An Empirical Analysis on Travel Characteristics of Feeder Trips Between Shared Electric Bicycles and Urban Rail Transit: A Case Study of Hohhot [PDF]
E3S Web of ConferencesThis study proposes a method for determining whether the purpose of cycling an electric bicycle is to transfer to a subway connection and then employs ArcGIS to set buffer zones of 250-meters radius and pick up the orders of connecting travel by judging ...

The Regulatory Role of Iron Transporter SLC39A13 in Liver Fibrosis
Advanced Science, EarlyView.SLC39A13/ZIP13, a newly discovered intracellular iron transporter, delivers iron to the ER/Golgi to catalyze procollagen hydroxylation during collagen maturation. Here, we systematically characterize the cell type‐specific functions of ZIP13 across distinct hepatic cell populations, and identify hepatic stellate cell‐specific ZIP13 as a promising and ...

Advanced Science, EarlyView.Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.
