    Energy Engineering, Vol.121, No.2, pp. 291-313, 2024, DOI:10.32604/ee.2023.027593

    Abstract In the existing power system with a large-scale hydrogen storage system, there are problems such as low efficiency of electric-hydrogen-electricity conversion and single modeling of the hydrogen storage system. In order to improve the hydrogen utilization rate of hydrogen storage system in the process of participating in the power grid operation, and speed up the process of electric-hydrogen-electricity conversion. This article provides a detailed introduction to the mathematical and electrical models of various components of the hydrogen storage unit, and also establishes a charging and discharging efficiency model that considers the temperature and internal gas partial pressure of the hydrogen… More >

    Tian-Jiao Wei1, Guang Li1, Yan-Ru Cui1, Jiao Xie1, Xing-Ai Gao1, Xing Teng1, Xin-Ying Zhao1, Fa-Chun Guan1,*, Zheng-Wei Liang2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.1, pp. 29-43, 2024, DOI:10.32604/phyton.2023.046078

    Abstract Soil salinization is the main factor that threatens the growth and development of plants and limits the increase of yield. It is of great significance to study the key soil environmental factors affecting plant root traits to reveal the adaptation strategies of plants to saline-alkaline-stressed soil environments. In this study, the root biomass, root morphological parameters and root mineral nutrient content of two alfalfa cultivars with different sensitivities to alkaline stress were analyzed with black soil as the control group and the mixed saline-alkaline soil with a ratio of 7:3 between black soil and saline-alkaline soil as the saline-alkaline treatment… More >

    The Effect of Soil Enzymes and Polysaccharides Secreted by the Roots of Salvia miltiorrhiza Bunge under Drought, High Temperature, and Nitrogen and Phosphorus Deficits

    Yong Qin1,2, Xiaoyu Li1,2, Yanhong Wu1,2, Hai Wang3, Guiqi Han1,2,3, Zhuyun Yan1,2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.1, pp. 119-135, 2024, DOI:10.32604/phyton.2023.046075

    Abstract Root exudates serve as crucial mediators for information exchange between plants and soil, and are an important evolutionary mechanism for plants’ adaptation to environmental changes. In this study, 15 different abiotic stress models were established using various stress factors, including drought (D), high temperature (T), nitrogen deficiency (N), phosphorus deficiency (P), and their combinations. We investigated their effects on the seedling growth of Salvia miltiorrhiza Bunge and the activities of Solid-Urease (S-UE), Solid-Nitrite Reductase (S-NiR), Solid-Nitrate Reductase (S-NR), Solid-Phosphotransferase (S-PT), and Solid-Catalase (S-CAT), as well as the contents of polysaccharides in the culture medium. The results showed that the growth… More >

    Protein Disulfide Isomerase and Its Potential Function on Endoplasmic Reticulum Quality Control in Diatom Phaeodactylum tricornutum

    Yanhuan Lin1,#, Hua Du2,#, Zhitao Ye2, Shuqi Wang2, Zhen Wang2, Xiaojuan Liu2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.1, pp. 137-150, 2024, DOI:10.32604/phyton.2023.044996

    Abstract PDI is a molecular chaperone and plays an important role in Endoplasmic Reticulum quality control (ERQC). PDI participates in the refolding of the misfolded/unfolded proteins to maintain cellular homeostasis under different stresses. However, bioinformatic characteristics and potential functions of PDIs in diatom Phaeodactylum tricornutum (Pt) are still unknown so far. Hence, the genome-wide characteristics of PtPDI proteins in P. tricornutum were first studied via bioinformatic and transcriptomic methods. 42 PtPDI genes were identified from the genome of P. tricornutum. The motif, protein structure, classification, number of introns, phylogenetic relationship, and the expression level of 42 PtPDI genes under the tunicamycin… More >

    Energetic Benefits for Two Swimmers in a Circular Runway

    Danshi Liu1, Jiadong Wang1, Xuewei Mao1, Jian Deng1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.27, No.3, pp. 1-1, 2023, DOI:10.32604/icces.2023.09789

    Abstract The coordinated motion by multiple swimmers is a fundamental component in fish school. Fish swimming in a certain formation (tandem, side by side, diamond and phalanx etc.) can gain substantial energetic benefits. However, the question whether the non-straight swimming behaviors such as milling structure in other collective patterns can also gain energetic benefits remains to be explored. Based on a series of simulations on two self-propelled swimmers, we provide a viewpoint for the energetic benefits of milling pattern in collective behaviors. The trajectory and velocity of both swimmers are controlled by a PID approach. First, we demonstrate that the influence… More >

    An Explicit and Non-Iterative Moving-Least-Squares Immersed-Boundary Method and Its Applications in the Aorta Hemodynamics with Type B Intramural Hematoma

    Wenyuan Chen1, Tao Zhang2, Yantao Yang1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.27, No.3, pp. 1-1, 2023, DOI:10.32604/icces.2023.09754

    Abstract Based on the moving-least-squares immersed boundary method, we proposed a new technique to improve the calculation of the volume force representing the body boundary. For boundary with simple geometry, we theoretically analyze the error between the desired volume force at boundary and the actual force applied by the original method. The ratio between the two forces is very close to a constant and exhibits a very narrow distribution. A spatially uniform coefficient is then introduced to correct the force and can be fixed by the least-square method over all boundary markers. Such method is explicit and non-iterative, and is easy… More >

    The Nitsche’s Method and Applications in Isogeometric Analysis

    Qingyuan Hu1,*, Yuan Liang2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.27, No.3, pp. 1-2, 2023, DOI:10.32604/icces.2023.09441

    Abstract The Nitsche’s method is originally proposed as a technique to impose boundary conditions, nowadays it is widely used for isometric analysis (IGA) and corresponding topology optimization applications. Based on our previous research [1], we present a simple way to derive the Nitsche’s formulations for different kind of boundary and interface conditions, and studied this technique in the context of IGA discretization, especially for patch coupling and contact problems. The skew-symmetric variant of the Nitsche’s method is then further studied. For linear boundary or interface conditions, the skew-symmetric formulation is parameterfree. For contact conditions, it remains stable and accurate for a… More >

    Psycho-Oncologie, Vol.17, No.4, pp. 257-266, 2023, DOI:10.32604/po.2023.043340

    Abstract Introduction. No study has examined the relationship between the factor of intolerance of uncertainty and its effects on the cognitive processes among parents of a childhood cancer survivor. Intolerance of uncertainty is a central factor in generalized anxiety disorder; an anxiety disorder in which impaired processing of cognitive information in the form of cognitive biases is also observed. The aim of the study was to measure, via a classical Stroop test and an emotional Stroop test, the orientation of selective attention in relation to the uncertainty intolerance factor. Methods. 61 parents of a childhood cancer survivor (aged 4 to 6… More >

    A Narrative Review Unravelling the Historical Roots of Myths Surrounding Hypnosis and Discerning Facts

    Revue narrative pour démêler les racines historiques des mythes entourant l’hypnose et discerner les faits

    Dali Geagea*

    Psycho-Oncologie, Vol.17, No.4, pp. 215-224, 2023, DOI:10.32604/po.2023.043338

    Abstract Hypnosis, one of the earliest mind-body treatments, has been the subject of renewed interest in the last decade with research indicating its effectiveness for varied physiological and psychological ailments including pain, distress, and psychosomatic disorders. However, the adoption and acceptance of hypnosis are still hindered by myths and misconceptions that prevail among the general public and clinicians. Considering their significant role in promoting the successful delivery and acceptance of interventions, informing clinicians about hypnosis is crucial to promote balanced views, and thereby the adoption of this intervention when warranted. This narrative review traces the historical roots of myths surrounding hypnosis,… More >
