling of NPND treated woodland camouflage textiles was also investigated, located at Madhupur forest, Tangail, Dhaka, Bangladesh. The imaging properties such as CIE L*, a*, b* and RGB (red, green, blue) of NPND treated textiles were trialled by digital camera against tree stem/bark, dry leaves and green leaves of woodland CB. Therefore, a colorful matching with woodland CB (natural plant Shorea Robusta Gaertin, a common tree of woodland CB) was verified by Vis camera imaging and UV-Vis-NIR reflection mechanism. UV-protection property of Swietenia Macrophylla treated fabric was also investigated by diffuse reflection for defence clothing. Therefore, simultaneous ‘camouflage textiles in UV-Vis-NIR’ and ‘UV-protective’ property of Swietenia Macrophyllatreated fabric has been investigated for NPND materials-based textiles coloration (dyeing-coating-printing) which is a new concept for camouflage formulation of NPND-dyed-coated-printed textiles in terms of ecofriendly camouflage materials.
Maximizing the influence spread in social networks: a learning automata driven discrete butterfly optimization algorithm

Published: January 2023

Abstract
Influence maximization aims at the identification of a small group of individuals that could result in the most widely transmission of information in social networks. Although greedy-based algorithms can yield reliable solutions, the computational cost is extreme expensive especially in large-scale networks. Meanwhile, the traditional heuristics such as degree and betweenness centralities tend to suffer from the problem of low accuracy. Locating influential nodes effectively using swarm intelligence algorithms remains a research hotspot in social network analysis. To solve the influence maximization problem in an efficient way, a learning automata driven discrete butterfly optimization algorithm(LA-DBOA) mapped into the network topology is proposed in this paper. According to the LA-DBOA framework, a novel encoding mechanism and discrete evolution rules adapted to network topology are presented. A modified learning automata is adopted to guide the butterfly population towards promising areas. Based on the topological characteristics of the discrete network, a new local search strategy is conceived to enhance the search performance of the butterflies. Extensive experiments are conducted on six real networks under the independent cascade model, and the results demonstrate that the proposed algorithm outperforms the state-of-the-art methods when trade-off is made between efficiency and effectiveness.
Study on the mechanical properties of clayey slip zone soil considering montmorillonite content

Published: January 2023

Abstract
The strength property of slip zone soil determines the evolution mechanism and deformation damage of landslides. When the slip zone soil contains a certain amount of hydrophilic minerals, it, therefore, has swelling properties. These swelling properties cause the mechanical property of cohesive slip zone soils to differ from those of conventional-type of slip zone soils. Thus, four cases of typical landslide cohesive slip zone soils in the Shanxi Province of the Yellow River Basin were used as research objects to study the mechanism of hydrophilic minerals on the mechanical properties of cohesive slip zone soils. The mineral fractions of the cohesive slip zone soils were analyzed using X-ray diffraction tests, followed by direct shear tests to analyze the pattern of the shear strength parameters of cohesive slip zone soils under different hydrophilic mineral contents with water content. Finally, the free swelling rate test was used to verify that montmorillonite minerals are the main hydrophilic minerals affecting the swelling characteristics of cohesive slip zone soils. The results were as follows. The cohesion and internal friction angle of clayey slipband soils exhibited two patterns (negative exponential/negative correlation) with the variation of water content, and the critical values of the pattern of the variation of the shear strength parameters with water content were affected by montmorillonite content ranging from 17.65% to 34.52%. The shear strength attenuation of clayey slip zone soils showed a positive correlation with the change in montmorillonite content, and the swelling property caused by montmorillonite minerals was the intrinsic reason for the shear strength attenuation of clayey slip zone soils under different water content conditions. The research results explain the shear strength decay law of cohesive slip zone soils from the perspective of mineral composition and reveal the unique strength properties of these slip zone soils.

Published: January 2023

Abstract
In this paper, we investigate the characteristics of marine heatwaves (MHWs) (i.e. frequency, maximum intensity, and duration of occurrences) in Indonesian waters and the mechanisms underlying the formation of MHWs generated by local forcing. The study utilizes the remote sensing data from National Oceanic and Atmospheric Administration (NOAA) Optimum Interpolation Sea Surface Temperature (OISST) dataset for SST and the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis data (ERA5) for net surface heat flux components (shortwave radiation, longwave radiation, sensible heat flux, and latent heat flux), wind speed, and total cloud cover. The data covered a period within the last 40 years (1982–2021) during the warm (1982–2007) and cold (2008–2021) phases of the Pacific Decadal Oscillation (PDO) and were processed by statistical analysis methods. This study clearly reveals the highest average frequency and duration of MHWs in the Indonesian waters which were around 3–5 times a year and 10–20 days, respectively, occurring during the cold phase of PDO. Meanwhile, the highest maximum intensity of MHWs in the Indonesian waters was around > 1.5°C during the warm phase of PDO (El Niño dominated in Indonesia) generated by the local net surface heat flux. The most dominant contributors of net surface heat flux were high shortwave radiation (heat gain) and low latent heat flux (heat loss) through the evaporation process, thus keeping the ocean warm. Moreover, this study highlights the highest maximum intensity of MHWs which could reach > 3°C along western Sumatra to southern Java and waters around Papua when El Niño and positive Indian Ocean Dipole (pIOD) occur together. In contrast, the lowest maximum intensity of MHWs in the Indonesian waters occurred when La Niña was happening simultaneously with negative IOD (nIOD).

Abstract
Introduction: Inappropriate ventilator settings, non-adherence to a lung-protective ventilation strategy, and inadequate patient monitoring during mechanical ventilation can potentially expose critically ill children to additional risks. We set out to improve team theoretical knowledge and practical skills regarding pediatric mechanical ventilation and to increase compliance with treatment goals.
Methods: An educational initiative was conducted from August 2019 to July 2021 in a neonatal and pediatric intensive care unit of the University Children's Hospital, Hamburg-Eppendorf, Germany. We tested baseline theoretical knowledge using a multiple choice theory test (TT) and practical skills using a practical skill test (PST), consisting of four sequential Objective Structured Clinical Examinations of physicians and nurses. We then implemented an educational bundle that included video self-training, checklists, pocket cards, and reevaluated team performance. Ventilators and monitor settings were randomly checked in all ventilated patients. We used a process control chart and a mixed-effects model to analyze the primary outcome.
Results: Staff members took part in 183 theory tests (TT) and 169 practical skill tests (PST). The initiative was associated with a substantial increase in staff TT and PST performance (CI) (TT: 80 [77.2–82.9]% vs. 86 [83.1–88.0]%, PST: 73 [69.7–75.5]% vs. 95 [93.8–97.1]%), self-confidence, and compliance with mechanical ventilation treatment goals (87.8% vs. 94.5%).
Discussion: Implementing a pediatric mechanical ventilation education bundle improved theoretical knowledge and practical skills among multi-professional pediatric intensive care staff and increased treatment goal compliance in ventilated children.

Published: January 2023

Abstract
The portal-scaffold complex is believed to nucleate the assembly of procapsids of herpesviruses. During capsid maturation process, two events occur: expulsion of the scaffold and the incorporation of DNA. The portal-scaffold interaction and the conformational changes to the portal during the different stages of capsid assembly and maturation have yet to be elucidated structurally. Here, we present high-resolution structures of the A- and B-capsids and in-situ portals of human cytomegalovirus. We show that scaffolds bind to the hydrophobic cavities formed by the dimerization and Johnson-fold domains of the major capsid proteins. We further show that 12 loop-helix-loop fragments, presumably from the scaffold domain of the scaffold, insert into the hydrophobic pocket of the portal crown domain. The portal also undergoes significant changes both positionally and conformationally accompanying DNA packaging. These findings not only provide insights into how the portal interacts with the scaffold proteins to nucleate capsid assembly but further our understanding of the mechanism of scaffold expulsion and DNA incorporation during maturation.
Generation mechanisms of strange nonchaotic attractors and multistable dynamics in a class of nonlinear economic systems
Authors: Li Gaolei , Duan Jicheng , Li Denghui , Wang Na 
Published: January 2023

Abstract
In this paper we study strange nonchaotic attractors (SNAs) and multistable dynamics in a class of nonlinear economic systems. For quasiperiodically forced case, the generation and evolution mechanisms of SNAs are discussed. The fractal, Heagy–Hammel, torus doubling, and intermittency routes to SNAs are identified. The Lyapunov exponent, phase sensitive function and power spectrum are used to characterize the dynamical and geometrical properties of SNAs. Moreover, when multistable phenomenon occur in the system, the boundaries of the basin of attraction may become intertwined, which leads to the economic unpredictability in the long run.

Abstract
Background
Syria has been in continuous conflict since 2011, resulting in more than 874000 deaths and 13.7 million internally displaced people (IDPs) and refugees. The health and humanitarian sectors have been severely affected by the protracted, complex conflict and have relied heavily on donor aid in the last decade. This study examines the extent and implications of health aid displacement in Syria during acute humanitarian health crises from 2011 to 2019.
Methods
We analysed data on humanitarian and health aid for Syria between 2011 and 2019 from the OECD’s Creditor Reporting System. We linked the data obtained for health aid displacement to four key dimensions of the Syrian conflict. The data were compared with other fragile states. We conducted a workshop in Turkey with a panel of experts and key informants with experts, policy makers and aid practitioners involved in the humanitarian and health response in Syria between August and October 2021 to corroborate the quantitative data obtained by analysing aid repository data.
Results
The findings suggest that there was health aid displacement in Syria during key periods of crisis by a few key donors, such as the EU, Germany, Norway and Canada supporting responses to certain humanitarian crises. However, considering that the value of humanitarian aid is 50 times that of health aid, this displacement cannot be considered as critical. Also, there was unclear evidence of health displacement across all donors.
The results also showed that the value of health aid as a proportion of aggregate health and humanitarian aid is only 2% in Syria, compared to 22% for the combined average of fragile states, which further indicates the predominance of humanitarian aid over health aid in the Syrian crisis context.
Conclusion
This study highlights that in very complex conflict-affected contexts such as Syria, it is difficult to suggest the use of health aid displacement as an effective tool for aid-effectiveness for donors as it does not reflect domestic needs and priorities. Yet there seems to be evidence of slight displacement for individual donors. However, we can suggest that donors vastly prefer to focus their investment in the humanitarian sector rather than the health sector in conflict-affected areas. There is an urgent need to increase donors’ focus on Syria’s health development aid and adopt the humanitarian-development-peace nexus to improve aid effectiveness that aligns with the increasing health needs of local communities, including IDPs, in this protracted conflict.

Abstract
Acute respiratory distress syndrome (ARDS) causes significant morbidity and mortality during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections1,2. Nevertheless, most patients with coronavirus disease 2019 (COVID-19) recover seamlessly without developing ARDS3, suggesting the existence of endogenous pathways to protect the lungs. Since many microRNAs (miRNAs) serve important roles in endogenous regulatory pathways, we pursued functional roles of miRNAs in COVID-19-ARDS. A screen of miRNAs in human alveolar epithelia or mice infected with SARS-CoV-2 identified miR-147 as a lead candidate. Transcriptional analysis implicated hypoxia-inducible factor 1A (HIF1A) in miR-147 induction during alveolar injury or SARS-CoV-2 infection. Functionally, mice with alveolar epithelial deletion of miR-147 showed increased lung injury in response to SARS-CoV-2 infection. mRNA sequencing and subsequent in silico miR-147-target analysis revealed reduced antiviral responses and identified SARS-CoV-2 ORF8 as a direct miR-147 target. Moreover, mice infected with SARS-CoV-2 and treated with miR-147 packaged in DOPC nanoliposomes showed significant protection with enhanced antiviral responses and improved survival. Finally, proof-of-principle studies in patients with COVID-19 highlighted this pathway in human SARS-CoV-2-associated ARDS. Together, our findings identify a previously unrecognized role of miR-147 in lung protection during viral pneumonia by attenuating immune evasion of SARS-CoV-2.
Energy-Efficient Data Transmission with Proportional Rate Fairness for NANs of Smart Grid Communication Network

Published: January 2023

Abstract
In smart grid, the neighborhood area network (NAN) serves as a bridge connecting smart meters and meter data management system (MDMS) and is one of the most important components of the smart grid communication network. In this work, we study the energy-efficient data transmissions from NAN gateways (i.e., routers) to the concentrator that connects the MDMS. Particularly, to assure that each router associated with diverse number of associated smart meters can achieve a required data rate, a set of proportional rate fairness constraints are imposed into the optimization problem. In this case, an optimization problem that balances energy efficiency and fairness is formulated. Due to the fractional form of objective function, the combinatorial constraints on channel allocation variables, and the proportional rate fairness requirements, the formulated energy-efficient data transmission problem is non-convex and extremely computationally complex. In order to solve the problem efficiently, firstly, a subtractive transformation is introduced to handle the objective function, and an iterative algorithm based on Dinkelbach method is proposed; then for the inner loop optimization problem in each iteration, a low-complexity suboptimal algorithm that separates channel allocation and power distribution is developed. Finally, numerical results demonstrate that the proposed algorithm converges in a few steps and achieves a near-optimal energy efficiency performance.
Behavior and mechanisms of ciprofloxacin adsorption on aged Polylactic Acid and Polyethylene microplastics
Authors: Liang Jinni , Wu Jiahui , Zeng zhi , Li Manzhi , Liu Weizhen , Zhang Taiping 
Published: January 2023

Abstract
Microplastics (MPs) and antibiotics are emerging pollutants in aquatic environments. MPs can absorb antibiotics in the environment, resulting in compound pollution. The relationship between the physicochemical properties of aged microplastics and the adsorption of CIP was investigated to assess the control on the fate and transport of CIP in the environment. The adsorption capacity decreased in the following sequence: aged PLA > PLA > aged PE > PE. The experiment data matched the pseudo-secondary dynamics and the Langmuir isotherm model well, implying that adsorption was primarily governed by monolayer chemisorption. When the solution's pH was close to the dissociation constant (pKa) of CIP, the sorption capacity of MPs increased. The greater the concentration of Na+ and fulvic acid, the stronger the inhibition of adsorption. The adsorption effect of microplastics on CIP was more strongly inhibited by norfloxacin (NOR) at lower concentrations (CNOR＜CCIP). Based on the adsorption data, FTIR, and XPS spectra, we demonstrated that the adsorption process was a non-spontaneous heat absorption reaction, with chemical and physical mechanisms including hydrogen bonding, π-π conjugation, ion exchange, and electrostatic interactions controlling it. This study's discovery of the mechanism of interaction between MPs and CIP serves as a foundation for assessing the environmental risk of MPs and antibiotic complex contamination.
A new approach to the solution of a modified single item continuous production inventory problem
Authors: Dey Debopriya , Kar Samarjit , Bhattacharya Dilip Kumar 
Published: January 2023

Abstract
The paper studies critically different types of single item continuous Production Inventory models with regard to the existence of their solutions. The aim is to calculate the minimum value of the objective function based on the total cost involved in the whole process. As the problems are solved by Pontryagin’s maximum principle, so the solution reduces to the solution of a pair of ordinary differential equations. One corresponds to the state dynamics and the other one corresponds to the co-state dynamics; the latter one is to be solved in reverse time. Therefore, the solution is not possible to obtain, in general. But it is known that the models of standard continuous linear quadratic regulators are almost similar to those of continuous production inventory models and at the same time they can be solved completely under a proper choice of the transition matrix. So, the present paper first finds out the production inventory model, which is the most general amongst all such existing inventory models. Next it makes suitable modifications of this general existing model of continuous production inventory in the exact form of linear quadratic regulator in order to assure the existence of its solutions. Once the solution is assured, the paper tries to solve the model completely in the form of obtaining the optimal production rate and optimal inventory level. In this connection, some additional restrictions are imposed on the model, so that the necessary transition matrix be available to get the final solution. Finally, the whole analysis is subjected to some special choice of the parametric functions involved in the system. The resulting solutions in the form of optimal production rate and optimal inventory level are shown graphically and they are interpreted properly from their graphs.

Abstract
Heterohelicenes are of increasing importance to the field of material science, molecular recognition, and asymmetric catalysis. However, the enantioselective construction of heterohelicenes, especially by organocatalytic method, remains rare and challenging. Herein, enantioenriched 1-(3-indol)-quino[5]helicenes have been synthesized through chiral phosphoric acid catalyzed Povarov reaction, followed by an oxidative central-to-helical chirality conversion process. The reaction has a broad scope and offers rapid access to an array of chiral quinohelicene derivatives with pretty enantioselectivities (up to 99% ee). Furthermore, optical properties of the studied quinohelicenes have been disclosed.
