| 1 | Novel in silico EST-SSR markers and bioinformatic approaches to detect genetic variation among peach(Prunus persica L.)germplasm显示文摘Because there are thousands of peach cultivars,cultivar classification is a critical step before starting a breeding project.Various molecular markers such as simple sequence repeats(SSRs)can be used.In this study,67 polymorphic primers produced 302 bands.Higher values for SI index(1.903)suggested higher genetic variability in the genotype under investigation.Mean values for observed alleles(Na),expected heterozygosity(He),effective alleles(Ne),Nei’s information index(h),and polymorphic information content(PIC)were 4.5,0.83,5.45,0.83,and 0.81,respectively.The dendrogram constructed based on Jaccard’s similarity coefficients outlined four distinct clusters in the entire germplasm.In addition,an analysis of molecular variance(AMOVA)showed that70.68%of the total variation was due to within-population variation,while 29.32%was due to variation among populations.According to this research,all primers were successfully used for the peach accessions.The EST-SSR markers should be useful in peach breeding programs and other research. | Mehrana Koohi Dehkordi Tayebeh Beigzadeh Karim Sorkheh | 2020 | Journal of Forestry Research2020，31，4： | 2 |

| 6 | A new passive transfemoral prosthesis mechanism based on 3R36 knee and ESAR foot providing walking and squatting显示文摘Researchers have proposed various linkage mechanisms to connect knee and ankle joints for above-knee prosthe-ses,but most of them only offer natural walking.However,studies have shown that people assume a squatting posture during daily activities.This paper introduces a novel mechanism that connects the knee joint with the foot-ankle joint to enable both squatting and walking.The prosthetic knee used is the well-known 3R36,while the energy storing and return(ESAR)prosthetic foot is used for the ankle-foot joint.To coordinate knee and ankle joint movements,a six-bar linkage mechanism structure is proposed.Simulation results demonstrate that the proposed modular transfemoral prosthesis accurately mimics the motion patterns of a natural human leg during walking and squatting.For instance,the prosthesis allows a total knee flexion of more than 140°during squatting.The new prosthesis design also incorporates energy-storing mechanisms to reduce energy expenditure during walking for amputees. | Amer Imran Borhan Beigzadeh Mohammad Reza Haghjoo | 2023 | Theoretical & Applied Mechanics Letters2023，13，5： | 0 |
| 7 | 被动动态目标操作:初步定义和例子(英文)显示文摘In this work,we introduce a category of dynamic manipulation processes,namely passive dynamic object manipulation,according to which an object is manipulated passively.Specifically,we study passive dynamic manipulation here.We define the main concept,discuss the challenges,and talk about the future directions.Like other passive robotic systems,there are no actuators in these systems.The object follows a path and travels along it under the effect of its own weight,as well as the interaction force applied by each manipulator on it.We select some simple examples to show the concept.For each example,dynamic equations of motion are derived and the stability of the process is taken into account.In this direction,some rules are derived under which we ensure that the manipulation process does not fail.Simulations support this idea. | BEIGZADEH Borhan MEGHDARI Ali SOHRABPOUR Saeed | 2010 | 自动化学报2010，36，12： | 0 |
| 8 | 应用欧拉-拉格朗日方法分析动脉粥样硬化性颈动脉血流的流-固相互作用显示文摘本研究旨在模拟不同狭窄程度和脉搏率的颈动脉搏动血流。采用流-固耦合(FSI)和任意拉格朗日-欧拉(ALE)方法研究了不同狭窄程度、脉搏率和动脉壁性质对周围流体的影响。分别应用Carreau-Yasuda非牛顿超弹性模型和修正Mooney-Rivin超弹性模型于具有非牛顿行为的血液和超弹性血管壁。结果得到血液的壁面径向位移、压力分布、轴向速度分布和壁面剪切应力。通过增加狭窄的严重程度,轴向速度、血压变化、最大壁面剪切应力和壁面径向位移均呈增长趋势。当脉率在狭窄程度为75%时,最大流量矩、壁面径向位移、压力、轴向速度和壁面剪应力的最大值均增大。此外,与弹性和刚性模型相比,将动脉壁视为超弹性模型,将其周围流体视为非牛顿和非定常,可以使模拟更加真实。在严重程度高达50%的狭窄中,红细胞受到轻微损害,而在严重程度为75%的狭窄中观察到溶血。通过改善动脉粥样硬化,弹性模量从500 k Pa提高到2 MPa,在60 bpm脉率和狭窄程度75%下,剪切应力最大值增长65%。与刚性和弹性动脉壁相比,动脉壁的超弹性模型导致较低的轴向速度、较低的血压、较低的剪切应力和较高的径向位移。 | Majid SIAVASHI Ava BINA Mojtaba SAYADNEJAD Borhan BEIGZADEH | 2024 | Journal of Central South University2024，31，1： | 0 |
| 9 | Adaptation Decision Support: An Application of System Dynamics Modeling in Coastal Communities显示文摘This research develops and applies a system dynamics(SD) model for the strategic evaluation of environmental adaptation options for coastal communities. The article defines and estimates asset-based measures for community vulnerability, resilience, and adaptive capacity with respect to the environmental, economic, social, and cultural pillars of the coastal community under threat. The SD model simulates the annual multidimensional dynamic impacts of severe coastal storms and storm surges on the community pillars under alternative adaptation strategies.The calculation of the quantitative measures provides valuable information for decision makers for evaluating the alternative strategies. The adaptation strategies are designed model results illustrated for the specific context of the coastal community of Charlottetown, Prince Edward Island, Canada. The dynamic trend of the measures and model sensitivity analyses for Charlottetown—facing increased frequency of severe storms, storm surges, and sea-level rise—provide impetus for enhanced community strategic planning for the changing coastal environment.This research is presented as part of the International Community-University Research Alliance C-Change project ‘‘Managing Adaptation to Environmental Change in Coastal Communities: Canada and the Caribbean'' sponsored by the Social Science and Humanities Research Council of Canada and the International Development Resource Centre. | Daniel Lane Shima Beigzadeh Richard Moll | 2017 | International Journal of Disaster Risk Science2017，8，4： | 0 |
