Published: March 2024

Las emociones que se producen en los procesos de enseñanza-aprendizaje en ciencias experimentales presentan cuestiones todavía por resolver. En este artículo, hemos utilizado un método paramétrico que usa el reconocimiento facial y permite identificar las emociones en tiempo real y vincularlas con acciones educativas concretas. Se diseñó una actividad para hacer aflorar las emociones en un proceso en el que las conjeturas iniciales colisionaban con los hechos. El análisis muestra cambios muy intensos en las expresiones emocionales de los estudiantes y la existencia de tres tipos de comportamiento frente a esta disonancia entre previsiones y observación: 1) sorpresa; 2) disgusto; y 3) solapamiento de sorpresa y disgusto. Parece especialmente interesante considerar qué emociones específicas genera cada situación de aprendizaje para cada individuo.

Prospects for Stimulating Autoimmunity and Developing New T Cells in Cancer Treatment
Authors: Mei Shiqi , Ti Haowei 
Published: March 2024

Any adverse problem or weakening of the body's immunity, such as HIV infection, long-term physical and mental stress, nutritional deficiencies, chemotherapy or major surgery, will make cells prone to cancer. The body's immune system also deteriorates with age, which may help understand how people's risk of developing cancer increases significantly as they age. If the body's immune system is no longer strong enough to completely destroy cancer cells, then we move from "eliminating" cancer to "balancing."The immune system is the body's protective network, consisting of immune cells, immune organs, and immune substances. It fights against foreign pathogens and mutated cells in the body to maintain the health of the human body's internal environment.
Strictly speaking, patients with better physical conditions have higher and more powerful T cells, and the more T cells awakened by immune drugs, they are relatively more effective in eliminating tumor cells. Currently, T cell-based immunotherapy includes CAR-T therapy, TCR-T therapy, TILs therapy, and CTL therapy.
Short-circuit Current-based Parametrically Identification for Doubly Fed Induction Generator
Authors: Zhu Yong , Tao Yongwei , Li Zequn 
Published: March 2024

Recently, deep learning has provided a new opportunity to achieve high precision and real-time parameter identification of the doubly-fed induction generator (DFIG) in the event of short-circuit fault. However, deep learning algorithms based on data training are facing the challenge of relying on a large amount of training data and poor generalization performance. In order to improve these shortcomings, we embed the forward calculation model of three-phase short-circuit current (SCC) into the neural network, and propose an unsupervised neural network which can realize high-precision parameter identification. The network only needs to convert the short circuit current curve into a two-dimensional gray level map to complete the precise training of the network without real labels, which effectively improves the fitting ability of the network for inverse problems. The simulation results show that the proposed method can achieve high precision identification of DFIG parameters both within and outside the domain, and verify the high precision identification and generalization ability of unsupervised networks.

Published: March 2024

The aerosol vertical distribution in the boundary layer is heavily influenced by the boundary layer thermal structure. This paper studied on marine boundary layer (MBL) aerosol and its structure by using satellite lidar measurements. The lidar methodology was improved and applied to the 3-year satellite MBL aerosol observations over Oceans, and a new global ocean dataset was built. The global MBL structure were examined and discussed with the new dataset. Results showed that the BLH generally increases and MLH generally decreases when away from the coast. Further analyze shows that the MBL tends to be more well-mixed with lower BLH, and the aerosol loading shows weaker relationships with U10m under overcast conditions than partly cloudy conditions. This study demonstrated that satellite lidar measurements have the great potential in evaluating and constraining both modeled MBL aerosol optical properties and modeled MBL structure.

Authors: Liu Han , Liu Zhen , Wang Suyue 
Published: March 2024

Recently, the multi-frequency HF radar has attracted much attention. However, only a few works focus on the method of obtaining wave information directly. In this work, a wave spectrum inversion method for multi-frequency HF radar in complex sea conditions is proposed. This method considers the swell component in the ocean, and uses multiple HF radars of different frequencies to obtain the echo Doppler spectra from complex sea conditions with wind and swell coexisting. And then the wave spectrum is derived from the high-energy outer second-order spectra and the corresponding first-order peak of the Doppler spectra. In addition, the proposed method is applied to the simulated sea echo data and the result indicates that the method is effective.

Double Restriction of Bismuth Nanoparticles by Carbon Matrixes for Ultralong−lifespan Sodium Storage
Authors: Huang Fuchao , Liu Zheng , Cao Ke , Fan Zhuangjun 
Published: March 2024

Alloying-type bismuth (Bi) anodes show a high theoretical capacity for sodium-ion batteries (SIB), yet their huge volume expansion and electrode pulverization resulted in poor electrochemical stability. Herein, we proposed a feasible strategy for the preparation of carbon/Bi composite material in which the Bi nanoparticles are uniformly dispersed in the double-layered carbon matrix. Benefiting from the synergistic confinement of the external coating of graphene and the internal layer of MOF-derived carbon, the volumetric expansion and large chemo-mechanical stress of Bi nanoparticles are effectively buffered. Therefore, the GAB@GO-800 anode exhibits a dramatically reversible capacity of 328 mA h g−1 at 0.1 A g−1, exceptional rate capability (299 mA h g−1 at 5 A g−1), and ultrahigh stability of 255 mA h g−1 at 2 A g−1 over 2000 cycles. Such hybrid carbon confinemental strategy via a combination of graphene coating and MOF-derived carbon is expected to be a promising method for the alloying-type anodes of SIBs.
Modification 1T-MoS2 with surface ions towards electrocatalytic hydrogen evolution reaction

Published: March 2024

Molybdenum disulfide (MoS2) is considered as a thriving and cost-efficient electrocatalyst for hydrogen evolution reaction (HER). Unfortunately, the semiconductor phase of 2H-MoS2 itself has a conservative electronic intrinsic transport rate and the restricted active sites to edge regions, leading to unsatisfactory electrocatalytic performance of HER. Here, we have fabricated highly conductive metal phase 1T-MoS2 nanosheets by a hydrothermal method and introduced a series of transition metal ions on their surfaces by an in-situ reduction strategy to achieve MoS2 surface modification. It was found that the metals Ni and Co not only enhanced the intrinsic conductivity of 1T-MoS2, but also significantly increased the number of active sites in the catalyst, which resulted in the catalyst exhibiting excellent HER activity. Ni@1T-MoS2 exhibits fast reaction kinetics (86 mV·dec-1), good mechanical stability (~28 h) and low energy consumption in 1.0 M KOH medium, as well as an over-potential of only 187 mV at 50 mA·cm-2.
Research on Singularity in Calculation of Induced Electric Field in Pointed Conductors
Authors: Li Kejie , Sun Dian 
Published: March 2024

In the electric field environment of thunderstorm, the tip of a grounded object at a high place is more likely to produce corona discharge and finally cause lightning flash. Therefore, the study of the surface electric field of the grounded object tip in the electric field environment has important theoretical value and practical significance for the analysis of the characteristics of the head-on discharge. Due to the strong singularity of the tip structure, the traditional numerical analysis method cannot accurately calculate its surface electric field. Therefore, the traditional literature usually chamfers the conductor tip, but in lightning physics, researchers are most concerned about the maximum field strength in the local area. In order to study the electric field distribution on the tip conductor surface, a semi-analytical boundary element method is proposed to calculate the tip structure directly. Firstly, the analytical formula of the electric field on the tip conductor surface and the boundary element semi-analytical common method are derived, and the tip conductor model is established to calculate the tip electric field excited by the external electric field using the analytical solution and the semi-analytical method. The correctness of the semi-analytical method is verified by calculating the L2 loss function of the two, and the influence of the tip angle on the semi-analytical calculation results is studied. The results show that for the three-dimensional cone model, the L2 loss function is 10-5, which meets the calculation accuracy. The special treatment of the semi-analytical method at the strong singular integral makes the calculation accuracy much higher than that of the Gaussian integral, where the L2 loss function is greatly reduced. Further, based on the change of tip angle, as the conductor tip becomes sharper, the greater the electric field distortion is, and the greater the L2 loss function is. The research results provide a method reference for the calculation of the electric field on the tip conductor surface.

Authors: Zhao Chenxu , Ying Zongquan , Du Chengbin , Yang Shuai 
Published: March 2024

Pull-out tests were conducted to investigate the effects of corrosion of the both longitudinal bar on the bond-slip behaviour of reinforced concrete specimens. The main experimental variables include concrete strength (26.7 MPa, 37.7 MPa, 45.2 MPa) and expected corrosion rate (0%, 4%, 8%, 12%), with a total of 36 specimens fabricated. The results show that the relative bonding strength of specimens under different concrete strengths gradually decreases with increasing corrosion rate, but the higher the concrete strength is, the faster its degradation rate. Based on the experimental results of this work and the achievements of other scholars, a modified relative bonding strength degradation model is presented by accounting for the influence coefficient of concrete strength.

Published: March 2024

In order to improve the stress concentration in concrete at steel nodes caused by zero thickness springs, the improved Spring2 nonlinear spring model from ABAQUS is used to simulate the bond-slip behavior between non-uniformly corroded reinforcement and concrete. Based on the collected test results with different stirrup spacing, fitting the influence coefficients of bond stress under stirrup corrosion. With the combination of a non-uniformly corroded rebar distribution model, the refined numerical simulation of the drawing process of reinforced concrete specimens was carried out using ABAQUS. The study shows that the improved nonlinear spring model is better than the zero thickness spring model in terms of computational accuracy and efficiency. The stirrup correction coefficient is approximately linear with the stirrup spacing; the bond-slip relationship considering the effect of stirrup spacing, has a better consistency with the relevant tests in the simulation of the pullout test. Weibull distribution for the fitting of non-uniform corrosion of reinforcement is more reasonable than Gumbel distribution.
