    Cross-Lagged Relationship between Physical Activity Time, Openness and Depression Symptoms among Adolescents: Evidence from China

    Xiaojie Cao1, Qinyu Zhang2, Xinqiao Liu3,*

    International Journal of Mental Health Promotion, Vol.25, No.9, pp. 1009-1018, 2023, DOI:10.32604/ijmhp.2023.029365

    Abstract The relationship between physical activity time, openness and depression symptoms among adolescents is a cutting-edge research direction in the field, yet it remains unclear. This study is based on a sample of 7924 students from a nationally representative China Education Panel Survey database and examines the bidirectional relationships between physical activity time, openness and depression symptoms among Chinese adolescents. Descriptive analysis showed that during the 7th and 8th grades, the average physical activity time decreased to less than one hour per day, accompanied by a decreasing trend in openness and a slight worsening in depression symptoms. Correlation analysis showed a… More >

    M. Atikur Rahman*, Amranur Rahman, Arman Hossain, Arifur Rahman Bhuiyan

    Journal of New Media, Vol.5, No.1, pp. 33-43, 2023, DOI:10.32604/jnm.2023.038676

    Abstract As a result of the introduction of new infectious illnesses, key infection prevention measures were implemented. Now, a new coronavirus (SARS-CoV-2) epidemic has expanded swiftly, causing the coronavirus illness 2019 (COVID-19). Many microorganisms spread illness via hospital surfaces due to environmental pollution. This virus has been associated to close contact between persons in tight situations such as houses, hospitals, assisted living, and residential institutions. Aside from health care settings, public buildings, faith-based community centers, marketplaces, transportation, and corporate environments are prone to COVID-19 transmission. Physical contact to the sanitizer device may cause for spread Covid virus. That’s why we have… More >

    Temperature-Triggered Hardware Trojan Based Algebraic Fault Analysis of SKINNY-64-64 Lightweight Block Cipher

    Lei Zhu, Jinyue Gong, Liang Dong*, Cong Zhang

    CMC-Computers, Materials & Continua, Vol.75, No.3, pp. 5521-5537, 2023, DOI:10.32604/cmc.2023.037336

    Abstract SKINNY-64-64 is a lightweight block cipher with a 64-bit block length and key length, and it is mainly used on the Internet of Things (IoT). Currently, faults can be injected into cryptographic devices by attackers in a variety of ways, but it is still difficult to achieve a precisely located fault attacks at a low cost, whereas a Hardware Trojan (HT) can realize this. Temperature, as a physical quantity incidental to the operation of a cryptographic device, is easily overlooked. In this paper, a temperature-triggered HT (THT) is designed, which, when activated, causes a specific bit of the intermediate state… More >

    Frontiers in Heat and Mass Transfer, Vol.19, pp. 1-10, 2022, DOI:10.5098/hmt.19.39

    Abstract In this study, the hydrothermal water flow characteristics using a dimpled inner tube heat exchanger are investigated experimentally and numerically. A numerical analysis has performed on two types of dimpled tubes (In-lined and staggered distributions) for two distribution angles 60o and 90o , and two dimple diameters(4 mm and 6 mm) with constant pitch ratio (X/d=8). In experimental part, a staggered arrangement dimpled inner tube distribution with angle 60o , dimple diameter of 6 mm and constant pitch ratio (X/d=8)is used as well as plain tube. The results illustrate that the heat transfer as Nusselt number for case of staggered… More >

    Abstract This analytical study has been carried out on inline and staggered hole jet plate solar air heater with longitudinal fins attached underside the absorber surface under the cross flow and non-cross flow conditions of air through the channels for varying mass flow rate of air, ṁ1 (50-300 kg/hm2 ), jet hole diameter, D (6 mm-10 mm) and distance between the absorber and jet plate, Z2 (5 cm-10 cm) with fixed number of jet holes, N (480 and 1008 for inline and staggered hole respectively) and pitch of the fins, p (3 mm). The result shows the performance of staggered hole… More >

    Abstract Inserting the jet plate between the bottom plate and absorber plate in a flat plate solar air heater has been proposed as an excellent option to enhance the performance of the conventional solar air heater. This research work presents an experimental study of flow and heat transfer in a jet plate solar air heater. Results are presented for the different mass flow rates of air ṁ1 and ṁ2, Reynolds number Reja2, streamwise pitch of the holes to jet hole diameter X/D, depth of upper channel to jet hole diameter Z2/D, fixed number of jet hole N and angle of tilt… More >

    Lack of Tocopherol Inhibits Rice Growth by Triggering an Ectopic Stress Response and the Accumulation of DELLA Protein

    Di Wang1,#,*, Hao Gao1,#, Jian Wang1, Baoshan Cheng1, Gang Li1, Weijun Xu1, Xi Liu2,3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1173-1183, 2023, DOI:10.32604/phyton.2023.026526

    Abstract Although tocopherols are essential for rice development, the molecular details by which their absence affects development remain to be determined. To study how tocopherols function during rice development, we performed a transcriptome deep sequencing (RNA-seq) analysis of the rice cultivar Nipponbare (Nip) and the tocopherol-deficient mutant small grain and dwarf 1-2 (sgd1-2). We identified 563 differentially expressed genes that were enriched in Gene Ontology categories associated with metabolism, stress, cellular responses, and transcriptional regulation. We determined that the total fatty acid composition of Nip and sgd1-2 was comparable, although cell membrane penetrability in sgd1-2 was significantly higher than in Nip… More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.3, pp. 883-899, 2023, DOI:10.32604/phyton.2023.025022

    Abstract Ensuring food security for the rapidly increasing population and changing climatic scenarios are requisites for exploiting the genetic divergence of food crops. A study was undertaken to sort out an early maturing chickpea variety for fitting easily between rice-rice cropping systems in the Eastern Indo-Gangetic Plain of Bangladesh. The trial was comprised of eight elite lines of chickpea and executed at various localities in Bangladesh from 2014– 15 to 2017–18. The result explored the chickpea genotype, BARI Chola-11 remained superior to the rest of the elite genotypes for having a short maturity period (100–106 days), and lesser days to 50%… More >

    Self-Triggered Consensus Filtering over Asynchronous Communication Sensor Networks

    Huiwen Xue1, Jiwei Wen1,*, Akshya Kumar Swain1, Xiaoli Luan1

    CMES-Computer Modeling in Engineering & Sciences, Vol.134, No.2, pp. 857-871, 2023, DOI:10.32604/cmes.2022.020127

    Abstract In this paper, a self-triggered consensus filtering is developed for a class of discrete-time distributed filtering systems. Different from existing event-triggered filtering, the self-triggered one does not require to continuously judge the trigger condition at each sampling instant and can save computational burden while achieving good state estimation. The triggering policy is presented for pre-computing the next execution time for measurements according to the filter’s own data and the latest released data of its neighbors at the current time. However, a challenging problem is that data will be asynchronously transmitted within the filtering network because each node self-triggers independently. Therefore,… More >

    Improved Staggered Algorithm for Phase-Field Brittle Fracture with the Local Arc-Length Method

    Zhijian Wu, Li Guo*, Jun Hong

    CMES-Computer Modeling in Engineering & Sciences, Vol.134, No.1, pp. 611-636, 2023, DOI:10.32604/cmes.2022.020694

    Abstract The local arc-length method is employed to control the incremental loading procedure for phase-field brittle fracture modeling. An improved staggered algorithm with energy and damage iterative tolerance convergence criteria is developed based on the residuals of displacement and phase-field. The improved staggered solution scheme is implemented in the commercial software ABAQUS with user-defined element subroutines. The layered system of finite elements is utilized to solve the coupled elastic displacement and phase-field fracture problem. A one-element benchmark test compared with the analytical solution was conducted to validate the feasibility and accuracy of the developed method. Our study shows that the result… More >
