2023年夏季,我国整体表现为高温少雨的特征,旱涝分布不均。夏季台风虽然生成和登陆个数均较常年偏少,但破坏力极强。华北、西北等地阶段性高温事件异常突出,但长江流域的高温干旱强度明显弱于2022年同期。从预测效果来看,2023年汛期预测较好把握了我国北方主雨带特征,对松花江流域、嫩江流域、海河流域可能出现的较重汛情做出了准确的预测预警。对夏季热带气旋的生成个数、主要路径、影响区域等的预测与实况较为相符。对夏季全国大部地区气温偏高的特征预测与实况一致,并明确指出,长江流域发生类似2022年夏季大范围持续性高温干旱事件的可能性低。汛期预测的不足之处主要在于对华南等地的降水预测与实况出现较大偏差,对华北、黄淮等地的高温过程极端性估计不足。针对2023年汛期降水的先兆信号及其预报性能进行了回顾和评估,无论是年代际尺度还是年际尺度外强迫信号,均对我国北方主雨带有较好的指示意义。同时,几乎所有先兆信号都对华南降水给出了一致的错误信息,是导致华南降水预报失败的主要原因。

民歌与调解的“联姻”方式是榕江县法院结合本地区民族特色所形成的纠纷化解方式之一。“民歌调解”在当地得以有效适用的主要原因有两个方面:一是民歌承载当地共同遵循的社会规范,并将其予以通俗化与柔性化;二是受众仍受“息讼”传统的影响且集体主义观浓厚。“民歌调解”亦存在适用困境,主要表现为规范供给不足、重视秩序维护的调解倾向以及专门的调解人才难以为继等。为有效推进民族地区法治建设及做好民族工作,应立足于民族地区特有丰富的本土情法资源,完善相关实体与程序规范,坚持以人为本,明确调解的价值中立定位,补充并强化人才可持续补给机制,借此推动多元共治下少数民族基层治理模式日趋完善。

开关磁阻电机(SRM)使用传统的转矩分配函数控制时由于转矩分配函数的开关角度恒定,使其在换相阶段出现较为明显的转矩脉动和较高的峰值电流现象。针对这一现象,提出实时调节开关角度的指数型转矩分配函数的控制方法来降低转矩脉动与相峰值电流。与传统的转矩分配控制进行比较分析,所提算法能够在不同电机转速下抑制转矩脉动和降低SRM定子绕组换相峰值电流,在中低速情况下,实时优化转矩分配函数开关角与重叠角,提高了SRM的运行效率。以一台2.2 kW的12/8开关磁阻电机作为控制对象,建立控制系统仿真模型,通过仿真和实验验证了所提算法的有效性。

在利用位置指纹进行实时室内定位时,由于多径效应、信号闭塞或无线AP本身不稳定,而影响最终的定位效果。对此,提出了一种基于子区域切分结合麻雀算法(Sparrow Search Algorithm,SSA)优化XGBoost的室内定位方法。离线训练阶段,利用改进的FCM(Fuzzy C-means)算法和区域相关系数指标将待定位区域划分为多个子域,通过AP优化为每个子域选择最优AP集合。针对XGBoost算法性能易受到初始参数问题影响,利用麻雀算法对XGBoost初始参数寻优得到相对较优的参数,并分别为各个子区域构建SSA-XGBoost定位模型。在线定位阶段,目标点通过匹配子区域的聚类中心得到所属子区域,最终利用该子区域的定位模型预测目标点的位置。与其他定位算法相比,所提算法平均误差分别减少14.7%、22.4%、37.1%,证明所提方法在实际环境中较其他算法具有更好的定位效果。

The Ru complexes have garnered a great deal of attention for antitumor phototherapy; however, achieving efficient cellular uptake and tumor-specific activation represents a major challenge. Herein, we synthesize a hypoxia-activated Ru complex(RuANM) and construct it into supramolecular polymers(PolyRuANM) through high binding affinity interaction. The amphiphilic supramolecular polymers possess self-assembly, resulting in the formation of diverse nanostructures exhibiting a range of morphologies by simply adjusting the host-guest ratio. As the polymer nanostructure size and morphology have been optimized, PolyRuANM prevents premature drug leakage and accumulates rapidly in the tumor cells. In the tumor hypoxia microenvironment, the polymer undergoes selective activation and disintegration, leading to the unlock of Ru ***, the subsequent application of red light irradiation exacerbates the hypoxia and potentiates the liberation of the Ru complexes. This polymer design concept provides some novel insights into on-demand drug delivery and smart chemophotodynamic therapy.
