AbstractThis paper considers uplink and downlink transmissions in a network with radio frequency-powered Internet of Things sensing devices. Unlike prior works, for uplinks, these devices use framed slotted Aloha for channel access. Another key distinction is that it considers uplinks and downlinks scheduling over multiple time slots using only causal information.

AbstractModes of climate variability can affect weather extremes, posing intractable challenges to our environment. However, to what extent climate modes can modulate heatwaves in China under a warming background remains poorly understood.

3.3 Projected Future Changes in Heatwave Characteristics To evaluate the future multi-aspect variations of heatwave events, we investigate the temporal evolutions of four heatwave indices in each sub-region during the period of 2020–2100 (Figure 3). The heatwave characteristics projected in SSP2-4.5 and SSP5-8.5 are shown in the middle and right columns. For comparison, the historical heatwave variations averaged over the period of 1981–2010 of each sub-region are shown in the left column.

3. Results and Discussion 3.1. Temporal Variation Characteristics presented the temporal change trend of the annual average PM2.5 concentration in the YREB and three regions from 2003 to 2018. From the overall perspective of the YREB, the average PM2.5 concentration from 2003 to 2018 was 48.18 μg/m3. It presented an inverted V-shape trend from 2003 to 2018, which rose from 45.09 μg/m3 in 2003 to 57.38 μg/m3 in 2011, and then declined to 34.77 μg/m3 in 2018.
