RNA-seq for comparative transcript profiling in leaves of strawberry seedlings under salinity stress
Zhang Rui,Du Qiuli,Zhao Wenzhe,Yang Long,Li Dong-mei,Chen Xiude,Xiao Wei,Fu Xiling,Yang Chao,Li Ling 한국식물생명공학회 2023 Plant biotechnology reports Vol.17 No.1
As a major economic crop, strawberry (Fragaria × ananassa Duch.) has been widely planted in the world because of their adaptability and high economic efficiency. In the process of strawberry production, the traditional techniques of furrow irrigation, irrigating irrigation and water and fertilizer management are still relatively common, resulting in secondary salinization of the soil and an imbalance of nutrient ratio, resulting in a decrease in strawberry yield and quality. A total of 2334, 2718 differentially expressed genes (DEGs) were identified in the 3-day, 6-day salt-treated leaf tissues compared with the controls, respectively. Based on the analysis of DEG function annotation and enrichment, a pattern of strawberry leaves response to NaCl stress was proposed. The processes related to plant hormone signal and lipid metabolism pathway were noted in the response of strawberry leaves to NaCl. Our transcriptome data provides valuable insights into genes involved in the growing process of strawberry seedlings under salt stress, and may help in developing seedlings with enhanced responses to salt stress in the years to come.

Composite components damage tracking and dynamic structural behaviour with AI algorithm
Z.Y. Chen,Sheng-Hsiang Peng,Yahui Meng,Ruei-Yuan Wang,Qiuli Fu,Timothy Chen 국제구조공학회 2022 Steel and Composite Structures, An International J Vol.42 No.2
This study discusses a hypothetical method for tracking the propagation damage of Carbon Reinforced Fiber Plastic (CRFP) components underneath vibration fatigue. The High Cycle Fatigue (HCF) behavior of composite materials was generally not as severe as this of admixture alloys. Each fissure initiation in metal alloys may quickly lead to the opposite. The HCF behavior of composite materials is usually an extended state of continuous degradation between resin and fibers. The increase is that any layer-to-layer contact conditions during delamination opening will cause a dynamic complex response, which may be non-linear and dependent on temperature. Usually resulted from major deformations, it could be properly surveyed by a non-contact investigation system. Here, this article discusses the scanning laser application of that vibrometer to track the propagation damage of CRFP components underneath fatigue vibration loading. Thus, the study purpose is to demonstrate that the investigation method can implement systematically a series of hypothetical means and dynamic characteristics. The application of the relaxation method based on numerical simulation in the Artificial Intelligence (AI) Evolved Bat (EB) strategy to reduce the dynamic response is proved by numerical simulation. Thermal imaging cameras are also measurement parts of the chain and provide information in qualitative about the temperature location of the evolution and hot spots of damage.

Stochastic intelligent GA controller design for active TMD shear building
Z.Y. Chen,Sheng-Hsiang Peng,Ruei-Yuan Wang,Yahui Meng,Qiuli Fu,Timothy Chen 국제구조공학회 2022 Structural Engineering and Mechanics, An Int'l Jou Vol.81 No.1
The problem of optimal stochastic GA control of the system with uncertain parameters and unsure noise covariates is studied. First, without knowing the explicit form of the dynamic system, the open-loop determinism problem with path optimization is solved. Next, Gaussian linear quadratic controllers (LQG) are designed for linear systems that depend on the nominal path. A robust genetic neural network (NN) fuzzy controller is synthesized, which consists of a Kalman filter and an optimal controller to assure the asymptotic stability of the discrete control system. A simulation is performed to prove the suitability and performance of the recommended algorithm. The results indicated that the recommended method is a feasible method to improve the performance of active tuned mass damper (ATMD) shear buildings under random earthquake disturbances.

Smart structural control and analysis for earthquake excited building with evolutionary design
Z.Y. Chen,Ruei-yuan Wang,Yahui Meng,Qiuli Fu,Timothy Chen 국제구조공학회 2021 Structural Engineering and Mechanics, An Int'l Jou Vol.79 No.2
In recent years, with the maximization of control design and efficiency, and the improvement of economy and energy efficiency, building technology and control in the theory have attracted the attention of lots researchers. By trying various control theorems, many numerical methods have been investigated in the literature to achieve this target, but all these numerical methods are difficult to work out the problem correctly. This paper puts forward a potentially feasible evolutionary bat algorithm (EB) method for active control of earthquake-induced vibration in building structures. Based disturbance observer based control and S surface combined with the robust adaptive control scheme for solving optimization problems proposed, an important contribution in the control law is what the configuration control in the present study should not require known uncertainty limits and the disturbance is eliminated. A simulation case study was proposed to illustrate the possibility of implementing an apparent learning method in ANN to effectively control structural vibration under the influence of systematic motion under earthquake citations. The proposed learning numerical methods does not need to develop a mathematical model of structural dynamics or train another neural network to approximate the actual structural response to be performed.
