Published: August 2023

Abstract

Plastic wastes are integrated with renewable wood fiber (WF) into wood-plastic composites (WPC), which is an economically sustainable way to solve global plastic pollution. However, the current processing strategies are applied mainly to single-polymer wastes, but are ineffective for mixed-waste streams. Herein, we proposed a simple and effective strategy to upcycle mixed plastic wastes to prepare WPC via solid-state shear milling (S3M). Specially, the mixed plastic waste, WF and maleic anhydride grafted polyethylene were co-milled in solid-state. During the mechanical treatment, the bevel ridges on the upper and lower pans in the S3M equipment created many mixing units to continuously exert strong squeezing and shearing forces on the milling composites, enabling mechanically-induced pulverization, dispersion and esterification of the multi-component materials at room temperature. As a result, the mixed plastic wastes with WF were pulverized and mixed simultaneously while hydrophilic WF was transformed to the hydrophobic one, endowing the obtained WPC with exhibited excellent processability and strong interfacial interaction. The flexural strength and modulus reached 39.5 MPa and 4257 MPa, with 72% and 101% enhancement compared to the WPC sample with the same formulation prepared by direct melt-process. This mechanochemistry technology can successfully achieve the upgrading and reuse of mixed plastic wastes and solve the challenges associated with the WF preparation, which plays a crucial role in mitigating plastic pollution.
Both frequency and diversity of childhood nature experiences are associated with self-reported pro-biodiversity behaviors in adulthood

Published: August 2023

Abstract
The ongoing degradation of Earth’s ecosystems through human activities poses a severe threat to biodiversity. To mitigate this crisis, substantial changes in human behavior are required. The frequency of nature experiences, particularly during childhood, has been established as a key predictor of actions that support biodiversity (hereafter, pro-biodiversity behaviors). However, the significance of the quality of these experiences remains poorly understood. In this study, we analyzed a large sample of Japanese adults and observed positive associations between both the frequency and diversity of nature experiences during childhood and increased pro-biodiversity behaviors. These associations held true across a range of behaviors, including the purchase of eco-friendly products, reduced use of pesticides in domestic gardens, and contributions to conservation organizations. Our findings indicate that the association between pro-biodiversity behaviors and the diversity of childhood nature experiences is comparable to that of the frequency of such experiences. These findings suggest that expanding people’s access to diverse and frequent nature experiences can play a crucial role in promoting positive behavioral changes to prevent biodiversity loss.

Abstract
We present new mineralogical data of cronstedtite from the Southern-2 orebody, located in the South-Western branch of the Talnakh intrusion (Noril'sk camp) composed of massive sulfides in which the total amount of oxides and silicates does not exceed 1–3 vol. %. The petrographic and mineralogical features of these ores indicated occurrence of fine-grained, fibrous needle like clusters <50-µm-sized grains of cronstedtite (7,09 Å along its c-axis). This mineral confirmed by a number of analytical techniques (powder X-ray diffraction of balk samples, transmission electron microscopy, scanning electron microscopy, Raman and Infrared spectroscopy). Cronstedtite contains impurities of Al, Ni, Ca and filling the cracks between sulfides of copper (chalcopyrite) and iron (pyrrhotite, pentlandite, troilite). In some cases, cronstedtite contains micron-sized PGE, and associates with magnetite, kaolinite, gypsum, calcite, quartz, and cristobalite. The findings of cronstedtite in Noril'sk camp have never been mentioned publicly before. Its occurrence is the northernmost known locality in the world. Our results imply that the formation of cronstedtite in the Talnakh intrusion could be possible by the active participation low-temperatures fluids within the relatively near-surface (<2 km of paleosurface) conditions of intrusion emplacement, in contrast to other deep-seated supergiant Cu-Ni-PGE deposits in the world.

Authors: Li Dongrui , Li Fan , Jin Jingyu , Yang Yang , Tong Qian 
Published: August 2023

Abstract
Background
The association between gut microbiota and pulmonary arterial hypertension (PAH) has been found in some observational studies. However, whether this association implies a causal relationship remains unclear.
Methods
In this study, we employed summary data from genome-wide association studies (GWAS) of the gut microbiota and PAH to investigate the causal relationship between the gut microbiota and PAH using a two-sample Mendelian randomization (MR) design. Comprehensive sensitivity analyses were conducted to ensure the robustness of the results.
Results
The MR results indicated that genetically predicted abundance of Lachnospiraceae ND3007 group (OR (95% CI):0.251(0.175 ~ 0.360), adjusted P value:<0.001) and Eubacterium fissicatena group (OR (95% CI):0.525(0.411 ~ 0.669), adjusted P value:<0.001) were significantly associated with a reduced risk of PAH. Additionally, we identified 12 gut microbiota, including Eubacterium ventriosum and Ruminococcus torques, that may have potential causal relationships with PAH.
Conclusion
This study suggests that specific gut microbiota may influence the incidence of PAH. This provides the evidence for a causal relationship between gut microbiota and PAH, thus offering novel insights into the therapeutic and mechanistic research of PAH.

Authors: Moallem Mohammadjavad Mirzazadeh , Korki Mehdi 
Published: August 2023

Abstract
In this paper, we present a study on partial-diffusion least mean-square (PDLMS) strategy in distributed wireless sensor networks (WSNs) in presence of wireless channel impairments, such as path loss, fading, and additive noise. Our main focus is to demonstrate the stability of the PDLMS algorithm in both the mean and mean-square sense, even in the presence of channel distortion. Additionally, we analyze the convergence behavior of the algorithm under these challenging conditions. To further enhance the performance of PDLMS over fading channels, we propose an optimal combination matrix obtained by minimizing the steady-state mean-square deviation (MSD). This matrix allows us to mitigate the performance degradation resulting from wireless channel distortions.The efficacy of our proposed optimal PDLMS method is validated through extensive simulations, which provide substantial evidence supporting the theoretical findings of this study.

Abstract
The Automatic Self Balancing Robot for Monitoring of Crop is a novel robotic system designed for the agricultural industry to improve crop monitoring and management. The robot is equipped with sensors, cameras, and machine learning algorithms that enable it to navigate through fields, collect da-ta on plant health, and identify potential issues here in this case fruit ripening (Early ripe, partially ripe, Ripe and Decay) with the help of camera. The self-balancing feature of the robot allows it to operate on uneven terrain, ensuring stable and accurate data gathering. Data gathered by the robot such as tempera-ture, humidity and soil moisture are sent to a central system for analysis, ena-bling agricultural producers to decide on crop management. The use of this ro-botic system can increase productivity, reduce employment costs, and improve overall harvest yields PID control, a feedback control loop, modifies the robot's behaviors in response to the discrepancy between the desired and actual states. A mathematical process called Kalman filtering is used to calculate and remove noise from sensor measurements, enabling more precise data interpretation. To improve the overall impression of the robot's orientation, sensor fusion com-bines data from several sensors, such as gyroscopes and accelerometers. IMUs are sensor bundles with integrated sensors that provide information on rotation, acceleration, and magnetic field strength, allowing for accurate measurement and control.

Authors: Alqahtani Abdulrahman Saad 
Published: August 2023

Abstract
One of the most crucial strategies for allowing us to carry on with normal life both during and after the pandemic is the smart city. The goal of the smart city is to serve the community and enhance the services offered to the populace, particularly in areas as important as health, education, electricity, transportation, and communications. The Internet of Things (IoT) platform offers seamless data transmission and analysis in real time between optical devices and the cloud infrastructure. Cities may enhance several areas of urban life, such as traffic control, video surveillance, environmental monitoring, and infrastructure maintenance, by utilizing the power of optics and IoT. Optical sensors can detect air quality, noise levels, and weather conditions, providing important information for environmental management and public health programs. Intelligent analytics-equipped video surveillance cameras can improve security by spotting and immediately notifying authorities of questionable activity. This research covers two cutting-edge IoT applications for smart cities: The first involves creating an intelligent health monitoring system that aims to lessen work strain on the medical personnel and the spread of Coronavirus infection from patients to the medical staff. The second use deals with measuring and monitoring electrical characteristics and energy consumption to keep track of electrical energy used. Additionally, knowing the trespasser on the electrical line is helpful. Both systems collect data from sensors in real time and send it to a server.

Published: August 2023

Abstract

Background
LSTM has been presented to overcome the problem of the gradient explosion and explosion. Tree-LSTM could improve the parallel speed of LSTM, and incorporate relevant information from dependency or syntax trees. Tree-LSTM can update gate and memory vectors from multiple sub-units. Learning edge features can strengthen the expression ability of graph neural networks. However, the original Child-Sum Tree-LSTMs ignores edge features during aggregating the sub-nodes hidden states.
Methods
we propose an interaction mechanism that can alternately updating nodes and edges vectors, thus the model can learn the richer nodes vectors. The interaction mechanism attaches the node embedding to its connected link at the first stage. Next, it superimposes the updated edge into the parent node once more. Repeat the above steps from bottom to top. We present five strategies during the alternant renewal process. Meanwhile, we adopt two constituent parsers and two dependency parser to produce the diversified formats, and compare their performances in the experiment result.
Results
The proposed model obtains the best performance compared with other methods on the BioNLP’09 and MLEE corpuses.
Conclusion
The experimental results confirm the effectiveness of the interactive mechanism. The parsing results have little impact on the final model performance, but different parsing formats have different results. CoNLL’2008 Dependencies show competitive and superior performance for each parser.
Boundary value problems in a theory of bending of thin micropolar plates with surface elasticity
Authors: Gharahi Alireza 
Published: August 2023

Abstract
We generalize a recent theory of bending of thin micropolar plates by incorporating surface effects through the modeling of plate surfaces as adjacent two-dimensional micropolar elastic bodies. By incorporating both elastic surface effects and the micropolar elastic behavior of the plate, the proposed model is capable of taking into account the contribution of high surface-to-volume ratios as well as the influence of microstructural mechanics at micro/nano scales. We determine the fundamental solution of the resulting system of equations and establish uniqueness results for the corresponding Dirichlet and Neumann boundary value problems. Moreover, we provide a numerical example to demonstrate the efficiency of the model in representing the size-dependence arising from various factors that incorporate characteristic lengths. Furthermore, we showcase the sensitivity of the results to different types of characteristic lengths present in the model.
Political and Psychosocial Antecedents of Self-Rated Successful Aging among Young-Old and Old-Old Adults
Authors: Turska-Kawa Agnieszka , Pilch Irena 
Published: August 2023

Abstract
Due to the demographic growth of older population segments, psychological research is increasingly devoted to the determinants of successful aging. The current study investigates the relationship between older people’s self-perception of aging and its potential political and psychosocial antecedents. We concentrate on a subjective aspect of successful ageing, so we refer to these self-perceptions as self-rated successful ageing. We examine two groups of potential antecedents of self-rated successful ageing associated with political participation (political subjectivity and political agency) and the resources that an individual possesses: personal (a sense of autonomy) and social (perceived social support). Informed by previous research, our study compares two age-separated groups of older people—conveniently labeled the Young-Old (Y-O), aged 65–74, and the Old-Old (O-O), aged 75–95. In line with prior findings, our regressions confirm the importance of autonomy as a positive self-rated successful ageing predictor among the elderly, regardless of whether they fall into the Y-O or O-O group. Political subjectivity, however, turns out to be a significant predictor of self-rated successful ageing only in the Y-O group of the elderly.

Published: August 2023

Abstract
Purpose
Acetaminophen is widely used among humans as an antipyretic and analgesic. In this study, the protective effect of losartan in hepatotoxicity and nephrotoxicity induced by acetaminophen in mice was investigated owing to its anti-inflammatory and antioxidant effects.
Methods
A single dose of 500 mg/kg (i.p.) acetaminophen was injected to induce hepatotoxicity and nephrotoxicity in mice. 1, 3 and 10 mg/kg (i.p.) losartan was injected twice, 1 and 12 hours after the acetaminophen injection. In addition, 4 mg/kg dose of GW9662 (Peroxisome proliferator-activated receptor gamma (PPAR-γ) antagonist) was injected 30 minutes before (i.p.) losartan injections. Samples from animals were collected 24 hours after acetaminophen injection.
Results
Losartan decreased aspartate aminotransferase (AST), alanine aminotransferase (ALT), and increased creatinine levels. Interleukin-1β, -6, -8, -10, -17, tumor necrosis factor (TNF-α) levels were returned to normal by losartan. Losartan, total antioxidant level (TAS), Total oxidant level (TO), Glutathione (GSH), Oxidized glutathione (GSSG), Malondialdehyde (MDA), Superoxide dismutase (SOD), Catalase (CAT), Glutathione peroxidase (GPx) levels, returned to normal levels. Histopathological changes in liver and kidney tissue were alleviated by losartan. The substance GW9662 increased the protective effect of losartan.
Conclusion
In light of all the data obtained from our study, it can be said that losartan has a protective effect on liver and kidney damage induced by acetaminophen due to its antioxidant and anti-inflammatory effects. In terms of the study, losartan was found to be an alternative substance that could protect people from the harmful effects of acetaminophen.

Abstract
Metabolic syndrome (MetS) has impact on arrhythmia pathogenesis includes changes in QT-interval, reflecting time-course of ventricular myocyte action potentials (APs), while long or short QT-interval is associated with ventricular arrhythmias, further leading to sudden-cardiac-arrest. Cardiac conduction-system consists of distinct components besides cardiomyocytes such as non-myocytes and Cx43 via an electrotonic-conduction-coupling. Although there are well-coordination among them under physiological condition, there are important contributions of their changes in remodeling of the heart. To identify molecular mechanisms of SQT development under MetS, we investigated the involvement of non-myocyte-associated passive electrical-contribution in the cardiac remodeling by Cx43 contribution and macrophage coupling with cardiomyocytes. We used an early-state MetS rat model (with high-sucrose for 12–14 weeks), and we evaluated heart samples and freshly isolated ventricular cardiomyocytes by using both electrophysiological and histological investigations. There were significantly high heart rates and SQT in ECGs with a high ventricular contractile response to sympathetic stimulation in the MetS rats. The positive stained α-SMA and CD68 cell numbers were significantly prominent in interfibrillar spaces of hearts, together with prominent increases in expression and longitudinal cell membrane localization of phospho-Cx43. Moreover, there was a significantly shortened AP duration in the papillary muscles, at most, via increases of NaV1.5 density and decreases in L-type Ca2+-channel currents. Considering the electrotonic contribution by non-myocytes to intercellular propagation of APs with changes in phosphorylation and localization of Cx43 in the heart, we, for the first time, demonstrated that electrical-remodeling in early-stage MetS heart may be characterized by a short QT-interval with contributions of electrotonic coupling of excitable cells and non-myocytes, leading to activation of ephaptic-coupling, to be a preconditioning stimulus for development of long QT-interval in chronic MetS.
An RGB Image Encryption Scheme based on Amalgamation of 3D-Dynamical Systems and a Left Almost ring
Authors: Haider Muneeba , Sanam Nazli 
Published: August 2023

Abstract
Digital images are widely used in the areas of medicine, defense, and space technology but their safeguarding and secure transmission is becoming a prevalent issue for researchers and engineers. Image encryption techniques usually make use of commutative and associative algebraic structures like finite Galois fields and unitary commutative rings. In this paper, first, a non-associative LA-ring of order 256 is obtained using computational techniques, and then this LA-ring and the three-dimensional non-linear chaotic Rucklidge system are combined to generate three chaotic-algebraic sequences which are used to cause confusion in encryption. For the sake of diffusion, the three dimensional non-linear chaotic Genesio-Tesi system is utilized. The motivation behind using an LA ring is to boast the robustness and increase the key space due to this algebraic structure's non-associative and non-commutative properties. Furthermore, the number of control parameters has increased because of two, three dimensional chaotic systems which aid in expanding the key space and increase encryption efficiency thus providing better security. Performance metrics are carried out for encrypted images and a comparison with some of the existing chaos dependent schemes is made, proving that the suggested technique approaches the standard prime level and is good enough for encryption processes and real-time communication.

Abstract
Background : Cerebellar hematoma is thought to result from a collection of blood in the cerebellar parenchyma. It is a rare topographical form, accounting for 5-10% of hemorrhagic strokes, with an unpredictable and often dreadful prognosis.
The aim of our study is to determine the prognostic factors of cerebellar hematomas in the Neurology Department of the CHU Ignace Deen in Conakry.
Methodology: We conducted a retrospective descriptive study lasting four (4) years, from June 1, 2017 to May 31, 2021, in the neurology department of the CHU de Conakry, focusing on patients hospitalized with a cerebellar hematoma confirmed by cerebral CT scan. The variables were epidemiological, clinical, therapeutic and prognostic. Any p-value < 0.05 was considered statistically significant.
Results: A total of 33 patients, representing 9.7% of cerebellar hematomas, with a mean age of 60±12.50 years, ranging from 33 to 82 years, and a male predominance of 69.7% (sex ratio 2.3). Hypertension was the main risk factor in 87.9% of cases. The main symptoms were headache in 90.9% of cases, dizziness in 81.8% and vomiting in 60.6%. The factor associated with a favorable outcome was an ICH score≤ 2 (p-value = 0.004)). The mortality rate was 27.3%. A favorable outcome without sequelae was observed in 18.2% of cases, versus 54.6% in cases with neurological sequelae.
Conclusion: At the end of this study, we concluded that cerebellar hematoma constitutes a diagnostic and therapeutic emergency. High ICH and modified Rankin at re-entry were poor prognostic factors associated with functional sequelae and a high mortality rate.
