In this paper, we study a novel network design problem for the fourth-party logistics network (4PLN) to cope with accidental demand surges. A chance-constrained stochastic programming model is established to minimize the overall cost for 4PLN under service-level targets, where the stochastic...

Low-cost and eco-friendly auxiliary energy supply units to power gas sensors are of great significance to various fields. In this work, a gas sensor based on the PANI/NiCo 2 O 4 composite was powered by a gelatin-polyimide based triboelectric nanogenerator (GP-TENG) for the detection of NH 3 at...
