Deforestation frequently accompanies poverty, yet various antipoverty programs in many countries have exhibited mixed results in addressing deforestation. Poverty Alleviation Resettlement (PAR) stands out as one of the few government-led resettlement programs designed to alleviate poverty, offering comprehensive follow-up support for quality of life and employment after relocation. Our study uncovered empirical evidence of the PAR program's impact on forest quality.

The Yb,Y:(Ca,Sr)F laser delivers soliton pulses as short as 35 fs at 1056.7 nm, with an average output power of 182 mW at a repetition rate of ∼65.

Accurately assessing mental states-such as mental workload and fatigue- is crucial for ensuring the reliability and effectiveness of brain-computer interface (BCI)-based applications. Relying on signals from a limited brain region with low spatial resolution may fail to capture the full scope of relevant information. To address this, high-density diffuse optical tomography (HD-DOT), an emerging form of functional near-infrared spectroscopy (fNIRS) was employed in this study, which provides higher spatial resolution for hemodynamic measurements and enables the reconstruction of 3D brain images.
