基于严格解方法,研究了一维排斥相互作用单自旋翻转费米气体的基态和淬火动力学性质.借助Bethe波函数,基态和不同本征态之间的单体关联函数和两体关联函数可以表示为简单函数之和,这一简洁形式可以极大地降低计算难度.系统初始状态为无相互作用的基态,当迅速把相互作用强度调节为有限大时,动量分布和关联函数出现周期性的振荡行为;当相互作用调节为比较弱时,振荡周期性好且振荡幅度小,系统可以用二能级模型近似;当相互作用调为非常强时,振荡周期性变差且振荡幅度大,但是依然存在主周期.此时整体偏离初态较远,但是在时间为mL^(2)/(2πh)时系统非常接近初态.

为了研究四溴双酚A(tetrabromobis-phenol A,TBBPA)对海洋桡足类的急性毒性和氧化胁迫效应,以太平洋真宽水蚤为受试生物,测定了TBBPA对其96 h急性毒性和对其体内抗氧化防御系统的影响。结果表明,TBBPA对太平洋真宽水蚤的96 h半数致死浓度(96 h-LC50)为178μg·L^(-1),95%可信区间为91~306μg·L^(-1),表现为极毒。亚致死浓度下,TBBPA能够不同程度影响太平洋真宽水蚤的抗氧化防御酶活力以及非酶物质含量。其中SOD和GST活性的变化趋势较为一致,暴露初期SOD和GST活性显著上升(P<0.05),随暴露时间延长酶活性有所下降,最终趋向对照组水平;GPx活性水平始终维持在对照组以上并且差异显著(P<0.05);暴露初期,GSH含量受轻微氧化压力而轻微升高,暴露48 h后GSH含量急剧下降并显著低于对照组(P<0.05)。太平洋真宽水蚤体内SOD、GST、GPx活性和GSH含量对TBBPA暴露均十分敏感,能够为海洋环境的TBBPA监测提供生化指标参考。

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.
