New aesthetics of the city – design of cyclists traffic signs
Transport, 2005 In a number of towns and cities worldwide development programmes have been initiated to provide designated bike surfaces reserved for the movement of cyclists along city network.

Animal Models and Experimental Medicine, EarlyView.Phenylhydrazine (PHZ) induces hemolytic anemia characterized by increased erythrocyte destruction and ineffective erythropoiesis, leading to hepcidin suppression through disruption of the BMP/SMAD signaling pathway. Reduced hepcidin levels enhance intestinal iron absorption and hepatic iron accumulation, leading to hepatic iron overload.

Angewandte Chemie, EarlyView.1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...

Proceedings of the National Academy of Sciences, 1997 Uphill transport of one substrate (the driven substrate) can be coupled to the dissipation of an electrochemical potential gradient of another substrate (the driving substrate), to an exergonic chemical reaction, or to a photoreaction. In all cases, the driven substrate is taken up from a low concentration (or relatively low electrochemical potential ...

Competition and Cooperation between Shared Bicycles and Public Transit: A Case Study of Beijing
Sustainability, 2019 As an eco-friendly transportation mode, shared bicycles provide a new option for public transit users in urban areas. China’s bicycle-sharing market began flourishing in July 2016 and reached a plateau in 2017.

Angewandte Chemie, EarlyView.A photochemical platform enables β–β coupling of cyclopropyl silyl ethers with electron‐deficient alkenes. The resulting adducts serve as entry points into annulative and radical–polar crossover pathways, providing rapid access to fused, bridged, and spirocyclic architectures, including late‐stage scaffold diversification to diterpene‐like carbocyclic ...

Sustainability, 2019 Bicycle sharing services have played an active role in building a green travel system in China, but this trend has also caused problems, such as users arbitrarily stopping on the roads or the destruction of shared bicycles.

T‐Shaped Stibenium(III) Cation: Hydrostibination Without Sb─H Bond
Angewandte Chemie, EarlyView.A cationic, structurally constrained stibenium platform mediates anti‐Markovnikov hydrostibination of alkenes via element–ligand cooperativity (ELC), thereby bypassing the need for weak Sb─H bonds. ABSTRACT The hydrostibination of alkenes represents a largely underdeveloped transformation, owing to the intrinsic lability of the required Sb─H reagents ...

Advanced ScienceThe present paper reports a remote carbon‐to‐carbon boryl migration via an intramolecular 1,4‐B/Cu shift, which establishes an in situ stereospecific electrophilic trap on the alkene moiety.

IEEE transactions on power electronics, 2018 This letter presents an inductive power transfer system based on a new variable coil structure to achieve load-independent constant current (CC) and constant voltage (CV) outputs for charging electric bicycles (EBs), without involving complex control ...
