A Simulation Study for Optimal Pinhole Collimator Design in Gamma Camera Systems

Journal of Medical Physics
Background: The usage of a semiconductor detector with a pinhole collimator can provide high spatial resolution due to its high intrinsic resolution. However, the collimator system has low sensitivity due to the hole’s small diameter.

Widespread Sensitivity of Grassland Water Use Efficiency to Deep Soil Moisture on the Tibetan Plateau

Water Resources Research
Water use efficiency (WUE, the ratio of gross primary productivity to evapotranspiration (ET)) is a robust indicator of ecosystem response to climate change, with soil moisture serving as a crucial determinant. Soil moisture varies across soil layers due

Converters' Loading Balance and Stability Verification for Doubly-Fed Induction Generators

CSEE Journal of Power and Energy Systems
Back-to-back converters are the main components of a doubly-fed induction generator (DFIG). If the loadings of the rotor-side converter (RSC) and the grid-side converter (GSC) are balanced, the capacity and the cost of the DFIG will be reduced.
