The optimal path algorithm of bus network considered multi-mode transferring(考虑多方式换乘的公交网络最优路径算法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2011
在传统的公交网络最优路径算法中,往往只考虑了原地换乘,这样就导致了部分出行路径的缺失.例如,在现实生活中,乘客常常可以通过步行或骑自行车到相邻站点再换乘公交车的方式来实现最优出行.通过对换乘方式的分析,描述了乘客出行的完整路径;根据公交线路的关联情况和公交站点的空间位置关系,抽象出了关键换乘点;并依据关键换乘点的定义对公交网络进行了变换,继而建立起公交网络通达矩阵;最后在此基础上计算出考虑多方式换乘的换乘次数最少、所需时间最短的公交出行路径,为乘客提供更灵活的出行选择.

Lipid Profile Alterations Across Coronary Heart Disease, Metabolic Syndrome, and Nephrotic Syndrome

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
CHD, MetS, and NS exhibit distinct dyslipidemia patterns. TC, TG, ApoB, ApoE, and sdLDL‐C are key markers for disease differentiation. This study found that elevated TC and sdLDL‐C were key pathogenic factors in CHD. In contrast, TG and ApoB played significant roles in the pathogenesis of MetS.

Matrine Attenuates Neurological Deficits and Neuroinflammation by Inhibiting the HMGB1/RAGE Axis and Ferroptosis in Intracerebral Hemorrhage Mice

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Intracerebral hemorrhage (ICH) is a life‐threatening stroke subtype that lacks effective drug therapy. In the context of ICH, neuroinflammation, and ferroptosis are key contributors to secondary brain injury. In this study, we assessed the neuroprotective effects of matrine (MAT) and its mechanism of action involving the HMGB1/RAGE axis in an ...

Synthesis of Core–Shell Te@Se Quantum Dots and Their Broadband Photodetector Performance in Low Concentration Electrolytes

open access: yesLaser &Photonics Reviews, EarlyView.
Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.
