We study an M/M/1/K queue where customers can reschedule their appointments. Rescheduled customers show up with higher probabilities, incurring lower no-show costs, but rescheduling also frees up slots that may not be filled later, leading to wasted service capacity and lower throughput. The...

Online marketplace participation is a strategy for reducing barriers for female entrepreneurs who qualify as persons with disabilities (PWDs). Adapting a framework focused on causal interaction, entrepreneurial action, and the sociocultural context, we analyzed data using a mixed-methods...

The rapid development of nanotechnology boosts the massive production and utilization of various nanoparticles (NPs). However, the NPs escaped into environments form emergent pollutants, which poses a potential threat to marine organisms and ecosystems. Due to their sessile filter feeding...

The application of cerium-manganese oxides (CeMn) in controlling exhaust gas from biomass combustion is greatly inhibited due to poor resistance to alkali metals. Herein, we report a smart strategy to circumvent the K poisoning problem of CeMn by physically coupling with ZSM-5, which exhibited...
