Aiming at the study of the predetermined trajectory control problem of the lower extremity exoskeleton, the kinematics and dynamics model of the two-degree-of-freedom mechanical leg was constructed. A transformation relationship between the load force and the expansion of the asymmetric hydraulic cylinder, and the rotation torque and motion angle of the exoskeleton was proposed, and the precise trajectory control of the exoskeleton was further realized by using the backstepping method. Firstly, the kinematics model of the two-degree-of-freedom lower extremity exoskeleton system was established by using the Denavit-Hartenberg (D-H) method. The relationship between the joint velocity of the exoskeleton end-effector was studied, and the mathematical model of the exoskeleton dynamics was derived by using the Lagrange dynamic equation. Then, by controlling the load force of the hydraulic cylinder, the corresponding torque was provided for the movement of the mechanical leg, and the motion posture of the lower limb exoskeleton was controlled. Secondly, aiming at the high precision requirement of the lower extremity exoskeleton movement, the state space equation of the valve-controlled asymmetric cylinder system combined with the whole lower extremity exoskeleton dynamics system was established by using the backstepping control theory. The hydraulic servo system of the lower extremity exoskeleton was controlled, so as to control the lower extremity exoskeleton to carry out the predetermined trajectory movement. Finally, through the joint simulation of AMESim software and Visual Studio software, the accuracy of PID control and backstepping control was compared and analyzed. The research results show that the maximum error of the backstepping control was 2 ° for the predetermined trajectory control of the lower extremity exoskeleton. Comparing with the traditional PID control, the error is reduced by 67 %. The designed backstepping controller had good control accuracy for lower limb exoskeleton. [ABSTRACT FROM AUTHOR]

Heat stress has been one of the most important factors in the dairy industry against global warming in recent years. The milk performance of dairy cows can be confined to long-term heat stress. The purpose of this experiment was to investigate the effects of spoiler fans cooling on milk performance and immune function in dairy cows. Two cowsheds were used with the same building structure and system. The spoiler fan were installed, while the control cowshed was uninstalled any fans. The lactation performance (including milk yield, 4% fat-corrected milk, milk protein rate, milk fat rate and lactose rate) and lymphocyte apoptosis rate were detected in different experimental periods; Meanwhile, blood biochemical parameters and their mRNA expression were also investigated, including four kinds of cytokines (Interleukin-1 (IL-1), Interleukin-2 (IL-2), Interleukin-6 (IL-12), and Interleukin-12 (IL-12)), six kinds of apoptotic factors (BAK, Mcl-1, Bax, Bcl-2, Bcl-xl, and P53), and three kinds of immunoglobulins (Immunoglobulin A (Ig A), Immunoglobulin G (IgG), Immunoglobulin M (IgM)). Besides, Spearman correlation analysis was carried out between milk performance or immune parameters and equivalent temperature index for cattle (ETIC). Approximately 200 Holstein lactating dairy cows were kept in each cowshed. The whole experiment period was 42 days from June to August, including four stages: initial (0 d), early (1-14 d), middle (15-28 d) and late stage (29-42 d). The results showed that: 1) The installed fans improved the cowshed environment, where the ETIC was reduced by 3.52 ℃ during the entire period, compared with the control cowshed. Cows in the control shed were in the moderate heat stress, while cows in the fan-installed shed were in the mild heat stress. Thus, the fans significantly alleviated the heat stress in cows. 2) Installation of fans improved the production performance of dairy cows exposure to heat stress. The milk yield, 4% fat-corrected milk, and milk fat increased in the fan-installed shed during the middle and late periods of experiments, compared with the control shed (P<0.05). Particularly, the 4% fat-corrected milk increased by 39.1% during the middle period and by 35.2% during the late period, respectively. The milk fat percentage in the fan-installed shed also showed an increase of 22.5% and 20.8%, respectively (P<0.05). 3) Installed fans improved the immune function of dairy cows under heat stress. Blood lymphocyte counts during the middle and late periods were greater in the fan-installed shed than those in the control group (P<0.05), and their early apoptosis rates of lymphocytes decreased (P<0.05). Moreover, there was a reduction in the mRNA expression of pro-apoptotic factor Bax in lymphocytes and its serum level (P<0.05) during the late period. An increase was found in the mRNA levels of anti-apoptotic factor Bcl-xl in lymphocytes and its serum level was demonstrated (P<0.05) during the middle and late periods. Besides, the installed fans increased the serum levels of IL-12 and IgG (P<0.05). 4) The correlation analysis showed that the milk protein rate and the lymphocyte count demonstrated a negative correlation with ETIC (P<0.05), and the BAK mRNA expression in lymphocyte and serum IL-6 level exhibited a positive correlation with ETIC (P<0.05). In conclusion, the spoiler fans in the shed can be expected to effectively relieve the heat stress in cows in summer, thus promoting the thermal environment and blood biochemical indicators in cows for better production performance and immune function.

OBJECTIVE: To probe into the efficacy and safety of brivudine monotherapy and foscarnet sodium combined with famciclovir in the treatment of patients with herpes zoster. METHODS: Retrospective study was conducted. A total of 200 patients with herpes zoster treated with oral brivudine tablets (brovudine group, 100 cases) or intravenous drip of foscarnet sodium and sodium chloride injection combined with oral famciclovir tablets (foscarnet sodium combined with famciclovir group, 100 cases) for more than 1 week were extracted from the dermatology department of the First Affiliated Hospital of Harbin Medical University from Jul. 2020 to Dec. 2021. General information of patients, the parameters of efficacy evaluation (such as stopping time of blister, scab time, removal time of scab and relief time of 50% pain), incidence of postherpetic neuralgia and adverse drug reactions were collected. The clinical efficacy and incidence of adverse drug reactions were compared between two groups. RESULTS: There were no significant differences in the stopping time of blister, time to scab and removal time of scab between two groups (P>0. 05). The relief time of 50% pain in brovudine group was significantly shorter than that in foscarnet sodium combined with famciclovir group, and incidence of postherpetic neuralgia was significantly lower than that in the foscarnet sodium combined with famciclovir group, with statistically significant differences ( P < 0. 05). The total effective rate was 86% (86 / 100) in the brovudine group and 82% (82 / 100) in the foscarnet sodium combined with famciclovir group, with no statistically significant difference (P>0. 05). The incidence of adverse drug reactions in brovudine group was significantly lower than that in foscarnet sodium combined with famciclovir group, the difference was statistically significant (P<0. 05). CONCLUSIONS: The efficacy of oral brivudine tablets and intravenous drip of foscarnet sodium and sodium chloride injection combined with oral famciclovir tablets is comparable in the treatment of herpes zoster, yet bromovudine is more effective in relieving acute phase pain and post-herpetic neuralgia, and oral administration is more convenient and safer.

From the perspective of constructivism teaching，preconceptions play an important role and have attracted the continuous attention of the international science education community as the construction basis of new knowledge. The research on the preconceptions of work and mechanical energy is reviewed and summarized in three main areas，including preconceptions，evaluation tools and teaching strategies of concept transformation. It is found that students’understanding of preconceptions of work and mechanical energy has commonly existing difficulties among on the basic definition，size， positive and negative（direction）and variation. For effective measurement of these preconceptions for work and energy，researchers developed a variety of assessment tools such as energy and momentum concept survey，energy concept inventory，energy concept assessment. For students’preconcepts，there are mainly two constructivist teaching strategies with emphasis on cognitive conflict and scaffolding to promote students’concept transformation. Through the systematic combing of the preconcepts of work and mechanical energy，it can provide references for in-depth research on this topic and other preconcepts，so as to bring beneficial enlightenment to the cultivation of physical concepts under the current emphasis of science literacy.

Aiming at the problem that the synchronous control accuracy of a new hydraulic fan coil car drive cylinder group was low, the synchronous control strategy of hydraulic cylinder group under load force disturbance was studied. A fuzzy PID controller based on particle swarm was proposed.Firstly, the mathematical model of single driving cylinder and the synchronous control system model of cylinder group were established. Secondly, particle swarm optimization（PSO） algorithm was used to optimize the quantization factor Ke, Kec and scale factor Ku of fuzzy controller iteratively, and then three control parameters of PID controller were adjusted. Then, the output displacement difference of two hydraulic cylinders was used as feedback signal, and the error compensator was introduced to form the state difference feedback. Finally, under the joint action of step excitation signal and constant load disturbance signal, the synchronous control of the drive cylinder group was simulated by Simulink, and the results were compared with traditional PID controller and fuzzy PID controller. The results show that compared with traditional PID controller and fuzzy PID controller, the synchronous system under PSO-fuzzy PID controller control runs stably, without overshoot, with only weak oscillation and short adjustment time, and the synchronization accuracy is high under the influence of step disturbance force. The driving cylinder group can move accurately, and it has strong adaptive ability. [ABSTRACT FROM AUTHOR]
