为了提升电力系统中碳流预测的精度,文中对传统统计学观点下的一次能源转换计算思路进行了改进,基于电网潮流计算时碳流的依赖关系,设计了碳流预测模型。该模型以电网的安全运行和经济性为约束条件,引入电网分布特性机理和深度学习理论求解电网最优的碳流排放状态。在求解该模型时,对传统的强化学习Q-Learning算法进行了改进,通过结合瞬时差分的多步迭代,设计了一种基于概率分布选择动作的Q(λ)算法。该方法确保了模型在迭代过程中较高Q值动作的选择概率,提升了模型求解时的收敛速度,保证了网络寻优的鲁棒性。为了评估碳流预测模型的有效性,基于IEEE9节点网络设计了仿真实验。仿真结果表明,改进后的深度学习网络在预测碳流排放时其MAPE、NMSE分别提升了2.85%和6.06%。

Real-world study(RWS)gained prominence starting with a significant investigation on ramipril’s impact on hypertension in 1993(1).A key advancement for the Food and Drug Administration(FDA)occurred with the enactment of the 21st Century Cures Act in 2016,emphasizing RWS(2).The FDA’s Real-world Evidence Program establishes real-world data(RWD)as“data relating to patient health status and/or the delivery of health care routinely collected from a variety of sources”,while real-world evidence(RWE)is“clinical evidence about the usage and potential benefits or risks of a medical product derived from analysis of RWD”(3).The proliferation of big data,electronic medical records(EMR),electronic health records(EHR),and medical claims data offers vast information resources facilitating *** access to RWD allows for worldwide monitoring of the impacts of various public health initiatives like vaccination *** randomized clinical trials(RCTs)traditionally gauge vaccine efficacy and shortterm safety,RWS can assess vaccine performance and safety across larger,more diverse populations and are adept at identifying rare events not easily discernible in RCTs due to their infrequency.

Advances in Breast Cancer Research 2022年第1期11卷 1-30页

作者： Qiongge Wang Jiuli Hu Junwei Liang lanfang liu Shuoyang Xiao Rui Wang Chanchan Hu Hospital of Chengde Medical College Chengde China

Objective: Breast Cancer (BC) is characterized by high complexity and heterogeneity, and microRNA (miRNA) is bound up with the occurrence and development of BC. In this study, we evaluated the prognostic value of miRNA in BC. Background: Breast ductal and lobular cancers are the most common types of Breast Carcinomas (BC) and indicate the high complexity heterogeneity in this disease. Each BC patient has unique morphological and molecular features. MicroRNAs (miRNAs) play a critical role in human oncogenesis, progression, and prognosis. Our study aimed to identify potential prognostic biomarkers of breast ductal and lobular cancers to predict the overall survival outcome. Methods: All analyzed miRNA sequencing and clinical data were obtained from the Genomic Data Commons Data Porta. edgeR package in R software was used to analyze the differential miRNA expression profiles. Complete survival information and differentially expressed miRNA expression were obtained and the Caret package was used for random division of the samples along with their profiles into two groups (training group and test group).
