Intrinsic backgrounds from Rn and Kr in the XENON100 experiment

European Physical Journal C: Particles and Fields, 2018
In this paper, we describe the XENON100 data analyses used to assess the target-intrinsic background sources radon ( ), thoron ( ) and krypton ( ). We detail the event selections of high-energy alpha particles and decay-specific delayed coincidences.

Differential Proteomic Analysis to Reveal the Mechanism of Heat Damage in Soybean Using a Data‐Independent Acquisition (DIA) Strategy

Food Safety and Health, EarlyView.
Heat‐stressed soybeans adapt to elevated temperatures through coordinate regulation of destructive and protective protein expression ‐ suppressing detrimental proteins while enhancing beneficial ones. ABSTRACT Soybean represents the largest imported agricultural product in China. Imported soybeans are typically transported via maritime shipping. During
