Political Cycles, Electricity Policy, and Mexico's Economy
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Gaoya dianqi负荷建模在电力系统的运行和控制方面扮演着至关重要的角色，找到一种有效、可靠的负荷建模参数辨识优化方法具有重要的实际意义。文中利用支持向量机（support vector machine，SVM）方法对电力系统负荷进行建模研究，通过高斯径向基函数作为核函数，选择支持向量机模型的基础结构。在模型辨识过程中，以PMU实测电流、电压以及相角数据作为输入变量，以有功功率和无功功率作为输出变量。基于测量的负荷建模方法使用留一交叉验证法（leave-one-out cross-validation，LOOCV ...

Veterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

Gaoya dianqi, 2016 文中针对大规模电动汽车（EVs）接入微电网的分布式能源（DER）出力优化进行了研究。在（EVs）无序充电模型的基础上,提出了基于峰谷负荷的分段电价模型,考虑行驶需求时间共同影响,建立了EVs接入微电网的完全响应行为模型。对负荷进行分类建模,提出基于响应权重的常规负荷电价响应模型,并建立了基于经济成本权重的综合效益优化模型。在典型微电网中,通过改进遗传算法,在不同调度控制策略下计算得到系统的优化出力结果。通过对比不同模型下的出力结果,验证所提模型的正确性和有效性。
