For sales quota periods, one size doesn’t fit all

A new study by the University of Texas at Austin suggests that sales quota periods should be tailored to individual preferences. Low performers are more motivated by constant motivation, while high performers respond better to longer quota cycles. This implies that one-size-fits-all approach to sales compensation may not be effective.

Physisorption-assistant optoelectronic synaptic transistors based on Ta2NiSe5/SnS2 heterojunction from ultraviolet to near-infrared

Researchers developed physisorption-assistant optoelectronic synaptic transistors based on Ta2NiSe5/SnS2 heterojunction, demonstrating tunable synaptic functionality in broadband (375-1310 nm). The strategy utilizes gas molecule adsorption to extend carrier lifetime and improve NIR light performance.

Study finds dramatic boost in air quality from electrifying railways

A new study found that electrifying the Caltrain commuter rail line reduced riders' exposure to black carbon by an average of 89%, cutting excess cancer deaths by 51 per 1 million people. The study's findings support the case for electrifying U.S. rail systems, which still rely on old diesel locomotives.
