Objective This study is to examine the influence of familiarity on energy intake, eating behavior, and concentration of the plasma gut hormones in lean and overweight young male subjects. Methods Twenty-eight lean and twenty-eight overweight participants were recruited. Their food consumption was documented and analyzed when they had a test meal while they were paired with friends or strangers at the same weight stature. Their eating behavior was recorded with cameras hidden in the carton, and postprandial plasma gut hormone concentration were measured. Results Compared with overweight strangers（OS）, overweight friends（OF） had increased food consumption, prolonged and decreased number of chews per 10 g food. Compared with OS, postprandial plasma concentration of cholecystokinin-8 was significantly lower in OF group at 30, 60, and 90 min, whereas the concentration of glucagon-like peptide 1 was significantly lower at 60 and 90 min. Plasma ghrelin concentration was significantly higher in the OF group than that in the OS group at 90 and 120 min. No significant differences in gut hormone concentration were observed between lean strangers（LS） and lean friends（LF） groups at all time points. Conclusion Familiarity plays an important role in increasing energy intake and in changing of postprandial gut hormone concentration in overweight individuals.

Because of the important role of the absorption heat pump in low-grade thermal energy utilization, this paper extends it to micro domain and performs a finite-time thermodynamic modelling for a three-heat-reservoir (THR) thermal Brownian heat pump with heat transfer effect by using an equivalent combined cycle method, which was applied for macro endoreversible THR heat pumps. The working principle and energy transformation rule are studied, and the coefficient of performance (COP) and heating load are derived. With a fixed overall thermal conductance of three heat exchangers, the maximal heating load is determined by optimizing thermal conductance distributions among three heat exchangers and barrier height, and the optimal working temperatures are also obtained. The impact of external heat transfer is elucidated to show the difference between this model and a non-equilibrium thermodynamic one. Results indicate that external heat transfer determines the energy transformation directly, and performance characteristics are closer to reality when external heat transfer is considered. The heating load has a maximal value about thermal conductance allocation ratios. About half the overall heat exchanger inventory needs to be assigned to the heat exchanger of the heating space for maximal heating load. When the cycle is with only heat transfer effect, the net particle numbers are zero, and the cycle fails to pump heat. The research results are expected to offer an idea for thermodynamic optimization and design of micro THR thermal Brownian heat pump devices.

Hydrogen production from renewable energy is one of the effective ways to reduce the high waste electricity of new energy and increase the proportion of green hydrogen. The multi-alkaline electrolyzers optimization operation strategy is proposed considering flexible electric loads and hydrogen loads in response to the optimization operation of large-scale new energy hydrogen production systems and high abandonment of electricity. Firstly, after considering the demand for electricity and hydrogen loads on the user side, transferable electric loads and hydrogen load models are established based on the transferable characteristics of electricity and hydrogen. Secondly, the multi-stack electrolyzer optimization operation strategy is proposed, considering the operating characteristics of a single electrolytic cell and electrolytic efficiency. Satisfying system operation constraints and optimizing the operating model to minimize economic cost is established and solved using the Yalmip toolbox and Cplex. The calculation results show that the participation of transferable loads can promote wind power consumption, reduce system electricity consumption, and improve the system economy. Compared with the multi-stack electrolyzer rotation strategy, the strategy proposed in this article effectively reduces the start and stop times of the electrolyzer, stabilizes the standard deviation of electrolysis cell power fluctuation within 0.27, improves the service life of electrolyzer arrays and increases the overall electrolysis efficiency to about 57%. © 2025 Power System Technology Press.

目的研究从生命早期至成年仔鼠摄入不同剂量反式脂肪酸(TFA)对肝的影响。方法成年昆明SPF级小鼠雄性15只,雌性30只,根据体重将雌雄各自随机分成对照组、低剂量TFA组(4%占供能比)和高剂量TFA(8%占供能比),并给予相应剂量饲料。2周后按照雄雌比1∶2进行合笼,得到仔鼠。仔鼠断乳后给予与母鼠相同剂量的TFA饲料,24周时随机抽取每组10只仔鼠断头处死后取肝组织,测定脏器系数,肝组织中超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活性,谷胱甘肽(GSH)的含量,丙二醛(MDA)的含量,并观察肝组织病理学变化。结果高剂量TFA组仔鼠肝脏器系数增加,组织内SOD和CAT活性降低,GSH含量降低,MDA含量增加,与对照组比较,差异均有统计学意义(P<0. 05)。肝组织病理学结果显示低剂量TFA组和高剂量TFA组均有一定空泡变性和脂滴的出现,但高剂量TFA组上述现象更为明显。结论从生命早期到成年仔鼠摄入高剂量反式脂肪酸通过诱导脂质过氧化,引起氧化应激,影响肝组织结构,导致肝损伤。
